Description

Liquid sprayer

Technical Field

The present invention relates to a liquid sprayer, and more particularly, to a liquid sprayer which sucks in liquid contained in a liquid storage container by a pressure difference and discharges the liquid together with air.

Background

Liquid spray systems are widely used in various industrial fields, for example, spraying water or agricultural chemicals on crops, spraying paints in the fields of ships and buildings, and sprinkling water on roads, and the like, and the applications thereof are very many.

A typical liquid sprayer uses a spray method in which a liquid is directly pumped by a pump and sprayed through a nozzle at the front end, or a liquid in a liquid storage container is sucked by a pressure difference with air flowing through a venturi tube at a high speed and sprayed together with the air. An example of a sprayer that directly sprays by a pump-out method is a sprayer described in patent document 1.

A sprayer adopting a method of sucking a liquid by a pressure difference and discharging the liquid together with air is disclosed in patent document 2. In the nebulizer described in patent document 2, since the spraying direction depends on the mixing discharge pipe and the liquid discharge pipe, it is difficult to change the spraying direction. Further, since the mixing discharge pipe as an air passage pipe is exposed to the outside and the mixing discharge pipe is coupled to the nozzle body by a coupling cap, when the mixing discharge pipe and the nozzle body are separated, the liquid discharge pipe disposed inside may be exposed to the outside and the liquid discharge pipe may be detached from the nozzle body, so that it is difficult to replace the mixing discharge pipe. Further, since the liquid discharge pipe is directly connected to the nozzle body without a connector, when the liquid discharge pipe is separated from the nozzle body in order to replace the liquid discharge pipe, the interior of the nozzle body is exposed, and foreign substances may flow into the nozzle body, thereby causing a malfunction of the atomizer.

The upper tube 220 has the smallest diameter and inner diameter and the lower tube 240 has the largest diameter and inner diameter. Therefore, as shown in fig. 16, two lands are formed inside the adapter body 210, which can engage with the body 50 connected to the inlet of the container body 11, due to the difference in inner diameter. The upper and lower lengths of the upper tube 220 are the longest and the downward length of the middle tube 230 is the shortest.

An internal thread portion 221 is provided on the inner peripheral surface of the upper tube, and the internal thread portion 221 is screwed to an external thread portion formed in the liquid storage container 10. A second switch pcb support 223 is provided on the front side of the outer peripheral surface of the upper pipe 220, and a switch pcb (cp) connected to the power switch 320 and pcb (p) is inserted into and supported by the second switch pcb support 223.

The second switch pcb support portion 223 is formed of left and right side members, which protrude forward and extend with their ends bent perpendicularly in opposite directions. The second switch pcb support 223 has an open front and upper portion, and a lower end contacting the middle tube 230 and a closed lower portion. Therefore, the switch pcb (cp) is inserted downward from the opened upper portion of the second switch pcb support 223 and supported.

A partition plate protrusion 225 is provided on an outer circumferential surface of the upper pipe 220 in a vertical direction, and an internal thread portion screwed with a bolt (not shown) is provided on the partition plate protrusion 225 to couple and support the partition plate 260.

The lower end of the partition plate protrusion 225 is in contact with the middle tube 230. The partition plate projections 225 are provided in a total of 3, and are disposed on the outer peripheral surface of the upper pipe 220 at equal intervals centering on the center axis of the upper pipe 220.

Further, a coupling groove 241 is provided on the outer peripheral surface of the lower pipe 240, and a boss 15 provided on the inner surface of the container case 13 is engaged with the coupling groove 241.

When the adapter body 210 and the liquid container (10) are coupled, the lower tube 240 of the adapter body 210 is inserted into the liquid container 10, and then the adapter body 210 or the liquid container 10 is rotated so that the protrusion 15 of the container case 13 is positioned inside the coupling groove 241, thereby stably maintaining the coupling.

In order to achieve the effect of stably maintaining the connection, coupling groove 241 is composed of a dummy assembly groove 243 formed upward from the lower end of lower pipe 240 and a support groove 245 provided in the outer circumferential direction from the upper side of dummy assembly groove 243.

The lower tube 240 is also provided with a flange 247 along an upper end edge. Flange 247 projects slightly upward relative to lower tube 240. The upper surface of the flange 247 contacts the lower side of the vessel coupling portion 321 of the lower body 300, and the inner surface of the flange 247 contacts the upper side of the vessel shell 13. That is, the flange 247 prevents direct contact between the body 50 and the reservoir 10.

A body coupling boss 249 is protrudingly provided on an upper surface of the lower tube 240. The body coupling boss 249 is cylindrical and is disposed on the side of the outer peripheral surface of the middle tube 230.

As shown in fig. 2 and 15, the liquid storage container 10 includes: a container body 11 and a container case 13 accommodating the container body 11.

The container body 11 has no joint portion, and therefore, liquid leakage does not occur.

The vessel body 11 and the vessel shell 13 have a space therebetween at a distance in which the lower end of the lower tube 240 of the adapter body 210 is fitted.

The size of container body 11 according to the present embodiment is such that it does not come into contact with the inner circumferential surface of lower tube 240 when coupled to adapter body 210.

The liquid sprayer of the present invention can be used in connection with container bodies 11 of various shapes because of having the adapter body 210.

The shielding plate 260 has a substantially disk shape corresponding to the shape of the upper pipe 220. The shielding plate 260 prevents the liquid contained in the liquid storage container 10 from leaking to the main body 50 side. The partition plate 260 has 3 bolt insertion portions 265 protruded on an outer circumferential surface thereof. The bolt insertion portion 265 is disposed to correspond to the shielding plate protrusion 225, and when a bolt (not shown) is inserted through the bolt insertion portion and is screwed to the shielding plate protrusion 225, the shielding plate 260 and the adapter body 210 are coupled.

The shielding plate 260 is provided with a second switch pcb support 267 for supporting the upper side of the switch pcb (cp).

The second switch pcb support portion 267 extends upward on the upper surface of the blocking plate 260 and is bent vertically forward. A rib connected to the upper surface of the shielding plate 260 is further provided on the rear surface of the second switch pcb support 267. The second switch pcb support 267 is positioned above the second switch pcb support 223 to prevent the switch pcb (cp) from being separated upward.

The partition plate 260 is provided with a liquid flow path penetrating in the axial direction, and an upper hose connection pipe and a lower hose connection pipe connected to the upper hose 21 and the lower hose 23, respectively, are connected to the upper end and the lower end of the liquid flow path. An upper hose 21 connected to the nozzle 1000 is fitted over the upper hose connection pipe, and a lower hose 23 communicated with the inside of the liquid storage container 10 is fitted over the lower hose connection pipe. The upper hose connection pipe is provided on an upper surface of the partition plate 260, and the lower hose connection pipe is provided to protrude from a lower surface of the partition plate 260.

Further, a gasket groove 281 into which a ring-shaped gasket is inserted is provided on an inner surface of the partition plate 260. The lower hose connection pipe, the fixing hole 261, and the exhaust hole 263 are disposed inside the gasket groove.

When the container adapter 200 and the liquid storage container are coupled, the opening of the container body 11 is spaced apart from the partition plate 260 by a predetermined distance, thereby creating a gap. In this case, the gasket is disposed so as to close the gap. Therefore, the liquid does not leak from the container adapter 200, and flows to the lower hose 23 through the upper hose 21.

The blocking plate 260 is provided with a fixing hole 261 for inserting the valve body 291 therethrough, and an air discharge hole 263 located on a side of the fixing hole 261.

The fixing hole 261 and the exhaust hole 263 are located at the side of the center of the partition plate 260 when viewed from the upper surface or the lower surface of the partition plate 260 toward the front. The center axes of the fixing hole 261 and the exhaust hole 263 are arranged in parallel with the center axis of the liquid oil passage in the left-right direction.

The fixing hole 261 has a diameter larger than that of the discharge hole 263.

When the liquid sprayer is operated, the air of the body 50 is exhausted to the liquid storage container 10 through the exhaust hole 263.

The check valve 290 has: a cylindrical valve body 291 inserted into and supported by the fixing hole 261, a head 293 formed at an end of the valve body 291 and contacting an inner surface of the blocking plate 260, and a stopper 295 formed at a substantially central portion of the valve body 291 and capable of preventing the downward separation of the check valve 290.

The provision of such a check valve 290 has the following effects: when the liquid sprayer is operated, air flows into the container body 11 through the opening through the gap generated by the air flow while pushing the head 293 downward through the air vent holes 263, and when the liquid sprayer is stopped, the head 293 closes the air vent holes 263 to block the opening, so that the liquid in the liquid storage container 10 does not leak to the side or the outside of the body 50, thereby facilitating the use.

The nozzle 1000 has: a fluid passage member 700 connected to the main body 50, and a discharge member 800 connected to the fluid passage member 700 so as to communicate with the fluid passage member.

The nozzle 1000 includes: an air passage 721 communicating with the discharge port OP of the Air Compressor (AC) and the liquid reservoir 10, respectively, a fluid passage member 700 provided with a liquid passage 711, and a discharge member 800 inserted into the housing space 705 provided in the fluid passage member 700 and spraying the liquid.

In the following, for convenience of understanding, the liquid passage 711 of the fluid passage member 700 is referred to as a fourth liquid passage, and the air passage 721 is referred to as a fourth gas passage.

The outer body 803 is provided with a first screw portion 881, the fluid passage member 700 is provided with a second screw portion 723 screwed with the first screw portion 881, the inner body 801 is provided with a third screw portion 831, and the fluid passage member 700 is provided with a fourth screw portion 713 screwed with the third screw portion 831. Therefore, when the discharge part 800 is broken, it is easy to replace, and it is easy to assemble and disassemble the discharge part 800 and the fluid passage part 700. That is, assembly and maintenance of the nozzle 1000 are easy. The bolt portions will be described in detail below.

The nebulizer of the present invention further comprises: a nozzle connector 400 detachably coupled to the nozzle 1000 and coupled to the main body 50, a nozzle housing 900 accommodating the discharge member 800 and the fluid passage member 700, and a housing connector 500 detachably coupled to the nozzle housing 900 and the nozzle connector 400, respectively.

The nozzle 1000 of the present invention further includes: an inner connector 600 coupled to the fluid passage member 700 and accommodated inside the nozzle housing 900, and a housing connector 500 coupled to the inner connector 600 and the nozzle connector 400 to block the opened rear side of the nozzle housing 900.

In the present embodiment, the nozzle 1000 includes a discharge part 800, a fluid passage part 700, an inner connector 600, a housing connector 500, and a nozzle housing 900.

The nozzle 1000 of the present invention can be separated from the body 50, improving convenience of replacement and a/S, and can be connected to nozzles of various shapes, improving usability of the present invention.

The end of the nozzle 1000 may be in the shape of a straight line or may be bent at an angle of 45 degrees or 90 degrees with respect to the stator 12

The liquid can be sprayed in various directions by the font. In this embodiment, a linear nozzle 1000 having a straight line shape is applied.

As shown in fig. 4a and 10, the nozzle connector 400 is provided with a first liquid passage 411 connected to the liquid storage container 10 and a first air passage 421 connected to the discharge port of the Air Compressor (AC), respectively.

When the nozzle connector 400 is viewed from the front or rear side of the nozzle connector 400 in the front direction, the nozzle connector 400 has an elliptical shape having a substantially long length in the vertical direction, and the thickness in the front-rear direction increases as the nozzle connector moves from the upper side to the lower side with reference to fig. 4 a.

The outer shape of the nozzle connector 400 corresponds to the nozzle connector upper receiving portion 120 and the nozzle connector lower receiving portion 305 of the body 50.

The first liquid passage 411 and the first air passage 421 are provided so as to penetrate the nozzle connector 400 in the front-rear direction.

The first liquid passage 411 is disposed substantially above the center of the nozzle connector 400, and the first air passage 421 is disposed below the center of the nozzle connector 400.

In addition, a first liquid pipe 420 for connecting the upper hose 21 and a first air pipe 430 for inserting a discharge port of an Air Compressor (AC) are provided at a central portion of the rear surface of the nozzle connector 400. The front-rear length of the first air pipe 430 is shorter than the first liquid pipe 420. The first liquid pipe 420 is disposed on the upper side of the first air pipe 430.

On the front side of the nozzle coupler 400, a second rear liquid pipe insertion part 412 and a second rear air pipe insertion part 422 for inserting a second liquid pipe and a second air pipe, which will be described later, respectively, are formed with a front surface thereof recessed.

The first liquid passage 411 is formed inside the first liquid pipe 420 and also inside the second rear liquid pipe insertion part 412, and the first air passage 421 is formed inside the first air pipe 430 and also inside the second rear air pipe insertion part 422.

In addition, the left and right sides of the rear surface of the nozzle connector 400 are deeply recessed to form a protrusion receiving portion 410 that receives the front side of the upper protrusion 149 and the front side of the lower protrusion 301.

A projection receiving part 410 is formed in a portion from the upper end to the lower end of the nozzle connector 400.

In addition, a support post insertion hole 440 for inserting the support post 307 of the lower body 300 is provided on the inner surface of the nozzle connector 400. The support post insertion holes 440 are provided in two in total, that is, one between the left boss receiving part 410 and the connection pipe and one between the right boss receiving part 410 and the connection pipe. The support post insertion hole 440 is disposed on the front side of the boss accommodating portion 410.

The nozzle connector 400 is provided with a boss insertion hole 450 into which a rear boss 501, which will be described later, is inserted to maintain the connection between the nozzle connector 400 and the housing connector 500.

The nozzle of the present embodiment has a shape for spraying the liquid slightly upward, that is, in order to realize this spraying feature, the first liquid passage 411 and the first air passage 421 are provided so as to be inclined upward as they move from the vicinity of the central position toward the front side.

The shape of the nozzle connector 400 or the direction in which the first liquid passage 411 and the first air passage 421 penetrate can be set differently depending on the desired spray direction. The nozzle connector 400 is made of a rubber material, which facilitates assembly and replacement with the housing connector 500 or the body 50.

As shown in fig. 2 to 4a and 9, the housing connector 500 is provided with a second liquid passage 511 and a second air passage 521 which communicate with the first liquid passage 411 and the first air passage 421 of the nozzle connector 400 in the front-rear direction, respectively.

The generally disk-shaped housing connector 500 includes a coupling flange disposed along the edge in the forward direction. The connecting flange has: an outer flange 507 disposed outside, and an inner flange 509 having a smaller diameter than the outer flange 507. Since the outer flange 507 is shorter in length than the inner flange 509, the inner flange 509 protrudes forward from the outer flange 507. Accordingly, a flange is formed on the coupling flange, and the inner surface of the nozzle housing 900 is formed in a shape corresponding to the coupling flange. That is, the housing connector 500 can be pseudo-assembled with the nozzle housing by using the flange.

The housing connector 500 is provided with a bolt insertion hole 503 through which a bolt (not shown) is inserted so that the assembly of the housing connector 500 and the nozzle housing 900 is completed. Accordingly, it is preferable that a connector boss 925 is provided at a position corresponding to the bolt insertion hole 503 in the nozzle housing 900, and the bolt (not shown) is screwed to the connector boss 925.

Further, the housing connector 500 further includes: a second rear liquid pipe 531 and a second rear air pipe 532 respectively inserted into the front side of the first liquid passage 411 and the front side of the first air passage 421 of the nozzle connector 400.

The second rear liquid pipe 531 and the second rear air pipe 532 are formed to protrude from the rear surface of the case connector 500 to the rear side, respectively.

The housing connector 500 is provided with a second front-side liquid pipe 541 and a second rear-side liquid pipe 531 inserted into the inner connector 600.

The second liquid passage 511 is also formed in the second rear liquid pipe 531 and the second front liquid pipe 541, and the second air passage 521 is also formed in the second rear air pipe 532 and the second front air pipe 542.

In addition, the front surface of the housing connector 500 is provided with left and right protrusions 505 inserted into the second front liquid pipe 541 and the inner connector 600.

A rear projection 501 inserted into the nozzle connector 400 is provided on the rear surface of the housing connector 500.

The inner connector 600 as shown in fig. 3 and 4a is substantially right hexahedral in shape. The interconnectors 600 are provided in a total of 4, that is, 1 on each of two corners on the upper side and lower sides of two side surfaces of the protrusion receiving groove 601 receiving a part of the connector protrusion 925 of the nozzle case 900.

The vertical cross section of the upper protrusion receiving groove 601 is approximately 1/4 circular, and the vertical cross section of the lower protrusion receiving groove 601 is semicircular.

The inner connector 600 is provided with a third liquid passage 611 and a third air passage 621 penetrating in the front-rear direction.

In addition, as shown in fig. 8, a second front liquid pipe insertion part 612 and a second front air pipe insertion part 622 for respectively inserting the second front liquid pipe 541 and the second front air pipe 542 are provided on the rear surface of the inner connector 600.

The second front side liquid pipe insertion part 612 is configured to surround the third liquid passage 611 at a distance from the third liquid passage 611, and the second front side air pipe insertion part 622 is configured to surround the third air passage 621 at a distance from the third air passage 621.

Further, a straight tube insertion portion 631 and an inclined tube insertion portion 633 for inserting a straight tube 703 and an inclined tube 701 of the fluid passage member 700 described later are provided on the front surface of the inner connector 600.

The third liquid passage 611 is also formed in the straight tube insertion portion 631, and the third air passage 621 is also formed in the inclined tube insertion portion 633.

Further, a front protrusion insertion hole 603 for inserting the front protrusion 505 of the housing connector 500 is provided in the inner connector 600 to penetrate in the front-rear direction. The front protrusion insertion holes 603 are disposed at positions corresponding to the front protrusions 505, and are disposed one on each of the left and right sides of the second front liquid tube insertion part 612.

Since the inner surface of the second case 920 of the nozzle case 900, which will be described later, is curved, a portion of the lower front corner of the inner connector 600 is curved so as to be attached to the second case 920 to the maximum extent. Thereby, the inner connector 600 is completely inserted into the nozzle housing 900 and can be stably supported.

The front surface of the inner connector 600 contacts the inner surface of the nozzle housing 900, and the rear surface contacts the front surface of the housing connector 500. Accordingly, the inner connector 600 is stably supported inside the nozzle housing 900, and the fluid passage member 700 and the housing connector 500 can be stably connected.

The inner connector 600 is prepared using a rubber material so as to facilitate assembly and replacement operations with the fluid passing member 700 and the housing connector 500.

The fluid passage member 700 shown in fig. 3 to 5 is formed by connecting 1 straight pipe 703 and one inclined pipe 701 arranged in parallel substantially in the front-rear direction.

More specifically, the fluid passage member 700 is provided with a fourth fluid passage 711 communicating with the liquid storage container 10, and a fourth air passage 721 communicating with the discharge port of the Air Compressor (AC).

A fourth liquid passage 711 is formed in the straight tube 703, and a fourth air passage 721 is formed in the inclined tube 701. The inner diameter of the fourth liquid passage 711 is larger than that of the fourth air passage 721. The fluid passage member 700 is provided with a housing surface forming a housing space 705 on the front side. The front of the fluid passage member 700 is opened by the housing space 705, and the rear thereof is opened by the fourth liquid passage 711.

A part of the side of the housing space 705 communicates with the fourth air passage 721.

As shown in fig. 4a and 4b, the housing space 705 is disposed forward of the fourth liquid passage 711, and the rear side thereof communicates with the fourth liquid passage 711. The diameter of the housing space 705 is larger than the diameter of the fourth liquid passage 711.

As shown in fig. 4a and 4b, the fluid passage member 700 is provided with a fourth screw portion 713 as a female screw portion, which is coupled to the inner body 801 of the discharge member 800, and a second screw portion 723 as a female screw portion, which is coupled to the outer body 803 of the discharge member 800, is provided on a side of the fourth screw portion 713.

The second screw portion 723 is disposed on the front side of the fourth air passage 721 and substantially in the center of the housing surface forming the housing space 705.

The fourth screw portion 713 is a portion of the inner circumferential surface forming the fourth liquid passage 711.

As shown in fig. 4b, after the nozzle 1000 is assembled, an air inflow space 740 surrounded by the inner body 801 and the outer body 803 and communicating with the fourth air passage 721 is formed on the receiving space 705 of the fluid passage member 700. The air inflow space 740 is formed between the hooking flange 829 of the inner body 801 and the second screw portion 723 of the outer body 803, and is surrounded by the inner circumferential surface of the fluid passage member 700 and the first body portion 810 of the inner body 801.

Further, a straight tube insertion tube 731 and an inclined tube insertion tube 733 to be inserted into the inner connector 600 are provided on the rear side of the straight tube 703 and the rear side of the inclined tube 701 of the fluid passage member 700, respectively.

The straight tube insertion tube 731 and the sloped tube insertion tube 733 are inserted into the straight tube insertion portion 631 and the sloped tube insertion portion 633, respectively.

Further, coupling ribs 741 extending in the front-rear direction are formed on the upper side, the left side, and the right side of the straight tube 703, respectively.

The width of the coupling rib 741 becomes wider as moving from the front side to the rear side to correspond to the shape of the nozzle housing 900.

The coupling rib 741 is inserted into a space formed by an accommodating protrusion 915 provided on an inner surface of the nozzle housing 900, which will be described later. Thus, the fluid passage member 700 is inserted into the nozzle housing 900 without rotating, and the position thereof can be fixed.

As shown in fig. 3 to 5, the discharge member 800 includes: the outer body 803 and the inner body 801.

As shown in fig. 3 to 5, the substantially cylindrical inner body 801 includes: the first body portion 810 inserted into a receiving space 705 of the fluid passage member 700 and a body receiving hole 861, which will be described later, of the outer body 803, an exposed portion 833 projected from a front end portion of the first body portion 810, projecting portions 820 provided in front of the first body portion 810 in both side directions, a mounting flange 829 provided on a rear side close to the first body portion 810, the third screw portion 831 provided as a male screw connected to a rear end portion of the first body portion 801, and a fifth liquid channel 811 provided to penetrate the entire inner body 801 in the front-rear direction.

The front side of the first body 810 moves forward and becomes smaller in outer diameter, and finally, is connected to the exposed portion 833. The diameter of the exposed portion 833 is smallest among the constituent members of the internal body 801.

A liquid outlet 815 communicating with the fifth liquid channel 811 and the mist inducing portion 871 is provided in the inner body 801 to penetrate in the front-rear direction.

A liquid discharge port 815 is provided at one end of the fifth liquid channel 811, that is, formed on the front-side end portion of the fifth liquid channel 811.

The protrusion 820 is provided along the outer circumferential surface of the first body part 810 with a certain thickness.

The number of the protruding portions 820 is 2, and an air discharge induction groove 825 is provided between the mutually facing sides of the two protruding portions 820 in the air discharge direction in the inner body 801. Thus, when the fluid passage member 700 and the discharge member 800 are coupled, the air discharge-inducing groove 825 widens the interval distance between the outer body 803 and the inner body 801, so that the air flows more smoothly through the air discharge-inducing groove 825.

A gasket groove (reference numeral is not shown) for fitting the annular gasket 835 is provided between the hanging flange 829 and the third screw portion 831.

As shown in fig. 4a and 4b, the gasket 835 contacts a boss 750 formed on the inner circumferential surface of the fluid passage member 700, and closes a gap between the hanging flange 829 and the boss 750. Thus, liquid does not leak out from between the inner body 801 and the fluid passage member 700. To prevent water leakage, the inner diameter of the gasket 835 is preferably smaller than the outer diameter of the hooking flange.

As shown in fig. 3 to 5, the substantially cylindrical outer body 803 has, in the front-rear direction: a second body 870 protruding from the nozzle housing 900 to be exposed, a third body 880 connected to the rear side of the second body 870 and housed in the front opening of the nozzle housing 900 and the housing space 705 of the fluid passage member 700, and a through hole including a spray-inducing portion 871 and the housing portion 860 communicating with each other.

One end of the outer body 803 is provided with a spray-inducing portion 871 whose width is widened as it moves toward the end, and the spray-inducing portion 871 communicates with the accommodating portion 860.

The penetration hole of the outer body 803 further includes: an exposed portion insertion hole 862 provided in the second body portion 870 so as to communicate the accommodation portion 860 and the spray-inducing portion 871.

The receiving portion 860 of the outer body 803 has: a body housing hole 861 for housing the first body 810 of the inner body 801, and an exposed portion insertion hole 862 for inserting the exposed portion 833 therethrough.

The body housing hole 861 has a diameter larger than the exposed portion insertion hole 862. The front side of the body housing hole 861 communicates with the exposed portion insertion hole 862, and the rear side of the body housing hole 861 communicates with the air inflow space 740. Accordingly, the air is discharged from the fourth air passage 721, passes through the air inflow space 740, the body housing hole 861, and the exposed portion insertion hole 862, and is finally discharged to the outside through the spray-inducing portion 871.

When the internal body 801 is inserted into and accommodated in the body accommodating hole 861 of the external body 803, as shown in fig. 4a and 4b, one end of the fifth liquid channel 811 of the internal body 801 is arranged to be positioned further to one side than the accommodating portion 860, that is, in front of the accommodating portion 860, and is accommodated in the spray-inducing portion 871. That is, since the exposed portion 833 is inserted through the exposed portion insertion hole 862 of the outer body 803, the liquid discharge port 815, which is the front end portion, is disposed on the front side of the exposed portion insertion hole 862 and is accommodated in the mist inducing portion 871.

At this time, the exposed portion insertion hole 862 is surrounded by the mist inducing portion 871, and the liquid discharge port 815 of the exposed portion 833 is surrounded by the exposed portion insertion hole 862.

The front surface of the second body portion 870 is recessed inward to form a spray-inducing portion 871, and the spray-inducing portion 871 is a space formed by an inclined surface 873 inclined inward as it moves from the front side to the rear side, and an inner circumferential surface 879 connected to the inner circumferential surface where the inclined surface 873 and the exposed portion insertion hole 862 are formed in a perpendicular manner. Accordingly, the spray-inducing portion 871 has a wider width as the distance from the liquid outlet 815 is increased, that is, as the distance is increased toward the front side in the spraying direction.

At this time, as described above, the inner circumferential surface 879 forming the mist inducing portion 871 is disposed at one end of the exposed portion 833, that is, in parallel with the front end, and at a position rearward of the one end of the exposed portion 833 so that the one end of the fifth liquid channel 811 is accommodated in the mist inducing portion 871. Thus, when the liquid sprayer is operated, the liquid can be sprayed over a wide range all around, rather than being sprayed in a linear direction.

In this case, when the nozzle 1000 is viewed from the front, the exposed portion insertion hole 862 has an annular cross section, and the liquid discharge port 815 has a circular cross section. As shown in fig. 4c, the distance (AD) between the inner peripheral surface where the exposed portion insertion hole 862 is formed and the outer peripheral surface of the exposed portion 833 in the lateral direction is preferably equal to the diameter (LD) of the liquid discharge port 815. In the present embodiment, the distance (AD) between the inner peripheral surface where the exposed portion insertion hole 862 is formed and the outer peripheral surface of the exposed portion 833 in the lateral direction is 0.1mm, and the diameter (LD) of the liquid discharge port 815 is 0.1 mm.

The second body 870 is provided with a plurality of grooves (not shown) at regular intervals along the outer peripheral surface thereof so as to be grasped by a hand or a tool and rotated for unlocking.

In addition, as in the inner body 801, the third body 880 is provided with a groove 883 along the outer peripheral surface thereof for fitting an annular gasket (not shown). In the present embodiment, two washers (not shown) are fitted to the third body 880.

In the third body 880, the first screw 881 is provided as an external screw on the rear side of the groove 833 into which the washer (not shown) is fitted.

The third body 880 has an outer diameter smaller than the outer diameter of the second body 870. Thus, when the outer body 803 and the nozzle housing 900 are coupled, the second body 870 having a large outer diameter is engaged with the nozzle housing 900, and the outer body 803 is not inserted into the fluid passage member 700 to a certain depth or more, thereby facilitating assembly.

As shown in fig. 2 to 4a, the nozzle housing is substantially cylindrical. More specifically, the nozzle housing has: a first housing 910 for inserting and housing the discharge member 800 and the fluid passage member 700, and a second housing 920 for inserting and housing the internal connector 600 and coupled to the housing connector 500. The diameter of the first case 910 is larger than that of the second case 920.

The first housing 910 is composed of a front side portion and an outer peripheral portion. The front side of the first housing 910 engages with the second body 870 of the outer body 803 and surrounds the outer peripheral surface of the third body 880. The receiving protrusions 915 for fitting the ribs of the fluid passage member 700 are provided on the upper side, the left side and the right side of the outer circumferential portion of a case 910, respectively.

The second case 920 is composed of a front side portion and an outer peripheral portion. The second housing 920 is provided with the connector projection 925 projecting rearward. In the present embodiment, the connector projection 925 is formed on the entire front side portion and the outer peripheral portion of the second case 920. A flange 927 forming a boss is provided on the edge of the rear surface of the second housing 920 so as to be engaged with the housing connector 500 for assembly.

In the nozzle 1000 of the present invention having the above-described structure, since the liquid passages 411, 511, 611, 711, and 811 and the air passages 421, 521, 621, and 721 are formed in a straight line structure, the internal structure can be easily confirmed, and the nozzle can be quickly repaired when a damage occurs, thereby facilitating the use of the liquid sprayer of the present invention.

Next, an embodiment of an assembling method of the disassembled structure of the present invention shown in fig. 2, 3, and 15 will be described.

First, a method of assembling the body 50 and the nozzle connector 400 shown in fig. 2 will be described.

Then, the fluid passage member 700 is coupled to the front side of the inner connector 600.

Then, the fluid passing member 700 and the inner body 801 are joined. At this time, when the inner body 801 and the fluid passage member 700 are coupled to each other, the inner body 801 is inserted into contact with the boss, and the inclined tube insertion tube 733 is inserted into the fourth liquid passage 711 and coupled to the fourth screw portion 713.

Then, the inner body 801, the fluid passage member 700, the inner connector 600, and the housing connector 500, which are coupled to each other through the above-described process, are inserted into the nozzle housing 900.

A method of assembling the reservoir 10 and the container adapter 200 as described in fig. 2, 15, and 16 will be described.

The liquid container 10 and the adapter body 210 are joined.

Then, the switch pcb (cp) is inserted and fixed to the adaptor body 210.

Then, the check valve 290 is inserted and fixed to the partition plate 260.

Then, a bolt (not shown) is screwed into the adapter body 210 to connect the partition plate 260 and the adapter body 210.

After the liquid container 10 and the container adapter 200 shown in fig. 2 are assembled by the above-described process, they are coupled to the body 50, thereby completing the assembly of the present invention.

The operation of the liquid spray device of the present invention will be described below.

When the power switch 320 connected to the switch pcb (cp) is pressed, a signal is generated, and the signal is transmitted to the pcb (p), and the Air Compressor (AC) is started by the pcb (p) to which the signal is transmitted, and the Air Compressor (AC) discharges air to the discharge port while sucking air from the suction port.

At this time, the discharged air passes through the first air passage 421 of the nozzle connector 400, the second air passage 521 of the housing connector 500, the third air passage 621 of the internal connector 600, the fourth air passage 721 of the fluid passage member 700, the air inflow space 740, the body housing hole 861 and the exposed portion insertion hole 862 of the discharge member 800, and the spray-inducing portion 871 of the external body 803 in this order, and is discharged to the surrounding directions at high speed.

Since the air is discharged at a high speed so that the pressure in the spray inducing portion 871 becomes lower than the atmospheric pressure, the liquid contained in the liquid storage container 10 having a relatively high pressure rises through the liquid hose and is then discharged through the first liquid passage 411 of the nozzle connector 400 to which the upper hose 21 is connected, the second liquid passage 511 of the case connector 500, the third liquid passage 611 of the inner connector 600, the fourth liquid passage 711 of the fluid passage member 700, the fifth liquid passage 811 of the inner body 801, and the liquid discharge port 815 in this order, and at the moment of discharge from the liquid discharge port 815, the liquid is mixed with the compressed air in the spray inducing portion 871, so that the liquid is finely atomized in the external space, and the spraying effect is excellent.

The gasket 835 may be disposed in a manner different from that shown in fig. 4a and 4b, that is, may be disposed so as to contact the rear surface of the hanging flange 829 and the front surface of the boss 750.

While the preferred embodiments of the present invention have been described above, those skilled in the art can make various modifications and alterations to the present invention without departing from the spirit and scope of the present invention as disclosed in the following claims.
