Description

  The present invention relates to a simple liquid spraying apparatus, and more specifically, to a simple liquid spraying apparatus that can repeatedly spray a liquid such as a disinfecting / bleaching liquid that does not like contact with air without being brought into contact with air.

  Infectious diseases in hospitals and outbreaks in schools and nursing homes are often the subject of discussion. Elimination of infectious factors caused by bacteria and bacteria in these facilities is an important social need. Furthermore, in order to respond to the recent crisis due to the new influenza virus, etc., the disinfection device becomes more familiar and is desired to be widely spread to each home. As a liquid spraying device, a device that is easily available and can be used simply is known in the prior art.

  There is a device as disclosed in Patent Document 1 as a general one, put disinfectant solution or fragrance into the main body container, hold the device in hand, put the finger on the lever of the spray mechanism, and pull the finger Thus, the liquid in the main body container is sprayed from the nozzle to the outside by the action of the pump inside the spray mechanism. In these devices, each time the internal liquid is consumed, the external air is introduced into the main body container, and the reduced volume of the liquid in the main body container is replaced with air to keep the internal volume of the main body container constant, or the main body The pressure difference between the inside and outside of the container is prevented from occurring.

  By the way, sodium hypochlorite, cresol soap solution, alcohol, and the like have been widely used as disinfecting and bleaching solutions. On the other hand, in recent years, chlorine dioxide has attracted attention as a disinfecting and bleaching solution (for example, see Patent Document 2). Chlorine dioxide can be said to be a preferable drug in that it has a disinfecting and bleaching action by a strong oxidizing action and is completely harmless to human livestock. Disinfection and bleaching solutions in which chlorine dioxide is used as an aqueous solution are already on the market and are beginning to spread. In general, disinfectants having an oxidizing action can be used for bleaching as well as disinfection. In the description of the present specification, the description will be mainly related to disinfection, but this does not exclude the use for bleaching. In addition, “disinfection” here includes a broad concept such as “sterilization”, “sterilization”, and “disinfection”.

  Chlorine dioxide described above has very high potential as a disinfectant in terms of disinfection effect, safety, economy (low cost), but has a drawback that it is difficult to manage. In particular, it is easily decomposed by contact with high temperature and ultraviolet rays or by contact with air, and if it is decomposed, the medicinal effect is reduced. In particular, in order to be a disinfectant that can be used as a pharmaceutical product, it is required to prevent the decomposition of chlorine dioxide and to maintain its concentration constant. For example, when the liquid spraying apparatus shown in Patent Document 1 described above is used as a disinfecting liquid spraying apparatus using chlorine dioxide, air is filled instead in the bottle after the liquid is pumped by the operation of the pump. As a result, chlorine dioxide is decomposed and altered, or various germs in the air enter the bottle. Since the bottle is exposed and arranged in the environment, the temperature of the bottle rises as the temperature of the atmosphere rises, and further, ultraviolet rays in the atmosphere are exposed. That is, the liquid spray device in the prior art is not suitable for spraying a disinfectant such as chlorine dioxide.

  As described above, the present invention eliminates the above-mentioned problems of the prior art, can maintain the disinfection and bleaching effect even for liquids that are difficult to manage, such as chlorine dioxide, and can be easily operated. The purpose is to provide. However, the simple liquid spraying apparatus according to the present invention is not limited to use for chlorine dioxide or disinfecting / bleaching liquid, and can be used for other liquids that do not like contact with air. .

  The present invention puts a storage bag containing a liquid such as chlorine dioxide in a protective case to shield it from ultraviolet rays, and sprays a certain amount of liquid by operating a manual pump attached to the protective case, The reduction in the internal volume of the storage bag due to this can be solved by contracting the storage container without introducing air, thereby solving the above-described problems, and specifically includes the following contents.

  That is, one aspect according to the present invention is a liquid spraying device including a storage bag storing liquid, and a spray mechanism that attaches the storage bag and sucks the liquid from the storage bag and sprays the liquid to the outside. The spray mechanism is configured to pump a predetermined amount of disinfectant liquid while the operation unit is operated from the initial position to the spray position and spray the outside, while the operation unit returns from the spray position to the initial position. A liquid spraying apparatus, wherein a predetermined amount of a disinfectant is sucked from a storage bag, and the storage bag absorbs a change in internal volume accompanying a decrease in the amount of liquid due to suction by contracting its own volume without introducing outside air. About.

  Liquid pumping / spraying and liquid suction can be performed by the action between the cylinder and the piston that move relative to each other in accordance with the operation of the operation unit. The liquid can be sucked from the storage bag through a tube inserted into the storage bag, and the tube has one or more grooves extending in the axial direction of the outer periphery. A plurality of suction holes for sucking the liquid can be provided inside the groove. The said storage bag shall be provided with a bellows part in the trunk | drum side surface, and may be formed so that expansion-contraction is possible to an axial direction by the effect | action of this bellows part.

  The liquid spraying device may further include a protective case that covers at least a part of the exterior of the storage bag. It is preferable that a part of the protective case is openable so that the storage bag in the protective case can be replaced. The protective case can be formed of a light-shielding material that blocks ultraviolet rays or the like. Further, a heat insulating material can be attached to the protective case, or a cooling device composed of a battery and a Peltier element can be attached. The above liquid spray apparatus can be used as a disinfectant spray apparatus for spraying a chlorine dioxide aqueous solution.

  By implementing the simple liquid spraying apparatus according to the present invention, it becomes possible to repeatedly use a liquid such as a disinfecting / bleaching solution over a long period of time using a simple apparatus without deteriorating the liquid by contact with air. As a result, for example, a device capable of easily spraying a disinfectant can be widely spread from hospitals and care facilities to schools and homes.

It is side surface sectional drawing which shows the spray mechanism of the simple liquid spray apparatus shown in FIG. It is the perspective view and sectional drawing which show the structure of the tube of the spray mechanism shown in FIG. It is a side view which shows the condition at the time of the storage bag replacement | exchange of the simple liquid spraying apparatus shown in FIG. It is side surface sectional drawing which shows the simple liquid spraying apparatus which concerns on other embodiment of this invention.

  A simple liquid spraying apparatus according to a first embodiment of the present invention will be described with reference to the drawings. In the following embodiments, “simple liquid spraying device” (also simply referred to as “spraying device”) is indicated as “disinfection device”, “disinfecting liquid”, etc. as representative examples, The same applies to liquids that can be used for purposes. FIG. 1 shows the appearance of a spray device 1 according to the present embodiment. In the figure, the spray device 1 is attached to a protective case 10, a flexible storage bag 20 that is housed in the protective case 10 and stores a disinfecting liquid such as chlorine dioxide or other liquid, and the protective case 10. And a spray mechanism 30 for spraying the disinfectant in the storage bag 20.

  The protective case 10 has strength for allowing the entire disinfecting apparatus to stand on its own, protects the storage bag 20 accommodated therein, blocks ultraviolet rays as much as possible, has a heat insulating effect, and the user operates the spray mechanism 30. It is desired to be as light as possible so as to be able to withstand a hand-held type, while fulfilling the multiple functions of providing a holding portion. Specifically, it is preferably made of plastic. Alternatively, it may be made of metal such as aluminum. Unlike the device for spraying water or fragrance in the prior art, the protective case 10 itself is not filled with a liquid, and therefore may be of other types as long as it performs the above-described function. In addition, since the protective case 10 merely protects the storage bag 20 inside, if it is unnecessary, for example, a part of the bottom surface or the like can be removed. In the illustrated example, a heat insulating material is attached inside a plastic container.

  The storage bag 20 stores a liquid such as a disinfectant, and has sufficient strength to hold the liquid to be stored and at the same time flexible enough to withstand or contract itself according to the consumption of the liquid. The shrinkage at this time may be a rubber-like elastomer material, but may be formed, for example, so as to be formed into a bowl shape by being formed of a plastic film. When chlorine dioxide is used, the storage bag 20 is preferably one that blocks ultraviolet rays. For example, it is preferable to take measures such that an aluminum foil is laminated on a plastic film forming the bag. These materials are also known in the prior art, for example in confectionery packaging bags.

  An example of the structure of the spray mechanism 30 is shown in FIG. In the figure, the spray mechanism 30 includes a tube 31 including valves 32 and 33, a nozzle 35, and a pump mechanism 40. Both valves 32 and 33 are one-way valves. The valve 32 is located on the lower side of the drawing corresponding to the upstream side of the flow of the disinfecting liquid to be sucked and sprayed, and the valve 33 located on the upper side of the drawing corresponding to the downstream side. Both allow only the flow from upstream to downstream and close the reverse flow. The upstream side of the tube 31 extends into the storage bag 20 so as to suck the disinfectant solution, and the downstream side is connected to the nozzle 35. And between the both valves 32 and 33 of the tube 31, the pump mechanism 40 for attracting | sucking disinfectant liquid and pumping this is connected.

  The pump mechanism 40 includes a cylinder 41 that can store a disinfectant, a piston 42 that can move inside the cylinder 41 in a liquid-tight state, a return spring 43 that exerts an urging force on the piston 42, and a manual push-in for the piston 42. The lever 44 and a joining rod 45 that connects the lever 44 and the piston 42 are configured. The lever 44 is configured to be rotatable about the pin 46 in the illustrated example, but may be of a type that moves in parallel with the cylinder 41 along the guide.

  The operation of the spray mechanism 30 configured as described above is as follows. The user grasps the spray device 1 (see FIG. 1) and turns the finger to the lever 44 so that the lever 44 in the initial position is directed to the spray position in the right direction in the figure. Pull. The lever 44 rotates and pushes the piston 42 in the cylinder 41 to the right side of the figure via the connecting rod 45. As a result, the disinfecting liquid in the cylinder 41 is pressurized and the valve 32 on the upstream side is closed and pushed in. The disinfecting liquid thus produced flows toward the nozzle 35 by opening the valve 33 on the downstream side, and is sprayed to the outside from the nozzle 35. The spray amount of the disinfectant at this time can be set in advance by the effective stroke of the piston 42 that moves in the cylinder 41.

  When the user releases the pressing force of the finger applied to the lever 44 after spraying, the piston 42 moves to the left side in the drawing by the urging force of the return spring 43 and returns to the initial position. At this time, since the inside of the cylinder 41 becomes negative pressure, the downstream valve 33 is closed by the action of this negative pressure, and as a result of opening the upstream valve 32, the disinfecting liquid is sucked into the tube 31 and the cylinder 41 inside Is filled with disinfectant for the next spray. Thereafter, the above-described operation is repeated. Unlike the spraying device according to the prior art, only the disinfecting liquid is sucked from the storage bag 20 without introducing outside air when the piston 42 returns, so that the disinfecting liquid does not touch the air and deteriorate. And each time the disinfectant is digested, the storage bag 20 shrinks and shrinks its internal volume.

  FIG. 3A shows an example of a specific shape of the tube 31. The tube 31 sucks the disinfecting liquid from the storage bag 20 by the negative pressure action described above. However, the storage bag 20 is deflated with the consumption of the disinfecting liquid and approaches the tube 31 and further comes into contact. At this time, if a negative pressure is generated in the tube 31 for suction, the storage bag 20 itself is sucked, and there is a possibility that the suction hole of the tube 31 may be blocked. Can not be sucked. As a measure for preventing this, in the illustrated example, a groove 38 is dug in the longitudinal direction of the tube 31, and a large number of suction holes 39 are provided at the bottom of the groove 38. The number of the grooves 38 is arbitrary, and does not necessarily have to be parallel to the longitudinal direction, and may be provided in a spiral shape. In the case of a spiral shape, two grooves may be provided so as to intersect. Moreover, when extending in the longitudinal direction, a circumferential groove intersecting therewith may be additionally provided.

  FIG. 3B shows a cross section of the tube 31, and a suction hole 39 provided at the bottom of the groove 38 communicates with an inner cavity 37 that penetrates the axis of the tube 31. The width w of the groove 38 is a value that satisfies the relationship of w <d, where d is the diameter at the time of limit bending accompanying the rigidity of the storage bag 20. As a result, the storage bag 20 does not block the suction hole 39 even if a part of the groove 38 is blocked. If the disinfecting liquid is present inside the storage bag 20, the disinfecting liquid is connected to the suction hole 39 at any part between the tube 31 and the storing bag 20, and the disinfecting liquid can be sucked from the part. It is. In order to realize this, the tube 31 preferably extends over the entire length of the storage bag 20, and in addition, the groove 38 may also extend to the end face of the tube 31 as shown in FIG. preferable.

  FIG. 4 shows a situation when the storage bag 20 is replaced. In some cases, the deodorizer spraying device is disposable in the entire device, and since this disinfecting device has a simple structure, it cannot be made disposable, but from the viewpoint of effective use of resources. It is preferable to reuse. FIG. 4 shows an example in the case of such reuse, and here shows a mode in which only the storage bag 20 is replaced. In the conventional spraying apparatus, the liquid is directly injected into the protective case (or a container corresponding thereto). However, since the disinfection apparatus 1 according to the present embodiment uses the storage bag 20, the liquid is injected from the protective case 10. It is necessary to remove the storage bag 20 and replace it with a new one. In addition, since the new storage bag 20 is filled with the disinfectant and swells, for example, the storage bag 20 cannot pass through the narrow neck portion of the protective case 10, and the protective case 10 is generally covered with the neck portion as is generally present. It cannot be screwed.

  For this reason, in the example shown in FIG. 4, the protective case 10 is divided into a case portion 10 a fixed to the spray mechanism 30 and a lid portion 10 b attached to the case portion 10 a through the hinge portion 11 so as to be openable and closable. Yes. When the disinfectant in the storage bag 20 is used up, the user opens the cover portion 10 b of the protective case 10, pulls out the empty storage bag 20 from the tube 31, puts a new storage bag 20 on the tube 31, and the tube 31. The stopper 36 provided on the outer periphery of the lens is inserted and fixed. At this time, if the tube 31 has a flexibility to bend away from the protective case 10 as indicated by a broken line in the figure, it is convenient in terms of replacement work. After fixing the storage bag 20, the replacement operation is completed by closing the lid portion 10b. The case portion 10a and the lid portion 10b of the protective case 10 are preferably provided with snap mechanisms 12a and 12b that can be opened and closed with one touch.

  The replacement format shown in FIG. 4 is merely an example. For example, the lid portion 10b may be opened and closed not in the left-right direction but in the up-down direction. Or you may enable it to remove completely by a slide type. Also, the bottom surface of the protective case 10 may be opened and inserted from below. In an extreme case, the protective case 10 itself may be eliminated, and the spray mechanism 30 may be provided with a grip portion that can operate the lever 44. In this case, since the self-supporting property of the sterilizer 1 is lost, a hook or the like that can be hooked on a holding rack may be provided at any part of the spray mechanism 1.

  As another aspect, the protective case 10 and the storage bag 20 can be replaced together as an assembly. The user removes the protective case 10 and the storage bag 20 together with the neck portion of the spraying device 30 by a method such as twisting, and screws and attaches a replacement assembly. When screwing, the upstream portion of the tube 31 on the replacement assembly side may be screwed simultaneously into the downstream portion of the tube 31 on the spray mechanism 30 side.

  Next, a simple liquid spray apparatus according to a second embodiment of the present invention will be described with reference to the drawings. FIG. 5 shows the spraying device 2 of the present embodiment. In the drawing, the spraying device 2 includes a protective case 60, a storage bag 70 for storing a disinfectant liquid stored in the protective case 60, and storage. A spray mechanism 80 for spraying the disinfectant in the bag 70 is configured. The configuration and function of the protective case 60 are basically the same as those of the protective case 10 according to the previous embodiment. In the illustrated example, the case portion (upper) and the lid portion are screwed or snapped at the coupling portion 61. It is formed to be separable (downward).

  The main difference from the spraying apparatus 1 according to the previous embodiment is that the outer periphery of the storage bag 70 is formed in a bellows shape, and the decrease in the internal volume of the storage bag 70 due to the spraying of the disinfecting liquid is caused upward by the action of the bellows. It is in the point comprised so that it may absorb by contracting. The upper and lower surfaces 70a, 70b of the storage bag 70 are formed with a relatively thick plate thickness, and the bellows portion is not attracted to the suction hole 89 of the spray mechanism 80 due to the rigid action. If necessary, in order to increase the rigidity of the upper and lower surfaces 70a and 70b, plastic or cardboard may be attached only to the upper and lower surfaces. Others are the same as those of the storage bag 20 according to the previous embodiment.

  The spray mechanism 80 is functionally similar to the spray mechanism 30 according to the previous embodiment, and the compatibility between the two is maintained, but the structure is slightly different. In FIG. 5, the spray mechanism 80 includes a tube 81 including ball valves 82 and 83, a nozzle 85, and a pump mechanism 90. The ball valves 82 and 83 are functionally the same as the vane valves 32 and 33 according to the previous embodiment except that balls are used, and either of them may be used.

  The pump mechanism 90 has a different configuration, a cylinder 91 that can store a liquid such as a disinfecting liquid, a piston 92 that moves inside the cylinder 91 and moves the cylinder 91 in a liquid-tight state, and a piston 92 and a cylinder 91. And a button 94 for pushing in the cylinder 91 attached above the cylinder 91. The lever 44 (see FIG. 2) in the previous embodiment is abolished and is configured to push the shilling 91 toward the piston 92. For this reason, the disinfectant spray device 2 shown in the present embodiment is suitable for placement and use rather than for hand-held use. In the present specification, a part that functions as a trigger for a difference that causes the spraying operation such as the lever 44 and the button 94 to be collectively referred to as an “operation unit”.

  The operation of the spray mechanism 80 is basically the same as that of the spray mechanism 30 according to the previous embodiment. When the user pushes the button 94 as shown by an arrow, the cylinder 91 is lowered, and the liquid in the cylinder 91 is pressurized by the fixed piston 92 and flows downward from the hole opened in the piston 92. The upstream side valve 82 is closed by the action of the applied pressure, the downstream side valve 83 is opened, and the disinfectant is sprayed from the nozzle 85 to the outside. The spray amount of the disinfecting liquid at this time can be set in advance by the effective internal volume due to the stroke of the cylinder 41. When the user releases the finger from the button 94, the cylinder 91 moves upward by the action of the return spring 93 and returns to the initial position. The downstream valve 83 is closed by the negative pressure generated in the cylinder 91 during this time, the upstream valve 82 is opened, and the disinfecting liquid is sucked from the storage bag 70. The decrease in the content of the disinfectant solution due to this is absorbed by the bellows of the storage bag 70.

  When the liquid in the storage bag 70 is exhausted and the bellows is completely contracted, the storage bag 70 is removed and a new storage bag 70 filled with the liquid is attached. When this replacement is performed, the protective case 60 is first separated by the coupling portion 61, and the storage bag 70 can be accessed. The rest is the same as in the previous embodiment, and the used storage bag 70 is removed from the tube 81, and a new protective bag 70 is inserted and fixed to the stopper position of the tube 81 instead. Thereafter, the protective case 60 is assembled again to complete the replacement.

  In the present embodiment, a cooling device 62 including a battery and a Peltier element is attached inside the protective case 60. The Peltier element is known in the prior art, and a temperature reduction effect can be obtained with a small amount of electric power. In particular, when chlorine dioxide is used as the disinfecting solution, the disinfecting effect is reduced by the temperature rise, but the inside of the protective case 60 can be cooled by the action of the Peltier element so that the effectiveness of the disinfecting solution can be maintained for a long time. Become. If necessary, a temperature sensor and a simple control device can be attached at the same time, and a Peltier element can be used to maintain a preferable constant temperature. It is possible to attach a similar mechanism in the previous embodiment, but if it is not attached, it is desirable to take measures to prevent deterioration by storing it in a refrigerator while the device is not in use.

  The disinfection / bleaching apparatus and the management system for the apparatus according to the present invention are widely used in the industrial field of manufacturing, supplying, and selling medical products, medical devices, and household items for the medical field, nursing homes, hospitals, homes, and the like. be able to.
