The present invention relates to a purified external air inflow type spray that prevents contamination of the liquid filled in the container. More specifically, the liquid filled in the container is sprayed due to the pressing action of the pump cap, and the pump cap Close the injection flow path through which the liquid is sprayed when rising after the pressing operation of It is a technical field related to a purified outside air inflow type spray that can prevent contamination of the liquid filled inside the container by allowing it to be purified.

In general, a fluid injection device is a device capable of jetting a liquid or gas through a nozzle according to a user's manipulation, and is applied and used in various fields such as a sprayer, a sprayer, a cosmetic container, and an oral irrigator.

The most representative example using such a fluid injection device is a sprayer. A conventional sprayer is coupled to be movable up and down on the upper part of a container for storing a liquid such as water, and is coupled to be elastically supported in the upper direction and to the lower part. It consists of a spraying device installed with a liquid guide pipe, the lower part of which is immersed in the liquid stored in the container.

The sprayer as described above moves the spraying device in the lower direction, that is, when a pressing operation is performed, the pressure inside the container is increased and the liquid is moved along the liquid guide pipe, thereby being sprayed to the outside through the spraying device and , when the injection device is moved to the original shape of the elastic member, that is, in the upward direction, it is used as a principle in which external air is moved into the interior of the container along the flow path through which the liquid is sprayed.

However, in the conventional atomizer as described above, when the injection device is moved to the original shape, that is, upward, contaminants such as foreign substances penetrate into the interior of the container along the flow path through which the liquid is sprayed and stored inside the container. There was a problem that the liquid was contaminated.

Of course, it is rare that foreign substances directly penetrate through the fine injection holes formed in the nozzles installed in the injection device, but the pollutants contained in the external air are contained in the external air and easily penetrate into the inside of the container to contaminate the liquid, It is difficult to use the sprayer for a long period of time, and in particular, cosmetics or sterilizing liquids, which are easily altered, are vulnerable to contaminants contained in the outside air, which is a fatal disadvantage of their useful life.

Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 8 showing an embodiment of the present invention.

First, the purified external air inflow type spray of the present invention is installed in a container 10 filled with a liquid such as cosmetics or sterilizing liquid therein, and installed so as to be movable in the vertical direction on the upper part of the container 10, in the upper direction. The pump cap 20 installed so as to be elastically supported by It is configured to include a tube 30 that moves the filled liquid in an upward direction, and moves external air into the interior of the container 10 when the pump cap 20 is moved upward.

At this time, since the coupling structure of the container 10 and the pump cap 20 may be any structure of a fluid injection device such as a conventional atomizer or a spray injector, a detailed description will be omitted, and the pump cap 20 is The structure in which the pump cap 20 is elastically supported by the spring (not shown) in the upper direction is elastically supported by a spring (not shown) installed inside the container 10, regardless of any structure of the conventional fluid injection device. Therefore, detailed description will be omitted. Briefly, the lower part of the spring is supported by a support plate (not shown) provided on the inside of the container 10 , and the upper part is supported by the inner lower surface of the pump cap 20 to the pump. It may be configured to elastically support the cap 20 in the upper direction.

In addition, when the pump cap 20 is moved in the lower direction, that is, when it is pressed, the pressure inside the container 10 is increased to allow the liquid to move upward through the tube 30, so that the The liquid is moved through the connecting part 100 and the spraying part 200 to be described and sprayed through the spraying nozzle 250 installed at the front end of the spraying part 200 .

Specifically, the pump cap 20 is formed to protrude from the inner lower surface to form the connection passage 110 , and the injection hole 112 is formed through the upper front of the connection passage 110 , and the connection passage ( The connection part 100 through which the inlet hole 114 is formed through the upper rear of the 110, and the first injection passage 210 protruding in front of the outer periphery and communicating with the injection hole 112 of the connection passage 110 ) formed at the rear of the injection unit 200 and the outer periphery, and is configured to include an inlet groove 300 communicating with the inlet hole 114 of the connection flow path 110 .

In addition, the pump cap 20 is configured to include a base body (not shown) formed in a shape in which the lower part is opened, and the connection part 100 is a tubular shape protruding from the inner lower surface of the base body. is formed to form a connection flow path 110 , and the upper portion of the tube 30 is coupled to the lower portion, thereby penetrating the hollow of the tube 30 and the connection flow path 110 and the liquid stored in the container 10 . and external air introduced through the inlet groove 300 may be moved.

At this time, the tube 30 is fixedly coupled to the lower part of the connection part 100 and may be configured to move up and down together according to the vertical movement of the pump cap 20 , and in another embodiment, the inner side of the container 10 . It may be installed so that the upper part enters the connection passage 110 in a state of being fixed to the inside of the container 10 by a support plate provided in the When the vertical movement of (20) is performed, any structure may be used as long as the state connected to the lower portion of the connection part 100 is maintained so as to be able to communicate with the connection flow path 110 .

However, it is preferable that the tube 30 is installed so that the upper part is inserted inside the connection flow path 110 of the connection part 100 , which is the connection flow path 110 when the pump cap 20 is moved downward. ) by forming a narrow inner diameter, this is because it is possible to obtain the effect of allowing the moving liquid to move faster and to be sprayed smoothly.

In connection with the above, the connection part 100 is a tube when the pump cap 20 is pressed as the injection hole 112 formed in the upper front communicates with the first injection passage 210 of the injection unit 200 . The liquid moving through 30 can be smoothly moved to the first injection passage 210 through the connection passage 110 .

In addition, as the inlet hole 114 formed at the upper rear side communicates with the inlet groove 300 , the connection part 100 is connected to the pump cap 20 when the pump cap 20 is moved upward after a pressing operation through the inlet groove 300 . It allows external air to smoothly move into the interior of the container 10 through the connection passage 110 and the tube 30 .

At this time, the inlet hole 114 is preferably formed at a lower height than the injection hole 112 , which is a first that has not been injected after the liquid is injected through the injection nozzle 250 , which will be described in detail later. This is because, when the liquid in the injection passage 210 is moved back into the container 10 , it may not be moved smoothly by the incoming external air.

In addition, it is preferable that the inlet hole 114 has a larger diameter than that of the spray hole 112 , which is the amount of liquid in which external air introduced after the liquid is sprayed moves back into the container 10 . This is because, if less, the pump cap 20 does not move smoothly to the upper part, so it may not be quickly reused, which may be inconvenient.

In relation to the above, the injection unit 200 forms a first injection passage 210 that communicates with the connection passage 110 so that when the pump cap 20 is pressed, the liquid inside the container 10 is transferred to the outside. to be sprayed with

In detail, the injection unit 200 has a guide groove 220 formed in an annular shape to be located on the outside of the first injection passage 210 and a rear portion of the guide groove 220 formed on the front side. It is configured to include an opening/closing member 230 made of a flexible silicone material for opening and closing the first injection passage 210 by being internally inserted.

The guide groove 220 has a depth formed so that the rear of the opening and closing member 230 enters so that the opening and closing member 230 can close the first injection passage 210 , and the opening and closing member 230 has a rear surface. It is formed to protrude to, and may be configured to include an annular inner mouth protrusion (not shown) that can be fitted into the guide groove 220 .

That is, the opening and closing member 230 is coupled to the rear of the guide groove 220 so that the rear is in close contact with the front of the injection unit 200, and the front is in close contact with the rear of the connector 240 to be described in detail later. , closes the front of the first injection passage 210, is made of a silicone material, and is compressed forward by the pressure of the liquid to be sprayed when the pump cap 20 is pressed. ) to open the front so that the liquid can be injected through the injection nozzle 250 to be described in detail later.

In addition, the opening and closing member 230 is slightly pushed forward of the first injection passage 210 by the pressure of the moving liquid, so that the edge portion of the opening and closing member 230 and the moving hole ( 236) is formed and opened, thereby further increasing the moving speed of the liquid through the minute gap, thereby realizing the effect of being able to be smoothly sprayed through the injection nozzle 250.

Specifically, the opening and closing member 230 as described above protrudes at the center of the inner rear surface of the body 232 and the body 232 having an inner mouth protrusion formed at the rear, that is, the rear is inserted into and coupled to the guide groove 220 . Doedoe, a plurality of opening and closing protrusions 234 that are formed to have a smaller diameter toward the rear to close the first injection passage 210 and a plurality of holes formed through one side and positioned outside the opening and closing protrusions 234 It is configured to include a moving hole (236).

As described above, the body 232 has an inner mouth protrusion formed on the rear side so that the inner mouth protrusion is inserted into the guide groove 220, so that the rear surface is the front surface of the injection unit 200, that is, the first injection passage 210. Closes the front of the first injection passage 210 in close contact with the front.

At this time, when the rear surface of the body 232 is in close contact with the front surface of the first injection passage 210, the opening and closing protrusion 234 has By blocking the inlet that can enter, that is, the air flowing in the front of the first injection passage 210, the first injection passage 210 is sealed more stably and firmly, so that the pump cap 20 is pressed after the pressing operation. When moving upward, it blocks the inflow of external air.

In addition, when the pump cap 20 is pressed forward when the pump cap 20 is pressed, since the body 232 is made of a silicone material, it is compressed so that the thickness is reduced by the pressure of the liquid, and the first injection By opening the front of the flow path 210, the liquid is ejected.

In addition, the guide groove 220 is preferably formed to be longer than the length of the inner mouth projection of the opening and closing member 230, which is the front side when the pump cap 20 is raised after the pressing operation, that will be described in detail later. When compressed backward by the air introduced through the injection nozzle 250 and the connector 240, the opening and closing member 230 made of a silicone material can be compressed more smoothly, so that the first injection passage ( 210) to realize the effect of being able to close the front.

In connection with the above, it is preferable that the opening/closing protrusion 234 is formed to have a smaller diameter toward the rear, which is compressed forward by the liquid moving the body 232 when the pump cap 20 is pressed. This is to allow the liquid to more smoothly pass between the rear surface of the body 232 and the front surface of the first injection passage 210 .

That is, when the pump cap 20 is pressed, that is, when the opening and closing member 230 is pressed by the moving liquid, the rear surface of the body 232 and the first injection passage 210 are compressed. To pass between the front surfaces, the passed liquid passes through a plurality of moving holes 236 penetrating through the body 232 and moves to the connector 240 to be described in detail later, and passes through the connector 240 The liquid is sprayed to the outside by the spray nozzle 250 .

At this time, it will be apparent that the shape and number of the moving holes 236 can be variously changed and implemented according to the diameter of the first injection passage 210 . For smooth opening and closing, it is preferably formed in the shape of a long hole formed along the shape of the outer periphery.

On the other hand, the pump cap 20 is coupled to the rear so that the front of the injection unit 200 is inserted, the second injection passage 242 is formed, and the inner rear is in close contact with the front of the opening and closing member 230 . It is configured to include a connector 240 and a spray nozzle 250 coupled to the front of the connector 240 .

As described above, the connector 240 is in close contact with the front surface of the opening/closing member 230 so that the opening/closing member 230 can stably close the first injection passage 210 and the liquid that moves at the same time The opening/closing member 230 is supported so that it can be compressed forward, and the liquid passing through the opening/closing member 230 moves to the injection nozzle 250 coupled to the front through the second injection passage 242. make it possible

As the injection nozzle 250, any conventionally used nozzle may be used, so a detailed description thereof will be omitted.

In addition, the connector 240 is configured to include a moving groove (not shown) in the center of the inner rear surface, and the moving groove allows the liquid passing through the opening and closing member 230 to be diffused, so that the second The flow rate of the liquid moving to the injection passage 242 is increased so that it can be smoothly injected by the injection nozzle 250 .

In addition, the connector 240 is coupled to the front of the injection unit 200, the rear is inserted into the doedoe, rotatably coupled 90 degrees, the moving groove is a moving hole formed in the opening and closing member 230 on the inner rear surface ( 236) and may be configured to include a closing protrusion 244 formed to be longer than the length of the moving groove, the user rotates the connector 240 by 90 degrees to the closing protrusion 244 By closing the moving hole 236, the first injection passage 210 is closed, thereby preventing the liquid from being injected.

That is, when the user loses a protective cap (not shown) that can prevent the operation of the pump cap 20 when carrying the purified external air inflow type spray of the present invention, the liquid flows through the first injection passage 210 By preventing the opening and closing member 230 from passing through, it is possible to obtain the effect of easy portability. In this case, the protective cap is configured in a general fluid injection device to prevent the operation of the pump cap 20, and a detailed description thereof will be omitted.

In addition, the closing protrusion 244 is formed to have a longer length than the moving groove, so that the distal end is in close contact with the front surface of the opening and closing member 230, that is, the front surface of the body 232, so that the connector 240 is not freely rotated. This prevents the connector 240 from being rotated when the user needs it, and since the material of the opening and closing member 230 is made of silicon, it will be apparent that the connector 240 can be rotated.

In addition, the inlet groove 300 communicates with the connection flow path 110 so that the external air introduced through the inflow path 322 of the filter cap 320 to be described in detail later is purified by the filter 310 . to allow entry.

In detail, the inlet groove 300 is installed inside, and when it rises after the pressing operation of the pump cap 20, a filter 310 that filters the contaminants of the incoming external air, and the inside It is installed and installed to fix the filter 310 and includes a filter cap 320 in which an inflow passage 322 communicating with the inflow hole 114 is formed.

The filter 310 may use any filter capable of blocking conventionally known harmful substances or designated contaminants that may change the liquid stored inside the container 10, but the inlet groove 300 ), it is preferable to use a filter made of a paper material that can stably close the inlet hole 114 by being inside.

At this time, it is preferable that the filter 310 is made of hydrophobicity. This is because when the pump cap 20 is pressed, the liquid moves through the connection passage 110 of the connection part 100 through the inlet hole 114 . This is to block leakage into the inlet groove 300 .

The filter cap 320 is fitted inside the inlet groove 300 to fix the filter 310, thereby preventing liquid from leaking into the inlet hole 114, and the pump cap 20 is pressed. When rising after operation, the air introduced through the inflow passage 322 can be smoothly moved into the interior of the container 10 through the connection passage 110 and the tube 30 .

At this time, the inlet groove 300 is formed to protrude on the inner front surface, and is formed to protrude so as to be located on the outside of the inlet hole 114 and is configured to include a contact protrusion 330 that forms a contact groove 332, and the The filter cap 320 may be configured to include a pressing protrusion 324 that is protruded from the front surface and is inserted into the contact groove 332 .

The close contact protrusion 330 is bent so that the outside of the filter 310 installed inside is bent to enter the close contact groove 332 , so that the inlet hole 114 is more stably and firmly closed by the filter 310 . to achieve the desired effect.

When the filter cap 320 is slid and coupled to the inlet groove 300 , the pressing protrusion 324 presses the outside of the filter 310 installed inside the filter 310 so that the outside of the filter 310 is in the close contact groove. By bending into (332) to be inserted, the same effect as above is realized.

At this time, the filter 310 is formed larger than the diameter of the inlet groove 300 so that the outside of the filter 310 is bent and inserted into the adhesion groove 332 as described above so as to be more firmly attached to the inner front surface of the inlet groove 300 . Preferably, it is installed while being pressed by the filter cap 320 so that it can be smoothly inserted into the inlet groove 300 and installed.

As a result, the purified external air inflow type spray of the present invention uses the opening and closing member 230 to block the inflow of external air containing contaminants through the first injection passage 210 through which the liquid is moved to be sprayed. And, by allowing the external air purified by the filter 310 to flow into the inside of the container 10 through the inlet groove 300 , it is possible to minimize the deterioration of the liquid stored in the container 10 , so that for a long time A usable effect can be obtained.

The above has been described with reference to a preferred embodiment of the present invention, and is not limited to the above embodiment, and a person of ordinary skill in the art through the above embodiment does not deviate from the gist of the present invention It can be implemented with various changes in
