Description

Technical Field

[0001] The utility model relates to the technical field of emulsion head cap manufacturing, and specifically relates to an emulsion head cap structure. Background Art

[0002] In daily life, people often use pump-pressurized liquid storage containers, such as hand sanitizer bottles, emulsion bottles, essence bottles, etc. Their working principles are similar. They all increase the pressure inside the container by pressing the pump head, so as to pump the liquid (or emulsion) in the container out of the container.

[0003] For example, the spray bottle with the application number CN201820884522.6 and the name "A Spray Bottle" discloses a spray bottle: a bottle body, an outer cover buckled on the bottle body, a pump body outer cover accommodated in the outer cover. The pump body outer cover includes a conduit extending along its axis direction. The pump body outer cover is sequentially provided with a first liquid outlet, a second liquid outlet and a third liquid outlet connected to each other in the radial direction from the center outwards. The first liquid outlet is connected to the conduit. The diameter of the first liquid outlet is smaller than that of the second liquid outlet. The diameter of the third liquid outlet is smaller than that of the first liquid outlet. A pump body arranged in the bottle body can supply the liquid in the bottle body to the conduit. The pump body has a valve rod that can move up and down to control the connection or isolation between the conduit and the liquid inlet of the pump body. However, like most pump-pressurized containers, this spray bottle has the defect of not having a back suction function. After each liquid storage, there will be liquid residues in the pump head, and these liquids will flow out under the residual pressure in the container, resulting in waste. Therefore, its structure needs to be further improved. Summary of the Utility Model

[0004] The purpose of the utility model is to make up for the above deficiencies and disclose to the society an emulsion head cap structure with reasonable structure, convenient use and a back suction function.

[0005] The technical solution of the utility model is realized as follows:

[0006] An emulsion head cap structure includes an emulsion head cap body. The emulsion head cap body includes a head cap base fixedly sealed with a solution bottle. A middle seat is assembled in the head cap base. A liquid inlet hole is arranged on the middle seat. A sealing gasket is arranged at the liquid inlet hole. An elastically pressable pressing head is assembled on the head cap base. A liquid outlet hole is arranged on the pressing head. A recovery component is arranged between the middle seat and the pressing head. The recovery component includes an outer pipe fitting, a middle pipe fitting and an inner pipe fitting. A first sealing member is arranged between the outer pipe fitting and the middle pipe fitting. A first spring is arranged between the outer pipe fitting and the first sealing member. A back suction cavity is formed among the outer pipe fitting, the middle pipe fitting and the first sealing member. A back suction hole is arranged on the outer pipe fitting.

[0007] Measures to further optimize this technical solution are as follows:

[0008] As an improvement, the specific structure in which the pressing head can be elastically pressed is as follows: An intermediate seat is fixed to the upper end of the middle seat. A second spring is provided between the inner pipe fitting and the intermediate seat, and the lower part of the inner pipe fitting passes through the intermediate seat.

[0009] As an improvement, a central pipe is fixed to the lower part of the inner pipe fitting. A second seal is provided between the inner pipe fitting and the middle seat, and the central pipe passes through the second seal.

[0010] As an improvement, an upper connecting part is provided at the upper part of the middle pipe fitting, and the outer pipe fitting is connected and fixed to the upper connecting part; a lower connecting part is provided at the lower part of the middle pipe fitting, and the inner pipe fitting is connected and fixed to the lower connecting part.

[0011] As an improvement, a limiting rib adapted to the sealing gasket is provided on the middle seat.

[0012] As an improvement, the sealing gasket includes an outer ring of the sealing gasket and a sealing head, and a connecting strip is provided between the outer ring of the sealing gasket and the sealing head.

[0013] As an improvement, a retaining ring is formed on the outer periphery of the upper part of the pressing head. The setting of the retaining ring can prevent the residual liquid from flowing out and improve the back suction effect.

[0014] As an improvement, first connecting heads and second connecting heads are respectively formed at both ends of the connecting strip. The first connecting head is connected to the sealing head, the second connecting head is connected to the outer ring of the sealing gasket, and the included angle between the diameter line where the first connecting head is located and the diameter line where the second connecting head is located is 60° to 100°.

[0015] As an improvement, the sealing gasket is an integrally formed integral structure.

[0016] As an improvement, an outer cover is equipped outside the emulsion head cap body on the solution bottle. The setting of the outer cover can protect the internal emulsion head cap and avoid contamination of the emulsion head cap when not in use.

[0017] The advantages of this utility model compared with the prior art are as follows:

[0018] A lotion head cap structure of the present utility model has a reasonable structure. By arranging a recovery component inside the lotion head cap to form a suction cavity, when the pressing head is pressed down, the space of the suction cavity is compressed. When the pressing head resets, the space of the suction cavity increases to form a negative pressure, thereby sucking the residual liquid on the pressing head into the suction cavity. When the pressing head is pressed down next time, the space of the suction cavity decreases, and the liquid in the suction cavity is discharged. Through the design of the recovery structure, the lotion head cap of the present utility model has a suction function and can avoid waste. Description of the Drawings

[0031] As Figures 1 to 6 shown, an emulsion head cap structure includes an emulsion head cap body. The emulsion head cap body includes a head cap base 2 that is hermetically fixed to a solution bottle 1. A middle seat 3 is assembled in the head cap base 2. A liquid inlet hole is provided on the middle seat 3, and a sealing gasket 4 is provided at the liquid inlet hole. A press head 5 that can be elastically pressed is assembled on the head cap base 2, and a liquid outlet hole 5a is provided on the press head 5. A recovery assembly is provided between the middle seat 3 and the press head 5. The recovery assembly includes an outer pipe fitting 61, a middle pipe fitting 62, and an inner pipe fitting 63. A first seal 64 is provided between the outer pipe fitting 61 and the middle pipe fitting 62. A first spring 65 is provided between the outer pipe fitting 61 and the first seal 64. A suction cavity 6a is formed among the outer pipe fitting 61, the middle pipe fitting 62, and the first seal 64, and a suction hole 61a is provided on the outer pipe fitting 61.

[0032] The specific structure of the press head 5 that can be elastically pressed is as follows: An intermediate seat 7 is fixed to the upper end of the middle seat 3. A second spring 71 is provided between the inner pipe fitting 63 and the intermediate seat 7, and the lower part of the inner pipe fitting 63 passes through the intermediate seat 7.

[0033] A central tube 8 is fixed to the lower part of the inner pipe fitting 63. A second seal 9 is provided between the inner pipe fitting 63 and the middle seat 3, and the central tube 8 passes through the second seal 9.

[0034] An upper connecting portion 62a is provided at the upper part of the middle pipe fitting 62, and the outer pipe fitting 61 is fixedly connected to the upper connecting portion 62a; a lower connecting portion 62b is provided at the lower part of the middle pipe fitting 62, and the inner pipe fitting 63 is fixedly connected to the lower connecting portion 62b.

[0035] A retaining ring 51 is formed on the outer periphery of the upper part of the pressing head 5. The arrangement of the retaining ring 51 can prevent the residual liquid from flowing out and improve the back suction effect.

[0036] A limiting rib 31 adapted to the sealing gasket 4 is provided on the middle seat 3. The limiting rib 31 can limit the displacement of the sealing gasket 4.

[0037] The sealing gasket 4 includes a sealing gasket outer ring 41 and a sealing head 42, and a connecting strip 43 is provided between the sealing gasket outer ring 41 and the sealing head 42.

[0038] Both ends of the connecting strip 43 are respectively formed with a first connecting head 43a and a second connecting head 43b. The first connecting head 43a is connected to the sealing head 42, the second connecting head 43b is connected to the sealing gasket outer ring 41, and the included angle between the diameter line where the first connecting head 43a is located and the diameter line where the second connecting head 43b is located is 60° to 100°. With such a structural design, the positions of the first connecting head 43a and the second connecting head 43b are staggered by a certain angle (to avoid being on the same diameter line), so that the deformation amount between the sealing head 42 and the sealing gasket outer ring 41 can be increased, and the liquid output can be increased.

[0039] The sealing gasket 4 is an integrally formed integral structure.

[0040] An outer cover 11 is equipped outside the emulsion head cap body on the solution bottle 1. The setting of the outer cover 11 can provide protection for the internal emulsion head cap and can also avoid contamination of the emulsion head cap when not in use.

[0041] Working principle:

[0042] As Figure 2 shown, when the pressing head 5 is not pressed, both the first spring 65 and the second spring 71 are in the natural assembly state, and at this time, the space in the back suction chamber 6a is relatively large.

[0043] As Figure 5 shown, when the pressing head 5 is pressed, the second spring 71 is compressed, and the pressing head 5 drives the outer pipe fitting 61, the middle pipe fitting 62, the inner pipe fitting 63, and the central pipe 8 to move downward as a whole against the elastic force of the second spring 71 until the lower end of the central pipe 8 abuts against the sealing gasket 4. At the same time, the first spring 65 is compressed, and the space in the back suction chamber 6a is compressed and reduced.

[0044] At this time, release the pressing head 5. The pressing head 5 is reset upward under the elastic force of the second spring 71. The space between the lower end of the central tube 8 and the sealing gasket 4 increases to form a negative pressure. A pressure difference is formed between the internal space of the solution bottle 1 and the inside of the emulsion head cap. The sealing head 42 of the sealing gasket 4 is pushed open, so that the liquid inlet hole is opened. A liquid outlet channel is formed between the liquid inlet hole and the liquid outlet hole 5a. The liquid in the solution bottle 1 is pumped out from the liquid outlet hole 5a through the liquid outlet channel. The above is the working principle of liquid outlet, which is the same as that of the existing emulsion bottle.

[0045] The emulsion head cap structure of the present utility model has a back suction function. When the pressing head 5 is reset, under the elastic force of the first spring 65, the distance between the upper part of the outer pipe fitting 61 and the first sealing member 64 increases, and the space in the back suction cavity 6a increases to form a negative pressure. The residual liquid on the pressing head 5 will be sucked into the back suction cavity 6a. A retaining ring 51 is formed on the outer periphery of the upper part of the pressing head 5.

[0046] When the pressing head 5 is pressed down next time, the space in the back suction cavity 6a decreases. While the liquid is normally discharged, the liquid originally sucked into the back suction cavity 6a is also discharged at the same time, creating space for the next back suction.

[0047] The above are only the preferred embodiments of the present utility model, and do not limit the implementation manners and protection scope of the present utility model. For those skilled in the art, it should be realized that all the equivalent replacements and obvious changes made by using the description and illustrations of the present utility model should be included in the protection scope of the present utility model.
