Detailed Description

The invention is further elucidated with reference to the drawing.

Referring to fig. 1, an embodiment of the present invention is a push type emulsion pump head, the structure of the pump head is that a body 1 and a housing 2 are separately designed, wherein the body 1 and the housing 2 are included, the body 1 is located inside the housing 2, as shown in fig. 2, a feed inlet 21 is provided at the lower part of the housing 2, more importantly, an air pressure cover 3 is installed at the upper part of the housing 2, the air pressure cover 3 is a key component for sealing the structure of the pump head, and is placed above the body 1, and a connecting tube 4 is installed on the air pressure cover 3, the connecting tube 4 is a hollow tubular structure, as shown in fig. 4, a first one-way switching valve 5 is further installed between the air pressure cover 3 and the body 1, the first one-way switching valve 5 can switch the direction seal into a one-way sealing valve by the movement of the connecting tube 4, and then the connecting tube 4 is communicated with the body 1 by the first one-way switching, correspondingly, the feed inlet 21 is also communicated with the body 1; as shown in fig. 3, a second one-way switching valve 6 is further installed at the lower part of the body 1, and the second one-way switching valve 6 and the first one-way switching valve 5 are sealed from top to bottom in the same one-way sealing direction and can enter from bottom to top; more importantly, as shown in fig. 5 and 6, a mutually matched annular inclined surface is additionally arranged on the side surface of the connecting pipe body 4 and the side surface of the air compression cover 3; referring to fig. 2 and 5, an air inlet 7 is additionally provided at one side of the housing 2, and the air inlet 7 is communicated with the inner cavity of the housing 2, and the inner cavity of the housing 2 is used for being communicated with the bottle body; and a sealing surface 31 corresponding to the air inlet 7 is additionally arranged on the side surface of the air pressure cover 3 and is used for sealing the air inlet 7 when the sealing surface 31 of the air pressure cover 3 is arranged at the position of the air inlet 7. The body 1 is a plastic cavity with a telescopic reset function, and according to the idea, the connecting pipe body 4, the first one-way switching valve 5, the air pressure cover 3 and the outer shell 2 can be made of plastic materials, and the plastic materials are stable in properties, so that the emulsion is not easily affected. When in use, the upper end of the connecting pipe body 4 is communicated with the discharge pipe, namely, emulsion is discharged through the bottle body, the inner cavity of the body 1, the connecting pipe body 4 and the discharge pipe; and the outer shell, the air pressure cover and the main body are completely closed spaces for assisting the main body to rebound through compressed air.

In this embodiment, through the structure of casing 2 and body 1 separation, make the inner chamber of casing 2 directly be linked together with the bottle, and under the one-way sealed effect of pneumatics lid 3, make body 1 extrude the emulsion at every turn after, the air all gets into the inside of bottle by inlet port 7 on the casing 2, and the air can't get into the bottle from connecting body 4 again under the effect of first one-way change-over valve 5, because inlet port 7 and casing 2 and bottle intercommunication's position certainly are above the liquid level, thereby can avoid producing the bubble in the bottle, be favorable to guaranteeing the use quality of emulsion, also can avoid getting into the air in the connecting body and influence the emulsion extrusion.

According to another embodiment of the present invention, in order to maintain the sealing between the lower portion of the housing 2 and the body 1, a circumferential inclined surface may be further provided at the inner bottom of the housing 2 and the lower end surface of the body 1. In order to ensure that the pump head is kept compact in structure under a normal state, as shown in fig. 3 to 5, the inventor optimally designs the fixing mode among the above components, specifically, a ring-shaped clamping groove 32 is arranged at the lower part of the air pressure cover 3, and then the upper part of the body 1 and the upper end part of the first one-way switching valve 5 are clamped in the ring-shaped clamping groove 32. Further, in order to facilitate the air in the casing 2 to be discharged, a check valve plate 8 may be additionally disposed between the outer side surface of the air pressure cover 3 and the casing 2, and the check valve plate 8 may allow only exhaust and no intake between the outer side surface of the first check switch valve 5 and the casing 2.

On the other hand, in order to realize the one-way sealing, in the present embodiment, the inventor adopts a structure including the valve body 61 and the elastic connecting strips 62 as the second one-way switching valve 6, and the number of the elastic connecting strips 62 is at least three and each of the elastic connecting strips is transversely arranged at the lower part of the body 1, so as to ensure the reliability of the one-way sealing of the body 1.

Referring to fig. 1 to 4, in practical use, the preferred embodiment of the present invention is that the body is mounted on the bottle body, and the feeding pipe communicated with the feeding port 21 is extended to a position below the liquid level of the emulsion; in the state shown in fig. 1, the connecting pipe body 4 is pressed down, and then the first one-way switching valve 5 is driven to move downwards to extrude the body 1, and simultaneously a gap is formed between the air pressure cover 3 and the shell 2, so that the state between the air pressure cover and the shell is changed from full sealing into one-way sealing; after the body 1 is extruded, air in the body firstly enters the bottle body through the feeding hole 21, then enters the shell 2 from the bottle body, and finally is discharged through a gap formed between the air pressure cover 3 and the shell 2;

when the connecting pipe body 4 is loosened, the body 1 is reset under the action of the self elastic force, negative pressure is formed in the body 1, emulsion in the bottle body is sucked into the body 1 from the feeding hole 21 through the feeding pipe, and the first one-way conversion valve 5 and the second one-way conversion valve 6 are sealed in a one-way mode from top to bottom, so that the emulsion in the bottle body can be sprayed out along with the connecting pipe body 4 after the connecting pipe body 4 is pressed for multiple times;

in the above process, each time the connection tube 4 is pressed, the sealing surface 31 on the side surface of the air pressure cap 31 unseals the air inlet hole 7 on the housing 2, and outside air enters the housing 2 from the air inlet hole 7, and enters the housing 2 from the bottle mouth through the inside of the housing for filling the air in the bottle to make up for the negative pressure, so that the emulsion in the bottle can be smoothly pressed out without affecting the air pressure in the bottle. In the process of pressing the connecting pipe body 4 for many times, the above mode is circulated in a reciprocating manner.
