[0002] Foam emulsion pumps, with their unique pump body structure, can extract liquid emulsions and transform them into foam, achieving not only efficient and quantitative emulsion output but also giving the foam a delicate and dense texture to meet different needs. However, traditional foam emulsion pumps usually directly mix air and liquid to achieve foam output. But this simple air-liquid mixing method cannot effectively handle the moisture in the air entering the pump body. Moist air mixed into the emulsion can easily cause the emulsion to deteriorate and dilute, shorten the product's shelf life, and affect its performance. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides a foam emulsion pump, which solves the technical problem that traditional foam emulsion pumps cannot handle moisture in the air, easily leading to humid air mixing into the emulsion, causing the emulsion to deteriorate and become diluted.
[0004] The purpose and effect of this foam emulsion pump are achieved by the following specific technical means:
[0005] A foam emulsion pump includes a pump head and a pump body for drawing liquid. The pump head includes a pusher and a connecting pipe is disposed inside the pusher. The pump body is disposed of a main pump core, which passes through the connecting pipe. A liquid outlet pipe is disposed on one side of the pusher. A liquid channel is formed through the pump body, the connecting pipe, and the liquid outlet pipe.
[0006] The top of the press head is provided with a detachable tooth cover. The tooth cover is ring-shaped and has a mesh on the top.

[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. This foam emulsion pump effectively solves the problem of traditional foam emulsion pumps being unable to handle moisture in the air, leading to emulsion deterioration and dilution, by incorporating absorbent cotton in the air intake chamber. The absorbent cotton consists of a first absorbent block and a second absorbent block, arranged in a stepped pattern. The first absorbent block is secured by a limiting ring at the top edge of the head, while the second absorbent block is secured by the mesh.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.
[0026] Example:
[0027] like Figures 1 to 5As shown, this utility model provides a foam emulsion pump, including a pump head and a pump body 11 for drawing liquid. The pump head includes a pusher 21, inside which is a connecting pipe 22. To ensure continuous emulsion delivery, the pusher 21 is hollow and permeable. The pump body 11 contains a main pump core 12, which passes through the connecting pipe 22. When the pusher 21 is pressed, the main pump core 12 moves within the pump body 11, drawing the emulsion out of the pump body 11 and delivering it through the connecting pipe 22. A liquid outlet pipe 23 is provided on one side of the pusher 21. The pump body 11, connecting pipe 22, and liquid outlet pipe 23 cooperate to form a complete liquid channel, allowing the emulsion to be smoothly output. A removable toothed cap 31 is installed on the top of the pusher 21. The toothed cap 31 is annular and fixed around the top edge of the pusher 21. A mesh 32 is provided on the top of the cap 31, and the pusher 21, cap 31, and mesh 32 together form an air inlet chamber. An air inlet hole 24 is provided on the pusher 21, and the liquid channel communicates with the air inlet chamber through the air inlet hole 24. To prevent humid air from affecting the emulsion quality, absorbent cotton 33 is provided inside the air inlet chamber. A mounting cap is provided on the pump body 11, which allows for a detachable connection between the pump body 11 and the emulsion bottle, facilitating later cleaning or replacement of the pump body 11; at the same time, different mounting cap sizes can be used to accommodate different types of emulsion bottles.
[0028] The network communication device 32 has multiple sets of air intake slots 34. These air intake slots 34 are polygonal and arranged in a regular pattern on the surface of the network communication device 32. The numerous air intake slots 34 combine with each other to form a honeycomb structure. With the help of this honeycomb structure, the air intake chamber is smoothly connected to the outside world through the air intake slots 34, and outside air can enter the air intake chamber in an orderly manner through the air intake slots 34.
[0029] The absorbent cotton 33 consists of a first absorbent block and a second absorbent block, arranged in a stepped configuration. A limiting ring 35 is provided at the top edge of the push-button 21, and the first absorbent block is precisely positioned within the limiting ring 35. The second absorbent block is positioned within the mesh 32, serving to block and absorb moisture within the air intake chamber. When outside air enters the air intake chamber through the air intake groove 34, the absorbent cotton 33 effectively absorbs moisture from the air, preventing humid air from contacting the emulsion and ensuring that the emulsion pump can continuously and stably output high-quality emulsion.
[0030] A bent tube 36 is installed on one side of the nozzle 21. One end of the bent tube 36 is the liquid inlet, and the other end is the liquid outlet. The liquid inlet is fitted onto the liquid outlet tube 23 with a diameter that matches the tube diameter, allowing the liquid outlet tube 23 and the bent tube 36 to communicate internally, so that the emulsion can flow smoothly from the liquid outlet tube 23 into the bent tube 36. A nozzle 37 is fitted onto the liquid outlet of the bent tube 36, and a diffuser 38 is provided inside the nozzle 37. When the emulsion flows through the nozzle 37, the diffuser 38 disperses the emulsion, allowing it to be sprayed out in a more uniform manner.
[0031] like Figure 2 , Figure 3 , Figure 5 As shown, the mounting cover consists of a first cover body 41 and a second cover body 42. On one side of the first cover body 41, there are multiple sets of limiting grooves 43. The second cover body 42 is provided with a limiting strip 44 at the corresponding position. When the second cover body 42 is installed onto the first cover body 41, the limiting strip 44 can be inserted into the limiting groove 43, which plays a role in initial positioning. In addition, the first cover body 41 and the second cover body 42 are provided with interlocking threads inside. Rotating the two can achieve connection, thereby installing the emulsion pump onto the emulsion bottle.
[0032] The second cover 42 has mounting blocks 45 on both sides, each with a positioning hole 46. A positioning bead 47 is placed at the open end of the positioning hole 46, and a spring is installed inside the positioning hole 46. One end of the spring abuts against the second cover 42, and the other end pushes against the positioning bead 47. In its natural state, the positioning bead 47 is partially exposed outside the positioning hole 46. Meanwhile, the first cover 41 has positioning plates 48 on both sides, each with a positioning through hole 49. When the first cover 41 and the second cover 42 are assembled, the positioning bead 47 passes through the positioning through hole 49 under the spring force. This design provides an extra layer of positioning protection during the connection of the first cover 41 and the second cover 42, making the installation process more convenient and reducing assembly difficulty. It also improves the stability of the connection to a certain extent, effectively preventing the cover from becoming loose due to shaking during use.
[0033] The specific usage and function of this embodiment are as follows:
[0034] During use, outside air enters the air intake chamber through the honeycomb-structured air intake groove 34 on the mesh 32 during emulsion delivery. The air intake chamber is enclosed by the push-button 21, the tooth cover 31, and the mesh 32. Moisture in the air is absorbed by the water-absorbing cotton 33 arranged in a stepped pattern inside the air intake chamber. Then, the air mixes with the emulsion in the emulsion channel through the air intake hole 24 on the push-button 21.
[0035] The mixed emulsion enters the curved pipe 36, with the inlet of the curved pipe 36 fitted onto the outlet pipe 23 to ensure smooth emulsion flow. The emulsion flows out from the outlet of the curved pipe 36 and is sprayed out through the nozzle 37 fitted onto the outlet. During this process, the diffuser 38 inside the nozzle 37 disperses the emulsion, causing it to be sprayed out evenly in the form of foam.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
