[0032] This utility model proposes a miniature soap dispenser pump 10.

[0033] Please see Figures 1 to 3 In one embodiment of this utility model, the miniature soap dispenser pump 10 includes a pump body 100, a valve seat 200, and a valve cover 300. The pump body 100 has a first compression chamber 110. The valve seat 200 is disposed on one side of the pump body 100, and the valve seat 200 and the valve cover 300 together form a separated inlet chamber 410 and a mixing chamber 420, which is provided with an inlet 210. The valve cover 300 is disposed on the side of the valve seat 200 away from the pump body 100, and the valve cover 300 is provided with an outlet 3. 10. The inlet chamber 410 is connected to the inlet port 210, the mixing chamber 420 is connected to the outlet port 310, and the first compression chamber 110 is connected to both the inlet chamber 410 and the mixing chamber 420. The first compression chamber 110 can transfer the liquid in the inlet chamber 410 to the mixing chamber 420. The valve seat 200 is provided with a first positioning part 220 on one side facing the valve cover 300, and the valve cover 300 is provided with a second positioning part 320 that is adapted to the first positioning part 220.

[0034] Specifically, the pump body 100 has a first compression chamber 110 for compressing liquid to achieve the liquid pumping function. A valve seat 200 is located on one side of the pump body 100, and has an inlet 210 for introducing liquid, which can be soap solution, water, detergent, or other fluid media, thus diversifying the application scenarios of the miniature soap solution pump 10. A valve cover 300 is located on the side of the valve seat 200 away from the pump body 100, and has an outlet 310 for discharging the pumped liquid. The outlet 310 can be located on the upper surface of the valve cover 300 or on the side wall of the valve cover 300.

[0035] The valve cover 300 and valve seat 200 enclose a separate inlet chamber 410 and a mixing chamber 420. The inlet chamber 410 communicates with the inlet port 210 on the valve seat 200 and is used to receive liquid entering from the inlet port 210. When liquid is drawn in, the first compression chamber 110 changes from a contracted state to an expanded state to draw the liquid in the inlet chamber 410 into the first compression chamber 110; the first compression chamber 110 then changes from an expanded state to a contracted state to push the liquid into the mixing chamber 420. The mixing chamber 420 communicates with the outlet port 310 on the valve cover 300 and is used to store the liquid transferred from the first compression chamber 110 after being compressed by the pump body 100, and finally discharge it through the outlet port 310.

[0036] The first positioning part 220 on the valve seat 200 and the second positioning part 320 on the valve cover 300 are mutually adapted. During the assembly process of the valve cover 300 and the valve seat 200, the first positioning part 220 and the second positioning part 320 can quickly and accurately align, ensuring that the valve cover 300 and the valve seat 200 can be accurately aligned. This reduces the assembly difficulty of the valve cover 300 and the valve seat 200, improves the assembly efficiency of the valve cover 300 and the valve seat 200, and thus improves the production efficiency and product yield of the micro soap liquid pump 10.

[0037] The technical solution of this utility model achieves precise positioning of the valve cover 300 and the valve seat 200 by providing a first positioning part 220 on one side of the valve seat 200 facing the valve cover 300 and a corresponding matching second positioning part 320 on the valve cover 300. During the assembly process, the valve seat 200 and the valve cover 300 can be docked quickly and accurately, thereby improving the assembly efficiency and product yield of the valve cover 300 and the valve seat 200.

[0038] In one implementation, please refer to Figure 2 and Figure 3 The first positioning part 220 is configured as a positioning protrusion, and the second positioning part 320 is configured as a positioning hole.

[0039] The positioning protrusion can quickly and directly establish a connection with the positioning hole, ensuring that the valve cover 300 and the valve seat 200 can be accurately aligned, enabling rapid assembly of the valve cover 300 and the valve seat 200. The positioning protrusion can be columnar, and correspondingly, the positioning hole can be a blind hole formed on the inner wall surface of the valve cover 300; or the inner wall surface of the valve cover 300 can be formed with a positioning post, which has a positioning hole that matches the positioning protrusion.

[0040] In another embodiment, the first positioning part 220 is configured as a positioning hole, and the second positioning part 320 is configured as a positioning protrusion.

[0041] In other embodiments, the first positioning part 220 and the second positioning part 320 may also be magnetically engaged. The first positioning part 220 may also be a rib with a certain shape, such as the rib extending in a straight line or curve on the surface of the valve seat 200, or the rib being a triangle or other polygon, or the rib being other irregular shapes, and the positioning hole is set as a groove that matches the rib.

[0042] In one implementation, please refer to Figure 2 and Figure 5 At least three first positioning parts 220 are provided. The distance from at least one first positioning part 220 to one of its adjacent first positioning parts 220 is L1, and the distance to another of its adjacent first positioning parts 220 is L2, where L1 > L2.

[0043] At least the distances between the first positioning part 220 and its two adjacent first positioning parts 220 are different. This non-uniform distribution of the first positioning parts 220 can serve as a mistake-proofing mechanism to prevent incorrect assembly. Understandably, when the valve cover 300 and valve seat 200 are misaligned during assembly, the other first positioning parts 220 cannot be properly aligned. Operators can immediately detect and correct the error, avoiding poor sealing or functional failure due to incorrect assembly. Simultaneously, it can significantly reduce the scrap rate caused by assembly errors, thereby reducing production costs.

[0044] In one implementation, please refer to Figure 2 The first positioning part 220 is provided in four parts, and the connecting line of the four first positioning parts 220 forms a quadrilateral. The quadrilateral can be a rectangle, a trapezoid, or a rhombus other than a square.

[0045] In another implementation, please refer to Figure 5 The first positioning part 220 is provided in three parts, and the connecting line of the three first positioning parts 220 forms a triangle. The triangle can be a scalene triangle or an isosceles triangle.

[0046] In one implementation, please refer to Figures 4 to 6An air inlet chamber 430 is formed between the valve seat 200 and the valve cover 300. The valve cover 300 is provided with an air inlet 330 that communicates with the air inlet chamber 430. The pump body 100 is also provided with a second compression chamber 120 that communicates with the air inlet chamber 430 and the mixing chamber 420. The second compression chamber 120 can transfer the gas in the air inlet chamber 430 to the mixing chamber 420. The liquid outlet 310 is provided with a foam generator to generate foam from the mixture in the liquid outlet 310.

[0047] The pump body 100 also has a second compression chamber 120, which is used to compress air to achieve the gas pumping function. The valve cover 300 is provided with a liquid outlet 310 and an air inlet 330. The valve cover 300 and the valve seat 200 enclose and form a mutually separated liquid inlet chamber 410, air inlet chamber 430, and mixing chamber 420. The air inlet chamber 430 communicates with the air inlet 330 on the valve cover 300 to introduce air. When air is drawn in, the second compression chamber 120 changes from a contracted state to an expanded state to draw air from the air inlet chamber 430 into the second compression chamber 120; the second compression chamber 120 then changes from an expanded state to a contracted state to push the air into the mixing chamber 420, so that the air and liquid undergo preliminary mixing in the mixing chamber 420 to form a gas-liquid mixture. Finally, the gas-liquid mixture is delivered from the liquid outlet 310, completing one full pumping process. The liquid outlet 310 is equipped with a foam generator. When the gas-liquid mixture in the mixing chamber 420 passes through the liquid outlet 310, it can generate fine foam, which improves the cleaning effect and user experience.

[0048] Understandably, please refer to Figure 1 When the valve cover 300 and valve seat 200 enclose a separated inlet chamber 410 and mixing chamber 420, liquid soap solution is discharged from the outlet 310. The miniature soap solution pump 10 can be used as an outlet pump. Please refer to [link / reference]. Figure 4 When the valve cover 300 and the valve seat 200 enclose and form a separated liquid inlet chamber 410, air inlet chamber 430 and mixing chamber 420, the soap solution is delivered from the liquid outlet 310 in a foamy state. The micro soap solution pump 10 can be used as a foam pump, thereby increasing the application scenarios of the micro soap solution pump 10.

[0049] In one implementation, please refer to Figure 4 and Figure 6 The foam generator includes a support net 510 and a foaming net 520. The inner wall of the outlet 310 and the support net 510 together define an installation space, and the foaming net 520 is located within the installation space.

[0050] The support net 510 provides support for the foaming net 520, ensuring its stable installation at the outlet 310. Simultaneously, the mesh structure of the support net 510 allows the gas-liquid mixture in the mixing chamber 420 to pass smoothly. Compared to traditional mounting brackets for the foaming net 520, the support net 510 is significantly thinner, greatly reducing the overall height and volume of the foam generator, thereby reducing the height and volume of the micro soap pump 10 and lowering its production cost. The foaming net 520, through its porous structure, thoroughly mixes the gas-liquid mixture to generate fine foam. The foaming net 520 is confined within the installation space defined by the inner wall of the outlet 310 and the support net 510, ensuring it does not detach from the outlet 310. Furthermore, the foaming net 520 can also be bonded to the support net 510 and / or the inner wall of the outlet 310.

[0051] In one embodiment, the mesh count of the foaming net 520 is not less than 200 mesh.

[0052] The higher the mesh count of the 520 foaming mesh, the smaller the pore size, resulting in better mixing of the gas-liquid mixture and finer foam. A mesh count of at least 200 mesh ensures more uniform gas-liquid integration and finer foam. The 520 foaming mesh can be a single layer or multiple layers; multiple layers further improve the fineness and stability of the foam. The 520 foaming mesh can be mesh-like or openwork. It can be made of materials such as stainless steel, nylon, or polypropylene.

[0053] In one implementation, please refer to Figure 5 and Figure 6 The volume of the air inlet chamber 430 is greater than the volume of the liquid inlet chamber 410, and the number of second compression chambers 120 is greater than the number of first compression chambers 110.

[0054] By increasing the volume of the air intake chamber 430 and the number of second compression chambers 120, the amount of air entering the mixing chamber 420 is greater than the amount of soap solution, thereby improving the fineness and stability of the foam. More air generates more and smaller bubbles, resulting in finer foam. Finer foam provides better cleaning performance and a better user experience, enhancing the product's market competitiveness. More air also improves foam stability, preventing it from breaking down too quickly. Stable foam can last longer, improving cleaning effectiveness.

[0055] In other embodiments, the volume of the air inlet chamber 430 is approximately the same as the volume of the liquid inlet chamber 410, and the number of the second compression chambers 120 is the same as the number of the first compression chambers 110.

[0056] In one implementation, please refer to Figures 1 to 5The valve seat 200 is provided with a plurality of connecting holes 230, some of which connect to the first compression chamber 110 and the mixing chamber 420, and some of which connect to the second compression chamber 120 and the mixing chamber 420. The micro soap pump 10 also includes a valve umbrella 600, which is located on the side of the valve seat 200 facing the valve cover 300 and covers the plurality of connecting holes 230 so that the first compression chamber 110 and the second compression chamber 120 are connected to or blocked from the mixing chamber 420, respectively.

[0057] When the first compression chamber 110 is in a compressed state, the greater pressure can open the valve umbrella 600, allowing the first compression chamber 110 to communicate with the mixing chamber 420. Liquid in the first compression chamber 110 can then enter the mixing chamber 420 through the corresponding connecting hole 230. When the second compression chamber 120 is in a compressed state, the greater pressure can open the valve umbrella 600, allowing the second compression chamber 120 to communicate with the mixing chamber 420. Air in the second compression chamber 120 can then enter the mixing chamber 420 through the corresponding connecting hole 230. When the first compression chamber 110 and the second compression chamber 120 are in an expanded state, a greater suction force can hold the valve umbrella 600 in place, tightly covering the connecting hole 230, thus isolating the first and second compression chambers 110 and 120 from the mixing chamber 420. The valve umbrella 600 acts as a one-way valve, effectively preventing the gas-liquid mixture in the mixing chamber 420 from flowing back into the first compression chamber 110 or the second compression chamber 120.

[0058] In one implementation, please refer to Figure 4 and Figure 6 The valve umbrella 600 has multiple limiting ribs 610 on the side facing the valve cover 300, and the valve cover 300 has multiple limiting parts 340 on the side facing the valve seat 200. The multiple limiting parts 340 are spaced apart along the circumference of the liquid outlet 310 and abut against the limiting ribs 610. The multiple connecting holes 230 are located on the outer periphery of the multiple limiting parts 340.

[0059] The limiting part 340 abuts against the limiting rib 610, which can prevent the valve umbrella 600 from detaching from the valve seat 200 under the strong impact force of liquid or air, thus preventing the valve umbrella 600 from failing. Multiple limiting parts 340 are spaced apart circumferentially along the outlet 310. This ensures that the valve umbrella 600 is subjected to uniform force, guaranteeing effective contact of the limiting parts 340; it also facilitates the flow of the gas-liquid mixture in the mixing chamber 420 from the gaps between adjacent limiting parts 340 to the outlet 310. The connecting hole 230 is located on the outer periphery of the multiple limiting parts 340, preventing the limiting parts 340 from affecting the opening and closing of the connecting hole 230, ensuring that the liquid in the first compression chamber 110 and the air in the second compression chamber 120 can smoothly enter the mixing chamber 420.

[0060] In one implementation, please refer to Figure 1 and Figure 4The miniature soap pump 10 also includes an inlet nozzle 700, which is located on the side of the valve seat 200 away from the valve cover 300, corresponding to the inlet port 210.

[0061] The air inlet 330 and liquid outlet 310 are located on the side of the valve cover 300 away from the valve seat 200, while the liquid inlet 700 and liquid outlet 210 are located on the side of the valve seat 200 away from the valve cover 300. The different locations of the liquid inlet 210 and air inlet 330 optimize the internal flow channel design, reduce fluid resistance during transmission, and improve pumping efficiency. When the miniature soap dispenser pump 10 is installed in a soap dispenser bottle, the downward-facing liquid inlet 700 is more compatible with the bottle. Simultaneously, the different locations of the air inlet 330 and liquid outlet 210 prevent the soap dispenser bottle or other structures that mate with the liquid inlet 700 from obstructing the air inlet 330, thus affecting the air intake effect.

[0062] In other embodiments, the inlet nozzle 700 and the inlet port 210 may also be located on the side of the valve seat 200 near the valve cover 300, or on the periphery of the valve seat 200.

[0063] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
