Description

Technical Field

[0001] This utility model is an easy-to-clean press pump head, belonging to the field of emulsion pump technology. Background Technology

[0002] Pump heads, as core components in the packaging of liquid products such as emulsions and detergents, are widely used in the daily chemical, medical, and industrial fields. Traditional push-button pump heads typically consist of a pump body, piston assembly, suction tube, and dispensing nozzle. Their working principle relies on the negative pressure difference generated by the pressing operation to achieve liquid extraction and dispensing.

[0003] After traditional pump heads complete liquid extrusion, liquid media can easily remain in their internal flow channels and piston chambers, especially in the application of high-viscosity emulsion products. Users usually disassemble the pump head to rinse or soak it for cleaning, but there is a significant drawback: existing pump heads cannot be cleaned immediately without disassembly. The residue can easily breed bacteria or oxidize and deteriorate, causing contamination of newly injected liquid during secondary use. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a press pump head that is easy to clean, in order to solve the problem that liquid media easily remains in the internal flow channels and piston chambers of traditional pump heads after liquid extrusion, especially in the case of high-viscosity emulsion products. Users usually disassemble the pump head to rinse or soak it for cleaning, but there are significant drawbacks. Existing pump heads cannot be cleaned immediately without disassembly, and the residue is prone to bacterial growth or oxidation and deterioration, which leads to contamination of newly injected liquid during secondary use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a push-button pump head that is easy to clean, comprising:

[0006] The pump head body includes a pump head lock cover and a pump chamber. The pump head lock cover is hollow and located at the top of the pump chamber. The top of the pump chamber is provided with a pump head main column extending out of the hollow opening of the pump head lock cover.

[0007] The pressing head is located on the top of the pump head body. The top of the pressing head is provided with a sliding through hole and a positioning groove. The outer wall of the pressing head is provided with a liquid outlet pipe.

[0008] A blocking and cleaning component is disposed within a pressing head. The blocking and cleaning component includes a fixed plate, a blocking plate, a cleaning chamber, and a sealing cover. The blocking plate is spaced above the fixed plate. The fixed plate has a first liquid outlet and several reset grooves. The bottom of the blocking plate has several connecting rods, which are movably embedded in the reset grooves. A reset spring is provided between the connecting rods and the bottom surface of the reset groove. The cleaning chamber is located on top of the blocking plate. The top and side walls of the cleaning chamber have inlets and outlets, respectively. The outer wall of the top of the cleaning chamber has a deformation groove, and the hinge in the deformation groove has an elastic buckle. The sealing cover is embedded in the inlet.

[0009] Furthermore, the shape of the pump head main column opening is adapted to the shape of the first liquid outlet to ensure smooth pumping of liquid.

[0010] Furthermore, the top surface of the pump head main column is in contact with the bottom surface of the fixing plate, effectively preventing liquid from leaking into the gaps.

[0011] Furthermore, the inner wall of the pressing head is provided with a limiting annular plate, and the blocking plate moves vertically along the inner wall of the pressing head and is located above the blocking plate. The bottom surface of the limiting annular plate abuts against the top surface of the blocking plate, effectively limiting the blocking plate to a preset height.

[0012] Furthermore, the sliding through hole and the alignment groove are coaxially arranged to ensure the precise alignment and stable connection between the faucet outlet and the push head 2.

[0013] Furthermore, the bottom of the positioning groove has a closed end face and its radial dimension is larger than the diameter of the sliding through hole, which facilitates the use of the faucet outlet shape.

[0014] Furthermore, the inner wall of the reset groove is provided with a first limiting block, and the outer wall of the connecting rod is provided with a second limiting block that cooperates with the first limiting block, effectively preventing the connecting rod 321 from sliding and falling off in the reset groove 312.

[0015] Furthermore, the connection method between the pressing head and the pump head main column is either an embedded connection or a threaded connection, which can adapt to the sealing requirements of the connection between the pressing head and the pump head main column in different scenarios.

[0016] Furthermore, the pressing head and the pump head main column are specifically embedded to achieve quick assembly and axial positioning.

[0017] Furthermore, the pressing head and the pump head main column are specifically connected by threads, which further improves the sealing effect.

[0018] The beneficial effects of this utility model are: it allows for immediate cleaning without disassembling the pump head, breaking through the traditional cleaning methods that require disassembly, rinsing, or soaking. It is convenient and efficient, saving users time and effort, and effectively reduces liquid residue in the internal flow channels and piston chamber after extrusion. This is especially beneficial for high-viscosity emulsion products, greatly improving the situation of severe residue buildup in traditional pump heads. Reduced residue prevents bacterial growth and oxidation, ensuring product hygiene and preventing contamination of newly injected liquid during secondary use, thus enhancing user experience and product safety.

Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] Example 1

[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a technical solution for an easy-to-clean press pump head, comprising:

[0031] Pump head body 1, the pump head body 1 includes pump head lock cover 11 and pump chamber 12, the pump head lock cover 11 is hollow and located on the top of the pump chamber 12, and the top of the pump chamber 12 is provided with a pump head main column 13 extending out of the hollow opening of the pump head lock cover 11;

[0032] Press head 2, the press head 2 is located on the top of the pump head body 1, the top of the press head 2 is provided with a sliding through hole 21 and a positioning groove 22, and the outer wall of the press head 2 is provided with a liquid outlet pipe 23;

[0033] A blocking cleaning component 3 is disposed inside the pressing head 2. The blocking cleaning component 3 includes a fixed plate 31, a blocking plate 32, a cleaning chamber 33, and a sealing cover 34. The blocking plate 32 is spaced above the fixed plate 31. The fixed plate 31 is provided with a first liquid outlet 311 and several reset grooves 312. The bottom of the blocking plate 32 is provided with several connecting rods 321. The connecting rods 321 are movably embedded in the reset grooves 312. A reset spring 322 is provided between the connecting rods 321 and the bottom surface of the reset grooves 312. The cleaning chamber 33 is disposed on the top of the blocking plate 32. The top and side walls of the cleaning chamber 33 are respectively provided with an inlet 331 and an outlet 332. The outer wall of the top of the cleaning chamber 33 has a deformation groove 333. An elastic buckle 334 is hinged in the deformation groove 333. The sealing cover 34 is embedded in the inlet 331.

[0034] Please see Figure 3 In this embodiment, in order to smoothly pump the liquid out of the storage tank, the opening of the pump head main column 13 is adapted to the shape of the first liquid outlet 311. Furthermore, the top surface of the pump head main column 13 is connected to the bottom surface of the fixing plate 31, so that the top surface of the pump head main column 13 and the bottom surface of the fixing plate 31 are tightly fitted to form a zero-gap sealing interface, which effectively prevents the liquid from leaking back from the joint surface.

[0035] Please see Figure 3 In this embodiment, in order to restrict the vertical movement of the blocking plate 32, the inner wall of the pressing head 2 is provided with an annular limiting plate 24 and is located above the blocking plate 32. When the blocking plate 32 moves vertically along the inner wall of the pressing head 2 and the blocking plate 32 moves upward to a preset height, the bottom surface of the annular limiting plate 24 abuts against the top surface of the blocking plate 32.

[0036] Please see Figure 3In this embodiment, in order to ensure the precise alignment and stable connection between the faucet outlet and the press head 2, the sliding through hole 21 and the alignment groove 22 are coaxially arranged. Furthermore, the bottom of the alignment groove 22 has a closed end face and the radial dimension is larger than the diameter of the sliding through hole 21. The structure formed by the sliding through hole 21 and the alignment groove 22 can be adapted to the faucet outlets of different diameters. The coaxial structure of the two ensures that the water flow scours along the axial direction of the outlet pipe, effectively removing residual emulsion from the pipe wall.

[0037] Please see Figure 5 In this embodiment, in order to prevent the connecting rod 321 from sliding off in the reset groove 312, the inner wall of the reset groove 312 is provided with a first limiting block 3121, and the outer wall of the connecting rod 321 is provided with a second limiting block 3211 that cooperates with the first limiting block 3121. When the connecting rod 321 slides to its maximum stroke, the end faces of the first limiting block 3121 and the second limiting block 3211 come into contact and block each other, so as to prevent the risk of the connecting rod 321 axially coming off in the reset groove 312.

[0038] Please see Figure 6 , Figure 7 In this embodiment, in order to adapt to different usage scenarios and the sealing performance of the connection between the pressing head 2 and the pump head main column 13, the connection method between the pressing head 2 and the pump head main column 13 is one of embedded connection and threaded connection. Multiple connection methods are selected. The embedded connection uses interference fit to achieve quick assembly and axial limit, while the threaded connection can enhance the sealing reliability by tightening the preload.

[0039] Please see Figure 6 In this embodiment, the pressing head 2 and the pump head main column 13 are specifically embedded. The interference fit design of the embedded connection omits the rotation alignment step, and the pressing head 2 can be directly pressed vertically into the pump head main column 13. The interference fit design of the embedded connection omits the rotation alignment step, and the blocking plate 32 can be directly pressed vertically into the fixing plate 31, saving time.

[0040] Example 2

[0041] For the sake of brevity, the parts that are the same as in Embodiment 1 will not be described again. The main focus here is on the structure that is different from Embodiment 1 of this utility model. The only difference between Embodiment 2 and Embodiment 1 is the shape of the cross-section of the inner wall of the scraping tube 24.

[0042] Please see Figure 7 In this embodiment, in order to increase stability and durability, the pressing head 2 and the pump head main column 13 are specifically connected by threads. The bottom inner wall of the pressing head 2 is provided with external threads, and the top outer wall of the pump head main column 13 is provided with internal threads. The two are connected by tightening. A sealing ring or sealant can be added to the threaded connection to further improve the sealing effect.

[0043] In use, press your finger against the sealing cap 34 on the press head 2 and press the cleaning chamber 33 and the blocking plate 32 downwards together. The connecting rod 321 at the bottom of the blocking plate 32 and the return spring 322 cooperate with the return groove 312 on the fixing plate 31, so that the bottom of the blocking plate 33 abuts against the top of the fixing plate 31, blocking the first liquid outlet 311 to prevent liquid leakage. At the same time, the elastic buckle 334 on the top outer wall of the cleaning chamber 33 engages with the bottom of the sliding through hole 21. Then remove the sealing cap 34 and align the faucet outlet with the alignment groove 22 to make it fully engage and align the water inlet 331 with the water inlet 331 at the bottom of the cleaning chamber 33. When cleaning, turn on the faucet to let the water flow through the water inlet 33. 1. The water flows into the cleaning chamber 33, then through the outlet 332 into the inner cavity of the press head 2, and finally out through the inner wall of the outlet pipe 23, thus achieving a rinsing effect. After rinsing, simply pinch the elastic buckle 334 on the top outer wall of the cleaning chamber 33 (the length of the elastic buckle 334 is set so that when it is inserted into the bottom of the sliding hole 21, the top of the elastic buckle 334 has a reserved section for the user to press it back with their finger), so that the elastic buckle 334 retracts into the deformation groove 333, and the cleaning chamber 33 and the blocking plate 32 can be reset and the sealing cover 34 can be embedded into the inlet 331, solving the problem that the pump head cannot be cleaned immediately without disassembly, and that the residue is prone to bacterial growth or oxidation.
