Abstract
Description
Technical Field
[0001] This utility model relates to the field of emulsion pump technology, specifically a novel composite resin emulsion pump. Background Technology
[0002] An emulsion pump is a device specifically designed for pumping solids, liquids, or gases, especially in cosmetic packaging. It is a specialized tool for extracting the contents. Based on the principle of atmospheric balance, emulsion pumps apply pressure to draw liquid out of the bottle while allowing outside air to enter, thus achieving the function of liquid distribution.
[0003] A typical emulsion pump consists of components such as a pump head, upper pump column, locking cap, gasket, bottle cap, pump core, lower pump column, spring, pump body, glass bulb, and straw.
[0004] However, current emulsion pumps have the following shortcomings in daily use: 1. During repeated up and down pressing, the pressing head on the top of the emulsion pump is easy to fall off, thus affecting subsequent pressing; 2. The main materials of emulsion pumps include plastic materials such as PE, PP, and LDPE, resulting in poor overall rigidity and poor aging resistance.
[0005] Therefore, a novel composite resin emulsion pump needs to be designed to solve the problems mentioned above. Utility Model Content
[0006] The purpose of this invention is to provide a novel composite resin emulsion pump to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A novel composite resin emulsion pump includes a pump body, a connecting cover on the top of the pump body, an abutment tube extending through the upper part of the connecting cover, a pressing head connected above the abutment tube, a transmission block fixedly connected to the bottom of the abutment tube, a spring connected to the bottom of the transmission block, a conduit fixedly connected to the bottom of the pump body, and a limit structure provided between the lower part of the pressing head and the upper part of the connecting cover.
[0009] As a preferred embodiment of this utility model, the limiting structure includes limiting slide rods fixedly installed on the bottom of the left and right sides of the pressing head, a limiting block is fixedly connected to the bottom of the limiting slide rod, and a fixed bottom rod is connected to the lower outer side of the limiting slide rod.
[0010] As a preferred embodiment of this utility model, the limiting slide rod slides up and down inside the fixed base rod, and the diameter of the limiting block is larger than the inner diameter of the fixed base rod.
[0011] As a preferred embodiment of this utility model, mounting seats are also fixedly connected to the top left and right sides of the limiting slide rod, and the limiting slide rod is adhered and fixed by epoxy resin glue through the mounting seats.
[0012] As a preferred embodiment of this utility model, a rotating slider is provided on the lower outer side of the fixed base rod.
[0013] As a preferred embodiment of this utility model, a rotating slide rail is also arranged around the upper interior of the connecting cover, and the rotating slide rail and the rotating slider are matched and slidably connected.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. In this utility model, a novel composite resin emulsion pump is provided, in which a limiting structure is provided between the bottom of the emulsion pump and the connecting cover. During the up-and-down pressing of the press head, the limiting slide rod is simultaneously driven to slide inside the fixed base rod. Since the limiting block slides up and down inside the fixed base rod and the diameter of the limiting block is larger than the inner diameter of the fixed base rod, the internal separation of the limiting slide rod and the fixed base rod can be prevented, thereby preventing the risk of the press head falling off.
[0016] 2. In this utility model, a novel composite resin emulsion pump is provided. Since the emulsion pump is made entirely of a novel composite resin material, compared with existing plastic materials, the emulsion pump using the novel composite resin material can improve the overall rigidity and aging resistance of the pump body, and can maintain the appearance and performance of the emulsion pump for a long time.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0026] For examples, please refer to Figure 1-4 This utility model provides a technical solution:
[0027] A novel composite resin emulsion pump includes a pump body 1, a connecting cover 2 on the top of the pump body 1, an abutment tube 3 extending through the upper part of the connecting cover 2, a pressing head 4 connected above the abutment tube 3, a transmission block 5 fixedly connected to the bottom of the abutment tube 3, a spring 6 connected to the bottom of the transmission block 5, a conduit 7 fixedly connected to the bottom of the pump body 1, and a limit structure 8 provided between the lower part of the pressing head 4 and the upper part of the connecting cover 2.
[0028] Specifically, the limiting structure 8 includes limiting slide rods 81 fixedly installed on the bottom of the left and right sides of the pressing head 4. The bottom of the limiting slide rod 81 is fixedly connected to a limiting block 82, and a fixed base rod 83 is connected to the lower outer side of the limiting slide rod 81. The limiting slide rod 81 slides up and down inside the fixed base rod 83, and the diameter of the limiting block 82 is larger than the inner diameter of the fixed base rod 83. Mounting seats 9 are also fixedly connected to the top left and right sides of the limiting slide rod 81. The limiting slide rod 81 is adhered and fixed by epoxy resin glue through the mounting seats 9. During the pressing process of the pressing head 4, the limiting slide rod 81 is simultaneously driven to slide inside the fixed base rod 83. Since the limiting block 82 slides up and down inside the fixed base rod 83 and the diameter of the limiting block 82 is larger than the inner diameter of the fixed base rod 83, the internal separation of the limiting slide rod 81 and the fixed base rod 83 can be prevented, thereby preventing the risk of the pressing head 4 falling off.
[0029] Among them, a rotating slider 10 is provided on the lower outer side of the fixed base rod 83; a rotating slide rail 11 is also provided around the upper inner side of the connecting cover 2, and the rotating slide rail 11 and the rotating slider 10 are matched and slidably connected, so as not to affect the rotation of the pressing head 4.
[0030] Specifically, all components of the emulsion pump are made of composite resin material. Because the emulsion pump is made of a new type of composite resin material, compared with existing plastic materials, the emulsion pump using the new composite resin material can improve the overall rigidity and aging resistance of the pump body, and can maintain the appearance and performance of the emulsion pump for a long time.
[0031] The working process of this utility model is as follows: When using this novel composite resin emulsion pump, by pressing down on the pressing head 4, the pump cavity inside the pump body 1 expands, generating negative pressure to draw in the material. When the hand is released, the pump cavity inside the pump body 1 shrinks, generating negative pressure to discharge the material. Thus, the liquid can be pumped by manually pressing down on the pump head. During the up-and-down pressing of the pressing head 4, the limiting slide rod 81 is simultaneously driven to slide inside the fixed base rod 83. Since the limiting block 82 slides up and down inside the fixed base rod 83 and the diameter of the limiting block 82 is larger than the internal diameter of the fixed base rod 83, the internal separation of the limiting slide rod 81 and the fixed base rod 83 can be prevented, thereby preventing the risk of the pressing head 4 falling off.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
