Description

Technical Field

[0001] This utility model relates to the field of press pump technology, and in particular to a press pump-type toothpaste pump that is easy to vent air. Background Technology

[0002] Press pumps are widely used for dispensing paste and liquid products. They are convenient dispensing devices widely used in daily chemicals (such as facial cleansers and hand creams), pharmaceuticals (such as ointments and gels), and food (such as sauces and creams). Their core function is to achieve quantitative and clean output of products through mechanical pressing, avoiding contamination and waste caused by open containers. Toothpaste pumps often use a press pump structure.

[0003] Existing toothpaste pumps typically use a piston driven by pressing to create negative pressure for dispensing. The piston and tube are in a fixed relative position. As the toothpaste is consumed, a cavity easily forms at the bottom of the tube, making it impossible for the pump chamber to maintain an effective negative pressure. This results in slower, more laborious, or even no toothpaste dispensed, especially when the amount of toothpaste remaining is small. Furthermore, many components are connected by threads or adhesives, making disassembly cumbersome during cleaning and maintenance, easily damaging components, and making them difficult to reuse.

[0005] In view of the problems existing in the above and / or existing easy-to-vent press-type toothpaste pumps, this utility model is proposed.

[0006] Therefore, the problem that this utility model aims to solve is that the piston and the tube body are in a fixed relative position. As the paste is consumed, a cavity is easily formed at the bottom of the tube body. The pump chamber cannot maintain an effective negative pressure, resulting in slower paste output, more effort, or even no output. Secondly, most of the components are connected by threads or adhesives, making disassembly cumbersome during cleaning and maintenance, easily damaging the components, and not easy to reuse.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an easy-to-vent press-type toothpaste pump, comprising: a press-pump assembly including a tube body, a button provided at the top of the tube body, a lower piston movably connected to the bottom of the inner cavity of the tube body, a bottom cover fixed at the bottom of the tube body, an air valve fixed in the inner cavity of the lower piston; and a toothpaste dispensing assembly, fixed at the top of the inner cavity of the tube body, including a pump plug movably connected to the inner wall of the tube body, a spring valve fixed in the inner cavity of the pump plug, a floating tube fixed at the top of the spring valve, a spring sleeved on the outer ring of the floating tube, and a plug fixed at the top of the toothpaste dispensing assembly.

[0008] As a preferred embodiment of the easy-to-vent press-type toothpaste pump of this utility model, the bottom cover has vent holes on both sides of the top, the vent holes are connected to the atmosphere, and the outer ring of the bottom cover is engaged with the bottom of the inner cavity of the tube.

[0009] As a preferred embodiment of the easy-to-vent press-type toothpaste pump of this utility model, wherein: an outer retaining ring is fixed to the top of the outer ring of the tube body, a dust cover is fixed to the top of the outer ring of the tube body, an inner retaining ring is fixed to the inner ring of the dust cover, and the inner retaining ring and the outer retaining ring are engaged in a snap-fit ​​manner.

[0010] As a preferred embodiment of the easy-to-vent press-type toothpaste pump of this utility model, one end of the spring is fixed to the surface of the floating tube, and the other end of the spring is fixed to the inside of the tube body.

[0011] As a preferred embodiment of the easy-to-vent press-type toothpaste pump of this utility model, wherein: a valve plate is fixed in the inner cavity of the elastic valve, and an elastic rib is fixed between the outer ring of the valve plate and the inner ring of the elastic valve.

[0012] As a preferred embodiment of the easy-to-vent press-type toothpaste pump of this utility model, one end of the plug is fixed to the opening of the floating tube, and the sealing surface of the plug is in mate with the inner cavity of the floating tube.

[0013] As a preferred embodiment of the easy-to-vent press-type toothpaste pump of this utility model, the surface of the floating tube is fixed with a rotating shaft, the button is rotatably connected to the outer ring of the rotating shaft, and one end of the button extends to the top of the inner cavity of the tube.

[0014] As a preferred embodiment of the easy-to-vent press-type toothpaste pump of this utility model, wherein: a sealing surface one is provided at the center of the pump plug, and a sealing surface two is provided at the center of the spring valve, and the sealing surface one and the sealing surface two are in a sealing fit.

[0015] As a preferred embodiment of the easy-to-vent press-type toothpaste pump of this utility model, the inner ring of the pump plug is fixed with a retaining ring, and the bottom of the outer ring of the floating tube is provided with a retaining groove, wherein the retaining ring is sealed to the inner wall of the retaining groove.

[0016] As a preferred embodiment of the easy-to-vent press-type toothpaste pump of this utility model, wherein: the outer ring of the pump plug is sealed to the inner wall of the tube body, and the outer ring of the lower piston is sealed to the inner wall of the tube body.

[0017] The beneficial effects of this utility model are as follows: By using the paste dispensing component, the piston remains stationary under atmospheric pressure when the paste is squeezed out from the floating tube, creating a negative pressure inside the tube. This causes the lower piston to move upward under atmospheric pressure, thus achieving a self-adjusting effect. This ensures that the space between the lower piston and the tube is always filled with paste, resulting in a rapid paste dispensing effect. This avoids the situation where conventional press pumps cannot dispense paste quickly due to a reduction in the amount of paste inside. Furthermore, the multi-structure snap-fit ​​design allows for quick disassembly. Attached Figure Description

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0033] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides an easy-to-vent press-type toothpaste pump. The easy-to-vent press-type toothpaste pump includes a press pump assembly 1 and a toothpaste dispensing assembly 2. Through the press pump assembly 1 and the toothpaste dispensing assembly 2, a self-adjusting effect can be achieved, so that the space between the lower piston and the tube body is always filled with toothpaste, thereby achieving a rapid toothpaste dispensing effect. Moreover, by using a multi-structure snap-fit ​​method, the disassembly process is greatly simplified and the maintenance efficiency of the device is improved.

[0034] Specifically, the press pump assembly 1 includes a tube body 11, a button 14 is provided on the top of the tube body 11, a lower piston 17 is movably connected to the bottom of the inner cavity of the tube body 11, a bottom cover 13 is fixed to the bottom of the tube body 11, and an air valve 16 is fixed to the inner cavity of the lower piston 17.

[0035] The bottom cover 13 forms a sealed protection for the bottom of the tube body 11, preventing external impurities from entering the tube body 11 and contaminating the ointment. At the same time, the vent 131 on the top allows the tube body 11 to communicate with the atmosphere, providing air pressure for the upward movement of the lower piston 17, ensuring the stable operation of the self-adjusting function. Furthermore, the snap-fit ​​between the bottom cover 13 and the tube body 11 allows for quick disassembly, facilitating subsequent cleaning or component replacement.

[0036] The air valve 16 balances the air pressure on both sides of the lower piston 17 during its movement, preventing the lower piston 17 from getting stuck due to excessive pressure difference. It also prevents the ointment from seeping back into the inner cavity of the lower piston 17, further ensuring the sealing and safety of the ointment. The air valve 16 and the lower piston 17 are connected by a snap-fit ​​to form an air passage for venting, which is convenient for installation. Before installing the lower piston 17 and the tube body 11, the lower piston 17 is separated from the air valve 16. When the lower piston 17 is installed, the air in the tube body 11 is discharged from the air passage. After the air in the tube body 11 is completely discharged, the snap-fit ​​locks in place to seal again.

[0037] Specifically, the ointment dispensing component 2 is fixed at the top of the inner cavity of the tube body 11, including a pump plug 24 movably connected to the inner wall of the tube body 11, a spring valve 23 fixed in the inner cavity of the pump plug 24, a floating tube 21 fixed at the top of the spring valve 23, a spring 22 sleeved on the outer ring of the floating tube 21, and a plug 15 fixed at the top of the ointment dispensing component 2.

[0038] Example 2, refer to Figures 2-10 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, it also includes that both sides of the top of the bottom cover 13 are provided with vent holes 131, which are connected to the atmosphere, and the outer ring of the bottom cover 13 is engaged with the bottom of the inner cavity of the tube body 11.

[0040] Specifically, an outer retaining ring 111 is fixed to the top of the outer ring of the tube body 11, a dust cover 12 is fixed to the top of the outer ring of the tube body 11, and an inner retaining ring 121 is fixed to the inner ring of the dust cover 12. The inner retaining ring 121 and the outer retaining ring 111 are engaged in a snap-fit ​​manner.

[0041] By engaging the outer retaining ring 111 with the inner retaining ring 121, the dust cover 12 and the tube body 11 can be quickly and securely fastened. The dust cover 12 can effectively prevent the button 14 from being accidentally pressed when not in use, and at the same time prevent external dust from adhering to the button 14 or the opening of the floating tube 21, reducing the risk of external dust contaminating the paste. In addition, the fastening structure facilitates the quick disassembly and installation of the dust cover 12, making it flexible and convenient to use.

[0042] Specifically, one end of the spring 22 is fixed to the surface of the floating tube 21, and the other end of the spring 22 is fixed to the inside of the tube body 11.

[0043] Specifically, a valve plate 231 is fixed in the inner cavity of the elastic valve 23, and an elastic rib 232 is fixed between the outer ring of the valve plate 231 and the inner ring of the elastic valve 23.

[0044] The elastic valve 23 can achieve automatic reset and sealing by its own elasticity. The valve plate 231 in its inner cavity cooperates with the elastic rib 232. When pressed, the valve plate 231 can be rotated to open, ensuring that the paste is squeezed out smoothly. When the button 14 is released, the elastic rib 232 resets and the valve plate 231 closes quickly, preventing air from entering the pump cavity and disrupting the negative pressure environment. At the same time, the elastic valve 23 cooperates with the sealing surface of the pump plug 24, which can further enhance the sealing of the pump cavity and reduce the risk of paste leakage.

[0045] Specifically, one end of the plug 15 is fixed to the opening of the floating tube 21, and the sealing surface of the plug 15 is fitted with the inner cavity of the floating tube 21.

[0046] Specifically, a rotating shaft 25 is fixed to the surface of the floating tube 21, and the button 14 is rotatably connected to the outer ring of the rotating shaft 25. One end of the button 14 extends to the top of the inner cavity of the tube body 11.

[0047] Specifically, a sealing surface one is provided at the center of the pump plug 24, and a sealing surface two is provided at the center of the spring valve 23. The sealing surface one and the sealing surface two are in a sealing fit to prevent the paste in the floating tube 21 from flowing back to the outside air after the button 14 is released.

[0048] Specifically, the inner ring of the pump plug 24 is fixed with a retaining ring 241, and the bottom of the outer ring of the floating tube 21 is provided with a retaining groove 26, and the retaining ring 241 is sealed to the inner wall of the retaining groove 26.

[0049] By engaging the retaining ring 241 with the retaining groove 26, a sealed connection can be achieved between the pump plug 24 and the floating tube 21, preventing the ointment from leaking from the connection point. At the same time, the retaining structure does not require thread or adhesive fixation and can be directly disassembled by force, which greatly simplifies the disassembly process, improves the maintenance efficiency of the device, and achieves a quick disassembly effect.

[0050] Specifically, the outer ring of the pump plug 24 is sealed to the inner wall of the tube body 11, and the outer ring of the lower piston 17 is sealed to the inner wall of the tube body 11.

[0051] When in use, press the pressing end of button 14. Button 14 rotates around the rotating shaft 25 on the floating tube 21. At the same time, the rotating shaft 25 is pressed down by the contact fulcrum between button 14 and tube body 11. As a result, the overall compression spring 22 composed of floating tube 21, pump plug 24, spring valve 23 and button 14 moves downward. Due to atmospheric pressure, the lower piston 17 does not move. The paste is forced through the valve plate 231 of spring valve 23 and squeezed out of the pump body through the outlet of floating tube 21.

[0052] When button 14 is released, under the action of spring 22, button 14, floating tube 21, pump plug 24 and spring valve 23 are reset. At the same time, since the bottom cover 13 has a vent hole 131 that is connected to the atmosphere, under the action of atmospheric pressure, the lower piston 17 moves upward, thereby rising with the paste to achieve a self-adjusting effect.

[0053] During disassembly, the bottom cover 13 and the bottom of the inner cavity of the tube body 11 can be directly disassembled by force. The button 14 can be disassembled from the top of the tube body 11. Then, the internal components of the ointment dispensing assembly 2 can be disassembled one by one. The sealing structure between the pump plug 24 and the floating tube 21 can be directly disassembled. The sealing structure between the pump plug 24 and the tube body 11 can also be directly disassembled by force. No threaded disassembly or removal of adhesive is required, which greatly improves the disassembly efficiency.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
