Description

Technical Field

[0001] The present invention relates to the technical field of toothpaste pump production, and more particularly to a toothpaste pump that facilitates the extrusion of highly viscous paste. Background Art

[0002] At present, the common toothpaste packages on the market usually include two types: hose packaging and pump packaging bottles. Pump-type toothpaste generally uses a plastic pump container to fill the paste. When in use, pressing the button on the toothpaste head can extrude the toothpaste in the container, simplifying the steps of taking toothpaste, and at the same time, the toothpaste can be taken more thoroughly.

[0003] Most toothpaste pumps on the market usually operate through a spring-loaded piston. When the pump head is pressed, the piston moves downward to push the toothpaste out of the container; when the pump head is released, the spring pulls the piston back to its original position. This action will form a negative pressure area under the piston. If the toothpaste is very viscous, when the piston returns to its original position, it may not be able to quickly suck in enough new toothpaste to fill the chamber, which may cause air to be sucked into the internal space of the pump. When the toothpaste is filled, the air cannot be quickly discharged from the bottle body, thus affecting the stability of the next toothpaste extrusion, and there are many bubbles when extruding next time, and the practicability is poor. Summary of the Invention

[0004] In view of the problems existing in the above-mentioned prior art, the present invention is proposed.

[0005] Therefore, the technical problem to be solved by the present invention is that when the piston returns to its original position, it may not be able to quickly suck in enough new toothpaste to fill the chamber, which may cause air to be sucked into the internal space of the pump. When the toothpaste is filled, the air cannot be quickly discharged from the bottle body, thus affecting the stability of the next toothpaste extrusion, and there are many bubbles when extruding next time, and the practicability is poor.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a toothpaste pump that facilitates the extrusion of highly viscous paste, including an extrusion assembly. The extrusion assembly includes a long tube, a dust cover that cooperates with the long tube, a pressing part that cooperates with the long tube, a first elastic part and a second elastic part located in the long tube. Through the first elastic part and the second elastic part, the highly viscous paste can be stably extruded.

[0007] As a preferred solution of the toothpaste pump that facilitates the extrusion of highly viscous paste according to the present invention, wherein: the long tube includes a floating tube, a chamber and a pressing tube. The pressing tube is fixedly connected to the upper end of the long tube. The chamber is arranged in the long tube. The pressing tube is communicated with the chamber. The floating tube is slidably fitted with the inner cavity of the pressing tube.

[0008] As a preferred embodiment of the toothpaste pump facilitating the extrusion of high-viscosity paste according to the present invention, wherein: the pressing part includes a fitting block, a pressing plate, a clamping groove and a groove. The pressing plate is fixedly connected to one side of the fitting block. The clamping groove is formed on the other side of the fitting block. The clamping groove cooperates with the upper end of the floating tube. The fitting block is assembled in the extrusion tube. The groove is formed at the bottom of the fitting block.

[0009] As a preferred embodiment of the toothpaste pump facilitating the extrusion of high-viscosity paste according to the present invention, wherein: the first elastic part includes an upper piston, a spring and an upper valve plate. The upper piston is slidably fitted with the chamber. The upper piston cooperates with the upper valve plate. One end of the spring contacts a raised plate provided on the circumferential surface of the floating tube, and the other end of the spring contacts the top of the upper piston.

[0010] As a preferred embodiment of the toothpaste pump facilitating the extrusion of high-viscosity paste according to the present invention, wherein: an opening is formed through the top of the upper piston, and the upper valve plate is rotatably connected to the inner wall of the opening.

[0011] As a preferred embodiment of the toothpaste pump facilitating the extrusion of high-viscosity paste according to the present invention, wherein the second elastic part includes a spring piece, a lower piston and a fixing ring. One end of the spring piece is disposed in the chamber. The lower piston is located above the spring piece and contacts the upper end of the spring piece. The fixing ring is disposed at the lower end of the spring piece.

[0012] As a preferred embodiment of the toothpaste pump facilitating the extrusion of high-viscosity paste according to the present invention, wherein: a bottom cover is fixedly connected to the bottom of the long tube, and the fixing ring is disposed on the upper end of the bottom cover.

[0015] As a preferred embodiment of the toothpaste pump facilitating the extrusion of high-viscosity paste according to the present invention, wherein: a convex block is fixedly connected to the outside of the floating tube, and the convex block is engaged with the groove.

[0016] Advantages of the present invention: For the viscous paste toothpaste of the present utility model, during reset, the negative pressure generated by the upward movement of the upper piston in the single-chamber structure directly acts on the paste in the main chamber, with small movement resistance. While in the double-chamber structure, due to an additional small chamber, the negative pressure generated by the upward movement of the upper piston acts on the small chamber, and the paste in the main chamber is sucked in through the opening and closing of the valve, resulting in large pressure loss and small generated acting force.

[0017] 2. The diameter of the single-chamber upper piston is large, generating a large negative pressure and a large acting force on the lower piston, making it more suitable for viscous paste than the double-chamber type.

[0018] 3. Due to the large diameter of the upper piston, the maximum amount of paste discharged per single time also increases, enabling stable control of the amount of paste discharged each time and reducing the usage cost for customers. Brief Description of the Drawings

[0032] Furthermore, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0033] Embodiment 1

[0034] Refer to Figure 1 - Figure 9 , this embodiment provides a toothpaste pump facilitating the extrusion of high-viscosity paste, including an extrusion assembly 100. The extrusion assembly 100 includes a long tube 101, a dust-proof cover 102 cooperating with the long tube 101, a pressing part 103 cooperating with the long tube 101, a first elastic part 104 and a second elastic part 105 located inside the long tube 101. Through the first elastic part 104 and the second elastic part 105, the high-viscosity paste can be stably extruded.

[0035] Furthermore, the long tube 101 includes a floating tube 101b, a chamber 101c, and a pressing tube 101d. The pressing tube 101d is fixedly connected to the upper end of the long tube 101. The chamber 101c is arranged inside the long tube 101. The pressing tube 101d communicates with the chamber 101c. The floating tube 101b is slidably fitted with the inner cavity of the pressing tube 101d.

[0036] Further, the pressing part 103 includes a fitting block 103a, a pressing plate 103b, a clamping groove 103c and a groove 103d. The pressing plate 103b is fixedly connected to one side of the fitting block 103a. The clamping groove 103c is formed on the other side of the fitting block 103a. The clamping groove 103c cooperates with the upper end of the floating tube 101b. The fitting block 103a is assembled in the extrusion tube 101d. The groove 103d is formed at the bottom of the fitting block 103a. [[ID=!]]

[0037] It should be noted that the groove 103d of the fitting block 103a is adapted to the outer side of the floating tube 101b, and one end of the fitting block 103a abuts against the inner wall of the extrusion tube 101d. The upper end opening of the extrusion tube 101d is adapted to the fitting block 103a, so that the fitting block 103a is always in the extrusion tube 101d during the pressing or resetting process of the pressing plate 103b.

[0038] Further, the first elastic part 104 includes an upper piston 104a, a spring 104b and an upper valve plate 104c. The upper piston 104a is slidably fitted with the chamber 101c. The upper piston 104a cooperates with the upper valve plate 104c. One end of the spring 104b contacts the raised plate provided on the circumferential surface of the floating tube 101b, and the other end of the spring 104b contacts the top of the upper piston 104a.

[0039] Further, an opening 104a-1 is formed through the top of the upper piston 104a, and the upper valve plate 104c is rotatably connected to the inner wall of the opening 104a-1.

[0040] It should be noted that the lower end of the floating tube 101b is always in a clamped state with the opening 104a-1, and it does not affect the normal flipping of the upper valve plate 104c.

[0041] In addition, the upper piston 104a directly acts on the paste, and the lifting of the piston is beneficial to sliding sealing and accurately controlling the paste output.

[0042] Further, the second elastic part 105 includes a spring piece 105a, a lower piston 105b and a fixing ring 105c. One end of the spring piece 105a is arranged in the chamber 101c. The lower piston 105b is located above the spring piece 105a. The lower piston 105b contacts the upper end of the spring piece 105a. The fixing ring 105c is arranged at the lower end of the spring piece 105a.

[0043] It should be noted that the outer side of the spring piece 105a is provided with a plurality of curved supporting claw shapes. The resistance between the lower piston 105b and the chamber 101c becomes smaller. With the support of the supporting claws, the lower piston 105b is not easily detached. The spring piece 105a is made of metal or resin material and has good elasticity.

[0044] Further, a bottom cover 101a is fixedly connected to the bottom of the long tube 101, and the fixing ring 105c is arranged on the upper end of the bottom cover 101a.

[0045] It should be noted that multiple claw grooves are provided on the side of the top of the fixed ring 105c that contacts the elastic piece 105a. The support claws of the elastic piece 105a can contact the claw grooves, which can provide a good stable support effect for the elastic piece 105a and ensure the stability of the elastic piece 105a to a certain extent.

[0046] Furthermore, a convex block 101b-2 is fixedly connected to the outside of the floating tube 101b. The convex block 101b-2 is engaged with the groove 103d, which can enable the floating tube 101b to descend as the pressing plate 103b is pressed.

[0047] When in use, when it is necessary to extrude the paste, first press the pressing plate 103b. The pressing plate 103b can drive the floating tube 101b to move downward through the cooperation of the groove 103d and the convex block 101b-2. Since the floating tube 101b is integrally connected to the upper piston 104a, the upper piston 104a also moves downward with the floating tube 101b. The spring 104b is pressed and compressed by the floating tube 101b. Since the upper piston 104a moves downward, the paste is extruded at this time. The upper valve piece 104 is pushed open by the paste, so the toothpaste is extruded through the floating tube 101b. When the pressing plate 103b is released, the spring 104b resets. At this time, the spring 104b pushes the floating tube 101b to move upward. A negative pressure is generated in the chamber 101c, causing the upper valve piece 104c to close. Under the action of the atmospheric pressure, the lower piston 105b moves upward in the chamber 101c. The elastic force of the elastic piece 105a acts on the inner wall of the chamber 101c to generate an irreversible movement, making it difficult for the lower piston 105b to tilt and enabling it to move upward more smoothly. This effectively prevents air from entering during movement and makes the extrusion of the viscous paste more stable.

[0048] Embodiment 2

[0049] Referring to Figure 1 - Figure 9 , this embodiment provides a toothpaste pump that facilitates the extrusion of high-viscosity paste. A plug 101b-1 is inserted at the paste outlet of the floating tube 101b.

[0050] It should be noted that the plug 101b-1 can seal the floating tube 101b when the toothpaste pump is not in use, ensuring the cleanliness of the paste extrusion of the toothpaste pump.

[0051] Furthermore, a plurality of anti-slip protrusions are provided on the upper end of the pressing plate 103b.

[0052] It should be noted that the anti-slip protrusions can prevent slipping when pressing the pressing plate 103b.
