Description

Technical Field

[0001] This utility model relates to the field of push pumps, and in particular to an improved push pump. Background Technology

[0002] Existing push pumps have a locking structure that locks and unlocks by rotating the push head, and during the locking or unlocking process, a raised part is used to generate a tactile feel when locking and unlocking.

[0003] For example, patent document CN213832812U discloses an all-plastic pump with an external elastomer, including a pusher, threads, a plastic pressure spring, a locking cover, a main column, a secondary column, a piston, a body, and a plastic ball on a one-way valve seat at the lower end of the body. The locking cover has an axial guide groove and a circumferential arc-shaped guide locking groove on its annular spring seat. The main column has an axial guide rail and a locking block at the lower end of the axial guide rail. The main column slides with the center hole of the annular spring seat, and the axial guide rail slides with the axial guide groove. In the natural state, the axial guide rail and the axial guide groove are opposite each other, and the locking block is located in the axial guide groove. In the locked state, the locking block is engaged with the locking part.

[0004] However, in the above technology, the convex strip has poor elasticity, resulting in a poor feel when locking and unlocking. Furthermore, with prolonged use, the convex strip wears down and may even lose its feel.

[0005] Therefore, an improved push-pump is proposed to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an improved press pump with the advantages of better locking and unlocking feel.

[0007] The technical solution adopted by this utility model to solve the problem is: an improved push pump, comprising: a body, in which a mounting base is installed, the mounting base is provided with a protrusion, a push member is movably inserted into the mounting base, the push member is provided with a spring sheet, the spring sheet extends vertically, and a deformation space is formed on the inner side of the spring sheet, so that when the push member rotates at a certain angle, the spring sheet can pass over the protrusion.

[0008] As a further improvement to the above technical solution, one side of the protrusion is a locking area, and the other side of the protrusion is a pressing area. Multiple limiting blocks are provided on the inner wall of the mounting base. The limiting blocks are located in the locking area. A limiting strip is also provided between the locking area and the pressing area. The limiting strip is spaced apart from the protrusion. When the spring is located in the locking area, the limiting block abuts against the lower end of the spring.

[0009] As a further improvement to the above technical solution, the bottom of the mounting base is provided with a limiting ring, the inner edge of the limiting ring is provided with a guide groove, and the pressing member is provided with a guide block; when the spring is located in the locking area, the guide block is located on the limiting ring, and when the spring is located in the pressing area, the guide block is located in the guide groove.

[0010] As a further improvement to the above technical solution, it also includes a threaded cap and a spring. A pressing head is fixedly installed on the pressing member. A flange is provided on the outer wall of the mounting base. The flange is pressed between the threaded cap and the body. The spring is sleeved on the pressing member and located inside the spring piece. The bottom of the spring abuts against the limiting ring.

[0011] The beneficial effects of this utility model are: the unlocking and locking feel is obtained by the compression of the spring and the convex strip. Since the spring extends downward and has deformation space on the inner side, it has better elasticity, thus making the feel better. Attached Figure Description

[0024] Reference Figures 1 to 6 An improved push-button pump includes: a body 1, a mounting base 2 installed in the body 1, a protrusion 21 on the mounting base 2, a pressing member 3 movably inserted into the mounting base 2, and a spring piece 31 provided on the pressing member 3. The spring piece 31 extends vertically, and a deformation space is formed on the inner side of the spring piece 31. When the pressing member 3 is rotated at a certain angle, the spring piece 31 can pass over the protrusion 21. When the pressing member 3 is rotated, the spring piece 31 can produce an unlocking or locking feel when it contacts the protrusion 21 and moves away from the protrusion 21. Furthermore, because the spring piece 31 extends downward and has a deformation space on its inner side, it has better elasticity, thus providing a better feel and preventing loss of feel due to wear.

[0025] In a preferred embodiment, one side of the protrusion 21 is a locking area 23, and the other side is a pressing area 24. Multiple limiting blocks 25 are provided on the inner wall of the mounting base 2. The limiting blocks 25 are located within the locking area 23. A limiting strip 26 is also provided between the locking area 23 and the pressing area 24, with the limiting strip 26 spaced apart from the protrusion 21. When the spring piece 31 is located in the locking area 23, the limiting block 25 abuts against the lower end of the spring piece 31. In the locked state, the spring piece 31 is located within the locking area 23, and the limiting block 25 abuts against the spring piece 31, preventing the pressing member 3 from pressing down. When unlocking, rotating the pressing member 3 causes the spring piece 31 to rotate towards the pressing area 24. One end of the spring piece 31 contacts the protrusion 21 and springs up, generating a tactile sensation. When the spring piece 31 fully enters the pressing area 24, the other end of the spring piece 31 moves away from the protrusion 21 and springs back, generating a tactile sensation again. Conversely, unlocking also generates two tactile sensations.

[0026] In a preferred embodiment, the bottom of the mounting base 2 is provided with a limiting ring 27, and the inner edge of the limiting ring 27 is provided with a guide groove 271. The pressing member 3 is provided with a guide block 32. When the spring piece 31 is located in the locking area 23, the guide block 32 is located on the limiting ring 27; when the spring piece 31 is located in the pressing area 24, the guide block 32 is located in the guide groove 271. The correspondence between the guide block 32 and the guide groove 271 can be used to further lock and press the pressing member 3.

[0027] As a preferred embodiment, it also includes a threaded cap 4 and a spring 6. A pressing head 5 is fixedly installed on the pressing member 3. A flange is provided on the outer wall of the mounting base 2. The flange is pressed between the threaded cap 4 and the body 1. The spring 6 is sleeved on the pressing member 3 and located inside the spring piece 31. The bottom of the spring 6 abuts against the limiting ring 27.

[0028] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
