Abstract
Description
Technical Field
[0001] This utility model relates to the field of pumps, and in particular to a self-locking, accident-proof push-button pump. Background Technology
[0002] Most everyday household products like shower gel, shampoo, and hand cream are packaged in bottles, and a pump draws and dispenses the liquid. These pumps can be categorized as lotion pumps or foam pumps. Existing pumps typically have a sealing mechanism to prevent accidental activation during transport or sales; the pump needs to be rotated a certain angle to pop out before it can be activated. However, existing pumps lack additional measures to prevent accidental opening during transport and sales. Some pumps use plastic sealing to prevent accidental opening, but this requires puncturing the seal with a sharp object like a knife, adding extra sealing costs and inconvenience. Therefore, a self-locking, accident-proof pump is urgently needed to solve these problems. Utility Model Content
[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a self-locking, accident-proof push-button pump.

[0028] Reference Figures 1 to 5 A self-locking anti-accidental touch push pump includes a pump base 10 and a pump head 20. The pump head 20 is rotatably mounted on the pump base 10 and has a sealed state and an open state. The pump head 20 can enter the sealed state when rotated in a first direction to be close to the pump base 10, or enter the open state when rotated in a second direction to be away from the pump base 10. It also includes a backstop sleeve 30 and a reset member 40. The pump head 20 is provided with at least one ratchet 21.
[0029] The anti-reverse sleeve 30 is axially movable on the pump base 10 and has at least one ratchet groove thereon;
[0030] The reset member 40 is disposed between the anti-reverse sleeve 30 and the pump seat 10, and is used to provide the driving force for the anti-reverse sleeve 30 to move toward the pump seat 10;
[0031] The ratchet 21 can extend into the ratchet groove when the pump head 20 is in a sealed state to restrict the rotation of the pump head 20 in the second direction; or, the ratchet 21 can be withdrawn from the ratchet groove when the anti-reverse sleeve 30 moves away from the pump head 20, so that the pump head 20 can rotate in the second direction.
[0032] In this utility model, preferably, the pump base 10 is provided with a first limiting ring 51 and a second limiting ring 52 arranged axially at intervals to form an annular limiting groove 53. A third limiting ring 54 is provided on the inner wall of the anti-reverse sleeve 30, axially movable within the annular limiting groove 53. The two ends of the reset member 40 abut against the second limiting ring 52 and the third limiting ring 54, respectively. Further, the pump base 10 includes a first base body 11 and a second base body 12. The first limiting ring 51 is disposed on the outer wall of the first base body 11, and the second limiting ring 52 is formed by the upper end face of the second base body 12. The first base body 11 is mounted on the second base body 12. The assembly process is as follows:
[0033] First, assemble the first base 11, the second base 12, and the pump head 20 respectively. Then, install the anti-reverse sleeve 30 from top to bottom on the upper end of the first base 11. Specifically, first, align the lower end of the anti-reverse sleeve 30 with the upper end of the first base 11 and insert it, so that the third limiting ring 54 abuts against the upper end of the first limiting ring 51. Then, continue pressing until the third limiting ring 54 passes over the first limiting ring 51 and enters the lower end of the first limiting ring 51. Next, install the reset member 40 from bottom to top on the lower end of the first base 11. The reset member 40 is located between the first base 11 and the anti-reverse sleeve 30, and the upper end of the reset member 40 abuts against the lower end of the third limiting ring 54. Then, connect the first base 11 to the second base 12, so that the lower end of the reset member 40 abuts against the upper end face of the second base 12. Preferably, the first base 11 is glued to the second base 12.
[0034] Furthermore, the pump head 20 is installed on the upper end of the pump base 10, and the pump head 20 is operated to rotate in the first direction until it enters a sealed state. In the sealed state, the pump head 20 is positioned close to the pump base 10. During the operation of rotating the pump head 20 in the first direction, the pump head 20 rotates and moves closer to the pump base 10. The ratchet 21 on the pump head 20 abuts against the anti-reverse sleeve 30, which will push the anti-reverse sleeve 30 downward until the ratchet 21 is aligned with the ratchet groove on the anti-reverse sleeve 30 (not shown in the figure, preferably with the same shape as the ratchet 21). At this time, the anti-reverse sleeve 30 will move towards the pump head 20 under the action of the reset member 40, thereby causing the ratchet 21 to enter the ratchet groove. In a further embodiment, the ratchet 21 The pump head 20 is arc-shaped and its height gradually decreases along the first direction. It has a circumferentially arranged guide surface 22 and a first anti-reverse straight surface 23 located near the second direction. Correspondingly, the ratchet has a second anti-reverse straight surface. When the ratchet 21 enters the ratchet, the second anti-reverse straight surface will abut against the first anti-reverse straight surface 23, thereby restricting the rotation of the pump head 20 in the second direction and realizing the self-locking retention of the press pump's sealed state. When the press pump needs to be used, the anti-reverse sliding sleeve 30 is pulled down to move the anti-reverse sliding sleeve 30 away from the pump head 20, so that the ratchet 21 on the pump head 20 is pulled out from the ratchet on the anti-reverse sliding sleeve 30. At this time, the pump head 20 can rotate relative to the pump base 10, that is, the pump head 20 can rotate to the open state along the second direction.
[0035] Reference Figures 1-4 In some embodiments, a movable groove 60 is formed between the lower end face of the anti-reverse sleeve 30 and the upper end face of the second seat 12, so that the anti-reverse sleeve 30 has a movable space when the third limiting ring abuts against the first limiting ring; this setting enables the anti-reverse sleeve 30 to always have a certain movable space, which meets the requirements of the pump head 20 entering the sealed state and locking, as well as the requirements of releasing the sealed state of the pump head 20 and switching to the open state.
[0036] Reference Figures 1-4In some embodiments, the height of the movable groove 60 is greater than the height of the ratchet 21; this arrangement can ensure that the anti-locking sleeve 30 is movable while allowing the ratchet 21 to fully extend into the ratchet groove, thereby improving the stability of the self-locking mechanism.
[0037] Reference Figures 1-4 In some embodiments, the anti-reverse sleeve 30 is connected to the pump seat 10 through a limiting structure 70 to restrict the relative rotation between the anti-reverse sleeve 30 and the pump seat 10; preferably, the limiting structure 70 includes a limiting block 71 disposed on the pump seat 10 and a limiting groove 72 disposed on the anti-reverse sleeve 30 and arranged along the height direction, with the limiting block 71 extending into the limiting groove 72.
[0038] Reference Figures 1-4 In some embodiments, the reset member 40 is configured as a helical spring.
[0039] Reference Figures 1-4 In some embodiments, the pump base 10, pump head 20, and anti-reverse sleeve 30 are all injection molded from plastic.
[0040] Reference Figures 1-5 In some embodiments, the ratchet teeth 21 are preferably two in number and symmetrically arranged on the lower end face of the pump head 20, and the ratchet grooves are multiple and evenly distributed on the upper end face of the anti-reverse sleeve 30.
[0041] The advantages of this utility model are: the cooperation between the anti-reverse sliding sleeve and the reset component ensures that the press pump is always in a sealed state, thereby preventing accidental entry into the open state, effectively improving safety during transportation and sales, and meeting usage requirements.
[0042] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
