Abstract
Description
Technical Field
[0001] This utility model relates to the field of pumps, and in particular to a push-button pump that can prevent accidental activation. Background Technology
[0002] Most everyday 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, there is an urgent need for a pump that prevents accidental activation 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 push-button pump that can prevent accidental activation.

[0025] Reference Figures 1 to 4A push-button pump capable of preventing accidental opening 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 sliding sleeve 30 and a reset member 40. The pump head 20 is provided with at least one insertion groove 21.
[0026] The sliding sleeve 30 is axially movable on the pump base 10 and has at least one plug-in portion 31 thereon;
[0027] The reset member 40 is disposed between the sliding sleeve 30 and the pump seat 10, and is used to provide the driving force for the sliding sleeve 30 to move toward the pump seat 10;
[0028] When the pump head 20 is in a sealed state, the plug part 31 can be inserted into the plug groove 21 when the sliding sleeve 30 moves toward the pump head 20, so as to restrict the rotation of the pump head 20 in the second direction; or, when the pump head 20 is in a sealed state, the plug part 31 can be withdrawn from the plug groove 21 when the sliding sleeve 30 moves away from the pump head 20, so that the pump head 20 can rotate in the second direction.
[0029] In this invention, during production, the pump base 10 and pump head 20 are first assembled separately. The reset piece 40 is then installed on the upper end of the pump base 10. Next, the sliding sleeve 30 is fitted onto the upper end of the pump base 10 and abuts against the reset piece 40. Then, the pump head 20 is installed on the pump base 10, and the pump head 20 is rotated 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. The insertion part 41 on the sliding sleeve 30 is moved to approach the insertion groove 21 on the pump head 20. The sliding sleeve 30 is pulled downwards to avoid the pump head 20 until the insertion part 41 aligns with the insertion groove 21. At this point, the sliding sleeve 30 is released. Under the action of the reset member 40, the sliding sleeve 30 approaches the pump head 20, so that the insertion part 41 on the sliding sleeve 30 is inserted into the insertion groove 21 on the pump head 20, which can restrict the relative rotation between the pump head 20 and the pump base 10. That is, the pump head 20 cannot rotate in the first direction or the second direction, thus maintaining the sealed state of the press pump. When the press pump needs to be used, the sliding sleeve 30 is pulled down again to make the sliding sleeve 30 move away from the pump head 20, so that the insertion part 41 on the sliding sleeve 30 is pulled out from the insertion groove 21 on the pump head 20. At this time, the pump head 20 can rotate relative to the pump base 10, that is, the pump head 20 can rotate in the second direction to the open state.
[0030] In some possible embodiments, the upper end of the plug portion 41 has a bevel. During the process of switching the pump head 20 to the sealed state, the pump head 20 will push the plug portion 41 downward through the cooperation of the bevel until the plug portion 41 abuts against the lower end face of the pump head 20 and finally slides into the plug groove 21. This setting eliminates the need to pull down the sliding sleeve 30 during the process of entering the sealed state. The sliding sleeve 30 only needs to be operated once when the press pump is activated, which can improve the convenience of use.
[0031] Reference Figures 1-4 In some embodiments, 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. The inner sidewall of the sliding sleeve 30 is provided with a third limiting ring 54 that is 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. In a further embodiment, the pump base 10 includes a first base body 11 and a second base body 12. The first limiting ring 51 is provided on the outer sidewall 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.
[0032] Specifically, during assembly, the sliding sleeve 30 is first placed on the lower end of the first part 11 from bottom to top, so that the lower end of the third limiting ring 54 abuts against the lower end of the first limiting ring 51. In some possible embodiments, the reset member 40 is set as a helical spring. Then, the helical spring is placed between the first part 11 and the sliding sleeve 30 from bottom to top until the upper end of the helical spring abuts against the lower end of the third limiting ring 54. Finally, the first part 11 is connected to the second part 12. In some possible embodiments, the first seat 11 is glued to the second seat 12.
[0033] Reference Figures 1-4 In some embodiments, the sliding sleeve 30 is connected to the pump seat 10 through a limiting structure 60 to restrict the relative rotation between the sliding sleeve 30 and the pump seat 10; preferably, the limiting structure 60 includes a limiting block 61 disposed on the pump seat 10 and a limiting groove 62 disposed on the sliding sleeve 30 and arranged along the height direction, with the limiting block 61 extending into the limiting groove 62.
[0034] Reference Figures 1-4 In some embodiments, both the insertion slot 21 and the insertion part 31 are provided in pairs.

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.
