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 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 and 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 before it pops out to activate. However, current pumps lack additional measures to prevent accidental opening during transport and sales. Some pumps rely on 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 address these issues. Utility Model Content

[0020] Reference Figures 1 to 4 A push-button pump designed to prevent accidental activation includes a pump base 10 and a pump head 20 threadedly connected to the pump base 10. The pump head 20 has a sealed state and an open state. The pump head 20 can enter the sealed state when rotated in a first direction to approach the pump base 10, or enter the open state when rotated in a second direction to move away from the pump base 10. The pump head 20 also includes a stop sleeve 30. A first threaded groove 21 is provided on the inner side wall of the lower end of the pump head 20, and a first threaded section 31 is provided on the outer side wall of the upper end of the stop sleeve 30. The lower end of the stop sleeve 30 is movably connected to the pump base 10. When the pump head 20 is in the sealed state, the first threaded section 31 can be threadedly connected to the first threaded groove 21 to prevent the pump head 20 from rotating in the second direction.

[0021] In this invention, during production, the pump base 10 and pump head 20 are first assembled separately. The stop sleeve 30 is then fitted onto the upper end of the pump base 10. The pump head 20 is then mounted on the pump base 10 via a threaded connection structure. The pump head 20 is then rotated in the first direction until it enters a sealed state. In this sealed state, the pump head 20 is positioned close to the pump base 10. At this time, the first threaded section 31 on the stop sleeve 30 is aligned with the first threaded groove 21 on the pump head 20. The stop sleeve 30 is then rotated so that the first threaded section 31 is threaded into the first threaded groove 21. In some embodiments, the helical direction of the first threaded section 31 and the first threaded groove 21 is aligned with that of the pump base 10 and the pump head 20. The spiral directions of 0 are opposite. For example, the pump base 10 and the pump head 20 rotate in the first direction to enter the sealed state and rotate in the second direction to enter the open state. By setting the spiral directions to be opposite, the stop sleeve 30 is threadedly connected to the first threaded groove 21 when rotating in the first direction. If the user wants to rotate the pump head 20 to the open state in the second direction, it will drive the stop sleeve 30 to rotate in the second direction as well. When the stop sleeve 30 rotates in the second direction, it is away from the pump head 20. The pump head 20 also rotates in the second direction and is away from the stop sleeve 30. Therefore, the pump head 20 cannot rotate in the second direction at this time, and thus cannot enter the open state, resulting in accidental opening.

[0022] Reference Figures 1-4 In some embodiments, the outer side wall of the pump base 10 is provided with a first blocking ring 41 and a second blocking ring 42 arranged opposite each other in the axial direction to form an annular blocking groove 43. The inner side wall of the blocking sleeve 30 is provided with a third blocking ring 44 located in the annular blocking groove 43. The third blocking ring 44 can rotate and move axially within the annular blocking groove 43. Specifically, the first blocking ring 41 is close to the pump head 20, and the second blocking ring 42 is formed by one end face of the pump base 10. When installing the blocking sleeve 30, the blocking sleeve 30 is sleeved on the upper end of the pump base 10, so that the third blocking ring 44 on the blocking sleeve 30 abuts against the first blocking ring 41. Then the blocking sleeve 30 is pressed towards the pump base 10 until the third blocking ring 44 passes over the first blocking ring 41 and enters the annular blocking groove 43. This allows the blocking sleeve 30 to be movably connected to the pump base 10 without affecting the axial and rotational movement of the blocking sleeve 30 relative to the pump base 10.

[0023] Reference Figures 1-4 In some embodiments, a second threaded groove 51 is provided on the inner sidewall of the lower end of the blocking sleeve 30, and a second threaded section 52 is provided on the side of the annular blocking groove 43 away from the pump head 20. The second threaded section 52 is threaded into the second threaded groove 51. When the pump is in the open state, the blocking sleeve 30 and the pump seat 10 can be fixed together by making the second threaded section 52 threaded into the second threaded groove 51, so as to prevent the blocking sleeve 30 from shaking on the pump seat 10 and improve the user experience.

[0024] Reference Figures 1-4 In some embodiments, the pump base 10, the first stop ring 41 and the second stop ring 42 are integrally injection molded, and the stop sleeve 30 and the third stop ring 44 are integrally injection molded.

[0025] The advantages of this invention are: by setting a stop sleeve to prevent the pump head in the sealed state from rotating in the second direction, it avoids accidental entry into the open state, effectively improving the safety during transportation and sales, and meeting the usage requirements.

[0026] 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.
