Abstract
Description
Technical Field
[0001] This utility model relates to the field of pumps, and in particular to a push-button pump with anti-accidental touch function. 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 before it pops out to activate. However, existing pumps lack additional measures to prevent accidental opening during transport and sales. Some pumps use plastic sealing to prevent accidental opening, requiring a sharp object like a knife to puncture the seal, adding extra sealing costs and inconvenience. Therefore, there is an urgent need for a pump with anti-accidental activation features to solve these problems. Utility Model Content

[0025] Reference Figures 1 to 4A push-button pump with anti-accidental touch function 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 drive sleeve 30 and a limiting sleeve 40. The pump head 20 is provided with at least one insertion groove 21.
[0026] The limiting sleeve 40 is axially movable on the pump base 10 and has at least one plug-in part 41 thereon;
[0027] The drive sleeve 30 is rotatably mounted on the pump base 10 and connected to the limit sleeve 40, and is used to drive the limit sleeve 40 to move closer to or away from the pump head 20.
[0028] The drive sleeve 30 can drive the limiting sleeve 40 closer to the pump head 20 when the pump head 20 is in a sealed state, so that the insertion part 41 is inserted into the insertion groove 21 to restrict the rotation of the pump head 20 in the second direction; or, the drive sleeve 30 can drive the limiting sleeve 40 away from the pump head 20 when the pump head 20 is in a sealed state, so that the insertion part 41 is separated from the insertion groove 21, 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. Then, the limiting sleeve 40 is fitted onto the upper end of the pump base 10. Next, the drive sleeve 30 is installed on the pump base 10 and connected to the limiting sleeve 40. In some embodiments, the drive sleeve 30 and the limiting sleeve 40 are threadedly connected. By rotating the drive sleeve 30 in the opposite direction, the limiting sleeve 40 is driven away from the pump head 20, thereby connecting the drive sleeve 30 and the limiting sleeve 40 together. Then, the pump head 20 is installed on 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, so that the insertion part 41 on the limiting sleeve 40 is connected to the pump head 20. The insertion slots 21 are arranged opposite each other. The drive sleeve 3 is rotated in the forward direction to drive the limiting sleeve 40 closer to the pump head 20, so that the insertion part 41 on the limiting sleeve 40 is inserted into the insertion slot 21 on the pump head 20. This 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 sealing state of the press pump. When the press pump needs to be used, the limiting sleeve 40 is driven away from the pump head 20 by rotating the drive sleeve 30 in the reverse direction, so that the insertion part 41 on the limiting sleeve 40 is pulled out from the insertion slot 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] Reference Figures 1-3In 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. A third limiting ring 54 is provided on the inner side wall of the drive sleeve 30 and is rotatably located within the annular limiting groove 53. In a further embodiment, the pump base 10 includes a first part 11 and a second part 12. The first limiting ring 51 is provided on the outer side wall of the second part 12, and the second limiting ring 52 is formed by the upper end face of the first part 11. The process of assembling the drive sleeve 30 is as follows: first, the drive sleeve 30 is fitted from bottom to top onto the lower end of the second part 12, so that the third limiting ring 54 abuts against the first limiting ring 51. Then, the second part 12 is installed on the first part 11, preferably by adhesive bonding, so that the drive sleeve 30 is installed between the first part 11 and the second part 12, and the third limiting ring 54 is rotatably located within the annular limiting groove 53.
[0031] Reference Figures 1-3 In some embodiments, the limiting sleeve 40 is connected to the pump seat 10 via a guide structure 60 to allow the limiting sleeve 40 to move axially relative to the pump seat 10. Preferably, the guide structure 60 includes a guide block 61 disposed on the pump seat 10 and a guide groove 62 disposed on the limiting sleeve 40 and arranged along the height direction, with the guide block 61 extending into the guide groove 62. When the drive sleeve 30 and the limiting sleeve 40 are threadedly connected, this arrangement can convert the rotational motion of the drive sleeve 30 into the axial linear motion of the limiting sleeve 40.
[0032] Reference Figures 1-3 In some embodiments, the limiting sleeve 40 is connected to the pump seat 10 through an anti-detachment structure 70 to restrict the separation of the limiting sleeve 40 from the pump seat 10. Preferably, the anti-detachment structure 70 includes a first blocking ring 71 and a second blocking ring 72. The first blocking ring 71 is disposed on the side of the pump seat 10 near the pump head 20, and the second blocking ring 72 is disposed on the inner side wall of the limiting sleeve 40 and located below the first blocking ring 71. During assembly, the limiting sleeve 40 is first arranged opposite to the upper end of the pump seat 10 and fitted in, so that the second blocking ring 72 abuts against the upper end of the first blocking ring 71. Then the limiting sleeve 40 is continued to be fitted in until the second blocking ring 72 passes over the first blocking ring 71 and the lower end of the first blocking ring 71. Furthermore, a movable groove is formed between the first blocking ring 71 and the first limiting ring 51, and the second blocking ring 72 moves axially within the movable groove.
[0033] Reference Figures 1-4 In some embodiments, both the insertion slot 21 and the insertion part 41 are provided in pairs.
[0034] The advantages of this utility model are: by cooperating with the drive sleeve and the limiting sleeve, the press pump is always kept in a sealed state, thereby avoiding accidental entry into the open state, effectively improving the safety during transportation and sales, and meeting the usage requirements.
[0035] 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.
