按压泵及具有该按压泵的液体容器

Abstract

本实用新型公开了一种按压泵及具有该按压泵的液体容器，其中，该按压泵包括泵座、泵体、按压帽及锁套，泵体设在泵座上；按压帽连接在泵体上，用以供使用者按压泵体；锁套设在泵座上且能够绕自身轴线在锁止位置和解锁位置之间转动，锁套的轴线沿上下方向延伸；当锁套位于锁止位置时，锁套与按压帽形成锁止状态，以限制按压帽向下按压，当锁套位于解锁位置时，锁套与按压帽切换至解锁状态，以允许按压帽向下按压。本实用新型的按压泵及液体容器，利用锁套实现了对按压帽的有效锁止与解锁，替代了传统的分离式泵头盖，用户仅需简单旋转锁套即可完成锁止与解锁操作，无需担心泵头盖的取放不便和意外遗失，显著提升了使用的便捷性和操作的简易性。

Claims

1. A squeeze pump characterized by, include: Pump base; Pump body, which is mounted on the pump base; A press cap is attached to the pump body for the user to press the pump body; A locking sleeve, which is disposed on the pump base and is rotatable about its own axis between a locked position and an unlocked position, the axis of which extends in the vertical direction; When the lock sleeve is in the locked position, the lock sleeve and the pressing cap form a locked state to restrict the pressing cap from pressing down. When the lock sleeve is in the unlocked position, the lock sleeve and the pressing cap switch to the unlocked state to allow the pressing cap to press down.

2. The squeeze pump of claim 1, wherein The pressing cap and the locking sleeve are arranged coaxially, and a locking structure is provided between the pressing cap and the locking sleeve; The locking structure includes a protrusion and a groove, one of which is provided on the lock sleeve, and the other of which is provided on the pressing cap, the groove extending along the axial direction of the lock sleeve; When the lock sleeve is in the locked position, the protrusion is misaligned with the groove and prevents the pressing cap from moving downward. When the lock sleeve is in the unlocked position, the protrusion is aligned with the groove to allow the pressing cap to move downward, and the protrusion slides in the groove when the pressing cap moves downward.

3. The squeeze pump of claim 2, wherein The locking sleeve is fitted over the outside of the pressing cap, the protrusion is provided on the inner wall of the locking sleeve, and the groove is provided on the outer wall of the pressing cap.

4. The squeeze pump of claim 1, wherein The outer wall of the pressing cap is provided with a spray nozzle, and the peripheral wall of the locking sleeve is provided with an opening. When the locking sleeve is in the locked position, the spray nozzle is misaligned with the opening and hidden in the locking sleeve. When the locking sleeve is in the unlocked position, the spray nozzle is opposite to the opening so that the spray nozzle can spray liquid outward.

5. The squeeze pump of claim 1 wherein, The upper end of the lock sleeve is an open end, and the pressing cap is located inside the open end. The peripheral wall of the lock sleeve is provided with a finger position opening, which communicates with the open end, so that the user's fingers can be placed and pressed on the pressing cap.

6. The push pump according to claim 4, characterized in that, The pressing cap includes a first peripheral wall portion and a central column, the central column being located within the first peripheral wall portion and having a liquid channel; The pump body has a liquid outlet pipe, the upper end of which is connected to the central column, and the liquid channel connects the liquid outlet pipe to the spray nozzle.

7. The squeeze pump of claim 6, wherein The pressing cap further includes a second peripheral wall portion, which is coaxially disposed on the inner side of the first peripheral wall portion; the pump seat has an upwardly protruding annular platform, which slides in conjunction with the second peripheral wall portion.

8. The squeeze pump of claim 7, wherein One of the annular platform and the second peripheral wall is provided with a guide bar, which extends in the vertical direction. The other of the annular platform and the second peripheral wall is provided with a guide groove, which slides in conjunction with the guide bar in the vertical direction.

9. The squeeze pump of claim 1 wherein, The lower end of the locking sleeve is provided with an annular groove, and the upper end of the pump base is provided with an insertion groove for the lower end of the locking sleeve to be inserted into, and the inner wall of the insertion groove is provided with a buckle. When the lower end of the locking sleeve is inserted into the insertion slot, the buckle engages with the annular slot and allows the locking sleeve to rotate relative to the pump base.

10. A liquid container characterized by comprising: include: solution bottle; The press pump as claimed in any one of claims 1 to 9, wherein the pump base is provided at a mouth of the solution bottle.
