WATER TANK WITH A LIMITING ASSEMBLY

摘要

A water tank has a container, a micro switch, a limiting assembly and a float. The float is mounted slidably in the container. The limiting assembly has an actuating rod that slides in a direction perpendicular to the sliding path of the float. An inclined guiding track is mounted between the float and the actuating rod to convert the moving direction. Since the actuating rod utilizes the movement to switch the micro switch on and off, the actuating rod and the micro switch need no abutting structures. Therefore, when the actuating rod is moved by an accidental force, the actuating rod self-moves back to its original position once the accidental force is removed. Then the micro switch is switched on again so that the household appliance is restarted without any extra acts by a user.

主权项

1. A water tank comprising:
a hollow shell; a hollow container mounted slidably in the shell; a micro switch mounted on an outside wall of the shell and having a lever mounted pivotally on the outside wall of the shell; a limiting assembly mounted in the container and having
an actuating rod mounted slidably in the container, selectively sliding along a first axis and having
an outer end selectively abutting a side of the lever of the micro switch; andan inner end; anda guiding track attached securely to the actuating rod and aligning with a second axis; and a float mounted slidably in the container, limited to selectively slide along a third axis and having a protrusion formed on a top end of the float and mounted slidably in the guiding track of the limiting assembly, wherein the second axis and the first axis intersect to form an angle less than 180 degrees, and the third axis is perpendicular to the first axis.
