WATER TANK WITH A MAGNETIC REED SWITCH

摘要

A water tank is mounted in a household appliance and has a shell, a container, a float and a magnetic reed switch. The container is mounted slidably in the shell. The float is mounted pivotally in the container and has an actuating rod. The magnetic reed switch is mounted securely on the outside wall of the shell and corresponds to and separates from the actuating rod. Since the actuating rod utilizes magnetic force to switch the magnetic reed switch on and off, the actuating rod and the magnetic reed switch need no abutting structures. Therefore, when the actuating rod is pivoted by an accidental force, the actuating rod self-pivots back to the original position once the accidental force is removed. Then the magnetic reed switch is switched on again so that the household appliance is restarted without extra acts by a user.
