Water dispenser liquid gravity energization control device

Abstract

Provided is a water dispenser liquid gravity energization control device. The water dispenser liquid gravity energization control device comprises a microswitch, a warp board, an external magnetic block, an internal magnetic block, an elastic component and a cylinder; one end of the warp board is movably installed on a microswitch body, the other end of the warp board is the free end, a touch point of the microswitch is located at the lower end of the warp board, and the warp board enables the touch point to switch between disconnection and connection through lifting or pressing; the external magnetic block is fixedly connected to the free end of the warp board; the internal magnetic block divides the inner cavity of the cylinder into a cavity A and a cavity B which are not communicated; a liquid inlet which is communicated with the cavity A is formed outside the cylinder; when the internal magnetic block moves along the inner wall of the cylinder in a one-way mode, magnetic force between the internal magnetic block and the external magnetic block is gradually increased; the elastic component is installed in the cavity B, and the elastic component is compressed or loosened along with movement of the internal magnetic block; the microswitch is located outside the cylinder and fixed relative to the cylinder. The water dispenser liquid gravity energization control device is used for controlling the energization state of an electric heater in a water dispenser, and the effects that when no water exists in a heating bin or the liquid level in the heating bin is lower than a certain height, the electric heater is deenergized, and when the liquid level in the heating bin reaches a certain height, the electric heater is energized are achieved.

Description

technical field [0001] The invention relates to a protection device for preventing circuit overload, in particular to a water dispenser liquid gravity energization control device. Background technique [0002] Most of the water dispensers are equipped with a water shortage protection device to prevent the electric heater from burning dry. Most of the existing water shortage protection devices use a temperature control switch or a liquid level float switch or a water level sensor associated with the control circuit to control the electric heater. The electronic components of this type of water shortage protection device are easy to age when used at high temperature for a long time, or the sensitivity is reduced due to fouling. Moreover, this type of solution involves electronic components and control circuits, and the application cost is relatively high. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art...
