Water dispenser with automatic power-off function

Abstract

The invention provides a water dispenser with an automatic power-off function. The water dispenser comprises a casing, a heating device, a power module and a power switch mechanism. The power switch mechanism comprises a rotating block, a protrusion block, a guiding shaft, a rotating cylinder, a central shaft, a coil spring, a limiting component and a power switch-on component. The surface of thecasing is recessed to form a mounting cavity, and the guiding shaft is mounted in the mounting cavity. The rotating cylinder sleeves the guiding shaft, passes through the rotating block, and is fixedto the rotating block. The central shaft is connected to the guiding shaft. The central lines of the central shaft and the guiding shaft are on the same line. A gap is formed between the central shaftand the inner wall of the rotating cylinder. The inner end of the coil spring is fixed to the central shaft. The outer end of the coil spring is fixed to the inner wall of the rotating cylinder. Theprotrusion block is protruded from one side face of the rotating block. The limiting component is mounted on the inner wall of the mounting cavity. By the water dispenser with the automatic power-offfunction, the problem that the protrusion block is liable to wear because the protrusion block needs to be in clamping fit with a groove and needs to slide relative to the inner wall of the mounting cavity in the prior art is solved.

Description

technical field [0001] The invention relates to a water dispenser, in particular to a water dispenser with the function of automatically turning off the power supply. Background technique [0002] In the prior art, the power switch mechanism is used to control the opening and closing of the closed circuit formed by the power supply and the heating device in the water dispenser. The power switch mechanism includes: a rotating block, a bump and a power connection component. The installation chamber, the rotating block can be rotatably installed in the installation chamber, the inner wall of the installation chamber is recessed to form a groove, and the protrusion that matches the groove protrudes from the rotating block, and the inner wall of the groove is snap-fitted with the protrusion. The power connection component is installed below, and the power connection component is provided with an elastic member, which can keep the power connection component disconnected under the ...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a water dispenser with the function of automatically turning off the power supply, which solves the problem in the prior art that the bumps are easily worn because the bumps need to snap fit with the grooves and the bumps need to slide relative to the inner wall of the installation cavity.
