Water level control device of humidifier and humidifier applying same

Abstract

The invention discloses a water level control device of a humidifier and the humidifier applying the same. The water level control device comprises a water tank and a base of the humidifier, wherein a steam generating chamber is arranged in the base; a drain hole is formed in the water tank, and a drain valve is arranged in the drain hole; the water level control device in sleeved connection with the drain valve is arranged in the steam generating chamber, the water level control device comprises a limiting hood opened in the peripheral wall, a water outlet is formed in the top of the limiting hood, and a floating block is arranged in the limiting hood; a leak hole plug is arranged at the water outlet, and the bottom of the leak hole plug is a part in contact with the floating block; the floating block shifts up and down in the limiting hood along with change of the water level; when the floating block is in contact with the drain hole plug, the water outlet is plugged to stop draining; otherwise, the floating block is separated from the leak hole plug, and the water outlet is opened to supplement water. The water control device disclosed by the invention is simple in structure and small in occupied space, is immediately triggered to control water supplementation for the steam generating chamber, and is electric energy-saving, and the condition that the humidifier is likely to overflow or dry out is effectively avoided, so that a user can use the humidifier safely.

Description

technical field [0001] The invention relates to the field of steam home appliances, in particular to a water level control device for a humidifier and a humidifier using the device. Background technique [0002] With the development of science and technology, people's living standards are improving day by day, and people's requirements for living environment are gradually increasing. Among them, air humidity is one of the important factors affecting comfort, especially in northern China and places where air conditioners are used for a long time, the environment is very dry, and corresponding equipment should be used to increase the humidity of the air to adjust a comfortable living environment. Therefore, household humidifiers are becoming more and more popular with families and become one of the necessary household appliances. [0003] Humidifiers currently on the market are generally composed of a water tank and a base. The base is provided with a steam generating chamber...

AI Technical Summary

Problems solved by technology

The water level control device in the prior art is generally a lever type or a solenoid valve type. The lever type water level control device needs to be equipped with a floating block connected to one end of the lever, and the horizontal setting of the lever occupies a large internal space, and the trigger speed is slow, so it cannot control water replenishment in time. , the water level control effect is poor; and the solenoid valve type water level control device, although the response speed is fast, but because the trigger is too sensitive, the switch is frequently activated, resulting in easy damage, and the structure is complex and consumes a lot of power.

Therefore, for the water level control device of the current upward water type humidifier, it is still a research problem for major manufacturers.
