Water outlet valve assembly, water tank using water outlet valve assembly and humidifier

Abstract

The invention discloses a water outlet valve assembly, a water tank using the water outlet valve assembly and a humidifier. The water outlet valve assembly comprises a water draining portion, a valvebody, an ejection rod, a first elastic portion and an isolator; the water draining portion is provided with a first water outlet flow channel; the valve body is arranged at a water outlet of the firstwater outlet flow channel; the ejection rod and the first elastic portion are fixedly connected with the valve body; and the isolator is arranged in the first water outlet flow channel and provided with a second water outlet flow channel, when the isolator is not subjected to the action of the ejection rod, the isolator is located at the first position, the second water outlet flow channel does not communicate with the first water outlet flow channel, and when the isolator is subjected to the action of the ejection rod after moving on the ejection rod for a preset distance, the isolator is located at the second position, and the second water outlet flow channel communicates with the first water outlet flow channel. According to the water outlet valve assembly, the water tank using the water outlet valve assembly and the humidifier, the water outlet valve assembly provides multiple water outlet protection, is simple in structure and can be disassembled to be cleaned, the water leakageprobability is extremely low, and then the reliability is improved.

Description

technical field [0001] The invention relates to household appliances, in particular to a water outlet valve assembly, a water tank and a humidifier using the water outlet valve assembly. Background technique [0002] The top-filling humidifier can directly add water from the water-filling cover set on the upper part of the water tank. It is easy to operate and easy to use, so it is liked by the majority of users. However, the pressure in the water tank of the humidifier is affected by the atmospheric pressure, and water is easy to overflow between the water tank and the base of the humidifier. It is necessary to set up a water valve structure that can effectively control the water supply to control the water outlet. The water outlet valve structure of the water tank of the common humidifier on the market is mostly single. Sealing structure, and the commonly used water tank outlet valve structure is mostly a sealing structure at the water inlet of the valve. This kind of wate...

Problems solved by technology

However, the pressure in the water tank of the humidifier is affected by the atmospheric pressure, and water is easy to overflow between the water tank and the base of the humidifier. It is necessary to set up a water valve structure that can effectively control the water supply to control the water outlet. The water outlet valve structure of the water tank of the common humidifier on the market is mostly single. Sealing structure, and the commonly used water tank outlet valve structure is mostly a sealing structure at the water inlet of the valve. This kind of water outlet valve has a simple structure and relatively low manufacturing and assembly costs. Therefore, most manufacturers will choose this water outlet valve structure.

However, the reliability of the single-seal structure is not high. Once the seal fails, it is easy to cause water leakage, and after water leakage occurs on electrical equipment, it may cause accidents such as electric leakage, which threatens the safety of users, so the reliability is poor.
