Description

Ultrasonic humidifier and control method thereof

technical field

The invention relates to a humidifier, in particular to an ultrasonic humidifier and a control method thereof.

Background technique

At present, household humidifiers on the market are mainly divided into two categories: ultrasonic humidifiers and cold evaporative humidifiers. The ultrasonic humidifier uses the principle of ultrasonic high-frequency oscillation to atomize water into ultra-fine particles, and through the pneumatic device, the ultra-fine particles (white water mist) are diffused into the air to achieve humidification. The principle of the cold evaporative humidifier is to accelerate the evaporation of water through the fan, and you will not see the white mist sprayed out. Ultrasonic humidifiers have a higher market share due to their high humidification efficiency and low noise, but the disadvantages of ultrasonic humidifiers are that they will generate fog, heavy humidity around the humidifier, and uneven space humidity.

Existing ultrasonic humidifier technologies are mainly divided into two categories according to whether constant humidity control can be achieved. One is a humidifier that manually adjusts the amount of mist emitted by the humidifier. This type of humidifier often comes with a timing function. This type of humidifier does not form a closed loop during control, and it is difficult for users to timely and accurately adjust to the required humidity. , can not achieve constant humidity control. The other type is a humidifier that can realize constant humidity control by installing a humidity sensor in the humidifier body, but the data collected by the humidity sensor of this type of humidifier is actually the humidity around the body, and the so-called constant humidity only represents humidification. The humidity around the humidifier body is constant. Due to the non-uniformity of humidity in the space, constant humidity cannot be achieved at a position far away from the humidifier body. Taking the humidifier in the bedroom as an example, most of the time people stay in the bedroom is for sleeping. The ideal goal of using a humidifier in the bedroom is to keep the bedside position at a comfortable humidity for the human body. Take the conventional humidity sensor installed in the humidifier body as an example. If the humidifier is placed directly at the head of the bed, the user's head can be in a constant humidity close to the humidifier body when sleeping. In the control area, but the white mist generated by the humidifier will be directly inhaled by the user, causing harm to the respiratory tract. At the same time, there will be water accumulation around the head of the bed, so the user cannot place the humidifier directly at the head of the bed, but away from the bed Putting the humidifier on the head will cause the humidifier to fail to achieve constant humidity control at the head of the bed.
