Detailed Description
In order to better understand the purpose, structure and function of the present invention, a humidifier and a water shortage control method thereof according to the present invention will be described in further detail with reference to the accompanying drawings.
The invention provides a control method of a humidifier, which comprises the following steps:
s1: continuously detecting a water shortage signal within a set time after starting up, and recording the triggering times of the water shortage signal after the time is over;
specifically, when the humidifier is in a starting state, after water is added into the water tank, the water needs to flow onto the atomizer through the water discharging channel for a certain time, the preferable set time range is 5s to 10s, the existing water tank can be subjected to false alarm protection within the set time range, and the water tank is considered to be in a water shortage state.
The water shortage signal of the water tank is obtained, and whether the water shortage exists is judged by comparing the oscillation voltage and the voltage threshold value when the atomizer works.
S2: and if the triggering times are greater than a set threshold value, determining that the water is in a water shortage state.
The controller records the times of the water shortage signals, sets the threshold value to be 3 times to 5 times, confirms that the water tank is in shortage when the continuous water shortage signals are recorded to be 3 times to 5 times, and reports the water shortage protection to remind a user.
Specifically, the humidifying gears of the humidifier are divided into a low gear and a high gear, the humidifier stops running in the low gear for a period of time after acquiring a water shortage signal every time, water shortage protection is reported after detection until the number of times of acquiring the water shortage signal is greater than a set threshold, and the humidifier runs in the normal middle or high gear if the number of times of recording the water shortage signal is less than the set threshold.
The reason that the humidifier detects the lack of water signal and can arouse the wrong report lies in can vibrate the atomizing piece with water when the atomizer vibrates around, the center of atomizing piece is concave, vibrate the condition that can appear the wrong report when all around when water, water all around can flow back to atomizing piece center department after a period of time, for not lack of water state this moment, so set for the number of times of acquireing the lack of water signal and be greater than and set for the threshold value, more accurate for the detection, improve user experience.
The invention also provides a humidifier, which comprises a water tank for storing water and an atomizer, wherein the atomizer is provided with an atomizing sheet, the atomizing sheet is arranged in the water tank to atomize the water in the water tank, and the humidifier also comprises:
