Description

Technical Field

[0001] The utility model relates to the technical field of humidifiers, in particular to a humidifier with an automatic shutdown function for a water tank. Background Art

[0002] Traditional humidifiers usually require manual operation to start and stop, or set a timer to run until it shuts down, or work until it shuts down due to lack of water. However, when users add water to the humidifier or need to clean the humidifier, they often forget to turn off the machine before operating it. Then, directly extracting the water tank during operation will have certain hidden dangers and reduce the user experience.

[0003] When a traditional humidifier is operating normally, when its water tank is lifted, the machine will continue to work. At this time, without the protection of the water tank, the water droplets in the atomized oscillating part of the water tank will splash everywhere, and the body may directly contact the sprayed water mist. If the waterproof performance of the whole machine is high, it is also necessary to strengthen the prevention of accidents caused by direct water droplets leaking into the machine. In addition, the principle of the ultrasonic atomizer is to use the high-frequency vibration of the atomizer to break up the water into tiny droplets. The water droplets sprayed by the ultrasonic humidifier when it is working are where the ultrasonic energy is more concentrated. When the user touches it directly with his hand, there will be an obvious tingling sensation, because the energy of the ultrasonic wave will directly penetrate the skin, so there will be a tingling sensation similar to electric shock, which has great hidden dangers.

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] See also Figures 1 to 4A humidifier with a water tank automatic shutdown function comprises a water tank assembly 1 and a water tank 2, the water tank assembly 1 is covered and connected to the water tank 2, the water tank 2 is provided with an atomizing sheet 5 (not shown), the water tank 2 is provided with a guide column 21, a sensor 22 is installed in the guide column 21, a sensing float 23 which can rise and fall with the water level in the water tank 2 is installed on the guide column 21, the sensing float 23 is inductively matched with the sensor 22, the sensor 22 is communicatively connected with the atomizing sheet 5, the water tank assembly 1 is provided with a top abutting portion 11 opposite to the sensing float 23, and the top abutting portion 11 can abut against the sensing float 23. A guide column 21 is provided in the water tank 2, a sensor 22 is installed in the guide column 21, and a sensing float 23 that floats with the water level is installed on the guide column 21, and a top abutting portion 11 that abuts the sensing float 23 is provided in the water tank assembly 1. When the water tank assembly 1 covers the water tank 2, the top abutting portion 11 presses down the sensing float 23 so that the sensor 22 can detect the sensing float 23, indicating that the water tank assembly 1 covers the water tank 2; when the water tank assembly 1 is lifted, the sensing float 23 loses the effect of the top abutting portion 11 and floats up, and the sensor 22 cannot detect the sensing float 23, indicating that the water tank is lifted and the atomizing sheet 5 stops working, thereby avoiding the problem of water droplets splashing everywhere without the water tank blocking, and effectively avoiding the problem of tingling sensation after the user touches it.

[0023] See also Figures 1 to 3 Preferably, a limit pressure cover 24 is fixedly installed on the top of the guide column 21, and the maximum sensing height of the sensor 22 is lower than the limit pressure cover 24.

There is a certain height difference between the maximum sensing height of the sensor 22 and the limit pressure cover 24, so when the water tank assembly 1 is lifted, the sensor 22 cannot detect the sensing float 23 after the float floats a certain distance; the sensing area of ​​the sensor 22 in the vertical direction is lower than the installation height of the atomizer sheet 5 in the water tank 2. The detection mechanism of the sensor 22 is divided into two situations: a. When the induction float 23 floats above the detection area of ​​the sensor 22, that is, the water level is relatively high, if there is no top support part 11 to press the float and sink to the sensing area, the machine cannot work. The water tank assembly 1 must be installed to press the float and sink to the sensing area through the top support part 11 so that the machine can operate normally; b.

[0026] See also Figures 1 to 3 Preferably, the top of the guide column 21 is provided with an external thread, the limit pressure cover 24 is provided with an internal thread, and the limit pressure cover 24 is rotatably fixed on the guide column 21.

[0027] See also Figures 1 to 3 Preferably, the outer diameter of the limiting gland 24 is larger than the inner diameter of the sensing float 23 , so as to limit the sensing float 23 on the guide column 21 .

It is sufficient to be able to abut against the induction float 23.

[0030] See also Figures 1 to 3 Preferably, the guide column 21 is fixed on the bottom surface of the water tank 2, a cavity is provided in the guide column 21, and the sensor 22 is installed in the cavity to prevent the sensor 22 from wading.

[0034] The utility model has the following working principle:

[0035] Step S101: When the humidifier is powered on and the water level in the water tank 2 is sufficient for operation, the control module 3 starts to monitor the Hall sensor signal in real time; if the water tank is gradually lifted and the magnetic float floats up and leaves the sensing area of ​​the Hall sensor, the Hall sensor disconnection signal is a stable low-level signal; when the water tank assembly 1 is assembled in place, the magnetic float is affected by the top support 11 and its floating stroke is reduced to the sensing area of ​​the Hall sensor, then the Hall sensor conduction signal is a stable high-level signal.

[0036] Step S102: When the control module 3 monitors the change of the Hall sensor signal, it determines whether to control the humidifier to automatically shut down (that is, whether the atomizer 5 is working) based on the change of the Hall sensor signal; when it is monitored that the Hall sensor is currently in a low-level state with the water tank lifted: 1. If the humidifier is in the on-state, the machine will automatically shut down directly; 2. If the humidifier is in the standby state, the machine cannot be turned on and run; when the Hall sensor detects that the magnetic floating signal is at a high level, the surface water tank assembly 1 is assembled in place, and the humidifier can be in normal on-state operation.
