Referring to fig. 1-3, fig. 1 is a perspective view of a humidifying device 1 according to an embodiment of the present invention, fig. 2 is an exploded perspective view of the humidifying device 1 shown in fig. 1, and fig. 3 is an exploded perspective view of the humidifying device 1 shown in fig. 1 from another angle. The embodiment of the utility model provides a humidification device 1, it includes atomizer 10, first casing 20, ultrasonic wave formula level sensor 90 and automatically controlled subassembly 60.
The atomizer 10 is used for atomizing a liquid to be atomized to generate a liquid mist; the first shell 20 is provided with a liquid storage cavity 21 for containing the liquid to be atomized; the ultrasonic liquid level sensor 90 is configured to send an ultrasonic signal to the liquid to be atomized in the liquid storage cavity 21 and receive a reflected signal of the ultrasonic signal; the electronic control assembly 60 is electrically connected with the ultrasonic liquid level sensor 90, and is used for judging the liquid level of the liquid to be atomized in the liquid storage cavity 21 according to the reflection signal and controlling the liquid level of the liquid to be atomized to work on the humidifying device 1.
It will be appreciated that the ultrasonic level sensor 90 is a sensor that converts an ultrasonic signal into another energy signal, typically an electrical signal. Ultrasonic waves are mechanical waves with a vibration frequency higher than 20 kHz. It has the features of high frequency, short wavelength, less diffraction, high directivity, directional propagation, etc. The penetration of ultrasound waves into liquids is great, especially in sunlight-opaque solids, so that the monitoring of the level of the liquid to be atomized in the humidifying device 1 using the ultrasonic level sensor 90 is very accurate.
Compared with the prior art, the utility model discloses in humidification device 1, through setting up ultrasonic wave formula level sensor 90 is right stock solution chamber 21 treat that atomized liquid sends ultrasonic signal, and through to automatically controlled subassembly 60 sends reflection signal, makes automatically controlled subassembly 60 basis reflection signal judges in the stock solution chamber 21 treat the liquid level of atomized liquid, and the foundation treat the liquid level control of atomized liquid humidification device 1's work can treat when atomized liquid is not enough or lacks the liquid, timely control humidification device 1's operating condition avoids humidification device 1 burns futilely and causes the component damage, prolongs humidification device 1's life.
Specifically, the number of the ultrasonic liquid level sensors 90 is at least two, and the electronic control assembly 60 is electrically connected to the two ultrasonic liquid level sensors 90 respectively, wherein the electronic control assembly 60 is configured to control the operation of the humidifying device 1 according to one of the two reflection signals received by the two ultrasonic liquid level sensors 90, which has a smaller corresponding liquid level, or the electronic control assembly 60 is configured to control the operation of the humidifying device 1 according to an average value of the two reflection signals received by the two ultrasonic liquid level sensors 90. It can be understood that, when the two reflected signals received by the two ultrasonic liquid level sensors 90 are different in liquid level, in order to ensure the safety of the operation of the humidifying device 1, one of the two reflected signals corresponding to a smaller liquid level may be selected to control the operation of the humidifying device 1, or the average value of the two reflected signals received by the two ultrasonic liquid level sensors 90 may be calculated to control the operation of the humidifying device 1, so as to sequentially improve the monitoring accuracy of the ultrasonic liquid level sensors 90. The electric control assembly 60 is through according to two ultrasonic wave formula level sensor 90 is received two correspond the less control of liquid level in the reflected signal humidification device 1's work, perhaps electric control assembly 60 is according to two ultrasonic wave formula level sensor 90 is received two reflected signal's average value controls humidification device 1's work can make electric control assembly 60 is right the calculation of liquid level is more accurate in humidification device 1, discovery that can be more accurate treat that atomized liquid is not enough or the scarce liquid to more accurate control humidification device 1's operating condition.
Further, the electronic control assembly 60 is used for controlling the humidifying device 1 to perform humidifying operation, stop humidifying operation or perform liquid adding reminding according to the liquid level of the liquid to be atomized. Through the basis treat the liquid level control of atomized liquid humidification device 1 carries out humidification work, stops humidification work, or carries out the liquid feeding and reminds, can make humidification device 1 is more intelligent, is protecting humidification device 1 in, provides multiple use for the user and selects, makes user experience better.
Further, the first housing 20 further includes a liquid mist chamber 22 for the liquid mist to flow through, the humidifying device 1 further includes a second housing 30, the second housing 30 is covered on one side of the first housing 20 and has a mist outlet 321, the mist outlet 321 corresponds to the liquid mist chamber 22 so that the liquid mist is discharged through the mist outlet 321, and the ultrasonic liquid level sensor 90 is disposed on one side of the second housing 30 adjacent to the first housing 20. Through with ultrasonic wave formula level sensor 90 set up in second casing 30 is close to one side of first casing 20, can prevent ultrasonic wave formula level sensor 90 is wetted by liquid fog, can be in again simultaneously treat that the atomizing liquid top is right treat the liquid of atomizing liquid monitors, has ensured ultrasonic wave formula level sensor 90's safety in utilization and the accuracy of control.
