In view of the above-mentioned technical problems, the present invention discloses an atomization device with liquid level detection, which includes a base for storing liquid for atomization, and an integrated module, wherein the integrated module is provided with a main A control circuit and a microporous atomizing sheet, the microporous atomizing sheet is used for atomizing liquid under the control of the main control circuit; it also includes a liquid guiding mandrel, the top of the liquid guiding mandrel is connected to the microporous The bottom of the hole atomizing sheet is in contact, the liquid guiding mandrel extends from the integrated module and enters the base, and the liquid guiding mandrel is used to allow the liquid in the base to crawl to the microporous mist and a mandrel tube, the mandrel tube includes an upper mandrel tube arranged in the integrated module and a lower mandrel tube arranged outside the integrated module, and the liquid guiding mandrel penetrates into the In the mandrel tube, at least part of the lower mandrel tube extends into the base, and the lower end of the lower mandrel tube is provided with a rod liquid inlet, and the rod liquid inlet is used to let the base The liquid inside enters into the mandrel tube to allow the liquid guiding mandrel to be adsorbed; it also includes a metal sleeve for liquid level sensing, the metal sleeve is sleeved on the outside of the lower mandrel tube and generates electrical signals The main control circuit in the integrated module is connected, and there is an interval between the rod liquid inlet and the metal sleeve.

Wherein, the integrated module is provided with a main control circuit and a microporous atomizing sheet, and it is defined that the main control circuit and the microporous atomizing sheet are arranged in the inner cavity of the integrated module. The inner cavity refers to the space enclosed by the components forming the outermost periphery of the integrated module, for example, the space enclosed by the module housing and the lower end cover described below. Wherein, the main control circuit and the microporous atomizing sheet are both integrated components of the integrated module.

Wherein, the microporous atomizing sheet has an atomizing hole, the microporous atomizing sheet is connected with a driving circuit, and the driving circuit can be arranged on the main control circuit and controlled by the main control circuit, so The main control circuit controls the drive circuit to drive the microporous atomizing sheet to vibrate at a high frequency, so that the liquid inside the microporous atomizing sheet is driven by the high-frequency vibrating microporous atomizing sheet to pass through the After the atomization hole is sprayed to the outside, the liquid will be forced to pass through the atomization hole and form droplets with smaller particle size, thereby forming an atomization effect on the outside of the microporous atomizing sheet, thereby Humidifies the nearby air.

Wherein, the liquid-conducting mandrel is made of a material that has capillary action with the liquid in the base so that the liquid can be conducted along the liquid-guiding mandrel. When the amount of liquid in the base is sufficient, the liquid in the base crawls along the liquid-conducting mandrel to the microporous atomizing sheet under the capillary action of the liquid-conducting mandrel, thereby realizing the The purpose of supplying the liquid for atomization to the microporous atomizing sheet is the liquid guiding mandrel. The liquid guiding mandrel can be a liquid guiding cotton sliver.

Wherein, the mandrel tube includes an upper mandrel tube arranged in the integrated module and a lower mandrel tube arranged outside the integrated module, and it is defined that the mandrel tube includes at least the upper mandrel tube and The lower mandrel tube and the upper mandrel tube are located in the inner cavity of the integrated module, and the lower mandrel tube is located outside the inner cavity of the integrated module. The mandrel tube can be an integral structure or a split structure, and is not limited to an integral structure with other components such as the lower end cap described below.

Wherein, the lower end of the lower mandrel tube is provided with a rod liquid inlet, which defines that the lower end of the lower mandrel tube will not prevent the liquid in the base from contacting the lower section of the liquid guiding mandrel, so that all The liquid guiding mandrel can smoothly absorb the liquid in the base.

Wherein, the metal sleeve is sleeved on the outer side of the lower mandrel tube and is electrically connected to the main control circuit in the integrated module, which defines when the liquid level in the base can allow liquid to enter the When the lower mandrel tube is adsorbed to the liquid guide mandrel, and at the same time, the liquid can be brought into contact with the metal sleeve, the metal sleeve, the liquid in the base, and the liquid on the liquid guide mandrel will interact with each other. The microporous atomizing sheet forms a signal communication path to achieve electrical signal conduction with the main control circuit.

Wherein, there is an interval between the rod liquid inlet and the metal sleeve, which defines that when the liquid level in the base does not reach the bottommost end of the metal sleeve, the metal sleeve and the metal sleeve are separated from each other. Due to the interval between the liquids in the base, the resistance increases sharply, and the loop current signal becomes very weak. At this time, an open circuit is almost formed between the metal sleeve and the microporous atomizing sheet.

According to the above technical scheme, compared with the prior art, the beneficial effects of the present invention are:

1. In the present invention, the metal sleeve is sleeved on the outer side of the lower mandrel tube, which is not only compact in structure, but also stable and reliable, and is easy to install and manufacture;

4. The atomizing device of the present invention cleverly uses the metal sleeve, the liquid in the base and the liquid on the liquid guiding mandrel as an electrical signal to connect the intermediate conductor of the microporous atomizing sheet, and then The detection of whether the liquid level in the base reaches the set height can prevent the microporous atomizing sheet from continuing to work when there is not enough liquid, thus protecting the atomizing equipment. Because when the liquid level of the base reaches the set height, the metal sleeve, the liquid in the base, the liquid on the liquid guiding mandrel and the microporous atomizing sheet form a signal communication path to realize It is connected to the electrical signal of the main control circuit. At this time, the microporous atomizing sheet works normally; on the contrary, if the liquid level in the base does not reach the set height, the metal sleeve and the The space between the liquids in the base will cause the resistance to increase sharply and the loop current signal to become very weak. At this time, an open circuit is almost formed between the metal sleeve and the microporous atomizing sheet. The main control circuit controls the microporous atomizing sheet to stop working;

5. The use of the atomizing device of the present invention can also prevent the problem of dry burning of the atomizing device when the liquid guiding mandrel cannot conduct liquid normally, because the liquid guiding mandrel cannot conduct the liquid to all parts. On the microporous atomizing sheet, an open circuit is almost formed between the metal sleeve and the microporous atomizing sheet at this time, and the microporous atomizing sheet will also stop working;

6.
