If the oil dripping is insufficient, the atomization core will burn, which is inconvenient for users. In order to solve the inconvenience of oil dripping operation, a manual oil squeezing structure has also appeared on the market. The oil dripping mode is improved by squeezing oil, but automatic oil filling cannot be achieved, and there is a problem of atomization core burning due to insufficient oil squeezing. For the oil storage atomizer, a liquid storage structure is provided inside it, and the liquid storage structure can continuously supply oil to the atomizer, but it is necessary to use an oil guide medium (such as cotton, etc.) to achieve physical oil guide, and there are problems of poor taste restoration and stability.

[0025] Different from the prior art, the dripping type atomizer needs to drip or squeeze the oil manually, which is inconvenient for users to use, and the oil storage type atomizer needs to use an oil guide medium (such as cotton, oil guide cloth, etc.) to achieve physical oil guide, which has the problem of poor taste restoration and stability. The present invention provides an automatic liquid injection device, which aims to achieve automatic liquid injection and ensure the restoration and stability of the liquid after atomization. Please refer to the following embodiments for the specific structure of the automatic liquid injection device.

[0026] Please refer to Figures 1 to 3 , Figure 1 This is a module block diagram of an automatic liquid injection device according to an embodiment of the present invention; Figure 2 A block diagram of a module of an automatic liquid injection device according to another embodiment of the present invention; Figure 3 It is a structural schematic diagram of an automatic liquid filling device according to an embodiment of the present invention. In an embodiment of the present invention, the automatic liquid filling device is applied to an atomizer. The atomizer can automatically fill with liquid. Specifically, the atomizer includes an atomizing core 110, a liquid storage tank 120 for storing atomizable liquid, and a liquid inlet pipe 500, one end of which can be immersed in the atomizable liquid in the liquid storage tank 120 and the other end of which is connected to the atomizing core 110. The automatic liquid filling device includes: a liquid level detection module 200 for collecting liquid level information of the atomizable liquid in the liquid inlet pipe 500, a circuit control module 300 electrically connected to the liquid level detection module 200 and used to process the liquid level information to generate a liquid inlet control signal, and a liquid inlet module 400 electrically connected to the circuit control module 300 and replenishing the atomizable liquid / gas to the liquid storage tank 120 according to the liquid inlet control signal.

[0027] Specifically, the above-mentioned atomizer core 110 can atomize the atomizable liquid to form an aerosol, and the liquid storage tank 120 stores part of the atomizable liquid, which can be atomized by the atomizer core 110 several times. The atomizable liquid in the liquid storage tank 120 is directly transported to the atomizer core 110 through the liquid inlet pipe 500, without passing through the liquid-conducting medium, and is directly drained through the liquid inlet pipe 500, which can improve the restoration and stability of the taste of the atomizable liquid after atomization, and improve the user's taste. With the consumption of the liquid in the liquid storage tank 120 during liquid suction, the atomizable liquid in the liquid storage tank 120 gradually decreases, resulting in less or no liquid in the liquid inlet pipe 500. At this time, the liquid level detection module 200 can detect the liquid level of the liquid in the liquid inlet pipe 500 in real time. When there is no liquid in the liquid inlet pipe 500, the liquid level detection module 200 collects the liquid level information and transmits it to the liquid inlet module 400. The circuit control module 300 processes the liquid level information and generates a liquid inlet control signal for controlling the operation of the liquid inlet module 400. The liquid inlet module 400 can replenish the atomizable liquid / gas to the liquid storage tank 120 according to the liquid inlet control signal, so as to change the gas pressure of the liquid storage tank 120 so that the liquid inlet pipe 500 automatically drains the liquid in the liquid storage tank 120 to realize automatic liquid inlet. Specifically, the automatic liquid injection device also includes a housing 600, and the above-mentioned liquid storage tank 120, liquid inlet pipe 500, liquid level detection module 200, circuit control module 300 and liquid inlet module are all arranged in the housing 600, and the atomizing core 110 is arranged on the housing 600.

[0028] In a specific embodiment, the liquid level detection module 200 includes a light source 210 disposed near the liquid inlet pipe 500 and used to emit light, and a signal collector 220 for collecting light passing through the liquid inlet pipe 500 to generate a light signal, and the signal collector 220 is electrically connected to the circuit control module 300 and is used to transmit the light signal to the circuit control module 300. In this solution, the light source 210 can emit directional light or scattered light. For scattered light, it is necessary to extract the part of the light emitted by the light source 210 that passes through the liquid inlet pipe 500. For directional light, the part of the light that passes through the liquid inlet pipe 500 is directly used. The signal collector 220 can receive the light emitted from the liquid inlet pipe 500 to generate a light signal. There are two types of the above-mentioned light signals, the first light signal and the second light signal. Among them, the first light signal is a signal that the light passes through the liquid, and the second light signal is a signal that the light directly extends out of the liquid inlet pipe 500. By comparing the parameters of the first light signal and the second light signal, such as the refractive index, absorbance and other parameters, it can be determined whether there is atomizable liquid in the liquid inlet light. Specifically, if the parameter corresponds to the first optical signal, it can be determined that there is liquid in the liquid inlet pipe 500 according to the first optical signal. If the parameter corresponds to the second optical signal, it can be determined that there is no liquid in the liquid inlet pipe 500 according to the second optical signal. The specific parameters can be set according to the actual liquid and the material of the liquid inlet pipe 500. The circuit control module 300 can generate a liquid inlet control signal according to the second optical signal and transmit it to the liquid inlet module 400, and the liquid inlet module 400 replenishes the atomizable liquid / gas to the liquid storage tank 120 according to the liquid inlet control signal.

[0029] In a specific embodiment, the light source 210, the liquid inlet pipe 500 and the signal collector 220 are located on the same straight line, and the liquid inlet pipe 500 is located between the light source 210 and the signal collector 220. The light emitted by the light source 210 can partially or completely pass through the liquid inlet pipe 500, and the signal collector 220 can receive the light emitted from the liquid inlet pipe 500. Considering the refraction of light, the collection position of the signal collector 220 can be slightly offset to accurately receive the light emitted from the liquid inlet pipe 500.
