[0018] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0019] Please refer to Figure 1 , Figure 2 as well as Figure 3 , Figure 1 This is a schematic diagram of the overall structure of the airflow sensor module structure of the electronic atomizer provided by the utility model; Figure 2 A schematic diagram of the disassembled structure of the airflow sensor module structure of the electronic atomizer provided by the utility model; Figure 3 This is a schematic cross-sectional structural diagram of a placement cylinder and a guide cylinder provided by the utility model.

[0020] In the specific implementation process, Figures 1 to 3As shown, the airflow sensor module structure of the electronic atomizer provided by the utility model includes a circuit board 1 and a shell, the shell includes a placement cylinder 2 and a guide cylinder 3 coaxially fixedly connected, which enhances the overall strength and sealing performance and prevents the invasion of external pollutants. The cylinder structure is conducive to smooth airflow and reduces resistance. The placement cylinder 2 and the guide cylinder 3 are shells made of shielding material. A guide cavity 4 is arranged in the guide cylinder 3. The circuit board 1 is placed on the inner wall of the placement cylinder 2, and the circuit board 1 extends into the guide cavity 4 of the guide cylinder 3. The circuit board 1 extends into the guide cavity 4, shortening the sensing path, improving the response speed, reducing signal delay, and ensuring precise control. The guide cylinder 3 is away from the end of the placement cylinder 2 and is equidistantly provided with a plurality of straight guide holes 5 in the vertical direction, and the cross-sectional dimensions of the plurality of carton guide holes from the guide cavity 4 to the outside are expanding. The guide cylinder 3 is located outside the plurality of straight guide holes 5 and is also provided with a plurality of oblique guide holes 6, and the oblique guide holes 6 are inclined to the outer edge position of the guide cylinder 3.

[0021] The hot air generated by the operation of the circuit board 1 is transmitted to the guide cavity 4. By setting the straight guide hole 5, the straight guide hole 5 tends to expand so that the space for the exchange of cold and hot air is increased, the air flow speed is increased, and the sensitivity of the sensor is improved. The oblique guide hole 6 is set at an angle to guide the airflow at the inner edge of the guide cavity 4, increase the airflow sweeping area, optimize the airflow efficiency, reduce the range of dead angles, reduce the accumulation of dust, and maintain the sensitivity of the sensor.

[0022] An annular guide block 7 is fixedly connected to the edge of the inner wall of the guide cylinder 3 near the oblique guide hole 6. The annular guide block 7 is inclined from the side wall of the guide cylinder 3 to the oblique guide hole 6. The annular guide block 7 optimizes the airflow path of the guide cavity 4, ensures uniform airflow, reduces turbulence, and improves the sensor response speed. The circuit board 1 is placed on the side wall to facilitate heat dissipation and protection.

[0023] A plurality of reinforcing rings 8 are fixedly connected to the outer side of the guide cylinder 3 at the position of the straight guide hole 5. The reinforcing rings 8 are enlarged on the inside. The reinforcing rings 8 are gradually enlarged toward the inside of the guide cylinder, which more effectively improves the structural strength and stability, ensuring that the area around the guide hole will not be damaged due to pressure or vibration when the airflow passes through. At the same time, such a design helps to disperse stress, reduce local stress concentration, and extend service life. The airflow path is optimized to ensure the stability of the sensor and the accuracy of the response, while improving the durability in long-term use.

[0024] The inner wall of the placement cylinder 2 is provided with a sealing ring 9, and the two ends of the sealing ring 9 are respectively in close contact with the circuit board 1 and the inner wall of the placement cylinder 2. The existence of the sealing ring 9 is to ensure that the airflow will not leak during the flow inside the guide cylinder, and at the same time prevent external pollutants or moisture and dust from entering, and protect the internal circuit board 1 and the sensor from external interference. The sealing rings 9 at both ends are in close contact with the circuit board 1 and the inner wall of the placement cylinder 2. This design ensures the closedness of the entire system, which is not only more stable in structure, but also enhances the adaptability to the environment. The sealing ring 9 is arranged in an annular shape, and the material of the sealing ring 9 is polytetrafluoroethylene.
