DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present utility model will be further described below with reference to the drawings and embodiments.

[0021] Please refer to Figures 1-4 wherein, Figure 1 is a schematic structural diagram of an airflow sensor module and an electronic atomization device provided by the present utility model; Figure 2 is Figure 1 a schematic structural diagram of the airflow sensor module shown in Figure 3 is Figure 2 a bottom view of the airflow sensor module shown in Figure 4 is Figure 3 a schematic structural diagram of the sensor body shown in Figure 5 is Figure 4 a schematic structural diagram of the elastic mechanism shown in

[0022] In a specific implementation process, as Figures 1-5 shown, an airflow sensor module includes a circuit board 8, a sensor body 2, and a positioning device 10. The sensor body 2 is located above the circuit board 8, and the positioning device 10 is fixedly arranged at the bottom of the sensor body 2;

[0023] The positioning device 10 includes a fixing block 3. Installation grooves 6 are formed on both sides of the fixing block 3. Elastic mechanisms 7 are fixedly installed in both installation grooves 6. The elastic mechanism 7 includes a telescopic rod 14 and an elastic member 12. The elastic member 12 is movably connected to the telescopic rod 14. One end of the telescopic rod 14 is fixedly connected to the inner top of the installation groove 6. The other end of the telescopic rod 14 is fixedly connected with a limiting block 4. The installation groove 6 is used to accommodate the limiting block 4. When the limiting block 4 is squeezed into the installation groove 6, the elastic member 12 contracts inward under pressure, and the telescopic rod 14 will expand and contract due to the contraction of the elastic member 12, enabling the limiting block 4 to enter the installation groove 6, so as to be able to perform the next operation. A through groove 9 is formed on the circuit board 8, and the through groove 9 is adapted to the fixing block 3, and the fixing block 3 can extend into the through groove 9.

[0024] Insertion pins are formed on the circuit board 8, and installation holes are formed at the bottom of the sensor body 2. When the fixing block 3 is aligned with the through groove 9, the insertion pins correspond to the installation holes. Therefore, when assembling the sensor body 2, it is only necessary to align the fixing block 3 with the through groove 9 to align the insertion pins with the installation holes.

[0025] The telescopic rod 14 includes a cylinder base 11 and a movable column 13. The movable column 13 is movably connected within the cylinder base 11, and the movable column 13 can expand and contract within the cylinder base 11. The elastic member 12 is a spring, and both ends of the elastic member 12 are fixedly connected to both ends of the telescopic rod 14. The contraction of the elastic member 12 can drive the movable column 13 to move within the cylinder base 11.

[0026] A plurality of heat dissipation fins 5 are fixedly installed at the bottom of the fixed block 3 and the bottom of the limit block 4. Both the fixed block 3 and the limit block 4 are made of graphene, and the heat conduction effect of graphene is very good. The heat generated by the sensor body 2 or even the circuit board 8 is conducted to the heat dissipation fins 5 at the bottom of the fixed block 3 and the limit block 4, and the generated heat is dissipated.

[0027] The installation grooves 6 are respectively located at both ends of the fixed block 3. The sum of the lengths of the two installation grooves 6 is less than the length of the fixed block 3, and the sum of the length of the cylinder base 11 and the width of the limit block 4 is less than or equal to the width of the fixed block 3, so that the limit block 4 can completely extend into the installation groove 6.

[0028] An electronic atomization device includes a housing 1 and an airflow sensor module as described in the above technical solution. The circuit board 8 is installed in the housing 1.

[0029] The working principle provided by the present utility model is as follows: When installing the airflow sensor module, the limit block 4 is squeezed into the installation groove 6, the elastic member 12 contracts inward under pressure, and the movable column 13 also moves inward into the cylinder base 11 until the limit block 4 completely enters the installation groove 6. Align the fixed block 3 with the through groove 9 on the circuit board 8 and move it downward. Release the pressing on the limit block 4. When the bottom of the sensor body 2 is in close contact with the top of the circuit board 8, the limit block 4 also reaches the bottom of the circuit board 8. The limit block 4 is no longer squeezed by the inner side wall of the through groove 9, and the limiting member returns to its original state outward, driving the movable column 13 to move outward in the cylinder base 11, achieving the effect of limiting the sensor body 2. Since the fixed block 3 and the limit block 4 are made of graphene, the heat conduction effect is very good. The heat generated by the sensor body 2 or even the circuit board 8 is conducted to the heat dissipation fins 5 at the bottom of the fixed block 3 and the limit block 4, and the generated heat is dissipated.

[0030] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated here.

[0031] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
