2. The simple assembled wind pressure difference sensor according to claim 1, characterized by: The sleeve (4) corresponds one-to-one with the boss (11). The height of the boss (11) is greater than the thickness of the PCB board (3), so that the sleeve (4) can be fitted onto the boss (11). The long screw (22) passes through the sleeve (4).

3. The simple assembled wind pressure difference sensor according to claim 1, characterized by: The bottom shell (1) has a first assembly groove (12) on its side wall, which extends to the top of the bottom shell (1). The upper shell (2) has a second assembly groove (23) on its side wall, and the first assembly groove (12) and the second assembly groove (23) correspond one-to-one.

4. The simple assembled wind pressure difference sensor according to claim 1, characterized by: The external component (5) includes a high-voltage connector (51), a low-voltage connector (52), and an electrical output connector (53). The bottom shell (1) is provided with a high-voltage interface (13), a low-voltage interface (14), and an electrical output port (15). The high-voltage interface (13), the low-voltage interface (14), and the electrical output port (15) are respectively used to connect the high-voltage connector (51), the low-voltage connector (52), and the electrical output connector (53). The high-voltage connector (51), the low-voltage connector (52), and the electrical output connector (53) are located on the same side of the bottom shell (1).

5. The simple assembled wind pressure difference sensor according to claim 1, characterized by: The sleeve (4) is a flexible tube with an elastic margin.

6. The simple-to-assemble wind pressure difference sensor according to claim 1, characterized by: The boss (11) is provided in four parts, and the four bosses (11) are respectively located near the corners of the bottom shell (1).

7. The simple assembled wind pressure difference sensor according to claim 1, characterized by: The bottom shell (1) is provided with a mounting groove (16), which is directly opposite the electronic device mounting area of ​​the PCB board (3).

8. The simple assembled wind pressure difference sensor according to claim 1, characterized by: The bottom shell (1) has a stepped annular groove (17) along the contour direction of its inner sidewall, and the upper shell (2) is located in the stepped annular groove (17).
