[0038] Please refer to the attached Figures 1 to 4 In the present application, base 10 serves as the supporting component of anti-tamper mechanism 100, supporting housing 20 and the electronic control module. Base 10 includes a connecting portion 11 for connecting to an external device under test. This allows base 10 to connect to the external device under test via connecting portion 11, thereby facilitating the securement of anti-tamper mechanism 100 to the external device under test via base 10. Base 10 also includes a boss 12, which projects upward from base 10.

[0039] Please refer to the attached Figures 1 to 3 5. In the implementation of this application, the housing 20 is disposed on the upper side of the base 10; the housing 20 is provided with a receiving groove 20a, which serves as the internal space of the housing 20 and is used to accommodate the electronic control module and the boss 12; so that the electronic control module and the boss 12 can be accommodated inside the housing 20 through the receiving groove 20a. The boss 12 passes through the receiving groove 20a and is built into the housing 20; the outer wall of the boss 12 is engaged with the inner wall of the housing 20 and serves as an anti-disassembly structure; the anti-disassembly structure is located within the housing 20 and is covered by the housing 20, preventing the anti-disassembly structure from being exposed to the external environment and inconvenient for users to disassemble, thereby realizing the anti-disassembly design of the base 10 and the housing 20, and ensuring the effectiveness of the air pressure sensor through the anti-disassembly mechanism 100.

[0040] Please refer to the attached Figures 1 to 3A first engaging member 121 and a second engaging member 22 are provided between the outer wall of the boss 12 and the inner wall of the shell 20; the first engaging member 121 and the second engaging member 22 are engaged and connected to form an anti-dismantling structure, so that the shell 20 can be engaged and connected with the boss 12 through the cooperation of the first engaging member 121 and the second engaging member 22, so that the shell 20 is covered with the anti-dismantling structure, and then the anti-dismantling structure is hidden on the inner side of the shell 20, avoiding the anti-dismantling structure from being exposed to the external environment, making it inconvenient for users to disassemble, realizing the anti-dismantling design of the base 10 and the shell 20, and ensuring the use effect of the air pressure sensor through the anti-dismantling mechanism 100.

[0041] Please refer to the attached Figures 1 to 3 The outer wall of the boss 12 is provided with a first engaging member 121, which protrudes outward from the outer wall of the boss 12. The inner wall of the housing 20 is provided with a second engaging member 22, which is recessed inward from the inner wall of the housing 20. The outer contour of the first engaging member 121 matches the inner contour of the second engaging member 22. When the boss 12 is accommodated in the accommodating groove 20a, the first engaging member 121 and the second engaging member 22 are engaged and connected, so that the housing 20 covers the first and second engaging members 121 and 22, preventing them from being exposed to the external environment and making it difficult for users to disassemble them. This implements the anti-dismantling design of the base 10 and the housing 20, and ensures the effective use of the air pressure sensor through the anti-dismantling mechanism 100. Optionally, the first engaging member 121 is a locking arm and the second engaging member 22 is a locking groove.

[0042] Please refer to the attached Figures 1 to 4 The outer wall of the boss 12 is arranged in a ring shape, and corresponding first engaging members 121 are provided in each direction; the first engaging members 121 are arranged correspondingly to the second engaging members 22. By arranging multiple first engaging members 121, the connection stability between the boss 12 and the shell 20 is increased, and the connection strength between the base 10 and the shell 20 is improved.

[0043] Please refer to the attached Figures 1 to 3 The boss 12 is inserted into the receiving groove 20a and positioned and connected with the receiving groove 20a, ensuring the position accuracy between the boss 12 and the receiving groove 20a, thereby facilitating the first engaging member 121 to align with the second engaging member 22 for engagement connection, thereby avoiding the first engaging member 121 and the second engaging member 22 from being staggered.

[0044] Please refer to the attached Figure 3The notch of the accommodating groove 20a faces downward, and the boss 12 enters the accommodating groove 20a from bottom to top. The inner wall of the accommodating groove 20a squeezes the first engaging member 121. When the first engaging member 121 is aligned with the second engaging member 22, the first engaging member 121 is reset under the action of elasticity, so that the first engaging member 121 and the second engaging member 22 are engaged with each other, so that the first engaging member 121 and the second engaging member 22 are both on the inner side of the shell 20, avoiding the first engaging member 121 and the second engaging member 22 from being exposed to the external environment, making it inconvenient for users to disassemble, realizing the anti-dismantling design of the base 10 and the shell 20, and ensuring the use effect of the air pressure sensor through the anti-dismantling mechanism 100.

Heat dissipation holes 20a communicate with receiving slot 20a, allowing receiving slot 20a to communicate with the external environment through heat dissipation holes 20a. Heat dissipation holes 20a are arranged relative to the electronic control module so that heat generated by the electronic control module flows through receiving slot 20a and heat dissipation holes 20a to the external environment. Heat generated by the electronic control module is discharged outward through heat dissipation holes 20a, thereby dissipating heat from the electronic control module and ensuring its performance. Optionally, heat dissipation holes 20a are louver-shaped.

[0046] Please refer to the attached Figure 1 The shell 20 is provided with a display surface 23, which is located on the upper surface of the shell 20.
