Preferably, the detachable device includes mounting posts 5 on both sides of the flat base 1 and the cover 3. Each mounting post 5 has mounting holes 6, and connecting plugs 7 are installed in the two mounting holes 6. To ensure stability, each side of the flat base 1 has at least two mounting posts 5, and similarly, each side of the cover 3 has at least two mounting posts 5. The number of mounting posts 5 on both sides of the cover 3 is the same as the number of mounting posts 5 on both sides of the flat base 1. During installation, the mounting posts 5 of both sides need to be aligned. Figure 1 As shown, mounting posts 1 (8) and 2 (9) are installed on each side of the flat base 1, and mounting posts 3 (10) and 4 (11) are installed on each side of the cover 3. During installation, mounting posts 1 (8) and 3 (10) are aligned, and mounting posts 2 (9) and 4 (11) are aligned. The connecting plug 7 includes a crossbar 12, with inserts 13 connected to both ends of the crossbar 12. The inserts 13 are integrally formed with the crossbar 12, and one side of the crossbar 12 and the inserts 13 are flat. During installation, the flat surface contacts the flat base 1 and the cover 3, and the inserts 13 are inserted into the mounting holes 6 of the mounting posts to connect the cover 3 and the flat base 1. The cross-sectional shape of the mounting holes 6 of the mounting posts is the same as that of the inserts 13, both being semi-circular with equal radii.

[0034] In this application, the air switch is installed inside the flat base 1, and then the cover 3 is installed. The flat base 1 provides a large operating space, which facilitates the installation and disassembly of the air switch. The cover 3 is connected to the flat base 1 by a detachable device, which improves stability and facilitates disassembly.

[0035] Example 2:

[0036] This embodiment describes the flat base 1 and the cover 3, specifically:

[0037] The flat base 1 includes a mounting plate 14, which is a flat plate. The mounting plate 14 has an air switch mounting hole 2 inside for mounting an air switch. A vertical plate 15 is provided on one side of the mounting plate 14 for rain protection. In this application, it is installed vertically with the vertical plate 15 located at the top. Furthermore, inclined plates 16 are provided on both sides of the vertical plate 15 to guide rainwater. A wiring plate 17 is provided on the side opposite to the vertical plate 15. The wiring plate 17 has wiring holes 18, through which the cable connected to the air switch is led out. Preferably, the mounting plate 14, the vertical plate 15, the inclined plate 16, and the wiring plate 17 are integrally formed.

[0038] The cover 3 includes a cover body 19, and a wiring hole mounting groove 20 is provided at the junction of the cover body 19 and the wiring plate 17. A vertical plate mounting groove 21 is provided on the side of the cover body 19 opposite to the wiring hole mounting groove 20. More specifically, the cover body 19 includes a cover side body 22, and a heat dissipation groove 4, a vertical plate mounting groove 21, and a wiring hole mounting groove 20 are provided on the cover side body 22. A flip cover 23 is rotatably installed on the top of the cover side body 22. The flip cover 23 can be easily opened to check the status of the air switch at any time.

[0039] During installation, the bottom of the cover body 19 contacts the upper surface of the flat base 1, aligning the two mounting columns 5. The connection can be achieved by inserting the connecting plug 7 into the mounting hole 6 of the mounting column, which is very simple and convenient. In this embodiment, when the installation is completed, there is a gap between the cover body 19 with the vertical plate mounting groove 21 and the vertical plate 15, which can further play a role in heat dissipation.

[0040] Furthermore, in order to better realize the installation of the flat base 1 and the cover 3, the edge of the flat base 1 is provided with a first stop 24 and a second stop 25, and the space between the first stop 24 and the second stop 25 is the cover mounting groove 26; the bottom of the cover side body 22 is provided with a cover mounting plate 27 that cooperates with the cover mounting groove 26; the cover mounting plate 27 is inserted into the cover mounting groove 26, making the connection between the flat base 1 and the cover 3 more stable.

[0041] Example 3:

[0042] This embodiment can improve the service life of the air switch. A fan is provided on the top of the cover 3 and / or a side fan is provided on the side wall of the cover 3. More specifically:

[0043] The flip cover 23 has mounting holes 28, and a fan is installed in the mounting holes 28. The fan can better dissipate heat from the air switch, reduce the probability of burnout, and thus improve the service life of the air switch. More preferably, the side mounting holes 29 are provided on both sides of the cover side body 22, and a side fan is installed in the side mounting holes 29. The arrangement of multiple fans can better dissipate heat.

[0044] A temperature sensor (not shown in the figure) is installed on the flat base 1 to monitor the temperature of the air switch.

The controller can be installed inside the display device 30 or in other locations. Technicians can make corresponding settings according to specific circumstances. The controller is connected to the fan and the side fan. The maximum and minimum temperatures of the air switch are preset in the controller. The temperature sensor monitors the temperature of the air switch in real time, displays it through the display device 30, and transmits it to the controller. When the temperature exceeds the preset maximum temperature, the controller controls the fan and / or the side fan to start to dissipate heat from the air switch. When the preset minimum temperature is reached, the controller controls the fan and / or the side fan to turn off. The gap between one side of the cover body 19 of the above-mentioned vertical plate mounting groove 21 and the vertical plate 15 can be used to observe the display device 30, thereby allowing the real-time temperature of the air switch to be known.

[0045] Preferably, to protect the fan and for aesthetic purposes, a protective device 31 is connected to the side mounting hole 29; an identification device 32 is connected to the outside of the mounting hole 28; specifically, the protective device 31 includes a protective base 33 installed in the side mounting hole 29, a protective base snap-fit ​​part is provided on the protective base 33, and a protective cover 34 is rotatably mounted on the protective base 33 to cooperate with it, and a protective cover snap-fit ​​part is provided on the protective cover 34 to cooperate with the protective base snap-fit ​​part, so that the protective cover 34 can be installed and removed by rotation; in order to better dissipate heat from the side fan, a protective cover heat dissipation groove 35 is provided on the protective cover 34; the side fan can be installed in the side mounting hole 29 or at the bottom of the protective base 33, depending on the specific situation. When both the protective base 33 and the side fan are installed in the side mounting hole 29, it is sufficient to ensure that the length of the side mounting hole 29 is sufficient to install both, that is, to select a cover side body 22 of appropriate thickness.

[0046] The marking device 32 includes a marking base 36 installed in a mounting hole 28. A fan can be installed on the marking base 36 or in the mounting hole 28, depending on the specific situation. When both are installed in the mounting hole 28, ensure the length of the mounting hole 28 is sufficient to accommodate both, i.e., select a flip cover 23 of appropriate thickness. A marking mounting groove 37 is provided in the middle of the marking base 36, and base locking parts 38 are symmetrically arranged at the edges of the marking mounting groove 37. A marking disc 39 is installed in the marking mounting groove 37. 9 includes a sign mounting part 40, a rotating part 41 is provided at the lower part of the sign mounting part 40, and a sign snap-fit ​​part 42 is provided on the rotating part 41 to cooperate with the base snap-fit ​​part 38.
