The filter box is installed inside the heat dissipation holes, and a filter sheet is installed at the upper end of the filter box. A sealing sheet is installed at the upper end of the filter box, and a pipe connector is installed at the upper end of the sealing sheet.

[0006] Furthermore, the top surface of the switch box is provided with a movable groove, and an insulating plate is provided inside the movable groove.

[0013] This utility model provides a heat-resistant switch structure for high-temperature environments, which has the following beneficial effects: 1. This utility model provides a cooling channel for the switch box through two heat dissipation holes, which facilitates the dissipation of heat inside the switch box and reduces the internal temperature of the box. This allows the switch box to maintain a normal operating temperature inside the box when used in high-temperature environments.

The pipe connector is used to send the cooling gas into the interior of the switch box.

[0014] 2. In this utility model, the auxiliary plate moves in the auxiliary slot along with the switch plate, so that the movable slot is always sealed to prevent dust from entering the switch box.

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0018] like Figure 1 and Figure 2As shown, a heat-resistant switch structure for high-temperature environments includes a switch box 1 and a heat dissipation assembly 3. A switch plate 2 is provided on the top of the switch box 1. A lever 6 is connected to the lower end of an insulating plate 4. A stationary contact 7 is in contact with the left side of the lever 6, and a moving contact 8 is in contact with the right side of the lever 6. A line fixing hole 9 is provided at the upper end of the moving contact 8. A ceramic protective sleeve 10 is provided on the outside of the moving contact 8. The ceramic protective sleeve 10 plays a role in suppressing the connection arc at the moving contact 8. The ceramic protective sleeve 10 is U-shaped. An inner heat insulation layer 12 is provided on the outside of the switch box 1. The inner heat insulation layer 12 is made of glass fiber cotton, which is lightweight and has excellent heat insulation properties. An outer heat insulation layer 13 is provided on the outside of the inner heat insulation layer 12. The outer heat insulation layer 13 is made of alumina ceramic, which has strong insulation properties and is suitable for direct contact with high-temperature environments.

[0019] like Figure 2 As shown, the heat dissipation assembly 3 for heat dissipation is disposed at the upper and lower ends of the switch box 1. The heat dissipation assembly 3 includes heat dissipation holes 301, a filter box 302, a filter sheet 303, a sealing sheet 304, and a pipe connector 305. The filter box 302 is installed inside the heat dissipation holes 301. The two heat dissipation holes 301 provide a cooling channel for the switch box 1, facilitating the dissipation of heat inside the switch box 1 and reducing the internal temperature of the box. This ensures that the switch box 1 maintains a normal operating temperature inside the box even in high-temperature environments. The filter sheet 303 is installed at the upper end of the filter box 302. The filter box 302 and the filter sheet 303 provide a dual filtration effect for the cooling gas, ensuring the cleanliness of the switch box 1. The sealing sheet 304 is installed at the upper end of the filter box 302. A pipe connector 305 is installed at the upper end. The pipe connector 305 is used to send cooling gas into the interior of the switch box 1. A movable groove 11 is opened on the top surface of the switch box 1, and an insulating plate 4 is installed inside the movable groove 11. An auxiliary component 5 for auxiliary moving sealing is installed on the side of the insulating plate 4. There are two sets of auxiliary components 5. The auxiliary component 5 includes an auxiliary groove 501 and an auxiliary plate 502. The auxiliary plate 502 is installed inside the auxiliary groove 501. The auxiliary groove 501 and the auxiliary plate 502 are slidably connected. The auxiliary plate 502 moves in the auxiliary groove 501 as the switch plate 2 moves, so that the movable groove 11 is always sealed to prevent dust from entering the interior of the switch box 1. The size of the auxiliary plate 502 is larger than the size of the movable groove 11.

[0020] In summary, this heat-resistant switch structure for high-temperature environments is first based on... Figures 1-3As shown in the diagram, when the switch box 1 is in use, the lever 6 is moved by moving the switch plate 2. When the lever 6 contacts the moving contact 8, the circuit is connected; when the lever 6 contacts the stationary contact 7, the circuit is closed. In high-temperature environments, the pipe connector 305 is connected to the fan outlet. The fan, driven by a motor, rotates at high speed, pushing airflow in a directional direction to form an airflow that is delivered into the switch box 1. The two heat dissipation holes 301 provide cooling channels for the switch box 1, facilitating heat dissipation and reducing the internal temperature, thus enabling the switch box 1 to operate effectively in high-temperature environments. The internal temperature of the switch box is maintained, and the filter box 302 and filter sheet 303 provide dual filtration for the cooling gas, ensuring the cleanliness of the switch box 1. When the switch plate 2 moves, the auxiliary plate 502 moves in the auxiliary groove 501 along with the switch plate 2, keeping the movable groove 11 in a sealed state at all times to prevent dust from entering the switch box 1. The inner heat insulation layer 12 of the switch box 1 is made of glass fiber cotton, which is lightweight and has excellent heat insulation properties. The outer heat insulation layer 13 is made of alumina ceramic, which has strong insulation properties and is suitable for direct contact with high temperature environments.
