A detachable display screen 4 is arranged on the right side of the partition 3, and a plexiglass 5 is fixed on the right side of the shell 1. A heating component 6 is arranged inside the shell 1. The heating component 6 includes a heating tube 601 fixed at the lower end of the shell 1, an exhaust fan 602 is fixed at the upper left end of the outer wall of the shell 1, and an exhaust pipe 603 arranged on the left side of the shell 1 is fixedly passed through the support plate 2. A clearance hole 604 is integrally provided at the upper left end of the shell 1, and an exhaust hole 605 is integrally provided on the right side of the support plate 2 at the lower end. A temperature sensor 606 is fixed on the right side of the bottom of the upper support plate 2, and a connector 607 is fixedly passed through the upper right end of the shell 1.

[0029] When the temperature at the display screen area is lower than the value monitored by the temperature sensor 606, the heating tube 601 and the exhaust fan 602 are turned on, and the exhaust fan 602 discharges the outside air from the hole 604 through the exhaust pipe 603 into the heating tube 601, so that the heating tube 601 heats the air discharged into the lower end of the shell 1, and the heated air is discharged into the display screen 4 through the exhaust hole 605, so that the hot air heats the display screen 4, and the hot air discharged into the display screen is discharged to the outside through the connector 607. When the temperature at the display screen 4 area is higher than the value set by the temperature sensor 606, the exhaust fan 602 and the heating tube 601 stop working.

[0030] Example 2

[0031] like Figure 1 , Figure 3 , Figure 4 , Figure 5As shown, a waterproof breathable membrane 7 is fixedly provided at the lower end of the exhaust pipe 603, a one-way valve 8 is fixedly connected to the exhaust pipe 603, a mounting pipe 9 is fixedly passed through the lower end of the left side of the exhaust pipe 603, one end of the mounting pipe 9 away from the exhaust pipe 603 is fixedly passed through the left side of the shell 1, the mounting pipe 9 is arranged at the upper end of the waterproof breathable membrane 7, a retaining net 10 is fixedly provided at the left side of the mounting pipe 9, a sealing plate 11 is hinged on the left side of the front end of the shell 1 and a password lock is provided on the right side, a controller 12 is fixedly provided inside the sealing plate 11, a mounting block 13 is fixedly provided inside the connector 607, a sliding pin 14 is slidably connected inside the mounting block 13, and the sliding pin 14 is slidably connected inside the mounting block 13. A mounting hole 15 is integrally provided inside, a slider 16 made of rubber material is fixedly provided on the right side of the sliding pin 14, the slider 16 is slidingly connected to the connecting head 607, a special-shaped hole 17 is integrally provided inside the slider 16, the special-shaped hole 17 is designed in a T-shape, the inside of the special-shaped hole 17 and the inside of the mounting hole 15 are in a connected design state, a spring 18 is sleeved on the right side of the outside of the sliding pin 14, the left side of the spring 18 is fixedly connected to the mounting block 13, and the right side of the spring 18 is fixedly connected to the slider 16, a baffle 19 is fixedly provided on the upper end of the right side of the outside of the shell 1, the baffle 19 is arranged at the upper end of the connecting head 607, and the baffle 19 and the connecting head 607 are in a parallel design state.

[0032] When rainwater is discharged into the exhaust pipe 603 through the clearance hole 604, the waterproof breathable membrane 7 blocks the rainwater to prevent it from contacting the heating tube 601. Gas can pass through the waterproof breathable membrane 7. The blocked rainwater is discharged to the outside through the installation tube 9. The blocking net 10 can prevent foreign matter from entering the exhaust pipe 603 through the installation tube 9. In addition, when hot air is discharged into the display screen 4 area, the slider 16 blocks the hot air. At this time, the air pressure at the display screen 4 will gradually rise, thereby extending the contact time between the hot air and the display screen 4 and improving the efficiency of the hot air in transferring heat. The effect transmitted to the display screen 4 is that when the air pressure in the display screen 4 area is high, at this time, the high-pressure hot air pushes the slider 16 and the sliding pin 14 to move to the right along the direction of the connecting head 607, so that the special-shaped hole 17 at the slider 16 moves out of the connecting head 607, and then the high-pressure gas in the display screen 4 area is discharged to the outside through the special-shaped hole 17 from the mounting hole 15. Through the rebound force of the spring 18, the slider 16 drives the sliding pin 14 to return to its original position, and the baffle 19 can prevent rainwater from being discharged into the shell 1 through the mounting hole 15 from the special-shaped hole 17.
