[0031] A protective mechanism is provided on the inner wall of the cabinet body 1. The protective mechanism includes a first shock-absorbing component and a second shock-absorbing component. The first shock-absorbing component includes a mounting plate 8 slidably connected to the inner wall of the cabinet body 1. A plurality of dampers 9 are fixedly connected to the bottom of the mounting plate 8. A first spring 10 is sleeved on each of the plurality of dampers 9. The bottoms of the plurality of dampers 9 are fixedly connected to a support plate 11. The second shock-absorbing component includes two first support blocks 12 fixedly connected to the bottom of the mounting plate 8. A first connecting plate 13 is rotatably connected to the bottom of each of the first support blocks 12. A sliding rod 14 is fixedly connected to the inner wall of the cabinet body 1. Two sliders 15 are slidably connected to the sliding rod 14. One end of each of the two first connecting plates 13 close to the sliding rod 14 is rotatably connected to the corresponding slider 15. A second spring 16 is fixedly connected between the two sliders 15. The protective mechanism includes an adjusting component. The adjusting component includes a bidirectional threaded rod 17 rotatably connected to the inner wall of the cabinet body 1. The left end of the bidirectional threaded rod 17 extends to the outside of the cabinet body 1. Two internally threaded blocks 18 are threadedly connected to the bidirectional threaded rod 17. A second connecting plate 19 is fixedly connected to the top of each of the two internally threaded blocks 18. A second support block 20 is fixedly connected to one end of each of the two second connecting plates 19 close to the support plate 11. The tops of the two second support blocks 20 are fixedly connected to the bottom of the support plate 11. A crank 21 is fixedly connected to the left end of the bidirectional threaded rod 17. A top plate 22 is fixedly connected to the inner wall of the cabinet body 1. An electric heater 23 is provided between the top plate 22 and the mounting plate 8. Through the protective mechanism, the electric heater inside the cabinet can be effectively shock-absorbed, avoiding the possibility of damage to the electric heater 23 caused by the vibration generated during the movement of the device. At the same time, for the adjusting component, the top and bottom of the electric heater 23 can be respectively in contact with the top plate 22 and the mounting plate 8 to form a clamping effect on the electric heater 23, strengthening the stability of the electric heater 23.

[0032] An auxiliary mechanism is provided inside the cabinet body 1. The auxiliary mechanism includes an exhaust component. The exhaust component includes exhaust fans 24 fixedly connected to the top, left and right sides of the cabinet body 1. The auxiliary mechanism includes a waterproof component. The waterproof component includes a filter screen 25 fixedly connected to the right end of the air inlet 4. A drying plate 26 is slidably connected to the inner wall of the air inlet 4. A rain shield 27 is provided on the top of the cabinet body 1. A base 28 is fixedly connected to the bottom of the cabinet body 1. A plurality of universal wheels 29 are fixedly connected to the bottom of the base 28. Through the auxiliary mechanism, the rain shield 27 makes the outer shell of the cabinet body 1 waterproof in rainy weather. At the same time, the filter screen 25 and the drying plate 26 can effectively prevent moisture and dampness from invading the inside of the cabinet body 1, avoiding the corrosion and damage of the components of the electric heater 23, thereby prolonging the service life of the electric heater. The exhaust fans 24 exhaust the air inside the cabinet body 1, making the air inside the cabinet body 1 circulate. The universal wheels facilitate the overall movement of the device and its use in different working environments.

[0033] A specific application of this embodiment is as follows: Start the fan 2. The fan 2 sucks the air outside the cabinet 1 from the air inlet 4 through the air suction pipe 3. When passing through the air inlet 4, the filter screen 25 and the drying plate 26 filter and dry the air entering the air inlet 4 to prevent dust particles and moisture in the air from entering the interior of the cabinet. The air absorbed by the fan 2 is sent into the air vortex cooler 6 through the air supply pipe 5 for cooling. The cooled air is then discharged into the interior of the cabinet through the exhaust pipe 7 to cool the electric heater 23 inside the cabinet. At the same time, the mounting plate 8, the support plate 11, and the top plate 22 are all hollow plates. When the electric heater is vibrated, the mounting plate 8 receives the pressure from the electric heater 23. The mounting plate 8 transmits the pressure to several dampers 9 below the mounting plate. The dampers 9 and the first spring 10 perform the first shock absorption on the electric heater 23. At the same time, under the pressure of the mounting plate 8, the first support block 12 drives the first connecting plate 13 to approach each other. While the two connecting plates approach each other, they drive the two sliders 15 to move on the slide rod 14. The two sliders 14 transmit the force to the second spring 16, thereby decomposing the impact force received by the first spring 10. When it is necessary to adjust the position and height of the mounting plate 8, rotate the crank 21. The crank 21 drives the bidirectional threaded rod 17 to rotate. The bidirectional threaded rod 17 drives the two internally threaded blocks 18 to approach or move away from each other. The two internally threaded blocks 18 drive the two second connecting plates 19 to move. While the second connecting plates 19 move, they adjust the support plate 11 up and down through the second support block 20. The support plate 11 and the mounting plate 8 are connected together as a whole through the damper 9. Thus, the mounting plate 8 moves along with the support plate 11. With the adjustment of the height of the mounting plate 8, the top of the electric heater 23 on the mounting plate 8 comes into contact with the top plate 22, thereby clamping the electric heater 23 and providing further protection for the electric heater 23. The exhaust fan 24 discharges the air inside the cabinet 1, enabling the air inside the cabinet 1 to circulate. When it is rainy, the rain shield 28 can make the outer wall of the cabinet 1 waterproof. The base 28 raises the overall height of the cabinet 1 to prevent the bottom of the cabinet 1 from contacting the ground, thereby avoiding the risk of water entering the interior of the cabinet 1 when the bottom of the cabinet 1 contacts the rainwater on the ground during rainy days. The universal wheels 29 facilitate the overall movement of the device and its use in different working environments.
