[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 5 This embodiment provides a modular cabin temperature control system, including a shell 1, an air inlet 2 and an air outlet 3 on the shell 1, the air inlet 2, the inner cavity of the shell 1 and the air outlet 3 are connected in sequence, and also includes a filter screen 4, which is set at the air inlet 2, and an exhaust fan 5 is installed at the air outlet 3 of the shell 1.

[0024] By driving the exhaust fan 5 to work, a negative pressure is formed in the inner cavity of the housing 1, thereby drawing in outside air through the air inlet into the inner cavity of the housing 1 and then expelling it from the air outlet 3. The incoming air is filtered by the filter screen 4 to remove dust and impurities.

[0025] On the outer wall of the housing 1 near the filter screen 4, there are symmetrical sliding rods 6 on the left and right sides of the filter screen 4. The upper and lower ends of the sliding rods 6 are bent and extended towards the outer wall of the housing 1 and fixed to the outer wall of the housing 1. The upper and lower ends of the sliding rods 6 are fixed with baffles 7. The outer wall of the sliding rods 6 is slidably fitted with sliding sleeves 8. A plate 9 is fixed between two sliding sleeves 8. Several bristles 91 are fixed at equal intervals on the side of the plate 9 near the filter screen 4, and the ends of the bristles 91 abut against the surface of the filter screen 4.

[0026] By sliding the plate 9 up and down, the bristles 91 can sweep across the surface of the filter screen 4, thereby brushing away the dust on the surface of the filter screen 4 and achieving the effect of cleaning the filter screen 4.

[0027] A spring 10 is sleeved on the outer side of the lower end of the slide rod 6. The lower end of the spring 10 is in contact with the top surface of a baffle 7 at the lower end of the slide rod 6. The upper end of the spring 10 is in contact with the bottom surface of the slide sleeve 8. Under the action of the elastic force of the spring 10, the top surface of the slide sleeve 8 abuts against the surface of a baffle 7 at the upper end of the slide rod 6.

[0028] The entire device is installed on a vehicle-mounted container during use. When the vehicle moves, it generates significant vibrations, causing the plate 9 to overcome the elastic force of the spring 10 and slide downwards along the slide rod 6, compressing the spring 10 and completing one cleaning of the filter screen 4. After sliding to its limit, the spring 10 rebounds, and due to the reciprocating vibration of the vehicle, it also drives the plate 9 to slide upwards, cleaning the filter screen 4 again. By utilizing the continuous vibration during vehicle travel, the plate 9 is driven to slide up and down. No additional power equipment is needed to drive the cleaning structure, and no motor is required for cleaning, reducing the equipment's manufacturing and operating costs. No energy is required during operation.

[0029] Furthermore, during the cleaning process, the temperature control system does not work, and there is no negative pressure at the air inlet. After the bristles 91 clean the filter 4, under the action of the spring 10's rebound force and the vehicle's vibration, the slide sleeve 8 will hit the surface of a baffle 7 at the upper end of the slide rod 6 at the end of the slide. This generates vibration, which allows the dust on the bristles 91 to be shaken off and removed by the vehicle, further ensuring that the bristles 91 can always have a better cleaning effect and extending the time cycle for manual maintenance of the slide body 9 and the bristles 91.

[0030] A push-pull electromagnet 11 is fixed at one end of the plate 9. A stop block 12 is fixed at the upper end of the outer wall of the housing 1 near the push-pull electromagnet 11. When the top surface of the sliding sleeve 8 abuts against the surface of a stop plate 7 at the upper end of the sliding rod 6, the push-pull electromagnet 11 and the stop block 12 are directly opposite each other, and the protruding end of the push-pull electromagnet 11 rests on the top surface of the stop block 12.

[0031] When cleaning is not required and the vehicle is stationary, the spring force of the spring 10 keeps the plate 9 at its uppermost position. At this time, the extended end of the drive push-pull electromagnet 11 extends and abuts against the inclined surface of the top of the stop block 12, thereby limiting the plate 9. In this way, the plate 9 will not slide up and down during subsequent driving, thus not performing the limiting work. This improves the flexibility of the entire structure, allowing it to work or not work as needed, and also avoids the spring 10 being compressed for a long time, thus extending the service life of the spring 10.

[0032] A fence 13 is fixed on the outer wall of the housing 1 near the filter screen 4. The plate 9, slide rod 6, spring 10 and push-pull electromagnet 11 are all covered by the fence 13, which can protect the structure such as the plate 9.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
