A dustproof ventilation component 2 is fixedly connected inside the bottom shell 11, which is used to change the airflow path inside the device and reduce the entry of dust into the device to affect the device. The dustproof ventilation component 2 includes a ventilation bracket 21, a rear support plate 22, a ventilation pressure plate 23, and a front support plate 24. The ventilation bracket 21 is fixedly connected to the bottom of the inner wall of the bottom shell 11. The ventilation bracket 21 includes a bracket seat 211, which is used to change the direction of airflow entering the device and assist in fixing the air detector. The bottom of the bracket seat 211 is fixedly connected to the bottom of the inner wall of the bottom shell 11.

The circuit module 31 includes a chipset and a battery pack for monitoring and controlling the remaining mechanisms of the active dust removal component 3. The circuit module 31 is fixedly connected to the bottom of the inner wall of the bottom shell 11, and the circuit module 31 is located inside the circuit cover 15. A temperature sensor 32 is fixedly connected to the bottom of the inner wall of the bottom shell 11 for sensing the temperature in the device and transmitting a feedback signal to the circuit module 31. The temperature sensor 32 is located on the front of the circuit cover 15, and the back of the temperature sensor 32 is electrically connected to the circuit module 31 through a wire; A vibration assembly 33 is fixedly connected to the bottom of the inner wall of the bottom shell 11, which is used to generate vibration to assist dust removal and reduce the probability of dust blocking the device affecting the air detector. The vibration assembly 33 includes a bottom plate 331, the bottom of the bottom plate 331 is fixedly connected to the bottom of the inner wall of the bottom shell 11, and the top of the bottom plate 331 is fixedly connected to a vibration motor group 332. The vibration motor group 332 includes a motor and an eccentric wheel fixed on the motor shaft, which is used to generate vibration by rotating the eccentric wheel. An eccentric wheel sheath is fixedly connected to the top of the bottom plate 331, which is used to protect the eccentric wheel from other mechanisms and contact the vibration bridge 341. The eccentric wheel sheath is located outside the eccentric wheel. A limiting plate 333 is fixedly connected to the front of the bottom plate 331, which is used to limit the sliding range of the vibration bridge 341 and transmit vibration. The back of the vibration motor group 332 is electrically connected to one side of the circuit module 31 through a wire. The rectangular hole on one side of the ventilation bracket 21 is slidably connected with a vibrating clearing plate 34, which is used to clean the dust in the ventilation bracket 21 with the cooperation of the vibration component 33, thereby reducing the probability of dust blocking the device. The vibrating clearing plate 34 includes a vibration bridge 341, which is used to connect the bristle brush plate 342 and contact the limit plate 333 and the eccentric wheel sleeve at the same time.

The minimum distance is zero millimeter and the maximum distance is one millimeter. The back side of the vibration bridge 341 is adjacent to the back side of the limiting plate 333. The minimum distance is zero millimeter and the maximum distance is one millimeter.

[0023] During use, when the temperature sensor 32 detects that the internal temperature of the device exceeds the normal operating temperature of the air detector and continues to rise, a feedback signal is sent to the chipset of the circuit module 31. After receiving the feedback signal, the chipset determines that it is blocked by dust, and the chipset controls the vibration motor group 332 to start. The motor of the vibration motor group 332 drives the eccentric wheel to rotate, and the rotation of the eccentric wheel generates vibration. The vibration is transmitted to the vibration bridge 341 through the eccentric wheel sheath and the limit plate. The vibration bridge 341 moves slightly back and forth under the action of vibration, and transmits the vibration to the bristle brush plate 342. The bristle brush of the bristle brush plate 342 moves slightly back and forth under the drive of the vibration bridge 341, scrapes off the dust inside the ventilation bracket 21 and on the surface of the circular hole mesh, and at the same time, the bristle brush transmits the vibration to the inside of the ventilation bracket 21 and the bottom of the bottom shell 11, and cleans the dust blockage with the help of vibration.

[0024] For example 3, please refer to Figure 1-9Based on the first and second embodiments, the present invention provides a technical solution: An exhaust fan 35 is fixedly connected to the back of the bottom shell 11 through a rectangular through hole, a dustproof net 351 is fixedly connected to the back of the exhaust fan 35, the front of the exhaust fan 35 is electrically connected to one side of the circuit module 31 through a wire, a cooling auxiliary component 36 is fixedly connected to the bottom of the inner wall of the bottom shell 11, and the cooling auxiliary component 36 includes a heat conducting plate 364, the heat conducting plate 364 is fixedly connected to the bottom of the inner wall of the bottom shell 11 through the rectangular through hole at the bottom of the bottom shell 11, a semiconductor refrigerator 361 is fixedly connected to the top of the heat conducting plate 364, the top of the semiconductor refrigerator 361 is a cooling end, and the bottom of the semiconductor refrigerator 361 is a heating end, and a cold fin 363 is fixedly connected to the top of the semiconductor refrigerator 361 for increasing the contact area between the air and the cooling end, thereby promoting the cooling of the air in the device, and a wiring terminal 362 is fixedly connected to the back of the semiconductor refrigerator 361, and the back of the wiring terminal 362 is electrically connected to the front of the circuit module 31 through a wire; An expansion tube 365 is fixedly connected to the bottom of the heat conducting plate 364, which is used to deform and support the entire device under the compression of hot air. One side of the expansion tube 365 is connected to a rectangular through hole, and one side of the expansion tube 365 is connected to an expansion pad 366. The expansion pad 366 is made of elastic material, and the inside of the expansion pad 366 is connected to a rectangular through hole. The top cross-section of the expansion pad 366 is C-shaped, and the top of the expansion pad 366 is fixedly connected to the bottom of the bottom shell 11.

[0025] When in use, when the device is placed flat on the ground or other surfaces, when the temperature sensor 32 detects that the temperature inside the device exceeds the normal operating temperature of the air detector, the temperature sensor 32 sends a feedback signal to the chipset of the circuit module 31. The chipset of the circuit module 31 determines that it is high temperature, and then starts the exhaust fan 35 and the semiconductor refrigerator 361. After the semiconductor refrigerator 361 is started, the cooling end starts to cool. The cooling end absorbs the heat of the air in the device through the cold fins 363 to cool the air in the device. At the same time, the exhaust fan 35 rotates to remove the hot air in the device and drives the low-temperature air that has exchanged heat with the cold fins 363 to flow, thereby reducing the temperature level of the air in the device. When the cooling end starts cooling, the heating end starts heating. The heat is transferred to the inside of the expansion tube 365 through the heat conducting plate 364. The volume of the air inside the expansion tube 365 increases after being heated. At the same time, the heat is transferred to the air inside the expansion pad 366. Then, the volume of the air inside the expansion tube 365 and the expansion pad 366 increases, squeezing the expansion pad 366 to cause elastic deformation. The expansion pad 366 and the air inside the expansion pad 366 support the entire device together, raising the height between the circular hole net at the bottom of the bottom shell 11 and the contact surface, thereby helping to promote air flow and reduce the dust on the contact surface and the blockage of the device by dust; When the temperature sensor 32 detects that the internal temperature of the device exceeds the normal operating temperature of the air detector and continues to rise, while the device executes the process provided in the aforementioned embodiment 2, the exhaust fan 35 cooperates with the vibrating cleaning plate 34 to discharge the cleaned dust, thereby improving the heat dissipation performance of the device.
