On the one hand, it cooperates with the air conditioner to adjust the temperature inside the vehicle, and on the other hand, it purifies the air inside the vehicle.

[0037] like Figure 1 ,2 As shown, an air pump 2 for pumping the air inside the vehicle into the pipe A1 is installed on the pipe A1.

[0038] As Figure 1 、 2 shown, a flow meter 3 for monitoring the air flow rate inside the pipe A1 is installed on the pipe A1.

[0039] As Figure 1 、 2 shown, a filtering device 42 for filtering the air inside it is installed on the pipe B41.

[0040] As Figure 2 、 4 shown, a circular baffle 45 that rotates around a horizontal axis inside the pipe C44 and is switched on and off under the drive of a motor B46 rotates inside the pipe C44.

[0041] As Figure 3 、 10 shown, the upper end of the rotating shaft C38 in the purification mechanism 20 has a hexagonal sleeve 40, the hexagonal sleeve 40 is matched with the hexagonal head at the lower end of the rotating shaft B10 inside the pipe A1, the gear C9 installed on the rotating shaft B10 meshes with the gear B8 on the rotating shaft A6 on the wall surface of the pipe A1, and the gear A7 on the rotating shaft A6 meshes with the gear D11 on the output shaft of the corresponding motor A13; teeth 18 are circumferentially densely arranged at the upper end of the ring sleeve F34 in the purification mechanism 20; as Figure 3 、 8 、10 shown, a ring sleeve A15 is rotatably fitted in a circular groove on the vehicle body 5, the toothed ring 14 installed on the ring sleeve A15 meshes with the gear E12 on the output shaft of the motor B46, a ring sleeve B17 slides vertically inside the ring sleeve A15 and a return spring 16 for resetting the ring sleeve B17 is installed, and the teeth 18 circumferentially densely arranged at the lower end of the ring sleeve B17 are matched with the teeth 18 on the ring sleeve F34 in the purification mechanism 20.

[0042] As Figure 3 、 4 、10 shown, the upper end of the rotating shaft C38 in the air supplementing mechanism 21 has a hexagonal sleeve 40, the hexagonal sleeve 40 is matched with the hexagonal head at the lower end of the rotating shaft B10 inside the pipe C44, the gear C9 installed on the rotating shaft B10 meshes with the gear B8 on the rotating shaft A6 on the wall surface of the pipe C44, and the gear A7 on the rotating shaft A6 meshes with the gear D11 on the output shaft of the corresponding motor A13; as Figure 3 、 8As shown in Figures 9 and 10, on the upper end circumference of the middle sleeve F34 in the air supplement mechanism 21, locking teeth 18 are densely arranged circumferentially; in the circular groove on the vehicle body 5, a middle sleeve A15 is rotatably fitted, and a gear ring 14 installed on the middle sleeve A15 meshes with a gear E12 on the output shaft of the motor B46. A middle sleeve B17 slides vertically in the middle sleeve A15, and a return spring 16 for resetting the middle sleeve B17 is installed. The locking teeth 18 densely arranged on the lower end circumference of the middle sleeve B17 cooperate with the locking teeth 18 on the middle sleeve F34 in the air supplement mechanism 21.

[0043] As Figure 3 , 9 、10, on the inner wall circumference of the cylinder A22, stoppers 25 corresponding one-to-one to the dust discharge grooves 31 on the corresponding ring plate B30 are densely arranged evenly circumferentially. Each stopper 25 has two inclined surfaces to prevent dust from staying thereon.

[0044] As Figure 2 , 6 、10, a middle sleeve G48 is installed in the cylinder B27 of the air supplement mechanism 21. In the middle sleeve G48, a heating pipe 49 arranged horizontally with multiple bends is installed. The two ends of the heating pipe 49 are respectively communicated with the inlet and outlet of the heat exchanger on the exhaust pipe; the cross-section of the heating pipe 49 is a quadrilateral with a small angle at the lower end and a large angle at the upper end.

[0045] As Figure 2 , 7 、10, the lower end of the cylinder B27 in the air supplement mechanism 21 is in threaded fit with a horn-shaped cylinder 50. Inside the lower end of the horn-shaped cylinder 50, a filter screen 51 for blocking large particles or garbage is installed.

[0046] As Figure 1 , 2 、10, the pipe A1 and the pipe B41 are fixed on the fixing seat 4 on the vehicle body 5, and the pipe C44 is fixed on the vehicle body 5.

[0047] As Figure 3 , 4 、10, the rotating shaft C38 in the air supplement mechanism 21 or the purification mechanism 20 rotates in two shaft sleeves 36 fixed to the middle sleeve E29 and the middle sleeve F34 through several connecting rods B37.

[0048] Workflow of the present invention: In the initial state, the stoppers 25 on the inner wall of the cylinder A22 in the purification mechanism 20 and the air supplement mechanism 21 close the corresponding dust discharge grooves 31 on the corresponding ring plate B30. The hexagonal sleeve 40 on the rotating shaft C38 is inserted into the hexagonal head on the corresponding rotating shaft B10. The locking teeth 18 on the middle sleeve B17 engage with the locking teeth 18 on the corresponding middle sleeve F34, and the return spring 16 is in a compressed state. The baffle 45 in the air supplement mechanism 21 is in a closed state with respect to the pipe C44.

[0049] When it is necessary to perform an internal air circulation inside the vehicle, the air pump 2 is started. The air pump 2 circulates the air inside the vehicle back into the vehicle through the pipe A1, the purification mechanism 20, the pipe B41, the filtering device 42, and the air conditioner heat exchanger 43. Since the air flow rate in the pipe A1 does not change because there is no air leakage, the flow value on the flow meter 3 remains unchanged, and the internal air circulation inside the vehicle continues.

[0050] When sand or dust enters the vehicle's air due to the vehicle's activities in sandy and dusty areas and it is necessary to purify and filter the air inside the vehicle, the air pump 2 and the motor A13 corresponding to the purification mechanism 20 are started. The air pump 2 circulates the air inside the vehicle back into the vehicle through the pipe A1, the purification mechanism 20, the pipe B41, the filtering device 42, and the air conditioner heat exchanger 43 for circulation. At the same time, the motor A13 corresponding to the purification mechanism 20 drives the rotating shaft C38 and the ring plate C33 in the purification mechanism 20 to rotate rapidly in opposite directions through a series of transmissions. The ring plate C33 drives all the corresponding blade plates A32 and the ring plate B30 to rotate synchronously. The dust discharge groove 31 on the ring plate B30 is quickly reciprocally opened and closed by the stopper 25 on the inner wall of the corresponding cylinder A22. The rotating shaft C38 in the purification mechanism 20 drives the air flowing vertically downward to rotate rapidly through the blade plates A32 on it, and basically does not leak from the gaps between the blade plates A32. A small part of the air collides with the blade plates A32 during the rotation process and is reflected back under the obstruction of all the corresponding blade plates A32 and moves downward with the majority of the air. Another small part of the air enters the cylinder A22 through the gaps between the blade plates A32 and is discharged when the dust discharge groove 31 on the ring plate B30 is opened.

[0051] Meanwhile, the sand or dust in the air entering between all the blade plates A32 in the purification mechanism 20 through the pipe A1 enters the cylinder A22 from the gaps between the blade plates A32 under the drive of the blade plate B39 on the rotating shaft C38 and the centrifugal force, and is discharged through the opened dust discharge groove 31 on the ring plate B30 under its own weight. Thus, the dusty air entering from the pipe A1 is effectively purified. The air purified by the purification mechanism 20 reaches the pipe C44 and is then further filtered and purified by the filtering device 42 for the second time before reaching the vehicle interior, thereby completing the purification of the air inside the vehicle.

[0052] Since the dust discharge groove 31 on the middle ring plate B30 of the purification mechanism 20 discharges a small amount of air while discharging sand or dust, the air flow rates in the pipes A1 and B41 are reduced. When the flow meter 3 detects a reduction in the flow rate in the pipe A1, it generates an electrical signal and transmits the electrical signal to the control system. The control system controls the motors A13 and B46 corresponding to the air supplement mechanism 21 to start running. The motor B46 drives the baffle 45 to open the pipe C44. At the same time, the motor A13 corresponding to the air supplement mechanism 21A drives the rotating shaft C38 and the ring plate C33 in the air supplement mechanism 21 to rotate through a series of transmissions, and the two rotate in opposite directions and at opposite rotational speeds. The ring plate C33 in the air supplement mechanism 21 drives all the corresponding vane plates A32 and the ring plate B30 to rotate synchronously. The dust discharge groove 31 on the ring plate B30 is quickly and reciprocally opened and closed by the stopper 25 on the inner wall of the corresponding cylinder A22. The outside air enters the space between all the vane plates A32 in the air supplement mechanism 21 through the gap between the filter screen 51 at the lower end of the horn 50 and the heating pipe 49 under the negative pressure in the pipe B41, and then vertically enters the pipe B41 through the pipe C44 and reaches the vehicle interior. The rotating shaft C38 in the air supplement mechanism 21 drives the vertically flowing air to rotate quickly through the vane plates A32 on it, and basically does not leak from the gaps between the vane plates A32. A small amount of air collides with the vane plates A32 during the rotation process, is reflected and returned under the obstruction of all the corresponding vane plates A32, and moves upward with most of the air. Another small amount of air enters the cylinder A22 through the gaps between the vane plates A32 and is discharged when the dust discharge groove 31 on the ring plate B30 is opened.

[0053] Meanwhile, the sand or dust in the air entering between all the vane plates A32 in the air supplement mechanism 21 through the horn 50, the cylinder B27, and the ring sleeve E29 is driven by the vane plates B39 on the corresponding rotating shaft C38 and under the centrifugal force, enters the cylinder A22 from the gaps between the vane plates A32 at a relatively high radial speed, and is discharged through the opened dust discharge groove 31 on the ring plate B30 under its own weight. As a result, the air supplemented from the outside is effectively purified. The outside air purified by the air supplement mechanism 21 reaches the pipe C44 and then passes through the secondary filtration and purification of the filtration device 42 again to reach the vehicle interior, thus completing the air supplement to the vehicle interior.

[0054] When the outside air enters through the filter screen 51 at the lower end of the horn 50, large pieces of garbage or sand in the air are blocked and screened out. The sand particles entering the air supplement mechanism 21 along with the air are relatively small in size, preventing large particle sand from entering and blocking the air supplement mechanism 21. When the air passes through the heating pipe 49, since the cross-section of the heating pipe 49 is a quadrilateral with a smaller included angle at the lower end and a larger included angle at the upper end, this structure of the heating pipe 49 not only increases its heat dissipation area but also increases the heating travel of the air to a certain extent, ensuring that the entering outside air can be quickly heated during the process of passing through the heating pipe 49, thereby preventing the entering outside air from condensing in the air supplement mechanism 21 and avoiding sand or dust in the entering air from adhering to the inner wall of the air supplement mechanism 21 and being difficult to clean, which may block the dust discharge groove 31 in the air supplement mechanism 21.

[0055] When the purification of the air inside the vehicle is completed, the control system controls the two motors A13 to drive the ring plate B30 in the air supplement mechanism 21 and the purification mechanism 20 to rotate until the dust discharge groove 31 on it is closed by the corresponding stopper 25 and then stops running. The motor B46 drives the baffle 45 to close the pipe C44.

[0056] After long-term use, a lot of dust will adhere to the air supplement mechanism 21 and the purification mechanism 20. At this time, only need to unscrew the air supplement mechanism 21 and the purification mechanism 20 from the ring sleeve C19 of the vehicle body 5 for flushing. After the air supplement mechanism 21 and the purification mechanism 20 are unscrewed, the two ring sleeves B17 slide down a certain extent under the action of the corresponding return springs 16, and the hexagonal sleeves 40 on the two rotating shafts B10 are disengaged from the corresponding rotating shafts C38.

[0057] After the air supplement mechanism 21 and the purification mechanism 20 are rinsed with water, just screw the air supplement mechanism 21 and the purification mechanism 20 tightly onto the corresponding ring sleeve C19 again. During the process of screwing the air supplement mechanism 21 and the purification mechanism 20 tightly onto the corresponding ring sleeve C19, the teeth 18 on the two ring sleeves B17 first engage with the teeth 18 on the corresponding ring sleeve F34 and compress the return spring 16. Then, the hexagonal heads on the two rotating shafts B10 are inserted into the hexagonal sleeves 40 on the corresponding rotating shafts C38 to complete the transmission connection between the air supplement mechanism 21 and the purification mechanism 20 and the corresponding motor A13.

[0058] In summary, the beneficial effects of the present invention are as follows: During the process of the purification mechanism 20 in the present invention purifying the air inside the vehicle or the air supplement mechanism 21 purifying the air supplemented from outside the vehicle into the vehicle, it will continuously discharge the filtered sand or dust, thereby prolonging the filtering time of the air inside the vehicle or the air supplemented into the vehicle by the present invention, extending its own cleaning cycle, and reducing the maintenance cost.

[0059] The present invention can be used for the internal circulation of clean air inside the vehicle and can also be used for effectively purifying the dusty air inside the vehicle, with a wide range of applications.

[0060] After being used for a long time, the purification mechanism 20 and the air supplement mechanism 21 in the present invention only need to be disassembled and cleaned by flushing with water. After cleaning, they are reinstalled on the vehicle for reuse, reducing the maintenance cost of the vehicle due to the need to replace the air filter element.
