The controller 17 controls the output shaft of the telescopic motor 19 to move leftward to drive the driving rod 161 to move leftward, the left end of the slide rail 162 of the driving rod 161 does not generate a pushing force on the slider 163 any longer, the plugging head 151 plugs the first air port 6 under the suction force of the vacuum pipeline 4 and the acting force of the elastic hinge portion 152, and the vacuum pump 5 stops working. Meanwhile, the LED panel 9 drives the supporting rod 11 to move leftwards, the first filter screen 12 on the supporting rod 11 moves leftwards, the rubber sheet 13 on the first filter screen 12 is moved away from the air inlet 2, the filter chamber 101 is in a low-pressure state, outside air enters the filter chamber 101 through the air inlet 2, and the LED panel 9 irradiates the porous carrier 8 to purify the air.

The above process is repeated to realize the purification of air and the continuous air supply of the fuel cell. Thus, an intermittent cleaning of the air is achieved by the filtering chamber 101 and a continuous air supply is achieved by the buffer chamber 103.

In the above-mentioned use process, when the rubber sheet 13 blocks the air inlet 2, the transmission shaft 21 and the rotation shaft 2001 establish a transmission connection relationship, and the use of the cleaning mechanism 20 is realized. When it is not necessary to filter the air entering the filtering chamber 101, a first filter 12 may be arranged between the porous carrier 8 and the air inlet 2, the air may flow partially around the first filter 12 to the porous carrier 8; when it is desired to filter air entering the filtering chamber 101, the first filter 12 may be arranged in a recess, and air must pass the first filter 12 before it can flow through the porous carrier 8, which is achieved by a movement of the rod 11 in a left-right direction.

By dividing the box body 1 into the filter chamber 101, the equipment chamber 102 and the buffer chamber 103, air can enter the buffer chamber 103 after entering the filter chamber 101 and being fully filtered, thereby ensuring the purity of air purification, and the vacuum pump 5 is arranged between the filter chamber 101 and the buffer chamber 103, thereby being capable of pumping the filtered air in the filter chamber 101 into the buffer chamber 103, and ensuring that the air in the buffer chamber 103 is in a high-pressure state and is uniformly and continuously exhausted outwards by matching with the control valve 23.

The blocking mechanism 15 and the rubber sheet 13 on the first filter screen 12 are linked through the linkage mechanism 16, when the linkage mechanism 16 drives the LED panel 9 to move rightwards, the rubber sheet 13 blocks the air inlet 2, the blocking mechanism 15 opens the first air inlet 6, and purified air in the filter chamber 101 is pumped into the buffer chamber 103 through the vacuum pump 5; when the linkage mechanism 16 drives the LED panel 9 to move leftward, the rubber sheet 13 opens the air inlet 2, the blocking mechanism 15 blocks the first air inlet 6, and the low-pressure state of the filtering chamber 101 introduces the outside air from the air inlet 2 into the filtering chamber 101 for purification, so that the interval action process of air intake and exhaust of the filtering chamber 101 is realized, the air purification effect is ensured, and unpurified and clean air is prevented from entering the buffer chamber 103.

Meanwhile, the groove is formed in the porous carrier 8, so that the first filter screen 12 can be arranged in the groove, air is filtered and decontaminated through the first filter screen 12, high cleanliness of air entering the photocatalytic region is guaranteed, and whether the first filter screen 12 is placed in the groove or not can be determined according to needs; meanwhile, the transmission shaft 21 and the cleaning mechanism 20 are arranged, the cleanness of the rear end face of the porous carrier 8 is ensured through the cleaning mechanism 20, and the efficiency of photocatalysis is prevented from being influenced by pollution.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
