[0002] As living standards improve, people are paying more attention to health and have higher requirements for indoor air cleanliness. Although ordinary household air purifiers have high purification levels, they are bulky and fixed in location. In open rooms, indoor air circulation takes a long time, and purified air is easily mixed with unpurified air again. For people who are active indoors, the air they breathe is only partially improved, and the air quality is not thoroughly purified. Therefore, the positive effect of existing purifiers is limited.

[0003] Patent publication number CN213348151U relates to a portable air purifier. This patent discloses a portable air purifier, which belongs to the field of air purification technology. It includes a shell and a handle frame. The shell is formed with an air inlet and an air outlet. The shell contains a purification chamber, an air intake chamber, and an air delivery chamber. A blower, an air intake pipe, and a first air delivery pipe are installed in the air intake chamber. A second air delivery pipe is installed in the air delivery chamber. A dust filter and an activated carbon filter are connected to the purification chamber. A connecting block and a controller are connected to the outer side of the shell. The connecting block is hinged to the handle frame. A caster wheel is connected to the bottom of the shell. Users can move the air purifier conveniently through the handle frame and the caster wheel. At the same time, the handle frame can be used to lift the air purifier, and the hinged design can effectively reduce the space occupied.

[0004] The aforementioned patent effectively solves the problem of air purifiers being inconvenient to move and carry. However, transporting them with casters and handles is still too cumbersome and takes up too much space. A smaller, more compact purifier should be adopted. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-13One embodiment of the present invention is: a portable mobile indoor air purifier, including a base 1, a U-shaped frame 101 fixedly installed on the base 1, a rotating shaft 102 rotatably passing through the side of the U-shaped frame 101, a cylinder 103 fixedly installed on the side of the rotating shaft 102, a fixing plate 104 fixedly installed on the inner wall of the cylinder 103, a motor 105 fixedly passing through the middle of the fixing plate 104, a fan 106 fixedly installed at the output end of the motor 105, and also including a flipping device, a cleaning device and a collecting device; The flipping device includes a second rotating shaft 2, which is rotatably mounted on the side of the U-shaped frame 101. A U-shaped rod 201 is fixedly mounted on the circumference of the second rotating shaft 2. A short nail 202 slides through the side of the U-shaped rod 201. A spring 203 is provided between the short nail 202 and the U-shaped rod 201. A gear 204 is fixedly mounted on the circumference of the second rotating shaft 2. A semi-circular disk 205 is fixedly mounted on the side of the U-shaped frame 101. A gear 206 is fixedly mounted on the circumference of the second rotating shaft 102. Under normal conditions, the entire cylinder 103 remains vertical due to the weight of the motor 105. When transporting, simply lift the U-shaped rod 201 to move the entire purifier. When in use, rotate the U-shaped rod 201 counterclockwise until it touches the base 1. When not in operation, it remains vertical. Lifting the U-shaped rod 201 during transport facilitates transportation. When in use, rotate the U-shaped rod 201 or directly pull the short nail 202 to rotate it.

[0020] Gear 1 204 meshes with gear 2 206. The semi-circular disk 205 has multiple through holes, which are on the same trajectory as the short nail 202. The rotating shaft 2 drives gear 1 204 to rotate counterclockwise, gear 1 204 drives gear 2 206 to rotate clockwise, gear 2 206 drives rotating shaft 1 102 to rotate clockwise, and rotating shaft 2 102 drives cylinder 103 to rotate clockwise around rotating shaft 1 102. After gear 1 204 and gear 2 206 mesh and transmit power, cylinder 103 rotates clockwise around rotating shaft 1 102 and drives the internal objects, which can adjust the direction.

[0021] In this embodiment, during operation: Under normal circumstances, the weight of the motor 105 keeps the entire cylinder 103 vertical. During transport, simply lifting the U-shaped rod 201 is sufficient to move the entire purifier. When needed, the U-shaped rod 201 is rotated counterclockwise until it touches the base 1. Simultaneously, the short pin 202 is pulled, causing the spring 203 to deform under tension. Alternatively, the short pin 202 can be pulled directly to rotate the U-shaped rod 201. The U-shaped rod 201 rotates around the rotating shaft 22 as its center. When rotated counterclockwise, the rotating shaft 2 drives the gear 1 204 to rotate counterclockwise, the gear 1 204 drives the gear 2 206 to rotate clockwise, the gear 2 206 drives the rotating shaft 1 102 to rotate clockwise, and the rotating shaft 2 102 drives the cylinder 103 to rotate clockwise around the rotating shaft 1 102. The cylinder 103 drives all the objects inside it to rotate together. After the direction is selected, the short nail 202 is released. Under the action of the spring 1 203, the short nail 202 is inserted into the through hole of the semi-circular disk 205 to form a positioning and prevent it from flipping during operation.

[0022] Please see Figures 1-13 Based on the above embodiments, in another embodiment of the present invention, the cleaning device includes a fixing member 3, which is fixedly installed on the circumferential surface of the cylinder 103. An L-shaped part 301 is rotatably installed on the circumferential surface of the fixing member 3. A semi-cylinder 302 is fixedly installed on the side of the L-shaped part 301. An L-shaped part 303 is fixedly installed on the circumferential surface of the semi-cylinder 302. A triangular block 304 is fixedly installed on the circumferential surface of the cylinder 103. A semi-circular part 305 is slidably installed on the inner wall of the cylinder 103. A semi-circular part 306 is slidably installed on the inner wall of the semi-cylinder 302. A long rod 307 is fixedly installed on the inner wall of the semi-circular part 305. A square block 308 is fixedly installed on the inner wall of the cylinder 103. A spring 309 is provided between the semi-circular part 305 and the square block 308. A cylinder 310 is fixedly installed on the side of the fan 106. A filter 311 is installed on the inner wall of the first semicircular part 305. After continuous operation, the surface of the filter 311 is covered with dust. At this time, the air permeability of the filter 311 decreases significantly and it becomes clogged. The motor 105 works normally. After receiving the suction force of the fan 106, the filter 311 moves to the left. When the filter 311 is clogged, it moves to the left under the suction force of the fan 106, which will drive the first semicircular part 305 and the second semicircular part 306 to move.

[0023] L-shaped part 303 has a groove 1, which engages with triangular block 304. The first semicircular part 305 is provided with a toothed block, the second semicircular part 306 is provided with a toothed groove, and the first semicircular part 305 and the second semicircular part 306 are provided with a sliding groove. The toothed block and the toothed groove mesh. The side of the cylinder 310 is provided with a rough surface. The first semicircular part 305 gradually returns to its original position. When it is necessary to replace the filter sheet 311, the second L-shaped part 303 can be pulled to open the semicircular cylinder 302. The semicircular cylinder 302 rotates around the fixed part 3 as the center. The semicircular cylinder 302 drives the second semicircular part 306 to rotate, and the filter sheet 311 gradually restores its air permeability. When replacing the filter sheet 311, the second L-shaped part 303 can be pulled to open the semicircular cylinder 302 to replace the filter sheet 311 in the sliding groove.

[0024] The cylindrical 103 has an inlet 4 for dust inlet and a groove 2. A filter screen 401 is installed in the groove 2. An L-shaped rod 402 is fixedly installed on the side of the semi-circular part 305. A round rod 403 slides through the L-shaped rod 402. A spring 3 404 is installed between the round rod 403 and the L-shaped rod 402. A ball 405 is fixedly installed on the round rod 403. A square box 406 is provided on the circumference of the cylindrical 103. After the dust falls from the filter screen 311, it needs to be... Timely collection: As the semicircular part 305 moves to the left, the ash inlet 4 gradually opens. At this time, the ash inlet 4 forms a passage with the square box 406 and the groove 2. The fan 106 rotates to generate suction, and the dust falling from the filter 311 will be sucked into the square box 406. The filter screen 401 keeps the air ventilated and blocks the dust from passing through. After the dust falls from the filter 311, the semicircular part 305 moves to the left to open the ash inlet 4, forming a passage with the square box 406 and the groove 2.

[0025] The square box 406 is connected to the ash inlet 4 and the groove 2, and the square box 406 is detachable. In order to prevent the filter screen 401 from being blocked, when the semi-circular part 305 moves to the left, it will drive the L-shaped rod 402 to move to the left. The L-shaped rod 402 drives the round rod 403 to move to the left, and the round rod 403 drives the ball 405 to move to the left. The fan 106 sucks the dust into the square box 406, and the filter screen 401 is ventilated and blocked. At the same time, the round rod 403 taps the filter screen 401 to prevent it from being blocked.

[0026] The semi-circular part 305 is set on the ash inlet 4. The ball 405 is on the movement trajectory of the fan 106. As the ball 405 moves to the left, the fan 106 will contact the surface of the ball 405. After receiving the thrust of the fan 106, the ball 405 moves downward, the spring 3 404 deforms, and the bottom of the round rod 403 strikes the filter screen 401. Under the action of the spring 3 404, it reciprocates. The cleaning continues until the filter screen 311 gradually regains its air permeability.

[0027] In this embodiment, during operation: After continuous operation, the surface of the filter 311 becomes covered with dust, significantly reducing its air permeability and causing blockage. The motor 105 operates normally, and the filter 311 moves to the left under the suction of the fan 106. The filter 311 drives the first semicircular component 305 and the second semicircular component 306 to move to the left. During this movement, the second spring 309 deforms under the thrust of the first semicircular component 305. The filter 311 then gets closer and closer to the cylinder 310. When the filter 311 contacts the cylinder 310, the cylinder 310 rotates under the drive of the motor 105 output, and the rough surface of the cylinder 310 rubs against the side of the filter 311. The filter element 311 rotates under the drive of the cylinder 310. After the filter element 311 rotates, the long rod 307 will scrape off the dust on the side to clean the dust. After the dust on the filter element 311 is reduced, the permeability increases, and the semi-circular part 305 gradually returns to its original position. When the filter element 311 needs to be replaced, the semi-circular cylinder 302 can be opened by pressing the L-shaped part 303. The semi-circular cylinder 302 rotates around the center of the fixing part 3, and the semi-circular part 302 drives the semi-circular part 306 to rotate. Only the filter element 311 in the sliding groove of the semi-circular part 305 needs to be replaced. When the semi-circular cylinder 302 is closed, the tooth groove of the semi-circular part 306 engages with the semi-circular part 305, and the filter element 311 is exactly in the sliding groove.

[0028] In this embodiment, as dust falls from the filter 311, it needs to be collected promptly. During the leftward movement of the semicircular component 305, the dust inlet 4 gradually opens, forming a passage with the square box 406 and the groove. The fan 106 rotates, generating suction, and the dust falling from the filter 311 is sucked into the square box 406. The filter screen 401 maintains ventilation and blocks dust from passing through. To prevent clogging of the filter screen 401, the leftward movement of the semicircular component 305 drives the L-shaped rod 402 to move to the left, which in turn drives the round rod. 403 moves to the left, and the round rod 403 drives the round ball 405 to move to the left. During the movement of the round ball 405 to the left, the fan 106 will contact the surface of the round ball 405. After receiving the thrust of the fan 106, the round ball 405 moves downward, the spring 3 404 deforms, and the bottom of the round rod 403 knocks on the filter screen 401 to prevent dust accumulation. After the round rod 403 moves upward under the thrust of the spring 3 404, it is pushed down again by the fan 106, forming a reciprocating motion. After the dust on the filter screen 311 is reduced, the permeability increases, and the semi-circular part 305 gradually returns to its original position.
