[0057] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0058] Example 1

[0059] A self-cleaning caravan air purifier, such as Figure 1-Figure 2 As shown, it includes an outer shell 1, a filter 2, a fan 3, a cleaning mechanism 4 and an opening mechanism 5. The filter 2 is fixedly connected to the inside of the outer shell 1, the fan 3 is fixedly connected to the lower side of the rear of the outer shell 1, the cleaning mechanism 4 is provided on the outer shell 1, and the opening mechanism 5 is provided at the inner lower part of the outer shell 1.

[0060] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the cleaning mechanism 4 includes a motor 41, a first screw rod 42, a spray head 43, a first guide rod 44 and a conduit 45. The motor 41 is fixedly connected to the left side of the upper part of the shell 1, and the first screw rod 42 is fixedly connected to the output shaft of the motor 41. The first screw rod 42 passes into the interior of the shell 1, and the spray head 43 is threadedly connected to the first screw rod 42. The rear part of the spray head 43 is in contact with the filter 2. The first guide rod 44 is fixedly connected to the right front side of the interior of the shell 1. The spray head 43 is slidably connected to the first guide rod 44. A conduit 45 is connected to the middle position of the upper part of the spray head 43. The conduit 45 is connected to the spray head 43, the conduit 45 is fixedly connected to the shell 1, and the conduit 45 passes through the upper part of the shell 1.

[0061] like Figure 2 、 Figure 5 and Figure 6As shown, the opening mechanism 5 includes a sliding baffle 51 and a cylinder 52. A rectangular groove is opened on the rear lower side of the interior of the shell 1. The cylinder 52 is fixedly connected to the rear lower side of the interior of the shell 1. The cylinder 52 passes through the rear of the shell 1. The sliding baffle 51 is fixedly connected to the telescopic rod of the cylinder 52. The sliding baffle 51 is located above the rectangular groove and is slidably connected to the inner lower part of the shell 1.

[0062] When people need to clean the air purifier, first, water is transported into the spray head 43 through the conduit 45, and then the water is sprayed onto the filter 2 through the spray head 43 to rinse the filter 2. At this time, the motor 41 can also be started, and the output shaft of the motor 41 will start to rotate, driving the first screw rod 42 to start rotating. Due to the limiting effect of the first guide rod 44, the spray head 43 will start to move downward along the first screw rod 42, and rinse the filter 2 from top to bottom, cleaning the impurities on the filter 2 to ensure the cleanliness of the filter 2, thereby improving the working efficiency of the air purifier. At the same time, people can also set the time through the motor 41 to let the spray head 43 clean the filter 2 regularly. This not only prevents people from forgetting to clean the filter 2, but also reduces people's workload. The air purifier will automatically clean at regular intervals, which can improve the air purification effect of the air purifier. At the same time, people can control the telescopic rod of the cylinder 52 to retract backwards. At the same time, by controlling the telescopic rod of the cylinder 52 to retract backward, the sliding baffle 51 is driven to move backward, so that the sewage can flow out of the air purifier.

[0063] Example 2

[0064] On the basis of Example 1, Figure 1 、 Figure 2 and Figure 7As shown, a blocking mechanism 6 is also included, which includes a second screw rod 61, a blocking plate 62, a second guide rod 63 and a transmission belt 64. The second screw rod 61 is rotatably connected to the left rear side of the interior of the shell 1, and a transmission belt 64 is wound between the second screw rod 61 and the first screw rod 42 through a transmission wheel. The blocking plate 62 is threadedly connected to the second screw rod 61, and the front part of the blocking plate 62 is semicircular. The blocking plate 62 is located on the rear side of the filter screen 2, and the second guide rod 63 is fixedly connected to the right rear side of the interior of the shell 1. The blocking plate 62 is slidably connected to the second guide rod 63.

[0065] When the first screw rod 42 starts to rotate, it will drive the transmission belt 64 to start rotating, thereby causing the second screw rod 61 to start rotating. Due to the limiting effect of the second guide rod 63, the blocking plate 62 will be driven to start moving downward. Since the first screw rod 42 and the second screw rod 61 start to rotate almost at the same time, the time and speed at which the blocking plate 62 and the spray head 43 start to move downward are almost the same, that is, the blocking plate 62 can always be blocked behind the spray head 43, which can buffer the impact force of the water flow and prevent the water flow from splashing everywhere. At the same time, since the front part of the blocking plate 62 is a semicircular arc shape, the water flow can be sprayed along the blocking plate 62 to the back side of the filter 2 to clean the back side of the filter 2, which not only improves the utilization rate of the water flow, but also further improves the cleaning effect of the filter 2, thereby improving the working efficiency of the air purifier. When the filter 2 is cleaned, the output shaft of the motor 41 drives the first screw rod 42 to rotate in the opposite direction, driving the transmission belt 64 to rotate in the opposite direction, so that the blocking plate 62 moves upward and resets.

[0066] like Figure 2 、 Figure 8 and Figure 9 As shown, it also includes an ejection mechanism 7, which includes a slide bar 71, a rack 72, a compression spring 73, a gear 74, a charging box 75 and a third screw rod 76. A square slot is opened on the left rear side of the shell 1, and the right rear side of the filter screen 2 is slidably connected to the slide bar 71. The blocking plate 62 is squeezed and matched with the slide bar 71. The rear side of the slide bar 71 is fixedly connected to the rack 72. The rear lower side of the shell 1 can be slidably connected to the charging box 75. The charging box 75 can pass through the shell 1 through the square slot. The charging box 7 5 is located below the rectangular slot, and a compression spring 73 is wound between the rear side of the slide bar 71 and the right rear side of the interior of the housing 1. The upper portion of the compression spring 73 is connected to the slide bar 71, and the lower portion of the compression spring 73 is connected to the right rear side of the interior of the housing 1. A third screw rod 76 is threadedly connected to the right rear side of the charging box 75. The third screw rod 76 is rotatably connected to the housing 1 and passes through the right side of the charging box 75. A gear 74 is connected to the right side of the third screw rod 76, and the gear 74 and the rack 72 are meshed with each other.

[0067] The telescopic rod of the cylinder 52 drives the sliding baffle 51 to move backward, and the sewage will flow into the charging box 75 and be collected by the charging box 75. When the blocking plate 62 moves downward and contacts the slide bar 71, it will squeeze the slide bar 71 downward, causing the slide bar 71 to move downward, and the compression spring 73 is compressed, driving the rack 72 to move downward as well. The rack 72 will begin to mesh with the gear 74, causing the gear 74 to start rotating, driving the third screw rod 76 to start rotating, and the charging box 75 will begin to move to the left, and pass through the square slot on the left rear side of the shell 1 to pass through the interior of the shell 1, and the charging box 75 will be pushed out of the shell 1 inside, it is convenient for people to see that sewage has been collected in the charging box 75, reminding people to deal with the sewage in the charging box 75 so as to collect sewage during the next cleaning. When the cleaning work is completed, the blocking plate 62 moves upward and resets, and will gradually move away from the slide bar 71, releasing the squeeze on the slide bar 71. The slide bar 71 will move upward and reset under the action of the compression spring 73, driving the rack 72 to move upward and reset as well. The rack 72 and the gear 74 will mesh in the reverse direction, driving the gear 74 to rotate in the reverse direction, thereby driving the third screw rod 76 to start rotating in the reverse direction, and driving the charging box 75 to move rightward and reset.

[0068] like Figure 2 、 Figure 10 and Figure 11 As shown, a scraping plate 81 is also included. The scraping plate 81 is threadedly connected to the second spiral rod 61. The scraping plate 81 is slidably connected to the second guide rod 63. The scraping plate 81 is located above the blocking plate 62, and the front of the scraping plate 81 is in contact with the filter screen 2.

[0069] When the second spiral rod 61 starts to rotate, it will also drive the scraper plate 81 to move downward. Since the scraper plate 81 is in contact with the rear part of the filter 2, the scraper plate 81 can scrape off the impurities remaining on the rear part of the filter 2, further improving the cleaning effect of the filter 2, thereby improving the working efficiency of the air purifier. When the second spiral rod 61 rotates in the opposite direction, it will drive the scraper plate 81 to move upward and reset.

[0070] like Figure 1 、 Figure 2 、 Figure 12 and Figure 13 As shown, a prompt mechanism 9 is also included, which includes a prompt sound 91, a first sensor 92 and a second sensor 93. The prompt sound 91 is fixedly connected to the left rear side of the shell 1, the first sensor 92 is fixedly connected to the right rear side of the loading box 75, and the second sensor 93 is fixedly connected to the left rear side of the inside of the shell 1. The second sensor 93 is squeezed and fitted with the first sensor 92, and the second sensor 93 is electrically connected to the prompt sound 91.

[0071] Since people do not always pay attention to the air purifier, it is possible that people do not notice that the charging box 75 has been pushed out. Therefore, when the charging box 75 starts to pass through the interior of the shell 1 to the left, it will also drive the first sensor 92 to move to the left. When the first sensor 92 contacts the second sensor 93, it will squeeze the second sensor 93, causing the prompt sound 91 to sound, thereby reminding people that the charging box 75 is full and needs to be processed in time. After cleaning the filter 2 and processing the charging box 75, the charging box 75 moves to the right and resets, so that the first sensor 92 is away from the second sensor 93, and the prompt sound 91 will no longer sound.

[0072] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
