[0030] The utility model discloses a kind of self-cleaning and humidity control air duct filter devices, as follows: Figures 1 to 3 , Describes the utility model embodiment a kind of self-cleaning and humidity control air duct filter devices.

[0031] A kind of self-cleaning and humidity control air duct filter device, including shell 1 and filter cotton 2, the shell 1 is sequentially provided with left partition plate 11 and right partition plate 12 from left to right, the left partition plate 11 and the right partition plate 12 sequentially divide the shell 1 into left bin 13, ventilation cavity 14 and right bin 15 from left to right;

[0032] The shell 1 is provided with air outlet on the front side of the ventilation cavity 14, the shell 1 is provided with air inlet on the rear side of the ventilation cavity 14, the air inlet, the ventilation cavity 14 and the air outlet are communicated with each other, the air outlet is connected with the output end of air supply power structure, the air outlet is connected with the input end of air outlet power structure;

[0033] The left bin 13 and the right bin 15 are provided with winding assembly 3 and spraying assembly 4, the left end of the filter cotton 2 is wound in the movable end of the winding assembly 3 of the left bin 13, the right end of the filter cotton 2 sequentially passes left partition plate 11 and right partition plate 12, and is wound in the movable end of the winding assembly 3 of the right bin 15, two winding assemblies 3 are used for pulling and pulling back the filter cotton 2, the spraying assembly 4 is used for spraying for the filter cotton 2 located in the same side.

[0034] Operation process is as follows: start the spraying assembly 4 in left bin 13, ensure that the spraying assembly 4 sprays water flow on the filter cotton 2 located in left bin 13, so that filter cotton 2 absorbs moisture.The winding assembly 3 of both ends is started synchronously, and the winding assembly 3 is operated together, so that the filter cotton 2 located in left bin 13 moves from left to right, and then is wound on the winding assembly 3 located in right bin 15.Because the spraying assembly 4 sprays the filter cotton 2 at all times, the wet filter cotton 2 moves to ventilation cavity 14.Continue to start the winding assembly 3 of both ends, so that the wet filter cotton 2 passes through right partition plate 12, to ensure that the filter cotton 2 located in ventilation cavity 14 is wet.

[0035] When the wet filter cotton 2 passes through the right partition plate 12 and is located in the right bin 15, the spraying assembly 4 of the right bin 15 sprays water flow with impact force on the filter cotton 2 to wash away the dust and other impurities of the filter cotton 2, thereby cleaning the filter cotton 2.

[0036] When most of the filter cotton 2 is located in the right bin 15, the winding assemblies 3 at both ends are started to rotate in opposite directions, at this time, the filter cotton 2 located in the right bin 15 moves from right to left and is then wound on the winding assembly 3 located in the left bin 13.

[0037] Then the air supply power structure delivers external air to the air inlet, and the external air passes through the air inlet, the filter cotton 2 and the air outlet in turn and is discharged to the outside from the air outlet power structure. It should be pointed out that the air supply power structure and the air outlet power structure are both air pumps, which provide a stable and reliable power source for the flow of air, avoiding the situation that the filtering effect is reduced due to insufficient power of external air.

[0038] Among them, the left partition plate 11 and the right partition plate 12 are both provided with vertical through holes for the filter cotton 2 to pass through, which ensures that the filter cotton can pass through the ventilation cavity 12 to play a filtering effect on the air.

[0039] The device can effectively filter out dust, particulate matter and other impurities in the air through the filter cotton 2 arranged in the left bin 13 and the right bin 15, and improve the air quality. At the same time, the addition of the spraying assembly 4 enables the filter cotton 2 to also be subjected to humidification treatment during the filtering process, thereby releasing fresher and more humid air, which is particularly suitable for use in dry environments and helps to improve indoor humidity and enhance living comfort.

[0040] The spraying assembly 4 and the winding assembly 3 cooperate with each other to rotate the filter cotton 2 in time, which not only avoids the use of the same piece of filter cotton 2 for a long time, but also ensures that the filter cotton 2 located in the ventilation cavity 14 is kept in a wet state at all times. The wet filter cotton 2 can form a thin layer of water film, which can adsorb and retain more impurities in the air, thereby significantly improving the filtering efficiency and making the filtering effect more outstanding. Moreover, the wet filter cotton 2 can also have a humidifying effect. When dry air passes through the wet filter cotton 2, the moisture in the filter cotton 2 will gradually be released into the air, thereby increasing the humidity of the air and providing people with a more comfortable living environment, solving the problem of manual replacement of the filter cotton 2 by the user in traditional filtering devices.

[0041] The winding assembly 3 comprises a winding roller 31, a winding worm gear 32, a winding worm 33 and a driving member 34, the winding roller 31 is vertically rotatably installed on the shell 1, the top of the winding roller 31 is fixedly sleeved with the winding worm gear 32, the top wall of the shell 1 is provided with the driving member 34, the driving end of the driving member 34 is fixedly connected with the winding worm 33, and the winding worm gear 32 is in mesh with the winding worm 33.

[0042] The end of the filter cotton 2 is wound on the winding roller 31.

[0043] It is worth noting that the driving member 34 is preferably an electric motor. The winding worm 33 is driven to rotate by the driving member 34, and since the winding worm gear 32 is in mesh with the winding worm 33, the winding worm gear 32 drives the winding roller 31 to rotate accurately. The rotation speed and frequency of the driving member 34 are controlled to accurately control the winding roller 31, thereby ensuring effective cleaning and uniform use of the filter cotton 2.

[0044] In order to better protect the winding assembly 3 from the water flow, two horizontal partition plates are arranged on the inner side of the shell 1, one of which is horizontally connected with the inner wall of the shell 1 and the left partition plate 11, and the other is horizontally connected with the shell 1 and the right partition plate 12. The winding worm gear 32, the winding worm 33 and the driving member 34 are located above the partition plates, and the end of the winding roller 31 and the filter cotton 2 are located below the partition plates.

[0045] The spraying assembly 4 comprises a water inlet pipe 41 and a water distributor 42, the output end of the water inlet pipe 41 is communicated with the water distributor 42, and the spraying direction of the water distributor 42 horizontally faces the filter cotton 2.

[0046] The water inlet pipe 41 is communicated with a water supply device outside, and the water flow flows from the water inlet pipe 41 into the water distributor 42, and then the water distributor 42 disperses the water into fine water flow with impact force and sprays it horizontally on the filter cotton 2, so that the water can be uniformly distributed on the surface of the filter cotton 2, which can not only avoid the situation that the filter cotton 2 is locally too wet or too dry, but also can wash away the dust and other impurities of the filter cotton 2, thereby improving the humidifying and filtering effect.

[0047] The water sprayed on the filter cotton 2 helps to adsorb and fix the dust, particulate matter and other impurities in the air, enhances the filtering effect of the filter cotton 2, and thus improves the overall air purification capacity.

[0048] The water distributor 42 sprays outward, which not only can moisten the filter cotton 2 and effectively reduce the dryness of the air in the device and the room, thereby reducing the generation of static electricity, but also can wash away the dust and other impurities of the filter cotton 2, thereby playing a role of automatically cleaning the filter cotton 2.

[0049] The bottom wall of the left bin 13 and the right bin 15 is provided with a drainage slope 51, and the lowest point of the drainage slope 51 is flush with the input end of the first drainage pipe 52.

[0050] The bottom wall of the ventilation cavity 14 is provided with a water collecting disc 53, and the bottom of the water collecting disc 53 is connected with the second drainage pipe 54.

[0051] The drainage slope 51 and the first drainage pipe 52 arranged at the bottom of the left bin 13 and the right bin 15 can ensure that the excess moisture generated during the spraying humidification process or the water droplets on the filter cotton 2 can quickly flow along the drainage slope 51 to the lowest point. Since the lowest point of the drainage slope 51 is flush with the input end of the drainage pipe, it ensures that the moisture can smoothly flow into the first drainage pipe 52 without leakage or overflow. Therefore, the accumulated water in the drainage slope 51 can be smoothly discharged outside the device through the first drainage pipe 52, effectively avoiding the accumulation of moisture inside the left bin 13 and the right bin 15, reducing the problem of bacterial breeding and corrosion caused by accumulated water.

[0052] The water collecting disc 53 arranged at the bottom wall of the ventilation cavity 14 can not only collect the water droplets falling downward from the filter cotton 2, but also collect the dust particles adhering to the water droplets, because the humid filter cotton 2 has good filtering effect. Moreover, the water collecting disc 53 is connected with the second drainage pipe 54, so that the water collecting disc 53 can timely discharge the sewage containing dust to prevent the dust from re-entering the air, thereby further improving the cleanliness of the air.

[0053] The input end of the water inlet pipe 41 is provided with a flow regulating valve 43.

[0054] The flow regulating valve 43 can accurately control the water flow entering the water distributor 42, thereby adjusting the wet state of the filter cotton 2, avoiding unnecessary energy consumption caused by excessive wetting of the filter cotton 2, thereby saving water resources and energy.

[0055] The housing 1 is provided with a grille at the air inlet and the air outlet.

[0056] The grille of the air inlet can preliminarily filter the air entering the device, intercepting a part of larger particulate matter and impurities. When the air passes through the humid filter cotton 2, the filtering load of the filter cotton 2 will be relatively reduced, and the filtering efficiency will also be correspondingly improved. The grille can effectively prevent insects or other foreign matters from entering the inside of the device, thereby protecting the key components such as the filter cotton 2 from damage, prolonging the service life of the device, and reducing the failure and maintenance cost caused by the entry of foreign matters.

[0057] The left partition plate 11, the right partition plate 12 and the housing 1 are all provided with a thermal insulation layer.

[0058] The setting of the heat preservation layer effectively enhances the heat preservation performance of the device.

[0059] In the cold season, the heat preservation layer can reduce heat loss, the spray assembly 4 which sprays warm water outward can maintain the appropriate working temperature of the filter cotton 2, and the water flow on the filter cotton 2 is prevented from being frozen, so that the situation that the filter cotton 2 cannot filter air appears.

[0060] The technical principle of the utility model is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the utility model, and cannot be interpreted as limiting the protection scope of the utility model in any way. Based on the explanation herein, other specific embodiments of the utility model can be conceived by those skilled in the art without creative labor, and these embodiments will all fall within the protection scope of the utility model.
