[0001] This utility model relates to the technical field of air purification devices, and in particular to an air filtration and purification device with a cleaning function. Background Technology

[0002] As people's quality of life improves, they are paying more and more attention to their health. To reduce the probability of disease, air purification and filtration devices are generally used to purify the surrounding air. Air filtration and purification devices are devices used to remove pollutants from the air. They can effectively remove dust, pollen, smoke, etc., to ensure that we breathe healthy and safe air. They are widely used in dusty places such as workshops.

[0003] Existing air filtration and purification devices typically contain filters that actively or passively allow air to pass through them. The filters trap dust, particles, and other harmful substances in the air, thus purifying it. However, these filters can become clogged over time, requiring periodic removal for cleaning or replacement. After cleaning, the filters need to be dried before reuse, which is time-consuming. Furthermore, the air filtration and purification device cannot be activated during the cleaning and drying process, resulting in unsustainable operation. To address this technical problem, this invention proposes an air filtration and purification device with a cleaning function. Utility Model Content

[0004] The main objective of this invention is to provide an air filtration and purification device with a cleaning function, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An air filtration and purification device with a cleaning function includes a housing. Two fixed plates are fixedly connected to the inner wall of the housing. Each fixed plate has three cavities inside, and the cavities on the two fixed plates correspond one-to-one. A rotating plate is slidably connected between the two fixed plates. Three filters corresponding to the positions of the cavities are installed on the inner wall of the rotating plate. A power mechanism is provided on the lower surface of the rotating plate. A wind mechanism is provided inside the first cavity. A cleaning mechanism is provided inside the second cavity. An air outlet is provided on one side of the third cavity.

The outer surface of the connecting pipe is connected to the fixed plate located below the rotating plate.

[0007] Preferably, the power mechanism includes a first electric motor, the output end of which is fixedly connected to a connecting rod, the outer surface of which passes through the fixed plate at the lower part of the rotating plate and is fixedly connected to the center of the rotating plate.

[0008] Preferably, a sealing cover is installed on the fixing plate at the cavity position. There are five sealing covers, two of which are installed on the upper fixing plate and the remaining three are installed on the lower fixing plate.

[0009] Preferably, the wind power mechanism includes an air inlet plate, the outer surface of which is fixedly connected to a fixed plate, and a fan is provided below the air inlet plate, which is installed inside the cavity.

[0010] Preferably, the cleaning mechanism includes a second motor, which is mounted on the upper surface of the sealing cover. The output shaft of the second motor passes through the sealing cover and extends downward. A brush plate is fixedly connected to the end of the output shaft of the second motor, and the lower surface of the brush plate is slidably connected to the filter screen.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, by setting up a power mechanism and a cleaning mechanism, when the filter screen is covered with a lot of dust, the power mechanism drives the rotating plate to rotate 120 degrees, causing the dust-covered filter screen to move into the cavity where the cleaning mechanism is located. The dust on the filter screen is removed by the cleaning mechanism, and then the cleaned filter screen moves into the cavity where the air outlet is located. The purified air flows downward through the connecting pipe into the cavity where the air outlet is located, passes through the cleaned filter screen and flows out from the air outlet. The flowing air passes through the cleaned filter screen, causing it to dry quickly. This process is repeated to continuously purify the air and achieve the effect of continuous use.

[0015] In this utility model, by setting up a cleaning mechanism and other components, a second motor drives the brush plate to rotate. The lower part of the brush plate is provided with bristles, which can brush and wash the filter screen. A water pump circulates water up and down and sprays it onto the filter screen to clean it. At the same time, the water can be reused repeatedly. The upper sealing cover of the cavity is provided with a water inlet and the lower part is provided with a water outlet, which extends from the side to the outside of the outer shell for easy water replacement.

Three filter screens 5 corresponding to the positions of the cavities 3 are installed on the inner wall of the rotating plate 4. A power mechanism 6 is provided on the lower surface of the rotating plate 4. The power mechanism 6 includes a first motor 601. A connecting rod 602 is fixedly connected to the output end of the first motor 601. The outer surface of the connecting rod 602 passes through the fixed plate 2 at the lower part of the rotating plate 4 and is fixedly connected to the center of the rotating plate 4. The first motor 601 can drive the rotating plate 4 to rotate.

[0024] The first cavity 3 is equipped with a wind mechanism 7, which includes an air inlet plate 701. The outer surface of the air inlet plate 701 is fixedly connected to the fixed plate 2. A fan 702 is installed below the air inlet plate 701. The fan 702 is installed inside the cavity 3. The air inlet plate 701 is used to protect the fan 702 below to prevent large objects from falling in. The fan 702 can drive the air above the air inlet plate 701 to move downward, so that it passes through the filter screen 5 below.

[0025] The second cavity 3 houses a cleaning mechanism 8, which includes a second motor 801 mounted on the upper surface of the sealing cover 11. The output shaft of the second motor 801 passes through the sealing cover 11 and extends downwards. A brush plate 802 is fixedly connected to the end of the output shaft of the second motor 801. The lower surface of the brush plate 802 is slidably connected to the filter screen 5. The second motor 801 can drive the brush plate 802 to rotate. The lower part of the brush plate 802 is provided with bristles for brushing the filter screen 5. A water pump 803 is located below the fixed plate 2. The input of the water pump 803... The end is connected to the bottom of the cavity 3. The output end of the water pump 803 is connected to the water supply pipe 804. The outer surface of the water supply pipe 804 passes through the outer shell 1 and the fixing plate 2 and extends to the upper part of the filter screen 5. The end of the water supply pipe 804 is connected to the water spray plate 805. The cavity 3 located at the cleaning mechanism 8 is filled with cleaning water. The water pump 803 makes the water circulate up and down and spray it onto the filter screen 5 to clean the filter screen 5. At the same time, the water can be reused repeatedly. The sealing cover 11 at the top of the cavity 3 is provided with a water inlet and the bottom is provided with a water outlet, which extends from the side to the outside of the outer shell 1 for easy water replacement.

[0026] The bottom of the outer casing 1 is provided with a support plate 12. The upper surface of the support plate 12 is fixedly connected to the first motor 601 and the water pump 803, and the first motor 601 and the water pump 803 are supported and fixed by the support plate 12.

[0027] An air outlet 9 is provided on one side of the third cavity 3. The outer surface of the air outlet 9 penetrates the outer shell 1 and extends to the outside. A connecting pipe 10 for ventilation is installed between the first cavity 3 and the third cavity 3. The outer surface of the connecting pipe 10 is connected to the fixed plate 2 located at the lower part of the rotating plate 4. A sealing cover 11 is installed on the fixed plate 2 at the position of the cavity 3. There are five sealing covers 11. Two sealing covers 11 are installed on the upper fixed plate 2, and the other three sealing covers 11 are installed on the lower fixed plate 2. The sealing covers 11 are used to seal the cavities 3 on the fixed plate 2, except for the cavity 3 where the wind mechanism 7 is located.

[0028] It should be noted that in actual use, the device uses the wind mechanism 7 to draw polluted external air into the first cavity 3, and the filter 5 filters the air, intercepting the dust, thereby purifying the air and achieving the effect of air purification.

[0029] When filter screen 5 accumulates a significant amount of dust, the power mechanism 6 drives the rotating plate 4 to rotate 120 degrees, moving the dust-covered filter screen 5 into the cavity 3 containing the cleaning mechanism 8. The cleaning mechanism 8 removes the dust from the filter screen 5 through water extraction and brushing. The power mechanism 6 then moves the cleaned filter screen 5 into the cavity 3 containing the air outlet 9. Meanwhile, the fan mechanism 7 draws purified air downwards through the connecting pipe 10 into the cavity 3 containing the air outlet 9, then upwards, passing through the cleaned filter screen 5 and flowing out from the air outlet 9. The flowing air quickly dries the cleaned filter screen 5, allowing it to be rotated back to the fan mechanism 7 for reuse. This process continues, with three filters 5 operating simultaneously – one filtering, one cleaning, and one drying. Every so often, the rotating plate 4 rotates 120 degrees, ensuring continuous operation even while the filters 5 are being cleaned, achieving a sustained air purification effect.
