Description

Technical Field

[0001] The present invention relates to the technical field of air purifiers, and in particular to an intelligent filter adjustment structure and an air purifier with a photovoltaic panel. Background Art

[0002] An outdoor air purification device is a device used to improve outdoor air quality. It mainly removes pollutants in the air, such as particulate matter, harmful gases (such as sulfur dioxide, nitrogen oxides, etc.) and microorganisms, through filtration, adsorption, chemical reaction and other technologies. These devices are usually used in urban environments and can effectively reduce the impact of air pollution on human health.

[0003] Existing outdoor air purification devices are usually equipped with a drying layer, a filter and an exhaust fan. When the air in the environment needs to be purified, the exhaust fan can be started to make the gas pass through the drying layer first to remove moisture in the air, thereby improving the device's filtering effect on particles in the air. At this time, the gas passes through the filter again, and the particles in the air are separated by the filter, thereby achieving the effect of purifying the air. In order to improve the filtering effect of the device, the filter is often composed of a plurality of filter materials of different materials and mesh sizes, such as a coarse-effect filter and a medium-effect filter, for multi-layer filtration.

[0004] Although the prior art can effectively improve the filtering and separation effect of the device on particulate matter in the air by setting up multi-layer filtration, the dust content in the outdoor environment fluctuates greatly at different times, resulting in that when the dust content in the environment is low, only the coarse-effect filter is required to perform filtering and separation operations, and the medium-efficiency filter is performing filtering and separation operations at the same time, which causes additional resistance to air flow and reduces the filtering efficiency of the device. In addition, the replacement frequency of the medium-efficiency filter is increased, thereby increasing the maintenance cost. Therefore, in response to the above problems, a filter intelligent adjustment structure and an air purifier with a photovoltaic panel are proposed. Summary of the invention

[0032] Working principle: When it is necessary to purify the outdoor air, start the exhaust fan to move the air in the environment into the filter chamber 1, so that the air passes through the drying layer 3 and the first filter 4, completes the drying and filtering process, and thus achieves air purification; When the dust content in the air increases, the gravity sensor detects that the weight change of the first filter 4 within a period of time exceeds a predetermined threshold value. At this time, the gravity sensor sends a signal to control the motor 10 to start, so that the motor 10 drives the driving gear 9 to rotate, the driving gear 9 drives the first lifting rack 8 to move, the first lifting rack 8 drives the first connecting block 7 to move away from the filter chamber 1, the first connecting block 7 drives the first sealing block 5 to move, the first sealing block 5 drives the first filter 4 to move, so that the first filter 4 is moved into the dustproof chamber 29, and at the same time, the driving gear 9 drives the second lifting rack 11 to move in the direction close to the filter chamber 1, the second lifting rack 11 drives the second connecting block 12 to move, the second connecting block 12 drives the second sealing block 13 to move, the second sealing block 13 drives the second filter 14 to move, so that the second filter 14 moves into the filter chamber 1, completing the replacement of the first filter 4 and the second filter 14, and at the same time, the driving gear 9 drives the first driving rod 18 to rotate, the first driving rod 18 drives the synchronous belt 19 to rotate, the synchronous belt 19 drives the second driving rod 20 to rotate, and the second The driving rod 20 drives the first bevel gear 21 to rotate, the first bevel gear 21 drives the second bevel gear 22 to rotate, the second bevel gear 22 drives the third driving rod 23 to rotate, and the third driving rod 23 drives the first convex block 24 to rotate, so that the first convex block 24 intermittently abuts against one side of the sliding base 25 and drives the sliding base 25 to move. When the first convex block 24 abuts against the sliding base 25, the sliding base 25 moves in a direction close to the spring 26. At this time, the sliding base 25 squeezes the spring 26, causing the spring 26 to undergo elastic deformation. , accumulating elastic potential energy, and when the first convex block 24 stops contacting with the sliding base 25, the spring 26 releases the elastic potential energy, undergoes elastic deformation and pushes the sliding base 25 to reset, so that the sliding base 25 drives the drying layer 3 to vibrate, thereby improving the drying efficiency of the drying layer 3. At the same time, the first convex block 24 drives the fourth driving rod 34 to rotate, so that the fourth driving rod 34 drives the inclined cover 36 to move away from the dust storage box 38 through the second convex block 35, so that the dust shaken off the drying layer 3 can fall into the dust storage box 38 for dust collection; When the dust content in the air decreases, the gravity sensor detects that the weight change of the second filter 14 within a period of time decreases to below a predetermined threshold value. At this time, the gravity sensor sends a signal to control the motor 10 to start, so that the motor 10 drives the first filter 4 to move into the filter chamber 1 through the driving gear 9, the first lifting rack 8, the first connecting block 7 and the first sealing block 5. At the same time, the motor 10 drives the second filter 14 to move into the dustproof chamber 29 through the driving gear 9, the second lifting rack 11, the second connecting block 12 and the second sealing block 13, completing the replacement of the first filter 4 and the second filter 14, thereby improving the purification efficiency of the device; When the weather is clear, the photovoltaic panel 33 collects solar energy and converts it into electrical energy. At this time, the photovoltaic panel 33 transmits the electrical energy to the internal power supply through wires and stores it. When the direction of sunlight changes, the light sensor 31 detects that the intensity of sunlight decreases. At this time, the light sensor 31 sends a signal to control the adjustment base 32 to start, so that the adjustment base 32 drives the photovoltaic panel 33 to rotate, thereby improving the solar energy collection efficiency of the photovoltaic panel 33.
