Detailed implementation manners

[0035] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0036] As Figures 1 to 11As shown in the figure, the present invention provides a technical solution, an automotive air conditioner filter for air purification, which includes a housing 1. An air inlet chamber 2 is formed on the inner wall of the housing 1. An air outlet chamber 3 is formed below the air inlet chamber 2 inside the housing 1. A communication groove 4 is formed between the air outlet chamber 3 and the air inlet chamber 2 inside the housing 1. An air extraction pipe 5 is fixedly connected to the outer wall of the housing 1. One end of the air extraction pipe 5 extends into the air outlet chamber 3. A fixing frame 6 is fixedly connected to the outer wall of the housing 1. A motor 7 is fixedly connected to the bottom of the fixing frame 6. The output end of the motor 7 extends into the air inlet chamber 2 and is fixedly connected with a sleeve 8. A plurality of air inlets 9 are equidistantly formed on the outer wall of the sleeve 8. Two sliding shafts 11 are symmetrically and fixedly connected to the inner wall of the air inlet 9. Slide plates 10 are slidably connected to the outer walls of the two sliding shafts 11. A mounting plate 13 is fixedly connected between the two slide plates 10. Two filter layers 14 are symmetrically arranged on the inner wall of the mounting plate 13. A first spring 12 is sleeved on the outer wall of the sliding shaft 11. The top of the first spring 12 is fixedly connected with the slide plate 10. The bottom of the first spring 12 is fixedly connected with the sleeve 8. A waste material chamber 17 is formed below the air inlet chamber 2 inside the housing 1. An empty groove is formed between the air inlet chamber 2 and the waste material chamber 17 inside the housing 1. A fixing block 18 is fixedly connected to the inner wall of the empty groove. A top block 20 is slidably connected to the inner wall of the fixing block 18. A second spring 19 is fixedly connected to the inside of the fixing block 18. The top of the second spring 19 is fixedly connected with the top block 20. The elastic force of the second spring 19 is greater than that of the first spring 12. One side of the mounting plate 13 is fixedly connected with a pressing block 16. The outer walls of the pressing block 16 and the top block 20 are both provided with symmetric inclined surfaces.

[0037] Through the above technical solution, after the automotive air conditioner is started, air is extracted through the air extraction pipe 5, and the outside air is drawn into the vehicle. The air enters the housing 1 along the air inlet chamber 2 and is filtered when passing through the filter layer 14, removing impurities such as dust, pollen, bacteria, and smoke particles in the air. The motor 7 is started, and the motor 7 drives the sleeve 8 to rotate, thereby causing the air inlet 9 to rotate. When the air inlet 9 rotates to the position of the top block 20, it presses against the inclined surface of the outer wall of the top block 20, causing the top block 20 to move downward and compressing the second spring 19. While the sleeve 8 rotates, the mounting plate 13 and the pressing block 16 also rotate. When the pressing block 16 rotates to the position of the empty groove, it loses the extrusion of the sleeve 8. Under the action of the second spring 19, the top block 20 resets. As the sleeve 8 rotates, the top block 20 presses against the inclined surface of the outer wall of the pressing block 16. Under the extrusion of the top block 20, the pressing block 16 is pushed to move into the sleeve 8, driving the mounting plate 13 and the filter layer 14 to move into the sleeve 8 and compressing the first spring 12. When the pressing block 16 passes through the top block 20, it loses the extrusion of the top block 20. Under the action of the first spring 12, it drives the mounting plate 13 and the filter layer 14 to move downward and vibrate, thereby shaking off the dust, pollen, smoke particles, etc. adhering to the filter layer 14. The shaken-off dust, pollen, smoke particles, etc. enter the waste material chamber 17 along the empty groove for collection.

[0038] Specifically, two guide plates 15 are symmetrically fixedly connected to the other side of the mounting plate 13 , and the two guide plates 15 are both arranged in an arc shape.

[0039] Through the above technical solution, the guide plate 15 is set to prevent the air entering the sleeve 8 from being directly discharged. The air is dispersed when flowing along the guide plate 15, and can be filtered simultaneously through several filter layers 14, thereby improving the air filtering effect.

[0040] Specifically, an air delivery groove 21 is provided inside the shell 1, and the top of the air delivery groove 21 is communicated with the air inlet chamber 2. An air inlet pipe 57 is fixedly connected to the outer wall of the shell 1, and one end of the air inlet pipe 57 extends to the inside of the air delivery groove 21. An air extraction chamber 22 is provided inside the shell 1, and one side of the air extraction chamber 22 is communicated with the air delivery groove 21. A piston plate 24 is slidably connected to the inner wall of the air extraction chamber 22. Two one-way valves 23 are symmetrically provided on the inner wall of the air delivery groove 21 with the piston plate 24 as the center. Both one-way valves 23 are opened in the direction of the air inlet chamber 2, and a piston rod 25 is fixedly connected to one side of the piston plate 24. An air extraction component is provided inside the shell 1.

[0041] Through the above technical solution, a large amount of heat is generated in the engine compartment when the car is driving. The air intake pipe 57 is connected to the car engine compartment, and the hot air in the car engine compartment is pumped into the air delivery groove 21 through the air extraction component. The hot air flows along the air delivery groove 21 to the air intake cavity 2, and flows along the air intake cavity 2 to heat the filter layer 14, thereby solving the problem that the filter layer 14 absorbs a large amount of moisture and is too humid, and the hot air entering the sleeve 8 is blocked by the guide plate 15, which can further extend the residence time at the filter layer 14 and improve the drying effect of the filter layer 14.

[0042] Specifically, the vacuum assembly includes two first rotating shafts 26, which are symmetrically connected to the inside of the shell 1, a U-shaped frame 27 is fixedly connected between the two first rotating shafts 26, and the outer wall of the U-shaped frame 27 is rotatably connected to a connecting shaft 28, one end of the connecting shaft 28 is rotatably connected to the piston rod 25, one end of one of the first rotating shafts 26 passes through the shell 1 and is fixedly connected to a second pulley 31, and the outer wall of the output end of the motor 7 is fixedly connected to a first pulley 29, and the first pulley 29 and the second pulley 31 are connected for transmission through a first transmission belt 30.

[0043] Through the above technical solution, when the motor 7 starts, it drives the first pulley 29 to rotate. The first transmission belt 30 drives the second pulley 31 to rotate, thereby causing the first rotating shaft 26 to rotate. The first rotating shaft 26 drives the U-shaped frame 27 to rotate. When the end of the U-shaped frame 27 rotates to the right, it drives the connecting shaft 28 to move to the right, causing the piston rod 25 to move to the right, driving the piston plate 24 to move to the right. Cooperating with the two check valves 23 provided, the hot air in the automobile engine compartment is pumped into the air extraction chamber 22. When the end of the U-shaped frame 27 rotates to the left, it pushes the connecting shaft 28 to move to the left, causing the piston rod 25 to move to the left, driving the piston plate 24 to move to the left. Cooperating with the two check valves 23 provided, the hot air in the air extraction chamber 22 is conveyed along the air delivery groove 21 to the air inlet chamber 2. Thus, reciprocatingly, after the motor 7 starts, it can continuously extract hot air from the automobile engine compartment, ensuring that the filter layer 14 is in a dry state and preventing bacteria and viruses from breeding on the filter layer 14.

[0044] Specifically, the top and bottom of the inner wall of the air inlet chamber 2 are symmetrically and fixedly connected with diversion plates 58, and both diversion plates 58 are arranged in an arc shape.

[0045] Through the above technical solution, after the hot air enters the air inlet chamber 2, it flows along the arc surface of the diversion plate 58, which is convenient for the hot air to impact on the filter layer 14, improving the drying effect of the hot air on the filter layer 14. And due to the blockage of the arc surface of the diversion plate 58, the hot air is prevented from diffusing to the outside of the housing 1.

[0046] Specifically, a stockpiling chamber 36 is provided inside the housing 1 and above the air inlet chamber 2. A feed port 60 is provided at the top of the housing 1, and the feed port 60 communicates with the stockpiling chamber 36. A blanking pipe 37 is fixedly connected to the bottom of the stockpiling chamber 36 inside the housing 1, and the bottom of the blanking pipe 37 extends into the waste chamber 17. Ventilation grooves 38 are provided on both sides of the blanking pipe 37. A first baffle 39 is slidably connected to the inner wall of the blanking pipe 37 above the ventilation grooves 38, and a second baffle 40 is slidably connected to the inner wall of the blanking pipe 37 below the ventilation grooves 38. A second rotating shaft 41 is rotatably connected to the inner wall of the air inlet chamber 2 between the first baffle 39 and the second baffle 40. A gear 42 is fixedly connected to the outer wall of the second rotating shaft 41. A rack 43 is fixedly connected to the bottom of the first baffle 39 and the top of the second baffle 40, and both racks 43 are meshed with the gear 42. An electric telescopic rod 44 is fixedly connected to the inner wall of the air inlet chamber 2, and the output end of the electric telescopic rod 44 is fixedly connected to the first baffle 39.

[0047] Through the above technical solution, activated carbon particles are loaded into the storage cavity 36 through the feed inlet 60. The activated carbon particles naturally fall into the feed pipe 37 and are blocked by the second baffle 40, so that the activated carbon particles stay in the feed pipe 37. When external air enters the air inlet cavity 2, it passes through the two ventilation grooves 38. By means of the activated carbon particles arranged in the feed pipe 37, the peculiar smell in the air can be further adsorbed. After the automotive air conditioner is used for a long time, the electric telescopic rod 44 is started to push the first baffle 39 to move into the feed pipe 37 to close the feed pipe 37. While the first baffle 39 moves, it drives the upper rack 43 to move to the left, making the gear 42 rotate counterclockwise, driving the lower rack 43 to move to the right, and making the second baffle 40 move to the right. After the second baffle 40 moves, it no longer blocks the activated carbon particles in the feed pipe 37, so that the activated carbon particles in the feed pipe 37 fall into the waste cavity 17. Then the electric telescopic rod 44 is retracted to reset the first baffle 39 and the second baffle 40. After the first baffle 39 is reset, the activated carbon particles in the storage cavity 36 can enter the feed pipe 37 along the way, thus realizing the replacement of the activated carbon particles.

[0048] Specifically, a sealing plate 33 is slidably connected to the inner wall of the waste cavity 17. The top of the sealing plate 33 is provided with symmetric inclined surfaces. The bottom of the sealing plate 33 is fixedly connected with a connecting plate 32. The connecting plate 32 is slidably connected to the housing 1. The bottom of the connecting plate 32 is fixedly connected with a third spring 35. The bottom of the third spring 35 is fixedly connected with the housing 1. Two discharge grooves 59 are symmetrically formed in the inner wall of the waste cavity 17 and below the sealing plate 33. A convex block 34 is fixedly connected to the outer wall of the connecting plate 32. The convex block 34 is used in cooperation with the U-shaped frame 27. A cover plate 61 is rotatably connected to the inner wall of the waste cavity 17.

[0049] Through the above technical solution, the provided sealing plate 33 blocks the falling dust, pollen, smoke particles and activated carbon particles, and the dust, pollen, smoke particles and activated carbon particles slide down along the inclined surface at the top of the sealing plate 33 and accumulate at the angle between the sealing plate 33 and the waste chamber 17. While the U-shaped frame 27 rotates, its end pushes the protrusion 34 to move downward, so that the connecting plate 32 moves downward, driving the sealing plate 33 to move downward. After the sealing plate 33 moves downward, it passes through the feed chute 59, and the dust, pollen, smoke particles and activated carbon particles fall along the feed chute 59 to the bottom of the sealing plate 33, and the connecting plate 32 While moving downward, the third spring 35 is compressed. As the U-shaped frame 27 rotates, its end separates from the protrusion 34, and the connecting plate 32 moves upward under the action of the third spring 35, thereby driving the sealing plate 33 to move upward, so that the sealing plate 33 moves to the top of the discharge chute 59. The sealing plate 33 blocks dust, pollen, smoke particles and activated carbon particles to prevent them from emitting odors and affecting the air quality in the vehicle. The waste chamber 17 can be opened by rotating the cover plate 61 to clean the dust, pollen, smoke particles and activated carbon particles accumulated inside.

[0050] Specifically, a liquid accumulation chamber 45 is opened inside the shell 1 and below the vacuum chamber 22, a filling pipe 62 is fixedly connected to the outer wall of the shell 1, one end of the filling pipe 62 extends to the inside of the liquid accumulation chamber 45, a sponge pad 46 is arranged inside the liquid accumulation chamber 45, a vent 47 is opened inside the shell 1 and between the liquid accumulation chamber 45 and the air outlet chamber 3, and an air outlet unit is arranged inside the vent 47.

[0051] Through the above technical solution, scented liquid is injected into the liquid accumulation chamber 45 through the filling pipe 62, and the scented liquid is absorbed by the sponge pad 46 to prevent the scented liquid from continuously shaking in the liquid accumulation chamber 45 when the vehicle is driving. The fragrance emitted by the scented liquid enters the air outlet chamber 3 along the vent 47, and the emission of the fragrance is controlled by the air outlet unit. After the car air conditioner is turned on, the fragrance can automatically enter the car to improve the air quality in the car.

[0052] Specifically, the air outlet unit includes a third rotating shaft 48, which is rotatably connected to the inner wall of the vent 47, and a plurality of partitions 49 are equidistantly fixedly connected to the outer wall of the third rotating shaft 48, and the partitions 49 fit the inner wall of the vent 47. The inner wall of the air outlet cavity 3 is rotatably connected to a fourth rotating shaft 50, and a sleeve 51 is fixedly connected to one end of the fourth rotating shaft 50, and a plurality of fan blades 52 are equidistantly fixedly connected to the outer wall of the sleeve 51, and the fan blades 52 are installed at an angle, and a third pulley 53 is fixedly connected to the outer wall of the fourth rotating shaft 50, and a fourth pulley 55 is fixedly connected to the outer wall of the third rotating shaft 48, and the third pulley 53 and the fourth pulley 55 are connected for transmission via a second transmission belt 54.

[0053] Through the above technical solution, a number of partition plates 49 are provided to block the ventilation openings 47, preventing the natural volatilization of the fragrance of the perfume when the automotive air conditioner is not in use. When external air enters the air outlet cavity 3, the air first passes through the communication grooves 4. The communication grooves 4 are provided to make the extracted air more concentrated. After the air passes through the communication grooves 4, it impacts on the fan blades 52, thereby driving the fan blades 52 to rotate, causing the fourth rotating shaft 50 to rotate, driving the third pulley 53 to rotate. Through the provided second transmission belt 54, the fourth pulley 55 is driven to rotate, causing the third rotating shaft 48 to rotate, driving a number of partition plates 49 to rotate. The fragrance can be wrapped by two adjacent partition plates 49. With the rotation of the third rotating shaft 48, the fragrance can be continuously conveyed upward.

[0054] Specifically, a number of zigzag grooves 56 are equidistantly arranged at the top of the air delivery groove 21.

[0055] Through the above technical solution, the hot air entering the air delivery groove 21 flows along a number of zigzag grooves 56, so that the hot air can better heat the liquid accumulation cavity 45, and then heat the perfume in the liquid accumulation cavity 45. The volatilization effect of the heated perfume is better, which is convenient for providing sufficient fragrance in the vehicle and improving the vehicle environment.

[0056] When in use, after the automotive air conditioner is started, it begins to draw air through the air suction pipe 5, sucking outside air into the vehicle. The air enters the housing 1 along the air intake cavity 2 and is filtered when passing through the filter layer 14, removing impurities such as dust, pollen, bacteria, and smoke particles in the air. The motor 7 is started to drive the sleeve 8 to rotate, causing the air inlet 9 to rotate. When the air inlet 9 rotates to the position of the top block 20, it presses against the inclined surface of the outer wall of the top block 20, causing the top block 20 to move downward, compressing the second spring 19. While the sleeve 8 rotates, the mounting plate 13 and the extrusion block 16 also rotate. When the extrusion block 16 rotates to the position of the empty slot, it loses the extrusion of the sleeve 8. Under the action of the second spring 19, the top block 20 returns to its original position. As the sleeve 8 rotates, the top block 20 presses against the inclined surface of the outer wall of the extrusion block 16. Under the extrusion of the top block 20, the extrusion block 16 is pushed to move inward into the sleeve 8, driving the mounting plate 13 and the filter layer 14 to move inward into the sleeve 8, compressing the first spring 12. When the extrusion block 16 passes through the top block 20, it loses the extrusion of the top block 20. Under the action of the first spring 12, it drives the mounting plate 13 and the filter layer 14 to move downward and vibrate, thereby shaking off the dust, pollen, smoke particles, etc. adhering to the filter layer 14. The shaken-off dust, pollen, smoke particles, etc. enter the waste material cavity 17 along the empty slot for collection. Through the provided flow guide plate 15, the air entering the sleeve 8 will not be directly discharged. When the air flows along the flow guide plate 15, it scatters in all directions. The air can be filtered simultaneously through several filter layers 14, improving the air filtration effect. When the vehicle is driving, a large amount of heat is generated in the engine compartment. The intake pipe 57 is connected to the vehicle engine compartment. When the motor 7 is started, it drives the first pulley 29 to rotate. Through the provided first transmission belt 30, it drives the second pulley 31 to rotate, causing the first rotating shaft 26 to rotate, driving the U-shaped frame 27 to rotate. When the end of the U-shaped frame 27 rotates to the right side, it drives the connecting shaft 28 to move to the right side, causing the piston rod 25 to move to the right side, driving the piston plate 24 to move to the right side. Cooperating with the two check valves 23 provided, the hot air in the vehicle engine compartment is drawn into the air suction cavity 22. When the end of the U-shaped frame 27 rotates to the left side, it pushes the connecting shaft 28 to move to the left side, causing the piston rod 25 to move to the left side, driving the piston plate 24 to move to the left side. Cooperating with the two check valves 23 provided, the hot air in the air suction cavity 22 is conveyed along the air delivery groove 21 to the air intake cavity 2. Thus, it reciprocates. After the motor 7 is started, it can continuously extract hot air from the vehicle engine compartment, ensuring that the filter layer 14 is in a dry state, avoiding the growth of bacteria and viruses on the filter layer 14. After the hot air enters the air intake cavity 2, it flows along the arc surface of the drainage plate 58, facilitating the hot air to impact on the filter layer 14 and improving the drying effect of the hot air on the filter layer 14. And through the blocking of the arc surface of the drainage plate 58, the hot air is prevented from diffusing to the outside of the housing 1. Activated carbon particles are loaded into the storage cavity 36 through the feed port 60. The activated carbon particles naturally fall into the feed pipe 37 and are blocked by the second baffle 40, causing the activated carbon particles to stay in the feed pipe 37.When the outside air enters the intake cavity 2, it passes through the two ventilation slots 38 and through the activated carbon particles provided in the blanking pipe 37, which can further adsorb the odor in the air. After the automotive air conditioner has been used for a long time, the electric telescopic rod 44 is activated to push the first baffle 39 into the blanking pipe 37 to close the blanking pipe 37. While the first baffle 39 moves, it drives the rack 43 above to move to the left, causing the gear 42 to rotate counterclockwise, driving the rack 43 below to move to the right, causing the second baffle 40 to move to the right. After the second baffle 40 moves, it no longer blocks the activated carbon particles in the blanking pipe 37, so that the activated carbon particles in the blanking pipe 37 fall into the waste cavity 17. Subsequently, the electric telescopic rod 44 is retracted to reset the first baffle 39 and the second baffle 40. After the first baffle 39 is reset, the activated carbon particles in the storage cavity 36 can enter the blanking pipe 37, thus achieving the replacement of the activated carbon particles. The falling dust, pollen, smoke particles and activated carbon particles are blocked by the provided sealing plate 33, and the dust, pollen, smoke particles and activated carbon particles slide down along the inclined surface at the top of the sealing plate 33 and accumulate at the angle between the sealing plate 33 and the waste cavity 17. While the U-shaped frame 27 rotates, its end pushes the convex block 34 downward, causing the connecting plate 32 to move downward, driving the sealing plate 33 to move downward. After the sealing plate 33 moves downward and passes through the blanking slot 59, the dust, pollen, smoke particles and activated carbon particles fall along the blanking slot 59 to the lower side of the sealing plate 33. While the connecting plate 32 moves downward, it compresses the third spring 35. As the U-shaped frame 27 rotates and its end separates from the convex block 34, under the action of the third spring 35, the connecting plate 32 moves upward, driving the sealing plate 33 to move upward, so that the sealing plate 33 moves above the blanking slot 59. The sealing plate 33 blocks the dust, pollen, smoke particles and activated carbon particles to prevent the dust, pollen, smoke particles and activated carbon particles from emitting odor again and affecting the air quality in the vehicle. Perfume is injected into the liquid storage cavity 45 through the filling pipe 62, and the sponge pad 46 absorbs the perfume to prevent the perfume from continuously shaking in the liquid storage cavity 45 when the vehicle is driving. The fragrance emitted by the perfume enters the air outlet cavity 3 along the ventilation port 47. The provided plurality of partition plates 49 block the ventilation port 47 to prevent the fragrance of the perfume from volatilizing naturally when the automotive air conditioner is not in use. When the outside air enters the air outlet cavity 3, the air first passes through the communication slot 4. Through the provided communication slot 4, the extracted air is more concentrated. After the air passes through the communication slot 4, it impacts on the fan blade 52, thereby driving the fan blade 52 to rotate, causing the fourth rotating shaft 50 to rotate, driving the third belt pulley 53 to rotate. Through the provided second transmission belt 54, the fourth belt pulley 55 is driven to rotate, causing the third rotating shaft 48 to rotate, driving the plurality of partition plates 49 to rotate. The fragrance can be wrapped by two adjacent partition plates 49. As the third rotating shaft 48 rotates, the fragrance can be continuously conveyed upward. The hot air entering the air delivery groove 21 flows along a plurality of zigzag grooves 56,Thus, the hot air can better heat the liquid accumulation cavity 45, and then heat the perfume liquid in the liquid accumulation cavity 45. The volatilization effect of the heated perfume liquid is better, so it is convenient to provide sufficient fragrance in the car and improve the environment in the car.
