DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0024] like Figures 1 to 11As shown, the present invention provides a technical solution, an automobile air conditioning filter for air purification, comprising a shell 1, an air inlet cavity 2 is provided on the inner wall of the shell 1, an air outlet cavity 3 is provided inside the shell 1 and below the air inlet cavity 2, a connecting groove 4 is provided inside the shell 1 and between the air outlet cavity 3 and the air inlet cavity 2, an air extraction pipe 5 is fixedly connected to the outer wall of the shell 1, one end of the air extraction pipe 5 extends to the inside of the air outlet cavity 3, the outer wall of the shell 1 is fixedly connected to a fixing frame 6, a motor 7 is fixedly connected to the bottom of the fixing frame 6, an output end of the motor 7 extends to the inside of the air inlet cavity 2 and is fixedly connected to a sleeve 8, a plurality of air inlets 9 are equidistantly provided on the outer wall of the sleeve 8, two sliding shafts 11 are symmetrically fixedly connected to the inner wall of the air inlet 9, the outer walls of the two sliding shafts 11 are both slidably connected to slide plates 10, and the two slide plates 10 are fixedly connected between them. A mounting plate 13, the inner wall of which is symmetrically provided with two filter layers 14, the outer wall of the sliding shaft 11 is sleeved with a first spring 12, the top of the first spring 12 is fixedly connected to the slide plate 10, the bottom of the first spring 12 is fixedly connected to the sleeve 8, a waste chamber 17 is provided inside the shell 1 and below the air inlet chamber 2, an empty groove is provided inside the shell 1 and between the air inlet chamber 2 and the waste chamber 17, a fixed 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 fixed block 18, a second spring 19 is fixedly connected inside the fixed block 18, the top of the second spring 19 is fixedly connected to the top block 20, the elastic force of the second spring 19 is greater than the elastic force of the first spring 12, an extrusion block 16 is fixedly connected to one side of the mounting plate 13, and the outer walls of the extrusion block 16 and the top block 20 are both arranged as symmetrical inclined surfaces.

[0025] Through the above technical solution, after the automobile air conditioner is started, air is extracted through the exhaust pipe 5 to draw outside air into the automobile. The air enters the housing 1 along the air inlet cavity 2 and is filtered when passing through the filter layer 14 to remove 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 rotating the air inlet 9. 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, so that the top block 20 moves downward and compresses the second spring 19. When the sleeve 8 rotates, the mounting plate 13 and the extrusion block 16 rotate. When the extrusion block 16 rotates to the position of the empty slot, the extrusion of the sleeve 8 is lost. Under the action of the second spring 19, the top block 20 is reset, and 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 into the sleeve 8, driving the mounting plate 13 and the filter layer 14 to move into the sleeve 8, pressing the first spring 12. After the extrusion block 16 passes through the top block 20, the extrusion of the top block 20 is lost. Under the action of the first spring 12, the mounting plate 13 and the filter layer 14 are driven to move downward and vibrate, thereby shaking off the dust, pollen, smoke particles, etc. adhered to the filter layer 14. The shaken-off dust, pollen, smoke particles, etc. enter the waste chamber 17 along the empty slot for collection.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] Through the above technical scheme, when the motor 7 is started, it drives the first pulley 29 to rotate, and drives the second pulley 31 to rotate through the first transmission belt 30, thereby rotating the first rotating shaft 26, and 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, so that the piston rod 25 moves to the right, and drives the piston plate 24 to move to the right, and cooperates with the two one-way valves 23 to extract the hot air in the engine compartment of the automobile into the exhaust 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, so that the piston rod 25 moves to the left, and drives the piston plate 24 to move to the left, and cooperates with the two one-way valves 23 to transport the hot air in the exhaust chamber 22 along the air delivery groove 21 to the air intake chamber 2, thus reciprocating. After the motor 7 is started, hot air can be continuously extracted from the engine compartment of the automobile to ensure that the filter layer 14 is in a dry state, and bacteria and viruses are prevented from breeding in the filter layer 14.

[0032] Specifically, the top and bottom of the inner wall of the air inlet cavity 2 are symmetrically fixedly connected with guide plates 58, and the two guide plates 58 are both configured to be arc-shaped.

[0033] Through the above technical solution, after the hot air enters the air inlet cavity 2, it flows along the curved surface of the guide plate 58, which facilitates the hot air to hit the filter layer 14, thereby improving the drying effect of the hot air on the filter layer 14, and the hot air is blocked by the curved surface of the guide plate 58 to prevent the hot air from diffusing to the outside of the shell 1.

[0034] Specifically, a storage chamber 36 is provided inside the shell 1 and located above the air inlet chamber 2, a feed port 60 is provided on the top of the shell 1, and the feed port 60 is communicated with the storage chamber 36, a feed pipe 37 is fixedly connected to the inside of the shell 1 and located at the bottom of the storage chamber 36, and the bottom of the feed pipe 37 extends to the inside of the waste chamber 17, and ventilation grooves 38 are provided on both sides of the feed pipe 37, and a first baffle 39 is slidably connected to the inner wall of the feed pipe 37 and located above the ventilation groove 38, and the inner wall of the feed pipe 37 and located at A second baffle 40 is slidably connected to the bottom of the ventilation slot 38, a second rotating shaft 41 is rotatably connected to the inner wall of the air inlet chamber 2 and is located 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, 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 an output end of the electric telescopic rod 44 is fixedly connected to the first baffle 39.

[0035] Through the above technical solution, activated carbon particles are loaded into the storage chamber 36 through the feed port 60, and the activated carbon particles naturally fall into the discharge pipe 37, and are blocked by the second baffle 40, so that the activated carbon particles remain in the discharge pipe 37. When the outside air enters the air intake chamber 2, it passes through the two ventilation slots 38. The activated carbon particles arranged in the discharge pipe 37 can further absorb the odor in the air. After the car 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 discharge pipe 37 to close the discharge pipe 37. While 39 moves, it drives the upper rack 43 to move to the left, causing the gear 42 to rotate counterclockwise, driving the lower rack 43 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 discharge pipe 37, thereby causing the activated carbon particles in the discharge pipe 37 to fall into the waste material chamber 17, and 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 chamber 36 can enter the discharge pipe 37 along it, thereby achieving the replacement of the activated carbon particles.

[0036] Specifically, the inner wall of the waste chamber 17 is slidably connected to a sealing plate 33, the top of the sealing plate 33 is set as a symmetrical inclined surface, the bottom of the sealing plate 33 is fixedly connected to a connecting plate 32, the connecting plate 32 is slidably connected to the shell 1, the bottom of the connecting plate 32 is fixedly connected to a third spring 35, the bottom of the third spring 35 is fixedly connected to the shell 1, the inner wall of the waste chamber 17 and located below the sealing plate 33 are symmetrically provided with two material discharge grooves 59, the outer wall of the connecting plate 32 is fixedly connected to a protrusion 34, the protrusion 34 is used in conjunction with the U-shaped frame 27, and the inner wall of the waste chamber 17 is rotatably connected to a cover plate 61.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] Through the above technical scheme, the ventilation opening 47 is blocked by a plurality of partitions 49 to prevent the fragrance of the perfumed liquid from volatilizing naturally when the car air conditioner is not in use. When the outside air enters the air outlet cavity 3, the air first passes through the connecting groove 4. The connecting groove 4 is used to make the extracted air more concentrated. After passing through the connecting groove 4, the air hits the fan blades 52, thereby driving the fan blades 52 to rotate, causing the fourth rotating shaft 50 to rotate, and driving the third pulley 53 to rotate. Through the second transmission belt 54, the fourth pulley 55 is driven to rotate, causing the third rotating shaft 48 to rotate, and driving a plurality of partitions 49 to rotate. The fragrance can be wrapped by two adjacent partitions 49. As the third rotating shaft 48 rotates, the fragrance can be continuously transported upward.

[0042] Specifically, a plurality of zigzag grooves 56 are equidistantly arranged on the top of the gas delivery groove 21 .

[0043] Through the above technical scheme, the hot air entering the gas delivery groove 21 flows along a plurality of zigzag grooves 56, so that the hot air can better heat the liquid accumulation cavity 45, and then heat the fragrant liquid in the liquid accumulation cavity 45. The heated fragrant liquid has a better volatilization effect, which makes it easier to provide sufficient fragrance in the car and improve the environment inside the car.

[0044] When in use, after the automobile air conditioner is started, air is sucked through the exhaust pipe 5 to draw outside air into the automobile. The air enters the housing 1 along the air inlet cavity 2 and is filtered when passing through the filter layer 14 to remove impurities such as dust, pollen, bacteria, and smoke particles in the air. The motor 7 is started to drive the sleeve 8 to rotate, so that the air inlet 9 rotates. 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, so that the top block 20 moves downward and compresses the second spring 19. When the sleeve 8 rotates, the mounting plate 13 and the extrusion block 16 rotate. When the extrusion block 16 rotates to the position of the empty slot, the extrusion of the sleeve 8 is lost. Under the action of the second spring 19, the top block 20 is reset, and as the sleeve 8 rotates, the top block 20 presses against the extrusion block 1 The inclined surface of the outer wall of 6, under the pressure of the top block 20, pushes the extrusion block 16 to move into the sleeve 8, drives the mounting plate 13 and the filter layer 14 to move into the sleeve 8, and compresses the first spring 12. When the extrusion block 16 passes through the top block 20, the extrusion of the top block 20 is lost. Under the action of the first spring 12, the mounting plate 13 and the filter layer 14 are driven to move downward and vibrate, thereby shaking off the dust, pollen, smoke particles, etc. adhered to the filter layer 14. The shaken dust, pollen, smoke particles, etc. enter the waste cavity 17 along the empty groove for collection. The guide plate 15 is set so that the air entering the sleeve 8 will not be discharged directly. The air is dispersed when circulating along the guide plate 15. The air can be filtered at the same time through a plurality of filter layers 14, thereby improving the air filtration efficiency. When the car is running, a lot of heat will be generated in the engine compartment. The intake pipe 57 is connected to the car engine compartment. When the motor 7 is started, it drives the first pulley 29 to rotate. Through the first transmission belt 30, the second pulley 31 is driven to rotate, so that the first rotating shaft 26 rotates, and the U-shaped frame 27 is driven to rotate. When the end of the U-shaped frame 27 rotates to the right, the connecting shaft 28 is driven to move to the right, so that the piston rod 25 moves to the right, and the piston plate 24 moves to the right. In cooperation with the two one-way valves 23, the hot air in the car engine compartment is pumped into the exhaust chamber 22. When the end of the U-shaped frame 27 rotates to the left, the connecting shaft 28 is pushed to move to the left, so that the piston rod 25 moves to the left, and the piston plate 24 moves to the left. The two one-way valves 23 are arranged in cooperation to convey the hot air in the air extraction chamber 22 along the air delivery groove 21 to the air inlet chamber 2, and thus reciprocate. After the motor 7 is started, the hot air can be continuously extracted from the automobile engine compartment to ensure that the filter layer 14 is in a dry state, and the filter layer 14 is prevented from breeding bacteria and viruses. After the hot air enters the air inlet chamber 2, it flows along the curved surface of the guide plate 58, which is convenient for the hot air to hit the filter layer 14, thereby improving the drying effect of the hot air on the filter layer 14, and the hot air is prevented from diffusing to the outside of the shell 1 through the blocking of the curved surface of the guide plate 58. Activated carbon particles are loaded into the storage chamber 36 through the feed port 60, and the activated carbon particles naturally fall into the discharge pipe 37, and are blocked by the second baffle 40, so that the activated carbon particles remain in the discharge pipe 37.When outside air enters the air intake chamber 2, it passes through the two ventilation slots 38, and can further absorb odors in the air through the activated carbon particles arranged in the discharge pipe 37. After the automobile 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 discharge pipe 37 to close the discharge pipe 37. When the first baffle 39 moves, it drives the upper rack 43 to move to the left, so that the gear 42 rotates counterclockwise, drives the lower rack 43 to move to the right, and moves the second baffle 40 to the right. After the second baffle 40 moves, it no longer blocks the activated carbon particles in the discharge pipe 37, thereby allowing the activated carbon particles in the discharge pipe 37 to fall into the waste chamber 17, and then the electric telescopic rod 44 is retracted to allow the first baffle 39 and the discharge pipe 37 to close. After the second baffle 40 is reset and the first baffle 39 is reset, the activated carbon particles in the storage chamber 36 can enter the discharge pipe 37, thereby achieving the replacement of the activated carbon particles. The sealing plate 33 is provided to block the falling dust, pollen, smoke particles and activated carbon particles. The dust, pollen, smoke particles and activated carbon particles slide 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 discharge chute 59, and the dust, pollen, smoke particles and activated carbon particles fall along the discharge chute 59 to the bottom of the sealing plate 33, and the connecting plate 3 2 moves downward, compressing the third spring 35. As the U-shaped frame 27 rotates, its end is separated from the protrusion 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 to the top of the feeding chute 59. The sealing plate 33 blocks dust, pollen, smoke particles and activated carbon particles to prevent the dust, pollen, smoke particles and activated carbon particles from emitting odors and affecting the air quality in the vehicle. The fragrance liquid is injected into the liquid accumulation chamber 45 through the filling pipe 62, and the fragrance liquid is absorbed by the sponge pad 46 to prevent the fragrance liquid from shaking continuously in the liquid accumulation chamber 45 when the vehicle is driving. The fragrance emitted by the fragrance liquid enters the air outlet chamber 3 along the vent 47, and the ventilation holes 47 are blocked by the plurality of partitions 49. The air vent 47 is blocked to prevent the fragrance of the perfume liquid from volatilizing naturally when the car air conditioner is not in use. When the outside air enters the air outlet cavity 3, the air first passes through the connecting groove 4. The connecting groove 4 is provided to make the extracted air more concentrated. After passing through the connecting groove 4, the air hits the fan blade 52, thereby driving the fan blade 52 to rotate, so that the fourth rotating shaft 50 rotates, and the third pulley 53 rotates. The fourth pulley 55 is driven to rotate through the second transmission belt 54, so that the third rotating shaft 48 rotates, and the plurality of partitions 49 rotate. The fragrance can be wrapped by two adjacent partitions 49. With the rotation of the third rotating shaft 48, the fragrance can be continuously transported upward. The hot air entering the air delivery groove 21 flows along the plurality of zigzag grooves 56.Thus, the hot air can better heat the liquid accumulation chamber 45, and then heat the fragrance liquid in the liquid accumulation chamber 45, and the heated fragrance liquid has a better volatilization effect, thereby facilitating the provision of sufficient fragrance in the car and improving the environment in the car.
