[0040] The present invention will be further described in detail below with reference to the drawings and specific embodiments, and the scope of implementation of the present invention is not limited thereto.

[0041] As Figures 1 to 14 shown, an antiviral automotive air conditioner filter described in this embodiment includes a housing 1 and a first filter layer movably disposed within the housing 1;

[0042] One side of the housing 1 is provided with an air inlet 11, the other side is provided with an air outlet 12 and a wind deflector 3 which is slidably arranged to block the air outlet 12; a first spring 31 is arranged between the wind deflector 3 and the housing 1; inside the housing 1, a first sliding groove 13 is arranged between the first filter layer and the wind deflector 3, a push rod 32 is slidably arranged in the first sliding groove 13, and an elastic floating protrusion 33 which protrudes into the first sliding groove 13 and abuts against the push rod 32 is arranged on one side of the wind deflector 3 facing the first filter layer; the first filter layer includes a first sliding seat 21 slidably arranged on the top inside the housing 1, a second spring 22 is arranged between the first sliding seat 21 and the housing 1, and a convex platform 211 is arranged at the position of the first sliding seat 21 corresponding to the first sliding groove 13;

[0043] When the first sliding seat 21 slides towards the wind deflector 3 against the elastic force of the second spring 22, the convex platform 211 protrudes into the first sliding groove 13, so that the push rod 32 squeezes the latch 33 out of the first sliding groove 13.

[0044] Specifically, when the automotive air filter described in this embodiment is actually used, the first filter layer is placed between the air inlet 11 and the air outlet 12, and the first filter layer works to filter the air. As the amount of pollutants adsorbed by the first filter layer increases, the air inlet resistance of the first filter layer increases, that is, the permeability of the first filter layer decreases. Under the action of wind force, the first sliding seat 21 slides towards the air outlet 12 direction, the first sliding seat 21 squeezes the second spring 22, the convex platform 211 is inserted into the first sliding groove 13, and pushes the push rod 32 to slide in the first sliding groove 13. During the sliding process of the push rod 32, the push rod 32 squeezes the latch 33, so that the latch 33 slides against the elastic force until the latch 33 completely moves out of the first sliding groove 13, the latch 33 releases the support for the wind deflector 3, so that the wind deflector 3 slides under the elastic force of the first spring 31 and blocks the air outlet 12. In this way, a trigger signal is generated by the sliding of the wind deflector 3, so as to achieve the function of reminding to replace the filter element.

[0045] This embodiment utilizes the decrease in the permeability of the filter element, so that the first filter layer slides under the action of wind force, the convex platform 211 is used to push the push rod 32 to slide, the push rod 32 squeezes the latch 33, so that the wind deflector 3 slides under the action of the first spring 31, thereby realizing the generation of a trigger signal by the sliding of the wind deflector 3, achieving the function of reminding to replace the filter element, avoiding the breeding of viruses caused by long-term use, and having an antiviral effect.

[0046] Such as Figure 1 、 Figures 4 to 6As shown, for the automotive air conditioner filter described in this embodiment, in some embodiments, both ends of the first sliding seat 21 are elastically and floatingly connected with first hanging pins 212, and first hanging holes 14 for cooperating with the first hanging pins 212 are provided in the housing 1; the first filter layer further includes a first filter net 23, a first winding roller 4 is rotatably provided in the housing 1, a first torsion spring 41 is connected between the first winding roller 4 and the housing 1, one end of the first filter net 23 is connected to the first winding roller 4, the other end of the first filter net 23 is provided with a first hanging ear 242, and a first hook structure is movably clamped in the first sliding seat 21; when the first filter layer is in the unfolded state, the first hanging ear 242 is hooked on the first hook structure.

[0047] Specifically, the first hanging pin 212 is movably inserted into the first hanging hole 14. When the air inlet resistance of the first filter layer increases, the first sliding seat 21 slides towards the air outlet 12 direction against the elastic force of the second spring 22, and the first hanging pin 212 slides in the first hanging hole 14. Initially, the first filter net 23 is wound around the first winding roller 4. When the first winding roller 4 unwinds against the torque of the first torsion spring 41, the first filter net 23 unfolds towards the first sliding seat 21 direction until the first filter net 23 is hooked on the first sliding seat 21 through the cooperation of the first hanging ear 242 and the first hook structure. At this time, the first filter net 23 is in the fully unfolded state.

[0048] As Figure 6 shown, for the automotive air conditioner filter described in this embodiment, in some embodiments, the first hook structure includes a slider 2131, a hook 2132 and a third spring 2133. The first sliding seat 21 is provided with a second chute 214 and a hanging slot 215. Both ends of the second chute 214 are provided with two second hanging holes 216; the slider 2131 is slidably arranged in the second chute 214, the third spring 2133 is connected between the slider 2131 and the first sliding seat 21, both ends of the slider 2131 are floatingly connected with second hanging pins 2134 for cooperating with the second hanging holes 216, a fourth spring 2135 is connected between the second hanging pin 2134 and the slider 2131, one end of the hook 2132 is slidably arranged in the slider 2131, a fifth spring 2136 is connected between one end of the hook 2132 and the slider 2131, and the stiffness of the fifth spring 2136 is less than that of the fourth spring 2135; the other end of the hook 2132 protrudes into the hanging slot 215.

[0049] Specifically, through the cooperation of the first hanging pin 212 and the first hanging hole 14, the first sliding seat 21 is slidably hung inside the housing 1. The first filter screen 23 is wound around the first winding roller 4 under the action of the first torsion spring 41. When the first winding roller 4 unwinds, the first filter screen 23 gradually unfolds. When the first hanging ear 242 extends into the hanging slot 215, since the stiffness of the fifth spring 2136 is less than that of the fourth spring 2135, the two hooks 2132 slide towards the center respectively by overcoming the elastic force of the fifth spring 2136 to be clamped with the first hanging ear 242. After the first hanging ear 242 is clamped with the hooks 2132, as the first filter screen 23 continues to move upward, the first hanging ear 242 generates a thrust on the slider 2131 through the hooks 2132, so that the second hanging pin 2134 moves out of the second hanging hole 216 by overcoming the elastic force of the fourth spring 2135. At this time, the slider 2131 can slide upward along the second chute 214 under the elastic force of the third spring 2133. When the first filter screen 23 abuts against the first sliding seat 21, the second hanging pin 2134 corresponds to the second hanging hole 216 located above. The second hanging pin 2134 is inserted into the second hanging hole 216 under the elastic force of the fourth spring 2135, thereby positioning the position of the slider 2131. At this time, the hanging of the first filter screen 23 on the first sliding seat 21 is completed. At this time, the first filter screen layer is in an unfolded state, that is, the first filter screen layer is in a working state.

[0050] As Figures 1 to 4 shown, in the automotive air filter described in this embodiment, in some embodiments, a second filter screen layer is also movably provided inside the housing 1 on the side close to the air inlet 11. A traction assembly is connected between the second filter screen layer and the first filter screen layer, so that when the second filter screen layer is in an unfolded state, the first filter screen layer is in a wound state, and when the second filter screen layer is in a wound state, the first filter screen layer is in an unfolded state.

[0051] Specifically, initially, when the second filter screen layer is in an unfolded state, the first filter screen layer is in a wound state. As the air entering from the air inlet 11 passes through the second filter screen layer and flows out from the air outlet 12, with the use time of the second filter screen layer, the amount of pollutants adsorbed by the second filter screen layer increases and the permeability decreases. At this time, the second filter screen layer is placed in a wound state, and under the linkage of the traction assembly, the traction assembly generates a pulling force on the second filter screen layer, so that the first winding roller 4 unwinds by overcoming the torsion of the first torsion spring 41, thereby realizing the automatic replacement of the filter screen layer once to ensure the air filtration effect.

[0052] As Figures 1 to 4 、 Figures 9 to 13As shown, for the automotive air filter described in this embodiment, in some embodiments, the second filter layer includes a second sliding seat 51 and a second filter screen 52. A second winding roller 7 is rotatably provided in the housing 1. A second torsion spring 71 is connected between the second winding roller 7 and the housing 1. The stiffness of the second torsion spring 71 is greater than that of the first torsion spring 41. The second sliding seat 51 is slidably provided in the housing 1. A sixth spring 53 is connected between the second sliding seat 51 and the housing 1. Third hanging pins 511 are elastically and floatingly connected to both ends of the second sliding seat 51. A third hanging hole 15 for cooperating with the second hanging pin 2134 is provided in the housing 1;

[0053] The second sliding seat 51 is provided with a first receiving groove. A third hanging ear 512 is movably inserted into the upper end of the first receiving groove of the second sliding seat 51. The housing 1 is provided with an L-shaped second hook structure 16 at a position corresponding to the third hanging ear 512. One end of the second filter screen 52 is connected to the second winding roller 7, and the other end of the second filter screen 52 is connected to the second sliding seat 51;

[0054] One end of the traction assembly movably passes through the first sliding seat 21 and is then connected to the other end of the first filter screen 23. The other end of the traction assembly is fixedly connected to the second sliding seat 51.

[0055] Specifically, through the third hanging pin 511 and the third hanging hole 15, the second sliding seat 51 is slidably hung on the housing 1. At this time, the second filter screen 52 is in an unfolded state. The position of the second hook structure 16 corresponds to that of the first receiving groove, and the second torsion spring 71 is in a deformed state. As the pollutants adsorbed on the second filter screen 52 increase, the air inlet resistance of the second filter screen 52 increases. The second filter screen 52 drives the second sliding seat 51 to slide under the action of wind. The second sliding seat 51 drives the third hanging ear 512 to move, and the sixth spring 53 is compressed, so that the bottom surface of the third hanging ear 512 contacts the top surface of the longitudinal arm of the second hook structure 16. The third hanging ear 512 slides along the top surface of the longitudinal arm of the second hook structure 16. At this time, the longitudinal arm of the second hook structure 16 provides support for the third hanging ear 512. After the bottom surface of the third hanging ear 512 is separated from the top surface of the longitudinal arm of the second hook structure 16, at the same time, since the second filter screen 52 is in a bent state due to the action of wind, the third hanging pin 511 is disengaged from the third hanging hole 15, so that the second sliding seat 51 slides downward until the bottom surface of the third hanging ear 512 contacts the top surface of the cross arm of the second hook structure 16, as Figure 13 shown. Thus, when the second filter screen 52 stops being affected by wind, the sixth spring 53 pushes the second sliding seat 51 to slide towards the air inlet 11 direction, as Figure 13As shown, since the third hanging ear 512 is blocked by the longitudinal arm of the second hook structure 16 at this time, the third hanging ear 512 disengages from the second sliding seat 51. At this time, the second torsion spring 71 drives the second winding roller 7 to wind up. The second winding roller 7 winds up the second filter net 52, causing the second filter net 52 to change from the unfolded state to the wound state, and driving the first filter net 23 to unwind against the torsion of the first torsion spring 41 through the traction assembly, so that the first filter net 23 changes from the wound state to the unfolded state, thereby realizing the switching between the first filter net 23 and the second filter net 52.

[0056] As Figures 1 to 4 shown, for the automotive air conditioner filter described in this embodiment, in some embodiments, the traction assembly includes a pulley seat 61 and a traction rope 62. The pulley seat 61 is fixedly provided on the housing 1. A fixed pulley 63 is rotatably provided on the pulley seat 61. The traction rope 62 is wound around the fixed pulley 63. The two ends of the traction rope 62 are respectively connected to the second sliding seat 51 and the first filter net 23. By providing a fulcrum through the fixed pulley 63 in this embodiment, the linkage between the first filter net 23 and the second filter net 52 is realized by using the traction rope 62, and the switching between the first filter net 23 and the second filter net 52 is realized.

[0057] As shown Figure 1 、 Figures 3 to 5 、 Figures 9 to 11 shown, for the automotive air conditioner filter described in this embodiment, in some embodiments, the other end of the first filter net 23 is provided with a first clamping plate 24, and a first power-on contact 241 is provided on the first clamping plate 24; both the first winding roller 4 and the second winding roller 7 are conductive rollers; a conductive sheet 8 is provided on the housing 1. The first power-on contact 241 electrically contacts the conductive sheet 8 after passing through the first sliding seat 21 when the first filter layer is in the unfolded state; the other end of the second filter net 52 is provided with a second clamping plate 54, and a second power-on contact 541 is provided on the second clamping plate 54. The second power-on contact 541 electrically contacts the conductive sheet 8 after passing through the second sliding seat 51 when the first filter layer is in the unfolded state.

[0058] Specifically, when the second filter net 52 is in the unfolded state, the second power-on contact 541 electrically contacts the conductive sheet 8, so that static electricity is applied to the second filter net 52 by using the second power-on contact 541 and the second winding roller 7, and the static electricity is released to the filter net surface, so that static ions adhere to the filter net surface, increasing the air filtration effect of the second filter net 52 and ensuring that the static adsorption effect of the second filter net 52 does not change with time;

[0059] When the second filter net 52 is in the wound state, since the second sliding seat 51 slides downward, the second power-on contact 541 is disengaged from the conductive sheet 8, thereby canceling the static adsorption of the second filter net 52 and preventing the second filter net 52 from still having static ions when not in use;

[0060] Similarly, when the first filter 23 is in the unfolded state, the first powered contact 241 is in electrical contact with the conductive sheet 8, so that static electricity is applied to the first filter 23 by utilizing the first powered contact 241 and the first winding roller 4, and the static electricity is released to the surface of the filter, so that the surface of the filter adheres to static ions, thereby increasing the filtering effect of the first filter 23 on the air, and ensuring that the electrostatic adsorption effect of the first filter 23 does not change with time.

[0061] like Figure 7 As shown, the automobile air conditioning filter described in this embodiment, in some embodiments, the first clamping plate 24 is provided with a clamping assembly, the clamping assembly includes a through hole 551, a third slide groove 552 symmetrically arranged on both sides of the through hole 551 and connected with the through hole 551, and a push pin 553 symmetrically arranged on both sides of the through hole 551, a clamping claw 554 is slidably provided in the third slide groove 552, a seventh spring 555 is connected between the clamping claw 554 and the third slide groove 552, the clamping claw 554 is slidably connected to the first clamping plate 24, the clamping claw 554 is provided with an inclined groove 556, one end of the push pin 553 abuts against the inclined groove 556, and the other end of the push pin 553 protrudes out of the first clamping plate 24; one end of the traction rope 62 is embedded in the through hole 551, and the two clamping claws 554 hold the traction rope 62 tightly under the elastic force of the seventh spring 555.

[0062] Specifically, when the second filter screen 52 is rolled up under the torsion force of the second torsion spring 71, the second filter screen layer drives the first filter screen 23 to overcome the torsion force of the first torsion spring 41 to unwind through the traction rope 62. As the first filter screen 23 moves upward, the first hanging ear 242 extends into the hanging groove 215, and the two hooks 2132 respectively overcome the elastic force of the fifth spring 2136 and slide toward the center until the second hanging ear and the hook 2132 are engaged with each other. As the first filter screen 23 continues to move upward, the first clamping plate 24 contacts the first sliding seat 21, and the first powered contact 241 is in electrical contact with the conductive sheet 8. At the same time, the push pin 553 is squeezed and pressed down by the first sliding seat 21. The push pin 553 cooperates with the inclined groove 556 to push the clamping claw 554 to overcome the elastic force of the seventh spring 555 and slide away from the traction rope 62, thereby releasing the traction rope 62 to facilitate the replacement of the second filter screen layer.

[0063] like Figure 2As shown in the figure, for the automotive air conditioner filter described in this embodiment, in some embodiments, a second receiving groove is provided on the side of the wind deflector 3 facing away from the air outlet 12. An eighth spring 34 is provided in the second receiving groove. One end of the latch 33 is slidably inserted into the second receiving groove and abuts against the eighth spring 34. By providing the eighth spring 34, the latch 33 is kept in a tendency to be inserted into the first sliding groove 13. When the ejector rod 32 presses the latch 33, the latch 33 compresses the eighth spring 34 and thus retracts into the second receiving groove and exits from the first sliding groove 13. At this time, the latch 33 releases the limit on the wind deflector 3, enabling the wind deflector 3 to slide downward under the elastic force of the first spring 31.

[0064] As Figure 8 shown in the figure, for the automotive air conditioner filter described in this embodiment, in some embodiments, third receiving grooves are provided at both ends of the first sliding seat 21.
