Description

Technical Field

[0001] The present invention relates to the technical field of vehicle lights, and specifically to an anti-aging vehicle light assembly. Background Art

[0002] As a core component of automotive safety and lighting functions, the dust removal, dehumidification, and sealing technology of vehicle lights is a key systematic project to delay the aging of vehicle lights and ensure optical performance and service life. Modern vehicle light designs target specific aging factors through a multi-layer protection structure. The external sealing layer uses a high-precision injection molding process to seamlessly combine a weather-resistant lamp cover with a base, supplemented by a silicone rubber seal ring and high and low temperature resistant rubber strips, effectively blocking the intrusion of external water vapor and dust, preventing yellowing, cracking of the lamp cover, and oxidation and corrosion of the metal reflective layer. The internal humidity control actively adsorbs residual moisture through a molecular sieve desiccant module (such as zeolite or silica gel), preventing deformation and embrittlement of plastic parts caused by moisture absorption expansion and the growth of mildew spots on optical lenses; the dust removal design forms a dynamic "eddy current barrier" on the surface of the lamp cavity through aerodynamic optimized multi-gradient diversion grooves and an electrostatic dust-removing coating, directing the export of dust particles, and combining with the multi-folded paths of the labyrinth seal structure at the joints to jointly block the light transmittance attenuation and surface wear and aging caused by long-term dust deposition.

[0003] In the existing vehicle light sealing technology, as the core component of humidity control, the desiccant module generally uses molecular sieve or silica gel materials encapsulated at specific positions inside the lamp cavity, and passively absorbs the water vapor penetrating into the lamp cavity through the physical adsorption principle. However, due to the limited moisture absorption capacity of the desiccant material, it is easy to reach the saturation threshold under long-term high humidity conditions of the vehicle (such as frequent use during the rainy season and intrusion of high-pressure water mist during car washing), resulting in a decay of the moisture absorption efficiency index. Secondly, the saturated desiccant module cannot be regenerated and needs to be manually disassembled and replaced. The operation process involves complex processes such as peeling off the lamp cover sealant and disconnecting the wiring harness, there is a risk of secondary damage to the sealing structure and the maintenance cost is high, and users often delay the operation due to unclear replacement cycles or weak maintenance awareness, resulting in a long-term high humidity state inside the lamp cavity, causing accelerated aging phenomena such as electrochemical corrosion of the metal reflective layer, hydrolysis and embrittlement of the plastic substrate, and expansion of microcracks on the surface of the optical lens. At the same time, water vapor condenses into fog under temperature alternating conditions, causing a decrease in light transmittance. Summary of the Invention

[0004] (I) Technical problems to be solved: Aiming at the deficiencies of the prior art, the present invention provides an anti-aging vehicle light assembly, which has the advantages of renewable circulation of the dehumidifying desiccant, and solves the problems of low moisture absorption capacity of the desiccant module in existing vehicle lights, frequent replacement, and high humidity affecting the aging of vehicle lights.

[0005] (2) Technical solution: To achieve the purpose of renewable cycle of the dehumidifying desiccant, the present invention provides the following technical solution: An anti-aging headlight assembly includes a fixed outer cylinder and a rotating inner cylinder. The fixed outer cylinder is fixedly installed on the sealing port of the headlight base. The rotating inner cylinder is coaxially and rotatably connected in the fixed outer cylinder. A rotating shaft is coaxially and fixedly installed in the rotating inner cylinder. The rotating shaft and the rotating inner cylinder are separated by a fixed partition into two independent adsorption chambers filled with adsorbent. Inner covers and outer covers are respectively fixedly installed at both ends of the fixed outer cylinder. Two axially slidable sliding partitions are provided on the rotating shaft. The length of the sliding partition is less than that of the rotating inner cylinder, and the two adsorption chambers are respectively divided into two communicating circulation chambers. A spiral convex rod with a spiral track is coaxially provided in the rotating shaft. The spiral convex rod is fixedly connected to the inner cover. A guiding key is fixed at the bottom of the sliding partition and passes through the rotating shaft and moves along the spiral track. The spiral track axially has an upper limit point and a lower limit point. When the rotating inner cylinder rotates, it drives the guiding key to rotate along the spiral track. When the guiding key is at the upper limit point or the lower limit point, the sliding partition respectively presses tightly against the inner cover or the outer cover, so that the gas needs to pass through the two circulation chambers before being discharged.

[0006] Preferably, two inner circulation holes communicating with the rotating inner cylinder are symmetrically opened on the left side of the vertical diameter of the inner cover. Two outer circulation holes communicating with the rotating inner cylinder are symmetrically opened on the right side of the vertical diameter of the outer cover. The inner circulation holes communicate with the inside of the headlight. One of the outer circulation holes is connected to an active heat dissipation module, and a one-way valve is fixedly assembled on the other outer circulation hole, and the gas flow direction of the one-way valve faces the external environment. The two sliding partitions are arranged at 180°. When one group of sliding partitions is at the upper limit point, the other group of sliding partitions is at the lower limit point. When the guiding key moves to the upper limit point, the sliding partition axially slides and presses tightly against the inner cover, so that the gas in the headlight enters the circulation chamber through one of the inner circulation holes, and flows along the gap between the sliding partition and the outer cover to the other circulation chamber, and finally returns to the headlight through the other inner circulation hole. When the guiding key moves to the lower limit point, the sliding partition axially slides and presses tightly against the outer cover, so that the gas in the active heat dissipation module enters the circulation chamber through one of the outer circulation holes, and flows along the gap between the sliding partition and the inner cover to the other circulation chamber, and finally is discharged through the other outer circulation hole.

[0007] Preferably, a swing sleeve is also coaxially and rotatably connected inside the rotating inner cylinder. One end of the fixed partition is fixedly connected to the swing sleeve, and the other end of the fixed partition is fixedly connected to the rotating shaft. A reset module for causing the swing sleeve to reciprocally swing relative to the rotating inner cylinder is further provided between the swing sleeve and the rotating inner cylinder. When the vehicle vibrates during driving, the swing sleeve is caused to reciprocally swing relative to the rotating inner cylinder; Axial flow fan blades with the same working surface direction are provided at both ends of the circulation cavity, and the working surfaces of the axial flow fan blades provided in adjacent circulation cavities are different. When the guiding key is at the upper limit point or the lower limit point, the sliding partition is in a horizontal state, and the limiting angle between the upper limit point and the lower limit point is greater than the swinging angle of the swing sleeve; When the guiding key is at the upper limit point, the wind direction generated by the working surface of the axial flow fan blade in the circulation cavity below the sliding partition is from the inner cover to the outer cover direction, and the wind direction generated by the working surface of the axial flow fan blade in the circulation cavity above the sliding partition is from the outer cover to the inner cover direction. During the swinging process of the swing sleeve, the axial flow fan blades cause gas flow in the circulation cavity.

[0008] Preferably, the axial flow fan blades are coaxially arranged with the rotating inner cylinder, and one end of the axial flow fan blades is fixedly connected to the swing sleeve, and the other end is fixedly connected to the rotating shaft.

[0009] Preferably, the distance between the axial flow fan blades at both ends of the circulation cavity is less than the length of the rotating inner cylinder.

[0010] Preferably, the reset module includes a swing key, a chute, and an elastic structure. Several groups of swing keys are fixedly arranged along the circumferential direction of the swing sleeve, several groups of chutes are arranged along the circumferential direction of the rotating inner cylinder, the swing keys are slidably connected to the chutes, and the elastic structure is arranged in the circumferential direction of the swing keys and the chutes.

[0011] Preferably, the rotating shaft penetrates through the outer cover and is connected to a driving motor, and the driving motor periodically drives the rotating shaft to rotate 180°.

[0012] Preferably, the sliding partition and the fixed partition are arranged at 90°, and both the sliding partition and the fixed partition are arranged radially along the rotating shaft.

[0013] Preferably, the active heat dissipation module is connected to the heat dissipation structure of the vehicle lamp, and the heat dissipated by the heat dissipation structure of the vehicle lamp is conducted to the outer circulation hole through gas, and an active fan is arranged in the active heat dissipation module.

[0014] Preferably, the width of the guiding key is equal to the width of the spiral track.

[0015] (3) Beneficial effects: Compared with the prior art, the present invention provides an anti-aging vehicle lamp assembly with the following beneficial effects: 1. For this anti-aging vehicle lamp assembly, through the combined use of the rotating inner cylinder structure and the spiral convex rod structure, the adsorption cavity is divided into two independent working units. With the 180° periodic rotation drive, the dynamic switching of the adsorption and regeneration functions is realized. When one side of the adsorption cavity completes the moisture absorption operation, high-temperature air flow is introduced through the active heat dissipation module for thermal desorption regeneration. At the same time, the other adsorption cavity immediately switches to the working state. Compared with the traditional single desiccant module, the adsorption efficiency is greatly improved, and there is no need to manually disassemble and replace the desiccant during the entire service life, solving the problem of high humidity aging inside the vehicle lamp caused by maintenance delay.

[0016] 2. For this anti-aging vehicle lamp assembly, through the combined use of the swinging sleeve structure and the axial flow fan blade structure, the vehicle driving vibration is converted into the swinging power of the axial flow fan blade. The axial flow fan blade with an asymmetric airfoil design generates a directional air flow during the swinging process, greatly increasing the gas treatment volume per unit time during the adsorption stage. Not only does it not require an additional power device, but also the system energy consumption is greatly reduced through the recycling of vibration energy, and an effective dehumidification cycle can be maintained.

[0017] 3. For this anti-aging vehicle lamp assembly, through the combined use of the adsorption cavity structure and the sliding partition structure, a natural heat convection system between the vehicle lamp cavity and the adsorption cavity is constructed. During the adsorption stage, the rising air flow formed by the exothermic reaction is utilized to generate a natural suction pressure, enabling the moisture inside the vehicle lamp to dehumidify through autonomous circulation. And during the regeneration stage, the heat of the heat dissipation structure connected to the active heat dissipation module drives the desorption reaction, which is more energy-efficient than the electric heating regeneration method. At the same time, it avoids the risk of thermal aging of plastic parts caused by local overheating. Description of the Drawings

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 - 10, an anti-aging headlight component, comprising a fixed outer cylinder 1 and a rotating inner cylinder 2. The fixed outer cylinder 1 is fixedly installed on the sealing opening of the headlight base, which can ensure the stability and sealing performance of the headlight component, prevent external dust, water vapor, etc. from entering the headlight interior, and extend the service life of the headlight. The rotating inner cylinder 2 is coaxially and rotatably connected in the fixed outer cylinder 1, thereby realizing the rotation function of the rotating inner cylinder 2, facilitating the switching and regeneration of the adsorption cavity 22. A rotating shaft 3 is coaxially and fixedly installed inside the rotating inner cylinder 2. The rotating shaft 3 and the rotating inner cylinder 2 are separated by a fixed partition 21 into two independent adsorption cavities 22 filled with adsorbents, realizing the independent operation of the adsorption cavity 22 and facilitating the switching between adsorption and regeneration. Inner covers 6 and outer covers 7 are respectively fixedly installed at both ends of the fixed outer cylinder 1. The inner covers 6 and outer covers 7 ensure the sealing performance of the adsorption cavity 22, prevent gas leakage, and improve the adsorption efficiency. Two axially slidable sliding partitions 5 are provided on the rotating shaft 3. The length of the sliding partition 5 is less than that of the rotating inner cylinder 2, and the two adsorption cavities 22 are respectively divided into two communicating circulation cavities 221 (as shown in Figure 10 ). Through the design of the sliding partition 5, the switching and regeneration of the adsorption cavity 22 are realized, facilitating the dynamic switching between adsorption and regeneration, and improving the adsorption efficiency and service life. A spiral convex rod 4 with a spiral track 41 is coaxially provided inside the rotating shaft 3 (as shown in Figure 8 and Figure 9 ). The spiral convex rod 4 is fixedly connected to the inner cover 6. The fixed connection between the spiral convex rod 4 and the inner cover 6 ensures the stability of the spiral convex rod 4 and facilitates the axial sliding of the sliding partition 5. A guiding key 51 is fixed at the bottom of the sliding partition 5, passing through the rotating shaft 3 and moving along the spiral track 41. Upper limit points 42 and lower limit points 43 are axially provided on the spiral track 41. When the rotating inner cylinder 2 rotates, it drives the guiding key 51 to rotate along the spiral track 41. When the guiding key 51 is at the upper limit point 42 or the lower limit point 43, the sliding partition 5 respectively presses against the inner cover 6 or the outer cover 7, so that the gas needs to pass through the two circulation cavities 221 before being discharged.

[0033] Please refer to Figures 1 - 10, two inner circulation holes 61 communicating with the rotating inner cylinder 2 are symmetrically opened on the left side of the vertical diameter of the inner cover 6, and two outer circulation holes 71 communicating with the rotating inner cylinder 2 are symmetrically opened on the right side of the vertical diameter of the outer cover 7. The inner circulation holes 61 are communicated with the inside of the vehicle lamp. One of the outer circulation holes 71 is connected with the active heat dissipation module 10, and a one-way valve (not shown) is fixedly assembled on the other outer circulation hole 71, and the gas flow direction of the one-way valve faces the external environment, so as to realize the adsorption of moisture inside the vehicle lamp and the regeneration cycle of the desiccant. The inner circulation hole 61 is connected with the inside of the vehicle lamp, allowing the moisture in the vehicle lamp to enter the adsorption cavity 22 for dehumidification; the outer circulation hole 71 is connected with the active heat dissipation module 10, allowing high-temperature gas to enter the adsorption cavity 22 to perform thermal desorption regeneration on the saturated desiccant. The two sets of sliding partitions 5 are arranged at 180°. When one set of sliding partitions 5 is at the upper limit point 42, the other set of sliding partitions 5 is at the lower limit point 43. When one set of sliding partitions 5 is at the upper limit point 42, the corresponding adsorption cavity 22 is communicated with the inside of the vehicle lamp for dehumidification; at the same time, the other set of sliding partitions 5 is at the lower limit point 43, and the corresponding adsorption cavity 22 is communicated with the active heat dissipation module 10 for regeneration. The 180° setting can ensure that the two adsorption cavities 22 work alternately, ensuring that at least one adsorption cavity 22 is always in a working state. Please refer to Figure 12(The arrow direction is the air flow direction). When the guiding key 51 moves to the upper limit point 42, the sliding partition 5 slides axially and presses against the inner cover 6, enabling the gas inside the vehicle lamp to enter the circulation cavity 221 through an inner circulation hole 61, and flow along the gap between the sliding partition 5 and the outer cover 7 to another circulation cavity 221, and finally return to the vehicle lamp through another inner circulation hole 61; when the guiding key 51 moves to the lower limit point 43, the sliding partition 5 slides axially and presses against the outer cover 7, enabling the gas inside the active heat dissipation module 10 to enter the circulation cavity 221 through an outer circulation hole 71, and flow along the gap between the sliding partition 5 and the inner cover 6 to another circulation cavity 221, and finally be discharged through another outer circulation hole 71. The active heat dissipation module 10 is connected to the heat dissipation structure of the vehicle lamp and conducts the heat dissipated by the heat dissipation structure of the vehicle lamp to the outer circulation hole 71 through gas. An active fan is provided inside the active heat dissipation module 10. The active heat dissipation module 10 is connected to the heat dissipation structure of the vehicle lamp and can obtain the waste heat of the vehicle lamp. The function of the active fan is to convert heat into gas flow, accelerating the heat conduction and the regeneration process of the desiccant. Among them, the heat dissipation structure of the vehicle lamp includes a radiator, heat sinks, etc., and these components are connected to the heat-generating components of the vehicle lamp. By connecting to these heat dissipation structures, the active heat dissipation module 10 can effectively obtain and utilize this waste heat. The rotating shaft 3 passes through the outer cover 7 and is connected to a driving motor 11, and the driving motor 11 periodically drives the rotating shaft 3 to rotate 180°. The driving motor 11 periodically drives the rotating shaft 3 to rotate 180°, driving the guiding key 51 to move along the spiral track 41, so that the sliding partition 5 switches between the upper limit point 42 and the lower limit point 43. And it can ensure that the adsorption cavity 22 alternately dehumidifies and regenerates, improving the adsorption efficiency and service life. The sliding partition 5 and the fixed partition 21 are arranged at 90°, and both the sliding partition 5 and the fixed partition 21 are arranged radially along the rotating shaft 3. The 90° setting can ensure that the sliding partition 5 can smoothly press against the inner cover 6 or the outer cover 7 during the sliding process, closing the corresponding passage. The width of the guiding key 51 is equal to the width of the spiral track 41. The width of the guiding key 51 being equal to the width of the spiral track 41 can prevent the guiding key 51 from shaking or shifting during the sliding process, ensuring the accurate positioning and stable sliding of the sliding partition 5.

[0034] Please refer to Figure 5 、 Figure 6 、 Figure 7 and Figure 11, a swing sleeve 8 is also coaxially and rotatably connected inside the rotating inner cylinder 2. One end of the fixed partition 21 is fixedly connected to the swing sleeve 8, and the other end of the fixed partition 21 is fixedly connected to the rotating shaft 3. A reset module 81 is also provided between the swing sleeve 8 and the rotating inner cylinder 2 to cause the swing sleeve 8 to reciprocally swing relative to the rotating inner cylinder 2. When the vehicle vibrates during driving, the swing sleeve 8 is caused to reciprocally swing relative to the rotating inner cylinder 2. The reset module 81 enables the swing sleeve 8 to reciprocally swing relative to the rotating inner cylinder 2 when the vehicle vibrates, without additional energy input. This design not only improves the energy utilization efficiency but also enhances the gas flow inside the assembly through swinging, contributing to improving the dehumidification and regeneration efficiency. Axial flow fan blades 9 with the same working surface direction are provided at both ends of the circulation cavity 221 (as shown in Figure 5 and Figure 7 ), and the working surfaces of the axial flow fan blades 9 provided in adjacent circulation cavities 221 are different. The axial flow fan blades 9 with the same working surface direction can generate a consistent air flow direction during the swinging process, while the different settings of the working surfaces of the axial flow fan blades 9 in adjacent circulation cavities 221 ensure the effective flow of air in the circulation cavity 221. When the guiding key 51 is at the upper limit point 42 or the lower limit point 43, the sliding partition 5 is in a horizontal state, and the limiting angle between the upper limit point 42 and the lower limit point 43 is greater than the swinging angle of the swing sleeve 8, ensuring that the sliding partition 5 is not affected during the swinging process of the swing sleeve 8, thereby maintaining a stable closed state. When the guiding key 51 is at the upper limit point 42, the air flow direction generated by the working surface of the axial flow fan blade 9 in the circulation cavity 221 below the sliding partition 5 is from the inner cover 6 to the outer cover 7, and the air flow direction generated by the working surface of the axial flow fan blade 9 in the circulation cavity 221 above the sliding partition 5 is from the outer cover 7 to the inner cover 6. During the swinging process of the swing sleeve 8, the axial flow fan blade 9 causes gas flow in the circulation cavity 221.

[0035] Please refer to Figure 5 , Figure 6 , Figure 7 and Figure 11 . The axial flow fan blade 9 is coaxially arranged with the rotating inner cylinder 2 to ensure that the swinging trajectory of the fan blade coincides with the axis of the inner cylinder. When the swing sleeve 8 deflects by a small angle due to vibration, the coaxial structure can avoid mechanical interference between the fan blade and the inner wall of the adsorption cavity 22, and at the same time ensure that the working surface of the fan blade is always perpendicular to the air flow direction, maximizing the aerodynamic efficiency. One end of the axial flow fan blade 9 is fixedly connected to the swing sleeve 8, and the other end is fixedly connected to the rotating shaft 3, forming a double - fulcrum support structure. This design directly converts the vibration energy of the swing sleeve 8 into the swinging kinetic energy of the axial flow fan blade 9 through a rigid connection. Compared with the single - point fixed structure, the energy transfer efficiency is effectively improved. The distance between the axial flow fan blades 9 at both ends of the circulation cavity 221 is less than the length of the rotating inner cylinder 2, so that the circulation cavity 221 can be filled with sufficient adsorbent. Please refer to Figure 11, the reset module 81 includes a swing key 811, a chute 812, and an elastic structure 813. A plurality of groups of swing keys 811 are fixedly arranged along the circumferential direction of the swing sleeve 8, and a plurality of groups of chutes 812 are arranged along the circumferential direction of the rotating inner cylinder 2. The swing key 811 is slidably connected to the chute 812, and an elastic structure 813 is arranged in the circumferential direction of the swing key 811 and the chute 812. The elastic structure 813 is composed of a disc spring group, and the disc spring group is made of a temperature-resistant titanium-nickel memory alloy spring sheet. When the vehicle is subjected to an instantaneous impact, the swing key 811 compresses the spring to generate displacement and resets after the vibration ends, realizing the continuous conversion of vibration energy into air flow kinetic energy.

[0036] Working principle: A renewable adsorbent needs to be arranged in the adsorption chamber 22. During installation, one side of the adsorption chamber 22 is connected to the inside of the vehicle lamp through the inner circulation hole 61, and the outer circulation hole 71 on the other side is connected to the active heat dissipation module 10 of the vehicle lamp. The fixed outer cylinder 1 is fixed on the base seal of the vehicle lamp.

[0037] During the dehumidification process, the drive motor 11 drives the rotating shaft to rotate 180°, so that the guiding key 51 rotates along the spiral track 41 to the upper limit point 42. At this time, one side of the sliding partition 5 axially abuts against the inner cover 6, closing the passage between the adsorption chamber 22 and the inner cover 6, and forcing the air flow to circulate through the gap between the outer cover 7 and the sliding partition 5 near the inner side of the adsorption chamber 22. When the gas in the vehicle lamp cavity enters the adsorption chamber 22 through the inner circulation hole 61, since the gas is an exothermic reaction during the adsorption dehumidification process, its temperature will rise when the gas passes through the adsorbent, so that an upward air flow is formed when the gas passes through the adsorbent, creating a low-pressure area in the lower circulation chamber 221 below, generating a natural suction force from the lower inner circulation hole 61 to the upper inner circulation hole 61, and forming a natural gas flow in the vehicle lamp cavity and the adsorption chamber 22 from the vehicle lamp cavity - lower inner circulation hole 61 - lower circulation chamber 221 - gap between the sliding partition 5 and the outer cover 7 - upper circulation chamber 221 - upper circulation hole, so that the gas containing water vapor in the vehicle lamp can form natural heat convection and be absorbed by the adsorbent in the adsorption chamber 22 without the need for an additional gas active circulation structure, effectively reducing the humidity in the vehicle lamp.

[0038] During the regeneration process, the guiding key 51 rotates along the spiral track 41 to the lower limit point 43. At this time, one side of the sliding partition 5 is axially pressed against the outer cover 7, closing the passage between the adsorption cavity 22 and the outer cover 7, and forcing the air flow to circulate through the gap between the inner cover 6 and the sliding partition 5 near the inner side of the adsorption cavity 22. At the same time, the active heat dissipation module 10 is started (the active heat dissipation module 10 is installed on the lower outer circulation hole 71, and the upper outer circulation hole 71 is connected to the external environment), and the waste heat of the headlight radiator is introduced into the adsorption cavity 22 through the lower outer circulation hole 71, forming a flow path of the active heat dissipation module 10 - the lower outer circulation hole 71 - the lower circulation cavity 221 - the gap between the sliding partition 5 and the inner cover 6 - the upper circulation cavity 221 - the upper outer circulation hole 71 - the external environment. When the high-temperature gas flows through the adsorbent, the adsorbed water is released through thermal desorption, restoring the activity of the adsorbent, and the desorbed water vapor is discharged from the upper outer circulation hole 71 with the air flow, realizing the regeneration link of the adsorbent.

[0039] Among them, when the adsorbent is saturated, the drive motor 11 drives the rotating shaft to rotate 180°, so that the adsorption cavity 22 originally connected to the inner circulation hole 61 rotates to the other side to be connected to the outer circulation hole 71 for regeneration, and the adsorption cavity 22 originally connected to the outer circulation hole 71 is now connected to the inner circulation hole 61 for adsorption and dehumidification. Thus, the cycle of adsorption and regeneration is realized. Every time the motor drives the rotating shaft 3 to rotate half a week, the functions of the two adsorption cavities 22 are interchanged, ensuring that at least one adsorption cavity 22 is always in the working state, greatly improving the utilization efficiency of the adsorbent, making it unnecessary for manual maintenance during the life cycle of the headlight, and solving the problem of aging of the headlight affected by moisture due to the saturation and failure of the desiccant.

[0040] During the vehicle's driving process, vibrations are generated and transmitted to the swinging inner cylinder, causing it to rotate reciprocally relative to the rotating inner cylinder 2. Specifically, when the swinging inner cylinder swings, the swinging key 811 will rotate circumferentially within the slider, and the elastic structure 813 between the swinging key 811 and the sliding groove 812 will cause it to reset after rotation, generating periodic rotation and thus forming a swing. This swing causes the axial flow fan blade 9 to swing and rotate reciprocally. Specifically, during the adsorption process, when the axial flow fan within the adsorption chamber 22 connected to the inner circulation hole 61 swings, the axial flow fan blade 9 (with the working surface facing the outer cover 7) within the lower circulation chamber 221 will generate a wind direction towards the outer cover 7 side during the swing process, thereby accelerating the inhalation rate of the gas inside the headlight inner panel. And the axial flow fan blade 9 (with the working surface facing the inner cover 6) within the upper circulation chamber 221 will generate a wind direction towards the inner cover 6 side during the swing process, thereby enhancing the reflux rate of the gas, greatly increasing the gas treatment volume within the adsorption chamber 22 per unit time. During the regeneration process, when the gas enters the circulation chamber 221 through the axial flow fan blade 9 from the outer circulation hole 71, a certain eddy current effect will be generated, prolonging the residence time of the high-temperature gas in the adsorbent layer and improving the desorption efficiency. Among them, the directional air guiding function is achieved through its special structural design. It adopts an asymmetric airfoil design. The working surface (positive side) of the axial flow fan blade 9 has a larger inclination angle, while the inclination angle of the leeward surface (reverse side) is significantly reduced, forming an obvious difference in aerodynamic characteristics. When the axial flow fan blade 9 swings along the working surface direction, the inclination angle of the axial flow fan blade 9 can effectively capture the airflow and generate a strong directional flow; when the axial flow fan blade 9 swings in the reverse direction, the inclination angle turns into an unfavorable aerodynamic state, causing the airflow to separate and form turbulence, greatly suppressing the reverse flow.
