The desiccant recycling device for anti-fog vehicle lamps according to claim 1, characterized in that: The sensing unit includes any one or more combinations of temperature sensors, humidity sensors, pressure sensors, and infrared sensors; the sensing unit is deployed at the air intake structure of the lamp housing, at the corner of the lamp housing, or in any one or more combinations of the desiccant storage unit.

5. The desiccant recycling device for anti-fog vehicle lamps according to claim 3, characterized in that: The sensing unit has a circuit structure or a wireless communication module for communicating with the desiccant replacement controller, and is used to send humidity change information in the lamp and status information of the desiccant in the desiccant storage unit to the desiccant replacement controller; the desiccant status information includes any one or more combinations of desiccant water absorption status information, desiccant fluffiness information, and desiccant compaction information.

6. The desiccant recycling device for anti-fog vehicle lamps according to claim 5, characterized in that: The method of generating an instruction to control the desiccant storage unit to be removed according to the humidity change information in the lamp and the state information of the desiccant comprises the following steps: Calculating a desiccant effectiveness indicator value based on a total amount of change in the humidity in the lamp cavity within a preset time period and / or a maximum amount of change in the humidity in the lamp cavity within a preset time period and / or a difference between multiple amounts of change in the humidity in the lamp cavity within a preset time period; Calculate the desiccant performance evaluation value based on the water absorption state of the desiccant and / or the fluffiness of the desiccant and / or the compaction state of the desiccant; Calculating a desiccant replacement indication value based on a desiccant utility indication value and / or a desiccant performance evaluation value; When the desiccant replacement indication value is greater than a preset desiccant replacement threshold, an instruction for controlling the desiccant storage unit to be removed is generated.

7. The desiccant recycling device for anti-fog vehicle lamps according to claim 1, characterized in that: The recovery chamber includes a storage structure and a recovery structure; the storage structure has a cavity for receiving the desiccant storage unit that has fallen out of the lamp housing, and the recovery structure adopts any one of an automatic dehumidification structure and / or a manual replacement structure. The automatic dehumidification structure dehumidifies the desiccant to restore some of its performance, and the manual replacement structure manually takes out and replaces the desiccant and then puts it into the desiccant storage unit.

8. The desiccant recycling device for anti-fog vehicle lamps according to claim 1, characterized in that: The transfer component adopts any one or more combinations of a hinge structure, a slide rail structure or a traction rope structure. When the recovery program of the recovery structure is completed, the transfer component starts to push the desiccant storage unit in the to-be-recovered bin into the recovered bin.

9. The desiccant recycling device for anti-fog vehicle lamps according to claim 1, characterized in that: The restored warehouse adopts a double-bin structure, one bin stores the restored desiccant storage unit, and the other bin is empty for receiving the next restored desiccant storage unit; the restored warehouse also includes a push control structure, which receives the control instruction of the desiccant replacement controller and pushes the restored desiccant storage unit in the double-bin structure into the original position of the desiccant replacement unit.

10. A desiccant replacement control system, characterized in that: include: Desiccant replacement controller; Memory; as well as One or more programs, wherein the one or more programs are stored in a memory and are configured to cause the desiccant replacement controller to execute the step of generating an instruction to control the desiccant storage unit to be removed based on the humidity change information in the lamp and the status information of the desiccant as described in claim 6.
