Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp dehumidification, in particular to a dehumidification device for a luminous vehicle lamp. Background Art

[0002] Headlights refer to the high and low beam lights installed on both sides of the front of the vehicle. Fogging means that when the lamp beads are working and generating heat, the moist air inside the headlights condenses on the inner surface of the transparent lampshade due to the heat to form small water droplets. The fogging phenomenon not only affects the lighting of the headlights, but is also very unsightly. In order to prevent the headlights from fogging, dehumidification devices are now often used to complete the dehumidification work inside the headlights. In actual use, they have the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses a dehumidification device for a headlight with announcement number CN221258636U. In the above-mentioned utility model, when replacing the desiccant, the dehumidification operation needs to be stopped before the desiccant can be replaced. This method affects the dehumidification operation inside the headlight and reduces the practicality of the utility model. At the same time, the fan provides power for the circulation of the gas. When the fan is damaged, the gas stops circulating and there is no prompt structure. The operator cannot know whether the gas continues to circulate, which brings hidden dangers to the continued use of the utility model.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a dehumidification device for luminous vehicle lamps, which has the following beneficial effects:

[0017] (1) The utility model adopts the installation of square tubes. Before the dehumidification device of the luminous lamp is actually used, one end of the external threaded tube and one end of the connecting tube can be inserted into the interior of the lamp. The fan and the forward and reverse motor can be operated by using the control panel. The output end of the forward and reverse motor can make the two sets of connecting shafts rotate in the same direction through four sets of pulleys and two sets of transmission belts.

When the desiccant needs to be cleaned, the control panel is used to make the forward and reverse motor work. The desiccant between the multiple groups of pistons can be gradually moved out of the interior of the installation square tube. At the same time, the newly placed desiccant can continue to perform dehumidification work. Through the installation square tube, the desiccant can be replaced without stopping the dehumidification work, thereby improving the practicality of the dehumidification device of the luminous headlight.

[0018] (2) The utility model adopts an installation box. According to the above operation, when the fan is working, the gas inside the shell can be drawn into the installation box through the air guide scoop. This part of the flowing gas can blow up the lifting plate. At this time, the operator can press the power switch. When the fan is damaged, the flowing gas cannot be formed. The lifting plate loses the push of the flowing gas and can move down along the two sets of T-shaped rods under the action of gravity. When the lifting plate that moves down presses the push switch, the buzzer alarm starts to work. The operator can know whether the fan is damaged by the sound of the buzzer alarm, and then know whether the gas is continuously circulating. The installation box is provided with a prompt structure, which can help the operator know whether the gas is continuously circulating, thereby ensuring the continuous use of the dehumidification device of the light-emitting lamp.

By setting the mounting square tube 8, the desiccant can be replaced without stopping the dehumidification work, thereby improving the practicality of the dehumidification device of the luminous headlights.

[0030] In one embodiment, two groups of T-shaped rods 21 are installed on the inner bottom surface of the installation box 6, and the side walls of the two groups of T-shaped rods 21 are slidably sleeved with lifting plates 22. A buzzer alarm 23 is fixedly penetrated through the inner bottom surface of the installation box 6, and a press switch 24 is installed on the upper part of the buzzer alarm 23. An electric control box 25 is installed on the outer wall of the installation box 6, and a battery and a power switch are installed inside the electric control box 25. The installation box 6 is provided with a prompt structure, which can help the operator know whether the gas is continuously circulating, thereby ensuring the continuous use of the dehumidification device of the light-emitting lamp.

[0031] In one embodiment, the push switch 24 and the power switch are electrically connected to the battery and the buzzer alarm 23 through wires, and the battery provides power to the buzzer alarm 23 .

[0032] In one embodiment, sealing plugs 13 are inserted into the interiors of the two groups of through holes 12 .

[0033] In one embodiment, a control panel is installed on the outer wall of the casing 1, and the control panel is electrically connected to the fan 2 and the forward and reverse motors through wires. The control circuit of the control panel can be implemented through simple programming by technicians in this field. It is common knowledge in this field and is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0034] In one embodiment, the threads of the internally threaded tube 3 and the externally threaded tube 4 cooperate with each other, making it easy to disassemble and assemble the internally threaded tube 3.

[0035] Working principle:

[0036] Before actually using the dehumidification device for the luminous lamp, one end of the external threaded tube 4 and one end of the connecting tube 7 can be inserted into the interior of the lamp, and the control panel can be used to operate the fan 2 and the forward and reverse motors. The output ends of the forward and reverse motors can make the two connecting shafts 15 rotate in the same direction through four sets of pulleys 19 and two sets of transmission belts 20. During this process, the two sets of reel drums 16 rotating in the same direction can pull the multiple sets of pistons 10 to the left or right through two sets of pull ropes 17. When the gap between the two adjacent sets of pistons 10 is below a set of through holes 12, desiccant can be placed through this set of through holes 12. When this part of the desiccant moves between the two sets of filters 9, the fan 2 can draw the gas inside the lamp through the external threaded tube 4 into the interior of the housing 1. The gas inside the housing 1 can pass through the two sets of filters 9 and the desiccant, and the gas then flows back to the lamp through the air guide 5, the installation box 6 and the connecting tube 7. When it is necessary to clean the desiccant, the control panel can be used to operate the forward and reverse motors, and the desiccant between the multiple sets of pistons 10 can be gradually moved out of the installation direction. Inside the tube 8, at the same time, the newly placed desiccant can continue to perform the dehumidification work. By setting the installation square tube 8, the desiccant can be replaced without stopping the dehumidification work, which improves the practicality of the dehumidification device of the luminous headlights. At the same time, according to the above operation, when the fan 2 is working, the gas inside the shell 1 can be drawn into the installation box 6 through the air guide 5. This part of the flowing gas can blow up the lifting plate 22. At this time, the operator can press the power switch. When the fan 2 is damaged, the flowing gas cannot be formed. The lifting plate 22 loses the push of the flowing gas and can move down along the two sets of T-shaped rods 21 under the action of gravity. When the downward-moving lifting plate 22 presses the press switch 24, the buzzer alarm 23 starts to work. The operator can know whether the fan 2 is damaged by the sound emitted by the buzzer alarm 23, and then know whether the gas continues to circulate. The installation box 6 is provided with a prompt structure, which can help the operator know whether the gas continues to circulate, thereby ensuring the continuous use of the dehumidification device of the luminous headlights.
