Description

Technical Field

[0001] This utility model relates to the field of dehumidification device technology, and in particular to a multi-channel dehumidifier, vehicle lights, and vehicles. Background Technology

[0002] To address the issue of moisture seeping into the sealed space of vehicle lights and indoor / outdoor lighting equipment, forming water vapor, existing technologies utilize efficient adsorption technology to achieve anti-fogging and dehumidification functions. This effectively prevents fogging on the lamp cover surface and quickly eliminates existing fog, thereby improving driving safety. However, current condensation controller designs have limited storage space for the desiccant, restricting its moisture absorption effect. Furthermore, once the desiccant is loaded, the limited storage space can cause it to saturate and overflow the condensation controller, posing a risk of rupturing it. Utility Model Content

The support frame is engaged inside the receiving cavity, and the intake soft rubber valve and the exhaust soft rubber valve are engaged on the support frame.

[0008] Preferably, the multi-channel dehumidifier also includes a sealing ring, a boss is provided on the circumferential outer surface of the housing, the sealing ring is fitted on the housing, and the sealing ring abuts against the side of the boss near the connection end.

[0009] Preferably, the boss is provided with a locking part and a gripping part on both sides near the connecting end and the working end, respectively.

[0010] Preferably, the snap-fit ​​portion includes a plurality of snap-fit ​​blocks arranged in annular intervals. Each snap-fit ​​block includes a first block and a second block, with the second block facing the connection end and perpendicular to the first block.

[0011] This utility model also provides a vehicle light, which includes a light box and a multi-channel dehumidifier. The multi-channel dehumidifier is connected to the light box, and the connection end of the multi-channel dehumidifier is at least partially located inside the light box, while the working end of the multi-channel dehumidifier is located outside the light box.

[0012] This utility model also provides a vehicle, which includes a vehicle body, headlights, and a multi-channel dehumidifier. The multi-channel dehumidifier is mounted on the headlights, which are connected to the vehicle body.

[0013] Compared with the prior art, the multi-channel dehumidifier, vehicle light, and vehicle provided by this utility model have the following beneficial effects: 1. The multi-channel dehumidifier provided in this embodiment of the utility model is designed to dehumidify and prevent fogging of vehicle lights or other indoor and outdoor lighting facilities. In use, the multi-channel dehumidifier is connected to the vehicle light. The housing of the multi-channel dehumidifier has a connecting channel extending through both ends of the housing. The connecting channel includes a connecting end and a working end located at each end of the housing. The side of the housing near the connecting end of the connecting channel is placed inside the vehicle light, while the side near the working end of the connecting channel is placed in the external environment. By placing the dehumidifying element within the connecting channel, moisture inside the vehicle light enters the connecting channel through the opening at the connecting end and is absorbed by the dehumidifying element, thereby achieving dehumidification and fogging of the interior space of the vehicle light. Furthermore, the housing has a ventilation channel independent of the connecting channel. When the gas inside the vehicle light expands and contracts due to heat, the vehicle light and the outside environment exchange gases through the independent ventilation channel, avoiding a pressure difference between the inside and outside of the vehicle light that could damage it. Simultaneously, because at least a portion of the ventilation channel is inserted into the positioning groove, the structure of the multi-channel dehumidifier is more stable and easier to install. The multi-channel desiccant has independent connecting channels and ventilation channels inside the housing, which are used for moisture absorption and ventilation respectively. This ensures that the vehicle headlights can maintain stable ventilation while ensuring that the desiccant can be placed in the connecting channels with sufficient space. This avoids the risk of the desiccant bursting after saturation and improves the structural stability of the multi-channel desiccant.

[0014] 2. In this embodiment of the invention, a first waterproof and breathable membrane is provided on the connecting end. The first waterproof and breathable membrane seals the connecting end, and the opening of the breathable channel near the connecting end is spaced apart from the first waterproof and breathable membrane. Based on the waterproof and breathable properties of the first waterproof and breathable membrane, moisture inside the vehicle headlight can pass through the first waterproof and breathable membrane into the connecting channel, while preventing moisture or desiccant from entering the vehicle headlight. Furthermore, the spaced arrangement between the opening of the breathable channel and the opening of the connecting end separates the first waterproof and breathable membrane sealing the connecting end from the breathable channel, reducing the number of sealing points required for the first waterproof and breathable membrane and further reducing the risk of desiccant leakage after sealing.

[0015] 3. In this embodiment of the utility model, the connecting channel includes a first cavity and a second cavity connected together. The diameter of the first cavity is larger than the diameter of the second cavity. The working end and the connecting end are located in the first cavity and the second cavity respectively, and the diameter of the working end is larger than the diameter of the connecting end. Since the connecting end needs to be inserted into and connected to the vehicle light, the size design of the connecting end is limited. By setting the diameter of the working end to be larger than the diameter of the connecting end, and the diameter of the first cavity corresponding to the working end and the connecting end is also larger than the diameter of the second cavity, the space of the connecting channel inside the housing is further increased without affecting the sealing and stability effect of the multi-channel desiccant connected to the vehicle light, thus avoiding the risk of the desiccant breaking the multi-channel desiccant.

[0016] 4. In this embodiment of the invention, a receiving cavity is provided on the breathing cover, and a positioning groove connects to the receiving cavity. The opening of the receiving cavity is set as a vent. A second waterproof and breathable membrane is provided inside the receiving cavity, and the second waterproof and breathable membrane seals the vent. The second waterproof and breathable membrane can ensure gas flow while preventing external moisture or other impurities from entering the multi-channel dehumidifier, further improving the moisture-proof performance and stability of the multi-channel dehumidifier. At the same time, the second waterproof and breathable membrane can also play a certain role in dust prevention, extending the service life of the multi-channel dehumidifier. The second waterproof and breathable membrane is set inside the receiving cavity, which facilitates its installation and fixation.

[0017] 5. In this embodiment of the invention, a valve body assembly is provided within the receiving cavity. The valve body assembly includes a support frame, an inlet soft rubber valve, and an exhaust soft rubber valve. The support frame is engaged within the receiving cavity, and the inlet and exhaust soft rubber valves are engaged with the support frame. The valve body assembly enables control of the opening and closing of the ventilation channel, allowing stable exchange of gas inside the headlight with the outside environment, preventing pressure differences between the inside and outside of the headlight from damaging it. Simultaneously, the independent intake / exhaust of the inlet and exhaust soft rubber valves makes it more difficult for external moisture to enter the headlight, while facilitating the expulsion of gas from inside the headlight.

[0018] 6. In this embodiment of the utility model, the multi-channel dehumidifier further includes a sealing ring. A boss is provided on the circumferential outer surface of the housing, and the sealing ring is fitted onto the housing, with the sealing ring abutting against the side of the boss near the connecting end. The sealing ring further improves the sealing performance of the multi-channel dehumidifier, preventing external moisture or other impurities from entering the interior of the headlight, thus further ensuring the moisture-proof performance and stability of the multi-channel dehumidifier. Simultaneously, the sealing ring also acts as a shock absorber and buffer, protecting the multi-channel dehumidifier from impacts and damage from the external environment, and extending its service life.

[0019] 7. In this embodiment of the utility model, the boss is provided with a snap-fit ​​part and a gripping part on both sides near the connecting end and the working end, respectively. The snap-fit ​​part makes it easy to snap the multi-channel dehumidifier onto the vehicle headlight or other lighting equipment, improving the connection stability of the multi-channel dehumidifier. The gripping part makes it easy for the user to grasp the multi-port dehumidifier, thereby making it easier to rotate, adjust or disassemble the multi-port dehumidifier.

[0020] 8. In this embodiment of the utility model, the snap-fit ​​part includes a plurality of snap-fit ​​blocks arranged in annular intervals. Each snap-fit ​​block includes a first block and a second block. The second block faces the connection end and is perpendicular to the first block, which improves the snap-fit ​​fixing effect of the multi-channel dehumidifier on the vehicle light, further ensuring the stability and reliability of the connection between the multi-channel dehumidifier and the vehicle light, making it easier for users to install and disassemble, and improving the convenience of use.

[0021] 9. This utility model also provides a vehicle lamp, which includes a lamp housing and a multi-channel dehumidifier. The multi-channel dehumidifier is connected to the lamp housing, and at least part of the connection end of the multi-channel dehumidifier is located inside the lamp housing, while the working end of the multi-channel dehumidifier is located outside the lamp housing. The vehicle lamp has the same beneficial effects as the aforementioned multi-channel dehumidifier, and will not be described in detail here.

[0022] 10. This utility model also provides a vehicle, which includes a vehicle body, headlights, and a multi-channel dehumidifier. The multi-channel dehumidifier is mounted on the headlights, which are connected to the vehicle body. The vehicle has the same beneficial effects as the aforementioned multi-channel dehumidifier, and will not be described in detail here. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0037] To address the issue of moisture seeping into the sealed space of vehicle lights and indoor / outdoor lighting equipment, forming water vapor, existing technologies utilize efficient adsorption technology to achieve anti-fogging and dehumidification functions. This effectively prevents fogging on the lamp cover surface and quickly eliminates existing fog, thereby improving driving safety. However, current condensation controller designs have limited storage space for the desiccant, restricting its moisture absorption effect. Furthermore, once the desiccant is loaded, the limited storage space can cause it to saturate and overflow the condensation controller, posing a risk of rupturing it.

[0038] To address the structural instability of existing condensation controllers, please refer to [the relevant documentation / reference]. Figures 1-4The first embodiment of this utility model provides a multi-channel dehumidifier 1. The multi-channel dehumidifier 1 includes a housing 11, a dehumidifying element 13, and a breathing cover 12. The housing 11 is provided with a connecting channel 111 that passes through both ends of the housing 11. The dehumidifying element 13 is disposed in the connecting channel 111. The connecting channel 111 includes a connecting end 1111 and a working end 1112 located at both ends of the housing 11. The breathing cover 12 is connected to the housing 11 and closes the working end 1112. The breathing cover 12 is provided with a vent 123 and a positioning groove 121 communicating with the vent 123. The housing 11 is provided with a vent 112 that is independent of the connecting channel 111. At least part of the side of the vent 112 near the working end 1112 is placed in the connecting channel 111 and inserted into the positioning groove 121. The breathing cover 12 closes the vent 112. The end of the vent 112 near the connecting end 1111 passes through the housing 11, and the opening of the vent 112 is spaced apart from the opening of the connecting end 1111.

[0039] It should be noted that in daily life, when a light fixture is turned on, the gas inside the lampshade expands due to heat. After the light is turned off, the temperature drops rapidly, the air contracts, and a pressure difference is created inside and outside the lampshade. At the same time, since the light fixture itself is not completely sealed, a complete seal would cause it to burst due to the large pressure difference generated by temperature changes. This makes it easy for the light fixture to draw in humid air from outside. When the humid air cools on the cold inner wall of the lampshade and the humidity reaches saturation, it will condense into water droplets, thus affecting the normal use of the light fixture.

[0040] The multi-channel dehumidifier 1 provided in the first embodiment of this utility model is intended to dehumidify and prevent fogging of lamps or other indoor and outdoor lighting facilities. As one implementation method, the multi-channel dehumidifier 1 is connected to the lamp. The housing 11 of the multi-channel dehumidifier 1 is provided with a connecting channel 111 that runs through both ends of the housing 11. The connecting channel 111 includes a connecting end 1111 and a working end 1112 located at both ends of the housing 11. The side of the housing 11 near the connecting end 1111 of the connecting channel 111 is placed inside the lamp, and the side of the housing 11 near the working end 1112 of the connecting channel 111 is placed in the external environment. By placing the dehumidifying element 13 in the connecting channel 111, the moisture inside the lamp enters the connecting channel 111 through the opening of the connecting end 1111 and is absorbed by the dehumidifying element 13, thereby achieving dehumidification and fogging of the internal space of the lamp. Furthermore, the housing 11 is provided with a ventilation channel 112 independent of the connecting channel 111. The ventilation channel 112 is located on the inner wall of the connecting channel 111, and the ventilation channel 112 and the connecting channel 111 are arranged parallel to each other. When the gas inside the lamp expands and contracts due to heating, the lamp and the outside world exchange gases through the independent ventilation channel 112, avoiding the formation of a pressure difference between the inside and outside of the lamp that could damage the lamp. At the same time, since at least a portion of the ventilation channel 112 is inserted into the positioning groove 121, the structure of the multi-channel desiccant 1 is more stable and easier to install. By providing independent connecting channels 111 and ventilation channels 112 within the housing 11, which are used for moisture absorption and ventilation respectively, the multi-channel desiccant 1 ensures stable ventilation while guaranteeing that the desiccant can be placed alone in the connecting channel 111 with sufficient space, avoiding the risk of the desiccant bursting the multi-channel desiccant 1 after saturation, thus improving the structural stability of the multi-channel desiccant 1.

[0041] Specifically, please refer to the following: Figure 3 and Figure 4 A first waterproof and breathable membrane 14 is provided on the connecting end 1111, which seals the connecting end 1111. The first waterproof and breathable membrane 14 and the opening of the ventilation channel 112 near the connecting end 1111 are spaced apart. Based on the waterproof and breathable properties of the first waterproof and breathable membrane 14, moisture inside the lamp can pass through the first waterproof and breathable membrane 14 into the connecting channel 111, while preventing moisture or desiccant from entering the lamp interior. Furthermore, the spaced arrangement between the opening of the ventilation channel 112 and the opening of the connecting end 1111 separates the first waterproof and breathable membrane 14 from the ventilation channel 112, reducing the number of sealing points required for the first waterproof and breathable membrane 14. It also eliminates the need for an opening on the first waterproof and breathable membrane 14 corresponding to the ventilation channel 112, further reducing the risk of desiccant leakage after sealing.

[0042] Specifically, please refer to the following: Figure 5 and Figure 6The connecting channel 111 includes a first cavity 1113 and a second cavity 1114 connected together. The diameter of the first cavity 1113 is larger than the diameter of the second cavity 1114. The working end 1112 and the connecting end 1111 are located in the first cavity 1113 and the second cavity 1114 respectively, and the diameter of the working end 1112 is larger than the diameter of the connecting end 1111. Since the connecting end 1111 needs to be inserted into and connected to the lamp, the size design of the connecting end 1111 is limited. By setting the diameter of the working end 1112 to be larger than the diameter of the connecting end 1111, and the diameter of the corresponding first cavity 1113 in the working end 1112 and the connecting end 1111 is also larger than the diameter of the second cavity 1114, the space of the connecting channel 111 inside the housing 11 is further increased without affecting the sealing and stability of the multi-channel desiccant 1 connected to the lamp, thus avoiding the risk of the desiccant breaking the multi-channel desiccant 1.

[0043] Specifically, please refer to the following: Figure 4 and Figure 6 The breathing cover 12 has a receiving cavity 122, and a positioning groove 121 connects to the receiving cavity 122. The opening of the receiving cavity 122 is a vent 123. A second waterproof and breathable membrane 15 is installed inside the receiving cavity 122, and the second waterproof and breathable membrane 15 seals the vent 123. The second waterproof and breathable membrane 15 can prevent external moisture or other impurities from entering the multi-channel dehumidifier 1 while ensuring gas flow, further improving the moisture-proof performance and stability of the multi-channel dehumidifier 1. At the same time, the second waterproof and breathable membrane 15 can also play a certain role in dust prevention, extending the service life of the multi-channel dehumidifier. The second waterproof and breathable membrane 15 is set in the receiving cavity 122, which facilitates the installation and fixation of the second waterproof and breathable membrane 15.

[0044] Furthermore, please refer to the following: Figure 5 and Figure 6 A valve assembly 16 is installed within the receiving cavity 122. The valve assembly 16 includes a support frame 161, an inlet soft rubber valve 162, and an exhaust soft rubber valve 163. The support frame 161 is engaged within the receiving cavity 122, and the inlet and exhaust soft rubber valves 162 and 163 are engaged with the support frame 161. The valve assembly 16 controls the opening and closing of the ventilation channel 112, allowing stable exchange of gas between the lamp and the outside environment, preventing pressure differences between the inside and outside of the lamp from damaging it. Simultaneously, the independent intake / exhaust of the inlet and exhaust valves 162 and 163 makes it more difficult for external moisture to enter the lamp, while facilitating the expulsion of internal gas.

[0045] Specifically, please refer to Figure 4The multi-channel dehumidifier 1 also includes a sealing ring 17. A boss 113 is provided on the circumferential outer surface of the housing 11. The sealing ring 17 is fitted onto the housing 11, and the sealing ring 17 abuts against the side of the boss 113 near the connecting end 1111. The sealing ring 17 further improves the sealing performance of the multi-channel dehumidifier 1, preventing external moisture or other impurities from entering the lamp, thus further ensuring the moisture-proof performance and stability of the multi-channel dehumidifier 1. At the same time, the sealing ring 17 also acts as a shock absorber and buffer, protecting the multi-channel dehumidifier 1 from impacts and damage from the external environment, and extending the service life of the multi-channel dehumidifier 1.

[0046] Specifically, please refer to Figure 4 The boss 113 has a snap-fit ​​part 114 and a grip part 115 on both sides near the connecting end 1111 and the working end 1112, respectively. The snap-fit ​​part 114 makes it easy to snap the multi-channel dehumidifier 1 onto lamps or other lighting equipment, improving the connection stability of the multi-channel dehumidifier 1. The grip part 115 makes it easy for the user to grip the multi-port dehumidifier, thus making it easier to rotate, adjust or disassemble the multi-port dehumidifier.

[0047] Further, please refer to Figure 4 The snap-fit ​​part 114 includes a plurality of snap-fit ​​blocks arranged in a ring at intervals. Each snap-fit ​​block includes a first block 1141 and a second block 1142. The second block 1142 faces the connection end 1111 and is perpendicular to the first block 1141. The second block 1142 serves as a guide, facilitating the alignment of the multi-channel dehumidifier 1 with the adjacent connection area of ​​the lamp. At the same time, the perpendicular first block 1141 and the second block 1142 enhance the snap-fit ​​fixing effect of the multi-channel dehumidifier 1 on the lamp, further ensuring the stability and reliability of the connection between the multi-channel dehumidifier 1 and the lamp, facilitating user installation and disassembly operations, and improving ease of use.

[0048] The multi-channel dehumidifier 1 provided in the first embodiment of this utility model achieves dehumidification and anti-fogging of the internal space of the lamp by placing the moisture-absorbing element 13 in the connecting channel 111. Moisture inside the lamp enters the connecting channel 111 through the opening of the connecting end 1111 and is absorbed by the moisture-absorbing element 13. Simultaneously, a ventilation channel 112, independent of the connecting channel 111, is provided on the housing 11, allowing gas exchange between the lamp and the outside environment through the independent ventilation channel 112, avoiding damage to the lamp due to a pressure difference between the inside and outside of the lamp. The independent connecting channel 111 and ventilation channel 112, used for moisture absorption and ventilation respectively, ensure stable ventilation of the lamp while providing sufficient space for the desiccant, avoiding the risk of the desiccant saturating and breaking the multi-channel dehumidifier 1, thus improving the structural stability of the multi-channel dehumidifier 1.

[0049] To resolve the above technical issues, please refer to [link / reference]. Figure 7The second embodiment of this utility model also provides a vehicle lamp 2, which includes a lamp housing 21 and a multi-channel dehumidifier 1. The multi-channel dehumidifier 1 is connected to the lamp housing 21, and the connection end 1111 of the multi-channel dehumidifier 1 is at least partially located inside the lamp housing 21, while the working end 1112 of the multi-channel dehumidifier 1 is located outside the lamp housing 21. The vehicle lamp 2 has the same beneficial effects as the multi-channel dehumidifier 1 described above, and will not be elaborated further here.

[0050] To solve the above-mentioned technical problems, the third embodiment of this utility model also provides a vehicle, which includes a vehicle body, a headlight 2, and a multi-channel dehumidifier 1. The multi-channel dehumidifier 1 is disposed on the headlight 2, and the headlight 2 is connected to the vehicle body.
