Multi-port moisture wiper, vehicle lamp and vehicle

Abstract

This utility model specifically relates to a multi-port dehumidifier, a vehicle lamp, and a vehicle in the field of dehumidification device technology. The multi-port dehumidifier uses a separate ventilation channel on the inner wall of the housing, independent of the connecting channel, to allow gas exchange between the vehicle lamp and the outside environment. This avoids the pressure difference that can damage the vehicle lamp caused by the expansion and contraction of gas inside the lamp due to heat. Simultaneously, a moisture-absorbing component is installed within the connecting channel, and multiple ventilation holes connected to the connecting channel are provided on the circumferential side wall of the housing near the connecting end. Moisture inside the vehicle lamp can enter the connecting channel through these ventilation holes and be absorbed by the desiccant, thereby dehumidifying the interior space of the vehicle lamp. The simultaneous operation of multiple ventilation holes increases the moisture absorption area of ​​the multi-port dehumidifier, improving its absorption efficiency and preventing the problem of desiccant surface clumping and reduced absorption effect found in traditional condensers. This improves the utilization rate of the desiccant and the performance of the multi-port dehumidifier.

Description

Technical Field

[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 high-efficiency adsorption 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. Traditional condensation controllers suffer from drawbacks such as clogged penetration channels after the desiccant surface hardens, leading to a significant reduction in subsequent moisture absorption rates. Furthermore, limited by insufficient effective area and narrow ventilation channels, they struggle to cope with high humidity environments and the need for subsequent fog dissipation, resulting in low moisture absorption efficiency.

[0006] Preferably, a fixing groove is provided on the side of the ventilation channel near the working end, and a ventilation component is provided in the fixing groove. The ventilation component includes a ventilation valve and a pressure ring. The ventilation valve is placed in the fixing groove to seal the ventilation channel, and the two sides of the pressure ring abut against the ventilation valve and the top cover, respectively.

[0007] Preferably, an installation groove is provided on the side of the top cover away from the shell, the vent is connected to the installation groove, a second waterproof and breathable membrane is provided in the installation groove, and the second waterproof and breathable membrane seals the vent.

[0008] Preferably, a third waterproof and breathable membrane or lower cover is provided on the connecting end, the third waterproof and breathable membrane or lower cover seals the connecting end, and the lower cover is detachably connected to the shell or integrally formed.

[0009] Preferably, the multi-port 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.

[0010] Preferably, 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, with the snap-fit ​​part located between adjacent ventilation zones.

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

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

[0013] Compared with the prior art, the multi-port dehumidifier, vehicle light, and vehicle provided by this utility model have the following beneficial effects: 1. The multi-port dehumidifier provided in this utility model embodiment is designed to dehumidify and prevent fogging of vehicle lights or other indoor and outdoor lighting facilities. In use, the multi-port dehumidifier is connected to the vehicle light. The housing of the multi-port dehumidifier is provided with a connecting channel that runs through both ends of the housing. The side of the housing near the connecting end of the connecting channel is placed inside the vehicle light, and the side of the housing near the working end of the connecting channel is placed in the external environment. The inner wall of the housing is also provided with a ventilation channel independent of the connecting channel. One end of the ventilation channel is open near the connecting end, and the other end of the ventilation channel is open to the vent. When the gas inside the vehicle light expands and contracts due to heat, the vehicle light and the outside world exchange gases through the independent ventilation channel, avoiding the formation of a pressure difference between the inside and outside of the vehicle light and causing damage to the vehicle light.

[0014] Simultaneously, a moisture-absorbing component is installed within the connecting channel, and multiple vents connected to the connecting channel are provided on the circumferential sidewall of the housing near the connecting end. Moisture inside the headlight can enter the connecting channel through these vents and be absorbed by the desiccant, thereby dehumidifying the internal space of the headlight and preventing excessive condensation that could affect its normal operation. Furthermore, the presence of multiple vents on the circumferential sidewall of the housing increases the moisture absorption area of ​​the multi-port desiccant, improving its efficiency. Moisture entering the connecting channel through different vents is also absorbed by the desiccant at the corresponding location. The desiccant can absorb moisture from multiple angles, avoiding the problem of desiccant clumping on the surface after absorption, which hinders moisture absorption and significantly reduces its effectiveness, as seen in traditional condensers. This improves the utilization rate of the desiccant and the overall moisture absorption capacity of the multi-port desiccant.

[0015] 2. In this embodiment of the utility model, a first waterproof and breathable membrane is also provided on the vent hole. The first waterproof and breathable membrane seals the vent hole. The desiccant in the connecting channel will reach saturation after absorbing a large amount of moisture. In addition, excess water in the desiccant may condense into water droplets in the connecting channel. Through the waterproof and breathable performance of the first waterproof and breathable membrane, water droplets in the connecting channel can be prevented from flowing out of the vent hole into the headlight. At the same time, it will not affect the moisture in the headlight entering the connecting channel, thus avoiding short circuits or lighting effects caused by moisture accumulation inside the headlight, and improving the safety and reliability of the multi-port desiccant.

[0016] 3. In this embodiment of the utility model, the housing has multiple ventilated areas spaced in a ring. Each ventilated area includes multiple ventilated holes arranged in a grid pattern. This arrangement allows for a larger moisture absorption area on the housing, enabling moisture from inside the vehicle headlights to enter the connecting channel, thus improving the moisture absorption efficiency of the multi-port dehumidifier. Furthermore, a separate first waterproof and breathable membrane is provided for each ventilated area, and the grid-arranged ventilated holes provide support for the first waterproof and breathable membrane, reducing the assembly difficulty of the first waterproof and breathable membrane and ensuring its stable operation. This avoids the problem of reduced sealing performance due to improper assembly of the first waterproof and breathable membrane, thereby improving the waterproof and breathable performance of the multi-port dehumidifier.

[0017] 4. In this embodiment of the utility model, a fixing groove is provided on the side of the ventilation channel near the working end, and a ventilation component is provided in the fixing groove. The ventilation component includes a ventilation valve and a pressure ring. The ventilation valve is placed in the fixing groove to seal the ventilation channel. The two sides of the pressure ring abut against the ventilation valve and the top cover, respectively. By setting the ventilation component, the gas flow capacity of the ventilation channel is controlled, so that the gas in the headlight can be stably exchanged with the outside through the ventilation channel, avoiding the formation of a pressure difference between the inside and outside of the headlight and causing damage to the headlight.

[0018] 5. In this embodiment of the invention, a mounting groove is provided on the side of the top cover away from the housing. The vent is connected to the mounting groove, and a second waterproof and breathable membrane is provided inside the mounting groove. 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-port dehumidifier, further improving the moisture-proof performance and stability of the multi-port dehumidifier. Simultaneously, the second waterproof and breathable membrane also provides some dust protection, extending the service life of the multi-port dehumidifier.

[0019] 6. In this embodiment of the utility model, a third waterproof and breathable membrane or lower cover is provided on the connecting end. The third waterproof and breathable membrane or lower cover seals the connecting end. The lower cover is detachably connected to the housing or integrally formed. When the third waterproof and breathable membrane is provided on the connecting end, moisture inside the vehicle lamp can enter the connecting channel through the opening of the connecting end via the third waterproof and breathable membrane, further increasing the moisture absorption area of ​​the multi-port desiccant and improving its moisture absorption efficiency. When the lower cover is detachably connected to the housing or integrally formed, it can support the desiccant in the connecting channel, preventing it from swaying within the channel and ensuring sufficient contact between the desiccant and the moisture inside the vehicle lamp, thus improving the moisture absorption effect. Simultaneously, the lower cover also provides a certain degree of sealing to the connecting channel, preventing the desiccant from leaking into the vehicle lamp and affecting its performance.

[0020] 7. In this embodiment of the utility model, the multi-port 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-port dehumidifier, preventing external moisture or other impurities from entering the interior of the vehicle headlight, thus further ensuring the moisture-proof performance and stability of the multi-port dehumidifier. Simultaneously, the sealing ring also acts as a shock absorber and buffer, protecting the multi-port dehumidifier from impacts and damage from the external environment, and extending its service life.

[0021] 8. 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 is located between adjacent ventilation areas. The snap-fit ​​part can be used to snap the multi-port dehumidifier onto the vehicle headlight or other lighting equipment, thereby improving the connection stability of the multi-port dehumidifier. The gripping part can make it easier for the user to grip the multi-port dehumidifier, thereby making it easier to rotate, adjust or disassemble the multi-port dehumidifier.

[0022] 9. This utility model also provides a vehicle light, which includes a light box and a multi-port dehumidifier. The multi-port dehumidifier is connected to the light box, and the connecting end of the multi-port dehumidifier is at least partially located inside the light box. The working end of the multi-port dehumidifier is located outside the light box. The vehicle light has the same beneficial effects as the multi-port dehumidifier described above, which will not be elaborated here.

[0023] 10. This utility model also provides a vehicle, which includes a vehicle body, headlights and a multi-port dehumidifier. The multi-port dehumidifier is mounted on the headlights, and the headlights are connected to the vehicle body. The vehicle has the same beneficial effects as the aforementioned multi-port dehumidifier, which will not be described in detail here. Attached Figure Description

[0036] 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 high-efficiency adsorption 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. Traditional condensation controllers suffer from drawbacks such as clogged penetration channels after the desiccant surface hardens, leading to a significant reduction in subsequent moisture absorption rates. Furthermore, limited by insufficient effective area and narrow ventilation channels, they struggle to cope with high humidity environments and the need for subsequent fog dissipation, resulting in low moisture absorption efficiency.

[0037] To resolve the above technical issues, please refer to the following: Figures 1-3The first embodiment of this utility model provides a multi-port desiccant 1, which includes a housing 11, a desiccant 12, and a top cover 13. The housing 11 is provided with a connecting channel 111 that passes through both ends of the housing 11, and the desiccant 12 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 top cover 13 is connected to the housing 11 and closes the working end 1112. The top cover 13 is provided with a vent 131. The inner wall of the housing 11 is provided with a vent channel 112 that is independent of the connecting channel 111. One end of the vent channel 112 is open near the connecting end 1111, and the other end of the vent channel 112 is open and connected to the vent 131. The circumferential side wall of the housing 11 near the connecting end 1111 is provided with a plurality of vent holes 113 that are connected to the connecting channel 111.

[0038] 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.

[0039] The multi-port dehumidifier 1 provided in the first embodiment of the utility model is intended to dehumidify and prevent fogging of lamps or other indoor and outdoor lighting facilities. As one implementation method, the multi-port dehumidifier 1 is connected to the lamp. The housing 11 of the multi-port dehumidifier 1 is provided with a connecting channel 111 that runs through 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. The inner wall of the housing 11 is also provided with a ventilation channel 112 that is independent of the connecting channel 111. One end of the ventilation channel 112 is open near the connecting end 1111, and the other end of the ventilation channel 112 is open to the vent 131. When the gas inside the lamp expands and contracts due to heat, 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 and causing damage to the lamp.

[0040] Meanwhile, a moisture-absorbing element 12 is installed inside the connecting channel 111, and multiple vent holes 113 connected to the connecting channel 111 are provided on the circumferential sidewall of the housing 11 near the connecting end 1111. Moisture inside the lamp can enter the connecting channel 111 through the vent holes 113 and be absorbed by the desiccant, thereby dehumidifying the internal space of the lamp and preventing excessive moisture inside the lamp from condensing into water droplets, which would affect the normal use of the lamp. In addition, multiple vent holes 113 are provided on the circumferential sidewall of the housing 11. The simultaneous operation of multiple vent holes 113 increases the moisture absorption area of ​​the multi-port desiccant 1 and improves the moisture absorption efficiency. Moisture entering the connecting channel 111 from different vent holes 113 is also absorbed by the desiccant at the corresponding position. The desiccant can adsorb moisture from multiple angles, avoiding the problem in traditional condensers where the desiccant clumps on the surface after absorbing moisture, blocking the adsorption of moisture and greatly reducing the moisture absorption effect. This improves the utilization rate of the desiccant and the moisture absorption capacity of the multi-port desiccant 1.

[0041] Specifically, please refer to Figure 3 A first waterproof and breathable membrane 14 is also provided on the vent 113, which seals the vent 113. The desiccant in the connecting channel 111 will reach saturation after absorbing a large amount of moisture. In addition, excess moisture in the desiccant may condense into water droplets in the connecting channel 111. The waterproof and breathable properties of the first waterproof and breathable membrane 14 can prevent water droplets in the connecting channel 111 from flowing out into the lamp through the vent 113, while not affecting the entry of moisture into the connecting channel 111. This avoids short circuits or lighting problems caused by moisture accumulation inside the lamp, and improves the safety and reliability of the multi-port desiccant 1.

[0042] Furthermore, please refer to the following: Figure 1 and Figure 3 The housing 11 is cylindrical, with multiple venting zones 114 spaced annularly on its sidewalls. Each venting zone 114 includes multiple venting holes 113 arranged in a grid pattern. A first waterproof and breathable membrane 14 is attached to each venting zone 114 and is located on the outside of the housing 11. This arrangement allows for a larger moisture-absorbing area on the housing 11, enabling moisture from the lamp to enter the connecting channel 111, thus improving the moisture absorption efficiency of the multi-port dehumidifier 1. Furthermore, a first waterproof and breathable membrane 14 is individually positioned for each venting zone 114, and the grid-like venting holes 113 provide support for the first waterproof and breathable membrane 14, reducing assembly difficulty and ensuring stable operation. This prevents improper assembly from causing a decrease in sealing performance and improves the waterproof and breathable performance of the multi-port dehumidifier 1.

[0043] Specifically, please refer to Figure 3 A fixing groove 1121 is provided on one side of the ventilation channel 112 near the working end 1112. A ventilation component 115 is provided in the fixing groove 1121. The ventilation component 115 includes a ventilation valve 1151 and a pressure ring 1152. The ventilation valve 1151 is placed in the fixing groove 1121 to close the ventilation channel 112. The two sides of the pressure ring 1152 abut against the ventilation valve 1151 and the top cover 13, respectively. Optionally, the vent valve 1151 is configured as a one-way valve. When there is a small pressure difference between the inside and outside of the lamp, the gas can freely exchange gases through the one-way valve. When the lamp cools rapidly and forms a strong negative pressure, the one-way valve opens a larger vent, allowing a large amount of air to be drawn in instantly, preventing the lamp housing from being sucked down or the sealing ring from deforming. At the same time, when liquid water enters the vent channel 112, the vent valve 1151 will close tightly under the action of water pressure, preventing the liquid water from rushing in. This allows the gas inside the lamp to be stably exchanged with the outside through the vent channel 112, avoiding damage to the lamp caused by the pressure difference between the inside and outside of the lamp, and ensuring the stability of the venting capacity of the vent channel 112.

[0044] Specifically, please refer to Figure 3 A mounting groove 132 is provided on the side of the top cover 13 opposite to the housing 11. A vent 131 connects to the mounting groove 132. A second waterproof and breathable membrane 15 is installed within the mounting groove 132, sealing the vent 131. The second waterproof and breathable membrane 15 ensures airflow while preventing external moisture or other impurities from entering the multi-port dehumidifier 1, further improving its moisture-proof performance and stability. Simultaneously, the second waterproof and breathable membrane 15 also provides some dust protection, extending the service life of the multi-port dehumidifier 1.

[0045] Specifically, please refer to the following: Figure 3 and Figure 4 A third waterproof and breathable membrane 17 or a lower cover 16 is provided on the connection end 1111. When the third waterproof and breathable membrane 17 is provided on the connection end 1111, the third waterproof and breathable membrane 17 closes the connection end 1111. Moisture inside the lamp can enter the connection channel 111 through the opening of the connection end 1111 via the third waterproof and breathable membrane 17, further increasing the moisture absorption area of ​​the multi-port dehumidifier 1 and improving the moisture absorption efficiency of the multi-port dehumidifier 1.

[0046] When a lower cover 16 is provided on the connecting end 1111, the lower cover 16 seals the connecting end 1111. The lower cover 16 is detachably connected to the housing 11 or integrally formed. When a lower cover 16 is provided on the connecting end 1111 and is detachably connected to or integrally formed with the housing 11, the lower cover 16 can support the desiccant in the connecting channel 111, preventing the desiccant from shaking in the connecting channel 111, ensuring sufficient contact between the desiccant and the moisture inside the lamp, and improving the moisture absorption effect. At the same time, the lower cover 16 can also provide a certain degree of sealing to the connecting channel 111, preventing the desiccant from leaking into the lamp and affecting the lamp's performance.

[0047] Specifically, please refer to Figure 2 The multi-port dehumidifier 1 also includes a sealing ring 18. A boss 116 is provided on the circumferential outer surface of the housing 11. The sealing ring 18 is fitted onto the housing 11, and the sealing ring 18 abuts against the side of the boss 116 near the connecting end 1111. The sealing ring 18 further improves the sealing performance of the multi-port dehumidifier 1, preventing external moisture or other impurities from entering the interior of the lamp, thus further ensuring the moisture-proof performance and stability of the multi-port dehumidifier 1. At the same time, the sealing ring 18 also acts as a shock absorber and buffer, protecting the multi-port dehumidifier 1 from impacts and damage from the external environment, and extending the service life of the multi-port dehumidifier 1.

[0048] Specifically, please refer to Figure 2 The boss 116 has a snap-fit ​​part 117 and a gripping part 118 respectively on both sides near the connecting end 1111 and the working end 1112. The snap-fit ​​part 117 is located between adjacent ventilation areas 114. The snap-fit ​​part 117 makes it easy to snap the multi-port dehumidifier 1 onto lamps or other lighting equipment, improving the connection stability of the multi-port dehumidifier 1. The gripping part 118 makes it easy for the user to grip the multi-port dehumidifier 1, thus making it easier to rotate, adjust or disassemble the multi-port dehumidifier 1.

[0049] The multi-port dehumidifier 1 provided in the first embodiment of this utility model has a separate venting channel 112 on the inner wall of the housing 11, which allows the lamp and the outside environment to exchange gases through the independent venting channel 112. This avoids the pressure difference between the inside and outside of the lamp that could damage the lamp when the gas inside the lamp expands and contracts due to heat. At the same time, a desiccant 12 is provided in the connecting channel 111, and multiple vent holes 113 connected to the connecting channel 111 are provided on the circumferential side wall of the housing 11 near the connecting end 1111. Moisture inside the lamp can enter the connecting channel 111 through the vent holes 113 and be absorbed by the desiccant, thereby dehumidifying the internal space of the lamp. The simultaneous operation of multiple vent holes 113 increases the moisture absorption area of ​​the multi-port dehumidifier 1 and improves the moisture absorption efficiency. After the moisture enters the connecting channel 111 through different vent holes 113, it is absorbed by the desiccant at the corresponding position. These desiccants can absorb moisture from multiple angles, preventing the problem of desiccant surface clumping in traditional condensers, thus avoiding weakened moisture absorption and improving the utilization rate of the desiccant and the performance of the desiccant.

[0050] To resolve the above technical issues, please refer to [link / reference]. Figure 5 The second embodiment of this utility model also provides a vehicle lamp 2, which includes a lamp housing 21 and a multi-port dehumidifier 1. The multi-port dehumidifier 1 is connected to the lamp housing 21, and the connecting end 1111 of the multi-port dehumidifier 1 is at least partially located inside the lamp housing 21, while the working end 1112 of the multi-port dehumidifier 1 is located outside the lamp housing 21. The vehicle lamp 2 has the same beneficial effects as the multi-port dehumidifier 1 described above, and will not be elaborated further here.

[0051] 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-port dehumidifier 1. The multi-port dehumidifier 1 is mounted on the headlight 2, and the headlight 2 is connected to the vehicle body.
