Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a dehumidification device, a vehicle lamp, and a vehicle. Background Art

[0002] A vehicle typically consists of a body and headlights mounted on it. Headlights provide the driver with a clear field of vision, ensuring driving safety. Drivers can also communicate with other vehicles and pedestrians through various light signals, ensuring traffic safety. Headlight housings and other components are typically made of plastic, which absorbs water. New headlights also contain moisture during the production process. Therefore, moisture gradually accumulates inside the housing during use. When this moisture accumulates to a certain level, it forms fog, which affects the lighting effect.

[0003] In the prior art, a dehumidifier is typically installed inside a headlight to remove moisture from the headlight housing. However, the dehumidification capacity of the prior art dehumidifier is limited, and a large amount of moisture may still accumulate inside the headlight housing, resulting in poor dehumidification performance. Summary of the Invention

[0004] The purpose of this application is to provide a dehumidification device, a vehicle lamp and a vehicle, aiming to solve the problem of how to improve the dehumidification effect of the dehumidification device in the vehicle lamp.

[0005] In a first aspect, a dehumidification device is provided, which includes a shell, a dehumidification component and a switching assembly, the shell is provided with a accommodating chamber and a first through hole and a second through hole connected to the accommodating chamber; the dehumidification component is provided in the accommodating chamber and can absorb moisture through the first through hole and discharge moisture through the second through hole; the switching assembly is provided in the accommodating chamber and can move between a first state and a second state, when the switching assembly is in the first state, the switching assembly blocks the first through hole and opens the second through hole; when the switching assembly is in the second state, the switching assembly opens the first through hole and blocks the second through hole.

[0006] In this way, when the switching assembly is in the second state, the first through-hole is open and the second through-hole is closed. The dehumidifying element can absorb moisture from the space connected to the first through-hole, such as the interior space of a lampshade, through the first through-hole, to keep the space connected to the first through-hole dry and prevent fogging. After moisture absorption from the space connected to the first through-hole is completed or when the moisture absorbed by the dehumidifying element needs to be removed, the switching assembly is switched to the first state. In this case, the first through-hole is closed and the second through-hole is opened. The dehumidifying element can communicate with the outside world through the second through-hole, thereby discharging the absorbed moisture to the outside world through the second through-hole, allowing the dehumidifying element to absorb moisture again.

Moreover, when the switching component switches to the first state, the first through hole is closed, and the space connected to the first through hole is isolated from the outside world, which can prevent external moisture from entering the space connected to the first through hole through the first through hole.

[0062] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 1000 provided in an embodiment of the present application. This application provides a vehicle 1000, wherein the vehicle 1000 can be a pure gasoline vehicle, a pure electric vehicle, a hybrid vehicle, etc. The vehicle 1000 can also be a car, a bus, a van, a truck, a trailer, etc.

[0063] Vehicle 1000 includes a body 100 and a headlight 200 mounted on body 100. Body 100 is used to carry people or goods, and headlight 200 is connected to body 100. Headlight 200 provides illumination, providing the driver with a clear field of vision and ensuring driving safety. Headlight 200 also provides warning and signaling functions, allowing the driver to communicate with other vehicles 1000 and pedestrians through various light signals, ensuring traffic safety. The headlight 200 can be connected to body 100 by screws, snaps, adhesives, or the like.

[0064] See also Figures 2 to 4 , Figure 2 is a structural diagram of a dehumidification device 30 in a vehicle lamp 200 in a first state. Figure 3 for Figure 2 The structure diagram of the dehumidification device 30 in the vehicle lamp 200 is shown in the second state. Figure 4 2 is a schematic structural diagram of another vehicle lamp 200. In some embodiments, the vehicle lamp 200 may include a lampshade 10, a bulb 20, and a dehumidification device 30. The bulb 20 is disposed in the lampshade 10. The lampshade 10 has a mounting hole connected to the outside, and the dehumidification device 30 is disposed in the mounting hole.

[0065] In this way, by placing the bulb 20 within the lampshade 10, the lampshade 10 can protect the bulb 20 to prevent damage to the bulb 20. By providing a mounting hole in the lampshade 10 that connects to the outside world and arranging the dehumidifier 30 in the mounting hole, the assembly of the dehumidifier 30 and the lampshade 10 can be facilitated to improve assembly efficiency. In addition, the dehumidifier 30 can directly connect the internal environment of the bulb 20 with the external environment through the mounting hole, thereby preventing the formation of fog inside the headlight 20 due to temperature changes.

[0066] The dehumidification device 30 can keep the interior of the headlight 200 in a dry state, preventing fog from being generated inside the headlight 200 due to temperature changes. The fog not only affects the appearance and optical performance of the headlight 200, but also damages the electronic components inside it, causing the electronic components to fail, further affecting the service life of the headlight 200.

[0067] In some examples, a sealing structure such as a sealing ring or sealant is provided between the outer shell 11 of the dehumidification device 30 and the inner wall surface of the mounting hole to prevent moisture from entering the lampshade 10 through the gap between the outer shell 11 of the dehumidification device 30 and the inner wall surface of the mounting hole.

[0068] In some examples, part of the dehumidification device 30 is located in the mounting hole, and another part is located inside the lampshade 10 or outside the lampshade 10 .

[0069] In some embodiments, see Figures 5 to 9 , Figure 5 for Figure 2 The schematic diagram of the exploded structure of the dehumidification device 30 in the vehicle lamp 200 is shown. Figure 6 for Figure 4 The schematic diagram of the exploded structure of the dehumidification device 30 in the vehicle lamp 200 is shown. Figure 7 for Figure 2 The schematic structural diagram of the dehumidification device 30 in the vehicle lamp 200 is shown. Figure 8 for Figure 3 The schematic structural diagram of the dehumidification device 30 in the vehicle lamp 200 is shown. Figure 9 for Figure 4 The following figure shows the structure of the dehumidifier 30 in the vehicle lamp 200. The dehumidifier 30 comprises a housing 1, a dehumidifier, and a switching assembly 3. The housing 1 defines a receiving chamber 1A, and a first through-hole 1B and a second through-hole 1C communicating with the receiving chamber 1A. When the dehumidifier 30 is installed in the mounting hole of the lampshade 10, the first through-hole 1B communicates with the interior of the lampshade 10, and the second through-hole 1C communicates with the exterior of the lampshade 10.

[0070] The dehumidifying component 2 is arranged in the accommodating cavity 1A, and can absorb moisture through the first through hole 1B, and discharge moisture through the second through hole 1C; the switching component 3 is arranged in the accommodating cavity 1A, and can move between a first state and a second state. When the switching component 3 is in the first state, the switching component 3 blocks the first through hole 1B and opens the second through hole 1C; when the switching component 3 is in the second state, the switching component 3 opens the first through hole 1B and blocks the second through hole 1C.

[0071] In this way, when the switching assembly 3 is in the second state, the first through hole 1B is open and the second through hole 1C is closed. The dehumidifying element 2 can absorb moisture from the space connected to the first through hole 1B, such as the interior space of the lampshade 10, through the first through hole 1B, to keep the space connected to the first through hole 1B dry and prevent fogging. After the moisture absorption in the space connected to the first through hole 1B is completed or the moisture absorbed by the dehumidifying element 2 needs to be removed, the switching assembly 3 is switched to the first state. In this case, the first through hole 1B is closed and the second through hole 1C is opened. The dehumidifying element 2 can communicate with the outside world through the second through hole 1C, thereby discharging the absorbed moisture to the outside world through the second through hole 1C, allowing the dehumidifying element 2 to absorb moisture again. This prevents moisture from accumulating in the space connected to the first through hole 1B, such as the interior space of the lampshade 10, and causing fogging. Moreover, when the switching component 3 switches to the first state, the first through hole 1B is closed, and the space connected to the first through hole 1B is isolated from the outside world, which can prevent external moisture from entering the space connected to the first through hole 1B through the first through hole 1B, that is, no moisture will enter the space connected to the first through hole 1B during the process of the dehumidification component 2 discharging moisture through the second through hole 1C, which can improve the dehumidification effect of the dehumidification component 2 on the space connected to the first through hole 1B.

[0072] In some embodiments, the switching component 3 includes a driving member 31 and a blocking structure 32. The driving member 31 is transmission-connected to the blocking structure 32 for driving the blocking structure 32 to move so that the switching component 3 switches between the first state and the second state. When the switching component 3 is in the first state, the blocking structure 32 blocks the first through hole 1B and opens the second through hole 1C. When the switching component 3 is in the second state, the blocking structure 32 opens the first through hole 1B and blocks the second through hole 1C.

[0073] In this way, when the switching assembly 3 is in the second state, the driving member 31 drives the blocking structure 32 to open the first through hole 1B and close the second through hole 1C. The dehumidifying element 2 can absorb moisture from the space connected to the first through hole 1B, such as the interior space of the lampshade 10, through the first through hole 1B, to keep the space connected to the first through hole 1B dry and prevent fogging. After the moisture absorption of the space connected to the first through hole 1B is completed or the moisture absorbed by the dehumidifying element 2 needs to be removed, the switching assembly 3 is switched to the first state. At this time, the driving member 31 drives the blocking structure 32 to close the first through hole 1B and open the second through hole 1C. The dehumidifying element 2 can communicate with the outside world through the second through hole 1C, thereby discharging the absorbed moisture to the outside world through the second through hole 1C, allowing the dehumidifying element 2 to absorb moisture again. This can prevent moisture from accumulating in the space connected to the first through hole 1B, such as the interior space of the lampshade 10, and causing fogging. In this way, the working reliability of the dust removal device can be improved through the cooperation of the driving member 31 and the blocking structure 32. Under the driving action of the driving member 31, the blocking structure 32 quickly switches between the first state and the second state to ensure the continuity of dehumidification of the dust removal device.

[0074] In some examples, the first through hole 1B and the second through hole 1C can be arranged relative to each other, the driving member 31 can be an electric push rod, and the blocking structure 32 can be a flexible column, such as a rubber column, a latex column, a silicone column, etc. The electric push rod pushes the flexible column to move back and forth between the first through hole 1B and the second through hole 1C, so that the flexible column blocks the second through hole 1C. At this time, the first through hole 1B is opened, and the dehumidifying component 2 can absorb moisture from the space connected to the first through hole 1B, such as the internal space of the lampshade 10, through the first through hole 1B to keep the space connected to the first through hole 1B dry and prevent fogging. After the moisture absorption of the space connected to the first through hole 1B is completed or the moisture absorbed by the dehumidifying component 2 needs to be discharged, the switching component 3 is switched to the first state. At this time, the flexible column blocks the first through hole 1B, and the second through hole 1C is opened. The dehumidifying component 2 can be connected to the outside through the second through hole 1C, thereby discharging the absorbed moisture to the outside through the second through hole 1C, so that the dehumidifying component 2 can absorb moisture again.

[0075] In some examples, the housing 1 can be a cylindrical structure, with the first through hole 1B and the second through hole 1C spaced apart along the circumference of the housing 1. The driving member 31 can be a rotary motor, and the blocking structure 32 can be a circular structure, a fan-shaped structure, or the like. The outer circumference of the blocking structure 32 abuts the inner circumference of the housing 1. The driving member 31 drives the blocking structure 32 to rotate about the axis of the housing 1. When the blocking structure 32 rotates to the second through hole 1C, it covers the second through hole 1C and avoids the first through hole 1B, thereby blocking the second through hole 1C and opening the first through hole 1B. The dehumidifying element 2 can absorb moisture from a space connected to the first through hole 1B, such as the interior space of the lampshade 10, through the first through hole 1B, thereby keeping the space connected to the first through hole 1B dry and preventing fogging. After moisture absorption is completed in the space connected to the first through hole 1B, or when moisture absorbed by the dehumidifying element 2 needs to be removed, the switching assembly 3 is switched to the first state. When the sealing structure 32 rotates to the first through hole 1B, it covers the first through hole 1B and avoids the second through hole 1C to seal the first through hole 1B and open the second through hole 1C. The dehumidification component 2 can be connected to the outside through the second through hole 1C, thereby discharging the absorbed moisture to the outside through the second through hole 1C, so that the dehumidification component 2 can absorb moisture again, thereby preventing moisture from accumulating and fogging in the space connected to the first through hole 1B, such as the internal space of the lampshade 10.

[0076] In some embodiments, the driving member 31 includes an output shaft 311, and the blocking structure 32 includes a first blocking member 321 and a second blocking member 322. The first blocking member 321 and the second blocking member 322 are both connected to the output shaft 311, and the driving member 31 is used to drive the first blocking member 321 and the second blocking member 322 to move; when the switching component 3 is in the first state, the first blocking member 321 blocks the first through hole 1B, and the second blocking member 322 opens the second through hole 1C; when the switching component 3 is in the second state, the first blocking member 321 opens the first through hole 1B, and the second blocking member 322 blocks the second through hole 1C.

[0077] In this way, the power output by the driving member 31 can drive the first blocking member 321 and the second blocking member 322 to move via the output shaft 311. Through the alternating blocking action of the first blocking member 321 and the second blocking member 322, at least one of the first through hole 1B and the second through hole 1C can be blocked. Specifically, when the switching assembly 3 is in the second state, the first blocking member 321 opens the first through hole 1B, and the second blocking member 322 blocks the second through hole 1C. The dehumidifying member 2 can absorb moisture from the space connected to the first through hole 1B, such as the interior space of the lampshade 10, through the first through hole 1B, thereby keeping the space connected to the first through hole 1B dry and preventing fogging. After the moisture absorption of the space connected to the first through hole 1B is completed or the moisture absorbed by the dehumidifying component 2 needs to be removed, the switching component 3 is switched to the first state. At this time, the first through hole 1B is closed and the second through hole 1C is opened. The dehumidifying component 2 can be connected to the outside through the second through hole 1C, thereby discharging the absorbed moisture to the outside through the second through hole 1C, so that the dehumidifying component 2 can absorb moisture again. This can prevent moisture from accumulating and fogging in the space connected to the first through hole 1B, such as the internal space of the lampshade 10.

[0078] In some examples, the power output by the driver 31 can drive the first and second blocking members 321 and 322 to translate along their axial directions via the output shaft 311. Alternatively, the power output by the driver 31 can drive the first and second blocking members 321 and 322 to rotate about the axis of the output shaft 311. When the switching assembly 3 is in the second state, the driver 31 drives the first blocking member 321 to open the first through hole 1B, and the second blocking member 322 to block the second through hole 1C. The dehumidifying member 2 can absorb moisture from a space connected to the first through hole 1B, such as the interior space of the lampshade 10, through the first through hole 1B, thereby keeping the space connected to the first through hole 1B dry and preventing fogging. After the moisture absorption of the space connected to the first through hole 1B is completed or the moisture absorbed by the dehumidifying component 2 needs to be removed, the switching component 3 is switched to the first state, the driving component 31 drives the first blocking component 321 to block the first through hole 1B, and drives the second blocking component 322 to open the second through hole 1C. The dehumidifying component 2 can be connected to the outside through the second through hole 1C, thereby discharging the absorbed moisture to the outside through the second through hole 1C, so that the dehumidifying component 2 can absorb moisture again, thereby preventing moisture from accumulating and fogging in the space connected to the first through hole 1B, such as the internal space of the lampshade 10.

[0079] In some examples, the first through hole 1B and the second through hole 1C can be provided on the peripheral wall of the housing 1. When the switching assembly 3 is in the second state, the driving member 31 drives the first blocking member 321 to open the first through hole 1B, and the second blocking member 322 blocks the second through hole 1C. The dehumidifying member 2 can absorb moisture from the space connected to the first through hole 1B, such as the interior space of the lampshade 10, through the first through hole 1B to keep the space connected to the first through hole 1B dry and prevent fogging. After the moisture absorption of the space connected to the first through hole 1B is completed or the moisture absorbed by the dehumidifying member 2 needs to be discharged, the switching assembly 3 is switched to the first state, the first through hole 1B is closed, and the second through hole 1C is opened. The dehumidifying member 2 can communicate with the outside world through the second through hole 1C, thereby discharging the absorbed moisture to the outside world through the second through hole 1C, so that the dehumidifying member 2 can absorb moisture again. This can prevent moisture from accumulating in the space connected to the first through hole 1B, such as the interior space of the lampshade 10, and causing fogging.

[0080] In some examples, the first through hole 1B and the second through hole 1C may also be provided on the end surface. When the switching assembly 3 is in the second state, the driving member 31 drives the first blocking member 321 to open the first through hole 1B, and the second blocking member 322 blocks the second through hole 1C. The dehumidifying member 2 can absorb moisture from the space connected to the first through hole 1B, such as the interior space of the lampshade 10, through the first through hole 1B, to keep the space connected to the first through hole 1B dry and prevent fogging. After the moisture absorption of the space connected to the first through hole 1B is completed or the moisture absorbed by the dehumidifying member 2 needs to be discharged, the switching assembly 3 is switched to the first state, the first through hole 1B is closed, and the second through hole 1C is opened. The dehumidifying member 2 can communicate with the outside world through the second through hole 1C, thereby discharging the absorbed moisture to the outside world through the second through hole 1C, so that the dehumidifying member 2 can absorb moisture again. This can prevent moisture from accumulating in the space connected to the first through hole 1B, such as the interior space of the lampshade 10, and causing fogging.

[0081] In some embodiments, the shell 1 includes an outer shell 11, a first cover body 12 and a second cover body 13. The outer shell 11 is provided with a circulation channel 11A. The first cover body 12 and the second cover body 13 are both connected to the outer shell 11, and along the axial direction of the circulation channel 11A, the first cover body 12 and the second cover body 13 are spaced apart. The first cover body 12, the second cover body 13 and the outer shell 11 define at least a portion of the accommodating cavity 1A; the first through hole 1B is provided in the first cover body 12, and the second through hole 1C is provided in the second cover body 13.

[0082] In this way, by arranging the first cover body 12 and the second cover body 13 axially spaced apart along the circulation channel 11A, the first cover body 12, the second cover body 13 and the outer shell 11 can define at least a portion of the accommodating cavity 1A, and the first through hole 1B is provided in the first cover body 12, and the second through hole 1C is provided in the second cover body 13, so that moisture can be connected to and isolated from the internal environment and the external environment of the lampshade 10 through the first through hole 1B and the second through hole 1C.

[0083] In addition, by connecting both the first cover 12 and the second cover 13 to the housing 11 , the installation and maintenance of the dehumidification device 30 can be facilitated.

[0084] In some examples, the first cover 12 and the second cover 13 are disposed inside the circulation channel 11A. In this case, the first cover 12, the second cover 13, and the housing 11 define a portion of the accommodating chamber 1A. In other examples, the first cover 12 and the second cover 13 are disposed outside the circulation channel 11A. In this case, the first cover 12, the second cover 13, and the housing 11 define the accommodating chamber 1A. Both arrangements allow moisture to communicate with and isolate the internal and external environments of the accommodating chamber through the first through-hole 1B and the second through-hole 1C.

[0085] In some embodiments, the first blocking member 321 is disposed on one side of the first through hole 1B in the axial direction of the circulation channel 11A; the second blocking member 322 is disposed on one side of the second through hole 1C in the axial direction of the circulation channel 11A. In other words, the first blocking member 321 can be disposed on the left or right side of the first through hole 1B in the first cover 12 in the axial direction of the circulation channel 11A; the second blocking member 322 can also be disposed on the left or right side of the second through hole 1C in the second cover 13 in the axial direction of the circulation channel 11A.

[0086] In this way, by disposing the first blocking member 321 on one side of the first through hole 1B in the axial direction of the circulation channel 11A, and the second blocking member 322 on one side of the second through hole 1C in the axial direction of the circulation channel 11A, the power output by the driving member 31 can drive the first blocking member 321 and the second blocking member 322 to move axially along the circulation channel 11A via the output shaft 311, so that at least one of the first through hole 1B and the second through hole 1C is in a blocked state. When the driving member 31 pushes the first blocking member 321 and the second blocking member 322 to move along the circulation channel 11A toward the second cover 13, the first blocking member 321 opens the first through hole 1B and the second blocking member 322 blocks the second through hole 1C. The dehumidifying member 2 can absorb moisture from the space connected to the first through hole 1B, such as the interior space of the lampshade 10, through the first through hole 1B, thereby keeping the space connected to the first through hole 1B dry and preventing fogging. After the moisture absorption of the space connected to the first through hole 1B is completed or the moisture absorbed by the dehumidification component 2 needs to be removed, the switching component 3 is switched to the first state, and the driving component 31 pushes the first blocking component 321 and the second blocking component 322 to move along the circulation channel 11A toward the first cover body 12. At this time, the first through hole 1B is closed and the second through hole 1C is opened. The dehumidification component 2 can be connected to the outside world through the second through hole 1C, thereby discharging the absorbed moisture to the outside world through the second through hole 1C, so that the dehumidification component 2 can absorb moisture again. This can prevent moisture from accumulating and fogging in the space connected to the first through hole 1B, such as the internal space of the lampshade 10.

[0087] In some examples, the number of the first through hole 1B and the number of the second through hole 1C can both be 2. In other examples, the number of the first through hole 1B and the number of the second through hole 1C can both be other numbers, such as 3, 4, 5, etc.

[0088] In other embodiments, the first blocking member 321 can be disposed within the first cover 12. In this case, when the first blocking member 321 opens the first through hole 1B, another first through hole 1B is disposed radially to one side of the first through hole 1B. The dehumidifying element 2 can absorb moisture from a space connected to the first through hole 1B, such as the interior space of the lampshade 10, through the multiple first through holes 1B, thereby increasing the dehumidifying element 2's moisture absorption efficiency. After moisture absorption from the space connected to the first through hole 1B is complete or when the moisture absorbed by the dehumidifying element 2 needs to be removed, the switching assembly 3 is switched to the first state. The second blocking member 322 can also be disposed within the second cover 13. In this case, when the second blocking member 322 opens the second through hole 1C, another second through hole 1C is disposed radially to one side of the second through hole 1C. The dehumidifying element 2 can communicate with the outside world through the multiple second through holes 1C, thereby quickly discharging the absorbed moisture to the outside world through the second through holes 1C, thereby increasing the dehumidifying element 2's moisture removal efficiency.

[0089] In some embodiments, the shell 1 also includes a first breathable membrane 14 and a second breathable membrane 15, the first breathable membrane 14 and the second breathable membrane 15 are connected to the shell 1, and the first breathable membrane 14 covers one end opening of the circulation channel 11A, and the second breathable membrane 15 covers the other end opening of the circulation channel 11A, the first breathable membrane 14, the second breathable membrane 15 and the outer shell 11 define a accommodating cavity 1A; the first cover body 12 and the second cover body 13 are arranged between the first breathable membrane 14 and the second breathable membrane 15.

[0090] In this way, by covering one end opening of the circulation channel 11A with the first breathable membrane 14 and covering the other end opening of the circulation channel 11A with the second breathable membrane 15, the first breathable membrane 14, the second breathable membrane 15 and the outer shell 11 can define an accommodating cavity 1A. The first breathable membrane 14, the second breathable membrane 15 and the outer shell 11 seal the internal space of the lampshade 10 to prevent other substances from entering the internal space of the lampshade 10 and to achieve air circulation.

[0091] In some embodiments, the first blocking member 321 is disposed between the first breathable membrane 14 and the first cover body 12, or the first blocking member 321 is disposed on the side of the first cover body 12 facing away from the first breathable membrane 14; the second blocking member 322 is disposed between the second breathable membrane 15 and the second cover body 13, or the second blocking member 322 is disposed on the side of the second cover body 13 facing away from the second breathable membrane 15.

[0092] In this way, this arrangement can enable the first blocking member 321 to block or open the first through hole 1B of the first cover body 12, and the second blocking member 322 to block or open the second through hole 1C of the second cover body 13. Through the alternating blocking actions of the first blocking member 321 and the second blocking member 322, at least one of the first through hole 1B and the second through hole 1C can be in a blocked state.

[0093] In some examples, the first blocking member 321 is disposed between the first breathable membrane 14 and the first cover body 12, and the second blocking member 322 is disposed between the second breathable membrane 15 and the second cover body 13. The first blocking member 321 can block or open the first through hole 1B of the first cover body 12, and the second blocking member 322 can block or open the second through hole 1C of the second cover body 13. Through the alternating blocking actions of the first blocking member 321 and the second blocking member 322, at least one of the first through hole 1B and the second through hole 1C can be in a blocked state.

[0094] In some examples, the first blocking member 321 is provided on the side of the first cover body 12 facing away from the first breathable membrane 14, and the second blocking member 322 is provided on the side of the second cover body 13 facing away from the second breathable membrane 15. Therefore, the first blocking member 321 can block or open the first through hole 1B of the first cover body 12, and the second blocking member 322 can block or open the second through hole 1C of the second cover body 13. Through the alternating blocking action of the first blocking member 321 and the second blocking member 322, at least one of the first through hole 1B and the second through hole 1C can be in a blocked state.

[0095] In some embodiments, the first cover body 12 covers one end opening of the circulation channel 11A, and the second cover body 13 covers the other end opening of the circulation channel 11A. The first cover body 12, the second cover body 13 and the outer shell 11 define an accommodating cavity 1A; the shell 1 also includes a first breathable membrane 14 and a second breathable membrane 15. The first breathable membrane 14 is arranged on the side of the first cover body 12 facing away from the second cover body 13, and the second breathable membrane 15 is arranged on the side of the second cover body 13 facing away from the first cover body 12.

[0096] In this way, by covering one end opening of the circulation channel 11A with the first cover body 12 and covering the other end opening of the circulation channel 11A with the second cover body 13, the first cover body 12, the second cover body 13 and the outer shell 11 can define a accommodating cavity 1A, and the first breathable membrane 14, the second breathable membrane 15 and the outer shell 11 seal the internal space of the lampshade 10 to prevent other substances from entering the internal space of the lampshade 10.

[0097] In some embodiments, the first blocking member 321 includes a first flexible pad 3211 .

[0098] In this way, the fit between the first flexible pad 3211 and the first through hole 1B is automatically adjusted, thereby enhancing the sealing stability between the first flexible pad 3211 and the first through hole 1B.

[0099] In some examples, the first flexible pad 3211 can be a rubber pad, foam plastic, polyester fiber pad, etc.

[0100] In some embodiments, the first blocking member 321 further includes a first retaining frame 3212 , the first retaining frame 3212 is connected to the output shaft 311 , and the first flexible pad 3211 is connected to a side of the first retaining frame 3212 facing the first cover 12 .

[0101] In this way, by connecting the first retaining frame 3212 to the output shaft 311 and the first flexible pad 3211 to the side of the first retaining frame 3212 facing the first cover body 12, the first retaining frame 3212 can support the first flexible pad 3211 to ensure that the first flexible pad 3211 can better seal the first through hole 1B.

[0102] In some embodiments, the structure of the second blocking member 322 may refer to the structure of the first blocking member 321 , and will not be described in detail again.

[0103] In some embodiments, the driving member 31 also includes an electric power member 312 and an elastic return member 313. The electric power member 312 is connected to the output shaft 311 and is used to drive the output shaft 311 to move so that the switching component 3 switches from the second state to the first state; the elastic return member 313 is used to switch the switching component 3 from the first state to the second state.

[0104] In this way, when the switching component 3 is in the second state, the first through hole 1B is opened and the second through hole 1C is blocked. At this time, the dehumidification device 30 is isolated from the external space of the lampshade 10 and connected to the internal space of the lampshade 10. The dehumidification component 2 can absorb moisture in the internal space of the lampshade 10 through the first through hole 1B to keep the internal space of the lampshade 10 dry and prevent fogging. After the moisture absorption of the interior space of the lampshade 10 is completed or the moisture absorbed by the dehumidifying component 2 needs to be removed, the electric power component 312 drives the output shaft 311 to move, and the output shaft 311 pushes the first blocking component 321 and the second blocking component 322 to move in the direction toward the first cover body 12, switching the switching component 3 to the first state, the first through hole 1B is closed, and the second through hole 1C is opened. The dehumidifying device 30 is connected to the external space of the lampshade 10 and isolated from the interior space of the lampshade 10. The dehumidifying component 2 can discharge the absorbed moisture in the interior space of the lampshade 10 through the second through hole 1C to the outside through the second through hole 1C, so that the dehumidifying component 2 can absorb moisture again, thereby preventing moisture from accumulating in the interior space of the lampshade 10 and causing fogging. After the moisture absorbed by the dehumidifying component 2 is removed, under the action of the elastic reset component 313, the switching component 3 switches from the first state to the second state.

[0105] Normally, the switching component 3 is in the second state, so that the dehumidifying component 2 absorbs moisture. When the moisture in the dehumidifying component 2 needs to be discharged, the switching component 3 is switched to the first state.

[0106] In some embodiments, the dehumidification component 2 is disposed on the electric power component 312 .

[0107] In this way, when it is necessary to discharge moisture from the dehumidifying element 2, the switching assembly 3 is switched to the first state. At this time, the electric power element 312 operates and generates heat. The heat generated by the electric power element 312 heats the dehumidifying element 2, so that the moisture in the dehumidifying element 2 is discharged through the second through hole 1C as quickly as possible, so that the dehumidifying element 2 can be used again. This eliminates the need for a separate device for heating the dehumidifying element 2, saving costs and simplifying the structure.

[0108] In some embodiments, the dehumidification component 2 is arranged around the electric power component 312.

[0109] In this way, the contact area between the dehumidifying element 2 and the electric power element 312 can be increased, thereby increasing the heating effect of the dehumidifying element 2.

[0110] In some embodiments, see Figures 5 to 10 , Figure 10 A schematic structural diagram of another dehumidification device 30 provided in some embodiments of the present application. The dehumidification element 2 includes a moisture-absorbing sheet 21 and / or a reversible desiccant 22. In other words, the dehumidification element 2 may include the moisture-absorbing sheet 21, or the dehumidification element 2 may include the reversible desiccant 22, or the dehumidification element 2 may include the moisture-absorbing sheet 21 and the reversible desiccant 22.

[0111] In this way, the moisture-absorbing sheet 21 can increase the contact area with moisture, and the reversible desiccant 22 can automatically adjust the moisture absorption and release state of the dehumidifying component 2 according to the ambient humidity, thereby improving the dehumidification efficiency of the dehumidifying component 2.

[0112] In some examples, the moisture absorbent sheet 21 may be a thin sheet structure, or the moisture absorbent sheet 21 may be a honeycomb structure.

[0113] In some examples, the reversible desiccant 22 may be a silica gel material, or the reversible desiccant 22 may be a lithium chloride composite material.

[0114] In some embodiments, at least a portion of the output shaft 311 forms the iron core 3111 , that is, the output shaft 311 may include the iron core 3111 , or the output shaft 311 is a separate part, and the iron core 3111 is fixed to the output shaft 311 .

[0115] The electric power unit 312 includes a winding structure 3121, which can be, for example, a coil. The winding structure 3121 surrounds the iron core 3111 and cooperates with the iron core 3111 to drive the output shaft 311 to move circumferentially. For example, the winding structure 3121 and the iron core 3111 form a translational solenoid valve structure. Alternatively, the winding structure 3121 and the iron core 3111 can drive the output shaft 311 to rotate about its axis. For example, the winding structure 3121 and the iron core 3111 form a rotational solenoid valve structure.

[0116] That is to say, the winding structure 3121 can drive the output shaft 311 to move circumferentially of the output shaft 311, or the winding structure 3121 can drive the output shaft 311 to rotate around the axis of the output shaft 311, or the winding structure 3121 can drive the output shaft 311 to move circumferentially and rotate along the axis of the output shaft 311.

[0117] In this way, through the cooperation between the winding structure 3121 and the iron core 3111, the winding structure 3121 drives the output shaft 311 to move along the circumferential direction of the output shaft 311, thereby driving the first sealing member 321 and the second sealing member 322 to move along the circumferential direction of the output shaft 311, or the winding structure 3121 drives the output shaft 311 to rotate around the axis of the output shaft 311, thereby driving the first sealing member 321 and the second sealing member 322 to move along the axis of the output shaft 311, both of which can realize the opening and blocking of the first through hole 1B and the second through hole 1C by the first sealing member 321 and the second sealing member 322.

[0118] Specifically, in some embodiments, when the winding structure 3121 is powered off, the second blocking member 322 is pressed into contact with the second cover 13, and the first flexible pad 3211 in the first blocking member 321 is separated from the first cover 12. At this time, the switching assembly 3 is in the second state, the second blocking member 322 blocks the second through hole 1C in the second cover 13, and the first through hole 1B in the first cover 12 is opened. At this time, the dehumidification device 30 is isolated from the external space of the lampshade 10 and connected to the internal space of the lampshade 10. The dehumidification member 2 can absorb moisture from the internal space of the lampshade 10 through the first through hole 1B to keep the internal space of the lampshade 10 dry and prevent fogging. After the moisture absorption of the internal space of the lampshade 10 is completed or the moisture absorbed by the dehumidification member 2 needs to be removed, the switching assembly 3 is switched to the first state, and the winding structure 3121 is powered on.

[0119] When the winding structure 3121 is energized, a certain magnetic field is generated, driving the iron core 3111 to move axially along the output shaft 311, or circumferentially along the output shaft 311. This application is introduced as an example of an example in which the winding structure 3121 is energized and a certain magnetic field is generated, driving the iron core 3111 to move axially along the output shaft 311.

[0120] Specifically, when the winding structure is energized, a certain magnetic field is generated, driving the iron core 3111 to move axially along the output shaft 311, thereby driving the output shaft 311 to move in the direction of the first blocking member 321 along the flow channel 11A toward the first cover 12. The first flexible pad 3211 in the first blocking member 321 is pressed into contact with the first cover 12, and the second blocking member 322 is separated from the second cover 13. At this time, the switching assembly 3 is in the first state, the first flexible pad 3211 blocks the first through hole 1B in the first cover 12, and the second through hole 1C in the second cover 13 is opened. The dehumidification device 30 is connected to the external space of the lampshade 10 and isolated from the internal space of the lampshade 10. The dehumidification element 2 can discharge the absorbed moisture to the outside through the second through hole 1C, so that the dehumidification element 2 can absorb moisture again, thereby preventing moisture from accumulating in the internal space of the lampshade 10 and causing fogging. In addition, the winding structure 3121 has resistance when energized, converting electrical energy into thermal energy, generating heat. The dehumidifying element 2 is arranged around the winding structure 3121. The heat generated by the winding structure 3121 will bake the dehumidifying element 2, accelerating the volatilization of moisture in the dehumidifying element 2. After the winding structure 3121 is powered for a period of time or the moisture absorbed by the dehumidifying element 2 is eliminated, the switching component 3 is switched to the second state, and the winding structure 3121 is de-energized.

[0121] Exemplarily, the resetting elastic member may be a columnar spring, a conical coil spring, or the like.

[0122] In some embodiments, the housing 1 includes an outer shell 11, a first cover 12, and a second cover 13. The outer shell 11 is provided with a circulation channel 11A. The first cover 12 and the second cover 13 are both connected to the outer shell 11 and are spaced apart along the axial direction of the circulation channel 11A. The first cover 12, the second cover 13, and the outer shell 11 define at least a portion of a receiving cavity. The first through hole 1B is provided in the first cover 12, and the second through hole 1C is provided in the second cover 13.

[0123] Along the axial direction of the circulation channel 11A, the projection of the first through hole 1B is located outside the projection of the second through hole 1C, that is, along the axial direction of the circulation channel 11A, the projection of the first through hole 1B and the projection of the second through hole 1C have no overlapping parts, so that when the switching component 3 is in the first state, the switching component 3 blocks the first through hole 1B and opens the second through hole 1C; when the switching component 3 is in the second state, the switching component 3 opens the first through hole 1B and blocks the second through hole 1C.

[0124] In some embodiments, the electric power component 312 includes a locked-rotor motor 3122 , which is connected to the output shaft 311 to drive the output shaft 311 to rotate.

[0125] In this way, by connecting the locked-rotor motor 3122 to the output shaft 311, the locked-rotor motor 3122 drives the output shaft 311 to rotate, thereby driving the first blocking member 321 and the second blocking member 322 to rotate, so as to realize the opening and blocking of the first through hole 1B and the second through hole 1C by the first blocking member 321 and the second blocking member 322.

[0126] In some embodiments, the electric power component 312 may further include a first support frame 314 . The first support frame 314 is connected to the housing 11 . The electric power component 312 is connected to the first support frame 314 . The first support frame 314 may support the electric power component 312 .

[0127] The first support frame 314 and the moisture-absorbing sheet 21 may be respectively disposed on opposite sides of the electric power component 312 , so as to facilitate the disposition of the first support frame 314 and the moisture-absorbing sheet 21 .

[0128] In this way, by disposing the first support frame 314 between the housing 11 and the electric power component 312 , the first support frame 314 can support the electric power component 312 .

[0129] In some examples, the electric power component 312 can be a locked-rotor motor 3122 .

[0130] In some embodiments, the electric power member 312 may further include a transmission assembly 315 . The transmission assembly 315 is connected between the output shaft 311 and the first blocking member 321 to drive the first blocking member 321 to rotate.

[0131] In this way, by connecting the transmission assembly 315 between the output shaft 311 and the first blocking member 321, the driving force output by the electric power member 312 drives the output shaft 311 to rotate, driving the transmission assembly 315 to transmit, so as to realize the opening and blocking of the first through hole 1B by the first blocking member 321.

[0132] In some examples, the first blocking member 321 may be connected to the second blocking member 322 , so that the rotation of the first blocking member 321 drives the second blocking member 322 to rotate, thereby causing the second blocking member 322 to open or close the second through hole 1C.

[0133] Alternatively, the transmission assembly 315 is also in transmission connection with the second blocking member 322 , so that the output shaft 311 drives the second blocking member 322 to rotate through the transmission assembly 315 , so that the second blocking member 322 opens or closes the second through hole 1C.

[0134] This application uses the example that the first blocking member 321 can be connected to the second blocking member 322 for illustration.

[0135] In some embodiments, the transmission assembly 315 may include a first gear 3151 and a second gear 3152 . The first gear 3151 is connected between the output shaft 311 and the second gear 3152 . The second gear 3152 is connected to the first blocking member 321 to drive the first blocking member 321 to rotate.

[0136] In this way, the driving force output by the stall motor 3122 drives the output shaft 311 to rotate, drives the first gear 3151 in the transmission assembly 315 to rotate, and the first gear 3151 and the second gear 3152 are engaged, driving the second gear 3152 to rotate, thereby driving the first blocking member 321 and the second blocking member 322 to rotate, so as to realize the opening and blocking of the first through hole 1B and the second through hole 1C by the first blocking member 321 and the second blocking member 322.

[0137] Specifically, in some embodiments, when the stalled-rotor motor 3122 is powered off, the second blocking member 322 overlaps with the second through hole 1C in the second cover 13, while the first flexible pad 3211 in the first blocking member 321 does not overlap with the first through hole 1B in the first cover 12. At this time, the switching assembly 3 is in the second state, the second blocking member 322 blocks the second through hole 1C in the second cover 13, and the first through hole 1B in the first cover 12 is open. At this time, the dehumidifier 30 is isolated from the exterior of the lampshade 10 and communicates with the interior of the lampshade 10. The dehumidifier 2 can absorb moisture from the interior of the lampshade 10 through the first through hole 1B to keep the interior of the lampshade 10 dry and prevent fogging. After the moisture absorption from the interior of the lampshade 10 is completed or the moisture absorbed by the dehumidifier 2 needs to be removed, the switching assembly 3 is switched to the first state, and the stalled-rotor motor 3122 is powered on.

[0138] When the locked-rotor motor 3122 is energized, the first blocking member 321 rotates along the flow channel 11A toward the first cover 12. The first flexible pad 3211 in the first blocking member 321 overlaps with the first through hole 1B in the first cover 12, while the second blocking member 322 does not overlap with the second through hole 1C in the second cover 13. At this time, the switching assembly 3 is in the first state, with the first flexible pad 3211 blocking the first through hole 1B in the first cover 12 and the second through hole 1C in the second cover 13 open. The dehumidifier 30 communicates with the exterior of the lampshade 10 and is isolated from the interior of the lampshade 10. The dehumidifier 2 can discharge absorbed moisture to the outside through the second through hole 1C, allowing it to absorb moisture again. This prevents moisture from accumulating within the interior of the lampshade 10 and causing fogging. Furthermore, when the locked-rotor motor 3122 is energized, the electromagnetic coil inside the motor has resistance, which converts electrical energy into heat, generating heat. The dehumidifying element 2 is disposed around the group structure 3121. The heat generated by the electromagnetic coil bakes the dehumidifying element 2, accelerating the volatilization of moisture in the dehumidifying element 2. After the locked-rotor motor 3122 is energized for a period of time or after the moisture absorbed by the dehumidifying element 2 is discharged, the switching assembly 3 is switched to the second state, and the locked-rotor motor 3122 is deenergized.

[0139] Among them, the winding structure 3121 and the locked-rotor motor 3122 will complete the opening and closing of the first through hole 1B and the second through hole 1C at the moment of power-on, so the moisture evaporated by the heating and dehumidifying component 2 will not return to the internal space of the lampshade 10, effectively improving the dehumidification efficiency of the dehumidification device 30.

[0140] In some examples, the elastic return member 313 may be a torsion spring or the like.

[0141] In some embodiments, see Figures 11 to 14 , Figure 11 for Figure 4 The diagram shows the cooperation relationship between the first blocking member and the first cover when the dehumidification device is in the first state. Figure 12 for Figure 4 The diagram shows the cooperation relationship between the second blocking member and the second cover when the dehumidification device is in the first state. Figure 13 for Figure 4 The diagram shows the cooperation relationship between the first blocking member and the first cover when the dehumidification device is in the second state. Figure 14 for Figure 4The diagram shows the mating relationship between the second sealing member and the second cover when the dehumidification device is in the second state. The first sealing member 321 includes a conductive area 323 and a blocking area 324. The conductive area 323 is provided with a first conductive hole 3231. When the switching assembly 3 is in the first state, the blocking area 324 covers the first through hole 1B, and the first conductive hole 3231 is located radially to one side of the first through hole 1B. When the switching assembly 3 is in the second state, the first conductive hole 3231 communicates with the first through hole 1B, and the blocking area 324 is located radially to one side of the first through hole 1B.

[0142] As a result, this arrangement facilitates the blocking and opening of the first through hole 1B. Specifically, when the switching assembly 3 is in the first state, the first flexible pad 3211 in the first blocking member 321 overlaps with the first through hole 1B in the first cover 12, and the blocking area 324 covers the first through hole 1B, blocking the first through hole 1B. At this time, the dehumidification device 30 is connected to the external space of the lampshade 10 and isolated from the internal space of the lampshade 10. When the switching assembly 3 is in the second state, the first flexible pad 3211 in the first blocking member 321 does not overlap with the first through hole 1B in the first cover 12, and the first conductive hole 3231 is connected to the first through hole 1B. At this time, the dehumidification device 30 is connected to the internal space of the lampshade 10.

[0143] In some embodiments, the dehumidification device 30 further includes a first sealing member 8 , which is disposed between the first cover 12 and the outer shell 11 .

[0144] In this way, by arranging the first sealing member between the first cover 12 and the housing 11, the first cover 12 and the housing 11 can be sealed to prevent moisture from entering the lampshade 10 through the gap between the first cover 12 and the housing 11.

[0145] In some embodiments, the dehumidification device 30 further includes a second sealing member 9 , which is disposed between the second cover 13 and the outer shell 11 .

[0146] In this way, by arranging the second sealing member 9 between the second cover 13 and the housing 11 , the second cover 13 and the housing 11 can be sealed to prevent moisture from entering the lampshade 10 through the gap between the second cover 13 and the housing 11 .

[0147] In some embodiments, the structure of the second blocking member 322 and the sealing between the second cover plate can refer to the first blocking member 321 and will not be described in detail again.

[0148] Among them, the second sealing member includes a second flexible pad 3221 and a second retaining frame 3222. The second flexible pad 3221 is connected to the side of the second retaining frame 3222 facing the second cover plate. The second retaining frame 3222 can support the second flexible pad 3221 to ensure that the second flexible pad 3221 can better seal the second through hole 1C.

[0149] See also Figure 15 , Figure 15 The present invention relates to a method for controlling the power on and off of the winding structure 3121 or the locked-rotor motor 3122. First, a humidity sensor is used to detect the humidity of the interior space of the lampshade 10 in real time. The humidity sensor then sends a signal to control the power on and off of the winding structure 3121 or the locked-rotor motor 3122. If the maximum humidity value M of the interior space of the lampshade 10 is greater than or equal to a first set value K, the winding structure 3121 or the locked-rotor motor 3122 is powered on. If the maximum humidity value M of the interior space of the lampshade 10 is less than the first set value K, the humidity sensor again detects the humidity of the interior space of the lampshade 10 in real time. If the minimum humidity value N of the interior space of the lampshade 10 is less than or equal to a second set value L, the winding structure 3121 or the locked-rotor motor 3122 is powered off. If the minimum humidity value N of the interior space of the lampshade 10 is greater than the second set value L, the humidity sensor again detects the humidity of the interior space of the lampshade 10 in real time. The first set value K is the calibrated maximum humidity value of the moisture in the interior space of the lampshade 10, and the second set value L is the calibrated minimum humidity value of the moisture in the interior space of the lampshade 10, wherein the first set value K is greater than the second set value L. The switching component 3 is switched between the first state and the second state by turning on and off the power of the winding structure 3121 or the locked-rotor motor 3122.

[0150] In some embodiments, please refer to Figure 10 The dehumidification device 30 further includes a heating element 4 , which is disposed on the dehumidification element 2 to heat the dehumidification element 2 .

[0151] In this way, the heating element 4 can heat the dehumidifying element 2 to improve the dehumidification efficiency of the dehumidifying element 2.

[0152] In some examples, the heating element 4 can be a heating plate, a heating wire, etc.

[0153] In some embodiments, the dehumidification device 30 further includes a refrigeration component 5 , which is disposed in the dehumidification component 2 to cool the dehumidification component 2 .

[0154] In this way, the refrigeration element 5 can cool the dehumidification element 2 to convert the moisture from gas to liquid, thereby accelerating the dehumidification element 2 to absorb water, thereby improving the dehumidification efficiency of the dehumidification element 2.

[0155] In some examples, the cooling element 5 may be a ceramic cooling plate or the like.

[0156] In some embodiments, the dehumidification device 30 further includes a fan, which is disposed at the second through hole 1C for extracting moisture.

[0157] In this way, the fan can accelerate the dehumidification of the dehumidifying element 2 to improve the dehumidification efficiency of the dehumidifying element 2.

[0158] In some embodiments, the switching assembly 3 includes a first valve 6 and a second valve. The first valve 6 is provided in the first through hole 1B for opening or closing the first through hole 1B. The second valve is provided in the second through hole 1C for opening or closing the second through hole 1C.

[0159] In this way, by arranging the first valve 6 in the first through hole 1B and the second valve in the second through hole 1C, the first valve 6 can open or close the first through hole 1B, and the second valve can open or close the second through hole 1C. This arrangement can realize the switching of the switching component 3 between the first state and the second state.

[0160] In some examples, the first valve 6 and the second valve 7 may be solenoid valves, electric regulating valves, electric ball valves, electric gate valves, etc., which are not specifically limited in this application.
