Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more particularly to a humidification device and a vehicle. Background Technology

[0002] Generally, a passenger cabin temperature maintained between 21°C and 24°C is considered comfortable for passengers at a relative humidity of 40% to 50%. Below this relative humidity, passengers' skin may become dry and itchy, and in severe cases, passengers' mucous membranes and eyes may experience dryness and irritation. Under certain climatic conditions, the humidity in a vehicle's passenger cabin may drop below a percentage point that provides acceptable comfort for vehicle passengers.

[0003] To address this, related technologies have proposed humidification devices for passenger cabins. However, due to gravity, the absorbent sponge in these devices will accumulate water at the bottom and inside of the sponge after a period of use without a water source, leaving the surface and top of the sponge dry. This results in poor humidification after the sponge has been working for an extended period.

[0004] Therefore, there is an urgent need for a humidification device to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a humidification device and vehicle that can guarantee the humidification effect.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, a humidification device is provided, comprising:

[0008] Humidifying core;

[0009] The outer shell has a receiving cavity and a ventilation hole, the ventilation hole communicating with the receiving cavity, and the humidifying inner core disposed within the receiving cavity. The outer shell is provided with a compression structure, the compression structure abutting against the humidifying inner core and capable of compressing the humidifying inner core, and the compression force applied to the humidifying inner core by the compression structure is adjustable.

[0010] As a preferred technical solution of the above-mentioned humidification device, the outer shell includes a first shell and a second shell, the first shell and the second shell are connected to form the receiving cavity, the extrusion structure is disposed on the first shell and / or the second shell, and the first shell and the second shell can move relative to each other to adjust the extrusion force of the extrusion structure to extrude the humidification inner core.

[0011] As a preferred embodiment of the aforementioned humidification device, the first housing and the second housing are threadedly connected; or...

[0012] The first housing and the second housing are capable of linear movement relative to each other.

[0013] As a preferred embodiment of the above-mentioned humidification device, the extrusion structure includes a protrusion disposed on the inner wall of the first housing and / or the inner wall of the second housing, and the protrusion is disposed toward the end face of the humidification core.

[0014] As a preferred embodiment of the humidification device described above, the protrusion is formed by the shell recessing into the end face of the humidification core.

[0015] As a preferred embodiment of the humidification device described above, the outer shell has a water injection hole that communicates with the receiving cavity, and the water injection hole penetrates the protrusion.

[0016] As a preferred embodiment of the humidification device described above, the central axis of the water injection hole, the central axis of the protrusion, and the central axis of the housing coincide.

[0017] As a preferred technical solution of the above-mentioned humidification device, the extrusion structure includes an adjustable extrusion wall, which is the inner side wall of the outer shell facing the end face of the humidification core, or the extrusion side wall is the peripheral wall of the outer shell.

[0018] Secondly, a vehicle is provided, including an air duct and a humidification device as described in any of the above embodiments, wherein the air duct is equipped with the humidification device.

[0019] As a preferred technical solution for the aforementioned vehicle, the outer peripheral wall of the outer shell is provided with a mating part, and the outer shell is detachably connected to the air duct through the mating part.

[0020] The present invention has at least the following beneficial effects:

[0021] The humidification device and vehicle provided by this invention have a housing cavity and ventilation holes in the outer shell, with the ventilation holes communicating with the housing cavity. The humidifying core is disposed within the housing cavity, allowing flowing air to enter the housing cavity through the ventilation holes, flow through the humidifying core, and exit from the ventilation holes, carrying away moisture from the humidifying core and thus humidifying the flowing air to improve the humidity of the passenger cabin. The compression structure can apply force to the humidifying core, and the applied force is adjustable. Compared with the prior art, the compression force applied to the humidifying core is adjustable, so the moisture in the humidifying core is squeezed out and accumulates on the outer surface of the humidifying core under different conditions. The flowing air comes into contact with the water on the outer surface of the humidifying core and is humidified, thus maintaining a good humidification effect even after the humidifying core has been working for a long time. This humidification device can reduce costs and increase efficiency, solve the humidification conditions and humidity requirements of the passenger cabin, and when the humidification device is placed in the air duct, it can utilize the hot air properties of the air duct itself in winter to achieve natural humidification, thus achieving high space utilization.

[0022] In addition, the extrusion structure can limit the humidifying core to a certain extent, preventing it from shaking after being subjected to strong vibration. This not only prevents the water inside the humidifying core from being thrown into the air duct under the action of acceleration during vibration, causing the humidifying core to dehydrate, but also prevents the humidifying core from vibrating and impacting the outer shell, thus avoiding noise.

[0023] Since no additional branch power harness is required, vehicles that have already left the factory can be directly retrofitted with this system. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0032] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0035] like Figure 1-4 As shown, the humidifying device includes an outer shell and a humidifying inner core 1. The outer shell has a receiving cavity and a ventilation hole 31. The ventilation hole 31 communicates with the receiving cavity. The humidifying inner core 1 is disposed in the receiving cavity. Air can pass through the ventilation hole 31 and flow through the humidifying inner core 1 to be humidified. The outer shell is provided with a compression structure. The compression structure abuts against the end face of the humidifying inner core 1 and can compress the humidifying inner core 1. The compression force applied to the humidifying inner core 1 by the compression structure is adjustable.

[0036] Because the outer shell has a receiving cavity and a ventilation hole 31, the ventilation hole 31 is connected to the receiving cavity, and the humidifying inner core 1 is disposed in the receiving cavity, the flowing air can enter the receiving cavity through the ventilation hole 31 and flow through the humidifying inner core 1, and then flow out from the ventilation hole 31 to carry away the water vapor of the humidifying inner core 1, thereby humidifying the flowing air and improving the humidity of the passenger cabin. Compared with the prior art, the humidification device provided by the present invention can humidify the passenger cabin without increasing the wiring harness, reducing the humidification cost and requiring less space. The extrusion structure abuts against the end face of the humidifying inner core 1 and can extrude the humidifying inner core 1. The extrusion pressure applied by the extrusion structure to the humidifying inner core 1 is adjustable. Thus, the humidifying inner core 1 is compressed under the extrusion pressure and its volume is reduced accordingly. The water in the humidifying inner core 1 is squeezed out and accumulates on the outer surface of the humidifying inner core 1. The flowing air comes into contact with the water on the outer surface of the humidifying inner core 1 and is humidified, thereby ensuring a good humidification effect even after the humidifying inner core 1 has been working for a long time.

[0037] This humidification device can reduce costs and increase efficiency, solve the humidification conditions and humidity requirements of the passenger cabin. When the humidification device is installed in the air duct, it can utilize the hot air properties of the air duct 100 to achieve natural humidification, thus achieving high space utilization.

[0038] In some embodiments, such as Figure 2-4 As shown, the outer shell includes a first shell 2 and a second shell 3. The first shell 2 and the second shell 3 are connected to form a receiving cavity. The extrusion structure can be positioned in three ways: one is that the extrusion structure is simultaneously located in the first shell 2 and the second shell 3; the other two are that the extrusion structure is located in either the first shell 2 or the second shell 3. The first shell 2 and the second shell 3 can move relative to each other so that the extrusion structure approaches the humidifying inner core 1 and extrudes the humidifying inner core 1, thereby adjusting the extrusion force on the humidifying inner core 1. The connection between the first shell 2 and the second shell 3 facilitates the overall arrangement and installation of the outer shell, especially in confined spaces, where one of the first shell 2 or the second shell 3 can be installed first, followed by the other. By moving one of the first shell 2 and the second shell 3 (either by rotation or linear translation), the volume of the receiving cavity can be adjusted so that one moves relative to the other to reduce the volume of the receiving cavity, thereby causing the extrusion structure to extrude the humidifying inner core 1, and thus squeezing the water in the middle of the humidifying inner core 1 to the outer surface of the humidifying inner core 1.

[0039] Specifically, the second housing 3 is fixedly connected to the air duct 100, and a portion of the second housing 3 is disposed within the air duct 100. This partial placement within the air duct 100 avoids the problem of inconvenience in disassembling the second housing 3 when it is completely placed within the air duct 100, and also facilitates the installation of the second housing 3. In some embodiments, the second housing 3 is provided with a mating part, through which it is detachably connected to the air duct 100. For example, the second housing 3 is snap-fitted to the air duct 100 or connected by fasteners, facilitating disassembly and replacement in case of overall failure. Of course, in other embodiments, the second housing 3 can be welded to the air duct 100 as a single unit using ultrasonic welding or similar methods, with the first housing 2 and the second housing 3 connected to form the aforementioned receiving cavity for accommodating the humidifying inner core 1.

[0040] When the second housing 3 is fixedly connected to the air duct 100 by snap-fit, the mating part is the snap-fit ​​part, which snaps into the air duct 100, thereby achieving the purpose of quick connection with the air duct 100.

[0041] Specifically, the snap-fit ​​part includes a boss 33 and a snap-fit ​​member 34. Both the boss 33 and the snap-fit ​​member 34 are provided on the circumferential sidewall of the second housing 3. The sidewall of the boss 33 facing the snap-fit ​​member 34 abuts against the air duct 100. That is, the diameter of the boss 33 is larger than the diameter of the mounting hole of the air duct 100. This can prevent the second housing 3 from completely entering the air duct 100 and achieve the function of limiting the second housing 3. At least two snap-fit ​​members 34 are provided on the circumferential sidewall of the second housing 3. The snap-fit ​​members 34 and the boss 33 are spaced apart along the axial direction of the second housing 3 to form a snap-fit ​​groove for snapping with the air duct 100. The sidewall of the air duct 100 is limited within the snap-fit ​​groove, thereby achieving the fixation of the second housing 3. In some embodiments, the distance between the snap-fit ​​member 34 and the boss 33 along the axial direction of the second housing 2 is greater than the wall thickness of the air duct 100, but the two should be approximately the same in order to minimize the gap between the air duct 100 and the snap-fit ​​member 34 as much as possible. This can prevent the second housing 3 from colliding with the air duct 100 after violent shaking, thus avoiding noise.

[0042] In some embodiments, the number of snap-fit ​​members 34 is not less than two, and at least two snap-fit ​​members 34 are equally spaced along the circumferential sidewall of the second housing 3, that is, the snap-fit ​​members 34 are evenly arranged along the circumference of the second housing 3, which can improve the stability of the connection between the second housing 3 and the air duct 100. For example, the second housing 3 is provided with four snap-fit ​​members 34.

[0043] In some embodiments, the snap-fit ​​member 34 has a guide slope extending from the boss 33 toward the ventilation hole 31, gradually approaching the central axis of the second housing 3. The guide slope facilitates the snap-fit ​​member 34's entry into the air duct 100. Furthermore, one end of the guide slope near the ventilation hole 31 is smoothly connected to the circumferential sidewall of the second housing 3 to prevent the connection from affecting the assembly between the second housing 3 and the air duct 100.

[0044] Within the air duct 100, the flowing air is divided into at least three streams. Two streams flow past the sides of the outer casing, while the third stream flows inside the casing and comes into contact with the humidifying core 1. These streams then converge into a single stream. Although one stream of air contacts the humidifying core 1, due to the limited space within the outer casing, the total amount of air entering the casing is far less than the amount flowing out of the air outlet of the air duct 100. To increase the total amount of air entering the casing to regulate humidification, the length of the ventilation hole 31 not directly opposite the latch 34 is greater than the length of the ventilation hole 31 directly opposite the latch 34. This increases the total amount of air entering the casing without interfering with the latch 34, thereby increasing the humidity in the passenger cabin.

[0045] In some embodiments, the first housing 2 and the second housing 3 are detachably connected. This allows for quick disassembly and inspection of the first housing 2 and the second housing 3 in case of a malfunction, and rapid replacement of the faulty component with a replacement part. Furthermore, the detachable connection of the first housing 2 and the second housing 3 facilitates cleaning of both housings, preventing mold growth on the humidifying core 1, the first housing 2, and the second housing 3 during humid summer months. It also facilitates the replacement of the humidifying core 1. For example, when the first housing 2 and the second housing 3 are detachably connected, they can be threaded together. More specifically, the first housing 2 has external threads, and the second housing 3 has internal threads. The first housing 2 extends into the second housing 3, and the two are threadedly connected through the internal and external threads.

[0046] Specifically, the extrusion structure includes a deformable extrusion sidewall, which is the inner sidewall of the outer shell facing the end face of the humidifying inner core 1, or the deformable extrusion sidewall is the peripheral wall of the outer shell. As long as the humidifying inner core 1 can be extruded by the outer shell, the humidifying inner core 1 can be extruded, thereby compressing the water in the humidifying inner core 1 to the outer surface of the humidifying inner core 1.

[0047] The deformable extrusion sidewall is made of silicone material. Silicone has good deformability. The purpose of extruding the humidification core can be achieved by extruding the peripheral wall of the outer shell or the sidewall facing the end face of the humidification core 1. After being extruded, some water seeps out and adheres to the outer surface of the humidification core 1, thus achieving the humidification of the air.

[0048] Furthermore, since the first housing 2 and the second housing 3 are threadedly connected, rotating the first housing 2 or the second housing 3 can also achieve relative movement between the first housing 2 and the second housing 3. Under the action of the first housing 2 or the second housing 3, the extrusion structure moves towards the humidifying inner core 1 to apply extrusion force to the humidifying inner core. As the extrusion structure gradually approaches the humidifying inner core 1, the extrusion force applied to the humidifying inner core 1 by the extrusion structure gradually increases. When the second housing 3 moves away from the first housing 2, the extrusion force applied to the humidifying inner core 1 by the extrusion structure gradually decreases.

[0049] Of course, in some other embodiments, the first housing 2 and the second housing 3 can move in a straight line relative to each other. For example, the first housing 2 and the second housing 3 are in a transition fit. This ensures that while the first housing 2 and the second housing 3 move relative to each other, they remain relatively stationary without the action of external force, thus ensuring that the humidifying inner core 1 is not deformed by compression.

[0050] In some embodiments, the extrusion structure includes a protrusion 21 disposed toward the end face of the humidifying core 1. Specifically, the protrusion 21 is disposed on the inner wall of the first housing 2 and / or the inner wall of the second housing 3. The protrusion 21 can extrude force onto the humidifying core 1 when the first housing 2 or the second housing 3 moves, preventing the humidifying core 1 from being too small for the inner wall of the first housing 2 to contact. Furthermore, the protrusion 21 can concentrate the force on the end face of the humidifying core 1, achieving a good extrusion effect. More specifically, the central axis of the protrusion 21 coincides with the central axis of the first housing 2 and / or the second housing 3.

[0051] In some embodiments, the protrusion 21 is formed by the housing recessed into the end face of the humidifying inner core 1. This arrangement enables a lightweight design of the housing and reduces the weight of the housing after the protrusion 21 is additionally provided.

[0052] After repeated contact with flowing air, the moisture in the humidifying core 1 is carried away by the airflow, reducing its humidification effect. Therefore, in some embodiments, the outer shell is provided with a water inlet 211, which communicates with the receiving cavity. Water enters the receiving cavity through the water inlet 211 and is absorbed by the humidifying core 1. This humidifies the air passing over the surface of the humidifying core 1, thereby humidifying the passenger cabin. When humidification of the passenger cabin is not required in certain seasons, water does not need to be added to the humidifying core 1. Even if flowing air enters the shell, the humidifying core 1 remains dry and will not humidify the flowing air.

[0053] Specifically, a water inlet 211 is located on and penetrates the protrusion 21. The water inlet 211 is a stepped hole, with the larger end of the stepped hole away from the humidifying inner core 1. This forms a water tank at the larger end of the stepped hole, which can accumulate a certain amount of water and allow the water to permeate into the humidifying inner core 1 from the smaller end of the stepped hole. The central axis of the water inlet 211, the central axis of the protrusion 21, and the central axis of the shell coincide, so that the humidifying inner core 1 can be evenly moistened when water is injected, thus improving the humidification effect.

[0054] Specifically, the humidifying core 1 is made of a hydrophilic material such as absorbent cotton, so that the humidifying core 1 can store water and prevent water from flowing out of the humidifying core 1 too quickly.

[0055] In order to facilitate the compression of the humidifying core 1 by the protrusion 21 and prevent water from dripping from the humidifying core 1 after compression, in some embodiments the protrusion 21 is provided on the first housing 2. In this way, the first housing 2 compresses the humidifying core 1 from the top. Compared with the protrusion 21 being provided on the second housing 3, it can prevent water from dripping from the top due to gravity after compression. In addition, since the second housing 3 extends into the air duct 100, providing the protrusion 21 on the first housing 2 can also facilitate the movement of the housing.

[0056] In addition, the protrusion 21 can also limit the humidifying core 1 to a certain extent, preventing the humidifying core 1 from shaking after being subjected to strong vibration. This not only prevents the water in the humidifying core 1 from being thrown into the air duct 100 under the action of acceleration during vibration, causing the humidifying core 1 to dehydrate, but also prevents the humidifying core 1 from vibrating and impacting the outer shell, thus generating noise.

[0057] In some embodiments, due to gravity, water tends to accumulate at the bottom of the humidifying core 1. If the vent 31 extends all the way to and through the bottom wall 32 of the receiving cavity, some water will drip into the air duct 100, resulting in faster water consumption, shorter water filling intervals, and more frequent water filling. Therefore, in some embodiments, the bottom of the vent 31 is higher than the bottom wall 32 of the receiving cavity, i.e., the area enclosed by the bottom of the outer casing (the bottom of the receiving cavity) can prevent water from dripping. In addition, when installed horizontally or at an angle in the air duct 100, the arrangement of the vent 31 in the outer casing can be adaptively adjusted to prevent water from dripping from the vent 31 due to gravity.

[0058] In some embodiments, such as Figure 3As shown, the outer casing is equipped with an adjustment structure for adjusting the opening of the ventilation hole 31. This adjustment structure allows for the adjustment of the humidity of the humidified air as needed, to meet the different humidity requirements of different users in different seasons. Specifically, the adjustment structure includes a shielding part disposed in the first housing 2, and the ventilation hole 31 disposed in the second housing 3. A portion of the first housing 2 extends into the second housing 3. By moving the first housing 2 or the second housing 3, the shielding part can move relative to the ventilation hole 31. This allows the shielding part to adjust the ventilation area of ​​the ventilation hole 31. The movement can be rotational or linear, thus achieving the purpose of humidity adjustment.

[0059] For example, the first housing 2 and the second housing 3 are threaded together. The outer peripheral wall of the first housing 2 is provided with an adjusting vent 22. At least a portion of the peripheral wall of the first housing 2 forms a shielding part. The bottom end of the adjusting vent 22 is lower than the top end of the ventilation hole 31, and the bottom end of the shielding part is lower than the bottom end of the ventilation hole 31. By rotating the first housing 2 or the second housing 3, the shielding part can rotate relative to the ventilation hole 31. This allows for adjustment of the flow area of ​​the ventilation hole 31 by the shielding part, and the flow area of ​​the ventilation hole can be adapted according to actual needs. Thus, humidity can be adjusted by screwing on the first housing 2 or the second housing 3, and the screwing angle can be precisely adjusted according to the user's humidity requirements.

[0060] Of course, in some other embodiments, the first housing 2 and the second housing 3 can move linearly relative to each other. Along the axial direction of the outer shell, by pushing or pulling the first housing 2 or the second housing 3, the adjusting vent 22 can move linearly relative to the shielding part, thereby changing the flow area of ​​the ventilation hole 31. After the adjusting vent 22 is disconnected from the ventilation hole 31, the first housing 2 is blocked from the ventilation hole 31. In this way, the purpose of humidity regulation can be achieved by pushing or pulling the first housing 2 or the second housing 3. By controlling the amount of pushing or pulling the first housing 2 or the second housing 3, the communication area between the ventilation hole 31 and the adjusting vent 22 can be adjusted, thereby meeting the humidity needs of different users. For example, the first housing 2 and the second housing 3 are transitionally fitted to enable the first housing 2 and the second housing 3 to move linearly.

[0061] For example, the ventilation hole 31 and the regulating hole 22 are circular or elongated. Of course, in other embodiments, they can also be triangular or polygonal, or irregular shapes, as long as the regulating hole 22 and the ventilation hole 31 are connected to allow the flowing air to enter the receiving cavity formed by the outer shell and to block the ventilation hole 31.

[0062] When the ventilation hole 31 is an elongated hole, such as Figure 1 and Figure 2As shown, ventilation holes 31 are disposed on the circumferential sidewall of the second housing 3. There are multiple ventilation holes 31 arranged circumferentially around the second housing 3, specifically evenly distributed circumferentially. The length of the ventilation holes 31 extends axially along the second housing 3, thus increasing the amount of air flowing into the housing and improving the total amount of air humidified by the humidifying core 3, resulting in a good humidification effect. A blocking part can be used to adjust the flow area of ​​one or more ventilation holes 31. For example, the blocking part can simultaneously block multiple ventilation holes 31 and gradually release the flow area of ​​multiple ventilation holes. For instance, one blocking part is used to adjust the flow area of ​​one ventilation hole 31. As the first housing 2 or the second housing 3 moves, the blocking part can gradually adjust the flow area of ​​the ventilation holes 31. For example, when the first housing 2 rotates relative to the second housing 3, the blocking part releases or blocks the ventilation holes 31 one by one; when the first housing 2 moves relative to the second housing 3, the flow area of ​​multiple ventilation holes 31 is adjusted simultaneously, thereby achieving adjustment of different humidification amounts.

[0063] When the first housing 2 and the second housing 3 are rotated, the number of shielding parts and the number of regulating vents 22 can be the same, and the regulating vents 22 provided on the first housing 2 are spaced apart. However, when the first housing 2 and the second housing 3 move in a straight line relative to each other, the first housing 2 may not be provided with regulating vents 22, and the circumferential sidewall of the first housing 2 becomes the shielding part, so as to adjust the flow area of ​​the ventilation hole 31.

[0064] In some other embodiments, the adjusting structure may also include a sealing plate that selectively blocks the ventilation hole 31. The sealing plate can block the area of ​​the ventilation hole 31 according to actual needs, thereby adjusting the opening degree of the ventilation hole 31. For example, the sealing plate is a ring-shaped structure, fitted onto the second housing 3. The sealing plate is made of silicone, and the ventilation hole 31 is located in the second housing 3. The bottom end of the first housing 2 is higher than the top end of the ventilation hole 31. The sealing plate may be provided with an adjusting air hole 22, which can be moved to communicate with the ventilation hole 31. By moving the sealing plate, the flow area of ​​the ventilation hole 31 can be adjusted. The movement can be rotation. Of course, the sealing plate may also not be provided with an adjusting air hole 22, in which case the movement is translation.

[0065] In some embodiments, a plurality of ventilation holes 31 are spaced apart circumferentially along the second housing 3, and a plurality of regulating air holes 22 are spaced apart circumferentially along the first housing 2. The plurality of ventilation holes 31 and the plurality of regulating air holes 22 are arranged in a one-to-one correspondence, which ensures that a large amount of air enters the receiving cavity and is humidified by the humidifying inner core 1, and ensures that the humidified air can flow out smoothly. Among them, a portion of the ventilation holes 31 serves as an air outlet, while another portion of the ventilation holes 31 serves as an air inlet.

[0066] In addition, the bottom of the ventilation hole 31 is higher than the bottom wall of the receiving cavity, so that the bottom of the receiving cavity can hold water. Under the action of gravity, the water gathers at the bottom of the second shell 3, that is, the bottom of the receiving cavity, which can prevent water from dripping under the action of gravity.

[0067] Since part of the first housing 2 extends into the second housing 3, when water flows from the first housing 2 to the second housing 3, the extension of the first housing 2 into the second housing 3 will guide the water, so that when the water passes between the first housing 2 and the boss 33, it is guided into the area enclosed by the second housing 3 and does not flow out. This can isolate and guide the water, thus achieving a sealing effect.

[0068] Furthermore, since the humidification device provided by this invention does not require additional branch power wiring harnesses, it can be directly installed and used in vehicles that have already left the factory.

[0069] Continue to refer to Figure 4 In an embodiment of the present invention, a vehicle is also provided, which includes an air duct 100 and a humidification device provided in the embodiment of the present invention. The vehicle also includes an air outlet grille. The air duct 100 and / or the air outlet grille are equipped with the humidification device. The air duct 100 has an air outlet, and the air outlet grille is installed at the air outlet. The humidification device may be at least partially disposed inside the air duct 100 or disposed outside the air duct 100, specifically hooked at the air outlet grille.

[0070] The air duct 100 also has a mounting hole located upstream of the air outlet, and the mounting hole is used to install the humidification device provided in the above embodiment. The mating part is specifically a snap-fit ​​part that mates with the mounting hole. In this way, the flowing air first passes through and is then humidified before flowing out through the air outlet. The outflowing air is relatively humid, meeting the humidification requirements of the passenger cabin.

[0071] Specifically, the snap-fit ​​portion includes a boss 33 and a snap-fit ​​member 34. Both the boss 33 and the snap-fit ​​member 34 are disposed on the circumferential sidewall of the second housing 3. The sidewall of the boss 33 facing the snap-fit ​​member 34 abuts against the air duct 100, thereby limiting the second housing 3. At least two snap-fit ​​members 34 are provided on the circumferential sidewall of the second housing 3. The snap-fit ​​members 34 and the boss 33 are spaced apart along the axial direction of the second housing 3 to form a snap-fit ​​groove for engaging with the air duct 100. After the snap-fit ​​member 34 passes through the mounting hole, since the diameter of the boss 33 is larger than the diameter of the mounting hole, the air duct 100 is confined within the snap-fit ​​groove, thereby fixing the second housing 3. In some embodiments, the height of the snap-fit ​​groove is greater than the wall thickness of the air duct 100, but the two should be approximately the same to minimize the gap between the air duct 100 and the snap-fit ​​member 34. This can prevent the second housing 3 from colliding with the air duct 100 and generating noise after violent shaking.

[0072] Since the vehicle of this embodiment includes the humidification device described above, it has all the advantages and beneficial effects of the above embodiments, which will not be repeated here.

[0073] To facilitate installation, in some embodiments, the air duct 100 is a foot-blowing air duct. The humidifier, when installed in the foot-blowing air duct, is less likely to be noticed by passengers in the passenger cabin, thus improving aesthetics.

[0074] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
