Abstract
Description
Technical Field
[0001] This invention relates to the field of vehicle technology, and more particularly to a humidification device, an air duct assembly, 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] In related technologies, car humidifiers can usually only be turned on or off, and the opening degree cannot be adjusted according to the user's needs. Therefore, related technologies adjust the humidity in the car by controlling the amount of water atomization. However, users have different needs, so the adjusted humidity in the car cannot meet the needs of different users.
[0004] Therefore, there is an urgent need for a humidification device to solve the above-mentioned technical problems. Summary of the Invention

[0015] As a preferred embodiment of the humidification device, a plurality of ventilation holes are arranged at intervals along the circumference of the second housing, and the shielding part is arranged in a one-to-one correspondence with the ventilation holes.
[0016] As a preferred embodiment of the humidification device described above, the first housing portion extends into the second housing.
[0017] As a preferred embodiment of the above-mentioned humidification device, the outer shell has a water injection hole, which communicates with the receiving cavity; and / or,
[0018] The humidifying core includes absorbent cotton.
[0019] As a preferred embodiment of the humidification device described above, the outer peripheral wall of the housing is provided with a mating part, which is used to connect with the component to be installed.

[0021] As a preferred technical solution of the above-mentioned humidification device, the snap-fit part includes a boss and a snap-fit member.

[0024] Thirdly, the present invention provides a vehicle including the aforementioned air duct assembly.
[0025] The present invention has at least the following beneficial effects:
[0026] The humidification device, air duct assembly, 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. This allows 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 first and second housings can rotate relative to each other, allowing the adjustment structure to adjust the opening of the ventilation holes.

[0027] 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

[0034] 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.
[0035] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0036] 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.

[0037] 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.
[0038] like Figure 1 and Figure 2 As shown, the humidifier includes an outer shell and a humidifying core 3. The outer shell has a receiving cavity and a ventilation hole 21, which communicates with the receiving cavity. The outer shell is provided with an adjustment structure for adjusting the opening of the ventilation hole 21. The outer shell includes a first housing 1 and a second housing 2, which are detachably connected and can move relative to each other to allow the adjustment structure to adjust the opening of the ventilation hole 21. The humidifying core 3 is disposed in the receiving cavity, and air can pass through the ventilation hole 21 and flow through the humidifying core 3.
[0039] Because the outer shell has a receiving cavity and a ventilation hole 21, with the ventilation hole 21 communicating with the receiving cavity, and the humidifying inner core 3 disposed within the receiving cavity, the flowing air can enter the receiving cavity through the ventilation hole 21, flow through the humidifying inner core 3, and exit from the ventilation hole 21, thus carrying away the moisture in the humidifying inner core 3 and humidifying the flowing air to improve the humidity of the passenger cabin. The first housing 1 and the second housing 2 can rotate relative to each other, allowing the adjustment structure to adjust the opening of the ventilation hole 21. This adjusts the airflow entering the receiving cavity, thereby adjusting the amount of air being humidified as needed, and consequently, adjusting the humidity of the air downstream of the humidifying device. Compared to the prior art, the humidifying device provided by the embodiments of the present invention can adjust the airflow in contact with the humidifying inner core 3 by adjusting the opening of the ventilation hole 21, thereby achieving the purpose of humidity regulation. Furthermore, the humidifying device can humidify the passenger cabin without increasing the wiring harness, reducing humidification costs and requiring less space. This humidification device reduces costs and increases efficiency, addressing the humidification needs and requirements of the passenger cabin. When installed within the air duct, it utilizes the duct's own warm air properties in winter for natural humidification, resulting in high space utilization. Since no additional branch power wiring harness is required, it can be directly installed and used in vehicles already manufactured.
[0040] After repeated contact with flowing air, the moisture in the humidifying core 3 will be carried away by the air, reducing its humidification effect. Therefore, in some embodiments, the outer shell is provided with a water inlet 121, which communicates with the receiving cavity. Water enters the receiving cavity through the water inlet 121 and is absorbed by the humidifying core 3, ensuring sufficient moisture in the humidifying core 3. Air passing over the surface of the humidifying core 3 is then humidified before flowing into the passenger compartment, thus humidifying the passenger compartment. When humidification of the passenger compartment is not required in certain seasons, water does not need to be added to the humidifying core 3. Even if flowing air enters the shell, the humidifying core 3 remains dry and will not humidify the flowing air.
[0041] Specifically, the humidifying core 3 includes a hydrophilic material such as absorbent cotton, so that the humidifying core 3 can store water and prevent water from flowing out of the humidifying core 3 too quickly.
[0042] In some embodiments, due to gravity, water tends to accumulate at the bottom of the humidifying core 3. If the vent 21 extends all the way to and through the bottom wall 24 of the receiving cavity, some water will drip into the air duct, resulting in faster water consumption, shorter water filling intervals, and more frequent water filling. Therefore, in some embodiments, the bottom of the vent 21 is higher than the bottom wall 24 of the receiving cavity, meaning that the area enclosed by the bottom of the outer casing (the bottom of the receiving cavity) can prevent water from dripping. Furthermore, when the humidifying device is installed horizontally or at an angle in the air duct, the arrangement of the vent 21 in the outer casing can be adjusted adaptively to prevent water from dripping from the vent 21 due to gravity.
[0043] In some embodiments, continue to refer to Figure 2 The outer shell includes a first shell 1 and a second shell 2, which are connected to form a receiving cavity. The connection between the first shell 1 and the second shell 2 facilitates the overall arrangement and installation of the outer shell, especially in confined spaces, where one of the first shell 1 or the second shell 2 can be installed first and then the other can be installed.
[0044] Specifically, the second housing 2 is fixedly connected to the air duct, and a portion of the second housing 2 is disposed within the air duct. This partial placement within the air duct avoids the problem of inconvenience in disassembling the second housing 2 when it is completely placed within the air duct, and also facilitates the installation of the second housing 2. In some embodiments, the second housing 2 is provided with a mating part, through which it is detachably connected to the air duct. For example, the second housing 2 is snapped into the air duct or connected by fasteners, facilitating disassembly and replacement of the humidifier in case of overall failure. Of course, in other embodiments, the second housing 2 can be welded to the air duct as a single unit using ultrasonic welding or similar methods, with the first housing 1 and the second housing 2 connected to form the aforementioned receiving cavity for accommodating the humidifier core 3.
[0045] When the second housing 2 is fixedly connected to the air duct by a snap-fit connection, the mating part is a snap-fit part, which snaps into the air duct, thereby achieving the purpose of quick connection with the air duct.
[0046] Specifically, the snap-fit portion includes a boss 22 and a snap-fit member 23. Both the boss 22 and the snap-fit member 23 are disposed on the circumferential sidewall of the second housing 2. The sidewall of the boss 22 facing the snap-fit member 23 abuts against the air duct, that is, the diameter of the boss 22 is larger than the diameter of the mounting hole of the air duct. This prevents the second housing 2 from completely entering the air duct, thus limiting the second housing 2. At least two snap-fit members 23 are provided on the circumferential sidewall of the second housing 2. The snap-fit members 23 and the boss 22 are spaced apart along the axial direction of the second housing 2 to form a snap-fit groove for engaging with the air duct. The sidewall of the air duct is confined within the snap-fit groove, thereby fixing the second housing 2. In some embodiments, the distance between the snap-fit member 23 and the boss 22 along the axial direction of the second housing 2 is greater than the wall thickness of the air duct, but the two should be approximately the same to minimize the gap between the air duct and the snap-fit member 23. This can prevent the second housing 2 from colliding with the air duct and generating noise after violent shaking.
[0047] In some embodiments, at least two snap-fit members 23 are equally spaced along the circumferential sidewalls of the second housing 2, that is, the snap-fit members 23 are uniformly arranged circumferentially along the second housing 2, which can improve the stability of the connection between the second housing 2 and the air duct. For example, the second housing 2 is provided with four snap-fit members 23.
[0048] In some embodiments, the snap-fit member 23 has a guide slope extending from the boss 22 toward the ventilation hole 21, gradually approaching the central axis of the second housing 2. The guide slope facilitates the snap-fit member 23's entry into the air duct. Furthermore, one end of the guide slope near the ventilation hole 21 is smoothly connected to the circumferential sidewall of the second housing 2 to prevent the connection from affecting the assembly of the second housing 2 and the air duct.
[0049] Within the air duct, 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 3. They then converge into a single stream. Although one stream of air contacts the humidifying core 3, due to the limited space within the outer casing, the total amount of air entering the casing is far less than the airflow exiting the air duct. To increase the total amount of air entering the casing to regulate humidification, the length of the ventilation hole 21 not directly opposite the latch 23 is greater than the length of the ventilation hole 21 directly opposite the latch 23. This increases the total amount of air entering the casing without interfering with the latch 23, thereby increasing the humidity in the passenger cabin.
[0050] In some embodiments, the first housing 1 and the second housing 2 are detachably connected. This allows for quick disassembly and inspection of the first housing 1 and the second housing 2 in case of a humidifier malfunction, and quick replacement of the faulty component with a replacement part. Furthermore, the detachable connection of the first housing 1 and the second housing 2 facilitates cleaning of both housings, preventing mold growth on the humidifier core 3, the first housing 1, and the second housing 2 during humid summer months. It also facilitates the replacement of the humidifier core 3. For example, when the first housing 1 and the second housing 2 are detachably connected, they can be threaded together. More specifically, the first housing 1 has external threads, and the second housing 2 has internal threads. The first housing 1 extends into the second housing 2, and the two are threadedly connected through the internal and external threads.
[0051] The first housing 1 and the second housing 2 can move relative to each other so that the opening of the ventilation hole 21 can be adjusted by the adjustment structure.
[0052] In some embodiments, the adjustment structure includes a shielding part 13 disposed on the first housing 1 and a ventilation hole 21 disposed on the second housing 2. Moving the first housing 1 or the second housing 2 can achieve the purpose of adjusting the flow area of the ventilation hole 21 by the shielding part 13.
[0053] For example, the first housing 1 and the second housing 2 are threaded together. An adjustment hole 11 is provided on the outer peripheral wall of the first housing 1, thus forming a shielding portion 13 on at least a portion of the peripheral wall of the first housing 1. The bottom end of the adjustment hole 11 is lower than the top end of the ventilation hole 21, and the bottom end of the shielding portion 13 is lower than the bottom end of the ventilation hole 21. By rotating the first housing 1 or the second housing 2, the shielding portion 13 can rotate relative to the ventilation hole 21, thereby adjusting the flow area of the ventilation hole 21. The flow area of the ventilation hole can be adapted to actual needs. In this way, humidity can be adjusted by screwing on the first housing 1 or the second housing 2, and the screwing angle can be precisely adjusted according to the user's humidity requirements.
[0054] Of course, in some other embodiments, the first housing 1 and the second housing 2 can move linearly relative to each other. Along the axial direction of the outer shell, by pushing or pulling the first housing 1 or the second housing 2, the adjusting hole 11 can move linearly relative to the blocking part 13, thereby changing the flow area of the ventilation hole 21. After the adjusting hole 11 is disconnected from the ventilation hole 21, the first housing 1 and the ventilation hole 21 are blocked. In this way, the purpose of humidity regulation can be achieved by pushing or pulling the first housing 1 or the second housing 2. By controlling the amount of pushing or pulling the first housing 1 or the second housing 2, the communication area between the ventilation hole 21 and the adjusting hole 11 can be adjusted, thereby meeting the humidity needs of different users. For example, the first housing 1 and the second housing 2 are transitionally fitted to enable the first housing 1 and the second housing 2 to move linearly.
[0055] For example, the ventilation hole 21 and the adjustment hole 11 are circular or elongated. Of course, in other embodiments, they can also be triangular or polygonal, or irregular shapes, as long as the adjustment hole 11 and the ventilation hole 21 are connected to allow the flowing air to enter the receiving cavity formed by the outer shell and to block the ventilation hole 21.
[0056] When the ventilation hole 21 is an elongated hole, such as Figure 1 and Figure 2As shown, ventilation holes 21 are provided on the circumferential sidewall of the second housing 2. There are multiple ventilation holes 21, and the multiple ventilation holes 21 are arranged circumferentially along the second housing 2. Specifically, they can be evenly arranged circumferentially. The length direction of the ventilation holes 21 extends along the axial direction of the second housing 2. In this way, the amount of air flowing into the outer shell increases, which can increase the total amount of air humidified by the humidifying inner core 3 and achieve a good humidification effect. The blocking part 13 can be used to adjust the flow area of one or more ventilation holes 21. For example, the blocking part 13 can block multiple ventilation holes 21 at the same time and gradually release the flow area of multiple ventilation holes 21. For example, one blocking part 13 is used to adjust the flow area of one ventilation hole 21, that is, the blocking part 13 and the ventilation hole 21 are arranged in a one-to-one correspondence. As the first housing 1 or the second housing 2 moves, the blocking part 13 can gradually adjust the flow area of the ventilation hole 21. For example, when the first housing 1 rotates relative to the second housing 2, the blocking part 13 releases or blocks the ventilation holes 21 one by one to adjust them; when the first housing 1 moves relative to the second housing 2, the flow area of multiple ventilation holes 21 is adjusted at the same time, thereby realizing the adjustment of different humidification amounts.
[0057] When the first housing 1 and the second housing 2 are rotated, the number of shielding parts 13 and the number of adjusting holes 11 can be the same, and the adjusting holes 11 provided on the first housing 1 are spaced apart. However, when the first housing 1 and the second housing 2 move in a straight line relative to each other, the first housing 1 may not be provided with adjusting holes 11, and the circumferential sidewall of the first housing 1 becomes the shielding part 13, so as to adjust the flow area of the ventilation hole 21.
[0058] In some other embodiments, the adjustment structure may also include a sealing plate that selectively blocks the ventilation hole 21. The sealing plate can block the area of the ventilation hole 21 according to actual needs, thereby adjusting the opening degree of the ventilation hole 21. For example, the sealing plate is a ring-shaped structure, fitted onto the second housing 2. The sealing plate is made of silicone, and the ventilation hole 21 is located in the second housing 2. The bottom end of the first housing 1 is higher than the top end of the ventilation hole 21. The sealing plate may be provided with an adjustment hole 11, which can be moved to communicate with the ventilation hole 21. By moving the sealing plate, the flow area of the ventilation hole 21 can be adjusted. The movement can be rotation. Of course, the sealing plate may also not be provided with an adjustment hole 11, in which case the movement is translation.
[0059] In some embodiments, a plurality of ventilation holes 21 are spaced apart circumferentially along the second housing 2, and a plurality of adjustment holes 11 are spaced apart circumferentially along the first housing 1. The plurality of ventilation holes 21 and the plurality of adjustment holes 11 are arranged in a one-to-one correspondence. This ensures that a large amount of airflow enters the receiving cavity and is humidified by the humidifying core 3, and ensures that the humidified airflow can flow out smoothly. Among them, a portion of the ventilation holes 21 serves as an air outlet, while another portion of the ventilation holes 21 serves as an air inlet.
[0060] In addition, the bottom of the ventilation hole 21 is higher than the bottom wall 24 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 2, that is, the bottom of the receiving cavity, which can prevent water from dripping under the action of gravity.
[0061] Regardless of how the first housing 1 and the second housing 2 are connected, water may leak out from the joint when it flows through them. Therefore, in some embodiments, a portion of the first housing 1 extends into the second housing 2. When water flows from the first housing 1 to the second housing 2, the portion of the first housing 1 extending into the second housing 2 can isolate and guide the water, preventing water from leaking out from the joint between the first housing 1 and the second housing 2, thus achieving a sealing effect.
[0062] Since the humidifying core 3 is disposed within the receiving cavity, if the space of the receiving cavity is too large, it may vibrate after being subjected to severe bumps, causing the humidifying core 3 to shift in position and generate noise. Therefore, in some embodiments, such as Figure 2 As shown, the first housing 1 is provided with a limiting part 12, which abuts against the humidifying inner core 3. The limiting part 12 can limit the humidifying inner core 3 to a certain extent, preventing it from shaking after being subjected to strong vibrations. This not only prevents the water inside the humidifying inner core 3 from being thrown into the air duct under the action of acceleration during vibration, causing the humidifying inner core 3 to dehydrate, but also prevents the humidifying inner core 3 from vibrating and impacting the outer shell, thus avoiding noise. In addition, the first housing 1 can move relative to the second housing 2 to adjust the squeezing force applied to the humidifying inner core 3 by the limiting part 12. When the humidifying inner core 3 has been working for a long time, the water in the humidifying inner core 3 can be squeezed out, so that the outer peripheral wall of the humidifying inner core 3 is moistened, thereby improving the humidification effect of the air.
[0063] The limiting part 12 is the inner wall of the first housing 1 facing the humidifying inner core 3, which can limit the humidifying inner core 3. The two ends of the humidifying inner core 3 abut against the first housing 1 and the second housing 2, respectively. In some embodiments, the limiting part 12 is a recessed platform formed by the inward of the first housing 1, which limits the humidifying inner core 3 and can squeeze the humidifying inner core 3. Specifically, the recessed platform is provided at the top of the first housing 1, and the bottom wall of the recessed platform is provided with a water injection hole 121. Since the recessed platform is concave, a water tank can be formed, so water can be poured directly into the water tank when water is injected. The water injection hole 121 connects the water tank and the receiving cavity, and water can enter the receiving cavity from the water injection hole 121 and be absorbed by the humidifying inner core 3.
[0064] An embodiment of the present invention provides a humidification device, which is at least partially disposed in an air duct. The portion of the humidification device extending into the air duct is provided with a ventilation hole 21. The flowing air passes through the ventilation hole 21 to the humidification core 3 and can carry away the water vapor on the humidification core 3, thereby achieving the purpose of humidifying the flowing air. In this way, the humidified flowing air enters the passenger cabin to humidify the passenger cabin space.
[0065] refer to Figure 3 In an embodiment of the present invention, an air duct assembly is also provided, which includes an air duct 100 and a humidification device provided in the embodiment of the present invention. The air duct 100 is equipped with the humidification device and has an air outlet, with an air outlet grille installed at the air outlet. The humidification device may be at least partially disposed inside the air duct or may be disposed outside the air duct 100, specifically hooked onto the air outlet grille.
[0066] The air duct 100 also has a mounting hole located upstream of the air outlet, and the mounting hole is fitted with the components provided in the above embodiment. The mating part is specifically a snap-fit part that engages with the mounting hole. In this way, the flowing air first passes through, is humidified, and then flows out through the air outlet, resulting in relatively humid air that meets the humidification requirements of the passenger cabin.
[0067] Specifically, the snap-fit portion includes a boss 22 and a snap-fit member 23. Both the boss 22 and the snap-fit member 23 are disposed on the circumferential sidewall of the second housing 2. The sidewall of the boss 22 facing the snap-fit member 23 abuts against the air duct 100, thereby limiting the second housing 2. At least two snap-fit members 23 are provided on the circumferential sidewall of the second housing 2. The snap-fit members 23 and the boss 22 are spaced apart along the axial direction of the second housing 2 to form a snap-fit groove for engaging with the air duct 100. After the snap-fit member 23 passes through the mounting hole, since the diameter of the boss 22 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 2. 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 23. This can prevent the second housing 2 from colliding with the air duct 100 and generating noise after violent shaking.
[0068] Since the humidification device described above is included, the air duct 100 of this embodiment of the invention has all the advantages and beneficial effects of the above embodiments, which will not be repeated here.
[0069] An embodiment of the present invention also provides a vehicle including the air duct assembly provided in the above embodiments.
[0070] To facilitate the installation of the air duct assembly, in some embodiments, the air duct 100 is a foot-blowing air duct. The humidifier installed in the foot-blowing air duct is less likely to be noticed by passengers in the passenger cabin, thus improving aesthetics.
[0071] Since the vehicle of this embodiment includes the aforementioned air duct components, it possesses all the advantages and beneficial effects of the aforementioned embodiments, which will not be repeated here.
