It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0037] In the related art, if you want to increase the humidity in the passenger compartment, you need to install a humidifier. The humidifier is controlled by a controller to open and close to achieve the purpose of humidification. This results in the need to add a branch power harness when installing the humidifier, which increases the cost and tightens the layout space. Especially for vehicles that have already left the factory, major modifications are required to achieve the purpose of humidification.

[0038] like Figure 1 As shown, the humidification structure includes an outer shell and a humidification core 3, wherein the outer shell has a accommodating cavity and a ventilation hole 21, the ventilation hole 21 is connected to the accommodating cavity, and the outer peripheral wall of the outer shell is provided with a matching portion, which is used to communicate with the part to be installed; the humidification core 3 is arranged in the accommodating cavity, and air can pass through the ventilation hole 21 and flow through the humidification core 3.

[0039] Since the shell has a receiving cavity and a ventilation hole 21, the ventilation hole 21 is connected to the receiving cavity, and the humidifying core 3 is arranged in the receiving cavity, the flowing air can enter the receiving cavity through the ventilation hole 21 and flow through the humidifying core 3, and flow out from the ventilation hole 21 to take away the water vapor of the humidifying core 3, thereby humidifying the flowing air to improve the humidity of the passenger compartment. The outer peripheral wall of the shell is provided with a matching portion, and the matching portion is connected to the part to be installed so that the shell is fixed. Compared with the prior art, the humidifying structure provided by the embodiment of the present invention can humidify the passenger compartment without adding a wiring harness, reducing the humidification cost and requiring a small layout space. The humidifying structure can achieve cost reduction and efficiency improvement, solve the humidification working condition requirements of the passenger compartment, especially using the hot air properties of the winter duct itself to achieve natural humidification, thereby achieving high space utilization.

[0040] Since the humidification structure does not require additional branch power wiring harnesses, vehicles that have already left the factory can also be directly equipped with the humidification structure for use.

[0041] The part to be installed can be an air duct or an air outlet grille, that is, the humidifying structure can be at least partially arranged in the air duct, or can be arranged outside the air duct, specifically hooked at the air outlet grille.

[0042] After repeated contact with flowing air, the moisture in the humidifier core 3 is carried away by the flowing air, reducing the humidification effect. Therefore, in some embodiments, the housing is provided with a water injection hole 111, which is connected to the receiving chamber. Water enters the receiving chamber through the water injection hole 111 and is absorbed by the humidifier core 3. In this way, the air passing through the surface of the humidifier core 3 is humidified, thereby humidifying the passenger compartment. In certain seasons, when humidification of the passenger compartment is not required, there is no need to inject water into the humidifier core 3. Even if flowing air enters the housing, the humidifier core 3 is dry and will not humidify the flowing air.

[0043] Specifically, the humidifying core 3 includes a hydrophilic material such as absorbent cotton, so that the humidifying core 3 can store water and prevent the water from flowing out of the humidifying core 3 quickly.

[0044] In some embodiments, due to the gravity of water, water will accumulate at the bottom of the humidifier core 3. If the ventilation hole 21 extends all the way to the bottom wall 22 of the accommodating chamber and penetrates it, some water will drip into the air duct 100, causing water consumption to be faster, the water addition interval to become shorter, and the frequency of water addition to increase. For this reason, in some embodiments, the bottom end of the ventilation hole 21 is higher than the bottom wall 22 of the accommodating chamber, that is, the area enclosed by the bottom of the shell (the bottom end of the accommodating chamber) to prevent water from dripping. In addition, when the humidifying structure is installed horizontally or tilted in the air duct 100, the arrangement of the ventilation hole 21 in the shell can be adaptively adjusted to prevent water from dripping from the ventilation hole 21 due to gravity.

[0045] In some embodiments, the housing includes a first housing 1 and a second housing 2, which are connected to form a receiving cavity. The connection between the first housing 1 and the second housing 2 facilitates the overall arrangement and installation of the housing, especially in confined spaces, where one of the first housing 1 or the second housing 2 can be installed first, followed by the other.

[0046] Specifically, the second shell 2 is fixedly connected to the air duct 100 and the second shell 2 is partially arranged in the air duct 100. The second shell 2 is partially arranged in the air duct 100, which can avoid the problem that the second shell 2 is inconvenient to disassemble from the air duct 100 when it is completely placed in the air duct 100. In addition, it can also facilitate the installation of the second shell 2. In some embodiments, the second shell 2 is provided with a matching portion, and the second shell 2 is detachably connected to the part to be installed through the matching portion. For example, the second shell 2 is snap-fitted to the air duct 100 or connected by fasteners, which makes it easy to disassemble and replace the new humidification structure when the humidification structure as a whole fails. Of course, in some other embodiments, the second shell 2 can be welded to the air duct 100 as a whole by ultrasonic welding, and the first shell 1 is connected to the second shell 2 to form the above-mentioned accommodating cavity for accommodating the humidification inner core 3.

[0047] When the second shell 2 and the air duct 100 are fixedly connected by snapping, the matching portion is a snapping portion, and the snapping portion is snapped with the component to be installed, thereby achieving the purpose of quickly connecting the humidifying structure and the component to be installed.

[0048] Specifically, the clamping portion includes a boss 23 and a clamping member 24. Both the boss 23 and the clamping member 24 are disposed on the circumferential sidewall of the second housing 2. The sidewall of the boss 23 facing the clamping member 24 abuts against the air duct 100. That is, the diameter of the boss 23 is greater than the diameter of the mounting hole of the air duct 100. This prevents the second housing 2 from completely entering the air duct 100, thereby limiting the position of the second housing 2. At least two clamping members 24 are disposed on the circumferential sidewall of the second housing 2. The clamping members 24 and the boss 23 are spaced apart along the axial direction of the second housing 2 to form a clamping groove that engages with the air duct 100. The boss 23 is constrained within the clamping groove, thereby securing the second housing 2. In some embodiments, the height of the clamping groove is greater than the wall thickness of the air duct 100, but the heights should be approximately the same to minimize the gap between the air duct 100 and the clamping member 24. This prevents the second housing 2 from colliding with the air duct 100 and generating noise after a violent jolt.

[0049] In some embodiments, the number of the clamping members 24 is no less than two, and at least two clamping members 24 are arranged at equal intervals along the circumferential sidewall of the second housing 2. That is, the clamping members 24 are evenly arranged along the circumference of the second housing 2. This can improve the stability of the connection between the second housing 2 and the air duct 100. For example, the second housing 2 is provided with four clamping members 24.

[0050] In some embodiments, the clip 24 has a guide slope 241 that gradually approaches the central axis of the second housing 2 as it moves from the boss 23 toward the vent 21. The provision of the guide slope 241 facilitates the insertion of the clip 24 into the air duct 100. Furthermore, the end of the guide slope 241 proximal to the vent 21 smoothly connects to the circumferential sidewall of the second housing 2, preventing the connection from interfering with the assembly of the second housing 2 and the air duct 100.

[0051] The humidification structure divides the flowing air into three streams within the air duct 100. Two of these streams flow through the sides of the outer shell, while the other stream flows through the shell and contacts the humidification core 3 before converging into one stream. Although one of the streams contacts the humidification core 3, due to the limited space in the outer shell, the total amount of air entering the shell is much less than the amount of air flowing out of the air outlet. To increase the total amount of air entering the shell and thus the humidification level, the length of the vents 21 not directly facing the connector 24 is greater than the length of the vents 21 directly facing the connector 24. This increases the total amount of air entering the shell without interfering with the connector 24, thereby increasing the humidity in the passenger compartment.

[0052] In some embodiments, the first and second housings 1 and 2 are detachably connected. This allows for quick disassembly and inspection of the humidification mechanism should a malfunction occur, allowing for quick replacement of the malfunctioning component with a replacement. Furthermore, the detachable connection facilitates cleaning of the first and second housings 1 and 2, preventing mold and mildew in the humidifier core 3, the first and second housings 1 and 2, and facilitates replacement of the humidifier core 3. For example, when the first shell 1 and the second shell 2 are detachably connected, the first shell 1 and the second shell 2 can be threadedly connected. More specifically, the first shell 1 is provided with an external thread, and the second shell 2 is provided with an internal thread. The first shell 1 extends into the second shell 2 and the two are screwed together through the internal thread and the external thread. Of course, in some other embodiments, the first shell 1 and the second shell 2 can be connected by fasteners, and the fasteners pass through the first shell 1 and enter the second shell 2, thereby making the two detachable. In addition, in some other embodiments, the fasteners can also pass through the first shell 1 and the second shell 2 in sequence to connect with the air duct 100, thereby achieving the purpose of detachable connection between the first shell 1, the second shell 2 and the air duct 100. For example, the fasteners are screws.

[0053] Of course, in some other embodiments, the first shell 1 and the second shell 2 may also be fixedly connected by ultrasonic welding.

[0054] Regardless of how the first shell 1 and the second shell 2 are connected, when water flows through the junction of the two, water may flow out from the junction of the two. For this reason, in some embodiments, part of the first shell 1 extends into the second shell 2. In this way, when water flows from the first shell 1 to the second shell 2, part of the first shell 1 extends into the second shell 2, which can isolate and divert the water, prevent water from flowing out from the junction of the first shell 1 and the second shell 2, and thus play a sealing role.

[0055] Since the humidifying core 3 is disposed in the accommodating chamber, if the space of the accommodating chamber is large enough, the humidifying structure may vibrate after being subjected to severe bumps, causing uneven humidity in various parts of the humidifying core 3, and the contact area of ​​the humidifying core 3 with the flowing air is reduced during the vibration process. For this reason, in some embodiments, the first shell 1 is provided with a limiting portion 11, which is offset against the humidifying core 3. The provision of the limiting portion 11 can play a certain limiting role on the humidifying core 3, preventing the humidifying core 3 from shaking after being subjected to strong vibration. It can not only prevent the water in the humidifying core 3 from being thrown into the air duct 100 under the action of acceleration during the vibration process of the humidifying core 3, causing the humidifying core 3 to be dehydrated, but also prevent the vibration of the humidifying core 3 from colliding with the shell to generate noise.

[0056] The limiting portion 11 is the inner wall of the first shell 1 facing the humidifying core 3. The inner wall of the first shell 1 facing the humidifying core 3 can limit the humidifying core 3. The two ends of the humidifying core 3 are respectively against the first shell 1 and the second shell 2. In some embodiments, the limiting portion 11 is a concave platform formed by the inward concave of the first shell 1, so that the concave platform limits the humidifying core 3. Specifically, the concave platform is arranged at the top of the first shell 1, and the bottom wall of the concave platform is provided with a water injection hole 111. Since the concave platform is concave, a water trough can be formed. In this way, water can be poured directly into the water trough when filling water. The water injection hole 111 connects the water trough with the accommodating cavity, and water can enter the accommodating cavity from the water injection hole 111 and be absorbed by the humidifying core. Of course, in other embodiments, the limiting portion 11 can be a limiting column or a limiting ring arranged at the second end of the first shell 1, and the water injection hole 111 is arranged on the end face of the second end of the first shell 1.

[0057] In some embodiments, the first shell 1 partially extends into the second shell 2. Since the water injection hole 111 is set on the first shell 1, if the first shell 1 does not extend into the second shell 2, water may flow out through the connection between the first shell 1 and the second shell 2. The first shell 1 partially extends into the second shell 2, which will divert the water. When the water passes between the first shell 1 and the boss 23, it will be diverted to the area enclosed by the second shell 2 instead of flowing out, thereby achieving a sealing effect.

[0058] The ventilation holes 21 are arranged on the second shell 2, and multiple ventilation holes 21 are arranged at intervals along the circumference of the second shell 2, wherein a part of the ventilation holes 21 serves as air outlet holes, and another part of the ventilation holes 21 serves as air inlet holes. More specifically, the multiple ventilation holes 21 are evenly distributed along the circumference of the second shell 2, thereby ensuring that the air volume of each ventilation hole 21 is more balanced. In addition, the number of ventilation holes 21 is multiple, which can increase the total amount of air entering and exiting the outer shell.

[0059] In some embodiments, the ventilation holes 21 are provided on the circumferential sidewalls of the second housing 2. When the first housing 1 and the second housing 2 are connected, the minimum distance between the ventilation holes 21 and the bottom wall 22 of the accommodating chamber is less than the distance between the bottom wall 12 of the first housing and the bottom wall 22 of the accommodating chamber. In this way, the first housing 1 does not completely block the ventilation holes 21, ensuring that the flowing air enters the ventilation holes 21 and contacts the humidifying core 3, thereby ensuring the humidification effect on the flowing air. It is understandable that the bottom wall of the second housing 2 is the bottom wall 22 of the accommodating chamber.

[0060] For example, the shape of the ventilation hole 21 is circular or elongated. Of course, in other embodiments, it can also be triangular or polygonal, or irregular in shape, as long as it can ensure that the flowing air enters the accommodating cavity formed by the shell.

[0061] In some embodiments, to prevent the first housing 1 from partially blocking the ventilation holes 21 and thereby reducing the contact area between the flowing air and the humidifying inner core 3, the distance between the first housing bottom wall 12 and the bottom wall 22 of the accommodating chamber is greater than the maximum distance between the ventilation holes 21 and the bottom wall 22 of the accommodating chamber. In this way, after the first housing 1 and the second housing 2 are connected, the ventilation holes 21 are not blocked by the first housing 1 and are fully open. As a result, all the flowing air entering the ventilation holes 21 can contact the humidifying inner core 3 and be humidified, thereby ensuring the humidification effect and ensuring that the total amount of flowing air flowing out is not reduced.

[0062] In some embodiments, the bottom ends of the ventilation holes 21 are higher than the bottom wall 22 of the accommodating cavity, so that the bottom of the accommodating cavity can hold water, and the water gathers at the bottom of the shell (that is, the bottom of the accommodating cavity) under the action of gravity, which can prevent the water from dripping under the action of gravity.

[0063] When the ventilation hole 21 is a long strip hole, such as Figure 1As shown, the ventilation holes 21 are provided on the circumferential side wall of the second shell 2. There are multiple ventilation holes 21, and the multiple ventilation holes 21 are evenly distributed along the circumference of the second shell 2. The length direction of the ventilation holes 21 extends along the axial direction of the second shell 2. In this way, more air flows into the shell, which can increase the total amount of air moistened by the humidification core 3, thereby achieving a good humidification effect. The ventilation holes 21 have a first wall 211 and a second wall 212 that are arranged opposite each other along the axial direction of the second shell 2. The distance between the first wall 211 and the bottom wall 22 of the accommodating cavity is smaller than the distance between the second wall 212 and the bottom wall 22 of the accommodating cavity. The second wall 212 is closer to the first shell 1 than the first wall 211. When the humidification structure is in a vertical installation state, the first wall 211 is placed below the second wall 212. In order to ensure that the flowing air can enter the outer shell from the ventilation hole 21, the distance between the first shell bottom wall 12 and the bottom wall 22 of the accommodating cavity is greater than the distance between the first wall 211 of the ventilation hole 21 and the bottom wall 22 of the accommodating cavity. This arrangement allows the flowing air to enter the outer shell through the ventilation hole 21 and come into contact with the humidification core 3 to be humidified.

[0064] In addition, the first wall 211 of the ventilation hole 21 is higher than the bottom wall 22 of the accommodating cavity, so that the bottom of the accommodating cavity can hold water, and the water gathers at the bottom of the second shell 2, that is, the bottom of the accommodating cavity, under the action of gravity, which can prevent the water from dripping under the action of gravity.

[0065] In some embodiments, the distance between the bottom wall 12 of the first housing and the bottom wall 22 of the accommodating cavity is greater than the distance between the second wall 212 of the vent 21 and the bottom wall 22 of the accommodating cavity. In this way, after the first housing 1 and the second housing 2 are connected, the vent 21 is not blocked by the first housing 1, and all the flowing air entering the vent 21 can come into contact with the humidifying core 3 and be humidified, thereby ensuring the humidification effect and ensuring that the total amount of flowing air flowing out is not less than the total amount of flowing air entering the housing.

[0066] An embodiment of the present invention provides a humidification structure, which is at least partially arranged in the air duct 100. The part of the humidification structure extending into the air duct 100 is provided with ventilation holes 21. The flowing air passes through the ventilation holes 21 to the humidification inner core 3 and can take away the water vapor on the humidification inner core 3, thereby achieving the purpose of humidifying the flowing air. The humidified flowing air enters the passenger compartment to humidify the passenger compartment space.

[0067] Continue to refer Figure 1 An embodiment of the present invention also provides an air duct assembly, which includes a part to be installed and a humidification structure provided in an embodiment of the present invention. The part to be installed includes an air duct 100 and an air outlet grille. The air duct 100 and / or the air outlet grille are installed with a humidification structure. The air duct 100 has an air outlet, and the air outlet grille is installed at the air outlet.

[0068] The air duct 100 also has a mounting hole, located upstream of the air outlet, into which the humidification structure provided in the above-described embodiment is mounted. The mating portion is specifically a snap-fitting portion that engages with the mounting hole. This allows the flowing air to first pass through the humidification structure, where it is humidified, before exiting through the air outlet. The exiting air is relatively moist, meeting the humidification requirements of the passenger compartment.

[0069] Specifically, the clamping portion includes a boss 23 and a clamping member 24. Both the boss 23 and the clamping member 24 are provided on the circumferential sidewall of the second housing 2. The sidewall of the boss 23 facing the clamping member 24 abuts against the air duct 100, thereby limiting the position of the second housing 2. At least two clamping members 24 are provided on the circumferential sidewall of the second housing 2. The clamping members 24 and the boss 23 are spaced apart along the axial direction of the second housing 2 to form a clamping groove for clamping with the air duct 100. After the clamping member 24 passes through the mounting hole, the air duct 100 is constrained within the clamping groove because the diameter of the boss 23 is greater than the diameter of the mounting hole, thereby securing the second housing 2. In some embodiments, the height of the clamping groove is greater than the wall thickness of the air duct 100, but the heights should be approximately the same to minimize the gap between the air duct and the clamping member 24. This can prevent the second housing 2 from colliding with the air duct 100 and generating noise after a violent jolt.

[0070] Since the air duct of the embodiment of the present invention includes the above-mentioned humidification structure, it has all the advantages and beneficial effects of the above-mentioned embodiments, which will not be described in detail here.

[0071] An embodiment of the present invention further provides a vehicle, comprising the air duct assembly provided in the above embodiment.

[0072] In order to facilitate the installation of the humidifying structure, in some embodiments, the air duct 100 is a foot-blowing air duct. After the humidifying structure is installed at the foot-blowing air duct 100, it is not easy to be discovered by passengers in the passenger compartment, and the aesthetics are also improved.

[0073] Since the vehicle includes the above-mentioned air duct assembly, the vehicle of the embodiment of the present invention has all the advantages and beneficial effects of the above-mentioned embodiments, which will not be described in detail here.

[0074] Furthermore, the above are merely preferred embodiments of the present invention and the technical principles employed.
