Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a humidifier. Background Technology

[0002] With the improvement of people's living standards and the pursuit of a healthy environment, humidifiers have become a necessity for many families. Humidifiers use humidifying components to humidify and ventilate, thereby increasing the humidity of indoor air and improving the comfort of the living environment.

[0003] However, in humidifiers of this technology, when the water tank is low on water, it is usually necessary to fill the tank directly through a water filling pipe. The noise of water flowing through the water filling pipe is relatively large, which reduces the user experience of the humidifier. Utility Model Content

[0004] This application discloses a humidifier in which the outlet of the water inlet pipe connected to the outside is not directly connected to the water tank, but instead fills the humidification component with water. The water overflowing from the humidification component then flows into the water tank, thereby reducing the water flow noise during the water filling process and improving the user experience.

[0005] To achieve the above objectives, this application discloses a humidifier, comprising: a housing with a water inlet at the top; a water inlet pipe disposed inside the housing and connected to the water inlet; a humidification component located inside the housing, with the water outlet of the water inlet pipe facing the top of the humidification component; and a water tank with the humidification component placed on top of the water tank, the water tank being at least partially connected to the humidification component.

[0006] In one possible implementation, a water distribution plate is provided on the top of the humidification component, the water outlet of the water injection pipe faces the water distribution plate, and a plurality of water passage holes are provided on the bottom wall of the water distribution plate; the water passage holes correspond to the humidification component in the vertical direction.

[0007] In one possible implementation, the water distribution plate includes a first sidewall and a second sidewall, the first sidewall and / or the second sidewall being connected to the bottom wall via a water guiding surface; the water guiding surface extends at an angle relative to the vertical direction to guide the water flow to the water passage.

[0008] In one possible implementation, the water distribution plate is provided with a guide rib on the side facing the humidification component, and the free end of the guide rib abuts against the humidification component.

[0009] In one possible implementation, the housing is provided with an air inlet, and the guide rib is located on the side of the water passage near the housing.

[0010] In one possible implementation, the water injection pipe includes multiple interconnected water injection pipe segments, with the lower water injection pipe segment sleeved over the upper water injection pipe segment.

[0011] In one possible implementation, two adjacent water injection pipe sections are sealed together.

[0012] In one possible implementation, the water inlet is sealed to the water inlet pipe.

[0013] In one possible implementation, the humidifier further includes a fan assembly, the fan assembly including a fan housing, the fan housing forming a water inlet channel communicating with the water inlet, and the water inlet pipe communicating with the water inlet through the water inlet channel.

[0014] In one possible implementation, the water injection pipes are configured to be at least two, and each of the at least two water injection pipes is connected to the water injection channel.

[0015] In one possible implementation, the water injection pipe and the fan casing are an integral structure.

[0016] In one possible implementation, the humidifier further includes: a water pump disposed within the water tank, the water pump being used to deliver water from the water tank to the humidification assembly; and a power supply bracket disposed within the housing, the power supply bracket being used to install power supply terminals for supplying power to the water pump, the power supply bracket including a first assembly portion having a flow channel, the first assembly portion being assembled to the water distribution tray, and the water injection pipe communicating with the first assembly portion to inject water into the water distribution tray.

[0017] In one possible implementation, the humidifier further includes a fan assembly disposed within the housing; the top of the housing includes an air guide section and a mounting section, the air guide section being connected to the exhaust port of the fan assembly; an overflow prevention groove is formed between the side wall of the air guide section and the mounting section, the water inlet is located within the overflow prevention groove, and the mounting section is used to install a control panel.

[0018] In one possible implementation, the air guide includes a first air guide surface and a second air guide surface, and an air guide channel is formed between the first air guide surface and the second air guide surface;

[0019] Wherein, the first air guide surface is formed as a curved surface that convexes radially outward along the fan assembly; and / or the second air guide surface is formed as a curved surface that convexes radially outward along the fan assembly.

[0020] In one possible implementation, the water injection pipe includes a first bend to avoid the fan assembly, and the inner wall of the water injection pipe at the first bend is a smooth curved surface.

[0021] In one possible implementation, the water injection pipe includes a second bend so that the water outlet faces the water distribution plate, and the inner wall of the second bend is a smooth curved surface.

[0022] In one possible implementation, the water tank includes: a tank body forming the water storage cavity; a water receiving tray disposed in the tank body, the water receiving tray being used to support the humidification component, a water guiding hole being provided on the side wall of the water receiving tray, the water guiding hole extending into an extension portion toward the water tank, and a predetermined gap being formed between the end of the extension portion and the tank body.

[0023] In one possible implementation, the length of the preset gap along the horizontal direction is L1, where L1 ≤ 0.5 mm.

[0024] Thus, by placing a water inlet at the top of the humidifier casing and guiding water flow to the humidification component through the inlet and water inlet pipe, the processes of wetting the humidification component and filling the water tank can be completed simultaneously. When the humidifier is initially turned on, the humidification component is already humidified, shortening the humidifier's response time. Furthermore, because the humidification component has high water absorption, it can buffer the impact of the water flow when it enters through the water inlet pipe, achieving silent water absorption and reducing splashing and vibration noise generated during the filling of the water tank.

Detailed Implementation

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0042] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0044] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0045] With the improvement of living standards and people's increasing attention to a healthy environment, humidifiers have become an indispensable home appliance for many families. Humidifiers humidify and ventilate the air through humidifying components, effectively increasing indoor humidity and improving the comfort of the living environment, playing an important role, especially in dry seasons or air-conditioned rooms.

[0046] However, in humidifiers of this technology, users typically need to refill the water tank directly through a filling pipe when it is low on water. The rapid flow of water within the pipe generates significant noise, especially at night or in quiet environments. This noise can significantly reduce the user experience and may even disrupt rest.

[0047] Based on this, this application provides a humidifier that uses a humidifying component with water absorption properties as an intermediate medium. When water is injected into the humidifying component with water absorption properties, the noise is significantly reduced. When the water overflowing from the humidifying component flows back into the water tank, the noise of water flowing into the water tank can be significantly reduced.

[0048] Please refer to the following: Figures 1 to 3 This application provides a humidifier 100. The humidifier 100 includes a housing 10, within which a receiving cavity 10a is formed. A humidification assembly 40, a fan assembly 60, and a water circuit assembly are disposed within the receiving cavity 10a. A water tank 50 may be disposed within the housing 10 or exposed outside the housing; for example, the housing 10 may overlap the top of the water tank 50.

[0049] like Figure 1 As shown, the housing 10 includes an air inlet 101 and an air outlet 102. The air inlet 101 is located on the side wall of the housing 10 and corresponds to the humidification component 40. The air outlet 102 is located on the top of the housing 10, and an airflow channel is formed between the air inlet 101 and the air outlet 102. The humidification component 40 is located within the airflow channel. The airflow entering the housing 10 from the air inlet 101 passes through the humidification component 40 to form humidified airflow, and then passes through the fan assembly 60 before being discharged from the air outlet 102, thereby humidifying the indoor environment.

[0050] The housing 10 serves as the exterior of the humidifier 100 and provides structural support and protection for the structural and electrical components of the humidifier 100 (e.g., the fan assembly 60 and the water circuit assembly). The water circuit assembly is used to deliver water from the water tank 50 to the humidification assembly 40 to keep the humidification assembly 40 moist.

[0051] In some embodiments, such as Figure 2 As shown, a water inlet 106 is provided on the top of the housing 10. When the water level in the water tank 50 of the humidifier 100 is low and water needs to be added to the water tank 50, water can be added to the humidifier 10 through the water inlet 106.

[0052] By placing the water inlet 106 on the top of the housing 10, water can be filled into the humidifier 100 from the top, making it convenient for users to fill the water. In addition, since the water tank 50 is located at the bottom of the humidifier 100, the top water filling scheme allows the water to flow towards the water tank 50 under the action of gravity, eliminating the need for other flow guiding structures.

[0053] In some embodiments, such as Figure 2 and Figure 3 As shown, the humidifier 100 includes a water inlet pipe 30. The water inlet pipe 30 is located inside the housing 10 and is connected to the water inlet 106.

[0054] The water inlet pipe 30 is located inside the housing 10. The water inlet pipe 30 is connected to the water inlet 106 to ensure a smooth and concentrated water flow path, reducing water dispersion or splashing.

[0055] In some embodiments, such as Figure 4 As shown, the humidification component 40 may include a wettable substrate 402.

[0056] The wettable substrate 402 is typically made of highly absorbent, tensile-resistant fibers or special composite materials, such as polyester fibers or nylon fibers. The wettable substrate 402 can quickly absorb and retain moisture. When airflow passes through the wettable substrate 402, gas-liquid contact is achieved, thereby forming a humidified airflow to increase the humidity of the indoor environment. The description of water flowing into or out of the humidification component 40 in this document can be understood as water flowing into or out of the wettable substrate 402.

[0057] In some embodiments, the water outlet of the water inlet pipe 30 faces the top of the humidification assembly 40. This allows water flowing from the water inlet 106 to directly flow into the top of the humidification assembly 40 under the guidance of the water inlet pipe 30. Based on the water absorption of the humidification assembly 40 and the effect of gravity on water, the water flowing from the water inlet 106 can be quickly absorbed by the humidification assembly 40, and the moisture can quickly and fully fill the wettable substrate 402. It is understood that if the water inlet pipe is not facing the top of the humidification assembly but rather to the side, a portion of the humidification assembly may remain in a dry state without absorbing water, affecting the humidification effect of the humidification assembly on the airflow.

[0058] In some embodiments, the humidifying component 40 is positioned on top of the water tank 50. The water tank 50 is at least partially connected to the humidifying component 40. When the water flow into the humidifying component 40 exceeds its water holding capacity, the excess water will overflow from the humidifying component 40 and flow into the water tank 50, thus completing the filling of the water tank 50 and enabling the humidifier 100 to perform humidification operations normally.

[0059] Thus, by providing a water inlet 106 at the top of the casing 10 of the humidifier 100, and guiding water flow to the humidification component 40 through the water inlet 106, the processes of humidifying the humidification component 40 and filling the water tank 50 can be completed simultaneously. When the humidifier 100 is initially turned on, the humidification component 40 is already in a humidified state, shortening the response time of the humidifier 100. Furthermore, because the humidification component 40 has high water absorption, when water flows into the humidification component 40 through the water inlet pipe 30, the humidification component 40 can buffer the impact of the water flow, achieving silent water absorption, thereby reducing the splashing and vibration noise generated during the filling of the water tank 50. Compared to related technologies where the water inlet pipe directly fills the water tank, the splashing and vibration noise of the water flow can be significantly reduced.

[0060] In some embodiments, the wettable substrate 402 can be a multilayer structure. This provides good water retention and increases the surface area for gas-liquid contact, thereby improving the humidification efficiency of the wettable substrate 402.

[0061] In some embodiments, such as Figures 2 to 4 As shown, a water distribution tray 20 is provided on the top of the humidification component 40. The water distribution tray 20 can be fitted onto the top of the humidification component 40. The water distribution tray 20 is used to fill the humidification component 40 with water. Figure 2 As shown, the outlet end of the water injection pipe 30 faces the water distribution plate 20.

[0062] In some embodiments, to improve the structural performance of the humidification assembly 40, the humidification assembly 40 may further include a support frame 401. The support frame 401 provides structural support for the wettable substrate 402.

[0063] The support frame 401 is typically constructed as a hollow barrel with a mesh structure to allow airflow. An annular, wettable substrate 402 covers the outer periphery of the support frame 401, corresponding to the air inlet holes provided on the side wall of the housing 10. It can be understood that if the wettable substrate 402 itself has supporting properties, the support frame 401 may not be necessary in the humidification assembly 40.

[0064] To simplify the structure, in some embodiments, such as Figure 4 As shown, the water distribution plate 20 can be integrated with the support frame 401.

[0065] In some embodiments, such as Figure 2 and Figure 3 As shown, when water flows out of the water inlet pipe 30, it first enters the water distribution pan 20 and then flows into the humidification component 40. The water distribution pan 20 can evenly disperse and guide the water flow to various areas of the humidification component 40, so that the water flow is not concentrated in a certain area of ​​the humidification component 40, but evenly covers the entire humidification component 40, thereby reducing the probability of local over-humidification or over-dryness of the humidification component 40.

[0066] It is understandable that by evenly filling the humidification component 40 with water through the water distribution plate 20, each area of ​​the humidification component 40 has sufficient water holding capacity, which can improve the humidification efficiency and humidification effect of the humidification component 40. If the water holding capacity of a certain area of ​​the humidification component 40 is insufficient, even if airflow passes through this area, effective gas-liquid exchange cannot occur, resulting in energy waste and reducing the humidification effect of the humidifier 100.

[0067] In some embodiments, such as Figure 2 As shown, the humidifying component 40 can be attached to the water tank 50 to facilitate easy disassembly and assembly between the humidifying component 40 and the water tank 50.

[0068] In some embodiments, such as Figure 5 As shown, the water tank 50 may include a water storage chamber 501. Water overflowing from the humidification component 40 may flow into the water storage tank 50.

[0069] Specifically, the water tank 50 may include a tank body 502 and a water receiving tray 503. The tank body 502 forms a water storage cavity 501, and the water receiving tray 503 is located on top of the tank body 502. The humidifying component 40 is detachably disposed on the water receiving tray 503, and the water receiving tray 503 provides structural support for the humidifying component 40. When the water holding capacity of the humidifying component 40 reaches its upper limit, the excess water will overflow from the humidifying component 40. The water receiving tray 503 may be provided with a water guide hole 504 so that the water overflowing from the humidifying component 40 flows into the water storage cavity 501 of the water tank 50.

[0070] In summary, the humidifying component 40 can absorb not only the water injected from the water inlet pipe 30, but also the water drawn from the water tank 50 by the water circuit component. The water drawn from the water circuit component can also flow into the water distribution pan 20. Regardless of whether the water source for humidifying the humidifying component 40 comes from the water inlet pipe 30 or the water circuit component, the water distribution pan 20 can evenly guide the water flow to the humidifying component 40 to achieve balanced water retention, thereby improving the humidification performance of the humidifying component 40.

[0071] In some embodiments, such as Figure 4 As shown, the water distribution pan 20 includes a water distribution tank 202. The water distribution tank 202 is constructed as a trough-shaped structure and has a certain volume to receive the water flowing into the water distribution pan 20 from the water injection pipe 30. The outlet end of the water injection pipe 30 faces the bottom of the water distribution tank 202, and the water flowing out of the water injection pipe 30 can be directly injected into the water distribution tank 202 to prevent water from splashing out.

[0072] In some embodiments, such as Figure 4As shown, the water distribution plate 20 is provided with multiple water passage holes 201. In the vertical direction, the water passage holes 201 correspond to the humidification component 40. In this way, the water flowing out of the water distribution plate 20 can flow directly into the humidification component 40 by gravity, improving the utilization rate of the water flowing out of the water injection pipe 30.

[0073] In some embodiments, a plurality of water passages 201 are arranged at circumferential intervals along the water distribution plate 20. In this way, the water flow in the water distribution tank 202 can be evenly guided to multiple areas of the humidification assembly 40.

[0074] It should be noted that some of the multiple water passages 201 are closer to the outlet of the water injection pipe 30, while others are farther away. However, by reasonably controlling the operating power of the water pump in the water circuit component, the volume of the water distribution tank 202, and the permeable area of ​​the water passages 201, water can flow out of each water passage 201 in the water distribution tank 202. The humidifying component 40 can absorb moisture from each water passage 201, so that the water flowing out of the water distribution pan 20 can be evenly distributed and cover the entire humidifying component 40.

[0075] In some embodiments, the opening size of the water passage 201 can be 2 mm to 5 mm.

[0076] It is understandable that if the opening size of the water passage 201 is too large, the water flow may not be able to reach every water passage, and instead concentrate in some water passages 201 at the outlet end of the water injection pipe 30. If the opening size of the water passage 201 is too small, it may affect the water permeability of the water distribution plate 20, causing the water injected by the water injection pipe 30 to not flow into the water tank 50 quickly. Controlling the opening size of the water passage 201 between 2mm and 5mm can balance the water permeability efficiency and the uniformity of water permeability.

[0077] In some embodiments, the number of water passage holes 201 can be multiple. Multiple water passage holes 201 can improve the water permeability efficiency of the water distribution holes.

[0078] In some embodiments, the depth of the water distribution plate 20 can be 10mm to 12mm, so that the water distribution plate 20 can store a certain amount of water and allow the water in the water distribution plate 20 to flow out evenly from the multiple water passages 201.

[0079] In some embodiments, such as Figure 4 As shown, the water distribution plate 20 includes a first side wall 203, a second side wall 204, and a bottom wall 205. A water passage hole 201 is provided on the bottom wall 205 of the water distribution plate 20.

[0080] In some embodiments, such as Figure 4As shown, the first sidewall 203 and / or the second sidewall 204 are connected to the bottom wall 205 via a water guiding surface 206. The water guiding surface 206 can be located on both sides of the water passage 201 to quickly concentrate and guide the water flow to the water passage 201.

[0081] Specifically, the water guiding surface 206 may include a first water guiding surface 206a and / or a second water guiding surface 206b. The first water guiding surface 206a is connected to the first side wall 203 and the bottom wall 205, and the second water guiding surface 206b is connected to the second side wall 204 and the bottom wall 205.

[0082] In this design, the end of the first water-guiding surface 206a connected to the first side wall 203 is higher than the end connected to the bottom wall 205. Similarly, the end of the second water-guiding surface 206b connected to the second side wall 204 is higher than the end connected to the bottom wall 205. This allows the water flowing into the water distribution plate 20 to be guided by the first water-guiding surface 206a and / or the second water-guiding surface 206b, concentrating its flow into the water passage 201, thus improving the permeability of the water distribution plate 20 and preventing water from accumulating and overflowing.

[0083] It is understood that by setting the first water guiding surface 206a and / or the second water guiding surface 206b, the water flow can be concentrated at the water passage 201, and the water flow will flow out of the water distribution plate 20 more efficiently. Unlike related technologies that set complex water guiding rib structures in the water receiving components, resulting in difficulty in cleaning scale, the water distribution plate 20 in this embodiment is easy to clean and has no dead corners for cleaning.

[0084] In some embodiments, such as Figure 6 As shown, the water distribution plate 20 is provided with a guide rib 207 on the side facing the humidification component 40, and the guide rib 207 abuts against the wettable substrate 402 of the humidification component 40.

[0085] Some of the water flowing out of the water passage 201 may flow along the water distribution plate 20 due to surface tension. The guide rib 207 extends from the water distribution plate 20 toward the water tank 50, and the free end of the guide rib 207 abuts against the wettable substrate 402. In this way, even if some water flows along the bottom wall 205 of the water distribution plate 20 after passing through the water passage 201, the guide rib 207 can stop this part of the water flow and guide this part of the water flow through the top of the wettable substrate 402 and into the wettable substrate 402.

[0086] In some embodiments, the guide rib 207 is located on the side of the water passage 201 near the housing 10. The guide rib 207 is located on the side of the water passage 201 and on the side of the water passage 201 near the housing 10.

[0087] Because the housing 10 is provided with an air inlet 101, the air inlet 101 communicates with the outside. The air inlet 101 includes multiple air inlets. The air inlet 101 is located on the side wall of the housing 10 and surrounds the outer perimeter of the housing 10. Along the height direction of the humidifier 100, that is, the vertical direction, the humidification component 40 is located inside the housing 10 and is set approximately corresponding to the air inlet 101, so that the airflow entering the air inlet 101 can have as much gas-liquid contact with the humidification component 40 as possible.

[0088] The guide rib 207 is positioned on the side of the water passage 201 near the housing 10. Because the guide rib 207 guides the water flow, the water flows more easily downwards along the guide rib 207, allowing the water to fill the humidification component 40 by gravity. If the guide rib 207 is not positioned on the side of the water passage 201 near the housing 10, during the water filling stage, since the fan component 60 may not have started working yet, the water flowing out of the water distribution pan 20 may easily splash onto the air inlet 101 on the housing 10. Some of the water may gather at the air inlet 101 and splash out of the humidifier 100 through the air inlet 101.

[0089] In this way, the guide rib 207 can not only cut off the water flow along the water distribution plate 20 affected by surface tension, but also reduce the probability of the water flow splashing to the air inlet 101 after flowing out of the water distribution plate 20, thereby improving the utilization rate of the water flow.

[0090] In some embodiments, such as Figure 2 As shown, the water injection pipe 30 includes multiple interconnected water injection pipe segments 30.

[0091] The water inlet pipe 30 is located inside the housing 10 and within the fan cavity 104. To avoid interference with the fan assembly 60 or other structural components within the fan cavity 104, the water inlet pipe 30 may need to be bent. The multi-segment structure of the water inlet pipe 30 allows for better adaptation to the spatial layout within the fan cavity 104 and flexible adjustment of its direction and angle, achieving a more rational arrangement between the water inlet pipe 30 and other components, thus improving the compactness of the humidifier 100.

[0092] In some embodiments, such as Figure 2 As shown, the lower water injection pipe segment 30 is fitted over the upper water injection pipe segment 30.

[0093] The lower water injection pipe segment 30 is sleeved on the outside of the upper water injection pipe segment 30, which can effectively enhance the overall structural stability of the water injection pipe 30, reduce the risk of loosening or falling off of the multi-segment structure of the water injection pipe 30 due to water flow impact or vibration, and reduce the occurrence of water overflow from the water injection pipe 30.

[0094] In some embodiments, two adjacent water injection pipe segments 30 are sealed together.

[0095] Specifically, the lower water injection pipe segment 30 is fitted over the upper water injection pipe segment 30, and a sealing ring can be installed between the lower water injection pipe segment 30 and the upper water injection pipe segment 30.

[0096] In some embodiments, the water inlet 106 is sealed to the water inlet pipe 30.

[0097] The two adjacent water injection pipes 30 segments and the water injection port 106 are all sealed together, so that the water flow in the water injection pipe 30 will not leak during the transmission process, which improves the reliability of the water injection path.

[0098] In some embodiments, such as Figure 2 As shown, along the circumference of the humidifier 100, the water inlet pipe 30 is positioned opposite the electrical control box 90.

[0099] The water injection pipe 30 is positioned opposite the electrical control box 90, allowing the water injection pipe 30 to be as far away from the electrical control box 90 as possible, thereby achieving water and electricity separation and improving the safety of the electrical control box 90.

[0100] In some embodiments, such as Figure 2 As shown, the humidifier 100 may include a partition 103. The partition 103 is located inside the housing 10 and divides the space inside the housing 10 into a fan chamber 104 and a humidification chamber 105. The fan chamber 104 is connected to the air outlet 102, and the humidification chamber 105 is connected to the air inlet 101.

[0101] The fan assembly 60 is located in the fan chamber 104 on one side of the partition 103, and the humidification assembly 40 and the water tank 50 are located in the humidification chamber 105 on the other side of the partition 103.

[0102] In some embodiments, such as Figure 2 As shown, the water injection pipe 30 includes a first bend 302 to avoid the blower assembly 60. The inner wall of the water injection pipe 30 at the first bend 302 is a smooth curved surface.

[0103] As mentioned earlier, in order to avoid interference with the fan assembly 60 or other structural components within the fan cavity 104, the water injection pipe 30 may need to be bent. After being connected to the water inlet 106, the water injection pipe 30 extends towards the side wall of the housing 10 and bends downward toward the water tank 50 to form a first bend 302, in order to adapt to the spatial layout within the fan cavity 104 and to give the fan assembly 60 sufficient volume.

[0104] The inner wall of the first bend 302 is a smooth curved surface. When the water flows vertically, the smooth curved surface can guide the water to slide smoothly, reducing the sound generated by the direct splashing of water and reducing noise during the water injection process.

[0105] In some embodiments, such as Figure 2 As shown, the water injection pipe 30 includes a second bend 303 so that the water outlet faces the water distribution plate 20. The inner wall of the water injection pipe 30 at the second bend 303 is a smooth curved surface.

[0106] After the water injection pipe 30 bends towards the housing 10 and extends downwards, the outlet end of the water injection pipe 30 may not correspond vertically with the humidification component 40 or the water distribution pan 20. Therefore, the water injection pipe 30 needs to be bent again to correspond with the water distribution pan 20, thereby improving the utilization rate of the water flowing out of the water injection pipe 30.

[0107] The inner wall of the second bend 303 is a smooth curved surface. When the water flows vertically, the smooth curved surface can guide the water to slide smoothly, reducing the sound generated by the direct splashing of water and reducing noise during the water injection process.

[0108] In some embodiments, such as Figure 2 As shown, the fan assembly 60 includes a fan housing 601. A fan wheel 602 is disposed inside the fan housing 601.

[0109] In some embodiments, such as Figure 7 and Figure 8 As shown, a water injection channel 604 is formed inside the fan casing 601, which communicates with the water inlet 106. The water inlet 106 is connected to the water injection pipe 30 through the water injection channel 604. The water injection channel 604 can be isolated from the airflow channel inside the fan rotor.

[0110] In this way, the connection between the water inlet 106 and the water inlet pipe 30 is realized by using the fan housing 601, which reduces the number of assembly parts of the humidifier 100 and lowers production and maintenance costs.

[0111] In some embodiments, such as Figure 7 As shown, the water inlet pipe 30 is located outside the fan housing 601. The water inlet pipe 30 can be integrated with the fan housing 601, thereby simplifying the number of structural components and assembly steps of the humidifier 100.

[0112] In some embodiments, such as Figure 7 As shown, at least two water injection pipes 30 can be configured. At least two water injection pipes 30 are respectively connected to the water injection channel 604.

[0113] At least two water inlet pipes 30 simultaneously supply water to the humidification component 40, which can speed up the water filling speed and shorten the water replenishment time of the water tank 50. This is especially suitable for large-capacity humidifiers 100, and can also improve the balanced water absorption of the humidification component 40.

[0114] In addition, at least two water injection pipes 30 can inject water into the water distribution plate 20 at the same time, which can make the water in the water distribution plate 20 fill the water distribution tank 202 more quickly, thereby further improving the water distribution performance of the water distribution plate 20.

[0115] In some embodiments, such as Figure 9 As shown, the water circuit assembly may include a water pump 70. The water pump 70 is detachably disposed within the water tank 50 and is used to deliver water from the water tank 50 to the humidification assembly.

[0116] In some embodiments, such as Figure 7 As shown, the water circuit assembly may also include a power supply bracket 80. The power supply bracket 80 is provided with power supply terminals for supplying power to the water pump 70. The power supply terminals can be electrically connected to the electrical control box 90 of the humidifier 100.

[0117] The electrical control box 90 is located inside the fan cavity 104, while the water pump 70 is detachably located inside the water tank 50. The power supply bracket 80 extends along the height direction of the humidifier 100 to electrically connect the electrical control box 90 and the water pump 70 through the power supply terminal.

[0118] In some embodiments, such as Figure 7 and Figure 8 As shown, the power supply bracket 80 includes a first assembly part 801. The first assembly part 801 is located on the top of the power supply bracket 80 and is used for assembly and installation with the water distribution pan 20.

[0119] The water distribution pan 20 may be provided with a second assembly part 208 that mates with the first assembly part 801. The second assembly part 208 and the first assembly part 801 may overlap, snap-fit, or plug into each other. In this way, the water distribution pan 20 provides structural support for one end of the power supply bracket 80, thereby improving the structural stability of the power supply bracket 80.

[0120] In some embodiments, the other end of the power supply bracket 80 can be fitted to the water tank 50, so that the power supply bracket 80 can be stably installed inside the housing 10.

[0121] In some embodiments, such as Figure 8 As shown, the first assembly portion 801 of the power supply bracket 80 has a flow channel. This flow channel can extend vertically through the first assembly portion 801, so that the first assembly portion 801 can both structurally cooperate with the water distribution plate 20 and guide the water flow.

[0122] In some embodiments, such as Figure 7 As shown, the water injection pipe 30 is connected to the first assembly part 801. That is, the water injection pipe 30 is fluidly connected to the flow channel of the first assembly part 801, so that the water flowing out of the water injection pipe 30 can be injected into the water distribution plate 20 through the first assembly part 801.

[0123] Thus, the power supply bracket 80 serves both as a power transmission component and a water guiding structure, achieving a compact design. By rationally isolating the power supply terminals and the first assembly part 801, the power supply bracket 80 achieves a compact design of "electricity and water on the same frame, but in different cavities." Furthermore, through the assembly of the first assembly part 801 with the water distribution plate 20, and the connection between the first assembly part 801 and the water injection pipe 30, the power supply bracket 80 and the water distribution plate 20 provide structural support for the water injection pipe 30, thereby improving the structural stability of the water injection pipe 30.

[0124] In some embodiments, such as Figure 2 As shown, the top of the housing 10 includes an air guide section 107. The fan assembly 60 includes an exhaust port 603, and the air guide section 107 communicates with the exhaust port 603 of the fan assembly 60. The airflow entering the housing 10 from the air inlet 101 is humidified by the humidification assembly 40, enters the air inlet of the fan housing 601, and is discharged from the exhaust port 603 of the fan housing 601 under the pressure of the impeller 602, and then flows out of the humidifier 100 through the air guide section 107. An air guide channel 1073 communicating with the exhaust port 603 is formed inside the air guide section 107.

[0125] In some embodiments, such as Figure 2 As shown, the air guide section 107 includes a first air guide surface 1071, which is formed as a curved surface that convexes outward along the radial direction of the impeller 602.

[0126] The surface of the air guide section 107 located within the air guide channel 1073 is designated as the first air guide surface 1071. The first air guide surface 1071 guides the airflow exiting the fan assembly 60. The first air guide surface 1071 is constructed as a curved surface, making it easier for the airflow to form the Coanda effect. The Coanda effect refers to the phenomenon that fluid tends to flow along a curved surface. When the airflow flows along the curved first air guide surface 1071, the airflow follows the curvature of the first air guide surface 1071, allowing the first air guide surface 1071 to guide the airflow more effectively and improve the aerodynamic efficiency of the fan assembly 60. Furthermore, it helps reduce airflow separation generated on the first air guide surface 1071, that is, reduces the generation of eddies and turbulence, thereby reducing aerodynamic noise.

[0127] In some embodiments, such as Figure 2 As shown, the air guide section 107 further includes a second air guide surface 1072 facing the first air guide surface 1071, and the second air guide surface 1072 is formed as a curved surface that convexes radially outward along the impeller 602. The aforementioned air guide channel 1073 is formed between the first air guide surface 1071 and the second air guide surface 1072.

[0128] The second guide surface 1072 is also used to guide the airflow exiting the fan assembly 60. When the airflow flows along the curved second guide surface 1072, the Coanda effect is easily formed, allowing the second guide surface 1072 to guide the airflow more effectively and improve the aerodynamic efficiency of the fan assembly 60. In addition, it helps to reduce airflow separation generated on the second guide surface 1072, that is, to reduce the generation of eddies and turbulence, thereby reducing aerodynamic noise.

[0129] Thus, the first air guide surface 1071 and / or the second air guide surface 1072 are formed as radially convex curved surfaces along the fan assembly 60. Airflow passing through the first air guide surface 1071 and the second air guide surface 1072 easily forms the Coanda effect, allowing the airflow to flow smoothly along the curved surfaces and reducing airflow separation and eddy current generation. The airflow exiting the air outlet 102 from the air guide channel 1073 can have a higher head, allowing the airflow to diffuse further and more evenly into the indoor environment, thereby improving the humidification effect and coverage of the humidifier 100. Simultaneously, the air guide channel 1073, which easily forms the Coanda effect, also reduces turbulence and noise generated by the airflow passing through the first air guide surface 1071 and the second air guide surface 1072, optimizing the performance of the humidifier 100.

[0130] In some embodiments, such as Figure 2 and Figure 10 As shown, the top of the housing 10 also includes a mounting section 108. The mounting section 108 is used to mount a control panel. An anti-overflow groove 109 can be formed between the air guide section 107 and the side wall of the mounting section 108.

[0131] Specifically, the mounting section 108 is constructed with an outwardly protruding structure away from the water tank 50, and the interior of the mounting section 108 can have an installation space. A control panel is provided on the top surface of the mounting section 108, including a display screen and / or control buttons, to facilitate user adjustment of the humidifier 100 parameters. Electronic components electrically connected to the control panel can be installed within the installation space. Because the mounting section 108 is constructed with an outwardly protruding structure, an overflow groove 109 can be formed between the air guide section 107 and the side wall of the mounting section 108, and the water inlet 106 is located within the overflow groove 109. Thus, when water is added to the water inlet 106, even if the capacity of the water inlet pipe 30 is limited, the water overflowing from the water inlet 106 will be collected by the overflow groove 109 and eventually flow back into the water inlet 106, reducing the occurrence of water overflowing the humidifier 100.

[0132] In some embodiments, such as Figure 11 As shown, the water tank 50 includes a water tray 503 and a tank body 502. The water tray 503 and the tank body 502 are detachably connected to facilitate thorough cleaning of the water tank 50.

[0133] Specifically, the water tray 503 can be attached to the open end of the tank 502. When the water tank 50 needs to be thoroughly cleaned, the water tray 503 can be removed from the tank 502. When the water tray 503 needs to be installed, it can be placed directly on the tank 502 to facilitate the installation and removal of the water tank 50.

[0134] In some embodiments, such as Figure 11 As shown, a water guide hole 504 is provided on the side wall of the water receiving tray 503, and there can be a gap between the water guide hole 504 and the bottom wall of the water receiving tray 503. When the water in the water receiving tray 503 reaches a certain height, it will flow out from the water guide hole 504 and enter the water tank 50.

[0135] In some embodiments, such as Figure 8 As shown, the water guide hole 504 extends into an extension 505 toward the water tank 50, and a preset gap is formed between the end of the extension 505 and the tank body 502.

[0136] The water guide hole 504 extends into the water tank 50, and the water flowing out of the water guide hole 504 will flow out along the extension 505. When the preset gap between the free end of the extension 505 and the inner wall of the tank 502 is small enough, the extension 505 can guide the water flowing out of the water guide hole 504 to the inner wall of the tank 502, so that the water flows slowly and smoothly along the inner wall of the tank 502.

[0137] The pre-set gap between the extension 505 and the inner wall of the housing 502 buffers and disperses the impact force of the water flow, reducing the impact of the water flow on the inner wall of the water tank 50 and further reducing noise during the water filling process. Unlike related technologies where the water flow directly impacts the bottom of the water tank 50 and generates significant noise, the humidifier 100 in this embodiment can significantly reduce the noise during the water filling process, making it particularly suitable for use at night or in quiet environments.

[0138] In some embodiments, such as Figure 11 As shown, the length of the preset gap along the horizontal direction is L1, where L1≤0.5mm.

[0139] When the preset gap L1 between the free end of the extension 505 and the inner wall of the tank 502 is small enough, the water flowing out of the extension 505 will be adsorbed onto the inner wall surface of the water tank 50 through capillary action, so that the water can flow smoothly along the inner wall of the water tank 50 instead of falling directly vertically from the free end of the extension 505.

[0140] In addition, the preset gap L1 between the free end of the extension 505 and the inner wall of the housing 502 also limits the cross-sectional area of ​​the water flow in the horizontal direction, which reduces the water flow velocity and forms laminar flow (smooth flow), making the downward flow of water quieter and more stable.

[0141] If the preset gap is too large, for example, L1 is greater than 0.5mm, the water flowing out from the extension 505 may not be adsorbed onto the inner wall of the water tank 50 based on capillary action, but will drip from the extension 505 into the water tank 50, which will increase the noise during the water filling process.

[0142] Specifically, L1 can be 0.1mm, 0.2mm, 0.3mm, 0.4mm or 0.5mm.

[0143] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
