Description

Technical Field

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

[0002] Mist-free humidifiers, used to improve indoor air humidity, are widely used in homes and offices. A typical humidifier includes a liquid tank, water pump, evaporative cooling pad, and fan. The pump delivers water to the evaporative cooling pad, and the air passing through the moistened pad is humidified before being introduced into the room.

[0003] Scale buildup in the storage tank after prolonged use, coupled with the fact that the water pump is typically fixed inside the tank, makes cleaning and maintenance of both inconvenient. Even when some humidifiers incorporate a detachable design for the storage tank and water pump, the disassembly process is complex, requiring multiple attempts to separate the pump. Furthermore, misalignment during reinstallation can affect the humidifier's operational stability, reducing its ease of use. Utility Model Content

[0004] This application provides a humidification device in which the water pump assembly is easy to detach from the liquid storage tank, making it convenient for users to clean the water pump assembly and improving the ease of use of the humidification device.

[0005] This application provides a humidification device, comprising: a liquid storage tank having a liquid storage cavity, the bottom wall of the liquid storage tank including a limiting recess, and the top of the liquid storage tank including a first limiting portion extending radially into the liquid storage cavity; and a water pump assembly detachably disposed within the liquid storage cavity, at least a portion of the water pump assembly being able to extend into the limiting recess to limit and engage with the limiting recess, the limiting recess limiting the water pump assembly circumferentially along the liquid storage tank, and the water pump assembly including a second limiting portion that limits and engages with the first limiting portion to limit the water pump assembly along the height direction of the liquid storage tank.

[0006] In one possible implementation, the liquid storage tank includes an opening communicating with the liquid storage cavity, and the first limiting portion is formed at the opening and extends circumferentially along the liquid storage tank to form a retaining edge.

[0007] In one possible implementation, the pump assembly includes a drive section exposed outside the reservoir;

[0008] When the water pump assembly is in the working position, the first limiting part is farther away from the bottom wall of the liquid storage tank than the second limiting part, so as to limit the water pump assembly along the height direction;

[0009] When the pushing part is subjected to a pushing force along the radial direction, the second limiting part separates from the first limiting part, and when the water pump assembly is subjected to a lifting force along the height direction, the water pump assembly moves out of the limiting recess to become detachable relative to the storage tank.

[0010] In one possible implementation, a fitting gap is formed between the pushing part and the second limiting part along the height direction, and when the water pump assembly is in the working position, the first limiting part extends into the fitting gap.

[0011] In one possible implementation, the limiting recess includes a limiting sidewall that is opposite to the sidewall of the liquid storage tank.

[0012] When the pushing part is subjected to the pushing force but not the lifting force, the limiting sidewall abuts against the water pump assembly to return the water pump assembly to the working position.

[0013] In one possible implementation, the pump assembly includes a sliding fit portion that is arc-shapedly connected to the side wall and bottom wall of the pump assembly facing the storage tank.

[0014] When the pushing part is subjected to the pushing force, or during the process of the water pump assembly resetting to the working position, the sliding mating part can slide along the side wall of the liquid storage tank.

[0015] In one possible implementation, the number of the second limiting portions is at least two, and the at least two second limiting portions are arranged at intervals along the circumferential direction.

[0016] In one possible implementation, the liquid storage tank includes a resilient latch, and the pushing part includes an engaging part that can engage with the resilient latch for limiting.

[0017] The liquid storage tank includes an assembly part, which is disposed on the first limiting part and extends along the height direction to be assembled with the water receiving tray of the humidification device.

[0018] The assembly portion forms clearance notches at both ends along the circumferential direction and extends into the liquid storage tank at the clearance notches, and the elastic buckle is formed on the portion of the assembly portion extending into the liquid storage tank.

[0019] In one possible implementation, the pump assembly includes an inlet portion capable of communicating with the liquid storage chamber, with at least a portion of the inlet portion exposed outside the limiting recess.

[0020] In one possible implementation, the water inlet includes a plurality of water inlets, at least some of which have their lower edges higher than or flush with the bottom wall of the storage tank, and at least one of the water inlets has its lower edge lower than the bottom wall of the storage tank.

[0021] In one possible implementation, the humidification device further includes:

[0022] A water receiving tray, which is detachably connected to the liquid storage tank;

[0023] A humidifying component is detachably mounted on the water receiving tray. The humidifying component includes a water supply pipe that passes through the water receiving tray and communicates with the water pump assembly.

[0024] In one possible implementation, the water receiving tray includes a third limiting portion, with at least a portion of the water pump assembly extending into the interior of the third limiting portion along the height direction, the third limiting portion providing a circumferential limit to the water pump assembly.

[0025] In one possible implementation, the pump assembly includes a power supply interface extending from the third limiting portion.

[0026] In one possible implementation, the free end of the first limiting portion extends along the height direction to form an assembly portion, and the water receiving tray overlaps the assembly portion.

[0027] In one possible implementation, the water receiving tray includes a receiving groove for containing scale inhibitors, the receiving groove being provided with a drain gap facing a first sidewall of the water pump assembly, and the drain gap having a predetermined distance from the first sidewall.

[0028] The first sidewall is inclined relative to the height direction.

[0029] In one possible implementation, the receiving tank includes a second sidewall opposite to the first sidewall, and the drain gap is disposed on the second sidewall and extends through to the bottom wall of the receiving tank.

[0030] In one possible implementation, the bottom wall of the receiving tank is inclined relative to the horizontal plane, and the drain gap is connected to the end of the bottom wall of the receiving tank near the liquid storage tank.

[0031] In one possible implementation, the water receiving tray is further provided with an overflow baffle extending along the height direction, the upper edge of the overflow baffle being higher than the opening of the receiving tank, so that liquid overflowing from the humidification component gathers into the receiving tank.

[0032] In one possible implementation, the pump assembly includes:

[0033] The housing includes a receiving cavity, the second limiting portion is disposed on the housing, and the housing is detachable relative to the liquid storage cavity;

[0034] A water level detection component is disposed in the housing and located within the receiving cavity.

[0035] The humidification device provided in this application embodiment forms multiple positioning and stable constraints on the water pump assembly through the limiting recess on the bottom wall of the liquid storage tank and the limiting engagement of the lower part of the water pump assembly, as well as the engagement of the first limiting part and the second limiting part on the top of the liquid storage tank. This multi-limiting method not only achieves the stability of the relative position of the water pump assembly and the liquid storage tank during operation, but also enables quick disassembly and assembly without tools, which can be completed by the user with one hand through a "push and lift" action of the water pump assembly, improving the ease of use and maintenance of the humidification device. At the same time, the convenient disassembly method encourages users to perform regular cleaning, reducing the risk of scale accumulation and microbial growth in the liquid storage tank, thereby improving the long-term hygiene and air cleanliness of the humidification device.

[0051] 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.

[0052] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0053] 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.

[0055] 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.

[0056] Suitable air humidity is an important condition for a comfortable living environment, so humidifiers have gradually become a common appliance in many homes and offices.

[0057] Humidifiers using related technologies commonly suffer from problems such as inconvenient disassembly and cleaning of the water pump assembly. For example, disassembling the water pump assembly often requires tools, multiple rotations or pressing of hidden clips, and must be aligned at a specific angle to remove it, making the operation cumbersome. Due to structural limitations, users find it difficult to regularly clean the water pump assembly and the liquid storage tank, which can easily lead to the accumulation of scale or the growth of microorganisms after long-term use, affecting the cleanliness of the air output from the humidifier.

[0058] Based on this, the present application provides a humidification device with a water pump assembly that is easy to disassemble and assemble, thereby helping users to better maintain the hygienic condition of the humidification device and improving the ease of use and cleanliness of the humidification device.

[0059] like Figure 1 and Figure 2As shown, this application embodiment provides a humidification device 1, which includes a liquid storage tank 10 and a water pump assembly 20. The liquid storage tank 10 has an internal cavity for containing humidifying liquid. The water pump assembly 20 is detachably disposed within the liquid storage tank 10 to draw liquid from the liquid storage tank 10 and deliver it to the humidification component 40 of the humidification device. The humidification component 40 may include a highly absorbent, wettable substrate to promote gas-liquid exchange between the airflow and water passing through the humidification component 40.

[0060] like Figure 2 and Figure 3 As shown, the bottom wall of the liquid storage tank 10 includes a limiting recess 102, which is a region recessed downward from the surface of the bottom wall. That is, along the height direction or vertical direction of the humidifying device 1, the bottom surface of the limiting recess 102 is lower than the bottom wall of the liquid storage tank 10. The shape of the limiting recess 102 can be adapted to the lower profile of the water pump assembly 20.

[0061] To achieve stable positioning of the water pump assembly 20, at least a portion of the water pump assembly 20, namely the lower part of the water pump assembly 20, can be inserted into and accommodated within the limiting recess 102. This limiting fit allows the inner wall of the limiting recess 102 to circumferentially limit the lower part of the water pump assembly 20, preventing the water pump assembly 20 from rotating or shifting horizontally within the liquid storage chamber 101, thus maintaining the water pump assembly 20 in the predetermined installation orientation.

[0062] like Figure 3 , Figure 4 and Figure 5 As shown, the top of the liquid storage tank 10 has a first limiting part 103. The first limiting part 103 is a protrusion or flange extending from the inner wall of the liquid storage tank 10, along the radial direction of the liquid storage tank 10, toward the central axis of the liquid storage tank 10, into the interior of the liquid storage tank 10. "Radial" can be understood as: a direction that points perpendicularly outward from the central axis of the humidification device (or conversely, perpendicularly outward to the central axis).

[0063] like Figure 2 , Figure 6 and Figure 7 As shown, the water pump assembly 20 includes a second limiting portion 201. The second limiting portion 201 corresponds to the first limiting portion 103. When the water pump assembly 20 is installed into the storage tank 10, the lower part of the water pump assembly 20 enters the limiting recess 102 on the bottom wall of the storage tank 10, and the second limiting portion 201 of the water pump assembly 20 engages or contacts the first limiting portion 103 at the top of the storage tank 10. The limiting cooperation of the first limiting portion 103 and the second limiting portion 201 forms a constraint on the water pump assembly 20 along the height direction (i.e., the vertical direction) of the storage tank 10, preventing the water pump assembly 20 from moving vertically. The second limiting portion 201 can be constructed as a protrusion or a flange.

[0064] like Figure 5 As shown, the first limiting part 103 extends radially into the interior of the liquid storage chamber 101, forming a limiting structure extending horizontally. The second limiting part 201 can also be constructed as a protrusion. When it is necessary to disassemble the water pump assembly 20, the user applies a horizontal thrust toward the center of the liquid storage tank 10 to the water pump assembly 20, which causes radial misalignment between the second limiting part 201 and the first limiting part 103, thereby releasing the vertical engagement constraint between the two.

[0065] No tools are needed to disassemble the water pump assembly 20; the user can remove it from the reservoir 10 with one hand. The user should gently push the water pump assembly 20 inwards to release the engagement of the first limiting part 103 with the second limiting part 201, and then pull the water pump assembly 20 upwards to separate it from the limiting recess 102 on the bottom wall of the reservoir 10, thus achieving quick and convenient disassembly. For assembly, the process is reversed. The lower part of the water pump assembly 20 is aligned with and placed into the limiting recess 102, and then the water pump assembly 20 is pushed outwards to engage the second limiting part 201 with the first limiting part 103. This can also be done with one hand.

[0066] Thus, the humidifier 1 provided in this embodiment forms multiple positioning and stable constraints on the water pump assembly 20 through the limiting recess 102 on the bottom wall of the liquid storage tank 10 and the limiting engagement between the lower part of the water pump assembly 20, and the engaging of the first limiting part 103 and the second limiting part 201 on the top of the liquid storage tank 10. This multiple limiting method not only ensures the stability of the relative position of the water pump assembly 20 and the liquid storage tank 10 during operation, but also enables quick disassembly and assembly without tools, requiring only one hand from the user, through a simple push and pull motion of the water pump assembly 20, thus improving the usability and maintenance convenience of the humidifier 1. Simultaneously, the convenient disassembly method encourages users to perform regular cleaning, reducing the risk of scale buildup and microbial growth inside the liquid storage tank 10, thereby improving the long-term hygiene and air cleanliness of the humidifier 1.

[0067] like Figure 3 and Figure 5 As shown, in some embodiments, the liquid storage tank 10 includes an opening 104 communicating with the liquid storage cavity 101, and a first limiting portion 103 is formed at the opening 104 and extends circumferentially along the liquid storage tank 10 to form a retaining edge.

[0068] In addition to providing vertical restriction for the water pump assembly 20, the first limiting part 103 can also be reused as a waterproof guard for the liquid storage tank 10. When the liquid storage tank 10 needs to be moved, the first limiting part 103 surrounding the circumference of the liquid storage tank 10 can prevent the humidifying liquid from flowing out through the opening 104 of the liquid storage chamber 101.

[0069] Thus, without the need to add any additional parts, the first limiting part 103 can not only maintain the structure of the water pump assembly 20, but also improve the protective performance of the liquid storage tank 10, further enhancing the practicality and reliability of the humidification device 1.

[0070] like Figure 6 and Figure 7 As shown, in some embodiments, the pump assembly 20 includes a pushing part 202 that is exposed outside the reservoir 10. That is, in the vertical direction, the pushing part 202 is higher than the top edge of the reservoir 10 and the first limiting part 103.

[0071] When disassembling the water pump, the user can access and apply force to the pusher 202. The user can easily perform the operations of "pushing" inward and "lifting" upward on the pusher 202 without inserting fingers into the reservoir 10 or touching other parts.

[0072] When the water pump assembly 20 is in the working position, the first limiting part 103 is farther away from the bottom wall of the liquid storage tank 10 than the second limiting part 201, so as to limit the water pump assembly 20 in the height direction.

[0073] like Figure 5 As shown, the first limiting part 103 can form a structural constraint on the water pump assembly 20 from above, thereby reliably limiting the water pump assembly 20 in the height direction and preventing the water pump assembly 20 from moving upward due to vibration or movement during use. The first limiting part 103 is positioned above the second limiting part 201, meaning that the first limiting part 103 uses its spatial position to block the second limiting part 201 to achieve longitudinal limiting of the water pump assembly 20. Compared to the snap-on limiting method that relies on elastic deformation, the cooperation between the first limiting part 103 and the second limiting part 201 eliminates the risk of engagement failure caused by fatigue, creep, or stress relaxation of the elastic material. Even under long-term use and frequent disassembly / reassembly conditions, a consistent limiting effect can be maintained, improving the durability of the humidification device 1.

[0074] When the pushing part 202 is subjected to a radial pushing force, the second limiting part 201 separates from the first limiting part 103, and when the water pump assembly 20 is subjected to a lifting force in the height direction, the water pump assembly 20 moves out of the limiting recess 102 and becomes detachable relative to the liquid storage tank 10.

[0075] Thus, the disassembly of the water pump assembly 20 can be achieved in two consecutive steps: First, when the pushing part 202 is subjected to a radial pushing force along the reservoir 10, the pushing part 202 undergoes a slight horizontal displacement, causing the second limiting part 201 to disengage or come into contact with the first limiting part 103. Then, when the water pump assembly 20 is subjected to a lifting force along the height direction, the lower part of the water pump assembly 20 can be disengaged from the limiting recess 102, thereby completing the disassembly from the reservoir 10.

[0076] Such as 6 and Figure 7 As shown, in some embodiments, a mating gap 203 is formed between the pushing part 202 and the second limiting part 201 along the height direction.

[0077] When the water pump assembly 20 is in the working position, the first limiting part 103 extends into the mating gap 203. Along the height direction, the thickness of the mating gap 203 can be slightly greater than the thickness of the first limiting part 103, thereby providing space for slight tilting of the water pump assembly 20 during disassembly while simultaneously fulfilling the limiting function of the first limiting part 103. When the user applies a radial thrust to the pushing part 202, the water pump assembly 20 can undergo a slight angular deflection, allowing the user to easily release the limiting state between the first limiting part 103 and the second limiting part 201.

[0078] like Figure 3 and Figure 5 As shown, in some embodiments, the limiting recess 102 includes a limiting sidewall 1021. The limiting sidewall 1021 is opposite to the sidewall of the liquid storage tank 10.

[0079] When the pusher 202 is subjected to a pushing force but not a lifting force, the limiting sidewall 1021 abuts against the water pump assembly 20 to return the water pump assembly 20 to the working position.

[0080] When the user applies a radial pushing force to the pushing part 202 but has not yet applied an upward pulling force, the water pump assembly 20 will rotate slightly. At this time, the limiting sidewall 1021 of the limiting recess 102 will abut against the outer surface of the water pump assembly 20. The abutment between the limiting sidewall 1021 and the water pump assembly 20 will generate a reverse force on the water pump assembly 20, pushing the water pump assembly 20 back to its initial, stable working position.

[0081] In this way, when the user accidentally applies a radial thrust to the pusher 202, causing the first limiter 103 to release its limit on the second limiter 201, as long as the user stops pulling the water pump assembly 20, the water pump assembly 20 will not remain stuck in the wrong position or tip over due to the thrust. Instead, it will automatically reset to its initial position under the abutment of the limiter sidewall 1021, thereby improving the operational fault tolerance and user experience of disassembling the water pump assembly 20.

[0082] like Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the pump assembly 20 includes a sliding fit portion 204. The sliding fit portion 204 is connected to the side wall and bottom wall of the pump assembly 20 facing the reservoir 10 by an arc transition. That is, the sliding fit portion 204 connects the side wall surface and the bottom wall surface of the pump assembly 20 through its own smooth arc surface.

[0083] When the pusher 202 is subjected to a pushing force, or during the process of the water pump assembly 20 resetting to the working position, the sliding mating part 204 can slide along the side wall of the liquid storage tank 10.

[0084] When the user applies a radial pushing force to the pushing part 202, the water pump assembly 20 will deflect to a certain extent. At this time, the sliding fit part 204 contacts the surface of the side wall of the liquid storage tank 10 and can slide smoothly upward along its surface. The arc-shaped sliding fit part 204 reduces the frictional resistance and motion interference during the sliding process of the water pump assembly 20, making the user's pushing operation of the water pump assembly 20 easier and smoother.

[0085] Furthermore, during the process of the water pump assembly 20 automatically resetting to its working position due to the aforementioned reset function, the sliding engagement portion 204 also slides downward along the inner surface of the side wall of the liquid storage tank 10. The arc-shaped contour of the sliding engagement portion 204 can guide the water pump assembly 20 to accurately return to its initial working position and adaptively correct for possible minor positional deviations, so that the bottom of the water pump assembly 20 falls into the limiting recess 102, and the second limiting portion 201 at the top and the first limiting portion 103 resume their engagement relationship, thereby achieving consistent reset.

[0086] Thus, by providing a sliding engagement part 204, the water pump assembly 20 optimizes the user's operating feel when pushing the water pump assembly 20, reduces the possibility of the water pump assembly 20 getting stuck on the side wall of the liquid storage tank 10, and further improves the accuracy of the water pump assembly 20's reset process.

[0087] like Figure 6 and Figure 7 As shown, in some embodiments, the number of second limiting portions 201 is at least two, and at least two second limiting portions 201 are arranged at intervals along the circumferential direction.

[0088] By arranging at least two second limiting parts 201 circumferentially along the humidification device 1, multiple limiting points can be formed in the circumferential direction of the humidification device 1, so as to form a more balanced and stable cooperation relationship with the first limiting part 103 at the top of the liquid storage tank 10.

[0089] During disassembly, when the user applies radial thrust to the pushing part 202, the multiple spaced second limiting parts 201 can simultaneously disengage from the first limiting part 103, reducing the possible skewing or jamming caused by unilateral disengagement.

[0090] In some embodiments, such as Figure 8 As shown, the liquid storage tank 10 includes an elastic buckle 105. The elastic buckle 105 has a certain elastic deformation capability, and can undergo temporary displacement or shape change under the action of external force, and return to its initial state after the external force is removed.

[0091] In some embodiments, such as Figure 6 and Figure 7 As shown, the pushing part 202 includes an engaging part 2021 that can engage with the elastic buckle 105. The engaging part 2021 can be a groove structure formed on the side wall of the pushing part 202.

[0092] In some embodiments, the liquid storage tank 10 includes an assembly portion 1032 disposed on the first limiting portion 103. The assembly portion 1032 extends in the height direction and is used to assemble with the water receiving tray 30.

[0093] The assembly part 1032 forms clearance notches 1032a at both ends along the circumferential direction and extends into the interior of the storage tank 10 at the clearance notches 1032a. The elastic buckle 105 is formed on the part of the assembly part 1032 that extends into the storage tank 10, so that the engaging part 2021 on the side wall of the water pump assembly 20 can face the elastic buckle 105 and be mutually limited by the elastic buckle 105.

[0094] like Figure 8 As shown, the elastic buckle 105 can be a cantilever structure formed by partially hollowing out the assembly part 1032. The elastic buckle 105 may be provided with protrusions to adapt to the engaging part 2021 and form a limiting fit. The assembly part 1032 may be made of plastic material, thereby giving the elastic buckle 105 deformable properties.

[0095] The clearance notch 1032a provides the necessary accommodating space for the deformation of the elastic buckle 105 and the limiting cooperation of the engaging part 2021, thereby enabling the engagement and disengagement of the elastic buckle 105 and the engaging part 2021 to proceed smoothly.

[0096] Thus, the elastic buckle 105 can be positioned opposite the engaging portion 2021 on the side wall of the water pump assembly 20 via the mounting portion 1032. When the water pump assembly 20 is in the working position, the elastic buckle 105 can engage and lock with the engaging portion 2021, providing auxiliary fixation for the water pump assembly 20. When disassembling the water pump assembly 20, applying a radial thrust to the pushing portion 202 will cause the engaging portion 2021 to compress and deform the elastic buckle 105, thereby releasing the engagement.

[0097] like Figure 5 , Figure 6 and Figure 8 As shown, in some embodiments, the water pump assembly 20 includes a water inlet 205.

[0098] The water inlet 205 is in fluid communication with the liquid storage chamber 101 and is used to introduce liquid into the water pump to achieve the water suction function. At least a portion of the water inlet 205 extends downward and is exposed in the limiting recess 102. Since the limiting recess 102 is a recessed area on the bottom wall of the liquid storage tank 10, when the liquid level in the liquid storage tank 10 drops, the humidifying liquid will collect and remain in the limiting recess 102. By being exposed in the limiting recess 102, the water inlet 205 can continuously contact the liquid collected in the recessed area.

[0099] In this way, the water pump assembly 20 can still draw water when the liquid level in the storage tank 10 is low, reducing the risk of air intake in the water pump assembly 20 and improving the working efficiency and reliability of the water pump assembly 20.

[0100] In some embodiments, the water inlet 205 includes a plurality of water inlets 2051. At least some of the water inlets 2051 have their lower edges higher than or flush with the bottom wall of the liquid storage tank 10, and at least one water inlet 2051 has its lower edge lower than the bottom wall of the liquid storage tank 10.

[0101] Multiple inlets 2051 are located at different water levels, so that the inlet 2051 at the lower water level can preferentially draw in the liquid that gathers at the bottom of the limiting recess 102. Even under extremely low liquid level conditions, the water pump assembly 20 can still perform the water suction function, reducing air intake.

[0102] The higher-positioned inlet 2051 (the inlet 2051 above the bottom wall of the storage tank 10) allows for water intake when the storage tank 10 is at the normal liquid level, ensuring sufficient liquid intake for the pump assembly 20. Simultaneously, the higher-positioned inlet avoids scale buildup at the bottom of the storage tank 10, drawing in the cleaner middle layer of liquid, thus reducing the risk of wear or blockage of the pump assembly 20 due to the intake of sediment.

[0103] Thus, the combination of multi-stage inlets 2051 not only ensures the reliability of the pump assembly 20 at low liquid levels, but also improves the water intake efficiency of the pump assembly 20 when it is at a normal water level in the storage tank 10, while also taking into account the anti-clogging function.

[0104] In some embodiments, such as Figure 9As shown, the humidification device 1 also includes a water receiving tray 30 and a humidification component 40. The humidification component 40 is detachably mounted on the water receiving tray 30. The humidification component 40 includes a water supply pipe 401, which passes through a pre-set through hole or interface structure on the water receiving tray 30 and communicates with the water pump assembly 20.

[0105] The humidification component 40 may include a wettable substrate, which may be a filter material made of hydrophilic polymer composite material or natural / synthetic fiber fabric. The surface of the wettable substrate may be treated with a nano-coating or gradient porosity to optimize capillary water absorption performance. The wettable substrate forms an air-water contact interface with a high specific surface area through a multi-layer composite or three-dimensional honeycomb structure.

[0106] To maintain the morphological stability of the wettable substrate in a wetted state, a support frame is also embedded in the substrate. The support frame can be made of water-resistant plastic or metal and is used to resist the deformation that may occur in the wettable substrate under hydration softening and airflow impact.

[0107] In addition, the humidification component 40 can adopt a modular assembly structure composed of standard wettable substrate units, which not only facilitates manufacturing and user replacement, but also flexibly adapts to humidification devices 1 with different capacities and air duct requirements.

[0108] One end of the water supply pipe 401 can be detachably connected to the water outlet of the water pump assembly 20 via a quick connector, and the other end extends into the interior of the humidification assembly 40 and communicates with the liquid in the water distribution pan formed by the support frame, so as to evenly distribute the humidification liquid pressurized and delivered by the water pump assembly 20 to the wettable substrate.

[0109] The water supply pipe 401 can be made of flexible or rigid pipe. A sealing ring or waterproof structure can be provided at the through hole of the water receiving tray 30 to prevent liquid from leaking from the connection of the water supply pipe 401 and reducing the water supply efficiency of the water pump assembly 20.

[0110] The water tray 30 can be detachably attached above the liquid storage tank 10 to support the humidification component 40 and collect the liquid overflowing from the humidification component 40. The bottom of the water tray 30 may be provided with a flow guiding structure to guide the collected liquid back into the liquid storage chamber 101 of the liquid storage tank 10, so as to realize the recycling of humidification liquid.

[0111] In some embodiments, such as Figure 9 , Figure 10 and Figure 11 As shown, the water receiving tray 30 includes a third limiting part 301. At least a portion of the water pump assembly 20 extends into the interior of the third limiting part 301 along the height direction, and the third limiting part 301 limits the water pump assembly 20 in the circumferential direction.

[0112] The third limiting part 301 can be a notch formed in the water receiving tray 30, extending to the edge of the water receiving tray 30. The pushing part 202 of the water pump assembly 20 extends into the interior of the third limiting part 301. Through the cooperation between the inner wall of the third limiting part 301 and the outer surface of the pushing part 202, the water receiving tray 30 limits the circumferential rotation of the water pump assembly 20, thereby improving the alignment and sealing reliability of the connection between the outlet end of the water pump assembly 20 and the water supply pipe 401.

[0113] Thus, the third limiting part 301 and the limiting recess 102 together constitute a coordinated limiting of the water pump assembly 20 in the vertical direction, further enhancing the installation stability and vibration resistance of the water pump assembly 20 in the liquid storage tank 10.

[0114] In some embodiments, such as Figure 6 , Figure 7 and Figure 9 As shown, the water pump assembly 20 includes a power supply interface 209 extending from the third limiting part 301.

[0115] With the water pump assembly 20 installed in the working position, the power supply interface 209 extends upward along the height direction above the top of the third limiting part 301, thereby exposing the space above the water receiving tray 30 to connect with the power supply terminal of the humidifying device 1 located above the water receiving tray 30.

[0116] The power supply interface 209 is designed for easy connection to the power supply terminal to improve the assembly efficiency of the water pump assembly 20. Simultaneously, the position of the power supply interface 209 above the water tray 30 reduces the risk of immersion of the power supply interface when liquid accumulates in the water tray 30, thus enhancing the electrical safety of the humidification device 1.

[0117] like Figure 4 As shown, in some embodiments, the free end of the first limiting portion 103 extends along the height direction to form an assembly portion 1032, and the water receiving tray 30 overlaps the assembly portion 1032.

[0118] The assembly part 1032 allows the water tray 30 to be stably mounted above the liquid storage tank 10, and its weight is transferred to the tank body of the liquid storage tank 10 through the assembly part 1032. The assembly part 1032 can also constrain the movement of the water tray 30 in the horizontal plane, thereby improving the structural stability of the humidification device 1.

[0119] In some embodiments, such as Figure 9 , Figure 10 and Figure 11 As shown, the water receiving tray 30 includes a receiving tank 302. The receiving tank 302 is used to hold scale inhibitors.

[0120] Scale inhibitors can be in the form of solid particles, solid blocks, or gels. They can be chemical scale inhibitors with scale-removing properties, such as silica phosphate crystals, food-grade citric acid, and composite phosphate gels.

[0121] The humidifying liquid overflowing from the humidifying component 40 can converge into the receiving tank 302 and interact with the scale inhibitor in the receiving tank 302, at least part of the scale inhibitor is dissolved to form a solution with scale inhibition function.

[0122] The receiving tank 302 is provided with a drain gap 3021. The drain gap 3021 faces the first side wall 206 of the water pump assembly 20, and there is a preset distance between the drain gap 3021 and the first side wall 206.

[0123] The drain gap 3021 allows the solution containing scale inhibitors to slowly flow out of the receiving tank 302 and flow along the surface of the first sidewall 206 under gravity. The scale inhibitor liquid is guided back to the storage chamber 101 of the storage tank 10, thereby entering the liquid circulation path of the humidification device 1.

[0124] Through this cycle, the scale inhibitor can continuously act on the entire liquid circuit, achieving scale protection for the water pump assembly 20, humidification assembly 40 and liquid storage tank 10, inhibiting the formation and accumulation of scale, maintaining the operating efficiency of the humidification device 1 and extending its service life.

[0125] like Figure 2 and Figure 9 As shown, in some embodiments, the first sidewall 206 is inclined relative to the height direction. The inclined structure of the first sidewall 206 can guide and buffer the liquid flowing along its surface, reduce the noise generated by the impact during the liquid flow, and thus improve the quietness of the humidification device 1 during operation.

[0126] In addition, the inclined design of the first sidewall 206 allows the liquid to flow out of the surface of the first sidewall 206 under the action of gravity, reducing the residual dripping liquid and scale deposition after evaporation on the surface of the water pump assembly 20, which helps to keep the surface of the water pump assembly 20 clean.

[0127] like Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments, the receiving tank 302 includes a second sidewall 3022 opposite to the first sidewall 206, and a drain gap 3021 is disposed on the second sidewall 3022 and extends through to the bottom wall of the receiving tank 302.

[0128] Since the drain gap 3021 is located on the second side wall 3022 and extends to the bottom wall, the outflowing liquid can be guided to the surface of the first side wall 206 and flow along the inclined surface of the first side wall 206, further improving the guidance of the liquid flowing out from the drain gap 3021.

[0129] The drain gap 3021 extends to the bottom wall of the receiving tank 302, ensuring that it is located at the lowest point of the liquid within the tank. Under gravity, the liquid in the receiving tank 302 can be drained as much as possible through the drain gap 3021, thereby reducing liquid residue. This reduces the probability of stagnant water accumulating in the receiving tank 302 and forming scale after evaporation, and also improves the efficiency of scale inhibitors.

[0130] like Figure 2 and Figure 9 As shown, in some embodiments, the bottom wall of the receiving tank 302 is inclined relative to the horizontal plane, and the drain gap 3021 is connected to the end of the bottom wall of the receiving tank 302 near the liquid storage tank 10.

[0131] The inclined bottom wall of the receiving tank 302 allows the liquid inside to flow naturally to the drain gap 3021 under gravity and be discharged in a concentrated manner. This further reduces the amount of liquid residue in the receiving tank 302 and lowers the risk of evaporation and scale buildup caused by standing water.

[0132] In some embodiments, such as Figure 9 As shown, the water receiving tray 30 is also equipped with an anti-overflow baffle 303.

[0133] The overflow baffle 303 extends along the height direction, and the upper edge of the overflow baffle 303 is higher than the opening of the receiving tank 302, so that the liquid overflowing from the humidification component 40 gathers into the receiving tank 302.

[0134] The overflow baffle 303 can surround or be located around the periphery of the receiving tank 302. The upper edge of the overflow baffle 303 is higher than the opening of the receiving tank 302, which can prevent the liquid overflowing from the humidification component 40 from spreading to areas outside the receiving tank 302, so that the liquid gathers and is guided to the opening area of ​​the receiving tank 302, thereby allowing the overflow liquid to be collected and fully contacted with the scale inhibitor in the receiving tank 302.

[0135] In addition, the anti-overflow baffle 303 reduces the ineffective accumulation of liquid in other areas of the water receiving tray 30 and improves the return efficiency of liquid overflowing from the humidification component 40.

[0136] In some embodiments, such as Figure 5 As shown, the water pump assembly 20 includes a housing 207 and a water level detection assembly 208 disposed within the housing 207.

[0137] The housing 207 includes a receiving cavity 2071, in which a water pump can be installed. A second limiting part 201 is provided on the housing 207, and the housing 207 is detachable from the liquid storage cavity 101.

[0138] The water level detection component 208 is integrated inside the housing 207. The sensor of the water level detection component 208 can be connected to the liquid storage chamber 101 and the water inlet 205 to detect the water level status in the liquid storage tank 10, thereby realizing the functions of water shortage protection and liquid level monitoring.

[0139] 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.
