Description

Technical Field

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

[0002] A humidifier typically consists of a water tank, a water trough, and a float that controls the water level in the trough. The float is located inside the trough, which holds water and houses an atomizing plate located at the bottom to atomize the water and produce moisture. Water is added to the trough from the tank via a drain valve. When the water level rises, the float rises due to buoyancy, closing the drain valve and stopping the tank from replenishing water. When the water level drops, the float falls due to gravity, reopening the drain valve and allowing the tank to continue replenishing water, thus achieving automatic water level regulation.

[0003] However, when the water level in the tank is low, the residual water disperses and is difficult to flow steadily and continuously to the area where the atomizing plate is located, resulting in insufficient water supply to the atomizing plate, or even local dry burning, which reduces the humidifier's reliability and service life. Utility Model Content

[0004] This application discloses a humidifier. By setting the water guiding surface and water inlet surface at the bottom of the water tank, the residual water in the water tank at low water level can be guided to converge towards the atomizing plate, so that the atomizing plate can continuously obtain a stable water supply, thereby improving the reliability of the humidifier.

[0005] This application provides a humidifier, which includes a water tank with a drainage channel; a base, wherein the water tank is detachably disposed on the base, and the base includes a water trough for receiving water discharged from the drainage channel. The bottom wall of the water trough includes a water guiding surface and a drainage surface connected to each other. The drainage surface is provided with a drain outlet for injecting water into the atomizing plate. The drainage surface is not higher than the water guiding surface, and at least a portion of the water guiding surface guides the water discharged from the drainage channel to the drainage surface.

[0006] In one possible implementation, the water guiding surface includes a water guiding end and a water outlet end with a height difference, the water outlet end being farther away from the water tank than the water guiding end, and the height of the water outlet end being not lower than the drainage surface.

[0007] In one possible implementation, at least a portion of the water guiding surface extends at an angle relative to the horizontal plane, the water guiding surface including an outlet end remote from the water tank, the height of the outlet end being not lower than the drainage surface.

[0008] In one possible implementation, the bottom wall of the water tank further includes a smooth transition surface, through which the water guiding surface and the drainage surface are connected.

[0009] In one possible implementation, the drain outlet and the water guiding surface are at a predetermined distance.

[0010] In one possible implementation, the drain outlet is located in the central region of the drain surface.

[0011] In one possible implementation, a mist exhaust channel is formed inside the water tank, which is used to discharge the water mist generated by the atomizing plate from the humidifier, and the drain outlet is located within the vertical projection range of the mist exhaust channel.

[0012] In one possible implementation, the humidifier further includes:

[0013] A drain valve is installed in the drain channel;

[0014] A floating drive assembly is disposed within the water tank and is used to drive the drain valve to open or close the drain channel. At least a portion of the floating drive assembly is disposed corresponding to the water guide surface so that the water flow discharged from the drain valve is guided to the drain surface through the water guide surface.

[0015] In one possible implementation, the floating drive component includes:

[0016] A pivot seat is provided on the water guide surface;

[0017] A float is rotatably mounted on the pivot seat. One end of the float is a float portion for rising and falling with the liquid level in the water tank, and the other end of the float is an actuating portion for opening or closing the drain valve. The float portion and the actuating portion are located on opposite sides of the pivot seat.

[0018] The float part has a mating surface facing the water guiding surface. When the float part is in a sinking state, the mating surface and at least part of the water guiding surface are inclined relative to the horizontal plane, and the mating surface and the water guiding surface form an angle θ1, where 0°≤θ1≤3°.

[0019] In one possible implementation, along the horizontal direction, the mating surface includes a first end away from the pivot seat and a second end close to the pivot seat, wherein when the float is in a floating state, the second end is closer to the water guide surface than the first end;

[0020] At least a portion of the water guiding surface extends at an angle relative to the horizontal plane, the water guiding surface includes a water guiding end and a water outlet end having a height difference, the first end of the mating surface is closer to the water outlet end than the second end of the mating surface, and the second end of the mating surface is closer to the water guiding end than the first end of the mating surface.

[0021] In one possible implementation, the water guiding surface includes a first water guiding part and a second water guiding part connected together, the first water guiding part corresponding to the float part, the first water guiding part being inclined relative to the horizontal plane, and the first water guiding part being higher than the drainage surface;

[0022] The second water guiding part corresponds to the trigger part. The second water guiding part is inclined relative to the horizontal plane or parallel to the horizontal plane, and the second water guiding part is higher than the first water guiding part.

[0023] In one possible implementation, the humidifier further includes:

[0024] A light-emitting element is disposed on the base and located outside the water tank;

[0025] The water tank also includes:

[0026] A light-transmitting portion protrudes from the drainage surface and corresponds to the light-emitting element. The height of the light-transmitting portion is not lower than the height of the outlet of the drainage channel. A mist-expelling channel is formed inside the water tank to discharge the water mist generated by the atomizing plate from the humidifier. The light-transmitting portion is located within the vertical projection range of the mist-expelling channel.

[0027] In one possible implementation, a guide post is provided on the drainage surface, and a magnetic element is sleeved on the guide post.

[0028] In one possible implementation, the magnetic component can reciprocate along the guide post as the water level in the tank changes, and when the magnetic component is in its extreme position, it can be accommodated in the recess of the drainage surface.

[0029] The humidifier also includes a Hall sensor, which is disposed on the base and located outside the water tank. The Hall sensor is magnetically coupled to the magnetic component to detect the water level in the water tank.

[0030] In one possible implementation, the seat has a receiving cavity, the water tank is detachably disposed within the receiving cavity, and there is a predetermined distance between the water tank and the cavity wall.

[0031] In one possible implementation, the bottom wall of the water tank is provided with reinforcing ribs on the surface facing the base, and at least part of the reinforcing ribs are arranged around the drain outlet.

[0032] The humidifier provided in this embodiment has a water tank bottom wall comprising a water guiding surface and a draining surface. The height difference between the water guiding and draining surfaces naturally guides the water flow, allowing the humidifying water to converge more quickly and concentratedly at the drain outlet on the draining surface. Especially when the water tank is operating at a low water level, it can guide as much residual water as possible to the drain outlet, reducing the risk of dry burning of the atomizing element due to lack of water. Simultaneously, the combination of the water guiding and draining surfaces improves the overall utilization efficiency of the water flow within the tank, reduces the amount of residual water, helps inhibit microbial growth caused by stagnant water, and improves the hygiene level of the humidifier.

Detailed Implementation

[0050] 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.

[0052] 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.

Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0054] 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.

[0055] The water tank in a humidifier stores water and houses an atomizing plate. The tank typically has a flat bottom, and the atomizing plate is mounted on this bottom wall. A float controls the water level in the tank. The float rises and falls with the water level in the tank, opening or closing the valve to maintain the water level within a certain range.

[0056] However, when the water level in the tank is low, because the bottom wall is flat, the remaining small amount of water cannot flow to the location of the atomizing plate. This can lead to insufficient water supply to the atomizing plate, resulting in unstable atomization or even localized dry burning.

[0057] Based on this, this application proposes a humidifier that, by improving the bottom structure of the water tank, can guide the residual water in the water tank to converge towards the atomizing plate when the water level is low, so that the atomizing plate can continuously obtain a stable water supply, thereby improving the reliability of the humidifier.

[0058] Figures 1 to 3 As shown, this application embodiment provides a humidifier 1, which can be used for air humidification in home or office environments. The humidifier 1 includes a water tank 10 and a base 20. The water tank 10 is used to store humidification water, and the base 20 can be used to install an atomizing plate to achieve the humidification function.

[0059] like Figure 3As shown, the water tank 10 may be provided with a drain channel 101. A drain valve 102 may be provided at the drain channel 101 to control the amount of water drained from the water tank 10 to the water tank 21 inside the seat 20. The drain valve 102 may be used in conjunction with a float structure or other automatic valve structure to replenish the humidifying water stored in the water tank 10 to the water tank 21 and flow from the water tank 21 to the atomizing plate.

[0060] like Figure 2 As shown, the base 20 serves as the main support structure for the humidifier 1. The water tank 10 is detachably mounted above the base 20, facilitating convenient refilling. The base 20 contains a removable water trough 21, which receives humidifying water flowing from the drain channel 101 of the water tank 10. The water trough 21 can be separated from the base 20 for individual cleaning. Alternatively, the water trough 21 can be fixedly connected to the base 20 or integrally formed with it to further enhance its structural strength. Figure 4 As shown, a drain outlet 2121 is provided in the water tank 21, which corresponds to the atomizing plate provided on the base 20, so as to concentrate and discharge the water in the water tank 21 to the atomizing plate. The atomizing plate is used to convert the humidifying water into water mist, thereby realizing the humidification function of the humidifier 1.

[0061] like Figure 4 , Figure 5 and Figure 6 As shown, the bottom wall of the water tank 21 includes a water guiding surface 211 and a drainage surface 212 connected to each other. The drainage surface 212 is not higher than the water guiding surface 211, and the drain outlet 2121 is located on the drainage surface 212. The overall height of the drainage surface 212 is not higher than the water guiding surface 211, meaning any point within the drainage surface 212 can be lower than the water guiding surface 211, creating a height difference between them. This allows the humidifying water flowing through the water guiding surface 211 to naturally flow towards the drainage surface 212 using the force of gravity, and then converge at the drain outlet 2121. The non-planar design of the bottom wall of the water tank 21 guides and concentrates the humidifying water, improving the stability of the water supply to the atomizing plate when the water tank 21 is at a low water level.

[0062] It is understood that the connection between the water guiding surface 211 and the drainage surface 212 is such that the water guiding surface 211 and the drainage surface 212 can be integrally formed and smoothly connected. There are no protruding structures or other structural obstructions at the connection between the two, so that the water can flow from the water guiding surface 211 to the drainage surface 212 without disturbance.

[0063] like Figure 5As shown, the water guiding surface 211 is used to guide the direction of water flow. The water guiding surface 211 is connected to the drainage surface 212. Water flowing out of the drainage channel 101 first reaches the water guiding surface 211, and through the inclined or curved surface structure of the water guiding surface 211, the water flow is guided to the drainage surface 212. The water guiding surface 211 can be a sloping surface, a curved surface with curvature, or other structures suitable for guiding flow.

[0064] The drainage surface 212 can be a flat or slightly concave surface, and the drainage outlet 2121 can be located at the lowest point or the center of the drainage surface 212, which facilitates the water flow to be collected and concentrated and transported to the drainage outlet 2121, and then enters the atomizing plate.

[0065] Thus, in this embodiment, the bottom wall of the water tank 21 of the humidifier 1 includes a water guiding surface 211 and a draining surface 212. The height difference between the water guiding surface 211 and the draining surface 212 creates a natural guide for the water flow, allowing the humidifying water to converge more quickly and centrally to the drain outlet 2121 on the draining surface 212. Especially when the water tank 21 is operating at a low water level, the water guiding surface 211 can guide as much residual water as possible from the water tank 21 to the drain outlet 2121, reducing the risk of dry burning of the atomizing plate due to lack of water. Simultaneously, the combined use of the water guiding surface 211 and the draining surface 212 improves the overall utilization efficiency of the water flow within the water tank 21, reduces the amount of residual water in the water tank 21, helps inhibit the growth of microorganisms caused by stagnant water, and improves the hygiene level of the humidifier 1.

[0066] like Figure 7 As shown, in some embodiments, the water guiding surface 211 includes a water guiding end 2111 and a water outlet end 2112 with a height difference. The water outlet end 2112 is farther away from the water tank 10 than the water guiding end 2111, and the height of the water outlet end 2112 is not lower than the drainage surface 212.

[0067] The water guiding surface 211 can be set as an inclined plane with a certain height difference or a curved surface with curvature. The water guiding surface 211 can include a higher water guiding end 2111 and a lower water outlet end 2112. Here, "high" and "low" are relative to the relative spatial position of the humidifier 1 in its normal use and placement state, that is, the vertical direction perpendicular to the horizontal plane.

[0068] The water guide end 2111 of the water guide surface 211 can be located on one side near the drain channel 101 of the water tank 10 to receive the humidifying water flowing in from the water tank 10. The water outlet end 2112 of the water guide end 2111 is further away from the water tank 10 than the water guide end 2111 and is adjacent to the drain surface 212.

[0069] The outlet end 2112 is positioned at a height no lower than the drainage surface 212. That is, the vertical position of the outlet end 2112 is flush with or slightly higher than the drainage surface 212, allowing the water flowing from the outlet end 2112 to smoothly flow into the drainage surface 212 under gravity, reducing stagnation during this process. Through the height difference formed along the inclined or curved surface between the guide end 2111 and the outlet end 2112, the water flowing from the water tank 10 can flow naturally along the guide surface 211, achieving directional delivery of the water from the drainage channel 101 to the drain outlet 2121 supplying water to the atomizing plate.

[0070] Especially when the water tank 21 is at a low water level, a small amount of water can be diverted to the drain outlet 2121, which helps maintain the normal operation of the atomizing plate under low water level conditions in the water tank 21.

[0071] like Figure 7 As shown, in some embodiments, at least a portion of the water guiding surface 211 extends at an angle relative to the horizontal plane, and the water guiding surface 211 includes a water outlet end 2112 away from the water tank 10, the height of the water outlet end 2112 being not lower than the drainage surface 212.

[0072] At least part of the water guiding surface 211 is constructed to extend at an inclined angle relative to the horizontal plane, and the water outlet 2112 can be the end of the water guiding surface 211 further away from the water tank 10, that is, the water outlet 2112 can be the lowest point of the water guiding surface 211, thereby using gravity to guide the water flow from the drainage channel 101, causing the water flow to flow along the inclined water guiding surface 211 to the water outlet 2112.

[0073] The height of the water outlet 2112 is set to be no lower than the drainage surface 212, so that the water flowing out of the water outlet 2112 can quickly and smoothly transition to the drainage surface 212 and finally converge to the drain outlet 2121. The inclined structure of the water guiding surface 211 not only improves the efficiency of water flow guidance, but also reduces water flow resistance and improves the water supply reliability of the atomizing plate under low water level conditions.

[0074] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the water tank 21 further includes a smooth transition surface 213. The smooth transition surface 213 is connected to the water guiding surface 211 and the drainage surface 212 respectively, that is, the water guiding surface 211 and the drainage surface 212 are connected to each other through the smooth transition surface 213.

[0075] The smooth transition surface 213 may include a smooth arc or curved surface to allow water to flow naturally from the guide surface 211 to the drain surface 212. The guide surface 211 and the drain surface 212 are connected by the smooth transition surface 213, which prevents sharp corners or abrupt structural changes between them. The smooth transition surface 213 buffers the water flowing out of the guide surface 211, allowing the water to flow smoothly into the drain surface 212 and then converge at the drain outlet 2121.

[0076] Furthermore, the water flow from the guide surface 211 through the smooth transition surface 213 to the drain surface 212 is less prone to noise, improving the user comfort of the humidifier 1. At the same time, the smooth transition surface 213 also reduces the risk of impurities accumulating in the groove, making it easier for users to clean and maintain the water tank 21.

[0077] In some embodiments, the drain outlet 2121 and the water guide surface 211 have a preset distance.

[0078] The distance between the drain outlet 2121 and the water guide surface 211 is preset, which helps to reduce the flow velocity and stabilize the flow direction of the water flowing out of the water guide surface 211, and reduces the eddies that may occur during the water injection process of the drain outlet 2121.

[0079] It is understandable that if the distance between the drain outlet 2121 and the water guide surface 211 is too close, the water flowing out of the water guide surface 211 may be too fast and directly impact the drain outlet 2121, potentially causing eddies at the drain outlet 2121 and increasing noise. Specifically, in the horizontal direction, the water guide surface 211 can be at a preset distance L1 from the center of the drain outlet 2121, where L1 > 50mm. For example, L1 can be 51mm, 60mm, 70mm, or 80mm.

[0080] In addition, by controlling the preset distance between the drain outlet 2121 and the water guide surface 211, a certain amount of water can be temporarily stored on the drain surface 212, especially when the water tank 21 is in a low water level state, thereby providing a continuous water source for the atomizing plate.

[0081] In some embodiments, the drain outlet 2121 is located in the central region of the drain surface 212.

[0082] Placing the drain outlet 2121 at the geometric center of the drainage surface 212 facilitates the convergence of water flow from the drainage surface 212 to the drain outlet 2121. The central location of the drain outlet 2121 enables a balanced distribution of water within the tank 21, reducing the risk of localized water accumulation caused by water flow biased to one side of the drainage surface 212 and insufficient water flow at the drain outlet 2121.

[0083] like Figure 3As shown, in some embodiments, the humidifier 1 further includes a drain valve 102. The drain valve 102 is disposed within the drain channel 101.

[0084] A drain valve 102 is located in the drain channel 101 at the bottom of the water tank 10 and is used to control the amount of water supplied from the water tank 10 to the water trough 21. The drain valve 102 can be a float-type structure or an automatic valve such as a solenoid valve to achieve automatic opening or closing.

[0085] like Figure 3 As shown, in some embodiments, the humidifier 1 further includes a floating drive assembly 30. The floating drive assembly 30 is disposed within the water tank 21 and is used to drive the drain valve 102 to open or close the drain channel 101.

[0086] like Figure 3 As shown, the floating drive assembly 30 includes a pivot seat 302 and a float 300. The pivot seat 302 is fixedly disposed above the water guide surface 211. The float 300 is rotatably mounted on the pivot seat 302 via a pivot shaft. One end of the float 300 is a float part 301, which can move up and down with the rise and fall of the water level in the water tank 21. The other end of the float 300 is an actuating part 303, used to open or close the drain valve 102 when the water level changes. The float part 301 and the actuating part 303 are located on both sides of the pivot seat 302, forming a lever structure to realize automatic opening and closing control of the drain valve 102 according to the water level change.

[0087] like Figure 3 As shown, at least a portion of the floating drive assembly 30 is disposed corresponding to the water guide surface 211 so that the water flow discharged from the drain valve 102 is guided to the drain surface 212 through the water guide surface 211.

[0088] Specifically, the horizontal projection of the floating drive assembly 30 is at least partially located within the guide surface 211. This causes the water discharged from the drain valve 102 to first flow to the guide surface 211, and then be guided to the drain surface 212 by the inclined or curved structure of the guide surface 211, before converging into the drain outlet 2121. The corresponding arrangement of the floating drive assembly 30 and the guide surface 211 provides a guiding path for the water flow during the initial replenishment phase. The inclined or curved structure of the guide surface 211 reduces noise that may be caused by water flow impact, facilitating the rapid and smooth distribution of water to the drain surface 212 and improving replenishment efficiency.

[0089] In some embodiments, such as Figure 8 As shown, the lower surface of the float part 301 is a mating surface 3011, which faces the guide water surface 211. The mating surface 3011 is set as an inclined surface relative to the horizontal plane. Figure 9As shown, when the float part 301 is in a submerged state (i.e., the water tank 21 is in a low water level state), the mating surface 3011 and at least part of the water guiding surface 211 are inclined relative to the horizontal plane, and an angle θ1 is formed between them.

[0090] The angle formed between the mating surface 3011 and the water guiding surface 211 can prevent the float part 301 from sticking to the water guiding surface 211 when the water tank 21 is at a low water level.

[0091] It should be noted that if the mating surface 3011 and the water guiding surface 211 are in contact, the residual water between them may generate surface tension, causing a liquid bridge to form between the float part 301 and the water guiding surface 211, resulting in an adsorption force. This adsorption can cause the float part 301 to be "sucked" or "supported" by the water. When the water level in the water tank 21 drops to a low level, this adhesion force may prevent the float part 301 from sinking normally under the action of gravity, thus preventing the trigger part 303 from opening the drain valve 102. If the drain valve 102 cannot be opened in time, the water tank 21 will not be able to receive water, which may lead to insufficient water supply or even dry burning of the atomizing plate.

[0092] In some embodiments, when the float part 301 is in a submerged state, the included angle θ1 between the mating surface 3011 and the water guiding surface 211 satisfies: 0°≤θ1≤3°.

[0093] When θ1 ≥ 0°, the risk of the mating surface 3011 and the water guiding surface 211 coming into contact is reduced, and the adsorption effect caused by the surface tension generated by the residual water between them is weakened, so that the float part 301 can still operate reliably under low water level conditions. When θ1 = 0°, the mating surface 3011 and the water guiding surface 211 are parallel to each other, which can minimize the sinking displacement loss of the float part 301, thereby helping the actuating part 303 to obtain a larger operating stroke.

[0094] With θ1 ≤ 3°, the sinking displacement loss of the float part 301 can be minimized while avoiding contact between the mating surface 3011 and the water guiding surface 211. This prevents the surface tension of residual water from adsorbing it and allows the actuating part 303 to obtain sufficient stroke to reliably open the drain valve 102, achieving timely and stable water replenishment at low water levels.

[0095] In some embodiments, such as Figure 8 and Figure 10 As shown, along the horizontal direction, the mating surface 3011 includes a first end 3011a away from the pivot seat 302 and a second end 3011b close to the pivot seat 302. When the float part 301 is in a floating state, the second end 3011b is closer to the water guide surface 211 than the first end 3011a.

[0096] When the float part 301 is in a floating state, the second end 3011b of the mating surface 3011 extends inclined towards the bottom wall of the water tank 21, so that the mating surface 3011 is in an inclined shape when floating.

[0097] It is understandable that the inclined mating surface 3011 can contact the humidifying water in the water tank 21 with a larger area. If the mating surface 3011 is constructed as a plane, the mating surface 3011 is parallel to the horizontal plane when the float part 301 is in a floating state. In this case, when the water level in the water tank 21 is low, the float part 301 is immersed in the water to a shallow depth, its contact area with the humidifying water is limited, and the buoyancy generated by the water on the float part 301 is small, which may cause the float part 301 to fail to float up in time or fully, thereby affecting the normal closing of the drain valve 102.

[0098] In contrast, in this embodiment, the mating surface 3011 of the float portion 301 is inclined relative to the horizontal plane. Under the same low water level conditions, this inclined orientation changes the immersion shape of the float, causing the local immersion depth of its lower side (second end 3011b) to be greater than the immersion depth designed for a horizontal orientation. This allows the float portion 301 to displace more water volume, thereby obtaining greater buoyancy than in a horizontal orientation, ensuring that the float portion 301 can float sensitively even at low water levels.

[0099] like Figure 10 As shown, in some embodiments, at least a portion of the water guiding surface 211 extends at an angle relative to the horizontal plane. The water guiding surface 211 includes a water guiding end 2111 and a water outlet end 2112 with a height difference. The first end 3011a of the mating surface 3011 is close to the water outlet end 2112, and the second end 3011b of the mating surface 3011 is close to the water guiding end 2111.

[0100] Along the horizontal direction, the mating surface 3011 includes a first end 3011a away from the pivot seat 302 and a second end 3011b close to the pivot seat 302. When the float part 301 is in a floating state, due to the lever principle and the weight of the float part 301 itself, the second end 3011b will be closer to the water guide surface 211 than the first end 3011a.

[0101] At least a portion of the water-guiding surface 211 extends at an angle relative to the horizontal plane and includes a water-guiding end 2111 and a water-outlet end 2112 with a height difference. The first end 3011a of the mating surface 3011 is closer to the water-outlet end 2112 (lower end) of the water-guiding surface 211. Correspondingly, the second end 3011b of the mating surface 3011 is closer to the water-guiding end 2111 (higher end) of the water-guiding surface 211.

[0102] Thus, the inclined structure of the water-guiding surface 211 and the inclined posture of the mating surface of the float part 301 complement each other, forming a triangular region between the water outlet end 2112 of the water-guiding surface 211 and the first end 3011a of the float part 301, which can collect more water. In the case of low water level, the limited water flows along the water-guiding surface 211 to its lower water outlet end 2112 under the action of gravity and collects in this triangular region. The contact area between the water and the mating surface 3011 increases, thereby giving the float part 301 greater buoyancy than the parallel design. This improves the buoyancy response sensitivity of the float part 301 at low water level, enabling it to float up promptly and reliably as the water level rises.

[0103] like Figure 6 and Figure 9 As shown, in some embodiments, the water guiding surface 211 includes a first water guiding part 2113 and a second water guiding part 2114 connected together. The first water guiding part 2113 corresponds to the float part 301. The first water guiding part 2113 is inclined relative to the horizontal plane and is higher than the drainage surface 212.

[0104] The water guiding surface 211 includes a first water guiding part 2113 and a second water guiding part 2114 that are connected to each other. The projection area of ​​the first water guiding part 2113 on the horizontal plane covers the float part 301. The first water guiding part 2113 is configured to be inclined relative to the horizontal plane, and the height of the lowest point of the first water guiding part 2113 is still higher than the height of the drainage surface 212.

[0105] The projection area of ​​the second water guide 2114 on the horizontal plane covers the trigger 303. It can be configured to be inclined relative to the horizontal plane or parallel to the horizontal plane. The overall height of the second water guide 2114 is higher than that of the first water guide 2113, thereby forming a height step between the first water guide 2113 and the second water guide 2114.

[0106] Specifically, the higher second water guide section 2114 preferentially receives the water flowing from the outlet of the drain valve 102, and then the water flows naturally from the higher second water guide section 2114 to the lower first water guide section 2113 under the action of gravity. The first water guide section 2113 accelerates the water flow and guides it to the drain surface 212 and the drain outlet 2121 through its inclined surface, thereby improving the water replenishment efficiency.

[0107] The tilt angle of the first water guiding part 2113 and the tilt posture of the mating surface 3011 of the float part 301 work together. At low water levels, water is concentrated and guided to the surface of the first water guiding part 2113, and due to the tilt angle, it gathers in the area where the float part 301 sinks the deepest (i.e. below the first end 3011a of the mating surface 3011), which increases the drainage volume of the float part 301, thereby increasing the buoyancy of the float part 301 and improving the response sensitivity of the float part 301.

[0108] like Figure 12 As shown, in some embodiments, the humidifier 1 also includes a light-emitting element 203, which is disposed on the base 20 and located outside the water tank 21.

[0109] Specifically, the light-emitting element 203 can be fixedly installed on the housing structure around the base or the water tank 21, with its light emission direction facing the water tank 10. The light emitted by the light-emitting element 203 can be used to indicate the working status of the humidifier 1, provide nighttime lighting, or create a decorative atmosphere.

[0110] The light-emitting element 203 is located outside the water tank 21, which physically isolates the light source from the water vapor environment inside the water tank 21 and improves the service life of the light-emitting element 203.

[0111] In some embodiments, the water tank 21 further includes a light-transmitting portion 214. The light-transmitting portion 214 corresponds to the light-emitting element 203 and is used to allow the light emitted by the light-emitting element 203 to pass through the water tank 21 and be visible from the outside of the humidifier 1.

[0112] The light-transmitting part 214 protrudes from the drainage surface 212, and the height of the light-transmitting part 214 is not lower than the height of the outlet of the drainage channel 101. The water level in the water tank 21 is lower than the top of the light-transmitting part 214, which can improve the stability of the light generated by the light-emitting element 203, reduce the brightness fluctuation phenomenon that may be caused by liquid surface sloshing or liquid level changes, and improve the visual effect of lighting or ambient light.

[0113] like Figure 11 As shown, in some embodiments, a mist exhaust channel 103 is formed inside the water tank 10 to exhaust the water mist generated by the atomizing plate from the humidifier 1, and the light-transmitting part 214 is located within the projection range of the mist exhaust channel 103 in the vertical direction.

[0114] The light-transmitting part 214 faces the lower area of ​​the de-fogging channel 103, allowing the light emitted by the light-emitting element 203 to directly illuminate the rising water mist in the de-fogging channel 103 from bottom to top. The concentrated light shines on the water mist particles and forms diffuse reflection on the water mist particles, which can enhance the visual atmosphere of mist.

[0115] In some embodiments, the drain outlet 2121 is located within the vertical projection range of the mist exhaust channel 103. That is, when viewed from the vertical direction, the drain outlet 2121 is contained within the area defined by the mist exhaust channel 103. This allows the water mist generated when the atomizing plate is working to be discharged into the mist exhaust channel 103 more concentratedly, reducing the diffusion loss and condensation of water mist during the transportation process and improving atomization efficiency.

[0116] like Figure 12As shown, in some embodiments, a guide post 215 is provided on the drainage surface 212, and a magnetic element 216 is sleeved on the guide post 215. The magnetic element 216 can reciprocate along the guide post 215 as the water level in the water tank 21 changes.

[0117] In some embodiments, a recess 2122 is formed on the drainage surface 212, and a guide post 215 is disposed within the recess 2122. The magnetic element 216 can be accommodated within the recess 2122 when it is in its extreme position.

[0118] The humidifier 1 also includes a Hall sensor, which is located on the base 20 and outside the water tank 21. The Hall sensor is magnetically coupled to the magnetic component 216 to detect the water level in the water tank 21.

[0119] By confining the movement trajectory of the magnetic component 216 within the guide post 215, the risk of the magnetic component 216 detaching from the guide post 215 due to water flow impact or equipment shaking is reduced, thereby improving the reliability and durability of water level detection.

[0120] like Figure 12 As shown, the recess 2122 improves the low water level detection range, allowing the magnetic component 216 to descend to a lower position during low water levels. Furthermore, the recess 2122 design increases the relative distance between the magnetic component 216 and the Hall sensor mounted on the base 20. This change in distance makes the change in magnetic field strength more noticeable, thus making it easier for the Hall sensor to detect the water shortage signal corresponding to the positional change of the magnetic component 216.

[0121] like Figure 10 As shown, in some embodiments, the seat 20 has a receiving cavity 202, and the water tank 21 is detachably disposed in the receiving cavity 202, with a preset distance between the water tank 21 and the cavity wall of the receiving cavity 202.

[0122] The air layer between the water tank 21 and the base 20 can block and attenuate the operating noise generated in the water tank 21 (such as the sound of water droplets hitting the liquid surface when the atomizing plate is working, and the sound of the water tank 10 replenishing water to the water tank 21), which helps to reduce the operating noise of the humidifier 1.

[0123] In addition, if the water tank 21 leaks unexpectedly, the humidifying water can be temporarily stored in this space, reducing the probability that the overflowing water will immediately seep out of the humidifier 1, thus improving the safety and reliability of the humidifier 1.

[0124] In some embodiments, such as Figure 13 As shown, the bottom wall of the water tank 21 is provided with reinforcing ribs 217 facing the seat 20, and at least some of the reinforcing ribs 217 are arranged around the drain outlet 2121.

[0125] The bottom of the water tank 21 is provided with reinforcing ribs 217, which enhances the overall structural rigidity of the bottom wall of the water tank 21, thereby reducing local deformation caused by changes in water level, temperature fluctuations or external pressure inside the water tank 21.

[0126] At least some reinforcing ribs 217 are provided around the drain outlet 2121, which can provide targeted support for the surrounding area of ​​the drain outlet 2121 and help maintain the stability of the shape and position of the drain outlet 2121. This aligns the drain outlet 2121 with the atomizing plate below, reducing the probability of water leakage or uneven water supply to the atomizing plate due to misalignment.

[0127] 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.
