Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and in particular to a water tank device and a humidifier. Background Technology

[0002] In related technologies, water tanks primarily rely on gravity drainage. During long-term use, water droplets easily adhere to the side walls of the water tank and are difficult to remove. These droplets can accumulate as dirt on the tank's side walls. When the water tank is used with an electrical appliance (such as a humidifier), even if the tank is detachably connected to the appliance, residual water droplets will still remain, affecting the hygiene of the appliance and the user experience. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application provides a water tank device and a humidifier capable of automatically cleaning and removing water droplets adhering to the inner wall of the water tank, reducing the probability of dirt formation on the inner wall of the water tank, and improving the hygiene of the humidifier and the user experience.

At least a portion of the outer wall of the wiping member contacts the inner wall of the second space. The drive unit is configured to drive the wiping member to slide along the inner wall of the second space and the inner wall of the first space in the height direction.

[0007] A water collection component is located at the bottom of the water tank. The water collection component has an open state that communicates with the first space and a closed state that is isolated from the first space. When the water collection component is in the open state, it can receive liquid water flowing down from the first space.

[0009] The water tank device of this application, through the coordinated arrangement of a water tank, a water removal component, and a water collection component, allows the water removal component to be periodically activated during the use of the water tank device. A drive unit drives the wiping component to slide back and forth along the inner wall of the second space at the top of the water tank, wiping away water droplets adhering to the inner wall of the second space. Simultaneously, after the liquid water in the water tank is depleted, the drive unit can also drive the wiping component to slide back and forth sequentially along the inner walls of the second space and the first space, wiping away water droplets adhering to the overall inner wall of the water tank. The water collection component can be switched to the open state to collect liquid water that has slid down from the inner wall of the water tank. This improves the hygiene of the water tank device and the humidifier equipped with it, as well as the user experience.

[0014] In some embodiments, the water shield includes a first water baffle and a second water baffle, the first water baffle being connected to the inner wall of the second space, the second water baffle being connected to the end of the first water baffle away from the inner wall of the second space, and the first water baffle and the second water baffle forming an angle.

[0015] In some embodiments, the water collection assembly includes a water collection box and a seal. The water collection box is detachably connected to the bottom outer wall of the water tank to form a water collection cavity. A drainage channel communicating with the water collection cavity is formed at the bottom of the water tank. The seal is used to block or open the drainage channel.

[0016] In some embodiments, the seal is configured as an elastic sealing ring, the drainage channel extends into the water collection cavity and abuts against the seal, and the water collection box is detachably fastened to the bottom outer wall of the water tank so that the bottom wall of the water collection box presses the seal against the drainage channel.

[0017] In some embodiments, the seal has a limiting slot, and the bottom of the drainage channel is interference-fitted into the limiting slot.

[0023] The humidifier of this application, due to the configuration of the aforementioned water tank device, also possesses the same technical effects brought by the water tank device. That is, through the coordinated arrangement of the water tank, the water removal component, and the water collection component, the water removal component can be periodically activated during the use of the humidifier. The wiping component is driven by the drive unit to slide back and forth along the inner wall of the second space at the top of the water tank, wiping away the water droplets adhering to the inner wall of the second space. At the same time, after the liquid water in the water tank is exhausted, the wiping component can also be driven by the drive unit to slide back and forth along the inner walls of the second space and the first space in sequence, wiping away the water droplets adhering to the inner wall of the entire water tank. The water collection component can be switched to the open state to collect the liquid water that has slid down from the inner wall of the water tank. In this way, the hygiene of the humidifier and the user experience are improved.

Detailed Implementation

[0035] 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.

[0036] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0037] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0041] In related technologies, water tanks primarily rely on gravity drainage. During long-term use, water droplets easily adhere to the side walls of the water tank and are difficult to remove. These droplets can accumulate as dirt on the tank's side walls. When the water tank is used with an electrical appliance (such as a humidifier), even if the tank is detachably connected to the appliance, residual water droplets will still remain, affecting the hygiene of the appliance and the user experience.

[0042] Based on this, one or more embodiments of this application provide a water tank device. Through the coordinated arrangement of a housing, a water tank, a water removal component, and a water collection component, the water removal component can be periodically activated during the use of the water tank device. The wiping component is driven by a drive unit to slide back and forth along the inner wall of the second space at the top of the water tank to wipe away water droplets adhering to the inner wall of the second space. At the same time, after the liquid water in the water tank is used up, the wiping component can be driven by the drive unit to slide back and forth along the inner wall of the second space and the inner wall of the first space in sequence to wipe away water droplets adhering to the inner wall of the entire water tank. The water collection component can be switched to the open state to collect the liquid water that has been wiped off the inner wall of the water tank. In this way, the hygiene of the water tank device and the humidifier equipped with the water tank device are improved, as well as the user experience.

[0043] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a water tank device, which includes a water tank 200, a water removal component 300, and a water collection component 400.

[0044] The water tank 200 includes a first space 210 below the liquid surface and a second space 220 above the liquid surface.

[0045] The water removal assembly 300 is disposed in the second space 220. The water removal assembly 300 includes a drive unit 310 and a wiping member 320 connected to the drive unit 310. At least a portion of the outer wall of the wiping member 320 contacts the inner wall of the second space 220. The drive unit 310 is configured to drive the wiping member 320 to slide along the inner wall of the second space 220 and the inner wall of the first space 210 in the height direction Z.

[0046] The water collection component 400 is located at the bottom of the water tank 200. The water collection component 400 has an open state that communicates with the first space 210 and a closed state that is isolated from the first space 210. When the water collection component 400 is in the open state, it can receive liquid water flowing down from the first space 210.

[0047] In addition, this application embodiment also provides a humidifier, which includes a housing 100 and the above-mentioned water tank device, the water tank device being disposed inside the housing 100.

[0048] It should be noted that, in this application, the shell 100 refers to a shell-like structure used to accommodate and protect internal components and guide airflow. The shell 100 may be, but is not limited to, a square shell, a cylindrical shell, an elliptical shell, etc.

[0049] In this application, the water tank 200 can be integrally formed with the shell 100, or it can be a separate structure detachably installed inside the shell 100. See also Figure 2 and Figure 3 In the diagram, the thick horizontal dashed line represents the liquid surface of the water tank 200. The first space 210 and the second space 220 intersect at the liquid surface of the water tank 200. Moving downwards along the height direction Z of the water tank 200, the second space 220 and the first space 210 are sequentially distributed, representing the upper and lower spaces of the water tank 200, respectively. The water tank 200 is used to contain and store liquid water. The first space 210 is below the liquid surface and can be understood as the liquid phase space, while the second space 220 is above the liquid surface and can be understood as the gas phase space.

[0050] See also in this application. Figure 1 and Figure 2 An air inlet 110 and an air outlet 120 are spaced apart on the outer wall of the housing 100. An air duct cavity 130 is formed inside the housing 100, and the air duct cavity 130 is connected to the air inlet 110 and the air outlet 120.

[0051] See Figure 2 The humidifier also includes a wet curtain assembly 500 and a water pump assembly 700. The wet curtain assembly 500 is disposed within the air duct cavity 130 and near the opening of the water tank 200. The wet curtain assembly 500 includes a wet curtain 510 and a liquid distributor 520, with the liquid distributor 520 located above the wet curtain 510. The water pump assembly 700 includes a water pump 710 and a liquid supply pipe 720. The water pump 710 is located at the bottom of the water tank 200, i.e., at the bottom of the first space 210. The water pump 710 is connected to the liquid distributor 520 through the liquid supply pipe 720 to deliver liquid water to the liquid distributor 520.

[0052] See Figure 2The humidifier also includes a fan assembly 600, which is disposed within the air duct cavity 130 and near the air outlet 120. The fan assembly 600 drives the airflow along the air inlet 110 of the housing 100 into the air duct cavity 130, where it is humidified and cooled by the wet curtain assembly 500 before flowing out from the air outlet 120 of the housing 100. The fan assembly 600 can be a combination of a fan and a motor.

[0053] When the humidifier is working, the water pump 710 draws liquid water from the first space 210 of the water tank 200 to the upper distributor 520. The distributor 520 evenly distributes the water flow to the lower wet curtain 510, fully wetting the wet curtain 510. At the same time, some of the liquid water on the wet curtain 510 drips directly into the lower water tank 200 by gravity, allowing the water tank 200 to recover some of the liquid water. Subsequently, the fan assembly 600 starts, forcing external airflow into the air duct cavity 130 from the air inlet 110. When the airflow passes through the wet curtain 510, the water on the wet curtain 510 absorbs the heat of the airflow and evaporates, thus cooling the airflow. This results in the airflow exiting from the air outlet 120 being a cool airflow with a lower temperature, achieving both humidification and cooling of the environment.

[0054] In this application, for the water removal assembly 300, the drive unit 310 can be installed at the top opening of the water tank 200, and the wiping member 320 contacts one vertical inner wall of the second space 220. Alternatively, the wiping member 320 can be annular, contacting all vertical inner walls of the second space 220. Alternatively, there can be multiple wiping members 320 and drive units 310, with multiple wiping members 320 respectively contacting corresponding inner walls of the second space 220 along the circumferential direction, and the drive unit 310 driving the corresponding wiping member 320 to slide along the corresponding inner wall of the second space 220 in the height direction Z. Alternatively, there can be multiple wiping members 320 and one drive unit 310, with multiple wiping members 320 respectively contacting corresponding inner walls of the second space 220 along the circumferential direction, and all wiping members 320 being driven by the same drive unit 310 to slide along the corresponding inner wall of the second space 220 in the height direction Z.

[0055] It is easy to understand that the first space 210 and the second space 220 are the lower and upper parts of the water tank 200, respectively, and their inner walls are directly vertically connected. The drive unit 310 can drive the wiping component 320 to slide back and forth along the inner wall of the second space 220 and the inner wall of the first space 210.

[0056] The wiping component 320 can be constructed as an absorbent sponge, such as a sponge roller or a sponge belt, and the drive unit 310 can be a cylinder, a linear motor, or the like, with no specific limitations.

[0057] In this application, the water collection component 400 can be a water receiving box with a water valve. The water receiving box is connected to the first space 210. The water valve is set at the connection between the water receiving box and the first space 210. The water collection component 400 is switched between open and closed states by the water valve.

[0058] It should be noted that during long-term use, water droplets will continuously adhere to the inner wall of the second space 220 of the water tank 200. Therefore, the drive unit 310 can be periodically activated to drive the wiping member 320 to slide back and forth along the inner wall of the second space 220 in the height direction Z. The wiping member 320 cleans the inner wall of the second space 220, reducing the amount of water droplets remaining. Some of the wiped water droplets fall into the first space 210 due to gravity, while some adhere to the wiping member 320 and are absorbed. This not only reduces the probability of dirt formation on the inner wall of the second space 220 but also helps to recover some liquid water, improving the hygiene of the water tank device and the humidifier equipped with it, as well as the user experience.

[0059] In addition, when the liquid water in the water tank 200 of the humidifier is used up, the drive unit 310 can drive the wiping member 320 to slide back and forth along the inner wall of the second space 220 and the inner wall of the first space 210 in sequence to wipe away the water droplet residue on the inner wall of the entire water tank 200.

[0060] Of course, the drive unit 310 can also be activated by a signal trigger. For example, in some embodiments of this application, the humidifier may also include a controller (not shown in the figure) and a humidity sensor (not shown in the figure). The humidity sensor is disposed in the second space 220 to detect the humidity value in the second space 220. The controller is communicatively connected to the drive unit 310 and the humidity sensor. During long-term use of the humidifier, the humidity value in the second space 220 will continuously increase, and water droplets will gradually accumulate on the inner wall of the second space 220. Based on this, when the humidity sensor detects that the humidity value in the second space 220 is greater than the humidity threshold, the controller controls the drive unit 310 to be activated according to the detection signal of the humidity sensor, so that the drive unit 310 drives the wiping member 320 to slide back and forth along the inner wall of the second space 220 in the height direction Z, thereby achieving the effect of automatically wiping and cleaning water droplets.

[0061] Additionally, it should be noted that in this application, when the water tank device or humidifier equipped with the water tank device is working normally, the water collection component 400 is in a closed state to ensure full utilization of the liquid water in the water tank 200. When the liquid water in the water tank 200 is used up and the tank is idle for a long time, the water collection component 400 can be switched to an open state. The water collection component 400 collects the liquid water that has slid down from the inner walls of the second space 220 and the first space 210 by the wiping member 320, thereby removing the residual liquid water in the water tank 200 and improving the hygiene of the water tank 200.

[0062] Based on the above description, it is easy to understand that the water tank device of this application embodiment, through the coordinated arrangement of the water tank 200, the water removal component 300, and the water collection component 400, can periodically activate the water removal component 300 during the use of the water tank device. The wiping member 320 is driven by the drive unit 310 to slide back and forth along the inner wall of the second space 220 at the top of the water tank 200 to wipe and clean the water droplets attached to the inner wall of the second space 220. At the same time, after the liquid water in the water tank 200 is used up, the wiping member 320 can be driven by the drive unit 310 to slide back and forth along the inner wall of the second space 220 and the inner wall of the first space 210 in sequence to wipe and clean the water droplets attached to the inner wall of the entire water tank 200. The water collection component 400 can be switched to the open state to receive the liquid water that has been wiped off the inner wall of the water tank 200. In this way, the hygiene of the water tank device and the humidifier equipped with the water tank device is improved, as well as the user experience.

[0063] In some embodiments of this application, see Figure 3 , Figure 4 , Figure 7 and Figure 8 The water removal assembly 300 also includes a positioning rod 330, a wiping member 320 is constructed as a cylindrical structure, the wiping member 320 is rotatably sleeved on the positioning rod 330, and the output end of the drive unit 310 is connected to the positioning rod 330.

[0064] Specifically, the positioning rod 330 includes a horizontal section 331 and a vertical section 332. The wiping element 320 is sleeved on the horizontal section 331, and the output end of the drive unit 310 is connected to the vertical section 332. The wiping element 320 is a sponge tube, which has a certain water absorption capacity and absorbs and cleans some water droplets during the wiping process.

[0065] In the above structure, the drive unit 310 drives the wiping component 320 to roll and slide along the inner wall of the second space 220 or the inner wall of the first space 210 by driving the positioning rod 330 to rise and fall. This allows multiple parts of the wiping component 320 in the circumferential direction to wipe and clean water droplets in sequence, avoiding the fixed parts of the wiping component 320 from absorbing water and wetting themselves, thus reducing the wiping efficiency of the wiping component 320.

[0066] Furthermore, by positioning, installing, and shaping the wiping component 320 using the positioning rod 330, the shape of the wiping component 320 is kept relatively regular, ensuring that the wiping component 320 maintains stable contact with the inner wall of the second space 220 or the inner wall of the first space 210 when it rolls and slides. This also ensures that the contact area between the wiping component 320 and the inner wall of the second space 220 or the inner wall of the first space 210 is relatively stable, thus guaranteeing the wiping efficiency of the wiping component 320 in cleaning water droplets.

[0067] See also some embodiments of this application. Figure 3 , Figure 4 , Figure 7 and Figure 8 The wiping member 320 is configured to remain parallel and tangent to the inner wall of the second space 220 or the inner wall of the first space 210 when sliding in the height direction Z.

[0068] For example, in one embodiment, the positioning rod 330 includes a horizontal segment 331 and a vertical segment 332 that are straight lines. The wiping member 320 is sleeved on the horizontal segment 331, and the output end of the drive unit 310 is connected to the vertical segment 332. The horizontal extension length of the wiping member 320 is close to the length or width of the inner wall of the water tank 200, so that the wiping member 320 can cover and wipe a larger area of ​​the inner wall of the water tank 200 when it slides.

[0069] For example, in one embodiment, the positioning rod 330 includes a horizontal section 331 and a vertical section 332. The horizontal section 331 is annular and extends circumferentially along the inner sidewall of the water tank 200. Correspondingly, the wiping member 320 is fitted onto the horizontal section 331 along the annular trajectory of the horizontal section 331, so that the wiping member 320 can cover and wipe the entire inner sidewall of the water tank 200 when it slides.

[0070] It should also be noted that, thanks to the rotatable mounting of the wiping component 320 on the positioning rod 330, when the drive unit 310 drives the wiping component 320 to move up and down via the positioning rod 330, the wiping component 320 rolls along the inner wall of the water tank 200, maintaining a state that is parallel and tangential to the inner wall of the water tank 200. This not only avoids the fixed part of the wiping component 320 from absorbing water and becoming wet, thus reducing the wiping efficiency of the wiping component 320, but also allows the wiping component 320 to cover and wipe a larger area of ​​the inner wall of the water tank 200 when it slides, thereby improving the wiping and cleaning efficiency.

[0071] In some embodiments of this application, see Figure 3 , Figure 4 , Figure 6 and Figure 7The water removal assembly 300 also includes a water shield 340, which is connected to the inner wall of the second space 220. The water shield 340 and the inner wall of the second space 220 form a water-blocking groove 350 with an opening facing the first space 210. The water-blocking groove 350 covers the wiping member 320.

[0072] Specifically, there are two water removal components 300, which are respectively arranged on the top of the two opposite inner sidewalls of the second space 220 along the length or width direction. The water shield 340 can be connected to the top of the inner sidewall of the second space 220 by means of threads, welding, snaps, etc., and kept in a fixed state.

[0073] The water shield 340 is a right-angled plate that forms an inverted U-shaped water-blocking groove 350 with the inner wall of the second space 220. The top of the water shield 340 is provided with a clearance hole for the output end of the drive unit 310 or the vertical section 332 of the positioning rod 330 to pass through, ensuring that the output end of the drive unit 310 and the wiping member 320 form a stable direct or indirect connection.

[0074] On the projection plane perpendicular to the height direction Z, the orthographic projection of the wiping member 320 falls within the orthographic projection of the water-retaining groove 350; on the projection plane parallel to the height direction Z, the orthographic projection of the wiping member 320 falls within the orthographic projection of the water-retaining groove 350. In this way, the water-retaining groove 350 can always maintain a state where it completely covers the wiping member 320.

[0075] Understandably, when the humidifier is working, some of the liquid water on the wet curtain assembly 500 will fall into the second space 220 by gravity and eventually flow into the liquid water in the first space 210.

[0076] Based on this, the above structure, by forming a water-blocking groove 350 with the inner wall of the second space 220 and the water shield 340 facing the first space 210, allows the water-blocking groove 350 to always cover the wiping member 320 when the wiping member 320 is performing wiping operations, preventing liquid water falling from the wet curtain assembly 500 from contacting the wiping member 320 and reducing the wiping efficiency of the wiping member 320.

[0077] Further, see Figure 3 and Figure 4 The water shield 340 includes a first water baffle 341 and a second water baffle 342. The first water baffle 341 is connected to the inner wall of the second space 220, and the second water baffle 342 is connected to the end of the first water baffle 341 away from the inner wall of the second space 220, and an angle is formed between the first water baffle 341 and the second water baffle 342.

[0078] It should be noted that, taking the maximum span direction of the horizontal cross-section of the water tank 200 as the reference point for the length direction of the water tank 200, the first baffle plate 341 is parallel to the horizontal cross-section of the water tank 200. The length of the first baffle plate 341 is much smaller than the overall length of the second space 220, reducing the impact of the first baffle plate 341 on the liquid water during the process of some liquid water falling into the first space 210 due to gravity on the wet curtain assembly 500. The first baffle plate 341 and the second baffle plate 342 can be set vertically, with the second baffle plate 342 parallel to the height direction of the water tank 200. In this way, it can directly stop the liquid water dripping from the wet curtain assembly 500.

[0079] The drive unit 310 can be fixed to the side surface of the first baffle plate 341 facing away from the first space 210, and the first baffle plate 341 is provided with a clearance hole for the output end of the drive unit 310 or the vertical section 332 of the positioning rod 330 to pass through vertically, so as to ensure that the output end of the drive unit 310 and the wiping member 320 form a stable direct or indirect connection, and avoid structural interference caused by the lifting and sliding of the first baffle plate 341 on the wiping member 320.

[0080] It is understandable that the wiping component 320 is located below the first water baffle 341, and the outer side of the wiping component 320 is surrounded by the water baffle groove 350 formed by the inner side wall of the second space 220, the first water baffle 341 and the second water baffle 342, to prevent liquid water falling from the wet curtain assembly 500 from contacting the wiping component 320 and reducing the wiping efficiency of the wiping component 320.

[0081] In some embodiments of this application, see Figure 2 , Figure 3 and Figure 5 The water collection assembly 400 includes a water collection box 420 and a seal 430. The water collection box 420 is detachably connected to the bottom outer wall of the water tank 200 to form a water collection cavity 440. The bottom of the water tank 200 has a drainage channel 230 that communicates with the water collection cavity 440. The seal 430 is used to block or open the drainage channel 230.

[0082] Specifically, the water collection assembly 400 may also include a first cover 410, which is fixed to the bottom outer wall of the water tank 200 by welding, gluing or other means. The first cover 410 has a downward-facing groove structure, and the water collection box 420 has an upward-facing groove structure. The first cover 410 and the water collection box 420 are joined together in the vertical direction to form a water collection cavity 440. The first cover 410 and the water collection box 420 can be connected by bolts, interference fits or other means to form a stable connection.

[0083] The sealing element 430 can be an electronic valve installed in the drainage channel 230. The electronic valve is communicatively connected to the humidifier's controller. The controller controls the electronic valve to open or close based on whether the liquid water in the water tank 200 is at a preset level. For example, when the liquid water in the water tank 200 is at the preset level, the controller controls the drive unit 310 to start, driving the wiping element 320 to wipe away water droplets adhering to the inner wall of the second space 220. At the same time, the controller controls the electronic valve to open, so that the water collection chamber 440 can simultaneously receive the liquid water that has been wiped off through the drainage channel 230 while the wiping element 320 is performing the wiping operation.

[0084] With the above structure, when the sealing element 430 blocks the drainage channel 230, it prevents the liquid water in the water tank 200 from flowing into the water collection chamber 440, thus avoiding waste of liquid water and ensuring full utilization of liquid water. When the liquid water in the water tank 200 is used up, the sealing element 430 can open the drainage channel 230 to collect the unclean water droplets that are attached to the inner side wall of the water tank 200 and wiped off by the wiping element 320. It can also remove the water collection box 420 from the first cover 410 to directly pour out the unclean liquid water collected in the water collection box 420, thus achieving efficient cleaning of residual liquid water.

[0085] Further, see Figure 2 , Figure 3 and Figure 5 The seal 430 is constructed as an elastic sealing ring, the drainage channel 230 extends into the water collection cavity 440 and abuts against the seal 430, and the water collection box 420 is detachably fastened to the bottom outer wall of the water tank 200 so that the bottom wall of the water collection box 420 presses the seal 430 against the drainage channel 230.

[0086] See Figure 5 The water collection assembly 400 also includes a first cover 410, which is fixed to the bottom outer wall of the water tank 200 by welding, gluing or other means. That is, the water collection box 420 is indirectly connected to the bottom outer wall of the water tank 200 through the first cover 410. The water collection box 420 and the first cover 410 are threadedly connected to form a sealed water collection cavity 440. By extending the drainage channel 230 into the water collection cavity 440 and abutting against the sealing element 430, the sealing element 430 can be compressed and deformed under the force of the threaded connection between the water collection box 420 and the first cover 410, filling the gap between the drainage channel 230 and the bottom wall of the water collection box 420, so that the drainage channel 230 is in a blocked state.

[0087] When it is necessary to open the drainage channel 230, simply screw on the water collection box 420 to reduce the threaded connection force between the water collection box 420 and the first cover 410, release the seal 430, and open or even widen the gap between the drainage channel 230 and the bottom wall of the water collection box 420, so that the residual liquid water in the water tank 200 can flow smoothly into the water collection chamber 440 through the drainage channel 230. The water collection box 420 can be disassembled by directly unscrewing the threads from the first cover 410, and the unclean liquid water in the water collection box 420 can be poured out, thus achieving convenient cleaning of residual liquid water.

[0088] The above structure eliminates the need for electronic or mechanical valves. Instead, the threaded connection force between the water collection box 420 and the first cover 410 can be adjusted by screwing the water collection box 420, thereby indirectly adjusting the elastic deformation of the seal 430. This mechanically opens or closes the drainage channel 230, simplifying the structure, reducing structural costs, and allowing users to manually and quickly empty unclean liquid water from the water collection box 420 according to their needs.

[0089] Further, see Figure 5 The sealing element 430 has a limiting slot 431, and the bottom of the drainage channel 230 is interference-fitted into the limiting slot 431.

[0090] Specifically, the limiting slot 431 is an annular groove, and the drainage channel 230 is an annular channel.

[0091] By inserting the bottom of the drainage channel 230 into the limiting slot 431 with an interference fit, the seal 430 can be kept fixed at the bottom of the drainage channel 230. This ensures that the seal 430 will not fall off during the process of screwing the water collection box 420 to adjust the threaded connection force between the water collection box 420 and the first cover 410, but will only undergo elastic deformation. This improves the efficiency of disassembling and assembling the water collection box 420, thereby further improving the cleaning efficiency of residual liquid water in the water tank 200.

[0092] Additionally, in some embodiments of this application, see [link to relevant documentation]. Figure 2 and Figure 3 The bottom inner wall of the water tank 200 is inclined from the edge of the water tank 200 to the drainage channel 230.

[0093] Specifically, the drainage channel 230 is located at the center of the water tank 200, and the bottom inner wall of the water tank 200 is set as an inclined surface or arc-shaped surface that slopes towards the center of the water tank 200.

[0094] In this way, guided by the inner wall of the bottom of the water tank 200, the water droplets on the inner wall of the water tank 200 slide down to the drainage channel 230 more quickly and smoothly, and quickly enter the water collection box 420, so as to remove and clean the residual liquid water in the water tank 200 more efficiently, and further improve the hygiene of the humidifier and the user experience.

[0095] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
