Description

Technical Field

[0001] The present application relates to the technical field of air humidification electrical equipment, and in particular to a humidification device. Background Art

[0002] A humidifier is a device used to adjust the humidity of the air. According to different working principles, humidifiers can be divided into three categories: electric heating humidifiers, ultrasonic humidifiers and evaporative humidifiers. Evaporative humidifiers are becoming more and more popular among consumers because of their low water quality requirements and energy saving.

[0003] An evaporative humidifier usually includes a main unit and a water tank. The main unit includes a housing, a fan and a filter element. The water tank is used to store water and provide it to the filter element. The filter element is used to absorb moisture and then guide the airflow through the filter element and blow it out through the fan, so that the airflow carries water vapor and is blown out of the humidifier, thereby achieving the purpose of humidifying the air. However, since the water tank in the prior art is arranged below the main unit, the water in the water tank needs to be pumped into the main unit by a water pump and then sprayed onto the filter element through a spray pipe. Since the water pump will generate noise when working, and the water pump will also increase the cost of the humidifier, the cost of the humidifier is high and the user experience is poor. Utility Model Content

[0006] The wet curtain assembly includes a wet curtain unit and a water receiving tray, the wet curtain unit includes a wet curtain, the water receiving tray is connected to the housing, the water receiving tray has a water storage tank, the wet curtain is connected to the water storage tank, the water tank assembly includes a water tank and a sealing unit, the bottom of the water tank has a water outlet, and the water outlet is connected to the wet curtain;

[0007] The liquid level control assembly includes a transmission unit and a floating member. The transmission unit includes a connecting member, which is rotatably arranged on the shell. The sealing unit and the floating member are respectively located at both ends of the connecting member. The floating member is floated on the water storage tank to drive the sealing unit to open or close the drain outlet through the connecting member.

[0008] The humidifying device provided in the embodiment of the present application is provided with a water outlet for connecting the water tank and the wet curtain, a sealing unit for controlling the on-off state of the water outlet, a wet curtain for absorbing liquid and then evaporating, a fan assembly for driving air flow to accelerate the evaporation of liquid on the wet curtain, a water storage tank for temporarily storing excess liquid for use by the wet curtain, a floating member for sensing the liquid level of the water storage tank, and then controlling the on-off state of the water outlet according to the liquid level of the water storage tank, a connecting member for transmitting the force of the floating member to the sealing unit, and then driving the sealing unit to open or close the water outlet, and the wet curtain is provided below the water outlet so that the liquid flows directly to the wet curtain under the action of gravity after the water outlet is opened, so as to eliminate the water pump, thereby reducing the cost of the humidifying device and the noise generated by the water pump, and at the same time making the wet curtain fully absorb the liquid to improve the humidification effect of the humidifying device. Therefore, the humidifying device provided in the embodiment of the present application has low cost, low noise, and good humidification effect.

[0009] In a possible implementation, the wet curtain unit further includes an upper cover connected to one end of the wet curtain facing the water tank, and the side of the upper cover facing the water tank has a downwardly inclined guide surface, and the lower water outlet is connected to the guide surface.

[0010] In this way, when the downspout is opened, the liquid in the water tank flows out from the downspout under the action of its own gravity, and then falls onto the guide surface. Since the guide surface is tilted downward, the liquid can be guided to the upper end of the wet curtain, and then the liquid flows through various parts of the wet curtain from top to bottom, so that the wet curtain can fully absorb the liquid.

[0011] In a possible implementation, the upper cover also has a guide hole, which runs through two opposite sides of the upper cover, and the guide hole connects the guide surface and the wet curtain.

[0012] In this way, when the liquid flows downward along the guide surface to the guide hole, it can enter the upper end of the wet curtain through the guide hole, and then continue to flow to the lower end of the wet curtain under the action of gravity, so that the wet curtain is fully wetted.

[0013] In a possible implementation, a plurality of guide holes are arranged at intervals along the circumference of the wet curtain.

[0014] In this way, the liquid can be uniformly guided to various locations around the wet curtain through the guide surface and the guide holes.

[0015] In a possible implementation, the wet curtain unit further includes a lower cover member, the upper cover member and the lower cover member are connected to opposite ends of the wet curtain, and the lower cover member is connected to the water storage tank.

[0016] In this way, the wet curtain unit can be connected to the water storage tank through the lower cover, and then the wet curtain unit can be connected to the water receiving tray, so that the wet curtain assembly can be installed together to the housing through the water receiving tray.

[0017] In one possible implementation, the humidification host also includes a support seat, the liquid level control component also includes a liquid level detection unit, the support seat is connected to the shell, the support seat is located between the water receiving tray and the fan assembly, the liquid level detection unit includes a float and a detection sensor, the float is floatingly arranged between the lower cover and the water storage tank, the detection sensor is connected to the support seat, and the detection sensor and the float are arranged correspondingly.

[0018] In this way, the float is restricted by the water tank and the lower cover so that the float can float up and down but will not leave the water tank. At the same time, a mounting seat is provided in the shell for installing a detection sensor. The detection sensor can detect the liquid level of the water tank by detecting the relative position of the float. When the detection sensor detects that the liquid level of the water tank is low, the detection sensor can control the fan assembly to stop.

[0019] In a possible implementation, the sealing unit includes a sealing member and a first movable member that are connected to each other, the first movable member is movably disposed at the water outlet, and the sealing member and the connecting member are located at two ends of the first movable member.

[0020] In this way, when the first moving member moves along the extension direction of the drain outlet driven by the connecting member, it can drive the sealing member to move relative to the drain outlet, thereby causing the sealing member to open the drain outlet or close the drain outlet.

[0021] In a possible implementation, the sealing unit further includes a first elastic member, the first elastic member is sleeved on the first movable member, and two ends of the first elastic member in the elastic force direction are connected to the first movable member and the bottom wall of the water tank.

[0022] In this way, when the connecting member is out of contact with the first movable member, the elastic force provided by the first elastic member can make the sealing member reliably abut against the bottom wall of the water tank, thereby preventing liquid leakage, thereby improving the sealing performance of the sealing unit.

[0023] In one possible implementation, the wet curtain unit has a floating chamber, a floating member is arranged in the floating chamber, the floating chamber has a first opening and a second opening, the first end of the floating member passes through the first opening to contact the connecting member, and the second opening is connected to the water tank so that the second end of the floating member is floated and arranged in the water tank.

[0024] In this way, the floating member can be confined in the floating cavity to prevent the floating member from detaching from the wet curtain unit. At the same time, the two ends of the floating member are respectively in contact with the liquid in the water tank and the connecting member, so that the liquid in the water tank provides buoyancy for the floating member, thereby making the floating member float up and down, thereby making the floating member drive the connecting member to rotate.

[0025] In a possible implementation, the transmission unit also includes a second movable member and a second elastic member, the shell has an avoidance hole, the second movable member is rotatably connected to an end of the connecting member facing away from the drain outlet, the second movable member is movably arranged in the avoidance hole, the second elastic member is sleeved on the second movable member, and the two ends of the second elastic member in the elastic force direction are connected to the second movable member and the shell.

[0026] In this way, the floating part contacts the second movable part, and the floating part can generate a force on the end of the connecting part away from the drain outlet. When the liquid level in the water tank is low, the combined force of the elastic force of the second elastic part and the buoyancy of the liquid on the floating part prompts the connecting part to move upward toward one end of the drain outlet, and then lifts up the first movable part, so that the sealing part opens the drain outlet. When the liquid level in the water tank is high, the combined force of the buoyancy of the liquid on the floating part and the elastic force of the second elastic part prompts the connecting part to move downward toward one end of the drain outlet, and then the connecting part is out of contact with the first movable part, and the sealing part closes the drain outlet under the elastic force of the first elastic part.

[0027] In one possible implementation, the connecting member includes a lifting portion, a first rotating connecting portion and a second rotating connecting portion that are connected to each other, the first rotating connecting portion is located between the lifting portion and the second rotating connecting portion, the first rotating connecting portion is rotatably connected to the shell, the second movable member is rotatably connected to the second rotating connecting portion, and the lifting portion is constructed to abut against the sealing unit.

[0028] In this way, the connecting member can be rotated on the shell through the first rotating connection part, so that the connecting member acts as a lever. When the connecting member rotates, the end of the connecting member facing the water outlet can lift the first movable member through the lifting part, thereby driving the sealing member to open the water outlet, and the end of the connecting member away from the water outlet can be rotatably connected to the second movable member through the second rotating connection part, so that when the connecting member rotates, the second movable member can move back and forth relative to the avoidance hole.

[0029] In a possible implementation, the transmission unit further includes a rotatable connection seat, the rotatable connection seat is connected to the housing, and the connecting member is rotatably connected to the rotatable connection seat.

[0030] In this way, the first rotating connection part can be rotatably connected to the rotating connection seat, and the rotating connection seat is installed on the shell, so that the connecting member is rotatably set on the shell, so that the connecting member can rotate under the combined action of the buoyancy of the floating member and the elastic force of the second elastic member.

[0031] In a possible implementation, the liquid level control assembly further includes a mounting seat, the mounting seat is located between the water tank and the shell, the mounting seat is connected to the shell, and the rotatable connecting seat is rotatably connected to the mounting seat.

[0032] In this way, the connecting member can be rotatably connected to the rotating connecting seat through the first rotating connecting portion, the rotating connecting seat is connected to the mounting seat, and the mounting seat is connected to the shell, thereby facilitating the assembly of the liquid level control component.

[0033] In a possible implementation, the mounting seat has a first communicating hole, the shell has a second communicating hole, and the water outlet, the first communicating hole and the second communicating hole are sequentially connected between the water tank and the wet curtain unit.

[0034] In this way, by setting the first connecting hole on the mounting seat and the second connecting hole on the shell, the water outlet, the first connecting hole and the second connecting hole are connected in sequence, so that the liquid in the water tank can flow through the water outlet, the first connecting hole and the second connecting hole in sequence and reach the top of the wet curtain unit.

[0035] In a possible implementation, the shell has a mist outlet at one end facing the water tank, and has an air inlet at the bottom of the shell facing away from the water tank.

[0036] In this way, when the fan assembly is running, it drives the external air into the shell from the bottom of the shell, then flows upward through the wet curtain, and then evaporates the liquid on the wet curtain to form wet mist, and finally blows out through the mist outlet. This air flow method is more in line with the positional relationship between the wet curtain assembly and the fan assembly.

[0037] In a possible implementation, the water receiving tray has a vent located on the inner side of the water storage tank, a plurality of vents are arranged at intervals along the circumference of the water storage tank, and the vents are connected to the wet curtain unit and the fan assembly.

[0038] In this way, after the fan assembly sucks in the outside air, the air continues to flow upward to the water collection tray, and then enters the inside of the wet curtain through the vents of the water collection tray. After passing through the wet curtain, the air enters the outside of the wet curtain, thereby accelerating the evaporation of the liquid on the wet curtain, thereby forming a wet mist outflow.

[0039] In a possible implementation, the water tank includes a tank body and a tank cover, the tank body has a water inlet at one end facing away from the humidification host, and the tank cover is detachably connected to the water inlet.

[0040] In this way, when the liquid in the water tank is insufficient, the tank cover can be directly opened to add water into the tank. It is convenient to add water to the water tank. After adding water, the tank cover can be closed to prevent foreign matter from entering the water tank.

DETAILED DESCRIPTION

[0055] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions.

The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0056] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0057] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are orientations or positional relationships based on the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0058] The terms "first", "second", "third" (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0059] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or display comprising a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or display.

[0060] An evaporative humidifier usually includes a main unit and a water tank. The main unit includes a housing, a fan and a filter element. The water tank is used to store water and provide it to the filter element. The filter element is used to absorb moisture and then guide the airflow through the filter element and blow it out through the fan, so that the airflow carries water vapor and is blown out of the humidifier, thereby achieving the purpose of humidifying the air. However, since the water tank in the prior art is arranged below the main unit, the water in the water tank needs to be pumped into the main unit by a water pump and then sprayed onto the filter element through a spray pipe. Since the water pump will generate noise when working, and the water pump will also increase the cost of the humidifier, the cost of the humidifier is high and the user experience is poor.

[0061] In view of this, in the humidifying device provided in the embodiment of the present application, the water tank is arranged above the wet curtain unit. When the liquid in the wet curtain assembly is insufficient, the floating member floating on the water storage tank can drive the sealing unit to open the drain through the connecting member. Thereafter, the liquid in the water tank can flow directly to the wet curtain unit under the action of gravity, and the excess liquid can be stored in the water storage tank to continue to be used by the wet curtain unit. In this way, the water pump in the prior art can be eliminated, thereby reducing the cost and noise of the humidifying device.

[0062] The specific implementation of the humidification device provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0063] Reference Figures 1 to 7As shown, the present application provides a humidifying device, including a water tank assembly 100 and a humidifying host 200, the humidifying host 200 includes a shell 210, a wet curtain assembly 220, a fan assembly 230 and a liquid level control assembly 240, the water tank assembly 100 is connected to the top of the shell 210, the wet curtain assembly 220 and the fan assembly 230 are both arranged in the shell 210, the wet curtain assembly 220 is located between the water tank assembly 100 and the fan assembly 230, and the fan assembly 230 includes a driving motor 231.

[0064] The wet curtain assembly 220 includes a wet curtain unit 221 and a water receiving tray 222. The water receiving tray 222 is connected to the shell 210. The water receiving tray 222 has a water storage tank 2221. The wet curtain unit 221 is connected to the water storage tank 2221. The water tank assembly 100 includes a water tank 110 and a sealing unit 120. The bottom of the water tank 110 has a water outlet 111, and the water outlet 111 is connected to the wet curtain unit 221.

[0065] The liquid level control assembly 240 includes a transmission unit 241 and a floating member 242. The transmission unit 241 includes a connecting member 2411, which is rotatably connected to the shell 210. The sealing unit 120 and the floating member 242 are respectively located at two ends of the connecting member 2411. The floating member 242 is floated in the water tank 2221 to drive the sealing unit 120 to open or close the drain port 111 through the connecting member 2411.

[0066] In the present application, the water tank assembly 100 may include a water tank 110 and a sealing unit 120. A water outlet 111 is provided at the bottom of the water tank 110. The water tank 110 is used to store liquid. The water outlet 111 is used to connect the interior of the water tank 110 and the humidification host 200, so that the liquid in the water tank 110 can flow into the humidification host 200 through the water outlet 111. The sealing unit 120 is used to control the on-off state of the water outlet 111 to seal the water outlet 111 when the liquid in the humidification host 200 is sufficient, or to open the water outlet 111 when the liquid in the humidification host 200 is insufficient, so as to connect the water tank 110 and the humidification host 200.

[0067] The humidification host 200 may include a shell 210, a wet curtain assembly 220, a fan assembly 230 and a liquid level control assembly 240. The shell 210 is used to carry the wet curtain assembly 220, the fan assembly 230 and the liquid level control assembly 240. The wet curtain assembly 220 is used to absorb liquid and evaporate it, and to store excess liquid. The fan assembly 230 is used to drive air flow to form wet mist and blow it out. The liquid level control assembly 240 is used to control the liquid in the water tank 110 to flow to the wet curtain assembly 220, so that the amount of liquid required by the wet curtain assembly 220 is kept within a preset range.

[0068] It is worth noting that since the water tank 110, the wet curtain assembly 220 and the fan assembly 230 are arranged in sequence from top to bottom, the water tank 110 and the wet curtain assembly 220 are directly adjacent to each other in space. After the liquid level control assembly 240 controls the sealing unit 120 to open the drain port 111, the liquid in the water tank 110 can flow directly to the wet curtain assembly 220 under the action of gravity without the need to use a driving pump to provide driving force, thereby reducing the cost and noise of the humidification device and improving the user experience.

[0069] If the fan assembly 230 is arranged between the water tank 110 and the wet curtain assembly 220, the liquid in the water tank 110 needs to be sprayed to the wet curtain assembly 220 through a water pump and a spray structure, or the humidification host 200 needs to be provided with a more complex water guide structure to guide the liquid in the water tank 110 to the wet curtain assembly 220, thereby making the structure of the humidification device more complex and increasing the cost of the humidification device. Therefore, the wet curtain assembly 220 is arranged between the water tank 110 and the fan assembly 230, so that the liquid in the water tank 110 can flow directly to the wet curtain assembly 220 under the action of gravity, so as to avoid adding a water pump, a spray structure or a water guide structure.

[0070] The wet curtain assembly 220 may include a wet curtain unit 221 and a water receiving tray 222. The wet curtain unit 221 may include a wet curtain 2211. The water receiving tray 222 is located below the wet curtain 2211. The water tank 110 is located above the wet curtain 2211. The water receiving tray 222 has a water storage tank 2221. The wet curtain 2211 is used to absorb liquid and evaporate. When the liquid in the water tank 110 flows downward to the wet curtain 2211, the liquid flows from the top of the wet curtain 2211 to the bottom of the wet curtain 2211. This allows all parts of the wet curtain 2211 to fully absorb the liquid. Since the absorption capacity of the wet curtain 2211 is limited, the wet curtain 2211 will absorb a portion of the liquid, and the excess liquid can be temporarily stored in the water tank 2221. Since the wet curtain 2211 is connected to the water tank 2221, after a portion of the liquid in the wet curtain 2211 is evaporated, the wet curtain 2211 can continue to absorb liquid from the water tank 2221, and then continuously generate wet mist under the action of the fan assembly 230.

[0071] When the liquid in the water tank 2221 is insufficient, the liquid level control component 240 is required to control the sealing unit 120 to open the drain 111 to replenish water for the wet curtain 2211. Specifically, the liquid level control component 240 may include a transmission unit 241 and a floating member 242. The transmission unit 241 may include a connecting member 2411. The connecting member 2411 can be rotatably arranged relative to the shell 210. The sealing unit 120 and the floating member 242 can be arranged at opposite ends of the connecting member 2411, so that when the liquid amount in the water tank 2221 is insufficient, the floating member 242 can drive the connecting member 2411 to rotate, and then the connecting member 2411 drives the sealing unit 120 to open the drain 111, or, when the liquid amount in the water tank 2221 is sufficient, the floating member 242 can drive the connecting member 2411 to rotate, and then the connecting member 2411 drives the sealing unit 120 to close the drain 111. In this way, the water tank 110 can replenish the wet curtain 2211 with water in time according to the liquid level in the water storage tank 2221, thereby preventing the wet curtain 2211 from being dry-blown, thereby improving the humidification effect of the humidification device.

[0073] The humidifying device provided in the embodiment of the present application includes a water tank assembly 100 and a humidifying host 200, the humidifying host 200 includes a shell 210, a wet curtain assembly 220, a fan assembly 230 and a liquid level control assembly 240, the water tank assembly 100 includes a water tank 110 and a sealing unit 120, the water tank 110 includes a water outlet 111, the wet curtain assembly 220 includes a wet curtain unit 221 and a water receiving tray 222, the wet curtain unit 221 includes a wet curtain 2211, the water receiving tray 222 includes a water storage tank 2221, the liquid level control assembly 240 includes a transmission unit 241 and a floating member 242, and the transmission unit 241 includes a connecting member 2411. The water tank 110 is provided for storing liquid, the water outlet 111 is provided for connecting the water tank 110 and the wet curtain 2211, the sealing unit 120 is provided for controlling the on-off state of the water outlet 111, the wet curtain 2211 is provided for absorbing liquid and then evaporating, the fan assembly 230 is provided for driving air flow to accelerate the evaporation of liquid on the wet curtain 2211, the water storage tank 2221 is provided for temporarily storing excess liquid for use by the wet curtain 2211, and the floating member 242 is provided for sensing the liquid level of the water storage tank 2221, and then the liquid level of the water storage tank 2221 is increased according to the liquid level of the water storage tank 2221. The on-off state of the water outlet 111 is controlled by the liquid level of 2221, and the connecting member 2411 is provided to transmit the force of the floating member 242 to the sealing unit 120, thereby driving the sealing unit 120 to open or close the water outlet 111. The wet curtain 2211 is provided below the water outlet 111, so that after the water outlet 111 is opened, the liquid flows directly to the wet curtain 2211 under the action of gravity, thereby eliminating the water pump, thereby reducing the cost of the humidification device and the noise generated by the water pump, and at the same time allowing the wet curtain 2211 to fully absorb the liquid to improve the humidification effect of the humidification device. Therefore, the humidification device provided in the embodiment of the present application has low cost, low noise, and good humidification effect.

[0074] Reference Figure 4 , Figure 5 and Figure 7 As shown, in a possible implementation, the wet curtain unit 221 may further include an upper cover 2212, which is connected to one end of the wet curtain 2211 facing the water tank 110, and the side of the upper cover 2212 facing the water tank 110 has a downwardly inclined guide surface 2212a, and the water outlet 111 is connected to the guide surface 2212a.

[0075] With such arrangement, after the drain port 111 is opened, the liquid in the water tank 110 flows out from the drain port 111 under the action of its own gravity, and then falls onto the guide surface 2212a. Since the guide surface 2212a is arranged to be inclined downward, the liquid can be guided to the upper end of the wet curtain 2211, and then the liquid flows through various parts of the wet curtain 2211 from top to bottom, so that the wet curtain 2211 can fully absorb the liquid, and then the excess liquid can be temporarily stored in the water storage tank 2221.

[0076] Reference Figure 4 , Figure 5 and Figure 7 As shown, in a possible implementation, the upper cover 2212 further has a guide hole 2212 b , which passes through two opposite sides of the upper cover 2212 , and the guide hole 2212 b communicates with the guide surface 2212 a and the wet curtain 2211 .

[0077] It can be understood that since the guide hole 2212b connects the upper side of the upper cover 2212 and the lower side of the upper cover 2212, that is, the side of the upper cover 2212 facing the water tank 110 and the side of the upper cover 2212 facing the wet curtain 2211, when the liquid flows downward along the guide surface 2212a to the guide hole 2212b, it can enter the upper end of the wet curtain 2211 through the guide hole 2212b, and then continue to flow to the lower end of the wet curtain 2211 under the action of gravity, so that the wet curtain 2211 is fully wetted.

[0078] In some embodiments, a plurality of guide holes 2212b are arranged at intervals along the circumference of the wet curtain 2211. That is, the wet curtain 2211 can be arranged in an annular shape, and a plurality of guide holes 2212b are arranged at intervals along the circumference of the wet curtain 2211, so that the liquid can be uniformly guided to various parts of the circumference of the wet curtain 2211 through the guide surface 2212a and the guide holes 2212b.

[0079] Reference Figures 4 to 6 As shown, in a possible implementation, the wet curtain unit 221 further includes a lower cover 2213 , the upper cover 2212 and the lower cover 2213 are connected to opposite ends of the wet curtain 2211 , and the lower cover 2213 is connected to the water storage tank 2221 .

[0080] It should be noted that since the wet curtain 2211 is inconvenient to be directly connected to other structures, the upper cover 2212 and the lower cover 2213 are connected at the opposite ends of the wet curtain 2211, so that the wet curtain unit 221 can be guided by the upper cover 2212, and at the same time, the wet curtain unit 221 is connected to the water storage tank 2221 through the lower cover 2213, and then the wet curtain unit 221 is connected to the water receiving tray 222, so that the wet curtain assembly 220 is installed together with the shell 210 through the water receiving tray 222.

[0081] Reference Figure 5 , Figure 6 and Figure 7As shown, in some embodiments, the humidification host 200 also includes a support seat 250, the liquid level control component 240 also includes a liquid level detection unit 243, the support seat 250 is connected to the shell 210, the support seat 250 is located between the water receiving tray 222 and the fan assembly 230, the liquid level detection unit 243 includes a float 2431 and a detection sensor 2432, the float 2431 is floatingly arranged between the lower cover 2213 and the water storage tank 2221, the detection sensor 2432 is connected to the support seat 250, and the detection sensor 2432 is arranged corresponding to the float 2431.

[0082] It can be understood that since the lower cover 2213 is connected to the water tank 2221, excess liquid that is not absorbed by the wet curtain 2211 can enter the water tank 2221. When the liquid in the water tank 2221 reaches a preset liquid level, the sealing unit 120 can be controlled by the liquid level control component 240 to close the drain port 111. However, when the liquid in the water tank 2221 is seriously insufficient, the humidifier host 200 is in a state of water shortage as a whole. If the fan component 230 continues to operate at this time, the humidifier host 200 cannot form wet mist, but will consume unnecessary energy. At the same time, the continued idling of the fan component 230 may cause safety problems.

[0083] Therefore, in the above-mentioned setting method, the float 2431 is jointly restricted by the water tank 2221 and the lower cover 2213, so that the float 2431 can float up and down, but will not separate from the water tank 2221. At the same time, a mounting seat 244 is set in the shell 210 for installing the detection sensor 2432. The detection sensor 2432 can detect the liquid level of the water tank 2221 by detecting the relative position of the float 2431. When the detection sensor 2432 detects that the liquid level of the water tank 2221 is low, the detection sensor 2432 can control the fan assembly 230 to stop.

[0084] For example, the detection sensor 2432 may be a Hall switch, and the float 2431 may be a magnetic float 2431. When there is no water in the water tank 2221, the magnetic float 2431 is close to the Hall switch, thereby disconnecting the internal circuit of the Hall switch, thereby stopping the fan assembly 230.

[0085] Reference Figure 2 and Figure 8 As shown, in a specific implementation, the sealing unit 120 includes a sealing member 121 and a first movable member 122 connected to each other. The first movable member 122 is movably disposed at the drain port 111 . The sealing member 121 and the connecting member 2411 are located at both ends of the first movable member 122 .

[0086] Thus, when the first moving member 122 moves along the extension direction of the drain port 111 driven by the connecting member 2411 , it can drive the sealing member 121 to move relative to the drain port 111 , thereby causing the sealing member 121 to open or close the drain port 111 .

[0087] Reference Figure 2 and Figure 8 As shown, in some embodiments, the sealing unit 120 also includes a first elastic member 123, which is sleeved on the first movable member 122, and the two ends of the first elastic member 123 in the elastic direction are connected to the first movable member 122 and the bottom wall of the water tank 110.

[0088] When the connecting member 2411 is out of contact with the first movable member 122, in order to improve the sealing between the sealing member 121 and the drain outlet 111, a first elastic member 123 can be arranged between the first movable member 122 and the water tank 110, and the elastic force of the first elastic member 123 can be directed from the first movable member 122 to the bottom wall of the water tank 110. In this way, the elastic force provided by the first elastic member 123 can enable the sealing member 121 to reliably abut against the bottom wall of the water tank 110, thereby preventing liquid leakage.

[0089] Reference Figure 4 and Figure 7 As shown, in a possible implementation, the wet curtain unit 221 has a floating chamber 2214, and the floating member 242 is arranged in the floating chamber 2214. The floating chamber 2214 has a first opening and a second opening. The first end of the floating member 242 contacts the connecting member 2411 through the first opening, and the second opening is connected to the water tank 2221, so that the second end of the floating member 242 is floated and arranged in the water tank 2221.

[0090] In this way, the floating member 242 can be restricted in the floating chamber 2214 to prevent the floating member 242 from detaching from the wet curtain unit 221. At the same time, the two ends of the floating member 242 are respectively in contact with the liquid in the water tank 2221 and the connecting member 2411, so that the liquid in the water tank 2221 provides buoyancy for the floating member 242, thereby making the floating member 242 float up and down, so that the floating member 242 drives the connecting member 2411 to rotate, thereby driving the sealing unit 120 to open the drain port 111 or close the drain port 111.

[0091] Reference Figure 3 , Figure 6 , Fig. 9 and Fig.10As shown, in a specific implementation, the transmission unit 241 also includes a second movable member 2412 and a second elastic member 2413, the shell 210 has a avoidance hole 211, the second movable member 2412 is rotatably connected to the end of the connecting member 2411 away from the drain outlet 111, the second movable member 2412 is movably arranged in the avoidance hole 211, the second elastic member 2413 is sleeved on the second movable member 2412, and the two ends of the second elastic member 2413 in the elastic force direction are connected to the second movable member 2412 and the shell 210.

[0092] In this way, the floating member 242 contacts the second moving member 2412, and the floating member 242 can generate a force on the end of the connecting member 2411 away from the drain outlet 111. When the liquid level in the water storage tank 2221 is low, the elastic force of the second elastic member 2413 is greater than the buoyancy of the liquid on the floating member 242. The combined force of the elastic force of the second elastic member 2413 and the buoyancy of the liquid on the floating member 242 is downward, and the combined force causes the connecting member 2411 to rotate, thereby causing the connecting member 2411 to move upward toward one end of the drain outlet 111, and then lift up the first moving member 122, so that The sealing member 121 opens the drain port 111. When the liquid level in the water storage tank 2221 is high, the buoyancy of the liquid on the floating member 242 is greater than the elastic force of the second elastic member 2413. The combined force of the buoyancy of the liquid on the floating member 242 and the elastic force of the second elastic member 2413 is upward, and the combined force causes the connecting member 2411 to rotate, thereby causing the connecting member 2411 to move downward toward one end of the drain port 111, thereby causing the connecting member 2411 to break contact with the first movable member 122, and the sealing member 121 closes the drain port 111 under the elastic force of the first elastic member 123.

[0093] Reference Fig. 9 As shown, in a specific implementation, the connecting member 2411 includes a lifting portion 2411a, a first rotating connection portion 2411b and a second rotating connection portion 2411c that are interconnected, the first rotating connection portion 2411b is located between the lifting portion 2411a and the second rotating connection portion 2411c, the first rotating connection portion 2411b is rotatably connected to the shell 210, the second movable member 2412 is rotatably connected to the second rotating connection portion 2411c, and the lifting portion 2411a is constructed to abut against the sealing unit 120.

[0094] In this way, the connecting member 2411 can be rotated on the shell 210 through the first rotating connection part 2411b, so that the connecting member 2411 acts as a lever. When the connecting member 2411 rotates, the end of the connecting member 2411 facing the drain outlet 111 can lift the first movable member 122 through the lifting part 2411a, thereby driving the sealing member 121 to open the drain outlet 111, and the end of the connecting member 2411 away from the drain outlet 111 can be rotatably connected to the second movable member 2412 through the second rotating connection part 2411c, so that when the connecting member 2411 rotates, the second movable member 2412 can move back and forth relative to the avoidance hole 211.

[0095] Reference Fig. 9 As shown, in a possible implementation, the transmission unit 241 further includes a rotatable connection base 2414 , the rotatable connection base 2414 is connected to the housing 210 , and the connecting member 2411 is rotatably connected to the rotatable connection base 2414 .

[0096] In this way, the first rotating connection part 2411b can be rotatably connected to the rotating connection seat 2414, and the rotating connection seat 2414 is installed on the shell 210, so that the connecting member 2411 is rotatably set on the shell 210, so that the connecting member 2411 can rotate under the combined action of the buoyancy of the floating member 242 and the elastic force of the second elastic member 2413.

[0097] Reference Figure 5 and Figure 7 As shown, in a possible implementation, the liquid level control assembly 240 further includes a mounting seat 244 , which is located between the water tank 110 and the housing 210 , the mounting seat 244 is connected to the housing 210 , and the rotatable connecting seat 2414 is rotatably connected to the mounting seat 244 .

[0098] That is to say, in order to facilitate assembly, during installation, the connecting member 2411 can be rotatably connected to the rotating connecting seat 2414 through the first rotating connecting portion 2411b, the rotating connecting seat 2414 is connected to the mounting seat 244, and the mounting seat 244 is connected to the shell 210. In this way, the connecting member 2411 can be rotatably set on the shell 210.

[0099] Reference Figure 7 and Figure 8 As shown, in some embodiments, the mounting seat 244 has a first connecting hole 2441 , the housing 210 has a second connecting hole 212 , and the water outlet 111 , the first connecting hole 2441 , and the second connecting hole 212 are sequentially connected between the water tank 110 and the wet curtain unit 221 .

[0100] It can be understood that since the mounting seat 244 is arranged between the water tank 110 and the shell 210, so that the transmission unit 241 can be installed to the shell 210 through the mounting seat 244, the top wall of the shell 210 is located between the wet curtain unit 221 and the mounting seat 244. If the mounting seat 244 is not provided with the first connecting hole 2441 and the shell 210 is not provided with the second connecting hole 212, the water outlet 111 cannot be directly connected to the wet curtain unit 221. Therefore, by providing the first connecting hole 2441 on the mounting seat 244 and the second connecting hole 212 on the shell 210, the water outlet 111, the first connecting hole 2441 and the second connecting hole 212 are connected in sequence, so that the liquid in the water tank 110 can flow through the water outlet 111, the first connecting hole 2441 and the second connecting hole 212 in sequence to reach the top of the wet curtain unit 221.

[0101] Reference Figure 6 and Figure 7 As shown, in a possible implementation, the shell 210 has a mist outlet 213 at one end facing the water tank 110 , and the shell 210 has an air inlet 214 at the bottom facing away from the water tank 110 .

[0102] In this way, when the fan assembly 230 is in operation, it drives the external air into the shell 210 from the bottom of the shell 210, and then flows upward through the wet curtain 2211, thereby evaporating the liquid on the wet curtain 2211 to form wet mist, and finally blown out through the mist outlet 213. Since the wet curtain assembly 220 is located above the fan assembly 230, this air flow method is more in line with the positional relationship between the wet curtain assembly 220 and the fan assembly 230.

[0103] Reference Figure 6 and Figure 7 As shown, in some embodiments, the water receiving tray 222 has a vent 2222, which is located on the inner side of the water storage tank 2221, and multiple vents 2222 are arranged at intervals along the circumference of the water storage tank 2221, and the vent 2222 connects the wet curtain unit 221 and the fan assembly 230.

[0104] In this way, after the fan assembly 230 sucks in the external air, the air continues to flow upward to the water receiving tray 222, and then enters the inner side of the wet curtain 2211 through the vent 2222 of the water receiving tray 222. After passing through the wet curtain 2211, the air enters the outer side of the wet curtain 2211, thereby accelerating the evaporation of the liquid on the wet curtain 2211, thereby forming a wet mist outflow.

[0105] Reference Figure 2 As shown, in a specific implementation, the water tank 110 includes a box body 112 and a box cover 113 . The box body 112 has a water inlet 1121 at one end away from the humidification host 200 , and the box cover 113 is detachably connected to the water inlet 1121 .

[0106] With such a configuration, when the liquid in the water tank 110 is insufficient, the tank cover 113 can be directly opened to add water to the box body 112. At this time, the water tank 110 does not need to be removed from the humidifier host 200, and it is more convenient to add water to the water tank 110. Alternatively, the water tank 110 can be removed from the humidifier host 200, and then the tank cover 113 can be opened to add water to the box body 112. After adding water, the tank cover 113 can be closed to prevent foreign matter from entering the water tank 110.

[0107] Specifically, to facilitate processing and assembly, the shell 210 may include a first shell 210a and a second shell 210b, the first shell 210a is connected to one end of the second shell 210b facing the water tank 110, the avoidance hole 211, the second connecting hole 212, and the mist outlet 213 are all located in the first shell 210a, and the air inlet 214 is located in the second shell 210b.

[0108] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
