Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a humidifier. Background Technology

[0002] As people's living standards improve, the widespread use of air conditioning has led to the emergence of "air conditioning sickness," such as tight skin, dry mouth, coughs, and colds. Scientific evidence shows that air humidity is closely related to human health and daily life. Therefore, various types of humidifiers are used to increase indoor air humidity. Evaporative humidifiers, in particular, use a fan to force air through a water-absorbing medium such as a wet curtain, causing it to come into contact with water and release moisture, thus blowing a moist airflow into the room and increasing ambient humidity.

[0003] Most existing evaporative humidifiers still use an externally detachable water tank structure. When water needs to be added, the water tank must be removed, filled with water, and then reinstalled. The water replenishment process is time-consuming and laborious. In addition, excess liquid on the wet curtain drips into the water tank under the action of gravity, and the contact between the liquid in the water tank and the liquid in the tank generates a lot of noise, which will lead to a poor user experience. Utility Model Content

[0004] Therefore, it is necessary to provide a humidifier that addresses the problem that some existing humidifiers require disassembling the water tank for refilling, which is inconvenient.

[0005] A humidifier includes: a main unit with a water inlet at its top, an air inlet, and an air outlet; a evaporative cooling pad assembly disposed within the main unit; a water tank disposed at the bottom of the main unit, the water tank having a liquid storage chamber; a liquid supply assembly, at least a portion of which is disposed within the liquid storage chamber, the liquid supply assembly being used to draw liquid from the liquid storage chamber and deliver it to the evaporative cooling pad assembly; a fan assembly disposed within the main unit, the fan assembly being used to drive air into the main unit through the air inlet, flow through the evaporative cooling pad assembly, and then output it outward through the air outlet; and a filter assembly disposed on the water tank. The main unit also includes a pipe assembly, one end of which is connected to the water inlet, and the other end of which extends downward along the height of the main unit into the water tank. The filter assembly is used to connect the pipe assembly to the liquid storage chamber and to filter the liquid.

[0006] This application provides a humidifier with a water tank at the bottom of the main unit for storing humidifying liquid. The main unit contains a evaporative cooling pad assembly and a fan assembly. When the humidifier is activated, the liquid supply assembly draws liquid from the water tank and supplies it to the evaporative cooling pad assembly. Driven by the fan assembly, indoor air enters the main unit and, through the evaporative cooling pad assembly, carries away some of the liquid before being discharged back into the room, thus increasing indoor humidity. The top of the main unit has a liquid inlet connected to the water tank's storage chamber via a pipe assembly. When water needs to be added, the user can directly add liquid to the storage tank through the inlet, avoiding the need for disassembling and installing the water tank, making filling simpler and easier. Simultaneously, a filter assembly is installed between the pipe assembly and the storage chamber. As the liquid flows through the filter assembly, dust and bacteria contaminating the liquid are purified, improving its cleanliness. The filter assembly also reduces the liquid flow speed, preventing direct collisions between the liquid flowing from the pipe assembly and the liquid in the storage chamber, thus avoiding excessive noise and improving the user experience.

[0007] In one embodiment, the water tank includes a tank body and a water collection tray. The tank body has the liquid storage chamber, and the water collection tray is disposed between the tank body and the evaporative cooling pad assembly. The side of the water collection tray facing the evaporative cooling pad assembly is recessed to form a water collection trough, and the bottom of the water collection trough has a return hole communicating with the liquid storage chamber. By adopting the above structure, the liquid flowing out of the evaporative cooling pad assembly will enter the water collection trough under the action of gravity and can flow back to the water tank for recycling through the return hole, achieving the effect of environmental protection and energy saving. The water collection tray can effectively concentrate and guide the liquid flowing out of the evaporative cooling pad assembly, avoiding the direct contact between the liquid dripping from the evaporative cooling pad assembly and the liquid in the liquid storage chamber, which would generate significant noise.

[0008] In one embodiment, the filter assembly includes a mounting housing and a filter body. The mounting housing is disposed within the housing and has a receiving cavity. The mounting housing has an inlet and an outlet. The end of the pipe assembly away from the inlet extends downward along the height direction of the main unit to the inlet. The pipe assembly, the inlet, the receiving cavity, the outlet, and the storage cavity are sequentially connected. The filter body is fitted and installed into the receiving cavity. By adopting the above structure, using the mounting housing to connect the pipe assembly and the storage cavity, it can be ensured that the liquid falling from the pipe assembly can fully enter the pipe assembly and contact the filter body to achieve filtration and purification. Further, the filter body includes a filter sponge. The filter sponge has a dense porous structure and a high surface area, which can effectively block and trap impurities and particulate matter in liquids or gases, improving the cleanliness of the flowing medium. At the same time, the high density and porous structure of the sponge material allows the sound wave energy generated during the medium flow to be consumed inside the material, thereby reducing the propagation and reflection of noise.

[0009] In one embodiment, the reflux hole is connected to the liquid storage chamber through the filter assembly. After prolonged use, the evaporative cooling pad assembly will absorb a large amount of dust and bacteria from the air. If the user fails to clean it regularly, it will affect the water quality and may even lead to mold growth and unpleasant odors in the evaporative cooling pad assembly, posing a threat to people's health. By adopting the above structure, the liquid flowing out of the evaporative cooling pad assembly falls into the water collection tank under gravity. The liquid then passes through the filter assembly, purifying and filtering out the dust and bacteria it carried, thereby improving the cleanliness of the liquid and the evaporative cooling pad assembly and effectively extending the service life of the evaporative cooling pad assembly. In addition, the filter assembly greatly reduces the flow speed of the liquid flowing out of the reflux hole, avoiding direct collision with the liquid in the liquid storage chamber and generating significant noise, thus improving the user experience.

[0010] In one embodiment, the side wall of the mounting housing with an inlet is adapted to and connected to the outer bottom wall of the water collection tray. The inlet is located below the reflux hole and communicates with it. By adopting this configuration, the liquid flowing out of the reflux hole will directly enter the inlet under gravity, and the direct connection between the mounting housing and the bottom wall of the water collection tray prevents liquid from entering the storage chamber directly through the gap between the mounting housing and the water collection tray without being adequately filtered.

[0011] In one embodiment, the top of the housing has an installation port communicating with the liquid storage chamber. The water collection tray is fitted to the installation port, and the outer peripheral wall of the water collection tray is recessed inward to form a clearance groove. The end of the pipe assembly away from the water inlet extends through the clearance groove into the water tank and connects to the filter assembly. By providing an installation port that fits the water collection tray, the installation and disassembly of the water collection tray and the housing are made more convenient. At the same time, the clearance groove on the water collection tray also facilitates the arrangement of the pipe assembly, making the positioning and assembly of the pipe assembly more convenient and faster.

[0012] In one embodiment, the mounting housing has a first snap-fit ​​for connecting to the housing. The first snap-fit ​​ensures stable mounting of the filter assembly on the housing, preventing displacement of the filter assembly during humidifier movement and thus maintaining filtration efficiency. Furthermore, the snap-fit ​​connection allows for tool-free disassembly of the filter assembly, greatly simplifying replacement and cleaning for users.

[0013] In one embodiment, the mounting housing is disposed in the liquid storage cavity, and the side of the mounting housing near the inner wall of the liquid storage cavity protrudes upward to form the first buckle, which engages with the edge of the mounting opening.

[0014] In one embodiment, the end of the pipe assembly away from the water inlet extends downward along the height of the main unit into the water collection tray and communicates with the water collection trough. The filter assembly is disposed in the water collection trough, located between the pipe assembly and the return hole. By adopting the above structure, the filter assembly can simultaneously filter and clean the liquid flowing from both the pipe assembly and the evaporative cooling pad assembly. Furthermore, placing the filter assembly in the water collection trough avoids occupying space in the liquid storage chamber, which helps to increase the water storage capacity of the tank.

[0015] In one embodiment, the bottom wall of the water collection tank is recessed to form a limiting groove, and the bottom wall of the limiting groove has the return hole. The bottom of the filter assembly is adapted to the limiting groove for installation. Specifically, the filter assembly includes a filter sponge. By adopting the above structure, the filter sponge is adapted to be installed in the positioning groove, which facilitates its fixation and prevents it from shifting. Furthermore, the horizontal height of the bottom wall of the limiting groove is lower than the horizontal height of the bottom wall of the water collection tank, thereby ensuring that when the liquid flows to the water inlet, it can fully contact the filter sponge in the limiting groove to complete filtration and purification.

[0016] In one embodiment, the sidewall of the water collection tank is recessed to form a positioning groove, and the end of the pipe assembly away from the water inlet extends into the positioning groove. The positioning groove facilitates the positioning of the pipe assembly and prevents interference between the pipe assembly and the evaporative cooling pad assembly.

[0017] In one embodiment, the water tank further includes a flow guide portion disposed in the liquid storage chamber. The flow guide portion forms a flow guiding surface that extends from below the return hole towards the bottom wall of the liquid storage chamber. By providing the flow guide portion, its flow guiding surface provides buffering and guidance for the liquid flowing out through the return hole, preventing the liquid from dripping directly onto the tank body under gravity and directly contacting the liquid in the liquid storage chamber, thus avoiding significant noise and improving the user experience.

[0018] In one embodiment, the guide surface includes a first guide surface and a second guide surface. The first guide surface is disposed opposite to the outer bottom wall of the water collection tray, and a flow cavity is formed between the first guide surface and the outer bottom wall of the water collection tray. The flow cavity connects the return hole and the liquid storage cavity respectively. The second guide surface extends from the first guide surface towards the bottom wall of the liquid storage cavity. By adopting the above structure, the liquid flowing out of the water inlet will fall into the bottom of the liquid storage cavity through the first guide surface and the second guide surface in sequence, so that the liquid is effectively buffered. At the same time, the flow cavity formed by the first guide surface and the outer bottom wall of the water collection tray can shield the liquid flowing out of the water inlet, preventing the liquid from splashing when it collides with the first guide surface, forming dispersed water droplets, and falling into the liquid storage cavity through the gap between the water collection tray and the first guide surface, which would generate a lot of noise.

[0019] In one embodiment, the fan assembly, the evaporative cooling pad assembly, and the water tank are arranged from top to bottom. The pipe assembly includes a first pipe and a second pipe. The first pipe is located on the outer periphery of the fan assembly, and the second pipe is located on the outer periphery of the evaporative cooling pad assembly. Both ends of the first pipe are connected to the water inlet and the second pipe, respectively. The end of the second pipe away from the first pipe extends downward into the water tank. The pipe assembly consists of two sub-pipes, the first and second pipes, which facilitates easier assembly of the pipe assembly with the main unit and its internal components. Furthermore, the fan assembly includes a fan and a volute. The fan is housed within the volute, which is integrally formed with the first pipe. By adopting the above structure, the connection between the first pipe and the water inlet and / or the second pipe can be completed simultaneously during the assembly of the fan assembly with the main unit and other components, thereby simplifying the assembly steps of the pipe assembly.

[0020] In one embodiment, the main unit includes a housing and a top cover. The top cover has a recessed center forming a water collection trough, and the bottom of the water collection trough is provided with the water inlet. By adopting the above structure, when the user adds liquid directly to the water tank through the liquid inlet of the top cover, the water collection trough formed by the top cover can provide a buffer space for liquid injection, thereby saving the user's liquid injection operation and waiting time.

[0021] In one embodiment, the top cover is formed with a connector that is connected to the first pipe and connects the water inlet and the first pipe.

[0022] In one embodiment, one of the second pipe and the main unit is provided with a second buckle, and the other of the second pipe and the main unit is provided with a slot, in which the second buckle is engaged. The second buckle ensures the stable mounting of the second pipe on the main unit, preventing the second pipe from shifting during humidifier movement. Furthermore, the buckle connection allows for tool-free disassembly of the second pipe, greatly facilitating cleaning and maintenance by the user. Attached Figure Description

[0040] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0041] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0042] The humidifier of some embodiments of the present invention is described below with reference to the accompanying drawings.

[0043] like Figures 1 to 3 As shown, this embodiment discloses a humidifier, including: a main unit 1, with a water inlet 101 on the top, an air inlet 102, and an air outlet 103; a wet curtain assembly 2, disposed inside the main unit 1; a water tank 3, disposed at the bottom of the main unit 1, with a liquid storage chamber 301; a liquid supply assembly 4, at least a portion of which is disposed in the liquid storage chamber 301, the liquid supply assembly 4 being used to extract liquid from the liquid storage chamber 301 and transport it to the wet curtain assembly 2; and a fan assembly 5. The fan assembly 5 is installed inside the main unit 1. The fan assembly 5 is used to drive air into the main unit 1 through the air inlet 102, and after flowing through the wet curtain assembly 2, it is output to the outside through the air outlet 103. The filter assembly 6 is installed on the water tank 3. The main unit 1 is provided with a pipe assembly 7. One end of the pipe assembly 7 is connected to the water inlet 101, and the other end of the pipe assembly 7 extends downward along the height direction of the main unit 1 into the water tank 3. The filter assembly 6 is used to connect the pipe assembly 7 to the liquid storage chamber 301 and can filter the liquid.

[0044] This application provides a humidifier, in which a water tank 3 is provided at the bottom of the main unit 1 for storing humidifying liquid. The main unit 1 is provided with a wet curtain assembly 2 and a fan assembly 5. When the humidifier is started, the liquid supply assembly 4 draws liquid from the water tank 3 and supplies it to the wet curtain assembly 2. Driven by the fan assembly 5, indoor air enters the main unit 1 and carries away some of the liquid through the wet curtain assembly 2 before being discharged back into the room, thereby achieving the purpose of increasing indoor humidity. The main unit 1 of this device has a liquid inlet on its top, which is connected to the liquid storage chamber 301 of the water tank 3 through the pipe assembly 7. When water needs to be added to the water tank 3, the user can directly add the liquid to the storage tank through the liquid inlet, thus avoiding the disassembly and installation of the water tank 3 and making water filling simpler and easier. At the same time, a filter assembly 6 is provided between the pipe assembly 7 and the liquid storage chamber 301. When the liquid flows through the filter assembly 6, the dust and bacteria contaminated in the liquid can be purified and filtered, thereby improving the cleanliness of the liquid. At the same time, the filter assembly 6 can reduce the speed of the liquid flow, avoiding direct collision between the liquid flowing out of the pipe assembly 7 and the liquid in the liquid storage chamber 301, which would generate a lot of noise and improve the user experience.

[0045] like Figures 3 to 9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the water tank 3 includes a tank body 31 and a water collection tray 32. The tank body 31 is provided with a liquid storage chamber 301. The water collection tray 32 is disposed between the tank body 31 and the wet curtain assembly 2. The side of the water collection tray 32 facing the wet curtain assembly 2 is recessed to form a water collection trough 302. The bottom of the water collection trough 302 is provided with a return hole 303 communicating with the liquid storage chamber 301. By adopting the above structure, the liquid flowing out of the wet curtain assembly 2 will enter the water collection trough 302 under the action of gravity, and can be returned to the water tank 3 for recycling through the return hole 303, achieving the effect of environmental protection and energy saving. The water collection tray 32 can effectively concentrate and guide the liquid flowing out of the wet curtain assembly 2, which can avoid the liquid dripping from the wet curtain assembly 2 from directly entering the water tank 3 and contacting the liquid in the liquid storage chamber 301, thus avoiding the generation of large noise.

[0046] like Figures 3 to 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the filter assembly 6 includes a mounting housing 61 and a filter body 62. The mounting housing 61 is disposed in the housing 31 and has a receiving cavity. The mounting housing 61 has a water inlet 601 and a water outlet 602. The end of the pipe assembly 7 away from the water inlet 101 extends downward along the height direction of the main unit 1 to the water inlet 601. The pipe assembly 7, the water inlet 601, the receiving cavity, the water outlet 602, and the liquid storage cavity 301 are sequentially connected. The filter body 62 is fitted and installed in accordance with the receiving cavity. By adopting the above structure, the mounting housing 61 connects the pipe assembly 7 and the liquid storage cavity 301, ensuring that the liquid falling from the pipe assembly 7 can fully enter the pipe assembly 7 and contact the filter body 62 to achieve filtration and purification. Further, the filter body 62 includes a filter sponge. Filter sponges have a dense porous structure and high surface area, which can effectively block and trap impurities and particles in liquids or gases, improving the cleanliness of the medium flowing through them. At the same time, the high density and porous structure of the sponge material allows the sound wave energy generated during the flow of the medium to be consumed inside the material, thereby reducing the propagation and reflection of noise.

[0047] like Figure 3As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the return hole 303 is connected to the liquid storage chamber 301 through the filter assembly 6. After prolonged use of the humidifier, the wet curtain assembly 2 will absorb a large amount of dust and bacteria from the air. If the user fails to clean it regularly in time, it will affect the water quality and even cause the wet curtain assembly 2 to mold and emit odors, posing a threat to people's health. By adopting the above structure, the liquid flowing out of the wet curtain assembly 2 falls into the water collection tank 302 under the action of gravity. The liquid will then pass through the filter assembly 6 to purify and filter the dust and bacteria it carries, thereby improving the cleanliness of the liquid and the wet curtain assembly 2 and effectively extending the service life of the wet curtain assembly 2. In addition, the setting of the filter assembly 6 can greatly reduce the flow speed of the liquid flowing out of the return hole 303, avoiding direct collision with the liquid in the liquid storage chamber 301 and generating greater noise, thereby improving the user experience.

[0048] like Figures 3 to 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the side wall of the mounting housing 61 with an inlet 601 is adapted to and connected to the outer bottom wall of the water collection tray 32, the inlet 601 is located below the return hole 303, and the inlet 601 communicates with the return hole 303. By adopting the above configuration, the liquid flowing out of the return hole 303 will directly enter the inlet 601 under the action of gravity, and the mounting housing 61 is directly connected to the bottom wall of the water collection tray 32, which can prevent the liquid from directly entering the liquid storage chamber 301 through the gap between the mounting housing 61 and the water collection tray 32 without being adequately filtered.

[0049] like Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the top of the housing 31 is provided with an installation port 304 communicating with the liquid storage chamber 301; the water collection tray 32 is adapted to be installed with the installation port 304; the outer peripheral wall of the water collection tray 32 is recessed inward to form a relief groove 305; the end of the pipe assembly 7 away from the water inlet 101 extends through the relief groove 305 into the water tank 3 and connects with the filter assembly 6. By setting the installation port 304 to be adapted to the water collection tray 32, the installation and disassembly of the water collection tray 32 and the housing 31 can be made more convenient. At the same time, the relief groove 305 on the water collection tray 32 also facilitates the arrangement of the pipe assembly 7, making the positioning and assembly of the pipe assembly 7 more convenient and faster.

[0050] like Figures 3 to 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mounting housing 61 is formed with a first buckle 611, which is used to connect the housing 31. The first buckle 611 ensures the stable mounting of the filter assembly 6 on the housing 31, preventing the filter assembly 6 from shifting during humidifier movement and affecting the filtration effect. Furthermore, the buckle connection allows for tool-free disassembly of the filter assembly 6, greatly facilitating user replacement and cleaning.

[0051] like Figures 3 to 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mounting housing 61 is disposed in the liquid storage cavity 301, the side of the mounting housing 61 near the inner wall of the liquid storage cavity 301 protrudes upward and forms a first buckle 611, and the first buckle 611 is engaged with the edge of the mounting opening 304.

[0052] like Figures 7 to 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the end of the pipe assembly 7 away from the water inlet 101 extends downward along the height direction of the main unit 1 into the water collection tray 32 and communicates with the water collection tank 302; the filter assembly 6 is disposed in the water collection tank 302, and the filter assembly 6 is located between the pipe assembly 7 and the return hole 303. By adopting the above structure, the filter assembly 6 can simultaneously filter and clean the liquid flowing out of the pipe assembly 7 and the wet curtain assembly 2, and the filter assembly 6 being disposed in the water collection tank 302 avoids occupying the space of the liquid storage chamber 301, which is beneficial to increasing the water storage capacity of the water tank 3.

[0053] like Figure 8 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the bottom wall of the water collection tank 302 is recessed to form a limiting groove 306, and the bottom wall of the limiting groove 306 is provided with a return hole 303. The bottom of the filter assembly 6 is adapted to the limiting groove 306 for installation. Specifically, the filter assembly 6 includes a filter sponge. By adopting the above structure, the filter sponge is adapted to be installed in the positioning groove 307, which facilitates its fixation and prevents it from shifting. Furthermore, the horizontal height of the bottom wall of the limiting groove 306 is lower than the horizontal height of the bottom wall of the water collection tank 302, thereby ensuring that when the liquid flows to the water inlet 101, it can fully contact the filter sponge in the limiting groove 306 to complete the filtration and purification.

[0054] like Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the side wall of the water collection tank 302 is recessed to form a positioning groove 307, and the end of the pipe assembly 7 away from the water inlet 101 extends into the positioning groove 307. The positioning groove 307 facilitates the positioning of the pipe assembly 7 and avoids interference between the pipe assembly 7 and the wet curtain assembly 2.

[0055] like Figure 8 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the water tank 3 also includes a flow guide 33, which is disposed in the liquid storage chamber 301. The flow guide 33 has a flow guide surface 331, which extends from the bottom of the return hole 303 towards the bottom wall of the liquid storage chamber 301. By providing the flow guide 33, its flow guide surface 331 provides buffering and guidance for the liquid flowing out of the return hole 303, which can prevent the liquid from dripping directly onto the tank 31 under gravity and directly contacting the liquid in the liquid storage chamber 301, thus avoiding significant noise and improving the user experience.

[0056] like Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the flow guiding surface 331 includes a first flow guiding surface 3311 and a second flow guiding surface 3312. The first flow guiding surface 3311 is disposed opposite to the outer bottom wall of the water collecting tray 32. The first flow guiding surface 3311 and the outer bottom wall of the water collecting tray 32 cooperate to form a flow passage cavity 308. The flow passage cavity 308 is connected to the return hole 303 and the liquid storage cavity 301 respectively. The second flow guiding surface 3312 extends from the first flow guiding surface 3311 toward the bottom wall near the liquid storage cavity 301. By adopting the above structure, the liquid flowing out of the water inlet 101 will fall into the bottom of the liquid storage cavity 301 through the first guide surface 3311 and the second guide surface 3312 in sequence, so that the liquid is effectively buffered. At the same time, the first guide surface 3311 and the outer bottom wall of the water collection plate 32 form a flow cavity 308, which can shield the liquid flowing out of the water inlet 101, preventing the liquid from splashing when it collides with the first guide surface 3311, forming dispersed water droplets, and falling into the liquid storage cavity 301 through the gap between the water collection plate 32 and the first guide surface 3311, which would generate a lot of noise.

[0057] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the fan assembly 5, the wet curtain assembly 2, and the water tank 3 are arranged from top to bottom; the pipe assembly 7 includes a first pipe 71 and a second pipe 72; the first pipe 71 is disposed on the outer periphery of the fan assembly 5, and the second pipe 72 is disposed on the outer periphery of the wet curtain assembly 2; both ends of the first pipe 71 are connected to the water inlet 101 and the second pipe 72, respectively; and the end of the second pipe 72 away from the first pipe 71 extends downward into the water tank 3. The pipe assembly 7 is composed of two sub-pipes, the first pipe 71 and the second pipe 72, which makes the assembly of the pipe assembly 7 with the main unit 1 and the internal components of the main unit 1 easier. Furthermore, the fan assembly 5 includes a fan 51 and a volute 52; the fan 51 is disposed in the volute 52, and the volute 52 and the first pipe 71 are integrally formed. By adopting the above structure, the connection between the first pipe 71 and the water inlet 101 and / or the second pipe 72 can be completed simultaneously during the assembly of components such as the fan assembly 5 and the main unit 1, thereby simplifying the assembly steps of the pipe assembly 7.

[0058] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the main unit 1 includes a housing 11 and a top cover 12, the middle of the top cover 12 is recessed to form a water collection groove 104, and the bottom of the water collection groove 104 is provided with a water inlet 101. By adopting the above structure, when the user adds liquid directly to the water tank 3 through the liquid inlet of the top cover 12, the water collection groove 104 formed by the top cover 12 can provide a buffer space for liquid injection, thereby saving the user's liquid injection operation and waiting time.
