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

[0002] With the improvement of people's living standards and the pursuit of a healthy environment, humidifiers have become a necessity for many families. Humidifiers use humidifying components to humidify and ventilate, thereby increasing the humidity of indoor air and improving the comfort of the living environment.

[0003] After prolonged use, scale or other contaminants can easily form in the water circuit components of a humidifier, especially in areas with hard water. Frequent cleaning of the water circuit components, particularly the water pump, is necessary; otherwise, the scale buildup in the pump will affect its performance.

[0004] However, in related technologies, the water pump of the humidifier is located in the water tank, or the water pump cannot be removed from the water tank, or the process of removing it from the water tank is cumbersome, which makes it impossible to clean the water pump thoroughly, thus affecting the working performance of the water pump. Utility Model Content

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.

[0058] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0059] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; 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, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0060] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0061] Please refer to the following: Figures 1 to 2 This application provides a humidifier 100. The humidifier 100 includes a housing 1, within which a receiving cavity is formed. A humidification assembly 3, a fan assembly 5, and a water circuit assembly 4 are disposed within the receiving cavity. A water tank 2 can be placed inside the housing 1 or outside the housing 1, for example, the housing 1 can overlap the top of the water tank 2.

[0062] like Figure 1 As shown, the housing 1 includes an air inlet 11 and an air outlet 12. The air inlet 11 is located on the side wall of the housing 1 and corresponds to the humidification component 3. The air outlet 12 is located on the top of the housing 1, and an airflow channel 1a is formed between the air inlet 11 and the air outlet 12.

[0063] like Figure 2As shown, the humidification component 3 and the fan component 5 are located in the airflow channel 1a. The airflow entering the casing 1 from the air inlet 11 forms a humidified airflow after passing through the humidification component 3, and then passes through the fan component 5 and is discharged from the air outlet 12.

[0064] The housing 1 can be the exterior part of the humidifier 100, and provide structural support and protection for the structural parts and electrical components (e.g., fan assembly 5) of the humidifier 100.

[0065] In some embodiments, such as Figure 2 As shown, the water tank 2 is located at the bottom of the humidifier 100. The humidification component 3 is detachably mounted on the water tank 2.

[0066] In some embodiments, the humidification component 3 may include a mesh fabric 32. The mesh fabric 32, also known as a wet curtain, comprises a wettable filter material made of hydrophilic polymer composite material or natural / synthetic fiber fabric. The surface of the wettable filter material may be treated with a nano-coating or gradient porosity to optimize capillary water absorption performance. The wettable filter material forms a high specific surface area air-water contact interface through a multi-layer composite or three-dimensional honeycomb structure, and is configured with an antibacterial agent or anti-mildew coating to resist biofouling. The wettable filter material may be equipped with a support frame integrating guide channels or asymmetric corrugated units to directionally guide airflow and moisture diffusion paths. Simultaneously, the mesh fabric 32 can be a modular assembly structure of the wettable substrate, adaptable to the detachable installation interface of different air supply systems.

[0067] In some embodiments, such as Figure 2 As shown, the water circuit assembly 4 is located inside the housing 1. The water circuit assembly 4 is used to transport water from the water tank 2 to the humidification assembly 3. After the humidification assembly 3 is humidified, it can provide moisture to the airflow passing through the humidification assembly 3. The humidified airflow can be pressurized and accelerated by the fan assembly 5 and then flow from the humidifier 100 into the indoor environment to achieve the humidification function of the humidifier 100.

[0068] In some embodiments, such as Figure 3 and Figure 4 As shown, the water system assembly 4 may include a bracket 41. The bracket 41 is disposed inside the housing 1. Figure 2 As shown, the middle of the water tank 2 is hollowed out to allow the water circuit assembly 4 to be inserted into or removed from the water tank 2. The water circuit assembly 4 and the water tank 2 can be connected without disassembly, so that the water circuit assembly 4 can be separated from the water tank 2.

[0069] like Figure 2 As shown, when the housing 1 is fitted onto the outside of the water tank 2, at least a portion of the bracket 41 can extend into the inner cavity of the humidification assembly 3 and the interior of the water tank 2. (For example, the portion of the bracket 41 with the heating tube 411 is located outside the water tank 2).

[0070] In some embodiments, such as Figure 3and Figure 4 As shown, the water circuit assembly 4 may include a water pump assembly 42. The water pump assembly 42 can move synchronously with the bracket 41 and the housing 1. When the housing 1 is mounted outside the water tank 2, the water pump assembly 42 of the water circuit assembly 4 can extend into the water tank 2 to draw water from the water tank 2 and spray it into the humidification assembly 3. When it is necessary to clean the water pump assembly 42, the housing 1 can be lifted upwards, and the water pump assembly 42 can be removed from the water tank 2.

[0071] In some embodiments, such as Figure 10 As shown, the water circuit assembly 4 is disposed inside the housing 1. Specifically, the bracket 41 of the water circuit assembly 4 is detachably disposed on the top of the water tank 2, the humidification assembly 3 is detachably disposed on the bracket 41, and the water pump assembly 42 in the water circuit assembly 4 can be located inside the water tank 2 inside the housing 1.

[0072] In some embodiments, such as Figure 4 and Figure 10 As shown, the water pump assembly 42 is detachably connected to the bracket 41. This allows the water pump assembly 42 to be removed from the bracket 41 for thorough cleaning when cleaning is required. Thus, the humidifier 100 provided in this application, by separating the water circuit assembly 4 from the water tank 2 and allowing the water pump assembly 42 to be detachably connected relative to the bracket 41, enables users to easily and thoroughly clean the water pump assembly 42, solving the problem of difficult-to-clean water pumps in humidifiers 100 in related technologies. While improving the efficiency and stability of the humidifier 100, it also optimizes the user experience, reduces performance degradation and failure rate caused by scale accumulation, and achieves a good and continuous humidification effect.

[0073] In some embodiments, such as Figure 2 and Figure 10 As shown, the water tank 2 is at least partially connected to the humidification component 3 so that water overflowing from the humidification component 3 flows back to the water tank 2.

[0074] In some embodiments, such as Figure 2 As shown, the bottom of the housing 1 is open, and the housing 1 is fitted onto the outside of the water tank 2 through the open end, and is separable from the water tank 2. The housing 1 covers the outside of the water tank 2 by fitting, and there may be an assembly gap between the housing 1 and the water tank 2, or the housing 1 may contact at least part of the outer wall of the water tank 2 and form an abutment relationship to increase the structural stability between the housing 1 and the water tank 2.

[0075] In some embodiments, such as Figure 2As shown, the water circuit assembly 4 is located in the central area of ​​the humidifier 100. Since the water circuit assembly 4 has a certain weight, if the water circuit assembly 4 is off-center, it will cause the center of gravity of the humidifier 100 to shift. By placing the water circuit assembly 4 in the central area of ​​the humidifier 100, the overall center of gravity of the humidifier 100 will be more balanced and stable, and it will not be easy for it to tilt or tip over.

[0076] Furthermore, the water path assembly 4 can extend from the central region of the humidifier 100 into the opening in the middle of the water tank 2, and draw water from the water tank 2 and spray it into the humidifier assembly 3. Unlike the related technology where the water path assembly 4 of the humidifier 100 is located on the outer periphery of the humidifier assembly 3, that is, the water path assembly 4 is located between the humidifier assembly 3 and the air inlet 11, the water path assembly 4 in this embodiment is set in the central region of the humidifier 100 so as not to block the air inlet 11, thereby increasing the flow rate of airflow from the air inlet 11 into the airflow channel 1a.

[0077] In some embodiments, such as Figure 2 and Figure 9 As shown, the housing 1 may include a partition 13. A water circuit assembly 4 is disposed on the partition 13. A humidification assembly 3 and a water tank 2 are located on one side of the partition 13, and a fan assembly 5 is located on the other side of the partition 13.

[0078] The fan assembly 5 is located on one side of the partition 13, and the humidification assembly 3 and the water tank 2 are located on the other side of the partition 13. The water circuit assembly 4 is disposed on the partition 13 and extends toward the water tank 2. The partition 13 can further isolate the fan assembly 5 from the water to optimize the water and electricity separation design of the humidifier 100.

[0079] In some embodiments, such as Figure 3 and Figure 4 As shown, the humidifier 100 also includes a ventilation grille 49. The ventilation grille 49 is connected to the air inlet of the fan assembly 5. The ventilation grille 49 is provided with a vent, which connects to the air inlet 11 and the air outlet 12.

[0080] It is understandable that the impeller 52 in the fan assembly 5 generates negative pressure during rotation, and the fan assembly 5 and humidification assembly 3 are located on opposite sides of the partition 13. The ventilation grille 49 is connected to the area with strong negative pressure at the air inlet of the fan assembly 5, and the air pressure generated by the negative pressure suction is concentrated in the ventilation grille 49. Thus, the ventilation grille 49 can effectively guide the airflow towards the fan assembly 5, allowing the humidified airflow to enter the fan assembly 5 at a higher speed and pressure. The fan assembly 5 further accelerates and pressurizes the airflow, enabling the humidified airflow to exit the humidifier 100 from the air outlet 12 with a greater head and more uniform diffusion effect, thereby improving the humidification range of the humidifier 100 and the uniformity of indoor air humidity.

[0081] Furthermore, when it is necessary to clean the water tank 2 and the humidification component 3, the water circuit component 4 can be separated from the water tank 2 by lifting the casing 1 upwards. As long as the shape and size of the air inlet are properly set, the ventilation grille 49 located at the air inlet of the fan component 5 can block the user's fingers, preventing the user's fingers from accidentally sticking into the fan component 5, thereby improving the safety of using the humidifier 100.

[0082] In some embodiments, the ventilation grille 49 is integrally formed with the bracket 41. In this way, the water circuit assembly 4 is not only used to supply water to the humidification assembly 3, but also serves as a structural component to connect the airflow channel 1a, simplifying the structural component data within the humidifier 100 and achieving a compact design of the humidifier 100.

[0083] In some embodiments, such as Figure 3 and Figure 4 As shown, the ventilation grille 49 surrounds the entire outer periphery of the bracket 41.

[0084] In this way, the ventilation grille 49 can provide full ventilation along the circumference of the humidifier 100, which can reduce vibration or noise caused by uneven airflow distribution and improve the user experience.

[0085] In some embodiments, the ventilation grille 49 may be connected to the air inlet of the partition 13 and the fan assembly 5, respectively.

[0086] like Figure 2 As shown, the fan assembly 5 may include a fan housing 51. A ventilation grille 49 may be connected to the air inlet of the fan housing 51 to increase the airflow rate entering the fan assembly 5 from the ventilation grille 49 and reduce airflow loss. The ventilation grille 49 may be connected to both the partition plate 13 and the fan assembly 5 to further reduce airflow loss when air flows into the fan assembly 5.

[0087] In some embodiments, such as Figure 2 As shown, there is no need for a disassembly connection structure (such as snap-fit ​​or locking connections) between the housing 1 and the water tank 2. This allows for easy separation of the water tank 2 from the housing 1 by simply lifting the housing 1, making the water tank 2 and humidifying component 3 visible to the user. The user can then directly place the water tank 2 and humidifying component 3 into a sink or dishwasher for cleaning. During assembly, simply place the humidifying component 3 on the water tank 2 and then cover the housing 1 over the water tank 2, improving the ease of disassembly and assembly of the humidifier 100 for cleaning.

[0088] In some embodiments, such as Figure 4 As shown, the water circuit assembly 4 includes a sliding connection assembly 43. The water pump assembly 42 is detachably connected to the bracket 41 via the sliding connection assembly 43.

[0089] For example, the sliding connection assembly may include a groove and a protrusion, one of which is disposed on a bracket, and the other of which is disposed on the bracket. The protrusion is slidable in the groove. When the protrusion slides to the locked position, the water pump assembly and the bracket are locked together. When the protrusion slides to the unlocked position, the water pump assembly and the bracket are detachable.

[0090] For example, the sliding connection assembly may include a track and a clamping element. One of the track and the clamping element may be disposed on the pump assembly, and the other of the guide track and the clamping element may be disposed on the bracket. The clamping element may be configured with retractable jaws that can slide freely within the guide track. When the pump assembly is mounted on the bracket, the jaws automatically clamp under the constraint of the track, thereby securing the pump assembly to the bracket. When it is necessary to disassemble the pump assembly, the jaws can be released from the track, and then the pump assembly can be slid out along the track.

[0091] In some embodiments, such as Figure 4 and Figure 5 As shown, the sliding connection assembly 43 may include a limiting groove 431 and a first limiting member 432. One of the limiting groove 431 and the first limiting member 432 is disposed on the water pump assembly 42, and the other of the limiting groove 431 and the first limiting member 432 is disposed on the bracket 41.

[0092] In some embodiments, such as Figure 4 As shown, the limiting groove 431 can be provided on the bracket 41. The bracket 41 can be a cavity structure, and the limiting groove 431 can penetrate through the side wall of the bracket 41 and communicate with the cavity of the bracket 41.

[0093] In some embodiments, the first limiting member 432 may be disposed on the water pump assembly 42. The first limiting member 432 is capable of sliding within the limiting groove 431 along a first direction. The first direction may be a vertical direction or a horizontal direction. The first limiting member 432 may be disposed on the water pump assembly 42. The first limiting member 432 and the limiting groove 431 may mutually limit each other along a second direction. The second direction may be perpendicular to the first direction or nearly perpendicular to it.

[0094] This application uses the vertical direction as the first direction for illustrative purposes. The first direction can be... Figures 3 to 5 The Y direction in the equation. The second direction can be... Figures 3 to 5 The X direction in the equation.

[0095] In some embodiments, such as Figure 4 As shown, a first limiting part 434 is provided inside the limiting groove 431. The first limiting part 434 can be located at the corner of the limiting groove 431 and occupy part of the space of the limiting groove 431.

[0096] In some embodiments, such as Figure 5As shown, the first limiting member 432 is provided with a slot 435. The opening of the slot 435 faces the first direction and the second direction. When the first limiting member 432 slides along the first direction, the first limiting part 434 can be inserted into the slot 435 in the first direction. Then, the first limiting part 434 is locked in the slot 435 along the second direction. That is, the first limiting part 434 and the slot 435 mutually limit each other along the second direction.

[0097] For example, when the water pump assembly 42 needs to be assembled with the bracket 41, the first limiting member 432 can be inserted into the limiting groove 431. The length of the limiting groove 431 along the first direction can be greater than the length of the first limiting member 432, and the length of the limiting groove 431 along the second direction can match the length of the first limiting member 432. As the first limiting member 432 gradually approaches the end of the limiting groove 431, the first limiting part 434 is inserted into the slot 435, thereby limiting the first limiting member 432 and the limiting groove 431 to each other, and thus limiting the water pump assembly 42 and the bracket 41 to each other along the second direction.

[0098] In some embodiments, such as Figure 4 As shown, the sliding connection assembly 43 may further include a second limiting member 433. The second limiting member 433 may be disposed on the bracket 41. The second limiting member 433 is used to limit the water pump assembly 42 along the first direction.

[0099] Specifically, the second limiting member 433 can be an elastic buckle 451, and can produce elastic deformation.

[0100] In some embodiments, the second limiting member 433 may be configured as a cantilever structure and disposed at the end of the bracket 41.

[0101] When it is necessary to disassemble the water pump assembly 42, force can be applied to the second limiting member 433 to release its limitation on the water pump assembly 42, and then the water pump assembly 42 can be slid to make the first limiting part 434 disengage from the slot 435; when installing the water pump assembly 42, force can be applied to the second limiting member 433 to release its obstruction, the first limiting member 432 can be inserted into the limiting groove 431 and slid until it engages with the first limiting part 434 in the slot 435, and then the second limiting member 433 can be reset to complete the limitation on the water pump assembly 42.

[0102] Thus, the first limiting member 432 and the limiting groove 431 in the sliding connection assembly 43 can mutually limit each other along the second direction, and the second limiting member 433 can mutually limit the water pump assembly 42 along the first direction. When the user disassembles and assembles the water pump assembly 42 and the bracket 41, it is necessary to release the limiting between the second limiting member 433 and the water pump, and the limiting between the first limiting member 432 and the limiting groove 431, respectively. This double-safety design reduces the risk of accidental disassembly of the water pump assembly 42 and achieves a stable connection between the water pump assembly 42 and the bracket 41. In addition, the sliding connection between the water pump assembly 42 and the bracket 41 makes disassembly easier and improves the efficiency of disassembly and assembly.

[0103] In some embodiments, the humidifier 100 may include an electronic control box 6. For example... Figure 3 As shown, the water circuit assembly 4 includes an electrical connection line 44 that connects the electrical control box 6 and the water pump assembly 42.

[0104] When the water pump assembly 42 is mounted on the bracket 41, the electrical connection wire 44 has a reserved slack, that is, the electrical connection wire 44 is loosely connected between the water pump assembly 42 and the electrical control box 6.

[0105] In some embodiments, the sliding connection distance between the pump assembly 42 and the bracket 41 is less than the reserved slack of the electrical connection line 44.

[0106] By setting a slack allowance in the electrical connection wire 44, the electrical connection wire 44 will not be excessively pulled or damaged when the water pump assembly 42 and the bracket 41 slide relative to each other and are disassembled. This reduces the risk of wire breakage or poor contact caused by disassembly or assembly operations and improves the reliability and safety of the water pump assembly 42.

[0107] In some embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, the water pump assembly 42 may include a first housing 422. The aforementioned first limiting member 432 is disposed outside the first housing 422. The first housing 422 has a receiving space 422a, and a water inlet pipe 4231 is disposed inside the first housing 422, the water inlet pipe 4231 being connected to a first water inlet at the bottom end of the first housing 422 in the vertical direction.

[0108] In some embodiments, such as Figure 6 As shown, the end of the first housing 422 opposite to the first water inlet may also be provided with a detachable cover 45. When it is necessary to clean the scale inside the first housing 422, the cover 45 can be removed and the inside of the first housing 422 can be cleaned with a washing tool (brush, etc.).

[0109] In some embodiments, such as Figure 5As shown, the water pump assembly 42 may include a drive unit 423. The drive unit 423 is disposed within the receiving space 422a of the first housing 422. The drive unit 423 may be a submersible motor, so that the water pump assembly 42 can be placed in the water storage chamber 20 of the water tank 2 for a long time and maintain effective operation.

[0110] In some embodiments, such as Figure 5 As shown, the water pump assembly 42 may further include an impeller 424. The impeller 424 is connected to the drive member 423 and disposed outside the first housing 422. The drive member 423 drives the impeller 424 to rotate, converting mechanical energy into the kinetic and pressure energy of the water, thereby realizing the delivery and pressurization of the water flow in the water tank 2 and pumping it out of the water tank 2.

[0111] It is understandable that the impeller 424 directly disturbs the water flow. Therefore, placing the impeller 424 on the outside of the first housing 422 makes it easier for the user to clean the scale adhering to the impeller 424.

[0112] In some embodiments, such as Figure 5 , Figure 7 and Figure 8 As shown, the water pump assembly 42 may include a water guide valve 425. A water guide cavity 4251 is formed within the water guide valve 425. The water guide cavity 4251 is connected to the water outlet cavity and the water inlet pipe 4231 of the water tank 2. An impeller 424 is housed within the water guide cavity 4251.

[0113] The water flow area of ​​the water guide cavity 4251 gradually decreases towards the first water inlet. The impeller 424 disturbs the water flow during rotation. The water flow disturbed by the impeller 424 is pressurized as it flows towards the first water inlet, and can then be pumped into the water inlet pipe 4231.

[0114] In some embodiments, such as Figure 7 and Figure 8 As shown, the water guide valve 425 includes a third water inlet 4253, which is connected to the water guide cavity 4251 so that water can flow into the water guide cavity 4251.

[0115] Thus, the impeller 424 rotates within the water guide valve 425, achieving the function of conveying and pressurizing water. The water guide chamber 4251 of the water guide valve 425 further optimizes the water flow path, improving the overall efficiency of the water pump assembly 42. Furthermore, placing the impeller 424 outside the first housing 422 facilitates user cleaning of scale on the impeller 424, thereby maintaining the working performance of the water pump assembly 42.

[0116] In some embodiments, such as Figure 7 As shown, the water guide valve 425 is detachably connected to the first housing 422.

[0117] The water guide valve 425 is detachably connected to the first housing 422, facilitating thorough cleaning of the interior of the water guide cavity 4251 and exposing the impeller 424 for cleaning. Especially in areas with hard water, users can more easily remove the water guide valve 425 from the first housing 422 to clean the scale deposited in the impeller 424 and the water guide cavity 4251, ensuring efficient operation of the water pump assembly 42.

[0118] In some embodiments, such as Figure 6 and Figure 7 As shown, the water pump assembly 42 may also include a cover 426. The cover 426 covers the water valve 425 and is detachably connected to the first housing 422.

[0119] The protective cover 426 is provided with a second water inlet 4262 at the position of the third water inlet 4253 of the water guide valve 425. The second water inlet 4262 is connected to the third water inlet 4253, so that the water in the water storage chamber 20 of the water tank 2 flows into the third water inlet 4253 through the second water inlet 4262, and enters the first water inlet after being pressurized by the impeller 424 and the water guide chamber 4251, and then flows into the water inlet pipe 4231, so that the water in the water tank 2 is pumped out of the water storage chamber 20.

[0120] The protective cover 426 is removable relative to the first housing 422. When it is necessary to clean the water pump assembly 42, the protective cover 426 can be removed from the first housing 422 first, then the water guide valve 425 can be removed, and then the scale attached to the water guide valve 425, impeller 424 and protective cover 426 can be thoroughly cleaned, thereby achieving a thorough cleaning of the water pump assembly 42.

[0121] In some embodiments, such as Figure 5 As shown, the first housing 422 is provided with a sliding groove 4223. The sliding groove 4223 can be provided at the bottom end of the first housing 422. The number of sliding grooves 4223 can be at least two, and they are arranged at intervals along the circumference of the impeller 424.

[0122] In some embodiments, the water valve 425 is provided with a protrusion 4252. The protrusion 4252 can extend into the slide groove 4223, and when the water valve 425 is rotated, the protrusion 4252 can slide within the slide groove 4223. The protrusion 4252 can extend vertically. The number of protrusions 4252 can be the same as the number of slide grooves 4223.

[0123] In some embodiments, such as Figure 7 As shown, the protective cover 426 includes a second limiting part 4261. The second limiting part 4261 can extend in a vertical direction and can also extend into the slide groove 4223.

[0124] When the water valve 425 rotates relative to the first housing 422 and reaches the locked position, the protrusion 4252 abuts against the end of the slide groove 4223. Subsequently, the second limiting part 4261 of the cover 426 is inserted into the slide groove 4223. The second limiting part 4261 fills the empty space in the slide groove 4223, thereby limiting the protrusion 4252. The protrusion 4252 stops sliding and remains in this position, and the water valve 425 is securely fixed to the locked position. That is, the assembly process of the cover 426 and the first housing 422 can be completed simultaneously with the assembly process of the water valve 425 and the first housing 422, further improving the efficiency of cleaning the water pump assembly 42.

[0125] In some embodiments, the second limiting portion 4261 and the protrusion 4252 form an interference fit. That is, when the second limiting portion 4261 is inserted into the slide groove 4223, friction is generated between the second limiting portion 4261 and the protrusion 4252, thereby improving the connection stability between the cover 426, the first housing 422 and the water valve 425.

[0126] Thus, the process of assembling the protective cover 426 into the first housing 422 will be more convenient. Only a simple plug-and-play operation is needed to install and remove the protective cover 426 and the water guide valve 425 from the first housing 422, reducing the burden of disassembling and assembling the cleaning pump assembly 42.

[0127] In some embodiments, such as Figure 5 As shown, a receiving space 422a is provided inside the first housing 422. This receiving space 422a is used to hold cleaning substances. The cleaning substances can be cleaning particles or descaling particles, etc. The cleaning substances can be used to remove scale from the water tank 2.

[0128] In some embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, the first housing 422 is provided with a first opening 4221 and a second opening 4222 communicating with the receiving space 422a. The first opening 4221 and the second opening 4222 can be offset from each other. For example, the second opening 4222 can be located away from the bottom wall of the water tank 2 relative to the first opening 4221, so as to be offset from each other in the vertical direction.

[0129] By vertically offsetting the first housing 422 and the second opening 4222, the water flow can more easily form a fluid circulation within the first housing 422, allowing the cleaning substance to be dispersed more quickly and evenly inside the water tank 2, thereby improving the cleaning efficiency of the cleaning substance.

[0130] In some embodiments, such as Figure 6As shown, a resilient buckle 451 is provided on the cover 45. The cover 45 is detachably engaged with the second port 4222 via the resilient buckle 451. That is, the second port 4222 is not only used to allow water to flow through so that the cleaning substance can be more fully mixed with the water flow, but can also be reused as a component for assembly with the cover 45, thus simplifying the structure of the water pump assembly 42.

[0131] In some embodiments, such as Figure 4 and Figure 6 As shown, the cover 45 is also provided with a connection port 452. The connection port 452 is located on the side of the cover 45 away from the drive unit 423, and the connection port 452 is connected to the water inlet pipe 4231.

[0132] In some embodiments, such as Figure 2 As shown, the water circuit assembly 4 may include a heating pipe 411. The heating pipe 411 is disposed inside the bracket 41 and connected to the water pump assembly 42. The heating pipe 411 is located outside the water tank 2 and is used to heat the water pumped by the water pump and supply water to the humidification assembly 3.

[0133] Unlike related technologies where the humidifier 100 heats the entire water in the water tank 2, which consumes a large amount of energy, this embodiment places the heating element 411 within the water circuit assembly 4 and positions it outside the water tank 2. This allows the heating element 411 to heat only the water drawn from the water tank 2 by the water pump and flowing within it. Compared to related technologies, the heating solution provided in this embodiment significantly reduces the amount of water heated. This reduces energy consumption and allows for a faster heating process, quickly providing the humidification assembly 3 with a suitable temperature of humidifying water, meeting users' immediate humidification needs, and improving the humidifier 100's response speed and user experience.

[0134] In addition, the heating element 411 is located outside the water tank 2, and the heating element 411 will not be immersed in the water tank 2 for a long time. The separation of the heating element 411 from the water tank 2 further optimizes the water and electricity separation design and improves the safety and reliability of the humidifier 100.

[0135] Thus, the humidifier 100 provided in this embodiment utilizes the water circuit assembly 4 as the working component for heating the water in the water tank 2. The addition of a heating element 411 to the water circuit assembly 4 enables heating of a small volume of water (water pumped by the pump), significantly improving the response speed and energy efficiency of the humidifier 100. Furthermore, the heating element 411 is located outside the water tank 2, reducing the safety risks that may arise from prolonged immersion of the heating element 411 in water, thereby improving the safety and reliability of the humidifier 100. Simultaneously, the water circuit assembly 4 serves both to supply water to the humidification component 3 and to heat the water, optimizing the structure of the humidifier 100 and allowing for further compactness and miniaturization.

[0136] In some embodiments, the heating element 411 is disposed inside the bracket 41. The water pump assembly 42 is detachably connected to the heating element 411 by being detachably connected to the bracket 41, so that the water inlet of the heating element 411 is visible from the outside.

[0137] Because scale easily forms on the heating element 411 during the heating process, long-term use can lead to scale buildup that affects heating efficiency and may even damage the heating element 411 or cause blockages in the water circuit. By making the heating element 411 detachable from the water pump assembly 42, the port of the heating element 411 can be exposed to the user. The user can use a cleaning brush to reach inside the heating element 411 to clean the scale and restore its normal operating performance.

[0138] In some embodiments, the connection port 452 can be detachably plugged into the heating tube 411.

[0139] When the water pump assembly 42 is assembled onto the bracket 41, the connection port 452 of the cover 45 of the first housing 422 is directly inserted into the heating tube 411, which further improves the assembly efficiency between the water pump assembly 42 and the heating tube 411.

[0140] In some embodiments, such as Figure 3 , Figure 4 and Figure 9 As shown, the water circuit assembly 4 may include a water outlet pipe 46. The water outlet pipe 46 is located on the side of the partition 13 opposite to the humidification assembly 3. The water outlet pipe 46 is connected to the heating pipe 411, thereby guiding the water heated by the heating pipe 411 to the mesh 32 of the humidification assembly 3.

[0141] In some embodiments, such as Figure 9 As shown, a water outlet 132 is provided on the partition 13. The end of the water outlet pipe 46 is connected to the water outlet 132. Along the height direction, the water outlet 132 corresponds to the humidification component 3 so that the water flowing from the water circuit component 4 wets the mesh cloth 32.

[0142] In some embodiments, such as Figure 10As shown, the bracket 41 can be installed on top of the water tank 2 and used as a water receiving tray. The bracket 41 is detachably installed at the open end of the water tank 2. Along the height direction of the humidifier 100, the humidification component 3 is detachably installed on one side of the bracket 41, and the water pump component 42 is detachably installed on the other side of the bracket 41 and can be placed inside the water tank 2. In this way, the bracket 41 not only provides structural support for the water pump component 42, but also provides structural support for the humidification component 3, thus simplifying the number of structural components inside the humidifier 100.

[0143] The bracket 41 can be constructed as a disc-shaped structure. The bracket 41 can be attached to the open end of the water tank 2, allowing for easy removal from the water tank 2. The humidifying assembly 3 can also be attached to the bracket 41. When cleaning the water pump assembly 42 is required, the bracket 41 and the humidifying assembly 3 can be easily separated, the bracket 41 can be removed from the water tank 2, and the water pump assembly 42 can be detached from the bracket 41, thus achieving convenient disassembly of the water pump assembly 42.

[0144] In some embodiments, such as Figure 11 As shown, the humidification assembly 3 includes a water guide pipe 34. The water guide pipe 34 is connected to the water pump assembly 42. The top of the humidification assembly 3 may include a water distribution plate 33. The water outlet end of the water guide pipe 34 may be located inside the water distribution plate 33, so that the water drawn by the water pump assembly 42 flows evenly into the mesh 32 of the humidification assembly 3.

[0145] In some embodiments, such as Figure 12 As shown, a drain section 413 communicating with the water tank 2 is provided on the bracket 41. The drain section 413 can be located in the central area of ​​the bracket 41. The humidifying component 3 has water-holding capacity. When the water in the humidifying component 3 reaches its upper limit, the excess water will flow back to the water tank 2 through the drain section 413, thereby forming a water circulation cycle of water tank 2-water pump assembly 42-humidifying component 3-water tank 2.

[0146] In some embodiments, such as Figure 13 As shown, the drain section 413 can be configured as a recessed cavity 4131 that is recessed into the water tank 2. The cavity 4131 can store a portion of the water, reducing the accumulation of water on the surface of the support 41, so as to prevent water from overflowing from the support 41 into the humidifier 100.

[0147] In some embodiments, a cleaning substance may be contained within the cavity 4131. The cleaning substance is detachably disposed within the cavity 4131. The cleaning substance may be a water softener, cleaning particles, etc. Before the water overflowing from the humidification component 3 flows back to the water tank 2, it passes through the cleaning substance in the drain section 413, which can reduce the probability of scale formation in the water tank 2 and make the water in the water tank 2 have a higher degree of cleanliness.

[0148] In some embodiments, such as Figure 12 and Figure 13 As shown, the water pump assembly 42 includes a flow guide 421. The flow guide 421 is detachably connected to the bracket 41 and is located on the side of the bracket 41 opposite to the humidification assembly 3.

[0149] In some embodiments, the bottom of the flow deflector 421 is open to allow fluid communication with the water tank 2.

[0150] In some embodiments, such as Figure 13 As shown, the drainage section 413 has a notch 414. The flow guide 421 may be partially located within the notch 414, and there is a drainage gap 415 between the flow guide 421 and the inner wall of the notch 414 for draining the water flow collected in the drainage section 413.

[0151] It should be noted that the drainage gap 415 between the guide shield 421 and the notch 414 is designed to allow the water collected in the drainage section 413 to flow smoothly along the outer wall of the guide shield 421. It is understandable that by properly controlling the size of the drainage gap 415, the flow rate and volume of the water can be reduced to a certain extent, preventing excessive water flow from directly impacting the surface of the water tank 2 or the guide shield 421 and generating noise.

[0152] Meanwhile, the recess 4131 of the drain section 413 cooperates with the drain gap 415 to form a staged drainage. When the humidifying component 3 is saturated with water, the excess water is temporarily stored in the recess 4131 of the drain section 413, and then flows smoothly back to the water tank 2 through the drain gap 415 along the guide cover 421. This not only prevents water from overflowing from the bracket 41 to the humidifier 100, but also reduces the noise that may be generated during the return flow process.

[0153] In some embodiments, such as Figure 13 As shown, the flow guide shroud 421 includes a first flow guide surface 4211 inclined relative to the axis of the humidifier 100. This allows water flowing from the drain gap 415 to smoothly flow into the water tank 2 along the inclined surface of the first flow guide surface 4211, further reducing noise generated when water flows into the water tank 2. The inclined first flow guide surface 4211 also optimizes the water flow direction, allowing the water to flow naturally under gravity.

[0154] In some embodiments, such as Figure 13 As shown, the flow guide 421 expands in the direction toward the bottom wall of the water tank 2.

[0155] The flow guide shroud 421 is constructed with a flared structure, meaning that the internal space of the flow guide shroud 421 can gradually increase towards the bottom wall of the water tank 2. In this way, on the one hand, the first flow guide surface 4211 on the outer surface of the flow guide shroud 421 can be inclined, and on the other hand, the flow guide shroud 421 can have a larger accommodating space 422a to accommodate the pump body 427 of the water pump assembly 42.

[0156] In some embodiments, such as Figure 13 and Figure 14 As shown, the water pump assembly 42 also includes a pump body 427. The pump body 427 is used for pumping water, and the pump body 427 can be a submersible water pump.

[0157] The pump body 427 is detachably mounted on the flow guide 421. In this way, when it is necessary to disassemble the water pump assembly 42, the pump body 427 inside the flow guide 421 can be removed by holding the flow guide 421, and then the pump body 427 can be separated from the flow guide 421, thereby facilitating the cleaning of the pump body 427.

[0158] In some embodiments, the pump body 427 includes a connecting pipe 4271 communicating with the water guide pipe 34. The connecting pipe 4271 is detachably connected to the water guide pipe 34, thereby making the pump body 427 detachable from the water guide pipe 34.

[0159] Since the pump body 427 is used to draw water from the water tank 2, it may need to be immersed in the water tank 2 for a long time. Scale is easily attached to the pump body 427. The pump body 427 and the water pipe 34 are detachable, so the pump body 427 can be cleaned more conveniently.

[0160] In some embodiments, the connecting pipe 4271 and the water guide pipe 34 are coaxially arranged. The coaxial connecting pipe 4271 and the water guide pipe 34 keep the flow path straight, reduce turbulence or pressure loss that may be caused by the bends of the connecting pipe 4271 and the water guide pipe 34, improve the water delivery efficiency of the pump body 427, reduce the noise during the water flow process, and also reduce the operating power of the pump body 427.

[0161] In some embodiments, the connecting pipe 4271 is detachably connected to the flow guide 421. This detachable connection not only makes it easier to clean the pump body 427 separately, but also allows for cleaning of the inner wall of the flow guide 421, keeping the flow guide 421 clean.

[0162] In some embodiments, such as Figure 13 and Figure 14 As shown, the water pump assembly 42 also includes a water level detection element 428. The water level detection element 428 can be a water level sensor to detect the water level in the water tank 2. If the water level in the water tank 2 is insufficient, the control device of the humidifier 100 can remind the user to add water to the water tank 2 based on the detection value of the water level detection element 428.

[0163] In some embodiments, such as Figure 13 As shown, the bracket 41 has a recessed second guide surface 416 facing the interior of the water tank 2. The second guide surface 416 faces the humidification assembly 3. The second guide surface 416 is disposed at least partially around the drain section 413 and connected to the outer periphery of the drain section 413.

[0164] The second guide surface 416 can cause the water left on the bracket 41 by the humidification component 3 to converge to the drain 413 by gravity, thereby reducing the risk of water overflowing from the bracket 41 into the humidifier 100.

[0165] In some embodiments, such as Figure 13 and Figure 14 As shown, the bracket 41 is also provided with an overflow port 417. The overflow port 417 can extend to the second guide surface 416. As mentioned above, water overflowing from the humidification component 3 flows into the water tank 2 through the bracket 41. If drainage is not smooth, water may accumulate on the bracket 41 and may overflow the humidifier 100. Providing an overflow port 417 on the bracket 41 can reduce the risk of water overflow.

[0166] In some embodiments, such as Figure 12 and Figure 13 As shown, the bracket 41 is also provided with an anti-overflow rib 418, which is connected to the periphery of the overflow port 417 and extends in a direction away from the water pump assembly 42. It is understood that the volume of water flowing directly into the water tank 2 from the overflow port 417 may be greater than the volume of water flowing into the water tank 2 from the drain gap 415 and through the first guide surface 4211. The anti-overflow rib 418 can stop the overflow of water from the humidification assembly 3, allowing the water on the bracket 41 to pass through the drain section 413 and the cleaning agent, and then flow into the water tank 2 through the drain gap 415 between the bracket 411 and the guide cover 421, rather than flowing directly into the water tank 2 from the overflow port 417, thereby reducing water flow noise and improving the cleanliness of the water in the water tank 2.

[0167] In some embodiments, such as Figure 10 and Figure 12 As shown, multiple overflow ports 417 are spaced apart around the outer periphery of the drain section 413. The arrangement of multiple overflow ports 417 can efficiently overflow water to the water tank 2 when the drain section 413 cannot drain water quickly, so as to prevent water from overflowing from the bracket 41 into the humidifier 100.

[0168] In some embodiments, the anti-overflow rib 418 includes a third limiting portion 4181 that cooperates with the limiting portion of the humidification assembly 3. The overflow port 417 may be located within the inner cavity of the humidification assembly 3 in the horizontal direction. The humidification assembly 3 may be constructed as a hollow cylindrical structure to allow airflow. The inner cavity of the humidification assembly 3 may be a hollow cavity. Thus, the anti-overflow rib 418 is also provided within the inner cavity of the humidification assembly 3.

[0169] In some embodiments, there are multiple anti-overflow ribs 418 and overflow ports 417. A third limiting part 4181 may be provided on the anti-overflow ribs 418, so that multiple anti-overflow ribs 418 can stably limit the humidification component 3 on the bracket 41, preventing the humidification component 3 from shifting under the influence of airflow.

[0170] Thus, the anti-overflow rib 418 can be used as an anti-overflow component and as a limiting component for the humidification component 3, making the structure of the bracket 41 more compact and optimizing the spatial layout of the bracket 41.

[0171] In some embodiments, such as Figure 10 and Figure 11 As shown, the water circuit assembly 4 may further include a power supply bracket 48, which is disposed around the humidification assembly 3. One end of the power supply bracket 48 can be attached to the water distribution tray 33 of the humidification assembly 3, and the other end of the power supply bracket 48 is connected to the water pump assembly 42. The power supply bracket 48 is detachably connected to the water pump assembly 42 and is also detachably connected to the humidification assembly 3.
