At least part of the air outlet and the mesh fabric are positioned on the same arc, which lies within the space of the airflow channel. The airflow driven by the fan passes through the wetted mesh fabric along the arc-shaped airflow path. This arc layout optimizes the space utilization of the airflow channel, reduces energy loss caused by airflow vortices, and thus improves water evaporation efficiency and enhances humidification capacity. It also reduces the fan's operating resistance, reducing energy consumption and noise. This achieves a dual optimization of efficient humidification and energy saving / noise reduction.

[0021] In one implementation, the projection of the air outlet at least partially overlaps with the projection of the mesh fabric in the height direction of the housing.

[0041] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0042] In the description of the embodiments of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0043] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0044] In the embodiments of this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0045] A humidifier based on related technology includes a housing, a water tank, a mesh fabric, a water circuit assembly, and a fan. The water tank is installed in the housing, and the side wall of the housing has an air inlet and an air outlet, with the air outlet located above the air inlet. The mesh fabric is disposed on the inner wall of the housing and positioned opposite the air outlet. The water circuit assembly draws water from the water tank to wet the mesh fabric. The fan generates an airflow from the air inlet to the air outlet. The airflow passes through the mesh fabric, causing the moisture on the mesh fabric to evaporate and be blown out with the airflow to humidify the air.

[0046] In one type of humidifier, the water circuit assembly is located on the side wall of the casing and on the outer periphery of the mesh fabric. Because the side wall of the casing with the water circuit assembly cannot have an air inlet for air intake, while the side wall without the water circuit assembly can have an air inlet, the air intake structure is uneven, resulting in uneven airflow around the casing, significant differences in evaporation rate at different locations on the mesh fabric, poor humidification effect, and a large overall footprint. Furthermore, the water pump in the water circuit assembly is close to the outer periphery of the water tank, causing the noise generated by the pump to propagate directly outwards, resulting in significant noise and a poor user experience.

[0047] Please see Figures 1 to 4 , Figure 9This application provides a humidifier 100, including a housing 10, a water tank 20, a mesh fabric 30, a water channel assembly 40, and a fan 50. The housing 10 has an air inlet 11, an air outlet 12, and an airflow channel 10c. The water tank 20 is installed in the housing 10. The mesh fabric 30 is located within the airflow channel 10c. The water channel assembly 40 is used to transfer water 1 from the water tank 20 to the mesh fabric 30. The fan 50 is disposed in the housing 10 and is used to generate an airflow from the air inlet 11 to the air outlet 12. The air inlet 11, the air outlet 12, and the airflow channel 10c are connected. In the height direction Z of the housing 10, the projection of the air outlet 12 and the projection of the mesh fabric 30 at least partially overlap.

[0048] The water tank 20 is installed on the housing 10. The water tank 20 can be installed inside the housing 10 or outside the housing 10. The water tank 20 can be located at the bottom, top or side wall of the housing 10.

[0049] The beneficial effects of the humidifier 100 provided in this embodiment are as follows: the water circuit assembly 40 can transfer water 1 in the water tank 20 to the mesh fabric 30, thus wetting the mesh fabric 30. The airflow generated by the fan 50 enters the airflow channel 10c through the air inlet 11 and is discharged at the air outlet 12. In the height direction Z of the housing 10, the projection of the air outlet 12 and the projection of the mesh fabric 30 at least partially overlap. The airflow blows over the wetted mesh fabric 30, the moisture in the mesh fabric 30 vaporizes, and the airflow carrying moisture flows along the airflow channel 10c and is discharged at the air outlet 12, achieving stable and low-resistance airflow, reducing the turning of the airflow in different directions, and improving the overall humidification efficiency.

[0050] In some embodiments, please refer to Figures 1 to 3 The casing 10 can be cylindrical, cuboid, cube, or similar shapes. The water tank 20 and casing 10 are designed to fit together, and the outer wall of the water tank 20 can be positioned close to the inner wall of the casing 10. Given the limited volume of the casing 10, the water tank 20 is designed to have a larger volume to hold more water.

[0051] For example, the housing 10 is generally cylindrical, and the water tank 20 is cylindrical. The water tank 20 is installed at the bottom of the housing 10, and the bottom of the housing 10 is fitted over the water tank 20, giving the humidifier 100 a good overall appearance.

[0052] In some embodiments, please refer to Figure 4 At least a portion of the air outlet 12 and the mesh fabric 30 are located on the same arc L1, which lies within the space of the airflow channel 10c. The space of the airflow channel 10c may include at least the space enclosed by the air inlet 11, the mesh fabric 30, the space of the fan 50, and the air outlet 12. The airflow channel 10c may be the air-circulating space between the air inlet 11 and the air outlet 12 of the humidifier 100.

[0053] Driven by fan 50, the airflow travels along an arc-shaped airflow path through the wetted mesh fabric 30. This arc-shaped layout optimizes the space utilization of the airflow channel, reduces energy loss caused by airflow vortices, and thus improves moisture evaporation efficiency and enhances humidification capacity. It also reduces the operating resistance of fan 50, decreasing energy consumption and noise. This achieves a dual optimization of high-efficiency humidification and energy saving / noise reduction.

[0054] In some embodiments, at least a portion of the air outlet 12 and the mesh 30 are located on the same arc L1, which lies within the space of the airflow channel 10c. The airflow channel 10c can be the space between the air inlet 11 and the air outlet 12 of the humidifier 100 where air can circulate. This structural arrangement and spatial layout can also be applied to humidifiers with various structural forms, such as when the water circuit assembly of the humidifier is not located in the central area of ​​the casing, or when the humidifier includes a casing, a water tank, a mesh, and a fan, and the water in the water tank can flow onto the mesh by gravity, or the water tank can be located on the top or side wall of the humidifier, not limited to the structure shown in the figures of this application.

[0055] Please see Figure 4 Along the height Z direction of the casing 10, the ratio of the projected area of ​​the top air passage zone S1 of the mesh fabric 30 to the projected area of ​​the bottom air passage zone S2 of the fan 50 is greater than or equal to 2. The top air passage zone S1 of the mesh fabric 30 is the top opening position of the annular mesh fabric 30. The bottom air passage zone S2 of the fan 50 refers to the bottom opening position of the fan 50.

[0056] By limiting the ratio of the projected area of ​​the top air passage zone S1 of the mesh fabric 30 to the projected area of ​​the bottom air passage zone S2 of the fan 50, the external airflow can pass evenly through different parts of the mesh fabric 30, improving the turbulence problem caused by dense airflow distribution. This allows the airflow to smoothly enter the bottom air passage S2 of the fan 50 from the top air passage zone S1 of the mesh fabric 30, reducing the stagnation of airflow above the mesh fabric 30.

[0057] In some embodiments, in the height direction Z of the humidifier housing 10, the ratio of the projected area of ​​the top air passage zone S1 of the mesh 30 to the projected area of ​​the bottom air passage zone S2 of the fan 50 is greater than or equal to 2. This structural arrangement and spatial layout can also be applied to humidifiers with various structural forms. For example, a humidifier may include a housing, a water tank, a mesh, and a fan. The vertical spatial relationship between the mesh and the fan may be that the mesh is on top and the fan is at the bottom, or the fan is located within the space enclosed by the mesh.

[0058] Please see Figure 3 , Figure 4 In the top-to-bottom direction, the fan 50, the mesh 30, and the water tank 20 are arranged sequentially and without overlap. That is, the fan 50 and the mesh 30 do not overlap, the mesh 30 and the water tank 20 do not overlap, and there can be a certain gap between adjacent ones.

[0059] For both the fan 50 and the mesh 30, the ratio of their height difference to the height of either one is less than or equal to 20%. For both the mesh 30 and the water tank 20, the ratio of their height difference to the height of either one is less than or equal to 20%. The height difference refers to the distance in the vertical direction between the bottom of the upper structure and the top of the lower structure.

[0060] By limiting the ratio of the height difference between the fan 50 and the mesh 30 to the height of either of them, the airflow can be stabilized and pass through the mesh 30 with low resistance, reducing pressure loss caused by the height difference and improving humidification efficiency. By limiting the ratios of the height difference between the fan 50 and the mesh 30 to the height of either of them, and the ratios of the height difference between the mesh 30 and the water tank 20 to the height of either of them, the humidifier 100 maintains a stable center of gravity, mitigating vibration or swaying problems caused by a shift in the center of gravity.

[0061] In some embodiments, the fan 50, mesh fabric 30, and water tank 20 are arranged sequentially and non-overlappingly in a top-to-bottom direction. That is, the fan 50 and mesh fabric 30 do not overlap, and the mesh fabric 30 and water tank 20 do not overlap, with a certain gap between adjacent ones. The ratio of the height difference between the fan 50 and mesh fabric 30 to the height of either one is less than or equal to 20%. The ratio of the height difference between the mesh fabric 30 and water tank 20 to the height of either one is less than or equal to 20%. This structural arrangement and spatial layout can also be applied to humidifiers with various structural forms. For example, the air inlet and outlet can be adjusted, such as both the air inlet and outlet being located on the side wall, or the air inlet being located at the bottom or the air outlet being located at the top, etc., and is not limited to the structure shown in the figures of this application.

[0062] Please see Figure 4 The outer diameter D1 of the impeller of the fan 50 is smaller than the outer diameter D2 of the mesh fabric 30. When the fan 50 is working, a negative pressure is generated at the bottom of the fan 50. The external airflow passes from the outside to the inside through the annular wetted mesh fabric 30, and the airflow carries away the moisture from the mesh fabric 30 into the inner cavity of the mesh fabric 30, and then into the fan 50. The outer diameter D2 of the mesh fabric 30 is set to be relatively large, which helps to reduce the negative pressure, stabilize the airflow, and achieve a stable humidification effect.

[0063] In some embodiments, the outer diameter D1 of the impeller of the fan 50 is smaller than the outer diameter D2 of the mesh 30. This structural arrangement and spatial layout can also be applied to humidifiers with various structural forms. For example, the air inlet and outlet can be adjusted, such as both the air inlet and outlet being located on the side wall, or the air inlet being located at the bottom or the air outlet being located at the top. For example, water in the water tank can flow onto the mesh by gravity, or the water tank can be located at the top or side wall of the humidifier, etc., and is not limited to the structure shown in the figures of this application.

[0064] Please see Figure 4 The outer diameter D2 of the mesh fabric 30 is smaller than the outer diameter D3 of the water tank 20. The larger outer diameter D3 of the water tank 20 lowers the overall center of gravity, improving stability and mitigating the risk of tipping or swaying during operation and movement, thus enhancing safety. This also contributes to the overall structural stability and increased durability over long-term use.

[0065] In some embodiments, the outer diameter D2 of the mesh 30 is smaller than the outer diameter D3 of the water tank 20. This structural arrangement and spatial layout can also be applied to humidifiers with various structural forms. For example, the air inlet and outlet can be adjusted, such as both the air inlet and outlet being located on the side wall, or the air inlet being located at the bottom or the air outlet being located at the top. The fan can also be located in the middle of the mesh enclosure, etc., and is not limited to the structure shown in the figures of this application.

[0066] In some embodiments, see Figures 1 to 4 The water channel assembly 40 is located in the central area 10a of the housing 10. Viewed from above, the central area 10a and the outer perimeter 10b of the housing 10 are relative. The water channel assembly 40 is generally distributed in the central area 10a of the housing 10, which may be at or near the center of the housing 10.

[0067] Compared to related humidifiers that place the water circuit assembly on the side wall of the casing, the humidifier 100 in this embodiment places the water circuit assembly 40 in the central area 10a of the casing 10. This reduces the overall size of the unit, makes the overall structure more balanced and stable, less prone to tilting or tipping over, and does not affect the humidification effect. When the user lifts the casing 10 to separate it from the water tank 20, the water circuit assembly 40 follows the casing 10 and separates from the water tank 20. Because the water circuit assembly 40 is located in the central area 10a of the casing 10, the casing 10 has a larger detachable angle, and the water circuit assembly 40 is less likely to scratch the inner wall of the water tank 20, improving its long-term durability.

[0068] In some embodiments, please refer to Figure 3 , Figure 4 Below the fan 50 is an air inlet grille 13, which has multiple air guide ribs 131 that are distributed outward from a predetermined center. Under the guidance of the multiple air guide ribs 131, the airflow within the mesh 30 can enter the fan 50 evenly and stably.

[0069] The housing 46 of the water channel assembly 40 is connected to the inner end of the air guide rib 131 of the air inlet grille 13, and the outer end of the air guide rib 131 is connected to the housing 10. The air guide rib 131 can extend along an arc or diagonal line to facilitate the airflow in the inner cavity of the mesh 30 to be guided into the air inlet grille 13.

[0070] In some embodiments, please refer to Figure 3 , Figure 4 The housing 10 has an air intake grille 13 inside, and the water channel assembly 40 is installed in the central area of ​​the air intake grille 13. The air intake grille 13 can be assembled inside the housing 10, or the housing 10 and the air intake grille 13 can be integrally formed.

[0071] The air inlet grille 13 facilitates the positioning and assembly of the water channel assembly 40, ensuring that the water channel assembly 40 is located in the central area 10a of the casing 10 without affecting the airflow between the mesh fabric 30 and the outside. When the fan 50 is operating, the airflow around the casing 10 passes through the annular mesh fabric 30 from the outside in, resulting in a relatively uniform airflow around the casing 10 and minimal evaporation differences at different locations on the mesh fabric 30. The air inlet grille 13 can evenly distribute and guide the airflow containing moisture within the inner cavity of the mesh fabric 30, which is then discharged outside the casing 10 after passing through the fan 50.

[0072] The fan 50 can be a centrifugal fan. Without the water channel assembly 40, a negative pressure zone will be generated at the bottom of the fan 50. Because the water channel assembly 40 is located in the center of the air inlet grille 13, airflow cannot pass through the air inlet grille 13 from the water channel assembly 40. A negative pressure zone is formed near the air inlet grille 13, and the airflow entering the inner cavity of the mesh fabric 30 will be attracted by the air inlet grille 13, then pass through the fan 50 and be discharged from the air outlet 12.

[0073] In some embodiments, please refer to Figure 3 , Figure 4 The inner cavity of the fan 50 and the inner cavity of the mesh 30 are connected by an air inlet grille 13; the air inlet grille 13 extends into the inner cavity of the mesh 30. The airflow before and after the air inlet grille 13 can flow stably, which can reduce airflow backflow and interference, and reduce the impact of turbulence.

[0074] In some embodiments, please refer to Figure 3 , Figure 4 The fan 50 and the water circuit assembly 40 are located on the same axis L2. This stabilizes the center of gravity of the humidifier 100, improving the problem of tipping over or swaying due to instability during operation and movement, and enhancing safety. It also makes the humidifier 100 compact in structure and occupies less space.

[0075] In some embodiments, please refer to Figures 3 to 5 A bracket 60 is provided at the top opening 22 of the water tank 20, and a sealing element 70 is provided between the bracket 60 and the water tank 20. The sealing element 70 achieves a waterproof seal between the bracket 60 and the water tank 20. Figure 6 When the humidifier 100 is placed at a certain angle (e.g., 10° to 20°), such as when the user's desktop is not horizontal, the water 1 at the high water level in the water tank 20 can be blocked by the seal 70 and will not easily overflow through the gap between the bracket 60 and the water tank 20.

[0076] In some embodiments, please refer to Figure 3 The bracket 60 and the seal 70 are annular, with the seal 70 fitted over the bracket 60. The annulus can be circular, elliptical, rounded rectangle, rectangular, square, etc., and can be a discontinuous open ring or a continuous closed ring.

[0077] An annular sealing element 70 is installed on the outer sleeve of the annular bracket 60. The sealing element 70 is placed between the bracket 60 and the water tank 20 to achieve a reliable seal between the bracket 60 and the water tank 20, thereby reducing the overflow of water from the high water level in the water tank 20 when the humidifier 100 is placed at a certain angle.

[0078] In some embodiments, please refer to Figure 3 The sealing element 70 can be made of rubber or nylon to achieve a good seal between the bracket 60 and the water tank 20. The rubber element can be made of materials such as nitrile rubber, fluororubber, and silicone rubber.

[0079] In some embodiments, please refer to Figure 5 The bracket 60 has an outward flange 61 along the height direction Z of the housing 10. The seal 70 is sandwiched between the end face 23 of the water tank 20 at the top opening 22 and the outward flange 61. When assembling the bracket 60 and the seal 70 to the top opening 22 of the water tank 20, the outward flange 61 of the bracket 60 and the end face 23 of the water tank 20 together clamp the seal 70, so that the bracket 60 and the seal 70 are limited and installed at the top opening 22, resulting in high assembly efficiency.

[0080] In some embodiments, please refer to Figure 5 In the height direction Z of the casing 10, the position of the outward flange 61 is lower than the position of the air inlet 11. Combined with... Figure 3 The airflow generated by the fan 50 enters the airflow channel 10c through the air inlet 11 and is discharged through the air outlet 12. The outward flange 61 is lower than the air inlet 11, so that the airflow can be fully blown onto the wetted mesh 30, so that the moisture in the mesh 30 is vaporized and flows with the airflow.

[0081] In some embodiments, please refer to Figure 5 The bracket 60 is located on the inner circumference of the top opening 22 of the water tank 20. When the housing 10 is fitted onto the outside of the water tank 20, the outer wall of the water tank 20 and the inner wall of the housing 10 can be positioned close together, so that the volume of the water tank 20 can be made larger to hold more water.

[0082] In some embodiments, please refer to Figure 3 The bracket 60 has a positioning groove 62, and the bottom of the mesh 30 is located in the positioning groove 62. This allows the mesh 30 to be stably assembled on the bracket 60, which is connected to the top opening 22 of the water tank 20, thereby defining the relative position of the mesh 30 and the housing 10.

[0083] For example, the bracket 60 extends in a circular shape, and the positioning groove 62 is also circular. The mesh fabric 30 is cylindrical and extends vertically, with the bottom of the mesh fabric 30 located in the positioning groove 62.

[0084] In some embodiments, please refer to Figure 5 The bottom surface of the positioning groove 62 is inclined, and the inner edge 62a of the bottom surface of the positioning groove 62 is higher than the outer edge 62b of the bottom surface of the positioning groove 62. The outer wall of the bracket 60 and the inner wall of the water tank 20 are spaced apart. The outer wall of the bracket 60 has a water outlet 63 that communicates with the positioning groove 62.

[0085] The water system assembly 40 transfers water from the water tank 20 to the mesh fabric 30. When there is too much water on the mesh fabric 30, it can fall into the positioning groove 62 of the bracket 60. The water in the positioning groove 62 flows along the bottom surface of the positioning groove 62 from the inner edge 62a to the outer edge 62b, and can be discharged through the outlet 63 towards the inner wall of the water tank 20, and then flow down the inner wall of the water tank 20 back into the water tank 20. The sound of the water flowing is relatively small. This improves the problem of excessive water falling from the inner wall of the positioning groove 62 into the water tank 20, which causes a lot of water flowing noise.

[0086] In some embodiments, the mesh fabric 30 may also be referred to as a wet curtain or humidification component. As a wettable and evaporative substrate for evaporative humidifiers that can retain and evaporate water, it may include a wettable filter material made of hydrophilic polymer composite materials or natural / synthetic fiber fabrics. Its surface may be treated with a nano-coating or gradient porosity to optimize capillary water absorption performance. The wettable filter material can be wetted to form an air-water contact interface with a high specific surface area through a multi-layer composite or three-dimensional honeycomb structure, and may be wetted with antibacterial agents or anti-mildew coatings that resist biofouling. The wettable filter material may be equipped with a support frame integrating guide channels or asymmetric corrugated units to directionally guide the airflow and moisture diffusion path. At the same time, the mesh fabric may have a modular assembly structure and a detachable installation interface that can be adapted to different air supply systems.

[0087] In some embodiments, please refer to Figure 3 It also includes a connecting frame 31, with a mesh fabric 30 disposed on the connecting frame 31, and the bottom of the connecting frame 31 disposed on the support 60. The mesh fabric 30 is assembled on the connecting frame 31, and the connecting frame 31 is assembled on the support 60, thereby reliably assembling the mesh fabric 30 on the support 60. The outer flange 61 of the support 60 abuts against the end face 23 of the water tank 20 at the top opening 22, limiting the support 60 at the top opening 22, resulting in high assembly efficiency.

[0088] In some embodiments, please refer to Figure 3 , Figure 5The connecting frame 31 includes an annular top 311, an annular bottom 312, and a ventilation section 313, with the annular top 311 and the annular bottom 312 connected by the ventilation section 313. The annular top 311 has a water distribution groove 3111, and the bottom surface of the water distribution groove 3111 has seepage holes 3112. The mesh fabric 30 is sleeved outside the ventilation section 313, with its upper end face 30a fitting against the annular top 311 and its lower end face 30b fitting against the annular bottom 312. The annular bottom 312 is mounted in the positioning groove 62 of the bracket 60.

[0089] The water system assembly 40 draws water from the water tank 20 and transfers it to the water distribution trough 3111 of the connecting frame 31. The water in the water distribution trough 3111 falls onto the mesh fabric 30 through the seepage holes 3112, thus wetting the mesh fabric 30. The airflow generated by the fan 50 can pass through the mesh fabric 30 and the ventilation opening 3131 of the ventilation section 313, and the connecting frame 31 does not affect the airflow.

[0090] In other embodiments, the mesh fabric 30 may not have a connecting frame 31 and may be directly assembled onto the bracket 60.

[0091] In other embodiments, the mesh 30 may not be mounted on the bracket 60, but may be mounted in other locations within the housing 10 and located within the airflow channel 10c, such as on the inner wall of the housing 10.

[0092] In some embodiments, please refer to Figure 3 The mesh fabric 30 can be annular. The annular shape can be circular, elliptical, rounded rectangle, rectangular, square, etc. The shape of the mesh fabric 30 can be set according to the shape of the housing 10, so that the mesh fabric 30 is close to the inner wall surface of the housing 10. For example, the cross-section of both the housing 10 and the mesh fabric 30 is annular, the housing 10 is roughly cylindrical, and the mesh fabric 30 is roughly cylindrical.

[0093] In some embodiments, please refer to Figure 3 The water channel component 40 is located in the central area 10a of the casing 10, without affecting the airflow between the mesh fabric 30 and the outside air. The water channel component 40 can draw water 1 from the water tank 20 and transfer it to the mesh fabric 30, thus wetting the mesh fabric 30. The fan 50 generates airflow from the air inlet 11 to the air outlet 12. The casing 10 has air inlets 11 around its perimeter. The airflow around the casing 10 passes through the annular mesh fabric 30 from the outside to the inside, resulting in a relatively uniform airflow volume around the casing 10 and a relatively uniform air pressure distribution inside and outside the mesh fabric 30. The airflow blowing over the wetted mesh fabric 30 causes the moisture in the mesh fabric 30 to vaporize. The evaporation rate is small at different locations on the mesh fabric 30, and the moisture is blown out from the air outlet 12 with the airflow. The mesh fabric 30 has high water evaporation efficiency and good air humidification effect.

[0094] In some embodiments, please refer to Figure 3It also includes a water level sensor 80, which is located within the water circuit assembly 40 and is used to detect the water level in the water tank 20. The water level sensor 80 within the water circuit assembly 40 can detect the water level in the water tank 20.

[0095] In some embodiments, please refer to Figure 3 The water level sensor 80 includes a float 81, a magnet 82, and a Hall sensor 83. The float 81 is movably mounted on the housing 46 of the water circuit assembly 40 in the vertical direction. The magnet 82 is fixed to the float 81, and the Hall sensor 83 is fixed to the housing 46. The magnet 82 and the Hall sensor 83 cooperate to detect the water level of the water tank 20.

[0096] A float 81, with a fixed magnet 82, is movably mounted on the housing 46 of the water circuit assembly 40 and can float freely on the water surface. A Hall sensor 83 converts the changing magnetic field into a change in output voltage. The Hall sensor 83 can be positioned at a predetermined location in the water tank 20. As the water level in the water tank 20 changes, the magnet 82 moves up and down with the float 81. The Hall sensor 83 detects the change in the magnetic field of the magnet 82, thereby detecting the position of the float 81 and achieving water level detection in the water tank 20.

[0097] For example, the Hall sensor 83 is positioned at a high position within the water tank 20. (As...) Figure 4 As shown, when the water level in the water tank 20 is higher than the predetermined position C, that is, when the float 81 with the magnet 82 fixed is higher than the predetermined position C, the Hall sensor 83 can detect the magnetic field of the magnet 82 and determine that the water tank 20 has a certain amount of water.

[0098] like Figure 3 As shown, when the water level in the water tank 20 is lower than the predetermined position C, that is, when the float 81 with the magnet 82 fixed is lower than the predetermined position C, the Hall sensor 83 cannot detect the magnetic field of the magnet 82, and it can be determined that the water level in the water tank 20 is low or there is no water.

[0099] In some embodiments, please refer to Figure 4 The water system assembly 40 includes a water pump 41 and a water pumping channel 40a. The water pump 41 is mounted on the water pumping channel 40a, one end of which is located inside the water tank 20, and the other end of which faces the mesh fabric 30. The water pump 41 and the water pumping channel 40a work together to transfer water 1 from the water tank 20 to the mesh fabric 30 through the water pumping channel 40a, thus wetting the mesh fabric 30.

[0100] The water pump 41 can be located near the center area 10a of the housing 10. There is a lot of water 1 around the water pump 41. The noise generated by the water pump 41 during operation is blocked by the water 1 to a certain extent, reducing the operating noise of the water pump 41 and improving the user experience.

[0101] In some embodiments, please refer to Figure 3The water pumping channel 40a includes an inlet pipe 42 and a heating pipe 43. One end of the inlet pipe 42 is connected to one end of the heating pipe 43. The inlet pipe 42 is located below the heating pipe 43 and is connected to the water pump 41. The heating pipe 43 is provided with a heating element 44.

[0102] When the mesh fabric 30 needs to be wetted, water 1 from water tank 20 is pumped into inlet pipe 42 by water pump 41. After passing through heating pipe 43, the water is transferred to the mesh fabric 30. The water in heating pipe 43 can be heated by heating element 44, so that the heated water 1 wets the mesh fabric 30. When the airflow passes through the wetted mesh fabric 30, the preheated water evaporates more easily, and the moisture is blown out from air outlet 12 with the airflow, enhancing the humidification effect.

[0103] The heating element 44 can be a positive temperature coefficient (PTC) thermistor.

[0104] In some embodiments, please refer to Figure 3 It also includes a controller 90, a Hall sensor 83, and a heating element 44, all electrically connected to the controller 90. The controller 90, Hall sensor 83, and heating element 44 work together, and based on the detection signal of the magnetic field of the magnet 82 by the Hall sensor 83, the controller 90 can determine the water level in the water tank 20.

[0105] When the controller 90 determines that there is a certain amount of water, the controller 90 activates the heating element 44 to heat the water in the heating tube 43. When the controller 90 determines that the water level in the water tank 20 is low or there is no water, the controller 90 stops the heating element 44 from working, to avoid or reduce the possibility of fire caused by the heating element 44 burning dry in the heating tube 43 which is short of water, and to improve the reliability of the heating element 44 and the heating tube 43.

[0106] The controller 90 can be represented as a circuit board assembly and can be set inside the housing 10, for example, inside the housing 10 near the fan 50, avoiding the mesh 30 and the water tank 20.

[0107] In some embodiments, please refer to Figure 3 The housing 46 has a guide groove 461 extending along the height direction Z of the housing 10, within which the float 81 can move. Confining the float 81 within the guide groove 461 causes the magnet 82 to move within a predetermined range, allowing the Hall sensor 83 and the magnet 82 on the float 81 to cooperate in detecting the position of the float 81. The Hall sensor 83 can be fixed to the housing 46.

[0108] In some embodiments, please refer to Figure 3 The water level sensor 80 is located below the heating tube 43 and outside the water inlet pipe 42. This ensures that the water level sensor 80 can operate reliably to detect the water level in the water tank 20.

[0109] In some embodiments, please refer to Figure 3 The heating element 43 is located inside the mesh fabric 30. This makes full use of space, resulting in a smaller overall footprint and a compact structure.

[0110] In some embodiments, please refer to Figure 3 The heating tube 43 and the heating element 44 are integrated into one structure. This allows for convenient assembly of the heating tube 43 and the heating element 44 into the housing 46, with the heating element 44 heating the water inside the heating tube 43.

[0111] In some embodiments, please refer to Figure 3 The heating element 44 is arranged around the outer periphery of the heating tube 43 to improve the heating effect of the water inside the heating tube 43.

[0112] In some embodiments, please refer to Figure 3 The heating element 44 is surrounded by a flame-retardant insulation layer 441. This enhances fire resistance and insulation performance, keeping the heating element 44 insulated and preventing or reducing the occurrence of fires. The flame-retardant insulation layer 441 can surround the heating element 44 to improve the insulation effect. The flame-retardant insulation layer 441 can be made of materials such as rock wool, foam glass, and polyurethane.

[0113] In some embodiments, please refer to Figure 3 Heating element 43 is a metal tube. The metal tube is heat-resistant. When heating element 44 heats the water inside the metal tube, the heat is conducted through the metal tube to the water. The metal tube has high thermal conductivity and does not experience high-temperature aging. The metal tube can be stainless steel, copper, etc.

[0114] In some embodiments, please refer to Figure 3 The inner cavity of the inlet pipe 42 is inverted conical. This can effectively reduce the impact of water pressure on the inlet pipe 42 when the water pump 41 starts operating, which could cause damage due to high internal pressure, thus improving the reliability of the inlet pipe 42.

[0115] In some embodiments, please refer to Figure 3 The inlet pipe 42 is made of plastic or silicone. The inlet pipe 42 can be made of high-temperature resistant plastic or silicone. The plastic can be polyimide, polyphenylene sulfide, polytetrafluoroethylene, etc. The silicone can be high-temperature silicone, high-temperature resistant platinum silicone, high-temperature resistant fluorosilicone, etc.

[0116] In some embodiments, please refer to Figure 7 A sealing connection structure 47 is provided between the water inlet pipe 42 and the heating pipe 43 to achieve a sealed connection between the two pipes.

[0117] For example, the sealing connection structure 47 may include a convex ring 432 and an annular groove 421. The convex ring 432 may be disposed on the outer wall of the constricted section 431, and the annular groove 421 may be disposed on the inner wall of the port of the water inlet pipe 42. When the heating tube 43 is assembled into the water inlet pipe 42, the convex ring 432 may be engaged into the annular groove 421 to achieve a sealed connection between the heating tube 43 and the water inlet pipe 42.

[0118] In some embodiments, please refer to Figure 7 One end of the heating tube 43 is a constricted section 431, which can be inserted into one end of the water inlet pipe 42. The constricted section 431 and the water inlet pipe 42 are tightly fitted. When the constricted section 431 is inserted into the end of the water inlet pipe 42, the end face of the water inlet pipe 42 abuts against the stepped surface 433 of the heating tube 43, thereby achieving the positioning and assembly of the heating tube 43 and the water inlet pipe 42.

[0119] In some embodiments, please refer to Figure 3 The water pumping channel 40a also includes an outlet pipe 45, one end of which is connected to one end of the heating pipe 43, and the other end of which faces the mesh fabric 30. The outlet pipe 45 can extend horizontally, and its end can be located above the mesh fabric 30. The outlet pipe 45 is used to allow water inside the heating pipe 43 to flow to the mesh fabric 30. When the water pump 41 is working, the water in the water tank 20 flows sequentially through the inlet pipe 42, the heating pipe 43, and the outlet pipe 45 to the mesh fabric 30, thus fully wetting the mesh fabric 30.

[0120] In some embodiments, please refer to Figure 3 The water pump 41 and the water pumping channel 40a are installed in the housing 46 of the water circuit assembly 40, and the housing 46 is fixed to the casing 10. The water circuit assembly 40 and the casing 10 are an integral structure. When the water tank 20 is assembled into the casing 10, the water pump 41 of the water circuit assembly 40 is positioned at the bottom of the water tank 20. During the process of the user lifting the casing 10 to separate the casing 10 and the water tank 20, the water circuit assembly 40 follows the casing 10 to separate the water tank 20.

[0121] For example, the water pump 41 can be fastened to the housing 46 using fasteners. The inlet pipe 42 can be snapped onto the housing 46. The two ends of the heating pipe 43 are connected to the inlet pipe 42 and the outlet pipe 45, respectively. The outlet pipe 45 can be snapped onto the housing 46. The wires between the controller 90 and the motor 51, and between the controller 90 and the Hall sensor 83, can be arranged inside the housing 46.

[0122] In some embodiments, please refer to Figure 3 , Figure 4The housing 46 of the water circuit assembly 40 has an opening 462 that connects the interior of the housing 46 to the interior of the water tank 20. The water level sensor 80 is at least partially located inside the housing 46. Water in the water tank 20 can enter the housing 46 through the opening 462, and the water level inside the housing 46 and the water level in the water tank 20 are kept at the same height, so that the water level sensor 80 can detect the water level in the water tank 20.

[0123] In some embodiments, please refer to Figure 3 , Figure 4 An opening 462 is provided at the bottom or side of the housing 46 of the water system assembly 40. This ensures that the water level inside the housing 46 and the water level in the water tank 20 are at the same height.

[0124] For example, opening 462 may be located on the side of housing 46 and extend along the height direction Z of housing 10. Opening 462 allows communication between the interior of housing 46 and the interior of water tank 20.

[0125] In some embodiments, please refer to Figure 3 The water tank 20 is detachably installed at the bottom of the housing 10, with the bottom of the housing 10 fitted over the water tank 20. The water tank 20 is detachable from the housing 10, facilitating cleaning and maintenance of the water tank 20 and other components. The water tank 20 and the housing 10 can be connected using snap-fit, tight-fit, or fastener methods. When the water tank 20 is installed on the housing 10, the housing 10 serves as an exterior component of the entire machine, providing a better aesthetic appearance.

[0126] In other embodiments, the water tank 20 is detachably mounted to the bottom of the housing 10, with the bottom of the housing 10 connected to the upper end of the water tank 20. The water tank 20 is detachable from the housing 10, facilitating cleaning or maintenance of the water tank 20 and other components.

[0127] In some embodiments, please refer to Figure 1 , Figure 3 , Figure 4 Air inlets 11 are distributed around the outer periphery of the casing 10. Air outlets 12 are located at the top of the casing 10. The mesh fabric 30 is annular and is positioned opposite to the air inlets 11. When the fan 50 is working, the airflow around the outer periphery of the casing 10 enters the airflow channel 10c through the air inlets 11. After the airflow passes through the wetted mesh fabric 30 from the outside to the inside, the moisture in the mesh fabric 30 vaporizes and is blown out from the air outlet 12 with the airflow, achieving efficient humidification of the air.

[0128] In some embodiments, please refer to Figure 3The fan 50 can be positioned above the mesh fabric 30. The fan 50 includes a motor 51 and a fan blade 52. The fan blade 52 is mounted on the output shaft of the motor 51 and located on the outer periphery of the motor 51. The motor 51 can drive the fan blade 52 to rotate to generate airflow. The fan 50 can be an axial flow fan, capable of generating airflow along the axial direction. The air inlet side 50a of the fan 50 can be positioned close to the mesh fabric 30, and the air outlet side 50b of the fan 50 can be positioned close to the air outlet 12.

[0129] In some embodiments, please refer to Figure 3 The housing 10 has an air guide wall 14 inside, and the fan 50 is located inside the air guide wall 14. The inner cavity of the air guide wall 14 and the inner cavity of the mesh 30 are connected by an air inlet grille 13. The air outlet 12 is located at the end of the air guide wall 14 away from the air inlet grille 13. The air guide wall 14 can guide the airflow, reduce wind resistance, and increase the air volume. When the fan 50 is working, the airflow around the outer periphery of the housing 10 enters the housing 10 through the air inlet 11, passes through the mesh 30 from the outside to the inside, passes through the air inlet grille 13 and enters the air guide wall 14, and finally exits through the air outlet 12.

[0130] In some embodiments, please refer to Figure 7 The housing 10 has a water filling channel 15, which is arranged adjacent to the fan 50. The top of the water filling channel 15 forms a water inlet 151, and the bottom of the water filling channel 15 is connected to the slot 3113 of the water distribution groove 3111 of the connecting frame 31. When water is poured into the water inlet 151, the water enters the water distribution groove 3111 of the connecting frame 31 through the water filling channel 15, falls onto the mesh 30 through the seepage hole 3112, passes through the outlet 63 of the bracket 60, and finally flows down along the inner wall of the water tank 20 into the water tank 20.

[0131] Please see Figures 1 to 4 This application provides a humidifier 100, including a housing 10, a water tank 20, a mesh fabric 30, a water channel assembly 40, and a fan 50. The housing 10 has an air inlet 11, an air outlet 12, and an airflow channel 10c. The water tank 20 is installed in the housing 10. The mesh fabric 30 is located within the airflow channel 10c; at least a portion of the air outlet 12 and the mesh fabric 30 are on the same arc L1, which is located in the space of the airflow channel 10c. The water channel assembly 40 is used to transfer water 1 from the water tank 20 to the mesh fabric 30. The fan 50 is disposed in the housing 10 and is used to generate airflow from the air inlet 11 to the air outlet 12. The air inlet 11, the air outlet 12, and the airflow channel 10c are connected.

[0132] The beneficial effects of the humidifier 100 provided in this embodiment are as follows: the water circuit assembly 40 can transfer water 1 from the water tank 20 to the mesh fabric 30, thus wetting the mesh fabric 30. The airflow generated by the fan 50 enters the airflow channel 10c through the air inlet 11 and is discharged at the air outlet 12. The airflow blows across the wetted mesh fabric 30, and the moisture in the mesh fabric 30 vaporizes and is blown out from the air outlet 12 with the airflow, thereby humidifying the air. The air outlet 12 and the mesh fabric 30 are located on the same arc L1, which is located in the space of the airflow channel 10c. The airflow driven by the fan 50 passes through the wetted mesh fabric 30 along the arc-shaped airflow path. The arc layout optimizes the space utilization of the airflow channel, reduces energy loss caused by airflow vortices, and thus improves the water evaporation efficiency and enhances the humidification capacity. It also reduces the working resistance of the fan 50, reducing energy consumption and noise. It achieves a dual optimization of efficient humidification and energy saving and noise reduction.

[0133] In some embodiments, please refer to Figure 3 , Figure 4 , Figure 9 In the height direction Z of the housing 10, the projection of the air outlet 12 and the projection of the mesh 30 at least partially overlap. The airflow blows over the wet mesh 30, the moisture in the mesh 30 vaporizes, and the airflow carrying moisture flows along the airflow channel 10c and is discharged at the air outlet 12, achieving stable and low-resistance airflow, reducing the turning of the airflow in different directions, and improving the overall humidification efficiency.

[0134] It is understandable that the humidifier 100 in this embodiment can adopt the humidifier 100 solution mentioned in the previous embodiment, which will not be repeated here.

[0135] Below are multiple sets of comparative tests on the humidifier of this embodiment and the comparative humidifier. Among them, the comparative humidifier is the aforementioned related technology humidifier.

[0136] The first group is a comparative test of the humidification capacity of humidifiers at different speeds and temperatures. Different speeds refer to the airflow levels. The higher the speed, the greater the airflow. Speed ​​1 is the lowest speed. Cold mist indicates the condition without the heating element on. Hot mist indicates the condition with the heating element on, heating the water. In this embodiment and the comparative humidifier, a wet mesh cloth was used. After turning on the water pump and running the humidifier for 15 minutes, the humidification capacity was tested. The results are shown in Table 1 below:

[0137] Test conditions Test environment Humidification rate (ml / h) in this embodiment Comparative humidification rate (ml / h) Third gear, cold mist A room at 21°C with humidity between 48% and 55%. 334 154 Three-speed setting, hot mist A room at 21°C with humidity between 48% and 55%. 680 480 First gear, cold fog A room at 21°C with humidity between 48% and 55%. 178 ——

[0138] The unit for humidification is milliliters per hour (ml / h).

[0139] As can be seen from Table 1, compared with the comparative humidifier, the humidifier in this embodiment has a larger humidification capacity and better humidification effect at different settings and temperatures.

[0140] The second group involved a comparative test of the humidification capacity of humidifiers at different speeds and temperatures. After the humidifiers in this embodiment and the comparative humidifier had been running for a predetermined time, such as 60 minutes, their humidification capacity was tested. The results are shown in Table 2 below:

[0141]

[0142] The unit for humidification is milliliters per hour (ml / h).

[0143] As can be seen from Table 2, compared with the comparative humidifier, the humidifier in this embodiment has a larger humidification capacity at different speeds and temperatures, and the humidification effect is better.

[0144] The third group consisted of a noise comparison test of humidifiers at different speeds and temperatures. The results are shown in Table 3 below:

[0145]

[0146] The unit for noise is decibel (dB).

[0147] As can be seen from Table 3, compared with the comparative humidifier, the humidifier in this embodiment has a relatively low noise level at different speeds and temperatures or when only the water pump is turned on.

[0148] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
