[0001] This application belongs to the field of air humidification technology, and particularly relates to a humidifier. Background Technology

[0002] Current evaporative humidifiers consist of a water tank, a water pump, a mesh fabric, and a fan. The water pump draws water from the water tank to wet the mesh fabric, and the airflow generated by the fan passes through the mesh fabric, causing the moisture on the mesh fabric to evaporate and be blown out with the airflow, thus humidifying the air.

[0003] How to provide a humidifier that prevents the water in the tank from overflowing when placed at a certain angle is a challenge that the industry needs to address. Utility Model Content

[0004] This application provides a humidifier in which the water at a high level in the water tank does not easily overflow when the humidifier is placed at a certain angle.

[0005] This application provides a humidifier, including a housing, a water tank, a bracket, a mesh fabric, a water circuit assembly, and a fan. The housing has an air inlet, an air outlet, and an airflow channel. The water tank is installed on the housing and has a top opening. The bracket is located at the top opening, and a sealing element is provided between the bracket and the water tank. The mesh fabric is disposed on the bracket and located within the airflow channel. The water circuit assembly is used to draw water from the water tank and transfer it to the mesh fabric. The fan is located on the housing and is used to generate an airflow from the air inlet to the air outlet.

[0006] In one implementation, the bracket and the seal are annular, with the seal fitted over the bracket.

[0007] In one implementation, the bracket has an outward flange, and along the height direction of the housing, the seal is sandwiched between the end face of the water tank at the top opening and the outward flange.

[0008] In one implementation, the outward flange is positioned below the air inlet in the height direction of the housing.

[0009] In one implementation, the support is located on the inner periphery of the top opening.

[0010] In one implementation, the bracket has a positioning groove, and the bottom of the mesh fabric is disposed in the positioning groove.

[0011] In one implementation, the bottom surface of the positioning groove is inclined, the inner edge of the bottom surface of the positioning groove is higher than the outer edge of the bottom surface of the positioning groove, the outer wall of the bracket and the inner wall of the water tank are spaced apart, and the outer wall of the bracket has a water outlet communicating with the positioning groove.

[0012] In one implementation, a connecting frame is further included, the mesh is disposed on the connecting frame, and the bottom of the connecting frame is disposed on the support.

[0013] In one implementation, the water circuit assembly includes a water pump and a pumping channel, the water pump being disposed on the pumping channel, one end of the pumping channel being disposed inside the water tank, and the other end of the pumping channel facing the mesh fabric.

[0014] In one implementation, the water tank is detachably mounted on the bottom of the housing, and the bottom of the housing is fitted over the water tank.

[0015] The beneficial effects of the humidifier provided in this application embodiment are as follows: a bracket is installed at the top opening of the water tank, the mesh is placed on the bracket and located in the airflow channel of the casing, and a sealing element is installed between the bracket and the water tank to achieve a waterproof seal between the bracket and the water tank. When the humidifier is placed at a certain angle (e.g., 10° to 20°), such as when the user's table is not horizontal, the water at the high water level in the water tank can be blocked by the sealing element and is not likely to overflow through the gap between the bracket and the water tank. The water circuit assembly can draw water from the water tank and transfer it to the mesh, thus wetting the mesh. The airflow generated by the fan enters the airflow channel through the air inlet and is discharged through the air outlet. The airflow blows over the wet mesh, the moisture in the mesh vaporizes and is blown out from the air outlet with the airflow, thereby humidifying the air. Attached Figure Description

[0028] Please see Figures 1 to 4This application provides a humidifier 100, including a housing 10, a water tank 20, a mesh fabric 30, a water circuit assembly 40, a fan 50, and a bracket 60. The housing 10 has an air inlet 11, an air outlet 12, and an airflow channel 10c. The water tank 20 is mounted on the housing 10 and has a top opening 22. The bracket 60 is located at the top opening 22, and a sealing element 70 is provided between the bracket 60 and the water tank 20. The mesh fabric 30 is disposed on the bracket 60 and located within the airflow channel 10c. The water circuit assembly 40 is used to draw water from the water tank 20 and transfer it to the mesh fabric 30. The fan 50 is disposed on 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.

[0029] The humidifier 100 provided in this embodiment has a bracket 60 installed at the top opening 22 of the water tank 20. A mesh fabric 30 is mounted on the bracket 60 and located within the airflow channel 10c of the housing 10. A sealing element 70 is installed between the bracket 60 and the water tank 20 to achieve a waterproof seal between them. Figure 5 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 at the high water level in the water tank 20 can be blocked by the seal 70, and is less likely to overflow through the gap between the bracket 60 and the water tank 20. Figure 6 The water system component 40 draws water 1 from the water tank 20 and transfers it 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 through the air outlet 12. The airflow blows across the wetted mesh fabric 30, causing the moisture in the mesh fabric 30 to vaporize and be blown out from the air outlet 12 along with the airflow, thereby humidifying the air.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] In some embodiments, please refer to Figure 4 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.

[0037] In some embodiments, please refer to Figure 4 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.

[0038] In some embodiments, please refer to Figure 4 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.

[0039] 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.

[0040] 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.

[0041] In some embodiments, please refer to Figure 4 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.

[0042] The water system assembly 40 transfers water from the water tank 20 to the mesh fabric 30. When there is excess water on the mesh fabric 30, it falls 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. It then flows down the inner wall of the water tank 20 and back into the water tank 20, resulting in relatively quiet water flow. This improves the problem of excessive water falling from the inner wall of the positioning groove 62 into the water tank 20, which causes significant water flow noise.

[0043] In some embodiments, please refer to Figure 3 It also includes a connecting frame 31, with the 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.

[0044] In some embodiments, please refer to Figure 3 , Figure 4The 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.

[0045] 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.

[0046] In other embodiments, the mesh fabric 30 may not have a connecting frame 31 and may be directly assembled onto the bracket 60.

[0047] 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.

[0048] In some embodiments, please refer to Figure 6 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] In some embodiments, please refer to Figure 3 The 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.

[0053] 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.

[0054] 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.
