[0049] To make the purposes, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application. The embodiments described below and the features in the embodiments can be combined with each other without conflict.

[0050] Please refer to Figure 1 The embodiments of the present application provide a humidifier 10, which can be a mist-free humidifier 10. The mist-free humidifier 10 generally includes a humidifier host 100, a filter element assembly 200, and a water tank 300. The water tank 300 is arranged above the humidifier host 100, and the filter element assembly 200 is arranged between the humidifier host 100 and the water tank 300.

[0051] The water tank 300 is used to store humidification water of the humidifier 10. The humidification water in the water tank 300 can be pure water, or can be a water solution with additives such as mixed spices, bactericides, essential oils, etc. The embodiments of the present application do not make specific limitations on this, and the liquid used for the humidification filter element 210 will be collectively referred to as water below, and will not be specifically described.

[0052] In some embodiments, the humidifier host 100 includes a host shell 110, a motor, and a fan. The host shell 110 has a containing cavity, the motor and the fan are located in the containing cavity, and the fan is connected with an output shaft of the motor. The host shell 110 has an air inlet hole on a side wall thereof. The filter element assembly 200 includes a filter element 210. The bottom wall of the water tank 300 has a closable drain hole. When the drain hole is opened, the humidification water in the water tank 300 drips through the drain hole and flows to the filter element 210 to wet the filter element 210. In this way, when the motor is started, the fan is driven to run, the running of the fan can improve the flowability of air, the flowing air passes through the wetted filter element 210, so that the moisture on the filter element 210 is naturally evaporated into the air under the flow of the air, thereby increasing the humidity of the air. In addition, this humidification method can avoid the generation of visible water mist, thereby reducing the deposition of visible water mist on furniture, reducing bacterial breeding, and also avoiding the potential damage of water mist deposition to furniture and floor.

[0053] In some embodiments, please refer to Figure 1 and Figure 2As shown, the filter core assembly 200 further comprises an air outlet piece 220, which has a supporting portion 221 surrounding the outer circumferential side of the filter core 210 to support the filter core 210 through the supporting portion 221 to improve the stability of the filter core 210; for example, the filter core 210 can have a circular, elliptical, polygonal or any other shape in cross-sectional profile, and thus the supporting portion 221 has a profile matching that of the filter core 210.

[0054] In some embodiments, the air outlet piece 220 further has a grating portion 222 covering the air outlet end of the filter core 210 and connected with the supporting portion 221, so that the airflow blown to the filter core 210 can flow out through the grating portion 222 to increase the humidity of the air.

[0055] It should be noted that the filter core 210 has an air inlet end and an air outlet end, wherein the air inlet end of the filter core 210 is the end where the airflow is blown to the filter core 210, and the air outlet end is the end where the airflow passing through the filter core 210 flows out of the filter core 210, for example, in Figure 1 , the end of the filter core 210 facing the humidifier main machine 100 is the air inlet end of the filter core 210, and the end of the filter core 210 facing the water tank 300 is the air outlet end.

[0056] It can be understood that the grating portion 222 has an air outlet 2222, and the airflow passing through the filter core 210 can flow out through the air outlet 2222 on the grating portion 222 to increase the humidity of the air.

[0057] In the embodiments of the present application, the air outlet piece 220 not only provides a supporting basis for the filter core 210, but also serves as an air outlet structure for the airflow on the filter core 210, so that the air outlet piece 220 has a certain air outlet area, that is, in the embodiments of the present application, the supporting piece for supporting the filter core 210 and the grating piece for air outlet of the filter core 210 are designed as one part, so that this one part not only realizes the supporting effect of supporting the filter core 210, but also ensures a certain air outlet area, thereby simplifying the structure of the filter core assembly 200, reducing the number of parts, improving the structural compactness of the humidifier 10, and reducing the cost.

[0058] In some embodiments, please refer to Figures 2 to 5 As shown, the grating portion 222 has a plurality of air guide grating strips 2221, which are arranged at intervals along the circumferential direction of the filter core 210, and one end of each air guide grating strip 2221 is connected with the supporting portion 221, and the other end is connected with the adjacent air guide grating strip 2221, and an air outlet 2222 is formed between any two adjacent air guide grating strips 2221 to make the airflow blown to the filter core 210 flow out through the air outlet 2222, so that the air outlet area of the grating portion 222 can be increased, and the smoothness and efficiency of the air outlet are improved, thereby improving the humidification efficiency of the humidifier 10.

[0059] For example, the filter element 210 has a circular cross-sectional profile in the horizontal direction, and the plurality of air guide bars 2221 are arranged equidistantly along the circumferential direction of the filter element 210 at the air outlet end of the filter element 210, so that the air outlet area is increased, and the uniformity of the air outlet in the circumferential direction of the filter element 210 is improved.

[0060] In addition, the cross-sectional shape of the air guide bar 2221 can be circular, square, oval, polygonal, or any other shape, which is not limited herein.

[0061] In some embodiments, please continue to refer to Figures 2 to 5 As shown, the air guide bar 2221 includes a first sub-bar 2221a and a second sub-bar 2221b, the first sub-bar 2221a is connected between the support portion 221 and the second sub-bar 2221b, and the first sub-bar 2221a and the second sub-bar 2221b have an included angle therebetween, for example, the first sub-bar 2221a is bent toward one side of the support portion 221 relative to the second sub-bar 2221b, so that the air outlet area of the air outlet 2222 is further increased, so that the airflow passing through the filter element 210 is not only out of the end face of the air outlet end of the filter element 210, but also out of the side wall near the air outlet end of the filter element 210, thereby improving the efficiency of increasing the air humidity.

[0062] In some embodiments, as shown in Figure 2 The extension direction of the second sub-bar 2221b has an included angle with the first direction, wherein the first direction is perpendicular to the height direction of the filter element 210, for example, when the profile shape of the filter element 210 is circular, the first direction can be the radial direction of the filter element 210, for example, in Figure 2 The first direction represents one radial direction of the filter element 210, wherein the second sub-bar 2221b has an included angle with any radial direction of the filter element 210, so that the airflow at the air outlet end of the filter element 210 is guided by the extension direction of the second sub-bar 2221b, so as to improve the air outlet efficiency, thereby improving the humidification efficiency of the humidifier 10.

[0063] In addition, each air guide bar 2221 can be provided with an air guide slope configured to guide the airflow out of the air outlet 2222, so as to further improve the directionality of the air outlet, in addition, the resistance during the air outlet can be reduced, the air outlet efficiency is improved, thereby improving the humidification efficiency of the humidifier 10.

[0064] In some embodiments, two ends of each air guide grid 2221 are movably connected with the support part 221 and the adjacent air guide grid 2221 respectively, so that at least one of the size and direction of the air outlet 2222 is adjustable, so that the size and direction of the air outlet 2222 can be adjusted according to the air outlet demand to adapt to different occasions and different demand humidification requirements, thereby improving the humidification effect and user experience.

[0065] In addition, when the humidifier 10 is in an idle state, the air guide grid 2221 can be rotated to close the air outlet 2222, so that dust particles and the like can be prevented from entering the filter element 210; when the humidifier 10 needs to be operated, the air guide grid 2221 is reversed to adjust the opening of the air outlet 2222 to the appropriate size to meet the air outlet demand of the user.

[0066] In some embodiments, the plurality of air guide grids 2221 can be independent of each other or associated with each other. When the plurality of air guide grids 2221 are independent of each other, a single air guide grid 2221 can be rotated individually, so that the rotation angles of the air guide grids 2221 at different positions can be different, thereby enabling the opening size or direction of the air outlet 2222 at different positions to be different to meet the local air outlet demand. If the plurality of air guide grids 2221 are associated with each other, rotating one air guide grid 2221 can cause the other air guide grids 2221 to rotate synchronously, and the opening size and direction of each air outlet 2222 are always consistent, so that the efficiency of adjusting the opening size or direction of each air outlet 2222 can be improved.

[0067] In order to further increase the air outlet area, the air guide grid 2221 can be in a sheet structure to further increase the area of the air outlet 2222 and reduce the air outlet resistance, thereby improving the air outlet efficiency.

[0068] In some embodiments, please refer to Figure 2 and Figure 3 As shown in the drawings, the filter element 210 is in a ring structure; the air outlet part 220 further has a wind blocking part 223 surrounding the inner wall surface of the filter element 210 and connected with the grid part 222, so that the air passing through the filter element 210 can be prevented from flowing out through the inner side wall of the filter element 210 to affect the humidification efficiency and effect. By providing the wind blocking part 223 on the inner wall surface of the filter element 210, the wind blocking part 223 can block the airflow so that all the airflow passing through the filter element 210 flows out through the grid part 222, thereby further improving the air outlet efficiency of the air outlet grid and improving the humidification efficiency of the humidifier 10.

[0069] In some embodiments, one end of each air guide grille bar 2221 facing away from the support portion 221 may be directly connected to an adjacent air guide grille bar 2221, or may be indirectly connected to an adjacent air guide grille bar 2221. Exemplarily, one end of each air guide grille bar 2221 facing away from the support portion 221 is connected to the wind shield portion 223, that is, one end of each air guide grille bar 2221 facing away from the support portion 221 is indirectly connected to an adjacent air guide grille bar 2221 through the wind shield portion 223, thereby fixing the air guide grille bar 2221 between the support portion 221 and the wind shield portion 223.

[0070] In some embodiments, the wind shield portion 223 encloses to form a liquid storage tank 224. The water in the water tank 300 can directly drip into the liquid storage tank 224 through the water outlet holes. A plurality of water outlet holes 225 are provided on the side wall of the liquid storage tank 224, and the plurality of water outlet holes 225 are arranged at intervals along the circumferential direction of the liquid storage tank 224, so that the water in the water storage tank seeps into the filter element 210 through the water outlet holes 225. The water dripping into the liquid storage tank 224 can seep into the filter element 210 through the water outlet holes 225 to humidify the filter element 210. At the same time, the humidification uniformity of the filter element 210 can be improved, and thus the effective humidification area of the filter element 210 can be increased.

[0071] In some embodiments, the bottom of the liquid storage tank 224 has a diversion structure 226, and the diversion structure 226 is configured to divert the water in the liquid storage tank 224 to each water outlet hole 225. In this way, the water flow to the filter element 210 through the water outlet holes 225 can be accelerated, so as to improve the efficiency of the water seeping into the filter element  210, improve the humidification efficiency of wetting the filter element 210, and thus improve the humidification efficiency of the humidifier 10.

[0072] Exemplarily, as Figure 3 shown, the bottom of the liquid storage tank 224 has a conical protrusion, and the conical surface of the conical protrusion forms a diversion structure 226. When water drops onto the conical protrusion at the bottom of the tank, the water can be diverted along the conical surface of the conical protrusion to the surrounding water outlet holes 225. In this way, the uniformity of the water flowing to the periphery of the liquid storage tank 224 can be improved, and the diversion structure 226 is simple, easy to implement, and has low cost.

[0073] In some embodiments, when the guide grille bars in the grille portion 222 are fixed relative to the support portion 221, the support portion 221, the grille portion 222 and the wind shield portion 223 are one of an injection-molded integral structure or a cast integral structure, which improves the structural compactness of the air outlet member 220 and reduces the installation process of the air outlet member 220, thereby reducing the process cost.

[0074] [[ID=十七]]In other embodiments, both ends of each guide grille bar may be welded, adhered, clamped or magnetically connected to the support portion 221. There is no specific limitation as long as each guide grille bar is relatively fixed to the support portion 22, and no limitation is made here.

[0075] In some embodiments, the filter assembly 200 further comprises a water storage tray horizontally arranged in the main machine housing 110 and sealingly connected with the cavity wall of the accommodating cavity, the water storage tray is located above the motor and the fan, the water storage tray comprises a water storage groove and an air outlet grille arranged around the water storage groove, the bottom of the filter core 210 has a submergence level 211, the submergence level 211 is located in the water storage groove, so that the water remaining on the filter core 210 flows into the water storage groove along the submergence level, to prevent the water from entering the humidifier main machine 100 through the air outlet grille.

[0076] In addition, as shown in Figure 3 The filter assembly 200 further comprises a filter core lower cover 250, so that the filter core 210 can be further stabilized by the filter core lower cover serving as a support for the filter core 210, and in addition, the filter core lower cover is arranged around the inner side wall of the filter core 210 and detachably connected with the wind blocking part 223, the filter core lower cover 250 arranged around the inner side wall of the filter core 210 has the same effect as the wind blocking part 223, that is, it can prevent the airflow passing through the filter core 210 from flowing out along the inner side wall of the filter core 210, so as to guide the airflow to flow out along the grille part 222.

[0077] In addition, another part of the filter core lower cover 250 is located below the submergence level 211 to support the filter core 210, and the filter core lower cover 250 has a through hole communicating the submergence level 211 and the water storage groove, so that the water on the filter core 210 can flow into the water storage groove through the through hole.

[0078] For example, the filter core lower cover 250 can be detachably connected with the wind blocking part 223 by clamping, magnetic connection or the like, so as to facilitate the disassembly and assembly of the filter core lower cover 250 and the wind blocking part 223, to realize the detachable connection of the filter core lower cover 250 and the air outlet member 220.

[0079] In addition, the support part 221 and the main machine housing 110 can be detachably connected by clamping, magnetic connection or the like, that is, the main machine housing 110 is arranged around the outer periphery of the filter core 210 and connected with the support part 221, to avoid exposure of the filter core 210, so as to improve the overall aesthetics of the humidifier.

[0080] In some embodiments, a switch valve is arranged in the drain hole, the switch valve has a valve rod, the valve rod is arranged in the drain hole, one end of the valve rod located in the water tank 300 has a blocking part, the valve rod can move in the drain hole, so that the blocking part is blocked or removed from the drain hole, to close or open the drain hole by the blocking part.

[0081] In some embodiments, the humidifier 10 further comprises a float disposed in the water storage tank, so that the float can float up and down with the change of the water level in the water storage tank; in addition, the humidifier 10 further comprises a driving mechanism configured to drive the movement of the valve rod in the drain hole, for example, the driving mechanism comprises a top rod 230 and a connecting rod 240 connected with the top rod 230, the top rod 230 penetrates the bottom wall of the liquid tank 224 and is connected with the valve rod, the first end of the connecting rod 240 is connected with the end of the top rod 230 away from the valve rod, the second end of the connecting rod 240 is disposed on the float, and the side wall of the connecting rod 240 is provided with a rotating shaft, and the outer bottom wall of the liquid tank 224 has a boss, and the connecting rod 240 is rotatably connected with the boss through the rotating shaft.

[0082] In addition, the end of the valve rod away from the blocking part has a limiting part, and the first elastic member is arranged between the limiting part and the outer bottom wall of the water tank 300, and the first elastic member includes but is not limited to a spring; the end of the top rod 230 towards the valve rod has a first limiting structure, and the end of the valve rod towards the connecting rod 240 has a second limiting structure, and the second elastic member is arranged between the first limiting structure and the inner bottom wall of the liquid tank 224, and the second elastic member includes but is not limited to a spring.

[0083] When the water in the water storage tank is insufficient to float the float, the connecting rod 240 drives the valve rod to move upward through the top rod 230, at this time, the blocking part opens the drain hole, so that the water in the water tank 300 drops into the liquid tank 224 through the drain hole, and the water in the liquid tank 224 flows into the filter core 210 through the four water outlets 225 respectively, and the excess water on the filter core 210 flows into the water storage tank along the filter core 210, and as the water level in the water storage tank rises, the float moves upward, and when the upper end surface of the float contacts the second end of the connecting rod 240, the connecting rod 240 rotates around the rotating shaft, so that the connecting rod 240 drives the valve rod to move downward along the vertical direction through the top rod 230, until the water level in the water storage tank reaches a certain height, the blocking part blocks the drain hole, at this time, the first elastic member is in a free state, and the second elastic member is in a compressed state, and the valve rod moves to the side of the top rod 230 under the pushing of the valve rod by the elastic force of the first elastic member, so as to improve the connection tightness between the blocking part and the drain hole, thereby improving the sealing performance of the drain hole, and the water tank 300 temporarily stops discharging water through the drain hole, and the fan drives the air flow under the driving of the motor, so as to blow the air flow to the filter core 210 through the air outlet grille, so that the water on the filter core 210 is naturally evaporated into the air under the action of the air flow, so as to humidify the air.

[0084] The blocking part can be a blocking structure formed by rubber, plastic or the like having a sealing function, and can realize the function of blocking and sealing the drain hole; for example, the blocking part can be sleeved on the end of the valve rod, so as to facilitate replacement of the blocking part.
