[0054] To make the objectives, technical solutions, and superiorities of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall into the protective scope of the present application. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0055] The embodiments of the present application provide a humidifier, which includes but is not limited to a mist-free humidifier. The structure and working principle of the humidifier will be described in detail below taking the mist-free humidifier as an example.

[0056] Please refer to Figure 1 and Figure 2 The humidifier 10 provided by the embodiments of the present application includes a humidifier host 100, a filter core assembly 200, and a water tank 300. The water tank 300 is arranged above the humidifier host 100, and the filter core assembly 200 is arranged between the humidifier host 100 and the water tank 300. The water tank 300 is used to store humidifying water of the humidifier 10. The humidifying 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 humidifying filter core 220 will be collectively referred to as water, and will not be specifically described.

[0057] In some embodiments, referring to Figure 2 and Figure 3 As shown in the drawings, the filter assembly 200 comprises a filter support 210 and a filter 220, the filter 220 is installed on the filter support 210 to provide a support base for the filter 220 to improve the strength and stability of the filter 220; for example, the filter support 210 comprises an upper filter cover 211 and a lower filter cover 212, the filter 220 is fixed between the upper filter cover 211 and the lower filter cover 212, wherein the filter 220 has an air inlet end and an air outlet end, when the filter 220 is vertically installed between the humidifier main machine 100 and the water tank 300, the lower filter cover 212 is below the upper filter cover 211, then the end of the filter 220 towards the lower cover is the air inlet end, and the end of the filter 220 towards the water tank 300 is the air outlet end, therefore, the lower filter cover 212 has an air inlet 214, and the upper filter cover 211 has an air outlet 215; in addition, the filter support 210 has a liquid containing groove 218, the filter 220 is surrounded by the outer circumferential side of the liquid containing groove 218, the groove wall of the liquid containing groove 218 has a plurality of water outlets, the plurality of water outlets are arranged in a circumferential direction of the liquid containing groove 218; the bottom wall of the water tank 300 has a closable lower water hole, when the lower water hole is opened after water is added to the water tank 300, the water in the water tank 300 drips into the liquid containing groove 218 through the lower water hole, and flows to the filter 220 along the water outlets around the liquid containing groove 218 to wet the filter 220, without the need to additionally set a water pump to pump the water in the water tank 300 to the filter assembly 200, thereby avoiding the noise generated when the water pump works, and improving the user experience; in addition, the problem of increasing the overall cost of the humidifier 10 due to the setting of the water pump is avoided, the cost is saved, and the economy of the humidifier 10 is improved.

[0058] In addition, the humidifier main machine 100 comprises a main machine shell 110 and a fan assembly 120, the main machine shell 110 has a containing cavity, the side wall of the main machine shell 110 has an air inlet hole 111 communicating with the containing cavity, so that external air can enter the containing cavity through the air inlet hole 111, the fan assembly 120 is arranged in the containing cavity, the fan assembly 120 comprises a motor 121 and a fan 122, when the motor 121 is powered on and started, it is used to drive the fan 122 to rotate, when the fan 122 operates, it can drive air flow, in the humidifier main machine 100, one end of the air flow flowing out is the air outlet end of the humidifier main machine 100, the air flow (wind) blown out of the air outlet end blows towards the wet filter 220, in this way, when the air flow passes through the wet filter 220, the moisture on the filter 220 can evaporate naturally in the process of air flow and flow to the air along with the air flow through the air outlet 215, 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 the breeding of bacteria, and also avoiding the potential damage of water mist deposition to furniture and floor.

[0059] It can be understood that the larger the effective area of the filter element 220 through which the air flow blowing to the filter element 220 passes after the filter element 220 is wetted, the better the humidification effect.

[0060] Since the cross section of the filter element 220 between the filter element upper cover 211 and the filter element lower cover 212 flows when the air flows, part of the air flow blowing to the filter element 220 will flow out along the side wall of the filter element 220, and the air flow blown out of the air outlet end of the humidifier main machine 100 cannot effectively pass through the wetted filter element 220 and then flow out through the air outlet 215, that is, the flowing air flow blowing to the filter element 220 will flow out through the non-effective air outlet area of the filter element 220, thereby causing large air flow loss, and further causing the technical problems of low humidification efficiency and poor humidification effect of the humidifier 10.

[0061] Among them, the effective air outlet area of the filter element 220 is, for example, the area corresponding to the air outlet 215, and the non-effective air outlet area of the filter element 220 is, for example, the area of the filter element 220 corresponding to the non-air outlet 215.

[0062] In view of the above problems, in the embodiments of the present application, please refer to Figure 2 and Figure 4 As shown, the filter element support 210 has a separate air duct 213, the air inlet 214 is connected to the air outlet end of the humidifier main machine 100 and the air duct 213, the air outlet 215 is arranged at one end of the air duct 213 away from the air inlet 214 and is connected to the air duct 213, and the filter element 220 is arranged in the air duct 213. In this way, when the humidifier main machine 100 is running, the air blown out of the air outlet end directly enters the air duct 213 through the air inlet 214 on the filter element support 210, and the air entering the air duct 213 can effectively pass through the wetted filter element 220 and then flow out through the air outlet 215, thereby reducing the air flow blowing to the filter element 220 flowing out along the non-air outlet area of the filter element 220, and improving the humidification efficiency and humidification effect of the humidifier 10.

[0063] Among them, the filter element 220 can match the air duct 213, that is, the filter element 220 fills the space in the air duct 213, so that the area of the filter element 220 can be increased, and when the filter element 220 is wetted, the effective humidification area of the filter element 220 can be improved, thereby further improving the humidification efficiency and humidification effect.

[0064] In some embodiments, the air duct 213 is arranged in the extension direction of the air outlet end of the humidifier main machine 100, for example, the air outlet end of the humidifier main machine 100 is the end of the humidifier main machine 100 close to the filter core assembly 200, and the air duct 213 extends upward in the vertical direction, so that the airflow blown by the fan 122 can enter the filter core 220 from the air inlet 214 below the filter core 220, and the airflow entering the filter core 220 passes through the wet filter core 220 from bottom to top in the air duct 213, thereby reducing the loss of the airflow blown by the fan 122 to the filter core 220, and further improving the humidification efficiency and humidification effect of the humidifier 10.

[0065] Please continue to refer to Figure 2 As shown in the figure, the filter core support 210 has a first wind blocking part 216 and a second wind blocking part 217, the first wind blocking part 216 is arranged to form a ring structure, for example, the first wind blocking part 216 is arranged to form a cross section in the horizontal direction in the shape of a circle, an ellipse or a polygon, etc., and the second wind blocking part 217 is arranged on the outer circumferential side of the first wind blocking part 216, the first wind blocking part 216 and the second wind blocking part 217 together form the air duct 213 in the shape of a ring, and the shape of the filter core 220 matches the shape of the air duct 213, so that the filter core 220 is arranged in the air duct 213 in the shape of a ring, on the one hand, the effective area of the filter core 220 can be increased, and on the other hand, the first wind blocking part 216 and the second wind blocking part 217 can block the wind on the inner and outer sides of the filter core 220, so as to prevent the wind blown to the filter core 220 from flowing out through the non-air outlet area of the inner and outer side walls of the filter core 220, thereby reducing the air outlet loss and further improving the humidification efficiency and humidification effect.

[0066] In order to facilitate the disassembly of the filter core 220, in some embodiments, please refer to Figures 2 to 4 As shown in the figure, the filter core support 210 includes a filter core upper cover 211 and a filter core lower cover 212, the filter core upper cover 211 has a first wind blocking plate 2111 and a first support shell 2112, the filter core lower cover 212 has a second wind blocking plate 2121 and a second support shell 2122, the filter core upper cover 211 and the filter core lower cover 212 are arranged oppositely, and the first wind blocking plate 2111 and the second wind blocking plate 2121 are detachably connected and together form the first wind blocking part 216; the first support shell 2112 and the second support shell 2122 are detachably connected and together form the second wind blocking part 217, so that the filter core upper cover 211 and the filter core lower cover 212 are detachably connected, so as to facilitate the disassembly of the filter core 220 installed between the filter core upper cover 211 and the filter core lower cover 212, thereby improving the user's experience.

[0067] It can be understood that, by connecting the filter core upper cover 211 and the filter core lower cover 212 in a detachable manner, the filter core 220 can be conveniently disassembled, and the integrity of the filter core assembly 200 in a non-disassembled state can be improved, so as to prevent the components in the filter core assembly 200 from falling off when the humidifier 10 is tilted.

[0068] For example, the first wind deflector 2111 is annularly arranged, the second wind deflector 2121 is annularly arranged to match the first wind deflector 2111, and the second wind deflector 2121 is arranged below the first wind deflector 2111 and detachably connected to the first wind deflector 2111. The first support shell 2112 and the second support shell 2122 are arranged on the outer circumferential sides of the first wind deflector 2111 and the second wind deflector 2121, respectively, and the second support shell 2122 is arranged below the first support shell 2112 and detachably connected to the first support shell 2112. The first wind deflector 2111 and the second wind deflector 2121 can be detachably connected by clamping, magnetic attraction, or insertion. Similarly, the first support shell 2112 and the second support shell 2122 can be detachably connected by clamping, magnetic attraction, or insertion. The detachable connection is simple, easy to implement, and low in cost.

[0069] In some embodiments, as shown in Figure 5 The end of the first wind deflector 2111 facing the second wind deflector 2121 has a first clamping portion 2114, and the end of the second wind deflector 2121 facing the first wind deflector 2111 has a second clamping portion 2125. In this way, the first wind deflector 2111 and the second wind deflector 2121 are clamped by the first clamping portion 2114 and the second clamping portion 2125. In addition, the end of the first support shell 2112 facing the second support shell 2122 has a third clamping portion 2115, and the end of the second support shell 2122 facing the first support shell 2112 has a fourth clamping portion 2126. In this way, the first support shell 2112 and the second support shell 2122 are clamped by the third clamping portion 2115 and the fourth clamping portion 2126.

[0070] For example, the first clamping portion 2114 is one of a clamping protrusion and a clamping groove, and the second clamping portion 2125 is the other of the clamping protrusion and the clamping groove. In addition, the third clamping portion 2115 is one of a clamping protrusion and a clamping groove, and the fourth clamping portion 2126 is the other of the clamping protrusion and the clamping groove. The structure is simple, the detachable connection is simple and easy to operate, and the cost is low.

[0071] In some embodiments, as shown in Figures 2 to 4As shown, the filter core upper cover 211 further comprises an air outlet portion 2113, which is arranged at the end of the filter core 220 away from the humidifier main machine 100 and connected with the first air baffle 216 and the first support shell 2112 respectively. The air outlet portion 2113 has a plurality of air outlets 215, which are arranged at intervals along the circumference of the filter core 220. In this way, the air passing through the wet filter core 220 can flow out through the plurality of air outlets 215 around the air outlet portion 2113, thereby increasing the air outlet area and further improving the humidification efficiency and humidification effect.

[0072] In some embodiments, the air outlet portion 2113 comprises a plurality of air guide bars, which are arranged at intervals along the circumference of the filter core 220, and one end of each air guide bar is connected with the first support shell 2112 and the other end is connected with the first air baffle 2111. Any two adjacent air guide bars form an air outlet 215. In this way, the air outlet area can be further increased, thereby improving the overall humidification efficiency and humidification effect of the humidifier 10.

[0073] In addition, as shown in Figures 2 to 4 , the air outlet 215 extends to the outer side wall of the filter core 220, thereby further increasing the air outlet area and reducing the air resistance. That is, the top end of the filter core 220 and the outer side wall near the top end of the filter core 220 are both effective air outlet areas of the filter core 220, so as to increase the air outlet area of the filter core 220 and improve the humidification efficiency.

[0074] In some embodiments, the first air baffle 2111, the air outlet portion 2113 and the first support shell 2112 are an integral structure, that is, the filter core upper cover 211 can be formed by an integral molding process such as injection molding or casting, thereby improving the compactness of the structure of the humidifier 10 and reducing the process steps, thereby reducing the process cost.

[0075] In some embodiments, as shown in Figure 2 , Figure 4 and Figure 5 , the filter core lower cover 212 further comprises a bearing portion 2123 between the second air baffle 2121 and the second support shell 2122. The bearing portion 2123 has a relief gap with the second support shell 2122. The filter core 220 is arranged on the bearing portion 2123, and the relief gap exposes part of the end surface of the filter core 220. The relief gap forms an air inlet 214. The relief gap can extend along the circumference of the filter core 220, thereby increasing the area of the air inlet 214 and improving the air volume entering the filter core 220. In addition, by arranging the filter core 220 on the bearing portion 2123, the strength and stability of the filter core 220 can be improved.

[0076] In some embodiments, as shown in Figure 2As shown, the second support shell 2122 is integrated with the main shell 110, and the main shell 110 is formed with the second support shell 2122 at one end close to the water tank 300, so that the compactness of the humidifier 10 is improved, and the integrity of the humidifier 10 is improved, the problem of the humidifier 10 being easily scattered when being tilted is avoided, and the installation process is reduced, and the process cost is reduced.

[0077] In addition, in order to prevent the problem that the excess water on the filter element 220 falls into the humidifier main machine 100 and causes damage to the internal components of the humidifier main machine 100, in the embodiment of the present application, please refer to Figures 2 to 4 As shown, the humidifier main machine 100 further comprises a water storage tray 130, which is arranged in the accommodation cavity and is sealingly connected with the cavity wall of the accommodation cavity, and the water storage tray 130 is located above the fan assembly 120; the water storage tray 130 has a water storage groove 131 and an air outlet grille 132 surrounding the outer circumferential side of the water storage groove 131, the air outlet grille 132 is arranged opposite to the air inlet 214, and the filter element 220 has a submerged part 221 at a position opposite to the water storage groove 131, that is, the excess water on the filter element 220 will drip along the submerged part 221, and the profile of the bearing part 2123 matches the submerged part 221, the bearing part 2123 is located in the water storage groove 131, and the bearing part 2123 has a through hole 2124 in communication with the water storage groove 131, so that the excess water on the filter element 220 can flow into the water storage groove 131 through the through hole 2124, thereby avoiding the excess water on the filter element 220 flowing into the humidifier main machine 100 through the air outlet grille 132, and improving the overall working and safety reliability of the humidifier 10; in addition, the air outlet grille 132 is arranged opposite to the air inlet 214, so that the airflow blown by the air outlet grille 132 directly enters the filter element 220 through the air inlet 214, so as to reduce the loss of airflow, thereby improving the humidification efficiency.

[0078] In addition, the water storage groove 131 further has a floating element, the floating element can float up and down with the change of the water level in the water storage groove 131, and the lower water hole of the water tank 300 is provided with a lower water valve, the lower water valve is connected with the floating element, so that the lower water valve can drive the lower water valve to move to open or close the lower water hole in the process of the floating element floating up and down.

[0079] Since the water tank 300 is arranged above the filter element assembly 200, the water tank 300 will block the air outlet 215, that is, the water tank 300 will produce a certain air resistance, which will affect the humidification efficiency of the humidifier 10, therefore, in the embodiment of the present application, please refer to Figure 1 and Figure 2As shown, the water tank 300 is formed with a wind guide structure 310 at the outer profile of the end close to the filter core assembly 200. The wind guide structure 310 and the air outlet 215 of the filter core assembly 200 form an air flow avoiding area. In this way, the air flow discharged from the air outlet 215 flows along the wind guide structure 310 to guide the air flow to the outside of the humidifier 10, so as to reduce the wind resistance generated by the water tank 300 and improve the humidifying efficiency and effect of the humidifier 10.

[0080] In the embodiments, the wind guide structure 310 can be connected between the bottom wall and the side wall of the water tank 300. For example, the wind guide structure 310 can be connected to the bottom wall of the water tank 300. Figure 1 In the embodiments, the wind guide structure 310 can be connected to the bottom wall of the water tank 300. Figure 2 In the embodiments, the wind guide structure 310 can be an arc-shaped wind guide surface, for example, a circular arc-shaped wind guide surface or an elliptical wind guide surface. The arc-shaped wind guide surface is curved towards the side of the filter core assembly 200, and the curvature is not limited as long as the wind resistance can be reduced.

[0081] In summary, in the humidifier provided by the embodiments, a separate air duct is arranged on the filter core support, and the filter core is arranged in the air duct. In this way, when the humidifier main machine is running, the air blown out of the air outlet directly enters the air duct through the air inlet on the filter core support. The air entering the air duct can effectively pass through the wet filter core, and then flow out of the air outlet, so as to reduce the air blown to the filter core flowing out of the non-air outlet area of the filter core, thereby improving the humidifying efficiency and effect of the humidifier.
