[0001] The present application relates to the technical field of household appliances, in particular to a humidifier. BACKGROUND

[0002] The fog-free humidifier is a kind of humidifier that can increase the humidity of air without generating visible water mist, which can reduce the deposition of water mist on furniture, reduce the breeding of bacteria, and avoid the potential damage of water mist deposition to furniture and floor.

[0003] In the related art, the fog-free humidifier includes a humidifier host, a filter element assembly, and a water tank. The filter element assembly is arranged between the humidifier host and the water tank. The water in the water tank is used to wet the filter element in the filter element assembly. The humidifier host has a motor and a fan connected to the motor. When the motor drives the fan to operate, the fan drives the airflow to flow so that the flowing airflow passes through the wet filter element in the filter element assembly and is discharged through the air outlet on the filter element assembly. In this way, the airflow discharged through the air outlet has a certain humidity, which can increase the humidity of the air, thereby achieving the purpose of humidifying the air.

[0004] However, in the related art, the humidifier has a large air outlet loss, which leads to low humidification efficiency and poor effect of the humidifier. CONTENT OF THE UTILITY MODEL

[0006] In order to achieve the above purpose, the embodiments of the present application provide the following technical solutions:

[0007] The embodiments of the present application provide a humidifier, which includes a filter element assembly and a water tank arranged above the filter element assembly. The filter element assembly includes a filter element and a filter element upper cover. The filter element upper cover is arranged at one end of the filter element facing the water tank. The filter element upper cover has a plurality of air outlets. The plurality of air outlets are arranged at intervals along the circumferential direction of the filter element, and the plurality of air outlets are located at the outer circumferential side of the connection position of the water tank and the filter element assembly.

[0008] The humidifier provided by the embodiments of the present application includes a filter element assembly and a water tank arranged above the filter element assembly. The filter element assembly includes a filter element and a filter element upper cover. The filter element upper cover is arranged at one end of the filter element facing the water tank. The filter element upper cover has a plurality of air outlets. The plurality of air outlets are arranged at intervals along the circumferential direction of the filter element, and the plurality of air outlets are located at the outer circumferential side of the connection position of the water tank and the filter element assembly. In this way, the airflow passing through the filter element flows out through the air outlets around, thereby reducing the wind resistance generated by the water tank, reducing the air outlet loss, and further improving the humidification efficiency and effect of the humidifier.

[0009] In some embodiments, an end surface of the upper cover of the filter core facing one end of the water tank forms an air outlet avoiding area between the bottom of the water tank and the outer contour of the side wall, so that the air flow discharged from the air outlet outlet passes through the air outlet avoiding area.

[0010] In this way, the air flow discharged from the air outlet outlet can pass through the air outlet avoiding area, further reducing the wind resistance generated by the water tank, thereby improving the humidification efficiency and effect of the humidifier.

[0016] In this way, the air flow discharged from the air outlet outlet is guided by the wind guide structure, reducing the wind resistance.

[0017] In some embodiments, the wind guide structure is an arc-shaped wind guide surface curved toward one side of the upper cover of the filter core.

[0018] In this way, the air flow discharged from the air outlet outlet can smoothly transition along the arc-shaped wind guide surface, further reducing the wind resistance.

[0019] In some embodiments, each of the air outlets extends to the side wall of the upper cover of the filter core, and the air outlets are configured to expose part of the side wall of the filter core.

[0022] In this way, the first wind blocking part blocks the wind, so that the airflow passing through the filter core flows along the height direction of the filter core, avoiding the airflow from flowing out from the circumference of the filter core, thereby reducing the loss of the airflow, improving the flow directionality of the airflow blowing to the filter core, and further improving the humidification efficiency and effect.

[0023] In some embodiments, the bottom of the water tank has a mounting protrusion matched with the first cylindrical structure, the mounting protrusion is configured to be clamped with the first cylindrical structure, and the air guide structure is arranged between the mounting protrusion and the side wall of the water tank.

[0024] In this way, the area of the water tank corresponding to the air outlet is the air guide structure, so that the airflow flowing out of the air outlet flows along the air guide structure, which can reduce the wind resistance generated by the water tank, thereby reducing the air outlet loss.

[0025] In some embodiments, the filter core assembly further comprises a filter core lower cover, the filter core lower cover has a second wind blocking part, the second wind blocking part is arranged below the first wind blocking part and connected with the first wind blocking part, the second wind blocking part forms a second cylindrical structure, the second cylindrical structure is matched with the first cylindrical structure, and the filter core is arranged on the outer circumferential side of the first wind blocking part and the second wind blocking part.

[0026] In this way, the first wind blocking part and the second wind blocking part jointly guide the airflow in the filter core, improve the flow directionality of the airflow blowing to the filter core, reduce the loss of the airflow, and thereby improve the efficiency of the humidifier.

[0029] In this way, the fan assembly drives the airflow to flow along the air inlet grille into the filter core and then out of the air outlet, forming an independent airflow flow channel, thereby reducing the loss of the airflow and improving the humidification efficiency; in addition, the water storage groove can collect the excess water on the filter core, avoiding the water from entering the humidifier main machine and affecting the overall performance of the humidifier, thereby improving the safety and reliability of the humidifier.

[0046] 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 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.

[0047] The embodiments of the present application provide a humidifier, which includes but is not limited to a mistless humidifier. The structure and working principle of the humidifier will be described in detail below by taking the mistless humidifier as an example.

[0048] In some embodiments, the humidifier includes a filter element assembly, a water tank, and a humidifier main body. The humidifier main body is arranged above the water tank, and the filter element assembly is arranged between the water tank and the humidifier main body. The humidifier main body has an air duct and a fan assembly located inside the air duct. The fan assembly includes a motor and a fan connected with the motor. When the motor is started, the fan can be driven to rotate so as to drive the air to flow. The top of the humidifier main body has an air outlet hole, and the side wall of the water tank has an air inlet hole. The water tank has a water pump for pumping the water in the water tank to the filter element assembly to wet the filter element in the filter element assembly. The filter element assembly has an air outlet near the center, which is in communication with the air inlet hole and the air duct in the humidifier main body. Thus, when the fan assembly operates, the air inlet hole, the air outlet, the air duct, and the air outlet hole form a channel for air flow. When the air flows through the filter element, the moisture on the filter element can evaporate naturally during the air flow and flow with 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 the breeding of bacteria, and avoiding the potential damage of water mist deposition to furniture and floor.

[0049] It can be understood that the water tank is used to store the humidification water of the humidifier. The humidification water in the water tank 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 humidifying the filter element will be collectively referred to as water, which will not be described in detail.

[0050] However, since the water pump is used to pump the water in the water tank to the top of the filter core, on the one hand, the water pump will generate noise when pumping water; on the other hand, the water pump arranged in the humidifier will cause the overall cost of the humidifier to be higher.

[0051] To solve the above problems, in some embodiments, as shown in Figure 1 The water tank 200 is arranged above the humidifier main machine 300, the filter core assembly 100 is arranged between the humidifier main machine 300 and the water tank 200, the bottom wall of the water tank 200 is provided with an openable and closable drain hole, and when the drain hole is opened after water is added to the water tank 200, the water in the water tank 200 drips and flows to the filter core 110 in the filter core assembly 100 to wet the filter core 110. Therefore, it is not necessary to additionally arrange a water pump to pump the water in the water tank 200 to the filter core assembly 100, which avoids the noise generated by the water pump when working, thereby improving the user experience; in addition, the problem of increasing the overall cost of the humidifier 10 due to the arrangement of the water pump is avoided, the cost is saved, and the economy of the humidifier 10 is improved.

[0052] The filter core assembly 100 generally includes the filter core 110, the filter core upper cover 120 and the filter core lower cover 130, the filter core upper cover 120 and the filter core lower cover 130 are oppositely arranged and connected to form a mounting cavity for mounting the filter core 110, the filter core 110 is mounted in the mounting cavity, the filter core lower cover 130 is provided with an air inlet, and the end face of the filter core upper cover 120 is provided with an air outlet 121, so that the airflow can be blown to the filter core 110 through the air inlet, and the airflow flowing through the filter core 110 can flow out through the air outlet 121. Since the filter core 110 is a wet filter core 110, the moisture on the filter core 110 can be naturally evaporated when the airflow passes through the filter core 110, and the airflow can flow into the air along with the airflow, so as to achieve the purpose of humidifying the air.

[0053] However, in the scheme of arranging the humidifier main machine 300 above the water tank 200, the air outlet 121 of the filter core assembly 100 is usually arranged at a position close to the middle of the filter core assembly 100 facing the humidifier main machine 300, so that the air outlet 121 is in communication with the air duct in the humidifier main machine 300. Therefore, if the water tank 200 is arranged above the filter core assembly 100 without redesigning the position of the air outlet 121 on the filter core upper cover 120, and only the positions of the water tank 200 and the humidifier main machine 300 are exchanged, the water tank 200 will block the air outlet 121 on the filter core upper cover 120, which limits the air outlet area of the air outlet 121, resulting in a large loss of the air outlet area, thereby affecting the humidification efficiency and effect of the humidifier 10.

[0054] In order to improve the humidification efficiency and effect of the humidifier 10 and improve the obstruction of the water tank 200 to the air outlet 121, in the embodiments of the present application, as shown in Figure 1 andFigure 2 As shown, the water tank 200 is arranged above the filter element assembly 100, and the humidifier main machine 300 is arranged below the water tank 200, so that the filter element assembly 100 is arranged between the humidifier main machine 300 and the water tank 200; the filter element upper cover 120 is arranged at one end of the filter element 110 facing the water tank 200, and the filter element upper cover 120 has a plurality of air outlets 121, which are arranged at intervals along the circumference of the filter element 110 and are located at the outer circumferential side of the connection position of the water tank 200 and the filter element assembly 100, that is, the plurality of air outlets 121 are arranged at the positions close to the edges of the four sides of the filter element upper cover 120, so that the air outlets 121 can avoid the obstacles caused by the water tank 200, and thus the airflow passing through the filter element 110 can flow out through the air outlets 121 on the four sides, thereby reducing the wind resistance caused by the water tank 200 and reducing the loss of the air outlet area, and further improving the humidification efficiency and effect of the humidifier 10.

[0055] It can be understood that the plurality of air outlets 121 are arranged close to the outer edges of the filter element upper cover 120, so that each air outlet 121 can avoid the water tank 200 and reduce the loss of the air outlet area caused by the water tank 200 blocking the air outlet 121, so as to avoid the bottom of the water tank 200 completely blocking the air outlet 121; in addition, the plurality of air outlets 121 are arranged at intervals along the circumference of the filter element upper cover 120, so that the air outlet area of the air outlet 121 can be increased, and the airflow passing through the filter element 110 can flow out through the air outlets 121 on the four sides, so as to improve the humidification efficiency of the humidifier 10.

[0056] In some embodiments, the plurality of air outlets 121 are uniformly arranged on the filter element upper cover 120 along the circumference, so that the air outlet uniformity of the humidifier 10 in the circumferential direction can be improved, so as to further improve the humidification efficiency and effect.

[0057] In order to further reduce the wind resistance, in the embodiments of the present application, please refer to Figures 2 to 5 As shown, each air outlet 121 extends to the side wall of the filter element upper cover 120, so that the air outlet 121 exposes part of the side wall of the filter element 110, so that part of the airflow can flow out through the outer side wall of the filter element 110 close to the water tank 200, and another part of the airflow flows out along the air outlet 121 on the top (as indicated by the arrow in Figure 2 , so as to increase the air outlet area of the air outlet 121 and reduce the air outlet resistance, thereby improving the humidification efficiency of the humidifier 10.

[0058] In some embodiments, please refer to Figures 2 to 5As shown, the filter core upper cover 120 comprises a first wind blocking portion 122, a grid air outlet portion 123 and a first support portion 124, the first wind blocking portion 122 is circumferentially formed into a first cylindrical structure, the filter core 110 is circumferentially arranged at the outer circumferential side of the first wind blocking portion 122, the first support portion 124 is circumferentially arranged at the outer circumferential side of the filter core 110, the grid air outlet portion 123 covers at least the end face of one end of the filter core 110 facing the water tank 200, and is connected with the first wind blocking portion 122 and the first support portion 124 respectively, the grid air outlet portion 123 has a plurality of air outlets 121, in this way, the first wind blocking portion 122 blocks the wind, so that the airflow passing through the filter core 110 flows along the height direction of the filter core 110, avoiding the airflow flowing out from the circumferential direction of the filter core 110, thereby reducing the loss of airflow, improving the flow guiding property of the airflow in the filter core 110, and further improving the humidification efficiency and effect.

[0059] Please continue to refer to Figures 2 to 5 As shown, the grid air outlet portion 123 comprises a plurality of air guide grid bars, the plurality of air guide grid bars are arranged at intervals along the circumferential direction of the filter core 110, one end of each air guide grid bar is connected with the first wind blocking portion 122, and the other end is connected with the first support portion 124, and the air outlet 121 is formed between any two adjacent air guide grid bars, in this way, the plurality of air outlets 121 are uniformly distributed along the circumferential direction of the filter core 110, so that the airflow can uniformly flow out along the circumferential direction of the filter core 110.

[0060] For example, in Figures 2 to 5 , the air guide grid bar has a first portion and a second portion, the first portion is arranged at the end of the end face of the filter core upper cover 120 facing the water tank 200, the second portion is connected with the first portion, and the second portion is bent towards the outer side wall of the filter core 110, in this way, the air outlet 121 formed between any two adjacent air guide grid bars extends to the outer side wall of the filter core 110, so that the airflow passing through the filter core 110 flows out through the top and part of the outer side wall of the filter core 110, the air outlet area is large, the wind resistance is small, and the humidification efficiency and effect of the humidifier 10 are further improved.

[0061] In order to further reduce the air outlet wind resistance, in some embodiments, please continue to refer to Figure 2 As shown, the end face of the end of the filter core upper cover 120 facing the water tank 200 and the outer contour of the bottom of the water tank 200 close to the side wall form an air outlet avoiding area 210, so that the airflow discharged from the air outlet 121 flows out through the air outlet avoiding area 210, in this way, the airflow flowing out through the air outlet 121 can flow out through the air outlet avoiding area 210, so as to further reduce the wind resistance generated by the water tank 200, thereby improving the humidification efficiency and effect of the humidifier 10.

[0062] It can be understood that the outer contour of the water tank 200 can be improved to form an air outlet avoiding area 210 between the filter core upper cover 120 and the water tank 200, wherein the air outlet avoiding area 210 refers to an area that can expose the air outlet 121 and does not hinder the air outlet 121, so that the airflow discharged by the air outlet 121 can flow out of the humidifier 10 through the air outlet avoiding area 210, and the wind resistance generated by the water tank 200 can be reduced, thereby improving the humidifying efficiency of the humidifier 10.

[0063] In some embodiments, please continue to refer to Figure 2 As shown, the bottom of the water tank 200 near the outer contour of the side wall has a wind guide structure 220, which is configured to guide the airflow discharged by the air outlet 121 to the outside of the humidifier 10, and the wind guide structure 220 forms an air outlet avoiding area 210 with the filter core upper cover 120, so that the airflow flowing out of the air outlet 121 can be guided by the wind guide structure 220 to reduce the wind resistance.

[0064] In addition, the air outlet avoiding area 210 completely exposes each air outlet 121 to further increase the air outlet area and reduce the air outlet resistance.

[0065] In some embodiments, as Figure 2 shown in the drawings, the wind guide structure 220 is an arc-shaped wind guide surface curved toward the filter core upper cover 120, for example, the arc-shaped wind guide surface can be a circular arc structure, as shown in Figure 2 The rounded corner of the bottom outer contour of the water tank 200 forms the wind guide structure 220, so that the airflow flowing out of the air outlet 121 can smoothly transition along the arc-shaped wind guide surface, further reducing the wind resistance.

[0066] As Figure 2 shown in the drawings, the wind guide structure 220 and the filter core upper cover 120 form an air outlet avoiding area 210 between the corresponding areas, that is, the contour shape of the wind guide structure 220 is improved to avoid and guide the airflow flowing out of the air outlet 121, so that the wind guide structure 220 and the air outlet 121 form an air outlet avoiding area 210 to reduce the air outlet resistance.

[0067] In some embodiments, the bottom of the water tank 200 near the middle has a mounting protrusion 230 matched with the first cylindrical structure, the mounting protrusion 230 is configured to be clamped with the first cylindrical structure, and the wind guide structure 220 is formed between the mounting protrusion 230 and the side wall of the water tank 200, so that the airflow flowing out of the air outlet 121 flows along the wind guide structure 220, which can reduce the wind resistance generated by the water tank 200, thereby reducing the air outlet loss.

[0068] In some embodiments, the cross-sectional area of the air-escape-avoiding area 210 gradually increases in a direction from the inside of the filter element 110 to the outside of the filter element 110, so that the distribution of the air flow discharged from the air outlet 121 can be optimized, and the air resistance can be reduced.

[0069] It should be noted that the plurality of air outlets 121 are arranged at intervals in the circumferential direction of the filter element 110, and therefore, the air-escape-avoiding area 210 extends in the circumferential direction of the filter element 110 to avoid the air flow flowing through each air outlet 121 and reduce the air resistance.

[0070] In some embodiments, as shown in Figs. 2 and 3, the filter element lower cover 130 has a second air blocking part 131 arranged below and connected with the first air blocking part 122, and the second air blocking part 131 surrounds to form a second cylindrical structure matched with the first cylindrical structure, and the filter element 110 is surrounded by the outer circumferential side of the first air blocking part 122 and the second air blocking part 131, so that the air flow in the filter element 110 is blocked and guided by the first air blocking part 122 and the second air blocking part 131 together, the air flow flowing along the inner side wall of the filter element 110 is avoided, the flow guiding property of the air flow blowing to the filter element 110 is improved, the air flow loss is reduced, and the efficiency of the humidifier 10 is improved.
