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

[0002] The fogless 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 also avoid the potential damage of water mist deposition to furniture and floor.

[0003] In the related art, the fogless humidifier includes a humidifier host, a filter element assembly, and a water tank. The filter element assembly is arranged between the water tank and the humidifier host. The water tank is used to store water for humidification. The water in the water tank flows to the filter element to achieve the purpose of wetting the filter element. In this way, when the humidifier is in humidification operation, the flowing air passes through the wet filter element, so that the water in the filter element can be naturally evaporated to increase the humidity of the air, thereby achieving the purpose of humidifying the air.

[0004] However, in the related art, there is a technical problem of low efficiency of wetting the filter element and poor humidity uniformity. CONTENT OF THE UTILITY MODEL

[0005] In view of the above problems, the embodiments of the present application provide a humidifier for improving the efficiency of wetting the filter element and the uniformity of the humidity of the filter element, thereby improving the humidification efficiency and humidification effect.

[0006] To achieve the above-mentioned purpose, the embodiments of the present application provide the following technical solutions:

[0007] The first aspect of the embodiments of the present application provides a filter element assembly, comprising: a filter element support, a filter element, and a water guide element. The filter element support has a liquid containing groove. The filter element is arranged around the outer periphery of the liquid containing groove.

[0008] One end of the water guide element is in communication with the liquid containing groove, and the other end of the water guide element extends in the filter element to guide the water in the liquid containing groove to the filter element through the water guide element.

[0009] In the filter element assembly provided by the embodiments of the present application, the water guide element is arranged. One end of the water guide element is in communication with the liquid containing groove, and the other end of the water guide element extends in the filter element. In this way, the water guide element can guide the water in the liquid containing groove to any position of the filter element, so as to improve the efficiency of wetting the filter element as a whole and the uniformity of the humidity of the filter element, thereby improving the humidification efficiency and humidification effect of the humidifier.

[0010] In some embodiments, one end of the water guide element penetrates through the groove side wall of the liquid containing groove near the bottom of the groove, and the other end of the water guide element extends along the height direction of the filter element towards the top of the filter element.

[0011] The water in the liquid tank is guided to the filter core by the water guide, and the water guide extends along the height direction of the filter core to the top of the filter core, so as to shorten the time of wetting the top of the filter core.

[0012] In some embodiments, the water guide has a water guiding part and a water guiding part, the water guiding part penetrates the tank side wall of the liquid tank and communicates with the liquid tank, the water guiding part is connected with the water outlet end of the water guiding part, the water guiding part is arranged in the filter core and extends along the height direction of the filter core to the top of the filter core, and the water guiding part is configured to guide the water discharged by the water outlet end of the water guiding part to the position close to the top of the filter core.

[0013] In this way, the water in the liquid tank is guided to the water guiding part in the filter core, so as to guide the water in the filter core to the top of the filter core by the water guiding part, and shorten the time of wetting the top of the filter core.

[0014] In some embodiments, the water guiding part further has an extension part at one end away from the water guiding part, and the extension part extends along the circumference of the filter core.

[0016] In some embodiments, the water guide further has a water accumulation tank, the water accumulation tank communicates with the water outlet end of the water guiding part, and the lower end of the water guiding part is arranged in the water accumulation tank.

[0017] In this way, the water guided by the water guiding pipe to the filter core is guided to the top of the filter core by the water guiding part, so as to accelerate the efficiency of wetting the top of the filter core, and avoid the problem of excessive water at the bottom of the filter core caused by the water flowing along the filter core to the bottom of the filter core.

[0018] In some embodiments, the water guiding part and the extension part are both water guiding cotton sticks.

[0019] In this way, the water guiding cotton stick has good water absorption, so that when the water guiding cotton stick absorbs water, the filter core in contact with the water guiding cotton stick can be wetted by the water absorbed by the water guiding cotton stick, without the need for other power components to pump water to the top of the filter core, thereby shortening the time of wetting the top of the filter core, and reducing the overall cost of the humidifier.

[0022] In some embodiments, when the water guide members are at least two and the liquid containing groove has multiple water outlets on the side wall thereof, the at least two water guide members and the at least two water outlets are arranged alternately and spaced apart along the circumference of the liquid containing groove.

[0023] In this way, the uniformity of the humidity of the filter element is improved, so that the humidifying effect is improved.

[0024] In some embodiments, the bottom of the liquid containing groove has a water outlet point and a drainage structure arranged around the water outlet point in the circumferential direction, and the drainage structure is configured to guide the liquid at the water outlet point to the circumference of the liquid containing groove.

[0025] In this way, the water dripping into the liquid containing groove is guided to the circumference of the liquid containing groove, so that the water in the liquid containing groove can quickly wet the filter element through the water guide members and the water outlets, thereby improving the efficiency of wetting the filter element.

[0027] The bottom of the water tank has an openable and closable water outlet hole, when the water outlet hole is opened, the water in the water tank drips and flows to the filter element in the filter element assembly through the water outlet hole.

[0028] The humidifier provided by the embodiments of the present application has the same beneficial effects as the filter element assembly provided by the above-mentioned embodiments, which will not be described here again; on the other hand, by arranging the water tank above the filter element assembly and arranging an openable and closable water outlet hole on the bottom wall of the water tank, when the water outlet hole is opened, the water in the water tank can drip and flow to the filter element assembly through the water outlet hole, without the need for additional pump or other water pumping device, thereby reducing the noise generated by the pump when pumping water during the operation of the humidifier, and avoiding the position of the humidifier where the cost of the humidifier is increased due to the pump or other water pumping device, thereby reducing the cost and improving the user experience.

[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 into the 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 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.

[0048] Referring to FIG. 1, Figure 1 The humidifier 10 provided by the embodiments of the present application includes a humidifier host 200, a filter element assembly 100, and a water tank 300. The water tank 300 is arranged above the humidifier host 200, and the filter element assembly 100 is arranged between the humidifier host 200 and the water tank 300. The water tank 300 is used to store water for humidification of the humidifier 10. The water for humidification 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 120 will be collectively referred to as water, which will not be described in detail.

[0049] In the embodiments of the present application, the water tank 300 is arranged above the filter element assembly 100, and a lower water hole that can be opened and closed is arranged. When the lower water hole is opened, the water in the water tank 300 can drip and flow to the filter element assembly 100 through the lower water hole, so as to achieve the purpose of wetting the filter element 120 with the water in the water tank 300 through the lower water hole. No additional pump or other water pumping device needs to be arranged, thereby reducing the noise generated by the pump when pumping water during the operation of the humidifier 10, and avoiding the position of the humidifier 10 where the cost is increased due to the pump or other water pumping device, thereby reducing the cost and improving the user experience.

[0050] In some embodiments, referring to FIG. 2, Figure 2As shown, the humidifier main machine 200 includes a main machine shell 210 and a fan assembly 220, the main machine shell 210 has a receiving cavity, the sidewall of the main machine shell 210 is provided with a plurality of air inlet holes 211 which are in communication with the receiving cavity, the plurality of air inlet holes 211 are arranged along the circumference of the main machine shell 210, so that external air can enter the inside of the receiving cavity through the air inlet holes 211, the fan assembly 220 is arranged in the receiving cavity, the fan assembly 220 includes a motor 221 and a fan 222, the fan 222 is connected with the motor 221, when the motor 221 is powered on and started, the motor 221 is used to drive the fan 222 to operate, so as to drive the air flow; the filter element assembly 100 is arranged above the fan assembly 220, the filter element assembly 100 includes a filter element support 110 and a filter element 120, the filter element 120 is installed on the filter element support 110, the filter element support 110 is used to provide a support basis for the filter element 120, wherein one end of the filter element support 110 facing the humidifier main machine 200 is provided with an air inlet 1121, the other end of the filter element support 110 is provided with an air outlet 1113, the water tank 300 is arranged above the filter element assembly 100, wherein the bottom wall of the water tank 300 is provided with a lower water hole which can be opened and closed, when the lower water hole is opened, the water in the water tank 300 drops through the lower water hole and flows to the filter element 120 in the filter element assembly 100, so as to wet the filter element 120, in this way, the flowing air flow blows to the filter element 120 through the air inlet 1121, the air flow passes through the wetted filter element 120, the moisture on the filter element 120 can evaporate naturally in the process of air flow and flow out through the air outlet 1113 with the air flow, so as to increase 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.

[0051] In some embodiments, referring to Figures 2 to 4 As shown, the filter element support 110 includes a filter element upper cover 111 and a filter element lower cover 112, the filter element 120 is arranged between the filter element upper cover 111 and the filter element lower cover 112, so as to provide a support basis for the filter element 120, wherein the filter element lower cover 112 is arranged at one end of the filter element 120 facing the humidifier main machine 200, the filter element upper cover 111 is arranged at the other end of the filter element 120 facing the water tank 300, wherein the filter element lower cover 112 is provided with the air inlet 1121, the filter element upper cover 111 is provided with the air outlet 1113; in addition, the filter element upper cover 111 and the filter element lower cover 112 jointly form an annular air duct, the filter element 120 is arranged in the annular air duct, by arranging an independent annular air duct, in this way, the air flow blowing to the filter element 120 can be gathered in the annular air duct, so as to avoid the air flow blowing to the filter element 120 flowing out through the circumferential sidewall (i.e. non-air outlet area) of the filter element 120, which causes the air flow blowing to the filter element 120 to not be able to effectively pass through the filter element 120 and flow out through the air outlet 1113, thereby affecting the humidification efficiency and effect of the humidifier 10.

[0052] It can be understood that the filter core 120 is annular, and the filter core upper cover 111 and the filter core lower cover 112 are respectively provided with the wind blocking part on the inner side wall and the outer side wall of the filter core 120. In this way, the annular air duct is formed between the wind blocking parts arranged on the inner side wall and the outer side wall of the filter core 120, so as to gather the airflow blown to the filter core 120, so that the airflow can effectively pass through the entire filter core 120 after being wetted, and then flow out through the air outlet 1113, so as to improve the humidification efficiency of the humidifier 10.

[0053] Please refer to Figure 2 It can be understood that the filter core 120 is annular, and the filter core upper cover 111 and the filter core lower cover 112 are respectively provided with the wind blocking part on the inner side wall and the outer side wall of the filter core 120. In this way, the annular air duct is formed between the wind blocking parts arranged on the inner side wall and the outer side wall of the filter core 120, so as to gather the airflow blown to the filter core 120, so that the airflow can effectively pass through the entire filter core 120 after being wetted, and then flow out through the air outlet 1113, so as to improve the humidification efficiency of the humidifier 10.

[0054] In addition, since the water tank 300 is arranged on the top of the filter core assembly 100, wind resistance is generated, which affects the air outlet area and the air outlet efficiency of the air outlet 1113. Therefore, in the embodiment of the present application, please refer to Figure 1 and Figure 2 It can be understood that the filter core 120 is annular, and the filter core upper cover 111 and the filter core lower cover 112 are respectively provided with the wind blocking part on the inner side wall and the outer side wall of the filter core 120. In this way, the annular air duct is formed between the wind blocking parts arranged on the inner side wall and the outer side wall of the filter core 120, so as to gather the airflow blown to the filter core 120, so that the airflow can effectively pass through the entire filter core 120 after being wetted, and then flow out through the air outlet 1113, so as to improve the humidification efficiency of the humidifier 10.

[0055] For example, in Figure 1 and Figure 2 The air deflection structure 310 is an arc-shaped air deflection surface. The air deflection structure 310 is arranged at the transition position between the bottom wall and the outer side wall of the water tank 300, that is, the air deflection structure 310 is an arc-shaped chamfer arranged between the bottom wall and the outer side wall of the water tank 300. The arc-shaped chamfer forms the air deflection structure 310, so as to reduce the wind resistance generated by the water tank 300 through the air deflection structure 310, and avoid the air outlet position of the air outlet 1113 through the air deflection structure 310 to increase the effective air outlet area, thereby improving the humidification efficiency of the humidifier 10.

[0056] In addition, it can be understood that the larger the wetted area of the filter core 120 and the effective area of the filter core 120 through which the airflow blown to the filter core 120 passes, the better the humidification effect.

[0057] In some embodiments, please refer to Figure 2 and Figure 3As shown, the filter holder 110 has a liquid pool 1111 located below the water outlet of the water tank 300, the filter 120 is arranged around the outer periphery of the liquid pool 1111, the liquid pool 1111 has a plurality of water outlets 1112 on the pool wall, and the plurality of water outlets 1112 are arranged in a circumferential direction of the liquid pool 1111. In this way, the water in the water tank 300 drips into the liquid pool 1111 through the water outlet, and the water in the liquid pool 1111 flows to the filter 120 through the water outlets 1112 around the liquid pool 1111, so as to wet the filter 120 along the circumferential direction of the filter 120, thereby improving the efficiency of wetting the filter 120 and the uniformity of the humidity of the filter 120.

[0058] Please continue to refer to Figure 2 and Figure 3 As shown, in the vertical direction (i.e. the height direction of the filter 120), the depth of the liquid pool 1111 is about 1 / 2 of the height of the filter 120, and the water outlets 1112 are usually arranged at a position close to the bottom wall of the liquid pool 1111. In this way, as long as there is water in the liquid pool 1111, it can flow to the filter 120 through the water outlets 1112, so that the water dripping into the liquid pool 1111 can flow to the filter 120 in time, thereby shortening the time of wetting the filter 120.

[0059] Therefore, in Figure 2 and Figure 3 , the water enters the filter 120 from about 1 / 2 of the height of the filter 120. In this way, when there is enough water flowing to the lower part of the filter 120, the lower water will wet the material of the upper half of the filter 120, which will result in a longer time of wetting the upper half of the filter 120 and a relatively lower humidity after wetting, i.e. the humidity of the upper half of the filter 120 structure is insufficient, thereby affecting the humidification efficiency of the humidifier 10.

[0060] In order to shorten the time required for wetting the upper half of the filter 120, in the embodiments of the present application, please refer to Figure 2 and Figure 3 As shown, the filter assembly 100 further comprises a water guide 130, one end of the water guide 130 is in communication with the liquid pool 1111, and the other end extends into the filter 120. In this way, the water guide 130 can guide the water in the liquid pool 1111 to any position to be wetted in the filter 120, for example, the time required for wetting the upper half of the filter can be shortened, thereby accelerating the efficiency of wetting the filter 120 and the uniformity of the humidity of the filter 120, thereby improving the humidification efficiency and effect.

[0061] It can be understood that one end of the water guide 130 is in communication with the liquid containing groove 1111, and the other end can extend in any direction in the filter core 120, as long as it can accelerate the efficiency of wetting the filter core 120 and improve the uniformity of the humidity of the filter core 120; for example, the water guide 130 can extend from top to bottom in the height direction of the filter core in the filter core 120; or the water guide 130 can extend from bottom to top in the filter core; or the other end of the water guide 130 enters the filter core 120 from the position close to the middle of the filter core 120, and extends upward and downward from the position close to the middle of the filter core 120; or the water guide 130 can extend in the filter core 120 in addition to at least one of the upward and downward directions in the height direction of the filter core 120, and can also extend in the circumferential direction of the filter core 120 or any other direction, and the water guide 130 can also extend in the filter core 120 in the height direction of the filter core 120 from bottom to top or from top to bottom. In short, as long as the purpose of quickly wetting the filter core 120 and improving the humidity of the filter core 120 can be achieved, it is not limited here.

[0062] It should be noted that in the embodiments of the present application, the scheme of wetting the filter core 120 by the water guide 130 is not limited to the water tank 300 being arranged above the humidifier main machine 200, but is also applicable to the water tank 300 being arranged below the humidifier main machine 200 or any other position. In the embodiments of the present application, the water tank 300 is arranged above the humidifier main machine 200 as an example.

[0063] In some embodiments, in addition to arranging the water guide 130, a plurality of water outlets 1112 are also arranged on the groove wall of the liquid containing groove 1111, so as to wet the filter core 120 through the water guide 130 and the plurality of water outlets, so as to further improve the efficiency of wetting the filter core 120.

[0064] In specific implementation, when the humidifier 10 is started to work, the lower water hole of the water tank 300 is opened, so that the water in the lower water hole drops into the liquid containing groove 1111. On the one hand, the water dropped into the liquid containing groove 1111 can flow to the filter core 120 through the circumferential water outlets 1112 to wet the filter core 120; on the other hand, the water in the liquid containing groove 1111 is guided to the upper half of the filter core 120 through the water guide 130, thereby shortening the time for wetting the top of the filter core 120 and improving the efficiency of wetting the whole filter core 120, thereby improving the humidification efficiency and humidification effect of the humidifier 10.

[0065] An exemplary water guide 130 can be a water guide cotton stick, one end of which is located in the liquid tank 1111 and the other end of which extends into the filter element 120 and extends to the upper half of the filter element 120, so that after the water guide cotton stick contacts the water in the liquid tank 1111, the water guide cotton stick absorbs water and then contacts the filter element 120, the water on the water guide cotton stick can wet the filter element 120 in contact with it, thereby accelerating the wetting of the upper half of the filter element 120 and shortening the time required for the upper half of the filter element 120 to be wetted. Wherein the water guide cotton stick can be directly in contact with the top of the filter element 120 and extend downward along the filter element 120; or the water guide cotton stick can also extend in the filter element 120 towards the top of the filter element 120; or the water guide cotton stick can extend in a spiral shape along the circumference of the upper half of the filter element 120, so as to increase the contact area between the water guide cotton stick and the filter element 120, so that the water guide cotton stick after absorbing water can quickly wet the upper half of the filter element 120, thereby shortening the time for the upper half of the filter element 120 to be wetted.

[0066] Another exemplary water guide 130 can also be a drainage tube or the like to directly guide water to the upper half of the filter element 120, as long as it can accelerate the wetting of the upper half of the filter element 120, which is not limited here.

[0067] In some embodiments, please refer to Figure 2 and Figure 3 for example, the water guide 130 includes a water guide cotton stick, one end of the water guide 130 penetrates the tank side wall of the liquid tank 1111 near the bottom end of the tank, so as to facilitate the water guide 130 to contact the water in the liquid tank 1111, and the other end of the water guide 130 extends along the height direction of the filter element 120 towards the top of the filter element 120, so that the water guide cotton stick can absorb sufficient water to wet the upper half of the filter element 120 in the vertical direction, without the need for additional mechanism to suck water to the top of the filter element 120, while achieving the acceleration of wetting the upper half of the filter element 120, the structure is simple and the cost is low.

[0068] In order to further improve the efficiency of wetting the upper half of the filter element 120, in the embodiments of the present application, please refer to Figures 2 to 5As shown, the water guide 130 has a water guide part 131 and a water guide part 132, the water guide part 131 penetrates the tank side wall of the liquid containing tank 1111 and communicates with the liquid containing tank 1111, the water guide part 132 is connected with the water outlet end of the water guide part 131, the water guide part 132 is arranged in the filter core 120 and extends along the height direction of the filter core 120 to the top of the filter core 120, the water guide part 132 is configured to guide the water discharged from the water outlet end of the water guide part 131 to the position close to the top of the filter core 120, so as to guide the water in the liquid containing tank 1111 to the water guide part 132 in the filter core 120, so as to guide the water to the top of the filter core 120 by the water guide part 132, so as to shorten the time of wetting the top of the filter core 120; and the water guided into the filter core 120 and not absorbed by the water absorbing part can continuously wet the lower half of the filter core 120, when the lower half of the filter core 120 is full of water, it will continue to wet the upper part of the filter core 120, thereby further improving the efficiency of wetting the overall structure of the filter core 120.

[0069] For example, the water guide part 132 is a water guide cotton stick, and the water guide part 131 is a water guide pipe capable of quickly guiding the water in the liquid containing tank 1111 to one end of the water guide part 132, so as to accelerate the water absorption of the water guide part 132, thereby wetting the filter core 120 through the water guide part 132.

[0070] The water guide part 131 can be a water guide pipe, or a water guide groove or a water guide channel extending from the bottom wall of the liquid containing tank 1111 to the filter core 120, so as to quickly guide the water in the liquid containing tank 1111 to the water guide part 132 through the water guide groove or the water guide channel.

[0071] In the following, the water guide part 131 is taken as an example of a water guide pipe, that is, the water in the liquid containing tank 1111 is guided to the water guide part 132 through the water guide pipe, so that the water guide pipe can be arranged according to specific needs, and the water can be guided to a position close to the inside of the filter core 120 or any other area.

[0072] In order to accelerate the water absorption efficiency of the water absorbing part, in the embodiment of the present application, please refer to Figures 2 to 5 As shown, the water guide 130 also has a water accumulation groove 133, the water accumulation groove 133 communicates with the water outlet end of the water guide pipe, and the lower end of the water guide part 132 is arranged in the water accumulation groove 133, so that the water in the liquid containing tank 1111 can be quickly guided into the water accumulation groove 133 through the water guide pipe, and one end of the water guide part 132 is arranged in the water accumulation groove 133, so as to quickly absorb the water in the water accumulation groove 133, so that the water absorbing part has enough water to wet the filter core 120, thereby accelerating the problem of wetting the upper half of the filter core 120.

[0073] It can be understood that when the water in the water accumulation groove 133 is too much to cause overflow, the water overflowing from the water accumulation groove 133 can continuously wet the lower half of the filter core 120.

[0074] In some embodiments, the water guide 132 further has an extension (not shown in the figure) away from one end of the guide tube, the extension extending along the circumference of the filter core 120 to further shorten the time for wetting the top of the filter core 120 and improve the efficiency of wetting the filter core 120 by the extension extending along the circumference of the filter core 120.

[0075] In some embodiments, the water guide 132 and the extension are both water guide cotton sticks, and it can be understood that the water guide cotton sticks have good water absorption, so that when the water guide cotton sticks absorb water, the filter core 120 in contact with the water guide cotton sticks can be wetted by the water absorbed by the water guide cotton sticks, without the need for other power components to pump water to the top of the filter core 120, thereby shortening the time for wetting the top of the filter core 120 and reducing the overall cost of the humidifier 10.

[0076] In order to improve the uniformity of the wetting of the filter core 120, in the embodiments of the present application, please refer to Figures 2 to 4 As shown in the figure, the water guide 130 is at least two, and the at least two water guides 130 are arranged at intervals along the circumference of the filter core 120 to wet the upper half of the filter core 120 by the at least two water guides 130, thereby further improving the efficiency of wetting the filter core 120 and the uniformity of the humidity of the filter core 120.

[0077] In some embodiments, the at least two water guides 130 and the at least two water outlets 1112 are arranged alternately and at intervals along the circumference of the liquid containing groove 1111, so that the uniformity of the humidity of the filter core 120 in the circumferential direction can be further improved, thereby improving the humidifying effect.

[0078] In order to improve the entry of the water in the liquid containing groove 1111 into the filter core 120 through the water outlets 1112 and the water guides 130, in the embodiments of the present application, please refer to Figure 2 and Figure 3 As shown in the figures, the bottom of the liquid containing groove 1111 has a water outlet point (not shown in the figure) and a drainage structure 1114 arranged circumferentially around the water outlet point, and it can be understood that the water outlet point is a region corresponding to the water outlet hole on the water tank 300, that is, when the water outlet hole is opened, the dropping point in the liquid containing groove 1111 corresponds to the region where the water drops, and the drainage structure 1114 is configured to drain the liquid at the water outlet point to the four sides of the liquid containing groove 1111 to facilitate the drainage of the water dropped into the liquid containing groove 1111 to the four sides of the liquid containing groove 1111, so that the water in the liquid containing groove 1111 can quickly wet the filter core 120 through the water guides 130 and the water outlets 1112, thereby improving the efficiency of wetting the filter core 120.

[0079] For example, as shown in Figure 2 and Figure 3As shown in the figure, the inner bottom wall of the liquid holding groove 1111 has a conical protrusion extending upward, and the conical surface of the conical protrusion is formed as a flow guide structure 1114, so that the water dripping to the water outlet point can be guided to the periphery of the liquid holding groove 1111, so that the water can quickly enter the filter core 120 through the water outlet 1112 and the flow guide part 131.

[0080] In some embodiments, the humidifier main machine 200 further comprises a water storage tray 230, which is arranged in the accommodation cavity and above the fan assembly 220. The water storage tray 230 has a water storage groove 231. The filter core 120 has a submerged part. The structure corresponding to the submerged part of the lower cover 112 of the filter core matches the submerged part. The structure corresponding to the submerged part of the lower cover 112 of the filter core and the submerged part are located in the water storage groove 231. The lower cover 112 of the filter core has a through hole, so that the excess water on the filter core 120 can flow into the water storage groove 231, thereby avoiding the problem that the excess water on the filter core 120 drips into the humidifier main machine 200, causing damage to the internal components of the humidifier main machine 200.

[0081] In addition, the water storage tray 230 also has an air outlet grille 232, which is arranged around the outer periphery of the water storage groove 231 and is arranged opposite to the air inlet 1121 on the lower cover 112 of the filter core. In this way, the air blown by the fan assembly 220 is directly blown to the filter core 120 through the air outlet grille 232 and the air inlet 1121, so as to reduce the loss of air.

[0082] In some embodiments, the water outlet hole of the water tank 300 has a valve body mechanism 250 for closing or opening the water outlet hole. The valve body mechanism 250 can be manually opened or closed by the user, or the movement of the valve body mechanism 250 can be driven by a driving mechanism to achieve the opening and closing of the water outlet hole.

[0083] In some embodiments, the humidifier 10 further comprises a floating member 240 arranged in the water storage groove 231. The floating member 240 includes but is not limited to a floating bottle or a floating block, and the floating member 240 can float up and down with the change of the water level in the water storage groove 231. The floating member 240 is connected with the valve body mechanism 250, and the valve body mechanism 250 can open or close the water outlet hole when the floating member 240 floats up and down.

[0084] For example, when the water level in the water storage groove 231 rises to a certain height, the floating member 240 drives the valve body mechanism 250 to move, so that the valve body mechanism 250 closes the water outlet hole to prevent the water outlet hole from continuing to drain water and causing the water storage groove 231 to overflow. When the water level in the water storage groove 231 drops to a certain height, the floating member 240 drives the valve body mechanism 250 to move, so that the valve body mechanism 250 opens the water outlet hole.

[0085] In some embodiments, the valve body mechanism 250 comprises a valve rod, a sealing member and a connecting rod, the valve rod is arranged in the drain hole, the sealing member is sleeved on the top end of the valve body, and the connecting rod is connected between the valve rod and the floating member 240, that is, one end of the connecting rod is connected with the valve rod, and the other end of the connecting rod is connected with the floating member 240, the side wall of the connecting rod rotates relative to the fixed axis, so that the two ends of the connecting rod rotate around the fixed axis, and the movement directions of the two ends of the connecting rod are opposite, for example, when the floating member 240 floats upward, the floating member 240 drives the valve rod to move downward through the connecting rod, when the water level in the water storage tank 231 rises to a certain height, the sealing member seals the drain hole; when the water level in the water storage tank 231 drops, the floating member 240 drives the valve rod to move upward through the connecting rod, so that the sealing member gradually moves away from the drain hole, and when the water level in the water storage tank 231 drops to a certain height, the sealing member unseals the drain hole to open the drain hole.

[0086] In summary, in the humidifier provided by the embodiment of the present application, the water guide member is arranged, one end of the water guide member is located in the liquid containing tank, and the other end of the water guide member extends in the filter element, so that the water in the liquid containing tank is guided to any position of the filter element through the water guide member, the efficiency of wetting the filter element is accelerated, the uniformity of the humidity of the filter element is improved, and the humidifying efficiency and humidifying effect of the humidifier are improved.
