[0005] In view of the above problems, an embodiment of the present application provides a humidifier that can improve the uniformity of the water content of the filter element, thereby improving the humidification effect of the humidifier.

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

[0007] The embodiment of the present application provides a humidifier, comprising: a water tank, a filter element bracket and a filter element assembly, wherein the filter element bracket is located in the water tank, and the filter element assembly is arranged on the filter element bracket;

However, in the related art, water flowing out of the water outlet directly enters the leakage holes along the circumference of the filter element upper cover to wet the filter element under the filter element upper cover. In this way, the closer to the water outlet, the greater the leakage, resulting in different degrees of wetting at different circumferential positions of the filter element and different water contents at different positions of the filter element, leading to a technical problem of relatively low effective use area of ​​the filter element.

[0050] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0052] An embodiment of the present application provides a humidifier, which includes but is not limited to a fogless humidifier. The humidifier will be introduced below by taking the fogless humidifier as an example.

[0053] Please refer to Figure 1 As shown, the humidifier 100 provided in the embodiment of the present application includes a water tank 110 and a humidifier host 160; the humidifier host 160 can be arranged on the water tank 110, that is, the water tank 110 provides a supporting base for the humidifier host 160; the water tank 110 has a accommodating cavity, and the water tank 110 is used to hold the humidification water of the humidifier 100. An air inlet 111 is arranged on the side wall of the water tank 110, and the air inlet 111 can be arranged at a position near the top of the water tank 110, so that it can be ensured that the water tank 110 can have a certain water holding capacity.

[0054] Among them, the humidification water contained in the water tank 110 can be pure water, or it can be an aqueous solution with additives such as mixed spices, fungicides, essential oils, etc. The embodiment of the present application does not make specific limitations on this. The liquid in the water tank 110 is generally referred to as water below and no specific explanation is given.

[0055] Please refer to Figures 2 to 4As shown, in some embodiments, the humidifier 100 further includes a filter element support 120, a filter element assembly 130, a water pump 140, a water pump support 141 and a water outlet pipe 150, the filter element support 120 and the water pump support 141 are both disposed in the water tank 110, and the filter element assembly 130 is disposed on the filter element support 120 (such as Figure 2 ), in this way, the filter element assembly 130 can be kept at a certain height from the water surface in the water tank 110 to prevent the filter element assembly 130 from being immersed in water; the water pump 140 is arranged on the water pump bracket 141, and the water pump bracket 141 can be connected to the filter element bracket 120 by screws or other threaded connectors, and the water pump bracket 141 is used to support the water pump 140, in this way, it can be avoided that the water pump 140 is arranged on the bottom wall of the water tank 110, which causes the water pump 140 to suck the foreign particles deposited on the bottom of the water tank 110 into the water pump 140 and affect the life of the water pump 140; the water outlet pipe 150 is connected to the water outlet end of the water pump 140, and the water pump 140 is used to pump water out of the water tank 110, wherein the water outlet pipe 150 is, for example, a water outlet hose, so that it can be bent arbitrarily according to specific needs, thereby improving the user experience.

[0056] Please refer to Figure 4 As shown, in some embodiments, the filter element assembly 130 includes a filter element 131, a filter element upper cover 132, a filter element lower cover 133 and a water diversion pipe 134, the filter element 131 is clamped between the filter element upper cover 132 and the filter element lower cover 133, for example, the two ends of the filter element 131 are respectively fixed by bonding or the like; wherein, a water outlet 1321 and a plurality of water leakage holes 1322 are provided on the filter element upper cover 132, the water diversion pipe 134 is penetrated through the filter element upper cover 132 and the filter element lower cover 133, and one end of the water diversion pipe 134 is connected to the water outlet 1321, and the other end of the water diversion pipe 134 is connected to the water outlet pipe 150, so that the water pump 140 can pump water in the water tank 110 to the filter element upper cover 132, and the water flows to the filter element 131 from the water leakage holes 1322 on the filter element upper cover 132 to humidify the filter element 131.

[0057] In addition, please continue to refer to Figure 2 and Figure 4As shown, the filter element assembly 130 also includes a first elastic bracket 135 and a second elastic bracket 136. The first elastic bracket 135 is arranged on the filter element lower cover 133, the second elastic bracket 136 is arranged on the filter element upper cover 132, and the water outlet 1321 is arranged on the second elastic bracket 136. In this way, one end of the water diversion pipe 134 is clamped on the first elastic bracket 135 and connected with the water outlet pipe 150, and the other end of the water diversion pipe 134 is clamped on the second elastic bracket 136 and connected with the water outlet 1321, so that the water diversion pipe 134 is fixed to the filter element upper cover 132 and the filter element lower cover 133 through the first elastic bracket 135 and the second elastic bracket 136, so as to realize the limitation and fixation of the water diversion pipe 134, thereby improving the simplicity and reliability of the water diversion pipe 134.

[0058] Exemplarily, the first elastic bracket 135 can be a first silicone bracket, the second elastic bracket 136 can be a second silicone bracket, and the filter element lower cover 133 and the filter element upper cover 132 are respectively provided with mounting holes 1326, so that the first silicone bracket can be arranged in the mounting hole 1326 of the filter element lower cover 133 by interference fit, and the second silicone bracket is arranged in the case hole of the filter element upper cover 132 by interference fit, and the first silicone bracket and the second silicone bracket are respectively provided with through holes for the water diversion pipe 134 to pass through. In this way, the two ends of the water diversion pipe 134 are respectively interference-connected with the through holes on the first silicone bracket and the second silicone bracket, thereby simplifying the installation process of the water diversion pipe 134, the first silicone bracket and the second silicone bracket with the filter element lower cover 133 and the filter element upper cover 132, thereby reducing the installation cost; in addition, the second silicone bracket is provided with a water outlet 1321 connected to the water diversion pipe 134, so that the water pump 140 pumps the water in the water tank 110 to the filter element upper cover 132, and finally wets the filter element 131 below through the leakage holes 1322.

[0059] Also, please refer to Figure 5 As shown, the humidifier host 160 includes a lower shell 161 and an upper shell 162, and the lower shell 161 and the upper shell 162 are fixedly connected, for example, by screws, wherein the lower shell 161 is provided with an air duct connected to the accommodating cavity of the water tank 110, the air duct is provided with a motor 165 and a wind wheel 164, and the upper shell 162 is provided with an air outlet 1621 connected to the air duct. It can be understood that the motor 165 provides electrical energy to the wind wheel 164, so that the wind wheel 164 rotates to provide power to the flow of the airflow, thereby humidifying the fluidity of the airflow, so that the fluidity of the airflow in the humidifier 100 can be improved.

[0060] In a specific implementation, the motor 165 drives the wind wheel 164 to rotate. After the external airflow enters the containing cavity of the water tank 110 through the air inlet 111 on the side wall of the water tank 110, the airflow entering the water tank 110 passes through the filter element 131 and is discharged to the outside air from the air outlet 1621 through the air duct. The rotation of the wind wheel 164 can increase the flow rate of the airflow. During the flow, the airflow can carry away the water molecules on the filter element 131, so that the airflow discharged from the humidifier 100 contains a certain amount of water molecules, thereby increasing the humidity of the air and achieving the purpose of air humidification.

[0061] In some embodiments, the humidifier host 160 may further include an air guide shell 163, which may be installed on the upper shell 162 by, for example, a detachable connection, and an air guide port is provided on the air guide shell 163, which is connected to the air outlet 1621 on the upper shell 162, so that the airflow discharged from the air outlet 1621 can be guided according to the needs of the user through the air guide port, thereby improving the user's experience.

[0062] In some embodiments, in order to increase the humidification area of ​​the filter element 131, the filter element 131 is formed into a rotating structure. For example, the filter element 131 is formed into a cylindrical structure (such as Figure 4 As shown in ), in this way, both the filter element upper cover 132 and the filter element lower cover 133 will have a rotating structure. For example, the filter element upper cover 132 and the filter element lower cover 133 are annular structures. The multiple water leakage holes 1322 on the filter element upper cover 132 are arranged at intervals along the circumference of the filter element upper cover 132. After the water pumped out by the water pump 140 is discharged from the water outlet 1321, the water will directly enter the filter element 131 through the water leakage holes 1322 along the circumference of the filter element upper cover 132, so as to wet the filter element 131 located below the filter element upper cover 132, so as to achieve the purpose of humidifying the filter element 131.

[0063] However, during the humidification process of the filter element 131, the amount of water leaking from the leaking port on the side close to the water outlet 1321 to the filter element 131 is greater than the amount of water leaking from the leaking port on the side far from the water outlet 1321 to the filter element 131. This results in different degrees of wetting of the filter element 131 in the circumferential direction, and differences in the water content of the filter element 131 in the circumferential direction. Therefore, when the humidifier 100 is in the humidification process, part of the area of ​​the filter element 131 has insufficient water content, resulting in a reduction in the molecular weight of water carried by the humidified airflow, and the effective humidification area of ​​the filter element 131 is relatively low, thereby affecting the humidification effect of the humidifier 100.

[0064] In order to improve the humidification effect of the humidifier 100 and improve the problem of uneven water content in the circumferential direction of the filter element 131, in the embodiment of the present application, a water diversion structure is provided on the filter element upper cover 132, and the water diversion structure includes a plurality of water leakage holes 1322, and the plurality of water leakage holes 1322 and the water outlet 1321 are arranged at intervals along the circumference of the filter element upper cover 132, and the water leakage difficulty of the water leakage hole 1322 close to the water outlet 1321 is greater than the water leakage difficulty of the water leakage hole 1322 far from the water outlet 1321. That is to say, the water leakage amounts of the leakage holes 1322 on the filter element upper cover 132 that are connected to the filter element 131 toward the filter element 131 are different. By making the water leakage difficulty of each leakage hole 1322 toward the filter element 131 different, the water leakage amounts of each leakage hole 1322 toward the filter element 131 are made to be nearly the same, thereby improving the uniformity of the water content in the circumferential direction of the filter element 131, so as to ensure the content of water molecules in the humidified airflow of the humidifier 100, thereby improving the humidification effect of the humidifier 100.

[0065] Please refer to Figure 6 and Figure 7 As shown, in some embodiments, a water diversion groove 1323 is provided on the filter element upper cover 132, and the water diversion groove 1323 extends along the circumference of the filter element upper cover 132. For example, the water diversion groove 1323 is formed as a circular annular groove, and the water diversion groove 1323 is respectively connected to the water outlet 1321 and multiple leakage holes 1322, and a water retaining platform 1324 is provided between the water diversion groove 1323 and each leakage hole 1322. Along the circumference of the filter element upper cover 132, the height of the water retaining platform 1324 close to the water outlet 1321 is greater than the height of the water retaining platform 1324 away from the water outlet 1321.

[0066] It should be noted that the water retaining platform 1324 is completely blocked between the water diversion groove 1323 and the water leakage hole 1322. In this way, the water inflow amount of the water in the water diversion groove 1323 into the water leakage hole 1322 is limited by the height of the water retaining platform 1324. The higher the height of the water retaining platform 1324, the more difficult it is for the water in the water diversion groove 1323 to enter the water leakage hole 1322, and the lower the height of the water retaining platform 1324, the less difficult it is for the water in the water diversion groove 1323 to enter the water leakage hole 1322. Therefore, by setting water retaining platforms 1324 of different heights between the water diversion groove 1323 and each water leakage hole 1322, 24, so that the difficulty of water leakage from different leakage holes 1322 to the filter element 131 is different, so that the amount of water leakage from each leakage hole 1322 to the filter element 131 is basically the same, so that the water content of the filter element 131 in the circumferential direction remains basically consistent, so as to improve the uniformity of the water content of the filter element 131 in the circumferential direction. In this way, the airflow enters the water tank 110 through the air inlet 111 at different circumferential positions of the water tank 110, and the water molecules carried by the airflow after passing through different circumferential positions of the filter element 131 remain basically consistent, thereby ensuring the humidification effect of the humidifier 100 and the humidification amount of the humidifier 100.

[0067] Among them, since the water inlet amount of the leakage hole 1322 near the water outlet 1321 is greater than the water inlet amount of the leakage hole 1322 far away from the water outlet 1321, the height of the water retaining platform 1324 near the water outlet 1321 is greater than the height of the water retaining platform 1324 far away from the water outlet 1321, so as to ensure that the water inlet amount of the leakage hole 1322 near the water outlet 1321 is basically the same as the water inlet amount of the leakage hole 1322 far away from the water outlet 1321.

[0068] It can be seen that in the embodiment of the present application, a water diversion groove 1323 is provided on the filter element upper cover 132, so that the water flowing out of the water outlet 1321 flows along the extension direction of the water diversion groove 1323, and when the water level in the water diversion groove 1323 is higher than the height of the water retaining platform 1324 corresponding to each leakage hole 1322, the water in the water diversion groove 1323 passes over the water retaining platform 1324 and leaks to the filter element 131 below through the leakage hole 1322 to wet the filter element 131; in addition, since the height of the water retaining platform 1324 corresponding to each leakage hole 1322 is different, the leakage difficulty of each leakage hole 1322 can be adjusted according to the height of the water retaining platform 1324, thereby controlling the leakage amount of each leakage hole 1322, so that the leakage amount of each leakage hole 1322 on the filter element upper cover 132 is basically consistent, thereby improving the uniformity of the water content of the filter element 131 in the circumferential direction, and further improving the humidification effect of the humidifier 100.

[0069] Since the leakage holes 1322 are arranged at intervals along the circumference of the filter element upper cover 132, in the embodiment of the present application, the height of the water retaining platform 1324 gradually decreases from the direction close to the water outlet 1321 to the direction away from the water outlet 1321, so as to control the water intake of each leakage hole 1322 by the different heights of each water retaining platform 1324, thereby improving the uniformity of the water content in the circumferential direction of the filter element 131.

[0070] In some embodiments, the height of the water retaining platform 1324 is between 0 mm and 1 mm; for example, the height of the water retaining platform 1324 closest to the water outlet 1321 is, for example, 1 mm, and the height of the water retaining platform 1324 between the leakage hole 1322 farthest from the water outlet 1321 and the water diversion groove 1323 is, for example, 0 mm. In this way, the height of the water retaining platform 1324 between the water diversion groove 1323 and each leakage hole 1322 is different depending on the distance from the water outlet 1321, so that the amount of water entering each leakage hole 1322 from the water diversion groove 1323 is basically the same, thereby ensuring the uniformity of the water content in the circumferential direction of the filter element 131.

[0071] In addition, along the extension direction of the water inlet groove 1323, the height difference of adjacent water retaining platforms 1324 includes but is not limited to 0.1 mm, and the specific design can be adaptively continued according to actual conditions; illustratively, along the direction from close to the water outlet 1321 to far away from the water outlet 1321, the height of the water retaining platform 1324 gradually decreases, for example, by 0.1 mm, so that the height of each water retaining platform 1324 is different, so as to control the amount of water entering each leakage hole 1322, and ensure that the leakage amount of the leakage hole 1322 closer to the water outlet 1321 and the leakage hole 1322 farther from the water outlet 1321 is basically consistent, so that the water content of the filter element 131 in the circumferential direction is consistent, so that the water tank 110 takes in air at various angles along its circumference, and the water content carried by the airflow after passing through the filter element 131 is basically the same, thereby ensuring the humidification effect of the humidifier 100.

[0072] It can be understood that by accurately limiting the height difference between adjacent water retaining platforms 1324, the leakage amount of each leakage hole 1322 can be accurately controlled so that the leakage amount of each leakage hole 1322 is the same, thereby improving the uniformity of the water content of the filter element 131 and improving the humidification effect of the humidifier 100.

[0073] In addition, in order to prevent the water flowing out of the water outlet 1321 from directly entering the water leakage hole 1322, in the embodiment of the present application, please continue to refer to Figure 6 and Figure 7 As shown, isolation ribs 1325 are respectively arranged between the water outlet 1321 and the leakage holes 1322 on both sides, so as to isolate the water outlet 1321 from the adjacent leakage holes 1322 through the isolation ribs 1325. In this way, the water flowing out of the water outlet 1321 flows circumferentially along the water diversion groove 1323 under the control and guidance of the isolation ribs 1325. In this way, as long as the water level in the water diversion groove 1323 is higher than the height of the water retaining platform 1324 when the water flows through, part of the water will flow through the corresponding leakage holes 1322 to leak to the filter element 131 below. Since the heights of the water retaining platforms 1324 are different, it can be ensured that the leakage amounts of each leakage hole 1322 are basically the same, thereby improving the uniformity of the water content of the filter element 131.

[0074] Exemplarily, the height of the isolation rib 1325 is, for example, 1 mm to 2 mm. For example, the height of the isolation rib 1325 is 1 mm, 1.8 mm, 1.5 mm, 1 mm, etc., and can be adaptively set according to actual needs as long as the water level of the water flow is lower than the isolation rib 1325. In addition, by limiting the height of the isolation rib 1325, the reliability of the isolation rib 1325 in guiding the water flow is improved.

[0075] The extension path of the isolation rib 1325 can be a straight line or a curve, as long as the flow direction of the water flowing out of the water outlet 1321 can be controlled, and there is no specific limitation.

[0076] In other embodiments, the water inlet groove 1323 is not provided on the filter element upper cover 132, but the aperture sizes of each leakage hole 1322 are different along the circumference of the filter element upper cover 132, so that the leakage difficulty of each leakage hole 1322 is different. For example, the aperture size of the leakage hole 1322 close to the water outlet 1321 is smaller than the aperture size of the leakage hole 1322 far from the water outlet 1321, so that the leakage difficulty of the leakage hole 1322 close to the water outlet 1321 is greater than the leakage difficulty of the leakage hole 1322 far from the water outlet 1321, so that the water intake amount entering each leakage hole 1322 is controlled according to the size of the leakage hole 1322, so that the water content of the filter element 131 along the circumference is basically the same, thereby improving the uniformity of the water content of the filter element 131 in the circumferential direction to ensure the humidification effect of the humidifier 100.

[0077] It can be understood that the larger the aperture of the leakage hole 1322, the easier it is to leak, and the smaller the aperture of the leakage hole 1322, the more difficult it is to leak. Therefore, the leakage hole 1322 facing the filter element 131 is controlled by the size of the leakage hole 1322 so that the leakage amount of each leakage hole 1322 remains basically the same.

[0078] In a specific implementation, when the water pump 140 pumps water out of the water tank 110 through the water outlet 1321 on the filter element upper cover 132, the water flowing out of the water outlet 1321 extends along the circumference of the filter element upper cover 132. In this way, when the water flows through each leakage hole 1322, part of the water flows toward the filter element 131 through the leakage hole 1322 to humidify the filter element 131 below.

[0079] It should be noted that a rib is provided at the edge of the filter element upper cover 132 to prevent water from flowing outward from the edge of the filter element upper cover 132 .

[0080] In some embodiments, the aperture size of the leakage hole 1322 gradually increases along the direction from close to the water outlet 1321 to far away from the water outlet 1321. For example, the aperture size of the leakage hole 1322 closest to the water outlet 1321 is smaller, and the aperture size of the leakage hole 1322 farthest from the water outlet 1321 is the largest. In this way, by making the aperture sizes of each leakage hole 1322 different, it is ensured that the leakage amount of each leakage hole 1322 is the same, thereby improving the uniformity of the water content of the filter element 131.

[0081] In addition, since the cross-sectional shape of the leakage hole 1322 is circular, it is easy to form a water film on the surface of the leakage hole 1322, affecting the water intake of each leakage hole 1322. Therefore, in the embodiment of the present application, the cross-sectional shape of each leakage hole 1322 is one of a rectangle, a square or a trapezoid. It is sufficient to avoid the cross-sectional shape of the leakage hole 1322 being circular to improve the water intake reliability of the leakage hole 1322, thereby ensuring the uniformity of the water content in the circumferential direction of the filter element 131 and improving the humidification effect of the humidifier 100.

[0082] It should be noted that the cross section of the water leakage hole 1322 is, for example, the cross-sectional shape of the water leakage hole 1322 obtained by cutting along a plane perpendicular to the axial direction of the water leakage hole 1322 .

[0083] The humidifier provided in the embodiment of the present application includes a water tank, a filter element bracket and a filter element assembly, the filter element bracket is located in the water tank, and the filter element assembly is arranged on the filter element bracket; the filter element assembly includes a filter element, a filter element upper cover and a filter element lower cover, the filter element is clamped between the filter element upper cover and the filter element lower cover, the filter element upper cover is provided with a water outlet and a water diversion structure, the water diversion structure includes a plurality of leakage holes, and the plurality of leakage holes and the water outlet are arranged at intervals along the circumference of the filter element upper cover, so that the water flowing out of the water outlet enters each leakage hole along the circumference of the filter element upper cover to wet the filter element, and the leakage difficulty of the leakage hole close to the water outlet is greater than the leakage difficulty of the leakage hole far from the water outlet, so that the leakage amount of each leakage hole can be made basically the same, so as to improve the uniformity of the water content of the filter element, thereby improving the humidification effect of the humidifier.
