[0082] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are 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 a person of ordinary skill in the art without creative work fall within the protection scope of the present application. The embodiments described below and the features in the embodiments can be combined with each other without conflict, if possible.

[0083] 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 by taking the mist-free humidifier as an example.

[0084] Please refer to Figure 1 The humidifier 10 provided by the embodiments of the present application includes a humidifier host 100, a filter element assembly 200, and a water tank 300. The water tank 300 is arranged above the humidifier host 100, and the filter element assembly 200 is arranged between the humidifier host 100 and the water tank 300.

[0085] 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 element 210 will be collectively referred to as water, and will not be described specifically.

[0086] In some embodiments, please refer to Figure 2As shown, the humidifier main machine 100 comprises a main machine shell 110, a fan assembly 120, an air duct piece 123 and a water storage tray 130. The main machine shell 110 has a receiving cavity. The main machine shell 110 has an air inlet hole 111 on the side wall close to the bottom. The air inlet hole 111 is in communication with the receiving cavity and the outside of the main machine shell 110, so that the external air can enter the receiving cavity through the air inlet hole 111. The air duct piece 123 and the water storage tray 130 are arranged in the receiving cavity. The air duct piece 123 has an air duct with two open ends. The fan assembly 120 is arranged in the air duct. The water storage tray 130 is arranged above the air duct piece 123 and is sealingly connected with the cavity wall of the receiving cavity. The fan assembly 120 comprises a motor 121 and a fan 122 connected with the motor 121. The motor 121 is fixedly connected to the bottom of the water storage tray 130. The water storage tray 130 has a water storage groove 131 and an air outlet grille 132 arranged around the outer circumferential side of the water storage groove 131. A filter core assembly 200 is arranged above the water storage tray 130, and part of the filter core assembly 200 is located in the water storage groove 131.

[0087] Please refer to Figure 3 As shown, the filter core assembly 200 comprises a filter core 210. The bottom wall of the water tank 300 has an openable and closable water outlet hole. Since the water tank 300 is arranged above the filter core assembly 200, after water is added into the water tank 300, when the humidifier 10 is working, the water outlet hole can be opened, so that the water in the water tank 300 can drip and flow to the filter core 210 through the water outlet hole, so as to wet the filter core 210. When the humidifier 10 stops working or the water in the water tank 300 is not needed to be discharged, the water outlet hole is closed, that is, the water in the water tank 300 stops dripping to the filter core assembly 200. In this way, when the motor 121 is powered on and started, the fan 122 rotates under the drive of the motor 121 to drive the air flow, so as to accelerate the flow rate of the air flow entering the receiving cavity through the air inlet hole 111. The flowing air flow blows to the wet filter core 210 through the air outlet grille 132. The air flow passing through the filter core 210 can evaporate the water on the filter core 210 to the air, thereby increasing the humidity of the air. In addition, this humidifying 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.

[0088] As can be seen, in the embodiment of the present application, the water pump is not additionally arranged to pump the water in the water tank 300 to the filter core assembly 200. Compared with the traditional humidifier 10 provided with a water pump, the humidifier 10 provided in the embodiment of the present application has no noise generated by the water pump 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.

[0089] In some embodiments, the humidifier 10 further comprises a valve assembly 400 arranged at the drain hole, the valve assembly 400 is configured to open or close the drain hole, so that the opening and closing state of the drain hole can be accurately controlled, thereby improving the user experience.

[0090] Wherein, the valve assembly 400 can be manually or automatically activated, so that the drain hole can be selectively opened according to actual needs, so as to meet the actual needs of the user.

[0091] In some embodiments, please refer to Figures 3 to 7 , the valve assembly 400 comprises a valve body 410 and a sealing member 420, the valve body 410 is arranged in the drain hole, and the sealing member 420 is arranged at one end of the valve body 410 facing the water tank 300. The valve body 410 drives the sealing member 420 to move along the axial direction of the drain hole between the first position and the second position under the action of force, so that the sealing member 420 is blocked in the drain hole or removed from the drain hole to unseal the drain hole; for example, as shown in Figure 3 and Figure 4 , the valve body 410 moves along the axial direction of the drain hole from the first position to the second position (for example, upward along the vertical direction), so that the sealing member 420 is removed from the drain hole by the valve body 410, and the water in the water tank 300 can drip through the drain hole; when the valve body 410 drives the sealing member 420 to move along the axial direction of the drain hole from the second position to the first position (for example, downward along the vertical direction), so that the sealing member 420 is blocked in the drain hole, the water in the water tank 300 stops dripping through the drain hole (as shown in Figure 5 and Figure 6 ), so that the sealing member 420 is moved along the axial direction of the drain hole by the valve body 410, so as to realize the opening or closing of the drain hole.

[0092] In some embodiments, please refer to Figure 7 , the water tank 300 comprises a tank body 310 and a tank cover 320, the tank cover 320 can be arranged on the tank body 310 or detached from the tank body 310, so as to facilitate opening the tank cover 320 to add water to the water tank 300 or clean the inside of the tank body 310; in addition, when the humidifier 10 is normally running, the tank cover 320 arranged on the tank body 310 can prevent dust particles and the like from entering the tank body 310, thereby improving the user experience.

[0093] The drain hole is arranged on the bottom wall of the box body 310, the valve body 410 can be a rod-shaped structure, for example, the valve body 410 is in any shape such as circular, oval, polygonal, etc., the profile shape of the drain hole matches the profile shape of the cross section of the valve body 410, so that the valve body 410 is arranged in the drain hole, and the sealing member 420 can be a sealing ring made of rubber, silica gel or other materials with sealing performance, the sealing ring is sleeved on the top end of the valve body 410, for example, Figure 4 and Figure 6 The sealing member 420 is a sealing ring in the shape of an umbrella, when the valve body 410 moves downward to abut against the inner bottom wall of the water tank 300, the sealing ring seals the gap between the valve body 410 and the hole wall of the drain hole, so as to prevent water from leaking through the gap between the drain hole and the valve body 410, thereby improving the sealing performance of the drain hole when it is closed; when the valve body 410 moves upward to a certain height, the sealing member 420 unseals the drain hole, so that the drain hole is opened, therefore, without the need of an additional water pump, as long as the sealing member 420 moves with the valve body 410, the opening and closing state of the drain hole can be realized.

[0094] In some embodiments, please continue to refer to Figures 5 to 7 The valve body assembly 400 further comprises a first elastic member 430, the end of the valve body 410 away from the sealing member 420 is provided with a limiting portion 411, and the first elastic member 430 is arranged between the limiting portion 411 and the outer bottom wall of the water tank 300, so that when the sealing member 420 blocks the drain hole, the first elastic member 430 can drive the valve body 410 to further move downward along the axial direction of the drain hole by the elastic force of the first elastic member 430, so as to improve the fitting force between the sealing member 420 and the bottom wall of the water tank 300, thereby improving the reliability of the sealing member 420 in sealing the gap between the drain hole and the valve body 410.

[0095] For example, the first elastic member 430 includes but is not limited to a spring; for example, in Figure 6 and Figure 7 The first elastic member 430 is a spring, the spring is sleeved on the valve body 410, and the limiting portion 411 is a limiting boss, when the valve body 410 drives the sealing member 420 to move upward to open the drain hole, the first elastic member 430 is in a compressed state, when the valve body 410 drives the sealing member 420 to move downward, the first elastic member 430 can drive the valve body 410 to accelerate downward movement by the elastic force of the first elastic member 430, and when the sealing member 420 abuts against the bottom wall of the water tank 300, the first elastic member 430 can improve the abutting reliability between the sealing member 420 and the bottom wall of the water tank 300, thereby improving the reliability of the sealing member 420 in sealing the drain hole.

[0096] In some embodiments, the humidifier 10 further comprises a floating mechanism 500 connected with the valve body 410, the floating mechanism 500 can be floated up and down in the vertical direction to drive the valve body 410 to move in the axial direction of the drain hole, so as to improve the automation degree of the valve body 410 driving the sealing member 420 to move, without manual operation, and improve the user experience; for example, when the drain hole needs to be opened, the floating mechanism 500 drives the valve body 410 to drive the sealing member 420 to move upward in the axial direction of the drain hole; when the drain hole needs to be closed, the floating mechanism 500 drives the valve body 410 to drive the sealing member 420 to move downward in the axial direction of the drain hole, so as to block the gap between the sealing member 420 and the valve body 410.

[0097] In some embodiments, as shown in Figure 4 , Figure 6 and Figure 8 , the floating mechanism 500 comprises a floating member 510 and a connecting rod 520, the connecting rod 520 is connected between the valve body 410 and the floating member 510, the floating member 510 is configured to be lifted up and down in the vertical direction to drive the valve body 410 to move in the drain hole through the connecting rod 520, wherein the movement direction of the floating member 510 is opposite to the movement direction of the valve body 410; for example, when the floating member 510 moves upward, the floating member 510 drives the valve body 410 to move downward through the connecting rod 520 to close the drain hole; when the floating member 510 moves downward, the floating member 510 drives the valve body 410 to move upward through the connecting rod 520 to open the drain hole.

[0098] In some embodiments, as shown in Figure 8 , Figure 10 , Figure 13 and Figures 17 to 20 , the connecting rod 520 comprises a first sub-connecting rod 520a and a second sub-connecting rod 520b connected with each other, wherein the first sub-connecting rod 520a and the second sub-connecting rod 520b have an inclined included angle; for example, in Figure 8 , Figure 10 and Figure 13 , the included angle between the first sub-connecting rod 520a and the second sub-connecting rod 520b is greater than or equal to 90 degrees, i.e. the included angle between the first sub-connecting rod 520a and the second sub-connecting rod 520b is obtuse; for another example, in Figures 17 to 20 , the included angle between the first sub-connecting rod 520a and the second sub-connecting rod 520b is between 80° and 130°, wherein one end of the first sub-connecting rod 520a away from the second sub-connecting rod 520b is connected with the valve body 410, and one end of the second sub-connecting rod 520b away from the first sub-connecting rod 520a is connected with the floating member 510.

[0099] In the embodiment of the present application, the connecting rod 520 is arranged between the floating member 510 and the valve body 410, and the connecting rod 520 can effectively transmit and amplify the force of the floating member 510, so that a small driving force can reliably control the valve body 410, thereby improving the overall reliability and operation simplicity of the floating mechanism 500.

[0100] In addition, in order to realize the movement of the valve body 410 driven by the connecting rod 520 during the up-and-down floating of the floating member 510, and make the movement direction of the valve body 410 opposite to the lifting direction of the floating member 510, the connecting rod 520 can be arranged to rotate around a horizontal fixed axis with the filter element assembly 200, so that when the floating member 510 drives the one end of the connecting rod 520 to move upward, the other end of the connecting rod 520 drives the valve body 410 to move downward relative to the floating member 510.

[0101] The horizontal fixed axis refers to a direction perpendicular or approximately perpendicular to the vertical direction, and the horizontal direction of the horizontal fixed axis can be set according to actual needs, for example, the horizontal direction can be along the left-right direction, the front-back direction, or a direction having an angle with the left-right direction and the front-back direction, which is not limited herein.

[0102] In order to further reduce the cost of the humidifier 10, in the embodiment of the present application, the floating member 510 can be a structure made of a material capable of floating on water, for example, the floating member 510 includes but is not limited to a floating bottle, a floating block, etc. The filter element assembly 200 further includes a water storage tray 130 having a water storage groove 131, and the filter element 210 and the floating member 510 are located in the water storage groove 131. When the water on the filter element 210 is not absorbed by the filter element 210, the water can flow to the water storage groove 131 along the filter element 210, thereby avoiding the water on the filter element 210 flowing into the humidifier main machine 100, causing the motor 121 to be damaged due to water ingress, etc. As the amount of water collected in the water storage groove 131 increases, the floating member is arranged in the water storage groove 131 and floats upward along the vertical direction as the water level in the water storage groove 131 increases. At this time, the floating member can drive the valve body 410 to move downward through the connecting rod 520. When the water level in the water storage groove 131 reaches a certain height, the sealing member 420 blocks the drain hole, thereby achieving the purpose of closing the drain hole to avoid the water in the water tank 300 continuing to drip through the drain hole, causing the water in the water storage groove 131 to overflow and flow into the humidifier main machine 100. As the water level in the water storage groove 131 continuously decreases, the floating member moves downward as the water level decreases. At this time, the floating member drives the valve body 410 to move upward through the connecting rod 520. When the water level in the water storage groove 131 decreases to a certain height, the sealing member 420 is removed from the drain hole to unseal the drain hole. The water in the water tank 300 drips through the drain hole and flows to the filter element 210, thereby achieving the purpose of wetting the filter element 210.

[0103] Therefore, in the embodiment of the present application, by setting the floating member 510 as a floating member, the floating member can adaptively float up and down with the change of the water level in the water storage tank 131, thereby achieving the purpose of automatically closing the drain hole when there is more water in the water storage tank 131, and automatically opening the drain hole when there is less water in the water storage tank 131. The opening or closing of the drain hole does not require additional power consumption, and can accurately automatically open or close the drain hole with the change of the water level in the water storage tank 131. The structure is simple, energy-saving and environmentally friendly, the cost is low, noise can be avoided, and the user's use experience and the performance-price ratio of the humidifier 10 are improved.

[0104] In some embodiments, referring to Figures 8 to 11 , the filter core assembly 200 further includes a filter core upper cover 220, the filter core upper cover 220 has a liquid containing groove 221, the liquid containing groove 221 is located below the drain hole, the filter core 210 is surrounded on the outer peripheral side of the liquid containing groove 221, the groove wall of the liquid containing groove 221 has a water outlet 2211, the water dripping into the liquid containing groove 221 can flow to the filter core 210 through the water outlet 2211; wherein the water outlet 2211 has a plurality of water outlets 2211, the plurality of water outlets 2211 are arranged on the groove wall of the liquid containing groove 221 and are spaced apart along the circumference of the liquid containing groove 221, so that the water dripping into the liquid containing groove 221 can flow to the filter core 210 through the water outlets 2211 around. In this way, the water dripping through the drain hole can be buffered in the liquid containing groove 221, and then flow to the filter core 210 through the water outlet 2211, so as to ensure the stability and consistency of the water flow to the filter core 210, and improve the uniformity of the humidity of the filter core 210, and improve the effective humidifying area of the filter core 210, thereby improving the humidifying efficiency and effect.

[0105] For example, as shown in Figures 8 to 11 , the plurality of water outlets 2211 are arranged on the groove side wall of the liquid containing groove 221 and are uniformly arranged at equal intervals along the circumference of the liquid containing groove 221. Among them, the water outlet 2211 is arranged at a position close to the bottom of the liquid containing groove 221. Compared with the water outlet 2211 arranged at a higher position on the groove side wall of the liquid containing groove 221, when there is a small amount of water in the liquid containing groove 221, the height of the water outlet 2211 can be reached, and the water can flow to the filter core 210 through the water outlet 2211 to achieve the purpose of wetting the filter core 210. Without the water in the liquid containing groove 221 reaching a certain height to reach the height of the water outlet 2211, the water dripping into the liquid containing groove 221 through the drain hole of the lower water tank 300 can flow to the filter core 210 in time, thereby shortening the time of wetting the filter core 210 and improving the humidifying efficiency and use experience of the humidifier 10.

[0106] In some embodiments, referring to Figure 4 , Figure 6 and Figure 10As shown, the bottom of the liquid tank 221 has a water outlet point and a flow guide structure 2214, the flow guide structure 2214 is located at the outer circumferential side of the water outlet point, and the water outlet point is located directly below the water outlet hole, that is, the water in the water tank 300 drips to the water outlet point through the water outlet hole, so that the water dripping to the water outlet point is guided to the water outlets 2211 around by the flow guide structure 2214, so that the water dripping into the liquid tank 221 can flow to the filter element 210 through the water outlets 2211 around to improve the humidity uniformity of the filter element 210.

[0107] It should be noted that the water outlet point refers to the corresponding dripping position when the water drips into the liquid tank 221 through the water outlet hole, which can be the area corresponding to the water dripping through the water outlet hole.

[0108] Exemplarily, in Figure 4 , Figure 6 and Figure 10 , the bottom of the liquid tank 221 is a conical protrusion protruding upward, so that the highest point of the conical protrusion is located directly below the water outlet hole to form the water outlet point, and the conical surface of the conical protrusion is formed as the flow guide structure 2214, so that the water dripping onto the conical protrusion flows to the water outlets 2211 around along the conical surface in a rotary structure, thereby improving the uniformity of the water flowing to the water outlets 2211 around, thereby improving the humidity uniformity of the filter element 210 in the circumferential direction, and further improving the humidification efficiency and effect.

[0109] Since the floating member is arranged in the water storage tank 131, in order to realize the connection of the connecting rod 520 and the valve body 410, in the embodiments of the present application, please refer to Figure 8 , Figure 10 and Figure 11 , the floating mechanism 500 further comprises a top rod 530, the top rod 530 penetrates the bottom wall of the liquid tank 221 and is connected between the valve body 410 and the connecting rod 520, so that the connecting rod 520 can apply upward or downward driving force to the valve body 410 through the top rod 530 to drive the valve body 410 to move in the water outlet hole.

[0110] In some embodiments, please continue to refer to Figure 4 , Figure 6 , Figure 8 and Figure 10 and Figure 11As shown, the floating mechanism 500 further comprises a second elastic member 540, wherein the second elastic member 540 comprises but is not limited to a spring, one end of the top rod 530 close to the valve body 410 is provided with a first limiting structure 531, and the second elastic member 540 is arranged between the first limiting structure 531 and the bottom wall of the liquid containing groove 221. When the connecting rod 520 drives the valve body 410 to move downward and close the drain hole through the top rod 530, the second elastic member 540 is in a compressed state. When the driving force of the connecting rod 520 to the valve body 410 is removed through the top rod 530, the second elastic member 540 can drive the top rod 530 to move to one side of the valve body 410 through the elastic force of the second elastic member 540, that is, the second elastic member 540 can drive the top rod 530 to push the valve body 410 to reset through the elastic force of the second elastic member 540, which saves time and effort, has a simple structure and low cost.

[0111] In some embodiments, please refer to Figures 3 to 6 As shown, the floating member 510 is a floating bottle, the first end of the connecting rod 520 is connected with the valve body 410 through the top rod 530, and the second end of the connecting rod 520 is in a free state and located above the floating bottle 510, wherein the elastic force of the second elastic member 540 is greater than the elastic force of the first elastic member 430. In this way, when the floating bottle floats upward with the rising water level in the water storage tank 131, the floating bottle abuts against the second end of the connecting rod 520 and pushes the second end of the connecting rod 520 upward with the continuous upward floating of the floating bottle, the connecting rod 520 rotates relative to the filter core assembly 200, and the first end of the connecting rod 520 drives the valve body 410 to move downward through the top rod 530. At this time, the valve body 410 moves downward under the driving force of the top rod 530 downward and the elastic force of the first elastic member 430 to block the drain hole through the sealing member 420. When the water storage tank 131 is short of water, the floating bottle floats downward with the lowering of the water level in the water storage tank 131, the second end of the connecting rod 520 is in a free state at this time, and the driving force of the connecting rod 520 to the valve body 410 downward through the top rod 530 is removed. In this way, the second elastic member 540 drives the top rod 530 to push the valve body 410 to overcome the elastic force of the first elastic member 430 under the elastic force of the second elastic member 540, so that the valve body 410 drives the sealing member 420 to unblock the drain hole, that is, to open the drain hole. In this way, the water in the water tank 300 can continue to drip into the liquid containing groove 221 through the drain hole, so that the water dripping into the liquid containing groove 221 can flow to the filter core 210 through the four peripheral water outlets 2211 to achieve the purpose of wetting the filter core 210.

[0112] In some embodiments, please refer to Figure 12 and Figure 13As shown, the outer bottom wall of the liquid tank 221 has an extension 2212, the side wall near the first end of the connecting rod 520 has a rotating shaft 522, and the rotating shaft 522 is rotationally connected with the extension 2212; when the floating member 510 is in contact with the second end of the connecting rod 520 and moves upward in the vertical direction, the first end of the connecting rod 520 drives the valve body 410 to move downward in the vertical direction, so that the sealing member 420 is blocked at the drain hole.

[0113] As shown in the examples, Figure 12 As shown in the examples, the filter core assembly 200 further includes a limiting member 240, the bottom wall of the extension 2212 has a first rotating groove 2213 with a bottom opening, the rotating shaft 522 is rotationally arranged in the first rotating groove 2213, and the limiting member 240 is arranged on the side of the rotating shaft 522 away from the extension 2212 and is detachably connected with the extension 2212, for example, the limiting member 240 is a limiting pressing plate, which is clamped, threadedly connected or magnetically connected with the top rod 530; in this way, when the second end of the connecting rod 520 moves upward with the floating bottle, the connecting rod 520 rotates relative to the extension 2212, the first end of the connecting rod 520 can push the limiting pressing plate, so that the limiting pressing plate drives the top rod 530 to move downward, thereby driving the valve body 410 to move downward to close the drain hole; when the water in the water storage tank 131 is insufficient, the floating bottle moves downward, at this time, the second elastic member 540 drives the top rod 530 to push the valve body 410 to move upward to open the drain hole under the action of its own elasticity, the top rod 530 drives the limiting pressing plate to push the first end of the connecting rod 520 to move upward, and the second end of the connecting rod 520 moves downward to reset the connecting rod 520.

[0114] In some embodiments, as shown in the examples, Figures 3 to 6 , Figure 14 As shown in the examples, the water storage disc 130 has a mounting boss 135, and the floating member 510 has a bottom-opening avoiding groove 511, for example, the floating member 510 is a hollow floating bottle, and the floating bottle is covered on the mounting boss 135; in this way, the mounting boss 135 can limit the circumferential direction of the floating bottle, and can avoid the floating bottle moving in the circumferential direction in the water storage tank 131 to affect the reliability of triggering the connecting rod 520; therefore, the mounting boss 135 and the avoiding groove 511 are equivalent to a guide structure, which can guide the upward and downward floating of the floating bottle, thereby improving the route accuracy of the upward and downward floating of the floating bottle.

[0115] In addition, the floating mechanism 500 comprises two connecting rods 520, the two connecting rods 520 are arranged on both sides of the top rod 530 and are connected with the top rod 530, and the ends of the two connecting rods 520 away from the top rod 530 are located above the floating element 510; when the floating element 510 moves upward along the vertical direction, the floating element 510 pushes the two connecting rods 520, so that the two connecting rods 520 drive the valve body 410 to move downward along the axial direction of the drain hole through the top rod 530, so that the force transmitted by the floating element 510 can be uniformly transmitted to the top rod 530 through the two connecting rods 520, and the stability of the movement of the top rod 530 driving the valve body 410 is improved.

[0116] In some embodiments, referring to Figures 14 to 16 The humidifier 10 further comprises a water shortage protection switch 600, which is electrically connected with the humidifier main machine 100, for example, the water shortage protection switch 600 is electrically connected with the motor 121 in the humidifier main machine 100, when the water storage tank 131 is short of water, in order to avoid the phenomenon of dry burning of the humidifier 10, the water shortage protection switch 600 is triggered or untriggered when the water storage tank 131 is short of water, so that the humidifier main machine 100 is in a power-off state, that is, the humidifier 10 automatically stops when the water is short, so as to improve the safety and reliability of the humidifier 10 and prolong the service life of the humidifier 10.

[0117] In some embodiments, the water shortage protection switch 600 is arranged on one of the mounting boss 135 and the groove bottom of the avoidance groove 511, when the floating element 510 floats up and down along the vertical direction with the water level, the water shortage protection switch 600 is triggered or untriggered, so that the humidifier main machine 100 is powered off or powered on; for example, when the water shortage protection switch 600 is triggered, the humidifier main machine 100 is powered off; when the water shortage protection switch 600 is untriggered, the humidifier main machine 100 is automatically powered on.

[0118] In the embodiments of the present application, first, the water shortage protection switch 600 is arranged, so as to protect the humidifier 10 from water shortage; in addition, the water shortage protection switch 600 is arranged between the floating element 510 and the mounting boss 135, so that when the floating element 510 rises and falls with the water level, the water shortage protection switch 600 can be triggered or untriggered, so that the water shortage protection can be accurately realized, without the need for additional parts to trigger the water shortage protection switch 600, the structure is simple, the cost is low, and the overall structure compactness of the humidifier 10 is improved, so as to realize the purposes of light weight and small size of the humidifier 10.

[0119] For example, as Figure 15 and Figure 16As shown in FIG. 1, the water shortage protection switch 600 is mounted on the mounting boss 135 and electrically connected with the motor 121 below the water shortage protection switch 600. The water shortage protection switch 600 has a trigger portion at the top, which can move in the vertical direction. When the water level in the water storage tank 131 continuously decreases, the groove bottom of the avoiding groove 511 contacts with the trigger portion and pushes the trigger portion to move downward. When the water storage tank 131 is in the water shortage state, the groove bottom of the avoiding groove 511 contacts with the trigger portion. At this time, the motor 121 is in the power-off state. When the water storage tank 131 has water and the water level in the water storage tank 131 continuously rises, the groove bottom of the avoiding groove 511 is disengaged from the trigger portion, the trigger portion moves upward, the water shortage protection switch 600 is in the untriggered state, and the motor 121 is in the power-on state. At this time, the humidifier 10 can normally operate.

[0120] In order to further improve the accuracy of the up-and-down floating route of the floating member 510, the mounting boss 135 has a first guide portion, and the floating member 510 has a second guide portion matched with the first guide portion. When the floating member 510 moves up and down, the first guide portion moves along the second guide portion. In this way, when the floating member 510 floats up and down with the change of the water level in the water storage tank 131, the floating member 510 moves along the extension direction of the first guide portion through the second guide portion, so as to improve the route accuracy of the floating member 510 when floating up and down, thereby improving the accuracy and reliability of the trigger connecting rod 520 and the water shortage protection switch 600.

[0121] For example, the first guide portion is one of the guide column 136 and the guide hole, and the second guide portion is the other one of the guide column 136 and the guide hole. For example, in Figure 14 In the embodiment, the first guide portion is the guide column 136 extending in the vertical direction, and the second guide portion is the guide hole matched with the guide column 136. The guide column 136 is arranged in the guide hole, so that the floating member 510 floats up and down along the guide column 136.

[0122] In some embodiments, please refer to Figure 4 and Figure 6 As shown in FIG. 1, the humidifier 10 further comprises a limiting screw 550, and the guide column 136 has a threaded hole matched with the limiting screw 550. After the guide column 136 passes through the floating member 510, the limiting screw 550 is screwed with the threaded hole at the top end of the guide column 136. In this way, the nut of the limiting screw 550 can limit the movement of the floating member 510 in the vertical direction, so as to prevent the floating member 510 from falling off the guide column 136.

[0123] In other embodiments, the structure of the connecting rod 520 and the structure of the floating member 510 are different from those of the connecting rod 520 and the floating member 510 provided in the above embodiments. Please refer to Figures 17 to 20As shown in FIG. 1, in the embodiment of the present application, the first end of the connecting rod 520 has an abutting portion 521 extending towards the side of the valve body 410, the top rod 530 is connected between the abutting portion 521 and the valve body 410, the water storage tray 130 has a mounting seat 134, the mounting seat 134 has a second rotating groove 1341, the side wall of the connecting rod 520 has a rotating shaft 522, the rotating shaft 522 is rotationally connected with the second rotating groove 1341 of the mounting seat 134, and the second end of the connecting rod 520 is detachably connected with the floating member 510; when the floating member 510 drives the second end of the connecting rod 520 to move downward along the vertical direction with the decrease of the water level in the water storage tank 131, the first end of the connecting rod 520 pushes the top rod 530 through the abutting portion 521, so that the top rod 530 pushes the valve body 410 to move upward along the vertical direction, so as to remove the sealing member 420 from the drain hole to open the drain hole; when the floating member 510 drives the second end of the connecting rod 520 to move upward along the vertical direction with the increase of the water level in the water storage tank 131, the second end of the connecting rod 520 moves downward, at this time, the top rod 530 and the valve body 410 move downward under the action of the elastic force of the first elastic member 430 and the gravity of the top rod 530 and the valve body 410, so as to block the drain hole by the sealing member 420, thereby closing the drain hole.

[0124] For example, as shown in FIG. 1, the first end of the connecting rod 520 has the abutting portion 521 extending towards the side of the valve body 410, and the top rod 530 is connected between the abutting portion 521 and the valve body 410. Figures 17 to 20 As shown in FIG. 1, when the second end of the connecting rod 520 is connected with the floating member 510, the floating member 510 can be a floating block, and the height of the floating block is lower than the height of the water storage tank 131. Compared with the floating member being a floating bottle, the space occupied by the floating member 510 in the humidifier 10 can be reduced, and the second elastic member 540 does not need to be additionally arranged, so that the structural compactness of the humidifier 10 can be further improved, the number of parts can be reduced, and the cost can be reduced.

[0125] In some embodiments, the connecting rod 520 and the floating member 510 are detachably connected, so that the floating member 510 and the connecting rod 520 can be replaced or maintained after being detached.

[0126] In addition, whether the floating member 510 is a floating bottle or a floating block, in some embodiments, please refer to Figure 4 , Figure 6 , Figure 18 and Figure 20 As shown in FIG. 1, the end of the top rod 530 towards the connecting rod 520 has the second limiting structure 532, the second limiting structure 532 is configured to limit the upward movement of the top rod 530 along the vertical direction, and the first limiting structure 531 of the end of the top rod 530 facing the valve body 410 can limit the downward movement of the top rod 530 along the vertical direction, so that the top rod 530 can be prevented from falling off the groove bottom of the liquid containing groove 221, and the reliability of the top rod 530 penetrating the groove bottom of the liquid containing groove 221 can be improved.

[0127] In order to further improve the overall structural compactness of the humidifier 10, please refer to Figure 4 ,Figure 6 , Figure 18 as well as Figure 20 As shown, the bottom of the water storage tray 130 has a recessed clearance space 137 facing the water tank 300. The motor 121 is located in the clearance space 137, and the fan 122 is located below the motor 121 and connected to the output shaft of the motor 121. In this way, the overall structural compactness of the humidifier 10 can be improved.

[0128] In some embodiments, please return to the reference. Figures 3 to 6 , Figures 8 to 10 As shown, the filter element assembly 200 includes an upper filter element cover 220 and a lower filter element cover 230. The upper filter element cover 220 and the lower filter element cover 230 are arranged opposite to each other and connected. The upper filter element cover 220 and the lower filter element cover 230 together form an annular cavity. The lower filter element cover 230 has an air inlet communicating with the annular cavity, and the upper filter element cover 220 has an air outlet 2231 communicating with the annular cavity. The air inlet, the annular cavity, and the air outlet 2231 form an airflow channel. The filter element 210 is disposed on the airflow channel. In this way, the airflow blown towards the filter element assembly 200 through the air outlet grille 132 can pass through the air inlet, the filter element 210, and the air outlet 2231 to naturally evaporate the moisture on the filter element 210 into the air, thereby increasing the humidity of the air and achieving the purpose of humidifying the air.

[0129] In some embodiments, please return to the reference. Figures 8 to 10 As shown, the filter element lower cover 230 has a first windbreak 231, and the filter element 210 has a water-retaining part 211 located in the water storage tank 131. The filter element lower cover 230 has a through hole at a position corresponding to the water-retaining part 211. In this way, excess water on the filter element 210 can flow downward along the filter element 210 and flow into the water storage tank 131 through the water-retaining part 211, thereby preventing water on the filter element 210 from entering the humidifier main unit 100 and affecting the life of the internal components of the humidifier main unit 100.

[0130] In some embodiments, the filter element 210 has a ring structure, the submerged part 211 is arranged at the bottom of the filter element 210 and close to the inner side of the ring, and the first wind blocking part 231 is arranged on the inner wall surface of the filter element 210; the filter element upper cover 220 includes a second wind blocking part 222, a grid part 223, and a support part 224, the second wind blocking part 222 is arranged on the inner wall surface of the filter element 210 and above the first wind blocking part 231, and the first wind blocking part 231 and the second wind blocking part 222 are detachably connected, the first wind blocking part 231 and the second wind blocking part 222 are arranged together to form a cylindrical structure, and the filter element 210 is arranged outside the formed cylindrical structure to block the wind through the first wind blocking part 231 and the second wind blocking part 222, so as to prevent the airflow passing through the filter element 210 from flowing along the circumferential direction of the filter element 210 to the inner side of the ring of the filter element 210, thereby improving the guidance of the airflow flowing through the filter element 210, so that the airflow blown to the filter element 210 by the air outlet grid 132 directly passes through the wet filter element 210 from bottom to top, thereby improving the efficiency and effect of the airflow passing through the filter element 210, and further improving the humidification effect and efficiency. In addition, the support part 224 is arranged around the outer circumferential side of the filter element 210, the grid part 223 is arranged at the air outlet end of the filter element 210 and connected with the support part 224 and the second wind blocking part 222 respectively, and one end of the support part 224 away from the grid part 223 is connected with the main machine shell 110, so as to provide a support basis for the outer circumferential side of the filter element 210 and improve the support reliability of the filter element 210.

[0131] The grid part 223 includes a plurality of wind guide grid bars 2232, the plurality of wind guide grid bars 2232 are arranged at intervals along the circumferential direction of the filter element 210, one end of each wind guide grid bar 2232 is connected with the support part 224, and the other end is connected with the second wind blocking part 222, and an air outlet 2231 is formed between adjacent wind guide grid bars. In this way, the airflow passing through the filter element 210 is discharged through the air outlet 2231 to humidify the air.

[0132] Since the water tank 300 is arranged above the filter element assembly 200, the structure of the water tank 300 will cause a certain wind resistance and affect the air outlet effect. In order to solve the above problem, in some embodiments, please refer to Figure 10 As shown in the figure, the grid part 223 extends to the side wall of the filter element 210 and extends along the circumferential direction of the filter element 210, that is, the air outlet 2231 extends to the side wall of the filter element 210. In this way, the air outlet area can be increased, thereby reducing the loss of airflow volume, and improving the humidification effect and efficiency.

[0133] In other embodiments, please refer to Figure 3 and Figure 5As shown, the outer profile surface of the side of the water tank 300 facing the filter core assembly 200 has a wind guide structure 330 configured to guide the airflow discharged from the air outlet 2231 to the outside of the humidifier 10 to improve the flow guiding property of the airflow, reduce the wind resistance generated by the water tank 300, reduce the loss of air volume, and thus improve the humidifying efficiency and effect.

[0134] For example, the outer profile surface of the side of the water tank 300 facing the filter core assembly 200 is an arc-shaped surface extending away from the side of the filter core assembly 200, wherein the arc-shaped surface is curved towards the side of the filter core assembly 200, and the arc-shaped surface is formed as the wind guide structure 330 to reduce the wind resistance generated by the water tank 300.

[0135] In some embodiments, the water storage tray 130 is arranged in the accommodating cavity and is sealingly connected with the cavity wall of the accommodating cavity. Please refer back to Figure 14 As shown, the water storage tray 130 also has a drainage structure 133, the side wall of the water storage groove 131 has an openable water outlet hole, one end of the drainage structure 133 is connected with the water outlet hole, and the other end extends to the outside of the main machine shell 110. In this way, when it is necessary to clean the water remaining in the water storage groove 131, the water outlet hole can be directly opened, the water in the water storage groove 131 is discharged through the water outlet hole and the drainage structure 133 to the outside of the main machine shell 110, which can avoid the problem that the water needs to pass through the air outlet grille 132 and easily enter the inside of the humidifier main machine 100 when the water is poured through the water storage groove 131, thereby improving the safety and reliability of the humidifier main machine 100 and the simplicity and convenience of the water drainage method.

[0136] For example, the drainage structure 133 has a drainage groove connected between the water outlet hole and the cavity wall of the accommodating cavity. In this way, when it is necessary to clean the water in the water storage groove 131, the water is discharged through the water outlet hole to the drainage groove, and the water flows along the extension direction of the drainage groove towards the cavity wall of the accommodating cavity. In this way, the humidifier main machine 100 can be slightly tilted to make the water flow along the cavity wall of the accommodating cavity to the outside.

[0137] It can be understood that the drainage groove can effectively guide the flow direction of the water discharged through the water outlet hole, so that the water in the water storage groove 131 can be cleaned without passing through the air outlet grille 132, the water can be prevented from entering the inside of the humidifier main machine 100 through the air outlet grille 132, and the smoothness and safety and reliability of the water drainage of the water outlet hole can be improved.

[0138] For another example, the drainage structure 133 can be a drainage pipe, one end of the drainage pipe is connected with the water outlet hole, and the other end extends to the outside of the main machine shell 110. In this way, the water discharged through the water outlet hole can be discharged to the outside of the main machine shell 110 through the drainage pipe.

[0139] To sum up, the humidifier provided by the embodiments of the present application sets the water tank above the main machine of the humidifier, sets the filter element assembly between the water tank and the main machine of the humidifier, and sets an openable drain hole in the bottom wall of the water tank. In this way, when the drain hole is opened, the water in the water tank can drip through the drain hole and flow to the filter element assembly located below the water tank, so as to achieve the purpose of wetting the filter element in the filter element assembly. The water in the water tank does not need to be pumped to the filter element assembly by an additional water pump, so as to avoid the noise generated by the water pump when pumping water, and improve the user experience. In addition, the problem of high cost of the humidifier caused by the setting of the water pump can be improved, the cost is saved, and the economy is improved.
