[0099] Generally, the fog-free humidifier includes a humidifier main machine, a filter core assembly and a water tank assembly. The humidifier main machine is arranged above the water tank assembly, the filter core assembly is arranged between the water tank assembly and the humidifier main machine, and the water tank assembly includes a water tank and a water pump arranged in the water tank. The water pump is used to pump water in the water tank to above the filter core assembly, so that the water can wet the filter core in the filter core assembly from top to bottom. When the humidifier main machine operates, the water on the filter core can be naturally evaporated into the air when the airflow blows through the filter core, so as to achieve the purpose of humidifying the air. However, the water pump is used to pump the water in the water tank to above the filter core. On the one hand, the water pump will produce noise when pumping water. On the other hand, the water pump arranged in the humidifier will cause the overall cost of the humidifier to be relatively high.

[0100] To solve the above problems, the embodiment of the present application provides a humidifier. The water tank is arranged above the humidifier main machine, the filter core assembly is arranged between the humidifier main machine and the water tank, and a lower water hole is arranged on the bottom wall of the water tank. When the lower water hole is opened, the water in the water tank can drip through the lower water hole and flow to the filter core assembly below the water tank to wet the filter core in the filter core assembly. Therefore, the water pump is not needed to pump the water in the water tank to the filter core assembly, so as to avoid the noise produced 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 water pump can be solved, the cost is saved, and the economy is improved.

[0101] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application. The embodiments and features in the embodiments below can be combined with each other without conflict.

[0102] The embodiment of the present application provides a humidifier. The humidifier includes but is not limited to a fog-free humidifier. The structure and working principle of the humidifier will be described in detail below taking the fog-free humidifier as an example.

[0103] Please refer to Figure 1 The humidifier 10 provided by the embodiment of the present application includes a humidifier main machine 100, a filter core assembly 200 and a water tank 300. The water tank 300 is arranged above the humidifier main machine 100, and the filter core assembly 200 is arranged between the humidifier main machine 100 and the water tank 300.

[0104] The water tank 300 is used to store water for humidification of the humidifier 10. The water in the water tank 300 can be pure water or a water solution with additives such as mixed spices, bactericides, essential oils, etc. The embodiments of the present application do not make specific limitations thereon. The liquid used for the filter element 210 will be collectively referred to as water hereinafter and will not be specifically described.

[0105] In some embodiments, referring to Figure 2 The humidifier main machine 100 includes a main machine shell 110, a fan assembly 120, an air duct 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 near 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 external air can enter the receiving cavity through the air inlet hole 111. The air duct 123 and the water storage tray 130 are arranged in the receiving cavity. The air duct 123 has an open end. The fan assembly 120 is arranged in the air duct. The water storage tray 130 is arranged above the air duct 123 and is sealingly connected with the cavity wall of the receiving cavity. The fan assembly 120 includes 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. The filter element assembly 200 is arranged above the water storage tray 130, and part of the filter element assembly 200 is located in the water storage groove 131.

[0106] Referring to Figure 3 The filter element assembly 200 includes a filter element 210. The bottom wall of the water tank 300 has an openable and closable drain hole. Since the water tank 300 is arranged above the filter element assembly 200, when the humidifier 10 is working and water is added to the water tank 300, the drain hole can be opened to allow the water in the water tank 300 to drip and flow to the filter element 210 to wet the filter element 210. When the humidifier 10 stops working or the water tank 300 does not need to drain, the drain hole is closed, that is, the water in the water tank 300 stops dripping to the filter element assembly 200. When the motor 121 is powered on, the fan 122 rotates under the drive of the motor 121 to drive the air flow 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 element 210 through the air outlet grille 132. The air flow passing through the filter element 210 can naturally evaporate the moisture on the filter element 210 into the air 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 bacterial growth, and avoiding potential damage of water mist deposition to furniture and floors.

[0107] Therefore, in the embodiment of the present application, the water pump is not needed to be additionally arranged to pump the water in the water tank 300 to the filter element assembly 200, compared with the humidifier 10 provided with the water pump, the humidifier 10 provided by the embodiment of the present application does not produce the noise generated by the water pump, 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.

[0108] In some embodiments, the humidifier 10 further comprises a switch valve 400, which is arranged at the lower water hole, and the switch valve 400 is configured to open or close the lower water hole, so that the opening and closing state of the lower water hole can be accurately controlled, thereby improving the user experience.

[0109] Among them, the switch valve 400 can be manually or automatically started, so that the lower water hole can be selectively opened according to the actual demand, so as to meet the actual demand of the user.

[0110] In some embodiments, please refer to Figures 3 to 7 , the switch valve 400 has a valve body 410 and a sealing part 420, the valve body 410 is arranged in the lower water hole, the sealing part 420 is arranged at one end of the valve body 410 facing the water tank 300, and the valve body 410 drives the sealing part 420 to move along the axial direction of the lower water hole under the action of force, so as to block the lower water hole or remove the lower water hole; for example, as shown in Figure 3 and Figure 4 , the valve body 410 moves upward along the axial direction of the lower water hole to remove the sealing part 420 from the lower water hole by the valve body 410, and the water in the water tank 300 can drop through the lower water hole; when the valve body 410 drives the sealing part 420 to move downward along the axial direction of the lower water hole, the sealing part 420 is blocked at the lower water hole, so that the water in the water tank 300 stops dropping through the lower water hole (as shown in Figure 5 and Figure 6 ), thereby driving the sealing part 420 to move along the axial direction of the lower water hole by the valve body 410 to realize the opening or closing of the lower water hole.

[0111] 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.

[0112] The drain hole is arranged on the bottom wall of the box 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 part 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 part 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 part 420 unseals the drain hole, so that the drain hole is opened. Therefore, without an additional water pump, the opening and closing state of the drain hole can be realized by moving the sealing part 420 along with the valve body 410.

[0113] In some embodiments, please continue to refer to Figures 5 to 7 The humidifier 10 further comprises a first elastic member 430, the end of the valve body 410 away from the sealing part 420 is provided with a limiting part 411, and the first elastic member 430 is arranged between the limiting part 411 and the outer bottom wall of the water tank 300. In this way, when the sealing part 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 part 420 and the bottom wall of the water tank 300, thereby improving the reliability of the sealing part 420 in sealing the gap between the drain hole and the valve body 410.

[0114] 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 part 411 is a limiting boss. When the valve body 410 drives the sealing part 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 part 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 part 420 abuts against the bottom wall of the water tank 300, the first elastic member 430 can improve the abutting reliability between the sealing part 420 and the bottom wall of the water tank 300, thereby improving the reliability of the sealing part 420 in sealing the drain hole.

[0115] In some embodiments, the humidifier 10 further comprises a driving mechanism 500 connected with the valve body 410 to drive the valve body 410 to move along the axial direction of the drain hole, so as to improve the automation degree of the movement of the valve body 410 and the sealing part 420, and improve the user experience without manual operation; for example, when the drain hole needs to be opened, the driving mechanism 500 drives the valve body 410 to move upward along the axial direction of the drain hole with the sealing part 420; when the drain hole needs to be closed, the driving mechanism 500 drives the valve body 410 to move downward along the axial direction of the drain hole with the sealing part 420, so as to block the gap between the drain hole and the valve body 410.

[0116] In some embodiments, as shown in Figure 4 , Figure 6 and Figure 8 , the driving mechanism 500 comprises a lifting piece 510 and a connecting rod 520, the connecting rod 520 is connected between the valve body 410 and the lifting piece 510, and the lifting piece 510 is configured to move up and down along 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 lifting piece 510 is opposite to the movement direction of the valve body 410; for example, when the lifting piece 510 moves upward, the lifting piece 510 drives the valve body 410 to move downward through the connecting rod 520 to close the drain hole; when the lifting piece 510 moves downward, the lifting piece 510 drives the valve body 410 to move upward through the connecting rod 520 to open the drain hole.

[0117] It can be understood that the connecting rod 520 can effectively transmit and amplify the force of the lifting piece 510, so that a smaller driving force can realize reliable control of the valve body 410, thereby improving the overall reliability and operation simplicity of the driving mechanism 500.

[0118] It can be understood that the connecting rod 520 can effectively transmit and amplify the force of the lifting piece 510, so that a smaller driving force can realize reliable control of the valve body 410, thereby improving the overall reliability and operation simplicity of the driving mechanism 500.

[0119] In addition, in order to realize that the lifting piece 510 drives the valve body 410 to move through the connecting rod 520 during the lifting process, and the movement direction of the valve body 410 is opposite to the lifting direction of the lifting piece 510, the connecting rod 520 can be made to rotate around the axis along the horizontal direction with the filter core assembly 200, so that when the lifting piece 510 drives one end of the connecting rod 520 connected thereto to move upward, the other end of the connecting rod 520 drives the valve body 410 to move downward relative to the lifting piece 510.

[0120] To further reduce the cost of the humidifier 10, in the embodiment of the present application, the lifting piece 510 can be a floating piece, for example, the lifting piece 510 can be a floating bottle, a floating block or the like structure; and the filter element assembly 200 further comprises a water storage tray 130, the water storage tray 130 has a water storage groove 131, and the filter element 210 and the lifting piece 510 are both located in the water storage groove 131, so that when the water on the filter element 210 is not absorbed by the filter element 210, the water can flow along the filter element 210 to the water storage groove 131, thereby avoiding the water on the filter element 210 flowing into the humidifier main machine 100, causing the motor 121 and the like to be damaged due to water ingress and the like; as the water collected in the water storage groove 131 increases, the floating piece 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 piece 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 part 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 be too much and overflow to flow into the humidifier main machine 100; as the water level in the water storage groove 131 continuously decreases, the floating piece moves downward as the water level decreases, at this time, the floating piece 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 part 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.

[0121] As can be seen, in the embodiment of the present application, by setting the lifting piece 510 as a floating piece, the floating piece can automatically float up and down as the water level in the water storage groove 131 changes, thereby achieving the purpose of automatically closing the drain hole when there is too much water in the water storage groove 131, and automatically opening the drain hole when there is not enough water in the water storage groove 131, the opening or closing of the drain hole does not need to consume extra power, can accurately automatically open or close the drain hole as the water level in the water storage groove 131 changes, and has the advantages of simple structure, energy saving and environmental protection, low cost, can avoid generating noise, thereby improving the user's experience and the performance-price ratio of the humidifier 10.

[0122] In some embodiments, please refer to Figures 8 to 11As shown, the filter core assembly 200 further comprises 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 water outlet hole, the filter core 210 is arranged on the outer circumferential side of the liquid containing groove 221, the water outlet 2211 is arranged on the groove wall of the liquid containing groove 221, and 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, and 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 it. In this way, the water dripping through the water outlet hole can be buffered in the liquid containing groove 221, and then flow to the filter core 210 through the water outlet 2211. In this way, the stability and consistency of the water flow to the filter core 210 can be ensured, and the uniformity of the humidity of the filter core 210 can be improved, and the effective humidifying area of the filter core 210 can be improved, thereby improving the humidifying efficiency and effect.

[0123] 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. Therefore, the water in the water tank 300 dripping into the liquid containing groove 221 through the water outlet hole 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.

[0124] In some embodiments, please refer to Figure 4 , Figure 6 and Figure 10 , the bottom of the liquid containing groove 221 has a water outlet point and a flow guide structure 2214, the flow guide structure 2214 is located on 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 into the water outlet point through the water outlet hole. In this way, the water dripping into the water outlet point can be guided to the water outlets 2211 around it through the flow guide structure 2214, so that the water dripping into the liquid containing groove 221 can flow to the filter core 210 uniformly through the water outlets 2211 around it, thereby improving the humidity uniformity of the filter core 210.

[0125] It should be noted that the water outlet point refers to the dripping position corresponding to the water dripping into the liquid containing groove 221 through the water outlet hole, which can be the area corresponding to the water dripping through the water outlet hole.

[0126] As shown in Figure 4、 Figure 6 and Figure 10 In the embodiment, the bottom of the liquid tank 221 is a conical protrusion upwardly protruding, so that the highest point of the conical protrusion is directly below the drain hole to form a drain point, and the conical surface of the conical protrusion is formed as a flow guide structure 2214, so that the water falling on the conical protrusion flows along the conical surface in a rotary structure to the water outlets 2211 around, thereby improving the uniformity of the water flow to the water outlets 2211 around, improving the humidity uniformity of the filter core 210 in the circumferential direction, and further improving the humidification efficiency and effect.

[0127] Since the floating member is arranged in the water storage tank 131, in order to realize the connection between the connecting rod 520 and the valve body 410, in the embodiment, please refer to Figure 8 、 Figure 10 and Figure 11 It is shown that the driving 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 drain hole.

[0128] In some embodiments, please continue to refer to Figure 4 、 Figure 6 、 Figure 8 and Figure 10 and Figure 11 It is shown that the driving mechanism 500 further comprises a second elastic member 540, wherein the second elastic member 540 includes but is not limited to a spring, one end of the top rod 530 close to the valve body 410 has 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 tank 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 itself, 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 itself, which saves time and effort, has simple structure and low cost.

[0129] In some embodiments, please refer to Figures 3 to 6As shown, the lifting member 510 is a float 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 lifting member 510, wherein the elastic force of the second elastic member 540 is greater than the elastic force of the first elastic member 430, so that when the float bottle floats upward with the water level in the water storage tank 131 rising, the float bottle abuts against the second end of the connecting rod 520 and pushes the second end of the connecting rod 520 with the continuous upward floating of the float bottle, the connecting rod 520 rotates relative to the filter core assembly 200, so that 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 part 420; when the water storage tank 131 is short of water, the float bottle floats downward with the water level in the water storage tank 131 falling, the second end of the connecting rod 520 is in a free state at this time, at this time, the downward driving force of the connecting rod 520 to the valve body 410 through the top rod 530 is eliminated, so that the top rod 530 drives 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 part 420 to unblock the drain hole, that is, to open the drain hole, so that 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 surrounding water outlets 2211, so as to achieve the purpose of wetting the filter core 210.

[0130] In some embodiments, referring to Figure 12 and Figure 13 As shown, the outer bottom wall of the liquid containing groove 221 has an extension 2212, and the side wall close to 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 lifting member 510 contacts 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 part 420 is blocked at the drain hole.

[0131] For example, Figure 12As shown, the filter element assembly 200 also includes a limiting member 240. The bottom wall of the extension 2212 has a rotating groove 2213 with a bottom opening. The rotating shaft 522 is rotatably disposed in the rotating groove 2213. The limiting member 240 is disposed on the side of the rotating shaft 522 away from the extension 2212 and is detachably connected to the extension 2212. For example, the limiting member 240 is a limiting pressure plate. The limiting pressure plate is snapped, threaded, or magnetically connected to the top rod 530. In this way, when the second end of the connecting rod 520 moves upward with the float, the connecting rod 520 rotates relative to the extension 2212. The first end of the connecting rod 520 can push against the limiting pressure plate, so that the limiting pressure plate drives the top rod 530 to move downward, thereby causing the top rod 530 to drive the valve body 410 to move downward to close the drain hole; when the water storage tank 131 is short of water, the float moves downward. At this time, the second elastic element 540 drives the top rod 530 to push the valve body 410 upward under its own elastic force to open the drain hole. The top rod 530 drives the limiting pressure plate to push the first end of the connecting rod 520 upward, and the second end of the connecting rod 520 moves downward to reset the connecting rod 520.

[0132] In some embodiments, please refer to Figures 3 to 6 , Figure 14 As shown, the water storage pan 130 has a mounting boss 135, and the lifting component 510 has a relief groove 511 with a bottom opening. For example, the lifting component 510 is a hollow float bottle, and the float bottle cover is provided on the mounting boss 135. In this way, the mounting boss 135 can limit the circumferential movement of the float bottle, which can prevent the float bottle from moving circumferentially in the water storage tank 131 and affecting the reliability of the trigger linkage 520. It can be seen that the mounting boss 135 and the relief groove 511 are equivalent to a guide structure, which can guide the up and down floating of the float bottle, thereby improving the accuracy of the path when the float bottle floats up and down.

[0133] In addition, the drive mechanism 500 includes two connecting rods 520, which are located on both sides of the top rod 530 and are connected to the top rod 530. The ends of the two connecting rods 520 away from the top rod 530 are located above the lifting member 510. When the lifting member 510 moves upward in the vertical direction, the lifting member 510 pushes against 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. In this way, the force transmitted by the lifting member 510 can be evenly transmitted to the top rod 530 through the two connecting rods 520, thereby improving the smoothness of the movement of the valve body 410 driven by the top rod 530.

[0134] In some embodiments, please refer to Figures 14 to 16As shown, 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.

[0135] 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 lifting piece 510 floats up and down along the water level in the vertical direction, 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.

[0136] In the embodiments of the present application, first, the water shortage protection switch 600 is arranged, which can protect the humidifier 10 from water shortage; in addition, the water shortage protection switch 600 is arranged between the lifting piece 510 and the mounting boss 135, so that when the lifting piece 510 rises and falls along 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, which is simple in structure, low in cost, and can also improve the overall compactness of the humidifier 10, thereby achieving the purpose of lightening and miniaturization of the humidifier 10.

[0137] For example, as shown in Figs. 1 to 3, Figure 15 and Figure 16 As shown in Figs. 1 to 3, the water shortage protection switch 600 is mounted on the mounting boss 135, and the water shortage protection switch 600 is electrically connected with the motor 121 below it. The top of the water shortage protection switch 600 has a trigger part which can move in the vertical direction. When the water level in the water storage tank 131 continuously decreases, the groove bottom of the avoidance groove 511 contacts and pushes the trigger part downward. When the water storage tank 131 is in a water shortage state, the groove bottom of the avoidance groove 511 abuts against the trigger part. At this time, the motor 121 is in a power-off state. When the water storage tank 131 has water and continuously floats upward along with the rising of the water level in the water storage tank 131, the groove bottom of the avoidance groove 511 un-abuts against the trigger part, the trigger part moves upward, and the water shortage protection switch 600 is in an untriggered state. At this time, the motor 121 is in a power-on state, and the humidifier 10 can operate normally.

[0138] In order to further improve the accuracy of the up-and-down floating route of the lifting member 510, the mounting boss 135 is provided with a first guide portion, and the lifting member 510 is provided with a second guide portion matched with the first guide portion, when the lifting member 510 is in up-and-down movement, the first guide portion moves along the second guide portion, so that when the lifting member 510 floats up and down with the water level in the water storage tank 131, the lifting 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 lifting member 510 when it floats up and down, thereby improving the accuracy and reliability of the trigger link 520 and the water shortage protection switch 600.

[0139] 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, for example, in Figure 14 , 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, and the guide column 136 is arranged in the guide hole, so that the lifting member 510 floats up and down along the guide column 136.

[0140] In some embodiments, please refer to Figure 4 and Figure 6 The humidifier 10 further comprises a limiting screw 550, and the guide column 136 is provided with a threaded hole matched with the limiting screw 550, when the guide column 136 passes through the lifting member 510, the limiting screw 550 is screwed with the threaded hole at the top end of the guide column 136, so that the nut of the limiting screw 550 can limit the movement of the lifting member 510 in the vertical direction, so as to prevent the lifting member 510 from falling off the guide column 136.

[0141] In other embodiments, the structure of the link 520 and the structure of the lifting member 510 are different from those of the link 520 and the lifting member 510 provided in the above embodiments, please refer to Figures 17 to 20As shown in the embodiment of this application, the first end of the connecting rod 520 has an abutment portion 521 extending toward the valve body 410. The top rod 530 is connected between the abutment portion 521 and the valve body 410. The water storage pan 130 has a mounting base 134. The side wall of the connecting rod 520 has a rotating shaft 522, which is rotatably connected to the mounting base 134. The second end of the connecting rod 520 is detachably connected to the lifting member 510. When the lifting member 510 moves the second end of the connecting rod 520 downward in the vertical direction as the water level in the water storage tank 131 decreases, the connecting rod 520... The first end of the valve body 410 pushes the top rod 530 through the abutment part 521, so that the top rod 530 pushes the valve body 410 to move upward in the vertical direction, so that the sealing part 420 is removed from the drain hole and the drain hole is opened; when the lifting part 510 moves the second end of the connecting rod 520 upward in the vertical direction as the water level in the water storage tank 131 rises, 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 their own weight, so that the sealing part 420 blocks the drain hole, thereby closing the drain hole.

[0142] For example, such as Figures 17 to 20 As shown, when the second end of the connecting rod 520 is connected to the lifting member 510, the lifting 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 lifting member 510 in the humidifier 10 can be reduced, and there is no need to set up a second elastic member 540. This can further improve the structural compactness of the humidifier 10, reduce the number of parts, and reduce costs.

[0143] Additionally, regardless of whether the lifting component 510 is a float or a floating block, please refer to the following in some embodiments: Figure 4 , Figure 6 , Figure 18 as well as Figure 20 As shown, the end of the push rod 530 facing the connecting rod 520 has a second limiting structure 532. The second limiting structure 532 is configured to limit the upward movement of the push rod 530 in the vertical direction, while the first limiting structure 531 of the end of the push rod 530 facing the valve body 410 can limit the downward movement of the push rod 530 in the vertical direction, thereby preventing the push rod 530 from falling off the bottom of the liquid tank 221 and improving the reliability of the push rod 530 passing through the bottom of the liquid tank 221.

[0144] To further improve the overall compactness of the humidifier 10, please refer to... Figure 4 , Figure 6 , Figure 18 as well as Figure 20As shown, the bottom of the water storage tray 130 has a recessed space 137 towards the side of the water tank 300, the motor 121 is arranged in the recessed space 137, and the fan 122 is located below the motor 121 and connected with the output shaft of the motor 121, so that the overall structural compactness of the humidifier 10 can be improved.

[0145] In some embodiments, referring back to Figures 3 to 6 , Figures 8 to 10 As shown, the filter core assembly 200 includes a filter core upper cover 220 and a filter core lower cover 230, the filter core upper cover 220 and the filter core lower cover 230 are oppositely arranged and connected, the filter core upper cover 220 and the filter core lower cover 230 together enclose an annular cavity, the filter core lower cover 230 has an air inlet communicating with the annular cavity, and the filter core upper 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, and the filter core 210 is arranged on the airflow channel, so that the airflow blown by the air outlet grille 132 to the filter core assembly 200 can pass through the filter core 210 through the air inlet and flow out through the air outlet 2231, so as to evaporate the moisture on the filter core 210 in the air to increase the humidity of the air, thereby achieving the purpose of humidifying the air.

[0146] In some embodiments, referring back to Figures 8 to 10 As shown, the filter core lower cover 230 has a first wind blocking part 231, the filter core 210 has a submerged part 211, the submerged part 211 is located in the water storage tank 131, and the filter core lower cover 230 has a through hole at a position corresponding to the submerged part 211, so that the excess moisture on the filter core 210 can flow downward along the filter core 210 and flow into the water storage tank 131 through the submerged part 211, thereby avoiding the water on the filter core 210 from entering the inside of the humidifier main machine 100 to affect the service life of the internal components of the humidifier main machine 100.

[0147] 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.

[0148] 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.

[0149] 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.

[0150] 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.

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. In this way, 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 can be avoided, and thus the safety and reliability of the humidifier main machine 100 is improved, and the water drainage method is simple and convenient.

[0153] 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 the water in the water storage groove 131 is cleaned, 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.

[0154] It can be understood that the flow direction of the water discharged through the water outlet hole can be effectively guided through the drainage groove, so that the water in the water storage groove 131 can be cleaned without passing through the air outlet grille 132, the water passing through the air outlet grille 132 into the inside of the humidifier main machine 100 can be avoided, and the smoothness and safety and reliability of the water drainage of the water outlet hole can be improved.

[0155] 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.
