[0002] With the improvement of living standards, people have higher and higher requirements for indoor air quality and comfort. In addition to requiring the indoor air temperature to be within a suitable range, they also require the indoor air humidity to be within a suitable range. A humidifier can adjust the humidity of indoor air to meet the user's demand for indoor air comfort.

[0003] In related technologies, a humidifier generally includes a water tank and a humidifier main body. The humidifier main body is used to evaporate the liquid water in the water tank into gaseous water or atomize it into small droplets, thereby increasing the humidity of indoor air. When the water in the water tank is insufficient, the humidifier usually prompts the user through lights or sounds. The user needs to remove the lid of the water tank and then add water to the water tank. After adding water, the lid is sealed again.

[0004] However, the water adding process of the above water tank is relatively cumbersome, affecting the user experience. Utility Model Content

[0018] In this way, by arranging the first elastic reset member between the side wall of the first installation space and the connecting baffle, the first movable pin can be reset to the first position under the drive of the first elastic reset member to be in locking cooperation with the fixing groove.

[0019] In some embodiments, a through hole is formed in the side wall of the first installation space opposite to the first extending port, the first movable pin passes through the through hole, and a limiting portion is arranged at one end of the first movable pin far from the first extending port, and the limiting portion is in limiting cooperation with the end face of the through hole facing away from the first extending port.

[0020] In this way, the through hole provides guidance and limitation for the movement of the first movable pin.

[0021] In some embodiments, the driving assembly further includes a connecting rod, the first end of the connecting rod is connected to the float device, the second end of the connecting rod is in cooperation with the first movable pin, and the float device drives the first movable pin to perform telescopic movement through the connecting rod.

[0022] In this way, by arranging the connecting rod between the float device and the first movable pin, the movement of the float device can be transmitted to the first movable pin through the connecting rod, so as to realize the control of the switch assembly.

[0023] In some embodiments, a transmission cooperation surface is arranged on one side of the first movable pin facing the bottom wall of the water storage cavity, the transmission cooperation surface extends obliquely outward along the radial direction of the box body and away from the bottom wall of the water storage cavity, and the second end of the connecting rod is in sliding contact with the transmission cooperation surface.

[0024] In this way, when the connecting rod is driven by the float device, it can smoothly and stably push the first movable pin to realize the mechanical transmission between the float device and the first movable pin.

[0026] In this way, when the float body floats relative to the water level in the water storage cavity, it rotates around the pivot point of the connecting portion and the float bracket, thereby improving the sensitivity of the float device and realizing the transmission of driving force to the switch assembly.

[0027] In some embodiments, one end of the box cover opposite to the switch assembly is pivotally connected to the box body.

[0028] In this way, the flexibility of opening and closing the box cover is improved.

[0029] In some embodiments, one of the box body and the box cover is provided with a pivot hole, and the other is provided with a pivot shaft, and the pivot shaft is rotatably disposed in the pivot hole.

[0030] In this way, by providing the pivot shaft and the pivot hole matching the pivot shaft, the box cover can rotate smoothly around the pivot point with the box body, thereby realizing the opening and closing of the box cover.

[0031] In some embodiments, it further includes: an opening assist device disposed on the box body and in abutting cooperation with the box cover, the opening assist device being configured to drive the box cover to rotate relative to the box body to open the water filling port when the switch assembly unlocks the box cover.

[0033] In some embodiments, it further includes: the box body is provided with a second placement portion that defines a second installation space, the second installation space opening toward the box cover side along the height direction of the box body to form a second extension opening, and the opening assist device is telescopically disposed in the second installation space via the second extension opening to abut against the box cover.

[0034] In this way, it extends out through the second outlet opening by means of the opening assist device to abut and cooperate with the box cover, driving the box cover to rotate around the pivot point with the box body, realizing the automatic opening of the box cover and improving the automation degree of the water tank.

[0035] In some embodiments, the opening assist device includes: a second movable pin, which is telescopically arranged in the second installation space and abuts against the box cover; a second elastic reset member, which is sleeved on the second movable pin, with one end of the second elastic reset member connected to the second installation portion and the other end connected to the second movable pin.

[0036] In this way, by arranging the second elastic reset member, the second movable pin can extend out of the second outlet opening under the drive of the second elastic reset member, thereby driving the box cover to rotate around the pivot point with the box body, realizing the automatic opening of the box cover, facilitating the user to add water into the water tank, simplifying the water adding process, and effectively improving the user experience.

[0061] In order to make the above-mentioned objectives, features, and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without making creative efforts belong to the scope of protection of the present application.

[0062] A humidifier can adjust the humidity of indoor air to meet the user's demand for indoor air comfort. In the related art, a humidifier usually includes a water tank and a humidifier main body. The humidifier main body is used to evaporate the liquid water in the water tank into gaseous water or atomize it into small droplets, thereby increasing the humidity of indoor air. When the water tank is short of water, the humidifier usually prompts the user through lights or sounds. The user needs to remove the lid of the water tank and then add water to the water tank. After adding water, the lid is sealed again. However, the above-mentioned water adding process of the water tank is relatively cumbersome, affecting the user experience.

[0063] In view of this, the present application provides a water tank and a humidifying device. The water tank includes a tank main body, the tank main body has a water storage cavity for storing water and a water injection port communicating with the water storage cavity. A tank lid is provided on the water injection port, and the tank lid is movably connected to the tank main body to open or close the water injection port. A switch assembly is provided on one of the tank lid and the tank main body. Wherein, in the first position, the switch assembly is locked and cooperated with the other of the tank lid and the tank main body to close the water injection port; in the second position, the switch assembly is disengaged from the other of the tank lid and the tank main body to open the water injection port. The water tank further includes a driving assembly. The driving assembly is provided with a float device. The float device is located at the bottom of the water storage cavity and is used to float according to the water level in the water storage tank, and then drive the switch assembly to move. In this way, when the water tank is short of water, the driving assembly will automatically drive the switch assembly to disengage from the other of the tank lid and the tank main body to automatically open the water injection port, reminding the user that the water tank is short of water and facilitating the user to add water to the water tank, simplifying the water adding process and effectively improving the user experience.

[0064] The present application will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0065] See Figures 1 to 10 , the present application provides a water tank 10, which can be used for a device that consumes moisture to achieve its function. For example, the device can be an air treatment device such as a humidifier, or it can also be a cleaning device, or other types of devices. In this embodiment, the water tank 10 is used as an example for a humidifying device such as a humidifier.

[0066] Specifically, the water tank 10 may include a tank main body 100, a tank lid 200, a switch assembly 300, and a driving assembly 400.

[0067] The box body 100 may be cylindrical, square or irregular in shape. The box body 100 may define a water storage chamber 110, which may be used to hold water. A water injection port 120 connected to the water storage chamber 110 is provided at the top of the box body 100. When the water storage chamber 110 is short of water, water may be added to the water storage chamber 110 through the water injection port 120.

[0068] The box cover 200 is disposed on the water inlet 120 and is movably connected to the box body 100 to open or close the water inlet 120. For example, the box cover 200 can rotate, translate, or a combination of the two relative to the box body 100.

[0069] The switch assembly 300 is movably disposed on one of the box cover 200 and the box body 100, and moves between a first position and a second position, wherein in the first position, the switch assembly 300 is locked with the other of the box cover 200 and the box body 100, and in the second position, the switch assembly 300 is disengaged from the other of the box cover 200 and the box body 100; the drive assembly 400 includes a float device 410, which is disposed at the bottom of the water storage chamber 110, and the float device 410 is transmission-connected to the switch assembly 300, and the float device 410 is constructed to drive the switch assembly 300 to move when floating or sinking with the water level.

[0070] The box body 100 is the basic structure of the water tank 10, and the water storage chamber 110 is provided to effectively ensure the storage of water. The water inlet 120 provided at the top of the box body 100 is convenient for users to add water, ensure the smooth introduction of water flow, and reduce the problem of water splashing or overflow caused by improper water filling. In this way, the user experience is improved and the surrounding environment is ensured to be dry and clean.

[0071] It should be noted that the tank cover 200 is used to cover the water inlet 120, providing an effective seal for the water inlet 120, preventing dust, insects and other external pollutants from entering the water storage chamber 110, thereby ensuring the purity of the water in the water storage chamber 110. In addition, the movable connection between the tank cover 200 and the tank body 100 makes the opening and closing operations of the tank cover 200 quick, thereby enhancing the convenience of use of the water tank 10.

[0072] Furthermore, when the water storage chamber 110 is short of water, the float device 410 drives the switch assembly 300 to move to the second position, and the switch assembly 300 disengages from the other of the box cover 200 and the box body 100, so that the box cover 200 is automatically opened, and the water injection port 120 is in an open state, so as to prompt the user to perform a water filling operation. At this time, the user can inject water into the water storage chamber 110 along the water injection port 120. After the water filling is completed, the user can push the box cover 200 toward the box body 100 to close the water injection port 120. When the switch assembly 300 moves to the first position, the switch assembly 300 can be firmly locked with the other of the box cover 200 and the box body 100, ensuring that the water tank 10 remains sealed when the water is not added, and preventing the water injection port 120 from accidentally opening or leaking. In this way, the user does not need to manually disassemble and assemble the box cover 200, which enhances the convenience of use of the water tank 10.

[0073] It should also be noted that, in order to realize the automatic opening of the box cover 200 when there is a lack of water in the water storage chamber 110 (that is, to realize driving the switch assembly 300 to move to the second position), the water tank 10 is also provided with a driving assembly 400, and the driving assembly 400 has a float device 410 that is transmission-connected to the switch assembly 300. The float device 410 utilizes the buoyancy principle to float up and down with the change of the water level in the water storage chamber 110, thereby driving the switch assembly 300 to move. That is to say, the scheme of this embodiment can convert the buoyancy of the float device into the power for the movement of the switch assembly 300. In this way, when there is a lack of water in the water tank 10, the float device 410 will float relative to the water storage chamber 110, thereby driving the switch assembly 300 to disengage from the other of the tank cover 200 and the tank body 100, so as to automatically open the water filling port 120, reminding the user that there is a lack of water in the water tank 10 while making it convenient for the user to add water to the water tank 10. Compared with the water tank in the related art, the water tank 10 provided in the embodiment of the present application does not require the user to manually disassemble or open and close the tank cover 200, thereby simplifying the water adding process and effectively improving the user experience.

[0074] See also Figures 1 to 3 In the embodiment of the present application, one of the box cover 200 and the box body 100 is provided with a locking mating structure, and the other is provided with a first placement portion 500. The switch assembly 300 can be movably disposed in the first placement portion 500 and locked or disengaged with the locking mating structure.

[0075] In a specific implementation, in order to realize the switching of the switch assembly 300 between the first position and the second position, one of the box cover 200 and the box body 100 is provided with a locking matching structure. Thus, when the switch assembly 300 is in the first position, the switch assembly 300 is locked with the locking matching structure so that the box cover 200 closes the water filling port 120, thereby enhancing the sealing performance of the water tank 10 when the water filling port 120 is closed, effectively preventing accidental leakage of water and intrusion of external pollutants, and improving the safety and reliability of the water tank 10.

[0076] On the other hand, in order to install the switch assembly 300, a first placement portion 500 is provided in the other one of the lid 200 and the main body 100 of the box. The switch assembly 300 is movably installed in the first placement portion 500, which can achieve precise response and smooth movement of the switch assembly 300 when the water level changes, making the automatic control process of the water tank 10 more efficient and accurate. When the water level drops, the float device 410 can drive the switch assembly 300 to smoothly move in the first placement portion 500, so that the switch assembly 300 is disengaged from the locking and mating structure, causing the lid 200 to automatically open, prompting the user that the water tank 10 is short of water, and facilitating the user to add water into the water storage cavity 110 along the water injection port 120.

[0077] See Figure 3 , in the embodiment of the present application, the cavity wall of the water storage cavity 110 is recessed radially outward along the main body 100 of the box to form a fixing groove 111, and the fixing groove 111 constitutes the locking and mating structure.

[0078] Specifically, when a part of the switch assembly 300 is inserted into the fixing groove 111 provided on the cavity wall of the water storage cavity 110 (that is, when the switch assembly 300 is locked and mated with the fixing groove 111), the lid 200 can be tightly locked with the main body 100 of the box, effectively preventing accidental leakage of water and intrusion of external pollutants, and ensuring the purity and safety of the water quality in the water storage cavity 110.

[0079] In addition, by providing the fixing groove 111, the water tank 10 can achieve the locking function of the switch assembly 300 without setting an additional locking device. In this way, the manufacturing process and the overall structure are simplified, and the manufacturing cost is reduced.

[0080] See Figure 3 , in the embodiment of the present application, the first placement portion 500 defines a first installation space 510, and the first installation space 510 has a first extension opening 520 opposite to the fixing groove 111. At least part of the structure of the switch assembly 300 can be telescoped through the first extension opening 520 to extend into or disengage from the fixing groove 111 through the first extension opening 520 under the drive of the drive assembly 400.

[0081] Among them, the first installation space 510 serves as a carrier for the switch assembly 300 to provide an accommodation space for the switch assembly 300. Placing the switch assembly 300 in the first installation space 510 ensures the stability and reliability of the switch assembly 300 during operation, and avoids misalignment or damage caused by external factors.

[0082] In this embodiment, the relative positions of the first outlet 520 and the fixing groove 111 ensure that the switch assembly 300 can accurately extend into or disengage from the fixing groove 111 through the first outlet 520 under the drive of the drive assembly 400.

[0083] Furthermore, at least part of the structure of the switch assembly 300 can achieve a telescopic function through the first outlet 520, ensuring the smoothness of the movement path of the switch assembly 300 between the first position and the second position.

[0084] See Figure 3 and Figure 9 , in the embodiment of the present application, the switch assembly 300 includes a first movable pin 310. The first movable pin 310 is telescopically arranged in the first installation space 510, and the first movable pin 310 is in transmission cooperation with the float device 410.

[0085] It should be noted that, as a transmission element, the telescopic design of the first movable pin 310 enables the first movable pin 310 to flexibly adjust its position in different states of the water tank 10. This ensures that the switch assembly 300 can quickly respond to changes in external conditions (i.e., changes in the water level in the water storage cavity 110), improving the flexibility and reliability of the switch assembly 300. When the float device 410 rises and falls with the water level in the water storage cavity 110, it can drive the first movable pin 310 to perform corresponding telescoping relative to the first installation space 510. Through the transmission cooperation between the float device 410 and the first movable pin 310, the movement of the switch assembly 300 between the first position and the second position is realized, thereby controlling the locking and unlocking between the lid 200 and the main body 100 of the box.

[0086] See Figure 3 and Figure 9 , in the embodiment of the present application, the first movable pin 310 includes a pin body 311 and a connecting baffle 312. The connecting baffle 312 is arranged on the side wall of the pin body 311. The switch assembly 300 further includes a first elastic reset member 320. The first elastic reset member 320 is sleeved on the pin body 311. One end of the first elastic reset member 320 is connected to the connecting baffle 312, and the other end is connected to the side wall of the first installation space 510 opposite to the first outlet 520.

[0087] Specifically, the first elastic reset member 320 is used to realize the elastic reset function of the switch assembly 300. The first elastic reset member 320 can be a spring, which is of course not limited in this embodiment. The first elastic reset member 320 is sleeved on the pin body 311, one end of which is tightly connected to the connecting baffle 312, and the other end is fixed to the side wall of the first installation space 510 opposite to the first extension port 520. In this way, when the push of the float device 410 acts on the first movable pin 310, the first movable pin 310 can smoothly disengage from the fixing groove 111, and the first elastic reset member 320 is in a compressed state; and when the float device 410 no longer pushes the first movable pin 310, the first elastic reset member 320 drives the first movable pin 310 to reset to the first position through its elastic action, so as to lock and cooperate with the fixing groove 111.

[0088] Among them, the first installation space 510 and the connecting baffle 312 provide stable support and restriction for the first elastic return member 320, ensuring that the first elastic return member 320 is always located between the side wall of the first installation space 510 opposite to the first extension port 520 and the connecting baffle 312, effectively preventing the first elastic return member 320 from loosening or falling off during long-term use, thereby extending the service life of the switch assembly 300.

[0089] See also Figure 3 In the embodiment of the present application, a through hole 511 is provided on the side wall of the first installation space 510 opposite to the first extension port 520, and the first movable pin 310 is passed through the through hole 511. A limiting portion 313 is provided on the end of the first movable pin 310 away from the first extension port 520, and the limiting portion 313 is limitedly matched with the end face of the through hole 511 facing away from the first extension port 520.

[0090] The through hole 511 provides guidance and position limiting for the first movable pin 310. By allowing the first movable pin 310 to pass through the through hole 511, it is ensured that the first movable pin 310 maintains a straight track during movement, avoiding inaccurate operation or damage caused by deviation or shaking, and improving the reliability and stability of the switch assembly 300.

[0091] In addition, the limiting cooperation between the limiting portion 313 and the end surface of the through hole 511 further enhances the limiting effect of the first movable pin 310. When the first movable pin 310 moves to the extreme position (for example, the first movable pin 310 moves to the second position), the limiting portion 313 will contact the end surface of the through hole 511 facing away from the first extension port 520, thereby preventing the first movable pin 310 from continuing to move. In this way, the switch assembly 300 is protected from possible damage caused by excessive movement, ensuring the accuracy and consistency of the switch action.

[0092] See alsoFigure 3 , Figure 4 and Figure 6 , in the embodiment of the present application, the driving assembly 400 further includes a connecting rod 420. The first end of the connecting rod 420 is connected to the float device 410, and the second end of the connecting rod 420 is engaged with the first movable pin 310. The float device 410 drives the first movable pin 310 to perform telescopic movement through the connecting rod 420.

[0093] Specifically, since the float device 410 is located at the bottom of the water storage cavity 110, there will be problems such as space limitation or poor transmission path when driving the first movable pin 310. Therefore, an intermediate transmission element, the connecting rod 420, is provided between the float device 410 and the first movable pin 310. The transmission efficiency and stability between the float device 410 and the first movable pin 310 are enhanced through the connecting rod 420. Ensure that the movement of the float device 410 can be efficiently transmitted to the first movable pin 310, thereby realizing the control of the switch assembly 300.

[0094] In addition, using the connecting rod 420 as the intermediate transmission element between the float device 410 and the first movable pin 310, compared with complex mechanical transmission mechanisms or electronic control systems, the connecting rod 420 reduces the manufacturing cost and maintenance difficulty of the driving assembly 400 with its simple and reliable characteristics. And the structure of the connecting rod 420 helps to reduce the volume and weight of the water tank 10 and improve the space utilization rate of the water storage cavity 110.

[0095] Furthermore, a guiding groove 112 can be provided on the inner wall of the water storage cavity 110. The connecting rod 420 is located in the guiding groove 112 and slides up and down relative to the guiding groove 112 under the drive of the float device 410. Thus, the guiding groove 112 provides guiding and limiting for the movement of the connecting rod 420, improving the reliability and stability of the connecting rod 420.

[0096] See Figure 3 and Figure 9 , in the embodiment of the present application, a transmission mating surface 314 is provided on one side of the first movable pin 310 facing the bottom wall of the water storage cavity 110. The transmission mating surface 314 extends obliquely outward along the radial direction of the box main body 100 and away from the bottom wall of the water storage cavity 110. The second end of the connecting rod 420 is in sliding abutment with the transmission mating surface 314.

[0097] It should be noted that the second end of the connecting rod 420, as the component in contact with the transmission mating surface 314, can perform sliding abutment along the inclined path of the transmission mating surface 314. Ensure that when the connecting rod 420 is driven by the float device 410, the connecting rod 420 can smoothly and stably push the first movable pin 310 to achieve the purpose of mechanical transmission.

[0098] In addition, by setting the transmission mating surface 314, on the one hand, the efficiency and accuracy of mechanical transmission between the connecting rod 420 and the first movable pin 310 are improved, and on the other hand, the stability and reliability of the first movable pin 310 are enhanced, enabling the switch assembly 300 to maintain a good working state during operation.

[0099] Refer to Figure 4 , in the embodiment of the present application, the float device 410 includes a float bracket 411 fixedly arranged on the bottom wall of the water storage cavity 110; the float device 410 further includes a float body 412, the density of the float body 412 is lower than the density of water, the float body 412 includes a floating part 4121 and a connecting part 4122, the connecting part 4122 has a first end and a second end opposite to each other along its own length direction, the first end is in abutting cooperation with the connecting rod 420, the second end is connected to the floating part 4121, and the part of the connecting part 4122 between the first end and the second end is pivotally connected to the float bracket 411.

[0100] Among them, the float bracket 411 is firmly installed at the bottom of the water storage cavity 110, ensuring a stable supporting effect in various working environments.

[0101] Furthermore, the float body 412 is used to float flexibly in the water storage cavity 110 according to the water level and transmit the driving force to the connecting rod 420. The density of the float body 412 is lower than the density of water, so that the float body 412 can float naturally on the water surface without applying external force. The float body 412 is further divided into a floating part 4121 and a connecting part 4122, and the floating part 4121 and the connecting part 4122 are connected to each other, jointly forming an integral body that can float flexibly and transmit the driving force to the connecting rod 420.

[0102] Specifically, when implemented, the floating part 4121 is the part of the float body 412 that contacts the water body and bears the buoyancy, and can respond to the change of the water level. The connecting part 4122 is used to connect the floating part 4121 and the float bracket 411, and is used for abutting cooperation with the connecting rod 420. The connecting part 4122 is provided with a first end and a second end opposite to each other along its length direction, wherein the first end forms an abutting cooperation with the connecting rod 420, so that when the water level changes, the float body 412 can convert the change of buoyancy into a driving force through the connecting rod 420, and further drive the switch assembly 300 to perform corresponding movements in the first installation space 510.

[0103] It should be noted that the pivotal connection between the connecting part 4122 and the float bracket 411 ensures the free floating of the float body 412 in the water, and also enables the float body 412 to rotate around the pivot point when the water level changes, thereby improving the sensitivity of the float device 410.

[0104] Refer to Figure 5, in the embodiment of the present application, one end of the lid 200 opposite to the switch assembly 300 is pivotally connected to the box body 100.

[0105] In order to achieve flexible opening and stable closing of the lid 200, a pivotal connection is also adopted between the lid 200 and the box body 100. In this way, it is ensured that the lid 200 can rotate smoothly around the pivot point during the opening process. In addition, when the lid 200 is closed, it can closely fit the edge of the box body 100 to form an effective seal.

[0106] See Figure 5 , in the embodiment of the present application, one of the box body 100 and the lid 200 is provided with a pivot hole 130, and the other is provided with a pivot shaft 210. The pivot shaft 210 is rotatably arranged in the pivot hole 130.

[0107] In specific implementation, by setting the pivot shaft 210 and the pivot hole 130 matching the pivot shaft 210, it is ensured that the pivot shaft 210 can be smoothly inserted and freely rotate in the pivot hole 130, maintaining sufficient stability and durability.

[0108] When the lid 200 is connected to the box body 100, the pivot shaft 210 is accurately inserted into the pivot hole 130. At this time, the lid 200 can smoothly rotate around the pivot shaft 210, thereby realizing the opening and closing of the lid 200. Moreover, through the close cooperation of the pivot hole 130 and the pivot shaft 210, when the lid 200 is closed, it can maintain a stable sealed state with the box body 100, effectively preventing accidental leakage of water and intrusion of external pollutants.

[0109] See Figure 5 , in the embodiment of the present application, the water tank 10 further includes an opening assist device 600. The opening assist device 600 is arranged on the box body 100 and is in abutting cooperation with the lid 200. The opening assist device 600 is configured to drive the lid 200 to rotate relative to the box body 100 to open the water filling port 120 when the switch assembly 300 unlocks the lid 200.

[0110] Among them, the opening assist device 600 is in abutting cooperation with the lid 200, ensuring that the opening assist device 600 can accurately apply force to the lid 200 during operation, avoiding opening failure caused by the position deviation or looseness of the opening assist device 600.

[0111] It should be noted that when the switch assembly 300 moves to the second position under the drive of the connecting rod 420, the first movable pin 310 is disengaged from the fixing groove 111, and the lid opening assisting device 600 drives the lid 200 to rotate relative to the box body 100 by using the energy stored inside, realizing the opening of the lid 200 and making the water injection port 120 in an open state. In this way, it effectively reminds the user that water needs to be injected into the water storage cavity 110. When the user adds water to the water storage cavity 110, there is no need to disassemble the lid 200. The user can add water into the water storage cavity 110 along the water injection port 120. After adding water, the user can push the lid 200 to rotate around the pivot point with the box body 100 to close the lid 200, improving the operation convenience, simplifying the water adding process, and effectively improving the user experience.

[0112] See Figure 5 , in the embodiment of the present application, the box body 100 is provided with a second placement part 140, the second placement part 140 defines a second installation space 141, the second installation space 141 is open along the height direction of the box body 100 and towards the side of the lid 200 to form a second extension opening 142, and the lid opening assisting device 600 is telescopically arranged in the second installation space 141 via the second extension opening 142 to abut against the lid 200.

[0113] In order to install the lid opening assisting device 600 on the box body 100, the second placement part 140 is provided with a second installation space 141 for accommodating the lid opening assisting device 600. And, in order to realize the abutting cooperation between the lid opening assisting device 600 and the lid 200, a second extension opening 142 is opened on the second installation space 141, so that the lid opening assisting device 600 can extend or retract relative to the second extension opening 142 to abut against the lid 200.

[0114] Specifically, when the lid 200 needs to be opened, the lid opening assisting device 600 can respond quickly, extend out from the second installation space 141 via the second extension opening 142, and drive the lid 200 to rotate around the pivot point with the box body 100 through the abutting cooperation with the lid 200, realizing the automatic opening of the lid 200. In this way, the automation degree of the water tank 10 is improved, and the user does not need to manually disassemble the lid 200 to add water to the water storage cavity 110, improving the user experience.

[0115] See Figure 5 and Figure 10 , in the embodiment of the present application, the lid opening assisting device 600 includes a second movable pin 610, the second movable pin 610 is telescopically arranged in the second installation space 141, and the second movable pin 610 abuts against the lid 200; the lid opening assisting device 600 further includes a second elastic reset member 620, the second elastic reset member 620 is sleeved on the second movable pin 610, one end of the second elastic reset member 620 is connected to the second placement part 140, and the other end is connected to the second movable pin 610.

[0116] Among them, the second movable pin 610 is telescopically installed in the second installation space 141. When the first movable pin 310 is disengaged from the fixing groove 111 under the drive of the connecting rod 420, the second movable pin 610 extends out of the second outlet 142 under the elastic drive of the second elastic reset member 620 to form an effective abutment with the lid 200, thereby driving the lid 200 to rotate around the pivot point with the box body 100 to realize the automatic opening of the lid 200.

[0117] It can be understood that the second elastic reset member 620 can be a spring. The second elastic reset member 620 is sleeved on the second movable pin 610, and one end thereof is firmly connected to the second placement portion 140, and the other end is connected to the second movable pin 610. In this way, elastic support and reset functions are provided for the telescopic movement of the second movable pin 610.

[0118] When the lid 200 is in the closed state, at this time, the second elastic reset member 620 is in a compressed state and stores corresponding elastic potential energy. When the first movable pin 310 is disengaged from the fixing groove 111 under the drive of the connecting rod 420, the second elastic reset member 620 drives the second movable pin 610 to extend out of the second outlet 142 through the elastic potential energy stored by it, so that the second movable pin 610 contacts the lid 200 and assists in opening the lid 200. In this way, the automatic operation of the lid opening assisting device 600 is ensured, and the reliability of the lid opening assisting device 600 is improved.

[0119] See Figure 11 , on the basis of the above embodiments, the embodiment of the present application further provides a humidifying device 1. The humidifying device 1 can be a household humidifier or an industrial humidifying device. The humidifying device 1 can include a device main body 20 and the water tank 10 provided in any one of the above embodiments.

[0120] Among them, the device main body 20 can include a water tank interface and a humidifying unit. The humidifying unit can include at least one of an ultrasonic atomizer and a humidifying filter element. The water tank 10 is connected to the device main body 20 through the water tank interface. The water in the water tank 10 is atomized by the humidifying unit and discharged through the mist outlet 220 to achieve the effect of increasing the humidity of the surrounding environment.

[0121] The humidifying device 1 of the embodiment of the present application can effectively prompt the user to add water to the water tank 10 by setting the water tank 10 in the above embodiment, simplifies the water adding process, and effectively improves the user experience.
