[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0042] First, those skilled in the art should understand that these implementations are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0043] Secondly, it should be noted that in the description of the present application, terms such as "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present application.

[0044] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present disclosure. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0046] A humidifier can adjust the humidity of indoor air to meet the user's demand for indoor air comfort. A humidifier usually includes a water tank, a fan and other components. The fan is used to form airflow. The water in the water tank can evaporate or atomize through natural volatilization, a heating unit or an ultrasonic unit, thereby humidifying the airflow passing through the humidifier and increasing the humidity of the airflow. A filter element is provided in the water tank, which can filter and adsorb impurities in the humidification water in the water tank to ensure the cleanliness of the humidification water. The filter element needs to be taken out of the water tank regularly for cleaning.

[0047] However, since the filter element has the ability to absorb water, the current humidifier will drip water when the filter element is taken out of the water tank, which can easily wet the table and floor near the humidifier. In addition, when the humidifier is not in use, the filter element adsorbed with water is prone to mold and must be cleaned again when used again, otherwise it will affect the health of users in the humidified environment. Repeated cleaning of the filter screen affects the user experience.

[0048] In order to solve the above problems, the embodiment of the present application provides a humidifying device, which can be unfolded and folded by designing the filter element installation and supporting structure. When the user needs to remove the filter element, the filter element can be folded in the water tank to discharge most of the water in the filter element and leave it in the water tank, so that when the folded filter element is taken out of the water tank, dripping of the filter element can be prevented. In addition, when the humidifying device is not in use, the filter element can be compressed to drain the water to avoid mold on the filter element, thereby improving the user experience.

[0049] To facilitate understanding, the application scenario of the humidification device provided in the embodiment of the present application is first described.

[0050] The humidifying device provided in the embodiment of the present application can be used in indoor occasions where air humidity adjustment is required. The humidifying device can be powered by an external power supply, or it can be powered by its own power supply. The embodiment of the present application does not make specific limitations on this. The humidifying device in the embodiment of the present application can be a humidifier, or it can be a humidifying module used in other equipment such as air conditioners and air handling equipment. In addition, the liquid added to the interior of the humidifying device in the embodiment of the present application for generating water vapor or mist can be pure water, or an aqueous solution mixed with additives such as spices, bactericides, essential oils, etc. The embodiment of the present application does not make specific limitations on this, and it will be collectively referred to as "water" below, and no specific examples will be given.

[0051] Figure 1 This is an exploded view of the humidification device provided in an embodiment of the present application. Figure 2 This is a cross-sectional view of the wire passing assembly in the water tank assembly of the humidification device provided in an embodiment of the present application. Figure 3 A schematic diagram of the folded state of the filter element of the filter assembly in the humidification device provided in an embodiment of the present application.

[0052] like Figures 1 to 3 As shown, the embodiment of the present application provides a humidifying device, which includes a device body 100, a water tank assembly 200 and a filter assembly 300. The device body 100 is connected to the water tank assembly 200, and the filter assembly 300 is arranged in the water tank assembly 200. The water tank assembly 200 can store water required for humidification, and the filter assembly 300 can filter and adsorb impurities in the water tank assembly 200.

[0053] The filter assembly 300 includes a support 310, an upper cover 320 and a filter element 330. The upper cover 320 is movably connected to the support 310. The first end of the filter element 330 is connected to the support 310, and the second end of the filter element 330 is connected to the upper cover 320. The filter element 330 is a foldable filter element 330. When the upper cover 320 moves relative to the support 310, the filter element 330 can be folded or unfolded.

[0054] It is understandable that the first end of the filter element 330 remains in a position relative to the bracket 310 because it is connected to the bracket 310, while the second end of the filter element 330 is connected to the upper cover 320, and its position relative to the bracket 310 changes with the movement of the upper cover 320. When the filter element 330 is folded, the upper cover 320 drives the second end of the filter element 330 to move toward the first end of the filter element 330, the height of the filter element 330 is reduced, and the filter element 330 is compressed so that the water in the filter element 330 is discharged; when the filter element 330 is unfolded, the upper cover 320 drives the second end of the filter element 330 to move away from the first end of the filter element 330, and the height of the filter element 330 is increased. At this time, the filter element 330 can absorb water and filter.

[0055] Exemplarily, the moving direction of the upper cover 320 is defined as the X direction, and the X direction is the height direction of the filter element 330. The filter element 330 can be moved along the X direction to be folded or unfolded. The filter element 330 may include a plurality of filter segments connected in sequence, and there is an angle between adjacent filter segments. When the filter element 330 is folded or unfolded, the plurality of filter segments are folded and unfolded, wherein when the filter element 330 is folded, the angle between adjacent filter segments decreases, and when the filter element 330 is unfolded, the angle between adjacent filter segments increases. In this way, the filter element 330 can be prevented from being damaged during repeated folding and unfolding, thereby increasing the service life of the filter element 330.

[0056] It should be noted that, in the humidifying device provided in the embodiment of the present application, a relatively movable bracket 310 and upper cover 320 are provided, and the bracket 310 and the upper cover 320 simultaneously support and fix the filter element 330. When the filter element 330 needs to be removed from the water tank assembly 200, the filter element 330 can be compressed by moving the upper cover 320 to fold the filter element 330, thereby squeezing the water in the filter element 330 out of the water tank assembly 200, and then the folded filter element 330 is taken out from the water tank assembly 200 to prevent the filter element 330 from dripping when being taken out, thereby improving the user experience.

[0057] In addition, when the humidifier is not in use, before the humidifier is stored, the water therein can be quickly discharged by compressing the filter element 330, so that the filter element 330 can be quickly dried to facilitate the rapid storage of the humidifier.

[0058] First, the specific structure of the bracket 310 and the specific matching method between the upper cover 320 and the bracket 310 are described in detail below.

[0059] Figure 4 This is a schematic diagram of the connection between the filter element and the upper cover and the bottom cover in the humidification device provided in an embodiment of the present application. Figure 5 An exploded view of a filter assembly in a humidification device provided in an embodiment of the present application.

[0060] Please refer to Figures 2 to 5 In a possible implementation, the bracket 310 may include a bottom cover 311 and a guide member 312, and the end of the guide member 312 is connected to the bottom cover 311. The first end of the filter element 330 is connected to the bottom cover 311. The upper cover 320 is movably connected to the guide member 312, and the upper cover 320 is configured to move along the length direction of the guide member 312.

[0061] It can be understood that the bottom cover 311 is located below the filter element 330, the upper cover 320 is located above the filter element 330, and the guide member 312 is located on the side of the filter element 330. The upper cover 320 and the bottom cover 311 can provide good support at both ends of the filter element 330, and the guide member 312 can provide guidance for the movement of the upper cover 320 to ensure the smoothness of the folding or unfolding of the filter.

[0062] Exemplarily, when the filter assembly 300 is placed in a water tank for normal use, the bottom cover 311 abuts against the bottom wall of the water tank, the guide member 312 extends along the X direction, that is, the guide member 312 extends along the vertical direction, and the upper cover 320 is located at the end of the filter element 330 facing the water tank opening.

[0063] It should be noted that abutment can be provided on the bottom wall of the water tank, and the abutment protrudes relative to the bottom wall of the water tank. When the filter assembly 300 is placed in the water tank, the bottom cover 311 can abut against the abutment, and the shape of the abutment can match the shape of the bottom cover 311. The abutment can support and position the bottom cover 311.

[0064] In some embodiments, the guide member 312 may include a guide rod 312a, and the upper cover 320 may be provided with a guide hole, and the guide rod 312a is passed through the guide hole, thereby avoiding jamming when the guide member 312 and the upper cover 320 move relative to each other, thereby improving the smoothness of movement of the upper cover 320.

[0065] It is understandable that the cross-sectional shape of the guide hole matches the cross-sectional shape of the guide rod 312a. The cross-sectional size of the guide hole may be equal to or slightly larger than the cross-sectional size of the guide rod 312a.

[0066] For example, the guide hole may be a round hole, and the guide rod 312a may be a cylindrical rod. Alternatively, the guide hole may be a square hole, and the guide rod 312a may be a square rod. The specific cross-sectional shapes of the guide hole and the guide rod 312a are not limited in the present embodiment.

[0067] For example, the guide rod 312a can be directly inserted into the guide hole. Alternatively, a sliding bearing can be provided on the guide rod 312a or the guide hole to improve the smoothness of the upper cover 320 moving along the guide rod 312a. Alternatively, a ball bearing can be provided in the guide hole, and when the upper cover 320 moves along the guide rod 312a, the ball bearing can roll along the surface of the guide rod 312a to reduce friction and improve the smoothness of the upper cover 320 moving along the guide rod 312a.

[0068] It should be noted that the guide member 312 can also adopt a sliding groove structure to cooperate with the upper cover 320. The sliding groove extends in the vertical direction, and the upper cover 320 slides along the sliding groove to achieve folding or unfolding of the filter element 330. The embodiments of the present application are not described in detail here.

[0069] Please continue to refer to Figures 2 to 5 In some embodiments, the filter assembly 300 may further include an elastic member 340, which is sleeved on the guide rod 312a, with a first end of the elastic member 340 abutting against the bottom cover 311, and a second end of the elastic member 340 abutting against the upper cover 320. The elastic member 340 is configured to apply an elastic force to the upper cover 320 in a direction away from the bottom cover 311.

[0070] It is understandable that when the filter is placed in the water tank assembly 200 for normal use, the elastic force of the elastic member 340 can be used to maintain the upper cover 320 at the end of the guide member 312 away from the bottom cover 311, thereby relying on the elastic force of the elastic member 340 to keep the filter element 330 in the expanded state.

[0071] For example, the elastic member 340 can be a spring, which is sleeved on the guide rod 312a, and the guide rod 312a is located in the compression and rebound of the spring to provide guidance. When the filter assembly 300 needs to be taken out of the water tank assembly 200, the upper cover 320 is first pressed down so that the lower cover compresses the filter screen to fold it. In this process, the elastic force of the elastic member 340 is overcome. When the filter assembly 300 is put back into the water tank assembly 200, the upper cover 320 can drive the filter screen to unfold through the elastic force of the spring.

[0072] In some embodiments, a fixing portion 3111 is provided at the edge of the bottom cover 311, and the fixing portion 3111 has a fixing groove 3112, and the end of the guide rod 312a is inserted into the fixing groove 3112 and bonded to the fixing groove 3112, thereby improving the reliability of the connection between the guide rail and the bottom cover 311.

[0073] For example, the fixing portion 3111 may be integrally formed with the main structure of the bottom cover 311. The fixing portion 3111 may be arranged to protrude from the edge of the bottom cover 311, thereby preventing the filter element 330 from interfering with the guide member 312 when folding.

[0074] It should be noted that the end of the guide rod 312a can also be connected to the fixing portion 3111 via fasteners such as bolts, or welded, which is not specifically limited in the embodiment of the present application.

[0075] In some embodiments, the filter assembly 300 may further include a stopper 350, which is connected to one end of the guide member 312 away from the bottom cover 311. When the filter element 330 is unfolded, the upper cover 320 abuts against the stopper 350, thereby limiting the movement of the upper cover 320 relative to the guide member 312 and preventing the upper cover 320 from falling off the guide member 312.

[0076] It is understandable that when the filter element 330 is in the unfolded state, the upper box cover of the bottom cover 311 is respectively located at both ends of the guide member 312, and the height of the filter screen is similar to the height of the guide member 312. The stopper 350 can be connected to the top of the wire member. The cross-sectional size of the stopper 350 can be larger than the cross-sectional size of the guide hole on the upper cover 320.

[0077] Exemplarily, the limiting member 350 can be a limiting nut. When assembling the bracket 310 and the upper cover 320, the elastic member 340 can be firstly placed on the guide rod 312a, and then the upper cover 320 can be placed on the guide rod 312a. Thereafter, the limiting member 350 can be screwed to the top thread of the guide rod 312a, thereby limiting the upper cover 320.

[0078] In some embodiments, there may be a plurality of guide members 312, and the plurality of guide members 312 are parallel to each other. The plurality of guide members 312 are arranged at intervals around the filter element 330, so that the bracket 310 has a good supporting effect on the filter screen.

[0079] It is understandable that the filter element 330 may be an annular filter element 330. The upper cover 320 may be an annular plate-like structure. The bottom cover 311 may be an annular plate-like structure. A plurality of guide members 312 surround the periphery of the filter screen, so that when the filter screen is compressed and folded through the upper cover 320, each position of the filter screen can be fully compressed and drained, thereby improving the compression and drainage effect of the filter screen to prevent the filter screen from dripping when the water tank assembly 200 is taken out.

[0080] The structure of the water tank assembly 200 is described in detail below.

[0081] Figure 6 An exploded view of a water tank assembly in a humidification device provided in an embodiment of the present application.

[0082] Please refer to Figure 6 , and combined with Figures 1 to 4 In a possible implementation, the water tank assembly 200 may include a box body 210, and the filter assembly 300 is located in the box body 210. The upper cover 320 is located on the side of the filter element 330 facing the top of the box body 210. When the water tank assembly 200 is opened, it is convenient for the user to push the upper cover 320 downward from the opening above the water tank, thereby improving the convenience of operation when the filter element 330 is folded.

[0083] It can be understood that when the bracket 310 is placed in the water tank assembly 200, the height of the bracket 310 can be higher than the height of the box body 210, that is, when the filter element 330 is in the expanded state, the filter element 330 can partially extend to the outside of the box body 210. In this way, when the humidifier is in use, the filter element 330 can help the volatilization of water, which is beneficial to improve the humidification efficiency of the humidifier.

[0084] In some embodiments, the water tank assembly 200 may further include a float 220 and a float bracket 230, wherein the float bracket 230 is connected to the tank body 210, and the float 220 is sleeved on the float bracket 230. The filter element 330 may be arranged around the float 220, thereby increasing the filtering area of ​​the filter element 330 for the humidification water in the water tank.

[0085] It is understandable that the annular filter element 330 , the upper cover 320 and the bottom cover 311 can avoid the float 220 when the filter element 330 is compressed and the filter assembly 300 is removed.

[0086] Figure 7 This is an exploded view of the device body in the humidification device provided in an embodiment of the present application.

[0087] Please refer to Figure 7 , and combined with Figures 1 to 4 In some embodiments, the device body 100 may include a housing 110, a fan and a fan bracket 120, the fan and the fan bracket 120 are arranged in the housing 110, the fan bracket 120 is connected to the housing 110, and the fan is connected to the fan bracket 120. The housing 110 is connected to the water tank assembly 200 to improve the convenience of disassembly and assembly between the device body 100 as a whole and the water tank assembly 200.

[0088] The air inlet side of the fan faces the box body 210, and the fan is used to generate airflow. A switch unit 160 may be provided on the fan bracket 120, and the switch unit 160 is used to control the start and stop of the fan. When the fan is working, the generated airflow can flow into the humidification device and mix with the water vapor generated in the water tank assembly 200, so that the airflow flowing out of the device body 100 can achieve the humidification effect.

[0089] Exemplarily, the switch unit 160 may be mounted on the fan bracket 120. The fan includes a motor 130, a wind wheel 140, and a mounting nut 150. The wind wheel 140 is connected to the output shaft of the motor 130 and is locked by the mounting nut 150.

[0090] In some embodiments, the float 220 can float with the water level in the box 210, so that the float 220 can abut or separate from the switch unit 160. In this way, the on-off state of the switch unit 160 can be controlled by the up and down floating of the float 220.

[0091] It is understandable that when the water level in the box 210 rises, the float 220 floats up, and the float 220 abuts and presses the switch unit 160, the switch unit 160 can be triggered, and the switch unit 160 switches from the open state to the closed state, so that the fan assembly starts to work. When the water level in the box 210 drops, the float 220 sinks, and the float 220 separates from the switch unit 160, or the float 220 abuts against the switch unit 160 but does not press the switch unit 160, the switch unit 160 switches from the closed state to the open state, and the fan assembly stops working. In this way, it can be ensured that the humidification device will only start when there is enough water in the box 210.

[0092] In addition, a touch panel or button located outside the shell 110 may be provided on the device body 100 of the humidifying device. The touch panel may have the function of displaying information such as the temperature, humidity, and power of the humidifying device, which is not specifically limited in the embodiment of the present application.

[0093] Exemplarily, the float 220 is located in the middle of the box 210, and a float bracket 230 is connected to the box 210, and the float 220 can be installed on the float bracket 230. The float bracket 230 can limit the float 220, ensuring that the float 220 is always opposite to the switch unit 160 when the float 220 floats up and down with the water level in the box 210. For example, the float bracket 230 can make the float 220 always stay on the same axis with the switch unit 160 in the vertical direction.

[0094] In the embodiment of the present application, an air outlet cover plate 170 may be connected to the housing 110, and the air outlet cover plate 170 is located at the air outlet side of the fan, and the humidified air flow may flow out from the air outlet cover plate 170. A clamping member may be provided on the air outlet cover plate 170, and the clamping member may be connected to the air outlet cover plate 170 by fasteners such as bolts. The air outlet cover plate 170 may be detachably connected to the housing 110 by the clamping member, so as to facilitate cleaning or maintenance of the components in the device body 100. Exemplarily, the clamping member may be a buckle.

[0095] It should be noted that an adjustment knob 180 may be provided on the air outlet cover 170 , and the adjustment knob 180 may adjust the opening and closing state and size of the air outlet of the air outlet cover 170 , or the adjustment knob 180 may adjust the air volume of the air outlet cover 170 .

[0096] The embodiment of the present application provides a humidifying device, including a device body, a water tank assembly and a filter assembly, wherein the device body is connected to the water tank assembly, the filter assembly is arranged in the water tank assembly, the filter assembly includes a bracket, an upper cover and a filter element, the upper cover is movably connected to the bracket, the first end of the filter element is connected to the bracket, and the second end of the filter element is connected to the upper cover; when the upper cover moves relative to the bracket, the filter element is folded or unfolded. When the filter element needs to be taken out of the water tank assembly, the filter element can be compressed by moving the upper cover to fold the filter element, thereby squeezing the water in the filter element out into the water tank assembly, and then the folded filter element is taken out of the water tank assembly to prevent the filter element from dripping when it is taken out, thereby improving the user experience.
