[0045] 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.

[0050] 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 be evaporated or atomized 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. The fan is controlled by a micro switch, which is set in the middle of the air inlet net below the fan blades. The float in the water tank is opposite to the micro switch, and the micro switch is pushed by the float to control the fan operation. However, due to the presence of the micro switch, the air inlet net and the fan blades cannot be disassembled and cleaned separately, which affects the user experience.

[0051] An embodiment of the present application provides a humidifying device, which adjusts the installation position of the switch unit and designs a driving structure of the switch unit. Without affecting the triggering and operation of the switch unit, the air inlet cover and the fan blades in the humidifying device can be disassembled and tilted, thereby improving the user experience.

[0052] To facilitate understanding, the application scenario of the humidification device provided in the embodiment of the present application is first described.

[0053] 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.

[0054] Figure 1 This is an exploded view of the humidification device provided in an embodiment of the present application. Figure 2 This is an exploded view of the air inlet assembly in the humidification device provided in the embodiment of the present application. Figure 3This is an exploded view of the device body in the humidification device provided in the embodiment of the present application, Figure 4 An exploded view of a water tank assembly in a humidification device provided in an embodiment of the present application.

[0055] like Figures 1 to 4 As shown, an embodiment of the present application provides a humidifying device, which includes a device body 100, an air inlet assembly 200 and a water tank assembly 300. The device body 100 is connected to the water tank assembly 300. The device body 100 includes a fan assembly 110 and a switch unit 120, and the switch unit 120 is connected to the fan assembly 110. The air inlet assembly 200 is connected to the air inlet side of the fan assembly 110.

[0056] The water tank assembly 300 stores water required for humidification, the fan assembly 110 is used to generate airflow, and the switch unit 120 is used to control the start and stop of the fan assembly 110. When the fan assembly 110 is working, the generated airflow can flow through the air inlet assembly 200 and mix with the water vapor generated in the water tank, so that the airflow flowing out of the device body 100 can achieve the effect of humidification.

[0057] In some embodiments, the air inlet assembly 200 includes an air inlet cover 210, a movable member 220, and a linkage member 230. The air inlet cover 210 has a movable hole 211, and the movable member 220 is inserted into the movable hole 211. The linkage member 230 is rotatably connected to the air inlet cover 210. The first end of the linkage member 230 abuts against the movable member 220, and the second end of the linkage member 230 is opposite to the switch unit 120. The movable member 220 is configured to move relative to the movable hole 211.

[0058] It is understandable that when the movable member 220 moves in the movable hole 211, the movable member 220 can drive the linkage member 230 to rotate relative to the air inlet cover 210. The linkage member 230 forms a lever structure on the air inlet cover 210, and the on and off state of the switch unit 120 is controlled by the rotation of the linkage member 230. When the linkage member 230 rotates to different positions, the linkage member 230 can drive the switch unit 120 to be turned on or off.

[0059] Figure 5 This is a cross-sectional view of a switch unit of a humidifying device provided in an embodiment of the present application when it is turned on. Figure 6 for Figure 5 Partial view of position A in the middle, Figure 7 This is a cross-sectional view of a humidifying device provided in an embodiment of the present application when the switch unit is disconnected. Figure 8 for Figure 7 Partial view of position B in the figure.

[0060] Exemplarily, the switch unit 120 in the embodiment of the present application is a normally closed switch, such as Figure 7 and Figure 8As shown, when the second end of the linkage member 230 abuts against the switch unit 120 and presses the switch unit 120, the switch unit 120 can be triggered, and the switch unit 120 switches from the closed state to the open state, so that the fan assembly 110 stops working. Figure 5 and Figure 6 As shown, when the second end of the linkage 230 is separated from the switch unit 120, or the second end of the linkage 230 is in contact with the switch unit 120 but does not press the switch unit 120, the switch unit 120 returns to the normally closed state, that is, switches from the open state to the closed state, and the fan assembly 110 can start working.

[0061] In addition, an external control switch may be provided on the device body 100 of the humidifying device, so that the user can control the on and off of the power supply of the humidifying device, thereby controlling the start and shut down of the humidifying device.

[0062] It should be noted that in the humidification device provided in the embodiment of the present application, the movable member 220 and the linkage member 230 are arranged on the air inlet cover 210 to cooperate with each other, thereby forming a lever structure, and the formed lever structure can trigger the switch unit 120. Therefore, the switch unit 120 does not need to be directly installed on the air inlet cover 210, and the air inlet cover 210 can be disassembled for cleaning, thereby improving the user experience. And when the air inlet cover 210 is disassembled, the linkage member 230 and the movable member 220 can be disassembled simultaneously with the air inlet cover 210.

[0063] First, the triggering method of the movable member 220 on the air inlet cover 210 will be described in detail below.

[0064] Please continue to refer to Figures 1 to 8 In a possible implementation, the water tank assembly 300 may include a box body 310 and a float 320, and the air inlet cover 210 is located between the box body 310 and the fan assembly 110. The float 320 is disposed in the box body 310, and the float 320 is configured to float with the water level in the box body 310, so that the float 320 abuts against or separates from the movable member 220. In this way, the movable member 220 can be moved by the up and down floating of the float 320, thereby controlling the abutting position of the linkage member 230 and the switch unit 120, and further controlling the on and off state of the switch unit 120.

[0065] It is understandable that the air inlet cover 210 is located above the water tank assembly 300, and the float 320 is opposite to the movable hole 211 on the air inlet cover 210. When the amount of water in the box body 310 is constantly used and is insufficient, the float 320 sinks, and the float 320 is at a lower position in the vertical direction. Therefore, the float 320 is separated from the movable member 220. During this process, the movable member 220 moves downward relative to the movable hole 211, and the first end of the linkage member 230 deflects as the movable member 220 moves downward, while the second end of the linkage member 230 moves upward, so that the second end of the linkage member 230 abuts against the switch unit 120 upward, and the switch unit 120 switches from the normally closed state to the open state, and then the fan assembly 110 stops working, prompting the user to add water.

[0066] When there is enough water stored in the box 310, the float 320 floats to a higher position, the float 320 contacts the movable member 220, and the float 320 pushes the movable member 220 to move upward relative to the movable hole 211. The first end of the linkage member 230 deflects as the movable member 220 moves upward, and the second end of the linkage member 230 moves downward, so that the second end of the linkage member 230 deflects away from the switch unit 120, and then the switch unit 120 returns from the disconnected state to the normally closed state, and the fan assembly 110 can work.

[0067] Exemplarily, the movable hole 211 can be set at the center of the air inlet cover 210, and an air inlet grille is set on the air inlet cover 210 around the movable hole 211. The float 320 is located in the middle of the box 310, and a float bracket 330 is connected to the box 310, and the float 320 can be inserted into the float bracket 330. The float bracket 330 can limit the float 320, ensuring that the float 320 is always opposite to the movable part 220 when the float 320 floats up and down with the water level in the box 310. For example, the float bracket 330 can make the float 320 always keep on the same axis with the movable part 220 in the vertical direction.

[0068] The specific structure of the movable member 220 is described in detail below.

[0069] In some embodiments, the movable member 220 may include a first abutting portion 221 and a second abutting portion 222. The first abutting portion 221 is located on the side of the movable hole 211 facing the fan assembly 110, and the first abutting portion 221 is at least partially inserted into the movable hole 211. The second abutting portion 222 is located on the side of the movable hole 211 facing the water tank assembly 300, and the second abutting portion 222 is at least partially inserted into the movable hole 211. The first abutting portion 221 and the second abutting portion 222 are connected.

[0070] It is understandable that the first abutting portion 221 is located on the upper side of the air inlet cover 210, and the second abutting portion 222 is located on the lower side of the air inlet cover 210, and the first abutting portion 221 and the second abutting portion 222 can be connected through the movable hole 211. When assembling the movable part 220, the first abutting portion 221 can be inserted from the upper side of the movable hole 211, and the second abutting portion 222 can be inserted from the lower side of the movable hole 211, so that the first abutting portion 221 and the second abutting portion 222 are butted, thereby improving the convenience of assembling the movable part 220 on the movable hole 211 and preventing the movable part 220 from falling out of the movable hole 211.

[0071] It should be noted that the projection of the first abutment portion 221 along the moving direction of the movable part 220 is at least partially located outside the projection range of the movable hole 211 along the moving direction of the movable part 220, so that the first abutment portion 221 can limit the movable part 220 to prevent the movable part 220 from falling into the water tank when the float 320 sinks.

[0072] Exemplarily, the movable hole 211 may be a circular hole, the diameter of the portion of the first abutting portion 221 inserted into the movable hole 211 is smaller than the diameter of the movable hole 211, and the diameter of the portion of the first abutting portion 221 located above and outside the movable hole 211 is larger than the diameter of the movable hole 211. The diameter of the portion of the second abutting portion 222 inserted into the movable hole 211 is smaller than the diameter of the movable hole 211, and the diameter of the portion of the second abutting portion 222 located below and outside the movable hole 211 is larger than the diameter of the movable hole 211.

[0073] In one embodiment, one of the first abutting portion 221 and the second abutting portion 222 may be provided with a snap-fitting hole 2211, and the other of the first abutting portion 221 and the second abutting portion 222 may be provided with a snap-fitting portion 2221, and the snap-fitting portion 2221 is snap-fitted with the snap-fitting hole 2211, thereby improving the convenience of assembling the first abutting portion 221 and the second abutting portion 222.

[0074] For example, the first abutting portion 221 may be provided with a plurality of snap-fitting holes 2211, which are spaced apart in the circumferential direction of the first abutting portion 221, and the second abutting portion 222 may be provided with a plurality of snap-fitting portions 2221, which are spaced apart in the circumferential direction of the second abutting portion 222. The plurality of snap-fitting holes 2211 and the plurality of snap-fitting portions 2221 are arranged in a one-to-one correspondence.

[0075] In another embodiment, the first abutting portion 221 and the second abutting portion 222 may be connected by fasteners such as bolts. The embodiment of the present application does not limit the specific connection method of the first abutting portion 221 and the second abutting portion 222.

[0076] Fig. 9This is an exploded view of the air inlet assembly and the float in the humidification device provided in an embodiment of the present application.

[0077] The following is a detailed description of the installation method of the linkage member 230 on the air inlet cover 210 and the specific structure of the linkage member 230.

[0078] Please refer to Figures 1 to 9 In the embodiment of the present application, the air inlet cover 210 may be provided with a slot 212, and the linkage member 230 has a shaft portion 231, and the shaft portion 231 is located in the slot 212, thereby preventing the linkage member 230 from being displaced or shaken during the rotation process.

[0079] It is understandable that the shaft portion 231 is located between the first end and the second end of the linkage member 230, so that the linkage member 230 can form a lever structure on the air inlet cover 210, and when one end of the linkage member 230 deflects upward, the other end of the linkage member 230 can deflect downward.

[0080] In some embodiments, the linkage member 230 may include a rotating body 232, a first bending section 233, and a second bending section 234. The first bending section 233 is connected to one end of the rotating body 232 facing the movable member 220, and the first bending section 233 is deflected toward the movable member 220 relative to the rotating body 232. The second bending section 234 is connected to one end of the rotating body 232 away from the movable member 220, and the second bending section 234 is deflected toward the switch unit 120 relative to the rotating body 232.

[0081] It is understandable that the movable member 220 is located below the first end of the linkage member 230, and the first bending section 233 is provided to avoid the structure of the fan assembly 110, thereby avoiding interference during the rotation of the linkage member 230. The switch unit 120 is located above the second end of the linkage member 230, and the second bending section 234 is provided to avoid the structure of the fan assembly 110, thereby avoiding interference during the rotation of the linkage member 230.

[0082] In the embodiment of the present application, the fan assembly 110 may include a fan bracket 111. The switch unit 120 is connected to the side of the fan bracket 111. The fan assembly 110 also includes a motor 112, a wind wheel 113, and a fixing nut 114. The motor 112 is mounted on the fan bracket 111 through fasteners such as bolts, and the wind wheel 113 is connected to the output shaft of the motor 112 through the fixing nut 114. The motor 112 can drive the wind wheel 113 to rotate to generate airflow.

[0083] The second bending section 234 at least partially extends to the side of the fan bracket 111, so that the switch unit 120 can be installed separately and away from the air inlet cover 210. When the air inlet cover 210 is removed, interference between the switch unit 120 and the air inlet cover 210 can be avoided.

[0084] Exemplarily, the second bending section 234 has an abutment protrusion 2341 at one end facing the switch unit 120. The switch unit 120 may include a switch body 121 and a switch spring piece 122 connected to the switch body 121. The abutment protrusion 2341 is opposite to the switch spring piece 122, thereby improving the reliability of the abutment cooperation between the linkage member 230 and the switch unit 120.

[0085] Exemplarily, an abutment groove may be provided at the top of the abutment protrusion 2341, and the cross-section of the abutment groove may be a "U"-shaped structure. When the abutment protrusion 2341 abuts against the switch spring piece 122, the switch spring piece 122 may abut against the abutment groove to avoid misalignment between the switch spring piece 122 and the linkage member 230.

[0086] It should be noted that the device body 100 may further include a housing 130, the fan bracket 111 may be installed in the housing 130 by fasteners such as bolts, and an air outlet cover 140 may be connected to the housing 130, the air outlet cover 140 is located on the air outlet side of the fan assembly 110, and the humidified air flow may flow out from the air outlet cover 140. The air outlet cover 140 may be provided with an adjustment knob 141, and the adjustment knob 141 may adjust the opening and closing state and size of the air outlet of the air outlet cover 140, or the adjustment knob 141 may adjust the air volume of the air outlet cover 140.

[0087] In some embodiments, the air inlet assembly 200 may further include a cover plate 240, which is connected to the side of the air inlet cover 210 facing the fan assembly 110. The cover plate 240 has an extension portion 241, which is arranged on the side of the linkage member 230 away from the air inlet cover 210. The cover plate 240 can limit the linkage member 230, limit the rotation stroke of the linkage member 230, and prevent the linkage member 230 from falling off from the air inlet cover 210.

[0088] It is understandable that the main structure of the cover plate 240 may be opposite to the movable hole 211, and the extension portion 241 may extend from the main structure of the cover plate 240 to the edge of the air inlet cover 210. The extension direction of the extension portion 241 is the same as or similar to the extension direction of the rotating body 232 of the linkage member 230, so that the extension portion 241 can be blocked above the rotating body 232 of the linkage member 230.

[0089] Exemplarily, the rotating body 232 , the first bending section 233 , and the second bending section 234 of the linkage member 230 may be an integrally formed part.

[0090] For example, the main structure of the extension 241 and the cover plate 240 may be an integrally formed part. The main structure of the cover plate 240 may be connected to the air inlet cover 210 by a buckle, or the main structure of the cover plate 240 may be connected to the air inlet cover 210 by fasteners such as bolts, which is not specifically limited in the embodiments of the present application.

[0091] In some embodiments, the air inlet assembly 200 may further include an elastic member 250, which is connected to a side of the cover plate 240 facing the linkage member 230, and the elastic member 250 abuts against a first end of the linkage member 230. When the float 320 sinks, the elastic member 250 may push the linkage member 230 to automatically reset, so that the linkage member 230 abuts against the switch unit 120.

[0092] It can be understood that the elastic member 250 abuts against the top of the first bending section 233 of the linkage member 230, and the elastic member 250 applies an elastic force to the linkage member 230 toward the movable member 220. When the float 320 sinks and separates from the movable member 220, the elastic force of the elastic member 250 can push the first end of the linkage member 230 to deflect downward, and then the second end of the linkage member 230 to deflect upward.

[0093] For example, the elastic member 250 may be a spring. A fixing buckle 242 may be provided on the side of the cover plate 240 facing the air inlet cover 210, and the elastic member 250 may be sleeved on the fixing buckle 242. The fixing buckle 242 may position and fix the elastic member 250, and prevent the elastic member 250 from falling off the cover plate 240. In addition, the fixing buckle 242 may guide the elastic member 250 when the elastic member 250 is compressed and rebounded.

[0094] It should be noted that the water tank assembly 300 in the embodiment of the present application may also include a filter element 340 , which is placed in the box body 310 . The filter element 340 may be an annular cylindrical structure, and the filter element 340 may absorb impurities in the water of the box body 310 .

[0095] The humidifying device provided in the present application includes a device body, an air inlet assembly and a water tank assembly; the device body is connected to the water tank assembly; the device body includes a fan assembly and a switch unit, and the switch unit is connected to the fan assembly; the air inlet assembly is connected to the air inlet side of the fan assembly, and the air inlet assembly includes an air inlet cover, a movable part and a linkage part; the air inlet cover has a movable hole, and the movable part is inserted through the movable hole; the linkage part is rotatably connected to the air inlet cover; the first end of the linkage part abuts against the movable part, and the second end of the linkage part is opposite to the switch unit; the movable part is configured to move relative to the movable hole so that the second end of the linkage part drives the switch unit to be connected or disconnected, so that the switch unit does not need to be directly installed on the air inlet cover, and the air inlet cover can be disassembled for cleaning, thereby improving the user experience.
