Description

Technical Field

[0001] The present application relates to the technical field of humidification treatment, and in particular to a water tank device and a humidifier. Background Art

[0002] After staying in an air-conditioned room for a long time, users will easily feel the dryness of the environment. In order to reduce the impact of the dry environment, some users will use a humidifier to increase the humidity of the indoor air.

[0003] In order to release moisture into the indoor air, the humidifier needs to continuously consume internal water storage during operation. To ensure that the humidifier can work continuously, some humidifiers require users to refill water regularly. To facilitate users to collect water, some humidifiers are equipped with a removable water tank. When refilling water, users can only pull out the water tank, then go to the faucet and let the water flow in from the upper opening of the water tank. However, after the water tank is filled with water, the overall weight is relatively large, which brings great physical exertion to the user and causes a decline in the user experience.

[0054] The technical solution provided by the embodiments of the present application is described below in conjunction with the accompanying drawings.

[0055] Combination Figures 1 to 24 As shown, the present application provides a humidifier 100 .

[0056] In some embodiments, the humidifier 100 is used to humidify the indoor environment to increase the indoor humidity. In another embodiment, the humidifier 100 can also be used to humidify outdoors to increase the humidity of the space near the humidifier 100.

[0057] In some embodiments, in combination Figure 1 and Figure 5 As shown, the humidifier 100 includes a body 30 and a water tank device 90. The body 30 is used to carry and limit the water tank device 90. The water tank device 90 is used to store liquid, and the liquid is used to increase the humidity of the gas. Specifically, the body 30 is provided with a storage cavity 911. Further, the body 30 can also be other components used to support, accommodate or cover the humidifier 100.

[0058] Combination Figure 6 and Figure 7 As shown, the present application also provides a water tank device 90 .

[0059] In some embodiments, in combination Figure 6 and Figure 7 As shown, the water tank device 90 includes: a water tank body 91 and a drainage member 92. The water tank body 91 is provided with a storage chamber 911. The water tank body 91 forms an inlet 912 at the upper part of the storage chamber 911, and the inlet 912 is used to inject liquid. The drainage member 92 has an input interface 921 and an injection port 922. The drainage member 92 is also provided with a flow channel, and the flow channel is respectively connected to the input interface 921 and the injection port 922. The input interface 921 is used to connect to the liquid replenishment pump 20 of the humidifier 100. The flow channel of the drainage member 92 is used to guide the liquid in the translational carrier 001 to flow from bottom to top through the input interface 921 and spray into the storage chamber 911 through the injection port 922.

[0060] Specifically, the water tank device 90 is used to be removably loaded into the body 30 of the humidifier 100. When the user manually replenishes the water tank device 90 with liquid used for humidification, the user can remove the water tank device 90 from the body 30 and then place the filling port 912 under the faucet to allow liquid to flow in from the filling port 912. When the user needs to replenish the liquid used in the humidifier 100 through the translational carrier 001, the input interface 921 of the drainage member 92 is connected to the port of the liquid replenishing pump 20 of the humidifier 100, and the liquid replenishing pump 20 can be connected to the translational carrier 001. The liquid loaded by the translational carrier 001 can flow from bottom to top through the drainage member 92 and be sprayed into the storage chamber 911 through the injection port 922, so that the water tank device 90 can automatically input the liquid carried by the translational carrier 001 when it is carried on the fuselage 30, avoiding the user from taking out the water tank device 90 and manually filling it with liquid to replenish the liquid inside the humidifier 100, thereby saving a lot of physical strength and helping to improve user experience.

[0061] In some embodiments, in combination Figures 3 to 5 As shown, the humidifier 100 further includes a liquid replenishing pump 20 disposed on the body 30, the first discharge port 21 of the liquid replenishing pump 20 is used to be connected to the input interface 921, and the first suction port 22 of the liquid replenishing pump 20 is used to be connected to the translational carrier 001. Specifically, when the liquid replenishing pump 20 is in operation, the first suction port 22 is in a negative pressure state, so that the liquid loaded by the translational carrier 001 can be sucked in, and then the liquid is transported from bottom to top to the storage chamber 911 through the first discharge port 21. Therefore, the storage chamber 911 can be replenished with liquid without the water tank device 90 leaving the body 30, and the need to carry the water storage container is avoided.

[0062] In some embodiments, in combination Figure 1 and Figure 2 As shown, a docking surface 33 is provided on the outside of the fuselage 30 , and the docking surface 33 is at least partially used to abut against the translation vehicle 001 .

[0063] In some embodiments, in combination Figures 1 to 3 As shown, the humidifier 100 includes a water replenishment interface 331, which can be connected to the storage chamber 911. When the water replenishment interface 331 is docked with the water outlet 002 of the translational carrier 001, the liquid of the translational carrier 001 is guided to be transported to the water tank device 90 through the water replenishment interface 331. More specifically, the water replenishment interface 331 is used to dock with the water outlet 002 of the translational carrier 001 to guide the liquid to the storage chamber 911.

[0064] In one embodiment, in combination Figure 2As shown, the water replenishment interface 331 is provided on the docking surface 33. In some embodiments, the water replenishment interface 331 is an accordion-type interface device, and in other embodiments, the water replenishment interface 331 may also be an interface device of other shapes, and the shape of the water replenishment interface 331 is not specifically limited. In some embodiments, the water replenishment interface 331 is close to the bottom of the fuselage 30, and in other embodiments, the water replenishment interface 331 may also be at other positions of the fuselage 30.

[0065] In some embodiments, in combination Figure 1 and Figure 2 As shown, the humidifier 100 also includes a detection electrode 334 connected to the docking surface 33 and a control module electrically connected to the detection electrode 334. The rehydration pump 20 is used as a fluid driving member for generating a fluid suction force on the liquid. When the detection electrode 334 is electrically connected to the translational carrier 001, the control module triggers the rehydration pump 20 to operate and extracts the liquid of the translational carrier 001 to the storage chamber 911. When it is detected that the storage chamber 911 of the humidifier 100 is full of liquid or the internal liquid storage container of the translational carrier 001 is emptied of liquid, the control module controls the rehydration pump 20 to stop working, and the translational carrier 001 automatically leaves the humidifier 100 under the control of the internal controller, returns to the preset position or refills the internal liquid storage container with water again, and can be repeatedly moved to the humidifier 100 to automatically refill it with water as needed.

[0066] Specifically, the detection electrode pieces 334 are arranged in pairs. The outer side of the translational carrier 001 is provided with conductive electrode pieces 005 in pairs, and the conductive electrode pieces 005 are used to be attached to the detection electrode pieces 334 one by one. In some embodiments, a conductor or a power supply is connected between the two detection electrode pieces 334, and a conductor or a power supply is additionally connected between the two conductive electrode pieces 005. When the control module recognizes that there is a voltage or electric quantity between the detection electrode pieces 334, it can be determined that the detection electrode piece 334 is electrically connected with the translational carrier 001.

[0067] In some embodiments, the humidifier 100 does not need to be additionally provided with a charging connector, and the detection electrode 334 itself can be used as a charging connector. When the detection electrode 334 is docked to the translational carrier 001, the detection electrode 334 is used to conduct electrical energy to the translational carrier 001.

[0068] Furthermore, combined with Figure 5As shown, the first suction port 22 of the rehydration pump 20 is connected to the water replenishment interface 331, and the first discharge port 21 of the rehydration pump 20 is connected to the storage chamber 911. When the rehydration pump 20 is running, the water replenishment interface 331 is in a negative pressure state, so that the liquid loaded by the translational carrier 001 is sucked into the water replenishment interface 331, and then the liquid is transported from bottom to top to the storage chamber 911 through the first discharge port 21. In some embodiments, a pipeline is connected between the first suction port 22 of the rehydration pump 20 and the water replenishment interface 331. Another pipeline is connected between the first discharge port 21 of the rehydration pump 20 and the storage chamber 911. In another embodiment, the first suction port 22 of the rehydration pump 20 and the water replenishment interface 331 can also be directly connected. Or the first discharge port 21 of the rehydration pump 20 is directly connected to the interface of the storage chamber 911. In some embodiments, the rehydration pump 20 is provided with an anti-diversion structure at the first suction port 22 to limit the liquid from the inside of the rehydration pump 20 to flow back to the outside of the first suction port 22. In some other embodiments, the infusion pump 20 is provided with an anti-flow structure at the first outlet 21 to limit the backflow of liquid from the outside of the first outlet 21 into the infusion pump 20 .

[0069] In some embodiments, in combination Figure 5 As shown, the humidifier 100 also includes an adapter 25 and a fluid infusion conduit 23. The adapter 25 includes a first pipe section 26 and a second pipe section 27, and the first pipe section 26 and the second pipe section 27 are connected and arranged at an angle. The first pipe section 26 is connected to the water infusion interface 331. The second pipe section 27 is connected to the first suction port 22 of the fluid infusion pump 20 through the fluid infusion conduit 23. Specifically, since the first pipe section 26 and the second pipe section 27 have a fixed relative angle, the internal circulation space can be maintained stable. By adjusting the flow direction of the liquid using the adapter 25, the fluid infusion conduit 23 can be prevented from being blocked due to excessive bending in the limited internal space of the fuselage 30. It can be understood that the fluid infusion conduit 23 is a pipe connected between the first suction port 22 of the fluid infusion pump 20 and the water infusion interface 331.

[0070] In some embodiments, in combination Figure 4 and Figure 5As shown, the humidifier 100 also includes a fixed joint 24, which is connected to the first discharge port 21 of the liquid replenishment pump 20. A first support surface 32 is provided in the fuselage 30. The fixed joint 24 is arranged on the first support surface 32 and is sealed and docked with the input interface 921 of the drainage member 92. Specifically, by providing a fixed joint 24 connected to the fuselage 30, when the water tank device 90 abuts against the first support surface 32 on the fuselage 30, the fixed joint 24 can be used to dock to the input interface 921 of the drainage member 92, so as to achieve communication between the drainage member 92 and the water replenishment interface 331. When the fixed joint 24 is sealed and docked with the input interface 921 of the drainage member 92, liquid can be prevented from leaking from the periphery of the fixed joint 24. In one embodiment, the inner periphery of the input interface 921 is sealed and abutted against the periphery of the fixed joint 24.

[0071] In some embodiments, in combination Figure 4 As shown, the first support surface 32 is connected with a convex edge portion 321, which is arranged to be raised relative to the first support surface 32, and the convex edge portion 321 surrounds at least a portion of the periphery of the fixed joint 24. Specifically, when a small amount of liquid accidentally flows down from the fixed joint 24 to the first support surface 32, since the convex edge portion 321 is raised relative to the first support surface 32, the convex edge portion 321 can limit the liquid from flowing in any direction around, thereby preventing the liquid from affecting the body 30 or other devices.

[0072] In some embodiments, in combination Figure 1 and Figure 2 As shown, the humidifier 100 further includes a positioning structure 335, which is disposed on the docking surface 33, and is used to be positioned and matched with the translational carrier 001. When the positioning structure 335 is positioned and matched with the translational carrier 001, the water replenishment interface 331 is docked with the water outlet 002 of the translational carrier 001 to transport the liquid of the translational carrier 001 to the storage chamber 911.

[0073] Specifically, the humidifier 100 increases the humidity by distributing the liquid in the storage chamber 911 into the ambient air. The translational carrier 001 has a container capable of carrying liquid, and the translational carrier 001 can slide on the ground through components such as wheels. Next, the water outlet 002 of the translational carrier 001 is docked to the water replenishment interface 331 on the outside of the fuselage 30. Thereafter, when the fluid driving member in the humidifier 100 or the translational carrier 001 generates fluid suction, the liquid in the translational carrier 001 is transferred to the storage chamber 911 through the water outlet 002 and the water replenishment interface 331. Since the water outlet 002 and the water replenishment interface 331 are at the same height, as long as the translational carrier 001 is automatically translated, the water outlet 002 and the water replenishment interface 331 can be automatically docked, thereby avoiding the need to lift the water receiving container and eliminating the need for multiple manual water additions, which is beneficial to improving the user experience of the humidifier 100.

[0074] In some embodiments, in combination Figure 1 and Figure 2 As shown, the docking surface 33 is provided with a plurality of positioning structures 335, wherein two positioning structures 335 are arranged on two opposite sides of the water replenishment interface 331. Since the positioning structures 335 on both sides of the water replenishment interface 331 are docked to the translational carrier 001, both sides of the water replenishment interface 331 are subject to the position limitation of the positioning structures 335, thereby enabling the water replenishment interface 331 to be reliably docked to the water outlet 002 of the translational carrier 001.

[0075] Furthermore, in combination with certain detection and control mechanisms, when the translational carrier 001 is filled with water or the humidifier 100 needs to be refilled with water, the controller of the translational carrier 001 can control the internal driving module to automatically move to the vicinity of the humidifier 100 and automatically refill the humidifier 100 with liquid.

[0076] In some embodiments, the shape of the docking surface 33 corresponds to the shape of the outer wall surface 003 of the translational carrier 001 near the water outlet 002. Specifically, after the water replenishment interface 331 is docked with the water outlet 002, at least a portion of the docking surface 33 is attached to the outer wall surface 003 near the water outlet 002. Since the shape of the docking surface 33 corresponds to the shape of the outer wall surface 003 near the water outlet 002, the position of the translational carrier 001 can be kept stable relative to the body 30 of the humidifier 100 by the attachment of at least a portion of the docking surface 33 to the outer wall surface 003 near the water outlet 002.

[0077] In some embodiments, the docking surface 33 may be in a concave shape to fit with part of the outer peripheral surface of the translational vehicle 001, so that the translational vehicle 001 maintains a predetermined position relative to the fuselage 30. In some embodiments, the docking surface 33 is in a concave arc shape, and in other embodiments, the docking surface 33 may also be in other shapes, such as a groove shape. Specifically, when the water replenishment interface 331 is located near the middle position of the docking surface 33, the parts on both sides of the docking surface 33 can guide the translational vehicle 001.

[0078] In some embodiments, the positioning structure 335 is a positioning groove for accommodating a limiting protrusion of the translational transport device 001. Specifically, the limiting protrusion is arranged near the water outlet 002. When the size of the positioning groove is just enough to accommodate the limiting protrusion, it can play a positioning role between the fuselage 30 and the translational transport device 001.

[0079] In some embodiments, in combination Figure 1 and Figure 2 As shown, the positioning structure 335 is a positioning block 336, which is used to be inserted into the limiting groove 004 of the translational carrier 001. Specifically, the limiting groove 004 is arranged near the water outlet 002, and the size of the limiting groove 004 is just enough to accommodate the positioning block 336. Further, in the case where the positioning structure 335 is a positioning block 336, the diameter of the end of the positioning block 336 away from the fuselage 30 is smaller than the diameter of the end close to the fuselage 30. The end of the positioning block 336 away from the fuselage 30 is the outer end, and the end of the positioning block 336 close to the fuselage 30 is the inner end. When the outer end of the positioning block 336 is about to enter the opening of the limiting groove 004, since the diameter of the outer end of the positioning block 336 is smaller than that of the inner end, even if the center of the outer end of the positioning block 336 deviates greatly from the center of the opening of the limiting groove 004, as long as the outer end edge of the positioning block 336 is within the opening edge of the limiting groove 004, it can be ensured that the outer end of the positioning block 336 can smoothly enter the opening of the limiting groove 004.

[0080] In some embodiments, among the plurality of positioning structures 335 , at least one positioning structure 335 is a positioning groove, and another at least one positioning structure 335 is a positioning block 336 .

[0081] In some embodiments, in combination Figure 1 and Figure 2As shown, the humidifier 100 further includes a positioning module 337 disposed on the docking surface 33. The positioning module 337 is used to send a positioning signal that can guide the translation vehicle 001 to approach the docking surface 33. Specifically, at least one angle of the translation vehicle 001 can receive the positioning signal. When the translation vehicle 001 receives the positioning signal, the translation vehicle 001 determines the relative direction between itself and the humidifier 100 according to the source direction of the positioning signal. Then, the translation vehicle 001 automatically moves closer to the humidifier 100 along the relative direction, thereby facilitating the automatic positioning guidance between the translation vehicle 001 and the humidifier 100.

[0082] In some embodiments, the positioning signal is an infrared signal. The positioning module 337 transmits the positioning signal from the transmitting point to multiple directions, so that the translation vehicle 001 can receive the positioning signal at different positions. In other embodiments, the translation vehicle 001 can also find the position of the humidifier 100 according to a pre-stored map or other methods.

[0083] In some embodiments, the humidifier 100 is connected to the mains, and the humidifier 100 also includes a charging connector disposed on the docking surface 33. The charging connector is used to dock to the translation vehicle 001 and conduct electrical energy. Specifically, when the humidifier 100 is electrically connected to the power supply, the humidifier 100 can output electrical energy to the translation vehicle 001 through the charging connector. More specifically, an energy storage device is disposed in the translation vehicle 001, and the energy storage device replenishes electrical energy at intervals through the charging connector, so that the translation vehicle 001 can operate continuously. In one embodiment, the energy storage device is a lithium battery. In some embodiments, when the translation vehicle 001 outputs liquid to the storage chamber 911, the charging connector outputs electrical energy to the energy storage device synchronously or separately.

[0084] In some other embodiments, the humidifier 100 is not connected to the mains, and the translational carrier 001 has a supply position corresponding to the use environment. After the translational carrier 001 moves to the supply position, the supply position transmits electric energy to the translational carrier 001 by wired or wireless means, so that the power of the energy storage device is increased. In one embodiment, when the translational carrier 001 is a cleaning robot, the supply position is set on a cleaning base station connected to the mains, and the cleaning robot can automatically transport the collected garbage to the integrated bucket or dust bag of the base station, and can also obtain electric energy from the supply position of the cleaning base station. When the translational carrier 001 transfers the electric energy in the energy storage device to the humidifier 100 via the charging connector, the humidifier 100 can obtain electric energy replenishment and continue to work. In some embodiments, when the translational carrier 001 outputs liquid to the storage chamber 911, the charging connector synchronously receives electric energy from the energy storage device.

[0085] In some embodiments, in combination Figure 8 and Fig.11 As shown, the humidifier 100 further includes an outer cover 34 detachably connected to the docking surface 33. The outer cover 34 is used to cover the docking surface 33. Specifically, by providing a detachable outer cover 34, when the humidifier 100 does not need to replenish liquid through the water replenishment interface 331, the outer cover 34 can cover the docking surface 33 and the water replenishment interface 331, thereby providing protection for the water replenishment interface 331 and the positioning structure 335, which is more beautiful.

[0086] In some embodiments, in combination Fig.11 As shown, the outer cover 34 is provided with a hand-grip structure 342, which is provided at the bottom of the outer cover 34 and is used to remove the outer cover 34 from the docking surface 33. In one embodiment, the hand-grip structure 342 is a buckleable groove, and a wall surface of the buckleable groove faces the docking surface 33. The user's finger applies a pressure against the docking surface 33 to the wall surface of the buckleable groove, so that the outer cover 34 can be separated from the docking surface 33. Furthermore, the opening direction of the buckleable groove is set downward, and the outer surface of the outer cover 34 forms a flat plate surface, which is conducive to improving the aesthetics of the outer cover 34.

[0087] In another embodiment, the hand-clasp structure 342 is protruded relative to the outer surface of the outer cover 34 , and the user can apply a pulling force to the outer cover 34 in the direction away from the docking surface 33 by clamping the hand-clasp structure 342 with his hands, thereby detaching the outer cover 34 from the docking surface 33 .

[0088] In some embodiments, in combination Fig. 9 and Fig.11 As shown, a plurality of elastic support parts 341 are connected to one side of the outer cover 34 facing the docking surface 33. The elastic support parts 341 are used to abut the docking surface 33. Specifically, along the relative direction between the outer cover 34 and the docking surface 33, the extension length of the elastic support parts 341 corresponds to the relative distance between the outer cover 34 and the docking surface 33. When the outer surface of the outer cover 34 is impacted, the elastic support parts 341 abut the docking surface 33, thereby preventing the outer cover 34 from breaking due to excessive deformation. In some embodiments, the extension length of the elastic support parts 341 is equal to or slightly less than the relative distance between the outer cover 34 and the docking surface 33.

[0089] In some embodiments, the docking surface 33 is provided with one of the first card block 343 or the first card slot 332, and the inner wall of the outer cover 34 is provided with the other of the first card block 343 or the first card slot 332. The first card block 343 and the first card slot 332 cooperate with each other, thereby realizing a detachable connection between the outer cover 34 and the docking surface 33.

[0090] In one embodiment, in combination Fig. 9 and Fig.11As shown, the inner wall of the outer cover 34 is provided with a first clamping block 343, and the docking surface 33 is provided with a first clamping groove 332. The first clamping block 343 is clamped in the first clamping groove 332, so that the outer cover 34 can be detachably connected to the docking surface 33, and the outer surface of the outer cover 34 can remain flat.

[0091] In another embodiment, the docking surface 33 is provided with a first clamping block 343 , and the inner wall of the outer cover 34 is provided with a first clamping groove 332 . The first clamping block 343 is clamped in the first clamping groove 332 , thereby realizing a detachable connection between the outer cover 34 and the docking surface 33 .

[0092] In some embodiments, a second card block 344 or a second card slot 333 is provided at the fuselage 30 near the docking surface 33, and the other of the second card block 344 or the second card slot 333 is provided at the top of the outer cover 34. The second card block 344 and the second card slot 333 cooperate with each other to align the edge of the top of the outer cover 34 with the surface of the fuselage 30 near the docking surface 33.

[0093] In one embodiment, in combination Fig. 9 and Fig.11 As shown, the fuselage 30 is provided with a second slot 333 near the docking surface 33, and the top of the outer cover 34 is provided with a second block 344, which is used to be inserted into the second slot 333, so as to ensure that the shape of the edge of the top of the outer cover 34 corresponds to the shape of the edge of the fuselage 30 near the docking surface 33, so that the outer surface of the outer cover 34 and the fuselage 30 near the docking surface 33 are smoothly transitioned, and the outer cover 34 is prevented from being unable to align with the outer surface of the fuselage 30 due to processing errors. Further, a plurality of second blocks 344 are distributed along the edge of the top of the outer cover 34, and a plurality of second slots 333 are distributed along the edge of the fuselage 30 near the docking surface 33.

[0094] In one embodiment, a second card slot 333 is provided at the top of the outer cover 34, and a second card block 344 is provided at the fuselage 30 near the docking surface 33. The second card block 344 is used to be inserted into the second card slot 333, thereby ensuring that the shape of the edge of the top of the outer cover 34 corresponds to the shape of the edge of the fuselage 30 near the docking surface 33.

[0095] In some embodiments, the second card block 344 or the second card slot 333 and the buckle structure 342 for detachable connection can be respectively set at the top and bottom ends of the outer cover 34, or can be respectively set at the opposite left and right ends according to specific circumstances to facilitate user operation.

[0096] In some embodiments, in combination Figure 12 to Figure 14As shown, the humidifier 100 includes: a body 30, a tank body 40, a filter assembly 50, a drainage assembly 60 and a liquid supply pump 43. The tank body 40 is accommodated in the body 30, and the tank body 40 is provided with a liquid tank 41, and the liquid tank 41 is used to hold liquid. The filter assembly 50 is at least partially located above the liquid tank 41, and the filter assembly 50 includes a filter bracket 51 and a filter body 52 connected to the filter bracket 51. The drainage assembly 60 is used to disperse the liquid in the liquid tank 41 to different positions of the filter body 52. ​​The liquid supply pump 43 is connected to the drainage assembly 60 and is used to pump the liquid in the liquid tank 41 from bottom to top to the filter body 52 through the drainage assembly 60 in the working state, and is used to prevent the filter body 52 from contacting the liquid contained in the liquid tank 41 in the non-working state.

[0097] Specifically, in the working state, the liquid flows along the liquid tank 41 to the periphery of the liquid supply pump 43, and the impeller in the liquid supply pump 43 rotates. After the liquid around the liquid supply pump 43 enters the liquid supply pump 43, the liquid flows into the drainage component 60 under the pressure of the impeller. The liquid rises along the drainage component 60 to a height higher than the upper edge of the filter body 52, and then the liquid drips from a plurality of mutually dispersed positions to the filter body 52, so that the filter body 52 can be evenly moistened. In the non-working state, since the filter body 52 is isolated from the storage space for holding liquid in the liquid tank 41, the filter body 52 does not contact the liquid contained in the liquid tank 41, which can avoid the filter body 52 from being easily generated with bacteria due to the liquid always adhering to the filter body 52, and prevent the humidifier 100 with bacteria on the filter for long-term use, thereby reducing the harm to the human body.

[0098] In some embodiments, the water replenishment interface 331 is used to dock with the water outlet 002 of the translational carrier 001 to guide the liquid of the translational carrier 001 to be input into the liquid tank 41. Specifically, the water outlet 002 is provided on the outer surface of the translational carrier 001. When the translational carrier 001 is in a predetermined position relative to the fuselage 30, the water replenishment interface 331 can be accurately docked with the water outlet 002 of the translational carrier 001. After the liquid in the translational carrier 001 flows into the liquid tank 41 through the water outlet 002 and the water replenishment interface 331, the liquid in the liquid tank 41 is replenished. Therefore, according to a certain detection and control mechanism, when the liquid in the liquid tank 41 is consumed more, the humidifier 100 needs to replenish liquid or the translational carrier 001 is filled with water, the translational carrier 001 can automatically run to the side of the humidifier 100 by the internal driving module, and replenish liquid to the liquid tank 41, so that the humidifier 100 can work continuously.

[0099] In some embodiments, in combination Fig.12 and Fig.13As shown, the body 30 is provided with a side opening 35, and the side opening 35 is used for the tank body 40 to enter the internal space of the body 30. Further, the tank body 40 can be installed inside the body 30 together with the filter assembly 50 and the drainage assembly 60 through the side opening 35. Further, the humidifier 100 also includes a side shell detachably connected to the body 30, and the side shell is used to cover the side opening 35.

[0100] In some embodiments, in combination Fig.13 and Fig. 22 As shown, the filter bracket 51 is isolated from the portion of the liquid tank 41 for containing liquid, thereby preventing the liquid from always adhering to the surface of the filter bracket 51 and preventing liquid from remaining on the surface of the filter bracket 51, so that the surface of the filter bracket 51 can remain relatively dry after the humidifier 100 is used for a long time.

[0101] In one embodiment, the lower end of the filter support 51 is higher than the highest liquid level allowed to be contained in the liquid tank 41. Specifically, since the lower end of the filter support 51 is higher than the highest liquid level allowed to be contained in the liquid, even if the liquid flows in the horizontal direction due to leakage, it will not contact the filter support 51, thereby reliably ensuring that the filter support 51 is isolated from the liquid in the liquid tank 41.

[0102] In some embodiments, the filter body 52 is isolated from the portion of the liquid tank 41 for containing liquid. Specifically, by isolating the filter body 52 from the portion of the liquid tank 41 for containing liquid, it is possible to prevent the liquid from always adhering to the filter body 52, which may cause bacteria to easily grow on the filter body 52, thereby preventing the humidifier 100 from being used for a long time with a filter containing bacteria, and reducing the harm to the human body.

[0103] In one embodiment, the lower end of the filter body 52 is higher than the highest liquid level allowed to be contained in the liquid tank 41. Specifically, since the lower end of the filter body 52 is higher than the highest liquid level allowed to be contained in the liquid, even if the liquid flows in the horizontal direction due to leakage, it will not contact the filter body 52, thereby reliably ensuring that the filter body 52 is isolated from the liquid in the liquid tank 41.

[0104] In some embodiments, in combination Fig.14 and Fig. 22 As shown, a second support surface 42 adjacent to the liquid tank 41 is provided in the tank body 40. The height of the second support surface 42 is greater than or equal to the upper edge of the liquid tank 41. Specifically, under normal use, the maximum height of the liquid level is lower than or equal to the upper edge of the liquid tank 41. In one embodiment, the length of the second support surface 42 is greater than the length of the opening of the liquid tank 41 to improve the support stability of the second support surface 42.

[0105] In some embodiments, the second support surface 42 is used to support the lower end of the filter support 51, so as to ensure that the lower end of the filter support 51 is higher than the highest liquid level allowed to accommodate liquid in the liquid tank 41, and avoid the filter support 51 from contacting the liquid in the liquid tank 41. In some embodiments, the second support surface 42 is used to support the lower end of the filter body 52, so as to ensure that the lower end of the filter body 52 is higher than the highest liquid level allowed to accommodate liquid in the liquid tank 41, and avoid the filter body 52 from contacting the liquid in the liquid tank 41.

[0106] In some embodiments, in combination Fig.14 and Fig.17 As shown, the filter body 52 is sleeved on the outer periphery of the filter bracket 51. The filter body 52 has a plurality of gaps through which air can pass. In some embodiments, the body 30 is frame-shaped to facilitate the disassembly and assembly of the filter assembly 50 or the tank body 40.

[0107] In some embodiments, in combination Fig.14 and Fig. 22 As shown, the liquid supply pump 43 is accommodated in the liquid tank 41. The second discharge port 44 of the liquid supply pump 43 is detachably connected to the drainage assembly 60. Specifically, since the liquid supply pump 43 is accommodated in the liquid tank 41, on the one hand, it can avoid the liquid supply pump 43 from occupying additional space, thereby improving the compactness of the humidifier 100. On the other hand, it is advantageous to control the second suction port of the liquid supply pump 43 below the height of the liquid surface, so that the second suction port can be completely immersed in the liquid, thereby ensuring that the liquid supply pump 43 can reliably inhale the liquid. Since the second discharge port 44 of the liquid supply pump 43 is detachably connected to the drainage assembly 60, the liquid supply pump 43 can be easily separated from the drainage assembly 60, and the tank body 40 and the liquid supply pump 43 can be easily cleaned separately.

[0108] In some embodiments, the liquid in the tank 40 is pumped to the top of the filter body 52 by the liquid supply pump 43 and then drips onto the filter body 52 to wet the filter body 52 .

[0109] In some embodiments, in combination Fig.15 and Fig.16 As shown, the drainage assembly 60 includes a flow channel plate 61, which is used to disperse the liquid. Specifically, the liquid is dispersed by the flow channel plate 61, and the liquid can flow to multiple positions of the filter body 52, which is beneficial to uniformly wet the entire filter body 52 and helps to improve the efficiency of humidification.

[0110] In some embodiments, the flow channel plate 61 is integrally connected to the filter support 51, so that a reliable connection is formed between the flow channel plate 61 and the filter support 51, which is conducive to improving the structural stability of the filter support 51. In other embodiments, the flow channel plate 61 is separately connected to the filter support 51. After the flow channel plate 61 is separated from the filter support 51, the filter body 52 can be installed on the filter support 51 from top to bottom, so that there are more optional installation methods between the filter body 52 and the filter support 51.

[0111] In some embodiments, in combination Fig.14 and Fig.17 As shown, the filter support 51 is used to abut against the inner periphery of the filter body 52, and the flow channel plate 61 is arranged at the top of the filter support 51, and the flow channel plate 61 at least partially protrudes outward from the filter support 51. Specifically, since the filter body 52 has a certain shrinkage, after the filter body 52 is sleeved to the outer peripheral side of the filter support 51, the filter support 51 abuts against the inner periphery of the filter body 52, so that the filter body 52 is maintained in a form with a larger perimeter, which is conducive to ensuring the air flow passing area of ​​the filter body 52. ​​In the case where the flow channel plate 61 is arranged at the top of the filter support 51, the height requirement of the filter support 51 can be reduced as much as possible, and at the same time, the flow channel plate 61 can be ensured to be higher than the filter body 52, so that the liquid can drip from the flow channel plate 61 to the filter body 52. ​​In addition, since the filter body 52 is on the outer peripheral side of the filter support 51, the flow channel plate 61 at least partially protrudes outward from the filter support 51, so that the flow channel plate 61 can allow the liquid to drip from directly above the filter body 52.

[0112] In some embodiments, in combination Fig.15 and Fig.16 As shown, the flow channel plate 61 is provided with a plurality of through holes 614 that penetrate the flow channel plate 61 vertically, and the plurality of through holes 614 are spaced apart from each other to disperse the liquid to different positions of the filter body 52. ​​Specifically, when the liquid flows over the flow channel plate 61, the liquid can pass through the flow channel plate 61 through the through holes 614 under the action of gravity. Since the plurality of through holes 614 correspond to different positions of the filter body 52, each part of the filter body 52 can contact with the dripping liquid, so that the filter body 52 is evenly moistened, which is conducive to improving the humidification efficiency.

[0113] In some embodiments, in combination Fig.16 and Fig.17 As shown, the drainage assembly 60 further includes a liquid supply conduit 62, one end of which is connected to the second discharge port 44 of the liquid supply pump 43, and the other end of which is connected to the flow channel plate 61. Specifically, the liquid supply conduit 62 extends vertically between the second discharge port 44 of the liquid supply pump 43 and the flow channel plate 61, so as to guide the liquid to flow from bottom to top to the flow channel plate 61. In one embodiment, one end of the liquid supply conduit 62 is nested with the second discharge port 44 of the liquid supply pump 43.

[0114] In some embodiments, in combination Fig.15 and Fig.16 As shown, an inner waterway 611 and an outer waterway 612 are formed on the flow channel plate 61. The outer waterway 612 surrounds the outer periphery of the inner waterway 611. The flow channel plate 61 has a retaining rib 613 for separating the outer waterway 612 from the inner waterway 611. A plurality of notches 615 are provided at intervals on the upper edge of the retaining rib 613. The notches 615 are used to allow liquid to flow between the inner waterway 611 and the outer waterway 612.

[0115] In one embodiment, in combination Figures 14 to 16 As shown, the outer waterway 612 is connected to the second discharge port 44 of the liquid supply pump 43, and the inner waterway 611 is connected to a plurality of through holes 614. Specifically, the other end of the liquid supply conduit 62 is inserted into the flow channel plate 61 and connected to the outer waterway 612. After the liquid level in the outer waterway 612 rises to a level higher than the lower edge of the notch 615, the liquid enters different positions of the inner waterway 611 through each notch 615. Since the plurality of through holes 614 are spaced apart along the inner waterway 611, the liquid entering the inner waterway 611 from any notch 615 will pass through the flow channel plate 61 through the nearest through hole 614, thereby ensuring that the liquid drips uniformly to each position of the filter body 52. ​​In one embodiment, the notches 615 are spaced uniformly along the outer circumference of the inner waterway 611. Further, there is at least one notch 615 corresponding to every two through holes 614. More specifically, along the outer circumference of the inner waterway 611, the notch 615 is arranged between two through holes 614.

[0116] In another embodiment, in combination Fig.16 and Fig.17 As shown, the inner waterway 611 is connected to the second discharge port 44 of the liquid supply pump 43, and the outer waterway 612 is connected to a plurality of through holes 614. Specifically, the other end of the liquid supply conduit 62 is inserted into the flow channel plate 61 and connected to the inner waterway 611. After the liquid level in the inner waterway 611 rises to be higher than the lower edge of the notch 615, the liquid enters different positions of the outer waterway 612 through each notch 615. A plurality of through holes 614 are distributed at intervals along the outer waterway 612.

[0117] In some embodiments, in combination Fig.15 and Fig.16 As shown, the flow channel plate 61 includes a bottom wall 616, an inner baffle wall 617 connected to the bottom wall 616, and an outer baffle wall 618 connected to the bottom wall 616. The baffle ribs 613 are arranged around the inner baffle wall 617 at intervals along the outer circumference, and the baffle ribs 613 and the inner baffle wall 617 respectively form the outer boundary and the inner boundary of the inner waterway 611. The outer baffle wall 618 is arranged around the baffle rib 613 at intervals along the outer circumference, and the outer baffle wall 618 and the baffle rib 613 respectively form the outer boundary and the inner boundary of the outer waterway 612.

[0118] In some embodiments, in combination Fig.15 and Fig.17 As shown, the drainage assembly 60 further includes a cover plate 63 connected to the flow channel plate 61, and the cover plate 63 is used to form the upper boundary of the inner waterway 611 and the outer waterway 612. Specifically, by using the cover plate 63 to form the upper boundary of the inner waterway 611 and the outer waterway 612, it is possible to prevent the liquid from overflowing from the edge of the flow channel plate 61 under the driving pressure of the liquid supply pump 43. Furthermore, a relatively sealed space is formed between the cover plate 63 and the flow channel plate 61, so that the liquid can be driven to flow to the through hole 614, thereby accelerating the speed of the liquid passing through the through hole 614.

[0119] In some embodiments, in combination Figure 8 As shown, the humidifier 100 further includes a driving body 381 connected to the body 30, and the driving body 381 is used to apply power to the liquid supply pump 43 to drive the liquid supply pump 43 to work. Specifically, the driving body 381 drives the impeller in the liquid supply pump 43 to rotate through a non-contact driving force.

[0120] In some embodiments, the driving body 381 is electrically connected to a signal source, and the signal source is used to adjust the driving body 381. In some embodiments, the driving body 381 is electrically connected to a power source, and the power source is used to provide power to the driving body 381.

[0121] In some embodiments, the driving body 381 enables the liquid supply pump 43 to work by transmitting a magnetic field. In one embodiment, the liquid supply pump 43 is a wireless pump, and a magnet connected to the impeller is provided in the liquid supply pump 43. The driving body 381 transmits an alternating magnetic field to the magnet, so that the magnet can drive the impeller to rotate under the action of a magnetic force. In another embodiment, the liquid supply pump 43 has a receiving coil, and the driving body 381 transmits an alternating magnetic field to the magnet, and the coil induces electric energy under the action of the magnetic field, and the electric energy is used to drive the impeller to rotate under the principle of a motor. In some embodiments, the driving body 381 includes a coil winding. More specifically, the driving body 381 is located directly below the liquid supply pump 43.

[0122] In some embodiments, in combination Figure 8 and Fig.13 As shown, the humidifier 100 further includes a bottom cover 38, which cooperates with the body 30 to form a space capable of accommodating the tank 40. Further, the bottom cover 38 is used to form the lower edge of the side port 35.

[0123] In one embodiment, the driving body 381 is connected to the bottom side of the bottom cover 38. In another embodiment, the driving body 381 is accommodated in the bottom cover 38, so that the bottom cover 38 can be used to provide waterproof protection for the driving body 381.

[0124] Since the liquid supply pump 43 is a wireless pump and forms a motion drive with the driving body 381 through a non-contact driving force, there is no direct connection. The liquid supply pump 43 does not need to be connected to a signal source or a power source. The disassembly of the liquid supply pump 43 will not be affected by the cables. The liquid supply pump 43 can be removed from the body 30 together with the tank body 40 for cleaning, so that bacteria grown due to the stored liquid or retained stains can be removed in time.

[0125] In some embodiments, in combination Fig. 22 As shown, the humidifier 100 includes: a body 30, a fan assembly 80, a filter assembly 50, a tank body 40 and a heating element 70. The humidifier 100 is provided with an air path 36 for connecting an air inlet 361 and an air outlet 362 of the humidifier 100. The fan assembly 80 is arranged in the body 30, and the fan assembly 80 is used to blow the airflow in the air path 36. The filter assembly 50 is arranged in the air path 36 and is used to filter and humidify the airflow. The tank body 40 is arranged in the body 30, and the tank body 40 is used to supply liquid to the filter assembly 50. The heating element 70 is arranged in the air path 36. The heating element 70 is located downstream of the filter assembly 50 and upstream of the fan assembly 80 along the airflow direction, and the heating element 70 is used to heat the airflow passing through the filter assembly 50.

[0126] Specifically, when the humidifier 100 is in operation, the fan assembly 80 operates, so that the airflow flows along the air path 36 between the air inlet 361 and the air outlet 362 of the humidifier 100, and a negative pressure is formed at the air inlet 361, and the airflow outside the humidifier 100 flows in from the air inlet 361. Since the tank body 40 supplies liquid to the filter assembly 50, the filter assembly 50 is in a moist state. And the filter assembly 50 is in the air path 36, and after passing through the filter assembly 50, the humidity of the airflow increases and the temperature decreases. After the airflow leaves the air outlet 362 and reaches the external environment of the humidifier 100, the humidity of the environment around the humidifier 100 can be increased. The heating element 70 radiates heat to the surroundings in the air path 36. Since the heating element 70 is located downstream of the filter assembly 50 and upstream of the fan assembly 80 along the air flow direction, the airflow can contact with the heating element 70 and absorb the heat generated by the heating element 70, and the temperature rises. The airflow is fully mixed when passing through the fan assembly 80, which improves the stability and uniformity of the airflow. The temperature of the airflow when leaving the air outlet 362 of the humidifier 100 can be increased, so as not to cause the temperature of the external environment of the humidifier 100 to drop too much, thereby avoiding the user feeling cold when using the humidifier 100.

[0127] In some embodiments, in combination Fig. 22 As shown, the direction of airflow in the air passage 36 is shown as path S1.

[0128] In some embodiments, in combination Figure 2 and Fig. 9As shown, the humidifier 100 further includes a ventilation plate 37, which is detachably covered on at least two sides of the body 30, and the air inlet 361 is provided on the ventilation plate 37. Specifically, the ventilation plate 37 is air-permeable, and by covering the body 30 with the ventilation plate 37, the filter assembly 50 is protected, and at the same time, the air permeability can be maintained, so that the external airflow can enter the body 30.

[0129] In some other embodiments, the fuselage 30 is provided with a ventilating plate 37, that is, the ventilating plate 37 is a component of the fuselage 30, and the air inlet 361 is provided on the ventilating plate 37. By covering at least two sides of the fuselage 30 with the ventilating plate 37, the area of ​​the air inlet 361 can be increased. In one embodiment, the fuselage 30 is covered with ventilating plates 37 on two adjacent sides. In some embodiments, the side shell can be replaced by the ventilating plate 37.

[0130] In some other embodiments, a single notch may be provided on the fuselage 30 as the air inlet 361 .

[0131] In some embodiments, the inner side of the air-permeable plate 37 is spaced from the filter body 52 of the filter assembly 50. Thus, a channel gap is formed between the inner side of the air-permeable plate 37 and the outer peripheral surface of the filter body 52, and the airflow can reach different positions of the outer peripheral surface of the filter body 52 through the channel gap, thereby helping to make the airflow pass through various positions of the filter body 52 uniformly along the circumferential direction.

[0132] In some embodiments, the tank 40 can hold liquid. Specifically, the liquid can be tap water or purified filtered water. The liquid can also be a mixture of water and an odor adjuster.

[0133] In some embodiments, in combination Fig. 22 As shown, on the projection surface that makes the air inlet 751 have the largest projection area, the projection area corresponding to the projection surface of the heating element 70 overlaps with the projection area of ​​the transition port 752 by at least 30% of the area. Specifically, since the airflow passes through the transition port 752 relatively concentratedly, when the heating element 70 is close to the transition port 752, it can help improve the heating efficiency of the airflow. And the projection area corresponding to the projection surface of the heating element 70 overlaps with the projection area of ​​the transition port 752 by at least 30% of the area, thereby further improving the heating efficiency of the airflow. In the direction perpendicular to the projection surface, the heating element 70 is kept at a distance from the transition port 752, which can avoid the heating element 70 from causing excessive obstruction to the airflow.

[0134] In one embodiment, for the projection plane that enables the air inlet 751 to have the maximum projection area, the projection plane is parallel to the plane where the edge of the air inlet 751 is located.

[0135] In some embodiments, the heating element 70 is an electric heating device. Specifically, the heating element 70 is one or more of a heating resistor, an electric heating ceramic, and an electric semiconductor. In one embodiment, the heating element 70 is a PTC ceramic element to help achieve constant temperature control of the heating element 70.

[0136] In some embodiments, in combination Fig. 22 As shown, the humidifier 100 also includes a partition 71 provided with a plurality of through slots 72. The partition 71 is arranged at a position close to the air inlet 751. The heating element 70 is arranged on a side of the partition 71 close to the transition port 752. Specifically, since the partition 71 is provided with a plurality of through slots 72, the airflow in the air path 36 can pass through the partition 71. When the partition 71 is close to the air inlet 751 and the heating element 70 is arranged on a side of the partition 71 close to the transition port 752, the partition 71 can limit the user's hand from entering the space between the partition 71 and the wind cover 75, thereby preventing the user's hand from contacting the heating element with a higher temperature.

[0137] In one embodiment, the transition port 752 is located above the partition 71 , and the heating element 70 is connected to the upper side of the partition 71 , so that the partition 71 can support the heating element 70 .

[0138] In some embodiments, in combination Fig. 22 and Fig.23 As shown, the humidifier 100 also includes a holder 73, and the holder 73 is connected to the side of the partition 71 close to the transition port 752. The holder 73 is clamped to the heating element 70 to fix the heating element 70 to the partition 71. Specifically, by connecting the holder 73 to the side of the partition 71 close to the transition port 752, the user can be prevented from contacting the heating element 70. At the same time, the use of the holder 73 to clamp the heating element 70 can simplify the assembly of the heating element 70 and improve the assembly efficiency of the humidifier 100. In one embodiment, the holder 73 includes a fixing portion 731 connected to the partition 71 and an ear portion 732 connected to the fixing portion 731, and the ear portions 732 are respectively connected to the opposite sides of the fixing portion 731. The heating element 70 is installed between a plurality of opposite ear portions 732. One end of the ear portion 732 away from the fixing portion 731 is hook-shaped, and after the heating element 70 enters between the ear portions 732, the end of the ear portion 732 limits the heating element 70. More specifically, the fixing portion 731 can be one or more, as long as the ear portion 732 can be fixed relative to the partition 71.

[0139] In some embodiments, in combination Fig. 22As shown, the humidifier 100 further includes a temperature detection member 85. The temperature detection member 85 is disposed downstream of the air path 36 relative to the heating member 70. Specifically, by using the temperature detection member 85 to detect the temperature of the airflow downstream of the heating member 70, the temperature condition of the airflow after absorbing the heat of the heating member 70 can be determined. In some embodiments, the temperature detection member 85 is a thermistor, a thermocouple, or other temperature detection device.

[0140] In some embodiments, in combination Fig. 22 As shown, the temperature detection member 85 is connected to the fan bracket 82 and is close to the air outlet 362 of the humidifier 100. Specifically, when the airflow passes through the fan assembly 80, the airflow collides violently with the centrifugal impeller 81, and at the same time, each part of the airflow undergoes a process of dispersion and re-convergence, so that the temperature of the airflow is more balanced. When the temperature detection member 85 is close to the air outlet 362 of the humidifier 100, the temperature detection member 85 can be used to detect a stable and referenceable temperature.

[0141] In some embodiments, in combination Fig. 22 As shown, the temperature detection member 85 is installed on one of the fixing pieces 822. Specifically, the sensing end of the temperature detection member 85 faces the upstream of the air path 36.

[0142] In some embodiments, in combination Fig.21 and Fig. 22 As shown, the humidifier 100 also includes an interactive module 74. The interactive module 74 is electrically connected to the temperature detection component 85, and the interactive module 74 is used to output a feedback signal reflecting the temperature detection value of the temperature detection component 85. Specifically, an input end of the interactive module 74 is connected to the temperature detection component 85 to receive the temperature detection value of the temperature detection component 85. The interactive module 74 outputs a feedback signal wirelessly or wired, and the content of the feedback signal includes the temperature detection value. In one embodiment, the feedback signal is used to be sent to the cloud or other data storage terminal to record the feedback signal and provide it for user access and query. In another embodiment, the feedback signal is used to be sent to a mobile terminal for the user to view the temperature detection value.

[0143] In some embodiments, the interactive module 74 is electrically connected to the heating element 70, and the interactive module 74 is used to adjust the heating power of the heating element 70 according to the received adjustment instruction. Specifically, the user can input the adjustment instruction to the interactive module 74 through the button of the humidifier 100 or the terminal device according to the requirement for the ambient temperature. In some embodiments, the interactive module 74 adjusts the heating power of the heating element 70 according to the size relationship between the required temperature in the adjustment instruction and the temperature detection value.

[0144] More specifically, when the required temperature is higher than the temperature detection value, the interactive module 74 adjusts the heating power of the heating element 70 to increase the heating power. When the required temperature is lower than the temperature detection value, the interactive module 74 adjusts the heating power of the heating element 70 to decrease the heating power.

[0145] In some embodiments, in combination Figure 6 and Figure 7 As shown, a supply port 914 is provided at the bottom of the water tank body 91 , and the supply port 914 is used to discharge the liquid in the storage cavity 911 to the liquid tank 41 of the tank body 40 .

[0146] In some embodiments, in combination Figure 6 and Figure 7 As shown, the input interface 921 is provided on the water tank body 91 and is lower than the filling port 912. The injection port 922 is located at the upper part of the storage cavity 911 and is higher than the input interface 921. The angle between the direction from the filling port 912 to the bottom surface 913 and the opening direction of the injection port 922 is not greater than 120 degrees. Specifically, since the injection port 922 is located at the upper part of the storage cavity 911 and is higher than the input interface 921, and the liquid can only be connected to the input interface 921 through the drainage piece 92, when the liquid level in the water tank body 91 is lower than the injection port 922, it can prevent the liquid in the water tank body 91 from flowing back into the injection port 922, thereby preventing the liquid from flowing back and leaking through the drainage piece 92. At the same time, since the angle between the direction from the inlet 912 to the bottom surface 913 and the opening direction of the injection port 922 is no more than 120 degrees, when the liquid is ejected from the injection port 922 under the pressure of the liquid replenishment pump 20, since the injection port 922 is not vertically upward, the liquid will not flow back from the injection port 922, thereby preventing water from flowing out from the bottom of the water tank body 91.

[0147] In some embodiments, in combination Figure 6 and Figure 7 As shown, the flow guide member 92 includes a positioning joint 923 and a main guide pipe 924. The positioning joint 923 is connected to the water tank body 91. The main guide pipe 924 is used to form the boundary of the flow channel. One end of the main guide pipe 924 is connected to the input interface 921, and the other end of the main guide pipe 924 is nested with the positioning joint 923, wherein one end of the main guide pipe 924 itself can be used as the input interface 921 or one end of the main guide pipe 924 can be connected to the input interface 921, and the injection port 922 is provided at the positioning joint 923. Specifically, the main guide pipe 924 forms the boundary of the flow channel. Since the positioning joint 923 is connected to the water tank body 91, the positioning joint 923 is stable relative to the water tank device 90. When the other end of the main guide pipe 924 is nested with the positioning joint 923, the positioning joint 923 can limit the position of the other end of the main guide pipe 924, which is conducive to maintaining a stable shape of the flow channel. Since the injection port 922 is disposed on the positioning joint 923 , the position of the injection port 922 can also be kept stable relative to the water tank body 91 .

[0148] In some embodiments, in combination Figure 6 and Figure 7 As shown, the main conduit 924 and the positioning joint 923 are both disposed in the storage cavity 911. Specifically, by disposing the main conduit 924 and the positioning joint 923 in the storage cavity 911, the compactness of the structure of the water tank device 90 can be improved, and the main conduit 924 or the positioning joint 923 can be prevented from being hit.

[0149] In some embodiments, in combination Figure 6 and Figure 7 As shown, the angle between the direction in which the main guide tube 924 extends upward and the direction in which the storage chamber 911 extends upward is less than 30 degrees. The positioning joint 923 extends upward, for example, vertically upward or obliquely upward, and the injection port 922 is arranged on the side wall of the positioning joint 923. Specifically, in the case where the angle between the direction in which the main guide tube 924 extends upward and the direction in which the storage chamber 911 extends upward is less than 30 degrees, the main guide tube 924 can extend from the input interface 921 to the positioning joint 923 with a shorter length, thereby facilitating the reduction of the length of the main guide tube 924. Furthermore, in the case where the main guide tube 924 is arranged in the storage chamber 911, the storage chamber 911 can have more liquid holding space. In some embodiments, the direction in which the storage chamber 911 extends upward can be understood as the direction from the bottom surface 913 toward the injection port 912.

[0150] In some embodiments, in combination Figure 6 and Figure 7 As shown, the positioning joint 923 extends upward, and the injection port 922 is set on the side wall of the positioning joint 923, so that the opening direction of the injection port 922 will not be vertically upward, thereby preventing the liquid in the injection port 922 from flowing back to the bottom of the water tank body 91 along the main guide pipe 924.

[0151] In some embodiments, in combination Figure 6 and Figure 7 As shown, the top end of the positioning joint 923 is connected to the inner side of the top wall of the storage chamber 911, and the bottom end of the positioning joint 923 is connected to the top end of the main guide tube 924. Specifically, the top wall of the storage chamber 911 can be arranged adjacent to the injection port 912. When the top end of the positioning joint 923 is connected to the inner side of the top wall of the storage chamber 911 and the injection port 922 is arranged on the positioning joint 923, the injection port 922 can be positioned closer to the injection port 912, or the injection port 922 can be positioned closer to the top wall of the storage chamber 911, so as to facilitate the liquid to be sprayed into the storage chamber 911 from top to bottom.

[0152] In some embodiments, the flow guide 92 includes a main guide pipe 924, which is used to form the boundary of the flow channel. One end of the main guide pipe 924 is connected to the input interface 921. The main guide pipe 924 is bent near a section of the inlet 912. The injection port 922 is arranged at the end of a section of the main guide pipe 924 close to the inlet 912. Specifically, the main guide pipe 924 is bent near a section of the inlet 912, so that the direction of the injection port 922 can be adjusted, so that the injection port 922 is as close to the bottom surface 913 of the storage cavity 911 as possible, and the injection port 922 is prevented from flowing back to the bottom of the water tank body 91 through the main guide pipe 924. In some embodiments, the main guide pipe 924 is arranged inside the storage cavity 911 to improve the compactness of the water tank body 91.

[0153] In some other embodiments, the main conduit 924 is disposed outside the storage cavity 911 so that the storage cavity 911 has a larger remaining space. Specifically, the main conduit 924 includes a first segment, a transition segment, and a second segment. The transition segment is connected between the first segment and the second segment. The first segment is outside the storage cavity 911 and is connected to the input interface 921. The second segment is inside the storage cavity 911, and the injection port 922 is formed in the second segment. In one embodiment, the transition segment can be a self-filling inlet 912 to enter the storage cavity 911. In another embodiment, the transition segment can pass through the wall of the water tank body 91 and enter the storage cavity 911.

[0154] In some embodiments, in combination Figure 4 , Fig.13 As shown, a bottom groove 31 is also provided in the fuselage 30, and the bottom groove 31 is used to accommodate the tank body 40. At least a part of the liquid groove 41 of the tank body 40 is provided below the water tank device 90, and the liquid groove 41 is adjacent to the first supporting surface 32, and the liquid groove 41 is provided in a concave position relative to the first supporting surface 32. The first supporting surface 32 is provided in a slanting downward direction toward the liquid groove 41. Specifically, since the height of the liquid groove 41 is lower than that of the first supporting surface 32, and the first supporting surface 32 is provided in a slanting downward direction toward the liquid groove 41. Therefore, when a small amount of liquid accidentally flows down from the fixed joint 24 to the first supporting surface 32, the convex edge portion 321 can restrict the liquid from flowing in any direction around, so that the liquid is near the fixed joint 24, and the first supporting surface 32 provided in a slanting downward direction can guide the liquid to flow into the liquid groove 41, so as to avoid the liquid from continuously accumulating on the first supporting surface 32.

[0155] In some embodiments, when the humidifier 100 is not provided with a removable tank body 40, the boundary of the liquid tank 41 can also be formed by the inner wall surface of the body 30, and the purpose or structure of the liquid tank 41 is as described above. Further, the inner wall surface of the body 30 can also be used to form the first support surface 32.

[0156] In some embodiments, in combination Fig.21 and Fig. 22 As shown, the humidifier 100 also includes a hood 75, which is provided with an air inlet 751 and a transition port 752 that are connected. The air inlet 751 faces the upper end of the filter assembly 50, and the transition port 752 is connected to the fan assembly 80. The heating element 70 is arranged in the hood 75. Specifically, the hood 75 forms a boundary of one section of the wind path 36, and the air flow flows in the hood 75 from the air inlet 751 to the transition port 752. The air inlet 751 faces the upper end of the filter assembly 50, and the transition port 752 is connected to the fan assembly 80, so that the airflow leaving the upper end opening of the filter assembly 50 can be maximized and guided to the fan assembly 80 by using the shape difference between the upper end opening of the filter assembly 50 and the input port of the fan assembly 80. In one embodiment, the shape of the air inlet 751 corresponds to the shape of the upper end opening of the filter assembly 50, and the shape of the transition port 752 corresponds to the shape of the input port of the fan assembly 80.

[0157] Specifically, since the filter assembly 50 is spaced between the wind hood 75 and the tank body 40, when the heating element 70 is disposed in the wind hood 75, the heating element 70 maintains a certain distance from the tank body 40, thereby preventing the heating element 70 from being immersed in liquid.

[0158] In some embodiments, the wind hood 75 narrows along the direction from the air inlet 751 to the transition port 752. Specifically, in order to improve the efficiency of filtering and humidification, the filter body 52 of the filter assembly 50 is generally maintained in a state with a larger circumference, so the width or length of the upper opening of the filter body 52 is larger. However, since the centrifugal fan structure requires circumferential spacing inside, the width of the input port of the fan assembly 80 is relatively small. By narrowing the wind hood 75 along the direction from the air inlet 751 to the transition port 752, the wind hood 75 can adapt to the size difference between the upper opening of the filter body 52 and the input port of the fan assembly 80, and stably guide the airflow from the upper opening of the filter body 52 to the input port of the fan assembly 80.

[0159] In some embodiments, in combination Fig.21 and Fig. 22 As shown, the fan assembly 80 includes an outer cover 84 connected to the transition port 752. At least one of the wind cover 75 and the outer cover 84 is connected with a flange portion 753. The flange portion 753 is arranged around the circumference of the transition port 752. Specifically, by arranging the flange portion 753 around the circumferential edge of the transition port 752, the airflow leaving the wind cover 75 can be prevented from diffusing in the radial direction, so that the airflow can stably enter the outer cover 84.

[0160] In other embodiments, in combination Fig. 22 and Fig.23As shown, the fan assembly 80 includes a centrifugal impeller 81, which disperses the airflow toward the periphery to the inner wall surface of the outer cover 84 during operation. The port of the centrifugal impeller 81 is nested with the flange portion 753, so that the airflow first completely enters the centrifugal impeller 81, and then is transported by the centrifugal impeller 81 to the inner wall of the outer cover 84 along the circumferential direction.

[0161] In some embodiments, in combination Fig. 22 As shown, the fan assembly 80 includes a fan bracket 82 and a fan body 83 connected to the fan bracket 82. Specifically, the output shaft 831 of the fan body 83 is connected to the centrifugal impeller 81 to drive the centrifugal impeller 81 to rotate. In one embodiment, the fan body 83 is a motor. The fan bracket 82 is used to support the fan body 83. In one embodiment, the fan bracket 82 is connected between the fan body 83 and the outer cover 84. In one embodiment, most of the fan body 83 is accommodated in the fan bracket 82, and the output shaft 831 of the fan body 83 extends outside the fan bracket 82, so that the fan bracket 82 plays a protective role for the fan body 83.

[0162] Furthermore, combined with Fig. 22 As shown, the fan bracket 82 includes a middle shell 821 and a plurality of fixing plates 822 connected to the outer periphery of the middle shell 821. The fan body 83 is accommodated in the middle shell 821. Further, the fixing plates 822 are connected between the outer periphery of the middle shell 821 and the inner periphery of the outer cover 84. The thickness direction of the fixing plates 822 is perpendicular to the airflow direction to reduce the wind resistance of the fixing plates 822.

[0163] In some embodiments, in combination Fig.24 As shown, the translational carrier 001 is a cleaning robot having both the function of house cleaning and the function of automatically adding water to the humidifier 100. The translational carrier 001 is pre-bound to the humidifier 100 through an APP or the like. It can automatically take water from equipment such as a cleaning base station and a water changing base station, or transport and deliver water to the humidifier 100 according to the user's operation / settings in the APP, or when the humidifier 100 detects a water shortage.

[0164] In some embodiments, the liquid transported by the translational carrier 001 is clean water.

[0165] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0166] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
