[0070] In this embodiment, the sealing portion 1211 and the fixing portion 1212 are arranged in a W shape, so that the portion of the sealing portion 1211 inserted into the drain pipe 112 can be maximized, thereby improving the sealing effect of the opening of the drain pipe 112.

[0071] In some embodiments, optionally, the sealing portion 1211 includes a sealing protrusion 1213, the end of which can extend into the drain pipe 112, and the sealing member 12 also includes: a first guide structure 1214, which is arranged at the end of the sealing protrusion 1213; and a second guide structure 1215, which is arranged on the fixing portion 1212 and is located at the opening of the accommodating space 1216.

[0072] In this embodiment, the sealing portion 1211 includes a sealing protrusion 1213, the end of which can extend into the drain pipe 112 to seal the drain pipe 112. The blocking member 12 also includes a first guide structure 1214 and a second guide structure 1215. The first guide structure 1214 is provided at the end of the sealing protrusion 1213, so that when the sealing protrusion 1213 is inserted into the drain pipe 112, it can be guided by the first guide structure 1214, thereby facilitating the installation of the blocking member 12 and improving installation efficiency. At the same time, a second guide structure 1215 can also be provided on the fixing portion 1212 located at the opening of the accommodating space 1216, so that the drain pipe 112 can be guided by the second guide structure 1215, thereby facilitating the detachable installation of the blocking member 12 on the drain pipe 112.

[0073] In some embodiments, optionally, the first guide structure 1214 and the second guide structure 1215 may be chamfered or rounded.

[0074] In some embodiments, optionally, the blocking member 12 further includes: an outer flange structure 123 , which is provided on the fixing portion 1212 and located at the opening of the accommodating space 1216 , and is used to limit the fastener 122 .

[0075] In this embodiment, an outer flange structure 123 can be provided on the fixing portion 1212, and the outer flange structure 123 can be provided at the opening of the accommodating space 1216, so that the fastener 122 can be limited by the outer flange structure 123 to prevent the fastener 122 from moving or falling off.

[0076] In some embodiments, the fastener 122 optionally includes a clamp or an elastic sleeve capable of adjusting the tightness.

[0077] In this embodiment, the fastener 122 can be set as a clamp, an elastic sleeve that can adjust the tightness, etc. The clamp and the elastic sleeve have a simple structure, are easy to install and disassemble, have a good fastening effect, and are low in cost.

[0078] In some embodiments, optionally, as Figure 3 As shown, the clamp includes: a fastening ring 1221, which is sleeved on the outside of the fixing portion 1212; two lugs 1222, which are fixedly connected to the fastening ring 1221, and the two lugs 1222 can approach or move away from each other along the circumferential direction of the fastening ring 1221 to increase or decrease the inner diameter of the fastening ring 1221; the two lugs 1222 and the fastening ring 1221 are an integrated structure, or the two lugs 1222 and the fastening ring 1221 are detachably connected.

[0079] In this embodiment, the clamp includes a fastening ring 1221 and two lugs 1222. The fastening ring 1221 is sleeved on the outside of the fixing portion 1212, and the two lugs 1222 are fixedly connected to the fastening ring 1221, and as shown in FIG. Figure 3 As shown, the two lugs 1222 can move closer to or farther from each other along the circumferential direction of the fastening ring 1221, thereby increasing or decreasing the inner diameter of the fastening ring 1221. This allows the user to increase the radius of the fastening ring 1221 when installing or removing the fastening ring 1221 to facilitate installation. When the fastening ring 1221 clamps the seal 121, the radius of the fastening ring 1221 can be reduced, thereby clamping the seal 121 to ensure the sealing effect of the seal 121. In order to facilitate processing and to improve the stability of the clamp, the two lugs 1222 and the fastening ring 1221 can be configured as an integrated structure. Of course, the two lugs 1222 and the fastening ring 1221 can also be configured as a detachable connection.

[0080] According to an embodiment of the first aspect of the present invention, a humidifier 1 is provided, which is designed with a drain plug (sealing member 12) on the back or bottom of the entire machine. When the user needs to drain the water, he pinches the iron hoop (fastener 122) on the rubber plug (seal 121) with both hands to loosen the rubber plug, allowing the water in the water tank 11 to flow out from the gap (drain hole 111).

[0081] Specifically, a gap can be first opened at the lowest point of the water level at the bottom of the water tank 11 to meet the needs of assembling the plug assembly (sealing member 12). The position of the gap only needs to be at the lowest point of the water level, and can be on the side of the water tank 11 or at the bottom of the water tank 11. At the same time, in order to facilitate the residual water inside the water tank 11 to flow to the gap position, the bottom plane of the water tank 11 is designed with an inclination angle, and the whole is an inclined plane to ensure that water can flow out more easily during drainage. The inclined plane needs to ensure that the lowest point of the inclination angle is the gap position. The end of the gap is equipped with a plug assembly, which includes a rubber plug (seal 121) and an iron hoop (fastener 122). In order to prevent the plug assembly from slipping out during transportation or handling, a circle of ribs is added to the outer edge of the cylindrical end to increase the interference fit and reduce the risk of falling off.

[0082] The overall design of the rubber plug is as follows Figure 2 The groove shape shown has a protrusion inside, and the end of the protrusion has a large C angle for easy assembly. The protrusion and the water tank 11 are interference fit. When the protrusion is inserted into the circular notch, the interference position will be squeezed and deformed, allowing full contact between the rubber plug on the inner wall of the notch of the water tank 11 to avoid water leakage.

[0083] The outer side of the plug is also designed with a deep flange (fixing portion 1212), with a large C-angle at the end to facilitate assembly. The outer side of the flange is clamped with an iron hoop. When assembled, the iron hoop squeezes the outer flange of the plug and deforms it, allowing the inner side of the outer flange to fully contact the outer surface of the cylindrical notch of the water tank 11, forming an interference fit.

[0084] At the same time, the raised surface inside the plug is in full contact with the inner surface of the cylindrical notch of the water tank 11, with interference fit and extrusion deformation. Through extrusion on both sides, double sealing is achieved to ensure that there will be no water leakage during normal use.

[0085] During normal assembly, the rubber plug and the iron hoop are separate. The user first squeezes the rubber plug to install it to the default position, and then uses his fingers to pinch the iron hoop to increase the inner diameter of the iron hoop, making it easier to assemble it into the innermost part of the rubber plug.

[0086] Once fully assembled, the hoop is released, causing it to rebound and deform the rubber plug. To disassemble, the user first pinches the hoop, removes it, and then removes the rubber plug. The hoop has two stress-bearing locations (two lugs 1222). When the user squeezes, the circle expands, and when the user replaces it, the circle shrinks.

[0087] In some embodiments, optionally, as Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the humidifier 1 further includes an air inlet grille 15 which at least partially surrounds the outer side of the water tank 11 , and an escape hole is provided on the air inlet grille 15 corresponding to the drainage hole 111 .

[0088] In this embodiment, an air inlet grille 15 may also be provided, at least partially surrounding the outside of the water tank 11. This arrangement not only allows air to flow from the outside of the humidifier 1 into the interior, achieving air circulation and humidification, but also protects the water tank 11 from damage. Furthermore, to avoid the drain hole 111, a clearance hole may be provided on the air inlet grille 15 at a location corresponding to the drain hole 111.

[0089] Because the air inlet grille 15 at least partially surrounds the outside of the water tank 11, when mounted on the water tank 11, the air inlet grille 15 can protrude from the water tank 11. That is, the air inlet grille 15 can be positioned higher than the water tank 11. In this case, if water is drained from the upper portion of the water tank 11, the water will disperse along the air inlet grille 15, hindering the drainage of the water in the water tank 11. The provision of the drain hole 111 for drainage prevents water from spilling along the air inlet grille 15 when pouring water. Alternatively, the air inlet grille 15 and the water tank 11 can both be mounted on the humidifier body 13, with a gap reserved between them to allow air to enter, thereby increasing the air intake efficiency of the air inlet grille 15.

[0090] In some embodiments, optionally, the humidifying element 14 includes a wet curtain 141, and the humidifier 1 further includes: a bottom component 16, including a water tank 11, a wet curtain bracket 161 and a wet curtain 141, wherein the wet curtain bracket 161 is installed on the water tank 11 and protrudes from the water tank 11, the wet curtain 141 is installed on the wet curtain bracket 161, a portion of the air inlet grille 15 is installed outside the water tank 11, a portion of the air inlet grille 15 is installed outside the wet curtain bracket 161, an air inlet hole 151 is provided on the air inlet grille 15, and the air inlet hole 151 is at least partially arranged around the outside of the water tank 11; an upper component 17, including a shell component 171 and a fan component 172, one end of the shell component 171 is detachably connected to the wet curtain bracket 161, and the fan component 172 is installed It is installed in the shell component 171, and an air outlet 1711 is provided on the end of the shell component 171 away from the bottom component 16; wherein, the air inlet 151 and the air outlet 1711 are connected to form an air duct 173, the fan component 172 and the wet curtain 141 are located in the air duct 173, and the fan component 172 can allow the air outside the air inlet grille 15 to enter through the air inlet 151, and pass through the wet curtain 141 and then be discharged from the air outlet 1711; the power interface 18 is installed on the upper component 17; the first connector 19 is provided on the shell component 171 and is connected to the power interface 18; the second connector 20 is provided on the wet curtain bracket 161, and when the shell component 171 is connected to the wet curtain bracket 161, the first connector 19 and the second connector 20 are electrically connected.

[0091] In this embodiment, the humidifier 1 further includes a bottom assembly 16 and an upper assembly 17. That is, the humidifier 1 is a two-part structure. Therefore, when cleaning the humidifier 1, the upper assembly 17 can be removed to clean the bottom assembly 16 as a whole. In this way, the dirt on the bottom assembly 16 can be thoroughly cleaned, thereby improving the cleaning effect.

Part of the air inlet grille 15 is mounted outside the water tank 11, and part of the air inlet grille 15 is mounted outside the wet curtain bracket 161. The air inlet grille 15 is provided with an air inlet hole 151. Therefore, the air entering through the air inlet hole 151 will pass through the wet curtain 141 into the interior of the humidifier 1 and then be discharged, thereby achieving humidification of the air. Furthermore, since the air inlet holes 151 are at least partially arranged around the outside of the water tank 11, air can also enter through the air inlet holes 151 on the outside of the water tank 11, thereby increasing the air inlet area of the air inlet grille 15. Since the bottom assembly 16 includes the water tank 11, the wet curtain bracket 161, and the wet curtain 141, when cleaning the humidifier 1, the water tank 11, the wet curtain bracket 161, and the wet curtain 141 can be removed for cleaning. The upper assembly 17 includes a housing assembly 171 and a fan assembly 172. One end of the housing assembly 171 is detachably connected to the wet curtain bracket 161.

The fan assembly 172 allows air from outside the air inlet grille 15 to enter through the air inlet 151, pass through the wet curtain 141, and be discharged from the air outlet 1711, thereby achieving air circulation and humidification. The power interface 18 is mounted on the upper assembly 17, thereby preventing water from entering the power interface 18 when cleaning the bottom assembly 16 of the humidifier 1. The first connector 19 is arranged on the housing assembly 171 and connected to the power interface 18. The second connector 20 is arranged on the wet curtain bracket 161.

The bottom component includes a wet curtain assembly, a coupler B terminal (second connector), a wet curtain bracket, a wiring cover, a water pump mounting bracket, a float mounting bracket, a water level detection board, a waterproof silicone, a water tank and casters. The following is a detailed introduction to the structure and installation of each component:

[0098] 1. Cover: This is the display window on the top of the machine. It features a semi-transparent black exterior and an overall curved, hemispherical shape. It integrates with the light shield and water level indicator, providing light and text to indicate the remaining water level in the water tank. It is secured to the air outlet grille with snap-fits around the edges, and locked to the motor bracket with four screws at the bottom.

[0099] 2. Air outlet grille: This is the air outlet of the machine. Its overall appearance is curved, with a central groove. This, combined with the raised shape of the cover, guides users to add water to the center groove at the top of the machine. The air outlet grille is secured to the motor bracket with four screws around its perimeter and to the cover with a buckle in the center.

[0100] 3. Top cover: The operating button component of the machine is installed on the air outlet grille and the upper shell through a buckle and slot structure. At the same time, a complete long stop structure is designed at the assembly position of the top cover and the air outlet grille to ensure that when the user adds water, the water will not flow through the installation gap to the outside of the air duct system and wet the circuit board outside the air duct system.

[0101] 4. Light shield: It is fixed to the cover plate with screws and four clips. The water level display panel is installed on the bottom. The rib structure of the light shield ensures that the light on the water level display panel will not be distorted. At the same time, the light shield is designed with a flanged rib structure around the perimeter to ensure that when the light shield is installed on the cover plate, the flanged rib structure can press the conductive sponge tightly, ensuring full contact between the conductive sponge and the cover plate.

[0102] 5. Water Level Display Board: This circuit board is primarily divided into two sections: an LED display area in the center and aluminum foil areas at the four corners. The contact between the aluminum foil and the conductive sponge creates a sensor system. When water is added from the top, the sensor detects the flow of water over the conductive sponge, converting it into an electrical signal that is transmitted to the main control board. The main control chip analyzes the signal and sends a command to the motor, immediately stopping it to prevent the impeller from hitting water during the filling process. A circle of LED lights in the center reminds the user of the water level in the tank. This section is connected to the main control board via a wiring harness.

[0103] 6. Conductive sponge: The conductive sponge has glue on the back and is pasted to the inside of the cover. At the same time, the bottom is pressed by the rib structure of the light shield, forming a passage with the inner surface structure of the light shield, the four corners of the water level display board, the position with aluminum foil and the bottom part of the conductive sponge to form a sensor sensing system.

[0104] 7. Upper Shell: This is the protective outer shell of the head of the machine and is also the most important exterior surface of the machine. The top of the upper shell fits into the slots and buckles of the top cover, and the bottom is fixed with screws to the fixing plate, protecting the entire head of the machine.

[0105] 8. Sealing silicone: Installed inside the annular groove of the motor bracket, fixed by screws between the cover plate and the motor bracket, causing the silicone to deform to ensure the seal between the cover plate and the motor bracket installation position, ensuring that when the user adds water, the water will not flow into the motor bracket and cause motor failure.

[0106] 9. Motor bracket: The mounting component of the motor, the top is fixed to the cover and the air outlet grille respectively, the bottom is fixed to the air duct, and there are guide vanes designed around it, forming part of the entire air duct system.

[0107] 10. Motor: The component that provides power to the entire machine. It is connected to the main control board through a wiring harness, provides current, and drives the wind wheel to rotate.

[0108] 11. Wind wheel: installed on the motor, rotates with the motor to form airflow, and promotes the air circulation inside and outside the humidifier 1.

[0109] 12. Air duct: An important component of the air duct system. Its interior is part of the air flow path, and its exterior is equipped with coupler A terminals, DC sockets, main control boards and other important electrical components.

[0110] 13. Coupler A Terminal: Since the entire unit consists of two detachable parts, the external power interface is located in the upper housing. To power the lower housing assembly and meet functions such as water pump filling and water level detection, the coupler's A and B terminals are required for power and communication with the electronic control. Terminal A is fixed to the air duct with screws. A notch in the fixing plate allows the steel pin on terminal A to mate with terminal B.

[0111] 14. Fixing plate: The base of the upper shell assembly of the fuselage head, connected to the upper shell and the air duct by screws. It is also the key component to realize the assembly guide of the fuselage head and the bottom. There are four grooves at the four corners of the bottom, and the four grooves are used to complete the alignment of the coupler and the installation of the machine.

[0112] 15. Sealing sponge: a circular structure with adhesive on one end, which is tightly attached to the back of the fixed plate. When the upper shell assembly and the lower shell assembly are installed in place, the sealing sponge completes the sealing of the joint to ensure the airtightness of the entire air intake system.

[0113] 16. DC socket: It is installed on the outside of the air duct through a card slot structure, and the bottom is limited by a fixed plate. It serves as the connection port between the whole machine and the external power supply. One end is connected to the adapter and the other end is connected to the main control board. The adapter is connected to the external mains power to ensure that the machine is powered.

[0114] 17. Main Control Board: Installed outside the air duct via a slotted structure, with a fixed plate at the bottom to limit its position, this board is the brain of the entire machine. The chip on the main control board controls its operation. It connects to the coupler, motor, front display, top water level display panel, top keypad, and other sensor wiring harnesses to complete current transmission and communication.

[0115] 18. Front display assembly: The front display part of the whole machine is connected to the main control board by a wiring harness. It serves as the most important display window of the entire machine, displaying the humidity and the current working mode of the machine.

[0116] 19. Top button panel: fixed on the back of the top cover, connected to the main control board through a wiring harness, and is the operating button part of the entire machine.

[0117] 20. Clamps: These are mounted on the mounting plate, one on each side of the machine. They have two hooks on the bottom. When the machine is fully assembled, the springs expand and contract, allowing the two hooks to engage the air intake grille, connecting the upper and lower housings. The outer surface of the clamps is concave in half and convex in half. The user holds the concave portion with both hands to carry the machine. Pressing the convex portion releases the springs, releasing the hooks that hold the air intake grille, allowing the upper and lower housings to be separated and disassembled.

[0118] 21. Wet Curtain Assembly: This is the humidifying component of the entire machine, placed on the wet curtain bracket. It houses an internal water supply pipe, which pumps water from the pump to the top of the wet curtain assembly. Water is then diverted there, evenly wetting the circular wet curtain. To ensure proper alignment between the wet curtain assembly and the wet curtain bracket, a straight edge is designed at the bottom of the circular wet curtain assembly. This straight edge, positioned between the wet curtain bracket and the wet curtain assembly, ensures that the wet curtain assembly's water supply pipe hole aligns with the water inlet between the wet curtain brackets.

[0119] 22. Coupler B terminal: One of the components of the wet curtain bracket assembly, fixed to the convex part of the wet curtain bracket by screws. At the same time, the contact surface of the entire coupler A terminal and coupler B terminal is higher than the highest surface of the wet curtain assembly.

[0120] 23. Wet curtain bracket: The core component of the wet curtain bracket assembly, with four convex bumps on the top, which cooperate with the four groove structures on the bottom surface of the fixed plate, that is, the guide structure for the upper and lower shell components to be installed in an aligned manner. At the same time, one of the convex bumps is installed with a coupler B terminal inside to achieve communication between the upper and lower components. In addition, the middle of the other two convex bumps is hollowed out and used as handles to facilitate the user to lift the entire wet curtain bracket assembly. There is a circle of flange at the top of the wet curtain bracket, which is mounted on the inner flange of the air inlet grille. In order to achieve the installation limit of the wet curtain bracket, a convex bump structure is designed on the back of the top flange of the wet curtain bracket. At the same time, a through hole is opened at the corresponding position of the air inlet grille. When assembling the upper and lower parts, the wet curtain bracket is limited by the guidance and positioning of the convex bump.

[0121] 24. Wiring Cover: A component of the wet curtain bracket assembly, the wiring harness connecting the coupler's B terminal to the water level detection board in the lower housing assembly is connected to complete communication. The wiring cover is fixed to the wet curtain bracket with screws. Its main function is to shield the wiring harness connecting the coupler's B terminal to the water level detection board, thus concealing the wiring harness.

[0122] 25. Water pump mounting bracket: One of the components of the wet curtain bracket assembly, it is fixed to the wet curtain bracket by four screws. At the same time, the water pump is installed on the bracket by buckles and screws. A deep groove is designed inside the mounting bracket for installing the water level detection plate. To prevent the water level detection plate from getting wet, the groove needs to be sealed. The top of the mounting bracket needs to be designed with an annular groove structure for installing waterproof silicone. It is fixed by screws between the wet curtain bracket and the water pump mounting bracket, forcing the silicone to deform, thereby achieving waterproof sealing of the water level detection plate.

[0123] 26. Float mounting bracket: One of the components of the wet curtain bracket assembly. To detect the water level, a movable float is required to work with the water level detection plate to form a detection system. The float mounting bracket is screwed to the water pump mounting bracket and has a movable float embedded inside.

[0124] 27. Water level detection board: One of the components of the wet curtain bracket assembly, installed inside the water pump mounting bracket, connected to the coupler B terminal and the water pump through a sealed wiring harness.

[0125] 28. Waterproof silicone: One of the components of the wet curtain bracket assembly. It is located in the annular groove of the water pump mounting bracket to provide sealing protection for the water level detection plate inside the water pump mounting bracket.

[0126] 29. Air Inlet Grille: A component of the water tank assembly, the air inlet grille has an inner flange at the top that supports and limits the wet curtain bracket. The bottom is a hollow structure that is fixed to the water tank with screws at the four corners. It also serves as the air inlet component of the entire machine.
