[0041] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0042] The present disclosure provides a humidifier, which includes a humidifying part, a water supply pipeline, and a flexible sealing sleeve. The humidifying part includes a humidifying member and a first connector. Airflow passes through the humidifying member, and the humidifying member increases the humidity of the airflow; the first connector is communicated with the humidifying member and is used for supplying water to the humidifying member.

[0043] The water supply pipeline includes a water tank for storing water and an upper water pipe with one end communicated with the water tank. The other end of the upper water pipe is provided with a second connector having a double-layer structure. The second connector includes an inner connecting pipe and an outer connecting pipe. Among them, the outer connecting pipe surrounds the inner connecting pipe, and the length of the outer connecting pipe is greater than the length of the inner connecting pipe.

[0044] The first end of the flexible sealing sleeve is inserted between the inner connecting pipe and the outer connecting pipe of the second connector, and the second end is sleeved on the outer peripheral side wall of the first connector. The first connector and the outer connecting pipe at least partially overlap in the extending direction of the first connector.

[0045] In the embodiments of the present disclosure, both the first connector and the second connector are in direct contact with the flexible sealing sleeve, which can improve the sealing performance between the contact surfaces and prevent water leakage between the first connector and the second connector. At the same time, the length of the outer connecting pipe of the second connector is greater than that of the inner connecting pipe, so that the outer connecting pipe can provide support for the part of the flexible sealing sleeve sleeved on the first connector, thereby forming a more reliable seal.

[0046] A humidifier is an electrical device used to increase the humidity of air, and some humidifiers also integrate an air purification function.

[0047] Figure 1 FIG. is a schematic structural diagram of a humidifier shown according to an exemplary embodiment. Figure 2 FIG. is a longitudinal sectional view of a humidifier shown according to an exemplary embodiment, as Figure 1 、 Figure 2 shown, the humidifier is sequentially provided with a water filling structure 1 at the top of the humidifier, an air outlet 8 opened on the side of the humidifier, a driver's compartment 9 for providing air outlet power, a humidifying part 3 for humidifying air, and a water tank 2 provided at the bottom from top to bottom.

[0048] The water filling structure 1 includes a funnel-shaped water filling tank 11 and a water tank cover 12 provided in the water filling tank 11. When filling water, the water flows in from between the water filling tank 11 and the water tank cover 12 at the top and flows into the water tank 2 through the water inlet pipe 6 provided in the outer shell 7 of the humidifier. When it is necessary to humidify the air, the water in the water tank 2 is pumped to the humidifying part 3 through the upper water pipe 4 provided in the outer shell 7 to humidify the air. The motor in the driver's compartment 9 drives the fan blades to suck air flow from outside the humidifier. The humidity of the air flow increases after passing through the humidifying part 3 and is discharged from the air outlet 8, realizing the humidification of the air.

[0049] In the embodiments of the present disclosure, "up", "down", "top", and "bottom" are all in accordance with the direction of gravity.

[0050] Figure 3 FIG. is a longitudinal sectional view of a humidifier shown according to an exemplary embodiment from another angle. Figure 4 is Figure 3 an enlarged view of part A in Figure 5 is Figure 3 another enlarged view of part A in a different state in Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 shown, the humidifier includes a humidifying part 3, a water supply pipeline, and a flexible sealing sleeve 42. The humidifying part 3 includes a humidifying member 31 and a first connector 32. The air flow passes through the humidifying member 31, and the humidifying member 31 increases the humidity of the air flow; the first connector 32 is communicated with the humidifying member 31 and is used to supply water to the humidifying member 31.

[0051] The water supply pipeline includes a water tank 2 for storing water and a water supply pipe 4 with one end communicating with the water tank 2. The other end of the water supply pipe 4 is provided with a second connector 41 having a double-layer structure. The second connector 41 includes an inner connecting pipe 411 and an outer connecting pipe 412. Among them, the outer connecting pipe 412 is arranged around the inner connecting pipe 411, and the length of the outer connecting pipe 412 is greater than that of the inner connecting pipe 411.

[0052] The first end 421 of the flexible sealing sleeve 42 is inserted between the inner connecting pipe 411 and the outer connecting pipe 412 of the second connector 41, and the second end 422 is sleeved on the outer peripheral side wall of the first connector 32. The first connector 32 and the outer connecting pipe 412 at least partially overlap in the extending direction of the first connector 32.

[0053] In the embodiments of the present disclosure, the first connector 32 and the second connector 41 are connected by the flexible sealing sleeve 42 arranged between them. The first connector 32 and the second connector 41 are both in direct contact with the flexible sealing sleeve 42, which is beneficial to improving the sealing performance of the contact surface. Moreover, by setting the length of the outer connecting pipe 412 of the second connector 41 to be greater than that of the inner connecting pipe 411, the outer connecting pipe 412 can provide support for the part of the flexible sealing sleeve 42 sleeved on the first connector 32, making the flexible sealing sleeve 42 contact the first connector 32 more closely, improving the sealing effect, and avoiding water leakage between the first connector 32 and the second connector 41.

[0054] In some embodiments, the flexible sealing sleeve 42 has elasticity and can be made of an elastic material, such as silicone, rubber, etc. The flexible sealing sleeve 42 is in interference fit with the inner connecting pipe 411 and the outer connecting pipe 412, and a more compact base is obtained through the elasticity of the flexible sealing sleeve 42 itself after extrusion, improving the sealing effect.

[0055] In some embodiments, as Figure 4 、 Figure 5 shown, a first buffer rib 423 is arranged on the inner peripheral side wall of the flexible sealing sleeve 42. The first buffer rib 423 is arranged between the inner connecting pipe 411 and the first connector 32, and the first buffer rib 423 abuts against the pipe orifice of the inner connecting pipe 411.

[0056] In the embodiments of the present disclosure, by arranging the first buffer rib 423 on the inner peripheral side wall of the flexible sealing sleeve 42, the situation that the first connector 32 and the second connector 41 directly collide during installation is avoided, protecting the integrity of the first connector 32 and the second connector 41.

[0057] In some embodiments, as Figure 4 、 Figure 5 shown, the humidifier further includes a mounting bracket 5 sleeved on the outer peripheral side wall of the second connector 41.

[0058] A limiting rib 51 is provided on the inner side of the mounting bracket 5. The limiting rib 51 is arranged at an interval from the pipe orifice of the outer connecting pipe 412. A second buffer rib 424 is provided on the outer peripheral side wall of the second end 422 of the flexible sealing sleeve 42. The second buffer rib 424 is located between the limiting rib 51 and the pipe orifice of the outer connecting pipe 412.

[0059] In the embodiment of the present disclosure, when assembling the mounting bracket 5, the flexible sealing sleeve 42 and the second connector 41, it is necessary to first insert the first end 421 of the flexible sealing sleeve 42 between the inner connecting pipe 411 and the outer connecting pipe 412, and then insert the second connector 41 and the flexible sealing sleeve 42 together into the mounting bracket 5. The limiting rib 51 of the mounting bracket 5 is used to stop the installation actions of the second connector 41 and the flexible sealing sleeve 42, so as to prevent the second connector 41 and the flexible sealing sleeve 42 from being over-installed. Providing the second buffer rib 424 on the second end 422 of the flexible sealing sleeve 42 can play a buffering role when the second connector 41 and the flexible sealing sleeve 42 are installed in place or over-installed, and avoid damage to the mounting bracket 5 of the second connector 41.

[0060] The mounting bracket 5 is used to fix the second connector 41 and is generally fixed to the housing 7 of the humidifier. Of course, the mounting bracket 5 can also be fixed to other structures of the humidifier.

[0061] In some embodiments, such as Figure 4 、 Figure 5 shown, the thickness of the peripheral side wall of the first end 421 of the flexible sealing sleeve 42 is set to shrink.

[0062] In the embodiment of the present disclosure, setting the thickness of the peripheral side wall of the first end 421 of the flexible sealing sleeve 42 to shrink is beneficial to inserting the flexible sealing sleeve 42 between the inner connecting pipe 411 and the outer connecting pipe 412. Especially when the flexible sealing sleeve 42 has elasticity, the installation difficulty can be greatly reduced.

[0063] In some embodiments, after the thickness of the peripheral side wall of the first end 421 of the flexible sealing sleeve 42 shrinks, it is arranged at an interval from the inner connecting pipe 411.

[0064] In some embodiments, after the thickness of the peripheral side wall of the first end 421 of the flexible sealing sleeve 42 shrinks, it is arranged at an interval from the outer connecting pipe 412.

[0065] In some embodiments, such as Figure 4 、 Figure 5 shown, a plurality of sealing ribs 425 are provided on the inner peripheral side wall of the second end 422 of the flexible sealing sleeve 42. The plurality of sealing ribs 425 are in contact with the outer peripheral side wall of the first connector 32 to form a sealing effect.

[0066] In an embodiment of the present disclosure, the pressure between the sealing rib 425 and the outer peripheral side wall of the first connector 32 is greater, and the resulting sealing effect is also better, thereby avoiding water leakage between the first connector 32 and the flexible sealing sleeve 42.

[0067] In some embodiments, the sealing rib 425 has a certain height. As Figure 5 shown, when the first connector 32 and the flexible sealing sleeve 42 are not yet assembled, the sealing rib 425 maintains its original posture. As Figure 4 shown, after the first connector 32 and the flexible sealing sleeve 42 are assembled, the sealing rib 425 is squeezed by the first connector 32. Figure 4 、 Figure 5 exemplarily shows that the number of sealing ribs 425 of the flexible sealing sleeve 42 is two, but it can also be set to other numbers, such as one, three, etc.

[0068] In some embodiments, the first connector 32 is gradually tapered towards its pipe orifice to facilitate insertion into the flexible sealing sleeve 42.

[0069] In some embodiments, as Figure 4 、 Figure 5 shown, the humidifying part 3 further includes a water immersion pipe 33 connected to the humidifying member 31. The first connector 32 is in communication with the water immersion pipe 33. The water immersion pipe 33 is adhered to the humidifying member 31. A local part of the pipe wall where the water immersion pipe 33 is adhered to the humidifying member 31 is recessed towards the inside of the water immersion pipe 33 to form a recessed part 331. The recessed part 331 is provided with a water immersion hole 332 that communicates the inside of the water immersion pipe 33 with the humidifying member 31.

[0070] Water enters the water immersion pipe 33 through the first connector 32 and flows into the humidifying member 31 from the water immersion hole 332 of the water immersion pipe 33 to supply water to the humidifying member 31.

[0071] In an embodiment of the present disclosure, by providing the water immersion hole 332 in the recessed part 331 of the water immersion pipe 33, it is possible to prevent the colloid for adhering the water immersion pipe 33 and the humidifying member 31 from blocking the water immersion hole 332 and keep the water immersion hole 332 unobstructed.

[0072] The colloid for adhering the water immersion pipe 33 and the humidifying member 31 can be a liquid glue, a solid glue, or a glue in other forms. The present disclosure does not limit this.

[0073] In some embodiments, as Figure 4 、 Figure 5 shown, the edge of the water immersion hole 332 extends towards the humidifying member 31 to guide the water in the water immersion pipe 33 to flow towards the humidifying member 31.

[0074] In an embodiment of the present disclosure, by extending the edge of the water immersion hole 332 towards the humidifying member 31, the water in the water immersion pipe 33 can be guided to flow towards the humidifying member 31. When there is sufficient water in the water immersion pipe 33, the flow rate can be increased. When there is less water in the water immersion pipe 33, water stagnation in the water immersion pipe 33 can be avoided, and as much water as possible can be introduced into the humidifying member 31.

[0075] Figure 6 It is a longitudinal sectional view of another angle of a humidifier shown according to an exemplary embodiment. Figure 7 It is Figure 6 The enlarged view of part B in Figure 6 、 Figure 7 As shown, the humidifier further includes a water filling structure 1, and the water filling structure 1 includes a water filling tank 11 and a water tank cover 12.

[0076] The water filling tank 11 is arranged to shrink from one end to the other end, forming a hollow funnel-shaped structure. The shrinking end of the water filling tank 11 extends to form a circumferentially closed extension portion 111.

[0077] The water tank cover 12 is arranged in the water filling tank 11. The water tank cover 12 includes a tank cover base 121 and a cover body 122. The tank cover base 121 is connected to the extension portion 111 of the water filling tank 11 to form a water storage tank 112. A water discharge hole 114 is provided on the bottom wall of the water storage tank 112 along the direction of gravity. The cover body 122 is connected to the tank cover base 121, and the edge of the cover body 122 extends towards the inner circumferential side wall of the water filling tank 11 and is spaced from the inner circumferential side wall of the water filling tank 11.

[0078] The extension portion 111 of the water filling tank 11 is provided with a water guiding eaves 113 extending towards the tank cover base 121 along the circumferential direction. The water guiding eaves 113 is arranged at the notch of the water storage tank 112 and is spaced from the tank cover base 121 to form a water leakage groove for water circulation.

[0079] The water supply pipeline includes a water inlet pipe 6. One end of the water inlet pipe 6 is communicated with the water discharge hole 114, and the other end is communicated with the water tank 2.

[0080] In an embodiment of the present disclosure, a water guiding eaves 113 is arranged at the notch of the water storage tank 112 to narrow the notch of the water storage tank 112 and prevent foreign objects from entering the water storage tank 112 along with the water flow.

[0081] Figure 8 It is a longitudinal sectional view of another angle of a humidifier shown according to an exemplary embodiment.

The first pipe section 611 is provided with a flat portion 612 and a circular pipe orifice for communicating with the water inlet pipe 6. The diameter of the second pipe section 614 in the vertical direction is smaller than that in the horizontal direction. The first pipe section 611 and the second pipe section 614 are fixedly connected, and the extending directions of the first pipe section 611 and the second pipe section 614 are arranged crosswise.

[0082] In an embodiment of the present disclosure, by providing the flat portion 612 on the first pipe section 611 of the water tank docking member 61, the narrow space on the side wall of the humidifier can be effectively utilized, which neither occupies more space to change the shape of the humidifier nor reduces the water flow velocity.

[0083] Figure 11 It is a schematic structural diagram of a water tank docking member shown according to an exemplary embodiment. As Figure 9 、 Figure 10 、 Figure 11 shown, fixing ears 613 are provided on the outer peripheral side wall of the flat portion 612 of the first pipe section 611 of the water tank docking member 61. The extending direction of the fixing ears 613 is the same as that of the first pipe section 611, and the fixing ears 613 are provided on the side wall of the flat portion 612 with a larger diameter.

[0084] In an embodiment of the present disclosure, by providing the fixing ears 613 on the first pipe section 611, it is convenient to fix the water tank docking member 61 to the housing 7 of the humidifier or other structures through the fixing ears 613. The fixing method can be various, such as fixing with screws.

[0085] Figure 11 It is exemplarily shown in [reference] that the number of the fixing ears 613 is two, but the fixing ears 613 can also be set to other numbers, such as one, three, etc.

[0086] In some embodiments, as Figure 11 shown, an annular protrusion is circumferentially provided on the outer peripheral side wall of the circular pipe orifice of the first pipe section 611. The circular pipe orifice of the first pipe section 611 is inserted into the water inlet pipe 6 to form a plug connection with the water inlet pipe 6, and the annular protrusion is used to strengthen the connection strength between the circular pipe orifice of the water tank docking member 61 and the water inlet pipe 6.

[0087] Figure 11 It is exemplarily shown in [reference] that the number of the annular protrusions is two, but the annular protrusions can also be set to other numbers, such as one, three, etc.

[0088] In some embodiments, as Figure 9 、 Figure 10 、 Figure 11As shown, a groove is circumferentially formed on the outer peripheral side wall of the second pipe section 614, and a flexible sealing ring is arranged in the groove. The second pipe section 614 is inserted into the water inlet 21 of the water tank 2, and a good sealing effect is obtained under the action of the flexible sealing ring. Among them, Figure 9 FIG. Figure 9 shows a schematic diagram of the second pipe section 614 and the water inlet 21 of the water tank 2 in an assembled state. Figure 10 FIG. Figure 10 shows a schematic diagram of the second pipe section 614 and the water inlet 21 of the water tank 2 in a non-assembled state.

[0089] In some embodiments, the flexible sealing ring is made of a flexible material, such as rubber or silica gel.

[0090] In some embodiments, the pipe orifice of the second pipe section 614 is constricted to facilitate insertion into the water inlet 21 of the water tank 2. The constriction of the pipe orifice of the second pipe section 614 can be achieved in various ways, such as chamfering the pipe orifice of the second pipe section 614.
