DETAILED DESCRIPTION

[0045] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0046] like Figure 1-10As shown, a humidifier 100 according to an embodiment of the present invention includes a base 1, a water tank 2, and an adjustment component 3. The upper end of the base 1 is connected to the lower end of the water tank 2. An annular groove 11 is formed on one of the upper end surface of the base 1 and the lower end surface of the water tank 2. A sealing ring 4 is disposed within the annular groove 11. A perforation 13 is formed on the peripheral wall of the annular groove 11, which communicates with the annular groove 11.

[0047] like Figure 6 and Figure 8 As shown, the adjustment member 3 fits into the through-hole 13. The adjustment member 3 has a first end and a second end. The first end of the adjustment member 3 extends through the through-hole 13 into the annular groove 11 to push the sealing ring 4 away from the annular groove 11, so that the sealing ring 4 abuts against the other of the upper end surface of the base 1 and the lower end surface of the water tank 2.

[0048] In the humidifier of the embodiment of the present invention, when the first end of the adjusting component 3 passes through the through hole 13 and extends into the annular groove 11, the sealing ring 4 can be lifted up to make the sealing ring 4 abut against the other of the upper end surface of the base 1 and the lower end surface of the water tank 2, thereby improving the sealing between the water tank 2 and the base 1, improving the safety of the humidifier 100 during use, and improving the user experience during use. Moreover, the operating principle is simple and easy to implement.

[0049] In some specific embodiments, such as Figure 1 As shown, the annular groove 11 is provided on the upper end surface of the base 1 as an example. The upper end surface of the base 1 is provided with an annular groove 11, which is formed by a downward depression of the upper end surface of the base 1. The first end of the adjustment component 3 extends through the through-hole 13 into the annular groove 11, thereby lifting the sealing ring upward and contacting the lower end surface of the water tank 2, thereby improving the sealing between the water tank 2 and the base 1.

[0050] Optionally, the through-hole 13 penetrates the peripheral wall of the annular groove 11 in the thickness direction thereof, and the adjusting member 3 is adjustable in the axial position of the through-hole 13. Specifically, by adjusting the adjusting member 3 in the axial position of the through-hole 13, the adjusting member 3 can lift the sealing ring 4 to abut against the other of the upper end surface of the base 1 and the lower end surface of the water tank 2, and the operation is simple.

[0051] Alternatively, as Figure 3 As shown, the peripheral wall of the annular groove 11 is further provided with a slot 12, which is in communication with a through-hole 13. A lug 21 is provided on the other of the upper end of the base 1 and the lower end of the water tank 2. The lug 21 has a lug hole 211. The lug 21 is inserted into the slot 12, and the first end of the adjustment member 3 can pass through the through-hole 13 and the lug hole 211.

[0052] Specifically, when the slot 12 is located on the outer peripheral wall of the annular groove 11 , the slot 12 is located outside the through-hole 13 and is connected to the through-hole 13 , and the first end of the adjustment component 3 passes through the slot 12 and the through-hole 13 and extends into the annular groove 11 .

[0053] When the slot 12 is located on the inner wall of the annular groove 11 , the slot 12 and the through hole 13 are arranged corresponding to the annular groove 11 . The first end of the adjustment component 3 passes through the through hole 13 and extends into the annular groove 11 to lift the sealing ring 4 and then passes through the slot 12 .

[0054] The lug 21 is inserted into the slot 12, which improves the fit between the base 1 and the water tank 2. The first end of the adjustment component 3 passes through the lug 21 and the annular groove 11, realizing the connection between the water tank 2 and the base 1, improving the firmness of the connection between the water tank 2 and the base 1, and the connection method is simple.

[0055] In some specific embodiments, Figure 8 As shown, the lower end of the water tank 2 is provided with a lug 21, and a lug hole 211 passes through the lug 21 along the thickness direction of the lug 21. The lug 21 extends downward from the lower end surface of the water tank 2 to be inserted into the slot 12 so that the lug hole 211 is connected to the through hole 13.

[0056] Optionally, there are at least two lugs 21, which are spaced apart circumferentially around the other of the upper end of the base and the lower end of the water tank 2. There are at least two slots 12, which are spaced apart circumferentially around the peripheral wall of the annular groove 11, and the at least two slots 12 correspond one-to-one to the at least two lugs 21.

[0057] Specifically, at least two lugs 21 are arranged circumferentially at intervals around the lower end of the water tank 2. The provision of at least two lugs 21 and at least two slots 12 improves the connection between the water tank 2 and the base 1, further ensuring the firmness and sealing of the connection between the water tank 2 and the base 1.

[0058] Alternatively, as Figure 1-6 As shown, a boss 5 is provided on the outer side of the peripheral wall of the annular groove 11. The boss 5 has a mounting hole 51 formed therein. The mounting hole 51 communicates with the slot 12 and the through-hole 13, with the central axis of the mounting hole 51 being collinear with the central axis of the through-hole 13. The first end of the adjustment component 3 can pass through the mounting hole 51, the lug hole 211, and the through-hole 13. The provision of the boss 5 further improves the fit between the base 1 and the water tank 2, providing a more secure connection between the water tank 2 and the base 1.

[0059] Optionally, the boss 5 is arranged on the outside of the outer peripheral wall of the annular groove 11, and the upper end surface of the boss 5 is higher than the upper end surface of the base 1. When the lug 21 is inserted into the slot 12, the upper end of the boss 5 can limit the lug 21 to ensure that the lug 21 is firmly installed in the slot 12.

[0060] Alternatively, as Figure 6 As shown, the end of the boss 5 away from the slot 12 has a mating hole 52, which extends axially along the mounting hole 51 and is in communication with the mounting hole 51. The inner circumferential surface of the mating hole 52 has an internal thread, and the second end of the adjustment component 3 has an external thread, which is threadedly engaged in the mating hole 52.

[0061] Specifically, the second end of the adjustment component 3 is threadedly engaged with the mating hole 52, providing a simple and easy-to-operate engagement. When the second end of the adjustment component 3 is screwed in or out of the mating hole 52 along the axial direction of the mating hole 52, it drives the first end of the adjustment component 3 to move axially along the mounting hole 51. The movement of the first end of the adjustment component 3 is simple, and the threaded engagement of the second end of the adjustment component 3 with the mating hole 52 also ensures the stability of the first end of the adjustment component 3.

[0062] Specifically, if Figure 6 As shown, the mounting hole 51 is located on the bottom surface of the matching hole 52, the central axis of the mounting hole 51 is collinear with the central axis of the matching hole 52, and the cross-sectional area of ​​the matching hole 52 is larger than the cross-sectional area of ​​the mounting hole 51, so that the second end of the adjustment component 3 is not easy to enter the mounting hole 51.

[0063] Alternatively, as Figure 4 and Figure 8 As shown, the adjustment component 3 includes an adjustment rod 31 and an adjustment head 32. One end of the adjustment rod 31 passes through the lug hole 211 and the through hole 13 and extends into the annular groove 11. The other end of the adjustment rod 31 is connected to the adjustment head 32. The outer peripheral surface of the adjustment head 32 has an external thread, and the adjustment head 32 is threadedly engaged in the mating hole 52.

[0064] Specifically, one end of the adjustment rod 31 forms the first end of the adjustment component 3, and the adjustment head 32 forms the second end of the adjustment component 3. The cross-sectional area of ​​the adjustment head 32 is larger than the cross-sectional area of ​​the other end of the adjustment rod 31. The adjustment rod 31 fits within the mounting hole 51, and the adjustment head 32 is threadedly engaged within the mating hole 52. By rotating the adjustment head 32 to move along the axial direction of the mating hole 52 within the mating hole 52, the adjustment rod 31 is driven to move along the axial direction of the mating hole 52. This operation is simple, and the structure of the adjustment component 3 is simple, saving manufacturing costs.

[0065] Alternatively, as Figure 4 and Figure 8 As shown, the adjustment component 3 also includes a rod head 33, which is arranged at the other end of the adjustment rod 31. The end of the adjustment head 32 close to the adjustment rod 31 has a connecting groove 321, and the rod head 33 and the other end of the adjustment rod 31 are movably fitted in the connecting groove 321.

[0066] Specifically, the adjustment rod 31 is connected to the adjustment head 32 by the engagement of the rod head 33 with the connecting groove 321, resulting in a simple connection. The rod head 33 flexibly engages within the connecting groove 321. When the adjustment head 32 is rotated, the rod head 33 does not rotate with the adjustment head 32, thereby ensuring that the adjustment rod 31 does not rotate with the adjustment head 32, thereby reducing friction between the adjustment rod 31 and the inner circumference of the lug hole 211 and the inner circumference of the through hole 13.

[0067] Alternatively, as Figure 8 As shown, the connecting groove 321 includes a first groove section 3211 and a second groove section 3212, with the second groove section 3212 being located outside the first groove section 3211. The cross-sectional area of ​​the other end of the adjustment rod 31 is smaller than the cross-sectional area of ​​the rod head 33. The inner circumference of the first groove section 3211 matches the outer circumference of the other end of the adjustment rod 31, and the inner circumference of the second groove section 3212 matches the outer circumference of the rod head 33.

[0068] Specifically, the cross-sectional area of ​​the second slot section 3212 is larger than the cross-sectional area of ​​the first slot section 3211, the rod head 33 is arranged in the second slot section 3212 and is adapted to the second slot section 3212, and the other end of the adjusting rod 31 is arranged in the first slot section 3211 and is adapted to the first slot section 3211. The first slot section 3211 can limit the rod head 33, ensuring that the rod head 33 is firmly installed in the second slot section 3212, thereby ensuring that the adjusting rod 31 is firmly connected to the adjusting head 32 through the rod head 33.

[0069] Alternatively, as Figure 8 As shown, the adjustment component 3 also includes a knob 34, which is arranged at the end of the adjustment head 32 away from the adjustment rod 31, so that the user can move the adjustment head 32 in the matching hole 52 by rotating the knob 34. The cross-sectional area of ​​the knob 34 is larger than the cross-sectional area of ​​the matching hole 52, so that the knob 34 is always located outside the matching hole 52, which is convenient for operation.

[0070] Alternatively, as Figure 6 and Figure 8 As shown, the inner circumference of the through hole 13 is truncated cone-shaped, and the cross-sectional area of ​​the through hole 13 gradually decreases along the direction in which the first end of the adjustment component 3 penetrates the through hole 13 . The outer circumference of the first section of the adjustment component 3 is truncated cone-shaped and matches the through hole 13 .

[0071] Specifically, the cross-sectional area of ​​the end of the through hole 13 away from the slot 12 is smaller than the cross-sectional area of ​​the end of the through hole 13 adjacent to the slot 12, one end of the adjustment rod 31 is frustum-shaped and adapted to the through hole 13, and the cross-sectional area of ​​one end of the adjustment rod 31 is smaller than the cross-sectional area of ​​the end of the through hole 13 away from the slot 12.

[0072] Specifically, when the adjustment rod 31 passes through the through hole 13 , the through hole 13 can guide one end of the adjustment rod 31 , making it easier for one end of the adjustment rod 31 to pass through the through hole 13 , thereby reducing collision with the inner circumference of the through hole 13 .

[0073] Alternatively, as Figure 2 and Figure 9 As shown, the humidifier 100 also includes a bracket 6, which is arranged in the annular groove 11, and the sealing ring 4 is arranged on the bracket 6. The first end of the adjustment component 3 extends into the annular groove 11 and contacts the bottom surface of the bracket 6 to push the bracket 6 away from the annular groove 11, so that the sealing ring 4 abuts against the other of the upper end surface of the base 1 and the lower end surface of the water tank 2.

[0074] Specifically, the sealing ring 4 is arranged on the bracket 6, and one end of the adjusting rod 31 pushes the bracket 6 upward to make the sealing ring 4 abut against the bottom surface of the water tank 2, avoiding direct contact between one end of the adjusting rod 31 and the sealing ring 4, so as to reduce the squeezing of the sealing ring 4 by one end of the adjusting rod 31, so that the sealing ring 4 is squeezed between the bracket 6 and the bottom surface of the water tank 2, thereby ensuring the sealing effect of the sealing ring 4.

[0075] Specifically. Figure 9 As shown, the top surface of the bracket 6 has a locking position 61 , and the lower end of the sealing ring 4 is locked in the locking position 61 so that the sealing ring 4 is firmly installed on the bracket 6 .

[0076] Alternatively, as Figure 9 As shown, the bottom surface of the bracket 6 is an inclined surface extending along the direction in which the first end of the adjusting component 3 passes through the through hole 13 and slants downward.

[0077] Specifically, the bottom surface of the bracket 6 is an inclined surface extending from the outer side of the bracket 6 to the inner side of the bracket 6 and tilted downward. When one end of the adjusting rod 31 extends into the annular groove 11, the inclined surface can guide one end of the adjusting rod 31, so that one end of the adjusting rod 31 can easily push the bracket 6 upward to ensure the sealing effect.

[0078] Alternatively, as Figure 10 As shown, in some other embodiments, a limiting portion 14 is provided on the inner wall surface of the second end of the annular groove 11 adjacent to the adjusting component 3, and the limiting portion 14 extends from the inner wall surface of the second end of the annular groove 11 adjacent to the adjusting component 3 to the inner wall surface of the second end of the annular groove 11 away from the adjusting component 3, so as to limit the axial movement of the bracket 6 in the annular groove 11, thereby ensuring that the bracket 6 is firmly installed in the annular groove 11 and is not easily detached from the annular groove 11.
