At this time, the float structure is relatively rotated, and the second plug-in 4 is loosened so that the second plug-in 4 can be rotated and connected with the other side of the base 8, thereby completing the installation of the first plug-in 3 and the second plug-in 4 with the base 8; when it is necessary to remove the float structure from the base 8, push the driving block 5 so that the relative positions of the first plug-in 3 and the second plug-in 4 are close, so that the first plug-in 3 and the second plug-in 4 can be separated from the base 8; and the first plug-in 3 and the second plug-in 4 will not be separated from the accommodating cavity, the operation process is simple and convenient, and the float structure and the base 8 can be quickly installed and disassembled, and the relative wear of the float structure and the base 8 will not be caused during the installation and disassembly process, thereby effectively improving the service life of the float structure and the base 8, and ensuring the normal operation of the humidifier.

[0046] Specifically, the first direction is Figure 1 Arrow indicates direction.

[0047] Alternatively, see Figure 3 The outer diameter of the second plug-in 4 is greater than the outer diameter of the first plug-in 3 , and the second plug-in 4 is sleeved on the outside of the first plug-in 3 , and the axial direction of the first plug-in 3 is the same as the axial direction of the second plug-in 4 .

[0048] As an alternative, see Figure 6 The outer diameter of the second plug-in 4 is greater than the outer diameter of the first plug-in 3 . Along the first direction, the first plug-in 3 and the second plug-in 4 are spaced apart from the float lever 2 , and the second plug-in 4 can be sleeved on the outside of the first plug-in 3 or away from the first plug-in 3 .

[0049] Optionally, the first plug-in 3 and the second plug-in 4 are both slidably disposed in the accommodating cavity of the float lever 2 .

[0050] As an alternative, one of the first plug-in 3 and the second plug-in 4 is fixedly connected to the float lever 2, and the other of the first plug-in 3 and the second plug-in 4 is slidably disposed on the float lever 2. Optionally, the first plug-in 3 is fixedly connected to the float lever 2, the second plug-in 4 is slidably disposed on the float lever 2, the second plug-in 4 can approach or move away from the first plug-in 3, and the second plug-in 4 has a driving block 5.

[0051] Preferably, the second plug-in unit 4 has a driving block 5. Along the axis direction of the second plug-in unit 4, the driving block 5 can drive the second plug-in unit 4 to move in a direction close to the first plug-in unit 3.

[0052] As an alternative, the first plug-in unit 3 has a driving block 5. Along the axis direction of the first plug-in unit 3, the driving block 5 can drive the first plug-in unit 3 to move in a direction close to the second plug-in unit 4.

[0053] As an alternative, both the first plug-in unit 3 and the second plug-in unit 4 have a drive block 5 .

[0054] See also Figure 3 Furthermore, the float structure further includes a first elastic member 6, which is configured to always have a tendency to drive the first plug-in 3 and the second plug-in 4 to move away from each other. When the driving block 5 is pushed to bring the first plug-in 3 and the second plug-in 4 closer together, the first elastic member 6 can apply a force to move the first plug-in 3 and the second plug-in 4 away from each other, thereby ensuring that the first plug-in 3 and the second plug-in 4 can return to their original positions, thereby enabling the normal operation of the float structure.

[0055] Optionally, the first elastic member 6 is a compression spring, and the two ends of the compression spring are respectively in contact with the first plug-in 3 and the second plug-in 4. In this way, the first plug-in 3 and the second plug-in 4 are always subjected to a force moving away from each other, so that the first plug-in 3 and the second plug-in 4 are in contact with the float lever 2, so that the float structure is connected to the rotation of the base 8.

[0056] It should be noted that see Figure 3The first plug-in 3 includes a first barrel portion 31 located in the accommodating cavity and a first rod portion 32 penetrating the first through hole 21, and the outer diameter of the first barrel portion 31 is larger than the outer diameter of the first through hole 21; the second plug-in 4 includes a second barrel portion 41 located in the accommodating cavity and a second rod portion 42 penetrating the second through hole 22, and the outer diameter of the second barrel portion 41 is larger than the outer diameter of the second through hole 22. Such an arrangement can effectively prevent the first plug-in 3 and the second plug-in 4 from being separated from the float lever 2 from the first through hole 21 and the second through hole 22, so as to ensure the structural integrity of the float structure.

[0057] Optionally, the inner diameter of the second barrel portion 41 is greater than the outer diameter of the first barrel portion 31 , so that the second barrel portion 41 can be sleeved on the first barrel portion 31 .

The first plug-in 3 and the second plug-in 4 can be installed or removed from the float lever 2 through the countersunk hole 24, and the cover plate 7 can open or close the countersunk hole 24. When the first plug-in 3 and the second plug-in 4 are damaged, the cover plate 7 is opened, the first plug-in 3 and the second plug-in 4 are taken out, and the first plug-in 3 and the second plug-in 4 are replaced, thereby reducing the maintenance and replacement cost of the float structure; the cover plate 7 is used to close the countersunk hole 24, which can effectively prevent foreign impurities from entering the accommodating cavity of the float lever 2, which can not only prevent the first plug-in 3 and the second plug-in 4 from being damaged by the impurities, but also ensure the smoothness of the relative movement of the first plug-in 3 and the second plug-in 4.

[0061] Optionally, the cover plate 7 is connected to the float lever 2 via a connecting piece. Preferably, the connecting piece is a bolt, which passes through the cover plate 7 and is threadedly connected to the float lever 2.

[0062] See also Figure 1 , Figure 2 and Figure 4 The float lever 2 also has a protrusion 25, which can contact or separate from the valve body to open or close the valve body. By rotating the float lever 2 relative to the base 8, the protrusion 25 can contact or separate from the valve body, thereby opening or closing the valve body, so that the water in the water tank enters or stops entering the base 8.

[0063] Optionally, the float body 1 and the float lever 2 are integrally formed. The molding process of the float body 1 and the float lever 2 can effectively reduce the number of parts, and the molding process has high production efficiency, simple operation and low production cost.

The second elastic member 44 abuts against the first plug-in 3, and the second elastic member 44 is configured to always have a tendency to drive the first plug-in shaft 43 to move in a direction away from the first plug-in 3.

[0072] By pressing the first plug shaft 43 or pushing the driving block 5, the first plug shaft 43 can be moved in a direction close to the first plug-in 3. At this time, the second elastic member 44 is compressed and applies an opposite force to the first plug shaft 43. When the first plug shaft 43 is rotationally connected to the base 8, the second plug-in 4 returns to its original position under the force of the second elastic member 44.

[0077] Optionally, a protrusion 51 is provided on the driving block 5, and two grooves 26 are provided on the float lever 2 along the first direction. When the second plug-in 4 needs to be inserted into the base 8, the protrusion 51 is inserted into the groove 26 on the float lever 2 close to the first plug-in 3, so that the second plug-in 4 is retracted into the accommodating cavity; when the second plug-in 4 completes the rotation connection with the base 8, the protrusion 51 is inserted into the groove 26 on the float lever 2 close to the second plug-in 4, so that the second plug-in 4 is inserted into the base 8.
