[0031] refer to Figures 1 to 5 A sealing structure and a humidifier having the same according to an embodiment of the present invention are described.

[0032] like Figures 1 to 5 As shown, the sealing structure 100 includes a fixed seat 110, which is provided with an opening 111 and a limiting cavity 112, and the limiting cavity 112 is located on one side of the opening 111; a lever 120, the lever 120 includes a fulcrum 122, and a resistance arm 123 and a power arm 124 respectively arranged at opposite ends of the fulcrum 122, the fulcrum 122 is rotatably connected to the fixed seat 110, the resistance arm 123 extends into the limiting cavity 112, the power arm 124 is placed outside the limiting cavity 112, and a sealing plug 121 is provided on the power arm 124, and the sealing plug 121 is used to seal and open the opening 111; a gravity piece 130, the gravity piece 130 is arranged in the limiting cavity 112, the gravity piece 130 is located at the upper end of the resistance arm 123, and the gravity piece 130 is used to apply gravity to the resistance arm 123 to control the rotation of the lever 120.

[0033] like Figures 1 to 3 As shown, the fixed seat 110 has an opening 111 and a limiting cavity 112, the limiting cavity 112 is located on the left side of the opening 111, and the fulcrum 122 of the lever 120 is rotatably set on the fixed seat 110, its resistance arm 123 is located at the left end of the fulcrum 122, and the power arm 124 is located at the right end of the fulcrum 122, wherein the resistance arm 123 extends into the limiting cavity 112, the gravity member 130 is loaded on the resistance arm 123, and the power arm 124 is provided with a sealing plug 121 corresponding to the opening 111, and the rotating axis of the lever 120 is located between the opening 111 and the limiting cavity 112, so that the resistance arm 123 and the power arm 124 can rotate in the same direction above the limiting cavity 112 and the opening 111 respectively. Under normal conditions, the gravity member 130 applies pressure to the resistance arm 123, confining the sealing plug 121 above the opening 111, so that the opening 111 is in an open state. When the fixing seat 110 accidentally tips over, the gravity member 130 moves in the limiting cavity 112 under the action of gravity. As the tipping angle changes, the pressure of the gravity member 130 on the resistance arm 123 gradually decreases, and the power arm 124 starts to rotate and moves the sealing plug 121 toward the opening 111 until the sealing plug 121 completely covers the upper end of the opening 111, so that the opening 111 is in a sealed state. This provides a safety mechanism that can automatically close and seal the opening 111 in the event of tipping or an accident, thereby preventing liquid or other substances from leaking or external objects from entering the interior, thereby protecting the safety of the equipment and the environment.

[0034] Specifically, the gravity piece 130 is a sphere. It should be noted that the shape of the sphere can make the gravity piece 130 more stable when moving in the limiting cavity 112, thereby further providing a greater degree of freedom between the gravity piece 130 and the lever 120. When the lever 120 rotates, the gravity piece 130 can more flexibly adjust its position and change the pressure it applies to the lever 120.

[0035] Specifically, a tubular channel extending in the up and down directions is provided on the fixing seat 110, an opening 111 is provided at the upper end of the tubular channel, and a container is provided at the left end of the tubular channel. The container includes a base 113 and a cover plate 114 matching the base 113, a first buckling portion 115 and a second buckling portion 116 respectively cooperate with the two notch positions on the cover plate 114 for fixation, and the base 113 and the cover plate 114 enclose a limiting cavity 112.

[0036] In some specific embodiments of the present invention, an elastic member 140 is further included. The elastic member 140 is connected to the lever 120 and the fixing seat 110 respectively. The elastic member 140 is used to drive the sealing plug 121 to seal the opening 111.

[0037] like Figure 1 and Figure 2 As shown, the lever 120 is rotatably connected to the fixed seat 110 through a rotating shaft. Specifically, the lever 120 is rotatably set on the base 113. The elastic member 140 is a torsion spring, which is sleeved on the rotating shaft. One of the free ends of the torsion spring is against the base 113, and the other free end is against the sealing plug 121. When the gravity member 130 is loaded on the resistance arm 123, the torsion spring is twisted and deformed, and its elastic potential accumulates. Once the fixed seat 110 tilts, the pressure applied by the gravity member 130 on the lever 120 is reduced, and the external force acting on the torsion spring gradually disappears. The elastic potential energy of the torsion spring will push the torsion spring to restore to its original undeformed state, so as to further drive the lever 120 to rotate, so that the sealing plug 121 on the other end of the lever 120 is tightly covered on the opening 111.

[0038] In some specific embodiments of the present invention, the lever 120 further includes a bending portion 125, and the fulcrum 122 is disposed on the bending portion 125. The bending portion 125 is used to change the extension direction of the resistance arm 123 and the power arm 124. Figure 2 and Figure 3 As shown, the resistance arm 123 and the power arm 124 are respectively arranged at the opposite ends of the bending portion 125. On the one hand, by changing the direction of the two ends of the lever 120, the lever 120 can complete the required rotation while occupying less space. On the other hand, the lever 120 provides additional structural reinforcement to achieve more effective force transmission, thereby increasing the stability of the lever 120 and reducing the possibility of deflection or deformation.

[0039] In some specific embodiments of the present invention, a protrusion 1231 is provided in the middle of the resistance arm 123. The protrusion 1231 is located on the side of the resistance arm 123 close to the gravity member 130. The protrusion 1231 is used to guide the movement of the gravity member 130. Figure 3 and Figure 4 As shown, by providing a protrusion 1231 at the middle upper end of the resistance arm 123, the lever 120 can better adapt to the shape and position of the spherical weight member 130, and achieve uniform pressure distribution on the lever 120 when the spherical weight member 130 applies pressure, avoiding damage or deformation caused by excessive local force, and ensuring that the lever 120 maintains stability and reliability during long-term use.

[0040] In some specific embodiments of the present invention, the cross-sectional area of the limiting cavity 112 gradually increases from bottom to top. It should be noted that the cross-sectional area here refers to the horizontal cross-sectional area of the limiting cavity 112. Specifically, the limiting cavity 112 is in the shape of an inverted cone. It should be noted that the weight member 130 is always arranged in the limiting cavity 112. The inverted cone-shaped limiting cavity 112 can help the weight member 130 to be automatically guided to a suitable position. Specifically, in the process of tilting the fixing seat 110 to straightening it, the conical limiting cavity 112 gradually guides the spherical weight member 130 to the upper end of the resistance arm 123 to ensure that the spherical weight member 130 of the fixing seat 110 can quickly and accurately find the correct position in the limiting cavity 112 and exert pressure on the resistance arm 123, driving the sealing plug 121 to separate from the opening 111.

[0041] In some specific embodiments of the present invention, a sealing gasket 1211 is provided at one end of the sealing plug 121 close to the opening 111, and the sealing gasket 1211 is used to enhance the sealing performance between the sealing plug 121 and the opening 111. Figure 3 and Figure 4 As shown, a through hole is opened on the sealing plug 121, and a snap-fitting boss corresponding to the through hole is provided on the sealing gasket 1211. The snap-fitting boss passes through the through hole and snaps with the sealing plug 121, so that the sealing gasket 1211 is tightly fixed on the sealing plug 121.

[0042] In some specific embodiments of the present invention, a clearance groove 1121 is provided on the wall of the limiting cavity 112. The clearance groove 1121 extends up and down along the wall of the limiting cavity 112. The clearance groove 1121 corresponds to the resistance arm 123. The clearance groove 1121 is used to ensure that the lever 120 can rotate smoothly along the motion trajectory. Specifically, the lever 120 partially penetrates the clearance groove 1121 during the rotation process. As a result, the clearance groove 1121 not only enables the lever 120 to move in the direction defined by the clearance groove 1121, ensuring that the structure maintains the correct position and direction during movement, but also maximizes space, ensuring that the lever 120 can still rotate flexibly in a smaller space.

[0043] like Figures 1 to 5 As shown, a humidifier with a sealing structure 100 includes a water tank 200; a humidifying chamber 210, which is located in the water tank 200 and is used to hold water; an electronic chamber 300, which is arranged at the lower end of the water tank 200 and is connected to the humidifying chamber 210, and is used to hold electronic components; and a sealing structure 100, which is arranged between the humidifying chamber 210 and the electronic chamber 300, and is used to isolate and connect the humidifying chamber 210 and the electronic chamber 300.

[0044] like Figure 5 As shown, the water tank 200 and the electronics compartment 300 are arranged sequentially from top to bottom, with the sealing structure 100 and the humidification compartment 210 disposed within the water tank 200. The electronics compartment 300 and the humidification compartment 210 are connected via an opening 111. When the humidifier is shaken by an accidental collision or movement, the position of the spherical weight 130 changes, and the torsion spring drives the lever 120 upward. Under the elastic action of the torsion spring, the sealing plug 121 is tightly pressed against the opening 111, thereby preventing water from overflowing from the lower water tank 200 into the electronics compartment 300. When the humidifier returns to a stable position, the spherical weight member 130 falls again above the resistance arm 123 under the guidance of the limit cavity 112, and the lever 120 is rotated to make the sealing plug 121 at the other end bounce upward and separate from the opening 111. At this time, the opening 111 returns to the open state and the humidification function operates normally, thereby providing a safety mechanism that can automatically close and seal the opening 111 in the event of tipping or an accident, isolating the humidification chamber 210 and the electronic chamber 300, preventing water from leaking from the humidification chamber 210 into the electronic chamber 300, thereby protecting the safety of electronic components.
