[0018] The technical solutions in the embodiments of the present application will be clearly and completely described in combination with the drawings in the embodiments of the present application.

[0019] As Figures 1 to 2As shown, the humidifier of the utility model includes humidifier base 100, upper cover assembly 200. Upper cover assembly 200 is covered on humidifier base 100, and humidifier base 100 has atomizing device 110, water tank 120 and heat shield 130. The inside of heat shield 130 is used as atomizing space, and atomizing device 110 is arranged in the atomizing space. The water body is heated by heating body to generate mist. Upper cover assembly 200 is provided with mist outlet 210. Mist outlet 210 is communicated with the atomizing space of humidifier base 100 to form mist outlet channel. Mist outlet 210 is provided with valve core 220 that can slide up and down. The upper part of valve core 220 is provided with sealing valve 230 that is used to press down and block mist outlet 210. Sealing valve 230 can be made of rubber, nylon, polytetrafluoroethylene or metal to provide good sealing property and wear resistance.

[0020] The lower part of valve core 220 is provided with fixed support 140 and plummet 150. Fixed support 140 is located in the mist outlet channel and is provided with opening for the mist to pass through. Plunger 150 includes rod body 151 at the upper end, rotating part 152 at the middle segment and counterweight part 153 at the lower end, and the three are integrally formed. Rotating part 152 is rotatably and movably arranged on fixed support 140. Rotating part 152 can be in the form of a ball or other rotatable shapes, such as an ellipsoid. Counterweight part 153 at the lower end is used as gravity part, and a certain distance is formed between the rotating part 152 to form a force arm. Counterweight part 153 can be in any shape and has sufficient weight. When the humidifier is in the upright state, the upper end 151 is driven to rotate to the top of the bottom surface of valve core 220 under the action of gravity, and when the humidifier is in the tilted state, the upper end 151 is driven to rotate a certain distance or to the bottom surface of valve core 220 to make the valve body 230 fall to block.

[0021] When the machine is normally placed and works, plummet 150 is in the vertical state under the action of gravity of counterweight part 153. The upper end abuts against the bottom of valve core 220 to make valve body 230 open to form steam outlet gap 231, and the mist can be normally discharged. When the machine is tilted, counterweight part 153 of plummet 150 falls downward, the upper end is away from the bottom of valve core 220, valve core 220 moves downward, valve body 230 is closed, steam outlet gap 231 disappears, and the water cannot leak out of the machine.

[0022] In the above scheme, the lower end surface of valve core 220 is preferably a lower convex arc surface, especially a spherical surface, which can reduce friction resistance and promote the rapid falling of the valve body. Rotating part 152 is in the form of a ball or other rotatable shapes, such as an ellipsoid.

[0023] As an improved scheme, an elastic body, such as spring 240, can be further arranged on valve core 220. The two ends of spring 240 abut against the rigid bottom of upper cover assembly and the lower part of valve core respectively. Spring 240 is used to drive valve core 220 to slide downward by the elasticity of spring 240, so that the valve body of valve core not only relies on the gravity of itself, but also relies on the additional elastic force to achieve rapid movement and strong blocking.

[0024] As an improved solution, the counterweight member 153 is suspended in the upper portion of the interior space of the humidifier as a shock absorber, which can enhance the anti-toppling capability of the humidifier.

[0025] As an improved solution, the upper cover assembly 200 is arranged above the water tank 120, and a sealing ring 250 is arranged at the joint between the upper cover assembly 200 and the water tank 120, which can solve the problem of water leakage from the joint between the upper cover and the water tank during toppling.

[0026] As an improved solution, the upper cover assembly 200 has a top cover and a bottom shell, the mist outlet 210 is arranged on the bottom shell of the upper cover assembly 200, and the top cover of the upper cover assembly 200 is provided with a steam outlet hole 260 which is communicated with the mist outlet 210 via a cavity. The top cover and the bottom shell are combined to form the cavity, which serves as a protection for the sealing valve 230.

[0027] In the utility model, according to the requirement of the product, the installation of the plummet 150 has two modes: as shown in Figure 3 , the fixed support 140 is arranged on the heat shield 130 in the humidifier base 100, or as shown in Figure 4 , the fixed support 140 is arranged at the bottom of the upper cover assembly 200 as a part of the upper cover assembly 200.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, and not to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the utility model can be modified or replaced equivalently without departing from the essence and scope of the technical solutions of the utility model.
