[0027] See Figure 1 , Figure 2 and Figure 3This application discloses a humidifier. The humidifier includes a housing 1, an observation window 2, a float 3, a linkage 4, and an indicator rod 5. In some embodiments, the observation window 2 is disposed on the housing 1; the float 3 is disposed inside the housing 1 and can float within the housing 1; the linkage 4 is pivotally connected to the housing 1, and the float 3 is fixedly connected to the linkage 4; one end of the indicator rod 5 is fixedly connected to the linkage 4, and the other end of the indicator rod 5 extends to the observation window 2. When the float 3 floats within the housing 1, it can drive the linkage 4 to rotate, and the rotation of the linkage 4 will drive the indicator rod 5 to swing within the observation window 2. Preferably, the buoy 3 floats with the water level inside the housing 1, thereby driving the linkage 4 to rotate and causing the indicator rod 5, which is fixed to the linkage 4, to swing within the observation window 2. This allows the physical lever structure composed of the buoy 3, linkage 4, and indicator rod 5 to reflect the water level changes inside the housing 1 through the observation window 2, improving the reliability and stability of water level detection and effectively optimizing the production cost of the product.

[0028] See Figure 1 and Figure 2 In some embodiments, a transparent cover 21 is also included, which covers the observation window 2. The transparent cover 21 is provided with an indicator mark 22, which is disposed opposite to the indicator rod 5. Preferably, by covering the observation window 21 with the transparent cover 21, the user can easily observe the position of the indicator rod 5 within the observation window 2, while preventing foreign objects from passing through the observation window 2 and entering the housing 1. Furthermore, the transparent cover 21 is provided with the indicator mark 22, so that the water level within the housing 1 can be intuitively reflected based on the current position of the indicator rod 5 and the corresponding indicator mark 22. Optionally, the indicator mark 22 can be composed of one or more of numbers, letters, and words, such as full, low water, FULL, etc. In this embodiment, the indicator mark 22 includes MAX, 1 / 2, MI N. When the indicator rod 5 swings to the position opposite to MAX, it indicates that the water level in the housing 1 is full. When the indicator rod 5 swings to the position opposite to 1 / 2, it indicates that the water level in the housing 1 is half of the capacity. When the indicator rod 5 swings to the position opposite to MI N, it indicates that the water level in the housing 1 is at its minimum value.

[0029] See Figure 1 , Figure 2 , Figure 3 and Figure 5In some embodiments, the buoy component 3 includes a buoy body 31 and a central connecting rod 32. One end of the central connecting rod 32 is fixed to the linkage 4, and the other end of the central connecting rod 32 is fixed to the buoy body 31. Preferably, by providing the central connecting rod 32 between the buoy body 31 and the linkage 4, the distance between the buoy body 31 and the linkage 4 is increased, making the lever arm longer. Since torque is the product of force and lever arm, a larger torque is generated under the same force, which helps to more easily drive the linkage 4 to rotate, causing the indicator rod 5 fixed to the linkage 4 to swing within the observation window 2, further optimizing the reliability and stability of water level detection. Optionally, the buoy body 31 is an integrally formed structure, see [reference]. Figure 3 It can be made of buoyant materials, such as foam or plastic; furthermore, the buoy body 31 also has a hollow structure inside, which can further increase the buoyancy of the buoy body 31; or, the buoy body 31 is a split structure, see [reference]. Figure 5 The buoy body 31 includes a buoy cover 311 and a buoy shell 312. The buoy shell 312 is filled with a buoyant material, and the buoy cover 311 is placed over the buoy shell 312. The other end of the central connecting rod 32 is fixed to the buoy shell 312. Optionally, the buoy cover 311 and the buoy shell 312 are made of plastic. Optionally, the buoy shell 312 has an inner cavity with an opening, and the buoy cover 311 is placed over the opening to close it. Further, a sealing ring or other sealing material is provided between the buoy cover 311 and the opening to improve the sealing of the inner cavity of the buoy shell 312 and prevent water from entering the buoy shell 312. Optionally, the buoyant material includes, but is not limited to, pearl cotton, EVA cotton, etc. Optionally, the buoyant material can be replaced with other materials with a density less than water.

[0030] See Figure 1 , Figure 2 and Figure 3In some embodiments, the linkage 4 includes a linkage shaft 41, which is pivotally connected to the housing 1. The indicator rod 5 and the buoy 3 are both fixedly connected to the linkage shaft 41. Preferably, since the indicator rod 5 and the buoy 3 are both fixedly connected to the linkage shaft 41, and the linkage shaft 41 is pivotally connected to the housing 1, when the buoy 3 floats with the water level in the housing 1, it can synchronously drive the linkage shaft 41 to rotate, and drive the indicator rod 5 to swing with the linkage shaft 41 within the observation window 2, thereby realizing the use of a physical lever structure to reflect the water level change in the housing 1 through the observation window 2. Optionally, one end of the indicator rod 5 is fixedly connected to the middle connecting rod 32 away from the... At one end of the buoy body 31, the linkage shaft 41 is fixedly connected to the intersection of the indicator rod 5 and the central connecting rod 32, so that both the indicator rod 5 and the buoy component 3 are fixedly connected to the linkage shaft 41; optionally, the linkage component 4 may further include a first extension extending outward from the central connecting rod 32, and both the indicator rod 5 and the linkage shaft 41 are fixedly connected to the first extension; optionally, the linkage component 4 may further include a second extension extending outward from the indicator rod 5, and both the central connecting rod 32 and the linkage shaft 41 are fixedly connected to the second extension.

[0031] See Figure 1 , Figure 2 and Figure 3 In some embodiments, the buoy component 3, the linkage component 4, and the indicator rod 5 are integrally formed. Preferably, by integrally forming the buoy component 3, the linkage component 4, and the indicator rod 5, the overall structure formed by connecting the buoy component 3, the linkage component 4, and the indicator rod 5 has better strength and rigidity, while optimizing the number of parts, reducing assembly and processing steps, and shortening the production cycle. In this embodiment, the indicator rod 5, the linkage shaft 41, the central connecting rod 32, and the buoy body 31 are integrally formed, that is, the lever structure used to reflect the water level change inside the shell 1 is integrally formed, so that the overall lever structure has better physical properties.

[0032] See Figure 1 , Figure 2 and Figure 3 In some embodiments, the observation window 2 extends through the top wall of the housing 1. Preferably, the observation window 2 extends through the top wall of the housing 1 so that the indicator rod 5 can extend from inside the housing 1 into the observation window 2, allowing the user to check the water level without bending over. This is especially convenient when the humidifier is placed on the ground or at a low position, as the observation window 2 on the top wall of the housing 1 makes it easier for the elderly and users with mobility impairments to check the position of the indicator rod 5, effectively improving the practicality of the humidifier.

[0033] See Figure 3 In some embodiments, the buoy 3, the linkage 4, and the indicator rod 5 are connected to form an L-shaped whole. Preferably, the buoy component 3, the linkage component 4, and the indicator rod 5 are connected into an L-shaped structure, so that the physical lever structure composed of the buoy component 3, the linkage shaft 41, and the indicator rod 5 occupies less space, making it suitable for narrow spaces and avoiding interference with other components. Optionally, the L-shaped structure is made by a one-piece molding process to give it better strength and rigidity. Optionally, the indicator rod 5 extends along the height direction, and the middle connecting rod 32 of the buoy component 3 extends horizontally. One end of the indicator rod 5 is fixed to the end of the middle connecting rod 32 away from the buoy body 31, that is, the two lever arms in the lever structure are perpendicular to each other, effectively limiting the torsional freedom of the lever structure, reducing swaying in unexpected directions, and improving operational accuracy. Optionally, the linkage shaft 41 is fixed to the intersection of the indicator rod 5 and the middle connecting rod 32 (that is, the bend of the L-shaped structure), so that the linkage shaft 41 can effectively balance the torque of the two lever arms, improving the stability and efficiency of the lever.

[0034] See Figure 1 and Figure 2 In some embodiments, the housing 1 is provided with a wet curtain support 11, which divides the housing 1 into a water filling chamber 12 and a humidification chamber 13. The bottom of the wet curtain support 11 is provided with a through groove 14, which connects the water filling chamber 12 and the humidification chamber 13. The buoy 3 is disposed in the humidification chamber 13. The water filling chamber 12 is used to add water to the humidification chamber 13. Thus, during the process of adding water to the housing 1, the water added to the housing 1 first enters the water filling chamber 12, and then flows into the humidification chamber 13 through the through groove 14 at the bottom of the wet curtain bracket 11. As the water level rises, the buoy 3 gradually floats up, and drives the indicator rod 5 to swing in the observation window 2 through the linkage shaft 41. This achieves the use of a physical lever structure to reflect the water filling status in the housing 1 through the observation window 2, preventing the water flow from directly impacting the buoy 3 and causing it to fail to float properly, preventing insufficient or excessive water filling, and ensuring that the lever structure composed of the buoy 3, linkage shaft 41 and indicator rod 5 can accurately reflect the water filling status in the housing 1 during the water filling process.

[0035] See Figure 1 and Figure 2In some embodiments, a support base 42 extending along the height direction is also included. The support base 42 is disposed within the humidification chamber 13, and the linkage 4 is pivotally connected to the support base 42. Preferably, by extending the support base 42 along the height direction, the vertical space of the humidification chamber 13 is fully utilized, making the component layout more compact and effectively optimizing space utilization. Furthermore, by pivoting the support base 42 to the linkage 4, the lever structure composed of the buoy 3, the linkage shaft 41, and the indicator rod 5 is assembled within the humidification chamber 13, effectively isolating the lever structure from external environmental interference and ensuring its operational reliability and accuracy. Optionally, the support base 42 has reinforcing ribs extending along the height direction within the housing 1, so that the support base 42 and the housing 1 are integrally formed, giving the overall structure formed by the connection of the support base 42 and the housing 1 better strength and rigidity. At the same time, it can optimize the number of parts, reduce assembly and processing steps, and shorten the production cycle.

[0036] See Figure 1 , Figure 2 and Figure 4 In some embodiments, the side wall of the housing 1 is provided with a water inlet 15, the water filling cavity 12 is connected to the water inlet 15, and the water inlet 15 is covered with a cover plate 16; wherein the lower end of the cover plate 16 is provided with a flip-top pivot 17 pivotally connected to the housing 1, and the upper end of the cover plate 16 is provided with a flip-top buckle 18 detachably connected to the housing 1. Preferably, during the process of opening the water inlet 15, the flip-top buckle 18 is driven to separate from the housing 1, and then the water inlet 15 can be opened by rotating the cover plate 16 around the flip-top pivot 17, so that water can be directly added to the water filling cavity 12 through the water inlet 15 without disassembling the housing 1, simplifying the water adding steps and improving the ease of operation; during the process of closing the water inlet 15, the cover plate 16 is driven to rotate in the opposite direction around the flip-top pivot 17, and then the flip-top buckle 18 is used to engage with the housing 1 to close the water inlet 15.

[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5In some embodiments, when adding water to the housing 1, the water inlet 15 is opened, and water is directly added to the water filling chamber 12 through the water inlet 15. The water added to the housing 1 first enters the water filling chamber 12, and then flows into the humidification chamber 13 through the through groove 14 at the bottom of the wet curtain bracket 11. As the water level rises, the float 3 gradually floats up and drives the indicator rod 5 to swing in the direction of MAX in the indicator mark 22 in the observation window 2 through the linkage shaft 41. When the humidifier is humidifying, as the water level drops, the float 3 gradually drops down and drives the indicator rod 5 to swing in the direction of M IN in the indicator mark 22 in the observation window 2 through the linkage shaft 41. This realizes the use of the physical lever structure composed of the float 3, linkage shaft 41 and indicator rod 5 to reflect the water level change in the housing 1 through the observation window 2, improves the reliability and stability of water level detection, and effectively optimizes the production cost of the product.

It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
