Description

Technical Field

[0001] The utility model relates to the technical field of humidifiers, in particular to a humidifier with an improved float seesaw structure. Background Art

[0002] A top-water humidifier is a type of humidifier that allows water to be added directly from above the humidifier. It typically features a removable water tank above the humidifier base, allowing water to be added directly to the tank. This type of humidifier has an atomizing chamber at the base, and the water tank's outlet supplies water to the chamber and is equipped with a drain valve. A seesaw float is located in the chamber, which can float and deflect as the water level in the chamber rises and falls, controlling the opening and closing of the drain valve. For example, Patent No. CN201820782946.1 discloses a seesaw water supply assembly and a humidifier.

[0003] Existing float seesaws are typically composed of two plastic shells, welded together by hot-melt welding, with an air cavity formed between them. To stabilize the float's weight, a metal counterweight is typically fixed within the air cavity. However, this combined structure of two plastic shells is prone to water leakage and seepage over long periods of use, altering the overall weight of the float seesaw and reducing its floating stability, even preventing the drain valve from closing or opening. Furthermore, the metal counterweight can easily rust, affecting the cleanliness of the water in the atomization chamber. Therefore, further improvements are needed. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems in the prior art. To this end, the utility model provides a humidifier with an improved float seesaw structure.

[0005] An embodiment of the present invention solves the technical problem by adopting a technical solution: a humidifier with an improved float seesaw structure, comprising a base and a water tank disposed above the base; the base is provided with an atomizing chamber, a water outlet of the water tank can supply water to the atomizing chamber and is provided with a drain valve; the float seesaw is disposed in the atomizing chamber and can float and swing with the rise and fall of the water level in the atomizing chamber, and controls the conduction or closing of the drain valve;

[0006] The float seesaw includes a head end, a rotating shaft portion and a top end which are integrally formed by injection molding; the rotating shaft portion is rotatably mounted on the base; the head end and the top end are respectively located at opposite ends of the rotating shaft portion; the top end is located below the water outlet; an upwardly concave exhaust groove is provided below the head end as a whole; an upwardly penetrating exhaust hole is provided at the head end and is connected to the exhaust groove.

[0007] Optionally, the upper end of the recess is a first inclined guide surface; and the exhaust hole is arranged close to the top of the first inclined guide surface.

[0008] Optionally, an extension arm is provided between the head end and the rotating shaft portion, and the extension arm is provided in a long strip structure; the top end and the exhaust hole are arranged at opposite ends of the extension arm in a straight extension direction.

[0009] Optionally, the extension arm is a hollow structure opening downward, and a reinforcing rib is provided inside the extension arm.

[0010] Optionally, the lower side of the head end is a second inclined guide surface, and the second inclined guide surface is inclined upward on a side away from the rotating shaft.

[0011] Optionally, the base is provided with an atomization component and a power plug component.

[0012] The beneficial effects of this utility model are as follows: the float seesaw includes an integrally injection-molded head end, a rotating shaft, and a top end; an upwardly concave exhaust groove is provided below the head end, replacing the conventional spliced ​​air cavity structure, and the head end is provided with a wide exhaust hole extending upward and downward to exhaust air within the exhaust groove. Because the float seesaw is integrally injection-molded, the utility model eliminates air cavities that could allow water to seep in and accumulate. Furthermore, during floating, air within the exhaust groove can be promptly discharged through the exhaust hole, resulting in no change in the buoyancy of the float seesaw. The float seesaw has high floating deflection stability, ensuring a stable and reliable humidifier water tank filling process.

[0025] Example

[0026] Reference Figures 1 to 4 The present invention proposes a humidifier with an improved float seesaw 30 structure, comprising a base 10 and a water tank 20 disposed above the base 10; the base 10 is provided with an atomizing chamber 11, a water outlet 21 of the water tank 20 can supply water to the atomizing chamber 11 and is provided with a drain valve; the float seesaw 30 is disposed in the atomizing chamber 11 and can float and deflect as the water level in the atomizing chamber 11 rises and falls, thereby controlling the opening or closing of the drain valve;

[0027] The float seesaw 30 includes an injection-molded integral head end 31, a rotating shaft portion 32, and a top end 33; the rotating shaft portion 32 is rotatably mounted on the base 10; the head end 31 and the top end 33 are respectively located at opposite ends of the rotating shaft portion 32; the top end 33 is located below the water outlet 21; an upwardly recessed exhaust groove 311 is provided below the head end 31 as a whole; the head end 31 is provided with an upwardly penetrating exhaust hole 312, which is connected to the exhaust groove 311.

[0028] In the present invention, the float seesaw 30 includes an integrally injection-molded head end 31, a rotating shaft portion 32, and a top end 33. An upwardly recessed exhaust groove 311 is provided below the head end 31, replacing the conventional composite air cavity structure. Furthermore, the head end 31 is provided with a wide exhaust hole 312 extending vertically to exhaust air within the exhaust groove 311. In the present invention, since the float seesaw 30 is integrally injection-molded, there is no air cavity where water can seep in or accumulate. Furthermore, during the floating process, air within the exhaust groove 311 can be promptly exhausted through the exhaust hole 312. Consequently, the buoyancy of the float seesaw 30 remains unchanged, resulting in high floating and deflection stability. The immersion of the humidifier water tank 20 is stable and reliable.

[0029] Specifically, the upper end of the depression is the first inclined guide surface 313, and the exhaust hole 312 is provided near the top of the first inclined guide surface 313. When the water level rises, the first inclined guide surface 313 guides the internal air to flow toward the exhaust hole 312 at the top.

[0030] In this embodiment, an extension arm 34 is disposed between the head end 31 and the shaft portion 32. The extension arm 34 is configured as an elongated strip. The top end 33 and the vent 312 are located at opposite ends of the extension arm 34's linear extension. The extension arm 34 extends the torque between the head end 31 and the shaft, allowing for more sensitive thrust applied to the drain valve through the top. Furthermore, the vent 312 is located close to the extension arm 34, minimizing vibration or shaking during the venting process.

[0031] Preferably, in order to reduce the weight of the extension arm 34 and improve the strength of the extension arm 34 , the extension arm 34 is a hollow structure with an opening facing downward, and a reinforcing rib 35 is provided inside the extension arm 34 .

[0032] In this embodiment, the underside of the head end 31 is provided with a second inclined guide surface 314, which is tilted upward on the side away from the rotation axis. This second inclined guide surface 314 gradually discharges some air toward the outside of the head end 31 during floating yaw, thereby reducing head shaking.

[0033] In this embodiment, the base 10 is provided with an atomizing assembly and a power plug assembly. The power plug assembly can be used by directly plugging a power cord into a power socket; or by splicing multiple sections of detachable terminals, power cords and adapters.

[0034] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
