Description

Technical Field

[0001] This utility model relates to a handheld fan technology, and more particularly to a handheld fan with atomizing and humidifying function. Background Technology

[0002] Current handheld fans typically only have the function of blowing air, but in hot environments, relying solely on airflow is often insufficient for rapid cooling. If the fan could also atomize and humidify while blowing air, it could achieve a rapid cooling effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to propose a handheld fan with atomizing humidification and rapid cooling function, wherein the direction of the sprayed mist airflow is deviated from the axis of the air outlet.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0005] A handheld fan with atomizing and humidifying function is provided, including a main body and a handle. The main body includes a duct shell and a fan assembly inside the duct shell. An air outlet is provided at the front end of the duct shell. The handle includes a handle shell and a water tank disposed inside the handle shell. The top of the handle shell is connected to the duct shell. A water-absorbing rod is provided inside the water tank. The lower end of the water-absorbing rod extends to the bottom of the water tank, and the upper end of the water-absorbing rod is in close contact with an atomizer. An angled mist outlet is provided inside the air outlet, and the atomizer is disposed between the angled mist outlet and the water-absorbing rod.

[0006] Furthermore:

[0007] The air duct housing is equipped with a motor mounting bracket for fixing the motor, and the angled mist outlet is located inside the motor mounting bracket.

[0008] The water-absorbing rod includes an upper section and a lower section. The upper section is a square column with its top surface being a beveled surface that is at the same angle as the inclined mist outlet.

[0009] The handle also includes a rechargeable battery and a control circuit board. The rechargeable battery is arranged longitudinally parallel to the water tank, which is located near the air outlet. The control circuit board is located above the rechargeable battery.

[0010] The outer shell of the air duct is cylindrical, and an air inlet screen is provided at the rear end.

[0011] The duct housing also includes a display circuit board and a display screen, which is coaxially arranged with the motor of the fan assembly and located in front of the motor, and the air outlet is arranged around the display screen.

[0012] The handle housing is equipped with a power switch and a spray button, which are vertically positioned between the rechargeable battery and the control circuit board.

[0013] The oblique mist outlet is located directly below the air outlet, and its mist outlet direction is obliquely upward.

[0014] The top of the handle housing is provided with a sloping groove for mounting an atomizer.

[0015] Compared with the prior art, the present invention has the following technical effects: the air outlet is provided with an oblique mist outlet that is in close contact with the bottom surface of the atomizer. When the atomizer is working, the mist will be sprayed along the oblique mist outlet channel. The obliquely sprayed mist will not directly spray onto the user's skin surface. At the same time, the atomization diffusion area will also be effectively expanded, which can effectively improve the atomization diffusion and humidification and cooling effects.

A water-absorbing rod 250 is disposed within the water tank 220, with its lower end extending to the bottom of the water tank and its upper end contacting the atomizer 250. The atomizer 250 is positioned between the angled mist outlet 113 and the water-absorbing rod 250. The water-absorbing rod 250 includes an upper section 251 and a lower section 252. The upper section is a square column, and its top surface is a beveled surface at the same angle as the angled mist outlet 113.

[0025] The handle housing 210 is provided with a power switch / spray button 211, which is arranged vertically between the rechargeable battery 230 and the control circuit board 240.

[0026] like Figure 1 and Figure 4 As shown, the air outlet 111 surrounding the display screen 140 is provided with a grille. The oblique mist outlet 113 is located directly below the air outlet 111, and its mist outlet direction is obliquely upward.

[0027] In this embodiment, the water tank 220 and the handle housing 210 are positioned by corresponding concave and convex parts on their sidewalls. The water tank 220 is provided with an outlet 221 and a filling port 222, and the filling port is provided with a duckbill valve silicone cap 223. The outlet 221 is provided with an O-ring silicone ring and a water-absorbing rod fixing sleeve 224 is installed. A spring 225 and a water-absorbing cotton swab 250 are installed inside the water-absorbing rod fixing sleeve 224.
