Conveniently-dismounted fan capable of achieving lighting

Abstract

The invention discloses a conveniently-dismounted fan capable of achieving lighting. The conveniently-dismounted fan comprises a shell, a handle, a motor, an LED searchlighting light source, a water tank, a locking part, a hub and blades; the shell comprises a front shell and a back shell, the handle is fixed to the top of the shell, a closed containing cavity is formed between the front shell and the back shell, and the motor and the searchlighting light source are both contained in the containing cavity; the water tank is detachably arranged inside the fan shell, the water tank and the fan shell are locked through the locking part; and the side face, facing the air outlet side of the fan, of the hub is provided with a plurality ridge-shaped protrusions distributed in the circumferential direction. When the hub rotates, the ridge-shaped protrusions enable air to flow, the air amount is increased, and the fan efficiency is improved; the torch searchlighting function is increased, and therefore the auxiliary lighting effect is achieved; and when the locking part is used, the water tank and the fan shell can be controlled to be in the locking state, and therefore the water tank has the characteristic of being convenient to dismount and mount.

Description

technical field [0001] The invention belongs to the technical field of air supply equipment, and in particular relates to an illuminating and conveniently detachable fan. Background technique [0002] A fan refers to an electric fan used to generate wind to keep cool in hot weather. It is a device driven by electricity to generate air flow. [0003] A traditional fan includes a hub and a plurality of blades. The hub is disc-shaped, and its center is the fan installation area, which is used to connect with the driving equipment that drives the fan to rotate. The outer ring area of ​​the hub is the installation area of ​​the blades, and the blades are fixedly connected. in the installation area. When the fan is driven by the driving device and rotates to work, the rotation of the fan blades forces the air to flow out from the air outlet side of the fan. However, because the existing fan is flat on the entire hub, no wind pressure will be generated on the air outlet side of th...

AI Technical Summary

Problems solved by technology

When the fan is driven by the driving device and rotates to work, the rotation of the fan blades forces the air to flow out from the air outlet side of the fan. However, because the existing fan is flat on the entire hub, no wind pressure will be generated on the air outlet side of the hub area. Therefore, the pressure on the end surface of the hub on the air outlet side is lower than the pressure on the surrounding area, resulting in backflow near the end surface of the hub on the fan outlet side, reducing the air volume of the fan and reducing the efficiency of the fan. This is due to the traditional fan hub. The structural design only considers the installation method of the fan blades, but does not consider how to prevent backflow

The water tank of the electric fans (such as cooling fans) sold in the market is connected with the fan housing by screws. Since the two are connected by screws, when the user disassembles the water tank, it is necessary to use a matching disassembly tool, which is inconvenient for disassembly and assembly. question

Moreover, the commonly used fan has a single function. Except for the role of fan in summer, the fan is idle at other times. With many different applications, other functions of the fan are required. For example, in dark and hot conditions, in addition to being able to play In addition to the fan effect, it also needs to have a lighting effect
