Description

Stepped air guiding structure of bladeless fan

[ Field of technology ]

The utility model mainly relates to a stepped air guide structure of a bladeless fan.

[ Background Art ]

Conventional household fans typically include a motor and a set of blades or impellers driven in rotational motion by the motor. The set of blades is typically located within a cage that allows air flow therethrough, yet prevents human body access to the rotating blades. In some cases, however, such fans also present a risk of human being touching the set of rotating blades.

The prior art discloses a bladeless fan which is favored by people because of the smooth air flow and the absence of exposed rotating blades, so that the risk of hurting personal safety does not exist. When the air flow passes through the bladeless fan air duct, turbulence and noise are generated due to the fact that the ventilation sectional area in the air duct is repeatedly increased and decreased, or wind resistance is increased due to the fact that the sectional area is rapidly changed. The air flow in the existing bladeless fan air duct flows out freely through the nozzle, and has no flow guiding structure, so that the air outlet is uneven, and the noise is increased. In view of the foregoing, there is a need to develop a deflector liner structure and a bladeless fan for solving the above problems.

[ utility model ]

In order to solve at least one of the problems, we propose a new technical scheme, and the stepped air guide structure of the bladeless fan adopts the following technical scheme:

a stepped air guide structure of a bladeless fan comprises a shell and a fan, wherein the fan is arranged in the shell; the shell comprises an air guide part which is communicated with the fan so that air flow generated by the fan enters the air guide part;

The air guiding part is provided with a plurality of air guiding sheets in a row, and the adjacent air guiding sheets have height fall, so that air flow generated by the fan enters the air guiding part from the height fall of the adjacent air guiding sheets.

Preferably, the housing further comprises a base portion having an accessory cavity within which the fan is mounted; the base part is connected with the air guiding part so that air flow generated by the fan in the base part blows into the air guiding part.

Preferably, the air guiding part comprises an air outlet cavity and air guiding grooves arranged on two sides of the air outlet cavity, the air guiding grooves are communicated with the air outlet cavity, and the air guiding sheets are arranged in the air guiding grooves.

Preferably, one end of the air guiding groove close to the fan is a tail end, one end of the air guiding groove far away from the fan is a head end, air guiding sheets in the air guiding groove are arranged from the tail end to the head end, and the heights of the air guiding sheets from the tail end to the head end are gradually increased, so that the air guiding sheets are arranged to form a stepped structure.

Preferably, the fan extends to form a two-way exhaust pipe, and the exhaust pipes are respectively communicated with the air induction channels at two sides of the air outlet cavity.

Compared with the background technology, the utility model has the beneficial effects that:

The utility model provides a stepped air guide structure of a bladeless fan, wherein the height of a stepped air guide groove from the tail end to the head end is gradually increased, namely the height of the tail end is the lowest and the maximum, and the wind power entering from the tail end is the largest; along with the longer length of the air guiding groove, the wind power from the tail end to the head end is gradually weakened, so that the height fall of the air guiding piece from the tail end to the head end is smaller, the air flow speed of the air guiding groove is forced to be faster and faster, the weakening of the wind power is compensated, and the air flow of all parts of the air guiding part is uniform.
