Description

A kind of air draft mechanism applied in blower of cleaner
Technical field
The utility model relates to cleaner installations technical field more particularly to a kind of air drafts applied in blower of cleaner Mechanism.
Background technique
It is well known that dust catcher why can the rubbish such as suctioning dirt and hair, be because its suction inlet periphery have High negative pressure, and motor of dust collector fan blade is a main component for generating negative pressure.This negative pressure is to measure dust catcher to inhale Enter important indicator of power either suction efficiency, it is related with the technical performance of motor, more be integrally connected The structure of impeller of blower has the association that can not ignore.Therefore all the time technical staff in order to improve the work of dust catcher electric fan Make efficiency other than studying motor performance, considerable energy has also been poured on impeller of blower.The blower wind of the prior art Leaf is mainly made of upper leaf dish, lower leaf dish and multiple blade three parts, and wherein blade is clipped between upper and lower leaf dish in the shape of a spiral Even arrangement, upper leaf dish center are provided with a circular hole, and as air inlet, they are installed between the fan housing of blower and inducer.
When electric fan work, impeller of blower high speed rotation, and air is aspirated, air-flow enters from circular hole, through blade and leaf Between piece air duct discharge, and enter inducer, be then exported outside electric fan, at this moment air inlet produce one it is quite high Negative pressure.Occur wind short circuit phenomenon in order to influence the air that fan blade is discharged by air inlet negative pressure and (gas of fan blade is discharged Flow some and be split and be returned to air inlet, part sucking power can be lost in this way, make the work efficiency drop of dust catcher), The prior art is that the edge of the air inlet circular hole of upper leaf dish is dug upwards, a tubular flange is formed, at the same time on fan housing Corresponding air inlet also to lower flange, or even setting twice flange, is buckled in the inside and outside wall of flange of leaf dish.Exist in this way It is provided with one of wind loop on the path of shunting, forms certain windage, to reduce the loss of sucking power.
Although being provided with one of obstacle in air inlet, since fan blade runs at high speed, generated air pressure is very high, only leans on This one of wind loop is also not enough to totally block shunting.Because lower flange can not tightly be attached to one in set twice Rise, must there are some gaps, thus inevitably also have a little shunt generate.
Utility model content

Preferably, the first wind shielding structure and the second wind shielding structure are bent downwardly to form by the lower end surface annular of fan housing, And first wind shielding structure and the second wind shielding structure include annular flange at least together, annular flange is respectively close to the first flange With the second flange.
Preferably, the first wind shielding structure and the second wind shielding structure include twice annular flange, the ring of the first wind shielding structure Shape flange is respectively close to the outboard sidewalls of the first flange, and the twice annular flange of the second wind shielding structure is respectively close to the second flange Outboard sidewalls.
Preferably, the first flange upper end is protruded between the twice annular flange of the first wind shielding structure, the second flange upper end is stretched Enter between the twice annular flange of the second wind shielding structure.
Preferably, the first wind shielding structure and the second wind shielding structure include annular flange together, the ring of the first wind shielding structure Inner sidewall of the shape flange close to the first flange, the lateral wall of the annular flange of the second wind shielding structure close to the second flange.
Preferably, impeller of blower includes upper leaf dish, lower leaf dish and several spiral shells being set between leaf dish and lower leaf dish Revolve the evenly distributed blade of shape, and the connected lower leaf dish of the output shaft of blower of cleaner from bottom to top.
Preferably, the structure in the rounded hole of air inlet.
Preferably, the first flange and the second flange are cylindrical in shape structure.
The beneficial effect of above-mentioned technical proposal is:
It include impeller of blower and fan housing applied to the air draft mechanism in blower of cleaner, and the upper leaf dish upper end of impeller of blower Face has inside and outside two circles flange, the wind shielding structure that fan housing lower end surface has two circles opposite with flange position, and common shape each other At twice wind loop, to be provided with twice wind loop on the path of gas distribution, biggish windage is formd, it can be preferable Reduce electric fan sucking power loss so that working efficiency is higher, and overall structure is relatively simple, and implementation cost is lower, But effect is clearly.
