Description
Technical field
The invention belongs to daily small household appliances manufacturing technology field, specifically, relate to a kind of Pneumatic floor brush and empty true dust catcher thereof.
Background technology
Present dust catcher generally includes dirt bucket, filter assemblies and electric machine assembly, and dirt bucket, filter assemblies and electric machine assembly are positioned at a housing, and electric machine assembly is connected with described dirt bucket by filter assemblies.Electric machine assembly comprises motor and fan, after the motor energising, the drive fan blade runs up, make the inner moment vacuum that forms of dust catcher, the air pressure of dust catcher inside is significantly less than extraneous air pressure, under the effect of this draught head, dust and dirt are along with air-flow enters in the dirt bucket of dust catcher along suction nozzle and air channel, pass through the filtration of filter assemblies again, dust and dirt is stayed in the dust bag of filter assemblies, the air that purifies then reenters indoor through motor, the effect that play cool motors, purifies air.Vacuum cleaner utilizes its built-in Motor Drive blower fan and produces negative pressure and carries out dedusting, it can not fly upward by dust when operation is used, and can absorb the dirt bits that reach general not easy-clear on the carpet in the slit, and easy to use, simple to operate, be widely used in family and the public place.
In the vacuum cleaner that uses at present, the structure of Pneumatic floor brush has several forms in the vacuum cleaner, a kind of form as shown in Figure 1, dust-contained airflow enters round brush chamber 1 by the scrubbing brush suction port, enters turbine room 2 by round brush chamber 1 again and enters the dirt bucket through the air channel again, and the less dust of the dust that particle is bigger and particle all will pass through turbine room 2, Pneumatic floor brush at said structure, in turbine room 2, if the gap between turbine room inwall 3 and the impeller 4 is big, then the impeller load capacity is poor; If the gap between turbine room inwall 3 and the impeller 4 is little, the dust that then particle is bigger can stuck impeller.In this structure, there is not cleaning gas tream to enter the air channel, namely dust-contained airflow drives the turbine rotation, drives the round brush rotation by the turbine rotation again.
As shown in Figure 2, also have a kind of Pneumatic floor brush, have two inlet channels, the dust-contained airflow that is sucked by suction port directly enters the air channel by round brush chamber 1, and without turbine room 2, cleaning gas tream enters turbine room by air entry, directly enter the air channel by turbine room 2, without the round brush chamber.Owing to only drive the turbine rotation with cleaning gas tream, so this technology can solve the easy stuck problem of turbine among Fig. 1.Because the air-flow through turbine room directly enters air channel 7, does not take away dust, this part air-flow is not fully utilized.
(patent No.: 96110179.2) disclosed a kind of ground brush configuration, dust-contained airflow is after sucking the round brush chamber through the scrubbing brush suction port, to enter the air channel again in " vacuum cleaner that contains suction nozzle main body " Chinese patent; The turbine air-intake of cleaning gas tream from this scrubbing brush sucks, and the air-flow of suction is supplied with the turbine moment that rotates and driven the turbine rotation, and the round brush that is installed on the same axle with turbine is also driven rotation simultaneously.Wherein, the cleaning gas tream that turbine air-intake sucks flows into the round brush chamber again through behind the turbine room, makes this part cleaning gas tream can also carry dust and enters the air channel, and namely this cleaning gas tream also has after driving the turbine rotation and carries the effect that dust enters the air channel.But because turbine and round brush are coaxial settings, turbine can not be done greatly, thereby has the defective of load capacity difference.
Summary of the invention
In order to solve the deficiencies in the prior art, the invention provides a kind of Pneumatic floor brush, described Pneumatic floor brush comprises housing, round brush and turbine, described housing is provided with the round brush chamber that holds described round brush respectively and holds the turbine room of described turbine, the described round brush rotation of described turbine drive, dust-contained airflow enters described round brush chamber by the suction port of housing setting, cleaning gas tream enters described turbine room by the air entry of housing setting, between described round brush chamber and the turbine room drainage channel is set, the cleaning gas tream of flowing through behind the turbine room enters described round brush chamber by described drainage channel, described round brush and described turbine disalignment.
Described Pneumatic floor brush also arranges the air channel, and dust-contained airflow enters from suction port that the round brush chamber is laggard goes into the air channel; Cleaning gas tream enters turbine room from air entry, enter the round brush chamber by drainage channel after, enter the air channel again.The axis of described round brush is in different horizontal planes with the axis of turbine.
Described turbine is radial fan, axial fan or mixed flow fan.
The present invention also provides a kind of vacuum cleaner, described main body of dust collector and the Pneumatic floor brush of comprising, main body of dust collector and Pneumatic floor brush are connected, be provided with the electric fan unit in the main body of dust collector, for generation of suction force, wherein said Pneumatic floor brush is above-mentioned Pneumatic floor brush as vacuum generator in the electric fan unit.
The invention solves the easily problem of stuck or load force difference of turbine, make again and be fully used through the air-flow of turbine, improved cleaning efficiency.
