Abstract

The invention relates to a heat radiator for a vacuum cleaner, comprising a back cover arranged at the outside of a micro motor chassis and a hose connecting the back cover and a pipe on the top part of a suction head, wherein the hose is connected with the inner side of the back cover through an air vent arranged on the back cover of the micro motor; the hose connected with the outer side of the chassis is internally communicated with the pipe on the top part of the suction head. When roll brushes are rotated under the drive of the micro motor, the heat produced during the motor rotation enters the hose from the inner side of the back cover, flows along the hose to the pipe on the top part of the suction head, and then is sucked away along with the sucking air. Therefore, the invention has the advantages that the temperature of the micro motor during rotation is considerably reduced by the heat radiator of the motor, which solves problems of shortened motion life of components and deformation of the back cover of the casing due to a large amount of heat produced by micro motor.

Description

Motor heat extraction device for dust aspirator
Technical field
The present invention relates to dust catcher, particularly relate to the motor of dust catcher.
Background technology
Dust catcher is a kind of household electrical appliance of indoor cleaning health, is used for removing the dust in ground, carpet, wall, furniture and various slits.Dust catcher mainly is made of suction nozzle, disposal box, aspirator and housing, with motor and blower fan is that the aspirator that becomes of dominant shape and the disposal box that has filter are arranged in the housing, and the air entry of the oriented under shed of suction nozzle also communicates by the air inlet of air intake duct with the housing inner blower.During the dust catcher running, the impeller high speed rotating of motor drives blower fan discharges the air in the dust catcher, forms instantaneous vacuum in dust catcher, and forms a quite high Negative Pressure Difference between the ambient atmosphere.Under the effect of this Negative Pressure Difference, near the dust the suction nozzle is drawn in the disposal box in the housing by air entry and by air intake duct together with air.After filtering, the exhaust outlet from housing flows back to the dust catcher outside to the air that contains dust again in disposal box.Like this, just reach the effect of dust out, clean floor.The suction rate of dust catcher is divided into a plurality of class of operating control, adapts to the scope of operation of different cleaning objects such as ground, bed surface, sofa, corner, so that aspirate dust everywhere better.
In general, dust catcher can be divided on the profile vertical and horizontal.Dress disposal box in the horizontal dust collector housing approximate circle cone, thin slightly first half, thick slightly latter half of built-in motor and blower fan, suction nozzle separate with housing and are connected by long air intake duct.Vertical type dust collector housing approximate circle tubular, built-in motor and blower fan, suction nozzle are arranged on housing bottom and are connected by short air intake duct.
Fig. 1 is the appearance assumption diagram of a kind of vertical type dust collector of prior art.
Fig. 2 a and Fig. 2 b are the partial interior structure chart of dust catcher shown in Figure 1.
As shown in the figure, there is roller 3 the base both sides of the housing 1 that dust catcher is upright, and there is the suction nozzle 4 on the base that is installed in housing 1 in the place ahead of roller 3.The air entry ground proximity that suction nozzle 4 opens wide downwards, the round brush 8 that twines bristle on roller bearing with " S " type is arranged in the suction nozzle 4, suction nozzle 3 tops are provided with conduit 9, conduit 9 connects with the flexible pipe 5 that is connected of suction nozzle 3 outsides, the other end that connects flexible pipe 5 is connected on the housing 1, and the air intake duct through housing 1 inside is communicated with the air inlet on disposal box 6 tops again.Disposal box 6 is arranged on the recess backward of front, housing 1 middle part, and the gas outlet of disposal box 6 bottoms is communicated with blower fan one side.Blower fan and the coaxial installation of motor, the blower fan opposite side is communicated with the exhaust outlet 2 of housing.The handle of upwards erectting 7 is arranged at the top of housing 1, has power supply to connect switch on the handle 7, can move and operate dust catcher by handle 7.
Motor drives blower fan rotation in the housing 1 also produces suction force, suction nozzle 4 aspirates near the dust it together with air, aspirated the air that has dust of advancing by suction nozzle 4, enter outside connection flexible pipe 5 from the conduit 9 at suction nozzle 3 tops, enter in the housing 1 from connecting flexible pipe 5 again, enter disposal box 6 through the air intake duct in the housing 1, filtered by disposal box 6, the air process blower fan behind the filtration dust flows back to the dust catcher outside from the exhaust outlet 2 of housing.
When suction nozzle 4 suction airs, the round brush 8 in the suction nozzle 4 rotate, and the ground that is cleaned of brush continuously, make floor-dust easier of suction nozzle 4 inspirations.Round brush 8 is driven by electrical micro-machine 11, and electrical micro-machine 11 drives round brush 8 by driving belt 10 and rotates.
The electrical micro-machine 11 of dust catcher is a kind of low-power machine, and rated current is little.In service in 8 rotations of driven by motor round brush, because driving belt 10 produces a large amount of heat with round brush 8, when electrical micro-machine 11 engagements are rotated, thus the distortion that can reduce the sport life span of parts and cause housing 1 base plate.The problems referred to above that the vertical type dust collector that utilizes the micro motor for driving round brush to rotate of prior art exists influence the normal use of dust catcher.
Summary of the invention
The problems referred to above that exist at the dust catcher of prior art, the present invention is by being provided with the bottom that is communicated with the suction nozzle top duct on the electrical micro-machine chassis, the heat that the electrical micro-machine rotation is produced is taken away with the air of suction with the outside flexible pipe that is connected by the conduit at suction nozzle top, produces the problem that a large amount of heat reduces the sport life span of parts and causes the housing bottom deformation with solution because of electrical micro-machine.
Motor heat extraction device for dust aspirator involved in the present invention is included in the bottom that is provided with on the electrical micro-machine chassis, connects the flexible pipe of electrical micro-machine bottom and suction nozzle top duct.The electrical micro-machine bottom is arranged on the outside on chassis, and the electrical micro-machine bottom is provided with fixture, and the middle part of fixture is provided with air vent hole.The electrical micro-machine bottom outside is connected with flexible pipe, and flexible pipe is fixed on the bottom by fixture.One end of flexible pipe inserts in the air vent hole and with the inboard of bottom and is communicated with, and the other end of flexible pipe is connected on the conduit at suction nozzle top and with catheter interior and is communicated with.
The micro motor for driving round brush rotate in service, the heat that the electrical micro-machine rotation produces can enter flexible pipe from the bottom inboard, enters the conduit at suction nozzle top again along flexible pipe.The conduit at suction nozzle top is the dust of dust catcher blower fan suction and the only way which must be passed of air, enters the heat of the electrical micro-machine generation of suction nozzle top duct, can be taken away with the air of suction.Therefore, the motor heat release reduces the temperature of electrical micro-machine in the rotating operation greatly, has solved the sport life span and the problem that causes the housing bottom deformation that reduce parts because of a large amount of heat of electrical micro-machine generation.
