Description
Technical field
The present invention relates to vacuum cleaner, particularly relate to the transmission system that vacuum cleaner micro motor for driving round brush rotates.
Background technique
Vacuum cleaner is a kind of household electric appliance of indoor cleaning health, is used for removing the dust in ground, carpet, wall, furniture and various slits.Vacuum cleaner mainly is made of suction nozzle, dust collecting box, aspirator and housing, with motor and blower fan is that the aspirator that becomes of dominant shape and the dust collecting box that has filter are arranged in the housing, and the intakeport of the oriented under shed of suction nozzle also communicates by the intake grill of sucking pipe with the housing inner blower.During the vacuum cleaner running, the impeller high speed rotating of motor drives blower fan discharges the air in the vacuum cleaner, forms instantaneous vacuum in vacuum cleaner, 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 dust collecting box in the housing by intakeport and by sucking pipe together with air.After filtering, the exhaust port from housing flows back to the vacuum cleaner outside to the air that contains dust again in dust collecting box.Like this, just reach the effect of dust out, clean floor.The suction rate of vacuum cleaner is divided into a plurality of class of operating control, adapts to the work surface of different cleaning objects such as ground, bed surface, sofa, corner, so that aspirate dust everywhere better.
In general, vacuum cleaner can be divided on the profile vertical and horizontal.Dress dust collecting 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 sucking pipe.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 sucking pipe.
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 structural drawing of vertical type dust collector shown in Figure 1.
As shown in the figure, there is roller 3 the base both sides of the housing 1 that vacuum cleaner 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 intakeport 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 outsides have the flexible pipe of connection 5 to connect, and the other end that connects flexible pipe 5 is connected on the housing 1, and the sucking pipe through housing 1 inside is communicated with the suction port on dust collecting box 6 tops again.Dust collecting box 6 is arranged on the recess backward of front, housing 1 middle part, and the air outlet of dust collecting 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 port 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 vacuum cleaner by handle 7.
When above-mentioned vacuum cleaner turns round, the rotation of motor drives blower fan also produces suction force, suction nozzle 4 aspirates near dust together with air, aspirated the air that has dust of advancing by suction nozzle 4, enter outside connection flexible pipe 5 from the top of suction nozzle 3, enter in the housing 1 from connecting flexible pipe 5 again, enter dust collecting box 6 through the sucking pipe in the housing 1, filtered by dust collecting box 6, the air process blower fan behind the filtration dust flows back to the vacuum cleaner outside from the exhaust port 2 of housing.
When suction head of suction cleaner 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 micro motor 11, and the drivign belt 10 of cover is enclosed within again on the belt pulley 9 of round brush 8 on micro motor 11 motor shafts 12, and micro motor 11 drives round brush 8 by drivign belt 10 and rotates.
Micro motor 11 is a kind of low-power machines, and rated current is little.For protection micro motor 11 is not damaged by overcurrent, be connected with current of electric overload protective device 13 (Fusebreaker) in its power supply line.In service at motor, when electric current surpassed its rated current, the little button of current of electric overload protective device 13 will be upspring, and the electric current of cutting off the electricity supply plays the effect of protection motor.When continuing to use, need press push button, it is resetted, motor is task again.
The vacuum cleaner of above-mentioned prior art, the drivign belt that connects micro motor 11 motor shafts and round brush is a flat belt, motor reel that contacts with drivign belt and round brush belt pulley have even surface, see Fig. 3 a, Fig. 3 b and Fig. 4 a, Fig. 4 b.Therefore, after belt is aging, drivign belt and motor shaft and round brush belt pulley contact that frictional force reduces between the cylinder, round brush is held onto and makes the current of electric increase easily by foreign matter.When current of electric surpassed its rated current, the current of electric overload protective device will be cut off the electricity supply, and stops vacuum cleaner work.The normal use of the problems affect vacuum cleaner that above-mentioned vacuum cleaner exists.
Summary of the invention
The problems referred to above that exist at the vacuum cleaner of prior art, the present invention will comprise that the dust aspirator transmission agent of drivign belt, motor shaft and round brush belt pulley adopts the V-type member, increase frictional force between the member, reduce because of round brush is fettered by foreign matter making the current of electric overrate make the out-of-work situation of vacuum cleaner.
The V-structure of dust aspirator transmission agent involved in the present invention comprises and is enclosed within on micro motor motor shaft and the round brush belt pulley and the V-type round brush belt pulley of the cylinder concave-convex surface of the micro motor V-type motor shaft of the V-type drivign belt of its inner face concave-convex surface, the cylinder concave-convex surface that contacts with drivign belt, drivign belt contact.
The inner face of V-type drivign belt concave-convex surface, longitudinally chase and projection alternately, the chase of belt section is " V " font.On the cylinder of micro motor V-type motor shaft concave-convex surface, the chase of ring-type and annular projection alternately, the cross section of annular projection is down " V " font.On the cylinder of V-type round brush belt pulley concave-convex surface, the chase of ring-type and annular projection alternately, the cross section of annular projection is down " V " font.
When the V-type drivign belt was enclosed within on the V-type motor shaft of micro motor and the V-type round brush belt pulley, the cross section that the annular projection of the annular projection of micro motor motor shaft cylinder and round brush belt pulley cylinder inserts drivign belt was in the chase of " V " font.
The V-structure of dust aspirator transmission agent involved in the present invention more closely cooperates drivign belt and micro motor motor shaft and round brush belt pulley; obviously improve the sport life span of drivign belt; reduce the bad working condition of current of electric overload protective device, ensure the normal use of vacuum cleaner.
