Description
Technical field
The utility model relates to a kind of electric floor scrubber for cleaning floor, specifically a kind of device that can change the round brush rotating speed of electric floor scrubber.
Background technology
The rotating speed of electric floor scrubber round brush that the dust catcher of cleaning carpet uses in the market is changeless substantially, and its rotating speed is also higher, is also very effective for dust suction on carpet.Just there is a problem, namely in the operating process of dust suction, floor cleaner brush generally has the process of individual push and pull repeatedly, because the rotating direction of round brush is consistent with the direction that floor cleaner brush advances, one row's hairbrush of round brush has certain grip that floor cleaner brush can be driven to move forward to carpet, so it is not the propelling of floor cleaner brush is very laborsaving, just light when drawing conversely, compare effort.This brings inconvenience just to large area cleaning carpet.Just must manage to alleviate the grip of hairbrush to carpet to alleviate dilatory force, but can not dust suction be affected, therefore only have the rotating speed relatively lowering round brush, to alleviate the grip of hairbrush to carpet.
Summary of the invention
The purpose of this utility model is defect for above-mentioned prior art and deficiency, for people provide a kind of device that can reduce round brush rotating speed when electric floor scrubber post-tensioning.
Technical solution adopted in the utility model is for achieving the above object: the speed change gear of this electric floor scrubber comprises the housing of electric floor scrubber, round brush is provided with at the lower front of housing, motor and wiring board is provided with in housing, motor can drive round brush to rotate, described wiring board is provided with bridge rectifier, two outputs of this bridge rectifier are connected with motor, and two inputs are connected with power supply;
Described wiring board is provided with travel switch, and two normally-closed contacts of the trip switch are connected with motor, and its normally opened contact is connected with the input of bridge rectifier; When travel switch is not closed, power supply provides full wave voltage by bridge rectifier to motor, and when travel switch closes, power supply, by the single diode rectification in bridge rectifier, provides half-wave voltage to motor;
One press part is set in described housing, when this press part moves after housing and travel switch offset, make travel switch close, leave travel switch when housing moves forward, travel switch opened.
Described press part is the roller that can move forward and backward, and the base section of roller exposes housing, and when housing moves forward and backward, the hair energy jog dial of carpet moves; Described travel switch is positioned at the front side top of roller motion track, can offset during roller reach with the travel switch arm of force, and travel switch is closed.
The base plate of described housing covers capping plate, roller activity is flush-mounted between the base plate of housing and cover plate, and the upper/lower terminal of roller is revealed in outside the elongated slot that is opened on base plate and cover plate respectively.
Be provided with chute between described base plate and cover plate, be equipped with rotating shaft at the center of roller, the two ends activity of rotating shaft is flush-mounted in chute.
The utility model when cleaning carpet, woollen blanket, the rotating speed of round brush can push away before the scrubbing brush of base area or post-tensioning motion and change.When namely pushing away before floor cleaner brush, roller is allocated to rear side by woollen blanket, leaves travel switch, and power supply, by bridge rectifier, provides full wave voltage to motor, and now the rotating speed of round brush is fast, and cleaning effect is good.During floor cleaner brush post-tensioning, roller is allocated to front side by woollen blanket, offset with the arm of force of travel switch, travel switch is closed, and power supply, by the single diode rectification in bridge rectifier, provides half-wave voltage to motor, the rotating speed of round brush is slow, reduce resistance when pulling, make to pull more light, there is the advantage that structure is simple, easy to operate.

Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model is a kind of speed change gear of electric floor scrubber, and it comprises the housing 3 of electric floor scrubber, is provided with round brush 2 at the lower front of housing 3, is provided with motor M D and wiring board 1, motor M D can drive round brush 2 to rotate in housing 3.Described wiring board 1 is provided with bridge rectifier, and this bridge rectifier comprises four diodes D1, D2, D3, D4 and two outputs, two inputs, and two outputs are connected with motor M D, and two inputs are connected with power supply.Described wiring board 1 is provided with travel switch SQ1, and two normally-closed contacts of the trip switch S Q1 are connected with motor M D, and its normally opened contact is connected with the input of bridge rectifier; When stroke switch S Q1 is not closed, the positive half cycle of power supply sine wave is by diode D1, D4 rectification, and negative half period is by diode D2, D3 rectification, and therefore electric current provides full wave voltage by bridge rectifier to motor M D, makes round brush 2 quick rotation.When stroke switch S Q1 closes, the positive half cycle of power supply sine wave is by the single diode D1 rectification in bridge rectifier, and negative half period cannot export, and therefore electric current only provides half-wave voltage to motor M D, and the rotating speed of round brush 2 reduces.
In order to reach allow round brush 2 push away before floor cleaner brush time rotating speed very fast, the object of round brush 2 rotating speed is reduced when post-tensioning, in housing 3, a press part can be set, when this press part moves after housing 3 and travel switch SQ1 offset, travel switch SQ1 is closed, leave travel switch SQ1 when housing 3 moves forward, travel switch SQ1 is opened.
As shown in Figure 3, Figure 4, the utility model adopts movable roller 8 as press part, the base plate 5 of described housing 3 covers capping plate 6, and roller 8 activity is flush-mounted between the base plate 5 of housing 3 and cover plate 6, and the upper/lower terminal of roller 8 is revealed in respectively and is opened in base plate 5 with outside the elongated slot on cover plate 6.Be provided with chute 7 between described base plate 5 and cover plate 6, be equipped with rotating shaft 9 at the center of roller 8, the two ends activity of rotating shaft 9 is flush-mounted in chute 7.Base section due to roller 8 exposes housing 3, and when housing 3 moves forward, the hair energy jog dial 8 of carpet moves backward, and when moving after housing 3, the hair energy jog dial 8 of carpet moves forward.Described travel switch SQ1 is positioned at the front side top of roller 8 motion track, can offset when roller 8 moves forward with the arm of force 4 of travel switch SQ1, and travel switch SQ1 is closed.
The utility model when cleaning carpet, woollen blanket, the rotating speed of round brush 2 can push away before the scrubbing brush of base area or post-tensioning motion and change.When namely pushing away before floor cleaner brush, roller 8 is allocated to rear side by woollen blanket, leaves travel switch SQ1, and power supply, by bridge rectifier, provides full wave voltage to motor M D, and now the rotating speed of round brush 2 is fast, and cleaning effect is good.During floor cleaner brush post-tensioning, roller 8 is allocated to front side by woollen blanket, offset with the arm of force 4 of travel switch SQ1, travel switch SQ1 is closed, and power supply, by the single diode rectification in bridge rectifier, provides half-wave voltage to motor M D, the rotating speed of round brush 2 is slow, reduce resistance when pulling, make to pull more light, there is the advantage that structure is simple, easy to operate.
