This electric cleaning brush 10 during operation, even the hand lever 11 lifts too high, on the direction of rolling, the contained angle of first axis x and ground at hand lever 11 place is too big, nevertheless because the biggest effective working length of corresponding brush hair diminishes, so, brush layer and by the reversal of electric cleaning brush 10 can not lead to by the frictional force that produces between the cleaning surface, guaranteed electric cleaning brush 10's stability and practicality.
Referring to fig. 6 and 7, a cleaning brush 20 according to a second embodiment of the present invention includes a handle bar 21, a connecting member 22 connected to one end of the handle bar 21, a rolling brush 23 mounted on the connecting member 22, and two support plates 24 fixed to the connecting member 22. The connecting element 22 and the support plate 24 are located on the central axis of the hand lever 21, which central axis of the hand lever 21 can be referred to as a second central axis in this embodiment, and is denoted by the reference symbol y in fig. 5. The manner of the hand lever 21, the connecting member 22, the rolling brush 23, and the driving rolling brush 23 in this embodiment is the same as that in the first embodiment, and will not be described again.
Two identical holder plates 24 are arranged in parallel face-to-face, and the holder plate 24 has a restricting portion 241 and a fixing portion 242, and the restricting portion 241 and the fixing portion 242 are connected by an elastic member 243 to form the holder plate 24. The restricting parts 241 of the two holder plates 24 are symmetrically disposed at both sides of the roll brush 23, and the fixing parts 242 of the two holder plates 24 are symmetrically fixed at both sides of the connecting member 22. The outer contour of the fixing portion 242 includes a rectangular configuration and a semicircular configuration connected to one end of the short side of the rectangular configuration, the outer contour of the limiting portion 241 has an arc portion which can contact with the surface to be cleaned, the arc portion is 1/2 semicircular configuration, and the limiting portion 241 limits the amount of deformation of the rolling brush 23 which is recessed in the radial direction under the action of external force. In the rolling direction, the projection of the limiting portion 241 is located in the end surface of the rolling brush 23, the projection of the limiting portion 241 forms a second line in the end surface of the rolling brush 23, and the axis of the second line is intersected with and perpendicular to the second central axis y of the hand lever 21. In this embodiment, the elastic member 243 is a spring.
In this embodiment, the connection manner of the rolling brush 23 and the connecting member 22 may be: the roller brush 23 is rotatably fixed to a holder (not shown), and one end of the holder is fixedly provided to the link 22. Specifically, the roller is fixed on a clamping member, one end of the clamping member is fixedly arranged on the connecting member 22, the two support plates 24 are symmetrically fixed on two sides of the connecting member 22, and the limiting portions 241 of the two support plates 24 are located on the outer sides of two end faces of the rolling brush 23.
The effective working length of the bristles of the electric cleaning brush 20 is the distance from the part of the brush layer contacted with the cleaned surface to the second line in the direction vertical to the cleaned surface, and the change of the position of the second line drives the change of the effective working length of the bristles. When the electric cleaning brush 20 is in contact with the surface to be cleaned and pressure is applied to the electric cleaning brush 20, the limiting portion 241 moves relative to the roller brush 23 under the action of the surface to be cleaned, and the moving direction is the same as the direction of the central axis of the hand lever 21, i.e., the second central axis y. Specifically, when no pressure is applied to the electric cleaning brush 20, the spring is in an original state, when pressure is applied to the electric cleaning brush 20, the rolling brush 23 is extruded and deformed under the action of the cleaned surface, the limiting portion 241 is in contact with the cleaned surface, and under the action of the cleaned surface, the spring is compressed and deformed to drive the limiting portion 241 to move relative to the rolling brush 23, the projection of the limiting portion 241 moves in the direction of the second central axis y of the hand lever 21, the position of the second line is changed, and therefore the effective working length of bristles of the electric cleaning brush 20 is changed. When the pressure applied to the electric cleaning brush 20 is different, the spring is compressed and deformed differently, the projection of the limiting part 241 moves at different distances in the direction of the second central axis y of the hand lever 21, and the position of the second line is changed differently, so that different effective working lengths of the bristles are generated.
The effective working length of the bristles of the electric cleaning brush 20 shown in this embodiment can be changed according to the change of the pressure applied to the electric cleaning brush 20, thereby changing the frictional force generated when the electric cleaning brush 20 is in contact with the surface to be cleaned. When the pressure applied to the electric cleaning brush 20 is too large, the limiting part 241 limits the deformation amount of the rolling brush 23 which is concave along the radial direction under the action of the external force, the effective working length of the brush hair is limited, and the electric cleaning brush 20 is contacted with the surface to be cleaned to generate smaller friction force and smaller kickback force. The effective working length of the bristles of the electric cleaning brush 20 can be changed according to actual requirements, so that the friction force generated by the contact between the electric cleaning brush 20 and a cleaned surface is changed, and the practicability and the usability of the electric cleaning brush 20 are improved.
The structure of the first and second embodiments in which the maximum effective working length of the bristles is adjustable can be applied not only to the manual cleaning brushes of the first and second embodiments, but also to ac and dc electric cleaning brushes.
To sum up, the utility model provides an electric cleaning brush 10, 20 can the automatic adjustment maximum effective working length of brush hair with this effect that reaches the frictional force of control brush hair and ground, effectively prevent electric cleaning brush 10, 20 from producing too big anti-power of kicking, satisfy the user and have less anti-demand of kicking power when using anti-rolling brush type electric cleaning brush 10, 20 cleaning, especially also can keep better stability when cleaning the coarse surface, even the pressure that electric cleaning brush 10, 20 hand lever lifted is too high or was exerted on electric cleaning brush 10, 20 is too big, electric cleaning brush 10, 20 can not produce great or too fast frictional force, anti-power of kicking or reverse walking stroke, promote electric cleaning brush 10, 20's ease for use, the clear efficiency has been increased.
