Ground brush for vacuum cleaner and vacuum cleaner with the same

Abstract

A ground brush for a vacuum cleaner includes a ground brush body, a brushroll cover, a brushroll assembly and a microswitch. The brushroll cover is disposed on the ground brush body in such a manner that the brushroll cover can be opened and closed, and provided with a triggering part, wherein the brushroll cover and the ground brush body define a mounting space therebetween. The brushroll assembly is disposed in the mounting space and provided with a control circuit. The microswitch is disposed on the ground brush body, wherein the triggering part triggers the microswitch to turn on the control circuit when the brushroll cover is closed on the ground brush body, and the triggering part releases a trigger action on the microswitch to turn off the control circuit when the brushroll cover is opened.

What is claimed is: 
     
         1 . A ground brush for a vacuum cleaner, comprising:
 a ground brush body;   a brushroll cover disposed on the ground brush body in such a manner that the brushroll cover can be opened and closed, wherein the brushroll cover and the ground brush body define a mounting space therebetween, and the brushroll cover is provided with a triggering part;   a brushroll assembly disposed in the mounting space and provided with a control circuit; and   a microswitch disposed on the ground brush body, wherein the triggering part triggers the microswitch to turn on a control circuit when the brushroll cover is closed on the ground brush body, and the triggering part releases a trigger action on the microswitch to turn off the control circuit when the brushroll cover is opened.   
     
     
         2 . The ground brush according to  claim 1 , wherein the brushroll cover comprises:
 a cover body cooperating with the ground brush body to form the mounting space; and   a connecting part connected between the cover body and the ground brush body to make the cover body connected to the ground brush body,   wherein the triggering part is disposed on any one of the cover body and the connecting part.   
     
     
         3 . The ground brush according to  claim 2 , wherein the connecting part comprises a rotating shaft, the cover body is rotatingly closed on the ground brush body through the rotating shaft, the triggering part is disposed on the rotating shaft, and the rotating shaft rotates to make the triggering part trigger the microswitch when the cover body is closed. 
     
     
         4 . The ground brush according to  claim 2 , wherein the connecting part comprises a rotating shaft, the cover body is rotatingly closed on the ground brush body through the rotating shaft, the triggering part is disposed on the brushroll cover, and the triggering part triggers the microswitch when the brushroll cover is closed. 
     
     
         5 . The ground brush according to  claim 2 , wherein the connecting part comprises at least one of a snapping member and an inserting member, through which the brushroll cover is connected to the ground brush body, and the triggering part is disposed on the cover body. 
     
     
         6 . The ground brush according to  claim 1 , wherein when the brushroll cover is closed on the ground brush body, the triggering part directly contacts and triggers the microswitch. 
     
     
         7 . The ground brush according to  claim 1 , wherein the microswitch comprises:
 a fixing member fixed to the ground brush body and coupled with the control circuit;   a resilient member disposed on the fixing member; and   a button disposed on the fixing member and located between the resilient member and the fixing member, wherein the triggering part can turn on the control circuit if the resilient member presses the button, and when the triggering part is separated from the resilient member, the button returns to turn off the control circuit.   
     
     
         8 . The ground brush according to  claim 7 , wherein the resilient member is configured as an L-shaped resilient sheet. 
     
     
         9 . The ground brush according to  claim 1 , further comprising:
 a driving member disposed on the ground brush body and cooperating with the microswitch, wherein when the brushroll cover is closed on the ground brush body, the triggering part triggers the driving member and then triggers the microswitch indirectly through the driving member.   
     
     
         10 . A vacuum cleaner comprising the ground brush according to  claim 1 .
