Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
Please refer to fig. 1-6. It should be understood that the structure, ratio, size and the like shown in the drawings attached to the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any structure modification, ratio relationship change or size adjustment should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the function that the present invention can produce and the purpose that the present invention can achieve. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.
Referring to fig. 1-6, a safety device for a floor brush assembly of a dust collector, wherein a switch 1 is arranged on a body 6 of the safety device, a first rotating shaft is arranged on the body, a torsion spring is rotatably supported on the first rotating shaft, one end of the torsion spring is abutted against the body, a safety bracket 2 is fixed at the other end of the torsion spring, the safety bracket is provided with an abutting part facing a button of the switch, and a travelling wheel 3 facing the ground is arranged; when the dust collector floor brush assembly is contacted with the ground, the contact part of the safety support is contacted with the button 5 of the switch, and the travelling wheel is contacted with the ground; when the dust collector floor brush assembly is not in contact with the ground, the contact part of the safety support is not in contact with the button of the switch. Still rotate on the body and be equipped with a safe kicking block 4, this safe kicking block has a free end, and when dust catcher scrubbing brush subassembly and ground contactless, under the conflict portion of emergency support and the button of switch contactless state, the free end with the emergency support is contradicted and is set up.
The preferred embodiment is: the switch is connected in series in a circuit of the dust collector brush assembly and is a point contact type normally open switch.
After the electric floor brush leaves the cleaned surface for a certain distance, the safety switch cuts off the power supply under the action of the torsion spring and the self weight of the safety device, and when the electric floor brush is contacted with the cleaned surface, the safety bracket is forced to rotate and rotate to be pressed into the floor brush under the action of the gravity of the floor brush, so that the safety switch is forced to be switched on, and the rolling brush enters a rotating working state.
