Problems solved by technology
Although this kind of setting can ensure that the tilting of the suction head can always reach one of the stop positions during the working process of the suction nozzle, when the user pulls the suction head back, the suction head is easy to move relative to the bottom frame. The front part of the front side is tilted, so that the suction port cannot be well attached to the ground to be cleaned, thus affecting the dust collection effect

Embodiment Construction
[0024] The present invention will be further described below in conjunction with accompanying drawing and embodiment:
[0025] Such as figure 1 The vacuum cleaner nozzle shown has a chassis 1 comprising a rear chassis part 2 with a roller 3 and a front part 4 protruding forwards in the suction direction. The suction head 5 is installed on the front part 4 of the chassis 1, and it can rotate around the first horizontal rotating shaft 6. The bottom surface of the suction head 5 is provided with a front edge 7 of the suction port and a rear edge 7 of the suction port. A pair of support wheels 3' are installed on the bottom of the back side of the suction head 5. The pair of support wheels 3' are located on the left and right sides of the roller 3. The support points of the support wheels 3' are far from the front of the suction port. The position of the suction port 8 defined by the edge 7 and the rear edge 7 ′ of the suction port is constant (usually the vertical distance H3 be...

The invention relates to a suction nozzle of a vacuum dust collector, which comprises an underframe, a suction head and a suction pipe connecting piece, wherein the underframe comprises a rear underframe part and a front side part positioned at the front side of the underframe in suction direction, and a roller is arranged at the rear end of the rear underframe part; the suction head is arranged on the front side part, can rotate around a first horizontal rotating shaft within a set rotating area, and a suction port is arranged on the bottom surface of the suction head and is limited by a suction port front edge and a suction port rear edge; the suction pipe connecting piece is arranged on the rear underframe part and can rotate around a second horizontal rotating shaft within a set rotating area; and a support wheel is arranged on the rear end of the suction head, and the position relationship between the supporting point of the support wheel and the suction port formed by the suction port front edge and the suction port rear edge is constant. During the working process of the suction nozzle, the suction port is attached to the ground to be cleaned constantly by means of the ground supporting role of the roller and / or the support wheel, so that the suction nozzle can obtain good dust collection efficiency; and the suction nozzle can be moved more easily due to the arrangementof the roller and the support wheel.
Description
technical field [0001] The invention relates to a suction nozzle of a vacuum cleaner. Background technique [0002] Publication No. CN101099648A discloses a "suction nozzle for floor vacuum cleaner", which has: a chassis, which includes a rear chassis part with at least one roller and protruding in the suction direction In order to connect the front part with the suction head; the suction head is mounted on the front part of the chassis so as to be capable of tilting movement around a horizontal tilting axis and has a front edge of the suction port on its bottom surface and the suction port defined by the rear edge of the suction port; and a suction pipe connector, which is arranged on the chassis so as to be rotatable within a fixed rotation range around the horizontal hinge axis. The forward tilting movement of the suction head around the horizontal tilting axis is limited by the first stop position of the suction head, and the backward tilting movement is limited by the ...
