Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment: First, according to image 3 The vacuum cleaner of the illustrated embodiment is composed of a body 100 , an extension pipe 300 , a suction pipe 200 , and a suction port 400 . Wherein, the body 100 is used to collect the dust sucked by the suction force generated by the fan motor M; the suction pipe 200 and the extension pipe 300 move the dust into the body 100 under the suction force; and the suction port 400 is connected to the extension pipe 300, contact the surface to be cleaned.

[0027] A pair of wheels W are installed at the rear of the body 100. The wheels W are designed to be half the size of the body 100. Therefore, they have nothing to do with the shape of the floor of the cleaned surface and can move anywhere freely. Moreover, the bottom surface of the wheels W is made of rubber. or urethane material to cover to prevent slipping....

Abstract

An exhaust filter structure of vacuum cleaner is composed of an exhaust unit with exhaust hole on internal bottom, an exhaust filter with the exhaust ribs for attaching it to said exhaust hole and the lugs, and a casing attached to the exhaust filter via said lugs.

Description

technical field [0001] The invention relates to the field of vacuum cleaners. Background technique [0002] figure 1 As shown, a general vacuum cleaner is composed of a body 2, a connecting pipe 4, an extension pipe 6, and a suction nozzle 8. Wherein, a motor is installed inside the body 2 to generate suction force; the connecting pipe 4 connected to the inside of the body is made of soft material; the extension pipe 6 is connected to the connecting pipe 4, and its length can be adjusted at will; The nozzle 8 is coupled to the end of the extension pipe 6, and contacts the ground to suck dust. [0003] A fan motor (not shown in the last figure) is installed inside the body 2, and the fan motor is used to form a vacuum and generate suction force. and also, figure 2 As shown, in order to filter the dust contained in the air, the filter device is installed behind the inside of the body. In addition, a pair of wheels 2a are arranged on the lower side of the body 2, so that ...
