Problems solved by technology

However, according to this conventional example, the number of parts increases
Moreover, if it is provided only on one side, not only will the display area be reduced to reduce visibility, but also it will become an asymmetrical design biased to one side, which may reduce the designability.

Abstract

The present invention provides a suction port body of a large-scale display device, which has excellent visibility and excellent appearance design, and also provides an electric dust collector with the suction port body. A free connection part (500) comprises a tubular lower arm (560) and a tubular upper arm (580). The lower arm connects one end in the length direction with a suction port body (510) rotatably through a first rotation shaft part, and the other end is rotatably connected with one end of the upper arm through a second rotation shaft part. The first rotation shaft part and the second rotation shaft part are provided with one member selected from a horizontal rotation shaft and a vertical rotation shaft which is orthogonal with the horizontal rotation shaft, wherein the horizontal rotation shaft is configured parallelly with the length direction of the suction port body. The lower arm or the upper arm which rotates through the horizontal rotation shaft relatively to suction port body is provided with the following components: a housing component which communicates without air leakage; and a display substrate which is configured between a cover component that covers the outside of the housing component and the housing component and is provided with a light source part, and the cover component is provided with a light guiding part which diffuses the light from the light source part.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner and its nozzle body, and relates to a suction nozzle body provided with a display device for displaying an operating state and an operation mode, and an electric vacuum cleaner using the same. Background technique [0002] The current mainstream electric vacuum cleaner has a so-called canister type structure in which a vacuum cleaner body equipped with a dust collecting device and a floor suction nozzle body that sucks dust from the floor surface are connected by a suction pipe or a suction hose. The vacuum cleaner body of this conventional example is equipped with a dust collecting device and a blower device inside, and can move freely by wheels. On the other hand, the floor surface suction body is equipped with a rotary cleaning body and its drive unit in order to clean the floor surface, and by rotating the rotary cleaning body, the dust on the floor surface is fiddled and sucked. And this...
