CN-121987086-A - Electric dust collector and suction inlet body

Abstract

The invention provides an electric dust collector and a suction inlet body, which can stably hold a rotary cleaning body and have less restriction on layout. The suction port body has a motor (11) as a drive source, a rotary cleaning element (12), a transmission unit (13), a fixed member (124) as a first magnetic body, and a second magnetic body (133). The transmission unit (13) is disposed coaxially with the rotary cleaning element (12), and transmits the power of the motor (11) to the rotary cleaning element (12) to rotate the rotary cleaning element (12). The fixed member (124) is disposed on the rotary cleaning body (12). The second magnetic body (133) is used for keeping the rotary cleaning body (12) at a prescribed position relative to the transmission part (13) through magnetic force acting between the second magnetic body and the fixed part (124).

Description

Electric dust collector and suction inlet body Technical Field Embodiments of the present invention relate to an electric vacuum cleaner including a rotary cleaning body and a suction port body. Background Conventionally, a rotary cleaning element used in an electric vacuum cleaner has an end portion held by sandwiching a case and a cover in a direction intersecting an axial direction. In this structure, the cover needs to be in contact with the rotary cleaning element, and therefore, there is a large restriction in layout. In addition, for example, when the locking shapes provided in the rotary cleaning element and the bearing portion are engaged with each other and held, stability of the mounting load is poor due to forming variation of the locking shapes, abrasion caused by repeated attachment and detachment, or the like. Patent document 1 Japanese patent No. 5241458 Disclosure of Invention The invention provides an electric dust collector and a suction inlet body which can stably hold a rotary cleaning body and have less restriction on layout. The electric vacuum cleaner of the embodiment is an electric vacuum cleaner provided with a suction port body. The suction port body has a drive source, a rotary cleaning body, a transmission unit, a first magnetic body, and a second magnetic body. The transmission unit is disposed coaxially with the rotary cleaning element, and transmits power from the drive source to the rotary cleaning element to rotate the rotary cleaning element. The first magnetic body is disposed on the rotary cleaning body. The second magnetic body is used for keeping the rotary cleaning body at a prescribed position relative to the transmission part by magnetic force acting between the second magnetic body and the first magnetic body. According to the electric vacuum cleaner and the suction inlet body of the invention, the rotary cleaning body can be stably held, and the restriction of layout can be reduced.
