Description

Suction inlet body of electric dust collector and electric dust collector with same Technical Field The invention relates to a suction inlet body of an electric dust collector and the electric dust collector with the suction inlet body. Background In a suction port body of a conventional electric vacuum cleaner, in order to improve a suction and dust removal function in a carpet (particularly, a carpet (carpet tile) having a long length of hair), a negative pressure is increased to improve adhesion to the carpet, and dust is sucked. In the case of the suction port body having such a structure, the suction port body has high adsorptivity to the carpet, and therefore mobility and operability on the carpet are reduced, which increases the burden on the user. Further, since the carpet is pressed against the bottom portion on the front end side in the suction port body, the bristles are covered on the back surface of the carpet (near the root portion of the bristles) and dust is present, and as a result, it is difficult to scrape the dust by the rotating brush in the suction port body. Japanese patent application laid-open No. 2017-184952 discloses an inhalation device configured to prevent adsorption of a soft cleaning object such as a carpet or a cotton quilt to a front portion of a bottom portion thereof by providing a plurality of adsorption preventing ribs at a front portion of an inhalation port in the bottom portion. In addition, in order to improve the dust sucking and removing function in carpets, japanese patent application laid-open No. 7-11734 discloses an inhalation device including a comb-shaped portion having a plurality of comb teeth. Disclosure of Invention In the case of the suction device of japanese patent application laid-open No. 2017-184952, the distance from the front end of the suction device to the suction port becomes longer by the front portion of the bottom portion for providing the suction prevention rib. Since the suction device of japanese patent application laid-open No. 7-11734 has a structure in which the comb portion protrudes outward from the distal end opening portion of the cylindrical nozzle, when cleaning the floor (floor), tatami, or the like, the distance between the floor or the wall and the suction port becomes longer by the comb portion. In view of the foregoing, the present invention provides a suction port body of an electric vacuum cleaner and an electric vacuum cleaner having the suction port body. According to one aspect of the present invention, there is provided a suction port body of an electric vacuum cleaner including a suction port body including a bottom portion facing a floor surface and a suction port provided at the bottom portion, the suction port body being capable of sucking dust on the floor surface from the suction port while moving in a front-rear direction along the floor surface, the suction port body of the electric vacuum cleaner characterized in that: A comb-tooth portion having a plurality of teeth is provided, as viewed from the bottom side, and protrudes rearward from a front position of the suction port such that the comb-tooth portion overlaps the suction port. Further, according to an aspect of the present invention, there is provided an electric vacuum cleaner including a cleaner body that sucks dust and collects the dust, and the suction port body is connected directly to the cleaner body or via an extension pipe. According to one aspect of the present invention, a suction port body of a small-sized electric vacuum cleaner having excellent operability on a carpet can be provided.
