An air blower

Abstract

The present invention provides an air blower through which ejected air is free of dust and the like. The air blower (1) is provided with a main body (2) and a dedusting part (3). The main body comprises a main part (5) and a scroll air supplying part (7). A motor (4) is disposed in the main part. A centrifugal fan (6) is in-built in the air supplying part and a cylindrical ejecting port (24) is formed in the air supplying part. The dedusting part can be mounted on the main body in a removable manner. The main body and the dedusting part are arranged in an up-down manner. The dedusting part is mounted at the upstream side of the centrifugal fan. The motor is disposed in the main body in a manner that the rotating axis (4A) of the motor is longitudinal, and the ejecting port protrudes transversely from the periphery of the air supplying part, and therefore dust in the dedusting part at the upstream side of the centrifugal fan is removed, dedusted air is ejected from the ejecting port, and the ejecting position is not contaminated by dust or the like. The rotating axis of the motor is longitudinally arranged so that the overall air blower is longitudinally long, can be hung on shoulders through shoulder belts and can be easily used.

Description

technical field [0001] The present invention relates to a blower with a discharge port. Background technique [0002] Conventionally, as such blowers, the following knapsack blowers (for example, Patent Document 1), portable blowers (for example, Patent Document 2), and the like have been proposed. The knapsack blower has a back frame and a blower unit. The back frame has a back plate arranged along the back of the operator and a base portion extending rearward from the lower end of the back plate. The blower unit is The rear side of the back plate portion of the backpack frame is mounted on the base portion, and the fan, which is rotatably supported in the volute around the axis in the front-rear direction, is rotated by the power machine to blow out the air sucked from the suction opening. The volute has the suction opening for taking in external air at the front side. The portable blower has: a motor housing, the motor housing is built in the motor and protrudes to one ...

AI Technical Summary

Problems solved by technology

[0010] In the above-mentioned portable blower, the air sucked in from the suction port is blown out by the fan. Therefore, similar to the above-mentioned knapsack blower and the portable blower, there is the following problem: if the sucked air contains dust, sand, etc., Air containing dust, sand, etc. is ejected

[0011] In addition, in the above-mentioned portable blower, the air outlet is provided on the front upper part of the main body part, and the suction port is provided at the center part of the left side of the main body part in a different position and direction. When used as a blower or as a vacuum cleaner, it is necessary to change the direction of the main body, and there is a problem that it is inconvenient to use

[0012] In addition, in the blowers of the above-mentioned patent documents 1 to 3, the rotating shaft of the rotary driving member such as a motor is arranged laterally, and the fan is provided on the rotating shaft, so the motor part protrudes in the left and right direction like the patent document 2, for example, when hanging Inappropriate when used on the underarms or shoulders of the body
