Abstract

The present invention discloses a blower comprising: a snail-shaped base, a snail-shaped cover, blades and a motor, wherein the snail-shaped base and the snail-shaped cover form a exhaust channel, the blades are horizontally provided in the exhaust channel, the snail-shaped cover above the blades is provided with an air intake channel formed by a motor mounting chamber and a motor cover, and the motor is vertically disposed in the air intake channel and connected to the blades therebelow. The blower according to the present invention is structurally scientific and concise; the blades are horizontally disposed; the motor is vertically disposed above the blades in the air intake channel so that, on the one hand, when the blower operates, air is taken in and meanwhile provides effective heat dissipation for the motor, and on the other hand, there is a sufficient distance between the motor and the ground surface, and waterproof designs of the sealed capacitor junction box and both ends of the motor can perform an excellent waterproof function and avoid dangers from submergence of water. The blower according to the present invention is novelly designed, energy-saving, environment-friendly, safe for use, stable in placement and operations and long-service life.
