Abstract
The utility model relates to a dual-purpose blower fan, and especially relates to an electric foot-operated and dual-purpose blower fan for two people to conduct civil air defense. The electric foot-operated and dual-purpose blower fan for two people comprises a support bench, a gearbox and a blower fan. The support bench is provided with the gearbox. The gearbox is fixedly connected to impellers in the blower fan through short shafts. One end of the blower fan is communicated with an air inlet, and the other end is provided with an air outlet. The gearbox is driven by a drive unit. The electric foot-operated and dual-purpose blower fan for two people has a simple structure and convenient operation, and increases safety performance.
Description
Technical field
The utility model patent relates to a kind of Dual-purpose fan, relates in particular to a kind of two human electric pedal Dual-purpose fans, is used for the people's air defense field.
Background technique
Present blower fan of the prior art all is DYN dynamic, and complex structure, and using effect is relatively poor relatively.
Chinese patent CN200520064840.0 discloses a kind of streamlined axial-flow blower, comprises air intake tube, main wind tube and wind outlet barrel; In said main wind tube, be provided with the motor fixed cover, the fixed cover in motor and the main wind tube is slidingly matched, and tightens up with pressing plate; Be connected with moving vane on this motor output shaft, the center portion is provided with guide ring in said air intake tube, this guide ring and air intake tube Joint; In said wind outlet barrel, being provided with sub warhead, is the cylinder bodily form at the shell shape of wind outlet barrel.This complex structure, and inconvenient operation.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the existing technology, provides a kind of simple in structure, and two easy to operate human electric pedal Dual-purpose fans.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of two human electric pedal Dual-purpose fans; Comprise trestle table, gearbox and blower fan; Described trestle table is provided with gearbox, and described gearbox is fixedly connected through the impeller in minor axis and the blower fan, and the end in the described blower fan is communicated with intake grill; Be provided with exhaust outlet in the other end of described blower fan, described gearbox drives through drive unit mutually.
At ordinary times when basement has power supply, starting electrical machinery, the motor driving drive plate is through driving to driven disc; The driven disc driving electric energy is to gearbox, and the gear in the gearbox passes to minor axis with kinetic energy again with axle, and minor axis drives the impeller in the blower fan, makes it rotation; Impeller produces new wind through the intake grill air intake, and new wind is fed to civil air defense works inside, wartime through exhaust outlet; When basement did not have power supply, the people was sitting on the seat cushion, the people hand steered hold up on the handle fixing from appearance, when people's pin is stepped on and forwarded to when foot-operated; Foot treadle passes to minor axis with kinetic energy through major axis, and minor axis drives the impeller in the blower fan, makes it rotation; Impeller produces new wind through the intake grill air intake, and new wind is fed to civil air defense works inside through exhaust outlet.
As preferably; Described drive unit comprises motor, belt, drive plate and driven disc, and described motor is located in the trestle table, and the end of described motor is provided with drive plate; Described driven disc and gearbox are fixedly connected, and described driven disc passes through belt transmission mutually with drive plate;
Or; Described drive unit comprises flywheel, blockchain, chain wheel and foot-operated, and described flywheel fixes through major axis and gearbox, and described chain wheel is fixed on the trestle table; Be with blockchain between described chain wheel and flywheel, described riding fixes through axis and chain wheel.
As preferably, described trestle table is provided with holds up handle, and the described handle of holding up is located at foot-operated the place ahead.
The utility model provides a kind of two human electric pedal Dual-purpose fans, and is simple in structure, easy to operate, improving safety.
