Background technique
Ventilation fan is as a kind of circulation device for air that is usually used in the indoor air discharge, owing to use frequently, a large amount of pollutants must be adsorbed in the ventilation fan in the air, must often ventilation fan be cleared up and safeguard.As the patent No. is 200520012865.6 disclosed easy-to-dismount ventilation fans, and panel has only the panel can be for convenience detach in the fixed groove of jump ring grab on support; But motor, wind wheel in the ventilation fan equally also need frequent cleaning, maintenance, parts such as the motor in the ventilation fan that tradition is used, air channel cover plate are fixedly connected by screw, fix with screw and need the special tool dismounting, cleaning, inconvenient maintenance, and screw is lost easily, connection part such as fitting seat, screw thread is fragile, and working life is short; The ventilation fan motor internal adopts wire connecting power, if will take out motor palpus dismounting lead, there is potential safety hazard in dismounting inconvenience when cleaning, maintenance.
Summary of the invention
The purpose of this utility model is to connect shortcomings such as complicated, dismounting inconvenience in order to solve in the prior art parts in the ventilation fan, provides a kind of simple in structure, installs firmly, and is convenient to dismantle the ventilation fan of the fast quick-detach of cleaning, maintenance.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of ventilation fan of fast quick-detach, the spiral case top is equipped with motor in the chamber, wind wheel places in the spiral case lumen and through wing nut locking and connects motor, the air channel cover plate places the spiral case atrium, technical characteristics is that chamber, described spiral case top one sidewall is provided with a plurality of positioning keys, and the positioning key lower end is provided with limiting board; The top chamber sidewall relative with the sidewall that is provided with positioning key is provided with the elasticity fixture block; The top is equipped with the multiple tracks top board on the other two side, chamber, one side of motor flange is provided with the multiple tracks bayonet socket, multiple tracks bayonet socket and positioning key plug together and one side of motor flange spacing by limiting board, the one side and elasticity fixture block buckle relative on one side with the motor flange that is provided with the multiple tracks bayonet socket, the both sides in addition of motor flange are held out against by top board; The side of described air channel cover plate cooperates chucking with spiral case atrium inwall elasticity fixture block.
The power supply of described motor connects employing plug groove and connects.
The utility model utilizes the bayonet arrangement that positioning key, limiting board, elasticity fixture block, top board cooperate with motor flange and the elasticity fixture block cooperates with the air channel cover plate, with motor and air channel cover plate quick mounting in the ventilation fan spiral case, motor and spiral case adopt the plug groove to connect power supply, install, convenient disassembly is quick, install firm, be convenient to cleaning, maintenance, the installation of ventilation fan inner piece need not screw and fixes, stopped the installation question that conventional mounting seat thread failure, screw become flexible or come off and cause, guarantee the safe in utilization of ventilation fan, prolonged working life.
