Description
Technical field:
The utility model relates to the ventilator technical field, more specifically to a kind of ventilator with motor protection device.
Background technique:
Existing most ventilator, their motor all are directly to be fixed on the inwall of Blower Housing, and the motor of these ventilators is directly exposed in the middle of the air fluidly; Because the difference of the working environment of ventilator, the pollution level of air also is different, compares serious environmental in some atmospheric pollution; Like places such as building site, workshops, because motor is directly exposed in the air, flowing along with air so; Airborne a lot of rubbish, pollutant can be attached to motor surface influence motor radiatings; Or directly get in the middle of the motor, influencing the normal operation of motor, this can have a strong impact on the working life of fan motor.
The model utility content:
The purpose of the utility model is exactly the deficiency to existing technology; And a kind of ventilator with motor protection device is provided; It can prolong the working life of fan motor so that motor has the more working environment of cleaning, and it can work under the environment of high temperature, humidity.
The technological solution of the utility model is following:
A kind of ventilator with motor protection device; Comprise motor, Blower Housing and impeller; Motor is fixed on the inwall of motor host cavity, and sidewall and impeller that the main shaft of said motor passes the motor host cavity be fixed together, and said motor host cavity is fixed on the inwall of Blower Housing; The sidewall that one end of ventilation duct connects on the motor host cavity, the other end passes Blower Housing, and the outer wall of this ventilation duct and the contacted part of Blower Housing and Blower Housing are fixed together.
Be fixed with block on the main shaft of said motor, and form thread section on the said main shaft, said thread section sleeve is in the center hole of mounting disc of lobus sinister sheet and the mounting disc of lobus dexter sheet; Mainshaft nut is screwed onto on the thread section; And this mainshaft nut is pressed against on the end face of lobus dexter sheet mounting disc, and mounting disc of said lobus sinister sheet and the mounting disc of lobus dexter sheet form respectively that left convex tendon is accommodated nest and right convex tendon is accommodated nest, form convex tendon on the blade; This convex tendon is clamped in that left convex tendon is accommodated nest and right convex tendon is accommodated between the nest; Said right convex tendon is accommodated on the bottom surface of nest and is formed some wedge grooves, forms the wedge lug on the said convex tendon, and wedge lug sleeve is in the wedge groove; The adjusting bolt passes the mounting disc of lobus sinister sheet and lobus dexter sheet mounting disc nut is screwed onto together, and said blade is an aluminium alloy vane.
The bottom of said Blower Housing is welded with support, and the top of Blower Housing is welded with suspension ring.
Said motor host cavity is fixed on the connecting plate, and said connecting plate is fixed on the inwall of Blower Housing.
The beneficial effect of the utility model is: its motor is not directly exposed in the middle of the air; Therefore the working environment of its motor cleans more; This has just prolonged the working life of fan motor, and it can work under the environment of high temperature, humidity.

Embodiment:
Embodiment 1: see shown in Fig. 1 to 3; A kind of ventilator with motor protection device; Comprise motor 4, Blower Housing 1 and impeller 5; Motor 4 is fixed on the inwall of motor host cavity 2, and sidewall and impeller 5 that the main shaft of said motor 4 passes motor host cavity 2 be fixed together, and said motor host cavity 2 is fixed on the inwall of Blower Housing 1; The sidewall that one end of ventilation duct 3 connects on motor host cavity 2, the other end passes Blower Housing 1, and the outer wall of this ventilation duct 3 and Blower Housing 1 contacted part and Blower Housing 1 are fixed together.
The bottom of said Blower Housing 1 is welded with support 11, and the top of Blower Housing 1 is welded with suspension ring 12.
Said motor host cavity 2 is fixed on the connecting plate 21, and said connecting plate 21 is fixed on the inwall of Blower Housing 1.
Embodiment 2: see that Fig. 4 is to shown in Figure 6; Be fixed with block 411 on the main shaft 41 of said motor 4, and form thread section 412 on the said main shaft 41, said thread section 412 sleeves are in the center hole of lobus sinister sheet mounting disc 6 and lobus dexter sheet mounting disc 7; Mainshaft nut 413 is screwed onto on the thread section 412; And this mainshaft nut 413 is pressed against on the end face of lobus dexter sheet mounting disc 7, and said lobus sinister sheet mounting disc 6 and lobus dexter sheet mounting disc 7 form left convex tendon respectively and accommodate nest 61 and accommodate nest 71 with right convex tendon, form convex tendon 81 on the blade 8; This convex tendon 81 is clamped in that left convex tendon is accommodated nest 61 and right convex tendon is accommodated between the nest 71; Said right convex tendon is accommodated on the bottom surface of nest 71 and is formed some wedge grooves 711, forms wedge lug 811 on the said convex tendon 81, and wedge lug 811 sleeves are in wedge groove 711; Regulate bolt 9 and pass lobus sinister sheet mounting disc 6 and the mounting disc of lobus dexter sheet 7 and be screwed onto with nut, said blade 8 is an aluminium alloy vane.All the other are with embodiment 1.
