Abstract
The utility model discloses an air exhaust device used for a kitchen ventilator. The air exhaust device comprises an installation base and an installation fixing ring; multiple metal vanes are uniformly connected between the installation base and the installation fixing ring; the metal vanes do not stretch out of the installation base and the installation fixing ring; the metal vane are stretched to form an arc surface; a round lug boss which protrudes upwards is punched in the middle of the installation base; a hollow rotating shaft is connected to the middle of the round lug boss; the radius of the arc surface is equal to the radius of the installation fixing ring; as a technology which stretches and thins the vanes is adopted for the metal vanes, the height of the vanes is increased, a wind wheel is enabled to have the vanes at enough height when the gear number of the vanes is unchanged, and the air volume and the air pressure are increased. The air exhaust device used for the kitchen ventilator has the beneficial effects of being practical, light and convenient, and low in production cost and use cost, reducing the electric energy, achieving good stability, and being hard to loose and high in air suction volume.
Description
Technical field
The utility model relates to a kind of kitchen ventilator parts, particularly a kind of kitchen ventilator air exhausting device.
Background technique
In the kitchen of family, in order to get rid of oil smoke, kitchen ventilator all can be installed.Air exhausting device in existing kitchen ventilator, for more air exhaust blade is installed, generally all adopt a lot of blade support to install, conventionally have three above supporting elements, and self thickness of blade is thick, has caused existing kitchen ventilator heaviness, in working procedure, power consumption is large, and suction air volume is low, and it is convenient not to use.In addition, after kitchen ventilator service time is long, easily occur looseningly, affected working life of product.
In addition, the height of air exhaust blade is subject to the restriction of blade gear number, and when blade is increased, gear number will correspondingly reduce, for above-mentioned defect, and invention the utility model.
Model utility content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and a kind of novel kitchen ventilator air exhausting device is provided.
To achieve these goals, the measure that the utility model is taked:
A kind of kitchen ventilator air exhausting device, comprise mounting base and retainer ring is installed, between described mounting base and installation retainer ring, be connected with uniformly some metal blades, metal blade does not reach mounting base and installs outside retainer ring, metal blade stretches a cambered surface, in the middle of mounting base, punching press has a round boss raising up, and is connected with hollow rotating shaft in the middle of round boss;
The radius of described cambered surface equates with the radius that retainer ring is installed;
Described hollow rotating shaft end punching press has a circular junction surface, and hollow rotating shaft is connected on round boss by circular junction surface, offers some attachment holes on circular junction surface;
In described hollow rotating shaft, be provided with internal thread;
In the middle of described hollow rotating shaft, offer the pin-and-hole vertical with axle center and/or offer locating slot at the top of hollow rotating shaft;
The diameter of described circular junction surface is less than or equal to the diameter of round boss;
Described metal blade has adopted the technique that makes blade ironing, has increased the height of blade, makes wind wheel in the situation that not reducing blade gear number, has sufficiently high blade height, has increased air quantity and blast.
The beneficial effects of the utility model: practicality, light, to produce, user cost is low, saved electric energy, good stability, is difficult for looseningly, and suction air volume is large.
Brief description of the drawings
Fig. 1, structural representation of the present utility model.
Embodiment
A kind of kitchen ventilator air exhausting device, comprise mounting base 1 and retainer ring 2 is installed, between described mounting base 1 and installation retainer ring 2, be connected with uniformly some metal blades 3, metal blade 3 does not reach mounting base 1 and installs outside retainer ring 2, metal blade 3 stretches and has a cambered surface, in the middle of mounting base 1, punching press has a round boss raising up 4, in the middle of round boss 4, be connected with hollow rotating shaft 5, the utility model is connected to by hollow rotating shaft 5 on the motor power output shaft of kitchen ventilator, rotate with motor, metal blade 3 is in rotating, can the row's of playing wind action, oil smoke is discharged to outdoor in time simultaneously, 3 of metal blades adopt two fixed blocks to install, metal blade 3 stretches and makes, reduce the weight of whole model utility, light, in working procedure, power consumption is lower, save the energy.
The radius of described cambered surface with the radius of retainer ring 2 be installed equated, improved exhaust air rate, air draft effect is better.
Described hollow rotating shaft 5 end punching presses have a circular junction surface 6, and hollow rotating shaft 5 is connected on round boss 4 by circular junction surface 6, on circular junction surface 6, offers some attachment holes, are convenient to connect, and firmly, are difficult for loosening.
In described hollow rotating shaft 5, be provided with internal thread.
In the middle of described hollow rotating shaft 5, offers the pin-and-hole vertical with axle center and/or offer locating slot at the top of hollow rotating shaft 5, be convenient to being connected between motor output shaft, connects better firmly, scheme is various.
The diameter of described circular junction surface 6 is less than or equal to the diameter of round boss 4.
Described metal blade 3 has adopted the technique that makes blade ironing, has increased the height of blade, makes wind wheel in the situation that not reducing blade gear number, has sufficiently high blade height, has increased air quantity and blast.
In order to improve the efficiency of air draft, can also be set with an internal fan leaf at hollow rotating shaft 5.
