The utility model discloses set up helical arrangement's long blade and short blade at the impeller wheel face, wholly be "concave" style of calligraphy and the blade that differs in length, can effectively avoid the offend and the uneven condition of local pressure of air current, and then form stable air current, turbulent production can be avoided to stable air current, can also reduce the noise, promotes user experience.
Description
Technical Field
The utility model relates to a respiratory therapy equipment field, concretely relates to fan wheel for breathing machine, oxygenerator.
Background
The respiratory mucosa of the elderly gradually shrinks, the secretion function is reduced, the respiratory function is weakened, and the quantity of the inhaled and discharged gas in the body is correspondingly reduced, thereby influencing the exhaust of waste gas and the inhalation of fresh air. The ventilator is a medical instrument which can replace or assist the respiratory function of people, the oxygen generator is also an important matched medical device, the ventilation capacity of the lung is increased through a fan in the ventilator, the respiratory function is improved, the respiratory function consumption is reduced, fresh oxygen is provided for patients through the oxygen generator, the oxygen metabolism is improved, and continuous ventilation and breathing can be maintained when the patients stop breathing and lose the autonomous respiratory function, so that the continuation of metabolism and life is maintained.
The problems in the prior art mainly lie in that: blades on fan impellers of household ventilators and oxygenerators in the current market basically adopt a mode that through ribs are gradually opened, the impellers rotate at high speed, and after gas between adjacent blades is centrifugally accelerated, small vortex is formed at an air outlet of the blades of the impellers to generate pneumatic noise; the direction of the air inlet and the air outlet of the impeller is vertical, so that collision is formed, the supercharging efficiency is reduced, and the local pressure is uneven; the impeller has heavier mass, thereby reducing the acceleration performance of the fan and influencing the treatment effect of the respirator.
Disclosure of Invention
The utility model aims at overcoming the defects and deficiencies of the prior art and providing a fan impeller for a respirator and an oxygen generator, which has simple structure, low noise, fast acceleration and long service life.
In order to realize the above purpose, the technical proposal of the utility model is that: the utility model provides a fan wheel for breathing machine, oxygenerator, includes discoid impeller main part, impeller main part includes impeller wheel face and is located the copper sheathing of impeller wheel face center, its characterized in that: the impeller is characterized in that a plurality of groups of blade groups which are spirally arranged by taking the copper bush as the center are uniformly arranged on the wheel surface of the impeller, each blade group comprises a long blade and two short blades, and the long blade and the short blades are integrally lifted gradually from the wheel edge to the wheel center.
The arc length of the short blade is 0.5-0.85 times of that of the long blade.
The back of the impeller wheel face is provided with a plurality of reinforcing ribs, one ends of the reinforcing ribs are connected with the copper sleeve, and all the reinforcing ribs are symmetrically distributed by taking the copper sleeve as a center.
Compared with the prior art, the utility model, following advantage has:
1. the utility model discloses set up helical arrangement's long blade and short blade at the impeller wheel face, wholly raise and the blade that differs in length gradually to the wheel center by the wheel limit, can effectively avoid the condition that the offend and the local pressure of air current are uneven, and then form stable air current, the production of torrent can be avoided to stable air current, can also reduce the noise, promotes user experience.
2. The utility model arranges a plurality of strengthening ribs which are symmetrically distributed by taking the copper bush as the center on the back of the impeller wheel surface, on one hand, the mechanical strength of the impeller can be improved, and the service life of the impeller can be prolonged; on the other hand, stable support can be provided for the wheel surface, so that the impeller is accelerated more quickly.
Drawings
Fig. 1 is a first schematic structural diagram (perspective view) of the present invention.
Fig. 2 is a second schematic structural diagram (top view) of the present invention.
Fig. 3 is a third schematic structural diagram (bottom view) of the present invention.
In the figure: the impeller comprises an impeller main body 1, an impeller wheel surface 2, a copper sleeve 3, a blade group 4, a long blade 5, a short blade 6 and a reinforcing rib 7.
Detailed Description
The present invention will be described in further detail with reference to the following description and embodiments in conjunction with the accompanying drawings.
Referring to fig. 1-3, a fan wheel for breathing machine, oxygenerator, includes discoid impeller main part 1, impeller main part 1 includes impeller wheel face 2 and is located the copper sheathing 3 at impeller wheel face 2 center, the back of impeller wheel face 2 is provided with a plurality of strengthening ribs 7, the one end of strengthening rib 7 links together with copper sheathing 3, and all strengthening ribs 7 use copper sheathing 3 to be central symmetric distribution, evenly be provided with the multiunit on impeller wheel face 2 and use copper sheathing 3 to be the blade crowd 4 that the center is the spiral arrangement, blade crowd 4 includes a long blade 5 and two short blades 6, the arc length of short blade 6 is 0.5 ~ 0.85 times of long blade 5 arc length, long blade 5 and short blade 6 are whole to be raised gradually to the wheel center by the wheel limit, long blade 5 is because its curvature radius reduces gradually to the wheel center by the wheel limit for long blade 5 is close to the wheel center and up more.
