Description
Technical field：
Blower equipment technical field is the utility model is related to, refers in particular to a kind of air blower with new and effective impeller.
Background technology：
Traditional blower wheel typically only has axle sleeve to add blade to form, and this structure is excessively simple, and length of blade is longer,
The torsion to be born during rotation is very big, along with blade and axle sleeve connection area are smaller, easily occurs leaf destruction in operation
Phenomena such as, when especially running into foreign matter and entering blower fan, blade is easily interrupted.In some occasions, to overcome above-mentioned phenomenon, some adds
Large shaft sleeve, length of blade is reduced, but so the overall weight of impeller increases, cost is high and power consumption is also big, unfavorable
In energy-conservation, furthermore, existing impeller operating efficiency is not also high.
Utility model content：
The purpose of this utility model is to overcome the weak point of existing product, there is provided a kind of new and effective leaf of air blower
Wheel.
The technical solution adopted in the utility model is：A kind of new and effective impeller of air blower, the impeller have one and opened
Central axle sleeve provided with keyway, the end outer wall of the central axle sleeve, which radially extends, forms radial direction round plate, radial direction disk
The surface in portion is uniformly provided with the reinforcement of eight connection central axle sleeve outer walls, in the surface of radial direction round plate, the outer end of reinforcement
Place forms first annular portion concentric with central axle sleeve, the outer end connection of the first annular portion and reinforcement, in radial direction disk
The surface in portion, also it is spaced formed with the second annular portion, the 3rd annular portion, and the first annular portion, in the outside of the first annular portion
Several hollow-out parts are formed between two annular portions, the 3rd annular portion；The outer wall of 3rd annular portion from both ends to center in it is prominent in justify
Sliding V-arrangement, has some blades, and the blade is divided into bent in the outside uniform intervals elongation moulding of the outer wall of the 3rd annular portion
The outer section of blade inner segment and blade, blade inner segment along central axle sleeve radial arrangement, the outer section of blade relative to blade inner segment bend 5 °~
10°。
The utility model impeller is integrally formed using die casting, simple production process, efficiency high, reasonable in design,
The weight of product, section are considerably reduced using reinforcement, engraved structure etc. on the basis of product bulk strength quality is ensured
About material；Moreover, blade and the joint face of main body are in round and smooth v-shaped structure, the increase of its connection area, bonding strength is stronger, can subtract
There is the phenomenon being broken in few blade, furthermore, fan efficiency can be improved using the blade of bent.
Brief description of the drawings：
Fig. 1 is the planar structure schematic diagram of the utility model impeller；
Fig. 2 is A-A sectional views in Fig. 1.
Embodiment：
The utility model is further illustrated with reference to specific embodiments and the drawings.
As Figure 1-Figure 2, described in the present embodiment it is a kind of new and effective impeller of air blower, the impeller has one
The central axle sleeve 1 of keyway 11 is offered, the end outer wall of the central axle sleeve 1, which radially extends, forms radial direction round plate 2, footpath
Thickness to round plate 2 is about the 1/6~1/5 of the axial length of central axle sleeve 1, and the surface of radial direction round plate 2 is uniformly provided with eight
The reinforcement 3 of the connection outer wall of central axle sleeve 1,3 curved structure of reinforcement, middle concave both ends are another with central axle sleeve 1 respectively
Hold level with both hands neat；The surface of radial direction round plate 2, reinforcement 3 outer end at form first annular portion 4 concentric with central axle sleeve 1,
First annular portion 4 is connected with the outer end of reinforcement 3, the surface of radial direction round plate 1, the outside of the first annular portion 4 also between
Every formed with the second annular portion 5, the 3rd annular portion 6, and formed between the first annular portion 4, the second annular portion 5, the 3rd annular portion 6
Several hollow-out parts 50；First annular portion 4, the second annular portion 5, the end of the 3rd annular portion 6 are somewhat higher than the end of central axle sleeve 1
Go out；The outer wall of 3rd annular portion 6 from both ends to center in it is prominent be in round and smooth V-arrangement, between the outer wall of the 3rd annular portion 6 is outside uniform
There are some blades 7 every elongation moulding, and the blade 7 is divided into blade inner segment 71 and the outer section 72 of blade, blade inner segment in bent
71 bend clockwise or counterclockwise along the radial arrangement of central axle sleeve 1, the outer section 72 of blade relative to the unified court of blade inner segment 71
5 °~10 °.By structures such as radial direction round plate 2, reinforcement 3, hollow-out parts 50, tried one's best on the basis of product structure intensity is ensured
Reduce its weight, save material and cost, while make in product that light outer weight, center of gravity are outer, rotary centrifugal force is outer, reduces rotation
Resistance, strengthen the operating efficiency of blade 7.
The utility model impeller is integrally formed using die casting, simple production process, efficiency high, reasonable in design,
The weight of product, section are considerably reduced using reinforcement, engraved structure etc. on the basis of product bulk strength quality is ensured
About material；Moreover, blade 7 and the joint face of main body are in round and smooth v-shaped structure, the increase of its connection area, bonding strength is stronger, can subtract
There is the phenomenon being broken in few blade, furthermore, fan efficiency can be improved using the blade 7 of bent.
