Abstract

The utility model relates to a fan wheel device of a blast-typed fan. A ring wall center is provided with a central shaft; the bottom edge of a ring wall is outwards extended with a bottom plate which is provided with a plurality of vanes. The utility model is characterized in that a butting position between the bottom plate and the ring wall is encircled with an arc wall surface, so the flow of the gas is smoother.

Description

The Fan impeller device of blowing-type fan
Technical field
The utility model relates to a kind of Fan impeller device of blowing-type fan, and referring in particular to impeller has preferable and the Fan impeller device of the blowing-type fan that flows of propellant smoothly.
Background of invention
Please read shown in Figure 1, its a kind of traditional blowing-type fan structure, mainly central siphon 91 outer diameter parts by housing 90 are combined with stator 92, the inside diameter of central siphon 91 is with the central shaft 95 pivot joint rotations of bearing 93 for impeller 94, impeller 94 extends ring flat-plate 96 by ringwall 98 bottoms, it is radial and keep the blade 97 that stands vertically with ring flat-plate 96 that ring flat-plate 96 adjacent peripheral positions are provided with number, there is appropriate gap between this blade 97 and the ringwall 98, when impeller 94 is driven in rotation, air can be inhaled into by this gap digit, and gas is sent by an exhaust outlet by blade 97 drivings, the traditional blowing-type fan structure of this kind, it originates from blade 97 and rotate the suction that is caused in the swirl channel of housing 90, this gas is driven send mobile, therefore, whether this gas flow is smooth and easy has very big connection with air-supply effect this blowing-type fan, and the traditional blowing-type fan of this kind, forms vertical angle in this ringwall 98 and ring flat-plate 96 engagement positios, therefore, this gas that is inhaled into tends to accumulate in this vertical angle position and forms sinuous flow.
Please read shown in Figure 2, No. 388203 " Fan impeller device " patent of its claimant institute Shen Zhun Taiwan patent announcement, promptly improved this impeller 80 by establishing number axis streaming flabellum 82 and number blowing-type flabellum 83 around the ringwall 81 at this shortcoming, when this ringwall 81 rotates, this axial flow flabellum 82 along the axle center to driving air-flow, this blowing-type flabellum 83 then along the axle center vertically to driving air-flow.
Summary of the invention
The utility model purpose is to provide a kind of Fan impeller device of blowing-type fan, and this impeller can make the air-flow of driving that comparatively smooth gas flow path is arranged, and makes this blowing-type fan that preferable air-supply effect be arranged.
The utility model is to provide a kind of Fan impeller device of blowing-type fan, establish central shaft by a ringwall center, this ringwall base is outward extended with base plate, establishes the blade of plural number on the base plate, and it is characterized in that: the engagement positio of this base plate and ringwall is around being provided with the circular arc wall.
The utility model is also to provide this circular arc wall directly to be extended by ringwall and is connected to base plate, and forms smooth wind-guiding path.
The utility model is also to provide angle between this base plate and ringwall greater than 90 ° of angles.
The utility model makes gas flow more smooth and easy.

Embodiment
See also appended graphicly, the utility model lifted the following example explanation:
Please read shown in Figure 3, the utility model one preferred embodiment, this blowing-type fan is provided with vortex passage 11 by a shell block 1, establish one in this vortex passage 11 due to 12, stator 12 can articulate rotation for impeller 2, and shell block 1 is by a cover plate 13 cover caps, and cover plate 13 has wind inlet 14 breathable gas and from exhaust outlet 15 positions of shell block 1 one sides gas sent, to form a blowing-type fan.
Impeller 2 is established a central shaft 21 by the center of a ringwall 22, and this central shaft 21 can be articulated in stator 12 rotations of shell block 1, and ringwall 22 inwalls are provided with permanent magnet rings 23, and these ringwall 22 bottom side edge are outward extended with base plate 24, and the setting of going up of this base plate 24 has several blades 25.
Please read shown in Fig. 3,4, major character of the present utility model is 24 joints that become non-right angle of this ringwall 22 and base plate, this engagement positio is preferable around being set as circular arc wall 26, and this circular arc wall 26 can directly be extended and is connected to base plate 24 by ringwall 22, to form the wind-guiding path of fan in wind inlet 14 and 15 smoothnesses of exhaust outlet.
Please read Fig. 5 and shown in Figure 6 again, this base plate 24 can also form outwardly and being obliquely installed down, and the angle that makes 22 of this base plate 24 and ringwalls is greater than 90 angles, and so, this impeller institute gas driving has more smooth delivery.
The Fan impeller device of blowing-type fan of the present utility model, this driven gas can become the wind-guiding path of smoothness according to this ringwall with the circular arc wall between base plate, and when this base plate becomes outwardly, being obliquely installed down, when forming angle with ringwall greater than 90 ° of angles, this wind-guiding path can be more smooth.
The utility model can not depart under main spirit and the feature with other different forms enforcement.Therefore, above-mentioned preferred embodiment is just enumerated by way of example, and it should be considered as restriction of the present utility model.Scope of the present utility model is defined by claim, but not is defined by the content of specification.The variation or the modification that belong to the equivalence of claim all are to fall within scope in the utility model.

Claims (3)

1, a kind of Fan impeller device of blowing-type fan is established central shaft by a ringwall center, and this ringwall base is outward extended with base plate, establishes the blade of plural number on the base plate, and it is characterized in that: the engagement positio of this base plate and ringwall is around being provided with the circular arc wall.
2, according to the Fan impeller device of the described blowing-type fan of claim 1, it is characterized in that: this circular arc wall is connected to base plate by direct extension of ringwall, and forms smooth wind-guiding path.
