Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with drawings and the embodiments,
The present invention will be described in further detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention,
It is not intended to limit the present invention.
The present invention proposes first embodiment, as shown in Figure 1, a kind of air exhausting device 100, including outer housing 110 and fan group
Part 120, the fan component 120 include spiral case 121, motor 122 and impeller 123.Spiral case 121 is located at the inside of outer housing 110
And the inner surface integrated injection molding with outer housing 110, the inner surface formation wind chamber 1211 of spiral case 121 and outer housing, the electricity
Machine 122 and impeller 123 are respectively positioned in wind chamber 1211, and wherein motor 122 is fixed on the inner surface of outer housing 110 and is located at spiral case
121 center, impeller 123 are fixedly connected on motor 122.
The fan component of air exhausting device of the present invention becomes one with outer housing, constant in air exhausting device overall dimensions in this way
In the case where, air quantity and wind pressure can be improved in the size by increasing spiral case and impeller；On the other hand since the air exhausting device is reduced
Assembly and positioning process, therefore the problem of do not fastened there is no installation, it can reduce the resonance of fan component and outer housing, from
And achieve the purpose that reduce noise and vibration, increase the comfort of mask wearing.
Spiral case inner sidewall can be identical at a distance from vane edge, or spiral case inner sidewall is with a distance from vane edge
To be arranged along the involute of impeller direction of rotation, it is preferred that as shown in Fig. 2, 121 inner sidewall of spiral case is from impeller in the present embodiment
The distance at 123 edges is gradually opening along 123 direction of rotation of impeller (direction of rotation that the arrow in figure on air duct is impeller 123)
Line setting, i.e., the inner sidewall of spiral case 121 is increasing with a distance from 123 edge of impeller, to keep the width in air duct increasing.
Air duct in the present embodiment is the cavity that its edge and 121 inner wall of spiral case are formed when impeller 123 rotates.The direction of rotation of impeller
When consistent with the direction that air duct broadens, in the case where identical impeller power, the air duct of involute setting can by compressed air
To obtain bigger air output, it ensure that user's air-breathing is smooth, inspiratory capacity is sufficient.
For the structure of motor, as shown in figure 3, the motor 122 includes stator module 1221, rotating assembly 1222, electricity
Road plate 1223.Wherein rotating assembly 1222 are assembled by bearing positioning and the cooperation of stator module 1221；Circuit board 1223 is located at
The bottom of motor 122 and the center for being welded in spiral case 121.Motor 122 operates after energization, so that impeller 123 rotates.
Further, motor further includes magnet steel, and usual magnet steel is located at the end face of rotating assembly, in the present embodiment, such as Fig. 4 institute

Diameter, less than the outer diameter of impeller 123.In the present embodiment, the diameter of air intake vent 113 is slightly larger than the internal diameter of impeller 123, can be better
Air inlet, and it is conducive to the better active air draught of impeller 123, increase air quantity.Preferably, the diameter of air intake vent 113 is than in impeller 123
Diameter can be 0.3 to 3 millimeter big.
For the connection type of procapsid 111 and back casing 112, the present invention proposes a specific embodiment, such as Fig. 7, Fig. 8 institute
Show, the internal edge of procapsid 111 is provided with side plate 1111, is provided on the internal edge of back casing 112 and 1111 phase of side plate
When the flange 1121 of cooperation, procapsid 111 and back casing 112 are installed, the back casing flange is just stuck in front case side
The inside of plate.The preliminary installation of procapsid and back casing can be achieved in this way.
Further, there are four clip-connecting rod 1112(wherein two for scattering device on the inner sidewall of 111 epipleural 1111 of procapsid
Do not marked in a clip-connecting rod figure), the lateral wall of 112 upper flange 1121 of back casing is provided with the clamping matched with clip-connecting rod 1112
Hole 1122.After procapsid 111 and back casing 112 are tentatively installed by side plate 1111 and flange 1121, by clip-connecting rod 1112
After being fastened on the blocked hole 1122 matched with its position shape, upper housing 111 and lower case 112 can be made to be more firmly mounted,
And this installs no screw, can fall off to avoid screw and generate harm to people, effectively improve safety.In the present embodiment, card
There are many forms for connecing hole and clip-connecting rod, can be that clip-connecting rod " 7 " type, "T"-shaped, inverted triangle taper etc. are a variety of to be clamped
Shape.
