The specific embodiment
In order further to understand content of the present invention, characteristics and effect, exemplify following examples now:
Describe each embodiment of the present invention in detail with reference to Fig. 3 to Fig. 5.
At first, Fig. 3 and Fig. 4 illustrate cleaner dust collecting device of the present invention simply.
Both, cleaner dust collecting device of the present invention was that the suction production part of by dust-absorbing element (110), dirt separation portion (130), dust-collecting box (140), directly tying in dust-absorbing element (110) and dirt separation portion (130) (150) constitutes.
The diameter of the dust-absorbing element of cleaner dust collecting device (110) is a cylindrical shape than highly big top, and the bottom is more down narrow more taper shape.
Certainly, the integral body of dust-absorbing element (110) also can be conical shape.
Discharge the dirt outlet (111) of dirt when meanwhile, being connected with the suction line (120) that sucks extraneous air on the outer peripheral face of dust-absorbing element (110) in addition.
Suction line (120) tangential direction to face on the outer peripheral face of dust-absorbing element (110) connects.And it is on the corresponding mutually position of benchmark that suction line (120) and dirt outlet (111) are positioned at dust-absorbing element (110) center separately.
At this moment, dirt outlet (111) forms to outer peripheral face one side of short transverse cutting dust-absorbing element (110).
And, be opening shape with the corresponding position of dirt outlet (111) when dust-collecting box (140) wraps the outer peripheral face of dust-absorbing element (110).Therefore, dust-collecting box (140) successfully gathers the dirt of discharging by dirt outlet (111).
The bore of above-mentioned dirt outlet (111) is 2/10~5/10 of above-mentioned dust-absorbing element (110) diameter substantially.
And the dirt separation portion (130) that constitutes cleaner dust collecting device is the cylinder filter that possesses the hollow of certain internal diameter, and is installed in dust-absorbing element (110) inboard.
And the center of dirt separation portion (130) follows the center of dust-absorbing element (110) on same axis, and meanwhile the inside of dirt separation portion (130) hollow is communicated with suction production part (150).
Both, there was the blast pipe function of discharging air the inner space of dirt separation portion (130).
The height of dirt separation portion (130) is identical with the height of dust-absorbing element (110), and meanwhile the inside of the hollow of dirt separation portion (130) is connected on the suction production part (150).
But, be not that the height of dirt separation portion (130) necessarily follows the height of dust-absorbing element (110) the same.As shown in Figure 5, the height of dirt separation portion (130) can be lower than the height of dust-absorbing element (110).
At this moment, the inboard top, hollow part of dirt separation portion (130) connects with suction production part (150) through dust-absorbing element (110).
The reception and registration area of the big more suction of diameter of dirt separation portion (130) is big more, can reduce the pressure loss.But in order successfully to isolate air and dirt, the diameter of dust-absorbing element (110) should be 1.6~1.75 times of dirt separation portion (130) diameter.
The diameter of dirt separation portion (130) inner space can reduce the pressure loss more near the external diameter of dirt separation portion (130) more.Dirt separation portion (130) internal diameter should be 6/10~8/10 of dirt separation portion (a 130) external diameter.
The suction production part (150) that constitutes cleaner dust collecting device is by the shell that is connected dirt separation portion (151), is installed in the fan (152) in the shell (151), drive motors (153) formation of drive fan.
At this moment, suction production part (150) connects the upside or the downside of dust-absorbing element (110) and dirt separation portion (130).
Meanwhile, constituting the position that the shell (151) of suction production part (150) is connected with dirt separation portion (130) all seals except the position of connection.
The present invention's formation minimizes suction and passes on stream, thus can prevent that suction from losing in stream, and from the air that makes full use of centrifugal force, successfully isolate dirt.
The running of cleaner dust collecting device of the present invention is described according to sequence of operations.
At first, drive suction production part (150), the extraneous air that contains dirt is drawn in the dust-absorbing element (130) by suction line (120).
In this process, the air that contains dirt passes through the tangential direction inflow of the suction line (120) of dust-absorbing element (110) to dust-absorbing element (130).
Afterwards, air and dirt are owing to they varies in weight, so be subjected to different centrifugal force.Separation of air and dirt thus.
Both, the dirt of phase counterweight was subjected to centrifugal force and circles round and flow downward along the madial wall of dust-absorbing element (110), and entered into dust-collecting box (140) lining by outlet (111).Almost there is not the air of weight to arrange in the space that suction production part (150) are arranged by dirt separation portion (130).
At this moment, do not have stream between the position of connection dirt outlet (111) and dust-collecting box (140), therefore can prevent the pressure loss and the noise that cause by stream to greatest extent.
And dirt separation portion (130) is that cylinder filter by hollow forms in the said process.Therefore dirt separates and stays the inside of dust-absorbing element (110) once more from air.
Therefore, only clean air is arranged to suction production part (150) lining, so can prevent dirt damage suction production part (150).
Particularly, suction production part (150) is connected in the dirt separation portion (130), so there is not stream between them.Therefore prevent the pressure loss and the noise that stream causes to greatest extent.
The dirt that circles round along the madial wall of dust-absorbing element (110) in the said process, both, be not able to do in time the dirt of discharging by outlet (111) and, from air, force isolated dirt by dirt separation portion (130).In circling round the way that descends, dust-absorbing element (110) madial wall is continuously introduced to dust-collecting box (140) lining by dirt outlet (111).This is because the position, outer peripheral face institute bonding part of dirt outlet (111) cutting dust-absorbing element (110) forms.
Particularly, the bore of dirt outlet (111) is 2/10~5/10 of dust-absorbing element (a 110) diameter, thus from air, successfully isolate dirt, and successfully discharge isolated dirt from air.
In the time of the diameter of dust-absorbing element (110) the chances are 154~160mm, the bore of outlet (111) the chances are 20~50mm.When being 42mm, the bore of outlet can obtain 85% the air and the separating property of dirt.So more successfully isolate airborne dirt.
At this moment experimental data such as table 1.
