Abstract
A cyclone separator for cleaner has a cyclone barrel body, which has an airflow inlet, an airflow outlet, an internal cyclone separating chamber, and a dust barrier umbrella at the upstream of airflow outlet in said cyclone separating chamber for separating the clean air and fine dust. Said clean air is directly exhausted. Said fine dust is mixed with the air in external layer for further cyclone separation.
Description
Technical field
The present invention relates to a kind of cyclone system for vacuum cleaner to use.
Background technology
Cyclone system for vacuum cleaner to use of the prior art as shown in Figure 3 comprises Whirlwind barrel (1), and this Whirlwind barrel (1) is provided with air flow inlet (11) and air stream outlet (12), and the inner chamber of described Whirlwind barrel (1) forms cyclone separating chamber (3).Outer eddy flow produces local eddy currents to the air stream outlet wraparound time, the grit that cyclonic separation is got off is rolled again, and particularly fine dusts stirs, thereby is taken away by ascending air.Secondly, outer gas flow also can enter dust storage chamber simultaneously, returns the easy and outer gas flow generation interference of cone from the centre, influences separating effect.
Summary of the invention
The object of the present invention is to provide a kind ofly at the indoor cyclone system for vacuum cleaner to use of setting up the dust-break umbrella of cyclonic separation, this cyclone separator can prevent effectively that the ascending air of wraparound from carrying fine dust secretly and directly discharging.
In order to reach above purpose, the scheme that the present invention adopts is: a kind of cyclone system for vacuum cleaner to use, comprise Whirlwind barrel, this Whirlwind barrel is provided with air flow inlet and air stream outlet, the inner chamber of described Whirlwind barrel forms cyclone separating chamber, the indoor dust-break umbrella that also is provided with of described cyclonic separation, described dust-break umbrella are positioned at the upstream of described air stream outlet and face toward described air stream outlet.
The diameter of the outer circumferential edges of described dust-break umbrella is being positioned at the cylinder internal diameter that is in same plane with described dust-break umbrella greater than the bore of described air stream outlet less than described Whirlwind barrel.
To be described Whirlwind barrel be positioned at 0.6～0.85 times of cylinder internal diameter that is in same plane with described dust-break umbrella to the diameter of the outer circumferential edges of described dust-break umbrella.
Described air flow outlet is provided with blast pipe, and this blast pipe is positioned at the downstream of described dust-break umbrella, and it is indoor that an end of described blast pipe stretches to described cyclonic separation, and the inside of described blast pipe forms the exhaust passage.
Described Whirlwind barrel is the truncated cones shape.
The outward flange of described dust-break umbrella has a upstream face, this upstream face be on the dust-break umbrella at first with the contacted surface of air-flow, the rotation centerline shape of described upstream face and described Whirlwind barrel is a in an angle, and this angle a spends smaller or equal to 70 more than or equal to 35 degree.
Described dust-break umbrella faces described air stream outlet.
Because the present invention has adopted above technical scheme, its advantage is: when ascending air runs into the dust-break umbrella, clean air-flow can continue along rising on the umbrella limit up to discharging from air stream outlet, and fine dust is because inertia can be separated to the inwall of Whirlwind barrel once more, mix with outer gas flow, rotation separates, and improves separative efficiency; On the whole, the ascending air that increase dust-break umbrella can make wraparound carry fine dust secretly can carry out secondary separation, improves the separative efficiency of cyclone separator.

The specific embodiment
A kind of cyclone system for vacuum cleaner to use as shown in Figure 1, comprise Whirlwind barrel 1, usually Whirlwind barrel 1 is the truncated cones shape, this Whirlwind barrel 1 is provided with air flow inlet 11 and air stream outlet 12, the inner chamber of Whirlwind barrel 1 forms cyclone separating chamber 3, be provided with dust-break umbrella 5 in the cyclone separating chamber 3, dust-break umbrella 5 is positioned at the upstream of described air stream outlet 12 and faces toward air stream outlet 12.This dust-break umbrella 5 preferably faces described air stream outlet 12.
The diameter of the outer circumferential edges of dust-break umbrella 5 is being positioned at the cylinder internal diameter that is in same plane with described dust-break umbrella 5 greater than the bore of air stream outlet 12 less than Whirlwind barrel 1.Be arranged so that like this ascending air of carrying fine dust secretly at first collides with dust-break umbrella 5, thereby carry out secondary separation.
The diameter of the outer circumferential edges of dust-break umbrella 5 is preferably Whirlwind barrel 1 and is being positioned at 0.6～0.85 times of cylinder internal diameter that is in same plane with dust-break umbrella 5.
The outward flange of dust-break umbrella 5 has a upstream face 51, this upstream face 51 be on the dust-break umbrella 5 at first with the contacted surface of air-flow, rotation centerline 8 shapes of upstream face 51 and Whirlwind barrel 1 are a in an angle, and this angle a spends smaller or equal to 70 more than or equal to 35 degree.Make that like this can carry out the secondary rotation along this upstream face 51 with the air-flow of carrying fine dust secretly of dust-break umbrella 5 collisions separates.
Among this embodiment shown in the drawings, cyclone separator is vertically placed, and blast pipe 6 is vertically placed so as shown in the figure, dust-break umbrella 5 be positioned at blast pipe 6 under, the lower port of blast pipe 6 faces the upper surface of dust-break umbrella 5, and the above-mentioned upstream face of mentioning 51 is the lower surface of dust-break umbrella 5.
