Abstract
A siphon type air blowing gun set comprises a casing and an annular airflow guide ring, wherein the casing comprises an air inlet passage, an air outlet passage and an air suction passage which are mutually communicated; the air outlet passage and the air suction passage are basically located on the same straight line; and the annular airflow guide ring is clamped between the air outlet passage and the air suction passage. The annular airflow guide ring is arranged between the air outlet passage and the air suction passage of an air blowing gun, a large air outlet volume can be produced by using a small quantity of air sources according to a siphon principle, and the blowing-out air is smooth and uniform.
Description
Technical field
The utility model relates to a kind of blowing rifle group cover, especially a kind of hydrocone type blowing rifle group cover.
Background technology
The blowing rifle has played important effect in industrial production, be applicable to and remove dust, powder, bits end and moisture, is best suited for air and cleans, cools off and drying.The air-out of existing blowing rifle directly drives fan by electro-motor and rotates and blow out from the air-out passage, and single this kind blowing rifle blowing efficient is low, and air output is little, and the air that blows out is also inhomogeneous.
The utility model content
Technical problem to be solved in the utility model provides a kind of hydrocone type blowing rifle, be provided with annular baffle liner between the outlet passageway of this blowing rifle and the air intake passage, use a small amount of source of the gas can produce huge air output according to siphon principle, air-out is mild, even.
In order to solve existing technical problem, the technical solution adopted in the utility model is: a kind of hydrocone type blowing rifle group cover, comprise housing and annular baffle liner, described housing has inlet channel, outlet passageway, the air intake passage that is interconnected, outlet passageway and air intake passage are located along the same line substantially, and described annular baffle liner is fastened between outlet passageway and the air intake passage.
Above-mentioned a kind of blowing rifle group cover, the outer circumference surface of described annular baffle liner is corresponding with the inlet end of inlet channel, and annular baffle liner becomes big from the side near outlet passageway gradually to the diameter near air intake passage one side.
Above-mentioned a kind of blowing rifle group cover, the outer circumference surface of described annular baffle liner is the smooth butt conical surface.
Above-mentioned a kind of blowing rifle group cover, the outer circumference surface of described annular baffle liner is provided with the guiding gutter that a plurality of circular array are evenly arranged.
The beneficial effects of the utility model are: be provided with annular baffle liner between the outlet passageway of this blowing rifle and the air intake passage, use a small amount of source of the gas can produce huge air output according to siphon principle, air-out is mild, even.

The specific embodiment
Further understand and be familiar with for making architectural feature of the present utility model and the effect reached had, cooperate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 1 and Figure 2, a kind of hydrocone type blowing rifle group cover, comprise housing 1 and annular baffle liner 2, housing 1 has inlet channel 11, outlet passageway 12, the air intake passage 13 that is interconnected, outlet passageway 12 and air intake passage 13 are located along the same line substantially, annular baffle liner 2 is fastened between outlet passageway 12 and the air intake passage 13, the outer circumference surface of annular baffle liner 2 is corresponding with the inlet end of inlet channel 11, and annular baffle liner 2 becomes big from the side 21 near outlet passageway gradually to the diameter near air intake passage one side 22.
As improvement of the present utility model, the outer circumference surface of annular baffle liner 2 is the smooth butt conical surface, and the outer circumference surface of annular baffle liner 2 is provided with the guiding gutter 23 that a plurality of circular array are evenly arranged.
When the work of blowing rifle, the air that blasts from inlet channel 11 contacts with the outer circumference surface of annular baffle liner 2, because annular baffle liner 2 is provided with guiding gutter 23, air enters into outlet passageway 12 along guiding gutter 23, because the flow velocity of air is very fast, outlet passageway 12 and air intake passage 13 have formed bigger pressure difference, the blowing rifle is inhaled in the housing 1 near the extraneous gas of air intake passage 13 1 sides, enter into outlet passageway 12 along air intake passage 13, this blowing rifle only need blast a spot of source of the gas, can spray a large amount of air, adopts siphon principle, the air-flow of producing by boasting from the blowing rifle is very stable, and is mild.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and the specification is principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in the claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
