Fig. 2 is the structural exploded view of the utility model wind blowing gun embodiment.
Fig. 3 is the cross-sectional view of the utility model wind blowing gun embodiment.
Fig. 4 is the partial enlarged view in Fig. 3 at A.
The following is a further explanation of the present invention with reference to the accompanying drawings and embodiments.
Specific embodiment
Referring to Fig. 1 and Fig. 2, the wind blowing gun of the present embodiment includes air intake casing 2, outlet shell 1, handle 3 and for controlling
The micro ball valve 4 of air inflow processed.Air intake casing 2 is fixed on the inlet end of outlet shell 1, and air intake casing 2 has air intake passage 21,
Air intake casing 2 has the outlet passageway 11 being connected with air intake passage 21, and outlet passageway 11 and the air intake passage 21 are same
Axis setting.Air intake passage 21 is in gathering shape, i.e., from the inlet end of air intake casing 2 to the outlet side of air intake casing 2, air intake passage 21
Radius be gradually reduced.The air draught area of 21 air inlet of air intake passage can be increased in the air intake passage 21 for collapsing shape, accelerate air
Flowing velocity, to improve air amplification effect.
Referring to Fig. 3 and Fig. 4, it is formed with annular chamber 12 between air intake casing 2 and outlet shell 1, is offered on outlet shell 1
The air inlet 13 being connected to annular chamber 12 is formed with and annular between the inlet end of outlet shell 1 and the outlet side of air intake casing 2
The gap 14 that chamber 12 is connected to, outlet passageway 11 are connected to gap 14.
The inlet end of outlet shell 1 has cricoid fixed part 15 and cricoid boss 16, and boss 16 is located at fixed part 15
Inside, and there is groove between fixed part 15 and boss 16, the internal perisporium of fixed part 15 is equipped with internal screw thread.Air intake casing 2
Outlet side there is the axial direction columnar part 24, fixed part 25 and the ontology 26 that are sequentially arranged along the air intake casing 2, fixed part
25 outer diameter is greater than the outer diameter of columnar part 24 and is less than the outer diameter of ontology 26.The periphery wall of fixed part 25 is equipped with and fixed part 15
The external screw thread that is cooperatively connected of internal perisporium, external screw thread and screw-internal thread fit are interference fitted outlet shell 1 and air intake casing 2.
And sealing ring 6 is equipped between fixed part 15 and fixed part 25.
Boss 16 is disposed adjacent with columnar part 24 and gap 14 is located between the end of boss 16 and the end of columnar part.Gu
Determine portion 15, boss 16, columnar part 24 and fixed part 25 and surrounds annular chamber 12 jointly.
Annular groove 22 is offered on the internal perisporium at 2 middle part of air intake casing, strainer 23 is installed in annular groove 22.Strainer 23 is used
It is filtered in the air sucked from air intake passage 21, prevents the air for being mixed with the sundries such as dust from blowing out from outlet passageway 11
The surface of spray piece is fallen into afterwards.
The bottom of outlet shell 1 is arranged in handle 3, and the air inlet pipe being threadedly coupled with air inlet 13 is equipped with inside handle 3
31, air inlet pipe 31 has the inlet channel 32 being connected to air inlet 13.The fixed connection place of air inlet pipe 31 and outlet shell 1 is arranged
There is sealing ring 5.
The top of air inlet pipe 31 is threadedly coupled with air inlet 13, the bottom end of air inlet pipe 31 be pierced by from the bottom end of handle 3 and with
Micro ball valve 4 is fixedly connected, and micro ball valve 4 is connected to air inlet pipe 31, and compressed air enters in air inlet 13 from air inlet pipe 31.
Therefore according to venturi principle, after compressed air enters air inlet from air inlet pipe, annular chamber is flowed through and from seam
Clearance flow flows after going out along the direction of air inlet to the gas outlet of outlet passageway of air intake passage, due to the very fast stream of compressed air
It is dynamic, to form negative pressuren zone in the inside of outlet shell, so that large quantity of air is inhaled into air intake passage, not only increase charge air flow
Speed, also increase air mass flow.Wind blowing gun it is compact-sized, small in size, light-weight easy to carry, using the wind blowing gun pair
Single small-sized spray piece, which air-dry, can substantially reduce production cost.In addition, strainer is built in air intake casing, strainer can be prevented
It falls off from air intake casing.
