Fig. 2 is the side-looking structural representation of low pressure venturi vacuum spray gun shown in Figure 1.
Fig. 3 is the plan structure schematic diagram of low pressure venturi vacuum spray gun shown in Figure 1.
Fig. 4 is the cutaway view along the A-A line of low pressure venturi vacuum spray gun shown in Figure 3.
The specific embodiment
With reference now to accompanying drawing, describe embodiments of the invention, the similar elements label is represented similar elements in the accompanying drawing.As mentioned above, the present invention is in order to overcome the defective of above-mentioned compressed air vacuum spray gun, provide a kind of improved utilize common in the air blast of drum pressure blower fan replace compressed-air actuated low pressure venturi vacuum spray gun.
Shown in Fig. 1～4, be a kind of low pressure venturi vacuum spray gun of the present invention.This low pressure venturi vacuum spray gun comprise Venturi tube 10 and in be placed in inner sleeve 20 in the described Venturi tube 10, described Venturi tube 10 comprise cavity 11, with the blast pipe 12 of described cavity 11 vertical connections and with the discharge pipe 13 of described cavity 11 horizontal conductings, one end, 111 sealings of described cavity 11,112 transition are communicated with described discharge pipe 13 other end through the conical surface, and the diameter of described discharge pipe 13 is less than the diameter of described cavity 11; Described inner sleeve 20 both ends opens, an and end 21 passes the blind end of described cavity, forms charging aperture 210, the other end 22 place in the described discharge pipe 13 and near the air outlet 130 of described discharge pipes 13, form discharging opening 220; Gap 300 between the inwall of the outer wall of described inner sleeve 20 and described discharge pipe 13 constitutes gas channel, and the described inner sleeve 20 inner parital vacuums that form.
