Detailed description of the invention:
Embodiment: following describing in detail is done to the present invention below in conjunction with accompanying drawing.For sake of convenience, following " on ", D score, "left", "right" be consistent with the direction, upper and lower, left and right of accompanying drawing itself.
As shown in Fig. 1 ~ 2, a kind of spray equipment, comprises spray gun 20 and coating case 10; Coating case 10 is fixed on the front end of spray gun 20; Screen pack 11 is fixed with in the middle part of coating case 10; Screen pack 11 is divided into upper tank 101 and lower tank 102 coating case 10; Nozzle 103 is formed bottom coating case 10; The 4th pipeline 104 is formed in sidewall bottom coating case 10; 4th pipeline 104 one end outlet is arranged on bottom coating case 10 right side wall, other end outlet nozzle 103 is connected; 4th pipeline 104 is fixed with the 4th check valve 105; Spray gun 20 inside is fixed with cylinder 22; Cylinder 22 piston rod passes the right side wall of coating case 10 and is connected with a pushing block 221; Cylinder 22 right side wall is connected with the first pipeline 205 and the second pipeline 204; First pipeline 205 is fixed with the first check valve 206; Second pipeline 204 is fixed with the second check valve 209; First pipeline 205 other end is connected with coating case 10 upper tank 101; Cylinder 22 left side wall is connected with the 3rd pipeline 202; 3rd pipeline 202 is fixed with the 3rd check valve 203; The other end of the second pipeline 204 and the 3rd pipeline 202 is connected on distributor 21; Distributor 21 is T-shaped in what lie on one's side; Distributor 21 is plugged in spray gun 20; Distributor 21 bottom is plugged on the guide groove 208 in spray gun 20 right-hand member lower wall; Distributor 21 inside forms L-type passage; Gas tube 201 is inserted with on the right side of L-type passage; Holding rod 232 is fixed with on the right side of spray gun 20; Distributor 21 bottom-hinged has a trigger 23; Be hinged in the middle part of trigger on holding rod 232.
Stage clip 231 is connected with between the bottom of trigger 23 and the bottom of holding rod 232.
Distributor 21 bottom-hinged has between a trigger 23 and is hinged with a connecting rod.
Size and the lower tank 102 of pushing block 221 are measure-alike.
Spray gun 20 inside bottom end face is fixed with limited block 207.
During real work, pulling trigger 23 makes distributor 21 forward, due to the existence of limited block 207, second pipeline 204 is connected with gas tube 201 by distributor 21, gas opens the second check valve 209, gas enters the right cavity of cylinder 22, gas push piston rod also drives pushing block 221 and opens the upper tank 101 that the first check valve 206 enters coating case 10 along the first pipeline 205 and extrude coating, such coating can enter lower tank 102 by screen pack 11, and simultaneously pushing block 221 fails to agree in moving handle coating and squeezed out injection in nozzle 103.
Trigger 23 is under the effect of stage clip 231, trigger 23 travels forward and impels distributor 22 rearward, 3rd pipeline 202 is connected with gas tube 201 by distributor 21, gas opens the 3rd check valve 203 enters cylinder 22 left cavity along the 3rd pipeline 202, gas push piston rod also drives pushing block 221 to left movement, the upper tank 101 that the gas in the right cavity of cylinder 22 will be impelled like this to enter coating case 10 along the first pipeline 205 continues extruding coating, simultaneously due to can coating be there is in lower tank 221 rightward space, along with pushing block 221 is to left movement, coating can enter the 4th pipeline 104 and open the 4th check valve 105 and squeeze out injection from nozzle 103.
So no matter distributor 21 left or move right, coating can carry out filtering and spouting from nozzle always, can improve filter efficiency like this.
