the lower end of the air sealing valve 83 can seal the nozzle of the liquid suction pipe 6 after moving downwards, and the sealing effect can prevent outside air from entering the liquid container in the resetting process after use.
In the present embodiment, the hydraulic chamber 22 is first used to refer to a space formed by the inner chamber a, the interior of the flexible vertical tube 81 and the transition chamber 23; the elastic base can be made of high elastic rubber and other materials with good elastic performance; the elastic ball body A and the elastic ball body B can be made of high-elastic rubber and other materials with good elastic performance and forming performance; the elastic spheres a and B are connected by a relatively short rigid cylindrical body, which may be made of a moisture-resistant, corrosion-resistant rigid plastic.
A spray gun of the construction shown in figures 1 to 5 which, in use: the trigger 3 is pressed down by hand, the return spring 42 is squeezed and compressed by the trigger 3, and the trigger 3 pushes the sliding piston 41 to compress towards the direction of the inner cavity a of the piston cylinder 4 through the mutual matching of the trigger connector 44 and the piston connector 43, so that the pressure of the inner cavity a is increased, and the air sealing valve 83 is pushed to move downwards. When the air-sealing valve 83 moves downwards, the upper end of the air-sealing valve is clamped with the clamping ring 82 and drives the clamping ring 82 to press downwards, so that a part of the elastic vertical pipe 81 above the clamping ring 82 is folded inwards, after the part of the elastic vertical pipe 81 is folded inwards, the sealing effect between the outer side wall of the elastic vertical pipe 81 and the inner side wall of the cylinder through pipe 45 is lost, and at the moment, liquid can enter the liquid outlet channel 21 from the hydraulic cavity 22 and is sprayed out from the spray channel 51 to form water mist;
after the trigger 3 is released, the trigger 3 does not extrude the return spring 42 any more, and the return spring 42 rebounds and drives each structure to reset;
in the resetting process, the matching effect formed by the piston connector 43 and the trigger connector 44 is better than that of a common piston rod, and the effect of driving the sliding piston 41 to reset is better, because the piston rod is usually directly connected to the bottom of the sliding piston 41 and has a larger length, while part of the rigid piston rod has the problems and defects that the piston rod is easy to age and break in the long-term use process and the rigid piston rod is subjected to bending force in the turning process of the trigger 3, and the other part of the elastic piston rod has the problems of poor orientation, easy inclination, poor motion performance of driving the sliding piston 41 by compression and the like. When the piston connector 43 and the trigger connector 44 are matched with each other, firstly, the shorter rigid cylindrical body is not easy to age and break and has good orientation, the elastic ball body A and the elastic ball body B are respectively connected with two ends of the rigid cylindrical body and are respectively positioned at relatively fixed positions with the sliding piston 41 and the trigger 3, but the rotation capacity of the elastic ball body is kept, the bending force applied to the rigid cylindrical body is converted through rotation, so that the elastic ball body per se is stressed and deformed, but the elastic ball body per se has good elasticity and toughness, is small in stress influence, cannot damage the ball body per se, and can still keep good shape characteristics and mechanical properties after long-term use. Therefore, the transmission assembly consisting of the elastic ball A, the elastic ball B and the rigid columnar body overcomes the defects of the existing rigid piston cylinder 4 and the existing elastic piston rod, has the advantages of both, and has good orientation and long service life;
in the spraying process, if the inside and outside of the liquid container can not be timely separated, the trigger 3 is pressed to the bottom and is reset after being released, because the separation structure is not completely reset, a small amount of air can enter the liquid container through the liquid outlet channel 21, so that a small amount of liquid in the liquid outlet channel 21 flows out, at the moment, because the pressure is not strong, the flowing-out liquid is usually in a dripping shape, which is obviously unwilling to see, and in the embodiment, after the single spraying process is finished, the elastic vertical tube 81 has good elasticity in the resetting process of the trigger 3, so that the quick resetting and separation are easily realized, and the generation of the problems is avoided;
in the long-term use process, the elastic vertical tube 81 is always required to be bent when being used every time, the bent part is the part where the upper end of the clamping ring 82 is connected with the elastic vertical tube 81, and the elastic vertical tube 81 is in a high-humidity environment for a long time, the part is easy to age to cause the bent part to lose elasticity, particularly after being frequently used, the problem that the sealing effect of the elastic vertical tube 81 and the cylinder through tube 45 is reduced is easily caused, which is obviously not wanted by people.
