Connecting joint for spray connecting pipe of electric sprayer

Abstract

The invention discloses a connecting joint for spraying connecting pipe of an electric sprayer, which discloses a connecting joint for clamping and connecting the connecting pipe of the sprayer by controlling the expansion of the inner air bag and the outer air bag by pressing, and at the same time generating negative pressure for adsorption and fixing, which is characterized in that The shell is a rectangular shell structure, and two pairs of push rods are respectively placed on the upper and lower sides of the shell, one end of the push rod is placed outside the shell, and the other end of the push rod is placed inside the shell through the shell. There is a sealing sleeve for the connection between the push rod and the shell, the sealing sleeve is a rubber sleeve, and the two push buttons are respectively fixed on one end of the two pairs of push rods. A sealing piston is placed in the casing, and is fixedly connected with the other ends of the two pairs of push rods respectively, a sealing ring is sleeved on the sealing piston, an air bag sealing cavity is formed between the sealing piston and the inner wall of the casing, and the spring sleeve is placed on the pushrod between the sealing piston and the inside of the housing.

[0002] At present, in the field of agricultural planting, electric sprayers are generally used to spray pesticides on crops. It saves time and effort, and at the same time eliminates the disadvantages of pesticides being filtered out and harming operators, and has a large spraying distance and range. In the actual use process The spray connecting pipe of the electric sprayer is easy to loosen and fall off at the connection with the sprayer connector, causing great inconvenience to the user, and falling off will also cause pesticides to be sprinkled on the human body, causing harm to the human body. The announcement number CN207188093U discloses a A connection structure for a connecting pipe of an electric sprayer that is convenient to be disassembled, comprising a sprayer body, a hose connected to one side of the sprayer body, and a water inlet pipe connected to the end of the hose away from the sprayer body, and a water inlet pipe connected to the end of the hose away from the hose There is a connecting pipe, and the connection between the connecting pipe and the water inlet pipe is fixedly connected with a fixed box. The top of the fixed box is penetrated by a connecting pipe, and the bottom of the fixed box is penetrated by a water inlet pipe. Both sides of the bottom of the inner wall of the fixed box are There is a spring in the fixed connection. When the splint is used to clamp the connecting pipe, the clamping force of the splint is exerted from both sides, and the connecting pipe is deformed by the inward extrusion force, resulting in the connection between the connecting pipe and the water inlet pipe. There is a gap due to looseness, and the connection is poor in sealing, which is prone to dripping
