[0014] Technical effects and advantages of the utility model:

[0015] The utility model divides the inside of the dispensing bottle into two cavities, a left chamber and a right chamber, which can store two liquids without interfering with each other. At the same time, through the design of the double pump of the nozzle part, the two liquids can be sucked out at the same time when in use, mixed in the piston cylinder, and sprayed out. At the same time, when the liquid is sucked out, there are sealing surfaces on the upper and lower sides of one side of the ball valve, and there is no sealing surface on the upper side of the one-way valve on the other side, so the liquid can be sucked in freely. There are sealing surfaces on the upper and lower sides of the one-way valve. When the liquid is sucked in by jumping, it will be sealed by the sealing inclined surface in the marble limit column when it moves up a certain distance. The liquid can be sucked in quantitatively and can be passed through the slow flow valve The setting of the slow-flow valve plate causes the suction to deform and allow liquid to enter. Due to the existence of the slow-flow valve plate and the limited degree of deformation, the liquid is buffered when it enters, thereby achieving the effect of slowing down the flow rate of the liquid. When there is no suction pressure, the slow-flow valve plate will immediately return to its original position, and the sealing spherical surface on the slow-flow valve plate cooperates with the sealing bottom surface on the slow-flow valve body to form a seal, so that the sucked-up liquid will not flow back, thereby making the ball valve jump rate stable, so that the liquid suction amount can be more accurate and stable, thereby achieving precise quantitative mixing of two liquids for spraying. It is more powerful than traditional sprayers and greatly improves practicality. BRIEF DESCRIPTION OF THE DRAWINGS

Generally, 2-3 sealing ribs 2901 and sealing grooves 3103 are provided.

[0032] Working principle of this utility model:

[0033] When in use, the piston 6 is moved in the gun body 7 by pressing the hand, so that the gas in the gun body 7 flows and the pressure becomes smaller, while the pressure outside the gun body 7 remains unchanged. A pressure difference is generated inside and outside the gun body 7, and two kinds of liquids are sucked out from the left chamber 2201 and the right chamber 2202 respectively. There are sealing surfaces on the upper and lower parts of the ball valve. When the liquid is sucked in by jumping, it will be sealed by the sealing inclined surface in the marble limit column 1103 when it moves up a certain distance, so that the liquid can be sucked in quantitatively, and when the liquid is sucked out upward, it passes through the slow-flow valve, and the slow-flow valve plate 30 is deformed by the suction force to allow the liquid to enter. Due to the existence of the slow-flow valve plate 30 and the limited degree of deformation, the liquid is buffered when it enters, thereby achieving the effect of slowing down the flow rate of the liquid. When there is no suction pressure, the slow-flow valve plate 30 will immediately return to its original position, and the sealing spherical surface 3001 on the slow-flow valve plate 30 cooperates with the sealing bottom surface 3101 on the slow-flow valve body 31 to form a seal, so that the sucked liquid can be When the liquid is sucked in, the small ball valve 14 will be affected by gravity and fall to the lower sealing surface, and the liquid will not flow back. The flap valve 18 will be affected by the suction pressure during suction, and the flap valve 18 will jump. The liquid is sucked in and then affected by the elastic force of the small spring 17, which presses the flap valve 18 on the sealing surface, and the liquid will not flow back. The two one-way valves work to make the amount of the left and right sucked liquids a certain proportion. The sucked liquid enters from 1003 and mixes in the piston cylinder. The pressure difference is formed by extrusion to guide the liquid out of the gun body 7. When the liquid encounters the high-speed airflow, it is instantly atomized. After the liquid in the two bottle cavities is discharged, the pressure is different from that of the outside world, so that 25 and flap valve three 27 are opened to make the pressure the same. When the pressure is the same, under the action of the small spring 26 and the small spring 3 28, the flap valve 25 and the flap valve 3 27 are pressed on the sealing surface again to form a seal.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
