Embodiment Construction

[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] Please also refer to Figure 1 to Figure 3 , the liquid vertical spray suction device provided by the present invention is now described. The liquid vertical spray back-suction device includes a spray pipe 1 and an inflatable pipe 2. The inside of the spray pipe 1 is provided with a first sealing piston 11. The first sealing piston 11 can move along the axial direction of the spray pipe 1. The first sealing piston 11 will Spray tube 1 is divided into two regions, the bottom of the first sealing piston 11 is liquid cavity 12, the top of the first sealing pis...

Abstract

The invention provides a liquid vertical spray suck-back device and belongs to the technical field of liquid atomizing spraying. The liquid vertical spray suck-back device comprises a spraying tube, an inflating pipe, a pressure relief valve and a controller. A first seal piston is movably arranged in the spraying tube; a nozzle is arranged on the bottom wall of the spraying tube; the top walls ofa first sealing piston and the spraying tube and the side wall of the spraying tube encircle an air cavity; an air pressure detection device is arranged in the air cavity; a push rod is movably arranged in the inflating pipe; a second seal piston is arranged at one end of the push rod while a driving mechanism is arranged at the other end of the push rod; the inflating pipe communicates to the air cavity; the pressure relief valve communicates in the inflating pipe; and the controller is electrically connected to the driving mechanism, the pressure relief mechanism and the air pressure detection device, separately. According to the liquid vertical spray suck-back device, after liquid vertical spray is paused or stopped, a liquid at the nozzle is sucked back to a liquid cavity by reducingthe pressure in the liquid cavity, so that a dripping phenomenon is eliminated. The invention also provides a liquid vertical spray suck-back control method.

Description

technical field [0001] The invention belongs to the technical field of liquid atomization and spraying, and more specifically relates to a liquid vertical spray back-suction device and a liquid vertical spray back-suction control method. Background technique [0002] The liquid atomization spraying process is to put the spraying liquid into a closed container with a nozzle, pressurize the spraying liquid, and after the liquid is pressurized, it is sprayed from the nozzle and atomized. During the atomization spraying process, there is often a phenomenon of liquid leakage after the spray is suspended or stopped, resulting in uneven spraying and wasting spraying liquid. Contents of the invention [0003] The object of the present invention is to provide a liquid vertical spray back-suction device and a liquid vertical spray back-suction control method, aiming to solve the technical problem of dripping during the liquid vertical spray process. [0004] In order to achieve the...
