[0015] Beneficial effects of the utility model:

[0016] The utility model provides an atomizer. When liquid is atomized in an atomizing container shell, a part of the liquid is not atomized, causing waste of resources. In order to solve the above problem, the liquid that is not vaporized flows back to the bottom end of the inner part of the atomizing container shell and accumulates. When the refluxed liquid reaches a certain amount and triggers the upper sensing point and the lower sensing point in the liquid level sensor, the liquid level sensor sends a signal to a PLC controller, that is, it is determined that the accumulated liquid is relatively large. The PLC controller controls the servo motor to stop conveying liquid into the atomizing container shell. At this time, the atomizing nozzle utilizes the gas siphon principle to return the unvaporized liquid accumulated at the bottom end of the inner part of the atomizing container shell to the atomizing nozzle through the oil return conduit for secondary atomization. On the contrary, when the lower sensing point in the liquid level sensor is not triggered, it is not necessary to turn off the servo motor, which effectively prevents waste of resources caused by the liquid that is not atomized.

[0017] In addition, the amount of liquid extruded into the atomizer container shell is accurately controlled by the suction extrusion structure arranged on the top of the oil tank. When the amount of extruded liquid reaches the set value, the suction extrusion structure no longer continues to transport liquid into the atomizer container shell, and the liquid enters the atomizer container shell for atomization. The unatomized liquid is repeatedly atomized again in the atomizer container shell with the cooperation of the oil return mechanism until the liquid in the atomizer container shell is completely atomized, thereby achieving accurate control of the liquid atomization dose and meeting the requirements of mixing ratio coordination.

During operation, when the liquid is atomized in the atomizing container shell 1, a part of the liquid is not atomized, resulting in a waste of resources. In order to solve the above problem, when the liquid and the gas enter the atomizing container shell through the oil inlet conduit 3 and the air inlet conduit 4 respectively, When the liquid is in the body 1, the liquid sprayed by the atomizing nozzle 2 collides and shears strongly with the air flow, and is ejected and hits the metal grid plate 9 to vaporize and form an aerosol. The vaporized aerosol is then discharged through the mist outlet pipe 6, and the unvaporized liquid flows back to the bottom end of the inner part of the atomizing container shell 1 to accumulate. When the refluxed liquid reaches a certain amount and triggers the upper sensing point and the lower sensing point in the liquid level sensor 8, the liquid level sensor 8 sends a signal to the PLC controller 27, that is, it is determined that the accumulated liquid is large. The PLC controller 27 controls the servo motor 12 to stop conveying liquid into the atomizing container shell 1. At this time, the atomizing nozzle 2 uses the gas siphon principle to return the unvaporized liquid accumulated at the bottom end of the inner part of the atomizing container shell 1 through the oil return conduit 5 to the atomizing nozzle 2 for secondary atomization. On the contrary, when the lower sensing point in the liquid level sensor 8 is not triggered, there is no need to turn off the servo motor 12, which effectively prevents the waste of resources caused by the unatomized liquid.

A first one-way valve 22 is fixedly assembled between the oil suction conduit 17 and the oil inlet of the cylinder body 11, and the first one-way valve 22 limits the oil to flow only from the oil tank 10 to the cylinder body 11. A second one-way valve 23 is fixedly assembled between the oil inlet conduit 3 and the oil outlet of the cylinder body 11, and the second one-way valve 23 limits the oil to flow only from the cylinder body 11 to the atomizing container housing 1; including a PLC controller 27, and the PLC controller 27 is electrically connected to the liquid level sensor 8, the servo motor 12, the first limit switch 20, and the second limit switch 21 through wires;

[0029] A limit mechanism is provided on one side of the cylinder body 11, and the limit mechanism includes a movable hole 18 opened on one side of the cylinder body 11, a limit push rod 19 is fixedly provided on one side of the sleeve 15, and a first limit switch 20 and a second limit switch 21 are fixedly installed on one side of the cylinder body 11, respectively. When the first limit switch 20 is triggered by the limit push rod 19, the oil in the cylinder body 11 has been completely pushed out from the oil inlet conduit 3, and when the second limit switch 21 is triggered by the limit push rod 19, the oil in the cylinder body 11 has been fully pumped out from the oil suction conduit 17; when working, the first limit switch 20 is triggered by the limit push rod 19, and the second limit switch 21 is triggered by the limit push rod 19, and the oil in the cylinder body 11 is completely pumped out from the oil suction conduit 17; First, the liquid needs to be filled from the oil tank 10 into the cylinder 11 and then transported to the atomizer container housing 1. The PLC controller 27 starts the servo motor 12, and the servo motor 12 drives the screw 13 to rotate, and at the same time drives the moving block 14 to move, and the moving block 14 drives the sleeve 15 to move, and the sleeve 15 drives the piston 16 to move in the direction of the servo motor 12. The first one-way valve 22 is opened and the liquid enters the cylinder 11 through the oil suction conduit 17. When the liquid is sucked in, the second one-way valve 23 is in a closed state, and the sleeve 15 drives the limit push rod 19 while moving. When the limit push rod 19 triggers the second limit switch 21, the second limit switch 21 sends a signal to the PLC controller 27, and the PLC controller 27 reversely controls the servo motor 12 to stop pumping liquid into the cylinder 11, and pumps the liquid out of the cylinder 11 again, and the screw rod 13 reverses to make the moving block 14, the sleeve 15, and the piston 16 move in the opposite direction, and the piston 16 pushes the liquid out of the cylinder 11. After the liquid enters the oil inlet conduit 3, the second one-way valve 23 is opened, and the liquid enters the mist through the oil inlet conduit 3. Atomization is carried out in the container shell 1. At this time, the first one-way valve 22 is in a closed state. At the same time, the sleeve 15 drives the limit push rod 19 to move toward the first limit switch 20. When the limit push rod 19 triggers the first limit switch 20, the first limit switch 20 sends a signal to the PLC controller 27. The PLC controller 27 again reversely controls the servo motor 12 to continue to pump liquid into the cylinder body 11, and the liquid is transported in a reciprocating cycle. The PLC controller 27 can control the rotation speed of the servo motor 12, thereby controlling the amount of extruded liquid.

[0030] Furthermore, a proportional valve 24 is provided on one side of the atomizing container shell 1, and the outlet position of the proportional valve 24 is connected to the atomizing nozzle 2 through the air inlet duct 4. A solenoid valve 26 is provided on one side of the proportional valve 24, and the outlet of the solenoid valve 26 is connected to the inlet of the proportional valve 24 through a connecting pipe 25. The PLC controller 27 is included, and the proportional valve 24, the solenoid valve 26 and the PLC controller 27 are electrically connected through a wire. When working, the liquid needs to cooperate with the gas to complete the atomization solenoid valve 26 to control the entry of the gas, and the proportional valve 24 limits the proportion of the entering gas. The gas then enters the atomizing nozzle 2 through the air inlet duct 4 to cooperate to complete the atomization.

[0031] Working principle: First, the liquid needs to be filled from the oil tank 10 into the cylinder 11 and then transported to the atomizer container housing 1. The PLC controller 27 starts the servo motor 12. The servo motor 12 drives the screw rod 13 to rotate, and at the same time drives the moving block 14 to move. The moving block 14 drives the sleeve 15 to move, and the sleeve 15 drives the piston 16 to move in the direction of the servo motor 12. The first one-way valve 22 is opened and the liquid enters the cylinder 11 through the oil suction conduit 17. When the liquid is sucked in, the second one-way valve 23 is in a closed state, and the sleeve 15 drives the limit push rod 19 to move toward the second limit switch 21 while moving. When the limit push rod 19 triggers the second limit switch 21, the second limit switch 21 sends a signal to the PLC controller 27. The PLC controller 27 reversely controls the servo motor 12 to stop pumping liquid into the cylinder 11, and pumps the liquid out of the cylinder 11 again. The screw rod 13 reverses to make the moving block 14, the sleeve 15, and the piston 16 When the piston 16 moves in the opposite direction, the piston 16 pushes the liquid in the cylinder 11 out. After the liquid enters the oil inlet conduit 3, the second one-way valve 23 is opened and the liquid enters the atomizing container housing 1 through the oil inlet conduit 3 for atomization. At this time, the first one-way valve 22 is in a closed state, and the sleeve 15 drives the limit push rod 19 to move toward the first limit switch 20. When the limit push rod 19 triggers the first limit switch 20, the first limit switch 20 sends a signal to the PLC controller 27. The PLC controller 27 again reversely controls the servo motor 12 to continue to draw liquid into the cylinder 11, and the liquid is transported in a reciprocating cycle. The PLC controller 27 can control the rotation speed of the servo motor 12, and then control the amount of extruded liquid. The liquid needs to cooperate with the gas to complete the atomization. The solenoid valve 26 controls the entry of the gas, and the proportional valve 24 limits the proportion of the gas entering. The gas then enters the atomizing nozzle 2 through the air inlet conduit 4 to complete the atomization.

[0032] When the liquid is atomized in the atomizing container shell 1, a part of the liquid is not atomized, resulting in a waste of resources. In order to solve the above problem, when the liquid and the gas enter the atomizing container shell 1 through the oil inlet conduit 3 and the air inlet conduit 4 respectively, the liquid sprayed by the atomizing nozzle 2 collides and shears strongly with the air flow, and is ejected and hits the metal grid plate 9 to be vaporized to form an aerosol. The vaporized aerosol is then discharged through the mist outlet pipe 6, and the unvaporized liquid flows back to the bottom end of the atomizing container shell 1 to accumulate. When the refluxed liquid reaches a certain amount, the liquid level sensor 8 is triggered, and the liquid level sensor 8 sends a signal to the PLC controller 27. The PLC controller 27 controls the servo motor 12 to stop conveying liquid into the atomizing container shell 1. At this time, the atomizing nozzle 2 uses the gas siphon principle to return the unvaporized liquid accumulated at the bottom end of the atomizing container shell 1 through the oil return conduit 5 to the atomizing nozzle 2 for secondary atomization, thereby effectively preventing the waste of resources caused by the unatomized liquid.
