Wherein, the power of pulsed is more powerful but need use petrol as power, and the former only needs to be electronic, and is more convenient environmental protection during the use.

Most of the existing air-assisted mist sprayers throttle and atomize into liquid drops at the front end of a nozzle, then further break and atomize the liquid drops through high-speed airflow in an air duct, and finally spray the liquid drops under the action of the high-speed airflow. However, this method has a small flow rate, low atomization strength, insufficient atomization, and when the spray size changes, part of the liquid often flows out without being atomized, which causes waste, and the residual liquid medicine corrodes the equipment for a long time.

Detailed Description

The present invention will be further explained with reference to the drawings and the embodiments.

Examples

The multi-pipe type air-assisted atomizing system shown in fig. 1 comprises a fan 1, wherein the fan 1 is communicated with an air guide pipe 2 and an outer bobbin 7; the outer end of the air guide pipe 2 is blocked, and a plurality of first throttling nozzles 3 are formed on the side wall; a plurality of annular liquid guide pipes 4 are axially arranged outside the air guide pipe 2, and a plurality of second throttling nozzles 5 are formed on the inner side walls of the annular liquid guide pipes 4; the annular liquid guide pipes 4 are communicated with the water pump pipe 6; the outer tube 7 is covered outside the annular liquid guide tube 4.

The fan 1 is communicated with the air guide pipe 2 through a throttle pipe 8.

The first throttling nozzle 3 and the second throttling nozzle 5 are oppositely arranged. The annular liquid guide pipes 4 are communicated with each other through a plurality of straight pipes 9; the straight pipes 9 are uniformly arranged along the circumferential direction of the annular liquid guide pipe 4. Preferably, four straight tubes 9 are provided. The air guide pipe 2 and the annular liquid guide pipe 4 are coaxially arranged; the first throttling nozzle 3 and the second throttling nozzle 5 are arranged along the radial direction of the air guide pipe 2.

As shown in fig. 1, the device mainly comprises an outer cylinder tube, an annular liquid guide tube and an air guide tube, wherein the liquid guide tube is fixed on the inner side of the cylinder wall, and the air guide tube is fixed on the inner side of the outer cylinder tube or the liquid guide tube through brackets at the front end and the rear end. Compared with the common air-assisted mist spraying system, the utility model is additionally provided with a plurality of rows of liquid guide pipes and air guide pipes.

Specifically, the utility model discloses improve on the basis of current air-assisted mist system, improve the catheter and be multirow catheter. Meanwhile, the air guide pipe is added. The tail end of the air guide pipe is connected with a water pump pipe to provide liquid medicine for the atomizing system. The rear side is provided with a powerful fan which provides high-speed airflow for mist and spray.

The inner side of the annular liquid guide pipe is provided with a common second throttling nozzle, when liquid in the pipe is sprayed out by the pressure of the pump, the liquid is sprayed out in a high-speed atomized liquid drop mode due to the throttling effect and is released in the whole air pipe; after the high-speed airflow given by the fan is converged and throttled by the throttle pipe, a part of the high-speed airflow enters an annular space between the cylinder wall and the air guide pipe, and a part of the high-speed airflow enters the air guide pipe. Due to the throttling effect the wind speed will increase. The air guide pipe is a single-side opening to form a first throttling nozzle, after air flow enters from one side of the opening, the air flow in the pipe can be sprayed out along the first throttling nozzle (air hole) under the action of air pressure, and the air speed can be increased due to throttling of the air hole.

The powerful fan can provide wind power for the air pipe, so that the atomized liquid drops sprayed from the throttling nozzle are broken and atomized into smaller liquid drops, and the liquid drops move forwards along the annular space between the cylinder wall and the air guide pipe. The common air-assisted mist sprayer only has one annular liquid guide pipe at the front end and does not have a wind guide pipe. The air guide pipe is designed and added, and radial wind is utilized. The airflow in the air guide pipe is ejected out along the radial air holes on the pipe under the action of air pressure, radial impact is generated on atomized liquid drops of the throttling nozzle, atomization of the liquid drops is promoted, the insufficiently atomized liquid drops sprayed from the throttling nozzle are further smashed, and meanwhile, the radial air effectively avoids flow loss caused by the fact that the atomized liquid drops are attached to the outer wall of the air guide pipe in the conveying process. Thus, a part of the atomization work of the liquid drops is dispersed to the radial wind, and the axial wind is more utilized to push the water mist.
