At this time, the slide groove of the salad body is formed to be combined with a metal material such as aluminum, stainless steel to increase the wear resistance to prevent wear.

At this time, the check ball 281 is sprayed on the top of the through-hole 273 of the cylinder body 270 has a reciprocating or pulsating cycle of the two kinds of water and sterilization liquid, and sprayed to the water jet nipple 274 The cylinder valve 280 which has is formed.

At this time, the liquid mixing tank 290 is coupled to the upper side of the cylinder valve 280, the liquid mixing tank is formed with a coupling pipe 291 to be coupled to the open communication hole 282 of the cylinder valve.

At this time, one side and the other side in communication with the joint pipe 291 is formed with a first connecting pipe 292 for the water bottle and the second connecting pipe 293 for the liquid cartridge to collect and mix the water and sterilizing solution.

At this time, while controlling the presence of water to the first connecting pipe (292) for the water tank, while preventing the back flow of water when the piston arm 250 is pressurized, the water in the water tank 150 leaks to the nozzle 340 when the operation stops Separate liquid control valve (294) is provided to block to be made.

At this time, the liquid control valve 294 is preferably further installed on the pipe before the inlet of the second connecting pipe to prevent the back flow of the sterilization liquid of the liquid cartridge is formed to prevent the back flow of the sterilizing liquid of the liquid cartridge.

Thus, the pumping device 200 is formed to control and control the flow rate and flow rate of the mixed solution of water and sterilization liquid mixed in accordance with the rotational speed of the motor 220 as an embodiment, the sterilization liquid of the liquid cartridge 140 Is preferably formed to adjust the flow rate in accordance with the set opening and closing time of the liquid control valve (294).

At this time, the stroke distance induction structure 251 of the piston shaft is formed to be designed in the range of 1: 2 ~ 1: 5 of the elliptical horizontal: vertical diameter ratio is formed to cause the pulsation of ultra-fine period by the stroke distance of the piston. On the inner circumferential surface of the stroke distance inducing structure, wear prevention metal plates 251-1, such as aluminum (Al) and stainless steel (SUS), are preferably combined.

In addition, it is preferable that a metal liner 271 such as aluminum (Al) or stainless steel (SUS) be further coupled to the slide groove 272 of the cylinder body to prevent abrasion of the inner circumferential surface due to linear reciprocation of the piston 260. .

At this time, it is preferable that the packing 263 of the non-metal material is coupled to at least one packing groove 262 at the tip of the outer circumferential surface of the piston 260 to prevent leakage.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
