In general, the dental caries and gum disease has been added to the importance of oral care as a problem of caries and gum disease in recent years is known that prevention of the most important.

Therefore, in order to solve the problem of gum disease caused by tartar and tooth pain caused by dental caries, thorough oral care and dental care should be followed.

In other words, dental care can be destroyed in a moment if you care a little, the best oral care is necessary.

However, brushing is the most important part of the oral care, but it is not easy to remove the foreign substances between the teeth and the cause of tartar between the gums and teeth with only brushing.

Accordingly, various types of oral cleaners have been developed that can clean foreign substances caught between teeth.

Such a conventional mouthwash has the advantage of cleaning the teeth simpler, faster and more effectively than a toothbrush or floss.

Thus, the oral scrubber is a conventional oral scrubber was developed to wash the teeth between the gum and the scrubber to clean the teeth inside the oral cavity by spraying the water forcibly pumped by the pump attached to the scrubber body through the water pressure generated at this time Is done.

On the other side of the piston arm 250, a circular coupling ball 252 is formed to be coupled to the insertion groove 261 of the piston 260; The piston 260 assembled with the coupling ball 252 is a slide groove having a liner 271 therein to be slid into the cylinder body 270 to have a reciprocating or pulsating period during rotation of the motor 220 ( 272 is formed, the slide groove 272 is in communication with the through hole (273) and at the same time the cylinder body (270) is formed so as to communicate with the outer water jetting nipple (274); The cylinder having a check ball 281 to the two kinds of water and sterilization liquid mixed with the reciprocating or pulsating cycle at the upper end of the through-hole 273 of the cylinder body 270, and to be injected into the water jet nipple 274 A valve 280 is formed, and an open communication hole 282 is formed above the cylinder valve 280; A joint pipe 291 is formed to be coupled to the communication hole 282 of the cylinder valve 280, and the first and the second bucket for water so as to recruit and mix water and sterilization liquid on one side and the other side in communication with the joint pipe 291. A connecting pipe 292 and a second connecting pipe 293 for the liquid cartridge are formed, and the first connecting pipe for the bucket 292 side to control the presence or absence of water supply, while the back pressure of the water when the piston arm 250 is pressed For oral irrigator, characterized in that the liquid mixing tank 290 is provided with a separate liquid control valve 294 is installed to prevent and stop the water of the bucket 150 leaks to the nozzle 340 when the operation stops. Reciprocating or pulsating fluid pressurized pumping device. 3. The stroke distance inducing structure 251 of the piston shaft according to claim 2, wherein
The elliptical width: vertical diameter ratio is designed to be designed in the range of 1: 2 to 1: 5, and is formed to cause pulsation of ultra-fine period by the stroke distance of the piston, and aluminum (Al) is formed on the inner circumferential surface of the stroke distance inducing structure. Reciprocating or pulsating fluid pressure pumping device for an oral irrigator, characterized in that the wear-resistant metal plate (251-1), such as stainless (SUS) is coupled. [4] The slide groove 272 of the cylinder body is further coupled with a metal liner 271 such as aluminum (Al) and stainless steel (SUS) to prevent abrasion of the inner circumferential surface due to linear reciprocation of the piston 260. Reciprocating or pulsating fluid pressure pumping device for an oral irrigator characterized in that it is. 5. The reciprocating or pulsating oral cavity for oral irrigator of claim 4, wherein a non-metallic packing 263 is coupled to at least one packing groove 262 at the tip of the outer circumferential surface of the piston 260 to prevent leakage. Hydrostatic pressure pumping device.
