Description

  The present invention relates to a structure of a portable oral irrigator pump, and relates to a pump structure that is used in a portable oral irrigator and controls launch and discharge.

  At present, many portable oral cleaners use a motor to move an pump in conjunction with an eccentric device, pressurize water with the pump, pass through a pipe, and eject it from a jet nozzle of the oral cleaner. Most of the pumps used in the conventional mouth washer are thin film pumps, and push out water by suction force and propulsion force generated when the thin film inside the pump is pushed and pulled. However, since this type of pump sucks in sufficient water by performing high-speed and high-frequency suction and propulsion of the thin film, vibration and noise are generated during use. In addition, the thin film vibration causes water inhalation and extrusion action, and since the thin film is a soft material, water absorption is insufficient, and a strong pressure fountain action cannot be formed. With this, a sufficient oral cleaning effect cannot be exhibited.

  However, the above-described device has drawbacks in use and needs to be improved. The cause is as follows.

  Most of the pumps used in conventional oral cleaners are thin film pumps, and water is pushed out by the suction force and propulsion force generated when the thin film inside the pump is pushed and pulled back and forth. By performing it frequently, it draws in enough water, causing vibration and noise during use. Many of the pumps used in conventional oral cleaners are thin-film pumps, and the thin-film vibration causes water inhalation and extrusion, and the thin film is a soft material, resulting in insufficient water absorption and a strong pressure fountain. It cannot be performed, and a sufficient oral cleaning effect cannot be exhibited.

  The present invention has been made in view of the above-mentioned problems, and its purpose is to produce a stable and sufficient amount of water flow because the pump is more closely attached and does not leak even when high-pressure water flow is used. An object of the present invention is to provide a portable oral irrigator pump structure that can improve the effectiveness of oral cleaning and reduce noise and failure rate.

In the portable mouth washer pump structure according to the present invention, the pump includes a pump body, a water outlet connector, a launch connector, and a reciprocating drive unit.
The pump body includes a water outlet, a launch port, and a piston chamber.
The launch connector and the discharge connector are respectively connected to the launch port and the discharge port of the pump body.
At least one pair of fitting ears is respectively installed on the outer edge of the launch outlet and the outlet of the pump body.
At least one set of fitting connection portions that are fitted and connected to the fitting ears of the pump body launching port and the water discharge port outer edge portion are also installed on the outer edge portion of the fitting connection end of the water discharge connector and the water discharge connector.
Each fitting connection portion is formed with a fitting tank into which the fitting ears of the pump body launching port and the outlet edge of the water outlet are fitted, and the lower edge of the inlet of each fitting tank and under the fitting end of each fitting ear. A corresponding slope is installed on each edge.
And the bottom edge of the fitting end of each fitting ear is slightly lower than the bottom edge of each fitting tank, so that the water outlet connector and the launch connector are fitted and connected to the water outlet and launch outlet of the pump body, respectively. Can be fitted with each washer more smoothly and tightly.
At the same time, a water leakage prevention resin body is separately filled in the gap formed when the water outlet connector and the water launch connector are fitted and connected to the water outlet and the water outlet of the pump body.

  In the present invention, the reciprocating drive unit pushes and reciprocates the piston in the piston chamber of the pump main body due to the above-described components, thereby causing a continuous operation of reciprocating advance. At this time, a high-pressure water flow of water absorption and fountain is continuously generated. However, water leakage does not occur, thereby making the water supply stronger and more stable and enhancing the effect of oral cleaning.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings.

  A structure of a portable mouth washer pump according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 4, in the structure of the portable mouth washer pump, the pump 1 includes a pump body 11, a water discharge connector 12, a launch connector 13, and a reciprocating drive unit 14. The pump body 11 includes a water outlet 112, a water outlet 111, and a piston chamber 113. The launch connector 13 and the discharge connector 12 are connected to the launch port 111 and the discharge port 112 of the pump main body 11, respectively. At least one pair of fitting ears 1112 and 1122 are installed on the outer edge portions of the launch port 111 and the water outlet 112 of the pump body 11, respectively. At least one set of fittings that are fitted and connected to the fitting ears 1112 and 1122 of the outer edge of the pump main body 11 and the outlet 112 also on the outer edge of the fitting connection end of the outlet connector 12 and the launching connector 13. Connection parts 132 and 121 are installed. The fitting connection parts 132 and 121 are formed with fitting tanks 133 and 122 into which the fitting ears 1112 and 1122 at the outer edge portions of the pump body 11 launch port 111 and the water outlet 112 are fitted. In addition, corresponding inclined surfaces 1331, 1221, 1113, and 1123 are respectively installed on the inlet lower edges of the fitting tanks 133 and 122 and the fitting edge lower edges of the fitting ears 1112 and 1122. And the fitting end lower edge surfaces 1114 and 1124 of the fitting ears 1112 and 1122 are slightly lower than the design of the lower edge surfaces 1332 and 1222 of the fitting tanks 133 and 122, respectively. Washers 1121 and 1111 are installed at the water outlet 112 and the launch outlet 111 of the pump body 11, respectively. As a result, when the water outlet connector 12 and the water launch connector 13 are fitted and connected to the water outlet 112 and the water outlet 111 of the pump body 11, respectively, the washers 1121 and 1111 can be more smoothly and tightly fitted. (See FIGS. 5, 6, 7, and 8). At the same time, the water leakage prevention resin body 3 is separately filled in the gaps A and B generated when the outlet connector 12 and the launch connector 13 are connected to the outlet 112 and the launch port 111 of the pump body 11 (see FIG. 9). Thereby, the reciprocating drive unit 14 pushes and reciprocates the piston 1131 in the piston chamber 113 of the pump main body 11 to cause a continuous operation of reciprocating advance. At this time, even if a high-pressure water flow of water absorption and fountain is continuously generated, water leakage does not occur, thereby making the water supply stronger and more stable and enhancing the effect of oral cleaning.

  Ball bodies 134 and 114 that receive the restoring force of springs 135 and 115 are installed in the launch port 111 and the water outlet 112, respectively. The ball body 134 installed in the launch port 111 normally receives the restoring force of the spring 135 and is pushed by the launch hole 131 in the launch connector 13. The ball body 114 installed at the water outlet 112 receives the restoring force of the spring 135 and is pushed by the water outlet hole 116 of the pump body 11. When the piston 1131 is pushed upward and moves, the water in the piston chamber 113 is compressed and pressurized. Thereby, the ball body 134 recovers and seals the position of the launch hole 131 of the launch connector 13, and pushes and opens the ball body 114 installed at the position of the water outlet hole 116 of the pump body 11. Thereby, the water enters the jet nozzle 15 via the water outlet connector 12 and is ejected.

  The reciprocating drive unit 14 includes a motor 141 and an eccentric drive gear 142. The rotation of the eccentric drive gear 142 is driven by the motor 141, the piston 1131 is pushed by the connecting rod 1132, and the reciprocating motion is performed. Thereby, the water absorption pipe 136 absorbs water in the water tank 21 below the case 2 and ejects it from the jet nozzle 15 attached to the top end of the water outlet connector 12. A localization control push button 151 is installed at the apex end of the water outlet connector 12. As a result, it is possible to control the loosening or orientation of the jet nozzle 15. In the case 2, a battery 221 that supplies power to the motor 141 is installed, and a switch 22 that controls turning on or off of the motor 141 is installed.
