Therefore, in a place where water supply can be connected, such as a toilet or bathroom, the water supply connector 111 can be connected to the water supply line (L1) to use the water supply as washing water. In the case of using a washing device, the water stored in the water tank 20 may be used as washing water by connecting the water supply connector 111 to the stored water supply line L2.

In addition, the microcontroller 170 measures the flow rate of the supplied washing water using the detection signal of the flow sensor 130, determines whether the washing water is constant or stored water based on the size of the measured flow rate, and When the pressure pump 140 is stopped, the instantaneous heating unit 120 and the pulsation pump 150 operate, and when the stored water flows in, the instantaneous heating unit 120, the pressure pump 140 and the pulsation pump 150 By controlling the drive to operate together, the user does not need to operate separately to select an object to be used as washing water, and when the pressure setting value of the pressure pump 140 is set relatively lower than the inlet pressure of the supplied constant, the inflow of constant It is possible to prevent the pressure pump 140 from being damaged or malfunctioning due to pressure.

Here, since the constant supplied from the water supply supply line (L1) connected to the water supply source (10), such as a water tap, is basically introduced at a water pressure of 2.1 to 6.0 kgf/cm2, it is relatively higher than the inflow pressure of the stored water stored in the water tank (20). , and due to the pressure difference flowing into the washing water supply line (L3), the flow sensor 130 detects the water flow due to the water pressure of the constant and the water flow due to the water pressure of the stored water. Difference occurs will do

Therefore, in the microcontroller 170, based on the magnitude of the water flow detection signal input from the flow sensor 130, the decision criterion data for determining whether the incoming washing water is constant or stored water is stored and input in real time based on this It is possible to determine the type of washing water introduced by the detection signal of the flow sensor 130.

On the other hand, the multi-person oral washing device according to a preferred embodiment of the present invention cleans the oral cavity of a pet by connecting the pet handpiece 180 instead of the personal handpiece 160 connected to the water outlet connector 112. It can be used as an oral rinsing device for

To this end, as shown in FIG. 3, the pet handpiece 180 is provided with a plug 181b that is detachably fastened while being inserted into the coupling 195 of the washing water injection line L4 at the lower end, Instead of the personal handpiece 160, the washing water connected to the water outlet connector 112 and supplied to the inner conduit 181 is discharged to the outside through the pet nozzle 182, and the inner conduit 181 is selectively opened and closed. An opening/closing switch 181a for doing so is provided.

In addition, a brush 183 for removing foreign substances by rubbing the inside of the pet's oral cavity is mounted at the front end of the pet nozzle 182, and a discharge for discharging the supplied washing water to the outside is mounted at the center of the brush 183. A ball 187 is provided. Therefore, it is possible to wash the oral cavity of the pet by simply replacing the handpiece connected to the water outlet connector 112, greatly increasing the usability of the device, and the washing water is injected into the oral cavity, so the pet is unconsciously injected. Since the washed water is inhaled, the amount of water intake required for pets with low water intake can be increased.

On the other hand, as shown in FIGS. 4 and 5, the pet nozzle 182 has a nozzle pipe 185 communicating with the inner conduit 181 formed therein so that the washing water is supplied to the nozzle body 184 ), one side is rotatably mounted on the front end side of the nozzle body 184, a brush 183 is provided on the other side, and a discharge hole 187 communicating with the nozzle pipe 185 is formed in the center and supplied It may include a rotating plate 186 for discharging washing water to the outside, and an impeller 188 which is formed in a spiral shape protruding from the inner surface of the discharge hole 187 and rotates the rotary plate 186 while being pressed by the washing water discharged. there is.

Therefore, foreign substances that cannot be removed only with washing water can be removed with the brush 183, and the rotating plate 186 on which the brush 183 is mounted can be rotated to further increase the cleaning effect, and the rotating plate 186 can be operated without a separate power supply. It can be rotated by the discharge pressure of washing water, so maintenance cost can be reduced.

In other words, when the brush 183 directs the discharge hole 187 of the nozzle 162 toward the inside of the oral cavity in a state where the brush 183 is not in contact with the pet's teeth or gums, the teeth or gums are pulsated at high pressure and discharged by the washing water. In this process, the impeller 188 is pressed by the discharge pressure of the washing water, and the rotating plate 186 rotates, and the brush 183 provided on the other side of the rotating plate 186 When they rotate together, the rotating brush 183 can be brought into contact with teeth or gums to effectively remove foreign substances in the oral cavity that cannot be removed only with washing water.

In addition, in the case of the rotating plate 186, since the impeller 188 is spirally formed in only one direction, it rotates in only one direction, and foreign substances may accumulate on protruding parts of teeth or gums in the direction of rotation.

Accordingly, the pet handpiece 180 according to a preferred embodiment of the present invention can provide a washing function that rotates in both directions. To this end, as shown in FIGS. 6 and 7, the pet nozzle 182 has a nozzle pipe 185 communicating with the inner pipe 181 formed therein so that washing water is supplied to the nozzle pipe 185. ) is a nozzle body 184 whose front end side branches into the first branch pipe 185a and the second branch pipe 185b, one side of which is rotatably mounted on one side of the front end of the nozzle body 184, and a brush on the other side. 183a is provided, and a first discharge hole 187a communicating with the first branch pipe 185a is formed at the center to discharge the supplied washing water to the outside; and the nozzle body 184 ), one side is rotatably mounted on the other side of the front end, a brush 183b is provided on the other side, and a discharge hole 187b communicating with the second branch pipe 185b is formed in the center to discharge the supplied washing water to the outside.

A second impeller (188b) rotating in the opposite direction and disposed between the nozzle pipe 185 and each branch pipe (185a, 185b) rotates according to the user's manipulation, and the nozzle pipe of the two branch pipe (185a, 185b) It may include a pipe selection valve 189 for selecting a branch pipe to which the washing water supplied from 185 is supplied.

Therefore, when the pipe selection valve 189 is operated to open the first branch pipe 185a and close the second branch pipe 185b, the washing water supplied to the nozzle pipe 185 flows through the first branch pipe 185a. Only the first rotating plate 186a is rotated by the first impeller 188a, and the washing water is discharged only through the discharge hole 187a of the first rotating plate 186a, and the brush 183a of the first rotating plate 186a In this process, when the pipe selection valve 189 opens the second branch pipe 185b and closes the first branch pipe 185a, the second branch pipe ( Washing water is supplied only to 185b), and the first rotating plate 186a stops and only the second rotating plate 186b rotates, so that the brush 183b of the second rotating plate 186b can rub and wash the teeth or gums. At this time, since the second impeller 188b provided on the second rotating plate 186b is formed in a spiral in the opposite direction to the first impeller 188a provided on the first rotating plate 186a, it is different from the first impeller 188a. will rotate in the opposite direction.

Therefore, compared to the case where the brush is rotated in only one direction, even if there is a protruding portion of a tooth or gum, since the brush is rotated in both directions, it is possible to prevent accumulation of foreign substances on the protruding portion.

On the other hand, in the case of the rotation method of the rotating plates 186, 186a, 186b by the above-described impellers 188, 188a, 188b, the rotation can be easily stopped when the brushes 183, 183a, 183b come into contact with teeth or gums with a certain pressure or more. there is. Accordingly, in the handpiece 180 for pets according to a preferred embodiment of the present invention, the brush 183 may be provided so that the rotating plate 186 rotates by using the force of pressing the teeth or gums.

It may include a compression spring 186d disposed on the rotation plate 186 to elastically pressurize the washing water supply direction.

Therefore, when the tooth or gum is pressed with the brush 183 while the washing water is discharged through the discharge hole 187, the guide block 186c of the rotating plate 186 moves toward the nozzle body 184 along the guide groove 184a. It rotates while moving backward, so that the brush 183 rotates together. In addition, when the pressing force is released, the guide block 186c of the rotating plate 186 rotates while moving forward to the original position along the guide groove 184a by the elastic restoring force of the compression spring 186d, so that the brush 183 rotates in the opposite direction. will rotate

As such, when the brush 183 presses the inside of the oral cavity, the rotating plate 186 rotates by the pressing force and the brush 183 in contact with the inside of the oral cavity can be rotated together, and when the pressing force is released, the compression spring 186d The brush 183 can be further rotated while the rotating plate 186 rotates in the opposite direction by the elastic restoring force of the brush 183, thereby increasing the cleaning effect of the brush 183.

In addition, as shown in the drawing, a flexible pipe 185c is disposed between the rotation plate 186 reciprocating back and forth within the nozzle body 184 and the nozzle tube 185 of the nozzle body 184, so that the front and rear of the rotation plate 186 It is possible to prevent leakage of washing water while supporting the movement, and a bellows pipe 186e is disposed around the outer circumference of the compression spring 186d on the rotation plate 186, and the compression spring 186 is compressed and expanded according to the forward and backward movement of the rotation plate 186. (186d) can be protected from the outside.

On the other hand, as shown in FIG. 9, the multi-person oral washing device according to a preferred embodiment of the present invention is provided with a plug 194 that is detachably fastened while being inserted into the coupling 195 at the lower end, so that the personal hand An opening/closing switch connected to the water outlet connector 112 instead of the piece 160 and discharged to the outside through the nozzles 197 and 198 and selectively opening and closing the inner conduit 191 by washing water supplied to the inner conduit 191 A combined handpiece 190 equipped with 193 may be further included.

In addition, the nozzles 197 and 198 include a personal nozzle 197 having a washing water discharge hole at the end and a pet nozzle 198 equipped with a brush 183 for removing foreign substances by rubbing the inside of the pet's oral cavity at the end. Including, any one of the personal nozzle 197 or pet nozzle 198 may be selectively mounted on the combined handpiece 190. Therefore, compared to the method of replacing the handpiece to change the target of use (for example, individual → pet), it is easy to use and can significantly reduce product purchase costs.
