2. The self-cleaning dental irrigator of claim 1, wherein: the water pump also comprises an elastic piece, the valve body is provided with a through hole which penetrates through the valve body and is communicated with the water pump core, the valve core is movably accommodated in the through hole, and the nozzle piece and the water pipe are respectively communicated with the through hole; the regulating unit is an electromagnetic coil arranged on the tooth flusher main body or the valve body, and the valve core is made of a magnetic conductive material; the electrified regulating unit generates magnetism and attracts the valve core, so that the valve core blocks the communication between the nozzle piece and the through hole and opens the communication between the water passing pipe and the through hole; the regulation and control unit loses magnetism and does not attract the valve core after power loss, and the elastic piece drives the valve core to reset under the action of elastic restoring force so that the valve core blocks the communication between the water passing pipe and the through hole and opens the communication between the nozzle piece and the through hole.

3. The self-cleaning dental irrigator of claim 2, wherein: the tooth-washing device also comprises a spacer block which is arranged on the tooth-washing device main body and is matched with the nozzle piece, the spacer block is provided with a base part and a blocking head part arranged on the base part, the outer diameter of the base part is larger than that of the blocking head part, and the valve core is provided with a through hole which penetrates through the valve core and is used for communicating the water pumping machine core with the nozzle piece; the base part is provided with a yielding hole for communicating the nozzle piece with the through hole, and the plug part is used for blocking the through hole.

4. The self-cleaning dental irrigator of claim 3, wherein: the valve body is provided with a first annular groove, and the regulating and controlling unit is sleeved on the outer side of the valve body and is accommodated in the first annular groove; the elastic piece is a spring, one side of the elastic piece is abutted against one end of the base part close to the plug part and is arranged around the plug part, and the other end of the elastic piece is abutted against the valve core.

5. The self-cleaning dental irrigator of claim 3, wherein: the first sealing ring is sleeved on the outer side of the plug part, the plug part is provided with a second ring groove for accommodating the first sealing ring, and the first sealing ring is accommodated in the second ring groove and protrudes out of the outer surface of the plug part; the valve core is provided with a taper hole communicated with the through hole, and the first sealing ring is used for abutting against the side face of the inner hole of the taper hole to separate the communication between the abdicating hole and the through hole.

6. The self-cleaning dental irrigator of claim 2, wherein: the valve core is provided with a third annular groove used for accommodating the second sealing ring, and the second sealing ring abuts against the side surface of the inner hole of the through hole to seal a gap between the valve core and the valve body; the valve body is provided with a backflow hole which is communicated with the water passing pipe and the through hole, the control unit after being electrified generates magnetism and attracts the valve core, so that the valve core blocks the communication between the nozzle piece and the through hole, and the second sealing ring is positioned between the backflow hole and the nozzle piece; the regulation and control unit after losing the electricity loses magnetism and does not attract the case, and the elastic component drives the case under the effect of elastic restoring force and resets so that the case blocks up the intercommunication of water pipe and through-hole, and the backward flow hole is located between two second sealing rings.

7. The self-cleaning dental irrigator of claim 1, wherein: the sprinkler bead is the cone globoid, and the external diameter that the sprinkler bead is close to water pipe one end is less than the external diameter that the sprinkler bead kept away from water pipe one end, and the sprinkler bead is equipped with a plurality of apopores with the water pipe intercommunication, and a plurality of apopores set up around the central axis of sprinkler bead.

8. The self-cleaning dental irrigator of claim 7, wherein: the sprinkler bead is equipped with the cavity inner chamber with the water pipe intercommunication, apopore and cavity inner chamber intercommunication, and the apopore sets up on the lateral wall of sprinkler bead, and a plurality of apopores are arranged from the one end that the sprinkler bead is close to the water pipe to the one end that the sprinkler bead kept away from the water pipe.

9. The self-cleaning dental irrigator of claim 1, wherein: the liquid storage tank is provided with a liquid storage cavity for containing cleaning liquid, and the tooth flusher main body is slidingly contained in the liquid storage cavity; the outer side of the lower end of the tooth flusher main body is sleeved with a third sealing ring, the tooth flusher main body is provided with a fourth ring groove used for accommodating the third sealing ring, and the third sealing ring is used for sealing a gap between the tooth flusher main body and the liquid storage tank; the upper end and the lower end of the outer side of the tooth flushing device main body are provided with protruding parts, the upper end of the liquid storage box is provided with a stopping part positioned in the liquid storage box, the stopping part is positioned between the protruding parts at the upper end and the lower end of the tooth flushing device main body, and the stopping part is used for abutting against the protruding parts.
