Claims

[Scope of utility model registration request]

It has a valve device that opens and closes a fluid passage formed in the head part so as to establish continuity between a nozzle protruding from one end of the head part and an input side passage leading to a fluid supply source opened at the other end of the head part. The valve device has a valve insertion hole that is opened in the head portion and communicates with the fluid flow path, and an axial through hole that is removably tightly fitted into the insertion hole, and this through hole is formed in the middle part. With the tapered hole as a boundary, one end is a piston fitting part, the other end is a ball built-in part, and a communication hole communicating with the nozzle is provided in a part of the piston fitting part near the taper hole part, and the ball is connected to the ball. A valve cylinder whose built-in part communicates with a fluid supply source, and a valve cylinder that is slidably and tightly fitted into the above-mentioned piston fitting part of this cylinder, and whose base end is a protrusion that protrudes outward from the head part and has an operating rod at the tip of the head. The piston rod has a piston rod that is elastically energized to face outward, and a hole that is elastically energized so as to be in pressure contact with the tapered hole portion built in the ball built-in portion of the valve cylinder. By moving the rod forward, the ball is separated from the tapered hole to conduct the fluid flow path, and by moving the piston rod back, the ball is brought into pressure contact with the tapered hole to open the fluid flow path. is made to continue, and furthermore, after this continuous movement, the piston rond is made to move backward, thereby creating a negative pressure in the nozzle side flow path and sucking the fluid remaining in the output side flow path. dental cleaning equipment.
