The water source may be provided by the water tank 205 or connected to tap water, preferably, the water source is preferably provided by the water tank 205 in order to improve the convenience of the dental irrigator. The water pump 203 can be controlled to be started or stopped by a switch 206, a mounting hole 207 for mounting the switch 206 is formed in the side face of the shell 200, the switch 206 is mounted on the mounting hole 207 in the outer side face of the shell 200 and protrudes out of the surface of the shell 200, and the switch 206 is electrically connected to the water pump 203 or the power supply 204, so that the tooth flushing device can be operated conveniently.
Further, the cavity of the housing 200 is divided into an upper cavity 208, a middle cavity 209 and a lower cavity 210 by two annular partition plates, the upper cavity 208 is provided with an upper end cover 211, and the upper end cover 211 can be fastened and connected with the upper cavity 208 by screw threads. The lower chamber 210 is provided with a lower end cap 212, and the lower end cap 212 can be mounted by screwing to the lower chamber 210. The nozzle 202 is tightly installed in the upper cavity 208, the water pump 203 and the power supply 204 are tightly installed in the middle cavity 209, and the water tank 205 is tightly installed in the lower cavity 210, so that the whole structure is compact and ordered, and the production and implementation are convenient.
Further, the nozzle 202 is of a hollow cylinder structure with one end being large, a water flow channel is formed in the hollow part of the nozzle 202, and the nozzle 202 can be manufactured and molded by copper or stainless steel, so that the service life of the entire tooth flusher can be prolonged. Two ends of the nozzle 202 are respectively matched with two sealing gaskets 213 to be installed in the upper cavity 208, so that water flow is prevented from leaking and the pressure of the water flow is reduced. Two positioning rings 214 are provided inside the nozzle 202, the positioning rings 214 are provided inside the nozzle 202 at intervals forward and backward in the axial direction of the nozzle 202, and specifically, the positioning rings 214 are connected to the inner wall of the nozzle 202 by uniformly arranged ribs 215; two positioning rings 214 are provided with center rods 216, the front ends of the center rods 216 are formed with shearing parts 217, the rear parts of the center rods 216 are formed with racks 218, and the racks 218 can be matched with gears 219 to drive and control the center rods 216 to reciprocate back and forth along the axial line direction of the nozzle 202. The external diameter size of shearing part 217 is adapted to the size of the water flow channel on the upper end of nozzle 202, and in practical application, the upper end of nozzle 202 is smaller than the lower end, and a sudden change water flow channel connected through the sudden change of the cone is formed inside, so that the water outlet pressure of water flow can be obviously improved, and the cleaning effect of the tooth flushing device is improved.
Further, the gear 219 may be connected by a lever (not shown) extending to the outside of the housing 200 and installed to be engaged with the housing 200, and the lever may be installed by a sealing ring (not shown) when installed at the nozzle 202, so as to prevent the water flow in the nozzle 202 from leaking out and reduce the water flow pressure. Specifically, a first through hole (not shown) is provided on the outer side of the upper chamber 208 for fitting the lever to extend to the outside of the housing 200, and a second through hole 220 is provided on the outer side of the nozzle 202 for fitting the lever through the nozzle 202. Actuation of the lever causes the center rod 216 to adjust the water flow either forward or backward, thereby controlling the water flow pressure to the rinse head 201. When the central rod 216 moves upward, the flow rate at the water outlet of the nozzle 202 decreases, and the water flow pressure increases; as the center rod 216 moves downward, the flow rate at the outlet of the nozzle 202 increases and the pressure of the water stream decreases. The operating rod cooperates with the gear 219 and the rack 218 to operate the center rod 216, so that the operation is convenient and the structure is compact.
