Abstract: A dental irrigator with stepless speed regulation includes a dental irrigator body; a nozzle; a stepless speed regulation component; the dental irrigator body includes a water storage chamber and a movement component embedded in the side of the water storage chamber; the movement component is used to extract water from the water storage chamber; the nozzle is arranged on the top of the movement component, and the nozzle has a water outlet pipe communicated with the movement component for teeth cleaning; the stepless speed regulation component includes an adjustment member rotatably connected to the top of the movement component, an adjustment control panel that controls the working state of the nozzle, and a transmission mechanism installed between the adjustment member and the adjustment control panel; the adjustment member drives the transmission mechanism to control the adjustment control panel to adjust the water outlet rate in the nozzle.

Abstract: Disclosed are a water pump and an oral irrigator. The water pump includes: a water pump assembly, a transmission assembly and a driving member connected in sequence. The water pump assembly includes a water pump housing, a piston is embedded in the water pump housing, and a connecting rod is provided at the piston. The transmission assembly includes a first transmission seat, a first rotating wheel is provided in the first transmission seat, and the first transmission seat is sleeved with a second transmission frame. The second transmission frame drives the connecting rod to perform linear motion, and a driven member is provided between the first rotating wheel and the second transmission frame. The driving member provides rotational power to the first rotating wheel and make the driven member drive the second transmission frame to perform linear motion to make the water pump pump water or deliver water.

Abstract: A portable oral irrigator includes an oral irrigator body, a pump assembly and a nozzle. An oral irrigator water tank is slidably clamped in the oral irrigator body, the pump assembly is installed in the oral irrigator body, an oral irrigator inner cover is installed in the oral irrigator body, an end of the oral irrigator body is provided with an oral irrigator upper cover detachably connected to the oral irrigator body, a first magnet is installed in the oral irrigator upper cover, the oral irrigator upper cover is provided with a first opening for inserting the nozzle, an end of the nozzle is sleeved with a second magnet adsorbing and matching with the first magnet, and the pump assembly pumps water from the oral irrigator water tank and spray water out from the nozzle.

Abstract: Disclosed is an oral irrigator easily disassembled and assembled, and the oral irrigator includes: an oral irrigator nozzle, an oral irrigator upper cover, an oral irrigator inner shell, an oral irrigator main shell and an oral irrigator bottom cover. One end of the oral irrigator main shell is provided with the oral irrigator inner shell and the oral irrigator upper cover in sequence, and the other end of the oral irrigator main shell is detachably connected to the oral irrigator bottom cover. The oral irrigator main shell is provided with a first accommodating cavity and a second accommodating cavity in sequence, and the first accommodating cavity and the second accommodating cavity are separated by a charging base; a water pump mechanism is provided in the first accommodating cavity, and the second accommodating cavity is configured to store water. The oral irrigator inner shell is provided with a locking assembly.

Abstract: Disclosed are a nozzle structure and an oral irrigator thereof. The nozzle structure includes a base and a nozzle connected to the base. The base is provided with a receiving groove, and a whitening agent is provided inside the receiving groove. The base is provided with a water inlet channel communicated with the receiving groove. The nozzle is provided with a water outlet channel configured to facilitate outflow of whitening liquid, and a filter screen for filtering the whitening liquid is installed at one side of the water outlet channel.
