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.

Claims (13)

1. A dental irrigator with stepless speed regulation, comprising:

a dental irrigator body; a nozzle; a stepless speed regulation component;

wherein the dental irrigator body comprises 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 connected with the movement component for teeth cleaning;

the stepless speed regulation component is installed above the water outlet pipe; the stepless speed regulation component comprises 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;

the movement component comprises a casing, a fixing frame and a top cover; the casing is clamped to the side of the water storage chamber; the fixing frame is provided on the top of the casing to carry the adjustment member and the transmission mechanism; the top cover penetrates the fixing frame and is fixedly inserted into the top of the casing;

the movement component also comprises a main control panel, and the adjustment control panel is signally connected to the main control panel;

the adjustment member comprises a main gear ring, the main gear ring is rotatably sleeved on the top of the fixing frame, and part of the main gear ring is arranged outside the casing;
