The utility model discloses an
oral irrigator with stepless speed change and pressure regulation function, which comprises a main body shell, an
oral irrigator water pump, a main control PCB (
printed circuit board) and a panel component, the panel component comprises a panel, an
encoder, a rotating shaft and a roller, the panel component is fixed on the main body shell, the
oral irrigator water pump is assembled in the main body shell, and the main control PCB is arranged on the main body shell. The
encoder is fixedly installed on the inner side face of the panel, the rotating shaft penetrates through the rolling wheel and is fixedly connected with the rolling wheel, one end of the rotating shaft is connected with the
encoder, the rolling wheel is rotated left and right to drive the interior of the encoder to rotate for control and adjustment, and stepless speed
change control over the
water pressure of a water pump of the die
punching device is achieved. According to the utility model, the panel
assembly is provided with the encoder with a stepless speed change pressure regulating function; the rotating roller in the design is used for regulating the
water pressure by rotating fingers left and right when the oral irrigator is held by a hand; the method is more suitable for ergonomics; in addition, a
consumer can more accurately match the gear force suitable for the
consumer, the tooth washing experience comfort degree is improved, the number of assemblies is small, assembling is easy, the occupied size is small, and the portable tooth washing device is suitable for a small-size portable tooth washing device.
