Pawing device for head-washing machine

Abstract

The invention provides a pawing device for a head-washing machine and relates to the head-washing machine. The pawing device has a simple structure and can precisely control running positions and the massaging force degree of paws. The pawing device is provided with a guide rail bracket, a guide rail, a guide rail motor, a guide rail driving mechanism, at least one pawing mechanisms and a controlcircuit, wherein the guide rail and the guide rail bracket are rotatably connected; a driving gear of the guide rail driving mechanism is connected with an output shaft of the guide rail motor; a driven gear of the guide rail driving mechanism is in linkage connection with the guide rail; a pawing seat motor, a pawing seat driving mechanism, a pawing arm and a pawing arm steering engine of the pawing mechanism are arranged on a pawing seat; a pressure sensor is arranged at the front end of the pawing arm; the pawing seat driving mechanism is a paired roller component; the paired roller component is provided with a driving guide wheel and a driven guide wheel; the driving guide wheel and the driven guide wheel clamp the guide rail and are matched with the guide rail in a rolling way; the pawing arm is rotatably connected with the pawing arm seat through a rotation shaft; and the output shaft of the pawing arm steering engine is connected with the rotation shaft of the pawing arm.

Description

technical field [0001] The invention relates to a hair washing machine, in particular to a claw device for the hair washing machine. Background technique [0002] When the claw (mechanical arm) of the existing hair washing machine presses the head, although it can realize three-dimensional movement, it has obvious disadvantages: 1. The claw is not flexible enough to reach various parts of the head accurately and flexibly ; 2. The strength control of the claws is relatively poor, and the requirement of equal pressing pressure at each point cannot be realized; 3. The structure is more complicated and the cost is high, so it is difficult to popularize. [0003] The utility model patent with the notification number CN201282814 provides an automatic hair washing machine, which includes a helmet-shaped housing, a water-inlet shower head is arranged on the upper part of the helmet-shaped housing, and an air-pressure waterproof shower head is provided in the helmet-shaped housing. ...
