Abstract: Embodiments of the present disclosure provide a method for measuring a movement of the cervical vertebra, a device thereof and a wearable apparatus. The method for measuring a movement of the cervical vertebra comprises: obtaining a movement angle of the cervical vertebra with a sensor; and calculating a movement amount of the cervical vertebra based on the movement angle of the cervical vertebra. Therefore, according to embodiments of the present disclosure, exact data values of the movement angles of the cervical vertebra can be acquired with the sensor, and the movement amount of the cervical vertebra can be calculated on the basis of this, thereby a quantitative value of the movement of the cervical vertebra can be acquired exactly in form of a numerical value, which is convenient for future processings.

Abstract: The embodiments of the present invention relate to a spray head and a body cleaning device, the spray head comprising: a spray head body comprising a panel provided with spray holes, the panel being provided with a plurality of brush rods, each of which forming a spheroid at an end portion thereof that faces away from the spray head body. The spheroid is made of an elastic material. The spray head, during its use, can penetrate through hair to thoroughly clean the scalp and the bottom portion of the hair near the scalp.
