Description

 Portable bathing machine

Technical field

 The invention relates to a bathing appliance, in particular to a portable bathing machine.

Background technique

 When people are bathing, the scrubbing of the back is not convenient. It is often necessary to ask someone to help with the bathing. Because of this, various bathing facilities that help to scrub the back are born.

 Existing bathing machines include both wall-mounted and hand-held portable. The fixed structure of the wall is relatively complicated and highly automated, but the reliability and safety are lacking, and all the requirements of the installation site are not easy to popularize. However, due to the weight limitation, the existing portable bathing machine often directly drives the back of the head through a single motor, which has low power, low efficiency, unsatisfactory bathing effect, and practicality.

.

 The Chinese utility model patent with the publication number CN201822768U discloses a soft shaft drive bathing device which is connected to the gearbox at one end of the flexible shaft, and the other end is connected to the bathing body, and under the transmission of the flexible shaft, the bathing body The inner bath roller rotates continuously, so that the bath towel provided on the bath roller contacts the human skin. When the bather is in use, the bath towel is in line contact with the human body, but the human body portion which is tangent to the drum is rubbed, the bathing efficiency is poor and the skin is easily damaged, and the sponge body is set in the bath towel to avoid injury. In addition, the bath head is connected to the gearbox through a long flexible shaft, which consumes a large amount of power and is inefficient. When the bather takes a bath, it is greatly affected by the soft shaft, which is not convenient; and the overall structure is too large to be realized. Portable.

The Chinese utility model patent with the publication number CN101278813 discloses a hand-held electric massage bath machine consisting of a telescopic handle, a rack and a massage (bathroom) tray, a rack, an internally mounted reverse switch and an adjustable resistor, an electric motor and The reducer is equipped with a bevel gear shaft at the front end and a massage (bathing) plate on the bevel gear shaft. The back of the bathing machine of the bathing machine is vertically connected with a rotating shaft for driving the rotation thereof, and the front end surface of the bathing tray When the bath is in contact with the human body, the rotational angular velocity of each part of the bathing plate is the same. The surrounding area of the bathing plate is fast due to the large radius of rotation, and the central area of the bathing plate is small due to the small radius of rotation and the center point is small. The line speed is zero, so the front end of the bathing plate has a line speed inconsistency. When the bather takes a bath, the line around the bathing plate is fast, the bathing is very strong, but it is easy to hurt the skin while taking a bath. The line speed in the center of the disc is still small, and the bathing effect is not achieved. In addition, when the artificial bath is taken, the palm sleeve is usually moved along the surface of the human body in the bathing towel, and the bathing method in which the bathing tray rotates on the surface of the human body may cause discomfort.

Summary of the invention
