Speed change gear of automatic skin cleaning bath instrument

Abstract

The invention discloses a speed change gear of an automatic skin cleaning bath instrument, and relates to a bath head. The speed change gear comprises a first same-speed ring, a second same-speed ring and a third same-speed ring; the first same-speed ring includes an outer tooth A, an inner tooth, three small gears, a ring gear A, pin shafts and two glands C; the outer tooth A is arranged on the outer side of the gear ring A; the inner tooth is arranged on the inner side of the gear ring A, and is engaged with the small gears; the pin shafts are respectively arranged in the center positions of the three small gears; the two glands C are respectively positioned on the upper and lower two surfaces of the gear ring A; the second same-speed ring includes a gear ring B, an outer tooth B, an inner tooth, three small gears, pin shafts and two glands B; the outer tooth B is arranged on the outer side of the gear ring B; the inner tooth is arranged on the inner side of the gear ring B; as the outer tooth A, the outer tooth B and an outer tooth C rotate with the same speed, an inner ring, a middle ring and an outer ring of the bath head also rotate with the same speed; and when the three rings of the bath head rotate with the same speed, the bath effect is greatly improved, and more convenience is brought to users.

Description

Technical field: [0001] The invention relates to a scrubbing device, in particular to a speed change gear of an automatic skin cleansing scrubbing device. Background technique: [0002] The application date is September 30, 2015, and the application number is CN201510634325.X, which discloses an automatic skin cleansing scrubbing device, the main content of which includes "the outer teeth A3 mesh with the inner teeth A9, the outer teeth B4 and the inner teeth B10 Mesh and internal tooth B10 is located below internal tooth A9, external tooth C5 meshes with internal tooth C11 and internal tooth C11 is located below internal tooth B10, the bottom of internal tooth C11 is connected to the top of transmission shaft 7, and the bottom of transmission shaft 7 is connected to the motor The transmission gear driven by the "8-connection" motor is three solid gears with different diameters. In the transmission of the gears, it is difficult to achieve the same speed of the inner ring, mi...

[0002] The application date is September 30, 2015, and the application number is CN201510634325.X, which discloses an automatic skin cleansing scrubbing device, the main content of which includes "the outer teeth A3 mesh with the inner teeth A9, the outer teeth B4 and the inner teeth B10 Mesh and internal tooth B10 is located below internal tooth A9, external tooth C5 meshes with internal tooth C11 and internal tooth C11 is located below internal tooth B10, the bottom of internal tooth C11 is connected to the top of transmission shaft 7, and the bottom of transmission shaft 7 is connected to the motor The transmission gear driven by the "8-connection" motor is three solid gears with different diameters. In the transmission of the gears, it is difficult to achieve the same speed of the inner ring, middle ring and outer ring, while the inner ring, middle ring and outer ring rotate at different speeds. It will greatly reduce the skin cleaning effect and bring great inconvenience to users
