Some facial cleansing brushes use magnetic levitation vibration to drive the metal piece in front of the magnet to resonate. Some of the main structures of facial cleansing brushes are motors, circuit boards and rechargeable batteries. Either way, it is cleaned by vibration, however,The facial cleansing brush whose structure is a motor and a gearbox from ZHAOWEI has its own characteristics.
The main function of the electric facial cleansing brushes is to fully combine and emulsify the cleansing products with the dirt on the skin through vibration. For the facial cleansing device, if the structure is small, the torque may not be enough to cause the washing power to be insufficiently cleaned; if the structure is too complicated, the volume may be too large, which is not portable for vocation, or the cleaning force is too large, and the surface skin is easily damaged. It can be seen that a good facial cleansing device is mainly used to remove makeup and clean the skin, and it is gentle and dose not hurt the skin.so how to make a good facial cleansing device?
Some facial cleansing brushes use magnetic levitation vibration to drive the metal piece in front of the magnet to resonate. Some of the main structures of facial cleansing brushes are motors, circuit boards and rechargeable batteries. They all have their advantages,but their common feature is to clean by vibration. The next i will introduce a facial cleansing brush whose important structure is a micro motor and a micro gearbox.The working principle is the gearbox driven by a motor,after reducing speed and increasing torque,then driving the brush to swing for cleaning.
Realizing multi-stages transmission needs
In order to solve multi-stages transmission needs of facial cleansing brush,ZHAOWEI adopts to the 16mm planetary gearbox to achieve positive and negative adjustment of facial cleansing brush,meanwhile,the product has two-stage, three-stage, four-stage transmission changes,and its reduction ratio,input speed and torque can be adjusted according to the requirements of facial cleansing brush.
In addition to the stability of washing force,the “buzzing” noise of the face washer is more annoying in the operation.In order to solve this problem, the gears in the planetary gear box of the facial cleansing brush are made of noise-reducing materials, and the material has self-lubricating property to reduce product noise.
If the transmission system of the facial cleansing brush don’t have long life,It’s still not competitive.In order to improve the service life and quality of the products, Zhaowei uses kinematics simulation to verify the smoothness and local interference of the gear pair movement in the gear and gearbox design stage. At the same time, the finite element analysis technology is used to analyze and check the tooth surface strength of the spiral teeth and bevel gears. The cavity pressure technology is used to detect changes in cavity pressure during injection molding and to monitor product quality.
