JZ9 Servo Vibration Sweeping Electric Toothbrush Made in Beijing Beijing-This product will be listed in 2024, which should be my first product to follow up the whole process. From the preliminary concept sketch, man-machine deliberation, scheme iteration, CMF process verification, structural model test, to the final mass production.

The core proposition of the project is to transform the underlying technology of servo 60-degree swing sweeping vibration into an electric toothbrush that is easy for ordinary people to use, take good care of and adapt to bathroom scenes, and restore the cleaning logic of pasteurized brushing, which is different from the traditional single sound wave vibration scheme.

In the early sketch stage, the multi-version direction is diverged around the holding of man-machine, the proportion of the whole machine and the interactive form of the panel. Synchronously make a hand-held grass mold to verify the grip and distribution of the center of gravity, so as to solve the problem of top-heavy similar products.
The appearance is determined to be a very simple cylindrical shape, and IML in-mold injection molding integrated panel scheme is selected to reduce gaps, toothpaste stains are not easy to accumulate in humid bathroom environment, and both beauty and durability are taken into account. The final color matching is bright moon white and silk satin silver.

Continue to cooperate with the structure and hardware team, follow up EVT/DVT multi-round mold test, and verify the appearance surface, key feel, assembly clearance and waterproof performance. Synchronously polish the brush head shape and cushioning structure to balance the cleaning force and gum protection experience; Finalize the complete set of functional experiences such as IPX8 waterproof, 120-day long endurance, APP customization and zone change reminder.

I don't know if there are any people who happen to buy and use Puxiang who can share it. I bought seven or eight sets myself and sent them to my family and friends. The feedback is all right.
