Then the novice brush head had better have a soft adhesive to prevent tooth knocking. Although the cost will double, the safety can be improved. After the soft adhesive is degraded by sunlight, it can also encourage users to buy a new brush head ~ ~ (the effect found on Panasonic's brush head ~ ~)

It is best to have a dual-use brush head that can spray water from the top of the brush head to strengthen the cleaning effect on the back side of the molars.

It is actually a rare right-angle nozzle, which helps to clean the back side of the molars, not bad. But the lack of similar Panasonic DJ-10 against the gums when the pressure relief gap ...... It is best to be like Ou Lin W1, into a soft rubber pressure relief gap, not only can relieve pressure but also can prevent collision teeth.

The water spray hole of the best toothbrush is also sprayed from the top.

In addition, it is better to use the elastic film pump similar to the single gas drum diaphragm pump in Inpley to increase the internal water leakage prevention effect (but it is not clear whether the patent authorization is easy to buy?) ...... A little curious about whether the multi-gas drum diaphragm pump can simulate the pulse effect if it is matched with the circuit of intermittent power failure?

Think of a problem, the brush head is active, the plunger pump and the hollow spindle is a dynamic seal structure between the brush head to move 30000 times per minute, this sealing structure can maintain how long?

This is called a sonic toothbrush and a dental irrigator all-in-one machine, and it is also called an electric toothbrush to bury the selling points.

A refreshing feeling
