Experiment, it is determined that the interior diameter for pipe of feeling elated and exultant is preferred in 1.0-3.0CM.
Length of the pipe in cover body of feeling elated and exultant be 4-8CM, oral area can Zi Ran Di Han live to feel elated and exultant and manage.
In order to further prevent dust from entering oral cavity by pipe of feeling elated and exultant, filter screen is installed telling tracheal strips, filter screen can be
Individual layer sand cloth.
The utility model haze effect is good, and smooth breathing is damp proof, anti-exhaust residual, and generation can be avoided to breathe out
Make white on glasses.
