Description

Ventilation funnel

Technical Field

The utility model relates to a funnel field, concretely relates to ventilation funnel.

Background

The funnel is a cylindrical object used as a container for injecting liquid and fine powder into the inlet. Because the filler is circular structure usually, when using ordinary funnel to annotate, the outer wall of funnel usually can closely laminate with the filler, when pouring into liquid in the bottle, because the air in the bottle can't be discharged smoothly, leads to injecting into liquid and flows slowly easily, especially when filling oil or more viscous liquid, liquid flow gets more slowly, the unable condition of leaking down of liquid can appear even.

CN2799516Y discloses a double-layer funnel, which belongs to an article for daily use. A small funnel is additionally arranged in the existing funnel, and a certain gap is reserved between two layers of funnels. The funnel solves the problem that when the existing funnel is used, liquid and the funnel are ejected together due to the fact that gas in a bottle cannot be discharged. Although the double-layer funnel can make liquid easily fill into the bottle when in use, the use is very convenient and the structure is simple. However, the gap is easy to enter dust to block, or when some viscous liquid is filled, the liquid is easy to stick above or below the gap to block the gap, and the filling speed is influenced.
