Funnel device

Abstract

This invention relates to a funnel device, comprising: a funnel body, a cover, and an adapter. The funnel body includes a receiving portion and a discharging portion that are connected and internally communicate with each other. The receiving portion has a receiving interface on a side away from the discharging portion, and the discharging portion has a flow outlet. The cover includes a base and a positioning unit. The base covers the receiving portion to cover the receiving interface, and the positioning unit is located on the base. The adapter can be selectively connected to either the positioning unit or the discharging portion. The adapter forms a conduit that communicates with the flow outlet, and the adapter includes a connection portion for connecting with a substance to be injected.
