Liquid funnel capable of automatically stopping filling after full filling of container

Abstract

The invention discloses a liquid funnel capable of automatically stopping filling after full filling of a container, and relates to a liquid funnel. The middle of the lower portion face of a funnel body is connected with the upper end of an inserting pipe (8). A necking hole (7) is formed in the upper portion of the inner face of the inserting pipe (8). A long-strip hole (11) is vertically formedin the middle wall of the inserting pipe (8). One or more protruding strips (10) are arranged at the outer edge of the upper portion face of the inserting pipe (8). The middle of a floating rod (14) is arranged in the necking hole (7). A push-pull ring (1) is arranged at the upper end of the floating rod (14). A conical rubber sleeve (16) and a floating ball (17) are arranged at the lower end of the floating rod (14). A lower cover (20) is connected to a pipe body lower portion (12) of the inserting pipe (8). A hole (21) is formed in the middle of the lower cover (20). According to the liquidfunnel, after the container is filled fully, the floating ball in the pipe body lower portion rises and forces the conical rubber sleeve to plug a conical opening, and thus overflow after the container is fully filled with liquid is effectively prevented.

Description

【Technical field】 [0001] The invention relates to a liquid funnel, in particular to a liquid funnel which automatically stops filling when the container is full. 【Background technique】 [0002] It is known that when filling liquids from other containers into bottles, oil pots and other containers, it is necessary to use a leaker as an auxiliary tool in order to prevent the flow caused by the small opening of the container; the current structure of the leaker is a ring plate on the upper part, and the lower part of the ring plate is in the shape of an inverted trumpet Conical plate, set an intubation tube at the lower part of the central part of the conical plate, and set a hook on one side of the ring plate as needed; this structure is very practical in transparent bottles with no limit on loading, but for non-transparent bottles It is difficult to know when to fill up the tank, and it is mostly known when it is filled and overflowed. This not only wastes part of the overflo...

[0002] It is known that when filling liquids from other containers into bottles, oil pots and other containers, it is necessary to use a leaker as an auxiliary tool in order to prevent the flow caused by the small opening of the container; the current structure of the leaker is a ring plate on the upper part, and the lower part of the ring plate is in the shape of an inverted trumpet Conical plate, set an intubation tube at the lower part of the central part of the conical plate, and set a hook on one side of the ring plate as needed; this structure is very practical in transparent bottles with no limit on loading, but for non-transparent bottles It is difficult to know when to fill it up, and it is mostly known only when it is filled and overflowed, which not only wastes part of the overflow solution, but also is very prone to accidents of burns to operators for chemical products that are easy to corrode
