High-airtightness anti-liquid sticking nozzle

Abstract

The invention discloses a high-airtightness anti-liquid sticking nozzle comprising a tube wall and a guide port. The guide port is formed in the end part of an opening of the tube wall; a liquid collecting hopper is arranged below the guide port; the liquid collecting hopper is attached to the tube wall; a liquid collecting cavity used for collecting excess liquid flowing out from the guide port is arranged in the liquid collecting hopper; a return through hole is formed in the tube wall; the return through hole enables the inner side of the tube wall to communicate with the liquid collectingcavity; the inner side of the tube wall is also provided with a sealing device used for opening and closing the return through hole; the sealing device comprises a sealing plate; the bottom part of the sealing plate is connected with the inner surface of the tube wall in an overturning manner; the top part of the sealing plate is provided with a floating cavity overturning upwards along with flowing of liquid; the floating cavity is hollow or is provided with a substance less than the liquid in density; and when the liquid flows through the sealing plate, the sealing plate is driven to close the return through hole. A solution dangling from the guide port is collected through the liquid collecting hopper, and returns into a container again through the return through hole; and the sealing device is used for controlling the return through hole to avoid the phenomenon that the solution overflows from the return through hole when poured by a user.

Description

technical field [0001] The invention relates to the mouth of a container, in particular to a high-tightness anti-hanging liquid mouth. Background technique [0002] At present, the container generally has a mouth through which the liquid in the container is poured out, such as oil bottles, laundry detergent bottles, thermos bottles, etc. [0003] In order to avoid the phenomenon of hanging liquid at the mouth of the bottle when pouring liquid, there is a mouth in the prior art, the mouth is provided with a liquid collection bucket on the outer wall, and a channel is provided on the liquid collection bucket to connect back to the mouth of the mouth; and The inner wall of the mouth is provided with a sealing plate that can float on the liquid, and when the liquid is poured, it can be flipped up to close the channel with the change of the height of the liquid. The sealing plate is provided with a film, and the channel is sealed by the deformation of the film. [0004] However,...

Problems solved by technology

[0004] However, under this structure, the connection effect between the film and the sealing plate is poor, so that the film and the sealing plate are prone to detachment, which affects the sealing effect on the channel, so that when the mouth is pouring liquid, the liquid will flow from the channel. Leaking out, affecting the use effect
