Embodiment 1

[0043] This embodiment provides a liquid drainage structure, such as Figure 1-4 As shown, it includes a liquid outlet 1, which is arranged on the airtight container 2, and is used to connect the inner cavity 20 of the airtight container 2 with the external space, and has a certain axial length; the partition plate 3 is fixedly arranged on the airtight container 2. The inside of the liquid outlet 1 is used to divide the liquid outlet 1 into an air intake channel 11 and a liquid discharge channel 12 arranged up and down; and a baffle plate 4 is fixedly installed on the The part of the partition plate 3 located inside the inner chamber 20, together with the partition plate 3 and part of the inner wall of the airtight container 2, forms a gas flow channel 10 communicating with the inlet passage 11, and the inlet The projection of the air passage 11 on the baffle 4 completely falls into the inside of the baffle 4; the longest distance between the baffle 4 and the liquid outlet 1 i...

Embodiment 2

[0055] This embodiment provides an airtight container on which the liquid drainage structure as described in Embodiment 1 is arranged.

[0056] In this embodiment, the capacity of the airtight container is 1.8 L, the diameter of the liquid outlet is 38 mm, and the cross-sectional area of ​​the air inlet channel is 1 / 4 of the diameter of the liquid outlet.

Abstract

The invention provides a liquid discharging structure and a closed container with the same. The liquid discharging structure comprises a liquid outlet arranged on the closed container, and a partition board arranged inside the liquid outlet to divide the liquid outlet into an air inlet channel and a liquid discharging channel; the part, located inside an inner cavity of the closed cavity, of the partition board is fixedly provided with a baffle used for preventing liquid from directly impacting on the air inlet channel. During using, when the closed container with the liquid discharging structure pours liquid outwards, liquid flows outwards from the liquid discharging channel, external airflow stably and continuously flows into the closed container from the air inlet channel and a gas runner to balance the inner and outer pressure difference, so that the flowing interface of liquid flowing beams is stabilized conveniently, fluctuation and splashing of the liquid flowing beams are reduced, and the pouring speed is increased.

Description

technical field [0001] The invention relates to the technical field of a liquid discharge structure for a closed container, in particular to a liquid discharge structure and a closed container with the liquid discharge structure. Background technique [0002] When the closed container pours liquid outward through the liquid outlet, as the pouring proceeds, the air pressure in the space above the liquid level inside the container will decrease, thereby forming a negative pressure relative to the external environment. [0003] If the caliber of the liquid outlet is small, as the above-mentioned negative pressure continues to increase, the flow rate of the liquid stream discharged from the liquid outlet will decrease, and even eventually stop flowing. This phenomenon is due to the significant effect of the internal surface tension of the liquid outlet, so that the outflow liquid surface remains a smooth overall liquid film, which can form a stable blockage for the liquid outflo...
