Technical Field
The invention relates to an automatic quantitative liquid outlet cover and a using method thereof.
Background
The bottle of the liquid storage body is generally provided with a bottle cap, and the bottle cap is generally in threaded connection with the bottle opening of the bottle. To pour the liquid from the bottle, the cap is unscrewed from the bottle mouth and the liquid is poured into the cup. When the liquid is poured, the bottle mouth needs to be inclined downwards or inverted, and the bottle needs to be stably held. However, children often feel unstable when holding the bottle when pouring the liquid, and carelessly pour out excessive liquid, or even pour out the liquid in the bottle at one time. It is therefore desirable to design a bottle cap that is attached to the mouth of a bottle, can pour out the liquid inside the bottle without removing the bottle cap, and can prevent the liquid inside the bottle from being poured out at one time.

Preferably, the liquid pouring pipe and the main cover body are coaxial.
Preferably, the first end of the liquid pouring pipe is positioned inside the main cover body.
The invention also provides a use method of the automatic quantitative liquid outlet cover, which comprises the following steps:
taking a bottle with liquid, and mounting a main cover body on a bottle opening of the bottle (the main cover body is in threaded connection with the bottle opening);
when the liquid in the bottle is not required to be poured out, the bottle is upright, the bottle opening of the bottle is upward, and the liquid outlet of the liquid pouring pipe is upward; the piston, the connecting rod, the support frame and the end plug move downwards under the action of gravity until the support frame is erected on the annular convex edge; at the moment, the end plug moves downwards to the position below the liquid pouring pipe, the inner cavity of the bottle is communicated with the inner cavity of the liquid pouring pipe, the piston moves downwards to the position below the liquid outlet of the liquid pouring pipe, and the liquid outlet of the liquid pouring pipe is separated from the inner cavity of the bottle by the piston, so that liquid in the bottle is separated from the environment outside the liquid outlet of the liquid pouring pipe;
when the liquid in the bottle needs to be poured out, the bottle is inverted, the bottle opening of the bottle is inclined downwards, and the liquid outlet of the liquid pouring pipe is downwards; the liquid in the bottle continuously flows into the liquid pouring pipe; the end plug, the connecting rod, the support frame and the piston move downwards under the action of gravity and the pressure of liquid in the bottle; when the piston moves downwards to the liquid outlet of the liquid pouring tube, the liquid in the liquid pouring tube can continuously flow out from the liquid outlet; until the end plug is pressed on the annular convex edge; at the moment, the piston is attached to the inner wall of the second end of the liquid pouring tube, the end plug is tightly pressed on the annular convex edge under the action of gravity and the pressure of liquid in the bottle, the end plug and the annular convex edge form sealing fit, the liquid in the bottle cannot continuously flow into the liquid pouring tube, the liquid in the bottle is prevented from continuously flowing out, and the liquid in the bottle is prevented from being poured out at one time;
because the amount of liquid poured out at one time is limited, if more liquid needs to be poured out, the liquid can be poured out for a plurality of times, and before the liquid is poured out each time, the bottle is erected or nearly erected, the bottle opening of the bottle is upward, so that the end plug is moved downwards to be separated from the annular convex edge, and the inner cavity of the bottle is communicated with the inner cavity of the liquid pouring tube.
The invention has the advantages and beneficial effects that: the automatic quantitative cap for liquid outlet is a bottle cap which is arranged on the bottle mouth of a bottle, so that liquid in the bottle can be poured out without taking the bottle cap off the bottle mouth, the liquid in the bottle can be prevented from being poured out at one time, the amount of the liquid poured out at each time is almost the same, and quantitative liquid outlet can be basically realized.
The built-in weight of piston, when falling liquid (the liquid outlet of liquid pouring tube is down), the weight can make end plug and piston move down more smoothly, reduces the inside liquid buoyancy of bottle and to the influence that the end plug moved down, makes the piston more quick move down to paste and lean on the inner wall at liquid pouring tube second end, and then more smoothly pours liquid.
When the piston moves down fast to abut against the inner wall of the second end of the liquid pouring tube, the end plug is just pressed on the annular convex edge and forms sealing fit with the annular convex edge, so that the liquid in the bottle cannot flow into the liquid pouring tube continuously; therefore, the amount of the poured liquid is almost the same when the liquid is poured every time, and the quantitative liquid discharge can be basically realized.
