Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
The utility model discloses the technical scheme of specific implementation as follows:
as shown in fig. 1 to 4, the present invention provides a bottle cap capable of controlling liquid discharge, which comprises a main cap body 1 with a downward opening, wherein an inner thread 11 is arranged on the inner peripheral wall of the main cap body 1;
a vertically arranged liquid outlet pipe 2 penetrates through the top wall of the main cover body 1, a liquid outlet 21 is arranged on one side of the top end of the liquid outlet pipe 2, a liquid inlet 22 is arranged at the bottom end of the liquid outlet pipe 2, and an inner convex ring 23 extends from the inner peripheral wall of the liquid inlet 22;
an inner plug 3 which can be in sealing fit with the inner convex ring 23 is also arranged right below the liquid inlet 22, and the inner plug 3 is in a flat disc shape;
a vertically-arranged connecting rod 4 extending into the liquid outlet pipe 2 extends from the center of the top surface of the inner plug 3, and the length of the connecting rod 4 is not more than the distance between the liquid outlet 21 and the liquid inlet 22;
the top end of the connecting rod 4 is provided with a supporting frame 5; the supporting frame 5 is in a cross shape and comprises four supporting arms 51 distributed in a cross shape, the four supporting arms 51 are positioned on the same plane, and the plane is vertical to the connecting rod 4; the four support arms 51 are the same length; the inner ends of the four supporting arms 51 are all connected with the connecting rod 4, and the outer ends of the four supporting arms 51 are respectively in sliding fit with the inner peripheral wall of the liquid outlet pipe 2.
The utility model discloses the application method of bottle lid as follows:
taking a bottle with liquid, and installing a main cover body 1 on a bottle opening of the bottle (the bottle opening is provided with external threads, and the main cover body 1 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, the liquid inlet 22 of the liquid outlet pipe 2 is downward, and the liquid outlet 21 of the liquid outlet pipe 2 is upward; the inner plug 3, the connecting rod 4 and the supporting frame 5 fall under the action of gravity until the supporting frame 5 falls on the inner convex ring 23 of the liquid inlet 22, as shown in fig. 3; at the moment, the four supporting arms 51 of the supporting frame 5 are erected on the inner convex ring 23 of the liquid inlet 22, the supporting frame 5 pulls the inner plug 3 through the connecting rod 4, the inner plug 3 falls below the liquid inlet 22, and the inner cavity of the bottle is communicated with the inner cavity of the liquid outlet pipe 2;
when liquid in the bottle needs to be poured out, the bottle is obliquely poured, the bottle opening of the bottle faces downwards, the liquid inlet 22 of the liquid outlet pipe 2 faces upwards, and the liquid outlet 21 faces downwards; the liquid in the bottle flows out through the liquid outlet pipe 2 and the liquid outlet 21 thereof; in the process of liquid flowing out, the inner plug 3, the connecting rod 4 and the supporting frame 5 fall under the action of gravity and the pressure of the liquid in the bottle until the inner plug 3 falls on the inner annular ring 23 of the liquid inlet 22, as shown in fig. 4; at this moment, interior stopper 3 is drawing supporting rack 5 through connecting rod 4, and interior stopper 3 is pressing tightly on interior collar 23 under gravity and the inside liquid pressure effect of bottle, and interior stopper 3 forms sealed cooperation with interior collar 23, and the inside liquid of bottle can not continue to get into drain pipe 2, realizes the automatic output of cutting the inside liquid of bottle, can prevent that children from all toppling over out once with the inside liquid of bottle.
