Self-closed sucker vacuum cup

Abstract

The invention provides a self-closed sucker vacuum cup. The self-closed sucker vacuum cup comprises a cup body, an end socket and an upper cover. The end socket is assembled on the upper portion of the cup body, and a sucker penetrating through the end socket is assembled on the end socket. The sucker comprises an upper section and a lower section, a hinge column vertically penetrating through theend socket is assembled on the end socket, the hinge column and the end socket are rotationally assembled, a communicating block enabling the upper section and the lower section of the sucker to be communicated is assembled on the lower portion of the hinge column, a control rod for pushing the hinge column and the communicating block is assembled on the upper portion of the hinge column, when the control rod is pushed, the communicating block can rotate relative to the sucker, and the upper section of the sucker is directly communicated with the upper portion of an inner cavity of the cup body. Due to the design of the communicating block, the sucker can serve as a water outflow pipe at the same time, in the ventilating process of the air outflow pipe, the sucker can serve as an elasticpart for supporting the upper cover, and the cup is more convenient to use.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, and in particular relates to a self-enclosed straw thermos cup. Background technique [0002] The thermos cup, as the name suggests, usually refers to a cup used to keep the liquid in the cup warm. Traditional thermos cups usually use double-layer or multi-layer materials, or adopt a hollow structure, so that the cup body has better thermal insulation performance. But because the upper opening of the traditional thermos cup is too large, the liquid in the cup communicates with the outside too much, once the cup is opened, it is difficult to maintain the temperature in the cup. Therefore present thermos cup top is usually designed with special closed structure, and these thermos cups can only open a small opening and just make the liquid in the thermos cup flow out conveniently by closed structure. For the convenience of drinking water, some vacuum cups with a closed structure are de...

AI Technical Summary

Problems solved by technology

For the convenience of drinking water, some vacuum cups with a closed structure are designed with a straw structure, but this structure with a straw, in order to make the straw can suck all the drinks in the cup, so the straw on the cup usually extends into the cup. to the lower part of the cup, so that these straws cannot be used to pour out the liquid in the cup, which is not convenient enough to use

In addition, the traditional thermos cup usually only has a simple heat preservation function, and in the specific use process, it is often necessary to cool down the liquid such as tea with a higher temperature in the cup, but the traditional thermos cup is due to heat preservation. The thermal conductivity of the wall is poor, and it is not easy to cool down, which affects people's use
