Environment-friendly tea cup

Abstract

The invention discloses an environment-friendly tea cup, which is used for accommodating hot water without pollution to the water therein due to the occurrence of a chemical reaction. The environment-friendly tea cup is composed of a cup cover, a cup body and a sealing pad, wherein a cylindrical hollow core body is arranged in the cup cover, and a screw thread is arranged on the side face of the cylindrical hollow core body; big and small cylindrical hollow core bodies are arranged in the cup body; an annular part where the bottom end of the outer side of the small cylindrical hollow core bodyis crossed with the big cylindrical hollow core body is provided with the sealing pad; a screw thread is arranged at the outer side of the small cylindrical hollow core body, and the screw thread isconnected to the screw thread in the cup cover; and the sealing pad is arranged on a threaded part where the cup body and the cup cover are connected. When the tea cup is used, leakage of the water inthe cup can be prevented as the cup cover is screwed up and the cup cover and the sealing pad in the cup body are clamped under the effect of a screw; by arranging the sealing pad at the outer side of the cup body, the chemical reaction can be prevented even the water in the cup is too hot; and the chemical reaction, under the water temperature within a time period that the sealing pad gets intocontact with the water due to shaking of the cup, can be prevented.

Description

technical field [0001] The invention relates to a teacup device for drinking water, in particular to an environment-friendly teacup for holding hot water without causing chemical reaction to pollute the water in the cup. Background technique [0002] At present, existing thermos cups or other types of cup lids are made of materials such as environmentally friendly rubber or plastic or stainless steel, but the problem is that these materials are reusable such as plastic and stainless steel, and no matter how environmentally friendly plastic meets Chemical reactions will occur more or less at high temperatures. Although rubber cannot be reused, adulteration is serious. If there are environmental protection materials and non-environmental protection materials mixed, it is also harmful to the human body. Although stainless steel is environmentally friendly and used The time is also long, but the gasket in it is made of rubber material, and these materials contact with freshly bo...

Problems solved by technology

[0002] At present, existing thermos cups or other types of cup lids are made of materials such as environmentally friendly rubber or plastic or stainless steel, but the problem is that these materials are reusable such as plastic and stainless steel, and no matter how environmentally friendly plastic meets Chemical reactions will occur more or less at high temperatures. Although rubber cannot be reused, adulteration is serious. If there are environmental protection materials and non-environmental protection materials mixed, it is also harmful to the human body. Although stainless steel is environmentally friendly and used The time is also long, but the gasket inside is made of rubber material. These materials are in contact with freshly boiled water for a long time. No matter how environmentally friendly the material is, some chemical reactions cannot be avoided, which will also be harmful to the human body.
