Filtering net device of heat preservation cup

Abstract

The invention discloses a filtering net device of a heat preservation cup. The filtering net device comprises an outer filtering net sleeve barrel, an inner filtering net sleeve and a water floating piece; the inner filtering net sleeve can be slidingly installed in the outer filtering net sleeve barrel up and down, the outer edge of the upper end of the inner filtering net sleeve is provided witha circle of outer boss, the inner wall of the lower end of the outer filtering net sleeve barrel is provided with a circle of inner boss, and the diameter of the inner boss is larger than that of theinner filtering net sleeve and smaller than that of the outer boss; the water floating piece is arranged on the outer wall of the lower portion of the inner filtering net sleeve; the side walls and bottoms of the outer filtering net sleeve barrel and the inner filtering net sleeve are provided with a plurality of filtering holes. When the device is in use, tea leaves are placed into the inner filtering net sleeve, and hot water is poured in for soaking the tea leaves; when the water volume of the heat preservation cup drops to a certain position, since the inner filtering net sleeve is provided with the water floating piece, the inner filtering net sleeve moves upwards relative to the outer filtering net sleeve barrel, most tea leaves in the inner filtering net sleeve are separated from the hot water and cannot be always soaked in the hot water, and micro-substances in the tea leaves cannot be deteriorated due to high-temperature soaking; the filtering net device is reasonable in structure and convenient in tea making.

Description

technical field [0001] The invention relates to the technical field of thermos cups, in particular to a thermos cup filter screen device. Background technique [0002] The thermos cup is generally made of stainless steel, that is, the thermos cup is made of double-layer stainless steel inside and outside. The inner tank and the outer shell are combined by welding technology, and then the air in the interlayer of the inner tank and the outer shell is extracted by vacuum technology. To achieve the effect of vacuum insulation. The middle cover (inner plug body) of some existing thermal water cups is equipped with a filter screen. The existing filter screen generally has two ways of use: ① put the tea leaves under the filter screen, and the function of the filter screen is to prevent the tea leaves from being drunk together with the tea soup. In the mouth, it affects the experience of drinking tea; ② Put the tea on the filter, pour hot water, and brew the tea, which can prevent...

Problems solved by technology

The middle cover (inner plug body) of some existing thermal water cups is equipped with a filter screen. The existing filter screen generally has two ways of use: ① put the tea leaves under the filter screen, and the function of the filter screen is to prevent the tea leaves from being drunk together with the tea soup. In the mouth, it affects the experience of drinking tea; ② Put the tea on the filter, pour hot water, and brew the tea, which can prevent the tea from being boiled by the water in the water cup for a long time; but there are certain differences in the use of these two filters Disadvantages: The first one keeps the tea leaves in the cup, and the water temperature in the warm cup will continue to be high (usually 3-6 hours). If the water and tea leaves are soaked at the same time, the micro-substances in the tea leaves will undergo qualitative changes due to high-temperature boiling. , Drinking too much will be harmful to the body. After a long time, the tea will be stuffy and cooked. The taste of the cooked soup is strong, and the taste of drinking is not good; After drinking a certain amount of tea soup, put the tea leaves on the top and the water on the bottom, the two cannot be mixed together, and the filter must be removed when drinking water, which is troublesome to operate
