Description

Electric vacuum tea caddy

Technical Field

The utility model relates to a container for storing and containing tea.

Background

At present, a container for storing and containing tea leaves is generally an iron leather tube, a bamboo tube or a porcelain pot, but in southern areas of China, the tea leaves are easy to go into moisture and mildew due to the fact that the weather is humid, so people put the tea leaves into a refrigerator to prolong the preservation period, but when the tea leaves are taken out, low-temperature objects are easy to agglutinate moisture, the moisture is difficult to avoid, and the tea leaves are difficult to preserve for a long time and only need to be bought frequently.

Disclosure of Invention

In order to overcome the defects, the utility model provides an electric vacuum tea caddy, which aims to prolong the quality guarantee period of tea leaves and ensure that people can drink tea with new tea quality for a long time.

The purpose of the utility model is realized like this: the cover of the tea caddy is made into three layers, the uppermost layer is transparent, a lithium battery, a printed circuit board with a touch switch and a single chip microcomputer and a display screen assembly are arranged between the two layers of the upper side, an electric vacuum pump, a one-way valve, a vacuum switch and an electromagnetic release valve are arranged between the two layers of the lower side, and the cover and the caddy body are sealed by a silica gel pad. When the touch switch on the uppermost layer is touched, the single chip microcomputer on the printed circuit board controls the electric vacuum pump to rotate, air in the tank is pumped out through the one-way valve, and when the vacuum degree in the tank reaches the design requirement, the vacuum switch acts to inform the single chip microcomputer to control the electric vacuum pump to stop running. At the moment, the pot is tightly buckled due to atmospheric pressure, and the silica gel pad is arranged between the pot body and the cover, so that the pot can be kept airtight for a long time, and the vacuum storage of the tea leaves is realized. When tea needs to be taken, the touch switch can be pressed for 2 seconds, the singlechip on the printed circuit board controls the electromagnetic air release valve to release air into the tank, and the tank is easy to open due to the disappearance of the vacuum degree in the tank. After the tea leaves are taken, the cover is buckled, the touch switch is pressed, the single chip microcomputer controls the electric vacuum pump to rotate, the actions are repeated, and the vacuum state is recovered in the tank.

Because the volume in the tank is smaller, the requirement on the vacuum degree is not high (negative pressure is 40KPa), the lithium battery is fully charged, the vacuum and the air release can be carried out for more than one hundred cycles, and if the tea is frequently drunk, the lithium battery is charged once every quarter.

The utility model discloses main technical characteristics of claim are: a lithium battery, a display screen and a printed circuit board are fixedly connected above the upper support, and a one-way valve, an electromagnetic deflation valve, a vacuum pump, a micro motor and a vacuum switch are fixedly connected between the upper support and the lower support; the vacuum pump is fixedly connected with the micro motor in a coaxial mode, one end of a first silicone tube is in through connection with a small tube head on the lower support, the other end of the first silicone tube is in through connection with an air inlet of the vacuum switch, one end of a second silicone tube is in through connection with the small tube head on the lower support, the other end of the second silicone tube is in through connection with an air outlet of the electromagnetic release valve, one end of a third silicone tube is in through connection with the small tube head on the lower support, the other end of the third silicone tube is in through connection with an air inlet of the one-way valve, one end of a fourth silicone tube is in through connection with the air outlet of.

The utility model discloses a secondary technical feature who claims is: the lithium battery is electrically connected with the printed circuit board, the electromagnetic air release valve is electrically connected with the printed circuit board, the micro motor is electrically connected with the printed circuit board, the display screen is electrically connected with the printed circuit board, and the vacuum switch is electrically connected with the printed circuit board.

The utility model has the advantages that: the shelf life of the tea is improved by eight to nine times compared with the normal storage, and a user can drink tea water with the quality of new tea for a long time.
