Description

Vacuum tea maker and vacuum tea maker with pre-evacuation device

The present invention relates to a tea-making machine, especially a vacuum tea-making machine and a vacuum tea-making unit with a pre-evacuation device.

Drinking a pot of good tea for drinking is a habit for many people. Since most people live fast, they often lack time. As a pot of good tea is brewed, it usually takes 5-6 minutes to brew the tea, so that the aroma of the tea can be completely dissipated and provide a good tea with delicious sweetness. In order to make it easy for people to drink good tea, tea machines are currently on the market. The tea machine provides people with hot water into the brewed tea leaves. Or, the tea machine is equipped with a heater for the tea machine. The water in the water storage container is heated to make tea, and after the tea leaves are soaked in the hot water occupying the water storage container, people can provide tea for drinking.

However, the above-mentioned existing tea brewing system brews tea under general air pressure. During the short tea brewing process, the essence components in the tea leaves are difficult to be effectively extracted, and the aroma in the tea leaves is not easy to completely disperse. Therefore, some tea brewing machines are A vacuum pumping device is further added to perform the vacuum pumping action when the water storage container is brewing tea. Under the vacuum state, the tea leaves are soaked in hot water during the brief tea brewing process, and the essence components in the tea leaves can be extracted more, and the tea leaves The aroma in it is easier to spread, allowing people to drink good tea with a strong tea aroma.

However, the existing vacuum tea brewing machine is a machine that combines a tea brewing device and a vacuum pumping device, and its overall weight is heavier, which is inconvenient for users to use and operate. Moreover, each vacuum tea maker must be continuously evacuated by the vacuum evacuation device for a period of time to evacuate the air in the water storage container of the tea cooked device, which is time-consuming to use. For tea shops, due to the needs of commercial implementation, multiple sets of vacuum tea machines need to be used simultaneously or alternately, so there is a problem of high equipment cost.

The purpose of the new model is to provide a vacuum tea machine and a vacuum tea machine unit with a pre-evacuation device, to solve the time-consuming operation of the existing vacuum tea machine, and the equipment cost of each group of vacuum tea machine needs to have a vacuum device Higher issues.

In order to achieve the foregoing purpose, the vacuum tea maker with a pre-evacuation device proposed by the present invention includes: a pre-evacuation device, which includes: an airtight chamber with a closed chamber, and can be pre-evacuated A negative pressure state is generated; a first switch valve is installed on the airtight cavity and can switch the switch state of the closed chamber to the outside; a second switch valve is installed on the airtight On the cavity, and can switch the closed state of the closed chamber to the outside; and a connecting pipe, which is connected to the second on-off valve; and at least one tea-making device, which is detachably connected to the pre-evacuation device, and It includes a housing, an airtight container that can be opened and closed, and a control assembly. The airtight container and the control assembly are disposed in the housing. The top of the airtight container has a suction port, and the suction port can be connected to the The connecting pipes of the pre-evacuation device are detachably connected. The bottom of the airtight container has a switchable water outlet controlled by one of the control components.

In order to achieve the foregoing objective, the vacuum tea maker set proposed in the present invention further includes: at least one vacuum tea maker as described above; and A vacuum pumping device is detachably connected to the first switching valve of the pre-pumping device, and can pre-pump the airtight cavity.

Through the creation of the aforementioned vacuum tea maker and vacuum tea brewing unit, the pre-evacuation device can be connected to a vacuum exhaust device, so that the airtight cavity of the pre-evacuation device is pre-evacuated through the vacuum exhaust device to form a near vacuum After the negative pressure state is closed, the connection relationship between the pre-evacuation device and the vacuum pumping device can be removed, so that the pre-vacuum device is in a negative pressure state close to vacuum for standby, so, by pre-evacuation The vacuum device and the vacuum pumping device are detachable external connection relationships. The vacuum pumping device is placed outside the pre-vacuum device, so the pre-vacuum device can be connected to the tea brewing device after pre-vacuuming. Excellent portability.

Furthermore, when the user wants to use the tea brewing device to brew tea, he can connect the airtight container of the tea brewing device with a portable pre-evacuation device to make the airtight container filled with tea leaves and hot water. The vacuum state is reached, so that the tea leaves in the hot water can quickly and completely release their tea fragrance, shorten the time for brewing tea, and improve the quality and aroma of the tea water cooked under the vacuum state, so that the user can experience the rich tea aroma and thick The taste of tea soup.

The airtight cavity system of the pre-evacuation device in the new vacuum tea maker and the vacuum tea-making unit is pre-evacuated to a high negative pressure vacuum state. When the pre-vacuum device is connected to the tea brewing device through the connecting pipe After the airtight container, it can quickly reach the predetermined vacuum state, shorten the operation time of the airtight container vacuuming of the tea brewing device, and improve its use efficiency.

When the vacuum tea maker and vacuum tea maker are used in commercial implementation, the tea brewing device is multiple, and a single lightweight pre-evacuation device can quickly and easily pump the airtight container of the multiple tea brewing devices The action of vacuum, and the pre-evacuation device is portable and easy to use and operate, improving the convenience of its commercial implementation and reducing equipment costs.

The airtight cavity of the pre-vacuum device of the vacuum tea maker and the vacuum tea brewing unit can be additionally provided with a vacuum pressure gauge connected to the closed chamber, and the closed chamber is displayed by the vacuum pressure gauge The vacuum pressure value is convenient for the user to operate the pre-evacuation of the airtight chamber to a high negative pressure vacuum state, and when the vacuum pressure value of the closed chamber is insufficient, the airtight chamber can be timely connected to the vacuum pumping device for Pre-evacuate.
