Technical Field

The invention relates to a beverage preparation machine, in particular to a brewing device, a beverage preparation machine and a beverage preparation system.

Background

The beverage preparation machine is used for preparing beverages required by people, such as tea, fruit juice, vegetable juice, milk tea and the like. Taking the preparation of tea drinks as an example, when people have the requirement of drinking tea, the tea making box with different types of tea arranged inside is placed into the beverage preparation machine, and the people can obtain the brewed tea after waiting for a while.

Chinese utility model patent CN203328516U discloses a beverage preparation machine and beverage preparation system, and the beverage preparation system includes beverage preparation machine and the drink brewing box that uses in coordination. The beverage preparation machine comprises a beverage brewing box placing part, a steering positioning device, a filtering device, a water supply part, a brewing device and a water outlet part, wherein the brewing device is provided with a heating part, a water injection part and a leaching part, and the water injection part is provided with a water injection needle which is connected with the water supply part through a pipeline. The water injection needle is arranged at the position which can be tightly attached to the bottom of the beverage brewing box when the placing part of the beverage brewing box is placed in the beverage preparation machine. The brewing process comprises the following steps: firstly, placing a beverage brewing box into a placing part of the beverage brewing box, then turning a positioning device to drive the beverage brewing box and a water injection part to integrally move towards a filtering device (namely, in the moving process, a water injection needle is always attached to the bottom of a beverage raw material cup), so that the beverage brewing box is positioned between the filtering device and the water injection needle, and when a sealing cover of the beverage brewing box is attached to the filtering device and the bottom is attached to the water injection needle, the turning positioning device continues to drive the beverage brewing box and the water injection part to move for a certain distance, so that the sealing cover and the bottom of the beverage brewing box are simultaneously pressed, the water injection needle punctures the bottom of the beverage brewing box, and water is injected into the beverage brewing box; meanwhile, the puncture head of the filtering device punctures the sealing cover of the beverage brewing box. With the injection of water, the tea leaves are soaked in the beverage brewing box. When the quality of the tea water meets the requirement, the water injection needle continues injecting water, and the brewed tea water is output from the beverage brewing box through the filter holes of the filter device.

Therefore, in the beverage preparation machine, the power for outputting the brewed tea water from the beverage brewing box comes from the water injection of the water injection needle. That is, only when the water injection needle injects water, the tea water can be output from the beverage brewing box; once the water injection stops, the tea water can not be output from the beverage brewing box any more. Therefore, when the brewing is finished, the water injection of the water injection needle is stopped, the tea leaves in the beverage brewing box cannot be separated from the tea water, the tea water is wasted, and the yield of the prepared tea water of the beverage preparation machine is reduced.

In addition, some people like drinking kungfu tea, which means that tea leaves are brewed for multiple times (till), and each tea is drunk. However, only kungfu tea can be brewed manually in the prior art, some people like kungfu tea but can not brew, some people like kungfu tea and can brew, but the brewing process is too complicated. If the kungfu tea is brewed by adopting the beverage preparation machine in the patent CN203328516U, because the tea water in the beverage brewing box cannot be emptied when the water injection of the beverage preparation machine is stopped, the previous tea water remained in the beverage brewing box and the next tea water are mixed together, and the quality of each tea water cannot be ensured. Therefore, the beverage preparation machine in the prior art is only suitable for brewing a large amount of tea water at one time, but not suitable for brewing kungfu tea.

In addition, in above-mentioned drink preparation machine, because water injection device and filter equipment separately set up, and the water injection needle of water injection device corresponds the setting with the bottom of drink raw materials cup, in operation, turn to positioner and not only need remove drink raw materials cup, still need remove water injection device, this has provided higher requirement to the pipeline that is connected between water injection portion and the water supply portion, the overall arrangement of this pipeline is also more complicated, occupied space is bigger, cause the structure of whole drink preparation machine comparatively complicated and the volume is great, be unfavorable for realizing miniaturized target.

In addition, in the beverage preparation machine, since the water injection needle of the water injection device is used for puncturing the bottom of the beverage material cup, and the puncturing head of the filtering device is used for puncturing the sealing cover of the beverage material cup, it is obvious that the sealing cover of the beverage material cup is easier to puncture than the bottom of the beverage material cup. In order to make the water injection needle of the water injection device and the puncture head of the filtering device puncture the beverage raw material cup at the same time by driving the raw material cup to move through the steering positioning device, corresponding puncture schemes need to be designed respectively for two different materials, namely the sealing cover and the cup body, so that the design and manufacturing costs can be increased.
