Lift tube protecting drainage cover, lift tube module and beverage production machine

Abstract

The invention relates to beverage production machines and particularly provides a lift tube protecting drainage cover, a lift tube module and a beverage production machine. The anti-scald device of anexisting beverage production machine is composed of electronic elements to result in manufacturing complexity and corrosion proneness. The lift tube protecting drainage cover and the lift tube moduleserve as a simple substitute part of the anti-scald device. The beverage production machine comprises a cover, a container, a brewer and a liquid pump, wherein the liquid pump pumps liquid inside thecontainer to the brewer through a lift tube, and the water outlet of the lift tube is provided with the lift tube protecting drainage cover which is also provided with a water outlet; the cover is provided with a downwards extending protruded part. Only when the cover is closed, the lift tube protecting drainage cover can be triggered by the protruded part to open the water outlet, thereby ensuring no liquid ejected from the beverage production machine when the cover is open, further simply achieving protecting effects and avoiding disadvantages of the electronic elements, increasing the spray coverage area of filling water into the brewer, and improving the brewing effects.

Description

technical field [0001] The invention relates to a beverage making machine, and specifically provides a protective drainage cover for a liquid riser, a liquid rising pipe assembly including the protective drainage cover, and a beverage making machine. Background technique [0002] In the process of brewing beverages with automatic beverage making machines, the pumping device is usually required to pump the liquid from bottom to top. If the lid is not closed properly, the liquid is easily ejected from the beverage making machine and splashed on the operator. Or deface the surrounding environment, and many beverage makers have a heating function, which may cause burns if the jet is hot fluid. [0003] CN104161462B is the applicant's Chinese invention patent, which discloses an anti-scald device for a drink making machine. The pump, the riser assembly and the sunken cavity together form a pumping unit that transports the cold or heated liquid in the container to the brewer via ...

Problems solved by technology

[0004] However, the anti-scald sensor is an electronic device, which is complicated to manufacture. It is easily corroded or aged in the hot steam environment with different acid and alkali for a long time, and has a short service life and is not easy to maintain.

In addition, if the brewing liquid is poured into the brewer in one bundle through the riser tube, the spraying range is too concentrated, and it does not take as little time as possible to wet as much as possible of the brewing ingredients to make it evenly absorb water, which is not suitable for some very light The brewing seasonings (such as herbal plant seasonings) are easy to float on the liquid surface and cannot be fully soaked. For some powdery seasonings that are not instant soluble, it is easy to make them cluster and cannot be well dissolved in the brewing liquid, thus affecting the brewing process. bubble effect
