Coffee maker without water tank

Abstract

The invention relates to a coffee maker without a water tank, comprising a heating device arranged inside a maker body; the water outlet end of the heating device is connected with a brewing head arranged above a funnel through a water outlet pipe, and the water inlet end of the heating device is connected with the water outlet end of a valve through a pipeline assembly; a water bottle base capable of placing a replaceable water bottle is arranged at the upper part of the maker body, and the water bottle base is connected with the water inlet end of the valve; the water bottle base is provided with an inner cavity connected with a pipe joint, and the water bottle is inversely buckled and connected to the water bottle base; a leakproof valve is arranged in the pipe joint, a leakproof seal ring which is capable of sealing a water outlet nozzle is sleeved on the upper end of the leakproof valve, and the lower end of the leakproof valve is connected with the water outlet nozzle through a spring. The coffee maker of the invention adopts the replaceable water bottle for supplying water instead of the traditional water tank and is not limited by the volume of the water tank in a using process; different volumes of water bottles can be replaced as required, therefore, the size of the maker body is greatly reduced; and the coffee maker provided by the invention has the advantages of convenience for carrying, small storage space, low transportation cost and convenience for operation.

Description

Technical field [0001] The invention relates to a coffee machine, in particular to a water tankless coffee machine. Background technique [0002] The coffee machine in the prior art has a water tank on its body. When in use, a certain amount of water is added to the water tank, coffee powder is put in the funnel, and the coffee is started. For example, Chinese Patent Document No. CN101404916 disclosed a drip coffee machine on April 8, 2009, which includes features that improve the taste of brewed coffee and promote use. In one embodiment, the integrated plate and disc grinder provides coffee powder into the coffee chute, which sends the material to the filter cone. The slide door at one end of the coffee slide prevents steam or condensate from entering the coffee slide. In another embodiment, the ejection tray with the filter cone may be coupled with a damped spring biasing mechanism that moderates the ejection movement. Further, the rotating buoy can be provided in the carafe...

AI Technical Summary

Problems solved by technology

Since the maximum capacity of a coffee machine with a water tank is rated, if a large-capacity water tank is used, the body of the coffee machine will be relatively large, which is generally not easy to carry, and it will take up a lot of space when stored, and the transportation cost is relatively high. Moreover, the water tank generally needs to be cleaned regularly, which is very inconvenient to operate.
