A drip coffee machine

Abstract

A hourglass type coffee machine comprises a water box, a base and a hopper assembly, wherein a heating assembly is arranged in the base and is connected with the hopper assembly through the water box in a supporting mode, the size of the hopper assembly is smaller than that of the water box, and the hopper assembly and the water box contain each other in a telescopic or folding or folding and assembling mode so that the size of the coffee machine can be reduced. According to the hourglass type coffee machine, a rotary telescopic rod is arranged between the water box and the hopper assembly, the water box and the hopper assembly are rotationally connected through the rotary telescopic rod and contain each other in a mode that an inner pipe is sleeved with an outer pipe, one side of the water box is provided with the outer pipe, water outlet pipes are arranged in the hopper assembly and the outer pipe respectively, and the water outlet pipes are connected in a sealed mode and contain each other in the same mode. A user only needs a series of actions of rotating, sliding sleeve stretching and retracting and containing, the size of the coffee machine can be reduced by nearly one half, the package size is greatly reduced, the loading number is increased, and therefore transportation cost is lowered. Damage risk of the hourglass type coffee machine in a transportation process can also be reduced, and the user carries, uses and stores the hourglass type coffee machine conveniently.

[0002] Chinese Patent Document No. CN202269897U disclosed a drip coffee machine on June 13, 2012, which includes a water tank, a water pipe, a water heating pipe, a water heating device, an upper water pipe, and a funnel for accommodating coffee powder. A water injection port is provided, the lower water pipe, the water heating pipe and the upper water pipe are connected, and the upper end of the lower water pipe is connected with the water tank, and the upper end of the upper water pipe is located above the funnel, and the lower water pipe and the upper water pipe are equipped with a One-way valve, the water tank is also provided with a funnel bracket for accommodating the funnel, an elastic bag is arranged in the water tank, the lower end of the funnel is located in the opening at the top of the elastic bag, and the top edge of the elastic bag is sealed with the inner wall of the water tank fit; the side wall above the water tank is provided with a water outlet, and the water outlet communicates with the inside of the elastic bag; the water tank, funnel and water heating device of this structure each occupy a certain volume, and the overall size of the coffee machine is large Depends on the capacity of the funnel; taking the above structure as an example, the size of the smallest cup of coffee machine can only be about 19CM. This structure determines that this size can no longer be reduced. Therefore, it increases the cost of production, packaging and transportation of the product , and it is not convenient for users to carry outdoors, and the scope of use is small
