Clamping mechanism of beverage preparation device

Abstract

The invention relates to a clamping mechanism of a beverage preparation device, comprising a base frame, a first machine element and a second machine element. The clamping mechanism is characterized by also comprising a clamping plate, a driving bracket and a tension spring, wherein the clamping plate is positioned in right front of the second machine member and can laterally slip relative to the front end face of the second machine member; a connecting foot extending backward is arranged at the rear part of the clamping plate, and movably passes through and extends out of the second machine member; the driving bracket is positioned in rear part of the second machine member and can laterally move relative to the second machine member; the lower part of the second machine member is connected with the connecting foot extending out of the rear end face of the second machine member; the base frame is provided with a shift structure matched with the driving bracket; and the tension spring is connected between the driving bracket and the base frame and acts on the driving bracket and the clamping plate to enable the clamping plate to keep the trend of attaching to the front end face of the second machine member. The clamping plate is attached to the front end face of the second machine member and clamps an annular space ring of a beverage bag so as to clamp the beverage bag.

Description

technical field [0001] The present invention relates to a package mechanism of a beverage preparation device, wherein beverage preparation materials such as roasted and ground coffee, instant coffee, tea or other dehydrated products are packaged in a sealed beverage bag similar to a jelly bag. Background technique [0002] The traditional components of existing beverage preparation devices such as coffee machines generally include water tanks, heating elements, and water pumps. For the convenience of portability, various types of coffee such as roasted and ground coffee, instant coffee, etc. are packaged in a sealed similar jelly bag. When in use, put the coffee bag containing the coffee in the coffee machine, and then pump the heated water into the chamber where the coffee bag is placed in the coffee machine. The water flows through the raw materials to be extracted, such as coffee, to heat The coffee flows from the spout of the coffee machine into the cup. After use, it i...

Problems solved by technology

[0005] The aforementioned coffee machine is not equipped with a special bag clamping mechanism, and this coffee machine is only suitable for extracting coffee bags with a certain thickness and weight. After being inside the concave cavity, the inner wall of the concave cavity has a supporting effect on the coffee bag. When the second mechanism is turned over, the coffee bag is not easy to fall out of the concave cavity

But if it is a coffee bag of non-woven fabric or filter paper type, the periphery of this coffee bag has a soft annular spacer, and this coffee bag is light in weight and thin in thickness. In the concave cavity, the contact area between the coffee pod and the inner wall of the concave cavity is small. When the second part is turned over, the coffee pod is easy to fall off from the concave cavity due to the vibration of the second part, which affects the normal use of the coffee machine. , such as the patent No. ZL94193279.6 (announcement number is CN1130345Y) Chinese invention patent "packaging of quantitative bagged ground coffee and pressure coffee machine using this packaged coffee" just discloses non-woven fabric or filter paper type coffee Bag
