Brewing device of coffee powder bag

Abstract

The invention discloses a brewing device of a coffee powder bag, which can automatically discharge and collect the used waste powder bags and is convenient for use. The brewing device comprises a barrel (1), a coffee outflow piece (2), a front brewing piece (3), a rear brewing piece (4), a rocker arm (5) and a connecting arm (6), wherein a charging hole (11) is arranged above the barrel (1), and a discharging hole (12) is arranged below the barrel (1); the charging hole (11) and the discharging hole (12) are staggered with a certain distance in the axial direction; the front brewing piece (3) and the rear brewing piece (4) are both positioned at the inner chamber of the barrel (1), and are connected with the barrel (1) in a sliding manner in the axial direction; the rocker arm (5), the connecting arm (6) and the rear brewing piece (4) together compose a slider-crank mechanism; the front brewing piece (3) and the rear brewing piece (4) are connected by at least two sliding rods (7) on the side wall; the sliding rod (7) is sheathed with a compression spring (8) which separates the front brewing piece (3) from the rear brewing piece (4) with a certain distance; and the clearance between the front brewing piece (3) and the rear brewing piece (4) corresponds to the charging hole (11).

Description

technical field [0001] The invention relates to a coffee brewing device, in particular to a brewing device when coffee powder is prepackaged as a coffee powder bag (COFFEE POD). Background technique [0002] Coffee powder pack (COFFEE POD) is a prepackaged form of coffee powder. At present, there are mainly two types of devices for brewing coffee powder packets. One is a traditional pressure coffee pot. For example, the Chinese national patent No. ZL 200520064857.6, titled "A coffee powder bag brewing device for a coffee machine" is such a brewing device. The upper punch on the main body of the machine is connected to the brewing water supply pipeline, and the lower punch cooperates with the upper punch to form a brewing cavity and is connected to the coffee output part. The upper punch and the lower punch are paired with a screwing mechanism. This device operates It is laborious and troublesome to clean, and the used waste toner bag cannot be automatically discharged and ...

One is a traditional pressure coffee pot. For example, the Chinese national patent No. ZL 200520064857.6, titled "A coffee powder bag brewing device for a coffee machine" is such a brewing device. The upper punch on the main body of the machine is connected to the brewing water supply pipeline, and the lower punch cooperates with the upper punch to form a brewing cavity and is connected to the coffee output part. The upper punch and the lower punch are paired with a screwing mechanism. This device operates It is laborious and troublesome to clean, and the used waste toner bag cannot be automatically discharged and collected. The used waste toner bag must be removed manually, and each time a toner bag is brewed, it needs to be cleaned once, which is inconvenient for users to operate

Another machine for brewing coffee powder pods is a device driven by a complex structure, such as the PCT international patent with the publication number WO2009 / 010997 and the name "IMPROVEMENT OF ESPRESSO COFFEE DISPENSING MACHINESUSING SINGLE-DOSE GROUND COFFEE PODS" The application is the latest device for brewing coffee powder packs. Although this device solves the problem of effectively compressing the coffee powder packs, it still does not solve the problem of automatically discharging and collecting used waste powder packs.

[0003] Therefore, the existing technology has the following deficiencies: the used waste toner bag cannot be automatically discharged and collected, and it is inconvenient to use
