Piercing mechanism and beverage brewing device

Abstract

The invention provides a piercing mechanism and a beverage brewing device. The piercing mechanism comprises a main body as well as a piercing component and a funnel component which are arranged on themain body, and further comprises a motor and a gear which is connected to the motor by virtue of a shaft, wherein the piercing component comprises a piercing needle; the funnel component comprises acapsule which is arranged under the piercing needle and a lower piercing needle which is arranged under the capsule; the piercing component further comprises a gear rack which is meshed with the gear,and the piercing needle is arranged under the gear rack; when the shaft, which is driven by virtue of the motor, rotates in a positive direction, the piercing needle is driven to move downwards by virtue of the gear rack, the capsule is pierced by virtue of the piercing needle and the capsule is driven to move downwards and is pierced by virtue of the lower piercing needle; or when the shaft, which is driven by virtue of the motor, rotates in a negative direction, the gear rack moves upwards, and the piercing needle is driven to move upwards and away from the capsule. The piercing mechanism provided by the invention has the beneficial effects that the capsule can be pierced through cooperation of the gear and the gear rack, and the capsule, which is uniformly stressed, cannot get burst easily; and the piercing mechanism is simple in structure and reliable in control.

Description

technical field [0001] The invention relates to the field of white household appliances, in particular to a piercing mechanism and a beverage brewing device. Background technique [0002] The existing K-CUP beverage brewing device is generally manually pressed to assist in puncturing the capsule containing the beverage powder, and the brewing water is pressed into the capsule to obtain a beverage. For example, U.S. Patent US6606938 B2 discloses a single-cup beverage brewer, which includes a capsule, a tubular water outlet needle arranged at the bottom of the capsule, and a pressure plate with an elastic device. The disc moves up and down, the water outlet needle pierces the water outlet end of the capsule and then the water inlet needle pierces the water inlet end of the capsule. The structure of the brewing device has high requirements on the hardness of the capsule. If the capsule shell is soft, the capsule shell cannot be pierced by a needle, resulting in beverage failur...
