Capsule type coffee maker

Abstract

The invention relates to a capsule type coffee maker which comprises a coffee box, a pump, a control valve, a boiler, a water tank, a piston push rod, a return spring, a cylinder, a cylinder fixing seat, a spring seat, a capsule bracket, a guide rod, a bracket spring, a coffee box protection sleeve, a piston rod sealing ring, water outlet silica gel and a water outlet spring. During use, the pump is used for pumping water, the control valve is turned on, and high-pressure water enters a driving water inlet port to press the piston push rod to forwards move so as to jack a capsule into the coffee box until the bottom to ensure that the piston push rod cannot be forwards moved any more; then the pump is used for continuatively pumping water to ensure that the pressure of the whole system is risen to exceed the pressure of a one-way pressure valve formed by the water outlet silica gel and the water outlet spring; the water outlet silica gel is opened, water in the pump flows into a hot water inlet port after being heated by the boiler, and then coffee begins to be extracted; and after the coffee is finished being extracted, the pump is stopped pumping water, the control valve is turned off, and water in the cylinder flows back to the water tank through the control valve under the action of the return spring.

Description

technical field [0001] The invention relates to a coffee machine, in particular to a capsule coffee machine using coffee capsules. Background technique [0002] Capsule coffee machines are widely welcomed because of their features such as no need to grind beans, convenient brewing, consistent taste and quality of brewed coffee. The structure of the capsule coffee machine is different from that of ordinary coffee machines. Generally, a set of clamping mechanism is required to place the coffee capsule, and there are piercing devices at both ends-the piercing needle plate pierces the capsule, and the capsule is injected into the capsule. High-pressure water with a certain temperature can realize the extraction of coffee. The traditional capsule coffee machine uses manpower to squeeze the capsule to complete the sealing process. At the same time, the piercing needle plate can pierce the capsule. This kind of force requires a lot; The pressure of the whole system increases. In ...

AI Technical Summary

Problems solved by technology

[0003] The present invention mainly solves the problems in the prior art that the coffee capsule clamping mechanism is complex in structure, requires a lot of manpower during operation, and the sealing force is small, and at the same time the used capsules are automatically discharged. Squeeze, and the structure is simple, convenient and hygienic. At the same time, it can provide a large sealing force to achieve a good seal, so that it can extract coffee normally without water leakage. The coffee capsule clamping mechanism also uses a single part to realize the automatic discharge of the capsule. Simple and reliable capsule coffee machine
