Abstract

A coffee machine waterway constant flow and constant pressure valve comprises a valve body. The valve body is sleeved with a membrane. A water chamber cavity is formed between the valve body and the membrane. A water inlet hole and a water outlet hole are formed in the valve body. The two ends of the valve body are connected with a valve deck and a valve bushing respectively. A pipeline is arranged inside the valve body. The valve deck is connected with the valve bushing in a fastened mode. An air chamber cavity is formed between the valve deck and the membrane. When an electromagnetic pump works, water flows into the water chamber cavity through a pipeline from the water inlet hole, and the membrane will generate response deformation along with work of the electromagnetic pump. Water is buffered and energy is stored inside the water chamber cavity, the flow and pressure of the pipeline are kept constant to be invariable, and then the water enters the pipeline of the valve deck through the water outlet hole and flows into a follow-up waterway system through a joint of the valve bushing. Noise generated in the overall water pumping process is quite small, the flow and pressure of the waterway are kept constant to be invariable, and the extracted espresso quality is quite high.

Description

technical field [0001] The invention relates to a constant-current and constant-pressure valve, in particular to a constant-current and constant-pressure valve for a waterway of a coffee machine, which belongs to the technical field of coffee machines. Background technique [0002] In the fully automatic or semi-automatic pressure coffee machines currently on the market, the pressure required for extracting coffee is provided by an electromagnetic pump. When extracting coffee, the water has to overcome the resistance of the coffee powder and the pressure check valve device in the brewing chamber. During the coffee making process, the performance of the water pump will attenuate, especially when the coffee powder is too fine. Bigger, faster decay, less water flow, and less line pressure for espresso extraction. Chinese Patent Document No. CN103565277A provides a coffee machine and its working method, including a hydraulic brewer and a one-way valve, the hydraulic brewer is p...
