Coffee Machine High Pressure Funnel Lost Wax Castings

Product Introduction

The utility model relates to the technical field of coffee machines, in particular to a coffee machine high-pressure funnel device and a coffee machine.

Background technique

The coffee machine generally adopts an instant boiler with a pressure relief box device. Before brewing coffee, there will be a program to pump the water to relieve the pressure; while the coffee high-pressure funnel device commonly used on the pressure coffee machine can only be used within the coffee preheating temperature point. The hot water can make coffee normally. When the water temperature exceeds the pressure relief device in the coffee machine, the pressure relief device in the coffee machine must be used to pump cold water to release the pressure and drain the temperature before making coffee. If the coffee is not cooled down, overflow will occur at the funnel device. The coffee will flow out of the device, and in extreme cases, splashing will occur. There is a safety hazard of scalding the user, and the coffee cannot be brewed normally. The applicant once proposed a high-pressure funnel device for a cn201855126u coffee machine, including a high-pressure funnel with a filter screen on it, and the filter screen is pressed tightly on the high-pressure funnel through a sealing ring, and the three form a closed cavity for coffee extraction. There is a transitional fit between the funnel and the filter and an interference fit between the filter and the sealing ring. After the coffee is extracted, it falls into the high-pressure funnel. During this period, the coffee liquid will boil due to excessive steam, and the coffee will not flow smoothly.

In order to realize that when the temperature of the hot water exceeds the coffee preheating temperature, the coffee machine does not need to release pressure and drain to cool down, and can directly use this device to brew coffee without coffee overflowing and splashing, so that it can be used under overheating conditions. For the normal brewing of coffee, the applicant made a further improvement and proposed the following technology.

Technical Realization Elements

In view of this, the utility model provides a coffee machine high-pressure funnel device, and a coffee machine.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a coffee machine high-pressure funnel device, including: a high-pressure funnel and a coffee filter, the coffee filter is assembled at the opening of the high-pressure funnel, and forms a container between the high-pressure funnel cavity; the bottom of the high-pressure funnel forms a liquid outlet; it also includes a funnel stopper; the funnel stopper is assembled in the cavity, and the funnel stopper is provided with at least one baffle protruding toward the opening direction of the high-pressure funnel, and the bottom of the funnel stopper A coffee outlet is provided, and the coffee outlet communicates with the liquid outlet;

When brewing coffee, high-pressure water flows through the coffee filter for coffee extraction, and the coffee flows into the cavity through the coffee filter. Because of the high-temperature and high-pressure water flow, the coffee liquid is sprayed out from the bottom of the coffee filter along with the steam, and the coffee When the liquid and steam come to the funnel block, they will be fully buffered and then stay in the two coffee outlets of the funnel block. During this period, the coffee liquid will boil due to excessive steam. At this time, the block plays a blocking role. The coffee liquid is buffered so that the coffee liquid can flow into the coffee cup smoothly, completing the process of brewing coffee smoothlys, and avoiding the rapid splashing of the coffee liquid from the groove and the phenomenon of overflow.

In a further technical solution, the bottom of the funnel block forms a sealing part, which is adapted to the inner wall of the high-pressure funnel, and the shape of the funnel block roughly matches the shape of the bottom of the high-pressure funnel. The assembly structure is compact and can ensure The coffee liquid falls into the funnel cover after passing through the coffee filter and flows out through the coffee outlet.

The funnel block is in the shape of a funnel as a whole, and the block is in the shape of a convex ring. The shape of the funnel block is defined to match the shape of the high-pressure funnel, and the installation is more compact, while the shape of the block is defined to When the coffee boils and splashes, it can be blocked and buffered by the stopper to ensure smooth coffee dispensing. Of course, the stopper can adopt other shapes.

There are two baffles concentrically arranged at the center of the bottom of the funnel baffle, which limits the number and specific positions of the baffles. Since the funnel baffle is funnel-shaped, when the coffee liquid flows downward, it gathers at the bottom of the high-pressure funnel, because the blocking part is arranged at the center to play a better blocking effect and buffer the coffee liquid.

The bottom of the funnel block forms a diversion column, and the coffee outlet is formed in the diversion column; the diversion column is inserted into the liquid outlet, and the diversion column makes the funnel block better assembled in the high-pressure funnel, and at the same time guides the coffee flow out.

A groove is formed between the funnel block and the inside of the high-pressure funnel.

The edge of the coffee filter is bent and set, supported on the top of the high-pressure funnel, and the bottom of the coffee filter is provided with a double-layer filter, and the coffee brewing effect of the double-layer filter is better.

A coffee machine includes a body, on which a high-pressure funnel device of the coffee machine is detachably assembled, and the coffee machine has better performance and better competitiveness in the market.
