AI Technical Summary
The water-controlled components of existing pneumatic coffee machines cannot isolate water, limit water flow, change the direction of water flow and slow down the impact force of water flow, resulting in poor quality of coffee extraction, easy blockage of structure and inconvenient use.
A water control component including a flow limiting valve, drainage pipe, water partition plate, shunt valve and water distribution network is designed. The flow limiting valve is externally installed to prevent blockage. The shunt valve disperses the water flow, and the water partition plate isolates the water from the sealing rubber gasket. , realizes water flow control and gentle distribution.
It achieves uniform extraction of water, prevents powder from rupturing, reduces the risk of use, facilitates cleaning and maintenance, and ensures efficient operation of the coffee machine.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of coffee, in particular to a water control component of a pneumatic coffee machine. Background Art
[0002] When extracting coffee, the flow rate and flow control of water play a vital role in the quality of coffee. Strictly speaking, only semi-automatic coffee machines can be called professional coffee machines. For small and portable pneumatic coffee machines, there are limitations in size and structure. It is not compatible with the water control parts of multiple coffee machines. The water control parts used in existing pneumatic coffee machines on the market include one-way valves, food-grade silicone pads, flow limiting valves, water diversion nets, etc. The above cannot simultaneously meet the functions of isolating water, limiting water flow, changing water flow direction, and reducing water flow impact. Summary of the invention
[0003] The purpose of the utility model is to provide a pneumatic coffee machine water control component to solve the problems raised in the above background technology.
[0004] To achieve the above purpose, this utility model integrates the idea of water flow control of the coffee machine into a small component. The following technical solution is provided: including a flow limiting valve, one end of the flow limiting valve is connected to a drainage tube, the other end of the drainage tube is connected to a diversion valve, the drainage tube is connected to a water baffle, the side of the water baffle has a sealing rubber pad, and the water baffle is connected to a water diversion network. The beneficial effects of the utility model are as follows:
[0005] 1. The drainage tube and water baffle in this solution replace the one-way valve of most pneumatic coffee machines on the market, which can isolate water when there is no pressure and will not wet the powder cake in advance. And it is not like a one-way valve that cannot reverse pressure relief, and can keep the pressure of the water tank and the brewing head consistent.
[0006] 2. If the diameter of the small hole on the flow limiting valve is 0.6 mm, it can limit the amount of water entering, increasing the time required to wet the powder cake. The more completely the powder cake is wetted, the more uniform the extraction will be. At the same time, when the extraction is about to end, the small hole of the flow limiting valve can limit the flow rate at the end, achieving the purpose of reducing the pressure at the end.
[0007] 3. Compared with the current limiting valve on the market, the current limiting valve in this solution is not installed inside the coffee machine. This design places the current limiting valve on the outermost side of the entire structure because the small hole diameter of the current limiting valve is 0.5 mm, 0.6 mm, 0.8 mm, etc., which is easily blocked by scale or coffee powder. It can be checked before use. If there is a blockage, it can be unblocked with tools at any time without disassembling the coffee machine. It also reduces the risk of use.
[0008] 4. In this solution, there are oval-shaped extended small handles on both sides of the flow limiting valve, which are easy to hold and replace without using tools.
[0009] 5. In this solution, the diverter valve disperses the concentrated water flow to different directions through the small holes on the side, making the water flow softer, avoiding the impact of the water flow on the middle of the coffee powder cake, and retaining the integrity of the coffee powder cake to the greatest extent.
[0010] 6. The water control component of a pneumatic coffee machine in this solution is a free end, which is easy to use and can be cleaned at any time without disassembling the coffee machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Embodiment 1, please refer to Figures 1-6. The utility model provides a technical solution. The water-dividing net 6 is placed directly in the powder bowl filled with coffee. The water-blocking plate 4 and the sealing rubber pad 5 isolate the water and the coffee powder. When the water is extracted by external pressure, for example, the pressure is set at 3 bar or 9 bar, the water passes through the flow-limiting valve 1, and the inner diameter of the small hole is set at 0.6 mm. The water output at a fixed time can be controlled, and then reaches the drainage pipe 2. The drainage pipe 2 has a certain length. In the absence of pressure, the water cannot contact the coffee powder. Next, the water reaches the diverter valve 3, and the water is dispersed to different directions from the small holes of the diverter valve 3. The purpose of the diverter valve is to make the water flow soft and avoid the cracking of the coffee powder in the middle due to the impact of high pressure. Finally, the water penetrates into the coffee powder through hundreds of small holes of the water-dividing net 6, thereby achieving the purpose of extracting coffee.
