Description

Technical Field

[0001] The utility model relates to the technical field of coffee machine equipment, in particular to a multi-boiler coffee machine with adjustable pressure. Background Art

[0002] A multi-boiler coffee machine is a professional-grade coffee machine, usually used in high-end coffee shops or coffee lovers' homes. Unlike a single-boiler coffee machine, a multi-boiler coffee machine is equipped with multiple independent boiler systems, each of which is responsible for controlling water at different temperatures, usually used to provide coffee, steam and hot water respectively, making it possible to more accurately control the water temperature when making different types of coffee, thereby ensuring the quality and taste of the coffee.

[0003] However, ordinary coffee machines do not have an automatic pressure adjustment system. Users need to manually control the water flow and water pressure, which may require certain experience and skills and is not suitable for ordinary users or beginners. Traditional coffee machines may lack a sophisticated water control system, resulting in the inability to accurately control the water flow and water pressure, which may affect the taste and quality of the coffee. Utility Model Content

[0004] In view of the above problems, the utility model provides a multi-boiler coffee machine with adjustable pressure, which effectively solves the problem that ordinary coffee machines require users to manually control water flow and water pressure.

[0005] The utility model adopts the following technical scheme: a multi-boiler coffee machine with adjustable pressure, comprising a boiler without a heat exchanger, an L-shaped joint is arranged on one side of the boiler without a heat exchanger, one end of the L-shaped joint is connected to a solenoid valve through a water pipe, one end of the solenoid valve is connected to a single-head distributor through a water pipe, one end of the single-head distributor is arranged with a one-way valve, one end of the one-way valve is connected to a water pump through a water pipe, one end of the water pump is connected to a water inlet pipe through a water pipe, one side of the water inlet pipe is connected to a gear pump through a water pipe, one side of the gear pump is connected to a flow valve through a water pipe, and one end of the flow valve is connected to an integrated boiler through a water pipe.

[0006] Furthermore, a pressure sensor is provided between the gear pump and the flow valve.

[0007] Furthermore, a heating rod is provided in the integrated boiler.

[0008] Furthermore, a double-headed grate is provided below the integrated boiler.

[0009] Furthermore, the boiler without a heat exchanger is made of stainless steel or copper.

[0010] The advantages of the utility model are: a series of efficient water control components are adopted, such as solenoid valves, distributors, one-way valves, water pumps, gear pumps and flow valves, etc. These components cooperate with each other to achieve precise control of water flow, ensuring the stability and consistency of water flow during coffee making; by arranging a pressure sensor between the gear pump and the flow valve, the coffee machine can monitor the pressure changes of the system in real time, and adjust the water flow accordingly through the flow valve to ensure that the ideal water pressure can be obtained under different production requirements, thereby making coffee with a strong taste; a heating rod is arranged in the integrated boiler, which can quickly heat up and maintain a constant temperature, providing hot water and steam required for coffee making, making the heating efficiency of the coffee machine higher and shortening the production time; the boiler without a heat exchanger is made of stainless steel or copper, has good corrosion resistance and high temperature resistance, and can ensure the long-term stable operation and safe use of the coffee machine.

[0014] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0016] See also Figure 1-2 As shown, a pressure-adjustable multi-boiler coffee machine comprises a boiler without a heat exchanger 1, an L-shaped joint 2 is arranged on one side of the boiler without a heat exchanger 1, one end of the L-shaped joint 2 is connected to a solenoid valve 3 through a water pipe, one end of the solenoid valve 3 is connected to a single-head distributor 4 through a water pipe, one end of the single-head distributor 4 is arranged with a one-way valve 5, one end of the one-way valve 5 is connected to a water pump 6 through a water pipe, one end of the water pump 6 is connected to a water inlet pipe 7 through a water pipe, one side of the water inlet pipe 7 is connected to a gear pump 8 through a water pipe, one side of the gear pump 8 is connected to a flow valve 9 through a water pipe, and one end of the flow valve 9 is connected to an integrated boiler 10 through a water pipe.

[0017] Among them, a pressure sensor 11 is arranged between the gear pump 8 and the flow valve 9, and the coffee machine can monitor the pressure change of the system in real time, and adjust the water flow rate accordingly through the flow valve 9 to ensure that the ideal water pressure can be obtained under different production requirements, so as to produce coffee with a strong taste;

[0018] The integrated boiler 10 is provided with a heating rod 12, which can quickly heat up and maintain a constant temperature, providing hot water and steam required for coffee making, so that the heating efficiency of the coffee machine is higher and the making time is shortened;

[0019] A double-headed grate 13 is provided below the integrated boiler 10 to prevent coffee grounds or other impurities from accumulating at the bottom of the boiler, thereby reducing the difficulty of cleaning. This helps to maintain the hygiene and operating efficiency of the coffee machine.

[0020] The boiler without heat exchanger 1 is made of stainless steel or copper, which has good corrosion resistance and high temperature resistance, and can ensure the long-term stable operation and safe use of the coffee machine.

[0021] Working principle: hot water flows from the side of the boiler without heat exchanger 1 through the L-shaped joint 2 and the water pipe into the solenoid valve 3, then flows into the single-head distributor 4 through the solenoid valve 3, and flows into the water pump 6 through the one-way valve 5. The hot water is pumped to the water inlet pipe 7 by the water pump 6, and after being pressurized by the gear pump 8, it flows into the flow valve 9 through the pressure sensor 11. The flow rate is controlled by the flow valve 9 to ensure that the ideal water pressure can be obtained under different production requirements, and finally flows out after passing through the integrated boiler 10.
