Description

Technical Field

[0001] The utility model relates to a coffee machine, in particular to an imitation hand-brewed coffee machine. Background Art

[0002] There are two common ways of brewing coffee, one is Italian brewing and the other is manual brewing. The working process of Italian brewing is to weigh a certain amount of coffee beans, then put the coffee beans into a grinder and grind them into coffee powder, then put the ground coffee powder into a special coffee brewing machine and pour high-temperature and high-pressure water into the coffee powder to obtain coffee liquid (concentrate). The process of manual brewing is to weigh a certain amount of coffee beans, then put the coffee beans into a grinder and grind them into coffee powder, then put them into a special filter paper, and manually add hot water to flush out the coffee liquid. The difference between the above two brewing methods is that the hot water is added in different ways at the end. The Italian method is to pressurize the hot water into the coffee, while the hand-brewed method is to add the hot water manually. The coffee flavors brewed in the two ways are different. At present, the existing automatic coffee machines on the market are all Italian brewing, and there is no equipment imitating manual brewing. Manual brewing depends on personal brewing technology. Different people will form different tastes in the links of weighing beans, grinding beans, and adding water, and cannot form a unified and standard manual brewing taste, and the efficiency is also low. Therefore, developing an imitation hand-brew coffee machine has become a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0035] The working principle of the utility model is as follows: before starting the coffee machine, filter paper is placed in the filter holder 505, and a cup is placed in the water cup placement area. After selecting coffee beans, the left and right translation drive motor 306 is started to drive the hopper and other parts to move to the corresponding bean bin 201 and stop. The front and rear telescopic drive motor 313 is started to drive the hopper to retreat. During the retreat process, the paddle 311 contacts the arm 208 of the bean bin 201 to push open the bean outlet valve 207. Then the screw drive motor 205 is started to drive the bean outlet screw 203 to rotate, push out the coffee beans in the bean bin 201, and drop them into the weighing hopper 316 below. When the weighing hopper 316 reaches the set weight, the motor stops, the bean weighing assembly 3 moves away, and during the forward movement, the paddle 311 leaves the arm 208 of the bean bin 201 to close the bean outlet valve 207, and the work of the bean bin 201 ends (when the photoelectric switch 209 is used to detect the remaining coffee beans in the bean bin 201, a light prompt or sound prompt is issued when it is less than a certain amount). Next, the left and right translation drive motor 306 starts, moves the weighing hopper 316 to the top of the bean grinding assembly 4 and then stops, then the unloading valve servo 317 opens the valve baffle under the hopper to let the coffee beans fall into the bean grinding assembly 4 (the unloading valve servo 317 can rotate to a fixed angle according to the signal, and its function is to control the opening and closing of the baffle under the hopper to prevent the beans from falling to other places when the hopper receives the coffee beans), then the bean weighing assembly 3 returns, and the work of the bean weighing assembly 3 is completed. At this time, the rotating servo 502 of the filter assembly 5 starts to move the filter bracket 505 to the bottom of the bean grinding assembly 4, and then the transmission motor 405 of the bean grinding assembly 4 starts, and drives the grinding core 407 to rotate through the synchronous pulley 403 and the synchronous belt 404, and the rotating grinding core 407 cooperates with the grinding disc 406 to grind the coffee beans into powder and drop it into the filter paper in the filter paper bracket, and the work of the bean grinding assembly 4 is completed. At this time, the rotary servo 502 of the filter assembly 5 is started again, and the filter bracket 505 filled with coffee powder is moved to the bottom of the flushing assembly 8. Then, the flushing assembly 8 starts to work, and the left servo 802 and the right servo 803 rotate left and right according to a preset program, driving the water outlet 808 to move. At the same time, the water outlet 808 starts to discharge hot water. When the preset water volume is reached, the work of the flushing assembly 8 is completed.
