AI Technical Summary
Existing pour-over coffee machines cannot achieve a spiral water pouring path that gradually increases in size, resulting in uneven penetration of hot water into the coffee grounds, a large extraction error in the coffee liquid, and an inability to consistently produce coffee liquid with a consistent taste.
The system adopts a structural design that includes a base, turntable, rotating shaft, water inlet head, heater, control board, first motor and second motor. The control board works in conjunction with the first motor to drive the turntable to rotate, and the second motor drives the rotating shaft to rotate within a specific angle range. This causes the direction of the water inlet head to change from vertically downward at a constant speed to tilted downward, achieving a spiral water inlet with the path increasing from small to large, simulating the operation of hand-drip coffee.
Ensure that hot water evenly soaks the coffee grounds, reducing extraction errors and consistently producing coffee with a uniform taste.

[0024] In this paper, the "embodiment" means that the specific features, structures or characteristics described in conjunction with the embodiment can be included in at least one embodiment of the present application. The phrase appears at various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment independent of or alternative to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0026] like Figures 1-3 As shown, a pour-over coffee machine includes a base 1, a turntable 12, a rotating shaft 43, a water inlet head 22, a heater 2, a control board 3, a first motor 41, and a second motor 42. The lower end of the base 1 has a placement position 11. The turntable 12 is rotatably connected to the placement position 11. The rotating shaft 43 is located directly above the turntable 12 and parallel to it. One end of the rotating shaft 43 is rotatably connected to a side wall of the base 1. The water inlet head 22 is vertically fixed to the other end of the rotating shaft 43. The heater 2 is mounted on the base 1 and has a heating channel (not shown in the attached diagram). The outlet of the heating channel is connected to the inlet of the water inlet head 22 via a hose 21. The inlet of the heating channel is connected to a water source. The heater 2 heats the water flowing through the heating channel. The control board 3, the first motor 41, and the second motor 42 are all mounted on the base 1. The control board 3 controls the heating of the heater 2, the rotation of the turntable 12 by the first motor 41, and the second motor 42. The machine 42 drives the rotating shaft 43 to rotate within a specific angle range. The water inlet of the heating channel is connected to the tap water pipe. When in use, first place the coffee cup containing filter paper and coffee powder on the turntable 12, then open the tap water valve. Clean water will flow into the heating channel, be heated into hot water, and then spray out through the hose 21 from the water inlet head 22. At the same time, under the control of the control board 3, the first motor 41 will drive the coffee cup to rotate, and the second motor 42 will drive the rotating shaft 43 to rotate within a specific angle range, so that the orientation of the water inlet head 22 changes from vertically downward at a constant speed to tilted downward. This causes the dripping position of the hot water on the coffee powder to gradually shift outward from the center of the coffee powder along the radial direction of the coffee cup. Finally, combined with the rotation of the coffee cup, a spiral water inlet with the path from small to large is achieved, which better simulates the operation of hand-drip coffee, ensures that the hot water evenly penetrates the coffee powder, reduces the extraction error of the coffee liquid, and makes coffee with a better consistent taste.
[0027] Specifically, when the water inlet head 22 swings, the hose 21 will undergo adaptive deformation; the base 1 consists of a base and a mounting plate vertically mounted on the base; the heater 2 consists of a hollow shell and a heat exchange tube and a heating tube built into the shell. A heating channel is formed inside the heat exchange tube. When in use, the heating tube will heat the heat exchange tube and heat the clean water flowing through the heating channel into hot water. The heater 2 can be purchased through market channels and will not be described in this embodiment.
[0028] In one embodiment, the second motor 42 may be a servo motor to drive the rotating shaft 43 to rotate at a constant speed within a specific angular range.
[0029] Further, a water temperature sensor 51 is arranged at the water outlet end of the heating channel, and a temperature control switch 52 is integrated on the heater 2 and electrically connected with the water temperature sensor 51. The water temperature sensor 51 can instantly detect the temperature of the hot water flowing out of the water outlet end of the heating channel and feed back the temperature information to the control board 3. For example, when the temperature of the hot water reaches 90 degrees, the control board 3 will disconnect the temperature control switch 52 to stop the heater 2 from heating. When the temperature of the hot water is lower than 90 degrees, the control board 3 will connect the temperature control switch 52 to make the heater 2 heat up, so as to control the temperature of the hot water at about 90 degrees to extract coffee liquid at a proper water temperature.
[0030] Further, a limit switch 13 is arranged on the upper end of the side wall of the base 1 and adjacent to the water injection head 22, and the limit switch 13 is electrically connected with the control board 3. When the water injection head 22 is rotated to the maximum inclination angle by the rotating shaft 43, the second motor 42 will drive the rotating shaft 43 to rotate back to the original position, so as to extract coffee liquid by the spiral water injection mode or help the water injection head 22 to return to the original position. When the water injection head 22 is swung to be vertically downward, the side wall of the water injection head 22 will trigger the limit switch 13, and the limit switch 13 will feed back an electric signal to the control board 3. The control board 3 will shut down the second motor 42 to keep the water injection head 22 in the original vertical position.
[0031] Further, the limit switch 13 is a micro switch, which is sensitive to triggering and can effectively improve the returning accuracy of the water injection head 22.
[0032] Further, the base 1 is provided with a control screen 6, which is electrically connected with the control board 3. The user can operate the control board 3 by touching the control screen 6 to control the start and stop of the first motor 41, the second motor 42, the heater 2, the water temperature sensor 51, the temperature control switch 52 and the limit switch 13, or set the preset values of the corresponding components, such as the rotating speed of the first motor 41 and the second motor 42, the measuring temperature of the water temperature sensor 51, etc.
[0033] Further, the base 1 is also provided with a water tank 7 and a water pump 81. The bottom end of the water tank 7 is communicated with the water inlet end of the heating channel through the water pump 81. The water tank 7 can be used to store clean water for brewing coffee. During use, the water pump 81 will pump the clean water in the water tank 7 to the heating channel through the water pipe, so that the clean water is heated into hot water in the heating channel and then sprayed out of the water injection head 22 through the hose 21.
[0034] Further, the inner cavity of the water tank 7 is open to the upper side, and the top of the water tank 7 is detachably provided with a tank cover 9. The tank cover 9 covers the opening of the inner cavity of the water tank 7, and the detachable tank cover 9 is convenient for the user to supplement clean water into the inner cavity of the water tank 7 or clean the inner cavity of the water tank 7.
[0035] Further, the water outlet of the water pump 81 is provided with a flow valve 82, which monitors the water flow in real time when the water pump 81 pumps clean water into the heating channel each time the water pump 81 is started, and when the water flow reaches a preset value, the control mainboard 3 controls the flow valve 82 to close, so as to prevent the water pump 81 from continuously pumping water into the heating channel, so as to control the injection amount of hot water each time the coffee is made.
[0036] Further, the first motor 41 is vertically upwardly arranged at the lower end of the base 1, and the output shaft of the first motor 41 extends to the placing position 11, and the rotating disc 12 is coaxially fixed on the extending end of the output shaft of the first motor 41, and the second motor 42 is horizontally arranged at the upper end of the base 1, and the output shaft of the second motor 42 extends above the rotating disc 12, and the output shaft of the second motor 42 constitutes the rotating shaft 43, so that the first motor 41 directly drives the rotating disc 12 to rotate, and the second motor 42 directly drives the water injection head 22 to swing, reduces the transmission assembly, and makes the structure of the hand coffee maker more simple and convenient to maintain.
[0037] Further, the second motor 42 is a stepping motor, so as to drive the rotating shaft 43 to rotate at a low speed within a specific angle range.
[0038] Obviously, the above-described embodiments are only some embodiments of the present application, not all embodiments, and the preferred embodiments of the present application are given in the drawings, but do not limit the patent scope of the present application. The present application can be realized in many different forms, and conversely, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or equivalently replace some technical features therein.
