[0002] Pour-over coffee is a method of extracting coffee by manually controlling the flow rate and direction of hot water to evenly penetrate the coffee grounds, filtering it through filter paper or a dripper. Its core lies in achieving a balance of flavor compounds (such as sweetness, acidity, aroma, and body) by controlling the contact time between water and coffee grounds, the uniformity of extraction, and the selective release of dissolved substances. Because it relies on manual operation and parameter adjustment, pour-over coffee technique mainly depends on the accumulation of human experience. In particular, it is necessary to maintain a stable water flow and a uniform circular trajectory when pouring water. Beginners often cause the coffee grounds to be perforated and the extraction to be uneven due to a chaotic rhythm. Utility Model Content

[0019] Below, in conjunction with Figures 1 to 4 The present invention will be further described in the preferred embodiments and other embodiments. It should be noted that, without conflict, the technical features described below can be arbitrarily combined to form new embodiments.
[0020] refer to Figures 1-4In a preferred embodiment, the present invention provides a pour-over coffee device, including an extraction container assembly 4 and a pour-over coffee guide device. The pour-over coffee guide device includes a control module 8, a gravity detection device 1, and a point light source device 10. The gravity detection device is equipped with a weighing plate 11. The extraction container assembly 4 includes a coffee pot 41 and a filter cup 42. The coffee pot 41 is placed on the weighing plate 11, and the filter cup 42 is placed on the spout of the coffee pot 41. The point light source device 10 includes an emitting element 2 and a mechanical moving device 3. The emitting element 2 is equipped with a control module 8, a gravity detection device 1, and a point light source device 10. In the mechanical moving device 3, the emitting element 2 is provided with a laser projection port 21. The laser projection port 21 is located above the weighing plate 11 and is positioned towards the weighing plate 11. The light spot 9 emitted by the laser projection port 21 is projected into the cup mouth 421. The gravity detection device 1, the mechanical moving device 3, and the emitting element 2 are all electrically connected to the control module 8. The mechanical moving device 3 can control the emitting element 2 to move in the horizontal plane according to a predetermined trajectory, so that the light spot emitted by the laser projection port 21 can move according to the predetermined brewing trajectory. By setting the mechanical moving device 3, the laser reflecting element 2 can be controlled to move in the horizontal plane along a predetermined trajectory, and the light spot 9 emitted by the laser projection port 21 is projected into the cup opening 421, so that the light spot 9 emitted by the laser projection port 21 is located on the surface of the coffee powder in the cup opening 421. The light spot 9 moves on the surface of the coffee powder with the mechanical moving device 3. When the user pours water into the filter cup from the cup opening 421 with a kettle, the user can adjust the spout to follow the movement of the light spot 9 while pouring water, so as to guide the user to pour water along a specific brewing trajectory. The gravity detection device 1 can detect the amount of water poured in real time to ensure that the user can pour a predetermined amount of water along the brewing trajectory within a specific time, thereby maintaining a stable and uniform water flow and a circular trajectory during the coffee powder extraction process, so as to ensure that the coffee powder is effectively extracted. For example, if 90ml of water is poured according to a preset brewing trajectory within 30 seconds, and the time required for the light spot 9 to complete the brewing trajectory is 30 seconds, during the user's water pouring process, if the control module 8 detects, based on the weight information fed back by the gravity detection device 1, that the remaining water volume and the current speed of the light spot 9 are insufficient to complete the remaining preset brewing trajectory, it indicates that the user's water pouring speed per unit time is too fast. The control module 8, by default, increases the speed of the light spot 9 while keeping the water output from the spout constant, to increase the spout's movement speed and ensure that the user pours 90ml of water according to the specific preset brewing trajectory within 30 seconds. Alternatively, if the control module 8 detects, based on the weight information fed back by the gravity detection device 1, that there is still water remaining after completing the remaining preset brewing trajectory according to the current speed of the light spot 9, it indicates that the user's water pouring speed per unit time is too slow. The control module 8, by default, decreases the speed of the light spot 9 while keeping the water output from the spout constant, to ensure that the user pours 90ml of water according to the specific preset brewing trajectory within 30 seconds.In this embodiment, the point light source device 10 is a laser emitting device.
[0021] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the point light source device 10 can rotate up and down around a horizontally oriented rotation axis A to adjust the position of the light spot 9, ensuring that the movement range of the light spot 9 is within the cup opening 421. Specifically, a support column 51 is provided on one side of the scale plate 11, and a fixing member 52 is provided on the support column 51. The point light source device 10 is hinged to the fixing member 52.
[0022] In a preferred embodiment, the fixing member 52 can slide up and down along the support column 51 to match the extraction container assembly 4 of different heights. In this embodiment, the fixing member 52 can be provided with a limiting pin. When the fixing member 52 moves to a suitable position, the limiting pin is engaged with the support column 51 so that the fixing member 52 and the support column 51 remain relatively fixed.
[0023] like Figure 1 and Figure 2 As shown, in a preferred embodiment, a display screen 6 and a camera 7 are also included. Both the display screen 6 and the camera 7 are electrically connected to the control module 8. The monitoring direction of the camera 7 is towards the scale plate 11. The camera 7 can monitor the rim of the cup in real time and transmit the image extracted by the user in real time to the display screen 6 for the user's convenience. In other embodiments, the display screen 6 can be located in a mobile communication device. Specifically, the control module 8 is provided with a wireless communication module 81, and the display screen 6 is connected to the control module 8 via the wireless communication module 81. In one embodiment, the camera 7 and the mobile phone are set separately and independently. The camera 7 is connected to the mobile phone via the wireless communication module 81, such as WiFi or Bluetooth, to realize data transmission, thereby transmitting the image extracted by the user in real time to the mobile phone's display screen. In another embodiment, the camera 7 can also be a camera built into the mobile phone.
[0024] like Figure 1As shown, in a preferred embodiment, the display also includes one or more combinations of a water volume display 61, a water filling time display 62, or a water filling speed display 63. The water volume display 61, the water filling time display 62, or the water filling speed display 63 are distributed at the inner corners of the display screen 6. The water volume display 61 is used to display the amount of water that has been added in real time. The water filling time display 62 is used to display the time taken to add water. The water filling speed display 63 is used to display the current water filling speed of the user. The user can observe the current water volume, water filling time, and water filling speed in real time. By positioning the water level display 61, the water pouring time display 62, and the water pouring speed display 63 at the inner corners of the display surface 111 of the display screen 6, users can easily observe these displays. Furthermore, users can choose to turn the water level display 61, water pouring time display 62, and water pouring speed display 63 on or off during use. In other embodiments, the pour-over coffee guide station may only have one or any combination of two of the water level display 61, water pouring time display 62, and water pouring speed display 63.
[0025] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the camera 7 can monitor the cup opening 421 in real time and feed back the user's real-time extraction record to the control module. The control module compares the user's real-time extraction record with the preset extraction parameters of the pour-over coffee guide device and scores the user's extraction.
[0026] like Figure 3 and Figure 4 As shown, in a preferred embodiment, the mechanical moving device 3 includes a first sliding rod 31 arranged along the X direction and a second sliding rod 32 arranged along the Y direction. The emitting element 2 is disposed on the first sliding rod 31 and can slide along the first sliding rod 31.

[0027] like Figure 3 and Figure 4As shown, in a preferred embodiment, the point light source device 10 further includes a fixed base 33, which is disposed on the first sliding rod 31 and can slide along the first sliding rod 31. The mechanical moving device 3 further includes a first drive motor 34 and a second drive motor 35. The emitting element 2 and the first drive motor 34 are both disposed on the fixed base 33. The output shaft of the first drive motor 34 is provided with a drive gear 36. The first sliding rod 31 is provided with a gear rack 311. The drive gear 36 meshes with the gear rack 311. There are two second sliding rods 32, which are arranged side by side along the X direction. The output shaft of the second drive motor 35 is fixedly connected to one of the second sliding rods 32. The second sliding rod 32 fixedly connected to the second drive motor 35 is a lead screw and is threadedly engaged with one end of the first sliding rod 31. The other second sliding rod 32 is slidably engaged with the other end of the first sliding rod 31. The control module 8 controls the first drive motor 34 and the second drive motor 35 to work according to a preset trajectory so that the emitting element moves along the X and Y directions.
[0028] like Figure 1-3 As shown, in this example, a base 53 is also included. The gravity detection device 1 and the control module 8 are both located on the base 53, and the support column 51 is located on one side of the base 53.
[0029] The beneficial effects of this utility model's pour-over coffee guiding device and pour-over coffee equipment are as follows: By setting the mechanical moving device, the laser reflecting element can be controlled to move along a predetermined trajectory in the horizontal plane, and the laser projection port is located above the scale plate and facing the scale plate, so that the light spot emitted by the laser projection port is projected into the cup mouth of the extraction container assembly. That is to say, when using the pour-over coffee equipment of this utility model, the light spot emitted by the laser projection port is located on the surface of the coffee powder inside the cup mouth. The light spot moves on the surface of the coffee powder with the mechanical moving device. When the user pours water from the extraction container assembly from the cup mouth with a kettle, the user adjusts the kettle spout to follow the movement of the light spot while pouring water, so as to guide the user to pour water along a specific brewing trajectory. The gravity detection device detects the amount of water poured in real time to ensure that the user can pour a predetermined amount of water along the brewing trajectory within a specific time, thereby maintaining a stable and uniform water flow and a circular trajectory during the coffee powder extraction process, so as to ensure that the coffee powder is effectively extracted.
