[0033] Although the numerical ranges and parameters listed in the broad scope of this application are approximate, the numerical values ​​listed in the specific examples are recorded as accurately as possible. However, any numerical value inherently has a certain error. This error is the inevitable result of the standard deviation obtained in its corresponding measurement method.

[0034] In addition, it should be understood that any numerical range described herein is intended to include all subranges subsumed therein. For example, a range of "1 to 10" is intended to include all subranges between (and including) the stated minimum value of 1 and the stated maximum value of 10, i.e., having a minimum value equal to or greater than 1 and a maximum value equal to or less than 10.

[0035] like Figures 1 to 7 As shown, the present application provides a coffee machine, including a main body 100, a bean grinding assembly 200, a water outlet assembly 300, a weighing assembly 500, a filter cup 400, a cup body 700 and a control assembly.

[0036] The bean grinding assembly 200 is disposed on the main body 100 and is used to grind coffee beans into coffee powder. The grinding part of the bean grinding assembly 200 can be adjusted by a person skilled in the art according to actual conditions and is not specifically limited. Specifically, the bean grinding assembly 200 is integrated with a bean storage bin, which is used to store coffee beans. When the bean grinding assembly 200 starts grinding beans, the coffee beans in the bean storage bin enter the bean grinding assembly 200, which facilitates the development of the bean grinding process.

[0037] The filter cup 400, the cup body 700, the water outlet assembly 300 and the weighing assembly 500 are arranged on the same side of the main body 100, the filter cup 400 and the cup body 700 are arranged above the weighing assembly 500, and the water outlet assembly 300 is arranged above the filter cup 400. That is, the filter cup 400, the cup body 700, the water outlet assembly 300 and the weighing assembly 500 are located on the same straight line as a whole. The filter cup 400 is used to receive the coffee powder ground by the bean grinding assembly 200, and the water outlet assembly 300 is used to filter the coffee powder after brewing, so that the brewed coffee liquid enters the cup body 700. The weighing assembly 500 directly weighs the filter cup 400, the cup body 700 and the contents therein, and the water outlet assembly 300 directly sprays the brewing water into the filter cup 400. These components are located on the same side so that the overall process of the coffee machine simulating hand-brewed coffee does not need to be adjusted in position, that is, no manual adjustment is required in the middle.

[0038] like Figure 2 and Figure 5 As shown, the bean grinding assembly 200 is provided with a powder outlet channel 210 , and the powder outlet channel 210 extends to above the filter cup 400 , and the coffee powder ground by the bean grinding assembly 200 falls into the filter cup 400 along the powder outlet channel 210 .

[0039] The control component is electrically connected to the bean grinding component 200, the weighing component 500, and the water outlet component 300, and the control component controls the water output of the water outlet component 300 according to the weight data of the weighing component 500. Specifically, the control component can be operated in the form of a touch panel or a touch button for information input, and those skilled in the art can select according to actual needs, without specific limitation.

[0040] In actual operation, the user selects the required type of coffee through the control component. The control component controls the bean grinding component 200 to grind out the required weight of coffee powder, and transports the coffee powder to the filter cup 400 through the powder outlet channel 210. The weighing component 500 feeds back the weight change of the filter cup 400 to the control component in real time. The control component controls the bean grinding component 200 to stop running when the weight change of the filter cup 400 reaches the set value. After the bean grinding component 200 stops, the control component starts the water outlet component 300 to inject water into the coffee powder in the filter cup 400 for brewing. While the water outlet component 300 is injecting water for brewing, the weighing component 500 continues to record the weight change of the filter cup 400. After the weight change reaches the set value, the control component controls the water outlet component 300 to stop discharging water to ensure the water-powder ratio of brewing. After the coffee liquid in the filter cup 400 is filtered, it falls into the cup body 700 to obtain the required coffee.

[0041] Preferably, the bean storage bin is located at the top of the main body 100, which is convenient for the user to add coffee beans and enables the user to intuitively observe the remaining coffee beans in the bean storage bin.

[0042] In one embodiment, a filter screen is provided at the bottom of the filter cup 400, and the filter screen is used to receive coffee powder and allow the brewed coffee liquid to pass through the filter screen and fall into the cup body 700. Furthermore, the filter screen is fixed to the bottom of the filter cup 400 in a buckle form, which is convenient for users to clean.

[0043] Preferably, Figure 7 As shown, the water outlet assembly 300 includes a rotating water outlet, which starts to discharge water from the middle of the water outlet assembly 300 and gradually moves to the edge of the water outlet assembly 300. That is, the water outlet assembly 300 as a whole adopts a spiral water outlet brewing structure, so that the water outlet trajectory is to move from the middle of the filter cup 400 to the edge in a spiral. Those skilled in the art can select a suitable rotating water outlet brewing device and adjust it as needed, without specific limitation. The rotating water outlet enables the water outlet assembly 300 to simulate the hand-brewed brewing method for brewing, and finally obtain coffee liquid with good flavor.

[0044] Specifically, the brewing structure of the water outlet assembly 300 may use the solution of CN218304535U.

[0045] Preferably, Figures 5-6 As shown, a powder outlet hole is provided at the center of the water outlet assembly 300, and the powder outlet channel 210 extends through the powder outlet hole to the top of the filter cup 400. The extension of the powder outlet channel 210 through the powder outlet hole can make the overall integration of the coffee machine higher, which is conducive to reducing the overall size of the coffee machine. Specifically, after the powder outlet hole is provided in the water outlet assembly 300, those skilled in the art can adjust the structure of the water outlet assembly 300 as needed to ensure the realization of the water outlet trajectory.

[0046] In one embodiment, if Figures 4 to 6 As shown, the powder outlet channel 210 is in the same straight line as the center of the filter cup 400, so that the coffee powder falls vertically into the middle of the filter cup 400. The powder outlet channel 210 is arranged vertically to ensure that the coffee powder slides outward from the center of the filter cup 400 when falling into the filter cup 400, ensuring that the distribution of the coffee powder in the filter cup 400 meets expectations, thereby ensuring the brewing effect.

[0047] Preferably, Figures 1 to 3 As shown, the powder outlet channel 210 includes a fixed section 211 and a telescopic section 212. One end of the fixed section 211 is fixedly connected to the bean grinding assembly 200, and the other end of the fixed section 211 is connected to the telescopic section 212 by sliding through a telescopic drive structure 213. The telescopic section 212 slides along the fixed section 211 under the action of the telescopic drive structure 213.

[0048] Furthermore, a dust baffle is provided at the main body 100 corresponding to the powder outlet channel 210, and a torsion spring is provided between the dust baffle and the main body 100. When the telescopic section 212 of the powder outlet channel 210 slides out, the torsion spring that pushes the dust baffle open reaches above the filter cup 400, and when the telescopic section 212 of the powder outlet channel 210 slides back, the torsion spring resets the dust baffle to block the powder outlet channel 210, preventing dust from entering the powder outlet channel 210 and ensuring cleanliness.

[0049] Preferably, Figures 2-3 As shown, the telescopic driving structure 213 includes a connecting rod bracket 213a, a telescopic connecting rod 213c and a driving motor 213b; the driving motor 213b is fixed to the end of the fixed section 211 away from the grinding assembly 200 through the connecting rod bracket 213a, the output end of the driving motor 213b is fixedly connected to one end of the telescopic connecting rod 213c, and the other end of the telescopic connecting rod 213c is sleeved on the transmission column 212a on the surface of the telescopic section 212; the telescopic connecting rod 213c reciprocates under the drive of the driving motor 213b, thereby driving the telescopic section 212 to reciprocate and retract.

[0050] Preferably, a filter cup 400 bracket is further included, and the filter cup 400 bracket is connected to the main body 100 for supporting the filter cup 400 .

[0051] Furthermore, a vibration motor is provided on the filter cup 400 support, and the filter cup 400 is vibrated before brewing, so that the coffee powder in the filter cup 400 is vibrated to a flat surface, thereby ensuring the brewing effect.

[0052] In one embodiment, if Figure 2 and Figure 5 As shown, the main body 100 further includes a water tank 600, which pumps water to the water outlet assembly 300 through a water pump. The water tank 600 is provided so that there is no need to manually add water during brewing, and the entire water path is integrated into the main body 100, reducing the occurrence of water path pollution problems. Specifically, the water tank 600 is directly connected to an external water supply device or pipeline.

[0053] Furthermore, a heating module and a filtering module are provided in the water storage tank 600 to ensure the temperature and water quality of the brewing water.

[0054] In one embodiment, if Figure 6 As shown, a water storage pan 510 is provided above the weighing assembly 500. Specifically, the water storage pan 510 is used to receive the dripping or discarded liquid from the cup body 700 and the filter cup 400. Furthermore, a drain port is provided in the water storage pan 510, and the drain port is connected to an external sewage pipe. The drain port is used to discharge the liquid in the water storage pan 510 that exceeds a set height to ensure the accuracy of the weighing assembly 500.

[0055] Specifically, when the coffee machine provided by the present application is actually used, the following steps can be used for brewing:

[0056] Select the desired type of coffee through the control component;

[0057] The control component controls the bean grinding component 200 to grind coffee powder of a required weight, and delivers the coffee powder to the filter cup 400 through the powder outlet channel 210. The weighing component 500 feeds back the weight change of the filter cup 400 to the control component in real time.

[0058] The control component controls the bean grinding component 200 to stop running when the weight change of the filter cup 400 reaches a set value;

[0059] After the bean grinding assembly 200 stops, the control assembly starts the water outlet assembly 300 to inject water into the coffee powder in the filter cup 400 for brewing;

[0060] While the water outlet component 300 is injecting water for brewing, the weighing component 500 continues to record the weight change of the filter cup 400. When the weight change reaches the set value, the control component controls the water outlet component 300 to stop discharging water. After the coffee liquid in the filter cup 400 is filtered, it falls into the cup body 700 to obtain the desired coffee.

[0061] Furthermore, when the weighing component 500 detects that the weight of the filter cup 400 stops changing, it feeds back to the control component, and the control component detects whether the bean grinding component 200 or the water outlet component 300 is in a working state. If the bean grinding component 200 or the water outlet component 300 is still in a working state, the control component controls the bean grinding component 200 or the water outlet component 300 to stop working and issues an error prompt.

[0062] In addition, those skilled in the art should understand that, although there are many problems in the prior art, each embodiment or technical solution of the present application can be improved in only one or several aspects, without having to solve all the technical problems listed in the prior art or background technology at the same time.
