[0043] The present invention provides a coffee machine 100, such as Figures 1 to 8 As shown, the coffee machine 100 includes a body 1 and a motion component 2, a bean grinding device 3, a powder outlet block 4 and a piercing component 5 arranged on the body 1; the body 1 has a capsule cavity 11; the bean grinding device 3 has a powder outlet channel 31 connected to the capsule cavity 11. It can be understood that the capsule cavity 11 of the body 1 is used to place capsule coffee 200 and can provide a place for brewing coffee. Hot water is passed into the capsule cavity 11 to extract coffee to form coffee liquid. The bean grinding device 3 is used to grind coffee beans to form coffee powder, and the coffee powder enters the capsule cavity 11 through the powder outlet channel 31. At this time, the ground coffee powder can be extracted by hot water in the capsule cavity 11, so as to form an integrated structure of grinding beans, brewing coffee powder and brewing capsule coffee 200. In addition, it should be noted that the main body 1 is also provided with other conventional components for brewing coffee, such as a heating system 9, a water tank 10, a control system 20 and other components, wherein the heating system 9 is used to heat the room temperature water in the water tank 10 to a certain temperature so as to pass the water into the capsule cavity 11 for extracting the capsule coffee 200 or coffee powder to be brewed.

[0044] like Figure 1 , Figures 4 to 6As shown, the motion component 2 includes a driving device 21 and a first moving part 22 and a second moving part 23 connected to the output end of the driving device 21; the driving device 21 drives the piercing component 5 to move back and forth along the first direction through the first moving part 22 to extend into or out of the capsule cavity 11, and the driving device 21 drives the powder outlet blocking part 4 to move along the second direction through the second moving part 23 to block the powder outlet channel 31 or open the powder outlet channel 31; specifically, in this embodiment, the first direction and the second direction are not parallel, which can effectively avoid interference between the piercing component 5 and the powder outlet blocking part 4. It can be understood that when the driving device 21 drives the piercing assembly 5 to move along the first direction through the first moving part 22 until it extends into the capsule cavity 11, the driving device 21 drives the powder outlet blocking member 4 to move along the second direction through the second moving part 23 to block the powder outlet channel 31; when the driving device 21 drives the piercing assembly 5 to move in the opposite direction along the first direction through the first moving part 22 until it extends out of the capsule cavity 11, the driving device 21 drives the powder outlet blocking member 4 to move in the opposite direction along the second direction through the second moving part 23 to open the powder outlet channel 31.

[0045] Specifically, when capsule coffee 200 is placed in the capsule cavity 11, the driving device 21 is started, and the driving device 21 drives the piercing component 5 to move along the first direction through the first moving part 22 to extend into the capsule cavity 11. At the same time, the driving device 21 drives the powder outlet blocking part 4 to move along the second direction through the second moving part 23 to block the powder outlet channel 31. At this time, the piercing component 5 can pierce the capsule coffee 200 placed in the capsule cavity 11 to form a piercing position, and hot water is introduced into the capsule coffee 200 through the piercing position to extract the coffee in the capsule coffee 200 to form coffee liquid. When the bean grinding device 3 needs to grind coffee beans and brew, the driving device 21 is started, and the driving device 21 drives the powder outlet blocking member 4 to move along the second direction to block the powder outlet channel 31 through the second moving member 23. At the same time, the driving device 21 drives the piercing assembly 5 to move along the first direction to extend into the capsule cavity 11 through the first moving member 22. At this time, the coffee beans can be placed in the bean grinding device 3 for grinding to form coffee powder. After grinding, the driving device 21 drives the powder outlet blocking member 4 to move in the second direction in the opposite direction through the second moving member 23 to open the powder outlet channel 31. At the same time, the driving device 21 drives the piercing assembly 5 to move in the first direction to extend out of the capsule cavity 11 through the first moving member 22. At this time, the ground coffee powder enters the capsule cavity 11 through the powder outlet channel 31, and hot water is introduced to extract the coffee in the coffee powder to form coffee liquid.

[0046] In summary, the bean grinding device 3 of the coffee machine 100 is connected to the capsule cavity 11 of the body 1 through the powder outlet channel 31, and is respectively connected to the first moving part 22 and the second moving part 23 through the output end of the driving device 21. Therefore, the driving device 21 can cooperate with the first moving part 22 and the second moving part 23 to make the piercing component 5 extend into the capsule cavity 11, and at the same time, the powder outlet block 4 blocks the powder outlet channel 31. At this time, the capsule cavity 11 can hold capsule coffee 200 and pierce and brew through the piercing component 5; or the driving device 21 can cooperate with the first moving part 22 and the second moving part 23 to make the piercing component 5 extend out of the capsule cavity 11, and at the same time, the powder outlet block 4 opens the powder outlet channel 31. At this time, the coffee powder ground by the bean grinding device 3 can enter the capsule cavity 11 through the powder outlet channel 31 for brewing. Therefore, the coffee machine 100 can select the operations of grinding beans, brewing coffee powder and brewing capsule coffee 200 according to actual needs, and can integrate the operations of grinding beans, brewing coffee powder and brewing capsule coffee 200 into one, thereby improving the versatility of the coffee machine 100. The capsule coffee 200 is automatically punctured by the puncturing component 5, which can effectively avoid the problem of insufficient capsule puncture and easy bounce after puncture.

[0047] In some embodiments, Figure 1 , Figures 4 to 6 As shown, the driving device 21 includes a rotary driving device, the output end of the rotary driving device is connected to the first moving member 22, the outer wall of the first moving member 22 is provided with a slide groove 221, and the piercing assembly 5 is slidably arranged in the slide groove 221; when the rotary driving device drives the first moving member 22 to rotate, it can drive the piercing assembly 5 to move relative to the slide groove 221 along the first direction. It should be noted that the rotary driving device is specifically a rotary motor, and the first moving member 22 can be sleeved and connected with the output end of the rotary motor. Specifically in this embodiment, the first moving member 22 has a first plug-in slot, and the output end of the rotary motor is plugged into the first plug-in slot of the first moving member 22. It can be understood that when the rotary driving device drives the first moving member 22 to perform a rotary motion, the piercing assembly 5 moves along the slide groove 221 to form a linear motion, so that the rotary motion of the first moving member 22 can be converted into a linear motion, driving the piercing assembly 5 to extend into the capsule cavity 11 to pierce the coffee capsule in the capsule cavity 11, or driving the piercing assembly 5 to extend out of the capsule cavity 11 to leave the capsule cavity 11.

[0048] In some embodiments, Figure 1As shown, the first moving member 22 is provided with an arc guide groove extending along its own circumferential direction and along its own axial direction, and the axial direction of the first moving member 22 is consistent with the first direction, and the arc guide groove is a slide groove 221; specifically in the present embodiment, the first moving member 22 is vertically arranged, that is, the axial direction of the first moving member 22 is consistent with the vertical direction, so as to be able to drive the piercing assembly 5 to move up and down. It can be understood that by setting the arc guide groove, the rotational movement of the first moving member 22 can be adapted, so that the piercing assembly 5 can smoothly reciprocate along the vertical direction along the slide groove 221 under the rotational movement of the first moving member 22, so as to move to extend into or extend out of the capsule cavity 11. In addition, it should be noted that in the present embodiment, the first moving member 22 is a cylindrical structure, which is convenient for forming an arc groove on the outer wall of the first moving member 22. Of course, in other embodiments, the first moving member 22 can also be other suitable shapes, which are not particularly limited here.

[0049] In some embodiments, along the circumferential direction of the first moving member 22, the angle between the first end and the second end of the arc-shaped guide groove around the central axis of the first moving member 22 is 90 degrees. It can be understood that the depth of the puncture assembly 5 extending into the capsule cavity 11 or the height of the puncture assembly 5 extending out of the capsule cavity 11 and staying at a preset position can be controlled by controlling the angle of the first moving member 22 to achieve the automatic puncture function by controlling the movement of the puncture assembly 5 up and down to different positions.

[0050] In some embodiments, Figure 1 , Figures 5 to 8 As shown, the main body 1 also has an opening 12 connected to the capsule cavity 11, and the powder outlet channel 31 is arranged opposite to the opening 12 of the main body 1 and there is a gap; the powder outlet baffle 4 is slidably arranged in the gap; the powder outlet baffle 4 has a through hole 41, and the driving device 21 drives the powder outlet baffle 4 to move along the second direction until the through hole 41 is located in the gap or is staggered with the gap. Specifically, the second direction can be a transverse direction, and the powder outlet baffle 4 moves left and right along the transverse direction until the through hole 41 is located in the gap or is staggered with the gap. It can be understood that when the powder outlet block 4 moves along the second direction so that the through hole 41 of the powder outlet block 4 is located at the gap, the powder outlet channel 31, the through hole 41 and the opening 12 of the body 1 are connected in sequence, and the coffee powder ground by the bean grinding device 3 can enter the capsule cavity 11 after passing through the powder outlet channel 31, the through hole 41 and the opening 12 of the body 1 in sequence, and then the powder outlet block 4 is moved in the opposite direction so that the through hole 41 of the powder outlet block 4 and the gap are staggered with each other. At this time, the powder outlet channel 31 and the opening 12 of the body 1 are blocked by the powder outlet block 4 to form a disconnected state, and the coffee powder brewing operation or the capsule coffee 200 brewing operation can be performed at this time. Therefore, by controlling the moving state of the powder outlet block 4, the powder outlet state and the powder outlet amount can be quickly controlled, which has the characteristics of simple structure and convenient operation.

[0051] In some embodiments, Figure 7 and Figure 8 As shown, the driving device 21 also includes a guide member 24; the output end of the rotating driving device is connected to the second moving member 23; specifically in the present embodiment, the second moving member 23 is provided with a second plug-in slot, the output end of the rotating motor is plugged into the second plug-in slot of the second moving member 23, and the second moving member 23 is plugged into the first plug-in slot of the first moving member 22, so that the output end of the rotating motor, the second moving member 23 and the first moving member 22 are sequentially connected, thereby improving the compactness of the overall structure and enabling the rotating motor to simultaneously drive the first moving member 22 and the second moving member 23 to perform rotational motion. The guide member 24 is arranged on the main body 1, and the guide member 24 is formed with a guide groove 241 consistent with the second direction; the powder outlet blocking member 4 is provided with a connecting hole 42 extending in a direction intersecting the second direction, and the second end of the second moving member 23 is slidably inserted in the connecting hole 42, and the powder outlet blocking member 4 is slidably arranged in the guide groove 241; specifically in the present embodiment, the second end of the second moving member 23 is provided with a pin 231, and the second moving member 23 is slidably inserted in the connecting hole 42 through the pin 231, and the powder outlet blocking member 4 is provided with the connecting hole 42 extending perpendicularly to the second direction.

[0052] It can be understood that the second moving part 23 is driven to rotate by the rotating motor. At this time, the second moving part 23 can slide along the connecting hole 42 of the powder outlet block 4 during the rotation process, thereby driving the powder outlet block 4 to slide along the guide groove 241, wherein the extension direction of the guide groove 241 is consistent with the first direction. Therefore, the powder outlet block 4 is driven by the rotating motor and under the guidance of the connecting hole 42 and the guide groove 241. It can move in a straight line along the guide groove 241 so that it can move to the through hole 41 of the powder outlet block 4, which is located in the gap between the powder outlet channel 31 and the opening 12 or staggered with the gap. Therefore, by opening a slide groove 221 on the outer wall of the first moving part 22, opening a connecting hole 42 on the powder discharge blocking part 4, and arranging a guide part 24 on the main body 1, the rotary drive device can simultaneously drive the first moving part 22 and the second moving part 23 to rotate, so as to drive the piercing assembly 5 to form a linear motion along the slide groove 221 of the first moving part 22, and drive the powder discharge blocking part 4 slidingly connected to the second moving part 23 to move linearly along the guide groove 241, so that the rotary drive force formed by the rotary drive device can form linear motion in two directions, thereby effectively improving the compactness of the structure.

[0053] In some embodiments, Figure 7 and Figure 8As shown, the powder-discharging block 4 is a T-shaped plate, and the connecting hole 42 is opened at the short end of the T-shaped plate and extends along the extension direction of the short end, and the through hole 41 is opened at the long end of the T-shaped plate. It should be noted that the long end of the T-shaped plate refers to the longer end, and the short end is the shorter end. It can be understood that by opening the connecting hole 42 at the short end of the T-shaped plate and the through hole 41 at the long end of the T-shaped plate, the connection hole 42 and the through hole 41 do not interfere with each other, which facilitates the movement of the powder-discharging block 4, and enables the long end of the T-shaped plate to effectively block the powder-discharging channel 31 from being connected to the capsule cavity 11 when not feeding, and has sufficient length to support the T-shaped plate to block the powder-discharging channel 31 from being connected to the capsule cavity 11, thereby improving the compactness of the structure of the powder-discharging block 4.

[0054] In some embodiments, two guide members 24 are provided, and the two guide members 24 correspond to the short end and the long end of the T-shaped plate, respectively. It can be understood that, since the width of the long end of the T-shaped plate is different from the width of the short end, two guide members 24 are provided to correspond to the short end and the long end of the T-shaped plate, respectively, so as to adapt to the shape of the short end and the long end of the T-shaped plate. The two guide members 24 cooperate to guide the whole T-shaped plate, so that the T-shaped plate can move in a straight line until the through hole 41 is located at the gap or staggered with the gap.

[0055] In some embodiments, Figure 2 and Figure 3 As shown, the body 1 is located in the capsule cavity 11 and is also provided with a magnetic member 61 and a magnetic sensor 62; the magnetic member 61 is movably connected to the body 1, and the magnetic member 61 can move relative to the body 1 to the sensing area of ​​the magnetic sensor 62 or outside the sensing area. It can be understood that when the capsule coffee 200 is not placed in the capsule cavity 11, the magnetic member 61 is located outside the sensing area of ​​the magnetic sensor 62; when the capsule coffee 200 is placed in the capsule cavity 11, the capsule coffee 200 can drive the magnetic member 61 to move relative to the body 1 to the sensing area of ​​the magnetic sensor 62, and at this time, an induction signal can be formed and transmitted to the control circuit of the coffee machine 100, so as to identify whether the capsule coffee 200 has entered the capsule cavity 11, effectively avoiding the user from starting the coffee machine 100 when the capsule coffee 200 is omitted, effectively avoiding affecting the life of the coffee machine 100, and affecting the process of brewing coffee.

[0056] In some embodiments, the magnetic member 61 is rotatably connected to the body 1 via a torsion spring 63 and is located in the capsule cavity 11 . The magnetic member 61 rotates to contact the magnetic sensor 62 under the action of an external force, or the magnetic member 61 rotates to separate from the magnetic sensor 62 under the action of the torsion spring 63 . Specifically in this embodiment, the magnetic member 61 and the magnetic sensor 62 are both arranged on the inner wall of the capsule cavity 11, and the magnetic sensor 62 is arranged below the magnetic member 61. The torsion spring 63 extends along the inner wall of the capsule cavity 11 to the bottom wall of the capsule cavity 11, and one end of the torsion spring 63 is connected to the magnetic member 61, and the other end is arranged at the bottom of the capsule cavity 11. When the capsule coffee 200 is placed in the capsule cavity 11, the magnetic member 61 is driven to rotate downward until it contacts the inner wall of the capsule cavity 11. At this time, the magnetic member 61 contacts the magnetic sensor 62 located below the magnetic member 61 to form an induction signal; when the capsule coffee 200 leaves the capsule cavity 11, the magnetic member 61 automatically resets under the action of the torsion spring 63 to separate the magnetic member 61 and the magnetic sensor 62. Therefore, through the cooperation of the magnetic member 61 and the torsion spring 63, the magnetic member 61 can rotate smoothly and reset automatically, and can quickly sense whether the capsule coffee 200 is placed in the capsule cavity 11. By arranging the magnetic member 61 and the magnetic sensor 62 on the inner wall of the capsule cavity 11, the compactness of the structure is improved, and the rotation of the magnetic member 61 can be effectively prevented from interfering with the operation of placing or removing the capsule coffee 200.

[0057] In some embodiments, Figure 1 and Figure 4 As shown, the body 1 is also provided with a circuit board 7, and the circuit board 7 is provided with at least one first sensing element and at least one second sensing element, the first sensing element is electrically connected to the piercing assembly 5, and the second sensing element is electrically connected to the powder outlet block 4; the output end of the rotary drive device is provided with an electrical connector 8, and the rotary drive device drives the electrical connector 8 to move to contact with the first sensing element or the second sensing element to form a closed loop. It can be understood that by driving the electrical connector 8 to contact with the first sensing element or the second sensing element during the rotation of the rotary drive device to form a closed loop, signals at different positions can be sent to the control system 20, thereby controlling the movement of the piercing assembly 5 up and down to different positions to realize the automatic piercing function, and realizing the opening or closing of the powder outlet of the powder outlet block 4 to realize different functions such as grinding coffee beans or brewing coffee. Specifically in this embodiment, the electrical connector 8 is a brass sheet, and the contacts on the brass sheet are driven by the rotary drive device to rotate to different positions of the circuit board 7 to connect to start different functions of the coffee machine 100.

[0058] In some embodiments, Figure 1As shown, the piercing assembly 5 includes a mounting member 51, a slider 52, a pricking needle 53 and a water inlet member 54.

At this time, the driving device 21 drives the powder outlet blocking part 4 to move along the second direction from blocking the powder outlet channel 31 to opening the powder outlet channel 31 through the second moving part 23, and the coffee powder enters the capsule cavity 11.

[0063] It should be noted that the step of brewing capsule coffee 200 and the bean grinding device 3 can be performed sequentially or independently according to a preset operation, and no special limitation is made here.

[0064] In summary, the control method of the coffee machine 100 connects the first moving part 22 and the second moving part 23 respectively through the output end of the driving device 21, so the driving device 21 can make the piercing component 5 extend into the capsule cavity 11 through the cooperation of the first moving part 22 and the second moving part 23, and at the same time the powder outlet blocking part 4 blocks the powder outlet channel 31, at this time the capsule cavity 11 can hold the capsule coffee 200, and the piercing component 5 is used for piercing and brewing; or the driving device 21 can make the piercing component 5 extend out of the capsule cavity 11 through the cooperation of the first moving part 22 and the second moving part 23, and at the same time the powder outlet blocking part 4 opens the powder outlet channel 31, at this time the coffee powder ground by the grinding device 3 can enter the capsule cavity 11 through the powder outlet channel 31 for brewing. Therefore, the coffee machine 100 can select the operations of grinding beans, brewing coffee powder and brewing capsule coffee 200 according to actual needs, and can integrate the operations of grinding beans, brewing coffee powder and brewing capsule coffee 200 into one, thereby improving the versatility of the coffee machine 100. The capsule coffee 200 is automatically punctured by the puncturing component 5, which can effectively avoid the problem of insufficient capsule puncture and easy bounce after puncture.
