In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0146] It should be noted that the "up", "down", "left", "right" and other directional words described in the embodiments of the present application are described from the angle shown in the drawings, and should not be understood as a limitation on the embodiments of the present application. In addition, in the context, it should also be understood that when referring to an element connected to another element "on" or "under", it can not only be directly connected to another element "on" or "under", but also indirectly connected to another element "on" or "under" through an intermediate element.

[0147] As Figure 1As shown, this application provides a coffee machine that can be used for daily household use and can also be carried outdoors. The coffee machine includes a main body 1, a grinding component 2, and a brewing component 3. Figure 2 As shown, the main body 1 includes a base 11 and a connecting portion 12 disposed on the top of the base 11. The connecting portion 12 includes a first connecting groove 121 and a second connecting groove 122. Along the Z-axis of the coffee machine, the first connecting groove 121 is located above the second connecting groove 122. The grinding assembly 2 is used to grind coffee beans or other ingredients into powder, and the brewing assembly 3 is used to hold the ingredient powder (coffee powder or other brewing powder) and brew the ingredient powder. The grinding assembly 2 is slidably connected to the other of the first connecting groove 121 and the second connecting groove 122, and the grinding assembly 2 can slide relative to the main body 1 to either a stored state or a grinding state; the brewing assembly 3 is slidably connected to the other of the first connecting groove 121 and the second connecting groove 122, and the brewing assembly 3 can slide relative to the main body 1 to either a stored state or a brewing state.

[0148] Specifically, in the first embodiment, the grinding component 2 can be slidably connected to the first connecting groove 121, and correspondingly, the brewing component 3 can be slidably connected to the second connecting groove 122. When the grinding component 2 slides relative to the first connecting groove 121 to... Figure 1 In the folded state shown, the projection of the grinding assembly 2 on the Z-axis of the coffee machine coincides with the projection of the base 11 on the Z-axis of the coffee machine, which helps to reduce the storage volume of the coffee machine; when the grinding assembly 2 slides relative to the first connecting groove 121 to Figure 3 In the grinding state shown, at least a portion of the projection of the grinding component 2 along the Z-axis of the coffee machine is outside the projection of the brewing component 3 along the Z-axis of the coffee machine. At this time, there is space below the grinding component 2 for placing a powder container, allowing the grinding component 2 to perform grinding operations. Further, the grinding component 2 includes a detachably connected grinding body 21 and a powder container 22. The grinding body 21 is used to grind coffee beans or other ingredients into powder. When the powder container 22 is separated from the grinding body 21, it can be placed below the grinding body 21 to hold the ground powder, enhancing the functionality of the coffee machine. When the grinding component 2 slides relative to the first connecting groove 121... Figure 1 In the folded state shown, the brewing assembly 3 restricts the powder container 22 from moving along the Z-axis of the coffee machine, meaning the powder container 22 cannot be disassembled, reducing the risk of loss; when the grinding assembly 2 slides relative to the first connecting groove 121 to... Figure 3In the grinding state shown, the powder receiving cup 22 is completely dislocated from the brewing assembly 3 along the axial direction Z of the coffee machine, i.e. the projection of the powder receiving cup 22 on the axial direction Z of the coffee machine is outside the projection of the brewing assembly 3 on the axial direction Z of the coffee machine, the powder receiving cup 22 can move downward along the axial direction Z of the coffee machine without interfering with the brewing assembly 3, i.e. the powder receiving cup 22 can be detached from the grinding body 21 to realize the grinding function of the coffee machine, at this time the powder receiving cup 22 can be placed below the grinding body 21 to contain the ground powder (the user can also place other containers below the grinding body 21 to contain the ground powder).

[0149] Similarly, when the brewing assembly 3 slides relative to the second connecting groove 122 to the Figure 1 In the storage state shown, the projection of the brewing assembly 3 on the axial direction Z of the coffee machine coincides with the projection of the base 11 on the axial direction Z of the coffee machine, which is beneficial to reduce the storage volume of the coffee machine; when the brewing assembly 3 slides relative to the second connecting groove 122 to the Figure 4 In the brewing state shown, at least part of the projection of the brewing assembly 3 on the axial direction Z of the coffee machine is outside the projection of the base 11 on the axial direction Z of the coffee machine, at this time the brewing assembly 3 has a space below which a liquid receiving container can be placed, and the brewing assembly 3 can perform brewing work. Further, the brewing assembly 3 comprises a brewing body 31 for containing food material powder and brewing the food material powder, and a liquid receiving cup 32 which, when separated from the brewing body 31, can be used to be placed below the brewing body 31 to contain the brewed liquid, thereby improving the functionality of the coffee machine. When the brewing assembly 3 slides relative to the second connecting groove 122 to the Figure 1 In the storage state shown, the base 11 restricts the movement of the liquid receiving cup 32 along the axial direction Z of the coffee machine, i.e. the liquid receiving cup 32 cannot be detached, which can reduce the risk of losing the liquid receiving cup 32; when the brewing assembly 3 slides relative to the second connecting groove 122 to the Figure 4 In the brewing state shown, the liquid receiving cup 32 is completely dislocated from the base 11 along the axial direction Z of the coffee machine, i.e. the projection of the liquid receiving cup 32 on the axial direction Z of the coffee machine is outside the projection of the base 11 on the axial direction Z of the coffee machine, the liquid receiving cup 32 can move downward along the axial direction Z of the coffee machine without interfering with the base 11, i.e. the liquid receiving cup 32 can be detached from the brewing body 31 to realize the brewing function of the coffee machine, at this time the liquid receiving cup 32 can be placed below the brewing body 31 to contain the brewed liquid (the user can also place other containers below the brewing body 31 to contain the brewed liquid).

[0150] Alternatively, as shown in Figure 5 and Figure 6As shown in the storage state of the second embodiment, the grinding assembly 2 can be in sliding connection with the second connecting groove 122, and correspondingly, the brewing assembly 3 can be in sliding connection with the first connecting groove 121. When the grinding assembly 2 is slid relative to the second connecting groove 122 to the grinding state as shown, the receiving cup 22 can be completely dislocated from the base 11 along the axial direction Z of the coffee machine, and the receiving cup 22 can be detached from the grinding body 21, so as to realize the grinding function of the coffee machine. Figure 5 As shown in the storage state of the second embodiment, the grinding assembly 2 can be in sliding connection with the second connecting groove 122, and correspondingly, the brewing assembly 3 can be in sliding connection with the first connecting groove 121. When the grinding assembly 2 is slid relative to the second connecting groove 122 to the grinding state as shown, the receiving cup 22 can be completely dislocated from the base 11 along the axial direction Z of the coffee machine, and the receiving cup 22 can be detached from the grinding body 21, so as to realize the grinding function of the coffee machine. Figure 7 As shown in the storage state of the second embodiment, the grinding assembly 2 can be in sliding connection with the second connecting groove 122, and correspondingly, the brewing assembly 3 can be in sliding connection with the first connecting groove 121. When the grinding assembly 2 is slid relative to the second connecting groove 122 to the grinding state as shown, the receiving cup 22 can be completely dislocated from the base 11 along the axial direction Z of the coffee machine, and the receiving cup 22 can be detached from the grinding body 21, so as to realize the grinding function of the coffee machine. Figure 5 As shown in the storage state of the second embodiment, the grinding assembly 2 can be in sliding connection with the second connecting groove 122, and correspondingly, the brewing assembly 3 can be in sliding connection with the first connecting groove 121. When the grinding assembly 2 is slid relative to the second connecting groove 122 to the grinding state as shown, the receiving cup 22 can be completely dislocated from the base 11 along the axial direction Z of the coffee machine, and the receiving cup 22 can be detached from the grinding body 21, so as to realize the grinding function of the coffee machine. Figure 8 As shown in the storage state of the second embodiment, the grinding assembly 2 can be in sliding connection with the second connecting groove 122, and correspondingly, the brewing assembly 3 can be in sliding connection with the first connecting groove 121. When the grinding assembly 2 is slid relative to the second connecting groove 122 to the grinding state as shown, the receiving cup 22 can be completely dislocated from the base 11 along the axial direction Z of the coffee machine, and the receiving cup 22 can be detached from the grinding body 21, so as to realize the grinding function of the coffee machine.

[0151] In summary, whether it is the coffee machine structure of the first embodiment or the coffee machine structure of the second embodiment, when the grinding assembly 2 and the brewing assembly 3 are both in the storage state, the projection of the grinding assembly 2 on the axial direction Z of the coffee machine, the projection of the brewing assembly 3 on the axial direction Z of the coffee machine, and the projection of the base 11 on the axial direction Z of the coffee machine all coincide, so that the coffee machine is in a state of minimum overall volume, and the space occupied by the coffee machine is smaller at this time, which is convenient for users to store and carry out.

[0152] Therefore, in the coffee machine provided by the embodiments of the present application, the main body 1, the grinding assembly 2 and the brewing assembly 3 are arranged along the axial direction Z of the coffee machine, which can reduce the size of the coffee machine in the length direction X and / or the width direction Y, so that the overall structure of the coffee machine is more compact, which is conducive to the miniaturization of the coffee machine. Moreover, the grinding assembly 2 and the brewing assembly 3 are respectively in sliding connection with the main body 1, which can improve the space utilization and space widening capability of the coffee machine, so that the volume of the coffee machine in the storage state is minimized, the storage space is saved, and it is convenient for users to store and carry out. For the coffee machine product, the packaging size can be reduced and the packaging cost can be reduced. Moreover, the grinding assembly 2 and the brewing assembly 3 are respectively in sliding connection with one of the first connecting groove 121 and the second connecting groove 122, so that the grinding assembly 2 and the brewing assembly 3 can be used independently of each other. When the user needs to use the grinding function of the coffee machine, the grinding assembly 2 is directly slid to the grinding state, and when the user needs to use the brewing function of the coffee machine, the brewing assembly 3 is directly slid to the brewing state, which is more convenient to operate.

[0153] It should be noted that the grinding assembly 2 and the brewing assembly 3 can be respectively slid relative to the main body 1 along the length direction X of the coffee machine, or can be respectively slid relative to the main body 1 along the width direction Y of the coffee machine, and the present embodiment does not limit this. Next, the specific structure of the coffee machine will be introduced by taking the grinding assembly 2 and the brewing assembly 3 as examples which can be respectively slid relative to the main body 1 along the length direction X of the coffee machine:

[0154] As shown in Figure 9 The connecting portion 12 includes a top wall 123, a first side wall 124 and a second side wall 125 which are oppositely arranged along the width direction Y of the coffee machine, and the top wall 123, the first side wall 124 and the second side wall 125 form a containing space with the top of the main body 1, and the two ends of the containing space along the length direction X of the coffee machine are in communication with the outside, so that the grinding assembly 2 and the brewing assembly 3 can be slid outward along the length direction X of the coffee machine. The connecting portion 12 further includes a partition plate 126 arranged in the containing space, and the two ends of the partition plate 126 are fixedly connected with the first side wall 124 and the second side wall 125 along the width direction Y of the coffee machine, so as to divide the connecting portion 12 into a first connecting groove 121 and a second connecting groove 122. This structure is relatively simple and convenient to manufacture, and by changing the position of the partition plate 126 along the axial direction Z of the coffee machine, the height of the first connecting groove 121 and the second connecting groove 122 can be adjusted to adapt to grinding assemblies 2 and brewing assemblies 3 of different height sizes, thereby improving the versatility of the connecting portion 12. In addition, the partition plate 126 can cooperate with the top wall 123 to limit the movement of the grinding assembly 2 or the brewing assembly 3 in the first connecting groove 121 along the axial direction Z of the coffee machine, and to support the assembly; the partition plate 126 can also cooperate with the top of the base 11 to limit the movement of the brewing assembly 3 or the grinding assembly 2 in the second connecting groove 122 along the axial direction Z of the coffee machine, that is, the partition plate 126 is beneficial to improve the stability of the grinding assembly 2 and the brewing assembly 3.

[0155] Among them, the grinding assembly 2 and the brewing assembly 3 can move in the same direction along the length direction X of the coffee machine, or can move in opposite directions along the length direction X of the coffee, and the present embodiment does not limit this.

[0156] Combined Figure 2 and Figure 9As shown, when the grinding assembly 2 is in sliding connection with the first connecting groove 121, one of the grinding body 21 and the first connecting groove 121 is provided with a first limiting protrusion 101, and the other is provided with a first sliding groove 102 extending along the length direction X of the coffee machine. The first sliding groove 102 and the first limiting protrusion 101 are in sliding fit, the first limiting protrusion 101 can guide the sliding process of the grinding assembly 2 to improve the sliding stability of the grinding assembly 2; the first limiting protrusion 101 can also limit the grinding assembly 2 from continuing to move along the length direction X of the coffee machine when abutting against the end of the first sliding groove 102, preventing the grinding assembly 2 from being pulled out of the first connecting groove 121. Among them, the two side inner walls of the first connecting groove 121 along the width direction Y of the coffee machine can be used to set the first limiting protrusion 101 or the first sliding groove 102, to further improve the sliding stability of the grinding assembly 2.

[0157] Correspondingly, one of the brewing body 31 and the second connecting groove 122 is provided with a second limiting protrusion 103, and the other is provided with a second sliding groove 104 extending along the length direction X of the coffee machine. The second sliding groove 104 and the second limiting protrusion 103 are in sliding fit, the second limiting protrusion 103 can guide the sliding process of the brewing assembly 3 to improve the sliding stability of the brewing assembly 3; the second limiting protrusion 103 can also limit the brewing assembly 3 from continuing to move along the length direction X of the coffee machine when abutting against the end of the second sliding groove 104, preventing the brewing assembly 3 from being pulled out of the second connecting groove 122. Among them, the two side inner walls of the second connecting groove 122 along the width direction Y of the coffee machine can be used to set the second limiting protrusion 103 or the second sliding groove 104, to further improve the sliding stability of the brewing assembly 3.

[0158] Similarly, in combination with Figure 6 and Figure 10As shown, when the grinding assembly 2 is in sliding connection with the second connecting groove 122, one of the grinding body 21 and the second connecting groove 122 is provided with the first limiting protrusion 101, and the other is provided with the first sliding groove 102 extending along the length direction X of the coffee machine. The first sliding groove 102 is in sliding connection with the first limiting protrusion 101, and the first limiting protrusion 101 can guide and limit the grinding assembly 2, so as to improve the sliding stability of the grinding assembly 2 and prevent the grinding assembly 2 from being pulled out of the second connecting groove 122. The two side inner walls of the second connecting groove 122 along the width direction Y of the coffee machine can be used to set the first limiting protrusion 101 or the first sliding groove 102. One of the brewing body 31 and the first connecting groove 121 is provided with the second limiting protrusion 103, and the other is provided with the second sliding groove 104 extending along the length direction X of the coffee machine. The second sliding groove 104 is in sliding connection with the second limiting protrusion 103, and the second limiting protrusion 103 can guide and limit the brewing assembly 3, so as to improve the sliding stability of the brewing assembly 3 and prevent the brewing assembly 3 from being pulled out of the first connecting groove 121. The two side inner walls of the first connecting groove 121 along the width direction Y of the coffee machine can be used to set the second limiting protrusion 103 or the second sliding groove 104.

[0159] As shown in Figure 4 and Figure 11 The base 11 includes a base shell 1101, a water tank 4, a water pump 6 and a heating device 5 installed in the base shell 1101. The water tank 4 is of an open structure and includes a tank body 41 and a tank cover 43. The tank body 41 is used to store liquid and is provided with a water outlet 411 at the bottom. The user can add liquid to the tank body 41 from the top. The tank cover 43 is fastened to the tank body 41. The heating device 5 includes a water inlet end 51 and a water outlet end 52. The water outlet end 52 is used to communicate with the water pipe 313 in the brewing body 31. The water pump 6 communicates with the water inlet end 51 and the water outlet 411 respectively, and is used to pump the liquid in the water tank 4 into the heating device 5 for heating, and also to increase the pressure of the liquid in the heating device 5, so as to ensure that the liquid can flow smoothly from the water inlet end 51 to the water outlet end 52, thereby increasing the flow speed of the liquid and improving the heating efficiency of the coffee machine. The liquid heated by the heating device 5 flows to the water pipe 313 to realize the brewing function of the coffee machine. The coffee machine provided with the heating device 5 can be used in an environment without hot water, which is more convenient and practical, and can improve the user's experience.

[0160] In the axial direction Z of the coffee machine, the water outlet end 52 is located above the water inlet end 51, that is, the heating device 5 adopts a bottom-in top-out mode, which is beneficial to the discharge of air in the heating device 5 and improves the heating efficiency. Moreover, the bottom-in top-out mode can make the liquid stay in the heating device 5 for a longer time and be heated more fully.

[0161] As shown in Figure 11As shown, the base shell 1101 is further provided with a power panel 7 and a power box 71, the power panel 7 is used to convert the external input alternating current into direct current required by the internal electrical devices, and is electrically connected with the internal electrical devices (such as the heating device 5, the water pump 6, etc.) to supply power to the electrical devices. The base 11 further comprises a base bottom cover 1102 fixedly connected with the base shell 1101, and the power box 71 can form an installation space with the base bottom cover 1102, so as to install the power panel 7 in the installation space. The base shell 1101 is further provided with a battery 8, which is used to supply power to the internal electrical devices (such as the water pump 6) in the absence of external power supply, so that the coffee machine is more convenient for users to carry out and use.

[0162] Specifically, the power box 71 has a first mounting portion 711 and a second mounting portion 712 distributed along the axial direction Z of the coffee machine, one of the heating device 5 and the power panel 7 is mounted on the first mounting portion 711, and the other is mounted on the second mounting portion 712, that is, the power box 71 can realize the integrated arrangement of the heating device 5 and the power panel 7, which is beneficial to save the internal space of the base 11, and can also shorten the distance between the heating device 5 and the power panel 7, which is beneficial to reduce the length of the connecting line. As Figure 4 As shown, the heating device 5 has a cylindrical structure, and the first mounting portion 711 or the second mounting portion 712 is provided with an annular groove corresponding to the heating device 5, and the bottom of the heating device 5 is mounted in the annular groove, which can limit the movement or deviation of the heating device 5 along its radial direction X, further improving the installation stability of the heating device 5.

[0163] As Figure 12 As shown, the water tank 4 further comprises a heating film 42 covering the outer bottom wall of the tank body 41, which is used to heat the liquid in the tank body 41. The heating film 42 has a small volume, which is beneficial to save the internal space of the base 11, and the heating film 42 is electrically connected with the battery 8, which can be used in the case of weak electricity, and is more convenient for users to carry out and use the coffee machine, which expands the use scene of the coffee machine.

[0164] When the brewing assembly 3 is heated by external power supply (i.e. strong electricity), the water pump 6 can deliver the normal temperature liquid in the water tank 4 to the heating device 5, and then to the water pipe 313 after heating; when the brewing assembly 3 is heated by the battery 8 (i.e. weak electricity), the heating film 42 is used to heat the liquid in the water tank 4, and the water pump 6 is used to deliver the heated liquid to the water pipe 313 through the heating device 5.

[0165] As Figure 13As shown, the brewing body 31 comprises a brewing shell 311, a brewing upper cover 312 connected with the brewing shell 311, and a control board 314 installed inside the brewing shell 311, the control board 314 is electrically or signal connected with the power board 7 and supplies power for the control board 314, the brewing upper cover 312 is provided with a control panel 312b, the control board 314 can be electrically or signal connected with the control panel 312b and internal electrical appliances (such as the heating device 5, the water pump 6, etc.) of the coffee machine, after the user touches the operation panel 312b, the control board 314 can receive the corresponding signal and control the corresponding electrical appliances to open or close according to the corresponding signal, so as to realize different functions of the coffee machine.

[0166] For example, as shown in Figure 11 The water tank 4 further comprises a thermistor 44, the thermistor 44 can be sealed and installed at the bottom of the water tank 4 through a thermistor sealing ring 45, the heating film 42, the thermistor 44 and the water pump 6 are electrically or signal connected with the control board 314, when the user selects the brewing function by operating the control panel 312b, the control board 314 can control the heating film 42 to heat the liquid in the tank body 41, and monitor the temperature of the liquid in the tank body 41 through the thermistor 44, so that the control board 314 can close the heating film 42 and open the water pump 6 when the liquid reaches the preset temperature, so as to deliver the heated liquid to the water pipe 313 to complete the brewing.

[0167] As shown in Figure 4 and Figure 9 The top of the base shell 1101 is provided with a first through hole 111, and the bottom of the brewing shell 311 is provided with a second through hole 311a. When the brewing body 31 is slidably connected with the second connecting groove 122, Figure 4 The arrow direction in the figure is the flow path of the liquid, one end of the connecting water pipe for connecting the water outlet 52 and the water pipe 313 is communicated with the water outlet 52, and the other end is communicated with the water pipe 313 after passing through the first through hole 111 and the second through hole 311a in sequence. When the brewing assembly 3 is slidably connected with the second connecting groove 122, the distance between the heating device 5 and the water pipe 313 can be shortened, so as to shorten the water flow path, which is beneficial to shorten the length of the connecting water pipe, and correspondingly, a water pump 6 with smaller power can be used to achieve the effect of energy saving. In addition, the control board 314 is electrically connected with the power board 7 through the first connecting wire, one end of the first connecting wire is connected with the power board 7, and the other end is connected with the control board 314 after passing through the first through hole 111 and the second through hole 311a in sequence.

[0168] The first through hole 111 has a small size and can constrain and position the connecting water pipe and the first connecting wire; the second through hole 311a extends along the length direction X of the coffee machine, can reduce the abrasion of the connecting water pipe and the first connecting wire caused by the sliding of the brewing assembly 3, and is beneficial to prolong the service life of the connecting water pipe and the first connecting wire. The number of the first through hole 111 can be one, and the connecting water pipe and the first connecting wire pass through the same first through hole 111, or as shown in Figure 9 , the number of the first through hole 111 can be two, and the connecting water pipe and the first connecting wire pass through different first through holes 111.

[0169] The grinding body 21 includes a grinding upper cover 212 and a grinding shell 211 connected together, as shown in Figure 6 and Figure 8 , when the brewing body 31 is slidably connected with the first connecting groove 121, the grinding upper cover 212 is further provided with a third through hole 212a, and the bottom of the grinding shell 211 is further provided with a fourth through hole 211a extending along the length direction Y of the coffee machine. Figure 8 The arrow direction in the figure is the flow path of the liquid, one end of the connecting water pipe connecting the water outlet 52 and the water pipe 313 is communicated with the water outlet 52, and the other end is communicated with the water pipe 313 after passing through the first through hole 111, the fourth through hole 211a, the third through hole 212a and the second through hole 311a in sequence. One end of the first connecting wire connecting the control panel 314 and the power panel 7 is connected with the power panel 7, and the other end is connected with the control panel 314 after passing through the first through hole 111, the fourth through hole 211a, the third through hole 212a and the second through hole 311a in sequence. The number of the third through hole 212a can be one, and the connecting water pipe and the first connecting wire pass through the same third through hole 212a, or as shown in Figure 6 , the number of the third through hole 212a can be two, and the connecting water pipe and the first connecting wire pass through different third through holes 212a.

[0170] Similarly, the first through hole 111 and the third through hole 212a can constrain and position the connecting water pipe and the first connecting wire; the second through hole 311a and the fourth through hole 211a respectively extend along the length direction X of the coffee machine, can reduce the abrasion of the connecting water pipe and the first connecting wire caused by the sliding of the brewing assembly 3 and the grinding assembly 2, and are beneficial to prolong the service life of the connecting water pipe and the first connecting wire.

[0171] In addition, as shown in Figure 10 , when the brewing body 31 is slidably connected with the first connecting groove 121, one or two notch portions 126a can be arranged on the partition plate 126 to avoid the connecting water pipe and the first connecting wire, and also can constrain the connecting water pipe and the first connecting wire to a certain extent.

[0172] As shown in Figure 13 , the brewing body 31 comprises a detachably connected body part 3101 and a brewing part 3102, the body part 3101 comprises a brewing upper cover 312, a brewing shell 311, a water passing pipe 313 and a control panel 314, and the brewing part 3102 is used for containing food material powder to be brewed. When the brewing assembly 3 is in the storage state, the liquid receiving cup 32 is connected to the body part 3101, and the brewing part 3102 is contained in the liquid receiving cup 32. When the brewing assembly 3 is rotated to the state that the liquid receiving cup 32 is completely dislocated from the base 11 along the axial direction Z of the coffee machine, the brewing part 3102 can also be detached from the body part 3101 after the liquid receiving cup 32 is detached from the body part 3101, which facilitates the user to fill the food material powder into the brewing part 3102 or pour the food material powder out, and also facilitates the cleaning of the brewing part 3102. The brewing part 3102 can be threadedly connected to the brewing shell 311 or buckled, which is not limited in the embodiment.

[0173] As shown in Figure 14 , the brewing part 3102 comprises a detachably connected upper cover 3102a and lower cover 3102b, the upper cover 3102a is provided with a through hole in communication with the water passing pipe 313, and the lower cover 3102b is provided with a water outlet nozzle in communication with the outside, and the brewed liquid flows out through the water outlet nozzle. The upper cover 3102a and the water passing pipe 313 are sealingly connected through a first sealing ring 3102c, a sealing ring gasket 3102d, a second sealing ring 3102e, a sealing gasket 3102f and a sealing gasket pressing plate 3102g; the lower cover 3102b is provided with a powder bowl 3102i, the powder bowl 3102i is stably connected to the lower cover 3102b through a limiting snap spring 3102j, and the food material powder to be brewed is placed in the powder bowl 3102i; a filter screen 3102m is fixedly installed between the powder bowl 3102i and the water outlet nozzle through a filter screen pressing plate 3102k, and the filter screen 3102m is used for filtering the food material powder; a water distribution screen plate 3102h can also be arranged between the sealing gasket pressing plate 3102g and the powder bowl 3102i, so that the liquid in the water passing pipe 313 can uniformly flow to the powder bowl 3102i, improving the uniformity of brewing.

[0174] As shown in Figure 15As shown, the grinding upper cover 212 is formed with a material box 212b for containing food materials to be ground, the bottom of the material box 212b is communicated with the grinding shell 211, and the upper portion of the material box 212b is provided with a material box cover 213 which is detachably connected to the material box 212b. After the user opens the material box cover 213, the user can add food materials to be ground to the material box 212b, and the use is more convenient. The grinding shell 211 is installed with a driving device 23 and a grinding assembly 24. The grinding assembly 24 includes a static grinding head 241 and a dynamic grinding head 242. The static grinding head 241 is fixedly connected to the grinding shell 211 through a static grinding head pressing plate 241b. The dynamic grinding head 242 can rotate relative to the static grinding head 241 under the driving of the driving device 23, so as to grind the food materials together with the static grinding head 241. The ground food material powder can fall to the outside through the gap between the static grinding head 241 and the dynamic grinding head 242.

[0175] Specifically, in combination with Figure 3 As shown, the driving device 23 includes a driving member 231 and a transmission assembly 232. The transmission assembly 232 includes a transmission shaft 232d, a driving pulley 232a, a driven pulley 232b, and a synchronous belt 232c which is wound around the driving pulley 232a and the driven pulley 232b. The driving pulley 232a is sleeved on the driving shaft of the driving member 231. The driven pulley 232b is connected to the dynamic grinding head 242 through the transmission shaft 232d. The transmission shaft 232d is rotatably connected to the grinding upper cover 212 through an upper bearing 232e and an upper gasket 232f, and is rotatably connected to the grinding shell 211 through a lower bearing 232g and a lower gasket 232h. The transmission shaft 232d can drive the dynamic grinding head 242 to rotate synchronously under the driving of the driven pulley 232b, so that the dynamic grinding head 242 can rotate relative to the static grinding head 241 under the driving of the driving member 231. The driving member 231 and the dynamic grinding head 242 are distributed along the length direction X of the coffee machine. The driving member 231 is reasonably arranged in the internal space of the grinding shell 211. Compared with the mode that the driving member 231 directly drives the dynamic grinding head 242, the size of the grinding assembly 2 in the axial direction Z of the coffee machine can be reduced, and the compactness of the structure of the coffee machine is improved. The driving member 231 can be a direct current motor, a stepping motor or other driving equipment, and the present embodiment does not limit this.
