The coffee machine comprises a main body 1, a first assembly and a second assembly. Along the axial direction Z of the coffee machine, the top of the second assembly is rotatably connected to the bottom of the first assembly, and the bottom of the second assembly is rotatably connected to the main body 1.

When the second assembly is in the storage state, the second assembly is aligned with the main body 1 along the axial direction Z of the coffee machine, and the second assembly does not have the first material receiving space 107 below. The first assembly has a storage state and a working state. When the first assembly is in the working state, the first assembly is misaligned with the second assembly along the axial direction Z of the coffee machine, so as to form a second material receiving space 108 below the first assembly. When the first assembly is in the storage state, the first assembly is aligned with the second assembly along the axial direction Z of the coffee machine, and the first assembly does not have the second material receiving space 108 below. One of the first assembly and the second assembly is a grinding assembly 2, and the other is a brewing assembly 3.

As Figure 3 As shown, when the grinding assembly 2 is in the working state, at least part of the projection of the grinding assembly 2 in the axial direction Z of the coffee machine is located outside the projection of the brewing assembly 3 in the axial direction Z of the coffee machine, at this time, the lower part of the grinding assembly 2 has a second material receiving space 108 capable of placing a powder receiving container, and the grinding assembly 2 can perform grinding work; as Figure 1 As shown, when the grinding assembly 2 is in the storage state, the projection of the grinding assembly 2 in the axial direction Z of the coffee machine coincides with the projection of the brewing assembly 3 in the axial direction Z of the coffee machine, and the lower part of the grinding assembly 2 does not have the second material receiving space 108, at this time, it is beneficial to reduce the storage volume of the coffee machine. Moreover, when the grinding assembly 2 and the brewing assembly 3 are both in Figure 1 As shown, when the grinding assembly 2 is in the storage state, the projection of the grinding assembly 2 in the axial direction Z of the coffee machine coincides with the projection of the brewing assembly 3 in the axial direction Z of the coffee machine, and the lower part of the grinding assembly 2 does not have the second material receiving space 108, at this time, it is beneficial to reduce the storage volume of the coffee machine. Moreover, when the grinding assembly 2 and the brewing assembly 3 are both in

[0179] In another embodiment, as shown in Figure 17 and Figure 18 The first assembly is the brewing assembly 3, and the second assembly is the grinding assembly 2, that is, the brewing assembly 3, the grinding assembly 2 and the main body 1 are arranged in sequence along the axial direction Z of the coffee machine, and along the axial direction Z of the coffee machine, the top of the grinding assembly 2 is rotatably connected to the bottom of the brewing assembly 3, and the bottom of the grinding assembly 2 is rotatably connected to the main body 1. In this embodiment, the grinding assembly 2 can rotate relative to the main body 1 and the brewing assembly, as shown in Figure 19 As shown, when the grinding assembly 2 is in the working state, at least part of the projection of the grinding assembly 2 in the axial direction Z of the coffee machine is located outside the projection of the main body 1 in the axial direction Z of the coffee machine, at this time, the lower part of the grinding assembly 2 has a first material receiving space 107 capable of placing a material receiving container, and the grinding assembly 2 can perform grinding work; as Figure 17 As shown, when the grinding assembly 2 is in the storage state, the projection of the grinding assembly 2 in the axial direction Z of the coffee machine coincides with the projection of the main body 1 in the axial direction Z of the coffee machine, and the lower part of the grinding assembly 2 does not have the first material receiving space 107, at this time, it is beneficial to reduce the storage volume of the coffee machine. As Figure 19As shown, when the brewing assembly 3 is in the working state, at least part of the projection of the brewing assembly 3 in the axial direction Z of the coffee machine is located outside the projection of the grinding assembly 2 in the axial direction Z of the coffee machine, at this time, the lower part of the brewing assembly 3 has a second material receiving space 108 capable of placing a liquid receiving container, the brewing assembly 3 can perform brewing work, the brewing assembly 3 is located below the grinding assembly 2, is closer to the desktop, and when the user receives the brewed liquid, the liquid is not easy to splash, thereby reducing the risk of high-temperature liquid scalding the user. As shown in Figure 17 As shown, when the brewing assembly 3 is in the working state, at least part of the projection of the brewing assembly 3 in the axial direction Z of the coffee machine is located outside the projection of the grinding assembly 2 in the axial direction Z of the coffee machine, at this time, the lower part of the brewing assembly 3 has a second material receiving space 108 capable of placing a liquid receiving container, the brewing assembly 3 can perform brewing work, the brewing assembly 3 is located below the grinding assembly 2, is closer to the desktop, and when the user receives the brewed liquid, the liquid is not easy to splash, thereby reducing the risk of high-temperature liquid scalding the user. As shown in Figure 17 As shown, when the brewing assembly 3 is in the working state, at least part of the projection of the brewing assembly 3 in the axial direction Z of the coffee machine is located outside the projection of the grinding assembly 2 in the axial direction Z of the coffee machine, at this time, the lower part of the brewing assembly 3 has a second material receiving space 108 capable of placing a liquid receiving container, the brewing assembly 3 can perform brewing work, the brewing assembly 3 is located below the grinding assembly 2, is closer to the desktop, and when the user receives the brewed liquid, the liquid is not easy to splash, thereby reducing the risk of high-temperature liquid scalding the user. As shown in

[0180] The embodiments of the present application arrange the grinding assembly 2, the brewing assembly 3 and the main body 1 in a structure arranged along the axial direction Z of the coffee machine, which can reduce the size of the coffee machine in the radial direction X, so that the overall structure of the coffee machine is more compact. By arranging one of the brewing assembly 3 and the grinding assembly 2 to be rotatably connected relative to the other and the main body 1, the space utilization and space widening capability of the coffee machine can be improved, so that the volume of the coffee machine in the storage state is minimized, the storage space is saved, and the user can conveniently store and carry out. For the coffee machine product, the packaging size and cost can be reduced. Moreover, by rotating the assembly located in the middle along the axial direction Z of the coffee machine, the grinding function and the brewing function of the coffee machine can be realized at the same time, which simplifies the operation steps of the coffee machine, facilitates the daily use of the user, and is helpful to improve the user experience.

[0181] Further, the first assembly includes a first body and a first material receiving cup which are detachably connected, and / or the second assembly includes a second body and a second material receiving cup which are detachably connected. In the first embodiment described above, the first body is the grinding body 21, the first material receiving cup is the powder receiving cup 22, and / or the second body is the brewing body 31, and the second material receiving cup is the liquid receiving cup 32; in the second embodiment described above, the first body is the brewing body 31, the first material receiving cup is the liquid receiving cup 32, and / or the second body is the grinding body 21, and the second material receiving cup is the powder receiving cup 22. The grinding body 21 is used to grind coffee beans or other food materials into powder, and when the powder receiving cup 22 is separated from the grinding body 21, it can be used to place below the grinding body 21 to contain the ground powder. The brewing body 31 is used to contain food material powder (coffee powder or other brewed powder), and when the liquid receiving cup 32 is separated from the brewing body 31, it can be used to place below the brewing body 31 to contain the brewed liquid.

[0182] Next, the coffee machine in each of the above two embodiments will be described in detail. In the first embodiment, as shown in Figure 1 When the brewing assembly 3 is in the storage state, the main body 1 can restrict the liquid receiving cup 32 from moving along the axial direction Z of the coffee machine, i.e., the liquid receiving cup 32 cannot be detached, thereby reducing the risk of losing the liquid receiving cup 32; as shown in Figure 3 When the brewing assembly 3 is in the working state, the liquid receiving cup 32 is completely misaligned with the main body 1 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 located outside the projection of the main body 1 on the axial direction Z of the coffee machine, the liquid receiving cup 32 can be detached from the brewing body 31, the liquid receiving cup 32 can move downward along the axial direction Z of the coffee machine without interfering with the main body 1, and 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). As shown in Figure 1 When the grinding assembly 2 is in the storage state, the brewing body 31 can restrict the powder receiving cup 22 from moving along the axial direction Z of the coffee machine, i.e., the powder receiving cup 22 cannot be detached, thereby reducing the risk of losing the powder receiving cup 22; as shown in Figure 3 When the grinding assembly 2 is in the working state, the brewing body 31 is completely misaligned with the powder receiving cup 22 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 located outside the projection of the brewing body 31 on the axial direction Z of the coffee machine, the powder receiving cup 22 can be detached from the grinding body 21, and 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). As shown in Figure 4 When the brewing assembly 3 is in the working state and the grinding assembly 2 is in the working state by only rotating the brewing assembly 3, a second material receiving space 108 is formed between the grinding body 21 and the main body 1, and the powder receiving cup 22 can move downward along the axial direction Z of the coffee machine in the second material receiving space 108 without interfering with the brewing body 31.

[0183] In a specific embodiment, as shown in Figure 5As shown, the grinding body 21 comprises a grinding shell 211, the brewing body 31 comprises a brewing upper cover 311, one of the grinding shell 211 and the brewing upper cover 311 is provided with the first rotating shaft 101, and the other is provided with the first rotating connecting portion 102 which is rotationally connected with the first rotating shaft 101. The first rotating connecting portion 102 is a cylindrical structure extending along the axial direction Z of the coffee machine, the first rotating shaft 101 extends along the axial direction Z of the coffee machine, at least a part of the first rotating shaft 101 is located in the cylindrical structure, the first rotating shaft 101 can rotate relative to the first rotating connecting portion 102, and the first rotating connecting portion 102 can also rotate around the first rotating shaft 101, so that any one of the grinding assembly 2 and the brewing assembly 3 rotates relative to the other. The connection structure of the first rotating shaft 101 and the first rotating connecting portion 102 is relatively simple, and the internal space of the grinding assembly 2 and the brewing assembly 3 is fully utilized without additional space occupation, which is conducive to reducing the volume of the coffee machine. In addition, as Figure 5 As shown, when the first rotating connecting portion 102 is connected with the first rotating shaft 101, the grinding shell 211 can be lapped on the top wall of the brewing upper cover 311, so as to stably place the grinding assembly 2 above the brewing assembly 3, which is conducive to improving the stability of the coffee machine.

[0184] In this embodiment, the grinding assembly 2 can also rotate relative to the brewing assembly 3 and the main body 1. When the grinding assembly 2 rotates relative to the brewing assembly 3 to completely dislocate the receiving cup 22 and the brewing body 31 along the axial direction Z of the coffee machine, the receiving cup 22 can be detached from the grinding body 21 to realize the grinding function of the coffee machine. The grinding assembly 2 and the brewing assembly 3 are independent of each other, and the user can directly rotate the grinding assembly 2 when using the grinding function of the coffee machine, and directly rotate the brewing assembly 3 when using the brewing function of the coffee machine, so that the two function assemblies do not affect each other. Moreover, by arranging the grinding assembly 2 to be rotatable, when the grinding assembly 2 is completely dislocated from the main body 1 along the axial direction Z of the coffee machine, the height difference between the grinding body 21 and the table top is large enough, so that other higher containers can be used to hold the ground powder, thereby improving the applicability of the coffee machine.

[0185] As Figure 5As shown, the brewing body 31 further comprises a brewing shell 312 connected with the brewing upper cover 311, and the main body 1 comprises a main body shell 12, one of the brewing shell 312 and the main body shell 12 is provided with the second rotating shaft 103, and the other is provided with the second rotating connection part 104 rotationally connected with the second rotating shaft 103. The second rotating connection part 104 is a cylindrical structure extending along the axial direction Z of the coffee machine, the second rotating shaft 103 extends along the axial direction Z of the coffee machine, and at least part of the second rotating shaft 103 is located in the cylindrical structure, and the second rotating shaft 103 can rotationally cooperate with the second rotating connection part 104 to enable the brewing body 31 to rotate relative to the main body 1. Similarly, the connection structure of the second rotating shaft 103 and the second rotating connection part 104 is relatively simple, which is conducive to reducing the volume of the coffee machine and improving the stability of the coffee machine.

[0186] Further, as shown in the drawings, Figure 5 The grinding body 21 further comprises a first limiting plate 212 fixedly connected with the first rotating shaft 101, and at least part of the first rotating connection part 102 is clamped between the first limiting plate 212 and the first rotating shaft 101 along the axial direction Z of the coffee machine, so as to limit the movement of the grinding assembly 2 relative to the brewing assembly 3 along the axial direction Z of the coffee machine, thereby improving the stability of the rotational connection between the grinding assembly 2 and the brewing assembly 3. And / or, the main body 1 further comprises a second limiting plate 13 fixedly connected with the second rotating shaft 103, and at least part of the second rotating connection part 104 is clamped between the second limiting plate 13 and the second rotating shaft 103 along the axial direction Z of the coffee machine, so as to limit the movement of the brewing assembly 3 relative to the main body 1 along the axial direction Z of the coffee machine, thereby improving the stability of the rotational connection between the main body 1 and the brewing assembly 3. Therefore, when the first limiting plate 212 and the second limiting plate 13 are provided at the same time, the stability of the overall structure of the coffee machine can be improved.

[0187] Among them, the first limiting plate 212 and the first rotating shaft 101, the second limiting plate 13 and the second rotating shaft 103 can be fixedly connected by bolts or other fasteners, which are not limited in the embodiment.

[0188] Further, as shown in the drawings, Figure 6 The first rotating shaft 101 is provided with a protruding first rotation stopping part 101a, and the first rotating connection part 102 is provided with a protruding first rotation stopping cooperation part for abutting and cooperating with the first rotation stopping part 101a during relative rotation of the first rotating shaft 101 and the first rotating connection part 102, so as to limit the relative rotation of the brewing assembly 3 and the grinding assembly 2, so that the grinding assembly 2 and the brewing assembly 3 can be positioned during rotation, that is, the grinding assembly 2 and the brewing assembly 3 can be kept in a stable state at a specific relative position, which is conducive to improving the stability of the grinding assembly 2 and the brewing assembly 3 in their working state. Specifically, as shown in the drawings, Figure 6As shown, the first rotating connecting part 102 may have a first rotating engagement groove 102a, and a first anti-rotation engagement part is disposed in the first rotating engagement groove 102a. During the relative rotation of the grinding component 2 and the brewing component 3, the first anti-rotation part 101a slides in engagement with the first rotating engagement groove 102a. When the first anti-rotation part 101a abuts against the first anti-rotation engagement part, the grinding component 2 and the brewing component 3 stop rotating relative to each other. Alternatively, the first rotating shaft 101 may have a first rotating engagement groove 102a, and the first anti-rotation part 101a may be located in the first rotating engagement groove 102a, with the first anti-rotation engagement part sliding in engagement with the first rotating engagement groove 102a.

[0189] And / or, such as Figure 7 As shown, the second rotating shaft 103 is provided with a protruding second anti-rotation part 103a, and the second rotating connecting part 104 is provided with a protruding second anti-rotation mating part. The second anti-rotation mating part is used to abut against the second anti-rotation part 103a during the relative rotation of the second rotating shaft 103 and the second rotating connecting part 104, so as to restrict the rotation of the brewing component 3 relative to the main body 1, so that the brewing component 3 and the main body 1 can maintain a stable state in a specific relative position, which also helps to improve the stability of the brewing component 3 in its own working state. Similarly, as Figure 7 As shown, the second rotating connecting part 104 may have a second rotating mating groove 104a, and a second anti-rotation mating part is disposed within the second rotating mating groove 104a. During the rotation of the brewing assembly 3 relative to the main body 1, the second anti-rotation part 103a slides within the second rotating mating groove 104a until the second anti-rotation part 103a abuts against the second anti-rotation mating part, at which point the brewing assembly 3 stops rotating. Alternatively, the second rotating shaft 103 may have a second rotating mating groove 104a, with the second anti-rotation part 103a located within the second rotating mating groove 104a, and the second anti-rotation mating part sliding within the second rotating mating groove 104a. When both the first anti-rotation part 101a and the first anti-rotation mating part, and the second anti-rotation part 103a and the second anti-rotation mating part are simultaneously provided, the overall stability of the coffee machine during operation can be improved.

[0190] Specifically, for the brewing component 3, by adjusting the relative positions of the second anti-rotation part 103a and the second anti-rotation mating part in the circumferential direction of the second rotating shaft 103, the brewing component 3 can achieve unidirectional or bidirectional rotation. For example, as shown in Figure 8(a), when the brewing component 3 can rotate clockwise or counterclockwise from its initial position, the maximum angle α1 of its clockwise rotation and the maximum angle α2 of its counterclockwise rotation can be equal or unequal, but neither should exceed 300°; as shown in Figure 8(b), the brewing component 3 can rotate unidirectionally from its initial position in either the clockwise or counterclockwise direction, but the maximum angle β of the rotation should not exceed 360°.

[0191] Similarly, by adjusting the relative positions of the first anti-rotation part 101a and the first anti-rotation mating part in the circumferential direction of the first rotating shaft 101, the grinding component 2 can be made to rotate unidirectionally or bidirectionally relative to the brewing component 3, which will not be elaborated here. Of course, the relative positional relationship between the first anti-rotation part 101a and the first anti-rotation mating part in the circumferential direction of the first rotating shaft 101 can also limit the rotation effect of the brewing component 3.

[0192] In one specific implementation, such as Figure 9 As shown, the main body casing 12 includes a first part 121 and a second part 122 distributed radially X along the coffee machine. A water tank 4 and a heating device 5 are also disposed inside the main body casing 12. The water tank 4 is installed in the first part 121, and the heating device 5 is installed in the second part 122. The water tank 4 has an open structure, including a tank body 41 and a water tank cover 43. The tank body 41 is used to store liquid, and a water outlet 411 is provided at the bottom, allowing the user to add liquid from the top of the tank body 41. The water tank cover 43 is fastened to the tank body 41. The heating device 5 includes a water inlet 51 and a water outlet 52. The water outlet 52 is used to communicate with the water pipe 313 inside the brewing body 31, combined with… Figure 3 and Figure 5 As shown, the coffee machine also includes a water pump 6, which is connected to both the inlet 51 and the outlet 411. The water pump 6 draws liquid from the water tank 4 and sends it to the heating device 5 for heating. It also increases the pressure of the liquid within the heating device 5, ensuring smooth flow from the inlet 51 to the outlet 52, thereby accelerating the liquid flow and improving the coffee machine's heating efficiency. The heated liquid flows to the water pipe 313 to realize the coffee machine's brewing function. Coffee machines equipped with the heating device 5 can be used in environments without hot water, making them more convenient and practical, and enhancing the user experience.

[0193] Along the Z-axis of the coffee machine, the water outlet 52 is located above the water inlet 51, meaning the heating device 5 adopts a bottom-in, top-out configuration. This facilitates the expulsion of air from the heating device 5 and improves heating efficiency. Furthermore, the bottom-in, top-out configuration allows the liquid to remain in the heating device 5 for a longer time, resulting in more thorough heating.

[0194] Furthermore, the heating device 5 and the water pipe 313 can be connected by a flexible water pipe. In this embodiment, by placing the brewing component 3 between the main body 1 and the grinding component 2, the distance between the heating device 5 and the water pipe 313 can be shortened, thereby shortening the water flow path and shortening the length of the connecting water pipe. Accordingly, a smaller power water pump 6 can be used to achieve energy saving.

[0195] like Figure 9 As shown, the main body shell 12 is also equipped with a heating device insulation component and a heating device fixing plate 54, combined with Figure 5As shown, the top of the heating device heat insulation piece 53 is fixedly connected with the second part 122, the bottom of the heating device heat insulation piece 53 is fixedly connected with the heating device fixed plate 54, the heating device heat insulation piece 53 and the heating device fixed plate 54 enclose a containing space, and the heating device 5 is installed in the containing space. On the one hand, the heating device heat insulation piece 53 is sleeved on the outer periphery of the heating device 5, which can reduce heat loss of the heating device 5 and also reduce the influence of high temperature of the heating device 5 on other electrical devices and pipelines in the main body 1. On the other hand, the heating device heat insulation piece 53 and the heating device fixed plate 54 can jointly limit the movement of the heating device 5 in the axial direction Z of the coffee machine, thereby realizing stable installation of the heating device 5.

[0196] Specifically, the heating device 5 has a cylindrical structure, the heating device fixed plate 54 is provided with a corresponding annular groove 542, and the bottom of the heating device 5 is installed in the annular groove 542, so that the movement or deviation of the heating device 5 in the radial direction X is limited, thereby further improving the installation stability of the heating device 5. Of course, the bottom of the heating device 5 can also be fixedly connected with the annular groove by using bolts or other fasteners, which is not limited in the embodiment.

[0197] As shown in the figure, Figure 9 The main body 1 further comprises a main body bottom cover 14 fixedly connected with the main body shell 12, and the power supply box 71 can enclose a containing space with the main body bottom cover 14, so that the power supply board 7 is installed in the containing space. The main body shell 12 further comprises 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.

[0198] As shown in the figure, Figure 10 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 conducive to saving the internal space of the main body 1. Moreover, the heating film 42 is electrically connected with the battery 8, so that it can be used in the case of weak electricity, which is more convenient for users to carry out and use the coffee machine.

[0199] In the embodiment, when the brewing assembly 3 is heated by external power supply (i.e. in the case of 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 channel 313 after being heated. When the brewing assembly 3 is heated by the battery 8 (i.e. in the case of 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 channel 313 through the heating device 5.

[0200] AsFigure 11 As shown, the brewing assembly 3 further comprises a control panel 33 and a control panel heat insulation piece 34, the brewing upper cover 311 and the brewing shell 312 are fixedly connected along the axial direction Z of the coffee machine, the control panel 33 and the control panel heat insulation piece 34 can be clamped and fixed by the brewing upper cover 311 and the brewing shell 312, and the control panel heat insulation piece 34 is used for heat insulation to prevent the internal high-temperature environment of the coffee machine from affecting the normal work of the control panel 33. Specifically, the outer side wall of the control panel heat insulation piece 34 can be provided with several positioning portions 343 at intervals, which are used for cooperating with the structure on the inner wall of the brewing shell 312 to improve the installation stability of the control panel heat insulation piece 34 and prevent it from shaking.

[0201] The power panel 7 is electrically or signal connected with the control panel 33 and supplies power for the control panel 33, the brewing upper cover 311 is provided with a control panel 311a, the control panel 33 can be electrically or signal connected with the control panel 311a and the 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 311a, the control panel 33 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.

[0202] For example, as shown in Figure 9 The water tank 4 further comprises a thermistor 44, the thermistor 44 can be sealed and installed on 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 panel 33, when the user selects the brewing function by operating the control panel 311a, the control panel 33 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 panel 33 can close the heating film 42 and open the water pump 6 when the liquid reaches the preset temperature, thereby delivering the heated liquid to the water pipe 313 to complete the brewing.

[0203] As shown in Figure 2 and Figure 3 , the arrow direction in Figure 3 is the flow path of the liquid, the main body 1 has a first communication cavity 105, the first communication cavity 105 is used for communicating the brewing assembly 3 with the main body 1, the control panel heat insulation piece 34 is located directly above the first communication cavity 105, the control panel heat insulation piece 34 is provided with a notch portion 341, one end of the connecting pipe is communicated with the water outlet 411 of the heating device 5, and the other end is communicated with the water pipe 313 through the first communication cavity 105 and the notch portion 341. The notch portion 341 is not only used for avoiding and providing space for the connecting pipeline, but also can constrain the connecting pipeline to prevent it from moving excessively, which is conducive to shortening the length of the connecting pipeline and improving the stability of the connecting pipeline.

[0204] As shown in Figure 2 ,Figure 5 and Figure 11 As shown, the second rotating shaft 103 is formed on the top of the main body shell 12, the first connecting cavity 105 is located on the second rotating shaft 103, and the control board heat insulation component 34 is also provided with a first conduit 342.

The connecting wire between the power board 7 and the control board 33 passes through the hollow structure of the heating device 5 and the first conduit 342. The first conduit 342 is used to insulate the heat of the heating device 5, prevent the connecting wire from being damaged by high temperature, and also to constrain the connecting wire, prevent the connecting wire from moving excessively, which is beneficial to shortening the length of the connecting wire and improving the stability of the connecting wire.

[0205] In another implementation, such as Figure 12 As shown, the heating device 5 is installed on the outer wall or the inner wall of the housing 41. The water outlet 411 is connected to the water inlet 51 of the heating device 5, and the water pipe 313 is connected to the water outlet 52 of the heating device 5. That is, the heating device 5 and the water tank 4 can be integrated together, making the structure of the heating device 5 and the water tank 4 more compact and saving space inside the main body 1. In this example, the heating device insulation component 53 is sleeved on the outer wall of the integrated structure, and its top is fixedly connected to the main body shell 12, eliminating the need for a heating device fixing plate 54. Figure 12 As shown, when the integrated structure of the heating device 5 and the water tank 4 is installed in the first part 121, the second part 122 has more space in the axial Z direction of the coffee machine to install electrical components such as the power board 7, battery 8 and water pump 6, which is beneficial to further shorten the length of the connecting pipes and connecting wires.

[0206] In addition, in this embodiment, the water pump 6 can be used to connect the outlet 411 and the inlet 51, or to connect the outlet 52 and the water pipe 313, both of which can deliver the heated liquid to the water pipe 313.

The body part 301 includes a brewing top cover 311, a brewing outer shell 312, a water pipe 313, a control board 33, and a control board heat insulation component 34. The brewing part 302 is used to hold the food powder to be brewed. Figure 12As shown, when the brewing assembly 3 is in the retracted state, the receiving cup 32 is connected to the main body 301, and the brewing part 302 is housed within the receiving cup 32.

This allows the user to easily fill the brewing part 302 with food powder or pour it out, and also facilitates cleaning the brewing part 302. The brewing part 302 can be threadedly connected to the brewing housing 312 or snap-fit ​​connected; this embodiment does not impose any limitations on this.

[0208] like Figure 13 As shown, the brewing unit 302 includes a detachably connected upper cover 302a and a lower cover 302b. The top of the upper cover 302a is provided with a through hole that communicates with the water pipe 313, and the lower cover 302b is provided with a water outlet that communicates with the outside. The brewed liquid flows out through the water outlet. The upper cover 302a and the water pipe 313 are sealed together by a first sealing ring 302c, a sealing ring gasket 302d, a second sealing ring 302e, a sealing gasket 302f, and a sealing gasket pressure plate 302g. A powder bowl 302i is installed inside the lower cover 302b, and the powder bowl 302i is stably connected to the lower cover 302b by a limiting spring 302j. The food powder to be brewed is placed inside the powder bowl 302i. A filter screen 302m is fixedly installed between the powder bowl 302i and the water outlet by a filter screen pressure plate 302k. The filter screen 302m is used to filter the food powder. A water distribution plate 302h can also be installed between the sealing gasket pressure plate 302g and the powder bowl 302i to ensure that the liquid in the water pipe 313 flows evenly to the powder bowl 302i, improving the uniformity of brewing.

[0209] In one specific implementation, such as Figure 14 As shown, the grinding body 21 also includes a grinding cover 213, which is fixedly connected to the top of the grinding shell 211. A material box 213a is formed on the grinding cover 213. The material box 213a is used to hold the ingredients to be ground. The bottom of the material box 213a is connected to the grinding shell 211. A material box cover 215 is provided on the top of the material box 213a and is fastened to it. After the user opens the material box cover 215, he / she can add the ingredients to be ground into the material box 213a, making it more convenient to use. The grinding housing 211 is equipped with a drive device 23 and a grinding assembly 24. The grinding assembly 24 includes a stationary grinding head 241 and a moving grinding head 242. The stationary grinding head 241 is fixedly connected to the grinding housing 211 through a stationary grinding head pressure plate 241b. The moving grinding head 242 can rotate relative to the stationary grinding head 241 under the drive of the drive device 23, thereby grinding the food together with the stationary grinding head 241. The ground food powder can fall to the outside through the gap between the stationary grinding head 241 and the moving grinding head 242.

[0210] Specifically, in combinationFigure 4 As shown, the driving device 23 comprises a driving member 231 and a transmission assembly 232, the transmission assembly 232 comprising a transmission shaft 232d, a driving pulley 232a, a driven pulley 232b and a synchronous belt 232c wound around the driving pulley 232a and the driven pulley 232b, the driving pulley 232a being sleeved on a driving shaft of the driving member 231, the driven pulley 232b being connected with the movable grinding head 242 through the transmission shaft 232d, the transmission shaft 232d being rotatably connected with the grinding upper cover 213 through an upper bearing 232e and an upper gasket 232f, and rotatably connected with the grinding shell 211 through a lower bearing 232g and a lower gasket 232h, the transmission shaft 232d being capable of driving the movable grinding head 242 to rotate synchronously under the driving of the driven pulley 232b, so that the movable grinding head 242 is capable of rotating relative to the static grinding head 241 under the driving of the driving member 231. The driving member 231 and the movable grinding head 242 are distributed along the radial direction X of the coffee machine, which reasonably utilizes the internal space of the grinding shell 211 to place the driving member 231, and can reduce the size of the grinding assembly 2 in the axial direction Z of the coffee machine compared with the mode that the driving member 231 directly drives the movable grinding head 242, thereby improving the compactness of the structure of the coffee machine.

[0211] In addition, the grinding assembly 24 further comprises a spring 243 and an adjusting nut 244, the spring 243 being sleeved on the transmission shaft 232d, the two ends of the spring 243 along the axial direction Z of the coffee machine abutting against the grinding shell 211 and the movable grinding head 242 respectively, the end of the transmission shaft 232d away from the grinding shell 211 along the axial direction Z of the coffee machine penetrating through the movable grinding head 242 and being threadedly connected with the adjusting nut 244. The adjusting nut 244 and the spring 243 are used for jointly limiting the movement of the movable grinding head 242 along the axial direction Z of the coffee machine, so as to improve the stability of the movable grinding head 242. The static grinding head 241 has a grinding portion 241a, and the movable grinding head 242 has a grinding matching portion 242a, at least one of the grinding portion 241a and the grinding matching portion 242a being a bevel, the adjusting nut 244 being used for moving relative to the transmission shaft 232d along the axial direction Z of the coffee machine, so that the movable grinding head 242 is capable of moving relative to the static grinding head 241 along the axial direction Z of the coffee machine, thereby adjusting the distance between the grinding portion 241a and the grinding matching portion 242a in the radial direction of the movable grinding head 242, so as to change the fineness of the ground powder, thereby improving the use experience of the grinding assembly 2. When the distance between the grinding portion 241a and the grinding matching portion 242a is large, the ground powder is coarse; when the distance between the grinding portion 241a and the grinding matching portion 242a is small, the ground powder is fine. The spring 243 can ensure that the movable grinding head 242 is always balanced and stable during the above movement.

[0212] As Figure 14As shown, the first limiting plate 212 is provided with a limiting groove 212a, at least part of the driving member 231 is accommodated in the limiting groove 212a, the inner wall of the limiting groove 212a is provided with a limiting protrusion 212aa, the limiting protrusion 212aa abuts against the side wall of the driving member 231 along the radial direction X of the driving member 231, so as to improve the installation stability of the driving member 231. In combination with Figure 5 As shown, the first rotating shaft 101 is formed at the top of the brewing upper cover 311, i.e. the first limiting plate 212 is fixedly connected with the brewing upper cover 311, when the grinding assembly 2 rotates relative to the brewing assembly 3, the first limiting plate 212 is in a static state; when the brewing assembly 3 rotates relative to the grinding assembly 2, the first limiting plate 212 rotates synchronously with the brewing assembly 3, and the limiting protrusion 212aa can slide with the driving member 231 in the rotating process, i.e. the driving member 231 always remains in a static state.

[0213] Wherein, the driving member 231 can be a direct current motor, a stepping motor or other driving device, which is not limited in the embodiment. As shown in Figure 2 And Figure 5 As shown, the brewing assembly 3 has a second communication cavity 106 for communicating the brewing assembly 3 with the grinding assembly 2, the connecting wire between the power board 7 and the driving member 231 can pass through the first communication cavity 105 and the second communication cavity 106. Specifically, the second communication cavity 106 can be located at the first rotating shaft 101, the limiting groove 212a of the first limiting plate 212 is located at the second communication cavity 106, the control board 33 and the first limiting plate 212 are respectively provided with wire passing holes corresponding to the position of the first wire tube 342, one end of the connecting wire is connected with the power board 7, and the other end is sequentially connected with the driving member 231 through the first wire tube 342, the wire passing hole on the control board 33 and the wire passing hole on the first limiting plate 212. In addition, as shown in Figure 5 As shown, the grinding assembly 2 further comprises a switch button 25, the switch button 25 is connected with the power board 7 through a connecting wire, one end of the connecting wire is connected with the power board 7, and the other end is sequentially connected with the switch button 25 through the first wire tube 342, the wire passing hole on the control board 33 and the wire passing hole on the first limiting plate 212, and the gap between the driving member 231 and the limiting groove 212a. The first wire tube 342 is used to isolate the heat of the heating device 5, prevent the connecting wire from being damaged by high temperature, and also constrain the connecting wire to prevent the connecting wire from moving excessively, which is beneficial to shorten the length of the connecting wire and improve the stability of the connecting wire.

[0214] As shown in Figure 15As shown, in another embodiment, the main body 1 is provided with a mounting column 11 extending along the axial direction Z of the coffee machine, the mounting column 11 passes through the brewing body 31 and is fixedly connected with the grinding body 21, that is, the grinding body 21 and the main body 1 are relatively static structures, the grinding assembly 2 and the main body 1 cannot rotate relative to each other, which is conducive to improving the stability of the whole coffee machine. The brewing assembly 3 can rotate around the mounting column 11, when the brewing assembly 3 is rotated relative to the grinding body 21 and the main body 1 to Figure 15 the first state shown, the coffee machine is in a storage state, the main body 1 is used to limit the movement of the liquid receiving cup 32 along the axial direction Z of the coffee machine, and the brewing body 31 is used to limit the movement of the powder receiving cup 22 along the axial direction Z of the coffee machine. When the brewing assembly 3 is rotated relative to the grinding body 21 and the main body 1 to Figure 16 the second state shown, the liquid receiving cup 32 can be detached from the brewing body 31, and the powder receiving cup 22 can be detached from the grinding body 21, and the user can use the grinding function or the brewing function according to the needs.

[0216] As Figure 15 shown, one of the grinding shell 211 and the brewing upper cover 311 is provided with a first rotating shaft 101, and the other is provided with a first rotating connecting part 102 rotationally connected with the first rotating shaft 101, so that the brewing body 31 can rotate relative to the grinding body 21. One of the brewing shell 312 and the main body shell 12 is provided with a second rotating shaft 103, and the other is provided with a second rotating connecting part 104 rotationally connected with the second rotating shaft 103, so that the brewing body 31 can rotate relative to the main body 1. Since the main body 1 and the grinding assembly 2 are fixedly connected, they can jointly limit the movement of the brewing body 31 along the axial direction Z of the coffee machine, so in this embodiment, there is no need to provide the first limiting plate 212 and the second limiting plate 13, which is conducive to simplifying the structure of the coffee machine. In addition, the first rotating shaft 101 and the first rotating connecting part 102 can also be respectively provided with a first rotation stopping part 101a and a first rotation stopping cooperating part, and / or the second rotating shaft 103 and the second rotating connecting part 104 can also be respectively provided with a second rotation stopping part 103a and a second rotation stopping cooperating part, so as to realize the rotation limiting of the brewing assembly 3, which will not be described here.

[0217] As Figure 15As shown, in the present embodiment, the second rotating shaft 103 is formed on the top of the main body 1, and the mounting column 11 is in an integral structure with the second rotating shaft 103, so as to improve the structural strength and stability of the mounting column 11. The bottom of the grinding shell 211 is formed with a limiting groove for mounting the driving member 31, so as to realize the fixation of the driving member 31 and improve the stability of the driving member 31. The second wire pipe 541 can be arranged on the heating device fixing plate 54, and the connecting wires between the control panel 33 and the power panel 7, the connecting wires between the driving member 231 and the power panel 7, and the connecting wires between the switch button 25 and the power panel 7 can pass through the second wire pipe 541. In addition to the above-mentioned connecting and matching structure, the grinding assembly 2, the brewing assembly 3, and the remaining internal structure of the main body 1 can be consistent with the structures in the foregoing embodiments, and details are not described herein.

[0218] In the second embodiment, as shown in Figure 17 When the grinding assembly 2 is in the storage state, the main body 1 can limit the powder receiving cup 22 to move along the axial direction Z of the coffee machine, that is, the powder receiving cup 22 cannot be detached, thereby reducing the risk of losing the powder receiving cup 22; as shown in Figure 19 When the grinding assembly 2 is in the working state, the powder receiving cup 22 is completely misaligned with the main body 1 along the axial direction Z of the coffee machine, that is, the projection of the powder receiving cup 22 on the axial direction Z of the coffee machine is located outside the projection of the main body 1 on the axial direction Z of the coffee machine, the powder receiving cup 22 can be detached from the grinding body 21, the powder receiving cup 22 can move downward along the axial direction Z of the coffee machine without interfering with the main body 1, and 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). As shown in Figure 17 When the brewing assembly 3 is in the storage state, the grinding body 21 can limit the liquid receiving cup 32 to move along the axial direction Z of the coffee machine, that is, the liquid receiving cup 32 cannot be detached, thereby reducing the risk of losing the liquid receiving cup 32; as shown in Figure 19 When the brewing assembly 3 is in the working state, the grinding body 21 is completely misaligned with the liquid receiving cup 32 along the axial direction Z of the coffee machine, that is, the projection of the liquid receiving cup 32 on the axial direction Z of the coffee machine is located outside the projection of the grinding body 21 on the axial direction Z of the coffee machine, the liquid receiving cup 32 can be detached from the brewing body 31, and 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). When the brewing assembly 3 and the grinding assembly 2 are both in the working state by only rotating the grinding assembly 2, the second receiving space 108 is formed between the brewing body 31 and the main body 1, and the liquid receiving cup 32 can move downward along the axial direction Z of the coffee machine in the second receiving space 108 without interfering with the grinding body 21.

[0219] In a specific embodiment, as shown in Figure 20As shown, the brewing body 31 comprises a brewing shell 312, and the grinding body 21 comprises a grinding upper cover 213, one of the brewing shell 312 and the grinding upper cover 213 is provided with the first rotating shaft 101, and the other is provided with the first rotating connecting portion 102 which is in rotating connection with the first rotating shaft 101. The first rotating connecting portion 102 is a cylindrical structure extending along the axial direction Z of the coffee machine, the first rotating shaft 101 extends along the axial direction Z of the coffee machine, and at least part of the first rotating shaft 101 is located in the cylindrical structure. The first rotating shaft 101 can rotate relative to the first rotating connecting portion 102, and the first rotating connecting portion 102 can also rotate around the first rotating shaft 101, so that any one of the grinding assembly 2 and the brewing assembly 3 rotates relative to the other. The connection structure of the first rotating shaft 101 and the first rotating connecting portion 102 is relatively simple, and makes full use of the internal space of the grinding assembly 2 and the brewing assembly 3 without occupying additional space, which is conducive to reducing the volume of the coffee machine. In addition, when the first rotating connecting portion 102 is connected with the first rotating shaft 101, the brewing shell 312 can be lapped on the top wall of the grinding upper cover 213, so that the brewing assembly 3 is stably placed above the grinding assembly 2, which is conducive to improving the stability of the coffee machine.

[0220] In this embodiment, the brewing assembly 3 can rotate independently relative to the grinding assembly 2 and the main body 1, as shown in the figure. Figure 21 As shown, when the brewing assembly 3 is rotated to be completely misaligned with the grinding body 21 along the axial direction Z of the coffee machine, the liquid receiving cup 32 can be detached from the brewing body 31 to realize the brewing function of the coffee machine. The grinding assembly 2 and the brewing assembly 3 are independent of each other, and the user can directly rotate the grinding assembly 2 when using the grinding function of the coffee machine, and directly rotate the brewing assembly 3 when using the brewing function of the coffee machine, without affecting each other between the two functional assemblies. Moreover, by setting the brewing assembly 3 as a rotatable structure, when the brewing assembly 3 is completely misaligned with the main body 1 along the axial direction Z of the coffee machine, the height difference between the brewing assembly 3 and the table top is large enough, and other higher containers can be used to hold the brewed liquid, improving the applicability of the coffee machine.

[0221] As shown in the figure, Figure 20As shown, the grinding body 21 further comprises a grinding shell 211 connected with the grinding upper cover 213, and the main body 1 comprises a main body shell 12, one of the grinding shell 211 and the main body shell 12 is provided with the second rotating shaft 103, and the other is provided with the second rotating connection part 104 rotationally connected with the second rotating shaft 103, the second rotating connection part 104 is a cylindrical structure extending along the axial direction Z of the coffee machine, the second rotating shaft 103 extends along the axial direction Z of the coffee machine, and at least part of the second rotating shaft 103 is located in the cylindrical structure, and the second rotating shaft 103 can rotationally cooperate with the second rotating connection part 104, so that the grinding body 21 can rotate relative to the main body 1. Similarly, the connection structure of the second rotating shaft 103 and the second rotating connection part 104 is relatively simple, which is beneficial to reduce the volume of the coffee machine and improve the stability of the coffee machine.

[0222] Further, as shown in the drawings, Figure 20 The grinding body 21 further comprises a first limiting plate 212 fixedly connected with the first rotating shaft 101, and at least part of the first rotating connection part 102 is clamped between the first limiting plate 212 and the first rotating shaft 101 along the axial direction Z of the coffee machine, so as to limit the movement of the brewing assembly 3 relative to the grinding assembly 2 along the axial direction Z of the coffee machine, thereby improving the stability of the rotational connection between the grinding assembly 2 and the brewing assembly 3. And / or, the main body 1 further comprises a second limiting plate 13 fixedly connected with the second rotating shaft 103, and at least part of the second rotating connection part 104 is clamped between the second limiting plate 13 and the second rotating shaft 103 along the axial direction Z of the coffee machine, so as to limit the movement of the grinding assembly 2 relative to the main body 1 along the axial direction Z of the coffee machine, thereby improving the stability of the rotational connection between the main body 1 and the grinding assembly 2. Therefore, when the first limiting plate 212 and the second limiting plate 13 are provided at the same time, the stability of the overall structure of the coffee machine can be improved.

[0223] Among them, the first limiting plate 212 and the first rotating shaft 101, the second limiting plate 13 and the second rotating shaft 103 can be fixedly connected by bolts or other fasteners, which are not limited in the embodiment.

As shown in the drawings, Figure 22As shown, the first rotating connecting part 102 can have a first rotating fitting groove 102a, and the first rotation-stopping fitting part is arranged in the first rotating fitting groove 102a. During the relative rotation between the grinding assembly 2 and the brewing assembly 3, the first rotation-stopping part 101a and the first rotating fitting groove 102a are in sliding fit. When the first rotation-stopping part 101a and the first rotation-stopping fitting part abut, the relative rotation between the grinding assembly 2 and the brewing assembly 3 is stopped. Alternatively, the first rotating shaft 101 can have the first rotating fitting groove 102a, and the first rotation-stopping part 101a is located in the first rotating fitting groove 102a, and the first rotation-stopping fitting part and the first rotating fitting groove 102a are in sliding fit.

The second rotation-stopping fitting part is used to abut and fit with the second rotation-stopping part 103a during the relative rotation between the second rotating shaft 103 and the second rotating connecting part 104, so as to limit the rotation of the grinding assembly 2 relative to the main body 1. The grinding assembly 2 and the main body 1 can be kept in a stable state at a specific relative position. Similarly, as shown, the second rotating connecting part 104 can have a second rotating fitting groove 104a, and the second rotation-stopping fitting part is arranged in the second rotating fitting groove 104a. During the rotation of the grinding assembly 2 relative to the main body 1, the second rotation-stopping part 103a and the second rotating fitting groove 104a are in sliding fit. When the second rotation-stopping part 103a and the second rotation-stopping fitting part abut, the rotation of the grinding assembly 2 is stopped. Alternatively, the second rotating shaft 103 can have the second rotating fitting groove 104a, and the second rotation-stopping part 103a is located in the second rotating fitting groove 104a, and the second rotation-stopping fitting part and the second rotating fitting groove 104a are in sliding fit. When the first rotation-stopping part 101a and the first rotation-stopping fitting part, and the second rotation-stopping part 103a and the second rotation-stopping fitting part are provided at the same time, the stability of the coffee machine as a whole in the working state can be improved. Figure 23 Figure 23 Wherein, for the grinding assembly 2, by adjusting the relative position of the second rotation-stopping part 103a and the second rotation-stopping fitting part in the circumferential direction of the second rotating shaft 103, the one-way rotation or the two-way rotation of the grinding assembly 2 can be realized. For example, as shown in FIG. 8(a), the grinding assembly 2 can rotate in the clockwise direction from the initial position, and can also rotate in the counterclockwise direction. The maximum angle a1 of the clockwise rotation and the maximum angle a2 of the counterclockwise rotation can be equal or not equal, but both should not be greater than 300°. For another example, as shown in FIG. 8(b), the grinding assembly 2 can rotate in the counterclockwise direction or the clockwise direction from the initial position in a one-way manner, but the maximum angle β of the rotation should not exceed 360°.

[0226] Wherein, for the grinding assembly 2, by adjusting the relative position of the second rotation-stopping part 103a and the second rotation-stopping fitting part in the circumferential direction of the second rotating shaft 103, the one-way rotation or the two-way rotation of the grinding assembly 2 can be realized. For example, as shown in FIG. 8(a), the grinding assembly 2 can rotate in the clockwise direction from the initial position, and can also rotate in the counterclockwise direction. The maximum angle a1 of the clockwise rotation and the maximum angle a2 of the counterclockwise rotation can be equal or not equal, but both should not be greater than 300°. For another example, as shown in FIG. 8(b), the grinding assembly 2 can rotate in the counterclockwise direction or the clockwise direction from the initial position in a one-way manner, but the maximum angle β of the rotation should not exceed 360°.

[0227] ​Similarly, by adjusting the relative positions of the first anti-rotation part 101a and the first anti-rotation mating part in the circumferential direction of the first rotating shaft 101, the brewing component 3 can be made to rotate unidirectionally or bidirectionally relative to the grinding component 2, which will not be elaborated here. Of course, the relative positional relationship between the first anti-rotation part 101a and the first anti-rotation mating part in the circumferential direction of the first rotating shaft 101 can also limit the rotation effect of the grinding component 2.

[0228] In this embodiment, such as Figure 24 As shown, the main body casing 12 includes a first part 121 and a second part 122 distributed radially X along the coffee machine. A water tank 4 and a heating device 5 are also disposed inside the main body casing 12. The water tank 4 is installed in the first part 121, and the heating device 5 is installed in the second part 122. The water tank 4 has an open structure, including a tank body 41 and a water tank cover 43. The tank body 41 is used to store liquid, and a water outlet 411 is provided at the bottom, allowing the user to add liquid from the top of the tank body 41. The water tank cover 43 is fastened to the tank body 41. The heating device 5 includes a water inlet 51 and a water outlet 52. The water outlet 52 is used to communicate with the water pipe 313 inside the brewing body 31, combined with… Figure 20 and Figure 21 As shown, the coffee machine also includes a water pump 6, which is connected to both the inlet 51 and the outlet 411. The water pump 6 draws liquid from the water tank 4 and sends it to the heating device 5 for heating. It also increases the pressure of the liquid within the heating device 5, ensuring smooth flow from the inlet 51 to the outlet 52, thereby accelerating the liquid flow and improving the coffee machine's heating efficiency. The heated liquid flows to the water pipe 313 to realize the coffee machine's brewing function. A coffee machine with a heating device 5 can be used even without hot water, making it more convenient and practical, and improving the user experience. Along the Z-axis of the coffee machine, the outlet 52 is located above the inlet 51, meaning the heating device 5 uses a bottom-in, top-out configuration. This helps to expel air from the heating device 5, improving heating efficiency. Furthermore, the bottom-in, top-out configuration allows the liquid to remain in the heating device 5 for a longer time, resulting in more thorough heating.

[0229] like Figure 24 As shown, the main body shell 12 is also equipped with a heating device insulation component and a heating device fixing plate 54, combined with Figure 20As shown, the top of the heating device heat insulation piece 53 is fixedly connected with the second part 122, and the bottom of the heating device heat insulation piece 53 is fixedly connected with the heating device fixed plate 54. The heating device heat insulation piece 53 and the heating device fixed plate 54 enclose a containing space, and the heating device 5 is installed in the containing space. On the one hand, the heating device heat insulation piece 53 is sleeved on the outer periphery of the heating device 5, which can reduce heat loss of the heating device 5 and also reduce the influence of high temperature of the heating device 5 on other electrical devices and pipelines in the main body 1. On the other hand, the heating device heat insulation piece 53 and the heating device fixed plate 54 can jointly limit the movement of the heating device 5 in the axial direction Z of the coffee machine, so as to realize stable installation of the heating device 5. Specifically, the heating device 5 has a cylindrical structure, the heating device fixed plate 54 is provided with a corresponding annular groove 542, and the bottom of the heating device 5 is installed in the annular groove 542, so as to limit the movement or deviation of the heating device 5 along the radial direction X thereof, thereby further improving the installation stability of the heating device 5. Of course, the bottom of the heating device 5 can also be fixedly connected with the annular groove 542 by using bolts or other fasteners, which is not limited in the embodiment.

[0230] As shown in Figure 24 The main body 1 further comprises a main body bottom cover 14 fixedly connected with the main body shell 12, and the power supply box 71 can enclose a containing space with the main body bottom cover 14, so as to install the power supply panel 7 in the containing space.

[0231] As shown in Figure 10 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 conducive to saving the internal space of the main body 1. Moreover, the heating film 42 is electrically connected with the battery 8, so that it can be used in the case of weak electricity, which is more convenient for users to use the coffee machine when going out.

[0232] In the embodiment, when the brewing assembly 3 is heated by external power supply (i.e. in the case of 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 being heated. When the brewing assembly 3 is heated by the battery 8 (i.e. in the case of 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.

[0233] As shown in Figure 25As shown, the brewing assembly 3 further comprises a control panel 33 and a control panel heat insulation piece 34, the brewing upper cover 311 and the brewing shell 312 are fixedly connected along the axial direction Z of the coffee machine, the control panel 33 and the control panel heat insulation piece 34 can be clamped and fixed by the brewing upper cover 311 and the brewing shell 312, and the control panel heat insulation piece 34 is used for heat insulation to prevent the internal high-temperature environment of the coffee machine from affecting the normal work of the control panel 33. Specifically, the outer side wall of the control panel heat insulation piece 34 can be provided with several positioning portions 343 at intervals, which are used to cooperate with the structure on the inner wall of the brewing shell 312 to improve the installation stability of the control panel heat insulation piece 34 and prevent it from shaking. The power panel 7 is electrically or signal connected with the control panel 33 and supplies power for the control panel 33, the brewing upper cover 311 is provided with a control panel 311a, the control panel 33 can be electrically or signal connected with the control panel 311a and the internal electrical devices (such as the heating device 5, the water pump 6, etc.) of the coffee machine, after the user touches the operation panel 311a, the control panel 33 can receive the corresponding signal and control the corresponding electrical devices to open or close according to the corresponding signal, so as to realize different functions of the coffee machine.

[0234] For example, the water tank 4 further comprises a thermistor 44, which 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 panel 33, when the user selects the brewing function by operating the control panel 311a, the control panel 33 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 panel 33 can control the heating film 42 to be turned off and the water pump 6 to be turned on when the liquid reaches the preset temperature, so as to deliver the heated liquid to the water pipe 313 to complete the brewing.

[0235] As shown in Figure 19 The main body 1 has a first communication cavity 105 for communicating the grinding assembly 2 with the main body 1, and the grinding assembly 2 has a second communication cavity 106 for communicating the grinding assembly 2 with the brewing assembly 3. Figure 21 As shown, the control panel heat insulation piece 34 is located directly above the second communication cavity 106, and the control panel heat insulation piece 34 is provided with a notch portion 341. Figure 21 The arrow direction in the figure is the flow direction of the liquid, the heating device 5 is connected with the water pipe 313 through a connecting water pipe, one end of the connecting water pipe is communicated with the water outlet 411 of the heating device 5, and the other end is communicated with the water pipe 313 through the first communication cavity 105, the second communication cavity 106 and the notch portion 341. The notch portion 341 not only serves to avoid the connecting pipeline and provide space for the connecting pipeline, but also can constrain the connecting pipeline to prevent it from moving excessively, which is conducive to shortening the length of the connecting pipeline and improving the stability of the connecting pipeline.

[0236] In the embodiment, the second rotating shaft 103 is formed on the top of the main body shell 12, the first communication cavity 105 is located in the second rotating shaft 103, and the heating device fixing plate 54 is provided with a second wire pipe 541 extending along the axial direction Z of the coffee machine and located in the hollow structure of the heating device 5. The first rotating shaft 101 is formed on the grinding upper cover 213, the second communication cavity 106 is located in the first rotating shaft 101, the control panel heat insulation piece 34 is located directly above the second communication cavity 106, and the first wire pipe 342 is provided and extends into the second communication cavity 106 along the axial direction Z of the coffee machine. The connecting wires between the power board 7 and the control panel 33 pass through the first wire pipe 342 and the second wire pipe 541, the second wire pipe 541 is used to isolate the heat of the heating device 5 to prevent the connecting wires from being damaged by high temperature, and the first wire pipe 342 and the second wire pipe 541 can constrain the connecting wires to prevent the connecting wires from moving excessively, which is beneficial to shorten the length of the connecting wires and improve the stability of the connecting wires.

[0237] In another embodiment, as shown in Figure 26 , the heating device 5 is installed on the outer side wall of the box body 41 or the inner side wall of the box body 41, the water outlet 411 is in communication with the water inlet end 51 of the heating device 5, and the water pipe 313 is in communication with the water outlet end 52 of the heating device 5, that is, the heating device 5 and the water tank 4 can be integrated together, so that the structure of the heating device 5 and the water tank 4 is more compact, so as to save the space inside the main body 1. In the embodiment, the heating device heat insulation piece 53 is sleeved on the outer side wall of the integrated structure and the top thereof is fixedly connected with the main body shell 12, and the heating device fixing plate 54 is not required. When the integrated structure of the heating device 5 and the water tank 4 is installed in the first part 121, the second part 122 has more space in the axial direction Z of the coffee machine for installing electrical devices such as the power board 7, the battery 8, and the water pump 6, which is beneficial to further shorten the length of the connecting pipeline and the connecting wires. In addition, in the embodiment, the water pump 6 can be used to communicate the water outlet 411 with the water inlet end 51 or to communicate the water outlet end 52 with the water pipe 313, which can both play a role in conveying the heated liquid to the water pipe 313.

[0238] As shown in Figure 25 , the brewing body 31 includes a body part 301 and a brewing part 302 which are detachably connected, the body part 301 includes a brewing upper cover 311, a brewing shell 312, a water pipe 313, a control panel 33, and a control panel heat insulation piece 34, and the brewing part 302 is used to accommodate food material powder to be brewed. As shown in Figure 12As shown, when the brewing assembly 3 is in the storage state, the liquid receiving cup 32 is connected to the body part 301, and the brewing part 302 is contained in the liquid receiving cup 32. When the liquid receiving cup 32 is detached from the body part 301, the brewing part 302 can also be detached from the body part 301, facilitating the user to fill the food material powder into the brewing part 302 or pour the food material powder out, and facilitating the cleaning of the brewing part 302. The brewing part 302 can be threadedly connected with the brewing shell 312 or buckled, which is not limited in the embodiment.

[0239] As shown, Figure 13 The brewing part 302 includes a detachably connected upper cover 302a and a lower cover 302b. The upper cover 302a is provided with a through hole in communication with the water passage pipe 313. The lower cover 302b is provided with a water outlet nozzle in communication with the outside. The brewed liquid flows out of the water outlet nozzle. The upper cover 302a and the water passage pipe 313 are sealingly connected through a first sealing ring 302c, a sealing ring gasket 302d, a second sealing ring 302e, a sealing gasket 302f and a sealing gasket pressing plate 302g. The lower cover 302b is provided with a food material bowl 302i. The food material bowl 302i is stably connected with the lower cover 302b through a limiting snap spring 302j. The food material powder to be brewed is placed in the food material bowl 302i. A filter screen 302m is fixedly installed between the food material bowl 302i and the water outlet nozzle through a filter screen pressing plate 302k. The filter screen 302m is used for filtering the food material powder. A water distribution screen plate 302h can also be arranged between the sealing gasket pressing plate 302g and the food material bowl 302i, so that the liquid in the water passage pipe 313 can uniformly flow to the food material bowl 302i, improving the uniformity of brewing.

[0240] In a specific embodiment, as shown, Figure 27 The grinding body 21 further includes a grinding upper cover 213 fixedly connected with the top of the grinding shell 211. The grinding upper cover 213 is formed with a material box 213a for containing the food material to be ground. The bottom of the material box 213a is in communication with the grinding shell 211. A material box cover 215 is detachably connected with the top of the material box 213a. The user can add the food material to be ground to the material box 213a after opening the material box cover 215, which is more convenient to use. 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 with 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 material 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.

[0241] Specifically, in combination withFigure 19 As shown, the driving device 23 comprises a driving member 231 and a transmission assembly 232, the transmission assembly 232 comprising a transmission shaft 232d, a driving pulley 232a, a driven pulley 232b and a synchronous belt 232c wound around the driving pulley 232a and the driven pulley 232b, the driving pulley 232a being sleeved on a driving shaft of the driving member 231, the driven pulley 232b being connected with the movable grinding head 242 through the transmission shaft 232d, the transmission shaft 232d being rotatably connected with the grinding upper cover 213 through an upper bearing 232e and an upper gasket 232f, and rotatably connected with the grinding shell 211 through a lower bearing 232g and a lower gasket 232h, the transmission shaft 232d being capable of driving the movable grinding head 242 to rotate synchronously under the driving of the driven pulley 232b, so that the movable grinding head 242 is capable of rotating relative to the static grinding head 241 under the driving of the driving member 231. The driving member 231 and the movable grinding head 242 are distributed along the radial direction X of the coffee machine, which reasonably utilizes the internal space of the grinding shell 211 to place the driving member 231, and can reduce the size of the grinding assembly 2 in the axial direction Z of the coffee machine compared with the mode that the driving member 231 directly drives the movable grinding head 242, thereby improving the compactness of the structure of the coffee machine.

[0242] In addition, the grinding assembly 24 further comprises a spring 243 and an adjusting nut 244, the spring 243 being sleeved on the transmission shaft 232d, the two ends of the spring 243 along the axial direction Z of the coffee machine abutting against the grinding shell 211 and the movable grinding head 242 respectively, the end of the transmission shaft 232d away from the grinding shell 211 along the axial direction Z of the coffee machine penetrating through the movable grinding head 242 and being threadedly connected with the adjusting nut 244. The adjusting nut 244 and the spring 243 are used for jointly limiting the movement of the movable grinding head 242 along the axial direction Z of the coffee machine, so as to improve the stability of the movable grinding head 242. The static grinding head 241 has a grinding portion 241a, and the movable grinding head 242 has a grinding matching portion 242a, at least one of the grinding portion 241a and the grinding matching portion 242a being a bevel, the adjusting nut 244 being used for moving relative to the transmission shaft 232d along the axial direction Z of the coffee machine, so that the movable grinding head 242 is capable of moving relative to the static grinding head 241 along the axial direction Z of the coffee machine, thereby adjusting the distance between the grinding portion 241a and the grinding matching portion 242a in the radial direction of the movable grinding head 242, so as to change the fineness of the ground powder, thereby improving the use experience of the grinding assembly 2. When the distance between the grinding portion 241a and the grinding matching portion 242a is large, the ground powder is coarse; when the distance between the grinding portion 241a and the grinding matching portion 242a is small, the ground powder is fine. The spring 243 can ensure that the movable grinding head 242 is always balanced and stable during the above movement.

[0243] As Figure 27As shown, the grinding body 21 further comprises a fixing frame 214 fixedly connected with the grinding shell 211, and the driving member 231 is fixedly installed on the fixing frame 214 to ensure that the driving member 231 can keep relatively static with the grinding shell 211 during the rotation of the grinding assembly 2 to achieve a stable state. The driving member 231 can be a direct current motor, a stepping motor or other driving device, and the present embodiment does not limit this.

[0244] The grinding assembly 2 further comprises a switch button 25, and the connecting wires between the switch button 25 and the power board 7 and the connecting wires between the driving member 231 and the power board 7 can pass through the second wire passing pipe 541 and the first communication cavity 105. The second wire passing pipe 541 is used to isolate the heat of the heating device 5 to prevent the connecting wires from being damaged by high temperature, and can also constrain the connecting wires to prevent the connecting wires from moving excessively, which is beneficial to shorten the length of the connecting wires and improve the stability of the connecting wires.

[0245] For the coffee machine provided in the present embodiment, in another embodiment, the main body 1 is provided with a mounting column 11 extending along the axial direction Z of the coffee machine, and the mounting column 11 is fixedly connected with the grinding body 21 and the brewing body 31, i.e., the brewing body 31 and the main body 1 are relatively static structures, and the brewing assembly 3 and the main body 1 cannot rotate relative to each other, which is beneficial to improve the stability of the whole coffee machine. The grinding assembly 2 can rotate around the mounting column 11, and when the grinding assembly 2 rotates relative to the brewing body 31 and the main body 1 to a first state, the main body 1 is used to limit the powder receiving cup 22 from moving along the axial direction Z of the coffee machine, and the grinding body 21 is used to limit the liquid receiving cup 32 from moving along the axial direction Z of the coffee machine. When the grinding assembly 2 rotates relative to the brewing body 31 and the main body 1 to a second state, the powder receiving cup 22 can be detached from the grinding body 21, and the liquid receiving cup 32 can be detached from the brewing body 31, at this time, the user can use the grinding function or the brewing function according to the needs. In addition, in the present embodiment, the grinding assembly 2, the brewing assembly 3 and the remaining internal structure of the main body 1 can be consistent with the structures in the foregoing embodiments, which will not be described here.
