Technical Field

[0001] The present application relates to the field of household appliances, and in particular to a coffee machine. Background Art

[0002] In order to meet the needs of users, some existing portable coffee machines are equipped with a grinding assembly, which can be used to grind coffee beans, thereby improving the practicality of the coffee machine. However, the coffee machine with a grinding assembly is usually large in size, which is inconvenient to move or carry out. Summary of the invention

[0003] The present application provides a coffee machine, which can solve the problem that the coffee machine in the prior art is too large and inconvenient to carry.

[0004] The present application provides a coffee machine, comprising: a main body, comprising a base and a connecting portion arranged on the top of the base, the connecting portion comprising a first connecting groove and a second connecting groove, and along the axial direction of the coffee machine, the first connecting groove is located above the second connecting groove; a grinding component, slidably connected to one of the first connecting groove and the second connecting groove, and the grinding component can slide relative to the main body to a storage state or a grinding state; a brewing component, slidably connected to the other of the first connecting groove and the second connecting groove, and the brewing component can slide relative to the main body to a storage state or a brewing state.

[0005] In the above scheme, the main body, the grinding assembly and the brewing assembly are arranged along the axial direction of the coffee machine, which can reduce the size of the coffee machine in its length direction and / or width direction, making the overall structure of the coffee machine more compact, which is conducive to the miniaturization of the coffee machine. Moreover, the grinding assembly and the brewing assembly are respectively connected to the main body in a sliding manner, which can improve the space utilization rate and space widening capacity of the coffee machine, so that the volume of the coffee machine in the storage state is minimized, saving storage space, and facilitating users to store and carry out. For coffee machine products, it can also reduce the packaging size and packaging cost. Moreover, the grinding assembly and the brewing assembly are respectively connected to one of the first connecting groove and the second connecting groove in a sliding manner, so that the grinding assembly and the brewing assembly can be used independently of each other. When the user needs to use the grinding function of the coffee machine, the grinding assembly can be directly slid to the grinding state, and when the user needs to use the brewing function of the coffee machine, the brewing assembly can be directly slid to the brewing state, which is more convenient to operate.

[0006] In a possible design, one of the grinding component and the first connecting groove is provided with a first limiting protrusion, and the other is provided with a first slide groove extending along the length direction of the coffee machine, and the first slide groove is slidably matched with the first limiting protrusion; one of the brewing component and the second connecting groove is provided with a second limiting protrusion, and the other is provided with a second slide groove extending along the length direction of the coffee machine, and the second slide groove is slidably matched with the second limiting protrusion; or, one of the grinding component and the second connecting groove is provided with a first limiting protrusion, and the other is provided with a first slide groove extending along the length direction of the coffee machine, and the first slide groove is slidably matched with the first limiting protrusion; one of the brewing component and the first connecting groove is provided with a second limiting protrusion, and the other is provided with a second slide groove extending along the length direction of the coffee machine, and the second slide groove is slidably matched with the second limiting protrusion.

[0009] In the above scheme, both ends of the accommodation space along the length direction of the coffee machine can be connected to the outside, so that the grinding assembly and the brewing assembly can slide outward along the length direction of the coffee machine. The accommodation space is divided into the first connecting groove and the second connecting groove only by the partition, and the structure is relatively simple and easy to manufacture. The partition can also cooperate with the top wall to limit the axial movement of the grinding assembly or the brewing assembly in the first connecting groove along the coffee machine and support the assembly; the partition can also cooperate with the top of the base to limit the axial movement of the brewing assembly or the grinding assembly in the second connecting groove, that is, the provision of the partition is conducive to improving the stability of the grinding assembly and the brewing assembly.

When the powder receiving cup is separated from the grinding body, it can be placed under the grinding body to hold the ground powder. The brewing body is used to hold the ingredient powder and brew the ingredient powder. When the liquid receiving cup is separated from the brewing body, it can be placed under the brewing body to hold the brewed liquid, thereby improving the functionality of the coffee machine. When the grinding assembly is in the storage state, the powder receiving cup cannot be disassembled, which can reduce the risk of losing the powder receiving cup; when the brewing assembly is in the storage state, the liquid receiving cup cannot be disassembled, which can reduce the risk of losing the liquid receiving cup.

[0145] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0146] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0147] like Figure 1As shown, the embodiment of the present application provides a coffee machine that can be used for daily home use or can be carried out for outdoor use. 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, and the connecting portion 12 includes a first connecting groove 121 and a second connecting groove 122. Along the axial direction Z 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 a storage 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 a storage state or a brewing state.

[0148] Specifically, in the first embodiment, the grinding assembly 2 can be slidably connected to the first connecting groove 121, and correspondingly, the brewing assembly 3 can be slidably connected to the second connecting groove 122. Figure 1 In the storage state shown in FIG. 1 , the projection of the grinding assembly 2 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 reducing 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 part of the projection of the grinding assembly 2 on the axial direction Z of the coffee machine is located outside the projection of the brewing assembly 3 on the axial direction Z of the coffee machine. At this time, there is a space below the grinding assembly 2 for placing a powder receiving container, and the grinding assembly 2 can perform grinding. Furthermore, the grinding assembly 2 includes a detachably connected grinding body 21 and a powder receiving cup 22. The grinding body 21 is used to grind coffee beans or other ingredients into powder. When the powder receiving cup 22 is separated from the grinding body 21, it can be placed under the grinding body 21 to hold the ground powder, thereby improving the functionality of the coffee machine. When the grinding assembly 2 slides relative to the first connecting groove 121 to Figure 1 In the storage state shown in FIG. 1 , the brewing assembly 2 can limit the movement of the powder receiving cup 22 along the axial direction Z of the coffee machine, that is, the powder receiving cup 22 cannot be disassembled, which can reduce the risk of losing the powder receiving cup 22; 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 and the brewing component 2 can be completely misaligned 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 brewing component 3 on the axial direction Z of the coffee machine, and the powder receiving cup 22 can move downward along the axial direction Z of the coffee machine without interfering with the brewing component 3, that is, the powder receiving cup 22 can be disassembled and separated 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 under the grinding body 21 to hold the ground powder (the user can also place other containers under the grinding body 21 to hold the ground powder).

[0149] Similarly, when the brewing component 3 slides relative to the second connecting groove 122 Figure 1 In the storage state shown in FIG. 1 , 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 reducing the storage volume of the coffee machine; when the brewing assembly 3 slides relative to the second connecting groove 122 to Figure 4 In the brewing state shown, at least part of the projection of the brewing component 3 on the axial direction Z of the coffee machine is located outside the projection of the base 11 on the axial direction Z of the coffee machine. At this time, there is a space below the brewing component 3 for placing a liquid receiving container, and the brewing component 3 can perform brewing. Furthermore, the brewing component 3 includes a brewing body 31 and a liquid receiving cup 32. The brewing body 31 is used to hold food powder and brew the food powder. When the liquid receiving cup 32 is separated from the brewing body 31, it can be placed below the brewing body 31 to hold the brewed liquid, thereby improving the functionality of the coffee machine. When the brewing component 3 slides relative to the second connecting groove 122 to Figure 1 In the storage state shown in FIG. 1 , the base 11 restricts the movement of the liquid receiving cup 32 along the axial direction Z of the coffee machine, that is, the liquid receiving cup 32 cannot be disassembled, which can reduce the risk of losing the liquid receiving cup 32; when the brewing component 3 slides relative to the second connecting groove 122 to Figure 4 In the brewing state shown, the liquid receiving cup 32 and the base 11 can be completely misaligned 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 base 11 on the axial direction Z of the coffee machine, and the liquid receiving cup 32 can move downward along the axial direction Z of the coffee machine without interfering with the base 11, that is, the liquid receiving cup 32 can be disassembled and separated 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 under the brewing body 31 to hold the brewed liquid (the user can also place other containers under the brewing body 31 to hold the brewed liquid).

[0150] Or, if Figure 5 and Figure 6As shown, in the second embodiment, the grinding assembly 2 can be slidably connected to the second connecting groove 122, and correspondingly, the brewing assembly 3 can be slidably connected to the first connecting groove 121. Figure 5 In the storage state shown in FIG. 1 , the base 11 can limit the movement of the powder cup 22 along the axial direction Z of the coffee machine, and the powder cup 22 cannot be disassembled, which can reduce the risk of losing the powder cup 22; when the grinding assembly 2 slides relative to the second connecting groove 122 to Figure 7 In the grinding state shown, the powder receiving cup 22 and the base 11 can be completely misaligned along the axial direction Z of the coffee machine, and the powder receiving cup 22 can be disassembled and separated from the grinding body 21 to realize the grinding function of the coffee machine. Figure 5 In the storage state shown in FIG. 1 , the grinding assembly 2 can limit the movement of the liquid receiving cup 32 along the axial direction Z of the coffee machine, and the liquid receiving cup 32 cannot be disassembled, which can reduce the risk of losing the liquid receiving cup 32; when the brewing assembly 3 slides relative to the first connecting groove 121 to Figure 8 In the brewing state shown, the liquid receiving cup 32 and the grinding assembly 2 can be completely displaced along the axial direction Z of the coffee machine, and the liquid receiving cup 32 can be disassembled and separated from the brewing body 31 to realize the brewing function of the coffee machine.

[0151] In summary, no matter it is the coffee machine structure of the first embodiment or the coffee machine structure of the second embodiment, when the grinding component 2 and the brewing component 3 are both in the storage state, the projection of the grinding component 2 on the axial direction Z of the coffee machine and the projection of the brewing component 3 on the axial direction Z of the coffee machine coincide with the projection of the base 11 on the axial direction Z of the coffee machine, so that the coffee machine is in a state of minimum overall volume. At this time, the coffee machine occupies less space, which is convenient for users to store it daily and carry it out.

[0152] Therefore, in the coffee machine provided by the embodiment 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, making the overall structure of the coffee machine more compact, which is conducive to the miniaturization of the coffee machine. Moreover, the grinding assembly 2 and the brewing assembly 3 are respectively connected to the main body 1 in a sliding manner, which can improve the space utilization rate and space widening capacity of the coffee machine, so that the volume of the coffee machine in the storage state is minimized, saving storage space, and facilitating users to store and carry out. For coffee machine products, it can also reduce the packaging size and packaging cost. Moreover, the grinding assembly 2 and the brewing assembly 3 are respectively connected to one of the first connecting groove 121 and the second connecting groove 122 in a sliding manner, 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 slide along the length direction X of the coffee machine relative to the main body 1, or can slide along the width direction Y of the coffee machine relative to the main body 1, and this embodiment does not limit this. Next, taking the grinding assembly 2 and the brewing assembly 3 can slide along the length direction X of the coffee machine relative to the main body 1 as an example, the specific structure of the coffee machine is introduced:

[0154] like Fig. 9 As shown, the connecting portion 12 includes a top wall 123, a first side wall 124 and a second side wall 125 which are arranged opposite to each other along the width direction Y of the coffee machine. The top wall 123, the first side wall 124, the second side wall 125 and the top of the main body 1 form a receiving space, and the two ends of the receiving space along the length direction X of the coffee machine can be connected to the outside, so that the grinding assembly 2 and the brewing assembly 3 can slide outward along the length direction X of the coffee machine. The connecting portion 12 also includes a partition 126 arranged in the receiving space, and the two ends of the partition 126 are respectively fixedly connected to the first side portion and the second side portion along the width direction Y of the coffee machine to separate 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. Moreover, by changing the position of the partition 126 in 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 the grinding assembly 2 and the brewing assembly 3 of different heights, thereby improving the versatility of the connecting portion 12. In addition, the partition 126 can also cooperate with the top wall 123 to limit the axial Z movement of the grinding component 2 or the brewing component 3 in the first connecting groove 121 along the coffee machine, and provide support for the component; the partition 126 can also cooperate with the top of the base 11 to limit the axial Z movement of the brewing component 3 or the grinding component 2 in the second connecting groove 122 of the coffee machine, that is, the provision of the partition 126 is beneficial to improving the stability of the grinding component 2 and the brewing component 3.

[0155] The grinding assembly 2 and the brewing assembly 3 may move in the same direction along the length direction X of the coffee machine, or may move in opposite directions along the length direction X of the coffee, which is not limited in this embodiment.

[0156] Combination Figure 2 and Fig. 9As shown, when the grinding assembly 2 is slidably connected 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 is slidably matched with the first limiting protrusion 101, and 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 it abuts against the end of the first sliding groove 102, so as to prevent the grinding assembly 2 from escaping from the first connecting groove 121. Among them, the inner walls on both sides 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 slide groove 104 extending along the length direction X of the coffee machine. The second slide groove 104 is slidably matched with the second limiting protrusion 103, and the second limiting protrusion 103 can guide the sliding process of the brewing component 3 to improve the sliding stability of the brewing component 3; the second limiting protrusion 103 can also limit the brewing component 3 from continuing to move along the length direction X of the coffee machine when it abuts against the end of the second slide groove 104, so as to prevent the brewing component 3 from escaping from the second connecting groove 122. Among them, the inner walls on both sides 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 slide groove 104 to further improve the sliding stability of the brewing component 3.

[0158] Similarly, combined Figure 6 and Fig.10As shown, when the grinding assembly 2 is slidably connected with the second connecting groove 122, one of the grinding body 21 and the second connecting groove 122 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 is slidably matched with the first limiting protrusion 101, and the first limiting protrusion 101 can guide and limit the grinding assembly 2 to improve the sliding stability of the grinding assembly 2 and prevent the grinding assembly 2 from escaping from the second connecting groove 122, and the inner walls on both sides 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 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 slide groove 104 is slidably matched with the second limiting protrusion 103, and the second limiting protrusion 103 can guide and limit the brewing component 3 to improve the sliding stability of the brewing component 3 and prevent the brewing component 3 from escaping from the first connecting groove 121, and the inner walls on both sides 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 slide groove 104.

[0159] like Figure 4 and Fig.11 As shown, the base 11 includes a base shell 1101 and a water tank 4, a water pump 6 and a heating device 5 installed in the base shell 1101. The water tank 4 is an open structure, including a box body 41 and a water tank cover 43. The box body 41 is used to store liquid, and a water outlet 411 is provided at the bottom. The user can add liquid into the box body 41 from the top. The water tank cover 43 is buckled on the box 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 is connected to the water inlet end 51 and the water outlet 411 respectively, and is used to suck the liquid in the water tank 4 and send it to the heating device 5 for heating. It is also used to increase the pressure of the liquid in the heating device 5 to ensure that the liquid can flow smoothly from the water inlet end 51 to the water outlet end 52, so as to speed up the flow speed of the liquid and improve 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 enhance the user experience.

[0160] Among them, along the axial direction Z of the coffee machine, the water outlet 52 is located above the water inlet 51, that is, the heating device 5 adopts a bottom-in-top-out method, which is conducive to exhausting the air of the heating device 5 and improving the heating efficiency. Moreover, the bottom-in-top-out method can make the liquid stay in the heating device 5 for a longer time and be heated more fully.

[0161] like Fig.11As shown, a power board 7 and a power box 71 are also provided in the base housing 1101. The power board 7 is used to convert the external input AC power into the DC power required by the internal electrical components, and is electrically connected to the internal electrical components (such as the heating device 5, the water pump 6, etc.) to power the electrical components. The base 11 also includes a base bottom cover 1102 fixedly connected to the base housing 1101. The power box 71 and the base bottom cover 1102 can form an installation space so that the power board 7 can be installed in the installation space. A battery 8 is also provided in the base housing 1101. The battery 8 is used to power the internal electrical components (such as the water pump 6) when there is no external power supply, so that the coffee machine is more convenient for users to carry 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 board 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 board 7, which is beneficial to saving the internal space of the base 11, and can also shorten the distance between the heating device 5 and the power board 7, which is beneficial to reducing the length of the connection line. Figure 4 As shown, the heating device 5 is 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. The bottom of the heating device 5 is installed in the annular groove, which can limit the movement or displacement of the heating device 5 along its radial direction X, further improving the installation stability of the heating device 5.

[0163] like Fig.12 As shown, the water tank 4 also includes a heating film 42, which covers the outer bottom wall of the box body 41 and is used to heat the liquid in the box body 41. The heating film 42 is relatively small in size, which is beneficial to saving the internal space of the base 11. The heating film 42 is electrically connected to the battery 8 and can be used in weak current conditions, which makes it more convenient for users to use the coffee machine when carrying it out, thereby expanding the use scenarios of the coffee machine.

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

[0165] like Fig.13As shown, the brewing body 31 includes a brewing shell 311, a brewing cover 312 connected to the brewing shell 311, and a control board 314 installed inside the brewing shell 311. The control board 314 is electrically connected or signal-connected to the power board 7 and supplies power to the control board 314. The brewing cover 312 is provided with a control panel 312b. The control board 314 can be electrically connected or signal-connected to the control panel 312b and the internal electrical components of the coffee machine (such as the heating device 5, the water pump 6, etc.). After the user touches the operation panel 312b, the control board 314 can receive the corresponding signal and control the corresponding electrical components to turn on or off according to the corresponding signal, thereby realizing different functions of the coffee machine.

[0166] For example, Fig.11 As shown, the water tank 4 also includes 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 respectively electrically connected or signal-connected to 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 box body 41, and monitor the temperature of the liquid in the box body 41 through the thermistor 44, so that the control board 314 turns off the heating film 42 and turns on the water pump 6 when the liquid reaches a preset temperature, thereby transporting the heated liquid to the water pipe 313 to complete the brewing.

[0167] Combination Figure 4 and Fig. 9 As shown, 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 used to connect the water outlet end 52 and the water pipe 313 is connected to the water outlet end 52, and the other end passes through the first through hole 111 and the second through hole 311a in sequence and then communicates with the water pipe 313. When the brewing component 3 is slidably connected to the second connecting groove 122, the distance between the heating device 5 and the water pipe 313 can be shortened, thereby shortening the water flow path, which is conducive to shortening the length of the connecting water pipe. Accordingly, a water pump 6 with lower power can be used to achieve energy saving. In addition, the control board 314 is electrically connected to the power board 7 through the first connecting wire. One end of the first connecting wire is connected to the power board 7, and the other end passes through the first through hole 111 and the second through hole 311a in sequence and then connects to the control board 314.

[0168] The first through hole 111 is relatively small in size, and can play a role in restraining and limiting the connection water pipe and the first connection wire; the second through hole 311a extends along the length direction X of the coffee machine, which can reduce the wear of the connection water pipe and the first connection wire caused by the brewing component 3 during the sliding process, which is conducive to extending the service life of the connection water pipe and the first connection wire. The number of the first through hole 111 can be one, and the connection water pipe and the first connection wire pass through the same first through hole 111, or Fig. 9 As shown, the number of the first through holes 111 may be two, and the connecting water pipe and the first connecting wire pass through one of the first through holes 111 respectively.

[0169] The grinding body 21 includes a grinding cover 212 and a grinding shell 211 connected to each other. Figure 6 and Figure 8 As shown, when the brewing body 31 is slidably connected to 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 indicates the flow path of the liquid. One end of the connecting water pipe used to connect the water outlet 52 and the water pipe 313 is connected to the water outlet 52, and the other end passes through the first through hole 111, the fourth through hole 211a, the third through hole 212a and the second through hole 311a in sequence and then communicates with the water pipe 313. One end of the first connecting wire used to connect the control board 314 and the power board 7 is connected to the power board 7, and the other end passes through the first through hole 111, the fourth through hole 211a, the third through hole 212a and the second through hole 311a in sequence and then connects to the control board 314. 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 Figure 6 As shown, the number of the third through holes 212a may be two, and the connecting water pipe and the first connecting wire pass through one of the third through holes 212a respectively.

[0170] Similarly, the first through hole 111 and the third through hole 212a can constrain and limit 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, which can reduce the wear of the connecting water pipe and the first connecting wire caused by the brewing component 3 and the grinding component 2 during the sliding process, which is beneficial to extend the service life of the connecting water pipe and the first connecting wire.

[0171] In addition, if Fig.10 As shown, when the brewing body 31 is slidably connected to the first connecting groove 121, one or two notches 126a may be provided on the partition 126 to avoid the connecting water pipe and the first connecting wire, and also to play a certain restraining role on the connecting water pipe and the first connecting wire.

[0172] like Fig.13 As shown, the brewing body 31 includes a detachably connected main body 3101 and a brewing part 3102, the main body 3101 includes a brewing upper cover 312, a brewing shell 311, a water pipe 313 and a control panel 314, and the brewing part 3102 is used to accommodate the food powder to be brewed. When the brewing component 3 is in the storage state, the liquid receiving cup 32 is connected to the main body 3101, and the brewing part 3102 is accommodated in the liquid receiving cup 32. When the brewing component 3 is rotated until the liquid receiving cup 32 and the base 11 are completely misaligned along the axial direction Z of the coffee machine, after the liquid receiving cup 32 is disassembled from the main body 3101, the brewing part 3102 can also be disassembled and separated from the main body 3101, which is convenient for users to fill the food powder into the brewing part 3102, or pour out the food powder, and it is also convenient to clean the brewing part 3102. The brewing portion 3102 may be threadedly connected to the brewing shell 311 or snap-connected, which is not limited in this embodiment.

[0173] like Fig.14 As shown, the brewing part 3102 includes an upper cover 3102a and a lower cover 3102b which are detachably connected. The top of the upper cover 3102a is provided with a through hole connected to the water pipe 313, and the lower cover 3102b is provided with a water outlet connected to the outside, and the brewed liquid flows out through the water outlet. Among them, a sealed connection is formed between the upper cover 3102a and the water pipe 313 through the first sealing ring 3102c, the sealing ring gasket 3102d, the second sealing ring 3102e, the sealing pad 3102f and the sealing pad pressing plate 3102g; a powder bowl 3102i is arranged in the lower cover 3102b, and the powder bowl 3102i is stably connected to the lower cover 3102b through a limiting clamp spring 3102j, and the food 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 through a filter screen pressing plate 3102k, and the filter screen 3102m is used to filter the food powder; a water dividing mesh plate 3102h can also be arranged between the sealing pad pressing plate 3102g and the powder bowl 3102i, so that the liquid in the water pipe 313 can flow evenly to the powder bowl 3102i, thereby improving the uniformity of brewing.

[0174] like Fig.15As shown, a material box 212b is formed on the grinding upper cover 212, and the material box 212b is used to hold the food to be ground. The bottom of the material box 212b is connected to the grinding shell 211, and a material box cover 213 is arranged on the top of the material box 212b and is snap-fitted with it. After the user opens the material box cover 213, he can add the food to be ground to the material box 212b, which is more convenient to use. A driving device 23 and a grinding assembly 24 are installed in the grinding shell 211. 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 drive of the driving device 23, so as to grind the food together with the static grinding head 241, and the ground food powder can fall to the outside through the gap between the static grinding head 241 and the dynamic grinding head 242.

[0175] Specifically, combined 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 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 movable grinding head 242 through the transmission shaft 232d, the transmission shaft 232d is rotatably connected to the grinding upper cover 212 through the upper bearing 232e and the upper gasket 232f, and is rotatably connected to the grinding shell 211 through the lower bearing 232g and the lower gasket 232h, the transmission shaft 232d can drive the movable grinding head 242 to rotate synchronously under the drive of the driven pulley 232b, so that the movable grinding head 242 can rotate relative to the static grinding head 241 under the drive of the driving member 231. The driving member 231 and the moving grinding head 242 are distributed along the length direction X of the coffee machine, and the driving member 231 is placed in the inner space of the grinding shell 211 in a reasonable manner. Compared with the method in which the driving member 231 directly drives the moving 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 coffee machine structure is improved. The driving member 231 can be a DC motor, a stepping motor or other driving device, which is not limited in this embodiment.

[0176] In addition, the grinding assembly 24 further includes a spring 243 and an adjusting nut 244. The spring 243 is sleeved on the transmission shaft 232d. The two ends of the spring 243 along the axial direction Z of the coffee machine are respectively in contact with the grinding shell 211 and the movable grinding head 242. Along the axial direction Z of the coffee machine, one end of the transmission shaft 232d away from the grinding shell 211 passes through the movable grinding head 242 and is threadedly connected with the adjusting nut 244. The adjusting nut 244 and the spring 243 are used to jointly limit the movement of the movable grinding head 242 along the axial direction Z of the coffee machine to improve the stability of the movable grinding head 242. The static grinding head 241 has a grinding portion 241a, and the dynamic grinding head 242 has a grinding matching portion 242a. At least one of the grinding portion 241a and the grinding matching portion 242a is an inclined surface. The adjusting nut 244 is used to move relative to the transmission shaft 232d along the axial direction Z of the coffee machine, so that the dynamic grinding head 242 can move relative to the static grinding head 241 in 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 dynamic grinding head 242, thereby changing the coarseness of the ground powder, and improving the user experience of the grinding assembly 3. When the distance between the grinding portion 241a and the grinding matching portion 242a is large, the ground powder is coarser; when the distance between the grinding portion 241a and the grinding matching portion 242a is small, the ground powder is finer.
