With these features, the brewing container 20 and housing 11 can be connected to form a single unit, making this device a small, portable coffee machine.

[0040] Please see Figure 1-9 In one embodiment of this utility model, the docking mechanism 30 is used to connect the brewing box 20 to the water supply pipe inside the main unit. A through hole (water inlet) is provided on the top surface of the brewing box 20 for connecting to the water supply pipe inside the main unit. For this purpose, see [reference needed]. Figures 1 to 8 The docking mechanism 30 includes a connector 31, a knob 32, a drive linkage 38, and a guide post 33. The connector 31 includes a connector seat, a first connector for connecting to a water supply pipe inside the main unit, and a second connector for connecting to a through hole. The first and second connectors are in fluid communication. The first connector can be fixedly mounted on the side of the connector seat for easier connection to the water supply pipe inside the main unit. The second connector is located on the side of the connector seat near the brewing box 20 for better connection to the brewing box 20. As an example, the second connector extends downward from the bottom of the connector seat.

[0041] Please see Figure 1-8 In one embodiment of this utility model, the knob 32 includes an operating part located outside the housing 11 and a first connecting shaft extending from the outside of the housing 11 into the housing 11. The operating part and the first connecting shaft can be an integral structure. The operating part can be configured as a strip-shaped structure, with one end of the operating part fixedly connected to the first connecting shaft, thus allowing for easier rotation of the first connecting shaft via the operating part. The first connecting shaft rotatably engages with a hole opened on the housing 11. The first connecting shaft can be a circular structure for better fit with the housing 11.

[0042] Please see Figure 1-8In one embodiment of this utility model, the drive linkage 38 includes a drive part and a second connecting shaft connecting the drive part and the knob 32. The first connecting shaft and the second connecting shaft are connected to each other, so that the knob 32 and the drive linkage 38 can rotate synchronously. The first connecting shaft and the second connecting shaft can be fixedly connected, such as by welding. They can also be detachably connected, such as by threaded connection, plug-in, or snap-fit, and a locking element can be provided for locking. Optionally, the end of the first connecting shaft away from the operating part is provided as a plug, and the end of the second connecting shaft away from the drive part has a plug hole. The first connecting shaft is connected by inserting the plug into the plug hole, and the side can be locked by a locking element such as a screw or pin. The cross-sectional shape of the plug and the plug hole is non-circular (such as square, triangular, polygonal, etc.), so that after the plug is inserted into the plug hole, the knob 32 and the drive linkage 38 can rotate synchronously.

[0043] Please see Figure 1-8 In one embodiment of this utility model, the driving part and the second connecting shaft can be an integral structure. The driving part can be a single unit or two units arranged at intervals. Preferably, the driving linkage 38 includes two driving parts arranged at intervals to better connect with the connector 31 and ensure stability during the operation of the driving connector 31. The two driving parts are fixedly connected. A first connecting post is fixedly provided on the opposite sides of the two driving parts, and the axis of the first connecting post is not coaxial with the axis of the first connecting shaft, thereby causing the driving part to change its position in the height direction as the knob 32 rotates.

[0044] Please see Figure 1-8 In one embodiment of this utility model, a second connecting post is fixedly disposed on the connector seat. The second connecting post is disposed on one side of the connector seat or fixedly disposed on opposite (corresponding to the driving part) sides of the connector seat, and these two sides are not the same side as the side where the second connector is located. Preferably, the connector seat (as an example) Figure 7 The left and right ends of the middle section are each fixed with a second connecting post to ensure the stability of the movement after being connected to the drive linkage 38.

[0045] Please see Figure 1-8In one embodiment of this utility model, a transmission member 34 is provided between the coupling 31 and the driving part of the driving link 38. Both ends of the transmission member 34 are rotatably connected, that is, both ends of the transmission member 34 are rotatably engaged with the first connecting post and the second connecting post, respectively. The transmission member 34 rotatably connects the driving part and the coupling 31, realizing transmission between them. The transmission process is effortless and less prone to jamming. Specifically, through holes can be formed at both ends of the transmission member 34, which are fitted onto the connecting posts. A retaining spring or a retaining pin can then be provided at the outer end of the connecting post to limit the transmission member 34. Specifically, the transmission member 34 can be a long, strip-shaped sheet structure to reduce the space required for installation.

[0046] Please see Figure 1-8 In one embodiment of this utility model, a limiting head 35 is fixedly provided on the side wall of the connector seat corresponding to the second connecting post. A limiting slot is formed on the connecting rod between the two through holes, and the position and size of the limiting slot are consistent with the position and size of the limiting head 35. By providing the limiting head 35, the driving part can play a limiting role in the process of rotating and driving the connector 31 through the transmission member 34. Furthermore, a micro switch 36 can be provided on the side of the second connecting shaft. The micro switch 36 is located inside the housing 11, and a cam is fixedly provided at the corresponding position on the second connecting shaft of the driving connecting rod 38. The cam and the second connecting shaft can be an integral structure. Thus, when the second connecting shaft rotates, the cam rotates synchronously, and can touch or leave the contact of the micro switch 36 during the rotation, thereby providing a position signal when needed.

[0047] Please see Figure 1-8 In one embodiment of this utility model, a guide post 33 is disposed inside the housing 11 and can pass through the connector seat of the connector 31, with the two slidably connected. The guide post 33 is used to guide the up-and-down movement of the connector 31. The guide post 33 can be fixedly connected to the housing 11 via a guide seat. The number of guide posts 33 can be one or more, in order to provide a more stable guiding function. As an example, there are two guide posts 33, which are respectively disposed on both sides of the second connector.

[0048] Please see Figure 1-8In one embodiment of this utility model, the housing 11 is also provided with an installation port, through which the second connector of the connector 31 can pass and connect to the brewing box 20. During installation, the brewing box 20 is first placed in the docking chamber to complete the mechanical connection with the main unit. Then, the knob 32 is rotated, which drives the drive rod 38 to rotate. Since the first connecting post on the drive part of the drive rod 38 is not coaxial with the first connecting shaft of the knob 32, the first connecting post has a vertical position change as the drive part rotates. This change is transmitted through the transmission member 34. Because the connector 31 is limited by the guide post 33, it can move up and down, thereby inserting and disengaging from the installation port (brewing box 20). During installation, the second connector of the connector 31 descends through the body 10 and inserts into the through hole of the brewing box 20. When in place, the cam of the drive rod 38 will touch the contact of the micro switch 36, thereby giving a connection signal.

[0049] Please see Figure 1-8 In one embodiment of this utility model, the term "fluid connectivity" refers to the spatial relationship between two components or parts (hereinafter referred to as the first part and the second part, respectively), that is, a fluid (gas, liquid, or a mixture of both) can flow from the first part along a flow path and / or be transported to the second part. This can be a direct connection between the first part and the second part, or an indirect connection between the first part and the second part through at least one third party. The third party can be a fluid channel such as a pipe, channel, conduit, guide, hole, or groove, or a chamber or combination thereof that allows fluid to flow through.

[0050] Please see Figure 9 In one embodiment of this utility model, when this application is used as a portable coffee machine, it inevitably experiences significant shaking during transport. Sufficient sealing is required between the brewing box 20 and the second connector to prevent upward leakage of materials. Leakage can easily leave residue, leading to poor hygiene, and cleaning the second connector is relatively difficult. Therefore, a barrier ring 37 is provided at the end of the second connector away from the connector seat. The barrier ring 37 is made of a deformable flexible material, such as rubber or other similar materials. This ensures that while providing a sealing effect, it does not affect the up-and-down movement of the second connector. Furthermore, the barrier ring 37 can be detachably connected to the second connector, such as through a sleeve, snap-fit, or threaded connection. This facilitates the disassembly and cleaning of the barrier ring 37. Specifically, the barrier ring 37 may include a first barrier portion and a second barrier portion. The first barrier portion has an arc-shaped structure and can be located at the lower end to fully exert the barrier effect. The second barrier portion has a sheet-like annular structure and is located at the upper end to further enhance the barrier effect.
