[0022] Embodiment 1:

[0023] Figure 1-Figure 4 The utility model shows a portable coffee machine with a water outlet adjustment device, comprising a shell 1 that can be assembled into a cylindrical shape, an adjustment ring 2 and a coffee cup 5. The shell 1 is provided with a water tank 11, a water pump 12, a shower head 13, a filter, a brewing shell 3 and a leak-proof valve core 4 from top to bottom. The brewing shell 3 is used to contain coffee liquid, and has a liquid outlet at its lower end. The leak-proof valve core 4 is arranged at the liquid outlet, and the leak-proof valve core 4 can move up and down. When the leak-proof valve core 4 is at the lowest point, the liquid outlet is blocked to prevent residual coffee liquid from dripping from the liquid outlet. When the leak-proof valve core 4 is lifted, the liquid outlet is connected and the coffee liquid can flow out normally.

[0024] The adjusting ring 2 is rotatably connected to the outer shell 1, and its outer edge has vertical lines, which can facilitate people to grasp and rotate the adjusting ring 2 to make it rotate. The middle part of the adjusting ring 2 has a rotating movable cavity, and a protrusion 21 is arranged in the rotating movable cavity. The protrusion 21 is eccentrically arranged relative to the rotating axis of the adjusting ring 2, and a stop block 41 is arranged at the lower end of the leak-proof valve core 4 corresponding to the protrusion 21. When the protrusion 21 rotates to the corresponding position of the stop block 41, the stop block 41 can be lifted and moved upward together with the leak-proof valve core 4. When the protrusion 21 is misaligned with the stop block 41, the leak-proof valve core 4 naturally falls down. By this means, the movement of the leak-proof valve core 4 can be controlled and the conduction of the liquid outlet can be controlled.

[0025] When the protrusion 21 cooperates with the stopper 41, it should have an inclined structure to facilitate the cooperation between the stopper 41 and the protrusion 21 to achieve the purpose of lifting the leak-proof valve core 4. The utility model arranges the inclined structure on the protrusion 21. Specifically, one side of the protrusion 21 relative to its rotation direction is set as a gentle slope 211. When the adjusting ring 2 rotates, the stopper 41 abuts against the bottom end of the gentle slope 211 and gradually rises along the gentle slope 211. Whether it rotates clockwise or counterclockwise can be set according to specific needs. The side opposite to the gentle slope 211 in the protrusion 21 is a vertical surface 212. After the stopper 41 rises to the highest point along the gentle slope 211, it rotates to the vertical surface 212 and falls rapidly. The user can hear the collision of the stopper 41 with the wall of the rotating active chamber, and obtain the information that the leak-proof valve core 4 has closed the liquid outlet.

[0026] The coffee cup 5 is detachably connected to the lower end of the adjustment ring 2 for containing brewed coffee. The upper end of the coffee cup 5 and the lower end of the adjustment ring 2 are matched with a clamping ring and a concave ring. The user can pull / press the coffee cup 5 hard to separate / connect the coffee cup 5 from the adjustment ring 2.

[0027] The upper and lower ends of the leak-stop valve core 4 respectively have an upper convex edge 43 and a lower convex edge 42, the upper convex edge 43 is located inside the brewing shell 3, and the lower convex edge 42 is located below the brewing shell 3, a sealing ring 45 is provided between the upper convex edge 43 and the brewing shell 3 for sealing the liquid outlet, and a reset spring 44 is provided between the lower convex edge 42 and the brewing shell 3, the reset spring 44 applies a downward elastic force to the leak-stop valve core 4, and the block 41 needs to overcome the elastic force of the reset spring 44 when moving upward along the gentle slope 211.

[0028] The filter basket 31 is arranged in the brewing shell 3 for containing coffee powder. The shower head 13 is arranged above the filter basket 31. The water pump 12 can introduce hot water for brewing into the shower head 13, and then spray it into the filter basket 31 through the shower head 13 to mix with the coffee powder to form coffee liquid. The coffee liquid passes through the filter basket 31 and enters the brewing shell 3.

[0029] Working principle:

[0030] The coffee liquid passes through the filter basket 31 and flows into the brewing shell 3. The liquid outlet of the brewing shell 3 is blocked by the leak-proof valve core 4. The coffee liquid will be temporarily stored in the brewing shell 3. After the brewing is completed, the user manually rotates the adjusting ring 2 to make the protrusion 21 lift the stopper 41, and the entire leak-proof valve core 4 moves upward. The liquid outlet is connected, and the coffee liquid flows down from the liquid outlet into the coffee cup 5. After most of the coffee liquid flows out, the user twists the adjusting ring 2 again to separate the protrusion 21 from the stopper 41. The leak-proof valve core 4 moves downward under the elastic force of the reset spring 44 and its own weight, blocks the liquid outlet, and prevents the residual coffee liquid from dripping.

[0031] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
