Detailed implementation manners

[0033] The following Figure 1-7 will describe the present utility model in detail.

[0034] A drainage device includes a base body 10 and a drainage body 20. A connecting base 101 is provided outside the base body 10. A fixing hole is provided on the connecting base 101. After a fastener passes through the fixing hole, the base body 10 is fixed to a coffee machine. The drainage body 20 is provided with a drainage channel 201. The drainage body 20 passes through the base body 10 and is pivotally connected to the base body 10. The drainage body 20 is provided with a clamping member 30. The base body 10 is provided with an initial slot position 1051 and a terminal slot position 1052. During the rotation of the drainage body 20, the clamping member 30 has a first position where it is clamped in the initial slot position 1051 and a second position where it is clamped in the terminal slot position 1052.

[0035] When the drainage body 20 is in the first position, the drainage body 20 is located outside the water tank 40 and the drainage body 20 is in a drainage closed state. When the drainage body 20 is in the second position, the drainage port of the drainage body 20 is located inside the water tank 40 and the drainage body 20 is in a drainage open state.

[0036] Therefore, the rotatable drainage body 20 provides convenience for the installation and disassembly of the water tank 40, improving the user experience.

[0037] In this embodiment, the base body 10 is provided with an installation groove 102, and the installation groove 102 is provided with an opening for passing through the drainage body 20. Opposite side walls of the installation groove 102 are provided with pivot holes 103. Both sides of the drainage body 20 are provided with rotating shafts 202 that are rotationally adapted to the pivot holes 103. Further, a guide groove 104 is provided on the side wall of the installation groove 102. The initial slot position 1051 and the terminal slot position 1052 are provided at both ends of the guide groove 104, and the clamping member 30 moves along the guide groove 104.

[0038] In this embodiment, a first guiding surface 1601 that gradually rises from the initial slot 1051 along the guiding slot 104 towards the terminal slot 1052 is provided in the guiding slot 104. A second guiding surface 1062 that gradually rises from the terminal slot 1052 along the guiding slot 104 towards the initial slot 1051 is also provided in the guiding slot 104. The connection point of the first guiding surface 1601 and the second guiding surface 1062 is located at the midpoint of the guiding slot 104. Such that as long as the rotation stroke of the drainage body 20 exceeds half of the full length of the guiding slot 104, the drainage body 20 can move towards the initial recess or the terminal recess under the guiding action of the first guiding surface 1601 or the second guiding surface 1062.

[0039] In this embodiment, convex portions are respectively provided on the opposite side surfaces of the drainage body 20. The end of the convex portion away from the drainage body 20 is an arc surface or a spherical surface, and the convex portion constitutes the engaging member 30. During the flipping process of the drainage body 20, an interference fit with a slight interference amount is formed between the convex portion and the guiding slot 104, or a transition fit is formed between the convex portion and the guiding slot 104.

[0040] In other embodiments, mounting holes are provided on the opposite side surfaces of the drainage body 20, and an elastic device is provided in the mounting holes. The elastic device constitutes the engaging member 30. The elastic device includes a compression spring and a clamping head. One end of the clamping head abuts against the compression spring, and the other end of the clamping head abuts against the guiding slot 104 under the action of the elastic force.

[0041] In this embodiment, a stop block 203 is provided on the surface of the drainage body 20 facing the water tank 40; during the installation and disassembly of the water tank 40, the water tank 40 abuts against the stop block 203, causing the drainage body 20 to change between a first position and a second position. Further, a connection head 204 is provided at the water inlet end of the drainage body 20 for connecting to a drainage pipe.

[0042] In this embodiment, an induction switch (not shown) is provided in the base body 10 for monitoring whether the drainage body 20 is in the first position or the second position. When the drainage body 20 is in the second position, the induction switch sends an opening signal to the coffee machine. Specifically, the induction switch includes an infrared switch, a microswitch, a Hall switch, or other switch devices that can be used to monitor the movement position of components. The related working principles belong to the conventional technical means in this field and will not be elaborated further.

[0043] A coffee machine (not shown) includes the drainage device as described above, and further includes a water tank 40. The water tank 40 is provided with a water inlet 401, and an actuating convex portion 402 extending outward is provided at the edge of the orifice of the water inlet 401. Specifically:

[0044] Step 1: When installing the water tank 40, the actuating convex portion 402 gradually approaches the stop block 203 of the drainage body 20, as Figure 5 shown;

[0045] Step 2. Continue to install the water tank 40. The actuating convex portion 402 abuts against the stop block 203 of the drain body 20, causing the clamping member 30 to disengage from the initial groove and abut against the first guiding surface 1601. The drain body 20 starts to rotate clockwise, as Figure 6 shown;

[0046] Step 3. Continue to install the water tank 40. The actuating convex portion 402 pushes the drain body 20 to continue rotating until its rotation stroke exceeds half of the full length of the guide groove 104. The clamping member 30 disengages from the first guiding surface 1601 and enters the second guiding surface 1062. Under the guiding action of the second guiding surface 1062, the drain body 20 automatically moves towards the terminal groove, causing the clamping member 30 to be clamped in the terminal groove. At this time, the drain body 20 is in the second position, that is, the drain opening state. The drain body 20 passes through the water inlet 401, so that the drain port of the drain body 20 is located inside the water tank 40, as Figure 7 shown.

[0047] When disassembling the water tank 40, the movement process of the drain body 20 is completely opposite to that when installing the water tank 40, that is, the actuating convex portion 402 abuts against the stop block 203 of the drain body 20 to make it rotate counterclockwise, causing the drain body 20 to rotate to the first position, so that the drain body 20 is located outside the water tank 40.

[0048] The above embodiments are only used to illustrate the technical concept and features of the present invention. The purpose is to enable those skilled in the art to understand the content of the present invention and implement it, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
