The embodiments described below by reference to the drawings are exemplary only, and are used only for explaining the present application, and cannot be understood as a limitation of the present application.

[0030] The embodiments of the present application are described below in detail. Figures 1 to 5 The embodiments of the present application are described below in detail.

[0031] An automatic drainage structure in the embodiments can be applied in a water making device such as a water dispenser.

[0032] The automatic drainage structure in the embodiments comprises:

[0033] A water receiving tray 1, wherein a drain hole 11 is arranged on the water receiving tray 1;

[0034] A drain pipe 2, wherein a water trap 21 is arranged in the middle of the drain pipe 2;

[0035] A drain pump (not shown in the figure), wherein a water pumping end of the drain pump is communicated with the drain hole 11 through the drain pipe 2;

[0036] A liquid level switch 4, which is arranged in the water receiving tray 1, is signal connected with the drain pump, and is used for controlling the start and stop of the drain pump.

[0037] The water collecting tray 1 is provided with a drain hole 11, which is communicated with a drain pump through a water trap 21. The water trap 21 separates the drain pump from the water collecting tray 1, so as to avoid the odor at the end where the drain pump is located from being emitted to the water collecting tray 1. When the water level in the water collecting tray 1 is high and the signal of the liquid level switch 4 changes, the liquid level switch 4 starts the drain pump, so as to make the water flow over the water trap 21 and be discharged, thereby realizing automatic drainage.

[0038] The automatic drainage structure comprises a branch pipe 22, one end of the branch pipe 22 being communicated with the drain pipe 2, and the communicated position of the branch pipe 22 with the drain pipe 2 being located between the drain pump and the water trap 21. The branch pipe 22 provides another port communicated with the drain pipe 2, so that the wastewater at other positions can be communicated with the branch pipe 22. The number of the branch pipe 22 can be one or more, which can be flexibly set according to actual needs.

[0039] Further, the automatic drainage structure further comprises a supporting plate 6, which is placed on the water collecting tray 1 and is provided with a water leakage hole 61. By arranging the supporting plate 6, some articles such as cups and kettles can be conveniently placed on the supporting plate 6.

[0040] The supporting plate 6 is placed on the water collecting tray 1, and it can be inconvenient to take out the supporting plate 6. Therefore, the supporting plate 6 is provided with a handle hole 62. The handle hole 62 is convenient for the user to put his finger through, so as to conveniently take up the supporting plate 6 from the water collecting tray 1, thereby enhancing the convenience of taking.

[0041] Further, the inner bottom surface of the water collecting tray 1 is provided with a protrusion 12, and the inner top side of the water collecting tray 1 is provided with a placing groove 13, in which the supporting plate 6 is placed. The protrusion 12 is used for supporting the supporting plate 6. Articles are usually placed in the middle part of the water collecting tray 1, and the supporting plate 6 is supported by the protrusion 12, so as to effectively improve the supporting strength of the supporting plate 6 and make the supporting plate 6 not easy to deform, thereby being more durable.

[0042] The inner side of the water collecting tray 1 is provided with a mounting port 14, the outer side of the mounting port 14 is provided with a surrounding bone 15, the surrounding bone 15 is provided with a water inlet gap 151, the liquid level switch 4 is located inside the surrounding bone 15, the liquid level switch 4 penetrates downward from the mounting port 14, and the liquid level switch 4 is in sealing connection with the mounting port 14. By arranging the surrounding bone 15 and arranging the liquid level switch 4 in the surrounding bone 15, the liquid level switch 4 can be protected by the surrounding bone 15, thereby improving the service life of the liquid level switch 4. The liquid level switch 4 penetrates downward from the mounting port 14, and the line of the liquid level switch 4 can be conveniently connected to an external controller.

[0043] Further, the automatic drainage structure further comprises a cap 5 covering the top of the surrounding bone 15, and a gap is left between the cap 5 and the inner bottom surface of the water pan 1 for water to flow into the interior of the surrounding bone 15. The cap 5 partially covers and tightly fits the top area of the surrounding bone 15, and the purpose of this design is to provide an additional protective layer to ensure that the liquid level switch 4 can be fully protected. By providing the cap 5, it can effectively prevent external debris, liquid or impact force from directly acting on the liquid level switch 4, thereby prolonging its service life and ensuring its normal operation.

[0044] Specifically, the mounting port 14 is provided with a grommet 16, the liquid level switch 4 comprises a core column 41, a dry reed, a float 42, a nut 43 and a sealing ring 44, the core column 41 passes through the grommet 16, the core column 41 is provided with a limiting bone and a sealing bone, both of which are located in the water pan 1, and the limiting bone is located above the sealing bone, the sealing ring 44 is located between the sealing bone and the grommet 16, and the sealing ring 44 is used to close the gap between the sealing bone and the grommet 16, the lower end of the core column 41 is provided with a screw thread, the screw thread is located outside the water pan 1, the nut 43 is threadedly connected with the screw thread, so that the sealing bone tightly presses the sealing ring 44; the dry reed is located at the lower side of the limiting bone and is arranged in the core column 41, and the float 42 is located between the sealing bone and the limiting bone support, and the float 42 slides along the core column 41. When the liquid level changes, the float 42 moves up and down along with the liquid surface. The float 42 contains a magnet inside, and when the float 42 rises or falls to a certain position, the magnet approaches or moves away from the dry reed, causing the contact points inside the dry reed to close or open. This closing or opening action can be detected by an external circuit, thereby realizing the monitoring and control of the liquid level. It can be understood that, in order to realize the start and stop of the drainage pump through the liquid level switch 4, the automatic drainage structure further comprises a controller, and the liquid level switch 4 and the drainage pump are signal-connected with the controller, and when the liquid level switch 4 changes the signal, the controller changes the start and stop state of the drainage pump. The controller can be an STM32 single-chip microcomputer or the like. The circuit for realizing the start and stop of the drainage pump by the controller receiving the signal change of the liquid level switch 4 can refer to the related technical solutions in the prior art.

[0045] Further, the drainage hole 11 is provided with a filter plate 6 to limit the debris in the water pan 1 from entering the drain pipe 2 through the drainage hole 11, thereby reducing the possibility of clogging of the drain pipe 2 and failure of the drainage pump.

[0046] The preferred embodiments of the present application are described in detail above, but the present disclosure is not limited to the embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application. These equivalent modifications or replacements are all included in the scope defined by the claims of the present disclosure.
