[0027] The coffee machine in the prior art can automatically control the cleaning of the water outlet, but the cleaning structure of the water outlet of the coffee machine is complicated, resulting in a complex structure and high cost of the coffee machine.

[0028] Based on the above reasons, the embodiment of the present application provides a residual water discharge structure of a coffee machine, which includes a pressure relief component, the pressure relief component includes a pressure relief water outlet pipe, a pressure relief nozzle, a pressure relief nozzle spring and a pressure relief nozzle fixed head, the pressure relief nozzle is slidably connected to the pressure relief water outlet pipe, the pressure relief nozzle fixed head is arranged on the pressure relief water outlet pipe and is used to limit the pressure relief nozzle, the pressure relief nozzle spring is used to support the pressure relief nozzle to reset, a first pressure relief pipeline is arranged on the side wall of the pressure relief water outlet pipe, a second pressure relief pipeline is arranged on the side wall of the pressure relief nozzle, when the pressure relief nozzle slides on the pressure relief water outlet pipe, the first pressure relief pipeline and the second pressure relief pipeline are staggered and not connected or butted and connected to discharge residual water.

[0030] The following is a detailed description of a residual water discharge structure of a coffee machine provided in an embodiment of the present application with reference to specific examples.

[0031] Figure 1 A schematic diagram of a three-dimensional decomposition structure of a residual water discharge structure of a coffee machine provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the residual water discharge structure of the coffee machine includes a pressure relief component 9, which includes a pressure relief water outlet pipe 94, a pressure relief nozzle 95, a pressure relief nozzle spring 96 and a pressure relief nozzle fixing head 97. The pressure relief nozzle 95 is slidably connected to the pressure relief water outlet pipe 94, the pressure relief nozzle fixing head 97 is provided on the pressure relief water outlet pipe 94 and is used to limit the pressure relief nozzle 95, the pressure relief nozzle spring 96 is used to support the pressure relief nozzle 95 to reset, a first pressure relief pipeline 941 is provided on the side wall of the pressure relief water outlet pipe 94, and a second pressure relief pipeline 951 is provided on the side wall of the pressure relief nozzle 95. When the pressure relief nozzle 95 slides on the pressure relief water outlet pipe 94, the first pressure relief pipeline 941 and the second pressure relief pipeline 951 are staggered and disconnected or butt-connected to discharge residual water.

[0032] like Figure 1 As shown, structurally, the residual water discharge structure of the coffee machine includes a pressure relief component 9, and the pressure relief component 9 includes a pressure relief water outlet pipe 94, a pressure relief nozzle 95, a pressure relief nozzle spring 96 and a pressure relief nozzle fixing head 97. The pressure relief water outlet pipe 94 is used to discharge residual water on the pipeline for conveying coffee liquid.

[0033] Structurally, the pressure relief nozzle 95 is slidably connected to the pressure relief water outlet pipe 94 , and the pressure relief nozzle fixing head 97 is provided on the pressure relief water outlet pipe 94 and is used to limit the pressure relief nozzle 95 so that the pressure relief nozzle 95 will not be separated from the pressure relief water outlet pipe 94 .

[0034] Structurally, the pressure relief nozzle spring 96 is used to support the pressure relief nozzle 95 to reset, so that the pressure relief nozzle 95 can be reset under the push of the pressure relief nozzle spring 96 after sliding along the pressure relief water outlet pipe 94 .

[0035] Exemplarily, the pressure relief nozzle spring 96 can be sleeved and connected to the pressure relief water outlet pipe 94, or the pressure relief nozzle spring 96 can also be positioned by a spring positioning structure alone. The embodiment of the present application does not limit the positioning method of the pressure relief nozzle spring 96.

[0036] Figure 2 This is a schematic cross-sectional view of a residual water discharge structure of a coffee machine provided in an embodiment of the present application. Figure 3 A schematic diagram of the working process of a residual water discharge structure of a coffee machine provided in an embodiment of the present application is shown in FIG. Figures 1 to 3 As shown, a first pressure relief pipeline 941 is provided on the side wall of the pressure relief outlet pipe 94 , and a second pressure relief pipeline 951 is provided on the side wall of the pressure relief nozzle 95 . The first pressure relief pipeline 941 and the second pressure relief pipeline 951 cooperate with each other to discharge residual water from the pressure relief outlet pipe 94 .

[0037] When the pressure relief nozzle 95 slides on the pressure relief water outlet pipe 94 , the first pressure relief pipeline 941 and the second pressure relief pipeline 951 are offset from each other and are not connected, and the pressure relief water outlet pipe 94 does not discharge residual water.

[0038] When the pressure relief nozzle 95 slides on the pressure relief water outlet pipe 94, the first pressure relief pipeline 941 and the second pressure relief pipeline 951 can also be connected and connected to discharge the residual water, thereby cleaning the residual water in the coffee delivery pipeline.

[0039] The beneficial effect brought about by the above implementation method is that the pressure relief pipeline is opened or closed by sliding the pressure relief nozzle on the pressure relief water outlet pipe, which simplifies the structure for discharging residual water and simplifies the structure of the coffee machine.

[0040] The beneficial effect brought about by the above-mentioned implementation method is that the pressure relief pipeline is opened by sliding the pressure relief nozzle on the pressure relief water outlet pipe, which is convenient for relieving the pressure of the coffee delivery pipeline, avoiding the pipeline of the coffee machine being in a high-pressure state for a long time during use, and improving the service life of the coffee machine.

[0041] In some implementations, the pressure relief water outlet pipe 94 is disposed on the extraction cartridge support assembly 3, on which the extraction cartridge support assembly 4 and the extraction cartridge support bypass 301 are disposed, the extraction cartridge support bypass 301 being used to output the coffee liquid obtained by extracting coffee with the extraction cartridge support assembly 4, and the pressure relief water outlet pipe 94 is connected to the extraction cartridge support bypass 301.

[0042] Figure 4 FIG. 1 is a schematic diagram of a three-dimensional structure of an extraction cartridge support assembly in an embodiment of the present application. Figure 2and Figure 4 As shown, in terms of structure, the pressure relief water outlet pipe 94 is arranged on the extraction cartridge support assembly 3, and the extraction cartridge support assembly 3 is a fixed structure for extracting coffee. The extraction cartridge support assembly 3 is provided with an extraction cartridge assembly 4 and an extraction cartridge support bypass 301, the extraction cartridge assembly 4 is a working assembly for extracting coffee, and the extraction cartridge support bypass 301 is used to output the coffee liquid extracted by the extraction cartridge assembly 4. The pressure relief water outlet pipe 94 is connected to the extraction cartridge support bypass 301, so that the pressure relief water outlet pipe 94 can drain residual water and clean the coffee delivery pipeline on the extraction cartridge support bypass 301.

[0043] The beneficial effect brought about by the above implementation method is that the pressure relief water outlet pipe can drain the residual water and clean the coffee delivery pipeline of the extraction cartridge bracket bypass on the extraction cartridge bracket assembly.

[0044] In some implementations, the pressure relief assembly 9 further includes a pressure relief push rod 91 , which pushes the pressure relief nozzle 95 to slide on the pressure relief water outlet pipe 94 when the pressure relief push rod 91 moves axially.

[0045] like Figure 1 As shown, structurally, the pressure relief assembly 9 also includes a pressure relief push rod 91 , which is a working component of the residual water discharge structure. The pressure relief push rod 91 can push the pressure relief nozzle 95 to slide on the pressure relief water outlet pipe 94 .

[0046] Exemplarily, the pressure relief push rod 91 can be other structural components of the coffee machine. As other structural components of the coffee machine, the pressure relief push rod 91 can directly squeeze the pressure relief nozzle 95, push the pressure relief nozzle 95 to discharge residual water to the pressure relief outlet pipe 94, and improve the convenience of the residual water discharge operation of the coffee machine.

[0047] The beneficial effect brought about by the above-mentioned implementation method is that the pressure relief nozzle is pushed by the pressure relief push rod on the coffee machine, so that the residual water discharge structure and other structures of the coffee machine cooperate with each other to discharge the residual water, thereby improving the convenience of the residual water discharge process of the coffee machine.

[0048] In some implementations, the extraction cylinder bracket assembly 3 is disposed on the slider 23, and the slider 23 is provided with a pressure relief push rod hole 231 and a limit rod hole 232. The pressure relief push rod 91 is slidably connected in the pressure relief push rod hole 231, and a limit rod slide groove 911 is provided on the pressure relief push rod 91. The pressure relief assembly 9 also includes a pressure relief push rod spring 92 and a limit rod 93. The limit rod 93 is inserted into the limit rod hole 232 and is slidably connected to the limit rod slide groove 911. The pressure relief push rod spring 92 is used to support the pressure relief push rod 91 to reset.

[0049] like Figure 1 As shown, structurally, the extraction cartridge support assembly 3 is disposed on the slider 23, so that the extraction cartridge support assembly 3 can move along with the slider 23 during the process of extracting coffee.

[0050] Structurally, the slider 23 is provided with a pressure relief push rod hole 231 and a limit rod hole 232. The pressure relief push rod 91 is slidably connected in the pressure relief push rod hole 231, so that the pressure relief push rod 91 can be guided by the pressure relief push rod hole 231. The pressure relief push rod 91 can push the pressure relief nozzle 95 to slide on the pressure relief water outlet pipe 94 under the guidance of the pressure relief push rod hole 231.

[0051] Structurally, the pressure relief assembly 9 further includes a pressure relief push rod spring 92 and a limiting rod 93 . The pressure relief push rod 91 is provided with a limiting rod slide groove 911 , which is used to limit the pressure relief push rod 91 .

[0052] like Figure 1 and Figure 2 As shown, the limiting rod 93 is inserted into the limiting rod hole 232 and is slidably connected to the limiting rod sliding groove 911 , so that the limiting rod 93 can limit the stroke of the pressure relief ejector rod 91 within the length range of the limiting rod hole 232 .

[0053] like Figure 1 and Figure 2 As shown, the pressure relief push rod spring 92 is used to push the pressure relief push rod 91 to reset, so that the pressure relief push rod 91 can reset after pushing the pressure relief nozzle 95 to facilitate the subsequent coffee extraction cycle.

[0054] The beneficial effect brought about by the above-mentioned implementation method is that the pressure relief push rod can be guided through the pressure relief push rod hole, and the limit rod can limit the stroke of the pressure relief push rod within the length range of the limit rod hole, thereby improving the stability of the pressure relief push rod during operation and facilitating the control of the pressure relief process.

[0055] The beneficial effect brought about by the above-mentioned implementation method is that the pressure relief push rod can cooperate with other working structures of the coffee machine to relieve pressure on the coffee delivery pipeline, thereby improving the structural compactness of the coffee machine.

[0056] In some implementations, the extraction tube support assembly 3 is rotatably connected to the slider 23, and the pressure relief water outlet pipe 94, the pressure relief nozzle 95, the pressure relief nozzle spring 96 and the pressure relief nozzle fixing head 97 rotate together with the extraction tube support assembly 3 relative to the slider 23. When the extraction tube support assembly 3 rotates to the extraction position, the pressure relief push rod 91 can push the pressure relief nozzle 95 to stop draining residual water from the pressure relief nozzle 95; when the pressure relief push rod 91 is separated from the pressure relief nozzle 95, the pressure relief nozzle spring 96 pushes the pressure relief nozzle 95 to return to its original position to drain residual water from the pressure relief nozzle 95.

[0057] like Figure 1 As shown, structurally, the extraction cartridge support assembly 3 is rotatably connected to the slider 23 , so that the extraction cartridge support assembly 3 can rotate relative to the slider 23 , thereby facilitating the collection and extraction of coffee powder through the extraction cartridge support assembly 3 .

[0058] At work, if Figure 1 As shown by the arrow indicating the direction of rotation, the pressure relief water pipe 94, the pressure relief nozzle 95, the pressure relief nozzle spring 96 and the pressure relief nozzle fixing head 97 rotate together with the extraction tube support assembly 3 relative to the slider 23, thereby ensuring the stability of the pressure relief of the coffee delivery pipeline on the extraction tube support assembly 3.

[0059] like Figure 2 As shown, the extraction cartridge support assembly 3 is in the extraction position, at which time the pressure relief push rod 91 can push the pressure relief nozzle 95 to slide on the pressure relief water outlet pipe 94 , and at this time the pressure relief nozzle 95 can seal the pressure relief water outlet pipe 94 .

[0060] like Figure 3 As shown in Figure a, when the extraction tube bracket assembly 3 is rotated to the angle for coffee extraction, the pressure relief push rod 91 pushes the pressure relief nozzle 95 to slide on the pressure relief water outlet pipe 94, and the first pressure relief pipeline 941 and the second pressure relief pipeline 951 are staggered and disconnected from each other, and the pressure relief push rod 91 can push the pressure relief nozzle 95 to stop discharging residual water from the pressure relief water outlet pipe 94.

[0061] like Figure 3 As shown in Figure b, when the pressure relief push rod 91 is separated from the pressure relief nozzle 95, the pressure relief nozzle spring 96 pushes the pressure relief nozzle 95 to reset, so that the first pressure relief pipeline 941 and the second pressure relief pipeline 951 are connected to each other to discharge residual water from the pressure relief outlet pipe 94.

[0062] The beneficial effect brought about by the above-mentioned implementation method is that when the extraction cartridge bracket assembly rotates to the extraction position, the pressure relief push rod can push the pressure relief nozzle to slide on the pressure relief water outlet pipe, thereby sealing the pressure relief water outlet pipe, facilitating the output of finished coffee, so that the residual water discharge structure can be used in conjunction with the coffee extraction process, thereby improving the use effect of the coffee machine.

[0063] The beneficial effect brought about by the above-mentioned implementation method is that when the pressure relief push rod is separated from the pressure relief nozzle, the pressure relief nozzle spring pushes the pressure relief nozzle to reset, so that the first pressure relief pipeline and the second pressure relief pipeline are connected to each other to discharge residual water from the pressure relief outlet pipe, so that the residual water discharge structure can be used in conjunction with the coffee extraction process, thereby improving the use effect of the coffee machine.

[0064] In some implementations, a bypass connector 81 is provided on the extraction cartridge support assembly 3. The bypass connector 81 is connected to the extraction cartridge support bypass 301. The bypass connector 81 is used to connect to the sliding water outlet pipe 82 to transport coffee liquid. An extension tube 823 is provided at the end of the sliding water outlet pipe 82. When the bypass connector 81 is connected to the sliding water outlet pipe 82 to transport coffee liquid, the extension tube 823 pushes the pressure relief push rod 91.

[0065] like Figure 2 and Figure 4As shown, structurally, a bypass connector 81 is provided on the extraction cartridge support assembly 3, and the bypass connector 81 is connected to the extraction cartridge support bypass 301. The bypass connector 81 is used to connect to the sliding water outlet pipe 82 to transport coffee liquid, and the bypass connector 81 can position the sliding water outlet pipe 82.

[0066] Structurally, an extension tube 823 is provided at the end of the sliding water outlet pipe 82. When the bypass joint 81 and the sliding water outlet pipe 82 are connected to convey coffee liquid, the extension tube 823 pushes the pressure relief push rod 91. The sliding water outlet pipe 82 is used to convey the finished coffee outputted from the extraction cartridge holder bypass 301, so that the sealing of the extraction cartridge holder bypass 301 can be ensured when the finished coffee is output, thereby avoiding coffee leakage.

[0067] The beneficial effect brought about by the above implementation method is that when the bypass joint and the sliding water outlet pipe are connected to convey the coffee liquid, the extension tube pushes the pressure relief push rod, so that the sealing of the extraction cartridge bracket bypass can be ensured when the finished coffee is output, thereby avoiding coffee leakage.

[0068] In some implementations, a bypass joint sleeve 811 is provided on the bypass joint 81 , and the extension tube 823 passes through the bypass joint sleeve 811 and pushes the pressure relief push rod 91 .

[0069] like Figure 2 As shown, structurally, a bypass joint sleeve 811 is provided on the bypass joint 81, and the bypass joint sleeve 811 can position the sliding water outlet pipe 82. After the extension pipe 823 passes through the bypass joint sleeve 811, it pushes the pressure relief push rod 91, thereby improving the stability of the residual water discharge structure.

[0070] The beneficial effect brought about by the above implementation method is that the extension pipe pushes the pressure relief push rod after being positioned through the bypass joint sleeve, thereby improving the stability of the residual water discharge structure.

[0071] In some implementations, a bypass joint delivery pipe 811a is provided on the inner wall of the bypass joint sleeve 811, and a sliding water outlet pipe interface 822 is provided on the outer wall of the sliding water outlet pipe 82. When the sliding water outlet pipe 82 is extended into the bypass joint sleeve 811, the bypass joint delivery pipe 811a and the sliding water outlet pipe interface 822 are connected to each other.

[0072] like Figure 2 As shown, a bypass joint delivery pipe 811a is provided on the inner side wall of the bypass joint sleeve 811, and the bypass joint delivery pipe 811a is used to output the finished coffee.

[0073] Structurally, a sliding water outlet pipe interface 822 is provided on the outer side wall of the sliding water outlet pipe 82 , and the sliding water outlet pipe interface 822 is used to introduce finished coffee into the sliding water outlet pipe 82 .

[0074] When the sliding water outlet pipe 82 extends into the bypass joint sleeve 811, the bypass joint delivery pipe 811a and the sliding water outlet pipe interface 822 are connected to each other, so that the bypass joint sleeve 811 can ensure the sealing performance during coffee delivery.

[0075] The beneficial effect brought about by the above-mentioned implementation method is that the bypass joint sleeve can cooperate with the sliding water outlet pipe to ensure the sealing during coffee delivery.

[0076] In some implementations, a pressure relief nozzle top block 952 is provided on the pressure relief nozzle 95 , and the pressure relief nozzle top block 952 protrudes laterally from the pressure relief nozzle 95 . The pressure relief top rod 91 can push the pressure relief nozzle top block 952 to drive the pressure relief nozzle 95 to slide on the pressure relief water outlet pipe 94 .

[0077] like Figure 1 and Figure 4 As shown, structurally, a pressure relief nozzle 95 is provided with a pressure relief nozzle top block 952, and the pressure relief nozzle top block 952 protrudes laterally from the pressure relief nozzle 95. The pressure relief nozzle 95 is easily pushed by the pressure relief nozzle top block 952, and the pressure relief push rod 91 can push the pressure relief nozzle top block 952 to drive the pressure relief nozzle 95 to slide on the pressure relief water outlet pipe 94.

[0078] The beneficial effect brought about by the above implementation method is that the pressure relief nozzle can be driven to slide on the pressure relief water outlet pipe by pushing the pressure relief nozzle top block.

[0079] The embodiment of the present application also provides a coffee machine, which includes the above-mentioned residual water discharge structure of the coffee machine.
