Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] The extraction head of the existing coffee machine cannot release the high-pressure water flow when in use, which may easily cause leakage in the coffee machine pipeline when the coffee machine is used for a long time, thus affecting the normal use of the coffee machine.

[0029] Based on the above reasons, the embodiment of the present application provides a coffee machine extraction head structure, which includes an extraction head assembly, which includes a water inlet pipe, a seat body and an extraction head, the water inlet pipe is arranged on the seat body, and an extraction head conduit is arranged on the extraction head, the extraction head conduit and the water inlet pipe are slidably sleeved, and a pressure relief bypass is arranged on the side wall of the water inlet pipe, and when the extraction head conduit slides along the water inlet pipe, the extraction head conduit can close or open the pressure relief bypass. The coffee machine extraction head structure in the embodiment of the present application can timely relieve the pressure of the pipeline when working, so that the water flow pressure in the extraction head pipeline of the coffee machine can be released in time, avoiding the leakage caused by the pipeline of the coffee machine being in a high pressure state for a long time, and improving the use effect of the coffee machine.

[0030] In some scenarios, a coffee machine extraction head structure of an embodiment of the present application can be applied to the extraction structure of the coffee machine. By timely releasing the pressure of the extraction structure of the coffee machine, it can prevent the pipeline from being in a high-pressure state for a long time and leaking, thereby increasing the service life of the extraction structure of the coffee machine.

[0031] The following is a detailed description of a coffee machine extraction head structure provided in an embodiment of the present application with reference to specific examples.

[0032] Figure 1 A schematic diagram of a three-dimensional decomposition structure of a coffee machine extraction head structure provided in an embodiment of the present application, such as Figure 1 As shown, the extraction head structure of the coffee machine includes an extraction head assembly 5, and the extraction head assembly 5 includes a water inlet pipe 53, a base body 51 and an extraction head 52. The water inlet pipe 53 is arranged on the base body 51, and an extraction head duct 522 is provided on the extraction head 52. The extraction head duct 522 and the water inlet pipe 53 are slidably connected, and a pressure relief bypass 531 is provided on the side wall of the water inlet pipe 53. When the extraction head duct 522 slides along the water inlet pipe 53, the extraction head duct 522 can close or open the pressure relief bypass 531.

[0033] like Figure 1 As shown, the extraction head structure of the coffee machine includes an extraction head assembly 5, which is a working structure for extracting coffee. The extraction head assembly 5 includes a water inlet pipe 53, a base body 51 and an extraction head 52. The water inlet pipe 53 is arranged on the base body 51, and the extraction head assembly 5 can be supplied with water for extraction through the water inlet pipe 53.

[0034] like Figure 1 As shown, the extraction head 52 is provided with an extraction head duct 522, which is used to discharge the extraction water to the side where the coffee powder is located for coffee extraction. The extraction head duct 522 and the water inlet pipe 53 are slidably connected, so that the length of the connection between the extraction head duct 522 and the water inlet pipe 53 can be adjusted when extracting coffee.

[0035] Exemplarily, a sealing ring may be provided on the outer side wall of the extraction head conduit 522 to ensure the sealing between the extraction head conduit 522 and the water inlet pipe 53 .

[0036] like Figure 1 As shown, a pressure relief bypass 531 is provided on the side wall of the water inlet pipe 53, and the pressure relief bypass 531 is used to discharge and relieve the pressure of the extraction water in the extraction head conduit 522 and the water inlet pipe 53 to avoid leakage caused by excessive pipeline pressure of the coffee machine.

[0037] During operation, when the extraction head duct 522 slides along the water inlet pipe 53, the extraction head duct 522 can close or open the pressure relief bypass 531. When the pressure relief bypass 531 is closed, the water flow of the water inlet pipe 53 enters the extraction head duct 522 for coffee extraction; when the pressure relief bypass 531 is opened, the water flow in the water inlet pipe 53 and the extraction head duct 522 is discharged through the pressure relief bypass 531 to relieve pressure.

[0038] Figure 2 A schematic diagram of the working process of a coffee machine extraction head structure provided in an embodiment of the present application is shown in FIG. Figure 2 As shown in a, when the pressure relief bypass 531 is closed, the water flow of the water inlet pipe 53 enters the extraction head conduit 522 to extract coffee; Figure 2 As shown in b, the water flow in the water inlet pipe 53 and the extraction head conduit 522 is discharged and depressurized through the pressure relief bypass 531.

[0039] In some implementations, the extraction head assembly 5 is disposed on the frame 1, and the extraction head assembly 5 is used to cooperate with the extraction cylinder 41 to extract coffee.

[0040] Figure 4 A schematic diagram of a coffee machine extraction head structure in use according to an embodiment of the present application is shown in FIG. Figure 5 A schematic diagram of a top view of a coffee machine extraction head structure provided in an embodiment of the present application is shown in FIG. Figure 4 and Figure 5 As shown, the extraction head assembly 5 is arranged on the frame 1, and the extraction head assembly 5 can penetrate into the extraction cylinder 41. The extraction head assembly 5 is used to cooperate with the extraction cylinder 41 to extract coffee.

[0041] The beneficial effect brought about by the above-mentioned implementation method is that the pressure relief bypass can discharge and relieve the pressure of the extraction water in the extraction head conduit and the water inlet pipe, thereby avoiding leakage caused by excessive pipeline pressure during the coffee extraction process.

[0042] In some implementations, a conduit bypass 522a is provided on the side wall of the extraction head conduit 522. When the conduit bypass 522a and the pressure relief bypass 531 are staggered, the pressure relief bypass 531 is closed by the extraction head conduit 522. When the conduit bypass 522a and the pressure relief bypass 531 are aligned, the conduit bypass 522a and the pressure relief bypass 531 are connected.

[0043] Figure 3 for Figure 2 A schematic diagram of the local structure of a coffee machine extraction head structure at A, as shown in Figure 3 As shown, a conduit bypass 522 a is provided on the side wall of the extraction head conduit 522 , and the conduit bypass 522 a is used to discharge water flow to relieve the pressure of the extraction head conduit 522 and the water inlet pipe 53 .

[0044] During operation, when the conduit bypass 522a and the pressure relief bypass 531 are staggered, the pressure relief bypass 531 is closed through the extraction head conduit 522. At this time, water can only flow into the extraction head conduit 522 through the water inlet pipe 53, and the coffee extraction process is carried out.

[0045] like Figure 3 As shown, when the conduit bypass 522a and the pressure relief bypass 531 are aligned, the conduit bypass 522a and the pressure relief bypass 531 are connected, and water flows out through the conduit bypass 522a and the pressure relief bypass 531, thereby achieving pressure relief on the extraction head structure of the coffee machine.

[0046] The beneficial effect brought about by the above-mentioned implementation method is that by arranging a conduit bypass on the side wall of the extraction head conduit and relieving pressure on the pressure relief bypass through the conduit bypass, the accuracy of pressure relief through the pressure relief bypass can be improved and the sealing effect of the pressure relief bypass can be ensured.

[0047] In some implementations, a guide portion 511 is provided on the base 51 , and the extraction head 52 is slidably connected to the guide portion 511 .

[0050] The beneficial effect brought about by the above implementation method is that the stability of the extraction head during coffee extraction can be improved through the guide part.

[0051] In some implementations, an extraction head guide rod 521 is provided on the extraction head 52. The extraction head guide rod 521 is slidably connected to the guide portion 511. An extraction head spring 523 is sleeved on the extraction head guide rod 521. The extraction head spring 523 is used to support the extraction head 52 to reset.

[0052] like Figure 1 As shown, structurally, an extraction head guide rod 521 is provided on the extraction head 52 , and the extraction head guide rod 521 is used to guide the extraction head 52 .

[0053] During operation, the extraction head guide rod 521 is slidably connected to the guide portion 511, so that the extraction head guide rod 521 and the extraction head 52 can move stably relative to the guide portion 511, thereby improving the stability of the extraction head 52 during operation.

[0054] like Figure 1 and Figure 2 As shown, an extraction head spring 523 is sleeved on the extraction head guide rod 521. The extraction head spring 523 is used to provide a restoring force for the extraction head 52. The extraction head spring 523 is used to prop up the extraction head 52 to reset. After coffee extraction, the extraction head 52 can be reset under the push of the extraction head spring 523, thereby facilitating the next coffee extraction.

[0055] The beneficial effect brought about by the above implementation method is that the extraction head guide rod and the guide part cooperate to improve the stability during operation.

[0056] The beneficial effect brought about by the above implementation method is that after the extraction of coffee, the extraction head can be reset under the push of the extraction head spring, thereby facilitating the next coffee extraction.

[0057] In some implementations, the extraction head assembly 5 further includes an extraction head filter sheet 54 . The extraction head filter sheet 54 is disposed at the end of the extraction head 52 . The extraction head conduit 522 is connected to one side of the extraction head filter sheet 54 .

[0058] like Figure 1 and Figure 2 As shown, structurally, the extraction head assembly 5 also includes an extraction head filter 54, and the extraction head filter 54 is used to prevent coffee powder from entering the extraction head 52 when the coffee powder is extracted.

[0059] Structurally, the extraction head filter 54 is arranged at the end of the extraction head 52, specifically close to one end of the extraction cylinder 41, and the extraction head duct 522 is connected to one side of the extraction head filter 54, so that the water flow discharged from the extraction head duct 522 can extract the coffee powder.

[0060] The beneficial effect brought about by the above implementation method is that the coffee powder can be prevented from entering the extraction head through the extraction head filter.

[0061] In some implementations, the extraction head assembly 5 further includes an extraction head micro switch 501 , and a top block 524 is provided on the extraction head guide rod 521 . The top block 524 can trigger the extraction head micro switch 501 as the extraction head guide rod 521 moves.

[0062] like Figure 1 and Figure 2 As shown, the extraction head assembly 5 further includes an extraction head micro switch 501 , through which the position of the extraction head 52 can be detected.

[0063] Exemplarily, the extraction head micro switch 501 can control the working state of the water pump when extracting coffee.

[0064] Structurally, a top block 524 is provided on the extraction head guide rod 521. The top block 524 can trigger the extraction head micro switch 501 as the extraction head guide rod 521 moves, so that the extraction head micro switch 501 can detect the positions of the top block 524 and the extraction head guide rod 521, thereby realizing the control of the extraction process.

[0065] The beneficial effect brought about by the above implementation method is that the extraction head micro switch and the top block cooperate with each other to detect the positions of the top block and the extraction head guide rod, thereby achieving precise control of the extraction process.

[0066] In some implementations, there are two extraction head guide rods 521 , and the top block 524 is connected to the ends of the two extraction head guide rods 521 , respectively.

[0067] like Figure 1 As shown, structurally, there are two extraction head guide rods 521 , so that the extraction head 52 can be guided by the cooperation of the two extraction head guide rods 521 .

[0068] like Figure 1 As shown, the top block 524 is respectively connected to the ends of the two extraction head guide rods 521, so that the top block 524 can be stably fixed by the two extraction head guide rods 521, and the extraction head springs 523 on the two extraction head guide rods 521 are limited by the top block 524, which simplifies the structure of the extraction head.

[0069] The beneficial effect brought about by the above implementation method is that the stability of the movement of the extraction head is improved by the two extraction head guide rods.

[0070] The beneficial effect brought about by the above implementation method is that the top block can be stably fixed by the two extraction head guide rods, and the extraction head springs on the two extraction head guide rods are limited by the top block, thereby simplifying the structure of the extraction head.

[0071] In some implementations, a top block mounting hole 524a is provided on the top block 524, and the top block mounting hole 524a and the extraction head guide rod 521 are connected by bolts.

[0072] like Figure 1 As shown, a top block mounting hole 524a is provided on the top block 524, and the top block mounting hole 524a is recessed on the top block 524. The top block mounting hole 524a and the extraction head guide rod 521 are connected by bolts, thereby reducing the volume of the top block 524 and the volume of the extraction head structure.

[0073] The beneficial effect brought about by the above implementation method is that the volume of the top block and the extraction head structure is reduced.

[0074] In some implementations, an extraction head connecting plate 522b is provided on the extraction head conduit 522, and the extraction head connecting plate 522b and the extraction head 52 are connected by bolts.

[0076] Exemplarily, the extraction head conduit 522 and the extraction head connecting plate 522b may be integrally formed.

[0077] The beneficial effect brought about by the above implementation manner is that the extraction head conduit can be easily fixed through the extraction head connecting plate.
