DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the following embodiments and accompanying drawings.

[0027] refer to Figures 1 to 5 A brewing assembly for a beverage machine with an anti-clogging function includes a base 1, an upper cover 2, and a brewing capsule 3. The base 1 has an upward-opening mounting cavity 101 formed inside. The opening cover of the mounting cavity 101 is provided with a capsule holder 9. The capsule holder 9 has an upward-opening placement cavity 901. The brewing capsule 3 is placed in the placement cavity 901. The capsule holder 9 has a ventilation hole 905 extending therethrough.

[0028] The upper cover 2 includes a movable cover 21 and a mounting member 22. One side of the movable cover 21 is hinged and movable on the base 1, so that the upper cover 2 can be opened and closed on the base 1, so that the user can open or close the upper cover 21 relative to the base; a locking mechanism 8 is provided on the other side of the movable cover 21. The locking mechanism 8 is used to lock or unlock the upper cover 2 and the base 1. The locking mechanism 8 is a prior art and will not be described in detail here.

[0029] A water pipe 4, a first needle 5 and a three-way pipe structure 7 are installed inside the movable cover 21. One end of the water pipe 4 extends out of the outside of the movable cover 21 for connection to an external water pump, and the other end of the water pipe 4 extends into the interior of the movable cover 21. The three-way pipe structure 7 is a T-shaped structure. The three-way pipe structure 7 is connected with an air intake input end 701, a liquid intake input end 702, and a liquid output end 703. The water pipe 4 is connected to the liquid intake input end 702, and the first needle 5 is connected to the liquid output end 703. The air intake input end 701 is connected with a one-way valve body 6. The water pipe 4, the first needle 5, and the one-way valve body 6 are connected through the three-way pipe structure 7.

[0030] The one-way valve body 6 can open or close according to changes in the internal pressure of the water pipe 4. When the internal pressure of the water pipe 4 is in a negative pressure state, the one-way valve body 6 allows air outside the water pipe 4 to enter the water pipe 4 through the one-way valve body 6. Preferably, the distance between the first needle 5 and the one-way valve body 6 is less than 20 cm. By optimizing the relative position between the one-way valve body 6 and the needle, the pressure required to open the one-way valve 6 can be reduced, thereby improving the response speed of the one-way valve body 6.

[0031] The mounting member 22 is disc-shaped and is screwed into the bottom surface of the movable cover 21. The top surface of the mounting member 22 is provided with a mounting seat 221 for the liquid output end 703 to be sleeved. The outer wall of the liquid output end 703 is provided with a first docking sleeve 704. The mounting seat 221 is sleeved into the inner wall of the first docking sleeve 704. The top surface of the mounting member 22 is provided with a second docking sleeve 223. The first docking sleeve 704 is sleeved into the inner wall of the second docking sleeve 223, and a sealing ring 705 is provided between the first docking sleeve 704 and the second docking sleeve 223. The sealing ring 705 is embedded in the outer wall of the first docking sleeve 704, and the sealing ring 705 is tightly pressed against the inner wall of the second docking sleeve 223 for sealing, thereby ensuring the sealing reliability between the liquid output end 703 and the mounting seat 221.

[0032] Another embodiment of the three-way pipe structure 7 is provided. The liquid outlet end 703 of the three-way pipe structure 7 is connected to a double joint structure 11 and a hose structure 12. The double joint structure 11 is hollow and tubular. The first end of the double joint structure 11 is connected to and communicates with the hose structure 12. The second end of the double joint structure 11 is inserted into the mounting seat 221 and communicates with the mounting hole 222. A first docking sleeve 704 is formed on the outer wall of the second end of the double joint structure 11. The first docking sleeve 704 and the second docking sleeve 223 are connected to guide the double joint structure 11 to be positioned and installed on the mounting seat 221, thereby ensuring that the three-way pipe structure 7 and the first needle 5 are spaced apart. The spacing between the three-way pipe structure and the first needle 5 can be predetermined by connecting a hose structure 12 of a corresponding length, facilitating the control of the spacing between the three-way pipe structure and the first needle 5 to within 20 cm.

[0033] The bottom of the inner wall of the mounting seat 221 is formed with a mounting hole 222 at a position opposite the liquid outlet 703 for securing the first needle 5. Preferably, the first needle 5 is embedded in the mounting hole 222. The interior of the first needle 5 is hollow, and the upper end of the first needle 5 is open. The inner wall of the opening mates with the inner wall of the mounting hole 222. The lower end of the first needle 5 is formed with a closed tip structure 501. The lower end of the first needle 5 is formed with two symmetrically arranged liquid outlets 502, which communicate with the interior of the first needle 5. When the mounting member 22 is connected to the movable cover 21, the liquid outlet 703 is inserted into the mounting seat 221, the outlet 703 communicates with the mounting hole 222, and the lower end of the first needle 5 protrudes from the lower surface of the upper cover 2. A mounting cover 224 extends outward from the bottom edge of the mounting member 22. The first needle 5 and the mounting cover 224 are coaxially arranged.

[0034] When the brewing component is in use, the brewing capsule 3 is placed in the placement cavity 901, and the upper cover 2 is closed to drive the lower end of the first puncture needle 5 to penetrate into the brewing capsule 3. The lower end of the first puncture needle 5 is sleeved with an abutment sleeve 10, which is made of silicone material. The bottom surface of the abutment sleeve 10 is formed with several coaxially arranged abutment rings 1001. When the first puncture needle 5 penetrates into the brewing capsule 3, the abutment ring 1001 is tightly pressed against the top surface of the brewing capsule 3 for sealing, thereby ensuring the sealing reliability between the brewing capsule 3 and the first puncture needle 5.

[0035] A limiting bracket 902 is provided on the upper portion of the capsule holder 9. After the upper cover 2 is connected to the base 1, the top surface of the limiting bracket 902 contacts and cooperates with the bottom surface of the movable cover 21 to ensure that the locking mechanism 8 cooperates with the edge portion of the base 1. The connection between the upper cover 2 and the base 1 is locked by the locking mechanism 8. At this time, the mounting cover 224 is covered on the capsule holder 9 to cover the opening of the placement cavity 901. Hot water enters the first needle 5 through the water pipe 4 to transport water into the brewing capsule 3 to brew coffee powder.

[0036] When water pipe 4 stops supplying water and negative pressure is generated inside water pipe 4 due to cooling or other reasons, the negative pressure inside water pipe 4 drives the check valve body 6 to open, and air outside water pipe 4 is sucked into water pipe 4 through the check valve body 6, maintaining the air pressure inside water pipe 4 stable, effectively preventing coffee liquid or coffee powder in brewing capsule 3 from flowing back into first needle 5 and causing blockage of water pipe 4, thereby ensuring normal use of the coffee machine. Preferably, the check valve body 6 can be any one of a duckbill check valve 6, a diaphragm check valve 6, a spring-loaded check valve 6, or the like.

[0037] The bottom of the capsule holder 9 is connected to a first liquid outlet pipe 903, and the first liquid outlet pipe 903 is provided with a second needle 904 with a pointed end facing upward. The interior of the first needle 5 is hollow, and the second needle 904 penetrates into the brewing capsule 3. The coffee liquid in the brewing capsule 3 is transported to the installation cavity 101 through the second needle 904 and the first liquid outlet pipe 903. The bottom of the base 1 is connected to a second liquid outlet pipe 102, and the second liquid outlet pipe 102 is connected to the installation cavity 101. The bottom inner wall of the installation cavity 101 is inclined toward the first liquid outlet pipe 903 to guide the liquid in the installation cavity 101 to flow to the second liquid outlet pipe 102. The cup can be placed below the second liquid outlet pipe 102 to receive the coffee liquid.

[0038] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
