[0014] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0015] Figure 1 to Figure 2 Shown is a schematic structural diagram of the present invention.

[0016] The accompanying drawings are marked as follows: bracket body 1, capsule inlet 1a, coffee outlet 1b, guide slide groove 11, front puncture plate 2, water outlet 2a, puncture sealing ring 21, capsule seat 3, hot water inlet 3a, guide column 3b, capsule sealing ring 31, stainless steel ring 32, rear puncture needle 4, cylinder body 51, cold water inlet and outlet 51a, piston rod 52, piston sealing ring 53, stainless steel shaft 6, stainless steel tension spring 7, card pack silicone 81, card pack silicone pressure plate 82.

[0017] like Figure 1 to Figure 2As shown, the present invention provides a hydraulically driven puncturing coffee brewing stand, which improves the design structure of the pressing mechanically driven puncturing commonly used in traditional capsule coffee machines into a hydraulically driven one. The coffee brewing stand of the present invention includes a stand body 1, a puncturing plate 2 and a capsule seat 3. The stand body 1 is horizontally arranged, and the front end face of the stand body 1 is formed with a coffee outlet 1b, and a capsule inlet 1a for placing coffee capsules is provided at the upper part relatively close to the front end face. A puncturing needle 4 is fixedly installed on the bottom surface of the inner cavity of the capsule seat 3, and the puncturing needle 4 is used to puncture the bottom surface of the inserted coffee capsule. The puncturing plate 2 of the present invention is fixedly installed on the front end of the stand body 1, and a plurality of water outlet holes 2a are designed on its circular plate surface, and the water outlet holes 2a are connected to the coffee outlet 1b. The capsule seat 3 of the present invention can be slidably arranged in the stand body 1 forward and backward, and is located behind the capsule inlet 1a. A one-way hydraulic cylinder powered by water pressure is provided at the rear end of the support body 1. The one-way hydraulic cylinder can rely on hydraulic pressure to drive the capsule seat 3 to move forward, push the inserted coffee capsule to the front piercing plate 2, and pierce the coffee capsule by the piercing plate 2 and the piercing needle 4 under the pressure from the front and back sides. A hot water inlet 3a is provided on the rear side of the capsule seat 3, and hot water provided by a water pump can be injected into the capsule seat 3 through the hot water inlet 3a to brew coffee, and the brewed coffee can eventually flow out through the coffee outlet 1b.

[0018] In the embodiment, the one-way power hydraulic cylinder of the present invention is composed of a cylinder body 51 and a piston rod 52. The cylinder body 51 is hinged at the rear end of the bracket body 1 through a stainless steel shaft 6. In order to prevent the stainless steel shaft 6 from moving, the two ends of the stainless steel shaft 6 are equipped with shaft spring clamps. A cold water inlet and outlet 51a is provided at the bottom of the cylinder body 51, and the cold water inlet and outlet 51a is connected to the water pump. When the water pump is working, cold pressure water can enter the hydraulic cavity of the one-way power hydraulic cylinder through the cold water inlet and outlet 51a, thereby pushing the piston rod 52 to move forward. The capsule seat 3 is fixedly mounted at the front end of the piston rod 52, so that the capsule seat 3 can move synchronously with the piston rod 52. In order to improve the sealing of the inner cavity of the cylinder body, a piston sealing ring 53 is installed at the tail of the piston rod 52.

[0019] The one-way power hydraulic cylinder of the present invention is a one-way power cylinder, and its piston rod 52 cannot be compressed back by hydraulic pressure. Therefore, a pair of stainless steel tension springs 7 are also arranged in the bracket body 1 of the present invention. The stainless steel tension springs 7 can pull the capsule seat 3 back and reset after the water pump stops working and the hydraulic pressure disappears. The front end of the stainless steel tension spring 7 is connected to the capsule seat 3, and the rear end of the stainless steel tension spring 7 is sleeved on the stainless steel shaft 6.

[0020] The front port of the capsule seat 3 of the present invention is provided with a capsule sealing ring 31. The capsule sealing ring 31 can cooperate with the shell of the coffee capsule to prevent the hot water entering the capsule seat 3 from leaking.

[0021] In the embodiment, the outer periphery of the capsule sealing ring 31 is provided with a stainless steel ring 32. The outer periphery of the puncture plate 2 is provided with a puncture sealing ring 21.

[0022] In the embodiment, the left and right sides of the bracket body 1 of the present invention are symmetrically provided with silicone member slots, which are used to clamp the coffee capsules placed therein, limit the position of the coffee capsules, and prevent the coffee capsules from falling off. The silicone member slots are composed of a silicone card pack 81 for clamping the coffee capsules and a silicone card pack pressing plate 82. The silicone card pack 81 is press-fitted and fixed on the bracket body 1 via the silicone card pack pressing plate 82.

[0023] In the embodiment, the capsule seat 3 of the present invention is symmetrically formed with guide posts 3b on its outer periphery, and the bracket body 1 is formed with guide slots 11 for slidingly guiding the guide posts 3b. The arrangement of the guide posts 3b and the guide slots 11 can improve the stability of the capsule seat 3 sliding forward and backward.

[0024] The present invention is horizontally installed in the upper part of the capsule coffee machine, and a water pump and a heating device for providing hot water are also installed in the capsule coffee machine. When the present invention is in use, the coffee capsule can be put in from the capsule inlet 1a, and the silicone card slots arranged on both sides of the bracket body 1 can firmly clamp the coffee capsule so that it does not fall. When the capsule coffee machine is started, the water pump will inject cold water into the hydraulic chamber of the one-way power hydraulic cylinder, and the piston rod 52 of the one-way power hydraulic cylinder drives the capsule seat 3 under the drive of the hydraulic pressure to push the inserted coffee capsule forward onto the puncture plate 2. When the pressure in the hydraulic chamber reaches a certain value, the inserted coffee capsule will be punctured by the puncture plate 2 and the puncture needle 4. At the same time, the water pump will inject hot water into the capsule seat 3 to brew coffee, and the brewed coffee can flow out through the coffee outlet 1b.

[0025] When brewing is completed, the water pump stops working, and the pressure in the hydraulic chamber of the one-way power hydraulic cylinder disappears. At this time, the capsule seat 3 and the piston rod 52 are reset to their original positions by two stainless steel tension springs 7.

[0026] The best embodiment of the present invention has been described, and various changes or modifications made by those skilled in the art will not depart from the scope of the present invention.
