[0029] Anti-arc block 712 is arranged in the spin buckle groove. Spin buckle protrusion 91 is provided with pit 911 corresponding to anti-arc block 712, so when it is necessary to spin open brewing cover 7 from brewing seat 9, the matching resistance of anti-arc block 712 and pit 911 needs to be overcome to prevent unexpected separation of the two.
[0030] Drawer handle 12 is installed on the outside of brewing cover 7.
[0031] Drawer handle 12 includes handle plate, first mounting part, and the first mounting part includes first fixed plate 123 and second limiting arc 122. The first fixed plate is lapped on the surface edge of brewing cover 7, and the second limiting arc is embedded in the third mounting groove 72 of brewing cover 7. A recess 73 is arranged on the surface edge of brewing cover 7, and a sunken block is designed on the first fixed plate 123 accordingly, so as to facilitate positioning and installation of the two more firmly and prevent loosening. The drawer handle 12 and the brewing cover 7 are tightly installed by screws at the recess 73.
[0032] Drawer panel 13 is installed on the outside of brewing seat 9. The outside of brewing seat 9 is provided with a flange 92, which is embedded in the fourth mounting groove 132.

The hydraulic chamber is equipped with a spout 6 and a first return spring 16. The brewing chamber is formed by the closing of the brewing cover and the brewing seat. The hydraulic chamber is used to receive liquid so that the spout can be pushed out of the hydraulic chamber and pass through the first through hole into the interior of the brewing chamber.
[0035] The outlet pipe 1 connects to the water circuit of the coffee machine. Water from the water tank enters the electric heater for heating and then flows through the pipe into the hydraulic chamber. The spout 6 is threadedly connected to the pressure relief valve seat 4, and a sealing ring is provided on the connection end face for sealing. The first outer wall of the pressure relief valve seat 4 is provided with an annular groove and an internal sealing ring, so that the pressure relief valve seat 4 and the inner wall of the outlet pipe 1 form a seal. The spout seat 2 has a positioning step. When the pressure relief valve seat 4 moves downward under the action of the water pressure above it until the first outer wall touches the positioning step of the spout seat 2, the spout 6 reaches the downward extension stop position. At this time, the water pressure further increases, and its pressure pushes open the mushroom head 5. The hot water in the hydraulic chamber enters the valve chamber of the pressure relief valve seat 4 through the valve port, and then enters the brewing chamber through the spout. When the water pressure above the pressure relief valve seat 4 decreases, the first return spring 16 pushes it upward, and the spout retracts.

A recessed cavity 82 is provided on the outer side of the capsule holder 8, and a second through hole 821 is provided at the edge of the recessed cavity. The base of the piercing needle is mounted on the recessed cavity 82, and the needle foot of the piercing needle passes through the second through hole and extends into the inner cavity of the capsule holder 8. A water injection hole 83 is provided at the center of the bottom of the recessed cavity 82, and three smaller drain holes 84 are provided around the water injection hole 83. The base of the piercing needle is provided with a small hole corresponding to the water injection hole 83 and the drain holes 84. The small hole at the base of the piercing needle overlaps with the water injection hole 83 and the drain holes 84. Hot water flowing from the spout passes through the water injection hole 83, the drain holes 84, and the small hole of the piercing needle, and enters the inner cavity of the capsule holder 8 and the coffee capsule, thereby extracting coffee liquid.
[0037] The capsule seat 8 is fixed on the brewing cover 7 by the mounting column 81 in screw, the capsule seat 8 is inverted, and the opening is located at the bottom, the edge groove is arranged on the opening edge of the capsule seat 8, the O-shaped sealing ring is arranged in the groove, the capsule pressing plate 11 is arranged below the capsule seat 8, the trapezoidal protruding block that passes through is uniformly arranged on the upper surface of the capsule pressing plate 11 and is used to tear the surface of the coffee capsule. The convex tube 90 is arranged on the bottom of the brewing seat 9, the bottom surface of the capsule pressing plate 11 is provided with three screw columns 111, the screw column is inserted into the convex tube 90, and the brewing seat 9 is fixed in screw.
[0038] The drawer cavity is arranged on the machine body, and the drawer cavity is used to accommodate the brewing cover 7 and the brewing seat 8. The drawer handle 12 is mounted on the outer side of the brewing cover 7. Therefore, when the extraction of the coffee liquid is finished, the water outlet nozzle retreats into the hydraulic cavity, and the brewing cover 7 and the brewing seat 8 can be taken out from the drawer by holding the drawer handle 12, and a new capsule is replaced.
[0039] The embodiments of the utility model are described in detail in combination with the drawings, but the utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the utility model, and still fall within the protection scope of the utility model.
