[0020] According to the attached Figures 1 to 6 As shown, the capsule coffee machine with anti-spraying coffee function of the utility model comprises a housing assembly 1, a brewing cup assembly 2, a handle transmission assembly 3, and a brewing cover assembly 4. The brewing cup assembly 2 is mounted at the front end of the housing assembly 1, and the handle transmission assembly 3 is connected to the rear end of the housing assembly 1 in an opening and closing manner and is linked to the brewing cover assembly 4. The brewing cover assembly 4 is driven by the handle transmission assembly 3 and can make a linear reciprocating motion in the housing assembly 1. The housing assembly 1 is provided with a capsule inlet 111 for facilitating the installation of coffee capsules into the brewing cover assembly 4, and the housing assembly 1 is provided with a protective door assembly 5 that can move with the brewing cover assembly 4 to open or close the capsule inlet 111. The protective door assembly 5 is fixed on both sides of the brewing cover assembly 4 and moves linearly with the movement of the brewing cover assembly 4 while telescoping forward and backward on the upper surface of the housing assembly 1.

[0021] Through the structural cooperation of the shell component 1, the brewing cup component 2, the handle transmission component 3, the brewing cover component 4 and the protective door component 5, when the handle transmission component 3 is opened or closed, the brewing cover component 4 is linked to make a linear reciprocating motion back and forth in the shell component 1, thereby driving the protective door component 5, so that the protective door component 5 is compressed to open the capsule inlet 111, which is convenient for placing the coffee capsule, or the protective door component 5 is extended to cover the capsule inlet 111. The structure is simple and the operation is convenient, which effectively avoids coffee splashing accidents during the brewing process and will not spray people, thereby increasing the function of preventing coffee from spraying out and increasing the safety of the machine.

[0022] Reference Figures 1 to 6As shown, in further detail, the protective door assembly 5 includes an upper door 51, a lower door 52 and an elastic member 53 for connection. The upper door 51 is connected to the lower door 52 through the elastic member 53, and the lower door 52 can make reciprocating linear motion between the upper door 51 and the surface of the housing assembly 1. The upper door 51 is installed on the brewing cover assembly 4 and moves forward and backward on the upper surface of the housing assembly 1 as the brewing cover assembly 4 moves, so that the upper door 51 and the lower door 52 are condensed and connected together under the elastic action of the elastic member 53 to open the capsule inlet 111, or driven by the brewing cover assembly 4, the upper door 51 overcomes the elastic force of the elastic member 53 and is fully stretched and connected to the lower door 52 to close the capsule inlet 111.

[0023] Furthermore, a limiting boss 6 is provided on the upper surface of the housing assembly 1 to prevent the lower door 52 from continuing to move forward with the upper door 51 and reaching a fully extended connection with the upper door 51 .

[0024] The handle transmission assembly 3 includes a handle 31, a first fixed rod 32, a first rotating rod 33, a second rotating rod 34, and a third rotating rod 35. One end of the handle 31 is hinged to the housing assembly 1 through a first transmission shaft, the first fixed rod 32 is fixed to the handle 31 and is hinged to the first rotating rod 33 through a second transmission shaft. The first rotating rod 33 is hinged to the second rotating rod 34 and the third rotating rod 35 through a third transmission shaft, the second rotating rod 34 is hinged to the housing assembly 1 through a fourth transmission shaft, and the third rotating rod 35 is fixedly connected to the brewing cover assembly 4.

[0025] That is, when the handle 31 is in the fully opened state, the brewing cover assembly 4 is driven to move backwards by the transmission action of the first fixed rod 32, the first rotating rod 33, the second rotating rod 34 and the third rotating rod 35, so that the upper door 51 and the lower door 52 are pulled together under the elastic action of the elastic member 53, so that the lower door 52 is completely hidden under the upper door 51, so that the upper door 51 and the lower door 52 are condensed and connected together, so as to open the capsule inlet 111, which is convenient for placing the coffee capsule.

[0026] When the handle 31 is closed, the brewing cover assembly 4 is driven forward by the transmission of the first fixed rod 32, the first rotating rod 33, the second rotating rod 34, and the third rotating rod 35, thereby driving the protective door assembly 5 to move forward. When it moves to a certain stroke, the lower door 52 is blocked by the limiting boss 6 to stop moving forward, while the upper door 51 continues to move forward, and the lower door 52 gradually appears. When the handle 31 is completely closed, the upper door 51 moves forward to the end of the stroke, and since the lower door 52 is blocked by the limiting boss 6 to stop moving forward, the lower door 52 is completely exposed. At this time, the upper door 51 and the lower door 52 are fully extended and connected to cover the capsule inlet 111, which plays a role in closing the capsule inlet 111 during the coffee brewing process to prevent coffee and water from leaking and spraying to scald people.

[0027] Reference Figures 1 to 6 As shown, in further detail, the housing assembly 1 includes a shell 11, a water inlet joint 12, and a liquid outlet pipe 13. The shell 11 has a square cavity adapted to install the brewing cup assembly 2 and the brewing cover assembly 4, which is the base of the entire brewing device and plays the role of fixing and supporting other components. One end of the water inlet joint 12 is connected to the brewing cover assembly 4, and the other end of the water inlet joint 12 is connected to the water tank. The liquid outlet pipe 13 is installed on the shell 11 and connected to the brewing assembly. The upper surface of the shell 11 is provided with a limiting boss 6. Strengthening the structural stability, the protective door assembly 5 can smoothly slide forward and backward with the brewing cover assembly 4 to realize the forward and backward telescopic function, which is practical and reliable.

[0028] The brewing cup assembly 2 includes a brewing cup 21, a bayonet 22, and a mounting block 23. A coffee capsule can be installed at the front end of the brewing cup 21, and the rear end of the brewing cup 21 is embedded in the shell assembly 1. The bayonet 22 is fixed to the brewing cup 21 through the mounting block 23.

[0029] And, the brewing cover assembly 4 includes a brewing cover 41, a hook 42, a hook cover 43, a hook elastic member 44, a nozzle 45, a movable member 46, a movable elastic member 47, a pressing block 48, a water inlet pipe 49 and a sealing member 410. The brewing cover 41 is a rectangular structure, and the shell 11 of the housing assembly 1 is provided with a slide groove for the brewing cover 41 to slide forward and backward. The hook elastic member 44 is mounted on the convex column of the hook 42 and fixed to the brewing cover 41 through the hook cover 43. The nozzle 45 is fixed to the brewing cover 41. The movable elastic member 47 is mounted on the convex column of the movable member 46 and fixed to the brewing cover 41 through the pressing block 48. One end of the water inlet pipe 49 is fixed to the brewing cover 41, and the other end of the water inlet pipe 49 is connected to the water inlet joint 12 of the housing assembly 1. The sealing member 410 is arranged in the middle of the inner part of the brewing cover 41. When the handle 31 is closed, the hook 42 is pushed back along the brewing cover 41 by the thrust of the capsule and the brewing cup 21. When the handle 31 is opened, the hook 42 is automatically reset by the hook elastic member 44.

[0030] And, the nozzle 45 is fixed on the brewing cover 41, and the movable elastic member 47 is installed on the boss of the movable member 46 and fixed to the brewing cover 41 through the pressing block 48. The movable member 46 plays the role of bouncing the capsule after the capsule is brewed and making the capsule fall freely.

[0031] In addition, one end of the water inlet pipe 49 is fixed on the brewing cover 41, and the other end of the water inlet pipe 49 is connected to the water inlet connector 12 of the housing assembly 1, and the sealing member 410 is arranged in the middle of the brewing cover 41. The structure is stable and easy to assemble.
