[0028] The following refers to Figures 1-4 Describe a coffee machine brewing device according to some embodiments of the present application.

[0029] The present utility model provides a coffee machine brewing device through the following technical solutions, which includes a brewing base 1, a brewing head 2, and a driving device 3. The brewing head 2 moves up and down in the brewing base 1 under the drive of the driving device 3, enters and cooperates with the brewing device 4 below the brewing base 1 to press, brew, and make coffee in the coffee powder in the brewing device 4, completing the production of coffee.

[0030] Applying the technical solution of this embodiment, the driving device 3 has a mounting seat 30. The mounting seat 30 includes a first bottom plate 31 and a second bottom plate 32 arranged adjacent to each other, and the first bottom plate 31 and the second bottom plate 32 are perpendicularly arranged; the brewing base 1 includes a first side wall 11 and a second side wall 12 arranged adjacent to each other, and the first side wall 11 and the second side wall 12 are perpendicularly arranged. A first connection structure is provided between the first bottom plate 31 and the first side wall 11, and a second connection structure is provided between the second bottom plate 32 and the second side wall 12. Through the first connection structure and the second connection structure, the driving device 3 realizes simultaneous connection and fixation in two perpendicular directions of the first side wall 11 and the second side wall 12 of the brewing base 1, so that the driving device 3 is stably connected and installed on the brewing base 1, improving the stability of the up and down movement of the brewing head 2.

[0031] Specifically, the first connection structure includes a chute 111 provided on the first side wall 11. Along the extending direction of the chute 111, one end close to the second side wall 12 is the entrance 115 of the chute 111, and the end far from the second side wall 12 is the exit 116 of the chute 111. A first limiting member 112 is provided at the exit 116, and the extending direction of the first limiting member 112 is perpendicular to the extending direction of the chute 111. The first bottom plate 31 enters the chute 111 from the entrance 115 and then moves to touch the first limiting member 112 and stays in the chute 111.

[0032] A card slot 113 is also provided at the inlet 115, and the first base plate 31 is provided with a bump 311 that matches the card slot 113; a second limiting member 114 is provided between the chute 111 and the card slot 113, and the extending direction of the second limiting member 114 is consistent with the extending direction of the chute 111; wherein, there are two chutes 111, card slots 113 and second limiting members 114 respectively, and they are arranged in parallel and symmetrically distributed on both sides of the first base plate 31. Therefore, when the first base plate 31 is inserted into the chute 111 from the inlet 115, the chute 111 and the second limiting member 114 limit the movement of the first base plate 31 in the left and right directions, and the card slot 113 and the first limiting member 112 limit the movement of the first base plate 31 in the directions of the inlet 115 and the outlet 116, realizing the connection and fixation of the first base plate 31 to the first side wall 11 in its direction.

[0033] The second connection structure includes a screw seat 121 provided on the second side wall 12 and a screw groove 321 provided on the second base plate 32. Among them, the second side wall 12 is provided with a groove 122, the screw seat 121 is arranged in the groove 122, and the width of the groove 122 is adapted to the width of the second base plate 32, and the depth of the groove 122 is adapted to the thickness of the second base plate 32. Therefore, as the first base plate 31 moves into the chute 111, the second base plate 32 also moves into the groove 122, and the screw groove 321 is fixed to the screw seat 121 with screws. The screwing connection between the screw groove 321 and the screw seat 121 and the cooperation between the second base plate 32 and the groove 122 realize the connection and fixation of the second base plate 32 to the second side wall 12 in its direction.

[0034] In this way, the driving device 3 realizes the connection and fixation with the brewing base 1 in the directions of its two adjacent side walls, greatly improving the installation stability of the driving device 3. At the same time, both the first connection structure and the second connection structure are in the convenient cooperation ways of chutes, card slots and screws, etc., with simple structures, and also improving the convenience and efficiency of installation.

[0035] In addition, a reinforcing rib 312 is provided at the connection between the first base plate 31 and the second base plate 32, which can improve the connection strength between the first base plate 31 and the first side wall 11, and between the second base plate 32 and the second side wall 12.

[0036] In the application of the technical solution of this embodiment, the brewing device 4 switches the corresponding positions with the grinding device and the brewing device of the coffee machine through its own swing to automatically complete the production of coffee. An elastic flap 13 extending downward is provided at the bottom opening of the brewing base 1. When the brewing head 2 finishes brewing and exits from the brewing device 4, and the brewing device 4 swings away from the corresponding position of the brewing device, the elastic flap 13 can scrape off the coffee powder residues attached to the top of the brewing device 4, thereby improving the internal cleanliness of the coffee machine.

[0037] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
