The side casing 44 is provided between the base module 1 and the bean feeding module 2 in a substantially upright cylindrical shape and has a connecting portion 441 for connecting the base housing 12. The bean outlet valve mechanism 41 has a connecting part 441 pivotally disposed on the side shell 44 and a connecting rod 413 capable of pushing against the bean outlet valve 411, and a spring 414 having two ends respectively connected to the connecting part 441 and the connecting rod 413. The bean outlet valve 411 has a substantially square plate-shaped valve 411a and a guiding strip 411b connecting the surface of the valve 411a facing the connecting rod 413, the guiding strip 411b is in an inverted U shape and defines a movable slot 411c with the valve 411a, and the valve 411a has a pivoting end 411d close to the torsion spring 412 and a free end 411e opposite to the pivoting end 411 d. The link 413 has a pivot 413a disposed on the side shell 44, a pushing section 413b extending from the pivot 413a toward the bean outlet valve 411 and pushing against the bean outlet valve 411, and a pressing section 413c extending from the pivot 413a toward a direction away from the bean outlet valve 411 and extending out of the side shell 44 and connected to the spring 414. The abutting section 413b has an abutting column 413b1 movably received in the movable slot 411c, an abutting plate 413b2 extending from the pivot 413a toward the bean outlet valve 411 in a bending manner, and a pair of engaging claws 413b3 extending from the abutting plate 413b2 and connecting two ends of the abutting column 413b 1. The bean-collecting box 42 is substantially cylindrical and adapted to collect the roasted coffee beans. The bean outlet channel 43 is a bridge between the bean outlet 33 and the bean collecting box 42, and the bean outlet channel 43 extends from the bean outlet 33 along the same inclined direction as the inclined plate 32, and can guide the coffee beans to leave the heating seat 34 from the bean outlet 33. The spring 414 is used to normally maintain the bean outlet valve mechanism 41 in the closed state.

Referring to fig. 3 to 6, the bean outlet valve mechanism 41 can drive the bean outlet valve 411 to switch between a closed state and an open state, in the closed state, the torsion spring 412 is in a compressed state, the abutting column 413b1 of the abutting section 413b abuts against the free end 411e of the bean outlet valve 411, and a moment generated by a force applied by the abutting column 413b1 to the bean outlet valve 411 and a moment generated by an elastic force applied by the torsion spring 412 to the bean outlet valve 411 can cancel each other, so that the bean outlet valve 411 seals the bean outlet port 33. The user can apply force to the pressing section 413c to pivot the pressing section 413c downward and pivot the abutting section 413b upward, so that the abutting pillar 413b1 moves along the movable slot 411c from a position abutting against the free end 411e of the bean outlet valve 411 to a position abutting against the pivoting end 411d of the bean outlet valve 411, and the bean outlet valve 411 is switched to the open state. In the opened state, since the moment generated by the elastic force applied by the torsion spring 412 to the bean outlet valve 411 cannot be cancelled by the moment generated by the force applied by the abutting pillar 413b1 to the bean outlet valve 411, the elastic restoring force of the torsion spring 412 pushes the bean outlet valve 411, and the bean outlet valve 411 pivots in the direction away from the bean outlet 33 to unseal the bean outlet 33, so that the roasted coffee beans can leave the roasting chamber 31 from the bean outlet 33 along the inclined plate 32 and are guided into the bean collection box 42 through the bean outlet channel 43.

Referring to fig. 3 to 6, the flow of the household coffee bean roasting machine of the present invention is as follows: the user opens the top cover 23 and pours the coffee beans to be roasted from the bean inlet 21 of the bean inlet housing 22 to the heating seat 34, while the bean outlet valve mechanism 41 is in the closed state, preventing the coffee beans from leaving the roasting chamber 31 from the bean outlet 33. The user then operates the controller 39 of the roasting module 3 to activate the air supply device 38 and the heater 37, and blows the hot air heated by the heater 37 toward the inclined plate 32 and into the roasting chamber 31 to roast the coffee beans. After the roasting is completed, the user presses the pressing segment 413c of the connecting rod 413 downward to pivot the pressing segment 413c downward, the bean outlet valve mechanism 41 is switched to the open state, and the roasted coffee beans leave the roasting chamber 31 from the bean outlet 33 along the inclined plate 32 and are guided into the bean collecting box 42 through the bean outlet channel 43. As described above, after the coffee beans are roasted, the user only needs to press the pressing section 413c of the connecting rod 413 downward to allow the coffee beans to enter the bean collecting box 42 to be collected, which is convenient for use.

The inclined plate 32 also functions to blow hot air upward from below the inclined plate 32, and the intensity of the hot air is stronger at a lower position of the inclined plate 32 due to the closer proximity to the air source, so that the coffee beans are blown upward from the lower position of the inclined plate 32 to a higher position of the roasting chamber 31, fall on the higher position of the inclined plate 32, slide to the lower position due to gravity, and are blown upward again, forming a path-stable hot air roasting route, thereby providing the roasting uniformity of the coffee beans.
