Abstract: A plant full-cycle growth illuminating device includes a control circuit, a first LED component, and a second LED component. The first LED component and the second LED component are respectively connected to the control circuit. The control circuit is configured to obtain a user instruction and respectively control a light output intensity of a first combined spectrum and a light output intensity of a second combined spectrum according to the user instruction, which meet spectral needs of plants in different growth stages of a whole growth circle. Moreover, the first combined spectrum and the second combined spectrum are independent from each other and do not affect each other. The control circuit is simple and low in cost and is flexible to use.

Abstract: A full-spectrum illumination method for plant and a full-spectrum illumination control device for plant are provided. The full-spectrum illumination method for plant includes following steps: illuminating plants through a combination of spectrum during a full life cycle of the plants. The combination of spectrum is a special spectrum combination formed through a plurality of LEDs. Improvement of photosynthesis effect in current plant illumination technology effectively improves effective components and unit time output of the plant, which is suitable for large-scale production and processing extraction of current plant factories.

Abstract: A rotary joint for a lighting fixture includes: a first mounting member having a first housing; a second mounting member having a second housing and a positioning plate; a number of first metal connecting plates fixed to the first mounting member; a number of second metal connecting plates fixed to the second mounting member; and a shaft passing through the first housing, the second housing, the positioning plate, the first metal connecting plates, and the second metal connecting plates. The shaft rotatably connects the first mounting member to the second mounting member.

Abstract: A coffee bean grinder includes a machine body and a burr grinder. The burr grinder is detachably mounted to the machine body, and includes an adjusting mechanism, and a grinding mechanism. The grinding mechanism is connected to the adjusting mechanism, and includes an inner burr that is rotatable about a grinding axis, and an outer burr that surrounds the inner burr, and that is rotatable about the grinding axis relative to the inner burr. The inner burr is movable by the adjusting mechanism along the grinding axis relative to the outer burr so as to adjust a space between the inner and outer burrs.

Abstract: A bean grinding machine includes a base seat, a bean container mounted on the base seat, and a grinding mechanism removably mounted on the base seat. The grinding mechanism includes first and second grinding members which are rotatable relative to and cooperate with each other to define a grinding space for receiving beans introduced from the bean container. Both the first and second grinding members can be removed from the base seat for facilitating cleaning.

Abstract: A coffee machine includes a base, a driving unit, and a water supply unit. The base has a guiding wall, and a spiral guiding groove formed in the guiding wall and winding around a rotational axis. The driving unit includes a transmission gear rotatable about the rotational axis, and formed with a guiding hole that extends radially and outwardly from a center of the transmission gear and that is disposed above said spiral guiding groove. The water supply unit includes a water tube having a guiding section that extends through the guiding hole and the spiral guiding groove, and that is movable along the spiral guiding groove with the guidance of the guiding hole during rotation of the transmission gear about the rotational axis.

Abstract: A device for expelling used capsules of a capsule coffee machine includes a support unit, a receiving seat and a linkage control unit, the support unit has a lower support and an upper support pivotally connected together; the receiving seat is pivotally connected to the lower support of the support unit for receiving a coffee capsule; and the linkage control unit with a pull plate is connected to the upper support and a switch plate pivotally connected to the lower support of the support unit; when the upper support swings upwardly, the pull plates moves upwardly and pulls up the switch plate and the switch plate raises the receiving seat from a receiving position to an overturning position. With the linkage control unit, when the upper support swings it drives the receiving seat with a coffee capsule to expel the coffee capsule out of the receiving seat automatically.

Abstract: An automatic puncture mechanism of a capsule coffee machine, which is used puncture a side wall and a top wall of a coffee capsule, including a support unit with an upper support and a lower support, a linkage unit assembled to the upper support, a first puncture unit assembled to the upper support to perforate the top wall of the coffee capsule driven by the linkage unit, a carrying base assembled to the lower support to hold the coffee capsule, and a second puncture unit assembled to the lower support to perforate the side wall of the coffee capsule driven by the linkage unit. With the linkage unit, when the upper support moves to the lower support, it drives the first puncture unit and the second puncture unit to perforate the top wall and the side wall of the coffee capsule respectively, thus making the coffee machine easier to operate.
