Abstract: A plant cultivation device includes a case, a temperature control module, and a circulation fan. A cultivation room is formed in the case. The temperature control module includes a piezoelectric chip and a heat exchange assembly. The heat exchange assembly includes a heat conduction plate and multiple fins are formed on the heat conduction plate. One surface of the piezoelectric chip is in the cultivation room and attached on the heat conduction plate. The other surface of the piezoelectric chip is outside of the cultivation room. The circulation fan is attached on the heat exchange assembly. A horizontal component of an airflow direction of the circulation fan (300) is in the same direction as a horizontal component of a normal direction of each fin.

Abstract: A plant cultivation device includes a case (100), a temperature control module (200), and a circulation fan (310). A cultivation room (110) is formed in the case (100). The temperature control module (200) includes a piezoelectric chip (210) and a heat exchange assembly (230). The piezoelectric chip (210) includes a first surface (211) outside the cultivation room (110) and a second surface (212) inside the cultivation room (110). The second surface (212) is opposite to the first surface (211). The heat exchange assembly (230) is attached to the second surface (212). The circulation fan (310) is attached to the heat exchange assembly (230) and includes an inlet side (311) for drawing in air and an outlet side (312) for blowing out air, and the inlet side (311) and the outlet side (312) are arranged in the cultivation room (110).

Abstract: A cultivating box comprises a micro control unit (MCU), a memory module, a light adjusting module and a container having a cultivating space for cultivating plants is presented. The memory module records a plurality of parameters respectively corresponding to different growth conditions needed by the plants in different growth stages. The MCU applies corresponding parameters of the plurality of parameters recorded in the memory module to control the light adjusting module in each growth stage of the plants for adjusting the light status of the container, so the environment of the container can satisfy the requirement of the plant in every growth stage.
