Abstract: A container for containing food or liquid is provided. The container includes a body portion, a lid and an attachment. The lid is detachably disposed on the body portion. The attachment is configured to be disposed on the lid or the body portion and includes a magnetic attraction member and a connecting structure. The magnetic attraction member is adapted to be magnetically connected to a mobile electronic device. The connecting structure is disposed between the magnetic attraction member and the container for selectively fixing the magnetic attraction member at a first position or a second position. The connecting structure includes a fastening member, and the fastening member is adapted to be detachably fastened to the body portion or the lid.

Abstract: A container for containing food or liquid is provided. The container includes a body portion, a lid and an attachment. The lid is detachably disposed on the body portion. The attachment includes a magnetic attraction member and a connecting structure. The magnetic attraction member is independent from the lid and adapted to be magnetically connected to a mobile electronic device. The connecting structure is disposed between the magnetic attraction member and the container for selectively fixing the magnetic attraction member at a first position or a second position. At least a portion of the connecting structure is fixed to the container.

Abstract: A handle is mounted on a smart umbrella and contains: a safety device mounted in the handle. The safety device includes a printed circuit board arranged thereon, and the printed circuit board has a bluetooth module and a power module which are fixed on the printed circuit board. The bluetooth module is configured to connect with a bluetooth module of the smart terminal, and when the bluetooth module of the printed circuit board does not connect with the bluetooth module of the smart terminal, the smart terminal sends alert.
