A fluid transfer device is implemented which has an inlet for receiving a fluid from a subject container or reservoir and an easily controllable outlet to direct the received fluid to a desired location, such as a target container or reservoir. The inlet and outlet may both include conical spouts to which various sized hoses can removably attach to enable directional and maneuverable control for a user. The fluid transfer device includes a base which rests on a surface and provides support for the components above it, including a handle and an operational arm that handles the fluid transfer operations. The fluid transfer device is configured with versatility for adaptability to multiple use cases. For example, the fluid transfer device has a height-adjustable handle to accommodate differently sized containers, a hinged operational arm, and a horizontally-adjustable container rest.

This invention disclosures a liquid storage tank upper cover assembly of a drawing or adding liquid machine and a drawing or adding liquid machine. The liquid storage tank upper cover assembly includes an upper cover, a switching valve foundation disposed at an upper end of the upper cover and a valve cartridge cooperated with the switching valve foundation. The upper cover and the switching valve foundation are a one-piece molded part. The switching valve foundation has a sliding hole, a lower part of the upper cover has a first through-hole and a second through-hole which are spaced apart, and the first through-hole and the second through-hole are both connected to the sliding hole. The switching valve foundation has a third through-hole connected with the sliding hole. The valve cartridge is glidingly provided in the sliding hole.

A filling apparatus (110, 210) for a hermetically sealed bottle (200) is created by means of a dual bottle adapter (210), at least indirectly connected to the bottle (200), for an input of liquid from a storage container (100) provided with a dual container adapter (110) and at least partially filled with liquid, wherein between a liquid exit port (111) of the dual container adapter (110) and a liquid entry port (211) of the dual bottle adapter (210) a sealed-off liquid communication connection is present, and between a gas entry port (112) of the dual container adapter (110) and a gas exit port (212) of the dual bottle adapter (210) a sealed-off gas communication connection is present.

A pumping device includes a barrel, a pump, and a control valve. The barrel has a gas hole. The pump includes a cylinder and a piston movable in the cylinder. The piston partitions the cylinder into a first space and a second space. Air in the first space is able to enter the second space via a one-way mechanism, but not in reverse. The control valve includes a main body and a control element. The main body has a first hole, a second hole, a ventilation hole, an inlet, and an outlet. The first hole and the second hole communicate the gas hole. The inlet communicates the first space, and the outlet communicates the second space. The control element is movable to make the inlet communicate the first hole or the ventilation hole and to make the outlet communicate the ventilation hole or the second hole.
