A liquid storage apparatus including: a stirring portion including a storage unit configured to store liquid and a drive unit configured to drive the storage unit; and a storage portion configured to store the stirring portion, the storage portion being opened and closed by an opening and closing member, wherein in a case where a stop condition relating to a state of the opening and closing member is satisfied, rotation of the storage unit by the drive unit is stopped.

A liquid agitating apparatus includes a first storing container configured to store a first liquid, a first agitating mechanism configured to agitate the first liquid in the first storing container by causing the first storing container to undergo a first movement, a second storing container configured to store a second liquid different from the first liquid; and a second agitating mechanism configured to agitate the second liquid in the second storing container by causing the second storing container to undergo a second movement different from the first movement.

A liquid stirring apparatus comprises storage means for storing a liquid; and driving means for performing a rotation operation of rotating the storage unit. The rotation operation includes a stop operation of stopping rotation of the storage means at a plurality of stop positions. The plurality of stop positions include a first stop position at which a stop time is a first time, and a second stop position at which the stop time is a second time different from the first time.

A DTF continuous ink supply device with a built-in stirring function, comprising a box body and a box cover, the box body and the box cover are installed and connected in a detachable up-and-down structure, ink bottles are installed in the box body, the ink bottles are arranged in six groups, wherein two of the groups are white ink bottles, each white ink bottle is provided with a stirring paddle, a motor is installed on an internal top wall of each white ink bottle, a rotating shaft of the stirring paddle is connected to an output end of the motor. The invention relates to the technical field of ink supply devices.

A liquid storage apparatus includes a storage unit configured to extractably store a liquid container with flexibility, a path forming unit connected to the liquid container stored in the storage unit and configured to form a path configured to flow a liquid out of the liquid container, and a pressing unit configured to press the liquid container stored in the storage unit. The pressing unit is configured to perform a stirring operation of stirring the liquid stored in the liquid container by repeating pressing of the liquid container and reducing of the pressing, and a regulating operation of maintaining a state in which the liquid container is pressed and regulating extraction of the liquid container from the storage unit.

According to an example, a mixing device comprises a first chamber including a solute addition member and a first mixer, a second chamber including a second mixer, a printing fluid pump, and a controller operatively connected to the solute addition member, the pump, the first mixer, and the second mixer. The controller is to control the pump to move printing fluid towards the printing fluid tank based on a printing fluid density level in the printing fluid tank, to control the solute addition member to add solids based on the printing fluid density level, and to control the first mixer and the second mixer to mix the added solids with the printing fluid moved by the pump.

In an inkjet recording device that uses a pigment-based ink, an ink device is provided in which ink sticking in an ink path and the precipitation of pigment components in an ink container, which occur when printing is not performed over a long period, can be suppressed, and the pigment-based ink can be jetted in a short time at the restart of the printing. The inkjet recording device uses a pigment-based ink. A control section 7 executes a printing mode performing a printing operation and a rest mode not performing the printing operation. In the rest mode, the control section 7 forcibly performs the stirring of a pigment-based ink 68A in an ink container 31 and the circulation of the ink in an ink circulation path not including a printing head (S300) or the circulation of the ink in an ink circulation path including the printing head (S400). Accordingly, it is possible to suppress ink sticking in the ink circulation path and the precipitation of pigment components in an ink container, which occur when printing is not performed over a long period, and to jet the pigment-based ink in a short time at the restart of the printing.

A stirring apparatus includes a storage portion configured to store a container, a stirring unit configured to perform a stirring operation for the container stored in the storage portion such that a liquid contained in the container is stirred, a regulating unit whose state changes between a regulating state in which extraction of the container from the storage portion is regulated and a regulation cancel state, and a control unit.

The control unit interrupts the stirring operation upon determining that the state of the regulating unit changes from the regulating state to the regulation cancel state during the stirring operation, and resumes the stirring operation upon determining that the state of the regulating unit changes from the regulation cancel state to the regulating state during the interruption of the stirring operation.

A liquid supply apparatus includes a liquid container including a containing part having flexibility, and a connecting part provided at an end portion of the containing part, a channel connected to the connecting part and configured to flow a liquid out of the liquid container, a rotation unit configured to rotate the containing part with respect to the connecting part, a regulating unit configured to regulate displacement of the connecting part in a direction crossing a connection direction between the connecting part and the channel.

A recording apparatus includes a discharge head configured to discharge liquid, a liquid container configured to accommodate the liquid to be supplied to the discharge head, a flow path configured to connect the discharge head and the liquid container, a valve configured to open and close the flow path, and an agitation unit configured to agitate the liquid in the liquid container, wherein, in a case where the agitation unit performs agitation during a recording operation, the valve is closed.
