A liquid ejection head has an ejection module including a pressure chamber and an ejection element configured to eject a liquid in the pressure chamber, a supply channel, a collection channel connected to the supply channel through a pressure chamber, a first pressure adjustment unit, a second pressure adjustment unit, and a circulation pump. A controlled pressure in the first pressure adjustment unit is set higher than a controlled pressure in the second pressure adjustment unit. A pressure reception area of a second flexible member and a second pressing plate in a second pressure control chamber in a case where a second opening is brought into an open state is smaller than a pressure reception area of a first flexible member and a first pressing plate in a first pressure control chamber in a case where a first opening is brought into an open state.

Liquid ejection head

The printing apparatus of the present invention includes: a print head; and a liquid storage container in which a liquid storage chamber that stores a liquid to be supplied to the print head, an atmosphere communication chamber that communicates with the atmosphere, and a communication flow path that causes the liquid storage chamber and the atmosphere communication chamber to communicate are formed integrally. The liquid storage container can take a first posture in which the atmosphere communication chamber is located under the liquid storage chamber in the direction of gravity and a second posture in which the atmosphere communication chamber and the liquid storage chamber are located side by side in the horizontal direction. In the case where the liquid storage container is in the second posture, the liquid injection portion and the communication flow path are located on the upper side of the liquid storage container.

Printing apparatus and liquid storage member

A liquid refill container for refilling a liquid discharge apparatus with liquid includes a liquid storage portion, a pouring portion, and a cap portion. The liquid storage portion is made of a metal and contains liquid. The pouring portion is removeably connected to the liquid storage portion and has an outlet for pouring the liquid. The cap portion is removeably attached to the pouring portion and covers the outlet.

A liquid ejection head includes an element substrate having an energy-generating element configured to generate an energy for ejecting a liquid from an ejection orifice, a support member for supporting the element substrate, the support member including a liquid chamber formed therein to supply the liquid to the ejection orifice, and a damper portion for absorbing vibration of the liquid inside the liquid chamber, the damper portion being flexible. The support member has a through-hole for communicating with the liquid chamber at a position located above the liquid chamber in a vertical direction when the liquid ejection head is in a use orientation. The damper portion has a taper portion that tapers downwardly in the vertical direction and is positioned in such a manner that the tapering portion closes the through-hole, and the damper portion and the support member are attached to each other by a fixing member.

Liquid ejection head and manufacturing method of liquid ejection head

A liquid filling method of filling a liquid storage device including a first tank that stores a liquid to be supplied to an ejection head ejecting the liquid and a second tank that stores the liquid to be supplied to the first tank through a connection port provided in the first tank with the liquid, the method including: injecting the liquid from a liquid storage container into the first tank through a first liquid introduction port provided in the first tank, in a state where a second liquid introduction port provided in the second tank is closed.

Liquid storage device and liquid filling method

A liquid ejection apparatus includes: a recording head that ejects liquid; a sub-tank that is connected to the recording head and temporarily stores the liquid to be supplied to the recording head; a liquid tank that communicates with the sub-tank and is able to be filled with the liquid; a first atmosphere opening unit that is provided in the liquid tank; and a second atmosphere opening unit that is provided in the sub-tank. The second atmosphere opening unit is closable when the liquid tank is filled with the liquid, and the first atmosphere opening unit and the second atmosphere opening unit are able to open the liquid tank and the sub-tank to the atmosphere, respectively, when the sub-tank is filled with the liquid filled in the liquid tank by a hydraulic head pressure.

Liquid ejection apparatus and liquid filling method

A manufacturing method of a liquid supply component in which a liquid supply path is formed between a first constituent component and a second constituent component that are joined with molten resin. The method includes a first step of preparing these constituent components, a second step of causing the constituent components to face each other and forming an orifice portion and a reservoir portion between a mold and a surface of either of the constituent components, and a third step of pouring the molten resin between the constituent components so that it flows into the reservoir portion through the orifice portion.

Manufacturing method of liquid supply component

Peripheral portion of filters includes short-side portions and long-side portions. A first component and a second component each include a first holding section and a second holding section, the long-side portion of the filter being compressively held between the first holding sections, and the short-side portion of the filter being compressively held between the second holding sections. At least one of the first component and the second component includes a wall portion configured to isolate the long-side portion and the resin from each other. The short-side portion and the resin are in contact with each other.

There are provided a liquid ejecting device that can efficiently supply liquid inside a liquid containing unit with a simple structure and the liquid containing unit. The present invention is the liquid ejecting device which includes a liquid container, a head that is provided on a carriage and has a liquid containing unit capable of storing liquid thereinside and a liquid ejecting unit, and a flexible member that connects the liquid container to the liquid containing unit and supplies the liquid stored inside the liquid container to the liquid containing unit. A holding member is arranged inside the liquid containing unit to hold the liquid, and the shortest distance between a supply port opened to an inside of the liquid containing unit and the holding member is 0.1 mm or more and 5.0 mm or less.

Liquid ejecting device and head

A downsized liquid ejecting device is provided. To do so, the liquid ejecting device includes a liquid container, a head provided on a carriage and having a liquid containing unit capable of storing liquid thereinside, and a liquid ejecting unit ejecting liquid, and a flexible member that connects between the liquid container and the liquid containing unit and supplies the liquid stored inside the liquid container to the liquid containing unit, and a concave portion is formed on an outer wall surface of the liquid containing unit, and a projected portion that is inserted to the flexible member is formed inside the concave portion.
