Problems solved by technology

When the concave surface is broken, there will be disadvantages such as ink ejection becoming unstable in the inkjet recording device
[0005] In the state where the cap covers the ink ejection port, if the internal space of the cap is sealed, the concave surface may be damaged due to the pressure of the internal space.

Abstract

The invention provides a cap and an inkjet recording apparatus. The cap for capping an ink discharge opening of a nozzle head includes a cap main body and an atmosphere communication unit. The cap main body is configured to cap the ink discharge opening. The atmosphere communication unit is configured to couple an internal space of the cap main body to atmosphere in a state where the cap main body caps the ink discharge opening. The cap main body is configured to couple the internal space to the ink discharge opening in a state where the ink discharge opening is capped. The atmosphere communication unit includes a venthole integrally formed to the cap main body, and a tube coupled to the venthole so as to couple the internal space to atmosphere. The tube includes one end coupled to the venthole using press fitting. The cap and the inkjet recording apparatus have simplified structure and reduced manufacturing cost.

Description

technical field [0001] The present invention relates to a cap of a nozzle head and an inkjet recording device. Background technique [0002] Inkjet recording devices are widely used in printers, copiers, multifunction machines, and the like for reasons such as small size, low cost, and silent operation. In an inkjet recording device, ink droplets are ejected from a plurality of nozzles provided in a nozzle head to form an image on a recording medium such as paper. [0003] When the ink evaporates at the ink ejection port at the tip of the nozzle, the ink density becomes high. As a result, the ink ejection port may be clogged. Therefore, the inkjet recording device includes a cap that covers the ink ejection port. [0004] In addition, in the inkjet recording device, the interface of the ink is slightly depressed due to surface tension at the ink ejection port, forming a so-called concave surface. The concave surface is broken by very little pressure. When the concave su...
