Abstract
A liquid supplying device includes a liquid cartridge and a cartridge mounting unit having a liquid extraction tube. The liquid cartridge includes a liquid chamber, a valve chamber extending in a first direction away from the liquid chamber, first and second air channels, a seal member having a through-hole, a valve element having a closing part, first and second sealing parts and a liquid channel. A third sealing part is provided on the closing part or the liquid extraction tube. The liquid extraction tube entering into the valve chamber through the through-hole contacts the closing part, moving the valve element in a second direction opposite to the first direction from a first state where the closing part closes the through-hole, to a second state where the third sealing part closes the through-hole, and to a third state where the valve chamber is communicated with inside of the liquid extraction tube.
