Liquid container having liquid consumption detecting device

A liquid container, comprising:

• a housing containing therein liquid;
• a liquid supply opening formed in said housing for withdrawing the liquid from said housing;
• a liquid sensor mounted on said housing for detecting a level of the liquid which is variable in accordance with a consumption of the liquid;
• and
• a first partition wall extending in an interior of said housing and defining the interior of said housing into at least two liquid accommodating chambers which communicate with each other, said liquid accommodating chambers comprising:
• an air-communication side liquid accommodating chamber which communicates with ambient air;
• and
• a detection side liquid accommodating chamber in which said liquid sensor is disposed at an upper portion thereof, said detection side liquid accommodating chamber comprising a recessed part formed at a top wall thereof;
• and
• wherein a volume of said air-communication side liquid accommodating chamber is larger than a volume of said detection side liquid accommodating chamber.

• an air-communication side liquid accommodating chamber which communicates with ambient air;
• and
• a detection side liquid accommodating chamber in which said liquid sensor is disposed at an upper portion thereof;
• wherein the volumes of said at least two liquid accommodating chambers decrease from one side wall defining a part of said air-communication side liquid accommodating chamber of said housing to the opposite side wall defining a part of said detection side liquid accommodating chamber of said housing.

A liquid container, comprising:

• a housing containing therein liquid;
• a liquid supply opening formed in said housing for withdrawing the liquid from said housing;
• a liquid sensor mounted on said housing for detecting a level of the liquid which is variable in accordance with a consumption of the liquid, wherein said liquid sensor utilizes vibration phenomena to detect the level of liquid;
• and
• a first partition wail extending in an interior of said housing and defining the interior of said housing into at least two liquid accommodating chambers which communicate with each other, said liquid accommodating chambers comprising:
• an air-communication side liquid accommodating chamber which communicates with ambient air;
• and
• a detection side liquid accommodating chamber in which said liquid sensor is disposed at an upper portion thereof;
• and
• wherein a volume of said air-communication side liquid accommodating chamber is larger than a volume of said detection side liquid accommodating chamber.
