Liquid container, and electrostatic atomizing apparatus with liquid container
The liquid container according to the present disclosure is a liquid container to be detachably attached to the main body portion of an apparatus. The liquid container includes a container main body, a ventilation hole, and a lid. The container main body includes an upper portion, a bottom portion, and side portions connecting the upper portion and the bottom portion. The container main body is capable of storing a liquid. The ventilation hole penetrates the upper portion of the container main body. The lid is disposed on an inner side of the container main body and, when the liquid is stored in the container main body, is capable of closing or opening the ventilation hole according to a change in a surface of the liquid. The lid includes a fulcrum positioned closer to the side portion of the container main body than to the ventilation hole. The lid is pivotable around the fulcrum with respect to the ventilation hole.
1. A liquid container to be detachably attached to a main body portion of an apparatus, the liquid container comprising:
a container main body including an upper portion, a bottom portion, and side portions connecting the upper portion and the bottom portion, the container main body being capable of storing a liquid;
a ventilation hole penetrating the upper portion of the container main body; and
a lid that is disposed on an inner side of the container main body and that, when the liquid is stored in the container main body, is capable of closing or opening the ventilation hole according to a change in a surface of the liquid;
the lid including a fulcrum positioned closer to the side portion of the container main body than to the ventilation hole,
the lid being pivotable around the fulcrum with respect to the ventilation hole.
2. The liquid container according to claim 1 , wherein
the lid pivots in a direction of closing the ventilation hole as a result of the surface of the liquid rising with respect to the lid, and pivots in a direction of opening the ventilation hole as a result of the surface of the liquid lowering with respect to the lid.
3. The liquid container according to claim 1 , wherein
the lid has a lower specific gravity than the liquid.
4. The liquid container according to claim 1 , wherein
the lid includes an expanded portion on an end of a side of the lid opposite the fulcrum, the expanded portion having a specific gravity that is less than the liquid.
5. The liquid container according to claim 1 , further comprising
a guide for guiding an end on a side of the lid opposite the fulcrum in accordance with pivoting of the lid.
6. The liquid container according to claim 1 , wherein
the ventilation hole is surrounded by a rim including a protruding edge portion that protrudes farther toward the surface of the liquid than an inside surface of the upper portion of the container main body,
the lid includes a recess for accommodating the protruding edge portion when the lid closes the ventilation hole, and includes an extended portion that extends outward from the recess, and
the extended portion includes an abutting surface that is capable of abutting against the inside surface of the upper portion of the container main body when the lid closes the ventilation hole.
7. The liquid container according to claim 1 , wherein
the ventilation hole includes a first ventilation hole and a second ventilation hole that are open in a same direction,
the lid includes a first lid and a second lid,
the first lid is capable of closing the first ventilation hole according to the change in the surface of the liquid when the liquid is stored in the container main body, and
the second lid is capable of closing the second ventilation hole according to the change in the surface of the liquid when the liquid is stored in the container main body.
8. An electrostatic atomizing apparatus, comprising:
the liquid container according to claim 1 ;
a main body portion of the apparatus, the liquid container being detachable from the main body portion; and
an electrostatic atomization unit mounted to the main body portion.
9. The electrostatic atomizing apparatus according to claim 8 , wherein
the ventilation hole includes a first ventilation hole and a second ventilation hole that are open in a same direction,
the lid includes a first lid and a second lid,
the first lid is capable of closing the first ventilation hole according to the change in the surface of the liquid when the liquid is stored in the container main body,
the second lid is capable of closing the second ventilation hole according to the change in the surface of the liquid when the liquid is stored in the container main body,
the apparatus includes an air flow generation unit for generating an air flow that causes air to flow from the first ventilation hole, through the container main body, and toward the second ventilation hole, and
the electrostatic atomization unit is disposed downstream in the air flow with respect to the second ventilation hole.
