Abstract

A liquid tank for an electrostatic atomizer for liquids is provided, including a receiving space for a liquid and a delimiting wall delimiting the receiving space with respect to the surrounding area. The liquid tank further includes a self-closing valve connecting the liquid tank to the atomizer.

First claim

The invention claimed is:

1. A liquid tank for an electrostatic atomizer for liquids, the liquid tank comprising:
a housing;
a housing cover;
a receiving space for a liquid;
a delimiting wall delimiting the receiving space with respect to a surrounding area within the housing; and
a self-closing valve connecting the liquid tank to the electrostatic atomizer,
wherein the delimiting wall is a flexible, collapsible bag,
wherein the collapsible bag is connected to an outlet channel of the housing cover at a connection region via an elastic deformation connection, and
wherein at least one of the delimiting wall and the housing consists of an insulating material defining an electrostatic shielding, and wherein the insulating material has a dielectric strength of at least 30 kV.

2. The liquid tank as claimed in claim 1 , wherein the insulating material has a wall thickness of at least 1 mm.

3. The liquid tank as claimed in claim 1 , wherein at least one of the delimiting wall and the housing comprises a contact for a reference potential with respect to a high voltage, and
wherein the contact has at least one contact part connected to the electrostatic atomizer.

4. The liquid tank as claimed in claim 3 , wherein the contact comprises a common negative pole or a common ground potential of a high-voltage source and a battery.

5. The liquid tank as claimed in claim 1 , wherein the liquid tank further comprises a detector identifying the liquid tank,
wherein the detector is provided as one of (1) a mechanical coding, for forming an interlocking engagement, (2) an electronic coding in the form of an RFID marking transmitting information about the liquid tank and receiving information about the liquid tank, and (3) an electrical coding forming electrical line routes via contacts.

6. The liquid tank as claimed in claim 1 , wherein the liquid tank further comprises at least one further receiving space for a further liquid and a delimiting wall for delimiting the receiving space with respect to the surrounding area and the first receiving space.

7. The liquid tank as claimed in claim 1 , wherein the liquid tank further comprises at least one filling level indicator indicating a filling level of the liquid in the receiving space.

8. The liquid tank as claimed in claim 1 , wherein the liquid tank further comprises at least one sensor element detecting ambient parameters of the liquid tank and/or the liquid therein, and
wherein the sensor element has a memory element storing the ambient parameters.

9. The liquid tank as claimed in claim 1 , wherein the self-closing valve is one of a diaphragm, a lip valve, a ball valve, and a spring valve.

10. The liquid tank as claimed in claim 1 , wherein the liquid tank further comprises a first mechanical coupling in a surrounding region of the self-closing valve on the housing, and a second mechanical coupling, the geometry of which corresponds to that of the first mechanical coupling so that the second mechanical coupling is adapted to be connected to the first mechanical coupling,
wherein the second mechanical coupling is provided on a portion of the housing facing away from the self-closing valve.

11. The liquid tank as claimed in claim 10 , wherein the first mechanical coupling comprises a bayonet or a rotary bolt mechanism.
