LIQUID SUPPLY DEVICE AND PERSONAL HYGIENE APPLIANCE CONTAINING IT Russian patent published in 2020 - IPC A46B11/00 

FIELD: devices for liquid supply.

SUBSTANCE: liquid supply device includes a body forming a storage cavity having a total volume including a part with liquid and a part with air. Storage cavity extends along the cavity axis. Capillary element of the device is fluidly connected to the liquid. Proposed device comprises multiple ventilation holes to prevent fluid flow therethrough, allowing air to pass there through. Component in the form of a bushing is installed inside the cavity for storage and contains multiple radial ventilation passages passing between the storage cavity and the primary ventilation passage, which is connected to the environment. Holes for ventilation are arranged and made so that, regardless of inclination and angular orientation of housing relative to gravity vector, at least one of ventilation holes is in spatial communication with air.

EFFECT: liquid supply device with protection against leakage is proposed.
