Title:
LIQUID SUPPLY DEVICE AND PERSONAL CARE DEVICE PROVIDED WITH LIQUID SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/101244
Kind Code:
A1
Abstract:
A liquid supply device (100) applied in personal care devices such as a shaver, a hair curler, and a hair iron comprises: a cavity body, wherein a receiving cavity (21) used for storing a liquid is arranged in the cavity body; a liquid outlet hole (22), a liquid feeding hole (24), and an air inlet hole (23) are formed in the cavity body; and the air inlet hole (23) is provided with a waterproof air-permeable film (5). Due to the arrangement of the waterproof air-permeable film (5), air can enter the receiving cavity (21) from the air inlet hole (23) after passing through the waterproof air-permeable film (5). Because the liquid is received in the receiving cavity (21) and the liquid has certain viscosity, the liquid is adhered to a side surface, facing the receiving cavity (21), of the waterproof air-permeable film (5). The waterproof air-permeable film (5) allows air to pass through and does not allow the liquid to pass through; therefore, being blocked by the liquid, the air in the receiving cavity (21) cannot pass through the waterproof air-permeable film (5) and be exhausted from the air inlet hole (23). In this manner, the air compensated into the receiving cavity (21) can facilitate discharge of the liquid from the liquid outlet hole (22), and liquid supply is achieved. By using the structure, it is ensured that the liquid may not be leaked from the air inlet hole (23), and the structure is simple.
