  • Patent number: 8459304
    Abstract: An air intake module of a water feeding apparatus is provided, which includes a body and a valve, and the body includes a water inlet channel and a water outlet channel. An air intake hole runs through the body outward from a joint between the water inlet channel and the water outlet channel, and the valve is disposed at the joint. With the change of a cross-sectional area of the joint, a phenomenon of a high flow rate and a low pressure occurs to force the valve plate open, and air is sucked in mixed with the water flow. When a back pressure of the water flow is larger than an atmospheric pressure outside, the valve plate is forced to close the air intake hole, so as to avoid leakage of the water flow and prevent the air intake hole from being clogged by impurities.
