Abstract

The invention relates to a vacuum breaking air inlet valve and an electric heating water boiler. The vacuum breaking air inlet valve comprises a valve body. A water inlet is formed in one end of the valve body, the water inlet is used for being connected with a water supply pipeline to flow water into the valve body, and an air inlet is formed in the other end, opposite to the water inlet, of thevalve body. A floating ball and a sealing cover are arranged in the valve body, one end of the sealing cover is connected with the floating ball, and the other end of the sealing cover is fixedly connected to the air inlet. The vacuum breaking air inlet valve further comprises a water blocking mechanism which is arranged at the water inlet and is used for reducing the flow rate of water entering the valve body from the water inlet. According to the vacuum breaking air inlet valve, water is blocked by the water blocking mechanism when the water with large water flow passes through the water inlet, so that when the water flow is too large, a part of water bypasses the floating ball and directly enters the air inlet, so that a subsequent water seal air inlet is avoided, and the problem that the air inlet is damaged due to freezing expansion is solved.

Description

technical field [0001] The invention relates to the technical field of intake valves, in particular to a vacuum breaking intake valve and an electric water boiler. Background technique [0002] Electric water boilers are all provided with a vacuum-breaking intake valve. The existing vacuum-breaking intake valve includes a valve body, and one end of the valve body is provided with a water inlet. The water inlet is used to connect a water supply pipeline to pass water into the valve body. The opposite end of the water inlet is provided with an air inlet, and a floating ball and a sealing cover are arranged in the valve body. One end of the sealing cover is connected with the floating ball, and the other end of the sealing cover is fixedly connected to the air inlet. The state description before boiling water enters the water, such as figure 1 as shown, figure 1 It is a cross-sectional view of the existing vacuum-breaking air intake valve. Before use, keep the air intake in a...
