[0026] Further, at least one water baffle 24 is arranged in the hot water cavity 2, which can block the direct flow of hot water at the hot water inlet, reduce the flow rate of hot water, and avoid the direct outflow of hot water, so that the flow rate of hot water in the hot water cavity of the water-air separation device is slowed down and the water bubble is broken due to the increase of the water area of the hot water cavity and the blocking effect of the water baffle. Preferably, the water baffle 24 is arranged opposite to the position of the hot water inlet 21, directly using the water baffle to slow down the flow rate of hot water, so that the hot water has enough buffer time for water-air separation in the hot water cavity; preferably, the water baffle 24 is in an arc shape, which reduces the impact force of hot water and has better water-air separation effect.

[0027] Further, the water-air separation device is further connected with a water outlet joint 4, and a sealing ring is arranged between the water outlet joint 4 and the water-air separation device to ensure the sealing property of the two, wherein the water outlet joint 4 has a cold water channel, a hot water channel and a gas channel which are communicated with the cold water outlet 12, the hot water outlet 22 and the exhaust flow channel 3 respectively, and the cold water channel and the gas channel can be arranged around the hot water channel to form an annular shape.

[0028] Reference is made to the drawings attached Figure 4 and the drawingsFigure 5 In another preferred embodiment, the hot water cavity 2 further has a flow guide plate 25, which is arranged obliquely downward along the water flow direction, so that the hot water cavity 2 is divided into two stepped cavities, both of which are provided with water baffle 24, and the exhaust window 23 is located in the rear cavity of the two stepped cavities, so that the water vapor separation effect of hot water is better through the segmented water flow buffering, and the hot water can be stably discharged from the hot water outlet.

[0029] Referring to the drawings Figure 6 In another preferred embodiment, the hot water cavity 2 further has a water storage cavity 2a, and the water vapor mixed water flow stays in the water storage cavity 2a, at this time, the density of water vapor in the water vapor mixed water flow in the water storage cavity 2a is much smaller than that of water, so the water vapor in the water storage cavity 2a will automatically separate into gas on the top and water on the bottom, and then the water vapor will flow through the exhaust window 23 of the side wall into the exhaust flow channel 3 and be discharged.

[0030] When the cold water flow channel 1 is conducted, the cold water flows into the water outlet connector 4 through the cold water inlet 11, the cold water flow channel 1 and the cold water outlet 12, and the cold water flow channel is conducted; when the hot water cavity 2 is conducted, the hot water (water vapor mixed water) enters the hot water cavity 2 through the hot water inlet 21, and the water baffle 24 will block the straight flow to reduce the speed and avoid the straight flow to the hot water outlet, at this time, the water vapor mixed water flow stays in the hot water cavity 2, at this time, the water vapor mixed water flow in the hot water cavity 2 is automatically separated into gas on the top and water on the bottom due to the density of gas is much smaller than that of water, so the water molecules sink and the gas molecules rise, therefore, the water vapor in the hot water cavity 2 will automatically separate into gas on the top and water on the bottom, the gas will flow through the exhaust window 23 of the inner side wall into the exhaust flow channel 3, and then be transported to the water outlet connector 4 for discharge, and the water in the hot water cavity 2 will flow to the water outlet connector 4 through the hot water outlet 22 for discharge, so as to achieve the purpose of water vapor separation. The water vapor separation device of the present application has simple structure and small size, and can be applied to small products.

[0031] In another preferred embodiment, the above-mentioned cold water flow channel 1 and exhaust flow channel 3 can be directly integrated to form a common flow channel shared by cold water and gas, so as to integrate the structure and further reduce the size of the water vapor separation device, and the application range is more extensive. The cold water directly flows into the common flow channel from the cold water inlet, and then is discharged from the water outlet connector 4; when the hot water flows into the hot water cavity 2 from the hot water inlet, the gas is introduced into the common flow channel through the exhaust window and discharged, and the hot water after separating the gas flows into the water outlet connector 4 from the hot water outlet for use by the user.

[0032] In another preferred embodiment, the water-gas separation device A is composed of a water-gas separation device main body A1 and a water-gas separation device upper cover A2, the water-gas separation device upper cover A2 can realize the sealed combination of the water-gas separation device main body A1 and the water-gas separation device upper cover A2 through welding or sealing with a sealing ring, more specifically, the water-gas separation device upper cover A2 can realize the sealed combination of the two through ultrasonic welding or hot plate welding, or the water-gas separation device upper cover A2 and the water-gas separation device main body A1 can realize the sealed combination of the two through a special-shaped sealing ring.
