[0026] The technical solutions in the embodiments of the application will be apparently and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments of the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0027] Reference is made to the drawings attached Figures 1 to 4 A sealing structure of a water-gas separation device of a high-temperature faucet, the water-gas separation device A comprising a water-gas separation device body A1 and a water-gas separation device upper cover A2, the water-gas separation device upper cover A2 can realize the sealing combination of the water-gas separation device body A1 and the water-gas separation device upper cover A2 through welding or sealing by a sealing ring, more specifically, the water-gas separation device upper cover A2 can realize the sealing 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 body A1 can realize the sealing combination of the two through a special-shaped sealing ring p. The sealing structure is applied to the water-gas separation box, which can not only reduce the volume of the water-gas separation box, but also facilitate the arrangement of the structure of the water-gas separation box. Furthermore, compared with the integrated molding method, the water-gas separation device of the application has the advantages of simple structure, small volume, strong sealing reliability and greatly reduced cost.

[0028] Specifically, the water-gas separation device body A1 has a cold water flow channel 1, a hot water cavity 2 and an exhaust flow channel 3 inside, the two ends of the cold water flow channel 1 are respectively communicated with a cold water inlet 11 and a cold water outlet 12, and the two ends of the hot water cavity 2 are respectively communicated with a hot water inlet 21 and a hot water outlet 22, wherein the water passing area of the hot water cavity 2 is greater than the water passing area of the hot water inlet 21, thereby being able to slow down the flow rate of hot water; wherein the hot water cavity 2 is enclosed by two side walls 20, one of which is provided with an exhaust window 23, preferably, the exhaust window 23 is arranged at the top end of the side wall 20, the hot water cavity 2 and the exhaust flow channel 3 are communicated through the exhaust window 23, and the arrangement height of the exhaust window 23 is greater than the hot water inlet 21 and the hot water outlet 22, in a preferred embodiment, the water outlet cross-sectional area of the hot water outlet 22 is greater than the water inlet cross-sectional area of the hot water inlet 21, through this kind of structural design, it can ensure that the hot water flows out from the hot water outlet in time, and the water vapor of the hot water flows into the exhaust flow channel 3 through the exhaust window 23 in time, without causing hot water overflow, so that the two channels can work with each other.

[0029] Furthermore, at least one baffle plate 24 is provided in the hot water chamber 2. This baffle plate can block the direct flow of water at the hot water inlet, reduce the flow rate of the hot water, and prevent the hot water from rushing directly to the outlet. In this way, the flow rate of hot water in the hot water chamber of the water-air separation device is slowed down due to the increased water flow area of ​​the hot water chamber and the obstruction effect of the baffle plate, causing the bubbles to burst. Preferably, the baffle plate 24 is positioned directly opposite the hot water inlet 21, directly using the baffle plate to slow down the flow rate of the hot water, so that the hot water has sufficient buffer time in the hot water chamber for water-air separation. Preferably, the baffle plate 24 is arc-shaped, which reduces the impact force of the hot water and improves the water-air separation effect.

[0030] Furthermore, the aforementioned water-gas separation device is also connected to a water outlet connector 4. A sealing ring is provided between the water outlet connector 4 and the water-gas separation device to ensure the sealing performance of both. The water outlet connector 4 has a cold water channel, a hot water channel, and a gas channel that are connected to the aforementioned cold water outlet 12, hot water outlet 22, and exhaust channel 3. The cold water channel and the gas channel can be arranged in a ring shape around the hot water channel.

[0031] See attached document Figure 5 and attached Figure 6 In another preferred embodiment, the hot water chamber 2 also has a guide plate 25. The guide plate 25 is arranged obliquely downward along the water flow direction, so that the hot water chamber 2 is divided into two stepped chambers. Each of the two stepped chambers is provided with a baffle plate 24. The exhaust window 23 is located in the rear chamber of the two stepped chambers. In this way, the water vapor separation effect of the hot water can be better through segmented water flow buffering, and the hot water can flow out stably from the hot water outlet.

[0032] See attached document Figure 7 In another preferred embodiment, the hot water cavity 2 also has a water storage cavity 2a, where the water vapor mixture will remain. At this time, the density of water vapor in the water vapor mixture in the water storage cavity 2a is much smaller than that of water. Therefore, the water vapor in the water storage cavity 2a will automatically separate into a state where the gas is on top and the water is on the bottom. Then, the water vapor will flow through the exhaust window 23 on the side wall to the exhaust channel 3 and be discharged.

[0033] When the cold water flow channel 1 is turned on, cold water flows into the water outlet joint 4 through the cold water inlet 11, the cold water flow channel 1 and the cold water outlet 12; when the hot water cavity 2 is turned on, hot water (water-gas mixed water) enters the hot water cavity 2 through the hot water inlet 21, the water baffle 24 blocks the straight flow of water to reduce the speed and avoid the straight flow of the hot water outlet, at this time, the water-gas mixed water flow stays in the hot water cavity 2, at this time, the water-gas 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 fact that the density of gas is much smaller than that of water, the water molecules sink, and the gas molecules rise, therefore, the water-gas in the hot water cavity 2 is automatically separated into gas on the top and water on the bottom, the gas flows through the gas exhaust window 23 in the inner side wall to the gas exhaust channel 3, and then is transported to the water outlet joint 4 for discharge, and the water in the hot water cavity 2 flows to the water outlet joint 4 through the hot water outlet 22 for discharge, so as to achieve the purpose of water-gas separation. The water-gas separation device has simple structure and small size, and can be applied to small products.

[0034] In another preferred embodiment, the cold water flow channel 1 and the gas exhaust channel 3 can be directly integrated to form a shared flow channel shared by cold water and gas, thereby integrating the structure and further reducing the size of the water-gas separation device, and the application range is more extensive. Cold water directly flows into the shared flow channel from the cold water inlet, and then is discharged from the water outlet joint 4; when hot water flows into the hot water cavity 2 from the hot water inlet, gas is introduced into the shared flow channel through the gas exhaust window for discharge, and the hot water after separating the gas flows into the water outlet joint 4 from the hot water outlet for use by the user.

[0035] In a specific application, the water-gas separation device can be applied to a high-temperature faucet with a water-gas separation device. Referring to the accompanying drawings Figure 8 and the accompanying drawings Figure 9 , the high-temperature faucet includes a water-gas separation device A and a faucet main body B, a containing space B1 is arranged at the water outlet end of the faucet main body B, the water-gas separation device A is arranged in the containing space B1, and the containing space B1 cooperates with the faucet upper cover B2 to install the water-gas separation device A into the high-temperature faucet; in an embodiment, the control buttons of cold water or hot water and the like can be arranged on the faucet upper cover B2, and the user can directly control the waterway, of course, in other embodiments, a knob can be directly arranged on the faucet main body B to directly control the waterway. In addition, the cold water inlet pipe a1 and the hot water inlet pipe a2 are respectively communicated with the cold water inlet 11 and the hot water inlet 21 in the water-gas separation device A through the faucet main body B, the water-gas separation device is integrated in the faucet main body, the structure is simple, the occupied space is small, the faucet has good water-gas separation effect, the water flow is soft, the water outlet effect is good, and the user can be prevented from being scalded.
