Second tap section 6 extends and links firmly with first tap section 1 along the second axis, utilize second tap section 6 to set up control panel 7 along the accommodation space of second axis, make things convenient for the ascending display cover plate at 6 tops of second tap section of control panel 7 to be connected, and be connected with the part in the first tap section 1 downwards, and simultaneously, leave thermal-insulated space between heating unit 3 and control panel 7, thereby form the protection to the electronic components on the control panel 7, reduce heating unit 3 to control panel 7's heat-conduction, thereby restrain control panel 7's temperature rise, guarantee control panel 7's steady operation. In the present invention, the shape of the second faucet section 6 is not particularly limited, and may be linear or curved.

As a preferred embodiment of the present invention, as shown in fig. 2, 5, 6 and 7, a water vapor separator 8 is further provided in the second faucet section 6, the water vapor separator 8 has a hot water inlet 81 capable of communicating with the hot water outlet 31 of the heating unit 3, a water vapor return port 82 communicating with a water vapor receiving port provided in the water tank 2, and a water outlet 83 and a steam exhaust port 84 communicating with the outside, respectively, and the water vapor separator 8 and the control plate 7 are arranged at a spacing in the second axial direction.

In the working process of the instant heating type faucet, one path of the fluid flow path is as shown in fig. 5, the water flow heated by the heating unit 3 flows from the hot water outlet 31 of the heating unit 3 to the hot water inlet 81 of the water-vapor separator 8 to enter the water-vapor separator 8, the water flow in the water-vapor separator 8 can be discharged to the outside through the water outlet 83, and the water vapor in the water-vapor separator 8 can flow to the water vapor receiving opening of the water tank 2 through the water vapor return opening 82 to realize the return of the water vapor.

In the second tap section 6, a water-steam separator 8 arranged in parallel with the control plate 7 along a second axis is arranged, the water-steam separator 8 and the control plate 7 are arranged at intervals in the same radial direction, the water-steam separator 8 is arranged on one side close to the water outlet, the control plate 7 is positioned on the opposite side of the water-steam separator 8 in the same radial direction, and the lower part of the control plate 7 is just opposite to the area connected with the first tap section 1 so as to facilitate the downward wiring of the control plate 7.
