Specifically, the electric switch 15 is used for controlling the on-off of the electric heating body 4, the electric switch 15 is provided with a mandril 1501, and the mandril 1501 has a retraction state for closing the electric switch 15 and an extension state for opening the electric switch 15; the first pressure comparison cavity 10 is communicated with the water inlet channel; the second pressure ratio cavity 11 is communicated with the heating cavity 3; the rocker 13 is arranged in a rotatable manner, and the first end of the rocker 13 is abutted against the ejector rod 1501; the first pressure ratio cavity 10 and the second pressure ratio cavity 11 are divided by the elastic diaphragm 9, so that when the water pressure in the first pressure ratio cavity 10 is greater than the pressure in the second pressure ratio cavity 11, the elastic diaphragm 9 deforms towards the direction of the second pressure ratio cavity 11; the second end of the rocker 13 is connected to the elastic diaphragm 9, so that when the pressure difference between the water pressure in the first pressure ratio chamber 10 and the water pressure in the second pressure ratio chamber 11 is greater than the predetermined pressure difference, the elastic diaphragm 9 drives the second end of the rocker 13 to move toward the second pressure ratio chamber 11, so that the first end of the rocker 13 pushes the push rod 1501, and the push rod 1501 is switched from the extended state to the retracted state.
According to the above, as shown in fig. 2, when water continuously enters the heating chamber 3 through the water inlet channel and flows out from the heating chamber 3 through the water outlet channel for use by a user, the water in the water inlet channel simultaneously enters the first pressure comparison chamber 10, and the pressure of the water in the first pressure comparison chamber 10 is the same as the pressure of the water in the water inlet channel; the water in the heating chamber 3 simultaneously enters the second pressure ratio chamber 11, which is the same as the pressure of the water in the heating chamber 3 than the pressure of the water in the chamber 11. When the pressure difference between the first pressure ratio and the second pressure ratio between the pressure of the water in the cavity 10 and the pressure of the water in the cavity 11 is greater than the predetermined pressure difference, it indicates that the water pressure of the water in the water inlet channel is greater than the pressure of the water in the heating cavity 3, and it indicates that the flow rate of the water in the water inlet channel is greater, and the water with the greater flow rate needs to be heated by the electric heating body 4 after entering the heating cavity 3.
