, as depicted in figs. 1 and 2, should the electric hot water with water-proof function in a preferred embodiment of the present utility model
There is tap switch valve, electric switch 15, first pressure to compare chamber 10, second pressure comparison chamber 11, seesaw 13 and elastic diaphragm
9.Specifically, electric switch 15 is used for the power on/off for controlling electric heating body 4, and electric switch 15 has a push rod 1501, push rod 1501
With the retracted state for making the closure of electric switch 15 and the stretching state for disconnecting electric switch 15；First pressure compares chamber 10 with entering
Aquaporin is connected；Second pressure compares chamber 11 and connected with heating chamber 3；Seesaw 13 rotatably set, the first end of seesaw 13 with
Push rod 1501 offsets；First pressure comparison chamber 10 compares chamber 11 with second pressure and split by elastic diaphragm 9, with when first pressure ratio
When being more than the pressure in second pressure comparison chamber 11 to the hydraulic pressure in chamber 10, elastic diaphragm 9 compares the side of chamber 11 towards second pressure
To deformation；Second end of seesaw 13 is connected with elastic diaphragm 9, to compare the hydraulic pressure and second pressure ratio in chamber 10 when first pressure
When being more than predetermined pressure difference to the pressure differential of the hydraulic pressure in chamber 11, elastic diaphragm 9 drives the second end of seesaw 13 towards the second pressure
Power compares chamber 11 and moved, so that the first end pushing and pressing push rod 1501 of seesaw 13, push rod 1501 switches to retraction shape by stretching state
State.
Understood according to above-mentioned, as shown in Fig. 2 when water constantly by intake tunnel into heating chamber 3, and passed through from heating chamber 3
Exhalant canal outflow is crossed for user in use, the water in intake tunnel is simultaneously into first pressure comparison chamber 10, first pressure
The pressure that power compares the water in chamber 10 is identical with the pressure of the water in intake tunnel；Water in heating chamber 3 enters second and pressed simultaneously
Power compares chamber 11, and the pressure that the second pressure compares the water in chamber 11 is identical with the pressure of the water in heating chamber 3.When the first pressure
The pressure difference value that the pressure of water in power comparison chamber 10 compares the pressure of the water in chamber 11 with second pressure is more than predetermined pressure difference
During value, illustrate that the hydraulic pressure of water in intake tunnel is larger with respect to the pressure of the water in heating chamber 3, while illustrating in intake tunnel
The flow of water is larger, and the water of the larger flow needs to be heated by electric heating body 4 after entering heating chamber 3.Now, in pressure
In the presence of difference, elastic diaphragm 9 drive seesaw 13 the second end towards second pressure compare chamber 11 move, seesaw 13 rotate with
The first end of seesaw 13 is set to push against the push rod 1501 of electric switch 15, so that electric switch 15 is closed, so that electric heating body 4 is logical
Electricity, electric heating body 4 provides heating preparation for that will enter in heating chamber 3 but remain the water being in intake tunnel.When the first pressure
The pressure difference value that the pressure of water in power comparison chamber 10 compares the pressure of the water in chamber 11 with second pressure is less than predetermined pressure difference
During value, illustrate that the pressure of water in intake tunnel is smaller with respect to the pressure of the water in heating chamber 3, while illustrating in intake tunnel
The flow of water is smaller, if should enter heating chamber 3 compared with the water of low discharge, electric heating body 4 is still in electrified regulation state, electrical heating
The easy dry combustion method of body 4, however, now, because pressure difference value is less than predetermined pressure difference, elastic diaphragm 9 drives the second of seesaw 13
End can not still make seesaw 13 first end push against push rod 1501 so that push rod 1501 be in retracted state and close electric switch 15,
That is, electric heating body 4 is now powered off, so that effectively prevent because the flow of the water in intake tunnel is smaller, should be compared with low discharge
Water enter heating chamber 3 after electric heating body 4 make the generation of the dry-fire condition of electric heating body 4 still in heated condition.
The utility model is according to the pressure of water in intake tunnel and the difference of the pressure of the water in heating chamber 3 and electric switch 15
Power on/off be associated so that when the water-carrying capacity of intake tunnel is larger, electric heating body 4 is opened in advance and thinks that heating water does standard
It is standby；And when the current of intake tunnel are smaller, electric heating body 4 is closed in advance to make electrical heating when preventing that the reclaimed water of heating chamber 3 is less
The dry combustion method of body 4, so as to effectively increase the life-span of electric heating body 4 and the electric hot water tap with water-proof function.
It should be noted that：Above-mentioned predetermined pressure difference need to be according to the power setting of electric heating body 4, that is to say, that when
The power of electric heating body 4 is larger, and predetermined pressure difference needs to set smaller value, so that the sensitivity increase of electric switch 15, electricity
The sensitivity of the power on/off of calandria 4 also increases, so as to more can effectively prevent the dry combustion method of electric heating body 4；When the work(of electric heating body 4
Rate is smaller, and predetermined pressure difference needs to set higher value, so that the action of electric switch 15 is slower, the break-make of electric heating body 4
The frequency of electricity diminishes, so that the number of transitions of power on/off is reduced, and because the power of electric heating body 4 is smaller, caloric value is small,
Electric heating element will not be made not reach the degree of dry combustion method.
To prevent from entering the Room of heating chamber 3 under water compared with low discharge, as shown in figure 1, preferred real at one of the present utility model
Apply in example, the electric hot water tap with water-proof function also includes pressure-control valve, pressure-control valve includes being arranged in heating chamber 3
Control valve element 7 and control spring 8, control valve element 7 be located at the position relative with the delivery port of intake tunnel, control spring 8 use
In the delivery port for making control valve element 7 block intake tunnel, when the water in intake tunnel exceedes scheduled pressure value, to control valve element
7 are opened, and the water in intake tunnel is flowed into heating chamber 3.
The purpose for setting pressure-control valve has two：On the one hand, the hydraulic pressure for entering heating chamber 3 is limited, that is, limits and enters tool
There is the pressure of the water of the electric hot water tap of water-proof function, so that the electric hot water tap with water-proof function is according to hydraulic pressure control water
Circulation, that is to say, that the electric hot water tap of the present utility model with water-proof function when water pressure be less than pressure-control valve
During the pressure limited, water will not be allowed to flow through；On the other hand, facilitate first pressure to compare chamber 10 and compare the shape of chamber 11 with second pressure
Into pressure differential, so that convenient control electric switch 15.
It should be noted that：Described scheduled pressure value is set according to described predetermined pressure difference, obtains pre- calculating
After level pressure force value, it can calculate and choose the control spring 8 of certain coefficient of elasticity to meet when more than predetermined pressure, in intake tunnel
Water can open control valve element 7.
