Embodiment
It is below in conjunction with the accompanying drawings and specific real to make those skilled in the art be better understood from the technical solution of the utility model
Mode is applied to elaborate to the utility model.
As depicted in figs. 1 and 2, embodiment of the present utility model provides a kind of electric heating fire hose with creepage protection function
Head, should with creepage protection function electric hot water tap have metal shell 1, be formed at into the heating chamber 3 inside water housing 1,
Intake tunnel, exhalant canal, switch valve, electric switch 15, first pressure compare chamber 10, second pressure compare chamber 11, seesaw 13 with
And elastic diaphragm 9.Specifically, it is provided with electric heating body 4 in heating chamber 3；Intake tunnel is connected with heating chamber 3 thinks heating chamber 3
Supply water；Exhalant canal is connected with heating chamber 3, and the water in heating chamber 3 flows out from exhalant canal；Switch valve is used to control intake tunnel
Break-make；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, and push rod 1501 has
The stretching state for having the retracted state for closing electric switch 15 and 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, to work as first pressure
When comparing the pressure that the hydraulic pressure in chamber 10 is more than in second pressure comparison chamber 11, elastic diaphragm 9 compares chamber 11 towards second pressure
Direction distortion；Second end of seesaw 13 is connected with elastic diaphragm 9, to compare the hydraulic pressure and second pressure in chamber 10 when first pressure
When the pressure differential for comparing the hydraulic pressure in chamber 11 is more than predetermined pressure difference, elastic diaphragm 9 drives the second end of seesaw 13 towards second
Pressure ratio is moved to chamber 11, so that the first end pushing and pressing push rod 1501 of seesaw 13, push rod 1501 switches to retraction 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 creepage protection 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.
Because metal shell 1 leaks electricity, the utility model is also additionally arranged earth leakage protective component, and the earth leakage protective component is used to make
Metal shell 1 is grounded, so as to improve the security of electric hot water tap.
