In order to achieve the above purpose, the utility model provides a following technical scheme: an explosion-proof thermostatic faucet comprises a faucet body, wherein the faucet body comprises a hot water inlet, a cold water inlet, a hot water injection cavity, a cold water injection cavity, a thermostatic cavity, a water outlet, a thermostatic opening and a switching opening, the thermostatic chamber is communicated with the opening and closing port, the cold water inlet is communicated with the cold water injection chamber, the hot water inlet is communicated with the hot water injection cavity, the opening and closing port and the thermostatic cavity are respectively provided with a switch connecting groove, the wall clamping positions of the constant temperature port and the cold water injection cavity and the wall clamping position of the cold water injection cavity and the hot water injection cavity are respectively provided with a constant temperature valve connecting groove, the water outlet is communicated with the constant temperature cavity, the cold water injection cavity is communicated with the constant temperature port, the tap body also comprises an explosion-proof part, an explosion-proof cavity is arranged in the explosion-proof part, the explosion-proof cavity is adjacent to the constant-temperature cavity, and the wall thickness of the wall clamping position of the constant-temperature cavity and the explosion-proof cavity is smaller than that of the outer wall of the tap body.

So set up, close explosion-proof thermostatic faucet switch from opening and close the mouth, the delivery port is closed, explosion-proof thermostatic faucet stops out water, thermostatic mouth has the thermostatic valve, the thermostatic valve has the non return function, can prevent the constant temperature intracavity water reflux, the residual water is stayed in the constant temperature intracavity, but when temperature is less than 0 degree centigrade, the residual water condensation of constant temperature intracavity becomes ice, the volume grow, exert the expansive force to all sides, because the double-layered wall department wall thickness of constant temperature chamber and explosion-proof chamber is less than the tap body outer wall thickness, the residual water expands towards this direction icing, so the junction outer wall warp, to explosion-proof portion internal extrusion, because explosion-proof portion memory is in explosion-proof chamber, provide deformation space for the junction outer wall, so the tap body can not burst.

Furthermore, the hot water inlet and the cold water inlet are arranged on an explosion-proof part, and the explosion-proof cavity is communicated with the hot water inlet and the hot water injection cavity.

So set up, when explosion-proof constant temperature tap switch was closed, hot water still had in the explosion-proof intracavity to with the hot water source intercommunication of hot water inlet, the hot water source makes the hot water of explosion-proof intracavity remain the uniform temperature throughout, because explosion-proof chamber is connected with the constant temperature chamber, so can heat the remaining water of constant temperature intracavity indirectly, slow down the remaining temperature drop rate of constant temperature intracavity, reduce the possibility of freezing.

Furthermore, the hot water inlet is positioned on one side of the explosion-proof cavity close to the opening and closing port.

So set up, hot water will follow the one end direct current of explosion-proof chamber and pour into the chamber into to hot water, need not the backward flow and fill up explosion-proof chamber, and it is more gentle to flow.

Furthermore, the constant temperature chamber includes constant temperature water storage chamber and constant temperature goes out the water cavity, the constant temperature water storage chamber with explosion-proof chamber connects, the constant temperature goes out the water cavity and is equipped with the switch spread groove, the constant temperature water storage chamber is equipped with the thermostatic valve spread groove, the delivery port with the constant temperature goes out the water cavity and connects.

So set up, after closing explosion-proof constant temperature tap switch from the opening and closing mouth, the constant temperature goes out the position that the water cavity was equipped with the switch connecting groove and is plugged up, and the water that is located constant temperature in the constant temperature cavity goes out the water cavity and flows out from the delivery port, only leaves the constant temperature water storage intracavity and has residual water, and residual water still less, changes in explosion-proof chamber and keeps warm to it.

Furthermore, the opening and closing port and the switch connecting groove on the constant temperature cavity are coaxial, the shaft is perpendicular to the opening and closing port end face, the constant temperature port and the wall clamping position of the cold water injection cavity hot water injection cavity are coaxial with the constant temperature valve connecting groove at the wall clamping position of the hot water injection cavity and the constant temperature cavity, and the shaft is perpendicular to the constant temperature port end face.

With the arrangement, the thermostatic faucet switch and the thermostatic valve are easier to install, and the operating part connected with the thermostatic faucet switch is more tightly connected with the faucet body after installation, so that the thermostatic faucet switch is more attractive.
