[0031] See also Figure 1 , Figure 2 and Figure 4 The embodiment of the utility model provides an anti-freezing cracking faucet, comprising a faucet body 1, in which a water outlet channel 11, a water inlet channel 12 and a control channel 13 connecting the water outlet channel 11 and the water inlet channel 12 are arranged, a valve core 2 is arranged in the control channel 13, and an anti-freezing cracking component 3 is arranged in the water inlet channel 12;

[0032] The anti-freeze crack assembly 3 includes an anti-freeze crack pipe 31 and a sealing installation cover 34. The anti-freeze crack pipe 31 runs through the center. The end of the anti-freeze crack pipe 31 away from the valve core 2 is radially provided with a plurality of buffer chambers 311. Each buffer chamber 311 is connected to a connecting pipe 32. The other end of the connecting pipe 32 is connected to a constant pressure air bag 33. The connecting pipe 32 passes through the faucet body 1. The sealing installation cover 34 installs the anti-freeze crack pipe 31 in the water inlet channel 12. The anti-freeze crack pipe 31 can be made of elastic material.

[0033] With the above structure, when the temperature drops below zero, the water in the water inlet channel 12 of the faucet body 1 will freeze and expand. Since the anti-freezing crack component 3 is arranged in the water inlet channel 12; the anti-freezing crack component 3 includes an anti-freezing crack pipe 31 and a sealing installation cover 34, the anti-freezing crack pipe 31 runs through the center, and the end of the anti-freezing crack pipe 31 away from the valve core 2 is radially provided with a plurality of buffer chambers 311, each buffer chamber 311 is connected to a connecting pipe 32, and the other end of the connecting pipe 32 is connected to a constant pressure air bag 33, and the connecting pipe 32 passes through the water.
