An anti-freeze faucet structure contains: a first pipe, a second pipe, a first control valve, a spring, a check valve, and a second control valve. The first pipe includes an orifice, an outlet, an inlet, a stop rim, and an inner screwing section. The second pipe is disposed in the first pipe and includes an aperture and a rotatable knob. The first control valve is joined with the second pipe and includes a through hole, an outer screwing section, a water passage, and a water channel. The spring is mounted in the through hole and is stopped by a limiting rib. The check valve is secured in the through hole and includes a stopping plug and a water stop portion. The second control valve is connected with the water channel to position the spring and the check valve and includes an inlet channel and a close ring.

1. An anti-freeze faucet structure comprising: a first pipe including an orifice defined on a first end thereof, an outlet adjacent to the orifice, an inlet formed on a second end thereof, a stop rim arranged on an inner wall thereof proximate to the inlet, and an inner screwing section arranged therein;a second pipe being hollow and including an aperture defined on one end thereof and communicating therewith, with the second pipe also including a rotatable knob mounted on a top end thereof, wherein the second pipe is disposed in the first pipe;a first control valve joined with the second pipe by using an upper end and including a through hole formed therein and communicating with the aperture, with the first control valve also including an outer screwing section arranged around an outer wall of a lower end thereof to screw with the inner screwing section of the first pipe, wherein the second pipe is rotated to control the first control valve to move upwardly or downwardly; with the first control valve further including a water passage above the outer screwing section and a water channel formed in the lower end thereof adjacent to the outer screwing section;a spring mounted in the through hole of the first control valve and having a first end stopped by a limiting rib in the through hole;a check valve secured in the through hole of the first control valve and pushed by a second end of the spring, with the check valve including a stopping plug fixed on a first end thereof, wherein the stopping plug moves to open an opening of the check valve or to close the water channel of the first control valve, with the check valve also including a water stop portion for starting or stopping water between the aperture and the water passage; wherein when the stopping plug opens the water channel, the water stop portion stops water between the aperture and the water passage; and wherein when the stopping plug closes the water channel, the water stop portion starts the water between the aperture and the water passage; anda second control valve connected with the water channel of the first control valve by a first end to position the spring and the check valve, with the second control valve also including an inlet channel arranged on an outer wall thereof and a close ring disposed on a second end thereof. 2. The anti-freeze faucet structure as claimed in claim 1, wherein the inner screwing section and the outer screwing section are a multiple thread. 3. The anti-freeze faucet structure as claimed in claim 1, wherein the second control valve includes threads formed on the second end thereof to screw with the water channel of the first control valve. 4. The anti-freeze faucet structure as claimed in claim 1, wherein the check valve also includes the opening defined in a second end thereof and extending to an intermediate section thereof, with the check valve also including a stopping plug fixed on a second end thereof, and wherein the opening is closed or is opened in the through hole. 5. The anti-freeze faucet structure as claimed in claim 1, wherein at least one sealing ring is fixed on the stopping plug and the water stop portion of the check valve and between the outer screwing section of the first control valve adjacent to the inlet and the first pipe. 6. The anti-freeze faucet structure as claimed in claim 1 further comprising: a single-direction washer connected with the second pipe between the outlet of the first pipe and the water passage of the first control valve, wherein the water or air flows toward the outlet of the first pipe only. 7. The anti-freeze faucet structure as claimed in claim 6, wherein the single-direction washer is also coupled with the first control valve. 8. The anti-freeze faucet structure as claimed in claim 1, wherein at least one sealing ring is fixed on the stopping plug and the water stop portion of the check valve, between a closing sleeve and the first control valve, and between the outer screwing section of the first control valve adjacent to the inlet and the first pipe. 9. The anti-freeze faucet structure as claimed in claim 1 further comprising a closing sleeve secured in the water channel of the first control valve to stop a second end of the check valve and to close the water channel with the stopping plug. 10. The anti-freeze faucet structure as claimed in claim 9, wherein a sealing ring is fixed between the closing sleeve and the first control valve.
