[0001] This utility model relates to the field of antifreeze faucet technology, specifically an antifreeze faucet. Background Technology

[0002] In cold regions, preventing faucets from freezing is a critical concern. Traditional faucets are prone to damage and even pipe cracking in low temperatures because water easily freezes inside the pipes and faucet, leading to water waste and increased repair costs. Existing antifreeze measures are often simple, such as wrapping the faucet and parts of the pipes with basic insulation, but these methods are limited in effectiveness under extremely cold conditions and fail to effectively prevent water from freezing inside the pipes.

[0003] Existing technology further prevents freezing by injecting air into the pipe, but this usually involves adding an air injection hole to the faucet pipe. For faucets that need to be used frequently, the frequent manual air injection causes some inconvenience. Utility Model Content

The air injection component includes a connecting water pipe 3 installed on the faucet body 1, a pressure cylinder 4 installed on the connecting water pipe 3, and an air vent valve 5 installed on the connecting water pipe 3. The air vent valve 5 is located inside the pressure cylinder 4. A pressure plate 6 is provided inside the pressure cylinder 4, and the side of the pressure plate 6 is in contact with the inner wall of the pressure cylinder 4. A one-way valve 7 is installed on the cylinder wall of the pressure cylinder 4. The one-way valve 7 is configured to allow air to flow only from the outside of the pressure cylinder 4 to its interior, so as to achieve a specific one-way airflow function.

[0026] The exhaust valve 5 is preferably a single-port exhaust valve, which can achieve unidirectional exhaust while also allowing gas to flow in from the outside to the inside.

[0027] The gas injection assembly also includes a pressure rod 19, which is mounted on the pressure plate 6. One end of the pressure rod 19 passes through the pressure cylinder 4 and extends to the top of the pressure cylinder 4.

[0030] Working principle:

[0031] Installation and Initial Setup

[0032] Install the faucet body 1 into the water pipe system in a conventional manner. Connect the connecting water pipe 3 to the faucet body 1, and install the air injection components such as the pressure cylinder 4 and the air release valve 5 in sequence. Install the pressure plate 6 and the one-way valve 7 inside the pressure cylinder 4. Pass the pressure rod 19 through the top of the pressure cylinder 4 and connect it to the worm gear 10. Install the worm 9 on the top plate connecting plate 8, ensuring smooth meshing of the worm gear 10 and the worm 9. Connect the detection box 12 to the connecting water pipe 3. Install the bracket 13, the top rod 14, the pressure plate 15, the spring 16, and the contact switch 18 inside the detection box 12, and connect the contact switch 18 to the microcontroller 17. The drive motor 11 is installed on the top of the pressure cylinder 4 and connected to the worm gear 9 for transmission. This completes the assembly and wiring connection of the entire antifreeze faucet, ensuring that all components are securely installed and leak-free.

[0033] Workflow

[0034] During normal use, the faucet flows water normally like a regular faucet. After the water is discharged, the faucet is closed, causing a pressure change in the connecting water pipe 3. This pressure change is transmitted to the detection box 12, and the pressure plate 15 moves the push rod 14 under pressure. When the pressure reaches a certain value, the push rod 14 triggers the contact switch 18, which sends a signal to the microcontroller 17.

[0035] After receiving the signal, the microcontroller 17 starts the air injection component according to the preset program and automatically completes the pressurization operation. The drive motor 11 is started, which in turn drives the worm gear 9, which drives the worm wheel 10 to rotate, thereby moving the pressure rod 19 downward. This forces the air inside the pressure cylinder 4 into the connecting water pipe 3 through the exhaust valve 5, increasing the air pressure in the connecting water pipe 3 to prevent ice from forming inside the faucet.

[0036] When water is released again, the tap is turned on, causing a pressure change in the connecting water pipe 3. This pressure change is transmitted to the detection box 12, and the pressure plate 15 is reset by the action of the spring 16, no longer triggering the contact switch 18. The contact switch 18 sends a signal to the microcontroller 17. Upon receiving the signal, the microcontroller 17 starts the air injection component according to the preset program, reversing the start of the drive motor 11, thereby moving the pressure plate 6 to its highest position. During this process, air enters the pressure cylinder 4 through the one-way valve 7 and the exhaust valve 5. The function of the exhaust valve 5 is to prevent water from entering the pressure cylinder 4. If water enters the pressure cylinder 4, it may cause ice to form inside the pressure cylinder 4, ultimately preventing the pressure cylinder 4 from injecting air normally. Therefore, the exhaust valve 5 increases the operational stability of the equipment.
