AI Technical Summary
In rural water supply projects in cold regions, existing antifreeze measures are ineffective, easily leading to frozen water pipes and damaged valves, affecting normal water use and wasting water resources.
The device system, which uses a combination of solenoid valves, controls the water flow through a rotary electric switch to prevent the water pipes from freezing by allowing residual water to flow back. It includes normally closed and normally open solenoid valves connected by a three-way valve and linked with the solenoid switch to control the flow of water and ensure that the water pipes do not freeze.
It effectively prevents water pipes from freezing, ensures normal water use, reduces water waste, improves the reliability and simplicity of the device, and is suitable for large-scale promotion.

Abstract
Description
[0001] The invention relates to a component system in the field of mechanical engineering, in particular to a household antifreeze faucet device in rural areas of cold regions. Background Art
[0002] Rural water supply projects in my country's extremely cold Northeast and North China regions, as well as high-altitude areas such as the Qinghai-Tibet Plateau, are prone to frost damage. The freezing period in Northeast and North China is as long as 3 to 6 months. In recent years, with the increase and intensification of extreme weather due to global climate change, the sudden drop in winter temperature has also had a great impact on the winter rural water supply in many non-traditional cold regions in my country, and farmers cannot use tap water stably and normally. In order to ensure that the water pipes are not frozen, farmers now use cotton wool wrapping for insulation, heating tape, and long-term water flow at night or during low temperature periods. However, there are still poor antifreeze effects and waste of water resources. In particular, once there is a slight negligence, the pipe valves are easily damaged by freezing, which affects farmers' water use. The invention of a simple, reliable, and large-scale antifreeze faucet device has important convenience and benefit significance for the people, and its products have broad market prospects. Summary of the invention
[0003] The purpose of the present invention is to overcome the above shortcomings and provide a device system with electromagnetic valve combination connection and electromagnetic switch linkage control, so as to realize normal water use for the masses in extremely cold weather and effectively solve the problem of freezing of farmers' outdoor water pipes. The present invention adopts a normally closed electromagnetic valve and a normally open electromagnetic valve through a three-way combination, and controls the on-off through a rotary electric switch (simulated faucet) to realize water supply and stop. After the water is stopped, the remaining water in the water pipe above the ground frozen soil layer flows back and seeps to keep the water outlet pipe hollow, thereby achieving the purpose of antifreeze. BRIEF DESCRIPTION OF THE DRAWINGS See the schematic diagram of the device for details. Figure 1 It is a schematic diagram of power supply and water supply; Figure 2 This is a schematic diagram of water leakage when power is off; when power is on, the normally closed valve is energized to open, the normally open valve is energized to close, and the water pipe supplies water normally; when power is off, the normally closed valve loses power and closes to stop water flow, the normally open valve loses power and opens, and the remaining water in the water pipe is discharged into the ground.
Claims
1. A household antifreeze faucet device for rural households in cold areas, comprising a solenoid valve assembly, a power adapter, a rotary electric switch, wiring, etc. Its characteristics are: Two solenoid valves are connected into a combination through a tee, and installed on the household water supply pipe below the frozen soil layer near the bottom of the water outlet to achieve an effective anti-freeze effect; a power adapter is configured to provide a 12V to 36V safe voltage for the solenoid valve; a rotary electric switch is configured to control the opening and closing of the solenoid valve.
