Description

Technical Field

[0001] The invention relates to an energy-free automatic gas storage type antifreeze faucet, belonging to the technical field of faucet antifreeze. Background Art

[0002] Water is an essential resource for human survival, and it's indispensable in every aspect of life and production. However, its use can be a source of considerable trouble, especially for those living in the Northern Hemisphere. Outdoor faucets often present a challenge every winter, as low temperatures can cause ice to form inside, pipes to rupture, or outlets to become clogged. A wide variety of antifreeze measures have emerged for faucets, including draining, aerating, heating, and insulation systems.

[0003] The principle of an emptying faucet is that after closing the valve, the internal structure empties the residual water to avoid freezing, such as the antifreeze device for a faucet disclosed in CN201720109916.X.

[0004] The principle of an inflatable faucet is to use an air nozzle to inflate the inside of the faucet to prevent freezing after closing the valve, such as the antifreeze device of the faucet disclosed in CN201310453884.1.

[0005] The principle of a heated faucet is to have a built-in electric heating element or heating tape to prevent freezing by heating, such as the faucet antifreeze device disclosed in CN201620443739.4.

[0006] The principle of an insulated faucet is to wrap the outer layer with insulation material to reduce heat loss, such as the antifreeze faucet disclosed in CN202322943269.0.

[0007] The technical solutions disclosed in the above patent documents are found to still have the following technical problems in practice: For emptying and aerating faucets, draining or aerating them must be done after the faucet is turned off. This is cumbersome and relies on manual intervention, which can be easily forgotten or neglected. If forgotten (especially in emergency shutdowns or rush situations), the remaining water can directly lead to the risk of pipes freezing and cracking. This also creates the problem of repetitive labor, with frequent opening and closing of the faucet requiring repeated operation. Long-term use can be inconvenient for users, especially in frequently used public places. Furthermore, emptying requires opening a specific valve and maintaining a draining posture, while aerating requires connecting an air pump and controlling the air pressure, making it unsuitable for the elderly, children, or those with limited mobility.

[0008] While heated and insulated frost-resistant faucets can prevent pipes from freezing through active heating or passive insulation, they have the following drawbacks: Heated frost-resistant faucets rely on electricity and become ineffective during power outages. During extreme weather conditions, the heating function ceases completely, potentially causing pipes to freeze rapidly. Furthermore, they suffer from high energy consumption and operating costs. The electric heating cables or built-in heating elements require prolonged operation (especially in extremely low temperatures), significantly increasing electricity bills. Insulated frost-resistant faucets are only suitable for mildly cold environments. The insulation layer only slows heat loss and does not actively increase temperature, so freezing is still a concern during sustained low temperatures or extreme cold snaps.

[0009] In summary, the existing technologies are obviously inconvenient and defective in actual use, and none of them fundamentally solves the antifreeze problem. Summary of the Invention

[0010] The present invention addresses the shortcomings of the prior art and provides an energy-free, automatic, gas-storage, antifreeze faucet. This faucet, which requires no external energy or manual intervention, utilizes the flow of tap water to automatically store gas. The gas storage structure is rationally integrated with the faucet's internal structure to automatically complete the gas storage, exhaust, and drainage processes, effectively preventing the faucet and pipes from freezing. This fundamentally solves the problem of energy waste and allows users to turn the faucet off and on, even in winter, eliminating the need for complex antifreeze measures and eliminating the need to worry about the faucet freezing due to forgotten antifreeze measures.

[0011] In order to solve the above technical problems, the present invention adopts the following technical solutions: The energy-free automatic gas storage antifreeze faucet comprises a faucet body, which is installed at the end of the water inlet pipe. A rotatable cylinder is installed in the faucet body, a fan blade is installed inside the cylinder, and a bevel gear is fixedly installed on the cylinder. An air compressor housing is installed at the bottom of the faucet body. A horizontally arranged movable shaft is installed inside the air compressor housing. A separation gear is installed on the movable shaft and meshes with the helical gear. The separation gear is positioned on both sides by C-shaped retaining springs. A vertically arranged crankshaft is installed inside the air compressor housing. A bevel gear is installed on the top of the crankshaft and meshes with the separation gear. The crankshaft is connected to the piston through a horizontally arranged connecting rod. The crankshaft drives the piston to reciprocate to generate air pressure, which is stored in the air tank. A double-ball valve core is also installed inside the faucet body. A water flow channel is provided in the upper ball structure of the valve core, and a gas flow channel is provided in the lower ball structure of the valve core. The water flow channel and the gas flow channel are opened alternately.

[0012] Furthermore, the outer wall of the cylinder is connected to the inner wall of the faucet body through two bearings arranged side by side. The fan blades drive the cylinder to rotate along the bearings under the impact of the water flow; water seals are installed on the outer sides of both ends of the cylinder.

[0013] Furthermore, the separation gear is composed of two parts, one part is a helical gear structure that can mesh with the helical gear for transmission, and the other part is a bevel gear structure that can mesh with the bevel gear for transmission.

[0014] Furthermore, the bottom of the crankshaft is rotatably mounted on the bottom of the inner cavity of the air compressor housing, and the top of the crankshaft is connected to the bracket through a shoe seat.

[0015] Furthermore, the piston is slidably arranged in the cylinder a, and the cylinder a is fixed on the side wall of the air compressor housing. A closed cavity is formed between the piston and the cylinder a, and the side air intake one-way valve of the closed cavity is connected to the air storage tank through a pipeline.

[0016] Furthermore, one end of the movable shaft is slidably arranged in the cylinder b, and the cylinder b is fixed on the side wall of the air compressor housing. A closed cavity is formed between the end of the movable shaft and the cylinder b, and the side of the closed cavity is connected to the air storage tank through a pipeline.

[0017] Furthermore, the other end of the movable shaft is mounted on the other side wall of the air compressor housing. The end of the movable shaft is sequentially provided with a spring and an air pressure regulating knob, and the air pressure regulating knob is threadedly connected to the side wall of the air compressor housing.

[0018] Furthermore, a valve seat is installed inside the faucet body, and a valve core is installed inside the valve seat; a water outlet hole is provided through the valve seat, and the water outlet hole is adapted to the position of the water flow channel.

[0019] Furthermore, a gas injection hole is provided on one side of the valve seat close to the cylinder, and the gas injection hole can be connected to the top of the gas flow channel, and the bottom of the gas flow channel is connected to the gas storage tank through a pipeline.

[0020] Furthermore, a pressure gauge is installed on the gas storage tank.

[0021] After adopting the above technical solution, the present invention has the following advantages compared with the prior art: The present invention does not need to rely on external energy or human intervention. It uses the flow of tap water itself to automatically store gas and reasonably combines the gas storage structure with the internal structure of the faucet. The faucet can be opened and closed at any time. When the faucet is closed, a cavity is formed in the pipe to achieve anti-freeze. No secondary operation is required, which can fundamentally solve the problem of energy waste. Even in winter, it can be turned off and left at any time, eliminating the implementation of many complicated anti-freeze measures and there is no need to worry about the faucet being damaged by freezing due to forgetting to do anti-freeze.

DETAILED DESCRIPTION

[0025] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0026] like Figure 1-Figure 3 As shown together, the present invention provides an energy-free automatic air storage antifreeze faucet, comprising a faucet body 2 , which is installed at the end of a water inlet pipe 1 .

[0027] A rotatable cylinder 3 is installed in the faucet body 2. The outer wall of the cylinder 3 is connected to the inner wall of the faucet body 2 through two bearings 5 arranged side by side. A fan blade 4 is installed inside the cylinder 3. The fan blade 4 drives the cylinder 3 to rotate along the bearing 5 under the impact of the water flow.

[0028] Water seals 6 are installed on the outer sides of both ends of the cylinder 3 to prevent water flow from entering the annular cavity between the cylinder 3 and the faucet main body 2. A bevel gear 7 is fixedly installed on the cylinder 3.

[0029] A compressed air housing 10 is mounted at the bottom of the faucet body 2. A horizontally arranged movable shaft 9 is mounted within the housing. Mounted on the movable shaft 9 is a release gear 8 that meshes with the helical gear 7. C-shaped retaining springs 19 secure the release gear 8 on either side. The release gear 8 and the movable shaft 9 can move laterally together but not rotate together. The movable shaft 9 can reciprocate laterally but cannot rotate, meaning that the release gear 8 does not transmit torque to the movable shaft 9. An opening is provided at the connection between the faucet body 2 and the compressed air housing 10 to prevent movement of the release gear 8.

[0030] A vertically mounted crankshaft 12 is mounted on top of the air compressor housing 10. A bevel gear 11 is mounted on top of the crankshaft 12 and engages with the separation gear 8. The separation gear 8 consists of two parts: one part is a helical gear structure that engages with the helical gear 7, and the other part is a bevel gear structure that engages with the bevel gear 11.

[0031] The bottom of the crankshaft 12 is rotatably mounted on the bottom of the inner cavity of the air compressor housing 10, and the top of the crankshaft 12 is connected to the bracket 23 through the shoe seat 22. The bracket 23 is fixed to the inner wall of the air compressor housing 10 to provide rotational support for the top of the crankshaft 12 to ensure the stability of the crankshaft 12 during rotation.

[0032] Crankshaft 12 is connected to piston 13 via a horizontal connecting rod. Piston 13 slides within cylinder a14, which is fixed to the sidewall of the air compressor housing 10. A sealed chamber is formed between piston 13 and cylinder a14. An inlet check valve 15 and an outlet check valve 16 are mounted on the sides of the sealed chamber. Outlet check valve 16 is connected to an air storage tank 17 via a pipeline. Crankshaft 12 drives piston 13 on the connecting rod to reciprocate within cylinder a14, generating air pressure that is stored in air storage tank 17.

[0033] One end of the movable shaft 9 slides within a cylinder b18, which is fixed to the sidewall of the air compressor housing 10. A sealed chamber is formed between the end of the movable shaft 9 and the cylinder b18. The side of the sealed chamber is connected to the air tank 17 via a pipeline. When the air pressure in the air tank 17 reaches the set pressure, high-pressure gas can enter the sealed chamber through the pipeline and be directed to the end of the movable shaft 9. The movable shaft 9 drives the separation gear 8 to move left, thereby disconnecting the power transmission between the helical gear 7 and the bevel gear 11. At this time, the helical gear 7 is in an idling state.

[0034] The other end of the movable shaft 9 is mounted on the other side wall of the air compressor housing 10 . A spring 20 and an air pressure regulating knob 21 are sequentially provided on the end of the movable shaft 9 . The air pressure regulating knob 21 is threadedly connected to the side wall of the air compressor housing 10 .

[0035] A water outlet 32 is provided on a side of the faucet body 2 away from the water inlet pipe 1 .

[0036] A valve seat 25 is further installed inside the faucet body 2 , and a valve core 24 is installed inside the valve seat 25 . The top of the valve core 24 is connected to a handle 31 , and the handle 31 drives the valve core 24 to rotate inside the valve seat 25 .

[0037] The valve core 24 is a double-ball structure. A water flow channel 27 is provided in the upper ball structure of the valve core 24, and a gas flow channel 29 is provided in the lower ball structure of the valve core 24. The water flow channel 27 and the gas flow channel 29 are opened alternately. When the water flow channel 27 is in the open state, the gas flow channel 29 is in the blocked state. When the water flow channel 27 is in the blocked state, the gas flow channel 29 is in the open state.

[0038] The valve seat 25 has a water outlet hole 26 extending therethrough. The water outlet hole 26 is aligned with the water flow channel 27 . After the water outlet hole 26 is connected to the water flow channel 27 , water in the water inlet pipe 1 can flow to the water outlet 32 .

[0039] The valve seat 25 is provided with a gas injection hole 28 on one side close to the cylinder 3 . The gas injection hole 28 can be connected to the top of the gas flow channel 29 . The bottom of the gas flow channel 29 is connected to the gas storage tank 17 through a pipeline.

[0040] A pressure gauge 30 is installed on the gas storage tank 17 .

[0041] The specific working principle of the present invention is: The present invention utilizes water flow as a power source. Tap water flows in through the cylinder 3, impacting the fan blades 4 and causing them to rotate. The fan blades 4 transmit force to the separation gear 8 and the bevel gear 11 in sequence through the external helical gear 7, causing the crankshaft 12 to drive the piston 13 on the connecting rod to reciprocate within the cylinder a14, generating air pressure that is stored in the air tank 17. When the air pressure in the air tank 17 reaches the set requirement, the high-pressure gas can enter the closed chamber along the upper pipeline and be directed to the end of the movable shaft 9, causing the spring 20 to be compressed, causing the movable shaft 9 to drive the separation gear 8 to move left, thereby disconnecting the power transmission between the helical gear 7 and the bevel gear 11. At this time, the helical gear 7 is in an idling state.

[0042] When the faucet is closed, that is, the water flow channel 27 in the valve core 24 is blocked and the gas flow channel 29 is open, the water flow stops, the fan blades 4 stop rotating, and the high-pressure gas in the gas tank 17 enters the water inlet pipe 1 through the gas flow channel 29 and the gas injection hole 28, causing the tap water in the water inlet pipe 1 to be pushed back and form a cavity. The gas will use this to press the tap water level below the ground or press the tap water into the room, thereby achieving an anti-freeze effect. When the gas pressure in the gas tank 17 decreases, the movable shaft 9 and the separation gear 8 return to their original position under the elastic force of the spring 20, and the separation gear 8 once again meshes with the helical gear 7 and the bevel gear 11.

[0043] When the faucet is turned on again, the water flow channel 27 in the valve core 24 is in the open state, the gas flow channel 29 is in the blocked state, the high-pressure gas in the water inlet pipe 1 is discharged, the water flow is formed, and the fan blades 4 start to drive the crankshaft 12 to work again to store gas in the gas tank 17, preparing for the next time the faucet is closed.

[0044] The present invention makes good use of the flow of tap water itself as the power of the device, without relying on external energy or human intervention, and reasonably combines the gas storage structure with the internal structure of the faucet, which can fundamentally solve the problem of energy waste. Even in winter, it can be turned off and left at will, eliminating the implementation of many complicated anti-freeze measures, and there is no need to worry about the faucet being damaged by freezing due to forgetting to do anti-freeze.

[0045] The foregoing is an example of the best mode of carrying out the present invention. Any portion not described in detail herein is common knowledge within the skill of one of ordinary skill in the art. The scope of protection of the present invention is determined by the claims. Any equivalent transformation based on the technical teachings of the present invention is also within the scope of protection of the present invention.
