Description

Technical Field

[0001] This invention relates to the field of air purification technology, specifically to a forest fresh air compression and release device. Background Technology

[0002] With accelerating urbanization and increasingly severe environmental pollution, people's demand for a healthy living environment is constantly rising. Forest fresh air, rich in negative oxygen ions and low in pollutant concentrations, is widely recognized for its benefits in improving indoor air quality, alleviating respiratory illnesses, and enhancing mental health. Therefore, developing efficient and reliable forest fresh air compression and release devices has become an important research direction in the field of air purification technology.

[0003] For example, Chinese Patent (Publication No.: CN205351636U) discloses "an indoor fresh air storage and release device, comprising an air compressor, a compressed air storage system, an air supply pipeline, an air release system, and a branch pipeline, wherein the compressed gas output port of the air compressor is connected to the air inlet of the compressed air storage system, the exhaust port of the compressed air storage system is connected to one end of the air supply pipeline, the air supply pipeline is connected to the air release system through the branch pipeline, and the air release system is installed indoors."

[0004] However, existing technologies have some technical shortcomings in practical applications, as follows: First, in existing air compression and release devices, the temperature of fresh forest air increases significantly after compression (e.g., due to adiabatic compression). This leads to large pressure fluctuations in the compressed air within the storage tank, making stable storage difficult. For example, when hot air enters the storage tank, thermal expansion and contraction can cause sudden pressure changes, affecting the uniformity and safety of the release. More seriously, unstable pressure shortens the lifespan of the storage tank and increases the risk of leakage. Users often need additional pressure stabilization equipment, which not only increases costs but also reduces the system's portability and reliability. Secondly, forest air is typically humid, and water vapor easily condenses into liquid water during compression. Existing devices are not efficient enough in their cooling process, resulting in insufficient removal of water vapor. This condensate accumulates in the storage tank or pipes, causing excessive humidity and creating a breeding ground for bacteria and mold. Prolonged use may release polluted air, harming user health. Simultaneously, the moisture accelerates the corrosion of metal components (such as the inner wall of the storage tank), shortening the equipment's lifespan. Summary of the Invention

[0017] 2. During the cooling process, the water vapor in the high-humidity air condenses into liquid water inside the cylinder and is discharged through the drainage device; at the same time, the baffle plate extends the air path, improves the condensation efficiency, prevents water vapor from entering the air storage tank, eliminates the risk of bacterial growth and metal corrosion, and ensures air quality and equipment life.

[0018] 3. The water supply mechanism uses a negative pressure component to drive a motor, which in turn drives a piston to intermittently deliver cooling water. The return pipe and drain pipe recycle the water back to the water tank. Only a single motor is needed to drive the entire system. The cooling water is recycled, reducing energy and water consumption and greatly lowering operating costs. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] This application discloses a forest fresh air compression and release device. Please refer to [link / reference]. Figure 1 and Figure 2A forest fresh air compression and release device includes a base 1, a gas storage tank 2 fixedly connected to the top of the base 1, an outlet pipe 21 fixedly connected to one end of the gas storage tank 2, and a first control valve 22 fixedly connected to the outlet pipe 21; a mounting frame 3 fixedly connected to the top of the gas storage tank 2, a compressor body 5 fixedly mounted to one end of the top of the mounting frame 3, a motor 4 fixedly mounted to the other end of the top of the mounting frame 3, a transmission pulley 7 fixedly connected to the output shaft of the motor 4, an inner fan impeller 6 fixedly connected to the rotating screw of the compressor body 5, the inner fan impeller 6 and the transmission pulley 7 being connected by belt drive, an inlet pipe 51 fixedly connected to the air inlet of the compressor body 5, a filter 52 fixedly connected to the inlet end of the air inlet pipe 51, a cooling mechanism 8 connected to the air outlet of the compressor body 5, the air outlet of the cooling mechanism 8 communicating with the inside of the gas storage tank 2, and a water supply mechanism 9 provided on the base 1 to introduce cooling water into the cooling mechanism 8 in conjunction with the start of the motor 4.

[0024] By starting the motor 4, the transmission pulley 7 is driven to rotate, which in turn causes the inner fan impeller 6 to drive the rotating screw of the compressor body 5 to rotate. This allows the intake pipe 51 to introduce fresh forest air into the compressor body 5 for compression. At the same time, the filter 52 filters out large impurities and insects in the air, thus maintaining the cleanliness of the air introduced into the compressor body 5. After being compressed by the compressor body 5, the fresh forest air is introduced into the cooling mechanism 8 to cool and reduce the air pressure, and then introduced into the air storage tank 2 for storage. This keeps the air pressure inside the air storage tank 2 stable. By opening the first control valve 22, the fresh air inside the air storage tank 2 can be discharged into the surrounding environment. This allows fresh forest air to be collected and released into a specific environment to improve local air quality, simulate a forest environment, and provide health benefits to people.

[0025] Please see Figures 1-3 The cooling mechanism 8 includes a cylindrical body 81 fixedly connected to the base 1. Two baffles 82 are fixedly connected to both ends of the inner side of the cylindrical body 81. A plurality of evenly distributed heat exchange tubes 83 are fixedly connected between the two baffles 82. A water inlet pipe 84 is fixedly connected to one end of the cylindrical body 81, with its inlet end connected to the outlet end of the water supply mechanism 9. The water inlet pipe 84 is also connected to the inlet ends of the plurality of heat exchange tubes 83. A return water pipe 85 is fixedly connected to the other end of the cylindrical body 81, and the return water pipe 85 is connected to the plurality of heat exchange tubes... The outlet end of 83 is connected, and a first air guide pipe 86 is fixedly connected to one end of the top of the cylinder 81. The inlet end of the first air guide pipe 86 is connected to the air outlet of the compressor body 5. A second air guide pipe 87 is fixedly connected to the other end of the top of the cylinder 81. The outlet end of the second air guide pipe 87 is connected to the inside of the air storage tank 2. An inlet one-way valve 861 is fixedly connected to the first air guide pipe 86, and an outlet one-way valve 871 is fixedly connected to the second air guide pipe 87. A drain piece 89 is provided at the bottom of the cylinder 81.

[0026] By starting the motor 4, the transmission pulley 7 is driven to rotate, which in turn causes the inner fan impeller 6 to drive the rotating screw of the compressor body 5 to rotate. This causes the intake pipe 51 to introduce fresh forest air into the compressor body 5 for compression. After being compressed by the compressor body 5, the fresh forest air is introduced into the first air guide pipe 86. Then, through the first air guide pipe 86, the compressed air is introduced into the cylinder 81 to contact the heat exchange pipe 83. At the same time, the water supply mechanism 9 introduces cooling water into the water inlet pipe 84, which then continues to flow into the heat exchange pipe 83 to exchange heat with the air, thereby cooling the compressed air. This not only reduces the temperature of the compressed air and decreases the air pressure inside the air storage tank 2 to maintain stable air pressure, but also condenses the water vapor in the compressed air into water droplets that accumulate inside the cylinder 81. This avoids the problem of excessive humidity inside the air storage tank 2, which can lead to bacterial growth and corrosion of the tank.

[0027] Among them, a number of parallel baffles 88 are arranged between the two baffles 82. The baffles 88 are fixedly connected to the inner side of the cylinder 81. The baffles 88 are staggered up and down along the axis of the cylinder 81 and form an S-shaped channel.

[0028] The S-shaped channel formed by the baffle 88 can greatly extend the flow path of compressed air inside the cylinder 81, which can also extend the contact time between the compressed air and the heat exchange tube 83. This allows the compressed air and cooling water to exchange heat fully, greatly improving the cooling effect of the compressed air.

[0029] Please see Figure 1 and 4 The water supply mechanism 9 includes a water tank 91 fixedly connected to the top of the base 1. A water guide pipe 92 is fixedly connected to the outlet end of the water tank 91. A negative pressure component 93 is provided at the outlet end of the water guide pipe 92, which, in conjunction with the start of the motor 4, intermittently introduces the cooling water in the water tank 91 into the water inlet pipe 84. The outlet end of the return water pipe 85 is connected to the water tank 91.

[0030] After the motor 4 starts, the negative pressure component 93 intermittently introduces the cooling water in the water tank 91 into the water inlet pipe 84, thus realizing the intermittent flow of water inside the heat exchange tube 83. This not only allows the cooling water to quickly remove the heat of the compressed air, but also effectively reduces the consumption of cooling water and further improves the cooling effect of the compressed air. At the same time, the return water pipe 85 introduces the cooling water back into the water tank 91 for recycling, saving water resources and effectively reducing the operating cost of the device.

[0031] Please see Figure 1 and 5The drainage component 89 includes several drainage pipes 891 that are equidistantly distributed along the axis of the cylinder 81. The top ends of the drainage pipes 891 are connected to the inside of the cylinder 81, and the bottom of the drainage pipes 891 are fixedly connected to a confluence pipe 892. The outlet end of the confluence pipe 892 is connected to the water tank 91, and a second control valve 893 is fixedly connected to each of the drainage pipes 891.

[0032] By opening the second control valve 893, the condensate inside the cylinder 81 can be discharged, then flow into the confluence pipe 892, and then be centrally introduced into the water tank 91 for reuse, further saving water resources.

[0033] Please see Figure 1 and 7 The negative pressure component 93 includes a transition cylinder 931 fixedly connected to the outside of the gas storage tank 2. A push-pull rod 932 that penetrates the top wall of the transition cylinder 931 is slidably connected to the top of the transition cylinder 931. A piston 933 is fixedly connected to the bottom of the push-pull rod 932. The piston 933 is slidably connected to the inner wall of the transition cylinder 931. A linkage 934 is provided at the top of the push-pull rod 932 to drive the push-pull rod 932 to slide up and down repeatedly by cooperating with the start of the motor 4. A water inlet check valve 935 is fixedly connected to the inlet end of the transition cylinder 931. The inlet end of the water inlet check valve 935 is connected to the water guide pipe 92. A water outlet check valve 936 is fixedly connected to the outlet end of the transition cylinder 931. The outlet end of the water outlet check valve 936 is connected to the water inlet pipe 84. The linkage 934 includes a connecting seat 9341 fixedly connected to the top of the push-pull rod 932. The top of the connecting seat 9341 is hinged to the connecting rod 9342. A cam 9343 is rotatably connected to one side of the mounting bracket 3. The outer edge of the cam 9343 is rotatably connected to one end of the connecting rod 9342. A first gear 9344 is coaxially fixedly connected to the cam 9343. A second gear 9345 is also fixedly connected to the output shaft of the motor 4. The second gear 9345 meshes with the first gear 9344.

[0034] Working principle: First, the motor 4 is started to drive the transmission pulley 7 to rotate, which causes the inner fan impeller 6 to drive the rotating screw of the compressor body 5 to rotate, so that the air intake pipe 51 introduces fresh forest air into the compressor body 5 for compression. After being compressed by the compressor body 5, the fresh forest air is introduced into the first air guide pipe 86, and then the compressed air is introduced into the cylinder 81 through the first air guide pipe 86 to contact the heat exchange tube 83. After motor 4 starts, the second gear 9345 rotates synchronously, causing the first gear 9344 to drive the cam 9343 to rotate. This causes the connecting rod 9342 to move the connecting seat 9341 and the push-pull rod 932 up and down, causing the piston 933 to slide back and forth inside the transition cylinder 931. This causes the pressure inside the transition cylinder 931 to periodically decrease and increase. When the pressure inside the transition cylinder 931 decreases, the water guide pipe 92 introduces cooling water from the water tank 91 into the transition cylinder 931; when the pressure inside the transition cylinder 931 increases, the water inlet pipe 84 introduces cooling water from the transition cylinder 931 into the heat exchange tube 83. This cycle continues, with the water inlet pipe 84 periodically introducing cooling water into the heat exchange tube. Cooling water is introduced into the heat exchange tube 83, and the cooling water flowing into the heat exchange tube 83 exchanges heat with the air, thereby cooling the compressed air. Since the water inside the heat exchange tube 83 flows intermittently, it can not only quickly remove the heat of the compressed air through the flow of cooling water, but also effectively reduce the consumption of cooling water, further improve the cooling effect of the compressed air, and make the temperature of the compressed air drop rapidly, thereby reducing the air pressure inside the air storage tank 2 to maintain stable air pressure. It can also condense the water vapor in the compressed air into water droplets and collect them inside the cylinder 81, thereby avoiding the problem of water vapor entering the air storage tank 2 and causing excessive humidity inside the air storage tank 2, which can breed bacteria and corrode the tank. By opening the second control valve 893, the condensate inside the cylinder 81 can be discharged, then flow into the confluence pipe 892, and then be centrally introduced into the water tank 91 for reuse, further saving water resources.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
