Description

Technical Field

[0001] This application relates to the field of air purification equipment technology, specifically to an ecological negative oxygen ion high-efficiency generator. Background Technology

[0002] Ecological negative oxygen ions refer to negative oxygen ions generated in nature or produced by imitating natural principles, which are equivalent to those in nature and have good therapeutic effects on the human body. Negative oxygen ions can promote the synthesis and storage of vitamins in the human body, strengthen and activate the body's physiological activities, so they are also known as "air vitamins". Furthermore, negative oxygen ions can absorb dust particles in the air and have the effect of purifying the air. Therefore, the production of negative oxygen ions is particularly important.

[0003] Most negative ion generators on the market currently use "ionization" technology, which generates negative ions by electrocuting the air with high voltage. While this technology is effective in generating negative ions, some oxygen molecules may become ozone molecules during the process. This is because oxygen molecules may absorb enough energy during ionization to break into two separate oxygen atoms. These two oxygen atoms then combine with unionized oxygen molecules to form ozone molecules. Although ozone can block ultraviolet rays in the upper atmosphere, if its concentration exceeds safe levels indoors, it can become a "hidden killer" of health. Furthermore, negative ions tend to accumulate near the electrodes, blocking the generation of other negative ions and affecting the generation efficiency. Additionally, the electrodes are prone to static electricity, attracting surrounding dust particles to their surface, reducing surface activity and further impacting negative ion generation efficiency. Summary of the Invention

[0004] To address the technical problem of low negative ion generation efficiency in existing ionization-type negative ion generators and improve negative ion generation efficiency, an eco-friendly high-efficiency negative ion generator is provided. The device includes a housing, inside which is an ultrasonic transducer connected to multiple discharge terminals. The ultrasonic transducer is connected to an ultrasonic generating structure for driving its vibration. The discharge terminals are connected to a negative ion controller for controlling the discharge from the discharge terminals.

[0005] Through the above technical solution, an ultrasonic transducer is set up to generate ultrasonic waves. When the ultrasonic waves propagate in the air, they produce a weak "cavitation effect," that is, the formation of tiny low-pressure bubbles in localized areas that burst rapidly. This instantaneous pressure change can lower the air breakdown threshold, making corona discharge easier to occur, thereby generating more negative ions under the same voltage and improving the generation efficiency of negative ions. At the same time, the negative ions generated by corona discharge tend to accumulate near the electrodes, forming "ion clouds" and reducing the effective concentration. However, the high-frequency vibration of the ultrasonic waves can generate strong micro-convection in the air, effectively dispersing these accumulated ions and making their diffusion more uniform. This increases the contact area between negative ions and air, increasing the binding efficiency of negative ions and oxygen ions, thereby improving the generation efficiency of negative oxygen ions. In addition, the ultrasonic vibration can shake off dust, oil, or oxides adhering to the surface of the corona discharge terminal, maintaining the activity of the electrode surface and avoiding discharge instability or efficiency reduction caused by contamination, thus ensuring the long-term stability of negative oxygen ion generation.

[0006] Optionally, multiple ultrasonic transducers are provided, each ultrasonic transducer is circular, and the diameter of each ultrasonic transducer is 5-8 mm.

[0007] If the ultrasonic transducer is too large, it will not only make ultrasonic oscillation more difficult, but also cause excessive deviation in the vibration amplitude of the discharge terminals located at different positions of the ultrasonic transducer. With the above technical solution, multiple circular ultrasonic transducers can be evenly distributed in the housing, expanding the vibration coverage range and ensuring that the vibration amplitude of each discharge terminal is basically the same. The 5-8mm diameter design balances vibration strength and installation space, generating sufficient vibration force without occupying too much internal space of the housing, and adapting to the overall structural layout of the device.

[0008] Optionally, a base plate is provided inside the housing, and multiple holes are formed on the surface of the base plate.

[0009] Dust shaken off from the ultrasonic transducers falls onto the base plate. However, there are many gaps between the multiple ultrasonic transducers, making it difficult to clean the dust that falls into them. In addition, the ultrasonic transducers may be damaged during the cleaning process. The above technical solution involves opening multiple holes in the base plate, allowing the dust shaken off from the ultrasonic transducers to fall through the holes to the bottom of the housing, which facilitates the cleaning of the base plate.

[0010] Optionally, the housing is connected to a heating structure located above the ultrasonic transducer. The heating structure includes a heating shell with a heating tube spirally wound around its outer side.

[0011] During the process of generating negative ions through discharge, some ozone is produced. Although ozone can be reduced to oxygen, the reduction efficiency is too slow at room temperature. Through the above technical solution, the ionized air is introduced into the heating structure for heating, thereby improving the efficiency of ozone reduction to oxygen and inhibiting ozone emission. At the same time, heating can also break up the negative oxygen ions that have gathered together due to static electricity into small-particle, highly active, high-purity, ozone-free, and long-distance ecological-grade negative oxygen ions.

[0012] Optionally, a cooling channel is connected above the housing, the cooling channel comprising a spirally rising pipe.

[0013] If heated air is directly discharged from the generator, it may cause the ambient temperature to rise. The above technical solution sets up a cooling channel to cool the heated air. The spiral cooling channel extends the flow path of the hot air, allowing the heated air to be fully cooled in the channel. At the same time, the spiral structure increases the heat exchange area with the outside, improves the cooling efficiency, ensures that the discharged negative oxygen ion air is at a suitable temperature, and can be further mixed evenly during the flow process, thus improving the diffusion effect.

[0014] Optionally, a water storage tank is provided above the housing, and a cooling channel is provided inside the water storage tank. Multiple evaporation ports are provided on the upper surface of the water storage tank. The evaporation ports include multiple through holes distributed in a fan shape, and the multiple evaporation ports are arranged in a circumferential array above the water storage tank. A rotating door is rotatably connected above the water storage tank. The rotating door includes a fan-shaped plate with the same shape and number as the evaporation ports. The rotating door is used to block or open the evaporation ports.

[0015] Through the above technical solution, the liquid in the water tank can exchange heat with the hot air in the cooling channel, further increasing the cooling effect of the hot air. In addition, the water in the water tank absorbs heat energy and its temperature rises. When the environment is too dry, the operator can open the rotating door to allow the water in the water tank to evaporate and be discharged from the evaporation port, thereby increasing the humidity of the air in the environment. When there is no need to increase the humidity of the environment, the rotating door can simply be closed.

[0016] Optionally, a drip cap is provided above the cooling channel. The drip cap is conical. A water guide pipe is connected above the water storage tank. The water guide pipe is sleeved on the outer side of the cooling channel located above the water storage tank. A baffle is provided at the lower end of the water guide pipe. The baffle has a through hole and a sponge plug is provided in the through hole. When water vapor condenses on the drip cap, water droplets enter the water guide pipe.

[0017] Through the above technical solution, the water vapor in the air discharged from the cooling channel is cooled and liquefied on the drip cap, and drips down into the water guide pipe along the drip cap, and enters the water storage tank through the sponge plug, thereby reducing the moisture content of the air discharged from the cooling channel and achieving the dehumidification effect. At the same time, when humidifying the air is needed, simply open the rotating door.

[0018] Optionally, the housing surface is provided with an air inlet for air to enter, and a filter screen is provided at the air inlet.

[0019] Through the above technical solution, the air inlet provides a sufficient air source for the inside of the casing, ensuring the supply of raw materials for the generation of negative oxygen ions; the filter can filter dust and particulate matter in the air, reduce the adsorption of dust on the discharge terminal and ultrasonic transducer surface, reduce the cleaning frequency, and at the same time avoid impurities affecting the purity of negative oxygen ion generation.

[0020] Optionally, the shell has a cleaning opening on its circumferential surface. The cleaning opening is semi-circular, and a cleaning door is provided at the cleaning opening. The cleaning door is semi-circular and is slidably connected to the shell. A cleaning box is provided at the bottom inside the shell. The cleaning box contains cleaning liquid to dissolve and absorb the fallen dust. The cleaning box is separate from the shell.

[0021] With the above technical solution, when it is necessary to clean the inside of the housing, simply slide the cleaning door to open it, making it easy for the operator to clean the inside of the housing. At the same time, a cleaning box is set at the bottom of the housing so that the dust shaken off by the ultrasonic transducer falls into the cleaning box. Then, the operator only needs to take out the cleaning box at the cleaning port and replace the cleaning fluid inside.

[0022] Optionally, a movable cleaning brush is provided on one side of the cleaning door. When the cleaning door slides, the movable cleaning brush cleans the inner surface of the housing. A fixed cleaning brush is provided on the inner side of the housing. When the cleaning door slides, the fixed cleaning brush cleans the inner surface of the cleaning door.

[0023] With the above technical solution, bidirectional cleaning can be achieved simultaneously when the cleaning door is slid open: when the operator opens the cleaning door, the cleaning door drives the moving cleaning brush to slide on the inner surface of the housing, so that the moving cleaning brush cleans the inner surface of the housing, while the fixed cleaning brush scrubs the surface of the cleaning door, cleaning the inner surface of the cleaning door at the same time, making the cleaning of the housing more convenient.

[0024] One or more technical solutions provided by this invention have at least the following technical effects or advantages:

[0025] 1. By combining an ultrasonic transducer with a discharge terminal, the generation efficiency of negative ions is improved. At the same time, the vibration shakes off the dust, oil, or oxides attached to the surface of the discharge terminal, ensuring the long-term stability of negative oxygen ion generation.

[0026] 2. By setting up a heating structure to heat the ionized air, the efficiency of ozone reduction to oxygen is accelerated, while negative oxygen ions are decomposed into smaller, more active ecological-grade negative oxygen ions.

[0027] 3. By setting up a water storage tank, the cooling speed of the air in the cooling channel can be accelerated. At the same time, the air humidity can be increased by opening the rotating door to allow the water in the water storage tank to evaporate. Attached Figure Description

[0036] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments of the present invention and the features thereof can be combined with each other.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0038] Reference Figure 1An ecological negative oxygen ion high-efficiency generator includes a housing 1, an ultrasonic transducer 2 is disposed inside the housing 1, the ultrasonic transducer 2 is connected to multiple discharge terminals 3, the ultrasonic transducer 2 is connected to an ultrasonic generating structure for driving the ultrasonic transducer 2 to vibrate, and the discharge terminals 3 are connected to a negative ion controller for controlling the discharge of the discharge terminals 3. The ultrasonic transducer 2 combines ultrasonic vibration with the generation of negative ions. When ultrasound propagates in the air, it produces a weak "cavitation effect," which involves the formation of tiny low-pressure bubbles that rapidly burst. This instantaneous pressure change lowers the air breakdown threshold, making corona discharge easier to occur. This results in the generation of more negative ions at the same voltage, improving the generation efficiency. Simultaneously, negative ions generated by corona discharge tend to accumulate near the electrodes, forming "ion clouds" and reducing the effective concentration. The high-frequency vibration of ultrasound generates strong micro-convection in the air, effectively dispersing these accumulated ions and making their diffusion more uniform, thereby improving the generation efficiency of negative oxygen ions. Furthermore, ultrasonic vibration can shake off dust, oil, or oxides adhering to the surface of the corona discharge terminal 3, maintaining the activity of the electrode surface and preventing discharge instability or efficiency reduction due to contamination, thus ensuring the long-term stability of negative oxygen ion generation.

[0039] Reference Figure 2 Multiple ultrasonic transducers 2 are provided, each being circular with a diameter of 5-8mm. A base plate 4 is located inside the housing 1, and the ultrasonic transducers 2 are mounted on the base plate 4, which is fixedly connected to the inside of the housing 1. The surface of the base plate 4 has multiple holes for air to pass through. The multiple circular ultrasonic transducers 2 can be evenly distributed within the housing 1, expanding the vibration coverage and ensuring that the vibration amplitude of each discharge terminal 3 is basically the same. The 5-8mm diameter design balances vibration strength and installation space, generating sufficient vibration force without occupying too much internal space in the housing 1, thus adapting to the overall structural layout of the device. The multiple holes on the base plate 4 allow dust shaken off by the ultrasonic transducers 2 to fall through the holes to the bottom of the housing, facilitating cleaning of the base plate 4.

[0040] Reference Figure 3 The housing 1 is connected to a heating structure 5, which is located above the ultrasonic transducer 2. The heating structure 5 includes a heating shell 51, with a heating tube 52 spirally wound around its outer side. Ozone may be generated during the discharge process of generating negative ions. Although ozone can be reduced to oxygen, the reduction efficiency is too slow at room temperature. Through the above technical solution, the ionized air is introduced into the heating structure 5 for heating. Preferably, the heating temperature is not less than 60°C. When the temperature is greater than 60°C, the efficiency of ozone reduction to oxygen is greatly improved, reducing ozone emissions. At the same time, heating can also disperse the negative oxygen ions that are statically aggregated into small-particle, highly active, high-purity, ozone-free, and long-distance ecological-grade negative oxygen ions.

[0041] Reference Figure 4 and Figure 5 A cooling channel 7 is connected to the top of the casing 1, and the cooling channel 7 includes a spirally rising pipe. A water storage tank 6 is installed above the casing 1, and the cooling channel 7 is located inside the water storage tank 6. The upper surface of the water storage tank 6 is provided with multiple evaporation ports 61, each including multiple through holes distributed in a fan shape, and the multiple evaporation ports 61 are arranged in a circumferential array above the water storage tank 6. A rotating door 62 is rotatably connected to the top of the water storage tank 6. The rotating door 62 includes fan-shaped plates with the same shape and number as the evaporation ports 61, and is used to block or open the evaporation ports 61. The cooling channel 7 is designed to cool the heated air. The spirally rising cooling channel 7 extends the flow path of the hot air, allowing the heated air to be fully cooled within the channel. At the same time, the spiral structure increases the heat exchange area with the outside environment, allowing the liquid in the water storage tank 6 to have sufficient heat exchange with the hot air in the cooling channel 7, further increasing the cooling effect of the hot air and ensuring that the temperature of the discharged negative oxygen ion air is suitable. In addition, the water in the water tank 6 absorbs heat and its temperature rises. When the environment is too dry, the operator can open the rotating door 62 to make the water in the water tank 6 evaporate and be discharged from the evaporation port 61, thereby increasing the humidity of the air in the environment. When there is no need to increase the humidity of the environment, simply close the rotating door 62.

[0042] A drip cap, conical in shape, is installed above the cooling channel 7. A water guide pipe 63 is connected above the water storage tank 6, fitting around the outer part of the cooling channel 7 above the water storage tank 6. A baffle 64 is installed at the lower end of the water guide pipe 63, with a through hole and a sponge plug 65 inside. When water vapor condenses on the drip cap, water droplets enter the water guide pipe 63. Water vapor in the air discharged from the cooling channel 7 cools and liquefies on the drip cap, dripping down the drip cap into the water guide pipe 63 and then through the sponge plug 65 into the water storage tank 6. This reduces the moisture content of the air discharged from the cooling channel 7, thus achieving dehumidification. To humidify the air, simply open the rotating door 62.

[0043] Reference Figure 6 The housing 1 has an air inlet 11 on its surface for air entry, and a filter screen is installed at the air inlet 11. The air inlet 11 provides a sufficient air source for the interior of the housing 1, ensuring the supply of raw materials for the generation of negative oxygen ions; the filter screen can filter dust, particulate matter and other impurities in the air, reduce the adsorption of dust on the surface of the discharge terminal 3 and the ultrasonic transducer 2, reduce the cleaning frequency, and at the same time prevent impurities from affecting the purity of negative oxygen ion generation.

[0044] The housing 1 has a cleaning opening on its circumferential surface, which is semi-circular. A cleaning door 12, also semi-circular, is located at the cleaning opening and is slidably connected to the housing. A cleaning box 13, containing cleaning fluid, is located at the lower interior of the housing 1. The cleaning box 13 is separate from the housing. A movable cleaning brush 14 is located on one side of the cleaning door 12. When the cleaning door 12 slides, the movable cleaning brush 14 cleans the inner surface of the housing 1. A fixed cleaning brush 15 is located inside the housing 1. When the cleaning door 12 slides, the fixed cleaning brush 15 cleans the inner surface of the cleaning door 12. When cleaning the inside of the housing 1 is required, simply slide the cleaning door 12 to open it. The cleaning door 12 will drive the movable cleaning brush to slide on the inner surface of the housing 1, so that the movable cleaning brush can clean the inner surface of the housing 1. At the same time, the fixed cleaning brush will scrub the surface of the cleaning door 12 and clean the inner surface of the cleaning door 12 simultaneously. The dust shaken off by the ultrasonic transducer 2 will fall into the cleaning box 13. Then, the operator only needs to take out the cleaning box 13 from the cleaning port and replace the cleaning solution inside.

[0045] The specific implementation of this embodiment is as follows: Air enters the interior of the housing 1 through the air inlet 11. The filter screen blocks some dust on the outside of the housing 1. The discharge terminal 3 discharges to ionize the air and form negative oxygen ions. At the same time, the ultrasonic transducer 2 vibrates to improve the efficiency of negative oxygen ion formation at the discharge terminal 3. The vibration of the ultrasonic transducer 2 causes dust and particles on the surface of the discharge terminal 3 to fall into the cleaning box 13 below. The ionized air enters the heating structure 5. The heating tube 52 heats the air, accelerating the decomposition of ozone in the air into oxygen. At the same time, it decomposes negative oxygen ions into smaller, more active ecological-grade negative oxygen ions. Subsequently, the air enters the cooling channel 7 for cooling. The water in the water tank 6 accelerates the cooling speed of the air. At the same time, the operator can open the rotating door 62 to allow the water in the water tank 6 to evaporate and be discharged through the evaporation port 61, increasing the humidity of the ambient air. The cooled air is discharged through the outlet of the cooling channel 7. The water vapor in the air condenses into water droplets and drips down the drip cap into the water guide pipe 63, and then enters the water storage tank 6 through the sponge plug 65. Compared with existing negative ion generators, the negative ion generator of this application has a higher negative ion generation efficiency and produces less ozone. In addition, the air humidity of the negative ion generator of this application can be adjusted by opening and closing the rotating door 62. Furthermore, the negative ion generator of this application is easier to clean.
