Description

Technical Field

[0001] This utility model relates to the field of negative oxygen ion generation technology, and in particular to a negative oxygen ion generator. Background Technology

[0002] Negative oxygen ions are known as "air vitamins" because they promote metabolism, enhance immunity, have antioxidant and anti-aging effects, eliminate free radicals, and have a calming effect. When patients inhale air or oxygen with a high concentration of ecological-grade negative oxygen ions (more than 10,000 ions / cm3), it can accelerate wound healing and promote early recovery. At the same time, it can also purify indoor air, kill viruses and bacteria, and benefit health.

[0003] Negative oxygen ions are divided into two categories: The first category consists of negative oxygen ions generated in natural environments such as beaches, forests, grasslands, and around waterfalls. These ions have a lifespan of 1 to 20 minutes, are small in particle size, and have high activity. Negative oxygen ions generated by physical impacts such as artificial water jets and air jets also belong to this category. The second category consists of negative oxygen ions generated by corona discharge, radiation, ultraviolet rays, microwaves, etc. These ions have a lifespan of only a few seconds and contain substances harmful to health, such as ozone and nitrogen oxides, and have a significant electrostatic effect. The first category of negative oxygen ions is beneficial to health, while the second category has little or no effect on health and may even be harmful. It is mainly used in industries such as disinfection and sterilization.

[0004] Currently, the mass-produced negative ion generators on the market are corona discharge type negative ion generators, which produce negative ions that have a short lifespan. Another type is the water-jet negative ion generator, which is bulky and generally used in places such as stations, squares, parks, and villas, and cannot be miniaturized. Utility Model Content

[0033] The technical solution of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please refer to Figures 1 to 11 This utility model provides a negative oxygen ion generator.

[0035] like Figure 1 As shown, the negative ion generator includes a generator 1 installed at the top and a water tank 2 installed at the bottom. The water tank 2 is connected to the generator 1 via a siphon tube 16, which introduces water molecules into the generator 1. The generator 1 and the water tank 2 are connected by threads, making it easy to remove the water tank 2 for adding clean water or replacing it. The water tank 2 is equipped with a liquid level indicator or designed to be made of transparent material for easy observation of the water level.

[0036] like Figure 4As shown, the generator 1 includes an outer shell 11 installed on the outside and an inner shell 12 installed inside. The outer shell 11 has an air inlet 13 on one side and an output pipe 14 on the other side. The inner shell 12 is equipped with a generating component 3. The upper part of the generating component 3 is connected to the air inlet 13 through a connecting pipe 15, which is connected to compressed air. The compressed air can be provided by a compressor and connected to the air inlet 13 through a pipe to ensure stable gas input. An input control valve can also be installed on the pipe.

[0037] like Figure 2 As shown, the lower part of the generating component 3 is connected to the water tank 2 via a siphon pipe 16. The siphon pipe 16 introduces water from the water tank 2 into the generating component 3, as shown. Figure 7 As shown, the generating component 3 has a gas-liquid mixing chamber 4 inside. The siphon tube 16 draws water into the gas-liquid mixing chamber 4 and mixes it with compressed air. The lower part of the gas-liquid mixing chamber 4 has an output hole 17. The compressed air input by the connecting pipe 15 impacts the gas-liquid mixing molecules inside the gas-liquid mixing chamber 4 to form negative oxygen ions, which are then sprayed downward from the output hole 17. The negative oxygen ions move upward and are discharged to the outside through the output pipe 14.

[0038] like Figure 7 As shown, the gas-liquid mixing chamber 4 first draws water molecules in from the side via siphon, where they are thoroughly mixed with compressed air to form gas-liquid mixed molecules. These molecules are then accelerated by the impact of compressed air, generating negative oxygen ions under high pressure. These ions are then ejected through the output port 17, forming a mixed airflow of water molecules and negative oxygen ions, evenly distributed within the generating component 3, and discharged to the outside via the output pipe 14. In this embodiment, the output pipe 14 is horizontally positioned; in other embodiments, the output pipe 14 can be designed with an adjustable angle, tilted upwards.

[0039] In other examples, the air inlet 13 may also be designed with a structure similar to the output pipe 14 to adjust the air inlet angle and optimize the air inlet and outlet angles according to actual needs. However, in actual applications, there may be situations where the compressed air pipeline is connected to the output pipe 14. To avoid such situations, the air inlet 13 and the output pipe 14 use different interfaces, such as male and female connectors. The air inlet 13 uses a male connector, and the output pipe 14 uses a female connector. Correspondingly, the compressed air pipeline also uses a female connector. This provides a foolproof function and can completely prevent incorrect connection.

[0040] like Figure 2As shown, the inner shell 12 and outer shell 11 divide the generator 1 into two parts. The upper part of the inner shell 12 and outer shell 11 forms a first chamber 51, and the lower part of the inner shell 12 and outer shell 11 forms a second chamber 52. The first chamber 51 and the second chamber 52 are connected by a plurality of connecting holes 86 on the inner shell 12. The negative oxygen ions are generated in the second chamber 52, reach the first chamber 51 through the connecting holes 86, and are discharged to the outside through the output pipe 14. The number and distribution of the connecting holes 86 are optimized according to actual needs to ensure efficient transmission of negative oxygen ions. The inner shell 12 and outer shell 11 are made of corrosion-resistant materials to extend the service life of the equipment and improve the overall operational stability. Furthermore, the design of the connecting holes 86 takes into account aerodynamic principles to ensure smooth airflow, reduce resistance, and improve the transmission efficiency of negative oxygen ions.

[0041] Furthermore, such as Figure 4 As shown, the inner shell 12 includes a first mounting plate 83 connected to the outer shell 11 and a second mounting plate 84 connected to the connecting pipe 15; the first mounting plate 83 and the second mounting plate 84 are connected by a first annular cavity plate 85, and the connecting hole 86 is provided on the first annular cavity plate 85.

[0042] like Figure 7 As shown, the lower part of the generating component 3 is provided with a first insertion hole 31 and a horizontal output pipe 32. In this embodiment, the first insertion hole 31 is configured to be inserted into one siphon pipe 16. In other embodiments, the first insertion hole 31 can be designed to have multiple insertion holes so as to be inserted into multiple siphon pipes 16, thereby achieving multiple water inlets. The horizontal output pipe 32 is connected to the first insertion hole 31 to ensure uniform water flow distribution and improve siphon efficiency.

[0043] like Figure 7 As shown, the horizontal output pipe 32 is located on one side of the gas-liquid mixing chamber 4, above the output hole 17; the lower end of the first insertion hole 31 is connected to the siphon pipe 16, and the upper end is connected to the horizontal output pipe 32; the end of the horizontal output pipe 32 away from the first insertion hole 31 is connected to the gas-liquid mixing chamber 4, and water molecules are introduced into the gas-liquid mixing chamber 4.

[0044] In other embodiments: the horizontal output pipe 32 can be configured as a ring to achieve annular water inlet, surrounding and communicating with the gas-liquid mixing chamber 4, thus introducing water molecules into the gas-liquid mixing chamber 4. The annular design of the horizontal output pipe 32 enhances the uniform distribution of water molecules within the gas-liquid mixing chamber 4, improving the generation efficiency of negative oxygen ions. Furthermore, the annular structure effectively avoids dead zones in the water flow, ensuring sufficient gas-liquid mixing and further optimizing the overall performance of the equipment.

[0045] like Figure 10As shown, to further accelerate the compressed air and create a siphon and negative pressure effect, the gas-liquid mixing chamber 4 is provided with a first conical inclined surface 41. The upper part of the first conical inclined surface 41 is connected to the connecting pipe 15, and the lower part is connected to the output port 17. The first conical inclined surface 41 guides the compressed air to accelerate; increasing the speed of the compressed air also increases the degree of mixing between the gas and liquid, which is beneficial for generating more negative oxygen ions. To introduce water molecules into the gas-liquid mixing chamber 4, the horizontal output pipe 32 is set on the first conical inclined surface 41 to ensure that the water molecules are fully mixed with the accelerated compressed air.

[0046] Furthermore, the gas-liquid mixing chamber 4 is provided with a first conical inclined surface 41, which can guide the gas-liquid mixed molecules downward to enhance the guiding effect and increase the amount of negative oxygen ions generated.

[0047] Furthermore, a turbulence structure can be provided on the first conical inclined surface 41 to enhance the gas-liquid mixing effect. The turbulence structure consists of multiple staggered protrusions to further optimize the gas-liquid mixing effect.

[0048] like Figure 10 As shown, the generating component 3 is internally equipped with a connecting component 7, which is mounted on the gas-liquid mixing chamber 4. The connecting component 7 has a third conical inclined surface 74 inside, used to increase the velocity of compressed air. The third conical inclined surface 74 cooperates with the first conical inclined surface 41 to form a dual acceleration effect, further improving the gas-liquid mixing efficiency. Specifically, the upper part of the third conical inclined surface 74 is connected to the connecting pipe 15, and the lower part of the third conical inclined surface 74 has a fourth through hole 75 communicating with the gas-liquid mixing chamber 4, inputting compressed air into the gas-liquid mixing chamber 4; thus achieving communication between the compressed air and the interior of the gas-liquid mixing chamber 4.

[0049] like Figure 8 As shown, the connecting component 7 includes a first circular flange 71 at the upper end, a vertical direct contact portion 72 at the middle end, and a second conical inclined surface 73 at the lower end; during installation, the connecting component 7 is fixed inside the generating component 3; specifically, as shown... Figure 7 As shown, the first circular flange 71 is mounted on the first frustum 33 inside the generating component 3, the vertical direct contact portion 72 is mounted on the vertical mounting portion 34 inside the generating component 3, and the second conical inclined surface 73 is adapted to the first conical inclined surface 41 on the gas-liquid mixing chamber 4; the first circular flange 71 also contacts the lower end of the connecting pipe 15, fixing the connecting component 7 inside the generating component 3.

[0050] like Figure 3As shown, the second mounting plate 84 is equipped with a second annular cavity plate 81 at its lower part. The second annular cavity plate 81 and the lower part of the connecting pipe 15 form a first receiving cavity 82. The upper end of the generating component 3 is inserted into the first receiving cavity 82 to achieve connection and also fix the connecting component 7.

[0051] like Figure 5 As shown, the water tank 2 is provided with an upper connecting part 21, and the siphon tube 16 is inserted into the water tank 2; the lower part of the outer shell 11 is provided with an internal thread 23; the upper connecting part 21 is provided with an external thread 22, and the upper connecting part 21 is inserted into the lower part of the outer shell 11 to achieve a threaded connection; thus facilitating disassembly and water addition; in order to achieve a better sealing effect, a second sealing ring 62 is installed between the first mounting plate 83 and the upper connecting part 21.

[0052] like Figure 4 As shown, the connecting pipe 15 is L-shaped. One end of the connecting pipe 15 is connected to the air inlet 13 and fixedly connected to the outer shell 11, and the other end is fixedly connected to the second mounting plate 84. The connecting pipe 15 and the outer shell 11 can be integrally formed or fixed together by laser welding.

[0053] like Figure 4 As shown, in order to make the connection with the compressor tighter, the air inlet 13 is equipped with a first sealing ring 61.

[0054] like Figure 1 As shown, in order to limit the position of the first sealing ring 61, a side cover 66 is installed on the outer side of the outer shell 11. The side cover 66 is installed in the first receiving groove 67 on the outer shell 11 by screws. The side cover 66 is installed on one side of the first sealing ring 61 to limit the position of the first sealing ring 61. The design of the side cover 66 can enhance the stability of the first sealing ring 61 and ensure that it will not shift.

[0055] like Figure 1 As shown, in order to connect with the compressor, the side cover 66 is provided with a first through hole 68, which passes through the first sealing ring 61 and connects with the air inlet 13.

[0056] like Figure 4As shown, the lower part of the generating component 3 is also fitted with a mounting cover 9. The mounting cover 9 is provided with several second through holes 91 adapted to the siphon tube 16. The siphon tube 16 passes through the second through holes 91 and is inserted into the first insertion hole 31. The middle part of the mounting cover 9 is provided with a third through hole 92 adapted to the output hole 17. The diameter of the third through hole 92 is larger than the diameter of the output hole 17. The negative oxygen ions are sprayed downwards from the output hole 17 and the third through hole 92 in sequence to form a uniform negative oxygen ion airflow. Other negative oxygen ion airflows or water molecules can also flow out from the excess second through holes 91. The negative oxygen ions diffuse upwards, and the water molecules move downwards and flow back into the water tank 2 to form a cycle.

[0057] like Figure 6 and Figure 11 As shown, to achieve the snap-fit ​​installation of the mounting cover 9, the lower part of the generating component 3 is provided with a second receiving cavity 93, and the mounting cover 9 is provided with a circular insertion part 94 that inserts into the second receiving cavity 93; the circular insertion part 94 is provided with a plurality of conical receiving parts 95, and the second receiving cavity 93 is provided with conical insertion parts 96 for inserting into the conical receiving parts 95. The conical insertion parts 96 and the conical receiving parts 95 cooperate with each other to achieve the snap-fit ​​between the generating component 3 and the mounting cover 9. Both the mounting cover 9 and the generating component 3 are made of plastic material to ensure that the mounting cover 9 fits tightly with the generating component 3.

[0058] To minimize noise from the generator, a buffer component can be installed at the bottom of the generator 1. This buffer component is made of rubber and can effectively absorb vibrations and reduce noise. The buffer component is designed in an arc shape to increase the efficiency of water molecule reflux.

[0059] In other embodiments, a noise-silencing component may also be installed to reduce noise interference and improve the user experience.

[0060] The steps for using the negative oxygen ion generator are as follows:

[0061] Step S1: The generator 1 is connected to the compressor through the air inlet 13, and compressed air is input into the generator 1;

[0062] Step S2: The compressed air enters the gas-liquid mixing chamber 4 through the air inlet 13, connecting pipe 15 and connecting component 7 in sequence. The compressed air is accelerated by the third conical inclined surface 74 and the first conical inclined surface 41, which creates a siphon effect on one end of the horizontal output pipe 32, causing water molecules in the water tank 2 to enter the gas-liquid mixing chamber 4 through the siphon pipe 16 and mix fully with the compressed air to form a gas-liquid mixture.

[0063] Step S3: The mixed gas-liquid mixture is accelerated by compressed air to form negative oxygen ions, which are then ejected downwards from the output hole 17 and the third through hole 92 in sequence.

[0064] Step S4: The negative oxygen ions move upward and reach the first chamber 51 through the connecting hole 86, and are discharged to the outside through the output pipe 14; the negative oxygen ions diffuse evenly in the air, improving the environmental quality; excess water molecules flow back to the water tank 2.

[0065] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
