Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to an oxygen-making negative oxygen ion generator. Background Art

[0002] Oxygen inhalation therapy is becoming more and more common, and the demand for oxygen generators is also increasing. Through research, it is found that negative oxygen ions can promote the activity of oxygen, thus playing a role in promoting oxygen absorption. Therefore, in order to improve the treatment effect, it can be considered to incorporate negative oxygen ions into the generated oxygen while making oxygen.

[0003] The method of generating negative oxygen ions through natural means is limited by the environment, with low output and difficult to collect. Therefore, artificial preparation of negative oxygen ions has become the main way to obtain negative oxygen ions. At present, there are several methods for artificially generating negative oxygen ions, including corona discharge, thermionic emission of hot metal electrodes or photoelectrodes, radiation of radioactive isotopes, ultraviolet rays, etc.

[0004] However, the above traditional methods will invariably generate substances harmful to the human body, such as ozone, while obtaining negative oxygen ions. Therefore, if the traditional method of preparing negative oxygen ions is applied to an oxygen generator, it may cause harm to the human body during use, resulting in poor safety.

Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are one embodiment of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0036] Embodiment 1

[0037] Please refer to Figures 1 to 6 , Embodiment 1 provides an oxygen-making type negative oxygen ion generator.

[0038] AsFigure 1 As shown, the oxygen - generating negative - oxygen - ion generator includes two parts. One part is the oxygen - making machine main body, and the other part is the negative - oxygen - ion generator 2.

[0039] The oxygen - making machine main body includes an air compressor 11, an air separator 12, an oxygen storage tank 13, and a humidifying bottle 14.

[0040] The air compressor 11 is used to compress air at high density. The air compressor 11 is provided with multiple air outlet pipes 111. The air outlet pipes 111 are connected to the air inlet of the air separator 12. An air solenoid valve 112 is provided on the air outlet pipes 111. The air compressed by the air compressor 11 is output to the air separator 12 through the air outlet pipes 111. In addition, the negative - oxygen - ion generator 2 is also inserted into the air outlet pipes 111.

[0041] The air separator 12 is a closed pressure vessel. Multiple molecular sieve towers 127 are provided inside the air separator 12 to separate nitrogen and oxygen in the compressed air to obtain high - concentration oxygen. The air separator 12 is provided with two air outlets. One of the two air outlets is connected to the oxygen storage tank 13 through an oxygen pipe 122 to transport oxygen to the oxygen storage tank 13 for storage, and an oxygen solenoid valve 123 is provided on the oxygen pipe 122. The other of the two air outlets is connected to an external nitrogen discharge pipe 125 through a nitrogen discharge pipe 124. A nitrogen solenoid valve 126 is provided on the nitrogen discharge pipe 125, and the nitrogen discharge pipe 125 leads to the outside of the room.

[0042] The air outlet of the oxygen storage tank 13 is connected to an oxygen delivery pipe 131. An oxygen concentration sensor 132 for detecting the output oxygen concentration, a filter 133 for filtering oxygen particle impurities, an oxygen flow meter 134 for measuring the oxygen quantity, and an oxygen regulating valve 135 for adjusting the oxygen output are installed on the oxygen delivery pipe 131.

[0043] The oxygen delivery pipe 131 is connected to the humidifying bottle 14. The humidifying bottle 14 is provided with several output oxygen pipes 141, and the output oxygen pipes 141 output oxygen to the outside.

[0044] As Figure 3 shown, the negative - oxygen - ion generator 2 includes a generator 3 and a water bottle 4 installed at the lower part of the generator 3. The generator 3 includes an input pipe 32 for inputting the water in the water bottle 4 into the generator 3 and an insertion pipe 31 inserted into the air outlet pipes 111. The insertion pipe 31 inputs high - pressure gas into the inside of the generator 3 and generates negative pressure. The water is sucked into the inside of the generator 3 through the input pipe 32, is cut and broken by the high - pressure gas to form negative oxygen ions, and the oxygen containing negative oxygen ions is discharged to the outside through the output pipe 33 on the generator 3.

[0045] The oxygen output from the oxygen output pipe 141 and the air flow rich in negative oxygen ions derived from the output pipe 33 are first mixed and then supplied to the user end. In this way, the negative oxygen ions and oxygen can be pre-mixed evenly, thereby improving the quality of the oxygen supplied to the user end.

[0046] As Figure 4 shown, the generator 3 includes a housing 34 installed outside, and an insertion pipe 31 is provided on one side of the housing 34; the water bottle 4 is provided with an upper opening 41, and the input pipe 32 directly passes through the upper opening 41 and is inserted into the interior of the water bottle 4.

[0047] Furthermore, as Figure 4 shown, in this embodiment, both the housing 34 and the water bottle 4 are arc-shaped, and the housing 34 and the water bottle 4 are assembled into a sphere, with a more beautiful shape; furthermore, a decorative part 491 for decoration is also installed at the lower part of the water bottle 4, making it more beautiful. The decorative part 491 sleeves the lower part of the water bottle 4 and has a stable supporting lower part, so that it can be placed separately and play a decorative role. The generator 3 and the water bottle 4 can also be designed into other structures with beautiful shapes, thereby increasing the beauty of the interior.

[0048] As Figure 3 shown, the threaded connection method between the generator 3 and the water bottle 4: an internal thread 341 is provided at the lower part of the housing 34; an external thread 411 is provided on the upper opening 41. The upper opening 41 is inserted into the interior of the housing 34, and the external thread 411 is threadedly connected to the internal thread 341, so that the generator 3 and the water bottle 4 are stably threadedly connected.

[0049] As Figure 4 shown, a vertical liquid inlet part 51 is installed at the upper part of the housing 34. The insertion pipe 31 is on one side of the housing 34, and the insertion pipe 31 is communicated with the housing 34 to input high-pressure gas to the lower part of the housing 34, thereby realizing gas-liquid separation.

[0050] Furthermore, the vertical liquid inlet part 51 and the input pipe 32 are connected through a right-angle connector 52. The input pipe 32 is inserted into the lower end of the right-angle connector 52, and the vertical liquid inlet part 51 is inserted into one side of the right-angle connector 52. The input pipe 32, the right-angle connector 52, and the vertical liquid inlet part 51 present a U-shaped structure, realizing the effect of sucking liquid from the side and flowing out from the middle.

[0051] To achieve the above effect, the input pipe 32 passes through the housing 34 and is inserted into the interior of the water bottle 4 to contact the water inside the water bottle 4; the water in the water bottle 4, under the action of negative pressure, sequentially passes through the input pipe 32, the right-angle connector 52, and the vertical liquid inlet part 51, and flows downward from the end of the vertical liquid inlet part 51.

[0052] As shown Figure 5 in the figure, the upper part of the generator 3 is cylindrical, and a first support plate 71 is fixedly installed inside. The first support plate 71 can be clamped on the cylinder. The first support plate 71 is provided with a first through hole 72, and a vertical water inlet pipe 73 connected to the vertical liquid inlet part 51 is installed inside the first through hole 72. The first support plate 71 is a circular plate, and the first through hole 72 is a circular hole. Further, the diameter of the first through hole 72 is larger than the diameter of the end of the vertical water inlet pipe 73, so an annular outlet 74 is provided between the vertical water inlet pipe 73 and the first through hole 72. The annular outlet 74 is communicated with the insertion pipe 31. The annular outlet 74 ejects high-pressure gas, generating a negative pressure at the end of the vertical water inlet pipe 73, so that the water in the water return bottle 4 sequentially passes through the input pipe 32, the right-angle connector 52, the vertical liquid inlet part 51 and the vertical water inlet pipe 73, and flows vertically downward. The water is cut and broken by the high-speed gas in a circular shape to form negative oxygen ions. A part of the negative oxygen ions is discharged to the outside through the output pipe 33 on the generator 3, and the other part re-condenses into water and returns to the water return bottle 4. In this embodiment, the water can directly flow back vertically.

[0053] Further, as shown Figure 6 in the figure, there is annular high-speed gas around the water column output by the vertical water inlet pipe 73. The annular high-speed gas impacts the water column in a circular shape, tearing, impacting, cutting, and breaking the water molecules, thereby generating more negative oxygen ions and mixing them with each other. The negative oxygen ions produced by the annular high-speed gas cutting, breaking, and tearing the water molecules are multiple times that of the point-like surface impact, and more negative oxygen ions can be generated, resulting in a high concentration of negative oxygen ions output by the output pipe 33. The output pipe 33 outputs negative oxygen ions to the outside.

[0054] As shown Figure 6 in the figure, a second annular inclined surface 731 is provided on the side of the vertical water inlet pipe 73. The second annular inclined surface 731 guides the high-speed gas into the annular outlet 74. The area of the lower port of the second annular inclined surface 731 is much smaller than the area of the upper port, so that when the high-speed gas enters the annular outlet 74, the speed of the high-speed gas can be increased by multiple times.

[0055] In order to guide the direction of the high-speed gas so that the high-speed gas impacts the water column in a directional circular shape, guiding grooves can also be provided on the annular outlet 74 or the second annular inclined surface 731 to adjust the direction of the high-speed gas, which is beneficial to generating more negative oxygen ions.

[0056] In this embodiment, as shown Figure 6As shown, a first annular inclined surface 721 is provided above the first through hole 72. At the same time, an inclined chamfer surface 732 is provided at the end of the vertical water inlet pipe 73. When high-speed gas enters the annular outlet 74, the second annular inclined surface 731 guides the high-speed gas to contract or compress along the inclined surface, and obliquely cuts, impacts, and shatters the water molecules at the end of the vertical water inlet pipe 73 along the first annular inclined surface 721 and the inclined chamfer surface 732, generating more negative oxygen ions. This is better than the above-mentioned ordinary annular impact effect and generates more negative oxygen ions.

[0057] As Figure 5 shown, a second support plate 75 for impact noise reduction is installed below the first support plate 71. The second support plate 75 can be made of a flexible noise reduction material component, thereby reducing the noise generated by the impact of high-speed gas and having a sound insulation effect.

[0058] As Figure 5 shown, an impact filter screen 76 is provided below the second support plate 75. The impact filter screen 76 re-condenses the shattered water mist into water and flows back into the water bottle 4, thereby realizing the recycling of water and ensuring the full utilization of the water resources in the water bottle 4.

[0059] Vertical scale lines are provided on the water bottle 4. By observing the scale lines, users can easily understand the water level in the water bottle 4 to ensure the normal operation of the device at an appropriate water level. When the water level in the water bottle 4 is too low, the threaded connection between the outer housing 34 and the water bottle 4 is opened, the water bottle 4 is taken out, and water is added to the inside of the water bottle 4.

[0060] As Figure 4 shown, a number of U-shaped grooves 77 are also provided around the first support plate 71. The negative oxygen ions below the first support plate 71 enter the upper part of the outer housing 34 through the U-shaped grooves 77. The generator 3 further includes a sealing cover 81 installed on the upper part of the outer housing 34. The sealing cover 81 guides the negative oxygen ions into the output pipe 33 and discharges them to the outside. Among them, the presence of the sealing cover 81 can help prevent substances such as negative oxygen ions or water vapor from escaping from the device and maintain the sealing of the system.

[0061] As Figure 2 shown, a safety valve 82 is also installed on the sealing cover 81. The safety valve 82 is connected to the output pipe 33. The presence of the safety valve 82 is to release excessive gas when the internal pressure of the system rises abnormally to avoid damage to the device due to increased pressure. This is a protection measure to prevent damage to the device or safety hazards caused by excessive pressure.

[0062] The process of generating negative oxygen ions: First, insert the insertion tube 31 into the air outlet pipe 111, input high-pressure gas into the generator 3, and spray it out from the annular outlet 74 to impact the end of the vertical water inlet pipe 73. Thus, under the drive of the high-speed gas, negative pressure is generated. Second, the water in the water bottle 4, under the action of the negative pressure, successively passes through the input pipe 32, the right-angle connector 52, the vertical liquid inlet part 51, and the vertical water inlet pipe 73, and flows vertically downward. Third, the second annular inclined surface 731 guides the high-speed gas to contract or compress along the inclined surface, and obliquely cuts, impacts, and breaks the water molecules at the end of the vertical water inlet pipe 73 along the first annular inclined surface 721 and the inclined chamfer surface 732, thereby generating more negative oxygen ions. Finally, a part of the negative oxygen ions enters the upper part of the outer shell 34 through the U-shaped groove 77, and the sealing cover 81 guides the negative oxygen ions into the output pipe 33 and discharges them to the outside. Another part of the negative oxygen ions moves downward, passes through the noise reduction of the second support plate 75, impacts the filter screen 76 and re-condenses into water, and flows back into the water bottle 4.

[0063] Embodiment 2

[0064] Please refer to Figures 7 to 12 , Embodiment 2 of the present invention provides an oxygen-making negative oxygen ion generator. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0065] As Figure 7 shown, the generator 3 further includes an upper housing 36. The upper housing 36 is cylindrical. One side of the upper housing 36 is provided with an insertion tube 31, and the insertion tube 31 is inserted into the air outlet pipe 111. Further, the generator 3 further includes a lower housing 37 installed below the upper housing 36. The lower housing 37 is also cylindrical and has a U-shaped cross-section. The lower housing 37 seals the generator 3 and also places and guides the water inside the generator 3.

[0066] As Figure 8 shown, the input pipe 32 includes a first right-angle pipe 351 inserted into the water bottle 4, a second right-angle pipe 352 installed on the upper part of the upper housing 36, and a first U-shaped connecting pipe 353 for connecting the first right-angle pipe 351 and the second right-angle pipe 352. One end of the first U-shaped connecting pipe 353 is inserted into the first right-angle pipe 351, and the other end is inserted into the second right-angle pipe 352.

[0067] Under the action of negative pressure, the water in the water bottle 4 successively passes through the first right-angle pipe 351, the first U-shaped connecting pipe 353, and the second right-angle pipe 352 and enters the generator 3, and flows vertically downward.

[0068] Further, sealing members are installed between the first right-angle pipe 351, the first U-shaped connecting pipe 353, and the second right-angle pipe 352 to seal the connection points.

[0069] As Figure 9 shown, in order to fully absorb the water resources in the water bottle 4, a groove 343 is provided at the bottom of the water bottle 4. The groove 343 is at the lowest point of the water bottle 4. The first right-angle pipe 351 is L-shaped, and its end is vertically inserted into the inside of the groove 343 and is connected to the first U-shaped connecting pipe 353 on the side, so that all the water in the water bottle 4 can be sucked dry.

[0070] Furthermore, in order to seal the water bottle 4, a water injection port 49 and a water injection port cap 50 for sealing the water injection port 49 are provided at the top of the water bottle 4; water is added through the water injection port 49, and the water injection port cap 50 blocks or seals the water injection port 49 to prevent water from flowing out of the water injection port 49; furthermore, the water injection port cap 50 is threadedly connected to the water bottle 4 to block or seal the water injection port 49.

[0071] When water needs to be added, the water bottle 4 is horizontally pulled out, so that the independent water bottle 4 is taken out. The sealing cover body is spirally taken out, and then the water injection port rubber plug is vertically pulled out, and water is added through the water injection port 49.

[0072] As Figure 7 shown, a water return member 6 for returning the water inside the generator 3 to the water bottle 4 is connected between the generator 3 and the water bottle 4. Both the input pipe 32 and the water return member 6 are pluggable and connectable to the water bottle 4.

[0073] As Figure 8 shown, the water return member 6 includes a first water return interface 61 installed on the lower housing 37, a second water return interface 62 installed on the water bottle 4, and a second U-shaped connecting pipe 63 for connecting the first water return interface 61 and the second water return interface 62; one end of the second U-shaped connecting pipe 63 is inserted into the first water return interface 61, and the other end is inserted into the second water return interface 62; the water in the generator 3 is collected and temporarily stored through the lower housing 37, and is guided to flow back into the water bottle 4 through the first water return interface 61, the second U-shaped connecting pipe 63, and the second water return interface 62.

[0074] As Figure 8 shown, in order to make the water inlet of the generator 3 and the water return of the water bottle 4 more convenient and smooth, the second water return interface 62 is arranged at the upper part of the water bottle 4, and the first right-angle pipe 351 is arranged at the lower part of the water bottle 4. The second water return interface 62 is higher than the first right-angle pipe 351; there is a certain vertical height difference, which can be clearly seen in Figures 7 to 9 ; in this way, the second water return interface 62 can operate smoothly to return the re-condensed water flow back into the water bottle 4, so as to realize the recycling of water and ensure the full utilization of the water resources in the water bottle 4.

[0075] As Figure 11As shown, in order to collect the water in the generator 3 more quickly, a first inclined plane 38 is provided inside the lower housing 37. The end of the first inclined plane 38 is connected to the first water return interface 61. The re-condensed water moves downward along the first inclined plane 38, guiding the water into the first water return interface 61 and flowing back to the water bottle 4, thus realizing the water return.

[0076] As Figure 10 and Figure 11 shown, a first support plate 71 is installed on the upper housing 36. The first support plate 71 is provided with a first through hole 72. Inside the first through hole 72, a vertical water inlet pipe 73 connected to the second right-angle pipe 352 is installed. Water is vertically output outward inside the vertical water inlet pipe 73. The vertical water inlet pipe 73 is also provided with a number of second through holes 79, which are communicated with the insertion pipe 31. The diameter of the end of the vertical water inlet pipe 73 is smaller than the diameter of the first through hole 72. An annular outlet 74 is formed between the vertical water inlet pipe 73 and the first through hole 72; the annular outlet 74 is communicated with the insertion pipe 31 through the second through holes 79, and high-speed gas is ejected, generating negative pressure at the end of the vertical water inlet pipe 73, so that the water in the water bottle 4 flows downward from the vertical water inlet pipe 73 and is broken into negative oxygen ions by being annularly cut by the high-speed gas. Part of the negative oxygen ions are discharged to the outside through the output pipe 33 on the generator 3, and the other part re-condenses into water and flows back to the water bottle 4 through the first water return interface 61.

[0077] Further, as Figure 12 shown, an annular high-speed gas exists around the water column output by the vertical water inlet pipe 73. The annular high-speed gas impacts the water column annularly, tearing, impacting, cutting, and breaking the water molecules, thus generating more negative oxygen ions; the negative oxygen ions generated by the annular high-speed gas cutting, breaking, and tearing the water molecules are multiple times that of the point-like surface impact, and more negative oxygen ions can be generated, resulting in a high concentration of negative oxygen ions output by the output pipe 33. The output pipe 33 outputs negative oxygen ions to the outside.

[0078] As Figure 12 shown, a second annular inclined surface 731 is provided on the side of the vertical water inlet pipe 73. The second annular inclined surface 731 guides the high-speed gas into the annular outlet 74; the area of the lower port of the second annular inclined surface 731 is much smaller than the area of the upper port, so that when the high-speed gas enters the annular outlet 74, the speed of the high-speed gas can be increased by multiple times.

[0079] In order to guide the direction of the high-speed gas so that the high-speed gas makes a directional annular impact on the water column, guiding grooves can also be provided on the annular outlet 74 or the second annular inclined surface 731 to adjust the direction of the high-speed gas; this is beneficial to generating more negative oxygen ions.

[0080] In this embodiment, as Figure 12 shown, a first annular inclined surface 721 is provided on the upper side of the first through hole 72. At the same time, an inclined chamfer surface 732 is provided at the end of the vertical water inlet pipe 73. When high-speed gas enters the annular outlet 74, the second annular inclined surface 731 guides the high-speed gas to contract or compress along the inclined surface, and obliquely cuts, impacts, and shatters the water molecules at the end of the vertical water inlet pipe 73 along the first annular inclined surface 721 and the inclined chamfer surface 732, thereby generating more negative oxygen ions. This is better than the above-mentioned ordinary annular impact effect and generates more negative oxygen ions.

[0081] The process of generating negative oxygen ions is as follows: First, the insertion tube 31 is inserted into the air outlet pipe 111, and high-pressure gas is input into the generator 3. Specifically, the high-pressure air sequentially passes through the insertion tube 31, the second through hole 79, the second annular inclined surface 731, and the annular outlet 74 to reach the end of the vertical water inlet pipe 73, and impacts the end of the vertical water inlet pipe 73, thereby generating negative pressure at the end of the vertical water inlet pipe 73. Secondly, under the action of the negative pressure, the water in the water bottle 4 sequentially passes through the first right-angle pipe 351, the first U-shaped connecting pipe 353, the second right-angle pipe 352, and the vertical water inlet pipe 73, and flows out from the end of the vertical water inlet pipe 73. Thirdly, the first annular inclined surface 721 and the inclined chamfer surface 732 guide the high-pressure gas to obliquely cut the water molecules at the end of the vertical water inlet pipe 73, and the generated negative oxygen ions are discharged to the outside through the output pipe 33 on the generator 3. Finally, the water in the generator 3 sequentially passes through the first inclined surface 38, the first water return interface 61, the second U-shaped connecting pipe 63, and the second water return interface 62, and flows back into the water bottle 4, thereby realizing the recycling of water and ensuring the full utilization of the water resources in the water bottle 4.

[0082] The water filling process of the water bottle 4: The water bottle 4 is horizontally pulled out, and the water bottle 4 is detachably connected to the first U-shaped connecting pipe 353 and the second U-shaped connecting pipe 63. The water bottle 4 is taken out, and water is added from the water filling port 49.

[0083] The above embodiment is a preferred embodiment of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
