[0034] 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.

[0035] Please refer to Figures 1 to 13 This utility model provides a negative oxygen ion generating device.

[0036] like Figure 1 As shown, the generating device includes a generating device body 5. The generating device body 5 includes a generator 1 installed at the top for generating negative oxygen ions and a water tank 2 installed at the bottom for supplying water. The generator 1 includes a housing 11, which generates negative oxygen ions inside. The housing 11 has a connection port 12 for connecting compressed air on one side, a downwardly extending extension 13 at the bottom, and an upwardly extending air outlet 14 at the top for outputting negative oxygen ions.

[0037] like Figure 3 and Figure 8 As shown, the extension 13 is used to connect with the water tank 2. Specifically, the extension 13 and the water tank 2 are horizontally inserted into each other. The extension 13 is provided with a horizontally arranged inlet 131 and a return outlet 132. The inlet 131 is inserted into the water tank 2 to input the water inside the water tank 2 into the generator 1, where it is impacted by the compressed air input from the connection port 12 to generate negative oxygen ions. The return outlet 132 is inserted into the water tank 2 to return the water inside the generator 1 to the water tank 2.

[0038] When water tank 2 and generator 1 are plugged into each other, the assembly of water tank 2 and generator 1 is realized, and water tank 2 and generator 1 are fixed together. As long as water tank 2 is not driven to move horizontally, they will not separate, thus realizing the fixation of water tank 2 and generator 1.

[0039] Furthermore, such as Figure 7 As shown, the extension 13 is provided with several fixing structures 3 for fixing the generator 1. Each fixing structure 3 is a stepped connecting hole on the extension 13, and a connecting bolt for fixing the generator 1 is installed inside the stepped connecting hole. The connecting bolt passes through the stepped connecting hole to fix the generator 1, and can be fixed to a wall or connected to the connecting frame 4. Figure 6 As shown, the connecting frame 4 has threaded holes for connecting bolts. The threaded holes correspond to the connecting bolts and are arranged vertically, thereby fixing the generator 1 and the connecting frame 4 together.

[0040] Furthermore, the generating device body 5 also includes a connecting frame 4 installed outside the water tank 2; the connecting frame 4 is connected together by threaded holes and connecting bolts, such as... Figure 2 As shown, the water tank 2 is horizontally inserted into the connecting frame 4. The upper part of the connecting frame 4 is provided with an insertion groove 41. The extension 13 is vertically inserted into the connecting frame 4 through the insertion groove 41, thereby horizontally connecting with the horizontally inserted water tank 2. The lower part of the connecting frame 4 is provided with a fixing groove 42. The fixing groove 42 is equipped with fixing bolts for fixing the connecting frame 4. The fixing bolts pass through the fixing groove 42 to fix the connecting frame 4 to the wall.

[0041] Furthermore, in order to facilitate the fixing of the connecting frame 4, the fixing groove 42 is a vertical waist-shaped groove, which facilitates the adjustment of the vertical height of the connecting frame 4.

[0042] like Figures 6 to 9 As shown, in order to accurately position the generator 1, the extension 13 has U-shaped protrusions 134 on both sides, and the connecting frame 4 has a corresponding U-shaped groove 43. The U-shaped protrusions 134 are inserted into the U-shaped groove 43. The extension 13 also has cylindrical protrusions 135 on both sides, and the connecting frame 4 has a corresponding circular insertion hole 44. The cylindrical protrusions 135 are inserted into the circular insertion hole 44.

[0043] like Figure 11As shown, the water tank 2 includes an upper cover 21 installed at the top and a lower bucket 22 installed at the bottom. A handle groove 23 is provided at the connection between the upper cover 21 and the lower bucket 22, so as to facilitate the disconnection of the water tank 2 from the extension 13. A water filling hole 25 is also provided on the upper part of the upper cover 21. A plastic cap 24 is covered on the water filling hole 25. One end of the water filling hole 25 is hinged to the plastic cap 24, and the other end is provided with an opening groove 26 for opening the plastic cap 24.

[0044] When water tank 2 needs to be added, use the handle groove 23 to pull water tank 2 horizontally open, separating it from generator 1 and also from connecting frame 4; use the opening groove 26 to open plastic cover 24, as... Figure 11 As shown, water is added through the water inlet 25.

[0045] To facilitate the insertion of the water tank 2 and the generator 1, an insertion guide 27 is provided on one side of the upper cover 21, and an insertion groove 136 is provided between the water inlet 131 and the water outlet 132. The insertion guide 27 is inserted into the insertion groove 136 to guide the water inlet 131 and the water outlet 132 into the water tank 2.

[0046] To facilitate sealing between the water tank 2 and the generator 1, double sealing rings 137 are provided at the ends of the water inlet 131 and the water outlet 132; Figure 11 As shown, the return water inlet 132 directly returns water without requiring an additional connecting water pipe; the inlet 131 needs to be connected to an additional connecting water pipe in order to draw water from the bottom of the water tank 2 and send it into the generator 1.

[0047] like Figure 11As shown, the generator 1 also includes a vertical water pipe 15 connected to the water inlet 131, a U-shaped generating tank 16 installed at the lower part of the connecting port 12, a guide ring 17 installed inside the U-shaped generating tank 16, and a generating ring 18 installed at the lower part of the guide ring 17; the middle part of the guide ring 17 is connected to the vertical water pipe 15, allowing the water in the water inlet 131 to flow vertically downwards into the generator 1, and an output protrusion 172 is provided at its end; the circumference of the guide ring 17 is provided with several first connecting holes 171 connected to the connecting port 12; the first connecting holes 171 are used to input compressed air; the middle part of the generating ring 18 is provided with a first through hole 181, into which the output protrusion 172 is inserted. In the first through hole 181, a high-speed airflow annular outlet 182 connected to the connection port 12 is provided between the output protrusion 172 and the first through hole 181. The high-speed airflow annular outlet 182 sprays out compressed air, generating negative pressure at the end of the output protrusion 172, so that the water in the water tank 2 passes through the inlet 131, the vertical water pipe 15 and the output protrusion 172 in sequence, and flows vertically downward. It is cut and broken by the high-speed airflow annularly to form negative oxygen ions. Some of the negative oxygen ions move downward and are restricted by the outer shell 11, and then move upward. They are discharged to the outside through the fifth connecting hole 166 on the side of the U-shaped generating barrel 16 and the air outlet 14. The other part re-condenses into water and flows back to the water outlet 132.

[0048] Furthermore, such as Figure 13 As shown, the water column output by the output protrusion 172 is surrounded by a ring-shaped high-speed airflow. The ring-shaped high-speed airflow impacts the water column in a ring, tearing, impacting, cutting, and shattering the water molecules, so that the airflow and water molecules are fully mixed, thereby generating more negative oxygen ions. The negative oxygen ions produced by the ring-shaped high-speed airflow cutting, shattering, and tearing the water molecules are many times greater than those produced by point-area impact, which can generate more negative oxygen ions, resulting in a high concentration of negative oxygen ions output from the air outlet 14.

[0049] Furthermore, such as Figure 13 As shown, the first through hole 181 has an annular inclined slope on its side, which guides the high-speed airflow into the high-speed airflow annular outlet 182. The area of ​​the lower port of the annular inclined slope is much smaller than the area of ​​the upper port, so that when the high-speed airflow enters the high-speed airflow annular outlet 182, the speed of the high-speed airflow can be increased many times, which is conducive to generating more negative oxygen ions.

[0050] In order to reduce the noise generated by negative oxygen ions and make them more fine and eliminate water mist, a first noise reduction plate 183 for impact noise reduction is installed at the lower part of the generating ring 18. The first noise reduction plate 183 has a second connecting hole 184 on its side. The first noise reduction plate 183 is made of flexible noise reduction material, thereby reducing the noise generated by the impact of high-speed airflow and having a silent effect.

[0051] Below the first noise reduction plate 183, there is an impact filter 185. The impact filter 185 re-condenses the broken water mist into water, which flows back into the return water inlet 132, thereby eliminating the water mist contained in the negative oxygen ions and realizing the recycling of water.

[0052] Negative oxygen ions move downwards and disperse, passing through the first noise reduction plate 183, the second connecting hole 184, and the impact filter 185 to reach the space between the U-shaped generating barrel 16 and the outer shell 11. When they encounter the restriction of the outer shell 11, they move upwards and are discharged to the outside through the fifth connecting hole 166 on the side of the U-shaped generating barrel 16 and the air outlet 14. Another part is re-condensed into water and flows back to the return water outlet 132.

[0053] To reduce noise more effectively and make the system quieter, a second noise reduction plate 186 for impact noise reduction is installed at the lower part of the impact filter 185. The second noise reduction plate 186 is also made of flexible noise reduction material, thereby reducing the noise generated by the impact of high-speed airflow and having a quieting effect.

[0054] A cover plate 19 is installed between the outer shell 11 and the air outlet 14. The cover plate 19 is connected to the inside of the outer shell 11. The cover plate 19 concentrates the negative oxygen ions on the side of the U-shaped generating barrel 16, and the water mist re-condenses into water, which flows downward back into the return water inlet 132. The cover plate 19 is provided with a third connecting hole 191. One end of the third connecting hole 191 is connected to the fifth connecting hole 166 on the side of the U-shaped generating barrel 16, and the other end is connected to the air outlet 14.

[0055] like Figure 12 and 13 As shown, the negative oxygen ions are generated at the end of the output protrusion 172, move downwards and disperse around, pass through the first noise reduction plate 183, the second connecting hole 184 and the impact filter 185 to reach the space between the U-shaped generating barrel 16 and the outer shell 11. When the outer shell 11 restricts them, they move upwards and pass through the fifth connecting hole 166 on the side of the U-shaped generating barrel 16 to reach the lower part of the cover plate 19. They are then concentrated through the third connecting hole 191 and discharged to the outside through the air outlet 14.

[0056] 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.
