[0002] In the prior art, negative oxygen ion generating equipment often uses the principle of air excitation to generate negative oxygen ions, that is, using high-pressure air to impact liquid to generate negative oxygen ions. The existing negative oxygen ion generating equipment is mainly composed of a generator, an air compressor, and a water bottle that supplies water to the generator. The high-pressure air input by the air compressor impacts and tears up the liquid transported by the water bottle in the generator, thereby generating negative oxygen ions.

[0003] Generally, a negative oxygen ion generating device is equipped with a separate air compressor, which makes the entire negative oxygen ion generating device large in size, heavy, and occupies a large space. When the negative oxygen ion concentration in the room needs to be increased, the large negative oxygen ion generating device needs to be placed indoors, and the transportation steps are relatively cumbersome. Therefore, in order to overcome the above difficulties, the generator and the water bottle are generally integrated together to reduce the volume. However, when water needs to be added, the generator and the water bottle need to be taken out together, and then the generator and the water bottle need to be separated before water can be added to the water bottle. In this way, the water adding process is complicated, requires strong hands-on ability, and the water adding time is also long. It also needs to be separated and disassembled, which is prone to disassembly failures, thereby increasing the failure rate and affecting customer experience. Utility Model Content

[0028] The following will be combined with the drawings in this embodiment of the utility model to clearly and completely describe the technical solution in this embodiment of the utility model. Obviously, the described embodiment is one embodiment of the utility model, not all embodiments of the utility model. Based on this embodiment of the utility model, all other embodiments of the utility model obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the prior art, Figure 1As shown, the device body 1 includes a generator 3 and a water bottle 4 installed at the lower part of the generator 3; the bottom of the generator 3 is provided with an internal thread 98, and the upper part of the water bottle 4 is provided with an external thread 99. The generator 3 and the water bottle 4 are connected together by threads, and the two are not independent of each other, and it is inconvenient to separate the two. When adding water, the generator 3 and the water bottle 4 need to be taken out together, and the water bottle 4 needs to be rotated to take out, and then water is added, which makes the process of taking out the water bottle 4 and the process of adding water very cumbersome.

[0030] In this embodiment, if Figure 3 As shown, the device body 1 includes a generator 3 and a water bottle 4 installed at the lower part of the generator 3; the generator 3 and the water bottle 4 are independent of each other and can be separated; thus, the water bottle 4 can be easily taken out and separated from the generator 3 later.

[0031] Since water circulation is required between the generator 3 and the water bottle 4, the generator 3 and the water bottle 4 still need to be connected by a pipeline; specifically, a water inlet component 5 and a water return component 6 are connected between the generator 3 and the water bottle 4, and the water inlet component 5 transports the water in the water bottle 4 to the generator 3; the water return component 6 returns the water in the generator 3 to the water bottle 4, thereby realizing water circulation, which is beneficial to saving water and reducing the consumption rate of water in the water bottle 4.

[0032] However, in order to facilitate the rapid removal and insertion of the water bottle 4, the water inlet assembly 5 and the water return assembly 6 are both plug-in connected to the water bottle 4; the water bottle 4 can be directly and quickly pulled out from the water inlet assembly 5 and the water return assembly 6, and during installation, it can also be quickly inserted and directly fixed, and a quick-plug connector in the prior art can be used, so that insertion and removal are fast and convenient; further, in this embodiment, the water bottle 4 is pulled out horizontally, and if an optimized design is performed, it can also be pulled out vertically.

[0033] like Figure 2 As shown, an external gas source 2 is installed on one side of the device body 1, and the external gas source 2 is used to store and provide high-pressure air. The external gas source 2 is connected to a plurality of high-pressure output ports 22 through a delivery air pipe 21, and the high-pressure output ports 22 are used for high-pressure air output. A control valve 23 is also installed at one end of the plurality of output ports 22 connected to the delivery air pipe 21, and the control valve 23 is used to control the output pressure and output shutoff. The control valve 23 can be a combination of a pressure regulating valve and a pressure gauge, which is used to display pressure and adjust output pressure; it can also be a separate shut-off valve, which is used for shutoff.

[0034] Furthermore, the external gas source 2, the high-pressure output port 22, the air delivery pipe 21 and the control valve 23 can all be hidden, and only the output port 22 can be seen. The output port 22 adopts a quick connection port, which is convenient for quick insertion and connection. The high-pressure air is output to the inserted component, and the existing quick connection port can be used.

[0035] like Figure 3 As shown, the generator 3 includes an insertion tube 31 arranged on one side, and the insertion tube 31 is inserted into the high-pressure output port 22 to achieve a stable connection with the high-pressure output port 22, and input high-pressure air into the generator 3. The high-speed impact of the high-pressure air generates a negative pressure inside the generator 3. Under the action of the negative pressure, the water inlet component 5 directly sucks water into the generator 3, which is cut and crushed by the high-pressure air to form negative oxygen ions. A part of the negative oxygen ions is discharged to the outside through the output tube 33 on the generator 3, and the other part is re-condensed into water and flows back to the water bottle 4 through the return water component 6.

[0036] The negative pressure causes the water inlet assembly 5 to transport the water in the water bottle 4 to the generator 3; after the impact is completed, the water flows back from the generator 3 to the water bottle 4 through the water return assembly 6 under the action of gravity, thereby realizing water circulation.

[0037] Furthermore, the water bottle 4 can also use centralized water supply, just like the centralized gas supply of the external gas source 2. The water bottle 4 is placed independently and has a large volume, which can be infinite, so as to supply multiple generators 3 for use. At the same time, the water inlet component 5 and the water return component 6 are also matched therewith, and their lengths can be lengthened, and the internal pipelines can also be more complicated. As long as the water inlet supply and water return are completed, the first U-shaped connecting pipe 53 of the water inlet component 5 and the second U-shaped connecting pipe 63 of the water return component 6 can be hidden; only the second right-angle pipe 52 and the first water return interface 61 need to be reserved to realize the water supply and water return of the generator 3.

[0038] Furthermore, in the present embodiment, centralized gas supply and shared gas source are realized; centralized water supply and centralized water return are also realized; thus, the device can be inserted at any time and used at any time without considering gas supply and water supply problems, thereby reducing the number of times of adding water or realizing automatic water adding, so that the water bottle 4 can be removed, further reducing the number of parts of the device body 1, thereby reducing the volume and facilitating carrying.

[0039] like Figure 6 As shown, the generator 3 also includes an upper shell 32, which is cylindrical. An insertion tube 31 is provided on one side of the upper shell 32, and the insertion tube 31 is inserted into the high-pressure output port 22; further, the generator 3 also includes a lower shell 34 installed below the upper shell 32, and the lower shell 34 is also cylindrical and has a U-shaped cross-section. The lower shell 34 seals the generator 3 and also places and guides the water inside the generator 3.

[0040] like Figure 4As shown, the water inlet assembly 5 includes a first right-angle tube 51 inserted into the water bottle 4, a second right-angle tube 52 installed on the upper part of the upper shell 32, and a first U-shaped connecting tube 53 for connecting the first right-angle tube 51 and the second right-angle tube 52; one end of the first U-shaped connecting tube 53 is plugged into the first right-angle tube 51, and the other end is plugged into the second right-angle tube 52; under the action of negative pressure, the water in the water bottle 4 passes through the first right-angle tube 51, the first U-shaped connecting tube 53 and the second right-angle tube 52 in turn into the interior of the generator 3, and flows out vertically downward; further, a sealing member is installed between the first right-angle tube 51, the first U-shaped connecting tube 53 and the second right-angle tube 52 to seal the connection.

[0041] like Figure 4 As shown, the water return assembly 6 includes a first water return interface 61 installed on the lower shell 34, 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 plugged into the first water return interface 61, and the other end is plugged into the second water return interface 62; the water in the generator 3 is collected and temporarily stored through the lower shell 34, 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.

[0042] like Figure 4 As 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 tube 51 is arranged at the lower part of the water bottle 4, and the second water return interface 62 is higher than the first right-angle tube 51; there is a certain vertical height difference, Figure 4 and Figure 5 In this way, the second water return interface 62 can operate smoothly, and the re-condensed water flows back to the water bottle 4, thereby realizing the recycling of water and ensuring that the water resources in the water bottle 4 are fully utilized.

[0043] like Figure 7 As shown, in order to collect the water in the generator 3 more quickly, a first inclined surface 35 is provided inside the lower shell 34, and the end of the first inclined surface 35 is connected to the first water return interface 61. The recondensed water moves downward along the first inclined surface 35, guiding the water into the first water return interface 61 and flowing back to the water bottle 4, thereby realizing the reflux of water.

[0044] Further, such as Figure 5 As shown, in order to fully absorb the water resources in the water bottle 4, a groove 43 is provided at the bottom of the water bottle 4, and the groove 43 is at the lowest point of the water bottle 4. The first right-angle tube 51 is L-shaped, and the end is vertically inserted into the groove 43, and the side is connected to the first U-shaped connecting tube 53, so that all the water in the water bottle 4 can be sucked dry.

[0045] Furthermore, in order to seal the water bottle 4, a water filling port 49 and a water filling port bottle cap 50 for sealing the water filling port 49 are provided on the top of the water bottle 4; water is added from the water filling port 49, and the water filling port bottle cap 50 blocks or seals the water filling port 49 to prevent water from flowing out of the water filling port 49; further, the water filling port bottle cap 50 is threadedly connected to the water bottle 4, thereby blocking or sealing the water filling port 49.

[0046] When water needs to be added, the water bottle 4 is pulled out horizontally, thereby taking out the independent water bottle 4, the sealing cover body is screwed out, and then the water filling port plug is pulled out vertically, and water is added from the water filling port 49.

[0047] like Figure 6 As shown, the upper shell 32 is provided with a first support plate 71, the first support plate 71 is provided with a first through hole 72, the first through hole 72 is provided with a vertical water inlet pipe 73 connected to the second right-angle tube 52, the vertical water inlet pipe 73 outputs water vertically outward, the vertical water inlet pipe 73 is further provided with a plurality of second through holes 79, the second through holes 79 are connected to the insertion tube 31, the diameter of the end of the vertical water inlet pipe 73 is smaller than the diameter of the first through hole 72, and the vertical water inlet pipe A high-speed airflow annular outlet 74 is formed between 73 and the first through hole 72; the high-speed airflow annular outlet 74 is connected to the insertion tube 31 through the second through hole 79, and the high-speed airflow is ejected to generate 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 cut and broken by the high-speed airflow annularly 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 is re-condensed into water and flows back to the water bottle 4 through the first return water interface 61.

[0048] like Figure 8 As shown, the side of the vertical water inlet pipe 73 is provided with a second annular inclined surface 731, and the second annular inclined surface 731 guides the high-speed airflow to enter the high-speed airflow annular outlet 74; the upper side of the first through hole 72 is provided with a first annular inclined surface 721, and the end of the vertical water inlet pipe 73 is provided with an inclined chamfered surface 732. Before the high-speed airflow enters the high-speed airflow annular outlet 74, it is compressed by the second annular inclined surface 731 to increase the airflow speed, and the water molecules at the end of the vertical water inlet pipe 73 are cut obliquely, impacted, and crushed along the first annular inclined surface 721 and the inclined chamfered surface 732, so as to fully mix the airflow and water molecules and produce more negative oxygen ions. The effect is better than the above-mentioned ordinary annular impact, and more negative oxygen ions are produced.

[0049] like Figure 7As shown, a second support plate 75 for impact noise reduction is installed at the lower part of the first support plate 71. The second support plate 75 can be made of flexible noise reduction material components, thereby reducing the noise generated by the impact of high-speed airflow and having a silent effect.

[0050] like Figure 7 As shown, an impact filter 76 is provided under the second support plate 75. The impact filter 76 condenses the crushed water mist into water again and flows it back into the water bottle 4, thereby realizing the recycling of water and ensuring that the water resources in the water bottle 4 are fully utilized.

[0051] like Figure 6 As shown, the generator 3 also includes a sealing cover 81 installed on the upper part of the upper shell 32, and the sealing cover 81 is vertically inserted into the upper shell 32 to guide the negative oxygen ions into the output pipe 33 and discharged to the outside, and the output pipe 33 is connected to the sealing cover 81 through a universal joint; wherein, the presence of the sealing cover 81 can help prevent negative oxygen ions or water vapor and other substances from escaping from the equipment, and maintain the closedness of the system; the sealing cover 81, the upper shell 32 and the lower shell 34 form a sealed body.

[0052] The sealing cover 81 is also provided with a safety valve 82, which is connected to the output pipe 33. The safety valve 82 is provided to release excessive gas when the internal air pressure of the system increases abnormally, so as to prevent the equipment from being damaged due to the increase in air pressure. This is a protective measure to prevent equipment damage or safety hazards caused by excessive pressure.

Specifically, the high-pressure air passes through the insertion tube 31, the second through hole 79, the second annular inclined surface 731 and the high-speed airflow annular outlet 74 in sequence 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;

[0055] Secondly, under the action of negative pressure, the water in the water bottle 4 passes through the first right-angle tube 51, the first U-shaped connecting tube 53, the second right-angle tube 52 and the vertical water inlet pipe 73 in sequence, and flows out from the end of the vertical water inlet pipe 73;

[0056] Again, the first annular inclined surface 721 and the inclined chamfered surface 732 guide the high-pressure air to cut the water molecules at the end of the vertical water inlet pipe 73 obliquely, and the generated negative oxygen ions are discharged to the outside through the output pipe 33 on the generator 3;

[0057] Finally, the water in the generator 3 flows back to the water bottle 4 through the first inclined surface 35, the first return water interface 61, the second U-shaped connecting pipe 63 and the second return water interface 62 in sequence, thereby realizing the recycling of water and ensuring that the water resources in the water bottle 4 are fully utilized.

[0058] The water adding process of the water bottle 4 is as follows: the water bottle 4 is pulled out horizontally, the water bottle 4 is connected with the first U-shaped connecting tube 53 and the second U-shaped connecting tube 63 by plugging and unplugging, the water bottle 4 is taken out, and water is added from the water filling port 49 .
