[0002] In existing technologies, negative ion generators often utilize the principle of air-induced generation, which involves using high-pressure air to impact a liquid, thereby producing negative ions. Current negative ion generators mainly consist of a generator and an air compressor, with the compressor providing a stable, high-speed airflow to the generator.

[0003] Indoor air quality is generally poor, and opening windows for ventilation is often the only way to improve it. However, opening windows can lower the indoor temperature and allow outside dust to enter, which can be harmful to people with weak respiratory systems and affect their health. Furthermore, when negative ion therapy or maintenance is needed, it's difficult to provide sufficient negative ions at home, making it hard to receive timely treatment. Therefore, providing a cabinet-style negative ion generator for indoor use is essential and can significantly improve indoor air quality.

[0065] Optionally, water can be replenished from the water storage device 241, or the water in the water storage device 241 can be replenished manually. Furthermore, the compressor 1 can also be located inside the control box 2, with the water storage device 241 located above the water supply pipeline 24, thus facilitating water replenishment.

[0066] In use, the compressor supplies high-pressure air to the negative ion generator 3 through the air supply pipe; the water storage device 241 supplies water to the negative ion generator 3; the pure water inside the negative ion generator 3 is cut and broken by the high-pressure air to form negative ions; the negative ions are discharged to the outside through the negative ion generator 3, which can provide sufficient negative ions; there are at least two negative ion generators 3, and both are supplied with gas by the compressor and water by the control box, so that multiple negative ion generators can provide negative ions simultaneously and continuously. Moreover, the above structure can be adapted to be placed in building facilities. This invention can be combined with various building facilities to form an environment with sufficient negative ions, which is conducive to centralized control and centralized water supply and drainage. The system is free from cleaning, greatly simplifies daily maintenance, and is more conducive to improving indoor air quality.

[0067] It should be noted that the water storage device 241 is usually located at the bottom of the control box 2, while the controller 22 and the pipeline connection area are located at the top of the water storage device 241.

[0068] Based on the above embodiments, please refer to Figure 1 and Figure 2 The control box 2 specifically includes:

[0069] The housing 21 is equipped with an air inlet 211, an air outlet 212, a water outlet 213, a water return outlet 214, and a controller 22;

[0070] The gas supply pipeline 23 is connected to the air inlet 211 and the air outlet 212 at both ends, respectively. The air outlet 212 is used to connect to the negative oxygen ion generator 3, and the air inlet 211 is connected to the air outlet of the compressor, so that the compressor can supply gas to the negative oxygen ion generator 3 through the gas supply pipeline 23 in the control box 2.

[0071] The water supply pipeline 24 is connected at one end to the water storage device 241 and at the other end to the water outlet 213.

[0072] Optionally, the housing 21 is provided with three sections, including a lower space, an upper left space above the lower space, and an upper right space. The upper left space is for the controller 22, which contains electrical control circuits, core processing devices, etc. The upper right space is used for the connection and conversion parts of various pipelines, including an air inlet 211, an air outlet 212, a water outlet 213, and a water return outlet 214. The lower space is used for water storage or water treatment, which contains a bottled water or tap water purification filtration device.

[0073] In this embodiment, both the gas supply pipeline 23 and the water supply pipeline 24 are located inside the housing 21. This allows the compressor to supply gas to the control box 2, which in turn receives high-pressure gas and supplies water via an internal water storage device 241 to the negative ion generators 3. In other words, the negative ion generators 3 can be entirely supplied with gas and liquid by the control box 2. This design integrates the compressor and control box 2, enabling it to supply water and gas to multiple independently installed negative ion generators 3. When applied to different scenarios, this creates a modular and integrated installation method. For example, in a building or facility, only one compressor and control box structure can be provided, and multiple negative ion generators 3 can be installed within the building or facility. These can be surface-mounted or concealed in walls or ceilings, similar to the setup of a single outdoor unit and multiple internal pipelines in a central air conditioning system. This structure combines surface and concealed wiring, adaptable to various applicable environments.

[0074] Optionally, the above structure also includes a return water pipe 25, one end of which is connected to the return water inlet 214 and the other end is connected to the return water storage device 251, which is disposed in the box 21.

[0075] Based on any of the above embodiments, the gas pipeline 23 is provided with a pressure gauge 231, a pressure regulating valve 232, a gas flow meter 234, a first electric valve 235 and a gas pressure gauge 236 in sequence along the direction from the gas inlet 211 to the gas outlet 212.

[0076] The pressure gauge 231, pressure regulating valve 232, air flow meter 234, first electric valve 235 and air pressure gauge 236 are all connected to the controller 22. The controller 22 adjusts the opening or closing or opening degree of the first electric valve 235 according to the detection data of the pressure gauge 231.

[0077] Optionally, the flow rate of the gas supply line 23 can be constant or adjusted according to the usage conditions, such as continuously outputting a certain flow rate and a certain pressure, or outputting a certain flow rate value at a certain pressure. The gas circuit control in the gas supply line 23 includes a pressure gauge 231 and a flow meter 234. Optionally, a manual valve can also be installed for manual assistance.

[0078] The gas pipeline 23 is a power-controlled pipeline used to deliver high-pressure gas to the outlet of the control box 2. The controller 22 inside the control box 2 controls the gas pressure and flow rate.

[0081] The controller 22 is used to control the first electric valve 235 and the second electric valve 243.

[0082] It should be noted that the second electric valve 243 installed on the water supply pipeline 24 is used to control the opening and closing of the water supply pipeline 24. Usually, the water pump 242 and the second electric valve 243 are opened or closed simultaneously.

[0083] The water pressure gauge 245 detects the pressure in the pipeline, and the pressure sensor 244 is used for detection and display. It can be installed outside the housing 21 for display. In addition, the manual valve 237 can be installed in a position that can be operated by external personnel to control the opening and closing of the water supply pipeline 24 in special circumstances.

[0084] Optionally, the number of water storage devices 241 in the above embodiments can be two or more.

[0085] When the workspace is relatively large, the negative ion generator may correspond to a large number of nozzles. Considering the large number of negative ion generators or the losses in the pipeline, the water storage device 241 may not be enough. Therefore, the number of water storage devices 241 can be adjusted according to the actual situation.

[0086] Based on any of the above embodiments, a manual return water valve 252 is provided on the return water pipeline 25, and a second water level sensor 253 is provided on the return water storage device 251, the second water level sensor 253 being connected to the controller 22.

[0087] The control method involves the controller 22 receiving information when the water level in the return water storage device 251 exceeds a preset level. This information is then used for alarm purposes or for control of other locations in the water circuit, thereby preventing the water level in the return water storage device 251 from exceeding the limit. Optionally, for example, it can control the closure of the fourth electric valve 254 installed on the return water pipeline.

[0088] Based on any of the above embodiments, it also includes a water supply storage tank 27, which is connected to the water outlet 213 of the control box 3 and is connected to a plurality of negative ion generators 3 through a plurality of water supply pipes. The water supply pipes are equipped with a third electric valve 272 for controlling the supply of water to the plurality of negative ion generators 3.

[0089] The water supply storage tank 27 is equipped with a first water level sensor 271 for measuring the internal water level, and the first water level sensor 271 is electrically connected to the controller 22.

[0090] The controller 22 is used to control the opening and closing or the opening degree of the second electric valve 243 and the third electric valve 372 according to the detection result of the first water level sensor 271.

[0091] Based on any of the above embodiments, at least two of the negative ion generators 3 have their return water ends connected to the return water inlet 214 of the control box 2 via return water pipelines. The return water pipelines are equipped with a fourth electric valve 254 for controlling the on / off state or flow rate of the return water pipelines. The fourth electric valve 254 is electrically connected to a controller 22, and the controller 22 is used to control the opening and closing or the opening degree of the fourth electric valve 254 according to the detection data of the second water level sensor 253.

[0092] The controller controls the opening and closing state of the fourth electric valve 254 to be opposite to that of the third electric valve 272.

[0093] It should be noted that the purpose of the fourth electric valve 254 being in the opposite open / closed state to the third electric valve 272 is to meet the usage requirements. For example, when the third electric valve 272 is open and the fourth electric valve 254 is closed, it is in use, allowing water to flow to the negative ion generator 3 and form negative ions.

[0094] When the third electric valve 272 is closed and the fourth electric valve 254 is opened, the water in the pipeline flows back to the return water storage device 251.

Each of the two or more bottled water devices is connected to the water supply pipeline. The water supply pipeline is equipped with control valves for controlling the water supply or shutdown of different bottled water devices.
