[0079] The following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. Similar component numbers in the drawings represent similar components. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0080] It should be understood that when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, wholes, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or their combinations.

[0081] It should also be understood that the terms used in the specification of the embodiments of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present utility model. As used in the specification of the embodiments of the present utility model and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are intended to include the plural forms.

[0082] Please refer to Figures 1-4 As shown, an air purification device 10 is provided in an embodiment of the present utility model, including: a housing 100, a negative oxygen ion generation unit 200, a power unit 300, a sound insulation unit 400, and a second fluid source unit 500. The housing 100 has a receiving cavity, and the housing 100 is provided with an outlet 110 and an inlet 120; the negative oxygen ion generation unit 200 is disposed in the receiving cavity, and the negative oxygen ion generation unit 200 is used for making the inflowing fluids interact to generate negative oxygen ions and releasing the negative oxygen ions to the space to be purified through the outlet 110; the power unit 300 is disposed in the receiving cavity, the power unit 300 has an air outlet end and an air inlet end, the air outlet end is connected to the negative oxygen ion generation unit 200, and the power unit 300 is used for conveying the first fluid containing oxygen to the negative oxygen ion generation unit 200; the sound insulation unit 400 is disposed in the receiving cavity, the sound insulation unit 400 has a sound insulation channel, the sound insulation channel is communicated between the air inlet end and the inlet, and the sound insulation unit 400 is used for sound insulation of the first fluid flowing in from the inlet 120; the second fluid unit is disposed in the receiving cavity and is connected to the negative oxygen ion generation unit 200, and the second fluid unit is used for providing the second fluid containing releasable electrons to the negative oxygen ion generation unit 200.

[0083] In the above embodiment, the first fluid can be any fluid containing oxygen, and the present utility model makes no limitation here. As an example, the first fluid can be air or oxygen.

[0084] The second fluid may be a liquid containing electrons that can be released. As an example, the second fluid is water, and the way for the water to release electrons may be a method well-known in the art. For example, by simulating the scenario of water flow hitting at a waterfall in nature in the negative oxygen ion generation unit 200, the water is sheared due to the violent impact to generate free electrons, and the electrons combine with oxygen molecules in the first fluid to form negative oxygen ions, and the negative oxygen ions are released from the exhaust port 212 of the negative oxygen ion generation unit 200 and the outlet 110 of the housing 100 to the space to be purified. By generating negative oxygen ions by using the impact force, the ozone content in the negative oxygen ions generated in this way will be relatively low, thus helping to protect people's physical health; and there will be no accompanying electron radiation, which can further protect people's physical health.

[0085] In the air purification device 10 provided by the embodiment of the present invention, the first fluid containing oxygen enters the sound absorption channel of the sound absorption unit 400 through the inlet 120, which can reduce the noise of the first fluid entering the air purification device 10, and the noise of the first fluid after passing through the sound absorption channel and being transported by the power unit 300 to the negative oxygen ion generation unit 200 will also be reduced. In this way, the purpose of reducing the working noise of the air purification device 10 can be achieved, and there is no need to externally connect an air source device, and the purpose of conveniently moving the air purification device 10 can also be achieved.

[0086] For the convenience of assembly, the structure of the housing 100 can be further optimized. Please continue to refer to Figure 1 As shown, in some embodiments, the housing 100 includes a top plate 150, a first housing 130, and a second housing 140. The top plate 150, the first housing 130, and the second housing 140 are detachably connected in the vertical direction. It can be understood that in the vertical direction, the top plate 150 is located at the top of the first housing 130, and the first housing 130 can be above the second housing 140. The detachable connection can be any detachable connection method well-known in the art, such as snap connection.

[0087] The first housing 130 has a first accommodation cavity, the second housing 140 has a second accommodation cavity, the negative oxygen ion generation unit 200, the power unit 300, and the sound absorption unit 400 are arranged in the first accommodation cavity, the second fluid source unit 500 is arranged in the second accommodation cavity, and the inlet 120 and the outlet 110 can both be located on the first housing 130, or on the second housing 140, or respectively on the first housing 130 and the second housing 140.

[0088] In the above embodiments, the shapes and materials of the first housing 130 and the second housing 140 can be selected according to actual application requirements. Exemplarily, in order to facilitate the movement of the air purification device 10, it is necessary to reduce the weights of the first housing 130 and the second housing 140. Therefore, the materials of the first housing 130 and the second housing 140 can be selected as any materials that can reduce their weights. For example, the materials of the first housing 130 and the second housing 140 can be aluminum or its alloys, plastics, etc. The shapes of the first housing 130 and the second housing 140 can be a cuboid, a cube, an ellipsoid, a cylinder, etc. In some examples, the shapes of the first housing 130 and the second housing 140 can be cylinders.

[0089] In addition, the housing 100 may further include a support base 160, and the diameter of the support base 160 is greater than the diameter of the housing 100 connected thereto, so that the air purification device 10 can be stably erected on the ground or other horizontal surfaces.

[0090] Further, in some examples, pulleys can be installed at the bottom of the support base 160, so as to facilitate the movement of the air purification device 10.

[0091] In the air purification device 10 provided by the present utility model, the negative oxygen ion generation unit 200 is configured to cause the inflowing fluid to interact to generate negative oxygen ions, and release the negative oxygen ions to the space to be purified through the outlet 110. The negative oxygen ion generation unit 200 can be any device well known in the art for manufacturing negative oxygen ions.

[0092] Please refer to Figure 5As shown, in some embodiments, the negative oxygen ion generation unit 200 includes a main body, an impact member 220, a first pipeline, and a second pipeline. The main body has a generation chamber for generating negative oxygen ions, as well as a first inlet 211, a second inlet 231, and an exhaust port 212 that communicate with the generation chamber. Among them, the first inlet 211 is connected to the first pipeline, the second inlet 231 is connected to the second pipeline, and the exhaust port 212 is communicated with the outlet 110 of the housing 100; the impact member 220 is disposed in the generation chamber. The second fluid flows into the generation chamber through the second pipeline and the second inlet 231, and the first fluid is shot at the impact member 220 through the first pipeline and the first inlet 211. In this way, it can drive the second fluid in the generation chamber to continuously impact the impact member 220, and then can simulate the scene of water flow impact at a waterfall in nature. The water is sheared due to the violent impact to generate free electrons, and the electrons combine with oxygen molecules in the first fluid to generate negative oxygen ions. The negative oxygen ions are released from the exhaust port 212 of the negative oxygen ion generation unit 200 and the outlet 110 of the housing 100 to the space to be purified. Therefore, in the process of generating negative oxygen ions by the above negative oxygen ion generation unit 200, there will be no hazards of radioactivity and high-energy radiation, thus improving the safety of negative oxygen ion generation. In addition, the above negative oxygen ion generation unit 200 has a simple structure, and negative oxygen ions can be generated by driving the second fluid to impact the impact member 220 by the first fluid, reducing the generation cost of negative oxygen ions.

[0093] In the above embodiments, the main body can be made of metal materials, such as stainless steel and aluminum alloy, and is formed by processes such as die-casting, cutting, or injection molding, so that the main body has strong impact resistance. Further, to ensure the strength of the main body, the main body can be manufactured by an integral molding process, or several separately formed parts can be assembled by welding or screwing to facilitate processing. The impact member 220 can be formed of materials with higher hardness such as metal and ceramic, and its shape can be spherical, plate-shaped, or columnar, etc. When the impact member 220 and the main body are made of the same material, the two can also be made by an integral molding process.

[0094] Please continue to refer to Figure 5 As shown, in some embodiments, the main body includes a first main body 210 and a second main body 230. The impact member 220, the generation chamber, the first inlet 211, and the exhaust port 212 are all disposed in the first main body 210. The first main body 210 is located inside the second main body 230, and its generation chamber communicates with the inner cavity of the second main body 230. The second main body 230 is also connected to the second fluid source unit 500, and the second fluid flows into the generation chamber of the first main body 210 through the second main body 230.

[0095] In some embodiments, the negative oxygen ion generation unit 200 further includes a liquid level gauge 240, which is disposed in the second main body 230 and is used to detect the liquid level in the second main body 230.

[0096] In order to further improve the degree of automatic control of the air purification device 10, in some embodiments, the air purification device 10 further includes a control panel 600 and a controller 700. The control panel 600 and the controller 700 are electrically connected and are disposed on the top plate 150 of the housing 100. The controller 700 is disposed on the outer side or the top surface of the housing 100 and is electrically connected to the negative oxygen ion generation unit 200, the power unit 300, and the second fluid source unit 500 respectively. Through the above control panel 600 and controller 700, the automatic control of the negative oxygen ion generation unit 200, the power unit 300, and the second fluid source unit 500 can be realized, so as to automatically provide the first fluid source, the second fluid source, and generate and release negative oxygen ions.

[0097] In some specific embodiments, the liquid level gauge 240 is electrically connected to the controller 700. When the liquid level gauge 240 detects that the liquid level in the generation chamber is in a low water level state, the liquid level gauge 240 sends an infusion instruction to the controller 700. At this time, the control panel 600 controls the second fluid source unit 500 to be turned on through the controller 700, and conveys the second fluid into the generation chamber until the liquid level in the generation chamber reaches the normal liquid level. Then, the liquid level gauge 240 sends a closing instruction to the controller 700, and the controller 700 controls the second fluid source unit 500.

[0098] In some embodiments, the air purification device 10 further includes a disinfection device 250, which is disposed on the second body 230. The disinfection device 250 is used to sterilize the negative oxygen ion generation unit 200, effectively preventing bacteria from breeding inside the second body 230 and keeping the second fluid inside the second body 230 clean.

[0099] In the above embodiments, the disinfection device 250 can be any device having a sterilization and disinfection function, such as a disinfection lamp or the like.

[0100] In the air purification device 10 provided by the present utility model, the power unit 300 can convey the first fluid entering the sound absorption unit 400 from the inlet 120 into the negative oxygen ion generation unit 200. In this way, there is no need to connect an additional air source device, which improves the integration degree of the air purification device 10 and also facilitates the movement of the air purification device 10.

[0101] Please refer to Figure 6 As shown, in some embodiments, the power unit 300 includes a housing 310 and a compressor 320. The air outlet end and the air inlet end are located on the housing 310; the compressor 320 is disposed inside the housing 310. The compressor 320 has an air inlet and an air outlet. The air inlet of the compressor 320 is communicated with the air inlet end, and the air outlet of the compressor 320 is communicated with the air outlet end. By wrapping the compressor 320 with the housing 310, the amount of noise emitted by the compressor 320 to the outside of the housing 310 during operation can be reduced.

[0102] To further reduce the noise generated when the compressor 320 operates, the structure of the housing 310 can be further improved. In some embodiments, the housing 310 includes a housing body and a sound insulation layer, and the compressor 320 is located inside the housing body; the sound insulation layer is disposed between the inner wall of the housing body and the compressor 320. By providing a sound insulation layer between the inner wall of the housing body and the compressor 320, the noise generated by the compressor 320 can be further reduced, thereby helping to reduce the noise generated when the air purification device 10 operates.

[0103] In the above embodiments, the material of the housing body can be a well-known high-strength material in the art, such as metal and plastic. The material of the sound insulation layer can also be any material with sound insulation function in the art, such as sound insulation cotton. Further, the sound insulation layer can be attached to the inner wall of the housing shell.

[0104] In addition, the power unit 300 can also be further improved to reduce the noise generated by the compressor 320. In some embodiments, the power unit 300 further includes a shock absorber 330 connected between the compressor 320 and the inner wall of the housing 310. Through this shock absorber 330, the noise generated by the vibration of the compressor 320 during operation can be reduced.

[0105] In some specific embodiments, the shock absorber 330 includes any one or more of a rubber pad, a silica gel pad, or a rubber spring pad.

[0106] In other embodiments, the power unit 300 further includes a hook 340 and a silica gel ring. The hook 340 is fixed to the inner wall of the housing 310; the silica gel ring is connected between the hook 340 and the compressor 320. Connecting the compressor 320 and the housing 310 through the hook 340 and the silica gel ring can reduce the swing amplitude of the compressor 320 during operation, and further reduce the noise generated when the compressor 320 operates.

[0107] Further, in the power unit 300, selecting a suitable type of compressor 320 can also help reduce the noise generated during the operation of the power unit 300. In some embodiments, the compressor 320 can be a DC compressor 320. Further, the compressor 320 can be a variable-speed DC compressor 320, and a speed control board 321 for adjusting the speed of the DC compressor 320 is provided on the outer side of the housing 310, so that the flow rate of the compressed air can be driven and controlled, which helps to further reduce the noise generated when the air purification device 10 operates.

[0108] In addition, the above-mentioned compressor 320 can be a micro-compressor 320, for example, a compressor 320 with a length * width * height of 90mm * 45mm * 70mm, which can reduce its volume, and thus help to reduce the volume and weight of the air purification device 10, facilitating its movement and portability.

[0109] In the above embodiment, when the compressor 320 works for a long time, the temperature inside the housing 310 will rise. At this time, it is necessary to timely stabilize the temperature within a suitable range, which can help to improve the service life of the compressor 320 and enable the air purification device 10 to work properly for a long time.

[0110] In some embodiments, the power unit 300 further includes a heat dissipation component, which is arranged on the housing 310. Through this heat dissipation component, the heat generated by the compressor 320 can be discharged in time, so that its working temperature is maintained within the normal temperature range.

[0111] In the embodiment of the present utility model, the heat dissipation component can be a fan. In some specific embodiments, the heat dissipation component can be a scroll fan 350, which is fixed on the outer wall of the housing 310. The noise generated during its operation is relatively low, so it helps to reduce the noise generated by the operation of the air purification device 10. In addition, an exhaust part 351 is provided on the sound insulation unit 400, and the exhaust part 351 is used to divert the hot air flow discharged by the scroll fan 350 into the sound insulation unit 400 as the first fluid.

[0112] In the above embodiment, the size of the scroll fan 350 can be selected according to actual application requirements. In a specific embodiment, the size of the scroll fan 350 is 50mm * 50mm * 15mm.

[0113] In the air purification device 10 provided in the embodiment of the present utility model, the sound insulation unit 400 has a sound insulation channel, and the sound insulation channel is communicated between the air inlet end and the inlet 120. The sound insulation unit 400 is used to insulate the first fluid flowing in from the inlet 120. In some embodiments, the sound insulation unit 400 includes a cavity and a partition 430. The cavity has a first chamber and a second chamber. The cavity is also provided with a first opening 411 communicating with the first chamber and a second opening communicating with the second chamber. The first opening 411 is connected to the air inlet end, and the second opening is connected to the inlet 120; the partition 430 is arranged between the first chamber and the second chamber, and the partition 430 is provided with a third opening; wherein, the first opening 411, the first chamber, the third opening, the second chamber and the second opening are communicated to form a sound insulation channel. The setting of the double-layer chamber can extend the movement path of the first fluid, weaken the noise generated by it, and thus achieve sound insulation.

[0114] In a specific embodiment, the cavity includes a first cavity 410 and a second cavity 420. A partition 430 is located between the first cavity 410 and the second cavity 420. Among them, the first cavity 410 has a first chamber, and the second cavity 420 has a second chamber.

[0115] In the above embodiment, the number of chambers in the cavity can be designed according to actual application requirements, and is not limited to two chambers. It can also be set to three chambers, four chambers, etc. Further, multiple chambers can be arranged in the radial direction of the cavity, or can be arranged in the vertical direction.

[0116] The number of the first openings 411 can be designed according to actual requirements. For example, the number of the first openings 411 can be 2, 3, or 4. The above first openings 411 can be connected to the air inlet end through pipeline connectors such as threaded straight-through pipes and silicone hoses.

[0117] In some embodiments, the cavity and the partition 430 can be made by an integral molding process, which makes the structure of the sound absorption unit 400 simple, convenient for disassembly, and has high space utilization rate.

[0118] To further enhance the sound absorption effect of the sound absorption unit 400, in some embodiments, the sound absorption unit 400 further includes a sound absorption layer disposed on the inner wall of the cavity and / or the surface of the partition 430. Through the sound absorption layer, the noise when the first fluid flows into the negative oxygen ion generation unit 200 can be further reduced, thereby helping to further reduce the noise when the air purification device 10 works.

[0119] In the embodiments of the present utility model, the material of the sound absorption layer can be any material well-known in the art having a sound absorption function. Exemplarily, the material of the sound absorption layer can include sound absorption cotton.

[0120] In some embodiments, the air purification device 10 further includes a jet ejector disposed at the outlet 110 and connected to the negative oxygen ion generation unit 200. The jet ejector is used to release the negative oxygen ions generated by the negative oxygen ion generation unit 200 into the space to be purified. The jet ejector can effectively mix negative ions and oxygen to form an oxygen source with negative oxygen ions. After the oxygen source is released into the space to be purified, it can not only purify the surrounding air, but also increase the oxygen concentration in the environment, creating an oxygen-rich environment, which is beneficial to people's physical health.

[0121] In some embodiments, the second fluid source unit 500 includes a first container 510 and a supply assembly. The first container 510 is disposed in the accommodation cavity. A second pipeline is connected between the first container 510 and the negative oxygen ion generation unit 200. The first container 510 is used to store a second fluid containing electrons that can be released. The supply assembly is disposed in the second pipeline. The supply assembly includes a pump 520 and / or a second switch, wherein the second switch is used to control the on / off of the second pipeline. Through the first container 510, the second pipeline and the supply assembly, the second fluid source can be automatically provided.

[0122] Further, the first container 510 is snap-connected to the inner wall of the accommodation cavity, which can reduce the occurrence of shaking of the first container 510.

[0123] In the above embodiments, both the material and shape of the first container 510 can be selected according to application requirements. Exemplarily, the material of the first container 510 can be a plastic material. Specifically, the plastic material can be polyethylene terephthalate (PET), which can further reduce the weight of the air purification device 10 and facilitate its movement. The shape of the first container 510 can be a cuboid or a cylinder.

[0124] In some embodiments, the air purification device 10 further includes a third pipeline and a third switch 530. The third pipeline is connected between the first container 510 and the negative oxygen ion generation unit 200. The third switch 530 is disposed in the third pipeline, and the third switch 530 is used to control the on / off of the third pipeline. The setting of the above third pipeline and the third switch 530 can contribute to the recycling of the fluid source and the cleaning of the negative oxygen ion generation unit 200.

[0125] In some examples, the third switch 530 can include a solenoid valve.

[0126] The use of the air purification device 10 of the present utility model will be described in detail below.

[0127] Take out the first container 510, fill it with water, and place it in the second housing 140 with a buckle for fixation. After connecting the power supply through the power interface 800, start the air purification device 10 through the control panel 600. At this time, the controller 700 can detect the liquid level inside through the liquid level gauge 240 in the negative oxygen ion generation unit 200. If the liquid level is lower than the lowest liquid level line, the controller 700 controls the pump 520 to open and supplement the liquid until the liquid level is higher than the highest liquid level, and then the controller 700 controls the pump 520 to close and opens the compressor 320 to introduce air into the negative oxygen ion generation unit 200. At this time, the negative oxygen ion generation unit 200 works, and it can be clearly felt that negative oxygen ions are released through the outlet 110 of the first housing 130.

[0128] When the air purification device 10 has been working for a period of time (usually about 2 months), drainage operation is required. At this time, the water in the first container 510 needs to be emptied first, and then the drainage solenoid valve is opened through the control panel 600 and the controller 700. The water in the negative ion generation unit 200 flows back to the first container 510 through the solenoid valve. After the drainage operation is completed, the controller 700 is used to control the drainage solenoid valve to close.

[0129] During the above-mentioned liquid replenishment and drainage processes, the sterilization lamp in the negative ion generation unit 200 can be turned on through the control panel 600 and the controller 700 for ultraviolet disinfection and sterilization treatment to effectively prevent bacteria from breeding.
