[0020] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0021] Reference Figure 1~Figure 4, which is an embodiment of the present invention, proposes a dispersing device for negative ion self-suspending coating processing, which is used to disperse the negative ion flow generated by the negative ion generator, including: a first main body 1, having an air flow channel 110, the air flow channel 110 has a feed port 1061 and a discharge port 109, the feed port 1061 is connected to the air flow channel 110 and the negative ion generator, the first main body 1 has a spiral flow channel 103, the spiral flow channel 103 has a plurality of air inlets 107 arranged at intervals, the air inlet 107 is connected to the air flow channel 110, and the air inlet 107 is used to introduce air flow that transports the negative ion flow into the air flow channel 110; a dispersing nozzle 5, which is arranged at the discharge port 109, and the dispersing nozzle 5 is connected to the air flow channel 110; a rotating body 2, which is rotatably arranged in the dispersing nozzle 5, and a spraying channel 4 is provided between the rotating body 2 and the dispersing nozzle 5, and the spraying channel 4 is connected to the air flow channel 110.

[0022] In the above scheme, the negative ion flow generated by the negative ion generator can smoothly enter the air flow channel 110 through the feed port 1061. In the actual operation process, the function of the air inlet 107 is to introduce the air flow that transports the negative ion flow into the air flow channel 110. The air flow entering through the air inlet 107 can be fully mixed with the negative ion flow in the air flow channel 110. A dispersion nozzle 5 is provided at the discharge port 109, and the dispersion nozzle 5 is kept in a connected state with the air flow channel 110. A rotating body 2 is rotatably provided inside the dispersion nozzle 5, and a spraying channel 4 is formed between the rotating body 2 and the dispersion nozzle 5, and the spraying channel 4 is also connected with the air flow channel 110.

[0023] The negative ion generator starts to work and produces a negative ion flow. At the same time, the air flow enters the air flow channel 110 continuously through the air inlet 107 on the spiral flow channel 103. The air flow and the negative ion flow are mixed in the air flow channel 110 in an all-round way. The air flow can be mixed with the negative ion flow at a tangent angle, so that the negative ion flow is more evenly distributed under the drive of the air flow. The mixed air flow continues to flow to the discharge port 109 and arrives at the dispersion nozzle 5. In the dispersion nozzle 5, the rotating body 2 is in a rotating state, and the spray channel 4 between it and the dispersion nozzle 5 performs the final dispersion treatment on the mixed air flow. The rotation of the rotating body 2 can produce a certain centrifugal force and turbulence effect, so that the mixed air flow can be more evenly and stably dispersed to form a stable negative ion flow. This stable negative ion flow can better apply the negative ion self-suspending coating technology in the working process of the air purifier, and form a uniform and stable coating on the surface of key components such as the filter element of the air purifier. After the envelope is formed, when air passes through, it can effectively adsorb and remove harmful substances such as PM2.5, formaldehyde, benzene, etc. in the air, providing users with a clean and healthy air environment.

[0024] When manufacturing water purifier filter elements in the field of water treatment, the whole process is similar to the field of air purification, but it also has its own special features. After the negative ion generator generates a negative ion flow, the air flow also enters the air flow channel 110 through the air inlet 107 of the spiral flow channel 103 to mix with the negative ion flow. In this process, due to the characteristics of negative ions and the mixing effect with the air flow, negative ions can better interact with pollutants in the water. The mixed airflow reaches the dispersion nozzle 5, and after being dispersed through the spray channel 4 between the rotating body 2 and the dispersion nozzle 5, a stable negative ion flow is formed. In the manufacturing process of the water purifier filter element, this stable negative ion flow helps to form a uniform and stable capsule on the surface of the filter element material. When water containing harmful substances such as heavy metals, bacteria, viruses, etc. passes through the filter element, the capsule can effectively remove these harmful substances in the water through a variety of action mechanisms such as ion exchange and adsorption, thereby ensuring the safety and health of drinking water.

[0025] When manufacturing medical devices or health products in the field of health care, the negative ion flow generated by the negative ion generator is mixed with the air flow entering the air flow channel 110 through the air inlet 107. In terms of medical devices, for example, in the process of forming a coating on the surface of some therapeutic instruments, the mixed airflow is dispersed by the dispersion nozzle 5 to form a stable negative ion flow, thereby forming a uniform and stable coating on the surface of the instrument. This coating can release negative ions when in contact with the human body or during the operation of the instrument, which has a positive impact on human health, such as improving immunity, promoting blood circulation, relieving fatigue, etc. For the manufacture of health products, such as some oral or external health products, the negative ion flow participates in the coating process. After the coating is formed on the carrier surface of the health product, negative ions can be slowly released during use, which plays a role in improving human health.

[0026] The dispersing device for negative ion self-suspending coating processing of the present invention can effectively overcome the defects of traditional negative ion coating processing technology, give full play to the advantages of negative ion self-suspending coating technology, and provide strong support for product manufacturing and performance improvement in various fields, whether in the fields of air purification, water treatment or medical care.

[0027] Working process: First, the negative ion generator starts working and generates a negative ion flow. Since the negative ion generator is connected to the feed port 1061 of the air flow channel 110 of the first main body 1, the generated negative ion flow will smoothly enter the air flow channel 110 inside the first main body 1 through the feed port 1061. A spiral flow channel 103 is provided on the first main body 1, and the spiral flow channel 103 has a plurality of air inlets 107 arranged at intervals, and these air inlets 107 are connected to the air flow channel 110. The external air flow will enter the air flow channel 110 through these air inlets 107. The air flow entering from different air inlets 107 meets the negative ion flow in the air flow channel 110. Since the air inlets 107 are arranged at intervals, the air flow can be mixed with the negative ion flow at different positions, thereby achieving a more comprehensive and uniform preliminary mixing. Compared with the traditional method of directly ejecting negative ions, this mixing method can better control the stability of the negative ion flow. The mixture of the negative ion flow and the air flow that have been preliminarily mixed continues to flow toward the discharge port 109 in the air flow channel 110. The air flow channel 110 provides a stable transmission path for the mixed air flow, ensuring that the mixed air flow can move in an orderly manner. The mixed air flow reaches the dispersion nozzle 5 at the discharge port 109. The rotor 2 is rotatably arranged in the dispersion nozzle 5, and there is a spray channel 4 between the rotor 2 and the dispersion nozzle 5, and the spray channel 4 is connected to the air flow channel 110. When the mixed air flow enters the dispersion nozzle 5, the rotation of the rotor 2 generates centrifugal force, and this centrifugal force will pull the mixed air flow to the surroundings, so that the distribution of the mixed air flow in the spray channel 4 is more uniform. At the same time, the rotation of the rotor 2 will also produce a certain turbulence effect in the spray channel 4, further disrupting the possible unevenness of the mixed air flow, and prompting the mixed air flow to be more finely dispersed.

[0028] Since the spray channel 4 is connected to the air flow channel 110, the mixed air flow dispersed by the rotating body 2 can be sprayed from the dispersion nozzle 5 in a more stable and uniform state, forming a stable negative ion flow. This stable negative ion flow plays a key role in ensuring the effectiveness of the negative ion self-suspended coating technology in various application fields.

[0029] Furthermore, the first main body 1 includes: a mixing tube 101, having a first spiral groove 1032, and the air inlet holes 107 are all arranged on the first spiral groove 1032; a wrapping piece 102, which is covered on the outer wall of the mixing tube 101, and the wrapping piece 102 has a second spiral groove 1031 corresponding to the first spiral groove 1032, and the first spiral groove 1032 and the second spiral groove 1031 together constitute a closed spiral flow channel 103.

[0030] In the above scheme, in the first main body 1 structure of the dispersion device for processing the negative ion self-suspended coating, the mixing tube 101 is a space for mixing airflow, the air inlet holes 107 are all located on the first spiral groove 1032, and a plurality of air inlet holes 107 are also arranged in a spiral shape. The air inlet holes 107 can guide the air flow to enter the air flow channel 110 in the mixing tube 101 in an orderly manner along a spiral trajectory. Compared with the traditional straight hole air intake method, the air inlet holes 107 on the spiral groove allow the incoming air flow to interact with the negative ion flow in a more complex and effective manner, and can be mixed at different angles and positions, thereby improving the mixing uniformity and sufficiency. The second spiral groove 1031 on the package 102 corresponds to the first spiral groove 1032 of the mixing tube 101, and the two together form a closed spiral flow channel 103, which separates the closed spiral flow channel 103 into the first spiral groove 1032 and the second spiral groove 1031, which is not only convenient for the early processing and production of the spiral flow channel 103, but also convenient for the later cleaning of the spiral flow channel 103. Secondly, on the one hand, the spiral flow channel 103 can better control the flow path and flow rate of the air flow, avoid air flow leakage and disordered diffusion, and make the air flow accurately enter the mixing tube 101 and mix with the negative ion flow as required; on the other hand, it enhances the interaction between the negative ion flow and the air flow, increases the collision and mixing opportunities between the two to improve the mixing efficiency and quality; in addition, the closed structure can also reduce the interference of external factors on the internal air flow, and ensure the stability of the mixing of the negative ion flow and the air flow under different environments.

[0031] Furthermore, the wrapping member 102 has an air inlet channel 105 , the axis of the air inlet channel 105 is tangent to the mixing tube 101 , the air inlet channel 105 is connected to the spiral flow channel 103 , and the air inlet channel 105 is externally connected to a blower.

[0032] In the above scheme, the package 102 has an air inlet channel 105, whose axis is tangent to the mixing tube 101. When the air enters from the air inlet channel 105, the tangent design enables the incoming air to enter the spiral flow channel 103 around the mixing tube 101 in a relatively fast and smooth manner. Compared with the vertical axis or other non-tangential methods, the tangent air inlet channel 105 can guide the air to enter the spiral flow channel 103 at a specific angle, so as to better conform to the flow direction of the air in the spiral flow channel 103, and help to form a more stable and orderly airflow. The connection between the air inlet channel 105 and the spiral flow channel 103 ensures that the air entering from the air inlet channel 105 can accurately enter the spiral flow channel 103, and then participate in the mixing process of the negative ion flow and the air flow. This connection method ensures the continuity of the air flow, making the entire airflow system an organic whole. If the connection is not smooth or there is a leak, it will affect the flow characteristics of the air flow in the spiral flow channel 103, and then affect the mixing effect of the negative ion flow and the air. The air inlet channel 105 is externally connected to a blower, which is the power source for the air flow in the entire device. The blower provides the necessary power for the air flow to flow in the device by blowing air into the air inlet channel 105. Since a stable and sufficient amount of air flow is required to mix with the negative ion flow during the negative ion self-suspending coating process, the blower can adjust the flow rate and pressure of the blown air according to demand, thereby ensuring that the air flow entering the spiral flow channel 103 can meet the requirements.

[0033] For example, a higher blowing speed can make the air enter the spiral flow channel 103 at a faster speed, forming a stronger airflow in the spiral flow channel 103, which may change the mixing ratio and mixing effect of the negative ion flow and the air flow. Therefore, by accurately controlling the working parameters of the blower, the mixing process of the negative ion flow and the air flow can be finely adjusted to achieve the best coating processing effect.

[0034] Furthermore, the mixing tube 101 has a tapered portion 1011, a mixing portion 1012 and a diffusion portion 1013 in sequence from the feed port 1061 to the discharge port 109, and also includes: an end cover 8, which is covered at the feed port 1061, and has a mounting hole 801 in the middle of the end cover 8, and a first air port 108 on one side of the end cover 8, and the mounting hole 801 and the first air port 108 are both connected to the air flow channel 110; a feed nozzle 106, which is arranged through the mounting hole 801, and the feed nozzle 106 is connected to the negative ion generator, and the nozzle of the feed nozzle 106 is located at the connection between the tapered portion 1011 and the mixing portion 1012, and after the feed nozzle 106 transports the negative ion flow to the air flow channel 110, a negative pressure environment is formed at the tapered portion 1011.

[0035] In the above scheme, the diameter of the converging portion 1011 is gradually reduced. According to the principle of fluid mechanics, when the fluid flows through the area where the diameter is gradually reduced, the flow rate will increase and the pressure will decrease. In this device, the converging portion 1011 can form a negative pressure environment after the feed nozzle 106 conveys the negative ion flow to the air flow channel 110. This negative pressure environment helps to attract the surrounding air flow and preliminarily promotes the mixing of the negative ion flow and the air flow. At the same time, the negative pressure environment also helps to stabilize the flow state of the negative ion flow in the early stage of mixing and prevent the diffusion and disorderly flow of the negative ion flow. Due to the negative pressure environment formed by the converging portion 1011 and the special fluid flow state, the negative ion flow and the air flow can be more fully mixed in the mixing portion 1012. The diffusion portion 1013 is located after the mixing portion 1012, and its function is opposite to the converging portion 1011. The diameter of the diffusion portion 1013 is gradually increased, which helps to reduce the flow rate of the mixed airflow and make the mixed airflow more stable. In the negative ion self-suspension coating process, a stable mixed airflow is very important for subsequent coating processes. The diffuser 1013 can adjust the airflow after being fully mixed by the mixing section 1012 so that it enters the next process at a suitable flow rate and state.

[0036] The end cover 8 covers the feed port 1061, and the mounting hole 801 in the middle is provided for the feed nozzle 106 to penetrate and be installed to connect with the negative ion generator. The first air port 108 on one side is connected with the air flow channel 110, and the two together affect the flow rate and distribution of the air flow. The nozzle of the feed nozzle 106 is located at the connection between the tapered portion 1011 and the mixing portion 1012. With the help of the negative pressure environment of the tapered portion 1011, the negative ion flow can be efficiently sucked in and mixed with the air flow.

[0037] Furthermore, the spiral flow channel 103 is disposed on the mixing portion 1012 , and the spiral flow channel 103 forms a turbulent flow with the negative ion flow after being ventilated into the air flow channel 110 .

[0038] In the above scheme, the spiral flow channel 103 is arranged on the mixing part 1012, and the mixing part 1012 is the key area for the negative ion flow and the air flow to be fully mixed. In the mixing part 1012, the negative ion flow and the air flow have begun to interact with each other, and the spiral flow channel 103 intervenes here, which can further adjust the flow state of the air flow, thereby optimizing the mixing effect of the negative ion flow and the air flow. The spiral flow channel 103 is ventilated into the air flow channel 110. Due to the spiral shape of the spiral flow channel 103, the air flow will produce a rotating effect when entering the air flow channel 110. This rotating air flow meets the negative ion flow originally in the air flow channel 110, changing the air flow environment around the negative ion flow. When the rotating air flow generated by the ventilation of the spiral flow channel 103 interacts with the negative ion flow, turbulence will be formed. Turbulence is a complex fluid flow state, in which parameters such as the velocity and pressure of the fluid show irregular changes in space and time. Turbulence can make the mixing between the negative ion flow and the air flow more sufficient and uniform. Compared with laminar flow (a regular, stable fluid flow state), the fluid particles in turbulent flow will undergo intense mixing and exchange, allowing the negative ion flow and air flow to be fully mixed in a smaller space, thereby improving the mixing efficiency.

[0039] In addition, the presence of turbulence may also help break up the possible agglomeration of negative ions and disperse the negative ions more evenly in the air flow, which is very beneficial for the subsequent formation of a uniform and stable coating on the material surface.

[0040] Furthermore, the spiral flow channel 103 has an air outlet 104, which is connected to the air flow channel 110. The rotating body 2 includes: an impeller 201, which is rotatably arranged in the diffusion section 1013, and the air outlet 104 is used to blow air to the impeller 201; a rotating shaft 202, which is rotatably arranged in the mixing section 1012, and one end of the rotating shaft 202 is arranged on the impeller 201; a rotating block 203, which is conical or truncated cone-shaped, and the other end of the rotating shaft 202 is rotatably arranged on the rotating block 203, and the rotating block 203 is rotatably arranged in the dispersion nozzle 5, and a spray channel 4 is formed between the outer wall of the rotating block 203 and the inner wall of the dispersion nozzle 5.

[0041] In the above scheme, the spiral flow channel 103 has an air outlet 104, and the air outlet 104 is connected to the air flow channel 110. It is ensured that the air flow in the spiral flow channel 103 can enter the next component or area. The impeller 201 is rotatably arranged in the diffuser 1013. When the air blown out from the air outlet 104 of the spiral flow channel 103 acts on the impeller 201, it will provide a rotational power to the impeller 201. The impact force of the air on the impeller 201 will cause the impeller 201 to rotate around its axis. And by adjusting the parameters such as the air flow rate and flow velocity of the air outlet 104, the rotation speed of the impeller 201 can be accurately controlled, thereby realizing the adjustment of the working state of the entire device.

[0042] The impeller 201 is a component that rotates when receiving the air blown by the air outlet 104 of the spiral flow channel 103, and its rotation is transmitted to the rotating block 203 through the rotating shaft 202. One end of the rotating shaft 202 is set on the impeller 201, and the other end is rotatably set on the rotating block 203, so that the rotation of the impeller 201 can effectively drive the rotating block 203 to rotate. The rotating shaft 202 plays the role of transmitting power and connecting two different components (impeller 201 and rotating block 203) during the entire rotation process. The rotating shaft 202 needs to have sufficient strength and stability to ensure that there will be no deformation or breakage during high-speed rotation. The rotating block 203 is conical or truncated, which helps to form a spray channel 4 between the rotating block 203 and the dispersion nozzle 5. The rotating block 203 is rotatably set in the dispersion nozzle 5, and the spray channel 4 is formed between the outer wall of the rotating block 203 and the inner wall of the dispersion nozzle 5.

[0043] The conical or truncated cone-shaped rotating block 203 allows the cross-sectional area of ​​the spray channel 4 to gradually change from one end to the other end of the rotating block 203. When the mixed airflow passes through the spray channel 4, the change in the cross-sectional area helps to further optimize the dispersion effect of the mixed airflow, making the airflow ejected from the spray channel 4 more uniform and stable, thereby better meeting the requirements of the negative ion self-suspended coating processing.

[0044] Furthermore, it also includes: an adjusting ring 6 rotatably disposed on the end cover 8 , the adjusting ring 6 has a shielding portion 601 , and the shielding portion 601 is used to control the opening of the first air outlet 108 .

[0045] In the above scheme, the adjusting ring 6 has a shielding portion 601, and the main function of the shielding portion 601 is to control the opening of the first air outlet 108. The opening of the first air outlet 108 directly affects the air flow rate entering the interior of the device. When the shielding portion 601 partially or completely covers the first air outlet 108, the effective ventilation area of ​​the first air outlet 108 is reduced, thereby reducing the amount of air entering. On the contrary, when the shielding portion 601 is rotated to expose more of the first air outlet 108, the opening of the first air outlet 108 is increased, and more air can enter the interior of the device.

[0046] In the process of negative ion self-suspending film processing, it is very important to accurately control the air flow entering the device. Different working stages or different processing requirements may require different amounts of air to participate in the mixing process of negative ion flow and air flow. By rotating the adjustment ring 6 and adjusting the opening of the first air outlet 108 using the shielding portion 601, fine adjustment of the air flow can be achieved.

[0047] Furthermore, it also includes: a receiving body 3 having a first connection port 301 and a second connection port 302 , the first connection port 301 being screwed to an end of the mixing pipe 101 away from the first air port 108 , and the second connection port 302 being screwed to the dispersion nozzle 5 .

[0048] In the above scheme, the receiving body 3 has a first connection port 301 and a second connection port 302. The first connection port 301 is screwed to the end of the mixing tube 101 away from the first air outlet 108, which can provide a relatively stable connection and ensure the sealing between the mixing tube 101 and the receiving body 3. Compared with other connection methods, screw connection is convenient for installation and disassembly, which is more convenient during equipment maintenance, overhaul or component replacement. The second connection port 302 is screwed to the dispersion nozzle 5. Similarly, this screw connection method ensures a stable connection between the receiving body 3 and the dispersion nozzle 5, and can effectively prevent loosening or leakage between the two during operation. A well-sealed connection is crucial to maintaining the airflow state inside the device, because any leakage may affect the mixing and dispersion of the negative ion flow and the air flow.

[0049] The receiving body 3 plays a connecting role in the structure of the whole device. It connects the mixing tube 101 and the dispersion nozzle 5 together, so that the mixed airflow flowing out of the mixing tube 101 can smoothly enter the dispersion nozzle 5. In addition, the receiving body 3 can be replaced. For example, the length of the receiving body 3 can be increased to meet the requirements of long-distance encapsulation work in a narrow space.

[0050] A negative ion dispersion method comprises the following steps: S1, transporting negative ion flow into the air flow channel 110; S2, conveying air flow into the spiral flow channel 103 through the air inlet channel 105; S3, the air flow in the spiral flow channel 103 is sprayed into the mixing part 1012 in a tangential direction through the air intake to form turbulence with the negative ion flow; S4, the air outlet 104 of the spiral flow channel 103 ejects airflow to drive the impeller 201 to rotate; S5, the impeller 201 drives the rotating block 203 to rotate; S6, the negative ion flow and the air flow are mixed and then sprayed out through the spray channel 4.

[0051] In the above scheme, First, the negative ion generator is started to generate a negative ion flow and transport the negative ion flow into the air flow channel 110. This negative ion flow is the material of the entire dispersion process. The flow state of the negative ion flow in the air flow channel 110 will be affected by the subsequent air flow, and the two will interact to achieve the purpose of mixing. At the same time, the external blower starts to work and transports air flow into the spiral flow channel 103 through the air inlet channel 105. The air inlet channel 105 allows the air flow to enter the spiral flow channel 103 in an orderly manner, which helps to reduce energy loss and allow air to enter the spiral flow channel 103 in a specific tangential direction. When the air flow flows in the spiral flow channel 103, it will flow according to the shape and characteristics of the spiral flow channel 103, preparing for subsequent mixing with the negative ion flow. After the air flow enters the spiral flow channel 103, it is sprayed into the mixing part 1012 in a tangential direction through the air intake to meet the negative ion flow. Since the air flow enters the mixing section 1012 in a tangential direction and has a certain flow rate and pressure, when interacting with the negative ion flow, the original flow state of the negative ion flow will be disrupted, thereby forming turbulence. In the turbulent state, the mixing between the negative ion flow and the air flow becomes more intense and sufficient. The fluid micro-groups quickly exchange positions and energy in the turbulence, so that the negative ions can be better dispersed in the air flow. As the air flow in the spiral flow channel 103 flows, the air flow ejected from its air outlet 104 will blow the impeller 201 to rotate. Since the air outlet 104 is connected to the air flow channel 110, the ejected air flow has enough energy to drive the impeller 201. The impeller 201 is rotatably arranged in the diffuser 1013, and when blown by the air flow, the impeller 201 begins to rotate around its axis. The rotation speed of the impeller 201 depends on factors such as the air flow speed and flow rate of the air outlet 104 and the structural parameters of the impeller 201 itself. The rotation of the impeller 201 is transmitted to the rotating block 203 through the rotating shaft 202, so that the rotating block 203 starts to rotate. After the negative ion flow and the air flow form turbulence and fully mix in the mixing section 1012, the mixed airflow continues to flow to reach the injection channel 4. At this time, due to the rotation of the rotating block 203 and the influence of the injection channel 4, the mixed airflow is finally adjusted in the injection channel 4 between the outer wall circumference of the rotating block 203 and the inner wall of the dispersion nozzle 5, and then ejected outward. In the process of ejection, the mixed airflow leaves the device in a relatively stable and uniform state. This stable and uniform mixed airflow has a key role for the subsequent application of the negative ion self-suspended coating processing, such as forming a uniform coating on the material surface.

[0052] Furthermore, the specific steps of S6 are: After the impeller 201 delivers the mixed airflow into the injection channel 4, the rotating block 203 drives the mixed airflow to be ejected in a spiral shape.

[0053] In the above scheme, the rotating block 203 is conical or truncated cone shaped and is rotatably arranged in the dispersion nozzle 5. After the impeller 201 delivers the mixed airflow to the spray channel 4, the rotation of the rotating block 203 begins to guide the mixed airflow. Due to the shape and rotational motion of the rotating block 203, it will form a spiral flow field in the spray channel 4. Specifically, the spray channel 4 is formed between the outer wall circumference of the rotating block 203 and the inner wall of the dispersion nozzle 5. When the rotating block 203 rotates, the mixed airflow is affected by various forces such as friction and centrifugal force on the surface of the rotating block 203 in this relatively narrow channel. The conical or truncated cone structure of the rotating block 203 causes the mixed airflow to generate circular motion in the part close to the surface of the rotating block 203 as the rotating block 203 rotates, and due to the limitation of the spray channel 4, this circular motion is converted into a spiral motion along the channel direction.

[0054] The spiral airflow can better maintain its stability and directionality after being ejected. In the application of negative ion self-suspended coating technology, this stable and directional spiral mixed airflow can cover the surface of the material more evenly, which helps to form a uniform and stable coating. For example, when manufacturing air purifier filter elements in the field of air purification, this spirally ejected mixed airflow can more effectively distribute negative ions evenly on the filter element material, thereby improving the filter element's ability to remove harmful substances in the air such as PM2.5, formaldehyde, benzene, etc.; when manufacturing water purifier filter elements in the field of water treatment, it can also make negative ions more evenly distributed on the filter element, enhancing the removal effect of harmful substances such as heavy metals, bacteria, viruses, etc. in the water; when manufacturing medical devices or health products in the field of medical care, it is conducive to forming a uniform negative ion coating on the product surface, thereby better playing a role in improving human health (such as improving immunity, promoting blood circulation, relieving fatigue, etc.).
