[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] Example 1

[0027] like Figures 1 to 6 As shown, an air disinfection and purification device described in an embodiment of the present invention includes an air pump 1 and a fixed shell 2; a circular tube 3 is fixed between the two ends of the fixed shell 2, a transition tube 4 is fixed between one end of the circular tube 3 and the outlet end of the air pump 1, and a plasma generator 5 is provided on the transition tube 4; an air diffuser 6 is provided at the other end of the circular tube 3; an annular permanent magnet 7 is fixed to the inner circular wall of the fixed shell 2, an annular electrode 8 is provided between the annular permanent magnet 7 and the circular tube 3, and the annular electrode 8 is fixed to the inner wall of the shell and the fixed shell 2; a spiral air guide plate 9 is fixed to the inner wall of the circular tube 3, a group of guide fins 10 are provided in the circular tube 3, and the distribution position of the guide fins 10 corresponds to the spiral line position of the spiral air guide plate 9; a spiral electrode 8 is fixed to the spiral air guide plate 9 pole; a rotating part is provided in the circular tube 3, and the guide fin 10 is adjusted to a rotation angle by rotating; during operation, the air pump 1 transports air to the transition duct 4, where the plasma generator 5 preliminarily ionizes the air; the air then enters the circular tube 3, and the spiral air guide plate 9 guides the air to spiral forward. During this process, the spiral electrode and the annular electrode 8 generate an electric field to further ionize the air; the magnetic field generated by the annular permanent magnet 7 is perpendicular to the electric field, forming a composite field, in which the charged particles perform a spiral motion, increasing the probability of ionization; the guide fin 10 can adjust the angle through the rotating part to control the air flow rate and direction, enhance heat exchange, and promote air ionization and plasma mixing; finally, the purified air is discharged through the air diffuser 6 to expand the range of action.

[0028] The rotating member includes a rotating rod 11, a group of rotating rods 11 are rotatably connected between the two ends of the inner wall of the circular tube 3, and the rotating rods 11 pass through the spiral air guide plate 9 and are fixedly connected to the guide fins 10, a group of the rotating rods 11 are fixedly connected to a rotating gear 12, and the end of the circular tube 3 is rotatably connected to a rotating gear ring 13; the side wall of the fixed shell 2 is fixedly connected to a micro motor 14 through a placement groove, and the output end of the micro motor 14 is fixedly connected to a transmission gear 15, and the rotating gear ring 13, the rotating gear 12 and the transmission gear 15 are all meshed; during operation, when it is necessary to adjust the guide plate 9, the rotating gear 12 is fixedly connected to the guide fin 10, and the rotating gear 12 is fixedly connected to the guide fin 10; When the angle of the guide fin 10 is adjusted, the micro motor 14 starts, and the transmission gear 15 at its output end rotates, driving the rotating gear ring 13 to rotate; the rotation of the rotating gear ring 13 causes the rotating gear 12 meshing with it to rotate, and the rotating gear 12 drives the rotating rod 11 to rotate, thereby adjusting the angle of the guide fin 10 fixed to the rotating rod 11; in this way, the angle of the guide fin 10 can be accurately controlled according to the air temperature, flow rate and other conditions in the spiral air guide channel, the air flow rate and flow direction can be adjusted, the heat exchange between the air and the outside world can be enhanced, and the stable and efficient operation of the equipment can be guaranteed.

[0029] The inner wall of the circular tube 3 is provided with a guide groove 16, and the guide groove 16 is a continuous corrugation; the corrugation of the guide groove 16 is a sine curve, and the crests and troughs of adjacent corrugations are staggered with each other; during operation, the air flows in the circular tube 3, and the corrugated guide groove 16 guides the direction and adjusts the speed of the airflow multiple times; due to the special shape of the guide groove 16, the airflow continuously changes its flow rate and pressure during the flow process, forming local eddies and turbulence at the crests and troughs; these eddies and turbulence extend the residence time of the air in the channel, and the staggered corrugations can also disperse the impact force of the airflow and reduce the wear on the inner wall of the circular tube 3.

[0030] The guide groove 16 extends in a spiral shape, and the depth and width of the guide groove 16 gradually change from the air inlet to the air outlet, which is shallower and narrower at the air inlet and deeper and wider at the air outlet; during operation, air enters the circular tube 3 from the air inlet and spirals forward under the guidance of the guide groove 16; the shallower and narrower guide groove 16 at the air inlet makes the air flow faster, and as the air flows to the air outlet, the guide groove 16 gradually becomes deeper and wider, the air flow rate slows down, and the pressure changes, which further aggravates the degree of disorder of the airflow and forms more eddies and turbulence; this not only allows the air to stay longer in the channel, but also promotes full contact between the air and the fins and electrodes, improves the air ionization and mixing effects, and enhances the air disinfection and purification efficiency.

[0031] Furthermore, a retractable self-cleaning electrode protective net is provided on the outside of the annular electrode 8; the protective net is woven from high-strength, well-conductive and corrosion-resistant metal wire, and the surface of the metal wire is coated with a nano-scale super-hydrophobic self-cleaning coating; the protective net is connected to the fixed shell 2 through a guide rail, and can be radially retracted along the annular electrode 8 under the drive of a motor; a pulse power supply is arranged between the protective net and the annular electrode 8, which can generate instantaneous high-voltage pulses; the metal wire of the protective net is made of shape memory alloy material and woven into a diamond pore structure; a miniature shape memory alloy spring is installed on the diagonal of each diamond pore; a temperature sensing strip is provided on the edge of the protective net, and the sensing strip is connected to the miniature spring; at the same time, a row of tiny electrostatic adsorption teeth are evenly distributed on the edge of the protective net; the electrostatic adsorption teeth are made of a material with good tip discharge performance, and the tooth tip is needle-shaped, which is connected to the electrostatic generating device inside the protective net. A tiny air vent is opened on the side of each electrostatic adsorption tooth, and the diameter of the air vent is smaller than the size of common dust particles.

[0032] Example 2

[0033] like Figures 1 to 6 As shown, a group of cones 17 are fixedly connected to the side walls of both sides of a group of guide fins 10, and a group of serrated grooves 18 are opened on the side walls around the guide fins 10; a group of disturbing bodies are fixedly connected to the spiral electrode, and the disturbing bodies are slender and conical; during operation, when the guide fins 10 rotate, the cones 17 and serrated grooves 18 on the side walls will disrupt the air flow, generate more tiny vortices, increase the contact area between the air and the fin surface, enhance heat exchange, and make the air movement trajectory more complicated, increase the contact opportunity with the electrode, and promote air ionization and plasma mixing; the slender conical disturbing body on the spiral electrode will also disrupt the air flowing through, causing the air to form more local vortices on the electrode surface, increasing the contact between the air and the electrode, improving the plasma generation efficiency, and accelerating the decomposition of harmful components.

[0034] Furthermore, a group of the sawtooth grooves 18 are fixed with barbs at the tooth tips; a group of the cones 17 are provided with micro-memory alloy wires; the barb structure adopts a flexible conductive polymer material, which can produce a weak piezoelectric effect when deformed by force; the micro-memory alloy wire is connected to the temperature control system in the guide fin 10. When the temperature of the fin changes, the shape memory alloy wire will deform accordingly, causing the micro-nano cone 17 to expand or contract or bend.

[0035] The spiral electrode has a hollow structure, and the internal filling material of the spiral electrode has high thermal conductivity and electrical conductivity; the spiral air guide plate 9 is fixedly connected with micro-magnetic conductive material, and an insulating isolation pad is fixedly connected between the micro-magnetic conductive material and the spiral electrode; when working, the hollow structure of the spiral electrode and the high thermal conductivity and electrical conductivity material filled inside can effectively improve the heat dissipation performance, ensure the stability of the electrode under high-load operation, and at the same time enhance the electrical conductivity and improve the ionization efficiency; the micro-magnetic conductive material on the spiral air guide plate 9 guides the magnetic field, so that the air is better guided and constrained by the magnetic field during the spiral advancement process, and the motion trajectory of the charged particles changes under the action of the magnetic field, prolonging the residence time in the electric field and increasing the ionization probability; the insulating isolation pad prevents electrical connection between the micro-magnetic conductive material and the spiral electrode, ensuring the normal operation of each component.

[0036] Example 3

[0037] like Figures 1 to 6 As shown, a temperature sensor is provided in the guide fin 10; the surface of the guide fin 10 is coated with a high thermal conductivity insulating material; when working, the temperature sensor monitors the air temperature in the spiral air guide channel in real time; when the air temperature is too high, the temperature sensor transmits a signal to the micro motor 14, and the micro motor 14 drives the guide fin 10 to rotate, adjusts the fin angle, adjusts the air flow rate and direction, and enhances the heat exchange between the air and the outside world; the high thermal conductivity insulating material coated on the surface of the guide fin 10 can, on the one hand, quickly transfer heat to the temperature sensor inside the fin, so that it can sense temperature changes in time; on the other hand, the insulation performance can prevent the fin from being electrified and affecting the normal operation of the equipment, ensuring that the equipment operates efficiently in a suitable temperature environment.

[0038] The surfaces of a group of the cones 17 are all provided with aerogel through grooves; when working, the aerogel has the characteristics of high porosity and low density, and its surface has been specially treated to have super hydrophobicity and self-cleaning ability; when air flows through the cone 17 on the side wall of the guide fin 10, the aerogel absorbs tiny particles in the air, reducing the risk of particles contaminating the spiral electrode and the annular electrode 8. At the same time, the super hydrophobicity and self-cleaning properties of the aerogel prevent pollutants from accumulating in the grooves, ensuring the long-term stable operation of the structure, thereby ensuring the continuous and efficient operation of the air disinfection and purification device.

[0039] Working principle: the air pump 1 delivers air to the transition duct 4, where the plasma generator 5 performs preliminary ionization on the air; the air then enters the circular tube 3, and the spiral air guide plate 9 guides the air to spiral forward. In this process, the spiral electrode and the annular electrode 8 generate an electric field to further ionize the air; the magnetic field generated by the annular permanent magnet 7 is perpendicular to the electric field, forming a composite field, and the charged particles perform spiral motion in the composite field, increasing the probability of ionization; the guide fins 10 can adjust the angle through the rotating parts to regulate the air flow rate and direction, enhance heat exchange, and promote air ionization and plasma mixing; finally, the purified air is discharged through the air diffuser 6 to expand the range of action. When the angle of the guide fins 10 needs to be adjusted, the micro-electrode The motor 14 is started, and the transmission gear 15 at its output end rotates, driving the rotating gear ring 13 to rotate; the rotation of the rotating gear ring 13 causes the rotating gear 12 meshing with it to rotate, and the rotating gear 12 drives the rotating rod 11 to rotate, thereby adjusting the angle of the guide fin 10 fixed to the rotating rod 11; in this way, the angle of the guide fin 10 can be accurately controlled according to the air temperature, flow rate and other conditions in the spiral air guide channel, the air flow rate and flow direction can be adjusted, the heat exchange between the air and the outside world can be enhanced, and the stable and efficient operation of the equipment can be guaranteed. The air flows in the circular tube 3, and the corrugated guide groove 16 guides the direction and adjusts the speed of the airflow multiple times; due to the special shape of the guide groove 16, the airflow constantly changes its flow rate and pressure during the flow process. The vortexes and turbulences extend the residence time of the air in the channel. At the same time, the staggered corrugations can disperse the impact of the airflow and reduce the wear on the inner wall of the circular tube 3. The air enters the circular tube 3 from the air inlet and spirals forward under the guidance of the guide groove 16. The shallower and narrower guide groove 16 at the air inlet makes the air flow faster. As the air flows to the air outlet, the guide groove 16 gradually becomes deeper and wider, the air flow rate slows down, and the pressure changes, which further aggravates the turbulence of the airflow and forms more vortexes and turbulence. This not only allows the air to stay longer in the channel, but also promotes full contact between the air and the fins and electrodes, thereby improving the air ionization and mixing effect, and enhancing the air disinfection and purification efficiency. During the rotation of the fin 10, the cone 17 and the serrated groove 18 on its side wall will disrupt the air flow, generate more tiny eddies, increase the contact area between the air and the fin surface, enhance heat exchange, and at the same time make the air movement trajectory more complex, increase the contact opportunity with the electrode, and promote air ionization and plasma mixing; the slender conical disruptor body on the spiral electrode will also disrupt the air flowing through, causing the air to form more local eddies on the electrode surface, increasing the contact between the air and the electrode, improving the efficiency of plasma generation, and accelerating the decomposition of harmful components. The hollow structure of the spiral electrode and the high thermal and conductive materials filled inside can effectively improve the heat dissipation performance, ensure the stability of the electrode under high-load operation, and at the same time enhance the conductivity and improve the ionization efficiency;The micro-magnetic material on the spiral air guide plate 9 guides the magnetic field, so that the air is better guided and constrained by the magnetic field during the spiral advance. The motion trajectory of the charged particles changes under the action of the magnetic field, prolonging the residence time in the electric field and increasing the probability of ionization; the insulating isolation pad prevents electrical connection between the micro-magnetic material and the spiral electrode, ensuring the normal operation of each component, and the temperature sensor monitors the air temperature in the spiral air guide channel in real time; when the air temperature is too high, the temperature sensor transmits the signal to the micro-motor 14, and the micro-motor 14 drives the guide fins 10 to rotate, adjusts the fin angle, adjusts the air flow rate and flow direction, and enhances the heat exchange between the air and the outside world; the high thermal conductivity insulating material coated on the surface of the guide fins 10 The material can quickly transfer heat to the temperature sensor inside the fin, allowing it to sense temperature changes in a timely manner. Its insulating properties prevent the fin from becoming electrically charged and affecting the normal operation of the device, ensuring efficient operation of the device under suitable temperature conditions. Aerogel has high porosity and low density, and its surface has been specially treated to be super-hydrophobic and self-cleaning. When air flows through the cone 17 on the side wall of the guide fin 10, the aerogel absorbs tiny particles in the air, reducing the risk of particle contamination of the spiral and annular electrodes 8. At the same time, the super-hydrophobic and self-cleaning properties of the aerogel prevent contaminants from accumulating in the grooves, ensuring long-term stable operation of the structure and, in turn, ensuring the continued efficient operation of the air disinfection and purification device.
