[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention adopts three half-tooth gears with a gear ratio of 8:9:10 to be linked to the transmission shaft through a shaft sleeve, and cooperates with a driven gear with a tooth number of 10. At the same time, the relative position of the half-tooth gears and the driven gear can be adjusted through the screw linear transmission module, thereby changing the rotation frequency and stroke of the axial screw. During operation, the second motor drives the transmission shaft to rotate, and the shaft sleeve drives the half-tooth gears to rotate. When the half-tooth gears with different tooth numbers are engaged with the driven gear, the axial screw produces reciprocating rotation at different rates due to the difference in tooth number, and then drives the adjustment frame to move through the reciprocating frame and the adjustment push rod. When wide-angle air supply is required, it can be switched to the large-tooth half-tooth gear meshing to increase the rotation amplitude of the axial screw. When silent mode is required, it can be switched to the small-tooth gear to reduce the swing frequency. This precise control method realizes the adaptive adjustment of the functional belt under different wind speed and wind direction requirements. Compared with the existing technology, the precise ratio of gear transmission reduces the energy consumption of ineffective action, makes the wind direction adjustment more in line with actual needs, and has a significant energy-saving effect.

[0017] 2. The present invention effectively solves the problem that the air outlet function of the existing air-conditioning wind direction control device is relatively fixed and lacks a diversified function switching mechanism by setting ventilation sections with different ventilation functions. Six ventilation sections are equidistantly arranged on the functional belt, and the ventilation function of each ventilation section is different. The switching of each ventilation section is completed by the first motor driving the roller, and the microcontroller is triggered according to environmental data or manual mode. The honeycomb area is suitable for scenes that require quietness, and the noise is reduced by honeycomb holes and silencer cotton. The vertical hole area and the horizontal hole area are suitable for scenes that require large-area ventilation, and the airflow is guided to diffuse vertically or horizontally through the vertical holes and horizontal holes respectively. The filter membrane area is suitable for scenes with oil smoke and pet odor in the room, and activated carbon is used to adsorb pollutants. The sterilization area is suitable for scenes that require sterilization, and bacteria and harmful gases are decomposed through a flexible UV sterilization and deodorization composite film. The fragrance sheet area is suitable for scenes that need to improve the atmosphere, and fragrance is released through a fragrance-releasing soft sheet. This energy-saving logic of on-demand activation, dynamic matching and life optimization enables the air conditioner to flexibly switch ventilation sections according to different environmental requirements and user choices, providing a better user experience.

[0018] 3. The present invention effectively solves the problem of limited adjustment range of existing air-conditioning outlets, which easily causes large local differences in indoor temperature, by adopting designs such as a telescopic tube lined with a plastic spring and a magnetically attracted first venetian blind. The cross-section of the telescopic tube is square and lined with a plastic spring made of nickel-titanium memory alloy. A permanent magnet that is magnetically attracted to the housing is fixed on the first venetian blind. The end face of the first venetian blind is provided with a hidden handle for changing its layout position and layout angle. When the position and angle change, the plastic spring self-limits the position and angle of the first venetian blind. , thereby changing the air outlet position and air outlet angle of the first louver. Through directional air outlet and close-type air outlet, temperature waste can be effectively reduced, thereby improving the energy-saving effect of the wind direction control device. When the air outlet position or air outlet area of ​​the air conditioner needs to be adjusted, the first louver at the designated position can be opened and arranged at the set position and set angle, and the first louver in the non-designated air distribution area is in a closed state. At the same time, by adjusting the setting of the push rod, the expanded length of the functional belt relative to the shell can be adjusted, thereby adjusting the maximum air outlet area of ​​the air outlet mechanism of the air conditioner.

[0019] 4. The present invention achieves a self-cleaning filter by incorporating components such as a spiral filter, a magnetic vibration coating, and a magnetic field generator. This effectively addresses the problem of traditional air conditioning filters being easily clogged, requiring frequent cleaning, and affecting ventilation efficiency. During return air flow, the drive module, through the bevel gear transmission of the axial and longitudinal screws, drives the filter shaft to reciprocate and rotate synchronously along the axis of the return air duct. The magnetic vibration coating on the spiral filter generates three-axis micro-motion under the action of the magnetic field generator, and the magnetic ring adjusts the filter pore diameter, achieving self-cleaning and high-efficiency filtration. When the axial flow fan drives the return air through the spiral filter, dust particles are trapped. When the filter pore diameter needs to be adjusted or the magnetic vibration coating needs to be vibrated, the magnetic field generator is activated. The magnetic field causes the magnetic ring to expand or contract the filter pores, and the magnetic vibration coating vibrates, causing dust to fall off and be discharged through the dust discharge valve. This self-cleaning function eliminates manual disassembly and cleaning, maintains the filter's transparency, and reduces the energy consumption of the fan due to increased resistance. This not only reduces maintenance costs but also ensures that the air conditioning system maintains low energy consumption through continuous and efficient filtration and ventilation.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] like Figures 1 to 12As shown, the present invention provides an energy-saving air-conditioning wind direction control device, comprising a housing 1, an adjustment frame 2, an air collecting box 3, and a bracket 7 mounted on the housing 1. A plurality of air outlets 4 are opened on the upper portion of the housing 1, each of which is equipped with a telescopic tube 5, and a first louver 6 is mounted at the front end of each telescopic tube 5;

[0035] A microcontroller 31 is mounted on the end surface of the housing 1;

[0036] There are six air outlets 4, and a permanent magnet that is magnetically attracted to the housing 1 is fixed on the first louver 6;

[0037] A hidden handle is provided on the end surface of the first louver 6, and the hidden handle is used to change the layout position and layout angle of the first louver 6;

[0038] When the position and angle of the first louver 6 change, the plastic spring self-limits the position and angle of the first louver 6, thereby changing the air outlet position and air outlet angle of the first louver 6;

[0039] The cross section of the telescopic tube 5 is square, and the telescopic tube 5 is lined with a plastic spring made of nickel-titanium memory alloy;

[0040] Through directional and close-fitting air outlets, temperature waste is effectively reduced, thereby improving the energy-saving effect of the wind direction control device;

[0041] An axial screw 8 and a transmission shaft 10 driven by a second motor 9 are rotatably mounted on the bracket 7. A torsion spring 11 is provided at the rotational connection between the axial screw 8 and the bracket 7. A shaft sleeve 12 is linked to the transmission shaft 10. Three half-tooth gears 13 with the same radius are mounted on the shaft sleeve 12. The gear ratio of the three half-tooth gears 13 is 8:9:10. A driven gear 14 adapted to be connected to the half-tooth gears 13 is mounted on the axial screw 8. The relative positions of the three half-tooth gears 13 and the driven gear 14 are adjustable. A reciprocating frame 15 is transmission-mounted on the axial screw 8.

[0042] The numbers of teeth of the three half-toothed gears 13 are 80, 90 and 100 respectively, the number of teeth of the driven gear 14 is 10, and the radius of the half-toothed gear 13 is 8 times the radius of the driven gear 14;

[0043] The invention also includes a screw linear transmission module 40 mounted on the bracket 7, the screw linear transmission module 40 is transmission-connected to a speed regulating frame 41, the shaft sleeve 12 is rotatably mounted on the speed regulating frame 41, and the shaft sleeve 12 has a second square groove fixedly formed inside with openings at both ends and slidably connected to the transmission shaft 10, and the cross-sections of the second square groove and the transmission shaft 10 are both regular polygons;

[0044] Three half-tooth gears 13 with a gear ratio of 8:9:10 are linked to the transmission shaft 10 through the shaft sleeve 12 and cooperate with the driven gear 14 with 10 teeth. The relative positions of the half-tooth gears 13 and the driven gear 14 can be adjusted through the screw linear transmission module 40, thereby changing the rotation frequency and stroke of the axial screw 8;

[0045] During the working process, the second motor 9 drives the transmission shaft 10 to rotate, and the shaft sleeve 12 drives the half-tooth gear 13 to rotate. When the half-tooth gears 13 with different numbers of teeth engage with the driven gear 14, the axial screw 8 reciprocates at different rates due to the difference in the number of teeth, and then drives the adjustment frame 2 to move through the reciprocating frame 15 and the adjustment push rod 16. This design solves the problems of the traditional wind direction control device with a single adjustment mode and the inability to accurately control the swing frequency, and can realize the adaptive adjustment of the functional belt 19 under different wind speed and wind direction requirements;

[0046] When the screw linear transmission module 40 is in operation, the angle of the transmission shaft 10 should be set so that the notch position of the half-tooth gear 13 corresponds to the driven gear 14, thereby avoiding gear collision and gear motion interference during operation of the screw linear transmission module 40;

[0047] The functional belt 19 is made of polyimide;

[0048] When wide-angle air supply is required, the large-toothed half-tooth gear 13 is switched to mesh, increasing the rotation amplitude of the axial screw 8;

[0049] When silent mode is required, switch to a gear with a small number of teeth to reduce the oscillation frequency;

[0050] Compared with the existing technology, it reduces the energy consumption of ineffective movement through the precise ratio of gear transmission, makes the wind direction adjustment more in line with actual needs, and has a significant energy-saving effect;

[0051] In actual production, the inner wall of the housing 1 is adhered with sound-absorbing cotton;

[0052] The half-tooth gear 13 and the driven gear 14 are both coated with a rubber coating with a thickness of 1.5 mm. The rubber coating is used to reduce the collision and noise rate between the gears.

[0053] A set of adjusting push rods 16 are installed between the reciprocating frame 15 and the adjusting frame 2. Rollers 18 driven by a first motor 17 are rotatably installed on both the reciprocating frame 15 and the adjusting frame 2. A functional belt 19 is wound between the two rollers 18. Multiple ventilation segments 20 are equidistantly arranged on the functional belt 19. Each ventilation segment 20 has a different ventilation function.

[0054] The first motor 17 and the second motor 9 are both equipped with built-in encoders connected to the microcontroller 31;

[0055] There are six ventilation sections 20, which are respectively a honeycomb area, a vertical hole area, a horizontal hole area, a filter membrane area, a sterilization area and a scented sheet area.

[0056] The honeycomb area is arrayed with honeycomb holes and the back of the honeycomb area is bonded with sound-absorbing cotton. The diameter of the honeycomb holes is 0.5mm.

[0057] The vertical hole area is evenly distributed with vertical holes, and the horizontal hole area is evenly distributed with horizontal holes. The axes of the vertical holes are perpendicular to the axes of the horizontal holes, and the cross sections of the vertical holes and the horizontal holes are both trapezoidal.

[0058] The filter membrane area is an activated carbon soft filter membrane, which is made of a composite of activated carbon particles and a flexible polymer substrate. The particle size of the activated carbon particles is 50 mesh, and the flexible polymer substrate is polyvinyl alcohol.

[0059] The sterilization area is a flexible UV sterilization and deodorization composite film;

[0060] The flexible UV sterilization and deodorization composite film includes a base layer and a functional layer. The base layer is a polyester film, and the functional layer is a composite coating of titanium dioxide photocatalyst and UV-C fluorescent coating coated on the base layer.

[0061] The scented sheet area is a soft sheet material with slow-release fragrance;

[0062] The fragrance slow-release soft sheet is made of a composite of porous polyurethane sponge and non-woven fabric;

[0063] There are openings on the filter membrane area, sterilization area and fragrance sheet area, which are used for the installation of activated carbon soft filter membrane, flexible UV sterilization and deodorization composite membrane and fragrance slow-release soft sheet;

[0064] Each ventilation section 20 has the same length. The length of the functional belt 19 is 10 times the width of the first louver 6. A sealing area 30 is provided on the functional belt 19 and correspondingly between each two ventilation sections 20. The length of the sealing area 30 is 0.5 times the length of the ventilation section 20.

[0065] The switching of each ventilation section 20 is completed by the first motor 17 driving the roller 18, and the microcontroller 31 is triggered according to environmental data or manual mode;

[0066] Among them, the honeycomb area is suitable for scenes that require quietness. The air conditioner is equipped with a noise sensor. When the microcontroller 31 detects that the ambient noise is greater than 45dB or the user selects the "silent mode", it switches to reduce the noise through the honeycomb holes;

[0067] The vertical hole area and the horizontal hole area are suitable for scenes requiring large-area ventilation. When the microcontroller 31 determines that wide-angle air supply is required, it switches to guide the airflow to diffuse vertically or horizontally through the vertical holes and the horizontal holes respectively;

[0068] The filter membrane area is suitable for indoor environments with oil smoke and pet odors. The air conditioner is equipped with an air quality sensor. When the air quality sensor detects that the pollutant concentration exceeds the standard or the user selects "purification mode", it switches to activated carbon to absorb pollutants;

[0069] The sterilization area is suitable for scenarios where sterilization is required. It switches to "sterilization mode" in high humidity environments or when the user selects it. It decomposes bacteria and harmful gases through a flexible UV sterilization and deodorization composite film.

[0070] The scent sheet area is suitable for scenes that need to improve the atmosphere. It switches when the user selects "aromatherapy mode" or is triggered by a timer, and releases fragrance through the scent-releasing soft sheet;

[0071] When switching, it follows the energy-saving logic of on-demand activation, dynamic matching and life optimization;

[0072] When the air outlet position or air outlet area of ​​the air conditioner needs to be adjusted, the first louver 6 at the designated position can be opened and arranged at the set position and set angle;

[0073] The first blinds 6 in the non-designated air distribution area are in a closed state;

[0074] By adjusting the setting of the push rod 16, the extended length of the functional belt 19 relative to the housing 1 can be adjusted, thereby adjusting the maximum air outlet area of ​​the air outlet mechanism of the air conditioner;

[0075] When the air outlet area of ​​the device is adjusted, the air outlet direction of the ventilation pipe 22 can be adjusted by setting the second louver 23. By limiting the air outlet direction of the ventilation pipe 22, the air outlet area and the air outlet center position of the device are matched.

[0076] The air collecting box 3 is provided with a corrugated cover 21, the reciprocating frame 15 and the adjustment frame 2 are connected to the corrugated cover 21, the bracket 7 is provided with a ventilation pipe 22 connected to the air collecting box 3, and a second louver 23 is provided at the connection between the ventilation pipe 22 and the air collecting box 3;

[0077] A temperature and humidity probe 32 is installed on the air collecting box 3. The data end of the temperature and humidity probe 32 and the electric control end of the magnetic field generator 29 are both data-connected to the microcontroller 31. The ventilation pipe 22 is connected to the refrigeration module 24.

[0078] The second louver 23 is used to change the air outlet angle;

[0079] When the adjusting push rod 16 works, the bellows 21 deforms dynamically;

[0080] When the honeycomb area and the vertical hole area face the air inlet, when the half-tooth gear 13 with 80 teeth meshes with the driven gear 14, the low-frequency and large-amplitude vibration generated can cause the functional belt 19 to move slowly, which is suitable for scenarios requiring a constant wind direction;

[0081] The medium-frequency medium-amplitude vibration of the half-tooth gear 13 with 90 teeth when meshing achieves uniform changes in the air outlet direction within a set angle range, such as the wide-angle air supply mode in a family living room, which can expand the airflow coverage range;

[0082] The high-frequency, small-amplitude vibration generated by the meshing of the half-tooth gear 13 with 100 teeth prompts the functional belt 19 to move quickly and slightly, causing the airflow direction of the air outlet 4 to present a "micro-sweeping" state. This is suitable for scenarios that require rapid cooling and the dispersal of air pollutants, and accelerates air circulation by changing the wind direction at high frequency.

[0083] In addition, when the vibration mode is switched, the transmission accuracy of the adjustment push rod 16 ensures that the displacement of the functional belt 19 is synchronized with the wind direction adjustment, avoiding the wind direction control deviation caused by vibration, and cooperates with the microcontroller 31 to control the linkage of the magnetic field generator 29 and the blinds to achieve precise matching of the wind direction angle, air supply range and ventilation section 20 switching, thereby improving the dynamic adaptability of wind direction control while saving energy.

[0084] The bottom end of the ventilation pipe 22 is connected to the return air pipe 25;

[0085] The connection between the ventilation pipe 22 and the return air pipe 25 is provided with a corrugated expansion part;

[0086] The bracket 7 is equipped with a driving module, and the driving module is equipped with a filter shaft 26 that can reciprocate along the axis of the return air duct 25 and rotate synchronously.

[0087] The drive module includes a vibration frame 36, a gear shaft 37 rotatably connected to the bracket 7, a guide rotary sleeve 38 rotatably connected to the air collecting box 3, a longitudinal screw 39 rotatably mounted on the bracket 7, and a first bevel gear 39 and an axial screw 8 are mounted on the longitudinal screw 39, and the two first bevel gears are orthogonally meshed;

[0088] The longitudinal screw 39 is connected to the vibration frame 36 in transmission connection, and a synchronous toothed belt is connected between the transmission shaft 10 and the gear shaft 37. A second bevel gear is installed on the gear shaft 37 and the guide rotary sleeve 38. The two second bevel gears are orthogonally meshed. A square linkage section is provided on the upper part of the filter shaft 26. The square linkage section is rotatably mounted on the vibration frame 36. A first square groove is fixedly opened inside the guide rotary sleeve 38 and is slidably connected to the square linkage section. The cross-sections of the first square groove and the square linkage section are both regular polygons.

[0089] A spiral filter screen 27 is installed on the filter shaft 26 at a position corresponding to the inner side of the return air duct 25. The spiral filter screen 27 is provided with a magnetic vibration coating and vertically arranged filter holes 28 are evenly distributed on the spiral filter screen 27. A magnetic field generator 29 is installed on the return air duct 25. A magnetic ring is embedded in the hole wall of the filter hole 28. The magnetic ring is deformed under the action of the magnetic field to adjust the aperture of the filter hole 28. The magnetic vibration coating is affected by the magnetic field of the magnetic field generator 29 and produces three-axis micro-motion.

[0090] The magnetic resonance coating is a composite coating of nickel-zinc ferrite powder and silicone rubber matrix. The particle size of the nickel-zinc ferrite powder is 1 μm, the thickness of the magnetic resonance coating is 50 μm, and the magnetic ring is made of manganese-zinc ferrite and is in a circular shape.

[0091] The temperature and humidity probe 32 on the air collecting box 3 collects environmental data in real time and transmits it to the microcontroller 31. The microcontroller 31 adjusts the working state of the magnetic field generator 29, the blinds and the refrigeration module 24 according to the data;

[0092] The temperature and humidity probe 32 continuously monitors the ambient temperature and humidity. When the temperature is higher than the set value, the microcontroller 31 controls the refrigeration module 24 to increase the cooling and adjusts the second louver 23 to increase the air volume.

[0093] When the humidity is too high, the telescopic tube 5 is controlled to adjust the air outlet angle to accelerate air circulation to reduce the humidity;

[0094] The magnetic field generator 29 adjusts the magnetic field strength according to the instructions of the microcontroller 31, so that the magnetic ring can adjust the aperture of the filter 28 to optimize the return air efficiency. This design solves the problem that traditional air conditioners cannot adapt to environmental changes and avoids energy waste caused by excessive cooling or dehumidification.

[0095] When the humidity is low, reduce the filter hole 28 aperture to reduce the return air resistance and reduce the fan energy consumption;

[0096] When the temperature is suitable, the system switches to natural ventilation mode and turns off the refrigeration module 24. Compared with the existing technology, this system achieves dynamic optimization of energy consumption and improves energy saving effects through real-time environmental perception and intelligent regulation.

[0097] During return air flow, the drive module drives the filter shaft 26 to move back and forth along the axis of the return air duct 25 and rotate synchronously through the bevel gear transmission of the axial screw 8 and the longitudinal screw 39. The magnetic vibration coating on the spiral filter 27 produces three-axis micro-motion under the action of the magnetic field generator 29, and the magnetic ring changes to adjust the aperture of the filter hole 28, achieving self-cleaning and high-efficiency filtration of the filter.

[0098] When the axial flow fan drives the return air through the spiral filter 27, the dust particles are trapped;

[0099] When it is necessary to adjust the pore size of the filter 28 or to cause the magnetic vibration coating to vibrate, start the magnetic field generator 29, the magnetic ring is affected by the magnetic field to expand or contract the filter pore 28, while the magnetic vibration coating vibrates, causing dust to fall off and be discharged through the ash discharge valve 35;

[0100] The drive module's transmission design enables the filter shaft 26 to complete full-range cleaning during reciprocating motion, eliminating the need for manual disassembly and cleaning. This design addresses the issue of traditional air conditioning filters being easily clogged, requiring frequent cleaning, and impacting ventilation efficiency. The self-cleaning function maintains filter transparency, reducing energy consumption due to increased fan resistance. Compared to existing technologies, this design not only reduces maintenance costs but also enables the air conditioning system to maintain low energy consumption through continuous and efficient filtration and ventilation.

[0101] The magnetic field generator 29 generates a controllable magnetic field. The magnetic ring is made of manganese-zinc ferrite, which is a soft magnetic material with high magnetic permeability. When the magnetic field generator 29 outputs a magnetic field, the magnetic ring will undergo a magnetostrictive effect in the magnetic field. That is, the internal magnetic domains are rearranged by the magnetic field force, causing the magnetic ring to deform. When the magnetic field intensity increases, the magnetic ring expands outward, causing the aperture of the filter 28 to increase.

[0102] When the magnetic field intensity decreases, the magnetic ring contracts and the aperture of the filter hole 28 becomes smaller, thereby achieving the adjustment of the aperture of the filter hole 28;

[0103] The axial strain of the magnetic ring is 0.1-0.3mm;

[0104] The magnetic ring is embedded in the filter hole wall with interference fit;

[0105] This device can dynamically adjust the size of the filter hole 28 according to different filtering requirements, reducing the aperture when high-efficiency filtration is required, and increasing the aperture when wind resistance needs to be reduced. The magnetic vibration coating is composed of a composite of nickel-zinc ferrite micropowder and a silicone rubber matrix. The nickel-zinc ferrite micropowder is ferromagnetic. When the magnetic field generated by the magnetic field generator 29 acts on the magnetic vibration coating, the nickel-zinc ferrite micropowder particles will be affected by the alternating magnetic field force. Since the magnetic field is triaxial, the micropowder particles will be affected by the magnetic field force in three directions, thereby generating triaxial vibrations, driving the silicone rubber matrix to vibrate together, forming triaxial micro-motion. This triaxial vibration can make it easier for pollutants such as dust on the spiral filter 27 to fall off, and the spiral enhances the self-cleaning effect of the filter.

[0106] A return air outlet is provided at the lower part of the shell 1, and a third louver 33 is installed inside the return air outlet. The back of the return air outlet is connected to a return air cover 34, and the return air cover 34 is connected to the return air duct 25. An axial flow fan and a one-way return air valve are installed in sequence inside the return air duct 25 along the return air direction. An ash discharge valve 35 is connected to the return air duct 25 and the position directly below the spiral filter 27 is connected. A guide roller 42 is rotatably installed on both the reciprocating frame 15 and the adjustment frame 2.

[0107] The return air vent at the bottom of the housing 1 controls the air intake through a third louver 33. The return air cover 34 is connected to the return air duct 25. The internal axial flow fan and one-way return air valve ensure smooth return air. The dust discharge valve 35 can regularly clean dust that falls off the spiral filter 27. When the air conditioner is running, the third louver 33 adjusts its opening according to the instructions of the microcontroller 31. The axial flow fan draws indoor air into the return air duct 25, and the air is filtered by the spiral filter 27 before entering the cooling module 24.

[0108] The filtered dust is deposited at the bottom of the spiral filter 27 and can be discharged by regularly opening the dust discharge valve 35. This design solves the problem of dust accumulation in traditional air conditioning return systems, which affects air quality and equipment performance.

[0109] All three blinds are electric;

[0110] Functional belt 19 should be replaced regularly when it is worn out;

[0111] The working principle and use process of the present invention:

[0112] During operation, the third louver 33 at the return air outlet at the lower part of the housing 1 adjusts the air intake volume under the control of the microcontroller 31. The indoor air enters the return air duct 25 through the return air cover 34. The axial flow fan drives the air through the spiral filter 27 to filter and trap dust. The filtered air enters the refrigeration module 24 for cooling or heating, and then enters the air collecting box 3 through the ventilation pipe 22. The temperature and humidity probe 32 on the air collecting box 3 monitors the environmental data in real time and transmits it to the microcontroller 31. The microcontroller 31 controls the operation of the refrigeration module 24, the magnetic field generator 29 and the louvers accordingly.

[0113] The second motor 9 drives the transmission shaft 10 to rotate, and the shaft sleeve 12 drives the three half-tooth gears 13 with a gear ratio of 8:9:10 to rotate. The relative position of the half-tooth gear 13 and the driven gear 14 is adjusted by the screw linear transmission module 40, and the rotation frequency and stroke of the axial screw 8 are changed. The reciprocating frame 15 and the adjustment push rod 16 drive the adjustment frame 2 to move, thereby adjusting the expansion length and air outlet area of ​​the functional belt 19 relative to the shell 1. The first motor 17 drives the roller 18 to switch the functional belt 19 to different ventilation sections 20. When silent, use the honeycomb area with honeycomb holes and silencer cotton. When purifying, The filter membrane area of ​​the activated carbon soft filter membrane is used. At the same time, the driving module drives the filter shaft 26 to move back and forth and rotate synchronously in the return air duct 25 through the bevel gear transmission of the axial screw 8 and the longitudinal screw 39. The magnetic field generator 29 generates a magnetic field to change the magnetic ring, adjust the aperture of the filter hole 28, and the magnetic vibration coating produces three-axis micro-motion to achieve self-cleaning of the filter. The dust is discharged through the ash discharge valve 35. The telescopic tube 5 is lined with a nickel-titanium memory alloy plastic spring, which is fixed by the permanent magnet of the first louver 6. The air outlet position and angle can be changed to achieve directional or close air outlet, reduce temperature waste, and achieve energy saving effects.
