[0002] In the prior art, the air outlet of the air conditioner can adjust the air direction, but the range is very limited. After the air conditioner is turned on, it often causes the area where the cold air of the indoor air conditioner can blow to be too cold, and some places that cannot be blown are too hot. Sometimes the local indoor temperature of the same air conditioner can differ by more than 5 degrees, resulting in energy waste and discomfort for people. To solve the technical problems raised in the above background art, in the prior art, a patent document with the publication number CN219868387U discloses an energy-saving air conditioner air direction control device, including a housing, a front cover is arranged on the housing, and a cross-flow fan is arranged inside the housing.

The bottom end of the housing is provided with a first air deflector, a second air deflector and a third air deflector, and connection blocks are fixed at both ends of the first air deflector, the second air deflector and the third air deflector. The above device can evenly send the cold air to various places in the room, so that the temperature difference between the corners of the room will not be too large. While saving energy, it can also improve people's comfort. However, the above air direction control device has the following technical problems when in use: Existing air conditioner air direction control devices usually adopt a single mechanical transmission method, which can only achieve simple swing adjustment, and cannot accurately control the swing frequency and amplitude according to different usage scenarios. The air outlet function of the existing device is relatively fixed, lacking a diversified function switching mechanism. The adjustment range of the existing air conditioner air outlet is very limited, which easily causes too large local differences in indoor temperature. Based on this, the present invention provides an energy-saving air conditioner air direction control device to solve the technical problems raised in the above background art.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention uses three semi-toothed gears with a tooth number ratio of 8:9:10 to be linked with the transmission shaft through a bushing and cooperate with a driven gear with 10 teeth. At the same time, the relative position of the semi-toothed gear and the driven gear can be adjusted through the lead screw linear transmission module, thereby changing the rotation frequency and stroke of the axial screw. During the working process, the second motor drives the transmission shaft to rotate, and the bushing drives the semi-toothed gear to rotate. When semi-toothed gears with different numbers of teeth mesh with the driven gear, the axial screw produces reciprocating rotation at different speeds due to the tooth number difference, 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 semi-toothed gear with a large number of teeth to increase the rotation amplitude of the axial screw. When the silent mode is required, it is switched to the gear with a small number of teeth to reduce the swing frequency. This precise control method realizes the adaptive adjustment of the function belt under different wind speed and wind direction requirements. Compared with the prior art, through the precise ratio of gear transmission, the energy consumption of ineffective actions is reduced, the wind direction adjustment is more in line with the actual needs, and the energy-saving effect is remarkable.

[0015] 2. The present invention effectively solves the problem that the air outlet function of the existing air conditioner air direction control device is relatively fixed and lacks a diversified function switching mechanism by setting ventilation sections with different ventilation functions. There are six ventilation sections equidistantly arranged on the function belt, and the ventilation functions of each ventilation section are different. The switching of each ventilation section is completed by the first motor driving the roller, which is triggered by the microcontroller according to environmental data or manual mode. The honeycomb area is suitable for scenarios that require quietness, and the noise is reduced through the honeycomb holes and sound-absorbing cotton. The vertical hole area and the horizontal hole area are suitable for scenarios that require large-area ventilation, and the air flow is guided to spread vertically or horizontally through the vertical strip holes and the horizontal strip holes respectively. The filter membrane area is suitable for situations where there is oil fume or pet odor in the room, and pollutants are adsorbed by activated carbon. The sterilization area is suitable for scenarios that require sterilization, and bacteria and harmful gases are decomposed through the flexible UV sterilization and odor removal composite membrane. The fragrance area is suitable for scenarios that require atmosphere improvement, and fragrance is released through the fragrance slow-release soft sheet material. 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 selections, providing a better user experience.

[0016] 3. By adopting designs such as a telescopic tube lined with a shaping spring and a magnetically attractable first louver, the present invention effectively solves the problems that the adjustment range of the existing air outlet of the air conditioner is limited and it is easy to cause too large local differences in indoor temperature. The cross-section of the telescopic tube is square, and it is lined with a shaping spring made of nickel-titanium memory alloy. A permanent magnet that magnetically attracts the housing is fixedly arranged on the first louver, and a hidden handle is provided on the end face of the first louver for changing its layout position and layout angle. When the position and angle change, the shaping spring self-limits the position and angle of the first louver, thereby changing the air outlet position and air outlet angle of the first louver. Through directional air outlet and close-range air outlet, it can effectively reduce temperature waste, and then improve the energy-saving effect of this air direction control device. When it is necessary to adjust the air outlet position or air outlet area of the air conditioner, the first louver at the specified position can be opened and arranged at the set position and set angle, while the first louvers in the non-specified air distribution area are in the closed state. At the same time, through the setting of the adjusting push rod, the unfolding length of the functional belt relative to the housing can be adjusted, and then the maximum air outlet area of this air outlet mechanism of the air conditioner can be adjusted.

[0017] 4. By setting components such as a spiral filter screen, a magnetic vibration coating, and a magnetic field generator, the present invention realizes the self-cleaning function of the filter screen, effectively solving the problems that the traditional air conditioner filter screen is easily blocked, needs to be frequently cleaned, and affects the ventilation efficiency. When returning air, the driving module drives the filter shaft to reciprocate along the axis of the return air duct and rotate synchronously through the bevel gear transmission of the axial screw and the longitudinal screw. The magnetic vibration coating on the spiral filter screen generates three-axis micro-movements under the action of the magnetic field generator, and the magnetic ring deformation adjusts the aperture of the filter holes, realizing the self-cleaning and high-efficiency filtration of the filter screen. When the axial flow fan drives the return air through the spiral filter screen, dust particles are intercepted. When it is necessary to adjust the aperture of the filter holes or cause the magnetic vibration coating to vibrate, the magnetic field generator is started. The magnetic ring expands or contracts the filter holes under the action of the magnetic field, and at the same time the magnetic vibration coating vibrates, causing the dust to fall off and be discharged through the ash discharge valve. This self-cleaning function avoids manual disassembly and cleaning, keeps the filter screen transparent, reduces the energy consumption increased by the fan due to increased resistance, not only reduces the maintenance cost, but also enables the air conditioner system to always maintain a low-energy consumption operation state through continuous and efficient filtration and ventilation.

A torsion spring 11 is provided at the rotational connection of the axial screw 8 and the bracket 7. A sleeve 12 is linked on the transmission shaft 10. Three semi-toothed gears 13 with the same radius are installed on the sleeve 12. The tooth numbers of the three semi-toothed gears 13 are in the ratio of 8:9:10. A driven gear 14 adapted to be connected with the semi-toothed gears 13 is installed on the axial screw 8. The relative positions of the three semi-toothed gears 13 and the driven gear 14 are adjustable, and a reciprocating frame 15 is drivingly installed on the axial screw 8; The tooth numbers of the three semi-toothed gears 13 are 80, 90, and 100 respectively, the tooth number of the driven gear 14 is 10, and the radius of the semi-toothed gear 13 is 8 times the radius of the driven gear 14; It further includes a lead screw linear transmission module 40 installed on the bracket 7. A speed regulation frame 41 is drivingly connected to the lead screw linear transmission module 40. The sleeve 12 is rotatably installed on the speed regulation frame 41. A second square groove with both ends open and slidably connected to the transmission shaft 10 is fixedly opened inside the sleeve 12. The cross-sections of the second square groove and the transmission shaft 10 are both regular polygons; The three semi-toothed gears 13 with a tooth number ratio of 8:9:10 are linked with the transmission shaft 10 through the sleeve 12. Cooperating with the driven gear 14 with a tooth number of 10, the relative positions of the semi-toothed gears 13 and the driven gear 14 can be adjusted through the lead screw linear transmission module 40, thereby changing the rotation frequency and stroke of the axial screw 8; In the working process, the second motor 9 drives the transmission shaft 10 to rotate, and the sleeve 12 drives the semi-toothed gears 13 to rotate. When the semi-toothed gears 13 with different tooth numbers mesh with the driven gear 14, the axial screw 8 makes reciprocating rotations at different speeds due to the tooth number difference, 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 single adjustment mode and inability to accurately control the swing frequency of the traditional air direction control device, and can realize the adaptive adjustment of the functional zone 19 under different wind speed and wind direction requirements; When the screw linear transmission module 40 works, by setting the angle of the transmission shaft 10, the notch position of the semi-toothed gear 13 should correspond to the driven gear 14, thereby avoiding gear collision and gear movement interference during the operation of the screw linear transmission module 40; The functional belt 19 is made of polyimide; When wide-angle air supply is required, switch to the engagement of the semi-toothed gear 13 with large number of teeth to increase the rotation amplitude of the axial screw 8; When the silent mode is required, switch to the small-toothed gear to reduce the swing frequency; Compared with the prior art, through the precise ratio of gear transmission, it reduces the energy consumption of ineffective actions, makes the air direction adjustment more in line with the actual needs, and has a significant energy-saving effect; In actual production, the inner wall of the housing 1 is adhered with sound-absorbing cotton; Both the semi-toothed gear 13 and the driven gear 14 are coated with a rubber coating, and the thickness of the rubber coating is 1.5 mm. The rubber coating is used to reduce the collision and noise rate between gears; A set of adjusting push rods 16 are installed between the reciprocating frame 15 and the adjusting frame 2. Both the reciprocating frame 15 and the adjusting frame 2 are rotatably installed with rollers 18 driven by a first motor 17. A functional belt 19 is wound between the two rollers 18. A plurality of ventilation sections 20 are equidistantly arranged on the functional belt 19, and the ventilation functions of each ventilation section 20 are different; Both the first motor 17 and the second motor 9 are internally provided with encoders connected to the microcontroller 31; The number of ventilation sections 20 is six. The six ventilation sections 20 are respectively a honeycomb area, a vertical hole area, a horizontal hole area, a filter membrane area, a sterilization area and an aromatic area; The honeycomb area is provided with honeycomb holes in an array and a sound-absorbing cotton is adhered to its back surface. The aperture of the honeycomb holes is 0.5 mm; Vertical strip holes are evenly distributed on the vertical hole area, and horizontal strip holes are evenly distributed on the horizontal hole area. The axes of the vertical strip holes are perpendicular to the axes of the horizontal strip holes. The cross-sections of the vertical strip holes and the horizontal strip holes are both trapezoidal; The filter membrane area is an activated carbon soft filter membrane. The activated carbon soft filter membrane is made by compounding activated carbon particles with a flexible polymer substrate. The particle size of the activated carbon particles is 50 mesh, and the flexible polymer substrate is polyvinyl alcohol; The sterilization area is a flexible UV sterilization and deodorization composite film; 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; The aromatic area is a fragrance slow-release soft sheet material; The fragrance slow-release soft sheet material is composed of a porous polyurethane sponge and a non-woven fabric; Openings are provided in the filter membrane area, the sterilization area, and the fragrance area for installing the activated carbon soft filter membrane, the flexible UV sterilization and odor removal composite membrane, and the fragrance slow-release soft sheet material; Each ventilation section 20 has the same length. The length of the functional zone 19 is 10 times the width of the first louver 6. Sealing zones 30 are provided at positions corresponding to the intervals between two ventilation sections 20 on the functional zone 19, and the length of the sealing zone 30 is 0.5 times the length of the ventilation section 20; The switching of each ventilation section 20 is completed by the first motor 17 driving the roller 18, which is triggered by the microcontroller 31 according to environmental data or manual mode; Among them, the honeycomb area is suitable for scenarios that require quietness. A noise sensor is configured on the air conditioner. When the microcontroller 31 detects that the environmental noise is greater than 45 dB or the user selects the "quiet mode", it switches, and the noise is reduced through the honeycomb holes; The vertical hole area and the horizontal hole area are suitable for scenarios that require large-area ventilation. When the microcontroller 31 determines that wide-angle air supply is needed, it switches, and the air flow is guided to diffuse vertically or horizontally through the vertical strip holes and the horizontal strip holes respectively; The filter membrane area is suitable for indoor environments with oil fumes and pet odors. An air quality sensor is configured on the air conditioner. When the air quality sensor detects that the pollutant concentration exceeds the standard or the user selects the "purification mode", it switches, and the pollutants are adsorbed by the activated carbon; The sterilization area is suitable for scenarios that require sterilization. It switches in a high-humidity environment or when the user selects the "sterilization mode", and the flexible UV sterilization and odor removal composite membrane decomposes bacteria and harmful gases; The fragrance area is suitable for scenarios that require an improved atmosphere. It switches when the user selects the "aromatherapy mode" or is triggered by a timer, and the fragrance is released through the fragrance slow-release soft sheet material; When switching, it follows the energy-saving logic of activating on demand, dynamic matching, and life optimization; When it is necessary to adjust the air outlet position or the air outlet area of this air conditioner, the first louver 6 at the specified position can be opened and arranged at the set position and the set angle; The first louvers 6 in the non-specified air distribution area are in the closed state; By adjusting the setting of the push rod 16, the deployment length of the functional zone 19 relative to the housing 1 can be adjusted, and then the maximum air outlet area of the air outlet mechanism of this air conditioner can be adjusted; When the air outlet area of this device is adjusted, the air outlet direction of the ventilation pipe 22 can be adjusted through the setting of the second louver 23. By restricting the air outlet direction of the ventilation pipe 22, it corresponds to the air outlet area and the air outlet center position of this device; A corrugated cover 21 is provided on the air collector box 3. The reciprocating frame 15 and the adjustment frame 2 are both connected to the corrugated cover 21. A ventilation pipe 22 communicating with the air collector box 3 is installed on the support 7, and a second louver 23 is provided at the connection of the ventilation pipe 22 and the air collector box 3; 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 electronic control end of the magnetic field generator 29 are both connected to the microcontroller 31 for data connection. A refrigeration module 24 is connected to the ventilation pipe 22. The second louver 23 is used to change the air outlet angle. When the adjusting push rod 16 works, the corrugated cover 21 deforms in a follow-up manner. When the honeycomb area and the vertical hole area face the air inlet, when the semi-tooth gear 13 with 80 teeth meshes with the driven gear 14, the low-frequency and large-amplitude vibration generated can make the functional belt 19 move slowly, which is suitable for scenarios where a constant wind direction is required. When the semi-tooth gear 13 with 90 teeth meshes, the medium-frequency and medium-amplitude vibration is realized, and the air outlet direction changes uniformly within the set angle range. For example, in the wide-angle air supply mode in the living room of a family, the air flow coverage range can be expanded. When the semi-tooth gear 13 with 100 teeth meshes, the high-frequency and small-amplitude vibration is generated, which promotes the functional belt 19 to move quickly and slightly, making the air flow direction at the air outlet 4 present a "micro-sweeping" state. It is suitable for scenarios where rapid cooling and air pollutant dispersion are required. By changing the wind direction frequently, the air circulation is accelerated. In addition, when the vibration mode is switched, the transmission accuracy of the adjusting push rod 16 ensures that the displacement of the functional belt 19 is synchronized with the wind direction adjustment, avoiding wind direction control deviation caused by vibration. Cooperating with the microcontroller 31 to control the magnetic field generator 29 and the louver in a linkage manner, the accurate matching of the wind direction angle, the air supply range and the ventilation section 20 switching is realized, improving the dynamic adaptability of wind direction control while saving energy.

A magnetic ring is embedded in the hole wall of the filter hole 28, and the magnetic ring deforms under the action of the magnetic field to adjust the aperture of the filter hole 28. The magneto-vibration coating is affected by the magnetic field of the magnetic field generator 29 and generates three-axis micro-vibration.

[0023] The magneto-vibration coating is a composite coating of nickel-zinc ferrite micro-powder and silicone rubber matrix. The particle size of the nickel-zinc ferrite micro-powder is 1μm, the thickness of the magneto-vibration coating is 50μm, the magnetic ring is made of manganese-zinc ferrite, and the magnetic ring is circular; 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 states of the magnetic field generator 29, the shutter and the refrigeration module 24 according to the data; The temperature and humidity probe 32 continuously monitors the environmental temperature and humidity. When the temperature is higher than the set value, the microcontroller 31 controls the refrigeration module 24 to enhance refrigeration, and at the same time adjusts the second shutter 23 to increase the air output; When the humidity is too high, the telescopic pipe 5 is controlled to adjust the air outlet angle to accelerate air circulation to reduce the humidity; The magnetic field generator 29 adjusts the magnetic field intensity according to the instruction of the microcontroller 31, so that the magnetic ring deforms to adjust the aperture of the filter hole 28, optimizing the return air efficiency. This design solves the problem that traditional air conditioners cannot adaptively adjust according to environmental changes and avoids energy waste caused by excessive refrigeration or dehumidification; When the humidity is low, the aperture of the filter hole 28 is reduced to reduce the return air resistance and lower the energy consumption of the fan; When the temperature is suitable, it switches to the natural ventilation mode and turns off the refrigeration module 24. Compared with the prior art, through real-time environmental perception and intelligent control, it realizes dynamic optimization of energy consumption and improves the energy-saving effect; When returning air, the driving module drives the filter axis 26 to reciprocate 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 magneto-vibration coating on the spiral filter screen 27 generates three-axis micro-vibration under the action of the magnetic field generator 29, and the magnetic ring deforms to adjust the aperture of the filter hole 28, realizing self-cleaning and efficient filtration of the filter screen; When the axial flow fan drives the return air through the spiral filter screen 27, dust particles are intercepted; When it is necessary to adjust the aperture of the filter hole 28 or cause the magneto-vibration coating to vibrate, the magnetic field generator 29 is started. The magnetic ring expands or contracts the filter hole 28 under the action of the magnetic field. At the same time, the magneto-vibration coating vibrates, causing the dust to fall off and be discharged through the ash discharge valve 35; The transmission design of the drive module enables the filter shaft 26 to complete full-range cleaning during reciprocating movement, avoiding manual disassembly and cleaning. This design solves the problems of traditional air conditioner filters being prone to blockage, requiring frequent cleaning, and affecting ventilation efficiency. By means of the self-cleaning function, the filter screen is kept transparent, reducing the energy consumption increased by the fan due to increased resistance. Compared with the prior art, it not only reduces the maintenance cost, but also enables the air conditioner system to always maintain a low-energy consumption operation state through continuous and efficient filtration and ventilation; The magnetic field generator 29 generates a controllable magnetic field. The magnetic ring is made of manganese-zinc ferrite, which belongs to soft magnetic material and has a relatively high magnetic permeability. When the magnetic field generator 29 outputs a magnetic field, the magnetic ring will undergo magnetostrictive effect in the magnetic field, that is, the internal magnetic domains are rearranged under the action of the magnetic field force, resulting in the deformation of the magnetic ring. When the magnetic field intensity increases, the magnetic ring expands outward, making the aperture of the filter hole 28 larger; When the magnetic field intensity decreases, the magnetic ring contracts and the aperture of the filter hole 28 becomes smaller, thus realizing the adjustment of the aperture of the filter hole 28; The axial strain of the magnetic ring is 0.1 - 0.3 mm; The magnetic ring is embedded in the wall of the filter hole 28 by interference fit; This device can dynamically adjust the size of the filter hole 28 according to different filtration requirements, reducing the aperture when high-efficiency filtration is needed and increasing the aperture when reducing air resistance. The magneto-vibration coating is composed of nickel-zinc ferrite micropowder and silicone rubber matrix. The nickel-zinc ferrite micropowder has ferromagnetism. When the magnetic field generated by the magnetic field generator 29 acts on the magneto-vibration coating, the nickel-zinc ferrite micropowder particles will be affected by the alternating magnetic field force. Since the magnetic field is in three-axis directions, the micropowder particles will be affected by the magnetic field force in three directions, thus generating vibrations in three-axis directions, driving the silicone rubber matrix to vibrate together, forming three-axis micro-vibrations. This three-axis vibration can make dust and other pollutants on the spiral filter screen 27 fall off more easily, enhancing the self-cleaning effect of the spiral lifting filter screen.

[0024] A return air inlet is provided at the lower part of the housing 1. A third louver 33 is installed inside the return air inlet. The back of the return air inlet is communicated with a return air cover 34. The return air cover 34 is communicated with the return air duct 25. An axial flow fan and a one-way return air valve are installed in sequence along the return air direction inside the return air duct 25. A dust discharge valve 35 is communicated with the return air duct 25 at a position corresponding to directly below the spiral filter screen 27. A guide roller 42 is rotatably installed on both the reciprocating frame 15 and the adjusting frame 2.

[0025] The return air inlet at the lower part of the housing 1 controls the air intake volume through the third louver 33. The return air cover 34 is communicated with 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 the dust falling off the spiral filter screen 27. When the air conditioner is running, the third louver 33 adjusts the opening degree according to the instruction of the microcontroller 31. The axial flow fan sucks the indoor air into the return air duct 25, and after being filtered by the spiral filter screen 27, it enters the refrigeration module 24; The filtered dust accumulates at the bottom of the spiral filter screen 27 and can be discharged by regularly opening the ash discharge valve 35. This design solves the problems of easy dust accumulation in the traditional air return system of air conditioners, which affects air quality and equipment performance. All three louvers are electric louvers. When the functional belt 19 is worn out, it should be replaced regularly. The working principle and usage process of the present invention: During operation, the third louver 33 at the lower air return opening of the housing 1 adjusts the air intake volume under the control of the microcontroller 31. Indoor air enters the air return pipe 25 through the air return hood 34. The axial flow fan drives the air to pass through the spiral filter screen 27 for filtration, and the dust is intercepted. The filtered air enters the refrigeration module 24 to be cooled or heated, 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 refrigeration module 24, the magnetic field generator 29 and each louver accordingly. The second motor 9 drives the transmission shaft 10 to rotate. The shaft sleeve 12 drives the three half-tooth gears 13 with a tooth ratio of 8:9:10 to rotate. The relative position of the half-tooth gear 13 and the driven gear 14 is adjusted through the lead screw linear transmission module 40, changing the rotation frequency and stroke of the axial lead screw 8. The adjustment frame 2 is driven by the reciprocating frame 15 and the adjustment push rod 16, thereby adjusting the unfolded length and air outlet area of the functional belt 19 relative to the housing 1. The first motor 17 drives the roller 18 to switch the functional belt 19 to different ventilation sections 20. The honeycomb area with honeycomb holes and sound-absorbing cotton is used during silent operation, and the filter membrane area of the activated carbon soft filter membrane is used during purification. At the same time, the drive module drives the filter shaft 26 to reciprocate and rotate synchronously in the air return pipe 25 through the bevel gear transmission of the axial lead screw 8 and the longitudinal lead screw 39. The magnetic field generator 29 generates a magnetic field to deform the magnetic ring, adjusting the aperture of the filter holes 28. The magnetic vibration coating generates three-axis micro-movements to achieve self-cleaning of the filter screen. The dust is discharged through the ash discharge valve 35. The telescopic pipe 5 is lined with a nickel-titanium memory alloy shaping spring and is magnetically attracted and fixed by the permanent magnet of the first louver 6, which can change the air outlet position and angle, realizing directional or close-range air outlet, reducing temperature waste and achieving energy-saving effects.
