[0036] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] like Figure 1-13 As shown, a circulating air supply sterilization device includes a body 1 and air ducts 12 arranged in a circumferential array along a vertical direction. Cleaning filters 72 are movably installed within the body 1 along the ventilation paths of the multiple air ducts 12. A replacement unit is movably installed within the body 1, and the replacement unit includes:

[0038] The ring 2 moves vertically and has a high position and a low position, and when the ring 2 is in the high position, it pushes multiple cleaning filters 72 to be exposed.

[0039] Locking rods 43 are symmetrically slidably disposed on the ring 2, and when the ring 2 is in the low position, the two locking rods 43 lock the ring 2 onto the body 1;

[0040] The fastening rods 9 are multiple and slide on the ring 2 respectively. When the ring 2 is in the low position, the fastening rods 9 pull the cleaning filter 72 to adhere to the ring 2.

[0041] Specifically, it also includes a blower hood 17, and the bottom end of the guide rod 18 fixedly installed inside the blower hood 17 is fixedly installed on the inner wall of the cavity 11 opened inside the body 1. Multiple windows 23 matching the cleaning filter 72 are opened on the outer wall of the ring 2, and the cleaning filter 72 is movably set on one side of the window 23. A blower 32 and a main motor 33 for driving the blower 32 to blow air into the multiple windows 23 are fixedly installed inside the blower hood 17.

[0042] Furthermore, a base plate 22 is fixedly installed at the bottom of the ring 2, and the base plate 22 is slidably set on the outer wall of the guide rod 18 so that the ring 2 moves in the vertical direction. At the same time, two locking rods 43 are symmetrically slidably set on the base plate 22. Locking grooves 16 are symmetrically opened on the inner wall of the cavity 11. When the ring 2 is in the low position, the first ends of the two locking rods 43 are respectively inserted into the locking grooves 16 so that the ring 2 is locked and fixed on the body 1. At the same time, multiple fastening rods 9 are used to pull the cleaning filter 72 to adhere to the ring 2. Then, multiple fastening rods 9 and the ring 2 are used to clamp and fix multiple cleaning filters 72. Then, the blower 32 blows air into the ring 2. The blown air flows along multiple windows 23. The cleaning filter 72 on one side of the window 23 filters the air drawn in by the blower 32. Then, the filtered blown air is discharged along multiple air passages 12.

[0043] Furthermore, when it is necessary to quickly replace multiple cleaning filters 72 on the ring sleeve 2, the two locking rods 43 are driven to slide out of the two locking grooves 16, so that the ring sleeve 2 can be unlocked and slidable. Then, by pushing the ring sleeve 2 upward and placing it in a high position, the multiple cleaning filters 72 are exposed. Then, by driving the multiple fastening rods 9 to slide again, the tension and fixation on the cleaning filters 72 are released, which makes it easy to replace the cleaning filters 72.

[0044] The ring 2 can be moved vertically by means of a motor in conjunction with gears and racks; by means of an electric push rod; or by means of driving the ring 2 to move vertically as known to those skilled in the art.

[0045] The locking rod 43 can slide in any way, such as by using a motor in conjunction with gears and a connecting rod; or by using an electric push rod in conjunction with a connecting rod; or by any method known to those skilled in the art to drive the locking rod 43 to slide.

[0046] The sliding of multiple fastening rods 9 can be achieved by using an electric push rod in conjunction with a connecting rod; a motor in conjunction with gears and racks; or any method known to those skilled in the art for driving the fastening rods 9 to slide.

[0047] In the above technical solution, the cleaning filter 72 is located on the ventilation path of the air duct 12 to filter the blower gas. The locking rod 43 is slid to unlock the ring 2 and then drive the ring 2 to move vertically and to a high position to expose the cleaning filter 72. At this time, multiple fastening rods 9 are slid to release the pull and fixation on multiple cleaning filters 72, so that multiple cleaning filters 72 can be easily removed from the ring 2 for replacement.

[0048] As a further embodiment of the present invention, a rotating block 25 is rotatably provided inside the ring 2, and a lever 19 is symmetrically provided on the moving path of the ring 2. The first end of the lever 19 is slidably provided in the first curved guide groove 26 opened on the outer wall of the rotating block 25, and a plurality of push plates 28 provided on the rotating block 25 are respectively located on the moving path of the fastening rod 9.

[0049] Specifically, two levers 19 are symmetrically fixed inside the blower shroud 17, and the rotating block 25 is rotatably mounted on the base plate 22 and sleeved on the outer wall of the guide rod 18, as shown below. Figure 2 and Figure 3 As shown, when the ring 2 is locked to the body 1 by the two locking rods 43, the ring 2 is in a low position, and the first ends of the two levers 19 are respectively located at the top of the first curved guide groove 26.

[0050] like Figure 3 and Figure 6 As shown, a baffle 24 is fixedly installed on one side of window 23. Multiple fastening rods 9 matching window 23 slide on the ring 2. At the same time, the protrusion 93 fixedly installed at the first end of the fastening rod 9 is located on one side of the baffle 24. The curved block 91 fixedly installed at the second end of the fastening rod 9 is located on the moving path of the push plate 28. A tension spring 92 is fixedly installed on the fastening rod 9. The tension spring 92 pushes the fastening rod 9 so that the protrusion 93 fits against the baffle 24. Multiple fixing rods 27 matching window 23 are fixedly installed on the outer wall of the rotating block 25. Multiple push plates 28 are fixedly installed on the fixing rods 27.

[0051] Furthermore, when the cleaning filter 72 needs to be replaced, the locking rod 43 is slid to unlock the ring 2, which then moves the ring 2 vertically. At this time, the first ends of the two levers 19 move from the top to the bottom of the first curved guide groove 26, and the rotating block 25 rotates on the base plate 22. When the rotating block 25 rotates, it drives the push plate 28 to rotate. At the same time, the end of the push plate 28 slides away from the curved surface on the curved block 91. Then, the tension spring 92 pushes the fastening rod 9 so that the protrusion 93 fits against the retainer 24, thereby releasing the compression and fixation of the fastening rod 9 and the ring 2 on the cleaning filter 72. At the same time, when the ring 2 is in the high position, the first ends of the two levers 19 are located at the bottom of the first curved guide groove 26, and the cleaning filter 72 is exposed for easy replacement.

[0052] Furthermore, after the cleaning filter 72 is replaced, the ring 2 is driven to move down from the high position to the low position again. At this time, the first ends of the two levers 19 move from the bottom end of the first curved guide groove 26 to the top end of the first curved guide groove 26. The rotating block 25 rotates again so that the ends of the multiple push plates 28 gradually approach the multiple curved blocks 91. Then, the multiple push plates 28 slide along the curved surface of the curved block 91 to squeeze the curved block 91 and make the multiple fastening rods 9 slide. At this time, the multiple protrusions 93 gradually fit onto the multiple cleaning filters 72 and cooperate with the outer wall of the ring 2 to clamp and fix the cleaning filters 72 respectively.

[0053] Furthermore, by using the locking rod 43 to slide and unlock the ring 2, and by moving the ring 2 upward to expose the cleaning filter 72, the time required to replace the cleaning filter 72 can be greatly reduced compared to manually removing the screws. In addition, the cleaning filter 72 is clamped by the fastening rod 9 and the ring 2 to ensure the stability of the cleaning filter 72 during use.

[0054] As another embodiment of the present invention, the outer wall of the ring 2 is provided with a plurality of arc-shaped rods 7 that rotate synchronously with the rotating block 25, and the outer wall of the ring 2 is fixedly installed with a baffle 24 on one side of the cleaning filter 72. A plurality of elastic strips 71 are fixedly installed between the arc-shaped rods 7 and the baffle 24, and the arc-shaped rods 7 rotate to make the plurality of elastic strips 71 adhere to the cleaning filter 72.

[0055] Specifically, such as Figure 11 As shown, multiple arc-shaped rods 7 are fixedly installed at the ends of multiple fixed rods 27, and the multiple fixed rods 27 are slidably disposed on the ring 2. At the same time, the thickness of the arc-shaped rods 7 is less than the thickness of the cleaning filter 72, and the arc-shaped rods 7 slide along the outer wall of the ring 2.

[0056] Furthermore, when the ring 2 is in the high position, the cleaning filter 72 is exposed for easy replacement. By placing the new cleaning filter 72 between the baffle 24 and the ring 2, and positioning the cleaning filter 72 on top of the arc-shaped rod 7, the side of the cleaning filter 72 extends beyond the top side of the arc-shaped rod 7. Then, by driving the ring 2 down from the high position to the low position again, the first ends of the two levers 19 move along the bottom to the top of the first curved guide groove 26, respectively. The rotating block 25 rotates again so that the ends of the multiple push plates 28 gradually approach the multiple curved blocks 91. Simultaneously, the arc-shaped rod 7 and the rotating block 25 rotate synchronously, and the arc-shaped rod 7 moves along the outer wall of the ring 2. At this time, the elastic strip 71 is stretched taut due to the rotation of the arc-shaped rod 7, as... Figure 7 and Figure 11 As shown, at this time, the elastic strip 71 deforms and straightens, tightly adhering to the cleaning filter 72. The cleaning filter 72 is pushed by the elastic strip 71 to move closer to the outer wall of the ring 2. Then, multiple push plates 28 slide along the curved surface of the curved block 91 to squeeze the curved block 91 and make multiple fastening rods 9 slide. At this time, multiple protrusions 93 gradually adhere to multiple cleaning filters 72 and cooperate with the outer wall of the ring 2 to clamp and fix the cleaning filter 72 respectively. Furthermore, the elastic strip 71 pushes the cleaning filter 72 to further tighten the cleaning filter 72 to adhere to the ring 2, thereby improving the stability of the cleaning filter 72.

[0057] Furthermore, the elastic strip 71 is made of high-temperature resistant rubber. The cleaning filter 72 is quickly installed by inserting it between the baffle 24 and the ring 2. The first step involves clamping and securing the cleaning filter 72 using the fastening rod 9 and the ring 2. Then, the elastic strip 71 pushes the cleaning filter 72 tightly against the ring 2, achieving the second step of securing the cleaning filter 72. Compared to traditional methods of securing the cleaning filter 72 using bolts, this reduces the time required to secure the cleaning filter 72 and facilitates subsequent disassembly and cleaning.

[0058] As another embodiment of the present invention, a U-shaped frame 41 is slidably arranged in the vertical direction inside the body 1, and the two top ends of the U-shaped frame 41 are respectively slidably arranged in the inclined grooves 44 opened on the two locking rods 43, and the U-shaped frame 41 pushes the ring sleeve 2 to move.

[0059] Specifically, such as Figure 11 As shown, a locking spring 45 is fixedly installed at the second end of the locking rod 43, and the first end of the locking spring 45 is fixedly installed on the base plate 22. When the ring 2 is in the low position, the locking spring 45 pushes the locking rod 43 so that the first end of the locking rod 43 is inserted into the locking groove 16, so that the ring 2 is locked and fixed on the machine body 1. Figure 2As shown, a main electric push rod 4 is fixedly installed inside the cavity 11, and a U-shaped frame 41 is fixedly installed on the output end of the main electric push rod 4.

[0060] Furthermore, when it is necessary to drive the ring 2 upward, the main electric push rod 4 pushes the U-shaped frame 41 upward. At this time, the two top ends of the U-shaped frame 41 slide along the inclined grooves 44 on the two locking rods 43 respectively. Then, by squeezing the inclined grooves 44, the two locking rods 43 are driven to slide respectively, so that the first ends of the two locking rods 43 are respectively disengaged from the locking grooves 16. At this time, the ring 2 and the machine body 1 are unlocked. Then, with the continued upward push of the U-shaped frame 41, the two pushers of the U-shaped frame 41 push against the bottom plate 22 respectively, thereby causing the ring 2 to move upward in the vertical direction.

[0061] After the cleaning filter 72 is replaced, the U-shaped frame 41 is driven down by the main electric push rod 4. At this time, the ring 2 begins to move down with the U-shaped frame 41 due to its own weight. Then, when the ring 2 is attached to the body 1 and the U-shaped frame 41 gradually disengages from the two locking rods 43, the two locking springs 45 push the locking rods 43 again so that the first end of the locking rod 43 is inserted into the locking groove 16, so that the ring 2 is locked and fixed on the body 1.

[0062] Furthermore, by using the main electric push rod 4 to drive the ring 2 to move while simultaneously enabling the locking rod 43 to slide and unlock, the use of a drive source is reduced, thus achieving both driving and unlocking of the ring 2.

[0063] As another embodiment of the present invention, a heating ring 3 is fixedly installed on the body 1 and sleeved on the outer wall of the ring 2, and a heating coil 31 fixedly installed on the inner wall of the heating ring 3 is located on the ventilation path of the air passage 12.

[0064] Specifically, such as Figure 2 As shown, the heating ring 3 is fixedly installed on the top of the body 1. A baffle 21 is provided on the top of the ring sleeve 2. When the ring sleeve 2 is in the low position, its bottom is attached to the body 1, and simultaneously, it is attached to the outer wall of the blower shroud 17. The bottom of the baffle 21 is attached to the top of the heating ring 3. By utilizing the ring sleeve 2, baffle 21, and heating ring 3 to cover the top air inlet of the air passage 12, as... Figure 2 The arrows indicate the direction of the blower. The blower 32 blows air into the ring 2. The blower air flows along multiple windows 23. The cleaning filter 72 on one side of the window 23 filters the air drawn in by the blower 32. The filtered blower air is then heated by the heating coil 31 on the inner wall of the heating ring 3. This heating removes some bacteria from the air. The heated blower air is then discharged along multiple air passages 12.

[0065] As the preferred embodiment provided by the present invention, the top of the body 1 is provided with movable slots 14 and air guide slots 13 arranged in a circular array, and humidification boxes 6 are slidably arranged in the movable slots 14 respectively, and multiple air guide slots 13 are respectively connected to the air passage slots 12.

[0066] Specifically, multiple air guide slots 13 are respectively matched with multiple air passage slots 12, and are connected to the air passage slots 12. Thus, when filtered air is discharged along the air passage slots 12, the air guide slots 13 guide the blower air, causing it to be discharged along the top of the air guide slots 13. Simultaneously, the multiple air guide slots 13 are located on one side of the multiple movable slots 14, such as... Figure 2 and Figure 12 As shown, the humidifier box 6 has a water storage chamber 61 inside, and a spray nozzle 63 connected to the water storage chamber 61 is fixedly installed on the humidifier box 6. Atomized water vapor is sprayed from the spray nozzle 63 to humidify the air. Since the air guide duct 13 is located on one side of the movable duct 14, when the blower air is discharged along the top of the air guide duct 13, compared to the spray nozzle 63 which is unaffected by the blower air, most of the water vapor will sink due to its own weight, leading to uneven indoor humidity. The blower air discharged from the top of the air guide duct 13 can drive some of the atomized water vapor to flow, thereby accelerating the diffusion of the water vapor.

[0067] As another embodiment of the present invention, the outer wall of the body 1 is provided with a plurality of side air vents 15 respectively connected to a plurality of air guide slots 13, and a plurality of louvers 8 are hinged in the side air vents 15, and a drive pipe 5 is rotatably provided in the body 1 to drive the plurality of louvers 8 to flip.

[0068] Specifically, the drive pipe 5 is rotatably disposed within the cavity 11, and multiple swing rods 54 matching the air passage 12 are fixedly installed on the outer wall of the drive pipe 5. Track grooves 81 are respectively opened on multiple louvers 8. Multiple uprights 56 matching the multiple louvers 8 are fixedly installed on the swing rods 54 and are movably disposed within the track grooves 81. Multiple swing rods 54 are movably disposed at the connection between the air guide 13 and the air passage 12.

[0069] In the default state, multiple louvers 8 are pressed together to cover the side air vents 15. At this time, most of the air flowing out along the air duct 12 will flow out along the top of the air guide duct 13. When it is necessary to expand the air blowing surface, the drive pipe 5 is driven to rotate so that the drive pipe 5 drives multiple swing rods 54 to swing. At this time, the multiple swing rods 54 drive multiple uprights 56 on them to slide in the track groove 81, thereby causing the multiple louvers 8 to flip. At this time, the flipping of the multiple louvers 8 releases the louvers 8 from covering the side air vents 15, so that most of the air blowing can flow out along the side air vents 15, and a part of the air blowing continues to flow out along the top of the air guide duct 13. Thus, the air blowing surface is expanded by using the side air vents 15 and the air guide duct 13, and the air blowing can be more evenly distributed to the indoor space around the machine body 1 to accelerate the air circulation in the room.

[0070] The drive tube 5 can be rotated by a motor; it can also be rotated by an electric push rod in conjunction with gears and racks; or any method known to those skilled in the art for driving the drive tube 5 to rotate.

[0071] As another embodiment of the present invention, the inner wall of the drive tube 5 is symmetrically provided with second curved guide grooves 52, and the two second curved guide grooves 52 are located on the moving path of the extension rods 42 symmetrically arranged on the U-shaped frame 41.

[0072] Specifically, such as Figure 5 As shown, mounting plates 51 are symmetrically fixedly installed on the outer wall of the drive tube 5. Reset springs 53 are fixedly installed on the two mounting plates 51 respectively. The first end of the reset spring 53 is fixedly installed on the body 1. By using the reset spring 53 to push the mounting plate 51, the mounting plate 51 is made to fit against the body 1. At this time, the top ends of the two second curved guide grooves 52 are located on the moving path of the two extension rods 42.

[0073] When the main electric push rod 4 drives the U-shaped frame 41 to move down and disengage from the two locking rods 43, the main electric push rod 4 continues to drive the U-shaped frame 41 to move down so that the two extension rods 42 on the U-shaped frame 41 slide to the top of the second curved guide groove 52 respectively. Then the two extension rods 42 continue to slide along the second curved guide groove 52 to make the drive tube 5 rotate. At this time, the return spring 53 is compressed and stored. At the same time, the rotation of the drive tube 5 drives multiple swing rods 54 to swing. At this time, multiple swing rods 54 drive multiple uprights 56 on them to slide in the track groove 81, thereby causing multiple louvers 8 to flip. At this time, the flipping of multiple louvers 8 makes the louvers 8 release the obstruction of the opposite side air vent 15.

[0074] Furthermore, by using the movement of the U-shaped frame 41 to drive the rotation of the drive tube 5, the use of the drive source can be reduced, and the curvature of the second curved guide groove 52 can be used to precisely control the rotation angle of the drive tube 5, thereby improving the flipping accuracy of the louver 8.

[0075] As another embodiment of the present invention, a curved air duct 62 is provided on the humidifier box 6, and the humidifier box 6 slides so that the first end of the curved air duct 62 is located on the blower path of the air passage 12, and the second end of the curved air duct 62 is located on the side of the spray nozzle 63 provided on the top of the humidifier box 6.

[0076] Specifically, such as Figure 12 As shown, a shield 64 is fixedly installed on the top of the humidifier box 6. The shield 64 covers the spray nozzle 63. At the same time, the second end of the curved air duct 62 is connected to the inner wall of one side of the shield 64 so as to be located on one side of the spray nozzle 63. The movable groove 14 is connected to the air passage groove 12.

[0077] Furthermore, by driving the humidifier box 6 to slide within the movable slot 14, the humidifier box 6 slides along the movable slot 14 into the air passage slot 12. At this time, part of the blower air in the air passage slot 12 flows along the curved air duct 62 on the humidifier box 6, and then some of the blower air flows out along the second end of the curved air duct 62 to accelerate the diffusion of water vapor from the spray nozzle 63. At the same time, under the heating of the air by the heating coil 31, the heated blower air can blow away the water droplets accumulated at the nozzle 63, thereby reducing the accumulation of water vapor in the shield 64. At the same time, the hot blower air can also accelerate the evaporation of water droplets, thereby improving the humidification effect.

[0078] The humidifier box 6 can slide by means of an electric push rod; or by means of a motor in conjunction with gears and racks; or by means of driving the humidifier box 6 to slide that are known to those skilled in the art.

[0079] As a further preferred embodiment of the present invention, a plurality of baffles 55 are fixedly installed on the outer wall of the drive tube 5 and movable within the air passage 12, and the humidification box 6 is movable on the guide plate 57 provided on the drive tube 5. The baffles 55 and the humidification box 6 slide to cover the air passage 12.

[0080] Specifically, such as Figure 13 As shown, multiple baffles 55 are fixedly installed on multiple swing rods 54, and multiple guide plates 57 are fixedly installed on multiple swing rods 54. Each guide plate 57 has a guide groove, which includes a first guide groove 58 and a second guide groove 59 that are interconnected. The second guide groove 59 is inclined toward the drive tube 5. The sliding rod 65 fixedly installed at the bottom of the humidification box 6 is slidably disposed in the first guide groove 58 and the second guide groove 59.

[0081] Furthermore, when it is necessary to replace the cleaning filter 72 on the ring 2, the main electric push rod 4 pushes the U-shaped frame 41 upward. At this time, the two top ends of the U-shaped frame 41 slide along the inclined grooves 44 on the two locking rods 43 respectively. Then, by squeezing the inclined grooves 44, the two locking rods 43 are driven to slide respectively, so that the first ends of the two locking rods 43 are respectively disengaged from the locking grooves 16. At this time, the ring 2 and the machine body 1 are unlocked. Then, with the continued upward push of the U-shaped frame 41, the two pushers of the U-shaped frame 41 push against the bottom plate 22 respectively, thereby causing the ring 2 to move vertically.

[0082] When the ring 2 moves vertically, the first ends of the two levers 19 move from the top to the bottom of the first curved guide groove 26, and the rotating block 25 rotates on the base plate 22. When the rotating block 25 rotates, it drives the push plate 28 to rotate, and the end of the push plate 28 slides away from the curved surface on the curved block 91. Then, after the tension spring 92 pushes the fastening rod 9 so that the protrusion 93 fits against the baffle 24, the fastening rod 9 and the ring 2 release the pressure and fixation on the cleaning filter 72. At the same time, the rotation of the rotating block 25 drives multiple arc rods 7 to rotate on the outer wall of the ring 2, and the multiple elastic strips 71 between the arc rods 7 and the baffle 24 gradually loosen from a taut state. Then, the elastic strips 71 release the pressure on the cleaning filter 72. At the same time, when the ring 2 is in the high position, the first ends of the two levers 19 are located at the bottom of the first curved guide groove 26, and the cleaning filter 72 is exposed for easy replacement.

[0083] Furthermore, by placing the new cleaning filter 72 between the baffle 24 and the ring 2, and placing the cleaning filter 72 on top of the arc-shaped rod 7, the side of the cleaning filter 72 extends beyond the top side of the arc-shaped rod 7. After the cleaning filter 72 is replaced, the U-shaped frame 41 is driven downward by the main electric push rod 4. At this time, the ring 2 begins to move downward with the U-shaped frame 41 due to its own weight. At this time, the first ends of the two levers 19 move from the bottom end to the top end of the first curved guide groove 26, and the rotating block 25 rotates again so that the ends of the multiple push plates 28 gradually approach the multiple curved blocks 91. At the same time, the arc-shaped rod 7 and the rotating block 25 rotate synchronously. The arc-shaped rod 7 moves along the outer wall of the ring 2. At this time, the elastic strip 71 is stretched and taut due to the rotation of the arc-shaped rod 7. Figure 7 and Figure 11As shown, at this time, the elastic strip 71 deforms and straightens, tightly adhering to the cleaning filter 72. The cleaning filter 72 is pushed by the elastic strip 71 to move closer to the outer wall of the ring 2. Then, multiple push plates 28 slide along the curved surface of the curved block 91 to squeeze the curved block 91 and make multiple fastening rods 9 slide. At this time, multiple protrusions 93 gradually adhere to multiple cleaning filters 72 and cooperate with the outer wall of the ring 2 to clamp and fix the cleaning filter 72 respectively. Furthermore, the elastic strip 71 pushes the cleaning filter 72 to further tighten the cleaning filter 72 to adhere to the ring 2, thereby improving the stability of the cleaning filter 72. Then, when the ring 2 is attached to the body 1 and the U-shaped frame 41 gradually disengages from the two locking rods 43, the two locking springs 45 push the locking rods 43 again so that the first end of the locking rods 43 is inserted into the locking groove 16, so that the ring 2 is locked on the body 1 and fixed. Then, the ring 2 moves vertically to facilitate the replacement and fixing of the cleaning filter 72.

[0084] like Figure 2 The arrows indicate the direction of the airflow. The blower 32 blows air into the ring 2, and the air flows along multiple windows 23. A cleaning filter 72 on one side of each window 23 filters the air drawn in by the blower 32. The filtered air is then heated by a heating coil 31 on the inner wall of the heating ring 3, thereby removing some bacteria from the air. The heated air then flows along multiple air ducts 12. Figure 8 and Figure 13 As shown, in the default state, multiple louvers 8 are attached to each other to cover the side air vents 15. At this time, most of the blower air flowing out along the air passage 12 will flow out along the top of the air guide 13.

[0085] When the blower surface needs to be enlarged, the main electric push rod 4 continues to drive the U-shaped frame 41 downward, causing the two extension rods 42 on the U-shaped frame 41 to slide to the top of the second curved guide groove 52. Then, the two extension rods 42 continue to slide along the second curved guide groove 52, causing the drive tube 5 to rotate. At this time, the return spring 53 is compressed and stores force, and the rotation of the drive tube 5 drives multiple swing rods 54 to swing, such as... Figure 9 As shown, at this time, multiple swing rods 54 respectively drive multiple uprights 56 to slide within the track groove 81, thereby causing multiple louvers 8 to flip. Simultaneously, the baffles 55 on the multiple swing rods 54 move synchronously with the swing rods 54 to partially cover the air passage 12, and as shown... Figure 13As shown, the guide plate 57 also moves synchronously with the swing rod 54, so that the slide rod 65 on the humidifier box 6 slides in the first guide groove 58. When it moves to the connection between the first guide groove 58 and the second guide groove 59, the main electric push rod 4 stops driving the U-shaped frame 41 to move down. When the slide rod 65 moves in the first guide groove 58, the humidifier box 6 remains in the movable groove 14 to prevent the humidifier box 6 from blocking the air duct 12. Because the multiple louvers 8 flip to release the louvers 8 from blocking the side air vents 15, most of the blower air can flow out along the side air vents 15, thereby expanding the blower surface.

[0086] When indoor humidification is required, the spray nozzle 63 on the humidifier box 6 is opened, and the main electric push rod 4 continues to drive the U-shaped frame 41 downward. At this time, the two extension rods 42 on the U-shaped frame 41 continue to slide downward along the second curved guide groove 52 to make the drive tube 5 continue to rotate. This causes the swing rod 54 to continue to move synchronously with the drive tube 5 and drive the guide plate 57 and the shield 55 to move. At this time, the sliding rod 65 on the humidifier box 6 slides into the second guide groove 59 along the connection between the first guide groove 58 and the second guide groove 59. When the sliding rod 65 slides into the second guide groove 59 and gradually approaches the drive tube 5, the humidifier box 6 gradually moves into the air passage 12 and shields the air passage 12. At the same time, the shield 55 also moves into the air passage 12 to shield the air passage 12. When the sliding rod 65 moves to the end of the second guide groove 59 near the drive tube 5, the humidifier box 6 is attached to the inner wall of one side of the air passage 12, and the shield... 55 is attached to the humidifier box 6, so that most of the air blown into the air passage 12 between the heating ring 3 and the ring sleeve 2 flows in along the first end of the curved air passage 62 and then flows out along the second end of the curved air passage 62. Since the second end of the curved air passage 62 is located on the side of the spray nozzle 63, the rapidly flowing air accelerates the diffusion of the atomized water vapor at the spray nozzle 63. At the same time, under the heating of the air by the heating coil 31, the heated air can blow away the water droplets accumulated at the nozzle of the spray nozzle 63, thereby reducing the accumulation of water vapor in the shield 64. At the same time, the hot air can also accelerate the evaporation of water droplets, thereby improving the humidification effect.

[0087] Furthermore, by simply driving the U-shaped frame 41 to move up and down in the vertical direction using the main electric push rod 4, the effects of moving and unlocking the drive ring sleeve 2, as well as driving the drive tube 5 to deflect and controlling the humidification box 6 and the louvered plate 8 to flip can be achieved, saving the use of the drive source and realizing the effect of switching between multiple air ducts.

[0088] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
