[0010] The first gear is fixed to the outer wall of the shaft connected to the output end of the drive motor. The outer wall of the first gear meshes with a second gear that is rotatably connected to the inner cavity of the air outlet cover. The second gear provides a lateral moving thrust to the end of the push rod through a stop block fixed to the outer wall shaft.
[0011] The push rod is laterally slidably installed in the inner cavity of the air outlet cover. The push rod is used to push the transmission rod rotatably connected at its end to move synchronously. The protruding part at the top of the push rod is sleeved with a positioning rod that is fixed to the inner wall of the air outlet cover. A spring is surrounded on the outside of the positioning rod to push the push rod to move laterally and reset.
[0012] As a further embodiment of this utility model: the adjustment unit includes a transmission rod, an eccentric block, and a guide plate;
[0013] The transmission rod drives the guide plate to rotate through an eccentric block rotatably connected to its end. The rectangular eccentric block is fixedly connected to the guide plate shaft at its end, and the eccentric block is laterally distributed at the top of the guide plate.
[0014] As a further improvement of this utility model, the number of eccentric blocks and guide plates is three, and the three guide plates are evenly distributed in the air outlet cavity of the blower.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-4 In this embodiment of the utility model, an air direction adjustment mechanism based on an air purifier and sterilizer includes an air inlet housing 1 and an air outlet cover 2 fixed to the top of the air inlet housing 1 for the installation of a blower 4. It also includes a filter screen 3 installed inside the air inlet housing 1 and extending to the inner side of the partition between the air inlet housing 1 and the air outlet cover 2. The top of the blower 4 is equipped with a drive motor 5 connected to the top of the impeller shaft in the inner cavity of the blower 4. The drive motor 5 is used to provide power for the operation of the blower 4. It also includes an adjustment mechanism 6 installed on the air outlet cover 2 and the drive motor 5 for adjusting the blowing force.
[0026] The adjustment mechanism 6 includes a transmission unit and an adjustment unit;
[0027] The transmission unit is used to provide power for the movement of the adjustment unit;
[0028] The adjustment unit is used to adjust the direction of the blown air.
[0029] The transmission unit includes a first gear 601, a second gear 602, a stop block 603, a push rod 604, a positioning rod 605, and a spring 606;
[0030] The first gear 601 is fixed to the outer wall of the shaft connected to the output end of the drive motor 5. The outer wall of the first gear 601 meshes with the second gear 602, which is rotatably connected to the inner cavity of the air outlet cover 2. The second gear 602 provides a lateral moving thrust to the end of the push rod 604 through the abutment 603 fixed to the shaft on the outer wall.
[0031] The push rod 604 is slidably installed in the inner cavity of the air outlet cover 2. The push rod 604 is used to push the transmission rod 607, which is rotatably connected at the end, to move synchronously. The top protrusion of the push rod 604 is sleeved with a positioning rod 605 that is fixed to the inner wall of the air outlet cover 2. The outer side of the positioning rod 605 is surrounded by a spring 606 that pushes the push rod 604 to move laterally and reset.
[0032] The adjustment unit includes a transmission rod 607, an eccentric block 608, and a guide plate 609;
[0033] The transmission rod 607 drives the guide plate 609 to rotate through the eccentric block 608 rotatably connected to its end. The rectangular eccentric block 608 is fixedly connected to the shaft of the guide plate 609 at its end, and the eccentric block 608 is laterally distributed at the top of the guide plate 609.
[0034] In this embodiment: by starting the drive motor 5, the drive motor 5 will drive the impeller connected to the output end to rotate, thereby drawing outside air into the interior of the filter screen 3 through the air inlet housing 1, purifying the air through the filter screen 3, and the purified air is discharged through the air outlet of the air outlet cover 2 through the air duct of the blower 4, thus completing the purification of the air.
[0035] When the drive motor 5 is working, the shaft connected to the output end of the drive motor 5 rotates synchronously, driving the first gear 601 fixed on the outer wall of the shaft to rotate. The first gear 601 provides a rotational thrust to the second gear 602. The second gear 602, which is subjected to force, will synchronously drive the stop block 603 fixed on the outer wall of the shaft to rotate circumferentially. The semi-circular stop block 603 provides a lateral moving thrust to the push rod 604. The push rod 604, subjected to external force, will move along the outer wall of the positioning rod 605 and be subjected to the compressive force of the spring 606. At the same time, the transmission rod 607, which is rotatably connected to the end of the push rod 604, will also be affected. The guide plate 609 will also move as the push rod 604 moves laterally. The multiple eccentric blocks 608 rotatably connected to the end of the transmission rod 607 are simultaneously pushed and drive the guide plate 609 to rotate. When the stop block 603 no longer contacts the end of the push rod 604, the push rod 604 is reset under the action of the spring 606, so that the guide plate 609 is reset synchronously, thus completing the purpose of automatically adjusting the angle of the exhaust air without manual adjustment, avoiding the situation where the wind blows directly on people and causes them to feel uncomfortable. It should be noted that the drive motor 5 is fixedly connected to the top of the inner cavity of the air outlet cover 2 through a support frame.
[0036] Please refer to this carefully. Figures 1-4 There are three eccentric blocks 608 and guide plates 609. The three guide plates 609 are evenly distributed in the air outlet cavity of the blower 4. The transmission rod 607 is connected to three lateral rods at one end near the eccentric block 608. The inner cavity of the air outlet cover 2 is formed with a sliding groove for the push rod 604 to move laterally. The outer wall of the abutment block 603 is generally semi-circular.
[0037] In this embodiment: With this structure, under the action of the three lateral rods of the transmission rod 607, the transmission rod 607 is pushed by the push rod 604. The transmission rod 607 moves laterally and tilts at the same time, thereby pushing the three eccentric blocks 608 and guide plates 609 rotatably connected at the ends of the three lateral rods to rotate. This causes the guide plates 609, which are vertically distributed at the air outlet, to tilt, thereby adjusting the direction of the blown air.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
