[0002] Currently, the air conditioning louvers on the market are generally installed at the air outlet or air inlet of the air conditioner. When the air conditioner is turned on, the louvers are opened to allow air in and out, and when the air conditioner is turned off, the louvers are closed to seal the air outlet or air inlet for protection.

[0003] Although existing technologies have incorporated UV devices at air conditioning vents for sterilization, such as the patent document "CN2505743Y Air Conditioning Fan with Ultraviolet Sterilization Function," which discloses an air conditioning fan with UV sterilization function, the fan comprises a louvered turbine and a volute. A UV light emitter, such as a UV lamp tube equipped with a protective lampshade, is fixed to the volute tube at the air outlet of the vortex chamber formed by the louvered turbine and the volute. This utility model provides an air conditioning fan with UV sterilization function that can directly and effectively kill microorganisms and bacteria in the air without causing harm to the human body.

[0004] However, the above patent has the following defects: the ultraviolet sterilization structure and the louver are set separately, and there is a lack of connection between the two, so the air flow channel between the louver blades cannot be directly sterilized; when the louver is opened, the ultraviolet sterilization structure cannot be directly delivered into the air flow channel, which may result in poor contact effect between the overall sterilization airflow and the sterilization structure.

[0040] See also Figures 1 to 10 As shown, an air conditioning shutter with an internal ultraviolet sterilization tube 15 includes a frame 1 and blades 2; the number of the blades 2 is several, and the several blades 2 are arranged at equal intervals along the vertical direction inside the frame 1, and are opened or closed by flipping between the several blades 2, wherein the frame 1 provides an overall installation position, and can be installed at the air inlet or outlet of the air conditioner through the frame 1; the left end circular tube 3 and the right end circular tube 4 are fixedly installed in the middle of the left and right ends of the blade 2 respectively, and the left end circular tube 3 and the right end circular tube 4 are fixedly installed in the middle of the left and right ends of the blade 2 respectively. The end circular tubes 4 are respectively rotatably mounted with a left end mounting seat 13 and a right end mounting seat 5. A plurality of circular holes are opened on the left and right sides of the frame 1. The left end circular tube 3 and the right end circular tube 4 respectively penetrate the circular holes on the left and right sides of the frame 1; the left end mounting seat 13 and the right end mounting seat 5 are respectively fixedly mounted on the left and right outer walls of the frame 1, thereby realizing the rotational mounting between the blade 2 and the frame 1. The circular tube design of the left end circular tube 3 and the right end circular tube 4 is used to drive the round rod 12 to pass through;

[0041] In a specific implementation, a synchronous drive assembly is installed on the left side of the frame 1, and the synchronous drive assembly includes a plurality of driving rods 12 that can rotate synchronously and in the same direction of rotation; the driving rod 12 passes through the left end circular tube 3, and the two are connected with a clearance fit, and the right end portion of the driving rod 12 is connected to the right end circular tube 4. When the driving rod 12 and the right end circular tube 4 are in a connected state, the synchronous drive assembly is used to synchronously drive multiple blades 2 to rotate together to achieve opening or closing; the driving rod 12 and the right end circular tube 4 are in a connected state, that is, the inclined iron block 29 is inserted in the triangular groove 30.

[0042] like Figure 3 As shown, in a specific implementation, the blade 2 is composed of a rear shell 201 and a front shell 202 fixedly connected. A plurality of UV sterilization tubes 15 with flippable angles are provided at the lower portion of the rear shell 201 of the blade 2, and the plurality of UV sterilization tubes 15 are arranged at equal intervals along the length direction of the blade 2. By providing the flippable UV sterilization tubes 15, after the blade 2 is opened, the UV sterilization tubes 15 are flipped so as to enter the gaps formed between adjacent blades 2, as shown in FIG. Figure 10 As shown, it can directly contact with the passing airflow to ensure the sterilization effect, increase the contact area of ​​direct light, and avoid the problem of insufficient sterilization effect caused by being too far away.

[0043] like Figures 1 to 2 As shown, as a specific technical solution, the synchronous drive assembly also includes a fixed side plate 6 fixedly mounted to the left side of the frame 1 and a drive motor 7 fixedly mounted on the fixed side plate 6, a first synchronous pulley 8 and a second synchronous pulley 9 are rotatably mounted on the plate surface of the fixed side plate 6; a first synchronous belt 10 is wound between the first synchronous pulley 8 and the second synchronous pulley 9; the middle part of one end of the first synchronous pulley 8 is fixedly connected to the output shaft end of the drive motor 7; a plurality of third synchronous pulleys 11 distributed at equal intervals are also rotatably mounted on the fixed side plate 6, and the plurality of third synchronous pulleys 11 are all meshed and connected with the inner ring wall of the first synchronous belt 10, and the third synchronous belt The middle part of one end of the wheel 11 is fixedly connected to one end of the driving rod 12; the diameter of the first synchronous pulley 8 is the same as the diameter of the second synchronous pulley 9, and the diameter of the third synchronous pulley 11 is smaller than the diameter of the first synchronous pulley 8. The first synchronous pulley 8 is driven to rotate by the driving motor 7. Combined with the design of the second synchronous pulley 9, the first synchronous belt 10 can be driven to move. The first synchronous belt 10 drives multiple third synchronous pulleys 11 to rotate in the same direction and synchronously. When the driving rod 12 is in a connected state with the right end circular tube 4 and the insert 24 is not blocked by the fan-shaped groove 23, all the blades 2 in the frame 1 can be rotated together to open or close.

[0044] The driving motor 7 can be a servo motor, which can be driven to rotate at any angle.

[0045] like Figures 7 to 8As shown, as a specific technical solution, the right end of the driving rod 12 is inserted into the interior of the right end circular tube 4, and four concave holes 27 distributed in a ring array are opened on the cylindrical surface of the right end of the driving rod 12. The four concave holes 27 are all connected with a ramp iron block 29 with clearance fit, and a spring 28 is provided inside the concave hole 27. One end of the spring 28 is fixedly connected to the hole wall of the concave hole 27, and the other end of the spring 28 is fixedly connected to one end of the ramp iron block 29, and the end of the ramp iron block 29 away from the spring 28 is straight. angular structure; the inner wall of the right end circular tube 4 is provided with four triangular grooves 30 adapted to the right-angled ends of the bevel iron block 29, and a permanent magnet 31 is fixedly mounted on the inner wall of the right end circular tube 4, and one surface of the permanent magnet 31 fits in with the bevel of the triangular groove 30; the right outer wall of the frame 1 is provided with a fan-shaped groove 23 with a central angle of 30-40 °, the center of the fan-shaped groove 23 is located on the axis of the right end circular tube 4, and an insert 24 is fixedly mounted on the outer wall of the right end circular tube 4, and the insert 24 is located inside the fan-shaped groove 23;

[0046] like Figure 7 As shown, the insert 24 is in the position where the shutter blades 2 are closed. Figure 8 It is shown as Figure 7 A schematic cross-sectional view of the right end tube 4 and the driving rod 12 in this state, where the driving rod 12 and the right end tube 4 are connected, and the right-angled end of the inclined iron block 29 is embedded in the triangular groove 30;

[0047] During the opening process of the shutter, the driving rod 12 drives the right end tube 4 to rotate, specifically causing the top of the blade 2 to turn inward and the bottom of the blade 2 to turn outward, turning from a vertical state to a vertical state. Figure 10 state; in the above process, Figure 8 As shown, the driving rod 12 rotates clockwise. Since the permanent magnet 31 and the inclined iron block 29 are in a magnetic attraction state and are limited, the driving rod 12 can drive the right end tube 4 to rotate together. At the same time, the insert 24 moves in the fan-shaped groove 23. After it moves to the groove wall of the fan-shaped groove 23, it is blocked. At this time, the blade 2 completes opening, specifically moving to the groove surface of the fan-shaped groove 23 with the second conductive contact 26;

[0048] Due to the obstruction, the right end tube 4 cannot continue to rotate with the driving rod 12, and the driving rod 12 continues to rotate a certain angle to drive the ultraviolet sterilization tube 15 to flip, such as Figure 8The inclined surface of the inclined iron block 29 shown in the figure contacts and squeezes the inclined surface of the triangular groove 30, causing the inclined iron block 29 to move deeper into the concave hole 27, while compressing the spring 28 without affecting the rotation of the driving rod 12. By driving the driving rod 12 to continue to rotate a certain angle, the ultraviolet sterilization tube 15 is provided with a flip drive, so that the ultraviolet sterilization tube 15 enters the air flow channel between the two adjacent blades 2, and directly enters to achieve ultraviolet sterilization;

[0049] When the shutter is closed, the driving rod 12 is rotated in the direction opposite to the above-mentioned rotation direction. The inclined iron block 29 is first not attracted by the permanent magnet 31. The inclined iron block 29 is in contact with the inner wall of the right end circular tube 4 due to the elastic force of the spring 28. The friction between the inclined iron block 29 and the inner wall of the right end circular tube 4 is insufficient to rotate the right end circular tube 4 together with the driving rod 12. As a result, the ultraviolet sterilization tube 15 is driven to rotate first and then stored in the installation groove 14. With this design, the ultraviolet sterilization tube 15 is reset and turned over first, avoiding blocking the blade 2 from turning and resetting.

[0050] After the UV sterilizing tube 15 is reset, the inclined iron block 29 is aligned with the triangular groove 30 and is embedded in the triangular groove 30 by the elastic force of the spring 28. Figure 8 As shown, the driving rod 12 continues to reverse, and through the inclined iron block 29, the driving rod 12 can drive the right end tube 4 to reverse, so that the blade 2 is reset until the blade 2 is vertical, and the closing is completed; after resetting, the block 24 and the fan-shaped groove 23 are away from the surface contact block of the second conductive contact 26, and further rotation and flipping after resetting cannot be performed.

[0051] In a specific implementation, two second conductive contacts 26 for an external power supply are provided on the groove wall of the fan-shaped groove 23, and two first conductive contacts 25 are provided on the insert 24. The two first conductive contacts 25 are electrically connected to the multiple ultraviolet sterilization tubes 15 on a single blade 2 through the wire 1501. After the blade 2 is flipped and opened, the insert 24 contacts the fan-shaped groove 23, specifically through the second conductive contacts 26 contacting the first conductive contacts 25, so that the external power supply is connected to the ultraviolet sterilization tube 15 and energized;

[0052] The multiple UV sterilizing tubes 15 on the single blade 2 are connected in parallel via the wire 1501 to form a parallel circuit. When the first conductive contact 25 is not in contact with the second conductive contact 26, the circuit is in an open state. When the first conductive contact 25 is in contact with the second conductive contact 26, power is supplied.

[0053] like Figure 6 As shown, the wire 1501 is left with sufficient length in the installation slot 14 to avoid affecting the flipping drive of the ultraviolet sterilization tube 15.

[0054] The power on and off is realized by the movement of the insert 24 in the fan-shaped groove 23 and further realized by the rotation and opening and closing of the blade 2; thereby realizing the automatic power on and off of the ultraviolet sterilization tube 15.

[0055] As a specific technical solution, Figure 6 As shown, a plurality of equally spaced mounting grooves 14 are provided at the lower portion of the rear shell 201, and a groove 21 is further provided at the lower portion of the rear shell 201, the ultraviolet sterilization tube is embedded in the interior of the mounting groove 14, a rotating shaft 20 is installed inside the shell wall of the rear shell 201, and the rotating shaft 20 passes through the plurality of mounting grooves 14 and the groove 21, and a fixed carrier 18 is fixedly installed at one end of the mounting groove 14 away from the middle of the blade 2, and the fixed carrier 18 is rotatably installed with the rotating shaft 20, and an end of the ultraviolet sterilization tube close to the fixed carrier 18 is fixedly connected to a hinge seat 19, and the hinge seat 19 is fixedly connected to the rotating shaft 20; the portion of the rotating shaft 20 located in the groove 21 A fifth synchronous pulley 22 is fixedly sleeved on the driving rod 12, and a fourth synchronous pulley 16 is fixedly sleeved on the driving rod 12. A second synchronous belt 17 is wound between the fourth synchronous pulley 16 and the fifth synchronous pulley 22; the diameter of the fourth synchronous pulley 16 is larger than the diameter of the fifth synchronous pulley 22; the rotation installation of the ultraviolet sterilization tube 15 in the mounting groove 14 is realized by the rotating shaft 20. Under the premise that the blade 2 does not rotate, the driving rod 12 rotates alone, which can drive the fourth synchronous pulley 16 to rotate. Through the transmission action of the second synchronous belt 17, the fifth synchronous pulley 22 can be rotated, thereby driving the rotating shaft 20 to rotate, so that the ultraviolet sterilization tube 15 rotates and flips;

[0056] When the ultraviolet sterilization tube 15 is turned over and enters between the adjacent blades 2, the ultraviolet sterilization tube 15 is rotated and turned over 90 degrees. Figure 10 As shown; when resetting, the ultraviolet sterilization tube 15 is flipped and received into the mounting groove 14;

[0057] The diameter of the fourth synchronous pulley 16 is greater than that of the fifth synchronous pulley 22 , and after transmission, the fourth synchronous pulley 16 is added. When the round rod 12 is driven to rotate a small angle, the rotating shaft 20 is rotated a larger angle for flipping.

[0058] The benefit of the present application lies in that: the present application proposes an air conditioning louver with an internal ultraviolet sterilization tube 15, wherein the ultraviolet sterilization tube 15 is added to the blades 2 of the air conditioning louver, so that the louver has a sterilization function, which can sterilize the airflow passing through, thereby reducing the bacteria and pathogens in the air inlet or outlet of the air conditioner;

[0059] Furthermore, the ultraviolet sterilization tube 15 adopts a flip-adjustable design. When the air-conditioning louver is closed, it is stored against the inner side of the blade 2, specifically in the mounting groove 14 on the rear housing 201 of the blade 2. At the same time, the blade 2 is closed to provide protection and shielding. When the air-conditioning louver is open and air is admitted, it is unfolded by flipping, and the ultraviolet sterilization tube 15 enters the air flow channel between two adjacent blades 2. The arrangement of multiple equally spaced ultraviolet sterilization tubes 15 on a single blade 2 greatly increases the contact area of ​​sterilization irradiation, ensures the contact effect between the air flow in the air flow channel and the ultraviolet sterilization tube 15, and ensures the sterilization effect.

[0060] Furthermore, the UV sterilization tube 15 adopts an automatic power on and off design. When the shutter is opened, the UV sterilization tube 15 can be automatically powered on. When the shutter is closed, the UV sterilization tube 15 can be automatically powered off, realizing automatic opening and closing without additional operation.

[0061] Finally, the opening and closing of the shutters and the rotation and adjustment angle of the ultraviolet sterilization tube 15 can be driven by a single power source, without the need to set up multiple additional driving power structures, thus avoiding waste of power sources.

[0062] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
