[0002] Currently, UVLED air sterilization is widely used. However, in the fresh air system of the air conditioning duct of rail transit vehicles, since the cross-sectional area and fresh air flow of the fresh air duct are usually large, it is difficult to completely cover the fresh air duct for sterilization by directly placing UVLED air sterilizers in the fresh air duct. At the same time, if the fresh air duct is filled with UVLED air sterilizers, there is a risk of clogging the fresh air duct. Summary of the Invention

[0003] In view of this, it is necessary to provide a sterilization and bacteriostatic device for fresh air in the air conditioning duct of rail transit vehicles, so as to sterilize and inhibit the air entering the fresh air duct without blocking the fresh air duct.

Detailed Implementation

[0025] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0026] Please refer to Figures 1-3 The present invention provides a sterilization and bacteriostatic device for fresh air in the air conditioning duct of rail transit vehicles, including a sterilization mechanism 1 and a reciprocating movement mechanism 2.

[0027] The sterilization mechanism 1 includes an assembly 11 and a UVCLED component 12. The length of the UVCLED component 12 is adapted to the width of the air conditioning duct of the rail transit vehicle. The UVCLED component 12 is fixed inside the assembly 11.

[0028] The reciprocating moving mechanism 2 is connected to the assembly 11 and is used to drive the assembly 11 to reciprocate along a direction perpendicular to the width of the rail transit vehicle's air conditioning duct.

[0029] During installation, the mounting component 11 is installed inside the air conditioning duct of the rail transit vehicle, so that the effective range of the UVCLED component 12 can cover the entire width of the air conditioning duct. During use, the mounting component 11 is driven to move back and forth in a direction perpendicular to the width of the air conditioning duct by the reciprocating moving mechanism 2, so that the effective range of the UVCLED component 12 can cover the entire length of the air conditioning duct, thereby achieving full coverage of the entire air conditioning duct and sterilizing and inhibiting the bacteria in the air entering the fresh air duct without blocking the fresh air duct.

[0030] To implement the specific functions of assembly 11, please refer to... Figures 2-5, in a preferred embodiment, the fitting 11 includes a heat dissipation base 111 and a cover plate 112. A receiving groove 1111 for receiving the UVC LED component 12 is formed on the heat dissipation base 111. A placing groove 1112 located outside the receiving groove 1111 is also formed on the heat dissipation base 111. The cover plate 112 is disposed in the placing groove 1112 and is made of quartz material, so as to facilitate the ultraviolet light emitted by the UVC LED component 12 to pass through.

[0031] For the specific realization of the fixation of the cover plate 112, please refer to Figures 2-5 , in a preferred embodiment, a bonding layer 113 is provided between the cover plate 112 and the bottom surface of the placing groove 1112. In this embodiment, the bonding layer 113 is a back glue.

[0032] For the further fixation of the cover plate 112, please refer to Figures 2-5 , in a preferred embodiment, two clamping grooves 1113 are further formed on the heat dissipation base 111. The fitting 11 further includes two pressing strips 114. One ends of the two pressing strips 114 are respectively clamped in the two clamping grooves 1113, and the other ends of the two pressing strips 114 are respectively pressed on both ends of the cover plate 112. During installation, after the cover plate 112 is installed, the pressing strips 114 are inserted into the clamping grooves 1113 along the length direction. The pressing strips 114 can press the edges of the cover plate 112 to improve the fastening property of the cover plate 112, and at the same time can also hide the gaps at the edges of the cover plate 112 to improve the aesthetics.

[0033] For the fixation of the pressing strips 114, please refer to Figures 2-5 , in a preferred embodiment, the fitting 11 further includes two end caps 115. The two end caps 115 are respectively fixed at both ends of the heat dissipation base 111 and are respectively abutted against both ends of the pressing strips 114, so as to limit both ends of the pressing strips 114 and prevent the pressing strips 114 from disengaging from the clamping grooves 1113.

[0034] For the specific realization of the connection between the end cap 115 and the heat dissipation base 111, please refer to Figures 2-5 , in a preferred embodiment, fixing screw holes 1114 are formed at both ends of the heat dissipation base 11, a first让位孔 1151 is formed on the end cap 115, and the fitting 11 further includes fixing screws 116. The fixing screws 116 pass through the first让位孔 1151 and are threadedly connected with the fixing screw holes 1114, so as to realize the fixed connection between the end cap 115 and the heat dissipation base 111.

[0035] For the protection of the UVC LED component 12, please refer to Figures 2-5, in a preferred embodiment, the UVC LED component 12 includes a PCB board 121 and a plurality of lamp beads 122 fixed on the PCB board 121. The PCB board 121 is embedded in the accommodation groove 1111. A limiting groove 1115 is formed on the inner bottom surface of the accommodation groove 1111. A plurality of second relief holes are formed on the PCB board 121 and are adapted to the limiting groove 1115. The fitting 11 further includes a plurality of limiting posts 117. One end of the limiting post 117 is embedded in the limiting groove 1115, and the other end of the limiting post 117 passes through the second relief hole and abuts against the cover plate 112. By providing the limiting posts 117, the cover plate 112 can be supported to prevent the cover plate 112 from contacting the lamp beads 122, thereby protecting the lamp beads 122.

[0036] To specifically implement the function of the reciprocating movement mechanism 2, please refer to Figure 2 、 Figure 6 and Figure 7 , in a preferred embodiment, the reciprocating movement mechanism 2 includes a fixed seat 21, two mounting seats 22, a lead screw 23, a slider 24, a first connecting plate 25, a second connecting plate 26 and a rotation driving motor 27. A sliding groove 211 is formed on the fixed seat 21. The two mounting seats 22 are respectively fixed at both ends of the fixed seat 21. Both ends of the lead screw 23 are rotatably connected to the two mounting seats 22. The slider 24 is threadedly rotatably connected to the lead screw 23. The slider 24 is slidably disposed in the sliding groove 211. The first connecting plate 25 is fixed to the slider 24. One end of the second connecting plate 26 is fixedly connected to the first connecting plate 25, and the other end of the second connecting plate 26 is fixedly connected to the heat dissipation base 111. The rotation driving motor 27 is connected to the lead screw 23 and is used to drive the lead screw 23 to rotate. During installation, the fixed seat 21 is fixed on the top plate of the rail transit vehicle-mounted air-conditioning duct. Correspondingly, a fixing piece 212 is fixed on the fixed seat 21, so as to facilitate the fixing of the fixed seat 21. During use, the rotation driving motor 27 drives the lead screw 23 to rotate. The lead screw 23 acts on the slider 24. Since the slider 24 is limited by the sliding groove 211 and cannot rotate, the rotation of the lead screw 23 is converted into the movement of the slider 24. The slider 24 drives the first connecting plate 25, the second connecting plate 26 and the heat dissipation base 111 to move. The reciprocating movement of the slider 24 can be realized by periodically changing the rotation direction of the rotation driving motor 27.

[0037] To achieve the automatic commutation of the reciprocating movement mechanism 2, please refer to Figure 2 、 Figure 6 and Figure 7, in a preferred embodiment, the reciprocating movement mechanism 2 further includes two positioning members 28 and a commutator. The positioning member 28 includes a nut 281 and a microswitch 282. The two nuts 281 are threadedly rotatably connected to both ends of the screw rod 23 and are located on both sides of the slider 24. The microswitch 282 is fixed to the nut 281. The microswitch 282 is electrically connected to the commutator, and the commutator is electrically connected to the rotation drive motor 27. When the slider 24 abuts against the contact of any one of the microswitches 282, the commutator operates and changes the rotation direction of the rotation drive motor 27. During specific installation, the constructor only needs to rotate the two nuts 281 to appropriate positions to complete the installation. In the prior art, usually, the constructor needs to customize the operation parameters of the motor to achieve reciprocating motion, and the setting of the motor operation parameters is difficult for general constructors. In the present invention, there is no need for the constructor to set the operation parameters of the motor. Only by moving the two nuts 281 to appropriate positions can the automatic commutation of the reciprocating movement mechanism 2 be achieved.

[0038] For the specific implementation of the connection between the rotation drive motor 27 and the screw rod 23, please refer to Figure 2 , Figure 6 and Figure 7 , in a preferred embodiment, the reciprocating movement mechanism 2 further includes a driving gear 291 and a driven gear 292. The driving gear 291 is fixedly sleeved on the output shaft of the rotation drive motor 27, and the driven gear 292 is fixedly sleeved on the screw rod 23. The driven gear 292 meshes with the driving gear 291.

[0039] To better understand the present invention, the following is a detailed description of the working process of the rail transit vehicle-mounted air-conditioning duct fresh air sterilization and antibacterial device provided by the present invention in conjunction with Figures 1-7 : During installation, the fitting 11 is installed in the rail transit vehicle-mounted air-conditioning duct so that the action range of the UVC LED component 12 can cover the entire width of the vehicle-mounted air-conditioning duct. During use, the reciprocating movement mechanism 2 drives the fitting 11 to reciprocate in a direction perpendicular to the width of the rail transit vehicle-mounted air-conditioning duct, so that the action range of the UVC LED component 12 can cover the entire length of the vehicle-mounted air-conditioning duct, thereby achieving full coverage of the entire vehicle-mounted air-conditioning duct, and sterilizing and antibacterial the air entering the fresh air channel without blocking the fresh air channel.

[0040] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
