[0038] Embodiment 2

[0039] On the basis of embodiment 1, the present invention is as follows Figure 2-Figure 4 As shown, a positioning seat 9 is fixedly installed on the left end of the back of the housing 6, and positioning slots 14 are provided on both the left and right ends of the back of the positioning seat 9. L-shaped limiting ears 10 are provided on both the left and right ends of the back of the positioning seat 9, and arc-shaped spring pieces 13 are fixedly connected to both ends of the inner side of the L-shaped limiting ear 10. A constant current power supply 7 is provided on the inner side of the L-shaped limiting ear 10, and positioning blocks 12 are fixedly connected to both the left and right ends of the front of the constant current power supply 7.

[0040] The middle end of the back of the positioning seat 9 is bonded with a seismic isolation pad 11, and the back of the seismic isolation pad 11 is in contact with the constant current power supply 7;

[0041] Through the above technical solution Figure 2-Figure 4 As shown, by setting the seismic isolation pad 11, the vibration force during operation can be reduced to ensure the normal operation of the constant current power supply 7.

[0042] The positioning block 12 is adapted to the positioning slot 14 , and the positioning block 12 is engaged with the inner side of the positioning slot 14 .

[0043] Through the above technical solution Figure 2-Figure 4 As shown, by providing the positioning block 12 and the positioning slot 14 , the constant current power supply 7 can be easily disassembled, assembled and maintained.

[0044] The technical solution drives the constant current power supply 7 to move and makes the two ends below enter the L-shaped limiting ear 10 through the setting of the positioning seat 9, which will cause the arc-shaped spring piece 13 to contract. When the constant current power supply 7 moves to the middle end of the positioning seat 9, the constant current power supply 7 is relaxed, and the arc-shaped spring piece 13 is reset by tension, and can drive the positioning block 12 to be inserted into the positioning slot 14, and make the constant current power supply 7 and the isolation pad 11 contact, thereby realizing the rapid installation of the constant current power supply 7. Conversely, the constant current power supply 7 is driven to move outward, and the arc-shaped spring piece 13 is contracted again. At the same time, the positioning block 12 withdraws from the positioning slot 14, and then the constant current power supply 7 is driven to withdraw from the L-shaped limiting ear 10.

[0045] Working principle: The device can be installed on the air conditioner in the use environment through the installation brackets 3 at both ends to disinfect and sterilize the mixed air and filter in the air conditioner. Its main structure is a shell 6, which is roughly in the shape of a rectangular parallelepiped and is made of aluminum alloy. At the same time, the heat of the product when the lamp beads are working is dissipated. A constant current power supply 7 and a time relay 8 are installed on the back of the shell 6. Through the setting of the constant current power supply 7, it has functional grounding, built-in active PFC function and lightning protection circuit, and adopts a temperature control system to extend the service life of the power supply. The on and off time of the circuit can be strictly controlled by the time relay 8, and the disinfection time can be flexibly adjusted according to actual conditions. The two ends of the shell 6 are connected to the installation bracket 3, and there is a sealing pad 4 in the middle of the connection to achieve a sealing effect inside to prevent water from penetrating into the mixed air. The UVCled lamp bead panel 5 provides a light disinfection source, which can disinfect the mixed air. The air and air conditioning filter are disinfected, thereby effectively avoiding secondary infection and inhibiting the spread of infectious diseases. The setting of the frame strip 1 can compress and limit the UVCled lamp bead panel 5 and the quartz glass 2. Through the setting of the positioning seat 9, the constant current power supply 7 is driven to move and the two ends below enter the L-shaped limiting ear 10, which will cause the arc-shaped spring piece 13 to shrink. When the constant current power supply 7 moves to the middle end of the positioning seat 9, the constant current power supply 7 is relaxed, and the arc-shaped spring piece 13 is reset by tension, and can drive the positioning card block 12 to be inserted into the positioning card slot 14, and make the constant current power supply 7 and the isolation pad 11 contact, thereby realizing the rapid installation of the constant current power supply 7. On the contrary, the constant current power supply 7 is driven to move outward, and the arc-shaped spring piece 13 is shrunk again. At the same time, the positioning card block 12 withdraws from the positioning card slot 14, and then the constant current power supply 7 is driven to withdraw from the L-shaped limiting ear 10.
