The ultraviolet lamp panels include aluminum-based lamp panels 113 that can reflect ultraviolet rays onto the photocatalyst honeycomb mesh panel 202. Along the arrangement direction of the ultraviolet lamp panels, ultraviolet lamps 111 and LED lamps 112 are provided on the same side of each aluminum-based lamp panel 113. In this embodiment, the aluminum-based light panel 113 is provided with a plurality of ultraviolet lamps 111 and a plurality of LED lamps 112. The ultraviolet lamps 111 and the LED lamps 112 are both integrated on the aluminum-based light panel 113 by patch processing. The ultraviolet lamps 111 and the LED lamps 112 are arranged alternately on the aluminum-based light panel 113. The LED lamps 112 are mainly used to assist in activating the photocatalyst on the photocatalyst honeycomb mesh panel 202. The LED lamps 112 are more energy-efficient than the ultraviolet lamps 111. The bottom shell 101 and the panel 203 are fixedly connected by screws. The lamp panel assembly 110 is bonded to the bottom shell 101.

[0031] The lamp board assembly 110 also includes a control board 115 (PCB board), a first bus PCB board 116, and a connecting wire 102 for electrically connecting to an external circuit. The connecting wire 102 is electrically connected to the control board 115, and the connecting wire 102 extends out of the bottom shell 101, perpendicular to the arrangement direction of the ultraviolet lamp board.

On the side facing the second busbar PCB board 114, each of the aluminum-based lamp boards 113 is provided with a plurality of ultraviolet lamps 111 and a plurality of LED lamps 112.

[0033] In this embodiment, a plurality of assembly openings are formed on both the control board 115 and the first busbar PCB board 116. Each of the assembly openings is evenly spaced along the arrangement direction of the ultraviolet lamp boards, so that the ultraviolet lamp boards are arranged at equal intervals.

[0034] In this embodiment, specifically, the photocatalyst honeycomb mesh plate 202 is disposed closely adjacent to the lamp board assembly 110. A first shock-absorbing foam 201 is pasted on the edge of the photocatalyst honeycomb mesh plate 202 facing the lamp board assembly 110. The first shock-absorbing foam 201 is located between the lamp board assembly 110 and the photocatalyst honeycomb mesh plate 202 to prevent the lamp board assembly 110 and the photocatalyst honeycomb mesh plate 202 from colliding with each other due to vibration after the air sterilization module is assembled, which may cause product damage. The first shock-absorbing foam 201 is in a narrow strip shape. In this embodiment, four first shock-absorbing foams 201 are used. In this embodiment, the outer periphery of the air sterilization module is coated with a second shock-absorbing foam 3 (the second shock-absorbing foam 3 coats the outer peripheries of the bottom case 101 and the panel 203), and the second shock-absorbing foam 3 plays a shock-absorbing role, and the connecting wire 102 extends out of the second shock-absorbing foam 3.

[0035] In this embodiment, specifically, the lamp board assembly 110 is fixed in the assembly cavity of the bottom case 101 through a black curing glue (the entire lamp board assembly 110 is received in the bottom case 101) to prevent the lamp board assembly 110 from shaking in the bottom case 101. The bottom case 101 is in a rectangular frame shape, and a first through hole for air to pass through is formed in the middle of the bottom case 101. The lamp board assembly 110 faces the first through hole, and air enters through the first through hole and then blows towards the second sterilization assembly 2 after passing through the lamp board assembly 110.

[0036] In this embodiment, both the first busbar PCB 116 and the second busbar PCB 114 function as busbars. The positive current is input through the positive wire on the connection wire 102, and after passing through the control board 115, it is shunted to the ultraviolet lamps 111 and LED lamps 112 on each ultraviolet lamp board. The negative electricity of the ultraviolet lamp board is output through the first busbar PCB 116 to the second busbar PCB 114, and then returns to the control board 115 through the second busbar PCB 114. The control board 115 outputs through the negative wire on the connection wire 105 to form a complete loop.

[0037] The vehicle end controls the turning on or off of the ultraviolet lamp 111 and the LED lamp 112, and the ultraviolet lamp 111 and the LED lamp 112 are activated by the positive current input through the control board 115.

[0038] In this embodiment, specifically, the photocatalyst honeycomb mesh plate 202 is a titanium dioxide type photocatalyst honeycomb mesh plate. The photocatalyst honeycomb mesh plate 202 is fixed in the installation cavity of the panel 203 by 3M adhesive (the entire photocatalyst honeycomb mesh plate 202 is housed inside the panel 203). The panel 203 is in the shape of a rectangular frame, and the boundary dimensions are slightly smaller than the bottom case 101. The bottom case 101 covers the entire panel 203, that is, the entire panel 203 is housed inside the bottom case 101. In this embodiment, the bottom case and the panel are fixedly connected by 12 self-tapping screws. A second through hole for air to pass through is provided in the middle of the panel 203. The photocatalyst honeycomb mesh plate 202 faces the second through hole, and the second through hole is communicated with the first through hole. Air enters the air sterilization module from the first through hole and then passes through the lamp board assembly 110 and the photocatalyst honeycomb mesh plate 202 in sequence and blows out of the air sterilization module from the second through hole.

[0039] Embodiment 2 of the present utility model provides an automotive air conditioner, including an air inlet, and further including the air sterilization module of the above-mentioned automotive air conditioner. The air sterilization module of the automotive air conditioner is installed at the air inlet of the automotive air conditioner.

[0040] In the present utility model, the air sterilization module performs the first sterilization on the passing air by the ultraviolet rays emitted by the ultraviolet lamp 111. When the ultraviolet rays irradiate the aluminum-based lamp board 113, they are reflected by the aluminum base material on the surface of the lamp board to the surface of the photocatalyst honeycomb mesh plate 202, activating the photocatalyst on the surface of the mesh plate to perform secondary sterilization and disinfection on the air. The ultraviolet lamp beads and the LED lamp beads have a light-emitting angle and will irradiate the aluminum-based lamp board 113 from different angles and then be reflected to the surface of the photocatalyst honeycomb mesh plate 202.

[0041] The utility model utilizes the reflection characteristic of the aluminum-based lamp board 113 itself to reflect the ultraviolet rays emitted by the ultraviolet lamp board in the first sterilization component 1 onto the photocatalyst layer on the surface of the photocatalyst honeycomb mesh board 202 in the second sterilization component 2, thereby activating the photocatalyst. After the air entering the automotive air conditioner is sterilized by the pure ultraviolet rays of the first sterilization component 1, it is further purified by the photocatalyst activated by the ultraviolet rays, further improving the air quality. The second busbar PCB board 114 also has certain reflection characteristics, but the effect is not as good as that of the aluminum-based lamp board 113.

[0042] In this embodiment, the connecting wire 102 is electrically connected to the vehicle-end wiring harness, so that the air sterilization module is controlled by the vehicle control circuit. In this embodiment, the connecting wire 102 is assembled with the socket on the lamp board assembly 110 through a plug.

[0043] In this embodiment, there is a U-shaped rubber plug on the connecting wire 102, which is assembled with the corresponding U-shaped cavity on the bottom case. The second shock-absorbing foam 3 has an avoidance structure for the connecting wire 102 to pass through.

[0044] The utility model provides an air sterilization module for an automotive air conditioner, which is applicable to an automotive air conditioning system. The utility model reflects the ultraviolet rays onto the photocatalyst honeycomb mesh board 202 through the reflection characteristic of the aluminum-based lamp board 113 to activate the photocatalyst, thereby achieving the purpose of combining ultraviolet rays and photocatalyst to disinfect the air.
