Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, the aging test apparatus includes a case 1, a cover plate 2, and an ultraviolet lamp 3 disposed in the case 1. The box body 1 is enclosed by plates to form an inner cavity 11, the inner cavity 11 is provided with an opening 111, the cover plate 2 is rotatably arranged on the upper edge of the opening 111 through the hinge 7, the cover plate 2 is matched with the opening 111 in shape, and the opening 111 can be completely covered after the cover plate 2 is rotated, so that the inner cavity 11 is closed. When the cover plate 2 is opened, the opening 111 can be exposed to take out or put in the sample to be tested, and the sample to be tested is placed on the bottom plane of the inner cavity 11. In this case, the opening 111 is located on the side of the cavity 11 to facilitate sample taking, and the opening 111 occupies the entire side of the case 1 to enable a larger operating window. Although the opening 111 of this example is provided at one side of the cavity 11, it is also possible to provide the opening 111 at the other side of the cavity 11 and provide the cover plate 2 at the opening 111.

The ultraviolet lamp tube 3 is positioned at the top of the inner cavity 11 and extends along the length direction of the inner cavity 11, and the ultraviolet lamp tube 3 emits ultraviolet rays to irradiate the surface of a detected product. In order to reduce the loss of light, a lampshade 5 is arranged above the ultraviolet lamp tube 3; in order to promote the ultraviolet rays emitted by the ultraviolet lamp tube 3 to irradiate downwards, the lower surface of the lampshade 5 is a reflecting surface.

A plurality of reflecting lenses 4 are attached to the inner wall of the box body 1 corresponding to the two ends of the inner cavity 11 in the length direction. Clean reflecting lenses 4 are pasted on the left and right box walls and the back box wall of the box body 1 by VHB adhesive tapes. And the cover plate 2 is attached with the reflection lenses 4 at the positions corresponding to the two ends of the inner cavity 11 in the length direction. The surface of the reflecting lens 4 is smooth or frosted, and if the surface is smooth, the intensity of reflected light is higher; or frosted, the uniformity of the reflected light is higher. Thus, the products placed in the cavity 11 at both ends in the longitudinal direction of the cavity 11 can receive more ultraviolet rays reflected from the mirror plate 4, thereby having sufficient irradiation intensity.

Comparing fig. 2 and fig. 3, in fig. 2, the irradiation intensity at both ends of the cavity 11 fails to reach 0.4W/m without adding the reflection lens 4²The requirements of (1); in fig. 3, after the reflector 4 is added, the irradiation intensity of the whole space in the cavity 11 meets the requirement.

As shown in FIG. 1, in order to prevent the safety hazard caused by overheating inside the box 1, a plurality of heat dissipation holes 12 are further formed in the side wall of the box 1, and the heat dissipation holes 12 are located above the rear side wall of the box 1.

In order to make the device more compact, an electric cabinet 6 is further integrated on the side wall of the box body 1, and the electric cabinet 6 is used for supplying power to the ultraviolet lamp tube 3.

In summary, in this embodiment, the inner wall of the box 1 is provided with the plurality of reflective lenses 4, so that the products to be tested at the two ends of the inner cavity 11 in the length direction can be irradiated by ultraviolet rays with sufficient intensity, thereby ensuring the accuracy of the test result.
