Description

Technical Field

[0001] This utility model relates to the field of illuminance technology, and in particular to an ultraviolet illuminance meter that displays the sun protection UPF rating. Background Technology

[0002] Currently, the UPF (ultraviolet protection factor) testing of sun protection products (such as clothing, parasols, etc.) mainly relies on the laboratory environment, using artificial ultraviolet light sources (such as xenon lamps) to simulate solar radiation, and measuring according to standard testing procedures (such as GB / T18830).

[0003] However, this method has significant limitations: First, the testing is costly, requiring sophisticated instruments and constant laboratory temperature and humidity conditions; second, the scenarios are limited, making it impossible to evaluate the actual sun protection performance of products outdoors in real time, especially difficult to simulate dynamic usage environments (such as exercise, sweating, etc.); in addition, the spectral distribution of artificial light sources differs from that of natural sunlight, which may lead to distortion of the UVA / UVB ratio and affect the authenticity of the test results.

[0004] Therefore, this application proposes an ultraviolet radiometer that displays the sun protection UPF rating to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an ultraviolet radiometer that displays the sun protection UPF rating, thus solving the technical problems mentioned in the background art.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution: an ultraviolet radiation meter displaying the UPF rating of sun protection, including a detection frame 1, a handle 20 fixedly connected to the front end of the detection frame 1, an information processing module 22 arranged inside the detection frame 1, two detection slots 5 opened at the upper end of the detection frame 1, ultraviolet detection sensors 6 fixedly connected to the lower inner walls of the two detection slots 5, narrow-band filters 7 arranged at the upper ports of the two detection slots 5, fixing mechanisms 3 arranged at both the left and right ends of the detection frame 1, the rear narrow-band filter 7 located between the two fixing mechanisms 3, and a display screen 2 rotatably connected to the rear end of the upper surface of the detection frame 1 via a damping shaft. During detection, the fixing mechanism 3 is used to fix the position of the material to be tested. A dual detection slot 5 structure is adopted, each equipped with a narrow-band filter 7 and an ultraviolet detection sensor 6; one is used to detect the UVA / UVB bands under natural external conditions; the other is covered with the material to be tested and used to detect the UVA / UVB bands after the sun protection material to be tested is placed; the accuracy of UPF detection is ensured by comparing the data of the two in real time.

[0022] The formula for calculating UPF is:

[0023]

[0024] Where α and β are preset weighting coefficients;

[0025] IUVA and IUVB are the UVA / UVB radiation intensities collected in separate wavelengths using narrowband filters;

[0026] TUVA and TUVB represent the transmittance of the test object in the corresponding wavelength band;

[0027] The fixing mechanism 3 includes a traction plate 8, a pressure plate 13 is provided above the traction plate 8, and an adjusting screw 14 is fixedly connected to the rear end of the lower surface of the pressure plate 13. The lower end of the adjusting screw 14 passes through the traction plate 8 and is threadedly connected to an adjusting rotating plate 16. The adjusting screw 14 is slidably connected to the traction plate 8. A compression spring 15 is sleeved on the adjusting screw 14. The upper and lower ends of the compression spring 15 abut against the adjacent side walls of the adjusting rotating plate 16 and the traction plate 8, respectively. Under the action of the tension spring 12, both the left and right ends of the material to be tested are located below the upper surface of the detection main frame 1, thereby ensuring that the material to be tested is always in contact with the upper side wall of the detection main frame 1, and preventing light from entering between the material to be tested and the narrow band filter 7 below, which would affect the detection effect.

[0028] The lower end of the pressure plate 13 is fixedly connected to an anti-slip strip 17, and the upper end of the traction plate 8 is provided with an anti-slip groove 18. The anti-slip strip 17 is adapted to the anti-slip groove 18, and an anti-slip pad 19 is provided on the inner side wall of the anti-slip groove 18. Both the anti-slip strip 17 and the anti-slip pad 19 are made of rubber. The anti-slip rubber material is used to increase the friction between the pressure plate 13 and the traction plate 8, ensuring the stability of the material to be tested during the testing process and avoiding the influence of strong external wind on the equipment testing.

[0029] The fixing mechanism 3 also includes a fixing plate 9, which is fixed on the outer wall of the detection main frame 1. Limiting slide rods 10 are fixedly connected to the front and rear sides of the lower surface of the traction plate 8. The lower end of the limiting slide rod 10 passes through the fixing plate 9 and is fixedly connected to a baffle 11. A tension spring 12 is sleeved on the limiting slide rod 10. The upper and lower ends of the tension spring 12 are fixedly connected to the adjacent side walls of the traction plate 8 and the fixing plate 9, respectively. When in use, the testing personnel place the device outdoors, pull the pressure plate 13 upward, and place the material to be tested between the pressure plate 13 and the traction plate 8 on the left and right sides respectively. The pressure plate 13 and the traction plate 8 are used to press and fix the material to be tested.

[0030] The handle 20 is equipped with operation buttons 21 and a built-in power supply 4. Through the design of the handle 20 and the built-in power supply 4, the device is portable, freeing it from the limitations of the laboratory environment, and UPF testing can be carried out directly in outdoor natural light conditions.

[0031] Working Principle: During use, the testing personnel place the device outdoors and pull upwards on the pressure plate 13. The material to be tested is placed between the pressure plate 13 and the traction plate 8 on both sides, and the pressure plate 13 and traction plate 8 are used to press and fix the material to be tested. Under the action of the tension spring 12, both ends of the material to be tested are located below the upper surface of the main frame 1, thus ensuring that the material to be tested is always in contact with the upper side wall of the main frame 1, preventing light from entering between the material to be tested and the narrow band filter 7 below, which would affect the testing effect. The device adopts a dual detection slot 5 structure, equipped with a narrow band filter 7 and an ultraviolet detection sensor 6 respectively. One slot is used to detect the UVA / UVB band under natural external conditions; the other slot is covered with the material to be tested and is used to detect the UVA / UVB band after the sunscreen material to be tested is placed. The accuracy of UPF detection is ensured by comparing the data of the two slots in real time. The data detected by the two ultraviolet detection sensors 6 is processed by the information processing module 22 and the calculation results are displayed on the display screen 2.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
