Description

Technical Field

[0001] The utility model relates to a UV-LED lamp ultraviolet intensity detection tool, belonging to the technical field of detection of drinking water sterilizers. Background Art

[0002] The UVC lamp beads of the ultraviolet light emitting diode (UVC-LED) drinking water sterilizer emit ultraviolet rays in the range of 260 to 280 nanometers, which have strong bactericidal ability. When ultraviolet rays irradiate microorganisms (such as bacteria, viruses, etc.), they can destroy the DNA and RNA structure of microorganisms, causing them to lose their ability to reproduce, thereby achieving the purpose of sterilization and disinfection.

[0003] At present, the national standards for ultraviolet disinfection equipment include GB / T 19837 "Ultraviolet disinfection equipment for urban water supply and drainage" and GB 19258 "Ultraviolet germicidal lamps", and the industry standard is QB / T 4827 "Ultraviolet sterilization units for drinking water treatment devices for household and similar purposes". However, these product standards are mainly aimed at large-scale ultraviolet sterilizers with mercury lamps. The existing testing equipment is not suitable for testing the ultraviolet intensity of UV-LED lamps, especially when UV-LED lamps are used in household water purifiers. Since household water purifiers are water-related products, all water-related accessories should have corresponding inspection and testing reports in accordance with relevant regulations. There is currently no standard test method for the ultraviolet intensity of UV-LED lamps. Therefore, it is necessary to design a set of test tools suitable for UV-LED ultraviolet intensity to ensure the accuracy of the test data. Utility Model Content

[0004] The utility model provides a UV-LED lamp ultraviolet intensity detection tool, which is suitable for detecting the ultraviolet intensity of the UV-LED lamp and has a simple structure and wide adaptability.

[0005] In order to solve the above technical problems, the technical solutions adopted by the present utility model are as follows:

[0006] A UV-LED lamp ultraviolet intensity detection tool, comprising an auxiliary radiator, a rear cover, a main sleeve, an auxiliary sleeve, a front cover, an ultraviolet intensity detector and an ultraviolet intensity detection probe;

[0007] The movable cover of the rear cover is arranged on the top of the main sleeve, and the top edge of the main sleeve is provided with a C-shaped wiring hole; a light board connection area is provided on the inner side of the rear cover; the auxiliary radiator is installed on the outer side of the rear cover; one end of the auxiliary sleeve is movably connected to the bottom of the main sleeve, and the other end is movably connected to the front cover, or the bottom of the main sleeve is movably connected to the front cover; the ultraviolet intensity detection probe is installed on the inner side of the front cover, and the ultraviolet intensity detector is located on the outer side of the front cover and is connected to the ultraviolet intensity detection probe through a line.

[0008] Usually, the test distance from the lamp bead to the UV intensity detection probe is required to be about 3cm. Due to the different thicknesses of UV-LED light boards, for thicker UV-LED light boards, an auxiliary sleeve is required to extend the distance. For thinner UV-LED light boards, no auxiliary sleeve is required.

[0009] The above tooling can be used for UV-LED lamp ultraviolet intensity testing.

[0010] In this application, "active connection" refers to a detachable connection.

[0011] In the present application, the inner side of the rear cover and the inner side of the front cover both point to one side inside the main sleeve, and the side facing away from the main sleeve is the outer side.

[0012] The line between the ultraviolet intensity detector and the ultraviolet intensity detection probe passes through the side wall of the front cover and is sealed and fitted with the side wall of the front cover.

[0013] During the test, connect the UV-LED light board to the light board connection area on the back cover, and set the back cover on the top of the main sleeve. At this time, the UV-LED light board lamp beads are downward (that is, pointing to the ultraviolet intensity detection probe), and the power cord on the UV-LED light board passes through the C-type cable hole. After determining the test distance of the UV-LED light board, adjust the distance from the light board to the ultraviolet intensity detection probe through the auxiliary sleeve. After ensuring that there is no light overflow from the sleeve, turn on the ultraviolet intensity detector, turn on the power of the UV-LED light board, and detect the ultraviolet intensity through the ultraviolet intensity detection probe. After the test, turn off the power of the UV-LED light board and the ultraviolet intensity detector, and remove the UV-LED light board.

[0014] When the UV-LED lamp is turned on, it will generate a lot of heat. The auxiliary radiator can help dissipate heat and prevent the tooling from overheating.

[0015] The above-mentioned UV intensity detector and UV intensity detection probe can be directly purchased as existing products. The two are matching products. This application has no special improvements on the structure and signal transmission method of the UV intensity detector and UV intensity detection probe themselves, which will not be repeated here.

[0016] If the auxiliary radiator is an auxiliary radiator with a circuit structure, it is necessary to turn on the power of the auxiliary radiator during the test, and turn off the auxiliary radiator after the test is completed.

[0017] The back of the light board is flat, and the front is the lamp beads.

[0018] The cable hole is set to a C shape, which is convenient for the power cord on the UV-LED lamp board to pass through and can also better ensure the sealing.

[0019] In order to improve the adaptability and accuracy of the device, the main sleeve is a trumpet structure that tapers from top to bottom. In this way, the radiation light of the UV-LED lamp can be completely focused on the UV intensity detection probe, which can be applied to the testing of UV-LED lamps of various sizes.

[0020] In order to improve the accuracy of the test, the materials used for the above-mentioned back cover, main sleeve and front cover are all polytetrafluoroethylene. This can reduce the reflection loss of the UV-LED lamp radiation. And if the UV-LED light board is bonded to the inside of the back cover with double-sided tape during the test, it is easier to remove the glue after the UV-LED light board is removed from the back cover after the test is completed.

[0021] The selection of the above-mentioned polytetrafluoroethylene is mainly based on the consideration of detection accuracy. Of course, the thermal conductivity of polytetrafluoroethylene is poor. This application sets an auxiliary radiator on the back cover, which can alleviate the overheating of the tooling to a certain extent. After practice, it meets the detection requirements.

[0022] As one specific implementation scheme, the thickness of the rear cover is 0.3-0.5 cm; the thickness of the main sleeve and the front cover is 0.8-1.2 cm.

[0023] In order to improve the sealing performance during detection, when an auxiliary sleeve is required, an anti-ultraviolet sealing rubber ring is provided between the rear cover and the main sleeve, and between the auxiliary sleeve and the main sleeve and the front cover. When the auxiliary sleeve is not required, an anti-ultraviolet sealing rubber ring is provided between the rear cover and the main sleeve, and between the main sleeve and the front cover. The anti-ultraviolet sealing rubber ring can be provided on any one of the two interconnected components, and a groove is provided along the periphery of this component, and the anti-ultraviolet sealing rubber ring is installed in the groove and is higher than the groove. The anti-ultraviolet sealing rubber ring is made of anti-ultraviolet silicone and the like. You can directly purchase existing related products, and of course it can also be customized. The anti-ultraviolet sealing rubber ring can be replaced regularly according to actual conditions to ensure sealing performance.

[0024] In order to further improve the sealing performance during detection, an anti-ultraviolet elastic layer is provided along the periphery of the C-type cable hole. This can improve the sealing performance of the detection. The anti-ultraviolet elastic layer is made of anti-ultraviolet silicone and the like.

[0025] In view of the different thicknesses of the original wires of different UV-LED light panels, in order to ensure the sealing and improve the adaptability at the same time, the anti-ultraviolet elastic layer is movably engaged with the C-type cable hole through the grooves set along the outer periphery. The anti-ultraviolet elastic layer has more than two different thicknesses. This can be used for light panel wires with large differences in thickness.

[0026] As one specific implementation solution, the auxiliary heat sink is a fin-type heat sink.

[0027] In order to adapt to the detection of different UV-LED light boards, as one of the specific implementation schemes, the number of auxiliary sleeves is two or more with different heights. In this way, the auxiliary sleeve of appropriate height can be selected according to the thickness of the UV-LED light board to be measured to ensure the required detection height.

[0028] In order to adapt to the detection of different UV-LED light panels, as another specific implementation scheme, the auxiliary sleeve is a telescopic structure. The telescopic structure here can directly adopt the existing telescopic structure, that is, the auxiliary sleeve is a height-adjustable structure, such as a telescopic structure similar to a selfie stick or a telescopic teaching pen; for example, the existing folding barrel side wall structure can be adopted, and the two ends adopt a hard structure to facilitate the connection with the main sleeve and the front cover, and the middle adopts a folding structure. The two ends are stretched outward to extend, and the two ends are squeezed to shorten. When the external force is removed, the existing shape and length can be maintained, and it can withstand a certain weight.

[0029] The auxiliary sleeve is movably plug-in or threadedly connected to the main sleeve and the front cover.

[0030] In order to improve the accuracy of detection, during detection, the back of the light board needs to be close to the rear cover to reduce or avoid the light being blocked by the back of the light board when it is reflected in the tooling.

[0031] In order to simplify the structure and facilitate operation, as one of the specific implementation solutions, the UV-LED light board is bonded to the light board connection area on the inside of the back cover with double-sided adhesive. The test is usually completed within a dozen to dozens of seconds. After the test is completed, the residual adhesive on the back cover and UV-LED light board is removed.

[0032] In order to simplify the operation, as another implementation scheme, more than two circles of annular card pockets are provided in the light board connection area on the inner side of the back cover. The outer periphery of the annular card pocket is connected to the inner wall of the back cover. The inner periphery of the annular card pocket is an elastic closing structure. The periphery of the UV-LED light board is installed in one of the annular card pockets. When testing, the edge of the UV-LED light board can be installed in a suitable annular card pocket. In this way, there is no need to remove the glue.

[0033] The technologies not mentioned in this utility model are all referred to the prior art.

[0034] The utility model UV-LED lamp ultraviolet intensity detection tooling has the following beneficial effects:

[0035] 1) Suitable for detecting the ultraviolet intensity of UV-LED lamps, with simple structure and wide adaptability.

[0036] 2) The present application installs an auxiliary radiator on the rear cover to prevent the auxiliary tooling from overheating.

[0037] 3) A C-shaped cable hole is provided on the top edge of the main sleeve of the present application, so that the back cover and the sleeve can be completely sealed to reduce the spillage of radiation light.

[0038] 4) This application can adjust the distance from the UV-LED light board to the ultraviolet intensity detection probe according to actual conditions through the auxiliary sleeve to ensure the accuracy of the test data.

[0039] 5) Existing UV-LED lamp panels vary in size and irradiation angles. This application designs the main sleeve into a cone shape so that the radiation light of the UV-LED lamp is completely focused on the ultraviolet intensity detection probe, thereby improving the accuracy of the detection and being applicable to the testing of UV-LED lamps of various sizes.

[0040] 6) The material of the main sleeve and the back cover is preferably polytetrafluoroethylene (PTFE), which can reduce the reflection loss of the UV-LED lamp radiation.

[0041] 7) An anti-ultraviolet sealing rubber ring is provided between the back cover and the main sleeve to reduce the loss of UV-LED lamp radiation and improve accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
