Description

Technical Field

[0001] The utility model relates to the technical field of testing, in particular to a disinfection testing device. Background Art

[0002] Currently, the disinfection and sterilization effectiveness of disinfection cabinets is primarily determined based on the E. coli killing test in Appendix BB of GB17988-2008. This test uses positive and negative control groups and is repeated three times to determine whether the disinfection effectiveness of the test point meets the requirements, thereby further determining the overall disinfection effectiveness of the disinfection cabinet. However, this test method has a long testing cycle, typically requiring a week from test preparation, three positive and negative control tests, to completion. Furthermore, during the development of disinfection cabinet projects, the verification of multiple disinfection factors is extremely time-consuming, significantly impacting the development cycle of the disinfection cabinet product. Furthermore, this method has a high technical threshold, requiring a dedicated microbiology laboratory and microbiology testing capabilities to conduct E. coli killing tests.

[0003] To solve the above technical problems, a Chinese invention patent with patent number ZL201610158380.0 (authorization announcement number CN107198786B) discloses a disinfection cabinet and display method for displaying disinfection effects. The disinfection cabinet includes: a cabinet body, a control panel arranged on the cabinet panel, a disinfection factor generating device and a disinfection factor detection unit arranged in the cabinet body, and an intelligent display system. The intelligent display system includes a display module connected to the control panel, and the disinfection factor detection unit is connected to the input end of the control panel. Although the disinfection cabinet can receive the disinfection factor data transmitted by the disinfection factor detection unit through the control panel to obtain the disinfection effect parameter, and control the display module to display the disinfection factor data and disinfection effect parameter in real time, so as to obtain the sterilization effect of studying the intensity and action time of the sterilization factor, and output the sterilization effect correspondence table based on the test results. However, the above disinfection cabinet has the following usage limitations: there is no position requirement between the disinfection factor generating device, the disinfection factor detection unit and the object to be disinfected in the disinfection cabinet, so the disinfection effect parameter obtained by the above method will have a certain deviation. Therefore, further improvements to the existing technology are needed. Utility Model Content

[0024] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 4 As shown, the disinfection testing device in this embodiment includes a test box 1, a disinfection factor generating device and a disinfection factor detecting device.

[0026] The interior of the test box 1 is hollow to form a cavity 10, and the cavity 10 has a test table 2 for placing the object to be sterilized; Figure 2 and Figure 3 As shown, in this embodiment, the test box 1 is a sealed cubic or rectangular box that needs to have good thermal insulation performance. Two spaced-apart guide rails 11 are provided within the test box 1, and a drawer 12 is slidably restrained on the two guide rails 11. Both ends of each guide rail 11 are fixed to the wall of the test box 1, and the test bench 2 is restrained to the underside of the guide rails 11. The operating principle of the drawer 12 can be referred to as the operating process of the drawer, and will not be further described here.

[0027] The disinfection factor generating device in this embodiment includes an ultraviolet emitter 31 provided in the cavity 10. Correspondingly, the disinfection factor detecting device includes an ultraviolet intensity sensor 32 provided in the cavity 10. The ultraviolet intensity sensor 32 is used to detect the ultraviolet intensity on the upper surface of the test bench 2. The ultraviolet emitter 31 is provided on the cavity wall of the cavity 10 ( Figure 3 The ultraviolet light emitter 31 is arranged on the top wall of the cavity 10), the test table 2 is arranged in the center of the cavity 10 and maintains a certain distance from the bottom wall of the cavity 10, the ultraviolet intensity sensor 32 is arranged below the object to be sterilized, and the ultraviolet light emitter 31, the object to be sterilized and the ultraviolet intensity sensor 32 are coaxially arranged. The ultraviolet light emitter 31 is configured so that the ultraviolet light emitted by the ultraviolet light emitter 31 can directly reach the ultraviolet intensity sensor 32 and the center of the object to be sterilized.

[0028] like Figure 4 As shown, a cavity 21 is provided on the test table 2, and an ultraviolet intensity sensor 32 is disposed within the cavity 21, with the upper surface of the ultraviolet intensity sensor 32 being substantially flush with the upper surface of the test table 2. A glass sheet a, made of quartz glass, is placed on the upper surface of the test table 2 for the object to be sterilized, and the object to be sterilized is a contaminated glass slide. This allows the ultraviolet light emitted by the ultraviolet emitter 31 to directly strike the ultraviolet intensity sensor 32 and the center of the object to be sterilized.

[0029] The disinfection factor generating device further includes at least one of a temperature control module, a humidity control module, and an ozone generator 61. The disinfection factor detecting device further includes at least one of a temperature sensor 43 for detecting the temperature within the cavity 10, a humidity sensor 53 for detecting the humidity within the cavity 10, and an ozone sensor 62 for detecting the ozone concentration within the cavity 10. Since temperature, humidity, and ozone are all important factors affecting the disinfection effect during the actual disinfection process, the disinfection factor generating device in this embodiment further includes a temperature control module, a humidity control module, and an ozone generator 61. Correspondingly, the disinfection factor detecting device further includes a temperature sensor 43, a humidity sensor 53, and an ozone sensor 62.

[0030] The temperature control module includes a heating module 41 and a cooling module 42 that is arranged diagonally or symmetrically with the heating module 41. Through the cooperation between the heating module 41, the cooling module 42 and the temperature sensor 43, the temperature inside the cavity can be accurately controlled to reach the set temperature. The humidity control module includes a dehumidification module 51 and a humidification module 52 that is arranged diagonally or symmetrically with the dehumidification module 51. Similarly, through the cooperation between the dehumidification module 51, the humidification module 52 and the humidity sensor 53, the humidity inside the cavity can be accurately controlled to reach the set humidity. And through the cooperation between the ozone generator 61 and the ozone sensor 62, the ozone inside the cavity can be accurately controlled to reach the set ozone. Figure 2As shown, the heating module 41 and the cooling module 42 in this embodiment are arranged at two diagonal positions of the bottom wall of the test box 1, and the dehumidification module 51 and the humidification module 52 are symmetrically arranged on two opposite sides of the bottom wall of the test box 1; in addition, the ozone generator 61 and the ozone sensor 62 are arranged at the other two diagonal positions of the bottom wall of the test box 1. In this way, the temperature, humidity and ozone in the test box 1 are made more uniform through symmetrical or diagonal arrangements, and the detection values of the temperature, humidity and ozone in the test box 1 are made more accurate.

[0031] The guide rail 11 is also provided with a bracket 7 for installing the temperature sensor 43 and the humidity sensor 53. The temperature sensor 43 and the humidity sensor 53 are arranged on the periphery of the ultraviolet intensity sensor 32, and the detection ends of the temperature sensor 43 and the humidity sensor 53 are arranged in contact with or adjacent to the surface of the glass sheet a.

[0032] The test box 1 is also provided with a circulation fan 8 and a fresh air blower 9. Figure 2 As shown, in this embodiment, there are two circulating fans 8, which are respectively arranged on two opposite side walls of the test box 1. The circulating fans 8 continuously stir the air inside the cavity 10, so that the temperature, humidity and ozone concentration in the internal space of the cavity 10 are kept uniform, further improving the detection accuracy. In addition, a small hole (not shown in the figure) is opened on the test box 1 to connect the inside and outside of the cavity, so that the atmosphere inside and outside the cavity is connected, ensuring that the air pressure in the cavity is one atmosphere.

[0033] In addition, Figure 1 As shown, a control panel b is provided on the upper surface of the test box 1, and the control panel b has a built-in controller. The above-mentioned ultraviolet emitter 31, ultraviolet intensity sensor 32, heating module 41, cooling module 42, temperature sensor 43, dehumidification module 51, humidification module 52, humidity sensor 53, circulation fan 8 and fresh air fan 9 are all electrically connected to the controller, so the operation of the above-mentioned components can be controlled by the controller to control the intensity of each factor.

[0034] In this embodiment, the intensity and action time of a single disinfection factor (one of ultraviolet rays, temperature, humidity, and ozone) or a combined disinfection factor (at least two of ultraviolet rays, temperature, humidity, and ozone) can be studied through an ultraviolet emitter, a temperature control module, a humidity control module, and an ozone generator. The disinfected stained slides are taken out for microbial testing to obtain the disinfection effect, thereby confirming the relationship table corresponding to the single and combined disinfection factors and the disinfection effect. Therefore, it is possible to quickly determine whether the disinfection effect of the entire disinfection equipment can meet expectations based on the relationship table, which can greatly shorten the development cycle of disinfection equipment (such as disinfection cabinets).
