[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0028] See also Figures 1 to 5 The present invention provides a resistance meter for detecting sterilization indicators, comprising an outer shell 1, wherein at least three detection tanks 2 for performing sterilization resistance detection are fixedly connected inside the outer shell 1, wherein each detection tank 2 is fixedly connected with a carrying mechanism 3 for loading the sterilization indicator, wherein each detection tank 2 is fixedly connected with a sterilization box mechanism 4 near the carrying mechanism 3, wherein a vacuum pump 5 for changing the internal air pressure of the detection tank 2 is fixedly connected inside the outer shell 1 near the detection tank 2, and wherein a vaporizer 6 for vaporizing the sterilizing substance and passing the sterilizing substance into the sterilization box mechanism 4 is fixedly connected inside the outer shell 1 near the vacuum pump 5.

[0029] set up Figure 1 The middle detection tank 2 is detection tank one, detection tank two, and detection tank three from left to right. At the beginning of the detection, the sterilization indicator is placed in the supporting mechanism 3 in the detection tank one, detection tank two, and detection tank three, respectively. Then, the detection tank one, detection tank two, and detection tank three are evacuated by the vacuum pump 5, and the air pressure in the detection tank one and the detection tank two is made equal, and the air pressure in the detection tank three is higher than the air pressure in the detection tank one and the detection tank two. Then, the sterilization substance (such as hydrogen peroxide, ethylene oxide, etc.) is vaporized by the gasifier 6 and passed into the sterilization box mechanism 4. The sterilization box mechanism 4 is opened to allow the vaporized sterilization substance to enter the detection tank 2, so that the sterilization indicator under different conditions can be detected in one detection test. Multiple parameters are detected in one detection test, which improves the accuracy of the detection and saves the overall detection time.

[0030] See also Figure 4The carrying mechanism 3 includes a fixing frame 7 fixedly connected to the inner wall of the detection tank 2, a carrying box 8 is fixedly connected to the fixing frame 7, a carrying box cover 9 is slidably connected to the carrying box 8, a first mounting groove 10 is opened on the fixing frame 7, a first motor 11 is fixedly connected in the first mounting groove 10, a first rotating shaft 12 is fixedly connected to the output end of the first motor 11, a first rotating shaft 12 is fixedly connected to one end extending outside the fixing frame 7, a first driving gear 13 is fixedly connected to a first fixing seat 14 at a position close to the first driving gear 13 on the fixing frame 7, a first threaded rod 15 is rotatably connected through the first fixing seat 14, a first threaded rod 15 is fixedly connected to one end close to the first driving gear 13 of the first threaded rod 15, and the other end of the first threaded rod 15 is threadedly connected to the carrying box cover 9.

[0031] At the beginning of the test, the carrying box cover 9 is in an open state, so that the sterilization indicator can be placed in the carrying box 8. When the vacuum pump 5 is evacuating, the carrying box cover 9 is in an open state, so that the air in the carrying box 8 is synchronously evacuated to ensure the accuracy and safety of the test. When the vacuum is completed, the air pressure in the second test tank and the third test tank is equal to and higher than the air pressure in the first test tank. The first motor 11 is started, the first motor 11 drives the first rotating shaft 12 to rotate, the rotation of the first rotating shaft 12 drives the first driving gear 13 to rotate, the rotation of the first driving gear 13 drives the first passive gear 16 to rotate, and the rotation of the first passive gear 16 drives the The first threaded rod 15 is driven to rotate, and the rotation of the first threaded rod 15 drives the carrying box cover 9 to move, thereby closing the carrying box 8 to prevent the carrying box 8 from contacting the sterilized substance before the sterilized substance is evenly distributed in the detection tank 2, causing inaccurate test data. When the sterilized substance is evenly distributed in the detection box, the first motor 11 is started and reversed. Through the above-mentioned transmission process, the carrying box cover 9 is opened again, so that the sterilization indicator is directly placed in the sterilized substance of the set concentration, avoiding the sterilization indicator from being directly placed in the entire process of the sterilized substance concentration gradually rising to the set concentration, thereby improving the accuracy of the test.

[0032] See also Figure 5The sterilization box mechanism 4 includes a sterilization box body 17 fixedly connected to the inside of the detection tank 2, a sterilization box cover 18 is slidably connected to the sterilization box body 17, a second mounting groove 19 is opened in the sterilization box body 17, a second motor 20 is fixedly connected in the second mounting groove 19, a second rotating shaft 21 is fixedly connected to the output end of the second motor 20, and one end of the second rotating shaft 21 extending outside the sterilization box body 17 is fixedly connected to a second driving gear 22, a second fixing seat 23 is fixedly connected to the position of the sterilization box body 17 near the second driving gear 22, a second threaded rod 24 is rotatably connected to the second fixing seat 23, a second threaded rod 24 is fixedly connected to one end of the second threaded rod 24 near the second driving gear 22, and the other end of the second threaded rod 24 is threadedly connected to the sterilization box cover 18.

[0033] See also Figure 2 Two adjacent sterilization boxes 17 are connected via a first pipe 26 , and a first solenoid valve 27 for controlling the communication of the first pipe 26 is mounted on the first pipe 26 .

[0034] See also Figure 2 One of the sterilization boxes 17 is connected to the gasifier 6 via a second pipe 28 , and the second pipe 28 is equipped with a second solenoid valve 29 for controlling the connection of the second pipe 28 .

[0035] When vacuuming, the sterilization box cover 18 is in an open state. When vacuuming is completed, the second motor 20 is started, the second motor 20 drives the second rotating shaft 21 to rotate, the second rotating shaft 21 drives the second driving gear 22 to rotate, the second driving gear 22 drives the second passive gear 25 to rotate, the second passive gear 25 rotates to drive the second threaded rod 24 to rotate, the second threaded rod 24 rotates to drive the sterilization box cover 18 to move, so as to close the sterilization box 17, and then the sterilization material is introduced into the sterilization box 17 in the second detection tank through the gasifier 6, and enters the sterilization box 17 in the first detection tank and the third detection tank through the first pipeline 26, and then the first solenoid valve 27 is closed, and the second detection tank 17 is closed. The sterilization box 17 in the tank continues to introduce sterilization material, so that there is more sterilization material in the detection tank 2. Finally, the second solenoid valve 29 is closed, the second motor 20 is reversed, and the sterilization box cover 18 is in the open state again. At this time, the air pressure in the detection tank 2 is lower than the air pressure in the sterilization box 17, and the sterilization material can be dispersed in the detection tank 2 more quickly. The sterilization material in the sterilization box 17 is evenly dispersed in the detection tank 2 after a certain period of time. At this time, the concentration of sterilization material in the detection tank 1 and the detection tank 3 is equal and lower than the concentration of sterilization material in the detection tank 2, thereby realizing the detection of sterilization indicators under different conditions in one detection test, improving the accuracy of the detection, and saving the overall detection time.

[0036] See also Figure 5The second driving gear 22 and the second passive gear 25 are bevel gears, and the second driving gear 22 and the second passive gear 25 are meshed with each other, so that the second motor 20 drives the second threaded rod 24 to rotate through the transmission connection between the second driving gear 22 and the second passive gear 25 .

[0037] See also Figure 4 The first driving gear 13 and the first passive gear 16 are bevel gears, and the first driving gear 13 and the first passive gear 16 are meshed with each other, so that the first motor 11 drives the first threaded rod 15 to rotate through the transmission connection between the first driving gear 13 and the first passive gear 16.

[0038] See also Figure 2 The vacuum pump 5 is connected to the detection tank 2 through a third pipe 30, and the third pipe 30 is equipped with a third solenoid valve 31 for controlling the connection of the third pipe 30. When the vacuum pump 5 is evacuating, the first solenoid valve 27 is closed to make the air pressure in the second detection tank and the third detection tank equal, and then the first detection tank is continuously evacuated. When the evacuation is completed, the third solenoid valve 31 is closed to make the three detection tanks 2 in a sealed state.

[0039] See also Figure 2 and Figure 3 Each of the detection tanks 2 is provided with a detection tank cover 32 for opening and closing the detection tank 2. The volume of each of the detection tanks 2 is equal. The detection tanks 2 are provided with a heater (not shown in the figure). The heater can be a heating film coated on the outer wall of the detection tank 2. The detection tank 2 cover is used to seal the detection tank 2. The volume of each detection tank 2 is equal. When equal sterilizing substances enter the sterilization box 17, the concentration of sterilizing substances in each detection tank 2 is finally equal. The heater keeps the sterilizing substances in a gas state for a long time to avoid liquefaction of the sterilizing substances in a short time and reduce the accuracy of the detection test. When it is necessary to detect the temperature conditions, the temperature of the detection tank 2 can be controlled by controlling the heater to complete the corresponding detection test.

[0040] See also Figure 1 A control system 33 is fixedly connected to the outer shell 1 , and the control system 33 is electrically connected to the first solenoid valve 27 , the second solenoid valve 29 , the third solenoid valve 31 , the vacuum pump 5 and the gasifier 6 .

[0041] The detection tank 2 is provided with a sensor (not shown in the figure) for monitoring various data in the detection tank 2 and transmitting the data to the control system 33 for recording.
