[0027] Please refer to the attached Figure 4 and attached Figure 6 The outer side of the screw rod 28 is sleeved with a moving block 29 through a thread, and the fan 20 is fixedly installed on one side of the moving block 29. The two sides of the two moving blocks 29 are fixedly connected with a limiting block 30. The inside of the telescopic rod 23 is provided with a spring 35, and the two ends of the spring 35 are connected with the inner rod and the outer rod of the telescopic rod 23 respectively. The inner wall of the telescopic rod 23 is symmetrically provided with a clamping groove 33, and the clamping groove 33 is movably installed with a clamping block 34, and the clamping block 34 is fixedly installed on both sides of the inner rod of the telescopic rod 23.
[0028] Specific, the mobile block 29 and screw 28 through the threaded connection, and the inside of the shell 1 is also provided with a limit slot corresponding to the limit block 30, and the limit block 30 is slidingly installed in the inside of the limit slot, and when the screw 28 rotates and drives the mobile block 29 to move, the mobile block 29 can be limited by the two side limit blocks 30, which can ensure the stability and directionality of the mobile block 29 movement, and when the mobile block 29 moves, it can drive the fan 20 to move inside the shell 1, which can increase the blowing area inside the shell 1, further improve the uniformity of the temperature and humidity distribution inside the shell 1, and the transmission of the worm and the worm gear can ensure the stability of the transmission of the telescopic rod 23, thereby ensuring the stability of the push-pull installation frame 8, preventing the telescopic rod 23 from rotating too fast and causing instability of the push-pull installation frame 8, the spring 35 is connected with the inner rod and outer rod of the telescopic rod 23, and when the connecting rod 15 telescopes and presses the telescopic rod 23 inward, the inner rod of the telescopic rod 23 can press the spring 35 inward, and the spring 35 can push the inner rod outward in the opposite direction, thereby providing a reset thrust to the telescopic connecting rod 15, ensuring the normal fluctuation of the floating rod 36, and simultaneously, due to the limiting of the clamping groove 33 and the clamping block 34, when the outer rod of the telescopic rod 23 is rotated, the inner rod of the telescopic rod 23 can be synchronously rotated, thereby ensuring the normal transmission of the connecting rod 15, and when the telescopic rod 23 telescopes, the clamping block 34 can slide in the clamping groove 33, thereby increasing the directionality of the telescopic rod 23.
[0029] Please refer to the attached Figure 2 and attached Figure 4 The inner wall of the shell 1 is symmetrically provided with a sliding groove 21, and the two sides of the installation frame 8 are fixedly connected with a sliding block 22, and the sliding block 22 is slidingly arranged in the inside of the sliding groove 21.
[0030] Specifically, the sliding block 22 is slidingly installed in the inside of the sliding groove 21, and when the push-pull installation frame 8 is pushed and pulled, the sliding blocks 22 on both sides of the installation frame 8 can slide in the inside of the sliding groove 21, thereby increasing the stability and directionality of the push-pull installation frame 8, and simultaneously, when the sliding block 22 is placed in the inside of the sliding groove 21, the sliding block 22 can also support the installation frame 8, thereby ensuring the stability of the installation frame 8 installed in the shell 1.
[0031] Please refer to the attached Figure 1 and attached Figure 2 One side of the installation frame 8 is fixedly connected with two fixed rods 16, and one end of the fixed rod 16 is fixedly connected with the piston block 6.
[0032] Specifically, the two ends of the fixing rod 16 are connected to the mounting frame 8 and the piston block 6 respectively, and then when the mounting frame 8 is pushed and pulled, the mounting frame 8 can drive the piston block 6 to move inside the extension port 5 through the fixing rod 16 and perform a back-and-forth piston motion. Then, when the piston block 6 moves toward the interior of the shell 1, it can squeeze the air inside the shell 1 inward, and then discharge part of the air inside the shell 1 outward. Synchronously, when the piston block 6 is pushed to move toward the outside of the shell 1, the interior of the shell 1 can be negatively pressurized, and then the external air can be absorbed, thereby realizing the exchange of air inside and outside the shell 1. The advantage of such a setting is that since bacteria will produce a large amount of waste gas during the growth process, these waste gases accumulate excessively and affect the growth of the bacteria themselves, and the waste gas contains a large amount of carbon dioxide. When carbon dioxide accumulates excessively inside the shell 1, it will cause a greenhouse effect in the shell 1, which may cause the temperature inside the shell 1 to continue to rise, affecting the growth environment of the bacteria. By pulling and pulling the piston block 6, the air inside the shell 1 can be exchanged with the air outside, thereby ensuring the growth environment of the bacteria and simultaneously enhancing the linkage and functionality of the device.
[0033] Please see the attached Figure 2 and attached Figure 4 A ventilation hole 13 is formed on the surface of the fixing plate 12 , and a silicone ring 32 is fixedly installed inside the placement hole 10 .
[0034] Specifically, the ventilation holes can ensure that the gentle wind blown out by the fan 20 can circulate inside the housing 1, and a silicone tube is provided inside the placement hole 10. When a test tube container containing a bacterial sample is placed, the silicone tube can contact the surface of the test tube, and simultaneously, through the deformable characteristics of the silicone, its surface fits tightly with the outer wall of the test tube, thereby ensuring the stability of the test tube placed in the placement hole 10. Simultaneously, when the test tube is tilted to both sides to simulate a shaking situation, the silicone ring 32 can be deformed again, thereby preventing the test tube from bending and breaking, thereby ensuring the smooth tilting of the test tube to the left and right.
[0035] Please see the attached Figure 1 and attached Figure 3 The bottom inner wall of the shell 1 is sequentially installed with a thermostat 17, a humidifier 18, a temperature and humidity sensor 19 and a carbon dioxide transmitter. A control panel 2 is installed on one side of the shell 1, and a handle 7 is fixedly installed on the top of the cover 3.
[0036] Specifically, the temperature and humidity inside the shell can be detected by the temperature and humidity sensor 19, the temperature inside the shell 1 can be humidified by the humidifier 18, and the temperature inside the shell 1 can be controlled in real time by the thermostat 17. The temperature and humidity sensor 19, humidifier 18 and thermostat 17 used in the device are relatively mature mechanisms in the prior art, and the functions they achieve are widely used in various fields, so here we will not make too much repetition about their specific principles and structures. The cover plate 3 can be conveniently opened and closed by the handle 7, the temperature and humidity inside the shell can be viewed in real time by the control panel 2, and the humidifier 18, thermostat 17 and motor 31 can be controlled to run, and the temperature and humidity inside the shell 1 can be controlled. By setting a carbon dioxide emitter inside the shell 1, the carbon dioxide concentration inside the shell 1 can be controlled. Since bacteria are cultured, the carbon dioxide emitter of the device should be selected according to the volume of the shell 1, and a carbon dioxide emitter with a concentration of 3%-8% should be selected to provide a suitable living environment for bacteria. Since the survival conditions of bacteria require a suitable carbon dioxide concentration, and using a carbon dioxide emitter to provide a favorable living environment for bacteria is a common technical means in the industry, therefore, here we will not make too much repetition about the specific principles and models of the carbon dioxide emitter.
[0037] The present embodiment provides an automatic device for assisting bacterial sampling and culture of hospital infection. In use, the shell 1 can be placed in a designated position, the cover plate 3 can be opened by the handle 7, and the test tube containing bacterial raw materials can be placed in the placement hole 10 in turn. The test tube placed in the placement hole 10 will be in contact with the silica gel ring 32 on the inner side. The test tube installed in the placement hole 10 is then fastened by the tension of the silica gel ring 32. By regularly opening the motor 31, the motor 31 drives the screw rod 28 to rotate, the screw rod 28 drives the moving block 29 to move on the screw rod 28, the moving block 29 drives the fan 20 to move, the fan 20 is opened, the fan 20 can blow the slow wind to the inside of the shell 1, and then the air flow rate in the shell 1 can be improved, the uniformity of the air temperature and humidity in the shell 1 is ensured, and the growth environment of bacteria is ensured. When the screw rod 28 rotates, the connecting worm 27 can be driven to rotate, the connecting worm 27 drives the second worm wheel 26 to rotate, the second worm wheel 26 drives the double-section worm 25 to rotate, the double-section worm 25 drives the first worm wheel 24 to rotate, the first worm wheel 24 drives the telescopic rod 23 to rotate, the telescopic rod 23 drives the connecting rod 15 to rotate, the connecting rod 15 drives the floating rod 36 on both sides to rotate along the wavy-shaped notch on the surface of the push-pull seat 14, and then the floating rod 36 can be brought up and down, and the connecting rod 15 can be brought in and out. When the connecting rod 15 is brought in and out, the installation frame 8 can be pushed and pulled, the installation frame 8 drives the placement plate 9 on the inside to move left and right in the shell 1, and then the test tube can be moved left and right. When the test tube moves, the test tube can be deflected to the two sides through the limiting of the poking rod 11, and then the effect of shaking the test tube can be simulated. The test tube shaken can increase the contact area of the bacteria and the nutrient medium in the inside, and further ensure the growth environment of the bacteria. When the installation frame 8 moves left and right, the fixed rod 16 can push and pull the piston block 6 to move in the inside of the extension opening 5, the piston block 6 does piston movement in the inside of the extension opening 5. When the piston block 6 is pulled, the air in the shell 1 can be discharged, and when the piston block 6 is pushed, the external air can be sucked in. Therefore, the air exchange in the shell 1 can be realized, the waste gas generated in the bacterial growth process in the shell 1 can be discharged, and fresh air can be introduced, and the growth environment of the bacteria is further increased.
