[0028] Currently, in the laboratory, for the super heat-resistant spore project and the thermophilic aerobic spore project, an induction cooker is required to perform a water bath at 100 °C and boil for 10 minutes or 30 minutes to complete the experiment. However, the test tubes are prone to tipping over during the water bath process, and when heating up, personnel need to check the thermometer at any time and perform manual timing. At the same time, the entire transformation process also requires personnel to monitor in real time, and after the transformation, the test tubes need to be taken out and cooled to room temperature. However, during the taking process, since the water bath reaches 100 °C and is in a high-temperature state, it will cause burns to personnel. Moreover, the long-term boiling of water during the entire transformation process will cause excessive consumption of water in the water tank and requires manual water addition at any time. However, each time the water is changed, it is not only time-consuming and laborious, but also there is a certain risk of burns. Therefore, how to achieve automated operations of automatic temperature control, timing, and water replenishment, and be able to avoid manual transfer of test tubes is a problem that needs to be solved by those in the art currently.
[0029] The technical solutions of this embodiment will be further described below in conjunction with the accompanying drawings and through specific implementation manners.
[0030] As Figures 1 - 3As shown in the figure, this embodiment provides an automatic conversion device, which includes a box body, a moving component 20, a fixing frame 30 and a monitoring component. An isolation layer 10 is arranged inside the box body. The isolation layer 10 divides the inside of the box body into a hot water bath area and a cold water bath area. A number of test tubes 100 can be fixed on the fixing frame 30. The moving component 20 is connected to the fixing frame 30 and enables the fixing frame 30 to switch positions between the hot water bath area and the cold water bath area. The monitoring component includes a water level monitoring system, a temperature monitoring system, a timing system and a voice broadcast system.

[0031] Specifically, in this embodiment, the isolation layer 10 is used in the box body to set up a hot water bath area and a cold water bath area at the same time, which can improve the heating and cooling efficiency of the sample in the test tube 100, and the water in the hot water bath area and the cold water bath area can be isolated by the isolation layer 10 to avoid affecting each other's temperature. Further, the moving component 20 can realize the position switching of the fixing frame 30 between the hot water bath area and the cold water bath area, effectively avoiding the process of manually transporting the test tube 100, thereby reducing potential safety hazards and realizing automated operation. Moreover, the stable placement of the test tube 100 can be ensured by the fixing frame 30 to prevent it from tipping over. Optionally, in this embodiment, the water level monitoring system, the temperature monitoring system, the timing system and the voice broadcast system in the monitoring component can realize automated operations such as automatic temperature control, timing and water replenishment, which not only makes the operation simple, but also greatly reduces the safety risk and saves manpower, thereby improving the overall detection efficiency and the accuracy of the test.
[0032] The specific structure of the automatic conversion device in this embodiment will be described below.
[0033] Such as Figure 1As shown in the figure, in this embodiment, the automatic conversion device includes a box body, a moving component 20, a fixing frame 30, a monitoring component, and a control panel 80. Specifically, the moving component 20 and the fixing frame 30 are both arranged in the box body, and a hot water bath area and a cold water bath area are simultaneously arranged in the box body. The moving component 20 is connected to the fixing frame 30 and can enable the fixing frame 30 to switch positions between the hot water bath area and the cold water bath area. Specifically, a number of test tubes 100 can be fixed on the fixing frame 30, and samples are arranged in the test tubes 100. Thus, the samples can be heated and cooled through the moving component 20 to realize the conversion process. Optionally, the control panel 80 is arranged outside the box body, and the moving component 20 can be driven to start or end the work through the control panel 80 to realize an automatic conversion test. Exemplarily, in this embodiment, the monitoring component includes a water level monitoring system, a temperature monitoring system, a timing system, and a voice broadcast system. The water level monitoring system is arranged on the inner wall of the box body, so as to monitor the water level heights in the hot water bath area and the cold water bath area and perform water injection or drainage accordingly, so as to avoid manual water addition and drainage in the prior art and improve the operation efficiency. Further, the temperature monitoring system and the timing system are both arranged on the fixing frame 30, and the temperature monitoring system can monitor the temperature of the samples in the test tubes 100 to judge whether the target temperature for heating or cooling is reached. Further, the timing system can record the heating or cooling time of the samples, so as to avoid manual real-time monitoring, save manpower, and realize an automatic process. Optionally, the voice broadcast system is arranged on the control panel 80, and the voice broadcast system can be communicatively connected to the temperature monitoring system, so as to give a voice prompt after the samples are heated or cooled to the target temperature, so as to prompt the operator of the current conversion progress and can broadcast in time when the conversion operation ends to facilitate the operator to process in time.
[0034] Combined with Figure 1 and Figure 3 As shown, specifically, in this embodiment, the box body is set as a square structure, and an isolation layer 10 is arranged inside the box body. A protection plate 50 and a heating pipe 60 are arranged in the hot water bath area, a refrigerator 70 is arranged in the cold water bath area, and a shock absorption base 90 is also arranged at the bottom of the box body. Optionally, the isolation layer 10 divides the inside of the box body into a hot water bath area and a cold water bath area, so that two separate water bath tanks are formed inside the box body. The two areas can be thermally insulated through the isolation layer 10 to prevent the temperatures in the two water tanks from being transmitted to each other and affecting the heating or cooling effect of the samples. As Figure 1 shown, in this embodiment, the height of the isolation layer 10 is less than the height of the inner cavity of the box body, and the distance between the upper top surface of the isolation layer 10 and the top surface of the inner cavity of the box body is greater than the height of the fixing frame 30. At the same time, space also needs to be reserved to facilitate the moving component 20 to drive the fixing frame 30 to move above the isolation layer 10, so as to avoid interference when the fixing frame 30 switches positions between the hot water bath area and the cold water bath area.
[0035] Optionally, a heating pipe 60 and a protection plate 50 are provided in the hot water bath area. The protection plate 50 is located above the heating pipe 60 and is used to support the fixing frame 30 to ensure the stable placement of the fixing frame 30 in the hot water bath area. At the same time, it can prevent the samples in the test tube 100 from directly contacting the heating pipe 60, avoiding uneven heating and affecting the conversion process. Further, the heating pipe 60 is arranged at the bottom of the hot water bath area and is used to heat the water in the hot water bath area to increase the water temperature and provide a suitable water bath environment for the conversion test. Correspondingly, a refrigerator 70 is provided in the cold water bath area to cool the water in the cold water bath area to ensure the low-temperature environment of the cold water bath.
[0036] Further, both the hot water bath area and the cold water bath area of the box body are connected to a water pump through water pipes, so that water injection and drainage can be carried out. Specifically, low water level lines and high water level lines are provided on the inner wall of the box body, and liquid level sensors are provided at both the low water level line and the high water level line. Thus, when the water level reaches the low water level line, the water pump will automatically inject water into it. When the water level reaches the high water level line, the water pump will stop injecting water, or drain water when the water level exceeds the high water level line, so as to ensure the controllability of the water level inside the box body. Exemplarily, the liquid level sensor and the water pump are both communicatively connected to the control panel 80, and an intelligent system is provided in the control panel 80, so that automatic operations of water injection and drainage can be realized. The specific communication connection method can be set accordingly according to needs and will not be elaborated here.
[0037] Optionally, a shock-absorbing base 90 is provided at the bottom of the box body. In this embodiment, the shock-absorbing base 90 is set as a special rubber base to improve the stability of the whole device, avoid the influence of desktop vibration on the device, and further increase the environmental comfort during laboratory operations. Further, stainless steel plates 110 are provided on both the inner and outer sides of the wall plate of the box body, and a vacuum layer 120, a density board 130, and a sound-absorbing cotton 140 are sequentially arranged between the two stainless steel plates 110. Specifically, the stainless steel plate 110 serves as the main support of the box body, which can effectively increase the hardness of the box body and prevent the box body from deforming. Further, the vacuum layer 120 can effectively isolate the noise generated during the operation of the device. Optionally, the density board 130 has a relatively thick thickness and can provide isolation and support effects for the vacuum layer 120 and the sound-absorbing cotton 140. Similarly, the sound-absorbing cotton 140 can also effectively prevent the noise of the device from spreading.
[0038] Combined with Figure 1 and Figure 2As shown, in this embodiment, the moving component 20 includes a first telescopic rod 21 and a second telescopic rod 22. Specifically, the first telescopic rod 21 is horizontally arranged on the top of the box body and can drive the second telescopic rod 22 to move horizontally. Further, the second telescopic rod 22 is vertically arranged, and one end of the second telescopic rod 22 is fixedly connected to the first telescopic rod 21, and the other end is connected to the fixing frame 30 and can drive it to move vertically. That is, under the action of the first telescopic rod 21, the fixing frame 30 can move left and right. Under the action of the second telescopic rod 22, the fixing frame 30 can move up and down. Thus, the position switching of the fixing frame 30 between the hot water bath area and the cold water bath area can be realized, and the sample inside the test tube 100 can be heated or cooled to realize the conversion test. Exemplarily, both the first telescopic rod 21 and the second telescopic rod 22 are set as electric type. After being electrically connected to the control panel 80, automatic lifting and left-right movement can be realized.
[0039] As Figure 1 and Figure 2 shown, optionally, the fixing frame 30 is also set as a square frame, and a first fixing plate 31, a second fixing plate 32, fixing clips 33, a temperature probe 34, a temperature sensor 35 and a timer 36 are arranged in the fixing frame 30. Specifically, the first fixing plate 31 and the second fixing plate 32 are arranged in parallel, and a number of first fixing holes are arranged on the first fixing plate 31, and a number of second fixing holes are arranged on the second fixing plate 32. The first fixing holes and the second fixing holes are arranged in one-to-one correspondence. The test tube 100 can sequentially pass through the first fixing holes and the second fixing holes. Thus, the position of the test tube 100 can be guided and limited. At the same time, the arrangement of the first fixing holes and the second fixing holes can also effectively prevent the test tube 100 from tipping over and affecting the conversion test. Optionally, 20 test tubes 100 can be placed in this embodiment, and different placement quantities can be set according to needs in other embodiments.
[0040] Further, fixing clips 33 are arranged on both the first fixing plate 31 and the second fixing plate 32, and the fixing clips 33 can elastically clamp the outside of the test tube 100 to fix the position of the test tube 100 and are applicable to test tubes 100 of different models, thereby expanding the applicable range of the entire device. Exemplarily, each test tube 100 can be locked by two fixing clips 33 at the same time to increase its friction force and further avoid tipping over. Specifically, the fixing clip 33 includes two long rods that cross each other and are connected by an elastic member, and flexible sleeves are sleeved on the ends of the two long rods close to the test tube 100. Thus, while ensuring the stability of the fixed test tube 100, the test tube 100 can be prevented from being clamped and broken. Exemplarily, the elastic member is set as a spring, and the flexible sleeve is set as a silicone soft sleeve.
[0041] Further, a timer 36 is installed outside the top of the fixing rack 30 as a timing system, and a temperature sensor 35 and a temperature probe 34 are installed inside the top of the fixing rack 30 as a temperature monitoring system. The temperature probe 34 can be inserted into the sample, so that the temperature of the sample can be transmitted to the temperature sensor 35. Specifically, the temperature sensor 35 is set to be wireless, and the timer 36 is electrically connected to the temperature sensor 35. Thus, the temperature sensor 35 can sense the temperature of the sample and transmit it to the timer 36 after reaching the target temperature for heating or cooling the sample. In this way, the timer 36 can automatically time, so as to realize intelligent operation and reduce the consumption of manpower in the prior art. Specifically, the timer 36 can record the moment when the target temperature is reached and can also record the heating or cooling time. The corresponding recorded content can be set as needed and will not be elaborated here.
[0042] Exemplarily, a voice broadcast system is set inside the control panel 80, and the voice broadcast system can be communicatively connected to the temperature sensor 35, so as to give a voice prompt after the sample is heated or cooled to the target temperature, to prompt the operator of the current conversion progress, and can give a timely broadcast at the end of the conversion operation to facilitate the operator to process in time. Optionally, an oscillator 40 can also be set below the fixing rack 30, so that the test tubes 100 in the fixing rack 30 can be oscillated according to the requirements of the conversion test, so as to mix the sample. Correspondingly, the control panel 80 can be connected to the computer software by means of Bluetooth or the like, so as to realize the automated operation of driving the moving component 20 and voice broadcast prompt.
[0043] In summary, through the fixing rack 30, a plurality of test tubes 100 of different types can be limited and fixed, and the whole conversion process has both temperature and timing functions, improving the intelligence of detection and reducing the consumption of manpower. Exemplarily, this device is mainly applicable to the pretreatment operation of super heat-resistant and thermophilic aerobic spores. Through the moving component 20, the manual sample transfer can be reduced, the safety factor of the operation is improved, and the fully automatic conversion and cooling operations can be realized by using its intelligent operation, and the water injection and drainage in the box body can be carried out according to needs.
