DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Embodiment 1

[0033] See also Figure 1-7 As shown, a dry cell resuscitation instrument with an infrared temperature control system comprises a base 2 and an upper shell 1, wherein the upper shell 1 is mounted on the base 2 to form a main body of the resuscitation instrument;

[0034] The main body of the resuscitation device is provided with a heating module, a temperature sensing module 12, a control module 13, a display module and a heat dissipation module;

[0035] The sample holding chamber 10 is a two-piece clamping block, and arc-shaped grooves are formed on the surfaces of the two sides close to each other;

[0036] A guide tube 4, wherein the guide tube 4 is arranged on the surface of the upper shell 1, and the guide tube 4 is concentric with the sample holding cavity 10;

[0037] The heating module and the temperature sensing module 12 are both disposed on the sample holding chamber 10 and are used to heat the sample and monitor the sample temperature in real time;

[0038] The control module 13 is fixedly mounted on the base 2, and a switch is provided on the surface of the control module 13. The heating module, the temperature sensing module 12 and the heat dissipation module are all connected to the control module 13 through wires. The heating module is a silicone electric heating sheet 11, which is used to evenly heat the sample. The temperature sensing module 12 is an infrared temperature sensor. The display module is a display screen 3, which is used to display temperature data and resuscitation progress in real time.

[0039] During operation, the sample is placed in the sample holding chamber 10 through the guide tube 4, and then the switch of the control module 13 is used to control the heating of the electric heater to achieve rapid cell recovery. Because there are multiple infrared temperature sensors distributed at different positions of the sample holding chamber 10, the temperature data can be monitored in real time through the infrared temperature sensor. The control module 13 automatically adjusts the heating power of the silicone electric heater 11 using the PID control algorithm according to the data fed back by the infrared temperature sensor to keep the temperature in the sample holding chamber 10 within the set range. The silicone electric heater 11 has the characteristics of rapid heating and uniform heating, and fits more closely with the sample cryopreservation tube, which is beneficial to the recovery of cells. Uniform recovery, and finally the temperature data and recovery process are displayed in real time through the display screen 3. At the same time, an alarm module is also arranged inside the recovery instrument body. When the process is completed, an alarm can be automatically sounded to prompt the operator to take out the sample in time. Finally, the excess heat inside the recovery instrument body is quickly discharged through the heat dissipation module, which delays the aging speed of internal components and increases the service life, thus avoiding the pollution risk of traditional water bath heating and ensuring the cleanliness of cell samples. In addition, the multi-point infrared temperature sensor and PID control algorithm can also achieve high-precision temperature control to ensure the stability of the cell recovery process. The equipment is user-friendly in design, simple in operation, and user-friendly in interface, making it easy for users to use.

[0040] The heat dissipation module includes a heat dissipation fan 5, a heat dissipation hole is provided on the surface of the base 2, an air inlet hole 101 is provided on the surface of the upper shell 1, and a filter screen 6 is provided in the heat dissipation hole and the air inlet hole 101, the heat dissipation fan 5 is provided on one side of the air inlet hole 101, a fixing ring 9 is fixedly connected to the surface of the air inlet hole 101, the filter screen 6 is connected to the fixing ring 9 through a fixing structure, a transmission shaft 15 is connected to the surface of the heat dissipation fan 5 through a centrifugal structure, an end of the transmission shaft 15 away from the heat dissipation fan 5 passes through the filter screen 6 for rotational connection, and a top cover 8 is connected to the surface of the part passing through the filter screen 6 through a thread, a lever 7 is fixedly connected to the surface of the top cover 8, and the lever 7 is arc-shaped and has a chamfered surface;

[0041] During operation, after the resuscitation work is completed, the control module 13 controls the cooling fan 5 to start, so that the external air enters the resuscitation instrument body through the air inlet 101, and the excess internal heat is discharged through the cooling holes. When the cooling fan 5 shaft rotates, it will drive the connecting shaft 16 to rotate, and the connecting shaft 16 drives the scraper rod to scrape the surface of the filter 6 to scrape the dust and impurities on the surface of the filter 6. Because the surface of the resuscitation instrument body is provided with cooling holes and air inlet 101, the gas enters the resuscitation instrument body through the air inlet 101 under the negative pressure generated by the cooling fan 5, and is discharged through the cooling holes. Therefore, impurities will be adsorbed in the holes of the filter 6 on the surface of the air inlet 101, causing blockage, which can be cleaned by the scraper rod, effectively avoiding the blockage of the filter 6. At the same time, the scraper rod can be removed by the threaded top cover 8, and the filter 6 can be disassembled by the structure, so that the filter 6 can be replaced and cleaned regularly. The cleaning effect of the scraper rod can be improved by chamfering the surface of the scraper rod. The top cover 8 is installed with a thread, and the rotation direction of the thread is opposite to the rotation direction of the shaft of the cooling fan 5, so that the top shaft can be tightened as it rotates to avoid looseness.

[0042] The centrifugal structure includes a gravity block 17, which is slidably connected to the surface of the rotating shaft of the cooling fan 5 through a spring, and the other end of the gravity block 17 is fixedly connected to a connecting shaft 16, and the end of the connecting shaft 16 away from the gravity block 17 passes through the rotating shaft of the cooling fan 5 for sliding connection, and the end is fixedly connected to an insert block 14, and a slot is provided on the surface of the transmission shaft 15 relative to the position of the insert block 14, and two gravity blocks 17 are provided;

[0043] During operation, through the centrifugal structure, at the initial start-up of the cooling fan 5, when the speed is slow, the spring drives the gravity block 17, and the gravity block 17 drives the plug block 14 to be stuck in the slot. When the speed of the cooling motor gradually increases, the centrifugal force generated by the rotating shaft of the cooling fan 5 will drive the gravity block 17 to slide away from each other. At the same time, the gravity block 17 drives the plug block 14 to disengage from the slot, so that the connection between the transmission shaft 15 and the cooling fan 5 is disconnected. At this time, the scraper rod will not rotate. Through the design of the centrifugal structure, the frequency of rotation of the scraper rod can be reduced, so that the scraper rod only cleans the filter 6 when the cooling fan 5 starts and stops, which can effectively reduce the wear rate of the scraper rod and thus increase its service life.

[0044] The fixing mechanism includes a guide block 20, a baffle 23 is fixedly connected to the surface of the guide block 20, an elastic sheet 22 is fixedly connected to the end of the baffle 23 away from the guide block 20, a clamping block 21 is fixedly connected to the surface of the elastic sheet 22, a notch 18 is provided on the surface of the fixing ring 9, a fixing groove 19 is provided on the side wall of the notch 18, a clamping groove is provided on the side wall of the fixing groove 19 relative to the position of the clamping block 21, a slider 24 is slidably connected to the surface of the guide block 20 through a spring, and a rotating wheel is rotatably connected to the surface of the slider 24;

[0045] During operation, the filter screen 6 is moved toward the direction close to the fixing ring 9, and at the same time, the guide block 20 is driven to be stuck in the slot 18, and then the filter screen 6 is rotated, so that the guide block 20 drives the spring piece 22, and the spring piece 22 drives the card block 21 to be stuck in the card slot, and the filter screen 6 is restricted by the card block 21 to prevent rotation, and the filter screen 6 is fixed by the baffle 23, so that the filter screen 6 can be easily disassembled, replaced and cleaned. The rotating wheel on the surface of the slider 24 can reduce the friction between the guide block 20 and the slot 18. At the same time, the spring can drive the slider 24 to pop out when the filter screen 6 is disassembled, so as to facilitate the disassembly of the filter screen 6.
