DETAILED DESCRIPTION

[0025] The present invention is described in detail below with reference to the accompanying drawings and embodiments:

[0026] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] like Figure 1-4As shown, a timed temperature-controlled multi-layer sample incubator comprises a bracket 1, a box body 2 is provided on the bracket 1, and a plurality of horizontally arranged support mesh plates 3 are provided in the box body 2. The support mesh plates 3 are used to place glass slides, and the glass slides with samples can be placed on the support mesh plates 3 for incubation. Since the multi-layer support mesh plates 3 are provided, more glass slides can be placed for incubation each time, thereby improving the incubation efficiency. At the same time, in order to improve the applicability of incubating samples placed in test tubes, a plurality of mounting holes 4 for placing test tubes are provided on the support mesh plates 3, and the test tubes can be placed in the mounting holes 4 to facilitate incubation of the samples in the test tubes, thereby improving the applicability of the incubator. The upper surface of the box body 2 is provided with an S-shaped water inlet pipe 5, which is fixed to the upper surface of the box body 2. The box body 2 The lower surface of the box body 2 is provided with an S-shaped water outlet pipe 6 corresponding to the water inlet pipe 5. The water outlet pipe 6 is also fixed to the lower surface of the box body 2, that is, the water inlet pipe 5 and the water outlet pipe 6 are located outside the box body 2 to prevent the water inlet pipe 5 and the water outlet pipe 6 from affecting the temperature inside the box body 2, so that the temperature of the upper and lower parts of the box body 2 is too high compared to the middle part. A plurality of heat conducting pipes 7 are provided in the box body 2. The heat conducting pipes 7 are made of stainless steel pipes. The heat conducting pipes 7 are evenly distributed inside the box body 2. The heat conducting pipes 7 pass through the supporting mesh plate 3. The inside of the box body 2 can be heated by the heat conducting pipes 7, and the temperature inside the box body 2 is uniform, so that the sample is incubated at a suitable temperature. The heat conducting pipes 7 are arranged vertically and do not affect the placement of the glass slides and test tubes on the supporting mesh plate 3. The top of the heat conducting pipe 7 is connected to the box body 2. 2 passes through the upper surface and is connected to the water inlet pipe 5. The bottom end of the heat conducting pipe 7 passes through the lower surface of the box body 2 and is connected to the water outlet pipe 6. Hot water can enter the heat conducting pipe 7 through the water inlet pipe 5 to heat the heat conducting pipe 7, and then be discharged through the water outlet pipe 6. Specifically, one end of the water inlet pipe 5 is a blocking structure, and the other end is connected to a heating tank 8. The blocking structure can prevent the water in the water inlet pipe 5 from flowing out from one end of the water inlet pipe 5 and causing waste. The heating tank 8 is fixed on the bracket 1 and the heating tank 8 is higher than the top of the box body 2. A water filling port 9 is provided on the top of the heating tank 8. A sealing plug 10 is provided at the water filling port 9. Water can be added to the heating tank 8 through the water filling port 9. An electric heating rod 11 is provided in the heating tank 8. The electric heating rod 11 can adopt an existing conventional electric heating rod, which can be used to heat water. The electric heating rod 11 is used to heat the water in the heating tank 8. One end of the water outlet pipe 6 is also in a blocked structure, and the other end is connected to the heating tank 8. The water in the heat pipe 7 can enter the heating tank 8 for circulation heating. The temperature in the box 2 is increased by circulation heating to facilitate sample incubation. A temperature sensor 12 is provided in the box 2. The temperature sensor 12 is used to detect the temperature in the box 2 in real time. The temperature sensor 12 is connected to a controller 13. The controller 13 can be a PLC controller. The controller 13 is connected to the electric heating rod 11. The temperature sensor 12 can transmit the detected temperature information to the controller 13. The controller 13 can control the start and stop of the electric heating rod 11. Specifically, when it is detected that the temperature in the box 2 is close to the upper limit of the set value,The controller 13 controls the electric heating rod 11 to stop heating the water in the heating tank 8. When it detects that the temperature in the box 2 reaches the lower limit of the set value, the controller 13 controls the electric heating rod 11 to start, so as to maintain the temperature in the box 2 within the set range. In addition, the controller 13 can also control the incubation time to facilitate timed incubation. When the incubation time is reached, the controller 13 controls the electric heating rod 11 to stop heating. In addition, because the hot water flows in the heat pipe 7, the generated water vapor will not be emitted into the box 2 and contact the sample, further improving the incubation effect.

[0028] In order to speed up the circulation speed of the water flow and make the temperature of all the heat pipes 7 uniform, a micro water pump 14 is provided on the water inlet pipe 5 near the heating tank 8. The micro water pump 14 is connected to the controller 13, and the start and stop of the micro water pump 14 can be controlled by the controller 13. When the electric heating rod 11 heats the water in the heating tank 8, the controller 13 controls the micro water pump 14 to start, so that the water circulates in the heat pipe 7. When the electric heating rod 11 stops heating the water in the heating tank 8, the controller 13 controls the micro water pump 14 to stop.

[0029] In order to enhance the heat conduction effect of the heat pipe 7 , a plurality of heat conduction fins 15 are provided on the heat pipe 7 along the length direction of the heat pipe 7 . The heat of the heat pipe 7 can be better transferred to the box body 2 through the heat conduction fins 15 .

[0030] A movable door 16 is provided on the front side of the box 1. After opening the movable door 16, the sample can be placed on the supporting mesh plate 3 in the box 2, or taken out from the box 2. An insulation board 17 is provided on the inner wall of the box 2. The insulation board 17 can be used to keep the box 2 warm, prevent heat from dissipating quickly, and save energy.

[0031] The method of using the utility model is as follows:

[0032] When it is necessary to incubate the sample, the movable door on the box body 2 can be opened first, and the paddle or test tube containing the sample can be placed into the supporting mesh plate 3 in the box body 2 or the mounting hole 4 on the supporting mesh plate 3. Due to the provision of multiple supporting mesh plates 3, more samples can be placed in the box body 2, thereby improving the incubation efficiency and incubating the samples in the fragments or test tubes at the same time, which has good applicability. Then, water can be added to the heating tank 8 through the water inlet 9, and the water in the heating tank 8 is filled with the water inlet pipe 5, the water outlet pipe 6 and the heat conduction pipe 7, and then the adding plug is used to seal the adding tank 8. The water inlet 9 of the hot tank 8 is blocked, and then the incubation time and incubation temperature can be set by the controller 13. The incubation temperature can be set to a range value. During incubation, the temperature in the box 2 is maintained within the temperature required for sample incubation. After the setting is completed, the controller 13 controls the electric heating rod 11 in the heating tank 8 and starts the micro water pump 14. Under the action of the micro water pump 14, the water in the heating tank 8 flows into the heat pipe 7 through the water inlet pipe 5, and then flows into the water outlet pipe 6 through the heat pipe 7, and finally flows back to the heating tank 8 through the water outlet pipe 6 for circulation. At the same time, the electric heating rod 11 in the heating tank 8 heats the water in the heating tank 8, so that the circulating water temperature gradually increases. After the water temperature increases, the temperature of the heat pipe 7 increases. The heat pipe 7 transfers the heat to the box body 2 through the heat conducting fins 15, so that the temperature in the box body 2 increases, so that the sample is at a suitable incubation temperature, improving the incubation effect. During incubation, the temperature sensor 12 in the box body 2 detects the temperature in the box body 2 in real time and transmits the detected temperature information to the controller 13. When it is detected that the temperature in the box body 2 is close to the set temperature, the temperature sensor 12 in the box body 2 detects the temperature in the box body 2 in real time and transmits the detected temperature information to the controller 13. When the upper limit of the value is reached, the controller 13 controls the electric heating rod 11 to stop heating the heating tank 8 to prevent the temperature from exceeding the set value. At the same time, the controller 13 controls the micro water pump 14 to stop running. When the temperature in the temperature box 2 reaches the lower limit of the set value, the controller 13 controls the electric heating rod 11 and the micro water pump 14 to start again, and increase the temperature in the box 2, so that the temperature position in the box 2 is within the set range, thereby improving the effect of sample incubation. When the incubation time reaches the set value, the controller 13 controls the electric heating rod 11 and the micro water pump 14 to stop running.

[0033] Since multiple heat pipes 7 are evenly arranged in the box 2, uniform heating and insulation can be performed at all locations in the box 2, preventing temperature differences in the box 2 from affecting sample incubation. In addition, since hot water flows in the heat pipes 7, the generated water vapor will not be emitted into the box 2 and contact the sample, further improving the incubation effect.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
