They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0027] like Figures 1-8 As shown, the utility model is a constant temperature heater for genetic testing, comprising a thermal insulation and heating box 1, a support plate 2 and a placement plate 3. A partition is provided in the thermal insulation and heating box 1, which divides the thermal insulation and heating box 1 into a water storage chamber 6 and a driving chamber 7 from top to bottom. A heating tube 8 for heating the water source in the water storage chamber 6 and a temperature sensor 9 for monitoring the water temperature in the water storage chamber 6 are provided on the thermal insulation and heating box 1. A supporting mechanism 4 and a stirring assembly 5 are provided in the water storage chamber 6. The supporting plate 2 is provided on the supporting mechanism 4, and the height of the supporting plate 2 can be adjusted by the supporting mechanism 4. A through groove 11 is provided on the supporting plate 2, and the placement plate 3 is provided at the opening of the water storage chamber 6, and a placement hole 12 is provided on the placement plate 3; a positioning groove 23 is provided at the opening of the water storage chamber 6, and the placement plate 3 is placed in the positioning groove 23; a handle 24 is provided on the placement plate 3; a drain pipe 25 is provided on the thermal insulation and heating box 1, and the drain pipe 25 is connected to the water storage chamber 6, and a valve 26 is provided on the drain pipe 25.

[0028] The support mechanism 4 includes a support unit, a driven pulley 15, a driving pulley 16, a transmission belt 17 and a first motor 18. The support unit includes a screw 13 and a sleeve 14. The screw 13 is rotatably arranged on the partition, and the sleeve 14 is sleeved on the screw 13 through a threaded sleeve. A guide frame 10 is provided in the water storage chamber 6. The sleeve 14 is engaged and slides through the guide frame 10. The driven pulley 15 is sleeved on the screw 13 and is located in the driving chamber 7. The first motor 18 is provided at the bottom of the thermal insulation heating box 1. The output shaft of the first motor 18 rotates and extends into the driving chamber 7. The driving pulley 16 is sleeved on the output shaft of the first motor 18, and the transmission belt 17 is sleeved on the driven pulley 15 and the driving pulley 16; a magnet 22 is provided on the top of the sleeve 14, and the support plate 2 is adsorbed on the magnet 22; the support unit is provided with four groups.

[0029] The stirring assembly 5 includes a stirring shaft 19, a stirring blade 20 and a second motor 21. The second motor 21 is arranged at the bottom of the thermal insulation and heating box 1. The stirring shaft 19 is arranged on the output shaft of the second motor 21 and rotates through the bottom wall and partition of the thermal insulation and heating box 1 to extend into the water storage chamber 6. The stirring blade 20 is arranged on the stirring shaft 19.

[0030] During specific use, the support plate 2 is placed on the sleeve 14, and the support plate 2 is adsorbed by the magnet 22 to improve the stability of the support plate 2, and then water is added to the water storage chamber 6, and the placement plate 3 is placed in the positioning groove 23, and then the sample test tube is inserted into the water through the placement hole 12, and the bottom of the test tube is supported by the support plate 2. The water in the water storage chamber 6 can be heated by the heating tube 8, so that the sample test tube is heated at a constant temperature. During the constant temperature heating process, the second motor 21 is started, and the stirring shaft 19 is driven to rotate by the second motor 21. The stirring shaft 19 drives the stirring blade 20 to rotate to stir the water, accelerate the heat convection inside the water body, make the heat spread and distribute faster in the water body, break the temperature stratification in the water body, mix the water in the high temperature area with the water in the low temperature area, so that the water temperature in the water storage chamber 6 is more uniform, and the water temperature in the water storage chamber 6 is monitored by the temperature sensor 9.

[0031] The height of the support plate 2 can also be adjusted according to the actual height of the sample test tube. When adjusting, it is only necessary to start the first motor 18 so that the first motor 18 drives the active pulley 16 to rotate, and the active pulley 16 drives the driven pulley 15 to rotate through the transmission belt 17, and the driven pulley 15 drives the screw rod 13 to rotate, and the screw rod 13 drives the sleeve 14 to slide up and down in the guide frame 10, and the sleeve 14 drives the support plate 2 to rise and fall, thereby realizing the adjustment of the height of the support plate 2, thereby better supporting sample test tubes of different heights, and improving the practicality of the heater.

[0032] After use, open the valve 26 and drain the water in the water storage chamber 6 through the drain pipe 25. When it is necessary to clean the inside of the thermal insulation and heating box 1, just remove the placement plate 3 from the positioning groove 23 and remove the support plate 2 from the sleeve 14 before cleaning the inside of the thermal insulation and heating box 1.

[0033] To sum up, this solution is provided with a support mechanism 4, which facilitates the adjustment of the height of the support plate 2 through the support mechanism 4. By adjusting the height of the support plate 2, it is convenient to support test tubes of different heights, thereby improving the practicality of the heater; this solution is provided with a stirring component 5, which facilitates the stirring of water through the stirring component 5, thereby reducing the temperature difference between the upper and lower water layers in the water storage chamber 6, and making the water temperature in the water storage chamber 6 more uniform.
