[0024] The heat conduction component at least includes a spiral tube 4 arranged around the transducer 2 and a spiral heat conduction member 402 arranged in the spiral tube 4, and the inner side of the spiral heat conduction member 402 is in contact with the outer wall of the transducer 2; the cooling component includes a micro water pump 7, a temperature conduction frame 8, and a heat dissipation fin 9 arranged inside the temperature conduction frame 8, a cooling groove 801 is opened inside the temperature conduction frame 8, a plurality of temperature conduction plates 802 are arranged in the cooling groove 801, and the plurality of temperature conduction plates 802 are staggered to form a cooling channel, the cooling channel is filled with coolant, and the interior of the cooling groove 801 is connected to the spiral tube 4 through the micro water pump 7 to form a closed loop Water path, when the transducer 2 generates heat during use, the spiral heat conductor 402 can quickly absorb and conduct its surface heat to the spiral tube 4, and the coolant in the spiral tube 4 can absorb heat by heat transfer. By turning on the water pump, the cooling groove 801 and the coolant in the spiral tube 4 can circulate to quickly take away the heat from the surface of the transducer 2, and the thermal conductive frame 8 can realize heat conduction to the coolant. Since the contact surface between the heat dissipating fins 9 and the thermal conductive frame 8 is large and tight, the heat dissipation area of ​​the thermal conductive frame 8 is greatly increased, further accelerating the heat dissipation, and effectively preventing the transducer 2 from seriously heating up for a long time and affecting its internal components.

[0025] Furthermore, one end of the spiral tube 4 is connected to the first bellows 5 through the annular tube 401, and the other end of the first bellows 5 is connected to the cooling groove 801 through the conduit 501, and the other end of the spiral tube 4 is fixedly connected to the second bellows 6, and the other end of the second bellows 6 is connected to the water outlet of the micro water pump 7 through the connecting pipe 601; the first bellows 5 and the second bellows 6 are both stainless steel bellows.

[0026] Furthermore, the diameter of the annular tube 401 is larger than the diameter of the spiral tube 4; the annular tube 401 is connected to the top of the inner wall of the sound insulation box 1 through a tube support 11, and three tube supports 11 are provided.

The coolant can continuously absorb its heat through the heat conduction plates 802 and the heat conduction frame 8 in the process of passing through the cooling channel, so the coolant can be quickly cooled down.

[0030] The working principle and operation steps of this specific implementation are:

[0031] When the transducer 2 generates heat, first, the spiral heat conductor 402 absorbs the heat on the surface of the transducer 2 and conducts it to the spiral tube 4, where it is absorbed by the coolant in the spiral tube 4. At the same time, the micro water pump 7 is turned on, and the micro water pump 7 sucks the coolant in the spiral tube 4 through the suction port in a vacuum negative pressure manner and directly transmits it to the cooling tank 801. During the transmission process through the cooling channel in the cooling tank 801, the coolant is continuously absorbed by the heat conduction plate 802 and the heat conduction frame 8, and then quickly cooled down. At the same time, the heat on the cooling frame is quickly conducted to the outside by the heat dissipation fins 9, and the heat dissipation fan 10 is turned on. When the heat dissipation fan 10 starts to rotate the fan blades, the air above the fan blades is sucked under the fan blades to form a forced airflow, which accelerates the air flow on the surface of the heat dissipation fins 9 and quickly takes away the hot air flow diffused from the heat dissipation fins 9 to complete the use.

After completion, start the ultrasonic generator to crush the cell sample to be crushed. After the crushing requirements are met, turn off the generator and take out the crushed cell sample.
