[0018] Example 2 Reference Figure 1 to Figure 12 , which is the third embodiment of the present invention, and this embodiment is located above the previous embodiment.

[0019] Working principle: When the device is used to take samples for food quality inspection, the structural characteristics of the movable universal wheel 2 can be used to drive the supporting frame 1 to move stably and smoothly to the designated working position as a whole, open the sample storage protection door 16 of the liquid sample storage chamber 4 and the solid sample storage chamber 7, and use the alignment assembly interface 31 to perform a stable docking assembly operation with the alignment assembly joint 19, and the docking block 32 is aligned and inserted into the positioning slot 33, and is pushed to the end of the positioning slot 33 and then rotated, so that the docking block 32 is stably inserted into the rotating clamping slot 34, so that the sample storage container 20 can be stably assembled. The use effect of the external fastening assembly of the alignment assembly joint 19 is that water is added to the water storage chamber 6 through the water inlet pipe 11, and the liquid level sensor 15 can feedback the real-time water volume to the control panel 10. The evaporation heating component 14 is controlled to start by the control panel 10 to heat and evaporate the water inside the water storage chamber 6. The steam eruption pump 12 is controlled to start and emit the evaporated steam of the water inside the water storage chamber 6 from the associated three-way pipe 24 through the steam eruption conduit 25 to the sampling circulation pipeline 3, and enter the internal pipelines of the liquid sample storage chamber 4 and the solid sample storage chamber 7 respectively, so as to irrigate the pipelines and the sample storage container 20 and the multi-blade crusher. The shaft 37 performs a complete high-temperature disinfection operation, and the liquid assembly sampling head 39 and the solid assembly sampling head 40 are selected and assembled according to the state of the sampled food. The spring hose 30 can be appropriately stretched according to the specific use requirements. Under the strong suction of the sampling strong suction pump 9, when the liquid sample is sucked into the sampling branch conduit 22, the directional solenoid valve 41 on the side of the liquid sampling discharge pipe 28 is opened to allow the liquid sample to directly enter the sample storage container 20 in the liquid sample storage chamber 4. When the solid sample is sucked into the sampling branch conduit 22, the directional solenoid valve 41 on the side of the solid sampling discharge pipe 29 is opened to allow the solid sample to enter the liquid sample storage chamber 4 directly. The sample first enters the pulverizing processing chamber 5 for pulverizing processing, and the pulverizing drive motor 26 is started in a controlled manner to drive the transmission gear 35 to rotate, and uses its own meshing connection structure to drive the driven gear 36 to rotate, so that the multi-blade pulverizing shaft 37 pulverizes the solid sample, and enters the sample storage container 20 in the solid sample storage chamber 7 through the valve receiving pipe 27.
