[0029] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or server including a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or modules not clearly listed or inherent to the process, method, product, or device.

[0030] With reference to Figure 1 , the ultrasonic extraction device for polymer detection in the embodiment comprises an ultrasonic assembly 1, a water storage assembly 2, and an extraction assembly 3. In the embodiment, the organic solvent to be detected is filled in the extraction assembly 3, and after ultrasonic oscillation in the ultrasonic assembly 1, extraction is performed in the extraction assembly 3, so as to reduce the residue of the organic solvent with the detected polymer in the ultrasonic bottle transfer process and improve the accuracy of detection. In addition, the water storage assembly 2 facilitates the transfer of ultrasonic water in the box 11 and improves the utilization rate of ultrasonic water.

[0031] Specifically, with reference to Figure 1 and Figure 2 , the ultrasonic assembly 1 comprises a box 11, an ultrasonic wave generator mounted on the box 11, and a connecting pipeline 12 connected to the box 11. The box 11 is provided with an ultrasonic cavity 111 for ultrasonic oscillation of the organic solvent. When the ultrasonic cavity 111 is filled with ultrasonic water, the extraction assembly 3 is placed in the ultrasonic cavity 111 for ultrasonic oscillation.

[0032] In combination with Figure 3 , the extraction assembly 3 comprises a lifting structure 31 connected to one side of the box 11 and an extraction bottle 32 mounted on the lifting structure 31. The extraction bottle 32 contains the organic solvent, and the extraction bottle 32 is located in the box 11 to realize ultrasonic oscillation and extraction. The lifting structure 31 comprises a fixed rod 311 fixed to one side of the box 11 and a positioning rod 312 slidably connected to the fixed rod 311. In combination with Figure 4The positioning rod 312 is provided with a positioning ring 313 fixedly connected with the extraction bottle 32, and the extraction bottle 32 is slid up and down through the positioning rod 312.

[0033] Further, the positioning rod 312 is integrally provided with a sliding block 314 on one side of the fixed rod 311, and the fixed rod 311 is provided with a sliding groove 315 for sliding of the sliding block 314. The groove bottom of the sliding groove 315 is provided with a limiting groove 3151, and the two sides of the sliding block 314 are provided with sliding blocks 3141 clamped in the limiting groove 3151, thereby reducing the probability of falling of the sliding block 314 from the sliding groove 315.

[0034] In addition, the fixed rod 311 is uniformly arranged with limiting blocks 316 on the circumferential side of the sliding groove 315, and the positioning rod 312 is arranged with a positioning block 317 fixedly cooperating with the limiting block 316 on the two sides of the sliding groove 315. The positioning block 317 includes a positioning portion 3171 and a holding portion 3172 integrally connected. The positioning rod 312 is arranged with an elastic member (not shown in the figure) on the direction of the positioning block 317, and the elastic member has a tendency to displace the positioning block 317 to the two sides, forcing the positioning portion 3171 to be fixed on the limiting block 316. The operator forces the positioning block 317 to displace to the direction of the positioning rod 312 by clamping the holding portion 3172 with the hand, thereby achieving unlocking of the positioning block 317 and the limiting block 316.

[0035] In addition, the positioning rod 312 is provided with a motor 318, and the length direction of the output shaft of the motor 318 is consistent with the length direction of the positioning rod 312.

[0036] In addition, the water storage assembly 2 comprises a water storage tank 21 connected with the connecting pipeline 12. One end of the connecting pipeline 12 communicates with the cavity of the box body 11, and the other end of the connecting pipeline 12 communicates with the cavity of the water storage tank 21. The cavity of the box body 11 communicates with the cavity of the water storage tank 21 through the connecting pipeline 12, and the connecting pipeline 12 is provided with a valve 121 for opening or closing the inner cavity of the connecting pipeline 12. The valve 121 controls the opening or closing of the inner cavity of the connecting pipeline 12, facilitating the transfer of the ultrasonic water in the box body 11.

[0037] Further, the water storage tank 21 is provided with a water pump 22 connected with the connecting pipeline 12. The water pump 22 is used to realize the transfer of the ultrasonic water between the ultrasonic cavity 111 and the cavity of the water storage tank 21, thereby improving the utilization rate of the ultrasonic water. In addition, the outside of the water storage tank 21 is provided with a control panel 23 electrically connected with the water pump 22, and the power of the water pump 22 for transferring the ultrasonic water is realized through the control panel 23.

[0038] In addition, with reference to Figure 2 In the embodiment, the operation panel 112 is arranged outside the box body 11. In the embodiment, the operation panel 112 can control the frequency of the ultrasonic waves in the ultrasonic cavity 111. In addition, the motor 318 on the lifting assembly can also be controlled by the operation panel 112, thereby improving the convenience of the ultrasonic extraction device.

[0039] With reference to Figure 4 The positioning member 321 is arranged on the side of the extraction bottle 32, and the positioning groove 322 for clamping the positioning ring 313 is arranged on the positioning member 321. In addition, the positioning ring 313 is a rubber ring with elasticity, which is fixed in the positioning groove 322, thereby connecting the extraction bottle 32 and the fixing rod 311. Further, the positioning ring 323 and the clamping member (not shown in the figure) are arranged on the positioning member 321. The positioning ring 323 and the positioning ring 313 are close to each other, and the clamping member clamps them at the same time, thereby improving the connection stability between the extraction bottle 32 and the fixing rod 311.

[0040] In combination with Figure 4 and Figure 5 The control valve 324 for controlling the flow of the organic solvent from the lower port is arranged on the bottle body of the extraction bottle 32. In addition, the cover 325 for closing the bottle opening of the extraction bottle 32 is arranged above the extraction bottle 32, and the cover 325 is connected to the bottle opening of the extraction bottle 32 in a hinged manner. The other end of the cover 325 is provided with the clamping member 326 for fixing the cover 325 to the bottle opening of the extraction bottle 32. Further, the sealing ring 327 is arranged on the cover 325, thereby reducing the probability of spilling the organic solvent from the bottle opening of the extraction bottle 32 when the motor 318 shakes the extraction bottle 32.
