[0002] Ultrasonic crushing devices are widely used in laboratories. They can be used to crush various animal and plant cells, virus cells, bacteria and tissues, as well as to crush and reorganize various inorganic substances. When the ultrasonic crushing device is operated, the electrical energy is converted into sound energy through the transducer. This energy passes through the liquid medium and becomes dense small bubbles. These small bubbles explode rapidly, thereby crushing cells and other substances.

[0003] When using an ultrasonic crushing device to conduct experiments, the direct contact between the ultrasonic probe and the sample will inevitably cause the sample to remain on the probe. In order to avoid affecting the next experiment, the cleaning of the probe is very important. However, the existing ultrasonic crushing devices usually do not have the function of automatically cleaning the probe, which causes inconvenience to the cleaning of the probe. Therefore, an ultrasonic crushing device is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 An ultrasonic crushing device in this embodiment includes a test box 1 and a control machine 2. A transducer 3 is arranged on the top of the test box 1. A wire is connected between the control machine 2 and the transducer 3. A crushing head 4 is arranged at the bottom of the transducer 3. An automatic cleaning mechanism 5 is arranged on the left side of the test box 1. A drainage mechanism 6 is arranged inside the test box 1.

[0023] The control machine 2 provides the required electrical energy to the transducer 3. At the same time, the user can precisely control the operation of the transducer 3 through the control machine 2. The transducer 3 converts the electrical energy into sound energy, that is, generates ultrasonic waves. The crushing head 4 transmits the generated ultrasonic energy to the sample on the supporting plate 604, thereby achieving sample crushing.

[0024] The automatic cleaning mechanism 5 includes a liquid storage tank 501 and a liquid suction pump 502. The liquid storage tank 501 is fixedly installed on the left side of the test box 1, and the liquid suction pump 502 is arranged on the top of the liquid storage tank 501. A liquid suction tube 503 is connected between the inlet of the liquid suction pump 502 and the liquid storage tank 501, and an infusion tube 504 is connected to the outlet of the liquid suction pump 502. A water collecting tray 505 is fixedly installed on the outer surface of the transducer 3, and a nozzle 506 is fixedly installed on the bottom of the water collecting tray 505.

[0025] The liquid storage tank 501 is used to store cleaning liquid. In order to facilitate the timely addition of cleaning liquid into the interior of the liquid storage tank 501, a transparent window and a digital scale bar are also provided on the front side of the liquid storage tank 501. By opening the sealing plug, cleaning liquid can be added into the liquid storage tank 501 from the filling port to ensure that sufficient cleaning liquid is stored in the liquid storage tank 501.

[0026] The interior of the water collecting tray 505 is a hollow structure. The suction pump 502 transports the cleaning liquid to the water collecting tray 505 through the suction tube 503 and the infusion tube 504, and then sprays the cleaning liquid onto the crushing head 4 through four inclined nozzles 506 at the bottom to comprehensively rinse the outer surface of the crushing head 4.

[0027] The drainage mechanism 6 includes a slide 601, which is fixedly installed on the inner top wall of the test box 1, a partition plate 602 located on the top of the slide 601 is fixedly installed between the left and right inner walls of the test box 1, a supporting plate 604 is movably installed on the top of the partition plate 602, and leakage holes 1 605 are evenly opened inside the supporting plate 604, and leakage holes 2 606 are evenly opened inside the partition plate 602. Drainage ports 607 are opened at the bottom of the left and right sides of the test box 1, and both sides of the top of the slide 601 are inclined structures.

[0028] The partition plate 602 separates the test area from the wastewater area to avoid affecting the electric push rod 603 and prevent cross contamination. The electric push rod 603 connected to the supporting plate 604 is fixedly installed inside the slide 601. The supporting plate 604 can move up and down to facilitate the contact between the sample and the crushing head 4.

[0029] The leakage hole 1 605 and the leakage hole 2 606 can overlap, which facilitates the waste water after flushing to flow into the slide 601 so that it can be discharged from the drain port 607.

[0030] When implementing, follow these steps:

[0031] 1) First, place the sample to be tested on the carrier plate 604, and drive the carrier plate 604 upward through the electric push rod 603, so that the crushing head 4 penetrates into the sample to perform ultrasonic crushing on it;

[0032] 2) After the test is finished, the load-bearing plate 604 returns to its original position, and the leakage hole 1 605 and the leakage hole 2 606 overlap;

[0033] 3) When the crushing head 4 needs to be cleaned, the cleaning liquid in the liquid storage tank 501 is firstly input into the water collecting tray 505 through the liquid suction pipe 503 and the liquid delivery pipe 504 by the liquid suction pump 502, and then sprayed on the crushing head 4 through the nozzle 506 at the bottom to wash the crushing head 4;

[0034] 4) The waste water after the final flushing falls onto the slide 601 through the leakage hole 1 605 and the leakage hole 2 606 , and is discharged from the two drain ports 607 along the slope of the slide 601 .

[0035] In summary, the ultrasonic crushing device, by providing an automatic cleaning mechanism 5, can transport the cleaning liquid in the liquid storage tank 501 to the water collecting tray 505, and spray it on the crushing head 4 through four inclined nozzles 506, so as to automatically clean the crushing head 4, effectively avoiding sample residue, thereby eliminating the risk of cross contamination that may be caused to subsequent tests. Since the cleaning process is automated, the user can easily complete the cleaning operation without manual intervention, thereby greatly improving work efficiency and experimental accuracy.

[0036] Furthermore, by providing a drainage mechanism 6, the cleaning liquid after cleaning can be discharged from the drainage ports 607 on both sides along the slope of the slide 601 through the drainage hole 1 605 and the drainage hole 2 606, thereby avoiding the accumulation of waste water inside the test box 1, thereby keeping the test box 1 clean and dry.
