Description

Technical Field

[0001] This utility model relates to an ultrasonic pulverizer, belonging to the field of pulverizer technology. Background Technology

[0002] In biological research, it is often necessary to study the cells of organisms in order to understand them and apply the research results to biology or medicine. In the process of cell research, it is necessary to break down the cells, which is often done using an ultrasonic cell disruptor.

[0003] The main component of an ultrasonic pulverizer is the transducer, which includes a high-frequency vibrating component and an actuating component. During pulverization, the vibrating component drives the actuating component to vibrate at high frequency to pulverize cells. In the prior art, the vibrating component and the actuating component are rigidly fixedly connected, which limits the amplitude of the actuating component's end, resulting in poor pulverization effect. At the same time, the component that fixes the transducer vibrates together, causing the entire pulverizer to vibrate, increasing noise. In addition, the actuating mechanism in the prior art has poor amplitude absorption capacity, which further easily causes the pulverizer to vibrate.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing an ultrasonic pulverizer that can reduce the overall amplitude of the transducer, making the operation more stable and reducing noise.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] An ultrasonic pulverizer has a frame structure. An installation cylinder is installed on the top wall of the frame structure. A transducer is installed inside the installation cylinder. The transducer includes a cylindrical fixed shell and an amplitude transformer rod that are installed together. The lower end of the fixed shell is open, and the upper end of the amplitude transformer rod is installed at the opening of the fixed shell.

[0008] The upper end of the amplitude rod is provided with a raised annular ring, the upper end of the raised ring is provided with a first shock-absorbing pad, and the lower end of the raised ring is provided with a second shock-absorbing pad.

[0009] Furthermore, the lower side of the inner wall of the fixed shell extends inward to form a retaining ring, the upper end of the first shock-absorbing pad abuts against the retaining ring, and the lower side of the second shock-absorbing pad is provided with a retaining spring, which is installed at the opening at the lower end of the fixed shell.

[0010] Furthermore, the cross-section of the raised ring is rectangular, and the cross-sections of both the first and second shock-absorbing pads are rectangular.

[0011] Furthermore, a metal retaining ring is provided between the second shock-absorbing pad and the retaining spring, and the metal retaining ring is made of aluminum alloy.

[0012] Furthermore, the luffing rod includes a rear section and a front section mounted at its front end, wherein the diameter of the front section is smaller than that of the rear section.

[0013] Furthermore, a protrusion is provided at the middle position of the rear section of the luffing rod.

[0014] Furthermore, the transducer also includes four layers of piezoelectric ceramic sheets disposed above the rear section of the amplitude transformer. The piezoelectric ceramic sheets are connected to the connecting copper sheets, and a rear end cover is installed at the rear end of the piezoelectric ceramic sheets.

[0015] Furthermore, a central hole is provided at the central axis of both the rear end cover and the piezoelectric ceramic sheet, and a threaded hole is provided at the upper end of the amplitude rod. A high-strength screw is threaded into the threaded hole, and the high-strength screw fixes the rear end cover and the piezoelectric ceramic sheet to the upper end of the amplitude rod.

[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0017] 1. The upper end of the amplitude transformer is provided with a raised annular ring, the upper end of the raised ring is provided with a first damping pad, and the lower end of the raised ring is provided with a second damping pad. The first and second damping pads play a role in damping vibration, thereby reducing the overall amplitude of the transducer, making the operation more stable and reducing noise.

[0018] 2. The diameter of the front section of the amplitude rod is smaller than that of the rear section. The front section of the amplitude rod is thinner and has a larger amplitude, which has a better effect on cell crushing. The rear section of the amplitude rod is thicker and has a relatively smaller amplitude, which reduces the vibration of the equipment. A protrusion is provided in the middle of the rear section of the amplitude rod to further reduce the vibration amplitude at the upper end of the rear section of the amplitude rod.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] like Figure 1 As shown, this utility model provides an ultrasonic pulverizer, including a frame structure 1, an mounting cylinder 2 installed on the top wall of the frame structure, and a transducer installed inside the mounting cylinder 2;

[0028] like Figure 2-4 The transducer includes a cylindrical fixed shell 3 and an amplitude transformer 4 installed together. The lower end of the fixed shell 3 is open, and the upper end of the amplitude transformer 4 is installed at the opening of the fixed shell 3.

[0029] The upper end of the amplitude rod 4 is provided with a raised annular protrusion ring 8, the upper end of the protrusion ring 8 is provided with a first shock-absorbing pad 9, and the lower end of the protrusion ring 8 is provided with a second shock-absorbing pad 10.

[0030] The lower side of the inner wall of the fixed shell 3 extends inward to form a retaining ring 301. The upper end of the first shock-absorbing pad 9 abuts against the retaining ring 301. The lower side of the second shock-absorbing pad 10 is provided with a retaining spring 12, which is installed at the opening at the lower end of the fixed shell 3.

[0031] like Figure 3 The cross-section of the protruding ring 8 is rectangular, and the cross-sections of the first shock-absorbing pad 9 and the second shock-absorbing pad 10 are both rectangular.

[0032] Furthermore, a metal retaining ring 11 is provided between the second shock-absorbing pad 10 and the retaining spring 12, and the metal retaining ring 11 is made of aluminum alloy.

[0033] The amplitude transformer 4 includes a rear section 401 and a front section 402 installed at its front end. The diameter of the front section 402 is smaller than that of the rear section 401. The thinner front section 402 results in a larger amplitude and better cell fragmentation, while the thicker rear section 401 results in a relatively smaller amplitude, reducing equipment vibration.

[0034] A protrusion 403 is provided in the middle of the rear section 401 of the amplitude rod. The protrusion 403 can absorb a certain amount of amplitude and reduce the vibration amplitude of the upper end of the rear section 401 of the amplitude rod.

[0035] The transducer also includes four layers of piezoelectric ceramic sheets 5 disposed above the rear section 401 of the amplitude transformer. The piezoelectric ceramic sheets 5 are connected to the connecting copper sheet 13, which supplies power to the piezoelectric ceramic sheets 5. A rear end cover 6 is installed at the rear end of the piezoelectric ceramic sheets 5.

[0036] Both the rear end cover 6 and the piezoelectric ceramic sheet 5 have a central hole at their central axis. The upper end of the amplitude rod 4 has a threaded hole with a high-strength screw 7 threaded into it. The high-strength screw 7 fixes the rear end cover 6 and the piezoelectric ceramic sheet 5 to the upper end of the amplitude rod 4.

[0037] The specific working principle of this utility model:

[0038] The transducer is installed inside the mounting cylinder 2. The transducer includes a fixed shell 3 and an amplitude transformer 4. The upper end of the amplitude transformer 4 is provided with a raised annular ring 8. The upper end of the raised ring 8 is provided with a first damping pad 9, and the lower end of the raised ring 8 is provided with a second damping pad 10. The first damping pad 9 and the second damping pad 10 play a role in damping vibration, thereby reducing the overall amplitude of the transducer, making the operation more stable, and reducing noise.

[0039] The amplitude transformer 4 includes a rear section 401 and a front section 402 mounted at its front end. The diameter of the front section 402 is smaller than that of the rear section 401. The thinner front section 402 results in a larger amplitude and better cell fragmentation, while the thicker rear section 401 results in a relatively smaller amplitude, reducing equipment vibration. A protrusion 403 is provided in the middle of the rear section 401, which can absorb a certain amount of amplitude, reducing the vibration amplitude at the upper end of the rear section 401.

The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
