Description

Technical Field

[0001] This utility model relates to the field of ultrasonic generator technology, and in particular to a multi-frequency drive device for an ultrasonic transducer. Background Technology

[0002] A multi-frequency drive unit for ultrasonic transducers is a device capable of providing drive signals at multiple frequencies, primarily used to control the operating state of ultrasonic transducers at different frequencies. This device typically consists of an ultrasonic generator and a transducer. By adjusting the output frequency of the generator, precise control of the transducer's operating frequency can be achieved. The ultrasonic generator converts electrical energy into a high-frequency AC signal that matches the ultrasonic transducer, thereby driving the transducer to operate.

[0003] Chinese utility model patent CN221832722U discloses an adjustable ultrasonic generator, including a base plate, a fixed seat fixedly connected to the base plate, a bracket fixedly connected to the base plate, a crossbeam fixedly connected to the bracket, a baffle slidably connected to the crossbeam, limiting sliders on both sides of the baffle, the limiting sliders slidably connected in the crossbeam, and heat dissipation holes on the baffle. When the ultrasonic generator is in use, the handle is pushed by hand to allow the heat dissipation holes on the baffle to communicate with the heat dissipation holes on the ultrasonic generator housing, thus not affecting the heat dissipation of the ultrasonic generator and facilitating the adjustment of the sealing state of the ultrasonic generator.

[0004] The ultrasonic generator mentioned above will vibrate when it is in operation. Since the baffle is slidably connected to the crossbeam through the limiting slider, the baffle will move under the action of vibration and block the heat dissipation hole, thereby reducing the heat dissipation effect of the generator. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a multi-frequency drive device for an ultrasonic transducer.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a multi-frequency driving device for an ultrasonic transducer, comprising a generator body, an adjustment knob for adjusting the frequency of the output electrical signal of the generator body, detection through holes communicating with the interior of the generator body on the side walls of both sides of the generator body, a dustproof plate abutting against the inner walls of both sides of the generator body and used to block the detection through holes inside the generator body, the dustproof plate being an inverted U-shaped structure, a breathable grille fixed to the inner wall of the detection through holes, and the top of the generator body... The unit is fixed with two sets of baffles symmetrically arranged about the middle of the dustproof plate. The two sides of the dustproof plate abut against the side walls of the two baffles respectively. Each side plate of the dustproof plate is provided with a mounting through hole. Each mounting through hole is provided with a heat dissipation component. The heat dissipation component includes a mounting block provided in the mounting through hole. Multiple heat dissipation through holes are provided through the mounting block. The distance between adjacent heat dissipation through holes is equal to the distance between adjacent strip through holes on the ventilation grille. The dustproof plate and the generator body are jointly provided with a lifting component for driving the dustproof plate to rise and fall so as to keep the dustproof plate in a stationary state.

[0007] By adopting the above technical solution, during the operation of the generator body, the lifting assembly drives the dustproof plate to descend, and the dustproof plate moves together with the mounting block connected to it until the heat dissipation holes align with the strip-shaped through holes. At this time, the hot air inside the generator body is discharged to the outside of the generator body through the heat dissipation holes and strip-shaped through holes. Since the lifting assembly can keep the dustproof plate in a stationary state, the normal heat dissipation of the device is ensured. After the generator body stops working, the lifting assembly drives the dustproof plate to move the mounting block up and reset. During this process, the heat dissipation holes and strip-shaped through holes change from an aligned state to a misaligned state. Since the dustproof plate abuts against the inner walls on both sides of the generator body and is used to block the detection through holes, the probability of dust entering the generator body is reduced.

[0008] Furthermore, the lifting assembly includes a threaded rod that passes through and is rotatably connected to the top of the horizontal section of the dustproof plate, an auxiliary knob fixed to the upper end of the threaded rod and coaxially arranged with the threaded rod, a horizontal plate fixed inside the generator body, and an internal threaded sleeve that passes through and is fixed to the top of the horizontal plate. The threaded rod and the internal threaded sleeve are threadedly connected.

[0009] By adopting the above technical solution, rotating the auxiliary knob drives the threaded rod to rotate. Since the threaded rod is threadedly connected to the internal threaded sleeve, the dustproof plate connected to the rotating threaded rod can rise or fall, thereby achieving the purpose of misalignment or alignment between the heat dissipation through hole and the detection through hole.

[0010] Furthermore, the heat dissipation component also includes a dustproof mesh fixed inside the heat dissipation holes.

[0011] By adopting the above technical solution, the dustproof mesh reduces the probability of dust entering the generator body when the heat dissipation holes and detection holes are aligned.

[0012] Furthermore, the side wall of the mounting through hole is provided with a plug-in through hole, and the side wall of the mounting block is fixed with a plug-in block that engages with the annular groove.

[0013] By adopting the above technical solution, the insertion through hole and the insertion block are designed so that the mounting block can be disassembled or installed from the mounting through hole.

[0014] Furthermore, multiple anti-slip strips are fixed on the side wall of the auxiliary knob, evenly distributed about the axis of the auxiliary knob.

[0015] By adopting the above technical solution, the anti-slip strip reduces the probability of slippage when rotating the auxiliary knob.

[0016] Furthermore, the distance between the side of the dustproof net furthest from the auxiliary knob and the inner wall of the generator body is 0.5-1cm.

[0017] By adopting the above technical solution, it is easy to remove the mounting block from the mounting through hole.

[0018] In summary, the present invention has the following beneficial effects: In this application, by setting up a lifting mechanism, the dustproof plate is kept in a stationary state after the heat dissipation through hole is aligned with the strip through hole, thereby ensuring the normal heat dissipation of the device.

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] like Figure 1-4 As shown in the illustration, this application discloses a multi-frequency driving device for an ultrasonic transducer, including a generator body 1, an adjustment knob, a dustproof plate 3, a baffle 5, a heat dissipation assembly 7, and a lifting assembly 8. The adjustment knob is disposed on the generator body 1 and is used to adjust the ultrasonic frequency output by the generator body 1 (the adjustment knob is electrically connected to an oscillation circuit disposed inside the generator; by adjusting the oscillation circuit, the generator outputs electrical signals of different frequencies, thereby realizing multi-frequency adjustment of the generator). Detection through holes 2 communicating with the interior of the generator body 1 are provided on the side walls on both sides of the generator body 1, and a breathable grille 4 is fixed to the inner wall of the detection through holes 2. The dustproof plate 3 is disposed inside the generator body 1, and the dustproof plate 3 abuts against the inner walls on both sides of the generator body 1 and is used to block the detection through holes 2. The dustproof plate 3 is an inverted U-shaped structure. Mounting through holes 6 are provided on both side plates of the dustproof plate 3, and the baffle 5 is fixed to the top of the generator body 1. The baffle 5 is provided and symmetrically arranged about the middle of the dustproof plate 3.

[0026] The dustproof plate 3 abuts against the side walls of the two baffles 5 on both sides. In this example, buffer assemblies are provided on both sides of the dustproof plate 3. Each buffer assembly includes a sealing sleeve, a sealing piston, a piston rod, a connecting block, and a buffer spring. The sealing sleeve is fixed to the bottom of the side plate of the dustproof plate 3, and the sealing piston is slidably connected inside the sealing sleeve. The piston rod is fixed to the bottom of the sealing piston and passes through the bottom of the sealing sleeve and slides. The connecting block is threaded onto the piston rod, and the buffer spring is sleeved on the piston rod and rotates between the sealing sleeve and the connecting block. The bottom of the generator is provided with sliding through holes for the connecting blocks to pass through. The number of sliding through holes is equal to the number of connecting blocks, and their positions correspond one-to-one.

[0027] The heat dissipation component 7 is disposed within the mounting through hole 6. The number of heat dissipation through holes 72 is equal to the number of heat dissipation components 7, and their positions correspond one-to-one. The heat dissipation component 7 includes a mounting block 71, which is disposed within the mounting through hole 6. Multiple heat dissipation through holes 72 are provided through the mounting block 71, and the distance between adjacent heat dissipation through holes 72 is equal to the distance between adjacent strip through holes on the ventilation grille 4.

[0028] The lifting assembly 8 is mounted on both the dustproof plate 3 and the generator body 1, and is used to drive the dustproof plate 3 to rise and fall while keeping it stationary. The lifting assembly 8 includes a threaded rod 81, an auxiliary knob 82, a horizontal plate 83, and an internally threaded sleeve 84. The threaded rod 81 passes through the top of the horizontal section of the dustproof plate 3 and is threadedly connected. The auxiliary knob 82 is fixed to the top of the threaded rod 81 and is coaxially mounted with the threaded rod 81. The horizontal plate 83 is fixed within the horizontal section of the detection through hole 2. The internally threaded sleeve 84 passes through the top of the horizontal plate 83 and is fixed. The threaded rod 81 and the internally threaded sleeve 84 are threadedly connected.

[0029] During the operation of the generator body 1, rotating the auxiliary knob 82 drives the threaded rod 81 to rotate. Since the threaded rod 81 is threadedly connected to the internal threaded sleeve 84, the dustproof plate 3, which is rotatably connected to the threaded rod 81, descends. The dustproof plate 3 drives the mounting block 71 connected to it to move together until the heat dissipation hole 72 is aligned with the strip-shaped through hole. At this time, the hot air inside the generator body 1 is discharged to the outside of the generator body 1 through the heat dissipation hole 72 and the strip-shaped through hole. Since the lifting component 8 can keep the dustproof plate 3 in a stationary state, it ensures the normal heat dissipation of the device. After the generator body 1 stops working, rotating the auxiliary knob 82 causes the threaded rod 81 to rotate in the opposite direction. Since the threaded rod 81 is threadedly connected to the internal threaded sleeve 84, the dustproof plate 3, which is rotatably connected to the threaded rod 81, rises and resets. During this process, the heat-perforated hole and the strip-shaped through hole change from an aligned state to a misaligned state. Because the dustproof plate 3 abuts against the inner walls on both sides of the generator body 1 and is used to block the detection through hole 2, the probability of dust entering the generator body 1 is reduced.

[0030] The heat dissipation assembly 7 also includes a dust filter 73, which is fixed inside the heat dissipation through-hole 72. The dust filter 73 reduces the probability of dust entering the generator body 1 when the heat dissipation through-hole 72 is aligned with the detection through-hole 2.

[0031] A insertion through hole 9 is provided on the side wall of the mounting through hole 6, and an insertion block 10 that engages with the annular groove is fixed on the side wall of the mounting block 71. The distance between the side of the dustproof net 73 away from the auxiliary knob 82 and the inner wall of the generator body 1 is 0.5-1cm. The insertion through hole 9 and the insertion block 10 are provided to allow the mounting block 71 to be removed or installed from the mounting through hole 6.

[0032] Multiple anti-slip strips, evenly distributed along the axis of the auxiliary knob 82, are fixed to the side wall of the auxiliary knob 82. The anti-slip strips reduce the probability of slippage when rotating the auxiliary knob 82.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
