Description

Technical Field

[0001] The present invention relates to the technical field of active noise reduction, and specifically to a noise reduction base for medical devices. Background Art

[0002] In medical devices, the design and function of the base are often crucial for the stability of the device and noise control, providing a quieter treatment environment for patients, which is conducive to their relaxation and recovery. At the same time, for medical staff working in a high-noise environment, it can also provide a more comfortable working environment, which is beneficial to improving work efficiency and medical quality. Active noise reduction is one type of noise reduction technology. Active noise reduction technology not only helps to reduce noise but also enhances the overall performance of medical devices. For example, in precision medical equipment, reducing noise can reduce interference with the device and improve the accuracy and stability of the device.

[0003] Prior Art 1 (Chinese Patent with Publication No. CN112128523A and Publication Date of December 25, 2020): A shock-absorbing base for a large medical device, including a base. The top of the base is fixedly installed with a bottom box through legs. On both sides of the bottom of the bottom box, a first threaded rod and a second threaded rod are respectively arranged, and the first threaded rod is located on the right side of the second threaded rod. The tops of the first threaded rod and the second threaded rod both penetrate the bottom plate of the bottom box and extend into the interior of the bottom box.

An adjusting roller groove is opened on the outside of the rotating roller, and a nested block is nested and connected inside the adjusting roller groove, and an outer ring is fixedly connected to the outer end of the nested block, and at the same time the outer ring is nested and connected to the outside of the rotating roller.

[0009] Preferably, a limiting shaft is fixedly connected between the inner sides of the adjusting plates, a fixing seat is fixedly connected to the upper surface of the base body, the limiting shaft is nested and connected inside the limiting shaft, and the upper end of the fixing frame is fixedly connected to the lower surface of the box body.

[0010] Preferably, the adjusting roller groove is inclinedly opened in a circle on the outside of the rotating roller, the nested block drives the outer ring and the rotating roller to form a sliding structure through the adjusting roller groove, the resisting rod forms a sliding structure with the resisting groove through the outer ring, and the adjusting plate drives the limiting shaft and the fixing seat to form a rotating structure through the resisting rod.

[0011] Preferably, the pushing mechanism includes a semi-gear, the semi-gear is fixedly connected to the lower side of the adjusting plate, an extrusion plate is fixedly connected between the sides of the two toothed plates, a first air bag is fixedly connected to the side of the fixing seat, and a connecting hose penetrates through the upper side of the extrusion plate. A sliding plate is fixedly connected to the inner side of the player, and the lower end of the sliding plate is nested and connected to the bottom side inside the box body, and a second air bag is fixedly connected between the inner side of the sliding plate and the inside of the box body. The upper end of the connecting hose penetrates and is connected to the second air bag.

[0012] Preferably, the semi-gear meshes with the toothed plate, and the toothed plate forms a sliding structure with the fixing frame through the semi-gear, and the first air bag is located inside the extrusion plate.

[0013] Preferably, the second air bag is communicated with the first air bag through the connecting hose, and the sliding plate forms a sliding structure with the box body through the second air bag.

[0015] Preferably, the abutment plate is located below the cam, the slide rod forms an elastic structure with the connecting tube via a spring, and the slide rod forms a sliding structure with the connecting tube via a linkage plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects: A box is provided on the upper surface of the base body, and a player is provided inside the box. By utilizing the principle of sound wave superposition and cancellation, the device monitors the ambient noise in real time through a built-in microphone, and converts these signals into antagonistic sound waves. The anti-phase sound waves are then accurately emitted through the player. Since the anti-phase sound waves have opposite phases to the original noise sound waves, they cancel out the original noise sound waves, achieving a noise reduction effect.

[0017] Start the motor, and the output end of the motor will synchronously drive the rotating roller to rotate. At this time, the adjusting roller groove opened on the outside of the rotating roller will contact the nesting block set on the inside of the ring, thereby driving the ring to move through the nesting block. When the ring is moving, it will synchronously drive the adjustment mechanism to operate, so that the adjustment plate drives the box to swing. When the box swings, it will drive the player to swing, thereby expanding the playback range of the player, further expanding the propagation range of the anti-phase sound wave, and improving the noise reduction effect.

[0018] When the ring moves, it will synchronously drive the resistance rod set on the side to move. At this time, the resistance rod will slide inside the resistance groove, thereby interfering with the upper side of the adjustment plate. When the upper end of the adjustment plate is rotated by force, it will synchronously drive the limit shaft to rotate inside the fixed seat. The rotating adjustment plate can be limited by the fixed seat, thereby improving the stability of the player's swing.

[0019] When the fixed seat rotates, it will synchronously drive the half gear set at the lower end to rotate back and forth synchronously. During the rotation process, the half gear will synchronously drive the tooth plate meshing with it to move along the fixed frame to limit the position. When the tooth plate moves, it will drive the extrusion plate to squeeze the first airbag, so that the gas inside the first airbag is transported to the inside of the second airbag through the connecting hose. At this time, the second airbag expands, thereby resisting the sliding plate, causing the sliding plate to move along the inside of the box. When the sliding plate moves, it will synchronously drive the player to move outward, so that the player can play the reverse sound waves better.

[0020] When the rotating roller rotates, it will synchronously drive the connecting shaft to rotate. When the connecting shaft rotates, it will drive the cam to rotate. At this time, the cam will reciprocately resist the contact plate. The contact plate will drive the sliding rod to move downward when it is resisted. When the contact plate is not resisted, the sliding rod will move up and reset along the connecting tube under the drive of the elastic force of the spring, thereby further driving the push plate set inside the connecting tube to move up and extract the air inside the connecting tube. By extracting air, the adsorption effect of the suction cup on the ground can be further improved, and the stability of the base body can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

The outside of the fixed frame 4 is fixedly connected with a motor 8, and one end of the rotating roller 9 is fixedly connected to the output end of the motor 8. An adjusting roller groove 27 is opened on the outside of the rotating roller 9, and a nested block 11 is nested and connected inside the adjusting roller groove 27, and the outer end of the nested block 11 is fixedly connected with a collar 10. At the same time, the collar 10 is nested and connected on the outside of the rotating roller 9. A contact groove 13 is opened on the upper side of the adjusting plate 5, and a contact rod 12 is nested and connected inside the contact groove 13, and the inner end of the contact rod 12 is fixedly connected to the outside of the collar 10.

Using the principle of acoustic wave superposition and cancellation, the ambient noise is monitored in real time through a microphone built in the device, and these signals are converted into antagonistic sound waves, that is, anti-sound waves, and then the anti-sound waves are accurately emitted through the player 7. Since the phase of the anti-sound wave is opposite to that of the original noise sound wave, the original noise sound wave is cancelled, achieving a noise reduction effect.

At this time, the adjusting roller groove 27 opened on the outer side of the rotating roller 9 will abut against the nested block 11 arranged inside the collar 10, so as to drive the collar 10 to move through the nested block 11. When the collar 10 is moving, it will synchronously drive the adjustment mechanism to operate, so that the adjusting plate 5 drives the box body 6 to swing. When the box body 6 swings, it will drive the player 7 to swing, thereby expanding the playing range of the player 7 and further expanding the propagation range of the anti-sound wave, improving the noise reduction effect. When the collar 10 moves, it will synchronously drive the abutting rod 12 arranged on the side to move. At this time, the abutting rod 12 will slide inside the abutting groove 13, so as to abut against the upper side of the adjusting plate 5. When the upper end of the adjusting plate 5 is stressed and rotates, it will synchronously drive the limiting shaft 18 to rotate inside the fixed seat 15.

During the rotation process, the half gear 26 will synchronously drive the toothed plate 14 meshing with it to move along the fixed frame 4. When the toothed plate 14 moves, it will drive the extrusion plate 24 to squeeze the first airbag 16, so that the gas inside the first airbag 16 is transported to the inside of the second airbag 17 through the connecting hose 29. At this time, the second airbag 17 expands, thereby resisting the sliding plate 28, so that the sliding plate 28 moves along the inside of the box 6.
