Description

Technical Field

[0001] This application relates to the field of acoustic motors, and in particular to a magnetically levitated acoustic motor. Background Technology

[0002] A magnetic levitation sonic motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Its main function is to generate driving torque, thereby enabling the magnetic levitation sonic motor to produce stable high-frequency vibrations. Therefore, it is widely used in high-frequency vibration appliances such as sonic toothbrushes and automatic shavers.

[0003] Current magnetic levitation acoustic motors generate high-frequency vibrations by setting two iron cores on the rotor instead of multiple iron cores, thereby driving high-frequency vibrating electrical appliances. However, existing magnetic levitation acoustic motors do not have an automatic lubrication function. Due to the small rotation amplitude and high rotation frequency of the bearings, the high-frequency vibrations after long-term operation will cause severe wear on the bearings, reducing their service life and causing the magnetic levitation acoustic motor to stop working, which is not conducive to its use. Summary of the Invention

[0004] The purpose of this application is to provide a magnetic levitation acoustic motor with an automatic lubrication function, which prevents severe wear of the bearings after long-term use and improves the service life of the acoustic motor.

[0005] To achieve the above objectives, this application also provides a magnetic levitation acoustic motor, including a housing, an end cap fitted on the right side of the housing, a rotor disposed in the inner cavity of the housing, the left side of the rotor extending to the outer side of the housing, a bearing for cooperating with the rotor fixedly connected to the left side of the housing, a fixed shell fixedly connected to the left side of the housing, storage shells fixedly connected to the front and rear sides of the inner cavity of the fixed shell, springs disposed in the inner cavity of the storage shell, pistons fixedly connected to opposite sides of the two springs, push blocks fixedly connected to opposite sides of the two pistons, pressure plates disposed on opposite sides of the two push blocks, the side of the pressure plate away from the push blocks fixedly connected to the rotor, a vent hole opened at the top of the piston away from the storage shell, a sealing gasket fixedly connected to the top of the inner wall of the piston, the bottom of the storage shell communicating with the bearing through an oil injection pipe, and an anti-detachment component disposed at the top of the inner cavity of the fixed shell.

[0006] Preferably, the anti-detachment component includes a screw, the front and rear sides of which are movably connected to the inner wall of the fixing shell. A knob is fixedly connected to the surface of the screw, the top of which extends through to the outer side of the fixing shell. Threaded sleeves are threadedly connected to the front and rear sides of the screw surface. Connecting rods are fixedly connected to the bottom of the threaded sleeves. Compression blocks are fixedly connected to opposite sides of the two connecting rods, and opposite sides of the two compression blocks extend through to the outer side of the fixing shell.

[0007] Preferably, a positioning rod is provided on the right side of the screw, and the front and rear sides of the positioning rod are fixedly connected to the inner wall of the fixed shell. The front and rear sides of the positioning rod are slidably connected to positioning sleeves, and the left side of the positioning sleeve is fixedly connected to the threaded sleeve.

[0008] Preferably, the side of the extrusion block away from the connecting rod is fixedly connected with anti-slip teeth, and the front and rear sides of the fixed shell are provided with movable openings that cooperate with the extrusion block.

[0009] Preferably, the top of the storage shell on the side away from the piston is connected to a delivery pipe, and the opposite ends of the two delivery pipes both penetrate the fixed shell and are connected to an oil delivery device.

[0010] Preferably, the push block is trapezoidal in shape, and cylindrical pressure blocks are fixedly connected to the opposite sides of the two pressure plates. The sealing gasket is made of soft rubber material.

[0011] Preferably, the front and rear sides of the spring are fixedly connected to the storage shell and the piston, respectively, and sealing rings are fixedly connected to opposite sides of the two pistons.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting up a fixed shell, storage shell, spring, piston, push block, pressure plate, vent hole, sealing gasket, oil injection pipe and anti-detachment component, it is possible to control the two pressure plates to continuously squeeze the push block when the rotor is working. The push block is squeezed to control the piston to move. Each time the piston moves, the lubricating oil inside the storage shell is delivered to the bearing through the oil injection pipe, so that the bearing is lubricated every time the rotor works, thus improving its service life.

[0014] 2. The delivery pipe facilitates the injection of lubricating oil into the inner cavity of the storage shell. The oil feeder, working in conjunction with the delivery pipe, utilizes a background program within the sonic motor's internal control system to periodically and quantitatively inject lubricating oil into the storage shell. The trapezoidal pusher allows the pressure plate with the cylindrical pressure block to press against its inclined surface, controlling the piston's movement. The sealing gasket facilitates the delivery of external air to the inner cavity of the storage shell each time the piston resets. The spring ensures the piston resets even when not under pressure. The sealing ring enhances the piston's sealing effect. After placing the housing in the installation position, rotating the knob, in conjunction with the screw, controls the movement of the threaded sleeve and connecting rod. The connecting rod's movement controls the pressing block to press against the inner wall of the groove at the housing's installation position, improving the stability of the housing installation and preventing loosening during operation, thus enhancing its overall stability after installation.

[0023] The technical solutions in the embodiments of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the embodiments described in this application are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a magnetic levitation acoustic motor, including a housing 1, an end cap 2 fitted on the right side of the housing 1, a rotor 3 disposed in the inner cavity of the housing 1, the left side of the rotor 3 extending to the outer side of the housing 1, a bearing 4 for use with the rotor 3 fixedly connected to the left side of the housing 1, a fixed shell 5 fixedly connected to the left side of the housing 1, a storage shell 6 fixedly connected to the front and rear sides of the inner cavity of the fixed shell 5, a spring 7 disposed in the inner cavity of the storage shell 6, a piston 8 fixedly connected to the opposite side of the two springs 7, a push block 9 fixedly connected to the opposite side of the two pistons 8, a pressure plate 10 disposed on the opposite side of the two push blocks 9, the side of the pressure plate 10 away from the push block 9 fixedly connected to the rotor 3, a vent hole 11 opened on the top of the side of the piston 8 away from the storage shell 6, a sealing gasket 12 fixedly connected to the top of the inner wall of the piston 8, the bottom of the storage shell 6 connected to the bearing 4 through an oil injection pipe 13, and an anti-detachment component 14 disposed on the top of the inner cavity of the fixed shell 5.

[0025] Example 1: By setting a fixed shell 5, a storage shell 6, a spring 7, a piston 8, a push block 9, a pressure plate 10, a vent 11, a sealing gasket 12, an oil injection pipe 13, and an anti-detachment component 14, the two pressure plates 10 can be controlled to continuously squeeze the push block 9 when the rotor 3 is working. The push block 9 is squeezed to control the piston 8 to move. Each time the piston 8 moves, the lubricating oil inside the storage shell 6 is transported to the bearing 4 through the oil injection pipe 13, so that the bearing 4 is lubricated every time the rotor 3 works, thereby improving its service life.

[0026] In one feasible implementation, please refer to Figure 1-5A magnetic levitation acoustic motor has a storage shell 6 with a top of the side away from the piston 8 connected to a delivery pipe 15. The opposite ends of the two delivery pipes 15 pass through the fixed shell 5 and are connected to an oil feeder. The push block 9 is trapezoidal in shape. The opposite sides of the two pressure plates 10 are fixedly connected to cylindrical pressure blocks. The sealing gasket 12 is made of soft rubber material. The front and rear sides of the spring 7 are fixedly connected to the storage shell 6 and the piston 8, respectively. The opposite sides of the two pistons 8 are fixedly connected to sealing rings.

[0027] Example 2: By setting up a delivery pipe 15, lubricating oil can be easily injected into the inner cavity of the storage shell 6. By setting up an oil feeder, it can cooperate with the delivery pipe 15. Using the background program set by the control system inside the sonic motor, lubricating oil is input into the storage shell 6 in a timed and quantitative manner. By setting up a trapezoidal pusher 9, the pressure plate 10 with the cylindrical pressure block can be pressed against its inclined surface, so as to control the movement of the piston 8. By setting up a sealing gasket 12, it is convenient to deliver external air to the inner cavity of the storage shell 6 each time the piston 8 resets. By setting up a spring 7, the piston 8 can be reset when it is not compressed. By setting up a sealing ring, the sealing effect of the piston 8 can be increased.

[0028] Based on Embodiment 1, this embodiment describes the anti-detachment component 14 in Embodiment 1. The anti-detachment component 14 includes a screw 1401, the front and rear sides of which are movably connected to the inner wall of the fixing shell 5. A knob 1402 is fixedly connected to the surface of the screw 1401, and the top of the knob 1402 extends to the outside of the fixing shell 5. Threaded sleeves 1403 are threadedly connected to the front and rear sides of the screw 1401. Connecting rods 1404 are fixedly connected to the bottom of the threaded sleeves 1403. Compression blocks 1405 are fixedly connected to opposite sides of the two connecting rods 1404, and opposite sides of the two compression blocks 1405 extend to the outside of the fixing shell 5. A positioning rod 1406 is provided on the right side of the screw 1401. The front and rear sides of the positioning rod 1406 are... The positioning rod 1406 is fixedly connected to the inner wall of the fixed housing 5. The front and rear sides of the positioning rod 1406 are slidably connected to the positioning sleeve 1407. The left side of the positioning sleeve 1407 is fixedly connected to the threaded sleeve 1403. The side of the extrusion block 1405 away from the connecting rod 1404 is fixedly connected to the anti-slip teeth. The front and rear sides of the fixed housing 5 are provided with movable openings that cooperate with the extrusion block 1405. After the housing 1 is placed in the installation position, the knob 1402 is rotated. The knob 1402 cooperates with the screw 1401 to control the movement of the threaded sleeve 1403 and the connecting rod 1404. The movement of the connecting rod 1404 controls the extrusion block 1405 to extrude the inner wall of the groove at the installation position of the housing 1, thereby improving the stability of the installation of the housing 1 and preventing it from loosening during operation, thus improving its stability after fixing.

[0029] Working principle: Place the housing 1 inside the groove at the installation position, then turn the knob 1402. The knob 1402 drives the screw 1401 to rotate. The rotation of the screw 1401 controls the movement of the two threaded sleeves 1403 and the connecting rod 1404. The movement of the connecting rod 1404 drives the extrusion block 1405 to move out of the inner cavity of the fixed housing 5, so that the two extrusion blocks 1405 extrude against the inner wall of the groove, improving the stability of the installation of the housing 1 and preventing it from loosening during operation. After the rotor 3 has been working for a period of time, under the control of the background program set in the control system inside the sonic motor, the lubricating oil is delivered by the oil conveyor and the delivery pipe 15. The lubricating oil is transported into the storage shell 6. The rotor 3 drives the pressure plate 10 to move, and the pressure plate 10 squeezes the push block 9. After being squeezed, the push block 9 drives the piston 8 to compress the spring 7. At the same time, the piston 8 delivers the lubricating oil stored in the storage shell 6 to the oil injection pipe 13. The oil injection pipe 13 injects the lubricating oil into the bearing 4 for lubrication. The rotor 3 moves a short distance each time, so the amount of lubricating oil injected each time is small, which can continuously lubricate and improve the service life of the bearing 4. When not lubricating, the pressure plate 10 and the push block 9 cooperate to limit the two sides of the rotor 3, increasing the stability of the rotor 3 during operation, so that the sonic motor can work stably for a long time.

[0030] Although embodiments of the present utility have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present utility, the scope of which is defined by the appended claims and their equivalents.
