Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a vibration motor with a dustproof function. Background Art

[0002] A vibration motor is an electric motor that combines the principles of electromagnetic force and mechanical vibration. The main structure of this device includes a fixed iron core, a coil wound with copper wire, and a rotatable eccentric wheel. When current passes through the coil, a rotating magnetic field is generated, which causes the eccentric wheel to be unbalanced, thereby generating vibration. By adjusting the magnitude and frequency of the current, the vibration amplitude and frequency of the vibration motor can be controlled. Vibration motors are widely used in many industries, such as coal, metallurgy, building materials, chemicals, etc., for operations such as material transportation, screening, and sorting. Their characteristics include large amplitude, adjustable vibration frequency, low noise, and long service life. The working principle of the vibration motor is to drive the eccentric block through the rotation of the motor, which in turn causes the bearing to vibrate eccentrically to achieve the vibration function.

[0003] Some existing vibration motors are provided with dustproof mechanisms when in use. However, the dustproof mechanisms are usually closed structures, and air cannot circulate normally, which is not conducive to heat dissipation inside the dustproof mechanisms.

[0004] For example, a vibration motor with a dustproof function is disclosed with announcement number CN219717996U. The patent has an open end at which the protective cover is away from the motor body and is hinged with a protective plate. A sealing ring is provided on the side of the protective plate near the protective cover to improve the dustproof effect of the motor. A locking mechanism is provided on one side of the limiting plate near the bottom. One end of the protective plate is locked with the locking mechanism. The protective plate can be easily opened during use, and the exciting force of the vibration motor can be adjusted without removing the entire protective cover.

[0005] Although the protective cover of this patent has a dust-proof effect by providing an openable and closable protective plate, when the protective plate is closed, the inside of the protective cover becomes a closed environment and air cannot circulate normally, which is not conducive to heat dissipation inside the protective cover.

[0006] Therefore, it is necessary to invent a vibration motor with dustproof function to solve the above problems. Utility Model Content

[0036] In one aspect of the present embodiment, the clamping mechanism 6 includes a receiving groove 8, which is arranged inside the dustproof baffle 4. A movable groove 9 is arranged on the surface of the dustproof baffle 4, and the movable groove 9 is connected with the receiving groove 8. A plug-in rod 10 and an extrusion spring 11 are arranged inside the receiving groove 8. One end of the plug-in rod 10 passes through the receiving groove 8 and extends to the outside of the dustproof baffle 4. The extrusion spring 11 is sleeved on the other end of the plug-in rod 10. A handle 12 is arranged on the surface of the dustproof baffle 4. The bottom end of the handle 12 passes through the movable groove 9 and extends to the inside of the receiving groove 8. The bottom end of the handle 12 is fixedly connected to the plug-in rod 10. One end of the extrusion spring 11 abuts against the inner wall of the receiving groove 8, and the other end of the extrusion spring 11 abuts against the bottom end of the handle 12.

[0037] Working principle of this utility model:

[0038] Refer to the instruction manual Figure 1-5When using the utility model, first put the filter screen plate 5 into the operation port of the dust cover 2, and then put the dust baffle plate 4 into the operation port, and use the clamping mechanism 6 to limit and fix the dust baffle plate 4, the filter screen plate 5 is clamped between the dust baffle plate 4 and the limiting ring 3, and the surface of the dust baffle plate 4 is provided with a ventilation groove 7, and a shielding strip eaves 15 are arranged above the ventilation groove 7.

[0039] When adjusting the eccentric block on the motor body 1, the plug-in rod 10 can be pulled through the handle 12 to retract one end of the plug-in rod 10 into the dust baffle 4. At this time, the extrusion spring 11 is in a contracted state. After losing the fixation of the clamping mechanism 6, the dust baffle 4 can be removed from the operating port, and then the filter screen plate 5 can also be taken out. At this time, the operating port is fully open, and the staff can adjust the eccentric block through the operating port. During this process, the dust baffle 4 and the filter screen plate 5 can also be cleaned.
