[0028] Refer to Figure 1 , 2 , here is an example of the implementation manner of the main body:

[0029] An electric telescopic vibration motor 9 includes a telescopic part and a driving part. The telescopic part includes a telescopically integrated telescopic box 1 and a telescopic base 2. The lower end of the telescopic base 2 is slidably sleeved with a telescopic bottom shell 3. Inside the telescopic bottom shell 3, a telescopic component that cooperates with the telescopic base 2 is rotatably connected. The telescopic component is used to drive the telescopic sliding between the telescopic base 2 and the telescopic bottom shell 3. A vibration motor 9 is fixedly clamped inside the telescopic box 1; the driving part includes a driving motor 6. The output end of the driving motor 6 is drivingly installed with a reduction gearbox 5. Inside the reduction gearbox 5, a gear assembly is rotatably installed. The gear assembly is used for speed change. The output end of the gear assembly is fixedly connected with a main shaft 7 extending outside the reduction gearbox 5. One end of the main shaft 7 penetrates through the telescopic bottom shell 3 and is drivingly connected with the telescopic component;

[0030] Based on the above content, a sliding slot 802 and other common structures can be provided between the telescopic base 2 and the telescopic bottom shell 3 to form a telescopic combination. The vibration motor 9 provided inside the telescopic box 1 enables the device to have a vibration function. The combination of the above two jointly realizes the basic functions of telescoping and vibrating; a brush head connecting piece and other structures can be installed at the front end of the telescopic box 1, so that the brush head has the functions of telescoping and vibrating, and can better clean the stains on the surface of the item;

[0031] Further, a rotating bead seat 4 is fixedly installed on the lower end surface of the telescopic bottom shell 3. Inside the rotating bead seat 4, multiple groups of beads 401 are rotatably installed. One end of the main shaft 7 passes through the rotating bead seat 4 and extends into the telescopic bottom shell 3. Since the product is usually sleeved with a decorative outer shell during actual use, the beads 401 provided in the rotating bead seat 4 can be in sliding contact with the external shell, improving the stability of the combination of the telescopic box 1, the telescopic base 2, and the telescopic bottom shell 3;

[0032] Further, a placement groove is integrally formed inside the telescopic box 1 for fixing the vibration motor 9. The vibration motor 9 can be a common eccentric motor or a rotor motor;

[0033] Further, a limiting sliding groove should be provided between the telescopic base 2 and the telescopic bottom shell 3 to ensure the stability of their sliding, and only allow the telescopic base 2 and the telescopic bottom shell 3 to slide but not rotate;

[0034] Furthermore, when performing external packaging and decoration, the telescopic base 2 and the telescopic bottom shell 3 should be respectively connected to two groups of movable parts, or only one of the parts is connected to the packaging and decoration part, to ensure that the telescopic base 2 and the telescopic bottom shell 3 can slide and expand normally;

[0035] Further, the main shaft 7 is of a hollow structure. A through hole is provided on the outer end face of the reduction gearbox 5. The input end of the vibration motor 9 is electrically welded with a power cord 10. The power cord 10 passes through the main shaft 7 and the through hole and extends to the outside of the reduction gearbox 5 to supply electrical energy to the vibration motor 9. A waterproof rubber ring should be provided in the through hole.

[0036] Refer to Figure 2 、 3 Here is an example of the implementation manner of the telescopic assembly:

[0037] The telescopic assembly includes a rotating shaft 8. A sliding groove 802 is provided on the outer peripheral end face of the rotating shaft 8. A sliding block 803 is slidably connected inside the sliding groove 802. One outer end of the sliding block 803 is rotatably connected to the inside of the telescopic base 2. A plugging groove 801 for inserting the main shaft 7 is provided through the middle of the rotating shaft 8;

[0038] Further, two groups of sliding blocks 803 are provided on the left and right. The cross-section of the sliding block 803 is a rhombus structure;

[0039] Further, the sliding groove 802 is a spiral groove structure formed by four groups staggered around the outer peripheral end face of the rotating shaft 8. Multiple groups of sliding grooves 802 together form multiple interconnected "8"-shaped structures, so as to realize the reciprocating sliding of the sliding block 803 in the sliding groove 802, so that the rotating shaft 8 only needs to rotate continuously in the same direction to drive the sliding block 803 to move reciprocally.

[0040] Refer to Figure 2 Here is an example of the implementation manner of the gear assembly:

[0041] The gear assembly includes two groups of first central shafts 501 and second central shafts 502 that are horizontally rotatably connected inside the reduction gearbox 5. Four groups of mutually cooperating double gears 504 are rotatably sleeved around the peripheries of the first central shaft 501 and the second central shaft 502. The first central shaft 501 is fixedly connected to the output shaft of the drive motor 6. A main output gear 503 connected to the main shaft 7 is fixedly installed at the output end of the second central shaft 502. The double gears 504 located at the end of the first central shaft 501 and at the front end of the second central shaft 502 should be fixedly connected so as to be able to drive the second central shaft 502 and the first central shaft 501 to rotate;

[0042] Based on the above content, the output shaft of the drive motor 6 drives a group of first central shafts 501 to rotate. The first central shaft 501 drives a group of double gears 504 to rotate, enabling this group of double gears 504 to drive a group of double gears 504 on the second central shaft 502 to rotate. This group of double gears 504 continues to drive another group of double gears 504 on the first central shaft 501 to rotate, thereby driving the main output gear 503 and the main shaft 7 to rotate. Among them, the double gears 504 should have two sets of gears with different sizes to achieve a speed-changing effect;

[0043] Further, a copper sleeve 505 is fixedly sleeved around the periphery of the main shaft 7 inside the reduction gearbox 5 to improve the sealing performance.

[0044] Finally supplemented:

[0045] The main shaft 7 and the ball seat 4 can be rotatably connected or fixedly connected. When the main shaft 7 is fixedly connected to the ball seat 4, the balls 401 should contact the external components. When the main shaft 7 is rotatably connected to the ball seat 4, the balls 401 should contact the main shaft 7. This is an optional structure of the combination of the ball seat 4 and the balls 401 during production.

[0046] Based on the above examples of each embodiment, when in use:

[0047] Place the device inside an external component or a decorative shell, and connect the telescopic base 2 and the telescopic bottom shell 3 to different external movable parts respectively; the provided balls 401 can be in sliding contact with the external component or the decorative shell, playing a role in improving stability; starting the vibration motor 9 can achieve the vibration effect at the top. Start the drive motor 6. After the speed change by the gear assembly, the drive motor 6 drives the main shaft 7 to rotate, enabling the rotating shaft 8 and the sliding block 803 to cooperate with each other to slide, so that there is a telescopic effect between the telescopic base 2 and the telescopic bottom shell 3;

[0048] The front end of the telescopic box 1 of the device can be plugged and extended, such as plugging in a brush head to play a cleaning role.

[0049] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
