Description

Technical Field

[0001] The utility model relates to the technical field of micro motors, and particularly relates to a micro motor for a massager with a dust-proof function. Background Art

[0002] The micro motor for a massager is mainly used to provide the power source for the vibration or rotation of the massager. The micro motor is usually selected according to the function and design of the massager to ensure an appropriate massage effect and user experience. The Chinese utility model patent, with the authorization publication number "CN 218569980 U", discloses a micro motor with a dust-proof component. Through the setting of the dust-proof component, when the rotor shaft runs, it can drive the transmission to run at the same time, so that it pulls the positioning ring upward through the winding spring body and then drives the positioning ring to move at the same time. When the device stops, the positioning ring can slide downward through the reset of the spring body and rotate along the rotor shaft at the same time, thereby driving the cleaning plate installed inside the two positioning plates to fit with the filter plate frame, so that a plurality of cleaning brush heads fixedly installed on its side clean the dust accumulated inside the filter plate frame, ensuring the heat dissipation effect while improving the dust-proof effect of the device. At the same time, when the device runs, the cleaning plate and the cleaning brush heads are separated from the protective cover, effectively reducing the wear of the cleaning brush heads and improving the service life of the dust-proof component.

[0003] However, for the micro motor on the massager, when using the massage device, not only dust falls on the heat dissipation net, but also some wire heads and the like fall on the heat dissipation net. If the cleaning brush heads in the above scheme are used for cleaning, the wire heads wound around the heat dissipation net are tightly wound with the heat dissipation net, and it is very difficult for the cleaning brush heads to clean the wire heads wound around the heat dissipation net, resulting in the blockage problem at its heat dissipation position. Summary of the Utility Model

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a micro motor for a massager with a dust-proof function, which can solve the problem that it is very difficult for the cleaning brush heads to clean the wire heads wound around the heat dissipation net, resulting in the blockage problem at its heat dissipation position.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A micro motor for a massager with a dust-proof function, including a micro motor housing, and a motor shaft is installed inside the micro motor housing;

[0006] A dust-proof and heat-dissipating component is arranged on the back of the micro motor housing. The dust-proof and heat-dissipating component includes a screw, a connecting piece II and a dust-proof and heat-dissipating net. The connecting piece II is welded on the dust-proof and heat-dissipating net. The surface of the screw is threadedly connected with the surface of the connecting piece II, and the surface of the screw is threadedly connected with the surface of the micro motor housing;

[0007] The anti-blocking component is arranged on the dust-proof and heat-dissipating net. The anti-blocking component includes a circular ring piece, two tool scrapers, a spring, a polygonal piece, a threaded column, a hole, a connecting piece one, a sharpening stone and a threaded hole. The threaded hole is opened on the dust-proof and heat-dissipating net, and the inner surface of the threaded hole is threadedly connected with the surface of the threaded column. The threaded column is welded to the polygonal piece. The circular ring piece is sleeved on the motor shaft, and both tool scrapers are welded to the circular ring piece. The surfaces of both tool scrapers are in contact with the surface of the dust-proof and heat-dissipating net.

[0008] Preferably, the connecting piece one is fixedly connected to the sharpening stone. The surface of the sharpening stone is in contact with the dust-proof and heat-dissipating net. One end of the sharpening stone is supported by the dust-proof and heat-dissipating net at a distance just enough to accommodate the tool scraper to rotate.

[0009] Preferably, the surface of the sharpening stone is in contact with the surface of the tool scraper. The hole is opened on the connecting piece one. The size of the hole is larger than that of the threaded column and smaller than that of the polygonal piece.

[0010] Preferably, a square hole is opened on the connecting piece one, and a square column is welded on the dust-proof and heat-dissipating net. The square column slides along the surface of the square hole.

[0011] Preferably, one end of the spring is welded to the dust-proof and heat-dissipating net, and the other end of the spring is welded to the connecting piece one.

[0012] Compared with the prior art, the beneficial effect of the present utility model is that: for the micro-motor of the massager with dust-proof function, by arranging two tool scrapers in the anti-blocking component, both tool scrapers are driven by its motor shaft to rotate. The rotation of the two tool scrapers can cut the thread ends wound on the dust-proof and heat-dissipating net. The cut thread ends move away from the dust-proof and heat-dissipating net along with the two tool scrapers, thus avoiding the phenomenon that the tightly wound thread ends cannot be cleaned, that is, ensuring the smooth air circulation of the dust-proof and heat-dissipating net.

[0023] Please refer to Figures 1-6 , the present utility model provides a technical solution: a micro-motor for a massager with a dust-proof function, including a micro-motor housing 1 (i.e., the micro-motor body), and a motor shaft 2 is installed inside the micro-motor housing 1;

[0024] The dust-proof and heat-dissipation component is arranged on the back of the micro-motor housing 1. The dust-proof and heat-dissipation component includes a screw 13, a second connecting piece 14 and a dust-proof and heat-dissipation net 15. The second connecting piece 14 is welded on the dust-proof and heat-dissipation net 15. The surface of the screw 13 is threadedly connected to the surface of the second connecting piece 14, and the surface of the screw 13 is threadedly connected to the surface of the micro-motor housing 1;

[0025] The anti-blocking component is arranged on the dust-proof and heat-dissipation net 15. The anti-blocking component includes a circular ring piece 3, two tool scraping plates 4, a spring 5, a polygonal piece 7, a threaded column 8, a hole 9, a first connecting piece 10, a sharpening stone 11 and a threaded hole 16. The threaded hole 16 is opened on the dust-proof and heat-dissipation net 15. The inner surface of the threaded hole 16 is threadedly connected to the surface of the threaded column 8. The threaded column 8 is welded to the polygonal piece 7. The circular ring piece 3 is sleeved on the motor shaft 2. Both of the two tool scraping plates 4 are welded on the circular ring piece 3. The surfaces of both of the two tool scraping plates 4 are in contact with the surface of the dust-proof and heat-dissipation net 15.

[0026] The first connecting piece 10 is fixedly connected to the sharpening stone 11. The surface of the sharpening stone 11 is in contact with the dust-proof and heat-dissipation net 15. One end of the sharpening stone 11 is supported by the dust-proof and heat-dissipation net 15 at a distance just enough to accommodate the tool scraping plate 4 for rotation.

[0027] The surface of the sharpening stone 11 is in contact with the surface of the tool scraping plate 4. The hole 9 is opened on the first connecting piece 10. The size of the hole 9 is larger than that of the threaded column 8 and smaller than that of the polygonal piece 7.

[0028] A square hole 12 is opened on the first connecting piece 10. A square column 6 is welded on the dust-proof and heat-dissipation net 15. The square column 6 slides along the surface of the square hole 12.

[0029] One end of the spring 5 is welded on the dust-proof and heat-dissipation net 15, and the other end of the spring 5 is welded on the first connecting piece 10.

[0030] When it is necessary to clean the entangled wire heads and dust on the surface of the dust-proof and heat-dissipation net 15;

[0031] First, start the micro-motor. The start of the micro-motor drives the motor shaft 2 to rotate. The rotation of the motor shaft 2 drives the two tool scraping plates 4 to rotate to clean the entangled wire heads and dust on the surface of the dust-proof and heat-dissipation net 15.

[0032] Secondly, the rotation of the two tool scraping plates 4 makes relative movement with the sharpening stone 11 to polish the surface of the tool scraping plates 4.

[0033] It should be noted that:

[0034] 1. The purpose of setting the spring 5 is that when the tool scraping plate 4 rotates and collides with the grinding stone 11, due to the presence of debris on the tool scraping plate 4, the size of the tool scraping plate 4 will increase. If the grinding stone 11 gets stuck, the tool scraping plate 4 colliding with the grinding stone 11 can easily cause the phenomenon that the tool scraping plate 4 cannot pass through the grinding stone 11. Therefore, a spring 5 is installed on the connecting piece 1. When the tool scraping plate 4 collides with the grinding stone 11, the elastic force of the spring 5 not only provides the extrusion force required for the frictional force between the tool scraping plate 4 and the grinding stone 11, but also can avoid the phenomenon that the tool scraping plate 4 with debris cannot pass through the grinding stone 11.

[0035] 2. The square column 6 and the square hole 12 are set to be square, so that the grinding stone 11 can only move back and forth, preventing the tool scraping plate 4 from rotating and colliding with the grinding stone 11 and driving the grinding stone 11 to rotate, that is, ensuring the stability of the grinding stone 11 when grinding the tool scraping plate 4.

[0036] By setting two tool scraping plates 4 in the anti-blocking component, both tool scraping plates 4 are driven by the motor shaft 2 to rotate. The rotation of the two tool scraping plates 4 can cut the wire heads wound on the dust-proof and heat-dissipating net 15. The cut wire heads move away from the dust-proof and heat-dissipating net 15 along with the two tool scraping plates 4, thus avoiding the phenomenon that the tightly wound wire heads cannot be cleaned, that is, ensuring the smooth air circulation of the dust-proof and heat-dissipating net 15.

[0037] By setting the two tool scraping plates 4 in the anti-blocking component to continuously grind with the grinding stone 11, the tool scraping plates 4 are continuously ground by the grinding stone 11, ensuring that they are sharp enough when cleaning the wire heads.

[0038] By setting the spring 5 in the anti-blocking component, the setting of the spring 5 avoids the problem of damage to the tool scraping plate 4 or the grinding stone 11 when the wire heads wound on the tool scraping plate 4 directly collide with the grinding stone 11, that is, ensuring the safety of the grinding stone 11 when grinding the tool scraping plate 4.

[0039] Working principle: When it is necessary to clean the wire heads and dust wound on the surface of the dust-proof and heat-dissipating net 15;

[0040] First, start the micro-motor. The start of the micro-motor drives the motor shaft 2 to rotate, and the motor shaft 2 drives the two tool scraping plates 4 to rotate to clean the wire heads and dust wound on the surface of the dust-proof and heat-dissipating net 15.

[0041] Secondly, the rotation of the two tool scraping plates 4 makes relative movement with the grinding stone 11 to grind the surface of the tool scraping plates 4.

[0042] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art.
