Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a color wheel, and more particularly to a color wheel that prevents oil and gas from escaping. [Prior Art] The design of electronic products tends to be light, thin, short, and small. In terms of displays, the big screen is the current trend. In order to meet the above requirements, it is bound to shrink the mainframe. Therefore, with current display technology, such a demand can only be achieved with a plasma screen and a projection system. However, due to the high price of the plasma screen, the projection system has become the primary choice for current consumers. There are three types of projection systems available today, which can be divided into LCD, LcoS and DLP. Among them, there are two types of simplification systems, Lc〇s and DLP. Both systems use the color wheel (c〇l〇r wheel). Color separation mechanism. The following is an example of a DLP system. DLP projectors use digital control and operate with reflected light principles. After the light source is collected and focused by a lens, it passes through a color filter of a red-green color filter and is projected onto a digital micro-middle device (DMD). In this technology, a digital micromirror wafer is used in place of a conventional liquid crystal projector, and the liquid crystal panel of the image is presented. Since the digital micromirror wafer has a plurality of tiny movable lenses, the driving electrodes are used to control the tilt angle and the deflection time of the movable lens, and the error is projected from the lens by the reflection direction of the switching light. 1263068 a shows that in the shadow system 1, since the color wheel 11 must be rotated high, the motor 112 that drives the color filter and the light sheet 111 rotates generally has an operating temperature of the pole face. However, due to the shaft cover of the motor 112! (2) Upper: : The rivet of the rotating shaft 1122, so that the oil and gas inside the motor 112 will pass through: , the imprint spreads outward, and adheres to the color filter and the light sheet lu, because the white mist-like oil and gas adheres to the color filter. The film lu affects the light travel path, and the shirt sounds to the quality of the projection system 1. The inventor 爰 because of this in the spirit of active invention, thinking about a "color wheel" that can solve the above problems, after several research and experiments to complete the invention of this tribute to the world. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a color wheel that prevents oil and gas from escaping. In order to achieve the above object, the color wheel according to the present invention comprises a motor, a cover member and a color calender, wherein the motor is composed of a core cover and a motor body. The shaft cover is disposed on the opposite side of the cover of the motor body and the motor body has a surface, and the shaft cover and the motor system rotate along the central axis; the cover member is sleeved on the cover; the color filter is The ring is provided on the covering element. In order to achieve the above object, a color wheel according to the present invention comprises a motor, an annular cover sheet and a color filter. The motor is composed of a shaft cover and a motor body. The motor system has a central axis. The shaft cover is made up of 1263068 coils (not shown). When the coil is energized, the silicon steel sheet generates a magnetic force and a magnetic field, and the magnetic field I changes in an orderly manner by the positive and negative energies of the current, that is, a rotating magnetic field, so that the magnet ring and the rotating magnetic field act to form a rotation. As shown in FIG. 2 and FIG. 3, the color wheel 2 of the present embodiment further includes an absorbing member 24, and the absorbing member 24 is coated on the surface 2111 of the shaft cover 211. In this embodiment, the absorbing element 24 is capable of absorbing the dissipated oil and gas. In addition, the absorbing element 24 also reduces the transmission of noise and the vibration of the absorbing motor. In addition, please refer to FIG. 2 again, the cover member 22 can be extended to the first surface 231 of the color filter and the light sheet 23, and the first surface 231 is adjacent to the shaft cover 21, and then refer to FIG. The cover member 22 is extendable to a second surface 232 of the color filter 23, and the second surface 232 is disposed opposite the first surface 231. As shown in Figures 4 and 5, the cover member 22 can also cover the surface 2111 of the hub cover 211. Wherein, a sealing space can be formed between the covering member 22 and the surface 2111 of the shaft cover 211. Here, the absorbing member 24 can be located in a sealed space. Here, as shown in FIG. 4, the covering member 22 can also be extended to the first surface 231 of the color filter 23. Alternatively, as shown in FIG. 5, the cover member 22 can also be extended to the second surface 232 of the color filter 23. Referring to Figures 2 and 3, the color filter 23 is an annular filter formed of three color filters of red, green and blue. Another 1263068^ The color filter 33 of the present embodiment is a circular filter. Here, the heart color filter 33 is a circular filter formed of a three-color fan-shaped filter of red, green, and blue. In addition, the color filter 33 may also be a circular filter formed by a plurality of blocks of red, green, and blue colors, or may be a red, green, and blue color plus a white transparent area. A circular filter formed by a plurality of ghosts of a block. Of course, the color filter 33 may also be a film formed by forming a plurality of blocks of red, green, and blue colors on a circular transparent plate. '
