Description
- The present invention relates to a brush structure and a bristle structure thereof, and more particularly, to the brush structure and the bristle structure thereof providing a highly effective cleaning ability.
- There are many different types of brushes in the present market, most of the brushes are specified by their cleaning ability, the cleaning ability is distinguished by the structure of the bristles, and hence some of the countries have revealed related patents, for example, the following patents of the Republic of China (Taiwan): 269780, 272398, 312615, 319683, 344657, 374701, 388708, 414035, 430550, 440439, 1230044 and M281505, and U.S. Pat. Nos. 4,167,794, 4,317,463, 4,471,505, 5,678,275, 5,926,897, 5,987,691, 6,138,314, 6,276,021, 6,643,886, 6,851,153, 6,886,207, D483,950 and D487,350 . . . etc.
- In the prior art, the U.S. Pat. No. 5,678,275, “Toothbrush with bristles having intermediate roughened portion”, discloses a slightly similar structure as the invention described here. The U.S. Pat. No. 5,678,275 reveals a kind of the structure of the toothbrush which is consisted of a plurality of bristles and each of the bristles is consisted of a stabilizing post which is rigidly attached to the head portion, a plurality of roughened portions on the post, and a smooth tip at the free end of the post. The roughened portions are evenly placed on the stabilizing post and each roughened portion consists of a plurality of grooves. In general the free ends of the bristles are where get touched with the cleaned objects, and thereby the free ends of the bristles should have a strong cleaning ability. In the U.S. Pat. No. 5,678,275, the free end of each bristle is a short cylinder with a smooth tip; hence this structure does not provide an obvious cleaning ability.
- In addition strong scraping boards are required to clean the crud, the scraping boards in the structure of the bristles provided by the U.S. Pat. No. 5,678,275 are thin and weak, and thereby the cleaning ability of the bristles is not strong. Furthermore some small pieces of crud will be stuck in the fillisters because the fillisters of the bristles are very narrow and deep, and thereof the crud stuck in the fillisters is very difficult to be cleaned or washed away.
- The complicated structure of the roughened portions of the bristles of the U.S. Pat. No. 5,678,275 has a high cost. The main objective of the present invention is to provide a brush structure and a bristle structure thereof having a highly effective cleaning ability and a low cost.
- One of the objectives of the present invention is to provide a brush structure and a bristle structure thereof to scrape and take away the crud from the surface of the cleaned object with a highly effective cleaning ability.
- One of the objectives of the present invention is to provide a brush structure and a bristle structure thereof to clean or wash away the crud jammed on the bristles easily.
- One of the objectives of the present invention is to provide a brush structure and a bristle structure which can't easily harm the surface of the cleaned object.
- The present invention provides a brush structure and a bristle structure thereof with highly effective cleaning ability. The brush structure includes a brush body and a bristle structure. The bristle structure is set up on the brush body and includes a plurality of bristles. Each bristle has a cleaning structure set up at the free end of the bristle. The cleaning structure includes a plurality of cleaning units. Each cleaning unit has a near end and a far end relative to the position of the brush body, and the diameter of the near end is larger than the diameter of the far end.
