[0020] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0021] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present application and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.
[0022] The following is combined with Figure 1-2 This application is further described in detail.
[0023] Reference Figure 1-2, an oil filter comprises: a filter body, a filter cavity is arranged in the filter body, an oil inlet port 1 which penetrates the filter cavity is arranged at one end of the filter body, a filter part for filtering impurities and foreign matters is arranged at the other end of the filter body (the filter part is adjacent to the filter cavity), a fixing piece for fixing the filter body on the brake oil reservoir is arranged on the outside of the filter body, and the filter body, the filter part and the fixing piece are integrally injection molded. In this way, when in use, the filter body is placed on the oil filling port of the brake oil reservoir through the fixing piece, and the brake oil is injected into the filter cavity from the oil inlet port 1, filtered through the filter part, and finally the clean brake oil enters the brake oil reservoir. Since the filter body, the filter part and the fixing piece are integrally injection molded, there is no need to make a nylon mesh and there is no need to place the nylon mesh in the mold, which improves production efficiency, reduces product defects, and ensures product function.
[0024] Reference Figure 1-2 In order to install the filter, the filter body includes a ring plate 4 arranged on the ring side of the oil inlet port 1. The filter body is clamped at the injection port of the brake oil reservoir through the ring plate 4 for easy operation. In order to facilitate the smooth injection of oil, a plurality of inwardly concave air holes 41 are arranged on the outer side of the ring plate 4. When the oil is injected, the gas in the brake oil reservoir is discharged through the air holes 41.
[0025] Reference Figure 1-2 The fixing part includes a plurality of elastic buckles 3, which are arranged on the ring side of the filter body. The filter body is clamped at the injection port of the brake oil reservoir through the plurality of elastic buckles 3, wherein the specific shape of the elastic buckle 3 is arc-shaped, the opening end of the elastic buckle 3 faces one side of the filter body, one end of the elastic buckle 3 is connected to the filter body, and the two ends of the elastic buckle 3 point to the filter part and the oil inlet 1 respectively. In this way, when the filter body is installed, the injection port of the brake oil reservoir squeezes the elastic buckle 3, so that the opening of the elastic buckle 3 becomes larger, providing elastic force for the filter body.
[0026] Reference Figure 1-2 In order to improve the filtering efficiency, the filter part includes a plurality of first filter parts 2 and a plurality of second filter parts 5. The plurality of first filter parts 2 are arranged at the bottom of the filter cavity. The first filter part 2 is provided with a plurality of first filter holes which are connected with the filter cavity. The plurality of second filter parts 5 are arranged on the ring side of the filter cavity. The second filter part 5 is provided with a plurality of second filter holes which are connected with the filter cavity. In this way, the filtering area is increased and the filtering efficiency is improved. In order to improve the strength of the filter part and to increase the service life of the oil filter, the plurality of first filter parts 2 are not connected, and the plurality of second filter parts 5 are not connected, so that there is an unopened part between adjacent first filter parts 2 and adjacent second filter parts 5, thereby improving the strength of the filter part.
[0027] Further optimized is that the filter body, the filter part and the fixing part are made of polypropylene.
[0028] In summary: when in use, the filter body is placed on the oil filling port of the brake oil reservoir through the fixing parts, the brake oil is injected into the filter cavity from the oil inlet port 1, filtered through the filter part, and finally the clean brake oil enters the brake oil reservoir. Since the filter body, the filter part and the fixing parts are integrally injection molded, there is no need to make a nylon mesh and there is no need to place the nylon mesh in the mold, which improves production efficiency, reduces product defects, and ensures the function of the product.
[0029] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
