Miniaturized double-band-pass dielectric filter

Abstract

The invention relates to the technical field of filters, and discloses a miniaturized dual-band-pass dielectric filter which comprises a filter body, wherein connecting electronic elements are arranged on the left side and the right side of the filter body, mounting pieces are fixedly connected to the front side and the rear side of the filter body, an air inlet hole is formed in the upper surfaceof the filter body, a filter screen is fixedly connected to the interior of the air inlet hole, a cleaning ring is fixedly connected to the upper surface of the filter body, the cleaning ring is conical and hollow, a cooling fan is arranged on the bottom surface of the interior of the filter body, and a temperature sensor is fixedly connected to the bottom surface of the interior of the filter body. According to the high-performance dual-channel filter, a heat dissipation ball is rotationally connected to the interior of the cleaning ring, so that when the heat dissipation ball rotates, the inner wall of the cleaning ring scrapes the outer surface of the heat dissipation ball, dust adsorbed by the heat dissipation ball can be scraped off, and the phenomenon that the heat dissipation ballcarries the dust to enter the filter body is avoided.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a miniaturized double-band-pass dielectric filter. Background technique [0002] The filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter out the frequency points of a specific frequency in the power line or frequencies other than this frequency point, obtain a power signal of a specific frequency, or eliminate a specific frequency. The power signal after frequency can filter out interference noise or perform spectrum analysis by using the frequency selection function of the filter. [0003] The power consumption of the filter is relatively high, and a large amount of heat will be generated during the working process. Most of the existing filters generally use cooling vents to dissipate heat, and the cooling effect is not very good. Demand, and the heat dissipation port is easy to get dust, so it is difficult to clean. C...
