Embodiment Construction
[0039] Now in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.
[0040] see figure 1 , A cavity filter, comprising a cavity and a cover plate, a signal channel is provided in the space formed by the cavity body and the cover plate, and a liquid inlet 10 and a liquid outlet 20 are respectively provided at both ends of the signal channel. Preferably, the liquid outlet is arranged on the cover plate of the cavity filter, and the liquid inlet is arranged on the cover plate or the side wall of the cavity. The liquid inlet and outlet are not directly facing the tap of the filter, so as to prevent the high-speed fluid from affecting the position of the tap. The two ends of different signal channels to be cleaned on the same filter are provided with corresponding liquid inlets and liquid outlets. When the filter is not cleaned, its inlet and outlet are closed.
[0041] After the filter is assembled and debug...

The invention relates to a cavity filter and a cleaning method thereof. The cavity filter comprises a cavity and a cover plate, a space formed by the cavity and the cover plate is provided with a signal channel, and two opposite ends of the signal channel of the cavity filter are provided with a liquid inlet and a liquid outlet. The cleaning method comprises the steps that a mixed medium of pulse air and cleaning liquid is injected into the cavity filter from the liquid inlet of the filter to be washed, the mixed medium forms jet flow and instant high-frequency shock waves to impact the inner cavity of the cavity filter, dirt and metal chips flow out from the liquid outlet through the signal channel of the filter along with gas-liquid flow, and then compressed air is adopted to blow-dry the interior of the cavity. The inside of the filter can be cleaned under the condition that the cover plate is not disassembled, so that re-disassembly and re-assembly are avoided, manpower and material resources are saved, and meanwhile, the product performance is improved.
Description
technical field [0001] The invention relates to cleaning of electronic devices, in particular to a cavity filter and a cleaning method thereof. Background technique [0002] During the production process of the cavity filter, it is necessary to assemble components such as connectors, resonant rods, taps, connecting rods, flying rods, flying rod holders, low-pass and low-pass bushings on the cavity, and then screw them A cover plate is secured to the cavity. Or put tin on the ribs of the cavity or the cover plate, and then heat to weld the cover plate and the cavity together to form a resonant filter signal channel to realize product functions. Debug and test the filter after assembly to ensure its technical specifications. [0003] Foreign matter such as metal chips (such as silver chips, aluminum chips, metal wires, etc.), rosin, and surface dirt generated during the above-mentioned assembly, welding, and debugging processes will remain in the cavity of the filter, seriou...
