Abstract
Description
Technical Field
[0001] This utility model relates to the technical field, and in particular to a novel LTCC filter. Background Technology
[0002] LTCC filters are filter products manufactured using LTCC (Low Temperature Co-fired Ceramics) technology. Their principle is similar to LC filters, consisting of inductors and capacitors. The difference lies in that the inductors and capacitors are implemented within the ceramic layer using a multi-layer printing process. LTCC is an abbreviation for Low Temperature Co-fired Ceramics. By incorporating glass components into the ceramic material, LTCC can lower the firing temperature to around 900°C, allowing the use of copper and silver, which have lower conductor resistance, in the internal wiring, resulting in considerably high operational reliability.
[0003] Existing LTCC filters, while significantly improving operational stability due to their ceramic substrates, are susceptible to damage during transport due to the fragility of ceramic materials caused by shaking and impacts. Furthermore, in high-humidity environments such as the rainy season, although the waste heat generated during operation raises the saturation threshold of internal gases, thus reducing the impact on the equipment, condensation may occur when not in use due to temperature changes. This can not only cause corrosion of electronic components on the substrate but also potentially lead to short circuits upon restarting, indicating room for further improvement. Utility Model Content

A filter screen is fixedly connected to the bottom of the drying box, and a water receiving tank is fixedly connected to the bottom of the filter screen. An indicator is fixedly connected to the outer side of the filter housing at a position corresponding to the water receiving tank.

[0008] According to the novel LTCC filter, the buffer base is a pneumatic damper with an internal spring, and the central rod of the rubber support is fixedly connected to the internal piston of the pneumatic damper.
[0009] According to the novel LTCC filter, the inner side of the drying box is provided with a water-resistant membrane, and the water-resistant membrane is a commercially available waterproof and breathable membrane.
[0010] According to the novel LTCC filter, the ends of the two communicating vessels away from the indicator pass through the filter housing and are fixedly connected to the top and bottom of the water receiving tank, respectively.
[0011] According to the novel LTCC filter, a water outlet pipe is fixedly connected to one side of the bottom of the water receiving tank, and a water outlet cover is provided at the water outlet pipe.
