Description

Technical Field

[0001] This utility model relates to the field of filter technology, and more specifically to an integrated filter. Background Technology

[0002] Existing filters are generally filter circuits composed of capacitors, inductors, and resistors. Filters allow specific frequency components of a signal to pass through while significantly attenuating other frequency components. Common filter types include LC filters (composed of discrete capacitors and inductors), dielectric filters (composed of a dielectric block formed from a high-dielectric-constant material, and a metal film layer designed to form the filter circuit structure on the dielectric block), and cavity filters (composed of a metal structure). For example, there is an integrated filter with prior art publication number CN221328083U.

[0003] However, the existing technologies mentioned above still have the following problems when in use: the components inside traditional integrated filters will continuously generate heat when processing signals. Since the components are located inside the filter housing, the staff cannot quickly know the filter temperature and usage status. Therefore, when the filter temperature is too high or abnormal noise is generated, the staff cannot take timely measures, which will cause the filter to operate in an abnormal state for a long time. This will not only accelerate the aging of internal components and greatly shorten their service life, but may also cause a chain of failures, resulting in problems such as signal transmission interruption and data loss. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides an integrated filter that integrates a filter component, a temperature sensor, and a sound sensor. The filter component is used to process signals, while the temperature sensor and the sound sensor respectively implement temperature and noise monitoring functions, so as to promptly detect potential problems and take corresponding measures to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated filter, comprising a housing and a filtering component disposed within the housing, the filtering component comprising a circuit board, a capacitor, an inductor, and a resistor connected to the top of the circuit board, the housing comprising a top cover and a base, a mounting bracket connected to the inner wall of the top of the top cover, a temperature sensor and a sound sensor connected to the inner wall of the top of the mounting bracket, slots being machined on both the front and rear sides of the top of the circuit board, the bottom end of the mounting bracket being inserted into the slots and detachably connected to the circuit board, heat dissipation holes being machined on the bottom of the base and on both sides of the top of the top cover, and a ventilation slot communicating with the heat dissipation holes being machined on the bottom of the base.

[0006] In a preferred embodiment, the monitoring device includes a temperature sensor and a sound sensor, which are mounted on the inner wall of the top of the mounting bracket.

[0007] In a preferred embodiment, each heat dissipation hole is detachably connected to a filter screen, and a heat dissipation fan is detachably connected to the heat dissipation hole located in the base. There are two heat dissipation fans, and both heat dissipation fans are located above the filter screen.

[0008] In a preferred embodiment, the inner wall of the top of the top cover is machined with a mounting groove adapted to the mounting bracket, the mounting bracket being inserted into the mounting groove and detachably connected to the top cover.

[0009] In a preferred embodiment, a heightening plate is hinged to the ventilation slots on both sides of the bottom end of the base, and the heightening plate is located outside the filter screen.

[0010] In a preferred embodiment, wiring terminals are fixedly provided on both sides of the circuit board, and mounting openings are machined on both sides of the top cover, with the wiring terminals located inside the mounting openings.

[0011] In a preferred embodiment, positioning plates 1 are fixedly provided on both the front and rear sides of the top of the base, and positioning plates 2 are fixedly provided on both sides of the top of the base. The two positioning plates 1 are respectively in contact with the inner walls of the front and rear sides of the top cover and are detachably connected to the top cover. The top of the two positioning plates 1 are in contact with the inner wall of the top of the top cover, and the two positioning plates 2 are respectively inserted into the two mounting holes and in contact with the bottom of the wiring terminal.

[0012] The technical effects and advantages of this utility model are as follows:

The filter component is used to process signals, while the temperature sensor and the sound sensor respectively realize temperature and noise monitoring functions. When the internal temperature of the filter is detected to be too hot, the cooling fan blows air into the filter to accelerate heat dissipation and ensure stable operation of the equipment. At the same time, the staff can accurately judge the working status of the filter based on the sound information so as to promptly discover potential problems and take corresponding measures.

[0014] 2. The circuit board is mounted on the top cover using a mounting bracket, and the top cover and base are detachably connected.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Refer to the instruction manual appendix Figures 1-6 This utility model provides an integrated filter, including a housing 1 and a filter component 2 disposed inside the housing 1. The filter component 2 includes a circuit board 201. A capacitor 202, an inductor 203 and a resistor 204 are connected to the top of the circuit board 201. Terminals 205 are fixedly provided on both sides of the circuit board 201. The housing 1 includes a top cover 101 and a base 102. The top cover 101 has an inverted U-shaped structure, that is, the top cover 101 includes a top plate (not shown) and two side plates (not shown) connected to the two sides of the top plate. The bottom of the two side plates is connected to the base 102. Mounting openings 12 are machined on both sides of the top cover 101, and the terminal 205 is disposed inside the mounting openings 12.

[0027] A mounting bracket 3 is connected to the inner wall of the top of the top cover 101. A monitoring device 4 is connected to the inner wall of the top of the mounting bracket 3. Specifically, the monitoring device 4 includes a temperature sensor 401 and a sound sensor 402. The temperature sensor 401 is a DS18B20. This temperature sensor 401 uses digital signal transmission and has good anti-interference performance, thus enabling stable temperature detection. The sound sensor 402 is a KY-038. This sound sensor 402 has a modular design, with analog and digital outputs and adjustable sensitivity. It can be used for sound detection in this utility model, and is therefore suitable for monitoring sound within the filter. The temperature sensor 401 and the sound sensor 402 are mounted on the inner wall of the top of the mounting bracket 3.

[0028] The circuit board 201 has slots 5 on both the front and rear sides of its top. The bottom of the mounting bracket 3 is inserted into the slots 5 and is detachably connected to the circuit board 201. The bottom of the base 102 and the top of the top cover 101 have heat dissipation holes 6 on both sides. The bottom of the base 102 has ventilation slots 7 that communicate with the heat dissipation holes 6.

[0029] Each heat dissipation hole 6 can be detachably connected to a filter screen 8, and a cooling fan 9 can be detachably connected to the heat dissipation hole 6 located in the base 102. There are two cooling fans 9, and both cooling fans 9 are located above the filter screen 8. The cooling effect of the filter can be improved by the two cooling fans 9.

[0030] When the filter is connected to a power source, it integrates a capacitor 202, an inductor 203, a resistor 204, a temperature sensor 401, and a sound sensor 402. The capacitor 202, inductor 203, and resistor 204 form a filtering circuit that can effectively filter out specific frequencies or frequencies other than those in the power line to obtain a power signal of a specific frequency. At the same time, the temperature sensor 401 and the sound sensor 402 monitor the temperature and sound inside the filter. If the temperature is detected to be too high, the cooling fan 9 in the heat dissipation hole 6 blows air into the filter to dissipate heat. By judging the sound detected by the sound sensor 402, the operator can understand the working status of the filter.

[0031] Refer to the instruction manual appendix Figure 2 , Figure 5 and 6To facilitate quick installation of the mounting bracket 3 by staff, a mounting groove 10 adapted to the mounting bracket 3 is machined on the inner wall of the top of the top cover 101. The mounting bracket 3 is inserted into the mounting groove 10 and detachably connected to the top cover 101 by bolts. Positioning plates 13 are fixedly provided on both the front and rear sides of the top of the base 102, and positioning plates 14 are fixedly provided on both sides of the top of the base 102. The two positioning plates 13 contact the inner walls of the front and rear sides of the top cover 101 and are detachably connected to the top cover 101 by bolts. The tops of the two positioning plates 13 are in contact with the inner wall of the top of the top of the top cover 101. The two positioning plates 14 are inserted into the two mounting ports 12 and contact the bottom of the wiring terminal 205.

[0032] The filter assembly 2, temperature sensor 401, and sound sensor 402 are supported by the mounting bracket 3 and circuit board 201. After the staff separates the top cover 101 from the base 102, the mounting bracket 3 can be removed to disassemble and repair the filter assembly 2, temperature sensor 401, and sound sensor 402. The operation is simple and maintenance is more convenient.

[0033] like Figures 1-3 As shown, each of the ventilation slots 7 on both sides of the bottom of the base 102 is hinged with a riser plate 11, which is located outside the filter screen 8. The operator can pull the riser plate 11 to rotate it to a vertical position and fix it in place with bolts. This raises the base 102, increasing the airflow at the bottom of the base 102 and thus improving heat dissipation.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
