Description

Technical Field

[0001] The utility model relates to the technical field of filters, and specifically relates to a micro high-frequency filter. Background Art

[0002] A filter is an electronic or mechanical device whose basic function is to allow signals of certain frequencies to pass through while suppressing or blocking signals of other frequencies. In the field of signal processing, a filter is an important tool for signal screening and purification. In electronics, filters can be implemented based on different physical principles. For example, a passive filter can be designed using a combination of capacitors, inductors, and resistors, or an active filter can be implemented through electronic devices such as operational amplifiers. A passive filter does not contain amplification elements and its function is limited to filtering signals; while an active filter has an internal amplifier and can amplify and filter signals.

[0003] The patent document with the application number CN201921640039.4 discloses a filter, which includes a housing and at least one filter body. At least one mounting hole is provided on one side of the housing, and at least one fixing hole is provided on the opposite side of the housing. The filter body is provided with a fixing part. The filter body is inserted into the housing through the mounting hole, and the filter body is connected to the fixing hole of the housing through the fixing part. A connection terminal is provided at each end of the filter. The connection terminals at both ends of the filter body extend to the outside of the housing. The beneficial effect of the utility model is that it provides a filter with a housing, which not only ensures the safety and reliability of the filter but also facilitates the installation of the filter. The filter is small in size and compact in structure, greatly saving the installation space. Based on the retrieval of the above patent and the combination with the filters in the prior art, it is found that during the application of the filter, due to the heat accumulation generated by the operation of internal components during the working process of the filter, the temperature of the filter often rises. As the temperature rises, the electrical characteristics of electronic components may change, such as an increase in resistance, resulting in a decline in the filtering effect. Continuous high temperature may cause thermal stress on the structural materials of the filter, affecting its mechanical stability, and even may lead to the failure of components.

At the lower end of the filter body 2, the snap slider 306 is fixedly installed. On the outside of the snap slider 306, there is a first installation block 307. The first installation block 307 is fixedly installed at the upper end of the mounting plate 1; the wind guiding pipe body 301 and the flow guiding pipe body 302 enable the air flow to be smoothly guided into the filter. The heat dissipation air grooves 303 guide the air flow to be evenly dispersed into the filter, realizing uniform temperature distribution throughout the filter body 2.

[0027] The working principle of the present utility model is as follows: This filter is additionally provided with a diversion mechanism 3 and a blowing mechanism 4. Before using this filter, it is necessary to pre-install the diversion mechanism 3 and the blowing mechanism 4 on the filter body 2, connect the blower body 402 to electricity and connect it to the control terminal. When using this filter, after the filter body 2 is powered on and enabled, the diversion mechanism 3 and the blowing mechanism 4 are enabled accordingly. The blower body 402 inside the blowing mechanism 4 sends air into the blowing duct 401. The air body flows through the blowing duct 401 and reaches the air guide duct body 301 of the diversion mechanism 3. The air body impacts on the air blocking plate body 304. Under the influence of the air blocking plate body 304, the air body will be conveyed downward through the heat dissipation air slots 303 to the internal parts of the filter body 2, which can effectively reduce the temperature of the internal parts of the filter body 2, thereby achieving the heat dissipation effect. After the cooling operation, the air body will be discharged outside through the heat dissipation slots 305 to achieve the heat dissipation effect. To sum up, the blowing mechanism 4 adopts the method of electric blowing, and the diversion mechanism 3 adopts the method of diversion. The diversion mechanism 3 and the blowing mechanism 4 complement each other to form a heat dissipation and diversion structure. The blowing mechanism 4 can blow air into the diversion mechanism 3. The air flow is conducted to the air guide duct body 302 of the diversion mechanism 3 and is introduced into the filter body 2 through the heat dissipation air slots 303. The air blocking plate body 304 can guide the air flow to the parts of the filter body 2, thereby achieving the cooling and heat dissipation effect. The excess hot air is then discharged outside through the heat dissipation slots 305.
