Other common ones include telephone voice switches, fiber optic switches, etc., and the signal enhancement and filtering device of the switch is mainly a filter.

[0003] According to a filter disclosed in Chinese Patent No. CN 220774701 U, it includes a cavity, a resonant member and an elastic sleeve. The cavity has a mounting hole and a first limiting step; the first limiting step abuts against the resonant member to limit the resonant member from being further inserted into the mounting hole along the depth direction of the mounting hole; one of the hole wall of the mounting hole and the resonant member is used for socket joint with the elastic sleeve, and the other of the hole wall of the mounting hole and the resonant member has a second limiting step, and the second limiting step abuts against the elastic sleeve to limit the resonant member from leaving the mounting hole along the depth direction of the mounting hole. In this way, the mounting hole, the first limiting step, the second limiting step and the elastic sleeve fix the resonant member in the cavity, and the cavity does not need to be machined with threaded holes, solving the technical problems of low processing efficiency and high processing cost of the existing filter cavity, thereby improving the production efficiency of the cavity and reducing the processing cost of the cavity.

[0004] The filter in the prior art solves the technical problems of low processing efficiency and high processing cost of the existing filter cavity, but there will be the following problems in the actual use process; the existing filter cannot automatically clean the inductor coil inside regularly, and when dust accumulates on the coil surface for a long time, it will affect filtering, so a switch signal enhancement and filtering device is needed to solve the above problems. Summary of the Utility Model

The cleaning cover is provided with multiple groups of cleaning structures. The cleaning structure is composed of scraping blades and brush plates. Sandpaper is adhered to the surface of the scraping blades, and the bristles on the surface of the brush plate are soft brushes.

However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present utility model.

[0024] The following describes the specific embodiments of the present utility model with reference to the drawings. Specific embodiment one:

[0026] Refer to Figures 1-5 , a switch signal enhancement and filtering device, including a chassis 1, a core column 3 is installed in the middle of the chassis 1, an electromagnetic coil 4 is wound around the outside of the core column 3, a cleaning cover 2 is installed near the top of the core column 3 inside the chassis 1, the shape of the cleaning cover 2 is arc-shaped, the bottom of the cleaning cover 2 is attached to the surface of the core column 3, a dust suction cover 5 is clamped inside the chassis 1 near the bottom of the core column 3, and a support leg 8 is screwed to the bottom of the chassis 1.

[0027] This device provides a filter, and the surface of the core column 3 and the electromagnetic coil 4 can be wiped and cleaned through the cleaning cover 2.

[0028] Scrapers 10 are arranged in a rectangular array at the bottom of the cleaning cover 2, a brush plate 11 is clamped between adjacent scrapers 10, and brush bristles 12 are provided at the bottom of the brush plate 11.

[0029] The cleaning cover 2 is provided with multiple groups of cleaning structures, which are composed of scrapers 10 and brush plates 11. Sandpaper is adhered to the surface of the scrapers 10, and the brush bristles 12 on the surface of the brush plates 11 are soft brushes.

[0030] On one side outside the chassis 1, a transfer track 6 is provided. Near the middle of the transfer track 6 on one side of the chassis 1, a rotary drive assembly 9 is installed. One end of the rotary drive assembly 9 is drivingly connected to a connecting handle 7, and the shape of the connecting handle 7 is L-shaped.

[0031] The end of the connecting handle 7 is connected to one side of the cleaning cover 2.

[0032] The rotary drive assembly 9 is a motor structure in the prior art. The connecting handle 7 can be understood as the output end of the motor structure. When the motor structure drives the connecting handle 7 to rotate, it will rotate along the transfer track 6. Specific Embodiment Two:

[0034] Refer to Figures 1-5 , a flip door 16 is snap-connected to the front of the chassis 1. A detection unit 17 is installed on the back of the flip door 16. A dust content detection sensor 18 is electrically connected to the front of the detection unit 17.

[0035] A command transmitter 19 is electrically connected to the bottom of the detection unit 17.

[0036] In the middle of the top of the dust suction hood 5, a suction device 13 is installed. The top of the suction device 13 is connected to a dust suction head 14 through a pipeline. One side of the dust suction hood 5 is flange-connected to a dust guide pipe 15.

[0037] The detection principle of the dust content detection sensor 18 is as follows: When particles and molecules are irradiated by light, light scattering will occur. At the same time, part of the energy of the irradiated light is also absorbed. When a beam of parallel monochromatic light is incident on the measured particle field, it will be affected by scattering and absorption around the particles, and the light intensity will be attenuated. In this way, the relative attenuation rate of the incident light passing through the measured concentration field can be obtained. The size of the relative attenuation rate can basically linearly reflect the relative concentration of dust in the measured field. The size of the light intensity is proportional to the strength of the electrical signal after photoelectric conversion. By measuring the electrical signal, the relative attenuation rate can be obtained. The dust content detection sensor 18 selected here can detect dust particles above 1 micron.

[0038] After the dust content detection sensor 18 detects the dust content, it will transmit the value to the detection unit 17. The detection unit 17 is a small computing computer and will compare the detected value with the dust content limit value. Here, the dust content limit value refers to whether it reaches the range that needs to be cleaned. When the limit value is reached, it will be wirelessly transmitted to the rotary drive assembly 9 through the command transmitter 19. A receiving chip is implanted in the rotary drive assembly 9. After receiving the signal through the receiving chip, it will start to drive the connecting handle 7 to rotate. After the connecting handle 7 rotates, it will drive the cleaning cover 2 to rotate in close contact with the surface of the magnetic core column 3. During the rotation process, the scraping blade 10 will scrape off hard impurities, while the brush plate 11 and the bristles 12 will wipe the ordinary dust on the surface, from attach Figure 3It can be seen that the cleaning structure on the cleaning cover 2 is arranged obliquely, and is close in shape to the gap between the electromagnetic coil 4, so that the cleaning structure can also effectively clean the gap.

[0039] In summary:

[0040] 1. This equipment provides a filter. The surface of the magnetic core column 3 and the electromagnetic coil 4 can be wiped and cleaned through the cleaning cover 2. The cleaning cover 2 is provided with multiple groups of cleaning structures. The cleaning structure is composed of a scraper 10 and a brush plate 11. The surface of the scraper 10 is bonded with sandpaper, and the bristles 12 on the surface of the brush plate 11 are soft brushes. The rotary drive assembly 9 is a motor structure in the prior art. The handle 7 can be understood as the output end of the motor structure. When the motor structure drives the handle 7 to rotate, it will rotate along the turn track 6.

[0041] 2. The detection principle of the dust content detection sensor 18 is as follows: Particles and molecules scatter light when exposed to light, and at the same time, they absorb some of the energy of the irradiated light. When a beam of parallel monochromatic light is incident on the particle field to be measured, it is affected by scattering and absorption around the particles, and the light intensity is attenuated. This allows the relative attenuation rate of the incident light passing through the concentration field to be measured to be determined. The magnitude of the relative attenuation rate generally linearly reflects the relative dust concentration in the test field. The light intensity is directly proportional to the strength of the electrical signal generated by photoelectric conversion. By measuring the electrical signal, the relative attenuation rate can be calculated. The dust content detection sensor 18 selected here can detect dust particles larger than 1 micron.

[0042] After detecting the dust content, the dust content detection sensor 18 will transmit the value to the detection unit 17. The detection unit 17 is a small computer that will compare the detected value with the dust content limit value. The dust content limit value here refers to whether it has reached the range that needs to be cleaned. When the limit value is reached, it will be wirelessly transmitted to the rotation drive component 9 through the instruction transmitter 19. The rotation drive component 9 is implanted with a receiving chip. After receiving the signal through the receiving chip, it will start to drive the handle 7 to rotate. After the handle 7 rotates, it will carry the cleaning cover 2 to the surface of the magnetic core column 3 and rotate. During the rotation process, the scraper 10 will scrape off the hard impurities, and the brush plate 11 and the bristles 12 will wipe the ordinary dust on the surface, from the attached Figure 3 It can be seen that the cleaning structure on the cleaning cover 2 is arranged obliquely, and is close in shape to the gap between the electromagnetic coil 4, so that the cleaning structure can also effectively clean the gap.
