The control platform area 31 includes various circuit elements, a main circuit board, and a circuit control board, which are mainly an Internet of Things control platform and an active noise reduction main control platform. , Adjust the air volume, timing, automatic working mode, sleep mode, auxiliary heating mode, active noise reduction mode; you can also check the real-time PM2.5 value and noise value of the indoor air on the mobile phone; the filter element replacement can be automatically prompted.

The air inlet purification area 32 is mainly composed of a primary filter element 320 , a medium effect filter element 321 , a high efficiency filter element 322 and a purification fan 323 .

The outdoor air is sucked in by the purification fan 323 through the air inlet 307 of the outer shell 30, and first passes through the primary filter element 320, which intercepts large particles of pollutants and mosquitoes, and then passes through the medium-efficiency filter element 321 and the high-efficiency filter element in turn. Filter 322, purify, intercept PM2.5 particles, absorb formaldehyde, decompose cold bacteria, and fresh air enters the room. The fan mounting plate 324 is provided with a shock-absorbing gasket, which strengthens the airtightness of the air inlet of the purification fan and reduces the vibration of the fan.

The purification fan 323 in the air inlet purification area 32 is staggered up and down in series to increase the air intake, and forms a front and rear sealed pipeline with the internal fixed block 35, the cover plate system 4, and the outer shell 1, thereby reducing the loss of air volume, so that the fresh air can only come from Enter the muffler area of the air duct on the right.

The air duct muffler area 33 is used to reduce the fresh wind noise coming from the purification area. It is mainly composed of double-layer "back" shaped polyester fiber sound-absorbing panels, including outer and inner sound-absorbing channels, and the gap between the shell and the shell forms a cavity. Polyester fiber sound-absorbing panels are porous sound-absorbing materials, and there are a large number of tiny connected pores inside. Sound waves can penetrate deep into the material along these pores, and rub against the material to convert sound energy into heat energy. In the noise range of 125-4000HZ, the sound absorption coefficient reaches greater than 0.9, and the sound absorption effect is good for medium and high frequencies. When the fresh air enters the noise reduction channel, one is to directly use the porous sound absorption principle of the sound-absorbing board to absorb medium and high-frequency noise; the other is to pass through the outer layer. The cavity uses the sound absorption principle of the back cavity to increase the low-frequency sound absorption capacity.

The ANC control area 34 is located at the air outlet section of the ventilator shell system. The ANC control area includes a three-way air outlet pipe 10, one end of the three-way air outlet pipe 10 is connected with a variable diameter pipe 11, the other end is connected with a noise-absorbing speaker 12, and the last end It communicates with the air outlet 13 of the outer panel 8, and the fresh air enters the panel system through the three-way air outlet pipe 10, and finally enters the room.

ANC control area: Active noise reduction control area, which actively reduces noise for the low-frequency (50-300HZ) line spectrum noise emitted by the purification fan, and reduces the operating noise of the purification fan.

The principle of active noise reduction: Using the phenomenon of sound wave interference and cancellation, the speaker emits sound waves with equal frequency and opposite phase to the original noise, which are superimposed and canceled with the original noise, thereby reducing noise.

2) Control method: Active noise control is carried out by means of feedback control.

The hardware of the ANC control area is mainly composed of three major blocks, which are audio acquisition device, active noise reduction main control platform and control sound source. The audio acquisition device is a microphone and a preamplifier; the control sound source is a speaker; the active noise reduction main control platform includes a DSP core, an A/D converter, a D/A converter, an anti-aliasing filter, and a reconstruction filter , Power management module, power amplifier, man-machine interface.

The specific implementation of active noise reduction: the audio acquisition device detects the 50Hz-300Hz low-frequency line spectrum noise emitted by the purification fan, converts the acoustic signal into an electrical signal and transmits it to the main control platform, and the main control platform amplifies and filters the obtained signal , Data sampling, spectrum analysis of the collected low-frequency noise of the purification fan, to obtain the frequency band and main frequency of the noise of the purification fan.

Use the single-frequency sinusoidal signal of the corresponding frequency as the excitation signal, use the FXLMS algorithm to identify the secondary channel of the corresponding frequency, obtain the coefficient of the adaptive filter of the secondary channel and store it; after the identification is accurate, enter the ANC control, the main control platform Calculate the control signal with equal amplitude and opposite phase to the noise of the purification fan. The control signal is converted by the converter, filtered by the filter, amplified by the power amplifier, and output by the control sound source speaker installed on the air outlet side. The output sound wave and The frequency of the original noise of the purification fan is equal and the phase is opposite, and the two are superimposed and cancelled, thereby reducing the low-frequency noise of the fan.
