The partition mechanism comprises a sliding cavity 12 arranged inside a partition block 11, a vent groove 13 communicated with the sliding cavity 12 is formed in the side wall of the partition block 11 in a penetrating mode, the end, far away from an outer plate 2, of the vent pipe 5 is fixedly connected with the inner wall of the vent groove 13, the end, far away from a shaking groove 6, of the sliding cavity 12 is fixedly connected with a return spring 14, the end, close to the vent groove 13, of the return spring 14 is fixedly provided with a sliding block 15 in sliding connection with the inner wall of the sliding cavity 12 in a sealing mode, in a noise-free state, the magnetic block 10 and the sliding block 15 are staggered in the vertical direction, the magnetic block 10 is not located under the sliding block 15, attraction of the magnetic block 10 to the sliding block 15 is limited, the sliding block 15 can still keep an original position, the sliding block 15 is of an I-shaped structure, the size of the sliding block 15 can be reduced, the weight of the sliding block 15 is further reduced.

An air inlet hole 16 and an air outlet hole 17 communicated with the sliding cavity 12 are formed in the side of the partition block 11 far away from the outer plate 2, a one-way valve leading to the outside of the sliding cavity 12 is arranged in the air inlet hole 16, a one-way valve leading to the inside of the sliding cavity 12 to the outside of the sliding cavity 12 is arranged in the air outlet hole 17, the ventilation aperture of the air outlet hole 17 is smaller than that of the air inlet hole 16, namely, in the process that the sliding block 15 moves downwards, the space on the upper portion of the sliding cavity 12 is enlarged, external air can rapidly enter the sliding cavity 12 through the air inlet hole 16 with a larger aperture, the blocking reaction speed of the sliding block 15 is guaranteed, when the sliding block 15 is reset under the elastic action of the reset spring 14, the space on the upper portion of the sliding cavity 12 is reduced, and the air is discharged through the air outlet hole 17 with a smaller aperture, the gas discharge speed is obviously smaller than the air inlet speed, therefore, the reset speed of the sliding block.

In the invention, when the inner board 1 and the outer board 2 are put into use after being installed, and no obvious noise is generated outside, the sound wave impact on the external connecting rod 8 is small, the vibration generated by the external connecting rod is small, and the vibration transmitted to the elastic sheet 9 through the vibration transmission rod 7 is small, so that the sliding of the elastic sheet 9 is not enough to enable the magnetic block 10 to move to the position right below the sliding block 15, the attraction between the magnetic block 10 and the sliding block 15 is not enough, the sliding block 15 is in a high position under the elastic force action of the return spring 14, the two ends of the ventilation groove 13 are in a communicated state, the internal air flow exchange between the internal through groove 4 and the external through groove 3 is realized through the ventilation pipe 5, the indoor air exchange and the outdoor air exchange is realized, and the ventilation purpose is realized;

when more obvious noise appears outside, the sound wave during noise transmission has larger impact on the external extension rod 8, so that more obvious vibration appears on the external extension rod 8, the elastic sheet 9 can generate vibration after receiving the vibration through the vibration transmission rod 7, the vibration is enough to drive the magnetic block 10 to reciprocate to be right below the sliding block 15, the magnetic block 10 can attract the sliding block 15 to move downwards when being positioned right below the sliding block 15, so that the sliding block 15 can block the air channel 13, the circulation of the airflow on the inner wall is further blocked, the sound transmission can only be realized through the vibration transmission of the plate through the blocking of the internal airflow and the external airflow, the air transmission cannot be realized, the influence of the external noise on the indoor is greatly reduced, and the purpose of sound insulation is realized;

when the sliding block 15 moves downwards under the action of the attraction of the magnetic block 10, the air pressure in the upper space of the sliding cavity 12 is increased and reduced, so that the air outside the sliding cavity 12 quickly enters the sliding cavity 12 through the air inlet hole 16 under the action of the air pressure, when the magnetic block 10 shakes to and fro and leaves the position right below the sliding block 15, the sliding block 15 moves upwards under the action of the elastic force of the return spring 14, the air on the upper part of the sliding cavity 12 is extruded to be discharged through the air outlet hole 17 in the upwards moving process, the air discharging speed is slow due to the small aperture of the air outlet hole 17, so that the air pressure on the upper part of the sliding cavity 12 is difficult to reduce within a short time, the upwards moving speed of the sliding block 15 is obviously lower than the downwards moving speed of the sliding block, therefore, when the sliding block 15 is not restored, namely the obstruction of the air vent groove 13 is not contacted, when the indoor and outdoor air flow is not circulated, the vent groove 13 is in a blocking state, so that the sound insulation effect can be continuously kept when external noise is high and continuous operation is carried out; after the external noise disappears, the sliding block 15 is reset under the elastic force of the reset spring 14, the vent groove 13 is smooth, the air flow circulation is realized inside and outside, and the ventilation state is recovered.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
