Description

[Technical field]

[0001] The invention relates to a filtering type noise-absorbing and ventilation device, belonging to the field of ventilation devices for sealed shock absorbers, and in particular to a filtering type noise-absorbing and ventilation device. [Background technology]

[0002] The sealed corrosion-resistant shock-absorbing device is a shock absorber used by sightseeing boats traveling in water and on mudflats. Its shock-absorbing components work in a sealed space. The volume of the sealed space of the shock absorber changes constantly during operation. The ventilation holes of the shock absorber make noise when discharging gas, and the dust in the atmosphere is inhaled during inhalation, which reduces the life of the shock absorber components and the working effect. The existing filtering devices cannot eliminate noise due to design reasons, and the existing silencers cannot filter due to design reasons. Therefore, the existing technology cannot meet the use requirements of the sealed corrosion-resistant shock-absorbing device. A filtering silencer ventilation device is installed on the sealed shock-absorbing device of the walking boat, so that the shock absorber can filter air and eliminate exhaust noise, ensuring good working effect and service life.
