The design principle of the filtering device of the helmet is to drive air through a series of purification materials, such as filter screens, filter membranes, filter elements, etc. by the power when the rider breathes, so as to filter out harmful particulate matters and pollutants in the air. Due to the tightness of the filtering device and the obstruction of the air flow by the filtering materials, the rider feels stuffy when wearing such helmets for a long time; when the air quality improves, the rider hopes to remove the filtering device inside the helmet to restore smoother air flow and improve the wearing comfort. However, at present, it is relatively difficult to disassemble the filtering device inside the helmet, and usually professional tools are required for disassembly, such as screwdrivers, etc., resulting in that the rider cannot disassemble the filtering device at any time, causing inconvenience in use. Content of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides a dual-purpose helmet with a detachable ventilation device, aiming to solve the technical problems that it is relatively difficult to disassemble the filtering device inside the helmet, and usually professional tools are required for disassembly, resulting in that the rider cannot disassemble the filtering device at any time, causing inconvenience in use.

[0004] The technical solution of the utility model to solve the above technical problems is as follows:

An activity hole is opened inside the fixed bracket. A limit post is slidably connected inside the activity hole. One end of the limit post extends into the limit socket, so that the extending end of the limit post closes the limit socket. A limit plate is provided at one end of the fixed insertion post. The limit plate and the installation cavity are separated to form a limit interval. The fixed bracket is located inside the limit interval.

[0006] When air filtration is required, the filtration device is placed in the installation cavity. Align the fixed brackets at both ends of the filtration device with the fixed insertion posts in the installation cavity, so that the limit sockets of the fixed brackets are inserted into the fixed insertion posts. The fixed brackets are located within the limit interval separated by the limit plate and the installation cavity. One end of the limit post slides into the interior of the limit socket through the movable hole, so that the extended end of the limit post closes the limit socket, thereby fixing the position of the filtration device. When the filtration device needs to be disassembled, simply pull out the limit post so that the limit socket of the fixed bracket disengages from the fixed insertion post, replacing the existing disassembly and installation methods using tools such as screwdrivers, thus simplifying the installation and disassembly process of the filtration device.
