Claims

[Scope of utility model registration request]

A cylindrical fixed port is fixed to a part of the shielding box via a duct arranged to communicate with the inside of the box, and further includes an opening communicating with the duct and an exhaust duct communicating with the outside air, and a cylindrical fixed port inside the fixed port. At least two rigid parts are arranged in series, each having a component storage part, and an appropriate number of slits are formed on the outer periphery of at least one end protruding from the storage part in the axial direction so as to communicate with the inside of the fixed port. a cylindrical exchange port, and a filter stored in the parts storage part of each of the ports;
In order to provide sealing support between the outer circumferential surface of each exchange port and the inner circumferential surface of the fixed port, a compressive deformation member is placed between the two ports at intervals in the axial direction, and is also provided on the outer circumferential surface of each exchange port. a plurality of elastic rings fixed to each other; a flexible bag provided at one end of the fixed port for storing used replacement ports;
A retractable filter receiver for receiving used filters in the exchange port is provided with a device, and a slit in each exchange port is provided to prevent the filtration capacity of the filter from decreasing due to suction of the flexible bag. The bag receiver provided on the side end surface having a body and a pressure regulating damper provided at the other end of the fixed port and maintaining the pressure in the shielding box within a predetermined range. Features a filter exchange port structure in the shielding box.
