A filter provided in a conventional vacuum cleaner or a portable wireless cleaner is manufactured by using breathable fibers or filter paper, and is generally manufactured in a bag shape without a predetermined shape to minimize the influence on the suction power of the motor. When a certain amount of dust and foreign substances are collected in the filter, the user detaches the filters from the housing or the body of the cleaner to separate them from each other, and removes the dust and foreign substances from the filter. It will be mounted on the joint of the body part and the dust container and ready for reuse.

However, in the conventional vacuum cleaner as described above, since the filter is made of a thin fiber or filter paper, the filter is made of a bag-shaped dust collecting network, so that a continuous flow force is generated by the wrinkles and the action of the motor. This causes the service life to be significantly reduced.

In addition, there is a gap between the fiber or paper filter and the means for clamping the fiber or paper filter due to the frequent detachment, thereby causing foreign matter in the filter to flow into the gap to affect the motor and various driving circuits therein. Since the failure rate is increased, there is a problem of shortening the service life.

The present invention is to solve the above problems, to provide a removable filter assembly to remove the foreign matter in the air discharged by the motor on the outer surface of the housing rather than the inside of the housing to facilitate replacement. The purpose is to.

In addition, another object is to provide a filter assembly having high filtering efficiency by allowing the air sucked in the filter assembly to be spread evenly through the internal filter to remove foreign substances.

The filter assembly of the sterilization and cleaning device of the present invention for achieving the above object is an ultraviolet radiation unit provided with an ultraviolet lamp for emitting ultraviolet rays, an inlet formed to suck outside air, and an outlet formed on the side; Sterilization and cleaning device comprising a housing having an air passage connecting the inlet and the outlet, and a motor is provided inside the housing to discharge the air from the inlet side to the outlet side through the air passage Filtering means for filtering the foreign matter, is installed to purify the air discharged by the motor on the outer surface of the housing, characterized in that it comprises a case, hepa filter installed inside the case.

In addition, in the filter assembly of the sterilization and cleaning device of the present invention, the case, the first case having a plurality of suction holes for introducing the air discharged by the motor to the inside, and fixed the hepa filter, hepa filter And a second case having a plurality of discharge holes formed therein for discharging the purified air, wherein each of the first and second cases is further provided with a coupling protrusion for coupling to the housing. .

In addition, in the filter assembly of the sterilization and cleaning device of the present invention, between the hepa filter fixed to the second case and the first case, the air introduced through the suction hole of the first case is in wide contact with the hepa filter. An air diffusion space is formed to penetrate and purify, and the first case and the second case are fixed to be in contact with each other only so that the air diffusion space is formed.
