Next, the structure of the filter 4 portion will be described in detail based on the embodiment shown in FIGS. 4 and 5. At the rear end opening of the housing 1, a suction port lattice 14 is formed extending outward from the center from the inner periphery of the opening edge, and an air suction port 2 is formed between each of the suction port lattices 14, 14. A cylindrical protrusion 19 is provided at the tip of the suction port lattice 14 in the center of the rear end opening of the housing 1, and a cylindrical protrusion 19 is provided on the circumferential wall of the protrusion 19, extending from the upper end surface of the protrusion 19 to the lower part of the circumferential wall. A pair of guide grooves 20 are provided opposite each other at an angle of 180°. An engagement recess 31 is further provided near the guide groove 20. A rotary connector 7 is housed in the protrusion 19, and an electric cord 3 electrically connected to the motor 9, heater 11, etc. is passed through the rotary connector 7.
is led out from inside the housing 1 via the rotary connector 7. A protrusion receiving part 21 formed of an H-shaped rib piece is attached to the lower circumferential wall of the protruding part 19 as a part of the suction port grid 14, and a cylindrical fixing ring 22 is fitted into the protruding part 19 to fix it. ring 2
A fixing protrusion 23 formed at the lower part of the protrusion 2 is engaged with a protrusion insertion opening 24 of the protrusion receiving part 21. The filter 4 is made of elastic synthetic resin material, etc.
As shown in FIG. 4, it is formed into a substantially truncated conical shape with the housing 1 side open, and reinforcing ribs 25 and insertion ribs 26 are formed along the circumferential direction on the upper and lower sides thereof. Further, a filter lattice 27 is provided between both ribs 25 and 26 to reinforce the filter 4, and a lattice-shaped net 28 is provided between each rib 25 and 26, and the air is filtered by this net 28. be. A cord insertion opening 5 is formed in the center of the filter 4, and two notches 6 are provided in the filter 4 extending from the cord insertion opening 5 to the outer periphery of the filter 4. It is divided into halves 4a and 4b.
The cylindrical cover 8 is formed into a cylindrical shape, and a pair of protruding dowels 29 are provided at the lower part of the inner periphery thereof facing each other as shown in FIG. In the figure, 32 is a switch.

Therefore, when attaching the filter 4 to the rear end of the housing 1, first the fixing ring 2
2 into the protruding part 19 and the fixing protrusion 23 of the fixing ring 22 is engaged with the protrusion insertion opening 24 of the protrusion receiving part 21. Next, the filter 4 is fitted into the protruding part 19 and the insertion rib 26 of the filter 4 is fitted. is engaged with a protrusion 30 protruding from the inner circumferential wall of the rear end of the housing 1. Next, while inserting the protruding dowel 8 of the cylindrical cover 8 into the guide groove 20 of the protruding part 19 from the outside of the filter 4, the cylindrical cover 8 is fitted onto the outer periphery of the protruding part 19, and then the cylindrical cover 8 is twisted and the protruding dowel 29 is engaged with the engagement recess 31. In this way, the reinforcing rib 25 of the filter 4 is pushed toward the housing 1 by the cylindrical cover 8, and the filter 4 is clamped between the protrusion 30 on the inner peripheral wall of the housing 1 and the cylindrical cover 8. . The filter 4 is pressed against the filter half 4
This filter 4 covers the air suction port 2 of the housing 1 without creating a gap at the notch 6 due to being pushed in the direction where a and 4b are brought together, and the air sucked into the housing 1 can be filtered without any problem. . On the other hand, when removing the filter 4 from the housing 1 when the filter 4 is clogged with dust, etc., twist the cylindrical cover 8 in the reverse order to the above to engage the protruding dowel 29 and the engagement recess 31. After removing the cylindrical cover 8, the filter 4 is removed. Since the filter 4 is divided into two parts, there is no need to remove it along the electric cord 3, and it can be completely separated from the housing 1.

As described above, the present invention provides a cord insertion hole through which an electric cord is passed through the filter detachably attached to the air intake port of the housing, and divides the filter into a plurality of pieces with cuts passing through the cord insertion hole. If you want to remove the filter from the housing because it is clogged with hair, etc., you can separate the filter and completely separate it from the housing by passing an electric cord through the cord insertion hole of the filter and removing the filter. This makes it easy to clean hair, hair, etc. Moreover, the periphery of the housing side of the filter, which is divided into a plurality of pieces, is engaged with the inner peripheral surface of the rear end opening of the housing, and the cord insertion port of the filter is pressed toward the housing side by the cylindrical cover fitted around the outer periphery of the rotary connector. This allows the filter to be attached to the rear end of the housing. In other words, when fixing the filter divided in the circumferential direction, the periphery of the divided filter on the housing side is engaged with the inner peripheral surface of the rear end opening of the housing. Then, the filter can be installed by sandwiching the divided filter between the housing and the cylindrical cover with the cylindrical cover fitted on the rotary connector, that is, the cylindrical cover can fix the divided filter and prevent it from separating. In addition, since the cylindrical cover and housing can sandwich and install the divided filter,
By simply retracting the cylindrical cover slightly from the filter, in other words, the filter can be taken out without removing the cylindrical cover, and the filter can be removed with a slight movement of the cylindrical cover.
