Next, the structure of the adapter 4 portion will be explained in detail based on the embodiment shown in FIGS. 4 and 5. At the rear end opening of the housing 1, there is a suction port lattice 14 within the opening edge, which is composed of circular ribs 33 formed concentrically at intervals and radial ribs 34 formed radially toward the center. The air suction ports 2 are provided toward the center outward from the periphery, and the air suction ports 2 are formed between the respective suction port grids 14, 14. A cylindrical protrusion 19 is provided at the tip of the suction port grid 14 at the center of the rear end opening of the housing 1 . A pair of recessed stepped surfaces 35 are formed on the peripheral wall of the protrusion 19 and are recessed from the upper end surface of the protrusion 19 to approximately the center thereof, facing each other at an angle of 180 degrees. A guide groove 20 is recessed therein, and an engagement recess 31 is recessed in the other side of the recessed step surface 35. Projection 19
A rotary connector 7 is housed inside the rotary connector 7, and an electric cord 3 electrically connected to the motor 9, heater 11, etc. inside the housing 1 is passed through the rotary connector 7, and the electric cord 3 is connected to the rotary connector 7. It is designed to lead out from the inside of the housing 1 to the outside. 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. A fixing protrusion 23 formed at the lower part of the ring 22 is engaged with a protrusion insertion opening 24 of the protrusion receiving portion 21. The adapter 4 is made of a slightly elastic synthetic resin material, etc.
As shown in FIG. 4, the housing 1 is formed into a substantially truncated conical shape with an open side on the housing 1 side by a circumferential reinforcing rib 25, an insertion rib 26, and a plurality of adapter grids 27, 27 extending between the ribs 25, 26. There is. This adapter 4 can be molded, for example, by injection molding, and has good moldability. A cord insertion hole 5 is formed in the center of the adapter 4, and a notch 6 is provided in the adapter 4 extending from the cord insertion hole 5 to the peripheral edge of the adapter 4, so that the adapter 4 can be bent. The opening width of the cut 6 can be changed. 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, 36 is a main switch.

Therefore, when attaching the adapter 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, with the notch 6 closed, the adapter 4 is fitted into the protruding part 19. The insertion rib 26 of the adapter 4 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 29 of the cylindrical cover 8 into the guide groove 20 of the protruding part 19 from the outside of the adapter 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 Engaging recess 3

In this way, the reinforcing rib 25 of the adapter 4 is pushed toward the housing 1 by the cylindrical cover 8, and the adapter 4 is clamped between the protrusion 30 on the inner peripheral wall of the housing 1 and the cylindrical cover 8. The adapter 4 is securely fixed to the housing 1 so as to cover the air suction port 2 of the housing 1 without opening the notch 6. Here, the adapter grid 27 of the adapter 4
runs in a direction perpendicular to the circumferential direction of the adapter 4, while the inlet grid 14 has concentric circular ribs 3.
3, the adapter grid 27 and the suction port grid 14 intersect when viewed from the air suction direction, and a fine net-like filter is formed here by the respective grids 27 and 14. ,
The air sucked into the housing 1 can be filtered without any problem. Further, the adapter 4 is formed into a substantially truncated conical shape, and a space 37 is formed between the adapter 4 and the suction port grid 14, and the space 37 is formed between the adapter 4 and the suction port grid 14.
7 do not overlap, reducing air resistance during suction and improving suction efficiency. When cleaning the adapter 4 and the suction port grid 14 with dust, etc., first twist the cylindrical cover 8 to disengage the protruding dowel 29 and the engagement recess 31, and then remove the cylindrical cover 8. The adapter 4 is completely removed from the housing 1 by pulling out the cover 8 from the protrusion 19, then pulling out the adapter 4 from the protrusion 19 to open the width of the notch 6 in the adapter 4, and passing the electrical cord 3 through the notch 6. It can be easily cleaned.
In this way, the elasticity of the adapter 4 allows the end edge of the adapter 4 and the cord insertion port 5 to be attached to the air suction port 2 and the protrusion 19 in close contact with each other. By opening the width of the cut 6, the adapter 4 can be easily attached even if the air suction port 2 and the protrusion 19 are deformed. This allows the adapter 4 to be easily removed from the air suction port 2 by passing the electrical cord 3 through the notch 6. In this way, by bending the adapter 4 and changing the width of the notch 6, it can be attached to and removed from the adapter 2 with a single touch. Further, the adapter grid 27 and the suction port grid 14 of the adapter 4 have a larger inter-grid dimension than a conventional mesh filter, and are easy to clean.

FIG. 6 shows another embodiment in which the suction port grid 14 is formed by a large number of radial ribs 34, 34, . On the other hand, the adapter lattice 27 is formed by a large number of circular ribs 38, 38, .
It is molded with. Even with this thing,
When the adapter 4 is fitted into the air suction port 2 of the housing 1, the adapter grid 27 and the suction port grid 14 intersect, forming a filter that is finer than the dimension between the respective grids, and dust prevention can be performed without any problem. . Further, FIGS. 7 and 8 show still another embodiment, in which the suction port grid 14 and the adapter grid 27 are respectively made into coarse net-like grids, as shown in FIG. The adapter 4 is attached to the housing 1 by shifting the respective net-shaped grids 14 and 27 in the air suction direction so that the grids do not overlap. A positioning rib 39 is provided at the bottom of the insertion rib 26 of the adapter 4.
The mounting position is determined by inserting the positioning rib 39 into a positioning recess (not shown) provided at the rear end of the housing 1. Even in this case, when the adapter 4 is fitted into the air intake port 2 of the housing 1,
The adapter grid 27 and the suction port grid 14 intersect to form a fine-mesh filter, and when cleaning the adapter 4, the adapter 4 can be easily removed from the housing 1. Since it is coarse, dust and hair can be easily removed.

As described above, the present invention provides a suction port grid at the rear end opening of the housing, forms an air suction port between the suction port grids, and provides an adapter grid on an adapter that is detachably attached to the outside of the air suction port. Since the grid positions of the adapter grid and the above-mentioned suction port grid are shifted in the air suction direction, the suction port grid and the adapter grid intersect and can cover the air suction port of the housing as a filter with fine mesh between the grids. The air sucked into the housing from this air suction port can be filtered without any problem. Also, since the adapter is detachable, you can easily remove the adapter if it is clogged with dust. The adapter grid and suction port grid can be removed from the housing and cleaned separately, and the dimensions between the grids are larger than conventional mesh filters, making cleaning easier.Moreover, the adapter has elasticity. The adapter is formed into a substantially truncated conical shape with an opening on the housing side, and a cord insertion hole is formed in the center of the adapter, as well as a notch that extends from the cord insertion hole to the edge of the adapter. The edges of the adapter can be installed closely together, and the width of the notch can be changed by bending the adapter. It is easy to install, and on the other hand, by opening the width of the notch, an electrical cord can be passed through the notch and the adapter can be easily removed from the air intake port. In this way, by bending the adapter and changing the width of the cut, it can be attached to and removed from the air suction port with a single touch.
