The replacement of the auxiliary suction port according to the place is related to an auxiliary suction assembly for a vacuum cleaner.

1 shows a configuration of a general vacuum cleaner. As shown in the drawing, the main body 10 of the vacuum cleaner includes suction means (not shown) for sucking air in the room, and filtering means (not shown) for separating foreign matter from the air sucked by the suction means. And the suction hose 12 is connected.

The suction hose 12 is made of a flexible material, the operation handle 14 for the operation operation of the vacuum cleaner is connected to the end. And the operation handle 14 is connected to the suction nozzle 18 by the extension tube 16, the suction nozzle 18 is the air in the room by the suction force generated by the suction means of the main body 10 Inhale.

However, since the suction nozzle 18 has a wide bottom and is shaped to be flat, there is a structural limitation in transmitting suction to a place such as a bedding or window frame. In order to solve this problem, various types of auxiliary suction holes are used. For example, a knife-shaped auxiliary suction hole having an inlet portion pointed to a point, a brush suction hole provided with a brush at the inlet portion, etc. are typical auxiliary suction holes.

The knife-shaped auxiliary suction opening 20 shown in FIG. 2A has a sharply shaped inlet portion 22 and a connection portion in communication with the inlet portion 22 and connected to an end of the extension tube 16 (see FIG. 1) of the vacuum cleaner. It consists of 24. In addition, the brush suction opening 30 illustrated in FIG. 2B communicates with the inlet 32 formed at the front, the brush 34 provided around the front surface of the inlet 32, and the inlet 32. It consists of a connection 36 connected to the end of the extension tube 16 (see FIG. 1) of the vacuum cleaner.

In order to clean using the auxiliary suction hole such as the knife-type auxiliary suction hole 20 or the brush suction hole 30, first, as shown in FIG. 1, the suction nozzle 18 connected to the end of the extension pipe 16 is separated and , Connect the auxiliary suction port to the end of the extension tube (16). Therefore, the user may not only clean the deep part of the narrow gap such as a window frame or a door gap by using the knife-type auxiliary suction port 20, but also suction by using the brush 34 provided in the brush suction port 30. The foreign matter in the bedding which is difficult to clean with the nozzle 18 can be shaken off and sucked out.

However, the conventional vacuum suction auxiliary suction port having such a configuration has the following disadvantages.

The knife-type auxiliary suction opening 20 is useful for cleaning a gap larger than the size of the inlet portion 22, such as a window frame or a door gap. Since the inlet part 22 cannot be contacted, it does not transmit strong suction force and thus does not have an effective cleaning.

And the knife-type auxiliary suction port 20 is used to clean the narrow gap, it is difficult to expect effective cleaning when the knife-type auxiliary suction port 20 is used for cleaning bedding and the like. In addition, the brush suction opening 30 is suitable for cleaning a place such as bedding, but not for cleaning a narrow gap. Therefore, the user separates the knife-type auxiliary suction port 20 or the brush suction port 30 from the end of the extension tube 16 according to the characteristics of the cleaning place, and then again, the brush suction port 30 or the knife-type auxiliary suction port 20. ) Has to be connected to the end of the extension tube 16 has the disadvantage that the cleaning is cumbersome.

The present invention is to solve such a conventional problem, it is an object of the present invention to provide an auxiliary suction assembly for a vacuum cleaner that can efficiently perform the cleaning of the narrow gap.

Another object of the present invention is to provide an auxiliary suction assembly for a vacuum cleaner that can easily replace the suction port according to the characteristics of the place to be cleaned or the size and amount of the foreign matter.

In the case of forming the suction ports 62, 64 and 66 in this manner, the frames 62a, 64a and 66a and the suction pipes 62c, 64c and 66c are separately manufactured and combined to form the suction ports 62 and 64. In comparison with the case of forming (66), the manufacturing process can be simplified, thereby reducing the manufacturing cost, time and work defect.

However, the suction pipes 62c, 64c, and 66c are formed of a flexible material for cleaning various gaps, and as described above, the frames 62a, 64a, 66a and the suction pipes 62c, 64c, and 66c are respectively formed. Since it is formed integrally, not only the suction pipes 62c, 64c, 66c which are in direct contact with the gap to be cleaned, but the entire suction ports 62, 64, 66 including the frames 62a, 64a, 66a are formed of a flexible material. do.

Therefore, in order to maintain the shape of the suction ports 62, 64 and 66, a plurality of insertion pipes 68a provided in the suction main body 68 are inserted at the rear ends of the suction holes 62b, 64b and 66b, respectively. . The insertion tube 68a is provided at the front of the suction body 68, and a coupling portion 68b communicating with the insertion tube 68a is provided at the rear. The engaging portion 68b is formed in a tubular shape in the longitudinal direction.

The rear end of the suction holes 62b, 64b and 66b is inserted into the insertion tube 68a of the suction main body 68 and then bonded to the suction protrusions 62b, 64b and 66b. By fixing to the suction hole 62b, 64b, 66b and the loss of suction force due to the inflow of external air from the insertion portion of the insertion projection (68a) can be prevented.

Meanwhile, the frame 62a of the first suction port 62, the frame 64a of the second suction port 64, the frame 66a of the third suction port 66, and the suction main body 68 each have a cylindrical shape. Can be formed. The opening 62d of the first suction opening 62 has a predetermined radius of curvature, and the outer circumferential surface of the frame 64a of the second suction opening 64 also has an opening 62d of the first suction opening 62. The second suction port 64 may be inserted into and fixed to the opening 62d of the first suction port 62 so as to have the same curvature radius. In addition, an outer circumferential surface of the opening 64d of the second suction opening 64 and the frame 66a of the third suction opening 66 is also formed to have the same radius of curvature, so that the third suction opening 66 is formed in the second suction opening ( It can be inserted and fixed in the opening 64d of the 64. The outer circumferential surface of the frame 62a of the first suction opening 62 and the suction main body 68 may also be formed to have the same radius of curvature.

However, as in this embodiment, the first suction port 62 and the second suction port 64, and the third suction port 66 and the suction body 68 are not necessarily formed in a cylindrical shape, the first The frame 62a of the suction port 62, the frame 64a of the second suction port 64, the frame 66a of the third suction port 66, and the suction body 68 may be formed in a quadrangular shape. .
