Registered Utility Model No. 3143309

  In the suction nozzles of these various conventional vacuum cleaners, as seen in Patent Documents 1 and 2 and Non-Patent Document 1, the nozzle used by being inserted into the tip of the suction cylinder always has an air suction surface. It was inserted into the suction cylinder so as to face the floor. This is because if the air suction surface is separated from the floor surface, the suction force decreases and cleaning becomes impossible. Therefore, use as another posture has not been considered at all.

  However, the place to be cleaned using a vacuum cleaner is not limited to the floor surface. For example, the upper surface of an air conditioner or refrigerator, the upper surface of a light shade, the upper surface of a clothes dance or a cupboard, etc. are surfaces to be cleaned by suction using a suction nozzle. These high-level surfaces to be cleaned cannot be cleaned with the conventional vacuum cleaner because the air suction surface faces upward even if the suction nozzle is replaced by rotating it up and down with respect to the suction cylinder.

  Therefore, in order to solve the problem that the conventional electric vacuum cleaner has, the present invention adds a contrivance to the suction nozzle so that not only cleaning of the floor surface but also cleaning of the high position is very simple operation. The suction nozzle that can be cleaned by changing the posture is proposed here.

  The configuration of the vacuum cleaner nozzle according to the present invention taken to achieve the object will be described. The vacuum nozzle is used by being attached to the tip of the suction cylinder in the vacuum cleaner, and includes an air suction port and a cleaning nozzle. A brush body 1 having a brush 3 and a cylinder body 2 connected to the brush body 1, a connection cylinder 11 to the cylinder body 2 in the brush body 1, and a connecting cylinder 21 to the brush body 1 in the cylinder body 2, Are formed in such a diameter that can be fitted, and either one of these tube portions 11 and 21 has two cuts 43 and 43 cut from the tube end 41 toward the tube back portion 42, and between these cuts. A projection 45 projecting in the radial direction of the cylindrical body is formed in the remaining portion 44, and the projection 45 is located when either of the cylindrical portions 11 and 21 is fitted into one of the other cylindrical portions. 2 facing each other in the circumferential direction of the location It is the protrusion 45 is window holes 51 for projecting and retracting formed at, in which the cylindrical body 2 has a structure that has a bent portion 23 at the other portions except the connecting tube 21.

  The vacuum cleaner nozzle according to the present invention has a diameter capable of fitting the connecting cylinder portion of the brush body 1 having the air suction port and the cleaning brush 3 and the connecting cylinder portion of the cylinder body 2 connected to the brush body. It is assumed that two cylindrical cuts are made in any one of these cylindrical portions, and a protrusion protruding in the radial direction of the cylindrical body is formed in the remaining portion between the two cylindrical portions. In addition, since both the cylindrical portions are formed with window holes in which the projections protrude and retreat in two locations facing each other in the circumferential direction of the location where the projections are located, The protrusion is protruded from the other window hole by rotating the brush body 1 and the cylindrical body 2 relative to each other by pressing the tip of the protrusion protruding from any one of the window holes. It is possible to change the relative posture between the brush body 1 and the cylinder body 2 with a simple operation In addition, since the cylindrical body 2 is provided with a bent portion in the other part except the connecting cylinder, for example, it is possible to obtain an excellent convenience that a high position such as an air conditioner upper surface can be cleaned from a floor surface cleaning posture. There is an effect that can be.

  In carrying out the vacuum cleaner nozzle of the present invention configured as described above, the diameter of the cylinder opposite to the connecting cylinder connected to the brush body can be inserted and connected to the suction cylinder in the vacuum cleaner. It is preferable to keep the diameter. More preferably, by setting the diameter to be able to be inserted and fixed at the tip of the suction cylinder, the suction can be smoothly used without a dust trapped portion. The window holes formed in the connecting cylinders of the cylinders are not limited to two places facing each other in the circumferential direction, but are assumed to be formed at four places that are phased approximately 90 degrees in the circumferential direction, and the brush is oriented sideways. Thus, it is also preferable to carry out by facilitating the cleaning of the lateral wall surface of a building or the like, or the lateral surface of the air conditioner or chiffon. In addition, if the cylinder body is formed in a front shape and bent in a dogleg shape, the object of the present invention can be achieved even if the suction cylinder of the vacuum cleaner has a straight shape without a bent portion. It is preferable at the point which can do.

  A first embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, the suction nozzle used by attaching to the tip of the suction cylinder in the vacuum cleaner according to the present invention has an air suction port (not shown) on the lower surface of the main body cylinder portion 12. The brush main body 1 is provided with a connecting cylinder 11 for connecting a cleaning cylinder 3 around the main cylinder section 12 and connected to the cylindrical body 2 on one end side of the main body cylinder section 12, and the brush main body 1 on one end side. A connecting cylinder 21 connected to the connecting cylinder 11, an insertion cylinder 22 connected to the suction cylinder 6 of the vacuum cleaner at the other end, and a cylinder 2 having a bent portion 23 between the two cylinders 21 and 22. It is comprised by one member.

  The connecting cylinder 11 formed on one end side of the brush body 1 and the connecting cylinder 21 formed on one end side of the cylinder body 2 are formed with a diameter that can be fitted. In this embodiment, the brush body One connecting cylinder 11 has a small diameter, the connecting cylinder 21 of the cylinder 2 has a large diameter, and the connecting cylinder 11 of the brush body 1 is inserted and fitted into the connecting cylinder 21 of the cylinder 2.

  Thus, the connection tube 11 of the brush body 1 is formed with two cuts 43, 43 cut in parallel from the tube end 41 toward the tube back portion 42, and is left between the cuts. The portion 44 is swingable in the thickness direction, and a small projection 45 is formed on the portion 44 so as to project in the radial direction of the cylindrical body. The connecting cylinder 21 of the cylindrical body 2 into which the connecting cylinder 11 is fitted is formed. Are located at two locations facing each other in the circumferential direction of the portion where the projection 45 is located when both the cylindrical portions 11 and 21 are fitted, and in the embodiment, at two locations on the front side and the back side. In this structure, a window hole 51 is formed in which the protrusion 45 protrudes and retracts.

  The suction nozzle having such a structure is used by inserting and fitting the connecting cylinder 11 of the brush body 1 to the connecting cylinder 21 of the cylinder 2 as described above. The form at the time of use is as shown in FIG. 3 and FIG. The state of FIG. 3 is mainly suitable for cleaning at a low position such as a floor surface or a sill. In this state, the brush body 1 and the cylinder 2 are moved 180 degrees while pressing the head of the protrusion 45 protruding from the window hole 51. When the relative rotation is performed, the protrusion 45 protrudes from the other window hole 51 as shown in FIG. 4, and the subsequent relative rotation is prevented. As this state, cleaning can be performed in a state suitable for cleaning at a high position such as an upper surface of an air conditioner or a chest. In this embodiment, the window holes 51 are shown as being formed on the front side and the back side, but may be formed at the upper and lower positions.
