Description

The present invention relates to a hair-cutting attachment that is attached to the suction hose side of a vacuum cleaner and cuts off human hair, animal hair, and pills formed on clothing and carpets.

Conventionally, a hair-cutting attachment (hairball remover) attached to the tip of a suction hose of a vacuum cleaner has been used to remove hairballs formed on clothes or carpets. The attachment for shaving includes a cylindrical case (cylindrical case) having a connecting pipe (vent pipe) attached to and detached from the tip of the suction hose, and fixed to the opening of the case to form a large number of suction holes. It has a suction plate (clothing contact surface), and a rotating shaft connecting the windmill and the rotary blade is rotatably supported in the case (see, for example, Patent Document 1).

The wind turbine has a plurality of blades arranged diagonally with respect to the axial direction at one end of the rotating shaft, and the rotary blades are fixed to the other end of the rotating shaft and arranged radially around the rotating shaft. It has multiple blades (cutters). A plurality of blades of the rotary blade are in sliding contact with the inner surface of the suction plate.

In the hair-cutting attachment described in Patent Document 1, when a vacuum cleaner is used, an air flow is generated in the case from the suction plate to the connecting pipe. When the airflow hits the blade portion, the wind turbine rotates, and the blade portion of the rotary blade rotates around the rotation shaft via the rotation shaft. At this time, by bringing the suction plate into contact with clothing or carpet, the pills sucked into the suction holes are cut by the blade portion of the rotating rotary blade. The cut pills are sucked into the suction hose of the vacuum cleaner from inside the case via the connecting pipe. As a result, the hair-cutting attachment can continuously remove pills from clothes and carpets when using the vacuum cleaner, and the cut pills are sucked in by the vacuum cleaner without accumulating in the case. No need to clean the inside of the case.

Each arm portion 17b has a predetermined width and is arranged so as to be 90 degrees. The arm portion 17b has a pair of engaging claws 17c integrally formed on one side edge portion in the circumferential direction. A straight line along the side edge of the arm portion 17b on the other side in the circumferential direction passes through the center of the rotation axis 16.

The pair of engaging claws 17c are arranged on both sides of the arm portion 17b in the length direction. As shown in FIG. 8 (a), the pair of engaging claws 17c are formed so as to project inward in the length direction of the arm portion 17b from the extending portion extending in the axial direction to the other in the circumferential direction.

A blade with blade 18 is attached between each arm portion 17b and the pair of engaging claws 17c. As shown in FIG. 2, the blade with blade 18 is formed in a sheet shape having a blade portion 18a and a blade portion 18b fixed to the blade portion 18a. The blade portion 18a has a fan-shaped portion forming a fan shape of 90 degrees, and a fixing portion 18c extending from one of the radial side edges of the fan-shaped portion and to which the blade portion 18b is fixed. The blade portion 18a has notches 18d formed on both edges of the blade portion 18a at a position closer to the fixed portion 18c. The notch portion 18d is adapted to engage with a pair of engaging claws 17c of the arm portion 17b. The blade portion 18a is formed by superimposing two flexible sheet-like objects. The blade portion 18b is sandwiched between the portions of the blade portion 18a that serve as the fixing portions 18c of the two sheet-like objects, and a part of the blade portion 18b is exposed.

The blade portion 18b is a rectangular metal blade, and is formed with a sharp cross section over the entire length of the arm portion 17b in the length direction. The blade portion 18b is linearly in contact with the inner surface of the suction plate 14 in a state where the blade portion 18 with blades is attached to the arm portion 17b.

The blade 18 is arranged between the arm portion 17b and the pair of engaging claws 17c in a state where the blade portion 18b is located on the other end side in the axial direction with respect to the arm portion 17b. Each engaging claw 17c is engaged with the cutout portion 18d of the blade portion 18a. The blade 18 is attached to the arm portion 17b in a state where the blade 18 is tilted to one side in the circumferential direction with respect to the central axis of the rotating shaft 16 and the tip edge of the blade portion 18b is linearly in contact with the inner surface of the suction plate 14.

The blade 18 with blades is removable from the arm portion 17b. To attach the blade 18 with blades, the blade 18a is bent so that the cutouts 18d are close to each other, and the blades 18b are located on the other end side in the axial direction with respect to the arm portion 17b. Is engaged with the engaging claw 17c of the arm portion 17b. On the other hand, the blade 18 with blades 18 is removed by bending the blades 18a so that the cutouts 18d come close to each other and separating the cutouts 18d from the engaging claws of the arm 17b.

In the state where the blade 18 with blades is attached to the arm portion 17b, the fan-shaped portion of the blade portion 18a is located on one side in the axial direction with respect to the arm portion 17b. At this time, the arcuate outer edge of the fan-shaped portion of the blade portion 18a extends in one axial direction as it goes toward one in the circumferential direction along the outer peripheral edge of the suction plate 14. The blade portion 18a in this state receives the airflow generated in the case 11 from the suction hole 15 of the suction plate 14 toward the discharge port portion 12 of the case 11. The blade portion 18a that has received the airflow rotates around the rotation holder 17 on the other side in the circumferential direction. Due to the rotation of the rotary holder 17, the blade portion 18b of the blade with blade 18 rotates while being in sliding contact with the inner surface of the suction plate 14.

The hair-cutting attachment 10 according to the embodiment of the present invention is configured as described above. As shown in FIG. 10, the hair-cutting attachment 10 according to this embodiment connects the joint portion 11c of the case 11 to the tip of the suction hose H of the vacuum cleaner C. When the power of the vacuum cleaner C is turned on, air is sucked from the tip of the suction hose H, and an air flow is generated in the case 11 from the plurality of suction holes 15 of the suction plate 14 toward the discharge port portion 12 of the case 11.

The blade portion 18a of the blade 18 with blades receives this air flow. The blade portion 18a that has received the airflow rotates around the rotation holder 17 on the other side in the circumferential direction. Due to the rotation of the rotary holder 17, the blade portion 18b of the blade 18 with blades rotates around the rotation shaft 16 while sliding contact with the inner surface of the suction plate 14. In this rotated state, the case 11 is held in the hand, and for example, the suction plate 14 is moved along the body surface of the pet P (dog in FIG. 10). At this time, the hair of the pet P is sucked into the case through the suction hole 15, and a part of the hair is cut by the blade portion 18b of the blade with blade 18. The cut hair is sucked into the vacuum cleaner C from the discharge port 12 through the suction hose H together with the air flow generated in the case 11. In this way, the cut hair is sucked into the vacuum cleaner C without falling around the pet P, so that cleaning of the ground and the floor surface becomes unnecessary.

Further, the hair-cutting attachment 10 can cut a person's hair and suck the cut hair into the vacuum cleaner C by moving the case 11 along the person's scalp in the above-mentioned rotating state. Further, by moving the case 11 along the surface of clothing or carpet, the pills can be cut and sucked into the vacuum cleaner C. As shown in FIG. 11, the hair-cutting attachment 10 can also be directly connected to the suction port portion of the vacuum cleaner C.

Further, in the hair cutting attachment 10, the blade portion 18a that receives the airflow generated in the case 11 and the blade portion 18b that is in sliding contact with the inner surface of the suction plate 14 are integrally formed as a sheet-shaped blade with blade 18. ing. The blade 18 with blades is attached to the arm portion 17b of the rotary holder 17. Therefore, the length of the rotating shaft 16 that supports the bearing portion 17a of the rotating holder 17 can be reduced.

Further, the blades 18 with blades are detachably attached to a plurality of arm portions 17b of the rotary holder 17, respectively. Therefore, when the blade portion 18b is chipped or the blade portion 18b becomes dull, the blade 18 with blades can be removed from the arm portion 17b and easily replaced.

Further, as shown in FIG. 9, the suction plate 14 is formed so that a plurality of suction holes 15 are formed along a direction orthogonal to the radial direction. As a result, the hairs sucked into the suction holes 15 of the suction plate 14 are arranged in a direction orthogonal to the blade portion 18b of the blade 18 with blades. The hairs lined up in this way are sequentially cut by the blade portion 18b from the inner portion to the outer portion in the radial direction thereof, and the hairs are smoothly cut.

The blade portion 18a of the blade 18a has an arc shape of the fan-shaped portion of the blade portion 18a, which has a fan-shaped portion and a fixing portion 18c extending from one of the radial side edges of the fan-shaped portion and fixing the blade portion 18b. The outer edge is in a state of extending in one axial direction toward one in the circumferential direction along the outer peripheral edge of the suction plate 14. Therefore, when the vacuum cleaner C is used, the turbulence of the airflow generated in the case 11 is less likely to occur, and the fluctuation of the rotation speed of the rotation holder 17 to which the plurality of blades 18 with blades 18 are attached can be suppressed.

Since the blade portion 18a has flexibility, the inclination of the blade portion 18a with respect to the central axis becomes smaller as the velocity of the airflow generated in the case 11 increases. On the other hand, when the velocity of the airflow generated in the case 11 becomes small, the inclination of the blade portion 18a with respect to the central axis of the rotating shaft 16 becomes large. As a result, even if the speed of the airflow generated in the case 11 changes depending on the model of the vacuum cleaner, the fluctuation of the rotation speed of the rotation holder 17 can be suppressed.
