Further, the hair ball remover 10 is provided with a lid portion 21 that opens and closes the battery 20 so as to be replaceable on one end side of the handle portion 11. The hair ball remover 10 is not limited to a dry battery type, and may be a rechargeable battery type that obtains power supply from an AC adapter.

  A neck portion 12 is provided on the other end side of the handle portion 11. The hair ball remover 10 includes a switch button 22 outside the neck portion 12, a motor 23 (electric motor) having a rotating shaft 25 (output shaft) inside the neck portion 12, and a printed circuit board (PCB) plate 24. .

  The PCB board 24 is provided with an electrical contact with the switch button 22. The fluff remover 10 is configured such that power can be supplied from the battery 20 to the motor 23 via the PCB plate 24 by switching the switch button 22. The motor 23 rotates the rotating shaft 25 at the same rotation speed in the clockwise direction (reverse rotation direction, one direction) and the counterclockwise direction opposite thereto (forward rotation direction, other direction) by switching the polarity. . A motor joint 26 connected to a connecting tool 27 described later is fixed to the rotating shaft 25. Note that the number of rotations can be varied depending on the rotation direction of the motor 23.

  The switch button 22 is provided so as to be able to reciprocate between, for example, three positions of the upper, middle, and lower stages in order to switch the use mode of the hair ball remover 10 depending on the state of the fabric and the size of the hair ball. For example, the hair ball remover 10 can be switched between the normal mode when the switch button 22 is in the upper position, the stop mode at the middle position, and the soft mode at the lower position. The use mode of the hair ball remover 10 differs in the rotation direction of the rotary shaft 25 of the motor 23. For example, it rotates clockwise (reverse rotation direction) in the soft mode and counterclockwise (forward rotation direction) in the normal mode. . Normal mode is used for thick fabrics with large hairballs, and soft mode is used for thin fabrics with small hairs.

  A head portion 13 is provided at the tip of the handle portion 11 through the neck portion 12. The hair ball remover 10 includes a connection tool 27 and an inner blade 30 on the inner side of the head portion 13, and an outer blade 31 on the outer side of the head portion 13.

  The connection tool 27 has an installation surface 27a on which the inner blade 30 is provided, and is an inner blade support tool that supports the inner blade 30 in a rotatable manner. This connection tool 27 has a shaft tube 28 fitted to the motor joint 26 so as to be prevented from rotating. The shaft cylinder 28 of the connection tool 27 is connected to the rotating shaft 25 of the motor 23 that extends into the head portion 13 via the motor joint 26.

  The inner blade 30 is rotatably provided in the clockwise direction (reverse rotation direction, one direction) and the counterclockwise direction (forward rotation direction, other direction) by switching the polarity of the motor 23 via the connector 27 by the motor 23. It is done. The inner blade 30 can be attached to and detached from the motor joint 26 in the axial direction (direction in which the shaft extends) in a state where the inner blade 30 is attached to the connector 27 (also referred to as an inner blade set).

  The outer blade 31 is detachable from the head portion 13 in a state of being attached to a ring-shaped cap portion 32 that can be screwed to the head portion 13 (also referred to as an outer blade set). The outer blade 31 has a blade hole (not shown) and is provided so as to cover the inner blade 30. For example, in a state where the inner blade 30 is rotated, the inner blade 30 is in contact with the inner surface of the outer blade 31, and pills that have entered the blade hole of the outer blade 31 are cut off by the inner blade 30, and the head portion 13 is left as it is. It will be taken inside.

A dust container 14 is provided below the head unit 13. The inside of the head unit 13 and the inside of the dust storage unit 14 communicate with each other through an opening 13a (see FIG. 3) of the head unit 13. And the dust ball taken in by the head part 13 is sent into the dust accommodating part 14 with the air flow which generate | occur | produces by rotation of the connection tool 27 (fan). The connection tool 27 has a fan piece 29 for generating an air flow on the side opposite to the side where the inner blade 30 is provided.

  The dust container 14 includes a dust box 34 having air holes 33. By providing the air holes 33, it is easy to generate an air flow from the head portion 13 to the dust accommodating portion 14. The dust box 34 is configured to be slidable in the dust container 14. When a hair ball accumulates in the dust box 34, for example, a finger can be put on the finger hook 34a and the dust box 34 can be slid downward to be removed, and the hair ball can be discarded.

  When removing a hairball using such a hairball remover 10, first, in a fabric such as a sweater, a clothes, a sock, a blanket, a portion where the hairball is to be removed is placed on a flat place, and the fabric is stretched. Next, the switch button 22 is turned on (normal mode or soft mode). Next, the head unit 13 is moved along the fabric to remove the hairball.

  As described above, the hair ball remover 10 has a function of, for example, a soft mode (reverse rotation mode) in which the inner blade 30 rotates in the clockwise direction (reverse rotation direction) and prioritizes the protection of the fabric, and the inner blade 30. Includes a function of becoming a normal mode (forward rotation mode) in which the cutting performance is prioritized by rotating counterclockwise (forward rotation direction). That is, the hair ball remover 10 prevents the cloth from having a hole by switching (selecting) the rotation direction of the inner blade 30 by a switch operation in accordance with the application (use situation). It has a structure that can Since the user can select the mode switching according to the application, it is possible to cope with various clothing fabrics without making holes, and convenience is improved.

  Moreover, the durability of the inner blade 30 can be improved by switching the rotation direction of the inner blade 30 and cutting the pills from both sides of the inner blade 30. Therefore, even if the hair ball remover 10 is used many times, it is difficult to damage the fabric and the hair ball can be removed.

  In addition, the hair ball remover 10 can also be provided with a ring-shaped dough guard 15 that can be attached to and detached from the head portion 13 as an accessory (see FIGS. 3 and 4). The cloth guard 15 can adjust the distance from the surface of the outer blade 31 to the cloth depending on the state of the cloth and the size of the hairball. By using the fabric card 15, it is possible to further prevent the fabric from being damaged.

(Specific configuration of hair ball remover )
Next, a specific configuration of the hair ball remover 10 for removing the hair ball while making it difficult to damage the fabric will be described with reference to FIGS. 5 to 10 together with FIGS. FIG. 5 is a schematic perspective view of the inner blade 30 (inner blade set) in a state attached to the connection tool 27. 6 and 7 are a schematic front view and a schematic back (bottom) view of the inner blade set, respectively. 8 and 9 are schematic side views of the inner blade set viewed from different directions. FIG. 10 is a view for explaining the bending angle of the edge portion 40a in the inner blade 30. FIG.

  The inner blade 30 attached to the connection tool 27 includes a plate-like blade portion 40 provided in a plane parallel to the axial direction (passing through the rotation center O) of the connection tool 27 in which the shaft tube 28 serves as a rotation axis. (See FIG. 6). The inner blade 30 has an edge portion 40 a on the inner surface side of the outer blade 31 in the blade portion 40. A plurality (three in this embodiment) of blade portions 40 in the inner blade 30 are provided at equal intervals in the circumferential direction so as to be radial (in the radial direction) from the rotation center O.

  Further, the inner blade 30 is configured such that the blade portion 40 has elasticity with respect to the inner surface of the outer blade 31 so that the edge portion 40 a contacts the inner surface of the outer blade 31. Specifically, the inner blade 30 has a plate-like arm portion 41 provided in a plane orthogonal to the axial direction of the rotation shaft (passing through the rotation center O). The arm portion 41 is provided separately from the rotation center O corresponding to the blade portion 40 (in this embodiment, three at equal intervals in the circumferential direction). And the blade part 40 is provided so that it may stand upright at the front-end | tip part of this arm part 41. As shown in FIG. The inner blade 30 is attached to the connection tool 27 by a fixing tool 42 in the middle part of the arm part 41 branched from the rotation center O side.

  In this embodiment, as shown in FIGS. 8 and 10, the inner blade 30 has an inner edge portion 40 a of the blade portion 40 in the direction parallel to the axial direction P of the rotation shaft (the length direction of the shaft tube 28). The blade 30 is bent in the counterclockwise direction B (forward rotation direction, other direction) opposite to the clockwise direction A (reverse rotation direction, one direction) in which the blade 30 rotates.

  Specifically, the edge portion 40a (tip portion) is bent at a bending angle θ from the portion of the blade portion 40 on the connection tool 27 side in a direction parallel to the axial direction P. According to FIG. 10, the blade portion 40 has a surface Sa on the clockwise direction A (reverse rotation direction) side and a surface Sb on the counterclockwise direction (forward rotation direction) B side, and the edge portion 40a is the surface Sa. It is bent so as to form a mountain fold on the side (a valley fold on the surface Sb side). That is, the bending angle θa of the surface Sa is larger than the bending angle θb of the surface Sb.

  For this reason, in the soft mode in which the inner blade 30 is rotated in the clockwise direction A (reverse rotation direction), the edge portion 40a having a large bending angle θa rotates so as to follow (lick the inner surface of the outer blade 31). It is possible to prevent the fabric from being bitten by the inner blade 30, and it is possible to remove the pills by making the fabric difficult to damage. On the other hand, in the normal mode in which the inner blade 30 is rotated in the counterclockwise direction B (forward rotation direction), the edge portion 40a having a small bending angle θb is rotated so as to precede (pierce the inner surface of the outer blade 31). For example, even a large pill can be easily removed. As described above, in the hair ball remover 10 according to this embodiment, the soft mode is a mode in which a load on the fabric is small and perforation is prevented with respect to the normal mode.

  In the present embodiment, the bending angle θ is 10 degrees, but the bending angle θ is preferably 5 degrees or more and 10 degrees or less. When the bending angle θ of the edge portion 40a is smaller than 5 degrees, the difference between the soft mode and the normal mode is decreased. When the bending angle θ of the edge portion 40a is larger than 10 degrees, the inner blade 30 is rotated in the clockwise direction A ( Even if it rotates in the reverse rotation direction), the reaping ability of the hairball is reduced. As described above, the mode can be properly used depending on the rotation direction of the inner blade 30. However, when the bending angle θ of the edge portion 40 is 5 degrees or more and 10 degrees or less, the function of each mode can be secured. it can.

  Moreover, in this embodiment, as shown in FIG. 8, the hair ball remover 10 protrudes from the installation surface 27a of the connection tool 27 and causes the blade portion 40 of the inner blade 30 to be in the counterclockwise direction B (forward rotation direction) side. The support part 43 supported from is provided. As described above, since the edge portion 40a is bent at the bending angle θ, when the inner blade 30 rotates in the clockwise direction A (reverse rotation direction), the edge portion 40a follows. For this reason, when the inner blade 30 rotates, the blade portion 40 is inclined too much, and there is a possibility that the hair cutting ability of the hairball is lowered. By providing the support portion 43 in this respect, it is possible to prevent the blade portion 40 from being excessively inclined when the inner blade 30 is rotated, and the hair cutting ability is reduced.

  Here, the support portion 43 includes an inner support portion 43a provided near the rotation center O (the rotation shaft 25, the shaft tube 28) and an outer support portion 43b provided far from the rotation center O, and the inner support portion. More preferably, the height of 43a is higher than the height of the outer support portion 43b. According to this, the blade portion 40 of the inner blade 30 on the rotation center O side is inclined by the rotation by increasing the height of the inner support portion 43a on the rotation center O side that is close to the fabric when removing the hairball. Therefore, it is possible to prevent the hairball cutting ability from being lowered.

  Moreover, in this embodiment, as shown in FIG. 7, FIG. 9, the connection tool 27 is a connection tool by which the axial cylinder 28 becomes a rotating shaft in the back surface on the opposite side to the installation surface 27a side in which the inner blade 30 is provided. 27 has a plate-like fan piece 29 provided in a plane parallel to 27 axial directions (passing through the rotation center O). That is, the connection tool 27 has a function as a fan. A plurality (three in the present embodiment) of fan pieces 29 are provided at equal intervals in the circumferential direction so as to be radial (in the radial direction) from the rotation center O.

  According to this, even if the connector 27 rotates in the clockwise direction A (reverse rotation direction) or in the counterclockwise direction B (forward rotation direction), the fan piece 29 is the same with respect to the rotation direction. It will rotate at an angle (90 degrees which is vertical). Therefore, in the head portion 13 where the connection tool 27 is provided, even if the connection tool 27 rotates in any direction, the generated air flow is directed to the dust container 14 side, and the pills cut from the fabric are removed. Release from the outer blade to the outside can be prevented.

  Although the present invention has been specifically described above based on the embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention.

  For example, in the said embodiment, the case where it applied to the hair ball remover provided with two modes (function) of soft mode and normal mode which become a standard of how to remove a hair ball depending on the state of the fabric and the size of the hair ball was described. . However, the present invention is not limited to this, and it can be applied to a hair ball remover having only a soft mode to make it difficult to damage the fabric and remove the hair ball.

  Further, for example, in the above-described embodiment, the case has been described in which the inner blade is rotated forward and backward by electrically switching the polarity of the motor. However, the present invention is not limited to this, and the inner cutter may be rotated forward and backward by a mechanical mechanism (switching of a plurality of gears).
