Abstract

PURPOSE:To surely execute the discharge of a hair trash to a hair trash housing room by inclining the internal blade side edge of the blade of a fan to feed the hair trash to the hair trash housing room towards a fan rotating direction front side, and simultaneously, providing an opening to cause the hair trash housing room and an internal blade housing room to communicate in the radius direction part of the fan. CONSTITUTION:An internal blade housing room 13 is made to communicate through an opening 71 formed on a circumferential surface at a bottom plate 70 side of a fitting base 7 and an opening 17 formed on the outer circumferential surface of a head part 11 of a main body 1 to a hair trash housing room 20 in a dust case 2. The edge of the internal blade side of each fan blade 53 of a fan 52 is made into an inclined piece 54 inclined towards the rotating direction front side of the fan 52. Since the inclined piece 54 generates the smooth flow of a wind to feed the air trash between the fan blades 53, the counterflow of the hair trash cannot be caused, the air trash flows along the blade 53 surface in an outer circumferential direction, and it is surely fed through the opening 71 located in the radius direction of the fan to the hair trash housing room 20.

Description

[Detailed description of the invention] [Industrial application field]

The present invention is directed to a hair cutting device that is equipped with an outer blade in which a large number of hair introduction holes are formed and an inner blade that comes into sliding contact with the inner surface of the outer blade, that is, an electric razor, a hair cutter, a sweater or a sock. , relates to a hair cutting device such as a pill remover for removing pilling formed on clothing such as tights, blankets, etc.

[Conventional technology]

Some hair cutting devices of this type are equipped with a fan that sends cut hair waste toward a hair waste storage chamber. For example, in the electric shaver shown in Japanese Utility Model Application No. 48-12087, as shown in FIG.
A 7T tongue 52 which is also rotationally driven by the motor 5 is disposed, and an open lower lower 1 leading to the hair waste storage chamber 20 is further provided on the bottom surface of the inner cutter storage chamber 13. As shown in FIGS. 15 and 16, the 7-an 52 here has rod-shaped blades that protrude radially, and one side of each blade is an inclined surface, so that the hair waste accumulated at the bottom of the inner cutter storage chamber 13 can be removed. Sweep it out toward the opening lower 1.

[Problem N that the invention attempts to solve]

In this case, as shown in FIG. 17, when the wind flow along each blade is divided into two parts: one along the inclined surface and the other along the surface of the blade on the inner blade 42 side. The wind flowing along the side surface does not contribute to sending the hair chips to the back, but instead encourages the hair chips to flow back toward the inner blade 42, and as shown in FIG. 18, The hair debris flowing along the slope of each blade surface is pressed against the bottom surface of the inner blade storage chamber 13 in which an opening is formed in a part,
There is a problem in that the hair is not sent to the hair waste storage chamber 20 and accumulates here. The present invention has been made in view of these points, and its object is to provide a hair cutting device that can reliably discharge hair waste into a hair waste storage chamber.

[Means to solve the problem]

Therefore, the present invention includes an outer cutter in which a large number of cutter holes for introducing bristles are formed, an inner cutter that slides into contact with the inner surface of the outer cutter, and a bristles inside the inner cutter storage chamber in which the inner cutter is stored. A hair cutting machine equipped with a fan that sends the waste to the hair waste storage chamber.
In this case, the end of each fan blade on the inner blade side of the fan is inclined toward the front in the rotational direction of the 7T, and the opening that communicates the hair waste storage chamber with the inner blade storage chamber is connected to the inner blade side of the fan. It is characterized by being provided in the radial direction. [Function] According to the present invention, the inclined piece on the inner blade side of the fan blade creates a smooth flow of wind that sends the hair waste between 7 tons, and the hair waste that has reached 7T blade darkness is removed from the fan blade. The hair flows along the surface toward the outer circumference, passes through the opening, and is fed into the hair waste storage chamber. [Example 1] The present invention will be described below in detail based on an example of the pill remover shown in the drawings. Dust case 2 which is said to be removable on the front of 12
The main body 1 is formed of a hauzong divided into left and right halves, and the rear peripheral surface of a cylindrical head part 11 has an outer cutter 41 at its tip, which is equipped with a number of blade holes for introducing hair. , one end of the grip portion 12 is connected. The main body 1 houses the motor 5 in the head part 11 and the power supply part 6 in the grip part 12, and has a cylindrical mounting base 7 housed in the head part 11. The frame 4 of the outer cutter 7 is mounted in a rectangular cylinder section 73 provided on the back side of the bottom plate 70 of the stand 7, and the outer cutter 7 frame 4 provided with the outer cutter 41 is detachably attached to the opening at the tip of the mounting stand 7. The space surrounded by the mount 7 between the bottom plate 70 and the outer cutter 41 in the mount 7 is attached to the output shaft of the motor 5 via the joint 51 and the inner cutter base 43, and the outer cutter 41 is attached to the output shaft of the motor 5 via the joint 51 and the inner cutter base 43. An inner cutter storage chamber 13 is configured to accommodate an inner cutter 42 that rotates and slides on the inner surface. This inner blade storage chamber 13 is comprised of an open lower 1 formed on the bottom plate 70 side surface of the mounting base 7 and a head 851 of the main body 1.
It is connected to a hair waste storage chamber 20 in the dust case 2 through an opening 17 formed on the outer peripheral surface of the dust case 2 . The mounting base 7 is fixed to the main body 1 by screws that are inserted into the bottom plate 70 from the front side and screwed into the main body 1. At this time, an annular rib 72 protruding from the peripheral back side of the bottom plate 70 This pill remover 9 fits into the groove formed inside the main body 1 and prevents hair from entering the motor 5 side. There are two types of power supply unit 6 and an AC type power supply unit 6 equipped with a connector to be connected to a commercial power source as shown in Fig. 5. Depending on the difference in the power supply unit 6, the motor 5 is also a DC type. A direct current motor and an alternating current motor are used, but a direct current motor5
As shown in FIG.
1 is fixed with ribs 92 on the inner surface of the main body 1, and the AC motor 5 is placed directly inside the main body 1 without attaching the mounting frame 91, and is fixed with screws from the front side of the bottom plate 70 of the mounting base 7. It is assumed that As is clear from Figure 5, the front of the grip ff612 is as follows:
The mounting space for the dust case 2 is thick (a mounting base 14 is provided by a cutout, and four sides 15 extending to both sides of the mounting base 14 are provided in a part of the mounting base 14, and a mounting base A plurality of locking recesses 16 are provided on both sides of the dust case 14. On the other hand, as shown in FIG. It is attached to the main body 1 by engaging the plurality of locking protrusions 21 provided on the back side with the locking recesses 16. At this time, By overlapping the stepped portion 24 formed at the opening of the dust case 2 with the recessed step 91B formed on the main body 1, hair debris is prevented from falling from the opening of the dust case 2, and the dust case 2 As shown in FIG. 3, the ribs 23 protruding from the rear side portions of both sides of the dust case 2 protrude from both sides of the grip n12 of the main body 1, and serve as a handhold when removing the dust case 2 from the main body 1. Now, the dust case 2 attached to the main body 1 in this manner communicates its internal space, the hair waste storage chamber 20, with the inner blade storage chamber 13 through the opening 17.71, as described above. An inner cutter 4 that rotates and slides into contact with the inner surface of the outer cutter 41
2, the cut hair waste is sent to the hair waste storage chamber 20 through the open lower part 1.17 by the rotary driven 7-un 52.
sent inside. Of the inner walls of the double-opening lower 1.17, the rear inner wall has inclinations a and β, as shown in Figure 1, and for this reason, the double-opening lower 1.17 has a dust case. 2@ has a larger cross-sectional area. Next, the 7-an 52 will be explained. This 7-ring 52 connects the inner cutter base 43 on which the inner cutter 42 is mounted and the motor 5, and as shown in FIG. The joint 51 is provided with a modified cross-section portion 58 that engages with the inner cutter base 43 in the middle,
It is provided by forming a plurality of fan blades 53 radially and integrally, and the end of each fan blade 53 on the inner blade 41 side is rotated by the rotation of the 7-ring 52 shown by the arrow in the figure. The slanted piece 54 is slanted toward the front side, and a rib 55 is formed on the green of the inner blade 42@ of this slanted piece 54, and the rib 55 projects in the direction of rotation.
Furthermore, a rib 56 is formed on the edge of the inclined piece 54 so as to protrude in the direction of rotation. Note that the ribs 56 are also inclined with respect to the axial direction of the joint 51. In the figure, 8 is a comb attached to the outer circumferential surface of the mounting base 7 so that it can slide in the axial direction, and 9 is a power switch. Reference numeral 90 in FIG. 1 is the switch body.゛However, when the hair introduced through the blade hole of the outer blade 41 is cut by the rotationally driven inner blade 42 and the edge of the blade hole of the outer blade 41, the fan 52 is also rotating at the same time. Hair waste (in this case, hairballs) generated by cutting is removed by the wind along the front and back surfaces of the fan blade 53, which is generated by the fan blade 53 having the inclined piece 54, and is moved to the inner blade storage chamber as shown in FIG. 13, enters between the fan blades 53, and is sent out along the surface of the fan blade 53 to the outer circumferential side, passing through the open lower lowers 1, 17,
The hair is sent to the hair waste storage chamber 20 of the dust case 2. 7
The air sent into the dust case 2 by the air vent 52 flows out from the exhaust hole 22 through the gap between the four sides 15 of the main body 1 and the back surface of the guest case 2. At this time, the rib 55 provided on the inclined piece 54 of the fan blade 53 is
A rib 56 formed on the edge of the inclined piece 54 is shown in FIG. As shown, the inner blade storage chamber 13 is provided with a smooth curved surface 75 at the inner corner to prevent hair from spilling out to the outer periphery at the portion of the fan blade 53 that does not face the opening lower 1. Therefore, the hair debris flows smoothly to the open lower part 1 as shown by the arrow in Fig. 11.
The rotation of the fan 52 is not obstructed by hair debris accumulating in the corners. The fan blade 53 may have a cross-sectional shape as shown in FIG. 12, that is, a piece of the bottom plate 70Ill may also be inclined toward the front in the rotational direction. However, it is assumed that the angle of inclination is smaller than that of the inclined piece 54. In this case, the flow of air flowing along the fan blade 53 becomes smoother, and the force for sucking in hair becomes stronger. As shown in FIG. 13, the fan blade 52 may have a centrifugal fan shape, provided that each fan blade 53 has at least a portion on the inner blade 42 side inclined forward in the rotational direction. Keep it as a thing.

【Effect of the invention】

As described above, in the present invention, the inclined piece on the inner blade side of the fan blade creates a smooth flow of air that sends hair waste between the seven unbraids, and does not cause backflow of hair waste. The hair that has arrived between the fan blades flows toward the outer circumference along the surface of the rotating fan blade, and is reliably sent into the hair storage chamber through the opening located in the radial direction of the fan. .
