Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a hair cutting device for cutting hair balls generated on the surface of hair or fabrics such as clothing.

[Conventional technology 1] Conventionally, a hair cutting device that cuts hair by sliding a comb-like blade on the head includes a hair cutter for scalp hair and a hair cutter for removing pilling from the fabric of clothing. There are ball removers, etc. When cutting hair into short lengths with this hair cutting device, it is necessary to reduce the thickness of the lower blade, and the tip of the blade is open to improve the introduction of the hair. However, if the tip of the blade is open, it has the drawback of damaging the scalp or catching fabric when cutting hair, and for this reason, a hair cutting device as shown in Publication of Utility Model Publication No. 48189 of 1982 was provided. . This lower blade 1a has an open tip, and the tip is whitened upward to prevent hair from getting caught when cutting hair.

[Problems to be solved by the invention] However, in the conventional example as described above, since the tip of the lower blade 1a is bent, the tip of the lower blade 1a becomes longer and its strength decreases. There was a problem that when cutting hair, the blade deforms and gets caught in the upper blade 1b, or a large load is applied to it, reducing the cutting quality. In addition, due to its low strength, it was often deformed by pressing when cutting the hair or by falling rings.

The present invention is an attempt to solve the above problems, and its purpose is to provide a hair cutting device that is safe and can be moved smoothly and forwardly without getting caught.

[Means for Solving the Problems] In order to achieve the above object, the hair cutting device of the present invention is designed to cut hair by bringing a pair of tubular blades into sliding contact and reciprocating at least one of the blades. The tip of the horizontal lower blade 1a of the formed cutter portion 1 is bent upward, and the tips of the blade grooves IC adjacent to each other above are connected via a connecting portion 1d.

[Action 1] By bending the tip of the lower blade 1a upward and connecting the tips of the upper adjacent blade grooves IC via the connecting part 1d, the hair can be smoothly removed without damaging the fabric S or the skin. The cutting device can be moved straight and the lower blade 1a
The strength of the tip can be improved, and deformation due to pressing or falling can be prevented.

[Example 1] Hereinafter, a hair cutting device for cutting hair balls generated on the surface of fabrics such as clothing will be described in detail.

A drive unit 2 is provided in the housing 6 to reciprocate an upper blade 1b, which is a movable blade of the cutter part 1, via a joint 7. This upper blade 1b is connected to a motor 2b via an eccentric cam 2a. There is. As shown in FIGS. 4 and 5, the cutter section 1 includes a lower blade 1a, which is a fixed blade having a comb-shaped cutting edge 1a' fixed to a base 8, and a joint 7 that slides in reciprocating contact with the lower blade 1a. and an upper blade 1b having a comb-shaped cutting blade 1b' fixed thereto. The lower blade 1a has its tip bent upward at an obtuse angle, and the tips of a plurality of adjacent blade grooves 1c for introducing hair are connected via a connecting portion 1d.

The lower blade 1a is placed on a base 8, the upper blade 1b is placed on the upper surface of the lower blade 1a so as to be able to slide freely, and the upper blade 1b and the lower blade 1a are held together by a holding spring 16 via a joint 7. It is fixed to the base 8.

A pill suction passage 5 is formed above the front end of the blade part 1 to store the hair H cut by the blade part 1 in the pill storage part 3. Lower blade 1a
A hair raising space 20 is formed in the lower part of the hair ball storage section 3, which is made up of a storage case 3a, a case cover 3b to which a breathable filter 9 is fixed for suction, and an elastic valve 10 for preventing backflow. It is arranged above the cutter part 1 and in parallel with the drive part 2.

A drive section 2 and a pill suction means 4 are provided at the rear of the cutter section 1 and the pill storage section 3, and the pill suction means 4 is composed of a seven-ring 4a and a motor 4b for driving it. . Also, at the rear there is a power cord 1], a switch 12, and an electric control section 1.
3 to constitute the handle portion 14. 15 is an attachment for increasing the suction effect and supporting the fabric S.

The storage case 3a is transparent so that the storage state of the hair H can be visually checked.

Next, an example of the electric control section 13 will be explained using a circuit diagram shown in IJS6.

Normally, when the switch 12 is in the OFF state shown in FIG. 6(a), no current is applied and the motors 2b and 4b do not operate.When the switch 12 is in the OFF state shown in FIG. 3(c), the motors 2b and 4b are energized. When the motor 2b operates, the motor 4b operates, and the blade part 1 is operated, and the blade part 1 cuts the hair 1 while sucking by the seventh ann 4a, so that the hair H can be quickly removed. 19 is a fuse.

When using the hair cutting device, hold the handle part 14 in your hand as shown in FIG. Cut H. In other words, as shown in Figure 3, the fabric S
Hair H generated on the surface of the blade and falling down is raised in the hair raising space 20 by upward suction from the hair ball suction passage 5 formed in the front of the blade part 1 with approximately the same width as the blade width, Blade groove I
After being introduced into C, the raised bristles of the bristles H become the blade part 1.
The hair is then cut by suction and collected into the hair ball storage section 3 via the hair ball suction passage 5. At this time, since the hair is sucked upward through the hair ball suction passage 5, the hair 1 is easily raised in the hair raising space 20, and the hair H is introduced into the blade groove IC in the raised state. Knife part 1 for cutting the foot part
There is less load on the blade, and even with a small blade groove IC, the hair H
can be cut.
