Description

The proposed device relates to devices for hair removal or hair removal, which can be held in the hand, and which is designed to remove unwanted hair on the human body, mainly in the area of inaccessible areas of the human face.

The prior art device for removing hair, consisting of a housing, an electric drive, a working element, which is a spiral spring, bent in the form of an arc with the possibility of rotation. To ensure the required rigidity, a wire is located inside the working element [SU 1228775, 1983].

The disadvantage of this device is the presence of a wire inside the coil spring, which provides excessive resistance to rotation of the working element and does not allow minimizing the size of the device in order to use it to remove hair in hard-to-reach areas of the person’s face with the ability to remove the shortest gun hairs.

Also known devices (trimmer) for removing hair from inaccessible parts of the face (nose, ears), consisting of a body, an electric drive, a battery, a nozzle containing a cutting head, consisting of a fixed knife fixed to the head cover, and a movable knife located inside a fixed knife [JP 2007044082, 2005; JP 2011200460, 2010]. The nozzle is removable and fixed on the trimmer body.

The disadvantages of these devices are, firstly, that the hair is removed by cutting, which is a less effective way compared to removing hair by pulling (hair removal) and, secondly, that a fixed knife having a certain thickness does not the possibility of removing hair shorter than the thickness of this knife.

Closest to the proposed technical solution is a device containing a housing, an electric drive, a battery, a working element, which is a spiral spring, bent in the form of an arc. Hair removal is carried out by capturing the hair with a spiral spring rotating around an axis [CN 1606940, A45D 26/00, 2003].

The disadvantage of this device is that it is not intended to remove hair from the inaccessible and embossed surface of a person's face (nose, auricles, etc.). The diameter of the spring is 3-8 mm and does not allow you to get the size of the working element necessary to ensure its access to such places and even more so able to remove short gun hairs, this requires miniaturization of the device. In this case, with the minimum diameter of the spring and the length necessary for its functioning, when there are loads on the spring at the time of hair removal, there is a chance of twisting and blocking the operation of the device.

The technical objective of the proposal is to eliminate the above drawbacks and develop a device designed to remove unwanted hair from hard-to-reach parts of a person’s face (nose, auricle, upper lip, eyebrow line) by pulling (hair removal), while ensuring capture, including the shortest fluffy hair with minimal pain.

The problem is solved using a device for removing hair, or an epilator, mainly from hard-to-reach areas of a person’s face, containing a housing in which the drive is installed, a rotatable working element, which is a spiral spring bent in the form of an arc, while the arcuate section of the spring is located outside the housing, and one end of the spring is connected to the actuator, and it contains guides for the spring, made in the form of bushings or in the form of a system of interconnected rings, nye in the upper part of the body.

The technical result, the achievement of which this technical solution is directed, is the ability to remove, including the shortest gun hair, mainly in hard-to-reach parts of a person’s face with minimal pain.

An essential distinguishing feature of the proposed device for removing hair from the above known, closest to it, is the presence of guides for the spring made in the form of bushings or a system of interconnected rings installed in the upper part of the body. The guides increase the stability of the device, ensure the rigidity of the working element and prevent the spring from twisting with a minimum spring diameter and the length necessary for its functioning to obtain a device for removing unwanted hair in hard-to-reach areas of a person’s face by pulling (epilation), including the shortest cannon hairs.

The proposed device for hair removal is illustrated by the drawings shown in FIG. 1-5:

in FIG. 1 - shows a General view of the device in vertical section (integral design);

in FIG. 2 - a fragment of a spring with guides in the form of a system of rings on an enlarged scale;

in FIG. 3 is a general view of a device with a detachable nozzle (modular design) in a disassembled state (in vertical section);

in FIG. 4 - a fragment of the working element (spring) with turns in the form of a linear section (with straightened turns) on an enlarged scale;

in FIG. 5 is a fragment of a working element with a miniature eccentric weight on an enlarged scale.

This hair removal device has two options, it can be either a one-piece, non-separable design, or a modular design.

In the first embodiment (one-piece construction), the hair removal device (epilator) (Fig. 1) is a body 1 for holding in the hand, in the lower part of which there is an electric drive 2 with a power element 3, a switch 4. In the upper part there is a working element 5, designed to remove hair by pulling (hair removal), guides 6, attachment 7. Working element 5 is a coil spring made of wire twisted by turns. The spring has the shape of an arc, one end of which is attached directly to the shaft 8 of the electric drive 2, and the second end is fixed in the upper part of the housing 1 in the mount 7 by means of a rolling or sliding bearing (not shown in the drawing), or in another way that rotates the working element 5 The arcuate portion of the spring 5 is located outside the housing 1.

The guides 6 are made in the form of bushes of preferably circular cross-section and can have a different configuration for the output of the ends of the working element to the fixation points with the mount 7 and the shaft 8 of the electric drive 2. To reduce the contact area of the spring with the guides, the guides 6 can also be implemented as a system connected between rings (Fig. 2), forming a cavity of the required size and configuration to accommodate the working element 5.

The upper part of the housing 1, the guides 6 and the mount 7 are made primarily of plastic by injection molding and can be a single unit or separate parts.

The operation of the device is as follows. When you turn on the device by means of the switch 4, the rotation from the electric drive 2 is transmitted to the working element 5, represented by a spiral spring, twisted by turns, bent in the form of an arc.

To remove unwanted hair, the arcuate part of the spring 5, located outside the upper part of the housing 1, is carried out on the corresponding section of the skin.

When the working element 5 rotates around its axis, the hair is captured by the coil of spring in the gap between adjacent coil of spring, formed on the outer side of the spring in the place of its bend, clamped by convergent coils on the inner side of the bend of the spring and pulled out by a rotating spring.

The second version of the epilator is implemented as a modular collapsible design with the ability to separate the upper part and use it as a replaceable nozzle (Fig. 3). Nozzles of this type can also be used with the aforementioned trimming trimmers that are currently manufactured as an additional nozzle for an alternative method of removing hair. The proposed device includes a housing, which in height consists of two parts: the lower part of the housing 1 for holding in hand, containing an electric drive 2 with a battery 3, a switch 4 and attached to the lower part of the housing 1 with a removable nozzle 9. Removable the nozzle 9 contains a working element 5, a mounting unit 7 and guides for the spring 6 and is fixed on the mounting pad 11 of the lower part of the device.

The working element 5, as in the first embodiment, is a coil spring made of wire twisted by turns, having the shape of an arc passing inside the guides 6. One end of the spring is fixed inside the nozzle 9 in the mount 7 by means of a rolling or sliding bearing (not shown in the drawing) or in any other way, providing rotation of the working element. The arcuate section of the spring 5 is located outside the nozzle 9. At the second end of the spring, also located inside the nozzle 9, a tip 12 is fixed, in the lower part of which there is a hole 13 into which the tip 10 of the shaft 8 of the electric drive 2 is inserted to ensure the engagement and transmission of rotational movement. The guides 6 are fixed inside the nozzle 9.

The guides 6 are made in the form of bushings of preferably circular cross section and can have a different configuration for the output of the ends of the working element to the fixing points with the attachment unit 7 and the tip 10 of the shaft 8 of the drive 2. The guides 6 can also be implemented as a system of interconnected rings (FIG. 2) forming a cavity of the required size and configuration for placement of the working element 5 in it.

The nozzle 9, the guides 6 and the mount 7 are made primarily of plastic by injection molding and can be either a single unit or separate parts.

In the case of a modular design, when fixing the nozzle 9 on the mounting pad 11 of the lower part of the housing 1, the tip 10 of the shaft 8 of the electric drive 2 is inserted into the hole 13 and engages with the tip 12 of the working element 5 of the replaceable nozzle 9. When the device is turned on by the switch 4, the rotation from the electric the actuator 2 is transmitted to the spring 5. Further, the device according to the second embodiment works similarly to that described above.

The length of hair to be removed depends on the thickness of the wire from which the spring is made, so the diameter of the spring wire is minimal in order to capture even the shortest gun hairs and penetrate into the most inaccessible areas of the face. For example, a working element 5 made of wire with a diameter of 0.2 mm allows you to remove hair with a length of 0.15 mm, which allows you to use the device to remove unwanted hair from areas of the face such as the eyebrow line or upper lip (mainly in women) where the presence of even very short hair can be noticeable.

The minimum diameter of the wire of which the spring is made, as well as the minimum diameter of the spring of which the working element is made, allow the spring to be bent with a much smaller radius, which minimizes the size of the working (arcuate) section of the spring. This allows you to use the epilator also for the correction of the eyebrow line, which known devices for hair removal do not allow.

The wire for the manufacture of the spring is made of steel or another material that provides the necessary mechanical characteristics.

For more effective hair removal, the working element (spring) 5 may have a special coating, for example polyvinyl chloride (PVC). Compared to steel, the material is softer and more flexible, the PVC coating provides a tighter fit of the coil of the spring at the points of contact with each other, and also increases the contact area, which ensures the capture of more removed hair. A higher sliding friction coefficient than steel improves hair grip and reduces hair slippage between the turns of the spring at the time of pulling out.

To achieve an analgesic effect, one or more turns on the arcuate section of the coil spring can be made in the form of a linear section (Fig. 4), which gives the spring oscillatory movements during rotation. As a result, when a vibrating spring comes in contact with the skin, the nerve endings of the skin are stimulated, which reduces pain during epilation. Also, to give the spring oscillatory movements during rotation around its own axis, a miniature eccentric weight can be fixed on one of the turns of the arcuate section (Fig. 5).

Thus, the technical result when using this device is expressed in the possibility of effective removal, including the shortest fluffy hair, mainly in such inaccessible parts of the face as the nose, auricle, with minimal pain, and the proposed device for removing hair is reliable and convenient to use.
