Description

The utility model relates to manicure and pedicure accessories, namely to electromechanical devices for hardware manicure and pedicure, the so-called milling cutters, which use removable nozzles or milling cutters for grinding both the nail itself and the skin around it. The design of such nozzles or mills also relates to the claimed utility model.

There are many similar nozzles that are used to cut dead or hardened tissue from the surface of human skin, among which the closest are the following.

Known nozzle for an apparatus for removing dead or hardened tissue from the surface of human skin, described in US patent 3, 468,079, published 23.09.1969. The nozzle contains a disk with an external working surface and its reverse surface, to which a rod is attached for attaching the nozzle to the apparatus for manicure and pedicure. The rod is attached to the back surface of the disc using a bolted connection. The work surface is suitable for connection with a pad that has an abrasive outer surface. The disk has openings arranged in pairs diametrically opposite to each other. The holes are made in the form of a bucket, which protrudes from the side opposite to the surface of the disk, which is due to the air intake functions of the holes. A nozzle of this design prevents clogging of the cutting edges with the cut fabric and cooling of the working surface with air. However, the disadvantage is a slight decrease in the quality of the surface treatment of the skin, which is due to the shape, design and location of the holes, as well as the relatively complex technology of making holes due to their bucket-like shape.

As a prototype, a nozzle for an apparatus for manicure and pedicure was selected, which is described in patent RU 190 550 U1, published on July 3, 2019. The nozzle according to the prototype contains a disk with an external working surface and its reverse surface, to which a rod is attached for attaching the nozzle to the apparatus for manicure and pedicure. Through holes are made in the disk, arranged in pairs diametrically opposite to each other. An example implementation of the nozzle according to the prototype describes round holes. The working surface of the disc is also suitable for working with abrasive pads. The nozzle according to the prototype allows to reduce the mass of the disk and increase cooling of its surface due to air circulation through the holes. The holes also improve the convenience of removing used abrasive pads by pressing through them on the surface of the pads. However, studies have shown that regulating the volume of accumulated cut tissue and increasing the efficiency of its accumulation, as well as improving the performance of the apparatus for manicure and pedicure in which the nozzle is used, depends on the shape of the holes. For example, it was found that round holes do not allow you to effectively control the amount of accumulated cut tissue and its accumulation, as well as improve the operational characteristics of the apparatus for manicure and pedicure.

Therefore, the utility model was based on the task of developing a nozzle design for a manicure and pedicure apparatus, the use of which increases the efficiency of regulating the volume of cut tissue and its accumulation, as well as improves the performance of the manicure and pedicure apparatus by determining the shape of the holes, which allows optimizing the weight of the disc and the cumulative functions of the holes when cutting tissue.

The problem is solved in such a way that in the known nozzle for the apparatus for manicure and pedicure, which contains a disk with an external working surface and its reverse surface, to which a rod is attached for attaching the nozzle to the apparatus for manicure and pedicure, through holes are made in the disk, located pairwise diametrically opposite to each other, according to a utility model, the holes have an asymmetric elongated shape formed by a circle of a larger diameter and a circle of a smaller diameter, connected tangent to both circles straight, and the holes are made so that the circle of larger diameter is closer to the periphery of the disk, while the number of holes is a multiple of two, but not less than four.

The technical result from the through holes in the disk is to increase the efficiency of removal of cut tissue from the cutting zone under the action of centrifugal forces resulting from the rotation of the nozzle during operation of the apparatus. At the same time, openings of this shape in the disk act as a reservoir for the accumulation of cut off dead or hardened tissue of the nail and the skin around it. The volume of the truncated tissue decreases or increases in direct proportion to the decrease or increase in the diameter of the disk, which determines the shape of the holes and their location in pairs diametrically opposite to each other, in the number of holes a multiple of two, but not less than four. The size of the holes affects the weight of the nozzle, which in turn affects the operational characteristics of the apparatus for manicure and pedicure, the executive (working) element of which is the claimed nozzle.

According to one preferred embodiment of the nozzle, the holes in the disk can be located radially on mutually perpendicular axes of symmetry of the disk, which further increases the efficiency of regulating the volume of accumulated cut tissue and its accumulation due to the symmetrical arrangement of the holes and more uniform rotation of the disk.

According to another preferred embodiment of the nozzle, the disk may have a flat working surface, which simplifies the manufacture of the nozzle.

According to another preferred embodiment of the nozzle, the disk may have a spherical working surface. The use of a spherical shape of the working surface of the disk increases the efficiency of using the abrasive material of the lining located on the working surface of the disk, or the working surface made abrasive, due to the fact that during the processing the entire cutting surface can be used in turn or its significantly larger spherical part of the surface compared with the nozzle with a flat working surface of the disk, which in turn increases the life of the cutting (grinding) part and, as a result, uve ichivaet speed and quality of processing. In this case, the spherical shape of the working surface in comparison with the flat shape of the disk prevents the sharp cutting of the ends (edges) of the disk into the processed material (nail or fabric around it), which protects the person from unforeseen injuries.

According to another preferred embodiment of the nozzle, the working surface of the disk can be minimally partially abrasive, which allows more efficient removal of waste material from the cutting zone due to the presence of gaps between the cavities under the action of centrifugal forces resulting from rotation of the nozzle disk, and also use the nozzle without the use of abrasive pads.

The following is an example of a nozzle and its operation with a manicure and pedicure apparatus, illustrated by the following images: FIG. 1 is a general view of the nozzle, FIG. 2 is a front view of the nozzle, FIG. 3 is a side view of the nozzle. The given examples and the provided images do not limit other possible options for the nozzle according to the utility model, but only explain its essence and confirm the possibility of its implementation.

In FIG. 1-3 the following notation is used:

1 - disk

2 - the working surface of the disk,

3 - the reverse surface of the disk,

4 - rod

5 - shoulder

6 - through holes,

7 - a circle of larger diameter,

8 - circle of smaller diameter,

9 - straight lines connecting a circle of a larger diameter and a circle of a smaller diameter of a through hole,

10 - the periphery of the disk.

The nozzle for apparatus for manicure and pedicure contains a disk (1) with a flat external working surface (2) and its reverse surface (3). A rod (4) is attached to the back surface (3) for attaching the nozzle to the apparatus for manicure and pedicure (the apparatus is not shown in the figures). For this, the apparatus is equipped with a collet and a rod clamp. In the place of attachment of the rod (4) to the reverse surface (3), a mounting collar (5) is made. The presence of the mounting collar (5) allows you to accurately position the nozzle inserted into the apparatus for manicure and pedicure, and to prevent a possible violation of the fixation of the nozzle relative to the apparatus or its incorrect installation and operation, in particular, the occurrence of runout of the disk (1) during rotation at maximum speed. Through holes (6) are made in the disk (1). The holes (6) are arranged in pairs diametrically opposite to each other. The number of holes (6) is a multiple of two, but not less than four. The holes (6) have an asymmetric elongated shape formed by a circle of a larger diameter (7) and a circle of a smaller diameter (8). The circles (7) and (8) are connected by straight lines (9) tangent to both circles. The holes (6) are arranged so that a circle of a larger diameter (7) is located closer to the periphery of the disk (10). The holes (6) are located radially on mutually perpendicular axes of symmetry of the disk (1).

Alternatively, the disk (1) may have a spherical working surface (2). Also, the working surface (2) can at least partially be made abrasive, for example, with protrusions (not shown in the figures).

Use the nozzle of the construction described above mainly with removable overlays (files), which are connected to the working surface (2) of the disk (1) using the adhesive surface of the lining, for example, double-sided tape or glue - a substance or a multicomponent composition based on organic or inorganic substances. The interchangeable pad has an external abrasive surface opposite the adhesive surface. The adhesive surface is protected by a removable liner prior to use. Also, the interchangeable pad has holes that match the through holes (6) in the disk (1).

To carry out manicure or pedicure, the rod (4) with a removable pad glued to the working surface (2) of the disk (1) is fixed in the collet of the manicure and pedicure apparatus using the mounting collar (5) and fixed with a clamp. Then the apparatus is turned on, after which the collet begins to rotate together with the rod (4) and the disk (1). By contacting the disk (1) and a variable lining with an abrasive surface rotating with the disk (1), dead or hardened tissue is removed from the nail or skin in the area of the human nail. The speed of rotation of the disk (1) can be controlled by the apparatus. When developing the abrasive surface of the abrasive lining, it is separated from the working surface (2) and replaced with another lining.

Industrial applicability. The disk (1) and the shaft (4) can be made of alloy material, which greatly facilitates the weight, and, in turn, makes it possible to increase the speed of the apparatus for manicure and pedicure and thereby accelerate the speed and quality of processing. It is also advisable to manufacture at least a disk (1) from an alkaline-acid-resistant material, which significantly increases the sanitary and hygienic characteristics of the nozzle. An example of such a material is corrosion-resistant steel grade 08X18H10, 07X16H6 or analogs AISI 304, AISI 301. The disk (1) and the rod (4) can be joined by an integral connection, for example, such as laser welding. Laser welding improves the reliability of the connection of these parts of the nozzle and prevents the twisting or breakage of the nozzle when the device is operating at high speeds, thereby increasing the safety of manicure or pedicure.

The geometric dimensions of the discs (1) may be different, preferred are the discs (1) with a diameter of 15 mm or 20 mm or 25 mm. The length of the shaft (4) is preferably 30 mm for discs of different sizes. The dimensions of the variable abrasive pads should be slightly smaller than the diameter of the discs (1) to prevent the protrusion of the pads beyond the discs in order to avoid causing a cutting wound when the disc (1) rotates.

The claimed utility model allows to increase the efficiency of regulating the volume of accumulated cut tissue and its accumulation, as well as improve the operational characteristics of the apparatus for manicure and pedicure.
