Definitions

  • the invention relates to the field of cosmetics, namely to a portable hand-held device for coating in the form of velvet, velor or similar fleecy coatings, especially on areas of the surface of the human body, for example, on nails, for cosmetic purposes.
  • the material for applying such coatings is flock, that is, a mass of non-oriented cut fibers, which are obtained from raw materials of various origins (wool, cotton, polyamide, viscose, acrylic, etc.). They come in different lengths, different colors and different thicknesses. Coating from the flock is called flocking. Typically, such coatings are applied in an electrostatic field. A device for applying such a coating in an electrostatic field is called a flocator.
  • the principle of operation of the flocator is to orient the polarized, i.e. having an electric dipole moment, the flock fibers under the action of the electrostatic field in which they move, and gluing their ends to the adhesive surface, which is perpendicular to the field lines of force.
  • An electrostatic field is created by two electrodes spaced apart in space, between which a high voltage voltage is supplied.
  • the flock is located in the area of the first electrode in a container in which the fibers, when creating an electrostatic field, are electrified and polarized, and during movement they are oriented and move along its lines of force in the direction of the second electrode, which is placed in contact with the surface to be processed or being this surface.
  • the electrostatic field strength should be constant during the coating time.
  • the disadvantage of this device is its complexity, which leads to high cost, uncertainty and uncontrollability of the voltage generated by the generator, which can be quite large and therefore dangerous, and low reliability due to the presence of parts and assemblies that move, rub and rotate.
  • the basis of the invention is the task of creating a safer, simpler and more reliable portable manual flocator for applying a pile coating to a specific area of the surface of the human body.
  • the problem is solved in that in a portable hand-held device for applying a pile coating on the surface area of the human body, which includes a casing in the form of a rod of dielectric material with a flock container, a high-voltage voltage source, a means of manual control of the high-voltage voltage source, and high-voltage, located inside the casing the contact of the high-voltage voltage source is electrically connected to the electrode located inside the container, the container has an outlet, closed by a permeable to the flock grid of dielectric material, according to the invention, the high-voltage voltage source is configured to generate a number of high-voltage pulses during the coating time.
  • the device (flocator) needs to be shaken from time to time, and at the moment of shaking, the flock exit from the flocator is greatest, but subsequently it decreases to almost zero. It was experimentally established that the time of coating a certain surface, for example, of a nail, practically depends not so much on the time function of the electrostatic field as on the frequency of shaking the flock. Thus, the generation of several unipolar high voltage pulses during the coating time reduces the total duration of the electrostatic field and thereby increases the safety of the device.
  • the generation of unipolar high-voltage pulses provides electrification and polarization of the fibers in the container during the action of at least the first pulse and a sufficient interaction of charged and polarized fibers not only during movement from the container to the surface to be coated, but also after reaching the surface. That is, even if the fiber reached the surface in the absence of an electrostatic field and is not yet glued to the adhesive surface, it is able to be located along the force field lines and stick in this position into the adhesive surface.
  • first flock fibers when they reach the surface to be coated, be exposed to an electrostatic field in order to adhere perpendicular to the surface. Then, for the most part, other fibers will somehow pass between them, or orient themselves accordingly in the field, even if they lay down, but did not stick.
  • An important advantage of the invention is the ability to reduce high voltage when the flocator is located vertically above the surface to be coated (namely, this arrangement is assumed based on the purpose of the device according to the invention), since the fibers move down towards the surface under the influence of gravity, and therefore the role of the electrostatic field is reduced only to fiber orientation, which requires significantly less field strength than for movement, for example, in the horizontal direction or up.
  • the distance between the electrodes is 5 10 cm, this requires a voltage of not more than 10 kV. Therefore, this is another source of improving the safety of both the operator and the person whose body surface is covered.
  • the pulse source of the high voltage is a piezoelectric element
  • the flocator further comprises means for deforming the piezoelectric element.
  • a piezoelectric element can be made in the form of two columns of piezoelectric ceramics with a metal plate between their ends, like a piezoelectric element of a kitchen lighter. The columns are pre-pressed to each other. When squeezing the columns, Due to the direct piezoelectric effect, a high-voltage, pressure-dependent voltage relative to the metal plate between them is created at the outer ends of the columns. With the release of pressure, as well as due to the draining of the charge, the voltage decreases, and, therefore, a voltage pulse is created.
  • the deformation means is made in a very simple way - like a lever brought out of the housing.
  • the task of shaking the flocator can be solved by the manual shaking described above or by using a vibrator integrated in the flocator body, which can be either a mechanical device or an electromechanical device powered by a low-voltage power supply, which, together with its switching means, can also be located inside the flocator case.
  • a vibrator integrated in the flocator body which can be either a mechanical device or an electromechanical device powered by a low-voltage power supply, which, together with its switching means, can also be located inside the flocator case.
  • FIG. 1 schematically shows a device according to the invention for applying a pile coating (flocator);
  • FIG. 2 shows graphs of a surface coating process
  • FIG. 3 shows a photograph of the surface of a false nail with a flock coating.
  • FIG. 1 shows a flocator, which comprises a housing 1 of dielectric material with a container attached to it
  • a source of high voltage in the form of a piezoelectric element, which includes two columns
  • the means of deformation of the piezoelectric element includes a metal base b with a support 7 attached to the wall of the housing 1 and pivotally a lever 8 connected to it, the end of which in the form of a handle extends outward of the housing 1. On the lever 8 and on the support 7 there are clamps 9, 10, which in the inoperative state compress the columns 3, 4 to each other.
  • a vibrator 11 with a power source inside (not shown) and a switch 12 that controls the vibrator power source are located inside the housing.
  • the metal plate 5 is connected by a high-voltage cable directly to the first electrode 13, which is located inside the container 2, and the base 6 is connected by a low-voltage wire to the second electrode 14.
  • a lock 15 is located inside the container 2, and the container 2 is closed by a mesh 16 made of dielectric material.
  • the device operates as follows.
  • the flocator is placed over the area of the human surface covered with an adhesive substance, which must be covered with a flock, for example, a nail coated with an adhesive substance.
  • a second electrode 14 is placed under or near the indicated surface 14.
  • the flock 15 fibers charged by the first electrode 13 start moving out of the outlet of the container 2 through the grid 16 and move in the direction of this zone under the influence of gravitational forces.
  • the pulse duration is determined by the pressure on the lever handle 8 and the charge draining from the piezoelectric element due to the loading of particles, ionization of air, etc.
  • the flock fibers are charged and move along the lines of force of the created electrostatic field. Since the flock fibers are not only charged, but also polarized, when generating a high-voltage pulse, they are located along the field lines of the field, almost perpendicular to the surface being treated. Upon reaching the surface, the fiber fields oriented along the lines of force pierce with one end into the layer of adhesive substance and remain in this condition.
  • Fibers that are not oriented along the field lines of force can also fall onto the layer of adhesive substance, and some of them falling onto the specified layer at an angle under the influence of the next pulse due to their polarization takes a position perpendicular to the surface. With time and the number of voltage pulses, the number of particles having this position increases and reaches a certain value, which characterizes the attractive appearance of the surface covered with a pile. Fibers that do not adhere to the adhesive layer are then removed, for example, by blowing or vacuuming.
  • FIG. Figure 2 shows graphs of the time functions of the relative flow rate of the flock from the container 2 (curve 1), the high-voltage voltage (curve 2) and the relative number of fibers that are glued at one end to the adhesive substance, i.e., they take part in creating the surface appearance (curve, built on the basis of experimental observations 3).
  • the duration of the high voltage voltage pulses is of the order of several seconds, the duration of the coating process is several tens of seconds.
  • Curve 1 corresponds to the situation when the downward flocator is shaken at the moments tl, t4, t7, when the operator, monitoring the flow rate of the flock, considers this necessary.
  • Curve 2 At moments t2, t3, t5, t6, t8, t9, determined by the operator, he initiates the generation of high-voltage voltage pulses (curve 2), which cause the fibers to be oriented along the field lines, both those moving in the direction of the surface and located on the surface and still capable of such orientation. So, during the action of the pulses, the relative number of fibers (curve 3), correctly oriented on the surface, grows and finally reaches the amount sufficient to create the desired surface type, shown in FIG. 3.
  • Curve 4 for the same value as curve 3 is plotted under the assumption of a constant electrostatic field during the same coating time with the same function of the flow rate of the flock (curve 1).
  • a piezoelectric element as a source of high-voltage voltage can significantly simplify the design and cost of the flocator, as well as reduce the mass of the flocator and increase its reliability compared to the known device.
  • a field strength sufficient for flocking due to the electrification phenomenon can be created between the first electrode and the surface closest to it. through the influence and without location under or near the surface of the second electrode to be coated.
  • a hand-held portable flocator was created, which, due to the creation of a pulsed electrostatic field, has increased safety and which, when using a piezoelectric element as a source of high-voltage voltage pulses, is a lighter, simpler and cheaper device for applying flock to a specific area of the surface of the human body.
