Description

The The invention relates to an electric brush whose drive is the bristles not moved to their roots, but at their free tips ends.

A electric brush cleans better than a simple one. There are currently many species and manufacturer of electric brushes.

• – der Betrieb ist zu laut,
• – nur die Borsten, die sich in der Peripherie sich befinden, bewegen sie sich einigermassen, wobei die Borsten, die sich in der nähe der Drehachse sich befinden, keinerlei Bewegungen machen,
• – starre Anordnung der Borsten macht sie unzugänglich für schwierige Stellen,
• – die Federkraft, die durch einem Gelenk oder einer elastischen Stelle an dem Griff ist oft unzureichend für den Zahnfleischschutz.

Disadvantages of conventional electric brushes that have a round brush head:

• - the operation is too loud,
• - Only the bristles that are in the periphery, they move to some extent, with the bristles, which are located near the axis of rotation, make any movements,
• - rigid arrangement of the bristles makes them inaccessible to difficult areas,
• - The spring force caused by a joint or an elastic site on the handle is often insufficient for gum protection.

Of the in the claims 1 to 76 indicated invention is based on the problem, an electrical brush to create, which is able to clean almost silently and gently.

This Problem arises with the features listed in the claims 1 to 76 solved.

• – verbesserte Putz-Vorgang,
• – fast lautloser Betrieb,
• – sehr effiziente Anwendung,
• – perfekte Federkraft, die durch Einzel-Borstenfederung erreicht wird.

Advantages of the invention are:

• - improved plastering process,
• - almost silent operation,
• - very efficient application,
• - perfect spring force, which is achieved by single-bristle suspension.

The novel drive consists of one or more electromagnets 1 that the bristles 2 can set in motion directly. The bristles are not as before to the roots 3 moves, but the bristle tips 4 are set in motion.

This brush has at least one electromagnet 1 up in the brush head 5 is installed.

The Intermediate tooth spaces are better achieved by the movement of the individual bristles. The Tips of the bristles are driven, with their roots almost remain immobile. That makes this brush so efficient that it simply impossible to imagine. It produces almost no noise though she makes very active circular or swinging motions. The bristles can be very be built soft, but only by the magnetic field is correct can straighten up.

The movement of the bristles occurs through the magnetic field interaction between the core 6 the bristles, which consists of a ferromagnetic material, and an electromagnet or air coil 7 which is installed at the edge of the bristle head or under the bristles. The electromagnet is with a control 8th coupled, which may be a signal current generator. The generator may consist of an electronic flip-flop, which generates an alternating current or pulse current. The electromagnet thereby becomes its magnetic field very fast to change. The bristles are sometimes stronger, sometimes weaker or not dressed. The cores 6 that in the bristle tips 4 are built, are generated by the alternating magnetic field fine vibrations whose amplitude can be greatly increased by a resonant resonance. It suffices if the generator generates an alternating current signal which has the same oscillation frequency as the mechanical natural oscillation frequency of the bristles. Depending on the material of the bristles such a natural vibration frequency can be calculated, which can then be used. That's what you have to imagine:
A violin is so loud because it has a resonator that amplifies the vibrations of the wires. Although a small vibrational energy is generated, it is greatly increased and made audible by the resonator. Or simply the example of the bridge and soldiers steps, which run evenly on the bridge and bring them to strong vibrations, if their footsteps should match the natural vibrations of the bridge.

The core, which is implanted in each individual bristle, is coated with the usual material from which conventional bristles are made. For example, two electromagnets can be installed in the brush head, one at the front and the other at the back or both at the side. Also, four or more electromagnets, which are changeable controlled, can be used for the movement of the bristles. Each time an electromagnet is activated, the bristles are attracted in the direction. Due to the magnetic attraction and the fact that the bristles are elastic, they will bend a little bit. Depending on where the core is installed in the tooth bristle, it will bend more or less. The magnetic field of the first solenoid is then turned off and the second solenoid activated. In this way, the bristles are attracted in a different direction and bend again. In principle, only one electromagnet is sufficient, which can switch on and off quickly. The interaction and the movement of the bristles are in the 2 and 3 been presented.

Of the Core can be made of a piece of iron (Iron wire), or made of ferrite powder, in the bristles been pressed in a canal. The production of such bristles is usually unproblematic. First, the iron wires are short cut on a plate by a magnetic field directed upwards and then with the plastic mass of the conventional bristles, cast.

Instead of providing the bristles with a core, they can be made with a ring or a shell 9 which is simply plugged in, equip it ( 5 ). The ring (shell) may be an iron piece, stainless steel or other alloy having ferromagnetic properties. The ring can be firmly welded to the bristle during manufacture by a brief heating. The ring or sheath may be installed at the root area, at the tip area or anywhere between the two areas of the bristles.

The ring or shell may also be a permanent magnet which is pivoted back and forth by the magnetic fields of the electromagnets. The magnetic poles of the permanent magnet can be arranged vertically or horizontally. The frequency of the vibrations is controlled by a built-in regulator 10 regulated. It can be hundreds or even thousands of Hz. The electromagnets are very small and they consume very little energy. The generator that supplies it with energy can generate a sine wave. Equally well suited for a Pulstrom. A simple construction would be a flip-flop consisting of at least two transistors. Also thyristors can be used. They can generate very high pulse currents, which can be temporarily stored by a small capacitor and then passed through the thyristor circuit to the coil or to the solenoid.

The Bristles can be built very soft and they would be very much by the pulse magnetic fields moving harmoniously and waving.

During cleaning, in particular, the bristle tips are caused to oscillate. They rub the surfaces very gently and quickly, whereby the leftovers can be removed reliably and lightning fast. The vibration frequency can be controlled individually by the controller. The brush is very quiet because it has no electric motor or gearbox. It also does not rotate anything in the brush. The bristles simply swing through the invisible magnetic fields, which build up and break down very quickly. The electromagnets or the air coils can also under the bristle-foundation wall 11 be installed or integrated in this wall. The manufacturing process envisages an induction process of the coils, which are then molded into the brush protected with plastic.

This toothed bristle oscillation generating system has many advantages over the conventional brushes, wherein the vibrations are generated by the electric motor coupled to an elongated shaft. The electric motor and the shaft produce unpleasant noises that are difficult to control. The new system can generate much higher vibration frequencies, which can never be achieved with an electric motor. Higher frequencies mean gentle, faster brushing. The noise, that produced by the new brush is merely the vibration of the bristles that vibrate in the air.

A suspension system used in the 7 has been shown, the brush can make very comfortable. The bristle pressure force is damped and regulated by magnetic fields. The system works much like a speaker-membrane-motion system and consists of a solenoid coil 12 attached to a permanent magnet 13 swings. Also, two permanent magnets, which are arranged field-repellent against each other, one is installed under the bristle foundation and the other in the rear toothed bristle head wall, can be used as a spring system. The magnetic fields of the same pole are known to repel each other and this force is not negligible. It increases quadratically with linear distance decrease.

Another brush variant, which also works by electromagnet drive, is in the 8th been presented. This is a brush in which the wall on which the bristles are planted, is flexible. This wall can therefore be bent as desired. A built-in electromagnet 1 under the wall 11 in the brush head 5 is installed, as well as a ferromagnet element 14 , which is built into the wall, can deform this wall. The ferromagnet element can be installed in the middle of the wall as a small sphere, cuboid or a small thin sheet metal layer. Instead of the Ferromagnet element, a very small permanent magnet can be installed. The ferromagnetic element or the permanent magnet is set in oscillatory motion by the magnetic field of the coil or the electromagnet. The wall on which the bristles are installed will be deformed and sometimes convex, sometimes concave. The bristle tips accordingly move towards or away from each other. These vibrations can be generated at a low or very high frequency. A controller can be installed for it. In the variant with the ferromagnet element, a spring 15 be installed, which pushes the center of the wall to the outside and thus produces a convex shape. The electromagnet then can tighten the center and deform it concave. Once the magnetic field is turned off by the controller, the spring pushes the center of the wall outward again and deforms it convexly. The bristle tips move harmoniously together when the wall deforms concavely. They cross each other and thus remove each other's leftovers, which should eventually adhere to the bristle tips. Depending on how the brush is built, the wall on which the bristles are installed can be made oblong, round, square or oval. For an elongated shape (or oval shape), the permanent magnet or the ferromagnetic element could be elongated like a pin 16 along the middle line 17 be installed in the wall. The solenoid or an air coil could also have this shape. Except by an electromagnet, you can of course also with the help of an electric motor 18 create the deformation of the wall. In the 9 such a variant has been presented. Here is the conventional wave 19 with an eccentric part 20 at the end or a slice 21 with valleys 22 and hills 23 the wall of the bristles deformed.

The 10 shows a brush whose bristles are built at least at the roots spiral. The spiral 24 gives the bristles spring properties and makes them very flexible. These bristles can also be installed in a non-electric brush, whereby they would not hurt the gums, because they can yield softly during printing. The advantage lies in the spring force of individual bristles, which can react independently of each other. In a conventional brush, which is equipped with a flexible handle or a spring joint, the spring force can only be done simultaneously for all bristles. This is very inefficient because when pressing harder on the gums, the pressure does not produce all the bristles at the same time, but only a smaller group of them, or even just individuals that are unfavorably located in an inappropriate place. The variant with the spiral spring is able to feather almost every single bristle or bristle group perfectly and independently of the others.

The 11 shows a variant wherein the bristles individually or in groups with a small air-core envelope 25 are shrouded. This shell is capable of generating magnetic fields that move the bristles. The bristles can be made very soft and equipped with tensile fibers. They can only take their straight shape by the magnetic fields when switching on the brush and ready for cleaning.

The 12 shows a variant where a UV LED 26 is installed as a detector for dirt residues. The UV light is probably able to make the layers invisible to normal light visible. This effect is used here to assess the level of cleanliness individually.

In the 13 is a variant with piezo elements 27 been presented. These elements are able to change their thickness under tension and create vibrations.

In the 14 is a variant with magneto-striction elements 28 been presented. These elements can shorten or change their length if they turn into a selonoid coil 29 to find oneself.

The 15 shows a brush whose bristles are in small platelets 30 are distributed, which are separated from each other. These tiles can move or pivot independently of each other. You can use permanent magnet pens 31 equipped by a centrally mounted electromagnet 32 can be attracted or repelled radially, depending on the magnetic field polarity of the electromagnet. In this way, the bristles are moved radially. In particular, the bristle tips are strongly pivoted. The solenoid is coupled to a controller which outputs a pulse current or alternating current.

The 16 is a development of the variant of the 15 , Here are the tiles 30 built in a circular sector. They are at the periphery by an elastic or articulated connection 33 with the edge 34 coupled while floating freely in the middle. They each have a ferromagnetic part or permanent magnet in the center. An elastic insulating wall on which the platelets can be supported may be advantageous for hygienic reasons. This wall would prevent the liquid from entering the empty chamber 35 where the electromagnet is located penetrates.

In the 17 a variant has been shown that with a small plate 36 equipped, which is built circular. The plate is installed parallel to the bristle holder. It has many small holes 37 on, where the bristles have been inserted individually or in groups. This plate or disc has ferromagnetic properties or it consists of a permanent magnet. The plate can be built double, so that a part is displaceable. When the bristles have been inserted in the holes, you can move the plates and thus reduce the holes. In this way, it is firmly attached to the bristles and anchored to a certain height. It interacts with the electromagnet built into the brush to vibrate it. In this way, the bristles are moved. The plate vibrates parallel to the bristle holder and thereby bends the bristles back and forth. The bristle tips are thereby moved gently and very well back and forth. The movement of the tips allows for a better cleaning. The tips can be moved by swinging. The amplitude of the vibrations of the bristle tips is much larger than in conventional brushes.

A battery 38 or a mains connection can put this drive into operation. If you use a power supply, then the power supply should only lower the voltage and not convert the AC to DC or stabilize. The alternating current in the low voltage range can generate the oscillations by the electromagnet without oscillator circuits or generator. Therefore, the production of the brush can be very cheap, because just a few elements must be installed. Also, a power supply by a non-contact power transmission and transformation device, which consists of an insulated coil, which is installed stationary and which is connectable to the socket and a second coil, which is installed in the brush, can be used as a power supply, but is in not quite practical in this case.

A Variant has an audio signal connection point through which the brush can be coupled to the signal output of a music amplifier. In this case, the music signal energy is used as drive energy for the Used swinging elements. The bristles swing with the music frequency. The music determines the purge intensity. The bass tones increase the Amplitude, with the high notes increase the frequency. A volume control regulates the intensity the vibrations.

The brush Can be designed as any cleaning brush be, e.g. as toothbrush, dish brush, shoe brush, car wash brush, floor brush, toilet brush etc.
