Description

"ORAL HYGIENE APPARATUS".
TECHNICAL FIELD OF THE INVENTION
The present invention concerns an oral hygiene apparatus .
In particular the present invention concerns an oral hygiene apparatus for personal use that, through a jet of air or air and liquid of adjustable intensity at the user's discretion, makes it possible, to improve the health of a mouth, fighting the proliferation of bacteria, removing organic particles of food and plaque from the interdental spaces, from the gum line, from beneath dental braces, prostheses, dental implants, bridges, and the like, and from all difficult-to-reach recesses, in a more effective manner than known apparatuses.
STATE OF THE ART
Oral hygiene apparatuses for personal use are known, generally comprising a tank for a liquid associated with a dispensing head for the controlled expulsion of the liquid itself; such a liquid can be. simply water, or even a solution of water and mouthwash, or any other medical liquids..
The user, through the quoted head, can' spray the liquid directing it between the interdental spaces, onto the gum line, or beneath dental braces, prostheses, and. the like, so as to further remove food and plaque residue that the use of just toothbrushes would not be able to eliminate.
However, in known devices the liquids dispensed, being incompressible, upon impact with an obstacle near to a gap tend to rebound almost totally on the surface of the obstacle itself, having greater difficulty in penetrating Between the interdental spaces or into small recesses, such as the gaps beneath dental implants, braces, bridges, .and the like.
In fact, the liquid (water, mouthwash, medical liquids, and the like) of the jet directed under pressure towards a gap smaller than the diameter of the jet itself will tend to rebound on the edges, and also the small amount of liquid that manages to penetrate will have lost part of the starting energy. This prevents effective removal of residual food and plaque, which can cause inflammation and cavities., amongst other things .
Therefore, it is clear, that known oral hygiene apparatuses do not allow effective removal of food or plaque residue from the interdental spaces, from beneath dental implants, braces, bridges, and the like, and from all small recesses.
PURPOSES OF THE INVENTION The technical task of the present invention is therefore to devise an oral hygiene apparatus that makes it possible to effectively remove residual organic particles of food and plaque from the interdental spaces, from the gum line, from beneath dental braces, prostheses, dental implants, bridges, and the like, and from all difficult-to-reach recesses even of small size, fighting the proliferation of ■ , bacteria and eliminating inflammation and cavity- causing agents, so as to improve the health of the mouth with respect to what can be obtained with known apparatuses.
In such a technical task, a particular purpose of the present invention is to make an oral hygiene apparatus that is simple to use and has fast use/maintenance.
This task and this purpose are accomplished by the, oral hygiene apparatus according to the attached claim 1. The oral hygiene apparatus comprises at least one support structure, which is portable and/or able to be fixed to outer surfaces, for at least one compressor slaved at least to a control processor and associated with at least one tank for a liquid, for selectively sending air and. liquid to at least one dispensing head ' associated with the compressor and the' tank; .'the quoted head is suitable for selectively dispensing a jet of air or a jet of air and liquid, at the user's discretion, at a predetermined pressure, for the removal of residual food and plaque from the interdental spaces, from the gum line, from beneath dental braces, prostheses, dental implants, bridges, and the like, for optimal oral hygiene.
Further advantageous characteristics are described in the dependent claims.
BRIE'F DESCRIPTION OF THE DRAWINGS.

- figure 2 is a side view of the oral hygiene apparatus, according to the present invention;
- figure 3 is a detailed schematic ' view of the inside of a dispensing head of the oral hygiene apparatus, according to the present invention.
EMBODIMENTS OF THE INVENTION.
With reference to the attached figure 1, an oral hygiene apparatus, according to the present, invention, is wholly indicated with 1.
The oral hygiene apparatus comprises at least one support structure 2, which is portable and/or able to be fixed to outer surfaces, for at least one compressor 3 slaved at least to a control processor 4 and associated with at least one tank 5 for a liquid, for selectively sending air and liquid to at least one dispensing head 6 associated with the compressor 3 and the tank 5; the quoted head 6 is suitable for selectively dispensing a jet of air or a jet of air and liquid, at the user' s discretion, at a predetermined pressure, for the effective removal .of residual food and plaque from the interdental spaces, from the gum line, from beneath dental braces, prostheses, dental implants, bridges, and the like, for optimal oral hygiene.
In particular, the air, since it is compressible, adapts to the shape of possible obstacles that it encounters, diffusing better into the interdental spaces, under prostheses and in all difficult-to-reach recesses, with sufficient energy to remove the aforementioned residual food and plaque.
The oral hygiene apparatus 1 comprises a switch 7 slaved to the control processor 4 for switching the compressor 3 on and off, and it also comprises a potentiomete -8 , also slaved to the control processor 4, for adjusting the power of the compressor 3 itself. The control processor 4 is for example an electronic logic and power board.
In particular, the quoted dispensing head 6 is associated with the compressor 3 through a first duct 9 for directly sending air from the compressor 3 itself, and it is associated with the tank 5 through a second duct 10 for sending the liquid.
In greater detail, the first duct 9 and the second duct 10 . are flexible, so as to allow- the suitable manoeuvrability of the dispensing head 6 by the user.
The dispensing head 6 comprises a first end nozzle 11 associated with the first duct 9 for the controlled dispensing of the jet of compressed air through the actuation of the switch 7 by the user; the head 6 also comprises a second nozzle 12 associated with the second duct 10 for dispensing the liquid through respective pumping means 13, able to be actuated at the user's discretion, for -selectively dispensing a jet of air, or a jet of air and liquid. The switch 7 is conveniently located on the head 6 itself.
In particular, the first nozzle 11 and the second nozzle 12 are arranged on the dispensing head 6 with the respective axes which are concurrent, so. as to allow the nebulisation of the liquid after it has been mixed with the jet of compressed air itself dispensed by the first nozzle 11.
The dispensing head 6, at the first nozzle 11 and the second nozzle 12, can also comprise an orientable end portion 6a, to direct the jet of air or the jet of air and liquid into the areas to be treated at the user' s discretion.
The dispensing head 6 defines a grip portion 6b for the user.
The quoted pumping means 13 can for example comprise a pump of the diaphragm type able to be actuated manually by the user to draw the liquid from the tank 5.
Such a diaphragm pump is housed in the dispensing head 6 and is associated with the second duct through two respective unidirectional valves 14.
The diaphragm pump comprises at least one elastically deformable portion able to be reached manually by the user through a shaped slot 15 foreseen on the grip portion.6b of the . dispensing head 6 itself.
In greater detail, the diaphragm pump substantially consists of a chamber made from elastically deformable material equipped with an inlet and an outlet associated through the quoted unidirectional valves 14 with two ends of the first duct 9 on which it is arranged.
The tank 5 comprises an opening for the insertion of the liquid and a respective closing cap 16, for example of the screw type.
The oral hygiene apparatus 1 also comprises a filter 17 for purifying the ambient air drawn in by the compressor 3.
The oral hygiene apparatus 1 also comprises a manometer 18 associated with the compressor 3, for the user to directly read the operating pressure.
In particular, the manometer 18 (for example of the analogue type) is associated with a third duct 19, and the first duct 9 and the third duct 19 are associated with the compressor 3 through a fitting element 20.
The apparatus comprises a power supply group 21, for example suitable for connecting to the electrical mains, and/or of the type comprising a rechargeable battery.
The operation of the oral hygiene apparatus 1, according to the invention, according to what has been described, is totally intuitive.
As stated, the oral hygiene' apparatus is of the type easily carried and/or fixed to outer surfaces, so as to be able to be moved easily in the home, or even in professional contexts.
Initially, the tank 5 is empty and the user can decide whether to use the oral hygiene apparatus 1 exclusively with air or also with liquid.
In the case in which the user wishes to use the apparatus 1 also with liquid, it will be sufficient to fill the tank 5 with the desired amount of liquid; for this purpose, the cap 16 is simply unscrewed, the liquid is poured for example through a' suitable container with a spout, and the cap 16 itself is closed again.
The liquid - inserted in the tank 5 can be simply water, or even a solution of water and mouthwash, healing substances, homeopathic remedies, or any other medical liquids.
Once the apparatus 1 is connected to. the electrical mains (or the charged battery is inserted) , the user can then begin to use it, actuating the switch 7 to switch on the compressor 3.
The compressor 3 is of the oil-free type, suitable for medical applications, and for example it can be an oscillating piston compressor, or other types of compressors suitable for the purpose.
The air drawn in by the compressor 3 is purified through the quoted filter 17.
The raising of the pressure can be seen immediately by the user by reading the manometer 18.
It is possible to obtain the desired operating pressure by acting on the potentiometer 8 associated with the control processor 4; in particular, the operating pressures suitable for correct oral cleaning are preferably comprised between 2 bar and 4 bar. This does not mean that the compressor 3 cannot obtain different operating pressure values, even higher ones, according to widely-varying needs.
Thanks to the compressor 3 actuated by the( user through the switch 7, from the first nozzle 11 of the head 6 the jet of air is dispensed at the desired pressure.
At this point the user, if he wishes to mix the liquid with the jet of air, acts manually on the diaphragm pump (made from elastically deformable material) pressing it so as to draw the liquid itself by depression from the tank 5 along the second duct 10, until the liquid is dispensed from the second nozzle 12.
As stated, the axes of the first nozzle 11 and of the second nozzle 12 are concurrent: in this way, the liquid dispensed, mixing with the jet of compressed air dispensed by the first nozzle 11, is nebulised.
The diaphragm pump allows the dispensing and consequently the intermittent nebulisation of the liquid; this does not mean that in other embodiments of the apparatus 1 pumping means 13 of another type cannot be foreseen that also allow the dispensing and the consequent continuous nebulisation of the liquid.
The oral hygiene apparatus 1 can also be used just with air: in this case, in light of the above, its operation is totally intuitive.
r
As described, the user therefore chooses, even alternating with each other, the jet of air or of . air and liquid, directing it thanks to the dispensing head 6 between the interdental spaces, onto the gum line, or beneath dental braces, prostheses, dental implants, bridges, and the like, so as to effectively remove residual food and plaque even from the smallest recesses, for optimal oral hygiene.
Once the correct oral cleaning thanks to the apparatus 1 is complete, the user . switches the compressor 3 off by acting on the switch 7.
As seen, the oral hygiene apparatus 1 allows the selective dispensing of a jet of air, or even of a jet of air and liquid (simply water or even a solution of water and mouthwash, healing substances, homeopathic remedies, or any other medical . liquids) , , at a predetermined pressure at the user' s discretion, for effective oral hygiene.
In particular, the air, being compressible, manages to adapt to the shape of an obstacle (the profile of the teeth at the sides of the dental gaps, parts of braces, prostheses, implants, and the like) and thus penetrate even into the smallest recesses with the energy necessary to remove possible residual food and plaque. In an alternative embodiment, the grip portion 6b of the . dispensing head. 6 can be made from elastically deformable soft material - for example silicone, rubber and the like - so as to allow the actuation of the pumping means 13 without having to foresee the quoted slot 15.
The invention, thus conceived, allows big technical advantages to be obtained.
A big technical advantage consists of the fact that the oral hygiene apparatus 1 allows residual organic food and plaque particles to be effectively removed from the interdental spaces, from the gum line, from beneath dental braces, prostheses, dental implants, bridges, and the like, and from all difficult-to-reach recesses even of small size, fighting the proliferation of bacteria and eliminating inflammation . and cavity- causing agents, so as ' to improve the health of the mouth with respect to what can be obtained with known apparatuses.
The oral hygiene apparatus 1 can also have a double use, professional and in the home: through the delivery of medicinal and/or homeopathic substances, there is indeed the possibility of performing out-patient therapies under dentist's prescription, having the possibility of carrying out the prescribed therapy at home .
It has thus been seen how the invention achieves, the proposed purposes:
The present invention has . been described according to preferred embodiments, but equivalent variants can be conceived without departing from the scope of protection offered by the following claims.
