Definitions

  • the present invention relates to an apparatus for personal care.
  • Apparatuses specially designed for oral hygiene are known for cleaning teeth and massaging the gums by spraying a liquid, in particular CH-A-604678.
  • These devices generally include a tank for the cleaning liquid, a nozzle connected to the tank by a supply pipe and a pump making it possible to pump the liquid from the tank to the nozzle.
  • the nozzle is generally removably mounted on a handpiece in order to allow various users of the same family to use their personal nozzle.
  • the handpiece is designed in such a way that the nozzle projects a jet of pulsed liquid onto the gum or the teeth.
  • Some handpieces are also designed so that the spray nozzle can be replaced by a toothbrush which happens to be driven in an oscillating movement by a hydraulic motor mounted in the handpiece, as described in German patents 1 802 838 and French 2,357,752.
  • These combined devices advantageously make it possible to ensure complete hygiene of the mouth with a minimum of instruments, since on the same handpiece operating with a single device, the various members of the same family can use alternatively their spray nozzle or personal toothbrush.
  • DE-A 1 802838 it has been mentioned in passing that it is also possible to use spray heads and that by using such a head the pulsed supply of liquid under pressure delivers a very effective mist.
  • this remark was made in connection with the production of a cleaning water jet for the dental interstices and for the massage of the gum.
  • nebulizers have been developed equipped with a special nozzle, the geometry of which makes it possible to create a vortex which causes a projection of liquid in the form of a mist and not of droplets.
  • These devices as known for example from US-A 3 910 266 and which work with hydraulic pumps to create the necessary pressure, make it possible to hydrate the skin, and also to tone it or to clean it thoroughly. These devices are therefore specially designed for their particular function.
  • the first type consists of aerosol containers which work with a pressurized agent, in particular liquefied gas, which has an internal pressure high enough to give, with an appropriate nozzle, a mist.
  • This kind of device is problem-free except that the user is limited to the only product which is stored in the container, therefore to a single flavor and a single composition, unless there are several aerosol containers which risks d 'be bulky, and in addition, after several uses, the pressure inside the container tends to decrease and the mist tends to turn into droplets of liquid, which no longer gives the desired effect.
  • this type of device is not very economical since the containers are not refillable and must be simply thrown away as soon as they are empty, which constitutes unnecessary waste.
  • a second type of known nebulizer is particularly designed for cleaning the skin and for this purpose it sends a cloud of water vapor by means of resistance heating, such an apparatus is for example known under the trade name Saunda.
  • This type of device is primarily used in beauty salons to thoroughly cleanse the skin and is very effective in this area.
  • devices of this type have been known for use at home, projecting a fine mist of water onto the face by means of heating.
  • the present invention proposes to overcome these drawbacks.
  • the invention relates to an apparatus for personal care comprising a handpiece connected by a conduit to a source of liquid, a pump connected to the liquid conduit for projecting said liquid in heterogeneous jets at a frequency between 1000 and 4000 pulses. per minute, interchangeable spray nozzles intended to be mounted on the handpiece for the treatment of teeth and gums, and is characterized by the characteristic clause of claim 1.
  • a unique device is thus obtained for the first time which can advantageously be used both for mouth hygiene and for facial care which avoids waste, is economical, takes up little space and makes it possible to adjust the pressure of the liquid to be the nozzle outlet.
  • various products can be added to the water of the reservoir to hydrate, tone, refresh, perfume the epidermis and it would also be possible to heat this water in the case where the '' we would like to obtain a deep cleaning of the skin.
  • the user holds the same handpiece, whether for oral or facial care, by simply changing the nozzle.
  • This handpiece is much more practical than a conventional nebulizer, because it is lighter and more manageable.
  • the nebulizing nozzle is attached to an axis which can be driven in oscillation, by drive means housed in the handpiece, preferably at an amplitude of 10 ° to 20 ° and at a frequency from 30 to 60 Hz.
  • a combined device usable either with a toothbrush or a nozzle provided with a hollow shaft carrying instruments to which a brush or a nozzle is attached, and comprising a hydraulic or electric motor ensuring the drive in oscillating movement of this shaft if the brush is used
  • a nebulizing nozzle it suffices, when using a nebulizing nozzle, to start and adjust certain characteristics of the motor to obtain the desired amplitude which is smaller than for brushing .
  • the device comprises (fig. 1) a base 1 in which is mounted a liquid pump, not shown, intended to send a liquid, for example water, contained in a removable tank 2, to a handpiece 3 connected to the pump by a conduit 4 and on which can be mounted interchangeable spray nozzles 5.
  • the pump is actuated by a motor giving pulses at a frequency between 1000 to 4000 pulses per minute.
  • the pump being driven by an asynchronous electric motor supplied by a 50 or 60 Hz network, its theoretical maximum frequency will be 3000 or 3600 pulses per minute, respectively. It is therefore reasonable in this case to locate the maximum frequency under load at 3000 pulses per minute.
  • the operation of such an apparatus is described in particular in Swiss patent No. 509 078.
  • the device is provided with three spray nozzles 5 intended to project jets of pulsed liquid for oral hygiene, that is to say the washing of teeth and the massage of the gums.
  • the head of these nozzles is designed so that the liquid flows in a heterogeneous jet so as to ensure an effective massage of the gums.
  • Switching on of the device is controlled by a button 7 and a second button 6 adjusts the pressure.
  • the apparatus further comprises another nozzle 8 called a nebulizing nozzle, the head of which differs from that of the nozzles 5 and is specially designed to spray the liquid in the form of a mist.
  • a nebulizing nozzle the head of which differs from that of the nozzles 5 and is specially designed to spray the liquid in the form of a mist.
  • This head is constituted, according to FIGS. 2 to 6, by an external envelope 9 delimiting an internal chamber 10 approximately cylindrical and which opens to the outside by a circular opening 11.
  • a part 12 of this chamber 10 has a slightly larger diameter and delimits an internal shoulder 13 while the circular opening 11 is surrounded by a flange 14 directed inwards.
  • the chamber 10 communicates with the supply conduit 4 coming from the pump via an internal conduit 15 which passes through the rod of the nozzle 8; an internal core 16, integral with the casing 9 protrudes inside this chamber and its function will be explained later.
  • a cylindrical sleeve 17 which bears against the shoulder 13 and which is provided at its end directed towards the outside with a wall 18.
  • the internal face of this wall 18 is provided with three grooves 19 arranged tangentially to the flared part of a conical central orifice 20 formed in the wall 18 and which opens on the external face of said wall, by a small cylindrical orifice 21
  • the profile of the grooves is trapezoidal, as illustrated in FIG. 4.
  • a cylindrical central axis 22 (fig. 5 and 6) which is blocked between the face d end 23 of the core 16 and the side wall 18 of the sleeve 17.
  • This axis 22 is provided on its periphery with axial ribs 24, of approximately semi-cylindrical section, and which extend over most of its length leaving only one free space 25 on the side which applies as against the side wall 18 of the socket 17.
  • the liquid coming from the reservoir 2 is sent by the pump into the conduit 15, it enters the liquid chamber 10, separates into several paths between the ribs 24 of the axis 22, then it reaches the wall 18 of the socket 17 and fills the small annular chamber 26 delimited by the end 25 of the axis and the wall 18, finally it flows with force in the three tangential grooves 19 formed in the wall 18, which cause it to take a swirling movement in the conical orifice 20 from which it exits in the form of mist through the small cylindrical orifice 21.
  • the pressure of the liquid In order for the nebulization effect to be achieved and for water to penetrate the skin, the pressure of the liquid must be between 2.5 and 10 kg / cm 2 (peak value) or an average value between 1.5 and 3 kg / cm 2 .
  • the three tangential grooves 19, the conical orifice 20 as well as the cylindrical outlet orifice 20 are dimensioned and arranged so as to obtain an optimum mist by the Vortrex effect.
  • the water flow of the mist should be between 10 and 100 ml / minute because only a small amount of water gets inside the skin.
  • This invention advantageously makes it possible to use this nozzle 8 to spray different kinds of liquid onto the face or, if appropriate, another part of the body, for example solutions containing refreshing, invigorating, cleansing, flavoring hydrating substances, etc.
  • FIGS. 7 and 8 is illustrated a second embodiment of a nebulizing nozzle 108 comprising, like the nozzle of FIG. 2, an envelope 109 inside which is formed a chamber 110 into which the supply conduit 115 opens.
  • the circular opening of the envelope 109 is closed by a sleeve 117 pressing against an internal shoulder 113 delimited by a part 112 of the chamber 110 having a diameter greater than that of the interior part of the chamber.
  • One end of the socket 117 is closed by a wall 118 which has the same structure as the wall 18 of the socket 17 in FIG. 2.
  • a cylindrical axis 122 of the same structure as the axis 22 is supported on one side against the internal face of the wall 118 and the other against a core 116 of the chamber 110.
  • the sleeve 117 is welded near the shoulder 113 to the envelope 109 by ultrasound.
  • a tube 128 made of elastic material surrounding the core 116 and pressing on one side against the bottom of the chamber 110 and on the other against the cylindrical axis 122 ensures the axial positioning of this the latter in particular so that the external face of said axis 122 is in contact with the internal face of the wall 118 and to prevent the axis 122 from moving under the effect of vibrations.
  • a spring in place of the tube 128.
  • the pressure to be exerted is relatively low and a tube of rubber or any other elastic material is sufficient and allows to have a symmetrical distribution of the pressure on the axis 122.
  • a filter 129 is interposed between the axis 122 and the core 116 and it rests near its periphery on an internal shoulder 130 of the sleeve 117.
  • the purpose of this filter is to prevent impurities block the orifice 121 of the nozzle or the grooves located inside the socket 117.
  • a deflector 127 having the shape of a cup is rigidly fixed on the front part of the socket and is supported against the periphery of the opening of the casing 109 of the nozzle 108.
  • the shape of the deflector 127 makes it possible to avoid a large disper sion of the mist perpendicular to the axis of the orifice 121 which is thus directed towards the face in the form of a cone whose axis is the axis of the orifice 121.
  • the axis of the rod 131 and the head axis of the nozzle 108 are not perpendicular as is usually the case for the spray nozzles 5 and the nebulizing nozzle 8.
  • the angular position of the rod 131 relative to the head of the nozzle facilitates this operation because thus the user can hold the handpiece in a more natural position ensuring that the mist is directed perpendicular to the skin.
  • nebulizing nozzles could also be mounted on a tankless device, which would be connected directly to a water source, for example a tap.
  • a combined device the handpiece of which is designed to receive, as desired, a spray nozzle for the massage of the gums or a toothbrush, such as the device illustrated in FIG. 9.

  • the handpiece 103 is provided with a hydraulic motor whose piston is mechanically connected with a carrying shaft -instruments on which can be attached by its rod, a toothbrush 105a or a spray nozzle 5 or a nebulizing nozzle 108.
  • the brush 105a is used the hydraulic motor is driven and oscillates the shaft with the toothbrush , if a nozzle is used the hydraulic motor does not work and it is the nozzle alone which is supplied by the pump.
  • Hydraulic motors for driving toothbrushes are known, a preferred type of these motors is described in French Patent No. 2,357,752 and US Patent No. 4,146,020.
  • the piston of such a motor drives in motion oscillating the shaft of the handpiece carrying the toothbrush, itself being driven in an oscillating movement under the action of a liquid pulsed by the pump of the device and a return spring.
  • the cylinder of the hydraulic motor is permanently connected to the outlet of the pump and in the case considered (above-mentioned patents) is a section of the water supply duct for the spray nozzle.
  • a system composed of two distributors makes it possible to regulate the circulation of the liquid in three ways, 1 ° circulation in a closed circuit, that is to say to return upstream of the pump or in the container containing the liquid while the pump works and the handpiece is out of service, 2 ° to go out by the nozzle of giclage for the massage of the gums, and 3 ° to actuate the piston without there being a flow of liquid only by the oscillating movement of a column of liquid, under the action of the pump.
  • the piston of the hydraulic motor remains in principle stationary due to the low pressure pulses and the action of the return spring.
  • Handpiece 103 is provided with such a hydraulic motor.
