Definitions

  • a first component of the appliance has a first section an annular wall of which surrounds a chamber within which a heating element is located.
  • a second component includes a cupped face mask which is to be placed against the face of the user and a second section communicating with the interior of the mask via suitable passages, and having an annular fluid-storage absorbent element of porous material. The sections are telescoped together and can be axially separated, for facilitating access to the fluid-storage element and heating means.
  • the present invention relates generally to an electrically operated appliance and more particularly to an appliance of the type having a facial mask which is to be placed against the face of a user and which produces vapors which are supplied to the interior of the mask.
  • Appliances of this type are already known. They are basically intended for two purposes, either as so called facial-saunas in which the intention is to supply vapors into contact with the facial skin of the user, or for treating the respiratory passages of the user with warm vapors, such as warm air.
  • the appliances comprise a facial mask which is connected via suitable passage means with a component having a chamber in which there is located an annular storage element of porous material which is capable of absorbing water and/or fluids, for instance medication, although separate means for containing the medication (if any is to be provided) can be present.
  • a heating arrangement is provided which provides heat and means is provided for circulating a stream of air over the heating arrangement to be heated thereby and in contact with the porous element to be enriched with water vapor and the like.
  • the purpose is, of course, to supply a stream of moist warm air to the respiratory passages of a user.
  • Another object of the invention is to provide such an improved apparatus in which the storage element is not only readily accessible, but can readily be removed for repair, replacement or the like.
  • one feature of the invention resides in an apparatus of the character outlined herein, which, briefly stated, comprises a first component including a first section provided with wall means surrounding the chamber and heating means located in the chamber.
  • a second component is also provided including a cupped face mask adapted to be placed against the face of a user, and a second section communicating via passage means with the interior of the mask and having an annular fluid-storing element of porous material.
  • the sections are telescoped together so that the fluid-storage element is concentric with the heating means but the sections are nevertheless separable so as to expose the fluid-storage element and the heating means when so separated.
  • the apparatus according to the present invention has the advantage that the fluid-storage element of porous material can readily be not only inspected but also removed for repair or replacement. In fact, it can be readily removed for the purpose of filling it, that is to placed it into a body of liquid which it is to absorb rather than having to place the liquid into the device itself.
  • a separate intermediate member which connects the mask and the wall means and is provided on its side facing the wall means with the advantageously hollowcylindrically configurated storage element.
  • the storage element may be connected with the intermediate member in releasable manner, for instance via a bayonet coupling so that it can be readily separated and reconnected, or a new storage element can be connected with the intermediate member when desired.
  • the intermediate member or a projecting portion thereof can be provided with one or more recesses which cooperate with corresponding projections on the storage element which advantageously is of lime sandstone.
  • the storage element may be provided with a ring, advantageously composed of synthetic plastic material, which carries the projections cooperating with the recesses of the intermediate member.
  • a ring advantageously composed of synthetic plastic material, which carries the projections cooperating with the recesses of the intermediate member.
  • the storage element consist of lime sandstone, but it should consist of a suitably porous material, that is of a material which has the same porousity and absorbtion characteristics as lime sandstone.
  • the intermediate member can be releasably connected with the wall means, again via a suitable bayonet coupling.
  • the wall means advantageously is provided inthe region of that end which faces the intermediate member when the sections are connected, with at least one recess which is preferably located at its inwardly directed side, and which is associated with one or more noses provided on the intermediate member. This means that when a relative rotary displacement between the intermediate member and wall means takes place, the two may be separated or, again be reconnected.
  • the recess or recesses may be provided as circumferentially extending recesses or grooves and to permit entry of the noses into them they may communicate with additional recesses or grooves which extend to the adjacent axial end of the wall means.
  • the circumferentially extending grooves may have a greater depth in radial direction of the wall means than the additional recesses which latter are advantageously of approximately triangular configuration with one corner of the triangle merging with the respectively associated groove and having a dimension permitting one of the noses to pass through it into the groove.
  • the section provided with the wall means and the heating means is further provided with an inner wall which is arranged with inwardly with spacing of the outer wall means and is of tubular configuration, being turnable relative to the outer wall means about itslongitudinal axis.
  • the tubular inner wall may be provided on its side facing the intermediate member with outwardly projecting projections which may be carried on suitable webs which extend into the grooves, so that the extent to which the inner wall means can turn with reference to the outer wall means is limited by the length of the grooves.
  • radial projection of the projections is advantageously greater then the depth of the additional grooves which connect the circumferentially extending grooves at the axial end of the outer'wall means, so that it is not readily possible to withdraw these projections from the respectively associated grooves.
  • various components are made of synthetic plastic material, particularly of thermoplastic material, there is as a rule, a certain resilient deformability characteristic inherent in the material which, makes it possible to assemble and disassemble these components with one another even if in undeformed condition they are so interengaged that they cannot be readily separated.
  • the intermediate member is advantageously provided with edge recesses or cutouts into which the aforementioned projections or webs extend, that is which straddle the projections or webs. These cutouts may merge with or be part of those recesses which cooperate with the projections of the storage element.
  • the circumferentially extending groove sections may be provided with a nose or the like which is elastically deformable and under the influence of a force acting in the circumferential direction of the wall means.
  • a nose or the like which is elastically deformable and under the influence of a force acting in the circumferential direction of the wall means.
  • the nose which acts as a blocking element is not so strong that it would be capable of preventing a turning of the inner wall means when a sufficient torque is exerted.
  • appropriate material for instance, a suitable thermoplastic material, permits the elastic or resilient deformability in the manner outlined earlier.
  • the tubular inner wall means may be provided with an insert carrying the heating means, and the latter may be associated atits region adjacent the intermediate member with annular sealing element of elastomeric material, advantageously silicon rubber.
  • annular sealing element of elastomeric material, advantageously silicon rubber.
  • Such a sealing element would be in sealing relationship with the heating element and the intermediate member and the latter is advantageously provided with an annular step which engages the sealing element. It has also been found advantageous to provide the construction according to the present invention in such a manner that the sealing element, if necessary with the interposition of a spacing ring, is also in engagement with the storage element. When the sealing element is thus under pretension, it acts not only to provide a sealing effect but also to maintain the components which it contacts under a certain amount of stress.
  • the sealing element is thus capable of providing a certain compensation for tolerance variations between the various components so that the latter cannot in normal use move from their respective positions.
  • a suitable-connector is provided for connecting the device with a source of electrical energy.
  • This is advantageously in form of a female connector recessed in the outer side of the outer wall means and accommodating the connector pins, so that a male connector can be inserted into it. It is possible to provide an arrangement in which an electrical connection cannot be carried out or maintained when the device is opened, that is when the sections thereof are separated. This will be discussed in more detail later.
  • a receptacle to be associated with the apparatus according to the invention and having an annular inner space which is accommodated in configuration to the shape of the storage element.
  • the annular inner space may have in its lower portion a less radial dimension than in its upper portion, and the space may be filled with a liquid to be absorbed by the annular storage element which is thereupon inserted into the space.
  • the lower narrower portion of the annular space is made to conform relatively closely to the exterior dimension of the storage element and serves to displace the liquid into the interior of the storage element when the latter is inserted into the space. This is particularly advantageous if theliquid is a mixture of water and medication because the forcible displacement into the interior of the storage element upon insertion of the latter into the annular space, also provides for an enforced admixing of the water and medication.

  • FIGS. 1 13 is composed, insofar as the major elements are concerned, of a mask 20 which is to be placed against the face of a user, an intermediate member 21 which surrounds a chamber, and a section 23 provided with a heating element 22, with the section 23 also serving as a handle.
  • the heating element 22 is connectable with a source of electrical energy (not shown) via a cable or wire 24.
  • the connection between the cable 24 and the heating element 22 is effected as a releasable connection by means of the contacts 25 and the plug 26.
  • Heating element 22 is of tubular configuration and accommodates in its interior a thermostat 27 which is of any type well known to those skilled in the art.
  • the element 22 is surrounded exteriorly by a porous storage element, for instance of lime sandstone or the like, which is identified with reference numeral 28, and is also of tubular configuration.
  • the storage element 28 absorbs liquid. It is in turn surrounded by an inner tubular wall 31 which defines with an outer wall 32 and the storage element 28 respective annular chambers 33 and 34.
  • Apertures 35 are provided in the lower region of the section 23 to permit entry of air first into the chamber 34 and from there through apertures 36 provided in the wall 31 and into the annular chamber 33. The air then flows downwardly in the latter and passes the openings 37 and 38, provided in an insert 39 into the interior space 40 surrounded by heating element 22. From there the air passes having been heated by contact with the heating element 22 via the intermediate member 21 into the mask 20 and into engagement with the facial skin of the user, or if it is being breathed into the respiratory passages of the person whose face is placed against the mask 20.
  • the air is heated to a temperature as desired and which can be selected via the thermostat 27, during its passage through the chambers 33, 34 and the space 40. It also serves to insulate the outer wall 32 and thus to prevent undesired or excessive heating of the same. Furthermore, as the air passes in the aforementioned path, it absorbs moisture from the moisture ladden storage element 28.
  • the storage element 28 should be readily releasable. It is therefore releasably connected with the portion 45 of the intermediate member 21, and the intermediate member 21 and the portion 45 may either be of one-piece with one another or may be separate elements. From the point of view of ease of manufacture, it is preferable that the portion 45 be a separate element and then be later connected with the intermediate member 21, for instance by being adhesively or otherwise bounded thereto.
  • the portion 45 is provided at its free end with recesses 47 which extend from its edge 46 and initially extend in direction parallel with the longitudinal axis of the section 23, whereupon they have a portion 48 which extends approximately in circumferential direction.
  • the arrangement is such that the section 49 of each recess 47 which faces the edge 46, constitutes a complete hole through the wall of the portion 45, whereas the remainder of each recess 47, including the portion 48, is only a groove in the inner wall surface 60.
  • An annular member 51 for instance of synthetic plastic material or the like, is provided at that end of the storage element 28 which is closer to the mask 20.
  • the member 51 is connected with the storage element 28 in suitable manner, for instance by being bounded thereto.
  • the outer periphery of the member 51 is provided with radial projections 52, in the illustrated embodiment two of them which cooperate in the manner of a bayonet coupling with the recesses 47, 48.
  • the portions 48 may be axially inclined of the portion 45, or at least one of their boundary surfaces 27 may be so inclined, to provide for a certain amount of force acting upon the projections 52 and fixing them against undesired displacement.
  • the position of a sealing ring of elastomeric material, advantageously of silicon rubber, further facilitates such fixing.
  • the sealing ring 53 presses via an intermediate ring 54 against the ring 51 and the heating element 22, subjecting it to a certain amount of pretension aside from serving as its desired sealing function.
  • the portion 45 is provided with an annular projection 30 which contacts the median region of the ring 53.
  • Recesses 55 are provided on the inner side of the outer wall 32 in the upper endregion (as seen in FIG. 1) thereof, being located opposite one another and each being composed of two portions 56 and 57.
  • the portion 56 is the upper portion and delimited at one side by two inclined surfaces 58 in such a manner that it is of approximately triangular configuration with one corner of the triangle communicating via a cutout 59 with the portion 57.
  • the portion 57 which is the lower portion, is configurated as a circumferentially extending groove and has a greater radial depth than the respectively upper portion 56, as indicated in FIGS. 6 and 8.
  • the portion 45 of the intermediate member 21 is provided with two radial noses 60 as well as with two outer projections 61 provided at the upper end of the inner wall 31.
  • the projections 61 are each carried by a web 62 which extends upwardly beyond the upper end 23 of the inner wall 21.
  • the upper portion 56 of the respective recesses 55 serves primarily for insertion of the respectively associated nose 60 or projection 61 into the respective lower portion 57.
  • the inner wall 31 is initially inserted into the space surrounded by the outer wall 32, causing the projections 61 first to enter into the respective portions 56 and from there via the cutout 59 into the portion 57.
  • the inclined surfaces 58 guide the projections 51 necessarily in the direction toward the cutout 59.
  • the inner wall 31 is then turned to a position in which the projections 61 assume the location illustrated in FIG. 5, and in which the projections 61 and thus the inner wall 31 are retained by a small stud or projection 64 provided in the region of the portions 57.
  • This stud is advantageously of synthetic plastic material, such as a thermoplastic, and has a certain ability to elastically yield. On the one hand it serves to prevent undesired turning of the inner wall 31 from its position, and on the other hand it is sufficiently yieldable to become elastically deformable under the influence of a torque exerted in circumferential direction to permit the turning of the inner wall 31 if and when this is specifically desired.
  • the portion 45 of the intermediate member 21 can be inserted from above into the upper part of the space surrounded by the outer wall 32.
  • the arrangement of recesses 49 and the portions 47 on the one hand and of the noses 60 on the other hand, with reference to one another is such, as shown in FIG. 5, that when the noses 60 are inserted through the respective cutout 59 into the'lower portion 57 of the recess 55, the recess 49 straddles from above at the lower free end of the portion 45 the respectively associated web 62 of the inner wall 31. This means that in circumferential direction there exists a mechanical connection between the webs 62 on the one hand and the recesses 49 on the other hand.
  • FIG. 7 the components have been illustrated in their connected condition, and here, as in FIGS. 5, 6 and 8, the storage element 28 has been omitted for the sake of clarity of illustration.
  • the arrow 65 in FIG. 7 indicates relative rotational movement of the portion 45 about the longitudinal axis of the section 23, which is to be imparted in order to retain the portion 45 and thereby the intermediate member 21 and the components associated therewith, in the position in which the portion 45 is located within the upper part of the space surrounded by the outer wall 32.
  • FIG. 8 the extent to which such rotational movement is to be effected is designated with reference numeral 36 and it will be appreciated that when the end of the rotational movement indicated by the arrow 65 has been reached, the noses 60 assume the position 60a which is illustrated in'broken'lines in FIGS. 7 and 8.
  • the inner wall 31 has been turned through a corresponding extent, because it is connected with the portion 45 via the webs 62 and the recesses 49, respectively.
  • the projection 64 is elastically deformed in the manner already discussed, to such an extent that it does not permit the rotational movement of the associated web 62.
  • the second position of the projection 61 is not illustrated in FIG. 8 because it was thought advisable to omit this for the sake of clarity of illustration.
  • the inner wall 31 as well as the insert 39 be of a resiliently yieldable synthetic plastic material, advantageously a thermoplastic material.
  • a resiliently yieldable synthetic plastic material advantageously a thermoplastic material.
  • the components have sufficient ability to resiliently yield due to the use of a thermoplastic material.
  • the heating element 22 is carried by the insert 39, with a sealing ring 68 being interposed and with the heating element 22 being retained by clamping members 69 which engage with one end in the openings 37.
  • a mounting member or unit 70 is providedfor the electrical contacts 25, portions of which which are to be inserted into the plug extend into a cutout 71 in the bottom wall 72 which is connected with the outer wall 32. Because of the'previously described connection between the inner wall 31 and the insert 39, the latter has the mounting member 70 participate in the earlierdescribed turning movement.
  • the cutout 71 is so configurated in its outline that its cross section is substantially completely filled when the plug 26 is inserted into it and mates with the contacts 25. 7
  • the various components, in particular the inner wall 31 and the outer wall 32 will in normal use assume the relative position illustrated in FIGS. 1, 2, 4 and 10.
  • the element 28 is to be removed from the section 23 for which purpose the intermediate member 21 with its portion 45 is turned by the distance 66 (see FIGS. 1 and 3) in the direction of the arrow 73 with the reference to the outer wall 32.
  • the outer wall 32 may be composed of two parts 32a and 32b, but this is not necessary.
  • the components have the position illustrated in FIGS. 5 8, and the inner wall 31 has participated in the turning movement due to the connection via the webs 62 and the recesses 49. Similarly, the contacts 25 have also participated in this movement because the mounting member 70 for them turns with the insert 49.
  • the contacts 25 assume at this time an inclined position so that it is impossible to insert the connector 26 and establish a connection with a source of electrical energy, when the device is opened, or when the storage element has been removed. Conversely, it is, of course, impossible to effect relative turning movement of the sections 31 and 32 in a sense opening the apparatus, while the male connector 26 is still located in the cutout 71 and in electrically conductive connection with the contacts 25.
  • an interlocking arrangement which prevents the danger of electrical shock.
  • abutment may be provided'for limiting the relative rotational movement of the components for instance in the region 57 of the recess 55.
  • Projection 76 of the mounting element 70 may also be provided and located so as to contact an associated abutment 77, or the electrical contacts may be so positioned that they abut a sidewall of the cutout 71 and thus limit the relative rotational displacement.
  • FIG. 11 illustrates the storage element 28 which is connected with the portion 45 of the intermediate member 21, showing the storage element 28 as it appears after it has been upwardly withdrawn out of the section 23, or conversely after the section 23 has been downwardly withdrawn.
  • the storage element 28, which may still be connected with the member 21 and possible also with the mask 20, is now sufficiently exposed so that it can be inserted into a separate receptacle 76 having an annular space 77 whose dimensions are accommodated to those of the storage element 28.
  • the lower region of the annular space 77 is designated with reference numeral 78 and advantageously so narrowed that its radial dimension corresponds approximately to the wall thickness of the storage element 28.
  • the storage element 28 can be removed from the portion 45 as shown in FIG. 13 by effecting a relative turning movement of the storage element 28 and the portion 45 in the direction of the arrow 79, thereby separating the storage element 28 .with its associated annular member 51. This makes it possible to very simply and readily remove one storage element 28 and replace it with another. 7
  • the apparatus is reassembled in the manner discussed with reference to FIGS. 8 whereupon the relative rotational displacement in the direction of the arrow 65 (see FIG. 7) is carried out in order to re-connect the elements 21 and 25 on the one hand, and 23 and 32 on the other hand, via the bayonet coupling described earlier.
  • the present invention thus achieves the objects which have been set forth above, and avoids the disadvantages of the prior art.
