DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS
[0063] The invention is herein described, by way of example only, with reference to the accompanying drawings. With specific reference now to the drawings in detail, it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of the preferred embodiments of the present invention only, and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the invention. In this regard, no attempt is made to show structural details of the invention in more detail than is necessary for a fundamental understanding of the invention, the description taken with the drawings making apparent to those skilled in the art how the several forms of the invention may be embodied in practice. Throughout the drawings, like-referenced characters are generally used to designate like elements.
[0064] Note: Throughout this disclosure, subscripted reference numbers (e.g., 10.sub.1 or 10.sub.A) may be used to designate multiple separate appearances of elements of a single species, whether in a drawing or not; for example: 10.sub.1 is a single appearance (out of a plurality of appearances) of element 10. The same elements can alternatively be referred to without subscript (e.g., 10 and not 10.sub.1) when not referring to a specific one of the multiple separate appearances, i.e., to the species in general. In some cases, subscripted reference numbers are used to designate an element of the same species having a different design but the same functionality as other elements of the same species.
[0065] For convenience, in the context of the description herein, various terms are presented here. To the extent that definitions are provided, explicitly or implicitly, here or elsewhere in this application, such definitions are understood to be consistent with the usage of the defined terms by those of skill in the pertinent art(s). Furthermore, such definitions are to be construed in the broadest possible sense consistent with such usage.
[0066] A bottle system according to embodiments comprises a bottle and a cap. The cap contains arrangements for use in a mist-delivery device, such as a piezo assembly comprising an ultrasonic mesh membrane, an electrical connection for powering the piezo assembly, and a one-way valve for introducing a liquid such as water or other aqueous liquid into the bottle system. The nebulizer arrangements of the cap are preferably configured to use vibrating mesh technology, as is known in the field of nebulizers, to expel, from the bottle assembly, an aerosol comprising fine droplets of whatever liquid is introduced into the bottle assembly. Fine droplets can be less than 50 microns in diameter, or less than 30 microns in diameter, or less than 20 microns in diameter or less than 10 microns in diameter or even finer. A mesh can be formed, for example, by using a laser to make uniform holes in a metal disk, or by any other known method.
[0067] A mist-delivery system according to embodiments comprises a bottle system as described herein, a housing such as a case or sleeve or housing, a fan, a power supply including (for example) a battery, and control circuitry for controlling the activation and operation of the device. The device is preferably configured to deliver, using the onboard piezo assembly, a mist of droplets comprising an aqueous liquid and, optionally, a biologically-active material in an admixture with the liquid. The mist departing the device can be entrained by an airflow generated by the fan so as to direct the mist in a desired direction and constrain its lateral dispersion.
[0068] Referring now to the figures and in particular to
[0069] A cap 70 for sealing the bottle 50 is illustrated in
[0070] In embodiments, as illustrated in
[0071] An assembled bottle system 100 using the bottle 50 of
[0072]
[0073] In preferred embodiments of the present invention the capillary pathway 90 is installed in the bottle system by the securing of a cap 70 to the aperture 55 of a bottle 50. A capillary pathway 90 as the term is used herein is a material suitable for transport of water (or other aqueous liquid) along a pathway by capillary action. Such a material often includes fibers, such as plant-based fibers e.g., cellulose, polymer-based fibers e.g., polyester, glass fibers e.g., in a woven fabric or bundled or unbundled glass fibers, or carbon fibers. In some non-limiting examples, the fibers can be very small, i.e., having diameters in the range of several or tens of microns. In other examples, the fibers can be larger. While the term pathway may appear to imply that a pathway for water transport to a leak-alarm target may be a direct path, that is not necessarily the case. The transport of water through the capillary pathway may include progression in random directions or omnidirectional progression. In some embodiments, the capillary pathway 90 can include fibers arranged so as to form direct pathways from various parts of the liquid-storage volume 57 but this is not necessary for the capillary transport to be effective. The key in deploying the capillary pathway 90 is to ensure a substantially continuous pathway for the capillary transport regardless of either the direct nature of the transport or the fact that the water may be spread in all directions throughout the capillary pathway material before reaching the target of the transport, i.e., the mesh membrane 85. In some embodiments, the capillary pathway can comprise a hydrophilic material that is effective to facilitate transport of water.
[0074]
[0075]
[0076] As stated hereinabove, a capillary pathway 90 is provided so as to create a transport path for a liquid from the liquid-storage volume 57 of the bottle system 100 to the mesh membrane 85 onboard the cap 70.
[0077] In embodiments, a device for delivering a mist includes a housing. A housing is preferably configured to have a bottle system 100 disposed therewithin, along with a fan for generating an airflow and a power source for activating the piezo assembly 85. The housing also preferably houses control circuitry for controlling the operation of the piezo assembly and the fan.
[0078] Reference is now made to
[0079]
[0080] As can be seen in the schematically drawn perspective cutaway view of
[0081]
[0082] According to embodiments, a user input device or element (not illustrated) such as, without limitation, a button, a slider, a switch or a touchscreen, can be used to activate both the fan 175 and the piezo assembly 80. The user input device or element can be disposed on an external surface of the housing 150, or elsewhere. Activation can be by completing an electrical circuit via electrical connection 159 which is provided for delivering electricity from the power supply 152 to the piezo assembly 80 and optionally to the fan 175. In some embodiments the fan 175 may be connected to the power supply 152 via a different connection (not shown). Upon activation, the fan 175 generates an airflow and the ultrasonic mesh membrane 85 delivers a mist 141 from a liquid stored in the liquid-storage volume 57 of the bottle system 100.
[0083] As the mist 141 begins to disperse upwards and outwards from the mesh membrane 85, the annular airflow entrains a portion of the mist 141. The entrainment has two effects: (i) since the airflow segment AIR3 is directable by directing, e.g., pivoting, the housing 150, the mist 141 is likewise directable in part or entirely together with the airflow segment AIR3, and (ii) lateral dispersion of the mist 141 is constrained by the airflow, meaning that less of the mist disperses laterallyoutside of the surrounding airflow (e.g., the cylindrical airflow of
[0084] Reference is now made to
[0085] In embodiments, a mist-delivery device 200 includes a bottle system 100 and a housing 150 having a plenum 154 in which the bottle system 100 is disposed. In an assembled state, the bottle system 100 is securely, and optionally reversibly, held in a place designated for that purpose. The mist-delivery device 200 also includes control circuitry (not visible; as discussed hereinabove, said control circuitry can be disposed within a closed bottom section 158 of the housing 150 or anywhere else within the housing 150), and a base 190 for supporting the housing 150. The housing 150 preferably comprises a power supply 152, a powered fan 175, an air inlet 155 at a first end of the plenum 154, and an annular air grille 160 as an air outlet at a second end of the plenum 154; the inlet 155 and the outlet 160 defining an airflow path circumventing the replaceable bottle system 100. Note: as used in this disclosure and in the claims appended thereto, the terms air inlet and air outlet should be taken to mean any respective collection of one or more holes, slits, openings, grilles and the like; for example, an air inlet can include a first plurality of openings in a housing and an air outlet can include a second plurality of openings in the same housing, the two pluralities respectively displaced from each other as necessary to define an airflow path.
[0086] As shown in
[0087]
[0088] We now refer to

[0091] Step S01, providing a bottle system 100 comprising bottle 50 having a liquid-storage volume 57, a cap 70 comprising a piezo assembly 80 including an ultrasonic mesh membrane 85, and a capillary pathway 90 for conveying a liquid by capillary action from the liquid-storage volume 57 to the mesh membrane 85 in accordance with any of the embodiments disclosed herein.
[0092] Step S02, introducing an aqueous liquid into the bottle 50 of the bottle system 100 through the unidirectional fluid conveyance (one-way valve) 74. In some embodiments, a quantity of a biologically active substance 96 in a solid phase, is disposedprior to the introduction of the aqueous liquidwithin the internal liquid-storage volume 57 of the provided bottle system 100. In such embodiments, the delivered mist 141 comprises droplets of an admixture of the biologically active substance 96 and the aqueous liquid.
[0093] Step S03, inserting the bottle system 100 into the plenum 154 of a housing 150 of a mist-delivery device 200. The housing 150 comprises a power supply 152, a powered fan 175, an air inlet 155 at a first end of the plenum 154, and an annular air outlet 160 at a second end of the plenum 154, the inlet 155 and outlet 160 defining an airflow path circumventing the inserted bottle system 100.
[0094] Step S04, operating the mist-delivery device 200 to deliver electricity from the power supply 152 to the fan 175 and to the piezo assembly 80, thereby causing the mesh membrane 85 to non-thermally deliver a mist 141 and causing the fan 175 to generate an airflow, fan-generated airflow exiting the annular air outlet 160 surrounds the mist 141, and is effective to entrain a portion of the delivered mist 141 and thereby constrain lateral dispersion of the mist 141.
[0095] In some embodiments, the method can include a fifth step, as illustrated by the flowchart in
[0096] Step S05, pivoting the mist-delivery device 200 to direct the airflow together with the entrained mist 141, e.g., as illustrated schematically in
[0097] In some embodiments, not all of the steps recited in any of the methods are performed.
Additional Discussion
[0098] According to embodiments, a non-thermal mist-delivery device comprises (a) a replaceable bottle system comprising (i) a bottle comprising an internal liquid-storage volume for holding a liquid, (ii) a cap comprising a piezo assembly including an ultrasonically vibrable mesh membrane, and (iii) a capillary pathway for conveying a portion of the liquid by capillary action from the liquid-storage volume to the mesh membrane; (b) a housing shaped to hold the replaceable bottle system therewithin, the housing comprising a fan, an air inlet and an annular air outlet, the inlet and the outlet defining an airflow path circumventing the replaceable bottle; and (c) control circuitry operative to electrically activate the fan and the piezo assembly in response to a user input, respectively to generate an airflow and to non-thermally deliver, via the aerosol outlet, a mist comprising droplets of the liquid, wherein the fan-generated airflow exiting the annular air outlet is effective to entrain a portion of the mist and thereby constrain lateral dispersion of the mist. The bottle system can additionally comprise a bottle-system-electrical-contact connected to the piezo assembly and disposed on an exposed surface of the bottle system. The bottle system can additionally comprise a base for supporting the housing. In some such embodiments, the base can comprise a pivot about which the housing can be caused to pivot through a pivot-range of at least 60. The housing can additionally comprise an aerosol outlet. In some such embodiments, when the bottle system is stably held within the housing, the mesh membrane can face the aerosol outlet. The housing can additionally comprise a housing-electrical-contact. In some such embodiments, when the bottle system is stably held within the housing, the bottle-electric-contact can be in contact with the housing-electric-contact. The defined airflow path can pass through the fan. The mist-delivery device can additionally comprise a power supply for powering the fan and the piezo assembly. The bottle can additionally comprise a neck aperture for introducing a liquid therethrough into the liquid-storage volume at ambient pressure. The cap can comprise a fluid conveyance for introducing a liquid into the liquid-storage volume, the conveyance being configured to preclude egress of the liquid from the bottle.
[0099] In some embodiments, when the cap is secured to the bottle, a central axis of the bottle can pass through the mesh membrane. The cap can be configured to be secured to the bottle to form a liquid tight seal such that liquid can only leave the bottle via the bottle neck through the mesh. The capillary pathway can be attached to the cap such that its assembly in and/or disassembly from the bottle system is together with the cap. The bottle-electrical-contact can be disposed on an exposed surface of the cap. The portion of the mist entrained by the generated airflow can be directable by pivoting the mist-delivery device. The cap can be configured to be reversibly secured to the bottle. The securing of the cap to the bottle can create a waterproof seal between the cap and the neck aperture of the bottle. The disposition of the capillary pathway within the liquid-storage volume can be such that the mist-delivery device is effective, when the piezo assembly is electrically activated and the liquid-storage volume is at least 30% full, to deliver the mist throughout a pivot-range of at least 60, or at least 70. In some embodiments, when the bottle system is in an assembled state and the cap is secured to the bottle, a central axis of the bottle can pass through the mesh membrane. The housing can be caused to pivot through a pivot-range of at least 70. The bottle can have a solid-phase biologically-active material disposed therewithin, which when dissolved or suspended in an aqueous liquid introduced into the liquid-storage volume through the fluid conveyance, is included in droplets of the delivered mist.
