Liquid derivatives allow liquid to flow in from the top side, so unlike liquids flowing in from the side, oil and liquid do not leak easily.

Description

Technology Field

[0001] The present invention relates to atomization technology, and in particular to an electronic aerosol generating device and an atomizer thereof. Background Technology

[0002] An electronic atomizer is a device that electrically heats a liquid to convert it into vapor when it reaches its boiling point, and it is widely used today in electronic cigarettes and medical / beauty devices.

[0003] An electronic atomizer comprises an atomizer, the core of which is the atomizing core. The atomizing core generally includes a mutually matching liquid derivative and a heating element. Here, a porous ceramic-type hard liquid derivative material is widely used due to its ease of assembly. The liquid derivative typically adopts a block structure with side oil injection, and a heating element is installed on the bottom surface (atomizing surface) to heat the liquid.

[0004] Here, the atomizing liquid gradually penetrates from the liquid induction surface into the atomizing surface, and a heating element in the atomizing surface heats and atomizes the liquid. The aerosol formed by heating and atomization is guided out of the atomizer from the circumferential side of the liquid induction and can be inhaled by the user. Since the path through which the aerosol flows is relatively long, the taste may change due to a drop in temperature during the flow process, or some aerosol may condense, resulting in a lack of uniformity in the atomizing flavor, and inhaling the condensed liquid may harm one's health.

[0005] In addition, when the condensed liquid flows inside the atomizer, it may leak out of the atomizer, and in severe cases, this can damage the circuit components of the electronic atomizer, thereby affecting the lifespan of the electronic atomizer.

[0006] Today, the liquid atomizing of the atomizing core penetrates into the atomizing surface through its liquid induction surface. If the liquid atomizing cannot be heated and atomized by the heating element on the atomizing surface, there is a possibility that the liquid atomizing may leak and drip from the atomizing core. If this liquid atomizing enters the airflow passage, the aerosol is inhaled by the consumer under the action of the airflow due to the consumer's inhalation, and if the liquid atomizing leaks out of the atomizer, it can likewise damage the circuit elements of the electronic atomizing device.

[0007] Finally, vertically positioned liquid derivatives adopt lateral oil injection, which results in poor sealing and assembly, or require the use of more assembly parts for sealing and assembly, leading to problems such as easy oil leakage or high costs. Prior art literature

[0036] In the description below, specific details such as specific system structures and technologies are presented for illustrative rather than limiting purposes to enable a thorough understanding of the embodiments of the present invention. However, a person skilled in the art should clearly understand that the present invention can be realized in other embodiments without such specific details. In other situations, detailed descriptions of already known systems, devices, circuits, and methods should be omitted to prevent unnecessary details from hindering the description of the present invention.

[0037] The electronic aerosol generating device disclosed in the present invention comprises an atomizer and a power supply connected to the atomizer. The electronic aerosol generating device may be applied to electronic cigarettes or medical / cosmetic applications, but is not limited thereto, and forms an aerosol by heating and atomizing a liquid atomizing agent (such as tobacco oil or medicinal liquid).

[0038] Referring to FIGS. 1 to 6, the atomizer of the present invention comprises an outer housing (10) and an atomizing body installed inside the outer housing (10), and the atomizing body comprises a fixed assembly (20) and an atomizing assembly (30) installed in the fixed assembly (20).

[0039] The above-mentioned outer housing (10) is provided with a liquid storage cavity (11) and an air guide tube (12), and the air guide tube (12) is installed to extend in the longitudinal direction, and an air guide passage and a liquid guide passage are installed in the atomizing body, and the air guide passage and the air guide tube (12) are connected and communicating, and the liquid guide passage and the liquid storage cavity (11) are communicating.

[0040] When combining FIGS. 10 to 12 or FIGS. 13 to 15, the atomizing assembly (30) comprises a liquid inducer (31) and a heating element (32), and the liquid inducer (31) is provided with an air induction hole (311) that penetrates longitudinally, and the liquid inducer (31) is further provided with at least one liquid induction groove (312), and the at least one liquid induction groove (312) comprises at least one first sub-liquid induction groove (3121) and at least one second sub-liquid induction groove (3122), the first sub-liquid induction groove (3121) and the second sub-liquid induction groove (3122) are in communication, and the first sub-liquid induction groove (3121) is in communication with a liquid induction passage.

[0041] The wall of the air induction hole (311) opposite to the second sub-liquid induction groove (3122) forms a non-condensing surface (3122a), and a heating element (32) is installed in the non-condensing surface (3122a).

[0042] To be understood, the air induction hole (311) is installed at the center of the liquid induction (31), which is close to the air outlet of the atomizer, and the aerosol generated in the atomizing assembly (30) enters directly into the air induction tube (12) through the air induction hole (311). Since the flow path of the aerosol is relatively short, it is difficult to impair the taste due to a drop in temperature, and the taste is close to the original taste of the liquid atomizer. Furthermore, it is possible to effectively prevent condensation due to a drop in temperature during the flow of the aerosol, and as the aerosol flows, it is possible to prevent the consumer from inhaling the condensed liquid generated and to prevent the condensed liquid from damaging the atomizer or power supply device, thereby improving the service life of the atomizer.

[0043] Additionally, a heating element (32) is installed on the wall of the air induction hole (311) which is mainly opposite the second sub-liquid induction groove (3122). When the heating element (32) mainly heats and atomizes the liquid in the second sub-liquid induction groove (3122), the liquid in the liquid storage cavity (11) passes through the first sub-liquid induction groove (3121) and enters the second sub-liquid induction groove (3122). When the liquid in the second sub-liquid induction groove (3122) is consumed, the liquid in the first sub-liquid induction groove (3121) is replenished into the second sub-liquid induction groove (3122), thereby ensuring a smooth liquid supply and preventing oil leakage.

[0044] Specifically, the liquid inducer (31) is generally a square structure, having a relatively installed upper surface and a lower surface, and the liquid inducer groove (312) is formed by being installed so as to be recessed from the upper surface toward one side of the lower surface, and is a non-penetrating concave groove structure.

[0045] In some embodiments, as shown in FIG. 12, the depth of the first sub-liquid induction groove (3121) is smaller than the depth of the second sub-liquid induction groove (3122), and the cross-sectional width of the first sub-liquid induction groove (3121) is equal to the cross-sectional width of the second sub-liquid induction groove (3122).

[0046] In some embodiments, the depth of the first sub-liquid induction groove (3121) is smaller than the depth of the second sub-liquid induction groove (3122), and the cross-sectional width of the first sub-liquid induction groove (3121) is larger than the cross-sectional width of the second sub-liquid induction groove (3122).

[0047] For better understanding, the dimensions relative to the depth and cross-sectional width of the first sub-liquid induction groove (3121) and the second sub-liquid induction groove (3122) are adjusted as needed, and a heating element (32) is installed mainly on the wall of the air induction hole (311) relative to the second sub-liquid induction groove (3122). By the heating element (32) mainly heating and atomizing the liquid in the second sub-liquid induction groove (3122), the liquid in the liquid storage cavity (11) passes through the first sub-liquid induction groove (3121) and enters the second sub-liquid induction groove (3122). When the liquid in the second sub-liquid induction groove (3122) is consumed, the liquid in the first sub-liquid induction groove (3121) is replenished into the second sub-liquid induction groove (3122), thereby ensuring a smooth liquid supply and preventing oil leakage.

[0048] In some embodiments, as shown in FIG. 10, the liquid induction groove (312) is installed on the outer ring of the air induction hole (311), and the liquid induction groove (312) is usually a C-shaped or U-shaped structure, and the liquid induction groove (312) includes two first sub-liquid induction grooves (3121) and one second sub-liquid induction groove (3122), each end of the second sub-liquid induction groove (3122) is connected and communicated with the two first sub-liquid induction grooves (3121), and atomized liquid flows into the second sub-liquid induction groove (3122) after passing through the two first sub-liquid induction grooves (3121).

[0049] In some embodiments, as shown in FIG. 13, the number of liquid induction grooves (312) is at least two, and at least two liquid induction grooves (312) are spaced apart on the outer circumference of the air induction hole (311). Here, the second sub-liquid induction grooves (3122) of at least two liquid induction grooves (312) are in communication with each other, or the second sub-liquid induction grooves (3122) of at least two liquid induction grooves (312) are not in communication with each other. Preferably, the second sub-liquid induction grooves (3122) of at least two liquid induction grooves (312) are not in communication, and the amount of vaporization can be controlled independently.

[0050] In some embodiments, since the wall surface of the air induction hole (311) opposite the second sub-liquid induction groove (3122) is flat or arched, the atomizer (3122a) may be a flat structure (as shown in FIG. 12) or an arched structure (as shown in FIG. 13).

[0051] In some embodiments, a liquid storage groove (313) is further installed in the bottom portion of the liquid inducer (31). Since the liquid storage groove (313) avoids the liquid inducer groove (312), it is possible to prevent direct communication with the liquid inducer groove (312). The liquid storage groove (313) may have an opening installed downward, and the groove width of the liquid storage groove (313) may be selected from 0.1 to 0.8 mm, for example, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, or 0.8 mm, and the groove depth of the liquid storage groove (313) may be selected from 0.5 mm to 2 mm, for example, 0.5 mm, 1 mm, 1.5 mm, or 2 mm.

[0052] To be able to understand, in some special environments, for example, when the external atmospheric pressure is relatively low, the pressure inside the external housing (10) (or atomizer) is higher than the external atmospheric pressure, that is, when there is a pressure difference between the two, the gas inside the external housing (10) can expand, so that some of the atomized liquid inside the liquid derivative (31) can be extruded out of the liquid derivative (31), and a receiving space is formed in the internal cavity of the liquid storage groove (313) to absorb some of the atomized liquid, and since the groove width of the liquid storage groove (313) is relatively narrow, the atomized liquid remains inside the liquid storage groove (313) through its own capillary tension and does not leak out of the liquid derivative (31), thereby preventing the oil and liquid from leaking out.

[0053] Preferably, the cross-section of the liquid storage groove (313) is arch-shaped. The cross-sectional shape of the liquid storage groove (313) may be C-shaped, U-shaped, straight, L-shaped, etc., and its structure and size are selected and installed according to actual needs, so they are not specifically limited here.

[0054] In some embodiments, the heating element (32) comprises a heating portion (321) and at least two electrode portions (322) connected to the heating portion (321), the heating portion (321) is bonded or inlaid on the atomizer (3122a), and the ends of the at least two electrode portions (322) are bonded or inlaid on the liquid inducer (31). Preferably, the heating element (32) has a planar structure, and the planar structure is relatively flat and difficult to deform, allowing for simpler bonding processing to the liquid inducer (31). Additionally, when the ends of the electrode portions (322) are inlaid on the bottom of the liquid inducer (31), the circuit contact of the electrode portions (322) is prevented from becoming unstable due to factors such as pulling, thereby improving stability when operating the atomizer.

[0055] In some embodiments, it can be understood that the liquid derivative (31) is manufactured by a porous ceramic, and the material of the manufactured liquid derivative (31) may be a porous material having a capillary effect of microholes, such as foamed metal, porous glass, or hard glass fiber tube.

[0056] After electricity is passed through the heating element (32) described above, heating the liquid stored in the second sub-liquid induction groove (3122) can generate an aerosol that the user can inhale directly. The heating element (321) may be a sheet-type heating mesh, and the heating element (321) may be bonded and fixed to the atomizing surface (3122a). The heating element (321) may be a disc-shaped filament formed in a curved shape or a grill-shaped heating piece, and the heating element (321) may be attached to the atomizing surface (3122a) described above by being sintered with the liquid inducer (31) to form an integrated structure. In some embodiments, the heating element (321) described above may be formed in a heating circuit, heating track, heating coating, or heating film, etc., on the atomizing surface (3122a). Since the structural shape thereof may vary, it can be selected as needed. When the second sub-liquid induction groove (3122) is installed in correspondence with the aforementioned heating mesh, filament, heating piece, heating circuit, heating track, heating coating, or heating film, the distance between the second sub-liquid induction groove (3122) and the heating part (321) is minimized, so that a vaporizing liquid such as tobacco oil can be rapidly brought to the heating part (321) and atomized. The aforementioned electrode part (322) may have a sheet-type structure or a cylindrical or rod-type structure.

[0057] Preferably, the material of the heating element (32) may be a metal material having appropriate resistance, a metal alloy, graphite, carbon, a conductive ceramic or other ceramic material, or a composite material of a metal material. A metal or alloy material having appropriate resistance includes at least one of nickel, cobalt, zirconium, titanium, nickel alloy, cobalt alloy, zirconium alloy, titanium alloy, nickel-chromium alloy, nickel-iron alloy, iron-chromium alloy, iron-chromium alloy, iron-chromium-aluminum alloy, titanium alloy, iron-manganese-aluminum-based alloy, and stainless steel.

[0058] Referring to FIGS. 3 and 4, in some embodiments, a liquid storage cavity (11) capable of storing atomizing liquid is installed inside the outer housing (10), an air discharge hole is installed at the top of the outer housing (10), and an air guide pipe (12) extends downward around the perimeter of the air discharge hole.

[0059] Furthermore, the outer housing (10) is manufactured from a hard insulating material, such as phenolic plastics, urethane plastics, epoxy plastics, unsaturated polyester resin, furan resin, silicone resin, allyl resin, etc., and modified resins thereof, which can be used to manufacture the substrate. The outer housing (10) is generally a longitudinal structure extending along a central axis direction, that is, the length along the central axis direction is greater than the width and thickness in the two vertical directions in the cross-section, and an air discharge hole is installed at the top of the outer housing (10), and an air guide pipe (12) extends downward around the perimeter of the air discharge hole. The bottom of the outer housing (10) is open, and a liquid storage cavity (11) capable of storing atomizing liquid is formed inside the outer housing (10). The above air guide tube (12) can be manufactured from a metal member such as stainless steel, and this exhibits a hollow circular tube structure. Of course, the above air guide tube (12) can also be manufactured from a polymer compound with excellent stability, and its material, shape, and size can be selected and installed as needed, so it is not specifically limited.

[0060] Referring to FIGS. 3 through 9, in some embodiments, the fixing assembly (20) includes a mutually matching sealing cover (21) and a bracket (22). The sealing cover (21) and the bracket (22) may be made of an insulating material, for example, silicone or rubber.

[0061] Specifically, referring to FIGS. 5 and 6, the sealing cover (21) is cylindrical in shape and is installed over the upper part of the bracket (22). The sealing cover (21) includes a top wall (211) and a perimeter wall (212) extending from the top wall (211). An air guide (2111) and at least one liquid inlet hole (2112) are installed in the top wall (211); the air guide (2111) is installed extending longitudinally and is connected to and communicates with the air guide pipe (12); and the liquid inlet hole (2112) is connected to the liquid storage cavity (11). The number and location of the liquid inlet holes (2112) correspond to each other in the first sub-liquid guide groove (3121).

[0062] The bracket (22) is cylindrical in shape and the bracket (22) includes a top portion (221) and a side portion (222) extending from the top portion (221), at least one liquid induction hole (2211) is installed in the top portion (221), and a receiving cavity (A) (as shown in FIG. 7 and FIG. 8) is installed in the inner cavity of the side portion (222), and an atomizing assembly (30) is installed inside the receiving cavity (A) (as shown in FIG. 9), and the atomizing assembly (30) is press-fitted and mounted inside the receiving cavity (A).

[0063] The above liquid induction holes (2211) are installed relative to the liquid inflow holes (2112) and the first sub-liquid induction groove (3121), respectively, and are connected, so that the liquid induction holes (2211) and the liquid inflow holes (2112) form a liquid induction passage. The number and installation positions of the above liquid induction holes (2211) correspond to each other in the first sub-liquid induction groove (3121). Preferably, the hole diameters of the liquid inflow holes (2112) and the liquid induction holes (2211) are appropriately adjusted according to actual needs to further adjust the liquid inflow rate and liquid inflow velocity of the atomized liquid.

[0064] Of course, the receiving cavity (A) can also be formed by being installed in a recessed shape on the lower side of the top part (221), and the shape and space size of the receiving cavity (A) are close to the liquid derivative (31).

[0065] In some embodiments, a convex portion (2113) is further installed on one side of the top wall (211) facing the bracket (22); at least one ventilation hole (2212) is further installed in the top portion (221), and an airflow passage (2221) (as shown in FIG. 5) is installed in the side portion (222), and the ventilation hole (2212) and the airflow passage (2221) are in communication, and the airflow passage (2221) is a side wall that penetrates the side portion (222) and extends from the side portion (222) to communicate with the ventilation hole (2212), and one or more airflow passages (2221) may be installed. Of course, the airflow passage (2221) may also be installed in the top portion (221), which penetrates from the side wall of the top portion (221) and extends to the ventilation hole (2212).

[0066] The convex portion (2113) and the ventilation hole (2212) are inserted, connected, and fixed, and a gap (2212a) exists between the outer circumference of the convex portion (2113) and the inner circumference of the ventilation hole (2212). The width of the gap (2212a) is typically 0.1 to 0.8 mm, and may be 0.1 mm, 0.2 mm, 0.3 mm, or 0.4 mm. The gap (2212a) must have a relatively small cross-sectional area so that oil and liquid do not leak (the relatively small cross-sectional area causes the liquid to gather inside the gap (2212a), and through the capillary tension of the liquid inside the gap (2212a), it resists the pressure of the liquid storage cavity (11) to form a valve formed of liquid, and when the air pressure inside the liquid storage cavity (11) is lower than a certain limit value, the external space is inside the ventilation hole (2212). After pushing the liquid toward the inside of the liquid storage cavity (11) and external air is replenished into the liquid storage cavity (11) to reach the pressure balance of the liquid storage cavity (11), the liquid flows into the ventilation hole (2212) and forms a seal through the tension of the liquid itself. Since it is difficult to machine a relatively small hole in the bracket (22), by designing a mutually matched convex portion (2113) and ventilation hole (2212) on the sealing cover (21) and the bracket (22), the cross-sectional size of the convex portion (2113) is somewhat smaller than the cross-sectional size of the ventilation hole (2212), and a relatively small gap (2212a) can be formed through the combination of the two. Additionally, a gap is formed between the top wall (211) and the top portion (221), so that the gap (2212a) can be connected to a part of the liquid inflow hole (2112).

[0067] The above gap (2212a), liquid inlet hole (2112) forms an airflow passage (2221) and a ventilation balance passage (E) (as shown in FIG. 3 and FIG. 8).

[0068] To be able to understand, after the liquid in the liquid storage cavity (11) is consumed, more space is created, and the air pressure in the liquid storage cavity (11) becomes lower than the external air pressure, and external air tends to flow into the liquid storage cavity (11). If air flows in through the micro-holes of the liquid inducer (31), it may occupy the micro-hole passages and affect the liquid supply. Therefore, a ventilation balance passage (E) is required so that external air can flow into the liquid storage cavity (11), so that the liquid induction efficiency of the atomization assembly (30) is not affected, and the ventilation balance passage (E) balances the air pressure in the liquid storage cavity (11), thereby ensuring that the atomization assembly (30) can smoothly supply liquid.

[0069] In some embodiments, a recess (2213) is installed on one side of the top portion (221) facing the sealing cover (21) so that an air guide (2111) can be received therein, and the two are fixed by press fitting. Preferably, the recess (2213) may be in the form of a bearing groove structure (as shown in FIG. 7). The internal cavity of the recess (2213) and the air guide (2111) are matched to form an air guide passage.

[0070] In some embodiments, referring to FIGS. 6 and FIGS. 7, a liquid storage passage (B) is further installed in the side (222), and the liquid storage passage (B) is connected to the receiving cavity (A) and the liquid derivative (31), respectively. The cross-section of the liquid storage passage (B) is generally a T-shaped structure, and the liquid storage passage (B) is installed to prevent the hole on the mold from becoming too thick and deforming when the bracket (22) is injection molded, while serving to store some liquid through the formed groove. When some unusual ventilation, such as high altitude and low pressure, occurs, the air pressure inside the liquid storage cavity (11) rises, and the gas expands, causing some atomizing liquid to be extruded. The excess atomizing liquid reaches the outside of the liquid storage cavity (11) through the liquid inducer (31) or the ventilation hole (2212). At this time, a small portion of atomizing liquid can be stored inside the liquid storage passage (B), so that the atomizing liquid does not fall out of the atomizer and leak. The liquid storage passage (B) extends into the receiving cavity (A) above, and when there is little atomizing liquid in the liquid inducer (31), the atomizing liquid inside the liquid storage passage (B) can be absorbed through capillary action, thereby preventing leakage and waste of the atomizing liquid. It can prevent that.

[0071] In some embodiments, referring to FIGS. 3, 4, 5, and 6, the fixing assembly (20) further comprises a sealing gasket (26), the sealing gasket (26) is installed inside a receiving cavity (A), and the sealing gasket (26) is provided with an air induction through-hole (261) and a liquid induction through-hole (262), and the air induction through-hole (261) and the air induction hole (311) are in communication with each other. Each of the liquid induction through-holes (262) is installed relative to the liquid induction hole (2211) and the second sub-liquid induction groove (3122) and is in communication with them.

[0072] As shown in the combination of FIGS. 3, 4, 5, and 6, in some embodiments, the fixing assembly (20) further includes a base (23), and the bracket (22) and the base (23) are detachably connected. Preferably, a sealing ring (24) is further installed between the outer circumference of the base (23) and the inner circumference of the outer housing (10).

[0073] A conductive member (25) is further installed on the base (23), and the conductive member (25) and the heating element (32) are connected.

[0074] Specifically, the base (23) includes a base wall (231) and a support wall (232) extending from the base wall (231), and the support wall (232) may have a ring-shaped structure, so the base (23) may generally have a cylindrical structure or a half-wrapped structure, and an air inlet (2311) is installed in the bottom wall (231), and the air inlet (2311) is generally cylindrical or cylindrical, and a mounting groove (2312) is further installed in the bottom wall (231), and a conductive member (25) is installed through the mounting groove (2312) and connected to the electrode portion of the heating element (32), and preferably, the conductive member (25) is a conductive column, and the conductive column (25) can support a liquid inducer (31) to a certain level.

[0075] A first buckle groove (2321) is installed in the support wall (232), and a first buckle part (2222) that is mutually coupled with the first buckle groove (2321) is installed in the side part (222) described above, and the two are buckled connected. Additionally, a second buckle part (2322) is further installed on the outer side of the support wall (232), and a second buckle groove (10a) is further installed on the inner wall of the outer housing (10) near the opening, and the second buckle part (2322) and the second buckle groove (10a) are mutually buckled and connected.

[0076] In addition, a ring-shaped sealing groove (232a) is further installed on the outer side of the support wall (232), and the sealing ring (24) described above can be mounted inside the sealing groove (232a) to improve the sealing performance of the atomizer. The sealing ring (24) can be made of rubber or silicone.

[0077] As illustrated in FIGS. 3 and 4, when the atomizer is operated, the atomizing liquid inside the liquid storage cavity (11) enters the first sub-liquid induction groove (3121) through the liquid induction passage, and is then guided from the first sub-liquid induction groove (3121) into the second sub-liquid induction groove (3122). The electrode portion (322) of the heating element (32) supplies electricity and heats and atomizes the atomizing liquid penetrating into the atomizing surface (3122a) through the heating portion (321) to generate an aerosol. Here, as illustrated in FIG. 3, route (C) is an air induction route, and route (D) is a liquid induction route.

[0078] External air is introduced into the air induction hole (311) of the atomizing assembly (30) by the air inlet (2311) of the base (23), and the aerosol is discharged through the air induction passage and the air induction pipe (12) so that consumers can use it.

[0079] To be understood, the air induction hole (311) is installed at the center of the liquid induction (31), which is close to the air outlet of the atomizer, and the aerosol generated in the atomizing assembly (30) enters directly into the air induction tube (12) through the air induction hole (311). Since the flow path of the aerosol is relatively short, it is difficult to impair the taste due to a drop in temperature, and the taste is close to the original taste of the liquid atomizer. Furthermore, it is possible to effectively prevent condensation due to a drop in temperature during the flow of the aerosol, and as the aerosol flows, it is possible to prevent the consumer from inhaling the condensed liquid generated and to prevent the condensed liquid from damaging the atomizer or power supply device, thereby improving the service life of the atomizer.

[0080] The liquid inducer (31) allows liquid to flow in from the upper side, unlike liquid flowing in from the side, so oil and liquid do not leak easily, the atomizing assembly (30) is installed more easily, and fewer sealing members are required.

[0081] The above-described embodiments merely provide a more specific and detailed explanation of preferred embodiments of the present invention, but they should not be understood as limiting the scope of the patent of the present invention. A person skilled in the art may freely combine, modify, and improve the above technical features without departing from the idea of ​​the present invention, and such combinations and modifications shall fall within the scope of protection of the present invention. Accordingly, all equivalent transformations and modifications to the scope of the claims of the present invention shall be included within the scope of the claims of the present invention.
