At least a portion of the liquid guiding the aerosol matrix is ​​in contact with the first liquid guiding element to adsorb the aerosol matrix in the first liquid guiding element. The heating element is in contact with the liquid guiding the aerosol matrix adsorbed by the liquid guiding the aerosol matrix.

[0028] According to the atomizing core in the above embodiments, by setting the adsorption force of the second liquid guiding element on the aerosol matrix to be greater than that of the first liquid guiding element, when the liquid guiding assembly adsorbs the aerosol matrix, the second liquid guiding element, located at a higher position, can counteract at least part of the gravity of the aerosol matrix within the second liquid guiding element through a stronger adsorption force. This slows down the rate at which the aerosol matrix within the second liquid guiding element flows to the first liquid guiding element, ensuring that the aerosol matrix within both the first and second liquid guiding elements is distributed as evenly as possible.

Simultaneously, by positioning the liquid inlet channel directly opposite the heating element, the flow path of the aerosol matrix can be shortened, allowing the aerosol matrix adsorbed by the liquid guiding assembly to quickly provide heating and atomization to the heating element, thus preventing the liquid guiding assembly from dry-burning during atomization.

[0040] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary composition and / or order.

[0042] This application provides an atomizing device, such as... Figure 1 and Figure 2 As shown, the atomizing device may include a liquid storage component 1, an atomizing core 2, and a power supply component 3. The liquid storage component 1 can be used to store the aerosol matrix and provide heating to the atomizing core 2 to generate aerosol. The power supply component 3 is electrically connected to the atomizing core 2 and is used to supply power to the atomizing core 2. The atomizing device can be a disposable product, that is, the liquid storage component 1, the atomizing core 2, and the power supply component 3 can be packaged in the same housing. Alternatively, the atomizing device can also be a replaceable product, that is, the liquid storage component 1, the atomizing core 2, and the power supply component 3 can be packaged in different housings, and the different housings can be detachably connected by screws, plugs, or magnetic attraction, so that the liquid storage component 1 and / or the atomizing core 2 can be replaced according to the user's needs. This application does not impose any special limitations on the specific structure of the atomizing device.

[0043] In some embodiments, such as Figure 2 and Figure 3 As shown, the liquid storage assembly 1 may include a housing 11, a support 12, a first seal 13, and a second seal 14. The support 12 is installed inside the housing 11, and the first seal 13 is installed between the support 12 and the housing 11, forming a liquid storage cavity 15 between the first seal 13 and the housing 11. The liquid storage cavity 15 is used to store the aerosol matrix. The second seal 14 is installed on the side of the support 12 opposite to the first seal 13, forming a liquid passage cavity 16 between the first seal 13, the support 12, and the second seal 14. The liquid passage cavity 16 is used to receive the aerosol matrix. The first seal 13 is provided with a liquid passage 17, and the liquid storage cavity 15 communicates with the liquid passage cavity 16 through the liquid passage 17, allowing the aerosol matrix stored in the liquid storage cavity 15 to flow into the liquid passage cavity 16 under gravity. In addition, the atomizing device may also include a blocking element 4 and an actuating component 5. The blocking element 4 passes through the liquid passage 16 and the liquid channel 17, so that the blocking element 4 is disposed between the liquid storage chamber 15 and the liquid passage 16. The actuating component 5 is connected to one end of the blocking element 4 and is used to drive the blocking element 4 to move axially along the liquid passage 17. The other end of the blocking element 4 is used to open or close the liquid passage 17.

[0044] The actuation component 5 may include a knob, a gear, and a rack. The knob is rotatably mounted on the housing 11. The gear is connected to the knob. One end of the rack is meshed with the gear, and the other end of the rack is connected to the sealing element 4. When the user rotates the knob, the knob drives the gear to rotate and drives the rack to move up and down, thereby causing the sealing element 4 to open or close the liquid passage 17 axially, thus controlling the flow of the aerosol matrix in the storage chamber 15 into the liquid passage 16. In other embodiments, the actuation component 5 may also be configured as a structure including a toggle and a connecting rod. The toggle is slidably connected to the housing 11, and the two ends of the connecting rod are respectively connected to the toggle and the sealing element 4, allowing the user to toggle the toggle along a straight line on the housing 11. The toggle drives the sealing element 4 to move up and down through the connecting rod, thereby opening or closing the liquid passage 17. This application does not impose any special limitations on the specific structure of the actuation component 5.

[0045] In addition, such as Figure 2 and Figure 3 As shown, the power supply component 3 may include a circuit board 31 and a battery cell 32. The atomizing core 2 passes through the first sealing member 13 and is electrically connected to the circuit board 31. The circuit board 31 is electrically connected to the battery cell 32, so that the battery cell 32 can supply power to the atomizing core 2 through the circuit board 31. To enrich the functionality of the atomizing core 2, the power supply component 3 may also include electronic components such as a controller, a charging interface, and an airflow sensor, all of which are electrically connected to the circuit board 31. The controller can be used to control the heating power of the atomizing core 2, the charging interface can be used to connect an external power source to charge the battery cell 32, and the airflow sensor can be used to sense changes in airflow when the user uses the atomizing core 2. This application does not impose any special limitations on the specific structure of the power supply component 3.

[0046] It is understood that the atomizing device of this application is not limited to having a liquid storage chamber 15 and a liquid passage chamber 16 in the liquid storage component 1. In other embodiments, the liquid storage component 1 can also be configured as an independent liquid storage tank for storing the aerosol matrix, and a portion of the atomizing core 2 can be directly disposed in the liquid storage tank, so that the aerosol matrix in the liquid storage tank can flow into the atomizing core 2 for heating and atomization. The portion of the atomizing core 2 located outside the liquid storage tank can be electrically connected to the power supply component 3, so that the power supply component 3 can supply power to the atomizing core 2. This application does not impose any special restrictions on the specific structure of the liquid storage component 1.

[0047] The above embodiments describe the overall structure of the atomizing device. To address the problem of insufficient localized liquid supply in the liquid guiding component of the atomizing device, this application also provides an atomizing core 2, such as... Figure 4 and Figure 5As shown, the atomizing core 2 may include a liquid guiding assembly 21, a heating assembly 22, and a support assembly 23. The liquid guiding assembly 21 can be used to adsorb aerosol matrix. The liquid guiding assembly 21 may include a first liquid guiding element 211 and a second liquid guiding element 212. The first liquid guiding element 211 is disposed below the second liquid guiding element 212 along the direction of gravity (the downward direction shown by the arrow in the figure), and the second liquid guiding element 212 is in contact with the first liquid guiding element 211. The heating assembly 22 is at least partially in contact with the liquid guiding assembly 21 for heating. The aerosol matrix adsorbed by the liquid guiding component 21 is atomized; the support component 23 has a liquid inlet channel (the part with the flow direction shown by the solid arrow in the figure), the liquid guiding component 21 is installed on the support component 23, and a part of the liquid guiding component 21 is located in the liquid inlet channel; wherein, the adsorption force of the second liquid guiding component 212 on the aerosol matrix is ​​greater than the adsorption force of the first liquid guiding component 211 on the aerosol matrix, so as to counteract at least part of the gravity of the aerosol matrix adsorbed by the second liquid guiding component 212, and the liquid inlet channel is directly opposite the heating component 22.

[0048] This application sets the adsorption force of the second liquid guiding component 212 on the aerosol matrix to be greater than that of the first liquid guiding component 211 on the aerosol matrix. This allows the second liquid guiding component 212, located at a higher position, to counteract at least part of the gravity of the aerosol matrix within it when the liquid guiding assembly 21 adsorbs the aerosol matrix. This slows down the flow rate of the aerosol matrix from the second liquid guiding component 212 to the first liquid guiding component 211, ensuring a more uniform distribution of the aerosol matrix within both components. This reduces the problem of insufficient localized liquid supply caused by the aerosol matrix flowing from the second liquid guiding component 212 to the first liquid guiding component 211 under gravity. Simultaneously, positioning the liquid inlet channel directly opposite the heating element 22 shortens the flow path of the aerosol matrix, allowing the aerosol matrix adsorbed by the liquid guiding assembly 21 to be quickly heated and atomized by the heating element 22, thus preventing the liquid guiding assembly 21 from burning dry during atomization.

[0049] It is understood that the liquid guiding component 21 provided in this application is not limited to use in liquid storage components 1 with a liquid storage chamber 15 and a liquid passage chamber 16, but is also applicable to liquid storage components 1 with independent liquid storage chambers. When the liquid guiding component 21 adsorbs the aerosol matrix, the second liquid guiding element 212, located at a higher position, can counteract at least part of the gravity of the aerosol matrix within the second liquid guiding element 212 through stronger adsorption force, thus keeping the aerosol matrix within the liquid guiding component 21 in a state of vertical equilibrium. However, the flow of the aerosol matrix from the second liquid guiding element 212 into the first liquid guiding element 211 depends not only on the gravity of the aerosol matrix, but also on the adsorption force of the first liquid guiding element 211. For example, when the aerosol matrix in the first liquid guiding element 211 is consumed, the aerosol matrix in the second liquid guiding element 212 can still flow to the first liquid guiding element 211 under the adsorption force of the first liquid guiding element 211, thereby maintaining the aerosol matrix within the liquid guiding component 21 in a state of vertical equilibrium.

[0050] To make the adsorption force of the second liquid guiding element 212 greater than that of the first liquid guiding element 211, such as Figures 6 to 8 As shown, the first liquid guiding element 211 has a plurality of first capillary pores 213, and the second liquid guiding element 212 has a plurality of second capillary pores 214; the density of the second capillary pores 214 can be greater than the density of the first capillary pores 213; and / or, the pore diameter of the second capillary pores 214 can be smaller than the pore diameter of the first capillary pores 213.

[0051] For example, such as Figure 6 As shown, the pore size of the first capillary 213 in the first liquid guiding component 211 can be the same as the pore size of the second capillary 214 in the second liquid guiding component 212. However, the density of the second capillary 214 in the second liquid guiding component 212 is greater than the density of the first capillary 213 in the first liquid guiding component 211. This makes the porosity of the second liquid guiding component 212 greater than that of the first liquid guiding component 211. As a result, the second liquid guiding component 212 can adsorb a larger amount of aerosol matrix more quickly than the first liquid guiding component 211, thereby increasing the adsorption force of the second liquid guiding component 212.

[0052] For example, such as Figure 7 As shown, the density of the first capillary pore 213 in the first liquid guiding element 211 can be the same as the density of the second capillary pore 214 in the second liquid guiding element 212, but the pore diameter of the second capillary pore 214 is smaller than that of the first capillary pore 213. According to the capillary principle, the smaller the pore diameter of the capillary, the greater the adsorption force generated by the capillary under the action of liquid tension, which can draw the liquid into the capillary more quickly and effectively, thus making the adsorption force of the second liquid guiding element 212 greater than that of the first liquid guiding element 211.

[0053] For example, such as Figure 8As shown, the density of the second capillary pores 214 in the second liquid guiding element 212 is greater than the density of the first capillary pores 213 in the first liquid guiding element 211, and the pore diameter of the second capillary pores 214 is smaller than the pore diameter of the first capillary pores 213. In this way, a large number of capillaries have smaller pore diameters, allowing the adsorption forces of the capillaries to be superimposed and work together to increase the total adsorption force of the second liquid guiding element 212, thereby improving the adsorption force of the second liquid guiding element 212.

[0054] In other embodiments, the material of the first liquid guiding component 211 can be non-woven fabric, porous ceramic, fiber, sponge or water-absorbing polymer, and the material of the second liquid guiding component 212 can be non-woven fabric, porous ceramic, fiber, sponge or water-absorbing polymer; wherein, the adsorption force of the material of the second liquid guiding component 212 is greater than the adsorption force of the material of the first liquid guiding component 211.

[0055] For example, the first liquid guiding component 211 can be made of a non-woven fabric material with absorbent properties, and the second liquid guiding component 212 can be made of a water-absorbing polymer material with stronger absorbent properties than the first liquid guiding component 211, thereby making the absorbent properties of the second liquid guiding component 212 greater than those of the first liquid guiding component 211. The materials of the first liquid guiding component 211 and the second liquid guiding component 212 include, but are not limited to, polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), polyurethane (PA), etc. This application does not impose any special restrictions on the specific materials of the first liquid guiding component 211 and the second liquid guiding component 212.

[0056] Furthermore, the materials of the first liquid guiding element 211 and the second liquid guiding element 212 can be combined with the capillary density and / or pore size of the first liquid guiding element 211 and the second liquid guiding element 212 to increase the adsorption force of the second liquid guiding element 212. For example, the first liquid guiding element 211 is made of non-woven fabric, and the second liquid guiding element 212 is made of a water-absorbing polymer material with stronger adsorption force than the first liquid guiding element 211. At the same time, the density of the second capillary pores 214 in the second liquid guiding element 212 is greater than the density of the first capillary pores 213 in the first liquid guiding element 211. As another example, the first liquid guiding element 211 is made of non-woven fabric, and the second liquid guiding element 212 is made of a water-absorbing polymer material with stronger adsorption force than the first liquid guiding element 211. At the same time, the pore size of the second capillary pores 214 in the second liquid guiding element 212 is smaller than the pore size of the first capillary pores 213 in the first liquid guiding element 211. For example, the first liquid guiding component 211 is made of non-woven fabric, and the second liquid guiding component 212 is made of a water-absorbing polymer material with stronger adsorption force than the first liquid guiding component 211. At the same time, the density of the second capillary 214 in the second liquid guiding component 212 is greater than the density of the first capillary 213 in the first liquid guiding component 211, and the pore size of the second capillary 214 is smaller than the pore size of the first capillary 213.

[0057] It should be noted that the number of liquid guiding elements in the liquid guiding assembly 21 is not limited to the first liquid guiding element 211 and the second liquid guiding element 212. For example, the liquid guiding assembly 21 may also include a third liquid guiding element, a fourth liquid guiding element, or more liquid guiding elements, with different liquid guiding elements having different adsorption forces. Along the direction of gravity, liquid guiding elements with greater adsorption forces are placed at higher positions, and liquid guiding elements with less adsorption forces are placed at lower positions. When the liquid guiding assembly 21 adsorbs the aerosol matrix, the aerosol matrix can continuously rise from the liquid guiding element with less adsorption force to the liquid guiding element with greater adsorption force within the liquid guiding assembly 21, so that the aerosol matrix is ​​more evenly distributed within the liquid guiding assembly 21, avoiding the problem of insufficient local liquid supply in the liquid guiding assembly 21. This application does not impose any special limitation on the specific number of liquid guiding elements in the liquid guiding assembly 21.

[0058] The above embodiments provide a detailed description of the specific structure of the liquid guiding component 21 in the atomizing core 2. The following embodiments will provide a detailed description of the specific structure of the internal atomizing component 21 in the atomizing core 2. Figure 4 and Figure 5 As shown, the heating component 22 may include a heating element 221 and a liquid guide 222; the adsorption force of the liquid guide 222 on the aerosol matrix is ​​greater than or equal to the adsorption force of the first liquid guide 211 on the aerosol matrix, at least a portion of the liquid guide 222 is in contact with the first liquid guide 211 to adsorb the aerosol matrix in the first liquid guide 211, and the heating element 221 is in contact with the liquid guide 222 to heat the aerosol matrix adsorbed by the liquid guide 222.

[0059] During atomization, the heating element 22 heats the aerosol matrix adsorbed by the first liquid guide 211, causing it to be continuously consumed. Although the second liquid guide 212 can counteract the gravity of the aerosol matrix within it with stronger adsorption, after the aerosol matrix in the first liquid guide 211 is consumed, the aerosol matrix in the second liquid guide 212 can still flow back to the first liquid guide 211 under its adsorption force to replenish it, thus preventing scorching caused by insufficient liquid supply. When the atomizing core 2 stops atomizing, the first liquid guide 211 can adsorb the aerosol matrix stored in the liquid storage component 1, and the second liquid guide 212 can continuously adsorb and store the aerosol matrix in the first liquid guide 211 with its stronger adsorption force. This process is repeated to ensure that the atomizing core 2 does not experience insufficient liquid supply throughout the entire atomization process.

[0060] In other embodiments, the heating element 22 may also contact the second liquid guide 212 to heat the aerosol matrix adsorbed by the second liquid guide 212. During atomization, the heating element 22 heats the aerosol matrix adsorbed by the second liquid guide 212, causing the aerosol matrix within the second liquid guide 212 to be continuously consumed. Because the second liquid guide 212 has a stronger adsorption force, it can continuously adsorb the aerosol matrix within the first liquid guide 211, thereby replenishing the aerosol matrix within the second liquid guide 212 and preventing scorching due to insufficient liquid supply. When the atomizing core 2 stops atomizing, the second liquid guide 212 can still adsorb and store the aerosol matrix from the first liquid guide 211 using its stronger adsorption force. This cycle ensures that the atomizing core 2 will not experience insufficient liquid supply throughout the atomization process.

[0061] Furthermore, the heating element 22 can contact both the first liquid guide 222 and the second liquid guide 212 to heat the aerosol matrix in both liquid guides 222 and 212. During atomization, the heating element 22 heats the aerosol matrix in the first liquid guide 222 and / or the second liquid guide 212, causing the aerosol matrix in the first liquid guide 222 and / or the second liquid guide 212 to be continuously consumed. Since the aerosol matrix in the first liquid guide 211 and the second liquid guide 212 is uniformly distributed, the aerosol matrix in one liquid guide can be replenished by the aerosol matrix in the other liquid guide after the aerosol matrix in one liquid guide is consumed, thereby avoiding the problem of insufficient liquid supply in the liquid guide 21 during the entire atomization process. Therefore, this application does not impose any special restrictions on the specific location of the heating element 22 on the liquid guide 21.

[0062] Furthermore, the adsorption force of the liquid guide 222 on the aerosol matrix is ​​set to be greater than or equal to the adsorption force of the first liquid guide 211 on the aerosol matrix. This allows the liquid guide 222 to quickly provide the aerosol matrix adsorbed by the first liquid guide 211 to the heating element 221 for heating and atomization, thus avoiding problems such as dry burning of the liquid guide 222 or leakage of the aerosol matrix from the first liquid guide 211 due to poor liquid guiding performance. In addition, by setting the liquid guide 222 between the heating element 221 and the first liquid guide 211, the high temperature of the heating element 221 during operation can also be isolated by the liquid guide 222, thereby reducing the high temperature damage to the first liquid guide 211 during the operation of the heating element 221 and extending the life of the first liquid guide 211 during the use of the atomizing core 2. The heating element 221 can be configured as a metal heating mesh or a metal heating wire structure, and the liquid conductor 222 can be made of materials such as non-woven fabric, porous ceramic, fiber, sponge or water-absorbing polymer. This application does not impose any special restrictions on the specific materials of the heating element 221 and the liquid conductor 222.

[0063] In some embodiments, such as Figure 4 and Figure 5 As shown, the support assembly 23 may include an atomizing frame 231; the liquid inlet channel may include a hollow portion 2310 disposed on the side wall of the atomizing frame 231, the liquid guiding assembly 21 is installed on the outer wall of the atomizing frame 231, the heating assembly 22 is installed on the inner wall of the atomizing frame 231, and at least a portion of the heating assembly 22 is in contact with the first liquid guiding member 211 through the hollow portion 2310.

[0064] For example, the atomizing frame 231 can be configured as a cylindrical structure, with the liquid guiding component 21 sleeved on the outer wall of the atomizing frame 231, the liquid guiding component 222 sleeved on the inner wall of the atomizing frame 231, and the heating element 221 sleeved on the inner wall of the liquid guiding component 222. Thus, the atomizing frame 231 can support the liquid guiding component 21 and the heating element 22, fixing the relative position between the heating element 22 and the first liquid guiding component 211. A perforated portion 2310 is provided at the position of the first liquid guiding component 211, allowing the aerosol matrix to flow from the first liquid guiding component 211 to the liquid guiding component 222, so that the heating element 221 can heat and atomize it to generate an aerosol. Furthermore, the perforated portion 2310 can increase the contact area between the first liquid guiding component 211 and the liquid guiding component 222, making it easier for the aerosol matrix to flow from the first liquid guiding component 211 to the liquid guiding component 222. The atomizer 231 can be made of fiberglass tube. This application does not impose any special restrictions on the specific structure and material of the atomizer 231.

[0065] In addition, such as Figure 4 and Figure 5 As shown, the support assembly 23 may also include an atomizing hood 232; the liquid inlet channel may also include a liquid passage hole 2320 disposed on the side wall of the atomizing hood 232, the liquid passage hole 2320 facing the heating element 22, and a cavity 233 is formed between the atomizing hood 232 and the atomizing frame 231. The first liquid guide 211 and the second liquid guide 212 are disposed in the cavity 233, and the inner surfaces of the first liquid guide 211 and the second liquid guide 212 are in contact with the outer wall of the atomizing frame 231, and the outer surfaces of the first liquid guide 211 and the second liquid guide 212 are in contact with the inner wall of the atomizing hood 232.

[0066] When the liquid passage 2320 is directly opposite the heating element 22, the aerosol matrix flowing into the first liquid guide 211 from the liquid passage 2320 can flow in a straight line towards the heating element 22, thus minimizing the flow path of the aerosol matrix. This avoids the problem of the aerosol matrix not flowing into the liquid guide 222 when the heating element 22 is working due to the liquid passage 2320 being misaligned with the heating element 22. Furthermore, the receiving cavity 233 formed between the atomizing cover 232 and the atomizing frame 231 allows the liquid guide component 21 to be clamped between the atomizing cover 232 and the atomizing frame 231 after being inserted into the receiving cavity 233, thereby ensuring the relatively fixed position of the liquid guide component 21. Figure 3 As shown, the atomizing device may further include a lower seal 24 and an upper seal 25. The axial length of the atomizing cover 232 may be greater than the length of the liquid guiding assembly 21, that is, the top of the atomizing cover 232 may be higher than the top of the second liquid guiding member 212, and the bottom of the atomizing cover 232 may be lower than the bottom of the first liquid guiding member 211. This allows the top of the atomizing cover 232 to accommodate the upper seal 25 to seal the top of the atomizing core 2, and the bottom of the atomizing cover 232 to accommodate the lower seal 24 to seal the bottom of the atomizing core 2. The atomizing cover 232 may be made of plastic, and this application does not impose any special restrictions on the specific structure and material of the atomizing cover 232.

[0067] Among them, such as Figure 4 As shown, the surface of the atomizing frame 231 inside the second liquid guiding member 212 is a closed surface, and the surface of the atomizing cover 232 outside the second liquid guiding member 212 is a closed surface.

[0068] In this way, no holes are provided on the atomizing frame 231 and atomizing cover 232 at the location of the second liquid guiding component 212, so that the second liquid guiding component 212 is in a relatively closed space, which prevents the aerosol matrix inside the second liquid guiding component 212 from leaking from the atomizing frame 231 or atomizing cover 232, thereby improving the anti-leakage performance of the atomizing core 2.

[0069] In addition, such as Figure 4 and Figure 5 As shown, the atomizing hood 232 has a plurality of liquid passage holes 2320, which are disposed on the outer periphery of the first liquid guiding member 211 so that the aerosol matrix can flow from the plurality of liquid passage holes 2320 to the first liquid guiding member 211.

[0070] When the aerosol matrix flows into the liquid passage chamber 16, the aerosol matrix in the liquid passage chamber 16 can flow into the atomizing core 2 for heating and atomization from different directions through the liquid passage holes 2320, thereby avoiding the dry burning problem caused by insufficient local liquid supply to the liquid guiding assembly 21. In addition, the liquid passage holes 2320 can also be set at the bottom of the liquid passage chamber 16, so that all the aerosol matrix in the liquid passage chamber 16 can flow into the atomizing core 2 through the liquid passage holes 2320, thereby improving the utilization rate of the aerosol matrix.

[0071] In this application, the liquid storage chamber 15 can be considered as the first liquid storage mechanism, the liquid passage chamber 16 as the second liquid storage mechanism, and the liquid guiding assembly 21 as the third liquid storage mechanism, thereby enabling the aerosol matrix in the atomizing device to be supplied to the heating element 221 in stages for heating and atomization. When the aerosol matrix in the liquid storage chamber 15 is insufficient, the liquid passage chamber 16 and the liquid guiding assembly 21 can continue to supply liquid to the heating element 221, and when the aerosol matrix in the liquid passage chamber 16 is insufficient, the liquid guiding assembly 21 can continue to supply liquid to the heating element 221. This avoids the problem of dry burning caused by insufficient local liquid supply to the atomizing device in the liquid guiding assembly.

[0072] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
