Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to a liquid supply device and an atomizing device. Background Technology

[0002] Electronic atomizing devices are used to atomize aerosol matrix to generate aerosols for users. To meet users' demands for aerosol matrix volume, existing technologies typically use an external reservoir bottle to replenish the aerosol matrix within the electronic atomizing device. However, once the external reservoir bottle is installed, the reservoir on the electronic atomizing device is directly connected to the external reservoir bottle. This prevents users from controlling the flow rate of aerosol matrix from the external reservoir bottle into the reservoir, negatively impacting the user experience. Utility Model Content

[0003] This application provides a liquid supply device and an atomizing device, which aims to solve the technical problem that existing electronic atomizing devices cannot control the flow rate when replenishing the aerosol matrix.

[0004] Some embodiments of this application provide a liquid supply device, including a first liquid storage tank, a second liquid storage tank, and a switch.

The switch is disposed between the walls of the first and second liquid storage tanks and is configured to have a first position and a second position for controlling the connection or disconnection of the first and second liquid storage tanks. When the switch is in the first position, the outlet hole is connected to the inlet hole, and the aerosol matrix in the second liquid storage tank is configured to flow to the first liquid storage tank under gravity. Alternatively, when the switch is in the second position, the outlet hole and the inlet hole are blocked.

[0005] In some embodiments, the switching element includes a separator, the sidewall of which has a liquid passage hole extending through the separator; when the separator is in the first position, at least a portion of the liquid passage hole connects the liquid inlet hole and the liquid outlet hole; or, when the separator is in the second position, the sidewall of the separator is configured to block the liquid inlet hole and / or the liquid outlet hole.

[0007] In some embodiments, the liquid supply device further includes a first seal and a second seal; the first seal is disposed between the liquid inlet and the side wall of the separator, and the second seal is disposed between the liquid outlet and the other side wall of the separator.

[0008] In some embodiments, the liquid supply device further includes a first support, a connector, and a connecting groove; the first support is connected to the first liquid storage tank, one of the connector and the connecting groove is disposed on the first support, and the other of the connector and the connecting groove is disposed on the second liquid storage tank; wherein the relative positions of the second liquid storage tank and the first support are defined by the connector and the connecting groove.

[0009] In some embodiments, the liquid supply device further includes a guide and a guide groove; one of the guide and the guide groove is disposed on the first liquid storage tank or the second liquid storage tank, and the other of the guide and the guide groove is disposed on the switch; wherein, when the switch moves between the first position and the second position, the guide groove is configured to restrict the movement path of the guide.

[0010] In some embodiments, the liquid supply device further includes an electromagnetic drive and a second support. The electromagnetic drive includes a base, a magnetic element, and a coil. The second support is connected to the first or second liquid storage tank. The base is fixed relative to the second support. The magnetic element is movably disposed within the base. The coil is installed within the base and wound around the periphery of the magnetic element.

[0014] According to the liquid supply device in the above embodiments, by setting a first liquid storage chamber and a second liquid storage chamber within the atomizing device, the second liquid storage chamber can be used to replenish the aerosol matrix to the first liquid storage chamber, thus eliminating the need for an external liquid storage bottle to be installed on the atomizing device for replenishment. During replenishment, the user only needs to control the switch to the first or second position to control the flow rate of the aerosol matrix into the first liquid storage chamber, making operation simple and convenient. Simultaneously, by setting the liquid supply device in a structure where the first and second liquid storage chambers are separate, air from the first liquid storage chamber can flow into the second liquid storage chamber when the second liquid storage chamber replenishes the aerosol matrix, thereby reducing the pressure difference within the second liquid storage chamber and preventing leakage of the aerosol matrix due to excessive internal and external pressure differences. Furthermore, placing the switch between the first and second liquid storage chambers avoids the switch occupying the capacity space of either the first or second liquid storage chamber, thus improving the aerosol matrix storage capacity of the liquid supply device.

[0027] 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 components and / or order.

[0028] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0029] This application provides an atomizing device, such as... Figures 1 to 3As shown, the atomizing device may include a housing 1, a liquid supply device 2, an atomizing core assembly 3, and a power supply assembly 4. The liquid supply device 2 can be used to store the aerosol matrix. The atomizing core assembly 3 is disposed within the liquid supply device 2 and is used to heat the aerosol matrix and atomize it to form an aerosol. The power supply assembly 4 is electrically connected to the atomizing core assembly 3 and is used to provide power to the atomizing core assembly 3. The atomizing device can be a disposable product, that is, the atomizing core assembly 3 and the power supply assembly 4 are fixedly connected. Alternatively, the atomizing device can also be a replaceable product, that is, the atomizing core assembly 3 and the liquid supply device 2 can be combined to form an atomizer, and the atomizer is detachably connected to the power supply assembly 4, so that the atomizer can be replaced according to the user's needs. This application does not impose any special restrictions on the specific structural form of the atomizing device.

[0030] In some embodiments, such as Figures 1 to 3 As shown, the outer shell 1 may include an upper shell 11 and a bottom cover 12. The upper shell 11 has a suction nozzle, and the bottom cover 12 can be detachably connected to the upper shell 11 by means of snap-fit, screw-fit, or magnetic attraction. The liquid supply device 2 is installed inside the outer shell 1. The atomizing core assembly 3 may include structures such as an atomizing cover, a liquid guiding component, and a heating element. The heating element may be configured as a heating mesh or heating wire sleeved inside the liquid guiding component. The liquid guiding component is installed inside the atomizing cover with liquid guiding holes, allowing the aerosol matrix to flow into the liquid guiding component through the liquid guiding holes. The power supply assembly 4 may include a circuit board 41 and a battery cell 42. The circuit board 41 is electrically connected to the battery cell 42 and the heating element, respectively, so that the battery cell 42 can supply power to the heating element through the circuit board 41. After the temperature of the heating element rises, it heats the aerosol matrix adsorbed by the liquid guiding component to atomize and generate aerosol. The aerosol can be discharged from the suction nozzle for user use. This application does not impose special limitations on the specific structure of the outer shell 1, the atomizing core assembly 3, and the power supply assembly 4.

[0031] To address the issue of uncontrollable flow rate when replenishing aerosol matrix in electronic atomization devices, this application also provides a liquid supply device 2, such as... Figures 2 to 7As shown, the liquid supply device 2 may include a first liquid storage tank 21, a second liquid storage tank 22, and a switch 23. The first liquid storage tank 21 is used to store the aerosol matrix and has an inlet port 211. The second liquid storage tank 22 is spaced apart from the first liquid storage tank 21 and has an outlet port 221 opposite to the inlet port 211. The second liquid storage tank 22 is used to replenish the aerosol matrix to the first liquid storage tank 21. The switch 23 is disposed on the tank wall of the first liquid storage tank 21 and the first liquid storage tank 22. Between the walls of the two liquid storage tanks 22, a switch 23 is configured to have a first position and a second position for controlling the connection or disconnection of the first liquid storage tank 21 and the second liquid storage tank 22; wherein, when the switch 23 is in the first position, the liquid outlet 221 is connected to the liquid inlet 211, and the aerosol matrix in the second liquid storage tank 22 is configured to flow to the first liquid storage tank 21 under the action of gravity; or, when the switch 23 is in the second position, the liquid outlet 221 and the liquid inlet 211 are blocked.

[0032] When it is necessary to replenish the aerosol matrix in the first liquid storage tank 21, such as Figure 4 As shown, since the outlet 221 and the inlet 211 are arranged opposite to each other, the user can control the switch 23 to be in the first position, so that the aerosol matrix in the second storage tank 22 can flow to the first storage tank 21 under the action of gravity to replenish the aerosol matrix in the first storage tank 21. When it is not necessary to replenish the aerosol matrix in the first storage tank 21, such as... Figure 5 As shown, the user can control the switch 23 to be in the second position, so that the liquid outlet 221 and the liquid inlet 211 are blocked, thereby preventing the aerosol matrix from flowing into the first liquid storage tank 21.

[0033] This application incorporates a first liquid storage chamber 21 and a second liquid storage chamber 22 within the atomizing device. This allows the second liquid storage chamber 22 to replenish the aerosol matrix to the first liquid storage chamber 21, eliminating the need for an external liquid storage bottle on the atomizing device. During replenishment, the user simply controls the flow rate of the aerosol matrix into the first liquid storage chamber 21 by adjusting the switch 23 to either the first or second position, making operation simple and convenient. Furthermore, by separating the first and second liquid storage chambers 21, the supply device 2 allows air from the first liquid storage chamber 21 to flow into the second liquid storage chamber 22 when replenishing the aerosol matrix. This reduces the pressure difference within the second liquid storage chamber 22, preventing leakage of the aerosol matrix due to excessive pressure difference. In addition, the switch 23 is located between the first liquid storage tank 21 and the second liquid storage tank 22, which can also prevent the switch 23 from occupying the capacity space of the first liquid storage tank 21 or the second liquid storage tank 22, thereby helping to increase the capacity of the liquid supply device 2 to store aerosol matrix.

[0034] Among them, such as Figure 2As shown, the bottom of the storage chamber in the second storage tank 22 may have an inclined portion 224, and the inclined direction of the inclined portion 224 is towards the outlet hole 221.

[0035] When the switch 23 is in the first position, since the inclined direction of the inclined part 224 is towards the liquid outlet 221, and the liquid outlet 221 is located at the bottom of the liquid storage chamber in the second liquid storage tank 22, the aerosol matrix in the second liquid storage tank 22 can flow to the liquid outlet 221 under the guidance of the inclined part 224, thereby avoiding the residual aerosol matrix in the second liquid storage tank 22 and improving the utilization rate of the aerosol matrix.

[0036] It is understood that the volume of the storage chamber in the second storage tank 22 can be larger than that in the first storage tank 21. For example, the volume of the storage chamber in the second storage tank 22 is 10 ml, and the volume of the storage chamber in the first storage tank 21 is 2 ml. When the aerosol matrix in the first storage tank 21 is completely atomized, the switch 23 is opened to replenish the liquid when needed, thus avoiding leakage caused by excessive residual aerosol matrix in the first storage tank 21. This application does not impose any special limitations on the specific capacity of the first storage tank 21 and the second storage tank 22.

[0037] Among them, such as Figure 3 As shown, the liquid supply device 2 may further include a liquid storage cap 24, allowing the first liquid storage tank 21 and the second liquid storage tank 22 to share the same liquid storage cap 24 for sealing. A separate sealing element may be provided between the liquid storage cap 24 and the first liquid storage tank 21 to prevent leakage of the aerosol matrix from the first liquid storage tank 21; a separate sealing element may also be provided between the liquid storage cap 24 and the second liquid storage tank 22 to prevent leakage of the aerosol matrix from the second liquid storage tank 22. In other embodiments, the first liquid storage tank 21 and the second liquid storage tank 22 may each be configured as independent liquid storage tanks, thus eliminating the need to share the same liquid storage cap 24. This application does not impose any special limitations on the specific structure of the first liquid storage tank 21 and the second liquid storage tank 22.

[0038] In some embodiments, such as Figure 3 and Figure 8 As shown, the switch 23 may include a separator 231, and the side wall of the separator 231 is provided with a liquid passage hole 232 passing through the separator 231; when the separator 231 is in a first position, at least a portion of the liquid passage hole 232 is connected to the liquid inlet hole 211 and the liquid outlet hole 221; or, when the separator 231 is in a second position, the side wall of the separator 231 is configured to block the liquid inlet hole 211 and / or the liquid outlet hole 221.

[0039] When the switch 23 needs to be opened, it is only necessary to connect the liquid passage 232 on the separator 231 with the liquid inlet 211 and the liquid outlet 221. The opening degree of the liquid passage 232 between the liquid inlet 211 and the liquid outlet 221 can also be adjusted to regulate the flow rate of the aerosol matrix into the first storage chamber 21, thus preventing the user from being unable to control the replenishment flow rate due to excessively high flow rate. When the switch 23 needs to be closed, it is only necessary to offset the liquid passage 232 on the separator 231 from the liquid inlet 211 and the liquid outlet 221 respectively. At this time, the side wall of the separator 231 can block the liquid inlet 211 and / or the liquid outlet 221, thereby preventing the aerosol matrix from flowing from the second storage chamber 22 into the first storage chamber 21. The liquid passage 232 can be set as a circular hole or an oblong hole, etc., and this application does not impose any special restrictions on the specific shape of the liquid passage 232.

[0040] In other embodiments, the switch 23 may also include a flexible hose and a clamp, with the hose connecting the inlet port 211 and the outlet port 221, and the clamp holding the hose in place. When the switch 23 needs to be opened, simply opening the clamp connects the inlet port 211 and the outlet port 221. The flow rate of the aerosol matrix into the first storage chamber 21 can also be adjusted by regulating the clamping force of the clamp on the hose. When the switch 23 needs to be closed, simply closing the clamp blocks the connection between the inlet port 211 and the outlet port 221. This application does not impose any special limitations on the specific structure of the switch 23.

[0041] When the switch element 23 adopts a separator 231 structure with a liquid passage 232, such as Figures 6 to 8 As shown, the inlet hole 211 can be set on the wall of the first liquid storage chamber 21, the outlet hole 221 can be set on the bottom of the wall of the second liquid storage chamber 22, and the separator 231 is set between the first liquid storage chamber 21 and the second liquid storage chamber 22. The separator 231 is configured to be able to move relative to each other along the first direction to be in the first position or the second position.

[0042] For example, the shape of the separator 231 can be set as a plate. Figures 1 to 3 As shown, the atomizing device can be shaped like a cuboid with a length direction, a thickness direction, and a height direction. For ease of description, the X direction will be defined as the length direction or second direction of the atomizing device, the Y direction as the thickness direction or third direction, and the Z direction as the height direction, axial direction, or first direction. The first liquid storage chamber 21 and the second liquid storage chamber 22 can be spaced apart along the X direction, and the separator 231 can be a plate-like structure in the YZ plane. When it is necessary to open or close the switch 23, it is only necessary to move the separator 231 along the Z direction to connect or close the liquid inlet 211 and the liquid outlet 221.

[0043] It should be noted that the position of the liquid inlet 211 on the first liquid storage chamber 21 can vary depending on the structure of the atomizing core assembly 3. For example, when the heating element is covered with a large volume of outer cotton, the outer cotton can absorb a large amount of aerosol matrix for heating and atomization. In this case, the liquid inlet 211 can be located at the bottom of the chamber wall of the first liquid storage chamber 21. When the outer cotton covering the heating element is small, the liquid inlet 211 can be located at the top or middle of the chamber wall of the first liquid storage chamber 21, so that the aerosol matrix flows into the heating element for heating and atomization within the first liquid storage chamber 21. This application does not impose any special restrictions on the specific position of the liquid inlet 211 on the first liquid storage chamber 21.

[0044] In other embodiments, the separator 231 can also be cylindrical, with the liquid passage 232 extending radially through the separator 231. When the switch 23 needs to be opened or closed, simply rotate the separator 231 to position the liquid passage 232 to connect or close the inlet 211 and outlet 221, thus achieving the same function of opening or closing the switch 23. This application does not impose any special limitations on the specific shape of the separator 231.

[0045] It is understandable that when the separator 231 is plate-shaped, the liquid passage 232 can be located near the bottom of the separator 231, with the plate surface above the liquid passage 232 blocking the liquid inlet 211 and the liquid outlet 221. When the switch 23 needs to be opened, moving the separator 231 upward in the Z direction will connect the liquid inlet 211 and the liquid outlet 221. Alternatively, the liquid passage 232 can be located away from the bottom of the separator 231, with the plate surface below the liquid passage 232 blocking the liquid inlet 211 and the liquid outlet 221. When the switch 23 needs to be opened, moving the separator 231 downward in the Z direction will connect the liquid inlet 211 and the liquid outlet 221. This application does not impose any special restrictions on the direction of movement of the separator 231 when it is in the open or second position.

[0046] When the shape of the separator 231 is plate-shaped, such as Figure 6 and Figure 7 As shown, the liquid supply device 2 also includes a first sealing element 212 and a second sealing element 222; the first sealing element 212 is disposed between the liquid inlet hole 211 and the side wall of the separator 231, and the second sealing element 222 is disposed between the liquid outlet hole 221 and the other side wall of the separator 231.

[0047] Therefore, the first seal 212 can seal the gap between the wall of the first liquid storage tank 21 and the side wall of the separator 231, and the second seal 222 can seal the gap between the wall of the second liquid storage tank 22 and the other side wall of the separator 231, thereby preventing the aerosol matrix from leaking from the inlet hole 211 and / or the outlet hole 221 and flowing in from the gap between the tank wall and the side wall of the separator 231, thus improving the sealing performance of the liquid supply device 2. At the same time, the first seal 212 and the second seal 222 also have a clamping function on the plate-shaped separator 231 to fix the separator 231, thereby maintaining the relative position of the liquid passage hole 232 with the inlet hole 211 and the outlet hole 221 respectively after the separator 231 moves.

[0048] To facilitate user replacement of the second liquid storage tank 22, such as Figure 6 and Figure 7 As shown, the liquid supply device 2 may further include a first support 213, a connector 223, and a connecting groove 214; the first support 213 is connected to the first liquid storage tank 21, one of the connector 223 and the connecting groove 214 may be disposed on the first support 213, and the other of the connector 223 and the connecting groove 214 may be disposed on the second liquid storage tank 22; wherein, the relative position of the second liquid storage tank 22 and the first support 213 is defined by the connector 223 and the connecting groove 214.

[0049] For example, the connecting groove 214 can be disposed on the first bracket 213, and the connector 223 can be disposed at the bottom of the second liquid storage tank 22. The connecting groove 214 and the connector 223 can be configured as a detachable connection. When the second liquid storage tank 22 is installed on the first bracket 213, the second liquid storage tank 22 is relatively fixed to the first bracket 213, thereby ensuring that the inlet hole 211 and the outlet hole 221 are relatively aligned. When the aerosol matrix in the second liquid storage tank 22 is used up, the second liquid storage tank 22 can be disassembled and replaced with a new one, thus meeting the user's needs for the aerosol matrix. Alternatively, the connecting groove 214 and the connector 223 can also be configured as a fixed connection, so that the second liquid storage tank 22 is relatively fixed to the first bracket 213 after installation. The connecting groove 214 can be configured as a sliding groove, threaded groove, or snap-fit ​​groove, etc., and correspondingly, the connector 223 can be configured as a slider, stud, or snap-fit, etc. This application does not impose any special restrictions on the specific structure of the connector 223 and the connecting groove 214. Of course, the connecting groove 214 can also be set on the second liquid storage tank 22, and the connector 223 can be set on the first support 213. This application does not impose any special restrictions on the specific location of the connector 223 and the connecting groove 214.

[0050] To ensure the direction of movement of the switch 23, such as Figure 6 and Figure 8As shown, the liquid supply device 2 may further include a guide member 215 and a guide groove 233; one of the guide member 215 and the guide groove 233 may be disposed on the first liquid storage tank 21 or the second liquid storage tank 22, and the other of the guide member 215 and the guide groove 233 may be disposed on the switch member 23; wherein, when the switch member 23 moves between the first position and the second position, the guide groove 233 is configured to restrict the movement path of the guide member 215.

[0051] For example, guide member 215 can be disposed on the outer wall of the first liquid storage tank 21, and guide groove 233 can be disposed on the separator 231. Guide member 215 can be configured as two protrusions arranged along the moving direction of separator 231, and guide groove 233 can be configured as a strip-shaped slit arranged along the moving direction of separator 231. When separator 231 moves to the point where one of the protrusions abuts against one end of the strip-shaped slit, switch member 23 is in a first position; when separator 231 moves to the point where the other protrusion abuts against the other end of the strip-shaped slit, switch member 23 is in a second position. Thus, through the cooperation of the protrusions and the strip-shaped slit, not only can the movement of separator 231 be guided, but the movement of separator 231 can also be limited in the first and second positions. In other embodiments, guide member 215 can also be configured as a sliding rod, with a sliding sleeve slidably connected to it, and guide groove 233 is a groove on the sliding sleeve, which can also guide the movement of switch member 23. This application does not impose any special restrictions on the specific structure of the guide member 215 and the guide groove 233.

[0052] Furthermore, the guide member 215 can also be disposed on the switch member 23, and the guide groove 233 can also be disposed on the outer wall of the first liquid storage tank 21; alternatively, the guide member 215 can also be disposed on the second liquid storage tank 22, and the guide groove 233 can also be disposed on the switch member 23; alternatively, the guide member 215 can also be disposed on the switch member 23, and the guide groove 233 can also be disposed on the second liquid storage tank 22. This application does not impose any special restrictions on the specific locations of the guide member 215 and the guide groove 233.

[0053] In some embodiments, such as Figure 6 , Figure 8 and Figure 9As shown, the liquid supply device 2 may further include an electromagnetic drive 234 and a second support 216. The electromagnetic drive 234 may include a base 2341, a magnetic element 2342, and a coil 2343. The second support 216 is connected to the first liquid storage tank 21 or the second liquid storage tank 22. The base 2341 is fixed relative to the second support 216. The magnetic element 2342 is movably disposed within the base 2341. The coil 2343 is installed within the base 2341 and wound around the periphery of the magnetic element 2342. The magnetic element 2342 is connected to the switch 23 and is configured to be driven by the magnetic field generated by the coil 2343 to move relative to the switch.

[0054] For example, the second bracket 216 can be connected to the first liquid storage tank 21, and the base 2341 can be connected and fixed to the second bracket 216 by means of snap-fit, screw-fit, or adhesive. A magnetic component 2342 is movably disposed within the base 2341, and a coil 2343 is wound around the periphery of the magnetic component 2342 and electrically connected to the circuit board 41. When the coil 2343 is energized, it generates a magnetic field, which drives the magnetic component 2342 to move relative to the base 2341 in the Z direction, thereby causing the magnetic component 2342 to move the switch component 23. The user only needs to control the energization or de-energization of the electromagnetic drive component 234 to control the opening or closing of the switch component 23, thereby controlling the start and stop of the aerosol matrix replenishment state, which is simple and convenient to operate. In addition, the second bracket 216 can also be connected to the second liquid storage tank 22, and the base 2341 can be connected and fixed to the second bracket 216. The structure of the electromagnetic drive component 234 is the same as in the above embodiment. This application does not impose any special restrictions on the specific location of the second support 216.

[0055] In other embodiments, the electromagnetic drive 234 can be replaced with an air pump to drive the movement of the switch 23. The air pump can drive the switch 23 to move by inputting or outputting air pressure. This application does not impose any special limitations on the specific device for driving the movement of the switch 23.

[0056] In addition, such as Figure 9 As shown, the electromagnetic drive unit 234 may also include an elastic element 2344; the elastic element 2344 may be connected between the base 2341 and the magnetic element 2342, and the magnetic element 2342 is configured to move from a second position to a first position under the elastic force of the elastic element 2344.

[0057] For example, when the user needs to open the switch 23, the coil 2343 is energized to drive the switch 23 to move downwards in the Z direction, connecting the liquid passage 232 with the liquid inlet 211 and the liquid outlet 221, thereby allowing the second liquid storage tank 22 to replenish the aerosol matrix to the first liquid storage tank 21. At this time, the switch 23 is in the first position, and the elastic element 2344 is in a stretched state and stores elastic potential energy. When the user needs to close the switch 23, the coil 2343 is de-energized, the elastic potential energy stored in the elastic element 2344 is released, and the switch 23 moves upwards in the Z direction under elastic action, thereby causing the liquid passage 232 to be misaligned with the liquid inlet 211 and the liquid outlet 221 respectively. At this time, the switch 23 is in the second position, and the first liquid storage tank 21 and the second liquid storage tank 22 are blocked. The elastic element 2344 can be a spring, sheet spring, or disc spring, etc., and this application does not impose any special restrictions on the specific structure of the elastic element 2344.

[0058] Therefore, the atomizing device can be configured to have switch 23 off under normal conditions (i.e., when coil 2343 is de-energized) and switch 23 on when the user is using it (i.e., when coil 2343 is energized), thus preventing leakage when the atomizing device is not in use. Furthermore, by using the elastic element 2344 to close switch 23, there is no need to design reverse current for the electromagnetic drive element 234, which helps to reduce the design and manufacturing process of the atomizing device.

[0059] 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.
