Description

Technical Field

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

[0002] The atomizing device atomizes the atomizing matrix into an aerosol through an atomizing component. The generated aerosol is then discharged from the outlet under the guidance of the atomizing air guide tube. Before being discharged, the aerosol may condense due to temperature changes, flow resistance, and other factors. The condensate is generally absorbed by absorbent cotton placed upstream of the airflow direction at the outlet to prevent the user from inhaling the condensate from the aerosol and affecting the taste.

[0003] However, the absorbent cotton has a limited capacity. When the atomizing device is used for a long time or when the generated aerosol itself contains a lot of water mist, the absorbent cotton is prone to oversaturation, causing condensation to overflow. Once the overflowing liquid accumulates to a certain extent, it will flow back into the atomizing chamber through the air outlet of the atomizing tube, and then mix with the atomizing matrix on the atomizing component. This changes the original composition ratio of the atomizing matrix, causing it to deteriorate and develop an off-flavor, which seriously affects the quality of the generated aerosol and the inhalation taste, thus reducing the user experience. Utility Model Content

Detailed Implementation

[0027] The technical solution of this application will be further described in detail below with reference to specific embodiments and accompanying drawings. In the following embodiments, many details are described in order to enable this application to be better understood. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by their components, materials, or methods.

[0028] To facilitate understanding of the technical solution of this application, the width direction of the atomizing device is defined as the X-axis, the thickness direction of the atomizing device is defined as the Y-axis, and the height direction of the atomizing device is defined as the Z-axis, which is consistent with the direction of gravity.

[0029] Please see Figures 1 to 2 In some embodiments of this application, an atomizing device (such as...) is provided. Figure 1 As shown in the figure, the atomizing device includes a receiving cavity 1, a first liquid suction component 2, a first atomizing component 3, an atomizing air guide tube 4, and a second liquid suction component 5. The receiving cavity 1 provides a receiving space, and the first liquid suction component 2 is disposed in the receiving space of the receiving cavity 1. The first liquid suction component 2 is used to absorb liquid in the airflow, and the first liquid suction component 2 is provided with an airflow channel 23 for the airflow to pass through.

[0030] The first atomizing component 3 is located below the first liquid absorption component 2 in the direction of gravity and is used to generate the first aerosol. The atomizing air guide tube 4 is configured to allow the first aerosol to flow to the airflow channel 23.

[0031] The second liquid-absorbing element 5 is disposed in the first atomizing assembly 3, and the second liquid-absorbing element 5 is at least partially surrounding the outer periphery of the air outlet end of the atomizing air guide tube 4. The second liquid-absorbing element 5 is configured to absorb the liquid overflowing from the first liquid-absorbing assembly 2.

[0032] During use, the first aerosol generated by the first atomizing component 3 flows to the airflow channel 23 under the guidance of the atomizing air guide tube 4. During this process, the first liquid absorption component 2 automatically absorbs the liquid in the airflow flowing through the airflow channel 23. The absorbed liquid includes the condensate formed by the condensation of the first aerosol, the water mist contained in the first aerosol itself, and the water mist contained in the airflow itself, etc., to prevent the liquid from being discharged with the first aerosol and inhaled by the user, thus forming a liquid absorption effect. The first atomizing component 3 is located below the first liquid absorption component 2 in the direction of gravity. The second liquid absorption component 5 is disposed in the first atomizing component 3. The liquid overflowing from the first liquid absorption component 2 after it becomes supersaturated will automatically flow to the second liquid absorption component 5 under the action of gravity and be absorbed by the second liquid absorption component 5. This makes the first liquid absorption component 2 and the second liquid absorption component 5 work together to form a dual liquid absorption effect, which significantly reduces the risk of the liquid overflowing from the first liquid absorption component 2 flowing back through the atomizing air guide tube 4. It avoids the problem of the atomizing matrix deteriorating and changing taste due to the backflow of condensate, which affects the quality of the generated aerosol and the inhalation taste. This ensures the quality of the first aerosol output by the atomizing device and the inhalation taste, and improves the user experience.

[0033] Please see Figure 2 In some embodiments, when the atomizing device is placed vertically, i.e. along the Z-axis, the receiving cavity 1 can be positioned above the first atomizing component 3, so that the first liquid suction component 2 is arranged at a higher position than the second liquid suction component 5, ensuring that the liquid overflowing from the first liquid suction component 2 will automatically flow to the second liquid suction component 5 under the action of gravity along the airflow channel 23, preventing the liquid overflowing from the first liquid suction component 2 from flowing back to the first atomizing component 3 through the atomizing air guide tube 4.

[0034] Please see Figure 3 In some embodiments, the first atomizing component 3 includes a first through hole 311 communicating with the airflow channel 23. The atomizing air guide tube 4 is at least partially located in the first through hole 311, and a liquid collection channel 10 is defined between the outer wall of the atomizing air guide tube 4 and the inner wall of the first through hole 311. The second liquid suction member 5 is at least partially abutted against the bottom of the liquid collection channel 10 for adsorbing the liquid guided by the liquid collection channel 10.

[0035] The liquid collection channel 10 provides a channel for the liquid accumulated in the airflow channel 23 to be transferred to the second liquid suction element 5. The second liquid suction element 5 is at least partially in contact with the bottom of the liquid collection channel 10, which facilitates the automatic transfer and adsorption of the liquid guided by the liquid collection channel 10 to the second liquid suction element 5 under the action of gravity. This improves the efficiency and reliability of the liquid adsorption of the second liquid suction element 5 and reduces the risk of the liquid accumulated at the bottom of the airflow channel 23 overflowing the top of the atomizing air guide tube 4 and flowing back.

[0036] Please see Figure 3 In some embodiments, the aperture of the first through hole 311 is smaller than the inner diameter of the airflow channel 23, that is, the inner diameter of the airflow channel 23 is larger than the outer diameter of the atomizing air guide tube 4, so as to ensure the airflow rate through the airflow channel per unit time and enable the first aerosol to be fully mixed with the air in the airflow.

[0037] Please see Figure 3 In some embodiments, the outlet end of the atomizing air guide tube 4 extends at least partially through the first through hole 311 to the airflow channel 23, that is, the top of the atomizing air guide tube 4 extends beyond the first through hole 311, so that the height of the inner peripheral wall of the liquid collection channel 10 is greater than the height of the outer peripheral wall of the liquid collection channel 10. This structure is conducive to accumulating more liquid in the airflow channel 23, preventing the accumulated liquid from easily overflowing the top of the atomizing air guide tube 4 and flowing back. It is also conducive to the transfer and adsorption of the liquid overflowing from the first liquid absorption component 2 to the second liquid absorption component 5 through the liquid collection channel 10, further reducing the risk of the liquid overflowing from the first liquid absorption component 2 flowing back through the atomizing air guide tube 4.

[0038] Please see Figure 1 , Figure 2 and Figure 5 In some embodiments, the atomizing device further includes an air outlet 61 and an air outlet pipe 62 (e.g., Figure 2 As shown in the diagram, the air outlet 61 is used for airflow discharge from the atomizing device. The air outlet 61 can be located at the upper end of the atomizing device for easy inhalation by the user. The air outlet pipe 62 is disposed in the receiving cavity 1, and the air outlet pipe 62 connects the air outlet end of the airflow channel 23 to the air outlet 61. At least a portion of the inner wall of the air outlet end of the airflow channel 23 is configured as a constriction structure 233 (e.g., ...). Figure 5 As shown in the diagram, the inner diameter of the constriction structure 233 gradually decreases from the upstream direction of the airflow (i.e., the end facing the atomizing air guide tube 4) to the downstream direction of the airflow (i.e., the end facing the air outlet 61), so that at least part of the inner wall of the air outlet end of the airflow channel 23 forms a structure similar to an inverted funnel. The inverted funnel-shaped constriction structure 233 facilitates the smooth discharge of airflow in the airflow channel 23 and makes the main body of the airflow channel 23 have a larger inner diameter than the air outlet tube 62.

[0039] Please see Figure 3In some embodiments, the air outlet pipe 62 extends at least partially into the airflow channel 23 via the constriction structure 233, that is, the air inlet end of the air outlet pipe 62 extends at least partially into the main body of the airflow channel 23, so that the outer wall of the air inlet end of the air outlet pipe 62 and the inner wall of the air outlet end of the airflow channel 23 define an annular cavity 20. During the flow of air in the airflow channel 23 from upstream (i.e., one end of the atomizing air guide pipe 4) to downstream (i.e., one end of the air outlet 61), at least part of the airflow will change its flow direction under the obstruction of the formed annular cavity 20, flow around to the air outlet pipe 62 and finally be discharged from the air outlet 61. This meandering flow pattern further promotes the condensation of liquid components in the airflow on the inner wall of the airflow channel 23 and the outer wall of the outlet pipe 62, thereby significantly reducing the risk of liquid components in the airflow condensing on the inner wall of the outlet pipe 62. On the one hand, it avoids the problem of condensate being discharged under the airflow and being inhaled by the user, and on the other hand, it also reduces the risk of condensate dripping directly onto the atomizing air guide pipe 4 along the inner wall of the outlet pipe 62.

[0040] Please see Figure 3 In some embodiments, the exhaust pipe 62 extends at least partially into the airflow channel 23 via the constriction structure 233, that is, the air inlet end of the exhaust pipe 62 extends at least partially into the main body of the airflow channel 23, so that the outer wall of the air inlet end of the exhaust pipe 62 and the inner wall of the air outlet end of the airflow channel 23 define the aforementioned annular cavity 20.

[0041] The outlet pipe 62 is coaxially arranged with the first through hole 311 and the atomizing air guide pipe 4. The outer diameter of the outlet pipe 62 is between the outer diameter of the atomizing air guide pipe 4 and the inner diameter of the first through hole 311. Since the outer wall of the air inlet end of the outlet pipe 62 and the inner wall of the air outlet end of the airflow channel 23 define the aforementioned annular cavity 20, it promotes the condensation of liquid components in the airflow on the outer wall of the outlet pipe 62. By limiting the outer diameter of the outlet pipe 62, the liquid condensed on the outer wall of the outlet pipe 62 can drip directly into the liquid collection channel 10 under the action of gravity and be absorbed by the second liquid suction component 5. This can delay the oversaturation time of the first liquid suction component 2, improve the service life of the first liquid suction component 2, and also reduce the accumulation of condensate in the airflow channel 23.

[0042] Please see Figure 4 In some embodiments, the first liquid-absorbing assembly 2 includes a first sealing member 21 and a first liquid-absorbing member 22. The first sealing member 21 has a first cavity 211 and a second cavity 212. The first cavity 211 is connected to a first through hole 311 and an air outlet pipe 62, and the second cavity 212 is connected to the first cavity 211. The first liquid-absorbing member 22 is housed in the second cavity 212, and at least a portion of the first liquid-absorbing member 22 and the first cavity 211 enclose the aforementioned airflow channel 23, so as to absorb liquid in the airflow flowing through the airflow channel 23.

[0043] The first sealing element 21 can be made of flexible materials such as silicone or rubber, and the first sealing element 21 at least partially conforms to the inner wall and bottom surface of the receiving cavity 1, and at least partially conforms to the outer wall surface of the air inlet end of the air outlet pipe 62, so as to ensure the airtightness of the airflow channel 23 connecting the atomizing air guide pipe 4 and the air outlet 61, and prevent the airflow in the airflow channel 23 from escaping between the outer wall of the first sealing element 21 and the inner wall of the receiving cavity 1, thus ensuring the sealing effect. Correspondingly, the first through hole 311 is provided through the bottom surface of the receiving cavity 1, and the first through hole 311 is located in the bottom region of the first cavity 211.

[0044] The first liquid-absorbing element 22 and the second liquid-absorbing element 5 can be manufactured using the same liquid-absorbing material or different liquid-absorbing materials; this application does not limit this. The liquid-absorbing material can be any one or more materials with liquid-absorbing properties, such as natural or non-natural porous fiber materials, porous ceramic materials, and polymer liquid-absorbing materials; this application does not limit this, as long as it can meet the liquid-absorbing requirements of the atomizing device.

[0045] Please see Figure 3 In some embodiments, the first through hole 311 penetrates the bottom surface of the receiving cavity 1, and the inner diameter of the end of the first through hole 311 facing the receiving cavity 1 gradually decreases from upstream to downstream in the liquid flow direction. In this embodiment, the atomizing device is placed vertically, and the liquid in the liquid collection channel 10 flows from top to bottom under the action of gravity. That is, the inner diameter of the upper end of the first through hole 311 facing the receiving cavity 1 gradually decreases from top to bottom, so that the upper inner wall of the outer peripheral wall of the liquid collection channel 10 forms a funnel-shaped guiding structure, which facilitates the collection of liquid accumulated in the airflow channel 23 into the liquid collection channel 10, and then guides it to the second liquid suction member 5 by the liquid collection channel 10, further reducing the accumulation of liquid in the airflow channel 23.

[0046] Please see Figures 2 to 3 In some embodiments, the first atomizing component 3 further includes a liquid replenishment chamber 31 and a second sealing element 32, wherein the liquid replenishment chamber 31 is provided with a first liquid storage chamber 312 (e.g., Figure 3 As shown in the figure, the first liquid storage chamber 312 is configured to store the first atomizing matrix, which is atomized to generate the first aerosol.

[0047] The first through hole 311 is opened on the top surface of the replenishment chamber 31, and the atomizing air guide tube 4 passes through the first liquid storage chamber 312. The second sealing member 32 seals the top surface of the first liquid storage chamber 312 and the replenishment chamber 31, as well as the outer wall of the atomizing air guide tube 4. The second sealing member 32 at least partially abuts against the bottom of the liquid collection channel 10 and wraps around at least part of the outer wall of the air outlet end of the atomizing air guide tube 4, forming a good seal between the outer wall of the atomizing air guide tube 4 and the first liquid storage chamber 312. This effectively prevents the liquid guided by the liquid collection channel 10 from flowing back to the first liquid storage chamber 312 along the outer wall of the atomizing air guide tube 4, preventing the backflowing liquid from changing the composition ratio of the first atomizing matrix in the first liquid storage chamber 312, avoiding the deterioration and off-flavor of the first atomizing matrix, and ensuring the quality and inhalation taste of the first aerosol.

[0048] In addition, the second seal 32 seals the first liquid storage chamber 312 and the receiving chamber 1, preventing the first atomized matrix in the first liquid storage chamber 312 from leaking into the receiving chamber 1 through the first through hole 311.

[0049] Please see Figure 6 In some embodiments, the second sealing member 32 is provided with a second through hole 321 and a second receiving groove 322. The second through hole 321 penetrates the second sealing member 32 and connects the first liquid storage chamber 312 and the first through hole 311. The atomizing air guide tube 4 passes through the second through hole 321 at least partially, and the outer wall of the atomizing air guide tube 4 is in close contact with at least a portion of the inner wall of the second through hole 321 to prevent the first atomizing matrix in the first liquid storage chamber 312 from leaking along the outer wall of the atomizing air guide tube 4. The second receiving groove 322 is disposed at one end of the second sealing member 32 that abuts against the top surface of the replenishment tank 31, and at least a portion of the hole wall of the second through hole 321 is located in the second receiving groove 322. The second liquid suction member 5 is received in the second receiving groove 322.

[0050] The upper wall of the second through hole 321 forms a flexible tube 3211 located in the second receiving groove 322. The outlet end of the atomizing air guide tube 4 passes through the flexible tube 3211 at least partially and is in close contact with the inner wall of the flexible tube 3211. The outer diameter of the flexible tube 3211 is larger than the outer diameter of the atomizing air guide tube 4 and smaller than the inner diameter of the first through hole 311, ensuring that the wall of the flexible tube 3211 has a certain thickness while leaving a certain space for the connection between the second liquid suction element 5 and the liquid collection channel 10.

[0051] Please see Figure 7The shape of the second suction member 5 matches the groove shape of the second receiving groove 322, and the second suction member 5 is provided with a third through hole 51 for the flexible tube 3211 of the second through hole 321 to pass through. After the second suction member 5 is assembled into the second receiving groove 322, the top surface of the second suction member 5 can be flush with the top surface of the second sealing member 32, ensuring the sealing effect of the second sealing member 32 on the top surfaces of the first liquid storage chamber 312 and the replenishment chamber 31. The second suction member 5 wraps around the outer periphery of the tube wall of the flexible tube 3211 through the third through hole 51, so that at least a part of the second suction member 5 can abut against the bottom of the liquid collection channel 10, ensuring the connection between the second suction member 5 and the liquid collection channel 10. In addition, the second liquid suction member 5 is isolated from the outer wall of the atomizing air guide tube 4 by a flexible tube 3211. Compared with the method of the second liquid suction member 5 directly wrapping the outer wall of the atomizing air guide tube 4, the sealing effect of the second sealing member 32 between the first liquid storage chamber 312 and the outer wall of the atomizing air guide tube 4 is significantly improved, and the liquid flowing down from the liquid collection channel 10 is prevented from flowing back to the first liquid storage chamber 312 along the outer wall of the atomizing air guide tube 4.

[0052] Please see Figure 1 and Figure 2 In some embodiments, the atomizing device further includes a housing 6, a first atomizing component 3 disposed in the housing 6, an air outlet 61 disposed at the upper end of the housing 6, and an air inlet 63 (e.g., at the lower end of the housing 6) is also provided. Figure 2 As shown in the diagram, the air inlet 63 is configured to allow external airflow to flow to the first atomizing component 3, so that the generated first aerosol is carried out by the airflow and sent to the atomizing air guide tube 4.

[0053] Please see Figure 2 The first atomizing component 3 further includes an atomizing chamber 33, a first liquid guiding component 34, and a heating component 35. The atomizing chamber 33 provides space for atomizing the first atomizing matrix. The first liquid guiding component 34 is configured to guide the first atomizing matrix stored in the first liquid storage chamber 312 to the atomizing chamber 33. The atomizing chamber 33 has an atomizing cavity 331, which forms a liquid path communication with the first liquid guiding component 34, and also forms an air path communication with the air inlet 63 and the atomizing air guide pipe 4. The heating component 35 is disposed in the atomizing cavity 331 and is used to heat and atomize the first atomizing matrix to generate a first aerosol. The generated first aerosol is carried by the airflow and sent to the airflow channel 23 through the atomizing air guide pipe 4. After being absorbed by the first liquid suction component 22, it is discharged through the air outlet pipe 62 and the air outlet 61.

[0054] The heating component 35 atomizes the first atomizing matrix by heating, resulting in a relatively high-temperature first aerosol. As it flows through the atomizing air guide pipe 4, the airflow channel 23, and the air outlet pipe 62, it gradually forms condensate due to the decreasing temperature. The condensate mainly forms on the inner wall of the airflow channel 23 and the outer wall of the air inlet end of the air outlet pipe 62 that extends into the airflow channel 23. The condensate formed on the inner wall of the airflow channel 23 is first adsorbed by the first liquid absorber 22. The condensate formed on the outer wall of the air inlet end of the air outlet pipe 62 drips directly into the liquid collection channel 10 under gravity, and is then adsorbed by the second liquid absorber 5 at the bottom of the liquid collection channel 10. If the first liquid absorber 22 reaches saturation and can no longer adsorb liquid in the airflow, the excess liquid overflows and collects in the first through hole 311 under gravity, and is then guided by the liquid collection channel 10 to the second liquid absorber 5, achieving a dual liquid absorption effect.

[0055] In some other embodiments, the first atomizing component 3 may also use ultrasonic atomization to atomize the first atomizing matrix guided by the first liquid guide 34 and generate the first aerosol.

[0056] Please see Figure 2 and Figure 3 In some embodiments, the atomizing device further includes a second atomizing component 7, which is disposed in the housing 6 and is used to generate a second aerosol. The airflow channel 23 includes a first air inlet 231 and a second air inlet 232. The first air inlet 231 is configured to allow the first aerosol to flow into the airflow channel 23, and the second air inlet 232 is configured to allow the second aerosol to flow into the airflow channel 23.

[0057] When the first atomizing component 3 and the second atomizing component 7 operate simultaneously, both the first aerosol and the second aerosol enter the airflow channel 23 at the same time, forming a mixed aerosol. After the liquid in the mixed aerosol is absorbed by the first liquid absorber 22, the mixed aerosol is discharged through the air outlet pipe 62 and the air outlet 61, providing the user with two flavors of aerosol. When the first atomizing component 3 and the second atomizing component 7 operate independently, only the first aerosol or only the second aerosol enters the airflow channel 23. After the liquid in the first aerosol or the second aerosol is absorbed by the first liquid absorber 22, the first aerosol or the second aerosol is discharged through the air outlet pipe 62 and the air outlet 61, providing the user with a single flavor of aerosol.

[0058] Please see Figure 2 In some embodiments, the second atomizing component 7 includes a liquid storage component 71, a second liquid guiding component 72, and an ultrasonic transducer 73. The liquid storage component 71 can be arranged side by side with the first atomizing component 3 in the X-axis direction. The liquid storage component 71 is provided with a second liquid storage chamber 711, which is configured to store a second atomizing matrix. The second atomizing matrix can be the same type as the first atomizing matrix or it can be different from the first atomizing matrix.

[0059] The second liquid guiding element 72 is at least partially located in the second liquid storage chamber 711 for guiding the second atomizing matrix.

[0060] An ultrasonic transducer 73 is disposed in the receiving cavity 1, and the ultrasonic transducer 73 at least partially abuts against the second liquid guide 72 for ultrasonic atomization of the second atomizing matrix.

[0061] The second atomizing component 7 uses an ultrasonic transducer 73 disposed in the receiving cavity 1 to ultrasonically atomize the second atomizing matrix and generate a second aerosol. The second aerosol is generated in the receiving cavity 1. During use, the user draws air out through the mouth outlet 61, creating a negative pressure inside the atomizing device. External airflow flows from the air inlet 63 to the atomizing chamber 331 of the first atomizing component 3, and then, guided by the atomizing air guide tube 4, enters the airflow channel 23 of the first liquid absorption component 2 through the first air inlet 231. Because the airflow channel 23 is under negative pressure, during the airflow discharge through the air outlet 62 and the air outlet 61, the generated second aerosol can be used to flow into the airflow channel 23 through the second air inlet 232 and finally be discharged with the airflow.

[0062] The second aerosol generated by ultrasonic atomization contains a large amount of water mist. As the second aerosol flows through the airflow channel 23, the water mist is adsorbed and removed by the first liquid suction element 22. After the first liquid suction element 22 reaches saturation, the remaining water mist condenses on the inner wall of the airflow channel 23 and the outer wall of the air inlet end of the air outlet pipe 62 extending into the airflow channel 23. Under the action of gravity, it flows to the first through hole 311 or drips directly into the liquid collection channel 10, and is then guided by the liquid collection channel 10 to the second liquid suction element 5, achieving a dual liquid suction effect. This solves the problem that the aerosol generated by ultrasonic atomization has a large water mist content, which easily leads to condensate backflow due to oversaturation of the liquid suction element, thus affecting the quality of the aerosol and the sucking taste.

[0063] Please see Figure 3 In some embodiments, a mounting base 11 is provided in the receiving cavity 1, and the mounting base 11 is located on one side of the first liquid suction assembly 2. The second air inlet end 232 of the airflow channel 23 is connected to the mounting base 11 along the X-axis. An ultrasonic transducer 73 is disposed in the mounting base 11, and the ultrasonic transducer 73 vibrates under the spatial constraint of the mounting base 11 to ultrasonically atomize the second atomizing matrix guided on the second liquid guide 72.

[0064] The liquid storage component 71 is rotatably connected to the housing 6. The liquid storage component 71 has at least two second liquid storage chambers 711. The number of second liquid guiding components 72 matches the number of second liquid storage chambers 711, with at least a portion located in the corresponding second liquid storage chamber 711 and at least a portion located on the side of the mounting base 11 facing away from the airflow channel 23. Different second liquid storage chambers 711 can store different flavored second atomizing substrates. Users can switch the second liquid guiding components 72 that abut against the ultrasonic transducer 73 by rotating the liquid storage component 71, thereby changing the flavor of the generated second aerosol. This satisfies users' needs for independently switching between multiple flavored aerosols and improves the user experience.

[0065] Please see Figure 3 In some embodiments, the air outlet pipe 62 has a notch 621 at the air inlet end that extends into the airflow channel 23. This notch 621 is located on the sidewall of the air outlet pipe 62 facing the second air inlet end 232, preventing the pipe wall of the air outlet pipe 62 from creating significant resistance to the second aerosol and allowing the second aerosol to flow smoothly through the notch 621 to the air outlet 61. Furthermore, the notch 621 also facilitates the entry of airflow that is blocked and detoured by the annular cavity 20 into the air outlet pipe 62, improving the suction resistance of the atomizing device and enhancing the user experience.

Those skilled in the art to which this application pertains can make several simple deductions, modifications, or substitutions based on the ideas presented in this application.
