Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and in particular to an aerosol generation apparatus. Background Technology

[0002] In one prior art example, an aerosol generating apparatus includes a main body and a cylinder storing an aerosol generating matrix. The cylinder is at least partially removably received by the main body. A planar transmitting antenna is disposed within the main body, and the cylinder is affixed with a tag for identification. When at least a portion of the cylinder is received by the main body, the main body and the cylinder communicate to obtain information from the tag. However, the above solution places strict requirements on the relative positions of the planar transmitting antenna and the tag. For cylinders capable of rotating around a rotation axis or receiving the aerosol at any angle, if the relative positions of the planar transmitting antenna and the tag are not in a preset position, the electromagnetic coupling strength between them is reduced, potentially leading to a communication failure between the main body and the cylinder, and consequently, the inability to identify the cylinder.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0034] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0035] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0036] Please see Figure 1 At least one embodiment of this application provides an aerosol generating apparatus, comprising:

[0037] The main body 10 is defined by a receiving cavity 101.

[0038] A cylinder 20 containing an aerosol generation matrix is ​​at least partially removably received within a receiving cavity 101, and a label 30 for identifying the cylinder 20 is provided on the outer surface of the cylinder 20.

[0039] The cylinder 20 is configured in a cylindrical shape to store the aerosol generation matrix. In one embodiment, an NFC tag for identifying the cylinder 20 is disposed on the outer surface of the cylinder 20. The NFC tag includes a tag antenna and a flexible substrate for carrying the tag antenna. Thus, utilizing the tensile properties of the flexible substrate, the NFC tag can be configured into a curved shape.

[0040] Please see Figure 2 The label 30 surrounds at least a portion of the outer surface of the cylinder 20.

[0041] It can be seen that the area of ​​tag 30 is less than or equal to the area of ​​the outer surface of cylinder 20. Based on actual requirements, the number of turns and shape of the tag antenna are rationally designed to select a tag 30 of appropriate size.

[0042] The transmitting antenna 40 is configured to surround the receiving cavity 101, and when at least a portion of the tube 20 is received within the receiving cavity 101, the radial projection of the tag 30 along the receiving cavity 101 lies within the area of ​​the transmitting antenna 40.

[0043] Please refer to the following: Figure 3 The transmitting antenna 40 includes: a flexible substrate 41 surrounding the receiving cavity 101; and a coil 42 disposed on the flexible substrate 41. Thus, utilizing the tensile properties of the flexible substrate 41, the transmitting antenna 40 can be configured into a curved shape. In other embodiments, the coil 42 may be disposed directly around the receiving cavity 101.

[0044] The main control circuit 50 is electrically connected to the transmitting antenna 40 and is configured to transmit radio frequency signals through the transmitting antenna 40, thereby achieving communication with the tag 30 through electromagnetic coupling.

[0045] Please refer to the following: Figure 4 The tube 20 is configured to rotate within the receiving cavity 101, and the transmitting antenna 40 is configured to move around the trajectory of the tag 30.

[0046] The transmitting antenna 40 is arranged around the receiving cavity 101, so that when the cylinder 20 is configured to rotate within the receiving cavity 101, the transmitting antenna 40 is configured to move around the trajectory of the tag 30. Furthermore, since the radial projection of the tag 30 along the receiving cavity 101 lies within the area of ​​the transmitting antenna 40 when at least a portion of the cylinder 20 is received within the receiving cavity 101, the main control circuit 50 can communicate with the tag 30 via electromagnetic coupling regardless of any angle the cylinder 20 rotates within the receiving cavity 101, thereby identifying the cylinder 20 that is at least partially removably received within the receiving cavity 101.

[0047] In some embodiments, the cylinder 20 is rotatable within the receiving cavity 101 between a first position and a second position, and when the cylinder 20 is in the first position and the second position, the projected area of ​​the tag 30 on the transmitting antenna 40 remains unchanged, or the distance between the tag 30 and the transmitting antenna 40 remains substantially unchanged.

[0048] It is known that the coupling strength between the transmitting antenna 40 and the tag 30 is inversely proportional to the distance and directly proportional to the projected area. It can be deduced that the larger the projected area of ​​the tag 30 on the transmitting antenna 40, the smaller the distance between the tag 30 and the transmitting antenna 40, the stronger the coupling signal between the tag 30 and the transmitting antenna 40, and the more reliable the communication between them.

[0049] In some embodiments, during the rotation of the cylinder 20, the projected area of ​​the tag 30 on the transmitting antenna 40 is maximized and remains constant, and / or the distance between the tag 30 and the transmitting antenna 40 is minimized and remains constant.

[0050] In one embodiment, the first position refers to a horizontal position, and the second position refers to a vertical position. The cylinder 20 is rotatable within the receiving cavity 101 between the first and second positions, and the cylinder 20 is configured to rotate 360 ​​degrees within the receiving cavity 101. In this configuration, the cylinder 20 includes four rotational positions, with a rotation angle of 90 degrees between any two adjacent rotational positions. Based on this, the cylinder 20 and the receiving cavity 101 are coaxial, and the transmitting antenna 40 surrounds the receiving cavity 101. Therefore, when the cylinder 20 is in the first and second positions, the projected area of ​​the tag 30 on the transmitting antenna 40 remains unchanged, or the distance between the tag 30 and the transmitting antenna 40 remains unchanged.

[0051] In another embodiment, the first position refers to a horizontal position and the second position refers to a vertical position. The cylinder 20 is rotatable within the receiving cavity 101 between the first and second positions, and the cylinder 20 is configured to rotate 90 degrees within the receiving cavity 101. In this case, the cylinder 20 includes two rotational positions, and the cylinder 20 switches between the two rotational positions by rotating 90 degrees.

[0052] In other embodiments, the cylinder 20 has five or more rotational positions, is capable of rotating between these positions within the receiving cavity 101, and is configured to rotate 360 ​​degrees within the receiving cavity 101. As an example, the cylinder 20 has six rotational positions, with equal rotation angles between adjacent positions, resulting in a rotation angle of 60 degrees. As another example, the cylinder 20 has twelve rotational positions, with equal rotation angles between adjacent positions, resulting in a rotation angle of 10 degrees. In still other embodiments, during one complete rotation of the cylinder 20 within the receiving cavity 101, at least two rotational positions have unequal rotation angles.

[0053] Please see Figure 2 and Figure 5 The aerosol generating device also includes at least two first electrode groups 11, which are disposed at the bottom of the receiving cavity 101 and connected to the main control circuit 50; the cylinder 20 includes a second electrode group 21, which is electrically connected to one of the first electrode groups 11 when the cylinder 20 is in the first position or the second position.

[0054] In some embodiments, the aerosol generating device includes a first electrode group 11a and a first electrode group 11b disposed at the bottom of the receiving cavity 101, and the cylinder 20 includes a second electrode group 21. The first electrode group 11a includes electrode 11a+ and electrode 11a-, the first electrode group 11b includes electrode 11b+ and electrode 11b-, and the second electrode group 21 includes electrode 21a+ and electrode 21a-.

[0055] In some embodiments, the first electrode group 11 includes a spring pin, and the second electrode group 21 includes a contact.

[0056] Assume the first position refers to a horizontal position and the second position refers to a vertical position. The cylinder 20 is rotatable within the receiving cavity 101 between the first and second positions, and the cylinder 20 is configured to rotate 360 ​​degrees within the receiving cavity 101. In this case, the cylinder 20 includes four rotational positions, with a rotation angle of 90 degrees between any two adjacent rotational positions. Correspondingly, the first position includes a first rotational position and a third rotational position, and the second position includes a second rotational position and a fourth rotational position. The cylinder 20 is configured to rotate within the receiving cavity 101 in the sequence of the first rotational position, the second rotational position, the third rotational position, and the fourth rotational position.

[0057] Based on the above, electrodes 11a+ and 11b+ in the first electrode group 11a and the first electrode group 11b are connected to the positive terminal of the power supply, and electrodes 11a- and 11b- are connected to the negative terminal of the power supply.

[0058] When the cylinder 20 is in the first rotational position, the second electrode group 21 is electrically connected to the first electrode group 11a. Specifically, electrode 21a+ is connected to the positive terminal of the power supply through electrode 11a+, and electrode 21a- is connected to the negative terminal of the power supply through electrode 11a-. When the cylinder 20 is in the second rotational position, the second electrode group 21 is electrically connected to the first electrode group 11b. Specifically, electrode 21a+ is connected to the positive terminal of the power supply through electrode 11b+, and electrode 21a- is connected to the negative terminal of the power supply through electrode 11b-. When the cylinder 20 is in the third rotational position, the second electrode group 21 is electrically connected to the first electrode group 11a. Specifically, electrode 21a+ is connected to the negative terminal of the power supply through electrode 11a-, and electrode 21a- is connected to the positive terminal of the power supply through electrode 11a+. When the cylinder 20 is in the fourth rotational position, the second electrode group 21 is electrically connected to the first electrode group 11b. Specifically, electrode 21a+ is connected to the negative terminal of the power supply through electrode 11b-, and electrode 21a- is connected to the positive terminal of the power supply through electrode 11b+.

[0059] In some embodiments, the aerosol generating apparatus further includes a first holding mechanism 12, and the cylinder 20 includes a second holding mechanism 22. When the cylinder 20 is received in the receiving cavity 101 and the second electrode group 21 is electrically connected to one of the first electrode groups 11, the first holding mechanism 12 and the second holding mechanism 22 cooperate with each other to hold the cylinder 20 in a first position or a second position.

[0060] In some embodiments, the first holding mechanism 12 includes magnets disposed around at least two first electrode groups 11, and the second holding mechanism 22 includes magnets disposed around a second electrode group 21.

[0061] As an example, the magnets of the first holding mechanism 12 are spaced apart between at least two electrodes of the first electrode group 11. The magnet connection lines of the second holding mechanism and the positive and negative pole connection lines of the second electrode group 21 intersect at a point.

[0062] In some embodiments, the aerosol generating apparatus includes a plurality of cylinders 20, and the number of transmitting antennas 40 is the same as the number of cylinders 20, with each transmitting antenna 40 surrounding a corresponding receiving cavity 101 for receiving cylinders 20.

[0063] It is understood that the aerosol generating device body 10 defines multiple receiving cavities 101, each transmitting antenna 40 is arranged around the corresponding receiving cavity 101, and each cylinder 20 has a label 30 for identifying the cylinder 20 on its outer surface. The multiple cylinders 20 are at least partially removably received within the receiving cavity 101. Based on this, the main control circuit 50 is electrically connected to the multiple transmitting antennas 40. When it is necessary to identify one of the cylinders 20, the main control circuit 50 selects to send a radio frequency signal to the corresponding transmitting antenna 40, thereby achieving communication through electromagnetic coupling with the label 30 on the outer surface of the cylinder 20.

[0064] Please see Figures 5 to 7 The main body 10 includes an annular wall 13, the inner surface of the annular wall 13 is used to define the receiving cavity 101, the transmitting antenna 40 surrounds the outer surface of the annular wall 13, and the thickness between the inner surface and the outer surface of the annular wall 13 is less than 1 cm.

[0065] In this embodiment, ignoring the gap between the tag 30 and the annular wall 13, the distance between the tag 30 and the transmitting antenna 40 is approximately equal to the thickness between the inner and outer surfaces of the annular wall 13. This distance satisfies the requirement that the main control circuit 50 transmits radio frequency signals through the transmitting antenna 40, thereby achieving communication with the tag 30 through electromagnetic coupling.

[0066] In some embodiments, the cylinder 20 further includes a fastener 23, which is disposed around the label 30 for securing the label 30.

[0067] In this embodiment, ignoring the gap between the tag 30 and the fixing member 23 and the gap between the fixing member 23 and the annular wall 13, the distance between the tag 30 and the transmitting antenna 40 is approximately equal to the sum of the thickness between the inner and outer surfaces of the annular wall 13 and the thickness between the inner and outer surfaces of the fixing member 23. This distance satisfies the requirement that the main control circuit 50 transmits radio frequency signals through the transmitting antenna 40, thereby achieving communication with the tag 30 through electromagnetic coupling.

[0068] Please refer to it again. Figure 1 The aerosol generating device also includes: a power supply component 60, which is connected to the main control circuit 50 and is used to provide power; the power supply component 60, the transmitting antenna 40 and the main control circuit 50 are disposed within the main body 10.

[0069] In summary, the aerosol generating device provided in this application is configured with a transmitting antenna surrounding the receiving cavity. When at least a portion of the tube is received in the receiving cavity, the projection of the tag along the radial direction of the receiving cavity is located within the area of ​​the transmitting antenna. This ensures that the main body and the tube can communicate when at least a portion of the tube is removably received in the receiving cavity, thereby improving the reliability of the tube's identification.
