Description

[0024] Furthermore, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments.

Therefore, the various sequences presented in the specification and drawings are intended merely to describe particular embodiments clearly, and are not to be construed as limiting unless otherwise explicitly stated.

[0025] The ordinal terms used herein for components, such as "first," "second," etc., are merely for distinguishing the described objects and do not imply any order or technical significance. Additionally, the terms "connected" or "coupled" unless otherwise specified, encompass both direct and indirect connections (or couplings).

[0026] Referring to FIGs. 1 to 5, in an embodiment, an electronic vaporization device is provided. The electronic vaporization device mainly includes a vaporization assembly 1, an in-place sensor 2, and a circuit board 3. The electronic vaporization device further includes a vaporization housing 4, within which the vaporization assembly 1, the in-place sensor 2, and the circuit board 3 are installed.

[0027] The vaporization housing 4 may be an integrated structure or may be formed by assembling multiple housing components. A portion of the vaporization housing 4 may be configured as a detachable structure, allowing the vaporization housing 4 to be opened by removing the detachable portion, so that internal components such as the vaporization assembly 1, the in-place sensor 2, and the circuit board 3 may be replaced or maintained.

[0028] The vaporization housing 4 includes an accommodation cavity 41 and is provided with an insertion port 42 on a side surface at one end. The vaporization assembly 1 includes a vaporization chamber 10 having a first end and a second end opposite to each other. The first end of the vaporization chamber 10 is provided with an opening for insertion of a vaporization substrate 6. The end face or axial side of the second end of the vaporization chamber 10 is provided with an air inlet for introducing air into the vaporization chamber 10. The opening of the vaporization chamber 10 is axially aligned and in communication with the insertion port 42, so that a user may insert the vaporization substrate 6 into the vaporization chamber 10 via the insertion port 42.

[0029] The vaporization assembly 1 mainly includes a first mounting seat 11, a heating tube 12, and a second mounting seat 13. The first mounting seat 11 and the second mounting seat 13 are both cylindrical structures with through-holes. One end of the heating tube 12 is sealingly and fixedly connected to the first mounting seat 11, and the other end is sealingly and fixedly connected to the second mounting seat 13. The first mounting seat 11, the heating tube 12, and the second mounting seat 13 are sequentially connected to form the vaporization chamber 10. The through-hole in the first mounting seat 11 defines the first end of the vaporization chamber 10 and is located near the insertion port 42, forming the opening of the vaporization chamber 10. The through-hole in the second mounting seat 13 defines the second end of the vaporization chamber 10 and is located away from the insertion port 42, forming the air inlet of the vaporization chamber 10.

[0030] The heating tube 12 may include a metal tube and a heating element. The heating element may be attached to the circumferential outer surface or the axial inner surface of the metal tube, and is configured to heat the metal tube. Such a heating tube 12 is a resistive heating structure. In other embodiments, the heating tube 12 may include a metal tube and an electromagnetic induction coil. The electromagnetic induction coil is disposed on the circumferential outer side of the metal tube and is configured to heat the metal tube by electromagnetic induction. Such a heating tube 12 constitutes an electromagnetic heating structure.

[0031] In this embodiment, the in-place sensor 2 is installed within the accommodation cavity 41 of the vaporization housing 4 and located outside the vaporization chamber 10. A through hole is formed in the side wall of the vaporization chamber 10, through which the in-place sensor 2 detects whether a vaporization substrate 6 is inserted.

[0032] In this embodiment, two in-place sensors 2 are provided: one is arranged at the first end of the vaporization chamber 10, and the other at the second end. The in-place sensor 2 at the first end detects whether the vaporization substrate 6 is inserted into the vaporization chamber 10 and whether it has been fully removed. The in-place sensor 2 at the second end detects whether the vaporization substrate 6 is fully inserted into the bottom of the vaporization chamber 10, i.e., whether it is properly positioned, and whether it has been removed from the bottom.

[0033] The two in-place sensors 2 function like two switches connected in series on a control circuit. When both sensors detect the presence of the vaporization substrate 6, the control circuit is closed, triggering the vaporization assembly 1 to begin heating the vaporization substrate 6. If either sensor does not detect the substrate, the circuit remains open, and the vaporization assembly 1 stops heating.

[0034] Using two in-place sensors 2 improves the accuracy of preventing false activation. For example, if the vaporization substrate 6 is inserted but not fully seated, the second-end sensor 2 will not be triggered, and the system will not start heating or will stop heating-thus avoiding activation in cases of partial or improper insertion and further reducing false triggering probability.

[0035] In other embodiments, more in-place sensors 2 can be used. Multiple sensors can be arranged at different axial positions along the vaporization chamber 10 to further reduce the chance of false activation.

[0036] In this embodiment, both the first mounting seat 11 and the second mounting seat 13 are provided with radial through holes. The in-place sensor 2 can be a photoelectric sensor (e.g., laser sensor). Located outside the through holes, the in-place sensor 2 interfaces with them. The sensor has both an emitter and a receiver: the emitter emits a detection beam, and the receiver collects the reflected beam. The circuit board 3 calculates the presence of the vaporization substrate 6 inside the vaporization chamber 10 based on the time delay between emission and reception. When the substrate is not inserted, the beam enters the chamber 10 and reflects off the inner wall. The reflected beam is collected by the receiver, and the time difference is relatively large. When the vaporization substrate 6 is inserted, the beam reflects off the substrate instead, and the time difference is relatively small.

[0037] In this embodiment, the in-place sensor 2 can be directly mounted on the circuit board 3, which is arranged parallel to the axis of the vaporization chamber 10. The two sensors 2 are mounted vertically on the circuit board 3, with their detection direction perpendicular to the axis of the chamber, i.e., they emit light radially into the vaporization chamber 10.

[0038] In other embodiments, the in-place sensor 2 can also be mounted on a support bracket fixed inside the accommodation cavity 41, and electrically connected to the circuit board 3 via cable. This structure allows for more flexible positioning of the circuit board 3 within the accommodation cavity 41.

[0039] The operation logic for using two in-place sensors 2 to control heating activation and deactivation is as follows: As shown in FIGs. 2 and 3: The insertion states of the vaporization substrate 6 include partially and fully inserted states. Initially, the vaporization substrate 6 is in a partially inserted state-at this point, the first-end sensor 2 detects the presence of the substrate at the opening of the chamber 10, but the second-end sensor 2 does not detect the substrate at the bottom. Heating does not start. When the vaporization substrate 6 is fully inserted, both sensors 2 detect it, and heating is triggered.

[0040] As shown in FIGs. 4 and 5: During removal, the vaporization substrate 6 is initially in a partially removed state. The first-end sensor 2 still detects the substrate at the opening, while the second-end sensor 2 no longer detects it at the bottom. Heating is then stopped-thus, partial removal of the vaporization substrate 6 will automatically stop heating, even if it is not completely withdrawn.

[0041] In this embodiment, the electronic vaporization device, by providing an in-place sensor 2 on the exterior of the vaporization chamber 10, detects whether the vaporization substrate 6 is inserted. The in-place sensor 2 acts as a trigger switch-when the substrate is inserted, it triggers heating; when removed, it triggers shutdown. This ensures that heating starts automatically when the substrate is inserted, and stops automatically when removed. It avoids false triggering from physical buttons, improves heating efficiency, and conserves energy.

[0042] As shown in FIG. 6: In another embodiment, the device may include only one in-place sensor 2, located at the bottom of the vaporization chamber 10. When the vaporization substrate 6 is fully inserted, the sensor 2 detects it and triggers heating; when removed, the sensor 2 no longer detects it and triggers shutdown. This bottom-mounted sensor 2 also prevents false starts, similar to traditional mechanical buttons.

[0043] As shown in FIG. 1: In an embodiment, a light-transmitting element 14 such as a lens or light guide column may be installed within the through holes of the first and second mounting seats (11, 13). The in-place sensor 2 interfaces with the light-transmitting element 14, transmitting and receiving light through it. This setup channels the light more effectively and eliminates gaps between the sensor and mounting seat, reducing light scattering and improving detection accuracy.

[0044] In another embodiment, the emitting and receiving ends of the two sensors 2 are pressed against the outer surfaces of the first and second mounting seats (11, 13), or they are snapped into grooves formed on the outer surfaces, which are connected to the through holes. Alternatively, the sensors 2 may be inserted directly into the through holes. All of these configurations reduce gaps and enhance detection precision.

[0045] In yet another embodiment, the in-place sensor 2 can be a contact sensor. The trigger ends of the two sensors 2 are inserted into the mounting seats (11, 13), with portions extending into the vaporization chamber 10. When the vaporization substrate 6 is inserted, it contacts the trigger end, activating the sensor 2.

[0046] An embodiment may use multiple in-place sensors 2 of different types-for example, one photoelectric and one contact type. Using multiple sensor types ensures redundancy: if one fails, the other maintains detection accuracy.

[0047] As shown in FIG. 1: In an embodiment, the vaporization assembly 1 also includes an outer tube 15, with an inner diameter larger than the heating tube 12. The outer tube 15 is coaxially sleeved around the heating tube 12, extending at one end to form a sealed connection with the first mounting seat 11, and at the other end with the second mounting seat 13. The space between them forms a sealed heat insulation chamber, preventing heat from dissipating and improving heating efficiency while saving energy.

[0048] The outer tube 15 may be integrally formed with either or both of the mounting seats (11, 13), e.g., integrated with the first mounting seat 11 and connected to the second via interference fit or sealing element.

[0049] As shown in FIG. 7: In an embodiment, the device also includes a battery 5 mounted within the accommodation cavity 41 of the vaporization housing 4. The battery 5 is electrically connected to the circuit board 3, the vaporization assembly 1, and the in-place sensor 2. The circuit board 3 may also be connected to a charging port, which can be located on the side or bottom of the vaporization housing 4, enabling recharging of the battery 5.

[0050] In the above-mentioned embodiments, the descriptions of each embodiment have their own focuses. For the parts not elaborated in a certain embodiment, one can refer to the relevant descriptions of other embodiments. In the absence of conflicts, the embodiments can be combined with each other without further elaboration.

[0051] The above descriptions are provided by way of specific examples to illustrate the present invention and are intended solely to facilitate understanding thereof, and are not to be construed as limiting the scope of the invention. Various modifications, alterations, or substitutions may be made based on the inventive concept disclosed herein by those skilled in the art without departing from the scope of the invention.
