The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0038] Please refer to Figures 1 to 5 In one embodiment, an electronic atomization device is provided. The electronic atomization device mainly includes an atomization component 1, a presence sensor 2 and a circuit board 3. Of course, the electronic atomization device also includes an atomization shell 4. The atomization component 1, the presence sensor 2 and the circuit board 3 are installed in the atomization shell 4.

[0039] The atomizer shell 4 can be an integrated structure, or it can be composed of multiple shells. Part of the shell of the atomizer shell 4 can also be a detachable structure, so that the atomizer shell 4 can be opened by removing part of the shell, and the parts inside the atomizer shell 4 can be replaced and maintained, such as maintaining and replacing the atomizer assembly 1, the in-position sensor 2 and the circuit board 3.

[0040] The atomizing shell 4 has a accommodating cavity 41, and a plug-in port 42 is provided on one end side of the atomizing shell 4. The atomizing assembly 1 has an atomizing cavity 10, and the atomizing cavity 10 has a first end and a second end opposite to each other. The first end of the atomizing cavity 10 has an opening, and the opening is used to plug in the atomizing matrix 6. The end surface or axial side of the second end of the atomizing cavity 10 is provided with an air inlet hole, and the air inlet hole is used to introduce air into the atomizing cavity 10. The opening of the atomizing cavity 10 is aligned and communicated with the plug-in port 42 along the axial direction, and the user can plug the atomizing matrix 6 into the atomizing cavity 10 through the plug-in port 42.

[0041] The atomization 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. There are through holes in the first mounting seat 11 and the second mounting seat 13. One end of the heating tube 12 is sealed and fixedly connected to the first mounting seat 11, and the other end of the heating tube 12 is sealed 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 connected in sequence to form an atomization chamber 10, wherein the through hole in the first mounting seat 11 is the first end of the atomization chamber 10, that is, the first mounting seat 11 is close to the plug interface 42, and the first mounting seat 11 has an opening of the atomization chamber 10, and the through hole in the second mounting seat 13 is the second end of the atomization chamber 10, that is, the second mounting seat 13 is far away from the plug interface 42, and the second mounting seat 13 has an air inlet hole of the atomization chamber 10.

[0042] The heating tube 12 may include a metal tube and a heating plate, the heating plate may be attached to the circumferential outer side or the axial inner side of the metal tube, the heating plate may heat the metal tube, and the heating tube 12 is a resistance heating structure. In other embodiments, the heating tube 12 may include a metal tube and an electromagnetic induction coil, the electromagnetic induction coil is located on the circumferential outer side of the metal tube, the electromagnetic induction coil may electromagnetically heat the metal tube, and the heating tube 12 of this structure is an electromagnetic heating structure.

[0043] In this embodiment, the in-position sensor 2 is installed in the accommodating cavity 41 of the atomizing shell 4, and the in-position sensor 2 is located outside the atomizing cavity 41. A through hole is provided on the side wall of the atomizing cavity 41. The in-position sensor 2 detects whether the atomizing matrix 6 is inserted into the atomizing cavity 41 through the through hole.

[0044] In this embodiment, there are two in-position sensors 2, one in-position sensor 2 is arranged at the first end of the atomizing chamber 41, and the other in-position sensor 2 is arranged at the second end of the atomizing chamber 41. The in-position sensor 2 located at the first end of the atomizing chamber 41 can be used to detect whether the atomizing matrix 6 is inserted into the atomizing chamber 41, and to detect whether the atomizing matrix 6 is pulled out of the atomizing chamber 41 as a whole; the in-position sensor 2 located at the second end of the atomizing chamber 41 is used to detect whether the atomizing matrix 6 is inserted into the bottom of the atomizing chamber 41, that is, whether it is plugged in place, and to detect whether the atomizing matrix 6 leaves the bottom of the atomizing chamber 41.

[0045] In this embodiment, the two on-site sensors 2 are similar to two switches installed in series on the control circuit. When the two on-site sensors 2 detect the atomized matrix 6, the control circuit is turned on, triggering the atomization component 1 to start heating the atomized matrix 6; when any one of the on-site sensors 2 does not detect the atomized matrix 6, the circuit is disconnected, triggering the atomization component 1 to turn off heating.

[0046] Providing two in-place sensors 2 can improve the accuracy of preventing false start-up. For example, when the atomizing matrix 6 is inserted, if it is not plugged into place, the in-place sensor 2 located at the second end of the atomizing chamber 41 does not detect the atomizing matrix 6, that is, the in-place sensor 2 will not be triggered, and the heating will not be started or will be turned off, which can avoid the atomizing matrix 6 being mistakenly inserted or starting the heating when it is not inserted, and can further reduce the probability of false start-up.

[0047] In other embodiments, a greater number of on-site sensors 2 may be provided, for example, a plurality of on-site sensors 2 may be correspondingly provided at different axial positions of the atomizing chamber 10 , so as to further reduce the probability of mis-starting.

[0048] In this embodiment, the first mounting seat 11 and the second mounting seat 13 are respectively provided with radial through holes, and the in-position sensor 2 can be a photoelectric sensor, such as a laser sensor. The in-position sensor 2 is located outside the through hole, and docked with the through hole at one end of the in-position sensor 2. A transmitting part and a receiving part are provided at one end of the in-position sensor 2. The transmitting part is used to transmit the detection light, and the receiving part is used to receive the reflected detection light. The circuit board 3 can calculate whether there is an atomizing matrix 6 in the atomizing chamber 10 by the time difference between the emitted light and the received light; when the atomizing matrix 6 is not inserted, the detection light emitted by the in-position sensor 2 passes through the through hole into the atomizing chamber 10, the detection light is reflected by the inner wall of the atomizing chamber 10, and the reflected light passes through the through hole and is collected by the receiving part, and the circuit board 3 can pass the time difference between the emitted light and the received light is relatively large; when the atomizing matrix 6 is inserted, the detection light emitted by the in-position sensor 2 passes through the through hole into the atomizing chamber 10, the detection light is reflected by the atomizing matrix 6 of the atomizing chamber 10, and the reflected light passes through the through hole and is collected by the receiving part, and the circuit board 3 can pass the time difference between the emitted light and the received light is relatively small.

[0049] In this embodiment, the in-position sensor 2 can be directly fixed on the circuit board 3, and the circuit board 3 is arranged parallel to the axial direction of the atomization chamber 10. The two in-position sensors 2 are arranged vertically on the circuit board 3. The direction in which the two in-position sensors 2 emit detection light is perpendicular to the axial direction of the atomization chamber 10, that is, the two in-position sensors 2 emit detection light from the radial direction into the atomization chamber 10.

[0050] In other embodiments, the in-position sensor 2 may also be fixed on a bracket in the accommodating cavity 41 , and the in-position sensor 2 is electrically connected to the circuit board 3 via a cable; with this structural setting, the circuit board 3 has greater installation freedom, and the circuit board 3 can be installed at other positions of the accommodating cavity 41 .

[0051] In this embodiment, the principle steps of the two in-position sensors 2 controlling the start and stop of heating are as follows:

[0052] Please refer to Figure 2 and Figure 3 , the insertion state of the atomizing matrix 6 includes an incomplete insertion state and a complete insertion state. When the atomizing matrix 6 is initially inserted, it is in the incomplete insertion state. At this time, the in-position sensor 2 located at the first end of the atomizing chamber 10 detects that the atomizing matrix 6 is inserted into the opening of the atomizing chamber 10, but the in-position sensor 2 located at the second end of the atomizing chamber 10 does not detect that the atomizing matrix 6 is inserted into the bottom of the atomizing chamber 10, and heating is not started; when the atomizing matrix 6 is continuously inserted to the bottom and is in the complete insertion state, the two in-position sensors 2 detect that the atomizing matrix 6 is inserted into the atomizing chamber 10, and heating is started;

[0053] Please refer to Figure 4 and Figure 5 The atomizing matrix 6 withdrawal state includes an incomplete insertion state and a complete insertion state. The atomizing matrix 6 is in the incomplete withdrawal state when it is initially withdrawn. At this time, the in-position sensor 2 at the first end of the atomizing chamber 10 detects that the atomizing matrix 6 is inserted into the opening of the atomizing chamber 10, and the in-position sensor 2 at the second end of the atomizing chamber 10 does not detect that the atomizing matrix 6 is inserted into the bottom of the atomizing chamber 10, and the heating is turned off. That is, the atomizing matrix 6 does not need to be completely withdrawn, and the heating will be automatically turned off if it is partially withdrawn.

[0054] The electronic atomization device of this embodiment has an on-site sensor 2 on the outside of the atomization chamber 10 for detecting whether an atomization matrix 6 is plugged into the atomization chamber 10. The on-site sensor 2 serves as a trigger switch. When it is detected that the atomization matrix 6 is plugged into the atomization chamber 10, the heating is triggered to start; when it is not detected that the atomization matrix 6 is plugged into the atomization chamber 10, the heating is triggered to shut down. The user can automatically start the heating when inserting the atomization matrix 6 and automatically shut down the heating when pulling out the atomization matrix 6. This can avoid the wrong start of heating caused by physical buttons and can improve the heating efficiency and shut down the heating in time to save energy.

[0055] Please refer to Figure 6 In one embodiment, the electronic atomization device may also be provided with a position sensor 2 , and the position sensor 2 is arranged at the second end of the atomization chamber 10 , that is, the position sensor 2 is located at the bottom position of the atomization chamber 10 .

[0056] When the atomizing matrix 6 is inserted to the bottom of the atomizing chamber 10, the in-position sensor 2 detects the insertion of the atomizing matrix 6 and triggers the start of heating; when the atomizing matrix 6 is pulled out of the bottom of the atomizing chamber 10, the in-position sensor 2 does not detect the insertion of the atomizing matrix 6 and triggers the shutdown of heating.

[0057] A position sensor 2 is correspondingly arranged at the bottom of the atomizing chamber 10, which can also prevent accidental start-up compared with the existing physical buttons.

[0058] Please refer to Figure 1 In one embodiment, a light-transmitting member 14 can be installed in the through holes of the first mounting seat 11 and the second mounting seat 13. The light-transmitting member 14 can be a light-transmitting structure such as a lens and a light guide column. One end of the in-position sensor 2 abuts against the light-transmitting member 14, and the in-position sensor 2 emits and collects detection light through the light-transmitting member 14.

[0059] The provision of the light-transmitting member 14 can play a role in guiding light, can eliminate the gap between the presence sensor 2 and the first mounting seat 11 and the second mounting seat 13, avoid scattering of emitted light and reflected light, and can improve the detection accuracy of the presence sensor 2.

[0060] In one embodiment, one end of the two in-position sensors 2 having a transmitting part and a receiving part respectively abuts against the outer side surfaces of the first mounting seat 11 and the second mounting seat 13; or the outer side surfaces of the first mounting seat 11 and the second mounting seat 13 are respectively provided with grooves, which are connected to the through holes, and one end of the two in-position sensors 2 having a transmitting part and a receiving part are respectively inserted into the grooves of the first mounting seat 11 and the second mounting seat 13; or, one end of the two in-position sensors 2 having a transmitting part and a receiving part are respectively inserted into the through holes of the first mounting seat 11 and the second mounting seat 13.

[0061] Such an arrangement can also eliminate the gap between the in-position sensor 2 and the first mounting seat 11 or the second mounting seat 13 , thereby improving the detection accuracy of the in-position sensor 2 .

[0062] In one embodiment, the in-position sensor 2 can also be a contact sensor, and the trigger ends of the two in-position sensors 2 are respectively inserted into the first mounting seat 11 and the second mounting seat 13, and parts of the trigger ends of the two in-position sensors 2 are located in the atomization chamber 10. When the atomization chamber 10 is inserted into the atomization matrix 6, the atomization matrix 6 will contact the trigger end of the in-position sensor 2, thereby triggering the in-position sensor 2.

[0063] In one embodiment, the plurality of in-position sensors 2 can be different types of sensors, for example, one is a photoelectric sensor and the other is a contact sensor. By using different types of sensors, when one sensor fails, the other sensor can ensure the detection accuracy.

[0064] Please refer to Figure 1 In one embodiment, the atomizer assembly 1 may further include an outer cylinder 15, the inner diameter of the outer cylinder 15 is larger than the outer diameter of the heating tube 12, the outer cylinder 15 is spaced apart on the circumferential outer side of the heating tube 12, one end of the outer cylinder 15 extends to be sealed and connected to the first mounting seat 11, and the other end of the outer cylinder 15 extends to be sealed and connected to the second mounting seat 13.

[0065] A sealed heat-insulating cavity can be formed between the outer cylinder 15 and the heating tube 12, which can prevent the heat energy generated by the heating tube 12 from diffusing, improve the heating and baking efficiency of the heating tube 12, and save electric energy.

[0066] The outer cylinder 15 may be an integrated structure with one or both of the first mounting seat 11 and the second mounting seat 13. For example, the outer cylinder 15 and the first mounting seat 11 are an integrated structure, and the outer cylinder 15 and the second mounting seat 13 are sealed by interference fit or a seal.

[0067] Please refer to Figure 7 In one embodiment, the electronic atomization device further includes a battery 5, which is installed in the accommodating cavity 41 of the atomization shell 4, and the battery 5 is electrically connected to the circuit board 3, and the battery 5 provides electrical energy for the circuit board 3, the atomization assembly 1 and the in-position sensor 2.

[0068] The circuit board 3 may also be connected to a charging socket, which may be disposed on the side or bottom of the atomizing shell 4 , and the charging socket may charge the battery 5 .

[0069] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
