[0018] The present invention will be described in more detail below with reference to the drawings. Among them, similar reference numerals are used for similar parts in different embodiments. In the following description, many details are described for ease of understanding. However, those skilled in the art should easily understand that some features may be omitted depending on the situation, or may be replaceable with other parts, materials, or methods.

[0019] Furthermore, the features, operations, or characteristics described in the specification can be combined in an appropriate manner to form various embodiments. Also, each step or operation in the method description can be changed or adjusted in order in a manner that is clearly recognizable to those skilled in the art. Therefore, the order in the specification and drawings is for clearly explaining specific embodiments and does not indicate an order that must be followed unless there is a specific order to be followed.

[0020] The numbers attached to the parts in this specification (such as "first", "second", etc.) are for distinguishing the objects to be described and do not have an order or technical meaning. Also, "connection" or "coupling" in the present application includes direct and indirect connections (couplings) unless otherwise specified.

[0021] Referring to FIGS. 1 to 5, in one embodiment, an electronic atomization device is provided. This electronic atomization device mainly includes an atomization component 1, a set detection sensor 2, and a circuit board 3. Of course, this electronic atomization device further includes an atomization housing 4, and the atomization component 1, the set detection sensor 2, and the circuit board 3 are mounted in the atomization housing 4.

[0022] The atomization housing 4 may have an integrated structure, or the atomization housing 4 may be formed by combining a plurality of housings. A part of the housing of the atomization housing 4 may have a detachable structure. By removing a part of the housing, the atomization housing 4 can be opened, and the components inside the atomization housing 4 can be maintained and replaced. For example, the atomization component 1, the set detection sensor 2, and the circuit board 3 can be maintained and replaced.

[0023] The atomization housing 4 has a receiving cavity 41, and an insertion port 42 is provided on the side surface of one end of the atomization housing 4. The atomization component 1 has an atomization cavity 10. The atomization cavity 10 has a first end and a second end facing each other. The first end of the atomization cavity 10 has an opening, which is used for inserting the atomization substrate 6. An air intake hole is provided on the end face or the axial side surface of the second end of the atomization cavity 10, and this air intake hole is used for introducing air into the atomization cavity 10. The opening of the atomization cavity 10 and the insertion port 42 are aligned and communicated in the axial direction, and the user can insert the atomization substrate 6 into the atomization cavity 10 through the insertion port 42.

[0024] The atomization component 1 mainly includes a first mounting seat 11, a heating tube 12, and a second mounting seat 13. Both the first mounting seat 11 and the second mounting seat 13 have a cylindrical structure and have through holes inside. One end of the heating tube 12 is sealed and fixedly connected at the first mounting seat 11, and the other end of the heating tube 12 is sealed and fixedly connected at the second mounting seat 13. The first mounting seat 11, the heating tube 12, and the second mounting seat 13 are sequentially communicated to form the atomization cavity 10. Here, the through hole in the first mounting seat 11 is the first end of the atomization cavity 10, that is, the first mounting seat 11 is located near the insertion port 42, and the first mounting seat 11 has the opening of the atomization cavity 10. The through hole in the second mounting seat 13 is the second end of the atomization cavity 10, that is, the second mounting seat 13 is located away from the insertion port 42, and the second mounting seat 13 has the air intake hole of the atomization cavity 10.

[0025] The heating tube 12 may include a metal tube and a heating sheet. The heating sheet may be attached to the outer circumferential surface or the inner axial surface of the metal tube. The heating sheet can heat the metal tube, and this heating tube 12 has 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 outside the circumferential direction of the metal tube, and the electromagnetic induction coil can electromagnetic-heat the metal tube, and the heating tube 12 with this structure is an electromagnetic heating structure.

[0026] In this embodiment, the set detection sensor 2 is installed in the accommodation cavity 41 of the atomization housing 4 and is located outside the atomization cavity 10. Through holes are provided on the side wall of the atomization cavity 10, and the set detection sensor 2 detects whether the atomization substrate 6 is inserted into the atomization cavity 10 through the through holes.

[0027] In this embodiment, there are two set detection sensors 2. One set detection sensor 2 is installed at the first end of the atomization cavity 10, and the other set detection sensor 2 is installed at the second end of the atomization cavity 10. The set detection sensor 2 located at the first end of the atomization cavity 10 is used to detect whether the atomization substrate 6 is inserted into the atomization cavity 10 and to detect whether the entire atomization substrate 6 has been removed from the atomization cavity 10. The set detection sensor 2 located at the second end of the atomization cavity 10 is used to detect whether the atomization substrate 6 is inserted into the bottom of the atomization cavity 10, that is, whether it is fully inserted, and to detect whether the atomization substrate 6 has left the bottom of the atomization cavity 10.

[0028] In this embodiment, the two set detection sensors 2 correspond to two switches connected in series to the control circuit. When both of the two set detection sensors 2 detect the atomization substrate 6, the control circuit is turned on, and the atomization component 1 is triggered to start heating the atomization substrate 6. When any one of the set detection sensors 2 does not detect the atomization substrate 6, the circuit is turned off, and the atomization component 1 is triggered to stop heating.

[0029] By installing two set detection sensors 2, the accuracy of preventing misoperation can be improved. For example, when the atomization substrate 6 is inserted, if it is not fully inserted, the set detection sensor 2 located at the second end of the atomization cavity 10 does not detect the atomization substrate 6, so this set detection sensor 2 is not triggered, and at that time, the start or stop of heating is not allowed. Thereby, it is possible to prevent the start of heating in the state where the atomization substrate 6 is misinserted or not inserted, and the probability of misoperation can be further reduced.

[0030] In other embodiments, more set detection sensors 2 may be provided. For example, by installing a plurality of set detection sensors 2 at different positions in the axial direction of the atomization cavity 10, the probability of misoperation can be further reduced.

[0031] In this embodiment, the first mounting seat 11 and the second mounting seat 13 are respectively provided with radial through holes, and the set detection sensor 2 may be a photoelectric sensor, for example, a laser sensor. The set detection sensor 2 is located outside the through hole, one end of the set detection sensor 2 is connected to the through hole, and both a light emitting part and a light receiving part are installed at one end of the set detection sensor 2. The light emitting part is used to emit detection light, and the light receiving part is used to receive the reflected detection light. The circuit board 3 can calculate whether there is an atomization substrate 6 in the atomization cavity 10 based on the time difference between the emission of light and the reception of light. When the atomization substrate 6 is not inserted, the detection light emitted from the set detection sensor 2 passes through the through hole and enters the atomization cavity 10. The detection light is reflected by the inner wall of the atomization cavity 10, and the reflected light passes through the through hole and is received by the light receiving part, and the time difference between the emission of light and the reception of light is relatively large. When the atomization substrate 6 is inserted, the detection light emitted from the set detection sensor 2 passes through the through hole and enters the atomization cavity 10. The detection light is reflected by the atomization substrate 6 in the atomization cavity 10, and the reflected light passes through the through hole and is received by the light receiving part, and the time difference between the emission of light and the reception of light is relatively small.

[0032] In this embodiment, the set detection sensor 2 may be directly fixed on the circuit board 3. The circuit board 3 is installed parallel to the axial direction of the atomization cavity 10. The two set detection sensors 2 are vertically installed on the circuit board 3. The direction in which the two set detection sensors 2 emit the detection light is perpendicular to the axial direction of the atomization cavity 10, that is, the detection light emitted from the radial direction of the two set detection sensors 2 enters the atomization cavity 10.

[0033] In other embodiments, the set detection sensor 2 may be fixed to a bracket within the accommodation cavity 41. The set detection sensor 2 is electrically connected to the circuit board 3 via a cable. With the installation of this structure, the circuit board 3 has a greater degree of mounting freedom and can be mounted at other positions within the accommodation cavity 41.

[0034] In this embodiment, the steps of the principle of starting and stopping heating by the two set detection sensors 2 are as follows.

[0035] Referring to FIGS. 2 and 3, the insertion state of the atomization substrate 6 includes a fully inserted state and an incompletely inserted state. When the atomization substrate is initially inserted, it is in the incompletely inserted state. In this case, the set detection sensor 2 located at the first end of the atomization cavity 10 detects that the atomization substrate 6 has been inserted into the opening of the atomization cavity 10, but the set detection sensor 2 located at the second end of the atomization cavity 10 does not detect that the atomization substrate 6 has been inserted into the bottom of the atomization cavity 10, and heating is not started. When the atomization substrate 6 continues to be inserted to the bottom and is in the fully inserted state, when the two set detection sensors 2 detect that the atomization substrate 6 has been inserted into the atomization cavity 10, heating is started.

[0036] Referring to FIGS. 4 and 5, the extraction state of the atomization substrate 6 includes a complete extraction state and an incomplete extraction state. When the atomization substrate 6 is initially extracted, it is in an incomplete extraction state. In that case, the set detection sensor 2 located at the first end of the atomization cavity 10 detects that the atomization substrate 6 is inserted into the opening of the atomization cavity 10, and the set detection sensor 2 located at the second end of the atomization cavity 10 does not detect that the atomization substrate 6 is inserted into the bottom of the atomization cavity 10, and the heating is stopped. That is, the atomization substrate 6 does not need to be completely extracted, and when a part of it is extracted, the heating is automatically stopped.

[0037] According to the electronic atomization device of this embodiment, since a set detection sensor 2 capable of detecting whether the atomization substrate 6 is inserted into the atomization cavity 10 is installed outside the atomization cavity 10, the set detection sensor 2 serves as a trigger switch. When it detects that the atomization substrate 6 is inserted into the atomization cavity 10, it triggers the start of heating. When it does not detect that the atomization substrate 6 is inserted into the atomization cavity 10, it triggers the stop of heating. Thereby, when the user inserts the atomization substrate 6, the heating is automatically started. When the atomization substrate 6 is removed, the heating is automatically stopped. As a result, it is possible to prevent heating due to accidental starting by a physical button, improve the heating efficiency, and timely stop the heating to save power.

[0038] Referring to FIG. 6, in one embodiment, one set detection sensor 2 may be installed in the electronic atomization device. This one set detection sensor 2 is installed at the second end of the atomization cavity 10, that is, the set detection sensor 2 is installed at the bottom position of the atomization cavity 10.

[0039] When the atomization substrate 6 is inserted to the bottom of the atomization cavity 10, the set detection sensor 2 detects the insertion of the atomization substrate 6 and triggers the start of heating. When the atomization substrate 6 is removed and separated from the bottom of the atomization cavity 10, the set detection sensor 2 does not detect the insertion of the atomization substrate 6 and triggers the stop of heating.

[0040] By installing one set of detection sensors 2 corresponding to the bottom position of the atomization cavity 10, it can also play a role in preventing accidental startup compared with the conventional physical buttons.

[0041] Referring to FIG. 1, in one embodiment, a light-transmitting component 14 may be installed in the through holes of the first mounting seat 11 and the second mounting seat 13. The light-transmitting component 14 may be a light-transmitting structure such as a lens or a light guide column. One end of the set detection sensor 2 is in contact with the light-transmitting component 14. The set detection sensor 2 emits detection light through the light-transmitting component 14 and receives the detection light.

[0042] The installation of the light-transmitting component 14 plays a role in light guiding, eliminates the gaps between the set detection sensor 2 and the first mounting seat 11, and between the set detection sensor 2 and the second mounting seat 13, prevents the scattering of the emitted light and the reflected light, and can improve the detection accuracy of the set detection sensor 2.

[0043] In one embodiment, one end of the two set detection sensors 2 having a light-emitting part and a light-receiving part is respectively in contact with the outer surfaces of the first mounting seat 11 and the second mounting seat 13. Or, grooves are respectively provided on the outer surfaces of the first mounting seat 11 and the second mounting seat 13. These grooves communicate with the through holes. One end of the two set detection sensors 2 having a light-emitting part and a light-receiving part is respectively fitted into the grooves of the first mounting seat 11 and the second mounting seat 13. Or, one end of the two set detection sensors 2 having a light-emitting part and a light-receiving part is respectively inserted into the through holes of the first mounting seat 11 and the second mounting seat 13.

[0044] Such installation can also eliminate the gap between the set detection sensor 2 and the first mounting seat 11 or the gap between the set detection sensor 2 and the second mounting seat 13, and can improve the detection accuracy of the set detection sensor 2.

[0045] In one embodiment, the set detection sensor 2 may be a contact sensor. The trigger ends of the two set detection sensors 2 are respectively inserted into the first mounting seat 11 and the second mounting seat 13, and a part of the trigger ends of the two set detection sensors 2 is located in the atomization cavity 10. When the atomization substrate 6 is inserted into the atomization cavity 10, the atomization substrate 6 contacts the trigger end of the set detection sensor 2 to trigger the set detection sensor 2.

[0046] In one embodiment, the plurality of set detection sensors 2 may be different types of sensors. For example, one set detection sensor 2 is a photoelectric sensor, and the other set detection sensor 2 is a contact sensor. By using different types of sensors in combination, even if one sensor fails, the other sensor can ensure the detection accuracy.

[0047] Referring to FIG. 1, in one embodiment, the atomization component 1 further includes 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 covered at an interval on the circumferential outer side of the heating tube 12. One end of the outer cylinder 15 extends and is sealingly connected to the first mounting seat 11, and the other end of the outer cylinder 15 extends and is sealingly connected to the second mounting seat 13.

[0048] The outer cylinder 15 and the heating tube 12 form a sealed heat insulation cavity, thereby preventing the release of heat generated from the heating tube 12, improving the baking efficiency of the heating tube 12, and saving electricity.

[0049] The outer cylinder 15 may be of 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 is of an integrated structure with the first mounting seat 11, and the outer cylinder 15 realizes a sealed connection with the second mounting seat 13 by an interference fit method or a sealing component.

[0050] Referring to FIG. 7, in one embodiment, this electronic atomization device further includes a battery 5. The battery 5 is mounted within the accommodation cavity 41 of the atomization housing 4 and is electrically connected to the circuit board 3 to supply power to the circuit board 3, the atomization component 1, and the set detection sensor 2.

[0051] A charging port may be further connected to the circuit board 3. The charging port may be installed on the side surface or the bottom surface of the atomization housing 4. The charging port can achieve charging of the battery 5.

[0052] The present invention has been described above using specific examples, which are for helping to understand the present invention and do not limit the present invention. Those skilled in the technical field of the present invention can make some simple inferences, deformations, or substitutions based on the idea of the present invention.
