For those of ordinary skill in the art, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0033] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the drawings.

[0034] Referring to Figure 1a - Figure 1b as shown, an embodiment of the present invention provides a multi-airway passage, including: a nozzle 1; an atomizing air passage 2 connected to the nozzle 1 for communicating the nozzle 1 and an atomizer (not shown in the figure) in a first state ( Figure 1b the state shown); a negative pressure sensing air passage 3 connected to the nozzle 1; an air passage control mechanism 4 that controls the nozzle 1 to communicate with the atomizing air passage 2 and disconnects from the negative pressure sensing air passage 3 in the first state, and controls the nozzle 1 to disconnect from the atomizing air passage 2 and communicate with the negative pressure sensing air passage 3 in a second state ( Figure 1a the state shown).

[0035] In this embodiment, the multi-airway passage includes an atomizing air passage 2 and a negative pressure sensing air passage 3, both of which are connected to the nozzle 1, and the air passage control mechanism 4 controls the flow direction of the air passage. The first state in this embodiment, that is, the use state, refers to the user sucking through the nozzle 1. When a sucking action occurs, during the continuous process of the sucking action, and when a sucking action has occurred within a set time, it is all in the first state. The second state in this embodiment, that is, the non-use state, refers to the situation where the user has not started sucking, or no sucking action has occurred within the set time, that is, the sucking has ended, and it is all in the second state.

[0036] In one embodiment, in the initial state, that is, the second state, referring to Figure 1aAs shown, the gas path control mechanism 4 closes the atomizing gas path 2 and opens the negative pressure induction gas path 3. When suction occurs, it switches from the second state to the first state. In the first state, refer to Figure 1b As shown, the gas path control mechanism 4 controls the nozzle 1 to communicate with the atomizing gas path 2 and disconnects from the negative pressure induction gas path 3. At this time, the atomizing gas path 2 can connect the nozzle 1 and the atomizer, facilitating the aerosol generated by atomization to enter the mouth through the nozzle 1 and preventing it from entering the negative pressure induction gas path 3. When the suction ends, it switches from the first state to the second state. In the second state, the gas path control mechanism 4 controls the nozzle 1 to disconnect from the atomizing gas path 2, and there is no connection between the nozzle 1 and the atomizer. Therefore, the liquid cannot enter the nozzle 1 through the atomizing gas path 2, effectively preventing liquid leakage. And in the second state, the nozzle 1 is connected to the negative pressure induction gas path 3, facilitating the induction of the next suction. The gas path control mechanism 4 can be multiple, respectively controlling the connection states between the two gas paths and the nozzle 1, or it can be single, switching and controlling the connection states between the two gas paths and the nozzle 1. This embodiment does not limit this.

[0037] In the multi-gas path channel disclosed in this embodiment, by adding an independent negative pressure induction gas path 3 outside the atomizing gas path 2 and controlling the gas path connection state through the gas path control mechanism 4, it can be ensured that the atomizer and the nozzle 1 are not connected in the non-use state, achieving the prevention of liquid leakage.

[0038] Refer to Figure 2a - Figure 2b As shown, another embodiment of the present invention provides a multi-gas path channel. The gas path control mechanism 4 includes a solenoid valve 41 or a rotating mechanism (not shown in the figure). In one embodiment, the gas path control mechanism 4 includes a solenoid valve 41, and corresponding solenoid valves 41 are provided in both the atomizing gas path 2 and the negative pressure induction gas path 3. In the initial state, that is, in the second state, refer to Figure 2a As shown, the solenoid valve 41 in the atomizing gas path 2 closes the atomizing gas path 2, disconnecting the atomizer (not shown in the figure) from the nozzle 1, and the solenoid valve 41 in the negative pressure induction gas path 3 opens the negative pressure induction gas path 3, forming a through path between the negative pressure induction gas path 3 and the nozzle 1. When starting to suction, the negative pressure induction gas path 3 senses the existence of negative pressure, that is, it switches from the second state to the first state. In the first state, refer to Figure 2bAs shown in the figure, the solenoid valve 41 in the atomization gas path 2 opens the atomization gas path 2, and the solenoid valve 41 in the negative pressure induction gas path 3 closes the negative pressure induction gas path 3. The atomization gas path 2 is communicated with the mouthpiece 1, and the aerosol generated by the atomizer can enter the user's mouth through the mouthpiece 1. The solenoid valve 41 in the atomization gas path 2 is set to remain open if negative pressure can be continuously sensed within time T. Correspondingly, the solenoid valve 41 in the negative pressure induction gas path 3 remains closed. When the suction is completed and the negative pressure is not sensed in the atomization gas path 2 within the set time T, it switches from the first state to the second state. The solenoid valve 41 of the atomization gas path 2 closes the atomization gas path 2, and the solenoid valve 41 of the negative pressure induction gas path 3 opens the negative pressure induction gas path 3, that is, it returns to the initial state. In another embodiment, the gas path control mechanism 4 includes a rotating mechanism, and the rotating mechanism is used to realize the switching and maintaining of the two gas path states. Using the solenoid valve 41 or the rotating mechanism can simply and quickly realize the switching and maintaining of the gas path states.

[0039] Referring to Figure 3a - Figure 4c As shown in the figure, an embodiment of the present invention provides an electronic cigarette, including the multi-gas path channels in any one of the foregoing embodiments, and further including: an atomizer 5. For an electronic cigarette, problems such as e-liquid leakage and contamination of the mouthpiece caused by a single gas path channel greatly affect the user's sensory experience and physical health. The electronic cigarette in this embodiment includes multi-gas path channels, which can give full play to the advantages of the multi-gas path channels, effectively prevent oil leakage, and greatly improve the user's sensory experience and the reliability of the electronic cigarette.

[0040] Referring to Figure 3a - Figure 4c As shown in the figure, another embodiment of the present invention provides an electronic cigarette, further including: a housing 6. Both the atomization gas path 2 and the negative pressure induction gas path 3 extend along the axial direction ( Figure 3a - Figure 4c shown as the X direction) of the housing 6 and are arranged inside the housing 6. The housing 6 is provided with a first air inlet hole 61 communicated with the atomization gas path 2 and a second air inlet hole 62 communicated with the negative pressure induction gas path 3; a first air pressure sensor 71 and a second air pressure sensor 72. The first air pressure sensor 71 is arranged in the atomization gas path 2, and the second air pressure sensor 72 is arranged in the negative pressure induction gas path 3. Both the first air pressure sensor 71 and the second air pressure sensor 72 are electrically connected to the gas path control mechanism 4.

[0041] In this embodiment, both the atomization gas path 2 and the negative pressure induction gas path 3 extend along the axial direction of the housing 6 and are arranged inside the housing 6. That is to say, for an electronic cigarette with the atomization gas path 2 arranged axially, only a negative pressure induction gas path 3 parallel to the atomization gas path 2 needs to be added, with low transformation cost and easy manufacturing. Arranging along the axial direction can avoid the radial direction of the electronic cigarette ( Figure 3a - Figure 4cThe length in the Y direction (as shown) is too large for easy use. The first air inlet hole 61 and the second air inlet hole 62 are respectively connected to the atomization air path 2 and the negative pressure induction air path 3, facilitating the formation of negative pressure in the corresponding air paths during state switching or maintenance. The first air pressure sensor 71 and the second air pressure sensor 72 are respectively used to detect the air pressure states of the corresponding air paths, and the air path control mechanism 4 is used to open or close the corresponding air paths according to the detections of the first air pressure sensor 71 and the second air pressure sensor 72. By separately providing independent air inlet holes and air pressure sensors for the two air paths, the reliability of detection can be improved. The air path control mechanism 4 is electrically connected to the first air pressure sensor 71 and the second air pressure sensor 72. For example, electrical signals can be directly transmitted through wires. The electronic cigarette disclosed in this embodiment realizes the rapid switching of the opening and closing functions of the dual air paths through simple automatic induction. During use and storage, users can achieve anti-oil leakage without additional operation steps, with a foolproof operation, no need for adaptation training, and being simple, fast, and practical.

[0042] Referring to Figure 3a - Figure 3c As shown, another embodiment of the present invention provides an electronic cigarette. The air path control mechanism 4 includes a single-hole rotating disk 42 and a driving mechanism 43. The driving mechanism 43 is used to control the through hole 421 on the single-hole rotating disk 42 to align with the first opening 21 of the atomization air path 2 in the first state, so as to connect the nozzle 1 with the atomization air path 2. The driving mechanism 43 is also used to control the through hole 421 to align with the second opening 31 of the negative pressure induction air path 3 in the second state, so as to connect the nozzle 1 with the negative pressure induction air path 3.

[0043] In this embodiment, the air path control mechanism 4 adopts a rotating mechanism, including a single-hole rotating disk 42 and a driving mechanism 43. The driving mechanism 43 can be a motor or the like. The driving mechanism 43 can drive the single-hole rotating disk 42 to rotate. A single through hole 421 is provided on the single-hole rotating disk 42. The position and size of the through hole 421 correspond to the first opening 21 and the second opening 31, as long as the air path is unobstructed when aligned. In one embodiment, the circular single-hole rotating disk 42 extends along the radial direction of the housing 6 ( Figure 3a - Figure 3c the Y direction as shown) and is arranged above the atomization air path 2 and the negative pressure induction air path 3. The axis of the driving mechanism 43 is arranged at the center of the single-hole rotating disk 42. The distances from the centers of the first opening 21, the second opening 31, and the through hole 421 along the radial direction of the housing to the center of the single-hole rotating disk 42 are equal. Referring to Figure 3a As shown, in the initial state, that is, in the second state, the through hole 421 is located above the second opening 31, and the nozzle 1 is connected to the negative pressure induction air path 3, and the air flow direction is as shown by the short arrow in Figure 3a . When suction occurs, air enters from the second air inlet hole 62. The second air pressure sensor 72 detects the negative pressure state in the negative pressure induction air path 3 and outputs a signal to the air path control mechanism 4. The driving mechanism 43 drives the single-hole rotating disk 42 to rotate along the circumferential direction of the electronic cigarette (Figure 3c The Z direction shown in the figure) is rotated by a corresponding angle, that is, from Figure 3a The second state shown switches to Figure 3b In the first state shown, the through hole 421 is aligned with the first opening 21, that is, the negative pressure sensing air path 3 is closed, the suction nozzle 1 is connected with the atomizing air path 2, and the aerosol generated by the atomizer 5 enters the mouth through the atomizing air path 2 and the suction nozzle 1. The air flow direction is as shown in FIG. Figure 3a As shown by the short arrow in the figure. The first air pressure sensor 71 in the atomizing gas circuit 2 is set to be able to continuously sense the existence of negative pressure within T time, then the single-hole rotating disk 42 remains unchanged and the gas circuit state does not change. In other words, when the first air pressure sensor 71 in the atomizing gas circuit 2 does not sense negative pressure within T time, it switches from the first state to the second state, and the first air pressure sensor 71 outputs an electrical signal to the driving mechanism 43, driving the single-hole rotating disk 42 to rotate a corresponding angle, aligning the through hole 421 with the second opening 31 of the negative pressure sensing gas circuit 3, and the negative pressure sensing gas circuit 3 is connected with the suction nozzle 1, returning to the initial state.

[0044] Preferably, considering that the frequency and time interval of conventional puffing actions are usually 30-60 seconds, the time T is set to 2-3 minutes, which can meet the usage habits of most users and reduce false detection.

[0045] Optionally, the atomizer 5 can be arranged in the axial direction ( Figure 3a The atomizer 5 can absorb the smoke liquid from the smoke liquid cavity 7 around the atomization gas path 2 through the liquid absorption structure or liquid absorption material for atomization. Compared with separately setting up electromagnetic valves to control the two gas paths, the structure of using the driving mechanism 43 to drive the single-hole rotating disk 42 is simpler, saves space, and can more reliably ensure that the two gas paths are in opposite states, that is, one is open and the other is closed.

[0046] Reference Figure 3a - Figure 3bAs shown in the figure, another embodiment of the present invention provides an electronic cigarette, further comprising: a liquid chamber 7, a sealing silica gel 8 is provided between the liquid chamber 7 and the single-hole rotating disk 42, and the sealing silica gel 8 is respectively provided with a third opening 81 and a fourth opening 82 corresponding to the first opening 21 and the second opening 31. In one embodiment, the single-hole rotating disk 42, the sealing silica gel 8 and the liquid chamber 7 are sequentially arranged along the axial direction of the housing 6. In order to facilitate the flow of the gas path, the sealing silica gel 8 is respectively provided with a third opening 81 and a fourth opening 82 corresponding to the positions of the first opening 21 and the second opening 31. During use, the rigid single-hole rotating disk 42 is tightly pressed above the elastic sealing silica gel 8 and can rotate freely driven by the driving mechanism 43. By providing the sealing silica gel 8, the sealing performance of the liquid chamber 7 can be improved, further preventing oil leakage, and at the same time, cooperating with the rigid single-hole rotating disk 42, the stability and reliability of the structure can be improved. Preferably, the driving mechanism 43 is fixed above the single-hole rotating disk 42 inside the housing 6.

[0047] Referring to Figure 4a - Figure 4c As shown in the figure, another embodiment of the present invention provides an electronic cigarette, and the gas path control mechanism 4 is a rotating mechanism, comprising a rotating hollow shaft 44 and a driving mechanism 43. One end of the rotating hollow shaft 44 close to the mouthpiece 1 is provided with a first communication port 441, and a second communication port 442 is provided on the side wall of the rotating hollow shaft 44. The side walls of the atomization gas path 2 and the negative pressure induction gas path 3 are respectively provided with a fifth opening 22 and a sixth opening 32 corresponding to the second communication port 442. In this embodiment, the driving mechanism 43 can drive the rotating hollow shaft 44 to rotate along the circumferential direction of the housing 6 ( Figure 4c the Z direction shown in the figure), and the fifth opening 22 and the sixth opening 32 correspond to the second communication port 442, that is, they are at the same height. Referring to Figure 4b As shown in the figure, in the first state, the second communication port 442 is aligned with the fifth opening 22, and the aerosol generated by the atomizer 5 enters the rotating hollow shaft 44 through the atomization gas path 2 and enters the mouthpiece 1 through the first communication port 441, and the air flow direction is as Figure 4b shown by the short arrow in the figure. Referring to Figure 4a As shown in the figure, in the initial state, that is, the second state, the second communication port 442 is aligned with the sixth opening 32, and the air flow direction is as Figure 4a shown by the short arrow in the figure. The structure of using the driving mechanism 43 to drive the rotating hollow shaft 44 is simpler and more space-saving compared with respectively arranging solenoid valves to control the two gas paths, and can more reliably ensure that the two gas paths are in opposite states, that is, one is open and the other is closed. Preferably, the driving mechanism 43 is fixed above the rotating hollow shaft 44 inside the housing 6.

[0048] Referring to Figure 4a - Figure 4bAs shown in the figure, another embodiment of the present invention provides an electronic cigarette. The rotating hollow shaft 44 is arranged in the pipe 9 between the atomization gas path 2 and the negative pressure induction gas path 3. A sealing silica gel 8 is arranged between the rotating hollow shaft 44 and the side wall of the pipe 9. The sealing silica gel 8 is provided with a seventh opening 83 and an eighth opening 84 corresponding to the fifth opening 22 and the sixth opening 32. That is to say, in this embodiment, the rotating hollow shaft 44 is embedded in the hollow cavity of the sealing silica gel 8. The rigid rotating hollow shaft 44 and the elastic sealing silica gel 8 cooperate to improve the sealing performance. Especially for an electronic cigarette with the liquid storage cavity 7 arranged below the rotating hollow shaft 44, it can further prevent oil leakage. At the same time, it can also improve the stability and reliability of the structure. In order to ensure the gas path circulation and good sealing performance, the sealing silica gel 8 is provided with corresponding seventh opening 83 and eighth opening 84 at the positions corresponding to the fifth opening 22 and the sixth opening 32. Preferably, the pipe 9 is a circular pipe and the rotating hollow shaft 44 is cylindrical, which is convenient for rotation.

[0049] Another embodiment of the present invention provides an electronic cigarette. The driving mechanism 43 is a micro motor. The rotation speed of the micro motor is 1000 rpm - 1400 rpm. Using a micro motor as the driving mechanism 43 has low cost and small volume. It can cooperate well with both the single-hole rotating disk 42 and the rotating hollow shaft 44. Setting the rotation speed of the micro motor within 1000 rpm - 1400 rpm can not only ensure reliability but also quickly complete the switching between the states of the two gas paths without obvious blockage feeling during the suction process, providing a better sensory experience. Taking a micro motor with a rotation speed of 1200 rpm driving the single-hole rotating disk 42 as an example, when the first opening 21 of the atomization gas path 2 and the second opening 31 of the negative pressure induction gas path 3 are arranged on both sides of the rotating disk in a straight line, that is, when the angle between the first opening 21, the center of the single-hole rotating disk 42 and the second opening 31 is 180°, the through hole 421 of the single-hole rotating disk 42 rotates from being aligned with the first opening 21 to being aligned with the second opening 31, and the required time is less than 0.003 seconds, enabling a quick response when the user sucks without obvious blockage feeling.

[0050] Refer to Figure 3a - Figure 4cAs shown in the figure, another embodiment of the present invention provides an electronic cigarette. The first air pressure sensor 71 is disposed at one end of the atomizing gas path 2 away from the mouthpiece 1 and is opposite to the first air inlet hole 61. The second air pressure sensor 72 is disposed at one end of the negative pressure induction gas path 3 away from the mouthpiece 1 and is opposite to the second air inlet hole 62. That is to say, in this embodiment, both the first air pressure sensor 71 and the second air pressure sensor 72 are disposed at positions away from the mouthpiece 1, which is convenient for the overall structure design of the electronic cigarette and the fixation of the air pressure sensor. And during use, after air enters the atomizing gas path 2 from the first air inlet hole 61, it can fully mix with the aerosol generated by atomization in the entire atomizing gas path 2, resulting in a better taste. The air pressure sensor is disposed opposite to the air inlet, which can improve the sensitivity and accuracy of the air pressure sensor detection. Refer to Figure 3a - Figure 3c As shown in the figure, in one embodiment, both the first air pressure sensor 71 and the second air pressure sensor 72 are disposed at the bottom of the gas path, and the first air inlet hole 61 and the second air inlet hole 62 are respectively disposed on the electronic cigarette housing 6 at positions parallel to the height of the air pressure sensor.
