While the invention will be described in conjunction with the preferred embodiments, it is not intended that features of the invention be limited to these embodiments. On the contrary, the invention is described in connection with the embodiments for the purpose of covering alternatives or modifications that may be extended based on the claims of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention may be practiced without these particulars. Moreover, some of the specific details have been left out of the description in order to avoid obscuring or obscuring the focus of the present invention. It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1 to 4, the present invention provides an aerosol-generating device 1, the aerosol-generating device 1 comprising a housing 11, the housing 11 having a first internal cavity 11 a; a cigarette holder 10 having a second inner cavity 10a and a mouthpiece 13, wherein the cigarette holder 10 is movably disposed at one end of the first inner cavity 11a, the other end of the cigarette holder 10 in the extending direction (shown in the direction X in fig. 1 and 2) is used for connecting with a cigarette rod, and the first inner cavity 11a is communicated with the second inner cavity 10a and at least forms an aerosol channel; the atomizing part 30 is arranged in the first inner cavity 11a, the atomizing part 30 is provided with an atomizing cavity 31, a heating body 32 is arranged in the atomizing cavity 31, and the aerosol generated by heating the cigarette liquid by the heating body 32 flows to the product suction opening 13 from the aerosol channel for the user to suck; a first opening 21 is provided in the housing 11 or the mouthpiece 10. Preferably, the first opening 21 is provided on the mouthpiece 10.
Referring to fig. 1, 3 and 4, the cigarette holder 10 and the housing 11 can move relatively to open the first opening 21, the first opening 21 is communicated with the outside, no smoke flows into the atomizing cavity 31, when a user sucks through the mouthpiece 13, outside air can flow into the aerosol channel through the first opening 21 and then flows out from the mouthpiece 13, a first airflow path (shown in C in fig. 3 and 4) is formed, the air pressure sensor cannot be triggered, and the heater 32 is prevented from being started to cause dry burning.
In addition, referring to fig. 2, 5 and 6, the cigarette holder 10 and the housing 11 can move relatively to close the first opening 21, the first opening 21 is not communicated with the outside, the smoke liquid flows into the atomizing cavity 31, when a user sucks through the product suction opening 13, outside air can flow into the aerosol channel through the atomizing cavity 31 and then flows out from the product suction opening 13, a second air flow path (shown in D in fig. 5 and 6) is formed, the air pressure sensor is triggered, the trigger circuit is switched on, and the heating element 32 heats the smoke liquid to generate aerosol for the user to suck. The external air does not flow into the aerosol passage through the first opening 21.
Therefore, the gas mist generating device 1 of the present invention can prevent the heating element 32 from being erroneously triggered, and when not in use, the gas mist generating device 1 forms the first air flow path, so that the heating element 32 does not operate even if sucked through the mouthpiece 13, and the smoke liquid does not flow into the atomizing chamber 31, thereby preventing liquid leakage. When needs use, aerial fog production device 1 forms second air current route, through article suction opening 13 suction, flows into the tobacco juice in the atomizing chamber 31, and heat-generating body 32 work produces aerial fog and supplies the user to pass through article suction opening 13 suction, has promoted user's suction and has experienced.
In other words, the liquid outlet 24 of the liquid reservoir 20 is closed in the unused state. The first opening 21 is open and when the aerosol generating system is in use, liquid smoke does not flow out and ambient air flows from the first opening 21 to the mouthpiece 13 when the system is drawn through the mouthpiece 13. The pressure is not transmitted to the air pressure sensor, and the air pressure sensor is shielded, so that dry burning caused by starting the heating body 32 is avoided. When the cigarette holder is used, the cigarette holder 10 and the shell 11 are controlled to move relatively, the liquid outlet 24 of the liquid storage part 20 is opened, and the cigarette liquid can flow out to the heating body 32 or the oil guiding buffer memory body in the atomization part 30. Meanwhile, the first opening 21 is shielded due to displacement and is in a closed state, air cannot be supplied to the outside, and air pressure needs to flow into the atomizing area 30 from the lower portion, so that the pressure sensor can sense the air pressure, that is, the air pressure sensor can sense suction pressure and trigger the circuit to be switched on. The first air flow path and the second air flow path have different air path circulation tracks and have different effects on the air pressure sensor.
Preferably, the aerosol-generating device 1 of the present invention exists in a first state and a second state. Referring to fig. 1, 3 and 4, in the first state, the first opening 21 is in an open state, the first opening 21 is communicated with the outside, the atomizing part 30 stops working, and no smoke liquid flows into the atomizing chamber 31. Referring to fig. 2, 5 and 6, in the second state, the first opening 21 is in a closed state, the first opening 21 is isolated from the outside, the atomizing part 30 is operated, and the smoke liquid flows into the atomizing chamber 31.
Preferably, the mouthpiece 10 is capable of moving relative to the housing 11 in a direction toward (direction a in fig. 1) or away (direction B in fig. 2) from the housing 11 to open or close the first opening 21, wherein the distance (indicated by H in fig. 4) over which the mouthpiece 10 and the housing 11 move relative to each other is not less than 0.5 mm. This is advantageous in preventing the heat-generating body 32 in the atomizing chamber 31 from being dried. Preferably, when the mouthpiece 10 and the housing 11 are moved against each other, the smoke liquid flows into the atomization chamber 31.
In this embodiment, the mouthpiece 10 can move relative to the housing 11 in a direction toward the housing 11 (direction a in fig. 1) to close the first opening 21, or the mouthpiece 10 can move relative to the housing 11 in a direction away from the housing 11 (direction B in fig. 2) to open the first opening 21. The relative movement of the mouthpiece 10 and the housing 11 of the present invention is not limited thereto and in other embodiments the relative movement of the mouthpiece 10 and the housing 11 is generated in the circumferential direction to effect opening or closing of the first opening 21.
Preferably, the air intake area of the first air flow path is not less than 50% of the air intake area of the second air flow path. This is advantageous in that when the aerosol-generating device 1 has the first airflow path, the pressure sensor does not sense pressure and the pressure sensor is not triggered; when the second air flow path is present in the gas mist generating apparatus 1, the air pressure needs to flow from the lower portion into the atomizing part 30 so that the pressure sensor can sense the air pressure, that is, the air pressure sensor can sense the suction pressure and the trigger circuit is turned on.
With continued reference to fig. 1 and 2, the aerosol-generating device 1 of the present invention further includes a second opening 22 disposed in the housing 11, and the second airflow path includes external air flowing from the second opening 22 into the nebulizing chamber 31. That is, the mouthpiece 10 and the housing 11 are relatively moved to open the first opening 21, so that when a user sucks through the mouthpiece 13, external air can flow into the aerosol channel through the first opening 21 and then flow out of the mouthpiece 13, thereby forming a first airflow path. Ambient air does not flow into the aerosol passage through the second opening 22. And the cigarette holder 10 and the outer shell 11 generate relative movement to close the first opening 21, when a user sucks through the product suction opening 13, external air can flow into the atomizing cavity 31 through the second opening 22, then flows into the aerosol channel from the atomizing cavity 31, and then flows out from the product suction opening 13 to form a second air flow path. The external air does not flow into the aerosol passage through the first opening 21.
That is, when the first opening 21 is in the open state, the user sucks air through the mouthpiece 13, external air does not flow into the aerosol passage through the second opening 22, no air flows through the atomizing chamber 31, and the air pressure sensor is not triggered; when the first opening 21 is in a closed state, a user sucks air through the product suction opening 13, outside air does not flow into the aerosol passage through the first opening 21 but flows into the atomizing chamber 31 through the second opening 22, the air pressure sensor is triggered, and fresh air mixed with aerosol generated by the aerosol flows into the atomizing chamber 31 and then flows into the aerosol passage through the atomizing chamber 31 for the user to suck through the product suction opening 13.
Preferably, the first opening 21 is closer to the product suction opening 13 than the second opening 22 in a direction from the mouthpiece 10 to the housing 11 (a direction shown in fig. 1). This is advantageous in that when the aerosol-generating device 1 has the first airflow path, the outside air does not flow into the nebulization chamber 31 through the second opening 22, but flows into the nebulization channel through the first opening 21, so that the pressure sensor does not sense the pressure and the air pressure sensor is not triggered.
It should be noted that the number, specific position and size of the first openings 21 are not limited, and the first airflow path and the second airflow path of the aerosol-generating device 1 can be satisfied. In this embodiment, referring to fig. 7, the cigarette holder 10 of the present invention has an insertion end 14, the insertion end 14 is movably disposed at one end of the first inner cavity 11a, the first opening 21 is disposed at the insertion end 14, and fig. 7 shows that two first openings 21 are disposed on the insertion end 14. After the insertion end 14 of the mouthpiece 10 is inserted into the first inner cavity 11a of the housing 11 in a direction toward the housing 11 (indicated by a direction in fig. 1), referring to fig. 2, the first opening 21 on the mouthpiece 10 is shielded such that the first opening 21 is in a closed state; when the insertion end 14 of the mouthpiece 10 is moved relative to the first inner cavity 11a of the housing 11 in a direction away from the housing 11 (indicated by direction B in fig. 2), referring to fig. 1, the first opening 21 on the mouthpiece 10 is exposed, so that the first opening 21 is in an open state. Preferably, when the insertion end 14 of the mouthpiece 10 is moved relative to the first inner cavity 11a of the housing 11 in a direction away from the housing 11, the first opening 21 of the mouthpiece 10 is shielded such that the first opening 21 is in a closed state. When the insertion end 14 of the mouthpiece 10 is moved relative to the first inner cavity 11a of the housing 11 in a direction toward the housing 11, the first opening 21 on the mouthpiece 10 is exposed, so that the first opening 21 is in an open state.
The arrangement of the first opening 21 is not limited to this, and it is sufficient that the mouthpiece 10 and the housing 11 are relatively moved to open or close the first opening 21 to form a first airflow path or a second airflow path. In other embodiments, the first opening 21 is provided on the outer shell 11, and the first opening 21 is opened or closed after the relative movement between the mouthpiece 10 and the outer shell 11 is generated.
With continued reference to fig. 3, the mouthpiece 10 of the present invention is elastically supported to the housing 11 by the first elastic member 40, and the first elastic member 40 is compressed or stretched during the relative movement between the mouthpiece 10 and the housing 11 to open or close the first opening 21. In the present embodiment, the mouthpiece 10 and the housing 11 move relative to each other in a direction toward the housing 11, and the first elastic member 40 is compressed; the mouthpiece 10 and the housing 11 move relatively in a direction away from the housing 11, the first elastic member 40 stretches, and the first elastic member 40 is restored. Preferably, referring to fig. 1, in the initial state of the aerosol-generating device 1, the first elastic member 40 is in the original state and is not compressed, and under the elastic force of the first elastic member 40, the mouthpiece 10 is elastically supported on the housing 11, and the first opening 21 is in the open state; when the user desires to draw on the aerosol-generating system, the mouthpiece 10 is controlled to move relative to the housing 11 in a direction towards the housing 11, i.e. the mouthpiece 10 is pressed, at which time the first resilient member 40 is compressed. When the smoking is finished, the mouthpiece 10 is controlled to move relative to the housing 11 in a direction away from the housing 11, and the first elastic member 40 is reset.
Furthermore, with reference to fig. 2 and 5, the mouthpiece 10 of the present invention can be moved in a direction towards the outer shell 11 against one end of the outer shell 11 to close the first opening 21, the first elastic member 40 being compressed; referring to fig. 1 and 3, the mouthpiece 10 can move in a direction away from the housing 11 to be separated from the one end of the housing 11 to open the first opening 21, and the first elastic member 40 is reset.
In addition, one of the end of the mouthpiece 10 located in the first inner cavity 11a and the inner wall of the first inner cavity 11a is provided with a convex portion, and the other end is provided with a concave portion, and the concave portion and the convex portion are matched for limiting the terminal position of the movement of the mouthpiece 10 in the direction away from the shell 11. In this embodiment, referring to fig. 3, a convex portion 15 is disposed at one end of the cigarette holder 10 located in the first inner cavity 11a, a concave portion 23 is disposed on an inner wall of the first inner cavity 11a, the concave portion 23 is matched with the convex portion 15, and after the cigarette holder 10 moves a distance in a direction away from the housing 11, the concave portion 23 and the convex portion 15 abut against each other in the moving direction of the cigarette holder 10, so as to limit the cigarette holder 10 from moving further. That is, the existence of the concave portion 23 and the convex portion 15 not only enables the mouthpiece 10 to be elastically supported in the housing 11, but also restricts the mouthpiece 10 from continuing to move when the mouthpiece 10 moves to the end position relative to the housing 11, and prevents the mouthpiece 10 from sliding out of the first inner cavity 11a of the housing 11.
Referring to figure 3, the aerosol-generating device 1 of the present invention further comprises: a liquid storage part 20, wherein tobacco liquid is stored in the liquid storage part 20, the liquid storage part 20 is provided with a liquid outlet 24, the liquid outlet 24 is closed when the cigarette holder 10 and the shell 11 generate relative movement to open the first opening 21, and the liquid outlet 24 is opened when the cigarette holder 10 and the shell 11 generate relative movement to close the first opening 21. That is, the gas mist generating device 1 does not allow the smoke liquid to flow into the atomizing area 30 in the unused state, and prevents the smoke liquid from flowing into the atomizing area 30 to cause leakage in the used state. Accordingly, the gas mist generating apparatus 1 of the present invention controls the outflow of the smoke liquid in the liquid reservoir 20 by the relative movement of the housing 11 and the mouthpiece 10.
Preferably, the reservoir 20 and the mouthpiece 10 move synchronously during the relative movement between the mouthpiece 10 and the housing 11 to open or close the first opening 21. The connection mode of the mouthpiece 10 and the liquid reservoir 20 is not limited, and the simultaneous movement may be achieved. Preferably, the mouthpiece 10 and the reservoir 20 are linked by a snap, moving synchronously when pushed. Further preferably, the mouthpiece 10 is threadedly connected to the reservoir 20. Still further preferably, the mouthpiece 10 and the reservoir 20 are bolted.

In this embodiment, the valve body 26 can move in a direction toward the first blocking portion 27 to open the liquid outlet 24, and the second elastic member 25 is compressed; alternatively, the valve body 26 can move in a direction away from the first stopper 27 to abut against the second stopper 28 to close the liquid outlet 24, and the second elastic member 25 is reset. Preferably, the distance (shown in H in fig. 4) that the valve body 26 moves in the direction toward the first stopper 27 to open the liquid outlet 24 is not less than 0.5 mm. Preferably, the valve body 26 moves at least 0.5mm before the valve body 26 moves in a direction towards said first stop 27 to open said outlet opening 24. This facilitates prevention of dry burning of the heat-generating body 32 in the atomizing chamber 31.
In other words, the mouthpiece 10 of the present invention can be moved in a direction towards the housing 11 against one end of the housing 11 to close the first opening 21, the first resilient member 40 being compressed; meanwhile, the valve body 26 can move in the direction toward the first blocking portion 27 to open the liquid outlet 24, the second elastic member 25 is compressed, the liquid outlet 24 of the liquid storage portion 20 is opened, and the smoke liquid can flow out to the heating element 32 or the oil guiding buffer memory in the atomizing portion 30; the air pressure sensor can sense the suction pressure and trigger the circuit to be connected.
Alternatively, the mouthpiece 10 can be moved in a direction away from the housing 11 to be separated from the one end of the housing 11 to open the first opening 21, and the first elastic member 40 is reset; meanwhile, the valve body 26 can move in a direction away from the first blocking portion 27 to abut against the second blocking portion 28 to close the liquid outlet 24, the second elastic member 25 is reset, and the liquid outlet 24 of the liquid storage portion 20 is closed; the pressure is not transmitted to the air pressure sensor, and the air pressure sensor is shielded, so that dry burning caused by starting the heating body 32 is avoided.
