An aerosol-generating device

Abstract

This invention discloses an aerosol generating device, comprising: a nozzle, a pull rod, a liquid storage chamber, and a gas-liquid valve. The liquid storage chamber has a partition tube, and the space between the inner wall of the liquid storage chamber and the outer wall of the partition tube is used to store atomizing liquid. The partition tube has a liquid inlet. The nozzle has a first sleeve, which is sleeved on the first end of the pull rod. The second end of the pull rod is inserted into the partition tube. The gas-liquid valve is connected to the second end of the pull rod. The nozzle and the liquid storage chamber are rotatably connected. When the nozzle rotates, it can cause the first sleeve to drive the pull rod to move axially, thereby causing the gas-liquid valve to close or open the liquid inlet. The axial movement of the pull rod of the aerosol generating device of this invention can drive the gas-liquid valve to move axially within the partition tube. When the gas-liquid valve moves to a position opposite to the liquid inlet, it can block the liquid inlet and cut off the liquid supply channel of the aerosol generating device. Therefore, the liquid supply channel can be opened or closed by rotating the nozzle, preventing leakage when not in use or during transportation.

The outer wall of the first end of the liquid storage chamber has a limiting groove extending circumferentially. The inner wall of the third sleeve has a protrusion inserted into the limiting groove. The limiting groove has a first end and a second end. When the protrusion is located at the first end, the gas-liquid valve closes the liquid inlet. When the protrusion is located at the second end, the gas-liquid valve opens the liquid inlet.

[0024] Compared with the prior art, the aerosol generating apparatus of the present invention has at least the following beneficial effects:

[0025] This invention discloses an aerosol generating device, comprising: a nozzle, a pull rod, a liquid storage chamber, and a gas-liquid valve. The liquid storage chamber has a partition tube, and the space between the inner wall of the liquid storage chamber and the outer wall of the partition tube is used to store atomizing liquid. The partition tube has a liquid inlet. The nozzle has a first sleeve, which is sleeved on the first end of the pull rod, and the second end of the pull rod is inserted into the partition tube. The gas-liquid valve is connected to the second end of the pull rod. The nozzle and the liquid storage chamber are rotatably connected. When the nozzle rotates, it can cause the first sleeve to drive the pull rod to move axially, thereby causing the gas-liquid valve to close or open the liquid inlet. Specifically, the inner wall of the first sleeve cooperates with the first end of the pull rod. When rotated, the first sleeve rotates, which can drive the pull rod to move axially. The second end of the pull rod is inserted into the separator tube, and the gas-liquid valve is connected to the second end of the pull rod. Therefore, the axial movement of the pull rod can drive the gas-liquid valve to move axially within the separator tube. When the gas-liquid valve moves to a position opposite to the liquid inlet, it can block the liquid inlet and cut off the liquid supply channel of the aerosol generating device. When the gas-liquid valve moves to a position offset from the liquid inlet, it opens the liquid supply channel of the aerosol generating device. Therefore, the aerosol generating device of the present invention can open and close the liquid supply channel by rotating the suction nozzle, and can prevent leakage when not in use or during transportation.

[0034] like Figure 1 As shown, an aerosol generating device provided in an embodiment of the present invention includes:

[0035] The device includes a nozzle 1, a pull rod 3, a liquid storage chamber 4, and a gas-liquid valve 5. The liquid storage chamber 4 has a partition tube 6. The space between the inner wall of the liquid storage chamber 4 and the outer wall of the partition tube 6 is used to store atomizing liquid. The partition tube 6 has a liquid inlet 61. The nozzle 1 has a first sleeve 11, which is sleeved on the first end of the pull rod 3. The second end of the pull rod 3 is inserted into the partition tube 6. The gas-liquid valve 5 is connected to the second end of the pull rod 3. The nozzle 1 and the liquid storage chamber 4 are rotatably connected. When the nozzle 1 rotates, it can drive the pull rod 3 to move axially to drive the gas-liquid valve 5 to close or open the liquid inlet 61.

[0036] In this embodiment, the aerosol generating device includes: a nozzle 1, a pull rod 3, a liquid storage tank 4, and a gas-liquid valve 5. The liquid storage tank 4 has a partition tube 6, and the space between the inner wall of the liquid storage tank 4 and the outer wall of the partition tube 6 is used to store atomizing liquid. The partition tube 6 has a liquid inlet 61. The nozzle 1 has a first sleeve 11, which is sleeved on the first end of the pull rod 3. The second end of the pull rod 3 is inserted into the partition tube 6. The gas-liquid valve 5 is connected to the second end of the pull rod 3. The nozzle 1 and the liquid storage tank 4 are rotatably connected. When the nozzle 1 rotates, the first sleeve 11 can drive the pull rod 3 to move axially to drive the gas-liquid valve 5 to close or open the liquid inlet 61. Specifically, the inner wall of the first sleeve 11 cooperates with the first end of the pull rod 3. When the suction nozzle 1 rotates, it drives the first sleeve 11 to rotate. The first sleeve 11 can drive the pull rod 3 to move axially. The second end of the pull rod 3 is inserted into the partition tube 6. The gas-liquid valve 5 is connected to the second end of the pull rod 3. Therefore, the axial movement of the pull rod 3 can drive the gas-liquid valve 5 to move axially within the partition tube 6. When the gas-liquid valve 5 moves to a position opposite to the liquid inlet 61, it can block the liquid inlet 61 and cut off the liquid supply channel of the aerosol generating device. When the gas-liquid valve 5 moves to a position offset from the liquid inlet 61, it opens the liquid supply channel of the aerosol generating device. Therefore, the aerosol generating device of the present invention can realize the opening and closing of the liquid supply channel by rotating the suction nozzle 1, and can prevent leakage when not in use or during transportation.

[0037] In some implementations...

[0038] The outer wall of the gas-liquid valve 5 is shaped to match the inner wall of the partition tube 6 so that when the gas-liquid valve 5 is moved to a position opposite to the inlet hole 61, it can block the inlet hole 61.

[0039] In this embodiment, the outer wall of the gas-liquid valve 5 is shaped to match the inner wall of the partition tube 6. For example, when the cross-section of the partition tube 6 is circular, the cross-section of the gas-liquid valve 5 is also circular; when the cross-section of the partition tube 6 is elliptical, the cross-section of the gas-liquid valve 5 is also elliptical. Of course, the cross-section of the partition tube 6 can be circular or elliptical, or it can be other shapes. The shape of the cross-section of the gas-liquid valve 5 corresponds to the shape of the cross-section of the partition tube 6, which makes the gas-liquid valve 5 fit more tightly with the inner wall of the partition tube 6, preventing leakage between the outer wall of the gas-liquid valve 5 and the partition tube 6. At the same time, when the gas-liquid valve 5 moves to a position opposite to the liquid inlet 61, it can better seal the liquid inlet 61 and open or close the liquid supply channel.

[0040] In some implementations...

[0041] The outer peripheral wall of the pull rod 3 near the first end has a spiral groove 31 that is circumferentially arranged. The inner wall of the first sleeve 11 has a pivot point inserted into the spiral groove 31. When the suction nozzle 1 rotates, the pivot point moves in the spiral groove 31 to drive the pull rod 3 to move axially.

[0042] In this embodiment, the outer peripheral wall of the pull rod 3 near the first end has a spiral groove 31 that is circumferentially arranged. The inner wall of the first sleeve 11 has a pivot point inserted into the spiral groove 31. When the suction nozzle 1 rotates, the pivot point moves in the spiral groove 31 to drive the pull rod 3 to move axially. Specifically, since the spiral groove 31 and the pivot point on the inner wall of the first sleeve 11 are mutually constrained, when the suction nozzle 1 rotates, the pivot point can apply force to the spiral groove 31 to make the pull rod 3 move axially and extend and retract. When moving, it drives the gas-liquid valve 5 to move relative to the liquid inlet 61 to realize the opening and closing of the liquid supply channel.

[0043] In some implementations...

[0044] The separator tube 6 contains an atomizing core 8, which is located on the side of the liquid inlet 61 away from the nozzle 1.

[0045] In this embodiment, the separator tube 6 has an atomizing core 8, which is located on the side of the liquid inlet 61 away from the mouthpiece 1. When the gas-liquid valve 5 opens the liquid inlet 61, the atomizing liquid in the liquid storage chamber 4 can flow into the atomizing core 8 through the liquid inlet 61. The atomizing liquid is atomized by the atomizing core 8 to generate an aerosol for the user to inhale. When the gas-liquid valve 5 opens the liquid inlet 61, the supply of atomizing liquid to the atomizing core 8 is cut off, which can prevent leakage when not in use or during transportation.

[0046] In some implementations...

[0047] The aerosol generating device also includes an air tube 7, a nozzle 1 having a second sleeve 12, the second sleeve 12 being spaced apart within a first sleeve 11, a first end of the air tube 7 being inserted into the second sleeve 12, a gas-liquid valve 5 having a cavity communicating with the atomizing core 8, a second end of the air tube being retractably inserted into the gas-liquid valve 5, the second end of the air tube 7 being in a blocked state, and an air passage 71 being provided on the outer peripheral wall of the air tube 7; when the gas-liquid valve 5 closes the liquid inlet 61, the air passage 71 is located outside the cavity; when the gas-liquid valve 5 opens the liquid inlet 61, the air passage 71 is located inside the cavity.

[0048] In this embodiment, the aerosol generating device further includes an air tube 7. The nozzle 1 has a second sleeve 12, which is spaced apart within the first sleeve 11. The first end of the air tube 7 is inserted into the second sleeve 12. The gas-liquid valve 5 has a cavity communicating with the atomizing core 8. The second end of the air tube is retractably inserted into the gas-liquid valve 5. The second end of the air tube 7 is in a blocked state. An air passage 71 is provided on the outer peripheral wall of the air tube 7. When the gas-liquid valve 5 closes the liquid inlet 61, the air passage 71 is located outside the cavity. When the gas-liquid valve 5 opens the liquid inlet 61, the air passage 71 is located inside the cavity. Since the first end of the air tube 7 is inserted into the second sleeve 12, i.e., fixed to the nozzle 1, when the nozzle 1 rotates, causing the first sleeve 11 to drive the pull rod 3 to move axially to drive the gas-liquid valve 5 to close or open the liquid inlet 61, the second end of the air tube 7 remains stationary relative to the nozzle 1, while the gas-liquid valve 5 moves relative to the nozzle 1. A retractable tube 7 is inserted into the gas-liquid valve 5. The gas-liquid valve 5 has a cavity that communicates with the atomizing core 8. The second end of the air tube 7 is in a blocked state. An air passage 71 is provided on the outer peripheral wall of the air tube 7. Therefore, when the mouthpiece 1 is rotated to the position where the gas-liquid valve 5 opens the liquid inlet 61, the gas-liquid valve 5 moves towards the mouthpiece 1, increasing the length of the air tube 7 inserted into the gas-liquid valve 5, causing the air passage 71 to move into the cavity, so that the air tube 7 communicates with the atomizing core 8 to open the airflow channel. When the mouthpiece 1 is rotated to the position where the gas-liquid valve 5 closes the liquid inlet 61, the gas-liquid valve 5 moves away from the mouthpiece 1, reducing the length of the air tube 7 inserted into the gas-liquid valve 5, causing the air passage 71 to move out of the cavity, so that the air tube 7 is disconnected from the atomizing core 8 to cut off the airflow channel. Therefore, this embodiment cuts off the airflow channel at the same time as cutting off the liquid supply channel, which can reduce the loss of aroma and leakage when not inhaling; and prevent leakage during transportation.

[0050] The pull rod 3 is a tubular structure, the air tube 7 is inserted into the pull rod 3, and an elastic component is provided between the gas-liquid valve 5 and the second end of the pull rod 3. The elastic component is sleeved on the air tube 7.

The outer wall of the first end of the liquid storage tank 4 has a limiting groove 41 extending in the circumferential direction. The inner wall of the third sleeve 13 has a protrusion inserted into the limiting groove 41. The limiting groove 41 has a first end and a second end. When the protrusion is located at the first end, the gas-liquid valve 5 closes the liquid inlet 61. When the protrusion is located at the second end, the gas-liquid valve 5 opens the liquid inlet 61.

When the protrusion is located at the first end, the gas-liquid valve 5 closes the liquid inlet 61. When the protrusion is located at the second end, the gas-liquid valve 5 opens the liquid inlet 61. In this embodiment, the first end and the second end of the limiting groove 41 cooperate with the protrusion on the inner wall of the third sleeve 13 to limit the rotation angle of the suction nozzle 1, making it easier for the user to distinguish the state of the suction nozzle 1. The first end and the second end of the limiting groove 41 can also be marked for easy identification by the user.
