The utility model provides an electronic atomization device 100.

In particular, the electronic atomization device 100 can be used to generate an aerosol from an atomized medium. As shown in fig. 1 and 2, the electronic atomizer 100 of the present embodiment includes an atomizer 20 and a power supply module 30. The atomizer 20 and the power supply assembly 30 are detachably connected. The atomizer 20 has a reservoir 51 for an atomizing medium.

The electronic atomizer 100 further includes a connecting assembly 40, the atomizer 20 is connected to the power supply assembly 30 through the connecting assembly 40, so as to supply power to the atomizer assembly 60 in the atomizer 20 through the power supply assembly 30, and the atomizer assembly 60 converts the electric energy supplied by the power supply assembly 30 into heat energy and heats the atomization medium. The user draws the mouthpiece end of the atomizer 20 through the mouth, i.e. can inhale the aerosol. In some embodiments, the nebulizing medium is a tobacco liquid or a liquid drug for treatment.

When the atomized medium in the reservoir chamber 51 is used up, the atomizer 20 needs to be replaced from the power module 30, and the atomizer 20 can be detached and a new atomizer 20 can be mounted on the power module 30, thereby realizing the reuse of the power module 30.

The present invention also provides an atomizer 20.

In some embodiments, as shown in fig. 3-7, the atomizer 20 comprises: the atomizing device comprises a housing assembly 50, an atomizing assembly 60 accommodated in the housing assembly 50, and a suction nozzle assembly 70 penetrating the housing assembly 50. The housing assembly 50 has a reservoir chamber 51. The atomizing assembly 60 has an inlet orifice 601 for the flow of an atomizing medium. The nozzle assembly 70 is used to define at least a portion of the boundary of the reservoir 51. The nozzle assembly 70 has a first state and a second state. The nozzle assembly 70 covers the inlet 601 in the first state to restrict the flow of the atomized medium in the reservoir 51 into the atomizing assembly 60. In the second state, the nozzle assembly 70 releases the liquid inlet 601 from the cover, so that the atomized medium in the reservoir 51 can flow into the atomization assembly 60 through the liquid inlet 601.

When the atomizing assembly 60 is transported and stored or the user is temporarily not used, the suction nozzle assembly 70 is switched to the second state, so that the liquid inlet hole 601 of the atomizing assembly 60 is covered by the suction nozzle assembly 70, the atomizing medium in the liquid storage cavity 51 is prevented from leaking from the liquid inlet hole 601, and waste is avoided. Meanwhile, the atomized medium is prevented from entering the atomization assembly 60 or the suction nozzle assembly 70 through the liquid inlet 601 and contacting with the air flow, and the atomized medium is prevented from being oxidized and deteriorated. When a user needs to use the atomizer 20, the suction nozzle assembly 70 is operated to cut the suction nozzle assembly 70 from the first state to the second state, the liquid inlet hole 601 is uncovered, the atomized medium in the liquid storage chamber 51 enters the atomizing assembly 60 through the liquid inlet hole 601, the atomized medium is heated by the atomizing assembly 60 to form aerosol, and the aerosol flows from the atomizing assembly 60 to the suction nozzle assembly 70 under the action of the suction airflow of the user, finally flows out from the suction nozzle assembly 70, and is sucked by the user.

Specifically, the atomizer 20 forms an air flow path between the atomizing assembly 60 and the nozzle assembly 70. During normal use of the nebulizer 20, the aerosol flows along the airflow path to be inhaled by the user.

In some embodiments, the power module 30 includes a casing 31 and an electric core 32 accommodated in the casing 31. Specifically, the connection assembly 40 houses the sheath 31, the connection assembly 40 having an electrical terminal 41 for transferring electrical energy of the cell 32 to the atomizer 20. In the embodiment shown in fig. 2, the combination connection between the atomizer 20 and the power supply module 30 is achieved by inserting the housing module 50 into the casing 31, with an interference fit between the housing module 50 and the casing 31. The atomizing assembly 60 is simultaneously mated with the electrical terminals 41 after being inserted into place within the shroud 31.

In some embodiments, the housing assembly 50 includes a shell 52. The housing 52 is provided with an opening 521, and the nozzle assembly 70 is movably disposed through the opening 521. Further, in the embodiment shown in fig. 3, to avoid leakage of the atomized medium from the gap between the edge of the opening 521 and the nozzle assembly 70, the housing assembly 50 further comprises a second seal 53 abutting between the edge of the opening 521 and the nozzle assembly 70. Specifically, the second seal 53 nests inside the edge of the opening 521 and is disposed around the nozzle assembly 70. More specifically, the second seal 53 is flexible to accommodate the gap between the edge of the opening 521 and the nozzle assembly 70.

In some embodiments, the housing assembly 50 further includes a base 54 that is coupled to the outer shell 52. The base 54 is coupled to the atomizing assembly 60 and retains the atomizing assembly 60 within the housing 52. In the embodiment shown in fig. 3, the housing 52, the base 54, and the nozzle assembly 70 each form an interior wall of the reservoir 51.

Further, the housing assembly 50 further includes a third seal 55 abutting between the outer shell 52 and the base 54 and a fourth seal 56 abutting between the atomizing assembly 60 and the base 54. Specifically, a third seal 55 is provided around the base 54 to prevent the atomized medium from leaking out of the gap between the base 54 and the housing 52. A fourth seal 56 is disposed about the atomizing assembly 60 to prevent the atomizing medium within the reservoir 51 from leaking out of the gap between the atomizing assembly 60 and the base 54.

More specifically, in the embodiment shown in fig. 3, the base 54 includes an inner housing 541 and an outer housing 542, and the inner housing 541 is used to cooperate with the atomizing assembly 60 and the housing 52 to form a boundary of the liquid storage chamber 51. The third sealing member 55 abuts between the inner housing 541 and the atomizing assembly 60. An air inlet 543 is further formed on the outer seat 542, a cavity communicating with the inside of the atomizing assembly 60 is formed between the inner seat 541 and the outer seat 542, and an external air flow sequentially passes through the air inlet 543 and the cavity to enter the atomizing assembly 60. The fourth sealing member 56 abuts between the atomizing assembly 60 and the outer housing 542. The outer base 542 is connected to a magnet 544, and when the atomizer 20 is connected to the power module 30, the magnet 544 and the connecting module 40 are magnetically attracted to each other, so that the atomizer 20 is retained in the casing 31.

Further, the housing 52 is provided with a liquid injection port to inject the atomized medium into the liquid storage chamber 51. In the embodiment shown in fig. 4, the atomizing assembly 60 further includes a seal-side cover 522 for blocking the liquid injection port.

In some embodiments, the atomizing assembly 60 includes an atomizing sleeve 61, a liquid guiding member 62 received in the atomizing sleeve 61, and a heat generating member 63 received in the liquid guiding member 62. The liquid inlet hole 601 is disposed in the atomizing sleeve 61, and the atomizing sleeve 61 is provided with a mist outlet 602 for outputting aerosol. In the second state, the atomized medium enters the atomizing sleeve 61 through the liquid inlet hole 601 and is absorbed by the liquid guiding member 62. The heat generating member 63 is attached to the inner wall of the liquid guiding member 62 or formed in the liquid guiding member 62, and generates heat to form aerosol from the atomized medium absorbed by the liquid guiding member 62. Specifically, the liquid guide 62 is porous ceramic.

Further, the atomizing assembly 60 further includes a liquid absorbing member 64 disposed between the liquid guiding member 62 and the atomizing sleeve 61, the liquid absorbing member 64 is disposed around the liquid guiding member 62, and after the atomized medium is absorbed by the liquid absorbing member 64 through the liquid inlet hole 601, the atomized medium is diffused by the liquid absorbing member 64, so that the atomized medium can be absorbed by the liquid guiding member 62 from different angles. Specifically, the absorbent member 64 is absorbent cotton.

Further, the atomizing assembly 60 further includes an atomizing base 65, and the atomizing base 65 is provided with a main base body 651 and an auxiliary base body 652. The main body 651 has a plurality of pressing pieces 653, and the pressing pieces 653 are disposed around the liquid guide 62 to limit the liquid guide 62. In the embodiment shown in fig. 3, the wicking member 64 is sleeved outside the pressing piece 653 and inside the atomizing sleeve 61. The gap between the main seat body 651 and the auxiliary seat body 652 is communicated with the cavity, so that the air flow enters the liquid guide member 62 in the second state, and the aerosol is driven to flow. More specifically, as shown in fig. 3, the main seat body 651 and the sub seat body 652 are respectively formed with annular grooves for retaining the third seal member 55.

In the embodiment shown in fig. 3, the input terminal 654 electrically connected to the heat generating material 63 is fitted into the sub-base 652, and after the atomizer 20 is fitted into the casing 31, the input terminal 654 is brought into contact with the electrical terminal 41, so that the power supply module 30 can supply electric current to generate heat. Further, the atomization assembly 60 also includes a sealing plug 655 disposed between the secondary seat 652 and the input terminal 654 to prevent the atomized medium from leaking into the power module 30 through the gap between the input terminal 654 and the secondary seat 652.

In some embodiments, the suction nozzle assembly 70 is removably disposed through the housing assembly 50. The nozzle assembly 70 has a suction end 701 exposed from the housing assembly 50 and a receiving end 702 embedded in the housing assembly 50. The liquid inlet hole 601 is received in the receiving end 702 in the first state and exposed out of the receiving end 702 in the second state. The receiving end 702 at least partially covers the atomizing assembly 60 in the second state. In the embodiment shown in fig. 6 and 7, the suction nozzle assembly 70 is inserted into and removed from the housing assembly 50, and the inner wall of the atomizing assembly 60 having the liquid inlet 601 is received in the receiving end 702 of the suction nozzle assembly 70 by inserting the housing assembly 50 along the axial direction of the suction nozzle assembly 70, so that the suction nozzle assembly 70 can block the atomized medium and limit the atomized medium from flowing into the atomizing assembly 60 through the liquid inlet 601. More specifically, the edges of the receiving end 702 are rounded to facilitate machining of the nozzle assembly 70. In the second state, since the receiving end 702 still covers the atomizing element 60, a significant gap between the receiving end 702 and the atomizing element 60 can be avoided, and the atomized medium can be prevented from flowing into the nozzle assembly 70 directly.

In an embodiment not shown, the suction nozzle assembly 70 may be rotatably disposed with respect to the housing assembly 50 and switched between the first state and the second state by rotating along its axis. The edge of the receiving end 702 is concave-convex in the axial direction so as to cover the liquid inlet hole 601 at an angle corresponding to the first state and to contact the liquid inlet hole 601 at an angle corresponding to the second state.

In the embodiment shown in fig. 4, the nozzle assembly 70 includes a tube 71, one end of the tube 71 is used as a suction end 701, and the other end is used as a receiving end 702. Further, the nozzle assembly 70 further includes a first sealing member 72 abutting between the tube 71 and the atomizing assembly 60 to limit the atomized medium in the reservoir 51 from entering the tube 71 through a gap between the tube 71 and the atomizing assembly 60. More specifically, the first sealing member 72 is disposed near the receiving end 702 of the tube body 71, and the tube body 71 is provided with a stopper groove for receiving the first sealing member 72 at an inner wall of the receiving end 702. In the embodiment shown in fig. 4, the first seal 72 is provided in a cylindrical shape and has flexibility, and a rib 721 extends from an inner wall thereof, and the rib 721 abuts against the surface of the atomizing sleeve 61, whereby resistance when the first seal 72 moves relative to the atomizing sleeve 61 can be reduced, and a sealing effect can be ensured.

In some embodiments, the nozzle assembly 70 has a stop surface 712, and the stop surface 712 is configured to abut the housing assembly 50 in the second state to limit the nozzle assembly 70 from being completely withdrawn from the housing assembly 50. In the embodiment shown in fig. 4, the pipe 71 has the retainer ring 713 extending therefrom, and the stopper surface 712 is provided on the retainer ring 713, so that when the suction nozzle is pulled out with respect to the housing unit 50 until the retainer ring 713 abuts against the housing unit 50, the pipe 71 is prevented from being completely pulled out. In an embodiment not shown, a step may be provided on the tube 71, and the two stoppers are located on the step.

In some embodiments, the nozzle assembly 70 blocks the airflow path in the first state and unblocks the airflow path in the second state. Since the atomizer 20 is in the first state when the atomizer 20 is not in use, the air flow path is blocked by the nozzle assembly 70, thereby blocking the external air flow through the atomizing assembly 60. Further, since the atomizer 20 triggers the heating of the atomizing assembly 60 by detecting the airflow in the airflow channel, and the nozzle assembly 70 restricts the airflow passing through the airflow channel in the first state, the heating of the atomizing assembly 60 triggered by the airflow can be avoided, and the problem of dry burning of the atomizing assembly 60 in the first state can be prevented.

In some embodiments, the nozzle assembly 70 has an inner bayonet 711, and the air flow channel in the second state flows through the inner bayonet 711 and the mist outlet 602. The atomizing assembly 60 further includes a through-flow member 73, the through-flow member 73 has a baffle portion 731 and a side wall portion 732 connecting with one side of the baffle portion 731, and the side wall portion 732 has a side port 733 communicating with an inner cavity thereof.

In the embodiment shown in fig. 4, the side wall portion 732 is connected to the inner clamp 711, and the shutter portion 731 closes the mist outlet 602 in the first state. Specifically, the inner bayonet 711 is provided to the tube body 71, and the tube body 71 communicates with the inner cavity of the side wall portion 732 through an inner space between the inner bayonet 711 and the suction end 701. In the first state, since the surface area of the baffle portion 731 is larger than the area of the mist outlet 602, the interface between the baffle portion 731 and the edge of the mist outlet 602 prevents the airflow from passing through the mist outlet 602, and the airflow passage can be blocked. In the second state, since the baffle portion 731 is away from the mist outlet 602, the airflow flows out from the mist outlet 602, bypasses the baffle portion 731, enters the inner cavity of the through-flow member 73 from the side port 733 of the side wall portion 732, and then flows to the suction end 701 through the inner space of the tube 71.

Further, as shown in fig. 4, the inner bayonet 711 is changed in a stepwise transition manner, and the side wall portion 732 is fitted into the inner bayonet 711. And the side wall portion 732 abuts against the inner wall of the nozzle assembly 70 in the relative movement direction of the nozzle assembly 70 and the atomizing assembly 60, i.e., in the axial direction of the nozzle assembly 70. Since the side wall portion 732 is supported by the tube body 71, the through-flow member 73 is prevented from being displaced when the baffle portion 731 abuts against the edge of the mist outlet 602.

In an embodiment not shown, the side wall 732 is connected to the mist outlet 602, and the baffle portion 731 closes the inner clamp 711 in the first state. Specifically, the surface area of baffle portion 731 is larger than the area of inner bayonet 711, so that when the surface of baffle portion 731 abuts the edge of inner bayonet 711, the air flow is prevented from passing through inner bayonet 711, and the air flow passage can be blocked.

In the embodiment shown in fig. 6, in a case where the atomizer 20 is not required to be used, the tube 71 can be pushed to move deeply into the housing assembly 50 by pushing the suction end 701 of the tube 71, and the volume of the atomizing sleeve 61 accommodated in the accommodating end 702 of the tube 71 is increased. When the receiving end 702 of the tube 71 abuts the base 54, the portion of the atomizing assembly 60 that protrudes out of the base 54 is completely received within the receiving end 702. Along the axial direction of the atomizing sleeve 61, the outer walls of the atomizing sleeve 61 on the two sides of the liquid inlet hole 601 are attached by the convex rib 721 of the first sealing element 72, so that the liquid inlet hole 601 is blocked by the first sealing element 72, and the atomized medium cannot flow into the liquid storage cavity 51. In the first state, since the mist outlet 602 is abutted by the baffle portion 731, no air flow is generated between the air inlet hole 543 and the suction end 701 of the tube 71, and heating of the heat generating member 63 is prevented from being triggered. In one embodiment, the atomizer 20 detects the sound of the air flow between the air inlet hole 543 and the suction end 701 of the tube 71, and triggers the power supply assembly 30 to output the current to the heat generating component 63 after the sound generated by the air flow is identified by the sound detection.

In the embodiment shown in fig. 7, in a case where the nebulizer 20 is to be used, the suction end 701 of the tube 71 is pulled out, and the tube 71 is moved in a direction of withdrawing from the housing assembly 50 until the stopper surface 712 abuts against the second seal 53. At this time, the portion of the atomizing sleeve 61 where the liquid inlet hole 601 is provided is exposed from the receiving end 702 of the tube 71 and the first seal 72, and the atomized medium in the reservoir chamber 51 flows into the atomizing sleeve 61 through the liquid inlet hole 601 and is absorbed by the liquid absorbing member 64 and the liquid guiding member 62 in a large amount. Specifically, the pressing piece 653 has a through hole, so that the atomizing medium can flow through the pressing piece 653 to the liquid guide 62. Meanwhile, since the receiving end 702 of the tube 71 and the first sealing element 72 are still sleeved on a part of the atomizing sleeve 61 in the second state, the atomized medium in the liquid storage chamber 51 is prevented from directly flowing into the tube 71. In the second state, the baffle portion 731 is away from the mist outlet 602, and the mist outlet 602 can communicate with the side port 733 through the gap between the baffle portion 731 and the inner wall of the pipe body 71, thereby communicating the air flow passage. When a user inhales from the suction end 701, the air flow passes through the air inlet hole 543, the inside of the atomizing assembly 60, the mist outlet 602, the side port 733 and the suction end 701 in sequence. The gas flow in the air flow channel triggers the heating element 63 to generate heat, so that the atomized medium in the liquid guide element 62 forms aerosol, and the aerosol is driven by the air flow to the suction end 701 of the tube 71 and be sucked by the user.
