Referring to fig. 1-10, an embodiment of the present utility model provides an atomizer, which includes a housing 1, an atomizing core 2, and an inertia impeller 3.

Wherein, a liquid storage bin 11 for storing atomized liquid and an air flow channel 12 communicated with the outside are arranged in the shell 1. The atomizing core 2 is arranged on the airflow path of the airflow channel 12 and is communicated with the liquid storage bin 11. The inertia impeller 3 is provided in the airflow passage 12, and the inertia impeller 3 is provided so as to be rotatable by the suction airflow when the suction airflow is formed in the airflow path of the airflow passage 12, and so as to be rotatable continuously by inertia after the suction airflow is removed, so as to discharge the mist remaining in the airflow passage 12.

The technical scheme of the embodiment has the following effects:

firstly, through setting up the inertia impeller 3 in air current passageway 12, when the user draws, can form the suction air current in air current passageway 12, the suction air current promotes the rotation of inertia impeller 3, when the user stops drawing, the suction air current can withdraw from air current passageway 12, can not form the suction air current in the air current passageway 12 at this moment, but inertia impeller 3 still can rely on inertia and keep rotatory, thereby fan the vapour fog that remains in air current passageway 12, make it discharge outside the atomizer, avoid the vapour fog to be detained in air current passageway 12 and form the condensate, and then can effectively reduce the phenomenon that the atomizer weeping appears.

And the inertia impeller 3 can discharge the residual vapor once after the second suction action is finished once by a user, so that the residence time of the vapor in the air flow channel 12 can be shortened, and condensate formed by the vapor in the air flow channel 12 can be further avoided. In addition, because the inertial impeller 3 accelerates and rotates under the pushing of the suction airflow in the suction process, the rotation speed of the inertial impeller 3 always reaches the maximum value when the suction action stops, so that the inertial impeller 3 immediately discharges the vapor remained in the airflow channel 12 with maximum efficiency and has no slow starting process when the suction is stopped, the vapor remained in the airflow channel 12 can be rapidly and efficiently discharged, the residence time of the vapor in the airflow channel 12 is shortened to the greatest extent, and the formation of condensate can be further avoided.

Thirdly, because the power source of the inertia impeller 3 is the driving force of the suction air flow, no power supply is needed to provide electric energy, the atomizer does not need to consume the electric energy of the electronic atomization device additionally in the process of removing the residual air fog, and the electronic atomization device has the advantage of zero energy consumption and residual air fog removal, namely the electronic atomization device can still maintain the original cruising ability.

Further, in an exemplary embodiment of the present utility model, as shown in fig. 1 to 4, the inertia impeller 3 includes: mounting assembly 31, shaft 32, blade 33, and counterweight 34.

Wherein the mounting assembly 31 is secured within the airflow channel 12.

The weight 34 is fixedly connected to at least the blades 33, so that each blade 33 can continuously rotate due to inertia after the suction airflow is removed, and the continuous rotation time can be prolonged, because the inertia of the inertia impeller 3 is larger, the continuous rotation time of the inertia impeller 3 is longer after the user stops suction, and the weight of the inertia impeller 3 is increased due to the arrangement of the weight 34, so that the inertia of the inertia impeller 3 is increased, and the continuous rotation time of the inertia impeller 3 due to inertia is prolonged after the user stops suction, so that the vapor remaining in the airflow channel 12 can be well fanned, and discharged outside the atomizer.

In this embodiment, in the implementation, the vane 33 and the rotating shaft 32 may be an integrally formed structure, and the vane 33 may be fixedly connected to the rotating shaft 32 by plugging or bonding, which is not limited in this embodiment.

It should be noted that, the degree of spiral twisting of the blades 33 along the axial direction or the radial direction of the rotating shaft 32 should be set according to practical needs, so long as each blade 33 can rotate around the rotating shaft 32 under the impact of the suction airflow, that is, when the suction airflow passes through the channel between every two adjacent blades 33, the spiral twisting portion on the blade 33 can be impacted, so as to generate thrust on the blade 33, so that the blade 33 can rotate around the axis of the rotating shaft 32, which is not limited herein in particular.

Further, in order to make the weight of the inertia impeller 3 uniform, so that the inertia impeller 3 can maintain dynamic balance better when rotating, thereby ensuring that each blade 33 can maintain rotation better due to inertia after the suction airflow is removed, the weight 34 can be provided in three ways:

in the first embodiment, as shown in fig. 4, the weight portion 34 is in a ring shape and is fixedly sleeved on an outer edge of one side of each blade 33 facing away from the rotating shaft 32, the weight portion 34 is coaxially disposed with the rotating shaft 32, and the weight portion 34 may be located on the blade 33 along two ends or between two ends of the rotating shaft 32 in the axial direction, which is not limited herein.

In the second mode, the weight portion 34 may also be in a block shape (not shown), the weight portion 34 is fixed on each blade 33, and the weight portions 34 on each blade 33 are rotationally symmetrically arranged around the rotating shaft 32. Specifically, each vane 33 is provided with a weight 34, or the same weight 34 is provided on the adjacent vanes 33, so long as the weight of the inertia impeller 3 can be made uniform and dynamic balance can be maintained during rotation, and the present utility model is not limited thereto.

Because the inertia impeller 3 is disposed in the air outlet channel 122, the air flow generated by inertial rotation can be wholly discharged outwards along the air outlet channel 122, so that the residual air in the air outlet channel 122 is prevented from drifting towards the air inlet channel 121 to prolong the retention time, and the effect of efficiently discharging the residual air is achieved. In addition, compared with the axis of the air outlet channel 122 being intersected with the axis of the rotating shaft 32, the axis of the rotating shaft 32 is parallel to or coincident with the axis of the air outlet channel 122, so that not only is the obstruction to the suction air flow less, but also the circulation of the suction air flow is facilitated, the direction of the air flow generated by the inertial rotation of the inertial impeller 3 is the same as the extending direction of the air channel, and the inertial impeller 3 is more beneficial to blowing out the residual vapor along the air outlet channel 122. In addition, in the embodiment, the inertia impeller 3 may be disposed directly above the atomizing core 2, or may be disposed directly below the atomizing core 2, as long as the mist staying in the air outlet passage 122 can be blown out of the atomizer, which is not particularly limited in this embodiment, and the inertia impeller 3 is disposed directly above the atomizing core 2, as shown in fig. 1 to 4, for example.

In addition, a distance exists between the side of the connecting portion 313 close to the rotating shaft 32 and the side of each blade 33 away from the rotating shaft 32, so that the blades 33 can be prevented from being blocked by the connecting portion 313 and not being rotated when rotating around the axis of the rotating shaft 32.

The tip 321 of the rotating shaft 32 is abutted in the groove of the fourth positioning portion 14 and realizes a rotating fit, thus reducing the rotating shaft 32 and the accommodating cavity 13The friction between the walls reduces the resistance of the inertia impeller 3 during inertial rotation, which is beneficial to prolonging the period of inertial rotation of the inertia impeller 3 and further is beneficial to more thoroughly exhausting the vapor remained in the airflow channel 12.

To enable the impeller 3 to rotate under the impact of the suction air flow and to continue to rotate due to inertia after the suction air flow is removed, and to extend the duration of the continuous rotation, in a further exemplary embodiment of the present utility model, the impeller 3 may be further configured as follows:

specifically, referring to fig. 2 and 11, the inertia impeller 3 includes: mounting assembly 31, spindle 32 and vane 33. The mounting assembly 31 is secured within the airflow passage 12. The rotating shaft 32 is rotatably connected with the mounting assembly 31, and the rotating shaft 32 extends along the air outlet direction of the air flow channel 12, specifically, the axis of the rotating shaft 32 may be parallel or coincident with the axis of the air outlet channel 122. The blades 33 are connected with the rotating shaft 32, the blades 33 are provided with a plurality of blades 33, the plurality of blades 33 are arranged at intervals along the periphery of the rotating shaft 32, each blade 33 is of a sheet-shaped structure which is spirally twisted and extended along the axial direction of the rotating shaft 32, and each blade 33 can rotate around the rotating shaft 32 under the impact of suction airflow. Moreover, in the axial direction of the rotating shaft 32, the thickness of one end of each vane 33 is larger than the thickness of the rest of the vane 33 (for example, the thickness of the lower end of each vane 33 may be set to be larger than the thickness of the rest of the vane 33), the thickness of the rest of the vane 33 is uniformly set, or, in the radial direction of the rotating shaft 32, the thickness of one end of each vane 33 facing away from the rotating shaft 32 is larger than the thickness of the rest of the vane 33, the thickness of the rest of the vane 33 is uniformly set, so that each vane 33 can be continuously rotated due to inertia after the suction airflow is removed, and the duration of continuous rotation can be prolonged. Since the inertia of the inertia impeller 3 is larger the longer the inertia of the inertia impeller 3 is kept rotating after the user stops sucking, and the inertia of the inertia impeller 3 is increased by increasing the thickness of the part of the blades 33 to increase the weight thereof, the time the inertia impeller 3 is kept rotating due to inertia is prolonged.

It should be noted that, the degree of the spiral twisting of the blades 33 along the axial direction of the rotating shaft 32 should be set according to practical needs, so long as each blade 33 can rotate around the rotating shaft 32 under the impact of the suction airflow, that is, when the suction airflow passes through the channel between every two adjacent blades 33, the spiral twisting portion on the blade 33 can be impacted to generate a thrust on the blade 33, so that the blade 33 can rotate around the axis of the rotating shaft 32, which is not limited herein. In addition, the location of the inertial impeller 3 in the airflow channel 12 and the specific structure of the mounting assembly 31 are similar to those of the above embodiment, and will not be described herein. In the present embodiment, it is understood that the inertia impeller 3 (shown in fig. 11) of the present embodiment is mainly different from the inertia impeller 3 of the embodiment shown in fig. 3 to 4 in that the former increases the inertia of the inertia impeller 3 by increasing the partial thickness of the blades 33 and the latter increases the inertia of the inertia impeller 3 by providing the weight 34 connected to the blades 33.

In the above embodiment of the atomizer, it should be noted that, in some specific application scenarios, the atomizer may further include a microphone (not shown), where the microphone is installed in the air inlet channel 121 and is set offset from the air outlet channel 122, the atomizing core 2 is set in the air outlet channel 122, the inertia impeller 3 is set in the air outlet channel 122 and is located directly above the atomizing core 2 or directly below the atomizing core 2, when the user stops sucking, the inertia impeller 3 blows the vapor remaining in the air outlet channel 122 out of the atomizer at the first time, so that the vapor can be effectively prevented from flowing into the air inlet channel 121, and condensate is formed in the air inlet channel 121, thereby preventing the condensate from polluting the microphone and affecting the normal use of the microphone.

Correspondingly, the embodiment of the utility model also provides an electronic atomization device (not shown), which comprises: the battery pack is electrically connected with the atomizing core 2 in the atomizer, and the battery pack is used for providing electric energy for the atomizing core 2 of the atomizer so that the atomizing core 2 can be electrified and heated and gasifies atomized liquid adsorbed by the battery pack and derived from the liquid storage bin 11 into steam fog which can be sucked by a user, wherein in some specific application scenes, the battery pack can specifically comprise a power supply and a control circuit board, the power supply can be a lithium battery or a dry battery, the control circuit board is electrically connected with the power supply and the atomizing core 2 respectively, and the power supply can be controlled by the control circuit board to supply power to the atomizing core 2, so that the atomizing core 2 is electrified and heated and gasifies atomized liquid adsorbed by the battery pack into steam fog which can be sucked by the user.

In this embodiment, specifically, the electronic atomization device of this embodiment may be an electronic cigarette (in this case, the atomized liquid mentioned in the foregoing embodiment of the present utility model may be tobacco tar), and the electronic atomization device of this embodiment has the same technical effects as the foregoing atomizer thanks to the improvement of the foregoing atomizer, and is not repeated here. Besides, because assembly gaps inevitably exist between the components of the atomizer and between the atomizer and the battery assembly, vapor mist remained in the air flow channel 12 is discharged out of the atomizer through the inertia impeller 3 to prevent the vapor mist from being retained in the air flow channel 12 to form condensate, the condensate can be prevented from flowing onto the control circuit board along the assembly gaps between the components of the atomizer and the assembly gaps between the atomizer and the battery assembly, and the control circuit board is burnt out, so that the service life of the electronic atomization device can be prolonged.

The foregoing description of the preferred embodiments of the present utility model should not be construed as limiting the scope of the utility model, but rather should be understood to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the utility model as defined by the following description and drawings or any application directly or indirectly to other relevant art(s).
