It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

Referring to fig. 2-8, according to one embodiment of the present application, an electronic aerosolization device is provided. The electronic cigarette atomization device comprises a shell 1 and a lower cover 9, wherein one end of the shell 1 is provided with a suction inlet 11, and the other end of the shell is an opening end; the lower cover 9 is arranged at the opening end of the shell 1 in a covering manner; the lower cover 9 is provided with an air inlet channel communicated with the outside atmosphere, the air inlet channel comprises a first air inlet channel 91 and a second air inlet channel 92 which are communicated with each other, and the first air inlet channel 91 and the second air inlet channel 92 are sequentially arranged from the direction far away from the suction port 11 to the direction close to the suction port; the cross-sectional area of the first air intake passage 91 is larger than the cross-sectional area of the second air intake passage 92; the second air intake passage 92 includes a plurality of branch passages, which communicate with each other.

Referring to fig. 1, which is a schematic structural view of a lower cover 01 of an electronic cigarette in the prior art, an air inlet channel a011 and an air inlet channel b012 are sequentially opened at the bottom of the lower cover 01 from bottom to top; the cross-sectional area of the intake passage a011 is larger, the cross-sectional area of the intake passage b012 is smaller, two intake passages b012 are opened, the two intake passages b012 are arranged at intervals along the radial direction, and a retaining wall 013 is arranged between the two intake passages b 012. When a user sucks the electronic cigarette, air enters through the air inlet channel a011, is shunted to enter the electronic cigarette at the two air inlet channels b012, carries away aerosol in the electronic cigarette, enters the air outlet channel and finally reaches the oral cavity of the user. When air enters the two air inlet channels b012 from the air inlet channel a011 to be divided, due to the obstruction of the retaining wall 013, part of the air flow can enter the two air inlet channels b012 only after bypassing the wall surface of the retaining wall 013, and the part of the air flow collides with the air flow directly flowing into the two air inlet channels b012 and is merged, so that a large vortex is generated at the position, and strong collision vibration is generated with the surrounding wall surface of the vortex, and a large sound is generated. Meanwhile, the air inlet channel a011 is a complete cylindrical structure with a larger cross section area, the air inlet channel b012 is two cylindrical structures with a smaller cross section area which are separated and independent from each other, and the difference between the cross section areas of the air inlet channel a011 and the air inlet channel b012 is larger; when the airflow flows into the small-area air inlet channel b012 from the large-area air inlet channel a011, the airflow speed is accelerated in the air inlet channel b012 more due to the increase of the air pressure, and the airflow collides with the lower bracket air inlet end face of the electronic cigarette at a faster speed, so that the airflow generates larger vibration, louder noise is generated, and the use experience of a user is influenced.

Referring to fig. 3 to 6, in the electronic fuming apparatus provided in the embodiment of the present application, the second air intake passage 92 communicating with the first air intake passage 91 is designed to include a plurality of branch passages in the lower cover 9, and the plurality of branch passages communicate with each other. The structure of the baffle wall is cancelled in the second air inlet channel 92, when the air flow flows into the second air inlet channel 92 from the first air inlet channel 91, the air flow directly flows into the branch channels which are communicated with each other, and the air flow cannot be blocked by too many structures, so that the flowing track of the air flow cannot be obviously changed, the air flow can flow at a moderate flow speed, the collision vibration is reduced, and the noise is reduced. And, because second inlet channel 92 includes a plurality of branch passageways that communicate each other, when the air current flows in second inlet channel 92, a plurality of branch passageways that communicate each other can cushion the air current, postpone the velocity of flow of air current, when the air current enters into this electron smog spinning disk atomiser's inner structure through lower cover 9, can alleviate the impact vibration of air current to inner structure to further reach the effect of noise reduction. In addition, since the second air intake passage 92 of the electronic atomizing device provided in the embodiment of the present application includes only a plurality of branch passages communicating with each other without including a retaining wall structure, in the case that the cross-sectional area of the first air intake passage 91 is the same, the electronic atomizing device provided in the present application can make the cross-sectional area of the second air intake passage 92 larger than that of the prior art, so that the difference between the cross-sectional area of the first air intake passage 91 and the cross-sectional area of the second air intake passage 92 is reduced as compared with that of the prior art, and therefore, when the air flow flows into the second air intake passage 92 from the first air intake passage 91, the increase in the pressure of the air is not too significant, the flow speed of the air in the second air intake passage 92 is not increased too much, and therefore, the air flow enters the inside of the electronic atomizing device at a relatively gentle flow speed, and the vibration generated by the air flow is not too significant, thereby achieving the effect of reducing noise.

Referring to fig. 4, in one embodiment, the branch passages include a central passage 921 and at least two edge passages 922 disposed around the central passage 921, each of the edge passages 922 communicating with the central passage 921.

In this particular example, the branch channels specifically include a central channel 921 and a plurality of edge channels 922 disposed around the central channel 921, and each edge channel 922 communicates with the central channel 921. Such an arrangement is convenient for communicating the plurality of branch passages, and the second air intake passage 92 is relatively simple to open and convenient to operate.

Referring to fig. 4, in one embodiment, further, the second air inlet passage 92 includes four edge passages 922, and the four edge passages 922 are evenly distributed around the central passage 921.

In this specific example, the second air intake passage 92 is composed of a center passage 921 and four edge passages 922 arranged in communication around the center passage 921, the four edge passages 922 being arranged in a cross shape at the cross section of the second air intake passage 92; that is, the four edge channels 922 are symmetrically and uniformly distributed around the central channel 921, and when the air flow flows from the first air inlet channel 91 to the second air inlet channel 92, the air flow is more uniformly dispersed into the central channel 921 and the four edge channels 922, which can provide a good buffering effect for the air flow.

In one embodiment, further, the second air intake passage 92 includes six edge passages 922, and the six edge passages 922 are evenly distributed around the central passage 921.

In this particular example, at the cross section of the second air intake passage 92, the six edge passages 922 exhibit a structure similar to the "+" shape, so that when the air flow flows from the first air intake passage 91 into the second air intake passage 92, the air flow is dispersed more into the passages, and therefore this embodiment also provides a good buffering action for the air flow.

In one embodiment, further, the second air intake passage 92 includes eight edge passages 922, and the eight edge passages 922 are evenly distributed around the central passage 921.

In this particular example, at the cross section of the second air intake passage 92, the edge passage 922 can be seen as including two sets of criss-cross passages, which present a "cross" configuration, so that when the air flow flows from the first air intake passage 91 into the second air intake passage 92, the air flow is dispersed into more passages, and thus this embodiment also provides a good buffering effect for the air flow.

In one embodiment, further, the width of the edge channel 922 at the cross section of the second air inlet channel 92 is 0.2mm to 1 mm.

In this particular example, the width of the edge channels 922 is set to 0.2mm to 1mm, and the width of different edge channels 922 may be the same or different. The size of the central passage 921 can be effectively reduced by the arrangement of the edge passage 922 in the size range, so that the width of the air inlet passage is reduced under the condition that the same air inlet area of the second air inlet passage 92 is ensured, and the liquid is prevented from flowing out of the air inlet passage, so that the liquid can better flow into the space where the oil absorption element is arranged in the lower cover 9 along the shell 1. Also, the edge passage 922 in this width range may satisfy that the cross-sectional area of the second intake passage 92 does not have an excessively large difference from the cross-sectional area of the first intake passage 91; and the edge channel 922 within this width conforms to the size limitations of the slot provided in the lower cover 9 of the electronic cigarette aerosolization device.

Referring to fig. 7 to 8, the electronic cigarette atomizing device provided in the embodiments of the present application operates according to the following principle: the liquid substrate stored in the liquid storage cavity 12 continuously permeates into the liquid suction surface of the aerosol generating body 5 through the liquid injection through hole 31 of the upper bracket 3, and the liquid suction surface of the aerosol generating body 5 absorbs the liquid substrate so as to heat the liquid substrate to generate aerosol; when a user uses the electronic cigarette atomizing device for suction, the internal sensor is triggered to send a signal to drive the aerosol generating body 5 to start heating, the liquid substrate is heated and atomized in the aerosol generating cavity B, the external air flow enters through the air inlet channel A of the lower cover 9 to take away the smoke in the aerosol generating cavity B, and then sequentially passes through the air outlet through hole 32 of the upper bracket 3 and the air outlet channel 13 in the shell 1 to enter the oral cavity of the user from the suction inlet 11. In the electronic atomization device provided by the embodiment of the application, because the air inlet channel a in the lower cover 9 does not contain a retaining wall structure, the air flow is not blocked by too many structures when entering, and the flowing track of the air flow is not obviously changed, so the air flow can flow at a milder flow speed; and the difference between the cross-sectional area of the first intake passage 91 and the cross-sectional area of the second intake passage 92 constituting the intake passage a is not large, when the gas flows from the first intake passage 91 into the second intake passage 92, the increase in the gas pressure is not so significant, and the flow velocity of the gas in the second intake passage 92 is not so much accelerated; meanwhile, the second air inlet passage 92 comprises a plurality of mutually communicated branch passages which can buffer the air flow and delay the flow rate of the air flow; therefore, when a user sucks, the airflow enters the electronic cigarette atomizing device at a relatively flat flow rate, and the generated vibration is not too obvious, so that the effect of reducing noise is achieved.

In this particular example, the gas-liquid balance tank 33 may be disposed to facilitate ventilation to supplement the pressure in the reservoir 12, and the gas-liquid balance tank 33 may slow down the flow rate of the liquid substrate flowing out of the reservoir 12, so that the external gas may smoothly enter the reservoir 12 from a side away from the reservoir 12.
