When the housing provided by the embodiment of the present application is applied to the electronic cigarette atomization device, the external air can be mixed with the smoke generated inside the electronic cigarette atomization device and enter the oral cavity of the user from the air outlet 101 through the air outlet channel 11. Because the internal wall face of air outlet channel 11 is not vertical setting, but demonstrate the slope of certain angle, when external air mixes after smog and gets into air outlet channel 11 and climb towards gas outlet 101 like this, have certain resistance of climbing, the air current can not directly rush to gas outlet 101 with very fast speed, but will climb towards gas outlet 101 with comparatively slow speed, because the speed that the air current climbed can be delayed to the inner wall of air outlet channel 11 that the slope set up, like this alright let air and smog further intensive mixing, the air mixes more evenly with smog, the suction taste is better. In addition, the inner wall of the obliquely arranged air outlet channel 11 can prevent the condensate from rising to a certain extent, and the condensate is prone to have a tendency of dripping downwards along the inner wall surface of the air outlet channel 11 in the process of climbing towards the air outlet 101, so that the probability of sucking the condensate by a user is reduced, and the suction taste is further improved.
In one embodiment, the inclination angle of the inclined arrangement is in the range of 5 ° to 15 °.

Referring to fig. 1, in an embodiment, further, the first intersection line 111 and the second intersection line 112 are symmetrically disposed obliquely with respect to the first central axis.
In this specific example, the air outlet channel 11 has a shape similar to a circular truncated cone, which is bilaterally symmetrical, and thus the air outlet channel 11 has a simple processing technology and a low manufacturing cost.
Referring to fig. 1, in an embodiment, the first intersection line 111 forms a first included angle with the first central axis, and the second intersection line 112 forms a second included angle with the first central axis, where the first included angle is different from the second included angle.
In this particular example, at the cross section where the first central axis is located, two sides of the cross section intersecting with the inner wall surface of the air outlet channel 11 are in an asymmetric inclined form, that is, the inclined angle on one side is larger, and the inclined angle on the other side is smaller, so that the condensate is prevented from climbing upwards, the suction of the user is facilitated, and the air and the smoke can be mixed more sufficiently.
Referring to fig. 1, in one embodiment, the air outlet channel 11 has a first end at the air outlet 101 and a second end far away from the air outlet 101, and the first intersection line 111 and the second intersection line 112 are arranged in a gradually approaching manner from the first end to the second end.
In this specific example, the outlet passage 11 has a shape with a larger caliber at the upper end and a smaller caliber at the lower end; i.e. the aperture at the outlet 101 is larger and the aperture at the other end remote from the outlet 101 is smaller. This helps the user to puff, avoids the user from having difficulty in puffing, and the user has a greater flow of air into the mouth when puffing at the air outlet 101 and a better mouth feel in puffing.

The application embodiment provides an electron smog apparatus's theory of operation does: the tobacco tar stored in the electronic cigarette liquid storage cavity 102 continuously permeates into the liquid absorption surface of the porous body 31, and the liquid absorption surface absorbs the tobacco tar and conducts the tobacco tar to the atomization surface; when the user used this electron smog spinning disk atomiser suction, inside sensor was triggered to signals orders about the heat-generating body subassembly that sets up on the atomizing surface and heats the tobacco tar and produces aerosol, and the tobacco tar is heated atomizing in atomizing chamber 20, and external air current gets into via the inlet channel 21 of lower cover 2, takes away the smog in atomizing chamber 20, passes through outlet channel 11 in the shell body 1 again, finally enters into the user oral cavity from gas outlet 101.
In the electronic smoking device provided by the embodiment of the application, firstly, as mentioned above, the air and the smoke can be further mixed sufficiently, the probability of the user sucking the condensate can be reduced to a certain extent, and the smoking taste is improved.
Secondly, in the electron smog apparatus in this application embodiment, only adopt shell body 1 and 2 complex forms of lower cover to carry on spacingly to structures such as atomizing core 3 and atomizing core sealing member 4, cancelled upper bracket, upper bracket sealing washer and lower carriage among the traditional structure, simplified the inside structure of electron smog apparatus greatly to practice thrift part manufacturing cost and assembly cost, improved production efficiency. In addition, the structure of the electronic atomization device leaves more space for the liquid storage cavity 102 and the atomization cavity 20, and in the electronic atomization device, the volume of the liquid storage cavity 102 for storing the tobacco tar and the space formed by the smoke, namely the volume of the atomization cavity 20 can be larger than the prior art. In addition, among the prior art, be provided with the upper bracket between atomizing core subassembly and shells inner wall, and in the electron smog apparatus that this application embodiment provided, atomizing core subassembly directly hugs closely shell body 1's inner wall, consequently can do the volume of atomizing core 3 in the atomizing core subassembly bigger, and the tobacco tar is bigger from the area of imbibition face to the atomizing face, when the user suction, the oil seepage volume increase to the smog volume increase, the taste of suction is better.
Referring to fig. 2, in one embodiment, the porous body 31 has a first central axis coaxial with the air outlet 101, and the through-hole 311 has a second central axis offset to one side of the porous body 31 by a predetermined distance with respect to the first central axis; further, the atomizing surface has a first side region and a second side region on both sides of the through-hole 311 in a direction in which the second center axis is offset with respect to the first center axis, the first side region having an area larger than that of the second side region, and the heat-generating body assembly is disposed in the first side region. For example, referring to fig. 1, taking the porous body 31 as an elliptic cylinder and the through hole 311 as an elliptic hole as an example, with the long ellipse axis of the first through hole 311 as a reference, in the orientation shown in fig. 1, the region below the long ellipse axis of the first through hole 311 is the first side region, and the region above the long ellipse axis of the first through hole 311 is the second side region.
In this specific example, referring to fig. 2, taking the porous body 31 as an elliptic cylinder and the through hole 311 as an elliptic hole as an example, the first through hole 311 is offset towards one side on the porous body 31 along the direction of the minor axis of the ellipse, and the heating element assembly is offset towards the other side on the atomization surface along the direction of the minor axis of the ellipse, that is, the heating element assembly is arranged on one side relative to the through hole 311, so that the heating efficiency of the heating element assembly can be improved, the atomization surface generates heat stably and efficiently, and the atomization effect of the atomization surface is improved; and the hole edge width of the porous body 31 on the side of the heat-generating body assembly can be designed to be maximized, thereby improving the strength of the atomizing core 3. Further specifically, the through hole 311 is arranged spaced apart from the heat-generating body assembly.
Referring to fig. 2, in an embodiment, further, along a direction in which the second central axis is offset from the first central axis, the porous body 31 has a first radial dimension, and the predetermined distance is 1/5-1/3 of the first radial dimension.
If the distance by which the through-holes 311 are offset with respect to the porous body 31 is too large, it is easy to cause the width of the side of the through-holes 311 to be too small, and the strength of the porous body 31 on this side is low, thereby affecting the overall strength quality of the porous body 31; if the distance by which the through-holes 311 are offset with respect to the porous body 31 is excessively small, the function of improving the air flow path of the air flow is not performed well. Therefore, in the present embodiment, the predetermined distance by which the through-holes 311 are offset is set to 1/5-1/3 of the first radial dimension, without affecting the strength of the porous body 31 while ensuring improved airflow.
Referring to fig. 2, in one embodiment, the porous body 31 is an elliptical cylinder, the through hole 311 is an elliptical hole, the elliptical minor axis of the atomization surface coincides with the elliptical minor axis of the through hole 311, and the elliptical major axis of the atomization surface is offset from the elliptical major axis of the through hole 311 by the predetermined distance.
Because the cross-sectional shape of the electronic cigarette shell is mostly elliptical, the porous body 31 is arranged as an elliptical cylinder, and the shape of the porous body 31 is matched with that of the shell body 1, so that the porous body 31 can be better attached to the inner wall of the shell body 1 during assembly; moreover, the volume of the porous body 31 can be maximized under the condition of being matched with the shell body 1, so that the liquid matrix in the liquid storage cavity of the electronic cigarette can more smoothly permeate from the liquid absorption surface to the atomization surface of the porous body 31, the atomization efficiency of the porous body 31 is further improved, and the smoking taste of a user is better. Moreover, the elliptical through-holes 311 are opened in the elliptical porous body 31, which contributes to designing the width of the porous body 31 at the edge thereof. Further, the through-hole 311 is provided so as to be offset with respect to the porous body 31 in the direction of the minor axis of the ellipse, which is advantageous in arranging the heat generating body assembly having a long length.
Referring to fig. 3-4, in one embodiment, the electronic cigarette atomizing device further comprises an atomizing core sealing member 4, wherein the atomizing core sealing member 4 is sleeved on the outer side of the porous body 31; the atomizing cartridge seal 4 is configured for forming a mutual pressing sealing fit with the inner wall of the housing body 1.
Further specifically, the porous body 31, the atomizing core sealing member 4 and the housing body 1 enclose to form the liquid storage chamber 102; the atomizing cavity 20 is formed by enclosing the porous body 31, the atomizing core sealing piece 4, the shell body 1 and the lower cover 2. Atomizing core sealing member 4 can improve the sealing performance between atomizing core subassembly and the inner wall of shell body 1, prevents unnecessary switching on, effectively avoids the emergence of oil leak.
Referring to fig. 2, in one embodiment, a ventilation through groove 301 is formed in a side portion of the porous body 31, and the atomizing core seal 4 and the ventilation through groove 301 enclose a ventilation channel, which penetrates from the atomizing surface to the liquid suction surface.
In this specific example, when the tobacco tar permeates to the atomizing surface from the liquid absorbing surface through the porous body 31 of the atomizing core 3, the air pressure in the liquid storage cavity 102 is reduced, and simultaneously the air enters the atomizing cavity 20 from the air inlet channel 21, the air pressure in the atomizing cavity 20 is greater than the air pressure in the liquid storage cavity 102 at this time, the air enters the liquid storage cavity 102 from the atomizing cavity 20 through the air exchange channel formed by the air exchange through groove 301 and the atomizing core sealing member 4, so that the air pressure balance of the liquid storage cavity 102 and the atomizing cavity 20 is effectively realized, the occurrence of the situation that the tobacco tar is difficult to smoothly permeate to the atomizing surface from the liquid absorbing surface of the porous body 31 is avoided, and the dry burning is prevented from occurring to influence the taste of the user during smoking. In this embodiment, the tobacco tar in the liquid storage chamber 102 can smoothly permeate from the liquid absorption surface of the porous body 31 to the atomization surface, the atomization effect of the atomization surface is good, and the user has good smoking taste. Further, when the air pressure in the atomizing chamber 20 is greater than the air pressure in the reservoir chamber 102, the atomizing core sealing member 4 is pushed open under the action of the air pressure in the atomizing chamber 20, so that the air can enter the reservoir chamber 102 from the atomizing chamber 20 through the ventilation through groove 301; when the air pressures in the reservoir 102 and the aerosolization chamber 20 are balanced, the atomizing core seal 4 falls back to cover the air-venting channel 301, preventing the liquid substrate in the reservoir 102 from flowing into the aerosolization chamber 20. The cooperation of the atomizing core 3 and the atomizing core sealing member 4 can realize ventilation and sealing of the liquid storage cavity 102 and the atomizing cavity 20 when the user uses the atomizing cavity.

In this particular example, the provision of at least two venting channels 301 may better maintain the air pressure balance between the reservoir chamber and the aerosolizing chamber.
Referring to fig. 2, in one embodiment, at least two ventilation slots 301 are uniformly distributed.
When a plurality of ventilation through grooves 301 are arranged, the ventilation through grooves 301 may be symmetrically and uniformly arranged or non-uniformly arranged; in this specific example, the at least two ventilation through grooves 301 are uniformly distributed, so that the airflow is more balanced, and the air pressure balance effect between the liquid storage cavity and the atomization cavity is improved. The plurality of ventilation grooves 301 may be formed in the same shape or different shapes. The uniform distribution means that the ventilation grooves 301 are arranged in a centrosymmetric manner with respect to the center of the porous body 31.
Referring to fig. 3 and 4, in one embodiment, a protrusion 401 is further disposed on the atomizing core seal 4, and the protrusion 401 covers the ventilation through-slot 301.
Further, the protrusion 401 covers one end of the ventilation through groove 301 close to the liquid storage cavity 102. The projection 401 is arranged on the atomizing core sealing piece 4 and corresponds to the ventilation through groove 301, when the air pressure between the liquid storage cavity and the atomizing cavity is balanced, the projection 401 covers one end of the ventilation through groove 301 close to the liquid storage cavity, so that a better sealing effect can be achieved, and liquid matrix in the liquid storage cavity is effectively prevented from flowing to the atomizing cavity; when atmospheric pressure is uneven, for example, when the tobacco tar permeates the atomizing face from its imbibition face through porous body 31, thereby the air pressure in stock solution chamber reduces, the air gets into the atomizing chamber from inlet channel simultaneously, the atmospheric pressure in the atomizing chamber is greater than the atmospheric pressure in stock solution intracavity this moment, atomizing core sealing member 4 is backed up under the effect of atomizing intracavity atmospheric pressure, thereby it is gaseous can be through logical groove 301 from the atomizing chamber entering stock solution chamber to take a breath, realize that atmospheric pressure is balanced, prevent the problem that the tobacco tar is down liquid not smooth and atomizing core dry combustion method from appearing.
Referring to fig. 3 and 4, in one embodiment, the outer side surface of the atomizing core seal 4 is further provided with a first elastic rib 42, and the first elastic rib 42 abuts against the inner wall of the housing body 1.
In this specific example, the first elastic rib 42 realizes interference fit between the inner wall of the housing body 1 and the porous body 31 of the atomizing core 3, so as to seal the outer wall surface of the porous body 31 and also seal the inner side wall of the housing body 1, thereby improving the sealing effect between the atomizing core sealing member 4 and the housing body 1 and preventing the oil from leaking from the liquid storage cavity of the electronic cigarette to the atomizing cavity.
Referring to fig. 3 and 4, in an embodiment, further, a tubular structure 43 matching with the through hole 311 is formed on the atomizing core sealing member 4, and the tubular structure 43 is inserted into the through hole 311.

The matching structure of the sealing edge 431 and the step surface 110 can play a good role in sealing, and prevent liquid from passing through the gap between the air outlet channel 11 and the porous body 31 and further leaking into the through hole 311, the atomizing chamber 20 and the air outlet channel 11. The sealing rim 431 has a portion disposed around the edge of the suction surface and a portion disposed around the circumference of the through hole 311. The portion of the sealing rim surrounding the through hole 311 forms a seal between the step face 110 and the liquid-absorbing face. Specifically, the sealing rim 431 provides a sealing action between the liquid suction surface portion outside the orifice of the through-hole 311 and the step surface 110.
