Referring to fig. 3 and 6 in combination, the atomizing assembly 1 provided by the present application includes a base 11, a heating element 30 and a gas-homogenizing sheet 40, the base 11 has an atomizing chamber 101 and a plurality of gas flow channels 304 (shown in fig. 10 and 11) that are communicated with each other, the atomizing chamber 101 is used for accommodating an aerosol-generating substrate, and the plurality of gas flow channels 304 are used for guiding gas into the atomizing chamber 101. The heating member 30 is disposed in the gas flow passage 304 for heating the gas flowing through the gas flow passage 304. The gas homogenizing plate 40 is disposed at a communication position between the atomizing chamber 101 and the gas flow channel 304, and a plurality of first through holes 401 (as shown in fig. 13) are disposed on the gas homogenizing plate 40, so that the gas flow of the gas flow channel 304 enters the atomizing chamber 101 through the plurality of first through holes 401. Wherein, a plurality of first through-holes 401 encircle the central point O distribution of the air inlet of atomizing chamber 101 to form a plurality of concentric rings of interval setting, from innermost ring to outermost ring, the distribution density of first through-hole 401 increases gradually. The central region B of each gas flow channel 304 is disposed corresponding to a spaced position between two adjacent ones of the plurality of concentric rings.
It can be understood that, by arranging the gas-homogenizing plate 40 between the atomizing cavity 101 and the gas flow passage 304, the plurality of first through holes 401 distributed around the central point O of the gas inlet of the atomizing cavity 101 are arranged on the gas-homogenizing plate 40, and the gas flowing through the gas flow passage 304 and about to enter the atomizing cavity 101 is dispersed and balanced by the plurality of first through holes 401, so that the gas can uniformly enter the atomizing cavity 101. Wherein, a plurality of concentric rings that the interval set up are formed in a plurality of first through-holes 401 distribution on gas homogenizing sheet 40, and from innermost ring to outermost ring, the distribution density of first through-holes 401 on each ring increases gradually, namely, from innermost ring to outermost ring, the quantity of first through-holes 401 in the unit area on each ring increases gradually. By increasing the distribution density of the first through holes 401 at the peripheral position of the gas-homogenizing sheet 40, the gas distribution amount at the peripheral position when the gas flow enters the atomizing chamber 101 from the gas flow channel 304 can be effectively increased, and the problem that the gas flow is concentrated at the central position of the atomizing chamber 101 and the gas distribution at the peripheral position is less when the gas flow enters the atomizing chamber 101, which affects the uniformity of heated atomization of the aerosol generating substrate in the prior art is solved.
More importantly, the substrate 11 includes a plurality of airflow channels 304, the airflow volume can be increased by the plurality of airflow channels 304, and the central area B of each airflow channel 304 is arranged corresponding to the interval position between two adjacent rings of the plurality of concentric rings, that is, the first through hole 401 is not arranged at the position corresponding to the central area B of the airflow channel 304, the first through hole 401 is arranged to avoid the central area B of the plurality of airflow channels 304, so that the problem that the airflow volume of the gas flowing through the airflow channel 304 directly enters the atomizing chamber 101 through the first through hole 401 arranged opposite to the first through hole 304, but the problem that the airflow volume of the rest of the first through holes 401 arranged corresponding to the airflow channel 304 is insufficient can be avoided, the problem that the airflow volume of the airflow channel 304 in the atomizing chamber 101 is large and the airflow volume of the rest positions is small, which causes uneven heating and atomization of the aerosol-generating substrate in the atomizing chamber 101, the uniformity of the airflow distribution at each position when the airflow enters the atomizing chamber 101 through the airflow channel 304 is effectively improved, and the atomization performance of the atomization assembly 1 is improved.
Specifically, the base body 11 includes an atomizing body 10 and a current carrier 20. Referring to fig. 3, the fixing base 12 is disposed at the periphery of the atomizing body 10 and abuts against the support 22 for fixing the atomizing body 10. Specifically, the fixing base 12 has an accommodating cavity (not shown), the bottom wall of the accommodating cavity has an opening (not shown), the atomizing body 10 is disposed in the accommodating cavity and spaced from the sidewall of the accommodating cavity, and one end of the atomizing body 10, which is far away from the flow guiding body 20, extends from the opening and is limited by the opening. The side wall of the accommodating cavity is provided with an annular flange which is abutted with the side wall of the shell 3. The holder 12 fixes the atomizing body 10 and minimizes heat absorption into the atomizing body 10. The material of the fixing base 12 may be plastic, silicon, etc., which is not limited in this application. One side of the fixing base 12 close to the cover 4 is provided with a magnetic component (not shown), the cover 4 includes a magnetic component or is made of metal, and the magnetic component attracts the fixing base 12 and the cover 4 together, so that when the electronic atomization device 100 is used, the cover 4 and the atomization assembly 1 are kept relatively still.
The atomizing body 10 and the flow guiding body 20 of the base body 11 may be two independent parts which are detachably connected, or may be an integrally formed structure. When the atomizing body 10 and the current carrier body 20 are detachable structures, the manufacturing and cleaning are convenient, but in this case, a first sealing member 60 is required to be arranged at the joint of the current carrier body 10 and the current carrier body 10 for sealing, so as to prevent the gas from leaking from the side surfaces of the current carrier body 20 and the atomizing body 10, and causing heat loss. As shown in fig. 6, the first sealing element 60 is disposed on a contact surface between the atomizing body 10 and the flow guiding body 20, and is used to seal a joint between the atomizing body 10 and the flow guiding body 20, and the first sealing element 60 may be made of silica gel, rubber, or other materials, and is specifically selected as needed as long as the purpose of sealing can be achieved. When the atomizing body 10 and the flow guiding body 20 are integrally formed, the sealing performance is good, the aerosol generating substrate cannot leak and overflow and be wasted, but the requirement on a mold in the manufacturing process is high. Therefore, in practice, two structures can be selected according to needs, and the application does not limit the structures.
The materials of the atomizing body 10 and the current carrier 20 are not limited and may be selected as desired. Specifically, the atomizing body 10 and the flow guiding body 20 of the base body 11 are ceramic bodies and made of the same material. The ceramic material can be a low-heat-conductivity ceramic body, and the low-heat-conductivity ceramic body has high temperature resistance, very low heat conductivity and excellent heat insulation performance, and can be applied to environments with higher temperature. The ceramic body may be a single material or a combination of two or more different materials. In addition, other materials with low thermal conductivity and high temperature resistance can be adopted, and the application does not limit the materials.
The atomizing body 10 has an atomizing chamber 101, the current carrier 20 is provided with a plurality of air flow channels 304, and the gas-equalizing sheet 40 is disposed between the atomizing body 10 and the current carrier 20 and communicates the atomizing chamber 101 and the plurality of air flow channels 304.
Specifically, referring to fig. 6 to 9, the atomizing body 10 has a first surface 102 and a second surface 103 opposite to each other, where the first surface 102 is a surface of the atomizing body 10 near an end of the cover 4, and the second surface 103 is a surface of the atomizing body 10 near an end of the current carrier 20. The first surface 102 has a first recess 104, the first recess 104 serving as an atomizing chamber 101 of the substrate 11 for storing and atomizing an aerosol-generating substrate to form an aerosol. The shape, size, and number of the first grooves 104 may be set as needed, and for example, the first grooves 104 may have any shape such as a truncated cone shape, a cylindrical shape, an elliptical cylinder shape, a prism shape, and a pyramid shape. In this embodiment, the cross-sectional area of the first groove 104 gradually decreases from the end far away from the baffle 20 to the end near the baffle 20, for example, the first groove 104 is rectangular frustum pyramid shaped, the cross-section of the first groove 104 is rectangular, and the longitudinal section is inverted trapezoid (as shown in fig. 6). The second surface 103 has a second groove 105 communicating with the bottom of the first groove 104, i.e. the air inlet of the atomizing chamber 101, the air-equalizing sheet 40 is disposed in the second groove 105, and one end of the flow guiding body 20 close to the atomizing body 10 is inserted into the second groove 105 and clamps the air-equalizing sheet 40 with the bottom wall of the second groove 105. The size of the end of the flow guiding body 20 close to the atomizing body 10 is adapted to the size of the second groove 105 so as to facilitate clamping.
Flow conductor 20 has a plurality of flow channels 304, flow channels 304 have an inlet end 3041 and an outlet end 3042 (shown in fig. 12), outlet end 3042 of flow channels 304 is in fluid communication with first recess 104 via gas homogenizing sheet 40, and inlet end 3041 of flow channels 304 may extend to the surface or side of one end of flow conductor 20 away from aerosol 10. In some embodiments, the flow conductor 20 is bottom-side fed, and the flow channel 304 is a through-hole extending from a side surface of the flow conductor 20 near the atomizing body 10 to a side surface of the flow conductor 20 away from the atomizing body 10. The air outlet end 3042 is in fluid communication with the gas homogenizer 40 such that an air flow entering from the air inlet end 3041 passes through the air flow channel 304, and then from the air outlet end 3042 is directed to the gas homogenizer 40 and into the nebulizing chamber 101 via the gas homogenizer 40, heating the aerosol-generating substrate to produce an aerosol. In other embodiments, the flow conductor 20 may also adopt a side air intake structure, that is, air is taken from the side wall of the flow conductor 20, and the aerosol-generating substrate in the atomizing chamber 101 may also be atomized, and specifically, the air intake mode may be selected according to the requirement, which is not limited in this application.
Alternatively, the flow conductor 20 may be a cylinder, a prism, or any other structure.
Referring to fig. 10 to 12, the current carrier 20 is a cylinder and has a plurality of air guide through holes 201, and the plurality of air guide through holes 201 are uniformly arranged around a central axis of the current carrier 20. The air guide through holes 201 are straight-through holes penetrating through the surface of one side of the flow conductor 20 close to the atomizing body 10 and the surface of one side of the flow conductor 20 far from the atomizing body 10, and each air guide through hole 201 can be used as an air flow channel 304 for guiding air flow to the atomizing chamber 101. The air guide through hole 201 is a straight hole, so that the air flow path of the air flow channel 304 can be shortened, and the atomization efficiency can be improved. After entering the electronic atomization device 100, the outside air enters the air guide through hole 201 from the air inlet end 3041 of the air guide through hole 201, flows through the air guide through hole 201, is heated by the heating element 30 arranged in the air guide through hole 201, flows out from the air outlet end 3042 of the air guide through hole 201, then enters the atomization chamber 101 through the air equalizing sheet 40, and is heated and atomized for the aerosol-generating substrate in the atomization chamber 101. It can be understood that the plurality of heating members 30 are disposed in the plurality of air flow channels 304 for heating, so that the heat quantity entering the atomizing chamber 101 can be increased, the effective air outlet area and the heat exchange area between the heating members 30 and the air can be increased, and the atomizing effect can be improved. The porous heating can also improve the uniformity of heating, and prevent the conditions that the local temperature of the atomizing cavity 101 is too high and other positions are not heated in place.
As shown in fig. 10, in the present embodiment, flow guide body 20 is provided with four air guide through holes 201. In other embodiments, the air guide through holes 201 may be provided in other numbers; the air guide through holes 201 may also be inclined through holes extending from the outer side wall of the flow guide body 20 to the side surface of the flow guide body 20 close to the atomizing body 10, and may be designed as needed.
Referring to fig. 3, an end of the current carrier 20 remote from the atomizing body 10 is provided with a second sealing member 70, and the second sealing member 70 is used for sealing a connection gap between the current carrier 20 and the support 22. Specifically, the second sealing element 70 has a groove (not shown), and the structure of the groove is adapted to the structure of the flow guiding body 20 close to the second sealing element 70, so that the flow guiding body 20 can be clamped in the groove of the second sealing element 70, so as to implement the sealing function of the second sealing element 70 on the flow guiding body 20, in this embodiment, the flow guiding body 20 is cylindrical (as shown in fig. 10), and the groove of the second sealing element 70 is arranged in a circular shape corresponding to the flow guiding body 20. A through hole (not shown) is provided in the bottom wall of the recess so that the lead 302 of the heating element 30 can pass through the through hole to connect the power module 2 while ensuring that the outside air flows through the through hole into the air flow passage 304.
Referring to fig. 3, fig. 11 and fig. 12, an air inlet sheet (not shown) may be further disposed at an end of the flow guiding body 20 away from the atomizing body 10. Specifically, the end face of one end of the flow guiding body 20, which is far away from the atomizing body 10, is provided with a mounting groove 202, and the mounting groove 202 is used for mounting an air inlet sheet. In one embodiment, the mounting groove 202 is provided in a circular shape corresponding to the shape of the intake sheet. Alternatively, the air inlet plate may be fixed to the end surface of the flow guiding body 20 away from the atomizing body 10 by means of clamping, screwing, or the like, or may be integrally formed with the flow guiding body 20. The mounting groove 202 and the air inlet sheet may be correspondingly configured in other shapes. The air inlet plate has a plurality of through holes (not shown) which are uniformly distributed, so that the external air can be uniformly distributed into the plurality of air flow channels 304.
Referring to fig. 13 to 16, fig. 13 is a schematic structural view of a first embodiment of a gas-homogenizing plate of the atomizing assembly provided in fig. 6, fig. 14 is a schematic structural view of a second embodiment of the gas-homogenizing plate of the atomizing assembly provided in fig. 6, fig. 15 is a schematic structural view of a third embodiment of the gas-homogenizing plate of the atomizing assembly provided in fig. 6, and fig. 16 is a schematic structural view of a fourth embodiment of the gas-homogenizing plate of the atomizing assembly provided in fig. 6.
Referring to fig. 6, the gas-homogenizing plate 40 is disposed between the atomizing body 10 and the flow guiding body 20 and is communicated with the atomizing cavity 101 and the gas flow channel 304, and the thickness of the gas-homogenizing plate 40 is 0.1mm-0.3mm. Specifically, the gas homogenizing plate 40 is provided with a plurality of first through holes 401, the plurality of first through holes 401 are distributed around the central point O of the air inlet of the atomizing cavity 101, and a plurality of concentric rings arranged at intervals are formed on the gas homogenizing plate 40. The position distribution that a plurality of concentric rings correspond to the air inlet of atomizing chamber 101, and the shape of a plurality of concentric rings is the same with the shape of the air inlet of atomizing chamber 101, can guarantee that all positions of the air inlet of atomizing chamber 101 have the air current to pass through. The air inlet of the atomizing cavity 101 can be in any shape such as a circle, an ellipse, a rectangle and a square, and a plurality of concentric rings can also be set to any shape corresponding to the air inlet of the atomizing cavity 101, and can be designed according to specific needs, and the application does not limit the air inlet.
In the concentric rings, from the innermost ring to the outermost ring, the distribution density of the first through holes 401 on each ring is gradually increased, that is, in the direction from the center position of the air inlet of the atomizing chamber 101 to the peripheral position, the number of the first through holes 401 per unit area is gradually increased, so as to enhance the air flow rate at the peripheral position far from the position of the air outlet end 3042 of the air flow channel 304, ensure that the air flow flowing through the air flow channel 304 can be uniformly distributed at each position corresponding to the air inlet of the atomizing chamber 101 on the air distributing plate 40, improve the uniformity of air flow distribution, and avoid the problem that the air flow is concentrated at the center position or the position corresponding to the air outlet end 3042 of the air flow channel 304, and the air flow distribution is insufficient at the peripheral position far from the air outlet end 3042 of the air flow channel 304. The first through holes 401 have an aperture of 0.2mm to 0.6mm, which ensures that the aerosol-generating substrate in the nebulization chamber 101 does not fall out of the first through holes 401 during heated nebulization while the airflow is well circulated.
A central region B of the air outlet 3042 of each air flow channel 304 is disposed corresponding to a spaced position between any two adjacent rings of the plurality of concentric rings, and the first through hole 401 is not disposed at a position corresponding to the central region B of the air outlet 3042 of the air flow channel 304, that is, the first through hole 401 is disposed to avoid the central region B of the air outlet 3042 of the air flow channel 304, so that the air flow flowing through the air flow channel 304 directly passes through the first through hole 401 disposed corresponding to the central region B of the air outlet 3042 and enters the atomizing chamber 101, which results in almost no air flow passing through the first through hole 401 at other positions, the hot air flow in the atomizing chamber 101 is unevenly distributed, heat is concentrated at a position corresponding to the air outlet 3042 of the air flow channel 304, and the aerosol generating substrate is unevenly atomized. The air outlet ends 3042 of the air flow channels 304 may also be completely disposed corresponding to the spacing position between two adjacent rings of the plurality of concentric rings, the air outlet ends 3042 of the air flow channels 304 may be located between two adjacent rings, the first through holes 401 are completely disposed away from the air outlet ends 3042 of the air flow channels 304, and the air flow passing through the air flow channels 304 may also be more uniformly distributed.
In an embodiment, as shown in fig. 13, the gas equalizing sheet 40 is further provided with a second through hole 402, and the second through hole 402 is disposed corresponding to the center point O of the air inlet of the atomizing chamber 101. That is, the plurality of first through holes 401 are arranged around the second through hole 402, and the second through hole 402 is located substantially at the center of the space between the plurality of airflow passages 304. The aperture of the second through hole 402 is larger than that of the first through hole 401. It can be understood that, because the plurality of air flow channels 304 are located between two adjacent rings of the plurality of concentric rings, and the plurality of concentric rings are disposed around the central point O of the air inlet of the atomizing chamber 101, so that the distance between the position corresponding to the central point O of the air inlet of the atomizing chamber 101 on the air-distributing plate 40 and the plurality of air flow channels 304 is relatively far, the position corresponding to the central point O of the atomizing chamber 101 is provided with one second through hole 402, which can prevent no air flow from passing through the position corresponding to the central point O of the atomizing chamber 101, and the aperture of the second through hole 402 is larger than that of the first through hole 401, and can also prevent most of air flow from passing through the first through holes 401 on two adjacent rings closer to the air flow channels 304, which can improve the air flow passing through the second through hole 402, so that the air flow distribution is more uniform.
In an embodiment, as shown in fig. 14, a plurality of third through holes 403 are further disposed on the gas-distributing plate 40, the third through holes 403 are disposed corresponding to positions between the plurality of gas flow channels 304, and the diameter of the third through holes 403 is smaller than that of the first through holes 401. The third through hole 403 may be located in a space defined by the plurality of airflow channels 304, or may be located between two adjacent airflow channels 304. It can be understood that, since the plurality of air flow passages 304 are located between two adjacent rings of the plurality of concentric rings and the first through holes 401 on the two adjacent rings are located away from the central region B of the air flow passage 304, the arrangement of the air flow passage 304 makes the spacing between the two adjacent rings larger than the spacing between the other adjacent rings, and it is easy to make almost no air flow pass between the two adjacent rings at the positions other than the positions of the air flow passage 304. Set up a plurality of third through-holes 403 that the aperture is less than first through-hole 401 between a plurality of airflow channel 304, can guarantee that all the other positions between a plurality of airflow channel 304 can have the air current to pass through also not so that the air current is too big, guarantee that the air current of passing through is more even, and then guarantee to generate the matrix heating evenly to the aerosol of each position department in the atomizing chamber 101, promote the atomizing taste.
In one embodiment, as shown in fig. 15, the concentric rings have two opposite sides, and the distribution density of the first through holes 401 on one side of at least one ring is greater than that of the first through holes 401 on the other side. The aerosol generated by atomization in the atomization cavity 101 flows to the flow hole 45 on the fixing plate 43 through the atomization cavity 101, then enters the cavity 441 on the rotating shaft 44 through the flow hole 45, and finally enters the suction nozzle 41 to be sucked by a user, the flow hole 45 on the fixing plate 43 and the cavity 441 on the rotating shaft 44 are arranged offset from the central axis of the electronic atomization device 100, the flow hole 45 on the fixing plate 43 and the cavity 441 on the rotating shaft 44 are located on the same side of the central axis, and the aerosol in the atomization cavity 101 flows towards the side where the flow hole 45 is located, so as to ensure that the aerosol in the atomization cavity 101 can smoothly and sufficiently flow into the flow hole 45, the flow rate of the aerosol flowing through the first through hole 401 on the side close to the flow hole 45 on the air distribution plate is sufficient, and therefore the distribution density of the first through hole 401 on the side close to the flow hole 45 on at least one ring of the plurality of concentric rings is greater than the distribution density of the first through hole 401 on the side far from the flow hole 45, thereby achieving a better atomization effect.
Referring to fig. 6 and 16, in the present embodiment, the air inlet of the atomizing chamber 101 is rectangular, two median lines of the rectangle divide the rectangle into four sub-rectangles, and the four air guide through holes 201 of the flow guiding body 20 are disposed in one-to-one correspondence with the four sub-rectangles. The gas-homogenizing plate 40 is disposed in the second groove 105 of the atomizing body 10, and the shape of the gas-homogenizing plate 40 corresponding to the second groove 105 is a disk-shaped structure. The first through holes 401 of the gas-distributing plate 40 surround the center point O of the gas inlet of the atomizing chamber 101 to form a plurality of concentric rectangular rings, and the concentric rectangular rings are arranged corresponding to the gas inlet of the rectangular atomizing chamber 101. Specifically, the number of the rectangular rings is n, and n is a positive integer of 3 or more and 10 or less. The first rectangular ring H1, the second rectangular ring H2, the third rectangular ring 8230, the fourth rectangular ring 8230and the fifth rectangular ring Hn are arranged from the innermost ring to the outermost ring in sequence. The distribution density of the first through holes 401 on each ring gradually increases from the first rectangular ring H1 to the nth rectangular ring Hn.
Specifically, the distance between the first rectangular ring H1 and the second rectangular ring H2 is greater than the distance between the other adjacent rings, and the central regions B of the four air guide through holes 201 are arranged corresponding to the spaced positions between the first rectangular ring H1 and the second rectangular ring H2, so as to ensure that the air flow is uniformly distributed to the first through holes 401. The distribution density of the first through holes 401 on one of the two long sides of the (n-1) th rectangular ring H (n-1) is less than the distribution density of the first through holes 401 on the other long side, for example, the number of the rectangular rings is 4, and the distribution density of the first through holes 401 on the long side of the two long sides of the third rectangular ring H3 close to the circulation holes 45 on the fixing plate 43 is greater than the distribution density of the first through holes 401 on the long side far from the circulation holes 45 on the fixing plate 43 (as shown in fig. 16), so as to ensure that the air flow volume close to the circulation holes 45 is sufficient, and the aerosol generated by atomization flows to the air flow holes more smoothly.
In this embodiment, the n-th rectangular ring Hn is provided with a plurality of first through holes 401 only corresponding to the short sides of the plurality of concentric rectangular rings, and the first through holes 401 on the n-th rectangular ring Hn are arranged parallel to the short sides, that is, the long sides of the n-th rectangular ring Hn are not provided with the first through holes 401. For example, the number of the rectangular rings is 4, and the fourth rectangular ring H4 is provided with a plurality of first through holes 401 corresponding only to the short side. It can be understood that, since the shape of the air inlet of the atomizing chamber 101 is rectangular, there are long sides and short sides, and the distance between two short sides and the plurality of air flow channels 304 is farther than the distance between two long sides and the plurality of air flow channels 304, and the short side of the outermost ring is farthest from the air flow channels 304, in order to ensure the air flow at the position of the short side of the outermost ring farther from the air flow channels 304, the outermost ring is provided with the first through holes 401 only at the corresponding positions of the short sides, so as to balance the air flow at each position, and make the distribution of the air flow passing through the air-homogenizing plate 40 more uniform. The distribution density of the first through holes 401 in the nth rectangular ring Hn may be equal to the distribution density of the first through holes 401 in the (n-1) th rectangular ring H (n-1), and as shown in fig. 16, the distribution density of the first through holes 401 in the fourth rectangular ring H4 is equal to the distribution density of the first through holes 401 in the third rectangular ring H3.
As shown in fig. 16, in this embodiment, the gas-homogenizing plate 40 further includes a second through hole 402 and a plurality of third through holes 403, the second through hole 402 is disposed corresponding to the central point O of the rectangular ring, and the aperture of the second through hole 402 is larger than that of the first through hole 401, so as to ensure the gas flow at the central position of the gas-homogenizing plate 40. A plurality of third through holes 403 are provided corresponding to positions between the four air guide through holes 201, and the aperture of the third through holes 403 is smaller than that of the first through holes 401. The third through holes 403 are respectively formed with a diamond ring L and an (n + 1) th rectangular ring H (n + 1), specifically, a fifth rectangular ring H5, around the center point O of the atomizing chamber 101. Four third through holes 403 are distributed on the diamond ring L, the four third through holes 403 are respectively located on two median lines of the first rectangular ring H1, specifically, two third through holes 403 on the median line of the short side of the first rectangular ring H1 are located in the first rectangular ring H1, and two third through holes 403 on the median line of the long side are located outside the first rectangular ring H1. The (n + 1) th rectangular ring H (n + 1) is located between the first rectangular ring H1 and the second rectangular ring H2, and since the distance between the adjacent two air guide through holes 201 in the long side direction is further, the distribution density of the third through holes 403 on the short side of the (n + 1) th rectangular ring H (n + 1) is smaller than the distribution density of the third through holes 403 on the long side, specifically, as shown in fig. 16, the third through holes 403 on the fifth rectangular ring H5 are located between the adjacent two air guide through holes 201, and the distribution density of the third through holes 403 on the long side is approximately twice as large as the distribution density of the third through holes 403 on the short side. Through setting up third through-hole 403 for all there is the air current to pass through in all other positions between four air guide through-holes 201, and the air current of all places of the equal gas piece 40 of flowing through is more even, and the atomizing performance is better.
In other embodiments, the shape of the air inlet of the atomizing chamber 101 may be set to other shapes, for example, the air inlet of the atomizing chamber 101 may be in any shape such as a circle, an ellipse, a square, a diamond, and the like, the air-equalizing sheet 40 may also be in any other shape such as a rectangular sheet, a diamond sheet, and an elliptical sheet, and the shape of the air inlet of the atomizing chamber 101, that is, the concentric ring, may be the same as or different from the shape of the air-equalizing sheet 40, for example, the shape of the concentric ring may be in a circle or in the same shape as the shape of the air-equalizing sheet 40, or may be set in two different shapes, and may be designed as required. When the air inlet of the atomizing cavity 101 is in a circular isocentric symmetry pattern, first through holes 401 are distributed at each position on the outermost ring in the concentric ring; when the air inlet of the atomizing chamber 101 is in a non-centrosymmetric pattern, the first through holes 401 on the outermost ring of the plurality of concentric rings are only distributed corresponding to the side far away from the air flow channel 304, and the first through holes 401 are not arranged on the side near the air flow channel 304, so as to ensure the uniformity of air flow distribution.
Referring to fig. 6, 9 and 16, a first limiting structure 404 is disposed at a peripheral position of the gas distribution sheet 40, and the first limiting structure 404 is formed by partially cutting the peripheral edge of the gas distribution sheet 40. The lateral wall of the second recess 105 of the atomizing body 10 is formed with the second limit structure 106 corresponding to the shape of the first limit structure 404 of the gas homogenizing sheet 40, the limit function to the gas homogenizing sheet 40 can be realized through the cooperation assembly between the first limit structure 404 of the gas homogenizing sheet 40 and the second limit structure 106 of the second recess 105, play the foolproof effect when assembling the operation, avoid assembling the gas homogenizing sheet 40 to the second recess 105 because of not having limit structure and assembling the dislocation, or the gas homogenizing sheet 40 takes place to rotate etc. in the second recess 105 and leads to the position of each pore pair corresponding to the air inlet of the atomizing chamber 101 on the gas homogenizing sheet 40 to change, influence the gas homogenizing effect of the gas homogenizing sheet 40.
Specifically, as shown in fig. 16, in the present embodiment, the gas equalizing sheet 40 is circular, a straight edge is cut on the circumference of the gas equalizing sheet 40, and the cut straight edge is the first limiting structure 404. The second groove 105 is cylindrical, the side wall of the second groove is an arc surface, a part of the side wall of the second groove 105 corresponds to the straight edge of the gas homogenizing plate 40 to form a plane (as shown in fig. 9), the plane of the side wall of the second groove 105 is a second limiting structure 106, the straight edge of the gas homogenizing plate 40 and the plane of the second groove 105 are matched and assembled to limit the gas homogenizing plate 40, and the gas homogenizing plate 40 is ensured to be correctly assembled in the second groove 105 and cannot rotate.

The heating element 30 adopts a parallel connection mode, so that the heat exchange area between the heating element 30 and the air can be effectively increased under the condition of the same resistance value, and the heat exchange effect is enhanced.
