The two or more conductive regions are conductive region a, conductive region B, and conductive region … …, respectively, and conductive region a and conductive region B are adjacent conductive regions. The conductive areas can be designed as follows:
(1) two certain electronic components distribution of resistance is different, then electrically conductive regional A and electrically conductive regional B contain above-mentioned two electronic components respectively, and border resistance, sub-resistance and connecting resistance are electronic components, for example:

The "difference in the distribution of the resistance values of the electronic components" in the above case is reflected in the following aspects: (a) under the same shape structure density, different materials exist among the electronic components, and the different materials have different electric conductivities, so that the resistance values of the electronic components are different, such as an iron ring and a copper ring; (b) under the condition of the same structure, density and conductivity materials, electronic components form different shapes, so that the resistance distribution of the electronic components is different, such as an S shape and a straight shape; (c) under the condition of the same shape, density and conductivity materials, the electronic components have different structures, so that the resistance distribution of the electronic components is different, such as a hollow cylinder type and a solid cylinder type; (d) under the same shape, structure and conductive material, the density distribution of the electronic components is different, so that the resistance distribution of the electronic components is different.
(2) Under the condition that the resistance values of a plurality of electronic components are distributed in the same manner, and the connection modes of two or more electronic components are different, the conductive area a and the conductive area B respectively comprise circuit connection areas with different connection modes of the electronic components.
In the above case, "the connection modes between two or more electronic components are different", which is embodied in that: (a) the circuit connection modes are different, namely, the circuit connection modes of series connection and parallel connection are different, for example, the resistance value distribution of a conductive area A containing the '-sub-resistor- (sub-resistor parallel connection resistor) -sub-resistor-' is different from that of a conductive area B containing the '-sub-resistor-connection resistor-sub-resistor'; (b) the spatial connection positions are different, for example, if the connection resistor is connected with the upper end of the sub-resistor, the resistance distribution of the conductive region a of the 'half part of the sub-resistor + the connection resistor' and the conductive region B of the 'half part of the sub-resistor + the resistor of the corresponding region of the connection resistor' is different by taking the middle of the sub-resistor as a boundary.
(3) In different parts of the same electronic component, the resistance value distribution is different, and then the conductive area a and the conductive area B respectively contain two areas of the electronic component with different resistance value distributions, for example:
(3-1) in the edge resistor a, if the resistance distribution of the upper half part is different from that of the lower half part, the conductive area A comprises the upper half part of the edge resistor a, and the conductive area B comprises the lower half part of the edge resistor a;
(3-2) in the sub-resistor c, if the resistance distribution of the upper half part is different from that of the lower half part, the conductive area A contains the upper half part of the sub-resistor c, and the conductive area B contains the lower half part of the sub-resistor c;
and (3-2) in the connecting resistor e, if the resistance distribution of the upper half part is different from that of the lower half part, the conductive area A comprises the upper half part of the connecting resistor e, and the conductive area B comprises the lower half part of the connecting resistor e.
Therefore, the scheme aims to provide the non-uniform heating element, the non-uniform heating characteristic is caused by different resistance value distribution, and the resistance value distribution in two adjacent conductive areas is different, so that the heating power is different after the two adjacent conductive areas are electrified, and the non-uniform heating is realized. When the atomizer with non-uniform heating is used, the heating speed of the part with high resistance of the heating element is high, and the heating speed of the part with low resistance of the heating element is low. In the production process of the aerosol generating device, the structure of the atomizer in the aerosol generating device can be used for judging which part of the atomizer has more tobacco juice and which part has less tobacco juice after the tobacco juice is injected; select the piece that generates heat of suitable structure, and then when realizing the interior tobacco juice of make full use of atomizer, avoid the tobacco juice local dry combustion method, paste the core and distribute harmful gas's the condition.
To this end, the present solution provides several embodiments as follows:
the first embodiment is as follows:
as shown in fig. 1 and 2, a non-uniformly heated heat generating member 100 includes two edge resistors, six sub-resistors, and seven connecting resistors 2. The edge resistor and the sub-resistor are both circular, and for this reason, the edge resistor is referred to as resistor side ring 1, and the sub-resistor is referred to as resistor sub-ring 3. In some embodiments, the edge resistance and/or the sub-resistance are non-annular. In this embodiment, the resistance side ring 1 includes a circular ring part 11 and a straight rod part 12, the straight rod part 12 is used as an electrical connection part, and the lower end of the straight rod part 12 is used for electrically connecting with a positive electrode or a negative electrode of a battery; a resistor 2 is connected in series between the resistor side ring 1 and the resistor sub-ring 3, and a resistor 2 is also connected in series between every two resistor sub-rings 1; the entire heat generating member 100 is integrally formed. The planes of the two resistance side rings 1 and the six resistance sub-rings 3 are parallel to each other, so that the gravity center of the resistance side ring 1 is located on the straight line of the straight rod part 12 of the resistance side ring, and the connecting resistor 2 is perpendicular to the resistance side ring 1 and the resistance sub-rings 3. Because the six resistor sub-rings 3 are the same in shape, structure, density and resistivity of the adopted materials, the resistor distribution of the six resistor sub-rings 3 is the same; since the shape, structure, density, and resistivity of the material used are also the same between the two resistive edge rings 1, the resistance distributions of the two resistive edge rings 1 are also the same.
The specific analysis is as follows:
(1) all parts of the resistance side ring 1 are paved by using materials with the same density and the same resistivity, and the shape of the circular ring part 11 of the resistance side ring 1 is different from that of the straight rod part 12, so that the resistance distribution of the circular ring part 11 is different from that of the straight rod part 12, as shown in fig. 2, two adjacent conductive areas a and conductive areas B are divided, wherein the conductive area a comprises the circular ring part 11 of the resistance side ring, and the conductive area B comprises the straight rod part 12 of the resistance side ring; if the resistance value of the circular ring part 11 is greater than that of the straight rod part 12, the resistance value of the conductive area a is greater than that of the conductive area B, that is, the heating power of the conductive area a is greater than that of the conductive area B after the circular ring part is energized, and therefore, the upper heating power is greater than the lower heating power after the circular ring part 1 is energized.
(2) The distance between the resistor sub-rings 3 is gradually increased from the two ends to the middle, that is, the resistance of the connecting resistor is gradually increased from the two ends to the middle, as shown in fig. 2, the whole heating element is divided into three conductive areas at equal distance horizontally, namely, the left conductive area D, the middle conductive area E and the right conductive area F, it can be known that the resistance value in the left conductive area D is greater than that in the middle conductive area E, and the resistance value in the right conductive area F is greater than that in the middle conductive area E, that is, the resistance distribution of the whole heating member 100 is "large resistance values at both ends and small resistance value in the middle", the corresponding result is that the heating power of the heating member 100 is "large heating power at both ends and small heating power in the middle", the device is suitable for the situation that the tobacco juice injection speed is high at two ends and low in the middle, and is suitable for aerosol generating devices with liquid inlets of the tobacco juice in the atomizing cavity at two ends.
Example two:
the difference between the scheme and the first embodiment is as follows: as shown in fig. 3, a non-uniform heating element 100 includes two resistance side rings 1, four resistance sub-rings 3 and three connecting resistors 2, the resistance side rings 1 include circular ring portions 11 and straight rod portions 12, the vertical portions 12 of the resistance side rings 1 are perpendicular to the circular ring portions, and the resistance sub-rings 3, the connecting resistors 2 and the circular ring portions 11 of the resistance side rings 1 are all located on the same plane.
The specific analysis is as follows:
(2) all parts of the resistance side ring 1 are paved by using materials with the same density and the same resistivity, and the shape of the circular ring part 11 of the resistance side ring 1 is different from that of the straight rod part 12, so that the resistance distribution of the circular ring part 11 is different from that of the straight rod part 12, as shown in fig. 2, two adjacent conductive areas a and conductive areas B are divided, wherein the conductive area a comprises the circular ring part 11 of the resistance side ring, and the conductive area B comprises the straight rod part 12 of the resistance side ring; if the resistance value of the circular ring part 11 is greater than that of the straight rod part 12, the resistance value of the conductive area a is greater than that of the conductive area B, that is, the heating power of the conductive area a is greater than that of the conductive area B after the circular ring part is electrified, so that the upper heating power is greater than the lower heating power after the circular ring part 1 is electrified;
(2) the distance between the resistor sub-rings 3 is gradually increased from the two ends to the middle, that is, the resistance of the connecting resistor is gradually increased from the two ends to the middle, as shown in fig. 2, the whole heating element is divided into three conductive areas at equal distance horizontally, namely, the left conductive area D, the middle conductive area E and the right conductive area F, it can be known that the resistance value in the left conductive area D is greater than that in the middle conductive area E, and the resistance value in the right conductive area F is greater than that in the middle conductive area E, that is, the resistance distribution of the whole heating member 100 is "large resistance values at both ends and small resistance value in the middle", the corresponding result is that the heating power of the heating member 100 is "large heating power at both ends and small heating power in the middle", the device is suitable for the situation that the tobacco juice injection speed is high at two ends and low in the middle, and is suitable for aerosol generating devices with liquid inlets of the tobacco juice in the atomizing cavity at two ends.
Example three:
the difference between the scheme and the first embodiment is as follows: as shown in fig. 4, 5 and 6, a non-uniform heating element 100 includes two resistor side rings 1, eight resistor sub-rings 3 and nine connecting resistors 2. The distance from each resistor sub-ring 3 to the adjacent resistor sub-ring 3/resistor side ring 1 is the same, and the shape, structure, density and material resistivity of all the connecting resistors 2 are the same, so that the resistance values of all the connecting resistors 2 are the same, and the resistance distribution is also the same. As can be seen from fig. 4 and 5, the resistor sub-rings 3 are different in shape and structure, and are divided into four rows: the first pair is a first left resistor sub-ring 3 and a first right resistor sub-ring 3; the second group is a left second resistor sub-ring 3 and a right second resistor sub-ring 3; the third pair is a left third resistor sub-ring 3 and a right third resistor sub-ring 3, the fourth pair is a left fourth resistor sub-ring 3 and a right fourth resistor sub-ring 3, wherein the shape, structure, density and material resistivity of the two resistor sub-rings 3 in each pair are the same, the resistance distribution of the two resistor sub-rings 3 in each pair is also the same, and the shape and structure of the resistor sub-rings 3 in two different pairs are different, that is, the resistance distribution of the resistor sub-rings 3 in different pairs is different.
At this time, conducting area division is performed, the conducting area M is the first left resistor sub-ring 3, the conducting area N is the second left resistor sub-ring 3, and since "resistance value is resistivity ═ conductor length/conductor cross-sectional area", under the condition that the material is the same and the length is the same, the resistance value of the thicker conductor is smaller; that is, the resistance value of the conductive region M is greater than that of the conductive region N.
The whole heating element is horizontally and equidistantly divided into three conductive areas, namely a left conductive area D, a middle conductive area E and a right conductive area F, so that the resistance value in the left conductive area D is greater than that of the middle conductive area E, the resistance value in the right conductive area F is greater than that of the middle conductive area E, the thickened part is gradually increased and then decreased from left to right in combination with the resistor sub-ring, and the resistance value of the resistor sub-ring 3 is gradually decreased and then increased. That is, the resistance of the resistor sub-ring 3 in this scheme is "big at both ends, small in the middle", and the condition that generates heat of the piece 100 that generates heat after circular telegram is "middle atomizing is slow, both ends atomizing is fast". The heating element of the scheme is more suitable for a mode of simultaneously feeding liquid from two ends when in use.
As shown in fig. 6, the resistances of the parts in the same resistor sub-ring 3 are not uniformly distributed, and a part of the resistor sub-ring 3 is thick and a part of the resistor sub-ring 3 is thin, and a connection line of centers of the resistor sub-ring is used as a central axis, a part above the central axis is used as an upper resistor area 31 of the resistor sub-ring 3, and a part below the central axis is used as a lower resistor area 32 of the resistor sub-ring. The resistance of the upper resistance region is thicker than that of the lower resistance region, and since the resistance value is resistivity, the length of the conductor and the cross-sectional area of the conductor, the resistance value of the thicker conductor is smaller and the resistance value of the upper resistance region is smaller than that of the lower resistance region under the condition of the same material and the same length. Taking the upper resistance area 31 of the same resistor sub-ring 3 as a conductive area A and the lower resistance area 32 of the same resistor sub-ring 3 as a conductive area B, the resistance value of the conductive area A is smaller than that of the conductive area B; when the conductive region A is electrified for use, the heating power of the conductive region A is lower than that of the conductive region B. In the present scheme, each resistor sub-ring 3 has a resistance value of the upper resistor area 31 smaller than that of the lower resistor area 32, and in summary, the heating condition of the whole heating element 100 is "slow upper atomization and fast lower atomization", which is suitable for a liquid inlet mode injected from the lower end.
Therefore, the heating element 100 of the present scheme is more suitable for the aerosol generating device in which two liquid inlets for the smoke liquid in the atomizing chamber are respectively located at two ends below the heating element 100.
Example four:
the difference between the scheme and the third embodiment is that: as shown in fig. 7 and 8, a non-uniform heating element 100 comprises two resistor side rings 1, six resistor sub-rings 3 and seven connecting resistors 2, wherein each resistor sub-ring 3 has a shape, a structure, a density and a conductivity. As shown in fig. 6, the resistances of the parts in the same resistor sub-ring 3 are not uniformly distributed, and a part of the resistor sub-ring 3 is thick and a part of the resistor sub-ring 3 is thin, and a connection line of centers of the resistor sub-ring 3 is used as a central axis, a part above the central axis is used as an upper resistor area 31 of the resistor sub-ring 3, and a part below the central axis is used as a lower resistor area 32 of the resistor sub-ring 3.
The upper resistance area 31 and the lower resistance area 32 of the resistance sub-ring 3 are both provided with a plurality of grooves, the groove of the upper resistance area 31 is an upper groove 311, and the groove of the lower resistance area 32 is a lower groove 321. The distance between the upper grooves 311 is greater than the distance between the lower grooves 321, and is characterized in that the lower grooves 321 of the resistor sub-ring 3 are dense, the upper grooves 311 of the resistor sub-ring 3 are sparse, and the number of the upper grooves 311 is less than that of the lower grooves 321. Moreover, the upper grooves 311 are arranged on two sides of the upper resistance region 31, and the lower grooves 321 are arranged on two sides of the lower resistance region 32, so that the left grooves and the right grooves of the resistor sub-ring 3 are symmetrical, and the resistor sub-ring 3 is prevented from bending and deforming after long-term heating.
Since "resistance value" is resistivity ═ conductor length/conductor cross-sectional area ", the thinner conductor has a larger resistance value when the material is the same and the length is the same. That is to say, the resistance value of the groove on the resistor sub-ring 3 is greater than the resistance value of the groove, so that the resistance value of the upper resistor area 31 in the same resistor sub-ring 3 is smaller than the resistance value of the lower resistor area 32 in the present scheme. Therefore, after the heating element 100 of the present embodiment is powered on, the heating power of the upper resistance region 31 is smaller than the heating power of the lower resistance region 32, and the lower end of the heating element 100 is atomized faster than the lower end of the heating element 100. Moreover, the contact area between the resistor sub-ring and the tobacco juice is increased due to the arrangement of the grooves, the tobacco juice atomizing speed of the resistor sub-ring is increased, the number of the lower grooves 321 in the lower resistor area 32 is more than that of the upper grooves 311 in the upper resistor area 31, and the tobacco juice heating atomizing speed of the lower resistor area 32 is higher than that of the upper resistor area 31.
When the resistor is used, two conductive areas are set to be a conductive area A and a conductive area B respectively, wherein the conductive area A is a set of upper resistance areas 31 of all the resistor sub-rings 3, namely an area above a central axis, and the conductive area B is a set of lower resistance areas 32 of all the resistor sub-rings 3, namely an area below the central axis; since the distribution of the resistance values of each resistor sub-ring 3 is identical, the resistance value of the conductive area a is larger than that of the conductive area B. Put together and say, the atomizing speed of the lower extreme of the piece 100 that generates heat of this scheme to the tobacco juice is greater than the atomizing speed of upper end to the tobacco juice, and this scheme is applicable to the aerosol generation device of the inlet of atomizing intracavity tobacco juice at piece 100 below both ends that generate heat. It should be noted that the numbers of the edge resistors, the connection resistors, and the sub-resistors in the above embodiments are only examples and are not limited, and the connection relationship may be adjusted according to the need and is also not limited.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
