Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 3, the atomizer with multiple heating passages of the present invention comprises: a circuit carrier 1, a positive electrode 2, a negative electrode 3 and a heating circuit 4. The positive electrode 2, the negative electrode 3 and the heating circuit 4 are disposed on the circuit carrier 1, and the heating circuit 4 is electrically connected between the positive electrode 2 and the negative electrode 3.
In an exemplary embodiment, the circuit carrier 1 is a main structure of a multiple heating path atomizer, and has a shape of a rectangular parallelepiped or a shape similar to a rectangular parallelepiped or a cylinder, and may also have other polyhedral shapes.
In an exemplary embodiment, the material of the circuit carrier 1 may be an insulator, and the insulator is formed with densely distributed oil holes and/or liquid storage channels, so that smoke can be stored by the oil holes and/or liquid storage channels, thereby avoiding the need to provide smoke cartridges. In this embodiment, the material of the circuit carrier 1 is selected from ceramic, crystal, glass, or a mixture thereof.
When the circuit carrier 1 is made of porous ceramic, the circuit carrier 1 is selected from one of oxide, nitride and carbide. Wherein, the oxide is selected from one of alumina, silica, zirconia, calcium oxide, titanium oxide, magnesium oxide and the like; the nitride is selected from one of silicon nitride, aluminum nitride and titanium nitride; the carbide is silicon carbide and the like.
In order to facilitate the conduction of the smoke, at least one channel region 11 with low liquid flow resistance is arranged on the circuit carrier body 1. The low liquid flow resistance channel zone 11 corresponds to the heating zone formed by the heating circuit 4, so that the resistance of the tobacco tar to enter the corresponding heating zone is smaller than the resistance to enter other zones. The shape of the low liquid flow resistance channel region 11 can be set according to actual requirements.
Since the oil guiding rate is proportional to the temperature difference, i.e. the temperature difference between the heating area and the circuit carrier 1, and inversely proportional to the transport distance of the liquid from the circuit carrier 1 to the heating area. Thus, the slots facilitate oil conduction. 0% grooving depth, equal to one time increased oil guiding speed. In particular, when the atomization rate is relatively high, the oil-carrying rate must be adapted to this, which would lead to dry-burning problems.
In an exemplary embodiment, the low liquid flow resistance channel region 11 is an oil guiding groove and/or an oil guiding hole opened on the circuit carrier 1. The oil guide groove is structurally characterized in that the radial shape of the oil guide groove is a strip-shaped or strip-like structure, and the oil guide hole is structurally characterized in that the radial shape of the oil guide groove is a circular or oval-shaped or strip-like structure.
The oil guide grooves and/or oil guide holes should be arranged at regions where no interference with the heating line 4 occurs. So, when atomizing heating, the tobacco tar of storage in the circuit supporting body 1 assembles gradually through the oil storage hole and flows into and lead the oil groove and/or lead in the oilhole to realize the concentrated heating of tobacco tar, overcome the insufficient problem of tobacco tar heating.
Preferably, the depth of the oil guide groove and/or the oil guide hole is 10% -90% of the thickness of the circuit carrier 1. Alternatively, the depth of the oil guide groove and/or the oil guide hole is 30-60% of the depth of the circuit carrier 1. For example, when the thickness of the circuit carrier 1 is 2mm, the depth of the oil guide groove and/or the oil guide hole is 0.6-1.2 mm.
In order to further improve the oil guiding effect of the low liquid flow resistance channel region 11, the oil guiding groove and/or the oil guiding hole may be filled with a material 12 having a higher porosity. Meanwhile, the extending direction of the oil guide groove and/or the oil guide hole is vertical to the surface of the heating circuit 4, so that the shortest stroke of an oil guide path is ensured.
Since the heating wire 4 is disposed on the circuit carrier 1, and the heating wire 4 is electrically connected between the positive electrode 2 and the negative electrode 3. During operation of the heating line 4, a heating area is formed on the circuit carrier 1. The oil guide groove and/or the oil guide hole are/is arranged at the position of the heating area. So, can furthest lead oil to the region that actually has atomizing ability, do not harm porous ceramic mechanical structure and bear the function of heating resistor simultaneously, promote atomization effect and atomizing volume. The specific shape and combination mode of the oil guide groove and/or the oil guide hole can be flexibly arranged according to the position of the heating area.
In an exemplary embodiment, the oil guide groove and/or the oil guide hole are integrally formed with the circuit carrier 1 by sintering using a mold, or the oil guide groove and/or the oil guide hole are formed by molding after the circuit carrier 1 is formed by sintering. Wherein the forming process comprises: mechanical machining, laser machining, plasma machining, and the like. The present embodiment may be combined with the above embodiments, that is, the oil guide groove and/or the oil guide hole in the above embodiments are formed by integrally sintering and molding the oil guide groove and/or the oil guide hole with the circuit carrier 1, or by forming the oil guide groove and/or the oil guide hole by molding after sintering and molding the circuit carrier 1.
The relationship between the depth of the slots/holes and the amount of atomization is demonstrated below.
A circuit carrier 1 with the length, width and thickness of 9x3x2mm and the groove/hole radius of 1mm is selected. The heating power is 6 watts. The data relationship between the average atomized amount and the depth of the grooves for the same liquid is shown in the following table:
| depth of slot/hole (mm) | Amount of atomization (μ l/s) |
| 0 | 0.9 |
| 0.3 | 1.1 |
| 0.5 | 1.3 |
| 0.8 | 1.6 |
| 1.0 | 2.0 |
| 1.3 | 2.5 |
| 1.5 | 3.2 |
It can be seen that through the slots/holes, and as the number of slots/holes increases, the atomization effect is improved.

In this way, the plurality of heating lines 4 are connected between the two electrodes in an intersecting or non-intersecting manner to form closed communication regions, and each closed communication region forms a heating region for atomizing and heating.
Meanwhile, the connection mode of intersection or non-intersection among the plurality of heating lines 4 also increases the line reliability. That is, when one or more lines are damaged, the lines are still communicated and still have the function of heating and atomizing. And because of the competition of electric power among the heating lines 4, the heating is more uniform and symmetrical, and further more uniform temperature distribution is obtained. In particular, the temperature uniformity of the heating zone can reach < 20 ℃. Preferably, < 5 ℃ can be achieved.
In an exemplary embodiment, the material of the heating line 4 is selected from one of silver, nickel, chromium, platinum, palladium, ruthenium, iron, gold, or an alloy thereof.

The positive temperature coefficient of resistance of the positive temperature coefficient of resistance material is preferably 100-3000 ppm/DEG C. So, through adopting positive resistance temperature coefficient material for the temperature of heating circuit is a little higher when all the way, through increasing resistance, reduces the branch road electric current, and then the automatic heating that reduces, finally realizes the even heating.
In the exemplary embodiment, any one of the heating lines 4 is a straight line, an arc, or a combination of a straight line and an arc, and the specific shape can be set according to the actual arrangement requirement.
In the exemplary embodiment, the width of any one heating line 4 is constant along its extension, or gradually decreases, the latter gradually increases, or decreases first and then increases, or increases first and then decreases, or decreases and increases periodically. That is, the width of the heating line 4 is not particularly limited.
In the exemplary embodiment, the resistance values of any two heating lines 4 are the same or different. The difference in resistance value can be realized by the difference in shape or the difference in material of the heating wire 4. The sheet resistance of any one of the heating lines 4 is 50-500 Ω/sq.
In an exemplary embodiment, any one of the heating traces 4 is disposed on the circuit carrier 1 by means of printing, sintering, vacuum coating or mechanical bonding.

In this embodiment, the heating lines 4 are substantially M-shaped, and the two heating lines 4 are symmetrically disposed. The heating zone is a closed communication zone enclosed by two heating lines 4 and electrodes 2, 3. The low liquid flow resistance channel zone 11 is one or more sub-zones within the heating zone.

At this time, when a short circuit occurs in the heating line 4, the current can be conducted as it is. And when there is a short circuit, the total resistance is reduced by a quarter. Meanwhile, the 8-shaped heating circuit 4 has a relatively simple structure, so that the shielding area of the circuit carrier 1 is relatively small, and the smoke oil can escape after being atomized.
As shown in fig. 7 and 8, in one embodiment, when the number of the heating lines 4 is three or more, each heating line 4 forms a network structure. Therefore, the current has a plurality of channels to connect the anode and the cathode. Therefore, when a resistance at a certain point in the circuit is changed greatly and even short-circuited, the heating line 4 can be conducted by other lines, and the reliability of the heating line 4 is improved. In the present embodiment, in order to form a network structure, the heating line 4 includes: first heating lines 41 electrically connected between the positive electrodes 2 and the negative electrodes 3, and at least one second heating line 42 connecting the respective first heating lines 41.
