Referring to fig. 1-6, the present invention provides a heating assembly for heating and atomizing low-temperature non-combustible herbs. Specifically, the heat generating component includes a first electrode 100, a conductive case 200, and a heat generating body 300. The conductive housing 200 has a first end portion 210 and a second end portion 220, and the first end portion 210 and the second end portion 220 are respectively located at both ends of the conductive housing 200 in a length direction thereof. The conductive case 200 has a receiving groove 230 therein, and the heating element 300 is disposed in the receiving groove 230. In this embodiment, the conductive housing 200 serves as a second electrode having a polarity opposite to that of the first electrode 100, such as: when the polarity of the first electrode 100 is positive, the polarity of the conductive housing 200 as a second electrode is negative; alternatively, when the polarity of the first electrode 100 is negative, the polarity of the conductive case 200 as a second electrode is positive.

In practical applications, the conductive housing 200 may have a sheet structure or a block structure (as shown in fig. 1), and the length direction of the conductive housing 200 refers to the L direction shown in fig. 1; alternatively, the conductive housing 200 may be provided in a cylindrical shape (as shown in fig. 3 and 4), and the length direction of the conductive housing 200 may also be the axial direction of the conductive housing 200. Of course, the shape of the conductive housing 200 may also be other shapes, such as: a rectangular parallelepiped, a prism, etc., and is not limited thereto.

The heating element 300 is insulated from the conductive case 200 to prevent a short circuit between the heating element 300 and the conductive case 200. The heating element 300 has a first electrode lead 310 extended from the first end 210 of the conductive case 200 and connected to the first electrode 100, and a second electrode connection end 320, the heating element 300 is extended from the first electrode lead 310 toward the second end 220 of the conductive case 200 to the second electrode connection end 320, and the second electrode connection end 320 is connected to the second end 220 in the receiving groove 230.

The low-temperature non-combustible herbaceous substance may be a tobacco product, or may be other types of aerosol-generating products, such as tobacco leaves, cut tobacco, etc., which may be determined according to actual use requirements of users, and this embodiment does not specifically limit the present invention.

The low-temperature non-combustible tobacco product is mainly an aerosol generating product made of tobacco shreds, tobacco particles, plant fragments, tobacco essence, propylene glycol and other materials, and is generally in a columnar shape (such as a cylindrical shape), so that the low-temperature non-combustible tobacco product is also called a low-temperature non-combustible cigarette. Under low temperature heating condition, volatile substances such as nicotine and other aromatic substances inside the container can volatilize without generating solid particles, and only atomized steam is generated. It will be understood that low temperatures herein refer to temperatures which enable herbs to produce aerosols without combustion, and are typically in the range of 200 ℃ to 400 ℃.

In the present embodiment, the overall resistance of the conductive case 200 is preferably 0.003 Ω to 0.025 Ω. In practice, the resistance of the first electrode 100 is equal or approximately equal to the resistance of the conductive shell 200, i.e. the conductive shell 200 may act as a second electrode of opposite polarity to the first electrode 100. By "approximately equal" it is understood that the difference between the resistance of the first electrode 100 and the resistance of the conductive housing 200 is negligible.

Since the first electrode 100 is disposed at the periphery of the conductive shell 200, the first electrode 100 is disposed near the first end 210 of the conductive shell 200, and the heating element 300 is disposed in the receiving groove 230 of the conductive shell 200, the first electrode lead 310 of the heating element 300 needs to extend from the first end 210 of the conductive shell 200 to the outside of the conductive shell 200 and be connected to the first electrode 100; the heating element 300 extends to a second electrode connection terminal 320 in a direction from the first end 210 of the conductive case 200 to the second end 220 of the conductive case 200 within the receiving groove 230, and the second electrode connection terminal 320 is directly connected to the second end 220.

The utility model provides a technical scheme, this heating element includes first electrode 100, electrically conductive shell 200 and heat-generating body 300, electrically conductive shell 200 is as the opposite second electrode with first electrode 100's polarity, heat-generating body 300 sets up with electrically conductive shell 200 is insulating mutually, the first electrode of heat-generating body 300 is drawn forth end 310 and is extended the first end 210 department of electrically conductive shell 200 and be connected the setting with first electrode 100, heat-generating body 300 draws forth end 310 from first electrode and extends to second electrode link 320 towards electrically conductive shell 200's second end 220, second electrode link 320 is connected the setting with second end 220 in holding tank 230. In this way, the conductive case 200 is used as a second electrode having a polarity opposite to that of the first electrode 100, and the second electrode connection terminal 320 of the heating element 300 is directly connected to the conductive case 200, so that a current path is formed between the first electrode 100, the heating element 300, and the conductive case 200. In this way, the second electrode connecting terminal 320 of the heating element 300 can be directly connected with the second end 220 of the conductive shell 200, so that the second electrode connecting terminal 320 of the heating element 300 does not need to be wound back to the first end 210 of the conductive shell 200 from the second end 220 of the conductive shell 200, thereby ensuring that the heating element 300 can reduce the length of the heating element 300 wound back to the first end 210 of the conductive shell 200 from the second end 220 of the conductive shell 200 under the condition that the heating element 300 covers the conductive shell 200 as much as possible, and further saving the material cost and the manufacturing cost of the heating element 300.

The heating assembly in the embodiment is suitable for heating and atomizing low-temperature non-combustible herbaceous substances. In practical application, the heating component is in direct contact with the herbaceous substance, so that the herbaceous substance can be directly heated and atomized after the heating component is electrified and heated. In the structural design of the present embodiment, the heat generating body 300 is disposed in the receiving groove 230 of the conductive housing 200, so that the conductive housing 200 is in contact with the herbal substances. Like this, when inserting the herbaceous class material and establishing at the heating element or withdrawing from the heating element with herbaceous class material, can produce the interact power between electrically conductive shell 200 and the herbaceous class material, and can not produce the interact power between heat-generating body 300 and the herbaceous class material to can protect heat-generating body 300 can not damaged, increase heat-generating body 300's life.

Further, in order to prevent a short circuit between the conductive case 200 and the heat-generating body 300, the conductive case 200 and the heat-generating body 300 are provided to be insulated from each other.

In some structural designs, the surface of the conductive case 200 facing the heat-generating body 300 is formed with an insulating layer (not shown) so that the conductive case 200 is insulated from the heat-generating body 300 by the insulating layer of the surface thereof. In this embodiment, the insulating layer may be formed in different manners based on the material of the conductive housing 200. For example, when the conductive shell 200 is made of titanium, the insulating layer may be formed on the surface of the conductive shell 200 facing the heating element 300 by using a micro-arc oxidation process; alternatively, the insulating layer may be formed by applying an insulating substance to the surface of the conductive case 200 facing the heat-generating body 300 using a coating process.

The micro-arc oxidation is a method for enhancing and activating a reaction generated on an anode by utilizing arc discharge on the basis of common anodic oxidation so as to form a high-quality reinforced ceramic membrane on the surface of a workpiece made of metals such as aluminum, titanium, magnesium and the like and alloys thereof.

The micro-arc oxidation process has the following advantages:

(1) The surface hardness of the material is greatly improved, the microhardness is 1000-2000 HV, and can reach 3000HV at most, and the microhardness can be comparable to that of hard alloy and greatly exceeds the hardness of high-carbon steel, high-alloy steel and high-speed tool steel after heat treatment;

(2) Good wear resistance;

(3) The alloy material has good heat resistance and corrosion resistance, and fundamentally overcomes the defects of aluminum, magnesium and titanium alloy materials in application, so that the technology has wide application prospect;

(4) The insulating property is good, and the insulating resistance can reach 100 MOmega;

(5) The solution is environment-friendly and meets the requirement of environment-friendly discharge;

(6) The process is stable and reliable, and the equipment is simple;

(7) The reaction is carried out at normal temperature, the operation is convenient, and the control is easy;

(8) The ceramic membrane grows in situ on the substrate, the combination is firm, and the ceramic membrane is compact and uniform.

As can be seen from the above, the insulation layer is preferably formed on the surface of the conductive shell 200 facing the heat-generating body 300 by using a micro-arc oxidation process.

In other structural designs, the surface of the heat-generating body 300 may also be formed with an insulating layer. The insulating layer may also be formed on the surface of the heating element 300 by using a micro-arc oxidation process or a coating process based on the material of the heating element 300, which is specifically described above and not described herein again.

In still other structures, the conductive case 200 and the heating element 300 are insulated from each other by an insulating filler, and at this time, a gap (not shown) is formed between the heating element 300 and the inner sidewall of the conductive case 200, in which the receiving groove 230 is formed, and the gap is filled with the insulating filler, so that the heating element 300 and the conductive case 200 are insulated from each other. The insulating filler in this embodiment may be a material such as a high temperature resistant silicone rubber or rubber, and is not limited herein.

It should be noted that the above two types of insulating layer and insulating filler can be used independently or in combination, so that the heating element 300 and the conductive case 200 are insulated from each other to prevent short circuit.

In some embodiments, the material of the heating element 300 is pure metal, alloy material, or conductive ceramic, etc., and the material of the conductive case 200 is pure metal, alloy material, stainless steel, or conductive ceramic, etc. In the present embodiment, the material of the heating element 300 is preferably an alloy material, and the material of the conductive case 200 is preferably a pure metal.

Specifically, the material of the heating element 300 is titanium, magnesium, aluminum, iron-chromium-aluminum alloy, titanium-nickel alloy, conductive ceramic, or the like, and the material of the conductive case 200 is aluminum, copper, titanium, aluminum alloy, copper alloy, stainless steel, conductive ceramic, or the like. More preferably, the heating element 300 is made of iron-chromium-aluminum alloy, which has high use temperature, long service life, high surface load, good oxidation resistance and low price. The conductive shell 200 is made of aluminum or titanium, has high thermal conductivity, and can conduct more heat generated after the heating element 300 is electrified to the herbaceous substance in direct contact with the heating element, so that the herbaceous substance is more sufficiently atomized.

When the conductive case 200 and the heating element 300 are both made of conductive ceramics, the conductive ceramics may be a mixture of conductive powder and at least one of silicon carbide, silicon oxide, aluminum oxide, and zirconium oxide, and the conductive powder may be at least one of titanium nitride, zirconium nitride, titanium carbonitride, titanium carbide, zirconium carbide, thallium carbide, hafnium carbide, titanium boride, zirconium boride, thallium boride, hafnium boride, molybdenum silicide, and tungsten carbide.

In other embodiments, the material of the heat-generating body 300 is a valve metal material; alternatively, the conductive shell 200 is made of a valve metal material; alternatively, the material of both the heat-generating body 300 and the conductive case 200 is a valve metal material.

In this embodiment, the metal titanium, the metal magnesium, the metal aluminum, and the alloy material thereof may be used as the valve metal material. In practical application, the material of the heating element 300 is preferably metallic titanium, which has the characteristics of no pollution, light weight, strong corrosion resistance and the like.

It should be noted that the materials of the conductive shell 200 and the heating element 300 can be the same valve metal, for example, the materials of the conductive shell 200 and the heating element 300 are both metal titanium; alternatively, the materials of the conductive case 200 and the heat generating body 300 may be different valve metals, and are not limited herein.

Based on the above description, the resistance of the heat-generating body 300 in the present embodiment is equal to or greater than fifty times the resistance of the conductive case 200. Preferably, the resistance of the heat-generating body 300 is at least two orders of magnitude higher than that of the conductive case 200, that is, the resistance of the heat-generating body 300 is one hundred times or more higher than that of the conductive case 200. For example, the resistance of the heat-generating body 300 may be one hundred times or one thousand times the resistance of the conductive case 200, or the like.

As is apparent from the above description of the embodiments, the overall resistance of the conductive case 200 is between 0.003 Ω to 0.025 Ω, that is, the resistance of the heating element 300 is preferably between 0.3 Ω to 2.5 Ω.

Note that, if the material of the heat-generating body 300 is the same as that of the conductive case 200, in order to set the resistance of the heat-generating body 300 to be one hundred times or more the resistance of the conductive case 200, the thickness of the heat-generating body 300 is set to be much smaller than that of the conductive case 200 in this embodiment, that is, the cross-sectional area of the heat-generating body 300 is reduced, and it is understood from the calculation formula of the resistance R = ρ (L/S) that the smaller the cross-sectional area of the heat-generating body 300 is, the larger the resistance is. In this manner, by reducing the cross-sectional area of the heat-generating body 300, the difference between the resistance of the heat-generating body 300 and the resistance of the conductive case 200 is increased, thereby satisfying that the resistance of the heat-generating body 300 is set to be one hundred times or more the resistance of the conductive case 200.

If the materials of the heating element 300 and the conductive shell 200 are different, the heating element 300 can increase the resistance of the heating element 300 by selecting a material with higher resistivity rho according to a calculation formula of the resistance; alternatively, the heat-generating body 300 may increase the resistance of the heat-generating body 300 itself by increasing the conductor length of the heat-generating body 300; alternatively, the heat-generating body 300 may be formed by reducing the cross-sectional area of the conductor of the heat-generating body 300 to increase the resistance of the heat-generating body 300 itself; alternatively, the heating element 300 may be formed by selecting a material having a high resistivity ρ, increasing the length of the conductor of the heating element 300, and decreasing the cross-sectional area of the conductor of the heating element 300 to increase the resistance of the heating element 300 itself, and the like, without being limited thereto.

Further, in the case where the material of the heat-generating body 300 is different from the material of the conductive case 200, the resistivity of the heat-generating body 300 is equal to or more than fifty times the resistivity of the conductive case 200. Preferably, the resistivity of the heat-generating body 300 is at least two orders of magnitude higher than that of the conductive case 200, that is, the resistivity of the heat-generating body 300 is one hundred times or more higher than that of the conductive case 200. For example, the resistivity of the heat generating body 300 may be one hundred times or one thousand times that of the conductive case 200.

In the case where the material of the heat-generating body 300 is the same as that of the conductive case 200, the heat-generating body 300 has the same resistivity as that of the conductive case 200. It should be noted that, the material of the heating element 300 and the material of the conductive shell 200 are both conductive ceramics, and the resistivity between the heating element 300 and the conductive shell 200 can be changed by changing the ratio of the conductive ceramic material in the heating element 300 to the conductive ceramic material in the conductive shell 200, so that the resistivity of the heating element 300 is greater than or equal to fifty times the resistivity of the conductive shell 200. For example, when zirconia and titanium nitride are used as the material of the heating element 300 and the conductive case 200, the specific resistance of the heating element 300 is made fifty times or more of the specific resistance of the conductive case 200 by adjusting the weight ratio between the zirconia and the titanium nitride. The material forming the heat-generating body 300 and the conductive case 200 in the present embodiment may include, but is not limited to, titanium powder, carbon black, or a solution such as a PVA (polyvinyl alcohol) solvent, etc., in addition to the above-described zirconia and titanium nitride, so that the heat-generating body 300 and the conductive case 200 are formed to have metallic electrical characteristics and ceramic structural characteristics.

Based on the above embodiment, the heat-generating body 300 is provided inside the conductive case 200 to protect the structure of the heat-generating body 300 by the conductive case 200. The present application provides some structural designs of the conductive housing 200 and the heat generating body 300.
