To facilitate an understanding of the utility model, the utility model will now be described more fully hereinafter with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
Referring to fig. 1, 2 and 3, an atomizer 10 according to an embodiment of the present invention is provided for atomizing an atomizing medium in a liquid state to form an aerosol for inhalation by a user. The atomizer 10 includes a base 100, a heating assembly 200 and an electrode 300, the heating assembly 200 includes a heat insulator 210 and an infrared heating body 220, the electrode 300 is electrically connected to the infrared heating body 220, and when the electrode 300 energizes the infrared heating body 220, the infrared heating body 220 generates heat and radiates outwardly by infrared rays.
Referring to fig. 1, fig. 2 and fig. 3, in some embodiments, the substrate 100 is made of a porous ceramic material, so that a large number of micropores exist inside the substrate 100 and have a certain porosity, and due to the existence of the micropores, on one hand, the liquid atomizing medium can be transported in the micropores, so that the substrate 100 has a transport effect on the atomizing medium; on the other hand, the micropores have a certain storage function for the atomized medium, so that the substrate 100 has a buffer function for the atomized medium. The base body 100 may have a substantially cylindrical structure, for example, a cylindrical structure, and a receiving cavity 110 is formed in the base body 100, and the receiving cavity 110 may be a cylindrical cavity, that is, the cross section of the receiving cavity 110 is circular. The substrate 100 has a fogging surface 120, and the fogging surface 120 defines the boundary of the receiving cavity 110, and in this case, the fogging surface 120 has a ring shape. In a colloquial way, the atomizing surface 120 can be understood as an inner wall surface of the receiving chamber 110. The natural frequency of the base body 100 is approximately the same as the frequency of the infrared ray generated by the infrared heating body 220, and when the heat generated by the infrared heating body 220 is radiated on the atomization surface 120 through the infrared ray, the atomization surface 120 absorbs a large amount of infrared ray, so that the atomization surface 120 absorbs a large amount of heat generated by the infrared heating body 220 and heats up, and then the atomization medium on the atomization surface 120 is atomized to form aerosol.
Referring to fig. 1, 2 and 3, in some embodiments, the thermal insulator 210 may also be substantially cylindrical, and the thermal insulator 210 is at least partially received in the receiving cavity 110 of the substrate 100. The heat insulator 210 is provided with an accommodating cavity 211, the accommodating cavity 211 is isolated from the accommodating cavity 110 without communicating with each other, the part of the heat insulator 210 surrounding the accommodating cavity 211 can be entirely located in the accommodating cavity 110, and in popular terms, the accommodating cavity 211 is entirely located within the range of the accommodating cavity 110. The infrared heater 220 is accommodated in the accommodating cavity 211, that is, the infrared heater 220 is hidden in the heat insulator 210, so that the atomizing surface 120 surrounds the infrared heater 220. Since the thermal insulator 210 is spaced apart from the atomization surface 120, a gap 130 exists between the thermal insulator 210 and the atomization surface 120, so that the thermal insulator 210 and the entire heating assembly 200 are in non-contact relation with the atomization surface 120; in fact, the spacing gap 130 is a part of the receiving cavity 110. The width of the spacing gap 130 is uniformly set, that is, the width of the spacing gap 130 is equal everywhere, the width a of the spacing gap 130 may range from 0.3mm to 1.5mm, and the specific value of the width a may be 0.3mm, 1.0mm, or 1.5 mm. The insulator 210 has an inner surface 212 and an outer surface 213, the inner surface 212 delimits the receiving chamber 211, the outer surface 213 is disposed adjacent to the atomizing surface 120, the clearance gap 130 is located between the outer surface 213 and the atomizing surface 120, it is understood that the atomizing surface 120 and the outer surface 213 together delimit the clearance gap 130, and the aerosol generated by atomization on the atomizing surface 120 is discharged into the clearance gap 130 first.
The insulator 210 has two important characteristics, the first being that the insulator 210 has a low thermal conductivity. When the infrared heating body 220 generates heat in the accommodating cavity 211, the heat is difficult to be conducted in the heat insulator 210, that is, the heat is difficult to be transferred from the inner surface 212 to the outer surface 213, so that the heat generated by the infrared heating body 220 is difficult to be transferred to the outer surface 213 of the heat insulator 210 in a solid medium by means of heat conduction, and the temperature of the outer surface 213 of the heat insulator 210 is far lower than the temperature of the infrared heating body 220, thereby ensuring the heat insulation effect of the heat insulator 210. The second is that the natural frequency of the heat insulator 210 is greatly different from the frequency of the infrared ray generated from the infrared heating body 220, and has a penetrating function to the infrared ray. Therefore, in the process that the infrared ray generated by the infrared heating body 220 penetrates through the heat insulator 210, the heat insulator 210 is difficult to absorb the infrared ray, so that the heat insulator 210 is difficult to absorb the heat in the infrared ray, the heat generated by the infrared heating body 220 is difficult to transmit to the outer surface 213 of the heat insulator 210 in a heat radiation manner, the temperature of the outer surface 213 of the heat insulator 210 is far lower than the temperature of the infrared heating body 220, and the heat insulation effect of the heat insulator 210 can be ensured.
In some embodiments, the infrared heating body 220 and the inner surface 212 of the heat insulator 210 are disposed at an interval, that is, the infrared heating body 220 and the inner surface 212 form a non-contact relationship, so as to prevent heat generated by the infrared heating body 220 from being directly transferred to the heat insulator 210, and the receiving cavity 211 can be vacuumized to form a vacuum state, thereby eliminating a fluid medium in the receiving cavity 211, preventing heat generated by the infrared heating body 220 from being transferred to the inner surface 212 and further transferred to the outer surface 213 in the fluid medium by a heat conduction manner, and further improving the heat insulation effect of the heat insulator 210. The receiving cavity 211 can be filled with halogen gas, on one hand, the halogen gas has a low thermal conductivity, and the heat generated by the infrared heating body 220 is difficult to be conducted to the inner surface 212 and further to the outer surface 213 through the halogen gas, so as to improve the heat insulation effect of the heat insulator 210. On the other hand, the infrared heating body 220 can be protected, and the infrared heating body 220 is prevented from generating oxidation reaction in the heating process to influence the service life of the infrared heating body.
Referring to fig. 1, 2 and 3, in some embodiments, the thermal insulator 210 includes a quartz tube 214 and two thermal insulation plugs 215, the quartz tube 214 may be a hollow transparent tubular structure, the number of the thermal insulation plugs 215 may be two, and the two thermal insulation plugs 215 respectively plug the upper end and the lower end of a tube cavity of the quartz tube 214, so that a portion of the tube cavity forms the accommodating cavity 211. The insulating plug 215 may be made of a ceramic material and the quartz tube 214 may be made of a quartz material, such that the insulating plug 215 and the quartz tube 214 are detachably connected. The electrode 300 is inserted into the thermal insulation plug 215 at the lower end of the quartz tube 214 and extends into the accommodating cavity 211, so that the electrode 300 and the infrared heater 220 form an electrical connection relationship. The wall thickness of the quartz tube 214 may be 0.4mm to 1.0mm, and the cross-sectional size of the quartz tube 214 may be 1.5mm to 3.0mm, for example, when the quartz tube 214 is cylindrical, the cross-sectional dimension of the quartz tube 214 is the outer diameter of the quartz tube 214, and the wall thickness of the quartz tube 214 is half of the difference between the outer diameter and the inner diameter of the quartz tube 214. The thickness of the quartz tube 214 is small, and the intrinsic properties of the material of the quartz tube 214 itself are added, so that the infrared rays generated by the infrared heater 220 can effectively penetrate through the quartz tube 214 and be absorbed by the atomization surface 120. Certainly, the thickness of the thermal insulation plug 215 may be relatively larger, so as to effectively prevent infrared rays from penetrating through the thermal insulation plug 215, prevent heat generated by the infrared heating body 220 from radiating to an area outside the atomization surface 120 through the thermal insulation plug 215, ensure that all heat is radiated to the atomization surface 120, and improve the energy utilization rate of the infrared heating body 220.
The insulating plug 215 has an insulating surface 215a, which insulating surface 215a delimits part of the receiving chamber 211, i.e. the insulating surface 215a forms part of the inner surface 212, i.e. the inner surface 212 comprises the insulating surface 215 a. The insulator 210 also includes a reflective layer attached to the insulating surface 215 a. The reflective layer has a reflective effect on infrared rays, and when a part of infrared rays generated by the infrared heating body 220 are radiated towards the heat insulation plug 215, the reflective layer totally reflects the part of infrared rays, so that the infrared rays are further prevented from penetrating through the heat insulation plug 215, and the energy utilization rate of the infrared heating body 220 is further improved. In other embodiments, the entire insulator 210 is made of quartz material and is integrally formed to form the receiving cavity 211.
Referring to fig. 3, 4 and 5, in some embodiments, infrared heater 220 is made of high temperature resistant material such as nichrome, ferrochrome or tungsten alloy, and infrared heater 220 includes an infrared material film layer at the outermost layer. Of course, the infrared heating body 220 may also be made of conductive infrared high-radiation material such as carbon fiber. The infrared heating body 220 has a spiral shape, for example, the infrared heating body 220 includes a sheet-shaped spiral sheet 221; for another example, the infrared heating body 220 includes a plurality of strip-shaped spiral strips 222, the plurality of spiral strips 222 are arranged side by side, the cross-sectional dimension of each spiral strip 222 may be equal, and the value range thereof is 0.1mm to 0.15 mm. By arranging the spiral sheet 221 or the plurality of spiral strips 222 arranged side by side, the surface area of the infrared heating body 220 can be increased reasonably, thereby increasing the radiation area of the infrared heating body 220 to infrared rays. The spiral diameter of the infrared heating body 220 may be 1.2mm to 2.5mm, the pitch of the infrared heating body 220 may be 1.0mm to 1.5mm, the height of the infrared heating body 220 may be 3mm to 6mm, and the height of the infrared heating body 220 may be understood as the axial length of the infrared heating body 220. When the infrared heating body 220 generates heat, the heating temperature of the infrared heating body 220 may be 800 to 1200 ℃.
When the atomizer 10 is operated, the external air enters the gap 130 from the lower end of the housing 110 to carry the aerosol, and leaves the entire housing 110 from the upper end of the housing 110 to be absorbed by the user, and the flow path of the air is indicated by the dotted arrows in fig. 3.
If the atomizer 10 adopts the design mode with the direct attached to the atomising surface 120 of heating resistor silk, to this design mode, heating resistor silk circular telegram produces the heat, and this heat wears to establish to atomising surface 120 through heat-conducting mode, and the heat of heating resistor silk is absorbed to the atomizing medium on the atomising surface 120 and is atomized and form aerosol, but this design mode has several following defects at least:
firstly, the heat is transmitted through a heat conduction mode, so that the chances of heat absorption in each region on the atomization surface 120 are not uniform, and therefore the heat is unevenly distributed on the atomization surface 120, for example, the region on the atomization surface 120 close to the heating resistance wire absorbs more heat to form a high-temperature region with higher temperature, and the atomization medium in the high-temperature region is burnt due to overhigh temperature, so that the aerosol has scorched flavor to influence the mouth feel of the user. The region of keeping away from the heating resistor silk simultaneously absorbs the heat less and forms the lower low temperature region of temperature, and the atomizing medium that is located this low temperature region will be because of the temperature crosses lowly and can't fully atomize for the atomizing granule in the aerosol is great and influences the suction taste. Of course, the temperature in the low-temperature region cannot even reach the atomization temperature and cannot atomize the atomization medium, so that the atomization amount of the atomization medium in unit time is reduced, and the concentration of the aerosol is low.
Secondly, the heating resistance wire is usually made of heavy metal materials, and in the working process of the heating resistance wire, the heating resistance wire and the atomizing medium attached to the heating resistance wire generate a series of physical and chemical reactions at high temperature, so that heavy metal elements enter aerosol and are absorbed by a user, and thus the damage to the health of the user can be caused, and the whole atomizer 10 has safety risks. Meanwhile, the atomizing medium attached to the heating resistance wire can absorb heat in the atomizing process, so that the temperature of the heating resistance wire is reduced, temperature fluctuation exists in the heating resistance wire during working, and the smoking taste of aerosol can be influenced.
Thirdly, because there are two sources in the production of aerosol, one is the region that does not set up the resistance heating wire on the atomizing surface 120, and this region marks as the atomizing region of atomizing surface 120, and the atomizing medium supply in this atomizing region is more and forms more aerosol. The other is the surface area of the heating resistance wire, because the heating resistance wire is usually made of compact metal or alloy material, the penetration and transmission capability of the heating resistance wire to the atomizing medium are lower than that of the atomizing core, so the supply amount of the atomizing medium in the surface area is less and less aerosol is formed, and in fact, the aerosol generated by the atomizing medium on the surface area of the heating resistance wire can be ignored relative to the aerosol generated by the atomizing medium on the atomizing area of the atomizing surface 120. Therefore, the heating resistance wire occupies a part of the area of the atomizing surface 120, so that the effective area of the atomizing area is smaller than the total area of the atomizing surface 120, and finally the atomizing amount of the atomizing medium in unit time is difficult to increase to influence the concentration of the aerosol.
Fourthly, a part of heat of the heating resistance wire is transferred to the area outside the atomizing surface 120, so that the utilization rate of the heat of the heating resistance wire is reduced, and the atomizing amount and the aerosol concentration of the atomizing medium in unit time are influenced.
Fifthly, the airflow directly contacts with the heating resistance wire to absorb the heat of the heating resistance wire, so that the heating resistance wire generates heat loss and has temperature fluctuation. Meanwhile, the temperature of the air flow is increased by absorbing the heat of the heating resistance wire, so that the sucked air is uncomfortable to a user due to overhigh temperature.
Referring to fig. 1, 2 and 3, in the atomizer 10 of the above embodiment, since the heating element 200 and the atomizing surface 120 are spaced apart from each other, heat generated by the heating element 200 is radiated onto the atomizing surface 120 by infrared rays, so that the atomizing surface 120 absorbs the heat to increase the temperature, thereby effectively preventing the entire heating element 200 from being directly attached to the atomizing surface 120. So can form several following beneficial effects at least:
first, the heating assembly 200 is spaced from the atomization surface 120, so that the heating assembly 200 is prevented from contacting the atomization surface 120, and the heating assembly 200 is prevented from occupying a partial area of the atomization surface 120. The total area of the atomizing surface 120 is the effective area of the atomizing area, so that the effective area of the atomizing area is greatly increased, the atomizing amount of the atomizing medium and the concentration of the aerosol in unit time are increased, and finally, the user experience is improved. Meanwhile, the atomization surface 120 is a curved surface structure, and compared with the atomization surface 120 which has the same area and is in a flat state, the atomization surface 120 is actually in a winding state, so that the installation space occupied by the atomization surface 120 is greatly reduced, and the atomizer 10 is more compact in structure.
Secondly, heating element 200 can not produce physics and chemical reaction with the atomizing medium on the atomizing face 120 with atomizing medium direct contact, prevents that heating element 200 from producing at high temperature with atomizing medium, avoids the interior heavy metal element of heating element 200 to get into the aerosol in order to be absorbed by the user, improves the security that atomizer 10 used. Meanwhile, the atomized medium is separated from the heating assembly 200, so that the atomized medium is prevented from absorbing heat during atomization to reduce the heating temperature of the heating assembly 200, fluctuation of the heating temperature of the heating assembly 200 is avoided, and the temperature of the heating assembly 200 is ensured to be kept consistent all the time so as to improve the smoking taste of aerosol.
Thirdly, the heat on the heating element 200 is transmitted to the atomization surface 120 through the infrared radiation, and compared with the heat through the conduction, the chance that each region absorbs heat on the atomization surface 120 is more equal, ensuring the heat evenly distributed on the atomization surface 120, so that the temperature on the atomization surface 120 is kept consistent, preventing local high temperature and local low temperature on the atomization surface 120, and avoiding the generation of scorched smell and large granular substances influencing the suction taste. Meanwhile, the width of the gap 130 is uniformly set, so that the uniformity of the heat absorption opportunity of the atomization surface 120 can be further improved, the uniformity of the heat distribution on the atomization surface 120 is improved, and the local high temperature of the atomization surface 120 is prevented.
Fourthly, the heat insulator 210 is accommodated in the accommodating cavity 110, the infrared heating body 220 is concealed in the heat insulator 210, and the atomization surface 120 is arranged around the infrared heating body 220, so that most of heat generated by the infrared heating body 220 is absorbed by the atomization surface 120, the heat radiation to the space outside the atomization surface 120 is prevented, the utilization rate of energy is prevented from being influenced, and the atomization amount and aerosol concentration of the atomization medium in unit time are improved. Meanwhile, the heating assembly 200 is disposed around the atomizing surface 120, and the heat insulator 210 or the reflector corresponding to the heating assembly 200 may be omitted, thereby simplifying the structure of the atomizer 10.
Finally and most importantly:
fifthly, the heat insulator 210 has good heat insulation performance, when the gas flows through the gap 130, the gas cannot directly contact with the infrared heating body 220 to absorb the heat thereof, thereby effectively avoiding the heating temperature fluctuation of the infrared heating body 220 caused by the heat absorption of the gas, and further ensuring the temperature of the infrared heating body 220 to be kept constant. Meanwhile, the heat insulation performance of the heat insulator 210 makes the temperature on the outer surface 213 thereof far lower than that of the infrared heating body 220, and the gas flowing through the gap 130 is difficult to absorb heat from the outer surface 213 to increase the temperature, thereby preventing the sucked gas from generating discomfort for the user due to too high temperature. Moreover, the heat insulator 210 and the gas flowing through the space 130 are difficult to absorb the heat of the infrared heating body 220, so that most of the heat generated by the infrared heating body 220 is radiated to the atomization surface 120, thereby improving the energy utilization rate of the infrared heating body 220 and the whole atomizer 10.
The utility model also provides an electronic atomization device, which comprises a power supply assembly and the atomizer 10, wherein the atomizer 10 is arranged on the power supply assembly, and the lower end of the electrode 300 is electrically connected with the power supply assembly, so that the power supply assembly supplies power to the infrared heating body 220 through the electrode 300.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
