Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully 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, an electronic atomizing device according to an embodiment of the present invention includes an atomizer 10 and a power supply, where the atomizer 10 includes a suction nozzle 20 and an atomizing core 30, a liquid storage cavity 21 and an air flow channel 22 are formed in the suction nozzle 20, and the liquid storage cavity 21 is used for storing liquid. The atomizing core 30 is located in the airflow channel 22, and the atomizing core 30 absorbs the liquid stored in the liquid storage cavity 21 to atomize the liquid to form a smokable aerosol, which is substantially an aerosol. The air flow passage 22 extends through the surface (upper end surface) of the mouthpiece 20 to form a mouthpiece 22c, and when the liquid is atomized by the atomizing core 30 to form an aerosol discharged into the air flow passage 22, a user can touch the mouthpiece 22c to suck the aerosol in the air flow passage 22. The power includes electric conductor 40, and electric conductor 40 can be for the electrically conductive post of column structure, and electric conductor 40 and atomizing core 30 electric connection for the power passes through electric conductor 40 and supplies power to whole atomizing core 30, and atomizing core 30 converts the electric energy into the required heat energy of liquid atomization.

Referring to fig. 2, 3 and 4 together, in some embodiments, the atomizing core 30 includes a base 100, a heating body 200, an electrode body 300 and a connector 400. The substrate may be made of porous glass, porous ceramic, honeycomb ceramic, etc., in this embodiment, the substrate 100 is made of a porous ceramic material, that is, the substrate 100 is made of a porous ceramic material, for example, the substrate 100 may be made of alumina, silica, silicon nitride, silicate, or silicon carbide, etc., so that a large number of micropores exist in the substrate 100 and have a certain porosity, the porosity is defined as a percentage of a volume of pores in the object to a total volume of the material in a natural state, a value of the porosity of the substrate 100 may be 20% to 80%, for example, a specific value of the porosity may be 20%, 40%, 50%, or 80%. The average pore diameter of the micropores in the substrate 100 may range from 20 μm to 55 μm, for example, the pore diameter is specifically 20 μm, 30 μm, 45 μm, or 55 μm. The substrate 100 may be formed by a process such as slip casting or powder compression molding, and the substrate 100 may have a cylindrical shape or a prismatic shape, and referring to fig. 5, 6 and 7, when the substrate 100 has a prismatic shape, the substrate 100 may have a rectangular parallelepiped shape.

When the base body 100 is in contact with the liquid in the liquid storage cavity 21, the base body 100 forms a capillary action due to the existence of the micropores, and the liquid can gradually permeate into the base body 100 through the capillary action, so that the base body 100 has a certain buffer function on the liquid. The flow resistance of the liquid penetrating the matrix 100 is inversely proportional to both the porosity and the average pore size of the micropores, and the higher the porosity and the average pore size of the matrix 100, the lower the flow resistance of the liquid in the matrix 100. And the matrix 100 made of the porous ceramic material has good high temperature resistance, and prevents the liquid buffered in the matrix 100 from generating chemical reaction with the matrix 100 under high temperature condition, so that the liquid is wasted because of not participating in unnecessary chemical reaction, and simultaneously avoids various harmful substances generated by the chemical reaction.

Referring to fig. 1, 2 and 5, in some embodiments, the base 100 has a heating surface 110 and a mounting surface 120, the heating surface 110 can absorb heat to raise the temperature, so as to atomize the liquid, and the mounting surface 120 cannot atomize the liquid, so that the heating surface 110 and the mounting surface 120 are two different surfaces. The heat-generating surface 110 and the mounting surface 120 are spaced apart in the extending direction (i.e., vertical direction) of the airflow passage 22, and the heat-generating surface 110 and the mounting surface 120 are oriented just opposite to each other, in which case the heat-generating surface 110 is oriented toward the nozzle opening 22c and is disposed away from the power supply, i.e., the heat-generating surface 110 is disposed upward; and the mounting surface 120 is disposed facing away from the nozzle opening 22c toward the power source, i.e., the mounting surface 120 is disposed facing downward. In general, the heat generating surface 110 is an upper surface of the base 100, and the mounting surface 120 is a lower surface of the base 100. In other embodiments, for example, referring to fig. 8, the heat-generating surface 110 is still disposed upward, the mounting surface 120 is located below the heat-generating surface 110, and the mounting surface 120 and the heat-generating surface 110 are both disposed upward. Both can of course also be arranged downwards.

The heating element 200 may be a metal heating element or an alloy heating element, that is, the heating element 200 may be made of a metal material or an alloy material. The alloy material can be selected from iron-chromium alloy, iron-chromium-aluminum alloy, iron-chromium-nickel alloy, titanium alloy, stainless steel alloy or Cama alloy and the like. The heating element 200 may be formed by a process such as die stamping, casting, mechanical knitting, chemical etching, screen printing, or the like. The base body 100 may be integrally formed with the heating body 200, for example, by removing glue and sintering to obtain an integrally formed structure. Of course, the base 100 and the heating element 200 may be formed separately, for example, the base 100 is formed first, and then the heating element 200 is connected to the base 100 by screen printing, glue removal and sintering.

The heating element 200 may have a long strip-shaped sheet structure, and the heating element 200 may be bent to form various regular or irregular patterns, for example, the heating element 200 may have an S-shape. The heating element 200 is disposed on the heating surface 110, for example, the heating element 200 is directly attached to the heating surface 110, such that the heating element 200 protrudes from the heating surface 110 by a certain height, and for example, a sinking groove may be formed on the heating surface 110, the sinking groove is formed by sinking a part of the heating surface 110 by a set depth, the heating element 200 is embedded in the groove 111, such that the upper surface of the heating element 200 protrudes from the heating surface 110 by a certain height, and the upper surface of the heating element 200 is also flush with the heating surface 110. The thickness of the heating element 200 may range from 0.01mm to 2.00mm, and for example, the thickness may be specifically 0.01mm, 0.03mm, 0.1mm, 2.00mm, or the like. The width of the heat-generating body 200 is in a range of 0.05mm to 3mm, and for example, the width may be specifically 0.05mm, 0.06mm, 0.25mm, 30mm, or the like.

The electrode body 300 is electrically connected to the heating element 200, and the electrode body 300 is also electrically connected to the conductor 40, and the power supply supplies power to the heating element 200 through the conductor 40 and the electrode body 300 in this order. The resistivity of the electrode body 300 is significantly smaller than that of the heating body 200, so that the electrode body 300 has excellent conductive performance. The electrode body 300 may have a sheet structure, the electrode body 300 is disposed on the mounting surface 120, for example, the heating body 200 is directly attached to the heating surface 110, so that the heating body 200 protrudes out of the heating surface 110 by a certain height, and for example, the mounting surface 120 may be provided with a sinking groove formed by recessing a part of the mounting surface 120 by a set depth, the electrode body 300 is embedded in the groove 111, so that the upper surface of the electrode body 300 protrudes out of the mounting surface 120 by a certain height, and the upper surface of the electrode body 300 is also exactly flush with the mounting surface 120. The number of the electrode bodies 300 is two, and one of the electrode bodies 300 is used as a positive electrode, and the other electrode body 300 is used as a negative electrode.

Since the heating element 200 is connected in series with the electrode body 300, the resistivity of the electrode body 300 is significantly smaller than that of the heating element 200, and when the power supply supplies power to the heating element 200, the heating element 200 generates a large amount of heat, and the heating surface 110 absorbs the heat generated by the heating element 200 to raise the temperature, which is sufficient to atomize the liquid. The heat generated by the electrode body 300 is negligible, so that the mounting surface 120 cannot generate a high temperature capable of atomizing the liquid.

If the heating element 200 and the electrode body 300 are simultaneously arranged on the heating surface 110, on one hand, the electrode body 300 occupies a partial area of the heating surface 110, which results in that the effective atomization area on the heating surface 110, which can atomize the liquid, is reduced, that is, the effective atomization area is compressed, thereby reducing the atomization amount of the heating surface 110 to the liquid per unit time and reducing the concentration of smoke; it also results in a slower rate of smoke generation at the heating surface 110, thereby affecting the sensitivity of the atomizing core 30 to the puff response. On the other hand, the electrode body 300 and the conductive columns can absorb heat on the heat receiving and transmitting surface 110, so that the connection failure phenomenon is caused by high temperature of the electrode body 300 and the conductive body 40, and the service life of the atomizing core 30 is influenced; it also causes a large amount of heat loss from the heat generating surface 110, thereby affecting the thermal efficiency of the heat generating surface 110.

In the above embodiment, the heating element 200 is disposed on the heating surface 110, and the electrode body 300 is disposed on the mounting surface 120, that is, the heating element 200 and the electrode body 300 are disposed on different surfaces of the base body 100, so that the electrode body 300 and the heating element 200 are prevented from being located on the same heating surface 110. Therefore, the electrode body 300 can be prevented from invading the partial area of the heating surface 110, so that the heating surface 110 is ensured to maintain an effective atomization area which can atomize the liquid, the atomization amount of the heating surface 110 to the liquid in unit time is increased, and the concentration of smoke is increased; the rate at which the heating surface 110 generates smoke is also increased, thereby increasing the sensitivity of the atomizing core 30 to the puff response. Furthermore, it is possible to prevent connection failure of the electrode body 300 and the conductive post due to heat absorption of the heat receiving and emitting surface 110, to improve the service life of the atomizing core 30, and to reduce heat loss of the heat emitting surface 110 to improve the heat efficiency of the heat emitting surface 110.

Referring to fig. 4 and 7 together, in some embodiments, the base 100 further includes a liquid absorption surface 131, the liquid absorption surface 131 is connected between the heat generation surface 110 and the mounting surface 120, and when the heat generation surface 110 is the upper surface of the base 100 and the mounting surface 120 is the lower surface of the base 100, the liquid absorption surface 131 is actually a portion of the side surface 130 of the base 100. Referring to FIG. 1, the liquid-absorbing surface 131 is adapted to contact liquid in the liquid storage chamber 21, and the liquid contacting the liquid-absorbing surface 131 can permeate into the interior of the base 100 by capillary action.

Referring to fig. 2, 3 and 4, the connecting members 400 are connected between the electrode bodies 300 and the heating elements 200, the number of the connecting members 400 is two, the upper end of one of the connecting members 400 is electrically connected to one end of the heating element 200 and the lower end thereof is electrically connected to one of the electrode bodies 300, and the upper end of the other connecting member 400 is electrically connected to the other end of the heating element 200 and the lower end thereof is electrically connected to the other electrode body 300. The connector 400 may be made of the same material as the heating element 200, or may be integrally formed. The base 100 is further provided with a through hole 101, the through hole 101 extends along the installation direction and simultaneously penetrates through the heating surface 110 and the installation surface 120, and the connecting body 400 is matched with the installation through hole 101, so that the whole connecting body 400 is arranged inside the base 100 in a penetrating manner.

Since the connector 400 is inserted into the base 100, on one hand, the stability of the connector 400 can be improved, and the heating element 200 can be firmly fixed on the heating surface 110; the connection strength between the connector 400 and the electrode body 300 can be increased, and the stability and reliability of both the connector 400 and the electrode body 300 in terms of mechanical connection and electrical connection can be ensured. On the other hand, when the connecting body 400 is powered on, the connecting body 400 generates a certain amount of heat, thereby playing a certain preheating role on the base body 100, reducing the viscosity of the liquid buffered in the base body 100 due to heat absorption, further improving the fluidity of the liquid in the base body 100, namely reducing the flow resistance of the liquid, enabling the liquid to quickly reach the heating surface 110 from the liquid absorption surface 131 through the inside of the base body 100 for atomization, avoiding the dry burning phenomenon, and ensuring that the whole atomization core 30 can meet the atomization requirement on the high-viscosity liquid.

Further, the distance between the connector 400 and the liquid-absorbent surface 131 is smaller than the distance between the connector 400 and the geometric center of the base 100, and in colloquial, the connector 400 is disposed closer to the liquid-absorbent surface 131. At this time, the region of the base body 100 close to the liquid absorption surface 131 is enabled to rapidly absorb heat to improve the fluidity of the liquid, ensuring that the liquid rapidly enters the inside of the base body 100 from the liquid storage chamber 21 through the liquid absorption surface 131.

In other embodiments, the connection body 400 and the heating element 200 may be made of different materials, and referring to fig. 8, the connection body 400 may be directly attached to the outer surface of the base 100 without being inserted into the base 100.

Referring to fig. 1, if the heat generating surface 110 is disposed opposite to the nozzle opening 22c and faces the power supply, the whole atomizing core 30 divides the airflow channel 22 into two parts, the part of the airflow channel 22 above the atomizing core 30 is referred to as an upper channel 22a, and the part of the airflow channel 22 below the atomizing core 30 is referred to as a lower channel 22 b. Also, the electrical conductor 40 is also located in the lower channel 22 b. When the heat generating body 200 is operated, the mist generated on the heat generating surface 110 will first enter the lower passage 22b, then pass through the portion of the air flow passage 22 between the atomizing core 30 and the suction nozzle 20 to enter the upper passage 22a, and finally be absorbed by the user through the nozzle opening 22 c. This design mode may be referred to simply as "downward atomization mode".

The above-mentioned "downward atomization mode" has at least the following four drawbacks: one is that the smoke is first discharged into the lower channel 22b, and the conductive body 40 occupies a part of the space in the lower channel 22b, so that the total space of the lower channel 22b is compressed and reduced, resulting in unfavorable for sufficient atomization of the liquid. Secondly, the smoke discharged into the lower channel 22b will contact with the electric conductor 40, and the electric conductor 40 will block the circulation and transmission of the smoke, and influence the transmission speed of the smoke in the airflow channel 22. Thirdly, the smoke generated on the heating surface 110 reaches the suction opening 22c through a longer path, so that the probability of the smoke condensing into large particle droplets in the airflow channel 22 is increased, the concentration is reduced due to smoke loss, and the large particle droplets are also caused to block the airflow channel 22 or leak to the power supply to corrode the power supply. If it is desired to reduce aerosol condensation, there will be greater demands on the structural design of the entire airflow passageway 22, thereby increasing the design and manufacturing costs of the entire electronic atomizer device. Fourthly, the liquid tends to gather on the heating surface 110 under the action of gravity, and in the case that the viscosity of the liquid itself is low, the liquid gathered on the heating surface 110 is dropped to separate from the atomizing core 30, thereby causing the leakage of the liquid.

Referring to fig. 1, in the above embodiment, the heat generating surface 110 is disposed toward the nozzle opening 22c (i.e., disposed upward), and the mounting surface 120 is disposed away from the nozzle opening 22c and toward the power source (i.e., disposed downward), such that the conductive body 40 is located at a side where the mounting surface 120 is located, i.e., the conductive body 40 is located in the lower passage 22 b. When the heating body 200 is operated, the fumes generated on the heating surface 110 directly enter the upper passage 22a, rather than being discharged to the lower passage 22 b. This design mode may be referred to simply as "upward atomization mode".

The above-mentioned "upward atomization mode" has at least the following four beneficial effects: one is that the smoke is discharged directly into the upper channel 22a, the electrical conductor 40 located in the lower channel 22b obviously does not occupy the space of the upper channel 22a, so that the space of the upper channel 22a is large enough to facilitate adequate atomization of the liquid. Secondly, the smoke is directly discharged into the upper channel 22a, and the electric conductor 40 in the lower channel 22b obviously cannot be contacted with the smoke in the upper channel 22a, so that the blocking of the electric conductor 40 to the smoke is effectively avoided, and the circulation speed of the smoke in the airflow channel 22 is improved. Third, the smoke generated on the heating surface 110 directly reaches the suction nozzle 22c through the upper channel 22a to be absorbed by the user, so that the flow path of the smoke from the lower channel 22b to the upper channel 22a is eliminated, the path length of the smoke flowing through the smoke reaching the suction nozzle 22c is reduced, the probability of the smoke condensing in the airflow channel 22 to form large-particle droplets is reduced, the concentration reduction caused by smoke loss is prevented, and the large-particle droplets are effectively prevented from blocking the airflow channel 22 or leaking to the power supply to corrode the airflow channel 22. Meanwhile, the requirement of the air flow channel 22 on the structural design can be properly reduced, so that the design and manufacturing cost of the whole electronic atomization device is reduced. And fourthly, the liquid is gathered upwards to the heating surface 110 against the gravity, thereby reducing the possibility of the liquid dropping and separating from the atomizing core 30 to cause leakage.

Referring to fig. 1 and 2, in some embodiments, the base 100 further has air holes 102, and the air holes 102 penetrate through the mounting surface 120 and the heating surface 110. When a user draws on the nozzle 22c, air can pass from the lower channel 22b through the air-guide holes 102 into the upper channel 22a so that the air carries the smoke to the nozzle 22 c. The aperture of the air vent 102 ranges from 0.05mm to 5.00mm, for example, the aperture of the air vent 102 may specifically be 0.05mm, 1mm, 4mm, or 5 mm. The number of the air holes 102 may be one or more, and the air holes 102 may be circular holes, elliptical holes, regular polygonal holes, or the like. The mounting surface 120 and the heat generating surface 110 may be two planes parallel to each other, and of course, the mounting surface 120 and the heat generating surface 110 may also be curved.

In some embodiments, the mounting surface 120 is formed with a groove 111, and the groove 111 is recessed toward the heat generating surface 110 by a predetermined depth. By providing the grooves 111, the total weight of the atomizing core 30 can be reduced, and the flow resistance of the liquid in the base body 100 can be reduced, so that the liquid can reach the heat generating surface 110 from the liquid absorbing surface 131 quickly.

Referring to fig. 9 and 10, the base 100 may further include a base portion 140 and a boss portion 150, the base portion 140 has a step surface 141, the mounting surface 120 is located on the base portion 140, and the mounting surface 120 and the step surface 141 face opposite directions, that is, the step surface 141 faces upward, and the mounting surface 120 faces downward. The boss portion 150 is connected to the stepped surface 141, the boss portion 150 protrudes by a certain height with respect to the stepped surface 141, and the heating surface 110 is located on the boss portion 150 such that the heating surface 110 is disposed upward. The stepped surface 141 and the boss portion 150 can provide a good stopper effect to the entire base body 100 when the base body 100 is mounted on the suction nozzle 20, improving the stable reliability of the mounting of the atomizing core 30.

In some embodiments, both the nebulizer 10 and the power source are removably connected. When the atomizer 10 is a disposable consumable, the atomizer 10 after use can be conveniently unloaded from the power supply and discarded separately, and the power supply can be used in combination with a new atomizer 10 to realize recycling.

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.
