Detailed Description
To facilitate an understanding of the utility model, the utility model 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 figures 1, 2 and 3, an electronic atomisation device according to an embodiment of the utility model comprises a heater 10 and a power supply assembly, the heater 10 being interposed within a solid aerosol-generating substrate, the heater 10 converting electrical energy to thermal energy when the power supply assembly supplies power to the heater 10, the aerosol-generating substrate absorbing heat from the heater 10 and being atomised to form an aerosol, the aerosol being substantially an aerosol for inhalation by a user. The heater 10 includes heating bodies 100, two electrode bodies 200, lead wires 300, and a mount 400, the number of the electrode bodies 200 being two, the heating body 100 being sandwiched between the two electrode bodies 200.
In some embodiments, heating body 100 includes tip portion 110 and main body portion 120, tip portion 110 is attached to one end of main body portion 120, and the cross-sectional size of main body portion 120 can be maintained constant. The cross-sectional dimension of the tip portion 110 in the reference direction is gradually reduced with the direction of the main body portion 120 toward the tip portion 110 as the reference direction. By providing the tip 110, the resistance to insertion of the entire heater 10 into the aerosol-generating substrate may be reduced, and bending or even breaking of the heater 10 in the event of excessive resistance may be avoided, which may improve the useful life of the heater 10. Heating body 100 may have a columnar structure, for example, main body 120 may have a substantially cylindrical shape, tip 110 may have a substantially conical shape, and cylindrical main body 120 may have a diameter of 1mm to 4 mm. The heating body 100 may also have a sheet structure, and the length of the heating body 100 having the sheet structure may be about 19mm, the width thereof may be about 4.5mm, and the thickness thereof may be about 0.4 mm.
The resistivity of the heating body 100 may range from 5 × 10-3M to 2 x 10-1Omega, m. For example, when the heating body 100 has a columnar structure, the resistivity of the heating body 100 may range from 5 × 10-3M to 2 x 10-2Omega, m. When the heating body 100 has a sheet structure, addThe thermal body 100 may have a resistivity in the range of 2 x 10-2M to 2 x 10-1Omega, m. To meet the above-mentioned resistivity requirement, heater 100 is made of a mixture of a material having a relatively high resistivity and a material having a relatively low resistivity, for example, heater 100 is made of Ni metal and Al2O3Ceramic, Cr2C3Ceramics or NiFe2O4The metal composite ceramic body formed by compounding the ceramics can ensure that the heating body 100 has a reasonable temperature coefficient of resistivity on the basis of meeting the requirement of resistivity. Therefore, the real-time temperature of the heating element can be accurately obtained by detecting the resistance of the heating element on the basis of the reference resistivity temperature coefficient, and the temperature of the heating element 100 is ensured to be in a reasonable interval all the time.
In some embodiments, the resistivity of electrode body 200 is smaller than that of heater 100, so that electrode body 200 has more excellent conductive properties than heater 100. The electrode body 200 may be made of a metal material such as Ag, Cu, Au, or Ni. The electrode body 200 may be integrally connected to the heating body 100 through a screen printing, sintering, vapor deposition, or other process, so that an adhesive layer between the electrode body 200 and the heating body 100 may be omitted, the manufacturing cost of the heater 10 may be reduced, and the connection strength between the electrode body 200 and the heating body 100 may be improved. Since the heating body 100 is sandwiched between the electrode bodies 200, when a voltage is applied between the two electrode bodies 200, a current can flow from one of the electrode bodies 200 to the other electrode body 200 in a direction perpendicular to the length direction of the heating body 100, i.e., a direction indicated by a dotted arrow in fig. 4 is a current direction. During the passage of an electric current through the heating body 100, which is sandwiched between the two electrode bodies 200, the heating body 100 generates heat due to its electrical resistance, so that the aerosol-generating substrate absorbs this heat to atomize and form an aerosol.
The length of electrode body 200 may be less than the length of heating body 100, so that partial heating body 100 cannot be covered by electrode body 200, and obviously, the portion of heating body 100 that can be covered by electrode body 200 generates heat due to the presence of current, and the portion of heating body 100 that is not covered by electrode body 200 cannot generate heat due to the absence of current. Therefore, along the length direction of the heater 10, the section of the heater 10 covered with the electrode body 200 forms a heating section capable of generating heat by itself, and the section of the heater 10 not covered with the electrode body 200 is a non-heating section which cannot generate heat by itself but can only absorb heat of the heating section. Thus, the heating section of the heater 10 may be fully inserted into the aerosol-generating substrate so that the heat generated by the heating section is largely directly available to the aerosol-generating substrate, thereby increasing the efficiency of the heater 10 with respect to energy, while the non-heating section of the heater 10 is located outside the aerosol-generating substrate.
If the heater 10 adopts a mode in which the resistive circuit heats the ceramic substrate, there are disadvantages in that the connection process of the resistive circuit and the ceramic substrate is complicated, and the production efficiency and yield of the heater 10 are low. Secondly, the ceramic substrate is not conductive, that is, the ceramic substrate itself cannot generate heat, and the ceramic substrate can only absorb the heat generated by the resistance circuit to heat the aerosol generating substrate. On one hand, the resistance circuit generates heat loss in the heat transfer process, and the energy utilization rate of the heater 10 is influenced; on the other hand, the ceramic substrate heats up at a slower rate, resulting in a longer wait time for the heater 10 to elapse from the start of operation to the atomisation of the aerosol-generating substrate, i.e. there is a longer delay in atomisation of the aerosol-generating substrate, thereby affecting the sensitivity of the heater 10 to the user's puff response.
If the heating body 100 of the heater 10 is conductive to generate heat, it is generally known that in order to prevent the heating body 100 from short-circuiting, a through groove is formed in the heating body 100, which increases the manufacturing process of the groove, thereby complicating the manufacturing process of the heater 10 and increasing the manufacturing cost, and which reduces the structural strength of the heater 10, and the heater 10 may be bent or broken due to the insertion resistance during the insertion into the aerosol-generating substrate, thereby reducing the lifespan of the heater 10.
With the heater 10 in the above embodiment, by interposing the heating body 100 between the two electrode bodies 200, it is possible to simplify the manufacturing process of the heater 10, improve the production efficiency of the heater 10, and reduce the manufacturing cost thereof. Secondly, the formation of a through groove on the heating body 100 can be effectively avoided, thereby improving the structural strength of the heater 10, preventing the heater 10 from being damaged in the process of being inserted into the aerosol generating substrate, and prolonging the service life of the heater 10. Thirdly, the heating body 100 itself can conduct electricity to generate heat without absorbing the heat in a conduction manner, so that on one hand, heat loss generated in the conduction process of the heat can be avoided, and the energy utilization rate of the heater 10 is improved; on the other hand, the heater 10 itself generates heat and heats up quickly, greatly reducing the latency time it takes for the heater 10 to operate until it atomises the aerosol-generating substrate, and increasing the sensitivity of the heater 10 to the user's puff response.
Referring to fig. 5 and 6, in some embodiments, the width of electrode body 200 in the flattened state is non-uniformly arranged along the length direction of heating body 100, so-called "flattened state", i.e., electrode body 200 is unfolded into a planar state. For example, each electrode body 200 includes a first electrode portion 210 and a second electrode portion 220 connected to each other, the first electrode portion 210 and the second electrode portion 220 are both located on the main body portion 120, the first electrode portion 210 is closer to the tip portion 110 than the second electrode portion 220, and the width of the first electrode portion 210 is larger than the width of the second electrode portion 220 in the flattened state. Considering that the width of the first electrode portions 210 is greater than the width of the second electrode portions 220, the portion of the heating body 100 sandwiched between the two first electrode portions 210 generates a large current and has a high temperature, and the portion of the heating body 100 sandwiched between the two second electrode portions 220 generates a small current and has a low temperature, so that the heat field and the temperature field of the entire heater 10 exhibit a distribution rule with a certain gradient. For example, it may be ensured that the warmer portion of the heater 10 is wholly inserted within the aerosol-generating substrate, thereby improving the efficiency of the heater 10. In other embodiments, when heating body 100 is of a columnar structure, the dimension occupied by electrode bodies 200 in the circumferential direction of heating body 100 is non-uniformly arranged along the length direction of heating body 100; when the heating body 100 is a sheet-like structure, the size occupied by the electrode bodies 200 in the width direction of the heating body 100 is non-uniformly arranged along the length direction of the heating body 100.
In some embodiments, the electrode body 200 further comprises a third electrode portion 230, the third electrode portion 230 being located on the main body portion 120, the second electrode portion 220 being connected between the first electrode portion 210 and the third electrode portion 230 such that the third electrode portion 230 is further away from the tip portion 110 relative to the second electrode portion 220. In the flattened state, the width of the third electrode portion 230 is greater than the width of the second electrode portion 220. The number of the lead wires 300 is two, each lead wire 300 may be connected to a different third electrode part 230, and in view of the fact that the width of the third electrode part 230 is greater than the width of the second electrode part 220, the connection strength between the lead wires 300 and the third electrode part 230 may be improved.
In some embodiments, referring to fig. 2, when the heating body 100 has a sheet-like structure, the electrode body 200 may further include a fourth electrode portion 231, the fourth electrode portion 231 being disposed at the tip portion 110 and connected to an end of the first electrode portion 210, the fourth electrode portion 231 having a cross-sectional size that gradually decreases with reference to a direction in which the main body portion 120 is directed toward the tip portion 110. This makes it possible to adapt the shape of the tip portion 110 to the fourth electrode portion 231, so that the fourth electrode portion 231 can be smoothly mounted.
The other end of the lead 300 extends from the connection with the electrode body 200 by a set length in the reference direction, which is the direction in which the tip portion 110 is directed toward the main body portion 120. In general, leads 300 are located at the same end (i.e., the lower end) of heater body 100 and extend away from tip portion 110. In other embodiments, leads 300 may be located at opposite ends of heater body 100.
In some embodiments, referring to fig. 7, for example, the electrode body 200 is embedded in the heating body 100, and the surfaces of the electrode body 200 and the heating body 100 are flush with each other, so that the surface of the entire heater 10 is in a smooth transition state, and the resistance of the heater 10 during the insertion process is reduced. Referring to fig. 8, for another example, when the heating body 100 is in a cylindrical shape, the heating body 100 has a first plane 140 and a first arc surface 150 that are connected to each other, the electrode body 200 has a second plane 240 and a second arc surface 250, and the second arc surface 250 is connected to two opposite ends of the second plane 240, so that the second plane 240 and the second arc surface 250 are connected to form a closed loop structure. When the second plane 240 is attached to the first plane 140, the tangent planes at the connection positions of the first arc surface 150 and the second arc surface 250 are overlapped, so that smooth transition between the first arc surface 150 and the second arc surface 250 can be ensured, and the insertion resistance of the heater 10 can be reduced.
Referring to fig. 1, in some embodiments, a mounting seat 400 is sleeved outside heating body 100, and obviously, the cross-sectional size of mounting seat 400 is larger than that of heating body 100. By providing the mounting seat 400, the entire heater 10 can be fixed to the power module via the mounting seat 400. The heater 10 may further include a glaze layer attached to the surfaces of the electrode body 200 and the heating body 100. Through the glaze layer, on one hand, the viscous substances generated by the aerosol generating substrate in the heating and atomizing process can be prevented from corroding the heating body 100 and the electrode body 200, on the other hand, the surface of the glaze layer is smoother, and the viscous substances can be effectively prevented from being adhered to the glaze layer, so that the cleanliness of the heater 10 is improved.
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.
