Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Referring to fig. 1 to 5, an atomizer according to an embodiment of the present invention will now be described. The atomizer provided by the embodiment of the utility model is suitable for the atomizer of an aerosol generating device, and the atomizer atomizes aerosol forming substrates to form smoke through the atomizer so as to be sucked by a user to achieve the effect of simulating smoking. Referring to fig. 1, 2 and 3, an atomizer provided in an embodiment of the present invention includes a base 1, an upper cover 2, a liquid guiding member 3 and a heating wire 4, wherein an atomizing tank 11 is recessed on a top end surface of the base 1, and the upper cover 2 covers a notch of the atomizing tank 11 and closes the notch of the atomizing tank 11, so that an atomizing chamber 12 for heating and atomizing aerosol-forming substrate is formed inside the base 1. First feed liquor hole 13 and second feed liquor hole 14 have been seted up on the lateral wall of base 1, and first feed liquor hole 13 sets up with second feed liquor hole 14 relatively, and just first feed liquor hole 13 with the stock solution chamber 53 intercommunication of atomizing chamber 12 and atomizer, second feed liquor hole 14 with the stock solution chamber 53 intercommunication of atomizing chamber 12 and atomizer. The liquid guiding member 3 is disposed in the atomizing chamber 12, a first end 31 of the liquid guiding member 3 extends into the first liquid inlet hole 13, and a second end 32 of the liquid guiding member 3 extends into the second liquid inlet hole 14. It is understood that the fluid-conducting member 3 can be, but is not limited to, a fluid-conducting body made of a porous fluid-conducting medium material such as porous ceramic. The heating wire 4 is arranged in the atomizing cavity 12, and the heating wire 4 is spirally wound on the liquid guide member 3. Referring to fig. 4 and 5, the resistance of the portion of the heating wire 4 close to the first liquid inlet hole 13 is smaller than the resistance of the middle portion of the heating wire 4, and the resistance of the portion of the heating wire 4 close to the second liquid inlet hole 14 is smaller than the resistance of the middle portion of the heating wire 4, so that the areas where the portions of the heating wire 4 close to the two ends of the heating wire 4 are respectively formed into the low-temperature preheating areas 30 for preheating the aerosol-forming substrate when the heating wire is powered on to generate heat, and the areas where the middle portion of the heating wire 4 is formed into the high-temperature atomizing areas 40 for heating and atomizing the preheated aerosol-forming substrate when the heating wire is powered on to generate heat.
When the atomizer is in operation, the two ends of the liquid guiding member 3 (the first end 31 of the liquid guiding member 3 and the second end 32 of the liquid guiding member 3) respectively absorb aerosol-forming substrates from the liquid storage chamber 53 of the atomizer, and the aerosol-forming substrates absorbed by the two ends of the liquid guiding member 3 respectively flow towards the middle part of the liquid guiding member 3. Because the heating wire 4 is spirally wound on the liquid guide member 3, the resistance of the part of the heating wire 4 close to the first liquid inlet hole 13 is smaller than that of the middle part of the heating wire 4, and the resistance of the part of the heating wire 4 close to the second liquid inlet hole 14 is smaller than that of the middle part of the heating wire 4. It can be understood that, since the resistance value of the middle portion of the heating wire 4 is greater than the resistance values of the two side portions of the middle portion, and the currents flowing into the heating wire 4 are equal, the formula P ═ I is calculated according to the heating power of the resistor2And multiplying the obtained product by the multiplied by R to obtain the heating power of the resistance wire. Therefore, when the heating wire 4 is energized to generate heat, the heating power of the portions of the heating wire 4 near the two ends thereof is small, and the heating power of the middle portion of the heating wire 4 is large, so that the low-temperature preheating region 30 for preheating the aerosol-forming substrate can be formed in the region where the portions of the heating wire 4 near the two ends are located, and the high-temperature atomizing region 40 for heating and atomizing the preheated aerosol-forming substrate can be formed in the region where the middle portion of the heating wire 4 is located. In the process that the aerosol-forming substrate flows from the two ends of the liquid guide piece 3 to the middle position of the liquid guide piece 3, the aerosol-forming substrate is preheated in the low-temperature preheating zone 30 at first, and the preheated aerosol-forming substrate is heated and atomized in the high-temperature atomizing zone 40, so that the aerosol-forming substrate is heated and heated gradually, the phenomenon that the aerosol-forming substrate is fried by being heated to high temperature instantly and directly from low temperature is avoided, the atomizing effect of the atomizer on the aerosol-forming substrate is improved, and the experience of a user using the aerosol generating device is further improved.
It is to be understood that the low temperature in the embodiments of the present invention is relative to the high temperature in the embodiments of the present invention. That is, the high temperature in embodiments of the utility model refers to the temperature required to heat and atomise the aerosol-forming substrate instantaneously, and the low temperature in embodiments of the utility model refers to any temperature between ambient temperature and the high temperature in embodiments of the utility model. However, in view of the good effect of avoiding the occurrence of frying oil, the low temperature in the embodiment of the present invention may generally be a preset temperature that is much higher than the normal temperature and much lower than the high temperature in the embodiment of the present invention, and the temperature may preheat the aerosol-forming substrate to a certain temperature, but is not enough to instantaneously heat and atomize the aerosol-forming substrate, thereby achieving the effect of gradually heating and raising the temperature of the aerosol-forming substrate.
Compared with the prior art, the atomizer provided by the embodiment of the utility model has the advantages that the heating wire 4 is spirally wound on the liquid guide piece 3, when the heating wire 4 is electrified to generate heat, the areas of the parts of the heating wire 4 close to the two ends form the low-temperature preheating area 30 for preheating the aerosol-forming substrate, and the area of the middle part of the heating wire 4 forms the high-temperature atomizing area 40 for heating and atomizing the preheated aerosol-forming substrate. In the process that the aerosol-forming substrate is guided to the heating wire 4 through the two ends of the liquid guide piece 3, the aerosol-forming substrate is preheated in the low-temperature preheating zone 30 at first, and the preheated aerosol-forming substrate is heated and atomized in the high-temperature atomization zone 40, so that the aerosol-forming substrate is heated and heated gradually, the phenomenon that the aerosol-forming substrate is fried by low-temperature instant direct heating to high temperature is avoided, the atomization effect of the atomizer on the aerosol-forming substrate is improved, and the experience of a user in using the aerosol generating device is further improved.
Referring to fig. 3, 4 and 5, in some embodiments, the heating wire 4 has a circular longitudinal cross-section, the heating wire 4 includes a first heating section 41, a second heating section 42 and a third heating section 43 sequentially disposed and connected along a direction from the first liquid inlet hole 13 to the second liquid inlet hole 14, a diameter of the first heating section 41 is larger than a diameter of the second heating section 42, so that a resistance of the first heating section 41 is smaller than a resistance of the second heating section 42, and the third heating section 43The diameter of the third heat generation section 43 is larger than that of the second heat generation section 42 so that the resistance of the third heat generation section 43 is smaller than that of the second heat generation section 42. By adopting the above scheme, the heating wire 4 with a cylindrical outline is divided into the first heating section 41, the second heating section 42 and the third heating section 43 which are connected in sequence along the direction from the first liquid inlet hole 13 to the second liquid inlet hole 14, the diameter of the first heating section 41 is set to be larger than that of the second heating section 42, the diameter of the third heating section 43 is set to be larger than that of the second heating section 42, when the length of each heating element is constant and equal, according to a resistance calculation formula R of the cylindrical heating element 4, where ρ represents the resistivity of the heating element 4 and is determined by its own properties, L represents the length of the heating element 4, and S represents the cross-sectional area of the heating element 4, the larger the diameter thereof, the smaller the corresponding resistance value, so that the resistance of the first heat generation section 41 is smaller than the resistance value of the second heat generation section 42, and the resistance of the third heat generation section 43 is smaller than the resistance value of the second heat generation section 42. Of course, it can be understood that, under the condition that the length of the first heat-generating section 41 and the length of the second heat-generating section 42 are certain and unequal, when the diameter of the first heat-generating section 41 is much larger than the diameter of the second heat-generating section 42, and the difference between the lengths of the first heat-generating section 41 and the second heat-generating section 42 is not large or the difference between the lengths is within an allowable range, theoretically, the resistance of the first heat-generating section 41 can also be ensured to be smaller than the resistance of the second heat-generating section 42. That is to say, under the condition that the resistance of the first heating section 41 and the resistance of the second heating section 42 are mainly affected by the diameters thereof (when the diameter of the first heating section 41 is much larger than the diameter of the second heating section 42, and the difference between the lengths of the first heating section 41 and the second heating section 42 is small enough not to affect the resistance of the first heating section 41 and the resistance of the second heating section 42), when the length of the third heating section 43 and the length of the second heating section 42 are certain and unequal, it can be ensured that the resistance of the third heating section 43 is smaller than the resistance of the second heating section 42. Similarly, under the condition that the length of the third heating section 43 is not equal to the length of the second heating section 42, when the diameter of the third heating section 43 is much larger than the diameter of the second heating section 42, and the difference between the length of the third heating section 43 and the length of the second heating section 42 is not large or the difference between the lengths is within the allowable range, it can be theoretically ensured that the third heating section 43 and the second heating section 42 have the same lengthThe resistance of the thermal section 43 is smaller than that of the second heat generation section 42. That is, under the condition that the resistance of the third heat-generating section 43 and the resistance of the second heat-generating section 42 are mainly affected by the diameters thereof (when the diameter of the first heat-generating section 41 is much larger than the diameter of the second heat-generating section 42, the difference between the lengths of the first heat-generating section 41 and the second heat-generating section 42 is small enough not to affect the resistance of the first heat-generating section 41 and the resistance of the second heat-generating section 42), when the length of the third heat-generating section 43 and the length of the second heat-generating section 42 are constant and unequal, the resistance of the third heat-generating section 43 can be ensured to be smaller than the resistance of the second heat-generating section 42. Thus, as long as the resistance of the first heating section 41 is smaller than the resistance of the second heating section 42, and the resistance of the third heating section 43 is smaller than the resistance of the second heating section 42, the formula P ═ I can be calculated according to the above resistance heating power2The xr obtains the heating power of the resistance wire, when the heating wire 4 is electrified to generate heat, the heating power of the first heating section 41 and the third heating section 43 of the heating wire 4 close to the two ends of the heating wire is respectively smaller than the heating power of the second heating section 42 positioned in the middle part of the heating wire 4, so that the low-temperature preheating zone 30 for preheating the aerosol-forming substrate can be respectively formed in the area where the first heating section 41 is positioned and the area where the third heating section 43 is positioned, and the high-temperature atomizing zone 40 for heating and atomizing the preheated aerosol-forming substrate is formed in the area where the third heating section 43 of the heating wire 4 is positioned. In the process that the aerosol-forming substrate flows from the two ends of the liquid guide piece 3 to the middle position of the liquid guide piece 3, the aerosol-forming substrate is preheated in the low-temperature preheating zone 30 at first, and the preheated aerosol-forming substrate is heated and atomized in the high-temperature atomizing zone 40, so that the aerosol-forming substrate is heated and heated gradually, the phenomenon that the aerosol-forming substrate is fried by being heated to high temperature instantly and directly from low temperature is avoided, the atomizing effect of the atomizer on the aerosol-forming substrate is improved, and the experience of a user using the aerosol generating device is further improved.

By adopting the above scheme, the diameter of the first heating section 41 is equal to that of the third heating section 43, so that the resistance of the first heating section 41 is the same as that of the third heating section 43, and under the condition that the lengths of the first heating section 41 and the third heating section 43 are fixed and equal, the heating power of the first heating section 41 is the same as that of the third heating section 43, so that the aerosol-forming substrate positioned at two sides of the second heating section 42 can be uniformly preheated, and the uniformly preheated aerosol-forming substrate flows to the high-temperature atomization zone 40 for heating and atomization, so that the aerosol-forming substrate is gradually heated and heated, and the phenomenon that the aerosol-forming substrate is instantly and directly heated to high temperature from low temperature to generate oil burst is avoided.

Referring to fig. 1, 2 and 3, in some embodiments, the heating wire 4 is wound around the middle position of the liquid guiding member 3, and in the process that the aerosol-forming substrate flows from the two ends of the liquid guiding member 3 to the middle position of the liquid guiding member 3, the aerosol-forming substrate can have sufficient preheating time in the atomizing chamber 12 and the low-temperature preheating region 30, so that the aerosol-forming substrate is gradually heated and heated, and the preheated aerosol-forming substrate is subjected to instantaneous high-temperature heating and atomizing in the high-temperature atomizing region 40 located at the middle position of the liquid guiding member 3, which is beneficial to avoiding the phenomenon that the aerosol-forming substrate is instantaneously and directly heated to high temperature from low temperature to cause oil frying.

Of course, it is understood that, in the case that the amount of the liquid supplied to the heating wire 4 is satisfied, only the first end 31 of the liquid guiding member 3 may pass through the first liquid inlet hole 13 and extend into the liquid storage chamber 53 of the atomizer, or only the second end 32 of the liquid guiding member 3 may pass through the second liquid inlet hole 14 and extend into the liquid storage chamber 53 of the atomizer, and the setting may be properly selected according to the actual use requirement, which is not limited herein.

Referring to fig. 3, in some embodiments, the outline of the liquid guiding member 3 is cylindrical, and the spiral heating wire is sleeved on the cylindrical liquid guiding member 3, so that the heating wire 4 spirally wound on the outer circumferential surface of the cylindrical liquid guiding member 3 is tightly attached to the surface of the liquid guiding member 3, thereby preventing the heating wire 4 from contacting the surface of the liquid guiding member 3 poorly, which may cause dry burning or oil frying. Of course, it is understood that the above embodiment, in which the outer contour of the liquid guiding member 3 is cylindrical, is only a preferred embodiment of the present invention.
