[0035] like Figure 1 and Figure 2 As shown, some embodiments of the present invention provide a heating structure, which is mainly used in an aerosol generating device to improve the uniformity of air heating by the heating element, the heating efficiency and the stability during the heating process.
[0036] The heating structure includes a base 100 , a first wire 400 , a second wire 500 , a first heating element 200 and a second heating element 300 .
[0037] Along the first direction, the base 100 has a first surface 110 and a second surface 120 that are relatively arranged. It should be noted that the first surface 110 is parallel to the second surface 120, so that when the gas flows through the first surface 110 through the second surface 120, the flow path of the gas between the first surface 110 and the second surface 120 is equal, so as to ensure the uniformity of the gas heating by the first heating body 200 and the second heating body 300.
[0038] It should be noted that the first direction mentioned here refers to a direction perpendicular to the first surface 110 and the second surface 120 , that is, a thickness direction of the base 100 .
[0039] The base 100 defines a groove 130 penetrating the first surface 110 , and along the first direction, the notch of the groove 130 faces the side of the first surface 110 away from the second surface 120 .
[0040] In addition, the base 100 is provided with an air flow channel 140 penetrating the second surface 120 , and the air flow channel 140 is communicated with the groove 130 , so that the gas can flow through the air flow channel 140 and the groove 130 in sequence along the first direction.
[0041] In this embodiment, the first heating element 200 is disposed in the groove 130 , so that the gas flowing through the groove 130 is heated by the first heating element 200 .
[0042] Furthermore, there is a gap between the first heating body 200 and the inner wall of the groove 130 to prevent the first heating body 200 from directly conducting heat to the inner wall of the groove 130, thereby ensuring the uniformity of heating the air in the groove 130 by the first heating body 200 and improving the heating quality and stability of the air in the groove 130.
[0043] The heating structure further includes at least one second heating element 300 , that is, the number of the second heating elements 300 can be one, two, or more than two, of any numerical value, which can be specifically set according to actual conditions.
[0044] Specifically, the second heating body 300 is arranged on the side of the first heating body 200 facing the first surface 110, there is a gap between the second heating body 300 and the inner wall of the groove 130, and there is a gap between the first heating body 200 and the second heating body 300 to ensure the uniformity and stability of the second heating body 300 heating the gas.
[0045] The first wire 400 is disposed on the second surface 120 , and one end of the first wire 400 passes through the second surface 120 and is connected to one end of the first heating element 200 and one end of the second heating element 300 .
[0046] That is, one end of the first heating element 200 and one end of the second heating element 300 are respectively connected to the first wire 400 , and the second wire 500 is used to connect to an external power source.
[0047] In addition, the second conductive wire 500 is disposed on the second surface 120 , and along the second direction, the first conductive wire 400 and the second conductive wire 500 are disposed at two ends of the second surface 120 .
[0048] The second direction mentioned here refers to the length direction of the base 100, and the first direction is perpendicular to the second direction.
[0049] Specifically, one end of the second wire 500 passes through the second surface 120 and is connected to one end of the first heating element 200 and the second heating element 300 away from the first wire 400 .
[0050] It can be understood that one end of the first heating element 200 away from the first wire 400 and one end of the second heating element 300 away from the first wire 400 are both connected to the second wire 500 .
[0051] It should be noted that, in this embodiment, the first wire 400 and the second wire 500 are respectively connected to an external power source so that the current of the external power source flows through the first wire 400, through the first heating element 200 and the second heating element 300, and flows through the second wire 500 to form a closed current loop, so that the first heating element 200 and the second heating element 300 generate heat under the thermal effect of the current, thereby heating the gas flowing through the groove 130 through the first heating element 200 and the second heating element 300.
[0052] Specifically, by setting the first heating element 200 and the second heating element 300 spaced apart from each other, when the airflow flows from the airflow channel 140 through the groove 130 along the first direction, it will pass through the first heating element 200 and the second heating element 300 in sequence, and then be discharged from the notch of the groove 130.
[0053] At this time, when the first heating body 200 and the second heating body 300 are connected to an external power supply through the first wire 400 and the second wire 500, the first heating body 200 generates heat under the action of the electric current, and when the airflow flowing through the airflow channel 140 hits the first heating body 200, the airflow is heated by the first heating body 200.
[0054] Since the gas passing through the airflow channel 140 is cold air, the cold air enters the groove 130 through the airflow channel 140 and is heated by the first heating element 200 when passing through the first heating element 200. At the same time, the gas heated by the first heating element 200 can be combined with the heat released by the first heating element 200, and then the combined warm hot air flows in the direction of the second heating element 300, and after being heated by the second heating element 300, the temperature of the airflow passing through the second heating element 300 increases, and the heated gas is discharged from the notch of the groove 130.
[0055] It can be understood that the gas heated by the first heating element 200 and the second heating element 300 not only has a stable temperature, but also has a uniform and stable temperature without high and low temperature fluctuations. This not only improves the heating efficiency of the gas, but also ensures the uniformity and stability of the gas heating.
[0056] It should be noted that the shape of the first heating element 200 is the same as the shape of the second heating element 300, which can be any one of a curve, a broken line, a straight line, a mesh, or a combination of two or more, and can be specifically set according to actual conditions.
[0057] like Figure 1 and Figure 2 As shown, in this embodiment, the first heating element 200 and the second heating element 300 are both curved.
[0058] Furthermore, the material of the first heating element 200 and the second heating element 300 includes at least one of metal, ceramic, and glass.
[0059] In addition, in some embodiments, both the first heating element 200 and the second heating element 300 may be PTCs (Positive Temperature Coefficient, thermistors) to improve the heating efficiency of the air.
[0060] It is worth noting that the PTC thermistor is a typical temperature-sensitive semiconductor resistor. When the temperature exceeds a certain value (Curie temperature), its resistance value increases stepwise as the temperature rises.
[0061] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, along the projection of the first direction, the first heating element 200, the second heating element 300 and the air flow channel 140 overlap.
[0062] It can be understood that the shape of the air flow channel 140 is the same as the shape of the first heating element 200 .
[0063] It should be noted that by overlapping the projections of the first heating element 200 and the second heating element 300 along the first direction, the paths of the gas flowing through the first heating element 200 and the gas flowing through the second heating element 300 are made the same, thereby avoiding local uneven heating, thereby ensuring the consistency and uniformity of the gas heating by the first heating element 200 and the second heating element 300.
[0064] In addition, by overlapping the first heating body 200 and the airflow channel 140 along the first direction, the gas passing through the airflow channel 140 can be directly directed toward the first heating body 200, so as to avoid the gas flowing through the airflow channel 140 flowing away from the gap in the first heating body 200, so that the gas entering the groove 130 through the airflow channel 140 can be heated by the first heating body 200.
[0065] Furthermore, the gas flowing through the first heating element 200 integrates the heat released by the first heating element 200 and flows toward the second heating element 300 , and is discharged from the notch of the groove 130 after being heated by the second heating element 300 .
[0066] It should be noted that, since the second heating element 300 overlaps with the first heating element 200 , the heating capacity of the second heating element 300 for gas is the same as that of the first heating element 200 , and the uniformity of the heating of the gas by the second heating element 300 can be further improved.
[0067] like Figure 1 and Figure 4 As shown, in some embodiments of the present invention, a support platform 600 is provided at the bottom of the groove 130 , and the support platform 600 abuts against the first heating element 200 on one side facing the first heating element 200 , so as to provide support to the first heating element 200 through the support platform 600 .
[0068] In some other embodiments of the present invention, there are multiple second heating elements 300 , and the multiple second heating elements 300 are arranged at intervals along the first direction.
[0069] It should be noted that the plurality of second heating elements 300 are arranged at equal intervals along the first direction to avoid heating differences of the gas by different second heating elements 300, so as to ensure uniformity and stability of heating of the gas by two adjacent second heating elements 300.
[0070] Specifically, the distance between the first heating element 200 and the second heating element 300 is S1, and the distance between two adjacent second heating elements 300 is S2, wherein S1=S2, to ensure the heating quality and uniformity of the gas by each second heating element 300, so as to ensure that the gas temperature can be uniformly increased.
[0071] In this embodiment, the base 100 is a ceramic base 100, wherein ceramic has the advantages of excellent insulation, corrosion resistance, high temperature resistance, high hardness, low density, radiation resistance and the like.
[0072] Some embodiments of the present utility model provide an aerosol generating device, comprising the heating structure described in any one of the above embodiments.
[0073] Among them, the aerosol generating device has the structure and beneficial effects of the heating structure described in any of the above embodiments, which will not be described one by one here.
[0074] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.
[0075] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0076] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
