[0040] The specific embodiments of the application will be described in detail below with reference to the accompanying drawings. The heating assembly can be used in various electric heating applications, such as household appliances, for example, water dispensers. The size of the heating assembly can be very small, and it can be applied to personal care products, such as aerosol generating devices, specifically, essential oils, medicaments, tobacco, etc.

[0041] Reference Figure 1 , Figure 2A heating assembly includes a substrate 1, which is a tubular structure. The heating assembly has a heating region 2 and an electrode region 3. The electrode region 3 has a first electrode 31 and a second electrode 32 facing each other. The first electrode 31 and the second electrode 32 are arranged circumferentially along the tubular substrate 1. The heating region 2 has two or more film regions 4. Each film region 4 has a first connecting portion 41 and a second connecting portion 42. The first connecting portion 41 and the second connecting portion 42 are located at two ends of the film region 4 along the length direction of the tubular substrate 1. The first connecting portion 41 is electrically connected to the first electrode 31, and the second connecting portion 42 is electrically connected to the second electrode 32. The heating assembly has at least one insulating region 6, which is located between the first electrode 31 and the second electrode 32 and between adjacent film regions 4.

[0042] The film region 4 has a heating resistor 5 disposed on the surface of the tubular substrate 1. The heating resistor 5 can be various electrothermal films or printed circuits, such as heating films with a film thickness within 50 micrometers, such as 5 micrometers, 4 micrometers, 3 micrometers, 2 micrometers, 1 micrometer, 5 nanometers, 4 nanometers, 3 nanometers, 2 nanometers, 1 nanometer, etc.

[0043] Because the heating zone 2 has two or more film zones 4, which are spaced apart and each film zone 4 is electrically connected to the electrode zone 3, each film zone 4 is an individual heating resistor that can work in parallel and independently. If one film zone 4 is damaged due to an accident, the other film zones 4 can still function normally, thus maintaining the heating function of the heating component and improving its durability. Especially in cases of dry burning, the heating component's resistance to dry burning is also improved.

[0044] In addition, when the heating resistor is an electrothermal film, due to the process limitations of setting the electrothermal film on the substrate surface, the electrothermal film is set on the substrate surface by coating, spraying, or plasma sputtering. When the entire substrate surface is covered with electrothermal film, the uniformity of the electrothermal film may be insufficient due to the large area of ​​the electrothermal film. However, by separating the film areas 4, the area of ​​the electrothermal film in each film area 4 is reduced, which is beneficial to the uniformity of each film area 4. In one case, at least two adjacent film areas 4 have the same resistance, so that different film areas 4 are set separately, which improves the uniformity of the film areas 4 and also improves the durability of the heating component.

[0045] In one case, at least two adjacent membrane regions 4 have different resistance values, and these different membrane regions 4 can also be controlled to have different heat generation.

[0046] In one case, at least two adjacent membrane regions 4 have the same area, which improves the uniformity of membrane regions 4 and enhances the durability of the heating component.

[0047] In one case, the area of at least two adjacent film regions 4 is different, and the film regions 4 can also be controlled to have different heat generation amounts.

[0048] Since the heating zone has two or more film regions 4 arranged at intervals, the composition of the electrothermal film of the film regions 4 can be different, so that the resistance value of each film region 4 is designed to be different as needed, and the application is wider than that of a single film.

In this way, the current is input from the first electrode 31 at one end of the substrate 1 to each film region 4 and output through the second electrode 32 at the other end of the substrate 1, so that each film region 4 is connected in parallel and the circuits between them are not affected.

[0051] Of course, as another embodiment, the film regions 4 can also extend around the circumferential side of the substrate.

[0052] The length direction of the substrate 1 is the direction in which the first and second electrodes 31 and 32 extend to connect the film regions 4, the width of the first and second connecting portions 41 and 42 is not less than 2 mm, the distance between at least two adjacent film regions 4 is not greater than the width of the first and second connecting portions 41 and 42, and the width of the first and second electrodes 31 and 32 is greater than the width of the first and second connecting portions 41 and 42.
