Description

Technical Field

[0001] The utility model relates to the field of heating components and electric irons, in particular to a heating component and an electric iron with the heating component. Background Art

[0002] An electric iron is one of the commonly used modern household appliances, mainly used for ironing clothes. According to different designs of the electric iron, there are many types. It can be divided into stainless steel bottom plates, Teflon non-stick bottom plates, coated bottom plates, gold-coated bottom plates, etc. according to different bottom plates, and can be divided into electronic temperature control and mechanical temperature control according to different temperature control methods, and can be divided into corded irons and cordless irons according to different carrying methods. Existing electric irons often use steam for heating, with poor heating effect and a lot of heat loss; at the same time, the ironing part of the electric iron often directly contacts the main body, which easily causes the temperature of the main body part to rise during operation, easily affects the service life of the internal control board of the main body, and seriously causes the housing to be deformed by heat, and also causes waste of some heat.

[0003] Chinese Patent Publication No. CN220413834U discloses an iron structure with a detachable bottom panel, which relates to the technical field of irons, including an iron main body, and a bottom panel device is arranged at the bottom of the iron main body. Upper and lower connecting devices are fixedly installed at the connection parts of the left and right ends of the iron main body and the bottom panel device. By installing the upper and lower connecting devices, the iron main body and the bottom panel device can be connected, and subsequent disassembly and installation are convenient. By pulling the pulling gear, the rotating rod rotates to separate the second clamping plate from the first clamping plate. When installing the bottom panel device, the water flowing in from the water outlet can be vaporized into water vapor in the steam cavity and discharged to the outside through the steam holes. At the same time, heat is conducted by the heating element to the bottom panel, and the two cooperate with each other to iron the clothes flat. The arranged positioning posts and positioning holes can be connected together to position the installation of the bottom panel and the upper part of the iron, and more conveniently enable the subsequent upper and lower connecting devices to be clamped together. This patent uses steam for heating, and only the heat of the part in contact with the ironing board is utilized, while the heat near the main body part is wasted and the thermal energy utilization is insufficient.

[0004] Chinese Patent Publication No. CN217839477U relates to the technical field of electric irons and discloses an electric iron. The handle assembly includes a face cover, which is connected to a mating cover through a rotating shaft mechanism. A second circuit board is arranged inside the mating cover, and a first circuit board is arranged inside the sleeve. The pressing plate, upper high-temperature yellow paper, heating film, lower high-temperature yellow paper, and heating plate are sequentially installed from top to bottom at the mating end of the base and the bottom shell. The utility model has flexible folding and storage performance. Through the rotation and swing of the rotating shaft mechanism inside the handle assembly, the handle of the electric iron can be folded and retracted, thereby reducing the occupied space of the electric iron and improving its portability. Moreover, during the ironing process, through the wrapping and protection of the heating plate by the bottom shell in the heating assembly and the wrapping of a breathable fabric on the heating plate, the user can be prevented from directly touching the heating plate. On the one hand, it can avoid scalding the hand, and on the other hand, it can avoid burning the clothes. Although this patent records that the heating film generates heat, it connects the heating film to the heating plate, and then the heating plate transfers the heat to the bottom plate for ironing. Multiple heat transfers will result in more heat loss. Summary of the Invention

The heating component is connected to the body through multiple heat insulation columns 151. After being heated by the heating component bracket, ironing operation is carried out, and the heat conduction effect is more direct. The heating component includes a heating component fixing plate 1522. The heat insulation columns 151 are arranged on the heating component fixing plate and connected to the main body, so that there is a gap between the main body and the ironing part. The lower end of the heating component fixing plate is provided with a heating component bottom plate 1524, and a heating film group 1523 is arranged between the heating component bottom plate and the heating component fixing plate. After the heating film group is heated, the heat is transferred to the heating component bottom plate 1524 for ironing. A connector 1520 is arranged on the heating component fixing plate. The connector is connected to the heating component fixing plate through a sealing ring 1521, and the connector is connected to the main body to supply power to the heating film group to make the heating film work. This method makes the heat generated by the heating film group directly act on the heating component bottom plate, the heat transfer is more direct, and the ironing effect is better.

[0043] Furthermore, for the heating film group, PI films are connected to both ends of the heating film, and a mica sheet is connected to the upper end of the PI film on the side facing the body for heat insulation, so that more heat of the heating film is transferred to the heating component bottom plate 1524 for ironing operation.
