Description

Technical Field

[0001] This utility model belongs to the field of heating elements, and particularly relates to a pin structure of a heating module. Background Technology

[0002] In some hot air applications, heat is generated by energizing heating elements. Air blown over these elements carries away the heat, resulting in hot air being expelled. This is particularly useful in devices requiring a continuous supply of high-temperature air. Several heating elements are placed on a ring-shaped socket with openings. The elements are heated by electricity, and air is blown out through the openings. The air absorbs heat from the heating elements, rapidly increasing its temperature and maintaining it at a high level. To maximize heat conversion efficiency, the socket portion of the ring needs to be narrow, resulting in a larger opening. The heating elements extend into the opening, allowing air to flow over their surface. However, existing heating elements have leads at both ends, requiring a wider socket that is unsuitable for the aforementioned ring-shaped socket. Therefore, a heating element adapted for narrow-sided ring-shaped sockets is needed. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned problems by providing a pin structure for a heating module.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A pin structure for a heating module includes a heating element, a heating wire inside the heating element, two pins at the end of the heating element, at least one pin not located at the end of the heating element, and the two ends of the heating wire extending into the two pins respectively.

[0006] In the pin structure of the heating module described above, the portion of the heating wire extending into the pin is located on one side of the pin, and a portion of the heating wire is located on the outside of the pin.

[0007] In the pin structure of the heating module described above, the heating wire inside the pin is flush with one side of the pin.

[0008] In the pin structure of the heating module described above, the pins are fitted with sockets, and the sockets contain electrical plates or wires that are connected to the heating wires.

[0009] In the pin structure of the heating module described above, the heating wire coils several times inside the heating element, and a turning section is provided between the heating wire and the pin not located at the end of the heating element.

[0010] In the pin structure of the heating module described above, one pin is located at the end of the heating element, and the other pin is slidably located at the end of the heating element through an I-shaped groove. The pin slidably connected to the heating element is provided with a wire lead, which is always connected to one end of the heating wire.

[0011] In the pin structure of the heating module described above, the heating element is made of ceramic.

[0012] In the pin structure of the heating module described above, the pins are made of insulating material.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] 1. Only one of the two pins is at the end of the heating element, and the other is located in the middle of the end of the heating element. This greatly reduces the distance between the two pins, making it suitable for ring sockets with narrow edge pitch. Furthermore, the fact that one of the pins is located at the end of the heating element allows more of the heating element to extend into the hole of the ring socket, which greatly improves the heat exchange efficiency when the wind blows.

[0015] 2. The portion of the heating wire located at the pin is exposed outside the pin, allowing it to be directly inserted into the ring socket or inserted into the ring socket through the socket. The exposed heating wire can be directly connected to the lead wire in the socket without the need for additional connecting wires.

[0016] 3. By sliding one of the pins, the spacing between the two pins can be changed, improving adaptability and enabling it to accommodate ring sockets of different widths. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] This embodiment provides a pin structure for a heating module, combined with... Figure 1-3As shown, it includes a heating element 10, a heating wire 11 is provided inside the heating element 10, and two pins 12 are provided at the end of the heating element 10. At least one pin 12 is not provided at the end of the heating element 10, and the two ends of the heating wire 11 extend into the two pins 12 respectively.

[0023] In this embodiment, only one of the two pins 12 is at the end of the heating element 10, and the other is located in the middle of the end of the heating element 10. This greatly reduces the distance between the two pins 12, making it suitable for ring sockets with narrow side pitch. Furthermore, the fact that one of the pins 12 is located at the end of the heating element 10 allows more of the heating element 10 to extend into the hole of the ring socket, which greatly improves the heat exchange efficiency when the wind blows.

[0024] The portion of the heating wire 11 extending into the pin 12 is disposed on one side of the pin 12, and a portion of the heating wire 11 is disposed on the outside of the pin 12.

The exposed heating wire 11 can be directly connected to the lead wire in the socket 13 without the need for additional connecting wires.

[0026] The heating wire 11 inside the pin 12 is flush with one side of the pin 12.

[0027] In this embodiment, the heating wire 11 is not protruding from the pin 12, which facilitates direct insertion into the ring socket and connection via the socket 13.

[0028] The pin 12 is fitted with a socket 13, and the socket 13 contains an electric sheet or electric wire that is connected to the heating wire 11.

[0029] The heating wire 11 is coiled several times inside the heating element 10, and a turning section 14 is provided between the heating wire 11 and the pin 12 that is not located at the end of the heating element 10.

[0030] One pin 12 is located at the end of the heating element 10, and the other pin 12 is slidably located at the end of the heating element 10 through the I-shaped groove 16. The pin 12 slidably connected to the heating element 10 is provided with a wire lead 15, which is always connected to one end of the heating wire 11.

[0031] In this embodiment, by sliding one of the pins 12, the spacing between the two pins 12 can be changed, improving adaptability and enabling it to adapt to ring sockets of different widths.

[0032] The heating element 10 is made of ceramic.

[0033] The pin 12 is made of insulating material.
