The heating wire is fixed on a ceramic disc, and the head and tail ends of the heating wire are connected to a terminal. The terminal penetrates through the ceramic disc and a power cord fixing porcelain base and is electrically connected to the power cord. The outer ring of the ceramic disc is covered with a housing, and the housing is connected to the power cord fixing porcelain base. The power cord fixing porcelain base is arranged on a mounting bracket, and a through hole for accommodating the power cord is processed on the side of the mounting bracket."

A connection head is connected to the side of the heating element bottom plate facing the heating wire. The connection head is columnar. The head and tail ends of the heating wire are respectively provided with terminals. The terminals extend along the length direction of the connection head. The connection head is provided with a limiting groove corresponding to the terminal. The connection head and the terminal are connected and matched to form a plug-in structure that can be electrically connected to an external power source.

[0009] As a specific solution, the connection head is integrally processed from a high-temperature resistant insulating material.

[0010] As a specific solution, the connection head is provided with a screw hole, and a joint screw is connected to the screw hole. The joint screw is respectively connected and fixed to the screw hole and the heating element bottom plate.

[0011] As a specific solution, a limiting step is provided in the screw hole, and the screw cap of the connecting screw penetrates into the screw hole as a whole and abuts against the limiting step.

[0012] As a specific solution, the heating element bottom plate is connected with a housing, the outer side of the housing has a surrounding edge, and an installation cavity corresponding to the heating element bottom plate is formed between the surrounding edge and the housing.

[0013] As a specific solution, an installation bottom frame is connected to the side of the housing facing away from the heating element bottom plate, the installation bottom frame and the heating element bottom plate are connected and fixed by a screw device, the installation bottom frame has a connecting flange that can be installed and connected to an external device, and a plurality of screw holes are distributed on the connecting flange.

[0014] As a specific solution, a hollow cavity is formed inside the installation bottom frame.

[0015] The beneficial effects of the present utility model are as follows:

[0020] The present utility model will be further described below with reference to the drawings and embodiments.

[0021] Referring to Figures 1-3 , this new type of heater includes a heating element bottom plate 1, a heating wire 2 is provided on one side of the heating element bottom plate 1, a wiring head 3 is connected to the side of the heating element bottom plate 1 facing the heating wire 2, the wiring head 3 is columnar, wiring terminals 4 are respectively provided at the head and tail ends of the heating wire 2, the wiring terminals 4 extend along the length direction of the wiring head 3, and a limiting groove 31 corresponding to the wiring terminals 4 is provided on the wiring head 3. The limiting groove 31 can improve the connection stability between the wiring terminals 4 and the wiring head 3 and reduce the chance of the wiring terminals 4 shifting.

[0022] The terminal 3 is connected and cooperated with the terminal block 4 to form a plug-in structure capable of being electrically connected to an external power supply. By providing the terminal 3, the terminal block 4 can extend through the heating element base plate 1 toward the side facing away from the heating wire 2, and it is easier for the terminal block 4 to be energized and connected to the external power supply with a relatively short wire (the external power supply is usually arranged on the machine base), reducing the overall material cost of the product.

[0023] Furthermore, the terminal 3 is integrally formed by a high-temperature resistant insulating material to ensure the durability and safety of the terminal 3. For example, the terminal 3 can be formed by materials such as ceramic fiber or polytetrafluoroethylene.

[0024] Furthermore, a screw hole 32 is provided on the terminal 3, and a joint screw 5 is connected to the screw hole 32. The joint screw 5 is respectively connected and fixed to the screw hole 32 and the heating element base plate 1 to ensure the connection strength between the terminal 3 and the heating element base plate 1.

[0025] Furthermore, a limiting step 321 is provided in the screw hole 32, and the screw cap of the joint screw 5 integrally extends into the screw hole 32 and abuts against the limiting step 321, which can achieve the effect of hiding the joint screw 5 and making the product more beautiful.

The outer side of the housing 6 has a surrounding edge 61, and an installation cavity corresponding to the heating element base plate 1 is formed between the surrounding edge 61 and the housing 6. The housing 6 can protect the heating element base plate 1 and reduce the chance of damage to the heating element base plate 1.

[0027] Furthermore, an installation base frame 7 is connected to the side of the housing 6 facing away from the heating element base plate 1. The installation base frame 7 and the heating element base plate 1 are connected and fixed by a screw device. The installation base frame 7 has a connecting flange 71 capable of being installed and connected to an external device. A plurality of screw holes are distributed on the connecting flange 71. The installation base plate can make it easier for the product to be installed and connected to an external device (such as the protective cover of a heater).

[0028] Furthermore, a hollow cavity 72 is formed inside the installation base frame 7, making the overall material consumption of the installation base frame 7 less and the overall weight lighter. Moreover, the joint screw 5 can more easily pass through the installation base frame 7.
