[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0023] Depend on Figure 1 and Figure 2 As shown, it is a structural schematic diagram of the combined PTC heater in this embodiment. The heater includes a heater body 1, side guard plates 2 and connecting blocks 3. Side guard plates 2 are provided on both sides of the heater body 1. There are two sets of side guard plates 2. Connecting blocks 3 are installed on the side of the heater body 1. The heater body 1 is composed of multiple sets of heating elements. An insertion mechanism 4 for assisting the heater body 1 to dock is installed on the heater body 1.

[0024] Depending on the installation location and usage scenario, multiple heating elements are connected and combined to form the heater body 1. The heater body 1 is then placed between the side guard plates 2. The side guard plates 2 reinforce and lock the heater body 1, thus strengthening the overall heater components. After that, the connecting lines are connected to the connecting block 3 to provide power for the operation of the heater body 1 and assist the overall operation of the heater.

[0025] From the appendix Figure 2 and Figure 3 As shown, the insertion mechanism 4 includes an insertion ceramic plate 41, an anti-sliding block 42, a docking groove 43, and a mating block 44. A docking groove 43 is provided on the side wall of multiple heating elements. The insertion ceramic plate 41 is slidably installed in the docking groove 43. Anti-sliding blocks 42 are symmetrically fixed on both sides of the insertion ceramic plate 41. The docking grooves 43 are slidably connected to each other. Multiple mating blocks 44 are equidistantly installed on the side wall of the side guard plate 2. The mating blocks 44 are slidably inserted into the docking grooves 43 on the heating elements.

[0026] In use, multiple heating elements are arranged flat, ensuring that the mating grooves 43 in each heating element are aligned. Then, the insert ceramic plate 41 is pressed into the mating groove 43, so that the anti-sliding block 42 enters the heating elements on both sides at the same time, reinforcing and locking the positions of the two sets of heating elements that are in contact, completing the overall docking and assembly of the heater body 1. The installation of the mating block 44 allows the heater body 1 to be stably installed between the side guard plates 2, quickly completing the installation and assembly of the components.

[0027] From the appendix Figure 4 As shown, this is a structural schematic diagram of the support mechanism 5 in this embodiment. The PTC heater also includes the support mechanism 5, which includes a concave frame 51, a connecting piece 52, and a positioning rod 53. The heater body 1 has multiple sets of concave frames 51 on its side. The concave frame 51 has a positioning groove for positioning with the connecting block 3. The connecting piece 52 is installed on one side of the surface of the concave frame 51, and the positioning rod 53 is installed on the side of the connecting piece 52. The other side of the surface of the concave frame 51 has a slot, which is slidably inserted into the positioning rod 53. The side guard plate 2 has two sets, and the upper surface of the side guard plate 2 has an insertion groove for insertion with the positioning rod 53.

[0028] During use, after the heater body 1 is assembled and spliced, the corresponding concave frame 51 is selected according to the number of connecting blocks 3. The positioning groove on the concave frame 51 is used to make the concave frame 51 fit against the bottom of the connecting block 3. Then, through the cooperation of the connecting piece 52 and the positioning rod 53, the concave frames 51 are assisted to dock and lock the overall position of the concave frame 51, providing calibration and support for the connecting block 3. The edge of the concave frame 51 is connected to one of the side guard plates 2 to prevent the overall position of the assembled concave frame 51 from shifting.

[0029] From the appendix Figure 5 As shown, this is a structural schematic diagram of the splicing mechanism 6 in this embodiment. The PTC heater also includes the splicing mechanism 6, which includes a barrier plate 61, an extension arm 62, a partition plate 63, and a positioning plate 64. The positioning plate 64 is fixedly installed at the end of the side guard plate 2. The barrier plate 61 is arranged between the positioning plates 64. The extension arm 62 is symmetrically installed at both ends of the barrier plate 61. Multiple sets of partition plates 63 are equidistantly installed on the lower surface of the extension arm 62. A gap is formed between the partition plates 63, and the gap is slidably connected to the positioning plate 64. A protruding plate is installed at the end of the positioning plate 64.

[0030] In use, the assembled heater body 1 is installed between the side guard plates 2 to determine the spacing between the side guard plates 2. Then, the baffle plate 61 is inserted between the side guard plates 2 so that the baffle plate 63 and the positioning plate 64 are aligned to lock the spacing at the bottom of the side guard plates 2, thereby achieving the initial positioning of the side guard plates 2 and providing shielding and protection for the overall operation of the heater body 1.

[0031] From the appendix Figure 5 As shown, the splicing mechanism 6 also includes a support plate 65, a snap-fit ​​block 66, and a support frame 67. A snap-fit ​​block 66 is installed at the end of the side guard plate 2 and at the end away from the positioning plate 64. A support plate 65 is provided on the side of the side guard plate 2. Multiple sets of slots for inserting into the snap-fit ​​block 66 are equally spaced on the support plate 65. A support frame 67 for calibrating and limiting the connection block 3 is installed on the upper surface of the support plate 65.

[0032] When one end of the side guard plate 2 is positioned, the support plate 65 is inserted into the other end of the side guard plate 2. The Shudie snap-fit ​​block 66 enters the slot in the support plate 65. During the insertion process, the support frame 67 can provide support for the middle part of the connecting block 3, making the overall practical effect of the equipment more efficient.

[0033] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
