[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] As Figures 1-5 shown, a cluster-type heater assembly includes a fixed frame 1, a heating tube 5 and a mounting part 4: The bottom of the fixed frame 1 has a plurality of connecting sleeves 3, where the connecting sleeve 3 and the fixed frame 1 are in a welded relationship, and the fixed frame 1 is used for carrying the installation of parts; The heating tube 5 is arranged below the fixed frame 1. After the heating tube 5 is powered on, it will be heated. The top ends of the heating tubes 5 all have convex plates 51, and the convex plates 51 and the heating tubes 5 are in a welded relationship; The cross-sections of the heating tube 5 and the convex plate 51 are both circular, which are used to cooperate with the mounting part 4 for plugging and rotating, and the diameter of the convex plate 51 is greater than the diameter of the heating tube 5, which can limit the convex plate 51 inside the mounting part 4 and prevent the heating tube 5 from falling off the mounting part 4; A part of the mounting part 4 is inserted into the connecting sleeve 3, and the mounting part 4 is used for disassembling and installing the heating tube 5. The bottom of the mounting part 4 is inserted with a part of the heating tube 5. The mounting part 4 can make the top of the heating tube 5 rotate locally, which is convenient for the disassembly and assembly of the heating tube 5.

[0026] The mounting part 4 includes a rotating plate 42 sleeved on the top of the heating tube 5. The rotating plate 42 is designed as a cylinder, which will wrap the convex plate 51 and the top of the heating tube 5. The mounting threaded post 41 fixed on the top of the rotating plate 42 has threads engraved on the surface. The connecting sleeves 3 are arranged in a rectangular array at the bottom of the fixed frame 1, which is convenient for installing multiple heating tubes 5. Thread grooves are opened inside the connecting sleeves 3, and the thread grooves are threadedly connected with the mounting threaded posts 41, which can install the heating tubes 5. The mounting threaded posts 41 are inserted into the connecting sleeves 3, which is convenient for the disassembly and assembly of the heating tubes 5 and subsequent maintenance. A notch is opened at the bottom of the rotating plate 42. The notch and the rotating plate 42 are integrally formed, and the internal dimension of the notch is larger than the opening dimension of the notch. The diameter of the convex plate 51 is smaller than the internal dimension of the notch and larger than the opening dimension of the notch. The rotating plate 42 rotates around its own axis. The inside of the notch will be inserted into the convex plate 51, and the opening of the notch will be inserted into the heating tube 5. When in use, the rotating plate 42 can rotate along its own axis on the surfaces of the heating tube 5 and the convex plate 51 to help disassemble and replace the heating tube 5.

[0027] The effect achieved by the entire first embodiment is as follows. Specifically, when in use, first insert the installation threaded post 41 at the top of the heating tube 5 into the connecting sleeve 3. At this time, rotate the convex plate 51 and the rotating plate 42 at the top of the heating tube 5. When the rotating plate 42 rotates, it will drive the installation threaded post 41 to rotate synchronously. At this time, the threads on the surface of the installation threaded post 41 will cooperate with the threads inside the connecting sleeve 3 for plugging to fix the heating tube 5. Since the installation part 4 can rotate independently, when the installation threaded post 41 rotates, the heating tube 5 will not rotate accordingly, which is convenient for the maintenance and replacement of the heating tube 5.

[0028] Second Embodiment

[0029] As Figures 1-5 shown, a cluster-type heater assembly, the installation part 4 further includes a rubber pad 43 fixed to the inner top of the rotating plate 42. The rubber pad 43 is made of rubber material, and the bottom of the rubber pad 43 abuts against the circumferential side of the top of the convex plate 51. When in use, the rubber pad 43 will separate the top of the convex plate 51 from the inner top of the rotating plate 42, reducing the wear of the contact part between the top of the convex plate 51 and the inside of the rotating plate 42.

[0030] The installation part 4 further includes a first electrical connection point 44 arranged between the rubber pads 43. The first electrical connection point 44 is also fixed at the center position of the inner top of the rotating plate 42. The heating tube 5 also has a second electrical connection point 52 fixed to the top end of the convex plate 51. The top of the second electrical connection point 52 abuts against the bottom of the first electrical connection point 44. When in use, when the second electrical connection point 52 abuts against the first electrical connection point 44 and the installation threaded post 41 and the connecting sleeve 3 are fixed, when the fixed frame 1 is powered on, the heating tube 5 will perform a heating operation.

[0031] A plurality of plugging slots 2 are fixed on the outer side wall of the fixed frame 1, and the plugging slots 2 are equally spaced along the horizontal extension line of the fixed frame 1.

[0032] The effect achieved by the entire second embodiment is that when the second electrical connection point 52 abuts against the first electrical connection point 44 and the installation threaded post 41 and the connecting sleeve 3 are fixed, when the fixed frame 1 is powered on, the current generated by the resistance heats it to reach the required temperature, thereby realizing the heating effect. The heating wire inside the heating tube 5 is made of an alloy wire with a high resistivity. When powered on, the heating wire has energy loss and generates heat through the resistance to heat. The heating fiber bundle is formed by connecting multiple heating fibers in series to connect to the power supply.

[0033] Working principle: When using this cluster-type heater assembly, an external power supply is connected. First, the mounting threaded post 41 at the top of the heating tube 5 is inserted into the connecting sleeve 3. At this time, the convex plate 51 and the rotating plate 42 at the top of the heating tube 5 are rotated. When the rotating plate 42 rotates, it will drive the mounting threaded post 41 to rotate synchronously. At this time, the threads on the surface of the mounting threaded post 41 will cooperate with the threads inside the connecting sleeve 3 for plugging to fix the heating tube 5. Since the mounting part 4 can rotate independently, when the mounting threaded post 41 rotates, the heating tube 5 will not rotate along with it, which is convenient for the maintenance and replacement of the heating tube 5;

[0034] Secondly, when the second power connection point 52 abuts against the first power connection point 44, and after the mounting threaded post 41 and the connecting sleeve 3 are fixed, when the fixed frame 1 is powered on, due to the current generated by the resistance, it is heated to reach the required temperature, thus realizing the heating effect. The heating wire inside the heating tube 5 is made of alloy wire with high resistivity. When powered on, the heating wire has energy loss and is heated by the heat generated by the resistance. The heating fiber cluster is to connect multiple heating fibers to the power supply in series.

[0035] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.
