Description

Technical Field

[0001] This utility model relates to the field of ceramic heating element technology, and in particular to a rapid heating ceramic heating element. Background Technology

[0002] Ceramic heating elements are a type of high-efficiency heating element that is widely used in various applications requiring precise temperature control, such as medical equipment, laboratory instruments, and household appliances.

[0003] Ceramic heating elements are widely used in various applications requiring precise temperature control, such as medical equipment, laboratory instruments, and household appliances. For example, in medical equipment, ceramic heating elements can be used to heat blood and medicines. According to the authorized publication number "CN201673368U", a ceramic heating element is disclosed, comprising a substrate, a heating element, and a glass layer. The heating element is laid on the surface of the substrate, and the glass layer covers the entire heating element. The heating element is shaped into a wave pattern. The substrate is an alumina plate. The thickness of the glass layer is 1 mm or more. With the above-mentioned technical improvement, by changing the traditional linear heating element to a curved wave-shaped heating element, the length of the heating element on the substrate is increased. Compared with traditional ceramic heating elements of the same type, it heats up faster and generates more heat per unit time, thereby improving the quality and efficiency of fixing.

[0004] Currently, when using ceramic heating elements, it is necessary to ensure that they have sufficient strength to avoid damage to the ceramic material during accidental collisions. At the same time, when installing them with equipment, most ceramic heating elements are connected to the equipment housing by screws running through the entire assembly. This not only damages the ceramic heating element itself, but also makes it inconvenient to operate with tools when the internal space of the housing is narrow during disassembly and maintenance.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Reference Figures 1-5 A rapid heating ceramic heating element includes a heating element body 1. Connecting seats 11 are provided on both sides of the heating element body 1. The lower end of the connecting seat 11 is fixedly installed to the heating element body 1 by fastening bolts 12. The fastening bolts 12 can stably fix the connecting seat 11 to the heating element body 1, so that the positioning seat 17 can be installed.

[0026] A mounting base 13 is also closely attached to one side of the heating element body 1. The mounting base 13 is made of high-strength plastic material. Positioning sleeves 14 are fixed through both sides of the mounting base 13. Positioning pins 15 are slidably inserted into the inside of the positioning sleeves 14. Springs 16 are wound around the surface of the positioning pins 15. The two ends of the springs 16 are fixedly installed to the end faces of the positioning sleeves 14 and the end faces of the positioning pins 15, respectively. A positioning seat 17 is provided on the side of the connecting seat 11 away from the heating element body 1. The end of the positioning pin 15 away from the spring 16 is inserted and connected to the inside of the positioning seat 17. When it is necessary to disassemble and repair the heating element body 1, it is only necessary to pull the positioning pins 15 distributed on both sides to stretch the springs 16, thereby allowing the positioning pins 15 to separate from the positioning seat 17, thus realizing the disassembly operation of the heating element body 1 and the mounting base 13.

[0027] The mounting base 13 is provided with mounting plates 2 at both ends. The mounting plates 2 and the mounting base 13 are integral structures. One side of the mounting plate 2 is flush with the surface of the mounting base 13, which ensures the stable positioning of the mounting base 13 when it is installed with the housing.

[0028] The mounting plate 2 has a mounting hole 21 that extends through it. The inner wall of the mounting hole 21 is a smooth surface with threaded edges. The mounting hole 21 can be fixed to the housing of the equipment with screws or bolts, so that the mounting base 13 does not need to be disassembled when the heating element body 1 is being repaired.

[0029] The heating element body 1 comprises, in sequence, an insulating layer 101, an insulating layer 102, a base layer 103, a base layer 104, a protective layer 105, and a protective layer 106. The insulating layer 101 and the insulating layer 102 are fixed together by screws. The base layer 103 is fixedly covered on the other side of the insulating layer 101, and the protective layer 105 is fixedly covered on the other side of the base layer 103. The base layer 104 is fixedly covered on the other side of the insulating layer 102, and the protective layer 106 is fixedly covered on the other side of the base layer 104. Through the combination of the multi-layer structure, the heating process of the entire heating element body 1 is more stable and safe.

[0030] Among them, an electric heating wire 10101 is fixedly installed between the first insulation layer 101 and the second insulation layer 102. The two ends of the electric heating wire 10101 are respectively provided with power-on interfaces 10102. The power-on interfaces 10102 are connected to an external temperature control switch through wires. By turning on the power, the electric heating wire 10101 can be heated and generate heat.

[0031] Among them, insulating layer 101, insulating layer 102, base layer 103, and base layer 104 are all made of ceramic material. The base layer structure has good thermal conductivity and high temperature resistance. The insulating layer structure is used to prevent short circuit between the heating element and the ceramic substrate. Insulating layer 101 is located between the heating element and base layer 103, and insulating layer 102 is located between the heating element and base layer 104. Their main function is to prevent short circuit between the heating element and the ceramic substrate and ensure the safe operation of the heating element. At the same time, the insulating layer can also reduce the transfer of heat to the ceramic substrate and improve the heating efficiency.

[0032] Both protective layer 105 and protective layer 106 are made of stainless steel and are used to protect the heating element and insulation layer from the influence of the external environment. Protective layer 105 is located outside insulation layer 101, and protective layer 106 is located outside insulation layer 102. Their main function is to protect the heating element and insulation layer from the influence of the external environment, such as dust, moisture, and chemical corrosion. At the same time, the protective layers can also improve the mechanical strength of the heating element and extend its service life.

[0033] In practice

[0034] In this design, the heating element body 1 is quickly installed and disassembled via connecting seats 11 and positioning seats 17 on both sides. The connecting seats 11 are fixed to the heating element body 1 by fastening bolts 12 to ensure the stability of the positioning seats 17. Positioning pins 15 are slidably inserted into the positioning sleeves 14 on both sides of the mounting seat 13. The springs 16 wound on the surface of the positioning pins 15 are fixed at both ends to the end faces of the positioning sleeves 14 and the positioning pins 15, respectively, forming an elastic reset structure. When the heating element body 1 needs to be disassembled, the positioning pins 15 on both sides are pulled outward, the springs 16 are stretched, the positioning pins 15 are disengaged from the positioning seats 17, and the heating element body 1 can be separated from the mounting seat 13. During installation, the positioning pins 15 only need to be aligned with the positioning seats 17, the springs 16 rebound and push the positioning pins 15 into the positioning seats 17 to complete the automatic locking. The mounting plates 2 at both ends of the mounting seat 13 are fixed to the equipment housing through mounting holes 21. During maintenance, only the heating element body 1 needs to be disassembled, and the mounting seat 13 does not need to be changed, which greatly improves maintenance efficiency.

[0035] The heating element body 1 is composed of an insulation layer 101, an insulation layer 2 102, a base layer 103, a base layer 2 104, a protective layer 105, and a protective layer 2 106. An electric heating wire 10101 is fixed between the insulation layer 101 and the insulation layer 2 102. The two ends of the wire 10101 are connected to an external temperature control switch via energized interfaces 10102. When energized, the electric heating wire 10101 heats up, and the heat is conducted to both sides through the insulation layer 101 and the insulation layer 2 102. The insulation layer 101 and the base layer 103, as well as the insulation layer 2 102 and the base layer 2 104, are all made of ceramic material, which has both high thermal conductivity and electrical insulation properties. This allows for rapid heat transfer while preventing short circuits between the electric heating wire 10101 and the base layer. The base layer 103 and the base layer 2 104 further distribute the heat evenly. The protective layers 105 and 2 106 are made of stainless steel, which isolates external dust and moisture while enhancing mechanical strength. The multi-layer structure works together to achieve efficient heating, safe insulation, and durable protection.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
