The mainstream electric oil-filled heaters on the market are basically welded by sheet metal heater pieces, and the oil circuit is formed between the heater pieces by the ribs of the heater pieces themselves, and then the heat is transferred by flushing the oil through the oil circuit; this type of heater body wastes a lot of space due to the oil circuit restriction, the heat dissipation and heat transfer of the oil-filled heater are greatly restricted, and the manufacturing process is cumbersome and involves many welding steps; in response to this phenomenon, this design proposes an oil-filled heater structure with a separate oil circuit from the outer cover of the heater body. Summary of the invention

[0022] In order to better understand the purpose, structure and function of the present invention, the following Figure 1-4 , understanding of the present invention.

[0023] like Figure 1As shown, a separate oil circuit oil heater assembly is designed, including a housing, an oil storage assembly 5 arranged in the inner cavity of the housing, and a heating assembly 3 arranged in the oil storage assembly 5; wherein the housing includes an upper cover 1, a bottom cover 2, and a fastener, and the fastener can be a screw 4, such as Figure 3 As shown, when the upper cover 1 and the bottom cover 2 are buckled together, the heating component 3 is stuck between the ends of the upper cover 1 and the bottom cover 2, so that the oil storage component 5 is buckled in the inner cavity between the upper cover 1 and the bottom cover 2, and the screws 4 lock the upper cover 1 and the bottom cover 2 together.

[0024] The innovation of this design mainly lies in: Figure 2 and Figure 4 The designed oil storage assembly 5 is composed of an oil cylinder 51, a first oil storage pipe 52, and a second oil storage pipe 53. The first oil storage pipe 52 and the second oil storage pipe 53 are bent and fixed to the oil cylinder 51 by welding to form an oil storage part. At the same time, the oil pipe has the function of distributing the oil volume, thereby achieving the purpose of heat distribution. Among them, a heating assembly 3 is installed in the oil cylinder 51, and a plurality of oil storage pipes are connected through the outer wall of the oil cylinder 51, thereby separating the oil storage pipe from the inside of the oil cylinder 51. By separating the oil storage pipe in the oil storage assembly, the inside of the oil storage pipe is filled with a heat medium, such as oil, and the heat dissipation and heat transfer are performed through the layout path of the oil storage pipe, thereby saving the volume space of the oil heater. At the same time, the oil path structure direction can be arranged more arbitrarily, thereby achieving the purpose of arranging the heat distribution inside the heater body.

[0025] The oil cylinder 51 is a cylindrical structure, and the heating component 3 is installed in the hole of the cylindrical structure; and a hollow interlayer is provided inside the cylinder wall, so as to form a hollow structure for storing heat medium, and the hollow structure of the heat medium stores oil, and then the oil inside can transfer heat back and forth with the oil inside the oil storage. Among them, the oil storage pipe includes a plurality of first oil storage pipes 52 and second oil storage pipes 53, and the first oil storage pipe 52 is set as an arch structure, and both ends of the first oil storage pipe 52 are connected with the heat medium in the oil cylinder 51. And the first oil storage pipes 52 are linearly arranged in the axial direction of the oil cylinder 51, and each first oil storage pipe 52 can store oil, and heat transfer occurs with the hot oil in the oil cylinder 51 to achieve a heating effect. Further, both ends of the second oil storage pipe 53 are connected with the heat medium in the oil cylinder 51, and the second oil storage pipe 53 passes through the arch ring of the first oil storage pipe 52 in sequence, which can increase the oil storage capacity. At the same time, due to the penetration inside the arch ring, the heat control is better. The second oil storage pipe 53 is a bent pipe, which is also an oil pipe and is welded to the oil cylinder 51. The bending has two purposes: one is to adjust the oil circuit layout through bending, and the other is to adjust the overall oil filling amount.

[0026] The design is further optimized, and the sizes of the multiple first oil storage tubes 52 are set from low to high, arranged in sequence along the axial direction of the oil cylinder 51, and the first oil storage tube 52 with the lowest size is set at one end close to the heating component 3. The layout of the oil storage tubes of this design is arranged from low to high from the position close to the heating pipe mouth, so that the overall heating of the heater body is more balanced; the upper and lower shells are used to wrap the oil circuit and the heating component on the outside of the heater body to form an oil heater assembly. The highest first oil storage tube 52 has a high oil circuit farthest from the end of the electric heating element 31, and the oil storage capacity is also the largest, and the lowest first oil storage tube 52 has a low oil circuit closest to the end of the electric heating element 31, and the oil storage capacity is also the least. Therefore, the oil circuit layout can achieve balanced thermal energy, and its principle is: 1. The less oil storage capacity, the less thermal energy is stored in the end; the more oil storage capacity, the more thermal energy is stored in the end; 2. The heat is fast and the heat energy is high near the heating element end; the heat is slow and the heat energy is low far away from the heating element end.

[0027] like Figure 1 The heating assembly 3 includes an electric heating element 31 installed in the hole of the oil cylinder 51, and a heat-conducting rod connected to the electric heating element 31. The heat-conducting rod is detachably inserted into the hole of the oil cylinder 51. A sealing ring 32 and an inner thread 33 are sleeved in the heat-conducting rod. The inner thread 33 locks the electric heating element 31 and the hole end of the oil cylinder 51 together. The inner thread 33 is welded to the oil storage element.

[0028] The oil heater assembly of the separated oil circuit designed by the present invention is used in an electric heater. The designed electric heater greatly saves the volume space of the oil heater. At the same time, the oil circuit structure direction can be arranged more arbitrarily, so as to achieve the purpose of arranging the heat distribution inside the heater body, and more accurately control the heat dissipation and heat transfer capabilities of the oil heater, fundamentally change the heat transfer and heat dissipation capabilities of the oil heater, and bring users a better experience effect.

[0029] In assembling the oil heater components, such as Figure 4 The overall structure is as follows: weld the inner thread 33 to the open end of the oil storage component 5, load the heat transfer oil into the oil storage component 5, tighten the sealing ring 32 of the heating component 3 and the oil storage component 5 through the screw thread to form a sealed cavity, and finally, connect the upper cover 1 and the bottom cover 2 together through the screws 4; after the power is turned on, the oil heater as a whole heats up.
