Description

Technical Field

[0001] The utility model relates to the technical field of fog machines, in particular to an electromagnetic heating type fog machine heater. Background Art

[0002] A fog machine is a device that can generate vapor or smoke. Its working principle is as follows: Using special smoke oil (or water) as the raw material for generating smoke, the heater heats the raw material. When the liquid raw material is heated to an appropriate temperature, it volatilizes into a gas. After the volatilized gas is ejected and contacts a low-temperature environment (such as room-temperature air), it quickly condenses to form tiny droplets or particles, thus forming a smoky substance. The smoke is discharged through the exhaust device and diffuses into the indoor or outdoor environment.

[0003] The heaters of existing fog machines usually adopt cast aluminum heaters. The material of aluminum alloy makes the maximum operating temperature of the heater 300 °C, and it can only be used to heat water and some low-boiling-point smoke oils, so the application range is relatively narrow. In addition, due to its own volume and heat conduction principle, the cast aluminum heater needs to be preheated for 2 - 4 minutes or even longer when used for the first time, which has a large lag in the civil air defense and military fields. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an electromagnetic heating type fog machine heater to solve the problems of the existing cast aluminum heater of the fog machine having a low maximum operating temperature and requiring preheating when used for the first time.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: An electromagnetic heating type fog machine heater, comprising:

[0006] An oil pipe, one end of which is provided with an oil inlet joint, and the opposite end is provided with an outlet joint. The oil pipe between the oil inlet joint and the outlet joint is wound to form an annular heating pipe body part, and the oil pipe is a steel pipe;

[0007] A high-frequency current coil, which is wound outside the annular heating pipe body part.

[0008] As a further description of the above technical scheme:

[0009] The oil pipe is a stainless steel pipe.

[0010] As a further description of the above technical scheme:

[0011] The oil pipe between the oil inlet joint and the outlet joint is wound to form a plurality of annular heating pipe body parts arranged in parallel.

[0012] As a further description of the above technical scheme:

[0013] The outer layer of the annular heating pipe body part is coated with a heat insulation layer, and the heat insulation layer is arranged between the annular heating pipe body part and the high-frequency current coil.

[0014] As a further description of the above technical solution:

[0015] The heat insulation layer is glass fiber heat insulation cotton.

[0016] As a further description of the above technical solution:

[0017] A connection part is provided on the outlet joint.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0019] 1. In the present utility model, the electromagnetic heating type smoke machine heater uses the principle of electromagnetic induction eddy current heating. A high-frequency current wire is wound around a stainless steel oil pipe to form a high-frequency current coil. Under the action of an alternating magnetic field, the stainless steel oil pipe itself generates heat. The traditional cast aluminum heater that generates heat through a heating rod, transfers the heat to the cast aluminum medium, then to the stainless steel oil pipe, and finally to the e-liquid (or water) heat transfer process is cancelled. In this application, the heating efficiency of the heater is higher, and the preheating time is greatly shortened. In addition, there is no high-temperature molten aluminum pouring and solidification process during the production of the heater, and the production process is more environmentally friendly and safe.

[0020] 2. In the present utility model, a stainless steel oil pipe is used as the heating element, and its melting point ≥ 1000 °C, making the electromagnetic heating smoke machine heater have the advantages of a wide operating temperature range, simple structure, short preheating time, and high heating power.

[0028] Embodiment 1

[0029] Please refer to Figures 1-3 , the present invention provides a technical solution: an electromagnetic heating type smoke machine heater, including:

[0030] An oil pipe 1, one end of which is provided with an oil inlet joint 11 and the opposite end is provided with an outlet joint 12. The oil pipe 1 between the oil inlet joint 11 and the outlet joint 12 is wound to form an annular heating tube body 13, and the oil pipe 1 is a steel pipe;

[0031] A high-frequency current coil 2, which is wound outside the annular heating tube body 13.

[0032] The oil pipe 1 is a stainless steel pipe. Using a stainless steel oil pipe as the heating element, its melting point ≥ 1000 °C, making the electromagnetic heating smoke machine heater have the advantages of a wide operating temperature range, simple structure, short preheating time, and high heating power.

[0033] The oil pipe 1 between the oil inlet joint 11 and the outlet joint 12 is wound to form a plurality of annular heating tube bodies 13 arranged in parallel, effectively improving the mass of the liquid medium heated simultaneously and improving the spraying ability of the smoke machine.

[0034] Working principle: The electromagnetic heating type smoke machine heater works on the principle of electromagnetic induction eddy current heating. A high-frequency current wire is wound around the stainless steel oil pipe to form a high-frequency current coil. Under the action of an alternating magnetic field, the stainless steel oil pipe heats itself. Specifically, the smoke raw materials such as smoke oil in the heater are introduced into the annular heating tube body 13 of the oil pipe 1 through the oil inlet joint 11, and the annular heating tube body 13 is convenient for the flow and transportation of the smoke raw materials. The stainless steel oil pipe generates eddy currents under the action of an alternating magnetic field, and heats itself under the action of the eddy currents. The heat is directly transferred to the smoke raw materials, and the smoke raw materials are heated and volatilized and discharged through the outlet joint 12. The traditional cast aluminum heater that heats through a heating rod, transfers the heat to the cast aluminum medium, then to the stainless steel oil pipe, and finally to the smoke oil (or water) is cancelled. The heater in this application has higher heating efficiency and greatly shortened preheating time. In addition, there is no high-temperature molten aluminum pouring and solidification process during the production of the heater, and the production process is more environmentally friendly and safe.

The heat insulation layer 3 is arranged between the annular heating tube body 13 and the high-frequency current coil 2, effectively avoiding heat dissipation and ensuring the heating power of the heater.

[0037] The heat insulation layer 3 is made of fiberglass heat insulation cotton, which is coated on the outer layer of the annular heating tube body 13. The oil inlet joint 11 and the outlet joint 12 pass through the heat insulation layer 3.
