Description

Technical Field

[0001] The utility model relates to the technical field of electric heaters, and more particularly to a single-head heating rod structure used in a stage smoke machine heating system. Background Art

[0002] A stage smoke machine is a device used to generate smoke on various performance stages or in dance halls. It includes a heating system, with a single-ended heating rod as the heating element. The heater consists of a fixed bracket, a single-ended heating rod, a metal tube wrapped around the single-ended heating rod, and a thermocouple. When the single-ended heating rod is powered, the heat generated is transferred to the metal tube in contact with the tube surface, thereby vaporizing the liquid agent and producing a large amount of smoke or steam.

[0003] The metal tube that serves as the heating channel for the atomized preparation is coiled and bonded to the surface of the single-ended heating rod, significantly increasing the heat transfer area and the length of the heating channel, improving heat transfer efficiency. This makes our heating system lightweight and easy to use, and allows for matching heater power to varying smoke volume requirements. A temperature sensor is installed at the smoke outlet to detect the atomization temperature of the atomized preparation, allowing the heating time of the heating source to be adjusted accordingly.

[0004] However, during the installation and maintenance of such single-head heating rods, there is still the problem that the welding points of the thermocouple wires are easy to fall off. In order to overcome this problem, the present invention proposes a single-head heating rod structure for a stage smoke machine heating system. Utility Model Content

[0005] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art and to provide a single-head heating rod structure for a stage smoke machine heating system.

However, it should be understood that these descriptions are only for the purpose of further illustrating the features and advantages of the present invention, and are not intended to limit the patent claims of the present invention. Based on the examples in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0019] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0020] Example 1

[0021] See also Figure 1 and Figure 2 As shown, the present embodiment involves a single-head heating rod structure for a stage smoke machine heating system, comprising a fixed bracket 1, a single-head heating rod 2 being provided on the fixed bracket 1, a first metal tube 3 being wound on the single-head heating rod 2, a thermocouple (not shown) being provided on the first metal tube 3, a wire hole 4 being provided on the fixed bracket 1, a thermocouple wire 5 having one end electrically connected to the thermocouple and the other end welded to the first metal tube being passed through the wire hole 4, a second metal tube 6 also passed through the thermocouple wire 5 being sleeved on the thermocouple wire 5, and the second metal tube 6 being fixed to the fixed bracket 1 by welding.

[0022] Furthermore, the thermocouple wire 5 and the second metal tube 6 sleeved thereon are fixed by buckling.

[0023] Furthermore, the thermocouple wire 5 includes an inner glass fiber insulation layer (not shown) that separately wraps the positive and negative electrode leads, and an outer glass fiber insulation layer (not shown) that wraps both inner glass fiber insulation layers; a glass fiber insulation sleeve (not shown) is further provided outside the outer glass fiber insulation layer.

[0024] Furthermore, the first metal tube 3 and the single-head heating rod 2 are fixed by welding.

[0025] In this embodiment, since the first metal tube 3 and the single-head heating rod 2 are fixed by welding, the second metal tube 6 and the fixed bracket 1 are fixed by welding, and the thermocouple wire 5 and the second metal tube 6 sleeved thereon are fixed by crimping, the welding point position between the thermocouple wire 5 and the first metal tube 3 is not affected by pulling, is not easy to fall off, and is safe and reliable to use.

[0026] The provision of multiple insulating protective layers not only serves as an insulating protection, but also further improves the pull-out resistance of the thermocouple wire 5 , making the lead wire less likely to break.

[0029] Furthermore, a clamping tip 105 for pressing against the single-head heating rod 2 is arranged on the wall of the heating rod installation hole 104 .

[0030] Furthermore, the wire hole 4 is provided on the first bracket side plate 102 .

[0031] In this embodiment, the tube end of the single-head heating rod 2 is inserted into the heating rod mounting hole 104, the wall is pressed and fixed by the surrounding clamping tips 105, and the tube mouth is positioned by the second bracket side plate 103 and then welded and fixed, thereby realizing the overall assembly between the single-head heating rod 2 and the fixed bracket 1.

[0032] And when welding is also adopted between the single-head heating rod 2 and the fixed bracket 1, a rigid connection is formed between the thermocouple wire welding point and the thermocouple wire, the metal tube and the fixed bracket. The welding point position will not shake due to the movement of the connection end of the thermocouple wire, and the reliability is higher.

[0035] In this embodiment, the brazing paste is applied without gap between the first metal tube 3 and the single-head heating rod 2, thereby enhancing the thermal conductivity.

[0036] The single-ended heating rod structure for a stage smoke machine heating system, described in this utility model, utilizes a coiled metal tube in contact with the single-ended heating rod body. The heating source transfers heat through the metal tube, thereby heating the smoke formulation passing through the metal tube and generating smoke. Because the single-ended heating rod has the advantages of small size and high power density, and the coiled metal tube has a long linear contact surface with the heating rod body, the heating source of the entire stage smoke machine heating system features a compact footprint and high efficiency. Furthermore, the design can be diversified to suit different smoke formulations and spray directions, resulting in comprehensive overall functionality and high practicality.
