In current outdoor heating equipment applications, outdoor flameless directional heat energy reflection devices based on infrared radiation technology, especially infrared radiant heaters, are widely used due to their efficient and environmentally friendly heat energy transfer characteristics. However, existing technologies face many problems when these devices are not in operation. The outdoor environment is complex, and dust and debris can easily enter the interior of the infrared radiant heater and accumulate. This not only affects the heat dissipation performance of core components such as heating elements but may also lead to short circuits and other malfunctions, reducing the lifespan and reliability of the equipment. Once a malfunction occurs, it not only increases maintenance costs but may also prevent the device from operating normally and stably when needed, causing inconvenience to users and failing to meet the demand for efficient and stable use of heating equipment in outdoor environments.

Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing infrared radiant heaters, where dust and debris can easily enter the heater when it is not in use, causing accumulation and resulting in poor heat dissipation and short circuits in components such as the heating element. This invention proposes an outdoor flameless directional heat energy reflection device based on infrared radiation technology.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: an outdoor fireless heat energy directional reflection device based on infrared radiation technology, comprising an infrared thermal radiation heater and a heating element.

[0008] The effect achieved by the above components is that, under the action of the torsion spring, the roller is driven to rotate, automatically rolling the dust curtain around its arc surface, thus realizing the convenient rolling up of the dust curtain and making the use of the protective device more flexible and convenient.
[0009] Preferably, the arc surface of the insertion rod is fitted with a spring, and the two ends of the spring are fixedly connected to the fixing plate and the pull plate, respectively.
[0010] The effect achieved by the above components is that, under the action of the spring, the insertion rod automatically rebounds and inserts into the insertion hole of the limiting plate, and can firmly fix the insertion rod in the predetermined position, thereby improving the practicality of the device.
[0011] Preferably, the surface of the limiting block is fixedly connected to two extension plates, and a handle is fixedly connected to the side of the two extension plates that are close to each other.
[0012] The effect achieved by the above-mentioned components is that by setting up a handle, a better point of leverage is provided for pulling the dust curtain. Compared with directly pulling the surface of the dust curtain, the handle is more labor-saving, making the opening and closing of the dust curtain easier and less strenuous, and reducing the difficulty of operation.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, this utility model provides a technical solution: an outdoor fireless heat energy directional reflection device based on infrared radiation technology, including an infrared radiant heater 1 and a heating element 2. The heating element 2 is installed inside the infrared radiant heater 1, and a protective device 3 is provided on the surface of the infrared radiant heater 1. By setting the protective device 3, dust, debris, etc. can be effectively prevented from entering the interior of the infrared radiant heater 1 when it is not working, thereby reducing the occurrence of malfunctions, extending its service life, and preventing dust, debris, etc. from entering the interior of the infrared radiant heater 1 when it is not working. To prevent the accumulation of debris, which can lead to poor heat dissipation and short circuits in components such as the heating element 2, a support device 4 is provided on the surface of the infrared radiant heater 1 to ensure its normal and stable operation when needed. This provides a stable support for the infrared radiant heater 1, preventing it from tipping over due to collisions or other factors. This reduces damage and safety hazards caused by accidental tipping and avoids electrical faults such as leakage caused by collisions or external interference, which could lead to fires caused by high-temperature components coming into direct contact with flammable materials.
[0032] The specific setup and function of its protective device 3 and supporting device 4 will be explained below.
[0033] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown in this embodiment: the protective device 3 includes a fixing frame 301, which is fixedly connected to the surface of the infrared thermal radiation heater 1. A round rod 302 is fixedly connected to the inner wall of the fixing frame 301. A roller 303 is rotatably connected to the arc surface of the round rod 302. A dustproof curtain 305 is fixedly connected to the arc surface of the roller 303. A limit block 306 is fixedly connected to the surface of the dustproof curtain 305. A limit plate 307 is fixedly connected to the surface of the limit block 306. An insertion hole is provided on the surface of the infrared radiant heater 1. A fixing plate 308 is fixedly connected to the surface of the infrared radiant heater 1. An insertion rod 309 is slidably inserted into the fixing plate 308. The insertion rod 309 is slidably connected to the inner wall of the insertion hole of the limiting plate 307. A pull plate 310 is fixedly connected to one end of the insertion rod 309. Two torsion springs 304 are sleeved on the arc surface of the round rod 302. The two ends of the torsion springs 304 are fixedly connected to the fixing frame 301 and the scroll 303 respectively. Under the action of the torsion springs 304, the scroll can be driven. Rotation of 303 automatically winds the dust curtain 305 around its arc surface, achieving convenient winding of the dust curtain 305 and making the protective device 3 more flexible and convenient to use. The arc surface of the insertion rod 309 is fitted with a spring 311, and the two ends of the spring 311 are fixedly connected to the fixing plate 308 and the pull plate 310 respectively. Under the action of the spring 311, the insertion rod 309 is automatically pushed back and inserted into the insertion hole of the limiting plate 307, and the insertion rod 309 is firmly fixed in the predetermined position, improving the practicality of the device. Two extension plates 312 are fixedly connected to the surface of the limiting block 306, and a handle 313 is fixedly connected to the side of the two extension plates 312 that are close to each other. By setting the handle 313, a better point of force is provided for pulling the dust curtain 305. Compared with directly pulling the surface of the dust curtain 305, the handle 313 is more labor-saving, making the unfolding and retraction of the dust curtain 305 easier and less labor-saving, and reducing the difficulty of operation.
[0034] Reference Figure 7 , Figure 8 and Figure 9As shown, specifically, the support device 4 includes a groove 401, which is formed on the surface of the infrared radiant heater 1. A rotating shaft 402 is fixedly connected to the inner wall of the groove 401. A support frame 403 is rotatably connected to the arc surface of the rotating shaft 402. A round shaft 404 is fixedly connected to the inner wall of the groove 401. A support plate 405 is rotatably connected to the arc surface of the round shaft 404. A slot 406 is formed on the surface of the support plate 405. The support frame 403 is slidably connected to the inner wall of the slot 406. A slot 407 is formed on one side of the support frame 403. A round groove 408 is formed on one side of the support plate 405. A threaded rod 409 is threaded into the inner wall of the infrared radiant heater 1. The threaded surface of the threaded rod 409 is connected to the slot 407. 07. Threaded connection: The infrared radiant heater 1 has a drive rod 410 inserted into its internal thread. The threaded surface of the drive rod 410 is threadedly connected to the circular groove 408, which achieves the effect of folding and fixing the support frame 403 and the support plate 405. When not in use, it does not occupy extra space and is easy to store and carry, thus improving the convenience of the device. The support plate 405 and the bottom surface of the infrared radiant heater 1 are both fixedly connected with anti-slip pads 411. The anti-slip pads 411 are made of rubber. By setting the anti-slip pads 411, a large friction force is generated when in contact with the placement surface, so that the infrared radiant heater 1 can firmly grip the ground and ensure that the heater always maintains a stable position during use.
[0035] Working principle: When the infrared radiant heater 1 is idle and the protective device 3 is needed, pull the handle 313 on the extension plate 312 of the limiting block 306 to unfold the dust curtain 305 from the roller 303 and cover the surface of the infrared radiant heater 1. At this time, the torsion spring 304 will store the force under torsion. After the dust curtain 305 is unfolded to the appropriate position, align the insertion hole on the limiting plate 307 with the insertion rod 309 on the fixing plate 308, release the pull plate 310, and the insertion rod 309 will automatically insert into the insertion hole under the elastic force of the spring 311, thus fixing the dust curtain 305. If it is necessary to retract the dust curtain 305, pull the pull plate 310 to overcome the elastic force of the spring 311 and retract the insertion rod 309. When rod 309 is pulled out of the socket, the torsion spring 304 on the arc surface of rod 302 releases its elastic potential energy due to previous stretching, causing the roller 303 to rotate automatically and roll up the dust curtain 305 onto the roller 303 for storage. By setting up the protective device 3, dust and debris can be effectively blocked from entering the interior of the infrared radiant heater 1 when it is not working, reducing the occurrence of malfunctions and extending its service life. This avoids the accumulation of dust and debris inside the infrared radiant heater 1 when it is not working, which can lead to poor heat dissipation and short circuits in components such as heating element 2, ensuring that it can operate normally and stably when needed.
[0036] When the support device 4 is needed, rotate the threaded rod 409 to allow it to rotate out of the slot 407 of the support frame 403. Then rotate the drive rod 410 to allow it to rotate out of the circular groove 408 of the support plate 405. Move the support plate 405 to rotate on the arc surface of the circular shaft 404, and then remove it from the groove 401. After rotating it to the appropriate position, push the support frame 403 to rotate on the rotating shaft 402, so that it inserts into the slot 406 on the surface of the support plate 405 to achieve support and positioning. When it is necessary to retract the support frame 403 and the support plate 405, repeat the above operations in reverse to complete the retraction. The support device 4 facilitates the storage of the infrared radiant heater 1. When the support device 4 is in operation, the anti-slip pad 411 will contact the placement surface, and its surface texture will increase the friction to prevent the infrared radiant heater 1 from sliding due to external force or its own weight. By setting the support device 4, a stable support is provided for the infrared radiant heater 1, making it less likely to tip over due to collisions or other factors. This reduces damage and safety hazards caused by accidental tipping, and avoids electrical faults such as leakage caused by the infrared radiant heater 1 tipping over due to collisions or external interference, which could lead to fires caused by high-temperature components coming into direct contact with flammable materials.
