DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of the utility model.

[0027] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the utility model.

[0028] See also Figures 1 to 6 , Figure 4 The embodiment of the present invention provides a heater 10, which includes a housing 100, a heating element 200, a protective net 300, and a first thermal insulation member 400. The housing 100 has a mounting frame 110, the heating element 200 is mounted in the housing 100, the protective net 300 is connected to the mounting frame 110 and is exposed outside the housing 100, the protective net 300 is arranged opposite to the heating element 200, and the first thermal insulation member 400 is mounted in the housing 100. The first thermal insulation member 400 includes a first thermal insulation portion 410 and a second thermal insulation portion 420 connected to each other. The first thermal insulation portion 410 is connected to the heating element 200 and is located above the heating element 200, and the second thermal insulation portion 420 is in contact with the protective net 300 and is spaced apart from the heating element 200. In this way, the first thermal insulation part 410 is located above the heating element 200, and can directly block a portion of the rising hot air flow generated by the heating element 200, which reduces the amount of heat flowing directly upward, and the design of the second thermal insulation part 420 requires the hot air flow to pass through a longer path during the rising process, so that the heat has more time and opportunities to dissipate into the air instead of being concentrated on the surface of the shell 100, thereby helping to reduce the temperature of the outer surface of the shell 100 and reducing the risk of deformation or damage due to high temperature.

[0029] In some embodiments, the height of the second thermal insulation portion 420 is 4 mm to 6 mm. The second thermal insulation board may be, but is not limited to, 4 mm, 4.5 mm, 5 mm, 5.5 mm, or 6 mm. Thus, the height of the second thermal insulation portion 420 is 4 mm to 6 mm, effectively extending the flow path of the thermal airflow. This design requires the heat to travel a longer distance during its rise, increasing the contact time and area between the thermal airflow and the surrounding air, and helping to more evenly distribute the heat throughout the interior space.

[0030] Furthermore, if the height of the second heat insulating portion 420 is too small, the airflow path will not be significantly extended, and the upward transfer of heat will not be effectively reduced, resulting in the surface of the housing 100 still being susceptible to overheating. If the height of the second heat insulating portion 420 is too large, it may block the heating element 200, affecting its normal heat radiation and convection effects.

[0031] In some embodiments, the first thermal insulation portion 410 is spaced apart from the top 111 of the mounting frame 110. This spacing provides additional space for hot air flow, facilitating natural convection. Hot air can rise within this space and be exhausted through vents or other heat dissipation structures in the top 111 of the housing 100, thereby dissipating heat more efficiently.

[0032] Additionally, the spacing allows heat to flow upward over a longer path, increasing the time it spends in contact with the surrounding air and helping to disperse heat more evenly throughout the interior space.

[0033] In some embodiments, the heater 10 further includes a heat sink 500 connected between the first insulating portion 410 and the top 111 of the mounting frame 110. The heat sink 500 is typically made of a highly thermally conductive material (such as aluminum or copper) that rapidly absorbs and conducts heat. Connecting the heat sink 500 between the first insulating portion 410 and the top 111 of the mounting frame 110 more effectively transfers heat generated by the heating element 200 to the exterior, thereby accelerating heat dissipation.

[0034] Furthermore, the larger surface area of ​​the heat sink 500 helps to evenly distribute the heat over a larger area. This can reduce the risk of local overheating and allow the heat to be dissipated more evenly into the surrounding air.

[0035] In some embodiments, the heat sink 500 is provided with a plurality of heat dissipation holes 510, which are spaced apart along the length of the heat sink 500. Thus, the presence of the heat dissipation holes 510 provides more channels for hot air flow, promoting air convection. Hot air can flow upward and be discharged more quickly through these holes, thereby improving heat dissipation efficiency.

[0036] In addition, the plurality of heat dissipation holes 510 are arranged in sequence along the length of the heat sink 500, which helps to distribute heat more evenly over the entire surface of the heat sink 500. This can avoid local overheating and allow heat to be dissipated more evenly into the surrounding air.

[0037] In some embodiments, the heater 10 further includes a second thermal insulator 600, which is mounted between the heat sink 500 and the top 111 of the mounting frame 110. Thus, the second thermal insulator 600 is located between the heat sink 500 and the top 111 of the mounting frame 110, effectively isolating heat transferred from the heat sink 500 to the top 111 of the mounting frame 110, thereby reducing the surface temperature of the housing 100.

[0038] Furthermore, by providing a second thermal insulator 600 between the heat sink 500 and the top 111 of the mounting frame 110, heat can be prevented from concentrating in the top 111 of the mounting frame 110, thereby avoiding local overheating. This helps maintain a uniform surface temperature of the housing 100, thereby improving the safety and comfort of the heater 10.

[0039] In some embodiments, the heater 10 further includes a reflector 700, which is spaced apart from and opposite to the heating element 200. The reflector 700 can reflect heat toward the protective screen 300, where it is dissipated into the indoor space. The reflector 700 is typically made of a highly reflective material (such as aluminum or stainless steel) to effectively reflect infrared radiation emitted by the heating element 200. This allows more heat to be reflected toward the protective screen 300 rather than dissipated in other directions.

[0040] Furthermore, since the reflector 700 focuses the heat onto the protective net 300, it reduces heat loss to the rear or in non-target directions, ensuring that more heat is directed forward, thereby improving energy efficiency. This is very important for saving energy and reducing operating costs.

[0041] In some embodiments, the reflector 700 is curved, with the inner curved surface of the reflector 700 facing the heating element 200 and the protective net 300. This design of the curved reflector 700 can more effectively focus the heat emitted by the heating element 200 and reflect it onto the protective net 300. With the inner curved surface facing the heating element 200 and the protective net 300, it can better capture and concentrate the heat, allowing it to be more effectively transferred to the indoor space.

[0042] In some embodiments, the heater 10 further includes a third thermal insulator 800 , which is connected to the bottom 112 of the heating element 200 and positioned between the heating element 200 and the bottom 112 of the mounting frame 110 . Thus, the third thermal insulator 800 , positioned at the bottom 112 of the heating element 200 , effectively isolates heat from the heating element 200 and from the mounting frame 110 at the bottom 112. This reduces the risk of heat being directly transferred through the mounting frame 110 to the bottom 112 of the housing 100 , thereby lowering the temperature of the bottom 112 of the housing 100 .

[0043] In some embodiments, the first thermal insulator 400 is a metal thermal insulator, for example, made of copper, iron, or other materials. Metal materials have high temperature resistance and can remain stable in high-temperature environments for extended periods, resisting deformation or damage. This extends the service life of the first thermal insulator 400 and ensures its reliability during long-term use.

[0044] In some embodiments, the housing 100 is generally made of plastic, and the protective net 300 is generally a metal protective net 300. The protective net 300 is also provided with through holes so that the heat generated by the heating element 200 can be dissipated into the room through the through holes.
