[0028] The present invention will now be described in further detail through specific embodiments and in conjunction with the accompanying drawings.

[0029] like Figures 1 to 5 As shown, this embodiment provides an electric heater installed under a table, including a housing 1, an annular heating element 2, and a motor 3. The annular heating element 2 provides heating. A first air inlet 101 is provided on the surface of the housing 1, and multiple air outlets 102 are provided around the housing 1. The motor 3 is located at the bottom of the first air inlet 101 and inside the annular heating element 2. A guide wheel 4 is installed on the motor 3, and the guide wheel 4 is located inside the annular heating element 2. A guide vane 41 is provided on the guide wheel 4. Air enters the housing 1 from the first air inlet 101, and the motor... The rotation of 3 drives the air guide wheel 4 to rotate, and the rotation of the air guide plate 41 blows air from the center outward to the annular heating element 2, thus generating hot air. The hot air is discharged from the outer air outlet 102. The annular heating element 2 includes an annular mica sheet 21 and a heating wire 22. The heating wire 22 is installed and fixed around the annular mica sheet 21. The use of the annular mica sheet 21 and the heating wire 22 as a whole annular heating element 2 can reduce the volume, and the vertical arrangement can increase the heat dissipation area. This structure has a small volume, does not take up space, is easy to install and has low cost.

[0030] Furthermore, a heat insulation plate 11 is provided inside the outer shell 1. The heat insulation plate 11 can reduce the heat dissipation from the top and bottom. The temperature of the outer shell after the heat insulation plate 11 is installed will not increase. An overheated outer shell is prone to damaging the table when it comes into contact with it. A first through hole 111 is provided on the heat insulation plate 11, and a second air inlet 103 is provided on the outer shell 1. The first through hole 111 and the second air inlet 103 are located in adjacent positions. Air enters from the second air inlet 103, passes through the first through hole 111, and reaches the air guide wheel 4.

[0031] Furthermore, an air intake frame 12 is installed on the second air inlet 103. The surface and periphery of the air intake frame 12 are covered with multiple third air inlets 121. The air intake frame 12 can form a three-dimensional state, which increases the air intake capacity of the peripheral third air inlets 121.

[0032] Furthermore, multiple rows of fourth air inlets 104 are provided around the second air inlet 103, which can increase the air intake capacity.

[0033] Furthermore, the second air inlet 103, the first through hole 111, the motor 3, and the first air inlet 101 are on the same axis, which makes the air intake smoother and unobstructed.

[0034] Furthermore, a plurality of support rods are provided between the annular heating element 2 and the outer shell 1, the support rods being used to support and fix the annular heating element 2.

[0035] Furthermore, an air guide plate 112 is provided around the heat insulation plate 11. The air guide plate 112 is longitudinally positioned at the corner of the outer shell 1. When the outer shell has a square appearance, there are four corners. Installing the air guide plate 112 at the four corners can reduce the impact of the wind on the corners and reduce wind noise. The air guide plate 112 will guide the wind to the air outlet 102 on both sides for discharge.

[0036] Furthermore, the outer casing 1 includes a housing 13 and a cover 14. The cover 14 covers the housing 13, the first air inlet 101 and the air outlet 102 are located on the housing 13, and the second air inlet 103 is located on the cover 14.

[0037] like Figures 6 to 7 As shown, this embodiment provides an electric heating table. In the first aspect, the utility model provides an electric heater installed on the bottom of the table, including an electric heating table body 5. The bottom of the electric heating table body 5 is provided with a second through hole 51. The electric heater is installed on the second through hole 51. The first air inlet 101 is aligned with the second through hole 51 and installed, and enters the first air inlet 101 through the second through hole 51.

[0038] Existing electric heaters use vertical heating elements, requiring a large outer casing to cover them and avoid safety hazards. This results in heaters that are too bulky, taking up too much space and making them impossible to install on the bottom of a table. Furthermore, their complex structure and high cost contribute to their problem. To address this, a new design is implemented using a ring-shaped heating element 2. The outer casing 1 has a first air inlet 101 on its surface and multiple air outlets 102 around it. A motor 3 is equipped with a guide wheel 4, which has guide vanes 41. The rotation of the motor 3 drives the guide wheel 4, and the guide vanes 41 rotate, blowing air from the center outwards through the ring-shaped heating element 2. This generates hot air, which is then exhausted through the outer air outlets 102. This structure reduces volume, and the vertical arrangement increases the heat dissipation area. This design is compact, space-saving, easy to install, and cost-effective.

[0039] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
