Description

Technical Field

[0001] The utility model relates to an electric heater, in particular to a high-efficiency heater. Background Art

[0002] The utility model patent discloses a bird cage heater (201721350279.1), comprising a main body (1) and a heating component fixed on the main body (1), the heating component is provided with a bird cage-shaped outer protective cover (2) with a bottom end fixed on the upper part of the main body (1), characterized in that: the heating component comprises a carbon crystal plate heating element (10) reversely mounted on the upper part of the main body (1), an inner protective cover (3) with a bottom end fixed on the upper part of the main body (1) is provided between the carbon crystal plate heating element (10) and the outer protective cover (2), the inner protective cover (3) is provided with a top plate (8) on the top, and a conical reflector (9) with a tip facing downward is provided at the bottom of the top plate (8), see Figure 1 As shown, its advantage is that it can dissipate heat from bottom to top and then use the conical reflector to dissipate heat to the surroundings, thereby increasing the service life of electronic devices. The disadvantage is that the conical reflector seals the top of the inner protective cover, so that the hot air cannot circulate at the top, which seriously affects the use effect. Summary of the invention

[0018] like Figure 2 As shown, a high-efficiency heater includes a base 11, a heating component 12 and an outer protective net 13 arranged on the base 11, and an inner protective net 14 is arranged between the heating component 12 and the outer protective net 13;

[0019] A reflective component 15 is provided on the outer protective net 13 , and a portion of the reflective component 15 extends into the inner protective net 14 ; there is a gap between the reflective component 15 and the top of the inner protective net 14 .

[0020] When in use, the heat generating component 12 emits heat upward, the reflective component 15 dissipates heat to the surroundings, and the hot gas in the inner protective net 14 is dissipated outward through the gap, thereby improving the heating effect. Figure 1 In terms of the temperature, it can be increased by 0.4 degrees Celsius in 10 minutes. The existing technology affects the heating effect due to the blocking effect of the inner protective net, and the heat is more concentrated on the inner protective net. Although the removal of the inner protective net can reduce the barrier to heat dissipation, it is necessary to protect the heating component 12, that is, the base needs to be made very large, and because there is no heat storage function of the inner protective net, the heat dissipation effect is easily affected by the surrounding wind direction.

[0021] like Figure 3 As shown, a high-efficiency heater includes a base 11, a heating component 12 and an outer protective net 13 arranged on the base 11, and an inner protective net 14 is arranged between the heating component 12 and the outer protective net 13;

[0022] The reflective component 15 is connected to the inner protective net 14 through a connecting piece (generally a connecting rod), and the reflective component 15 partially extends into the inner protective net 14; there is a gap between the reflective component 15 and the top of the inner protective net 14.

[0023] Preferably, the heating component 12 is one of a carbon crystal disk heating element and a heating tube.

[0024] Preferably, the surface of the inner protection net 14 is coated with graphene material to improve the radiation effect of the inner protection net 14 .

[0025] like Figure 4 As shown, a handle 16 is provided on the upper portion of the outer protective net 13 , and the handle 16 passes through the outer protective net 13 and is connected to the reflective component 15 .

[0026] Preferably, the handle 16 can rotate relative to the outer protective net 13. Generally, a rotating shaft is provided on the outer protective net 13, and the rotating shaft can rotate relative to the outer protective net 13. The handle 16 is connected to the reflective component 15 via the rotating shaft. The reflective component 15 and the handle 16 can rotate together. The reflective surface of the reflective component 15 can be set in one direction. Rotating the handle 16 can rotate the reflective component 15 so that its reflective surface faces a fixed direction, so that the heater can be placed under the office desk for warming the feet.
