Please refer to FIGS. 1 and 2 which are the preferred embodiment of the present invention. The electric heater includes a reflector 210 and a first heat generating member 220 for heating air. A first air passage 140 is installed on the back surface of the reflector 210 and has an air intake port 111 at one end, and the first air passage 140 is for generating wind. A power module 300 communicating with the other end of the first air passage 140, and a second air passage 150 having one end communicating with the air blowing side of the power module 300 and the other end provided with an air blowing port 121. include.

The heat generated by the first heat generating module 200 can be radiated forward and also can be emitted from the air outlet 121 by the power module 300, so that the heat can be received in a farther space. The electric heater has the advantages of energy saving, wide radiation range and diversification of functions. Each of the above components will be described in further detail below.

In a preferred embodiment of the present invention, the electric heater mainly includes a housing module 100, a first heat generating module 200 and a power module 300. The first heating module 200 is fixedly installed in the housing module 100 and the power module 300 is installed in the housing module 100 .

Specifically, the housing module 100 mainly includes a rear housing 110 and a front housing 120, as shown in FIG. As shown in FIG. 2, an air inlet 111 is opened in the upper half of the rear housing 110 . Preferably, the air inlet 111 is fitted with a removable filter net (not shown). A blower port 121 is formed in the lower half of the front housing 120 . Preferably, the blower port 121 is equipped with a blower grill (not shown).

Housing module 100 further includes protective cover 130 . The protective cover 130 is covered with the reflector 210, which will be described later.

The first heat generating module 200 specifically includes a reflector 210, a first heat generating member 220 and a first fixing device (not shown).

Specifically, the first heat generating member 220 is mounted in front of the reflector 210 by a first fixing device. The reflector 210 is used to radiate the heat generated by the first heat generating member 220 forward. That is, the heat generated by the first heat generating member 220 is reflected by the reflector 210 after being radiated to the reflector 210 .

The reflector 210 has an arc shape. The specific number of arcs matches the number of the first heat generating members 220 . Specifically, when the number of the first heat generating members 220 is one, the reflector 210 has a 'C' shape. Also, as shown in FIG. 1, when the number of the first heat generating members 220 is two, the reflector 210 has a 'W' shape. The first heat generating member 220 is preferably a heat generating tube such as a graphite tube, quartz tube, carbon tube, halogen tube, or the like.

The rear housing 110 and the reflector 210 surround the first air passage 140 . The first air passage 140 is installed vertically. That is, the wind in the first air passage 140 flows vertically.

As shown in FIG. 1 , the first air passage 140 has the intake port 111 at one end and communicates with the intake side of the power module 300 at the other end. That is, the power module 300 is installed below the first air passage 140 . Specifically, the power module 300 includes a first power device (not shown), a fan 320 and a volute 330 . The output end of the first power unit is fixedly connected to the fan 320 and used to rotate the fan 320 to generate wind. The fan 320 is mounted within the volute 330 . The volute 330 can guide the wind from the first air passage 140 to the second air passage 150 . The power module 300 can transfer the heat inside the main body generated by the operation of the first heat generating member 220 to a longer and wider distance through the air outlet 121 at the lower end.

When the first heat generating member 220 generates heat, the lower power module 300 is simultaneously operable. As a result, the power module 300 emits the heat generated by the upper first heat generating member 220 from the fan grill, thereby further extending the heat receiving area.

In another preferred embodiment of the present invention, the electric heater further comprises a second heating module 400 for further heating the hot air. As shown in FIG. 2, the second heat generating module 400 is installed in the air outlet 121, and specifically includes a second heat generating member 410 and a second fixing device (not shown). The second heat-generating member 410 is mounted on the air outlet 121 by a second fixing device. The second heat generating member 410 is preferably a PTC heat generating member. Since the electric heater generates heat by combining the first heat generating member 220 and the second heat generating member 410, the heat can be radiated to a longer distance and a wider space.

In another preferred embodiment of the present invention, as shown in FIG. 1, the electric heater further comprises a rotating structure 500 for swinging the first heat generating member 220 and the power module 300 left and right, a bottom base; 610 and an intermediate bearing plate 620 .

Specifically, as shown in FIG. 1 , the rotating structure 500 includes a second power device 510 and a transmission mechanism 520 . The output end of the second power device 510 is connected to the transmission mechanism 520 , and the transmission mechanism 520 is mounted on the bottom base 610 . Preferably, the second power device 510 is a motor. More specifically, the transmission mechanism 520 includes a driving gear 521 and a driven gear 522 that mesh with each other. The driving gear 521 is fixedly connected to the output end of the second power unit 510 , and the driven gear 522 is fixedly mounted on the bottom base 610 .

The intermediate support plate 620 is installed coaxially with the bottom base 610 . The first heat generating module 200 , the power module 300 and the second power unit 510 are all installed on the intermediate support plate 620 . When the second power unit 510 operates, the intermediate support plate 620 and each member installed on the intermediate support plate 620 are swung left and right with respect to the bottom base 610 .

The rotating structure 500 allows the electric heater to have a rotating function. When the upper first heat generating module 200 and the second heat generating module 400 are operated, the rotating structure 500 is simultaneously operated to achieve a swinging function, thereby allowing heat to be radiated to a wider area. This structure effectively utilizes the heat generated by the first heat generating member 220 so that the user can feel the heat radiated farther and wider from the product.

The above is only a preferred embodiment of the present invention, and many modifications can be made by those skilled in the art within the scope of specific embodiments and applications based on the idea of the present invention. Moreover, all of these modifications are within the scope of protection of the present invention as long as they do not deviate from the idea of the present invention.
