[0017] Reference Figure 1-3 The utility model proposes a direct heating electric heater, including an upper seat body 1, a lower seat body 2, a heating element 3, a protective net 4, and an outer shell 5. The heating element 3 and the protective net 4 are both vertically fixedly installed between the upper seat body 1 and the lower seat body 2, and the heating element 3 is located in the protective net 4. The outer shell 5 is installed between the upper seat body 1 and the lower seat body 2 and coaxially sleeved outside the protective net 4. The outer shell 5 has an air outlet channel 6 extending vertically and with an adjustable width.
[0018] During use, the user can adjust the size of the air outlet channel 6 according to the use requirements, thereby adjusting the heat dissipation.
[0019] The outer shell 5 is made of heat-insulating material, and a fan (not shown in the figure) is installed on the upper body 1 or the lower body 2.
[0020] Specifically, in order to achieve adjustable width of the air outlet channel 6, the outer shell 5 includes a first plate body 51, a second plate body 52 and a third plate body 53. The first plate body 51, the second plate body 52 and the third plate body 53 are all arc-shaped, and the three are coaxially arranged with the protective net 4. The second plate body 52 and the third plate body 53 are respectively slidably installed on both sides of the first plate body 51, and an air outlet channel 6 is formed between the second plate body 52 and the third plate body 53 away from the two sides of the first plate body 51.
[0021] Specifically, the width of the air outlet channel 6 is adjusted by sliding the second plate 52 and the third plate 53 along the width direction of the air outlet channel 6, and the angle of the air outlet channel 6 can be changed according to the different moving distances of the second plate 52 and the third plate 53. In addition, when the two sides of the second plate 52 and the third plate 53 are in contact, the air outlet channel 6 is closed, and the heating element 3 and the protective net 4 are stored in the housing 5. When the electric heater is not in use, the air outlet channel 6 can be closed to isolate the heating element 3 from the outside air, so as to avoid the accumulation of dust and impurities when the heating element 3 is not used for a long time. For details, refer to Figure 2 .
[0022] In order to expand the maximum width of the air outlet channel 6 as much as possible, the second plate body 52 is composed of a plurality of first plate bodies 521 that are sequentially connected in a sliding manner along the circumferential direction thereof, and one of the plurality of first plate bodies 521 located at the front end is connected to the inner wall of the first plate body 51 in a sliding manner along the circumferential direction thereof, and the third plate body 53 is composed of a plurality of second plate bodies 531 that are sequentially connected in a sliding manner along the circumferential direction thereof, and one of the plurality of second plate bodies 531 located at the front end is connected to the outer wall of the first plate body 51 in a sliding manner along the circumferential direction thereof, for specific reference. Figure 4 At this time, the first plate body 51, the plurality of first plate body parts 521, and the plurality of second plate body parts 531 are sequentially stacked in the radial direction, and at this time, the width of the air outlet channel 6 is the largest.
[0023] The second plate body 52 also has a first connection portion 522 extending radially outward on the side wall of the air outlet channel 6, and the third plate body 53 also has a second connection portion 532 extending radially outward on the side wall of the air outlet channel 6, and the first connection portion 522 can be attached to the second connection portion 532 and fixed by bolts.
[0024] The upper seat 1 and the lower seat 2 also have a rotating part 21 that rotates coaxially therewith. The first plate 51 is detachably installed between the two rotating parts 21. When the first plate 51 is removed from the rotating part 21, the heating element 3 is unobstructed on all sides and can transport heat outward at 360 degrees.
[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
