[0002] At present, the far-infrared electric heater includes a far-infrared heating tube and a reflective cover. The far-infrared heating tube can be a carbon fiber heating tube. The far-infrared heating tube is arranged on the front side of the reflective cover (as a concave mirror), so the far-infrared rays emitted forward by the far-infrared heating tube directly irradiate forward, while the far-infrared rays emitted backward by the far-infrared heating tube are reflected forward by the reflective cover. The far-infrared electric heaters on the market are usually equipped with a left and right shaking function. Although the range of people or objects that can be irradiated by far-infrared rays is increased, the heating is intermittent, because after a short sweep of a person or object, the person or object needs to wait for a long time before being irradiated again. The actual heating effect of several people within a certain angle range is relatively poor. Especially when it is necessary to dry clothes within a certain range, after the clothes at a certain position are briefly heated, because the far-infrared electric heater shakes its head and swings away, the heat of the above clothes cannot be accumulated, resulting in a very slow drying speed of the clothes, causing energy waste.

DETAILED DESCRIPTION
[0025] The utility model is further described below in conjunction with the accompanying drawings.
[0026] The far-infrared electric heater with adjustable heating range of the utility model is as follows: Figure 1 , Figure 2 and Figure 6 As shown, it includes a base 1, and the upper side of the base 1 is provided with a fixed heating component 2, a left swing heating component 3 and a right swing heating component 4. The fixed heating component 2 is located between the left swing heating component 3 and the right swing heating component 4. In other words, the fixed heating component 2 is located in the middle position of the far-infrared electric heater in the left and right directions. The lower end of the fixed heating component 2 is fixedly connected to the base 1, and the lower end of the left swing heating component 3 is horizontally connected to the base 1. In other words, the swing axis of the left swing heating component 3 is a vertical axis, and the lower end of the right swing heating component 4 is horizontally connected to the base 1. Figure 4 and Figure 6 As shown, the fixed heating component 2 is provided with a fixed far-infrared heating tube 201 and a middle reflector 202, and the fixed far-infrared heating tube 201 is arranged on the front side of the middle reflector 202; the fixed heating component 2 also includes a fixed shell component, and the fixed far-infrared heating tube 201 and the middle reflector 202 are both arranged in the fixed shell component, so specifically, the lower end of the above-mentioned fixed shell component is fixedly connected to the base 1 through corresponding screws; the front part of the above-mentioned fixed shell component is also provided with a fixed mesh cover, and the fixed mesh cover is located on the front side facing the middle reflector 202. It should be noted that Figure 4 The above-mentioned fixed mesh cover is not shown. Figure 4 and Figure 6 As shown, the left swinging heating component 3 includes a left far-infrared heating tube 301 and a left reflecting cover 302, and the left far-infrared heating tube 301 is arranged on the front side of the left reflecting cover 302. The right swinging heating component 4 includes a right far-infrared heating tube 401 and a right reflecting cover 402, and the right far-infrared heating tube 401 is arranged on the front side of the right reflecting cover 402. The fixed far-infrared heating tube 201, the left far-infrared heating tube 301 and the right far-infrared heating tube 401 are respectively arranged upright.
[0027] like Figure 4 As shown, the fixed heating component 2, the left swing heating component 3 and the right swing heating component 4 are all irradiating far infrared rays forward. In this working state, the irradiation and heating range of the electric heater of the utility model is small and relatively concentrated; when the irradiation range needs to be adjusted, such as Figure 5 As shown, the left swinging heating component 3 is swung to the left (clockwise) by hand, so that the left swinging heating component 3 is changed to irradiate the left front, and the right swinging heating component 4 is swung to the right by hand, so that the right swinging heating component 4 is changed to irradiate the right front, while the fixed heating component 2 maintains irradiating straight ahead, so that the far-infrared electric heater of the utility model is changed to a dispersed irradiation state, and the irradiation range of the far-infrared electric heater of the utility model is increased, so that people located in the left front, straight front and right front of the far-infrared electric heater of the utility model can get the heating effect at the same time, and the far-infrared irradiation effect of the far-infrared electric heater of the utility model on people is continuous, so that people do not feel hot and cold; in Figure 5In the state shown, the far-infrared electric heater of the present invention can be used to irradiate a row of clothes (arranged in the left and right directions) hung in front of the far-infrared electric heater, so that the far-infrared electric heater of the present invention continuously irradiates the row of clothes hung, which is beneficial for continuously heating clothes in a larger range, saving time for drying clothes, and saving energy; when only one person or object needs to be heated, the electric heater of the present invention can be adjusted back to Figure 4 The state shown, so the electric heater of the utility model can heat a person or a single object more concentratedly, which is conducive to the rapid heating of the person or object. Of course, the right swing heating component 4 can be swung to the right, or the left swing heating component 3 can be swung to the left, which is conducive to the convenient and flexible use of the far-infrared electric heater. From the above, it can be seen that the left swing heating component 3 can be understood as "a component with an independent heating tube located in the left position that can swing to adjust the irradiation direction".
[0028] Furthermore, if Figure 1 , Figure 2 and Figure 6 As shown, the electric heater of the utility model also includes an upper cover plate 5, and the fixed far-infrared heating tube 201, the left far-infrared heating tube 301 and the right far-infrared heating tube 401 are all arranged below the upper cover plate 5. The upper cover plate 5 is fixedly connected to the fixed heating component 2 through corresponding screws, and the upper end of the left swing heating component 3 is rotatably connected to the upper cover plate 5, and the upper end of the right swing heating component 4 is rotatably connected to the upper cover plate 5. Therefore, the upper cover plate 5 radially positions the left swing heating component 3 and the right swing heating component 4 respectively to prevent the upper end of the left swing heating component 3 and the upper end of the right swing heating component 4 from shaking. Figure 1 and Figure 6 As shown, a left handle 31 and a right handle 41 are provided on the upper side of the upper cover plate 5, the lower end of the left handle 31 is relatively fixedly connected to the left swing heating component 3, and the lower end of the right handle 41 is relatively fixedly connected to the right swing heating component 4, so when the user needs to swing the left swing heating component 3 to adjust the position, the user pinches the left handle 31 with his hand, and rotates the left handle 31 to synchronously drive the left swing heating component 3 to swing and adjust the position, avoiding the user's need to grasp the part of the left swing heating component 3 corresponding to the height position of the left far-infrared heating tube 301 with his hand, thereby avoiding scalding the hand, and because the left handle 31 is located at the top position of the far-infrared electric heater, when the far-infrared electric heater is placed on the ground for use, the user can also operate the left handle 31 more conveniently with his hand. The functional principle of the right handle 41 is the same as that of the left handle 31.
[0029] Furthermore, if Figure 1 , Figure 2 and Figure 6As shown, a gear knob 21 is provided on the upper side of the upper cover plate 5, and a gear rotary switch 22 is provided in the upper part of the fixed heating component 2. The gear rotary switch 22 belongs to the prior art. The gear knob 21 drives and connects the gear rotary switch 22. Specifically, a convex sleeve is formed at the lower end of the gear knob 21, and the convex sleeve is coaxially arranged with the body of the gear knob 21. The convex sleeve is coaxially adapted to be fitted outside the rotating shaft of the gear rotary switch 22, and the rotating shaft is a D-type shaft. Therefore, the actual output power of the fixed far-infrared heating tube 201, the left far-infrared heating tube 301 and the right far-infrared heating tube 401 can be adjusted by rotating the gear knob 21.
[0030] Furthermore, if Fig.11 As shown, a positioning frame strip 311 is formed at the lower end of the left handle 31. Fig.10 As shown, the upper end of the left swing heating assembly 3 is formed with an upper shaft head 35 and an upper protrusion 36. Fig. 9 As shown, the upper boss 36 is arranged through the upper cover plate 5, as shown in FIG. Fig.12 As shown, the upper cover plate 5 is formed with a rotation support hole 51. Fig. 9 As shown, the upper shaft head 35 is inserted upward into the corresponding rotation support hole 51, and an axial retaining ring 37 is installed on the upper end surface of the upper shaft head 35 to prevent the upper cover plate 5 from axially separating from the left swing heating component 3. The upper end of the upper boss 36 is arranged in the corresponding positioning frame strip 311. The upper boss 36 is connected to the bottom of the left handle 31 by a screw. Specifically, the above-mentioned screw passes through the bottom of the left handle 31 from top to bottom and is coaxially screwed with the upper boss 36, so that the left handle 31 and the shell assembly of the left swing heating component 3 are reliably fixed relative to each other. When the left handle 31 is rotated, the positioning frame strip 311 drives the upper boss 36 to swing, so as to prevent the above-mentioned screw from being easily loosened or causing damage to the screw connection structure. The connection structure between the right handle 41 and the shell assembly of the right swing heating component 4 is the same as the connection structure between the left handle 31 and the shell assembly of the left swing heating component 3.
[0031] Furthermore, if Figure 1 and Figure 2 As shown, the shapes of the left swing heating component 3 and the right swing heating component 4 are both set to be upright cylindrical shapes, so that the left swing heating component 3 and the right swing heating component 4 can be arranged closer to the fixed heating component 2, which is conducive to making the electric heater of the utility model compact. If the left swing heating component 3 is set to be a rectangular parallelepiped, when the left swing heating component 3 swings horizontally, the corner of the left swing heating component 3 will touch the fixed heating component 2.
[0032] Furthermore, if Figure 8 As shown, a lower convex column 33 is formed at the bottom of the left swing heating assembly 3. Figure 3As shown, the base 1 is formed with a base top 11, and a left limiting hole 113 for limiting the left swing heating component 3 to swing to the left is formed on the base top 11. The left limiting hole 113 is extended around the swing axis of the left swing heating component 3. In other words, the left limiting hole 113 is an arc-shaped long hole, and the lower protrusion 33 is arranged in the corresponding left limiting hole 113; specifically, as shown in FIG. Figure 3 As shown, a left-rotating mounting hole 111 is formed on the top 11 of the base. Figure 8 As shown, the bottom of the left swing heating assembly 3 is formed with a lower shaft head 32, as shown in FIG. Figure 7 As shown, the lower shaft head 32 is adapted to be inserted into the left rotating mounting hole 111, and then the lower axial retaining ring 34 is installed on the lower end surface of the lower shaft head 32 to prevent the base 1 from being axially separated from the left swing heating component 3. Therefore, the left swing heating component 3 specifically swings around the axis of the lower shaft head 32, as shown in FIG. Figure 3 As shown, the left limit hole 113 is arranged on the outside of the left rotating mounting hole 111, so when the left swinging heating component 3 swings horizontally to a certain amplitude, the lower boss 33 contacts the end of the left limit hole 113, and the left limit hole 113 will block the left swinging heating component 3. As mentioned above, the left limit hole 113 is used to limit the left swinging heating component 3 to swing to the left. In other words, the left swinging heating component 3 is limited to swinging from the front position to the left position; further, in order to prevent the far-infrared electric heater from irradiating and heating in an excessively dispersed range, resulting in a large range of heating void areas, the left limit hole 113 is set to limit the left swinging heating component 3 to swing 45° to the left from the front position. Similarly, as Figure 3 As shown, a right limiting hole 114 for limiting the right swinging heating component 4 to swing rightward is formed on the top 11 of the base, and the right swinging heating component 4 is rotatably connected to the right rotating mounting hole 112 .
