DETAILED DESCRIPTION

[0025] In order to better understand the purpose, structure and function of the present invention, the following Figure 1-8 , an adjustable air outlet device and an electric heater of the present invention are further described in detail.

[0026] The existing electric film heaters have a single heating mode, a fixed temperature radiation range and direction, and the heating effect for users is not perfect. The present invention provides an adjustable air outlet device, which is mainly used on electric heaters and is arranged in the electric heater housing 1. It uses a remote control mechanism with radiation-enhanced convection and controllable wind direction. The remote control mechanism can adjust the direction of the air outlet 4 when the remote control lever is rotated to increase the convection effect, and can also change the air supply distance and adjust the temperature radiation range, so that users can use the electric heater for heating in a larger range.

[0027] like Figures 1 to 3 As shown, the present invention provides an adjustable air outlet device, including an adjusting structure 7, which is arranged at the air outlets 4 on both sides of the shell, and a first volute tongue 71 and a second volute tongue 72 are arranged above the air outlets 4 on both sides. The adjusting structure 7 moves and overlaps with the first volute tongue 71 and the second volute tongue 72 respectively, so as to adjust the air outlet 4.

[0028] like Figure 5 As shown, the bottom edges of the first volute tongue 71 and the second volute tongue 72 are provided with grooves 711 , and when the adjustment structure 7 moves and overlaps with the grooves 711 , the air outlet 4 is changed.

[0029] An adjustment structure 7 is provided between the first volute tongue 71 and the second volute tongue 72 , and the first volute tongue 71 and the second volute tongue 72 are symmetrically provided on both sides of the adjustment structure 7 . When the adjustment structure 7 adjusts the air outlet 4 , the rotation angles of the two sides and the first volute tongue 71 or the second volute tongue 72 are the same.

[0030] like Figures 6 to 8 As shown, the adjustment structure 7 includes a connecting shaft 73, which is fixed on the side plate of the shell 1. The connecting shaft 73 and the side plate of the shell 1 are vertically connected. A through groove 733 is provided on the outer periphery of the connecting shaft 73, and a screw hole 731 is provided on one side of the through groove 733. A motor hole 732 is provided at the end of the connecting shaft 73, and the motor hole 732 is fixedly connected to the second motor 3.

[0031] The through slot 733 is fixedly connected with a rocker assembly 74 , and the rocker assembly 74 swings left and right to overlap with the first volute tongue 71 and the second volute tongue 72 , thereby changing the air outlet direction of the air outlet 4 .

[0032] The rocker assembly 74 includes a baffle 741 disposed vertically in the through slot 733 , a bottom plate 742 is fixedly connected to the bottom of the baffle 741 , and retaining ribs 743 are fixedly connected to both sides of the baffle 741 to enhance the firmness of the rocker assembly 74 .

[0033] Furthermore, a connection hole 744 is provided on the edge of the baffle 741 for fixedly connecting the baffle 741 and the connecting shaft 73 .

[0034] Furthermore, the bottom plate 742 is an arc-shaped plate structure, and protrusions are provided at both ends of the bottom plate 742. The connecting shaft 73 rotates, driving the rocker assembly 74 to swing, and the bottom plate 742 swings left and right, so that the protrusion of the bottom plate 742 and the groove 711 of the first volute tongue 71 and the second volute tongue 72 cooperate with each other. When the bottom plate 742 and the first volute tongue 71 overlap, the left air outlet 4 is closed. When the bottom plate 742 and the second volute tongue 72 overlap, the right air outlet 4 is closed. When the bottom plate 742 is placed in a static position, air is discharged from the air outlets 4 on both sides, thereby realizing the adjustment of the air outlet 4 and the adjustment of the air volume on both sides.

[0035] like Figure 4 As shown, a base 75 is provided below the bottom plate 742, and the bottom plate 742 and the base 75 are slidably matched, so that after the bottom plate 742 is rotated, it is sealed with the base 75 without any gap, so that the one-way air supply volume reaches the maximum.

[0036] A slide groove 751 is provided on the upper surface of the base 75 . The shape of the slide groove 751 matches the arc surface of the bottom plate 742 . The bottom plate 742 swings left and right and slides in a sealed manner with the slide groove 751 of the base 75 .

[0037] Furthermore, a fixing hole 752 is provided on the base 75 for fixing the base 75 and the housing 1 .

[0038] The present invention also provides an electric heater, including a shell 1, the bottom of the shell 1 is provided with the above-mentioned adjustable air outlet structure, a wind wheel 6 is provided above the adjustable air outlet structure, a heating element 5 is provided above the wind wheel 6, and a first motor 2 is fixedly connected to one side of the wind wheel 6.

[0039] When the rocker assembly 74 is stationary, the wind wheel 6 removes the heat from top to bottom and then from the air outlets 4 at both ends. At this time, both ends of the electric heater can be heated, and the heating range is wide, which is suitable for heating multiple people; when the rocker assembly 74 swings to the left (right), the air outlet 4 on one side is closed, and the air volume is only discharged from the other side for heat dissipation, and the air is discharged on one side. At this time, the air supply distance is enhanced, and the personal heating effect is optimal; the rocker assembly 74 is driven by the second motor 3 to rotate the connecting shaft 73, and the second motor 3 can be set to 2 gears for regulation, namely, stationary, left turn and right turn 30 degrees. It has a simple structure and is easy to operate.

[0040] When the user is using it, he can adjust the stepper motor switch under fixed power. According to his own needs, he can adjust the motor gear, control the joystick, adjust the air outlet direction, change the convection direction and distance, and choose more ways to give users a better heating experience.

[0041] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
