[0034] The following is for reference. Figures 1-4 This invention describes an electric heater according to an embodiment of the present invention.

[0035] like Figures 1-4 As shown, the electric heater includes a control base 100, a swing frame 200, and a heating and air supply assembly 300. The control base 100 is equipped with a control panel 110 and a horizontal swing assembly 120. The control panel 110 is electrically connected to the horizontal swing assembly 120. The user can adjust the working status of the heater through the control panel 110. The horizontal swing assembly 120 is fixed inside the control base 100 and connected to the swing frame 200 to drive the swing frame 200 to rotate.

[0036] The swing frame 200 has a ring-shaped structure and its bottom is connected to the horizontal swing assembly 120 via a transmission connection. A display assembly 210 is provided on the side of the swing frame 200 near the control base 100. The display assembly 210 is used to display the current working status. The working status adjusted by the control panel 110 can be displayed on the display assembly 210, which can show whether the device is in power-saving mode and the current working temperature.

[0037] The heating and air supply assembly 300 is embedded within the swing frame 200. One end of the heating and air supply assembly 300 is rotatably connected to the swing frame 200, and the other end is slidably connected to the swing frame 200. A person presence sensor 360 is disposed on the surface of the heating and air supply assembly 300. Both the person presence sensor 360 and the heating and air supply assembly 300 are electrically connected to the control panel 110. Specifically, the housing of the heating and air supply assembly 300 has a racetrack-shaped structure and is installed within the annular region of the swing frame 200. The housing of the heating and air supply assembly 300 is connected to the inner wall of the swing frame 200, thereby fixing the heating and air supply assembly 300 within the swing frame 200.

[0038] The Human Sensor 360 utilizes infrared and radar technology to detect human presence. Specifically, the infrared sensor detects changes in spatial thermal radiation caused by human movement, while millimeter-wave radar senses the undulations or subtle movements of the human body. The Human Sensor 360 can accurately detect the presence of a user within its detection area, sending a signal to the control panel 110. The heating and air supply assembly 300 then enters high-efficiency mode, maintaining high power and air supply efficiency for a specified time. Repeated detection of a human by the Human Sensor 360 during this period will not affect the current operating mode. After a specified period of efficient operation, the heater load stops. After the heater has cooled down for a specified time, when the Human Sensor 360 detects a human again, the heater re-enters high-efficiency mode.

[0039] In some embodiments of this utility model, such as Figures 1-3 As shown, the heating and air supply assembly 300 is provided with a heating element 320 and a fan assembly 330. The fan assembly 330 is located on the back of the heating element 320, and an air outlet net 310 is provided in front of the heating element 320. The fan assembly 330 blows air into the heating element 320, which is heated by the heating element 320 and then sent out from the air outlet net 310.

[0040] Specifically, the heating and air supply assembly 300 is arranged with an air outlet mesh 310, a heating element 320, and a fan assembly 330 sequentially from the air supply surface to the air inlet surface. Air is drawn into the housing by the fan assembly 330 and comes into contact with the heating element 320 to achieve air heating before being delivered out through the air outlet mesh 310. The air outlet mesh 310 adopts a metal mesh structure to prevent foreign objects or flammable materials from directly contacting the heating element 320, and also to prevent accidental contact by the user. The heating element 320 is a PTC heating element, which generates heat after being energized. As the temperature rises, its resistance increases, limiting further increases in current and achieving automatic temperature control.

[0041] Furthermore, such as Figure 3 As shown, a filter 340 (the mesh size of the filter 340 is not shown in the attached diagram, it is for reference only) and an air inlet cover 350 are provided on one side of the fan assembly 330. The air inlet cover 350 is detachably connected to the housing of the heating and air supply assembly 300. Specifically, the filter 340 can prevent dust, flammable foreign objects, etc. from the outside air from entering the heating element 320, thus achieving a filtering effect. The air inlet cover 350 is detachable, allowing the filter 340 to be removed for cleaning.

[0042] Furthermore, such as Figures 1-4 As shown, the human body sensor 360 is located in the lower half of the housing of the heating and air supply assembly 300, embedded in the surface of the air outlet mesh 310. The height at which the human body sensor 360 is positioned can cover a large area, improving the accuracy of the detection range.

[0043] In some embodiments of this utility model, such as Figures 1-4 As shown, the lower half of the housing of the heating and air supply assembly 300 is provided with a rotating seat 301, which is rotatably connected to the swing frame 200. The upper half of the housing of the heating and air supply assembly 300 is provided with a swing groove 302, and the swing frame 200 is provided with a swing seat 220, which is slidably connected within the swing groove 302. Specifically, the heating and air supply assembly 300 swings longitudinally around the rotating seat 301 as an axis of rotation, thereby changing the air supply height. The slidable connection between the swing groove 302 and the swing seat 220 determines the longitudinal swing angle of the heating and air supply assembly 300.

[0044] Furthermore, a rubber ring is fitted around the periphery of the swing seat 220, and the periphery of the rubber ring contacts the inner wall of the swing groove 302 to increase the swing damping.

[0045] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the horizontal swing assembly 120 includes a rotating base 122 and a drive motor 121. The drive motor 121 and the rotating base 122 are connected by a connecting rod, and the middle part of the rotating base 122 is fixedly connected to the bottom of the swing frame 200. Specifically, the drive motor 121 is a stepper motor, which can precisely control the horizontal rotation angle of the rotating base 122.

[0046] Furthermore, such as Figure 1 and Figure 2 As shown, the control panel 110 is located on the inclined side wall of the control base 100.

[0047] Furthermore, such as Figure 1 and Figure 2 As shown, there are gaps between the inner wall of the swing frame 200 and the top and bottom ends of the heating and air supply assembly 300. Specifically, the gaps between the swing frame 200 and the heating and air supply assembly 300 allow the top of the swing frame 200 to be used as a handle.

[0048] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0049] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
