[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] To achieve the above objectives, the technical solution of this utility model is as follows:

[0031] See Figure 1-8 As shown, this embodiment provides a heater with a rotatable plug, including: a heater body 1, a plug 2, and a plug fixing member 3. The plug 2 includes a main body 21 and a rotating part 22. The heater body 1 has a mounting part 11, which is clamped between the main body 21 and the plug fixing member 3. A rotating hole 12 is provided on the mounting part 11, and the rotating part 22 is rotatably installed in the rotating hole 12. The plug fixing member 3 and the rotating part 22 are fixedly connected by screws.

[0032] In this embodiment, the design of the above structure allows the plug 2 to rotate relative to the main body 1 of the heater, thereby facilitating the adjustment of the insertion direction of the plug 2. This makes it more convenient to use in scenarios with narrow spaces or unreasonable socket layouts. At the same time, it can also avoid excessive bending of the power cord caused by forcibly inserting the plug 2, reducing safety hazards when using the socket, and making it easier for users to place the device according to the socket direction, making it more convenient to use.

[0033] Furthermore, a first rotation limiting protrusion 23 is provided on the side wall of the rotating part 22, and a rotating slide 13 is provided on the side wall of the rotating hole 12. A second rotation limiting protrusion 14 is provided on the rotating slide 13. The first rotation limiting protrusion 23 is movably disposed on the rotating slide 13, and the second rotation limiting protrusion 14 is located on the rotation circumference of the first rotation limiting protrusion 23. In this embodiment, the second rotation limiting protrusion 14 can limit the rotation of the first rotation limiting protrusion 23, so that the rotating part 22 can only rotate within a 180-degree angle range, avoiding the rotating part 22 from rotating too much and thus breaking the electrical connection between the plug 2 and the heater body 1.

[0034] Furthermore, a positioning hole 24 is provided on the side of the rotating part 22 near the plug fixing member 3, and a positioning protrusion 31 is provided on the plug fixing member 3, which is inserted into the positioning hole 24. When the plug 2 is installed, it can be positioned by the positioning structure formed by the positioning protrusion 31 and the positioning hole 24, thereby improving the stability of the plug 2 installation.

[0035] Furthermore, the main body 1 of the heater also includes a control board 4, which is located on the side of the plug fixing member 3 away from the rotating part 22. A power terminal 25 is installed on the side of the main body 21 away from the rotating part 22. A first wire hole 32 is provided on the plug fixing member 3, and a second wire hole 26 is provided on the rotating part 22. The first wire hole 32 and the second wire hole 26 are connected to realize the wiring between the control board 4 and the power terminal 25. This structural design facilitates the wiring between the control board 4 and the plug 2.

[0036] Furthermore, the main body 1 of the heater also includes a housing 15, with the mounting part 11 opened on the housing 15, and the control main board 4 and the plug fixing part 3 disposed inside the housing 15.

[0037] Furthermore, the housing 15 is also provided with a heating element 5 and a heating element fixing shell 6.

A fixing position is formed between the support boss 61 and the first buckle 62, and the heating element 5 is set on the fixing position.

[0038] Furthermore, the main body 1 of the heater also includes a clamping shell 16 and an upper cover 17. The upper cover 17 is fastened to the housing 15. The clamping shell 16 is located above the heating element fixing shell 6 and is installed on the upper cover 17. The clamping shell 16 is provided with two opposing second buckles 161, which are respectively fastened to the outer side walls on opposite sides of the heating element fixing shell 6.

[0039] In this embodiment, when the clamping shell 16 is installed, the second buckle 161 can clamp the heating element fixing shell 6. The wall of the heating element fixing shell 6 is squeezed inward after being subjected to force, so that the first buckle 62 can tightly hold the heating element 5, thereby improving the structural stability of the heating element 5.

[0040] Furthermore, a fan 7 is provided below the heating element 5, and an air inlet 18 is provided on the housing 15. The air inlet 18 is located below the fan 7. A vent 162 is also provided on the clamping housing 16. An air outlet 8 is covered on the vent 162. The air outlet 8 is clamped and fixed between the upper cover 17 and the clamping housing 16.

[0041] Furthermore, the main body 1 of the heater also includes a display module 9, which includes a display circuit board 91, a display screen 92, and a lens 93. The display circuit board 91 is installed inside the housing 15 and connected to the control main board 4; the display screen 92 is installed on the display circuit board 91, and the lens 93 is located above the display screen 92 and installed on the top cover 17.

[0042] Furthermore, the outer wall of the housing 15 is also provided with a support foot 19, which can provide support when the plug 2 is inserted, thereby ensuring the stability of the plug 2 insertion.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
