Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0059] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0060] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0061] Figure 1 A heater is provided in an embodiment of the present application, which includes a base 1, a left-right swing mechanism 2 and an up-down swing mechanism 3; the left-right swing mechanism 2 is rotatably connected to the base 1 so that the left-right swing mechanism 2 rotates around the axis of the base 1; the up-down swing mechanism 3 is connected to the left-right swing mechanism 2 so that the up-down swing mechanism 3 rotates around the direction perpendicular to the axis of the base 1; a heater body 4, and the heater body 4 is connected to the up-down swing mechanism 3.

[0062] It is understood that the base 1 provides a stable foundation, the vertical swing mechanism 3 drives the heater body 4 to swing up and down, and the left and right swing mechanism 2 drives the vertical swing mechanism 3 to swing left and right, thereby driving the heater body 4 to swing left and right. By providing the vertical swing mechanism 3 and the left and right swing mechanism 2, the present application can achieve that the heater body 4 can swing up and down while swinging left and right, thereby increasing the radiation range of the heater, expanding the warming area, and achieving all-round heating.

[0063] like Figure 2 、 Figure 3 and Figure 4As shown, in the technical solution of this embodiment, the left and right swing mechanism 2 includes a first shell 21, a first support frame 22, a first drive motor 23 and a first toothed member 25, the first shell 21 has a first accommodating chamber 21a; the first shell 21 is rotatably connected to the base 1; the first shell 21 is connected to the up and down swing mechanism 3; the first support frame 22 is arranged in the first accommodating chamber 21a; and the first support frame 22 is connected to the first shell 21; the first drive motor 23 is arranged in the first accommodating chamber 21a; the first drive motor 23 is arranged in the first support frame 22, and the output end of the first drive motor 23 is provided with a first driving gear 24; the first toothed member 25 is arranged in the first accommodating chamber 21a; the first toothed member 25 is connected to the base 1, and the first toothed member 25 is rotatably connected to the first support frame 22; the outer periphery of the first toothed member 25 is provided with a first tooth portion 251; the first driving gear 24 is meshed with the first tooth portion 251.

[0064] It can be understood that the first driving motor 23 drives the first driving gear 24 to rotate, and the first driving gear 24 is engaged with the first tooth portion 251. Since the first toothed member 25 is fixedly connected to the base 1, when the first driving gear 24 generates a force on the first tooth portion 251, the first driving gear 24 moves under the reaction of the first tooth portion 251, and the movement of the first driving gear 24 drives the first support frame 22 to rotate, and the first support frame 22 drives the first shell 21 to rotate. When the first shell 21 rotates, it drives the up and down swinging mechanism 3 to rotate, and then drives the heater body 4 to rotate, thereby realizing the left and right swing of the heater body 4.

[0065] like Figure 3 and Figure 4 As shown, in the technical solution of this embodiment, the base 1 is provided with a first assembly hole 1a; the first toothed member 25 is provided with a first assembly shaft 252, the first assembly shaft 252 is passed through the first assembly hole 1a, and the first tooth portion 251 is connected to the base 1 through a fastener.

This embodiment has a simple structure and high stability.

[0069] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, in the technical solution of this embodiment, the up and down swing mechanism 3 includes a second shell 31, a second support frame 32, a second drive motor 33, a second toothed member 35 and a second connecting frame 36.

The second shell 31 is provided with an avoidance hole 31b. The second support frame 32 is provided in the second accommodating cavity 31a. The second support frame 32 is provided with a first connecting frame 321. The first connecting frame 321 is movable. A movable thread is provided in the avoidance hole 31b.

[0070] It can be understood that the second drive motor 33 drives the second driving gear 34 to rotate. When the second driving gear 34 rotates, it drives the second toothed part 35 to rotate through the second tooth portion 351. When the second toothed part 35 rotates, it drives the second connecting frame 36 to rotate, and then drives the heater body 4 to swing up and down. The up and down swinging of the heater body 4 drives the second shell 31 to swing up and down, and the second shell 31 rotates relative to the second support frame 32. Since the avoidance hole 31b is provided in the second shell 31, the relative rotation of the second shell 31 and the second support frame 32 can be realized, that is, the avoidance hole 31b is provided to prevent mistakes.

[0071] like Figure 6 and Figure 7As shown, in the technical solution of this embodiment, the second connecting frame 36 includes a connecting shaft 361, a torsion spring 362, a first transmission member 363, a second transmission member 364, and a docking member 365.

[0072] It is understood that when the second toothed member 35 rotates driven by the second driving gear 34, it drives the first transmission member 363 to rotate, the first transmission member 363 drives the connecting shaft 361 to rotate, and the rotation of the connecting shaft 361 drives the second transmission member 364 to rotate. The docking member 365 swings up and down driven by the first and second transmission members 363 and 364, thereby driving the heater body 4 to swing up and down. The torsion spring 362 is provided to provide a buffer for the up and down swinging.

[0073] like Figure 6 and Figure 7 As shown, in the technical solution of this embodiment, the second support frame 32 includes a third shell 322 and a fixing frame 323. The third shell 322 is arranged in the second accommodating chamber 31a, and the bottom of the outer wall of the third shell 322 is connected to the first connecting frame 321; the third shell 322 has a third accommodating chamber, and the two opposite side walls of the third shell 322 are provided with through holes; the docking member 365 is located on the outside of the third shell 322; the second toothed member 35, the second drive motor 33, the connecting shaft 361, and the torsion spring 362 are located in the third accommodating chamber; the first transmission member 363 is movably provided in one through hole, and the second transmission member 364 is movably provided in another through hole; the fixing frame 323 is arranged in the third accommodating chamber and is connected to the third shell 322; the connecting shaft 361 is rotatably connected to the fixing frame 323; the second drive motor 33 is connected to the fixing frame 323.

[0074] It is understood that the second support frame 32 plays an isolating and protective role for the components disposed in the second accommodating cavity 31a, and the fixing frame 323 provides a mounting support base. The provision of the through hole can achieve the purpose of transmitting power from the second accommodating cavity 31a to the docking member 365.

[0075] like Figure 1 and Figure 9 As shown, in the technical solution of this embodiment, the heater body 4 includes a fourth shell 41, a grille cover 42, a heating element 43, and a reflective cover 44.
