[0042] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. 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.

[0043] 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.

[0044] 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.

[0045] Figures 1 to 6 A heater provided in an embodiment of the present application includes a shell frame 1, a first heating element 2 and a second heating element 3. The shell frame 1 has a mesh side wall (not shown in the figure) on its circumferential side, and the mesh side wall is provided with mesh holes; the first heating element 2 is connected to the shell frame 1; the first heating element 2 extends in the up-down direction; the second heating element 3 is connected to the shell frame 1 and extends in the up-down direction; the second heating element 3 is spaced apart and arranged in parallel with the first heating element 2 in the left-right direction; wherein, the second heating element 3 changes color after heating during operation. In this way, the shell frame 1 provides an installation base for the first heating element 2 and the second heating element 3, and the first heating element 2 and the second heating element 3 are arranged at the same time, which can improve the heating efficiency. In the present application, the shell frame 1 has a mesh side wall on its circumferential side. When the second heating element 3 heats up, the second heating element 3 changes color, and the light and shadow effect after the color change can be displayed through the mesh holes of the mesh side wall, which will produce a warm visual effect for the user, and also provide a beautified appearance.

[0046] refer to Figure 1The shell frame 1 is also provided with a first handle 15, a second handle 16 and an operating panel 17. The first handle 15 is provided on the upper side of the shell frame 1, the second handle 16 is provided on the right side of the shell frame 1, and the operating panel 17 is provided on the left side of the shell frame 1. An upper heating port 10 is provided on the upper side of the shell frame 1, and a lower air inlet is provided on the lower side. Air can enter from the lower air inlet, then take away heat after passing through the first heating element 2 and the second heating element 3, and be discharged from the upper heating port 10. This is natural convection heating formed by the principle of air flow. It can be understood that the first handle 15 can be used to facilitate the lifting of the heater. When the heater is working, due to the high temperature at the upper heating port 10, it is inconvenient to drive the heater by pulling the first handle 15. The heater can be driven to move by pulling the second handle 16 provided on the side panel.

[0047] In this embodiment, the grid side wall is provided on the front side and / or the rear side of the shell frame 1, and the grid side wall is provided with grid holes. The heat radiated by the first heating element 2 and the second heating element 3 can not only be discharged through the upper heating port 10, but also radiated through the grid holes of the grid side wall, thereby improving the heating radiation range of the heater.

[0048] In this embodiment, a housing is provided around the outer periphery of the housing frame 1, and a second handle 16 and an operating panel 17 are disposed on the housing. The mesh sidewalls can be attached to the housing frame 1 or disposed within the housing. The mesh sidewalls are exposed to ensure that heat from the first and second heating elements 2, 3 can be radiated to the outside, and the user can see the color display effect generated by the heat from the second heating element 3 through the mesh holes.

[0049] The bottom of the housing frame 1 is also provided with a support foot 18, and the support foot 18 is provided with a roller 181, which can facilitate the free movement of the placement position of the heater, making it convenient to use and carry.

[0050] In the technical solution of this embodiment, the second heating element 3 is a black tube heating element, which appears red when heating; the first heating element 2 is a mica electric heating film heating element.

[0051] It is understandable that this application adds a black tube heater to the traditional mica electrothermal film heater. The black tube heater can quickly heat up to the set temperature after power is applied, improving the heating efficiency of the product. Moreover, the black tube heater turns red when heated, which creates a warm visual effect for users when using the product. The addition of the black tube heater to the mica electrothermal film heater can enhance the personalization of the entire product.

[0052] The number of the first heating element 2 is at least one. Figures 1 to 6As shown, in the technical solution of this embodiment, there are two first heating elements 2 and one second heating element 3. The two first heating elements 2 are arranged in parallel and spaced apart, and the second heating element 3 is located between the two first heating elements 2. It should be noted that in other embodiments, when there are three or more first heating elements 2, the second heating element 3 can be arranged between any two first heating elements 2. In other embodiments, there can also be multiple second heating elements 3.

[0053] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, in the technical solution of this embodiment, the first heating element 2 is set at an angle to the upper bracket 11, so that the plane where the first heating element 2 is located is set at an angle to the connecting surface of the left bracket 13 and the right bracket 14.

[0054] The first heating element 2 is set to be at an angle to the upper bracket 11, and also to be at an angle to the lower bracket 12, that is, the projection of the first heating element 2 in the vertical direction intersects with the lower bracket 12 and forms an angle. In this way, the lower bracket 12 and the upper bracket 11 reduce the obstruction of the air passing through the surface of the first heating element 2, which can effectively improve the upper and lower heat convection circulation of the heater in terms of spatial structure, reduce the overall surface temperature of the electric heater, and improve the safety performance of the product. Specifically, if the vertical projection of the first heating element 2 is entirely on the lower bracket 12, then the air entering from the lower air inlet must bypass the lower bracket 12 before it can flow to the surface of the first heating element 2. However, with the structural design of the present application, most of the air entering from the lower air inlet flows directly to the surface of the first heating element 2, which can effectively improve the upper and lower heat convection circulation of the heater, reduce the overall surface temperature of the electric heater, and improve the safety performance of the product.

[0055] like Figures 1 to 6 As shown, in the technical solution of this embodiment, the housing frame 1 includes an upper bracket 11 and a lower bracket 12 arranged vertically, and a left bracket 13 and a right bracket 14 arranged horizontally. The two ends of the upper bracket 11 are respectively connected to the left bracket 13 and the right bracket 14, and the two ends of the lower bracket 12 are respectively connected to the left bracket 13 and the right bracket 14.

[0056] The upper and lower ends of the first heating element 2 are respectively connected to the upper bracket 11 and the lower bracket 12, and are located between the left bracket 13 and the right bracket 14;

[0057] The upper and lower ends of the second heating element 3 are respectively connected to the upper bracket 11 and the lower bracket 12 , and are located between the left bracket 13 and the right bracket 14 .

[0058] It can be understood that the upper bracket 11 , the lower bracket 12 , the left bracket 13 and the right bracket 14 are connected to form a frame structure, which provides an installation position and support for the first heating element 2 and the second heating element 3 .

[0059] like Figures 1 to 6 As shown, in the technical solution of this embodiment, the first heating element 2 is connected to the upper bracket 11 and the lower bracket 12 through the first connecting component 4 respectively.

[0060] It can be understood that the first connecting assembly 4 can realize a detachable connection between the first heating element 2 and the upper bracket 11 and the lower bracket 12 to facilitate assembly and disassembly.

[0061] like Figure 3 、 Figure 5 and Figure 6 As shown, in the technical solution of this embodiment, the first connecting component 4 includes a connecting seat 41 and a first ceramic head 42, the connecting seat 41 includes a first connecting portion 411 and a second connecting portion 412 connected at an angle, the first connecting portion 411 is positioned and clamped on the upper bracket 11 or the lower bracket 12, and is connected to the upper bracket 11 or the lower bracket 12 through a first bolt; the second connecting portion 412 is parallel to the first heating element 2, and the second connecting portion 412 is connected to the first heating element 2 through a second bolt; the first ceramic head 42 is clamped between the second connecting portion 412 and the first heating element 2, and the second bolt is passed through the first ceramic head 42.

[0062] It can be understood that the first heating element is assembled on the shell frame 1 by means of bolts; at the same time, the first ceramic head 42 is made of ceramic material. Since ceramic material has good electrical insulation performance and high temperature resistance, the introduction of the first ceramic head 42 can improve the connection stability between the connecting seat 41 and the shell frame 1, and the first ceramic head 42 can prevent the first connecting component 4 and the first heating element from being energized, that is, prevent the first heating element from being energized with the shell frame 1, thereby ensuring the safe use of this heater.

[0063] like Figures 1 to 6 As shown, in the technical solution of this embodiment, the second heating element 3 is connected to the upper bracket 11 and the lower bracket 12 through a second connecting component 5 .

[0064] It can be understood that the second connecting assembly 5 can realize a detachable connection between the second heating element 3 and the upper bracket 11 and the lower bracket 12 to facilitate assembly and disassembly.

[0065] like Figure 3 and Figure 5As shown, in the technical solution of this embodiment, the second connecting component 5 includes a second ceramic head 51 and a washer 52. The second ceramic heads 51 are respectively mounted on both ends of the second heating element 3 and are connected to the upper bracket 11 and the lower bracket 12 respectively through the second ceramic heads 51; the washer 52 is mounted on the second ceramic head 51 and is clamped between the second ceramic head 51 and the upper bracket 11 or the lower bracket 12. The second ceramic head 51 has two spaced-apart convex rings, between which the upper bracket 11 or the lower bracket 12 is mounted, that is, the two convex rings are respectively located on the upper and lower sides of the upper bracket 11 or the lower bracket 12. The washer 52 plays a role in buffering and improving the stability of the connection.

[0066] In this embodiment, to facilitate assembly, the outer diameter of one convex ring is smaller than the outer diameter of the other convex ring, and the gasket 52 is located between the smaller convex ring and the upper bracket 11 (or lower bracket 12), which can prevent the second ceramic head 51 from detaching from the upper bracket 11 (or lower bracket 12).

[0067] Furthermore, the second ceramic head 51 is made of ceramic material. The introduction of the second ceramic head 51 can improve the connection stability between the second heating element and the shell frame 1, and the second ceramic head 51 can prevent electricity from being passed between the shell frame 1 and the second heating element, thereby ensuring the safety of the heater.

[0068] like Figure 5 As shown, in the technical solution of this embodiment, it also includes a fixing ring 6, which is sleeved on the lower end of the second heating element 3, and the fixing ring 6 is located below the second ceramic head 51. The circumferential side of the fixing ring 6 is provided with threaded holes, and the fixing ring 6 is fastened to the second heating element 3 by a third bolt (not numbered in the figure).

[0069] It can be understood that, by providing the fixing ring 6 , the second ceramic head 51 can be limited, thereby preventing the second ceramic head 51 from axially moving relative to the second heating element.
