Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a heating element of the present application. The heating assembly 100 includes a heating body 10 and a heating side post 20.

In some embodiments, the heating side pillar 20 includes a side pillar body 201 and a decoration 202, the side pillar body 201 is disposed on an outer wall of the heating body 10, and the decoration 202 is sleeved on the side pillar body 201. The side pillar body 201 and the heating body 10 may be integrally formed or may be provided in two parts, which is not limited in this application and can be selected by those skilled in the art according to actual needs.

Referring to fig. 1 and 9 together, fig. 9 is a schematic structural diagram of a knob assembly of the heating assembly shown in fig. 1. The heating assembly 100 also includes a knob assembly 40, and the knob assembly 40 may be disposed on the heating jamb 20. Specifically, the side pillar body 201 has an accommodating cavity (not labeled in the drawings), a first opening 201b communicated with the accommodating cavity is further formed on a first side wall 201a of the side pillar body 201, and a second opening 202b corresponding to the first opening 201b is formed on a second side wall 202a of the decoration 202. In some embodiments, the first opening 201b and the second opening 202b may be concentric circular holes.

The knob assembly 40 includes a circuit board 41 and a knob body 42 disposed on the circuit board 41, the circuit board 41 can be disposed in the accommodating cavity, one end of the knob body 42 is disposed in the accommodating cavity and connected to the circuit board 41, and the other end of the knob body extends out of the first opening 201b and the second opening 202b in sequence for user operation.

In some embodiments, the heating side pillar 20 may not include the decoration 202, and only includes the side pillar body 201, which is not limited in this application and can be selected by those skilled in the art according to actual needs.

The decorative member 202 is provided to improve the appearance of the heating element 100. In one aspect, the provision of the decorative member 202 enables the heating body 10 and the heating side pillar 20 to have different colors. When the whole columns of the heating body 10 and the heating side column 20 are integrally formed, the two-color injection molding of the whole columns of the heating body 10 and the heating side column 20 is difficult to realize due to the limitation of the prior art process.

The inventor has found that the technical scheme of arranging the heating body 10 and the side pillar body 201 in two without arranging the decoration 202 can also enable the heating body 10 and the side pillar body 201 to have different color matching. However, the two-piece arrangement of the heating body 10 and the side column body 201 is poor in product reliability, and faces the problems of water resistance, safety creepage distance, structural strength and the like. Particularly, in the case of the waterproof problem, no matter how the assembly manner of the heating body 10 and the side pillar body 201 is set, there is a problem that moisture enters the inside of the product along the assembly gap between the two, resulting in the functional damage or failure of the product.

Compare in not setting up decoration 202, will heat the technical scheme that body 10 and side post body 201 two-piece set up, this application heats body 10 and side post body 201 integrated into one piece, and the scheme that side post body 201 was located to decoration 202 cover can improve the outward appearance effect of product, can guarantee the reliability of product again.

On the other hand, even if the heating body 10 and the heating side pillar 20 have the same color, the provision of the garnish 202 is advantageous in improving the appearance of the heating assembly 100. In fact, the side post body 201 has a complex structure, and has many through holes and ribs, and is limited by the existing injection molding process, so that many mold defects which are difficult to eliminate, such as flow marks, sliding block marks, welding marks and the like, are present, and the side post body is unacceptable as an appearance. For example, when the heating body 10 and the side pillar body 201 have the same color matching and are both flash powder surfaces, the side pillar body 201 is very easy to generate flow marks due to sudden change of injection pressure due to too complicated structure, and the appearance of the product is affected. The decoration 202 can shield the appearance defects of the side column body 201, so that the appearance of the heating assembly 100 is improved.

The heating assembly 100 may be a heating magnet. The heating body 10 may be provided in a circular shape, and the side pillar body 201 extends outward from the outer wall of the heating body 10. In some embodiments, the heating body 10 may also be disposed in a square shape, which is not limited in this application and can be selected by those skilled in the art according to actual needs.

As for the specific structure of the heating body 10, as shown in fig. 2, fig. 2 is an exploded structural view of the heating assembly shown in fig. 1. The heating body 10 includes a housing 101, a panel 102, and a heating source 103. The side column body 201 is integrally formed with the housing 101. The panel 102 covers the housing 101, and forms an accommodating space together with the housing 101 for accommodating the heating source 103. For example, the heating source 103 may be a coil, which is not limited in this application and can be selected by one skilled in the art according to actual requirements.

The housing 101 may include a center 1011 and a base 1012, as shown in fig. 2, the center 1011 and the base 1012 may be a two-piece arrangement. The base 1012 and the panel 102 are disposed on two sides of the middle frame 1011, respectively.

Correspondingly, the side post body 201 may include a first side post body 2011 and a second side post body 2012, as shown in fig. 2, and the first side post body 2011 and the second side post body 2012 may be provided in two pieces. Specifically, the first side post body 2011 may be integrally formed with the center frame 1011, and the second side post body 2012 may be integrally formed with the base 1012.

In some embodiments, the center 1011 and the base 1012 may be integrally formed. Correspondingly, the first side post body 2011 and the second side post body 2012 can be integrally formed. The present application is not limited thereto, and those skilled in the art can select the above according to actual needs.

Referring to fig. 2 and 3, fig. 3 is a schematic structural diagram of a control circuit board of the heating element shown in fig. 2. The heating assembly 100 further includes a control circuit board 30 disposed in the cavity of the side pillar body 201 and extending out of the side pillar body 201 to control the heating source 103. The circuit board 41 and the control circuit board 30 can be electrically connected.

Referring to fig. 4, fig. 4 is a schematic structural view of a decoration of the heating element shown in fig. 2. Optionally, a waterproof structure is provided at the abutting position of the decoration 202 and the housing 101 to prevent moisture from entering the portion of the control circuit board 30 extending out of the side pillar body 201 along the assembly gap between the decoration 202 and the housing 101, thereby improving the reliability of the heating assembly 100.

Referring to fig. 2 and 4, the decoration 202 may include a top wall 2022 adjacent to the panel 102 and parallel to the panel 102. A groove 20221 is formed in one side of the top wall 2022 adjacent to the middle frame 1011, a sealing strip 20222 is arranged in the groove 20221 to serve as a waterproof structure, and the sealing strip 20222 is compressed and deformed under the pressing action of the panel 102, so that sealing and waterproofing are achieved.

In the description of the present application, two objects are parallel to each other, and may be allowed to have a certain error range, for example, an error range of-5 ° to 5 °, that is, an angle between the two is in a range of-5 ° to 5 °, and the two can be considered to be parallel to each other. For example, the top wall 2022 and the panel 102 are parallel to each other, and may allow a corresponding error range, which may be set according to practical circumstances, such as-3 ° to 3 °, -5 ° to 5 °, or-8 ° to 8 °.

In some embodiments, the circuit board 41 of the knob assembly 40 may be fixed in the receiving cavity of the side pillar body 201 only by a screw structure. For example, the circuit board 41 may be fixed to the first sidewall 201a of the side post body 201 by two screws. Because the internal structure of the side column body 201 is very compact, the fixing scheme of the two screws is poor in manufacturability.

In some embodiments, the circuit board 41 of the knob assembly 40 may also be fixed in the receiving cavity of the side pillar body 201 by a snap structure, which is simple and has good manufacturability.

In some embodiments, to further improve the reliability of the fixing, the circuit board 41 of the knob assembly 40 may be fixed in the receiving cavity of the side pillar body 201 by the snap structure 411 and the screw structure 412. As shown in fig. 5, fig. 5 is a cross-sectional view of a partial structure of the heating element shown in fig. 1. One side of the circuit board 41 away from the heating body 10 is fixedly disposed on the inner wall of the accommodating cavity through the fastening structure 411, and one side of the circuit board 41 close to the heating body 10 is fixedly disposed on the inner wall of the accommodating cavity through the screw structure 412.

The snap structure 411 and the screw structure 412 are engaged, so as to prevent the circuit board 41 from moving in a direction parallel or perpendicular to the first sidewall 201a of the side pillar body 201, and to achieve reliable fixing of the circuit board 41.

Specifically, the inner wall of the accommodating cavity far away from the heating body 10 is provided with a first elastic buckle 411a and a second elastic buckle 411b at an interval as a buckle structure 411 for fixing the circuit board 41. As shown in fig. 5, the first and second snaps 411a and 411b may be provided at intervals. The specific structure of the first elastic buckle 411a and the second elastic buckle 411b may be any elastic buckle in the prior art, and will not be described herein again.

Further, the inner wall of the accommodating cavity far away from the heating body 10 is further provided with a limiting convex rib 411c, one side of the circuit board 41 far away from the heating body 10 is provided with a limiting groove 411d, and the limiting convex rib 411c is matched with the limiting groove 411d to further limit the position of the circuit board 41. As shown in fig. 5, the limiting rib 411c may be disposed between the first elastic buckle 411a and the second elastic buckle 411b, which is not limited in the present application and can be selected by a person skilled in the art according to actual requirements.

In some embodiments, the engagement between the limiting rib 411c and the limiting groove 411d can also play a guiding role. With reference to fig. 5, under the guiding action of the limiting rib 411c and the limiting groove 411d, the circuit board 41 can be assembled in place along the direction perpendicular to the paper surface, in the process of assembling the circuit board 41, the circuit board 41 can press the first elastic buckle 411a and the second elastic buckle 411b outward, that is, press the side away from the heating body 10, so that the first elastic buckle 411a and the second elastic buckle 411b deform, when the circuit board 41 is assembled in place, the first elastic buckle 411a and the second elastic buckle 411b rebound to the initial positions, so as to clamp the circuit board 41, thereby preventing the circuit board 41 from moving in the direction perpendicular to the paper surface when the knob is pressed, and playing a limiting role.

As shown in fig. 5, a side of the circuit board 41 close to the heating body 10 is fixed to the first sidewall 201a of the side pillar body 201 by a screw 412. For example, the circuit board 41 and the first sidewall 201a of the side pillar body 201 may be both provided with screw holes, and the screw 412 is disposed through the screw holes on the circuit board 41 and the first sidewall 201a of the side pillar body 201 to fix the circuit board 41. The screw hole on the first sidewall 201a of the side pillar body 201 can be far away from the first opening 201b, so that the interference between the knob body 42 and the screw 412 is avoided, and the screw 412 can be conveniently locked by a lower screwdriver.

When the knob assembly 40 is installed on the heating side post 20, the installation space is compact, and under the condition that the installation space of the knob assembly 40 is compact, the circuit board 41 is fixed in a manner that the buckling structure 411 is matched with the screw structure 412, so that the circuit board 41 can be reliably fixed, and meanwhile, the manufacturing is convenient. In this embodiment, the circuit board 41 is fixed only by the way of matching one screw 412 and the fastening structure 411, which is more convenient for installation.

Referring to fig. 5 and 6, fig. 6 is a schematic cross-sectional view of the heating side pillar shown in fig. 1. Further, a limiting convex pillar 413a is further arranged on one side of the side pillar body 201 close to the heating body 10, a limiting hole 413b is arranged on one side of the circuit board 41 close to the heating body 10, and the limiting convex pillar 413a is matched with the limiting hole 413b to further limit the position of the circuit board 41.

As shown in fig. 5, the limiting convex pillar 413a and the screw structure 412 are respectively disposed on two sides of the heating body 10 in the thickness direction, and the limiting convex pillar 413a is engaged with the limiting hole, so as to prevent the circuit board 41 from deflecting when the screw 412 is locked.

As shown in fig. 6, the position-limiting protrusion 413a may be disposed on the first sidewall 201a of the side pillar body 201. Of course, in some embodiments, the limiting protrusion 413a may also be disposed on a side wall of the side pillar body 201 opposite to the first side wall 201a, which is not limited in the present application and can be selected by a person skilled in the art according to actual requirements.

As described above, in the present embodiment, the combination of one screw 412, two elastic buckles (411a and 411b), the limiting convex rib 411c and the limiting groove 411d, and the limiting convex pillar 413a and the limiting hole 413b realizes the reliable fixation of the circuit board 41 in the case of a relatively compact installation space. In addition, in order to ensure the concentricity of the first opening 201b and the second opening 202b, the first sidewall 201a of the side pillar body 201 and the decoration 202 may be fixed by a snap structure.
