[0026] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0028] like Figure 1-4 As shown, an electric heater includes two columns 1 and a heating plate 2 disposed between the two columns 1. The two columns 1 are respectively provided with a front column groove 101 and a rear column groove 102 arranged along the length direction on their opposite sides. A back plate 3 connecting the two columns 1 is provided between the two rear column grooves 102. A protective net 4 is provided between the two columns 1. The lower part of the protective net 4 is inserted into the front column grooves 101 on both sides, and the upper part of the protective net 4 is bent backward and inserted into the rear column grooves 102 on both sides. An end cap 5 for locking the protective net is connected to the upper end of the column 1. During assembly, the back plate 3 is inserted between the rear column grooves 102, and the lower part of the protective net 4 is inserted from top to bottom into the front column grooves 101 on both sides. Then, the upper part of the protective net 4, which is bent backward, is inserted from top to bottom into the rear column grooves 102 on both sides. Finally, the protective net 4 is locked between the two columns 1 by covering the decorative end caps 5 on the columns 1. In this case, the columns, back plate, protective net and end caps are connected by plug-in, which facilitates quick assembly and disassembly and simplifies the overall structure.

[0029] like Figure 1-4 As shown, the column 1 includes a U-shaped column outer shell plate 103 and a column side plate 104 disposed on the open end of the U-shaped column outer shell plate 103. The front column groove 101 and the rear column groove 102 are respectively disposed on the column side plate 104, which can enable the column to be quickly assembled.

[0030] like Figure 1-4As shown, the upper part of the back panel 3 is inserted into the rear column grooves 102 on both sides, and the lower part of the back panel 3 is bent forward and inserted into the front column grooves 101 on both sides. The lower side of the back panel 3 is provided with outwardly extending back panel connecting parts 301 that connect to the two columns 1. The back panel connecting parts 301 are connected to the lower end of the columns 1. When assembling the back panel 3, the upper part of the back panel 3 is inserted from bottom to top into the rear column grooves 102 on both sides, and the lower part of the back panel 3, bent forward, is inserted from bottom to top into the front column grooves 101 on both sides, so that the upper end of the back panel 3 abuts against the protective net 4. Finally, the back panel connecting parts 301 are fixed to the two columns 1 with screws, achieving quick assembly and disassembly of the back panel.

[0031] like Figure 4 As shown, the lower side of the back plate 3 has a back plate through hole 302, and a detachable circuit board bracket 6 is provided inside the back plate through hole 302. The circuit board bracket 6 is provided with a circuit board 7 connected to the heating plate 2 for controlling the operation of the heating plate 2. One of the columns 1 has a touch screen 8 on its side, which is connected to the circuit board 7 for inputting control commands and displaying working information. During operation, control commands are input to the circuit board 7 through the touch screen 8, so that the circuit board 7 controls the heating plate 2 to work intelligently.

[0032] like Figure 4 As shown, the circuit board bracket 6 is equipped with an emergency switch 9 that controls the power supply to and from the heating plate 2. The power supply to and from the heating plate 2 can be directly controlled by the emergency switch 9, so that the electric heater can still work even if the circuit board 7 is damaged.

[0033] like Figure 1-4 As shown, a reflector 10 is provided between the two columns 1, with the open end of the reflector 10 facing the protective net 4. The heating plate 2 is placed inside the reflector 10. Multiple reflector mounting brackets 11 are provided between the reflector 10 and the column side plate 104. The reflector mounting brackets 11 and the column side plate 104 are connected by screws, so that the reflector 10 is firmly installed between the two columns 1. The reflector 10 can maximize the outward reflection of the heat generated by the heating plate 2.

[0034] like Figure 1-4 As shown, the upper cover of the reflector 10 is provided with a partition baffle 12, and baffle connectors 13 are respectively provided on both sides of the partition baffle 12. The upper end of the column side plate 104 is provided with a baffle locking hole 14 for locking the baffle connectors 13. The rear side of the partition baffle 12 abuts against the protective net 4. By cooperating with the baffle locking hole 14 with screws, the baffle connectors 13 are locked to the upper end of the column side plate 104, thereby making the partition baffle 12 securely installed between the two columns 1. The partition baffle 12 can separate the protective net 4 and the reflector 10, improving the safety of use.

[0035] like Figure 1-4As shown, protective netting 4 has protective netting connectors 15 on both sides of its upper portion, and the upper end of the column side plate 104 has protective netting locking holes 16 for locking the protective netting connectors 15. By engaging the screws with the protective netting locking holes 16, the protective netting connectors 15 are locked onto the upper end of the column side plate 104, thereby ensuring that the protective netting 4 is securely installed between the two columns 1. The protective netting connectors 15 are located on the upper side of the baffle connectors 13, and the protective netting connectors 15 have clearance recesses 17 for avoiding the baffle locking screws, so that the screws can lock the partition baffle 12 onto the column side plate 104 through the clearance recesses 17.

[0036] like Figure 1-4 As shown, a stand 18 is connected to the lower side of the back panel connecting part 301, and a caster wheel 19 is connected to the lower side of the stand 18 to facilitate moving the electric heater; a cord winder 20 is provided on the rear side of the back panel 3 to facilitate adjusting the power cord length and retracting the power cord.

[0037] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
