[0022] Example 1

[0023] See also Figure 1-5 The utility model provides the following technical solutions: a far-infrared radiation electric heater, comprising a lower shell 1, both ends of the lower side of the lower shell 1 are connected with mounting slots 7, a tightening component 8 is arranged inside the mounting slot 7, an upper shell 2 is connected to the top of the lower shell 1, a heating mechanism 5 is connected between the lower shell 1 and the upper shell 2, a square heat outlet hole 6 is arranged on the upper shell 2, equipment heat dissipation holes 4 are arranged on the upper shell 2 and on both sides of the square heat outlet hole 6, and a protective component 3 is arranged above the upper shell 2 and on the periphery of the equipment heat dissipation hole 4 and the square heat outlet hole 6.

[0024] Specifically, the protection component 3 includes a fixing frame 31, a mounting frame 32, a dustproof net 33, a connecting groove 34 and a connecting piece 35. The upper portion of the upper housing 2 is connected to the fixing frame 31, the upper portion of the fixing frame 31 is provided with the mounting frame 32, both ends of the interior of the mounting frame 32 are provided with connecting grooves 34, a connecting piece 35 is provided between the fixing frame 31 and the connecting groove 34, the interior of the mounting frame 32 is connected to the dustproof net 33,

[0025] By adopting the above technical solution, the installation frame 32 is placed above the fixed frame 31, and the installation frame 32 and the fixed frame 31 are connected by using the connecting piece 35 inside the connecting groove 34, so that the dustproof net 33 can be installed above the upper shell 2. Under the action of the fixed frame 31, the installation frame 32 and the dustproof net 33, it can be prevented that dust and other impurities in the external environment enter the device heat dissipation holes 4 and the square heat outlet holes 6 during subsequent use, and adhere to the internal components of the device heat dissipation holes 4 and the square heat outlet holes 6, affecting the use effect of the internal components of the device heat dissipation holes 4 and the square heat outlet holes 6.

[0026] Specifically, the connecting member 35 includes a connecting tube 351, a partition 352, a first spring 353, a moving rod 354, a plug-in rod 355 and a plug-in slot 356. The connecting tube 351 is connected to the inside of the connecting slot 34, the connecting tube 351 is connected to the inside of the connecting tube 352, the moving rods 354 are plugged into the inside of the connecting tube 351 and on both sides of the partition 352, the first spring 353 is connected between the partition 352 and the moving rod 354, the ends of the two moving rods 354 that are away from each other are connected to the plug-in rod 355, and the plug-in slot 356 is provided in the inside of the fixed frame 31 and at the position corresponding to the plug-in rod 355.

[0027] By adopting the above technical solution, the two moving rods 354 are first moved toward each other so that the two moving rods 354 move toward the inside of the connecting tube 351. The movement of the moving rods 354 drives the plug-in rod 355 to move and the first spring 353 to compress. Then the installation frame 32 is placed above the fixed frame 31. The plug-in rod 355 is then plugged into the plug-in slot 356. Then the moving rods 354 are released. The first spring 353 loses the external force and returns to its original state, driving the moving rods 354 to move.

[0030] When the present embodiment is used, the two moving rods 354 are first moved toward each other so that the two moving rods 354 move toward the inside of the connecting tube 351. The movement of the moving rods 354 drives the plug-in rod 355 to move and the first spring 353 to compress. Then, the installation frame 32 is placed above the fixed frame 31. The plug-in rod 355 is then plugged into the plug-in slot 356. Then, the moving rods 354 are released. The first spring 353 loses the external force and returns to its original state, driving the moving rods 354 to move. The movement of the moving rods 354 drives the plug-in rod 355 to move and plug into the plug-in slot 356, so that the dust screen 33 can be installed on the fixed frame 31. Above the upper housing 2, under the action of the fixing frame 31, the mounting frame 32 and the dustproof net 33, it is possible to prevent dust and other impurities in the external environment from entering the device heat dissipation holes 4 and the square heat outlet holes 6 during subsequent use, and adhering to the internal components of the device heat dissipation holes 4 and the square heat outlet holes 6, thereby affecting the use effect of the internal components of the device heat dissipation holes 4 and the square heat outlet holes 6. Then, the entire device is connected to the use site using the mounting card slot 7, and the heating mechanism 5 is started. The heat generated during the operation of the heating mechanism 5 is diffused to the peripheral environment through the square heat outlet holes 6 and the dustproof net 33, thereby achieving the heating purpose.
