[0002] An electric fireplace is a heating device that uses electricity as its energy source. It is suitable for modern homes, offices, and other places that require localized heating and can effectively improve comfort in winter.
[0003] When using an electric fireplace, electricity is supplied, causing the heating elements inside the fireplace to heat the air. The heated air is then exhausted through ventilation holes, heating the room. LED lights inside the fireplace generate flame effects, appearing from the flame nozzles to simulate flames. However, when the air enters the fireplace through the ventilation holes, impurities may be present. These impurities can be carried into the room with the heated air, potentially affecting the fireplace's performance. Utility Model Content
[0004] The technical problem this invention aims to solve is that when air enters the furnace body through the ventilation holes, there are impurities in the air. When the heated air is discharged, these impurities are carried into the room, thus affecting the performance of the electric fireplace.

[0006] The effects achieved by the above components are as follows: When the electric fireplace is in use, it is powered on, and the electric heating element inside the fireplace heats the air. After the air enters the fireplace, it is filtered by a filter to remove impurities. The filtered and heated air is then discharged through the ventilation holes, thus heating the room. There are also LED lights inside the electric fireplace that generate flame light and shadow, which emerge from the flame port to simulate flames.
[0007] Preferably, the furnace body has an installation assembly on the side of the inner wall near the ventilation hole. The furnace body is equipped with a filter device by the installation assembly. The filter device includes a square tube, which is located on the side of the inner wall of the furnace body near the ventilation hole.

[0008] The effect achieved by the above components is as follows: The installation assembly installs the filter device on the inner wall of the furnace body near the ventilation hole. When the electric fireplace is in use, air passes through the ventilation hole on the surface of the furnace body and enters the furnace body. Impurities in the air are first fixed to the filter screen inside the square tube for filtering large particles. The large particles intercepted by the filter are stored in the storage slots on both sides of the square tube. Then, after the air reaches the activated carbon plate, dust, odors and harmful gases in the air are adsorbed, completing the air filtration. The filtered and heated air is then discharged through the ventilation hole. By using the filter device, the air entering the furnace body can be filtered, preventing impurities in the heated air from entering the room with the air, thereby improving the performance of the electric fireplace.
[0009] Preferably, guide blocks are provided on both sides of the square tube, and the guide blocks are located on the side of the filter screen away from the activated carbon plate.
[0010] The effect achieved by the above components is as follows: by fixing the guide plate on the side of the filter screen away from the activated carbon plate, the large particles of debris intercepted and filtered by the filter screen are guided, so that the large particles of debris can reach the storage tank better by gravity.
[0011] Preferably, grooves are formed on both sides of the square tube, and auxiliary plates are provided inside the storage slots on both sides of the square tube, with one side of the auxiliary plate located inside the grooves formed on both sides of the square tube.
[0012] The effect achieved by the above-mentioned components is that when removing large particles of debris inside the storage tank, the auxiliary plate can be moved to move between the storage tank and the groove of the square tube, and then the large particles of debris inside the storage tank are carried away from the storage tank, thereby improving the performance of the filtration device.
[0013] Preferably, the square tube is provided with a plurality of anti-slip blocks on both sides, and the plurality of anti-slip blocks increase the friction on both sides of the square tube.
[0014] The effect achieved by the above components is to increase the friction on both sides of the square tube by fixing several anti-slip blocks on both sides, making it easier for the operator to move the square tube.
[0015] Preferably, the mounting assembly includes a placement block, bolts, and a mounting block. The placement block is located on the inner wall of the furnace body near the ventilation hole. The bolts are inserted into the placement block to fix the mounting block. One side of the mounting block is connected to a square tube.
[0016] The effect achieved by the above components is as follows: when installing and fixing the filter device, the square tube can be moved so that the mounting block fixed on one side of the square tube can be inserted into the placement block fixed on the inner wall of the furnace. Then, the bolt can be rotated so that the bolt passes through the placement block and is threadedly fixed to the mounting block. Then the position of the square tube can be fixed. By using the installation components, the filter device can be quickly installed on the inner wall of the furnace near the ventilation hole, which facilitates the subsequent use of the filter device.
[0017] Preferably, an operating block is provided on one side of the bolt, and the operating block increases the size of one side of the bolt.
[0018] The effect achieved by the above components is to increase the contact area between the operator and the bolt by using the operating block fixed on one side of the bolt, making it easier for the operator to rotate the bolt.
[0019] Preferably, a washer is provided on one side of the bolt, and the washer increases the contact area between the bolt and the placement block.
[0020] The effect achieved by the above components is that by abutting the bolts and the washers, the contact area between the bolts and the mounting block is increased, allowing the bolts to better fix the mounting block.

A filter device 4 is located inside the fireplace body 1 near the ventilation holes 2, filtering the air entering the fireplace body 1. When the electric fireplace is in use, electricity is supplied, causing the heating element inside the fireplace body 1 to heat the air. After the air enters the fireplace body 1, it is filtered of impurities by the filter device 4. The filtered and heated air is then discharged through the ventilation holes 2, thus heating the room. LED lights inside the electric fireplace generate flame light and shadow, which emerge from the flame port 3 to simulate flames.
[0033] Figures 1 to 4The furnace body 1 shown has an installation component 5 on the inner wall near the ventilation hole 2. The furnace body 1 is equipped with a filter device 4 by the installation component 5. The filter device 4 includes a square tube 41, which is located on the inner wall of the furnace body 1 near the ventilation hole 2. The square tube 41 has two filter screens 42 inside, and an activated carbon plate 43 is located in the middle area of the two filter screens 42 inside the square tube 41. Storage slots 44 are opened on both sides of the lower end of the inner wall of the square tube 41. The installation component 5 installs the filter device 4 on the inner wall of the furnace body 1 near the ventilation hole 2. When the electric fireplace is in use, air passes through the ventilation hole 2 on the surface of the furnace body 1 and enters the interior of the furnace body 1. The impurities in the air are first fixed to the filter screen 42 inside the square tube 41 for filtering large particles. The large particles intercepted by the filter are stored in the storage slots 44 on both sides of the square tube 41. Then, after the air reaches the activated carbon plate 43, dust, odors and harmful gases in the air are adsorbed, completing the air filtration. The filtered and heated air is then discharged through the ventilation hole 2. By using the filter device 4, the air entering the furnace body 1 can be filtered, preventing impurities in the heated air from entering the room with the air, thereby improving the performance of the electric fireplace.
[0034] Figures 1 to 4 The square tube 41 shown has guide blocks 45 on both sides, with the guide blocks 45 positioned on the side of the filter screen 42 away from the activated carbon plate 43. By fixing the guide blocks to the side of the filter screen 42 away from the activated carbon plate 43, large particles intercepted and filtered by the filter screen 42 are guided, allowing them to reach the storage tank 44 more effectively by gravity. Grooves 46 are formed on both sides of the square tube 41, and auxiliary plates 47 are provided inside the storage tanks 44 on both sides of the square tube 41. One side of the auxiliary plates 47 is located inside the grooves 46 on both sides of the square tube 41. When removing large particles from the storage tank 44, the auxiliary plates 47 can be moved, allowing them to move between the storage tank 44 and the grooves 46 of the square tube 41, thus carrying the large particles out of the storage tank 44 and improving the effectiveness of the filtration device 4. Several anti-slip blocks 48 are provided on both sides of the square tube 41, increasing the friction on both sides of the square tube 41. By fixing several anti-slip blocks 48 on both sides of the square tube 41, the friction on both sides of the square tube 41 is increased, making it easier for the operator to move the square tube 41.

One side of the mounting block 53 is connected to the square tube 41. When installing and fixing the filter device 4, the square tube 41 can be moved so that the mounting block 53 fixed on one side of the square tube 41 is inserted into the placement block 51 fixed on the inner wall of the furnace body 1. Then, the bolts 52 are rotated so that the bolts 52 pass through the placement block 51 and are threadedly fixed to the mounting block 53, thus completing the position fixing of the square tube 41. By using the installation assembly 5, the filter device 4 can be quickly installed on the inner wall of the furnace body 1 near the ventilation hole 2, facilitating subsequent use of the filter device 4.
[0036] Figures 1 to 4 An operating block 54 is provided on one side of the bolt 52, which increases the size of one side of the bolt 52. By fixing the operating block 54 to one side of the bolt 52, the contact area between the operator and the bolt 52 is increased, making it easier for the operator to rotate the bolt 52. A washer 55 is provided on one side of the bolt 52, which increases the contact area between the bolt 52 and the placement block 51. The contact area between the bolt 52 and the placement block 51 is increased by the bolt 52 abutting against the washer 55, allowing the bolt 52 to better secure the mounting block 53.
[0037] Working principle: When using the electric fireplace, electricity is turned on, and the electric heating element inside the furnace body 1 heats the air. After the air enters the furnace body 1, it is filtered by the filter device 4 to remove impurities. The filtered and heated air is then discharged through the ventilation hole 2, thus heating the room. Inside the electric fireplace, there are also LED lights that generate flame light and shadow, which emerge from the flame port 3 to simulate flames. The installation component 5 installs the filter device 4 on the inner wall of the furnace body 1 near the ventilation hole 2. When the electric fireplace is in use, air passes through the ventilation hole 2 on the surface of the furnace body 1 and enters the interior of the furnace body 1. The impurities in the air are first fixed to the filter screen 42 inside the square tube 41 for filtering large particles. The large particles intercepted by the filter are stored in the storage slots 44 on both sides of the square tube 41. Then, after the air reaches the activated carbon plate 43, dust, odors and harmful gases in the air are adsorbed, completing the air filtration. The filtered and heated air is then discharged through the ventilation hole 2. By using the filter device 4, the air entering the furnace body 1 can be filtered, preventing impurities in the heated air from entering the room with the air, thereby improving the performance of the electric fireplace.
[0038] When installing and fixing the filter device 4, the square tube 41 can be moved so that the mounting block 53 fixed on one side of the square tube 41 can be inserted into the placement block 51 fixed on the inner wall of the furnace body 1. Then, the bolt 52 can be rotated so that the bolt 52 passes through the placement block 51 and is threadedly fixed to the mounting block 53. Then the position of the square tube 41 can be fixed. By using the installation component 5, the filter device 4 can be quickly installed on the inner wall of the furnace body 1 near the ventilation hole 2, which will facilitate the subsequent use of the filter device 4.
