Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0035] The utility model provides a fireplace fan.

[0036] In the embodiment of the present utility model, refer to Figure 1 and Figure 2 The fireplace fan includes a base 10, a heat conductive member 20, a temperature difference power generation mechanism 30, a motor 40, a fan blade 50 and a magnetic member 60. The heat conductive member 20 is arranged on the base 10; the motor 40 is arranged on the heat conductive member 20 and is electrically connected to the temperature difference power generation mechanism 30; the fan blade 50 is connected to the output shaft of the motor 40; the magnetic member 60 is installed on the base 10 for being adsorbed on the smoke pipe.

[0037] Specifically, when the fireplace fan is placed flat on the fireplace platform in a normal manner, the heat emitted by the fireplace can be transferred to the temperature difference power generation mechanism 30 through the base 10 and the heat conductor 20. The temperature difference power generation mechanism 30 will generate electrical energy after being heated, and transfer the electrical energy to the motor 40, allowing the motor 40 to drive the fan blades 50 to rotate, thereby realizing the heat dissipation of the fireplace by the fireplace fan.

[0038] When the fireplace fan cannot be placed on the top of the fireplace, the magnetic suction member 60 only needs to be adsorbed on the smoke pipe of the fireplace, so that the fireplace fan can be fixed on the fireplace through the magnetic suction member 60.

[0039] From the above installation method, the fireplace fan of this embodiment is adsorbed on the smoke pipe of the fireplace by setting a magnetic suction part 60, which increases the installation method of fixing the fireplace fan on the fireplace. The fireplace fan can also be placed flat on the platform of the fireplace in the usual way, thereby improving the versatility of the fireplace fan.

[0040] In one embodiment, referring to Figure 1 and Figure 2 The heat conducting member 20 includes a first heat conducting member 21 and a second heat conducting member 22. The first heat conducting member 21 is connected to the base 10. The temperature difference power generation mechanism 30 is connected to the side of the first heat conducting member 21 facing away from the base 10. The second heat conducting member 22 is connected to the side of the temperature difference power generation mechanism 30 facing away from the first heat conducting member 21.

[0041] Specifically, the temperature difference power generation mechanism 30 is fixed between the first heat conductive member 21 and the second heat conductive member 22. When heat is transferred from the base 10 to the first heat conductive member 21 and then transferred to the temperature difference power generation mechanism 30 through the first heat conductive member 21, the temperature difference power generation mechanism 30 is heated to generate electricity. When the fireplace fan is adsorbed on the smoke pipe through the magnetic member 60, the heat of the fireplace will be transferred to the temperature difference power generation mechanism 30 through the second heat conductive member 22, so that the temperature difference power generation mechanism 30 is heated to generate electricity, thereby ensuring that the fireplace fan and the fireplace can transfer heat in different installation methods, thereby ensuring the normal operation of the fireplace fan.

[0042] In one embodiment, referring to Figure 1 and Figure 2 The first heat conducting member 21 and the second heat conducting member 22 are both aluminum metal heat conducting members. In this way, the first heat conducting member 21 and the second heat conducting member 22 heat transfer blocks made of aluminum metal are used, and the weight of the first heat conducting member 21 and the second heat conducting member 22 is relatively light, which further reduces the weight of the fireplace fan.

[0043] Optional, see Figure 1 and Figure 2 The first heat-conducting member 21 is an I-shaped heat-conducting member; the second heat-conducting member 22 is a plum blossom-shaped heat-conducting member.

[0044] In this embodiment, since the first heat conductive member 21 is located at the bottom adjacent to the fireplace fan, the first heat conductive member 21 is configured to be an I-shaped member to further enhance the structural strength of the first heat conductive member 21. The second heat conductive member 22 is located at a position adjacent to the magnetic member 60 of the fireplace fan, so the second heat conductive member 22 is configured to be a plum blossom shape, so that the heat transfer area of ​​the second heat conductive member 22 is wider, which facilitates the heat transfer of the fireplace to the second heat conductive member 22, improves the heat transfer effect of the fireplace fan, and thus allows the fireplace fan to heat up and operate faster.

[0045] In other embodiments, the shapes of the first heat conducting member 21 and the second heat conducting member 22 may also be other shapes as long as they can facilitate heat transfer.

[0046] Further, see Figure 1 and Figure 2 The surfaces of the first heat conducting member 21 and the second heat conducting member 22 are provided with a plurality of indentations, and the plurality of indentations are arranged at intervals. In this way, the plurality of indentations can increase the surface area of ​​the first heat conducting member 21 and the second heat conducting member 22, thereby improving the heat transfer effect of the fireplace fan, and making the fireplace fan run faster.

[0047] Optional, see Figure 1 and Figure 2 The temperature difference power generation mechanism 30 is a power generation chip. The power generation chip is manufactured based on the Seebeck effect principle and using unique thin film technology. Like semiconductor refrigerators, the production process of the temperature difference power generation chip combines microelectronic thin film and MEMS-like chip technology. The power generation chip has the following advantages: the temperature change in the 1mm2 area can generate a voltage of 0.5-5V, which can realize self-sustaining power supply; small size, fast response time; the power supply equipment made of the chip does not need frequent maintenance, works for a long time, and has a long life.

[0048] In one embodiment, referring to Figure 1 and Figure 2 The magnetic attraction member 60 includes a mounting plate 61 and a magnet 62. The mounting plate 61 is detachably connected to the base 10 and is enclosed with the base 10 to form a mounting position; the magnet 62 is installed in the mounting position.

[0049] The mounting press plate 61 is detachably connected to the base 10 , so that the magnet 62 can be fixed in the mounting position through the mounting press plate 61 , which facilitates the installation and removal of the magnet 62 , thereby improving the convenience of installing the fireplace fan in the fireplace.

[0050] In one embodiment, referring to Figure 1 and Figure 2 The fireplace fan further includes a rear baffle 70 , which is detachably connected to the heat conducting member 20 and is disposed opposite to the fan blade 50 .

[0051] Specifically, the rear baffle 70 is connected to the first heat conducting member 21 of the heat conducting member 20 , which not only increases the heat transfer area of ​​the heat conducting member 20 , but also the motor 40 of the fireplace fan is actually installed on the rear baffle 70 , thereby improving the installation stability of the motor 40 and the fan blades 50 .

[0052] Optionally, the rear baffle 70 is provided with a plurality of mounting holes, and the plurality of mounting holes are arranged at intervals, so that the motor 40 can be fixed to the rear baffle 70 through the mounting holes.

[0053] In one embodiment, referring to Figure 1 and Figure 2 The fireplace fan further includes a handle 80 , which is connected to the heat conducting member 20 and spaced apart from the fan blade 50 .

[0054] In this embodiment, the handle 80 is fixed to the top of the second heat conductive member 22 of the heat conductive member 20. Thus, when the fireplace fan stops running and the temperature is lowered, the user can conveniently carry the fireplace fan through the handle 80, thereby improving the convenience of using the fireplace fan.

[0055] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
