Description

Technical area

[0001] The present invention relates to a multifunctional fireplace fan that can be mounted standing, hanging or magnetically and relates to the technical field of fireplace fan devices. Background technology

[0002] When operating a fireplace, a fireplace fan is often used to distribute heat evenly and increase room temperature more quickly.

[0003] Existing fireplace fans usually have a fixed structure, such as pedestal fans, wall-mounted fans with brackets, or magnetic wall mounting. Pedestal fans can only be placed on the fireback, while wall-mounted fans with brackets require the installation of a hose clamp on the chimney pipe, and magnetic wall mounting is only suitable for fireplaces with iron pipes, which limits their usability.

[0004] To improve the usability of chimney fans, various mounting methods have been used in existing technology. For example, patent publication number CN212717290U discloses a chimney fan comprising a heat conduction base, a cooling component, a generator chip, and a drive component. The heat conduction base consists of a magnet portion and a support portion. The magnet portion is used for mounting on the flue pipe, while the support portion is located below the magnet portion and serves as support to the flue pipe. The cooling component is attached to the heat conduction base, the generator chip is located between the heat conduction base and the cooling component, and the drive component includes a motor and fan blades.The motor is installed in the cooling component, the generator chip is electrically connected to the motor, and the output shaft of the motor is connected to the fan blades to drive them.

[0005] This technical solution expands the application range of the chimney fan, but in this structure, the fan section is mounted at the front end of the support section and is magnetically attached to the flue pipe only through a small rear wall area. Although the support section provides a certain degree of stability, the attachment is not sufficiently strong. Furthermore, this fan requires three brackets, which reduces thermal conductivity and lengthens and slows down the fan's start-up time.

[0006] This structure can only be used by wall mounting with brackets or magnetic fastening and is not suitable for freestanding use. The technical solutions disclosed in the patent publication number CN213360482U can only be used on fireplaces with a shelf and are not suitable for suspension from flues, which further limits the installation options. Content of the utility model

[0007] The objective of this utility model is to address the deficiencies or inadequacies of existing technology and provide a multifunctional fireplace fan that can be mounted vertically, suspended, or magnetically. By using a magnetic heat-conducting base with a curved surface, the fan can be used not only on a flat surface but also attached to a wall-mounted iron chimney pipe. Furthermore, it can be hung on a non-ferrous chimney pipe using a hose clamp, offering a wide range of uses and providing a better user experience.

[0008] To achieve this goal, the utility model uses the following technical solutions: It includes a cooling frame (1), a heat conduction base (2), a motor (4), and fan blades (5). The bottom of the cooling frame (1) is connected to the top of the heat conduction base (2), the motor (4) is installed in the cooling frame (1), and the fan blades (5) are connected to the output shaft of the motor (4). The side of the cooling frame (1) opposite the heat conduction base (2) is arc-shaped and provided with magnetic strips (6), and the bottom of the heat conduction base (2) is a flat support surface. The upper part of the cooling frame (1) is equipped with a handle (9).

[0009] Furthermore, the back of the thermal base (2) is provided with a magnetic strip mounting slot (21).

[0010] In addition, the magnetic stripe mounting slot (21) has mounting holes (22), and a magnetic stripe holder (7) is installed in the magnetic stripe mounting slot (21) and is fixed in the mounting holes (22) by means of screws.

[0011] The magnetic strip holder (7) has a Z-shaped structure and the middle part of the holder is hollow.

[0012] The bottom of the cooling frame (1) is equipped with a thermoelectric generator (3) which is electrically connected to the motor (4).

[0013] A motor installation space (11) is located below the cooling frame (1), and the rear of the motor installation space (11) is equipped with a cooling back plate (8) that extends downwards to an extension plate (81). The extension plate (81) protrudes beyond the bottom of the cooling frame (1) and rests against the top of the heat conduction base (2).

[0014] The extension plate (81) and the top of the heat conducting base (2) form a mounting slot for the thermoelectric generator, the thickness of which corresponds to that of the thermoelectric generator (3).

[0015] At least two magnetic strips (6) are provided.

[0016] By applying the above-mentioned technical solutions, this utility model offers the following advantages: By using a magnetic heat-conducting base with a curved surface, the fan can be used not only on a flat surface but also attached or hung on a curved surface. This offers a wide range of usage options and improves the user experience. Description of the illustrations

Detailed embodiments

[0024] With reference to the Fig.The technical solution of this specific embodiment is as follows: It includes a cooling frame (1), a heat conduction base (2), a motor (4), and fan blades (5). The bottom of the cooling frame (1) is connected to the top of the heat conduction base (2), the motor (4) is installed in the cooling frame (1), and the fan blades (5) are connected to the output shaft of the motor (4). The side of the cooling frame (1) opposite the heat conduction base (2) is arc-shaped and provided with at least two magnetic strips (6). The magnetic strips are made of strong magnets to ensure the strength of the attachment. In this embodiment, an installation-free structure for the fireplace fan is provided.The arrangement of two magnetic strips allows the fan to be attached to a magnetic curved surface, such as a curved tabletop or pipe, allowing for flexible mounting and easier adjustment, as well as improving heat distribution. When used on non-ferrous chimneys, the fan can be secured and suspended with a hose clamp through the hollow part of the heat-conducting base.

[0025] Specifically, the bottom of the heat-conducting base (2) is a flat surface. If the installation site does not have a magnetic mounting structure and there are many flat surfaces, the fireplace fan can be placed directly on a flat surface and used as desired.

[0026] In addition, the upper part of the cooling frame (1) is equipped with a handle (9) to facilitate the transport of the device and to avoid burns.

[0027] Specifically, the back of the thermal conduction base (2) is provided with a magnetic stripe mounting slot (21). The magnetic stripe mounting slot (21) has mounting holes (22), and a magnetic stripe holder (7) is installed in the magnetic stripe mounting slot (21) and secured by screws in the mounting holes (22). The magnetic stripe holder (7) has a Z-shaped structure, and the center part of the holder is hollow. In this embodiment, the combined thickness of the magnetic stripes and the magnetic stripe holder corresponds to the thickness of the magnetic stripe mounting slot. The outer surface of the magnetic stripe holder is flush with the arcuate surface of the thermal conduction base (2), enabling a firmer attachment when magnetically fixed. The hollow center part of the magnetic stripe holder improves the magnetic effect.

[0028] Specifically, the base of the cooling frame (1) is equipped with a thermoelectric generator (3) that is electrically connected to the motor (4). After the fireplace is used, the motor is powered by the thermoelectric generator, making it easier to use.

[0029] Specifically, a motor installation space (11) is located below the cooling frame (1), and the rear of the motor installation space (11) is equipped with a cooling back plate (8) that extends downward to an extension plate (81). The extension plate (81) protrudes beyond the bottom of the cooling frame (1) and rests against the top of the heat conduction base (2).

[0030] Specifically, the extension plate (81) and the top surface of the heatsink base (2) form a mounting slot for the thermoelectric generator, the thickness of which corresponds to that of the thermoelectric generator (3). To facilitate the installation of the thermoelectric generator, the extension plate on the bottom of the cooling back plate forms a mounting slot together with the heatsink base. The cooling frame and the heatsink base are connected by screws, which also facilitates the replacement of the thermoelectric generator.

[0031] The working principle of this invention: The installation method of the fan can be selected according to the actual circumstances of the chimney. If the fireplace backing is made of non-ferrous material, the fan can be fixed and suspended with a hose clamp. If the chimney pipe is made of iron, the arc-shaped side of the heat conduction base (2) can be directly contacted with it and magnetically fixed by the magnetic strips (6). Since two magnetic strips (6) are used as the main fixing elements, the fixing effect is good. In addition, fixing holes (23) are provided on the heat conduction base (2). If the arc-shaped fixing surface is non-magnetic, screws can be used for fixing, which, in combination with the magnetic strips (6), enhances the fixing effect.If the fan does not need to be permanently installed, it can be used directly on a flat surface of the fireplace, which offers a variety of installation and usage options.

[0032] The above is only intended to explain the technical solutions of this invention and is not intended to be limiting. Those skilled in the art may make other modifications or equivalent substitutions to the technical solutions of this invention, as long as they do not depart from the spirit and scope of the technical solutions of this invention, and they should fall within the scope of the claims of this invention.
