Description

Technical Field

[0001] The utility model relates to a multifunctional fireplace fan which can stand, hang and be magnetically attracted, and relates to the technical field of fireplace fan equipment. Background Art

[0002] Fireplace fans are often used during use to spread heat evenly and increase indoor temperature faster.

[0003] The existing fireplace fans are mostly fixed structures, including standing type, wall-mounted clip type, and wall-mounted magnetic type. The standing type can only be placed on the fireplace countertop, the wall-mounted clip type needs to be installed with a hose clamp to be fixed on the fireplace pipe for use, and the wall-mounted magnetic type is only suitable for fireplaces with iron pipes, which is not easy to use. In order to improve the usability of fireplace fans, the existing technology adopts a variety of fixing methods. For example, the patent technology with announcement number CN212717290U discloses a fireplace fan, which includes a heat-conducting base, a heat dissipation component, a power generation chip and a drive component. The heat-conducting base includes a magnetic portion and a support portion. The magnetic portion is used to be fixed to the smoke pipe. The support portion is provided below the magnetic portion and is used to abut against the smoke pipe. The heat dissipation component is provided on the heat-conducting base, and the power generation chip is provided between the heat-conducting base and the heat dissipation component. The drive component includes a motor and blades. The motor is provided on the heat dissipation component, the power generation chip is electrically connected to the motor, and the output shaft of the motor is transmission-connected to the blades to drive the blades to rotate. The technical solution of the present utility model improves the scope of use of the fireplace fan, but in this structure the fan part is arranged at the front end of the support part, and is only connected to the air duct by magnetic attraction with a small area of the back plate. Although the support of the support part increases a certain stability, the firmness is insufficient, and the fan requires three brackets for connection, has poor thermal conductivity, and the fan startup time is long and slow. Moreover, this structure can only be fixed by wall-mounted buckles or magnetic attraction, and cannot be used in a standing position. The technical solution disclosed in the patent technology with announcement number CN213360482U can only be placed on a fireplace with a countertop for use, and cannot be hung on a chimney pipe for use, and the installation method is still relatively simple.

[0010] Furthermore, the motor mounting cavity 11 is located below the heat dissipation bracket 1, and a heat dissipation back plate 8 is provided on the back of the motor mounting 11.

DETAILED DESCRIPTION

[0021] See Figure 1-Figure 5 As shown, the technical solution adopted in this specific embodiment is: it includes a heat dissipation bracket 1, a heat-conducting base 2, a motor 4, and a fan blade 5. The bottom of the heat dissipation bracket 1 is connected to the top of the heat-conducting base 2, the motor 4 is installed in the heat dissipation bracket 1, and the fan blade 5 is connected to the output shaft end of the motor 4. The heat-conducting base 2 is an arc-shaped surface on the side opposite to the heat dissipation bracket 1 and is provided with a magnetic attraction strip 6. At least two magnetic attraction strips 6 are provided. The magnetic attraction strips are made of strong magnets to ensure the firmness of adsorption. In this embodiment, a free-installation structure of a fireplace fan is provided. By providing two magnetic attraction strips, they can be adsorbed with a magnetic arc-shaped surface structure, such as a curved table or an air duct structure, so that the fireplace fan can be adsorbed and fixed at will, with more adsorption angles, more convenient adjustment, and more conducive to heat diffusion. When used in a non-iron chimney, the fan and the chimney pipe can be fixed by passing a throat clamp through the hollow part of the heat-conducting base, and used in a suspended manner.

[0022] More specifically, the bottom of the heat-conducting base 2 is a flat placement end. When the use location lacks a magnetic adsorption structure and there are more flat placement locations for fireplaces, the fireplace fan can be directly placed on the flat surface and used arbitrarily.

[0023] In addition, a handle 9 is provided on the top of the heat dissipation bracket 1 to facilitate the transportation of the device and to prevent burns.

[0024] To be more specific, a magnetic stripe mounting groove 21 is provided in the curved surface on the back side of the thermal conductive base 2, a fixing hole 22 is provided in the magnetic stripe mounting groove 21, and a magnetic stripe fixing bracket 7 is provided in the magnetic stripe mounting groove 21. The magnetic stripe fixing bracket 7 is installed in the magnetic stripe mounting groove 21 by means of screws and the fixing holes 22. The magnetic stripe fixing bracket 7 is a "J"-shaped structure with an empty groove in the middle. In this embodiment, the superimposed thickness of the magnetic strip and the magnetic stripe fixing bracket matches the thickness of the magnetic stripe mounting groove. The outer surface of the magnetic stripe fixing bracket is flush with the curved surface of the thermal conductive base 2, and the adsorption is more firm during magnetic fixation. The hollow groove in the middle of the magnetic stripe fixing bracket has a better magnetic effect.

[0025] To be more specific, a thermoelectric power generation sheet 3 is provided at the bottom of the heat dissipation bracket 1, and the thermoelectric power generation sheet 3 is electrically connected to the motor 4. After the fireplace is used, the thermoelectric power generation sheet realizes self-generation to drive the motor, which is more convenient to use.

[0026] To be more specific, there is a motor mounting cavity 11 below the heat dissipation bracket 1, and a heat dissipation back plate 8 is provided on the back of the motor mounting 11. The bottom of the heat dissipation back plate 8 extends downward to form an extension plate 81, and the extension plate 81 extends beyond the bottom of the heat dissipation bracket 1 and abuts against the top of the heat conductive base 2.

[0027] To be more specific, the extension plate 81 and the top of the heat-conducting base 2 form a generator plate mounting groove, and the thickness of the generator plate mounting groove matches the thickness of the thermoelectric generator plate 3. In order to facilitate the installation of the thermoelectric generator plate, an extension plate is provided at the bottom of the heat dissipation back plate to form a mounting groove against the heat-conducting base, and the heat dissipation bracket is connected and fixed to the heat-conducting base by screws from the heat dissipation bracket, which also facilitates the replacement of the thermoelectric generator plate.

[0028] The working principle of the present invention: the installation method of the fan can be selected according to the actual situation of the fireplace. When the smoke pipe of the fireplace countertop is not made of iron material, it can be fixed and hung by a throat clamp. When the fireplace chimney pipe is made of iron, the curved surface side of the heat-conducting base 2 can be directly brought into contact with it, and magnetic fixation is performed through the magnetic strip 6. Since the double magnetic strip 6 is used as the adsorption body, the adsorption effect is good. At the same time, fixing screw holes 23 are also provided on the heat-conducting base 2. When the curved fixing surface cannot be adsorbed, screws can be used for fixation, and the adsorption of the magnetic strip 6 can also be used to enhance the fixing effect. When the fan does not need to be fixedly installed, it can be directly placed on a fireplace with a flat surface for use, and the installation and use methods are more diversified.

[0029] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
