Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to an improved oscillating fireplace fan. Background Technology

[0002] A fireplace fan is an auxiliary device used to improve the heating efficiency of a fireplace. Its core function is to blow the hot air generated by the fireplace evenly into the room to improve temperature distribution. The fan is driven by thermal power (thermal difference power generation) or electricity to rotate and blow the hot air above the fireplace horizontally. Some products support intelligent temperature control to adjust the speed.

[0003] Patent document CN210565253U discloses an oscillating fireplace fan. "In this utility model, the oscillating fireplace fan, when the oscillating motor drives the connecting rod to rotate, the connecting rod drives the rocker arm to rotate, the rocker arm rotates, which in turn drives the oscillating motor to oscillate, the oscillating motor drives the motor housing to oscillate, the fan motor located inside the motor housing rotates with the motor housing, and the fan blades rotate with the fan motor, thereby achieving the oscillating function." While the oscillating fireplace fan in the patent document achieves the utilization of fireplace heat and the oscillating function of the fan, it suffers from problems such as complex mechanical structure, low thermal energy generation efficiency, poor reliability of the oscillating mechanism, high noise and vibration, high maintenance difficulty, and poor safety and user experience.

[0024] Please see Figures 1-7 An improved oscillating fireplace fan;

[0025] The fireplace fan base includes a fireplace fan base 1, a fan frame 2, and a fan cover 3. The fan frame 2 is installed inside the fireplace fan base 1, and the fan cover 3 is installed on the top and bottom of the fan frame 2. The fireplace fan base 1 includes a base 11, a power supply 12, a base body 13, and an adjustment component 14. The base body 13 is C-shaped. The base 11 is installed on one side of the base body 13, the power supply 12 is embedded between the base 11 and the base body 13, and the adjustment component 14 is installed through the other side of the base body 13. A connection hole 15 for connecting to the adjustment component 14 is opened on one side of the base body 13, and mounting holes 16 are symmetrically opened on one side of the bottom of the base body 13. Small grooves 17 are evenly distributed on the inner wall of the base body 13.

[0026] The oscillating fireplace fan mainly consists of a fireplace fan base 1, a fan frame 2, and a fan cover 3. The base body 13 of the fireplace fan base 1 provides a mounting point for the fan frame 2, allowing the fan frame 2 to be installed inside the fireplace fan base 1. The fan frame 2 is connected to the fireplace fan base 1 as a boom through an adjusting component 14. The fan frame 2 can rotate 180 degrees within the base body 13 of the fireplace fan base 1, thereby expanding the air delivery range, simplifying the mechanical structure, improving stability, and reducing unnecessary mechanical parts through the boom design, thus reducing manufacturing and assembly difficulty and improving overall reliability. When the oscillating fireplace fan is in use, it is supported from the bottom by the base 11. The base 11 is fixed to one side of the base body 13 by bolts passing through the mounting holes 16. The small grooves 17 opened on the base body 13 can play a role in heat dissipation.

[0027] The fan frame 2 includes a fan mount 21, a motor mount 22, a fan blade 23, and a drive motor 24. The fan mount 21 is installed inside the base body 13, the motor mount 22 is installed inside the fan mount 21, the fan blade 23 is rotatably installed at the bottom center of the motor mount 22, and the drive motor 24 is installed at the top center of the motor mount 22. The drive motor 24 and the fan blade 23 are connected by a rotating shaft.

[0028] The fan mount 21 in the fan frame 2 provides a position for the installation of the motor frame 22. The motor frame 22 provides a position for the installation of the drive motor 24 and the fan blades 23, so that the connection end of the drive motor 24 and the fan blades 23 are connected. After the drive motor 24 is powered on, it converts electrical energy into kinetic energy, thereby driving the fan blades 23 at the output end to rotate at high speed. The rotation of the fan blades 23 blows the hot air generated by the fireplace evenly into the room.

[0029] The fan frame 21 is a circular groove type. One side of the fan frame 21 is connected to the base 11 through a circular hole. The other side of the fan frame 21 has a connecting hole body 25 corresponding to the connecting hole 15. The inner walls of both sides of the fan frame 21 are symmetrically provided with mounting platforms 26, and the top of the mounting platform 26 is connected to the motor frame 22 by screws. Several U-shaped grooves 27 are evenly provided on the mounting platform 26. The top and bottom circular surfaces of the fan frame 21 are provided with outer cover holes 28.

[0030] The fan frame 2 is connected to the base body 13 via the fan seat frame 21. During installation, the connecting hole 15 corresponds to the connecting hole body 25 and is connected by a fastener. On the other side of the fan seat frame 21, the fastener passes through the round hole and connects to the base body 13 and the base 11. The mounting platform 26 is used to support the motor frame 22 and provide it with an installation position. The U-shaped groove 27 makes the connection between the fan seat frame 21 and the motor frame 22 more stable. Moreover, through structural optimization, vibration transmission is reduced, which effectively reduces noise. The outer cover hole 28 provides connection space for the screws that fix the fan outer cover 3.

[0031] The motor frame 22 has a concave profile in cross section. The top center of the motor frame 22 is provided with a central groove 221. The interior of the central groove 221 is connected to the drive motor 24. A through hole 222 is provided at the bottom of the central groove 221.

[0032] The motor bracket 22 provides a position for the installation of the drive motor 24 through the central groove 221. The shaft of the drive motor 24 extends through the through hole 222 to the outside of the bottom of the central groove 221. The fan blade 23 is placed outside the bottom of the groove and connected to the shaft of the drive motor 24. The power supply body 12 is connected to the drive motor 24 through a power cable.

[0033] The fan housing 3 includes a first housing 31 and a second housing 32, which are respectively installed on the top and bottom of the fan frame 2 through housing holes 28;

[0034] The outer cover 31 and the outer cover 32 are strip-shaped hollow structures. By being installed on the outside of the fan, they serve a protective function without affecting the use of the fan.

[0035] The working principle is as follows: First, the fireplace fan is assembled by the fireplace fan base 1, fan frame 2, and fan cover 3. After assembly, the power supply 12 is connected to the drive motor 24. After the drive motor 24 is powered on, it converts electrical energy into kinetic energy, which drives the fan blades 23 to rotate at high speed, so that the fireplace fan can be used. Since the fan frame 2 in the fireplace fan can rotate 180 degrees within the base body 13, the air supply range is expanded. At the same time, the mechanical structure is simplified and the stability is improved, so that the fireplace fan has a better performance and good development prospects.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
