[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0044] The utility model embodiment provides a ceiling fan 10, which is applied below a central air conditioner 20. Figure 1 and Figure 2 As shown, the ceiling fan 10 includes a mounting base 100, a plurality of first blades 200 and a second blade 300. Among them, the plurality of first blades 200 are arranged around and spaced apart on the outside of the mounting base 100, and the air inlet side of the first blade 200 is located at the top of the first blade 200; the second blade 300 is arranged on the outside of the mounting base 100, and the distance between the second blade 300 and the mounting base 100 is smaller than the distance between the first blade 200 and the mounting base 100, and the air outlet side of the second blade 300 is located at the top of the second blade 300. The ceiling fan 10 of the present application can solve the problem of increased energy consumption of the central air conditioner 20 due to the change of the air circulation path in the prior art, improve air flow, and realize the central air conditioner 20 to work efficiently at a lower energy consumption.

[0045] Specifically, the distance between the second fan blade 300 and the mounting base 100 is smaller than the distance between the first fan blade 200 and the mounting base 100, so that the first fan blade 200 and the second fan blade 300 can respectively correspond to the air outlet 202 and the air inlet 201 of the central air conditioner 20 on their rotation paths, and a number of first fan blades 200 rotate under the action of the wind flow at the air outlet 202 of the central air conditioner 20. Since the air inlet side of the first fan blade 200 is located at the top of the first fan blade 200, it can disperse the delivered air; and the second fan blade 300 can rotate together with the first fan blade 200 at this time. Since the air outlet side of the second fan blade 300 is located at the top of the second fan blade 300, the second fan blade 300 can form a wind flow below the air during the rotation process and guide it upward to the air inlet of the central air conditioner 20, making it easier for the central air conditioner 20 to take in air, and then the central air conditioner 20 does not need to increase power to maintain air intake, so that energy consumption is effectively reduced. It can be seen that the present application can optimize the air circulation path, help improve air flow, make the central air conditioning 20 system work more efficiently, maintain a more uniform indoor temperature while reducing overall energy consumption, and be more energy-saving and environmentally friendly.

[0046] It should be noted that, in the rotation direction, there are multiple ways to set the relative positions of the first blades 200 and the second blades 300. In one embodiment, the second blades 300 can be set between two adjacent first blades 200.

[0047] Reference Figure 1 In another embodiment, the ceiling fan 10 further includes a plurality of fan rods 400, one end of each of the plurality of fan rods 400 is connected to the mounting seat 100, and the other end is respectively connected to a plurality of first blades 200, and the second blades 300 are mounted on the fan rods 400. In this arrangement, the fan rods 400, as a supporting point, can provide a stable installation and fixing effect for the second blades 300 and the first blades 200, ensuring that both will not shake or loosen during operation, thereby improving the stability of the entire ceiling fan 10. Secondly, both are mounted on the same fan rod, so there is no need to add additional parts for fixing the first blades 200 or the second blades 300, and the assembly of the ceiling fan 10 is more efficient and the cost is lower. It can also effectively reduce the rotation weight of the ceiling fan 10 itself, help the first blades 200 and the second blades 300 to rotate, and more effectively improve the air circulation flow.

[0048] Specifically, one end of the fan rod 400 is connected to the mounting seat 100, and the second fan blade 300 is mounted on the portion of the fan rod 400 exposed from the mounting seat 100. In addition, the fan rod 400 can be in the shape of an axis to facilitate processing and manufacturing, thereby reducing manufacturing costs.

[0049] Reference Figure 3 to Figure 4In one embodiment, the second fan blade 300 includes a fixing seat 310 and an air guide plate 320; the fixing seat 310 is clamped on the fan rod 400, and the air guide plate 320 is connected to the side of the fixing seat 310 facing away from the fan rod 400, and the air guide plate 320 is connected to the first direction (such as Figure 3 X direction) is at an angle (as shown in Figure 3 The first direction is perpendicular to the axis of the fan rod 400. With such a configuration, the fixing seat 310 enables the second fan blade 300 to be firmly connected to the fan rod 400, and the two are connected by a snap-fit ​​method, which makes installation faster. The configuration of the air guide plate 320 is conducive to forming an upward airflow from the air below during the rotation process, and guiding the airflow to the air inlet 201 to facilitate the air intake of the central air conditioner 20.

[0050] Specifically, the air guide plate 320 is extended upward toward the air inlet 201 to be adjacent to the air inlet 201 to reduce the moving path of the airflow. The angle between the air guide plate 320 and the first direction is set to be greater than or equal to 20° and less than or equal to 40°. For example, in this embodiment, the angle between the air guide plate 320 and the first direction is set to 25°.

[0051] In a more specific embodiment, a first limiting groove 311 is provided on one side of the fixing seat 310 facing the fan rod 400, and the first limiting groove 311 passes through the opposite end surface of the fixing seat 310 in the axial direction of the fan rod 400, and the fan rod 400 is clamped in the first limiting groove 311. In this way, during the installation process, the first limiting groove 311 of the fixing seat 310 can be installed on the fan rod 400 from top to bottom, which simplifies the assembly process, facilitates the assembly of operators, and improves the efficiency of assembly.

[0052] Specifically, the groove wall of the first limiting groove 311 is adapted to the shape of the fan rod 400 to improve the stability of the connection and reduce the shaking of the second fan blade 300 during the rotation process.

[0053] Further, refer to Figure 4 and Figure 5 The fixing seat 310 includes an extension body 312 and a plurality of blocks 313, and the plurality of blocks 313 are arranged at intervals in the axial direction of the fan rod 400; the extension body 312 and the plurality of blocks 313 jointly define a plurality of first limiting grooves 311. In this way, the fixing seat 310 and the fan rod 400 are fixed, and the weight of the fixing seat 310 itself can be effectively reduced, which helps the second fan blade 300 to rotate, thereby improving the drainage effect.

[0054] Specifically, the extension body 312 and the block 313 are respectively arranged on opposite sides of the fan rod 400 in the radial direction. While the extension body 312 extends along the axial direction of the fan rod 400, the extension body 312 also extends on the circumferential surface of the fan rod 400 to form a part of the groove wall of the first limiting groove 311. The other part of the groove wall of the corresponding first limiting groove 311 is formed on one side of the plurality of blocks 313 facing the extension body 312, so that the fan rod 400 can be limitedly installed between the extension body 312 and the block 313. And because the plurality of blocks 313 are arranged at intervals in the axial direction of the fan rod 400, a clearance area 314 is formed between the two blocks 313 to achieve the purpose of reducing the weight of the fixing seat 310 itself.

[0055] Preferably, in this embodiment, a plurality of air-avoiding holes are further provided on the extension body 312 to further reduce its own weight.

[0056] Reference Figure 6 In one embodiment, two protrusions 311a are provided on the groove wall of the first limiting groove 311, and the two protrusions 311a are respectively located on two opposite sides of the groove opening of the first limiting groove 311, and the distance between the two protrusions 311a is smaller than the diameter of the fan rod 400. In this way, the two protrusions 311a can firmly limit the fan rod 400 in the groove wall of the first limiting groove 311, and then the second fan blade 300 is difficult to separate from the fan rod 400, which greatly improves the safety of the ceiling fan 10.

[0057] Reference Figures 7 to 9 as well as Fig.13 In one embodiment, a plurality of mounting openings 110 are provided on the outer surface of the mounting seat 100, and the plurality of mounting openings 110 are arranged at intervals in the circumferential direction of the mounting seat 100; a plurality of fan rods 400 are respectively passed through the plurality of mounting openings 110, and the fan rod 400 includes a mounting portion 410 and a rod portion 420, the mounting portion 410 is installed at the mounting opening 110, one end of the rod portion 420 is connected to the mounting portion 410, and the other end of the rod portion 420 extends in a direction away from the center of the mounting seat 100; the ceiling fan 10 also includes a fixing ring 500, which surrounds the outer side surface and is arranged on the outer side of the mounting seat 100; wherein the fixing ring 500 is opposite to the mounting portion 410 of the fan rod 400 in the direction of the mounting opening 110, so as to limit the movement of the mounting portion 410 in a direction away from the center of the mounting seat 100.

[0058] Specifically, when the fixing ring 500 is in use, the fixing ring 500 first moves from the top of the mounting seat 100 from top to bottom to the outer side of the mounting seat 100, and the fixing ring 500 is opposite to the mounting portion 410 of the fan rod 400 in the direction of the mounting opening 110, so the fixing ring 500 can limit the movement of the mounting portion 410 in the direction away from the center of the mounting seat 100, thereby limiting the installation of the fan rod 400, thereby preventing the fan rod 400 from falling through the mounting opening 110. Compared with the prior art in which the fan blades are connected by screws, the material properties of the screws will change due to long-term use or the influence of the external environment, resulting in a decrease in their service life or endurance, and even loosening and cracking, and then the fan blades fall off the embodiment with a higher risk of falling, the utility model limits the movement range of the fan rod 400 by the fixing ring 500, thereby greatly reducing the risk of the fan blades falling. In addition, the use of the fixing ring 500 can also effectively reduce the frequency of regular inspections.

[0059] In a specific embodiment, a plurality of limiting grooves 520 are provided on one side of the fixing ring 500 facing the mounting opening 110, and the plurality of limiting grooves 520 all penetrate the end surface of the fixing ring 500, and the plurality of limiting grooves 520 correspond to the plurality of mounting openings 110 one by one, and a portion of the mounting portion 410 is mounted in the mounting seat 100, and another portion of the mounting portion 410 extends into the limiting grooves 520 through the mounting opening 110. In this way, the groove wall of the limiting groove 520 forms a block on the path of the mounting portion 410 toward the mounting opening 110 and away from the center of the mounting seat 100, and on both sides of the mounting portion 410, that is, when the fan rod 400 is not firmly connected to the mounting seat 100, the groove wall of the limiting groove 520 can also abut against the mounting portion 410, limit the relative position of the mounting portion 410, and thus prevent the fan rod 400 from falling off.

[0060] It is worth mentioning that part of the mounting portion 410 of the fan rod 400 is installed in the mounting seat 100, and the other part of the mounting portion 410 extends into the limiting groove 520 through the mounting opening 110, that is, part of the mounting portion 410 of the fan rod 400 is exposed outside the mounting seat 100. Compared with the embodiment of the design in which the entire mounting portion 410 is completely arranged in the mounting seat 100 and only a fixing ring 500 is used to prevent the mounting portion 410 from falling off the mounting seat 100. Exposing part of the mounting portion 410 outside the mounting seat 100 can not only effectively reduce the size of the mounting seat 100, but also reduce the manufacturing cost, while reducing the space occupied by the mounting seat 100.

[0061] Reference Fig.10 and Fig.12In one embodiment, the fixing ring 500 and the second blade 300 are integrally formed. In this way, the second blade 300 is arranged on the annular fixing ring 500, and the structural strength is better. After installation, the displacement and shaking of the second blade 300 can be effectively reduced, and the stability of the drainage effect can be ensured. In addition, the advantage of this design is that it can reduce the assembly steps and improve the assembly efficiency.

[0062] Reference Fig.13 In a specific embodiment, a second limiting groove 510 is provided on the side of the fixing ring 500 facing the rod 420, and the second limiting groove 510 penetrates the inner side and the outer side of the fixing ring 500 to communicate with the first limiting groove 311, so that the rod 420 is clamped in the first limiting groove 311 and the second limiting groove 510. In this way, when installing, when the fixing ring 500 is installed on the rod 420, it is only necessary to move the fixing ring 500 from the top of the mounting seat 100 from top to bottom to the position of the rod 420, and rotate the fixing ring 500 so that the second limiting groove 510 corresponds to a part of the outer peripheral surface of the rod 420. While aligning, the first limiting groove 311 of the second blade 300 is also aligned with the rod 420. Then, a force is applied to complete the quick installation, which shows that the assembly efficiency is further improved.

[0063] In addition, during the installation process, the fixing ring 500 is also convenient for the operator to hold with both hands, which is convenient for the operator to align the second and fan rods 400 and perform subsequent assembly.

[0064] It is worth mentioning that when the fixing ring 500 needs to be removed, it is only necessary to apply a reverse force to remove the rod 420 from the second limiting groove 510. This assembly process does not require any tools, is convenient and quick, and greatly improves the efficiency of installation and disassembly.

[0065] Reference Fig.10 and Fig.12 In a specific embodiment, the second blades 300 are provided with a plurality of them, and the plurality of second blades 300 are evenly spaced and arranged around the outer ring of the fixing ring 500 to improve the drainage effect, so that more air is formed into airflow and guided to the air inlet 201 .

[0066] Exemplarily, in this embodiment, two second blades 300 are provided, and the two second blades 300 are symmetrically arranged on both sides of the fixing ring 500 .

[0067] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
