[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0041] Combination Figure 1-2 As shown, the embodiment of the present disclosure provides a fan assembly, including: a blade body 100. One or more blade bodies 100 are provided, and each blade body 100 is provided with connection surfaces 101 at both ends along its axial direction. When multiple blade bodies 100 are provided, adjacent blade bodies 100 are connected by connection surfaces 101, so that multiple blade bodies 100 form an integral structure; wherein, when multiple blade bodies 100 are assembled with a driving device 200, the connection surface 101 of the blade body 100 facing the driving device 200 among the multiple blade bodies 100 is provided with an axial hole 102, and the output end of the driving device 200 is connected to the axial hole 102, and the connection surface 101 of the blade body 100 facing away from the driving device 200 among the multiple blade bodies 100 is provided with a mounting shaft 300, and the multiple blade bodies 100 are assembled by the mounting shaft 300.

[0042] By using the fan assembly provided by the embodiment of the present disclosure, when there are multiple blade bodies 100, adjacent blade bodies 100 can be connected by connecting surfaces 101, so that the multiple blade bodies 100 form an integral structure, and the connection stability is high, which reduces the amplitude of the vibration when the blade body 100 is driven, and there is no need to connect multiple blade bodies 100 in series through an extension shaft, thereby improving assembly efficiency and reducing production costs. The connecting surface 101 of the blade body 100 facing the drive device 200 among the multiple blade bodies 100 is provided with an axial hole 102, and the output end of the drive device 200 is connected to the axial hole 102, which also saves the use of a coupling and further reduces production costs.

[0043] It can be understood that, in the case where the fan blade body 100 is provided with one, an axis hole 102 is provided at one end of the fan blade body 100 , and a mounting axis 300 is provided at the other end of the fan blade body 100 .

[0044] Specifically, three blade bodies 100 are provided. In this way, when three blade bodies 100 are provided, adjacent blade bodies 100 are connected by connecting surfaces 101, so that the three blade bodies 100 form an integral structure, and the connection stability is high, which reduces the amplitude of the vibration when the blade body 100 is driven, and there is no need to connect the three blade bodies 100 in series through an extension shaft, thereby improving assembly efficiency and reducing production costs. Among the three blade bodies 100, the connecting surface 101 of the blade body 100 facing the driving device 200 is provided with an axial hole 102, and the output end of the driving device 200 is connected to the axial hole 102, which also saves the use of a coupling and further reduces production costs.

[0045] Combination Figure 3 As shown, optionally, the fan body 100 includes: an impeller 110 and a connecting tube 120. The connecting tube 120 is arranged along the axis of the impeller 110 and penetrates the impeller 110, and both ends of the connecting tube 120 have connecting surfaces 101. In this way, the connecting surfaces 101 between two adjacent connecting tubes 120 are connected, and the length of the connecting tube 120 is relatively long, which can increase the spacing between the impellers 110, so that the spacing between the impellers 110 is arranged more reasonably. There is no need to set an extension shaft to connect multiple impellers 110 in series, which improves assembly efficiency and reduces production costs.

[0046] Optionally, along the axial direction of the impeller 110, the length of the connecting tube 120 is greater than or equal to the length of the impeller 110, and less than or equal to 3 times the length of the impeller 110. In this way, when the length of the connecting tube 120 is less than the length of the impeller 110, the length of the connecting tube 120 is too short, and adjacent connecting tubes 120 are connected together, so that interference occurs between adjacent impellers 110. When the length of the connecting tube 120 is greater than 3 times the length of the impeller 110, the length of the connecting tube 120 is too long, and adjacent connecting tubes 120 are connected together, so that the spacing between adjacent impellers 110 is too large, and when assembled in an air conditioner, it will take up too much space. It can be seen that the range in which the length of the connecting tube 120 is greater than or equal to the length of the impeller 110 and less than or equal to 3 times the length of the impeller 110 is more reasonable, and adjacent connecting tubes 120 are connected together, and no interference occurs between adjacent impellers 110, and the spacing between adjacent impellers 110 is also relatively small, reducing the space occupied by assembly in an air conditioner.

[0047] Specifically, along the axial direction of the impeller 110, the length of the connecting tube 120 is equal to 1.5 times the length of the impeller 110. In this way, adjacent connecting tubes 120 are connected together, adjacent impellers 110 will not interfere with each other, and the spacing between adjacent impellers 110 is relatively small, thereby reducing the space occupied by the air conditioner.

[0048] Combination Figure 4 As shown, optionally, along the axial direction of the impeller 110, a connecting plate 130 is provided in the middle of the impeller 110, and the connecting cylinder 120 is arranged through the connecting plate 130, and the connecting cylinder 120 is connected to the impeller 110 through the connecting plate 130. In this way, the connecting cylinder 120 is connected to the impeller 110 through the connecting plate 130, and the connection stability is higher. The connecting plate 130 is arranged in the middle of the impeller 110, so that the length of the impeller 110 distributed on both sides of the connecting plate 130 is more uniform. When the impeller 110 rotates to convey the airflow, the amount of air conveyed on both sides of the connecting plate 130 is more uniform, reducing the risk of the connecting plate 130 deflecting, thereby reducing the risk of the impeller 110 jumping.

[0049] Specifically, the connecting plate 130 is fixedly connected to the impeller 110 .

[0050] Optionally, the impeller 110 includes: a first blade 111 and a second blade 112. A plurality of first blades 111 are provided, and the plurality of first blades 111 are arranged on one side of the connecting plate 130; a plurality of second blades 112 are provided, and the plurality of second blades 112 are arranged on the other side of the connecting plate 130; wherein the plurality of first blades 111 and the plurality of second blades 112 are arranged alternately. In this way, when the first blades 111 and the second blades 112 are rotated to convey the airflow, since the plurality of first blades 111 and the plurality of second blades 112 are arranged alternately, the interval between the airflow delivered by the first blades 111 and the airflow delivered by the second blades 112 is shorter, and the air supply is more uniform.

[0051] Optionally, the diameter of the connecting tube 120 is greater than or equal to 30% of the diameter of the impeller 110, and less than or equal to 40% of the diameter of the impeller 110. In this way, when the diameter of the connecting tube 120 is less than 30% of the diameter of the impeller 110, the diameter of the connecting tube 120 is too small, the strength of the connecting tube 120 is low, and the risk of beating when the impeller 110 rotates is greater. When the diameter of the connecting tube 120 is greater than 40% of the diameter of the impeller 110, the diameter of the connecting tube 120 is too large, and when the impeller 110 rotates to supply air, the space occupied by the connecting tube 120 is large, which will reduce the air supply of the impeller 110. It can be seen that the range of the diameter of the connecting tube 120 being greater than or equal to 30% of the diameter of the impeller 110 and less than or equal to 40% of the diameter of the impeller 110 is more reasonable, the strength of the connecting tube 120 is relatively high, the risk of beating when the impeller 110 rotates is reduced, and it will not occupy too much space, thereby increasing the air supply of the impeller 110.

[0052] Specifically, the diameter of the connecting tube 120 is equal to 35% of the diameter of the impeller 110. In this way, the strength of the connecting tube 120 is relatively high, reducing the risk of vibration when the impeller 110 rotates, and will not occupy too much space, thereby increasing the air supply of the impeller 110.

[0053] Optionally, the connecting cylinder 120 is made of plastic. In this way, the connecting cylinder 120 made of plastic is lighter, which reduces the weight of the fan assembly as a whole.

[0054] Optionally, a reinforcing member 140 is provided in the connecting cylinder 120, and the reinforcing member 140 is fixedly connected to the inner wall of the connecting cylinder 120. In this way, by providing the reinforcing member 140 in the connecting cylinder 120, the strength of the connecting cylinder 120 is improved, and the risk of the impeller 110 jumping during the rotation of the impeller 110 and the connecting cylinder 120 is reduced.

[0055] Optionally, the reinforcing member 140 extends upward along the axis of the connecting tube 120, and both ends of the reinforcing member 140 are retracted into the two connecting surfaces 101 corresponding to the connecting tube 120. In this way, when two adjacent connecting tubes 120 are connected together, since both ends of the reinforcing member 140 are retracted into the two connecting surfaces 101 corresponding to the connecting tube 120, the reinforcing members 140 in the two connecting tubes 120 will not interfere with each other.

[0056] Optionally, the reinforcing member 140 is a reinforcing plate 141. In this way, when two adjacent connecting tubes 120 are connected together, since both ends of the reinforcing plate 141 are retracted into the two connecting surfaces 101 corresponding to the connecting tubes 120, the reinforcing plates 141 in the two connecting tubes 120 will not interfere with each other.

[0057] Optionally, the cross section of the reinforcing plate 141 is cross-shaped. In this way, the strength of the reinforcing plate 141 is relatively high, thereby providing support for the connecting cylinder 120 and reducing the risk of the impeller 110 jumping during the rotation of the impeller 110 and the connecting cylinder 120.

[0058] Optionally, the reinforcing plate 141 is made of plastic. In this way, the reinforcing plate 141 made of plastic is relatively light, which reduces the weight of the fan assembly as a whole.

[0059] Optionally, the impeller 110 is made of plastic. In this way, the impeller 110 made of plastic is relatively light, which reduces the weight of the fan assembly as a whole.

[0060] Combination Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, optionally, a volute 400 is provided on the outside of each blade body 100. In this way, through the cooperation between the blade body 100 and the volute 400, the blade body 100 rotates to suck air from both sides of the volute 400, and then sends the air out from one side of the volute 400. In addition, the wind pressure inside the volute 400 is relatively large, which increases the distance of air delivery.

[0061] It can be understood that since the multiple first fan blades 111 and the multiple second fan blades 112 are staggered, there is a time difference between the airflow delivered by the first fan blades 111 and the airflow delivered by the second fan blades 112, so that the airflow delivered by the first fan blades 111 and the airflow delivered by the second fan blades 112 are alternately blown toward the volute tongue of the volute 400, thereby reducing the noise generated by the collision between the airflow and the volute tongue.

[0062] Optionally, the volute 400 includes: a first shell 410 and a second shell 420. The first shell 410 and the second shell 420 are detachably connected. In this way, the first shell 410 and the second shell 420 are detachably connected, and the first shell 410 and the second shell 420 are disassembled and separated, and then the fan body 100 is assembled in the first shell 410 and the second shell 420, which reduces the difficulty of assembly.

[0063] Optionally, a connecting buckle 430 is provided on the first housing 410, and a plug-in connector 440 is provided on the second housing 420, wherein the plug-in connector 440 is engaged with the connecting buckle 430. Thus, when the first housing 410 and the second housing 420 are assembled together, the plug-in connector 440 passes through the connecting buckle 430 and is engaged with the connecting buckle 430, thereby improving assembly efficiency.

[0064] Optionally, the plug-in component 440 includes: a plug-in board 441 and a limiting plate 442. The plug-in board 441 is fixedly connected to the outer side wall of the second housing 420; the limiting plate 442 is fixedly connected to the plug-in board 441, and the limiting plate 442 is arranged between the plug-in board 441 and the second housing 420. In this way, when the first housing 410 and the second housing 420 are installed together, the plug-in board 441 passes through the connecting buckle 430 and is clamped therewith, and the limiting plate 442 abuts against the outer side wall of the first housing 410 to reduce the relative shaking between the first housing 410 and the second housing 420.

[0065] Optionally, the first shell 410 is provided with a first guard plate, which is fixedly connected to the outer side wall of the first shell 410 and extends toward the second shell 420; the second shell 420 is provided with a second guard plate, which is fixedly connected to the outer side wall of the second shell 420 and extends toward the first shell 410. In this way, when the first shell 410 and the second shell 420 are assembled together, the first guard plate extends toward the second shell 420, the first guard plate abuts against the second shell 420, and the second guard plate extends toward the first shell 410 and abuts against the first shell 410, thereby reducing the risk of relative shaking between the first shell 410 and the second shell 420.

[0066] Specifically, two first guard plates are provided, and the two first guard plates are provided on both sides of the second guard plate. In this way, by providing two first guard plates, when the first shell 410 and the second shell 420 are assembled together, the two first guard plates extend toward the second shell 420, and the two first guard plates abut against the second shell 420, further reducing the risk of relative shaking between the first shell 410 and the second shell 420.

[0067] Specifically, three volutes 400 are provided. Thus, the number of volutes 400 corresponds to the number of blade bodies 100, and each blade body 100 is matched with a corresponding volute 400. The blade body 100 rotates to inhale airflow from both sides of the volute 400, and then sends the airflow out from one side of the volute 400. The wind pressure inside the volute 400 is relatively large, which increases the distance of air delivery.

[0068] Optionally, the connection surfaces 101 are welded together by ultrasonic wave, so that the welding speed is relatively fast and the welding strength is relatively high.

[0069] It can be understood that, in the case where a plurality of fan blade bodies 100 are provided, two adjacent fan blade bodies 100 are welded together via two adjacent connecting surfaces 101 , and the connecting surfaces 101 are welded together via an ultrasonic welding process.

[0070] Specifically, the driving device 200 is a driving motor 210, and the output shaft of the driving motor 210 is connected to the shaft hole 102. In this way, the driving motor 210 drives the fan body 100 to rotate by cooperating with the shaft hole 102.

[0071] Combination Fig. 9 As shown, in some embodiments, the air conditioner includes: a fan assembly as described in the above embodiments.

[0072] The air conditioner provided by this embodiment includes the fan assembly of the above-mentioned embodiment. When there are multiple blade bodies 100, adjacent blade bodies 100 can be connected by connecting surfaces 101, so that multiple blade bodies 100 form an integral structure. The connection stability is high, which reduces the amplitude of the vibration when the blade body 100 is driven. There is no need to connect multiple blade bodies 100 in series through an extension shaft, which improves assembly efficiency and reduces production costs. The connecting surface 101 of the blade body 100 facing the drive device 200 among the multiple blade bodies 100 is provided with an axial hole 102, and the output end of the drive device 200 is connected to the axial hole 102, which also saves the use of a coupling and further reduces production costs.

[0073] Optionally, the air conditioner further comprises: an air conditioner body 500. The air conditioner body 500 is provided with a mounting portion 510 for mounting a fan assembly. Thus, the fan assembly is assembled in the mounting portion 510, which improves the assembly efficiency of the air conditioner body 500 and reduces the production cost.

[0074] Optionally, the air conditioner further includes a bearing seat 520. The bearing seat 520 is disposed in the mounting portion 510, sleeved on the outside of the mounting shaft 300, and rotatably connected to the mounting shaft 300. In this way, the bearing seat 520 is connected to the mounting shaft 300 to improve the stability of the connection and reduce the rotation resistance of the mounting shaft 300.
