Description

Technical Field

[0001] This invention relates to the field of wind turbine technology, and more specifically, to a wind turbine and electrical equipment. Background Technology

[0002] Currently, in related technologies, wind turbines include electrical control components and a support frame. The support frame needs to be fixed to the frame of the stator assembly, and then the electrical control components are fixed to the support frame. The support frame is then used to install and position the electrical control components. However, this type of wind turbine structure requires many components for installing and positioning the electrical control components, resulting in a relatively heavy wind turbine. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] Therefore, the first aspect of the present invention provides a fan.

[0005] A second aspect of the present invention provides an electrical device.

[0006] In view of the above, a first aspect of the present invention provides a fan, including a stator assembly, an electrical control component, an air duct assembly, and a connector; the stator assembly includes a stator core and a frame, the frame being disposed outside the stator core; the electrical control component is disposed on a first side of the stator assembly in the axial direction; the air duct assembly is disposed on a side of the stator assembly away from the electrical control component; the connector passes through the electrical control component, the stator assembly, and the air duct assembly; wherein, the frame is provided with a first positioning part on the side near the electrical control component, the electrical control component is provided with a second positioning part, and the second positioning part cooperates with the first positioning part.

[0007] The fan provided by this invention includes a stator assembly, which comprises a stator core and a frame. The frame is disposed on the stator core and located on the axial side of the stator core. The fan also includes an electrical control component, which is disposed on a first axial side of the stator assembly.

[0008] The fan also includes duct assemblies and connectors. The connectors pass through the electrical control components, stator assembly, and duct assemblies, thereby connecting and fixing these components. The stator assembly is also clamped between the duct assemblies and electrical control components, thus securing it. Because the connection and fixing of the duct assemblies, stator assembly, and electrical control components can be achieved through connectors, the installation and fixing structure between these components is simplified. This reduces the number of parts required to fix these components, thereby reducing the overall weight of the fan and facilitating the lightweighting of household appliances.

[0009] Since the duct assembly, stator assembly, and electrical control components can be connected and fixed using connectors, the assembly process can be simplified when assembling the duct assembly, stator assembly, and electrical control components, thereby improving the assembly efficiency of the fan and reducing the assembly difficulty of the fan.

[0010] The first side of the frame faces the electrical control component. A first positioning part is provided on the first side of the frame, and a second positioning part is provided on the electrical control component. The first positioning part and the second positioning part cooperate to realize the positioning of the electrical control component, simplify the structure required for positioning the electrical control component, reduce the number of fan parts, and thus reduce the weight of the fan.

[0011] Positioning the electronic control components using the first and second positioning parts simplifies the structure required for positioning the electronic control components, thereby simplifying the assembly process of the fan, reducing the assembly difficulty of the fan, accelerating the assembly speed of the fan, and improving the assembly efficiency of the fan.

[0012] Furthermore, since the first and second positioning parts can position the electronic control components, the structure required for positioning the electronic control components can be simplified, thereby reducing the size of the fan. When the fan is installed on electronic equipment, it reduces the space occupied by the fan inside the electronic equipment, which is conducive to the miniaturization of the fan and thus facilitates the miniaturization design of the electronic equipment.

[0013] In addition, the fan in the above-mentioned technical solution provided by the present invention may also have the following additional technical features:

[0014] In one technical solution of the present invention, the first positioning part is a first positioning post, the second positioning part is a first positioning hole, and the first positioning post is inserted into the first positioning hole.

[0015] In this technical solution, the first positioning post is inserted into the first positioning hole, which can realize the positioning of the electronic control component, making the position of the electronic control component in the fan more accurate and improving the stability of the electronic control component during operation.

[0016] In one technical solution of the present invention, the first positioning part is a second positioning hole, the second positioning part is a second positioning post, and the second positioning post is inserted into the second positioning hole.

[0017] In this technical solution, the second positioning post is inserted into the second positioning hole, which can realize the positioning of the electronic control component, making the position of the electronic control component in the fan more accurate and improving the stability of the electronic control component during operation.

[0018] In one technical solution of the present invention, the air duct assembly includes an impeller, a shroud, and a diffuser; the shroud covers the outside of the impeller; the diffuser is connected to the shroud and is disposed between the shroud and the stator assembly.

[0019] In this technical solution, a shroud is installed outside the diffuser, forming an air duct between the shroud and the diffuser. A fan wheel is positioned between the shroud and the diffuser, driving the airflow and thus enabling air delivery via a fan.

[0020] In one technical solution of the present invention, the electronic control component is provided with a first mounting hole, the frame is provided with a second mounting hole, and the diffuser is provided with a threaded hole. The first mounting hole, the second mounting hole, and the threaded hole are axially opposite each other. The connector passes through the first mounting hole and the second mounting hole and is screwed onto the threaded hole.

[0021] In this technical solution, the connector passes through the first mounting hole provided on the electrical control component and the second mounting hole provided on the frame in sequence, and is screwed into the threaded hole provided on the diffuser, thereby fixing the air duct assembly, stator assembly and electrical control component, and improving the stability of the fan during operation.

[0022] Since the connectors pass through the first mounting hole and the second mounting hole in sequence and are tightened into the threaded hole, the air duct assembly, stator assembly and electrical control components can be fixed, which further simplifies the assembly process of the fan and reduces the assembly difficulty of the fan.

[0023] In one technical solution of the present invention, the diffuser is provided with a bearing chamber, and the fan also includes a rotor assembly, which includes a bearing assembly, a rotating shaft and a magnet assembly; the bearing assembly is embedded in the bearing chamber; the rotating shaft passes through the bearing assembly; and the magnet assembly is disposed on the rotating shaft.

[0024] In this technical solution, the bearing assembly is located in the bearing chamber of the diffuser, thereby supporting the shaft and magnet assembly and further improving the stability of the fan.

[0025] In one embodiment of the present invention, the impeller is sleeved on the rotating shaft.

[0026] In this technical solution, the impeller is mounted on the rotating shaft, and the rotor assembly can drive the impeller to rotate, thereby driving the airflow.

[0028] In this technical solution, the bearing assembly includes at least two bearings and a bushing. The at least two bearings are spaced apart within the bushing, forming a single, integrated bearing assembly that provides stable support for the rotor assembly at one end of the shaft. Since the rotor assembly is supported at one end of the shaft, no additional support for the rotor assembly is needed at the other end, further reducing the number of fan components and simplifying the fan assembly process.

[0029] In one technical solution of the present invention, the diffuser is provided with a third positioning part, and the stator core is provided with a fourth positioning part, the third positioning part and the fourth positioning part cooperating.

[0030] In this technical solution, the third positioning part and the fourth positioning part work together to achieve the positioning of the diffuser and the stator core, thereby improving the accuracy of the position between the diffuser and the stator core.

[0031] In one technical solution of the present invention, the third positioning part is a third positioning post, the fourth positioning part is a third positioning hole, and the third positioning post passes through the third positioning hole.

[0032] In this technical solution, the third positioning part is the third positioning post, and the fourth positioning part is the third positioning hole. The third positioning part is connected to the diffuser and inserted into the fourth positioning part set on the stator core. The third positioning part fixes the position between the stator core and the diffuser, realizes the circumferential positioning of the diffuser and the stator core, and improves the accuracy of the position between the diffuser and the stator core.

[0033] By setting a third positioning part to improve the accuracy of the position between the diffuser and the stator core, and by having the bearing chamber of the diffuser support the shaft, the accuracy of the position between the magnet assembly and the stator core can be improved, thereby improving the performance of the fan.

[0034] In one technical solution of the present invention, the stator core is provided with a third mounting hole along the axial direction, and the connector is located in the third mounting hole.

[0035] In this technical solution, the stator core is provided with a third mounting hole, and the connector is set in the third mounting hole, so that the connector can pass through the stator core, and the diffuser and electrical control components can be fixed under the action of the connector, avoiding interference between the stator core and the connector, and making the assembly of the fan smoother.

[0036] In one technical solution of the present invention, there are multiple first positioning parts, which are arranged circumferentially along the skeleton; the number of second positioning parts is the same as the number of first positioning parts.

[0037] In this technical solution, there are multiple first positioning parts, which are arranged circumferentially along the frame, making the position between the electronic control components and the stator assembly more accurate.

Detailed Implementation

[0052] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0053] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0054] The following reference Figures 1 to 7 Describes fans and electrical equipment according to some embodiments of the present invention.

[0055] In one embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 3 As shown, a fan is provided, including a stator assembly 100, an electrical control component 200, an air duct assembly 300, and a connector 400. The stator assembly 100 includes a stator core 110 and a frame 120, with the frame 120 disposed outside the stator core 110. The electrical control component 200 is disposed on a first side of the stator assembly 100 in the axial direction. The air duct assembly 300 is disposed on a side of the stator assembly 100 away from the electrical control component 200. The connector 400 passes through the electrical control component 200, the stator assembly 100, and the air duct assembly 300. The frame 120 has a first positioning part 130 on the side close to the electrical control component 200, and the electrical control component 200 has a second positioning part 210, which cooperates with the first positioning part 130.

[0056] In this embodiment, such as Figure 3 As shown, the fan includes a stator assembly 100, which includes a stator core 110 and a frame 120. The frame 120 is disposed on the stator core 110 and located on the axial side of the stator core 110. The fan also includes an electrical control component 200, which is disposed on the first axial side of the stator assembly 100.

[0057] like Figure 1 and Figure 3As shown, the fan also includes a duct assembly 300 and a connector 400. The connector 400 passes through the electrical control component 200, the stator assembly 100, and the duct assembly 300, thereby connecting and fixing the duct assembly 300, the stator assembly 100, and the electrical control component 200. Furthermore, the stator assembly 100 is clamped between the duct assembly 300 and the electrical control component 200, thus securing the stator assembly 100. Since the connection and fixation of the duct assembly 300, the stator assembly 100, and the electrical control component 200 can be achieved through the connector 400, the installation and fixing structure between these components is simplified. This reduces the number of parts required to fix the duct assembly 300, the stator assembly 100, and the electrical control component 200, thereby reducing the overall weight of the fan and facilitating the lightweighting of household appliances.

[0058] Since the air duct assembly 300, stator assembly 100 and electrical control component 200 can be connected and fixed through connector 400, the assembly process can be simplified when assembling the air duct assembly 300, stator assembly 100 and electrical control component 200, thereby improving the assembly efficiency of the fan and reducing the assembly difficulty of the fan.

[0059] The first side of the frame 120 faces the electronic control component 200. A first positioning part 130 is provided on the first side of the frame 120, and a second positioning part 210 is provided on the electronic control component 200. The first positioning part 130 and the second positioning part 210 cooperate to realize the positioning of the electronic control component 200, simplify the structure required for positioning the electronic control component 200, reduce the number of fan parts, and thus reduce the weight of the fan.

[0060] Since positioning the electronic control component 200 by the first positioning part 130 and the second positioning part 210 can simplify the structure required for positioning the electronic control component 200, thereby simplifying the assembly process of the fan, reducing the assembly difficulty of the fan, accelerating the assembly speed of the fan, and improving the assembly efficiency of the fan.

[0061] Furthermore, since the first positioning part 130 and the second positioning part 210 position the electronic control component 200, the structure required for positioning the electronic control component 200 can be simplified, thereby reducing the size of the fan. When the fan is installed on electronic equipment, it reduces the space occupied by the fan inside the electronic equipment, which is conducive to the miniaturization of the fan and thus facilitates the miniaturization design of the electronic equipment.

[0062] Specifically, the frame 120 is a plastic-coated frame, and there are two frames 120, which are respectively disposed on both sides of the stator core 110 in the axial direction. A first positioning part 130 is provided on the side of the stator core 110 near the electronic control component 200, and the first positioning part 130 can cooperate with the second positioning part 210 on the electronic control component 200.

[0063] The stator assembly 100 also includes a stator winding wound on a plastic-coated frame.

[0064] Specifically, the electronic control component 200 is an electronic control board.

[0065] Specifically, positioning the electronic control component 200 via the first positioning part 130 and the second positioning part 210, compared to positioning the electronic control component 200 via a bracket mounted on the electronic components, eliminates the need for a bracket inside the fan and eliminates the need to fix the bracket to the stator assembly 100 via the connecting part 126. This reduces the number of fan components and lowers the fan's weight. Eliminating the need for a bracket inside the fan also saves space required for bracket installation, further reducing the fan's size.

[0066] Positioning the electronic control component 200 by the first positioning part 130 and the second positioning part 210 reduces the axial height of the fan by more than 5 millimeters compared to positioning the electronic control component 200 by a bracket mounted on the electronic components.

[0067] Specifically, no support frame needs to be installed inside the fan, which reduces the fan's axial height.

[0068] Specifically, the fan is a high-speed fan.

[0069] Specifically, the stator core material is silicon steel sheet, SMC, or amorphous material.

[0070] This embodiment provides a fan, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0071] like Figure 1 and Figure 2 As shown, the first positioning part 130 is the first positioning post, and the second positioning part 210 is the first positioning hole, with the first positioning post inserted into the first positioning hole.

[0072] In this embodiment, the first positioning post is inserted into the first positioning hole, which can realize the positioning of the electronic control component 200, making the position of the electronic control component 200 in the fan more accurate and improving the stability of the electronic control component 200 during operation.

[0073] Furthermore, the skeleton 120 includes a skeleton body 124 and a first positioning part 130, the first positioning part 130 being a first positioning post, and the first positioning part 130 and the skeleton body 124 being an integral structure.

[0074] The first positioning hole is a through hole provided on the electronic control component 200, and the first positioning post extends along the axial direction of the electronic component and can be inserted into the first positioning hole.

[0075] The frame 120 also includes a connecting part 126, which is columnar. The first end of the connecting part 126 is connected to the frame 120, and the second end of the connecting part 126 abuts against the electronic control component 200. A first positioning post is disposed at the second end of the connecting part 126.

[0076] Since the second end of the connecting part 126 abuts against the electronic control component 200, the electronic control component 200 is positioned in the axial direction.

[0077] Specifically, the first positioning post can be a cylinder, a triangular prism, a cone, or a frustum. The shape of the first positioning hole matches the shape of the first positioning post.

[0078] Furthermore, the number of first positioning posts can be one or multiple, and the number of first positioning holes is the same as the number of first positioning posts, so that the first positioning holes can mate with the first positioning posts one by one, thereby enabling accurate positioning between the electrical control component 200 and the frame 120. The first positioning holes are distributed circumferentially along the electrical control component 200, so that the first positioning holes and first positioning posts can position the electrical control component 200 and the frame 120 without affecting the normal operation of the fan.

[0079] There are three first positioning holes, which are distributed circumferentially along the electronic control component 200. There are also three first positioning posts, whose positions correspond to the positions of the three first positioning holes. While positioning the electronic control component 200, the posts also support the component and improve its stability.

[0080] Specifically, the number of first positioning holes can be the same as the number of first positioning pins, or the number of first positioning holes can be different from the number of first positioning pins.

[0081] This embodiment provides a fan, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0082] The first positioning part 130 is the second positioning hole, and the second positioning part 210 is the second positioning post, which is inserted into the second positioning hole.

[0083] In this embodiment, the second positioning post is inserted into the second positioning hole, which can realize the positioning of the electronic control component 200, making the position of the electronic control component 200 in the fan more accurate and improving the stability of the electronic control component 200 during operation.

[0084] Furthermore, the number of second positioning holes can be one or multiple, and the number of second positioning posts is the same as the number of second positioning holes, so that the second positioning posts can mate with the second positioning holes one by one, thereby enabling accurate positioning between the electrical control component 200 and the frame 120. The second positioning posts are distributed circumferentially along the electrical control component 200, so that the second positioning posts and second positioning holes can position the electrical control component 200 and the frame 120 without affecting the normal operation of the fan.

[0085] There are three second positioning posts, which are distributed circumferentially along the electronic control component 200. There are also three second positioning holes, and the positions of the three positioning posts correspond to the positions of the three second positioning posts. While positioning the electronic control component 200, the holes also support the electronic control component 200, thereby improving its stability.

[0086] Specifically, the skeleton 120 includes a skeleton body 124 and a second positioning part 210. The second positioning part 210 is a second positioning hole, which is a through hole or a blind hole provided on the skeleton body 124.

[0087] The second positioning post is a post disposed on the electronic control component 200. The second positioning post extends along the axial direction of the electronic component and can be inserted into the second positioning hole.

[0088] Specifically, the second positioning post can be a cylinder, a triangular prism, a cone, or a frustum. The shape of the second positioning hole matches the shape of the second positioning post.

[0089] The number of second positioning holes can be the same as the number of second positioning pins, or the number of second positioning holes can be different from the number of second positioning pins.

[0090] Specifically, the second positioning post and the electronic control component 200 can be an integrated structure or a separate structure.

[0091] The second positioning pin can be pre-fixed on the electronic control component 200, or a positioning hole can be provided on the electronic control component 200. When assembling the electronic control component 200, the second positioning pin is inserted into the positioning hole and the second positioning hole on the electronic control component 200.

[0092] This embodiment provides a fan, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0093] like Figure 1 and Figure 3 As shown, the air duct assembly 300 includes an impeller 310, a shroud 320, and a diffuser 330; the shroud 320 covers the impeller 310; the diffuser 330 is connected to the shroud 320 and is disposed between the shroud 320 and the stator assembly 100.

[0094] In this embodiment, the shroud 320 is disposed outside the diffuser 330, and an air duct is formed between the shroud 320 and the diffuser 330. The impeller is disposed between the shroud 320 and the diffuser 330, and can drive the airflow to achieve air delivery by the fan.

[0095] This embodiment provides a fan, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0096] like Figure 4 As shown, the electronic control component 200 is provided with a first mounting hole 220, such as... Figure 5 As shown, the frame 120 is provided with a second mounting hole 122, such as Figure 6 As shown, the diffuser 330 is provided with a threaded hole 332, such as Figure 1 As shown, the first mounting hole 220, the second mounting hole 122 and the threaded hole 332 are axially opposite each other; the connector 400 passes through the first mounting hole 220 and the second mounting hole 122, and is screwed onto the threaded hole 332.

[0097] In this embodiment, the connector 400 passes sequentially through the first mounting hole 220 provided on the electronic control component 200 and the second mounting hole 122 provided on the frame 120, and is screwed into the threaded hole 332 provided on the diffuser 330, thereby fixing the air duct assembly 300, the stator assembly 100 and the electronic control component 200, and improving the stability of the fan during operation.

[0098] Since the connector 400 passes through the first mounting hole 220 and the second mounting hole 122 in sequence and is tightened into the threaded hole 332, the air duct assembly 300, the stator assembly 100 and the electrical control component 200 can be fixed, which further simplifies the assembly process of the fan and reduces the assembly difficulty of the fan.

[0099] Furthermore, a second mounting hole 122 is provided on the connecting portion 126 of the frame 120.

[0100] Specifically, the connector 400 is a bolt, with the head of the bolt abutting against the electrical control component 200 and the tail of the bolt tightened into the threaded hole 332 of the diffuser 330.

[0102] Specifically, a through hole can be provided on the diffuser 330, a threaded hole 332 can be provided on the electrical control component 200, and the connector 400 can be a screw. After the screw passes through the through hole provided on the diffuser 330 and the second mounting hole 122 provided on the bracket, it is tightened into the threaded hole 332 provided on the electrical control component 200.

[0103] Alternatively, a through hole can be provided on the diffuser 330, and the first mounting hole 220 on the electrical control component 200 is also a through hole. The connector 400 can be a bolt. After the bolt passes through the through hole provided on the diffuser 330, the second mounting hole 122 provided on the bracket, and the first mounting hole 220 provided on the electrical control component 200, it is fixed by a nut.

[0104] Specifically, the second positioning part 210 and the first mounting hole 220 are arranged opposite to each other on the electronic control board, and each second positioning part 210 is provided with a first mounting hole 220.

[0105] The number of second positioning parts 210 and first mounting holes 220 are equal and correspond one-to-one.

[0106] This embodiment provides a fan, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0107] like Figure 6 As shown, the diffuser 330 is provided with a bearing chamber 337, and the fan also includes a rotor assembly 500, which includes a bearing assembly 510, a rotating shaft 520 and a magnet assembly 530; the bearing assembly 510 is embedded in the bearing chamber 337; the rotating shaft 520 passes through the bearing assembly 510; and the magnet assembly 530 is disposed on the rotating shaft 520.

[0108] In this embodiment, the bearing assembly 510 is disposed in the bearing chamber 337 of the diffuser 330, thereby supporting the rotating shaft 520 and the magnet assembly 530 and further improving the stability of the fan.

The at least two bearings 512 are spaced apart within the bushing 514, forming a single, integrated bearing assembly 510. This allows for stable support of the rotor assembly 500 at one end of the shaft 520. Since the rotor assembly 500 is supported at one end of the shaft 520, no supporting components for the rotor assembly 500 are needed at the other end of the shaft 520, further reducing the number of fan components and simplifying the fan assembly process.

[0115] Furthermore, since the other end of the rotating shaft 520 does not require a component to support the rotor assembly 500, more space is reserved for the installation of the electronic control component 200, making the arrangement of the electronic control component 200 more convenient.

[0116] Furthermore, since the other end of the shaft 520 does not require a component to support the rotor assembly 500, the axial height of the fan is shortened, thereby reducing the space occupied by the fan in the axial direction.

[0117] This embodiment provides a fan, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0118] like Figure 6 and Figure 7 As shown, the diffuser 330 is provided with a third positioning part 334, and the stator core 110 is provided with a fourth positioning part 112. The third positioning part 334 and the fourth positioning part 112 cooperate with each other.

[0119] In this embodiment, the third positioning part 334 cooperates with the fourth positioning part 112 to achieve the positioning of the diffuser 330 and the stator core 110, thereby improving the accuracy of the position between the diffuser 330 and the stator core 110.

[0120] This embodiment provides a fan, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0121] like Figure 6 and Figure 7 As shown, the third positioning part 334 is the third positioning post, and the fourth positioning part 112 is the third positioning hole, with the third positioning post passing through the third positioning hole.

[0122] In this embodiment, the third positioning part 334 is a third positioning post, and the fourth positioning part 112 is a third positioning hole. The third positioning part 334 is connected to the diffuser 330 and is inserted into the fourth positioning part 112 provided on the stator core. The third positioning part 334 fixes the position between the stator core and the diffuser 330, realizes the circumferential positioning of the diffuser 330 and the stator core, and improves the accuracy of the position between the diffuser 330 and the stator core.

[0123] Since the accuracy of the position between the diffuser 330 and the stator core is improved by setting the third positioning part 334, and the bearing chamber 337 of the diffuser 330 can support the rotating shaft 520, the accuracy of the position between the magnet assembly 530 and the stator core can be improved, thereby improving the performance of the fan.

[0124] Specifically, the fourth positioning part 112 and the third positioning part 334 are coaxially coupled for coaxial, axial and circumferential positioning of the stator core and the diffuser 330.

[0125] Specifically, the third positioning part 334 is cylindrical, but it can also be prismatic or other irregularly shaped cylindrical.

[0126] Specifically, the third positioning part 334 can be a positioning pin, and the diffuser 330 is provided with a pin hole. One side of the positioning pin is inserted into the pin hole, and the other side cooperates with the fourth positioning part 112. The third positioning part 334 can also be an integral structure with the diffuser 330.

[0127] This embodiment provides a fan, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0128] like Figure 3 and Figure 7 As shown, the stator core 110 is provided with a third mounting hole 114 along the axial direction, and the connector 400 is located in the third mounting hole 114.

[0129] In this embodiment, the stator core is provided with a third mounting hole 114, and the connector 400 is disposed in the third mounting hole 114, so that the connector 400 can pass through the stator core, and the diffuser 330 and the electrical control component 200 can be fixed under the action of the connector 400, avoiding interference between the stator core and the connector 400, and making the assembly of the fan smoother.

[0130] Specifically, the number and distribution of the first mounting hole 220, the second mounting hole 122, and the third mounting hole 114 are consistent and they are arranged coaxially.

[0131] This embodiment provides a fan, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0132] like Figure 5 As shown, there are multiple first positioning parts 130, which are arranged circumferentially along the skeleton 120; the number of second positioning parts 210 is the same as the number of first positioning parts 130.

[0133] In this embodiment, there are multiple first positioning parts 130, which are arranged circumferentially along the frame 120, so that the position between the electronic control component 200 and the stator assembly 100 is more accurate.

[0134] This embodiment provides a fan, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0135] like Figure 6 As shown, the diffuser 330 also includes a diffuser body 336 and a first support portion 338. The first support portion 338 is connected to the diffuser body 336. The first end of the first support portion 338 abuts against the end of the stator assembly 100. A threaded hole 332 and a third positioning portion 334 are disposed at the first end of the first support portion 338.

[0136] In this embodiment, the diffuser 330 further includes a first support portion 338. The first end of the first support portion 338 abuts against the end of the stator assembly 100, thereby positioning the stator assembly 100 in the axial direction of the fan through the end of the first support portion 338. Since the diffuser 330 can support and position the rotating shaft 520, the relative position of the stator core and the magnet assembly 530 in the axial direction of the fan is more accurate, thereby improving the performance of the fan.

[0137] The threaded hole 332 and the third positioning part 334 are provided at the first end of the first support part 338, which facilitates the assembly of the diffuser 330, stator core and frame 120, reduces the assembly difficulty of the fan, simplifies the assembly process of the fan, and improves the assembly efficiency of the fan.

[0138] This embodiment provides a fan, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0139] like Figure 6 As shown, the diffuser 330 also includes a second support portion 339, the first end of which is connected to the first end of the first support portion 338, and the second end extends toward the frame 120. A third positioning portion 334 is disposed on the second support portion 339, thereby supporting the third positioning portion 334 and improving its strength.

[0140] Furthermore, the second support 339 is provided with a clearance portion, which is opposite to the threaded hole 332, so as to avoid interference between the second support 339 and the connector 400.

[0141] In one embodiment of the present invention, an electrical device is provided, including a fan as described in any of the above embodiments, and thus the electrical device possesses all the beneficial effects of the fan in any of the above embodiments.

[0142] The electrical equipment provided by the present invention includes the fan of any of the above embodiments, and the fan may be a high-speed fan.

[0143] The first beneficial effect of this high-speed fan is that all structural components can be fastened in place at once with a smaller number of parts using screws. Specifically, the electrical control component 200, stator assembly 100, and duct assembly 300 are fixed by the connector 400, which greatly improves space utilization and minimizes the weight of the high-speed fan.

[0144] The second beneficial effect is that it can effectively reduce the size of the whole machine. Because the number of parts is reduced to the greatest extent, the utilization rate of vertical space is greatly improved, and the overall height of the fan can be reduced by more than 5mm, thereby reducing the space occupied by the fan in the electrical equipment.

[0145] The third beneficial effect is the ease and efficiency of production and manufacturing. The smaller number of parts, through various positioning features on the parts, are used for positioning and fastening of the parts, which greatly reduces the number of production and manufacturing operations and improves production efficiency.

[0146] Electrical appliances include vacuum cleaners, floor scrubbers, or hair dryers.
