Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to an anti-electric shaft assembly and an air conditioner. Background Technology

[0002] In current air conditioning products, the air guide vane is usually driven by a motor. The fit between the motor shaft and the mounting hole of the air guide vane is usually not an interference fit to facilitate the connection between the motor shaft and the air guide vane. However, due to errors in the production of the motor shaft and assembly errors, the clearance between the motor shaft and the mounting hole is too large, which can easily lead to lag in the driving of the air guide vane. This can cause problems such as shaking, jamming, or abnormal noise during the rotation of the air guide vane, which is not conducive to reliable transmission between the motor shaft and the air guide vane. Utility Model Content

[0003] The main purpose of this utility model is to propose an anti-electric shaft assembly and an air conditioner, which aims to improve the transmission reliability between the anti-electric shaft assembly and the driven structure.

[0004] To achieve the above objectives, the present invention provides an anti-electric shaft assembly comprising:

[0005] An anti-electric shaft has an output body for connecting a structure to be driven, the output body being provided with a slot; and

[0006] An elastic support is embedded in the slot.

[0007] In one embodiment, the slot includes a main slot and a limiting guide slot. The main slot extends along the axial direction of the output body, and one end of the limiting guide slot is laterally connected to the main slot, while the other end penetrates the side wall of the output body.

[0008] The elastic support includes a support body adapted to the main groove and a limiting guide body adapted to the limiting guide groove.

[0009] In one embodiment, the main slot is located in the central region of the output main body;

[0010] And / or, the support body is interference-fitted into the main body groove;

[0011] And / or, the ratio of the depth of the main body groove to the length of the output main body is k, where k ≥ 2 / 3.

[0012] In one embodiment, the depth of the limiting guide groove is equal to the depth of the main body groove;

[0013] And / or, the limiting guide body is interference-fitted into the limiting guide groove;

[0014] And / or, the width of the limiting guide groove is smaller than the width of the main body groove;

[0015] And / or, a guide ramp is provided between the anti-electric shaft and / or the elastic support.

[0016] In one embodiment, the sidewall of the output body has multiple planes connected end to end, and the planes are provided with the limiting guide grooves. The opening size of the limiting guide grooves is a, and the size of the planes is b, where 2a≤b.

[0017] In one embodiment, two limiting guide grooves are provided, and the two limiting guide grooves can be selectively provided on any two of the planes.

[0018] In one embodiment, the slot further includes a guide groove, which is located on the side of the main slot away from the structure to be driven and extends through the anti-electric shaft. The elastic support also includes a guide body extending into the guide groove.

[0019] In one embodiment, the radial dimension of the guide body is smaller than the radial dimension of the support body.

[0020] In one embodiment, the radial dimension of the guide body is gradually reduced in the direction away from the support body;

[0021] And / or, the guide body and the groove wall of the guide mating groove are spaced apart.

[0022] This utility model also proposes an air conditioner that includes the anti-electric shaft assembly as described above.

[0023] In one embodiment, the air conditioner includes an air guide plate assembly and a drive assembly, and the anti-electric shaft includes an input body and an output body connected together. The input body is drivenly connected to the drive assembly, and the output body is fixedly connected to the air guide plate assembly.

[0024] In one embodiment, the air guide plate assembly includes an air guide plate, the air guide plate having a shaft hole for the output body to be inserted into;

[0025] Alternatively, the air guide plate assembly includes an air guide plate and a pin, the air guide plate having a mounting hole, the pin having a mounting portion that fits into the mounting hole, and the mounting portion having a shaft hole for the output body to be inserted into.

[0026] In the technical solution of this utility model, the output body of the anti-electric shaft has a slot, and an elastic support is embedded in the slot. The slot improves the ability of the output body to deform and generate reverse rebound force. When the output body is assembled into the shaft hole of the structure to be driven, the output body is compressed and enters the shaft hole due to the slot. After assembly, the output body provides a reverse rebound force to the structure to be driven, ensuring a tight fit between the output body and the structure to be driven, reducing problems such as vibration, jamming, or abnormal noise caused by drive lag, and improving the transmission reliability between the anti-electric shaft assembly and the structure to be driven. Furthermore, because the elastic support is embedded in the slot, compared with an anti-electric shaft without an embedded elastic support, the elastic support can provide continuous support to the slot without affecting the assembly of the output body into the shaft hole, ensuring that the output body can provide a continuous reverse rebound force to the structure to be driven, achieving a zero-clearance fit between the output body and the structure to be driven, further improving the transmission reliability between the anti-electric shaft assembly and the structure to be driven, while reducing the possibility of anti-electric shaft failure and extending the service life of the anti-electric shaft.

[0027] Furthermore, because the anti-electric shaft assembly is set up relatively independently from other components, it can support independent disassembly and assembly, improving the ease of disassembly and assembly. At the same time, it improves the maintenance convenience of products using the anti-electric shaft assembly. In addition, when the anti-electric shaft assembly fails, after-sales issues can be resolved by replacing it with a new one. Moreover, the replacement cost is low, the disassembly and assembly are highly convenient, and users can operate it themselves. Attached Figure Description

[0044] In current air conditioning products, the air guide vane is usually driven by a motor. The fit between the motor shaft and the mounting hole of the air guide vane is usually not an interference fit to facilitate the connection between the motor shaft and the air guide vane. However, due to errors in the production of the motor shaft and assembly errors, the clearance between the motor shaft and the mounting hole is too large, which can easily lead to lag in the driving of the air guide vane. This can cause problems such as shaking, jamming, or abnormal noise during the rotation of the air guide vane, which is not conducive to reliable transmission between the motor shaft and the air guide vane.

[0045] To address the aforementioned issues, existing technologies, such as the common application of grease, utilize the viscosity and lubricating isolation properties of grease to improve phenomena such as jamming or abnormal noise. However, grease exposed to air is prone to evaporation or deterioration during long-term use, leading to the recurrence of problems such as jamming or abnormal noise.

[0046] To solve this technical problem, this utility model proposes an anti-electric shaft assembly.

[0047] Please see Figures 1 to 7 In one embodiment of this utility model, the anti-electric shaft assembly includes an anti-electric shaft 10 and an elastic support member 20. The anti-electric shaft 10 has an output body 11 for connecting to the structure to be driven, and the output body 11 is provided with a slot 111. The elastic support member 20 is embedded in the slot 111. This can not only extend the service life of the elastic support member 20, but also make the anti-electric shaft assembly and the structure to be driven fit tightly together, thereby improving the transmission reliability between the anti-electric shaft assembly and the structure to be driven.

[0048] In the technical solution of this utility model, the output body 11 of the anti-electric shaft 10 has a slot 111, and an elastic support member 20 is embedded in the slot 111. The slot 111 can improve the ability of the output body 11 to deform and generate reverse rebound force. When the output body 11 is assembled into the shaft hole 31 of the structure to be driven, the output body 11 is compressed and enters the shaft hole 31 due to the slot 111. After being assembled in place, the output body 11 provides a reverse rebound force to the structure to be driven, ensuring a tight fit between the output body 11 and the structure to be driven, and reducing vibration, jamming or abnormal noise caused by drive lag. The problem is that the transmission reliability between the anti-electric shaft assembly and the driven structure is improved; and, because the elastic support 20 is embedded in the slot 111, compared with the anti-electric shaft 10 without the elastic support 20 embedded, the elastic support 20 can provide continuous support to the slot 111 without affecting the assembly of the output body 11 to the shaft hole 31, ensuring that the output body 11 can provide continuous reverse elastic force to the driven structure, realizing zero clearance fit between the output body 11 and the driven structure, further improving the transmission reliability between the anti-electric shaft assembly and the driven structure, while reducing the possibility of failure of the anti-electric shaft 10 and extending the service life of the anti-electric shaft 10.

[0049] Furthermore, because the anti-electric shaft assembly is set up relatively independently from other components, it can support independent disassembly and assembly, improving the ease of disassembly and assembly. At the same time, it improves the maintenance convenience of products using the anti-electric shaft assembly. In addition, when the anti-electric shaft assembly fails, after-sales issues can be resolved by replacing it with a new one. Moreover, the replacement cost is low, the disassembly and assembly are highly convenient, and users can operate it themselves.

[0050] It should be noted that, due to the design of the slot 111, the surface of the output body 11 will have an opening 1114 communicating with the slot 111 to cut the output body 11, providing deformation space to improve the deformability of the output body 11. The design of the elastic support 20 can effectively prevent the output body 11 from losing its elasticity due to constant pressure, thereby reducing the risk of failure of the anti-electric shaft 10. The specific material of the elastic support 20 includes, but is not limited to, rubber and silicone. The elastic support 20 is embedded in the slot 111, that is, the elastic support 20 does not protrude from the end face and / or side of the output body 11. However, because there is a large contact area between the elastic support 20 and the slot wall of the slot 111, the elastic support 20 can still provide continuous support to the output body 11, which can not only allow the output body 11 to be fully inserted into the shaft hole 31 of the structure to be driven, but also ensure the tight fit between the output body 11 and the structure to be driven.

[0051] The structure to be driven can be the air guide plate assembly of an air conditioner, which can be driven to rotate by the anti-electric shaft assembly. It can also be other structures that rotate. By connecting the anti-electric shaft assembly with the structure to be driven, it can be effectively prevented that the structure to be driven cannot follow the movement of the anti-electric shaft assembly in time to turn, thereby reducing the possibility of vibration, jamming or abnormal noise caused by drive lag.

[0052] Please see Figure 1 and Figure 3 In an embodiment of this utility model, the slot 111 includes a main slot 1111 and a limiting guide slot 1112. The main slot 1111 extends along the axial direction of the output body 11. One end of the limiting guide slot 1112 is laterally connected to the main slot 1111, and the other end penetrates the side wall of the output body 11. It can be understood that by opening the limiting guide slot 1112 on the side wall of the output body 11, a space for deformation of other structures is formed on the side wall of the output body 11. The main slot 1111 is also opened on the end face of the output body 11, and the main slot 1111 is connected to the limiting guide slot 1112. While ensuring the driving reliability of the anti-electric shaft assembly for the driven structure, it can increase the space for deformation of other structures on the output body 11, improve the reliability of the output body 11 being inserted into the shaft hole 31, and increase the effective connection area between the output body 11 and the elastic support member 20, thereby improving the support effect of the elastic support member 20 on the slot 111. Of course, in other embodiments, the slot 111 may only include the main slot 1111 or the limiting guide slot 1112.

[0053] The limiting guide groove 1112 and the main body groove 1111 can be arranged side by side in one direction of the output body 11. This direction can pass through the axis of the output body 11 or be parallel to the radial direction of the output body 11. On the radial section of the output body 11, the cross-sectional shape of the limiting guide groove 1112 is different from that of the main body groove 1111, and / or the cross-sectional dimensions of the limiting guide groove 1112 are different from those of the main body groove 1111. This can, to a certain extent, correct the assembly angle of the elastic support 20, improve the assembly efficiency of the elastic support 20, and enhance the connection strength between the elastic support 20 and the output body 11.

[0054] The elastic support member 20 includes a support body 21 adapted to the main body groove 1111 and a limiting guide body 22 adapted to the limiting guide groove 1112. That is, the support body 21 is embedded in the main body groove 1111 and supported by the groove wall of the main body groove 1111, and the limiting guide body 22 is embedded in the limiting guide groove 1112 and supported by the groove wall of the limiting guide groove 1112. This ensures that the elastic support member 20 provides continuous support to the groove 111 under long-term use, thereby achieving zero-clearance fit between the output body 11 and the structure to be driven, improving the transmission reliability between the anti-electric shaft assembly and the structure to be driven, and reducing the possibility of failure of the anti-electric shaft 10, thus extending the service life of the anti-electric shaft 10.

[0055] Specifically, in the embodiments of this utility model, the main body groove 1111 is located in the central region of the output body 11; that is, the main body groove 1111 extends along the axial direction of the output body 11 and is located at the center of the output body 11, and / or is radially symmetrically arranged about the output body 11. This can increase the deformability of the output body 11, and when multiple limiting guide grooves 1112 are provided, the distance from the opening 1114 of each limiting guide groove 1112 to the main body groove 1111 is equal, which can evenly divide the output body 11. Therefore, when the shaft hole 31 is inserted and assembled in place, the output body 11 is subjected to uniform force and deformation at all positions, which can extend the service life of the output body 11 to a certain extent. The cross-sectional shape of the main body groove 1111 includes, but is not limited to, circular, square, and annular shapes. In this case, the cross-sectional shape of the supporting body 21 is adapted to the cross-sectional shape of the main body groove 1111.

[0056] Please see Figure 2 In this embodiment of the present invention, the support body 21 is interference-fitted into the main body groove 1111. Thus, while ensuring that the interference does not prevent the elastic support 20 from being unable to be assembled into the output body 11, i.e., the output body 11 can be reliably compressed, the support body 21 provides continuous support to the groove wall of the main body groove 1111, so that the output body 11 and the hole wall of the shaft hole 31 are in zero-gap contact. This prevents the rotation output of the electric shaft assembly from being transmitted to the structure to be driven in a timely manner, and reliably reduces the possibility of vibration, jamming or abnormal noise caused by drive lag.

[0057] Optionally, in an embodiment of this utility model, the ratio of the depth of the main body groove 1111 to the length of the output body 11 is k, where k ≥ 2 / 3. It can be understood that the length of the output body 11 is its axial length, which is also the mating length between the anti-electric shaft 10 and the structure to be driven. By limiting k ≥ 2 / 3, that is, the depth of the main body groove 1111 is at least 2 / 3 of the mating length of the anti-electric shaft 10, reliable deformation of the anti-electric shaft 10 is ensured. Simultaneously, a larger connection area is guaranteed between the support body 21 and the main body groove 1111, thereby increasing the length of zero-gap contact between the output body 11 and the hole wall of the shaft hole 31, reducing the possibility of jamming or abnormal noise. Furthermore, because the elastic support member 20 does not protrude from the end face of the output body 11, the ratio of the length of the support body 21 to the depth of the main body groove 1111 is less than or equal to 1.

[0058] Please see Figure 1 and Figure 5 In this embodiment of the present invention, the depth of the limiting guide groove 1112 is equal to the depth of the main body groove 1111. That is, in the axial direction of the output body 11, the depth of the limiting guide groove 1112 is equal to the depth of the main body groove 1111. In other words, the ratio of the depth of the limiting guide groove 1112 to the length of the output body 11 is k', where k' = k ≥ 2 / 3. This ensures reliable deformation of the anti-electric shaft 10 and also guarantees a large connection area between the limiting guide body 22 and the limiting guide groove 1112, thereby increasing the length of zero-gap contact between the output body 11 and the hole wall of the shaft hole 31, reducing the possibility of jamming or abnormal noise. Furthermore, because the elastic support member 20 does not protrude from the end face of the output body 11, the ratio of the length of the support body 21 to the depth of the main body groove 1111 is less than or equal to 1.

[0059] Furthermore, in the embodiments of this utility model, the width of the limiting guide groove 1112 is smaller than the width of the main body groove 1111. It can be understood that on the radial cross-section of the output body 11, the limiting guide groove 1112 connects to the main body groove 1111, and a stepped structure is formed at their connection point. This can, to a certain extent, correct the assembly angle of the elastic support member 20. That is, based on the position of the limiting guide groove 1112, the limiting guide body 22 can be rotated to align with the limiting guide groove 1112, improving the assembly efficiency of the elastic support member 20. It can also increase the connection area between the elastic support member 20 and the output body 11, enhancing the connection strength between the elastic support member 20 and the output body 11. When the cross-sectional shape of the main body groove 1111 is circular, the width of the main body groove 1111 is specifically the diameter of the main body groove 1111; the width of the limiting guide groove 1112 is specifically the width of the opening 1114 of the limiting guide groove 1112.

[0060] Please see Figure 2In this embodiment of the present invention, the limiting guide body 22 is interference-fitted into the limiting guide groove 1112. Thus, while ensuring that the interference does not prevent the elastic support 20 from being unable to be assembled into the output body 11, i.e., the output body 11 can be reliably compressed, the limiting guide body 22 provides continuous support to the groove wall of the limiting guide groove 1112, so that the output body 11 and the hole wall of the shaft hole 31 are in zero-gap contact. This prevents the rotation output of the electric shaft assembly from being transmitted to the structure to be driven in a timely manner, and reliably reduces the possibility of vibration, jamming or abnormal noise caused by drive lag.

[0061] Please see Figure 1 , Figure 3 and Figure 4 In embodiments of this utility model, a guide slope 24 is provided between the anti-electric shaft 10 and / or the elastic support 20. Specifically, the end of the support body 21 and the limiting guide body 22 facing the slot 111 forms a guide slope 24, and / or the edge of the slot 111 facing the groove of the elastic support 20 forms a guide slope 24. Thus, the assembly efficiency of the elastic support 20 can be improved by the guiding effect of the guide slope 24. Of course, in other embodiments, the support body 21 is tapered as a whole, and its outer wall surface forms the guide slope 24, which can also improve the assembly efficiency of the elastic support 20 to a certain extent.

[0062] Optionally, in an embodiment of this utility model, the sidewall of the output body 11 has multiple planes connected end to end, and the planes are provided with the limiting guide groove 1112. The opening 1114 of the limiting guide groove 1112 has a size of a, and the size of the plane is b, 2a≤b. It can be understood that when the output body 11 has an n-angle structure with n planes, at least one plane is provided with the limiting guide groove 1112, and the limiting guide groove 1112 is connected to the main body groove 1111; Figure 2 As shown, by limiting the width of the opening 1114 of the limiting guide groove 1112 to no more than half the width of one side of the plane, a deformation gap can be provided to achieve the deformation purpose of the output body 11, while also ensuring the structural strength and rigidity of the output body 11 and reducing the risk of failure of the output body 11. One plane corresponds to one limiting guide groove 1112. Of course, in other embodiments, multiple limiting guide grooves 1112 are provided on one plane, as long as the total width of the opening 1114 does not exceed half the width of one side of the plane.

[0063] Furthermore, in the embodiments of this utility model, two limiting guide grooves 1112 are provided. The two limiting guide grooves 1112 can be selectively provided on any two planes. Both limiting guide grooves 1112 are connected to the main groove 1111, and the two planes where the two limiting guide grooves 1112 are located can be arranged adjacently, opposite to each other, or not adjacent and intersecting.

[0064] Please see Figure 1 and Figure 3 In an embodiment of this utility model, the slot 111 further includes a guide mating groove 1113. The guide mating groove 1113 is located on the side of the main body slot 1111 away from the structure to be driven and passes through the anti-electric shaft 10. The elastic support member 20 also includes a guide body 23 extending into the guide mating groove 1113. It can be understood that after the guide body 23 plays the role of initial positioning and assembly guidance for the elastic support member 20, the guide body 23 is accommodated by the guide mating groove 1113 to avoid the guide body 23 occupying the main body slot 1111, thus affecting the interference fit between the support body 21 and the main body slot 1111, and affecting the requirement that the elastic support member 20 does not exceed the end face of the output body 11.

[0065] The anti-electric shaft 10 includes an input body 12 and an output body 11 connected to each other. The input body 12 is used to connect to the drive assembly 40 to realize the transmission of rotational power. In this case, the guide groove 1113 penetrates part of the output body 11 and the input body 12, which helps to reduce the overall weight of the anti-electric shaft assembly. Of course, in other embodiments, the guide groove 1113 can be configured as a blind groove, that is, it only penetrates the output body 11 and penetrates part of the input body 12 or does not penetrate the input body 12. Of course, in other embodiments, the guide slope 24 formed between the anti-electric shaft 10 and / or the support body 21 and the limiting guide body 22 is used to achieve the function of initial positioning and assembly guidance.

[0066] Specifically, in the embodiments of this utility model, the radial dimension of the guide body 23 is smaller than the radial dimension of the support body 21. At this time, the opening of the guide mating groove 1113 is smaller than the opening of the main groove 1111. That is, the opening of the guide mating groove 1113 is formed on the bottom wall of the main groove 1111, which facilitates the guide body 23 to find the opening of the slot 111 and guide the support body 21 to extend into the main groove 1111. The guide body 22 is limited to extend into the limiting guide groove 1112. Furthermore, when the support body 21 is assembled in place, the edge of the opening of the guide mating groove 1113 or the bottom wall of the main groove 1111 restricts the further movement of the support body 21, reducing the possibility of a small connection area between the support body 21 and the main groove 1111. This ensures the support effect of the support body 21 on the main groove 1111 and the zero-clearance fit effect between the output body 11 and the shaft hole 31. It can also reduce the amount of material used in the elastic support member 20.

[0067] Furthermore, in this embodiment of the present invention, the radial dimension of the guide body 23 gradually decreases in the direction away from the support body 21; that is, the guide body 23 is tapered in the direction away from the support body 21, forming a conical structure, which allows the outer wall surface of the guide body 23 to be inclined and constitutes a guide surface with a guiding function, which is beneficial to further improve the guiding ability of the guide body 23. The end face of the guide body 23 away from the support body 21 can be parallel to the end face of the output body 11, that is, both are perpendicular to the axis of the output body 11. Compared with the point structure of the end face of the guide body 23 away from the support body 21, this is beneficial to improve the structural stability of the guide body 23 and reduce the possibility of breakage at the end of the guide body 23.

[0068] Optionally, in an embodiment of this utility model, the guide body 23 and the guide mating groove 1113 are spaced apart, meaning the guide body 23 only serves a guiding function and does not provide support for the guide mating groove 1113 after the elastic support member 20 is assembled in place. However, in other embodiments, the guide body 23 and the guide mating groove 1113 are in a zero-clearance fit; or the guide body 23 and the guide mating groove 1113 are in an interference fit.

[0069] This utility model also proposes an air conditioner, which includes an anti-electric shaft assembly. The specific structure of the anti-electric shaft assembly is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0070] Please see Figures 5 to 7In an embodiment of this utility model, the air conditioner includes an air guide plate assembly and a drive assembly 40. The anti-electric shaft 10 includes an input body 12 and an output body 11 connected together. The input body 12 is connected to the drive assembly 40 in a transmission manner, and the output body 11 is fixedly connected to the air guide plate assembly. It can be understood that the input body 12 is used to connect to the drive assembly 40 so that after the drive assembly 40 outputs driving force, the driving force is transmitted to the anti-electric shaft 10 through the input body 12, so that the anti-electric shaft 10 has a rotational motion tendency as a whole. Since the output body 11 is fixedly connected to the air guide plate assembly, it can reliably drive the air guide plate assembly to rotate.

[0071] Among them, because the output body 11 is embedded with an elastic support 20, when the output body 11 is connected to the air guide plate assembly, the elastic support 20 always provides support to the output body 11, so as to realize the zero clearance fit between the output body 11 and the air guide plate assembly, thereby reliably reducing problems such as shaking, jamming or abnormal noise caused by drive lag, and improving the transmission reliability between the anti-electric shaft assembly and the air guide plate assembly.

[0072] More specifically, in one embodiment of this utility model, the air guide plate assembly includes an air guide plate, which has a shaft hole 31 for the output body 11 to be inserted into. The air guide plate includes an air guide portion and a connecting portion connected to one side of the air guide portion. The connecting portion has a shaft hole 31. The output body 11 with elastic support member 20 is inserted into the shaft hole 31. The interference support of the support body 21 on the main body groove 1111 and the interference support of the limiting guide body 22 on the limiting guide groove 1112 are used to ensure that the elastic support member 20 always provides support force to the output body 11 without affecting the insertion of the output body 11 into the shaft hole 31. This achieves zero clearance fit between the output body 11 and the air guide plate assembly. As a result, the driving force output by the drive assembly 40 can be transmitted to the air guide plate in a timely manner through the anti-electric shaft assembly, reliably solving the problems of shaking, jamming or abnormal noise.

[0073] In another embodiment of this utility model, the air guide plate assembly includes an air guide plate and a pin 30. The air guide plate has a mounting hole, and the pin 30 has a mounting portion 32 that fits into the mounting hole. The mounting portion 32 has a shaft hole 31 for the output body 11 to be inserted into. Figures 6 to 7As shown, the output body 11 with elastic support 20 is inserted into the shaft hole 31. With the interference support of the support body 21 on the main body groove 1111 and the interference support of the limiting guide body 22 on the limiting guide groove 1112, the elastic support 20 always provides support to the output body 11 without affecting the insertion of the output body 11 into the shaft hole 31. This achieves zero clearance fit between the output body 11 and the air guide plate assembly. As a result, the driving force output by the drive assembly 40 can be transmitted to the air guide plate in a timely manner through the anti-electric shaft assembly, reliably solving the problems of vibration, jamming or abnormal noise.

[0074] The air guide plate is provided with a stop part, the pin 30 is slidably connected to the air guide plate, and a limit part is provided. By cooperating with the stop part and the limit part, the pin 30 is reliably constrained to slide in the disassembly direction, thereby effectively reducing the risk of the pin 30 falling off the output body 11. The zero-gap cooperation between the anti-electric shaft assembly and the pin 30 can also improve the connection reliability between the anti-electric shaft assembly and the air guide plate assembly.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
