[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0035] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0036] At present, the wind rotors on the market generally have a flat position on the shaft hole, which is matched with the flat position on the output shaft of the motor; during assembly, the output shaft of the motor passes through the through hole of the gasket and into the shaft hole, so that the flat position and the flat position are matched, so that the wind rotor and the motor are coaxial, so that when the motor is running, the wind rotor and the gasket can rotate synchronously with the output shaft of the motor. However, since the gasket blocks the flat position of the shaft hole, the operator cannot effectively identify the direction of the flat position. When installing the wind rotor on the output shaft of the motor, the flat position of the shaft hole is not easy to align with the flat position of the motor, resulting in low installation efficiency of the wind rotor.

[0037] The utility model provides a wind wheel structure.

[0038] See also Figure 1 and Figure 2 In one embodiment of the utility model, the wind wheel structure includes a wind wheel 100 and a gasket 200, the wind wheel 100 is provided with an axial hole 110 with a flat position 111; the gasket 200 is installed at one end of the axial hole 110; a flat position mark is provided on the gasket 200, or the gasket 200 and the end face of the axial hole 110 cooperate to form a flat position mark, and the flat position mark is set corresponding to the flat position 111.

[0039] The technical solution of the utility model provides a flat position mark on the gasket 200, or forms a flat position mark between the gasket 200 and the end surface of the shaft hole 110, thereby prompting the operator to the position of the obscured flat position 111. When the wind wheel 100 is installed on the motor shaft, the operator can identify the position and direction of the flat position 111 of the shaft hole 110 according to the flat position mark, so as to easily align the flat position 111 with the flat position part of the output shaft of the motor, thereby improving the assembly efficiency of the wind wheel 100.

[0040] Optionally, a marking groove 120 is provided on the end face of the axial hole 110, and a gasket 200 is provided between the marking groove 120 and the axial hole 110. The marking groove 120 is connected to the axial hole 110 through a through hole of the gasket 200. The area of ​​the gasket 200 is larger than the radial cross-sectional area of ​​the marking groove 120, and the flat position mark is formed on the groove side wall of the marking groove 120.

[0041] First, installing the gasket 200 between the marking groove 120 and the shaft hole 110 can limit the position of the gasket 200, and prevent the gasket 200 from being displaced when the output shaft of the motor is not passed through the through hole of the gasket 200. Secondly, when installing the wind wheel 100, the output shaft of the motor passes through the marking groove 120, the through hole and the shaft hole 110 in sequence, and the flat position mark is formed on the groove side wall of the marking groove 120. The end surface area of ​​the gasket 200 is larger than the radial cross-sectional area of ​​the marking groove 120. The end surface of the gasket 200 can make the flat position mark provided on the marking groove 120 more eye-catching, so as to achieve the purpose of clearly indicating the flat position direction, so that the operator can find the flat position mark more easily, thereby improving the assembly efficiency of the wind wheel 100.

[0042] Furthermore, the wind wheel 100 is generally an injection-molded part, and forming the flat mark on the mark groove 120 only changes the local injection-molded shape of the wind wheel 100, which does not increase the difficulty of the process. It is relatively simple to implement, more economical and practical, and thus reduces the production cost of the wind wheel structure.

[0043] Reference Figures 3 to 5 The side wall of the marking groove 120 includes a first curvature segment 121 and a first marking segment 122 connected to each other. The flat position mark is formed on the first marking segment 122. The first marking segment 122 is a sudden change segment relative to the first curvature segment 121, so that the first marking segment 122 forms a strong contrast feature, thereby achieving the purpose of clearly indicating the direction of the flat position 111. Therefore, the flat position mark is formed on the first marking segment 122, which can make the flat position mark more eye-catching, thereby improving the assembly efficiency of the wind wheel 100.

[0044] The flat mark is formed in the first mark segment 122 , that is, the flat mark is the first mark segment 122 .

[0045] In one embodiment, the first marking segment 122 is provided as a straight line segment, that is, the flat position mark is formed on the straight line segment, which can make the flat position mark more eye-catching, thereby improving the assembly efficiency of the wind wheel 100.

[0046] In the second embodiment, the first marking section 122 is protruded in a direction away from the center of the first curvature section 121 , so that the flat position mark is more eye-catching, thereby improving the assembly efficiency of the wind wheel 100 .

[0047] In the third embodiment, the first marking section 122 is protruded toward the center of the first curvature section 121 , so that the flat position mark is more eye-catching, thereby improving the assembly efficiency of the wind wheel 100 .

[0048] It should be noted that when the first marking segment 122 is protruding in a direction away from the center of the first curvature segment 121, the cross-section of the first marking segment 122 in the radial direction of the marking groove 120 can be arc-shaped, triangular or trapezoidal, etc., and no specific limitation is made to the cross-section of the first marking segment 122 in the radial direction of the marking groove 120.

[0049] When the first marking segment 122 is protruded toward the direction close to the center of the first curvature segment 121, the cross-section of the first marking segment 122 in the radial direction of the marking groove 120 can be arc-shaped, triangular, trapezoidal, etc., and no specific limitation is made here on the cross-section of the first marking segment 122 in the radial direction of the marking groove 120.

[0050] Optionally, the outer edge of the gasket 200 includes a second curvature segment and a second marking segment 210 that are connected, at least the end face of the second marking segment 210 is exposed from the end face of the axial hole 110, and the flatness mark is formed on the second marking segment 210. It can be understood that the second marking segment 210 is a sudden change segment relative to the second curvature segment, so that the second marking segment 210 forms a strong contrast feature, thereby achieving the purpose of clearly indicating the direction of the flatness 111. Therefore, forming the flatness mark on the second marking segment 210 can make the flatness mark more eye-catching, thereby improving the assembly efficiency of the wind wheel 100.

[0051] The flat mark is formed on the second mark segment 210 , that is, the second mark segment 210 is a flat mark.

[0052] Reference Figure 6 Furthermore, in one embodiment, the second marking segment 210 is provided as a straight line segment, which can make the flat position mark more eye-catching, so that the operator can quickly find the flat position mark, thereby improving the assembly efficiency of the wind wheel 100.

[0053] In the second embodiment, the second marking section 210 is protruding away from the center of the second curvature section, which makes the flat mark more eye-catching, allowing operators to quickly find the flat mark, thereby improving the assembly efficiency of the wind wheel 100.

[0054] In the third embodiment, the second marking section 210 is recessed toward the center of the second curvature section, which makes the flat mark more eye-catching, allowing operators to quickly find the flat mark, thereby improving the assembly efficiency of the wind wheel 100.

[0055] Reference Figure 7 In the fourth embodiment, the gasket 200 is provided with a marking through hole 220, and the flat position mark is the marking through hole 220. In this way, with the cooperation of the side wall of the marking through hole 220 and the end face of the shaft hole 110, the flat position mark can be made more eye-catching, so that the operator can quickly find the flat position mark, thereby improving the assembly efficiency of the wind wheel 100.

[0056] Optionally, the end face of the shaft hole 110 and the gasket 200 have different colors. It can be understood that with the help of color, the flat position mark set on the gasket 200, or the flat position mark formed between the gasket 200 and the end face of the shaft hole 110 can be made more eye-catching, so that the operator can quickly find the flat position mark, thereby improving the assembly efficiency of the wind wheel 100.

[0057] For example, when the flat position mark is formed on the straight section of the marking groove 120, since the end face of the axial hole 110 and the gasket 200 have different colors, that is, the end face of the marking groove 120 and the gasket 200 have different colors, when observed from the axial direction of the axial hole 110, the end face of the marking groove 120 and the surface of the gasket 200 will form an obvious dividing line at the groove side wall of the marking groove 120, and since the straight section is a sudden change section of the first curvature section 121, forming the flat position mark on the straight section will make the flat position mark more eye-catching, so that the operator can quickly find the flat position mark, thereby improving the assembly efficiency of the wind wheel 100.

[0058] When the flat position mark is formed on the second marking segment 210 of the gasket 200 and the second marking segment 210 protrudes in a direction away from the center of the second curvature segment, due to the different colors of the end face of the axial hole 110 and the gasket 200, when observed from the axial direction of the axial hole 110, the end face of the axial hole 110 and the gasket 200 will form an obvious dividing line at the outer edge of the gasket 200, and since the second marking segment 210 protrudes in a direction away from the center of the second curvature segment, the outline of the second marking segment 210 will be more eye-catching, so that the operator can quickly find the flat position mark, thereby improving the assembly efficiency of the wind wheel 100.

[0059] Furthermore, the color of the wind wheel 100 is different from the color of the gasket 200. The wind wheel 100 is an injection molded part. By making the overall color of the wind wheel 100 consistent, the step of later coating to change the color of the end face of the shaft hole 110 can be reduced, thereby improving the production efficiency of the wind wheel structure. Of course, the utility model is not limited to this. In other embodiments, the color of the end face of the shaft hole 110 can also be changed by later coating, so that the color of the end face of the shaft hole 110 and the gasket 200 are different.

[0060] The gasket 200 is a sheet metal part.

[0061] It should be noted that, when a marking groove 120 is provided, the end surface of the shaft hole 111 refers to the top end surface and the bottom wall of the groove 120 .

[0062] Furthermore, the gasket 200 and the wind wheel 100 are insert-molded. It can be understood that by insert-molding the gasket 200 and the wind wheel 100, on the one hand, the installation process of the gasket 200 can be reduced, thereby improving the production process of the wind wheel structure, and on the other hand, the stability of the installation of the gasket 200 can be improved.
