Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of entertainment and atmosphere decoration, and more particularly, to a windmill. BACKGROUND

[0002] As a kind of popular entertainment and atmosphere decoration, windmill is deeply loved by people, especially children. Windmill can be held in hand as a handheld toy, or installed in a certain position as a decorative item. The traditional windmill generally has a central component (such as a central shaft) and a plurality of rotating components (such as blades) connected to the central component, and the rotating components can rotate around the central component to generate interest. For example, in a typical scenario, the blades of the windmill can rotate in the wind. In order to improve the interest of the windmill, the prior art has a technical solution of adding a light source to the windmill to make the windmill have a light-emitting effect. However, how to further improve the interest of the windmill is still a problem to be solved by those skilled in the art. CONTENT OF THE UTILITY MODEL

[0003] The present application provides a windmill, which aims to improve the interest of the windmill.

[0004] The windmill provided by the present application comprises a central component, a rotating component connected to the central component, and a swinging component located in front of the rotating component and swingably connected to the central component. The swing of the swinging component increases the interest of the windmill.

[0005] In a possible implementation, the swinging component is connected to the central component through a connecting mechanism to realize its swing. The connecting mechanism comprises a block and a seat body connected to the swinging component and the central component respectively, and the seat body is provided with a constraint cavity, and the block is located in the constraint cavity. The connecting mechanism realizes the swing of the swinging component with a simple structure, and since the block has a high degree of freedom, it can realize various forms of swing.

[0006] Optionally, the center of the block or a contact end provided on the block for contacting the inner wall of the constraint cavity coincides with the projection of the center of gravity of the swinging component on a horizontal plane. In this way, the swing of the swinging component can be realized by its own weight without the need to specially set a driving source to drive the swing of the swinging component.

[0007] In a possible implementation, the middle part of the swinging component is aligned with the central component.

[0008] Optionally, the rotating component is a blade structure, and the swinging component is a circle or a regular polygon when viewed from the front of the windmill. An end of the swinging component away from the central component is exposed from the outer periphery of the swinging component and surrounds the swinging component. In this way, a sunflower disc structure is formed, which increases the interest of the windmill in appearance. When viewed from the front of the windmill, the swinging component looks like the middle of the disc, and the outer end of the rotating component looks like a sunflower petal.

[0009] In one possible implementation, the swinging component is plate-shaped and protrudes towards the front of the windmill to form a containing space with an opening facing the back of the windmill. In this way, the connecting structure of the swinging component and the central component can be arranged in the containing space and be shielded by the swinging component and the rotating component, so as to be basically hidden and not exposed to the user's view, thereby avoiding adversely affecting the appearance of the windmill.

[0010] In one possible implementation, the windmill provided by the application is provided with a light source, and the central component, the rotating component and / or the swinging component are at least partially made of transparent material. In this way, the windmill has a light-emitting effect, thereby increasing the interest.

[0011] In one possible implementation, the windmill provided by the application further comprises a plug-in assembly, a middle part of the plug-in assembly is connected to the central component, and an outer periphery of the plug-in assembly is provided with at least three plug-in slots distributed in a circumferential direction, and each plug-in slot is provided with one rotating component. When viewed from the back of the windmill, the plug-in assembly and the rotating components form a flower shape, thereby improving the interest of the windmill in appearance.

[0012] Optionally, the surface of the swinging component is provided with an expression pattern of a person or an animal. In use, the rotating component rotates, and the swinging component swings, and the whole windmill looks like a moving and living flower, thereby effectively increasing the interest.

DETAILED DESCRIPTION

[0058] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain this application and are not used to limit this application.

[0059] It should be noted that in the following description, the directions or positional relationships indicated by the terms "front", "back", "left", "right", "up", "down", etc. are based on the windmill. Figure 1 As shown in the figure, "front" refers to the direction toward which the windward side of the windmill faces, and correspondingly, "rear" refers to the direction opposite to the "front" direction. The coordinate axes of each direction constitute a three-dimensional rectangular coordinate system, with "front," "rear," "left," and "right" representing horizontal directions, and "up" and "down" representing vertical directions. It should be understood that these terms and coordinate systems are used only to simplify the description and facilitate a clear description of the technical solution. Unless otherwise specified, they do not constitute any limitation on the scope of protection of this application.

[0060] In addition, the terms "first" and "second" in this application are only used to distinguish different features, and do not limit the number or order of features.

[0061] The present application provides a windmill, in a first embodiment, as Figures 1 to 3 As shown, the windmill includes a central component 100 , a rotating component 200 connected to the central component 100 , and a swing component 300 . The swing component 300 is located in front of the rotating component 200 and is swingably connected to the central component 100 .

[0062] Compared with the prior art, the windmill provided by this embodiment has the beneficial effect that a swinging component 300 is provided in front of the rotating component 200, and the swinging of the swinging component 300 increases the interest of the windmill.

[0063] In the first embodiment, the swinging member 300 is not limited in the manner in which it swings, and there are many ways to achieve the swinging of the swinging member 300. For example, Figure 3 As shown, the swing component 300 is connected to the central component 100 via a first connecting mechanism 501 to achieve swinging; Figure 5 As shown, the swing component 300 is connected to the central component 100 via a third connection mechanism 503 to achieve swinging; these two connection mechanisms will be further described below.

[0064] For example, Figure 4As shown, the swing component 300 can also be connected to the central component 100 through an elastic element (such as a spring 502) to achieve swing. In this example, when the swing component 300 is not touched, it remains in the position shown in FIG. Figure 4 Once touched, the external force causes the spring to deform, and after the external force disappears, the swing member 300 swings under the action of the spring force.

[0065] In the first embodiment, the central component 100 is generally a shaft-like component, which can be solid or hollow. The central component 100 itself can be fixed or rotated. The rotating component 200 and the swinging component 300 are both connected to the central component 100, with the swinging component 300 located in front of the rotating component 200. Thus, when viewed from the front of the windmill, not only the rotation of the central component 100 but also the swinging of the swinging component 300 creates an interesting visual experience.

[0066] In the first embodiment, the shape and structure of the rotating component 200 are not limited. For example, it can be any blade in the prior art, such as Figures 1 to 5 For example, as shown in the blade Figures 3 to 5 As shown, the rotating component 200 can be connected to the central component 100 through a first connecting member 201; the first connecting member 201 can be a bearing, the inner ring of the bearing is fixedly connected to the central component 100, and the outer ring of the bearing is fixedly connected to the rotating component 200.

[0067] In the first embodiment, illustratively, Figure 1 、 Figure 16 and Figure 17 As shown, the rotating part 200 can be a blade structure. When viewed from the front of the windmill (ie, facing the windmill), the swinging part 300 is circular (eg, Figure 16 ) or regular polygons (as Figure 17 (As shown in the figure), the radius R1 of the swinging member 300 is less than the radius R2 of the circumferential rotation path P of the outer end of the rotating member 200. It should be noted that when the swinging member 300 is a regular polygon, the radius refers to the radius of its circumscribed circle. In this example, the number of sides of the regular polygon can be any positive integer greater than or equal to 3.

[0068] In this example, when the windmill is viewed from the front, the outer end of the rotating component 200 (i.e., the end away from the central component 100) is not blocked by the swinging component 300, thereby forming a structure similar to a sunflower disk, which adds interest to the windmill's appearance. In this sunflower disk structure, the swinging component 300 forms the middle part of the disk, and the outer ends of the multiple rotating components 200 surround the swinging component 300 to form the petals of the disk. In addition, Figure 1 and Figure 16As shown, the surface of the swing component 300 can be provided with various expression (e.g. smiley) patterns, making the pinwheel more appealing and infectious, and further improving the fun of the pinwheel.

[0069] In the first embodiment, the material of the central component 100, the rotating component 200 and the swing component 300 is not limited. For example, they can be made of plastic material, or other materials such as metal material or hard paper material.

[0070] In the first embodiment, the pinwheel is not limited in how to be fixed to an external object. For example, as shown in Figure 2 and Figure 3 , the pinwheel can be fixedly connected to an external object, such as the top end of a playground or kindergarten fence, through the sleeve-shaped second connecting member 400 provided on the central component 100. As shown in Figure 4 , a rod member 401 can also be provided below the central component 100 for a user to hold the pinwheel for entertainment. As shown in Figure 5 , a flange 402 can also be provided at the tail end of the central component 100 for connecting to an external object.

[0071] In the second embodiment, as shown in Figure 3 and Figure 5 , the swing component 300 can be connected to the central component 100 through a connecting mechanism 500 to realize self-swinging. As shown in Figures 6 to 12 , the connecting mechanism 500 can include a block 510 and a seat 520, the block 510 being connected to one of the swing component 300 and the central component 100 (in Figures 6 to 12 , the block 510 is connected to the swing component 300), and the seat 520 being connected to the other (in Figures 6 to 12 , the seat 520 is connected to the central component 100); the seat 520 is provided with a constraint cavity 530, and the block 510 is located in the constraint cavity 530 and can move (e.g. translate and / or rotate) relative to the seat 520.

[0072] The present embodiment provides a way to realize the swinging of the swing component 300. In the present embodiment, the block 510 is located in the constraint cavity 530 of the seat 520, and the block 510 can move relative to the seat 520; the swing component 300 and the central component 100 are respectively connected to the block 510 and the seat 520, so that the swing component 300 can move relative to the central component 100, thereby realizing swinging. The connecting mechanism provided in the present embodiment can realize the swinging of the swing component 300 with a simple structure, and the block 510 has a high degree of freedom, so that various forms of swinging can be realized.

[0073] In the present embodiment, the shapes of the block 510, the seat 520, the constraint cavity 530, and the opening of the constraint cavity 530 are not limited. For the block 510 and the constraint cavity 530, they can have various shapes as long as the block 510 can be constrained in the constraint cavity 530 and the block 510 can move relative to the seat 520.

[0074] In the present embodiment, the block 510 can be provided with a blocking portion 5101 (as shown in Figures 11 to 13 ), or can not be provided with a blocking portion (as shown in Figure 10 ). When not provided with a blocking portion, the block 510 can be put into the constraint cavity 530 of the seat 520 from the vertical direction, as shown in Figure 10 ; even if the constraint cavity 530 can only limit the block 510 from moving in the horizontal direction and moving downward (when subjected to an external upward force, the block 510 can move upward and leave the constraint cavity 530), the block 510 can still be kept in the constraint cavity 530 to realize the swing of the swing component 300.

[0075] When provided with a blocking portion 5101, the blocking portion 5101 can prevent the block 510 from leaving the constraint cavity 530 from the opening of the constraint cavity 530, as shown in Figures 11 to 13 . Exemplarily, when the opening of the constraint cavity 530 is circular and the block 510 is a sphere, the diameter W1 of the opening is smaller than the diameter W2 of the block 510, and the upper part of the block 510 can act as a blocking portion to prevent the block 510 from leaving the constraint cavity 530 from the opening, as shown in Figure 9 .

[0076] Exemplarily, Figures 6 to 13 five different connection mechanisms 500 are shown, which are described as follows:

[0077] Figure 6 and Figure 9 A first connection mechanism 501 is shown, which includes a first block 511 and a first seat 521 provided with a first constraint cavity 531; wherein the first block 511 and the first constraint cavity 531 are spherical; the upper part of the first block 511 can act as a blocking portion to prevent the first block 511 from leaving the first constraint cavity 531;

[0078] Figure 10 A variant of the first connection mechanism is shown, which includes a second block 5111 and a second seat 5211 provided with a second constraint cavity 5311; wherein the second block 5111 is spherical and the second constraint cavity 5311 has a U-shaped cross section; the diameter of the second block 5111 is not greater than the diameter of the opening of the second constraint cavity 5311, and the second block 5111 does not have a blocking portion;

[0079] Figure 7 andFigure 8 The third connecting mechanism 503 is shown, which includes a third block 513 and a third seat 523, and the third seat 523 is provided with a third constraint cavity 533; wherein the third block 513 and the third constraint cavity 533 are spherical, and the part of the third block 513 close to the outlet of the constraint cavity 533 can be used as a blocking part to prevent the third block 513 from being taken out of the constraint cavity 533; the third connecting mechanism will be further described below;

[0080] Figure 11 The fourth connecting mechanism is shown, which includes a fourth block 514 and a fourth seat 524, and the fourth seat 524 is provided with a fourth constraint cavity 534; wherein the upper part of the fourth block 514 is a spherical fourth blocking part 5141, the lower part is a fourth tapered part 5142, and the fourth constraint cavity 534 is spherical;

[0081] Figure 12 The fifth connecting mechanism is shown, which includes a fifth block 515 and a fifth seat 525, and the fifth seat 525 is provided with a fifth constraint cavity 535; wherein the upper part of the fifth block 515 is a spherical fifth blocking part 5151, and the lower part is a fifth tapered part 5152, and the upper part of the fifth constraint cavity 535 is spherical, and the lower part is tapered; in this example, a gap can be provided between the fifth tapered part 5152 and the inner wall of the lower part of the fifth constraint cavity 535, or no gap can be provided. When the gap is provided, the fifth block 515 can rotate and translate; when no gap is provided, the fifth block 515 can only rotate around its own axis.

[0082] Figure 13 The sixth connecting mechanism is shown, which includes a sixth block 516 and a sixth seat 526, and the sixth seat 526 is provided with a sixth constraint cavity 536; wherein the upper part of the sixth block 516 is a spherical sixth blocking part 5161, and the lower part is an inner recess 5162, and the upper part of the sixth constraint cavity 536 is spherical, and the lower part is tapered. It can be understood that the outer wall of the inner recess 5162 can be other shapes in addition to the shape shown. Figure 13

[0083] In the second embodiment, the direction and amplitude of rotation of the block 510 can not be limited. Taking the third connecting mechanism 503 as an example, as shown in Figure 7 and Figure 8 ​As shown, the rotation direction and amplitude of the block 510 can be controlled in the following manner: a conical groove 5033 connected to the constraint cavity 530 is provided in the base 520, the block 510 is connected to the swing component 300 via a horizontal rod 5031, and the portion of the horizontal rod 5031 close to the block 510 is located in the conical groove 5033; in this way, the horizontal rod 5031 can swing horizontally, and the swing angle is limited by the inner wall of the conical groove 5033; in the vertical direction, a pad 5032 is provided above and below the horizontal rod 5031 respectively, and the two pads 5032 are in contact with the upper wall and the lower wall of the conical groove 5033 respectively, so that the horizontal rod 5031 will not move up and down; that is, in Figure 7 and Figure 8 In the illustrated embodiment, the block 510 only rotates horizontally, and accordingly, the swing component 300 only swings horizontally within a certain angle.

[0084] In the second embodiment, the location of the connection mechanism 500 is not limited. Figure 3 and Figure 5 It can be seen that the connecting mechanism can be arranged at different positions. Figure 3 In the embodiment, the first connecting mechanism 501 is provided on the upper portion of the swing member 300; Figure 5 In the embodiment, the third connecting mechanism 503 is disposed in the middle of the swing component 300 .

[0085] In a third embodiment, if Figures 11 to 13 As shown, block 510 is provided with a contact end 540 for contacting the cavity wall of confinement cavity 530. Contact end 540 contacts the inner wall of confinement cavity 530 with a very small area. Exemplarily, contact end 540 and the cavity wall of confinement cavity 530 may be in point contact, line contact, or surface contact (with a very small contact area). Figures 11 to 13 In the embodiment, the fourth block 514 , the fifth block 515 and the sixth block 516 are respectively provided with a fourth contact end 544 , a fifth contact end 545 and a sixth contact end 546 . Figures 6 to 10 The blocks 510 shown are spherical and have a large surface contact area with the inner wall of the constraint cavity 530. In contrast, the blocks 510 provided in this embodiment have contact ends 540, which have a very small surface contact area with the inner wall of the constraint cavity 530. This can reduce friction between the blocks 510 and the constraint cavity 530, thereby improving the flexibility of the blocks 510.

[0086] The structure provided by the embodiment is particularly suitable for the case where the contact end 540 coincides with the projection of the center of gravity of the swing component 300 on the horizontal plane. At this time, the contact end 540 of the block 510 is pressed against the bottom end of the constraint cavity 530 by the gravity of the swing component 300, and the bottom end of the constraint cavity 530 supports the block 510 and the swing component 300 connected with the block 510. In this way, the swing component 300 can generate a swing effect by using its own gravity, i.e., even if a driving source is not specially arranged to apply a driving force to the swing component 300 to drive it to swing, the swing effect can be generated. The case where the swing component 300 swings by using its own gravity will be further described below.

[0087] In the fourth embodiment, as shown in Figure 14 and Figure 15 , a limiting block 550 is fixed on the block 510 of the connecting mechanism, and a limiting groove 560 is formed on the seat 520, and the limiting block 550 is located in the limiting groove 560 to limit the movement range (e.g., the translation and / or rotation range) of the block 510 in the constraint cavity 530, thereby limiting the swing range of the swing component 300. Compared with the embodiments shown in Figure 7 and Figure 8 , the fourth embodiment provides another structure for controlling the rotation direction and range of the block 510, which makes the block 510 have more degrees of freedom and at the same time can control the rotation angle of the block 510 in each degree of freedom.

[0088] As shown in Figure 15 , in the fourth embodiment, the constraint cavity 530 can be upwardly open, and the limiting groove 560 also has an upwardly open and extends in the left-right direction and communicates with the constraint cavity 530; correspondingly, the limiting block 550 is arranged on the left side and / or the right side of the block 550. A gap is provided between the limiting block 550 and the bottom wall of the limiting groove 560, so that the block 510 can rotate around the axis R2 extending in the front-rear direction, thereby making the left and right ends of the swing component 300 swing up and down. A gap is provided between the limiting block 550 and the front and rear side walls of the limiting groove 560, so that the block 510 can rotate around the axis R3 extending in the left-right direction and also around the axis R1 extending in the up-down direction. When the block 510 rotates around the axis R3, the front and rear ends of the swing component 300 swing up and down, thereby generating a nodding effect of the swing component. When the block 510 rotates around the axis R1, the left and right ends of the swing component 300 swing front and rear, thereby generating a shaking effect of the swing component.

[0089] The rotation range of the block 510 in each direction can be adjusted by changing the gap size between the limiting block 550 and the inner wall of the limiting groove 560. Figure 15In the embodiment, the distance between the limiting block 550 and the bottom wall of the limiting groove 560 is larger, and the distance between the limiting block 550 and the front and back side walls is smaller; therefore, the block 510 rotates at a larger angle around the axis R2, and rotates at a smaller angle around the axis R3 and the axis R1.

[0090] In the fourth embodiment, the shape of the limiting block 550 is not limited. Figure 15 In the embodiment, the shape of the limiting block 550 is a cuboid; by Figure 15 It is easily predictable that the limiting block 550 can also be a cylinder. In the embodiment, the number of the limiting block 550 is not limited. Figure 15 In the embodiment, the number of the limiting block 550 is two, and the limiting block 550 is symmetrically distributed on the left and right sides of the block 510; by Figure 15 It is easily predictable that the number of the limiting block 550 and the limiting groove 560 can also be more, for example, three or four. In the embodiment, the extending direction of the limiting groove 560 is not limited. Figure 15 In the embodiment, the limiting groove 560 extends in the left-right direction; by Figure 15 It is easily predictable that the limiting groove 560 can also extend in the front-back direction.

[0091] In the fifth embodiment, as shown in Figure 18 and Figure 19 , the middle part 301 of the swing component 300 can be aligned with the center component 100, so as to facilitate the alignment of the middle part 301 of the swing component 300 with the middle part of the rotating component 200, and further form the sunflower disc structure mentioned above, and increase the interest of the windmill. Exemplarily, the middle part 301 of the swing component 300 can be aligned with the center component 100 by the following structure: as shown in Figure 18 and Figure 19 , the connecting mechanism 500 can be connected to the upper side of the center component 100 through the first connecting rod 601, and the connecting mechanism 500 connects the upper part of the swing component 300.

[0092] In addition, optionally, in the embodiment, the gravity center of the swing component 300 and the center of the block 510 of the connecting mechanism are both on the projection of the horizontal plane; as shown in Figure 18 and 19 , they are on the same vertical straight line H. In this way, the weight of the swing component 300 can participate in the swing of the swing component 300 (i.e. the case that the swing component 300 swings by using its own gravity); when there is no external force, the swing component 300 is in Figure 1 , Figure 18 and Figure 19The static state is shown; when the swing member 300 is blown by the wind, the center of gravity of the swing member 300 deviates from the original position, the weight of the swing member 300 will move the swing member 300 to the original position, and then the swing member 300 will swing back and forth (usually irregularly) until the swing member 300 returns to the static state. The windmill provided by the embodiment does not need to be intentionally pushed, and can swing by natural wind or shaking of the windmill when holding the windmill, thereby effectively increasing the interest of the windmill.

[0093] In the embodiment, the middle part 301 of the swing member 300 is aligned with the center part 100, which means that the middle part 301 of the swing member 300 and the center part 100 are projected on the vertical plane and coincide; preferably, the center of the swing member 300 and the center of the center part 100 are projected on the vertical plane and substantially coincide.

[0094] In the embodiment, the lower end of the first connecting rod 601 is connected to the center part 100, and the upper end is connected to the connecting mechanism 500, and the specific part of the connecting mechanism 500 is not limited; the upper end of the first connecting rod 601 can be connected to the seat body 520 (as shown in Figure 18 ), or can be connected to the block body 510 (as shown in Figure 19 ).

[0095] In the embodiment, the connecting mechanism 500 is not limited in how to connect the swing member 300. As shown in Figure 18 , the connecting mechanism 500 can be used as a support structure to connect the upper part of the swing member 300; as shown in Figure 19 , the connecting mechanism 500 can also be used as a suspension structure to connect the top end of the swing member 300, and the swing member 300 is hung below the connecting mechanism 500. Correspondingly, the shape of the first connecting rod 601 is not limited, for example, it can be a straight line as shown in Figure 18 , or can be an L shape as shown in Figure 19 .

[0096] In the sixth embodiment, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 14 and Figure 18 , the swing member 300 can be plate-shaped and protrude forward of the windmill to form an accommodation space 302 (as shown in Figure 3 ) with an opening facing the rear of the windmill. Optionally, in the embodiment, as shown in Figure 18 , the connecting mechanism 500 can be connected to the swing member 300 through the second connecting rod 602, and the second connecting rod 602, the connecting mechanism 500 and the first connecting rod 601 are all located inside the accommodation space 302.

[0097] In the embodiment, the swing member 300 is provided in a plate shape (may also be referred to as a thin-walled shape) and protrudes towards the front of the pinwheel, forming a containing space 302 with an opening facing the rear of the pinwheel. In this way, the connecting mechanism 500 can be arranged inside the swing member 300. When the center of the block 510 of the connecting mechanism 500 and the center of gravity of the swing member 300 coincide in the projection on the horizontal plane (or the contact end 540 and the center of gravity of the swing member 300 coincide in the projection on the horizontal plane), and the swing member 300 is not pushed by external force, the swing member 300 can be in the static state as shown in Figure 1 、 Figure 2 and Figure 18 . In the static state, the connecting structure (including the connecting mechanism 500, the first connecting rod 601 and the second connecting rod 602) of the swing member 300 and the central member 100 are all located inside the swing member 300; when the swing member 300 is close to the rotating member 200 behind it, the above connecting structure will not be exposed in the user's field of view, as shown in Figure 1 、 Figure 2 and Figure 18 , so that the pinwheel appearance is simple and beautiful, and will not be affected by the connecting structure. In practice, by reasonably setting the swing amplitude of the swing member 300, the above connecting structure can be basically hidden and will not be exposed in the user's field of view not only in the above static state, but also in the use process of the pinwheel.

[0098] If the containing space 302 is not provided, for example, as shown in Figure 19 , the swing member 300 is in a flat plate shape, and the above connecting structure cannot be hidden inside the swing member 300, and in order to make the horizontal projection of the center of the block 510 and the center of gravity of the swing member 300 coincide, the block 510 and the seat 520 need to be arranged above the swing member 300; in this way, the appearance of the pinwheel will be adversely affected, and the sunflower disc type appearance as shown in Figure 1 and Figure 2 cannot be formed.

[0099] In the embodiment, as shown in Figure 18 , the cross-sectional shape of the swing member 300 can be substantially arc-shaped or square; the embodiment does not limit this.

[0100] Exemplarily, as shown in Figure 18 , the second connecting rod 602 can be in a straight line shape, the upper end of the second connecting rod 602 is connected to the upper part of the back surface of the swing member 300, and the lower end is connected to the block 510 of the connecting mechanism.

[0101] In the seventh embodiment, as shown in Figures 20 to 22As shown, the windmill provided by the present application further comprises a shaft sleeve 700, and the central component 100 is a center shaft matched with the shaft sleeve 700, which is inserted into the shaft sleeve 700 to rotate within a preset angle range T. Compared with the swing of the swing component 300 realized by using the connecting mechanism, the present embodiment provides another way to realize the swing, i.e., the central component 100 is arranged to be able to rotate within a preset angle range, so that the swing component 300 can swing within the preset angle range along with the rotation of the central component 100.

[0102] As shown, Figure 21 the central component 100 can rotate bidirectionally along the direction S relative to the shaft sleeve 700, so as to enable the swing component 300 to swing back and forth about the axis R4 (as shown). Figure 20 When viewed in the front-rear direction, the rotation of the swing component 300 about the axis R4 appears as the up-down swing of the left and right ends of the swing component 300. The swing amplitude of the swing component 300 is determined by the preset angle range. Exemplarily, as shown, Figure 22 the two opposite side walls of the limiting groove 701 opened in the inner wall of the shaft sleeve 700 define an exemplary preset angle range T, and the limiting blocks 101 arranged on the outer periphery of the central component 100 can only rotate within the angle range.

[0103] Figure 22 In the embodiment shown, the swing amplitude of the swing component 300 is also related to the length of the limiting blocks 101; when the length of the limiting blocks 101 is larger, the swing amplitude is smaller, and when the length of the limiting blocks 101 is smaller, the swing amplitude is larger. Specifically, as shown, Figure 21 the number of the limiting blocks 101 can be four, which are distributed along the circumference of the central component 100; correspondingly, the number of the limiting grooves 701 is also four, which correspond to the limiting blocks 101 one by one.

[0104] It can be understood that, Figures 20 to 22 the structure provided for realizing the rotation of the central component 100 within the preset angle range is exemplary, and other structures obtained by the person skilled in the art without creative labor are also within the protection scope of the present application. In addition, the way provided by the present embodiment for realizing the swing of the swing component 300 can be used alone or together with other ways for realizing the swing of the swing component 300 (for example, using the connecting mechanism 500).

[0105] In the eighth embodiment, the windmill provided by the present application has a light source, and the central component 100, the rotating component 200 and the swing component 300 are at least partially made of light-transmitting material, so that the whole or part of the windmill has a light-emitting effect, to further improve the interest of the windmill.

[0106] In the embodiment, any one, two or all of the center part 100, the rotating part 200 and the swinging part 300 are provided with a light-transmitting material. "At least partially made of a light-transmitting material" means that any one of them can be partially made of a light-transmitting material, or all of them can be made of a light-transmitting material.

[0107] In the embodiment, the setting position of the light source is not limited. For example, the light source can be set on the center part 100; specifically, the light source can be set on the front end of the swinging part 300 close to the center part 100. For another example, the light source can also be set on the part of the rotating part 200 behind the swinging part 300. For another example, the light source can also be set on the back of the swinging part 300. The embodiment does not limit the specific position of the light source.

[0108] In the ninth embodiment, as shown in Figures 23 to 25 Fig. 9, the windmill provided by the application further comprises a plug-in assembly 800, the middle part 801 of the plug-in assembly 800 is connected with the center part 100, and the outer periphery of the plug-in assembly 800 is provided with at least three plug-in slots 802 distributed in the circumferential direction, and each plug-in slot 802 is provided with one rotating part 200.

[0109] The embodiment provides a connection structure of the rotating part 200 and the center part 100, that is, the rotating part 200 is connected with the center part 100 through the plug-in assembly 800. In the embodiment, the rotating part 200 is plugged into the outer periphery of the plug-in assembly 800, and the middle part 801 of the plug-in assembly 800 is fixedly connected or rotatably connected with the center part 100.

[0110] The structure provided by the embodiment has at least the following three advantages: first, the rotating part 200 is plugged into the plug-in assembly 800 to form a flower-shaped structure (the rotating part 200 is similar to a petal, and the plug-in assembly 800 is similar to the middle part of a flower), which can improve the interest of the windmill; second, the rotating part 200 and the plug-in assembly 800 are detachably connected, which facilitates the replacement of the rotating part 200 and the formation of various appearances capable of improving the interest of the windmill by using rotating parts 200 of different shapes; third, the rotating part 200 and the plug-in assembly 800 are of a split structure, so that they can be manufactured separately and finally assembled, which is beneficial to improving the manufacturing efficiency and quality of the windmill.

[0111] In the tenth embodiment, as shown in Figure 26 and Figure 27 the plug-in assembly 800 comprises a front plate member 803 and a rear plate member 804 which are detachably connected, and they are both evenly divided into at least three visually independent components 8031, 8041 in the circumferential direction, and the gap between each component 8031 of the front plate member 803 and the component 8041 of the rear plate member 804 aligned therewith forms the plug-in slot 802.

[0112] The structure provided by the embodiment has at least the following three advantages: first, the plug-in assembly 800 is divided into visually independent components, so that the plug-in assembly 800 can be used as the middle part of the flower as a whole, and each visually independent component can be used as a part of the petal, thereby enriching the form of the flower-shaped structure and increasing the interest of the windmill; second, the plug-in assembly 800 is a split structure, and different front and rear plate members can be combined to form various flower appearances, thereby improving the interest of the windmill; and third, the front and rear plate members can be manufactured separately and then assembled, which is beneficial to improving the manufacturing efficiency and quality of the windmill.

[0113] As shown in Figure 26 , the front plate member 803 and the rear plate member 804 can be combined into the plug-in assembly 800 by moving close to each other along the axis R5. Similarly, Figure 27 , the front plate member 803 and the rear plate member 804 can be combined into the plug-in assembly 800 by moving close to each other along the axis R6. When the plug-in assembly 800 is combined, the front plate member 803 and the rear plate member 804 are provided with gaps in the extension direction of the axis R6; the gap between each component part 8031 of the front plate member 803 and the component part 8041 of the rear plate member 804 aligned with the component part 8031 can form the insertion slot 802, so that one end of the rotating member 200 is inserted into the insertion slot 802 to realize the connection between the rotating member 200 and the plug-in assembly 800.

[0114] Exemplarily, as shown in Figure 26 and Figure 27 , the detachable connection between the front plate member 803 and the rear plate member 804 and the connection between the rotating member 200 and the plug-in assembly 800 can be realized in the following manner. Each component part of the rear plate member 804 is provided with a forwardly extending pin 805, and each pin 805 is correspondingly provided with a pin hole column 806 in the front plate member 803, as shown in Figure 26 ; each pin hole column 806 has a pin hole 8061, as shown in Figure 27 . Some component parts of the rear plate member 804 are provided with a lock block 807, and the front plate member 803 is correspondingly provided with a lock hole 808, as shown in Figure 26 . The lock block 807 is made of elastic material. As shown in Figure 26 , when the front plate member 803 and the rear plate member 804 move close to each other along the axis R5 to a certain extent, the lock block 807 is inserted into the lock hole 808; during the insertion, the lock block 807 deforms by relying on its elasticity; after the insertion, the lock block 807 resets, and the head of the lock block 807 is blocked by the edge of the lock hole 808 and cannot move in the front-rear direction, thereby realizing the relative fixation of the front plate member 803 and the rear plate member 804 in the front-rear direction. At the same time, the lock block 807 is blocked by the inner wall of the lock hole 808, and the front plate member 803 is fixed relative to the rear plate member 804 in the circumferential direction, the up-down direction and the left-right direction.

[0115] In order to realize the connection between the rotating member 200 and the plug-in assembly 800, asFigure 28 As shown, the rotating part 200 is provided with a connecting hole 202 which is used in cooperation with the pin 805 on the rear plate 804, and an avoiding hole 203 which corresponds to the position of the lock block 807. Before the front plate 803 and the rear plate 804 are close to each other to realize the locking, all the rotating parts 200 are pre-fixed to the rear plate 804; that is, the rotating parts 200 are placed in front of the rear plate 804, and the pin 807 provided on the rear plate 804 is inserted through the connecting hole 202 of the rotating part 200 (at the same time, if there is a lock block 807, the lock block 807 is inserted through the avoiding hole 203).

[0116] After all the rotating parts 200 are pre-fixed to the rear plate 804, the front plate 803 is close to the rear plate 804 along the axis R5, the pin 807 is inserted into the pin hole 8061 of the pin hole column 806, and the lock block 807 enters the lock hole 808, so that the connection of the front plate 803 and the rear plate 804 and the connection of the rotating part 200 and the plug-in assembly 800 can be realized. At this time, one end of each rotating part 200 close to the center part 100 is located in the gap between the front plate 803 and the rear plate 804; at the same time, the rotating part 200 is fixed by the two pins 805 and cannot be taken out of the slot of the plug-in assembly 800, nor can it move relative to the plug-in assembly 800.

[0117] In the connection mode of the rotating part 200 and the plug-in assembly 800 provided in the embodiment, the rotating part 200 is connected to the plug-in assembly 800 through the pin 805, instead of being directly rigidly connected to the center part 100; this connection mode makes the rotating part 200 better bear force and have better force effect, and it will not be easily broken.

[0118] Exemplarily, as shown in Figure 26 The middle part of the front plate 803 can be provided with an outer sleeve 809, and the middle part of the rear plate 804 can be provided with an inner sleeve 810; the size of the outer sleeve 809 matches the size of the inner sleeve 810, that is, the inner diameter of the outer sleeve 809 is equal to the outer diameter of the inner sleeve 810. In this way, the front plate 803 and the rear plate 804 can be easily centered, thereby improving the assembly efficiency of the two.

[0119] In the embodiment, the "visually independent component" refers to a component which can be visually distinguished from other components (for example, adjacent components). For example, the surface of a disc is drawn with several straight lines extending along the radius, which divides the disc into several sectors; then the sectors are the visually independent components of the disc. Figure 26 and Figure 27In the embodiment, each component 8031, 8041 of the front plate 803 and the rear plate 804 can be visually distinguished from adjacent components 8031, 8041 by means of a partition 811 extending in the front-to-back direction, thereby forming a visually independent part. Specifically, the components 8031, 8041 and the partition 811 can be an integrated structure. Figure 26 and Figure 27 The number of visually independent components is eight.

[0120] like Figure 23 As shown, when the windmill is viewed from the rear, the plug assembly 800 is exposed to the field of vision. The visually independent components distributed circumferentially form a petal shape, reminiscent of a flower, thereby further enhancing the interest of the windmill from an appearance perspective.

[0121] It should be noted that the embodiments of the present application provided above can be combined in a reasonable manner to form new embodiments; for example, Figure 1 、 Figure 16 and Figure 17 The first embodiment with a sunflower disk structure can be combined with the ninth embodiment with a plug-in assembly 800 to form an eleventh embodiment. In the eleventh embodiment, the windmill provided by the present application includes Figure 1 and Figure 2 The central component 100, the rotating component 200, the swing component 300 and Figure 23 The plug assembly 800 shown in FIG. 1 has at least three slots 802 distributed along the circumference of the plug assembly 800 (eg, Figure 24 As shown), each slot 802 is provided with a rotating component 200 (as shown Figure 25 As shown, the rotating component 200 is a blade structure and the first end 204 (as Figure 28 As shown) inserted into slot 802; viewed from the front of the windmill, as Figure 1 、 Figure 16 and Figure 17 As shown, the swing component 300 is circular or regular polygonal, the plug assembly 800 is blocked, and the second end 205 of the rotating component 200 (as shown in FIG. Figure 28 The second ends 205 of at least three rotating components 200 are evenly distributed along the outer periphery of the swinging component 300. Thus, the windmill provided by the present application has the advantages of both the sunflower disk structure and the plug assembly 800.

[0122] In this embodiment, the rotating part 200 and the plug-in assembly 800 can form a flower structure and shape; in addition, various human or animal expression patterns can be provided on the surface of the swinging part 300; in this way, in use, the rotating part 200 rotates, the swinging part 300 swings, and the whole windmill looks like a moving, living flower, thereby effectively increasing the interestingness.

[0123] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
