In an existing vibration generator, a rotating body is installed on a rotating shaft of an electric motor, so that the center of gravity of the rotating body deviates from the rotating shaft, and vibration occurs by the rotation of the rotating body.

[0003] The existing vibration generator has a complex structure and high cost. Summary of the Invention

[0004] In view of this, the main technical problem to be solved by the present application is to provide a vibration generator, a vibration generating device, and a material impurity removing device, which simplify the structure and reduce the cost.

[0005] To solve the above technical problem, a technical solution adopted by the present application is: providing a vibration generator for generating vibration. The vibration generator includes a base and a swinging part. The base is used for being installed on an object receiving vibration. The swinging part is fixedly arranged on the base. The swinging part has a windward surface, and the windward surface is used for being inclined relative to the air flow direction, so that the air flow generates a thrust on the swinging part. The thrust changes with the change of the inclination angle of the windward surface relative to the air flow direction, so that the swinging part swings reciprocally relative to the base, and further generates vibration on the base.

[0006] In some embodiments, the swinging part is strip-shaped, and during the process of swinging reciprocally relative to the base, the swinging amplitude gradually increases from the connection end with the base to the free end.

[0007] In some embodiments, the swinging part and the base are formed by an integrated thin plate member, and a part of the thin plate member is bent and inclined relative to another part to respectively serve as the swinging part and the base.

[0008] In some embodiments, the number of the swinging parts is at least two, and the two swinging parts respectively extend obliquely to both sides of the base.

[0009] In some embodiments, the angles between the two swinging parts and the base are equal.

[0010] In some embodiments, the base includes a base main body and two strip-shaped bodies connected to the base main body and arranged side by side with each other. The two swinging parts are located between the two strip-shaped bodies, and the two strip-shaped bodies are used for being installed on an object receiving vibration.

[0011] To solve the above technical problems, the present application further provides a vibration generating assembly, which includes a string and a vibration generator. The string is in a tensioned state; the vibration generator is any one of the above vibration generators, and the base in the vibration generator is mounted on the string and drives the string to vibrate.

[0012] In some embodiments, a plurality of through holes are provided on the base, and the plurality of through holes are arranged at intervals in one direction, and the string is sequentially passed through each through hole.

[0015] Advantages of the present application:

[0016] The vibration generator includes a base and a swinging part. The swinging part is fixedly arranged on the base, and the swinging part has a windward surface, and the windward surface is used to be inclined relative to the air flow direction, so that the air flow generates a thrust on the swinging part, and the thrust changes with the inclination angle of the windward surface relative to the air flow direction, so that the swinging part swings reciprocally relative to the base, and thus generates vibrations on the base. Specifically, when the air flow blows over the swinging part, it generates a thrust perpendicular to the windward surface on the swinging part, and this thrust deforms the swinging part, resulting in a decrease in the above inclination angle, and further resulting in a decrease in this thrust. As this thrust decreases, the swinging part rebounds (resets) under its own elastic force, and again causes the above inclination angle to increase. The thrust and the elastic force change periodically, and the magnitudes of the forces alternate, causing the swinging part to swing reciprocally, and thus generating vibrations on the base. Thus, the vibration generator provided by the present application has a simple structure and low cost. Description of the Drawings

Detailed implementation manners

[0023] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application in conjunction with the drawings. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. Additionally, it should be noted that for the convenience of description, only the parts related to the present application are shown in the drawings, rather than all the structures. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0024] Please refer to Figures 1 to 3 , Figure 1 which is a schematic structural diagram of an embodiment of the vibration generator 40 of the present application in a working state, Figure 2 and Figure 3 are respectively Figure 1 a three-dimensional structural diagram and a top view of the vibration generator 40 shown.

[0025] The vibration generator 40 includes a base 41 and a swinging part 42.

[0026] The base 41 is used to be mounted on an object that receives vibration.

[0027] The swinging part 42 is fixedly arranged on the base 41. The swinging part 42 has a windward surface 421. The windward surface 421 is used to be inclined relative to the airflow direction so that the airflow generates a thrust on the swinging part 42. The thrust changes with the inclination angle of the windward surface 421 relative to the airflow direction, so that the swinging part 42 swings reciprocally relative to the base 41, and thus generates vibration on the base 41.

[0028] Specifically, the airflow blows over the swing part 42, generating a thrust perpendicular to the windward surface 421 on the swing part 42. This thrust deforms the swing part 42, causing the above-mentioned tilt angle to become smaller, and further causing this thrust to become smaller. As this thrust becomes smaller, the swing part 42 rebounds (resets) under its own elastic force, and the above-mentioned tilt angle becomes larger again. The thrust and the elastic force change periodically, and the magnitude of the force alternates, causing the swing part 42 to swing reciprocally, and then generating vibrations on the base part 41. Thus, the vibration generator 40 provided in this embodiment has a simple structure and low cost.

[0029] Optionally, the swing part 42 is in a long strip shape. During the reciprocating swing relative to the base part 41, from the connection end with the base part 41 to the free end ( Figure 1 in the direction from left to right in the figure), the swing amplitude gradually increases. The swing part 42 being in a long strip shape enables the swing part 42 to have better elasticity, and thus can swing better.

[0030] Optionally, the swing part 42 is in a thin plate shape, and one side surface thereof forms the windward surface 421. Figure 1 In the figure, the upper surface of the upper swing part 42 forms the windward surface 421, and the lower surface of the lower swing part 42 forms the windward surface 421. The swing part 42 being in a thin plate shape enables the swing part 42 to have better elasticity, and thus can swing better.

[0031] Optionally, the base part 41 is in a thin plate shape. During use, the base part 41 is arranged parallel to the airflow direction. Thus, the base part 41 can reduce the obstruction to the airflow.

[0032] Optionally, the vibration generator 40 can be a sheet metal part and is formed by bending. Thus, the manufacturing cost can be reduced. Specifically, the swing part 42 and the base part 41 are formed by an integrated thin plate part. A part of the thin plate part is bent and inclined relative to the other part to respectively serve as the swing part 42 and the base part 41. The dotted lines L2 and L3 in the figure show the bending positions.

[0033] When the vibration generator 40 is installed on the string 30 (see the embodiment of the material impurity removal device below), if the swing parts 42 are all arranged on one side of the base part 41, the acting force of the airflow causes the vibration generator 40 to flip from one side of the base part 41 to the other side, which will affect the tilt angle of the windward surface 421 relative to the airflow direction.

[0034] Optionally, the number of the swing parts 42 is at least two (two in the figure), and the two swing parts 42 respectively extend obliquely to both sides of the base part 41. The acting forces of the airflow on the two swing parts 42 are respectively on both sides of the base part 41, which can prevent the vibration generator 40 from flipping, thereby avoiding affecting the tilt angle of the windward surface 421 relative to the airflow direction.

[0035] Furthermore, the angles B between the two swinging parts 42 and the base part 41 are equal. The angle B can be 3° to 8°.

[0036] Optionally, the base part 41 includes a base main body 411 and two strip-shaped bodies 412 that are connected to the base main body 411 and arranged side by side with each other. The two swinging parts 42 are located between the two strip-shaped bodies 412. The above-mentioned objects are two string lines 30 arranged side by side, and the two strip-shaped bodies 412 are respectively fixed on the corresponding string lines 30. The base part 41 is fixed on the two string lines 30, which can prevent the base part 41 from rotating around one of the string lines 30, and further make the base part 41 more stable.

[0037] Specifically, a plurality of through holes 4121 are provided on the strip-shaped body 412, and the plurality of through holes 4121 are arranged at intervals in one direction, and the string line 30 is sequentially passed through each through hole 4121.

[0038] Of course, the base part 41 can also be fixed on the corresponding string line 30 in other ways, for example, by gluing.

[0039] Furthermore, in order to make the base part 41 and the string line 30 fixed more firmly, the plurality of through holes 4121 are not on the same straight line.

[0040] When the object receiving vibration is the string line 30, the airflow blows the vibration generator 40, causing the whole vibration generator 40 to shake, and to a certain extent, it can also drive the string line 30 to vibrate.

[0041] This application also provides a vibration generating assembly. The vibration generating assembly includes a string line 30 and a vibration generator 40. The string line 30 is in a tensioned state. The vibration generator 40 is any one of the above-mentioned vibration generators 40. The base part 41 in the vibration generator 40 is installed on the string line 30 and drives the string line 30 to vibrate. Because the vibration generating assembly has all the technical features of the vibration generator 40, therefore, the vibration generating assembly also has all the technical effects of the vibration generator 40.

[0042] In some embodiments of the vibration generating assembly, a plurality of through holes 4121 are provided on the base part 41, and the plurality of through holes 4121 are arranged at intervals in one direction, and the string line 30 is sequentially passed through each through hole 4121.

[0043] This application also provides a vibration generating device. The vibration generating device includes an airflow generator and a vibration generator 40. The airflow generator is used to generate airflow. The vibration generator 40 is the above-mentioned vibration generator 40. Because the vibration generating device has all the technical features of the vibration generator 40, therefore, the vibration generating device also has all the technical effects of the vibration generator 40.

[0044] Please refer to Figure 4 , Figure 4It is a cross-sectional view of an embodiment of the material impurity removal device of the present application.

[0045] The present application also provides a material impurity removal device. The material impurity removal device includes an air flow generator (not shown in the figure), a bracket 20, a string 30, and a vibration generator 40.

[0046] The air flow generator is used to generate an air flow to drive the movement of the material 1. Specifically, the air flow generator can be a blower or a high-pressure air source, blowing air along the Figure 4 direction of the arrow in the figure. The air flow generator can also be a negative pressure source, and the negative pressure source can also drive the air flow, thereby generating an air flow.

[0047] Specifically, the material 1 can be a semi-finished product in the processing of moxa floss. The moxa floss gathers into a group / strand, and is wrapped or adhered with impurities (such as the stems of mugwort leaves). Moxa floss has a soft property, and under the drive of the air flow, the moxa floss suspends in the air and moves (flutters) along with the air flow. The material 1 can also be other materials, such as cotton.

[0048] The string 30 is stretched on the bracket 20, and the string 30 is in a tensioned state. The string 30 intersects with the air flow direction of the air flow, so that the material 1 can contact the string 30 during the movement along with the air flow. To improve the working efficiency of the material impurity removal device, the number of the strings 30 can be multiple, and the multiple strings 30 are radially distributed around the reference axis L1, wherein the reference axis L1 is parallel to the air flow direction.

[0049] The vibration generator 40 is used to drive the string 30 to vibrate to shake out / eject the impurities in the material 1 that contacts the string 30. For example, the vibration generator 40 generates a standing wave on the string 30. The vibration generator 40 is the vibration generator 40 in the above embodiment.

[0050] The string 30 vibrates under the drive of the vibration generator 40. The material 1 moves under the drive of its own gravity and / or the air flow, and the movement path intersects with the string 30, so that the material 1 can contact the string 30. After the material 1 contacts the string 30, it adheres to the string 30 and moves along the string 30. On the one hand, by using the characteristic that the density of the impurities is relatively large, the impurities are shaken out when the string 30 drives the material 1 to swing. On the other hand, by using the characteristic that the hardness of the impurities is relatively large, the impurities are ejected from the material 1 during the vibration of the string 30. Thus, the separation of the material 1 and the impurities is realized.

[0051] In summary, the present application provides another structure to generate vibration, and the structure is simple and the cost is low.

[0052] Specifically, the above are only the embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present application by the same token.
