It is more convenient to implement solid-liquid separation for a drinking cup adopting such a rotating mechanism, and the user experience is significantly improved.

Description

Technical Field

[0001] The present invention relates to a transmission mechanism, in particular to a mechanism for implementing rotation, a cup lid using such a rotation mechanism, and an application in cup manufacturing. Background Art

[0002] Tea is an important part of Chinese culture. Therefore, making tea has driven the development of various aspects such as tea sets, tea ceremony, tea art, and tea production. For the vast majority of tea leaves, the taste of the tea soup will become bitter and astringent due to long-term soaking, and the aroma will be lost, so that the fresh fragrance of the tea cannot be truly smelled and the mellow flavor of the tea cannot be tasted. Therefore, tea-water separation is a key link that cannot be ignored when drinking tea.

[0003] For the convenience of carrying and timely drinking, people use tea-water separation cups more frequently. A filtering container is placed in the cup. First, the tea leaves are placed in the container. When hot water is added, the water and the tea come into contact for a moment to extract the components in the tea leaves. When drinking, the tea leaves are separated from the tea soup. For example, the filtering container is directly taken out of the cup, or under the action of gravity, the tea soup flows out from the through holes on the outer periphery of the container and is separated from the tea leaves.

[0004] CN209136081 discloses a separable tea-making cup, which is formed by pressing an outer tube and an inner tube. An inwardly concave annular groove is pressed at the lower part of the inner tube. The filter mesh is fixedly connected with a fixed sleeve. A push rod is inserted into the fixed sleeve. An annular boss is provided on the push rod and at the lower end of the fixed sleeve. The annular boss is smaller than the inner diameter of the lower part of the fixed sleeve and is in clearance fit with the fixed sleeve. A spring is sleeved above the annular boss. The upper end of the push rod is provided with a thread, and the push rod passes through the fixed sleeve and the sealing piece and is fixedly connected by a nut. The upper end of the cup body is connected with a top cover in cooperation with a threaded port, and the lower end is connected with a bottom cover in cooperation with a threaded port. When in use, the base is rotated counterclockwise, and the lifting shaft will rise with the lifting nut to drive the seal to open. When the base is rotated clockwise, the lifting shaft descends with the lifting nut, and the sealing piece closes accordingly.

[0005] When the base rotates relative to the cup lid body, if the rotation is smooth, a seal cannot be provided, resulting in poor sealing effect and easy leakage. If a seal is provided, the sealing performance can be improved, and the problem of leakage can be overcome. However, interference occurs when these components move relative to each other, and the rotation is not smooth. Summary of the Invention

[0006] An object of the present invention is to provide a rotation mechanism that can still maintain a good sealing state when two components rotate relative to each other and can rotate smoothly within a range of 360°.

[0007] Another object of the present invention is to provide a cup lid that has good sealing characteristics and can rotate smoothly within a range of 360° when two components on it rotate.

[0008] Another object of the present invention is to provide a drinking cup, which has good sealing characteristics and can rotate smoothly within a 360° range, improving the user experience during the process of separating tea from water.

[0009] A rotating mechanism includes

[0010] a first component that rotates when a force is applied;

[0011] a second component that rotates relative to the first component and includes a first assembly groove;

[0012] a third component that is disposed in the first assembly groove, is assembled with the second component, rotates relative to the second component, and is stationary relative to the first component;

[0013] a seal that is assembled on the third component and contacts the first component.

[0014] To facilitate the implementation of rotation and improve the sealing effect, the third component is annular, and its inner diameter is smaller than the outer diameter of the second component.

[0015] Another type of third component includes a first surface, a second surface, a third surface, and a fourth surface. Along the axial direction of the third component, the second surface and the fourth surface are respectively located above and below the axial direction, and the first surface and the third surface are distributed along the radial direction of the third component, and the distance from the first surface to the axis of the third component is smaller than the distance from the third surface to the axis of the third component.

[0016] To facilitate the implementation of rotation and improve the sealing effect, a first arm is provided on the first surface, a second arm is provided on the second surface, and a third arm is provided on the fourth surface. The first arm, the second arm, and the third arm respectively contact the first assembly groove, and the contact positions do not overlap.

[0017] To facilitate the implementation of rotation and improve the sealing effect, a second assembly groove is further provided on the third surface, and the shape of the groove body is coordinated with the outer shape of the seal, so that the second assembly groove adapts to the seal and the seal is placed in the groove body.

[0018] Applying the rotating mechanism of the present invention to the cup lid can enable the cup lid to facilitate the purpose of separating tea from water. For example: The second component is assembled as part of the cup lid at the cup mouth of the cup body.

[0019] When manufacturing a drinking cup, such as a tea-water separation cup, using the cup lid provided by the present invention is more convenient for implementing solid-liquid separation and still can maintain a good sealing effect.

[0020] Beneficial effects achieved by the technical solution of the present invention:

[0021] When the two components of the rotating mechanism of the present invention rotate relative to each other, a good sealing effect can still be maintained, the liquid will not leak out, and the rotation is smooth, and the two components will not interfere with each other. The drinking cup adopting such a rotating mechanism is more convenient for solid-liquid separation, and the experience is significantly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments of the present invention are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.

[0027] Figure 1 is a schematic diagram of an embodiment of the rotating mechanism of the present invention, Figure 2 is Figure 1 a schematic diagram of the rotating mechanism shown from another angle. As Figure 1 and Figure 2 shown, the rotating mechanism of this embodiment includes a first component 100, a second component 200, a third component 300, and a fourth component 400. The first component 100 rotates relative to the second component 200 after receiving an external force, and the third component 300 rotates relative to the second component 200 and is stationary relative to the first component 100. In this example, the second component 200 includes a first assembly groove 210, and the third component 300 is assembled with the first assembly groove 210. The sealing member 400 is made of rubber, polyester, etc., and is in interference fit with the first component 100 so that the third component 300 remains relatively stationary with respect to the first component 100.

[0028] For the convenience of rotation implementation and to improve the sealing effect, in this embodiment, the third component 300 is annular, and its inner diameter is smaller than the outer diameter of the second component 200. For ease of assembly, a sharp cutting tool can be used to form an axially two-sided flat (for example, the surface roughness Ra is less than 0.1) and jointed cutting surface. Figure 3 It is a schematic cross-sectional view of an embodiment of the third component in the rotation mechanism of the present invention, as Figure 3 shown, the third component 300 includes a first surface 310, a second surface 320, a third surface 330, and a fourth surface 340. Along the axis of the third component 300, the second surface 320 and the fourth surface 340 are respectively located above and below the axis, and the first surface 310 and the third surface 330 are distributed along the radial direction of the third component 300, and the distance from the first surface 310 to the axis of the third component 300 is less than the distance from the third surface 330 to the axis of the third component 300.

[0029] A first arm 311 is provided on the first surface 310, a second arm 321 is provided on the second surface 320, and a third arm 341 is provided on the fourth surface 340. Along the axis of the second component 200, the second arm 321 and the fourth arm 341 are respectively in contact with the upper and lower sides of the groove body, and the third arm 341 is in contact with the bottom of the groove. A second assembly groove 331 is also provided on the third surface 330, and the shape of the groove body is coordinated with the outer shape of the seal 400 so that the second assembly groove 331 can accommodate the seal 400 and place the seal 400 in the groove body. Specifically, when the outer shape of the cross-section of the seal is circular or elliptical, the second assembly groove 331 must include a groove body with an arc to place the seal 400 in the groove body. When the outer shape of the cross-section of the seal is polygonal, the second assembly groove 331 must include a groove body with a polygon to place the seal 400 in the groove body.

[0030] Apply the rotation mechanism of this embodiment to a cup lid. For example, assemble the second component 200 as a part of the cup lid at the cup mouth of the cup body. When rotating the first component 100, it can move relative to the second component 200 and simultaneously drive the screw 500 to rotate to implement solid (such as tea leaves) - liquid (such as water or tea) separation. Figure 4 It is a schematic cross-sectional view of an embodiment of the application of the rotation mechanism of the present invention to the assembly of a cup lid and a cup body, as Figure 4As shown, as the first component 100 rotates clockwise or counterclockwise (the rotation direction is determined by the thread of the screw rod 500), the screw rod 500 is driven to rotate and push the ejector rod 600 to apply a force to the moving rod 700, causing the sealing mechanism 800 fixed on the moving rod 700 to displace, enabling water to flow downward and achieving solid-liquid separation. When the first component 100 rotates in the reverse direction, the force applied to the moving rod 700 is removed, the sealing mechanism 800 resets to implement sealing, and the water no longer flows, allowing liquid to be added continuously, such as making tea. During this period, the first component 100 and the second component 200 rotate smoothly, and the two components do not interfere with each other, significantly improving the operation experience.
