Description

Technical Field

[0001] The utility model relates to a filter screen without tea residue. Background Art

[0002] my country's tea culture has a long history. When brewing tea, tea sets are usually used. The tea sets contain filters. After putting tea leaves into the filter and pouring hot water, the tea can be discharged into the teapot through the water holes on the filter, which is convenient for users to pour out the tea and separate the tea leaves. The filters currently on the market have a flat bottom structure. After the tea leaves are poured out, they easily cover the water holes at the bottom of the filter, causing some tea to accumulate at the bottom of the filter and fail to be discharged. When the user removes the filter, the tea will be discharged from the water holes on the side of the filter, causing the tea table to be wetted by the tea.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The utility model aims to overcome the above problems and provides a filter screen without tea residue, which solves the problem that tea accumulates at the bottom and cannot be discharged smoothly.

[0005] To achieve the above-mentioned purpose, the utility model provides a filter screen without tea residue, which includes a cylinder and a bottom shell, both of which are provided with a water-passing structure, the upper and lower ends of the cylinder are open, the upper end of the bottom shell has a first annular connecting wall, the lower end opening of the cylinder has a second annular connecting wall, the second annular connecting wall is sleeved on the outside of the first annular connecting wall and welded and fixed thereto, the bottom end of the bottom shell is a plane, and an arc-shaped transition structure is provided between the plane of the bottom end and the first annular connecting wall.

[0006] In one or more embodiments, the height of the first annular connecting wall is 5MM-15MM.

[0007] In one or more embodiments, the water flow structure is composed of a plurality of water flow holes, and the water flow holes are circular in shape.

[0008] In one or more embodiments, the upper end edge of the cylinder is bent outward to form an annular supporting edge.

[0009] In one or more embodiments, a handle is provided near the upper end of the cylinder, and both ends of the handle pass through the cylinder and are rotatably connected to the cylinder.

[0010] In one or more embodiments, the cylinder and the bottom shell are both made of 304 stainless steel or 316 stainless steel.

[0011] Compared with the background technology, the utility model has the following effects: the filter screen is composed of a cylinder and a bottom shell, and by arranging a plane and an arc-shaped transition structure on the bottom shell, tea leaves will accumulate on the plane, and the water-passing structure on the arc-shaped transition structure helps to drain the tea and avoid tea accumulation.

[0015] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0016] Please see attached Figure 1-3 The present application provides a filter screen without tea residue, which includes a cylinder 1 and a bottom shell 2. Both the cylinder and the bottom shell are provided with a water passing structure. The water passing structure is composed of a plurality of water passing holes 5. The water passing holes are circular in shape, and the diameter is preferably 1MM-3MM. The upper and lower ends of the cylinder 1 are open, and the upper end of the bottom shell 2 has a first annular connecting wall 3, and the lower end opening of the cylinder 1 has a second annular connecting wall 4. The second annular connecting wall is sleeved on the outer side of the first annular connecting wall and is welded and fixed thereto. The structure can enhance the structural strength of the connection between the cylinder and the bottom shell and the sealing after the connection. The bottom end of the bottom shell 2 is a plane 21, and an arc-shaped transition structure 22 is provided between the plane of the bottom end and the first annular connecting wall 3. When in use, the tea leaves will accumulate on the plane after being flushed, and the tea will flow around and finally be discharged through the water passing holes on the arc structure, avoiding the problem of poor drainage caused by the tea leaves covering the bottom surface of the bottom shell.

[0017] The height of the first annular connecting wall 3 is 5MM-15MM, preferably 10MM, to ensure that the first annular connecting wall has a certain height and is welded and fixed to the second annular connecting wall.

[0018] The upper end edge of the cylinder 1 is bent outward to form an annular support edge 6, which can abut against the mouth of the teapot to prevent the filter from entering the teapot completely and causing difficulty in removing it.

[0019] The barrel 1 is provided with a handle 7 near the upper end, with the help of which the user can easily remove the filter and avoid burns. Both ends of the handle pass through the barrel 1 and are rotatably connected to the barrel. When brewing tea, the handle is rotated to make it stick to the inner wall of the barrel to avoid affecting the user's putting in of tea.

[0020] The cylinder 1 and the bottom shell 2 are both made of 304 stainless steel or 316 stainless steel. 304 and 316 stainless steel are of food grade quality and are preferably used as the manufacturing material of the tea filter.

[0021] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
