Description

Technical Field

[0001] The utility model relates to a tea-making utensil, more specifically a filter for making tea in a teacup. Background Art

[0002] When brewing tea in a teacup, a strainer is needed to separate the tea from the water, keeping the tea in the cup to prevent the tea leaves and water from flowing out together.

[0003] In order to solve the above technical problems, Chinese utility model patent CN205814120U discloses a shadowless filter glass cup, including a cup body and a filter screen. The filter screen is circular and has a plurality of holes. Three spring pins are evenly spaced at the edge of the filter screen, and a handle is provided in the middle of the filter screen. The spring pin of the utility model has a telescopic function. When placed in the inner wall of the cup body, the spring pin is compressed. When pushed to the groove on the cup body, the spring pin returns to a natural state and is stuck in the groove.

[0004] The technical problem is that the filter is stuck at the mouth of the cup when in use. During the process of adding water into the cup, a water film is easily formed on the surface of the filter, making it difficult for the gas in the cup to be discharged and for the water above to flow down, resulting in slow water drainage. Since the filter is relatively close to the mouth of the cup, if water is added a little faster, the added water is easy to overflow from the mouth of the cup due to the slow drainage. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a filter for brewing tea in a teacup. During the water filling process of the filter, the gas in the cup is easy to be discharged and it is not easy to form a water film on the filter screen surface. The gas in the cup is easy to be discharged, the water filling is fast, and the added water will not overflow from the cup mouth.

[0006] In order to solve the above technical problems, the utility model adopts the following technical means:

[0007] A filter for brewing tea in a teacup comprises a filter body, wherein the filter body is provided with a clamping protrusion matched with the inner wall of the cup body, the clamping protrusion enables the filter body to be clamped in the cup body to prevent the filter body from sliding, the filter body is provided with filtering holes and air holes, and the air holes are provided with an air tube extending upward.

[0008] Compared with the prior art, the utility model adopting the above technical solution has the following outstanding features:

[0009] This technical solution sets a convex clamp, which cooperates with the inner wall of the cup body to limit the filter body; through the filter holes and air holes set on the filter body, the filter holes are used to filter tea and water, and the air holes are used to ventilate during the water permeation process, which is convenient for filling water into the cup; the air holes are provided with an upwardly extending air tube, and during the water filling process, water flows into the cup through the filter holes, and at the same time, the air in the cup is discharged outward through the air tube, which speeds up the smooth flow of water into the cup. Due to the setting of the air holes and the air tube, the gas in the cup is easy to be discharged, and it is not easy to form a water film on the surface of the filter body. The gas in the cup is easy to be discharged, the water is discharged quickly, and the added water will not overflow from the cup mouth.

[0010] It should be noted that if the card cam is made of titanium material, since titanium has weak elastic deformation ability, a silicone sleeve or a silicone layer needs to be bonded on it, and the silicone sleeve, silicone layer and the inner wall of the cup form friction to prevent sliding.

[0011] Further preferred technical solutions are as follows:

[0012] The filter body is circular.

[0013] The cup is generally round, so the filter body is also chosen to be round.

[0014] The filter body is in the shape of a spherical shell with a concave middle portion.

[0015] In the above arrangement, the center is the lowest, which facilitates the convergence of water to the center when adding water. The filter body is not flat, and the water on its surface is flowing. The flowing water is not easy to form a film on the surface of the filter body, further accelerating the seepage of water.

[0016] An annular plane is arranged at the edge of the filter body.

[0017] By providing the annular plane, the filter body and the annular convexity in the cup body are more stably matched, and the filter body is not easy to slide down.

[0018] An annular clamping cylinder is arranged on the bottom surface of the filter body, and a clamping protrusion is arranged on the outer side surface of the annular clamping cylinder.

[0019] By providing the annular clamp, the annular clamp makes the cooperation between the component and the inner wall of the cup body more stable.

[0020] The diameters of the filter body and the annular cartridge can be set according to the different conditions of the inner wall of different cups. For example, if there is a protrusion in the cup, the diameter of the filter body is larger than the diameter of the circle where the protrusion on the annular cartridge is located; if there is no protrusion in the cup, the diameter of the filter body must be smaller than the diameter of the circle where the protrusion on the annular cartridge is located.

[0021] A planar convex ring is arranged on the bottom surface of the filter body, one surface of the planar convex ring is welded or riveted to the filter body, and a convex is connected to the other surface of the planar convex ring.

[0022] The flat-shaped snap ring is easy to process and can be used as a connecting component to facilitate setting of the snap ring.

[0023] The clamping protrusion is provided with a welding portion or a riveting portion, and the clamping protrusion is connected to the filter body by welding or riveting.

[0024] The clamping protrusion is connected to the filter body by welding or riveting, so that the two components are stably and firmly connected.

[0025] The filter body is provided with a folding portion, and the folding portion has a portion protruding outwards to form a clamping convexity.

[0026] The protruding part of the folded part is used to form a convex block, so that the device can be formed in one piece by stamping a plate. When the diameter of the folded part is smaller than the diameter of the filter body, it is convenient to install it in the cup.

[0027] The filter holes on the filter body have different apertures, and the apertures of the filter holes increase from the edge to the center.

[0028] The above-mentioned setting of different pore sizes is conducive to the flow of water from small filter holes to large filter holes in the filter body, further preventing the formation of a water film on the surface of the filter body.

[0029] The air-permeable cylinder and the filter body are connected by threaded connection, welding or riveting.

[0030] The air cylinder and the filter body can be connected by any common component connection method. BRIEF DESCRIPTION OF THE DRAWINGS
