Description

Technical Field

[0001] The invention relates to a tool for implementing material separation, and in particular to an apparatus for implementing solid-liquid separation, which accelerates the speed of solid-liquid separation and improves separation efficiency. Background Art

[0002] Tea is an important part of Chinese culture. Therefore, tea brewing has driven the development of tea sets, tea ceremony, tea art, tea making, etc. Most tea leaves will become bitter and lose their aroma due to long-term soaking, and it is impossible to really smell the fragrance of tea and taste the mellow charm of tea. Therefore, the separation of tea and water is a key link that cannot be ignored when drinking tea.

[0003] In order to facilitate carrying and timely drinking, people often use tea-water separation cups. A filter container is placed in the cup, and tea leaves are placed in the container first. When hot water is added, the water and tea come into contact for a moment to extract the ingredients in the tea leaves. When drinking, the tea leaves are separated from the tea water, for example, the filter container is directly taken out of the cup, or the tea water flows out from the through holes on the outer periphery of the container under the action of gravity and is separated from the tea leaves.

[0004] CN209136081 discloses a separate tea brewing cup, which is formed by pressing an outer tube and an inner tube together, and the lower part of the inner tube is pressed with an inwardly concave annular groove. The filter mesh is tightly connected to the fixed sleeve, and a push rod is inserted in 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 with the fixed sleeve. A spring is mounted on 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 is tightly connected with the sealing plate by a nut. The upper end of the cup body is connected with a top cover in cooperation with the threaded opening, and the lower end is connected with a bottom cover in cooperation with the threaded opening. When in use, the base is rotated counterclockwise, and the lifting shaft will rise with the lifting nut, thereby driving the seal to open. The base is rotated clockwise, and the lifting shaft descends with the lifting nut, and the sealing plate is closed accordingly.

[0005] Since the cup body has two stacked chambers, one of which is used for mixing solids and liquids, it is beneficial for the liquid to extract substances from the solids; after opening the sealing sheet, the extract is separated from the solids and enters the other chamber. Due to the height of the cup cover (generally about 32mm), the threaded push rod has a short stroke, so the opening created by the displacement of the sealing sheet is small, and it is difficult for the extract to be quickly separated from the solids. The cup body needs to be tilted manually (about 60°) to allow the extract to slowly flow into the other chamber.

[0006] When using high-temperature liquid, you need to hold the cup and tilt it, and your skin may be burned by the heat released by the liquid. If you wait for the liquid to cool before separating the solid and liquid, you will not be able to experience the fragrance and mellow flavor of the tea. Therefore, the safety and convenience of solid-liquid separation, especially tea-water separation, still needs to be improved. Summary of the invention

[0007] One object of the present invention is to provide a filtration device to increase the speed at which liquid flows out of the filter and accelerate the solid-liquid separation speed.

[0008] Another object of the present invention is to provide a filtration device for a tea-water separation cup, which can enable the solid and liquid in the cup to be quickly separated when the cup body is upright, thereby improving the convenience of solid-liquid separation.

[0009] Another object of the present invention is to provide a water cup for separating tea and water, especially a water cup that needs to be used to make tea with hot water. The tea and water can be separated without tilting the cup body, so as to avoid burns to hands by hot water and improve safety.

[0033] The technical solution of the present invention is described in detail below with reference to the accompanying drawings. The embodiments of the present invention are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.

[0034] Figure 1 An exploded view of an embodiment of the filtration apparatus of the present invention, Figure 2 for Figure 1 The schematic diagram of the filtration apparatus from another angle is shown. Figure 1 and Figure 2 As shown, the filtration device of this embodiment includes a rod 100, a filter component 200, a sealing component 300 and a flow guide component 400. The filter component 200 is provided with a through hole 210 and an opening (not shown), and the through hole 210 is used to separate solids and liquids, and the collected liquid is discharged from the opening. The sealing component 300 is arranged at the opening of the filter component 200, and includes a first water-facing surface 310, that is, a surface facing the flow direction of the water flow and being impacted by the water flow. One end of the rod 100 is arranged at the center of the sealing component 300, connected to the sealing component 300, and pushes the sealing component 300 to move. For example: when the liquid implements leaching extraction on the solid, the sealing component 300 is assembled with the opening of the filter component 200 to implement sealing and prevent the liquid from flowing out. When the leaching extraction is completed and the solid and the liquid need to be separated, a force (such as pressure, thrust or pulling force) is applied to the rod 100, and the sealing component 300 moves and escapes from the opening of the filter component 200, so that the liquid flows out. At this time, when the movement of the sealing component 300 is small, a local vacuum phenomenon is formed, and the liquid cannot flow out smoothly, and the filter needs to be tilted. However, the rod 100 is not necessary, and other means can also achieve the sealing component 300 to escape from the opening of the filter component 200, such as: applying an external magnetic field to the sealing component 300, or ultrasonic vibration and other means.

[0035] To this end, in this embodiment, a flow guide component 400 is provided on the sealing component 300 . Figure 4 is a schematic diagram of an embodiment of a sealing component with a flow guide component, Figure 5 for Figure 4 A schematic diagram of another angle of the components shown. Figure 4 and Figure 5 As shown, the flow guide component 400 is arranged on the first water-facing surface 310, one end of which is close to the rod 100, and the slope gradually decreases towards the edge of the sealing component 300. In this embodiment, the flow guide component 400 is a slope, the slope height near the rod is 2mm to 3mm, and it spreads in a fan shape towards the edge of the sealing component, and the slope gradually decreases. The flow guide component 400 includes a second water-facing surface 410, which is a curved surface, covering the first water-facing surface 310, and the area is greater than 10%.

[0036] Thus, when the sealing component 300 moves and escapes from the opening of the filter component 200, the local vacuum phenomenon is improved and eliminated, and the liquid flows out smoothly from the outlet without tilting the filter device, thereby achieving solid-liquid separation. When the filtration device of this embodiment is used for a water cup, when implementing tea-water separation, there is no need to hold the cup body to tilt the cup body. The water can flow quickly by pressing the rod 100, which also prevents both hands from being burned by hot water, thereby improving safety.

[0037] In order to increase the speed at which the fluid is discharged through the through holes and converges at the opening, in this embodiment, the filter component further includes a support member 220 and a guide member 230, and the support member is arranged on the outer layer of the guide member. Figure 3 FIG. 1 is a top view of an embodiment of the filtration device of the present invention, see Figure 1 ,like Figure 3 As shown, the drainage member 230 is annular, and a plurality of drainage holes 231 are arranged on the annular surface. Among these drainage holes 231, at least three drainage holes are connected at their centers to form an arc. Each drainage hole 231 is connected by a slot 232 to form a row of drainage areas. At least one drainage area is arranged on the annular surface, and the drainage area spans between the inner edge 233 and the outer edge 234 of the drainage member 230. The plurality of drainage areas are arranged in sequence on the annular surface. After the liquid passes through these drainage areas, a vortex is gradually formed, which speeds up the overall flow rate of the liquid.

[0038] In addition, the upper side surface of the support member is 0.3 mm to 1 mm higher than the annular surface, and the lower side surface of the support member is 0.3 mm to 1 mm higher than the annular surface, which further facilitates the liquid to form a vortex through the guide member 230 and accelerates the flow rate of the liquid.

[0039] The filtration device of this embodiment is used in a water cup, which can meet the requirement of limited cup cover height (for example, 28 mm to 32 mm), improve the convenience of solid-liquid separation, eliminate the occurrence of local vacuum, facilitate the flow of water (such as extract) outward from the opening, and improve the efficiency of solid-liquid separation.

[0040] After the sealing component is opened, local vacuum is avoided and water flows out more smoothly. Therefore, there is no need to tilt the cup body to achieve tea and water separation, avoiding burns from hot water due to holding the cup body, improving the safety of using the water cup, and allowing people to truly smell the fragrance of the tea and taste the mellow flavor of the tea, significantly improving the tea drinking experience of the water cup.
