Description

Filtrate appliance and water cup

Technical Field

The invention relates to a tool for separating substances, in particular to an appliance for separating solid and liquid, which accelerates the speed of solid and liquid separation and improves the separation efficiency.

Background

Tea is an important component of Chinese culture, and therefore, tea making drives the development of tea sets, tea ceremony, tea art, tea making and the like. Most of tea leaves can cause bitter taste of tea water and loss of aroma due to long-time soaking, so that the faint scent of the tea cannot be truly smelled and the mellow charm of the tea cannot be really tasted, and therefore, tea water separation is a key link which is not negligible when people drink the tea.

In order to facilitate carrying and drinking in time, people often use tea-water separation cups, a filtering container is placed in each cup, tea is firstly placed in the container, and when hot water is added, water is contacted with tea, so that components in the tea are extracted. When the tea is drunk, tea leaves are separated from tea water, for example, the filtering container is directly taken out from the cup, or the tea water flows out from the through holes at the periphery of the container under the action of gravity so as to be separated from the tea leaves.

CN209136081 discloses a separate tea making cup, which is formed by pressing an outer tube and an inner tube, wherein the lower part of the inner tube is pressed with an inward concave annular groove. The filter screen piece is fixedly connected with the fixed sleeve, a push rod is inserted in the fixed sleeve, an annular boss is arranged at the lower end of the fixed sleeve on the push rod, 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, and a spring is sleeved on the annular boss. The upper end of the ejector rod is provided with a thread, and the ejector rod passes through the fixed sleeve and the sealing piece to be fastened and connected through a screw cap. The upper end of the cup body is connected with a top cover in a matched manner with the threaded opening, and the lower end is connected with a bottom cover in a matched manner with the threaded opening. When the sealing device is used, the base is rotated anticlockwise, and the jacking shaft can ascend along with the jacking nut so as to drive the sealing device to be opened. The base is rotated clockwise, the jacking shaft descends along with the jacking nut, and the sealing piece is closed along with the jacking nut.

Because the cup body adopts two superposed chambers, one chamber is used for mixing the solid and the liquid, the liquid is favorable for extracting substances in the solid, and the extracting liquid and the solid are separated into the other chamber after the sealing sheet is opened. Because the height of the cup cover is limited (about 32mm generally), the travel of the ejector rod assembled by threads is short, so that an opening generated after the sealing piece is displaced is small, the extracting solution is difficult to separate from the solid quickly, and the extracting solution can slowly flow into the other cavity only by manually tilting the cup body (about 60 degrees).

When using a high temperature liquid, the tilting of the hand-held cup is required, and the skin may be burned by the heat released from the liquid. If the liquid is cooled and then subjected to solid-liquid separation, the faint scent and mellow charm of the tea cannot be experienced. Therefore, the safety and convenience of solid-liquid separation, especially tea water separation operation, have yet to be improved.

Detailed Description

The technical scheme of the present invention is described in detail below with reference to the accompanying drawings. The embodiments of the present invention are only for illustrating the technical scheme of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical scheme of the present invention, which is intended to be covered by the scope of the claims of the present invention.

Fig. 1 is an exploded view of an embodiment of the filtrate vessel of the present invention, and fig. 2 is a schematic view of the filtrate vessel of fig. 1 at another angle. As shown in fig. 1 and 2, the filtrate instrument of the present embodiment includes a rod member 100, a filter member 200, a sealing member 300, and a flow guide member 400. The filter member 200 is provided with a through-hole 210 and an opening (not shown), the through-hole 210 to perform solid and liquid separation, and the collected liquid is discharged from the opening. The sealing member 300 is provided at the opening of the filtering member 200, includes a first upstream surface 310, i.e., a surface facing the direction of the water flow, and is impacted by the water flow. One end of the rod 100 is disposed at the center of the sealing member 300, and is connected to the sealing member 300 to push the sealing member 300 to move. For example, when the liquid is leached out from the solid, the sealing member 300 is assembled with the opening of the filter member 200 to seal the solid from flowing out. When extraction is completed, and it is desired to separate the solids from the liquid, a force (e.g., pressure, pushing or pulling) is applied to the rod 100, and the sealing member 300 is moved and removed from the opening of the filter member 200, so that the liquid flows out. At this time, when the movement amount of the seal member 300 is small, a partial vacuum phenomenon is generated, and the liquid cannot smoothly flow out, and it is necessary to tilt the filter. However, the rod 100 is not necessarily required, and other means, such as applying an external magnetic field to the sealing member 300 or ultrasonic vibration, can also be used to release the sealing member 300 from the opening of the filter member 200.

For this purpose, in the present embodiment, the flow guide member 400 is provided on the sealing member 300. Fig. 4 is a schematic view of an embodiment of a sealing member with a flow directing member, and fig. 5 is a schematic view of the member shown in fig. 4 at another angle. As shown in fig. 4 and 5, the flow guiding member 400 is disposed on the first water facing surface 310, and one end thereof is adjacent to the rod member 100 and gradually decreases in gradient toward the edge of the sealing member 300. In this embodiment, the flow guiding component 400 is a slope body, the slope height near the rod is 2 mm-3 mm, the direction towards the edge of the sealing component is fanned and spread, and the slope gradually decreases. The flow guiding component 400 includes a second upstream surface 410, which is a curved surface and covers the first upstream surface 310 with an area greater than 10%.

Thus, when the sealing member 300 moves and is withdrawn from the opening of the filtering member 200, the partial vacuum phenomenon is improved and eliminated, and the liquid smoothly flows out from the outlet, without tilting the filtering means, so that solid-liquid separation can be achieved. When the filtrate appliance of the embodiment is used for a water cup, the cup body is not required to be held by hands to incline when tea water separation is carried out, water flow can be enabled to flow rapidly only by pressing the rod piece 100, hands are prevented from being burnt by hot water, and safety is improved.

In order to increase the speed of fluid flowing out of the openings through the through holes, in this embodiment, the filter element further includes a support 220 and a drainage member 230, and the support is disposed on the outer layer of the drainage member. Fig. 3 is a top view of an embodiment of the filtrate vessel according to the present invention, referring to fig. 1, as shown in fig. 3, the drainage member 230 is in the shape of a ring, and a plurality of drainage holes 231 are provided on the annular surface. Of these drainage holes 231, centers including at least 3 drainage holes are connected to form an arc. The drainage holes 231 are communicated by the slotted holes 232 to form 1 row of drainage areas. At least 1 drainage area is arranged on the annular surface, the drainage areas transversely span between the inner edge 233 and the outer edge 234 of the drainage piece 230, a plurality of drainage areas are sequentially arranged on the annular surface, and after liquid passes through the drainage areas, vortex is gradually formed, so that the overall flow speed of the liquid is accelerated.

In addition, the upper side surface of the supporting piece is higher than the annular surface by 0.3 mm-1 mm, and the lower side surface of the supporting piece is higher than the annular surface by 0.3 mm-1 mm, so that the liquid can form vortex through the drainage piece 230, and the liquid flowing speed is accelerated.

The filtrate appliance is used for the water cup, can meet the requirement that the height of the cup cover (for example, 28-32 mm) is limited, and improves the convenience of solid-liquid separation. And the generation of partial vacuum is eliminated, so that water flow (such as extracting solution) can flow outwards from the opening, and the solid-liquid separation efficiency is improved.

Because the sealing component is opened, partial vacuum can be avoided, water flow outflow is smoother, so that the cup body is not required to be inclined, tea water separation can be realized, the situation that the cup body is burnt by hot water due to holding by hand is avoided, the use safety of the cup is improved, the fragrance of tea can be truly smelled, the mellow wine of the tea can be tasted, and the tea drinking experience of the cup is remarkably improved.
