Abstract

The utility model relates to a filter screen capable of making concentrated coffee, which comprises a filter screen body, a funnel, an isolated net, a sealing ring and a spring, wherein the filter screen body is of a cylinder shape, and the bottom is provided with a plurality of fine meshes; the funnel is sheathed at the head part of the filter screen body; the sealing ring is padded at the inner end surface of the funnel and is in an oppression contact form with the end surface at the mouth part of the filter screen body; a round pipe-shaped holder part in the middle of the isolated net is sheathed in a hole at the lower part of the funnel; one end of the spring supports at the lower side of the funnel, and the other end supports at the upper side of the isolated net. The utility model can make concentrated coffee, and is mainly matched with an ordinary dripping type coffee pot or a coffee cup and can also be used alone. The utility model has the advantages of low cost, convenient operation and high speed for filtering.

Description

A kind of filter screen that can make espresso

Technical field

The utility model relates to a kind of filter screen that can make espresso, and main supporting water clock formula coffee pot or the coffee cup of being used for also can use separately, is a kind of miscellaneous small appliances.

Background technology

Present Coffee screen net coffee powder when infusing coffee floats in the water, just the hot water that adds is with after certain density coffee water mixes, the utility dissolving of coffee powder slowly, some filter screen periphery has a large amount of apertures, just the hot water that adds without with the abundant mixed dissolution of coffee powder just from the side filter screen aperture flow out, the caffeinated water who leaches is dense inadequately, some filter screen only has mesh in the bottom, but the rate of filtration is slow, and the time of cost is long, and effect is bad.

Summary of the invention

For addressing the above problem, the purpose of this utility model is that coffee powder can not be floated in the water when punching out coffee, and the water that adds must fully with after coffee powder mixes filter out, and manufacturing speed is very fast, can make denseer coffee.

The purpose of this utility model is achieved in that and comprises strainer body, funnel, filter, sealing ring, spring.Strainer body is cylindrical, a lot of fine and closely woven mesh are arranged at the bottom, and head has screw thread, and funnel is enclosed within the strainer body head, screw with the screw thread of strainer body head, sealed loop-pad is compressing with the oral area end face of strainer body and contacts shape at the inner face of funnel, makes and forms an airtight space between strainer body and the funnel, the shank of the pipe shape in the middle of the filter is enclosed within the hole of funnel bottom, stay little clearance to slide up and down flexibly, spring one end withstands on below the funnel, and the other end withstands on above the filter.During use, the coffee powder of packing in strainer body, filter are pressed in coffee powder the bottom of strainer body automatically under the pressure of spring, prevent that coffee powder from floating, and water just must fully just can flow out through coffee powder.Because funnel is on the top of strainer body, so the water on the funnel forms pressure naturally for the strainer body bottom, the height of funnel is high more, and this hydraulic pressure is just big more, and the rate of filtration is just fast more.Suitable height just can the quick Fabrication espresso.

The beneficial effects of the utility model are: can make things convenient for and make espresso fast and effectively, safety, simple, cost is low.

Description of drawings

Fig. 1 is a vertical section of the present utility model structural map.

The specific embodiment

As shown in Figure 1, the utility model comprises strainer body (1), funnel (2), filter (5), sealing ring (3), spring (4).Strainer body (1) is cylindrical, and a lot of fine and closely woven mesh are arranged at the bottom, and head has screw thread, and funnel (2) periphery has internal thread to screw at strainer body (1) head; Sealing ring (3) pad is compressing with the oral area end face of strainer body (1) and contacts shape at the inner face of funnel (2), makes and forms an airtight space between strainer body (1) and the funnel (2); The shank of the pipe shape in the middle of the filter (5) is enclosed within the hole of funnel (2) bottom, stay little clearance to slide up and down flexibly, little shoulder is arranged respectively at the bottom in filter (5) head and funnel (2) hole, and interference fit connects together these two parts and can not separate easily mutually; Spring (4) one end items are below funnel (2), and the other end withstands on above the filter (5); Funnel (2), filter (5), sealing ring (3), these four parts of spring (4) connect together and do not separate easily, become a sub-assembly.

The utility model course of work is as follows:

During use, the coffee powder of packing in strainer body (1) puts this sub-assembly then, screws to get final product.Filter (5) can be pressed in coffee powder the bottom of strainer body (1) automatically under the pressure of spring (4), prevent that coffee powder from floating. and the elastic force of spring (4) is the consumption of transfer adaptation coffee powder automatically.The hot water that adds from funnel (2) flows to above the filter (5) through funnel (2), because the space between funnel (2) and the filter (5) seals, so, water on the funnel (2) is delivered to above the filter (5) for the pressure that strainer body (1) bottom forms naturally, the position of funnel (2) is high more, this hydraulic pressure is just big more, and it is just fast more that water sees through the speed of coffee powder, the flow of crossing coffee pot when caffeinated water's flow is fast just can with supporting use of water clock formula coffee pot.The water coffee powder of under this pressure, fully flowing through, because water is the time marquis of the coffee powder of flowing through, utility dissolving back flows out from the bottom of strainer body (1), coffee concentration is low in the hot water that the back adds, the easier further dissolving fast of utility that makes in the coffee powder, the coffee of squeezing out more fully so just can be produced concentrated coffee.

As shown in Figure 1, filter (5) is disc, shank is the pipe shape of hollow, inside diameter is approximately greater than 4 millimeters, root is porose, and perpendicular to its axle center, sectional area is approximately greater than the sectional area in the hole of 4 millimeters of diameters, guarantee the flow of the flow of water greater than coffee pot, can with the supporting use of water clock formula coffee pot.

As shown in Figure 1, strainer body (1) is columnar, only in the bottom fine and closely woven mesh is arranged, and guarantees just to flow out after hot water must flow through coffee powder, and the outer surface of head has screw thread to screw sealing that can be convenient and reliable with funnel (2).

Claims

1. the filter screen that can make espresso comprises strainer body (1), funnel (2), filter (5), sealing ring (3), spring (4).Strainer body (1) is cylindrical, and a lot of fine and closely woven apertures are arranged at the bottom, and the head periphery has external screw thread; Funnel (2) periphery has internal thread to screw at strainer body (1) head; The shank of the pipe shape in the middle of the filter (5) is enclosed within the hole of funnel (2) bottom; Spring (4) one ends withstand on below the funnel (2), and the other end withstands on above the filter (5).
