Description

A kind of device structure that brews

A kind of device structure that brews, it is applicable to the container of manufacturing as the daily life beverage.Be daily living article.

, use a kind of special container-brew device to hold the raw material of pulverizing and add boiling water more and brew as if the manufacturing in the process of the coffee drunk, tea etc. in daily life.Afterwards, solution is separated with undissolvable solid content, obtain required beverage.Its that uses brews the device structure shown in accompanying

drawing

1,2,3 and 4 now, and it is made up of cup 5, bowl cover 3, depression bar 2, filtration piston 4.Wherein, filter piston 4 again by retainer ring 8, screen pack 9, ring spring 23 and following retaining ring 10 are formed, and use sleeve 7 to be connected with depression bar 2 with following retaining ring 10.Be installed with the double-screw bolt 13 of hollow in the central authorities of bowl cover 3, and be connected by nut 12 and bowl cover 3.In use, fill the mixing material that brews in the cup 5, put into cup 5 filtering piston 4, after covering bowl cover 3, pushing depression bar 2 makes and filters piston 4 and move down, solution 61 by screen pack 9 flow to filter piston 4 above, and undissolvable solid content 6 is hindered below filtering piston 4, makes solution obtain separating.Like this brew the isolated by filtration that device can also be used to resemble herbal liquid medicine.

But there are the following problems for the device that brews of this spline structure:

Consult attached Fig. 1 and 2 owing to filter piston 4 by retainer ring 8, screen pack 9, a plurality of parts such as ring spring 23 and following retaining ring 10 are formed, complex structure not only, and long-time use easily to produce become flexible.

In use, filtration piston 4 moves up and down and all will be subjected to the effect of liquid and wall of cup frictional resistance, after certain number of times, fixedly the ring spring 23 of screen pack 9 peripheries easily follows the string, screen pack 9 torsional deformations produce the space and make fixedly, lose the effect of filtration, thereby need often to change.

As shown in Figure 4, filter the external diameter sealing of leaning on retainer ring 8 and following retaining ring 10 between the inwall of piston 4 and cup 5.There is the gap in such sealing, particularly owing to expand with heat and contract with cold or the wearing and tearing after using certain hour, the capital is strengthened the gap, when filtration piston 4 presses down, the undissolvable solid content 6 of bottom can turn back to top by the gap, particularly separating as if in the thin raw material such as coffee, make separation not thorough.

The purpose of this utility model be invention a kind of simple in structure firmly, filter and seal the tight device structure that brews between the inwall of piston and cup.

Structure of the present utility model is shown in accompanying

With reference to accompanying

drawing

5,6,7 and 8, the device that brews described in the utility model also is made up of cup 5, bowl cover 3, depression bar 2, filtration piston 4.It filters piston 4 structure that is formed in one, and screen pack 41 is coated on the inside configuration of filtering piston 4.Filtering in the piston 4 has not had as consumable accessorys such as turns, simple in structure firm.The periphery of filtering piston 4 is a retainer ring 47, its edge is sealing lip limit 42 laterally zygomorphic, that periphery stretches out and is formed with multiple crooked cambered surface, by the inwall fitted seal of sealing lip limit 42 with cup 5, because multiple crooked cambered surface makes sealing lip limit 42 have bigger flexibility and certain radial pressure, not only sealing is reliable, and resistance is less, and has bigger wearing and tearing and compensation ability of expanding with heat and contract with cold and the ability that adapts to cup 5 internal diameter varies.Utilize the inwall fitted seal of sealing lip limit 42 and cup 5, make the utility model can be used to brew as if the so carefully beverage of raw material of coffee.There is the sleeve 43 that is threaded that is connected with depression bar 2 in the central authorities of filtering piston 4, and the screw thread by sleeve 43 middle parts that are threaded is connected with the screw thread 22 of depression bar 2 lower ends.The sleeve 43 that is threaded respectively is connected with retainer ring 47 by a radial gusset 44 up and down, in the top and bottom that are threaded between sleeve 43 and the retainer ring 47 one ring stiffener 45 is arranged respectively, in the upper and lower surface of retainer ring 47 several reinforcements 46 is arranged.Radial gusset 44 not only plays the effect of affixed retainer ring 47, and clamps screen pack 41 together with ring stiffener 45, also plays the booster action to screen pack 41, makes it can not be distorted distortion.

Shown in accompanying drawing 8A and B, bowl cover 3 be shaped as an arcuation bowl cover, have a hole cylinder 31 to extend to bowl cover 3 inside in top central authorities, be distributed with several prominent tenons 32 in bowl cover 3 outer edges bottom.Prominent tenon 32 can fasten with the chimb 55 of cup 5 oral areas, makes fastening being connected with cup 5 of bowl cover 3 energy.

The utility model is owing to adopt integrated filtration piston, screen pack is coated on and filters structure of piston inside, its periphery is a retainer ring, the edge is laterally zygomorphic, the sealing lip limit that periphery stretches out and is formed with multiple crooked cambered surface, there is the sleeve that is threaded that is connected with depression bar in the central authorities of filtering piston, the sleeve that is threaded respectively is connected with retainer ring by a radial gusset up and down, in the top and bottom that are threaded between sleeve and the retainer ring one ring stiffener plate is arranged respectively, upper and lower surface at retainer ring has several reinforcements, simple in structure firm, sealing is tight between the inwall of filtration piston and cup.

Sealing lip of the present utility model limit 42 can be shown in accompanying drawing 6B, and its multiple crooked cambered surface can be made up of three sections cambered surfaces 421,422 and 423, makes sealing lip limit 42 can be affixed on the inwall of cup 5 submissively.Multiple crooked cambered surface also can be made up of the cambered surface more than two sections or three sections.The thickness on sealing lip limit, multiple crooked cambered surface place 42 can be equal thickness, also can be the thickening degree.

Ring stiffener plate 44 of the present utility model can have more than three or three, can evenly distribute to form as " ten " font, " rice " font etc., decides as the case may be.

Cup 5 oral areas of the present utility model can be provided with a pouring mouth 51 that certain slope arranged, this not only can conveniently guide the solution 61 in the cup 5 to pour out, but also having the function of pressure release, 4 gases that can produce of push-and-pull filtration piston can be discharged on non-resistance ground when making work.

Cup 5 intracavity diameters of the present utility model can be the slightly little reverse taper of portion, make the following process that pushes away of filtering piston 4 that a buffering effect be arranged.

The cup end 53 of cup of the present utility model 5 bottoms can with the cup 54 bottom imaginary planes that can be provided with at a distance of certain distance, when making cup 5 be positioned over desktop, a cup end 53, can not make the desktop humidity because of water recovery.

Depression bar 2 one ends of the present utility model are screw thread 22, are connected with filtration piston 4, and the other end can be a lever 1, and handled easily personnel's hand grips.Also can be divided into two bodies to lever 1 and depression bar 2, the end that depression bar 2 is attached thereto is provided with annular knurl, and there is a blind hole that cooperates with it in the central authorities of lever 1, and close-fitting is affixed with it when assembling.
