Abstract

The utility model relates to a manual pneumatic coffee pot which is characterized in that a manual pneumatic pump and a check valve are arranged inside a pot body; the air outlet of the pneumatic pump is communicated with the interior of the a net basket which is placed at the upper part of the interior of the pot body; the edge of the net basket is provided with steps overlapped on the pot body; and a pot lid is screwed at the upper part of the net basket and is in a sealed state. when the manual pneumatic coffee pot is in use, powdered coffee is put into the net basket, boiled water is poured into the net basket, the pot lid is screwed down, a piston is pressed for multiple times, air enters into the net basket to generate pressure, and liquid coffee flows out through a filter screen under the effect of pressure; The coffee prepared by such a method is pure and flavorsome in taste, sanitary and environment-friendly; and the device is convenient to control, is simple in structure, is safe and reliable and is low in manufacturing cost.

Description

A kind of manual pneumatic coffee pot

Technical field

The utility model relates to a kind of manual pneumatic coffee pot, just does through simple manual behaviour and can manufacture concentrated coffee, belongs to the daily living article field.

Background technology

The utensil of manufacturing coffee at present mainly is divided into by principle: kettle etc. is pressed in steam cooking-pot type coffee pot, water pump type pressure coffee pot, hydrocone type coffee pot, Moca coffee pot, water clock formula coffee pot, French filter; Also useful various simple strainer filtering, former structure is complicated, and manufacturing cost is high; And the coffee mouthfeel that the latter processes is light; Effect is bad, and complicated operation uses inconvenience.

Summary of the invention

In order easily to make aromatic coffee, the present invention proposes a kind of new technical scheme, and beneficial effect is: simple in structure, cost is low, and the coffee concentration of making is high, and mouthfeel is good, and is easy to use, safe and reliable.

The main technical schemes of the utility model is: in kettle body inboard manual pulsometer, breather cheek valve and unidirectional air outlet valve are housed; The gas outlet of pulsometer is in piping is switched to basket, and basket is placed on top in the kettle body, and its edge has step to ride on the kettle body; Filter screen is in the basket bottom; Pot lid has screw thread to screw on basket top, and cushion rubber is clamped between pot lid and the basket oral area, makes to be in sealing state in the basket.During use, coffee powder is placed in the basket, boiling water is poured in the basket, and the pot lid of screwing is pushed piston repeatedly, and air gets in the basket, produces pressure, just can make concentrated coffee, and the coffee taste of processing in this way is pure aromatic, hygienic environment-protecting.

Fig. 1 is the vertical section principle assumption diagram of the utility model.

Fig. 2 is the part explosive view of the utility model.

The specific embodiment

As Fig. 1, Fig. 2, shown in, the utility model mainly comprises kettle body (1), basket (2) and air pump combination.Kettle body (1) is a left and right sides structure, and a side is equipped with pulsometer, opposite side top dress basket (2), and coffee cup (20) is put in the bottom.Pulsometer has multiple version, is illustrated as the plunger type pulsometer, and the pump seat of bottom (18) sidepiece has outside check valve; Check valve is made up of conical hole, ball (17) and spring (16); Spring (16) withstands ball (17), and ball (17) withstands on the circular cone hole wall, forms unidirectional air outlet valve.The outlet nozzle (11) that unidirectional air outlet valve leads to kettle body (1) top through piping (15), outlet nozzle (11) leads in the basket (2).Go up the arrangement breather cheek valve at piston (12), breather cheek valve has multiple version, and is as shown in Figure 1; At piston (12) cylindrical the annular groove than broad is arranged, the diameter top in the annular groove is big, and the bottom is little; Cushion rubber (13) is enclosed within the annular groove, and when upwards carrying piston (12), cushion rubber (13) is by following; Cushion rubber and piston are gapped, and air gets in the pump housing (14); When pressing down piston (12), cushion rubber (13) leans on last, and cushion rubber and piston closely match, and this breather cheek valve can let people more free and relaxed when pulling piston (12) makes progress.There is screw thread at piston rod (9) two ends, and lower end and piston (12) screw and be integral, and the upper end is passed hole and button (5) on the kettle body (1) and screwed and be integral.The fine and closely woven filter screen of mesh (8) is arranged at basket (2) bottom, and basket (2) top outer circular edge has step to ride on the kettle body (1), and basket (2) oral area cylindrical has screw thread, screws with pot lid (3), and pot lid (3) the inner has cushion rubber (4) and basket (2) oral area to compress, and sealing matches.On basket (2) circumference concave step is arranged, porose on step up to basket (2) top, cover " worker " font O-ring seal (10) closely matches with outlet nozzle (11) in the hole.Basket (2) can be movable, freely takes out.Bottom (19) is contained in kettle body (1) bottom.

During use, earlier coffee powder is placed in the basket (2), then boiling water is poured in the basket (2) into the pot lid of screwing (3); Push piston (12) repeatedly, when mentioning piston (12), air gets in the pump housing (14) through the breather cheek valve on the piston (12); When depressing piston (12), the unidirectional air outlet valve of pump seat (18) sidepiece is opened automatically, and compressed air enters in the basket (2); Make water generates pressure, flow down behind water process coffee powder and the filter screen (8), just can make concentrated coffee.

In order to prevent to add the time marquis of water, water breaks up coffee powder, and coffee powder floats, and can in basket (2), add a filter (7), and filter (7) surface is covered with aperture, and a handle (6) is arranged at its top, is convenient to hand and takes.During use, can filter (7) be placed on the coffee powder top, like this, coffee powder is pressed in basket (2) bottom by filter (7), can not float, and can improve the concentration and the quality of coffee like this.Filter (7) is processed by stainless steel material, presses down by deadweight, can regulate naturally that coffee powder is suitably compressed.

Pressure in the basket (2) is that generally speaking, people's hand pressure can easily reach 8 kilograms by the strength decision of people's hand button (5); About 30～40 millimeter of the interior diameter of the pump housing (14); Theoretical Calculation can know that pressure can reach 1 standard atmospheric pressure, surpasses the service pressure of Moca coffee pot and hydrocone type coffee pot, in fact; Operating pressure in the basket (2) only needs about 0.3bar; Enough, the coffee quality can reach the effect of Moca coffee pot or steam cooking-pot type pressure coffee pot, surpasses water clock formula coffee pot.

Though this device produces pressure, and is very safe, because its pressure is little, controlled by the people, and pressure only concentrates in the basket (2), so, as long as basket (2) is solid reliably, just as safe as a house.

This installs most of part and can process with the PP plastics, also available PC or nylon plastic(s), and the pump housing can be processed with stainless steel tube, and sealing ring is processed with rubber, and is simple in structure, low cost of manufacture.

The process of manufacturing of coffee is very exquisite, and water temperature, the rate of filtration, pressure all can influence coffee taste, and the present invention can make manufacturing process grasped by producer oneself, easily makes the coffee of various tastes.

This device is left and right sides structure generally speaking, and outward appearance can be designed various shape, but the protection domain that its inner main technical schemes is a this patent.
