Description

Coffee pot

Technical field

The utility model relates to a kind of coffee pot, particularly relates to a kind of coffee pot for the preparation of Mocha coffee.

Background technology

Traditional steam pressure type coffee pot, also known as Moka coffee pot, include a upper kettle, a lower kettle, have a funnel between upper kettle and lower kettle, the suction hose of funnel stretches in lower kettle and bottom lower kettle, funnel top also has the epicoele for placing ground coffee, also have chimney formula water-supply-pipe in upper kettle, and its inside is provided with filter screen; During use, by lower kettle filled with water, ground coffee puts into the epicoele on funnel top, upper kettle, lower kettle being screwed by connection cover is placed on thermal source, when the water of kettle is by ebuillition of heated instantly, due to steam pressure again, water in lower kettle is along funnel suction hose, through the filter screen of ground coffee and upper kettle, enter kettle, flow into confession people in kettle container from water-supply-pipe and drink.

The upper kettle of this Moka coffee pot, general on market is all directly use metal (being mainly aluminium alloy and stainless steel) to manufacture, and is threaded with lower kettle with expediently kettle.Along with the development gradually of the personalization in market, diversified demand and environmental protection, upper kettle material some start to be substituted by nonmetallic materials such as pottery, heat resistant glass or environmentally-friendly plastics.These nonmetallic materials are more easily processed than metal material because of external form, profile and color various, enriched style and the kind of the clip type coffee pot that rubs greatly.But due to these nonmetallic materials not easily machining screw, can not directly with metal lower kettle threaded engagement, so in addition metal threaded connection cover must be used, the upper kettle body of nonmetallic materials and connection cover are linked into an integrated entity just passable.

Ceramic Moka coffee pot of the prior art, kettle body and water-supply-pipe integrally sinter to form, and its connection cover and lower kettle are metal material.For solving the joint and seal problem of kettle on metal connection cover and nonmetallic pottery, its traditional processing technology is that (except middle water-supply-pipe position) bottom kettle on pottery is filled the fluid sealant for bonding, and direct for connection cover glue bond is combined in bottom the upper kettle of pottery.Because upper kettle and connection cover only link together by bonding glue, be actually illusive.Hot plate in the process of coffee, the temperature of upper kettle is higher, and during Long-Time Service, the glue for bonding is easily aging and lose viscosity.On the one hand, because in the process of hotting plate coffee and cleaning coffee pot, all need kettle on multiple rotary, if it is not firm that connection cover is connected with kettle on pottery, cause inner produce gap or being separated, will cause leaking, departing from, coffee pot lost boil function and scrap; On the other hand, boil and cleaning operation process in as kettle on connection cover and pottery is because boning loosely, on pottery, kettle is likely cracked, generation human safety issues.

As preferably, the bottom of described upper kettle is provided with suitable with the centre bore making it pass with described water-supply-pipe.

As preferably, the externally threaded upper end of described water-supply-pipe has the positive stop end of the outer wall around described water-supply-pipe, is provided with the first sealing ring between the bottom surface of described positive stop end and described upper kettle.

As preferably, between the lower surface of described upper kettle and the upper surface of described connection cover, be provided with the second sealing ring.

As preferably, the top of described positive stop end has skirt border structure, described water-supply-pipe and described connection cover is screwed to provide a Handheld Division.

As preferably, the inwall of described connection cover is provided with internal thread, and the upper end of described lower kettle has the external screw thread matched with the internal thread on described inwall.

As preferably, described upper kettle is ceramic material, and described water-supply-pipe and described lower kettle are metal material.

As preferably, the position near its upper end on described lower kettle sidewall has a safety valve.

As preferably, the upper end of described suction hose has the cavity for placing coffee, and the lower end of described cavity and the lower end of described water-supply-pipe all have filter screen.

Compared with prior art, the beneficial effects of the utility model are: the coffee pot that the utility model provides, and are worn at the bottom of the kettle of upper kettle and are connected with connection cover, be firmly fixed together to make upper kettle and connection cover by water-supply-pipe.
