The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1 and Fig. 2, the filter of this pressure coffee machine includes filter 9, and filter 9 sealing rings 1, filter 2, current limliting circle 3, filter protecgulum 4, filter cup 5 and filter bonnet 7 connect and compose successively.Wrap up by sealing ring filter 2 and filter protecgulum 4 peripheries, and be arranged in the filter cup 5, the filter cup bottom is open, corresponding filter protecgulum 4 is provided with in-flanges 5.2, filter 2 is arranged on filter protecgulum 4 tops, and filter protecgulum bottom passes filter cup 5 and fixedlys connected with filter bonnet 7 by three screws 8; Filter protecgulum 4 and filter bonnet 7 are respectively arranged with protecgulum centre bore 4.1 and bonnet centre bore 7.2, and current limliting circle 3 is arranged in the protecgulum centre bore 4.1, and coffee screen pack 6 is arranged in the bonnet centre bore.Coffee screen pack 6 is provided with four layers, the bonnet centre bore 7.2 of filter bonnet 7 is provided with the step of support coffee screen pack, step side is provided with blowhole 7.1, be formed with gas-liquid mixed chamber 9.1 between step and the filter protecgulum, wherein, the filter bonnet is the dish shape, and peripheral to 7.2 inclinations of bonnet centre bore, blowhole 7.1 is higher than coffee screen pack 6 upper surfaces.Filter protecgulum 4 is the dish shape, and peripheral to 4.1 inclinations of protecgulum centre bore, upper surface is provided with and supports convex tendon 4.2; The protecgulum centre bore is a stepped hole, is provided with current limliting circle 3 in the hole, and current limliting circle center is provided with current limliting aperture 3.1.The protecgulum centre bore 4.1 peripheral corresponding bonnet centre bores 7.2 of filter protecgulum 4 bottom surfaces extend presser feet 4.3, and coffee screen pack 6 is crimped between the step surface and presser feet 4.3 of bonnet centre bore 7.2.Filter 2 is undertaken on the edge of filter protecgulum 4 and supports on the convex tendon 4.2, and the surface is uniform to be provided with some pores, and the pore aperture is less than or equal to current limliting aperture 3.1 apertures for being 0.6mm.Filter cup 5 end faces are provided with flanging 5.1, are connected with high pressure funnel 12, see Fig. 3.
