Description

Upper end head of coffee maker

Technical Field

The utility model relates to a technical field is made to the coffee machine, specifically says to an upper end of coffee machine brewing device.

Background

The upper end head detachably arranged at the top of a brewing cavity of a coffee machine, namely a coffee machine brewing device, is one of important parts of the coffee machine, and has the functions of plugging and sealing the opening of the brewing cavity, filtering and outputting coffee. Generally comprises an upper end body, a coffee output pipe which is provided with a coffee outlet and is communicated with a brewing cavity, and a filtering device which is positioned below an inlet of the coffee output pipe and is also called a filter screen or a filter plate. The coffee passes through the filter device from the brewing chamber upwards, passes through the coffee outlet pipe from the inlet and then is output from the outlet at the top.

The filter plate at the upper end of the coffee machine brewer in the prior art passes through the central through hole by a screw and is screwed in the threaded hole at the lower end of the upper end body. The structure has the following defects in practical application: 1. the central position occupied by the big end of the screw and the filter plate on the periphery of the screw are not provided with filter holes for strength, thereby greatly reducing the filter area of the filter plate and influencing the filter speed, namely the output speed and the output quantity of coffee. 2. The filter plate bears corresponding pressure in the brewing process, the filter plate is generally made thicker to ensure the strength, and the thickness of the plate is deep relative to the depth of the hole, so that the aperture of the filter hole is objectively limited to be not too small, otherwise, the filter plate is easy to block. However, the large pore size of the filter pores makes the particles contained in the delivered coffee too large, which directly affects the filtering quality and the taste of the coffee.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide an upper end of coffee machine brewing device that can increase substantially filter area and can guarantee filter intensity and filtration pore aperture as little as possible.

The technical solution of the utility model is that, an upper end of coffee machine brewing device is provided, including upper end body, coffee output tube and the filter equipment who is located the import below of coffee output tube, filter equipment is two boards of upper plate and hypoplastron, and the filter of hypoplastron for being equipped with a plurality of filtration pore, upper plate are the backup pad of accessible liquid, the outer circumference reciprocal anchorage of backup pad and filter.

After the structure above the adoption, the utility model relates to a coffee machine brewage ware's top end has following advantage: the coffee machine brewing device completely overcomes the defects of the upper end of the coffee machine brewing device in the prior art, the central position of the filter plate is not shielded, and the filter holes can be arranged, so that the filter area of the filter plate is greatly increased, the filter speed is greatly increased, and the coffee output speed and the coffee output quantity are greatly increased. Because the backup pad has guaranteed intensity, the filter can be as thin as possible, and the hole on the sheet metal also can be as little as possible, because the sheet is thin with regard to the hole shallow, the filter hole blocking phenomenon can not appear, and the sheet is thin, from the technology, can corrode the pore-forming to the sheet metal, the punching press pore-forming of the thick plate of prior art, its simple process is swift. The pore diameter of the filtering holes is as small as possible, so that the particles contained in the output coffee are small, thereby ensuring the filtering quality and enhancing the taste of the coffee.

Furthermore, an upward first convex ring is arranged on the outer circumference of the filter plate, an upward second convex ring is arranged on the outer circumference of the support plate, the first convex ring of the filter plate is sleeved outside the second convex ring of the support plate, and the first convex ring and the second convex ring are fixed with each other. After the structure more than adopting, the intensity of filter is high relatively, and the backup pad is bigger to the holding area of filter, and mechanical properties is better.

Further, the first protruding circle of filter welds each other with the second protruding circle of backup pad, and the rand has been moulded plastics outward to the protruding circle after the welding, and there is the draw-in groove at the top of rand, and there is the bulge loop bottom of top end body, and the bulge loop is connected with the draw-in groove. After the structure more than adopting, the combination of filter and backup pad is firm, and the rand of moulding plastics outward of protruding circle after the welding not only does benefit to the sealed of filter equipment and top end body, makes things convenient for being connected of filter equipment and top end body again.

Furthermore, a first clamping ring is molded outside the welded convex ring, a first clamping groove is formed in the top of the first clamping ring, a first convex ring is arranged at the bottom end of the upper end body, the cross section of the first clamping groove is rectangular, the cross section of the first convex ring is triangular, and the first convex ring is clamped in the first clamping groove and welded by ultrasonic waves. After adopting above structure, provide the embodiment of the cross section of rand, draw-in groove and bulge loop, first draw-in groove and first bulge loop joint location adopt again after the ultrasonic bonding this filter equipment and the top end body between fixed and sealed firm reliable.

Furthermore, a second clamping ring is injected outside the welded convex ring, a second clamping groove is formed in the top of the second clamping ring, a second convex ring is arranged at the bottom end of the upper end head body and clamped in the second clamping groove, the cross section of the second clamping groove is circular, and the size of the opening of the second clamping groove is smaller than the diameter of the second clamping groove; the cross section of the second convex ring is also circular, and the width size of the root of the second convex ring is smaller than the diameter size of the second convex ring. After adopting above structure, provide the cross section's of rand, draw-in groove and bulge loop another kind of embodiment, the rand of moulding plastics elasticity nature is played, connects reliably and removable each other to satisfy the needs of washing and maintenance under the special circumstances.

Furthermore, the thickness of the filter plate is smaller than that of the support plate, the support plate is provided with a plurality of through holes, and the diameter of the filter holes of the filter plate is smaller than that of the through holes of the support plate. After the structure more than adopting, the filter can be as thin as possible, and the hole on the filter can be as little as possible, nevertheless has the backup pad that is equipped with a plurality of relatively big through-holes to support, and the backup pad is bigger to the support area of filter, and the atress is more even, and the intensity of filter is more guaranteed.
