Abstract: A brewing structure featuring stability and water confinement is provided, including a support frame, a container, a filter, and a movable assembly. The support frame has a retention device. The container has a positioning section and a fitting section. The positioning section and the fitting section are retained on the retention device so that a brewing operation can be carried out in a stable manner at a predetermined altitude. The container forms a bore and a guide section is formed around the bore and extends downward. The movable assembly controls water discharging through the bore or blocks the bore. The movable assembly includes a body forming a water collection hole. A joint section and a water collection section are formed around a circumference of the water collection hole.

Abstract: A brewing device includes a receptacle, which has a bottom forming a bore. A filtering member is received in the receptacle. A flow control assembly is arranged below the receptacle and is vertically movable with respect to the receptacle. The flow control assembly includes a bar extendible through the bore. An upward movement of the flow control assembly pushes away a closure member sitting on the bore. A guidance section is formed below the bore. The flow control assembly includes a flow guide section corresponding to the guidance section. When the flow control assembly is moved upward, the guidance section and the flow guide section collectively form a water passage. A brewing liquid contained in the receptacle, when discharged through the bore, is shielded by the water passage and is confined and concentrated for smooth flow thereby eliminate the occurrence of leak, splash, and overflow of the brewing liquid.

Abstract: The brewing device contains a container and a functional unit beneath the container conductive to the container. The functional unit contains a pressure section and an exit section. The pressure section is conductive to and is smaller than the container. The pressure section is configured with air holes for drawing outside air. The exit section is conductive to and is smaller than the exit section. As the brewed liquid (such as the coffee brewed from the coffee powder) flows through the pressure section, it undergoes a pre-determined pressure through the air holes. Additionally, the container and the functional unit jointly achieve Venturi effect so that the brewed liquid is sped up under greater pressure difference as it passes through the exit section. As such, the molecules of the brewed liquid are activated and thinned to achieve enhanced flavor.

Abstract: Provided is a coffee making kettle using Venturi, including a kettle body having a bottom forming a through opening and defining a first chamber and a second chamber. The opening has an upper circumference from which two opposite inclined surfaces extend upward. Top edges of the inclined surfaces form a circular opening. The first chamber is located above the second chamber and is greater in volume than the second chamber. The second chamber is in communication with the through opening. When a paper filter that contains an object-to-be-brewed (such as coffee powders) is positioned in the kettle body and liquid (such as hot water) is added, the liquid is filtered by the paper filter and is guided by the inclined surfaces into the second chamber, so that the brewing liquid is subjected to the effect of Venturi to induce a pressure difference and increase of flowing speed.

Abstract: A safety and guide type brewing kettle includes a kettle body, a water stopper, a screen filter, and a retention disk. The kettle body has a cove that forms a flow guide plate for guiding liquid droplets formed on the cover into the kettle body. The kettle body has a bottom forming a through bore that receives therein a plug, which forms a through hole and an engagement section. The water stopper is arranged to block the through hole for eliminating undesired leaking. The kettle body has a lower circumference forming a projecting wall that forms legs to enclose and stably hold the kettle body. The kettle body forms at least one locking section, which engages an upper side of the screen filter. The screen filter forms a grip section that facilitates assembling/disassembling and cleaning. The screen filter forms a positioning section for positioning the water stopper.

Abstract: An infusion maker which includes a hollow body member having a surrounding flange and a through hole at the bottom and a hinged cover at the top; a filter member inside the body member covering the through hole; a blocking element for blocking the through hole; and an engaging member configured under the body member capable of moving up and down relative to the body member. The cover has a guiding plate for guiding condensed water drops to flow back into the body member. The blocking element tightly rests on a sleeve element at the through hole of the body member. The flange has a larger diameter than that of the engaging member and has a number of foot rests so as to protect the engaging member and to stably support the body member.

Abstract: A ring washer is provided at an end of the outlet of the dripping device. The ring washer has a center trough channel aligned with the outlet. A sphere is rotatably stuck at an end of the through channel of the ring washer. When the sphere is turned to a specific angle, a diametrical through channel of the sphere is substantially aligned with the through channel of the ring washer and the outlet and the fluid in the dripping device is therefore allowed to drip through. At the end of the through channel of the ring washer that interfaces with the sphere, a flexible ring element is provided that could conform to the curvature of the sphere and thereby compensate for slits that may exist between the not-so-perfectly-circular ring washer and the not-so-perfectly-round sphere.
