Description

Technical Field

[0001] This invention relates to the field of household appliances, specifically a multifunctional extraction system. Background Technology

[0002] Coffee machines can be categorized by whether the coffee beans are ground inside the machine, such as drip coffee machines, capsule coffee machines, and coffee grinders. In these machines, the coffee capsule contains a measured amount of coffee powder. After brewing, the used coffee capsule needs to be removed from the brewing chamber. For this purpose, some coffee machines have an opening at the top of the brewing chamber. The container holding the coffee capsule or coffee powder / packet enters or exits the brewing chamber through this opening. A brewing nozzle with a flip-top structure is installed on this opening, and the opening or closing of the brewing nozzle is controlled by a handle.

[0003] Application document CN217852458U discloses an open-capsule coffee brewing device compatible with various coffee capsules. The brewing device includes an upper brewing support and a lower brewing support that are rotatably connected. A brewing head assembly is connected to the upper brewing support, and correspondingly, multiple coffee bag assemblies that cooperate with the brewing head assembly to brew coffee are connected to the lower brewing support. The lower brewing support includes a coffee bag mounting part for mounting the multiple coffee bag assemblies.

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] Please see Figure 1-13 As shown: A multifunctional extraction system includes a water inlet component and a liquid draining component. The water inlet component is used to connect to a water source and deliver hot water, and the liquid draining component is used to drain the coffee liquid extracted from the capsule. The water inlet assembly includes an upper support frame 101, with a water inlet support frame 105 mounted on the top inner side of the upper support frame 101. An upper piercing tube 106 is fixedly installed through the axis of the water inlet support frame 105. An inner ring sealing ring 110 and an outer ring sealing ring 112 are sequentially arranged from the inside out between the outer periphery of the water inlet support frame 105 and the inner periphery of the upper support frame 101. The drain assembly includes a lower support frame 201, with an extraction frame 202 fixedly installed through the middle of the lower support frame 201. A drain hopper 203 is fixedly snapped onto the bottom outer periphery of the extraction frame 202. A snap-fit ​​sleeve 205 is fixedly embedded at the bottom end face edge of the frame 202. A lower piercing tube 206 is fixedly connected through the snap-fit ​​sleeve 205. An adjustable support assembly is provided inside the extraction frame 202 to limit and support various coffee capsules. An inner ring mounting cavity 109 is formed between the outer peripheral side wall of the water inlet support frame 105 and the upper support frame 101. An inner ring sealing ring 110 is snap-fitted into the inner ring mounting cavity 109. An outer ring mounting cavity 111 is opened on the inner side wall of the upper support frame 101. An outer ring sealing ring 112 is installed in the outer ring mounting cavity 111. like Figure 3-6 As shown in Figure 10, it also includes an adjustable support assembly for adapting to various coffee capsules. The adjustable support assembly supports, limits, and extracts coffee liquid for coffee powder bowl 401, K-CUP capsule 402, first Nestlé capsule 403, Starbucks capsule 404, and second Nestlé capsule 405, respectively. By limiting and supporting the above capsules, a set of adjustable support assemblies can infinitely adjust to adapt to various coffee capsules. A plurality of evenly distributed, arrayed diversion holes 107 are provided through the middle of the water inlet support frame 105 and around the upper barbed tube 106. A filter screen plate 108 is installed in the middle of the water inlet support frame 105 and directly above the upper barbed tube 106. A water inlet 103 is provided at the center of the top of the upper support frame 101. A water inlet sealing ring 104 is embedded in the upper inner side of the upper support frame 101 between the water inlet 103 and the filter screen plate 108. The bottom of the water inlet sealing ring 104 is flush with the filter screen plate 108. The outer periphery of the upper surface of the mesh plate 108 forms a contact seal. The bottom end face of the extraction rack 202 is provided with a first drain port 204 and the bottom center of the drain hopper 203 is provided with a second drain port 207. Several snap-fit ​​blocks 208 are fixedly connected to the top outer periphery of the extraction rack 202 in a ring array. Several support slots 102 are provided on the inner periphery of the upper support frame 101 in a ring array. The snap-fit ​​blocks 208 and the support slots 102 correspond one-to-one and snap-fit ​​each other. In this embodiment, different supports within the extraction rack 202 provide sealing and limiting support according to the different sizes of the coffee capsules being extracted. Different supports accommodate different coffee capsules, so only the compatible supports need to be replaced to support different capsules. This eliminates the need to replace the lower support rack 201 and the extraction rack 202, reducing material usage, improving the efficiency of the extraction rack 202, and avoiding repeated purchases by consumers, further reducing costs. The outer ring sealing ring 112 seals the outer periphery of the upper surface of larger coffee capsules, while the inner ring sealing ring 110 seals the outer periphery of the upper surface of smaller coffee capsules. The extraction rack 202... 2. The cooperation of various supports ensures that coffee capsules of various sizes remain stable and sealed when water is injected through the upper piercing tube 106 on their upper surface, ensuring accurate water volume. The filter plate 108 prevents coffee powder from flowing back during extraction. The upper piercing tube 106 pierces the center of the top of each coffee capsule and guides hot water into the capsule. Through the corresponding engagement of the snap-fit ​​block 208 and the support slot 102, the extraction rack 202 can be quickly snapped and fixed to the upper support rack 101, simplifying the usage steps, allowing users to quickly obtain coffee, reducing the loss of coffee flavor during the extraction process, and ensuring that the extracted coffee accurately reflects its flavor, achieving the best extraction effect.

[0022] The adjusting bracket assembly includes a support cylinder 301. A transmission rotating cylinder 302 is movably sleeved on the upper outer periphery of the support cylinder 301. Support rails 303 are installed on both the upper and lower end faces of the transmission rotating cylinder 302. The support rails 303 are embedded in the support cylinder 301 and are slidably connected to the support cylinder 301. Several mounting grooves 304 are evenly distributed in a circular array on the inner peripheral side wall of the support cylinder 301. A transmission gear 305 is provided in the middle of the inner side of each mounting groove 304. Both ends of the rotating shaft of the transmission gear 305 are fixedly connected to a transmission gear. The inner circumferential sidewall of the screw 306 and the transmission cylinder 302 is fixedly sleeved with a transmission gear ring 307. The outer sidewall of the support cylinder 301 is provided with a groove that moves in conjunction with the transmission gear ring 307. The transmission gear ring 307 and the transmission gear 305 mesh and drive each other. The transmission screw 306 is threaded with a transmission sleeve 308. The thread direction of each pair of transmission screws 306 and each pair of transmission sleeves 308 are symmetrical. Each pair of transmission sleeves 308 is hinged with a transmission inclined rod 309. Each pair of transmission inclined rods 309 is hinged together with a push block 310. The sides of the push block 310 are provided with a first clamping plate 311, a second clamping plate 312 and a third clamping plate 313 in sequence. The first clamping plate 311 and the third clamping plate 313 correspond one to one, and the second clamping plate 312 and the first clamping plate 311 are staggered. Several parallel snap-fit ​​grooves 314 are opened in the middle of the opposite sides of the first clamping plate 311 and the third clamping plate 313. Several snap-fit ​​rails 317 are fixedly connected to both sides of the second clamping plate 312. The snap-fit ​​rails 317 and the snap-fit ​​grooves 314 correspond one to one and are slidably connected. Limiting grooves 315 are opened in the middle of the upper and lower edges of the opposite sides of the first clamping plate 311 and the third clamping plate 313. Limiting sliders 316 are installed on both sides of each corner of the second clamping plate 312. The limiting sliders 316 and the limiting grooves 315 correspond one to one and are slidably connected. The bottom of the third clamping plate 313 is equipped with a support slide 318, and a support slider 319 is slidably mounted on the support slide 318. A positioning bolt 320 is threaded through the upper part of the support slider 319. A hinge seat 321 is installed in the middle of the support slider 319. A hinge block 322 is hingedly mounted on the hinge seat 321. A support rod 323 is installed on one side of the hinge block 322. A support plate 324 is installed at the end of the support rod 323. A snap-fit ​​325 and a sealing ring 327 are installed on one side of the support plate 324. The axis of the snap-fit ​​325 is coaxial with the sealing ring 327. Several fan-shaped mesh plates 326 evenly distributed in a ring array are installed on the support plate 324. A diagonal brace 328 is hinged to the lower part of the support slider 319. A connecting groove 329 is opened on the side of the support rod 323 away from the snap-fit ​​325. The connecting groove 329 corresponds one-to-one with the diagonal brace 328. In this embodiment, different limits are applied to different capsules. For capsules with a top diameter greater than a bottom diameter, the diameter of the circle enclosed by the first clamping plate 311 and the second clamping plate 312 is adjusted to enclose and fit the capsule with a top diameter greater than a bottom diameter. During enclosure, the transmission cylinder 302 is rotated, and the transmission gears 305 are driven synchronously by the transmission gear ring 307, so that each pair of transmission screws 306 synchronously pushes each pair of transmission sleeves 308 to move. The inclination angle of the transmission inclined rod 309 is adjusted, thereby adjusting the diameter of the cylinder enclosed by the first clamping plate 311. Through the sliding connection of the snap-fit ​​groove 314 and the snap-fit ​​rail 317, as well as the sliding connection of the limiting groove 315 and the limiting slider 316, the second clamping plate 312 and the first clamping plate 311 can flexibly slide to enclose cylinders of various diameters for stable enclosure and support. For capsules with a top diameter smaller than a bottom diameter, the support rod 323 is rotated to a horizontal position, and then the inclined support plate 328 is flipped so that it engages with the connecting groove 329, so that the engaging spikes 325 face upwards. Then, the transmission cylinder 302 is rotated so that the hinge block 322 forms a ring around the bottom of the capsule. Then, the positions of each support slider 319 are adjusted and fixed by the positioning bolt 320 so that the top of the capsule is flush with the upper end of the support cylinder 301. Then, each engaging spike 325 is pressed in sequence and inserted into the bottom of the capsule so that the sealing ring 327 seals against the bottom of the capsule. Then, the capsule with the adjustment bracket assembly installed is placed into the extraction rack 202 so that water can quickly enter through the upper spike tube 106 and the filtered coffee liquid can be discharged through the fan-shaped mesh plate 326, thus avoiding insufficient height of the lower spike tube 206, making the coffee extraction process smooth and natural, and adaptable to capsules of various specifications and sizes.

[0023] In summary, the corresponding engagement of the snap-fit ​​block 208 and the support slot 102 allows the extraction rack 202 to be quickly snapped and fixed to the upper support rack 101. By replacing different racks instead of different extraction components, the overall number of components is reduced, and the production quantity of the extraction rack 202 can be significantly reduced, saving material costs. The elastic and tight contact between the outer ring sealing ring 112 and the inner ring sealing ring 110 achieves efficient and stable contact sealing, ensuring efficient and accurate water intake, improving the accuracy of water volume, and ensuring the best coffee flavor. The transmission gears 305 are synchronously driven by the transmission ring 307, which in turn drives the transmission sleeves 308 to move synchronously by the transmission screws 306. The inclination angle of the transmission inclined rod 309 is adjusted, thereby adjusting the diameter of the cylinder enclosed by the first clamping plate 311. Through the sliding connection of the snap-fit ​​groove 314 and the snap-fit ​​rail 317, as well as the sliding connection of the limiting groove 315 and the limiting slider 316, the second clamping plate 312 and the first clamping plate 311 can flexibly slide to enclose cylinders of various diameters, providing stable enclosure and support, and adapting to capsules of various specifications and sizes.
