Abstract
Description
Technical Field
[0001] This utility model belongs to the field of capsule coffee machine technology, and in particular relates to a capsule beverage extraction device. Background Technology
[0002] A capsule-based extraction machine is an extraction device that uses high-pressure, rapid heating of water to extract the corresponding juice from the contents of a container. It is suitable for processing containers (capsules) containing ingredients, which, upon interaction with the liquid introduced into the capsule (such as hot, pressurized water), produce a beverage or edible juice. The capsule is a frustum-shaped ring, which can be filled with ingredients such as coffee powder, tea leaves, concentrated liquid beverages, or the like, and is sealed by a foil-like tear-off cap welded or pressed onto the annular edge extending radially from the sidewall of the ring. A common example of an extraction machine is the capsule coffee machine.
[0003] Chinese utility model patent document CN211582670U discloses an extraction drive device for a capsule coffee machine, including a vertical moving device and a moving drive device. The vertical moving device includes a vertical moving rod, a vertical moving guide structure, and a drive column. The vertical moving guide structure cooperates with the vertical moving rod, and the drive column is connected to the vertical moving rod. The moving drive device includes a moving drive plate and a translational guide structure. The moving drive plate is provided with a drive groove with a height difference at both ends. The drive groove includes a drive inclined groove and two drive flat grooves located at both ends of the drive inclined groove. The translational guide structure cooperates with the moving drive plate. The drive column is inserted into the drive groove and cooperates with the drive groove.
[0004] The movable drive plate is connected to the drive motor of the capsule coffee machine; the extraction device is connected to the vertical moving rod. The drive motor drives the movable drive plate to move horizontally, and the drive slot drives the drive column to move vertically, thereby causing the extraction device to move vertically. Therefore, this application can drive the extraction device to move vertically.
[0005] In the aforementioned patent document's technical solution, the extraction device moves downward along the vertical moving rod to the top side of the coffee capsule and punctures the coffee capsule's membrane to complete the extraction. Since the coffee capsule is supported by the capsule pushing device, when the extraction device presses down, the top side of the coffee capsule will be subjected to force. Furthermore, when adding extraction water into the coffee capsule, the coffee capsule box will bend and deform downward, resulting in a gap between the coffee capsule and the bottom of the extraction device, causing water and coffee to overflow from the puncture hole.

[0029] In one embodiment of the capsule-type beverage extraction device of this utility model, please refer to... Figures 1 to 6Specifically, the capsule-type beverage extraction device 10 of this embodiment is located inside a capsule coffee machine, which also includes a receiving seat 20 for receiving capsule coffee. The capsule-type beverage extraction device 10 includes a seat 100, a pressing mechanism 200, and a water supply device 300. The seat 100 has a guide hole 101, and the bottom of the seat 100 is provided with a support slide 102 for supporting the receiving seat 20. The edge of the guide hole 101 extends upward through a guide sleeve 110. The pressing mechanism 200 includes a pressure plate 210, a pressing drive 220, and a needle 230. The pressure plate 210 is slidably connected inside the guide sleeve 110. The pressing drive 220 is located at the upper end of the guide sleeve 110 and connected to the pressure plate 210 for pushing the pressure plate 210 to move up and down. The needle 230 is located at the bottom end of the pressure plate 210 and connected to the water supply device 30 pipe. The needle 230 is used to puncture the sealing film of the capsule coffee.
[0030] Specifically, the coffee capsule can be placed in the receiving seat 20 and pushed into the support slide 102, so that the receiving seat 20 is supported in the support slide 102, and the top side of the coffee capsule is in contact with the bottom of the seat 100. The pressing drive 220 drives the pressure plate to move downward along the guide sleeve 110 and fit against the top side of the coffee capsule. At the same time, the needle 230 punctures the membrane of the coffee capsule, and water is injected into the capsule through the water supply device 30 to achieve coffee extraction. Since the coffee capsule is located between the receiving seat 20 and the bottom of the seat 100, it can effectively limit the capsule box, and after the extraction water is injected, it will not cause the capsule box to deform, thus avoiding the problem of water and coffee spillage.
[0031] Furthermore, refer to Figure 5 and Figure 6 A connecting seat 240 extends upward from the top side of the pressure plate 210. The connecting seat 240 has a downward-extending mounting hole 241. The bottom of the mounting hole 241 has a through hole that passes through the pressure plate 210. The needle tube 230 passes through the through hole 241. The upper end of the needle tube 230 has a limiting part 231, which limits it within the mounting hole 241. A pipe connector 250 is also connected to the upper end of the mounting hole 241, and the pipe connector 250 is connected to the water supply device 30 pipe. This achieves the connection between the needle tube 230 and the pressure plate 210, and the connection between the water supply device 30 pipe.
[0032] Furthermore, refer to Figure 5 and Figure 6The pipe connector 250 includes a body 251, which covers the top side of the connector 240. A water outlet pipe 252, extending into the mounting hole 241, is located on the bottom side of the body 251 and is pressed against the top side of the limiting part 231. An interface 253 is located on one side of the body 251, communicating with the water outlet pipe 252 and also connecting to the water supply device 30 pipe. Screw holes are provided on the body 251, through which locking screws pass and connect to the connector 240.
[0033] Furthermore, refer to Figure 3 and Figure 4 The lower end of the pressure plate 210 is also covered by a silicone sleeve 260. The outer ring of the pressure plate 210 is provided with a limiting ring groove, and the side arm of the silicone sleeve 260 is provided with a protruding ring that mates with the limiting ring groove. The bottom of the silicone sleeve 260 is provided with a vent hole for the venting needle tube 230. In this embodiment, the silicone sleeve 260 can increase the sealing between the silicone sleeve and the top surface of the coffee capsule, further preventing water and coffee from spilling out.
[0034] Furthermore, refer to Figure 3 The bottom of the silicone sleeve 260 extends downward around the edge of the vent hole, forming a sealing horn 261 that acts as a suction cup. A needle 230 extends downward from the sealing horn 261. In this embodiment, after the needle 230 punctures the membrane, the sealing horn 261 adheres to and adheres to the surface of the membrane. Therefore, water leakage can be further prevented when water is injected into the capsule.
[0035] Furthermore, refer to Figures 2 to 5 The downward pressure drive component 220 includes a rotating shaft 221, a motor 222, and a connecting member 223. The rotating shaft 221 is rotatably connected to the upper end of the guide sleeve 110, and the motor 222 is connected to the rotating shaft 221 to drive the rotating shaft 221 to rotate. The rotating shaft 221 is provided with an eccentric member 224, and the upper end of the connecting member 223 extends with a first connecting portion 225, which is rotatably connected to the eccentric member 224. The bottom end of the connecting member 223 is provided with a second connecting portion 226, which is rotatably connected to the pressure plate 210. In this embodiment, the rotating shaft 221 is driven to rotate by the motor 222, causing the eccentric member 224 to push the connecting member 223, which in turn causes the connecting member 223 to swing and push the pressure plate 210 to rise and fall.
[0036] Furthermore, refer to Figure 2 and Figure 4The guide sleeve 110 is provided with guide grooves 111 on both sides, and guide grooves 111 are provided with slide rods 112. The pressure plate 210 is provided with ears 211 on both sides, which are fitted onto the slide rods 112. Support springs 212 are fitted onto the slide rods 112, supporting the pressure plate 210. In this embodiment, when the pressure plate 210 moves upward, the support springs 212 push the pressure plate 210 back to its original position. Furthermore, the support springs 212 prevent any wobbling gaps in the pressure plate 212. Specifically, the support springs 212 ensure that the pressure plate 212 is always tightly connected to the connector 223, thereby accurately controlling the downward pressure distance of the pressure plate 210. This avoids the problem that the pressure plate 210 might contact the coffee capsule without receiving a downward driving force, which could lead to the pressure plate 210 breaking the sealing film at the mouth of the coffee capsule after receiving a driving force.
[0037] Furthermore, the top side of the pressure plate 210 is provided with a downwardly recessed cavity, and the side wall of the cavity is provided with a transition position, and the second connecting part 226 is rotatably connected to the transition position.
[0038] Furthermore, refer to Figure 2 and Figure 5 The rotating shaft 221 is also equipped with a Hall switch 227, and the guide sleeve 110 is also equipped with sensors located on both sides of the Hall switch 227. This allows control of the rotation angle of the rotating shaft 221, thereby controlling the lifting height of the pressure plate 210.
[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
