Technical Field

[0001] This utility model relates to a plant extraction machine, and more particularly to a plant extraction machine that can stably control the flow rate of liquid flowing into plant raw material powder. Background Technology

[0002] Iced drip coffee is made by placing ice cubes above a coffee machine, allowing the melting ice water to drip into coffee grounds. However, this method makes it difficult to control the rate at which the melting ice water drips into the coffee grounds, and it also doesn't allow users to adjust the drip rate themselves. Therefore, controlling the drip rate to brew coffee has become an issue that needs to be addressed. Utility Model Content

[0023] Before this utility model is described in detail, it should be noted that similar components are represented by the same numbers in the following description.

[0024] See Figures 1 to 3 In one embodiment of the plant extractor 100 of this utility model, a liquid 91 (e.g., water) is slowly dripped into a plant raw material powder 92 (e.g., coffee powder) to extract a plant juice 93 (e.g., coffee). The plant extractor 100 is a portable coffee machine, but is not limited thereto. The plant extractor 100 includes a lower container 1, a filter cup 2, an upper container 3, and a conveying device 4.

[0025] See Figure 3 The lower container 1 includes a container body 11 and a handle 12 disposed on the container body 11. The container body 11 is used to hold the plant juice 93 extracted after the liquid 91 flows through the plant raw material powder 92. The container body 11 of the lower container 1 is made of heat-insulating material. The handle 12 has a connecting ring 121 and a grip 122. The connecting ring 121 is screwed to the container body 11, for example, by a screw connection. The grip 122 protrudes from the connecting ring 121 for the user to hold.

[0026] The filter cup 2 is detachably mounted on and supported by the connecting ring 121 of the lower container 1. The filter cup 2 is housed within the container body 11 of the lower container 1 to store the plant raw material powder 92. A drain hole 21 is formed at the bottom of the filter cup 2. The drain hole 21 is used to allow the liquid 91 flowing through the plant raw material powder 92 to drain into the container body 11 to form the plant juice 93.

[0027] The upper container 3 is located above the filter cup 2 and is used to store the liquid 91. The upper container 3 is made of heat-insulating material. In this embodiment, an ice cube 90 is placed inside the upper container 3. The ice cube 90 melts to form the liquid 91. In another embodiment of this invention, the upper container 3 directly stores the liquid 91.

[0028] See Figures 3 to 5The delivery device 4 is disposed between the filter cup 2 and the upper container 3. The delivery device 4 includes a tubing assembly 41, a peristaltic pump 42, and a knob 43. The tubing assembly 41 has an inlet 411 for allowing the liquid 91 in the upper container 3 to flow in, and an outlet 412 opposite to the inlet 411 and corresponding to the filter cup 2 for discharging the liquid 91. The tubing assembly 41 has a flexible tube 413 between the inlet 411 and the outlet 412. The inner diameter of the flexible tube 413 is between 1 mm and 10 mm. In this embodiment, the inner diameter of the flexible tube 413 is preferably between 1 mm and 5 mm, and more preferably between 1 mm and 3 mm. The smaller the inner diameter of the flexible tube 413, the easier it is to control the flow rate and volume of the liquid 91 within the flexible tube 413, and this also contributes to its stability.

[0029] The peristaltic pump 42 is operable to squeeze the flexible tube 413 of the infusion tubing assembly 41, so that the infusion tubing assembly 41 delivers the liquid 91 stored in the upper container 3 to the filter cup 2. The peristaltic pump 42 has a housing 421 through which the flexible tube 413 passes, a motor 422 disposed in the housing 421, and a rotating assembly 423 connected to and driven by the motor 422. The rotating assembly 423 has a turntable 424 connected to the motor 422, and a plurality of squeezing rollers 425 rotatably pivotally connected to the turntable 424 and arranged in a ring shape at intervals from each other. The squeezing rollers 425 cooperate with the housing 421 to squeeze the flexible tube 413. In this embodiment, six squeezing rollers 425 are illustrated, but this number is not limited. The motor 422 is operable to control the rotation speed of the rotating assembly 423. To enable more precise control of the flow rate of the liquid 91 delivered by the flexible tube 413, the motor 422 is a low-speed motor. The motor 422 can be operated to a speed between 5 and 60 revolutions per minute. In one embodiment of this invention, the motor 422 can be operated to a speed between 5 and 40 revolutions per minute. In another embodiment of this invention, the motor 422 can be operated to a speed between 10 and 40 revolutions per minute.

[0030] The knob 43 is electrically connected to the motor 422 via a circuit device (not shown) and is used by the user to rotate it to adjust the speed of the motor 422.

[0031] In implementing this invention, firstly, the ice cube 90 is placed in the upper container 3. The plant raw material powder 92 is stored in the filter cup 2. Next, the user rotates the knob 43 to adjust the motor 422 to the desired speed, causing the motor 422 to drive the rotating component 423 to rotate. When the rotating component 423 rotates, the extrusion wheel 425 rolls along the flexible tube 413 and, together with the housing 421, extrudes the flexible tube 413. The extrusion wheel 425 extrudes and releases the flexible tube 413 to generate a vacuum suction, allowing the flexible tube 413 to draw in the liquid 91 from the inlet 411 and discharge the liquid 91 towards the outlet 412. Due to the low rotation speed of the rotating component 423 driven by the motor 422 and the small inner diameter of the flexible tube 413, the liquid 91 can slowly drip into the plant raw material powder 92 in the form of water droplets. After the liquid 91 flows through the plant raw material powder 92, it will be discharged through the drain hole 21 to form the plant juice 93 flowing into the container body 11. When the plant juice 93 is finished, the conveying device 4 is removed from the top of the filter cup 2 and the filter cup 2 is removed from the connecting ring 121 of the handle 12, so that the user can hold the handle 122 to pour the plant juice 93 out of the container body 11.

[0032] In summary, the plant extractor 100 of this embodiment, through the peristaltic pump 42 design of the conveying device 4, can stably control the flow rate of the liquid 91 discharged from the outlet 412 of the infusion tube assembly 41 to the filter cup 2. Furthermore, the knob 43 allows the user to rotate and adjust the speed of the motor 422, enabling the conveying device 4 to meet the user's need to adjust and control the flow rate of the liquid 91 discharged to the filter cup 2. Therefore, the purpose of this utility model is indeed achieved.
