Description

Technical Field

[0001] This utility model relates to the field of coffee brewing technology, and in particular to a vibrating screen coffee brewing head. Background Technology

[0002] Coffee is a beverage made from roasted and ground coffee beans. A standard cup of coffee should not only taste bitter. Baristas meticulously perform each step when making coffee, and the final coffee served to customers will present different levels of sweetness, acidity, aroma, or cleanliness in terms of taste.

[0003] After coffee beans are ground, the particle size is inconsistent. Larger coffee powder has a weaker flavor, while smaller powder has a stronger bitterness and is not suitable for direct brewing. Usually, it is necessary to manually sift out the coffee powder that is not suitable for brewing. The sifting effect is not ideal, and it increases the time cost. In addition, the sifted coffee powder cannot be recycled in time, resulting in waste.

[0004] In response to the technical problems of poor powder sieving effect, time consumption, and inability to timely recover excess coffee powder, this application proposes a vibrating powder sieving coffee brewing head. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as poor sieving effect, time-consuming process, and inability to promptly recover excess coffee powder. The invention proposes a vibrating sieve coffee brewing head that, by setting two layers of sieve plates with different hole sizes, can remove both large and small particles, leaving suitable coffee powder for brewing. It also includes a collection box to recycle excess coffee powder for further processing or other uses.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A vibrating sieve coffee brewing head includes a coffee bowl and a coffee handle. The coffee handle is rotatably connected to an outer can, and an inner can is fixedly connected to the inner wall of the outer can. The top of the outer can has a feed inlet that penetrates both the inner wall of the outer can and the inner wall of the inner can. The top of the inner can is fixedly connected to a motor, which is connected to a sieve plate via a sieving assembly. The sieve plate has a discharge outlet. Two sets of connecting seats are fixedly connected to the outer wall of the outer can, and the connecting seats are connected to a receiving box via a snap-fit ​​assembly.

[0008] Furthermore, the sieve plate includes a coarse-hole sieve plate, a fine-hole sieve plate, and a fine powder baffle. The sieve plate is inclined, and a collar is fixedly connected to the outer diameter of the sieve plate. The collar is slidably connected to the inner wall of the outer tank.

[0009] Furthermore, a V-shaped baffle is fixedly connected to the discharge port at the top of the coarse-hole screen plate and the fine-hole screen plate.

[0010] Furthermore, the powder screening assembly includes a rotating ring fixedly connected to the output end of the motor, a connecting rod fixedly connected to the rotating ring, a shift rod rotatably connected to the other end of the connecting rod, the shift rod being slidably connected to the inner wall of the inner tank, and the inner wall of the screen plate being fixedly connected to the outer wall of the shift rod.

[0011] Furthermore, the snap-fit ​​assembly includes a snap-fit ​​block slidably connected to the inner wall of the connecting seat, a pull block fixedly connected to the side of the snap-fit ​​block facing the receiving box, a snap-fit ​​rod fixedly connected to the top of the receiving box, and a snap-fit ​​hole with the same cross-sectional area as the snap-fit ​​block on the snap-fit ​​rod.

[0012] Furthermore, a spring is fixedly connected to the inner wall of the connecting seat, and the other end of the spring is fixedly connected to the locking block.

[0013] Furthermore, a first discharge plate and a second discharge plate are fixedly connected to the outer wall of the inner tank. The first discharge plate penetrates the inner wall of the outer tank and the receiving box. A receiving pipe is provided below the second discharge plate and is fixedly connected to the outer wall of the inner tank.

[0014] Furthermore, the outer can is rotatably connected to the coffee handle via a damping rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, a motor drives a rotating ring to rotate. A connecting rod is provided on the edge of the rotating ring. When the rotating ring rotates, it drives the connecting rod to make a circular motion around the center of the rotating ring, thereby driving the moving rod to make up-and-down sliding motion on the inner wall of the inner tank, thus realizing the up-and-down vibration of the screen plate. The inclined design of the screen plate allows particles that cannot pass through the screen holes to roll down into the discharge port under the action of gravity, thereby realizing the screening and collection of particles of different sizes.

[0017] 2. In this utility model, by setting a sliding block in the connecting seat fixedly connected to the outer tank, and setting a locking rod with a locking hole on the receiving box, the sliding block can limit or disengage the locking rod, thereby allowing the receiving box to be detachably installed on the outer wall of the outer tank, making it more convenient to use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-3 This utility model provides an embodiment of a vibrating screen coffee brewing head, comprising a coffee bowl and a coffee handle. The coffee handle is rotatably connected to an outer canister 1, and an inner canister 2 is fixedly connected to the inner wall of the outer canister 1. A feed inlet is located at the top of the outer canister 1, penetrating both the inner wall of the outer canister 1 and the inner wall of the inner canister 2. A motor 3 is fixedly connected to the top of the inner canister 2, and a rotating ring 4 is fixedly connected to the output end of the motor 3. A connecting rod 5 is fixedly connected to the rotating ring 4, and a sliding rod 6 is rotatably connected to the other end of the connecting rod 5. The sliding rod 6 slides... A screen plate is fixedly connected to the inner wall of the inner tank 2 and the outer wall of the shift rod 6. The screen plate has a discharge port and includes a coarse-hole screen plate 7, a fine-hole screen plate 8 and a fine powder baffle 9. The screen plate is inclined and a collar 10 is fixedly connected to the outer diameter of the screen plate. The collar 10 is slidably connected to the inner wall of the outer tank 1. A V-shaped baffle 11 is fixedly connected to the discharge port at the top of the coarse-hole screen plate 7 and the fine-hole screen plate 8 so that the coffee powder stays on the screen plate for a longer time. The outer tank 1 is rotatably connected to the coffee handle through a damping rod 15.

[0026] Specifically, the feed inlet penetrates the inner walls of the outer tank 1 and the inner tank 2, leading to the top of the coarse-hole sieve plate 7. The connecting rod 5 is fixedly connected to the edge of the rotating surface of the rotating ring 4, so that when the rotating ring 4 rotates, it drives the connecting rod 5 to make a circular motion around the center of the rotating ring 4. When the connecting rod 5 moves, due to the rotational connection between the top of the connecting rod 5 and the moving rod 6, and under the limitation of the inner wall at the top of the inner tank 2, the moving rod 6 only makes up-down sliding motion. There are three sieve plates: the coarse-hole sieve plate 7 can screen out large particles, the fine-hole sieve plate 8 can screen out particles suitable for brewing, the fine powder baffle 9 can collect smaller coffee powder particles, and the V-shaped baffle 11 can allow coffee powder to stay on the sieve plate for a longer time, preventing smaller particles from being wrapped up and rolling off the outlet. All three sieve plates are inclined, which makes it convenient for coffee powder that has not passed through the sieve holes to roll off to the outlet under the action of gravity.

[0027] Two sets of connecting seats 17 are fixedly connected to the outer wall of the outer tank 1. A locking block 18 is slidably connected to the inner wall of the connecting seat 17. A pulling block 19 is fixedly connected to the side of the locking block 18 facing the receiving box 16. A locking rod 20 is fixedly connected to the top of the receiving box 16. The locking rod 20 has a locking hole with the same cross-sectional area as the locking block 18. A spring 21 is fixedly connected to the inner wall of the connecting seat 17. The other end of the spring 21 is fixedly connected to the locking block 18. A first discharge plate 12 and a second discharge plate 13 are fixedly connected to the outer wall of the inner tank 2. The first discharge plate 12 penetrates the inner wall of the outer tank 1 and the receiving box 16. A receiving pipe 14 is provided below the second discharge plate 13. The receiving pipe 14 is fixedly connected to the outer wall of the inner tank 2.

[0028] Specifically, the height of the locking rod 20 is consistent with the locking groove of the connecting seat 17, so that the locking rod 20 can be locked into the connecting seat 17. When the locking rod 20 is pushed into the locking groove of the connecting seat 17, the locking rod 20 squeezes the locking block 18, causing it to retract. When the locking rod 20 continues to advance until the locking hole of the locking rod 20 aligns with the cross-section of the locking block 18, the locking block 18 enters the locking hole of the locking rod 20 under the elastic force of the spring 21, thus completing the fixation of the receiving box 16. Conversely, the sliding pull block 19 is slidable to make the locking block 18 disengage from the locking hole of the locking rod 20, so that the receiving box 16 can be removed. There are two first discharge plates 12, which correspond to the two receiving boxes 16 respectively.

[0029] Working principle: When it is necessary to screen the ground coffee powder, the coffee powder is poured in through the feed inlet at the top of the outer tank 1, falling onto the coarse-mesh sieve plate 7. The motor 3 is started, and the motor 3 drives the rotating ring 4 to rotate. When the rotating ring 4 rotates, it drives the connecting rod 5 to move in a circular motion around the center of the rotating ring 4, thereby driving the moving rod 6 to slide up and down on the inner wall of the inner tank 2, which in turn drives the sieve plate to move up and down, thus creating a vibration effect on the coffee powder on the coarse-mesh sieve plate 7. Smaller particles fall through the sieve holes onto the fine-mesh sieve plate 8, while larger particles roll off the discharge port under the influence of gravity onto the first discharge plate 12 below the coarse-mesh sieve plate 7, and then fall into the collection box 16 for collecting large particles. The V-shaped baffle... 11 allows the coffee powder to remain on the sieve plate for a longer time, preventing smaller particles from being carried away and rolling off the outlet. At this time, the fine-pore sieve plate 8 continues to vibrate, further sieving the coffee powder. Smaller particles fall from the sieve holes onto the fine powder baffle 9 below. Under the action of gravity, they fall through the first discharge plate 12 below the fine powder baffle 9 into the collection box 16 for collecting small particles. Coffee powder suitable for brewing falls from the outlet of the fine-pore sieve plate 8 onto the second discharge plate 13 below, and then through the second discharge plate 13 into the receiving pipe 14. From the receiving pipe 14, it falls into the powder bowl below. Then, the outer can 1 is rotated, causing the entire sieving device to turn to one side, exposing the powder bowl below. The powder bowl is then aligned with the water outlet for brewing.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
