Description

Technical Field

[0001] This utility model belongs to the field of beverage preparation, specifically relating to a capsule beverage brewing device and a beverage brewing machine. Background Technology

[0002] Capsules used to prepare beverages such as coffee, tea, chocolate, or milk coffee are becoming increasingly popular with consumers. These capsules typically contain one or more extracts such as coffee powder, milk powder, or cocoa powder. Beverage brewing machines brew the contents of the capsules to obtain the beverage.

[0003] The brewing chamber of a beverage brewing machine typically includes a capsule chamber, a mounting base, and a cover plate equipped with piercing needles. The capsule chamber is used to hold capsules, and the mounting base is used to insert the capsule chamber. When the capsule is installed in place, the piercing needles on the mounting base pierce the capsule. When water is introduced into the capsule through the mounting base, the water flow enters the gap between the capsule chamber and the mounting base, pushing the capsule chamber and capsule towards the cover plate so that the capsule is close to the cover plate and pierced, allowing the beverage to flow out through the passage on the cover plate.

[0004] However, currently, the sealing ring between the capsule chamber and the mounting base of beverage brewing machines on the market is a solid annular sealing ring. In order to ensure the sealing effect, the sealing ring is interference-fitted with the mounting base and the capsule chamber. Therefore, the friction between the sealing ring, the capsule chamber and the mounting base is relatively large. When water enters the mounting base, the water flow is difficult to push the capsule chamber and capsule towards the cover plate, which in turn prevents the capsule from being punctured by the cover plate, affecting the operation of the beverage brewing machine. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a capsule beverage brewing device to solve the problem that the capsule chamber is difficult to move the capsule under the propulsion of water flow.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a capsule beverage brewing device, comprising: a mounting base, which has a mounting groove for mounting a capsule chamber, a liquid inlet channel communicating with the mounting groove, and a rear needle for piercing the tail of the capsule; a capsule chamber, which is embedded in the mounting groove and slidably connected to the mounting base for accommodating capsules; and a cover plate, which restricts the travel of the capsule by covering the opening of the capsule chamber, and has a front needle for piercing the head of the capsule and a liquid outlet channel for beverage flow; the outer side wall of the capsule chamber and the inner side wall of the mounting groove are sealed together by an outer sealing ring to form a liquid inlet cavity communicating with the liquid inlet channel between the capsule chamber and the mounting base, the outer sealing ring including a first outer sealing lip abutting against the mounting base and a second outer sealing lip abutting against the capsule chamber, the first outer sealing lip and the second outer sealing lip being connected on the side away from the liquid inlet cavity to form a first water-holding gap with an opening facing the liquid inlet cavity on the outer sealing ring. This technical solution has the following technical effects:

[0007] This invention features an external sealing ring between the capsule chamber and the mounting base, creating an inlet chamber that communicates with the inlet channel. In use, a capsule is placed on the capsule chamber, and a needle is inserted into the capsule chamber to puncture the tail of the capsule, creating an opening that connects the capsule to the inlet chamber. The cover is then closed to the opening of the capsule chamber, limiting the capsule's travel. When the beverage brewer is started, water flows into the inlet chamber through the inlet channel. Some of the water in the inlet chamber enters the capsule to brew the beverage. The water flow in the inlet chamber is blocked by the external sealing ring, causing the water pressure to gradually increase and push the capsule chamber towards the cover until the capsule head abuts against the cover. At this point, the needle on the cover punctures the capsule head, allowing the beverage inside the capsule to flow out through the outlet channel on the cover. Because a first water-storing gap is formed between the first and second outer sealing lips on the outer sealing ring, opening towards the liquid inlet chamber, when water flow in the liquid inlet chamber impacts the outer sealing ring, water flows into the first water-storing gap. The water flow in the first water-storing gap pushes the first outer sealing lip towards the mounting base, causing it to fit tightly against the mounting base. Simultaneously, it pushes the second outer sealing lip towards the capsule chamber, causing it to fit tightly against the capsule chamber, thus improving the sealing performance between the outer sealing ring, the mounting base, and the capsule chamber. This results in a good sealing effect. Furthermore, during the sliding of the capsule chamber… At the same time, the first and second outer sealing lips can maintain a close fit with the mounting base and capsule chamber. Compared with the interference fit between the outer sealing ring and the capsule chamber and mounting base, the friction between the outer sealing ring and the capsule chamber and mounting base can be greatly reduced. When the water flow pushes the capsule chamber and capsule towards the cover plate, no large water pressure is required, which makes the capsule chamber slide more smoothly and avoids the capsule and capsule chamber getting stuck on the mounting base due to the outer sealing lip. This ensures that the capsule chamber can move smoothly to the front needle on the cover plate under the push of the water flow to puncture the capsule, thereby ensuring the stable operation of the beverage brewing machine.

[0008] In the aforementioned capsule beverage brewing device, the first and second outer sealing lips are integrally formed, so that the axial cross-section of the outer sealing ring is V-shaped. This allows the first and second outer sealing lips, under their own elastic force, to extend in opposite directions from the ends near the liquid inlet chamber. When no water enters the first water storage gap, the first and second outer sealing lips can maintain contact with the mounting base and the capsule chamber, respectively. When water enters the first water storage gap, the water flow directly impacts the first and second outer sealing lips, causing them to adhere to the mounting base and the capsule chamber, respectively. In other words, whether impacted by water flow or not, the outer sealing ring can maintain a seal between the outer wall of the capsule chamber and the inner wall of the mounting base, resulting in a good sealing effect.

[0009] In the aforementioned capsule beverage brewing apparatus, an outer sealing groove is provided on the outer wall of the capsule chamber. A second outer sealing lip is embedded in the outer sealing groove, and a first outer sealing lip extends out of the outer sealing groove to abut against the inner wall of the mounting groove. This serves to axially limit the outer sealing ring. When the capsule chamber slides, the outer sealing ring moves axially with the capsule chamber, preventing the outer sealing ring from disengaging from the capsule chamber during sliding and ensuring a stable seal between the outer sealing ring and the mounting base.

[0010] In the aforementioned capsule beverage brewing apparatus, the thickness of the second outer sealing lip is greater than the thickness of the first outer sealing lip. This ensures that the second outer sealing lip is more securely embedded in the outer sealing groove, preventing excessive deformation during sliding with the capsule chamber and guaranteeing a seal between the second outer sealing lip and the capsule chamber.

[0011] In the aforementioned capsule beverage brewing apparatus, an inner sealing ring is provided on the inner wall of the capsule compartment. The inner sealing ring includes a first inner sealing lip and a second inner sealing lip. When the capsule is placed in the capsule compartment, the first inner sealing lip abuts against the capsule compartment, and the second inner sealing lip abuts against the outer wall of the capsule. The sides of the first and second inner sealing lips away from the liquid inlet cavity are connected to form a second water-retaining gap with an opening facing the liquid inlet cavity on the inner sealing ring. When the capsule is placed in the capsule compartment, the side of the first inner sealing lip near the liquid inlet cavity abuts against the inner wall of the capsule compartment, and the side of the second inner sealing lip near the liquid inlet cavity abuts against the outer wall of the capsule, thus forming a second water-retaining gap with an opening facing the liquid inlet cavity on the inner sealing ring. When water flows from the inlet chamber into the capsule, some water enters the gap between the capsule and the capsule chamber. The inner sealing ring seals this gap, preventing water from overflowing. Because a second water-retaining gap is formed between the first and second inner sealing lips of the inner sealing ring, opening towards the inlet chamber, water enters this gap when it impacts the inner sealing ring. The water in this gap pushes the first inner sealing lip towards the capsule chamber, ensuring a tight seal. Simultaneously, it pushes the second inner sealing lip towards the capsule, ensuring a tight seal between the second inner sealing lip and the capsule. This improves the sealing performance between the inner sealing ring, the capsule, and the capsule chamber, resulting in a good seal. After the capsule is prepared, the inner sealing ring, no longer impacted by water, returns to its original position due to its elasticity, reducing the contact area between the second inner sealing lip and the capsule. This allows the user to easily remove the capsule from the capsule chamber, enhancing the user experience.

[0012] In the aforementioned capsule beverage brewing apparatus, the first inner sealing lip and the second inner sealing lip are integrally formed, so that the axial cross-section of the inner sealing ring is V-shaped. This allows the first and second inner sealing lips, under their own elastic force, to extend in opposite directions from the ends closest to the liquid inlet chamber. When the capsule is inserted, the capsule compresses the second inner sealing lip, thereby improving the sealing effect between the second inner sealing lip and the capsule.

[0013] In the aforementioned capsule beverage brewing apparatus, an inner sealing groove is provided on the inner wall of the capsule chamber. A first inner sealing lip is embedded in the inner sealing groove, and a second inner sealing lip extends out of the inner sealing groove to abut against the capsule. This axially limits the inner sealing ring, ensuring a stable seal between the inner sealing ring and the capsule chamber.

[0014] In the aforementioned capsule beverage brewing apparatus, the thickness of the first inner sealing lip is greater than the thickness of the second inner sealing lip. This ensures that the first inner sealing lip is more securely embedded in the inner sealing groove, preventing excessive deformation of the first inner sealing lip during capsule installation and guaranteeing a seal between the first inner sealing lip and the capsule chamber.

[0015] In the aforementioned capsule beverage brewing apparatus, the inner sealing groove is located closer to the tail of the capsule within the capsule chamber. That is, when the capsule is placed in the capsule chamber, the inner sealing groove faces the side wall of the capsule, and the distance between the inner sealing groove and the capsule head is greater than the distance between the inner sealing groove and the capsule tail. This ensures that the inner sealing ring is sealed and connected near the capsule tail, effectively blocking water flow into the gap between the capsule and the capsule chamber, preventing excessive water from entering between the capsule and the capsule chamber.

[0016] This utility model also provides a beverage brewing machine, which includes the above-mentioned capsule beverage brewing device.

[0031] This utility model discloses a capsule beverage brewing device, comprising: a mounting base having a mounting groove for mounting a capsule chamber, a liquid inlet channel communicating with the mounting groove, and a rear needle for piercing the tail of the capsule; a capsule chamber being embedded in the mounting groove and slidably connected to the mounting base for accommodating a capsule; and a cover plate that restricts the travel of the capsule by covering the opening of the capsule chamber, having a front needle for piercing the head of the capsule, and a liquid outlet channel for beverage outflow; the outer side wall of the capsule chamber and the inner side wall of the mounting groove are sealed together by an outer sealing ring to form a liquid inlet cavity communicating with the liquid inlet channel between the capsule chamber and the mounting base, the outer sealing ring including a first outer sealing lip abutting against the mounting base and a second outer sealing lip abutting against the capsule chamber, the first outer sealing lip and the second outer sealing lip being connected on the side away from the liquid inlet cavity to form a first water storage gap on the outer sealing ring with an opening facing the liquid inlet cavity. This invention features an external sealing ring between the capsule chamber and the mounting base, creating an inlet chamber that communicates with the inlet channel. In use, a capsule is placed on the capsule chamber, and a needle is inserted into the capsule chamber to puncture the tail of the capsule, creating an opening that connects the capsule to the inlet chamber. The cover is then closed to the opening of the capsule chamber, limiting the capsule's travel. When the beverage brewer is started, water flows into the inlet chamber through the inlet channel. Some of the water in the inlet chamber enters the capsule to brew the beverage. The water flow in the inlet chamber is blocked by the external sealing ring, causing the water pressure to gradually increase and push the capsule chamber towards the cover until the capsule head abuts against the cover. At this point, the needle on the cover punctures the capsule head, allowing the beverage inside the capsule to flow out through the outlet channel on the cover. Because a first water-storing gap is formed between the first and second outer sealing lips on the outer sealing ring, opening towards the liquid inlet chamber, when water flow in the liquid inlet chamber impacts the outer sealing ring, water flows into the first water-storing gap. The water flow in the first water-storing gap pushes the first outer sealing lip towards the mounting base, causing it to fit tightly against the mounting base. Simultaneously, it pushes the second outer sealing lip towards the capsule chamber, causing it to fit tightly against the capsule chamber, thus improving the sealing performance between the outer sealing ring, the mounting base, and the capsule chamber. This results in a good sealing effect. Furthermore, during the sliding of the capsule chamber… At the same time, the first and second outer sealing lips can maintain a close fit with the mounting base and capsule chamber. Compared with the interference fit between the outer sealing ring and the capsule chamber and mounting base, the friction between the outer sealing ring and the capsule chamber and mounting base can be greatly reduced. When the water flow pushes the capsule chamber and capsule towards the cover plate, no large water pressure is required, which makes the capsule chamber slide more smoothly and avoids the capsule and capsule chamber getting stuck on the mounting base due to the outer sealing lip. This ensures that the capsule chamber can move smoothly to the front needle on the cover plate under the push of the water flow to puncture the capsule, thereby ensuring the stable operation of the beverage brewing machine.

[0037] Example 1:

[0038] A capsule beverage brewing device, such as Figures 1 to 5 As shown, the device includes a mounting base 100, a capsule chamber 200, and a cover plate 300. The mounting base 100 is provided with a mounting groove 110 for mounting the capsule chamber 200, a liquid inlet channel 120 communicating with the mounting groove 110, and a rear needle 130. The capsule chamber 200 is embedded in the mounting groove 110 to accommodate capsules 600. The capsule chamber 200 is slidably connected to the mounting base 100, so that the capsule chamber 200 can slide on the mounting base 100. The cover plate 300 is provided at the opening of the mounting groove 110, which can cover or open the opening of the capsule chamber 200. The cover plate 300 is provided with a front needle and a liquid outlet channel 310 for beverage to flow out. An outer sealing ring 400 is clamped between the outer wall of the capsule chamber 200 and the inner wall of the mounting groove 110. The capsule chamber 200 and the mounting base 100 are sealed by the outer sealing ring 400 to form an inlet cavity 140 that communicates with the inlet flow channel 120 between the capsule chamber 200 and the mounting base 100. The outer sealing ring 400 includes a first outer sealing lip 410 and a second outer sealing lip 420. The sides of the first outer sealing lip 410 and the second outer sealing lip 420 away from the inlet cavity 140 are connected. The side of the first outer sealing lip 410 close to the inlet cavity 140 abuts against the mounting base 100, and the side of the second outer sealing lip 420 close to the inlet cavity 140 abuts against the capsule chamber 200, so that a first water storage gap 430 with an opening facing the inlet cavity 140 is formed on the outer sealing ring 400.

[0039] This invention establishes an outer sealing ring 400 between the capsule chamber 200 and the mounting base 100, creating an inlet chamber 140 that communicates with the inlet channel 120. In use, the capsule 600 is placed on the capsule chamber 200, and then a needle 130 is inserted into the capsule chamber 200 to pierce the tail of the capsule 600, creating an opening at the tail to allow communication between the capsule 600 and the inlet chamber 140. Then, the cover plate 300 is closed to the opening of the capsule chamber 200 to limit the travel of the capsule 600. When the beverage brewing machine is started, the water flow... Water enters the inlet chamber 140 through the inlet channel 120, and part of the water in the inlet chamber 140 enters the capsule 600 to brew the inside of the capsule 600 to form a beverage. The water flow in the inlet chamber 140 is blocked by the outer sealing ring 400, which causes the water pressure in the inlet chamber 140 to gradually increase and push the capsule chamber 200 towards the cover plate 300 until the head of the capsule 600 abuts against the cover plate 300. At this time, the front needle on the cover plate 300 pierces the head of the capsule 600, so that the beverage inside the capsule 600 flows out through the outlet channel 310 on the cover plate 300. Because a first water-storing gap 430 with an opening facing the liquid inlet chamber 140 is formed between the first outer sealing lip 410 and the second outer sealing lip 420 on the outer sealing ring 400, when the water flow in the liquid inlet chamber 140 impacts the outer sealing ring 400, the water flow enters the first water-storing gap 430. The water flow in the first water-storing gap 430 pushes the first outer sealing lip 410 towards the mounting base 100, making the first outer sealing lip 410 fit tightly against the mounting base 100. At the same time, it pushes the second outer sealing lip 420 towards the capsule chamber 200, making the second outer sealing lip 420 fit tightly against the capsule chamber 200, improving the sealing performance between the outer sealing ring 400 and the mounting base 100 and the capsule chamber 200, resulting in a good sealing effect. Simultaneously, when the capsule chamber 200 slides, the first outer sealing... The outer lip 410 and the second outer sealing lip 420 can maintain a close fit with the mounting base 100 and the capsule chamber 200. Compared with the assembly method of interference fit between the outer sealing ring 400 and the capsule chamber 200 and the mounting base 100, the double sealing lip structure can greatly reduce the friction between the outer sealing ring 400 and the capsule chamber 200 and the mounting base 100. When the water flow pushes the capsule chamber 200 and the capsule 600 to move towards the cover plate 300, it can be achieved without a large water pressure, making the sliding of the capsule chamber 200 smoother. This prevents the capsule 600 and the capsule chamber 200 from getting stuck on the mounting base 100 due to the outer sealing lip being too tight. It ensures that the capsule chamber 200 can move smoothly under the push of the water flow to the front needle on the cover plate 300 to puncture the capsule 600, thereby ensuring the stable operation of the beverage brewing machine.

[0040] like Figure 1 and Figure 5As shown, the first outer sealing lip 410 and the second outer sealing lip 420 are integrally formed so that the axial section of the outer sealing ring 400 is V-shaped. Under its own elastic force, the ends of the first outer sealing lip 410 and the second outer sealing lip 420 near the liquid inlet chamber 140 extend in opposite directions, so that when there is no water in the first water storage gap 430, the first outer sealing lip 410 and the second outer sealing lip 420 can respectively maintain contact with the mounting base 100 and the capsule chamber 200. When water enters the first water storage gap 430, the water flow can directly impact the first outer sealing lip 410 and the second outer sealing lip 420, so that they respectively fit against the mounting base 100 and the capsule chamber 200. That is, whether the outer sealing ring 400 is impacted by water flow or not, it can maintain the seal between the outer wall of the capsule chamber 200 and the inner wall of the mounting base 100, resulting in a good sealing effect.

[0041] like Figure 3 As shown, in order to axially limit the outer sealing ring 400, this embodiment provides an outer sealing groove 210 on the outer side wall of the capsule chamber 200. The second outer sealing lip 420 is embedded in the outer sealing groove 210, and the first outer sealing lip 410 extends out of the outer sealing groove 210 to abut against the inner side wall of the mounting groove 110. When the capsule chamber 200 slides, the outer sealing ring 400 moves axially together with the capsule chamber 200, preventing the outer sealing ring 400 from disengaging from the capsule chamber 200 when it slides, and ensuring a stable seal between the outer sealing ring 400 and the mounting base 100. Preferably, the thickness of the second outer sealing lip 420 is greater than the thickness of the first outer sealing lip 410, so that the second outer sealing lip 420 is more firmly embedded in the outer sealing groove 210, avoiding excessive deformation when it slides with the capsule chamber 200, and ensuring a seal between the second outer sealing lip 420 and the capsule chamber 200.

[0042] In this embodiment, an inner sealing ring 500 is also provided on the inner wall of the capsule chamber 200. The inner sealing ring 500 includes a first inner sealing lip 510 and a second inner sealing lip 520. The sides of the first inner sealing lip 510 and the second inner sealing lip 520 away from the liquid inlet cavity 140 are connected to form a second water-retaining gap 530 with an opening facing the liquid inlet cavity 140 on the inner sealing ring 500. When the capsule 600 is placed in the capsule chamber 200, the side of the first inner sealing lip 510 near the liquid inlet cavity 140 abuts against the inner wall of the capsule chamber 200, and the side of the second inner sealing lip 520 near the liquid inlet cavity 140 abuts against the outer wall of the capsule 600, so as to form a second water-retaining gap 530 with an opening facing the liquid inlet cavity 140 on the inner sealing ring 500. When water flows from the inlet chamber 140 into the capsule 600, some water enters the gap between the capsule 600 and the capsule chamber 200. The inner sealing ring 500 seals this gap, preventing water from overflowing. Because a second water-holding gap 530 with an opening facing the inlet chamber 140 is formed between the first inner sealing lip 510 and the second inner sealing lip 520 on the inner sealing ring 500, when water impacts the inner sealing ring 500, water enters the second water-holding gap 530. The water in the second water-holding gap 530 pushes the first inner sealing lip 510 towards the capsule chamber 200, making the first inner sealing lip 510 fit tightly against the capsule chamber 200. At the same time, it pushes the second inner sealing lip 520 towards the capsule 600, making the second inner sealing lip 520 fit tightly against the capsule 600, thus improving the sealing performance between the inner sealing ring 500 and the capsule 600 and capsule chamber 200, resulting in a good sealing effect. After the capsule 600 is brewed, the inner sealing ring 500, no longer affected by the water flow, returns to its original position under its own elasticity, thereby reducing the contact area between the second inner sealing lip 520 and the capsule 600. This allows the user to easily remove the capsule 600 from the capsule compartment 200, improving the user experience.

[0043] like Figure 2 and Figure 4 As shown, the first inner sealing lip 510 and the second inner sealing lip 520 are integrally formed so that the axial section of the inner sealing ring 500 is V-shaped. The V-shaped axial section of the inner sealing ring 500 causes the first inner sealing lip 510 and the second inner sealing lip 520 to extend in opposite directions at the ends near the liquid inlet chamber 140 under their own elastic force. When the capsule 600 is inserted, the capsule 600 squeezes the second inner sealing lip 520 to improve the sealing effect between the second inner sealing lip 520 and the capsule 600.

[0044] To axially limit the inner seal ring 500, such as Figure 3As shown, in this embodiment, an inner sealing groove 220 is provided on the inner sidewall of the capsule compartment 200. A first inner sealing lip 510 is embedded in the inner sealing groove 220, and a second inner sealing lip 520 extends out of the inner sealing groove 220 to abut against the capsule 600. Preferably, the thickness of the first inner sealing lip 510 is greater than the thickness of the second inner sealing lip 520, so that the first inner sealing lip 510 is more securely embedded in the inner sealing groove 220, avoiding excessive deformation of the first inner sealing lip 510 when installing the capsule 600, and ensuring a seal between the first inner sealing lip 510 and the capsule compartment 200.

[0045] Preferably, the inner sealing groove 220 is positioned closer to the tail of the capsule 600 within the capsule chamber 200. That is, when the capsule 600 is placed inside the capsule chamber 200, the inner sealing groove 220 is positioned towards the side wall of the capsule 600, and the distance between the inner sealing groove 220 and the head of the capsule 600 is greater than the distance between the inner sealing groove 220 and the tail of the capsule 600. This ensures that the inner sealing ring 500 is sealed and connected near the tail of the capsule 600, effectively blocking water flow into the gap between the capsule 600 and the capsule chamber 200, thus preventing excessive liquid from entering between the capsule 600 and the capsule chamber 200.
