Description

Technical Field

[0001] This utility model relates to the field of coffee machine cleaning accessories, specifically a coffee machine capsule flow-boosting cup sleeve. Background Technology

[0002] A capsule coffee machine is a convenient coffee-making device. By inserting a pre-packaged coffee capsule into the machine, users can quickly make a cup of coffee simply by pressing a button. It is easy to operate, suitable for home or office use, and especially ideal for users who value efficiency and consistent taste. Capsule coffee machines are typically compact in design, taking up little space, and require no complicated grinding or tamping steps, making them widely popular.

[0003] However, in actual use, the internal structure of the machine, such as the needle at the extraction head (used to pierce the capsule) and the spout, is prone to accumulating coffee grounds and limescale, requiring regular cleaning. If cleaning is not timely, it may affect the taste of the coffee and even cause machine malfunction. Existing coffee capsule cleaning methods typically involve injecting water to mix with the cleaning agent (soluble solids) inside the capsule, forming a cleaning solution. Continuous water injection raises the level of the cleaning solution, wetting the bottom of the capsule coffee machine and the spout. This wetting method cleans the bottom of the extraction head, but it is ineffective at removing coffee grounds. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a coffee machine capsule cleaning and flow-enhancing cup sleeve, which has the advantages of quick installation / removal, good fastening effect, and the ability to guide the cleaning solution to rinse away residue on the bottom surface of the extraction head, effectively solving the problems existing in the prior art.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A coffee machine cleaning capsule flow-enhancing cup sleeve includes a capsule sleeve and a top cover. The capsule sleeve and top cover form a cavity that encloses the coffee machine cleaning capsule, fixing the capsule within the cavity and allowing smaller coffee capsules to be compatible with the same coffee machine. The bottom of the capsule sleeve has an opening for the bottom of the cleaning capsule to protrude, accommodating cleaning capsules of different heights. The top cover has a water inlet for the extraction head to enter the capsule, ensuring accurate water flow. This allows the water to mix with the cleaning agent (soluble solids) inside the capsule to form a cleaning solution. Continuous water flow increases the pressure inside the capsule. The top cover also features a flow-enhancing function. The pressure module is equipped with a flow guide column and a spray nozzle. The flow guide column can be used to pierce the sealing film on the top of the coffee machine cleaning capsule to form an opening for the cleaning solution to flow out. When the coffee machine is working, the pressure module can guide the cleaning solution in the coffee machine cleaning capsule to rise through the pierced opening via the flow guide column, and enhance the flow rate of the cleaning solution through the inertia generated by the rotation of the capsule sleeve driven by the coffee machine. This causes the cleaning solution to be sprayed out from the spray nozzle to impact the extraction head, thereby knocking off the adhering substances on the extraction head. After the top cover is closed with the capsule sleeve, a liquid collection chamber can also be formed on the side wall of the coffee machine cleaning capsule to collect the overflowing cleaning solution and prevent the cleaning solution from flowing out of the flow booster cup sleeve from the bottom.

[0007] In one embodiment, the top cover sidewall tapers from top to bottom, making it easier and more precise to insert into the capsule sleeve. The inner wall of the top cover is straight, allowing it to completely cover the upper surface of the coffee machine cleaning capsule. The top cover also has a guide chamber for guiding the cleaning solution, which can collect the rising cleaning solution. The guide column is located in the guide chamber, which guides the cleaning solution to flow into the guide chamber. The upper end of the guide chamber is a spray chamber. The spray hole connects the guide chamber and the spray chamber. The spray chamber can disperse the cleaning solution, enhance its impact force, and enable the cleaning solution to effectively clean the bottom surface of the extraction head.

[0008] In one embodiment, the number of flow chambers and flow columns is the same, ensuring that the cleaning solution discharged from the flow columns can enter the flow chambers. Both are arranged in a circular pattern with the water inlet as the center, ensuring that the flow-enhancing cup sleeve can rotate smoothly during use. The flow columns are conical in shape, which facilitates piercing the sealing film on the top of the coffee machine cleaning capsule.

[0009] In one embodiment, the flow chamber has at least one flow guide column and at least one spray hole. The spray holes are evenly distributed on both sides of the flow guide column, so that the cleaning solution can be sprayed out from multiple points to effectively clean the bottom surface of the extraction head. The centers of the flow guide column, the spray hole and the spray hole form a triangle. The spray hole is set on both sides of the flow guide column to ensure that the rising cleaning solution can be sprayed out evenly multiple times.

[0010] In one embodiment, the outer side wall, inner side wall, and connecting wall of the flow guide chamber are arc-shaped, forming a rounded fan shape. The rounded corner design facilitates the inertial guidance of the cleaning solution to smoothly slide onto the side wall of the flow guide chamber towards the spray hole. The flow guide column is located on the side close to the outer side wall, allowing the cleaning solution to rise. The spray hole is located on the side close to the inner side wall.

[0011] In one embodiment, the liquid-spinning chamber is fan-shaped, and the orientation of the liquid-spinning chamber is the same as that of the flow-guiding chamber, that is, the two side walls of the liquid-spinning chamber expand outward, which facilitates the cleaning solution to be thrown out along the rotation direction to clean the extraction head. The middle part of the liquid-spinning chamber is also provided with a blocking block, which can collide with the cleaning solution, giving the cleaning solution a stronger impact force, so that the cleaning solution washes the bottom surface of the extraction head and cleans away condensates, flocculents and other residues.

[0012] In one embodiment, the liquid-splashing chamber and the flow-guiding chamber are one-to-one. The liquid-splashing chambers are separated by a separation wall, dividing the liquid into multiple parts for simultaneous cleaning. This restricts the movement space of the cleaning liquid, allowing it to impact the bottom of the extraction head when it has greater inertia. The separation wall extends outward from the side wall of the water inlet, and both are of the same height and are integrally molded. After fitting with the bottom surface of the extraction head, it ensures that the connection between the two is tight. The outer walls of two adjacent liquid-splashing chambers are connected to form a covering ring. The covering ring can fit against the side of the bottom surface of the extraction head, covering the components on the bottom surface of the extraction head and ensuring the cleaning effect.

[0013] In one embodiment, a fixing groove is provided on the side wall of the top cover, and an insertion post is provided inside the capsule sleeve to be inserted into the fixing groove. After insertion, the top cover can be firmly embedded in the capsule sleeve to lock the coffee machine cleaning capsule. The capsule sleeve is composed of an outer sleeve and an inner sleeve. The bottom of the outer sleeve is in an inwardly tapering arc shape, and the inner sleeve is ring-shaped and its bottom is connected to the outer sleeve to form a liquid collection cavity. The side wall of the coffee machine cleaning capsule fits against the inner wall of the inner sleeve to complete the fixation of the coffee machine cleaning capsule.

[0014] In one embodiment, the top of the outer sleeve is provided with a support surface, which allows the flow-boosting cup sleeve to be securely placed in the capsule placement slot of the coffee machine, facilitating the rotation of the flow-boosting cup sleeve by the coffee machine. The height of the inner sleeve is lower than the height of the outer sleeve, and when the top cover is closed with the capsule sleeve, the height of the top cover is not higher than the height of the outer sleeve, so that the outer sleeve and the top cover form a space for the extraction head to be inserted, so that the side walls and bottom surface of the extraction head are completely covered.

[0015] In one embodiment, the water inlet is located at the center of the top cover, and the distance between the center of the spray hole and the center of the water inlet does not exceed half the radius of the top cover, so that the liquid sprayed from the spray hole collides with the bottom of the extraction head during the rising process, thereby ensuring the cleaning effect.

[0045] Example

[0046] Please see Figure 1-12 This is a coffee machine cleaning capsule flow booster sleeve, comprising a capsule sleeve 1 and a top cover 2. The capsule sleeve 1 and the top cover 2 form a cavity 3 that encloses the coffee machine cleaning capsule. The bottom of the capsule sleeve 1 has an opening 4 for the bottom of the coffee machine cleaning capsule to be exposed. The top cover 2 has a water inlet 5 for the extraction head to enter water. In use, the coffee machine cleaning capsule is inserted from the top of the capsule sleeve 1, allowing it to enter the cavity 3. Then, the top cover 2 is closed to form a flow booster sleeve. The flow booster sleeve is then placed in the capsule placement area of ​​the coffee machine, and the coffee machine is closed. At this time, the water injection port in the middle of the extraction head can be inserted through the water inlet 5 to puncture the sealing film of the coffee machine cleaning capsule. The top cover 2 also has a pressure boosting module, which has a guide column 6 and a spray hole 7. When the top cover 2 is closed, the guide column 6 punctures the sealing film on the top of the coffee machine cleaning capsule. When the coffee machine is started, the pressure boosting module can... The guide column 6 guides the mixed cleaning solution in the coffee machine cleaning capsule upwards, and the inertia enhances its flow rate, causing the liquid to be sprayed out from the spray hole 7 and impact the extraction head. After the top cover 2 is closed with the capsule sleeve 1, a liquid collection chamber 8 can also be formed on the side wall of the coffee machine cleaning capsule. When the cleaning operation is started, the coffee machine starts and rotates with the flow-enhancing cup sleeve, generating centrifugal force. At the same time, the extraction head begins to inject water. The water flow mixes with the cleaning agent (soluble solid) in the coffee cleaning capsule to form a cleaning solution. When the water flow fills the coffee machine cleaning capsule, the extraction head continues to inject water. The cleaning solution in the coffee machine cleaning capsule is pushed by the continuously injected water flow and driven by the centrifugal force of the coffee machine's rotation. The solution in the coffee machine cleaning capsule rises along the guide column and is sprayed upwards from the spray hole 7, hitting the bottom surface of the extraction head, thus achieving the effect of wetting and rinsing the extraction head with the cleaning solution.

[0047] Preferably, the sidewall of the top cover 2 tapers from top to bottom, the inner wall of the top cover 2 is straight, and the top cover 2 is also provided with a guide chamber 9 for guiding the cleaning solution. The guide column 6 is located in the guide chamber 9, the upper end of the guide chamber 9 is a liquid-throwing chamber 10, and the spray hole 7 connects the guide chamber 9 and the liquid-throwing chamber 10.

[0048] By adopting the above technical solution, when the cleaning solution rises along the guide column 6 by thrust and centrifugal force, it will first enter the guide chamber 9. After passing through the guide chamber 9, the cleaning solution is guided to the spray hole 7 and then enters the liquid-spraying chamber 10 from the spray hole 7. The bottom part of the extraction head that needs to be cleaned is covered by the liquid-spraying chamber 10. Therefore, the cleaning solution sprayed from the spray hole 7 wets and impacts the extraction head in the liquid-spraying chamber 10.

[0049] Preferably, the number of flow guide chambers 9 and the number of flow guide columns 6 are the same, and both are arranged in a circular pattern with the water inlet 5 as the center, and the flow guide columns 6 are conical.

[0050] By adopting the above technical solution, the flow guide chamber 9 and the flow guide column 6 correspond one-to-one, ensuring that the rising cleaning solution can flow accurately into the flow guide chamber. Moreover, the two are arranged in a circumferential array around the water inlet hole as the center, which works in conjunction with the centrifugal force generated by the coffee machine to more easily draw the cleaning solution out of the coffee machine cleaning capsule.

[0051] Preferably, the flow guide chamber 9 has at least one flow guide column 6 and at least one or two liquid injection holes 7, the liquid injection holes 7 are evenly distributed on both sides of the flow guide column 6, and the centers of the flow guide column 6 and the liquid injection holes 7 form a triangle.

[0052] By adopting the above technical solution, the centrifugal force generated when the coffee machine starts up causes the cleaning solution to rise along the guide column 6. After entering the guide chamber 9, it breaks away from the guide column under the action of inertia, flows to the spray hole 7, and finally flows out from the spray hole 7. The spray hole 7 is set on both sides of the guide column 6. No matter which direction the coffee machine drives the flow-increasing cup sleeve to rotate, it can ensure that the outlet hole 7 sprays out the cleaning solution powerfully.

[0053] Preferably, the outer sidewall 11, inner sidewall 12, and connecting wall 13 of the flow guide chamber 9 are arc-shaped, forming a rounded fan shape. The flow guide column 6 is located on the side close to the outer sidewall 11, and the liquid spray hole 7 is located on the side close to the inner sidewall 12.

[0054] By adopting the above technical solution, when the cleaning solution rises along the guide column 6 and enters the guide chamber 9, it flows along the connecting wall 13 to the spray hole 7 under the action of centrifugal force. The connecting wall 13 is arc-shaped, which makes the cleaning solution flow more smoothly to the spray hole 7.

[0055] Preferably, the liquid-spinning chamber 10 is fan-shaped, and the orientation of the liquid-spinning chamber 10 is the same as that of the guide chamber 9, that is, the two side walls of the liquid-spinning chamber 10 expand outward. The middle part of the liquid-spinning chamber 10 is also provided with a blocking block 14, which can collide with the cleaning solution to flush the bottom surface of the extraction head.

[0056] By adopting the above technical solution, when the cleaning solution flows out of the spray hole 7, it will enter the liquid-spraying chamber 10. Under the action of inertia, the cleaning solution will collide with the blocking block 14 or the side wall of the liquid-spraying chamber 10. Since the upper surface of the top cover 2 is in contact with the bottom surface of the extraction head, and the height of the liquid-spraying chamber is higher than the height of the various components on the bottom surface of the extraction head, the cleaning solution that collides in the liquid-spraying chamber 10 will also collide with the extraction head and its bottom components, thus achieving the effect of cleaning solution rinsing the bottom of the extraction head.

[0057] Preferably, the liquid-throwing chamber 10 and the flow-guiding chamber 9 are in one-to-one correspondence. The liquid-throwing chambers 10 are separated by a separation wall 15. The separation wall 15 extends outward from the side wall of the water inlet 5 and the two are at the same height. The outer walls of two adjacent liquid-throwing chambers 10 are connected to each other to form a covering ring 16. The covering ring 16 can fit against the bottom side of the extraction head to cover the components on the bottom surface of the extraction head.

[0058] By adopting the above technical solution, the top surface of the top cover 2 is evenly divided into several liquid-spraying chambers 10 by the separation wall 15, and each liquid-spraying chamber 10 is provided with a blocking block 14, so that the introduced cleaning solution can only collide with the separation wall 15, the blocking block 14 and the bottom surface of the extraction head and the components thereon in a limited space, thereby achieving an effective cleaning effect.

[0059] Preferably, the top cover 2 has a fixing groove 17 on its side wall, and the capsule sleeve 1 has an insertion post 18 that is inserted into the fixing groove 17. The capsule sleeve 1 is composed of an outer sleeve 19 and an inner sleeve 20. The bottom of the outer sleeve 19 is an inwardly tapering arc shape, and the inner sleeve 20 is annular and its bottom is connected to the outer sleeve 19. The side wall of the cleaning capsule is in contact with the inner wall of the inner sleeve 20.

[0060] By adopting the above technical solution, when the top cover 2 is inserted into the capsule sleeve 1, the fixing groove 17 and the insertion post 18 should be aligned. After insertion, the two form a tight connection, so that the top cover 2 and the capsule sleeve 1 cannot be deflected. After closing, the bottom surface of the top cover 2 is simultaneously closed on the inner sleeve 20, and the side wall is in contact with the inner wall of the inner sleeve 20. The three form the liquid collection cavity 8.

[0061] Preferably, the top of the outer sleeve 19 is provided with a support surface 21, the height of the inner sleeve 20 is lower than the height of the outer sleeve 19, and when the top cover 2 is closed with the capsule sleeve 1, the height of the top cover 2 is not higher than the height of the outer sleeve 19.

[0062] By adopting the above technical solution, when the capsule sleeve 1 is inserted, the tray 21 can support the capsule sleeve 1 so that it does not slip off the capsule placement area of ​​the coffee machine. The tray 21 also helps the user to remove the flow cup sleeve. Since the bottom of the capsule sleeve 1 is provided with an opening 4 for the coffee machine to clean the bottom of the capsule, when the top cover 2 is closed with the capsule sleeve 1, the height of the top cover 2 is not higher than the height of the outer sleeve 19, so as to ensure that the fit between the extraction head and the top cover 2 is appropriate.

[0063] Preferably, the water inlet 5 is located at the center of the top cover 2, and the distance between the center of the spray hole 7 and the center of the water inlet 5 does not exceed half the radius of the top cover 2.

[0064] By adopting the above technical solution, the liquid sprayed from the spray hole 7 can collide with the bottom of the extraction head during the rising process. The cleaning solution has the greatest impact force during the rising stage, which can better clean the bottom surface of the extraction head and the various components on it.

[0065] Working principle: The guide column 6 punctures the sealing film of the coffee cleaning capsule, allowing the cleaning solution to rise along the guide column 6 and flow into the guide chamber 9 under the combined action of the pressure of the water injected by the coffee machine and the centrifugal force generated by the rotation of the capsule sleeve. It is then sprayed out through the spray hole 7, impacting the bottom surface of the extraction head. After impact, it falls into the liquid-spraying chamber 10, where it collides with the blocking block 14 under the action of centrifugal force, impacting the bottom surface of the extraction head again. This achieves the effect of multiple impacts to clean the bottom surface of the extraction head and its components.

[0066] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
