Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, and in particular to a coffee machine that prevents dripping. Background Technology

[0002] Caffeine stimulates the central nervous system, inhibits adenosine production and promotes dopamine secretion, relieving fatigue and improving attention and mental agility. As a result, coffee is becoming increasingly popular, and coffee making requires a coffee machine.

[0003] In existing coffee machines, the coffee powder container needs to be installed on the brew head before brewing. After the coffee is extracted in the brew head, it flows into the coffee cup through the outlet tube at the bottom of the powder container, thus completing the coffee preparation. However, after a cup of coffee is prepared, the coffee machine needs to be turned off and the extraction stopped. But because there is still water in the brew head, and this water will continue to drip slowly downwards, after the coffee cup is removed, the intermittent extraction drips will contaminate the coffee machine base. In addition, when the coffee is extracted, the coffee liquid drips down through the outlet tube in a cylindrical shape with a large diameter. In addition, the distance between the bottom of the outlet tube and the coffee cup is relatively large. All of these factors can easily cause the coffee liquid in the coffee cup to splash. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a coffee machine that prevents dripping. The technical problem it aims to solve is that after the coffee extraction stops, there is still water in the brew head, and this water will continue to drip slowly downwards. When the coffee cup is removed, the intermittent extraction drips will contaminate the coffee machine base. In addition, when the coffee liquid drips through the dispensing tube, the coffee liquid has a cylindrical structure with a large diameter. In addition, the bottom of the dispensing tube is far from the coffee cup, all of which can easily cause the coffee liquid in the coffee cup to splash.

[0005] To address the aforementioned technical problems or one of the technical problems existing in the prior art, this utility model discloses a coffee machine that prevents dripping: it includes a coffee machine body and a brewing head installed on the coffee machine body. A powder hopper is provided below the brewing head. A first liquid outlet pipe is fixed and connected to the bottom of the powder hopper. A second liquid outlet pipe is sleeved on the outside of the first liquid outlet pipe. Multiple inclined liquid outlet pipes are fixed and connected to the bottom of the second liquid outlet pipe at equal intervals along its radial direction. A guide pipe is fixed and connected to the end of the inclined liquid outlet pipe away from the second liquid outlet pipe. A conical tube is fixed and connected to the bottom of the guide pipe. A disc is provided at the bottom of the second liquid outlet pipe. Multiple connecting plates are fixed at equal intervals along its radial direction on the outside of the disc. A column is fixed to one end of the connecting plate. A cone capable of blocking the conical tube is fixed to the top of the column. A coffee cup is placed on the base of the coffee machine body.

[0006] Furthermore, the inclination direction of the inclined outlet pipe gradually increases from the second outlet pipe towards the guide pipe, and the diameter of the conical pipe and the cone gradually increases from top to bottom.

[0007] Furthermore, a movable sleeve is slidably connected to the outside of the second liquid outlet pipe, and multiple connecting rods are fixed at equal intervals along the radial direction of the bottom of the movable sleeve, with the bottom of the connecting rods fixed to the disc.

[0008] Furthermore, a limiting groove and a positioning hole are provided on the outer side of the second liquid outlet pipe, a limiting block is fixed on the inner wall of the movable sleeve, the limiting block is slidably fitted in the limiting groove, a cylinder is fixed on the outer side of the movable sleeve, and a positioning post is slidably connected to the cylinder, the limiting block, and the movable sleeve, and the positioning post can be embedded in the positioning hole.

[0009] Furthermore, a pull rod is fixed to one end of the positioning post. The pull rod passes through the cylinder and slides inside the cylinder. A spring is sleeved on the outside of the pull rod. One end of the spring abuts against the positioning post, and the other end of the spring abuts against the inner wall of the cylinder.

[0010] Furthermore, two travel grooves are provided on the outer side of the first outlet pipe, and two locking blocks are fixed on the inner wall of the top of the second outlet pipe. The locking blocks are slidably engaged in the travel grooves. Multiple locking slots are provided at equal intervals on the outer side of the first outlet pipe, and the locking slots and travel grooves are connected. The locking blocks can be embedded in the locking slots.

[0011] Furthermore, a filter screen is fixed to the inner wall of the powder hopper, and multiple U-shaped blocks are fixed at equal intervals along the radial direction at the top of the powder hopper. Multiple baffles are fixed at equal intervals along the radial direction at the bottom of the brewing head, and the baffles can be embedded in the U-shaped blocks.

[0012] Compared with the prior art, the present invention has the following beneficial effects: By moving the second outlet tube downwards, tilting the outlet tube, guiding the liquid, and using the conical tube, the conical tube is brought closer to the rim of the coffee cup, shortening the distance between the guiding tube and the rim of the coffee cup. This reduces coffee splashing. Furthermore, the multiple tilted outlet tubes and guiding tubes break the coffee into multiple fine streams, reducing the impact force as it flows down, which also reduces coffee splashing. After the extracted coffee is discharged through the guiding tube, it falls onto the cone, where it is dispersed into a ring-shaped "waterfall." The coffee falls entirely inside the coffee cup. As the ring-shaped "waterfall" falls into the coffee, its impact force is further reduced, thus further minimizing coffee splashing.

[0013] The upward movement of the moving sleeve, connecting rod, disc, connecting plate, and cone causes the cone to block the conical tube, preventing subsequent dripping coffee liquid from contaminating the base of the coffee machine. It is worth mentioning that the cone has a dual function: firstly, it blocks the conical tube to prevent coffee liquid from dripping; secondly, when coffee liquid falls onto the cone, the cone can also disperse the coffee liquid into a ring-shaped "waterfall" to reduce coffee liquid splashing.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-8 The technical solution adopted by the present invention is as follows: a coffee machine that prevents dripping, including a coffee machine body 1 and a brewing head 2 installed on the coffee machine body 1. A powder container 3 is provided below the brewing head 2. A first liquid outlet pipe 4 is fixed and connected to the bottom of the powder container 3. A second liquid outlet pipe 5 is sleeved on the outside of the first liquid outlet pipe 4. Multiple inclined liquid outlet pipes 6 are fixed and connected to the bottom of the second liquid outlet pipe 5 at equal intervals along its radial direction. A guide pipe 7 is fixed and connected to the end of the inclined liquid outlet pipe 6 away from the second liquid outlet pipe 5. A conical pipe 8 is fixed and connected to the bottom of the guide pipe 7. A disc 10 is provided at the bottom of the second liquid outlet pipe 5. Multiple connecting plates 11 are fixed at equal intervals along its radial direction on the outside of the disc 10. A column 12 is fixed to one end of the connecting plate 11. A cone 13 that can block the conical pipe 8 is fixed to the top of the column 12. A coffee cup 9 is placed on the base of the coffee machine body 1.

[0019] Preferably, the inclined direction of the inclined liquid outlet pipe 6 gradually increases from the second liquid outlet pipe 5 towards the liquid guide pipe 7, the diameter of the conical pipe 8 and the cone 13 gradually increases from top to bottom, a filter screen 26 is fixed on the inner wall of the powder bin 3, a plurality of U-shaped blocks 27 are fixed at equal intervals along the radial direction of the top of the powder bin 3, a plurality of baffles 28 are fixed at equal intervals along the radial direction of the bottom of the brewing head 2, and the baffles 28 can be embedded in the U-shaped blocks 27, two travel grooves 23 are opened on the outer side of the first liquid outlet pipe 4, two locking blocks 25 are fixed on the inner wall of the top of the second liquid outlet pipe 5, the locking blocks 25 slide in the travel grooves 23, a plurality of slots 24 are opened at equal intervals on the outer side of the first liquid outlet pipe 4, and the slots 24 and the travel grooves 23 are connected, and the locking blocks 25 can be embedded in the slots 24.

[0020] During coffee brewing, the coffee bean powder container 3 is placed on the brew head 2. At this time, the U-shaped block 27 and the stop block 28 are misaligned. Then, the coffee bean powder container 3 is rotated so that the stop block 28 is embedded in the U-shaped block 27, that is, the coffee bean powder container 3 is fixed at the bottom of the brew head 2. Then, the coffee cup 9 is placed on the base of the coffee machine body 1. Then, the second liquid outlet tube 5 is rotated so that the locking block 25 moves out of the locking slot 24. After the locking block 25 moves into the stroke groove 23, the second liquid outlet tube 5 moves downward. When the second liquid outlet tube 5 moves downward, it moves the inclined liquid outlet tube 6, the guide tube 7, and the conical tube 8 downward, so that the conical tube 8 is close to the mouth of the coffee cup 9, and the coffee can be extracted. By shortening the distance between the liquid guide tube 7 and the mouth of the coffee cup 9, the occurrence of coffee splashing can be reduced. Furthermore, due to the setting of multiple inclined liquid outlet tubes 6 and liquid guide tubes 7, the coffee liquid can be broken into multiple fine streams, reducing the impact force when it flows down, which also reduces the occurrence of coffee splashing. After the extracted coffee liquid is discharged through the liquid guide tube 7, the coffee liquid will fall onto the cone 13. After falling onto the cone 13, the coffee liquid will be dispersed into a ring-shaped "waterfall" shape, and the landing point of the coffee liquid is inside the coffee cup 9. As the ring-shaped "waterfall" falls into the coffee liquid, its impact force will be further reduced, thus further reducing the occurrence of coffee splashing.

[0021] Preferably, a movable sleeve 15 is slidably connected to the outside of the second outlet pipe 5. Multiple connecting rods 14 are fixed at equal intervals along the radial direction of the bottom of the movable sleeve 15. The bottom of the connecting rods 14 is fixed to the disc 10. A limiting groove 16 and a positioning hole 19 are opened on the outside of the second outlet pipe 5. A limiting block 17 is fixed to the inner wall of the movable sleeve 15. The limiting block 17 is slidably fitted in the limiting groove 16. A cylinder 18 is fixed to the outside of the movable sleeve 15. A positioning post 20 is slidably connected to the cylinder 18, the limiting block 17, and the movable sleeve 15. The positioning post 20 can be embedded in the positioning hole 19. A pull rod 21 is fixed to one end of the positioning post 20. The pull rod 21 passes through the cylinder 18 and slides inside the cylinder 18. A spring 22 is sleeved on the outside of the pull rod 21. One end of the spring 22 abuts against the positioning post 20, and the other end of the spring 22 abuts against the inner wall of the cylinder 18.

[0022] After the coffee is prepared, first pull the lever 21 to move the positioning column 20 into the limiting block 17, then move the moving sleeve 15 upward. When the moving sleeve 15 moves upward, it moves the connecting rod 14, the disc 10, the connecting plate 11, and the cone 13 upward, so that the cone 13 blocks the conical tube 8. Then release the lever 21. At this time, under the rebound force of the spring 22, the positioning column 20 is driven into the positioning hole 19, that is, the moving sleeve 15 is fixed. At this time, the cone 13 is fixed, that is, the cone 13 can block the conical tube 8, avoiding the subsequent dripping coffee liquid from contaminating the base of the coffee machine body 1. It is worth mentioning that the cone 13 not only blocks the conical tube 8 to prevent the coffee liquid from dripping, but also disperses the coffee liquid into a ring-shaped "waterfall" when the coffee liquid falls on the cone 13 during coffee preparation, reducing the occurrence of coffee liquid splashing.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
