Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, specifically to a splash-proof coffee machine. Background Technology

[0002] Coffee has the functions of refreshing the mind, improving attention and reaction speed, improving mood, and relieving stress, so coffee is becoming more and more popular among people, and making coffee requires the use of a coffee machine.

[0003] Publication number CN221383276U discloses a coffee machine cleaning mechanism and a coffee machine. By fixing the disassembly and assembly components inside the coffee machine body, the filter plate is installed on the top of the groove at the bottom of the coffee machine body. The filter plate supports the cup that takes out the coffee. The dripping coffee flows into the groove at the bottom of the coffee machine body through multiple filter holes on the filter plate. The rinsing component cleans the groove at the bottom of the coffee machine body. The clogging component facilitates the drainage of wastewater from the groove at the bottom of the coffee machine body. The support component supports the coffee machine body and adjusts its height.

[0004] While the aforementioned existing technology facilitates the disassembly and cleaning of the filter plate on the coffee machine, it is essentially a remedial measure for when the filter plate is contaminated. The main reason for this is that there is a gap between the liquid outlet tube at the bottom of the powder container and the coffee cup. When the extracted coffee flows into the coffee cup through the liquid outlet tube, as the coffee level in the cup gradually rises, when the coffee level is close to the rim of the cup, the impact force of subsequent coffee flowing into the cup can cause coffee to splash, easily leading to the contamination of the coffee machine base and the filter plate on the base. Therefore, this application designs a method that can reduce coffee splashing and prevent coffee from splashing and contaminating the coffee machine base and the filter plate on the base. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a splash-proof coffee machine. The technical problem to be solved is that when the extracted coffee flows into the coffee cup through the dispensing pipe, the coffee liquid level in the coffee cup gradually rises. When the coffee liquid level is close to the mouth of the coffee cup, the impact force of subsequent coffee flowing into the coffee cup will splash coffee, which can easily cause the splashed coffee to contaminate the coffee machine base and the filter plate on the base.

[0006] To address the aforementioned technical problems or one of the technical problems existing in the prior art, this utility model discloses a splash-proof coffee machine, which includes a coffee machine body and a brewing head installed on the coffee machine body. A coffee cup is placed on the base of the coffee machine body. A powder container is provided below the brewing head. The bottom of the powder container is fixed and connected to a liquid outlet pipe. A filter screen is fixed to the inner wall of the powder container. A handle is fixed to the outer side of the powder container. A first liquid guide pipe is slidably connected to the outer side of the liquid outlet pipe. A second liquid guide pipe is slidably connected to the outer side of the first liquid guide pipe. A conical cover is fixed and connected to the bottom of the second liquid guide pipe. The conical cover can cover the coffee cup or bottle.

[0007] Furthermore, multiple baffles are fixed at equal intervals along the radial direction on the outer side of the bottom of the brewing head, and multiple U-shaped blocks are fixed at equal intervals along the radial direction on the outer side of the top of the powder bin. The powder bin can be fitted onto the outside of the brewing head, and the baffles can be embedded into the corresponding U-shaped blocks.

[0008] Furthermore, an annular plate is fixed at the bottom of the powder hopper. The annular plate is located outside the liquid outlet pipe, and the diameter of the annular plate is larger than the diameter of the liquid outlet pipe. The axes of the annular plate and the liquid outlet pipe coincide.

[0009] Furthermore, a connecting sleeve is fixed to and connected to the top of the first liquid guide tube. The diameter of the connecting sleeve is larger than the diameter of the annular plate. The connecting sleeve can be fitted over the annular plate. The axes of the connecting sleeve, the first liquid guide tube, and the second liquid guide tube coincide.

[0010] Furthermore, the outer side of the annular plate is provided with multiple travel grooves and slots at equal intervals along its radial direction, and the travel grooves and slots are connected. The inner wall of the connecting sleeve is fixed with multiple blocks at equal intervals along its radial direction. The blocks slide in the corresponding travel grooves and can be embedded in the corresponding slots.

[0011] Furthermore, a second retaining ring is fixed to the outer side of the bottom of the first liquid guide tube, and a first retaining ring is fixed to the inner wall of the top of the second liquid guide tube. The first retaining ring is slidably fitted to the outer side of the first liquid guide tube, and the inner ring diameter of the first retaining ring is smaller than the outer ring diameter of the second retaining ring.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. When coffee needs to be extracted, move the second liquid guide tube and the conical cover upwards, then place the coffee cup on the base of the coffee machine body, and then lower the conical cover. At this time, under the gravity of the conical cover and the second liquid guide tube, the conical cover will move down and cover the coffee cup. Then the extracted coffee liquid flows into the coffee cup through the liquid outlet tube, the first liquid guide tube, and the second liquid guide tube. Due to the setting of the conical cover, the coffee liquid can be effectively flipped and splashed, avoiding the splashed coffee liquid from contaminating the coffee machine base and the filter plate and other structures on the base.

[0013] 2: By setting up the stroke groove, the slot, the connecting sleeve, and the locking block, the locking block is aligned with the stroke groove, and then the connecting sleeve is placed on the annular plate. Then the connecting sleeve is rotated so that the locking block is embedded in the slot, thereby fixing the connecting sleeve and the annular plate. This method makes it easy to install the first liquid guide pipe and the second liquid guide pipe at the bottom of the powder hopper, thus facilitating subsequent disassembly and cleaning.

[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 this utility model is as follows: a splash-proof coffee machine, including a coffee machine body 1 and a brewing head 2 installed on the coffee machine body 1. A coffee cup 3 is placed on the base of the coffee machine body 1. A powder container 4 is provided below the brewing head 2. The bottom of the powder container 4 is fixed and connected to a liquid outlet pipe 5. A filter screen 6 is fixed to the inner wall of the powder container 4. A handle 7 is fixed to the outer side of the powder container 4. A first liquid guide pipe 8 is slidably connected to the outer side of the liquid outlet pipe 5. A second liquid guide pipe 9 is slidably connected to the outer side of the first liquid guide pipe 8. A conical cover 10 is fixed and connected to the bottom of the second liquid guide pipe 9. The conical cover 10 can cover the coffee cup 3.

[0019] Specifically, multiple baffles 11 are fixed at equal intervals along the radial direction on the outer side of the bottom of the brewing head 2, and multiple U-shaped blocks 12 are fixed at equal intervals along the radial direction on the outer side of the top of the powder bin 4. The powder bin 4 can be fitted onto the outside of the brewing head 2, and the baffles 11 can be embedded into the corresponding U-shaped blocks 12. An annular plate 13 is fixed at the bottom of the powder bin 4. The annular plate 13 is located outside the liquid outlet pipe 5, and the diameter of the annular plate 13 is larger than the diameter of the liquid outlet pipe 5. The axis of the annular plate 13 and the liquid outlet pipe 5 coincide.

[0020] Furthermore, a connecting sleeve 16 is fixed and connected to the top of the first liquid guide tube 8. The diameter of the connecting sleeve 16 is larger than the diameter of the annular plate 13. The connecting sleeve 16 can be fitted over the annular plate 13. The axes of the connecting sleeve 16, the first liquid guide tube 8, and the second liquid guide tube 9 coincide. Multiple travel grooves 14 and slots 15 are equally spaced along the radial direction on the outer side of the annular plate 13. The travel grooves 14 and slots 15 are connected. Multiple locking blocks 17 are fixed at equal intervals along the radial direction on the inner wall of the connecting sleeve 16. The locking blocks 17 slide in the corresponding travel grooves 14 and can be embedded in the corresponding slots 15.

[0021] It should be noted that by setting up the stroke groove 14, the slot 15, the connecting sleeve 16, and the locking block 17, the locking block 17 is aligned with the stroke groove 14, and then the connecting sleeve 16 is fitted onto the annular plate 13, so that the locking block 17 slides in the stroke groove 14. Then, the connecting sleeve 16 is rotated so that the locking block 17 is embedded in the slot 15, thereby fixing the connecting sleeve 16 and the annular plate 13. This method makes it convenient to install the first liquid guide tube 8 and the second liquid guide tube 9 at the bottom of the powder hopper 4, thus facilitating their subsequent disassembly and cleaning.

[0022] In addition, a second retaining ring 19 is fixed to the outer side of the bottom of the first liquid guide tube 8, and a first retaining ring 18 is fixed to the inner wall of the top of the second liquid guide tube 9. The first retaining ring 18 is slidably fitted to the outer side of the first liquid guide tube 8, and the inner ring diameter of the first retaining ring 18 is smaller than the outer ring diameter of the second retaining ring 19.

[0023] It should be noted that, since the inner diameter of the first retaining ring 18 is smaller than the outer diameter of the second retaining ring 19, the second liquid guide tube 9 is prevented from falling off the first liquid guide tube 8. Due to the setting of the conical cover 10, the diameter of the conical cover 10 is 15-20 cm, which is larger than the diameter of most common coffee cups 3, so that the conical cover 10 can cover the mouth of the common coffee cup 3.

[0024] During coffee brewing, the coffee bean powder container 4 is placed on the brew head 2. At this time, the U-shaped block 12 and the stop block 11 are misaligned. Then, by holding the handle 7 and rotating the coffee bean powder container 4, the stop block 11 is inserted into the U-shaped block 12, thus fixing the coffee bean powder container 4 at the bottom of the brew head 2. Coffee extraction can then begin. When extraction is needed, first align the locking block 17 with the travel groove 14, then place the connecting sleeve 16 onto the annular plate 13. Next, rotate the connecting sleeve 16 to insert the locking block 17 into the slot 15, thus aligning the connecting sleeve 16 and the annular plate 13. The three phases are fixed, and then the second liquid guide tube 9 and the conical cover 10 are moved upward. Then, the coffee cup 3 is placed on the base of the coffee machine body 1, and the conical cover 10 is lowered. At this time, under the gravity of the conical cover 10 and the second liquid guide tube 9, the conical cover 10 will move down and cover the coffee cup 3. Then, the extracted coffee liquid is guided into the coffee cup 3 through the liquid outlet tube 5, the first liquid guide tube 8, and the second liquid guide tube 9. Due to the setting of the conical cover 10, the coffee liquid can be effectively flipped and splashed, avoiding the splashed coffee liquid from contaminating the coffee machine base and the filter plate and other structures on the base.

[0025] 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.
