Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to an anti-splash device for a coffee machine, and especially to a coffee machine incorporating the above-mentioned anti-splash device. Background Technology

[0002] During the operation of a coffee machine, if the machine head assembly is suddenly opened, the hot water inside the heating module and piping, which are in operation, will vaporize and spray out from the puncture needle, causing burns or other injuries to the operator. To address this issue, existing coffee machines incorporate an overflow valve in the piping to control the flow of hot water. However, hot water and steam often splash into the cavities of the machine components as they pass through the overflow valve. While adding an overflow valve significantly improves the safety of the coffee machine, it cannot completely eliminate the splashing problem. Therefore, a more reliable anti-splash device needs to be designed. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a splash-proof device that can achieve the splash-proof effect simply and efficiently.

[0004] One embodiment of this utility model provides a splash-proof device for a coffee machine, including a connecting rod, a sliding rod, and a fixed base. One end of the connecting rod is connected to the handle of the coffee machine head, and the other end of the connecting rod is connected to the sliding rod, so that the movement of the coffee machine head handle can drive the sliding rod to slide along the direction away from or towards the water pipe of the coffee machine through the connecting rod. The sliding rod is slidably mounted on the fixed base, which is used to fix it to the coffee machine head. One end of the sliding rod is provided with a pressure head for squeezing the water pipe. When the sliding rod slides away from the water pipe under the action of the coffee machine head handle, the pressure head releases the squeezing of the water pipe. When the sliding rod slides towards the water pipe under the action of the coffee machine head handle, the pressure head presses the water pipe to prevent hot water from overflowing from the water pipe.

[0005] Furthermore, a fixing block is provided at the end of the sliding rod away from the pressure head, and the connecting rod is connected to the sliding rod through the fixing block. Furthermore, the sliding rod is provided with a protruding baffle, which is arranged between the fixed seat and the pressure head. Furthermore, the splash guard also includes a spring, which is sleeved on the sliding rod and abuts against the fixed seat and the baffle.

[0006] Another embodiment of the present invention provides a coffee machine, including the above-mentioned anti-splash device and a machine head, wherein the anti-splash device is disposed inside the machine head.

[0007] Furthermore, the machine head includes a machine head handle for opening and closing the coffee machine, the machine head handle being located on one side of the machine head, one end of which is hinged to the machine head.

[0008] Furthermore, the machine head handle is connected to the sliding rod via a linkage, and the machine head handle is also used to drive the sliding rod to slide along the direction away from or towards the water pipe of the coffee machine via the linkage.

[0009] Furthermore, the sliding rod of the anti-splash device is located inside the machine head on the side near the machine head handle.

[0010] Furthermore, one end of the connecting rod is rotatably connected to the machine head handle, while the other end of the connecting rod is rotatably connected to the sliding rod.

[0011] Furthermore, the coffee machine also includes a water pipe disposed within the machine head, the water pipe being made of a flexible material, and at least a portion of the water pipe being disposed opposite the end of the sliding rod.

[0012] This utility model provides an anti-splash device for a coffee machine and the coffee machine itself. The anti-splash device includes a connecting rod, a sliding rod, a fixed base, a spring, a push plate, and a pressure head. The sliding rod is connected to the handle of the coffee machine head via the connecting rod. The handle of the coffee machine head drives the sliding rod to slide along the direction away from or towards the water pipe of the coffee machine via the connecting rod. When the sliding rod slides away from the water pipe under the action of the handle of the handle, the spring is compressed by the baffle plate, and the pressure head releases the pressure on the water pipe. When the sliding rod slides towards the water pipe under the action of the handle of the handle, the pressure head presses the water pipe, and the spring pops out and pushes the pressure head to further press the water pipe to prevent hot water from overflowing. This design uses the sliding rod movement mechanism inside the coffee machine head to press the water pipe, blocking the flow of hot water in the pipe, thereby quickly and conveniently achieving the effect of preventing hot water splashing.

[0018] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0019] like Figures 1 to 3 As shown, one embodiment of this application provides a splash-proof device 1 for a coffee machine 7, including a connecting rod 12, a sliding rod 11, a fixed base 13, and a spring 14. The connecting rod 12 connects the sliding rod 11 and the machine head handle 2, with one end rotatably connected to the machine head handle 2 of the coffee machine 7 and the other end rotatably connected to the sliding rod 11. When the machine head handle 2 moves, the connecting rod 12 can drive the sliding rod 11 to slide along the direction away from or towards the water pipe 3 of the coffee machine 7.

[0020] The mounting base 13 is fixed to the coffee machine head 6 of the coffee machine 7 and is used to install the sliding rod 11 and the spring 14. The sliding rod 11 is slidably mounted on the mounting base 6; specifically, one end of the sliding rod 11 is provided with a pressure head 16, which is used to squeeze the water pipe 3, and the other end is provided with a fixing block 17. The sliding rod 11 is connected to the connecting rod 12 through the fixing block 17. When the sliding rod 11 slides away from the water pipe 3 under the action of the machine head handle 2, the pressure head 16 releases the squeezing of the water pipe 3; when the sliding rod 11 slides towards the water pipe 3 under the action of the machine head handle 2, the pressure head 16 presses the water pipe 3 to prevent hot water in the water pipe 3 from overflowing. The sliding rod 11 is also provided with a protruding baffle 15, which is used to connect the sliding rod 11 to the spring 14 and is arranged between the mounting base 13 and the pressure head 16.

[0021] Spring 14 is used to push sliding rod 11 to further press water pipe 3 together with pressure head 16. Spring 14 is sleeved on sliding rod 11, with one end connected to fixed base 13 and the other end connected to baffle 15. When the machine head handle 2 is closed, the machine head handle 2 pushes sliding rod 11 to move away from water pipe 3. Baffle 15 also moves away from water pipe 3 along with sliding rod 11. That is, spring 14 is continuously compressed. Finally, sliding rod 11 is locked at the position furthest away from water pipe 3, and spring is also in a compressed state. When the handle 2 is opened, the handle 2 pulls the sliding rod 11 to move closer to the water pipe 3. The baffle 15 also moves closer to the water pipe 3 along with the sliding rod 11. The pressure head 16 at one end of the sliding rod 11 can then press against and squeeze the water pipe 3. At the same time, since the spring 14 is not locked by the handle 2, the spring 14 pops out, and its elastic force further pushes the pressure head 16 to press the water pipe 3, thereby blocking the flow of hot water in the water pipe 3 and achieving the effect of preventing hot water from splashing.

[0022] In summary, the above-described embodiments of this utility model provide an anti-splash device 1 for a coffee machine 7, comprising a connecting rod 12, a sliding rod 11, a fixed base 13, a spring 14, a push plate 15, and a pressure head 16. The sliding rod 11 is connected to the machine head handle 2 of the coffee machine 7 via the connecting rod 12. The machine head handle 2 drives the sliding rod 11 to slide along the direction away from or towards the water pipe 3 of the coffee machine 7 via the connecting rod 12. When the sliding rod 11 slides away from the water pipe 3 under the action of the machine head handle 2, the spring 14 is compressed by the baffle 15, and the pressure head 16 releases the pressure on the water pipe 3. When the sliding rod 11 slides towards the water pipe 3 under the action of the machine head handle 2, the pressure head 16 presses the water pipe 3, at which point the spring 14 pops out, pushing the pressure head 16 to further press the water pipe 3 to prevent hot water from overflowing from the water pipe 3. This design utilizes the sliding rod 11 motion mechanism inside the machine head 6 of the coffee machine 7 to press the water pipe 3, blocking the flow of hot water in the water pipe 3, thereby quickly and conveniently achieving the effect of preventing hot water from splashing.

[0023] like Figure 3As shown, another embodiment of the present invention provides a coffee machine 7, including the aforementioned anti-splash device 1 and a machine head 6, wherein the anti-splash device 1 is disposed inside the machine head 6. The machine head 6 includes a machine head handle 2, a water pipe 3, and a puncture needle 4; the machine head handle 2 is used to open and close the coffee machine 7, and is disposed on one side of the machine head 6, with one end hinged to the machine head 6. When opening and closing the machine head handle 2, the machine head handle 2 rotates around the hinge point. Specifically, the machine head handle 2 is connected to the sliding rod 11 via a connecting rod 12. One end of the connecting rod 12 is rotatably connected to the machine head handle 2, and the other end of the connecting rod 12 is rotatably connected to the sliding rod 11. Therefore, when the machine head handle 2 is in an opening and closing motion, the end of the connecting rod 12 connected to the machine head handle 2 rotates around the machine head handle 2. Since the length of the connecting rod 12 is constant, the end of the connecting rod 12 connected to the sliding rod 11 will also rotate. However, the pushing and pulling action of the machine head handle 2 causes the connecting rod 12 to move the sliding rod 11 in translation. Therefore, the movement of the machine head handle 2 can be converted into the horizontal movement of the sliding rod 11, so that the machine head handle 2 can drive the sliding rod 11 to slide along the direction away from or close to the water pipe 3 of the coffee machine 7 via the connecting rod 12. More specifically, when the handle 2 is closed, the handle 2 pushes the sliding rod 11 to the position furthest away from the water pipe 3 and locks the sliding rod 11 and the spring 14; when the handle 2 is opened, the handle 2 drives the sliding rod 11 to slide close to the water pipe 3 and squeezes the water pipe 3. At this time, the handle 2 has released the spring 14, and the spring 14 pops out because it is no longer under force, further pushing the sliding rod 11 to press the water pipe 3.

[0024] A water pipe 3 is disposed inside the machine head 6, with at least a portion of it positioned opposite the end of the sliding rod 11, allowing the anti-splash device 1 to compress the water pipe 3 within a certain range A. The water pipe 3 is made of an elastic material so that the pressure head 16 can easily press the pipe. A piercing needle 4, disposed inside the machine head 6, is used to pierce the coffee bag and inject hot water into the coffee, and is connected at one end to one end of the water pipe 3.

[0025] The coffee machine 7 also includes a heating module 5, which is located inside the coffee machine 7 and is used to heat the cold water in the coffee machine 7. It is connected to the piercing needle 4 through the water pipe 3 to deliver the hot water to the coffee bag that needs to be brewed.

[0026] The specific operation process of the coffee machine 7 to prevent splashing is as follows: Figure 1 As shown, with the handle 2 closed, it is parallel to the sliding rod 11. The handle 2, via the connecting rod 12, pushes the sliding rod 11 away from the water pipe 3. The baffle 15 on the sliding rod 11 then compresses the spring 14, moving the entire anti-splash device 1 away from the water pipe 3. The water pipe 3 is now in a free-flowing state, allowing hot water to flow smoothly into the piercing needle 4 and into the coffee bag. Figure 2As shown, when the handle 2 of the coffee machine is suddenly opened, the handle 2 pulls the sliding rod 11 to the end near the water pipe 3 via the connecting rod 12. The pressure head 16 at the end of the sliding rod 11 squeezes the water pipe 3, obstructing the flow of hot water in the water pipe 3. At the same time, the baffle 15 loses its locking effect on the handle 2, the spring 14 pops out, and further pushes the baffle 15 and the sliding rod 11 to squeeze the water pipe 3. The squeezing effect of the pressure head 16 on the water pipe 3 is enhanced, fully compressing the water pipe 3 and putting it in a broken circuit state. The hot water flow is interrupted and cannot reach the piercing needle 4. As the handle 2 of the coffee machine 7 is gradually opened to the maximum position, the squeezing effect of the anti-splash device 1 reaches its strongest, and hot water and steam cannot reach the piercing needle 4, thereby achieving the anti-splash effect and ensuring the safety of the operator. When the handle 2 of the machine head is closed again, the sliding rod 11 is pushed away from the end of the water pipe 3 by the connecting rod 12. This process is repeated to ensure that the water pipe 3 is always in a closed state when the handle 2 of the machine head is closed, and that the water pipe 3 is always in a closed state when the handle 2 of the machine head is open, so that hot water cannot splash out.

[0027] In summary, the coffee machine 7 provided by the above-described embodiments of this utility model includes the aforementioned anti-splash device 1 and a machine head 6. The machine head 6 includes a machine head handle 2, a water pipe 3, and a piercing needle 4. The machine head handle 2 is used to drive the sliding rod 11 to slide and locks the sliding rod 11 and spring 14 when closed. The water pipe 3 is made of elastic material and can be easily squeezed and restored. When the machine head handle 2 is open, the anti-splash device 1 presses the water pipe 3, preventing the hot water in the water pipe 3 from reaching the piercing needle 4, thereby achieving the anti-splash effect.

[0028] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
