Description

Technical Field

[0001] This utility model relates to the technical field of coffee machines, and more particularly to a brewing funnel and a coffee machine. Background Technology

[0002] The brewing funnel is an essential component of a coffee machine. Its working principle is based on the drip coffee maker design. Water is heated from the tank into the heating element, the brewing head tampers with coffee grounds, and hot water flows through a one-way valve into the funnel, steeping the coffee grounds before dripping into the coffee cup. After this process, the coffee grounds are compacted within the funnel, forming a coffee puck. Currently, cleaning brewing funnels on the market requires customers to invert the funnel and tap it several times to remove the coffee puck, which is laborious and inconvenient. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] The technical problem this invention aims to solve is to provide a brewing funnel and coffee machine that, through a floating filter assembly design, can actively push coffee powder out of the receiving chamber, avoiding the problem of coffee powder adhering to the filter in traditional funnels. After use, simply press the filter assembly to easily remove coffee powder residue, eliminating the need for manual removal and greatly reducing cleaning time and workload. The design is ingenious yet relatively simple in structure, making it easy to manufacture and maintain. Users can easily clean the coffee powder with a simple press, making the operation simple and intuitive.

[0005] (II) Technical Solution

[0006] The present invention provides a brewing funnel to solve the above-mentioned technical problems. The funnel includes a funnel body and a filter assembly that is floatingly connected within the funnel body. The portion of the filter assembly placed within the funnel body cooperates with the inner wall of the funnel body to form a receiving cavity for receiving coffee powder. One end of the filter assembly, away from the receiving cavity, extends out of the funnel body. When the portion of the filter assembly extending out of the funnel body is subjected to a force toward the receiving cavity, it can exert a force on the coffee powder to detach it from the receiving cavity.

[0007] In some embodiments, the top of the funnel body is open and can be used with the brewing head to brew coffee powder into coffee liquid; a handle is detachably connected to the side wall of the funnel body for the user to hold.

[0008] The above solution, with its floating filter assembly design, can actively push coffee grounds out of the receiving chamber, avoiding the problem of coffee grounds sticking to the filter in traditional funnels. After use, simply press the filter assembly to easily remove coffee grounds residue, eliminating the need for manual removal and greatly reducing cleaning time and workload. The design is ingenious yet relatively simple in structure, making it easy to manufacture and maintain. Users can clean the coffee grounds with a simple press, making the operation simple and intuitive.

[0009] In some embodiments, the receiving cavity is composed of at least two cylindrical cavities with different inner diameters; and the inner diameter of the cylindrical cavity closer to the filter assembly is smaller than the inner diameter of the cylindrical cavity above it.

[0010] Specifically, after brewing, the brewing funnel is flipped over. After pressing the part of the filter assembly that extends out of the funnel body, an upward force is applied to the coffee powder, causing the coffee powder to move from the cylindrical cavity with a smaller inner diameter to the cylindrical cavity with a larger inner diameter. This creates a gap between the coffee powder and the inner wall of the receiving cavity, allowing the coffee powder to fall easily under its own weight.

[0011] Using the above solution, the different inner diameters design, after flipping and pressing the filter assembly, causes the coffee powder to shift during the pushing process, moving it from the small diameter cavity to the large diameter cavity; after the coffee powder moves to the large diameter cavity, a gap is created between it and the wall, allowing it to fall off naturally by gravity; the gradient design reduces the required pushing force and makes operation easier; it ensures that the coffee powder can completely leave the receiving cavity, avoiding residue.

[0012] In some embodiments, the portion of the filter assembly extending out of the funnel body forms a force-applying portion, and an elastic member is provided between the force-applying portion and the funnel body. The elastic member applies a force to the force-applying portion that always tends to be downward, so that the filter assembly has a tendency to always move away from the receiving cavity.

[0013] Using the above solution, the restoring force provided by the elastic element ensures that the filter assembly can automatically return to its initial position after the press is released; the constant downward force keeps the filter assembly close to the bottom of the receiving cavity during the brewing process, preventing displacement from affecting the seal, and thus ensuring that the filter assembly is in a stable working position during normal brewing; the resistance provided by the elastic element gives the pressing operation good tactile feedback; active force is required to activate the cleaning function to avoid accidental triggering.

[0014] In some embodiments, the portion of the filter assembly located within the funnel body has an upper limit portion. When the upper limit portion abuts against the bottom wall of the funnel body, the filter assembly is at its lowest height within the funnel body, which prevents the filter assembly from sinking excessively and ensures that it moves within a reasonable working range. At the same time, the limiting design ensures that the filter assembly and the funnel body maintain a good sealing fit.

[0015] In some embodiments, a button is connected to the portion of the filter assembly extending out of the funnel body, and the bottom of the button forms the force-applying portion.

[0016] In some embodiments, the button is connected by a threaded connection to the portion of the filter assembly that extends out of the funnel body.

[0017] Using the above solution, the button provides a clear pressing area, allowing users to apply more concentrated force. The threaded connection makes the button detachable, facilitating maintenance or replacement.

[0018] In some embodiments, the filter assembly includes a filter support, a filter element connected to one end of the filter support near the receiving cavity, and a seal connected to the outer peripheral wall of the filter support, wherein the outer wall of the seal is in a sealing fit with the inner wall of the funnel body.

[0019] The above solution ensures that the liquid flows out only through the filter screen during brewing, avoiding side leakage that could affect the extraction quality; the filter screen support provides a stable support structure; and the filter screen ensures good filtration performance and can be replaced individually, reducing maintenance costs.

[0020] In some embodiments, the bottom of the funnel body is provided with a perforation, and the filter support includes a rod that can extend out of the funnel body through the perforation, the rod being movable up and down along the central axis of the perforation.

[0021] In some embodiments, the end of the rod extending out of the funnel body is threadedly connected to the button; the upper limit portion is provided on the part of the rod placed on the funnel body; the funnel body is provided with a receiving groove for accommodating the elastic member below the perforation, one end of the elastic member abuts against the wall of the receiving groove, and the other end abuts against the wall of the button, so as to give the filter support a tendency to always move downward, so that the filter support will not float when the button is not pressed.

[0022] Using the above solution, the rod body ensures accurate up-and-down movement of the filter assembly through the perforated guide; the perforated guide prevents the filter assembly from shifting during movement; and axial movement ensures the precision and controllability of the operation.

[0023] In some embodiments, the filter support is provided with an opening communicating with the receiving cavity, and the funnel body is provided below the filter support with an outlet for coffee liquid to flow out. A water pipe structure is provided between the opening and the outlet, which can guide the coffee liquid to flow out quickly and in a concentrated manner, reduce dripping residue, and the clear flow channel structure facilitates subsequent cleaning work.

[0024] In some embodiments, the filter support includes a tray that can connect with the inner wall of the funnel body, and an extension wall formed by the outer wall of the tray extending downward. The outer peripheral wall of the extension wall is provided with a first mounting groove for installing the seal, the top of the tray is provided with a second mounting groove for receiving the filter, and the bottom of the tray extends downward at its middle position to form a rod that can penetrate the funnel body.

[0025] Specifically, the filter element is fixed to the tray by screws.

[0026] By adopting the above solution, the extension wall and the sealing components work together to enhance the sealing performance, prevent powder and slag from entering the lower layer, and fix the filter screen with screws to facilitate cleaning or replacement, thus extending its service life.

[0027] The solution adopted by this utility model to solve the above-mentioned technical problems is a coffee machine, characterized in that it includes the brewing funnel as described above.

[0049] like Figures 1-6 As shown, this utility model provides a brewing funnel, including a funnel body 100 and a filter assembly 200 that is floatingly connected within the funnel body 100. The portion of the filter assembly 200 placed within the funnel body 100 cooperates with the inner wall of the funnel body 100 to form a receiving cavity 101 for receiving coffee powder 500. One end of the filter assembly 200, facing away from the receiving cavity 101, extends out of the funnel body 100. When the portion of the filter assembly 200 extending out of the funnel body 100 is subjected to a force toward the receiving cavity 101, it can exert a force on the coffee powder 500, causing it to detach from the receiving cavity 101. In some embodiments, the top of the funnel body 100 is open and can cooperate with a brewing head to brew the coffee powder 500 into coffee liquid. A handle 400 is detachably connected to the side wall of the funnel body 100 for the user to grip. By adopting the above solution and through the design of the floating filter assembly 200, the coffee powder 500 can be actively pushed out of the receiving cavity 101, avoiding the problem of coffee powder 500 sticking to the filter in a traditional funnel. After use, simply press the filter assembly 200 to easily remove the coffee powder 500 residue, without the need to manually remove the residue, greatly reducing cleaning time and workload. The design is ingenious but the structure is relatively simple, making it easy to manufacture and maintain. Users can simply press to clean the coffee powder 500, making the operation simple and intuitive.

[0050] In some embodiments, the receiving cavity 101 is composed of at least two cylindrical cavities with different inner diameters; and the inner diameter of the cylindrical cavity near the filter assembly 200 in the receiving cavity 101 is smaller than the inner diameter of the cylindrical cavity above it. Specifically, after brewing, the brewing funnel is flipped over, and after pressing the portion of the filter assembly 200 extending out of the funnel body 100, an upward force is applied to the coffee powder 500, causing the coffee powder 500 to move from the cylindrical cavity with the smaller inner diameter to the cylindrical cavity with the larger inner diameter. This creates a gap between the coffee powder 500 and the inner wall of the receiving cavity 101, allowing the coffee powder 500 to easily fall out under its own weight. Using the above solution, the different inner diameter designs, after flipping and pressing the filter assembly 200, cause the coffee powder 500 to shift during the pushing process, moving it from the small diameter cavity to the large diameter cavity; after the coffee powder 500 moves to the large diameter cavity, a gap is created between it and the wall, allowing it to fall off naturally by gravity; the gradient design makes the required pushing force smaller and the operation easier; it ensures that the coffee powder 500 can completely detach from the receiving cavity 101, avoiding residue.

[0051] In some embodiments, the portion of the filter assembly 200 extending out of the funnel body 100 forms a force-applying part 201. An elastic element 202 is disposed between the force-applying part 201 and the funnel body 100. The elastic element 202 applies a force to the force-applying part 201 that always tends downward, so that the filter assembly 200 always tends to move away from the receiving cavity 101. With this design, the restoring force provided by the elastic element 202 ensures that the filter assembly 200 automatically returns to its initial position after the press is released; the always downward force keeps the filter assembly 200 pressed tightly against the bottom of the receiving cavity 101 during brewing, preventing displacement from affecting the seal, thereby ensuring that the filter assembly 200 is in a stable working position during normal brewing; the resistance provided by the elastic element 202 provides good tactile feedback during pressing; and the cleaning function requires active force to activate, avoiding accidental triggering. In some embodiments, the portion of the filter assembly 200 located within the funnel body 100 has an upper limit portion 203. When the upper limit portion 203 abuts against the bottom wall of the funnel body 100, the filter assembly 200 is at its lowest height within the funnel body 100, which can prevent the filter assembly 200 from sinking excessively and ensure that it moves within a reasonable working range. At the same time, the limiting design ensures that the filter assembly 200 and the funnel body 100 maintain a good sealing fit.

[0052] In some embodiments, a button 204 is connected to the portion of the filter assembly 200 extending out of the funnel body 100, and the bottom of the button 204 forms the force application portion 201. In some embodiments, the button 204 is connected to the portion of the filter assembly 200 extending out of the funnel body 100 via a threaded connection. With this design, the button 204 provides a clearly defined pressing area, allowing for more concentrated force application by the user, and the threaded connection makes the button 204 detachable, facilitating maintenance or replacement.

[0053] In some embodiments, the filter assembly 200 includes a filter support 205, a filter element 206 connected to one end of the filter support 205 near the receiving cavity 101, and a sealing element 207 connected to the outer peripheral wall of the filter support 205. The outer wall of the sealing element 207 seals against the inner wall of the funnel body 100. With this design, the sealing element 207 ensures that liquid flows out only through the filter during brewing, preventing side leakage from affecting the extraction quality; the filter support 205 provides a stable support structure; and the filter element 206 ensures good filtration and can be replaced individually, reducing maintenance costs. In some embodiments, the bottom of the funnel body 100 is provided with a perforation 102, and the filter support 205 includes a rod 2051 that can extend out of the funnel body 100 through the perforation 102. The rod 2051 can move up and down along the central axis of the perforation 102. In some embodiments, the end of the rod 2051 extending out of the funnel body 100 is threadedly connected to the button 204; the upper limit portion 203 is provided on the part of the rod 2051 placed on the funnel body 100; the funnel body 100 is provided with a receiving groove 104 for accommodating the elastic member 202 below the perforation 102, one end of the elastic member 202 abuts against the wall of the receiving groove 104, and the other end abuts against the wall of the button 204, so that the filter support 205 has a tendency to always move downwards, so that the filter support 205 will not float when the button 204 is not pressed. With the above solution, the rod 2051 ensures the accurate up and down movement of the filter assembly 200 through the guide of the perforation 102; the guide of the perforation 102 prevents the filter assembly 200 from deviating during movement; axial movement ensures the accuracy and controllability of operation.

[0054] In some embodiments, the filter support 205 is provided with an opening 2052 communicating with the receiving cavity 101, and the funnel body 100 is provided with an outlet 103 for coffee liquid to flow out below the filter support 205. A water pipe structure 300 is provided between the opening 2052 and the outlet 103, which can guide the coffee liquid to flow out quickly and in a concentrated manner, reduce dripping residue, and the clear flow channel structure facilitates subsequent cleaning work. In some embodiments, the filter support 205 includes a tray 2053 capable of contacting the inner wall of the funnel body 100, and an extension wall 2054 extending downward from the outer wall of the tray 2053. The outer peripheral wall of the extension wall 2054 is provided with a first mounting groove 2054a for mounting the seal 207. The top of the tray 2053 is provided with a second mounting groove 2053a for receiving the filter element 206. Furthermore, the bottom of the tray 2053 extends downward from its center to form a rod 2051 capable of penetrating the funnel body 100. Specifically, the filter element 206 is fixed to the tray 2053 with screws. Using this scheme, the extension wall 2054 cooperates with the seal 207 to enhance sealing, preventing powder and sludge from entering the lower layer. The screw fixing of the filter element 206 facilitates cleaning or replacement, extending its service life.
