Description

Technical Field

[0001] This invention relates to a drip coffee machine and its drip filtering mechanism, and is a multifunctional drip coffee machine and its drip filtering mechanism. Background Technology

[0002] A coffee machine is an electrical appliance used for making coffee. They are generally divided into semi-automatic and fully automatic types. Semi-automatic coffee machines require manual operation for grinding, tamping, filling, brewing, and removing coffee grounds. Fully automatic coffee machines are fully automated, controlling the entire coffee brewing process from preheating and cleaning to grinding, tamping, brewing, and dispensing. They brew coffee according to scientific data and procedures, requiring only the touch of a button. Drip coffee, however, involves placing a filter paper inside a funnel, adding a cup's worth of coffee grounds to the filter paper, moistening the coffee grounds with water of the appropriate temperature, and then adding more water until a perfect cup of coffee is produced. Some existing drip coffee makers use drip coffee makers to make coffee. These generally include a coffee pot, coffee basket, and container, such as Chinese patent application number 201210026375.6, published on July 11, 2012, entitled "Multi-purpose drip coffee maker". Others mainly use a drip valve or drip valve to achieve the dripping operation and make drip coffee, such as Chinese patent application number 201710233071.X, published on July 14, 2017, entitled "A drip coffee maker". Some drip coffee makers also include a coffee bean hopper and a grinding device, such as Chinese patent application number 201520907689.6, authorized on May 11, 2016, entitled "A fully automatic bean-grinding drip coffee maker". However, the existing coffee basket fixing methods and spill containment functions in drip coffee machines often have some shortcomings. For example, traditional coffee basket fixing methods place the basket inside the machine, making it difficult to remove and clean during use, thus hindering convenient extraction. Furthermore, these baskets cannot be placed independently on the work surface; coffee grounds must be manually added to the filter tank during operation. Some designs use a basket-based system for automatic grounds collection. Additionally, the spill containment devices in existing drip coffee machines are often inconvenient to operate or have poor sealing performance, leading to coffee leakage, wasting coffee and easily soiling other parts of the machine. Therefore, an innovative design is needed to solve these problems and improve the ease of use and reliability of drip coffee machines. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide a multifunctional drip coffee machine and its drip filtering mechanism, thereby solving the technical problems of existing similar products, such as the relatively fixed coffee basket structure, inconvenient cleaning and extraction, inconvenient powder receiving and dripping operations, and suboptimal design of positioning, limiting, sealing, and flow-stopping structures and components. This objective is achieved through the following technical solution.

[0004] A drip filter mechanism for a multi-functional drip coffee machine includes a coffee basket containing a filter basket or filter paper. The key structural design feature is that the coffee basket is positioned within the filter pot of the filter assembly. A leak-proof valve assembly is located at the upper through-hole at the bottom center of the coffee basket, and this valve assembly is aligned with the opening at the bottom of the filter pot. When the filter assembly is placed in a lever-type fixing mechanism, the lever of the mechanism rotates to fix the filter assembly while simultaneously lifting and opening the leak-proof valve assembly at the bottom of the coffee basket. This opens the upper through-hole at the bottom of the coffee basket, aligning and communicating with the lower through-hole of the lever-type fixing mechanism and the top spout of the glass container. The lever of the lever-type fixing mechanism is installed at the front of the machine body. The lever rotates around the center of the lower through hole of the lifting column in the lever-type fixing mechanism. The shape and length of the lever should be designed in accordance with ergonomic principles to facilitate user operation. In the locked state, rotating the lever causes the lifting column to rise and fix the filter jug ​​while simultaneously opening the leak-proof valve of the filter tank assembly. When the lever rotates, it drives the lifting column to rise or fall through the connecting arm in the lever-type fixing mechanism, thereby fixing and unlocking the filter tank assembly.

[0005] The lever-type fixing mechanism has a lower rail for placing the filter tank assembly. The lower rail corresponds to an upper rail at the bottom of the filter pot of the filter tank assembly. The upper rail of the filter tank assembly leads into the lower rail of the lever-type fixing mechanism. This structural design, along with the lower rail at the bottom of the grinding system, prevents the filter tank assembly from rotating or wobbling when placed in the grinding system or the lever-type fixing mechanism.

[0006] The lower track of the lever-type fixing mechanism is provided with a positioning groove, and the bottom of the filter container of the filter tank assembly corresponding to the positioning groove is provided with a top rod positioning component. As the upper track of the filter tank assembly is inserted into the lower track of the lever-type fixing mechanism, the top rod of the top rod positioning component extends and is inserted into the positioning groove of the lever-type fixing mechanism until the upper track of the filter tank assembly and the lower track of the lever-type fixing mechanism are in place. At this point, the top rod of the top rod positioning component is positioned in the deep groove at one end of the positioning groove by the action of a top rod spring. The top rod of the top rod positioning component is set inside the top rod cover by the top rod spring, and the top rod, top rod spring, and top rod cover of the top rod positioning component are integrated as one unit. This top rod positioning component, utilizing a combination of a top rod and a spring, provides a damping feel and feedback upon placement of the filter tank assembly on the machine, greatly enhancing the user experience.

[0007] A magnetic column is installed at the other end of the inner side of the positioning groove. When the upper track of the filter tank assembly and the lower track of the lever-type fixing mechanism are guided into place, the magnetic column aligns and attracts the magnet of the magnet assembly at the bottom of the filter container of the filter tank assembly, triggering the reed switch sensor inside the lever-type fixing mechanism. The reed switch sensor is connected to the magnet assembly through a circuit. Thus, the filter tank assembly cannot operate if the magnet at the bottom of the filter container is not detected, preventing accidental activation. The magnetic column can also be made of iron. That is, when the lever raises the lifting column to the designated position, the locking structure automatically locks, ensuring that the filter tank assembly will not accidentally loosen or fall off during operation.

[0008] The lower through hole of the lever-type fixing mechanism is located at the center of the boss of the lifting column inside the lever-type fixing mechanism. The lower through hole of the lifting column is aligned with the center hole of the filter tank support base cover and the filter tank support base. The lifting column, the connecting arm, and the lever are connected and set inside the housing of the lever-type fixing mechanism formed by the filter tank support base cover and the filter tank support base. The connecting arm and the lever are integrated. One end of the lever extends out of the lever-type fixing mechanism. The outer diameter of the boss at the top of the lifting column inside the lever-type fixing mechanism is provided with a lifting column spring. The lifting column is driven to rotate and be lifted by the lever end extending out of the lever-type fixing mechanism and maintain its state.

[0009] The filter tank support base is provided with a corresponding shaped support metal piece, and the lever-type fixing mechanism is fixed to the machine body through the mounting column extending from the support metal piece.

[0010] The magnetic post of the lever-type fixing mechanism is located on the top side of the lower diameter of the lifting column's boss. Within the lever-type fixing mechanism, the outer diameter of the lower diameter of the lifting column has three equidistant inclined lugs. One side of the bottom of each inclined lug has an upper inclined surface. Below the inclined lugs of the lifting column, the inner circumference of the connecting arm has three lower inclined side grooves. The lower inclined side grooves of the connecting arm each have two end stop planes and a transition inclined surface connecting them, forming a single lower inclined surface. The upper inclined surface of the lifting column fits into the lower inclined surface of the connecting arm. The magnetic post is inserted into the positioning slot of the filter tray bracket base cover. Therefore, when the reed switch sensor detects the connection signal, the filter pot of the filter tray assembly is automatically positioned in the lever-type fixing mechanism, allowing the multi-functional drip coffee machine to power on and begin brewing, preventing burns to the user or spills of hot water or alcohol onto the machine or worktable.

[0011] The leak-proof valve assembly of the filter tank assembly includes a filter tank leak-proof valve spring, a filter tank leak-proof valve silicone, and a filter tank leak-proof valve. One end of the filter tank leak-proof valve is limited and sealed to the upper through hole at the center of the bottom of the filter pot by the filter tank leak-proof valve silicone. The sealing head of the other end of the filter tank leak-proof valve extends out of the upper through hole at the bottom of the filter pot, and the filter tank leak-proof valve spring is provided on the outer diameter of the rod. One end of the filter tank leak-proof valve spring abuts against the outside of the upper through hole at the bottom of the filter pot, and the other end of the filter tank leak-proof valve spring abuts against the sealing head of the filter tank leak-proof valve. The end face of the sealing head of the filter tank leak-proof valve has equidistantly distributed hollow holes, and the end face of the sealing head of the filter tank leak-proof valve abuts against and seals against the lower through hole of the lever-type fixing mechanism.

[0012] The filter basket of the filter tank assembly is provided with a lifting basket. The opening of the lifting basket is provided with a handle. The lifting basket and the filter basket are integrated. The two ends of the handle of the lifting basket are hinged to the inner diameter of the opening of the lifting basket. At the same time, the handle is limited to the limiting rib at the inner diameter of the opening of the lifting basket.

[0013] The filter basket and coffee basket of the filter tank assembly are flat-headed conical shapes with corresponding straight ends. The inner wall of the coffee basket is provided with equidistant ribs. The boss at the straight end of the filter basket at the bottom is integrally elliptical with the two sides. Ribs are provided on the inner walls of the two sides of the boss in the filter basket. The groove below the middle boss at the straight end of the filter basket at the bottom is aligned with the leak-proof valve assembly in the coffee basket below. The inner walls of the coffee basket and the filter basket are respectively provided with raised overflow holes.

[0014] The filter tank assembly has a stainless steel decorative shell on the outer diameter of the filter pot, and a handle is provided on one side of the filter pot.

[0015] The filter tank assembly has a notch on the other side of the handle of the filter pot. The bottom inner side of the top spray assembly of the filter tank corresponding to the notch has a raised edge. When the filter tank assembly is put into the lever-type fixing mechanism, the notch of the filter tank assembly and the raised edge of the top spray assembly of the filter tank are closed.

[0016] According to the above-mentioned multi-functional drip coffee machine with drip filtration mechanism, the drip coffee machine has a water tank system at the rear of the machine body, a grinding system on the upper side of one side of the front of the machine body, and a glass container, which is a coffee pot, on the lower side of the symmetrical other side of the front of the machine body. The water outlet pipe of the water tank system is connected to the water inlet on one side of the filter tank top spray assembly, and a valve controller is provided at the connection. A shower head is provided inside the filter tank top spray assembly. The filter pot of the filter tank assembly is placed below the powder outlet of the grinding system, or above the glass container on the symmetrical other side of the grinding system by a lever-type fixing mechanism. The characteristic is that when the filter tank assembly is placed on one side of the grinding system, the top basket opening of the coffee basket of the filter tank assembly is aligned with the powder outlet of the grinding system, and the coffee basket of the filter tank assembly is filled with powder. After the coffee basket of the filter tank assembly is filled with powder, the filter tank assembly is placed under the lever-type fixing mechanism below the filter tank top spray assembly. The machine body below the grinding system where the filter tank assembly is located has another lower rail. After the filter tank assembly is placed on the top spray assembly of the filter tank, turning the lever will start brewing coffee in a drip manner. That is, the above-mentioned leak-proof valve assembly is lifted and opened by rotating the lever on one side of the lifting column in the lower lever-type fixing mechanism. Coffee drips from the filter tank assembly into the glass container below. The lifting column in the lower lever-type fixing mechanism then resets, and the leak-proof valve assembly resets and closes. When the above-mentioned filter tank assembly is placed on the side of the grinding system, automatic powder collection is used, and automatic powder collection is completed.

[0017] This invention features a reasonable structural design, low overall size and height, simple and convenient operation, good stability, safety and sealing, and a wide range of applications; it is suitable for use as a multi-functional drip coffee maker, as well as for structural improvements to similar products.

[0030] The lower track of the aforementioned lever-type fixing mechanism is provided with a positioning groove 4011, and the bottom of the filter tank of the filter tank assembly corresponding to the positioning groove is provided with a top rod positioning component 106. When the upper track of the filter tank assembly is guided into the lower track of the lever-type fixing mechanism, the top rod 1061 of the top rod positioning component extends out and is guided into the positioning groove of the lever-type fixing mechanism until the upper track of the filter tank assembly and the lower track of the lever-type fixing mechanism are guided into place. The top rod of the top rod positioning component is positioned in the deep groove at one end of the positioning groove by the action of the top rod spring 1062. The top rod of the top rod positioning component is set in the top rod cover 1063 by the top rod spring. The top rod, the top rod spring, and the top rod cover of the top rod positioning component are connected as one unit. Meanwhile, a magnetic post 405 is provided at the other end of the inner side of the positioning groove. When the upper track of the filter tank assembly and the lower track of the lever-type fixing mechanism are guided into place, the magnetic post aligns with the magnet of the magnet assembly 105 at the bottom of the filter tank assembly, triggering the reed switch sensor 403 inside the lever-type fixing mechanism. The reed switch sensor is connected to the magnet assembly via a circuit. This structure serves as a locking mechanism to prevent accidental activation and ensures that the filter tank assembly will not accidentally loosen or fall off during operation.

[0031] The lower through hole of the aforementioned lever-type fixing mechanism is located at the center of the boss of the lifting column within the lever-type fixing mechanism. The lower through hole of the lifting column is aligned with the center holes of the filter tank support base cover 401 and the filter tank support base 409, respectively. The lifting column, connecting arm 407, and lever are connected and disposed within the housing of the lever-type fixing mechanism formed by the filter tank support base cover and the filter tank support base. The connecting arm and lever are integrated, with one end of the lever extending out of the lever-type fixing mechanism. A lifting column spring 402 is provided on the outer diameter of the boss at the top of the lifting column within the lever-type fixing mechanism. The lifting column is driven to rotate and lift through the lever end extending out of the lever-type fixing mechanism and maintain its position. The aforementioned filter tank support base cover and filter tank support base are connected to form the housing of the lever-type fixing mechanism. A correspondingly shaped bracket metal plate 406 is provided inside the filter tank support base. The lever-type fixing mechanism is fixed to the machine body through the mounting column extending from the bracket metal plate. The magnetic column of the lever-type fixing mechanism is located on the top of one side of the ring diameter below the boss of the lifting column. The outer diameter of the ring diameter below the boss of the lifting column in the lever-type fixing mechanism has three equally spaced inclined lugs 4041. The bottom side of the inclined lugs has an upper inclined surface. The inner ring of the connecting arm corresponding to the inclined lugs of the lifting column has three lower inclined side grooves 4071. The lower inclined side groove of the connecting arm has two end stop planes and a transition inclined surface connected together. The upper inclined surface of the lifting column fits with the lower inclined surface of the connecting arm. The magnetic column is inserted into the column hole at the positioning groove of the filter tank bracket base cover.

[0032] The aforementioned filter tank assembly includes a filter tank leak-proof valve spring 1071, a filter tank leak-proof valve silicone 1072, and a filter tank leak-proof valve 1073. One end of the filter tank leak-proof valve is sealed to the upper through hole at the center of the bottom of the filter pot by the filter tank leak-proof valve silicone. The sealing head of the other end of the filter tank leak-proof valve extends out of the upper through hole at the bottom of the filter pot, and the filter tank leak-proof valve spring is provided on the outer diameter of the rod. One end of the filter tank leak-proof valve spring abuts against the outside of the upper through hole at the bottom of the filter pot, and the other end of the filter tank leak-proof valve spring abuts against the sealing head of the filter tank leak-proof valve. The end face of the sealing head of the filter tank leak-proof valve is provided with equally spaced perforated holes, and the end face of the sealing head of the filter tank leak-proof valve abuts against and seals against the lower through hole of the lever-type fixing mechanism. The filter basket of the filter tank assembly includes a carrying basket 101. The carrying basket has a handle at its opening and is integrated with the filter basket. The handle 1011 is hinged at both ends to the inner diameter of the basket opening and is also limited by a limiting rib at the inner diameter of the basket opening. The filter basket and coffee basket of the filter tank assembly are flat-headed conical shapes with corresponding straight-line ends. The inner wall of the coffee basket has equidistant raised ribs. The protrusion 1021 at the straight-line end of the filter basket's bottom is integrally elliptical with both sides. Ribs are correspondingly provided on the inner walls of the two sides of the protrusion in the filter basket. The groove below the middle protrusion at the straight-line end of the filter basket's bottom aligns with the leak-proof valve assembly in the coffee basket below. Both the coffee basket and the filter basket have raised overflow holes on one side of their inner walls. The filter pot of the filter tank assembly has a stainless steel decorative shell on its outer diameter, and a handle is provided on one side of the pot's body. The filter tank assembly has a notch on the other side of the handle of the filter pot. The bottom inner side of the top spray assembly of the filter tank corresponding to the notch has a raised edge. When the filter tank assembly is put into the lever-type fixing mechanism, the notch of the filter tank assembly and the raised edge of the top spray assembly of the filter tank are closed.

[0033] During use, after the filter assembly automatically collects coffee grounds below the grinding system, attach it to the lever-type fixing mechanism on the machine body. Rotate the lever to the right to secure it, and simultaneously open the check valve of the flow-stopping device at the bottom of the filter assembly. The brewed coffee will drip into the glass container below. After brewing, remove the filter assembly again and place it below the grinding system to automatically collect more coffee grounds.

[0034] The advantages of this multi-functional drip coffee maker are as follows: 1) Stable fixation: The lever-type fixing mechanism firmly secures the filter assembly to the machine body, effectively preventing displacement during use and ensuring the stability and reliability of the coffee dripping process. 2) Convenient operation: Users can easily fix and unlock the filter assembly and open and close the check valve by simply operating the lever, making operation convenient and quick, greatly improving ease of use. 3) Excellent sealing: The sealing component of the check valve ensures that coffee liquid will not leak when the check valve is closed, avoiding waste and contamination, while also ensuring the quality of the coffee. 4) Cleanability: After use, the filter assembly can be removed for complete cleaning and rinsing with tap water. 5) Removability: The grinding system can be easily and completely removed and moved, and it automatically collects coffee grounds during grinding. 6) Excellent sealing: The sealing component of the check valve ensures that coffee liquid will not leak when the check valve is closed, avoiding waste and contamination, while also ensuring the quality of the coffee. 7) Overall performance improvement: The application of the corresponding device improves the overall performance and user experience of the drip coffee machine, making it more stable, reliable and convenient to use, and meeting users' needs for high-quality coffee making.

[0035] In summary, this multi-functional drip coffee machine includes a lever-type fixing mechanism, a flow-stopping device, and a detachable filter assembly and grinding system. This allows for a stable fixation of the filter assembly, which serves as the coffee basket, and convenient flow-stopping operation, while ensuring good sealing performance and improving the overall performance and user experience of the drip coffee machine.
