Description

Technical Field

[0001] This utility model relates to the field of brewing head technology, specifically a metal brewing head for beverage machines that prevents clogging. Background Technology

[0002] As is well known, anti-clogging metal brewing heads for beverage machines are metal parts used in beverage machines (such as coffee machines, milk tea machines, etc.) to mix hot water or solutions with raw materials (coffee powder, tea powder, etc.) for brewing. They are shaped like spoons, used to hold coffee powder, and can be connected to the coffee machine. Essentially, they are a simplified form of a split metal brewing head, commonly found in semi-automatic coffee machines, pour-over auxiliary equipment, etc. This split design makes it easy to clean and can effectively prevent the brewing head from clogging.

[0003] In existing anti-clogging metal brewing heads for beverage machines, the filter screen is mostly a fixed design that cannot be separated from the main body of the brewing head. This makes it difficult to clean the filter screen thoroughly during cleaning, which easily creates hygiene dead spots. Moreover, if the filter screen is damaged after long-term use, it cannot be replaced separately, and the entire device must be replaced, which significantly increases the subsequent maintenance and usage costs. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a clog-resistant metal brewing head for beverage machines.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a metal brewing head for a beverage machine that prevents clogging, comprising a housing, a connecting ring, a filter screen, an inner ring, and a connecting mechanism. The connecting ring is disposed on the top of the housing, and its outer wall is threaded. One side of the housing is fixedly connected to a handle. A first sealing ring is fixedly connected to the top of the connecting ring. A second sealing ring is provided on the inner wall of the housing and is fixedly connected to the inner wall of the housing. The filter screen is connected to the housing through the connecting mechanism, and the filter screen extends into the housing. The top of the filter screen abuts against the bottom of the second sealing ring. Several connecting mechanisms are provided, each including a connecting block, a limiting block, a T-slot, and an I-shaped block. One end of the connecting block is connected to the bottom of the filter screen, and the other end of the connecting block contacts the bottom of the housing. One end of the limiting block is connected to the bottom of the housing, and the other end of the limiting block contacts the bottom of the connecting block. Both the limiting block and the connecting block are provided with T-slots. Both ends of the I-shaped block extend into the T-slots provided by the limiting block and the connecting block, respectively. In the groove, the inner ring extends into the housing and contacts the inner wall of the housing. The bottom of the inner ring contacts the top of the second sealing ring. A magnetic block is provided on the top of the housing. One end of the magnetic block is fixedly connected to the top of the housing, and the other end of the magnetic block attracts the inner ring.

[0006] To improve stability, this utility model is improved by having several of the aforementioned connecting mechanisms arranged symmetrically.

[0007] To improve the anti-slip effect, the present invention is improved by providing a silicone layer on the outer wall of the handle, the silicone layer being fixedly connected to the outer wall of the handle, and the outer wall of the silicone layer having several anti-slip grooves.

[0008] To improve stability, this utility model is improved by providing two magnetic blocks arranged symmetrically.

[0009] To improve stability, this invention is improved by matching the I-shaped block with the T-shaped groove.

[0010] To improve the connection effect, the present invention is improved by fixing the handle to the outer wall of the housing.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a clog-resistant metal brewing head for beverage machines, which has the following beneficial effects: This anti-clogging beverage machine uses a metal brewing head with a detachable filter design. Through precise matching of I-shaped blocks and T-slots and symmetrically distributed connecting mechanisms, the filter can be quickly installed and removed, facilitating comprehensive cleaning and individual replacement, avoiding the need to replace the entire device and reducing operating costs. The inner ring is made of food-grade martensitic stainless steel, and with two symmetrically arranged magnetic blocks, it achieves stable adsorption, ensuring a tight seal with the housing to prevent powder leakage, while also allowing for individual cleaning and reducing cleaning dead spots. The threaded design of the connecting ring matches the first sealing ring to ensure a tight seal with the coffee machine. The silicone layer and anti-slip texture on the outer wall of the handle enhance grip stability and make operation safer. The overall structure combines anti-clogging, easy cleaning, and convenient operation, significantly improving the practicality and durability of the equipment. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4A clog-resistant metal brewing head for a beverage machine includes a housing 1, a connecting ring 2, a filter screen 7, an inner ring 13, and a connecting mechanism 8. The connecting ring 2 is located on the top of the housing 1, and its outer wall has a thread 3. One side of the housing 1 is fixedly connected to a handle 4. A first sealing ring 5 is fixedly connected to the top of the connecting ring 2. A second sealing ring 6 is provided on the inner wall of the housing 1 and is fixedly connected to the inner wall of the housing 1. The filter screen 7 is connected to the housing 1 through the connecting mechanism 8, and the filter screen 7 extends into the housing 1. The top of the filter screen 7 abuts against the bottom of the second sealing ring 6. The connecting mechanism 8 has several components, each including a connecting block 9, a limiting block 10, a T-slot 11, and an I-shaped block 12. One end of the connecting block 9 is connected to the bottom of the filter screen 7, and the other end of the connecting block 9 contacts the bottom of the housing 1. One end of the limiting block 10 is connected to the bottom of the housing 1. The bottom connection is provided, with the other end of the limiting block 10 contacting the bottom of the connecting block 9. Both the limiting block 10 and the connecting block 9 are provided with T-slots 11. The two ends of the I-shaped block 12 extend into the T-slots 11 of the limiting block 10 and the connecting block 9, respectively. The inner ring 13 extends into the housing 1 and contacts the inner wall of the housing 1. The bottom of the inner ring 13 contacts the top of the second sealing ring 6. The top of the housing 1 is provided with a magnetic block 14. One end of the magnetic block 14 is fixedly connected to the top of the housing 1, and the other end of the magnetic block 14 attracts the inner ring 13.

[0015] Working principle: such as Figure 1 As shown, the user puts the ground coffee powder into the housing 1 and connects it to the coffee machine of the appropriate model through the connecting ring 2 at the top of the housing 1. The thread 3 on the outer wall of the connecting ring 2 is precisely matched with the thread of the coffee machine interface. Its size can be designed according to actual needs and is not limited here. The staff can hold the handle 4 with the anti-slip silicone layer and rotate the housing 1 to more easily complete the sealing connection with the coffee machine. After docking, place the cup under the filter screen 7, turn on the coffee machine, pour hot water into the housing 1 and mix it thoroughly with the coffee powder. The mixed coffee liquid is then filtered through the filter screen 7 and flows into the cup (the filter screen 7 can intercept coffee powder residue to ensure the purity of the liquid). The brewing process is now complete. This structure comes with three mesh sizes (0.3mm, 0.8mm, and 1.2mm), labeled "Suitable for fine powder," "medium-coarse powder," and "coarse powder," respectively. The model number is laser-engraved on the edge of the filter screen for easy matching by the user. After finishing the work, hold handle 4 and rotate housing 1 in the opposite direction to separate it from the coffee machine. Pour out the coffee powder remaining in housing 1, and then disassemble inner ring 13: pull inner ring 13 forcefully to overcome the attraction of magnetic block 14 and separate it from housing 1. Since the bottom of inner ring 13 is tightly abutted against the second sealing ring 6 to achieve a seal, and the top is higher than the edge of housing 1, it can prevent coffee powder from leaking out and does not affect the connection with the coffee machine. At the same time, the inner wall of housing 1 does not come into direct contact with coffee powder due to the isolation of inner ring 13. Therefore, only inner ring 13 needs to be cleaned separately. The disassembly design greatly simplifies the cleaning process. Next, disassemble the filter screen 7: Pull the I-shaped block 12 forcefully (its outer rubber layer makes it form a damping fit with the T-slot 11, and it will not loosen during normal use), overcome the friction and pull it out from the T-slot 11 of the limiting block 10 and the connecting block 9; then rotate the filter screen 7 to drive the connecting block 9 to separate from the limiting block 10 (the sufficient space reserved between the two ensures smooth rotation), and the filter screen 7 can be removed. The disassembled filter screen 7 can be placed in an external ultrasonic cleaning device for thorough cleaning to avoid cleaning dead corners caused by the fixed connection; at the same time, rinse the inside of the housing 1 and the second sealing ring 6 with clean water. After cleaning or replacing (if filter 7 is damaged), reset each component by following the reverse steps described above. Those skilled in the art can complete the assembly according to the disassembly logic. The new filter 7 can be purchased from the manufacturer, and its mesh size is available in various models. The appropriate specification can be selected according to the requirements. In addition, the first sealing ring 5 at the top of the connecting ring 2 can ensure the seal when docking with the coffee machine to prevent water leakage. The inner ring 13 is made of food-grade martensitic stainless steel, which has good magnetic conductivity to facilitate stable adsorption with the magnetic block 14, and meets food contact safety standards. It is also rust-resistant and easy to clean. In this structure, the magnetic block 14 uses high-performance neodymium iron boron permanent magnet material and is processed by a precision magnetization process. Its initial adsorption force is set to 6-8N (actually tested to be able to stably withstand the weight of the inner ring 13 and 1.5 times the impact force generated by the water flow during brewing). The outer layer of the magnetic block 14 is covered with a food-grade 304 stainless steel protective shell, which can effectively resist the corrosion of hot water steam and the wear of coffee powder, ensuring that the magnetic force attenuation rate is less than 5% in the working environment of -20℃ to 120℃ (the service life can reach more than 5000 cycles). At the same time, the magnetic block 14 is fixed to the shell 1 by welding to avoid the loss of attraction force transmission due to loosening. Combined with the magnetic conductivity of the inner ring 13 (food-grade martensitic stainless steel), it can always maintain a stable adsorption state. The inner ring 13 will not fall off due to insufficient attraction force, nor will the disassembly convenience be affected by excessive attraction force, which fully meets the needs of long-term use.

[0016] To further improve the structural stability and force balance of the connection between the filter screen 7 and the housing 1, and to ensure that the filter screen 7 will not shift due to water flow impact or operational shaking during the brewing process, in this embodiment, several connecting mechanisms 8 are symmetrically distributed along the bottom of the housing 1. This symmetrical layout allows the fixing force on the filter screen 7 to be evenly distributed at all edges, avoiding loosening of the connection block 9 and the limiting block 10 due to excessive force on one side, or jamming of the I-shaped block 12 in the T-slot 11. At the same time, the symmetrically arranged connecting mechanisms 8 can ensure the force balance of the filter screen 7 during disassembly and installation, reduce wear caused by component tilting, extend service life, and work in conjunction with the anti-clogging design of the overall structure to improve the reliability of equipment operation.

[0017] To enhance the anti-slip effect during operation and ensure stable force application when the operator holds the handle 4 and rotates the housing 1 (especially when hands are wet or contaminated with coffee powder), in this embodiment, the outer wall of the handle 4 is fixedly wrapped with a layer of silicone. This silicone layer is made of highly elastic food-grade silicone material, which not only has a soft touch to improve grip comfort, but also has several longitudinal anti-slip grooves evenly distributed on its outer wall. The depth of the anti-slip grooves is designed to be 0.5-1mm, which can prevent slipping by increasing the friction between the hand and the handle 4, and will not make it difficult to clean coffee powder residue due to excessive groove depth. This design allows the operator to hold the handle 4 firmly when connecting to the coffee machine or disassembling parts, even if the hands are wet or powdery, reducing operational errors and matching the convenience and safety design of the overall structure.

[0018] To further improve the stability of the connection between the inner ring 13 and the housing 1, and to prevent the inner ring 13 from shifting or loosening due to external impact during brewing or disassembly, in this embodiment, two magnetic blocks 14 are provided and symmetrically distributed along the top of the housing 1. The two magnetic blocks 14 correspond to the two side edges of the inner ring 13 respectively. Through symmetrical adsorption force, the inner ring 13 is firmly fixed to the inner wall of the housing 1, so that the bottom of the inner ring 13 and the second sealing ring 6 always keep in close contact, ensuring a stable and reliable sealing effect. At the same time, the symmetrical arrangement of the magnetic blocks 14 can make the inner ring 13 bear force evenly, avoiding the inner ring 13 from tilting due to excessive adsorption force on one side. This not only prevents coffee powder from leaking out, but also ensures the structural consistency when docking with the coffee machine. This is consistent with the overall anti-clogging and easy-to-clean design logic, further improving the stability of the equipment operation.

[0019] To ensure the stability of the connection mechanism 8 in fixing the filter screen 7 and to prevent loosening or shaking during rinsing or disassembly, in this embodiment, the I-shaped block 12 and the T-shaped groove 11 are precisely matched. The size and shape of the I-shaped block 12 are perfectly adapted to the T-shaped groove 11 on the limiting block 10 and the connecting block 9. This ensures that the I-shaped block 12 can be smoothly embedded into the groove for connection, and the tight fit eliminates gaps, preventing the filter screen 7 from shifting under force (such as water flow impact or manual operation). At the same time, this matching design, together with the rubber layer on the outer wall of the I-shaped block 12, can maintain a moderate damping effect while ensuring a stable connection. This prevents accidental detachment during normal use and facilitates disassembly and cleaning. Together with the symmetrical distribution design of the connection mechanism 8, it further improves the overall stability of the connection between the filter screen 7 and the housing 1, ensuring long-term reliable operation of the equipment.

[0020] To ensure the stability of the connection between the handle 4 and the housing 1, and to prevent loosening or breakage when rotating the housing 1 to connect to the coffee machine or disassembling it, in this embodiment, the handle 4 and the outer wall of the housing 1 are integrally fixedly connected (such as by welding or high-strength bolts). This fixed connection method can evenly transmit the force applied by the hand to the housing 1, ensuring that the two move synchronously during rotation, and avoiding force transmission loss or component deformation caused by connection gaps.

[0021] 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.
