[0002] In the field of coffee machine technology, commercial coffee machines are used very frequently, which means that the filter of the brewing head needs to be replaced frequently to maintain the quality and taste of the coffee. However, in the traditional coffee machine design, the filter replacement process is particularly cumbersome and inefficient. In particular, users often need to use special tools to pry out the filter laboriously. This process is not only time-consuming, but also very likely to damage the filter and the surrounding coffee machine structure, increasing the complexity and cost of maintenance.

[0003] For commercial environments, every filter replacement directly affects the operational efficiency of the cafe or restaurant. The design of the filter of the traditional coffee machine brewing head lacks modular thinking, and the filter is tightly coupled with the main structure of the coffee machine, making the disassembly and installation process complicated and time-consuming. Under high-frequency use, this design undoubtedly increases the difficulty of operation, affects work efficiency, and may even cause interruptions in coffee supply, thereby affecting customer experience and business profits. More importantly, due to the high-frequency use of commercial coffee machines, the problem of filter clogging or performance degradation is more prominent. However, due to the difficulty and fragility of traditional filter replacement, many operators often choose to postpone replacement, which not only affects the taste and quality of the coffee, but may also cause more serious damage to the coffee machine, thereby affecting business operations.

[0052] In the technical field of coffee machines, due to the high-frequency use of commercial coffee machines, the filter screen of the brewing head needs to be frequently replaced to ensure the coffee quality. However, the replacement process of the traditional design is both cumbersome and inefficient. It often requires using special tools to pry out the filter screen laboriously, which not only takes time, but also easily damages the filter screen and the surrounding structure of the coffee machine, increasing the maintenance cost. In a commercial environment, the filter screen replacement efficiency directly affects the operation benefit. The filter screen design of traditional coffee machines lacks the modular concept and is closely integrated with the main body structure, resulting in complex disassembly and installation. This design is obviously inappropriate in high-frequency use scenarios, increasing the operation difficulty and even possibly causing supply interruptions, damaging the customer experience and commercial interests. Especially the problems of filter screen blockage or performance decline are more prominent in commercial coffee machines. The difficulties and damage risks of the traditional replacement method often make the operators choose to delay the replacement, which not only sacrifices the coffee taste, but also may cause deeper damage to the coffee machine

[0053] To solve the above problems, please refer to Figures 1 to 9 , the embodiment of the present utility model provides a modular quick-change filter screen coffee machine, including:

[0054] Machine body 10, provided with a discharge port

[0055] Brewing head 20, installed at the discharge port and serving as the core component for coffee extraction. By precisely controlling the contact between the water flow and the coffee powder, coffee brewing and extraction are achieved

[0056] The coffee guide head 30 is detachably installed on the brewing head 20, ensuring smooth and precise outflow after coffee making. At the same time, it is convenient for users to replace or clean according to needs, guaranteeing the taste and quality of coffee.

[0057] The quick-disassembly mechanism 40 is used for the disassembly and assembly of the coffee guide head 30 and the brewing head 20. The quick-disassembly mechanism 40 is arranged above the brewing head 20 and installed on the machine body 10. The quick-disassembly mechanism 40 is connected to the coffee guide head 30 through the movable push rod 49. The design of the movable push rod 49 realizes the stable connection or rapid separation of the coffee guide head 30, enhancing the user experience. The quick installation and disassembly of the coffee guide head 30 can be achieved through simple operations, greatly saving the replacement time and reducing the operation difficulty. The movable push rod 49 is arranged on both sides of the brewing head 20, and the layout design on both sides ensures the stability of the movable push rod 49 during operation.

[0058] The filter screen module 50 is arranged between the brewing head 20 and the coffee guide head 30. As a key component for intercepting coffee grounds during the coffee extraction process, it ensures the outflow of pure coffee liquid. There are two filter screen modules 50, which are respectively rotatably installed on two movable push rods 49 through the adjustment connecting piece 60. The rotation directions of the two filter screen modules 50 are opposite. Here, it should be noted that the design of the double filter screen module 50 and the opposite rotation directions aims to ensure that the filter screen module 50 can be switched smoothly and quickly, improving the flexibility and efficiency of the filter screen module 50 switching, guaranteeing the continuity of the coffee machine operation. The modular design is easy for replacement, cleaning, and later maintenance. There are also accommodation bins 70 for accommodating the filter screen modules 50 on both sides of the machine body 10, used to hold the replaced filter screen modules 50. Specifically, the filter screen module 50 rotatably installed on the left movable push rod 49 rotates counterclockwise into the accommodation bin 70 on the left side of the machine body 10, while the filter screen module 50 rotatably installed on the right movable push rod 49 rotates clockwise into the accommodation bin 70 on the right side of the machine body 10, and the two do not interfere with each other. The brewing head 20 is located between the two accommodation bins 70. Such a layout design forms a compact and efficient working system among the brewing head 20, the filter screen module 50, and the coffee guide head 30, improving the switching speed of the filter screen module 50 and making the overall structure of the coffee machine appear compact and stable.

[0059] In this embodiment, the filter screen module 50 includes:

[0060] The filter screen main body 51, as the core filtering element, efficiently intercepts coffee grounds to ensure that the coffee liquid is pure and free of impurities.

[0061] The quick-installation ring frame 52. The filter screen main body 51 is detachably installed on the quick-installation ring frame 52 through the fixed ring frame 53, facilitating users to easily replace the filter screen main body 51 and improving the convenience of cleaning and maintenance.

[0062] The guiding member 54 is fixedly arranged on one side of the quick - installation ring frame 52 close to the movable push rod 49 and is adjustably installed on the adjusting connecting member 60, which ensures the stability of the installation of the filter screen module 50, realizes the flexible adjustment of the position degree of the filter screen module 50, and ensures the convenience of disassembling the filter screen module 50.

[0063] The adjusting connecting member 60 includes:

[0064] The connecting block 61 is installed on the movable push rod 49 through the rotating bearing sleeve 80. A first guiding groove 611 adapted to the guiding member 54 is formed on the connecting block 61. On both symmetric sides of the bottom of the first guiding groove 611, guiding installation columns 612 are convexly provided. A first installation through - hole 546 corresponding to the guiding installation column 612 is formed on the guiding member 54, which enhances the stability and reliability of the connection.

[0065] The elastic member 62 is arranged on the upper and lower sides of the guiding member 54 and is sleeved on the guiding installation column 612. One end of the elastic member 62 arranged on the lower side of the guiding member 54 abuts against the bottom of the first guiding groove 611.

[0066] The limiting plate 63 is installed on the side of the connecting block 61 where the first guiding groove 611 is formed. One end of the elastic member 62 arranged on the upper side of the guiding member 54 abuts against the limiting plate 63. The limiting plate 63 is used to limit the adjustment stroke of the guiding member 54 to ensure the stability of the structure. A first avoiding through - hole 631 corresponding to the rotating bearing sleeve 80 is also formed on the limiting plate 63, which provides necessary space for the rotating bearing sleeve 80 and ensures the compactness and functionality of the overall structure.

[0067] It should be noted that the design of the elastic member 62 effectively buffers the impact force during the disassembly and assembly process, protects the components from being damaged by instantaneous force, and at the same time ensures the smoothness and stability of the filter screen module 50 during the adjustment process. In particular, after the material guiding head 30 is disassembled and separated from the brewing head 20, it also provides an adjustable disassembly clearance space for further separating the filter screen module 50 from the material guiding head 30. That is, by lifting the guiding member 54, the elastic member 62 arranged on the upper side of the guiding member 54 is compressed, and the elastic member 62 arranged on the lower side of the guiding member 54 is stretched, thereby generating a separation gap. Then, by rotating the filter screen module 50, the separation of the filter screen module 50 from the material guiding head 30 can be realized, and the operation is simple.

[0068] The guide member 54 is also provided with a first guide through groove 541. This design ensures the precise path guidance of the filter screen module 50 during the disassembly process, enhancing the stability and accuracy of the operation. In the middle of both sides of the first guide through groove 541, there are convex first guide limit blocks 542. On the connecting block 61, there is a second guide groove 613 corresponding to the first guide limit block 542. On the side of the first guide through groove 541 away from the elastic member 62, there is also a convex second guide limit block 543. On the connecting block 61, there is also a third guide groove 614 adapted to the second guide limit block 543. The design of the first guide limit block 542 and the second guide limit block 543 further ensures the stability of the limit and guidance, while avoiding large swings during the replacement of the filter screen module 50 and the deformation of the guide member 54 caused by concentrated stress, improving the mechanical properties of the overall structure. On the connecting block 61, there is also an installation screw hole 544, which is arranged on the side of the connecting block 61 away from the elastic member 62. The installation screw hole 544 passes through the second guide limit block 543 and communicates with the first guide through groove 541. A screwed tightening member 545 is installed on the installation screw hole 544. One end of the screwed tightening member 545 passes through the installation screw hole 544 and is in abutting connection with the bottom of the third guide groove 614. By rotating the screwed tightening member 545, the firm locking of the filter screen module 50 can be achieved, enhancing the reliability of the coffee machine during use. When separating the filter screen module 50 from the material guiding head 30, a stable locking force is provided, liberating the manual continuous lifting of the guide member 54, facilitating the switching and maintenance of the filter screen module 50. The rotating bearing sleeve 80 is arranged between the first guide groove 611 and the third guide groove 614 and is installed on the connecting block 61, making the structural layout more compact and optimizing the rotation mechanism of the filter screen module 50.

[0069] Furthermore, an annular convex block 511 is convexly provided on the outer peripheral side of the filter screen main body 51. An external thread 512 is provided on the outer peripheral side of the annular convex block 511. On the fixed ring frame 53, an annular groove 531 adapted to the annular convex block 511 is provided. An internal thread 532 corresponding to the external thread 512 is provided on the side of the annular groove 531 away from the center of the annular convex block 511. The filter screen main body 51 is screwed and installed on the fixed ring frame 53 to form a firm sealed connection, which not only ensures the convenient operation of disassembling and assembling the filter screen main body 51, but also effectively prevents the problem of coffee liquid leakage.

[0070] On one side of the quick - installation ring frame 52 close to the filter screen main body 51, there are multiple clamping parts 521. On the fixed ring frame 53, there are clamping holes 534 adapted to the clamping parts 521. The fixed ring frame 53 is detachably installed on the quick - installation ring frame 52 through the clamping parts 521. This design greatly simplifies the installation steps of the filter screen module 50. Through the quick docking of the clamping parts 521 and the fixed ring frame 53, the efficient installation of the filter screen main body 51 is realized. On the quick - installation ring frame 52, there are also multiple positioning convex columns 522. The positioning convex columns 522 are arranged between every two clamping parts 521. The clamping parts 521 and the positioning convex columns 522 are equally spaced along the circumferential direction of the quick - installation ring frame 52. On the fixed ring frame 53, there are multiple positioning through - holes 533 corresponding to the positioning convex columns 522. The design of the positioning convex columns 522 not only enhances the structural strength of the quick - installation ring frame 52 but also provides an additional positioning reference for the fixed ring frame 53, optimizing the installation efficiency and stability of the filter screen module 50 and enabling each installation to reach the best state.

[0071] The quick - disassembly mechanism 40 includes:

[0072] The installation support plate 41 is arranged above the brewing head 20 and firmly installed on the machine body 10, providing a solid support foundation for the entire quick - disassembly mechanism 40. On both sides of the installation support plate 41, there are second avoidance through - holes corresponding to the movable push rods 49, ensuring the smooth movement of the movable push rods 49 during movement and effectively avoiding interference between structures. There is also an installation convex block 42 between the two movable push rods 49, and the installation convex block 42 is fixedly installed on the installation support plate 41.

[0073] The pressing curved block 43 is rotatably installed on the connecting convex block. At one end of the pressing curved block 43 away from the installation convex block 42, there is also a first connecting rod member 44 rotatably installed. One end of each of the two movable push rods 49 close to the installation convex block 42 is connected to both ends of the first connecting rod member 44. This design realizes the linkage between the pressing curved block 43 and the movable push rods 49, converting the user's pressing action into the vertical movement of the movable push rods 49 and improving the transmission conversion efficiency of the mechanism. The first connecting rod member 44 and the movable push rods 49 are vertically arranged. At one end of the movable push rod 49 close to the material guiding head 30, there is a second connecting rod member 47 installed. The adjusting connecting member 60 is rotatably installed on the second connecting rod member 47. The design of the second connecting rod member 47 facilitates the quick assembly of the adjusting connecting member 60 and improves the assembly efficiency.

[0074] The operating rod 45 is installed on the pressing curved block 43 and is used to perform the pressing or lifting operation of the pressing curved block 43. It conforms to the ergonomic principle, facilitating the user to easily perform the operation, improving the switching efficiency of the filter screen module 50 while enhancing the user experience.

[0075] The quick-disassembly mechanism 40 further includes a bearing plate 46, which not only serves as a stable installation platform for the material guide head 30, but also bears the functions of partial force transmission and connection in the quick-disassembly mechanism 40. The material guide head 30 is fixedly installed in the middle of the bearing plate 46. Second installation through holes 461 are formed on both sides of the bearing plate 46. A screwing member 48 is provided on the second installation through hole 461.

[0076] Furthermore, a cleaning and drying component is provided in the accommodation bin 70, and the cleaning and drying component is used to clean and dry the replaced filter module 50.

[0077] Specifically, the cleaning and drying component precisely operates on the replaced filter module 50. First, through an efficient cleaning mechanism, using a suitable cleaning liquid and water flow, the coffee residues and oil stains on the filter module 50 are thoroughly removed to ensure the cleanliness and hygiene standards of the filter module 50. Immediately afterwards, the drying system built in the cleaning and drying component is quickly started, and the filter module 50 is comprehensively dried using hot air or warm air to effectively remove the residual moisture, prevent bacteria from breeding, and keep the filter module 50 dry and fresh. This integrated cleaning and drying design not only saves the time and effort of the user to manually clean the filter module 50, but also ensures that the filter module 50 can be restored to the best state before the next use, prepares for the next replacement of the filter module 50, not only extends the service life of the filter module 50, but also improves the overall performance and reliability of the coffee machine.

[0078] First avoidance through grooves 11 and second avoidance through grooves 12 are formed on one side of the two accommodation bins 70 close to the brewing head 20. The first avoidance through groove 11 and the second avoidance through groove 12 are arranged vertically. A third avoidance through groove 13 is also formed on the machine body 10. The two second avoidance through grooves 12 are communicated through the third avoidance through groove 13.

The second avoidance through groove 12 and the third avoidance through groove 13 are both used to enable the filter module 50 to smoothly transfer into the accommodation bin 70. The filter module 50 transferred into the accommodation bin 70 can move along the length direction of the first avoidance through groove 11 driven by the movable push rod 49.

[0079] Here, the design of the second avoidance through slot 12 and the third avoidance through slot 13 provides a direct and continuous channel for the filter screen module 50 from the area of the brewing head 20 to the area of the accommodation bin 70, effectively reducing the obstacles on the transfer path and further improving the replacement efficiency of the filter screen module 50. In addition, both the second avoidance through slot 12 and the third avoidance through slot 13 are designed at the same level. This detail treatment ensures the stability and accuracy of the filter screen module 50 during the transfer process, avoiding problems such as jamming or deviation caused by height differences. At the same time, both the first avoidance through slot 11 and the second avoidance through slot 12 are in communication with the inside of the accommodation bin 70, providing the necessary conditions for the smooth transfer of the filter screen module 50. In particular, when the installation of the brewing head 20 and the material guiding head 30 is completed after the replacement of the filter screen module 50, the movable push rod 49 is lifted, and at the same time, it drives the filter screen module 50 that has been replaced and transferred to the accommodation bin 70 to move along the length direction of the first avoidance through slot 11 towards the top of the accommodation bin 70.
