Description

Technical Field

[0001] This application relates to the field of coffee machine technology, and more particularly to a brewing device for a coffee machine. Background Technology

[0002] Most existing coffee machine brewing devices use a semi-detachable structure, meaning users can usually only remove the brewing cup and cannot remove the brewing head for deep cleaning. Because coffee grounds and residue easily remain inside the brewing head, these residues not only affect the taste of the coffee, but if the brewing head is not thoroughly cleaned over a long period, it can even lead to a decline in the coffee machine's performance and malfunctions. Utility Model Content

[0003] In view of the above-mentioned technical problems existing in the prior art, this application provides a brewing device for a coffee machine, which realizes quick disassembly and assembly of the brewing head assembly, and facilitates deep cleaning of the brewing head assembly after disassembly, thus solving the technical problems of inconvenient installation and removal and high cleaning difficulty of the existing brewing head assembly.

[0004] This application provides a brewing device for a coffee machine, comprising: The frame has a mounting slot with an open side. A brewing head assembly is slidably mounted on the frame via the opening of the mounting slot, and an abutment groove is formed on the upper part of the brewing head assembly. A locking assembly, mounted on the frame and positioned near the mounting slot, includes a trigger component and a lock cylinder structure slidably mounted on the frame. The lock cylinder structure has a locking position extending into the abutment slot and an unlocking position disengaged from the abutment slot. The trigger component acts on the lock cylinder structure under force, causing the lock cylinder structure to move towards the unlocking position. This structure enables quick assembly and disassembly of the brewing head assembly, facilitating deep cleaning after disassembly and solving the technical problems of inconvenient installation, removal, and cleaning of existing brewing head assemblies.

[0005] In some embodiments, the locking assembly further includes an action component acting on the lock cylinder structure, the action component being used to apply a force to the lock cylinder structure to extend it into the abutment groove. Thus, the action component can stably apply a force to the lock cylinder structure, enabling the lock cylinder structure to stably abut against the abutment groove, thereby improving the stability of the brewing head assembly mounted on the frame.

[0006] In some embodiments, the triggering component includes a button portion and a first elastic member. The button portion is used to push against the lock cylinder structure when force is applied, and the first elastic member is used to apply a force to the button portion to move it away from the lock cylinder structure. Thus, by applying force to the button portion, the user can switch the lock cylinder structure from the locked position to the unlocked position, thereby unlocking the entire brewing head assembly to the frame. The above structure is convenient to operate and has a simple structural design.

[0007] In some embodiments, the actuating component includes a second elastic member and a third elastic member, which are respectively disposed on opposite sides of the lock cylinder structure to cooperate in applying a force to the lock cylinder structure, causing it to extend into the abutment groove. Thus, by the cooperation of the second and third elastic members respectively disposed on opposite sides of the lock cylinder structure, the lock cylinder structure can stably abut against the abutment groove, thereby improving the stability of the brewing head assembly mounted on the frame.

[0008] In some embodiments, the frame is provided with a positioning groove, and the lock cylinder structure extends into the abutment groove via the positioning groove in the locked position. Thus, the positioning groove and the abutment groove cooperate to limit the position of the lock cylinder structure, ensuring the stability of the lock cylinder structure's locking of the brewing head assembly.

[0009] In some embodiments, the button portion has a first inclined surface on the side facing the lock cylinder structure, and the lock cylinder structure has a second inclined surface that abuts against the first inclined surface. The button portion acts on the second inclined surface through the first inclined surface, causing the lock cylinder structure to move towards the unlocked position. Thus, through the interaction between the first and second inclined surfaces, the button portion pushes against the lock cylinder structure, enabling the lock cylinder structure to move stably towards the unlocked position.

[0010] In some embodiments, the button portion has a guide rod, and the first elastic member is sleeved on the guide rod. The first elastic member applies a force to the button portion, causing it to move along the length direction of the guide rod. Thus, the first elastic member can be stably mounted via the guide rod, making the movement of the button portion more stable, avoiding unnecessary shaking or offset, and thereby ensuring the precise response of the button portion.

[0011] In some embodiments, the brewing head assembly includes a mounting bracket and a brewing head body mounted on the mounting bracket. The abutment groove is disposed on the mounting bracket, and the mounting bracket has first guide rails located on opposite sides of the brewing head body. The frame has second guide rails adapted to the first guide rails. Thus, the cooperation between the first and second guide rails improves the sliding stability of the brewing head body on the frame, reducing swaying or instability during movement.

[0012] In some embodiments, the mounting bracket is further provided with a handle for convenient operation of the brewing head assembly.

[0013] In some embodiments, the brewing head assembly further includes a first connector and a second connector communicating with the brewing head body. The first connector and the second connector are connected via a hose for discharging the brewing liquid formed after brewing. Thus, the discharging process of the brewing liquid becomes more stable and efficient through the cooperation between the first connector and the second connector.

[0014] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: This application slides the brewing head assembly onto the frame. After the brewing head assembly is pushed into place, the locking cylinder structure of the locking component extends into the abutment groove of the brewing head assembly to lock the brewing head assembly onto the frame. That is, the pushing process can complete the self-locking without the need for additional operation by the user. When disassembling, only the trigger component needs to be acted upon. The trigger component acts on the locking cylinder structure, causing the locking cylinder structure to move to the unlock position, thereby unlocking the brewing head assembly onto the frame. This achieves quick disassembly and assembly of the brewing head assembly, which is conducive to deep cleaning of the brewing head assembly after disassembly. It solves the technical problems of inconvenient installation and disassembly and high cleaning difficulty of existing brewing head assemblies. Attached Figure Description

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] This application provides a brewing device for a coffee machine. For example... Figures 1 to 7 As shown, the brewing device for a coffee machine includes a frame 1, a brewing head assembly 2, and a locking assembly. The frame 1 has a mounting slot 11 with an opening on one side. The brewing head assembly 2 is slidably mounted on the frame 1 through the opening of the mounting slot 11, and an abutment groove 21 is formed on the upper part of the brewing head assembly 2. The locking assembly is mounted on the frame 1 and located near the mounting slot 11. The locking assembly includes a triggering component 3 and a lock cylinder structure 4 slidably mounted on the frame 1. The lock cylinder structure 4 has a locking position that extends into the abutment groove 21 and an unlocking position that disengages from the abutment groove 21. The triggering component 3 acts on the lock cylinder structure 4 under force, causing the lock cylinder structure 4 to move to the unlocking position. Figure 6 and Figure 7 As shown, Figure 6 The lock cylinder structure 4 shown is in the unlocked position. Figure 7 The lock cylinder structure 4 shown is in the locked position.

[0020] When the brewing head assembly 2 slides into the mounting slot 11, it pushes against the locking cylinder structure 4, causing the locking cylinder structure 4 to move towards the unlocked position. After the brewing head assembly 2 is installed in place, the locking cylinder structure 4 will return to the locked position to stably fix the brewing head assembly 2 onto the frame 1. When the coffee machine performs coffee brewing, a certain brewing pressure is generated inside the brewing device. At this time, the locking cylinder structure 4 of the locking component extends into the abutment slot 21, which can stably lock the brewing head assembly 2 onto the frame 1. This can effectively resist the outward pushing force brought by the brewing pressure, avoid the risk of the brewing head assembly 2 becoming loose or popping out, and ensure the continuity and safety of the coffee brewing operation.

[0021] The aforementioned abutting groove 21 may have an abutting surface, and the lock cylinder structure 4 extends into the abutting groove 21, with the lower end of the lock cylinder structure 4 stably abutting against the abutting surface.

[0022] The aforementioned abutment groove 21 can be understood as a groove with an upper opening, and the lock cylinder structure 4 extends into the abutment groove 21 through the upper opening of the abutment groove 21.

[0023] The external force on the trigger component 3 can come from the user, that is, the user can manually operate the trigger component 3 to make the trigger component 3 act on the lock cylinder structure 4, thereby switching the lock cylinder structure 4 from the locked position to the unlocked position, thereby unlocking the brewing head assembly 2 as a whole to the frame 1.

[0024] This application achieves quick assembly and disassembly of the brewing head assembly 2 on the frame 1. After the brewing head assembly 2 is pushed into place, the locking cylinder structure 4 of the locking component extends into the abutment groove 21 of the brewing head assembly 2 to lock the brewing head assembly 2 onto the frame 1. That is, the pushing process can complete the self-locking without the need for additional operation by the user. When disassembling, only the trigger component 3 needs to be acted upon. The trigger component 3 acts on the locking cylinder structure 4, causing the locking cylinder structure 4 to move to the unlock position, thereby unlocking the brewing head assembly 2 onto the frame 1. This achieves quick assembly and disassembly of the brewing head assembly 2, which is conducive to deep cleaning of the brewing head assembly 2 after disassembly. It solves the technical problems of inconvenient installation and removal and high cleaning difficulty of the existing brewing head assembly 2.

[0025] In some embodiments, such as Figure 5 As shown, the locking assembly also includes an action component 5 that acts on the lock cylinder structure 4. The action component 5 is used to apply a force to the lock cylinder structure 4 to make it extend into the abutment groove 21.

[0026] Thus, the action component 5 can stably apply force to the lock cylinder structure 4, so that the lock cylinder structure 4 can stably abut against the abutment groove 21, thereby improving the stability of the brewing head assembly 2 installed on the frame 1.

[0027] The lock cylinder structure 4 may be provided with mounting parts on opposite sides. One end of the action component 5 abuts against the frame 1, and the other end acts on the lock cylinder structure 4 to stably apply force to the lock cylinder structure 4 via the action component 5.

[0028] The aforementioned action component 5 can be understood as applying an elastic force to the lock cylinder structure 4, so that the lock cylinder structure 4 can stably extend into the abutment groove 21 and abut against the inner wall of the abutment groove 21 when not being acted upon by the trigger component 3.

[0029] In some embodiments, such as Figures 5 to 7As shown, the trigger component 3 includes a button part 31 and a first elastic member 32. The button part 31 is used to push against the lock cylinder structure 4 when force is applied, and the first elastic member 32 is used to apply a force to the button part 31 to move it away from the lock cylinder structure 4.

[0030] Thus, by applying force to the button 31, the user can switch the lock cylinder structure 4 from the locked position to the unlocked position, thereby unlocking the brewing head assembly 2 entirely from the frame 1. The above structure is easy to operate and has a simple design.

[0031] The first elastic element 32 mentioned above can be a spring, a sheet, elastic rubber, silicone, etc. Any component that can undergo elastic deformation after being subjected to force is within the scope of this application, and this application does not make any specific limitations on it.

[0032] A friction portion may be formed on the side of the button portion 31 away from the first elastic member 32 to increase the tactile feedback and control when the user triggers the button portion 31. Through the friction portion, the user can obtain better tactile feedback when operating the button, making it easier to determine whether the button portion 31 has been triggered.

[0033] In some embodiments, such as Figure 5 As shown, the action component 5 includes a second elastic element 51 and a third elastic element 52. The second elastic element 51 and the third elastic element 52 are respectively disposed on opposite sides of the lock cylinder structure 4 to cooperate in applying a force to the lock cylinder structure 4 to extend it into the abutment groove 21.

[0034] Thus, by having the second elastic element 51 and the third elastic element 52 respectively located on opposite sides of the lock cylinder structure 4 cooperate to act on the lock cylinder structure 4, the lock cylinder structure 4 can stably abut against the abutment groove 21, thereby improving the stability of the brewing head assembly 2 installed on the frame 1.

[0035] The aforementioned second elastic element 51 and third elastic element 52 can be springs, sheet metal, elastic rubber, silicone, etc. Any component that can undergo elastic deformation after being subjected to force is within the scope of this application, and this application does not make specific limitations on it.

[0036] The aforementioned mounting portion can be constructed as a protruding post, that is, protruding posts are provided on both opposite sides of the lock cylinder structure 4, and the second elastic member 51 and the third elastic member 52 are respectively sleeved on the corresponding protruding posts to act on the lock cylinder structure 4.

[0037] In some embodiments, such as Figures 6 to 8 As shown, the frame 1 is provided with a positioning groove 12, and the lock cylinder structure 4 extends into the abutment groove 21 through the positioning groove 12 when in the locked position.

[0038] In this way, the positioning groove 12 and the abutment groove 21 can be used to limit the lock cylinder structure 4, so as to ensure the stability of the lock cylinder structure 4 locking the bubble head assembly 2.

[0039] like Figure 6 and Figure 7 As shown, Figure 6 and Figure 7 The lock cylinder structure 4 shown is located within the positioning groove 12 in both the locked and unlocked positions to improve the installation stability between the lock cylinder structure 4 and the frame 1, that is, the lock cylinder structure 4 is always kept in the position of abutting against the frame 1.

[0040] In some embodiments, such as Figure 6 and Figure 7 As shown, the button part 31 has a first inclined surface on the side facing the lock cylinder structure 4, and the lock cylinder structure 4 has a second inclined surface that abuts against the first inclined surface. The button part 31 acts on the second inclined surface through the first inclined surface, causing the lock cylinder structure 4 to move towards the unlock position.

[0041] Thus, through the interaction between the first and second inclined surfaces, the button part 31 pushes against the lock cylinder structure 4, enabling the lock cylinder structure 4 to move stably to the unlock position.

[0042] The inclination direction of the first and second inclined surfaces is such that after the button part 31 acts on the lock cylinder structure 4, the lock cylinder structure 4 can move towards the unlock position along the inclination direction.

[0043] In some embodiments, such as Figures 5 to 7 As shown, the button part 31 has a guide rod 33, and a first elastic member 32 is sleeved on the guide rod 33. The first elastic member 32 is used to apply a force to the button part 31 to make it move along the length direction of the guide rod 33.

[0044] In this way, the first elastic element 32 can be stably installed via the guide rod 33, making the movement of the button part 31 more stable and avoiding unnecessary shaking or deviation, thereby ensuring the accurate response of the button part 31. That is, when the user presses the button part 31, the elastic force provided by the first elastic element 32 enables the button part 31 to move smoothly along the length direction of the guide rod 33, thereby realizing the correct operation of the button part 31.

[0045] After the first elastic element 32 is sleeved on the outside of the guide rod 33, one end of the first elastic element 32 abuts against the button part 31 and the other end abuts against the frame 1, so as to ensure that the first elastic element 32 can stably apply force to the button part 31.

[0046] In some embodiments, such as Figures 2 to 7 As shown, the brewing head assembly 2 includes a mounting frame 22 and a brewing head body 23 mounted on the mounting frame 22. An abutment groove 21 is provided on the mounting frame 22. The mounting frame 22 is provided with first guide rails 24 located on opposite sides of the brewing head body 23. The frame 1 is provided with second guide rails 13 adapted to the first guide rails 24.

[0047] In this way, the cooperation between the first guide rail 24 and the second guide rail 13 can improve the sliding stability of the brewing head body 23 on the frame 1 and reduce swaying or instability during movement. This cooperation not only ensures the precise positioning of the brewing head body 23, but also effectively reduces friction and improves the smoothness and stability of sliding, allowing users to experience a smoother and more stable operation.

[0048] The second guide rail 13 includes a guide portion formed by the opposite side walls of the mounting groove 11 extending towards each other, the guide portion being used to support the first guide rail 24.

[0049] In some embodiments, such as Figure 4 As shown, the mounting bracket 22 is also equipped with a handle 25, which allows for convenient operation of the brewing head assembly 2, achieving a one-click quick-release effect of pushing in to lock, pressing to unlock, and holding to remove, thus reducing the user's operating threshold.

[0050] In some embodiments, such as Figure 6 and Figure 7 As shown, the brewing head assembly 2 also includes a first connector 26 and a second connector 27 that are connected to the brewing head body 23. The first connector 26 and the second connector 27 are connected by a hose for discharging the brewing liquid formed after brewing.

[0051] Thus, the discharging process of the brewing liquid becomes more stable and efficient through the cooperation between the first connector 26 and the second connector 27, and the design of the hose connection allows the brewing liquid to be discharged smoothly from the brewing device, avoiding liquid overflow or blockage.

[0052] The axis of the drain hole of the first connector 26 can be perpendicular to the axis of the drain hole of the second connector 27.

[0053] The following describes the operation of the brewing device for the coffee machine: In the initial state, the locking cylinder structure 4 is in the locked position. When the brewing head assembly 2 is pushed into place along the mounting slot 11 of the frame 1, the locking cylinder structure 4 automatically inserts into the abutment slot 21 under the elastic force of the action component 5, thereby completing the self-locking fixation between the brewing head assembly 2 and the frame 1. This ensures that the brewing head assembly 2 can be stably locked on the frame 1 during coffee brewing and will not pop out due to the pressure generated during brewing. When it is necessary to remove the brewing head assembly 2 from the coffee machine for cleaning or maintenance, press the button 31 of the trigger component 3. The locked state between the locking cylinder structure 4 and the brewing head assembly 2 is released, completing the unlocking. At this time, the brewing head assembly 2 can be easily removed from the mounting slot 11 of the frame 1 through the handle 25.

[0054] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of this utility model.
