Description

Technical Field

[0001] The present application relates to the field of coffee machines, and in particular to a coffee machine with a movable brewing head. Background Art

[0002] The coffee machine precisely controls water temperature and pressure to quickly extract the essence of coffee and produce rich and mellow coffee drinks. It not only simplifies the coffee-making process, but also retains the original flavor and aroma of the coffee beans, allowing users to easily enjoy high-quality coffee time in their busy lives.

[0003] When a user uses a coffee machine to make coffee, he needs to put coffee beans and the like into the coffee machine and place the container on the placement table below the brewing head of the coffee machine. After the preparations are ready, the coffee machine is started and the brewing head begins to flow out coffee liquid, which is collected by the container. The operation is simple, and during the design process, a certain distance is set between the liquid outlet of the brewing head and the placement table to adapt to the placement requirements of containers of different heights. However, there is a problem: since there is a certain distance between the container and the brewing head, when the liquid outlet of the brewing head begins to flow into the container, liquid splashing is likely to occur, which has a certain impact on the user experience.

[0004] Therefore, in order to solve the above problem, there is a coffee machine with a lifting mechanism on the brewing head, which can rise or fall along the coffee machine by driving the brewing head through the motor gear structure. During use, the user only needs to adjust the height of the brewing head through the control panel, so that it can adapt to the liquid receiving requirements of containers of different heights, effectively solve the problem of coffee liquid splashing, and is conducive to popularization and application. However, the problem with this coffee machine is that: because it is an electric drive structure, the brewing head is in a linear motion state during the process of rising and falling along the coffee machine. When the user fails to release the control button in time during the process of adjusting the height of the brewing head, the brewing head will continue to rise or fall along the coffee machine, thereby causing the user to control the brewing head to rise and fall along the coffee machine for a second time through the control panel so that its stopping position meets the requirements. The operation is cumbersome and there is room for improvement. Utility Model Content

[0005] In order to facilitate the adjustment of the height of the brewing head, the present application provides a coffee machine with a movable brewing head.

[0006] The present application provides a coffee machine with a movable brewing head adopts the following technical solution:

[0007] A coffee machine with a movable brewing head comprises a coffee machine body, a brewing head, a mounting seat and a fixed seat, wherein the coffee machine body is used to make coffee liquid, the brewing head is arranged on the mounting seat, and the fixed seat is detachably arranged on the coffee machine body, the mounting seat is provided with a slide rail, the fixed seat is provided with a sliding surface, the slide rail and the sliding surface are slidably matched, and the slide rail is provided with a spring piece, and the spring piece is used to drive the slide rail to press against the sliding surface.

[0008] By adopting the above technical solution, the brewing head is arranged on the mounting seat, and the mounting seat is provided with a slide rail, and the slide rail slides with the sliding surface. At the same time, the fixed seat is provided on the coffee machine body, so that the brewing head can slide along the coffee machine body, thereby meeting the purpose of adjusting the height of the brewing head along the coffee machine body. At the same time, the elastic potential energy provided by the spring is used to drive the slide rail to press against the sliding surface, so that the brewing head can stay in the set position when it is not subjected to external force. Through the above process, the user can drive the slide rail to slide along the sliding surface by applying force to the brewing head. When the user cancels the force applied to the brewing head, the elastic potential energy provided by the spring is used to drive the slide rail to press against the sliding surface, thereby achieving the purpose of the brewing head staying in the set position, and the operation is simple.

[0009] Preferably, a limiting groove is provided on the slide rail, and a boss is provided in the middle area of ​​the spring piece along the length direction. The boss is located in the limiting groove, and the boss abuts against the coffee machine body.

[0010] By adopting the above technical solution, since the boss abuts against the coffee machine body, the coffee machine body applies a reaction force to the spring piece, so that the two ends of the spring piece along the length direction can drive the slide rail to abut against the sliding surface, so that the brewing head can stay stably in the set position when not subjected to external force. At the same time, the installation position of the spring piece along the slide rail is limited by the limit groove, reducing the probability of the spring piece loosening or falling off along the slide rail due to excessive elastic potential energy of the spring piece.

[0011] Preferably, a clamping portion and a pressing portion are respectively provided on the slide rails on both sides of the limiting groove. When the boss is located in the limiting groove, both ends of the spring sheet along the length direction are respectively in contact with the clamping portion and the pressing portion.

[0012] By adopting the above technical solution, through the cooperation of the pressing part and the clamping part, the purpose of limiting the installation position of the spring along the slide rail is achieved, the position offset of the spring along the slide rail is reduced, and the spring can be stably clamped on the slide rail.

[0013] Preferably, a mounting groove is provided on the slide rail located at the clamping portion.

[0014] By adopting the above technical solution, the spring clip can be easily installed on the slide rail through the installation groove, which improves the convenience of installing the spring clip on the slide rail and reduces the probability of the spring clip producing irreversible deformation due to excessive deformation during installation, thereby reducing the elastic potential energy of the spring clip.

[0015] Preferably, a sliding groove is provided on the fixing seat, and the groove width of the sliding groove and the width tolerance of the mounting seat are clearance fit. When the slide rail slides along the sliding surface, the mounting seat slides along the sliding groove following the slide rail.

[0016] By adopting the above technical solution, the sliding path of the mounting seat along the coffee machine body is limited by the sliding groove, which reduces the deflection of the mounting seat when sliding along the coffee machine body, so that the brewing head can slide smoothly along the coffee machine body.

[0017] Preferably, a mounting position is provided on the coffee machine body, the contour of the mounting position is adapted to the shape of the fixing seat, and the fixing seat is provided on the mounting position.

[0018] By adopting the above technical solution, the position of the fixing seat when installed on the coffee machine body is limited by the installation position, which improves the convenience of installing the fixing seat on the coffee machine body and also makes it easier for users to disassemble and assemble the fixing seat along the coffee machine body.

[0019] Preferably, a reinforcing rib is provided at the connection between the slide rail and the mounting seat.

[0020] By adopting the above technical solution, the reinforcing ribs are helpful to improve the rigidity of the connection between the slide rail and the mounting seat, and reduce the probability of the slide rail being deformed or broken along the mounting seat due to excessive force applied by the spring clip on the slide rail.

[0021] Preferably, wear-resistant parts are provided on the sliding surface.

[0022] By adopting the above technical solution, when the user adjusts the height of the brewing head, the slide rail needs to slide along the sliding surface. The wear-resistant parts are helpful in reducing the sliding friction between the slide rail and the sliding surface during sliding, thereby slowing down the wear rate of the slide rail and / or the sliding surface, and playing a positive guiding role in improving the service life of the slide rail and / or the sliding surface.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The cooperation between the slide rail and the sliding surface allows the brewing head to slide along the coffee machine body. At the same time, the elastic potential energy provided by the spring clip allows the user to apply force to the brewing head to drive the slide rail to slide along the sliding surface. When the user releases the force on the brewing head, the elastic potential energy provided by the spring clip drives the slide rail to abut the sliding surface, so that the brewing head can stay in the set position, which is easy to operate.

[0025] 2. Because the boss abuts against the coffee machine body, the coffee machine body applies a reaction force to the spring, so that the ends of the spring along the length direction can drive the slide rail to abut against the sliding surface, so that the brewing head can stay stably in the set position when no external force is applied;

[0026] 3. Through the cooperation of the pressing part and the clamping part, the purpose of limiting the installation position of the spring along the slide rail is achieved, reducing the position offset of the spring along the slide rail, so that the spring can be stably clamped on the slide rail.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a coffee machine with a movable brewing head 2. Figures 1 to 3A coffee machine with a movable brewing head 2 includes a coffee machine body 1, a brewing head 2, a mounting base 3 and a fixed base 4. The coffee machine body 1 is used to make coffee liquid. The brewing head 2 is arranged on the mounting base 3. The fixed base 4 is detachably arranged on the coffee machine body 1. A slide rail 31 is provided on the mounting base 3, and a sliding surface 41 is provided on the fixed base 4. The slide rail 31 slides with the sliding surface 41. A spring piece 5 is provided on the slide rail 31, and the spring piece 5 is used to drive the slide rail 31 to abut against the sliding surface 41.

[0034] Specifically, the fixing base 4 is provided with a sliding groove 42. The width of the sliding groove 42 is clearance-matched with the width tolerance of the mounting base 3. When the slide rail 31 slides along the sliding surface 41, the mounting base 3 slides along the sliding groove 42 following the slide rail 31. The sliding groove 42 is formed through the mounting base 3 along the thickness direction. The sliding groove 42 defines the sliding path of the mounting base 3 along the coffee machine body 1, reducing the deflection of the mounting base 3 when sliding along the coffee machine body 1, thereby allowing the brewing head 2 to slide smoothly along the coffee machine body 1.

[0035] Furthermore, the coffee machine body 1 is provided with a mounting position 11, the contour of which matches the shape of the fixing base 4. The fixing base 4 is mounted on the mounting position 11. In this embodiment, the fixing base 4 can be fixed to the mounting position 11 by bolts, so as to facilitate the removal and installation of the fixing base 4 along the coffee machine body 1. The mounting position 11 is formed by a recess along the thickness of the coffee machine body 1. The mounting position 11 defines the position of the fixing base 4 when installed on the coffee machine body 1, thereby improving the convenience of installing the fixing base 4 on the coffee machine body 1 and facilitating the user's removal and installation of the fixing base 4 along the coffee machine body 1.

[0036] At the same time, a wear-resistant part 411 is provided on the sliding surface 41. The wear-resistant part 411 can be made of Teflon material or Saigang material. When the user adjusts the height of the brewing head 2, the slide rail 31 needs to slide along the sliding surface 41. The wear-resistant part 411 is helpful to reduce the sliding friction between the slide rail 31 and the sliding surface 41 during sliding, so as to slow down the wear rate of the slide rail 31 and / or the sliding surface 41, and play a positive guiding role in improving the service life of the slide rail 31 and / or the sliding surface 41.

[0037] The cam 31 is provided with a plurality of guide rails 31 on the bottom of the coffee machine body 1, and the guide rails 31 are provided with a plurality of guide rails 31 on the bottom of the coffee machine body 1. The guide rails 31 are provided with a plurality of guide rails 31 on the bottom of the coffee machine body 1, and the guide rails 31 are provided with a plurality of guide rails 31 on the bottom of the coffee machine body 1. The guide rails 31 are provided with a plurality of guide rails 31 on the bottom of the coffee machine body 1, and the guide rails 31 are provided with a plurality of guide rails 31 on the bottom of the coffee machine body 1.

[0038] Reference Figure 3 and Figure 4 A limiting groove 311 is provided on the slide rail 31 , and a boss 51 is provided in the middle area of ​​the spring piece 5 along the length direction. The boss 51 is located in the limiting groove 311 , and the boss 51 abuts against the coffee machine body 1 .

[0039] Specifically, the limiting groove 311 is formed by passing through the slide rail 31 along the thickness direction, and the boss 51 is formed by mechanical bending at the midpoint of the spring piece 5 along the length direction, and the width of the spring piece 5 is smaller than the groove width of the limiting groove 311, so that the boss 51 can be stuck in the limiting groove 311. When the boss 51 is stuck in the limiting groove 311, the boss 51 can abut against the surface of the mounting position 11. Because the spring piece 5 has the characteristic of recoverable elastic deformation, while the spring piece 5 applies a force to the surface of the mounting position 11, the mounting position 11 applies a reaction force to the spring piece 5 through the boss 51, driving the spring piece 5 to undergo elastic deformation, thereby achieving the purpose of the spring piece 5 driving the slide rail 31 to fit with the wear-resistant part 411 on the sliding surface 41.

[0040] At this time, the slide rail 31 is subjected to the force exerted by the spring piece 5, and the slide rail 31 fits with the wear-resistant part 411. When the user does not apply force to the brewing head 2, the mounting seat 3 can carry the brewing head 2 to stay stably at the current position along the coffee machine body 1; when the user applies force to the brewing head 2, the mounting seat 3 will carry the brewing head 2 and move along the coffee machine body 1 using the slide rail 31. During this process, the spring piece 5 always applies a force to the slide rail 31 to drive the slide rail 31 to move toward the wear-resistant part 411. When the force disappears, the slide rail 31 will stop moving along the wear-resistant part 411, thereby achieving the purpose of adjusting the height of the brewing head 2 along the coffee machine body 1.

[0041] At the same time, the limiting groove 311 limits the installation position of the spring piece 5 along the slide rail 31, thereby reducing the probability of the spring piece 5 being loose or popping out along the slide rail 31 due to excessive elastic potential energy of the spring piece 5.

[0042] Furthermore, the slide rail 31 is provided with a clamping portion 312 and abutting portion 313 on either side of the limiting groove 311. When the boss 51 is located within the limiting groove 311, the ends of the spring piece 5 along its length direction respectively abut against the clamping portion 312 and the abutting portion 313. The ends of the spring piece 5 along its length direction are mechanically bent to form a clamping platform 7. When the spring piece 5 is installed on the slide rail 31, the ends of the spring piece 5 along its length direction abut against the abutting portion 313 of the clamping portion 312 via the clamping platform 7.

[0043] Therefore, through the cooperation between the pressing portion 313 and the clamping portion 312, the purpose of limiting the installation position of the spring piece 5 along the slide rail 31 is achieved, reducing the position offset of the spring piece 5 along the slide rail 31, and allowing the spring piece 5 to be stably clamped on the slide rail 31.

[0044] Correspondingly, reinforcing ribs 6 are provided at the connection between the slide rail 31 and the mounting base 3. The number of reinforcing ribs 6 can be increased or decreased based on actual needs and the size of the mounting base 3. Since their functions are the same, their number is not specified here. The reinforcing ribs 6 help to increase the rigidity of the connection between the slide rail 31 and the mounting base 3, reducing the probability of the slide rail 31 deforming or breaking along the mounting base 3 due to excessive force exerted by the spring clip 5 on the slide rail 31.

[0045] Reference Figure 3 and Figure 4 A mounting groove 314 is provided on the slide rail 31 at the clamping portion 312. The mounting groove 314 is open at the end away from the slide rail 31 connected to the mounting seat 3. When the spring clip 5 needs to be installed, first, any end of the spring clip 5 along the length direction is clamped into the clamping portion 312 through the clamping platform 7. Because the width of the spring clip 5 is smaller than the width of the limiting groove 311, the position of the spring clip 5 along the slide rail 31 can be adjusted so that the boss 51 can be clamped into the limiting groove 311. Then, the end of the spring clip 5 away from the clamping portion 312 is pushed to move along the mounting groove 314 until the end of the spring clip 5 away from the clamping portion 312 is clamped into the abutting portion 313. At this time, the spring clip 5 can be stably installed on the slide rail 31 without the need for other mechanical components to fix the spring clip 5, which is easy to operate.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
