Description
Technical Field
[0001] This utility model belongs to the field of coffee machine technology, specifically relating to a coffee bean cup for a coffee machine. Background Technology
[0002] Coffee machines require coffee beans to be added for grinding during use. Typically, coffee beans are poured into the coffee bean container, which controls the amount of beans added by opening and closing. However, current coffee bean containers can only be opened and closed, and because they have lids, it's impossible to see if the bottom is open. Therefore, when disassembling the container assembly, it's common to forget to close the bottom, causing coffee beans to leak out. Furthermore, the inability to adjust the grind size while adding coffee beans is inconvenient. Therefore, to avoid these shortcomings, it is necessary to improve the existing technology. Utility Model Content
[0003] The purpose of this invention is to provide a coffee bean cup for a coffee machine that ensures the bean cup is closed and prevents coffee beans from leaking out when the bean cup assembly is disassembled.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0005] A coffee bean cup for a coffee machine includes a bean cup assembly. The assembly includes a bean cup portion, a chuck, an adjustment outlet cover, and a knob. The knob is connectable to the coffee machine's grinding adjustment system. The chuck is positioned above the knob and can be fixedly mounted on the coffee machine. A first latch is provided on the outer side of the adjustment outlet cover, and a first groove is provided on the inner side of the chuck to engage with the first latch. A connecting post is fixedly connected to the lower part of the bean cup portion, passing through the adjustment outlet cover and fixedly connected to the knob. In the process, the bottom of the bean cup is provided with a first coffee hole spaced apart along the circumferential direction, and the middle of the adjustment outlet cover is provided with a second coffee hole corresponding to the first coffee hole. The first coffee hole and the second coffee hole can switch between a staggered state and an aligned and connected state as the bean cup rotates. The outer periphery of the adjustment outlet cover is provided with an adjustment hole, and the end of the adjustment hole is provided with a limit baffle. The connecting post passes through the adjustment hole and is fixedly connected to the knob. When the first coffee hole and the second coffee hole are aligned and connected, the connecting post and the limit baffle are exactly abutted.
[0006] As a preferred embodiment of the coffee bean cup mentioned above, the outer periphery of the adjustment outlet cover is provided with an elastic hook, the hook of the elastic hook is downwardly protruding, the elastic hook can undergo elastic deformation under the action of external force, the knob is provided with an upwardly protruding first protrusion below the adjustment hole, the first protrusion is provided with a gentle slope on the clockwise side and a steep slope on the counterclockwise side, the first protrusion can push the hook of the elastic hook upward when passing through the elastic hook;
[0007] The force required for the gentle slope to lift the elastic hook is less than the locking force of the first buckle and the first slot in the clockwise direction, and the force required for the steep slope to lift the elastic hook is less than the locking force of the first buckle and the first slot in the counterclockwise direction.
[0008] As a preferred embodiment of the coffee bean cup described above, the chuck is provided with a second protrusion and a third protrusion, and the first slot is formed between the second protrusion and the third protrusion. The second protrusion is located on the clockwise side of the first latch, and the third protrusion is located on the counterclockwise side of the first latch. The second protrusion is provided with a guide slope at the end away from the first slot.
[0009] As a preferred embodiment of the coffee bean cup described above, the force required for the steep slope to lift the elastic hook is greater than the frictional force when the first buckle slides along the guide slope.
[0010] As a preferred embodiment of the coffee bean cup mentioned above, a safety stop is provided inside the bean cup to prevent coffee beans from clogging.
[0011] As a preferred embodiment of the coffee bean cup described above, the upper part of the bean cup is provided with a bean cup lid.
[0012] As a preferred embodiment of the aforementioned coffee bean cup, the inner side of the chuck is provided with a radially protruding limiting protrusion.
[0013] As a preferred embodiment of the aforementioned coffee bean cup, the outer side of the knob is provided with a screw-in part that screws into the grinding adjustment system of the coffee machine, and the screw-in part can counteract the adjustment switch of the grinding adjustment system of the coffee machine when rotated.
[0014] The coffee bean cup provided by this utility model has the following advantages compared with the prior art:
[0015] The knob of this invention can be connected to the grinding adjustment system of a coffee machine, allowing the grind to be adjusted to control the coarseness of the coffee powder. During knob rotation, the first and second coffee holes remain aligned and open. When disassembling the bean cup assembly, the first and second coffee holes are ensured to be closed in a staggered manner. By providing a gentle slope on the clockwise side and a steep slope on the counter-clockwise side of the first protrusion, the force required to open the elastic latch is small when rotating clockwise and large when rotating counter-clockwise, thus achieving a gentle slope. The force required to lift the elastic hook on the inclined surface is less than the locking force of the first buckle and the first slot in the clockwise direction. The force required to lift the elastic hook on the steep inclined surface is less than the locking force of the first buckle and the first slot in the counterclockwise direction. In this way, the locking force is different when unlocking is required at different positions through mechanical structure. This ensures that the first coffee hole and the second coffee hole are in the open state when rotating clockwise, and in the closed state when disassembling the bean cup assembly at the initial position by rotating counterclockwise. Moreover, the corresponding functions are achieved through mechanical structure, which has high reliability during operation, low manufacturing cost, and is suitable for mass production.

[0032] Please refer to the following: Figures 1 to 9 The coffee machine provided in the embodiments of this utility model will now be described.
[0033] like Figures 1 to 9 As shown, the present invention relates to a coffee bean cup for a coffee machine 100, comprising a bean cup assembly 200, which includes a bean cup portion 210, a chuck 240, an adjustment outlet cover 250, and a knob 260. The knob 260 can be connected to the grinding adjustment system of the coffee machine 100. The chuck 240 is disposed above the knob 260 and can be fixedly mounted on the coffee machine 100. The outer side of the adjustment outlet cover 250 is provided with a first latch 255, and the inner side of the chuck 240 is provided with a first groove 2 that cooperates with the first latch 255. 47. The first buckle 255 and the first slot 247 engage. A connecting post 212 is fixedly connected to the lower part of the bean cup 210. The connecting post 212 passes through the adjustment outlet cover 250 and is fixedly connected to the knob 260. The bottom of the bean cup 210 has first coffee holes 211 spaced apart along the circumferential direction. The middle part of the adjustment outlet cover 250 has a second coffee hole 251 corresponding to the first coffee holes 211. The first coffee holes 211 and the second coffee holes 251 can be staggered as the bean cup 210 rotates. Switching between aligned and connected states, the outer periphery of the adjusting outlet cover 250 is provided with an adjusting hole 254 and an elastic hook 252. A limit baffle 253 is provided at the end of the adjusting hole 254. The connecting post 212 passes through the adjusting hole 254 and is fixedly connected to the knob 260. The hook portion of the elastic hook 252 protrudes downwards and can elastically deform under external force. The knob 260 is provided with an upwardly protruding first protrusion 262 below the adjusting hole 254. A buffer is provided on one side of the first protrusion 262 in the clockwise direction. The slope 263 has a steep slope 264 on one side of the first protrusion 262 in the counterclockwise direction. The first protrusion 262 can push the hook of the elastic hook 252 upward when passing the elastic hook 252. The force required for the gentle slope 263 to push the elastic hook 252 is less than the locking force of the first buckle 255 and the first groove 247 in the clockwise direction. The force required for the steep slope 264 to push the elastic hook 252 is less than the locking force of the first buckle 255 and the first groove 247 in the counterclockwise direction.
[0034] In the initial state, the first coffee hole 211 and the second coffee hole 251 are in a staggered state, and the bean cup 210 is closed. When the bean cup 210 rotates clockwise, the first coffee hole 211 and the second coffee hole 251 switch to an aligned state, the bean cup 210 opens, and the coffee beans can fall into the coffee machine. During the rotation, when the gentle slope 263 of the first protrusion 262 passes the elastic hook 252, it can push up the elastic hook 252, causing the elastic hook 252 to undergo elastic deformation and pass smoothly. After passing, the elastic hook 252 returns to its original shape under the action of elastic force, and the connecting post 212 just touches the limit baffle 253. As the bean cup 210 continues to rotate clockwise, it causes the knob 260 to rotate in the grinding system of the coffee machine 100, adjusting the coarseness of the coffee powder. Since the connecting column 212 has already touched the limit baffle 253, the continued clockwise rotation will cause the adjustment outlet cover 250 to rotate, thereby disengaging the first latch 255 of the adjustment outlet cover 250 from the first slot 247 of the chuck. The adjustment outlet cover 250 can rotate until the first latch 255 touches the limit protrusion 243 of the chuck 240, at which point it is located at the maximum setting of the grinding system of the coffee machine 100.
[0035] When disassembling the bean cup assembly 200, the knob 260 needs to be turned counterclockwise, which requires rotating the bean cup part 210 counterclockwise. During the counterclockwise rotation of the bean cup, the steep slope 264 of the first protrusion 262 first encounters the elastic hook 252. Since the steep slope 264 is relatively steep, and the adjustment outlet cover 250 is still in a rotatable state when the steep slope 264 encounters the elastic hook 252, the steep slope 264 will push the elastic hook 252 instead of immediately lifting it up when the rotation continues. When the rotation reaches the guide slope 245 of the second protrusion 244, the first buckle 255 slides along the guide slope 245 into the first slot 247 and re-engages. At this point, continuing to rotate counterclockwise, since the force required for the steep slope 264 to lift the elastic hook 252 is less than the locking force of the first buckle 255 and the first slot 247 in the counterclockwise direction, continuing to rotate counterclockwise will not cause the first buckle 255 and the first slot 247 to disengage again. Instead, it will cause the steep slope 264 of the first protrusion 262 to lift the elastic hook 252 and pass smoothly through the elastic hook 252. The connecting post 212 moves along the adjustment hole 254 to the limiting baffle 253 at the end of the adjustment hole 254. At this time, the bean cup assembly 200 rotates to the initial position, and the first coffee hole 211 and the second coffee hole 251 have also rotated to the staggered initial state. The bean cup part 210 is closed, so when the bean cup assembly 200 is taken out, it can be ensured that the coffee beans will not leak out.
[0036] The first protrusion 262 is provided with a gentle slope 263 and a steep slope 264 in a clockwise direction. When rotating clockwise, the gentle slope 263 lifts the elastic hook 252, and when rotating counterclockwise, the steep slope 264 lifts the elastic hook 252. The shape and structure of the first protrusion 262 make the force required to lift the elastic hook 252 different when rotating clockwise and counterclockwise. Thus, the force required for the gentle slope 263 to lift the elastic hook 252 is less than the locking force of the first buckle 255 and the first slot 247 in the clockwise direction, and the force required for the steep slope 264 to lift the elastic hook 252 is less than the locking force of the first buckle 255 and the first slot 247 in the counterclockwise direction. In conjunction with adjusting the outlet cover 250, different functional effects are achieved when rotating clockwise and counterclockwise. When rotated clockwise, the gentle slope 263 can smoothly pass through the elastic hook 252 without affecting the engagement of the first latch 255 and the first slot 247. When rotated counterclockwise, the steep slope 264 can push the elastic hook 252 to rotate the adjusting outlet cover 250 counterclockwise, causing the first latch 255 and the first slot 247 to re-engage. Moreover, after re-engagement, continued counterclockwise rotation of the steep slope 264 can lift the elastic hook 252 to prevent the first latch 255 and the first slot 247 from disengaging again. The above functions are achieved through a mechanical structure, which has high reliability during operation, low manufacturing cost, and is suitable for mass production.
[0037] For example, the chuck 240 is provided with a second protrusion 244 and a third protrusion 246, and the first slot 247 is formed between the second protrusion 244 and the third protrusion 246. The second protrusion 244 is provided on the clockwise side of the first buckle 255, and the third protrusion 246 is provided on the counterclockwise side of the first buckle 255. The second protrusion 244 is provided with a guide slope 245 at the end away from the first slot 247. The force required for the gentle slope 263 to lift the elastic hook 252 is less than the clockwise locking force of the first buckle 255 and the first groove 247. The clockwise locking force of the first buckle 255 and the first groove 247, i.e. the locking force between the first buckle 255 and the second protrusion 244, mainly depends on the slope angle of the second protrusion 244 at the end near the first groove 247. The steeper the slope, the greater the locking force. Therefore, when the gentle slope 263 passes the elastic hook 252, it will lift the elastic hook 252 and allow it to pass smoothly without causing the first buckle 255 to disengage from the first groove 247 in the clockwise direction. The force required for the steep slope 264 to lift the elastic hook 252 is less than the locking force of the first buckle 255 and the first slot 247 in the counterclockwise direction. The locking force of the first buckle 255 and the first slot 247 in the counterclockwise direction, that is, the locking force between the first buckle 255 and the third protrusion 246, mainly depends on the slope angle of the third protrusion 246 at the end near the first slot 247. The steeper the slope, the greater the locking force. Therefore, after the first buckle 255 and the first slot 247 are re-engaged, the steep slope 264 will lift the elastic hook 252 and pass smoothly when it passes through the elastic hook 252, without causing the first buckle 255 to disengage from the first slot 247 in the counterclockwise direction.
[0038] For example, as a preferred embodiment of the above-described coffee machine, the force required for the steep ramp 264 to lift the elastic hook 252 is greater than the frictional force when the first latch 255 slides along the guide ramp 245. During the counter-clockwise rotation of the bean cup portion 210, when the first latch 255 rotates to the guide ramp 245 of the second protrusion 244, the first latch 255 slides along the guide ramp 245 and undergoes elastic deformation until it slides into the first slot 247 and returns to its original state to re-engage. The fact that the force required for the steep ramp 264 to lift the elastic hook 252 is greater than the frictional force when the first latch 255 slides along the guide ramp 245 ensures that during counter-clockwise rotation, the steep ramp 264 of the first protrusion 262 can push the elastic hook 252 to rotate the adjusting outlet cover 250, causing the first latch 255 to move along the guide ramp 245 and re-enter the first slot 247 to complete the engagement.
[0039] For example, the bean cup portion 210 is provided with a safety block 220 to prevent coffee beans from clogging. The safety block 220 is above the first coffee hole 211, blocking a portion of the coffee beans above the first coffee hole 211, preventing too many coffee beans from being squeezed together at the first coffee hole 211 and blocking it, thus preventing the coffee beans from falling smoothly.
[0040] For example, the inner side of the chuck 240 is provided with a radially protruding limiting protrusion 243. The limiting protrusion 243 limits the rotatable angle of the first latch 255, so that the adjustment outlet cover 250 can only be rotated until the first latch 255 touches the limiting protrusion 243 of the chuck 240.
[0041] For example, the outer surface of the knob 260 is provided with a screwing part 261 that screws into the grinding adjustment system of the coffee machine 100, and the screwing part 261 can abut against the adjustment switch of the grinding adjustment system of the coffee machine 100 when rotated. By rotating the knob 260, the screwing part 261 is driven to rotate, thereby driving the adjustment switch of the grinding adjustment system of the coffee machine 100 to adjust the grind size of the coffee powder.
[0042] The specific usage process of the coffee bean cup of this utility model is as follows:
[0043] Step 1: Adjust the bean cup 210 to the initial position, so that the first coffee hole 211 and the second coffee hole 251 are staggered. At this time, the first coffee hole 211 and the second coffee hole 251 are closed.
[0044] Step 2: After adding coffee beans to the bean cup 210, rotate the bean cup 210 clockwise. When the first damping sensation is encountered during the rotation, continue rotating. At this time, the gentle slope 263 of the first protrusion 262 passes through the elastic hook 252 and pushes up the elastic hook 252. When the damping sensation is encountered again, stop rotating. At this time, the connecting post 212 touches the limiting baffle 253, and the first coffee hole 211 and the second coffee hole 251 are aligned. The first coffee hole 211 and the second coffee hole 251 are fully open, and the coffee beans fall into the grinding system of the coffee machine 100.
[0045] Step 3: Continue to rotate the bean cup 210 clockwise to drive the knob 260 to adjust the grind size of the coffee powder. At this time, the connecting post 212 is blocked by the limiting baffle 253. Continue to rotate to drive the first buckle 255 to disengage from the first slot 247 in a clockwise direction. If you encounter resistance while rotating, you need to stop rotating, which means that the first buckle 255 has touched the limiting protrusion 243 and reached the limit of the grind setting of the coffee machine 100.
[0046] Step four: Rotate the bean cup 210 counterclockwise to drive the knob 260 back to its initial position. The first time resistance is encountered during the counterclockwise rotation indicates that the steep slope 264 has engaged the elastic hook 252. Continuing to rotate will cause the adjusting outlet cover 250 to rotate counterclockwise. The second time resistance is encountered indicates that the first latch 255 has re-engaged with the first slot 247. This is because the force required for the steep slope 264 to lift the elastic hook 252 is less than that required for the first latch 252. 5. The locking force of the first slot 247 in the counterclockwise direction is applied. At this time, the rotation continues to make the steep slope 264 push up the elastic hook 252. Then, the rotation continues until the third damping sensation is encountered and then stops, which means that the connecting post 212 has touched the limiting baffle 253 at the initial position. At this time, the knob 260 returns to the initial position, and the first coffee hole 211 and the second coffee hole 251 are also in the staggered initial closed state. Disassembling the bean cup assembly 200 will not cause the coffee beans in the bean cup part 210 to leak out.
[0047] The coffee bean cup provided by this utility model has the following advantages compared with the prior art:
[0048] The knob 260 of this invention can be connected to the grinding adjustment system of the coffee machine 100. The knob 260 drives the grinding system of the coffee machine 100 to adjust the coarseness of the ground coffee powder. During the rotation of the knob 260, the first coffee hole 211 and the second coffee hole 251 are kept aligned and open. When disassembling the bean cup assembly 200, the first coffee hole 211 and the second coffee hole 251 are kept in a staggered closed state. By providing a gentle slope 263 on the clockwise side and a steep slope 264 on the counterclockwise side of the first protrusion 262, the force required to open the elastic hook 252 when the first protrusion 262 rotates clockwise is small, and the force required to open the elastic hook 252 when rotating counterclockwise is large. The force required for the gentle slope 263 to lift the elastic hook 252 is less than the locking force of the first buckle 255 and the first slot 247 in the clockwise direction, and the force required for the steep slope 264 to lift the elastic hook 252 is less than the locking force of the first buckle 255 and the first slot 247 in the counterclockwise direction. In this way, the mechanical structure achieves different locking forces when unlocking is required at different positions, ensuring that the first coffee hole 211 and the second coffee hole 251 are in the open state when rotating clockwise, and the first coffee hole 211 and the second coffee hole 251 are in the closed state when rotating counterclockwise to the initial position to disassemble the bean cup assembly 200. Moreover, the corresponding functions are achieved through the mechanical structure, which has high reliability during operation, low manufacturing cost, and is suitable for mass production.
[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
