[0018] Compared with the prior art, this disclosure has at least the following advantages:
[0019] The aforementioned buffer structure, with its buffer elastic element positioned between the mounting frame and the grinding frame, has its two ends fixedly connected to both the mounting frame and the grinding frame, thus confining the grinding frame within the main body of the grinder. This allows the grinding frame to move relative to the main body of the grinder during the grinding of harder coffee beans, thanks to the elastic deformation capability of the buffer elastic element. The buffer elastic element absorbs and disperses the energy generated during collisions or impacts between the coffee beans and the grinding frame and grinding components, thereby extending the duration of the impact load on the grinding frame and grinding components. This reduces the impact force between the coffee beans and the grinding frame and grinding components, lowering the likelihood of damage or even destruction to the grinding frame and grinding components, and significantly reducing the maintenance costs of the coffee grinder.

[0030] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0031] like Figures 1 to 6 As shown, in one embodiment, a buffer structure 100 is installed within the grinder body 200 of a coffee bean grinder 10. The buffer structure 100 includes a mounting frame 110, a grinding assembly 120, and a buffer elastic member 130. The mounting frame 110 is used to install and fix the grinder body 200. The grinding assembly 120 includes a grinding frame 121 and a grinding element 122. The buffer elastic member 130 is disposed between the mounting frame 110 and the grinding frame 121. Both ends of the buffer elastic member 130 are fixedly connected to the mounting frame 110 and the grinding frame 121, respectively, so as to confine the grinding frame 121 within the grinder body 200, so that the grinding element 122 can grind harder coffee beans. During the grinding operation, the grinding rack 121 can move relative to the main body 200 of the grinder through the elastic deformation capability of the buffer elastic element 130. This allows the buffer elastic element 130 to absorb and disperse the energy generated during the collision or impact between the coffee beans and the grinding rack 121 and the grinding element 122. This extends the duration of the impact load on the grinding rack 121 and the grinding element 122, thereby reducing the impact force between the coffee beans and the grinding rack 121 and the grinding element 122. This reduces the possibility of damage or even destruction to the grinding rack 121 and the grinding element 122, and greatly reduces the maintenance cost of the coffee bean grinder 10.
[0032] like Figures 1 to 6 As shown, the first end of the grinding component 122 is rotatably connected to the mounting frame 110, and the second end of the grinding component 122 is disposed inside the grinding frame 121. The outer peripheral wall of the second end of the grinding component 122 is disposed opposite to the inner peripheral wall of the grinding frame 121 to form a grinding zone 123, so that when the grinding component 122 rotates relative to the main body of the grinder 200, the grinding assembly 120 can grind the coffee beans in the grinding zone 123.
[0033] In this embodiment, when the grinding assembly 120 grinds hard coffee beans, the coffee beans simultaneously apply a pressure impact load to the second end of the grinding rack 121 and the grinding element 122. The grinding rack 121 can move relative to the main body 200 of the grinder through the elastic deformation capability of the buffer elastic element 130, so that the buffer elastic element 130 can absorb and disperse the energy generated by the coffee beans and the grinding rack 121 and the grinding element 122 during the collision or impact, thereby extending the impact load time between the grinding rack 121 and the grinding element 122, so as to reduce the impact force between the coffee beans and the grinding rack 121 and the grinding element 122.
[0034] The aforementioned buffer structure 100, with the buffer elastic element 130 disposed between the mounting frame 110 and the grinding frame 121, has its two ends fixedly connected to the mounting frame 110 and the grinding frame 121 respectively, thereby confining the grinding frame 121 within the grinder body 200. This allows the grinding frame 121 to move relative to the grinder body 200 when the grinding unit 122 is grinding harder coffee beans, thanks to the elastic deformation capability of the buffer elastic element 130. The elastic component 130 can absorb and disperse the energy generated during the collision or impact between coffee beans and the grinding rack 121 and grinding component 122 through its own elastic deformation capability. This extends the time that the impact load acts on the grinding rack 121 and grinding component 122, thereby reducing the impact force between the coffee beans and the grinding rack 121 and grinding component 122. This reduces the possibility of damage or even destruction to the grinding rack 121 and grinding component 122, and greatly reduces the maintenance cost of the coffee bean grinder 10.
[0035] like Figure 1 and Figure 5As shown, in one embodiment, the bottom of the grinding rack 121 is used to abut and limit the bottom wall of the grinder body 200. The inner peripheral wall of the grinding rack 121 forms an upper grinding part 1211, and the outer peripheral wall of the second end of the grinding member 122 forms a lower grinding part 1221. The upper grinding part 1211 and the lower grinding part 1221 are arranged opposite to each other to form a grinding zone 123 together, so that when the lower grinding part 1221 rotates relative to the upper grinding part 1211, the upper grinding part 1211 can cooperate with the lower grinding part 1221 to grind the coffee beans located in the grinding zone 123.
[0036] like Figures 1 to 2 As shown, in one embodiment, the mounting bracket 110 has a clearance hole 111, the first end of the grinding component 122 is disposed in the clearance hole 111, the first end of the grinding component 122 has a first annular support flange 1222, and the inner peripheral wall of the clearance hole 111 has a second annular support flange 1111 disposed opposite to the first annular support flange 1222, so that the grinding component 122 is rotatably limited to the mounting bracket 110, so that the grinding component 122 can drive the lower grinding part 1221 to rotate relative to the lower grinding part 1221, thereby enabling the upper grinding part 1211 to cooperate with the grinding part to grind the coffee beans in the grinder body 200.
[0037] like Figures 1 to 2 As shown, in one embodiment, the buffer structure 100 further includes an abutment bearing 140, which is disposed between the first annular support flange 1222 and the second annular support flange 1111. The fixed end of the abutment bearing 140 is fixedly connected to the top of the second annular support flange 1111, and the bottom of the first annular support flange 1222 abuts against the rotating end of the abutment bearing 140 to reduce the friction between the grinding component 122 and the mounting frame 110, so that the grinding component 122 rotates more smoothly relative to the mounting frame 110, thereby greatly improving the grinding efficiency of the coffee bean grinder 10.
[0038] like Figures 1 to 3 As shown, in one embodiment, the buffer structure 100 further includes a pressure elastic member 150. The pressure elastic member 150 is sleeved on the elastic member and disposed between the mounting frame 110 and the lower grinding part 1221. The two ends of the pressure elastic member 150 elastically abut against the bottom of the mounting frame 110 and the top of the lower grinding part 1221, respectively. The pressure elastic member 150 is used to elastically press the bottom of the first annular support flange 1222 against the rotating end of the abutment bearing 140, so that the grinding part 122 can be limited to a preset position of the mounting frame 110 by the pressure elastic member 150, ensuring that the coffee bean grinder 10 can work stably and normally, and greatly improving the stability of the use of the coffee bean grinder 10.
[0039] like Figure 1 and Figure 3 As shown, in one embodiment, the buffer structure 100 further includes a first abutment 160 and a second abutment 170. The first abutment 160 is disposed between the bottom of the mounting bracket 110 and the first end of the pressure elastic member 150. The first side of the first abutment 160 is fixedly connected to the first end of the pressure elastic member 150, and the second side of the first abutment 160 abuts against the bottom of the mounting bracket 110. The second abutment 170 is disposed between the second end of the pressure elastic member 150 and the top of the lower grinding section 1221. The first side of the second abutment 170 is fixedly connected to the second end of the pressure elastic member 150, and the second side of the second abutment 170 abuts against the top of the lower grinding part 1221, so that the pressure elastic member 150 can increase its contact area with the mounting frame 110 and the lower grinding part 1221 through the first abutment 160 and the second abutment 170, so that the buffer elastic member 130 can evenly transmit the elastic force to the mounting frame 110 and the grinding part 122, thereby ensuring that the coffee bean grinder 10 has good operational stability.
[0040] like Figures 1 to 5 As shown, in one embodiment, a movable cavity 112 is formed between the mounting frame 110 and the grinding frame 121. A buffer elastic member 130 is located in the movable cavity 112. The buffer elastic member 130 is sleeved on the outer peripheral wall of the grinding frame 121, and both ends of the buffer elastic member 130 are fixed to the mounting frame 110 and the grinding frame 121 respectively, so that the grinding frame 121 can move relative to the mounting frame 110, so that the grinding frame 121 can reduce the impact force between the coffee beans and the grinding frame 121 and the grinding element 122 through the buffer elastic member 130.
[0041] like Figures 1 to 5 As shown, in one embodiment, the mounting bracket 110 is sleeved on the grinding frame 121 and slidably connected to the grinding frame 121 so that the grinding frame 121 can move relative to the mounting bracket 110.
[0042] like Figures 1 to 5 As shown, in one embodiment, the mounting bracket 110 and the grinding rack 121 are coaxially arranged to improve the structural compactness of the coffee bean grinder 10, and at the same time improve the operational stability of the coffee bean grinder 10.
[0043] like Figure 2 As shown, in this embodiment, the abutment bearing 140 is a thrust ball bearing to reduce the friction between the grinding component 122 and the mounting bracket 110.
[0044] like Figure 3 As shown, in this embodiment, the buffer elastic element 130 is a spring or elastic soft rubber, so that the buffer elastic element 130 can have good elastic deformation ability.
[0045] like Figure 3As shown, in this embodiment, the pressure elastic element 150 is a spring or elastic soft rubber, so that the pressure elastic element 150 can have good elastic deformation ability.
[0046] This disclosure also provides a coffee bean grinder 10, including a grinder body 200 and a buffer structure 100 as described in any of the above embodiments, with a mounting bracket 110 fixedly mounted on the grinder body 200.
[0047] like Figures 1 to 5 As shown, in one embodiment, the mill body 200 includes a bean hopper 210 and a knob ring 220. The inner peripheral wall of the first end of the knob ring 220 forms a first threaded abutment surface 221, and the outer peripheral wall of the bean hopper 210 forms a second threaded abutment surface 211. The first end of the knob ring 220 is sleeved on the bean hopper 210 and threadedly connected to it. The inner peripheral wall of the second end of the knob ring 220 forms a third annular support flange 222. The mill frame 121 is elastically pressed against the third annular support flange 222 by a buffer elastic element 130. The top of 2 is such that when the user rotates the knob ring 220 relative to the bean hopper 210 in a preset direction, the knob ring 220 can rise relative to the bean hopper 210, so that the third annular support flange 222 can drive the grinding rack 121 to move closer to or further away from the mounting frame 110 relative to the bean hopper 210, thereby increasing or decreasing the distance between the inner peripheral wall of the grinding rack 121 and the outer peripheral wall of the second end of the grinding component 122, so that the coffee bean grinder 10 can adjust the coarseness of the coffee powder, greatly improving the applicability of the coffee bean grinder.
[0048] like Figure 1 and Figure 5 As shown, in this embodiment, the coffee bean grinder 10 also includes a grinding drive 300. The fixed end of the grinding drive 300 is fixedly mounted on the grinder body 200. The grinder body 200 has a connecting hole 230. The driving end of the grinding drive 300 passes through the connecting hole 230 and is disposed in the clearance hole 111. The end of the first end of the grinding component 122 has a limiting hole 1223. The driving end of the grinding drive 300 is disposed in the limiting hole 1223 so that the first end of the grinding component 122 is limitedly connected to the driving end of the grinding drive 300. The grinding drive 300 is used to drive the grinding component 122 to rotate relative to the grinder body 200.
[0049] Compared with the prior art, this disclosure has at least the following advantages:
[0050] The aforementioned coffee bean grinder 10, with a buffer elastic element 130 disposed between the mounting frame 110 and the grinding frame 121, has its two ends fixedly connected to the mounting frame 110 and the grinding frame 121 respectively, thus confining the grinding frame 121 within the grinder body 200. This allows the grinding frame 121 to move relative to the grinder body 200 when the grinding element 122 is grinding harder coffee beans, thanks to the elastic deformation capability of the buffer elastic element 130. The elastic component 130 can absorb and disperse the energy generated during the collision or impact between coffee beans and the grinding rack 121 and grinding component 122 through its own elastic deformation capability. This extends the time that the impact load acts on the grinding rack 121 and grinding component 122, thereby reducing the impact force between the coffee beans and the grinding rack 121 and grinding component 122. This reduces the possibility of damage or even destruction to the grinding rack 121 and grinding component 122, and greatly reduces the maintenance cost of the coffee bean grinder 10.
[0051] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure.
