[0020] This utility model proposes a grinder 100 with a charging base, such as... Figure 1-4 As shown, the grinder 100 includes a housing 20, a grinding mechanism 10 disposed within the housing 20, and a power mechanism 50. The housing 20 has a material storage space 21. The power mechanism 50 and the grinding mechanism 10 are disposed at opposite ends of the material storage space 21. The power mechanism 50 is connected to the grinding mechanism 10 via a rotating shaft 60. The grinder 100 also includes a conduit connected to the housing 20 and disposed within the material storage space 21. A power supply component 30 is disposed at the end of the housing 20 away from the power mechanism 50. A wire is disposed inside the conduit, with one end of the wire electrically connected to the power mechanism 50 and the other end electrically connected to the power supply component 30.

[0021] Optionally, the power mechanism 50 includes a motor 51, a gearbox, a battery 53, and an inner shell 52. One end of the rotating shaft 60 is connected to the gearbox, and the rotating shaft 60 is connected to the output end of the gearbox. The output end of the gearbox has a transmission hole that matches the cross-sectional shape of one end of the rotating shaft 60, so the gearbox can transmit torque to the rotating shaft 60 through the transmission hole. The spring 62 and the motor 51 are connected to the input end of the gearbox. The motor 51 is used to provide torque and transmit torque to the gearbox, which then transmits the torque to the rotating shaft 60. In other embodiments, the motor 51 can also be directly connected to one end of the rotating shaft 60 to transmit torque without using a gearbox, which is not limited here. The power supply component 30 can be a charging plate 31 or an electrical connector for connecting to an external power source to charge the battery 53, ensuring that the grinder 100 can be used for a long time, which is not limited here. The power supply component 30 is arranged at the end of the shell 20 away from the power mechanism 50, that is, close to the grinding mechanism 10, so that the internal weight distribution of the grinder 100 is more reasonable and the rotation of the grinder 100 is more stable. Meanwhile, the connection between the power supply component 30 and the external power source is simpler and more convenient. The conduit can be a flexible hose or a rigid straight pipe, which connects to the housing 20. The wires used for electrically connecting the motor 51 and the power supply component 30 are all arranged inside the conduit. The wiring inside the grinder 100 is more standardized, and the wires will not interfere with other components during long-term use. The service life of the wires is longer, which improves the service life of the grinder 100.

[0022] In one embodiment, the grinder 100 also includes a fuse, with the spring 62 fuse disposed inside the spring 62 conduit.

[0023] Integrating the miniature tubular fuse into the existing wiring conduit eliminates the need for additional valuable internal space, aligning with the compact and highly integrated design trends in consumer electronics. All electrical connections and protective components are concealed within the conduit, preventing direct user access and resulting in a cleaner internal structure while also minimizing the risk of accidental contact. In the event of a short circuit or severe overload at motor 51, the fuse cuts off the fault current before it reaches downstream circuitry (such as the battery 53 protection board and motherboard chips). This effectively isolates the fault within the grinding chamber area, preventing escalation and protecting the more expensive and critical battery 53 and control unit.

[0024] In one embodiment, the wires are arranged in a loose spiral within the conduit. This arrangement allows for sufficient length slack in the wires, significantly reducing assembly difficulty. One end of the wire extends downwards from the conduit and connects to the positive and negative solder joints of the battery 53; the other end connects to the terminal of the motor 51 driving the grinding mechanism 10.

[0025] In one embodiment, the power supply unit 30 includes a charging plate 31 and a charging contact 32. The charging plate 31 is electrically connected to the battery 53 of the power mechanism 50, and one end of the charging contact 32 is electrically connected to the charging plate 31, while the other end of the charging contact 32 extends through the side of the housing 20. With this configuration, after prolonged use, the grinder 100 does not need to have the battery 53 removed from the housing 20; simply connecting the charging contact 32 to an external power source is sufficient to charge the battery 53, reducing disassembly and assembly costs and lowering the failure rate of the grinder 100.

[0026] In one embodiment, such as Figure 1-4 As shown, the grinder 100 also includes a charging base 40, which includes a recess 41 and a power supply contact 42. The power supply contact 42 is disposed on the side of the recess 41. The end of the housing 20 away from the power mechanism 50 of the spring 62 can be inserted into the recess 41, so that the power supply contact 42 is electrically connected to the charging contact 32. In this way, the charging board 31 is arranged at the end of the housing 20 away from the power mechanism 50 of the spring 62, making the connection between the charging board 31 and the charging base 40 simpler and reducing the wiring difficulty.

[0027] Specifically, the lower end of the grinder 100 is housed within the receiving cavity, such as... Figure 3 As shown, the sidewall of the receiving cavity is provided with anti-fooling protrusions, such as... Figure 4 As shown, the bottom of the housing 20 is provided with a foolproof groove, and the foolproof protrusion is adapted to the foolproof groove so that the power supply contact 42 and the charging contact 32 are in direct contact, ensuring contact charging between the grinder 100 and the charging base. It should be noted that the charging base 40 may have one recess 41 or multiple recesses. In this embodiment, the charging base 40 has two recesses 41 arranged side by side to charge two grinders 100 simultaneously, thereby improving charging efficiency.

[0028] In one embodiment, the power mechanism 50 includes an inner shell 52, a motor 51 mounted on the inner shell 52, and a battery 53. The inner shell 52 is connected to the housing 20. The output end of the motor 51 is connected to a rotating shaft 60 to drive the rotating shaft 60 to rotate. One end of a conduit is connected to the inner shell 52, and the wires inside the conduit are electrically connected to the battery 53. Optionally, the inner shell 52 includes a left shell and a right shell that interlock with each other. After the left and right shells are interlocked, they form an installation space for mounting the motor 51 and the battery 53. In this way, the entire power mechanism 50 can be assembled before being installed into the housing 20, reducing the installation difficulty of the grinder 100. Further, the left and right shells are fixed or snap-fitted to the housing 20, respectively, which is not limited here. Further, one end of the conduit extends into the installation space to facilitate the electrical connection between the battery 53 and the wires. The conduit can be integrally formed with the inner shell 52 or it can be separate from it, which is not limited here.

[0029] In one embodiment, the housing 20 further includes a support 64 and a spring 62. The support 64 is located at the end of the hopper space 21 away from the motor 51 and is connected to the lower end of the hopper. The grinding mechanism 10 includes a male grinding head 11 and a female grinding head 12. The male grinding head 11 is connected to the other end of the rotating shaft 60, and the female grinding head 12 is connected to the housing 20. The male grinding head 11 is located inside the female grinding head 12 and can rotate coaxially relative to the female grinding head 12, so that the material passing through the gap between the outer side of the male grinding head 11 and the inner side of the female grinding head 12 is ground. One end of the spring 62 abuts against the support 64, and the other end abuts against the male grinding head 11.

[0030] Optionally, the bracket 64 is connected to the housing 20. The bracket 64 has a rotating hole that matches the size and shape of the rotating shaft 60. The rotating shaft 60 passes through the rotating hole, the spring 62, the male mold head, and the bearing part. The end of the rotating shaft 60 is connected to the adjusting part. The inner side of the male mold head is used for grinding materials. The grinding head is connected to the rotating shaft 60 through a mounting base. Specifically, the mounting base has a through hole that matches the cross-section of the rotating shaft 60. Therefore, the rotating shaft 60 can drive the mounting base to rotate, and the mounting base drives the male mold head to rotate. The connection between the rotating shaft 60 and the grinding mechanism 10 is prior art and will not be described in detail here. The female grinding head 12 is mounted on the housing 20, and the male grinding head 11 is located inside the female grinding head 12. The male grinding head 11 can rotate coaxially with respect to the female grinding head 12. The material passing between the outer side of the grinding head and the inner side of the male grinding head 11 is ground. After the material is ground and becomes smaller, it will fall out of the gap between the outer side of the male grinding head 11 and the inner side of the female grinding head 12 due to gravity, thus realizing the grinding function.

[0031] In one embodiment, the peripheral wall of the rotating shaft 60 is provided with a limiting protrusion 61, and the end of the bracket 64 away from the spring 62 abuts against the limiting protrusion 61 of the spring 62.

[0032] like Figure 2 As shown, the rotating shaft 60 has a flat, locating protrusion 61 in the middle. The flat surface of the locating protrusion 61 is parallel to the central axis of the rotating shaft 60. This structure, compared to a design where the flat surface is perpendicular to the central axis of the rotating shaft 60, allows the first locating protrusion to withstand more axial force on the rotating shaft 60 with less material. In a preferred embodiment, the rotating shaft 60 and the locating protrusion 61 are integrally formed using stamping technology. In other embodiments, multiple locating protrusions 1 can be provided, for example, two. The two locating protrusions are symmetrically arranged on both sides of the rotating shaft 60, and can both abut against the bracket 64, restricting the axial movement of the rotating shaft 60. This method reduces the need for slotting on the rotating shaft 60 and the use of locating plates, while maintaining the strength of the rotating shaft 60 in transmitting torque, reducing material usage, simplifying the assembly process, and lowering manufacturing costs.

[0033] In one embodiment, the grinder 100 further includes a gasket 63, which is installed between the limiting protrusion 61 and the bracket 64. The limiting protrusion 61 abuts against one side of the gasket 63, and the other side of the gasket 63 abuts against the bracket 64. To prevent the limiting protrusion 61 from passing through the rotation hole, the inner diameter of the through hole in the gasket 63 can be set smaller than the diameter of the rotating shaft 60 plus the diameter of the limiting protrusion 61. The limiting protrusion 61 abuts against the gasket 63, and the gasket 63 restricts the axial movement of the rotating shaft 60. The gasket 63 also restricts the direct friction between the limiting protrusion 61 and the bracket 64, reducing wear. To further reduce the friction between the gasket 63 and the limiting protrusion 61, the portion of the gasket 63 in contact with the limiting protrusion 61 can be made of a flexible material, or the gasket 63 can be composed of a combination of a flexible pad and a rigid pad; no limitation is made here.

[0034] In one embodiment, the grinder 100 further includes a rotating cap 70, which is sleeved on the rotating shaft 60 and abuts against the bracket 64 and the spring 62. A bearing is provided at the end of the rotating cap 70 facing the spring 62, and the bearing abuts against the spring 62. Thus, one end of the bracket 64 cooperates with a limiting protrusion 61 on the rotating shaft 60 to limit the position of the rotating shaft 60; the other end cooperates with the rotating cap 70 to limit the position of the adjusting spring 62. The cooperation between the rotating shaft 60 and the rotating cap 70 can improve the rotational stability of the rotating shaft 60. Furthermore, a bearing can be provided at the position of the rotating cap 70 to reduce friction between the spring 62 and the rotating cap 70, extending its service life.

[0035] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
