[0002] A grinder is a tool used to process materials, medicinal herbs, or plants. It typically grinds materials, medicinal herbs, or plants using blades or similar tools.

[0003] Most existing grinding machines grind materials, medicinal herbs, or plants into fine powder particles. To achieve larger particles, grinding time needs to be controlled. However, even with this method, some particles remain larger than others, resulting in uneven grinding. For example, the grinding head assembly disclosed in CN222624770U includes: a grinding body equipped with a rotating component to drive its rotation; a guide section located at the end of the grinding body, forming a downward-facing first guide path from the end towards the center; a grinding head positioned below the guide section, forming a second guide path; and a guide surface above the guide section, extending outward from the grinding body. In a top view, the guide surface has a structure that is wider in the middle and narrower at both ends, forming a curved guide surface from the middle towards both ends. This invention features a guide section at the end, forming a downward-facing guide path, allowing the material to be ground, including plants and other medicinal herbs, at the assembly points of the grinding head assembly and assembly cavity to enter the grinding head below the grinding body via the guide path, thus achieving grinding.

[0004] The aforementioned grinding head cannot control the particle size of the processed items during grinding, resulting in some items being large particles and others being fine powder, which cannot meet the user's need to process items that are not too fine. Utility Model Content

[0029] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0030] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0033] In one embodiment of this utility model, according to Figure 1-5 As shown, it includes a cutting shaft 310; the cutting shaft 310 has a connecting hole 311 in the middle, which can be a through hole or a blind hole, preferably a through hole. Two cutting heads 320 are horizontally arranged on both sides of the connecting hole 311, with two on each side in the horizontal direction centered on the connecting hole 311. There is a gap 330 between two adjacent cutting heads 320 on the same side. When the cutting shaft 310 rotates, the cutting heads 320 can cut and abrasive materials, and the gap 330 between two adjacent cutting heads 320 can control the particle size of the material.

[0034] Specifically, by horizontally arranging multiple cutting heads 320 on the cutting shaft 310, materials can be cut and ground. There is a gap 330 between two adjacent cutting heads 320 on the same side. Materials in the gap 330 will not be cut, thus controlling the particle size of the material. The cutting head 320 only has a cutting effect within a certain diameter range, unlike general blades on the market which indiscriminately cut and grind all objects in the cavity. General blades on the market are used for fine grinding, while the function of this cutting head 320 is relatively limited to cutting, reducing the grinding function to avoid grinding too finely, thereby achieving particle size control.

[0035] The cutting head 320 and the cutting shaft 310 are fixedly connected. The fixed connection can be integrally formed, or it can be fixed by welding, screwing, or other methods.

[0036] In another embodiment of this utility model, according to Figure 1 As shown, each cutting head 320 includes a base portion 321 and a cutting edge portion 322 connected to the base portion 321. The cutting edge portion 322 is disposed on the base portion 321 and can cut abrasive materials when rotated. Each cutting head 320 is disc-shaped, with the base portion 321 in the center being circular. The cutting edge portion 322 is arranged in a ring around the outer circumference of the base portion 321, and its main function is cutting. The circumferential direction of the cutting edge portion 322 is consistent with the circumferential direction of the cutting axis 310. It can be considered that the cutting axis 310 passes through the base portion 321. This structure allows the cutting edge portion 322 to cut abrasive materials when the cutting axis 310 rotates.

[0037] In another embodiment of this utility model, according to Figure 1 As shown, the connection between the base portion 321 and the cutting shaft 310 has a smooth transition. Sharp right-angle connections can easily lead to stress concentration, especially during high-speed rotation. A smooth transition can reduce the risk of fatigue cracks by distributing the load, thus extending the service life of the cutting head 320. Gradual transitions avoid abrupt changes in cross-section, maintain material continuity, improve the material's resistance to torsional loads, and prevent the cutting head 320 from breaking.

[0038] In another embodiment of this utility model, according to Figure 1 As shown, the cutting head 320 and the cutting shaft 310 are integrally formed. Specifically, compared with traditional welding and screw connections, the integral forming has a longer service life and a more stable structure.

[0039] In another embodiment of this utility model, according to Figure 1As shown, the two ends of the cutting shaft 310 are respectively provided with protrusions 340, and the cutting head 320 is provided between the protrusions 340 and the connecting hole 311. When the cutting shaft 310 and the cutting head 320 are welded, the end needs to be provided with protrusions 340 for reinforcement to prevent the cutting head 320 from separating from the cutting shaft 310 when rotating due to structural loosening.

[0040] In another embodiment of this utility model, according to Figure 2-5 As shown, a grinding machine includes a grinding head 300, a first housing 100, and a second housing 200. The first housing 100 is detachably connected to the second housing 200. A motor 400 is housed inside the first housing 100, and a switch button 130 is provided on the first housing 100 to control the start and stop of the motor 400. An output shaft 410 is connected to the output end of the motor 400. The output shaft 410 can extend into the second housing 200 and be inserted into a connection hole 311 to connect with the grinding head 300. When the motor 400 is turned on by the switch button 130, the motor 400 can drive the grinding head 300 to rotate, thereby cutting and grinding the material.

[0041] The first housing 100 is threadedly connected to the second housing 200. The second housing 200 can be rotated to separate from the first housing 100. The material to be ground is added into the second housing 200 and then connected to the first housing 100 for grinding.

[0042] Furthermore, the connection between the output shaft 410 and the cutting shaft 310 can be a screw connection, with the connection hole 311 being a through hole, through which the output shaft 410 is screwed, and then secured with a nut.

[0043] In another embodiment of this utility model, according to Figure 2-5 As shown, a base 140 is provided inside the first housing 100. A first placement position 141 and a second placement position 142 are provided on the base 140. The motor 400 is located in the first placement position 141, and a battery compartment 500 is located in the second placement position 142. A cover 150 is provided on the base 140, forming a receiving cavity between the cover 150 and the base 140 to accommodate the motor 400, thus securing the battery compartment 500 and the motor 400. It can be understood that the base 140 has an opening 143 through which the output shaft 410 of the motor 400 can extend into the second housing 200. Simultaneously, the cover 150 has an opening 151 through which one end of the motor 400 extends and connects to the switch button 130.

[0044] It is understood that the first housing 100 is also equipped with a charging head 160, which is connected to a circuit board, which is located inside the cover 150. The connection method between the circuit board, the battery compartment 500 and the motor 400 is conventional technology for those skilled in the art and will not be described in detail here. At the same time, the base 140 and the cover 150 are connected by at least two connecting posts 144.

[0045] Furthermore, the first housing 100 is divided into a main body 110 and a top cover 120, which are detachably connected, specifically by magnetic attraction, snap-fit, threaded connection, or screw connection. A switch button 130 is located on the top cover 120.

[0046] In another embodiment of this utility model, according to Figure 4 and 5 As shown, a sensor is also provided on the base 140, and the circuit board is electrically connected to the sensor. The sensor is used to sense the internal conditions of the second housing 200.

[0047] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
