[0005] As a preferred technical solution of this utility model, the lateral sliding latch structure includes a guide groove on the side wall of the upper cover and a protrusion on the rotating grinding teeth, wherein the guide groove and the protrusion constitute a sliding insertion fit.
[0006] As a preferred embodiment of this utility model, the guide groove is a dovetail groove, and the protrusion is a dovetail block adapted to the shape of the dovetail groove.
[0007] As a preferred technical solution of this utility model, the lateral sliding latch structure is further provided with a magnetic adsorption unit, including a first magnetic adsorption member embedded in the guide groove and a second magnetic adsorption member provided in the protrusion.
[0008] As a preferred technical solution of this utility model, the inner wall of the tank is provided with an internal thread corresponding to the collection chamber area. The axial constraint structure includes a limiting step on the inner wall of the tank and a limiting ring that mates with the internal thread. The bottom of the fixed grinding tooth abuts against the limiting step, and axial fixation is achieved through the threaded connection between the limiting ring and the internal thread of the tank.
[0009] As a preferred technical solution of this utility model, the center of the limiting ring is provided with a flip-out pull ring. The pull ring has an arc-shaped structure and its two ends are directly hinged to the inner wall of the limiting ring. After flipping, the arc-shaped part of the pull ring is exposed to form a hand-held force application part.
[0010] As a preferred embodiment of this utility model, the bottom of the tank is provided with a detachable bottom cover, which is connected to the tank by threads.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] The combination of the lateral sliding locking structure (dovetail groove + magnetic unit) and the threaded locking of the limiting ring enables quick assembly and disassembly of the rotating grinding teeth and the fixed grinding teeth, allowing users to replace worn parts individually.
[0013] After the grinding teeth are removed, the tank forms a through cavity, supporting two-way cleaning (rinsing from top to bottom or brushing from bottom to top). Attached Figure Description

[0023] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0025] like Figures 1 to 8 The illustrated tobacco grinder includes a rotatable upper cover 1 and a canister 2 with a through-cavity. The canister 2 has an opening at the top and a removable bottom cover 15 at the bottom, which is threadedly connected to the canister 2. The bottom of the upper cover 1 has removable rotating grinding teeth 3, which are interchangeably connected to the upper cover 1 via a lateral sliding locking structure. The canister 2 (preferably cylindrical) contains removable fixed grinding teeth 4, which are installed via an axial constraint structure on the inner wall of the canister 2 and are positioned opposite to the tooth surfaces of the rotating grinding teeth 3. The fixed grinding teeth 4 divide the inner cavity of the canister 2 into an upper grinding chamber 5 and a lower collection chamber 6. In this embodiment, the fixed grinding teeth 4 and the rotating grinding teeth 3 are preferably disc-shaped, with evenly distributed feeding holes on the fixed grinding teeth 4. The sheared and ground tobacco can enter the collection chamber 6 through these feeding holes. The tooth surface shapes of the fixed grinding teeth 4 and the rotating grinding teeth 3 are selected according to actual conditions. Their shearing working principle is relatively mature and is existing technology, therefore not specifically described.
[0026] The rotating grinding teeth 3 and the fixed grinding teeth 4 can be quickly disassembled and assembled through the cooperation of the lateral sliding locking structure (dovetail groove and magnetic unit) and the threaded locking of the limiting ring 12, allowing users to replace worn parts individually. After the fixed grinding teeth 4 are removed, the tank body 2 forms a through cavity, supporting bidirectional cleaning (rinsing from top to bottom or brushing from bottom to top).
[0027] The lateral sliding locking structure includes a guide groove 7 on the side wall of the upper cover 1 and a protrusion 8 on the rotating grinding teeth 3. The guide groove 7 and the protrusion 8 form a sliding insertion fit. In this embodiment, the guide groove 7 is preferably a dovetail groove, and the protrusion 8 is preferably a dovetail block adapted to the shape of the dovetail groove. It is not limited to this shape. The guide groove 7 can also be T-shaped, and the protrusion 8 is adapted to the shape of the guide groove 7.
[0028] The lateral sliding latch structure is also provided with a magnetic adsorption unit, including a first magnetic adsorption member 9 embedded in the guide groove 7 and a second magnetic adsorption member 10 provided in the protrusion 8. In this embodiment, the first magnetic adsorption member 9 and the second magnetic adsorption member 10 are magnets.
[0029] The inner wall of the tank 2 is provided with an internal thread corresponding to the area of the collection chamber 6. The axial constraint structure includes a limiting step 11 on the inner wall of the tank 2 and a limiting ring 12 that mates with the internal thread. The bottom of the fixed grinding tooth 4 abuts against the limiting step 11 and is axially fixed through the threaded connection between the limiting ring 12 and the internal thread of the tank 2, which can realize the replacement of the fixed grinding tooth 4.
[0030] The center of the limiting ring 12 is provided with a flip-out pull ring 13. The pull ring 13 has an arc-shaped structure and its two ends are directly hinged to the inner wall of the limiting ring 12. After flipping, the arc-shaped part 14 of the pull ring 13 is exposed to form a hand-held force application part. In the use state, the pull ring 13 is parallel to the axial direction of the limiting ring 12. The limiting ring 12 can be removed by rotating the pull ring 13.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples of this utility model and are not intended to limit it. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
