Technical Field
[0001] This utility model relates to the field of tobacco processing equipment technology, and in particular to a tobacco grinder. Background Technology
[0002] A tobacco grinder is an everyday tool used to grind materials such as tobacco leaves and herbs into fine particles. It typically consists of a rotating top cover and a container to hold the material. Rotating grinding teeth are located inside the top cover, while a fixed grinding seat is located inside the container. By rotating the top cover, the rotating grinding teeth and the fixed grinding teeth on the fixed grinding seat engage in a shearing action, thus grinding the material. The ground fine particles fall through grinding holes on the fixed grinding seat into a collection chamber below for easy retrieval by the user.
[0003] Currently, most cigarette grinders on the market use a one-piece structure for the fixed grinding base, meaning the fixed grinding teeth and the disc with grinding holes are an inseparable unit. This structure has two significant drawbacks: First, there's the issue of high replacement costs and poor economic efficiency. After prolonged use, the grinding teeth become dull due to wear, or the grinding holes become clogged with fine material residue that's difficult to clean thoroughly, directly leading to decreased grinding efficiency and uneven grinding particles. In this case, the user must replace the entire fixed grinding base along with its support, resulting in unnecessary waste and increased operating costs.
[0004] Secondly, there is the problem of limited functionality and lack of flexibility. Different users have different preferences for the fineness of the ground material, which is mainly determined by the diameter and shape of the grinding holes. In a one-piece structure, the specifications of the grinding holes are fixed. If users want to obtain particles of different fineness, they must purchase multiple complete smoke grinders or one-piece grinding bases of different specifications. This greatly limits user choices and further increases the economic burden of use. Therefore, based on the above-mentioned shortcomings of the existing technology, there is an urgent need for a new smoke grinder structure. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a smoke grinder.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a smoke grinder, comprising a rotatable upper cover and a canister, wherein the upper cover has rotating grinding teeth on its inner side; the canister has a detachable fixed grinding seat, which shears into the rotating grinding teeth and divides the canister cavity into an upper grinding chamber and a lower collection chamber; the fixed grinding seat includes a stacked and separable grinding support and a grinding disc; the grinding support has a plurality of fixed grinding teeth protruding from it and shearing into the rotating grinding teeth; the grinding disc has an insertion hole for the fixed grinding teeth to pass through and grinding holes distributed around the insertion hole; the canister has a limiting step on its inner wall, and the fixed grinding seat is supported on the limiting step; the canister has an internal thread below the limiting step, and a limiting ring is threadedly connected to the internal thread to axially press and fix the fixed grinding seat on the limiting step.
[0007] As a preferred embodiment of the present invention, the grinding bracket includes an outer ring portion, a mounting portion located at the center of the outer ring portion, and a plurality of connecting ribs connecting the outer ring portion and the mounting portion; the fixed grinding teeth are spaced apart on the connecting ribs.
[0008] As a preferred embodiment of this utility model, a notch is formed between adjacent connecting ribs; all the grinding holes on the grinding disc are located within the projection area of the notch.
[0009] As a preferred embodiment of the present invention, the mounting part is provided with a first magnetic suction member, and the center of the upper cover is provided with a second magnetic suction member that magnetically engages with the first magnetic suction member.
[0010] As a preferred embodiment of this utility model, the tank body includes an upper tank, a middle tank, and a bottom cover connected sequentially from top to bottom; the limiting step and the internal thread are provided on the inner wall of the upper tank; the fixed grinding seat is installed into the upper tank from bottom to top and supported by the limiting step, and the limiting ring is threadedly connected to the upper tank to press the fixed grinding seat; the upper end of the middle tank is threadedly connected to the upper tank, and the lower end is threadedly connected to the bottom cover.
[0011] As a preferred embodiment of this utility model, a filter screen is fixedly installed inside the intermediate tank.
[0012] 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 is arc-shaped and its two ends are hinged to the inner wall of the limiting ring; when the pull ring is flipped outward, part of its structure is exposed outside the limiting ring to form a hand-held force application part.
[0013] Compared with existing technologies, the advantages of this invention are: by designing the traditional integrated fixed grinding base as a detachable grinding bracket and grinding disc, users do not need to discard the still intact grinding bracket when only the grinding disc needs to be replaced due to wear, blockage, or a change in specifications. This avoids the waste caused by replacing the entire unit and greatly reduces the user's long-term operating costs and maintenance expenses.
[0014] By fixing the grinding teeth and inserting them into the socket, and combining the threaded locking structure of the limiting steps and limiting rings inside the tank, it is ensured that the grinding disc and grinding support will not misalign or wobble during operation. This design ensures both the convenience of separate parts and the stability of the integrated structure and the precision of the grinding and shearing action, thus guaranteeing long-lasting and efficient grinding performance.
[0015] Because the grinding disc is an independently replaceable component, it is easy to manufacture grinding discs with different pore sizes, shapes, and distribution densities. Users can easily change to different grinding discs according to their individual preferences for grinding coarseness, thus achieving various grinding effects from fine to coarse. One set of cigarette grinder can meet diverse needs, realizing product customization and personalization, and providing a better user experience. Attached Figure Description

[0018] 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.
[0019] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0020] like Figures 1 to 7A smoke grinder is shown, comprising a rotatable upper cover 1 and a canister 2. The upper cover 1 has rotating grinding teeth 3 on its inner side. The canister 2 has a detachable fixed grinding seat 4, which is shear-fitted with the rotating grinding teeth 3 and divides the inner cavity of the canister 2 into an upper grinding chamber 5 and a lower collection chamber 6. The fixed grinding seat 4 includes a grinding support 7 and a grinding disc 8 that are stacked and separable. The grinding support 7 has a plurality of fixed grinding teeth 9 that shear-fitted with the rotating grinding teeth 3. The grinding disc 8 has an insertion hole 10 through which the fixed grinding teeth 9 pass and grinding holes 11 distributed around the insertion hole 10. The inner wall of the canister 2 has a limiting step 12, and the fixed grinding seat 4 is supported on the limiting step 12. The inner wall of the canister 2 has an internal thread below the limiting step 12, and a limiting ring 13 is threaded to the internal thread to axially press and fix the fixed grinding seat 4 onto the limiting step 12. In this application, since the grinding disc 8 is an independently replaceable component, grinding discs 8 with different apertures, shapes, and distribution densities can be easily produced. Users can easily replace different grinding discs 8 according to their individual preferences for grinding coarseness, thereby achieving various grinding effects from fine to coarse particles. One set of cigarette grinder can meet diverse needs, realizing product customization and personalization, and providing a better user experience. By designing the traditional integrated fixed grinding base 4 as a separable grinding bracket 7 and grinding disc 8, when only the grinding disc 8 needs to be replaced due to wear, blockage, or a change in specifications, the user does not need to discard the still intact grinding bracket 7. This avoids the waste caused by replacing the entire unit and greatly reduces the user's long-term usage costs and maintenance expenses. In this embodiment, the fixed grinding teeth 9 and the rotating grinding teeth 3 adopt a staggered shearing grinding principle. This working principle is a conventional technical means in the field and is not the innovation of this application, so it will not be described in detail here. It should be noted that this application does not limit the specific shape of the fixed grinding teeth 9. As an example, the cross-sectional shape of the fixed grinding teeth 9 can be, but is not limited to, any feasible geometric shape such as trapezoid, triangle, or rectangle. Similarly, the shape of the grinding holes 11 on the grinding disc 8 is not specifically limited; they can be circular, polygonal, or any other geometric shape. Any design that enables the grinding of materials with qualified particle sizes to be screened into the collection chamber 6 falls within the protection scope of this application. The above examples of shapes are merely illustrative and should not be construed as limiting the protection scope of this application.
[0021] By fixing the grinding teeth 9 and inserting them into the holes 10, and combining this with the threaded locking structure of the limiting step 12 and the limiting ring 13 inside the tank body 2, it is ensured that the grinding disc 8 and the grinding bracket 7 will not misalign or wobble during operation. This design ensures both the convenience of separate parts and the stability of the integrated structure and the precision of the grinding and shearing action, thus guaranteeing long-lasting and efficient grinding performance.
[0022] The grinding bracket 7 includes an outer ring portion 14, a mounting portion 15 located at the center of the outer ring portion 14, and a plurality of connecting ribs 16 connecting the outer ring portion 14 and the mounting portion 15; the fixed grinding teeth 9 are spaced apart on the connecting ribs 16.
[0023] A notch 17 is formed between adjacent connecting ribs 16; all grinding holes 11 on the grinding disc 8 are located within the projection area of the notch 17. This design ensures that the top of each grinding hole 11 is directly opposite the notch 17 space of the support, forming a vertical and smooth material drop channel. Grinded material particles can fall directly through the grinding holes 11 without any obstruction, effectively preventing material accumulation or blockage above the grinding disc 8, thereby significantly improving grinding efficiency and material discharge smoothness.
[0024] The mounting part 15 is provided with a first magnetic attractor 18, and the upper cover 1 has a second magnetic attractor 19 at its center that magnetically engages with the first magnetic attractor 18. One of the first magnetic attractor 18 and the second magnetic attractor 19 is a permanent magnet, and the other is a permanent magnet or a magnetic attractor made of a magnetic material (such as iron, cobalt, nickel, or their alloys) that can be attracted by the permanent magnet. In a preferred embodiment, both the first magnetic attractor 18 and the second magnetic attractor 19 are permanent magnets, and their opposing magnetic poles are opposite to generate the strongest magnetic attraction.
[0025] The tank body 2 includes an upper tank 20, a middle tank 21, and a bottom cover 22 connected sequentially from top to bottom; the limiting step 12 and the internal thread are provided on the inner wall of the upper tank 20; the fixed grinding seat 4 is installed into the upper tank 20 from bottom to top and supported by the limiting step 12, and the limiting ring 13 is threadedly connected to the upper tank 20 to press and fix the grinding seat 4; the upper end of the middle tank 21 is threadedly connected to the upper tank 20, and the lower end is threadedly connected to the bottom cover 22. In this embodiment, a filter screen 23 is fixedly installed inside the tank 21.
[0026] A flip-out pull ring 24 is provided in the center of the limiting ring 13. The pull ring 24 is arc-shaped and its two ends are hinged to the inner wall of the limiting ring 13. When the pull ring 24 is flipped outward, part of its structure is exposed on the limiting ring 13 to form a hand-held force application part, which makes it convenient for the user to twist the limiting ring 13 and provides convenience for the user.
[0027] 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.
