[0002] A coffee powder dispenser is a structure used for distributing, compacting, and leveling coffee powder. It mainly uses a corresponding lifting structure to drive the cloth head seat to rotate. For example, CN202323131813.8 shows a gravity-driven spiral telescopic powder dispenser, which includes an upper cover, a knob embedded in the upper inner side of the upper cover, and a fan-shaped upper vent hole at the upper rear side of the knob. A lower cover is provided at the lower end of the upper cover through a threaded insert, and a powder dispensing head is embedded in the inner side of the lower cover. The above structure can meet the needs of powder application to some extent, but its overall structural stability is limited, and it is also prone to jamming during operation, affecting the effectiveness of powder application and making it difficult to meet market demand, thus limiting its applicability. Summary of the Invention

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0015] See Figures 1 to 4 As shown, a gravity-fed self-pressurized powder distributor includes a fixed base 1, an adjusting ring 2 disposed on the top surface of the fixed base, and a powder distribution seat 3 disposed below the fixed base. A support seat 4 is disposed inside the adjusting ring. In this embodiment, the fixed base and the adjusting ring are fixed by a threaded connection, or they can be fixed by screw locking. The support seat is connected to the adjusting ring by a thread, or it can be positioned by other methods. The powder distribution seat is a conventional structure in the prior art, and it is simply applied in a basic way.

[0016] In this embodiment, a connecting central shaft 5 is fixed on the powder distribution seat. The middle part of the connecting central shaft is rotatably connected to the fixed seat through a bearing 6 and passes through the center of the support seat. A rotating suspension lower sleeve 7 is fixed to the top of the connecting central shaft. The connecting central shaft and the powder distribution seat can be connected by threads or fixed by other methods such as screw locking. The connection between the connecting central shaft and the rotating suspension lower sleeve can also be locked by threads or screws. With the above structure, the connecting central shaft can rotate when the rotating suspension lower sleeve rotates, thereby ensuring the rotation effectiveness and reliability of the powder distribution seat. In this embodiment, a guide post 8 is fixed on the support base, and a pressing cover 9 is fixed to the top of the guide post. The height of the guide post can be set as needed, and there are three guide posts. A gravity-driven movable component 10 is provided between the support base and the pressing cover, and the guide post passes through the gravity-driven movable component. A concentric shaft 11 is fixed to the center of the bottom surface of the pressing cover, and a rotating suspension upper sleeve 12 is sleeved on the outer side of the concentric shaft. In this embodiment, the concentric shaft is fixed to the center of the bottom surface of the pressing cover by a screw. The gravity-driven movable component has a guide hole, and the guide post is located inside the guide hole. The guide post guides the descent of the gravity-driven movable component, ensuring the effectiveness of its lifting and lowering. The diameter of the rotating suspension upper sleeve matches the diameter of the rotating suspension lower sleeve. Furthermore, in practical applications, a spiral guide groove 13 is provided on the outer wall of the rotating suspension upper sleeve. The gravity movable component is sleeved on the outside of the rotating suspension upper sleeve, and a support ball 14 with its end extending into the spiral guide groove is fixed on the inner ring edge of the gravity movable component. The support ball is a conventional structure in the prior art, including a cylinder, a ball, and a compression spring, and is simply applied. In use, when the gravity movable component descends, the support ball moves within the spiral guide groove, driving the rotating suspension upper sleeve to rotate, which in turn drives the rotating suspension lower sleeve to rotate. The diameter of the support ball is smaller than the width of the spiral guide groove. The number of spiral guide grooves is two or three, and the number of support balls matches the number of spiral guide grooves.

[0017] Furthermore, in practical applications, a spring 15 is installed between the top surface of the powder distribution seat and the bottom surface of the fixed seat. To ensure the rotational effectiveness of the powder distribution seat, both the top surface of the lower rotating suspension sleeve and the bottom surface of the upper rotating suspension sleeve are equipped with one-way helical teeth 16. These one-way helical teeth are in opposite directions. When the upper rotating suspension sleeve rotates, the one-way helical teeth of the upper sleeve mesh with the one-way helical teeth of the lower rotating suspension sleeve. When the upper rotating suspension sleeve descends to its lowest point, the lower rotating suspension sleeve continues to rotate. Because of the use of one-way helical teeth, when the upper rotating suspension sleeve stops working, under inertia, the two one-way helical teeth will continue to rotate from the inclined side, ensuring the rotational effectiveness and stability of the lower rotating suspension sleeve, and saving manpower.

[0018] In this embodiment, a decorative cover 17 is provided on the top of the fixing base and the adjusting ring.

[0019] This utility model has positive effects: its structure is reasonably designed, with a concentric shaft fixed at the center of the bottom surface of the press cover, and a rotating suspension upper sleeve sleeved on the outer side of the concentric shaft; a spiral guide groove is provided on the outer wall of the rotating suspension upper sleeve, which, together with the gravity movable component and the support ball on the inner ring edge, allows the support ball to move in the spiral guide groove when the gravity movable component descends under the action of gravity, thereby driving the rotating suspension upper sleeve to rotate, and driving the rotating suspension lower sleeve to rotate together, realizing the rotation action of the powder distribution seat, completing the powder distribution, compaction and surface smoothing operations, improving the effectiveness and convenience of powder distribution, and the overall structure is simple, which helps to reduce processing costs, is stable and reliable in use, and has strong applicability.

[0020] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0021] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
