Description

Technical Field

[0001] This utility model relates to the field of coffee equipment technology, specifically to a gravity powder dispenser. Background Technology

[0002] After grinding coffee beans, they need to go through steps such as spreading and tamping. In the past, spreading the coffee powder was mostly done manually. Now, technology has given rise to the "magical tool" of a coffee spreader. It can evenly spread the coffee powder in the portafilter and precisely fill in the hard-to-see holes at the bottom, making the coffee powder more evenly distributed, improving the quality of coffee making, and allowing enthusiasts to easily make professional-level coffee at home, satisfying people's pursuit of high-quality coffee.

[0003] Existing coffee powder dispensers have certain limitations in their structural design, with most only having a bearing at the connection between the support base and the connecting shaft. While these devices achieve a degree of automation in powder distribution by utilizing gravity and rotation, long-term practical application has revealed numerous drawbacks. For example, because the connecting shaft is supported by only a single bearing at the bottom, it is prone to imbalance during rotation, especially when facing resistance changes caused by uneven distribution of coffee powder, and due to the unavoidable uneven force applied by the user during manual operation. This directly leads to tilting of the connecting shaft, causing severe jamming, which not only disrupts the smoothness of powder distribution, preventing even distribution, but also significantly increases the difficulty and frustration for the user.

[0004] Furthermore, from the perspective of mechanical structure durability, the single bearing design concentrates all the load when the connecting shaft is in operation on the bottom bearing. Under long-term high-intensity use, the bearing wear will accelerate rapidly, and the frequent friction and collision between components will generate additional stress, which will greatly shorten the service life of the device, increase maintenance costs and frequency, and cause a lot of inconvenience to users.

[0005] Based on this, a novel gravity powder distributor has been developed in this utility model, which has solved the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this utility model is to provide a gravity powder distributor. This gravity powder distributor, by setting corresponding first and second bearing mounting positions on the support base and the top cover respectively and installing bearings, allows the connecting shaft to run under the precise support and guidance of the double bearings. This avoids the tilting problem caused by uneven force on the connecting shaft, ensures the coaxiality of the connecting shaft during rotation, greatly reduces jamming, and makes the powder distribution process smooth and unobstructed.

[0007] This utility model is achieved through the following technical solution: a gravity powder distributor, comprising:

[0008] A support base, wherein a first bearing mounting position is formed in the middle of the support base, and a first bearing is installed in the first bearing mounting position;

[0009] A top cover, wherein a second bearing mounting position is formed in the middle of the top cover; the second bearing mounting position is disposed opposite to the first bearing mounting position, and a second bearing is mounted thereon;

[0010] A connecting shaft, from top to bottom, includes a second bearing connecting part, a first bearing connecting part, and a gravity powder distribution component connecting part; wherein, the second bearing connecting part of the connecting shaft is connected to the second bearing, and the first bearing connecting part of the connecting shaft is connected to the first bearing;

[0011] A gravity powder distribution component is disposed at the bottom of the support base and connected to the gravity powder distribution component connecting part on the connecting shaft.

[0012] Furthermore, the outer wall of the top cover is provided with anti-slip texture along its circumference.

[0013] Furthermore, the anti-slip texture is a long strip-shaped groove structure, evenly spaced along the circumference of the top cover.

[0014] Furthermore, the upper surface of the top cover is provided with through holes distributed in a vortex pattern.

[0015] Furthermore, the gravity powder distributor also includes:

[0016] The limiting member has an internal thread on its inner wall, which is threaded to the external thread on the outer wall of the support base to adjust the installation height of the limiting member; a limiting part is formed on the outer wall at the bottom end of the limiting member to limit the top cover.

[0017] Furthermore, the limiting part is an annular flange structure that mates with the bottom end of the top cover.

[0018] Furthermore, a sealing ring is provided between the gravity powder distribution component connecting part on the connecting shaft and the gravity powder distribution component.

[0019] The beneficial effects of this utility model are:

[0020] This gravity powder distributor, as described in this invention, features a connecting shaft that operates under the precise support and guidance of two bearings by installing corresponding first and second bearing mounting positions on the support base and top cover. Compared to traditional designs with only a bearing at the bottom, this double-bearing structure effectively avoids the tilting problem caused by uneven force on the connecting shaft, ensures the coaxiality of the connecting shaft during rotation, greatly reduces jamming, and makes the powder distribution process smooth and unobstructed, providing a stable mechanical foundation for high-quality powder distribution.

[0021] Meanwhile, the dual-bearing structure distributes the load on the connecting shaft during operation. Compared to a single-bearing design, the pressure on each bearing is relatively reduced, slowing down the wear rate. Furthermore, the stable operating state reduces additional stress caused by friction and collision between components, lowering the risk of component damage and thus extending the service life of the entire powder distributor and reducing maintenance costs.

Detailed Implementation

[0029] All features disclosed in this specification, or steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps. Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0030] The following is in conjunction with the appendix Figure 1-5 The invention will be described in detail, including specific implementation methods.

[0031] like Figure 1-5 As shown, this utility model provides a gravity powder distributor, which includes:

[0032] A support base 1, wherein a first bearing mounting position 10 is formed in the middle of the support base 1, and a first bearing 2 is installed in the first bearing mounting position 10;

[0033] The top cover 3 has a second bearing mounting position 30 formed in the middle; the second bearing mounting position 30 is arranged opposite to the first bearing mounting position 10, and a second bearing 4 is installed thereon;

[0034] The connecting shaft 5 includes, from top to bottom, a second bearing connecting part 50, a first bearing connecting part 51, and a gravity powder distribution component connecting part 52; wherein, the second bearing connecting part 50 of the connecting shaft 5 is connected to the second bearing 4, and the first bearing connecting part 51 of the connecting shaft 5 is connected to the first bearing 2.

[0035] Gravity powder distribution component 6 is disposed at the bottom of the support base 1 and is connected to the gravity powder distribution component connecting part 52 on the connecting shaft 5.

[0036] The general assembly process of this gravity powder distributor is as follows: First, the first bearing 2 is installed in the first bearing mounting position 10 in the middle of the support base 1, providing a stable support point for the subsequent linkage of components. Next, the second bearing 4 is installed on the second bearing mounting position 30 in the middle of the top cover 3, following strict assembly standards to ensure that its position is accurate and the installation is firm. After this step is completed, the upper and lower bearing positions correspond, laying the foundation for the smooth installation and operation of the connecting shaft 5. Then, the connecting shaft 5 is introduced, and its second bearing connecting part 50 is precisely matched with the inner ring of the second bearing 4 on the top cover 3 from top to bottom, so that the top of the connecting shaft 5 obtains stable guidance and support; at the same time, the first bearing connecting part 51 of the connecting shaft 5 is tightly connected with the inner ring of the first bearing 2 on the support base 1, ensuring that the bottom of the connecting shaft 5 can also rotate flexibly. Thus, the connecting shaft 5 can rotate freely and smoothly around the axis under the synergistic action of the two bearings. Finally, firmly connect the gravity powder distribution component 6 to the gravity powder distribution component connection part 52 of the connecting shaft 5, so that the gravity powder distribution component 6 can move synchronously with the connecting shaft 5. At this point, the entire gravity powder distributor assembly is complete.

[0037] When preparing to distribute the coffee powder, the top cover 3 can be manually rotated to apply an appropriate rotational force, and the connecting shaft 5 will begin to rotate around its axis. As the connecting shaft 5 rotates, the gravity-fed powder distribution component 6, which is rigidly connected to it, also rotates synchronously. The gravity-fed powder distribution component 6 relies on its own gravity to press the coffee powder downwards, thus achieving the effect of tamping the coffee powder.

[0038] In this invention, the gravity powder distributor features a dual-bearing structure. By installing bearings at corresponding first and second bearing mounting positions on the support base 1 and top cover 3, the connecting shaft 5 operates under precise support and guidance from the dual bearings. Compared to traditional designs with only a bearing at the bottom, this dual-bearing structure effectively avoids tilting issues caused by uneven force on the connecting shaft 5, ensuring coaxiality during rotation, significantly reducing jamming, and providing a smooth and unobstructed powder distribution process, thus offering a stable mechanical foundation for high-quality powder distribution.

[0039] Meanwhile, the dual-bearing structure distributes the load on the connecting shaft 5 during operation. Compared to a single-bearing design, the pressure on each bearing is relatively reduced, slowing down the wear rate. Furthermore, the stable operating state reduces additional stress caused by friction and collision between components, lowering the risk of component damage and thus extending the service life of the entire powder distributor and reducing maintenance costs.

[0040] Furthermore, in some specific embodiments, the outer wall of the top cover 3 is provided with anti-slip texture along its circumference for anti-slip function. In this embodiment, the anti-slip texture is a long strip-shaped groove structure 31, which is evenly spaced along the circumference of the top cover 3. When the user manually rotates the top cover 3 to drive the powder dispenser, the fingers come into contact with the outer wall of the top cover 3. The long strip-shaped groove structure 31 can effectively increase the friction between the hand and the top cover, allowing the fingers to grip the top cover more firmly. Compared with a smooth outer wall, even when the hands are sweaty or in a humid environment, the user can easily apply force, avoiding rotational operation errors due to hand slippage, ensuring that the power is transmitted accurately and smoothly each time the top cover 3 is rotated, allowing the connecting shaft 5 and the gravity powder dispensing component 6 to operate stably as expected, ensuring the continuity and uniformity of the powder dispensing process. At the same time, the long strip-shaped groove structure 31 is evenly spaced along the circumference, giving the top cover 3 a unique aesthetic appearance.

[0041] Furthermore, in some specific embodiments, the upper surface of the top cover 3 has through holes 32 distributed in a vortex pattern, or in other words, distributed in a windmill-like pattern. The through holes 32 reduce the weight of the top cover 3 while enhancing its aesthetic appeal. In this embodiment, six through holes 32 are provided.

[0042] Furthermore, in some specific embodiments, the gravity powder distributor also includes a limiting member 7. The inner wall of the limiting member 7 has an internal thread 70, which forms a threaded connection with the external thread 11 on the outer wall of the support base 1, thereby allowing adjustment of the installation height of the limiting member 7. In use, the limiting member 7 can be flexibly rotated to adjust its installation height on the support base 1.

[0043] Meanwhile, a limiting part 71 is formed on the outer wall of the bottom end of the limiting member 7 to limit the top cover 3. In this embodiment, the limiting part 71 is an annular flange structure that cooperates with the bottom end of the top cover 3. When the user manually rotates the top cover 3 to distribute powder, the connecting shaft 5 will also rotate accordingly. At this time, due to the presence of the limiting member 7, especially the limiting effect of its limiting part 71 on the top cover 3, the top cover 3 can only move within a limited vertical range, and there will be no excessive downward displacement, ensuring the stability of the entire powder distributor during operation.

[0044] Furthermore, in some specific embodiments, a sealing ring is provided between the gravity powder distribution component connecting part 52 on the connecting shaft 5 and the gravity powder distribution component 6 to enhance the connection sealing and prevent coffee powder and other substances from flowing into the powder distributor from the connection between the connecting shaft 5 and the gravity powder distribution component 6, thus affecting the product's service life.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
