Description

Technical Field

[0001] This utility model relates to the field of coffee processing equipment technology, and more specifically to a tumbler-type coffee tamper. Background Technology

[0002] Semi-automatic coffee machines allow users to select the amount of coffee grounds and the tamping pressure to provide different flavors, hence they are considered truly professional coffee machines. Currently, the tamper of semi-automatic pressure coffee machines generally tamps the coffee grounds using the flat surface at the bottom of the tamper holder, such as the horizontal constant tamper disclosed in Chinese Patent No. CN213189231U. While this has the advantage of maintaining a constant level of coffee inside the portafilter and improving tamping efficiency, the fact that the tamper stands upright on the flat surface of the bottom of the holder after tamping makes it prone to accumulating dust, which is unhygienic and affects the performance of subsequent tamping operations. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a self-righting powder tamper that can be placed upside down and is not easy to push over, and does not need to stand on a powder tamper stand, thus ensuring that the powder tamper stand is clean and hygienic.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a tumbler-type powder tamper, including a handle and a powder tamper base, the top of the handle is provided with a protruding hemispherical handle head, and the bottom of the handle is connected to the powder tamper base; the weight of the hemispherical handle head is greater than the total weight of the handle and the powder tamper base.

[0005] This technical solution provides a self-righting tamper, which features a heavy-weight hemispherical handle head at the top of the handle, creating a self-righting design. This allows the tamper to stand upside down, preventing it from tipping over and avoiding dirt buildup caused by the tamper standing flat, which could affect the tamping performance of subsequent tamping cycles. Simultaneously, the weight of the hemispherical handle head provides greater tamping force, ensuring compacted coffee grounds, reducing extraction channel effects, improving extraction uniformity and stability, and guaranteeing coffee quality. Furthermore, the self-righting structure of the tamper increases its playability.

[0006] In a preferred embodiment, the hemispherical handle head includes a handle cover and a counterweight, with the handle cover, handle, and powder hammer seat connected sequentially from top to bottom; the handle cover is a hemispherical hollow structure, and the counterweight is a hemispherical solid structure, with the counterweight fixedly installed inside the handle cover.

[0007] This technology uses a hemispherical hollow handle cover and a hemispherical solid counterweight to form a hemispherical handle head, realizing a roly-poly structure with vertical gravity and the ability to swing freely. The structure is simple and highly practical.

[0008] In a preferred embodiment, the weight of the counterweight is greater than the total weight of the handle and the powder hammer base. The gravity of the counterweight can provide greater powder pressing force, increase the powder pressing intensity, and improve the uniformity and stability of extraction.

[0009] In a preferred embodiment, the weight of the counterweight is not less than 75% of the total weight of the self-righting powder tamper, and the diameter of the counterweight is not less than one-third of the total height of the self-righting powder tamper. Under this ratio, the center of gravity of the self-righting powder tamper is close to the horizontal plane, thus achieving the goal of not tipping over.

[0010] In a preferred embodiment, the handle cover and the counterweight are fixedly connected by screws, which provides high connection strength and allows for easy disassembly and maintenance.

[0011] In a preferred embodiment, the handle cover has screw holes, and the counterweight has screw holes corresponding to the screw holes. Screws pass through the screw holes and screw holes to fix the counterweight inside the handle cover. The structure is simple, the connection is reliable, and the assembly and disassembly are convenient.

[0012] In a preferred embodiment, the handle cover and the handle are connected by an ultrasonic process to ensure a tight seal between them, preventing external dust and other contaminants from entering the handle and thus helping to extend the product's lifespan.

[0013] In a preferred technical solution, the handle and the powder hammer seat are connected by a threaded connection, which has the advantages of simple structure, high reliability, and convenient assembly and disassembly.

[0014] In a preferred embodiment, the bottom of the handle has an internal thread, and the top of the powder hammer seat has an external thread, with the internal and external threads engaging. In this technology, the handle and the powder hammer seat are connected via the internal and external threads, resulting in easy installation and low production costs.

[0015] In a preferred embodiment, the handle is hollow, which reduces its weight and provides better anti-tipping protection.

[0016] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of this utility model are as follows: The tamper provided by this utility model has a self-righting design by setting a heavy-weight hemispherical handle head at the top of the handle, which makes the tamper stand upside down and not easy to push over. This avoids the tamper from standing on a flat surface, resulting in uncleanliness and affecting the tamping performance of the next tamping. At the same time, the weight of the hemispherical handle head can provide greater tamping force, ensuring that the coffee powder is compacted, reducing the extraction channel effect, improving the uniformity and stability of extraction, and ensuring the quality of coffee. In addition, the self-righting structure of the tamper increases its playability.

[0017] In addition, other advantages of this invention will be set forth in the description which follows, and in part will be obvious from the description or may be learned by practice of this invention. Attached Figure Description

In specific implementation, the hemispherical handle head is fixedly connected to the top of the handle 3, and the powder hammer seat 4 is fixedly connected to the bottom of the handle 3. The roly-poly powder hammer forms a roly-poly structure when placed upside down.

[0029] The tamper provided in the above embodiments features a self-righting tamper with a heavy-weight hemispherical handle head at the top of the handle 3, forming a self-righting structure. This allows the tamper to stand upside down, preventing it from tipping over and avoiding dirt buildup caused by the tamper standing flat, which could affect the tamping performance in subsequent tamping cycles. Simultaneously, the weight of the hemispherical handle head provides greater tamping force, ensuring compacted coffee grounds, reducing extraction channel effects, improving extraction uniformity and stability, and guaranteeing coffee quality. Furthermore, the tamper's self-righting structure increases its playability.

[0030] In this embodiment, the hemispherical handle head includes a handle cover 1 and a counterweight 2.

[0031] The handle cover 1 is placed on the top of the handle 3, and the bottom of the handle 3 is fixedly connected to the powder hammer seat 4.

[0032] The above embodiment uses a hemispherical hollow handle cover 1 and a hemispherical solid counterweight 2 to form a hemispherical handle head, realizing a roly-poly structure with vertical gravity and the ability to swing arbitrarily. The structure is simple and highly practical.

[0033] In this embodiment, the weight of the counterweight 2 is greater than the combined weight of the handle 3 and the powder hammer seat 4. The gravity of the counterweight 2 provides greater pressing force, increasing the pressing intensity and improving extraction uniformity and stability.

[0034] In this embodiment, the weight of the counterweight 2 is not less than 75% of the total weight of the self-righting powder tamper, and the diameter of the counterweight 2 is not less than one-third of the total height of the self-righting powder tamper. Under this ratio, the center of gravity of the self-righting powder tamper is close to the horizontal plane, thus achieving the goal of not tipping over. In this embodiment, the handle cover 1 and the counterweight 2 are fixedly connected by screws, which provides high connection strength and allows for easy disassembly and maintenance.
