Description

Technical Field

[0001] This utility model belongs to the field of coffee pot technology, and specifically relates to a novel glass coffee pot. Background Technology

[0002] Current glass coffee makers generally suffer from insufficient precision in flow control. Traditional spouts have a simple structure and cannot dynamically adjust the coffee flow rate during pouring, making it difficult for users to accurately control the amount of water poured, easily leading to coffee splashing or flow interruptions. Especially in scenarios requiring precise operation, such as pour-over coffee, uncontrolled flow directly affects the uniformity of extraction and flavor profile. Although some products have attempted to improve this through complex valves, the structure is redundant and the operation is cumbersome, making it difficult to balance convenience and functionality. Therefore, there is an urgent need for a highly integrated and responsive flow control mechanism that can simplify operation while achieving linear and precise control of the coffee flow.

It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way. Example 1

[0030] like Figure 1-4 As shown, a novel glass coffee maker includes a pot body 1 and a lid 2. The lid 2 consists of a lid body 21 at the rear end and a flow-limiting part 22 at the front end. The flow-limiting part 22 has a vertical through hole 221 and a horizontal slot 222. A gear 225 and a rack 226 are installed in the slot 222. A rotating shaft 223 passes through the center of the gear 225. The rotating shaft 223 passes through the through hole 221 and is connected to a knob 224. A stop 227 is provided at the end of the rack 226. Rotating the knob 224 drives the stop 227 to move to adjust the flow rate of coffee liquid.

[0031] As a preferred embodiment of the present invention, a baffle 228 is provided at the front end of the through hole 221, and the baffle 228 covers the top of the rotating shaft 223.

[0032] As a preferred embodiment of the present invention, the lid 2 has a lid bottom surface 23, and side blocks 231 are symmetrically arranged on the edge of the lid bottom surface 23. Multiple diverter plates 232 are installed between the side blocks 231, and flow channels 233 are formed between the diverter plates 232.

[0033] As a preferred embodiment of this utility model, the kettle body 1 is a double-layer glass structure, with phase change heat storage material encapsulated in the interlayer.

[0034] As a preferred embodiment of this utility model, the phase change thermal storage material is paraffin wax.

[0035] As a preferred embodiment of this utility model, the stop block 227 and the rack 226 are an integrated structure.

[0036] In a preferred embodiment of this utility model, the height of the side block 231 is greater than that of the diverter plate 232.

[0037] As a preferred embodiment of the present invention, the top of the lid body 21 is provided with a connector 211, the top of the connector 211 is provided with an upper pull member 212, and the surface of the upper pull member 212 is provided with a pressing groove 213.

[0038] As a preferred embodiment of this utility model, the depth of the pressing groove 213 is adapted to the pressing arc of the finger.

[0039] The lid 2 is located on the top of the body 1 and includes the lid body 21 at the rear end and the flow limiting part 22 at the front end;

[0040] The lid body 21 has a connector 211 at the top, and the top of the connector 211 is connected to the pull-up piece 212. The pull-up piece 212 has a pressing groove 213 on its surface. The flow limiting part 22 includes a vertical through hole 221 and a horizontal slot 222. A gear 225 and a rack 226 are installed inside the slot 222. A rotating shaft 223 passes through the center of the gear 225. The rotating shaft 223 passes upward through the through hole 221 and is connected to a knob 224. A stop block 227 is fixed at the end of the rack 226. A baffle 228 is provided at the front end of the through hole 221. Side stops 231 are symmetrically arranged on the edge of the bottom surface 23 of the lid. Three flow dividers 232 are installed between the side stops 231. The gaps between the flow dividers 232 form four flow channels 233. The body 1 adopts a double-layer glass structure, and the interlayer is encapsulated with a phase change heat storage material, paraffin.

[0041] Multi-channel segmentation significantly reduces the kinetic energy of the coffee liquid, forcing it to change from turbulent to laminar flow, thus significantly reducing splashing and bubble generation during pouring. The narrow channel design increases the probability of physical obstruction of fine coffee grounds, effectively preventing residue from entering the spout with the liquid flow and affecting the taste. The four channels 233 are evenly distributed, allowing the coffee liquid to spread evenly to the flow-limiting section 22 through-hole 221 area, avoiding flow interruption caused by sudden changes in local flow velocity. It is suitable for scenarios requiring high-precision water injection, such as light roast coffee powder, and the laminar flow state ensures extraction uniformity.

[0042] Working principle: Before pouring coffee, the user presses the pressing groove 213 on the surface of the pull-up piece 212 above the lid body 21 with their finger to prevent the lid 2 from falling off; the coffee flows from the pot body 1 into the area of ​​the bottom surface 23 of the lid, where it is blocked from overflowing by the symmetrically arranged side baffles 231, and then is evenly guided to the flow limiting part 22 through the flow channels 233 formed by the gaps between the multiple flow dividers 232 after being divided; at this time, rotating the knob 224 drives the rotating shaft 223 to drive the gear 225 to rotate, and the meshing rack 226 moves horizontally. The stop 227 at the end of the rack 226 is linearly displaced, changing the area of ​​the stop 227 blocking the coffee liquid, thus achieving precise control of the coffee liquid flow rate; the baffle 228 covers the top of the rotating shaft 223 to prevent scalding; the pot body 1 adopts a double-layer glass structure, with paraffin phase change heat storage material encapsulated in the interlayer. When the coffee temperature is higher than the phase change point, it absorbs heat and melts; when the temperature drops, it solidifies and releases heat, significantly extending the heat preservation time; when standing, the pot lid 2 can be opened by the pull-up piece 212 for cleaning or brewing coffee. Example 2

[0043] like Figure 5 As shown, the difference between this embodiment 2 and embodiment 1 is that the three flow dividers 232 are replaced with two, thus forming three flow channels. Everything else remains the same.

[0044] The wide flow channel design significantly reduces the risk of fine residue clogging, making it especially suitable for high-residue scenarios such as dark roast coffee powder; improved flow adaptability: it can handle a larger flow rate per unit time to meet the needs of rapid brewing; ease of cleaning: the simplified flow channel structure with no narrow gaps significantly improves cleaning efficiency. Example 3

[0045] like Figure 6 As shown, the difference between this embodiment 3 and embodiment 1 is that: a longitudinal slide 24 is opened on the side wall of the flow limiting part 22, and the slide 24 longitudinally passes through the slot 222; a slide rod 241 is added, one end of which is fixedly connected to the rack 226, and the other end extends to the outside of the slide 24 and is provided with anti-slip ridges; the gear 225, the rotating shaft 223 and the knob 224 are removed, and the rest of the structure remains unchanged.

[0046] During operation, pulling the slide bar 241 will cause the rack 226 to move the stop block 227 horizontally.

[0047] The linear gliding mode is ergonomic, allowing for precise flow control with just one hand; left- or right-handed operation is greatly improved, eliminating the limitations of knob-based directional habits; the gear meshing structure has been eliminated to prevent mechanical jamming caused by coffee stain buildup.

[0048] In summary, this invention significantly improves the control accuracy and ease of operation of coffee pouring flow through the synergistic effect of the gear-rack transmission mechanism and the modular flow-dividing structure. The linear movement design of the knob-driven stop greatly optimizes the sensitivity of flow adjustment response, completely solving the problem of sudden flow changes in traditional spouts. The uniform flow channel formed by multiple flow dividers effectively suppresses coffee liquid turbulence, simultaneously preventing splashing and residue blockage. The composite protection system composed of side stops and baffles ensures leak-proof sealing while isolating the risk of burns from high-temperature components. The double-layered glass body combined with phase-change heat storage material utilizes the principle of latent heat circulation to significantly extend the coffee's constant temperature duration. The overall structure is compact and reasonable, achieving multiple technical advantages such as precise flow control, long-term heat preservation, and safety protection without increasing operational complexity.
