Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, specifically to a liquid diversion device for coffee extraction. Background Technology

[0002] A diverter in coffee extraction is a tool used to optimize the extraction process and improve coffee quality. Its main function is to rationally distribute and control the water or coffee liquid during extraction. Common diverters include diverter filters, diverter pourers, and diverter portafilters. Diverters are key tools for achieving "uniform extraction" in coffee brewing. Through physical structural design, they optimize water flow distribution, allowing for more even contact between coffee grounds and water, thereby improving the flavor and quality of the final beverage. Whether it's pour-over or espresso, the proper selection and use of a diverter can help baristas (or enthusiasts) better control the extraction process and unleash the coffee's optimal flavor potential.

[0003] Existing coffee handpieces typically employ a fixed design, making it difficult to precisely control liquid flow. This hinders adaptation to the varying water flow requirements of different coffee bean varieties and extraction processes (such as pour-over and espresso), resulting in either insufficient or over-extraction of coffee flavors and negatively impacting the final beverage's taste. Furthermore, the fixed handpiece design of traditional devices prevents flexible adjustment of the operating distance based on container size and brewing head height during coffee grounds or liquid dispensing. When using smaller containers, a short handpiece can cause inconvenience, difficulty in dispensing coffee grounds, and even spillage. Additionally, the non-adjustable handpiece poses a safety hazard when near hot steam or liquids, increasing the risk of burns. Utility Model Content

[0004] To address the problems of uncontrollable flow rate and unadjustable support length, the purpose of this invention is to provide a liquid diversion device for coffee extraction.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a liquid diversion device for coffee extraction, comprising a hopper, a flow control device fixedly installed at the lower end of the hopper, a telescopic handle rotatably connected to one side of the hopper, a through-type liquid outlet groove opened inside the hopper, a filter screen sleeved on the upper surface of the hopper, a liquid distributor fixedly connected to the lower surface of the flow control device, the telescopic handle comprising a knob and a lower housing, a rotating rod fixedly connected to one end of the knob, an upper housing threadedly connected to one end of the lower housing, a guide groove opened on the outer surface of the upper housing, a sliding pin fixedly connected to the outer surface of the rotating rod, a telescopic rod fixedly connected to one end of the rotating rod, and the rotating rod and the telescopic rod respectively penetrating the upper housing and the lower housing.

[0006] Preferably, the flow control device includes a main body, an inlet on the upper surface of the main body, an outlet on the lower surface of the main body, the inlet and outlet communicating with each other, an outlet groove communicating with the inlet, a threaded rod threaded into one side of the main body, a handwheel fixedly sleeved at one end of the threaded rod, and a valve core fixedly connected to the other end of the threaded rod, the valve core being located inside the main body.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] This invention incorporates a flow control device and a telescopic handle. The flow control device utilizes a threaded transmission structure, with a handwheel rotating to drive the valve core for precise displacement, thus regulating the flow rate to suit different coffee extraction needs. Simultaneously, its modular threaded connection design facilitates quick disassembly and cleaning, ensuring a clean flow path. The telescopic handle uses a spiral guide groove and a sliding pin to convert rotary rotation into axial extension and retraction of the telescopic rod.

[0015] 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.

[0016] Example: Figure 1-3 As shown, this utility model provides a liquid diversion device for coffee extraction. The device includes a cone-shaped hopper 11 with a flow control device 12 fixed at its lower end and a telescopic handle 13 rotatably connected to one side. An internal through-type liquid outlet trough 16 is formed, and a filter screen 15 is fitted onto its upper surface. The filter screen 15 is made of rubber, with multiple filter holes arranged in a ring array on its outer surface. Its edges are embedded in an annular groove 14 on the inner surface of the hopper 11. Through elastic sealing, coffee grounds are intercepted, allowing liquid to only permeate through the filter holes into the liquid outlet trough 16, achieving initial solid-liquid separation and ensuring the purity of the subsequent liquid diversion.

[0017] The flow control device 12 includes a main body 27, with an inlet 28 on its upper surface communicating with the outlet tank 16 and an outlet 29 on its lower surface communicating with the distributor 17. A threaded rod 30 is threaded into one side, with one end of the threaded rod 30 fixedly connected to a handwheel 31 and the other end extending into the main body 27 and fixedly connected to a valve core 32. The outer surface of the upper end of the main body 27 has an external thread, forming a detachable threaded connection with the internal thread on the inner surface of the outlet tank 16. In use, rotating the handwheel 31 drives the threaded rod 30 to move axially, using the thread lead to convert the circumferential motion into a linear displacement of the valve core 32, thereby achieving precise adjustment of the opening degree of the inlet 28 and controlling the liquid flow rate to meet different extraction requirements.

[0018] The telescopic handle 13 includes a knob 19 and a lower housing 22. One end of the knob 19 is fixedly connected to a rotating rod 20, and one end of the lower housing 22 is threadedly connected to an upper housing 23. A spiral guide groove 24 is formed on the outer surface of the upper housing 23. A sliding pin 21, which slides and fits in contact with the guide groove 24, is fixedly connected to the outer surface of the rotating rod 20. A telescopic rod 25 is fixedly connected to one end of the rotating rod 20, and a spring 26 is sleeved on its outer surface. The two ends of the spring 26 abut against the inner wall of the lower housing 22 and the end face of the telescopic rod 25, respectively. A limiting groove for use with the sliding pin 21 is formed at one end of the guide groove 24. The outer surface of the knob 19 is provided with anti-slip texture. During operation, rotating the knob 19 drives the rotating rod 20 to rotate, causing the sliding pin 21 to slide along the guide groove 24, converting the circular motion into the axial extension and retraction of the telescopic rod 25. The spring 26 provides cushioning and locks the position through the abutment of the limiting groove and the sliding pin 21, realizing the rapid adjustment of the handle length to adapt to different operating scenarios.

[0019] Two arc-shaped dispensing ports 18 are symmetrically arranged on the outer surface of the dispensing device 17. The arc angle of the dispensing ports 18 is 45°-60°. Through the principle of fluid dynamics, the liquid flows out and forms a tangential velocity component, which is dispersed into a fan-shaped surface to ensure that the coffee powder layer is evenly moistened, improve the extraction efficiency, and achieve efficient and stable coffee extraction liquid dispensing.

[0020] Working principle: When this coffee extraction liquid diversion device is working, the user first pours the ground coffee powder into the filter bag 15 inside the hopper 11. The edge of the rubber filter bag 15 is embedded in the annular groove 14 on the inner wall of the hopper 11 to achieve a seal and prevent coffee grounds from leaking out. After hot water is injected from above the hopper 11, the liquid formed by dissolving the coffee powder is collected at the bottom of the hopper 11 through the filter holes of the filter bag 15, and flows into the inlet 28 inside the main body 27 of the flow control device 12 through the liquid outlet 16. The inlet 28 and the outlet 29 together form a flow channel. When the flow rate needs to be adjusted, the handwheel 31 is turned, which drives the valve core 32 to move axially through the threaded rod 30, changing the opening of the valve core 32 and the flow channel, thereby achieving precise control of the liquid flow rate.

[0021] The adjusted liquid enters the distributor 17 through the outlet 29 at the bottom of the main body 27, and flows out to both sides through the symmetrically distributed arc-shaped distributor ports 18 at its bottom. During operation, if it is necessary to adjust the length of the telescopic handle 13, the knob 19 can be turned to rotate the rotating rod 20, causing the sliding pin 21 fixed on the rotating rod 20 to slide along the spiral guide groove 24 of the upper housing 23. The spiral trajectory of the guide groove 24 forces the rotating rod 20 to produce axial displacement, thereby causing the telescopic rod 25 to extend or retract, realizing the adjustment of the length of the telescopic handle 13. The spring 26 provides buffering and maintains positional stability during the extension and retraction process. The limiting groove at the end of the guide groove 24 helps the sliding pin 21 to abut against the limiting groove through the reaction force of the spring 26 when it rotates to the end of the guide groove 24, thus limiting and locking the rotating rod 20. The entire device is modularly assembled via threaded connections, such as the main body 27 and the liquid outlet tank 16, which facilitates disassembly and cleaning. Through the coordinated work of the above components, it integrates functions such as filtration, flow control, liquid dispensing, and handle extension and retraction, providing an efficient and controllable solution for coffee extraction.

[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
