Description

Technical Field

[0001] This utility model relates to the technical field of beverage extraction and preparation equipment, specifically to a multi-purpose extraction handle. Background Technology

[0002] In the current beverage preparation industry, semi-automatic pressure coffee machines and other extraction devices are widely used in homes and commercial establishments. These devices typically require a portafilter to collect coffee grounds or tea leaves, which are then connected to the brewing head to extract the beverage using high-pressure hot water.

[0003] Traditional brewing handles often fail to provide sufficient pre-infusion during the initial extraction stage, meaning the powdered or tea leaves are not adequately moistened before extraction begins, affecting the consistency and quality of the final beverage. While some commercial equipment offers pre-infusion functionality, its complex structure and high cost make it difficult to implement in ordinary brewing handles.

[0004] Furthermore, current brewing portafilters on the market have some limitations: they are mainly categorized by capacity (single or double cup) and by structure (tea or coffee brewing). While these different types of portafilters can meet the brewing requirements of different users or different coffee varieties, the variety of portafilters increases the user's operating costs, and frequent portafilter switching also increases the workload of use and maintenance.

[0005] Therefore, there is an urgent need for a multi-purpose extraction handle that can adapt to various extraction needs, provide a stable pre-soaking function, and enable split output, in order to solve the above-mentioned problems in the existing technology. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a multi-purpose extraction handle that can adapt to various extraction needs, provide a stable pre-soaking function, and enable split-flow output.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A multi-purpose extraction handle includes an extraction body, a regulating valve body, and a diverter nozzle; the input end of the regulating valve body is connected to the output end of the extraction body, and the input end of the diverter nozzle is connected to the output end of the regulating valve body; a pressure driving unit is provided inside the regulating valve body, and the pressure driving unit is configured to open when the extraction liquid pressure reaches a threshold, so that the extraction liquid flows from the extraction body through the regulating valve body to the diverter nozzle.

[0008] Furthermore, a filter screen is provided inside the cavity of the extraction body, and the filter screen is fixed inside the cavity of the extraction body by fasteners.

[0009] Furthermore, the output end of the extraction body is connected to the input end of the regulating valve body by a thread, and a first sealing ring is provided at the connection.

[0010] Furthermore, the pressure driving unit includes a sealing gasket, a gasket cover, a spring, and a gasket; the gasket is horizontally disposed inside the regulating valve body, and has a through hole in its center; the spring is disposed above the gasket; the gasket cover is disposed above the spring; the sealing gasket is fixedly disposed above the gasket cover, and seals the output outlet of the extraction body under the action of the spring force.

[0011] Furthermore, the pressure drive unit also includes a connector, which is spirally connected to the inner side of the output end of the regulating valve body; the connector is provided with a blind hole corresponding to the central through hole of the gasket, and the inner sidewall of the blind hole is provided with a plurality of second diversion holes communicating with the output end of the regulating valve body.

[0012] Furthermore, the connector is provided with a pressure-reducing rubber ring, which is disposed around the second diversion hole of the connector.

[0013] Furthermore, the diverter nozzle is fastened to the output end of the regulating valve body, and a second sealing ring is provided at the connection.

[0014] Furthermore, the flow divider nozzle has an input flow channel and at least two output flow channels.

[0015] Furthermore, the lower part of the extraction body is provided with a first diversion hole, and a sealing gasket is connected to the lower part of the first diversion hole. The sealing gasket abuts against the first diversion hole to achieve a pressure-holding effect.

[0016] Furthermore, a pressure-reducing hole is provided at the lower edge of the connector, and a pressure-reducing rubber ring is provided on the outer surface of the pressure-reducing hole, and the pressure-reducing rubber ring is movably connected to the pressure-reducing hole.

[0017] Compared with existing technologies, the technical solution of this patent has the following advantages: 1. By integrating a pressure-driven unit into the regulating valve body, the extraction process is no longer a simple flow; instead, it waits for the extractant to accumulate within the extraction chamber and build up sufficient pressure before it can flow out. This ensures that the powder or tea leaves are fully pre-soaked and moistened during the initial extraction stage, significantly improving the stability and consistency of the extraction quality.

[0018] 2. By connecting the three components—the extraction body, the regulating valve, and the diverter—in series, this structure allows the single handle to be used for various beverages, including coffee and tea, and is compatible with multiple models, thus achieving the core purpose of multi-purpose use.

[0019] 3. By rotating the connector, the volume of the "cavity" formed between the through hole on the gasket and the blind hole of the connector can be adjusted, thereby changing the extraction flow rate and time to meet the extraction needs of different beverages.

[0020] 4. The diverter nozzle has one inlet channel and at least two outlet channels, which can simultaneously supply extract to two containers, ensuring a high degree of consistency in concentration, flavor and volume between the two beverages, and improving production efficiency.

[0025] 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.

[0026] See Figure 1-4As shown, this embodiment provides a multi-purpose extraction handle, including an extraction body 1, a regulating valve body 2, and a diverter nozzle 3. The input end of the regulating valve body 2 is connected to the output end of the extraction body 1, and the input end of the diverter nozzle 3 is connected to the output end of the regulating valve body 2. A pressure driving unit is provided inside the regulating valve body 2, which is configured to open when the extraction liquid pressure reaches a threshold, allowing the extraction liquid to flow from the extraction body 1 through the regulating valve body 2 to the diverter nozzle 3. Through the pressure driving unit integrated within the regulating valve body 2, the extraction process is no longer a simple flow; instead, it waits for the extraction liquid to accumulate in the cavity of the extraction body 1 and build up sufficient pressure before it can flow out. This ensures that the powder or tea leaves are fully pre-soaked and moistened during the initial extraction stage, significantly improving the stability and consistency of the extraction quality. Furthermore, this multi-purpose extraction handle, by connecting the extraction body 1, regulating valve body 2, and diverter nozzle 3 in series, allows a single handle to be used for various beverages, including coffee and tea, and is compatible with multiple machine models, achieving the core purpose of a multi-purpose handle.

[0027] A filter screen 6 is installed inside the cavity of the extraction body 1, and the filter screen 6 is fixed inside the cavity of the extraction body 1 by fasteners 7. The filter screen 6 is fixed inside the cavity by fasteners 7, such as screws or pressure plates, rather than being simply placed, ensuring that the filter screen 6 will not shift or fall off during repeated filling and rinsing, making the structure robust and reliable. At the same time, this detachable design allows users to easily remove the filter screen 6 for thorough cleaning, preventing cross-contamination of residues from different flavors and ensuring the pure flavor of the beverage.

[0028] The output end of the extraction body 1 is connected to the input end of the regulating valve body 2 via a thread, and a first sealing ring 4 is provided at the connection. The threaded connection provides strong mechanical connection force, and together with the first sealing ring 4, a reliable static seal is formed at the thread engagement point, completely preventing leakage of the extractant from the connection gap and ensuring stability. In addition, the threaded connection allows the user to manually separate the extraction body 1 from the regulating valve body 2, facilitating deep cleaning and maintenance of each component.

[0029] The pressure drive unit includes a sealing gasket 21, a gasket cover 22, a spring 23, and a washer 24. The gasket 24 is horizontally disposed inside the regulating valve body 2, with a through hole 241 in its center. The spring 23 is disposed above the gasket 24. The gasket cover 22 is disposed above the spring 23. The sealing gasket 21 is fixedly disposed above the gasket cover 22, sealing the outlet of the extraction body 1 under the action of the spring force. The preload force provided by the spring 23 sets the valve opening pressure threshold. When the extraction liquid pressure is insufficient to overcome the spring force, the sealing gasket 21 tightly seals the outlet under the transmission of the gasket cover 22, realizing the shut-off function. Once the pressure is sufficient, the liquid pressure pushes the sealing gasket 21 and the gasket cover 22 to compress the spring 23, opening the outlet of the extraction body 1.

[0030] The pressure-driven unit also includes a connector 25, which is spirally connected to the inner side of the output end of the regulating valve body 2. The connector 25 has a blind hole 251 corresponding to the central through hole 241 of the gasket 24. The inner wall of the blind hole 251 has several second diversion holes 252 that communicate with the output end of the regulating valve body 2. The spiral connection between the connector 25 and the valve body output end is a core design feature. Users can rotate the connector 25 with a tool such as a screwdriver to screw it in or out. This changes the volume of the "cavity" formed between the through hole 241 on the gasket 24 and the blind hole 251 of the connector. Screwing it in reduces the cavity size, allowing the liquid to fill faster and flow out from the second diversion holes 252, increasing the overall flow rate and resulting in a relatively lower output concentration. Screwing it out increases the cavity size, requiring more time for the liquid to fill, delaying the outflow time, extending the contact time between the powder / tea leaves and water, and resulting in a higher output concentration. The multiple second diversion holes 252 evenly distribute the liquid from the central blind hole 251 to the surrounding area, allowing it to smoothly enter the diversion nozzle 3.

[0031] Please read Figure 5-6 As shown, the lower part of the extraction body 1 is provided with a first diversion hole 11, and a sealing gasket 21 is connected to the lower part of the first diversion hole 11. The sealing gasket 21 abuts against the first diversion hole 11 to achieve a pressure-holding function. That is to say, when the water pressure of the extraction body 1 is too high, the water pressure pushes open the sealing gasket 21 to allow the liquid to flow downward.

[0032] The lower edge of the connector 25 is provided with a pressure-reducing hole 253, and a pressure-reducing rubber ring 26 is provided on the outer surface of the pressure-reducing hole 253. The pressure-reducing rubber ring 26 is movably connected to the pressure-reducing hole 253. By setting the pressure-reducing rubber ring 26, the water flow can be prevented from being too large, that is, it will not spray directly, thus avoiding excessive pressure and outward spraying.

[0033] The connector 25 is equipped with a pressure-reducing rubber ring 26, which is made of silicone. The pressure-reducing rubber ring 26 is installed around the second diversion hole 252 of the connector 25. It mainly activates the secondary pressure reduction function and uses the elasticity of silicone itself to balance the pressure reduction under different pressures, so as to prevent boiling water from splashing onto people when the water pump pressure is too high.

[0034] The diverter nozzle 3 is snap-fitted to the output end of the regulating valve body 2, and a second sealing ring 5 is provided at the connection. The snap-fit ​​connection, such as a snap-fit ​​or quick-connect structure, allows users to quickly install or replace different styles of diverter nozzles without using tools. The second sealing ring 5 ensures the reliability of the seal under the quick-disassembly structure, preventing leakage after extraction or improper installation, and keeping the working area clean.

[0035] The spout 3 has an inlet channel 31 and at least two outlet channels 32. By providing at least two outlet channels 32, the handle can simultaneously supply extract to two containers, such as two coffee cups. This not only improves production efficiency but, more importantly, ensures a high degree of consistency in concentration, flavor, and volume between the two beverages, avoiding potential differences caused by sequential extraction. This is particularly suitable for business settings or when entertaining multiple guests at the same time.

[0036] The working principle of this multi-purpose extraction handle is as follows: After the extractant is filled to a certain volume in the extraction body 1 and pressure is generated, the extractant pushes open the sealing gasket 21, causing the sealing gasket 21 and the gasket cover 22 to move downwards. The extractant flows into the regulating valve body 2 through the output end of the extraction body 1. The extractant enters the blind hole 251 of the connector 25 along the central through hole 241 of the gasket 24. When the blind hole 251 reaches a certain volume, the extractant flows out from the second diversion hole 252 on the inner side wall of the blind hole 251. After flowing out through the second diversion hole 252, the extractant enters the input channel 31 of the diversion nozzle 3 and is output to the container through the output channel 32. When there is no extractant in the extraction body 1 or the extractant has not reached a certain volume to generate pressure, the sealing gasket 21 and the gasket cover 22 move upwards under the force of the spring 23, so that the sealing gasket 21 remains sealed with the output end outlet of the extraction body 1.
