Description

TECHNICAL FIELD

[0001] The utility model relates to a cup with brewing function. BACKGROUND

[0002] As a popular beverage all over the world, the convenient brewing method of coffee has always been the focus of industry research and consumer attention. In recent years, the market demand for portable coffee brewing equipment has been growing, especially the brewing device using coffee capsules, which is favored by consumers because of its simple operation and fast brewing speed. Currently, some brewing devices on the market are designed as cup cover structures, which can be directly used with coffee cups to improve portability and applicability. However, the existing portable coffee brewing device still has certain limitations and deficiencies in use, mainly in the following aspects:

[0003] The existing cup cover type coffee brewing device usually adopts a bottom extraction chamber design, and the user needs to install the coffee capsule into the extraction chamber first, and then invert the coffee cup to make the water enter the extraction chamber for extraction. The operation process is relatively complex, and the inversion operation is not intuitive, which brings inconvenience to the user, especially when used in mobile scenarios or outdoor environments, which affects the brewing experience.

[0004] In the prior art, the coffee capsule directly contacts water in the extraction chamber, and due to the difficulty in precisely controlling the water flow direction and flow rate, the extraction efficiency of water when passing through the coffee powder is not high, which easily causes insufficient extraction or over-extraction, thereby affecting the taste of coffee. In addition, the coffee liquid flows directly into the cup body, lacking a secondary diffusion mechanism, resulting in uneven release of coffee flavor and affecting the overall drinking experience.

[0005] Since the extraction chamber of the existing device is located at the bottom of the equipment, coffee residue is easily left after brewing, and the cleaning process is relatively cumbersome. If not cleaned thoroughly, long-term use may cause hygiene hazards. In addition, in some designs, the extraction chamber and the sealing structure are complex, further increasing the difficulty of disassembly and cleaning. INVENTION CONTENTS

[0006] The utility model aims at providing a cup with brewing function that improves the uniformity and efficiency of coffee extraction, improves the uniformity of coffee flavor, and further improves the brewing quality.

[0007] The utility model achieves the purpose as follows:

[0008] A cup with brewing function, comprising a cup cover, a cup body, and a brewing effect enhancement module, the cup cover is built-in with a water booster, the cup cover is provided with an extraction chamber, the top of the extraction chamber is open to form an open mouth, and the bottom of the extraction chamber is provided with an extraction liquid outlet;

[0009] The cup cover is provided with a liquid inlet, the inlet of the water pressurizing device is communicated with the liquid inlet, and the outlet of the water pressurizing device is communicated with the extraction cavity.

[0010] The brewing effect enhancing module comprises a liquid discharging pipe and a horn-shaped cover body, the horn-shaped cover body is provided with an opening, the upper end of the liquid discharging pipe is communicated with the extraction liquid outlet, the horn-shaped cover body is arranged at the lower end of the liquid inlet pipe, and the lower end of the liquid discharging pipe is communicated with the opening.

[0011] The cup cover is detachably arranged on the cup body, and the gap between the horn-shaped cover body and the inner cavity of the cup body forms an extraction liquid diffusion area.

[0012] Since the coffee liquid is blocked and diffused slowly when passing through the horn-shaped cover body, the water pressurizing device mainly extracts pure water through the liquid inlet, so that the coffee liquid is avoided to be extracted, and thus the liquid entering the extraction cavity is pure water.

[0013] The pure water entering the extraction cavity is mixed with the concentrated coffee liquid in the coffee capsule, and since the solubility of the pure water is high, the coffee components can be better dissolved, so that the coffee liquid with more optimal concentration and better flavor is formed.

[0014] The extraction liquid diffuses to the cup body through the horn-shaped cover body, and a uniform diffusion area is formed in the cup body, so that the overall extraction effect of the coffee liquid is more balanced, and the taste is more coordinated.

[0015] If the user selects a longer brewing time, the coffee liquid has been completely diffused to the whole cup body, at this time, the water pressurizing device continues to extract the coffee liquid to the extraction cavity through the liquid inlet, and continues to promote the dissolution of the concentrated coffee liquid in the coffee capsule in the coffee liquid, so that the coffee liquid with more optimal concentration and richer taste is finally obtained.

[0016] The cup cover is detachably connected with the cup body, so that the user can conveniently clean and maintain after use, and meanwhile, the coffee residues are avoided to be mixed into the water pressurizing device, and the hygiene and the service life of the equipment are improved.

[0017] The technical measures can also be used to solve the problems.

[0018] Further, the extraction liquid diffusion and slowing module is a horn-shaped cover body or a flat cover body.

[0019] Further, the horn-shaped cover body comprises at least two arc-shaped flow guide pieces, the front end of the arc-shaped flow guide piece is connected with the outer wall of the lower end of the liquid discharging pipe, the rear end of the arc-shaped flow guide piece extends outward, and the arc-shaped flow guide piece is inclined from the front end to the rear end.

[0020] By setting at least two arc-shaped guide vanes on the trumpet-shaped cover, with their front ends connected to the outer wall of the lower port of the drain pipe and their rear ends extending outward and tilting from front to back, the flow direction and speed of the extracted coffee liquid can be effectively guided and adjusted, preventing the coffee liquid from spreading too quickly, thereby improving the uniformity of coffee extraction and the stability of flavor.

[0021] Furthermore, a first extract diffusion region is formed between the arc-shaped guide vanes and the arc-shaped guide vanes.

[0022] The smaller diffusion area of ​​the first extract formed between the arc-shaped guide vanes significantly slows down the diffusion rate of the coffee liquid. This design ensures that the water pressurization device primarily draws pure water when passing through the inlet, thus keeping the liquid entering the extraction chamber pure water. This promotes better dissolution of the concentrated coffee in the coffee capsule in pure water, ultimately resulting in a coffee liquid with a higher concentration and richer flavor.

[0023] If the user selects a longer brewing time, the coffee liquid has completely diffused throughout the cup. At this time, the water pressurization device continues to draw coffee liquid into the extraction chamber through the inlet, which continues to promote the dissolution of the concentrated coffee liquid in the coffee capsule in the coffee liquid, and finally obtains a coffee liquid with better concentration and richer taste.

[0024] Furthermore, there are three arc-shaped guide vanes.

[0025] The use of three arc-shaped guide vanes achieves a symmetrical and balanced flow effect, allowing the coffee liquid to spread evenly in multiple directions. This symmetrical layout not only further optimizes the diffusion path of the coffee liquid but also provides more stable control over its flow, improving the overall stability of the brewing process and the extraction effect.

[0026] Furthermore, the horn-shaped cover and the cup are tightly fitted together, and the gap between the horn-shaped cover and the cup forms a second extract diffusion area.

[0027] The tight fit between the trumpet-shaped cover and the cup body creates a small secondary extraction diffusion zone between them, further slowing down the diffusion rate of the coffee liquid. This ensures that the water pressurization device draws primarily pure water from the inlet, preventing the mixing of coffee liquid. This guarantees that the liquid entering the extraction chamber is always pure water, maximizing the optimal mixing of pure water and concentrated coffee liquid, thus achieving a more ideal coffee extraction concentration and flavor.

[0028] If the user selects a longer brewing time, the coffee liquid has completely diffused throughout the cup. At this time, the water pressurization device continues to draw coffee liquid into the extraction chamber through the inlet, which continues to promote the dissolution of the concentrated coffee liquid in the coffee capsule in the coffee liquid, and finally obtains a coffee liquid with better concentration and richer taste.

[0029] Furthermore, the top of the cup lid is provided with a flip cover for closing or opening the extraction chamber. The flip cover is provided with an upper piercing needle tube. One end of the upper piercing needle tube forms a first spike, which faces the extraction chamber. The other end of the upper piercing needle tube is connected to the outlet of the water pressurization device.

[0030] The flip-top design allows users to quickly open or close the extraction chamber when needed, enhancing the equipment's sealing performance and ease of cleaning and maintenance.

[0031] The design of the upper piercing needle tube, with its first piercing point facing the extraction chamber, can accurately pierce the coffee capsule or create a liquid passage when the lid is closed, ensuring efficient water output from the water pressurization device and allowing pure water to smoothly enter the extraction chamber, thereby improving extraction efficiency and coffee flavor.

[0032] Furthermore, a piercing needle tube is provided at the bottom of the extraction chamber, with the second tip of the piercing needle tube facing the extraction chamber, and the other end of the piercing needle tube forming the extract outlet.

[0033] The bottom of the extraction chamber is equipped with a needle tube, whose second spike ensures that the coffee liquid can be smoothly discharged after extraction, forming a stable liquid outlet.

[0034] This design helps maintain fluid balance during the extraction process, allowing the coffee liquid to be evenly discharged and enter the subsequent diffusion area, further improving the brewing effect and beverage quality.

[0035] Furthermore, it also includes a control module and a battery, which are mounted on the cup lid. The water pressurization device and the battery are electrically connected to the control module. The battery supplies power to the water pressurization module and the control module. The control module controls the start and stop of the water pressurization device, which is a water pump.

[0036] The control module and battery are integrated into the cup lid, making the entire brewing system more compact, portable, and easy to operate.

[0037] The battery powers the water booster (as a water pump) and the control module, ensuring stable operation of the system without external power. Meanwhile, the control module can precisely control the start and stop of the water pump, enabling timely regulation of the water flow, thereby optimizing the extraction process and improving energy efficiency.

[0038] Furthermore, the inner wall of the top of the cup body is provided with an internal thread, and the outer wall of the cup lid is provided with an external thread. The external thread and the internal thread engage to connect the cup lid and the cup body.

[0039] The inner wall of the cup body is provided with an internal thread that engages with the external thread on the outer wall of the cup lid, which can effectively achieve a firm connection between the cup lid and the cup body, ensure sealing, and prevent liquid leakage.

[0040] This design not only enhances the stability of the overall structure, but also facilitates quick disassembly and assembly by users, and makes cleaning and maintenance easier, thereby improving the product's lifespan and hygiene safety.

[0041] Furthermore, the cup lid is provided with a liquid outlet channel that runs vertically through the cup, and the upper end of the liquid outlet channel extends out of the top of the cup lid to form a suction port, which is provided with a removable plug.

[0042] The lid features a continuous flow channel, allowing brewed coffee to be dispensed directly from the sippy port at the top of the lid or consumed by the user, simplifying the process.

[0043] The suction port is equipped with a removable cap, which effectively prevents liquid leakage or contamination when not in use. It also allows users to open or close the cap as needed, further enhancing convenience and safety.

[0044] The beneficial effects of this utility model are as follows:

[0045] In this invention, the coffee liquid is blocked and its diffusion is slowed when it passes through the funnel-shaped cover. The water pressurization device mainly draws pure water through the inlet, avoiding the extraction of coffee liquid. This ensures that the liquid entering the extraction chamber is pure water. The use of pure water in the extraction chamber allows the concentrated coffee liquid in the coffee capsule to be fully mixed with the pure water. Since pure water has a high solubility, it can better dissolve coffee components, thus forming a coffee liquid with better concentration and flavor.

[0046] In this invention, the first extraction liquid diffusion area formed between the arc-shaped guide vanes is relatively small, which can significantly slow down the diffusion rate of the coffee liquid. This design ensures that the water pressurization device mainly draws pure water when passing through the inlet, thereby keeping the liquid entering the extraction chamber as pure water. This promotes better dissolution of the concentrated coffee liquid in the coffee capsule in pure water, ultimately resulting in a coffee liquid with a higher concentration and a richer flavor.

[0047] This invention, through the tight fit between the trumpet-shaped cover and the cup body, creates a small secondary extraction liquid diffusion area between them, further slowing down the diffusion rate of the coffee liquid. This ensures that the water pressurization device draws primarily pure water from the inlet, preventing the mixing of coffee liquid. This guarantees that the liquid entering the extraction chamber is always pure water, fully utilizing the optimal mixing effect of pure water and concentrated coffee liquid, thereby achieving a more ideal coffee extraction concentration and flavor.

[0048] In this invention, if the user selects a longer brewing time, the coffee liquid has completely diffused throughout the entire cup. At this time, the water pressurization device continues to draw coffee liquid into the extraction chamber through the liquid inlet, which continues to promote the dissolution of the concentrated coffee liquid in the coffee capsule in the coffee liquid, and finally obtains a coffee liquid with better concentration and richer taste.

[0061] Furthermore, a first extract diffusion region 62 is formed between the arc-shaped guide vane 61 and the arc-shaped guide vane 61.

[0062] Furthermore, the arc-shaped guide vane 61 has three pieces.

[0063] Furthermore, the trumpet-shaped cover 6 and the cup body 2 are tightly fitted together, and the gap between the trumpet-shaped cover 6 and the cup body 2 forms a second extract diffusion region 63.

[0064] Furthermore, the top of the cup lid 1 is provided with a flip cover 7 for closing or opening the extraction chamber 4. The flip cover 7 is provided with an upper piercing needle tube 71. One end of the upper piercing needle tube 71 forms a first piercing opening 711, which faces the extraction chamber 4.

[0069] User's coffee brewing process using coffee capsules

[0070] First, the user adds pure water to the cup body 2, and then installs the cup lid 1;

[0071] Next, the coffee capsule 10 is correctly placed into the extraction chamber 4, and then the flip cover 7 is closed. The first sharp point 711 of the upper needle tube 71 on the flip cover 7 will face and pierce the coffee capsule 10. At the same time, the second sharp point 411 of the lower needle tube 41 at the bottom of the extraction chamber 4 also pierces the bottom of the coffee capsule 10.

[0072] Next, the user presses the start button on the control module, and the control module uses the battery to power the water booster device 3 (water pump) and start working.

[0073] Next, the water pump draws pure water through the inlet 11 and delivers it to the extraction chamber 4 at a stable pressure. After entering the extraction chamber 4, the pure water comes into contact with the concentrated coffee liquid in the coffee capsule 10, so that the coffee components are fully dissolved in the pure water to form coffee liquid of ideal concentration.

[0074] Next, the extracted coffee liquid flows into the funnel-shaped cover 6 through the drain pipe 5 and gradually diffuses into the inside of the cup body 2. During this process, the arc-shaped guide plate 61 and the first extraction liquid diffusion area 62 formed therein, as well as the second extraction liquid diffusion area 63 between the cup body 2 and the funnel-shaped cover 6, work together to effectively slow down the diffusion speed of the coffee liquid, thereby ensuring that the water pressurization device 3 mainly extracts pure water.

[0075] Finally, users do not need to remove the cup lid 1; they can drink coffee directly through the sip 14. The sip 14 is equipped with a removable cap 9, which helps to maintain the hygiene of the liquid and prevent spills when not in use.

[0076] The principle behind excellent coffee extraction results

[0077] The control module precisely controls the water flow and pressure, allowing pure water to enter the extraction chamber 4 at an appropriate pressure and fully contact the concentrated coffee liquid in the coffee capsule 10 for extraction.

[0078] In addition, a multi-diffusion control mechanism was designed, such as the arc-shaped guide plate 61, the first extraction liquid diffusion area 62, and the second extraction liquid diffusion area 63, which effectively slows down the diffusion speed of the coffee liquid, ensures that the water pressurization device 3 mainly extracts pure water, thereby improving the extraction effect and maintaining the uniform concentration and stable flavor of the coffee liquid.

[0079] If the user selects a longer brewing time, the coffee liquid has completely diffused throughout the entire cup body 2. At this time, the water pressurization device 3 continues to draw coffee liquid into the extraction chamber 4 through the liquid inlet 11, which continues to promote the dissolution of the concentrated coffee liquid in the coffee capsule 10 in the coffee liquid, and finally obtains a coffee liquid with better concentration and richer taste.

[0080] In this embodiment, the extraction chamber 4 can hold a coffee capsule 10 or coffee powder. In other embodiments, the extraction chamber 4 can also hold tea leaves, etc.
