Description

Technical Field

[0001] This utility model relates to coffee cups, and more particularly to a cold brew coffee cup. Background Technology

[0002] With the continuous development of coffee brewing technology, patent application number 201811555536.4 discloses a cold brewing device and a method for cold brewing coffee. This technical solution involves setting up a cold brewing chamber for holding water and a coffee powder chamber for holding coffee, with their bottoms connected by a connecting piece. An air pump connected to the upper side wall of the coffee powder chamber uses negative pressure suction and reverse pressurization to achieve repeated flow of water between the two containers to brew coffee, increasing the extraction speed and improving cold brewing efficiency. At the same time, the components are easy to disassemble and clean, thus solving some of the problems of traditional coffee brewing technology to a certain extent.

[0003] However, current coffee brewing techniques still have many shortcomings. Traditional hot water brewing breaks down the tannins in coffee, severely impacting the taste and making it difficult to bring out the original flavor and purity of the coffee. While cold water immersion extraction avoids tannin breakdown, the common static extraction method is less efficient, and the coffee grounds and liquid are mixed after extraction, requiring filtering before drinking, a cumbersome process.

[0004] Even the technology with application number 201811555536.4 has certain limitations in practical applications. On the one hand, the device has a relatively complex structure, and the connection and coordinated operation of multiple components increases the probability of failure and makes maintenance and repair more difficult. On the other hand, it is not portable, which is not conducive to consumers using it when going out or traveling.

[0005] As consumers increasingly demand higher quality and greater convenience in coffee brewing, existing coffee brewing equipment and methods are no longer sufficient to meet market needs. Against this backdrop, a novel cold brew cup solution has emerged, aiming to overcome the shortcomings of current technology and provide consumers with a more efficient, convenient, and high-quality cold brew experience. Utility Model Content

[0006] This invention addresses the shortcomings of existing technologies by providing a cold brew coffee cup.

[0007] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0008] A cold brew coffee cup, comprising:

[0009] The cup body is used to hold purified water.

[0010] The cold brew compartment is located inside the glass and is used to hold ice cubes.

[0011] The coffee powder container is located inside the cup and is connected to the lower end of the cold brew container. An upper filter screen is installed between the cold brew container and the coffee powder container. The coffee powder container has a through hole that connects to the cup body, and a lower filter screen is installed on the through hole. The coffee powder container is used to hold coffee powder.

[0012] The first air pump is installed inside the cup and is connected to the cold extraction chamber. The first air pump is used to extract gas from the cold extraction chamber.

[0013] The second air pump is installed inside the cup and is connected to the cold extraction chamber. The second air pump is used to introduce gas into the cold extraction chamber.

[0014] Preferably, the coffee powder compartment and the cold brew compartment are detachably connected.

[0015] As a preferred option, a first sealing ring is installed between the coffee powder compartment and the cold brew compartment.

[0016] Preferably, an organic core shell is installed at the upper end of the cup body, and both the first and second air pumps are installed in the organic core shell; the organic core shell is detachably connected to the cold extraction chamber.

[0017] Preferably, a second sealing ring is installed between the movement housing and the cold extraction chamber.

[0018] Preferably, the core housing is equipped with a main pipe that communicates with the cold extraction chamber. The first air pump is equipped with a first branch pipe and a second branch pipe at its two ends. The other end of the first branch pipe is connected to the main pipe, and the other end of the second branch pipe is connected to the outside. One end of the second air pump is connected to the second branch pipe, and the other end of the second air pump is connected to the main pipe.

[0019] Preferably, a first water level sensor is installed on the core housing, extending into the cold extraction chamber.

[0020] Preferably, a second water level sensor is installed on the housing of the mechanism, extending into the cup body.

[0023] This utility model, by adopting the above technical solution, has significant technical effects:

[0024] (1) The first air pump draws gas from the cold brew chamber, which creates a negative pressure in the cold brew chamber, causing water in the cup to flow quickly into the coffee powder container and come into full contact with the coffee powder before entering the cold brew chamber; the second air pump inflates the cold brew chamber, which increases the air pressure in the cold brew chamber and forces the coffee powder in the cold brew chamber and coffee powder container back into the cup. This cycle accelerates the coffee extraction process, improves cold brew efficiency, and significantly shortens the production time compared to traditional static cold brew.

[0025] (2) The upper and lower filter screens effectively prevent coffee powder from entering the cold brew chamber and the cup, ensuring the purity of the coffee liquid, avoiding residue from affecting the taste, fully preserving the flavor and taste of the coffee, and improving the quality of the coffee.

[0026] (3) The entire cold extraction process can be completed by the air pumping and air filling operations of two air pumps. The operation is simple and convenient, without complicated steps, which lowers the threshold for use and is suitable for different groups of people.

[0027] (4) The cup body, cold brew chamber, coffee powder chamber and air pump are designed to be relatively independent and easy to disassemble. After use, each part can be thoroughly cleaned to keep the equipment clean and hygienic, reduce bacterial growth and ensure the safety of the beverage. Attached Figure Description

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described in detail with reference to the embodiments.

[0035] Example 1

[0036] A cold brew coffee cup, comprising:

[0037] Cup body 10, cup body 10 is used to hold purified water;

[0038] Cold brew chamber 11 is located inside the cup body 10 and is used to hold ice cubes;

[0039] The coffee powder compartment 12 is located inside the cup body 10 and communicates with the lower end of the cold brew compartment 11. An upper filter 13 is provided between the cold brew compartment 11 and the coffee powder compartment 12. The coffee powder compartment 12 presses against the upper filter 13, thereby securing it to the lower end face of the cold brew compartment 11. The upper filter 13 prevents coffee powder from entering the cold brew compartment 11 and facilitates water entry into the cold brew compartment 11. The coffee powder compartment 12 has a through hole 121 communicating with the cup body 10. A lower filter 14 is installed on the through hole 121. The coffee powder compartment 12 is used to hold coffee powder. The lower filter 14 prevents coffee powder from entering the cup body 10 and facilitates water from the cup body 10 to enter the coffee powder compartment 12.

[0040] The first air pump 15 is an electric air pump, which uses an electric motor as a drive source. The first air pump 15 is installed inside the cup body 10 and is connected to the cold brew chamber 11 through a pipeline. The first air pump 15 is used to extract gas from the cold brew chamber 11. When the first air pump 15 is started, the water in the cup body 10 enters the cold brew chamber 11 through the coffee powder compartment 12 and rises to the set position.

[0041] The second air pump 16 is an electric air pump that uses a motor as a drive source. The second air pump 16 is installed inside the cup body 10 and is connected to the cold brew chamber 11 through a pipeline. The second air pump 16 is used to introduce gas into the cold brew chamber 11. When the second air pump 16 is started, the first air pump 15 stops, the air pressure in the cold brew chamber 11 increases, and the coffee in the cold brew chamber 11 and the coffee powder chamber 12 is pushed back into the cup body 10.

[0042] When the cold brew coffee cup is in operation, the first air pump 15 and the second air pump 16 operate alternately. The cup body 10 contains purified water, the cold brew chamber 11 contains ice cubes, and the coffee powder chamber 12 contains coffee powder. First, the first air pump 15 starts, drawing gas from the cold brew chamber 11. This causes the water in the cup body 10 to be drawn into the coffee powder chamber 12 through the through-hole 121 and the lower filter 14 under the pressure difference, and then through the upper filter 13 into the cold brew chamber 11, rising to the set position. At this point, the first air pump 15 stops, and the second air pump 16 starts, filling the cold brew chamber 11 with gas, pressing the coffee powder in the cold brew chamber and coffee powder chamber back into the cup body. This cycle continues, completing the cold brew process.

[0043] By setting the first air pump 15 and the second air pump 16 to work alternately, the flow of water between the cold brew chamber 11 and the coffee powder chamber 12 can be effectively controlled, automating the cold brewing process and eliminating the need for manual water pouring, making it more convenient. Meanwhile, the upper filter 13 and the lower filter 14 prevent coffee powder from entering other containers during the cold brewing process, ensuring the purity of the coffee liquid; on the other hand, they allow water to flow smoothly, ensuring the smooth progress of the cold brewing process. Furthermore, the ingenious design of each component, such as the connection and installation method of the cold brew chamber 11 and the coffee powder chamber 12 within the cup body 10, makes the entire cold brew cup structure compact and reasonable, easy to carry and use.

[0044] The coffee powder compartment 12 and the cold brew compartment 11 are detachably connected. The coffee powder compartment 12 and the cold brew compartment 11 are connected by threads. The coffee powder compartment 12 is easy to disassemble and assemble, making it convenient for users to clean the coffee powder compartment 12 and put in coffee powder.

[0045] A first sealing ring 17 is installed between the coffee powder compartment 12 and the cold brew compartment 11. The first sealing ring 17 between the cold brew compartment 11 and the coffee powder compartment 12 greatly enhances the sealing performance, preventing water and air leakage during cold brewing, thus avoiding affecting the cold brewing effect and causing inconvenience in use.

[0046] An internal housing 18 is installed at the upper end of the cup body 10. The first air pump 15 and the second air pump 16 are both installed in the internal housing 18. The internal housing 18 is detachably connected to the cold extraction chamber 11, which is threadedly connected to the internal housing 18. The internal housing 18 is used to install the first air pump 15 and the second air pump 16, and also serves to isolate water. Installing the first air pump 15 and the second air pump 16 within the internal housing 18 at the upper end of the cup body 10 results in a more rational layout, effectively utilizing space, avoiding direct contact between the air pumps and water, and extending the service life of the air pumps. The detachable threaded connection between the internal housing 18 and the cold extraction chamber 11 allows users to easily disassemble and clean the components after use, maintaining the cleanliness of the equipment and improving the user experience. The internal housing 18 not only provides a stable installation space for the first air pump 15 and the second air pump 16, but also isolates water, preventing water from damaging the air pumps and related circuits, ensuring the stable operation of the cold extraction cup.

[0047] A second sealing ring 19 is installed between the core housing 18 and the cold extraction chamber 11. The second sealing ring 19 can effectively prevent water in the cold extraction chamber 11 from entering the cup body 10 directly without going through the cold extraction process, and also prevent water in the cup body 10 from flowing directly into the cold extraction chamber 11.

[0048] The housing 18 is fitted with a main pipe 20 that connects to the cold extraction chamber 11. The first air pump 15 has a first branch pipe 21 and a second branch pipe 22 installed at both ends. The other end of the first branch pipe 21 connects to the main pipe 20, and the first branch pipe 21 and the main pipe 20 are integrally formed. The other end of the second branch pipe 22 connects to the outside. One end of the second air pump 16 connects to the second branch pipe 22, and the other end connects to the main pipe 20. The first air pump 15 and the second air pump 16 share the main pipe 20 and the second branch pipe 22, reducing the number of parts, lowering production costs, and simplifying the air circuit structure, making daily maintenance and troubleshooting more convenient. In terms of performance synergy, the two air pumps sharing these components enable more efficient gas exchange and pressure regulation. When the first air pump 15 draws gas from the cold brew chamber 11, the gas is discharged through the second branch pipe 22, maintaining the normal operation of the air pump. When the second air pump 16 is working, it can precisely inject gas into the cold brew chamber 11 through the shared main pipe 20, enhancing the consistency and accuracy of gas pressure control and further improving cold brew efficiency. Moreover, this shared design makes the gas path layout more compact and reasonable, and the entire cold brew cup structure is therefore more compact and lightweight, making it not only easy to carry but also allowing you to enjoy cold brew coffee anytime, anywhere. Operation is also simpler, making it easy for users to get started and greatly improving the user experience. In terms of cold brew effect, the closely connected gas path components allow the first air pump 15 and the second air pump 16 to precisely regulate the gas pressure inside the cold brew chamber 11.

[0049] A first water level sensor 23, extending into the cold extraction chamber 11, is installed on the core housing 18. This sensor monitors the water level in the cold extraction chamber 11 in real time, providing accurate water level data for the entire cold extraction process and enabling more intelligent automated control of the equipment. When the water level reaches the set upper or lower limit, the sensor promptly sends a signal, automatically controlling the start and stop of the first air pump 15 and the second air pump 16 to prevent cold extraction failure or equipment damage due to abnormal water levels.

[0050] A third sealing ring 25 is installed between the upper end of the mechanism housing 18 and the port of the cup body 10. A cup lid 26 is fixed to the top of the mechanism housing 18, and the cup lid 26 covers the cup body 10. The third sealing ring 25, together with the cup lid 26 fixed to the top, greatly enhances the sealing performance of the cup. The cup lid 26, when closed on the cup body 10, effectively prevents liquid from overflowing, avoiding spillage of coffee or water due to shaking during carrying. This ensures both ease of use and prevents liquid leakage from damaging the equipment. The third sealing ring 25 further strengthens the sealing effect, preventing outside air and dust from entering the cup body, ensuring that the coffee is not disturbed by external factors during the cold brewing process, and maintaining the freshness and purity of the coffee. At the same time, the good sealing performance also makes the cold brew cup safer and more reliable to carry. Whether placed in a backpack or held in hand, there is no need to worry about liquid leakage, allowing users to enjoy cold brew coffee anytime, anywhere with greater peace of mind.

[0051] Example 2

[0052] Example 2 is essentially the same as Example 1, except that a second water level sensor 24 is installed on the mechanism housing 18, extending into the cup body 10. The second water level sensor 24 can monitor the water level in the cup body 10 in real time. On one hand, this provides users with accurate water volume information, allowing them to adjust the ratio of coffee powder to water according to their actual needs, thus customizing a cold brew coffee that better suits their personal taste. On the other hand, during the cold brew process, the working state of the air pump can be adjusted promptly according to changes in the water level in the cup, ensuring the stability and smoothness of the cold brew process.

[0053] Example 3

[0054] Example 3 is basically the same as Example 2, except that the mechanism housing 18 is provided with a vent 181, which is located above the second water level sensor 24. The second water level sensor 24 can monitor the water level in the cup body 10 in real time. On the one hand, it provides users with accurate water volume information, making it convenient for users to adjust the ratio of coffee powder to water according to actual needs, thereby customizing cold brew coffee that better suits their personal taste.
