Abstract
Description
Technical Field
[0001] This utility model relates to a portable cold brew coffee maker, belonging to the field of kitchenware. Background Technology
[0002] Cold brew coffee, as a new type of coffee brewing beverage, is gradually becoming popular in the market. It mainly involves steeping coffee powder in cold or ice water for a long time to extract the flavor substances of coffee, thus avoiding the bitterness caused by traditional hot water brewing. The container involved is a cold brew pot.
[0003] However, existing cold brew coffee makers, especially portable ones, have poor sealing performance. Many products lack an effective sealing design at the connection between the lid and the body, making them prone to leakage during transport. Furthermore, their filter structures are complex and difficult to clean, and the process of disassembling and assembling the filter is cumbersome. In addition, the capacity markings on existing cold brew coffee makers are not clear enough, making it difficult for users to accurately control the ratio of coffee powder to water during brewing.
[0004] These problems severely impact user experience and product market competitiveness. Therefore, developing a portable cold brew coffee maker that is well-sealed, easy to clean, and clearly labeled with its capacity is a pressing issue in this field. Summary of the Invention
[0005] In view of this, the present invention provides a portable cold brew coffee maker to solve the above-mentioned problems existing in the prior art.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0007] A portable cold brew coffee maker includes a bottle body, a cap that is fastened to the upper part of the bottle body, and a filter mechanism that is detachably connected to the cap body and extends into the inner cavity of the bottle body.
[0008] The cover has a drain hole and a mounting hole. The drain hole extends upward and is connected to a screw cap via a thread. A baffle is detachably connected to the upper edge of the mounting hole. The filter mechanism is detachably connected to the lower edge of the mounting hole.
[0009] Based on the above technical solution, the present invention can be further improved as follows.
[0010] Furthermore, the filtration mechanism includes a filter body with openings on both opposite end faces, and a filter top cover and a filter bottom cover that are detachably connected to the two openings respectively.
[0011] Furthermore, a fixing seat is threaded onto the mounting hole, and the baffle is detachably connected to the mounting hole via the fixing seat.
[0012] Furthermore, the outer diameter of the filter mechanism is smaller than the inner diameter of the mounting hole, and the upper end face of the filter top cover has a lifting plate.
[0013] Furthermore, a sealing ring is provided on the lower end face of the fixing base.
[0014] Furthermore, a sealing ring is provided on the lower end face of the screw cap.
[0015] Furthermore, the outer wall of the bottle has capacity markings.
[0016] The beneficial effects of this utility model are:
[0017] This portable cold brew coffee maker features excellent sealing, easy cleaning, high portability, and clear capacity markings. While maintaining a convenient carrying structure, it effectively prevents leakage through a sealing ring. The detachable filter greatly simplifies cleaning, reducing time and effort required. Its compact design significantly reduces the product's size, making it more suitable for outdoor activities and travel. Furthermore, the clear capacity markings provide users with precise measurement references, ensuring accurate control of the coffee powder-to-water ratio, thereby enhancing the coffee's flavor and improving the user experience. It possesses significant market application value. Attached Figure Description

[0019] Figure 2 This is an exploded view of the structure of this utility model;
[0020] Figure 3 This is a cross-sectional view of the structure of this utility model.
[0021] The attached diagram lists the components represented by each number as follows:
[0022] 1. Bottle body, 2. Cap body, 3. Pouring hole, 4. Mounting hole, 5. Screw cap, 6. Baffle, 7. Filter screen body, 8. Filter screen top cover, 9. Filter screen bottom cover, 10. Fixing base. Detailed Implementation
[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0024] like Figure 1-3 As shown, a portable cold brew coffee maker includes a bottle body 1, a cap 2 that is fastened to the upper end of the bottle body 1, and a filter mechanism that is detachably connected to the cap 2 and extends into the inner cavity of the bottle body 1.
[0025] The cover 2 has a drain hole 3 and a mounting hole 4. The drain hole 3 extends upward and is connected to a screw cap 5 by a thread. A baffle 6 is detachably connected to the upper edge of the mounting hole 4. The filter mechanism is detachably connected to the lower edge of the mounting hole 4.
[0026] In another embodiment of the present invention, the filter mechanism includes a filter body 7 with openings on both opposite end faces, and a filter top cover 8 and a filter bottom cover 9 detachably connected to the two openings respectively. The filter mechanism can be disassembled for easy cleaning.
[0027] In another embodiment of this utility model, a fixing seat 10 is threadedly connected to the mounting hole 4, and the baffle 6 is detachably connected to the mounting hole 4 through the fixing seat 10. Under the premise of installing the baffle 6, the installation of the fixing seat 10 can form an abutment against the filter mechanism, thereby increasing its installation stability.
[0028] In another embodiment of this utility model, the outer diameter of the filter mechanism is smaller than the inner diameter of the mounting hole 4, and the upper end face of the filter top cover has a lifting piece.
[0029] In another embodiment of this utility model, a sealing ring is provided on the lower end face of the fixing base 10 to prevent water leakage.
[0030] In another embodiment of this utility model, a sealing ring is provided on the lower end face of the screw cap 5 to prevent water leakage.
[0031] In another embodiment of this utility model, the outer wall of the bottle body 1 has a capacity scale, which can be optionally set to 200ml, 400ml, 600ml, 800ml and / or 1000ml for accurate measurement of liquid volume.
[0032] Before cold brewing, there is no need to remove the cap 2 from the bottle 1. Simply unscrew the baffle 6 and remove the fixing seat 10, take out the filter mechanism through the lifting tab, open the filter top cover 8, add coffee powder, and pour water into the bottle 1. Then, put the filter mechanism, fixing seat 10 and baffle 6 back in sequence to perform cold brewing. After cold brewing, open the cap 5 to pour out the coffee liquid. After use, the parts can be disassembled one by one for thorough cleaning to ensure the effect of the next use.
[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
