Description

Technical Field

[0001] This utility model belongs to the field of coffee equipment technology, specifically a simple, portable, and multifunctional coffee equipment. Background Technology

[0002] Coffee, as a globally popular beverage, has a wide variety of brewing equipment, ranging from traditional pour-over kettles and French presses to modern semi-automatic and fully automatic coffee machines. Each type of equipment has its unique working principle and application scenarios. However, existing coffee equipment still has certain limitations in terms of portability and versatility.

[0003] Traditional coffee makers include: pour-over kettles: While simple to use, pour-over requires more tools (such as filter paper and filter cups) and the process is time-consuming, making it unsuitable for fast-paced lifestyles. French presses: Although easy to use, French presses don't completely separate the coffee liquid from the grounds and cannot froth milk. Semi-automatic / fully automatic coffee machines: While powerful, these machines are bulky, inconvenient, and expensive, making them unsuitable for outdoor or travel use.

[0004] To address the aforementioned issues, a simple, portable, and multifunctional coffee maker is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the above problems by providing a simple, portable, and multifunctional coffee maker, comprising:

[0006] The water tank has a top cover and a powder tank at its upper and lower ends, respectively. A piston connecting rod is slidably connected to the middle of the powder tank. A handle is fixedly installed on the top of the piston connecting rod. A piston liner is threadedly connected to the bottom of the piston connecting rod. A piston seal is fixedly installed on the outer wall of the piston liner. The piston seal is slidably connected to the inside of the water tank.

[0007] With the above technical solution, when positive pressure extraction of coffee is required, first remove the coffee grounds from the bottom of the water tank, then place the filter paper on the upper surface of the coffee grounds and put in the ground coffee powder. Place the coffee grounds above the mouth of the water cup, then pour hot water into the coffee grounds. After waiting for a while, place the water tank on top of the coffee grounds and squeeze the handle downwards. The handle is forced to move the piston down inside the water tank, thereby performing positive pressure extraction of the coffee liquid. When reverse pressure is required, pour the coffee powder and water into the water tank. The water tank can serve as both a coffee container and a reverse pressure extraction device. When milk frothing and juice extraction are required, simply remove the piston liner at the end of the piston connecting rod and replace it with the corresponding operating parts to achieve the functions of milk frothing and juice extraction.

[0008] In a preferred embodiment, the water tank is provided with external threads at both the upper and lower ends, and the upper cover and the inner wall of the powder tank are provided with internal threads that are compatible with the external threads.

[0009] With the above technical solution, both the top cover and the powder hopper are connected by threads, which facilitates installation and disassembly.

[0010] In a preferred embodiment, the lower wall of the powder hopper is provided with a plurality of filtrate holes.

[0011] In a preferred embodiment, the upper surface of the cover has a connection hole at its center that is adapted to the piston connecting rod.

[0012] In a preferred embodiment, the upper surface of the cover has drinking spouts on both sides.

[0013] With the above technical solution, coffee can be drunk directly without opening the lid by setting a direct drinking spout.

[0014] In a preferred embodiment, a sealing ring is fixedly installed on the inner wall of the connection hole.

[0015] The above technical solution improves the sealing performance between the connecting hole and the piston connecting rod by setting a sealing ring.

[0016] In summary, due to the adoption of the above technical solutions, the beneficial effects of this utility model are: this utility model proposes a simple, portable, and multifunctional coffee maker.

[0017] Remove the coffee grounds container from the bottom of the water tank. Place the filter paper on the top surface of the coffee grounds container and add the ground coffee powder. Place the coffee grounds container above the mouth of the water cup, then pour hot water into the coffee grounds container. After waiting for a while, place the water tank on top of the coffee grounds container and press down on the handle. The handle will cause the piston to move down inside the water tank, thus performing positive pressure extraction of the coffee liquid. When reverse pressure is needed, pour coffee powder and water into the water tank. The water tank can serve as both a coffee container and a reverse pressure extraction device. When you need to froth milk or squeeze juice, simply remove the piston liner at the end of the piston connecting rod and replace it with the corresponding operating parts to achieve the functions of frothing milk and squeezing juice.
