Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, and more specifically, to a coffee machine brewing head with pressure balancing function. Background Technology

[0002] There are many types of coffee machines available now, with drip coffee machines being the most popular. The brewing head of a drip coffee machine consists of a fixed part and a lid that can be opened and closed relative to the fixed part. When the lid and fixed part are closed, they form a sealed cavity. During brewing, a coffee bag containing coffee powder is placed inside this sealed cavity. Hot water, boiled by the coffee machine, is pumped into the cavity containing the coffee bag, allowing the coffee powder to drip through. During drip brewing, it is crucial to ensure that the sealed cavity formed by the lid and fixed part does not leak. Therefore, the lid and fixed part must be locked together. After brewing, the lid is opened relative to the fixed part, and the brewed coffee bag is removed.

[0003] Current coffee machine brewing heads suffer from pressure imbalance during use, which can lead to uneven extraction, leakage, or failure to dispense liquid properly. A coffee machine brewing head with pressure balancing function is needed to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a coffee machine brewing head with pressure balancing function to solve the problems mentioned in the background art.

Detailed Implementation

[0021] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0022] Example 1

[0023] refer to Figures 1 to 2 Example 1 describes a main body 1 with a placement groove 2 and a drip tray 3 for placing coffee cups. A filter 7 is installed on the drip tray 3 and screwed onto the main body 1. The filter 7 consists of a brewing mesh head 16, a diaphragm assembly 17, and a secondary water distribution mesh 18. A brewer 6 is installed on the side of the main body 1, and a movable top cover 10 for protecting the water tank is installed on the top of the main body 1. The movable top cover 10 is rotatably connected to the main body 1 via a movable shaft 11, and a handle 12 is fixedly installed on the movable top cover 10. The drip tray 3 has multiple slots 4 that communicate with the drip tray 3. A control switch 5 is installed on the side of the main body 1 to control the operation of the main body 1.

[0024] In this embodiment, the drip tray 3 is provided with multiple slots 4, and the slots 4 are connected to the drip tray 3, which helps to drain excess water and keep the coffee machine clean.

[0025] Example 2

[0026] refer to Figures 2 to 3 Example 2 is a further description of Example 1. It includes a diaphragm assembly 17, which is provided with a diaphragm block 19. The diaphragm assembly 17 is divided into a first chamber 21 and a second chamber 22 by the diaphragm block 19. The diaphragm block 19 is provided with a plurality of small holes 20, which allow the first chamber 21 and the second chamber 22 to communicate.

[0027] In this embodiment, the diaphragm block 19 in the diaphragm assembly 17 divides it into a first chamber 21 and a second chamber 22. Hot water flows between the two chambers through small holes 20 on the diaphragm block 19. The small holes 20 on the diaphragm block 19 further optimize the water flow regulation effect. This structure enables the hot water to achieve pressure balance during the flow process.

[0028] In practical application, firstly, install the drip tray 3 on the placement slot 2 of the main body 1, ensuring a stable installation. Then, screw the filter 7 onto the main body 1 via the handle 13, ensuring that the arc-shaped groove 14 of the filter 7 accurately matches the diaphragm assembly 17. Next, connect the movable top cover 10 to the main body 1 via the movable shaft 11, ensuring that the movable top cover 10 can rotate freely. Place the coffee cup on the drip tray 3, ready to brew coffee. During the brewing process, press the control switch 5 on the side of the main body 1 to start the coffee machine main body 1. At this time, the brewer 6 starts working, delivering hot water to the filter 7. After entering the filter 7, the hot water undergoes preliminary filtration through the brewing mesh head 16, and then reaches the diaphragm assembly 17. The diaphragm baffle 19 in the diaphragm assembly 17 divides the space into a first chamber 21 and a second chamber 22. Hot water flows between the two chambers through small holes 20 on the diaphragm baffle 19. These small holes further optimize the water flow regulation, allowing the hot water to achieve pressure balance during flow and preventing excessive or insufficient local pressure, thus ensuring uniform extraction of the coffee grounds. After pressure balancing, the hot water continues to be further dispersed through a secondary water separator 18, then fully contacts the coffee grounds to extract the coffee liquid. The coffee liquid flows out through the outlet channel 15 at the bottom of the filter 7 and drips into the coffee cup below.
