The grinding device 20 is connected to the bean box 102, and the bean box 102 stores coffee beans. The brewing device 50 includes a coffee basket body 502 and a coffee basket cover 501. The coffee basket cover 501 is provided with a water inlet channel 5011 and a powder inlet channel 5012. The coffee basket cover 501 is arranged on the coffee basket body 502. A filter is provided at the bottom of the coffee basket body 502.

[0042] The water supply device, the grinding device 20, the switch device 40, and the brewing device 50 are installed on the body 101, and the sealing plate 404 is movably connected to the body 101. The sealing plate 404 is provided with a water inlet hole 4041 and a powder inlet hole 4042, and the water inlet hole 4041 and the powder inlet hole 4042 are both connected to the coffee basket body 502; when the sealing plate 404 is in the first position, the water inlet hole 4041 is connected to the coffee basket body 502; when the sealing plate 404 is in the second position, the powder inlet hole 4042 is connected to the coffee basket body 502.

[0043] The sealing plate 404 is driven to the second position, the powder outlet channel 205 and the powder inlet hole 4042 are aligned with the powder inlet channel 5012, and the coffee powder enters the coffee basket body 502 through the powder inlet hole 4042. Then the motor 401 drives the sealing plate 404 to the first position, the powder inlet hole 4042 is misaligned with the powder inlet channel 5012, the sealing plate 404 blocks the powder inlet hole 4042, the water outlet channel 304 and the water inlet hole 4041 are aligned with the water inlet channel 5011, and hot water is put into the coffee basket body 502 through the water inlet hole 4041.

The coffee cup 104 is received; the coffee basket 502 is sealed, and pressurized hot water enters the coffee basket 502. The vaporization of hot water will also generate a certain air pressure. The pressure in the coffee basket 502 can promote the extraction of powder and water, and improve the taste of coffee; the coffee machine realizes the connection and sealing pressurization of the coffee basket 502 through the sliding of the sealing plate 404. It has a simple structure, light volume, and easy maintenance. The pressure generated in the sealed coffee basket 502 improves the coffee extraction, ensuring that the aroma of coffee beans can be extracted into the coffee at the first time. The coffee beans are stored in the bean box 102, and the unground coffee beans can retain the bean aroma for a long time without being affected by moisture.

[0044] The brewing device 50 also includes a first sealing ring 601, a second sealing ring 602, a third sealing ring 603, a shower head 504, and a coffee basket rack 503. The first sealing ring 601 is arranged at the connection between the machine body 101 and the sealing plate 404, the second sealing ring 602 is arranged at the connection between the coffee basket cover 501 and the sealing plate 404, the third sealing ring 603 and the shower head 504 are arranged between the coffee basket body 502 and the coffee basket cover 501, the first sealing ring 601 ensures the airtightness between the machine body 101 and the sealing plate 404, the second sealing ring 602 ensures the airtightness between the coffee basket cover 501 and the sealing plate 404, and the third sealing ring 603 ensures the airtightness between the coffee basket body 502 and the coffee basket cover 501. The first sealing ring 601, the second sealing ring 602, and the third sealing ring 603 are all used to ensure the sealing inside the coffee basket 502, so that the hot water can be fully vaporized and expanded inside the coffee basket 502 to squeeze the coffee.

[0045] The shower head 504 is fixed on the powder inlet channel 5012. The function of the shower head 504 is to make the coffee powder evenly spread when entering the coffee basket 502, and cover the filter at the bottom of the coffee basket 502, so as to ensure that the hot water forms a paste of coffee water after entering and covers the filter, so that the air tightness of the coffee basket 502 is maintained; the coffee basket rack 503 is arranged on the outside of the coffee basket 502 and the coffee basket 502 is fixed to the machine body 101 through the coffee basket rack 503.

[0046] like Figures 4 to 7As shown, the motor 401 is in driving connection with the transmission wheel 402, one side of the pin shaft 403 is fixed to the transmission wheel 402, and the other side is movably connected to the sealing plate 404, the sealing plate 404 is provided with the water inlet hole 4041 and the powder inlet hole 4042, and the sealing plate 404 is located between the machine body 101 and the brewing device 50.

[0047] The motor 401 drives the transmission wheel 402 to make a circular motion. The transmission wheel 402 is a cam. The circular motion of the transmission wheel 402 is converted into a linear motion of the sealing plate 404 through the pin shaft 403 and the through hole 4043, which is equivalent to a "cam-connecting rod" mechanism. During the rotation of the transmission wheel 402, the pin shaft 403 pulls the sealing plate 404 to make a linear motion. The position of the pin shaft 403 on the through hole 4043 changes continuously with the rotation angle of the transmission wheel 402, so that the sealing plate 404 is always in a straight line; the guide rail 5013 on the coffee basket cover 501 limits the two sides of the sealing plate 404, and the sealing plate 404 can only make a linear motion on the coffee basket cover 501.

The pressure water supply component 303 is connected to the water tank 301 , and the heating component 302 is arranged on the pressure water supply component 303 . The pressure water supply component 303 includes a pressure valve. After the water enters the coffee machine, it is heated to a certain temperature by the heating component 302 and then stored in the water tank 301. When the coffee machine needs hot water to brew coffee powder, the hot water is pressurized to a certain degree through the pressure valve and then sprayed out from the water outlet channel 304, and enters the coffee basket 502 through the water inlet hole 4041 and the water inlet channel 5011; the hot water enters the coffee basket 502 and mixes with the coffee powder to initially form a paste of coffee water, which blocks the filter at the bottom of the coffee basket 502, forming a sealed space in the coffee basket 502, and the pressurized hot water will vaporize and expand in the coffee basket 502, pressurizing the paste of coffee water, thereby improving the extraction effect of coffee powder and water, and the paste of coffee water flows out of the filter after being pressurized and is caught by the coffee cup 104 to obtain edible coffee.

[0049] The grinding device 20 includes a power mechanism 204 , a transmission mechanism 201 , an inner grinding wheel 202 , and an outer grinding wheel 203 . The power mechanism 204 is in transmission connection with the transmission mechanism 201 , the inner grinding wheel 202 is fixed to the transmission mechanism 201 , and the outer grinding wheel 203 is sleeved on the inner grinding wheel 202 .

[0050] The power mechanism 204 rotates to drive the transmission mechanism 201, and the transmission mechanism 201 transmits power to the inner grinding wheel 202. The transmission mechanism 201 is a torque transmission mechanism 201. The inner grinding wheel 202 has teeth on the outside, and the outer grinding wheel 203 has teeth on the inside. The outer grinding wheel 203 is fixed, and the inner grinding wheel 202 is driven to rotate. The outer grinding wheel 203 and the inner grinding wheel 202 rotate relative to each other.
