The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the first feature has a lower horizontal height than the second feature.

[0046] Such as Figures 1 to 8As shown in the figure, an automatically sliding coffee grinder and brewer includes a coffee grinding assembly 1 and a brewing assembly 2. The coffee grinding assembly 1 is used for grinding coffee beans. The brewing assembly 2 is equipped with a pressing seat body 207 for compacting coffee powder and completing brewing. A powder box moving assembly 3 is provided below both of them. The powder box moving assembly 3 includes a driving motor 303 and a coffee powder box 306. The driving motor 303 drives the coffee powder box 306 to perform a fully enclosed lateral transfer below both the coffee grinding assembly 1 and the brewing assembly 2. The driving motor 303 moves the coffee powder box 306 directly below the coffee grinding assembly 1 to receive the ground coffee powder. After the coffee powder box 306 is filled with coffee powder, it laterally moves below the brewing assembly 2. First, the pressing seat body 207 compacts the coffee powder, and then the brewing assembly 2 drains and brews the coffee powder. The powder box moving assembly 3 includes a moving lead screw 301 and a moving slide rail 302. The driving motor 303 is connected to the moving lead screw 301. The moving lead screw 301 is threadedly connected to a moving seat 305. The moving seat 305 is slidably connected to the moving slide rail 302. Micro switches 304 are provided at both ends of the moving slide rail 302. When the moving seat 305 moves to both ends, the micro switches 304 at both ends will be triggered respectively. At this time, the system can determine the position of the coffee powder box 306, and thus can determine whether the coffee machine needs to grind coffee or brew coffee.

[0047] The moving seat 305 is detachably connected to the coffee powder box 306, and a powder box handle 307 is provided on one side of the coffee powder box 306. In traditional coffee machines, after grinding coffee, it is necessary to manually take out the coffee powder box and then place it at the brewing assembly. This design is likely to cause coffee powder to spill during operation, which not only causes waste of coffee powder, but also the spilled coffee powder will pollute the operation tabletop, resulting in subsequent cleaning needs. Therefore, it will bring inconvenience to the operator. By driving the coffee powder box 306 to move between the coffee grinding assembly 1 and the brewing assembly 2 by the driving motor 303, the above problems can be avoided. Moreover, since the coffee powder remains inside the device from grinding to brewing, it can also prevent the coffee powder from being contaminated by the outside world, thereby further ensuring the flavor of the coffee.

[0048] A powder separation hopper 3061 and a foamer 308 are provided inside the coffee powder box 306. The powder separation hopper 3061 is provided with many micropores. The micropores can only pass coffee liquid but not coffee powder. A limiting convex particle 3062 is provided at the lower end outlet of the coffee powder box 306. A limiting groove 3083 is provided on the outer side of the lower end of the foamer 308. When the foamer 308 is installed inside the coffee powder box 306, the limiting convex particle 3062 is engaged with the limiting groove 3083. This not only enables the foamer 308 and the coffee powder box 306 to be quickly disassembled and assembled, but also makes their positions stable when they are installed together, so that the foamer 308 will not easily displace during the coffee brewing process.

[0049] Inside the frother 308, there is a coffee liquid guide groove 3081 arranged around the coffee liquid outlet 3082. The coffee liquid passes through the coffee liquid guide groove 3081 to extend the liquid path and the contact area with air, realizing the microbubble fusion of the coffee liquid, and finally enhancing the smooth taste of the coffee.

[0050] The brewing assembly 2 includes a water filling seat 204. The water filling seat 204 is slidably inserted into the stamping body 202. The lower end opening of the water filling seat 204 is blocked by a one-way valve 205. A one-way valve spring 206 is arranged on the side of the one-way valve 205 away from the water filling seat 204. When the water pump 8 starts pumping water, the water body enters the water filling seat 204. At this time, since the lower end of the water filling seat 204 is blocked by the one-way valve 205, the water cannot be discharged. The water pressure generated at this time causes the stamping body 202 to press downwards to compact the coffee powder. At this time, the stamping body 202 converts the water pressure energy into mechanical energy to realize the pre-compaction and densification of the coffee powder layer. When the water pressure continues to increase, finally the one-way valve 205 is flushed open, and the water is discharged from the lower end opening of the water filling seat 204 to brew the coffee powder.

[0051] A return spring 203 is arranged between the water filling seat 204 and the stamping body 202. After the coffee brewing stops, the brewing assembly 2 relieves pressure through the solenoid valve. At this time, the return spring 203 provides the reset power, enabling the coffee system to return to its original position, thus completing a cycle of coffee brewing.

[0052] A sealing ring 2041 is also arranged between the water filling seat 204 and the stamping body 202; the lower end of the stamping body 202 is connected to a lower pressing seat body 207, and the one-way valve spring 206 is arranged between the lower pressing seat body 207 and the one-way valve 205; the water filling seat 204 is arranged in the stamping housing 201, and the stamping housing 201 is connected to the coffee machine housing. The sealing ring 2041 forms a pressure cavity between the water filling seat 204 and the stamping body 202, thereby maintaining the pressure of the lower pressing seat body 207.

[0053] When the water pump 8 starts pumping water, the water pressure rises to 3 - 8 kg, and the stamping body 202 slides downward to tightly compress the coffee powder; the force for pressing the coffee powder is 9 - 12 kg. When the water pressure exceeds 9 - 12 kg, the one-way valve 205 is flushed open, and the brewing assembly 2 realizes the full-automatic coffee brewing process through an integrated fluid control structure. Its core working principle is that when the water pump 8 is started, the pressurized water flows through the water filling seat 204 to form a closed pressure cavity, forcing the stamping body 202 to press down on the coffee powder layer. When the pressure breaks through the set threshold of the one-way valve spring 206, the one-way valve 205 opens to achieve precise water injection. The brewing assembly 2 includes a double-seal guarantee, including the seal of the one-way valve 205 at the bottom of the water filling seat 204 and the sliding seal between the stamping body 202 and the water filling seat 204, ensuring the pressure stability under various working conditions.

[0054] This mechanism achieves automated control of the coffee brewing process through the coupling design of fluid dynamics and mechanical transmission. Its innovation lies in transforming the traditional manual compaction process into a pressure adaptive process. At the same time, it improves the operating reliability of the equipment through a multiple sealing guarantee system, providing a scalable technical solution for the design of professional-grade coffee machines.

[0055] The bean grinding assembly 1 includes an upper grinder 106 and a lower grinder 105, and the heights of the upper grinder 106 and the lower grinder 105 in the vertical direction are adjustable; the lower grinder 105 is connected to the lower grinder seat body 103, and the lower grinder seat body 103 is provided with a lifting thread ring 1031 on the outside; the lower grinder seat body 103 is connected to the lifting adjustment seat 102, and the lifting adjustment seat 102 is provided with an internal thread ring 1022 inside, and the lifting adjustment seat 102 is also provided with an external gear ring 1021 on the outside; the upper grinder 106 and the lower grinder 105 are precisely linked The adjustment structure realizes stepless adjustment of the vertical spacing between the upper and lower grinders through a composite mechanism of external gear drive and thread transmission. Its core working principle is: the external gear meshes with the external gear ring 1021 to drive the lifting thread ring 1031 to rotate and lift along the internal thread ring 1022 of the lifting adjustment seat 102, thereby adjusting the relative distance between the lower grinder seat body 103 and the upper grinder 106. This design converts rotational motion into linear displacement through the precise transmission characteristics of the thread pair, ultimately achieving continuous adjustable control of the fineness of coffee bean grinding.

[0056] The upper grinding knife 106 is coaxially connected to the first gear 107, and the first gear 107 is meshed with the second gear 1083; the second gear 1083 is coaxially connected to the worm wheel 1082, and the worm wheel 1082 is meshed with the worm 1081, and the worm 1081 is driven by the bean grinding drive motor 108. The lifting adjustment seat 102 is arranged in the powder outlet base 101, and the powder outlet base 101 is connected to the bean grinding base 104. Through the transmission of the worm gear and worm, the bean grinding drive motor 108 is used to finally drive the upper grinding knife 106 to rotate. Compared with the traditional method of using a motor to directly drive the grinding knife to rotate, this transmission method makes the motor less stressed and can effectively prevent the motor from being damaged due to excessive torque.

[0057] A coffee bean guide cover 109 is provided above the bean grinding base 104, and the coffee bean guide cover 109 is connected to the coffee bean box 6, so the operator only needs to put the coffee beans in the coffee bean box 6, and the coffee beans enter the bean grinding base 104 along the coffee bean guide cover 109, and the coffee beans can be ground as needed.

[0058] The brewing component 2 is connected to the pump body 8 through the switching valve 4. The pump body 8 is connected to the pot body 7, and the pot body 7 is connected to the water tank 5. The water in the water tank 5 is heated through the pot body 7, and then is pressurized and transported to the brewing component 2 through the pump body 8. The switching valve 4 can switch the circuit to select whether the input to the brewing component 2 is water or steam generated by the pot body 7. The steam generated by the pot body 7 can be used to foam the milk and then perform latte art on the coffee.

[0059] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
