[0037] In order to further understand the content, characteristics and effects of the present application, the following examples are given, and are described in detail as follows with reference to the accompanying drawings:
[0038] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the present application provides a full-automatic coffee machine, which comprises a grinding device 1 and a brewing device 2. The grinding device 1 has a powder outlet channel 11, and a flexible pipe 12 is arranged at the outlet of the powder outlet channel 11. The brewing device 2 comprises a mounting bracket 21, an extraction cup 22, a driving member, a moving member 23, a rotating member 24 and a powder receiving pipe 25. The mounting bracket 21 is arranged on one side of the grinding device 1. The extraction cup 22 is detachably arranged on the mounting bracket 21. The driving member, the moving member 23 and the rotating member 24 are all arranged on the mounting bracket 21, and the moving member 23 and the rotating member 24 are both connected with the driving member. The powder receiving pipe 25 is connected with the rotating member 24. The moving member 23 can move up and down under the driving of the driving member, and the rotating member 24 can drive the powder receiving pipe 25 to rotate under the driving of the driving member, so that the brewing device 2 can be switched among a first state, a second state and a third state. When the brewing device 2 is in the second state, one end of the flexible pipe 12 extends into the powder receiving pipe 25, and the powder outlet of the powder receiving pipe 25 faces the cup opening of the extraction cup 22.
[0039] In actual application, the full-automatic coffee machine further comprises a controller electrically connected with the powder grinding device 1 and the brewing device 2. When the full-automatic coffee machine is in standby state, the brewing device 2 is in the first state (i.e., one end of the flexible pipe 12 does not extend into the powder receiving pipe 25, and the powder outlet of the powder receiving pipe 25 is misaligned with the cup opening of the extraction cup 22). When the coffee is started to be made, first, the controller controls the driving member to drive the moving member 23 to move upward and drive the rotating member 24 to rotate toward the flexible pipe 12, so that the brewing device 2 is switched to the second state (i.e., one end of the flexible pipe 12 extends into the powder receiving pipe 25, and the powder outlet of the powder receiving pipe 25 faces the cup opening of the extraction cup 22). At this time, the coffee powder ground by the powder grinding device 1 can fall into the extraction cup 22 through the powder outlet channel 11, the flexible pipe 12 and the powder outlet pipe in turn. Second, the controller controls the driving member to drive the moving member 23 to move downward and drive the rotating member 24 to rotate away from the flexible pipe 12, so that the brewing device 2 is switched to the third state (i.e., one end of the flexible pipe 12 does not extend into the powder receiving pipe 25, and the powder outlet of the powder receiving pipe 25 is misaligned with the cup opening of the extraction cup 22, and the lower end of the moving member 23 extends into the extraction cup 22), so as to flatten the coffee powder in the extraction cup 22. Finally, the controller controls the driving member to drive the moving member 23 to move upward, so that the brewing device 2 is switched to the first state again, so as to extract coffee from the flattened coffee powder in the extraction cup 22.
[0040] Through the above technical solution, when the brewing device 2 is switched from the second state to the third state, the powder receiving pipe 25 can collide with the flexible pipe 12 to generate vibration, so that the coffee powder adhering to the inner wall of the powder outlet channel 11 falls into the extraction cup 22 under the action of vibration, ensuring that the amount of coffee powder falling into the extraction cup 22 is sufficient to ensure sufficient subsequent extraction, thereby ensuring the quality of the coffee made.
[0041] It can be understood that the number of driving members can be two. For the convenience of description, the two driving members are referred to as a first driving member and a second driving member. The first driving member is connected with the moving member 23 and is used to drive the moving member 23 to move up and down. The second driving member is connected with the rotating member 24 and is used to drive the rotating member 24 to rotate. Specifically, the first driving member can be a linear motion module, a screw pair transmission mechanism, a gear and rack transmission mechanism, a ball screw transmission mechanism or a servo motor transmission mechanism, etc. The second driving member can be a driving motor, a gear transmission mechanism or a worm and gear transmission mechanism, etc.

when the brewing device 2 is switched from the second state to the third state, the driving member drives the screw rod 213 to rotate in the opposite direction, the screw rod 213 rotates to drive the nut 215 to move downwards, thereby driving the moving member 23 to move downwards along the at least one guide rod 214, the screw rod 213 rotates to simultaneously drive the rotating block 242 to rotate in the opposite direction synchronously, the rotating block 242 rotates to drive the first rolling ball 245 and the elastic member 246 to rotate in the opposite direction synchronously, after the first rolling ball 245 rotates to correspond to the second through hole 2431, the elastic member 246 returns to the uncompressed state, the elastic force of the elastic member 246 makes one end of the first rolling ball 245 extend into the second through hole 2431, the first rolling ball 245 drives the rotating disc 243 to rotate in the opposite direction through the second through hole 2431, thereby driving the powder receiving tube 25 to rotate away from the flexible pipe 12, after the rotating disc 243 rotates to the other end of the arc-shaped limiting hole 2432 abutting against the screw 244, the rotating disc 243 no longer continues to rotate in the opposite direction, and the rotating block 242 continues to rotate with the screw rod 213 until the moving member 23 moves downwards to the position, the rotating block 242 continues to rotate, one end of the first rolling ball 245 is out of the second through hole 2431 and abuts against the bottom surface of the rotating disc 243, and the first rolling ball 245 continues to rotate with the rotating block 242, the moving member 23 moves downwards to drive the rotating member 24 and the powder receiving tube 25 to move downwards, at this time, the reset member 247 is compressed, after the moving member 23 moves downwards to the position, the moving member 23 and the connecting frame 241 together realize flattening of the coffee powder in the extraction cup 22.When the brewing device 2 is switched from the third state to the first state, the driving member drives the screw rod 213 to rotate, the screw rod 213 rotates to drive the nut 215 to move upwards, thereby driving the moving member 23 to move upwards along the at least one guide rod 214, when the moving member 23 moves upwards, the reset member 247 needs to restore the uncompressed state, the elastic force of the reset member 247 pushes the connecting frame 241 to move upwards synchronously with the moving member 23, after the moving member 23 moves to the position, the reset member 247 restores the uncompressed state, at this time, the moving member 23 still abuts against the connecting frame 241, the screw rod 213 rotates to drive the rotating block 242 to rotate synchronously, when the rotating block 242 rotates, the first rolling ball 245 and the elastic member 246 rotate synchronously, when the first rolling ball 245 rotates with the rotating block 242, the rotating disc 243 is driven to rotate through the second through hole 2431, but since the moving member 23 will block the powder pipe 25, therefore, the rotating disc 243 drives the powder pipe 25 to rotate at most to abut against the moving member 23, that is, the rotating disc 243 no longer rotates, and the rotating block 242 continues to rotate with the screw rod 213 until the moving member 23 moves to the position, when the rotating block 242 continues to rotate, one end of the first rolling ball 245 is out of the second through hole 2431 and abuts against the bottom surface of the rotating disc 243, and the first rolling ball 245 continues to rotate with the rotating block 242, at this time, the elastic member 246 is compressed, when the brewing device 2 is switched from the first state to the second state again, the first rolling ball 245 rotates to correspond to the second through hole 2431, and the elastic member 246 is reset, so that the first rolling ball 245 can drive the rotating disc 243 to rotate through the second through hole 2431.
[0044] Through the above technical scheme, one driving member can drive the moving member 23 to move and drive the rotating member 24 to rotate, compared with two driving members respectively driving the moving member and the rotating member 24, not only the production cost is greatly reduced, but also the structure of the full-automatic coffee machine is more compact, and the occupied space is smaller.
[0045] In order to ensure that the rotating disc 243 rotates uniformly, two first through holes 2421 are arranged on the rotating block 242, and the number of the first rolling ball 245, the elastic member 246 and the second through hole 2431 on the rotating disc 243 is two. Of course, the number of the first through hole 2421, the first rolling ball 245, the elastic member 246 and the second through hole 2431 can also be adaptively increased according to actual needs, and the above is only one embodiment of the present application, which should not be limited.
[0046] It should be noted that the complete thread section of the screw rod 213 refers to the thread of the side wall of the screw rod 213 being continuous, and the incomplete thread section of the screw rod 213 refers to the thread of the side wall of the screw rod 213 being discontinuous. Specifically, the incomplete thread section of the screw rod 213 can be to remove part of the thread of the side wall of the screw rod 213, so that the cross section of the incomplete thread section of the screw rod 213 is non-circular, so that the screw rod 213 can drive the rotating block 242 sleeved thereon to rotate synchronously when the screw rod 213 rotates, and the nut 215 can still move along the incomplete thread section of the screw rod 213 when the screw rod 213 rotates. In the embodiment, the screw rod 213 can drive the rotating block 242 sleeved thereon to rotate synchronously when the screw rod 213 rotates, and the nut 215 can still move along the incomplete thread section of the screw rod 213 when the screw rod 213 rotates by arranging two opposite planes on the incomplete thread section of the screw rod 213.
[0047] It can be understood that the connection of the driving motor and one end of the screw rod 213 can be that the output end of the driving motor and one end of the screw rod 213 are directly connected together through a shaft coupling, or indirectly connected together through a connecting mechanism, such as that one end of the screw rod 213 is connected with a worm gear, the output shaft of the driving motor is connected with a worm, and the worm and the worm gear are engaged. In this way, the driving motor drives the worm to rotate, the worm drives the worm gear to rotate, and the worm gear drives the screw rod 213 to rotate.
[0048] As shown in Figure 7 and Figure 8 In some preferred embodiments, the plurality of reset members 247 are sleeved on the incomplete thread section of the screw rod 213 and the at least one guide rod 214, respectively. Through this technical solution, the screw rod 213 and the guide rod 214 can guide and limit the reset member 247, so as to ensure that the connecting frame 241 can be accurately reset under the action of the reset member 247.
[0049] As shown in Figure 9 In some preferred embodiments, the rotating member 24 further comprises a second ball 248. The second ball 248 is located in the first through hole 2421 and abuts against the connecting frame 241. One end of the elastic member 246 abuts against the second ball 248. Through this technical solution, when the elastic member 246 rotates with the rotating block 242, the second ball 248 can reduce the friction between the elastic member 246 and the connecting frame 241, so as to reduce the wear of the elastic member 246 and the connecting frame 241, and also make the rotating block 242 rotate more smoothly.
[0050] As shown in Figure 1 and Figure 7As shown in the drawings, in some preferred embodiments, the lower mounting plate 212 is provided with a plurality of vertical plates 2122, each of which has an inwardly extending extension 2123 at an end away from the lower mounting plate 212, and the extension 2123 is in movable abutment with the connecting frame 241. Through this technical solution, the connecting frame 241 can be limited after being reset, so as to avoid the impact of the threads at the connecting position of the threaded complete section and the threaded incomplete section of the connecting frame 241.
[0051] Specifically, the number of vertical plates 2122 is three, and the three vertical plates 2122 are evenly arranged on the connecting frame 241. Of course, the number of vertical plates 2122 can also be adaptively increased or reduced according to actual needs, and the above is only one embodiment of the present application, which should not be limited.
[0052] As shown in the drawings, Figure 7 and Figure 8 in some preferred embodiments, the moving part 23 is provided with a first linear bearing 26, and the connecting frame 241 is provided with a second linear bearing 27, and the first linear bearing 26 and the second linear bearing 27 are sleeved on the guide rod 214. Through this technical solution, the friction between the moving part 23, the connecting frame 241 and the guide rod 214 can be reduced, so that the moving part 23 and the connecting frame 241 move more smoothly.
[0053] In order to avoid the displacement of the second linear bearing 27 in the axial direction relative to the connecting frame 241, Figure 7 and Figure 10 as shown in the drawings, in some preferred embodiments, the connecting frame 241 is provided with a stepped hole 2412, the second linear bearing 27 is located in the stepped hole 2412, and a limiting sleeve 28 is further arranged in the stepped hole 2412, the limiting sleeve 28 is in abutment with the second linear bearing 27, the side wall of the limiting sleeve 28 is provided with an elastic buckle 281, the side wall of the stepped hole 2412 is provided with a clamping hole 2413, and the elastic buckle 281 is located in the clamping hole 2413. Through the above technical solution, the second linear bearing 27 in the axial direction is effectively limited, so as to avoid the displacement of the second linear bearing 27 in the axial direction relative to the connecting frame 241.
[0054] In some preferred embodiments, the upper mounting plate 211 is provided with a first touch switch 29, and the lower mounting plate 212 is provided with a second touch switch 210. The touch button of the first touch switch 29 is in movable contact with the moving member 23, and the touch button of the second touch switch 210 is in movable contact with the connecting frame 241. In specific applications, the first touch switch 29 and the second touch switch 210 are both electrically connected to the controller of the fully automatic coffee machine. When the brewing device 2 is switched from the first state to the second state, the moving member 23 will touch the touch button of the first touch switch 29, and the first touch switch 29 will feed back a signal to the controller to ensure that the brewing device 2 has been switched from the first state to the second state. When the brewing device 2 is switched from the second state to the third state, the connecting frame 241 will touch the touch button of the second touch switch 210, and the second touch switch 210 will feed back a signal to the controller to ensure that the brewing device 2 has been switched from the second state to the third state. When the brewing device 2 is switched from the third state to the first state, the controller can determine whether the brewing device 2 has been switched to the first state according to the feedback of the current or the load condition of the driving motor. Of course, a third touch switch can also be provided to determine whether the brewing device 2 has been switched to the first state according to whether the moving member 23 or / and the connecting frame 241 touches the touch button of the third touch switch.
[0055] As shown in Figure 11 some preferred embodiments, the fully automatic coffee machine further comprises a water supply device, and the water outlet of the water supply device is in communication with the water channel 231 formed on the moving member 23. In specific applications, the water supply device is electrically connected to the controller of the fully automatic coffee machine. After the brewing device 2 is switched from the second state to the third state (i.e. after the coffee powder in the extraction cup 22 is flattened), the controller controls the water supply device to provide hot water to the brewing device 2, and the hot water flows into the extraction cup 22 through the water channel 231 to perform coffee extraction on the flattened coffee powder in the extraction cup 22. By providing the water channel 231 on the moving member 23, hot water can be injected into the extraction cup 22 through the water channel 231 after the brewing device 2 is switched to the third state, and it is not necessary to wait until the brewing device 2 is switched from the third state to the first state before injecting hot water into the extraction cup 22, which reduces the waiting time and improves the efficiency of making coffee.
[0056] As shown in Figure 12 and Figure 13As shown, in some preferred embodiments, the extraction cup 22 described above comprises a cup body 221, a movable cup 222, a bulging ring 223 and a valve. The cup body 221 is detachably arranged on the mounting bracket 21, and the bottom of the cup body 221 is provided with a first liquid outlet 2211. The movable cup 222 is detachably arranged in the cup body 221, and the bottom of the movable cup 222 is provided with a second liquid outlet 2221. When the movable cup 222 is arranged in the cup body 221, the second liquid outlet 2221 is communicated with the first liquid outlet 2211, the bulging ring 223 is located between the cup body 221 and the movable cup 222, and the cup body 221 and the movable cup 222 are in abutment with the bulging ring 223. The valve is arranged in the movable cup 222 and can close the second liquid outlet 2221. Through the above technical solution, the movable cup 222 can be detachably fixed in the cup body 221 under the elastic force of the bulging ring 223, so that after the coffee making is completed, the movable cup 222 can be detached from the cup body 221 for easy cleaning.
[0057] Specifically, the valve comprises a baffle 224, a buffer pad 225, a plug 226, a movable plug 227 and a return spring 228. The baffle 224 is arranged in the cup body 221, and the baffle 224 is provided with a liquid passage 2241. The buffer pad 225 is located between the baffle 224 and the bottom wall of the movable cup 222. The plug 226 is arranged at the outlet of the liquid passage 2241, and the plug 226 is provided with a liquid outlet hole 2261 communicated with the liquid passage 2241. The movable plug 227 is movably arranged in the liquid passage 2241 and movably abuts against the inlet of the liquid passage 2241. The return spring 228 is arranged in the liquid passage 2241, one end of the return spring 228 abuts against the plug 226, and the other end of the return spring 228 abuts against the movable plug 227. During the coffee extraction process, when the pressure in the movable cup 22 is greater than a predetermined pressure, the pressure pushes the movable plug 227 downward, forcing the return spring 228 to compress, so that the movable plug 42 no longer blocks the inlet of the liquid passage 2241, so that the extracted coffee liquid can flow out in sequence through the inlet of the liquid passage 2241, the liquid passage 2241, the liquid outlet hole 2261, the second liquid outlet 2221 and the first liquid outlet 2211. Through this technical solution, the coffee powder falling into the movable cup 22 through the powder outlet passage 11, the flexible pipe 12, the powder receiving pipe 25, the powder falling passage 2411 and the powder falling port 2121 can be fully extracted, further improving the extraction effect. In addition, when the moving part 23 presses the coffee on the baffle 224, the buffer pad 225 can increase the upward force on the baffle 224, so that the coffee powder is not pressed too tightly, so that good extraction effect can be achieved during subsequent coffee extraction. Specifically, the buffer pad 225 can be a silica gel pad.
[0058] To sum up, in one or more embodiments of the present application, the full-automatic coffee machine drives the rotating member to rotate the powder receiving tube by the driving member, so that the powder receiving tube collides with the flexible pipe to generate vibration, so that the coffee powder adhering to the inner wall of the powder outlet channel falls into the extraction cup under the action of vibration, ensuring that the amount of coffee powder falling into the extraction cup is sufficient to ensure sufficient subsequent extraction, thereby ensuring the quality of the coffee produced.
[0059] The above merely describes the embodiments of the present application and is not intended to limit the present application. The present application can be variously changed and modified by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of the claims of the present application.
