They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "left," "right," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0051] The brewer provided in this embodiment can be used to brew coffee, such as... Figure 2-4 It includes the processes of receiving materials, pressing powder, brewing, and slag removal.

[0052] The above-mentioned brewing device, such as Figure 1 , Figure 2 It mainly includes components such as motor 1, camshaft 2, support rod 31, cylindrical left powder tank 5, left top seat assembly 6, cylindrical right powder tank 8, and right top seat assembly 9.

[0053] like Figure 2The brewer has a fixed plate 3 on each side. The camshaft 2 is rotatably mounted between the two fixed plates 3 via bearings. The output end of the motor 1 is connected to the camshaft 2 and drives the camshaft 2 to rotate. The rotation of the camshaft 2 then drives the left powder container 5 and the right top seat assembly 9 to move linearly.

[0054] like Figure 1 Four cylindrical support rods 31 are installed between the two fixed plates 3. The left powder bucket 5 and the right top seat assembly 9 are connected to the support rods 31 through the left connecting frame 4 and the right connecting frame 7, respectively. The left connecting frame 4 and the right connecting frame 7 are respectively equipped with cylindrical sleeves that can be fitted onto the outside of the support rods 31, so that the left connecting frame 4 and the right connecting frame 7 can slide linearly along the support rods 31. The support rods 31 provide support and guidance for the linear movement of the left connecting frame 4 and the right connecting frame 7.

[0055] like Figure 1 , Figure 2 , Figure 8 The left powder bucket 5 and the right top seat assembly 9 are respectively placed on both sides along the axial direction of the camshaft 2. A left motion groove 21 is formed on the side wall of the camshaft 2 corresponding to the left powder bucket 5, which is around the camshaft 2. Figures 10 to 13 On the other side wall of the right top seat assembly 9, corresponding to the camshaft 2, a right motion groove 22 is formed around the camshaft 2; the left connecting bracket 4 has a left guide rod 41 placed in the left motion groove 21, such as Figure 6 , Figure 14 This allows the left connecting frame 4 to move along the support rod 31 by cooperating with the left motion groove 21 and the left guide rod 41 when the camshaft 2 rotates, thus causing the left powder bucket 5 to move linearly; the right connecting frame 7 has a right guide rod 71 placed in the right motion groove 22, such as Figure 15 This allows the right motion groove 22 to drive the right connecting bracket 7 to move the right top seat assembly 9 in a straight line when the camshaft 2 rotates.

[0056] It should be noted that the specific distribution of the aforementioned left and right motion slots around the camshaft is as follows: Figures 10 to 13 As shown, this is only one embodiment. Other distribution configurations that can satisfy the driving functions of the left and right motion slots of this application by opening two motion slots on the same camshaft are also within the protection scope of this application.

[0057] Thus, a drive source consisting of a motor 1 and a camshaft 2 can be used to drive the linear movement of the left powder tank 5 and the right top seat assembly 9, thereby enabling the left powder tank 5 and the right top seat assembly 9 to be configured with different mating positions for different work processes.

[0058] The aforementioned brewing device uses a single motor 1 as its driving source, which changes the cumbersome structure of traditional dual-motor systems and improves energy efficiency and convenience. Furthermore, the camshaft 2 is horizontally distributed, and the left powder container 5 and right top assembly 9 are designed to be distributed along the axial direction of the camshaft 2. The left powder container 5 and right powder container 8 are coaxially and horizontally distributed, making the brewing device horizontal overall, which changes the traditional vertical structure of brewing devices and saves vertical space.

[0059] The aforementioned left top seat assembly 6, such as Figure 6 , Figure 7 It includes a left top bracket 61, two connecting water nozzles, a left top bracket 64, a left sealing ring 65, and a left filter screen 66. The left top bracket 61 is installed on the left fixing plate 3 to fix the position of the left top bracket assembly 6 as a whole. Two connecting water nozzles are installed inside the left side of the left top bracket 61, and the left top bracket 64 is installed on the right side of the left top bracket 61.

[0060] The left top seat 64 is cylindrical. A left sealing groove 641 is formed on the outer circumferential side wall of the left top seat 64. A left sealing ring 65 is installed inside the left sealing groove 641. An inner groove is formed on the inner side of the left sealing ring. A first through hole 642 is formed on the left end face of the left top seat 64, which communicates with the left sealing groove 641 and the inner groove. A connecting water nozzle is connected to the first through hole 642 through a water pipe 67. Water is supplied to the connecting water nozzle (this connecting water nozzle is called the left sealing water nozzle 62). Water is injected into the left sealing groove 641 through the water pipe 67 and the first through hole 642, thereby squeezing the left sealing ring 65 to expand outward. The left powder tank 5 is fitted onto the outside of the left top seat 64. The expansion of the left sealing ring 65 makes the left sealing ring 65 fit and seal against the inner wall of the left powder tank 5. This achieves the sealing of the left top seat 64 and the left powder tank 5 by continuously injecting water. With the continuous expansion effect of the left sealing ring 65, the left top seat 64 and the left powder tank 5 can also maintain a sealing effect when the left powder tank 5 moves in a straight line.

[0061] A left filter screen 66 is installed on the right end face of the left top seat 64. A second through hole 643 is opened in the left end face of the left top seat 64, penetrating the right end face of the left top seat. Another connecting water nozzle (this other connecting water nozzle is called the left rinsing water nozzle 63) is connected to the second through hole 643 through a water pipe 67. When water is injected into the left rinsing water nozzle 63, the water flows out after passing through the second through hole 643 and the left filter screen 66.

[0062] The right powder hopper 8 is mounted on the right side of the right fixed plate 3, and the right top mount assembly 9 is linearly movable and mounted on the right powder hopper 8. This right top mount assembly 9, as... Figure 8 , Figure 9 It includes components such as the right top seat 91, two connecting water nozzles, right sealing ring 94, right filter screen 95, cap 96, control valve 97, top cover 975, plug 976, and spring 977.

[0063] The right top seat 91 is cylindrical and can be linearly moved and installed inside the right powder hopper 8; for example... Figure 5 A cylindrical guide barrel 98 is installed on the right end face of the right top seat 91. A connecting rod 72 is installed between the guide barrel 98 and the right connecting frame 7. Figure 8 , Figure 16 A travel groove 81 is provided on the side wall of the right powder hopper 8. When the right connecting frame 7 pushes the right top seat assembly 9 to move linearly, the connecting rod 72 moves within the travel groove 81. A cover plate 73 is also installed on the connecting rod 72 to cover the travel groove. The cover plate 73 is located outside the travel groove and has a discharge port 731 with its opening facing upwards. The cover plate 73 and the right top seat 91 move linearly synchronously on the inside and outside of the right powder hopper 8, respectively, driven by the right connecting frame 7. The travel groove serves to allow the connecting rod 72 to move without obstruction and also connects the discharge port 731 to the inner cavity of the right powder hopper 8 during the material receiving process. The cover plate 73 not only serves as a carrier for the discharge port 731, but other parts of the cover plate 73 also cover the travel groove 81.

[0064] like Figure 9 A right sealing groove 912 is formed on the outer circumferential side wall of the right top seat 91. A right sealing ring 94 is installed inside the right sealing groove 912. A third through hole 911 connected to the right sealing groove 912 is formed on the right end face of the right top seat 91. A connecting water nozzle of the right top seat assembly 9 is connected to the third through hole 911. Water is injected into the right sealing groove 912 by the connecting water nozzle (the connecting water nozzle is called the right sealing water nozzle 92), which in turn squeezes the outer side of the right sealing ring 94 to expand, so that the right sealing ring 94 fits and seals against the inner side wall of the right powder tank 8. The right top seat 91 and the right powder tank 8 are assembled and sealed by continuous water injection. With the continuous expansion effect of the right sealing ring 94, the right top seat 91 and the right powder tank 8 can also maintain a sealing effect when the right top seat 91 moves linearly inside the right powder tank 8.

[0065] The aforementioned control valve 97 includes a cylindrical valve body 971 and a disc-shaped seat 972. An outlet channel is formed in the center of the seat 972. The valve body 971 has a mounting hole 973 on its left side and a fourth through hole 974 communicating with the mounting hole 973 on its right side. A spring 977, a plug 976, and an annular top cover 975 are sequentially installed in the mounting hole 973 from right to left. One end of the plug 976 abuts against the center hole of the top cover 975, and the other end is connected to the spring. 977, the seat 972 is installed on the left end face of the right top seat 91, with the middle of the seat 972 pressing against the top cover 975. The seat installation design facilitates the removal of the control valve from the right top seat for cleaning or replacement. The outlet channel of the seat 972 communicates with the center hole of the top cover 975. When the water pressure from the left side drives the plug 976 to move to the right to release the blockage on the top cover 975, the outlet channel of the seat 972 communicates with the fourth through hole 974 to supply water. The valve body 971, seat 972, and the internal top cover 975, plug 976, and spring 977 together constitute a control valve 97 that is normally closed but can be opened under liquid pressure. The control valve 97 is normally closed, and liquid cannot flow. During the brewing process, the control valve 97 opens under liquid pressure to allow coffee liquid to flow out, thus controlling the opening and closing of the coffee liquid flow channel. Of course, in other embodiments, an electrically controlled control valve can also be used, which opens and closes at set times according to the brewing time. Such electrically controlled control valves are existing technology, and the principle and structure of opening and closing the electrically controlled valve will not be described in detail here.

[0066] The right filter screen 95 is installed inside the cap 96, which is installed on the left end of the right top seat 91, such that the seat 972 of the control valve 97 is placed inside the cap 96. An installation cavity 913 is provided on the left end face of the right top seat 91, and the valve body 971 of the control valve 97 is sealed and installed in the installation cavity 913. Another connecting water nozzle (called the right brewing water nozzle 93) is installed on the right end face of the right top seat 91, which connects to the fourth through hole 974. The coffee liquid flows out after passing through the left filter screen 95, the open control valve 97, the fourth through hole 974, and the right brewing water nozzle 93.

[0067] The process of receiving materials, pressing powder, brewing, and discharging slag using the above-mentioned brewing device is as follows:

[0068] Material receiving process: such as Figure 1 Before operation, the left powder bucket 5 and the right top seat assembly 9 are in their initial positions as the left top seat assembly 6 and the right powder bucket 8, respectively. The starter motor 1 drives the camshaft 2 to rotate clockwise. The camshaft 2 drives the left connecting bracket 4 to move the left powder bucket 5 to the right, i.e., towards the side where the right powder bucket 8 is located, until the left powder bucket 5 and the right powder bucket 8 come into contact. Figure 2 , Figure 3At this time, the left top seat 64 is still inside the left powder container 5, which causes the left powder container 5, the right powder container 8, the left top seat assembly 6, and the right top seat assembly 9 to enclose a receiving space 10 for receiving coffee powder (a material to be brewed; this embodiment uses brewed coffee powder as an example). The discharge port 731 is located above the receiving space 10, and the coffee powder falls into the receiving space 10 from the discharge port 731.

[0069] The tamping process: Motor 1 drives camshaft 2 to continue rotating clockwise, causing the right top seat assembly 9 to move to the left, i.e., toward the side where the left powder container 5 is located, thus pushing the coffee powder. A brewing space 11 is formed between the left filter 66 and the right filter 95, and the coffee powder is pushed and compressed within the brewing space 11. Figure 3 In this embodiment, the brewing space 11 is located inside the left powder container 5, meaning the coffee powder is pushed into the left powder container. At this time, the brewing space is formed by the left powder container 5, the left filter 66, and the right filter 95. Of course, in other embodiments, the coffee powder may not be entirely pushed into the left powder container, but may remain in the right powder container. In this case, the brewing space is formed by the left and right powder containers together, along with the left and right filters. During this tamping process, the left powder container 5 remains stationary; tamping is achieved by the movement of the right top assembly.

[0070] Brewing process: as follows Figure 1 , Figure 3 First, water is injected using the left sealing nozzle 62 and the right sealing nozzle 92 so that the left sealing ring 65 adheres to the inner wall of the left powder tank 5 and the right sealing ring 94 also adheres to the inner wall of the left powder tank 5 (in this embodiment, the right sealing ring 94 of the right top seat assembly 9 has been pushed into the left powder tank 5, such as...). Figure 3 This seals the left top seat 64 and right top seat 91 with the inner wall of the left powder container 5, ensuring that the brewing liquid (in this embodiment, water is used as an example) will not leak from the gap between the left top seat 64, right top seat 91 and the brewing space 11 during brewing; then, hot water is injected into the left brewing spout 63, such as... Figure 1 The flow path indicated by the middle arrow is as follows: after flowing out from the second through hole 643 of the left top seat 64, it enters the brewing space 11 through the left filter screen 66 and comes into contact with the coffee powder to brew. Then the coffee liquid (i.e. the brewed liquid) flows out from the right brewing nozzle 93 after passing through the right filter screen 95 and the control valve 97, completing the brewing process and flowing out the coffee liquid.

[0071] The left filter 66 and right filter 95 filter out coffee grounds through their tiny pores, allowing the grounds to flow into the brewing space 11. The opening and closing process of the control valve 97 is as follows: under the pressure of hot water, the plug 976 and spring 977 inside the valve body 971 are pushed open, allowing the coffee to flow through; when the coffee is completely discharged, the hot water pressure decreases, the spring 977 rebounds, and the plug 976 re-closes the top cover 975, thus ending the coffee discharge.

[0072] Slag removal process: After brewing, motor 1 drives camshaft 2 to rotate counterclockwise, resetting the left powder tank 5 and right top seat assembly 9 to their initial positions, thus fully opening the brewing space 11. Figure 4 Thus, the residue that was originally trapped in the brewing space 11 by the filters on both sides will naturally fall off, completing the residue removal process. Of course, in other embodiments, such as when the brewing space is jointly constructed by the right powder tank and residue remains in the right powder tank after brewing, the design can be adapted so that the left powder tank moves to the left to reset and open the brewing space, while the right top seat assembly also moves to the left to push the residue off before moving to the right to reset.
