[0029] Reference Figure 1-Figure 4 A brewer comprises: a bracket 1, a main body 2, a water inlet sealing plate assembly 3 and a water outlet sealing plate assembly 4. The bracket 1 has a mounting cavity 5; the main body 2 is detachably mounted on the mounting cavity 5, and a brewing cavity 6 is provided in the main body 2. The two ends of the brewing cavity 6 respectively have a water inlet 7 and a water outlet 8, and the side of the brewing cavity has an inlet 9 for coffee powder to enter; the water inlet sealing plate assembly 3 comprises a first sealing plate 10, a water inlet pipeline and a first power source 11, the first sealing plate 10 is movably mounted in the main body 2, the first sealing plate 10 is configured to be able to open and close the water inlet 7, the first power source 11 is mounted on the bracket 1, and the first power source 11 drives the first sealing plate 10 to move; the water outlet sealing plate assembly 4 is mounted on the bracket 1, the water outlet sealing plate assembly 4 has a water outlet channel 12, and the output end of the water outlet sealing plate assembly 4 is configured to be able to slide in the brewing cavity 6. The specific operation principle of the above embodiment is as follows: in the initial state, the first sealing plate 10 closes the water inlet 7, and the coffee powder enters from the feed port 9, and then the output end of the water outlet sealing plate assembly 4 moves into the brewing chamber 6, and cooperates with the first sealing plate 10 to form a closed cavity in the brewing chamber 6, and then high-temperature water is injected through the water inlet pipeline to brew the coffee powder. After brewing, the output end of the water outlet sealing plate assembly 4 continues to slide into the brewing chamber 6 to squeeze the brewed coffee out of the water outlet channel. In the above embodiment, the main body 2 can be moved out independently relative to the bracket 1, and the water outlet sealing plate assembly 4 and the first power source 11 are located on the bracket 1, which can simplify the structure of the main body 2, and at the same time can reduce the size of the main body 2, and facilitate the disassembly and assembly of the main body 2.

[0030] like Figure 3 As shown, in some embodiments, the water inlet sealing plate assembly 3 further includes a driving plate 13 and an intermediate plate 14, one end of the driving plate 13 is rotatably installed in the main body 2 through a first rotating shaft 15, the other end of the driving plate 13 is hinged to one end of the intermediate plate 14, and the other end of the intermediate plate 14 is hinged to the first sealing plate 10 through a second rotating shaft 16, a first guide groove 17 and a second guide groove 18 are provided on the inner side wall of the main body 2, the end of the second rotating shaft 16 is located in the first guide groove 17, a guide column 19 is provided on the first sealing plate 10, and the end of the guide column 19 is located in the second guide groove 18, and the first power source 11 drives the driving plate 13 to move. The driving plate 13, the intermediate plate 14 and the first sealing plate 10 are all located in the main body 2, and the motion trajectory of the first sealing plate 10 can be limited by combining the first guide groove 17 and the second guide groove 18. The setting of the driving plate 13 and the intermediate plate 14 can amplify the power output from the first power source 11, so as to provide sufficient power for the first sealing plate 10. The water inlet sealing plate assembly 3 has a simple and ingenious structure, occupies a small volume, is convenient for being separated from the first power source 11, and operates stably and reliably.

[0031] like Figure 3As shown, in some embodiments, in order to facilitate the discharge of residues, the main body 2 includes an inclined section 20 and a horizontal section 21, the brewing chamber 6 is located in the inclined section 20, the horizontal section 21 is connected to the water inlet 7, and a residue discharge port 22 is provided at the lower part of the connection, and the driving plate 13 and the middle plate 14 are located in the horizontal section 21 away from the end of the residue discharge port 22. After the coffee is brewed, the coffee residues are generally attached to the first sealing plate 10, so that when the first sealing plate 10 opens the water inlet 7, the coffee residues are automatically discharged from the brewing chamber 6 and then leave the main body 2 from the residue discharge port 22. The above-mentioned main body 2 has a reasonable layout, which is conducive to the discharge of residues and simplifies the overall structure.

[0032] like Figure 3 As shown, in some embodiments, the movement trajectory of the first sealing plate 10 can be designed by the shape of the first guide groove 17 and the second guide groove 18. After brewing coffee, the coffee grounds need to be discharged. In order to discharge the coffee grounds smoothly, the first sealing plate 10 needs to be rotated to face the ground. For this purpose, the following design is made in this embodiment: the first guide groove 17 includes a first section 23 and a second section 24 connected to each other, the first section 23 is parallel to the center line of the brewing chamber 6, and the angle between the second section 24 and the first section 23 is set to 90°-135°; the second guide groove 18 includes a third section 25 and a fourth section 26 connected to each other, the third section 25 is parallel to the center line of the brewing chamber 6, and the angle between the second section 24 and the first section 23 is set to 90°-135°; the second guide groove 18 includes a third section 25 and a fourth section 26 connected to each other, and the third section 25 is parallel to the center line of the brewing chamber 6. 6, and the angle between the third section 25 and the fourth section 26 is set to 90°-135°; under the limitation of the above-mentioned first guide groove 17 and the second guide groove 18, the first sealing plate 10 is close to the brewing chamber 6 in a state perpendicular to the center line of the brewing chamber 6. After the first sealing plate 10 is fully opened, the first sealing plate 10 is tilted or vertically downward, so that the coffee grounds on the first sealing plate 10 can be discharged. The design of the first guide groove 17 and the second guide groove 18 can realize the first sealing plate 10 to run according to the set trajectory, which is very convenient. Compared with purely using a connecting rod structure to design the movement trajectory of the first sealing plate 10, it is simpler, saves parts, and saves internal space.

[0033] like Figure 3 and Figure 4As shown, in some embodiments, the first power source 11 includes a first motor and a reducer, a connection hole 28 is provided at one end of the first rotating shaft 15 and the end of the first rotating shaft 15 extends outside the main body 2, the first motor and the reducer are installed on the bracket 1, the first motor is connected to the input end of the reducer, and the output end of the reducer is connected to the connection hole 28 in a transmission manner; the reducer can be reduced by a worm gear or a gear box. An output shaft 27 is connected to the output end of the reducer, and the output shaft 27 is rotatably mounted on the bracket 1, and the output shaft 27 extends into the installation cavity 5. In this way, in the process of installing the main body 2 into the installation cavity 5, the output shaft 27 is synchronously inserted into the connection hole 28, the inner side wall of the connection hole 28 has a protrusion, and the outer side wall of the output shaft 27 has a groove that matches the protrusion, and a transmission connection is formed by the protrusion and the groove. It can be seen from the above that the transmission connection between the first power source 11 and the first sealing plate 10 is very convenient, and the first power source 11 is arranged on the bracket 1 without causing any adverse effects on the drive of the first sealing plate 10, and the structure is very ingenious and practical.

[0034] like Figure 3 and Figure 4 As shown, in some embodiments, the water inlet pipeline includes a first interface 29, a pipeline, and a water inlet channel 30 arranged in the first sealing plate 10. The first interface 29 is arranged on the side wall of the main body 2, and the first interface 29 is connected to the water inlet channel 30 through the pipeline; the bracket 1 is provided with a second interface 31, and the second interface 31 extends into the installation cavity 5. The first interface 29 and the second interface 31 are plug-in connection structures. The connection between the first interface 29 and the second interface 31 can be completed synchronously during the process of installing the main body 2 into the installation cavity 5, which is very convenient. The pipeline is located in the main body 2, that is, the pipeline cannot be observed outside the main body 2, and there is no problem of disordered pipeline layout, which reduces the possibility of pipeline entanglement or scratching.

[0035] like Figure 2As shown, in some embodiments, the water outlet sealing plate assembly 4 includes a second sealing plate 32 and a second power source 33. The second sealing plate 32 is slidably mounted on the bracket 1, the second power source 33 is mounted on the bracket 1, and the output end of the second power source 33 is transmission-connected with the second sealing plate 32; the second sealing plate 32 is provided with a water outlet channel 12. The second power source 33 is configured as a second motor, the bracket 1 is provided with a gear 34 rotatably disposed, the gear 34 is provided with a threaded hole, a screw rod 35 is fixedly connected to one side of the second sealing plate 32, the screw rod 35 is threadedly connected to the threaded hole, and the output end of the second motor is transmission-connected with the gear; a third guide groove is provided on the side wall of the screw rod 35, a limit block is provided on the bracket 1, and the limit block is inserted into the third guide groove, thereby limiting the rotation of the screw rod 35 relative to the bracket 1, so that the screw rod 35 can only slide relative to the bracket 1. The operating principle of the water outlet sealing plate assembly 4 of the above embodiment is as follows: the second motor works, and the second motor drives the gear to rotate through the reduction gear set, and the gear cooperates with the screw 35. Since the screw 35 cannot rotate, the screw 35 can only slide relative to the bracket 1, thereby driving the second sealing plate 32 to slide in the brewing chamber 6. Of course, it can be understood by those skilled in the art that the second power source 33 can also adopt other embodiments, such as a cylinder or an oil cylinder or a linear motor drive.

[0036] like Figure 4 As shown, in some embodiments, a limit plate 36 is rotatably provided on the bracket 1, and the installation cavity 5 has an opening 37 for the main body 2 to enter and exit. The limit plate 36 is configured to open and close the opening 37; a micro switch 38 is also provided on the bracket 1, and the micro switch 38 is used to detect the state of the limit plate 36. When the limit plate 36 is in a position to open the opening 37, the coffee machine cannot work. Only when the limit plate 36 is in a position to close the opening 37, the coffee machine can work normally. By providing the limit plate 36, the main body 2 can be prevented from accidentally sliding out, ensuring the normal operation of the coffee machine.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
