Description

Technical Field

[0001] This utility model belongs to the field of coffee machine technology, and in particular relates to a novel horizontal coffee brewer. Background Technology

[0002] The coffee brewer is an important component of a coffee machine. Its function is to extract coffee powder from hot water at high temperature. Some horizontal coffee brewers rely on water pressure or a cam to control the tamping of coffee powder. Most of them control the tamping pressure by controlling the current or pulse of the motor. This pressure is greatly affected by the voltage and current fluctuations of the motor, which can easily lead to uneven tamping and cannot arbitrarily adjust the amount of coffee powder within a wide range. In order to solve these problems, this utility model proposes a new type of horizontal coffee brewer. Utility Model Content

[0003] To address the above deficiencies, this utility model provides a novel horizontal coffee brewer, comprising two mounting plates. One mounting plate has two motor interfaces on its outer surface. A guide rod and two rotating rods are fixedly mounted between the two mounting plates. One end of each rotating rod is connected to the motor interface, and the other end is rotatably connected to the mounting plate. A spring is mounted on each rotating rod, with the two springs positioned opposite each other. A stop is fixedly mounted on one end of each spring, and the spring is fixedly connected to the mounting plate via the stop. The other end of each spring is fixedly connected to the input mechanism of a clutch. The input mechanism of the clutch is connected to the rotating rod via a key. A lead screw is fixedly connected to the output mechanism of the clutch, and the lead screw is slidably sleeved on the rotating rod. The other end of the lead screw is rotatably connected to the mounting plate.

[0004] Another mounting plate has a feeding chamber fixedly provided on its inner side. A movable plunger is slidably sleeved in the feeding chamber. The movable plunger is slidably connected to the guide rod and to one of the lead screws.

[0005] A fixed plunger assembly is slidably connected to one of the mounting plates. The fixed plunger assembly is connected to the motor interface corresponding to the movable plunger via a synchronous belt. A brewing chamber is slidably sleeved on the fixed plunger assembly.

[0006] Preferably, the fixed plunger assembly includes a fixed plunger slidably connected to the mounting plate. The fixed plunger includes bearings at both ends and a bushing in the middle. A drive shaft is slidably connected inside the fixed plunger. The drive shaft is hollow inside. One end of the drive shaft is provided with a water outlet, which is fixedly located on the outside of the mounting plate. The other end of the drive shaft is provided with the bearing, and a filter screen is fixedly mounted on the bearing. A drive wheel is fixedly mounted on the drive shaft, and a synchronous belt is provided on the drive wheel. The other end of the synchronous belt is connected to the motor interface corresponding to the movable plunger. The fixed plunger and the filter screen are slidably fitted with the brewing chamber. When the brewing chamber moves, the drive shaft does not move, so the bearing and the filter screen also do not move and will move from one end of the brewing chamber to the other end.

[0007] Preferably, a handle is fixedly provided on the outer surface of another mounting plate to facilitate the disassembly and installation of the brewer.

[0008] Preferably, a protective sleeve is provided on the inner side of one of the mounting plates, and the fixed plunger is slidably connected to the protective sleeve. The protective sleeve can reduce the wear on the mounting plate when the fixed plunger rotates.

[0010] Preferably, a connecting plate is fixedly connected to both the movable plunger and the brewing chamber, the connecting plate is slidably connected to the guide rod, a nut is fixedly provided on the connecting plate, and the nut is slidably connected to the lead screw.

[0011] Preferably, the movable plunger is provided with a water inlet pipe, and one end of the water inlet pipe near the mounting plate is provided with a water inlet, and the other end is connected to the filter screen. A detachable sealing ring is provided on the outside of the filter screen. The sealing ring is slidably connected to the brewing chamber. The sealing ring can prevent coffee liquid from flowing out, and the detachable design makes it convenient for cleaning and replacement.

[0012] Preferably, the input mechanism of the clutch is a moving gear plate, the output mechanism is a fixed gear plate, and the teeth on the moving gear plate and the fixed gear plate are end face teeth.

[0013] Preferably, the outer diameter of the brewing chamber and the feeding chamber are the same, and the inner diameter of the movable plunger is the same as that of the feeding chamber and the brewing chamber.

[0014] Preferably, the top of the feeding chamber is open, and a slag discharge device is provided below the feeding chamber and the fixed plunger assembly. When the feeding chamber and the brewing chamber come into contact, coffee powder is poured in from the top of the feeding chamber. After the brewing chamber and the movable plunger are completely separated, the coffee grounds will be carried out by the fixed plunger assembly and fall into the slag discharge device.

[0015] The novel horizontal coffee brewer provided by this utility model has the following beneficial effects:

[0016] 1. The brewer of this utility model, by setting up a drive shaft, drive wheel, synchronous belt and bearing, can drive the filter screen on the drive shaft to rotate while the brewer is tamping the coffee powder, thereby driving the coffee powder to fill the space surrounded by the fixed plunger assembly, the movable plunger and the brewing chamber evenly, preventing the coffee powder from accumulating at the bottom of the brewer and the movable plunger, and improving the uniformity and quality of tamping.

[0017] 2. The brewer of this utility model is designed with a handle for easy disassembly and installation. It is also designed with a motor interface to connect to the motor built into the coffee machine, which allows for safe cleaning and prevents liquid from falling into the equipment during operation, thus avoiding damage to the motor and extending the service life of the brewer.

[0018] 3. The movable plunger and brewing chamber of this utility model are each connected to a separate motor interface, which allows the two motors to be controlled independently. This solves the problem of motor overload caused by setting up a single motor to control the movement of both the movable plunger and the brewing chamber at the same time, and improves the safety of using the brewing chamber.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0027] This utility model provides a novel horizontal coffee brewer, such as Figure 1-2 As shown, the device includes a bracket, which comprises two mounting plates 1. One mounting plate 1 has two motor interfaces 4 on its outer surface for connection to the motor inside the coffee machine. The other mounting plate 1 has a handle 22 on its outer surface for easy disassembly and installation of the brewer. The motor interfaces 4 are also connected to the motor inside the coffee machine. Four guide rods 2 and two rotating rods 3 are fixedly mounted between the two mounting plates 1. One end of each rotating rod 3 is connected to the motor interface 4, and the other end is rotatably connected to the mounting plate 1. Springs 5 ​​are mounted on the rotating rods 3. With the orientations reversed, one end of the spring 5 is fixedly equipped with a stop block 13, and the spring 5 is fixedly connected to the mounting plate 1 through the stop block 13. The other end of the spring 5 is fixedly connected to the input mechanism of the clutch 6. The input mechanism of the clutch 6 is connected to the rotating rod 3 through a flat key. The output mechanism of the clutch 6 is fixedly connected with a lead screw 7, which is slidably sleeved on the rotating rod 3. The other end of the lead screw 7 is rotatably connected to the mounting plate 1. The input mechanism of the clutch 6 is a moving gear plate, and the output mechanism is a fixed gear plate. The teeth on the moving gear plate and the fixed gear plate are end face teeth.

[0028] Another mounting plate 1 has a feed chamber 9 fixedly installed on its inner side. The top of the feed chamber 9 is open. A movable plunger 10 is slidably fitted inside the feed chamber 9. The inner diameter of the movable plunger 10 is the same as the inner diameter of the feed chamber 9. This prevents coffee liquid from flowing into the feed chamber 9 during coffee brewing. A water inlet pipe is installed inside the movable plunger 10. One end of the water inlet pipe near the mounting plate 1 has a water inlet 11, which can be connected to the water tank of the coffee machine to provide the required water for the brewer. The other end of the water inlet pipe is connected to... A filter screen 12 is connected, and a removable sealing ring 24 is provided on the outside of the filter screen 12 to prevent coffee liquid from flowing out. A connecting plate 20 is fixedly connected to the movable plunger 10. The connecting plate 20 is slidably connected to four guide rods 2. A nut 8 is fixedly provided on the connecting plate 20. The nut 8 is slidably connected to one of the lead rods 7. The guide rods 2 provide a guiding function. After the motor corresponding to the movable plunger 10 is turned on, the connecting plate 20 can only move and will not rotate under the action of the guide rods 2, lead rods 7 and nuts 8.

[0029] One of the mounting plates 1 has a protective sleeve 23 on its inner side, and a fixed plunger assembly is slidably connected inside the protective sleeve 23, such as... Figure 5-6As shown, the fixed plunger assembly includes a fixed plunger that is slidably connected to the protective sleeve 23. The fixed plunger includes bearings 19 at both ends and a bushing 21 in the middle. A drive shaft 18 is slidably connected inside the fixed plunger. The drive shaft 18 is hollow inside. One end of the drive shaft 18 is provided with a water outlet 14, which is located on the outside of the mounting plate 1. The other end of the drive shaft 18 is provided with a bearing 19, on which a filter screen 12 is fixedly mounted. A drive wheel 15 and the fixed plunger are fixedly mounted on the drive shaft 18. A synchronous belt 16 is provided on the drive wheel 15, and the other end of the synchronous belt 16 is connected to the motor interface 4 corresponding to the connecting plate 20. When the movable plunger 10 moves, it can drive the fixed plunger assembly to rotate. A brewing chamber 17 is slidably sleeved on the fixed plunger and the filter screen 12 for brewing. The brewing chamber 17 is slidably connected to the filter screen 12, the sealing ring 24, and the bearing 19. A connecting plate 20 is fixedly connected to the brewing chamber 17. The connecting plate 20 is slidably connected to the four guide rods 2. The nut 8 is fixedly installed on the connecting plate 20. The nut 8 is slidably connected to another lead screw 7. When the connecting plate 20 moves the brewing chamber 17, the transmission shaft 18 does not move. Therefore, the bearing 19 and the filter screen 12 also do not move and move from one end of the brewing chamber 17 to the other end. The sealing ring 24 can prevent water from flowing out of the brewing chamber 17. The outer diameter of the brewing chamber 17 and the feeding chamber 9 are the same. The inner diameter of the movable plunger 10 is the same as that of the feeding chamber 9 and the brewing chamber 17. When the brewing chamber 17 and the feeding chamber 9 are in contact, the coffee powder is poured in from the space left in the feeding chamber 9 between the brewing chamber 17 and the movable plunger 10.

[0030] Both the fixed plunger and the movable plunger 10 have stainless steel screens 12, which are provided with multiple sets of evenly distributed small holes to filter out coffee grounds that have not been fully brewed.

[0031] The specific workflow of this embodiment is as follows: First, the motor corresponding to the brewing chamber 17 can be started on the control panel of the coffee machine. The motor drives the rotating rod 3 and the lead screw 7 to rotate. Under the action of the guide rod 2, the lead screw 7, and the nut 8, the brewing chamber 17 is moved towards the feeding chamber 9. At this time, the bearing 19 and the filter screen 12 remain stationary and will move from one end of the brewing chamber 17 to the other end until the brewing chamber 17 comes into contact with the feeding chamber 9. Then, the clutch 6 slips, pausing the motor. Figure 3 As shown, coffee powder is poured into the feeding chamber 9 space between the brewing chamber 17 and the movable plunger 10. Then, the motor corresponding to the movable plunger 10 is started. Under the action of the guide rod 2 and the lead screw 7, the movable plunger 10 moves with the coffee powder 10 towards the brewing chamber 17. At this time, because the synchronous belt 16 connects the motor interface 4 and the transmission wheel 15, the motor drives the rotating rod 3, the lead screw 7, and the transmission wheel 15 to rotate, which in turn drives the transmission shaft 18, the bearing 19, and the filter screen 12 on the brewing chamber 17 to rotate, ensuring the uniformity of the tamping. When the movable plunger 10 and the coffee powder come into contact with the filter screen 12 on the brewing chamber 17, as... Figure 4As shown, the tamping process begins, and the coffee powder is tamped until the tamping pressure reaches the rated value of the clutch 6 corresponding to the movable plunger 10. At this point, the clutch 6 slips, and the travel of the movable plunger 10 depends on the amount of coffee powder. Therefore, the tamping pressure can be kept constant, ensuring that the brewed coffee has a consistent taste regardless of the amount of coffee powder.

[0032] After tamping the coffee grounds, pause the motor and start the water inlet program. Water enters the brewing chamber 17 from the inlet 11. The brewed coffee flows from the filter 12 on the brewing chamber 17 into the drive shaft 18, and finally flows from the outlet 14 to the water receiving port of the coffee machine. After the coffee is filled into the cup, start both motors in reverse so that the brewing chamber 17 and the movable plunger 10 return to their original positions. The remaining coffee grounds are pushed out of the brewing chamber 17 by the bearing 19 and the filter 12 on the brewing chamber 17 and fall into the grounds discharge device below.
