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 essential component of a coffee machine, its function being to evenly mix hot water and coffee grounds. Coffee brewers are generally divided into upright and horizontal types. Existing upright coffee brewers are generally inconvenient for removing coffee grounds, have a complex structure, and require two motors for control. Existing horizontal coffee brewers rely on water pressure or a cam to compress the coffee grounds, requiring precise pressure control and making operation more complex. Furthermore, current coffee brewers (both upright and horizontal) cannot arbitrarily adjust the amount of coffee grounds within a certain range. Utility Model Content

[0003] To address the above deficiencies, this utility model provides a novel horizontal coffee brewer, including a bracket on which a geared motor is fixedly mounted. The bracket includes a mounting plate on which a drive gear and two driven gears are fixedly mounted. The drive gear is connected to the output end of the geared motor and is also connected to the driven gears. The two driven gears are arranged with opposite rotation directions.

[0004] A feeding chamber is fixedly provided on the inner side of the mounting plate. A movable plunger is slidably sleeved in the feeding chamber. A brewing chamber is abutted at the other end of the feeding chamber. A fixed plunger is slidably sleeved at the other end of the brewing chamber. The other end of the fixed plunger is fixedly connected to the mounting plate.

[0005] The mounting plate consists of two pieces, with a guide rod fixedly disposed between the two mounting plates and connected to two sets of lead screw and nut assemblies. The two sets of lead screw and nut assemblies are respectively connected to two driven gears. Each lead screw and nut assembly includes a rotating rod, one end of which is fixedly sleeved with the driven gear, and the other end is rotatably connected to the mounting plate. A spring is disposed on the rotating rod, one end of which is fixedly connected to the input mechanism of the clutch. The input mechanism of the clutch is connected to the rotating rod via a flat 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, and a nut is connected to the lead screw.

[0006] One of the springs is fixedly connected at one end to the corresponding driven gear, and the other spring is fixedly connected at one end to the mounting plate.

[0007] The movable plunger is slidably connected to the guide rod and fixedly connected to one of the nuts; the brewing chamber is slidably connected to the guide rod and fixedly connected to the other nut.

[0008] Preferably, the outer diameter of the brewing chamber and the feeding chamber are the same, the inner diameter of the movable plunger is the same as that of the feeding chamber, the top of the feeding chamber is provided with a through hole, and a slag discharge mechanism is provided below the position where the feeding chamber and the brewing chamber abut against each other. The through hole at the top of the feeding chamber allows for better connection between the movable plunger and the lead screw, and also serves as a feed inlet, saving equipment space.

[0009] Preferably, the two driven gears mesh with each other, and one of them meshes with the drive gear.

[0010] Preferably, the movable plunger has a plurality of evenly distributed small holes at one end near the feed chamber as a water outlet, and an air nozzle at the other end of the movable plunger, the air nozzle input end of which is connected to the water inlet device of the coffee machine.

[0011] Preferably, the fixed plunger has a plurality of evenly distributed small holes at one end near the feed chamber as drainage outlets, and the other end of the fixed plunger has a discharge outlet that penetrates the mounting plate. A drainage pipe is provided on the lower side inside the fixed plunger, and the drainage pipe is connected to the discharge outlet.

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

[0013] Preferably, both the movable plunger and the brewing chamber are connected to the guide rod and the nut via L-shaped connecting plates, with the two L-shaped connecting plates arranged in an inverted configuration. This inverted configuration prevents the movable plunger from contacting the fixed plunger when the two connecting plates abut against each other.

[0014] Preferably, the length of the feeding chamber is greater than the length of the brewing chamber plus the fixed plunger. When the brewing chamber and the feeding chamber are in contact, coffee powder is poured into the feeding chamber through the through hole between the movable plunger and the brewing chamber.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The horizontal coffee brewer provided by this utility model only requires one motor to control the contact and separation of the brewing chamber and the feeding chamber, which not only reduces equipment costs but also improves equipment operating efficiency.

[0017] 2. By setting two driven gears and two sets of lead screw and nut assemblies, when the brewing chamber and the movable plunger are moved to the center, a clutch is set up so that when the pressure of the tamping reaches the rated value of the clutch, the clutch slips, which reduces the difficulty of precise control of the tamping pressure and ensures that the tamping pressure is constant. No matter how much coffee powder is used, the brewed coffee tastes consistent. Attached Figure Description

Detailed Implementation

[0030] 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.

[0031] like Figures 1 to 11 As shown, this utility model provides a novel horizontal coffee brewer, including a support 1. The support 1 includes two mounting plates 11. A geared motor 2 is fixedly mounted on the support 1. The output end of the geared motor 2 is connected to a drive gear 21, which is mounted on the outside of the mounting plates 11. Two driven gears 22 are also provided on the outside of the mounting plates 11. The two driven gears 22 are meshed with each other vertically, with one driven gear 22 meshing with the drive gear 21. The meshing of the two driven gears 22 allows them to rotate in opposite directions.

[0032] A feeding chamber 3 is fixedly provided on the inner side of the mounting plate 11. A movable plunger 4 is slidably sleeved in the feeding chamber 3. The other end of the feeding chamber 3 abuts against a brewing chamber 6. A fixed plunger 5 is slidably sleeved on the other end of the brewing chamber 6. The other end of the fixed plunger 5 is fixedly connected to the mounting plate 11.

[0033] Four guide rods 7 are fixedly arranged between the two mounting plates 11, and two sets of lead screw and nut assemblies 8 are connected to them. The two sets of lead screw and nut assemblies 8 are respectively fixedly sleeved with two driven gears 22. The lead screw and nut assembly 8 includes a rotating rod 81. One end of the rotating rod 81 is fixedly sleeved with the driven gear 22, and the other end is rotatably connected to the mounting plate 11. A spring 82 is provided on the rotating rod 81. One end of the spring 82 is fixedly connected to the moving gear plate 91 of the clutch 9. The moving gear plate 91 of the clutch 9 is connected to the rotating rod 81 through a flat key 811. A lead screw 83 is fixedly connected to the fixed gear plate 92 of the clutch 9. The lead screw 83 is slidably sleeved on the rotating rod 81. The other end of the lead screw 83 is rotatably connected to the mounting plate 11. A nut 84 is connected to the lead screw 83. The teeth of the moving gear plate 91 and the fixed gear plate 92 are end face teeth.

[0034] One end of one of the springs 82 is fixedly connected to the corresponding driven gear 22, and the other end of the spring 82 is fixedly connected to the mounting plate 11 via a stop block 12.

[0035] The movable plunger 4 is slidably connected to the guide rod 7 and fixedly connected to one of the nuts 84; the brewing chamber 6 is slidably connected to the guide rod 7 and fixedly connected to the other nut 84.

[0036] The brewing chamber 6 and the feeding chamber 3 have the same outer diameter. The top of the feeding chamber 3 is provided with a through hole 31, and a slag discharge mechanism is provided below the position where the feeding chamber 3 abuts against the brewing chamber 6. The through hole 31 at the top of the feeding chamber 3 allows the movable plunger 4 to be better connected to the lead screw 83, and also serves as a feed inlet, saving equipment space.

[0037] The movable plunger 4 has a stainless steel cover at one end near the feed chamber 3. The stainless steel cover has multiple evenly distributed small holes serving as water outlets 41. The other end of the movable plunger 4 is equipped with an air nozzle 42, the input end of which is connected to the water inlet device of the coffee machine. Water is input through the air nozzle 42, then sprayed through the nozzle into the small holes, and finally fed into the brewing chamber 6.

[0038] The fixed plunger 5 is covered with a stainless steel cover at one end near the feed chamber 3. The stainless steel cover has multiple sets of small holes evenly distributed as drain outlets 51. The other end of the fixed plunger 5 is provided with a discharge outlet 52, which penetrates the mounting plate 11. A drain pipe 53 is provided on the lower side inside the fixed plunger 5, and the drain pipe 53 is connected to the discharge outlet 52.

[0039] Both the movable plunger 4 and the brewing chamber 6 are connected to the guide rod 7 and the nut 84 via L-shaped connecting plates 10. The two L-shaped connecting plates 10 are arranged in an inverted manner. The inverted arrangement of the two L-shaped connecting plates 10 can prevent the movable plunger 4 and the fixed plunger 5 from contacting each other when the two connecting plates abut against each other.

[0040] The length of the feeding chamber 3 is greater than the combined length of the brewing chamber 6 and the fixed plunger 5. When the brewing chamber 6 abuts against the feeding chamber 3, the through hole 31 between the movable plunger 4 and the brewing chamber 6 serves as the feeding port.

[0041] The working process of this utility model is as follows: First, the reduction motor 2 is started, which drives the drive gear 21 to rotate. The two driven gears 22 follow the drive gear 21 to rotate, which in turn drives the rotating rod 81 to rotate. The rotating rod 81 then drives the clutch 9 to rotate through the action of the flat key 811. Since the clutch 9 is fixedly connected to the lead screw 83, the lead screw 83 rotates. Because the rotation directions of the two driven gears 22 are opposite, the rotation directions of the two lead screws 83 are also opposite. Therefore, under the action of the nut 84 and the lead screw 83, the brewing chamber 6 and the movable plunger 4 move together towards the center. When the brewing chamber 6 abuts against the feeding chamber 3, the brewing... When the nut 84 corresponding to the brewing chamber 6 cannot move, the corresponding clutch 9 reaches its rated value and begins to slip, pausing the reduction motor 2. Coffee powder is then fed into the feeding chamber 3 through the through hole 31 between the movable plunger 4 and the brewing chamber 6. The reduction motor 2 is then restarted, and the movable plunger 4 continues to move, tamping the coffee powder until the tamping pressure reaches the rated value of the clutch 9 corresponding to the movable plunger 4. At this point, the clutch 9 slips. The travel of the movable plunger 4 depends on the amount of coffee powder, thus ensuring that the tamping pressure is constant. Regardless of the amount of coffee powder, the brewed coffee will have a consistent taste.

[0042] After tamping, turn off the geared motor 2, and the coffee machine starts to take in water. The water enters the brewing chamber 6 through the water outlet 41. The brewed coffee will flow out of the equipment through the discharge outlet 52. After the coffee is filled into the cup, start the geared motor 2 to reverse, so that the brewing chamber 6 is separated from the feeding chamber 3. Until the brewing chamber 6 and the movable plunger 4 return to their original positions, turn off the equipment, and the remaining grounds will fall into the grounds discharge mechanism.
