Description

Technical Field

[0001] The invention belongs to the field of coffee machines, in particular to a coffee machine powder distribution component, a powder distributor and a coffee machine with powder distribution. Background Art

[0002] Drinking coffee usually needs to be purchased in stores, but for daily use, you can choose to make it at home. When making coffee with a coffee machine, the coffee powder needs to be put into a cup, but the distribution is uneven when it is directly put into the cup, so people spread the coffee powder. The common ways of spreading the coffee powder are manual spreading and manual spreading with a powder spreader. The operation is relatively complicated and requires high skills from the operator. Generally, the coffee powder spread by unskilled operators is prone to uneven distribution, looseness and inconsistency in the filter cup, which is easy to cause uneven extraction and unbalanced pressure distribution when brewing coffee, resulting in incomplete extraction of the coffee powder and unsatisfactory effect. Summary of the invention

[0003] The purpose of the present invention is to improve the shortcomings of the prior art and provide a coffee machine powder distribution component, a powder distributor and a powder distribution coffee machine, which can achieve uniform powder distribution through mechanical powder distribution.

[0004] The technical solution is as follows:

[0005] The powder distribution assembly of the coffee machine includes a driving mechanism and a powder distribution mechanism, wherein the powder distribution mechanism includes a rotating matching part, a powder distribution part, a powder inlet and a powder outlet, the middle part of the powder distribution part is through-connected, the powder inlet and the powder outlet are respectively located on both sides of the powder distribution part, and the driving mechanism is rotationally matched with the rotating matching part.

[0006] In one of the embodiments, the powder distribution mechanism has a powder guiding channel in the middle, the inlet and the outlet of the powder guiding channel are the powder inlet and the powder outlet, and the powder distribution part is located in the powder guiding channel.

[0007] In one embodiment, the powder distribution part includes a powder distribution rod, and the powder distribution rod spans over the powder guiding channel.

[0008] The powder distributing rods are provided with a plurality of rods, and the plurality of powder distributing rods are transversely arranged on the powder guiding channel

[0009] In one embodiment, four powder distributing rods are provided, one end of the four powder distributing rods converges at the middle of the powder guiding channel, and the other end is connected to the wall of the powder guiding channel.

[0010] In one of the embodiments, the powder distributing rod is provided with a protruding inclined wall, and the inclined wall protrudes beyond the projection range of the powder distributing rod in a top view.

[0011] In one embodiment, the powder distribution mechanism includes a toothed part and a powder distribution part, the toothed part and the powder distribution part are detachably connected, the rotating mating part is configured as a gear tooth and is located on the outer side of the toothed part, and the powder distribution part is located inside the powder distribution part.

[0012] In one of the embodiments, it further comprises a powder mechanism, wherein the powder mechanism is provided with a powder outlet trough, and the powder outlet trough is located above the powder inlet.

[0013] In one of the embodiments, a transmission mechanism is further included, the transmission mechanism includes at least one transmission gear, the driving mechanism is a driving motor, a driving gear is installed on the output shaft of the driving motor, the driving gear is meshed with the transmission gear, and the transmission gear is meshed with the rotating matching part.

[0014] The powder distributor comprises a toothed piece and a powder distributing piece, wherein the toothed piece is provided with a rotating mating portion, and the powder distributing piece is provided with a powder distributing portion, and the toothed piece and the powder distributing piece are fixedly connected to form a powder distributing mechanism, wherein the powder distributing mechanism has a powder inlet and a powder outlet.

[0015] The powder distribution coffee machine comprises a main machine and a coffee machine powder distribution component, wherein the powder distribution mechanism and the driving mechanism are installed on the main machine, and the driving mechanism drives the powder distribution mechanism to rotate.

[0016] The technical solution provided by the present invention has the following advantages and effects:

[0017] 1. When you need to make coffee, turn on the powder distribution mechanism, drive the mechanism to drive the powder distribution mechanism to rotate by rotating the matching part, and the coffee powder enters the powder distribution mechanism through the powder inlet. Then, under the stirring of the powder distribution part, the coffee powder is evenly dispersed and discharged through the powder outlet to complete the powder distribution operation. The powder distribution by machine avoids the uneven manual powder distribution, so the extraction is more uniform and the taste is better.

[0018] 2. There are through holes on two adjacent powder distribution rods. After the coffee powder enters the powder guide channel, it is broken up by the rotation of the powder distribution rod, and then passes through the through hole and is evenly distributed in the receiving container. The inclined wall is protruding, and the volume formed by the trajectory during rotation is larger, so more powder is broken up, and the powder is not easy to pass directly through the gap between the powder distribution rods. In addition, in the process of the coffee powder falling, the powder distribution rod has a larger distribution area in the horizontal direction due to the setting of the inclined wall, so the probability of the coffee powder contacting the powder distribution rod and the inclined wall when falling is greatly increased. When it falls again through the powder distribution part, the area that can fall is more evenly distributed, achieving a better powder distribution effect.

[0019] 3. The toothed part and the powder distribution part are snap-fitted together. When installed in the powder distribution coffee machine, the toothed part needs to be fixed to the coffee machine to cooperate with the drive mechanism to achieve rotation. Therefore, the toothed part cannot be simply disassembled after installation. However, powder is easily accumulated on the powder distribution part during powder distribution, so it needs to be removed. At this time, because the toothed part and the powder distribution part are fixed by snap-fitting, the powder distribution part can be disassembled for cleaning. The gear teeth cooperate with the gears of the drive mechanism, and the gear teeth are on the outside, so that the toothed part itself forms a gear structure, but the middle part is through, which allows coffee powder to enter without affecting rotation.

[0033] like Figures 1 to 4 As shown, the coffee machine powder distribution assembly includes a driving mechanism 10 and a powder distribution mechanism 20, wherein the powder distribution mechanism 20 includes a rotating matching portion 23, a powder distribution portion 24, a powder inlet 25 and a powder outlet 26, wherein the powder distribution portion 24 is through-connected in the middle, and the powder inlet 25 and the powder outlet 26 are respectively located on both sides of the powder distribution portion 24, and the driving mechanism 10 is rotationally matched with the rotating matching portion 23.

[0034] When it is necessary to make coffee, the powder distribution mechanism 20 is turned on and the driving mechanism 10 is driven to rotate the powder distribution mechanism 20 by rotating the matching part 23. The coffee powder enters the powder distribution mechanism 20 through the powder inlet 25. Then, under the stirring of the powder distribution part 24, the coffee powder is evenly dispersed and discharged through the powder outlet 26 to complete the powder distribution operation. The powder distribution by machine avoids the unevenness of manual powder distribution, so the extraction is more uniform and the taste is better.

[0035] The powder distribution mechanism 20 has a powder guide channel in the middle, the inlet and outlet of the powder guide channel are the powder inlet 25 and the powder outlet 26, and the powder distribution part 24 is located in the powder guide channel. The powder guide channel is the channel for coffee powder to enter, and the coffee powder passes through the powder guide channel and then is dispersed in the powder distribution part 24.

[0036] like Figure 3 and Figure 4 As shown, the powder distribution part 24 includes a powder distribution rod 241, which spans the powder guide channel. The powder distribution rod 241 is used to break up the coffee powder and flatten the surface of the coffee powder when rotating, and the powder is discharged through the through position of the powder distribution rod 241 on the powder distribution part 24.

[0037] The powder distributing rods are provided in plurality, and the plurality of powder distributing rods are all transversely arranged on the powder guiding channel.

[0038] Specific as Figure 3 As shown, there are four powder distribution rods 241, one end of the four powder distribution rods 241 converges at the middle of the powder guide channel, and the other end is connected to the wall of the powder guide channel. There are through holes on two adjacent powder distribution rods 241. After the coffee powder enters the powder guide channel, it is scattered under the rotation of the powder distribution rods 241, and then passes through the through holes and is evenly distributed in the receiving container.

[0039] like Figure 3 and Figure 4 As shown, the powder distribution rod 241 is provided with a protruding inclined wall 242, and the inclined wall 242 protrudes beyond the projection range of the powder distribution rod 241 in a top view. The inclined wall 242 is protruding, and the volume formed by the trajectory during rotation is larger, so more powder is crushed, and the powder is not easy to pass directly through the gap between the powder distribution rods 241, and in the process of coffee powder falling, the distribution area of ​​the powder distribution rod 241 in the horizontal direction becomes larger due to the setting of the inclined wall 242, so the probability of contact between the coffee powder passing through the powder distribution rod 241 and the inclined wall 242 when falling is greatly improved, and the area that can fall when falling through the powder distribution part 24 again is more evenly distributed, achieving a better powder distribution effect.

[0040] like Figures 2 to 3 As shown, the powder distribution mechanism 20 includes a toothed member 21 and a powder distribution member 22, and the toothed member 21 and the powder distribution member 22 are detachably connected, and the rotating matching portion 23 is set as a gear tooth and is located on the outer side of the toothed member 21, and the powder distribution portion 24 is located in the powder distribution member 22. The two are connected and matched. When installed in the powder distribution coffee machine, since the toothed member 21 needs to be fixed with the coffee machine to cooperate with the driving mechanism 10 to achieve rotation, the toothed member 21 cannot be simply disassembled after installation. However, powder is easily accumulated on the powder distribution portion 24 during powder distribution, so it needs to be removed. At this time, because the toothed member 21 and the powder distribution member 22 are fixed by a clamping method, the powder distribution member 22 can be disassembled for cleaning. Among them, the gear teeth cooperate with the gears of the driving mechanism 10, and the gear teeth are on the outside, so that the toothed member 21 itself forms a gear structure, but the middle part is through, which allows coffee powder to enter without affecting the rotation.

[0041] like Figure 4As shown, a recessed groove 211 is provided on the toothed member 21, and a raised snap ring 221 is provided on the powder distributing member 22. The toothed member 21 and the powder distributing member 22 are clamped and matched with each other through the recessed groove 211 and the raised snap ring 221, and an interference fit is usually used between the two.

[0042] like Figure 1 and Figure 2 As shown, the coffee powder distributing mechanism 30 is also included. The coffee powder distributing mechanism 30 is provided with a powder outlet trough 31. The powder outlet trough 31 is located above the powder inlet 25. The coffee powder discharged from the powder outlet trough 31 enters the powder distributing mechanism through the powder inlet 25.

[0043] The drive mechanism 10 is a drive motor 11, and a drive gear is mounted on the output shaft of the drive motor 11. The drive gear is meshed with the drive gear 41, and the drive gear 41 is meshed with the rotational matching portion 23. The drive motor 11 drives the drive gear 41 to rotate by using the drive gear on the output shaft, and then drives the powder distributing mechanism 20 to rotate by the matching of the rotational matching portion 23.

[0044] like Figure 2 As shown, the specific transmission mechanism is provided with two transmission gears 41 and a transmission shaft 42, and the powder mechanism 30 is a bean grinding device. At this time, the driving motor 11 drives the first transmission gear 41 to rotate, and the first transmission gear 41 is meshed with the second transmission gear 41. The transmission shaft 42 is circumferentially fixed on the second transmission gear 41, so when the first transmission gear 41 rotates, it drives the second transmission gear 41, and then drives the transmission shaft 42 to rotate, and then the transmission shaft 42 drives the grinding wheel of the bean grinding device to rotate, and the grinding wheel grinds the coffee beans into coffee powder, and finally discharges it through the powder outlet trough 31. At this time, the second transmission gear 41 is meshed with the gear teeth of the toothed member 21, so when the second transmission gear 41 rotates, it drives the powder distribution mechanism 20 to rotate. Therefore, when the machine is turned on, while the bean grinding device is grinding beans, the powder distribution mechanism 20 is also rotating to distribute powder, so that the coffee powder can be evenly spread on the container.

[0045] The specifications of the two transmission gears 41 can be the same or different.

[0046] The powder distribution coffee machine comprises a main machine and a coffee machine powder distribution assembly, the powder distribution mechanism 20 and the driving mechanism 10 are installed on the main machine, and the driving mechanism 10 drives the powder distribution mechanism 20 to rotate. The powder distribution coffee machine can complete the powder distribution operation immediately after grinding the beans because the powder distribution mechanism is set.

[0047] In this embodiment, not only coffee powder but also soybean milk powder can be used. However, for the convenience of description, only coffee powder is used as an example.

[0048] When quoting drawing descriptions, new features that appear are described; in order to avoid repeated quotations of drawings resulting in less concise descriptions, features that have been described clearly will not be quoted in the drawings one by one.

Its purpose is to make the public understand the disclosed content of the present invention more thoroughly and comprehensively, and it does not limit the scope of protection of the present invention.
