[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0037] Please also read Figures 1 to 5 The present invention discloses a milling machine 10, which includes a milling machine housing 1, multiple grinding components 2, multiple output gears 3, input gears 4, multiple gear sets 5 and a switching auxiliary member 6. A power chamber a and multiple grinding chambers b are formed in the milling machine housing 1. The multiple grinding components 2 are respectively arranged in the multiple grinding chambers b. The multiple output gears 3 are arranged in the power chamber a and are respectively connected to the multiple grinding components 2. The input gear 4 is arranged in the power chamber a. The multiple gear sets 5 are arranged in the power chamber a. The gear set 5 includes a spacer. A first gear 51 and a second gear 52 are set, and the first gears 51 of the multiple gear sets 5 are respectively meshed and connected with the multiple output gears 3, and the second gears 52 of the multiple gear sets 5 are all meshed and connected with the input gear 4. The first gear 51 and / or the second gear 52 can move axially to engage or disengage the first gear 51 and the second gear 52. The switching auxiliary component 6 is rotatably arranged in the power chamber a, and the rotation of the switching auxiliary component 6 can selectively push the first gear 51 and / or the second gear 52 of one of the gear sets 5 to move axially.

[0038] The grinder of this solution is provided with multiple grinding assemblies 2 and multiple grinding chambers b. By rotating the switching auxiliary part 6 to push the first gear 51 and / or the second gear 52 of one of the gear sets 5 to move axially to a transmission connection, the input gear 4 is transmission-connected to one of the output gears 3, thereby driving one of the grinding assemblies 2 to perform grinding work in one of the grinding chambers b. At the same time, the first gear 51 and the second gear 52 of the other gear sets 5 still maintain a spaced separation state, that is, the input gear 4 is not transmission-connected to the other output gears 3, so the other grinding assemblies 2 do not perform grinding work, and according to different grinding requirements, different grinding assemblies 2 can be switched to grind spices in different grinding chambers b at any time by rotating the switching auxiliary part 6. The clutch structure composed of the switching auxiliary part 6 and the gear set 5 is adopted, and the closing and separation of the clutch structure are realized by rotation, which is easy to operate and has high durability.

[0039] Among them, the first gear 51 and / or the second gear 52 can move axially to the transmission connection, which specifically includes the following three situations: the first gear 51 can move axially to the transmission connection to the second gear 52, the second gear 52 can move axially to the transmission connection to the first gear 51, or, the first gear 51 and the second gear 52 can both move axially to the first gear 51 to the transmission connection to the second gear 52.

[0040] Similarly, the switching auxiliary component 6 is used to rotate to push the first gear 51 and / or the second gear 52 of one group of gear sets 5 to move axially, which specifically includes the following three situations: the switching auxiliary component 6 is used to rotate to push the first gear 51 of one group of gear sets 5 to move axially, the switching auxiliary component 6 is used to rotate to push the second gear 52 of one group of gear sets 5 to move axially, or the switching auxiliary component 6 is used to rotate to push the first gear 51 and the second gear 52 of one group of gear sets 5 to move axially.

[0041] This embodiment is illustrated by taking the example that the second gear 52 can move axially to be transmission-connected to the first gear 51 , and the switching auxiliary component 6 is used to rotate to push the second gear 52 of one of the gear sets 5 to move axially.

[0042] In some embodiments, a gearbox assembly 8 is further provided in the power chamber a, and the input gear 4 is transmission-connected to the gearbox assembly 8, and the gearbox assembly 8 is used to drive the input gear 4 to rotate under the action of an external force.

[0043] Preferably, the power input of the gearbox assembly 8 can be realized through the handheld driver 20. Specifically, the handheld driver 20 is connected to the mill housing 1, and the drive shaft of the handheld driver 20 is connected to the gearbox assembly 8, and the handheld driver 20 is started, and the handheld driver 20 drives the gearbox assembly 8 to rotate, thereby transmitting power to the grinding assembly 2, so that the grinding assembly 2 performs grinding.

[0044] Please also read Figures 4 to 8 In some embodiments, in order to form a power chamber a and multiple grinding chambers b in the mill housing 1, the mill housing 1 includes a bottom shell 11, a grinding chamber shell 12, a middle seat shell 13, a power chamber shell 14 and a top shell 15 arranged from bottom to top, and the bottom shell 11, the grinding chamber shell 12 and the middle seat shell 13 are enclosed to form multiple grinding chambers b, and the middle seat shell 13, the power chamber shell 14 and the top shell 15 are enclosed to form a power chamber a.

[0045] The grinding chamber shell 12 is provided with a partition plate 121, and the partition plate 121 is used to divide the grinding chamber shell 12 into a plurality of grinding chambers b. The grinding assembly 2 extends from the grinding chamber b to the bottom shell 11 and is fixed to the bottom shell 11.

[0046] The power cavity shell 14 includes a left cavity shell 141 and a right cavity shell 142 , and the left cavity shell 141 and the right cavity shell 142 are connected to each other.

[0047] In some embodiments, the grinder 10 further includes a first gear shaft 31 for setting the output gear 3, a second gear shaft 41 for setting the input gear 4, and a third gear shaft 53 for setting the first gear 51 and the second gear 52. The input gear 4 and the second gear shaft 41 are integrally formed.

[0048] In some embodiments, the grinder housing 1 is provided with a plurality of feeding ports 131 respectively connected to the plurality of grinding chambers b, and the grinder housing 1 further comprises a plurality of sealing covers 132, which are respectively used to open or close the plurality of feeding ports 131. With such a configuration, when spices need to be added, the feeding ports 131 can be opened by opening the sealing covers 132, so that spices can be added through the feeding ports 131; when spices do not need to be added, the feeding ports 131 can be closed by closing the sealing covers 132, so that the sealing of the grinding chamber can be ensured during grinding.

[0049] Furthermore, the sealing cover 132 can be turned over on the mill housing 1, that is, the sealing cover 132 can be opened or closed by flipping to open or close the feeding port 131. With such a configuration, on the one hand, the sealing cover 132 can be opened or closed by flipping, which is easy to operate and convenient to use; on the other hand, the sealing cover 132 is turned over and does not need to be disassembled when opened, which can prevent the sealing cover 132 from being separated from the mill housing 1 and lost.

[0050] Further, it can be known from the above that the grinding chamber b is formed by the bottom shell 11, the grinding chamber shell 12 and the middle shell 13 arranged from bottom to top, and preferably, the feeding port 131 is arranged on the middle shell 13, that is, the feeding port 131 is located above the grinding chamber b, so that the spices can be prevented from leaking out along the feeding port 131 during the process of adding spices. Since the feeding port 131 is arranged on the middle shell 13, the sealing cover 132 can also be turned over and arranged on the middle shell 13 accordingly.

[0051] Exemplarily, two grinding chambers b, two groups of grinding components 2, two output gears 3, and two groups of gear sets 5 are formed in the mill housing 1. The two groups of grinding components 2 are respectively arranged in the two grinding chambers b, the two output gears 3 are respectively connected to the two groups of grinding components 2, and the first gears 51 of the two groups of gear sets 5 are respectively connected to the two output gears 3. Correspondingly, the number of the feeding ports 131 and the sealing covers 132 corresponds to the number of the grinding chambers b, which is two. It can be understood that the number of the grinding chambers b, the grinding components 2, the output gears 3, the gear sets 5, the feeding ports 131, and the sealing covers 132 can also be three or more, which is not limited here.

[0052] In some embodiments, in order to enable the first gear 51 and / or the second gear 52 to move axially to a transmission connection, a first ratchet tooth 511 is provided on the end surface of the first gear 51 facing the second gear 52, and a second ratchet tooth 521 is provided on the end surface of the second gear 52 facing the first gear 51. When the first ratchet tooth 511 and the second ratchet tooth 521 are engaged with each other, the first gear 51 and the second gear 52 are transmission connected. That is, when the first gear 51 and the second gear 52 are in a spaced-apart state, the first ratchet tooth 511 and the second ratchet tooth 521 are also in a spaced-apart state. When the first gear 51 and / or the second gear 52 move axially until the first ratchet tooth 511 and the second ratchet tooth 521 are engaged with each other, the first gear 51 and the second gear 52 are transmission connected.

[0053] In some embodiments, in order to separate and reset the first gear 51 and / or the second gear 52 of the previous gear set 5 when the switching auxiliary member 6 is switched to push the first gear 51 and / or the second gear 52 of the next gear set 5 to move axially, the gear set 5 further includes an elastic reset member 54, which is disposed between the first gear 51 and the second gear 52 and is used to reset the first gear 51 and / or the second gear 52. As can be seen from the above, the second gear 52 can move axially until it is transmission-connected to the first gear 51, that is, the elastic reset member 54 is used to reset the second gear 52.

[0054] Exemplarily, the elastic return member 54 is a spring.

[0055] In some embodiments, in order for the switching auxiliary member 6 to rotate to push the first gear 51 and / or the second gear 52 of one of the gear sets 5, a pushing portion 61 is provided on the switching auxiliary member 6, and the switching auxiliary member 6 is used to rotate until the pushing portion 61 faces the first gear 51 and / or the second gear 52 of one of the gear sets 5, so that the pushing portion 61 pushes the first gear 51 and / or the second gear 52 of one of the gear sets 5 to move axially. With such a configuration, when the switching auxiliary member 6 rotates until the pushing portion 61 faces the first gear 51 and / or the second gear 52 of one of the gear sets 5, the pushing portion 61 pushes the first gear 51 and / or the second gear 52 of the corresponding gear set 5. In addition, the first gear 51 and / or the second gear 52 of the other gear sets 5 are not pushed by the pushing portion 61, and the first gear 51 and the second gear 52 on the other gear sets 5 are in a separated state under the action of the elastic reset member 54.

[0056] Furthermore, the switching auxiliary member 6 is in a sheet shape, and the side of the switching auxiliary member 6 facing the gear set 5 is convex toward the gear set 5 to form a push portion 61. The switching auxiliary member 6 in a sheet shape and convex to form a push portion 61 requires less space, which is conducive to the miniaturization design of the grinder.

[0057] Furthermore, the switching auxiliary part 6 is rotatably arranged on the second gear shaft 41. In order to avoid interference between the switching auxiliary part 6 and the first gear shaft 31 and / or the third gear shaft 53, the switching auxiliary part 6 is provided with an escape groove 62 for avoiding the first gear shaft 31 and / or the third gear shaft 53. Specifically, when the first gear shaft 31 needs to be penetrated by the switching auxiliary part 6, the switching auxiliary part 6 is provided with an escape groove 62 for avoiding the first gear shaft 31; when the third gear shaft 53 needs to be penetrated by the switching auxiliary part 6, the switching auxiliary part 6 is provided with an escape groove 62 for avoiding the third gear shaft 53; when both the first gear shaft 31 and the third gear groove need to be penetrated by the switching auxiliary part 6, the switching auxiliary part 6 is provided with an escape groove 62 for avoiding the first gear shaft 31 and the third gear shaft 53. This embodiment takes the example that when both the first gear shaft 31 and the third gear groove need to be penetrated by the switching auxiliary part 6, the switching auxiliary part 6 is provided with an escape groove 62 for avoiding the first gear shaft 31 and the third gear shaft 53.

[0058] Exemplarily, the avoidance groove 62 includes a first avoidance groove 62162 for avoiding the first gear shaft 31 and a second avoidance groove 62262 for avoiding the second gear shaft 41. It is understood that in other preferred embodiments, the design mode of avoiding the first gear shaft 31 and the third gear shaft 53 through the same avoidance groove 62 can also be adopted, which is not limited here.

[0059] In some embodiments, in order to facilitate the rotation of the switching auxiliary member 6 to switch different grinding components 2 for grinding, the grinder 10 further includes a switching knob 7 disposed on the grinder housing 1, the switching knob 7 is connected to the switching auxiliary member 6, and the switching knob 7 is used to drive the switching auxiliary member 6 to rotate relative to the grinder housing 1 under the action of an external force. With this arrangement, the user can rotate the switching auxiliary member 6 to achieve the rotation of the switching auxiliary member 6.

[0060] Furthermore, in order to realize the connection between the switching knob 7 and the switching auxiliary member 6, the switching knob 7 is provided with a card slot 71, and the switching auxiliary member 6 extends outward to form a card block 63 for carding with the card slot 71. In this way, by carding the card block 63 on the switching auxiliary member 6 into the card slot 71 on the switching knob 7, the connection between the switching knob 7 and the switching auxiliary member 6 can be realized, and disassembly and assembly are convenient.

[0061] In some embodiments, in order to grind powders of different coarsenesses into powders of different coarsenesses, the grinding assembly 2 is provided with a coarseness adjustment knob 21, which is rotated in a first direction to produce fine powders, and rotated in a second direction to produce coarse powders, wherein the first direction is one of counterclockwise and clockwise, and the second direction is the other of counterclockwise and clockwise. With such a configuration, when finer powders need to be ground, the coarseness adjustment knob 21 can be rotated in the first direction; when coarser powders need to be ground, the coarseness adjustment knob 21 can be rotated in the second direction, thereby meeting different grinding requirements.

[0062] Exemplarily, the first direction is clockwise, and the second direction is counterclockwise.

[0063] The following is a detailed description of the use of the mill 10:

[0064] First, the sealing cover 132 is flipped open to open the feeding port 131, and then spices are added into the grinding chamber b through the feeding port 131. Then, the sealing cover 132 is flipped to cover the feeding port 131. Then, the handheld driver 20 is connected to the grinder 10, and the power start button of the handheld driver 20 is pressed. The motor in the handheld driver 20 starts to rotate at a high speed, and the gear box assembly 8 in the power chamber a is decelerated and torque is increased according to a certain transmission ratio. At this time, the gear box assembly 8 is transmitted to the input gear 4, and the switching auxiliary part 6 is rotated by rotating the switching knob 7. The switching auxiliary part The rotation of the switching auxiliary member 6 causes the pushing portion 61 of the switching auxiliary member 6 to push the second gear 52 of one of the gear groups 5 to move axially until it is connected to the first gear 51, so that the input gear 4 is connected to one of the output gears 3, and then drives one of the grinding components 2 to perform grinding in one of the grinding chambers b. At the same time, the first gear 51 and the second gear 52 of the other gear groups 5 are kept in a spaced-apart state under the action of the elastic reset member 54, that is, the input gear 4 is not connected to the other output gears 3, so the other grinding components 2 do not perform grinding. When it is necessary to adjust the coarseness of the spices after they are ground into powder, the handheld driver 20 can be paused, and the coarseness adjustment knob 21 on the grinding component 2 can be adjusted. After adjustment, the handheld driver 20 can be started again until the grinding is completed and then stopped.

[0065] The mill 10 provided by the present invention comprises a mill housing 1, multiple grinding components 2, multiple output gears 3, input gears 4, multiple gear sets 5 and a switching auxiliary member 6. A power chamber a and multiple grinding chambers b are formed in the mill housing 1. The multiple grinding components 2 are respectively arranged in the multiple grinding chambers b. The multiple output gears 3 are arranged in the power chamber a and are respectively connected to the multiple grinding components 2. The input gear 4 is arranged in the power chamber a. The multiple gear sets 5 are arranged in the power chamber a. The gear set 5 comprises a first gear 51 and a second gear 52 arranged at intervals. The first gears 51 of the multiple gear sets 5 are respectively meshed and connected with the multiple output gears 3. The second gears 52 of the multiple gear sets 5 are all meshed and connected with the input gear 4. The first gear 51 and / or the second gear 52 can move axially to engage or separate the first gear 51 and the second gear 52. The switching auxiliary member 6 is rotatably arranged in the power chamber a. The first gear 51 and / or the second gear 52 of one of the gear sets 5 can be selectively pushed to move axially through the rotation of the switching auxiliary member 6. The grinder of this solution is provided with multiple groups of grinding components 2 and multiple grinding chambers b. By rotating the switching auxiliary part 6 to push the first gear 51 and / or the second gear 52 of one group of gear groups 5 to move axially to a transmission connection, the input gear 4 is transmission-connected to one of the output gears 3, and then one of the grinding components 2 is driven to perform grinding work in one of the grinding chambers b. At the same time, the first gear 51 and the second gear 52 of the other gear groups 5 are still kept in a separated state, that is, the input gear 4 is not transmission-connected to the other output gears 3, so the other grinding components 2 do not perform grinding work, and according to different grinding requirements, different grinding components 2 can be switched at any time by rotating the switching auxiliary part 6 to grind the spices in different grinding chambers b. The clutch structure composed of the switching auxiliary part 6 and the gear group 5 is adopted, and the closing and separation of the clutch structure are realized by rotation, which is easy to operate and has high durability.
