[0023] See Figures 1 to 5 The image shows a dual-head grinder, comprising: a first motor 1 with a first gearbox 11 and a second gearbox 12 respectively at its two ends; a first grinding component 3, which is driven by the first gearbox 11 and used to grind seasonings; a second grinding component 4, which is driven by the second gearbox 12 and used to grind seasonings; it further comprises: a first transmission forward and reverse gear set 5, which is disposed on the first gearbox 11 and used to engage or disengage the transmission connection between the first gearbox 11 and the first grinding component 3; and a second transmission forward and reverse gear set 6, which is disposed on the second gearbox 12 and used to engage or disengage the transmission connection between the second gearbox 12 and the second grinding component 4.

[0024] In this invention, the first motor 1 drives the first grinding component 3 and the second grinding component 4 to grind seasonings via the first gearbox 11 and the second gearbox 12, respectively. This achieves the simultaneous grinding of two seasonings within a limited space. Furthermore, the use of the first motor 1 replaces manual grinding, effectively improving grinding efficiency and making it applicable to various grinding devices. In addition, compared to existing structures, this invention also includes a first transmission forward and reverse gear group 5 capable of engaging / disengaging the transmission connection between the first gearbox 11 and the first grinding component 3, and a second transmission forward and reverse gear group 6 capable of engaging / disengaging the transmission connection between the second gearbox 12 and the second grinding component 4. This ensures that the first motor 1 only controls the first grinding component 3 located below, and when reversed so that the second grinding component 4 faces downwards, it drives the second grinding component 4, making it easier for users to operate and extremely convenient to use.

[0025] The first transmission forward and reverse gear assembly 5 includes: a first rotating shaft head 51 that is drivenly connected to the first grinding assembly 3; a first reverse gear 52 fixedly disposed on the first rotating shaft head 51; a first rotating shaft tail 53 that is drivenly connected to the first gearbox 11; and a first positive gear 54 that is axially slidably disposed in the first rotating shaft tail 53 and can mesh with the first reverse gear 52. The first rotating shaft tail 53 has a first groove 55 formed for axial sliding of the first positive gear 54, and correspondingly, the first positive gear 54 has a first convex ridge 56 formed around its periphery. Here, the first rotating shaft tail 53 also has a first shaft body 57 protruding from the first groove 55. The first shaft body 57 passes sequentially through the first positive gear 54, the first reverse gear 52, and the first rotating shaft head 51, and is fixed by a first washer 58 to further improve the stability of the structure.

[0026] The second transmission forward and reverse gear assembly 6 includes: a second rotating shaft head 61 that is drivenly connected to the second grinding assembly 4; a second reverse gear 62 fixedly disposed on the second rotating shaft head 61; a second rotating shaft tail 63 that is drivenly connected to the second gearbox 12; and a second positive gear 64 that is axially slidably disposed within the second rotating shaft tail 63 and can mesh with the second reverse gear 62. The second rotating shaft tail 63 has a second rib groove 65 formed for axial sliding of the second positive gear 64, and correspondingly, the second positive gear 64 has a second convex rib 66 formed around its periphery. Here, the second rotating shaft tail 63 also has a second shaft body 67 protruding from the second rib groove 65. The second shaft body 67 passes sequentially through the second positive gear 64, the second reverse gear 62, and the second rotating shaft head 61, and is fixed by a second washer 68 to further improve the stability of the structure.

[0027] The support sleeve 13 houses a PCB board 15 for controlling the first motor 1. A push-button switch 16 abuts against the PCB board 15 and protrudes outward through the outer casing 14. When the push-button switch 16 is pressed, the grinder only controls the first grinding component 3 located below the first motor 1. Flipping the grinder causes the second grinding component 4 to flip below the first motor 1, thus driving the second grinding component 4 to operate.

[0028] The first grinding assembly 3 includes: a first accommodating cylinder 31 for holding seasonings, a first drive shaft 32 connected to the first rotating head 51, a first connecting seat 33 fixedly sleeved on the first drive shaft 32, a first toothed ring 34 disposed on the first connecting seat 33, a first grinding tool 35 sleeved on the first drive shaft 32 and used to cooperate with the first toothed ring 34 for grinding, a first spring 36 sleeved on the first drive shaft 32 and used to push the first grinding tool 35, a first inner sleeve 37 fixed on the first connecting seat 33, a first locking cap 38 fixed to the end of the first drive shaft 32, and a first end cap 39 covering the first inner sleeve 37. The first rotating head 51 is formed with a first slot 511 for engaging with the first drive shaft 32. Correspondingly, the first drive shaft 32 is square. The second grinding assembly 4 includes: a second accommodating cylinder 41 for holding seasonings, a second drive shaft 42 connected to the second rotating head 61, a second connecting seat 43 fixedly sleeved on the second drive shaft 42, a second toothed ring 44 disposed on the second connecting seat 43, a second grinding tool 45 sleeved on the second drive shaft 42 and used to cooperate with the second toothed ring 44 for grinding, a second spring 46 sleeved on the second drive shaft 42 and used to push the second grinding tool 45, a second inner bushing 47 fixed on the second connecting seat 43, a second locking cap 48 fixed to the end of the second drive shaft 42, and a second end cap 49 covering the second inner bushing 47. The second rotating head 61 has a second slot formed thereon, and the second drive shaft 42 is square. Here, during use, after placing the seasonings into the first container 31 and the second container 41, pressing the button switch 16 starts the first motor 1, which simultaneously drives the first gearbox 11 and the second gearbox 12. Assuming the second grinding component 4 is located below the first motor 1, the second positive tooth 64 of the second grinding component 4 slides downward under the influence of gravity and meshes with the second negative tooth 62. Furthermore, the second negative tooth 62 and the second rotating shaft head 61 drive the second transmission shaft 42 to rotate, thereby driving the second grinding tool 45 sleeved on the second transmission shaft 42 to rotate and grind. At the same time, the seasonings in the second container 41 also... Under the influence of gravity, the powder falls downwards and passes through the gap between the second grinding tool 45 and the second toothed ring 44, where it is ground into powder and falls into the inner cavity formed by the second inner liner 47 and the second end cap 49, thus completing the grinding of a seasoning. When it is necessary to grind the seasoning in the first accommodating cylinder 31, simply flip the grinder so that the first grinding component 3 is located below the first motor 1, so that the second positive tooth 64 slides downwards under the influence of gravity and disengages from the second negative tooth 62. At the same time, the first positive tooth 54 slides downwards under the influence of gravity and engages with the first negative tooth 52. The remaining steps are the same as those of the second grinding component 4 described above, and will not be repeated here.

[0029] The first motor 1 is surrounded by a support sleeve 13 for supporting it, and the support sleeve 13 is also covered by an outer shell 14.

[0030] One end of the support sleeve 13 is formed with a first rotating locking protrusion 131 for connecting with the first receiving cylinder 31, and correspondingly, the first receiving cylinder 31 is provided with a first rotating locking groove 311; the other end of the support sleeve 13 is formed with a second rotating locking protrusion 132 for connecting with the second receiving cylinder 41, and correspondingly, the second receiving cylinder 41 is provided with a second rotating locking groove 411. Here, the first grinding component 3 can be quickly attached to and detached from the support sleeve 13 using the first rotating locking protrusion 131, effectively improving the practicality of the product.

[0031] In summary, in this invention, the first motor 1 drives the first grinding component 3 and the second grinding component 4 to grind seasonings via the first gearbox 11 and the second gearbox 12 respectively. This achieves the simultaneous grinding of two seasonings within a limited space. Furthermore, the use of the first motor 1 replaces manual grinding, effectively improving grinding efficiency and making it applicable to various grinding devices. In addition, compared to existing structures, this invention also includes a first transmission forward and reverse gear group 5 capable of engaging / disengaging the transmission connection between the first gearbox 11 and the first grinding component 3, and a second transmission forward and reverse gear group 6 capable of engaging / disengaging the transmission connection between the second gearbox 12 and the second grinding component 4. This ensures that the first motor 1 only controls the first grinding component 3 located below, and when reversed so that the second grinding component 4 faces downwards, it drives the second grinding component 4, making it easier for users to operate and extremely convenient to use.
