When assembling the inner liner of this food waste disposer, the pulverizing blade assembly must be manually aligned with the rotating shaft, making it inconvenient to use.

[0003] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0004] In order to solve the problems of the prior art, the utility model provides a grinding device, which is very convenient to assemble and disassemble.

[0005] In order to achieve the above-mentioned purpose, the technical solution applied by the present utility model is as follows:

[0006] A grinding device is provided for use with a food waste disposer. The disposer is equipped with a motor gear set and a coupling. The output end of the motor gear set is connected to the coupling, and a retractable drive shaft is disposed within the coupling. A trash can is also provided, which is detachably mounted on the food waste disposer. The trash can is provided with a grinding screw. The trash can is also provided with a toggle assembly. When the trash can is mounted on the food waste disposer, the toggle assembly drives the drive shaft to extend and connect with the grinding screw. This arrangement allows the drive shaft to be retracted in the initial state, clearing the assembly space for the trash can. Once the trash can is assembled, the toggle assembly controls the drive shaft to extend and connect with the grinding screw, eliminating the need for manual alignment and facilitating trash can assembly.

[0007] According to the above scheme, the coupling includes a shell, the transmission shaft is movably arranged in the shell, a clutch spring is fixed between the first end of the transmission shaft and the inner wall of the shell, the second end of the transmission shaft is arranged corresponding to the opening of the shell, and the second end of the transmission shaft can be extended and retracted inside and outside the shell through the opening; a drive assembly and a lock assembly are provided on the shell, the drive assembly drives the transmission shaft to retract into the shell, the lock assembly is used to lock the drive assembly, and the toggle assembly is used to toggle the lock assembly so that the lock assembly unlocks the drive assembly. When the drive assembly is in the locked state, the transmission shaft retracts into the shell. When the drive assembly is in the unlocked state, the transmission shaft extends out of the shell under the action of the clutch spring. In this way, in the initial state, the drive assembly drives the transmission shaft in a retracted state, the clutch spring is in a compressed state, and the lock assembly locks the drive assembly so that the transmission shaft always remains in a retracted state. When the trash can is installed on the food waste disposer, the toggle assembly drives the lock assembly to operate, so that the lock assembly unlocks the drive assembly. After unlocking, the drive assembly is in an active state, and the rebound force of the clutch spring pushes the transmission shaft out through the opening of the shell and is connected to the grinding screw.

[0008] According to the above solution, the drive assembly includes a button, a pressure plate, and a slider. The lower end of the button passes through the second opening in the housing and is fixedly connected to the upper end of the slider. The lower end of the slider is slidably connected to the upper end of the pressure plate. The lower end of the pressure plate is locked with the drive shaft. The slider can drive the pressure plate to retract the drive shaft into the housing. In this arrangement, when the button is pressed, the button drives the slider downward, and the slider and pressure plate slide and change position, causing the pressure plate to slide relative to the slider and drive the drive shaft to slide back, disengaging the drive shaft from the grinding screw, making it easier to remove the trash can.

[0009] According to the above solution, the lower end of the slider is formed with an inclined sliding groove, and the upper end of the pressure plate is formed with an inclined sliding portion, and the inclined sliding groove and the inclined sliding portion are arranged in cooperation. In this arrangement, when the slider moves downward, the inclined sliding groove and the inclined sliding portion cooperate to push the pressure plate to slide in an offset manner.

[0010] According to the above solution, a bayonet is formed at the lower end of the pressure plate, and an annular groove is formed on the transmission shaft, and the bayonet is engaged with the annular groove. In this arrangement, when the pressure plate slides relative to the slider, the transmission shaft is driven to slide synchronously.

[0011] According to the above solution, a first accommodating groove is formed in the housing, and a first chute and a second chute are formed in the first accommodating groove. The pressure plate is slidably connected to the first chute, and the transmission shaft is slidably connected to the second chute. This arrangement limits the pressure plate and the transmission shaft by the first accommodating groove, and the action of the first chute and the second chute makes the horizontal sliding of the pressure plate and the transmission shaft more stable.

[0012] According to the above solution, the lock assembly includes a lock catch that slides within the housing. A return spring is secured between the first end of the lock catch and the inner wall of the housing. The second end of the lock catch engages the slider. A connecting rod is formed on the lock catch, which passes through opening three of the housing and engages with the toggle assembly. This arrangement causes the lock catch to move toward the slider under the force of the return spring. When the slider is lower than the lock catch, the lock catch locks the slider, thereby keeping the drive shaft in a retracted state.

[0013] According to the above solution, the lock buckle is formed with a second clamping block, and the slider is formed with a first clamping block, and the second clamping block and the first clamping block are engaged and locked. The lower surface of the second clamping block is engaged and locked with the upper surface of the first clamping block. The lower surface of the second clamping block and the upper surface of the first clamping block are flat, while the upper surface of the second clamping block and the lower surface of the first clamping block are inclined. With this arrangement, when the button is pressed to drive the slider downward, the inclined surface of the lower surface of the clamping block cooperates with the inclined surface of the upper surface of the second clamping block, allowing the slider to push the lock buckle open. When the slider is lower than the lock buckle, under the elastic force of the return spring, the lower surface of the second clamping block of the lock buckle cooperates and engages with the upper surface of the first clamping block of the slider, and the lock state is achieved.

[0014] According to the above solution, a second accommodating groove is formed in the housing, and the lock buckle is slidably arranged in the second accommodating groove. In this way, the position of the lock buckle is limited by the second accommodating groove.

[0015] According to the above solution, the toggle assembly includes a toggle lever 1 and a toggle lever 2 provided on the trash can. The toggle lever 2 is used to toggle the connecting rod to unlock the trash can, and the toggle lever 1 is used to toggle the connecting rod to lock the trash can. With this arrangement, when the trash can is assembled on the food waste disposer, the toggle lever 2 rubs against the connecting rod, pushing the connecting rod to drive the lock, causing the lock to disengage from the slider, thereby unlocking the slider. After being unlocked, the slider can move upward, and the transmission shaft extends under the elastic force of the clutch spring to connect with the grinding screw. When the trash can is disassembled, the button is first pressed to drive the slider downward, and the pressure plate slides relative to the slider, driving the transmission shaft to slide back and disengage from the grinding screw. When the trash can is lifted, the toggle lever 1 rubs against the connecting rod, pushing the connecting rod to drive the lock, causing the lock to return to its position, locking the slider, and preventing the transmission shaft from popping out, thereby achieving rapid disassembly of the trash can.

[0016] Beneficial effects of the utility model:

[0017] The utility model is configured such that, in the initial state, the transmission shaft is in a retracted state, avoiding the assembly space of the trash can. When the trash can is assembled, the transmission shaft is controlled to extend and be connected to the grinding screw by toggling the assembly, and there is no need for manual alignment, making the assembly of the trash can convenient.

A retractable transmission shaft 4 is disposed within the coupling 20. A trash can 13 is detachably mounted on the food waste disposer. The trash can 13 is provided with a grinding screw 12. The trash can 13 is provided with a toggle assembly. When the trash can 13 is mounted on the food waste disposer, the toggle assembly drives the transmission shaft 4 to extend and connect with the grinding screw 12. With this arrangement, in the initial state, the transmission shaft 4 is retracted, leaving space for the trash can 13 to be assembled. When the trash can 13 is assembled, the toggle assembly controls the transmission shaft 4 to extend and connect with the grinding screw 12, eliminating the need for manual alignment and facilitating assembly of the trash can 13. During operation, the motor gear set 10 drives the coupling 20 to drive the grinding screw 12 to grind the garbage.

[0029] The trash can 13 includes a drying box 11, a grinding screw 12 is installed in the drying box 11, and a heating element is fixed on the drying box 11, so that the garbage treatment effect is better.

[0030] Furthermore, the coupling 20 includes a shell, and the transmission shaft 4 is movably arranged in the shell, and a clutch spring 5 is fixed between the first end of the transmission shaft 4 and the inner wall of the shell, and the second end of the transmission shaft 4 is arranged corresponding to the opening 25 of the shell, and the second end of the transmission shaft 4 can be extended and retracted in and out of the shell through the opening 25; a driving assembly and a locking assembly are provided on the shell, and the driving assembly drives the transmission shaft 4 to retract into the shell, and the locking assembly is used to lock the driving assembly, and the toggle assembly is used to toggle the lock assembly so that the lock assembly unlocks the driving assembly. When the driving assembly is in the locked state, the transmission shaft 4 retracts into the shell, and when the driving assembly is in the unlocked state, under the action of the clutch spring 5, the transmission shaft 4 extends out of the shell. In this arrangement, in the initial state, the drive assembly drives the transmission shaft 4 in a retracted state, the clutch spring 5 is in a compressed state, and the lock assembly locks the drive assembly so that the transmission shaft 4 always remains in a retracted state. When the trash can 13 is installed on the food waste disposer, the toggle assembly drives the lock assembly to operate, so that the lock assembly unlocks the drive assembly. After unlocking, the drive assembly is in an active state, and the rebound force of the clutch spring 5 pushes the transmission shaft 4 out through the opening 25 of the shell and is connected to the grinding screw 12 for transmission.

[0031] In which, the shell includes a fixedly connected outer shell 1 and a back cover 6, and the back cover 6 is provided with a fourth opening 61. The output end of the motor gear set 10 passes through the fourth opening 61 and is drivingly connected to the first end of the transmission shaft 4, which is used to drive the transmission shaft 4 to rotate. In actual application, when the second end of the transmission shaft 4 is extended and retracted in and out of the shell, the first end of the transmission shaft 4 and the output end of the motor gear set 10 always maintain a transmission state.

[0032] Specifically, the drive assembly includes a button 2, a pressure plate 3, and a slider 7. The lower end of the button 2 passes through the second opening 26 of the housing and is fixedly connected to the upper end of the slider 7. The lower end of the slider 7 is slidably connected to the upper end of the pressure plate 3. The lower end of the pressure plate 3 is engaged with the transmission shaft 4. The slider 7 can drive the pressure plate 3 to retract the transmission shaft 4 into the housing. With this arrangement, when the button 2 is pressed and moved downward, the button 2 drives the slider 7 downward, the slider 7 and the pressure plate 3 slide and change position, the pressure plate 3 slides relative to the slider 7, and the pressure plate 3 drives the transmission shaft 4 to retract into the housing.

[0033] Furthermore, the lower end of the slider 7 is formed with an inclined sliding groove 72, and the upper end of the pressure plate 3 is formed with an inclined sliding portion 31. The inclined sliding groove 72 is arranged in cooperation with the inclined sliding portion 31. In this arrangement, the inclined sliding groove 72 cooperates with the inclined sliding portion 31, and when the slider 7 moves downward, it pushes the pressure plate 3 to slide in an offset manner.

[0034] In actual application, the inclined sliding portion 31 is limited in the inclined sliding groove 72 and can slide relative to the inclined sliding groove 72. When the slider 7 slides up and down, it always remains connected with the pressing plate 3.

[0035] Furthermore, a bayonet 32 ​​is formed at the lower end of the pressure plate 3, and an annular groove 41 is formed on the transmission shaft 4. The bayonet 32 ​​is engaged with the annular groove 41. In this arrangement, when the bayonet 32 ​​and the annular groove 41 are engaged, when the pressure plate 3 slides relative to the slider 7, the transmission shaft 4 is driven to slide synchronously.

[0036] Specifically, a first accommodating groove 21 is formed in the housing, and a first slide groove 23 and a second slide groove 24 are formed in the first accommodating groove 21. The pressure plate 3 is slidably connected to the first slide groove 23, and the transmission shaft 4 is slidably connected to the second slide groove 24. This arrangement limits the pressure plate 3 and the transmission shaft 4 by the first accommodating groove 21, and under the action of the first slide groove 23 and the second slide groove 24, the horizontal sliding of the pressure plate 3 and the transmission shaft 4 is more stable.

[0037] Specifically, the lock assembly includes a lock catch 8 slidably disposed within the housing. A return spring 9 is secured between the first end of the lock catch 8 and the inner wall of the housing. The second end of the lock catch 8 engages the slider 7. A connecting rod 82 is formed on the lock catch 8, which passes through the third opening 27 of the housing and engages with the toggle assembly. This arrangement causes the lock catch 8 to move toward the slider 7 under the elastic force of the return spring 9. When the slider 7 is lower than the lock catch 8, the lock catch 8 locks the slider 7, thereby maintaining the retracted state of the transmission shaft 4.

[0038] The opening three 27 is a strip-shaped hole, which facilitates the connecting rod 82 to slide along the strip-shaped hole when the toggle assembly toggles the connecting rod 82.

[0039] Specifically, the lock catch 8 is formed with a second block 81, and the slider 7 is formed with a first block 71, and the second block 81 and the first block 71 are engaged with each other.
