[0027] In the description of the present invention, terms such as "upper", "lower", "left", "right", "front", "backward", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0029] Embodiment 1

[0030] Reference Figures 1 to 7As shown, a kitchen waste treatment device provided in this embodiment includes a shell 1, a treatment barrel 2, a movable grinding disc 3, a pressure grinding disc 4, a screw 5, and a driving component 6. The treatment barrel 2 is arranged in the shell 1, and the screw 5 is rotatably assembled in the treatment barrel 2. The pressure grinding disc 4 is arranged in the treatment barrel 2. The movable grinding disc 3 is located above the pressure grinding disc 4 and has a threaded hole 31. The movable grinding disc 3 is threadedly matched with the screw 5 through the threaded hole 31. The driving component 6 drives the screw 5 to drive the screw 5 to rotate, thereby driving the movable grinding disc 3 to move.

[0031] The operation flow of the kitchen waste treatment of the utility model is as follows: the kitchen waste is placed on the pressure-bearing grinding disc 4, and the movable grinding disc 3 is located above the kitchen waste; the movable grinding disc 3 is in a stationary state, and due to its own weight and stationary inertia and the effect of the screw connection, when the screw 5 starts to rotate, the movable grinding disc 3 starts to move downward through the screw connection formed by the threaded hole 31 and the screw 5; when the movable grinding disc 3 moves downward, it squeezes, crushes, and grinds the kitchen waste on the pressure-bearing grinding disc 4, and continuously applies pressure to the kitchen waste on the pressure-bearing grinding disc 4. The utility model has the advantages of simple mechanical structure setting, simple operation, and high processing efficiency.

[0032] Furthermore, the driving component 6 is provided with a rotation sensor. When the movable grinding disc 3 stops moving downward due to the obstruction of the kitchen waste or the pressure grinding disc 4, the screw 5 stops rotating due to the threaded connection between the movable grinding disc 3 and the screw 5, thereby stopping the driving component 6. At this time, the driving component 6 detects the stall and transmits a signal to the controller of the kitchen waste treatment device, and the controller controls the driving component 6 to stop, ending the grinding process. Specifically, the model, connection relationship and working principle of the rotation sensor and the controller are all prior art and will not be described in detail here.

[0033] Furthermore, a housing upper cover 7 is installed on the housing 1, and a rotatable screw fastener 8 is installed on the housing upper cover 7. When the housing upper cover 7 is covered on the housing 1, the screw fastener 8 is connected with the top of the screw 5 to form a detachable circumferential limit fit, so that the screw fastener 8 and the screw 5 rotate synchronously, and then the movable grinding disc 3 moves on the screw fastener 8 and the screw 5. Through the connection and fit with the screw fastener 8, the lower end of the screw 5 is connected to the driving component 6, and the upper end is connected to the screw fastener 8. Both the upper and lower ends have supports, which can make the screw 5 more stable when rotating; when the movable grinding disc 3 rises to the screw fastener 8, by opening the housing upper cover 7, the screw fastener 8 and the movable grinding disc 3 can be driven to move together, so as to facilitate the removal of the kitchen waste located above the pressure-bearing grinding disc 4 and the cleaning of the internal dirt of the processing barrel 2. Of course, in other embodiments, the structure of the screw fastener 8 may not be adopted. For example, when the shell cover 7 is covered on the shell 1, the upper end of the screw 5 is directly rotatably engaged on the shell cover 7 to support the upper end of the screw 5.

[0034] The screw fastener 8 is connected with the top of the screw 5 to form a detachable circumferential limit fit, and a quadrilateral circumferential limit fit structure can be adopted, such as the screw fastener 8 has a quadrilateral protrusion, and the screw 5 has a quadrilateral recess. Of course, in other embodiments, a quadrilateral circumferential limit fit structure may not be adopted, such as a hexagonal or cross circumferential limit fit structure.

[0035] Furthermore, the pressure-bearing grinding disc 4 is tightly fitted on the screw 5 to rotate with the rotation of the screw 5. The rotating pressure-bearing grinding disc 4 can grind the driven garbage well, so that the kitchen waste above the pressure-bearing grinding disc 4 can continuously adjust the position and shape, which is convenient for extrusion, crushing and grinding. Of course, in other embodiments, other methods can be used to achieve this, for example: the lower grinding disc 4 and the screw 5 are integrally formed; the pressure-bearing grinding disc 4 can also be fixed at other positions without rotating with the screw 5.

[0036] Furthermore, a receiving cavity 21 is formed between the bottom of the processing barrel 2 and the pressure grinding disc 4 for receiving kitchen waste residues and liquids that fall from the gap between the processing barrel 2 and the pressure grinding disc 4 after processing, so as to facilitate subsequent kitchen waste processing.

[0037] Furthermore, a first heating component 9 is provided outside the processing barrel 2, and the first heating component 9 is in thermal contact with the processing barrel 2, so that the internal temperature of the processing barrel 2 is increased to evaporate moisture in the kitchen waste and heat grease, thereby facilitating further squeezing, crushing, grinding and processing.

[0038] Furthermore, the processing barrel 2 is externally provided with a heat-insulating outer reflective barrel 10, and the outer reflective barrel 10 can retain the heat generated by the heating component 9, so that most of the heat is transferred to the inside of the processing barrel 2, thereby improving the heating efficiency.

[0039] Of course, in other embodiments, other methods may be used to process the squeezed liquid, such as adding a drain port to discharge the liquid.

[0040] Furthermore, a protrusion 22 is provided at the center of the bottom of the processing barrel 2, and the screw 5 is provided with a recessed portion 51. The recessed portion 51 of the screw 5 covers the protrusion 22 to prevent kitchen waste residues, liquid kitchen waste, etc. from flowing into the gap between the processing barrel 3 and the screw 6; by providing the protrusion 22, kitchen waste residues, liquid kitchen waste, etc. are prevented from flowing into the driving component 6 and causing damage to the driving component 6.

[0041] Furthermore, the protrusion 22 has a central through hole 23, and the driving component 6 is assembled in the housing 1. The driving component 6 includes a rotary driver 61 and a transmission component 62. The rotary driver 61 drives and connects the transmission component 62. The transmission component 62 has a transmission shaft 621. The transmission shaft 621 is assembled in the central through hole 23 of the protrusion 22 and is connected with the bottom of the screw 5 to form a detachable circumferential limit fit. Therefore, the screw 5 can be disassembled and separated from the transmission shaft 621, which is convenient for disassembling and cleaning the screw 5 and cleaning other internal components of the processing barrel 2. The transmission shaft 621 is connected with the bottom of the screw 5 to form a detachable circumferential limit fit, and a quadrilateral circumferential limit fit structure can be adopted, such as the transmission shaft 621 has a quadrilateral protrusion, and the bottom of the screw 5 has a quadrilateral recess. Of course, in other embodiments, the quadrilateral circumferential limiting matching structure may not be used, such as a hexagonal or cross circumferential limiting matching structure.

[0042] Furthermore, the transmission component 62 also includes a clutch male head 622 and a clutch female head 623. The central through hole 23 is provided with a bearing component 24. The transmission shaft 621 is inserted and fixed in the bearing component 24. The clutch male head 622 is connected to the transmission shaft 621 by bolts and installed in the central through hole 23. The clutch male head 622 and the clutch female head 623 form a detachable circumferential limit fit, and the clutch female head 623 forms a transmission fit with the rotary driver 61. Therefore, when the clutch male head 622 and the clutch female head 623 are disassembled and separated, the processing barrel 2 can be separated from the shell 1 and lifted, which is convenient for subsequent kitchen waste processing. The clutch male head 622 and the clutch female head 623 are connected to form a detachable circumferential limit fit, and a quadrilateral circumferential limit fit structure can be adopted, such as the clutch male head 622 has a quadrilateral protrusion, and the top of the clutch female head 623 has a quadrilateral recess. Of course, in other embodiments, a quadrilateral circumferential limit fit structure may not be adopted, such as a hexagonal or cross circumferential limit fit structure.

[0043] Specifically, the manner in which the clutch female head 623 and the rotary driver 61 form a transmission cooperation is prior art. In this embodiment, the transmission component 62 also includes a gear set 624, and the gear set 624 transmits the rotational power generated by the drive motor 61 to the clutch female head 623; the drive motor 61 can also be used to directly cooperate with the clutch female head 623 to transmit power.

[0044] Specifically, the movable grinding disc 3 and the pressure grinding disc 4 are both disc-shaped with protruding peripheries and recessed central portions, and the recessed central portions of the movable grinding disc 3 and the pressure grinding disc 4 are arranged opposite to each other. Thus, the kitchen waste can stay between the movable grinding disc 3 and the pressure grinding disc 4 and be fully ground.

[0047] Specifically, the screw 5 and the receiving grinding disc 4 both have cavities inside, and the second heating component is arranged in the cavity. More specifically, one of the electrical connection methods of the second heating component is: an integrated circuit is provided on the housing upper cover 7, and an electrode is provided on the screw fastener 8. When the screw fastener 8 is in contact with the screw 5, the second heating component can form electrical contact with the electrode on the screw fastener 8, thereby realizing power supply of the second heating component. Of course, in other embodiments, the electrical connection method of the second heating component is not limited to this.

[0048] Meanwhile, in other embodiments, the second heating component may also be separately disposed in the screw 5 or separately disposed in the receiving grinding disc 4 .
