[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Please refer to Figure 1 The embodiment of the utility model provides a crushing structure of a pet excrement processor, including an inner pot 4, an excrement crushing knife 5, a crushing knife driving device 6 and other components. The various components of this embodiment are described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1 As shown, the top of the inner pot 4 is open, and a ring-shaped crushing knife mounting seat 9 is provided at the bottom of the inner pot 4. The feces crushing knife 5 can be installed inside the inner pot 4 through the crushing knife mounting seat 9. The lower end of the feces crushing knife 5 can pass through the crushing knife mounting seat 9 and be connected to the crushing knife driving device 6 located below the inner pot 4. The crushing knife driving device 6 can drive the feces crushing knife 5 to rotate 360 ​​degrees.

[0025] Specifically, if Figure 3and Figure 4 As shown in Figure 4 , the feces crushing knife 5 may include a blade 51, a rotating shaft 52, a knife seat 53, a lock nut 54 and a gear 55. The rotating shaft 52 is longitudinally and rotatably mounted in the middle of the knife seat 53 through a bearing 56. The blade 51 is locked to the upper end of the rotating shaft 52 through the lock nut 54 and is located above the knife seat 53. The gear 55 is mounted at the lower end of the rotating shaft 52 and is located below the knife seat 53.

[0026] In this embodiment, the two sides of the blade 51 may adopt a structure with different heights, and the height of one side of the blade 51 is higher than that of the other side.

[0027] In order to realize the detachable design of the feces crushing knife 5, as Figures 2 to 5 shown, a plurality of evenly distributed knife seat buckles 531 may be provided on the outer wall of the lower end of the knife seat 53. A snap ring 91 may be provided at the lower end of the central hole of the crushing knife mounting seat 9. A plurality of evenly distributed buckle through holes 92 are provided on the snap ring 91. The knife seat buckle 531 can be snap-connected to the bottom of the snap ring 91 of the crushing knife mounting seat 9.

[0028] Preferably, a knife seat positioning part 532 in the shape of a polygon (such as a hexagon) may also be provided on the outer wall of the knife seat 53. The knife seat positioning part 532 is located above the knife seat buckle 531. The knife seat positioning part 532 can be snap-connected to the top of the snap ring 91 of the crushing knife mounting seat 9.

[0029] When installing the knife, it is necessary to align the knife seat buckle 531 of the knife seat 53 with the buckle through hole 92 of the crushing knife mounting seat 9. At this time, the knife seat 53 can pass through the central hole of the crushing knife mounting seat 9. Then, the knife seat 53 is rotated by a preset angle, and the knife seat buckle 531 can be snap-connected to the bottom of the snap ring 91 of the crushing knife mounting seat 9, and the knife seat positioning part 532 can also be snap-connected to the top of the snap ring 91 of the crushing knife mounting seat 9.

[0030] When removing the knife, only need to rotate the knife seat 53 to align the knife seat buckle 531 of the knife seat 53 with the buckle through hole 92 of the crushing knife mounting seat 9, and then the whole set of feces crushing knife 5 can be pulled out.

[0031] In order to improve the sealing performance of the feces crushing knife 5, as Figure 4 shown, an oil seal 57 may also be provided between the rotating shaft 52 and the knife seat 53. The oil seal 57 is located above and below the bearing 56.

[0032] This embodiment adopts a detachable feces crushing knife, which is convenient for cleaning and replacing the tool.

[0033] As Figure 1 and Figure 3As shown, the shredder drive device 6 includes a motor 61 and a rotating gear seat 62. The output shaft of the motor 61 is connected to the rotating gear seat 62. The motor 61 can drive the rotating gear seat 62 to rotate 360 ​​degrees. The rotating gear seat 62 is provided with a tooth groove 63 that is adapted to the shape of the gear 55. The gear 55 of the feces shredder 5 is detachably installed in the tooth groove 63 of the rotating gear seat 62.

[0034] like Figure 1 As shown, at least one feces blocking block 8 can be further provided on the inner wall of the inner pot 4. The feces blocking block 8 can preferably be arranged in an L shape or a horizontal straight shape. The feces blocking block 8 can block pet feces, making it convenient for the feces crushing knife 5 to cooperate with it to better crush the pet feces, thereby greatly improving the crushing effect.

[0035] During the rotation of the blade 51 , the feces blocking block 8 is just located between the upper and lower spacings of the two side portions of the blade 51 , so that the two side portions of the blade 51 can cooperate with the feces blocking block 8 during the rotation.

[0036] As a further improvement of this embodiment, Figure 1 and Figure 2 As shown, the bottom of the inner pot 4 may be additionally provided with a heating device 7. Specifically, the heating device 7 may include a heating plate 71 and an electric heater 72. The electric heater 72 is installed on both sides of the bottom of the heating plate 71. The top of the heating plate 71 contacts the bottom of the inner pot 4, thereby transferring heat to the inner pot 4. Preferably, the electric heater 72 may be preferably configured as a PTC heater. Of course, in other embodiments, a heating coil may also be used for heating.

[0037] Before the feces are crushed, the heating device can dry the pet feces to a certain extent (such as the drying temperature can be between 75 and 85°C) to reduce the moisture and stickiness of the pet feces, which can reduce the pet feces sticking to the inner wall of the inner pot and the surface of the feces crushing knife, facilitate the cleaning of the inner pot and the feces crushing knife, and facilitate the feces crushing knife to crush the pet feces in the subsequent crushing process, thereby improving the crushing effect.

[0038] It should be noted here that, according to actual needs, in another embodiment, the crushing knife driving device can also be arranged above the inner pot, and accordingly, the feces crushing knife can be connected to the crushing knife driving device through the upper end portion.

[0039] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
