[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 11 As shown, this utility model has two embodiments.

[0029] Example 1:

[0030] Benru Figures 4 to 7 As shown in this embodiment, a detachable crusher blade 5 is detachably connected to a rotating shaft 6. The upper part of the rotating shaft 6 is provided with a hook groove 601. The crusher blade 5 includes a mounting sleeve 51 and a blade 52 connected to the mounting sleeve 51. The mounting sleeve 51 is provided with a mounting hole 5101 that can be detachably connected to the upper part of the rotating shaft 6. The side wall of the mounting hole 5101 is provided with a locking member 53 that can be engaged in the hook groove 601, thereby locking the crusher blade 5 onto the rotating shaft 6. In use, the crusher blade of this invention is first aligned with the upper part of the rotating shaft by aligning the mounting hole on the mounting sleeve, and then engaged in the hook groove by the locking member to lock the crusher blade and the rotating shaft. The crusher blade can be removed by rotating it in the opposite direction of its mounting position, facilitating disassembly and cleaning. Furthermore, the crusher blade does not require positioning at the other end through a cover, making it safer.

[0031] In this embodiment, the hook groove 601 includes a guide groove 6011 and a locking groove 6012. The included angle between the centerline of the guide groove 6011 and the centerline of the locking groove 6012 is α, where 60°≤α≤90°. The locking member 53 can enter the locking groove 6012 along the guide groove 6011, and when the rotating shaft 6 rotates in the first direction, the locking member 53 is always located in the locking groove 6012. This design is simple and low in cost; however, it is only suitable for the rotating shaft 6 to rotate in only one direction. When rotating in the other direction, it may loosen.

[0032] In this embodiment, the centerline of the guide groove 6011 is parallel to the axis of the rotating shaft 6, which facilitates the installation of the crushing blade onto the rotating shaft 6.

[0033] Example 2:

[0034] like Figures 8 to 11 As shown, in this embodiment, the hook groove 601 includes a second guide groove 6013, a third guide groove 6014, and an anti-detachment groove 6015. The locking member 53 can pass through the second guide groove 6013 and the third guide groove 6014 and then enter the locking groove 6012. An elastic member 7 is provided between the breaker 5 and the rotating shaft 6 to keep the locking member 53 always within the locking groove 6012. During installation, the mounting sleeve 51 needs to be pressed down to allow the locking member 53 to enter the root of the second guide groove 6013. Then, the mounting sleeve is rotated to allow the locking member 53 to enter the locking groove 6012 along the third guide groove 6014. Finally, the elastic member 7 keeps the locking member 53 always within the locking groove 6012. Pressing the mounting sleeve and then rotating it in the opposite direction allows the breaker to be removed. Compared to Embodiment 1, the structure is more complex but safer, and the connection can be kept stable regardless of the direction of rotation of the rotating shaft.

[0035] In this embodiment, the centerline of the guide groove 6011 is parallel to the axis of the rotating shaft 6, which facilitates the assembly and disassembly of the crusher blade.

[0036] In this embodiment, a slider 71 is slidably connected to the upper part of the rotating shaft 6. A limiting member 72 is provided on the upper part of the rotating shaft 6 to limit the sliding stroke of the slider 71. The elastic member 7 is a spring disposed between the slider 71 and the upper part of the rotating shaft 6, and the spring is sleeved on the limiting member 72. The spring drives the slider to separate the mounting sleeve and the rotating shaft, thereby ensuring that the locking member 53 is always located in the locking groove 6012.

[0037] In this embodiment, a blind hole 6016 for accommodating the spring is provided on the upper part of the rotating shaft 6 to prevent dirt from accumulating.

[0038] likeFigures 1 to 4 The pet food processor of the embodiment shown comprises a main machine 1, an inner barrel 2, a cover 3, a driving motor 4 and a crushing knife 5 as described above, the main machine 1 is provided with a heating cavity 101 with an opening at the upper end, the main machine 1 is provided with a heating assembly 11 for heating the heating cavity 101, the inner barrel 2 is detachably connected in the heating cavity 101, the cover 3 is detachably connected at the opening of the heating cavity 101 of the main machine 1, and when the cover 3 is opened, the inner barrel 2 can be taken out from the heating cavity 101, the inner barrel 2 is provided with a working cavity 201 with an opening at the upper end, the crushing knife 5 is located in the working cavity 201, the bottom of the inner barrel 2 is provided with the rotating shaft 6 as described above, the crushing knife 5 is detachably connected on the rotating shaft 6, and the output shaft of the driving motor 4 is in transmission connection with the rotating shaft 6 to drive the crushing knife 5 to rotate. The crushing knife of the pet food processor of the utility model will not fall off during work, and has the advantages of safety and reliability.

[0039] In the embodiment, a lifting handle 21 is arranged on the inner side of the inner barrel 2, two supporting protrusions 22 for supporting the lifting handle 21 are arranged on the inner side of the inner barrel 2, and the supporting protrusions 22 are located on both sides of the lifting handle 21 to avoid the lifting handle 21 from falling into the inner barrel 2 and polluting the lifting handle, which is also not sanitary.

[0040] The above only further illustrates the technical content of the utility model by way of examples, so that the reader can more easily understand, but does not represent that the embodiments of the utility model are limited to this, and any technical extension or re-creation made according to the utility model is also protected by the utility model.
