[0024] Reference Figure 1-6 The utility model provides an embodiment of a household blender with a self-locking mechanism, comprising a placement box 1, a convex edge 2 for fixing is provided at the upper edge of the placement box 1, a card slot 3 for fixing is opened inside the convex edge 2, a fixing slot 4 for locking is opened on one side of the card slot 3, a crushing blade 5 for crushing and stirring is provided inside the placement box 1, and a connecting slot 6 for fixing is provided on the upper end of the crushing blade 5, a box cover 7 for sealing is movably connected to the upper end of the convex edge 2, a fixing block 8 is fixedly connected to the side of the box cover 7 close to the interior of the placement box 1, a guide ring 9 for guiding is fixedly connected to the upper end of the connecting slot 6, a motor 10 for driving is provided inside the guide ring 9, a connecting rod 11 for transmission is provided at the output end of the motor 10, a limiting ring 12 for limiting the motor 10 is movably connected to the inner side of the guide ring 9, a first slider 13 for extrusion is fixedly connected to the lower end of the limiting ring 12, a second slider 14 for fixing the box cover 7 is movably connected to the lower end of the first slider 13

[0025] In an optional embodiment: the convex edge 2 is fixedly connected to the edge of the upper end of the placement box 1 near the outside, and two groups of card slots 3 are provided on both sides of the convex edge 2, and the two groups of card slots 3 are in opposite directions. There are two groups of fixing slots 4, which fix the box cover 7 when it is installed so that it cannot be opened during use.

[0026] In an optional embodiment: the crushing blade 5 is movably connected to the inside of the placement box 1, and its upper end passes through the center of the box cover 7 and is movably connected to the box cover 7. The connecting groove 6 is opened at the upper end of the connecting groove 6. The crushing blade 5 crushes the objects to be crushed when it rotates, and the crushed objects can be stirred at the same time. Because the crushing blade 5 is movably connected to the box cover 7, the stirring rod can be replaced when the objects do not need to be crushed so that only the objects are stirred.

[0027] In an optional embodiment: the box cover 7 is movably connected to the upper end of the convex edge 2, and a notch matching the convex edge 2 is opened on the inner periphery of the box cover 7. Two groups are fixedly connected to the lower end of the box cover 7, and the outer diameter of the box cover 7 matches the size of the card slot 3. When the box cover 7 is closed, the notch matches the convex edge 2, which increases the internal sealing when closed, so that the liquid inside will not seep out during stirring. At the same time, when the box cover 7 is installed, the fixing block 8 needs to be aligned with the card slot 3 opened inside the convex edge 2. When the fixing block 8 enters the card slot 3, the box cover 7 is rotated to further fix the box cover 7.

[0028] In an optional embodiment: the guide ring 9 is fixedly connected to the upper end of the box cover 7, and the inner diameter of the guide ring 9 matches the outer diameter of the motor 10, making it easier to find the connection point when installing the motor 10, thereby improving the convenience during use. At the same time, the guide ring 9 fixes the motor 10 when the motor 10 is working, thereby improving the stability of the motor 10 during operation. The connecting rod 11 is movably connected to the output end of the motor 10, and the size and shape of the connecting rod 11 are consistent with the connecting groove 6, making it easier to connect and disassemble, making it more convenient for home use.

[0029] In an optional embodiment: the limiting ring 12 is movably connected to the upper end of the box cover 7, which is located on the inner side of the guide ring 9 and is initially convex. The first slider 13 is fixedly connected with two groups at the lower end of the limiting ring 12, which is in the shape of an inclined surface, and the first slider 13 is installed inside the box cover 7. When the items are placed inside the placement box 1, the box cover 7 is closed and rotated. Since the initial position of the fixing rod at one end of the second slider 14 is not aligned with the fixing groove 4, the box cover 7 must be rotated when it is closed. After the box cover 7 is rotated into place, the fixing rod will remain aligned with the fixing groove 4. At this time, the motor 10 is installed. When the motor 10 is installed, the limiting ring 12 is pressed to move downward. Since the first slider 13 is fixedly connected to the limiting ring 12, the limiting ring 12 will push the first slider 13 to drop synchronously when it drops. When the first slider 13 descends, the first slider 13 will squeeze the second slider 14, so that the second slider 14 will push the fixing rod out, thereby connecting the fixing rod to the fixing groove 4. After the fixing rod is connected to the fixing groove 4, the box cover 7 is in a fixed state, and it cannot be opened when in use. If the box cover 7 is not rotated when closed or is not rotated into place, the fixing rod cannot be aligned with the fixing groove 4. Therefore, when the motor 10 is installed, the fixing rod will hit the inner side of the convex edge 2 and cannot be extended. When the fixing rod cannot be extended, it means that the second slider 14 cannot move. The inability of the second slider 14 to move will make the first slider 13 unable to descend. When the first slider 13 cannot descend, it will cause the limit ring 12 to bulge at the upper end, so that the connecting rod 11 cannot be connected to the connecting groove 6, thereby failing to drive the crushing blade 5.

[0030] In an optional embodiment: the second slider 14 is movably connected to one side of the first slider 13, and its shape is an inclined surface matching the first slider 13. The end of the second slider 14 close to the outside is fixedly connected to a fixing rod matching the inner diameter of the fixing groove 4. The initial position of the fixing rod is not aligned with the fixing groove 4. The other end of the second slider 14 is fixedly connected to a spring rod 15 for resetting. When the motor 10 is removed after use, the pressure of the limit ring 12 on the second slider 14 is cancelled, so that the second slider 14 will automatically rebound due to the tension of the spring rod 15. When the second slider 14 rebounds, because the first slider 13 and the second slider 14 are connected by an inclined surface, the second slider 14 will squeeze the first slider 13 to rise when it is retracted, thereby resetting the limit ring 12.

[0031] Working principle and process: The user places the items to be stirred inside the placement box 1, closes the box cover 7 and rotates and fixes it, and then places the motor 10 through the guide ring 9. When placing it, the connecting rod 11 needs to be aligned with the connecting groove 6. After the motor 10 is placed, the limit ring 12 will move downward due to the extrusion of the motor 10, causing the first slider 13 to squeeze the second slider 14 to push the fixing rod out, thereby connecting the fixing rod to the fixing groove 4 and fixing the box cover 7. If the box cover 7 is not rotated or rotated into place, the fixing rod cannot be extended, so that the limit ring 12 cannot descend, resulting in the motor 10 being unable to drive the crushing blade 5.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
