[0044] The invention provides a mixer.

[0045] In the embodiment of the present invention, refer to Figures 1 to 4The mixer comprises a base 10, a mixing knife group 20 and a locking member 30; the base 10 is provided with a groove 10a; one end of the mixing knife group 20 is penetrated through the base 10 and extends into the groove 10a; and the outer wall of the end of the mixing knife group 20 extending into the groove 10a is provided with at least two protrusions 20a, and the two protrusions 20a are arranged at intervals; the locking member 30 is movably arranged in the groove 10a and is detachably connected to the end of the mixing knife group 20 extending into the groove 10a; the locking member 30 is provided with a locking cavity 30a communicating with the groove 10a, and the locking member 30 A plurality of assembly blocks 301 are provided surrounding the locking cavity 30a, and two adjacent assembly blocks 301 cooperate to form a through groove 30b connected to the locking cavity 30a, and a first inclined surface 301a is provided on the side of each assembly block 301 facing the through groove 30b; the side of the assembly block 301 facing away from the locking cavity 30a is defined as a positioning surface 301b; wherein, the locking member 30 rotates relative to the mixing knife group 20 so that the protrusion 20a moves along the first inclined surface 301a from the through groove to the positioning surface 301b, and is clamped between the positioning surface 301b and the bottom wall of the groove 10a.

[0046] In this embodiment, the blender also includes a pot body, which has an inner cavity, and a base 10 is arranged at the bottom of the pot body; the outer wall of the part of the mixing knife group located in the groove 10a is convexly provided with at least two protrusions 20a, and the two protrusions 20a are arranged at intervals; the side of the assembly block 301 adjacent to the bottom wall of the groove 10a is the top side, that is, the positioning surface; the side of the assembly block 301 away from the bottom wall of the groove 10a is the bottom side. When the user drives the locking member 30 to rotate counterclockwise at one end away from the bottom wall of the groove 10a, the locking member 30 drives the assembly block 301 to rotate, and the protrusion 20a of the mixing knife group 20 moves from the groove 30b along the first inclined surface 301a of the assembly block 301 to the positioning surface 301b, that is, the protrusion 20a rises from the bottom side of the assembly block 301 along the first inclined surface 301a of the assembly block 301 to the positioning surface 301b, so that the protrusion 20a can be limited between the positioning surface 301b of the assembly block 301 and the bottom wall of the groove 10a of the base 10, thereby achieving the locking of the mixing knife group 20 in the groove 10a of the base 10. The user drives the locking member 30 to rotate clockwise at one end of the groove bottom wall away from the groove 10a. When the locking member 30 drives the assembly block 301 to rotate, the protrusion 20a of the mixing knife group 20 moves from the positioning surface through the groove 30b to the bottom side of the assembly block 301, so that the protrusion 20a is reset to the bottom side of the assembly block 301, and then the mixing knife group 20 can be detached from the notch of the groove 10a of the base 10, thereby realizing the detachment of the mixing knife group 20 from the base 10.

[0047] The mixer of the technical solution of the present invention comprises a base 10, a mixing knife group 20 and a locking member 30; wherein one end of the mixing knife group 20 is inserted into the base 10 and extends into the groove 10a; and the outer wall of one end of the mixing knife group 20 is provided with at least two protrusions 20a arranged at intervals; the locking member 30 is movably inserted into the groove 10a and is detachably connected to one end of the mixing knife group 20; the locking member 30 is provided with a plurality of assembly blocks 301 surrounding the locking cavity 30a, and two adjacent assembly blocks 301 cooperate to form a through groove 30b connecting the locking cavity 30a, and each assembly block 301 is provided with a first inclined surface 301a on the side facing the through groove 30b; in this way, the user It is only necessary to drive the locking member 30 to rotate, and the locking member 30 drives the assembly block 301 to rotate, so that the protrusion 20a of the mixing knife group 20 moves from the groove 30b along the first inclined surface 301a to the positioning surface 301b, and then the protrusion 20a is limited between the positioning surface 301b and the bottom wall of the groove 10a, so as to achieve the locking of the mixing knife group 20 and the base 10; conversely, the user drives the locking member 30 to rotate in the opposite direction, and the locking member 30 drives the protrusion 20a to return from the positioning surface 301b along the extension direction of the groove 30b to the bottom side of the assembly block 301, so that the user does not need to rotate the base 10 as a whole to achieve the quick disassembly of the mixing knife group 20 and the base 10.

[0048] In one embodiment, referring to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 Each assembly block 301 has a relief notch 301c on one side away from the first slope 301a, and the assembly block 301 has a second slope 301d formed at the relief notch 301c, and the inclination direction of the second slope 301d is consistent with the inclination direction of the first slope 301a.

[0049] In this embodiment, the assembly block 301 is a rectangular block, and a first inclined surface 301a is provided on the right side of the assembly block 301, and a position-avoiding notch 301c is provided on the left side of the assembly block 301. By providing the position-avoiding notch 301c, the distance between two adjacent assembly blocks 301 is made larger; when the user drives the locking member 30 to rotate in the opposite direction, the protrusion 20a of the mixing knife assembly 20 is more likely to move down from the positioning surface 301b along one side of the groove 30b to the bottom side of the assembly block 301, thereby accelerating the disassembly speed. A second inclined surface 301d is formed at the position where the position-avoiding notch 301c is provided, so that the protrusion 20a can slide down along the second inclined surface 301d more easily, further accelerating the disassembly speed. Optionally, the angle between the second inclined surface 301d and the horizontal direction is greater than the angle between the first inclined surface 301a and the horizontal direction; with this arrangement, when the user drives the locking member 30 to rotate counterclockwise, the protrusion 20a of the mixing knife group 20 is more likely to move from the bottom side of the assembly block 301 along the first inclined surface 301a with a greater inclination to the positioning surface 301b.

[0050] In one embodiment, referring to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 The positioning surface 301b is provided with a stopper, which is used to limit the protrusion 20a moving to the positioning surface 301b. In this embodiment, the stopper is arranged opposite to the side of the groove bottom wall of the locking member 30 adjacent to the groove 10a, and the stopper, the assembly block 301 and the locking member 30 are surrounded to form a slide groove; when each protrusion 20a moves from the bottom side of the assembly block 301 along the first inclined surface 301a into the slide groove, the protrusion 20a is limited between the assembly block 301 and the groove bottom wall of the groove 10a. When the user drives the locking member 30 to rotate counterclockwise, the protrusion 20a of the mixing knife group 20 moves from the bottom side of the assembly block 301 along the first inclined surface 301a and the groove 30b into the slide groove. At this time, the two end surfaces of the protrusion 20a in the vertical direction are respectively abutted and restricted by the stop portion and the bottom wall of the groove 10a, making it more difficult for the protrusion 20a to move without driving force, thereby improving the locking tightness of the mixing knife group 20 and the base 10.

[0051] In one embodiment, referring to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 The locking member 30 includes a cylinder 31 and a lever 32; the outer wall of the cylinder 31 is detachably connected to the groove side wall of the groove 10a; the cylinder 31 is provided with a locking cavity 30a; the lever 32 is connected to one end of the cylinder 31 away from the groove bottom wall of the groove 10a.

[0052] In this embodiment, by connecting at one end of the barrel 31 away from the bottom wall of the groove 10a, the user can drive the lock member 30 to rotate more easily by grabbing the lever 32 when driving the lock member 30 to rotate. Optionally, the assembly block 301 can be arranged on a side of the bottom wall of the groove 10a adjacent to the barrel 31. In this way, the distance between the positioning surface 301b of the assembly block 301 and the bottom wall of the groove 10a is reduced, so that when the protrusion 20a moves from the bottom side of the assembly block 301 along the first inclined surface 301a to the positioning surface 301b, the protrusion 20a is not easy to be separated from the positioning surface 301b of the assembly block 301 and the groove 10a, thereby improving the assembly tightness of the mixing knife group 20 and the base 10.

[0053] In one embodiment, referring to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7The outer wall of the cylinder 31 is provided with a plurality of guide grooves 31a arranged at intervals, and the transverse cross-section of the guide groove 31a is in the shape of an arc; the groove side wall of the groove 10a is provided with a plurality of hooks 10b arranged at intervals, and each hook 10b is correspondingly engaged with a guide groove 31a.

[0054] In this embodiment, the guide groove 31a is extended along the circumferential direction of the cylinder 31; the guide groove 31a has a groove top wall arranged opposite to the hook 10b; thus, when the user drives the cylinder 31 to rotate, the cylinder 31 is limited by the groove top wall of the guide groove 31a and the hook 10b, so that the cylinder 31 rotates more stably in the groove 10a of the base 10. In addition, during the locking process of the cylinder 31, the cylinder 31 is limited by the groove top wall of the guide groove 31a and the hook 10b, so that the cylinder 31 is not easy to be separated from the groove of the base 10.

[0055] In one embodiment, referring to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 The lever 32 includes a rod body 321 and a baffle 322; the rod body 321 is connected to the outer wall of the cylinder body 31; the baffle 322 is connected to one end of the rod body 321 away from the cylinder body 31; the baffle 322 is provided with an avoidance notch; when the protrusion 20a is limited between the assembly block 301 and the bottom wall of the groove 10a, the baffle 322 abuts against the first stop block 11b.

[0056] In this embodiment, a baffle 322 is provided at one end of the rod body 321, and the area of ​​the baffle 322 is larger than that of the rod body 321, so that when the user drives the lever 32 to rotate, it is easier to grab the baffle 322, and use the baffle 322 to drive the rod body 321 to rotate, thereby accelerating the disassembly speed of the mixer. An avoidance gap is provided at one end of the baffle 322 connected to the rod body 321, and the avoidance gap is arranged away from the bottom wall of the installation groove 11a; the mixer also includes a drive seat detachably connected to the base 10, and a drive component is provided in the drive seat that is transmission-connected to the mixing knife group 20, so that the drive component drives the mixing knife group 20 to rotate, and then the mixing knife group 20 mixes the food in the pot. A connecting component is also provided in the drive seat, and when the connecting component is connected to the base 10, the avoidance gap prevents the connecting component and the baffle 322 from touching each other, thereby affecting the assembly of the connecting component.

[0057] In one embodiment, referring to Figure 1 , Figure 2 , Figures 5 to 9The cylinder body 31 includes a rotating cylinder 311 and a mounting ring 312. The outer wall of the rotating cylinder 311 is detachably connected to the groove side wall of the groove 10a and is connected to the rod body 321. The rotating cylinder 311 is provided with a locking cavity 30a. The mounting ring 312 is detachably connected to the cavity wall of the locking cavity 30a. The mounting ring 312 is arranged around the locking cavity 30a. The mounting ring 312 has a central hole connected to the locking cavity 30a. The mounting ring 312 is provided with a plurality of the assembly blocks 301 surrounding the central hole.

[0058] In this embodiment, the outer wall of the mounting ring 312 is detachably connected to the cavity wall of the locking cavity 30a. Specifically, a limiting boss is provided on the top of the mounting ring 312. When the mounting ring 312 is detachably inserted into the locking cavity 30a, the limiting boss and the top of the rotating drum 311 define a position. Through the above arrangement, after the cylinder body 31 has been used for a period of time, the multiple assembly blocks 301 of the mounting ring 312 are prone to wear. At this time, the mounting ring 312 connected to the multiple assembly blocks 301 is removed and replaced from the locking cavity 30a of the rotating drum 311, thereby ensuring that the locking member 30 can continuously drive the protrusion 20a of the mixing knife group 20 to move.

[0059] In one embodiment, referring to Figure 1 , Figure 2 , Figures 5 to 9 , the rod body 321 is extended along the groove wall of the groove 10a, and the blocking piece 322 is arranged along the groove bottom wall of the installation groove 11a. Specifically, the contour of the side of the rod body 321 adjacent to the groove wall of the groove 10a is consistent with the groove wall of the groove 10a, and the contour of the side of the blocking piece 322 adjacent to the groove bottom wall of the installation groove 11a is consistent with the groove bottom wall of the installation groove 11a. In this way, when the lever 32 is driven to rotate by the user, the lever 32 is not easy to touch the groove wall of the installation groove 11a and the groove wall of the groove 10a, resulting in the lever 32 rotating unsmoothly. Optionally, the edges of the rod body 321 and the blocking piece 322 are rounded to prevent the rod body 321 and the blocking piece 322 from being easily scratched by the groove wall of the installation groove 11a and the groove wall of the groove 10a when rotating.

A protrusion 20a is provided on the outer wall of the end of the bearing 21 extending into the groove 10a.

[0061] In this embodiment, a gear is provided at one end of the shaft 22 extending into the groove 10a, and the gear is spaced apart from the bearing 21; the drive assembly of the mixer is connected to the gear transmission, and the drive assembly drives the gear to drive the shaft 22 to rotate, and the shaft 22 drives the mixing blade 23 to rotate in the pot body, so that the mixing blade 23 can mix and break the food in the pot body. When the user drives the lever 32 of the lock member 30 to rotate clockwise, the lever 32 drives the barrel 31 to rotate clockwise, so that the barrel 31 drives the protrusion 20a of the bearing 21 to move from the positioning surface 301b of the assembly block 301 along the groove 30b to the bottom side of the assembly block 301, thereby making the entire lock member 30 disengage from the mixing blade assembly 20, and the mixing blade assembly 20 can be loosened relative to the base 10, so that the mixing blade assembly 20 can be detached from the pot body and the base 10.

[0062] In one embodiment, referring to Figure 1 , Figure 3 , Figures 5 to 9 The base 10 includes a body 11 and a chassis 12, the body 11 is provided with a mounting groove 11a, and the chassis 12 is arranged on the bottom wall of the mounting groove 11a; the chassis 12 is provided with a groove 10a; the bottom wall of the mounting groove 11a is provided with a first stop block 11b and a second stop block 11c which are arranged at intervals, and the first stop block 11b and the second stop block 11c are arranged at intervals from the chassis 12; when the protrusion 20a is limited between the assembly block 301 and the bottom wall of the groove 10a, the locking member 30 abuts against the first stop block 11b.

[0063] In this embodiment, the chassis 12 is arranged on the bottom wall of the installation groove 11a, and the extension direction of the groove 10a of the chassis 12 is consistent with the extension direction of the installation groove 11a; the lever 32 is moved from the second stop block 11c to abut against the first stop block 11b, so that when the user drives the lever 32 of the locking member 30 to rotate, the protrusion 20a of the mixing knife group 20 can accurately move from the assembly block 301 of the barrel 31 along the first inclined surface 301a to the first position, thereby accelerating the chassis.

[0064] Optionally, a line connecting the first stop block 11b and the center position of the main body 11 and a line connecting the second stop block 11c and the center position of the main body 11 form an angle of 90 degrees; that is, when the user drives the locking member 30 to rotate counterclockwise, the lever 32 of the locking member 30 can abut against the first stop block 11b after rotating 90 degrees from the position of the second stop block 11c, so that the locking member 30 is switched from an unlocked state to a locked state.

[0065] In one embodiment, referring to Figure 1 , Figure 3 , Figure 4 , Figures 5 to 9The mixer further includes a corrugated spring 40, which is in contact between the bottom wall of the groove 10a and the locking member 30.
