[0039] See also Figure 1 As shown, the blender of the embodiment of the present application comprises a main machine 1 and a blending device 2 assembled on the main machine 1. In the illustrated embodiment, the blending device 2 is detachably assembled on the main machine 1, but the present application is not limited thereto. In another embodiment, the blending device 2 and the main machine 1 are not detachable.

[0040] The host 1 includes a housing 10 and a motor assembly (not shown) located in the housing 10. The housing 10 includes a gripping portion 101 for an operator to hold and a mounting portion 102 extending from the gripping portion 101. The stirring device 2 is detachably mounted on the mounting portion 102, for example, by means of a buckle or a thread for assembly and positioning.

[0041] See also Figures 2 to 4 As shown, the stirring device 2 includes a shell 20, a stirring blade assembly 21 and a protective cover 22 assembled on the shell 20. The shell 20 includes a main body 201, an assembly portion 202 extending from the main body 201, and a first buckle 203 arranged on the assembly portion 202. The first buckle 203 includes a first abutting portion 2031 extending in the vertical direction, a first buckling portion 2032 extending from the first abutting portion 2031 in the horizontal direction, and a protrusion 2033 extending from the first buckling portion 2032. The main body 201 is detachably mounted on the mounting portion 102 of the host 1. See Figure 8 As shown, the main body 201 encloses a storage space 2010. Figure 4 and Fig. 9 As shown, the assembly portion 202 is provided with a first hole 2020 , a second hole 2021 and a receiving groove 2022 .

[0042] See also Figures 5 to 7 As shown, the stirring blade assembly 21 includes a limiter 210, a rotating shaft 211 and a hand piece 212 assembled on the limiter 210, and a stirring blade 213 assembled on the rotating shaft 211. The hand piece 212 includes a top wall 2120, a side wall 2121 and a connecting portion 2122 extending from the top wall 2120, and a second buckle 2123 extending from the side wall 2121. The top wall 2120 is provided with a through hole 21201. The through hole 21201 is used for the rotating shaft 211 to pass through. The connecting portion 2122 is fixed to the limiter 210 by a fixing member 215. The fixing member 215 can be a bolt or the like. In other embodiments, the limiter 210 can also be integrally provided with the hand piece 212 and cannot be disassembled, for example, fixed together by integral molding or welding.

[0043] When the hand piece 212 is assembled to the housing 20, the assembly portion 202 of the housing 20 is partially accommodated in the space surrounded by the hand piece 212, and the side wall 2121 of the hand piece 212 is located above the main body 201 of the housing 20, which is convenient for holding the hand piece 212. The side wall 2121 is provided with an anti-slip portion 21210, which effectively increases the friction between the side wall 2121 and the hand, making it convenient to rotate the hand piece 212.

[0044] The second buckle 2123 includes a second abutting portion 21230 extending in the vertical direction, a second buckling portion 21231 extending in the horizontal direction from the second abutting portion 21230, and a recessed portion 21232 provided on the second buckling portion 21231. When the handpiece 212 is assembled with the shell 20, the handpiece 212 or the shell 20 is rotated so that the second buckling portion 21231 moves below the first buckling portion 2032, thereby limiting the movement of the handpiece 212 in the vertical direction. The first abutting portion 2031 is used to abut against the second buckling portion 21231, and the second abutting portion 21230 is used to abut against the first buckling portion 2032 to prevent the handpiece 212 or the shell 20 from rotating excessively, causing the second buckling portion 21231 to be separated from the first buckling portion 2032. Alternatively, only the first abutting portion 2031 or the second abutting portion 21230 may be provided.

[0045] The hand piece 212 is assembled and limited together with the housing 20 so that the rotating shaft 211 is limited, preventing the rotating shaft 211 from moving due to improper external force, and effectively ensuring the stability of the connection between the rotating shaft 211 and the motor of the host 1.

[0046] In other embodiments, the first buckle 203 and the second buckle 2123 can release the fastening relationship between the two by pressing. For example, by pressing one end of the first buckle 203, the first fastening portion 2032 is tilted to disengage from the fastening with the second fastening portion 21231, so that the first buckle 203 and the second buckle 2123 are disengaged.

[0047] When the second buckle 21231 is buckled with the first buckle 2032, the protrusion 2033 of the first buckle 203 is received in the recess 21232 of the second buckle 2123, preventing the second buckle 21231 from being buckled with the first buckle 2032 due to improper external force on the handpiece 212 or the housing 20, thereby effectively ensuring the stability of the holding of the handpiece 212 and the housing 20. The protrusion 2033 can also be provided on the second buckle 2123, and correspondingly, the recess 21232 is provided on the first buckle 203.

[0048] Reference Figures 8 to 9As shown, the protective cover 22 includes a positioning portion 220 and a side wall 221 extending from the positioning portion 220. The side wall 221 is arranged to surround the outer periphery of the mixing blade 213 to prevent the mixing blade 213 from being exposed and causing potential danger; at the same time, the side wall 221 can also play a role of spoiler, so that the mixing effect of the mixing blade 213 is better.

[0049] When the stirring device 2 is assembled, the rotating shaft 211 passes through the space surrounded by the protective cover 22, one end of the rotating shaft 211 passes through the first hole 2020 of the shell 20 and is located in the storage space 2010 of the shell 20, and the other end is assembled with the stirring blade 213. When the stirring device 2 is assembled to the host 1, the rotating shaft 211 is connected to the motor of the host 1, so that the motor can drive the rotating shaft 211 to rotate, and further drive the stirring blade 213 to rotate to whip the food; the positioning portion 22 of the protective cover 22 0 passes through the through hole 21201 of the handpiece 212 and is received in the receiving groove 2022 of the shell 20 to fix the protective cover 22 to the shell 20; the connecting portion 2122 of the handpiece 212 passes through the second hole 2021 of the shell 20, and the limiting member 210 is located in the receiving space 2010 of the shell 20. The limiting member 210 is located below the assembly portion 202 of the shell 20 to prevent the stirring blade assembly 21 from detaching from the shell 20 when it moves up and down relative to the shell 20.

[0050] In other embodiments, the stopper 210 may be removed, the rotating shaft 211 may be fixed to the hand piece 212, and the hand piece 212 may be moved to drive the rotating shaft 211 to move. After the rotating shaft 211 moves, it may abut against the housing 20 to prevent the stirring blade assembly 21 from being separated from the housing 20. A reset spring may be provided between the rotating shaft 211 and the housing 20, and when the stirring blade 213 is cleaned, the reset spring may drive the stirring blade 213 to move into the space enclosed by the side wall 221 of the protective cover 22.

[0051] When the stirring device 2 of the embodiment of the present application is in use, when the stirring blade 213 needs to be cleaned, the handpiece 212 or the shell 20 is rotated so that the second buckle 2123 is disengaged from the buckle of the first buckle 203, and the handpiece 212 is pushed upward to drive the stirring blade assembly 21 to move upward so that the stirring blade 213 is moved out of the space in the protective cover 22 to facilitate the cleaning of the stirring blade; when cleaning the stirring blade 213, the handpiece 212 can be supported by hand so that the stirring blade 213 remains in a state of being moved out of the space in the protective cover 22, or the stirring blade 213 is placed downward. Due to the influence of gravity, the stirring blade 213 remains in a state of being moved out of the space in the protective cover 22, preventing the stirring blade 213 from retracting into the space in the protective cover 22, and the operation is more labor-saving.

[0052] When the stirring device 2 of the embodiment of the present application is used, after the stirring blade 213 is cleaned, the handpiece 212 is pulled downward to drive the stirring blade assembly 21 to move downward. When the side wall 2121 of the handpiece 212 moves to abut against the main body 201 of the shell 20, the handpiece 212 or the shell 20 is rotated so that the second buckling portion 21231 is buckled with the first buckling portion 2032 to limit the stirring blade assembly 21 to the shell 20. At the same time, the stirring blade 213 is located in the space surrounded by the side wall 221 of the protective cover 22. When the handpiece 212 of the embodiment of the present application moves, the stirring blade 213 is driven to move. In other embodiments, the stirring blade 213 can also be moved relative to the protective cover 22 by rotating the handpiece 212.

[0053] Reference Fig.10 As shown, in the second embodiment, after the stirring blade 213 is removed from the space enclosed by the side wall 221 of the protective cover 22, it can be disassembled from the rotating shaft 211, which makes it easier to clean the stirring blade 213. The stirring blade 213 is fixed to the rotating shaft 211 by threaded connection, so as to facilitate the disassembly and assembly of the stirring blade 213.

[0054] Reference Fig.11 As shown, in the third embodiment, the stirring blade 213 and the rotating shaft 211 are detachable. The stirring blade 213 includes a blade body 2130, a retaining member 2131 fixed to the blade body 2130, and an elastic member 2132 assembled to the retaining member 2131. The retaining member 2131 is provided with an assembly hole 21310. The rotating shaft 211 includes a base 2111 and a blocking portion 2110 extending from the base 2111. The diameter of the blocking portion 2110 is greater than the diameter of the base 2111. When the stirring blade 213 is assembled with the rotating shaft 211, the blocking portion 2110 is pressed into the assembly hole 21310, and the elastic member 2132 moves upward to pass over the blocking portion 2110. Due to the elastic force of the elastic member 2132, the blocking portion 2110 is limited in the assembly hole 21310. The blocking portion 2110 is spherical, which is convenient for assembling and disassembling the stirring blade 213. When the stirring blade 213 needs to be disassembled, the stirring blade 213 is pulled downward to separate the stirring blade 213 from the rotating shaft 211.

[0055] The stirring device 2 of the embodiment of the present application includes a handpiece 212 assembled on the rotating shaft 211, and the handpiece 212 is exposed from the housing 20. Pushing or rotating the handpiece 212 can drive the stirring blade 213 to move relative to the protective cover 22, so as to be removed from the space surrounded by the side walls 221 of the protective cover 22, so as to facilitate the cleaning of the stirring blade 213. Since the handpiece 212 is exposed from the housing 20, it is convenient to operate the handpiece 212; the handpiece 212 can be assembled and fixed with the housing 20 to ensure that the stirring blade 213 is located in the space surrounded by the side walls 221 of the protective cover 22, so as to prevent the rotating shaft 211 from being moved. The motor that is moved and separated from the main unit 1 due to improper external force ensures the stability of the mixer; the second buckle 2123 is located on the inner side of the side wall 2121, and the first buckle 203 and the second buckle 2123 are buckled by rotating the handpiece 212. Such a design can hide the first buckle 203 and the second buckle 2123, making the appearance of the stirring device 2 neat; at the same time, it can prevent the first buckle 203 and the second buckle 2123 from being separated due to improper external force, effectively ensuring the stability of the connection between the rotating shaft 211 of the stirring device 2 and the motor of the main unit 1.
