[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] As Figures 1-7 shown, the present invention provides an anti-misoperation exit safety device for a blender, including a body 1 with a driving device built therein, a first mounting part 103 and a second mounting part 104 provided on the body 1. The first mounting part 103 is provided with a juicer 101, the second mounting part 104 is provided with a meat grinder 102, the second mounting part 104 is further provided with an anti-misoperation exit mechanism 2, and the meat grinder 102 is connected to the driving device built in the body 1 through the anti-misoperation exit mechanism 2. The meat grinder 102 is provided with a locking end 105 corresponding to the position of the anti-misoperation exit mechanism 2.

[0030] In one of the embodiments, the first mounting part 103 and the second mounting part 104 provided on the body 1 are respectively used for installing a fruit juicer 101 and a meat grinder 102. The second mounting part 104 is provided with an anti-misoperation exit safety device, which combines two locking methods and can greatly improve the reliability of the structure after being used in cooperation with the locking end 105 on the meat grinder 102.

[0031] The anti-misoperation exit mechanism 2 includes a protection structure 201, a locking structure and an exit structure 214. The locking structure successively includes a connecting shaft 205, a bush 206, a fixed seat 207 and a locking seat 209. The exit structure 214 successively includes a guide sleeve 208, a movable shaft 210, a top column 213, a connecting seat 216 and an elastic member. The connecting shaft 205 and the bush 206 are coaxially arranged, and both the connecting shaft 205 and the bush 206 are provided with mutually engaged convex portions.

[0032] In the second embodiment, during the installation of the meat grinder 102, the front cover 202 of the protective structure 201 needs to be disassembled downstairs. The rear cover 204 is fixed to the body 1 by screws. The locking end 105 of the meat grinder 102 can be sealed by a seal 203, further enhancing the sealing effect. The locking end 105 of the meat grinder 102 is clamped according to the protrusion on the locking seat 209 until it is clamped with the corresponding ejector pin 213 to complete the installation.

[0033] The fixing seat 207 is mounted on the bushing 206, the bushing 206 is passed through the locking seat 209, and a plurality of buckles 212 are provided on the locking seat 209, and the buckles 212 are connected to the locking end 105.

[0034] The movable shaft 210 is passed through the guide sleeve 208. The guide sleeve 208 passes through the locking seat 209 and is connected to the connecting seat 216. An elastic member is connected between the connecting seat 216 and the locking seat 209, and the connecting seat 216 is connected to the ejector pin 213.

[0035] In the third embodiment, when the first locking ring 106 and the second locking ring 107 of the locking end 105 are sequentially clamped on the buckle 212, the meat grinder 102 is rotated counterclockwise to make the slots of the first locking ring 106 and the second locking ring 107 correspond to the buckle 212 for clamping. The locked rings that have completed the clamping are also clamped with the ejector pin 213 through another slot. Since the ejector pin 213 is connected to the movable shaft 210 through an elastic member, when the movable shaft 210 is pressed down along the axis, the ejector pin 213 moves synchronously in the same way. The ejector pin 213 has elasticity through the elastic member, so that the ejector pin 213 is clamped in the corresponding slot, thereby preventing the meat grinder 102 from loosening or falling. Similarly, when the meat grinder 102 needs to be removed, the movable shaft 210 needs to be pressed down so that the ejector pin 213 is separated from the slot of the locking ring, and then the meat grinder 102 can be rotated clockwise and removed.

[0036] Furthermore, the second installation part 104 is also provided with a drive shaft 211 for connecting the built-in drive device of the body 1. The drive shaft 211 is connected to the connecting shaft 205. The connecting shaft 205 and the protrusion on the bushing 206 are serrated, and the connecting shaft 205 and the bushing 206 are meshed and connected to each other. The connecting shaft 205 rotates in the axial direction of the bushing 206 through the drive shaft 211.

[0037] Furthermore, the locking end 105 is in contact with the ejector pin 213. The locking end 105 includes a first locking ring 106 and a second locking ring 107. The first locking ring 106 and the second locking ring 107 are coaxially arranged, and both the first locking ring 106 and the second locking ring 107 are provided with first slots for clamping the buckle 212 of the locking seat 209.

[0038] Further, the protection structure 201 includes a front cover 202, a seal 203 and a rear cover 204. The front cover 202 is detachably connected to the rear cover 204. The rear cover 204 is fixedly connected to the body 1. An installation opening for installing the meat grinder 102 is formed in the middle of the rear cover 204.

[0039] Further, a first through hole for installing the guide sleeve 208 is provided on both the fixed seat 207 and the locking seat 209. The guide sleeve 208 sequentially penetrates through the fixed seat 207 and the locking seat 209 along the axial direction of the bushing 206. The movable shaft 210 moves along the axial direction of the bushing 206. The connecting seat 216 enables the ejector pin 213 to move along the axial direction of the locking seat 209 through the movable shaft 210. A second through hole for installing the ejector pin 213 is further provided on the locking seat 209.

[0040] Further, the elastic member is a return spring 215. The two ends of the return spring 215 are respectively connected to the locking seat 209 and the connecting seat 216, and the return spring 215 is arranged along the axial direction of the locking seat 209.

[0041] Further, a second card slot is further provided on the first lock ring 106 and the second lock ring 107. The ejector pin 213 is inserted into the second card slot, and there is a movable gap between the ejector pin 213 and the second card slot.

[0042] In summary, during use, after the locking end 105 of the corresponding stirrer or meat grinder 102 is installed on the installation part on the stirring body 1, it is rotated in a specified direction to lock the two. Among them, the locking structure of the anti-misoperation withdrawal mechanism 2 can lock the stirrer or the meat grinder 102. This structure needs to be disassembled by rotating in a specified direction after the body 1 and the stirrer are separated by the withdrawal structure 214 in the anti-misoperation withdrawal mechanism 2. This structure greatly improves the safety of the structure, thus avoiding the harm to the user when the stirrer falls during the operation of the mixer, and also avoiding the waste of food due to the falling of the stirrer food, and further improving the structural reliability.

[0043] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
