[0060] like Figures 1 to 6 As shown, in some embodiments of the present invention, the device body 100 is configured in the form of a clip.

[0061] However, those skilled in the art should understand that, in the present invention, the device body 100 can also be in any other feasible form, such as a clip form, a hook form, a plate form, a strip form, a suction cup form, etc.

[0062] Refer to the following Figures 1 to 6 The device body 100 in some embodiments of the present invention will be described in detail so that those skilled in the art can better understand the technical solutions of the present invention.

[0063] like Figures 1 to 6 As shown, in some embodiments of the present invention, the device body 100 includes a first fixing mechanism 110, a second fixing mechanism 120 and a rotating shaft 130. The first fixing mechanism 110 and the second fixing mechanism 120 are rotatably connected through the rotating shaft 130 so that the device body 100 is fixed to the target food 002 by clamping.

[0064] like Figures 1 to 6 As shown, in some embodiments of the present invention, the first fixing mechanism 110 includes a clamping member 111 rotatably connected to the second fixing mechanism 120 and a movable member 112 rotatably connected to the clamping member 111 .

[0065] like Figures 1 to 8 As shown, in some embodiments of the present invention, the clamping member 111 is rotatably connected to the root of the movable member 112 through its root, so as to improve the structural utilization of the clamping member 111 and the movable member 112.

[0066] Continue reading Figures 1 to 8 In some embodiments of the present invention, the clamping member 111 is provided with a protrusion 1111 at its root, and the movable member 112 is provided with an avoidance cavity 1121 at its root for avoiding the protrusion 1111. The movable member 112 in the folded state makes the side wall of the avoidance cavity 1121 abut against the protrusion 1111 (e.g. Figure 4 shown).

[0067] Those skilled in the art will understand that by providing the clamping member 111 with a protrusion 1111 at its root, and providing the movable member 112 with an avoidance cavity 1121 at its root for avoiding the protrusion 1111, the movable member 112 in a folded state can abut against the protrusion 1111 through the side wall of the avoidance cavity 1121, thereby ensuring both the driving effect of the movable member 112 on the clamping member 111 and the folding effect of the movable member 112 and the clamping member 111.

[0068] from Figures 1 to 4As can be seen in the figure, in some embodiments of the present invention, the protrusion 1111 and the head of the clamping member 111 are respectively located on either side of the rotating shaft 130. In this way, the point of force applied by the movable member 112 against the clamping member 111 can be located on the side of the opening direction of the clamping member 111, thereby allowing the user to drive the movable member 112 to rotate the clamping member 111 with only a small force.

[0069] from Figures 1 to 4 It can also be seen that in some embodiments of the present invention, the avoidance cavity 1121 and the head of the movable member 112 are located on the same side of the rotating shaft 130 so that Figure 4 The movable member 112 in the folded state shown in FIG can be attached to the clamping member 111 .

[0070] from Figures 1 to 4 It can also be seen that in some embodiments of the present invention, the clamping member 111 is rotatably connected to the middle part of the second fixing mechanism 120 through its root, so that a part of the second fixing mechanism 120 corresponds to the clamping member 111 and jointly clamps the target food 002; and another part of the second fixing mechanism 120 corresponds to the movable member 112 for the user to press, thereby opening the clamping member 111.

[0071] like Figure 5 and Figure 6 As shown, in some embodiments of the present invention, a connecting arm 121 is provided in the middle of the second fixing mechanism 120, so that the second fixing mechanism 120 is rotatably connected to the clamping member 111 through the connecting arm 121. A through hole is provided on the connecting arm 121 to allow the rotating shaft 130 to pass through.

[0072] like Figures 1 to 6 As shown, in some embodiments of the present invention, the clamping member 111 , the movable member 112 and the second fixing mechanism 120 are all rotatably connected together via the rotating shaft 130 .

[0073] The rotating shaft 130 may be a solid rod-shaped structure or a hollow rod-shaped structure.

[0074] Those skilled in the art will appreciate that by rotatably connecting the clamping member 111 , the movable member 112 and the second fixing mechanism 120 together via the rotating shaft 130 , the structure of the device body 100 is effectively simplified and the production cost of the device body 100 is reduced.

[0075] Of course, in other embodiments of the present invention, those skilled in the art may also, as needed, rotatably connect the clamping member 111 and the movable member 112 together through a rotating shaft 130 , and rotatably connect the clamping member 111 and the second fixing mechanism 120 together through another rotating shaft 130 .

[0076] from Figure 5 and Figure 6 As can be seen in some embodiments of the present invention, mounting holes (not marked in the figure) are respectively provided on the clamping member 111 and the movable member 112 to mount the rotating shaft 130 .

[0077] like Figure 2 、 Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the device body 100 further includes an elastic member 140 , which is used to provide a force for clamping the target food 002 to the first fixing mechanism 110 and the second fixing mechanism 120 .

[0078] from Figure 5 and Figure 6 It can be seen from the figure that in some embodiments of the present invention, the elastic member 140 is a torsion spring, and one end of the torsion spring abuts against the clamping member 111 , and the other end abuts against the second fixing mechanism 120 .

[0079] Specifically, the clamping member 111 is provided with a first positioning groove 1112 at the protruding portion 1111 to position and clamp one end of the torsion spring. The second fixing mechanism 120 is provided with a second positioning groove 1201 to position and clamp the other end of the torsion spring.

[0080] from Figure 5 and Figure 6 As can be seen in the figure, the torsion spring is provided with a bend at each end to increase the contact area between the torsion spring and the clamping member 111 and the second fixing mechanism 120. Of course, those skilled in the art can also configure the two ends of the torsion spring to be straight rods or columns without bends as needed to facilitate the fixation of the torsion spring to the clamping member 111 and the second fixing mechanism 120.

[0081] In addition, on the premise that the first fixing mechanism 110 and the second fixing mechanism 120 can clamp the target food 002, those skilled in the art may also, as needed, set the elastic member 140 to any other feasible structure, such as a compression spring, a tension spring, a V-shaped spring sheet, an elastic sheet integrally made with the first fixing mechanism 110 or the second fixing mechanism 120, etc.

[0082] like Figures 7 to 10As shown, in some embodiments of the present invention, the mounting structure 200 includes a slot 210 arranged on the device body 100, and the slot 210 has a notch 211 formed on the outer surface of the device body 100, so that the electronic tag 300 can be inserted into the slot 210 from the outside of the intelligent food management device 001 through the notch 211.

Therefore, the smart food management device 001 of the present invention allows the user to replace the electronic tag 300 without disassembling the device body 100, making the operation more convenient.

[0084] like Figures 7 to 9 and Figure 11 As shown, in some embodiments of the present invention, the mounting structure 200 may further include a tray 220 adapted to fit the slot 210, and the tray 220 may be removably plugged into the slot 210. The tray 220 is used to carry the electronic tag 300, so that the electronic tag 300 can be inserted into or removed from the slot 210 along with the tray 220, thereby achieving installation and removal of the electronic tag 300.

[0085] Those skilled in the art will appreciate that by having the mounting structure 200 further include a tray 220 adapted to the slot 210, having the tray 220 removably plugged into the slot 210, and having the tray 220 carry the electronic tag 300, the electronic tag 300 can be inserted into or removed from the slot 210 along with the tray 220. This allows the user to install and remove the electronic tag 300 simply by manipulating the tray 220, making the operation more convenient. Furthermore, the tray 220 can protect the electronic tag 300 by preventing it from bending.

[0086] like Figure 7 and Figure 8 As shown, in some embodiments of the present invention, a limiting structure 2201 is provided on the tray 220. The limiting structure 2201 is used to limit the position of the electronic tag 300 placed on the tray 220 to prevent the electronic tag 300 from falling off the tray 220, thereby ensuring the stability of the installation and removal of the electronic tag 300.

[0087] from Figure 7 and Figure 8As can be seen in the figure, the limiting structure 2201 is a recessed groove provided on the disc body 221, so that the electronic tag 300 is embedded in the recessed groove, so that the disc body 221 wraps the electronic tag 300 in the circumferential direction.

[0088] Furthermore, the bottom wall of the trough can be as follows Figure 7 and Figure 8 As shown, a through hole is provided, and the size of the through hole is smaller than the size of the sink, so as to ensure that the sink can support the electronic tag 300 through its bottom wall.

[0089] Those skilled in the art will appreciate that the through hole can facilitate cleaning of the sink.

[0090] like Figure 7 and Figure 8 As shown, in some embodiments of the present invention, the tray 220 includes a tray body 221 and an end cover 222 located at the outer end of the tray body 221. The slot 210 includes an inner slot portion 212 adapted to the tray body 221 and an outer slot portion 213 adapted to the end cover 222, so that the end cover 222 is embedded in the outer slot portion 213 (as shown in FIG.
