[0038] like Figure 1-Figure 5As shown, this embodiment provides a power connection structure, which includes a first connection member 1, a driver 2, a base 3, a second connection member 4 and an elastic member 5. The first connection member 1 is rotatably arranged on the main structure around a first direction, the driver 2 is arranged on the main structure, the base 3 is arranged at the output end of the driver 2, the driver 2 can drive the base 3 to rotate around the first direction, the second connection member 4 is slidably arranged in the base 3 along the first direction, the two ends of the elastic member 5 are respectively connected to the base 3 and the second connection member 4, and the second connection member 4 can be clamped to the first connection member 1 under the support of the elastic member 5.

[0039] In this embodiment, the first connecting member 1 is rotatably arranged on the main structure around the first direction, so that the first connecting member 1 can rotate relative to the main structure. The driver 2 is arranged on the main structure to ensure the connection stability between the driver 2 and the main structure. The base 3 is arranged at the output end of the driver 2, and the driver 2 can drive the base 3 to rotate around the first direction. The second connecting member 4 is slidably arranged in the base 3 along the first direction, and the second connecting member 4 can be driven to rotate around the first direction by the rotation of the base 3. The two ends of the elastic member 5 are respectively connected to the base 3 and the second connecting member 4. When the user installs the first connecting member 1 on one end of the second connecting member 4, the second connecting member 4 will abut against one end of the first connecting member 1 under the support of the elastic member 5. When the driver 2 drives the second connecting member 4 to rotate, the second connecting member 4 can be clamped on the first connecting member 1, thereby realizing the connection between the second connecting member 4 and the output end of the driver 2, ensuring that the power can be stably transmitted to the first connecting member 1 through the driver 2, through the base 3, the second connecting member 4 and the elastic member 5, without the need for the user to accurately align, and the operation is more convenient and quick. Through the above arrangement, the power connection structure of this embodiment can simplify the installation process of the driver 2 and the first connecting member 1, improve the installation efficiency, and facilitate and speed up the operation.

[0040] It is understandable that the driver 2 of this embodiment adopts a servo motor or a stepper motor and other structures, as long as it can achieve the above-mentioned functions, and no excessive restrictions are made here. The main structure of this embodiment (not shown in the figure) is not limited to pet snack machines, pet food machines, and pet water dispensers, etc., which require the motor to be centrally connected with related components, and no excessive elaboration is made here. In addition, in this embodiment, the first direction is a vertical direction to simplify the installation process of the driver 2 and the first connecting member 1 and improve the working efficiency. In other embodiments, the first direction can be adjusted according to the actual installation process, and no excessive restrictions are made here.

[0041] Specifically, Figure 1-Figure 5As shown, one of the first connector 1 and the second connector 4 is provided with a protruding portion, and the other is provided with a recessed portion, and the first connector 1 and the second connector 4 can be mutually engaged through the protruding portion and the recessed portion. In this embodiment, the first connector 1 is provided with a recessed portion, and the second connector 4 is provided with a protruding portion. When the user installs the first connector 1 on one end of the second connector 4, due to the supporting effect of the elastic member 5, the second connector 4 will abut against one end of the first connector 1. At this time, the protruding portion cooperates with the recessed portion, so that the first connector 1 and the second connector 4 can be mutually engaged. When the driver 2 drives the base 3 and the second connector 4 to rotate, this engaging structure ensures that the power can be stably transmitted from the driver 2 to the first connector 1. Not only the efficiency of installation and disassembly is improved, but also the stability and applicability of the connection are enhanced. In other embodiments, a protruding portion may also be provided on the first connector 1, and a recessed portion may be provided on the second connector 4. It is only necessary to ensure that each recessed portion is provided with a protruding portion that can be engaged with it, and no limitation is made here.

[0042] More specifically, if Figure 3 and Figure 5 As shown, the protruding portion includes a plurality of protrusions 41, which are arranged at intervals along the circumference of the second connecting member 4, and the recessed portion includes a plurality of grooves 11, which are arranged at intervals along the circumference of the first connecting member 1. When the second connecting member 4 abuts against the first connecting member 1 under the support of the elastic member 5, the plurality of protrusions 41 can be snapped into the plurality of grooves 11 one by one, thereby further improving the connection stability between the first connecting member 1 and the second connecting member 4. At the same time, the one-to-one snap connection between the plurality of protrusions 41 and the plurality of grooves 11 ensures that the first connecting member 1 and the second connecting member 4 can be accurately aligned when connected. This not only simplifies the installation process, but also improves the accuracy of the installation, and avoids connection problems caused by misalignment.

[0043] More specifically, chamfers are provided at both ends of the protrusion 41, which can reduce friction and guide the protrusion 41 to enter the groove 11 more easily, thereby reducing the difficulty of operation and improving the assembly efficiency of the first connecting member 1 and the second connecting member 4. At the same time, by setting the chamfers, the contact between the first connecting member 1 and the second connecting member 4 is made more uniform, and stress concentration is reduced. When the first connecting member 1 cannot continue to rotate relative to the main structure due to resistance, the chamfered inclined surface or arc structure allows the protrusion 41 to slide outward along the inclined surface more easily, so that the connection between the first connecting member 1 and the second connecting member 4 becomes loose, so that the first connecting member 1 and the second connecting member 4 can be automatically separated and disengaged, thereby avoiding damage or failure of the driver 2 due to excessive resistance.

[0044] Specifically, Figure 3 and Figure 4As shown, the base 3 is provided with a guide column 31 extending in the first direction, and the elastic member 5 is sleeved on the guide column 31, one end of which is connected to the base 3, and the other end is connected to the second connecting member 4, so as to ensure that the elastic member 5 can be deformed along the extension direction of the guide column 31 during the deformation process, and avoid the elastic member 5 from shaking and shifting. When the second connecting member 4 slides in the base 3 under the action of external force, the elastic member 5 can be elastically deformed to provide necessary support and buffering for the second connecting member 4. At the same time, when the external force disappears, the elastic member 5 can restore its original shape and push the second connecting member 4 to reset.

[0045] More specifically, if Figure 3 and Figure 4 As shown, a through slot 311 extending in a first direction is provided in the guide column 31, and the base 3 is sleeved on the output end of the driver 2 through the through slot 311. It can be understood that the driver 2 of this embodiment adopts a motor, that is, the output shaft of the motor can be passed through and connected to the through slot 311, so as to improve the connection stability between the base 3 and the driver 2, which not only simplifies the installation process, but also improves the stability and reliability of the connection.

[0046] Specifically, Figure 1-Figure 4 As shown, the base 3 includes a bottom plate 32 and a side tube 33. The bottom plate 32 is connected to the output end of the driver 2 to ensure the stability of the base 3 as a whole during operation. One end of the side tube 33 is connected to the bottom plate 32 and is surrounded to form a slide groove 331. The second connecting member 4 is slidably connected to the slide groove 331 to ensure the stability and accuracy of the second connecting member 4 during the sliding process, so as to ensure that the second connecting member 4 can move appropriately in the slide groove 331 under the support of the elastic member 5 and abut against the first connecting member 1, which provides convenience for the connection between the second connecting member 4 and the first connecting member 1.

[0047] More specifically, if Figure 3 As shown, a guiding protrusion is provided on the inner wall of the side tube 33, and a guiding recess matching the guiding protrusion is provided on the second connecting member 4, so that the second connecting member 4 can only be slidably connected in the slide groove 331 along the first direction, and cannot rotate relative to the slide groove 331, so as to ensure that the second connecting member 4 and the base 3 can rotate synchronously around the first direction to avoid affecting the connection between the first connecting member 1 and the second connecting member 4.

[0048] More specifically, Figure 1-Figure 4 As shown, the other end of the side tube 33 is provided with an opening, and an annular flange 332 is provided along the circumference of the opening. The protrusion 41 on the second connecting member 4 can extend out from the opening, and the second connecting member 4 can abut against the annular flange 332 through the protrusion 41, which can ensure the stability and accuracy of the above-mentioned components during the connection process and prevent the second connecting member 4 from slipping out of the slide groove 331.

[0049] Specifically, Figure 4 As shown, the second connecting member 4 is provided with a limiting groove 42, and one end of the elastic member 5 abuts against the limiting groove 42 to ensure that the elastic member 5 can be stably fixed on the second connecting member 4. Through the above arrangement, one end of the elastic member 5 is effectively fixed and will not move or fall off at will.

[0050] Specifically, Figure 3 and Figure 4 As shown, the diameter of the elastic member 5 gradually decreases in the direction away from the second connecting member 4, forming a conical structure, so that the elastic member 5 can distribute stress more evenly when subjected to force, reducing stress concentration, thereby improving the durability and reliability of the elastic member 5.

[0051] Specifically, Figure 1-Figure 4 As shown, the first connecting member 1, the second connecting member 4, the elastic member 5, the base 3 and the driver 2 are arranged in sequence from top to bottom, and the first connecting member 1 is located at the top to facilitate the user to perform installation, disassembly and maintenance operations more conveniently; the second connecting member 4 is located below the first connecting member 1 and is connected to the first connecting member 1 through the elastic member 5, so that the second connecting member 4 can be flexibly connected or separated from the first connecting member 1 when driven by the driver 2, so as to achieve stable transmission of power; the elastic member 5 is located between the second connecting member 4 and the base 3, and plays a supporting and buffering role; the base 3, as a key component connecting the driver 2 and the second connecting member 4, is located below the elastic member 5, and is connected to the output end of the driver 2 through the through groove 311, so as to ensure that the power output by the driver 2 can be stably transmitted to the second connecting member 4; the driver 2 is located at the bottom of the entire structure, providing a power source for the entire structure. Through the above arrangement, the entire structure is more compact and orderly, and is also conducive to the stability and efficiency of power transmission.

[0052] It should be noted that the elastic member 5 of this embodiment is a rotation spring, a compression spring, etc. In the pet snack machine, the first connecting member 1 is an upper cover for stirring and dispersing pet food, and the second connecting member 4 is a barrel-shaped structure. As long as the above functions can be achieved, the specific structures of the first connecting member 1 and the second connecting member 4 are not limited too much.

[0053] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
