[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] Please refer to Figures 1 to 4As shown, in an embodiment of the utility model, a pet feeder is provided, comprising a main body 1, a grain bowl assembly 2, a weighing unit 3 and a limiting member 4. The grain bowl assembly 2 is used to contain grains, and the bottom of the grain bowl assembly 2 has a grain bowl slot 21. The weighing unit 3 is disposed in the grain bowl assembly 2, and is used to weigh the grain in the grain bowl assembly 2. The limiting member 4 is at least partially connected to the main body 1, and the limiting member 4 has a first plug-in portion 41, and the first plug-in portion 41 is used to plug and cooperate with the grain bowl slot 21 to limit the grain bowl assembly 2, and the upper wall of the first plug-in portion 41 and the inner wall of the grain bowl slot 21 are spaced apart in the vertical direction.

[0036] Specifically, the main body 1 refers to the main component of the pet feeder, and the function of the main body 1 is to store food and deliver the food when feeding is needed. The food bowl assembly 2 refers to a container assembly for holding food, and the food bowl assembly 2 usually has an upward opening to facilitate the placement of food and the feeding of the pet. The weighing unit 3 refers to a measuring device that can weigh an object. The weighing unit 3 can be a weighing sensor that converts the weight of an object into an electrical signal, or it can be other equipment that measures the weight of an object. By setting the weighing unit 3 on the food bowl assembly 2, the pet food can be weighed when the food bowl assembly 2 contains pet food. The weighing unit 3 can also cooperate with the control unit in the main body 1 to stop putting pet food into the food bowl assembly 2 after the pet food in the food bowl assembly 2 reaches a specified weight, making the entire pet feeder more intelligent to use.

[0037] The grain bowl slot 21 refers to a groove structure with a certain accommodation space. In normal use, the grain bowl assembly 2 is generally placed on a horizontal surface such as the ground or a desktop, and the opening of the grain bowl slot 21 is generally arranged downward.

[0038] The limiting member 4 refers to a component with a certain volume, and its function is to connect the grain bowl assembly 2 with the main body 1. The first plug-in portion 41 refers to at least a part of the limiting member 4, and the shape of the first plug-in portion 41 can be block-shaped, column-shaped, or strip-shaped. The plug-in cooperation of the first plug-in portion 41 and the grain bowl slot 21 means that the first plug-in portion 41 can be inserted from the bottom to the inside of the grain bowl slot 21 through the opening of the grain bowl slot 21, and the connection between the grain bowl assembly 2 and the limiting member 4 can be achieved through the cooperation of the two, and the grain bowl assembly 2 can be limited when the grain bowl assembly 2 is in normal use. In addition, the first plug-in portion 41 and the inner wall of the grain bowl slot 21 can be a detachable connection, which can facilitate the connection and disassembly between the grain bowl assembly 2 and the limiting member 4.

[0039] The upper wall of the first plug-in portion 41 and the inner wall of the grain bowl slot 21 are spaced apart in the vertical direction. At the same time, the surface of the first plug-in portion 41 except the upper wall and the inner wall of the grain bowl slot 21 in other directions (for example, in the horizontal direction) may be in contact with each other or spaced apart from each other. This can be selected according to actual conditions and will not be elaborated here.

[0040] The pet feeder provided by the embodiment of the utility model has a weighing unit 3 arranged on the grain bowl assembly 2, and the grain in the grain bowl assembly 2 is weighed by the weighing unit 3. A grain bowl slot 21 is also arranged at the bottom of the grain bowl assembly 2, and at least part of the limiting member 4 is connected to the main body 1, and the limiting member 4 also has a first plug-in portion 41 protrudingly arranged. When the grain bowl assembly 2 is in use, the first plug-in portion 41 can be inserted from the bottom to the grain bowl slot 21, and the grain bowl assembly 2 and the main body 1 are connected and fixed by the plug-in cooperation of the first plug-in portion 41 and the grain bowl slot 21. Compared with the pet feeder in the prior art, the upper wall of the first plug-in portion 41 and the inner wall of the grain bowl slot 21 are arranged at intervals in the vertical direction, so as to avoid the first plug-in portion 41 supporting the grain bowl assembly 2 in the vertical direction, thereby avoiding the grain bowl assembly 2 from being subjected to self-force dispersion due to being supported, which affects the measurement result of the weighing unit 3, and making the weighing measurement more accurate.

[0041] In an alternative embodiment, see Figure 2 and Figure 3 , the outer wall of the first plug-in portion 41 includes a plurality of first surfaces 44 and a second surface 45 connecting the plurality of first surfaces 44, wherein the upper wall of the first plug-in portion 41 may refer to the first surface 44. When the pet feeder is placed on a table or the ground for normal use, the first surfaces 44 on the first plug-in portion 41 may all be in the horizontal direction, and the second surface 45 may be in the vertical direction. When the first plug-in portion 41 is inserted into the grain bowl slot 21, the first surfaces 44 are spaced apart from the inner wall of the grain bowl slot 21 in the vertical direction, the second surface 45 may contact the inner wall of the grain bowl slot 21, and the second surface 45 may also be spaced apart from the inner wall of the grain bowl slot 21, thereby preventing the first plug-in portion 41 from supporting the grain bowl assembly 2.

[0042] In one embodiment, see Figure 3An electrical connection component 5 is provided between the grain bowl component 2 and the limiting member 4. The electrical connection component 5 is used to electrically connect the electrical components on the grain bowl component 2 with the electrical components on the main body 1 when the first plug-in portion 41 is plugged into the grain bowl slot 21. Specifically, the electrical connection component 5 refers to a component that can connect two circuits. The electrical components on the grain bowl component 2 may include but are not limited to the weighing unit 3=; the electrical components on the main body 1 may include but are not limited to the power supply unit, the processor and other parts. The setting of the electrical connection component 5 can be used to electrically connect the electrical components on the grain bowl component 2 with the electrical components on the main body 1 through the electrical connection component 5 when the first plug-in portion 41 is plugged into the grain bowl slot 21, for example, the weighing unit 3 inside the grain bowl component 2 is electrically connected to the power supply unit in the main body 1; the weighing unit 3 can also be connected to the processor in the main body 1 through the setting of the electrical connection component 5, and the weight data detected by the weighing unit 3 can be transmitted to the processor, which is convenient for the processor to control and adjust the amount of food put in, making the use of the entire pet feeder more convenient.

[0043] In addition, when the first plug-in portion 41 and the grain bowl slot 21 are plugged into each other, the electrical connection component 5 can also play a role of mechanical connection, which can make the connection between the grain bowl component 2 and the limit member 4 more stable, and can avoid the shaking of the grain bowl component 2 relative to the limit member 4 to a certain extent, thereby improving the measurement accuracy of the weighing unit 3.

[0044] In one embodiment, see Figure 5 The electrical connection component 5 includes a first conductive member 51 and a second conductive member 52. The first conductive member 51 is arranged in the grain bowl component 2, and at least a part of the first conductive member 51 is located in the grain bowl slot 21. The second conductive member 52 is arranged on the limiting member 4. When the first plug-in portion 41 is plugged into the grain bowl slot 21, the second conductive member 52 abuts against the outside of the first conductive member 51. Specifically, the first conductive member 51 refers to a conductive component with a certain length. The cross-section of the first conductive member 51 can be circular, rectangular or other shapes. The cross-section refers to the cross-section taken by a plane perpendicular to the length direction of the first conductive member 51. The first conductive member 51 can be made of metal or other conductive materials. The second conductive member 52 is also a conductive member with a certain volume. The second conductive member 52 can be made of metal or other conductive materials. At least a part of the first conductive member 51 is located in the grain bowl slot 21, and the second conductive member 52 is arranged on the limiting member 4. When the first plug-in portion 41 is plugged into the grain bowl slot 21, the second conductive member 52 abuts against the portion of the first conductive member 51 located in the grain bowl slot 21 to achieve electrical connection between the two. While the grain bowl assembly 2 is connected and fixed to the limiting member 4, the electrical components on the grain bowl assembly 2 can also be electrically connected to the electrical components on the main body 1.

[0045] The second conductive member 52 can be directly arranged outside the stopper 4. When the first plug-in portion 41 is plugged into the grain bowl slot 21, the portion of the first conductive member 51 located in the grain bowl slot 21 can directly contact the second conductive member 52. Figure 6 As shown, the second conductive member 52 can also be arranged inside the stopper 4, and a plurality of avoidance holes are also arranged on the stopper 4, and the shape of the avoidance holes matches the cross-sectional shape of the first conductive member 51. When the first plug-in portion 41 is plugged into the grain bowl slot 21, the first conductive member 51 can be inserted into the avoidance hole through the avoidance hole and then contact the second conductive member 52, so that the first conductive member 51 and the second conductive member 52 can be electrically contacted, and the second conductive member 52 can also be protected.

[0046] In an alternative embodiment, see Figure 4 A PCB (Printed Circuit Board) can be provided inside the grain bowl assembly 2, and the other end of the first conductive member 51 is connected to the PCB, and then the PCB is fixed inside the grain bowl assembly 2. The connection and fixation between the first conductive member 51 and the grain bowl assembly 2 is achieved through the PCB, which can make the installation and fixation of the first conductive member 51 more convenient and firm. In addition, the electrical components inside the grain bowl assembly 2 can be electrically connected to the PCB through wires, making the arrangement of the internal circuit of the grain bowl assembly 2 more reasonable.

[0047] In addition, the number of conductive pins can be multiple, and the number of second conductive parts 52 matches the number of conductive pins. Multiple second conductive parts 52 can be installed on the same fixed plate, and then the fixed plate is installed on the limit member 4, which can make the installation of multiple second conductive parts 52 more convenient and more secure.

[0048] like Figure 3 As shown, the first conductive member 51 can be a conductive plug, a conductive pin or a PIN pin, one end of the first conductive member 51 is connected to the PCB board, and the other end of the first conductive member 51 can extend into the grain bowl slot 21. In addition, the first conductive member 51 is arranged along the plugging direction of the first plug-in portion 41, which can make the first conductive member 51 more convenient to use.

[0049] In one embodiment, see Figure 5The second conductive member 52 has two independent elastic abutment ends 521, which are arranged opposite to each other, and are used to cooperate with each other to clamp the first conductive member 51. Specifically, the elastic abutment end 521 refers to a component with a certain elasticity, and the elastic abutment end 521 can be in the shape of a block, a sheet, or a strip. By arranging the two elastic abutment ends 521 opposite to each other, when the first plug-in portion 41 and the grain basin slot 21 are plugged into each other, the first conductive member 51 can be inserted between the two elastic abutment ends 521. The two elastic abutment ends 521 clamp the first conductive member 51 under the action of their own elasticity, so that the contact between the first conductive member 51 and the second conductive member 52 can be closer. In addition, the connection between the first conductive member 51 and the second conductive member 52 can be made more secure through the clamping action of the two elastic abutting ends 521. Since the first conductive member 51 is connected to the grain bowl assembly 2 and the second conductive member 52 is connected to the limiting member 4, when the first conductive member 51 and the second conductive member 52 are firmly connected, the connection between the grain bowl assembly 2 and the limiting member 4 can also be made more secure and reliable, which can prevent the grain bowl assembly 2 from shaking relative to the limiting member 4 to a certain extent, thereby improving the accuracy of weighing measurement.

[0050] The second conductive member 52 can be integrally formed by stamping, and a metal plate can be formed into the second conductive member 52 by stamping and bending, so that the overall structure of the second conductive member 52 is more solid and reliable.

[0051] In an alternative embodiment, see Figure 5 A recessed portion matching the shape of the first conductive member 51 is provided on the elastic abutting end 521. The recessed portion can increase the contact area between the elastic abutting end 521 and the first conductive member 51, thereby improving the conductive performance between the first conductive member 51 and the elastic abutting end 521.

[0052] In one embodiment, see Figure 5, a contraction portion 511 is provided on the first conductive member 51, and the diameter of the contraction portion 511 is smaller than the diameter of the first conductive member 51 at other positions. Specifically, the contraction portion 511 refers to a section of the first conductive member 51 provided along the length of the first conductive member 51, and the diameter of the contraction portion 511 is smaller than the diameter of the first conductive member 51 at other positions. By providing the contraction portion 511, a circle of concave area (small waist structure) can be formed on the surface of the first conductive member 51. When the first conductive member 51 is inserted between the two elastic abutment ends 521, the two elastic abutment ends 521 can abut against the contraction portion 511, and the position can be limited along the length direction of the first conductive member 51, thereby further improving the firmness of the direct connection between the elastic abutment end 521 and the first conductive member 51, and making the first conductive member 51 more firmly and reliably plugged and fixed. In addition, when the first conductive member 51 is inserted between the two elastic abutting ends 521, when the two elastic abutting ends 521 abut against the contraction portion 511, there will be a sudden change in the friction force between the elastic abutting ends 521 and the first conductive member 51, thereby increasing the sense of fit of the first conductive member 51 when inserted between the two elastic abutting ends 521, making the first conductive member 51 more convenient to use.

[0053] Among them, transition fillets are provided at both ends of the contraction portion 511, so that when the first conductive member 51 is inserted between the two elastic abutment ends 521, the elastic abutment end 521 can slide into the contraction portion 511 more smoothly; at the same time, when the first conductive member 51 is pulled out from between the two elastic abutment ends 521, the elastic abutment end 521 can slide out of the contraction portion 511 more conveniently.

[0054] In an alternative embodiment, see Figure 5 A guide fillet is provided at the end of the first conductive member 51 close to the limiting member 4 , so that the first conductive member 51 can be inserted between the two elastic abutting ends 521 more conveniently.

[0055] In an alternative embodiment, see Figure 2 and Figure 3 The stopper 4 and the main body 1 can be an integral structure, or they can be a separate structure. When the stopper 4 and the main body 1 can be a separate structure, the stopper 4 also has a second plug-in portion 42, and a main body slot 14 is provided at the bottom of the main body 1. When the stopper 4 is connected to the main body 1, the second plug-in portion 42 can be inserted into the main body slot 14. Through the plug-in cooperation between the second plug-in portion 42 and the main body slot 14, the stopper 4 and the main body 1 are connected. In addition, after the second plug-in portion 42 is inserted into the main body slot 14, the second plug-in portion 42 can be fixed in the main body slot 14 at the bottom of the main body 1 by a fastener, which further increases the connection strength between the stopper 4 and the main body 1.

[0056] Among them, when the stopper 4 and the main body 1 are separate structures, a connection hole for the wire to pass through can also be provided on the stopper 4, and a connection hole for the wire to pass through can also be provided on the main body 1. After the second plug-in portion 42 is inserted into the main body slot 14, the second conductive member 52 provided on the stopper 4 can be electrically connected to the electrical components on the main body 1 by passing the wire through the two connection holes in sequence. Alternatively, an electrical connector can also be provided between the stopper 4 and the main body 1. The electrical connector generally includes two parts, one part is installed on the stopper 4, and the other part is installed on the main body 1. When the second plug-in portion 42 in the stopper 4 is plugged into the main body slot 14 on the main body 1, the two parts of the electrical connector are in contact with each other, so that the electrical connection between the stopper 4 and the main body 1 can also be achieved.

[0057] In one embodiment, see Figure 4 and Figure 6 , a positioning member 27 is arranged on the inner wall of the grain bowl slot 21, and the positioning members 27 are arranged along the insertion direction of the first plug-in portion 41, and a positioning hole 43 is arranged on the first plug-in portion 41, and the positioning hole 43 is used to be plugged and matched with the positioning member 27. Specifically, the positioning member 27 refers to a component with a certain length, and the positioning member 27 is arranged on the inner wall of the grain bowl slot 21, and the positioning members 27 are arranged along the insertion direction of the first plug-in portion 41. When the first plug-in portion 41 is inserted into the grain bowl slot 21, the positioning member 27 is also inserted into the positioning hole 43 on the first plug-in portion 41. The positioning member 27 can cooperate with the positioning hole 43 to make the grain bowl assembly 2 and the limiting member 4 more firmly fixed.

[0058] In an alternative embodiment, see Figure 4 and Figure 6 There can be multiple positioning members 27, which are spaced apart from each other. There can also be multiple positioning holes 43 on the first plug-in portion 41, and the positions of the positioning holes 43 match the positioning members 27, which further improves the positioning accuracy.

[0059] In one embodiment, see Figure 3 The distance between the upper wall of the first plug-in portion 41 and the inner wall of the grain bowl slot 21 in the vertical direction is 0.5 mm to 2 mm. Specifically, the distance between the first plug-in portion 41 and the inner wall of the grain bowl slot 21 includes but is not limited to Figure 3 The spacing between the upper wall of the first plug-in portion 41 and the inner wall of the grain bowl slot 21 is set to 0.5 mm to 2 mm in the vertical direction, so as to ensure that the first plug-in portion 41 is inserted into the grain bowl slot 21 to a depth that can prevent the first plug-in portion 41 from supporting the grain bowl assembly 2.

[0060] In one embodiment, see Figure 4 The grain bowl assembly 2 includes an upper shell 22, a bottom shell 23 and a grain bowl 24. The upper shell 22 covers the mouth of the bottom shell 23. The weighing unit 3 is arranged between the upper shell 22 and the bottom shell 23. The grain bowl slot 21 is recessed on the bottom shell 23. The upper shell 22 has a receiving groove recessed toward the bottom shell 23, and the grain bowl 24 is arranged in the receiving groove. Specifically, the upper shell 22 and the bottom shell 23 both refer to shell-shaped components. The upper shell 22 covers the mouth of the bottom shell 23, and the grain bowl slot 21 is recessed on the bottom shell 23. The grain bowl 24 refers to a bowl-shaped container for accommodating pet food. The upper shell 22 is also provided with a receiving groove recessed toward the bottom shell 23, and the grain bowl 24 can be placed in the receiving groove. The weighing unit 3 is arranged between the upper shell 22 and the bottom shell 23. The supporting effect of the weighing unit 3 can make the upper shell 22 have freedom in the vertical direction relative to the bottom shell 23, and the pet food in the food bowl 24 can be weighed, making the use of the entire food bowl assembly 2 more convenient.

[0061] In one embodiment, see Figure 7 and Figure 8 The upper shell 22 is provided with a first fixing portion 25, which is used to fix at least part of the weighing unit 3. The bottom shell 23 is also provided with a second fixing portion 26, which is used to fix another part of the weighing unit 3.

[0063] In one embodiment, see Figure 2The main body 1 includes a grain storage bin 11, a grain outlet channel 12, and a discharging assembly 13. The grain storage bin 11 is used to contain grains. The discharging assembly 13 is used to transport the grains in the grain storage bin 11 to the grain outlet channel 12. The grain outlet channel 12 is used to transport the grains to the outside of the main body 1, and the grain bowl assembly 2 is located below the outlet of the grain outlet channel 12. Specifically, the grain bowl assembly 2 is connected to the main body 1 through a limiter 4, and the weighing unit 3 is electrically connected to the control circuit inside the main body 1 through an electrical connection assembly 5. When it is necessary to put grain into the grain bowl assembly 2, the processor in the main body 1 controls the discharging assembly 13 to start, transport the pet grains in the grain storage bin 11 to the grain outlet channel 12, and transport them to the grain bowl assembly 2 through the grain outlet channel 12. At this time, the weighing unit 3 on the grain bowl assembly 2 will weigh the pet grains and send the detected weight data to the processor. The processor can upload the weight data of the grain to the server through the network and send it to the user. The processor can also control the discharging component 13 to stop working when the grain in the grain bowl component 2 reaches a specified weight, thereby completing the feeding operation of the pet food.
