[0002] Previously, the power supply for the portable cat litter box was based on the built-in battery of the portable unit, which could only be charged through the power contacts when it was moved to the initial position. The battery power of the main unit was limited and could not effectively ensure that the main unit could operate normally all the time. Alternatively, the main unit was used to drag the power cord for power supply. This method could result in the power cord getting tangled, and the protruding power cord could attract cats to chew on it and break. The length of the power cord could not be adjusted according to the distance the main unit moved on the litter box. Utility Model Content

[0003] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a device for retracting and extending the power cord of a flat-shovel type electric cat litter box.

[0004] The technical solution adopted by this utility model is as follows: It includes a base box, inside which a large wire roller is rotatably mounted. An FPC is wound around the circumference of the large wire roller. The interior of the large wire roller is divided into an upper space and a lower space by a small wire roller partition. A small wire roller is located in the upper space. One end of the FPC is fixedly connected to the small wire roller, and the other end is pulled out and connected to the base box. A spiral spring is located in the lower space for resetting the large wire roller after rotation. A cover is provided on the top of the base box, and a power supply component electrically connected to the small wire roller is located inside the cover.

[0005] As a preferred embodiment of this utility model, the bottom of the large thread roller is rotatably connected to the bottom of the base box, a positioning post is fixedly provided inside the base box, the positioning post is located at the center of the bottom of the large thread roller, one end of the spiral spring is fixedly connected to the circumference of the positioning post, and the other end is fixedly connected to the inner ring of the large thread roller.

[0006] As a preferred embodiment of this utility model, a limiting part is formed on the top of the bottom box, and an installation partition is installed in the limiting part. The small line roller is fixedly installed on the installation partition, and one end of the small line roller extends into the upper space.

[0007] As a preferred embodiment of the present invention, the FPC includes a first FPC and a second FPC connected to each other, the width of the first FPC is greater than the width of the second FPC, the first FPC is wound around the circumference of the large wire roller, and the second FPC is wound around the circumference of the small wire roller.

[0008] As a preferred embodiment of the present invention, a notch is formed on the large line roller, and the connection between the first FPC and the second FPC is fixedly connected to the notch.

[0009] As a preferred embodiment of this invention, the power supply assembly includes:

[0010] An FPC adapter plate is fixedly connected to the top of the small line roller, and the FPC adapter plate is electrically connected to the first FPC and the second FPC respectively through the small line roller;

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model is a device for retracting and extending the power cord of a flat-shovel type electric cat litter box. By using a winding and extending power cord method to replace the main unit's built-in battery, it achieves continuous power supply to the main unit and ensures the stability of the main unit's working state. Specifically, by setting a rotatable large cord roller in the bottom box and winding the FPC around the large cord roller, the actual length of the FPC can be pulled out according to the movement distance of the main unit. At the same time, a spiral spring is set inside the large cord roller to drive the large cord roller to reset after rotation, so as to retract the FPC in the bottom box at the point of being pulled out. This allows the FPC in the bottom box to be pulled out according to the actual length of use, avoiding the accumulation of excessively long FPC around the cat litter box, preventing cats from tearing the FPC, improving the service life of the power cord device and the overall aesthetics.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] The following is combined with Figure 1-4This invention describes a device for retracting and extending the power cord of a flat-shovel type electric cat litter box. The device includes a base box 1. A large cord roller 13 is rotatably mounted inside the base box 1. An FPC 112 is wound around the circumference of the large cord roller 13. The FPC 112 is housed within the base box 1 and wound around the large cord roller 13. The rotation of the large cord roller 13 allows the FPC 112 to be pulled out and extended within the base box 1. The large cord roller 13 is divided into an upper space 11 and a lower space 12 by a small cord roller partition 14. The upper space 11 is used for connecting... The circuit assembly includes a lower space 12 for the rotation of the large wire roller 13 and its subsequent reset rotation. The upper space 11 contains a small wire roller 111. One end of the FPC 112 is fixedly connected to the small wire roller 111, and the other end is pull-out connected to the base box 1. A section of FPC 112 is wound around the small wire roller 111 to prevent the FPC 112 from being affected by the rotation of the large wire roller 13, thus preventing the FPC 112 in the upper space 11 from jamming the large wire roller 13 and preventing it from rotating. A spiral spring 122 is provided in the lower space 12. The spiral spring 122 is used to reset the large wire roller 13 after rotation. One end of the spiral spring 122 is fixedly connected to the large wire roller 13, and the other end is connected to the positioning post 121 fixedly provided in the bottom box 1. When the large wire roller 13 rotates, it drives the spiral spring 122 to coil or unwind. The spiral spring 122 is in the FPC112 pulled-out state when it is coiled, and it stores energy when it is coiled. When the external force stops pulling the FPC112 outward, the elastic potential energy stored in the spiral spring 122 forces the large wire roller 13 to rotate, thereby realizing the reset of the FPC112. The recycling and storage of FPC112 allows FPC112 to be stored and retracted according to the specific location of the host 4, effectively preventing excessively long FPC112 from piling up on the litter box and preventing cats from tearing or biting the FPC112. The top of the base box 1 is provided with a cover 2, and the cover 2 is provided with a power supply component 21 that is electrically connected to the small wire roller 111. The power supply component 21 is used to connect FPC112 and the litter box host 4 to provide power to the host 4. FPC112 is a prior art flexible circuit board.

[0026] Please refer to Figures 2-3As shown, the bottom of the large wire roller 13 is rotatably connected to the bottom of the base box 1. A positioning post 121 is fixedly provided inside the base box 1. The positioning post 121 is located at the center of the bottom of the large wire roller 13. One end of the spiral spring 122 is fixedly connected to the circumference of the positioning post 121, and the other end is fixedly connected to the inner ring of the large wire roller 13. The positioning post 121 passes through the bottom of the large wire roller 13 and is fixedly connected to the base box 1. The small wire roller 111 is used to fixally connect one end of the spiral spring 122. Since the other end of the spiral spring 122 is fixedly connected to the large wire roller 13, when the large wire roller 13 rotates clockwise, the spiral spring 122 gradually tightens into the positioning post 121. At this time, the FPC 112 wound on the large wire roller 13 is pulled out to the outside of the base box 1, and the spiral spring 122 stores elastic potential energy and is used for the reset rotation of the large wire roller 13 to realize the reset and rewinding of the FPC 112.

[0027] Please refer to Figures 2-3 As shown, a limiting part 15 is formed on the top of the bottom box 1. An installation partition 3 is installed in the limiting part 15. The installation partition 3 is limited and installed on the bottom box 1, so that the installation partition 3 and the bottom box 1 support cannot rotate. The small wire roller 111 is fixedly installed on the installation partition 3, and one end of the small wire roller 111 extends into the upper space 11. The small wire roller 111 can be used to wind the FPC 112, so that one end of the output circuit of the FPC 112 remains stationary in the upper space 11.

[0028] Please refer to Figures 2-3 As shown, the FPC112 includes a first FPC1121 and a second FPC1122 connected to each other. The width of the first FPC1121 is greater than the width of the second FPC1122. The first FPC1121 is wound around the circumference of the large wire roller 13, and the second FPC1122 is wound around the circumference of the small wire roller 111. The first FPC1121 is wound on the large wire roller 13, and the second FPC1122 is wound on the small wire roller 111. When the first FPC1121 is pulled out of the bottom box 1, the large wire roller 13 will drive the first FPC1121 and the second FPC1122. The rotation is achieved by winding a second FPC1122 onto the small wire roller 111 in the upper space 11, ensuring that the length of the second FPC1122 can be wound onto the small wire roller 111. This prevents the large wire roller 13 from being unable to rotate due to the length of the second FPC1122. When the first FPC1121 is pulled outward, the second FPC1122 is wound up to avoid affecting the rotation of the large wire roller 13. Conversely, when the first FPC1121 is reset and stored in the bottom box 1, the second FPC1122 is unfolded to provide sufficient length for the next outward pull of the FPC112 adapter plate.

[0029] Please refer to Figure 3 As shown, a notch 131 is formed on the large thread roller 13. The connection between the first FPC 1121 and the second FPC 1122 is fixedly connected to the notch 131. The limiting notch 131 is used to fix one end of the first FPC 1121 and one end of the second FPC 1122, respectively realizing the winding of the first FPC 1121 on the large thread roller 13 and the winding of the second FPC 1122 on the small thread roller 111.

[0030] Please refer to Figures 1-4 As shown, the power supply assembly 21 includes:

[0031] FPC adapter plate 211 is fixedly connected to the top of the small wire roller 111. FPC adapter plate 112 is electrically connected to the first FPC 1121 and the second FPC 1122 respectively through the small wire roller 111. FPC adapter plate 211 is used for electrical connection with FPC 112.

[0032] DC socket 212 is connected to the cover 2 and electrically connected to the FPC adapter board 211. DC socket 212 is fixedly installed on the cover 2 for external power supply access. At the same time, the other end of DC socket 212 is electrically connected to FPC adapter board 211.

[0033] The plug adapter board 213 is connected to the end of the second FPC1122 away from the first FPC1121. The plug adapter board 213 is used to transmit external power to the litter box host 4.

[0034] Please refer to Figure 1 As shown, the plug adapter plate 213 is provided with a DC plug 214. The DC plug 214 is electrically connected to the second FPC1122 through the plug adapter plate 213. The DC plug 214 can be plugged into the host 4 to realize the transmission of external power.

[0035] Please refer to Figures 1-3 As shown, the cover 2 is provided with mounting bolts 22, which are used for the fixed installation between the bottom box 1 and the cover 2. At the same time, by increasing the length of the mounting bolts 22, the bottom box 1 can be fixedly installed on the cat litter box.

[0036] Working principle of this utility model:

[0037] The power cord retraction device is fixedly installed at one end of the litter box, and the DC plug 214 is plugged into the litter box main unit 4, and the external power supply is plugged into the DC socket 212 to power the main unit 4.

[0038] In the initial state, the main unit 4 is located on the side of the cat litter box that is close to the power cord retraction device. At this time, the spiral spring 122 is in the unfolded state in the lower space 12, and the first FPC 1121 is wound up onto the large cord roller 13, while the second FPC 1122 is in the unfolded state on the small cord roller 111.

[0039] When FPC112 is pulled outwards to its furthest point (e.g.) Figure 4 As shown), under the drive of the drive component, the host 4 gradually moves away from the power cord retraction device. The movement of the host 4 causes the FPC to be pulled out of the bottom box 1. The pulling out of the FPC forces the large wire roller 13 to rotate along the bottom of the bottom box 1. While the large wire roller 13 is rotating, since one end of the spiral spring 122 is fixedly connected to the inner ring of the large wire roller 13 and the other end is fixedly connected to the positioning post 121, and the positioning post 121 is fixedly installed on the bottom box 1, the rotation of the large wire roller 13 ultimately causes the spiral spring 122 to be wound up and stored in a state of tension. At this time, the second FPC 1122 on the small wire roller 111 is wound up under the drive of the large wire roller 13 to avoid the second FPC 1122 affecting the rotation of the large wire roller 13.

[0040] When the main unit 4 moves to the farthest end of the litter box and resets, the main unit 4 drives the FPC112 to reset. Since the spiral spring 122 stores elastic potential energy for FPC rewinding and resetting when it moves to the farthest end, the spiral spring 122 gradually unfolds outward, driving the large line roller 13 to rotate and rewinding the first FPC1121 on the large line roller 13 into the bottom box 1. The second FPC1122 is also retracted and wound onto the small line roller 111.

[0041] The first FPC1121 and the second FPC1122 are electrically connected to each other, and their connection is fixedly connected to the notch 131 of the large wire roller 13. One end of the first FPC1121 is connected to the plug adapter plate 213, the DC plug 214 and the host 4 in sequence, and one end of the second FPC1122 is connected to the small wire roller 111, the FPC adapter plate 211, the DC socket 212 and the external power supply in sequence to provide power to the host 4. The power transmission line can be wound up and unwound according to the movement of the host 4.
