Description

Technical Field

[0001] This utility model relates to the field of pet feeding equipment technology, specifically to an intelligent feeder. Background Technology

[0002] With the continuous improvement of living standards, pets have become important members of many families, especially small animals such as cats, dogs, and hamsters. At the same time, intelligent pet feeders have emerged, bringing a brand new change to modern pet ownership. They can intelligently solve feeding problems caused by busy work, temporary travel, or differences in work and rest schedules. Through precise timed feeding functions, owners no longer need to worry about their pets going hungry at home.

[0003] Currently, most smart feeders on the market use a quantitative rotating food dispensing box design for their food dispensing mechanism. This design typically consists of a rotating disc with several quantitative cavities and a fixed food outlet. During operation, the motor drives the rotating disc to rotate. When a quantitative cavity rotates to the bottom of the food bin, it is filled with pet food. Subsequently, the cavity rotates to the top of the food outlet, and the pet food falls into the food bowl under the action of gravity, thus achieving quantitative food dispensing.

[0004] However, in actual use, it was found that after long-term use, the oil, crumbs, and powder left over from the pet food falling into the rotary food dispenser easily adhere to the inner wall and crevices of the rotating disc, breeding bacteria and even mold, which seriously affects the pet's dietary health. Furthermore, during the continuous rotation of the disc, the falling residue can also enter the connection between the disc and the motor-driven shaft, increasing the resistance to rotation, reducing the lifespan of the device, and making maintenance inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent feeder to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An intelligent feeder includes a grain storage bin, a grain discharge bin, a receiving tray, and a spiral tube conveyor. The grain discharge bin is equipped with a battery and a control circuit board. A splicing assembly is located inside the grain discharge bin. The spiral tube conveyor is located inside the splicing assembly. A guide assembly is located inside the splicing assembly. A first discharge port is opened on the left side of the grain discharge bin. A receiving tray is placed inside the receiving tray. A weighing sensor is installed between the receiving tray and the receiving tray.

[0008] The splicing assembly includes a mounting plate and a cover plate. The mounting plate is located inside the grain silo, and the battery and control circuit board are located below the mounting plate. The spiral tube conveyor is located on top of the mounting plate. A second discharge port is located at the bottom of the mounting plate. The discharge pipe of the spiral tube conveyor is located inside the discharge port. A connecting pipe is located inside the cover plate. The bottom of the connecting pipe is attached to the top of the feed pipe of the spiral tube conveyor. The grain outlet of the grain storage silo is connected to the internal thread of the connecting pipe.

[0009] The guiding assembly includes a guide plate located below the discharge port, with the other end located inside the first discharge port;

[0010] The battery is electrically connected to the control circuit board, the spiral tube conveyor, and the weighing sensor, and the control circuit board is electrically connected to the spiral tube conveyor and the weighing sensor.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the splicing assembly also includes a first mounting post, a first plug-in rod, a second mounting post, and a second plug-in rod. There are multiple first mounting posts, first plug-in rods, second mounting posts, and second plug-in rods. All first mounting posts are fixedly installed on the bottom of the inner wall of the grain silo. All first plug-in rods are fixedly installed on the bottom of the mounting plate and are plugged into all first mounting posts respectively. All second mounting posts are fixedly installed on the top of the mounting plate. All second plug-in rods are fixedly installed on the bottom of the cover plate and are plugged into all second mounting posts respectively.

[0013] Furthermore, two limiting blocks are fixedly installed on the top of the mounting plate, and the opposite sides of the two limiting blocks are respectively attached to the front and rear sides of the spiral tube conveyor base.

[0014] Furthermore, a charging interface is provided on the right side of the grain outlet, and a wire groove is provided on the top of the mounting plate.

[0015] Furthermore, the guide assembly also includes two isolation plates, which are fixedly connected to the front and rear sides of the guide plate respectively, and the two isolation plates are slidably connected to the bottom of the mounting plate.

[0016] Furthermore, both of the isolation plates and the inner wall of the grain silo are provided with mounting grooves on the left side. A first magnet is embedded in the mounting groove on the left side, and a second magnet is embedded in the mounting groove on the right side.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0018] The spiral conveyor system eliminates the risk of debris from pet food falling from the food bin into the rotating shaft and motor. The spiral blades rotate in a sealed environment, confining debris within the sealed space and pushing it out with the food. The debris is then discharged through the second outlet via the discharge pipe, preventing leakage to the transmission components. This greatly improves the long-term stability and reliability of the equipment, extends its service life, and facilitates disassembly and cleaning of the spiral conveyor's interior during later maintenance.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-9 As shown, this utility model provides an intelligent feeder, including a grain storage bin 1, a grain dispensing bin 2, a receiving tray 3, and a spiral tube conveyor 7. The grain dispensing bin 2 is equipped with a battery 4, a control circuit board 5, and a splicing assembly 6. The spiral tube conveyor 7 is located inside the splicing assembly 6, and a guide assembly 8 is located inside the splicing assembly 6. A first discharge port 9 is opened on the left side of the grain dispensing bin 2. A receiving tray 10 is placed inside the receiving tray 3, and a weighing sensor 11 is arranged between the receiving tray 3 and the receiving tray 10.

[0032] The splicing assembly 6 includes a mounting plate 601 and a cover plate 602. The mounting plate 601 is located inside the grain silo 2, and the battery 4 and control circuit board 5 are located below the mounting plate 601. The spiral tube conveyor 7 is located on top of the mounting plate 601. A second discharge port 603 is located at the bottom of the mounting plate 601. The discharge pipe of the spiral tube conveyor 7 is located inside the discharge port 603. A connecting pipe 604 is located inside the cover plate 602. The bottom of the connecting pipe 604 is attached to the top of the feed pipe of the spiral tube conveyor 7. The grain outlet of the grain storage silo 1 is threadedly connected to the inside of the connecting pipe 604.

[0033] The guide assembly 8 includes a guide plate 801, which is located below the discharge port 603 and has its other end located inside the first discharge port 9;

[0034] The battery 4 is electrically connected to the control circuit board 5, the spiral tube conveyor 7, and the weighing sensor 11, and can be used to provide the power required for the operation of each power module. The control circuit board 5 is electrically connected to the spiral tube conveyor 7 and the weighing sensor 11. As the control core of the system, the control circuit board 5 is used to receive the weight signal collected in real time by the weighing sensor 11, and according to the preset feeding amount logic judgment result (this feeding amount can be operated by the user through the app on the mobile phone. This intelligent control method is already a well-known technology in this field, so it will not be described in detail), it sends start, stop and speed control commands to the spiral tube conveyor 7, thus forming a complete closed-loop precision feeding control system. The spiral tube conveyor 7 is driven by a stepper motor and is controlled by the control circuit board 5.

[0035] The stepper motor adopts an intermittent drive mode of "10 steps forward and 8 steps back". Specifically, the stepper motor drives the spiral rod inside the spiral tube conveyor 7 to rotate, so that the spiral blades advance by 10 steps to convey a fixed amount of pet food; then immediately rotates in the opposite direction by 8 steps to make the spiral rod retract. This can effectively solve the problem of food blockage formed during the conveying process, significantly reduce the risk of food jamming, and ensure smooth food dispensing.

[0036] Furthermore, a drying chamber (not shown in the figure) is also provided inside the food storage bin 1 during use to ensure the dryness of the pet food in the food storage bin 1 and avoid moisture. When the pet food is discharged at a fixed time and place, the spiral tube conveyor 7 starts to work. During the process of moving the pet food, the pet food in the food storage bin 1 enters the spiral tube conveyor 7 through the connecting pipe 604 to replenish the pet food. Then, under the action of the discharge port 603, it falls onto the inclined guide plate 801, so that the pet food rolls into the receiving tray 10 for weighing.

[0037] The splicing component 6 also includes a first mounting post 605, a first plug-in rod 606, a second mounting post 607, and a second plug-in rod 608. There are several first mounting posts 605, first plug-in rods 606, second mounting posts 607, and second plug-in rods 608. All first mounting posts 605 are fixedly installed on the bottom of the inner wall of the grain silo 2. All first plug-in rods 606 are fixedly installed on the bottom of the mounting plate 601 and are plugged into all first mounting posts 605 respectively. All second mounting posts 607 are fixedly installed on the top of the mounting plate 601. All second plug-in rods 608 are fixedly installed on the bottom of the cover plate 602 and are plugged into all second mounting posts 607 respectively.

[0038] With this setup, when the mounting plate 1 is installed, the first insertion rod 606 at the bottom is inserted into the first mounting column 605 to complete the initial fixation. Then, the spiral tube conveyor 7 is initially installed by connecting the bottom discharge pipe to the discharge port 603. Subsequently, the cover plate 602 is installed by inserting the second insertion rod 608 at the bottom of the cover plate 602 into the upper second mounting column 607, thus forming protection for the internal components of the grain bin 2.

[0039] Two limiting blocks 12 are fixedly installed on the top of the mounting plate 601, and the opposite sides of the two limiting blocks 12 are respectively attached to the front and rear sides of the base of the spiral tube conveyor 7.

[0040] With this configuration, when installing the spiral conveyor 7, the front and rear sides of the base of the spiral conveyor 7 are restricted by the two limiting blocks 12, thereby completing further fixation and ensuring the stability of the spiral conveyor 7 during use.

[0041] A charging interface 13 is provided on the right side of the grain outlet 2, and a wire groove 14 is provided on the top of the mounting plate 601.

[0042] This setup facilitates the supply of power to battery 4, ensuring the normal operation of the spiral conveyor 7 even during a power outage at home, thus preventing food shortages.

[0043] The guide assembly 8 also includes two isolation plates 802, which are fixedly connected to the front and rear sides of the guide plate 801 respectively, and the two isolation plates 802 are slidably connected to the bottom of the mounting plate 601.

[0044] This design uses two partition plates 802 to protect the left and right sides of the guide plate 801, preventing pet food from falling into the food dispensing bin 2 during its rolling descent. Furthermore, during the installation of the guide component 8 along with the mounting plate 601, the partition plates 802 are slid to move the guide plate 801 to the right side. After the mounting plate 601 is installed, the pull grooves on opposite sides of the two partition plates 802 change the position of the guide plate 801, allowing pet food rolling off the guide plate 801 to fall into the food collection tray 10.

[0045] Among them, the two isolation plates 802 and the inner left side of the grain bin 2 are provided with installation grooves 15. The first magnet 16 is embedded in the inside of the left installation groove 15, and the second magnet 17 is embedded in the inside of the right installation groove 15.

[0046] With this configuration, after the guide plate 801 is pulled into place by the isolation plate 802, the stability of the guide plate 801 is ensured during long-term use due to the attraction between the first magnet 16 and the second magnet 17.
