Description

Technical Field

[0001] This utility model relates to the field of pet feeder technology, and more specifically, to a transmission mechanism for adjusting the amount of food in an automatic pet feeder. Background Technology

[0002] As people's living standards continue to improve, pet feeding has become a demand. In order to provide pets with a comfortable living environment, various pet supplies have emerged, including an automatic pet feeder.

[0003] Patent application number 202420558462.4 discloses an automatic pet feeder, including a quantitative feeding component, a feed dispensing component mounted on the quantitative feeding component, and a feed storage component mounted on the quantitative feeding component. The quantitative feeding component includes a transfer tube, a housing located at one end of the transfer tube, a core rod movably installed inside the housing, a partition fixedly installed on the inner end of the core rod, and a spring connecting the core rod and the housing. By controlling the pad to stretch outward until the core rod compresses the spring, as the partition is removed from the top end of the transfer tube, the food can fall smoothly into the pipe at the bottom of the transfer tube. When the pad is released, the compressed spring pushes the inner end of the core rod and the food into the inner cavity of the feed hopper. At this time, the device can avoid the problems of difficulty in adjusting the amount of food added by automatic equipment and the easy for the food to be pushed to the ground by the pet's head.

[0004] Regarding the aforementioned technologies, by controlling the pad to stretch outward until the core rod compresses the spring, as the partition is removed from the top end of the transfer pipe, the food can fall smoothly into the bottom pipe of the transfer pipe, achieving the effect of feeding food. However, this device requires manual pulling of the pad and does not have an autonomous feeding function, which reduces the applicability of the equipment. Summary of the Invention

[0005] To solve the above problems, this utility model provides a transmission mechanism for adjusting the food quantity of an automatic pet feeder, adopting the following technical solution: An automatic pet feeder's food quantity adjustment transmission mechanism includes a base and a housing disposed on top of the base. A can is disposed on top of the housing, with the bottom end of the can sliding through into the housing. A control panel is disposed on one side of the housing, and an inlet / outlet is disposed on the side of the housing away from the control panel. A sealing plate is hinged inside the inlet / outlet. A cover plate is disposed on the top of the can, with a sealing gasket at the bottom end of the cover plate. An insertion assembly is disposed between the can and the housing. A first conveying assembly is disposed inside the can. A weighing hopper is disposed inside the housing, with a feeding pipe connected to the bottom end of the weighing hopper. A conveying groove is disposed inside the base. Feeding grooves are disposed on the top of the base and the bottom of the housing, and the feeding grooves and conveying grooves are connected. The feeding pipe slides within the feeding groove and is equipped with a sealing assembly. A weighing assembly is disposed between the weighing hopper and the inner wall of the bottom end of the housing. A second conveying assembly is disposed within the conveying groove. A placement groove is disposed on one side of the base, below the conveying groove, and a placement basin is disposed within the placement groove.

[0006] By adopting the above technical solution, when using the equipment, the bottom of the base is equipped with suction cups. The user places the equipment in a suitable position, and the suction cups attract the ground, which helps to maintain the stability of the equipment. The operator places the can inside the shell and assembles the can and shell using the plug-in components. The user lifts the cover plate on the top of the can and pours the pet food into the can. After the pet food is placed, the user places the cover plate on top of the can. The bottom of the cover plate is equipped with a sealing gasket. The user places the sealing gasket inside the can, and the friction generated between the sealing gasket and the inner wall of the can secures the cover plate.

[0007] After the pet food is added, the control panel on the side wall of the container sets the feeding time and quantity. When a small amount of food is needed, the first conveying component transports the pet food from inside the container to the weighing hopper. The weighing hopper is equipped with a sealing component to prevent the pet food from falling. Under the weight of the pet food, the weighing hopper moves downward, pushing the feeding pipe to slide within the feeding trough. The cooperation between the feeding trough and the feeding pipe helps maintain the stability of the weighing hopper's movement. When the weighing hopper descends, it contacts the weighing component, which determines the weight of the pet food in the weighing hopper, facilitating accurate feeding. Once the weight of the pet food is determined, the first conveying component operates, opening the feeding pipe port through the sealing component, allowing the pet food to enter the conveying trough through the feeding trough. Subsequently, the second conveying component discharges the pet food from the conveying trough port, where it falls into the placement basin, thus completing the feeding process.

[0008] Furthermore, the mating assembly includes two insert blocks disposed on the upper side wall of the tank body, and a slot is provided at the top of the housing to match the insert blocks. The insert blocks and the slot on the same side are fixed together by bolts.

[0009] By adopting the above technical solution, the user places the tank inside the shell, so that the insert block installed on the side wall of the tank and the slot opened on the top of the shell engage. The cooperation between the insert block and the slot serves to position and fix the tank. Then, the bolts are threaded through the screw groove opened on the bottom of the insert block and the slot on the same side, which helps to maintain the stability of the tank installation. Through the cooperation of the insert block, slot and bolt, the tank and the shell are separated, which makes it easy for the user to disassemble and clean the tank later.

[0010] Furthermore, the first conveying assembly includes a protective box disposed inside the tank. Multiple connecting rods arranged in a ring array are fixedly installed between the side wall of the protective box and the inner wall of the tank. A second geared motor is disposed inside the protective box. A support rod is rotatably mounted at the bottom of the protective box. A first spiral blade is fixedly sleeved on the lower side wall of the support rod. The top of the support rod penetrates into the protective box and is fixedly connected to the end of the output shaft of the second geared motor. A heat-conducting ring is sleeved on the side wall of the protective box.

[0011] By adopting the above technical solution, the second geared motor drives the support rod to rotate, and the support rod drives the first spiral blade to rotate, thereby slowly feeding the pet food inside the can, achieving the function of feeding. The first spiral blade is made of rubber, which helps to prevent the pet food from being damaged when the first spiral blade rotates.

[0012] Furthermore, the sealing assembly includes a rotating rod rotatably installed inside the feed tube, a limiting plate fixedly sleeved on the side wall of the rotating rod, a support plate fixedly installed on the side wall of the feed tube, a first reduction motor fixedly installed at the top of the support plate, a drive gear fixedly sleeved on the side wall of the output shaft of the first reduction motor, the rotating rod rotatably passes through the feed tube at one end near the support plate, and a driven gear is fixedly sleeved on the side wall of the end of the rotating rod passing through the feed tube, the driven gear meshing with the drive gear.

[0013] By adopting the above technical solution, a limiting plate is provided inside the feeding pipe. The limiting plate blocks the feeding pipe, making it easier for pet food to fall into the weighing hopper for subsequent weighing. When the weight of pet food in the weighing hopper reaches the preset weight, the first reduction motor drives the drive gear to rotate, the drive gear drives the driven gear to rotate, the driven gear drives the rotating rod to rotate, and the rotating rod drives the limiting plate to rotate, thereby opening the feeding pipe port and allowing the pet food to enter the conveying trough through the feeding trough.

[0014] Furthermore, the weighing assembly includes a pressing ring fixedly sleeved on the side wall of the lower section of the feeding pipe, and multiple pillars arranged in a ring array fixedly installed on the side wall of the weighing hopper. Springs are fixedly connected between the bottom end of the pillars and the inner wall of the bottom end of the housing. Multiple gravity sensors arranged in a ring array are provided on the inner wall of the bottom end of the housing, and the gravity sensors are located below the pressing ring.

[0015] By adopting the above technical solution, when pet food falls into the weighing hopper, the weighing hopper moves downward under the action of the weight of the pet food to compress the spring. The weighing hopper, along with the feeding tube and the pressing ring, descends synchronously, causing the pressing ring to contact the top of the gravity sensor. By pressing the gravity sensor with the pressing ring, the weight of the pet food inside the weighing hopper can be measured. When the weight of the pet food in the weighing hopper reaches the preset value, the injection of pet food into the weighing hopper can be stopped.

[0016] Furthermore, the second conveying assembly includes a transmission rod rotatably mounted in the conveying trough, a second spiral blade fixedly sleeved on the side wall of the transmission rod, an mounting box fixedly mounted on the side of the base away from the transmission rod, a third geared motor fixedly mounted inside the mounting box, a baffle hinged to the side of the base away from the mounting box, the transmission rod rotatably passing through the base and extending into the mounting box on the side away from the baffle, and one end of the transmission rod passing through the mounting box being fixedly connected to the end of the output shaft of the third geared motor.

[0017] By adopting the above technical solution, after the weighed pet food falls into the conveying trough, the third reduction motor drives the transmission rod to rotate, which in turn drives the second spiral blade to rotate. Under the driving force of the second spiral blade, the pet food is discharged through the conveying trough and falls into the placement basin, thus serving as feeding. A baffle is hinged at the port of the conveying trough, which acts as a barrier. When feeding is needed, the second spiral blade drives the pet food to move, and the baffle can be opened by the push of the pet food, facilitating the falling of the pet food. The second spiral blade is made of rubber, which helps to reduce the damage to the pet food when the second spiral blade rotates.

[0018] Furthermore, the inner wall of the placement basin is provided with inclined blocks, and multiple positioning rods arranged in an arc array are fixedly installed on the side wall of the placement basin. The inner wall of the placement groove is provided with positioning grooves that match the positioning rods, and rubber sleeves are fixedly fitted on the side walls of the positioning rods.

[0019] By adopting the above technical solution, the basin is placed in the placement groove, which can then be used to install the basin. The side wall of the basin is provided with a positioning rod, which engages with the positioning groove opened in the inner wall of the placement groove to further position the basin. The side wall of the positioning rod is provided with a rubber sleeve, which helps to increase the friction between the positioning rod and the positioning groove, thereby helping to maintain the stability of the basin. Through the cooperation of the positioning rod and the positioning groove, the basin and the base are set separately, making it easy for users to disassemble the basin for cleaning.

[0020] In summary, this utility model has the following beneficial technical effects: (1) In this utility model, the first conveying component facilitates the discharge of pet food from the tank. The sealing component and the weighing component can weigh the pet food, making it easier for the equipment to automatically and quantitatively feed the pet food. The value of the weighing component can be changed by the control panel, making it easier for the equipment to change the amount of pet food fed.

[0021] (2) In this utility model, the tank and the shell are set separately, which makes it convenient for users to disassemble the tank for cleaning. The basin and the base are fixed by the positioning rod and the positioning groove. The side wall of the positioning rod is provided with a rubber sleeve, which helps to increase the friction between the positioning rod and the positioning groove, thereby helping to maintain the stability of the basin. Through the cooperation of the positioning rod and the positioning groove, the basin and the base are set separately, which makes it convenient for users to disassemble the basin for cleaning.

The friction generated between the sealing gasket and the inner wall of the can 3 can fix the cover plate.

[0030] The tank body 3 is equipped with a first conveying assembly, which includes a protective box 23 disposed inside the tank body 3. Multiple connecting rods arranged in a ring array are fixedly installed between the side wall of the protective box 23 and the inner wall of the tank body 3. A second reduction motor 24 is disposed inside the protective box 23. A support rod 25 is rotatably installed at the bottom of the protective box 23. A first spiral blade 26 is fixedly sleeved on the lower side wall of the support rod 25. The top end of the support rod 25 penetrates into the protective box 23 and is fixedly connected to the end of the output shaft of the second reduction motor 24. A heat-conducting ring is sleeved on the side wall of the protective box 23.

[0031] After the pet food is added, the time and amount of food can be set through the control panel on the side wall of the shell 2. When a small amount of food is needed, the second reduction motor 24 drives the support rod 25 to rotate, and the support rod 25 drives the first spiral blade 26 to rotate, thereby slowly feeding the pet food inside the can 3 to achieve the purpose of feeding. The first spiral blade 26 is made of rubber, which helps to prevent the pet food from being damaged when the first spiral blade 26 rotates.

[0032] The housing 2 is equipped with a weighing hopper 11, and the bottom end of the weighing hopper 11 is connected to a feeding pipe 16. The base 1 is equipped with a conveying groove 5.

A limiting plate 27 is fixedly sleeved on the side wall of the rotating rod 15. A support plate 18 is fixedly installed on the side wall of the feeding pipe 16. A first reduction motor 20 is fixedly installed at the top of the support plate 18. A drive gear 19 is fixedly sleeved on the side wall of the output shaft of the first reduction motor 20. The rotating rod 15 rotates through the feeding pipe 16 at the end near the support plate 18. A driven gear 17 is fixedly sleeved on the side wall of the end of the rotating rod 15 that passes through the feeding pipe 16. The driven gear 17 and the drive gear 19 mesh.

[0033] A weighing assembly is provided between the weighing hopper 11 and the inner wall of the bottom end of the housing 2. The weighing assembly includes a pressing ring 21 fixedly sleeved on the side wall of the lower section of the feeding pipe 16. Multiple support columns 12 arranged in a ring array are fixedly installed on the side wall of the weighing hopper 11. Springs 13 are fixedly connected between the bottom end of the support column 12 and the inner wall of the bottom end of the housing 2. Multiple gravity sensors 22 arranged in a ring array are provided on the inner wall of the bottom end of the housing 2. The gravity sensors 22 are located below the pressing ring 21.

[0034] Pet food falls from the bottom of can 3 into weighing hopper 11. Under the weight of the pet food, weighing hopper 11 moves downwards, compressing spring 13. Weighing hopper 11, along with the feed pipe 16 and pressing ring 21, descends synchronously, causing pressing ring 21 to contact the top of gravity sensor 22. Pressing gravity sensor 22 by pressing ring 21 measures the weight of the pet food inside weighing hopper 11. Once the weight of the pet food in weighing hopper 11 reaches a preset value, the filling of weighing hopper 11 stops. The feed pipe 16 is equipped with a limiting plate 27, which blocks the feed pipe 16 to facilitate the pet food falling into the weighing hopper 11 for subsequent weighing. When the weight of the pet food in the weighing hopper 11 reaches the preset weight, the first reduction motor 20 drives the drive gear 19 to rotate, the drive gear 19 drives the driven gear 17 to rotate, the driven gear 17 drives the rotating rod 15 to rotate, and the rotating rod 15 drives the limiting plate 27 to rotate, thereby opening the port of the feed pipe 16 so that the pet food can enter the conveying trough 5 through the feed trough 32.

[0035] The conveying trough 5 is equipped with a second conveying assembly, which includes a transmission rod 29 rotatably mounted within the conveying trough 5. A second spiral blade 28 is fixedly sleeved on the side wall of the transmission rod 29. A mounting box 10 is fixedly mounted on the side of the base 1 away from the transmission rod 29. A third geared motor 31 is fixedly mounted inside the mounting box 10. A baffle 4 is hinged to the side of the base 1 away from the mounting box 10. The transmission rod 29 rotatably passes through the base 1 and extends into the mounting box 10 on the side away from the baffle 4. One end of the transmission rod 29 passing through the mounting box 10 is fixedly connected to the end of the output shaft of the third geared motor 31. When the weighed pet food falls into the conveying trough 5, it is conveyed by... The third geared motor 31 drives the transmission rod 29 to rotate, and the transmission rod 29 drives the second spiral blade 28 to rotate. Under the driving force of the second spiral blade 28, the pet food is discharged through the conveying trough 5 and falls into the placement bowl 6, which can serve as feeding. A baffle 4 is hinged at the port of the conveying trough 5, which serves to block the port of the conveying trough 5. When feeding is needed, the second spiral blade 28 drives the pet food to move, and the baffle 4 can be opened by the push of the pet food to facilitate the pet food falling. The second spiral blade 28 is made of rubber, which helps to reduce the damage to the pet food when the second spiral blade 28 rotates.

[0036] A placement groove 7 is provided on one side of the base 1, located below the conveying groove 5. A placement basin 6 is placed inside the placement groove 7. An inclined block is provided on the inner wall of the placement basin 6. Multiple positioning rods 30 arranged in an arc array are fixedly installed on the side wall of the placement basin 6. A positioning groove matching the positioning rods 30 is provided on the inner wall of the placement groove 7. A rubber sleeve is fixedly fitted on the side wall of the positioning rods 30. The placement basin 6 is placed in the placement groove 7, thus fulfilling the function of the placement basin 6. The positioning rods 30 on the side wall of the placement basin 6 engage with the positioning grooves on the inner wall of the placement groove 7 to further position the placement basin 6. The rubber sleeve on the side wall of the positioning rods 30 helps to increase the friction between the positioning rods 30 and the positioning grooves, thereby helping to maintain the stability of the placement basin 6. Through the cooperation of the positioning rods 30 and the positioning grooves, the placement basin 6 and the base 1 are set separately, making it easy for users to disassemble the placement basin 6 for cleaning.

[0037] The implementation principle of this utility model embodiment is as follows: When the device is in use, the bottom of the base 1 is equipped with a suction cup. The user places the device in a suitable position, and the suction cup adheres to the ground, which helps to maintain the stability of the device. The operator places the can 3 inside the shell 2 and assembles the can 3 and the shell 2 by using the plug-in assembly. The user lifts the cover plate on the top of the can 3 and pours the pet food into the can 3. After the pet food is placed, the user places the cover plate on top of the can 3. The bottom of the cover plate is equipped with a sealing gasket. The user places the sealing gasket inside the can 3. The friction generated between the sealing gasket and the inner wall of the can 3 can fix the cover plate.

[0038] After the pet food is added, the control panel on the side wall of the shell 2 sets the feeding time and quantity. When a small amount of food is needed, the first conveying component transports the pet food from inside the tank 3 to the weighing hopper 11. The weighing hopper 11 is equipped with a sealing component to prevent the pet food from falling. The weighing hopper 11 moves downward under the weight of the pet food, pushing the feeding pipe 16 to slide within the feeding trough 32. The cooperation between the feeding trough 32 and the feeding pipe 16 helps maintain the stability of the weighing hopper 11 during its lifting and lowering. When it descends, it comes into contact with the weighing component, which determines the weight of the pet food in the weighing hopper 11, facilitating accurate and quantitative feeding later. Once the weight of the pet food is determined, the first conveying component can be activated. The sealing component opens the discharge pipe 16 port, allowing the pet food to enter the conveying trough 5 through the feeding trough 32. Then, the second conveying component discharges the pet food from the conveying trough 5 port, and the pet food falls into the placement basin 6, thus achieving the feeding function. Through the cooperation of multiple transmission mechanisms, the function of autonomous feeding is achieved.

[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
