Description

Technical Field

[0001] This utility model relates to the field of pet feeder technology, and in particular to a pet feeder. Background Technology

[0002] With the improvement of living standards, more and more families are keeping pets. However, modern people lead very fast-paced lives, and many people cannot feed their pets on time when they are at work or out. They usually put food in a bowl before leaving home and let their pets eat on their own, but this may lead to irregular eating habits, causing indigestion and bringing unnecessary burdens to the owners. The emergence of pet feeders allows people to remotely control smart feeders to pour out food for their pets when they are not at home.

[0003] Pet feeders typically feature a separate food storage space with a food outlet. This storage space has a food outlet that connects to or closes with the food dispensing channel. To control the amount of food dispensed, the size of the food outlet is not very large. Chinese patent CN222263973U discloses a pet feeder with a stirrer at the food outlet to prevent blockage and ensure even food dispensing. However, this feeder requires three separate drive units to control the rotation or movement of each component, making the drive structure and dispensing operation quite complex. Utility Model Content

[0004] The present invention provides a pet feeder to solve the technical problem that the drive structure and food dispensing control process of existing smart pet feeders are relatively complex.

[0005] This utility model discloses a pet feeder, comprising:

[0006] A grain storage bin has a grain storage chamber and a grain outlet communicating with the grain storage chamber. The grain storage chamber is provided with a rotatable agitator at the grain outlet position, and the shaft of the agitator extends out of the grain storage bin.

[0007] The food dispensing unit includes a mounting shell, a movable platform, and a food dispensing channel disposed on the mounting shell. The mounting shell is installed below the food storage bin, the movable platform is slidably mounted on the mounting shell, and the food dispensing channel is fixed to the mounting shell and located on one side of the movable platform along its sliding direction. The movable platform has a food distribution compartment with openings at both the top and bottom. The movable platform moves relative to the mounting shell, causing the food distribution compartment to move and switch between a first position and a second position. In the first position, the first opening of the food distribution compartment is connected to the food dispensing outlet, and the second opening of the food distribution compartment is blocked, allowing the food distribution compartment to receive and store pet food. In the second position, the first opening of the food distribution compartment is misaligned with the food dispensing outlet, the movable platform blocks the food dispensing outlet, and the second opening of the food distribution compartment is connected to the inlet of the food dispensing channel, allowing the pet food in the food distribution compartment to be discharged through the food dispensing channel.

[0008] A drive assembly, housed within the mounting housing, includes a motor, a screw, a gear, and an acceleration gear set. The motor is fixed to the mounting housing. The screw is connected to the motor and threaded through the movable platform, with its axial direction parallel to the sliding direction of the movable platform. The gear is fixed to the movable platform and extends along the axial direction of the screw. The acceleration gear set is rotatably mounted on the mounting housing and meshes with the gear. The agitator's shaft is connected to the acceleration gear set. The motor drives the movable platform and the gear to move synchronously via the screw, and the movable platform drives the agitator to rotate synchronously via the meshing of the gear and the acceleration gear set.

[0009] In one embodiment, the mounting housing and the movable stage are assembled by a sliding connection structure. The sliding connection structure includes a guide groove and a guide protrusion that cooperates with the guide groove. One of the guide groove and the guide protrusion is located on the inner side wall of the mounting housing, and the other is located on the outer side wall of the movable stage. The extension squares of the guide groove and the guide protrusion are both parallel to the axial direction of the screw.

[0010] In one embodiment, the number of sliding connection structures is at least two, and the two sliding connection structures are simultaneously disposed on opposite sides of the moving platform and opposite sides of the screw.

[0011] In one embodiment, the grain outlet is connected to a grain outlet hose, which passes through the mounting housing. In the first position, the end of the grain outlet hose away from the grain outlet is aligned with the first opening of the grain distribution bin. In the second position, the end of the grain outlet hose away from the grain outlet is misaligned with the first opening of the grain distribution bin and abuts against the upper surface of the moving platform.

[0012] In one embodiment, the pet feeder is equipped with a vacuum pump, the suction end of which is connected to the food storage chamber, and the exhaust end of which is connected to the atmosphere; in the second position, the food dispensing hose elastically abuts against the upper surface of the moving platform, and the vacuum pump can draw away the air in the food storage chamber to form a vacuum food storage environment.

[0013] In one embodiment, the grain discharging body further includes a baffle and a support platform. The baffle is rotatably connected to the movable platform on the second opening side of the grain distribution bin. The support platform is fixed to the mounting housing and located below the movable platform. The upper surface of the support platform is flush with the inlet of the grain discharging channel, and the upper surface of the support platform is in contact with the inner wall of the grain discharging channel.

[0014] In the first position of the grain distribution bin, the baffle abuts against the support platform to cover the second opening of the grain distribution bin; as the baffle moves toward the grain outlet channel with the moving platform until the moment the baffle detaches from the support platform, the baffle swings down relative to the moving platform under the action of gravity to abut against the inner wall of the grain outlet channel, so that the second opening of the grain distribution bin is opened and the second opening is connected to the entrance of the grain outlet channel, and the grain distribution bin is switched to the second position.

[0015] In one embodiment, the bottom wall of the grain storage chamber is provided with a stirring groove, and the agitator includes multiple circumferentially spaced stirring blades, the length of which is smaller than the radial dimension of the stirring groove; the grain outlet is located on the bottom wall of the stirring groove, and during the rotation of the agitator, the stirring blades intermittently pass above the grain outlet.

[0016] In one embodiment, the pet feeder further includes a feeding tray that is detachably fitted to the mounting housing and located below the outlet of the food dispensing channel.

[0017] In one embodiment, the accelerating gear set includes a first spur gear and a second spur gear meshing together, the axis of the first spur gear being parallel to the axis of the second spur gear; the first spur gear meshes with a strip tooth, and the rotating shaft of the stirrer is fixedly connected to the second spur gear and rotates synchronously with the second spur gear; wherein the number of teeth of the first spur gear is greater than the number of teeth of the second spur gear.

[0018] In one embodiment, the pet feeder is equipped with a camera sensing module, which includes a camera and a control chip electrically connected. The camera is embedded in the outer wall of the mounting housing near the outlet side of the food dispensing channel, and the motor is electrically connected to the control chip.

[0019] When the camera detects that the straight-line distance between the pet and the food dispensing unit is within the target range, the control chip controls the start of the motor to drive the food dispensing unit to feed the pet.

[0020] When the camera detects that the straight-line distance between the pet and the food dispensing unit is outside the target range, the control chip controls the motor to disconnect, thereby preventing the food dispensing unit from dispensing food.

[0021] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0022] This utility model provides a pet feeder. The food storage container has a stirrer at its outlet. The main body of the feeder includes a moving platform and a feed channel. The moving platform has a food distribution compartment with openings at both ends. The food distribution compartment moves synchronously with the moving platform, switching between a first position and a second position. In the first position, the food distribution compartment is connected to the food outlet; in the second position, it is connected to the feed channel, allowing the food flowing from the outlet to be discharged to the outside via the food distribution compartment and the feed channel for the pet to eat. Furthermore, the drive assembly uses a single motor to simultaneously drive the movement of the moving platform and the rotation of the stirrer, achieving both food discharge and mixing functions. Compared to Chinese Patent CN222263973U, which uses multiple drive components (i.e., multiple motors) to provide driving force, the pet feeder of this application is more convenient to operate, and the drive assembly and installation are more convenient and compact, greatly improving the overall intelligence of the pet feeder.

[0041] Reference Figure 1 and Figure 2 This application provides a pet feeder 1, including a food storage bin 10, a food dispensing body 20, and a drive assembly 30. The food storage bin 10 is used to store and hold pet food, and a single addition of food can feed the pet multiple times. The food dispensing body 20 is located below the food storage bin 10 and is used to discharge the food from the food storage bin 10 to the outside for the pet to eat. The drive assembly 30 is located inside the food dispensing body 20 and is used to drive and control the food storage bin 10 and the food dispensing body 20 to achieve automatic and quantitative food dispensing. The pet feeder 1 of this application can provide intelligent and regular feeding for pets. Even when the owner is not at home, the pet can be remotely controlled to intelligently feed the pet, ensuring the pet's healthy eating.

[0042] Reference Figures 1-3 The grain storage hopper 10 has a grain storage chamber 11 and a grain outlet 111 communicating with the grain storage chamber 11. A rotatable stirrer 12 is provided at the grain outlet 111 of the grain storage chamber 11. The rotating shaft 121 of the stirrer 12 extends out of the grain storage hopper 10 and connects to the drive assembly 30. Here, to control the grain outflow, the size of the grain outlet 111 of the grain storage chamber 11 is not very large. The stirrer 12 is placed at the grain outlet 111 to prevent grain blockage, thereby achieving uniform grain dispensing. The grain dispensing body 20 includes a mounting housing 21, a movable platform 22 disposed within the mounting housing 21, and a grain dispensing channel 23. The mounting housing 21 is installed below the grain storage hopper 10, the movable platform 22 is slidably mounted on the mounting housing 21, and the grain dispensing channel 23 is fixed to the mounting housing 21 and located on one side of the movable platform 22 along its sliding direction. The movable platform 22 is equipped with a grain distribution bin 24 with openings at both the top and bottom. The movable platform 22 moves relative to the mounting housing 21, allowing the grain distribution bin 24 to switch between a first position and a second position. Specifically, Figure 2The diagram shows that in the first position, the first opening 241 of the grain distribution bin 24 is connected to the grain outlet 111, the grain distribution bin 24 is connected to the grain storage chamber 11, the second opening 242 of the grain distribution bin 24 is blocked, and the grain in the grain storage chamber 11 flows into the grain distribution bin 24 through the grain outlet 111. Figure 3 The diagram shows that in the second position, the first opening 241 of the food distribution bin 24 is misaligned with the food outlet 111, the moving platform 22 blocks the food outlet 23, and the food distribution bin 24 is separated from the food storage chamber 11; the second opening 242 of the food distribution bin 24 is connected to the inlet 231 of the food outlet channel 23, and the food distribution bin 24 is connected to the food outlet channel 23, so that the pet food in the food distribution bin 24 is discharged to the outside through the food outlet channel 23 for the pet to eat.

[0043] Reference Figures 2-4 The drive assembly 30 is housed within the mounting housing 21 and includes a motor 31, a screw 32, a gear 33, and an acceleration gear set 34. The motor 31 is fixed to the mounting housing 21. The screw 32 is connected to the motor 31 and threaded through the moving platform 22. The axial direction of the screw 32 is parallel to the sliding direction of the moving platform 22. The gear 33 is fixed to the moving platform 22 and extends along the axial direction of the screw 32. The acceleration gear set 34 is rotatably mounted on the mounting housing 21 and meshes with the gear 33. The rotating shaft 121 of the stirrer 12 is connected to the acceleration gear set 34. The motor 31 drives the moving platform 22 and the gear 33 to move synchronously through the screw 32. The moving platform 22 drives the stirrer 12 to rotate synchronously through the meshing of the gear 33 and the acceleration gear set 34, so that one motor 31 can simultaneously drive the moving platform 22 to move and the stirrer 12 to rotate.

[0044] This application provides a pet feeder 1. The food storage bin 10 has a food outlet 111 equipped with a stirrer 12. The main body 20 has a moving platform 22 and a food outlet channel 23. The moving platform 22 has a food distribution compartment 24 with openings at both ends. The food distribution compartment 24 moves synchronously with the moving platform 22, switching between a first position and a second position. In the first position, the food distribution compartment 24 is connected to the food outlet 111; in the second position, the food distribution compartment 24 is connected to the food outlet channel 23, allowing the food flowing from the food outlet 111 to be discharged to the outside via the food distribution compartment 24 and the food outlet channel 23 for the pet to eat. Furthermore, the drive assembly 30, through a motor 31, can simultaneously drive the movement of the moving platform 22 and the rotation of the stirrer 12, simultaneously realizing the functions of food discharge and food mixing. Compared to the Chinese patent CN222263973U, which uses multiple drive components, i.e., multiple motors, to provide driving force, the pet feeder 1 of this application is easier to operate, and the drive component 30 and its installation are more convenient and compact, greatly improving the intelligence of the entire pet feeder 1.

[0045] Optionally, in conjunction with reference Figure 4 and Figure 5In one embodiment, the mounting housing 21 and the moving stage 22 are assembled together via a sliding connection structure 25. The sliding connection structure 25 includes a guide groove 251 and a guide protrusion 252 that mates with the guide groove 251. Since they are in a mating assembly relationship, one of the guide groove 251 and the guide protrusion 252 is located on the inner sidewall of the mounting housing 21, and the other is located on the outer sidewall of the moving stage 22. The extending directions of both the guide groove 251 and the guide protrusion 252 are parallel to the axial direction of the screw 32. The motor 31 drives the screw 32 to rotate, and the moving stage 22 moves synchronously relative to the mounting housing 21 via the sliding connection structure 25. Here, the sliding connection structure 25 can further improve the assembly stability between the mounting housing 21 and the moving stage, and limit the offset of the moving stage 22 in the non-sliding direction during sliding; the sliding connection structure 25 provides support and limiting functions for the moving stage. Of course, in other embodiments, the sliding connection structure 25 is not required. Since the motor 31 and the screw 32 are fixed to the mounting housing, and the movable stage 22 is threaded through the screw 32, the mounting housing 21 and the movable stage 22 can be directly connected via the motor 31 and the screw 32. Alternatively, the sliding connection structure 25 can also be a sliding groove and a sliding rod that fit together. Having a sliding groove on one of the mounting housing 21 and the movable stage 22, and a sliding rod on the other, can also achieve the support and limiting function. Therefore, in this application, the presence or absence of the sliding connection structure 25 and its structural method are not limited.

[0046] Preferably, in conjunction with reference Figure 4 and Figure 5In one embodiment, there are multiple sliding connection structures 25, with at least two sliding connection structures 25 simultaneously located on opposite sides of the moving platform 22 and opposite sides of the screw 32, defined as two first sliding connection structures 25a. The two guide grooves 251 and two guide protrusions 252 corresponding to the two first sliding connection structures 25a are respectively located on the inner sidewall of the mounting housing 21 and on opposite sides of the screw 32, and the other is located on opposite sides of the outer sidewall of the moving platform 22 to slide in contact with the two guide grooves 251. The remaining sliding connection structures 25 are defined as second sliding connection structures 25b, with one guide groove 251 and guide protrusion 252 corresponding to the second sliding connection structure 25b located on the inner sidewall of the mounting housing 21 and the other on the outer sidewall of the moving platform 22. Here, the arrangement of multiple sliding connection structures 25 greatly improves the assembly stability of the moving stage 22. In particular, the design of the two first sliding connection structures 25a not only achieves double-sided limiting of the moving stage 22, but also, because the two first sliding connection structures 25a are simultaneously located on opposite sides of the screw 32, to a certain extent, restricts the rotational offset of the moving stage 22 relative to the screw 32. The arrangement of the second sliding connection structure 25b further improves the assembly stability of the moving stage 22. Therefore, in this application, in other embodiments, the number of sliding connection structures 25 is not limited, the arrangement of the first sliding connection structure 25a or the second sliding connection structure 25b is not limited, and the positions of the guide groove 251 and the guide protrusion 252 are not limited; they can simply cooperate with each other for sliding assembly.

[0047] Preferably, in conjunction with reference Figures 2-4 In one embodiment, the grain outlet 111 is connected to a grain outlet hose 13, which passes through the mounting housing 21. When the grain distribution bin 24 is in the first position, the end of the grain outlet hose 13 away from the grain outlet 111 is aligned with the first opening 241 of the grain distribution bin 24. When the grain distribution bin 24 is in the second position, the end of the grain outlet hose 13 away from the grain outlet 111 is misaligned with the first opening 241 of the grain distribution bin 24 and abuts against the upper surface of the moving platform 22 to block the grain outlet 111. The grain outlet hose 13 serves to guide the grain at the grain outlet 111 and prevents the grain from splashing along the side of the grain outlet 111. In other embodiments, the grain at the location of the grain outlet 111 can also be guided out by a guide rail or a chute. In another embodiment, the grain outlet hose 13 is not provided; as long as the grain outlet 111 can be aligned and connected with the first opening 241 of the grain distribution bin 24 in the first position, the grain can still be discharged.

[0048] Preferably, refer to Figure 3In one embodiment, the pet feeder 1 is equipped with a vacuum pump 40. The suction end 41 of the vacuum pump 40 is connected to the food storage chamber 11, and the exhaust end 42 of the vacuum pump 40 is connected to the atmosphere. When the food compartment 24 is in the second position, the food dispensing hose 13 elastically abuts against the upper surface of the moving platform 22 to seal the food outlet 111. At this time, the vacuum pump 40 can remove the air from the food storage chamber 11 to form a vacuum food storage environment. Here, the food dispensing hose 13 can not only dispense food but also seal the food outlet 111, facilitating the vacuum pump 40 to evacuate the food storage chamber 11. The location of the vacuum pump 40 is not limited; it can be installed inside the mounting housing 21 or outside the food storage container 10. The vacuum pump 40 is generally connected to the food storage chamber 11 using a vacuum hose or a metal air pipe. It should be understood that vacuum food storage can extend the shelf life of the food in the food storage container 10, prevent moisture and water damage, prevent food spoilage, and ensure the health and hygiene of the pet's food. Of course, in other embodiments, the vacuum pump 40 may not be required, and pet food may not necessarily be vacuum stored.

[0049] Preferably, in conjunction with reference Figure 2 , Figure 3 and Figure 5In one embodiment, the grain discharging body 20 further includes a baffle 26 and a support platform 27. The baffle 26 is rotatably connected to the movable platform 22 on one side of the second opening 242 of the grain distribution bin 24. The support platform 27 is fixed to the mounting housing 21 and located below the movable platform 22. The upper surface of the support platform 27 is flush with the inlet 231 of the grain discharging channel 23 and is in contact with the inner wall of the grain discharging channel 23. In the first position of the grain distribution bin 24, the baffle 26 abuts against the support platform 27 to cover the second opening 242 of the grain distribution bin 24. At this time, the first opening 241 of the grain distribution bin 24 is aligned and connected with the grain outlet 111, and the second opening 242 is blocked by the baffle 26. The grain distribution bin 24 can receive the grain flowing out of the grain storage chamber 11. As the moving platform 22 moves toward the food dispensing channel 23, the baffle 26, under the influence of gravity, swings down relative to the moving platform 22 to the inner wall of the inlet 231 of the food dispensing channel 23. This opens the second opening 242 of the food distribution bin 24, connecting it to the inlet 231 of the food dispensing channel 23. The food distribution bin 24 then switches to its second position, and the food inside is discharged through the food dispensing channel 23 to the outside for the pets to eat. Conversely, when the moving platform 22 moves away from the food dispensing channel 23, the baffle 26 is lifted by the support platform 27 and swings down relative to the moving platform to cover the second opening 242 of the food distribution bin 24. The additional baffle 26 further enhances the sealing performance when the second opening 242 is blocked. Furthermore, as long as a portion of the baffle 26 is in contact with the support platform 27, it can also block the second opening 242 of the food distribution bin 24. Therefore, food can only be discharged from the food distribution channel 23 when the second opening 242 of the food distribution bin 24 is fully connected to the inlet 231 of the food discharge channel 23. This better controls the frequency and weight of pet food discharge, achieving quantitative dispensing and a fixed amount of food discharged from the food distribution bin 24 at a time. Moreover, the baffle 26 provides a reminder function by blocking and releasing the food. Of course, in other embodiments, the baffle 26 is not required; it is sufficient that the upper surface of the support platform 27 can block the second opening 242 of the food distribution bin 24 in the first position.

[0050] Preferably, combined with Figure 2 and Figure 6In one embodiment, the bottom wall of the grain storage chamber 11 is provided with a stirring groove 112, and the agitator 12 includes multiple circumferentially spaced stirring blades 122, the length of which is smaller than the radial dimension of the stirring groove 112. The grain outlet 111 is located on the bottom wall of the stirring groove 112. During rotation, the stirring blades 122 intermittently pass above the grain outlet 111, stirring the grain near the outlet to prevent blockage and ensure proper grain dispensing. Here, the stirring groove 112 functions as a grain divider. Without it, the agitator 12 would need to stir the grain throughout the entire grain storage chamber 11, which would not only easily crush the grain but also require greater stirring power. Of course, without considering the stirring power, in other embodiments, the stirring groove 112 may be omitted, and the number of stirring blades 122 is not limited.

[0051] Optionally, in conjunction with reference Figure 5 and Figure 6 In one embodiment, the acceleration gear set 34 includes a meshing first spur gear 341 and a second spur gear 342, with the axes of the first spur gear 341 and the second spur gear 342 parallel to each other. The first spur gear 341 meshes with a strip tooth 33, and the rotating shaft 121 of the stirrer 12 is fixedly connected to the second spur gear 342 and rotates synchronously with the second spur gear 342. The first spur gear 341 has a greater number of teeth than the second spur gear 342, and the rotational speed of the second spur gear 342 is greater than the rotational speed of the first spur gear 341, thereby achieving an acceleration function and providing rotational power to the stirrer 12. It should be noted that in other embodiments, the number of gears included in the acceleration gear set 34 is not limited; any gear combination that can achieve the speed-up function should be included.

[0052] Optionally, in conjunction with reference Figure 1 and Figure 2 In one embodiment, the pet feeder 1 further includes a feeding tray 50, which is detachably mounted to the mounting housing 21 and located below the outlet 232 of the food dispensing channel 23 to receive food for the pet. Of course, in other embodiments, the pet feeder 1 does not require a feeding tray 50; the user can directly use a regular bowl or container instead of the feeding tray 50, placing it below the outlet 232 of the food dispensing channel 23.

[0053] Preferably, in conjunction with reference Figure 1 and Figure 2In one embodiment, the pet feeder 1 is equipped with a camera sensing module 60, which includes a camera 61 electrically connected to a control chip (not shown). The camera 61 is embedded in the outer wall of the mounting housing 21 near the outlet 232 of the food dispensing channel 23. The motor 31 is electrically connected to the control chip. When the camera 61 detects that the straight-line distance of the pet fish food dispensing body 20 is within the target range, the control chip controls the start of the motor 31 to drive the food dispensing body 20 to dispense food to feed the pet. When the camera 61 detects that the straight-line distance of the pet fish food dispensing body 20 is outside the target range, the control chip controls the disconnection of the motor 31 to stop the food dispensing body 20 from dispensing food. The camera sensing module 60 further enhances the intelligence of the pet feeder 1, eliminating the need for manual control of food dispensing or stopping. Furthermore, the camera sensing module 60 can record the number of times the pet eats, facilitating health monitoring for the pet owner. Of course, in other embodiments of this application, the inclusion or absence of the camera sensing module 60 is not limited.
