Description

Technical Field

[0001] This application belongs to the field of pet feeding equipment technology, and more specifically, relates to a pet feeder. Background Technology

[0002] Pet feeding typically involves placing food or cereal in a feeding seat for the pet to eat. However, it's difficult to accurately predict a pet's appetite, and pets rarely finish all the food or cereal, inevitably leaving food residue in the feeding seat. Food can also become damp and spoil when exposed to air, and this spoiled food or cereal is highly likely to be ingested by the pet during the next feeding, potentially affecting its health. Furthermore, existing pet feeders cannot weigh the pet while feeding. Utility Model Content

[0003] The purpose of this application is to provide a pet feeder to solve the technical problems of residue in the feeding trough and the inability to weigh the pet when feeding it, which exist in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application embodiment is to provide a pet feeder, which includes at least a first compartment and a second compartment arranged sequentially from bottom to top in the height direction, wherein:

[0005] The first compartment can be detachably installed at the bottom of the second compartment;

[0006] A feeding seat is floatingly connected to the second chamber. A pressure sensor is connected between the feeding seat and the second chamber. The bottom of the feeding seat has a channel that can communicate with the first chamber. The bottom plate of the feeding seat is movable. A power supply, a control module, and a drive assembly are electrically connected to each other in the second chamber. The pressure sensor is electrically connected to the control module. The drive assembly is used to drive the bottom plate to extend or retract to close or open the channel. When the bottom plate moves, the side wall of the feeding seat can abut against the upper surface of the bottom plate to sweep feed residue on the bottom plate into the first chamber.

[0008] Optionally, a chute is provided on the feeding seat, the opening of the chute facing the first chamber, and the base plate is mounted and slidably disposed in the chute.

[0009] Optionally, the drive assembly includes a motor and a lead screw and nut mechanism connected to the output shaft of the motor. The nut in the lead screw and nut mechanism is connected to a push block, which is connected to the base plate to drive the base plate to reciprocate along a straight line.

[0010] Optionally, two abutment blocks are spaced apart on the base plate along its moving direction, the interval between the two abutment blocks being greater than the thickness of the push block, and the push block being located between the two abutment blocks; the push block abuts against different abutment blocks to push or pull the base plate to move.

[0011] Optionally, a first magnetic attractant is provided on the base plate, and a second magnetic attractant is provided in the feeding seat; when the base plate completely closes the channel, the first magnetic attractant and the second magnetic attractant are attracted to each other.

[0012] Optionally, the feeding seat includes a first seat and a second seat, the channel and the chute are both formed in the first seat, the second seat is detachably disposed in the first seat along the sliding direction of the base plate, the pressure sensor is connected to the second chamber and the first seat, and the base plate is slidably disposed between the first seat and the second seat.

Two elastic locking arms are provided on the side of the slider facing the second seat. The opening of the slide rail is smaller than the width of the two locking arms when they are open. The locking block abuts against the slider. In a first position, the elastic locking arms are fully open to release the locking block. In a second position, the elastic locking arms are squeezed by the opening of the slide rail to retract and hold the locking block.

[0015] Optionally, a spring is connected between the bottom of the slide and the slider; a closed-loop positioning groove with multiple bends is provided on the side wall of the slide, and a positioning post that can cooperate with the positioning groove is rotatably provided on the slider; the compression of the spring in the first position is less than the compression in the second position.

[0016] The pet feeder provided in this application embodiment has at least the following beneficial effects:

[0017] By making the base plate of the feeding seat movable, when the channel is opened, the side wall of the feeding seat can sweep any remaining grain feed on the base plate into the channel and collect it in the first compartment, thereby avoiding grain feed residue in the feeding seat and ensuring the pet's eating safety. At the same time, the first compartment is detachable, so it can be easily removed for cleaning. In addition, a pressure sensor is connected between the feeding seat and the second compartment. When the pet stands on the feeding seat to eat, the control module can obtain the data from the pressure sensor to weigh the pet at the same time as feeding. Attached Figure Description

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0030] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0031] Please refer to the following: Figures 1 to 7 The pet feeder provided in the embodiments of this application will now be described.

[0032] It is understood that, in the specific application of the pet feeder described in this application, the pet can be a pet bird.

[0033] refer to Figures 1 to 4 It is understood that the pet feeder described in this application embodiment includes a first compartment 10 and a second compartment 20 arranged sequentially from bottom to top in the height direction, wherein the first compartment 10 is detachably disposed at the bottom of the second compartment 20.

[0034] Specifically, a feeding seat 30 is floatingly connected to the second compartment 20, and the feeding seat 30 is used for the pet to stand on to eat. A pressure sensor 80 is connected between the feeding seat 30 and the second compartment 20, and the pressure sensor 80 is used to detect the weight change of the feeding seat 30. The bottom of the feeding seat 30 is provided with a channel A that can communicate with the first compartment 10. The base plate 40 in the feeding seat 30 is movably set. A power supply, control module and drive assembly 50 are provided in the second compartment 20, which are electrically connected to each other. The pressure sensor 80 is electrically connected to the control module. The drive assembly 50 is used to drive the base plate 40 to extend or retract to close or open the channel A. When the base plate 40 moves, the side wall of the feeding seat 30 can abut against the upper surface of the base plate 40 to sweep the food residue on the base plate 40 into the first compartment 10.

[0035] Understandably, the aforementioned control module is used to control the start and stop of the drive component 50 and to acquire the detection data of the pressure sensor 80.

[0036] In some implementations, the base plate 40 is driven by the drive assembly 50 to move in a straight line, thereby opening or closing the channel A.

[0037] refer to Figures 2 to 5 In other embodiments, the base plate 40 is driven to rotate by the drive assembly 50, that is, the base plate 40 is fan-shaped, and the drive assembly 50 may be a rotary motor to drive the base plate 40 to rotate to open or close the channel A.

[0038] By movably setting the base plate 40 of the feeding seat 30, when the channel A is opened, the side wall of the feeding seat 30 can sweep the residual grain feed on the base plate 40 into the channel A and collect it in the first compartment 10, thereby avoiding grain feed residue in the feeding seat 30 and ensuring the pet's eating safety; in addition, the first compartment 10 is detachable, so that it can be easily removed for cleaning to prevent residual feed residue from becoming moldy.

[0039] refer to Figures 2 to 4 In some embodiments, the pressure sensor 80 can be connected in the following way: A connecting structure 35 is provided through the channel A on the feeding seat 30, along the center line of channel A, and the connecting structure 35 is connected to the pressure sensor 80. It should be understood that the base plate 40 is slidably disposed above the connecting structure 35. That is, when the base plate 40 closes the channel A, the bottom of the feeding seat 30 is still a flat base plate 40 to facilitate food storage and pet feeding; when the base plate 40 opens the channel A, the connecting structure 35 is formed in the center of the channel A at the bottom of the feeding seat 30.

[0040] Specifically, one end of the connecting structure 35 away from the drive assembly 50 is connected to the pressure sensor 80 by screws; the other end of the pressure sensor 80 is connected to the second chamber 20 by screws. The connecting structure 35 is positioned along the centerline of channel A, ensuring a more balanced weight distribution on both sides of the pressure sensor 80 from the feeding seat 30, effectively preventing inaccurate detection due to uneven force on the pressure sensor 80. Furthermore, the upper surface of the connecting structure 35 is symmetrically inclined on both sides, allowing feed residue to slide down the inclined upper surface into the first chamber 10.

[0041] In other embodiments, the pressure sensor 80 may also be directly connected to the second chamber 20 and the side of the feeding seat 30 near the second chamber 20. That is, unlike the above embodiments, the pressure sensor 80 is not located in the channel A.

[0042] refer to Figure 5Furthermore, a chute 34 is provided in the feeding seat 30, with the opening of the chute 34 facing both the drive assembly 50 and the first chamber 10. The base plate 40 is mounted and slidably disposed in the chute 34. By providing the chute 34, the movement of the base plate 40 can be made more stable when sliding to close or open the channel A.

[0043] refer to Figures 2 to 5 In some embodiments, the base plate 40 moves in a straight line. Specifically, the drive assembly 50 includes a motor 51 and a linear motion assembly driven by the motor 51. The linear motion assembly is connected to the base plate 40 to drive the base plate 40 to reciprocate in a straight line. Specifically, the linear motion assembly includes a lead screw and nut mechanism connected to the output shaft of the motor 51. The nut in the lead screw and nut mechanism is connected to a push block 53, and the push block 53 is connected to the base plate 40.

[0044] refer to Figure 3 and Figure 5 Furthermore, two abutment blocks 41 are spaced apart on the base plate 40 along its direction of movement, and a push block 53 is located between the two abutment blocks 41; the push block 53 abuts against different abutment blocks 41 to push or pull the base plate 40 to move. Specifically, when closing channel A, the nut drives the push block 53 to push the previous abutment block 41; when opening channel A, the nut drives the push block 53 to pull the next abutment block 41; it can be understood that the "previous abutment block 41" refers to the abutment block 41 closer to the feeding seat 30, and the "next abutment block 41" refers to the abutment block 41 farther away from the feeding seat 30.

[0045] Understandably, the distance between the two abutment blocks 41 is slightly greater than the thickness of the push block 53. Thus, the push block 53 only needs to be engaged between the two abutment blocks 41 to complete the assembly.

[0046] refer to Figure 5 Furthermore, a micro switch 21 is provided in the second chamber 20, located on one side of the lead screw and nut mechanism. The micro switch 21 is electrically connected to the control module. For example, two micro switches 21 are provided at both ends of the travel stroke of the push block 53. When the push block 53 moves in a straight line and touches the micro switch 21 at the end of its travel stroke, the micro switch 21 sends a switching signal to the control module to stop the motor 51 from driving the lead screw 52 to rotate, or to control the motor 51 to drive the lead screw 52 to rotate in the opposite direction.

[0047] refer to Figure 3Furthermore, a first magnetic attractor 42 is provided on the base plate 40, and a second magnetic attractor (not shown in the figure) is provided in the feeding seat 30; when the base plate 40 completely closes the channel A, the first magnetic attractor 42 and the second magnetic attractor are attracted to each other. It should be understood that the first magnetic attractor 42 is located on the base plate 40 near the abutment block 41 of the feeding seat 30 and is not located between the two abutment blocks 41. That is, when the first magnetic attractor 42 and the second magnetic attractor are attracted to each other, the base plate 40 moves forward a small distance under the action of magnetic force. At this time, the first abutment block 41 can disengage from the push block 53.

[0048] Since the base plate 40 is slidably mounted on the feeding seat 30, and the feeding seat 30 is connected to the pressure sensor 80, it is generally necessary to ensure that the object being tested is not connected to the outside world when the pressure sensor 80 is performing weight detection, in order to avoid problems such as detection data errors caused by the connection. As mentioned above, the movement of the base plate 40 is achieved by the push block 53 pushing or pulling the abutment block 41. By setting a first magnetic attractant 42 on the base plate 40 and a second magnetic attractant (not shown in the figure) in the feeding seat 30, when the first magnetic attractant 42 and the second magnetic attractant are attracted to each other, the magnetic force can pull the base plate 40 forward a small distance so that the abutment block 41 is disengaged from the push block 53, thereby avoiding external connection and affecting the detection accuracy of the pressure sensor 80.

[0049] In addition to the above functions, the first magnetic attraction 42 and the second magnetic attraction also enable the base plate 40 to maintain a stable closed state under magnetic force after the closed channel A is closed, so as to avoid the situation where the feeding seat 30 shakes when the pet enters or exits, which would prevent the base plate 40 from completely closing the channel A and causing the feed in the feeding seat 30 to enter the first compartment 10.

[0050] Understandably, the supply of feed or grain in the feeding station 30 can be either manual or automatic.

[0051] refer to Figures 2 to 4 For example, in the automatic grain feed supply system, a motor 73 is installed in the second compartment 20. The motor 73 is electrically connected to the aforementioned control module. A third compartment 70 is also installed at the top of the second compartment 20. The third compartment 70 contains a storage compartment 71, which is funnel-shaped. A stirring plate 72 is installed at the bottom of the funnel of the storage compartment 71. The rotating shaft of the motor 73 is connected to the stirring plate 72. A feeding channel B is provided between the storage compartment 71 and the second compartment 20. The stirring plate 72 is located at the entrance of the feeding channel B and has a fan-shaped feeding port. When the rotating shaft of the motor 73 drives the stirring plate 72 to rotate until its fan-shaped feeding port connects with the feeding channel B, the feeding channel B connects with the feeding seat 30 for automatic feeding of the feeding seat 30.

[0052] refer to Figures 2 to 5 and Figure 7 Based on the above embodiments, the feeding seat 30 includes a first seat 31 and a second seat 32. The first seat 31 is fixedly mounted on the second compartment 20, and the channel A and the slide 34 are both formed in the first seat 31. The second seat 32 is detachably mounted on the first seat 31, and the base plate 40 is slidably mounted between the first seat 31 and the second seat 32. Since pets generally stand on the second seat 32 to eat, this design allows for easy detachment of the second seat 32 for cleaning.

[0053] It is understandable that the aforementioned second magnetic attractor and slide 34 are both located on the first base 31.

[0054] It is understood that the aforementioned pressure sensor 80 is connected to the first base 31 and the second chamber 20. In some embodiments, the aforementioned connection structure 35 is disposed on the first base 31.

[0055] refer to Figure 6 and Figure 7 The second seat 32 is detachably mounted on the first seat 31 along the sliding direction of the base plate 40. A locking block 33 is provided on the axis of the second seat 32 along its sliding direction. An elastic locking arm 61 capable of holding or releasing the locking block 33 is provided on the first seat 31. When the elastic locking arm 61 holds the locking block 33, the second seat 32 is connected to the first seat 31 as one unit. When the elastic locking arm 61 releases the locking block 33, the second seat 32 can be removed from the first seat 31 for cleaning.

[0056] Specifically, a slide rail 62 is provided on the first seat 31, and a slider 63 is slidably disposed in the slide rail 62. Two elastic locking arms 61 are provided on the side of the slider 63 facing the second seat 32. The opening of the slide rail 62 is smaller than the width of the two locking arms when they are open. The locking block 33 can abut against the slider 63 to push the slider 63 to slide to different positions in the slide rail 62.

[0057] That is, the elastic locking arms 61 are always in an open tendency under the action of elastic force. When the slider 63 is at different depth positions in the slide rail 62, the two sides of the opening of the slide rail 62 can squeeze each elastic locking arm 61 to change the opening width between the two elastic locking arms 61, thereby realizing the clamping of the block by the elastic locking arms 61. Specifically, in the first position, the elastic locking arms 61 are fully open to release the block 33; in the second position, the elastic locking arms 61 are squeezed by the opening of the slide rail 62 to contract and hold the block 33. Further, a spring 64 is connected between the bottom of the slide rail 62 and the slider 63; a closed-loop positioning groove 65 with multiple bends is provided on the side wall of the slide rail 62. Specifically, the top of the positioning groove 65 is the aforementioned first position, the middle position of the positioning groove 65 is the second position, and the shape of the positioning groove 65 in the second position is bent, with the second position located at the top of the bend. Furthermore, a positioning post 66 is rotatably mounted on the slider 63, capable of engaging with the positioning groove 65. The positioning post 66 can slide within the positioning groove 65 to switch back and forth between a first position and a second position. Simultaneously, the spring 64 is configured such that its compression in the first position is less than its compression in the second position. Thus, under the elastic force of the spring 64, the positioning post 66 can be held against the top of the bend in the positioning groove 65 (i.e., held in the second position).

[0058] Specifically, when the second seat 32 is assembled onto the first seat 31, the locking block 33 on the second seat 32 collides with the slider 63 and pushes the slider 63 to slide to the second position in the slide rail 62, so that the elastic locking arm 61 can hold the locking block 33; when the second seat 32 needs to be removed from the first seat 31, the second seat 32 is pressed, so that the positioning post 66 is released in the positioning groove 65, so that the slider 63 moves from the second position to the first position under the action of springing away, thereby releasing the elastic locking arm 61, and the elastic locking arm 61 opens to release the locking block 33.

[0059] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
