Description

Technical Field

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

[0002] Most existing pet feeders only have one feeding bowl, which is only suitable for feeding a single pet. If used to feed multiple pets, they need to share a feeding bowl, which can easily lead to fighting over food, hindering harmonious coexistence and healthy feeding.

[0003] To address the aforementioned technical issues, Chinese utility model patent CN216567648U discloses a novel pet feeder, comprising a storage tank, a base, and a food trough. The storage tank is mounted on the base, and food troughs are installed on both sides of the base. A motor and a food dispensing channel are provided within the base, with the outlet of the food dispensing channel corresponding to the position of the food trough. A feeding port is provided at the bottom of the storage tank. A rotating seat is fixedly connected to the storage tank within the base, and the rotating seat has a food dispensing port that connects the feeding port and the food dispensing channel. A dispensing disc is provided within the rotating seat and rotates therewith. A rotating disk, fitted onto a transmission shaft, is located at the bottom of the rotating seat within the base and rotates therewith. The rotating disk has a baffle that covers the food dispensing channel by rotating its position. A gear shaft is integrally formed at the center bottom of the rotating disk, and an operating lever for driving the gear shaft to rotate is installed within the base. The aforementioned existing pet feeders require manual adjustment of the control lever to rotate the baffle to control the opening or closing of the food dispensing channel, which is inconvenient to operate; moreover, when there are two or more food dispensing channels, it is impossible to control only one of the dispensing channels to be open.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] The purpose of this utility model is to provide a pet feeder that addresses the shortcomings and deficiencies of the existing technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a pet feeder, including a food dispensing chamber, multiple food dispensing channels, and multiple food bowls. A food conveying component is rotatably disposed within the food dispensing chamber. Multiple food dispensing ports are circumferentially connected to the inlets of the multiple food dispensing channels, and the outlets of the multiple food dispensing channels correspond one-to-one with the multiple food bowls. The feeder also includes a rotating plate, a control mechanism, and a first position detection device. The rotating plate covers the bottom surface of the food dispensing chamber and has a food dispensing control port. The first position detection device detects the rotational position of the food dispensing control port. The control mechanism is electrically connected to both the first position detection device and a first drive mechanism. The first drive mechanism drives the rotating plate to rotate, allowing the food dispensing control port to selectively connect with any of the food dispensing ports.

[0007] Because the rotating vane covers the bottom surface of the food dispensing chamber, it blocks the food dispensing port that is not connected to the food dispensing control port. The food conveyor rotates within the food dispensing chamber, thus pushing the pet food in the chamber out of the food dispensing port connected to the food dispensing control port. When the first drive mechanism rotates the food dispensing control port above the designated food dispensing channel, the dispensing channel opens; the pet food in the dispensing chamber, under the pushing action of the food conveyor and its own gravity, passes sequentially through the food dispensing port, the food dispensing control port, and the food dispensing channel before falling into the corresponding food bowl.

[0008] By linking the first position detection device with the control mechanism, the rotation position of the feed control port is detected and controlled, thereby automatically and accurately opening the designated feed channel, which is easy to operate. When two or more feed channels are configured, the opening and closing of each feed channel can be controlled in an orderly manner, effectively improving the convenience and order of feeding multiple pets and enhancing the user experience.

[0009] According to the above scheme, the first position detection device includes a positioning plate fixed to the rotating plate and a photoelectric sensor. The positioning plate is provided with a plurality of positioning openings that correspond one-to-one with the grain outlet. When the grain outlet control port rotates to communicate with one of the grain outlets, the corresponding positioning opening rotates synchronously to the detection position of the photoelectric sensor.

[0010] When the grain discharge control port rotates to connect with one of the grain discharge ports, the positioning opening on the positioning plate that corresponds uniquely to that grain discharge port rotates synchronously to the detection position of the photoelectric sensor. The photoelectric sensor generates a position signal and feeds it back to the control mechanism, so that the control mechanism can determine the current position of the grain discharge control port and control the operation of the first drive mechanism, so that the grain discharge control port can selectively connect with any of the grain discharge ports.

[0011] According to the above scheme, the first drive mechanism includes a first drive motor, a drive wheel and a gear ring. The output shaft of the first drive motor is fixedly connected to the drive wheel, and the gear ring is fixed to the bottom of the rotating plate. The gear ring meshes with the drive wheel.

[0012] The first drive motor drives the drive wheel, which in turn drives the gear ring and the rotating plate to rotate synchronously, thereby improving the smoothness of the rotating plate's rotation.

[0013] According to the above solution, it also includes a base and a food storage bin. The food dispensing chamber is located inside the base, and the food storage bin is installed on the base. The bottom of the food storage bin has a food inlet communicating with the food dispensing chamber. Pet food in the food storage bin falls into the food dispensing chamber under the action of gravity.

[0014] According to the above scheme, the grain conveying component is driven to rotate by the second drive mechanism. The second drive mechanism includes a second drive motor and a rotating shaft. The first end of the rotating shaft is fixedly connected to the output shaft of the second drive motor. The second end of the rotating shaft passes through the rotating plate and the grain conveying component in sequence and extends into the grain storage tank and is fixedly connected to the grain stirring component.

[0015] By rotating the food agitator, the pet food stored in the food storage bin can flow out quickly from the food outlet.

[0016] According to the above scheme, the grain conveying component includes an upper baffle, the edge of which is provided with a notch, which passes sequentially below the grain outlet and above multiple grain outlets under the drive of the second driving mechanism; each bottom edge of the notch is fixedly connected with a side plate, and the multiple side plates, together with the bottom and side wall of the grain outlet cavity, form a quantitative space corresponding to the grain outlet; the upper baffle is used to close the grain outlet after the grain is discharged from the grain outlet.

[0017] It is understandable that, since pet food is in pellet form, the side plate adjacent to the side wall of the food dispensing chamber can contact the side wall of the food dispensing chamber, or there can be a certain gap; when there is a gap, as long as it is ensured that the gap does not allow the pet food to pass through and does not affect the pushing of the pet food in the metering space, it is acceptable.

[0018] When the notch on the upper baffle rotates to below the lower food inlet, pet food flows into the measuring space from the lower food inlet. Continuing to rotate the upper baffle will close the lower food inlet. When the notch on the upper baffle rotates above one of the food outlets, and the food dispensing control port rotates below that outlet, the pet food in the measuring space flows sequentially through that outlet and the food dispensing control port into the corresponding dispensing channel. The amount of pet food dispensed depends on the size of the measuring space. By setting this measuring space, a fixed amount of pet food can be dispensed.

[0019] According to the above scheme, a second position detection device electrically connected to the control mechanism is also included, the second position detection device being used to detect the rotational position of the notch.

[0020] According to the above scheme, the second position detection device includes a rotating component and an elastic switch. The rotating component is fixedly sleeved on the rotating shaft. The outer periphery of the rotating component is provided with a plurality of positioning cams that correspond to the lower grain inlet and the plurality of grain outlets respectively. When the notch rotates to the position below the lower grain inlet or above the grain outlet, the corresponding positioning cam presses the elastic switch.

[0021] When the positioning cam presses the elastic switch, the elastic switch generates a sensing signal and feeds it back to the control mechanism, which then controls the operation of the second drive motor.

[0022] According to the above scheme, it also includes a control panel located on the base, the control panel having control buttons, and the control panel being electrically connected to the control mechanism.

[0023] The above-described structure enables the control mechanism to receive external input signals and control the opening of designated feed channels to feed the corresponding bowls, thereby controlling the timing and / or quantity of feed dispensing.

[0024] According to the above scheme, the grain storage tank includes a lid, a body and a funnel-shaped bottom connected from top to bottom, and the bottom is located on the grain outlet cavity.

[0025] Users can easily add pet food to the storage bin by opening the lid. The bottom of the bin is funnel-shaped, which facilitates the flow of pet food from the bottom outlet into the outlet chamber.

[0026] The beneficial effects of this utility model are as follows: This invention uses a first position detection device linked with a control mechanism to detect and control the rotation position of the feed control port, thereby achieving automatic and precise opening of the designated feed channel, which is easy to operate. When two or more feed channels are configured, the opening and closing of each feed channel can be controlled in an orderly manner, effectively improving the convenience and order of feeding multiple pets and enhancing the user experience.

[0029] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0030] like Figure 1-9As shown, this utility model provides a pet feeder, including a food dispensing chamber 3, three food dispensing channels 4, and three food bowls 5. A food conveying component 6 is rotatably disposed inside the food dispensing chamber 3. The bottom of the food dispensing chamber 3 has three food outlets 31 that are connected one above and one below the inlets of the three food dispensing channels 4. The outlets of the three food dispensing channels 4 correspond one to one with the three food bowls 5. It also includes a rotating plate 7, a control mechanism (not shown in the figure), and a first position detection device 8. The rotating plate 7 covers the bottom surface of the food dispensing chamber 3 and has a food dispensing control port 71. The first position detection device 8 is used to detect the rotational position of the food dispensing control port 71. The control mechanism is electrically connected to the first position detection device 8 and a first drive mechanism 72. The first drive mechanism 72 drives the rotating plate 7 to rotate so that the food dispensing control port 71 can selectively connect with any of the food dispensing ports 31.

[0031] Because the rotating plate 7 covers the bottom surface of the food dispensing cavity 3, it blocks the food dispensing port 31, which is not connected to the food dispensing control port 71. The food conveying component 6 rotates inside the food dispensing cavity 3, thereby pushing the pet food in the food dispensing cavity 3 out of the food dispensing port 31 connected to the food dispensing control port 71. When the first drive mechanism 72 drives the food dispensing control port 71 to rotate above the designated food dispensing channel 4, the food dispensing channel 4 opens; the pet food in the food dispensing cavity 3, under the pushing action of the food conveying component 6 and its own gravity, passes through the food dispensing port 31, the food dispensing control port 71, and the food dispensing channel 4 in sequence before falling into the corresponding food bowl 5.

[0032] The first position detection device 8 is linked with the control mechanism to detect and control the rotation position of the feed control port 71, thereby realizing the automatic and precise opening of the designated feed channel 4, which is easy to operate. When two or more feed channels 4 are configured, the opening and closing of each feed channel 4 can be controlled in an orderly manner, effectively improving the convenience and order of multi-pet feeding and improving the user experience.

[0033] Furthermore, the first position detection device 8 includes a positioning plate 81 fixed to the rotating plate 7 and a photoelectric sensor 82. The positioning plate 81 is provided with three positioning openings 83 that correspond one-to-one with the grain outlet 31. When the grain outlet control port 71 rotates to communicate with one of the grain outlets 31, the corresponding positioning opening 83 rotates synchronously to the detection position of the photoelectric sensor 82.

[0034] When the grain discharge control port 71 rotates to connect with one of the grain discharge ports 31, the positioning opening 83 on the positioning plate 81, which is uniquely corresponding to the grain discharge port 31, rotates synchronously to the detection position of the photoelectric sensor 82. The photoelectric sensor 82 generates a position signal and feeds it back to the control mechanism, so that the control mechanism can determine the current position of the grain discharge control port 71 and control the operation of the first drive mechanism 72, so that the grain discharge control port 71 can selectively connect with any of the grain discharge ports 31.

[0035] Furthermore, the first drive mechanism 72 includes a first drive motor 721, a drive wheel 722, and a gear ring 723. The output shaft of the first drive motor 721 is fixedly connected to the drive wheel 722, and the gear ring 723 is fixed to the bottom of the rotating plate 7 and meshes with the drive wheel 722.

[0036] The first drive motor 721 drives the drive wheel 722, which in turn drives the gear ring 723 and the rotating plate 7 to rotate synchronously, thereby improving the smoothness of the rotation of the rotating plate 7.

[0037] Furthermore, it also includes a base 2 and a food storage bin 1. The food dispensing chamber 3 is located inside the base 2, and the food storage bin 1 is mounted on the base 2. The bottom of the food storage bin 1 has a food outlet 131 that communicates with the food dispensing chamber 3. Pet food in the food storage bin 1 falls into the food dispensing chamber 3 under the action of gravity.

[0038] Furthermore, the grain conveying component 6 is driven to rotate by the second drive mechanism 61. The second drive mechanism 61 includes a second drive motor 611 and a rotating shaft 612. The first end of the rotating shaft 612 is fixedly connected to the output shaft of the second drive motor 611. The second end of the rotating shaft 612 passes through the rotating plate 7 and the grain conveying component 6 in sequence and extends into the grain storage tank 1 and is fixedly connected to the grain stirring component 613.

[0039] By rotating the food agitator 613, the pet food stored in the food storage bin 1 can flow out quickly from the food outlet 131 as it rotates.

[0040] Furthermore, the grain conveying component 6 includes an upper baffle 62, the edge of which is provided with a notch 621. The notch 621 passes sequentially below the lower grain outlet 131 and above the three grain outlets 31 under the drive of the second driving mechanism 61. Each bottom edge of the notch 621 is fixedly connected to a side plate 63. The multiple side plates 63, together with the bottom and sidewall of the grain outlet cavity 3, form a quantitative space corresponding to the lower grain outlet 131. The upper baffle 62 is used to close the lower grain outlet 131 after the grain is discharged from the lower grain outlet 131.

[0041] When the notch 621 of the upper baffle 62 is rotated to below the feed inlet 131, pet food flows into the metering space from the feed inlet 131. Continuing to rotate the upper baffle 62 will close the feed inlet 131. When the notch 621 of the upper baffle 62 is rotated to above one of the feed outlets 31, and the feed control port 71 is rotated to below that feed outlet 31, the pet food in the metering space flows sequentially through that feed outlet 31 and the feed control port 71 into the corresponding feed dispensing channel 4. The amount of pet food dispensed depends on the size of the metering space. By setting this metering space, a metered output of pet food can be achieved.

[0042] Furthermore, it also includes a second position detection device 9 electrically connected to the control mechanism, the second position detection device 9 being used to detect the rotational position of the notch 621.

[0043] Furthermore, the second position detection device 9 includes a rotating component 91 and an elastic switch 92. The rotating component 91 is fixedly sleeved on the rotating shaft 612. The outer periphery of the rotating component 91 is provided with a plurality of positioning cams 93 corresponding to the lower grain inlet 131 and the three grain outlets 31 respectively. When the notch 621 rotates to the position below the lower grain inlet 131 or above the grain outlets 31, the corresponding positioning cam 93 presses the elastic switch 92.

[0044] When the positioning cam 93 presses the elastic switch 92, the elastic switch 92 generates a sensing signal and feeds it back to the control mechanism, which then controls the operation of the second drive motor 611 accordingly.

[0045] Furthermore, it also includes a control panel 21 disposed on the base 2, the control panel 21 having control buttons 211, and the control panel 21 being electrically connected to the control mechanism.

[0046] The above-described structure enables the control mechanism to receive external input signals and control the opening of the designated feed channel 4 to feed the corresponding food bowl 5, thereby controlling the timing and / or quantity of feed dispensing.

[0047] Furthermore, the grain storage hopper 1 includes a hopper lid 11, a hopper body 12, and a funnel-shaped hopper bottom 13 connected sequentially from top to bottom, with the hopper bottom 13 located on the grain outlet cavity 3.

[0048] Users can easily add pet food to the food storage container 1 by opening the lid 11. The bottom 13 of the container is funnel-shaped, which facilitates the flow of pet food from the food inlet 131 into the food outlet 3.

[0049] It is understood that the number of food outlets 31, food channels 4, food bowls 5, and positioning openings 83 are the same, and in this embodiment, they are set to three. In other embodiments, the number can be adjusted according to actual needs. To facilitate understanding of the structure and operation of the pet feeder by those skilled in the art, in this embodiment, the three food outlets 31 are labeled as the first food outlet 311, the second food outlet 312, and the second food outlet 313, respectively; the three food channels 4 are labeled as the first food channel 41, the second food channel 42, and the second food channel 43, respectively; the three food bowls 5 are labeled as the first food bowl 51, the second food bowl 52, and the second food bowl 53, respectively; the three positioning openings 83 are labeled as the first positioning opening 831, the second positioning opening 832, and the third positioning opening 833, respectively; and the four positioning cams 93 are labeled as the first positioning cam 931, the second positioning cam 932, the third positioning cam 933, and the fourth positioning cam 934, respectively.

[0050] The initial state of the pet feeder of this utility model is set as follows: the notch 621 of the upper baffle 62 is located at the transition position between the lower food outlet 131 and the third food outlet 313, and the food outlet control port 71 of the rotating plate 7 is located at the transition position between the first food outlet 311 and the third food outlet 313.

[0051] The following describes the working process of the pet feeder of this utility model, taking the designated feeding of food into the first food bowl 51 as an example: Add sufficient pet food to the food storage bin 1, and then press the control button 211 to receive an input signal from the control mechanism indicating that food should be dispensed into the first food bowl 51. The control mechanism controls the first drive motor 721 to drive the rotating plate 7 and the positioning plate 81 to rotate synchronously. When the food dispensing control port 71 on the rotating plate 7 rotates to below the first food dispensing port 311, the first positioning opening 831 on the positioning plate 81 rotates to the detection position of the photoelectric sensor 82. The photoelectric sensor 82 generates a position signal. After receiving the position signal, the control mechanism controls the first drive motor 721 to stop working, thereby connecting the food dispensing control port 71 with the first food dispensing port 311 and the first food dispensing channel 41 respectively. Then, the control mechanism controls the second drive motor 611 to drive the food conveying component 6 and the rotating component 91 to rotate synchronously. When the notch 621 on the upper baffle 62 rotates to below the lower food dispensing port 131, the fourth... The positioning cam 934 presses the elastic switch 92, which generates a sensing signal and feeds it back to the control mechanism. The control mechanism then controls the second drive motor 611 to stop working. The pet food in the food storage bin 1 flows into the metering space through the food outlet 131. After the metering space is filled with pet food for a certain period of time, the control mechanism controls the second drive motor 611 to continue working, and the upper baffle 62 continues to rotate. At this time, the food outlet 131 is closed by the upper baffle 62. When the notch 621 of the upper baffle 62 rotates to the top of the first food outlet 311, the first positioning cam 931 presses the elastic switch 92, which generates a sensing signal and feeds it back to the control mechanism. The control mechanism then controls the second drive motor 611 to stop working. At this time, the pet food in the metering space falls into the first food bowl 51 under the action of gravity, passing through the first food outlet 311, the food outlet control port 71, and the first food outlet channel 4 in sequence.

[0052] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
