Description

Technical Field

[0001] This invention relates to the field of pet supplies technology, and in particular to a pet feeder and its method of use. Background Technology

[0002] With the continuous development of pet food, there are more and more types of pet food. Among them, pet food is mainly divided into two categories: wet food and dry food. Wet food has a softer and more glutinous texture, making it easier for pets to chew and digest. It is especially suitable for senior pets, pets with dental problems, or pets with poor oral health. In addition, wet food has a relatively high water content, which can effectively help pets replenish water.

[0003] Currently, to ensure the freshness and safety of wet food feeding, existing pet feeders consist of a base, a rotating food dish on the base, and a top cover over the food dish. The top cover has a feeding opening that communicates with the food troughs of the food dish. Rotating the food dish connects one of the food troughs to the feeding opening for feeding the pet. However, the rotation of the food dish can easily cause the pet's paws or head to get stuck between the food troughs and the feeding opening, affecting the pet's feeding experience and even causing injury, resulting in low safety. Summary of the Invention

[0004] The purpose of this invention is to provide a pet feeder and its usage method, which has a simple structure, is easy to operate, has high feeding safety, and provides a good user experience.

The feeding assembly includes a drive component and a food tray, the food tray being disposed within the receiving groove, the food tray having multiple food slots evenly distributed around the rotation axis of the food tray, the drive component being kinetically connected to the food tray to drive the food tray to rotate; the cover is detachably connected to the base to seal the opening of the receiving groove, the cover having a feeding port communicating with the food slots, and a trigger component being provided on the cover. Rotating the cover along its own central axis by a specified angle causes the trigger component to activate the switch, and the switch is electrically connected to the drive component.

[0006] In one embodiment, the base is provided with a buckle, the cover is provided with an installation port, the buckle is snapped into the installation port, the switch is provided on the buckle, and the trigger is the cavity wall of the installation port, which can trigger the switch.

[0007] In one embodiment, the base has two latches spaced apart, each latch having a switch. Rotating the cover clockwise triggers the switch on one latch, and rotating the cover counter-clockwise triggers the switch on the other latch; or... The buckle is equipped with two switches. Rotating the cover clockwise can trigger one of the switches, and rotating the cover counterclockwise can trigger the other switch.

[0008] In one embodiment, the switch includes a micro switch and a slider. The buckle has a mounting groove on the side facing the base. The micro switch is installed in the mounting groove. A communication port is opened on the outer periphery of the buckle. The slider is slidably connected to the buckle, and part of the slider passes through the communication port and is connected to the trigger part of the micro switch.

[0009] In one embodiment, the connecting port has a first side surface arranged along a first direction, and the slider has a second side surface disposed adjacent to the first side surface. One of the two adjacent sides of the first side surface and the second side surface is provided with a first limiting groove, the length of which extends along a second direction. The other side is provided with a first positioning part, which is slidably connected to the first limiting groove. The two groove walls of the first limiting groove along the second direction can restrict the movement of the first positioning part. The first direction is perpendicular to the second direction.

[0010] In one embodiment, the base has a protrusion, the cover has a downward-facing enclosure, the protrusion is inserted into the enclosure, the switch is disposed on the protrusion, and the trigger is the cavity wall of the enclosure, which can trigger the switch; or A switch is provided on the base, and a protrusion is provided on the cover. The trigger is the protrusion, which can trigger the switch.

[0011] In one embodiment, the base includes a support portion and a boss protruding from the support portion. The top side of the boss is provided with the receiving groove. The buckle is provided on the outer periphery of the boss. The cover includes a top cover and a surrounding wall arranged circumferentially along the outer periphery of the top cover. The top cover is provided with the feeding port. The surrounding wall is provided with the mounting port. The surrounding wall is fitted over the boss and supported on the support portion.

[0012] In one embodiment, the outer periphery of the boss is recessed with a placement groove. The buckle includes an elastic element and a snap-fit ​​block. The elastic element connects the groove wall of the placement groove to the snap-fit ​​block. The elastic element always has a tendency to push the snap-fit ​​block into the mounting opening. The switch is located on one side of the snap-fit ​​block along the rotation direction of the cover. When the snap-fit ​​block is pressed, both the snap-fit ​​block and the switch can retract into the placement groove.

[0013] In one embodiment, the pet feeder further includes a temperature control component, which includes a first heat-conducting element, a thermoelectric cooler, a second heat-conducting element, and a heat dissipation mechanism. A heat dissipation cavity is provided within the base. A third limiting groove is recessed at the bottom of the receiving slot. The first heat-conducting element is disposed within the third limiting groove, and at least partially protrudes from the opening of the third limiting groove and abuts against the food dish. A fixing hole communicating with the heat dissipation cavity is provided at the bottom of the third limiting groove. The thermoelectric cooler is disposed within the fixing hole. The top of the thermoelectric cooler is connected to the first heat-conducting element, and the bottom of the thermoelectric cooler is connected to the second heat-conducting element. Both the second heat-conducting element and the heat dissipation mechanism are disposed within the heat dissipation cavity. An air inlet and an air outlet communicating with the heat dissipation cavity are also provided on the base. The heat dissipation mechanism is used to dissipate heat from the second heat-conducting element.

[0014] Secondly, a method for using a pet feeder is provided, comprising the following steps: S10. Store the food into each of the feeding troughs of the feeding plate; S20. The drive unit drives the food tray to rotate so that one of the food troughs faces the feeding opening, allowing the pet to pass through the feeding opening to eat the food in the food trough; and / or, The driving component drives the feeding tray to rotate, thereby separating the feeding trough from the feeding port, so that the cover protects the food in the feeding trough; S30. During the process of the driving member driving the food tray to rotate, the pet actively pushes the cover to rotate along its own rotation axis, or the pet is stuck between the feeding port and the food trough and is pushed by the driving member to drive the cover to rotate along its own rotation axis. The trigger member can trigger the switch to make the switch feedback the driving member to stop driving or drive in the opposite direction at a specified angle.

[0015] The beneficial effects of this invention are: This invention discloses a pet feeder that uses the connection between a cover and a base to seal the opening of the food trough, preventing external contamination of the food inside and ensuring that the pet can access healthy and safe food. When feeding is needed, a drive mechanism automatically rotates the food trough to align it with the feeding opening, allowing the pet to eat through the opening, making feeding convenient. The detachable design of the cover and base facilitates cleaning of both, helping to maintain the hygiene of the pet feeder. A switch allows the pet to trigger the switch when the food trough rotates or when the cover is actively pushed, prompting the drive mechanism to stop or rotate in the opposite direction by a specified angle. This prevents the pet's paws or head from getting stuck between the food trough and the feeding opening, reducing the risk of injury and providing a safe feeding environment.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0019] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0021] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0022] like Figures 1 to 6As shown, a pet feeder of this embodiment includes a base 1, a feeding component 4, and a cover 5. The top side of the base 1 is provided with a receiving groove 11, and a switch 3 is provided on the base 1. The feeding component 4 includes a drive member 41 and a food tray 42. The food tray 42 is disposed in the receiving groove 11 and is provided with a plurality of food troughs 421. All the food troughs 421 are evenly distributed around the rotation axis of the food tray 42. The drive member 41 is connected to the food tray 42 for driving the food tray 42 to rotate. The cover 5 is detachably connected to the base 1 to seal the opening of the receiving groove 11. The cover 5 is provided with a feeding port 52 communicating with the food troughs 421. The cover 5 can rotate a specified angle along its own central axis to trigger the switch 3. The switch 3 is electrically connected to the drive member 41.

[0023] It is understood that the pet feeder of the present invention uses the connection between the cover 5 and the base 1 to seal the opening of the receiving slot 11, preventing external contamination of the food in the food trough 421 of the food dish 42, ensuring that the pet can obtain healthy and safe food. When feeding is needed, the drive component 41 automatically drives the food dish 42 to rotate so that the food trough 421 is aligned with the feeding opening 52, allowing the pet to eat the food in the food trough 421 through the feeding opening 52, making feeding convenient. The detachable design of the cover 5 and the base 1 makes it easy to disassemble and clean the cover 5 and the food dish 42, helping to maintain the hygiene of the pet feeder. The switch 3 allows the pet to rotate the cover 5 by the food dish 42 or by actively pushing it, triggering the switch 3 to stop the drive component 41 or rotate it in the opposite direction by a specified angle, preventing the pet's paws or head from getting stuck between the food trough 421 and the feeding opening 52, reducing the risk of pet injury and providing a safe feeding environment.

[0024] Furthermore, a buckle 2 is provided on the base 1, and an installation port 51 is provided on the cover 5. The buckle 2 is snapped into the installation port 51, and the switch 3 is located on the buckle 2. The trigger element is the cavity wall of the installation port 51, which can trigger the switch 3. The buckle 2 and the installation port 51 are used to achieve a quick connection between the cover 5 and the base 1. At the same time, the switch 3 is located on the outer peripheral wall of the buckle 2, so that when the cover 5 rotates, the cavity wall of the installation port 51 can squeeze and trigger the switch 3, resulting in a good response effect. The installation port 51 can not only achieve the installation of the cover 5 and the base 1 by snapping with the buckle 2, but also act as a trigger element to respond to the switch 3.

[0025] Of course, in some embodiments, the trigger can also be a protrusion of the cover 5 facing the base 1, and the switch 3 is directly set on the side of the base 1 facing the cover 5. When the cover 5 rotates, the protrusion can press against the switch 3 and trigger the response mechanism. Alternatively, the buckle 2 and the switch 3 are spaced apart along the rotation direction of the cover 5. The cover 5 is provided with an installation port 51 that cooperates with the buckle 2, and at the same time, it is provided with a clearance port or a physical trigger block that cooperates with the switch 3. Further examples will not be given here.

[0026] In addition, the mating structure of the trigger and the switch 3 can also be that the base 1 is provided with a protrusion, the cover 5 is provided with a downward-facing enclosure, the protrusion is inserted into the enclosure, the switch 3 is provided on the protrusion, the trigger is the cavity wall of the enclosure, and the cavity wall of the enclosure can trigger the switch 3; the enclosure can be a wall structure protruding from the cover 5 or a groove structure.

[0027] Optionally, a switch 3 is provided on the base 1, and a protrusion is provided on the cover 5. The trigger is the protrusion, and the switch 3 can be triggered by rotating the protrusion on the cover 5.

[0028] In summary, this embodiment uses the cavity wall of the mounting port 51 as the trigger element, enabling the mounting port 51 of the cover 5 to achieve a snap-fit ​​connection. At the same time, rotating the cover 5 can trigger the switch by using the cavity wall of the mounting port 51, reducing the use of additional protruding structures, grooves, or openings as trigger elements, effectively improving the structural strength and manufacturing convenience of the cover 5.

[0029] In some embodiments, two latches 2 are spaced apart on the base 1, and each latch 2 is equipped with a switch 3. Rotating the cover 5 clockwise triggers the switch 3 on one latch 2, and rotating the cover 5 counterclockwise triggers the switch 3 on the other latch 2. This arrangement provides two mounting holes 51 on the cover 5, and the connection between the two latches 2 and the two mounting holes 51 enhances the stability of the connection between the cover 5 and the base 1. Furthermore, the switches 3 on the two latches 2 are positioned in opposite directions to the rotation of the cover 5, ensuring that whether the cover 5 is pushed by the pet or rotates clockwise or counterclockwise when the pet is positioned between the food bowl 421 and the feeding opening 52, the switch 3 on one latch 2 will be triggered, thus prompting the drive unit 41 to stop or rotate in the opposite direction by a specified angle. The drive unit 41 is a motor with high control precision. The motor is electrically connected to the switch 3 via a controller, resulting in a fast response speed.

[0030] Optionally, the latch 2 is equipped with two switches 3. Rotating the cover 5 clockwise will trigger one of the switches 3, and rotating the cover 5 counterclockwise will trigger the other switch 3. That is, whether the cover 5 is pushed by the pet or pushed by the pet when it is stuck between the food trough 421 and the feeding opening 52, rotating clockwise or counterclockwise will trigger one of the switches 3, thereby prompting the drive component 41 to stop or rotate in the opposite direction by a specified angle.

[0031] It should be noted that, in the normal connection state, the wall of the mounting port 51 of the cover 5 has a gap of 0.5-1.5mm, preferably 1mm, with the switch 3. When the cover 5 rotates, the cover 5 abuts against and continues to push to trigger the switch 3 feedback drive 41, thus forming a complete triggering mechanism. The cover 5 rotates, possibly due to the pet's paw pushing it, indicating the pet is already on the feeder. Alternatively, the pet's paw or head may have entered the food tray 421, causing the food tray 42 to rotate under the drive of the drive 41, pushing the pet's paw or head against the cover 5 and causing it to rotate. In these cases, the triggering mechanism of the cover 5 on the switch 3 can provide feedback to the drive 41 to continue driving. The switch 3 can be a push button switch 3, a micro switch 31, or other trigger-type switches 3; no further limitations are imposed here.

[0032] Furthermore, such as Figure 5 and Figure 6 As shown, switch 3 includes a micro switch 31 and a slider 32. A mounting groove 21 is provided on the side of the latch 2 facing the base 1. The micro switch 31 is installed into the mounting groove 21. A connecting port 22 is provided on the outer periphery of the latch 2. The slider 32 is slidably connected to the latch 2, and part of the slider 32 passes through the connecting port 22 to connect with the trigger part of the micro switch 31. This arrangement saves space, making the overall structure of the device more compact. Furthermore, the latch 2 effectively protects the micro switch 31 within the mounting groove 21, reducing the impact of accidental contact or impact and ensuring the service life of the micro switch 31. In addition, the slider 32 is slidably connected to the latch 2. In this embodiment, the slider 32 is slidably connected to the connecting port 22. The constraint of the cavity wall of the connecting port 22 improves the guiding and smooth movement of the slider 32.

[0033] Preferably, the connecting port 22 has a first side surface arranged along a first direction (the first direction is the X direction in the figure), and the slider 32 has a second side surface disposed adjacent to the first side surface. The first side surface is provided with a first limiting groove 23, the length of which extends along a second direction (the second direction is the Y direction in the figure). The second side surface is provided with a first positioning part 321, which is slidably connected to the first limiting groove 23. The two groove walls of the first limiting groove 23 along the second direction can restrict the movement of the first positioning part 321. The first direction is perpendicular to the second direction. By using the first limiting groove 23 to restrict the first positioning part 321, the slider 32 can maintain an accurate position during sliding, preventing the slider 32 from detaching from the connecting port 22, or from actively triggering the cover 5 under the elastic push of the micro switch 31 trigger part, or from being damaged by excessive pressure on the micro switch 31 under the push of the cover 5, thus improving the stability of the switch 3.

[0034] Of course, it is not limited to setting the first limiting groove 23 on the first side and setting the first positioning part 321 on the second side; it is also possible to set the first limiting groove 23 on the second side and set the first positioning part 321 on the first side. In this embodiment, the connecting port 22 has two first sides arranged along the first direction, and the slider 32 has two second sides arranged along the first direction, with the two first sides corresponding to the two second sides in a sliding connection.

[0035] Optionally, the bottom of the mounting groove 21 is provided with multiple support blocks 24, which together form a second limiting groove 25, into which the micro switch 31 is inserted. By providing balanced and stable support for the micro switch 31 through the arrangement of multiple support blocks 24, it is possible to effectively prevent the switch 31 from tilting or moving during use, thereby improving the installation accuracy and stability of the micro switch 31.

[0036] Furthermore, a limiting part 26 is provided at the end of the support block 24 away from the bottom of the mounting groove 21, and the micro switch 31 is engaged between the bottom of the second limiting groove 25 and the limiting part 26. By providing the limiting part 26, the micro switch 31 can be effectively prevented from dislodging from the opening of the second limiting groove 25, thereby improving the installation stability of the micro switch 31.

[0037] In some embodiments, such as Figure 2 , Figure 3 and Figure 4The base 1 includes a support portion 12 and a boss 13 protruding from the support portion 12. A receiving groove 11 is provided on the top side of the boss 13. A buckle 2 is provided on the outer periphery of the boss 13. The cover 5 includes a top cover 53 and a surrounding wall 54 arranged circumferentially along the outer periphery of the top cover 53. A feeding port 52 is provided on the top cover 53, and an installation port 51 is provided on the surrounding wall 54. The surrounding wall 54 is fitted over the boss 13 and supported on the support portion 12. Through the insertion and engagement of the surrounding wall 54 and the boss 13, i.e., the restriction between the inner side of the surrounding wall 54 and the outer periphery of the boss 13, the connection stability between the cover 5 and the base 1 can be effectively ensured, reducing the risk of tilting or shaking of the cover 5. Of course, in other embodiments, the buckle 2 can also be provided on the top side of the boss 13, without much restriction. It should be noted that the installation port 51 is not limited to a hole-like structure; it can also be an opening structure that penetrates the bottom side of the surrounding wall 54.

[0038] Preferably, the outer peripheral wall of the enclosure 54 and the outer peripheral wall of the support 12 are arranged to overlap in the vertical direction (the vertical direction is the Z direction shown in the figure, which is perpendicular to the first direction and the second direction), which reduces the protrusion of the structure and improves the aesthetics of the feeder.

[0039] Furthermore, a recessed placement groove 131 is provided on the outer periphery of the boss 13. The buckle 2 includes an elastic element 27 and a snap-fit ​​block 28. The elastic element 27 connects the groove wall of the placement groove 131 with the snap-fit ​​block 28. The elastic element 27 always has a tendency to push the snap-fit ​​block 28 into the mounting opening 51. The switch 3 is located on one side of the snap-fit ​​block 28 along the rotation direction of the cover 5. When the snap-fit ​​block 28 is pressed, both the snap-fit ​​block 28 and the switch 3 can retract into the placement groove 131. That is, by utilizing the elastic force of the elastic element 27, the snap-fit ​​block 28 can always be in the snap-fit ​​state of the mounting opening 51 to ensure the connection stability between the cover 5 and the base 1. The elastic element 27 can be directly a spring, a purely mechanical structure, which can drive the snap-fit ​​block 28 to stably snap into the mounting opening 51 without additional power consumption.

[0040] Of course, a stop should be provided on the cavity wall of the placement groove 131. The stop is located near the opening of the placement groove 131. Part of the snap-fit ​​block 28 is restricted between the bottom of the placement groove 131 and the stop, so as to prevent the snap-fit ​​block 28 from falling out of the placement groove 131 and improve the installation stability of the snap-fit ​​block 28.

[0041] Preferably, the snap-fit ​​block 28 is provided with an inclined surface. The inclined surface connects the top surface of the snap-fit ​​block 28 and the side of the snap-fit ​​block 28 away from the boss 13 and is inclined downward. When the cover 5 is installed, the enclosure wall 54 abuts against the inclined surface and pushes the inclined surface to slide, so that the snap-fit ​​block 28 overcomes the spring force and retracts into the placement groove 131 until the installation opening 51 is aligned with the groove opening of the placement groove 131. The snap-fit ​​block 28 is disengaged from the abutment of the enclosure wall 54 and inserted into the installation opening 51 under the action of the spring, making the connection convenient.

[0042] It's worth noting that pet feeders can hold wet food and keep it fresh. Of course, dry food can also be used; there are no major restrictions.

[0043] Furthermore, such as Figure 3 and Figure 4 As shown, the pet feeder also includes a temperature control component 6, which includes a first heat-conducting element 61, a semiconductor cooling chip 62, a second heat-conducting element 63, and a heat dissipation mechanism 64. A heat dissipation cavity 14 is provided in the base 1. A third limiting groove is provided in the recessed bottom of the receiving groove 11. The first heat-conducting element 61 is disposed in the third limiting groove, and at least part of the first heat-conducting element 61 is exposed at the opening of the third limiting groove and abuts against the food tray 42. A fixing hole communicating with the heat dissipation cavity 14 is provided at the bottom of the third limiting groove. The semiconductor cooling chip 62 is disposed in the fixing hole. The top of the semiconductor cooling chip 62 is connected to the first heat-conducting element 61, and the bottom of the semiconductor cooling chip 62 is connected to the second heat-conducting element 63. The second heat-conducting element 63 and the heat dissipation mechanism 64 are both disposed in the heat dissipation cavity 14. An air inlet 15 and an air outlet 16 communicating with the heat dissipation cavity 14 are also provided on the base 1. The heat dissipation mechanism 64 is used to dissipate heat from the second heat-conducting element 63.

[0044] In other words, the semiconductor cooling chip 62, also known as the thermoelectric semiconductor cooling chip 62, is controlled by a controller to heat or cool down when powered on, thus achieving cooling or heating. When cooling and preservation are required, the controller controls the cooling end of the semiconductor cooling chip 62 to cool down; when heating is required, the controller controls the heating end of the semiconductor cooling chip 62 to heat up. The heating function can be achieved without additional heating structures, resulting in a relatively simple overall structure. Furthermore, the cold or heat generated by the semiconductor cooling chip 62 is transferred to the food tray 42 through the first heat conductor 61, thereby maintaining the temperature of the wet grain within the food tray 42 within a certain range. This prevents some areas of the wet grain from becoming too hot while others become too cold, thus achieving a better preservation effect.

[0045] Since wet food is placed in the troughs 421 of the food dish 42, when the food dish 42 rotates under the drive of the drive unit 41, it causes the wet food in the troughs to rotate as well. When one of the troughs 421 aligns with the feeding opening 52, it is convenient for the pet to eat the wet food in that trough. Since each trough 421 contains wet food, once the wet food in one trough is consumed, the food dish 42 continues to rotate until the next trough 421 aligns with the feeding opening 52. That is, through the relative rotation between the food dish 42 and the cover 5, a particular trough 421 can be selectively aligned with the feeding opening 52, achieving the purpose of selective feeding. It can be understood that the food dish 42 moves while the cover 5 remains stationary.

[0046] In this embodiment, the semiconductor cooling chip 62 is mainly used to cool and preserve the food bowl. Therefore, a second heat-conducting element 63 is provided at the bottom of the semiconductor cooling chip 62. The second heat-conducting element 63 is composed of multiple heat-conducting blocks. The heat dissipation mechanism 64 can be used to blow air through the air inlet to draw in room temperature air, so that the heat on the heat-conducting blocks flows and is discharged from the air outlet, thereby achieving efficient heat dissipation and ensuring the cooling and preservation effect of the semiconductor cooling chip 62 on the food plate 42.

[0047] In other embodiments, the feeding dish 42 is provided with multiple feeding areas, all of which are evenly distributed around the rotation axis of the feeding dish 42. At least one feeding area is a blocking part 422, and each of the other feeding areas is provided with a corresponding feeding trough 421. When the feeding dish 42 rotates, the blocking part 422 blocks the feeding opening 52, or the feeding trough 421 communicates with the feeding opening 52. With this arrangement, when the pet does not need to eat, the blocking part 422 can block the feeding opening 52, so that all feeding troughs 421 are within the receiving cavity formed by the sealing receiving groove 11 of the cover body 5, ensuring the cleanliness of the feeding troughs 421.

[0048] like Figures 1 to 6 As shown, embodiments of the present invention also provide a method of using a pet feeder, the pet feeder comprising the following steps: S10. Store the food into the feeding troughs 421 of the feeding plate 42; S20, the drive unit 41 drives the food tray 42 to rotate so that one of the food troughs 421 is opposite to the feeding opening 52, so that the pet can pass through the feeding opening 52 to eat the food in the food trough 421. The drive unit 41 drives the feeding tray 42 to rotate, so that the feeding trough 421 is separated from the feeding port 52, so that the cover 5 protects the food in the feeding trough 421; S30. During the process of the drive unit 41 driving the food tray 42 to rotate, the pet actively pushes the cover 5 to rotate along its own rotation axis, or the pet is stuck between the feeding port 52 and the food trough 421 and is pushed by the drive unit 41 to drive the cover 5 to rotate along its own rotation axis. The trigger unit can trigger the switch 3, so that the switch 3 can feed back to the drive unit 41 to stop driving or drive in the opposite direction to a specified angle.

[0049] Understandably, by setting the switch 3, when the pet rotates the food bowl 42 or actively pushes the cover 5 to rotate, the trigger element can trigger the switch 3 to feed back the drive element 41 to stop driving or rotate in the opposite direction by a specified angle, so as to prevent the pet's paws or head from getting stuck between the food bowl 421 and the feeding opening 52, reduce the risk of pet injury, and provide a safe feeding environment.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
