[0031] In actual application of this embodiment, when the device is used to feed pets, the basin groove 102 provided on the base 101 is used to place the food bowl 301, and the limiting groove 103 on the basin groove 102 is engaged with the positioning pin 304 on the food bowl 301 to limit the rotation of the food bowl 301 in the basin groove 102, the food box 104 is used to fill the pet food to be fed, the lower food port 105 is inserted in the material guide shell 501, and is used to release the pet food from the material guide shell 501, the pedal 201 is rotatably installed on the base 101 and movably connected with the coupling rod 202, The coupling rod 202 is elastically slidably assembled on the base 101 along the first direction x. When the pet is ready to eat, the pet's forelimbs press on the pedal 201, which can make the pedal 201 rotate under the pressure, so that the coupling rod 202 can overcome the elastic force and slide. During the sliding process, the coupling rod 202 can be linked to open and close the feed inlet 502 and the discharge port 503 at both ends of the material guide shell 501, so that the pet food filled in the food box 104 passes through the material guide shell 501 and is released into the food bowl 301, so that the pet can eat the food. When the pet finishes eating and leaves the pedal 20 1 side, the pedal 201 lacks the pressure of the pet's weight, so the coupling rod 202 slides in the negative direction of the first direction x under the action of elastic force, so that the pedal 201 rotates and resets, and the lifting block 204 on the limit seat 203 moves in the positive direction of the second direction y under the linkage action, so that the lifting shaft 402 rotatably assembled on the lifting block 204 moves in the positive direction of the second direction y synchronously, so that the blocking plate 403 at the end of the lifting shaft 402 rises from the reflux hole 302, and a gap is formed between the blocking plate 403 and the reflux hole 302, so that The remaining food in the food bowl 301 can pass through the gap and fall onto the return plate 401, and the return plate 401 is tilted so that the food can slide on the return plate 401, and during the sliding process, the crushed residue is sieved out by the sieve holes 406, so that the unbroken food slides along the return plate 401 to the reflux cavity 407 for recovery, and the sieved food residue passes through the sieve holes 406 and falls onto the residue collecting plate 106 for collection. The food recovered into the reflux cavity 407 can be released into the food bowl 301 again during the subsequent food supply process, which can effectively prevent the pet food from getting damp and moldy or attracting flying insects in the air.

[0032] Furthermore, the inner wall of the food bowl 301 is funnel-shaped, so that the food contained therein automatically converges to the side of the reflux hole 302 under the action of gravity, which is convenient for the pet to eat on the one hand, and is convenient for recovering the food when the blocking plate 403 rises on the other hand.

[0033] See also Figure 5In a preferred embodiment of the present invention, the pedal assembly 2 further comprises a flap 205, wherein the flap 205 is elastically rotatably assembled on the coupling rod 202, the flap 205 has a first surface a1 and a second surface a2, and the lifting block 204 has a third surface a3.

[0034] In actual application of this embodiment, the flap 205 is elastically rotatably mounted on the coupling rod 202, and a groove matching the flap 205 is provided on the coupling rod 202. When the coupling rod 202 moves in the positive direction of the first direction x, the second surface a2 on one side of the flap 205 slides and abuts against the bottom surface of the lifting block 204, so that the flap 205 overcomes the elastic force and rotates and shrinks into the groove. At this time, the position of the lifting block 204 in the second direction y remains unchanged, so that the blocking disk 403 is always engaged in the reflux hole 302 to prevent the food released into the food bowl 301 from falling; when the coupling rod 202 moves in the negative direction of the first direction x, the first surface a1 abuts against the edge between the third surface a3 and the lower bottom surface of the lifting block 204, so that the lifting block 204 is lifted in the second direction y. When the flap 205 rotates counterclockwise to the limit position, the flap 205 and the coupling rod 202 remain vertical, and at this time, the first surface a1 is slidably connected with the lower bottom surface of the lifting block 204. During this process, the lifting shaft 402 lifts the blocking plate 403 along the second direction y to form a gap between the blocking plate 403 and the reflux hole 302, so that the remaining food in the food bowl 301 falls along the gap onto the reflux plate 401. When the flap 205 slips off the bottom of the lifting block 204, the flap 205 is reset to the initial position under the action of elastic force, and the lifting block 204 descends under the action of gravity, and pulls the lifting shaft 402 and the blocking plate 403 to descend synchronously, thereby driving the blocking plate 403 to movably block the reflux hole 302.

[0035] See also Figure 3 In a preferred embodiment of the present embodiment, the food bowl assembly 3 also includes a gear ring 303, and the reflux assembly 4 also includes a guide sleeve 404 and an insertion rod 405. The gear ring 303 is fixedly arranged in the inner diameter of the reflux hole 302, and several guide sleeves 404 are circumferentially fixedly assembled on the lifting shaft 402, and the guide sleeve 404 is elastically slidably assembled with an insertion rod 405.

[0036] In actual application of this embodiment, a gear ring 303 is provided on the inner wall side of the reflux hole 302, and a guide sleeve 404 and an insertion rod 405 are provided on the outer diameter side of the lifting shaft 402. Therefore, when the lifting block 204 is lifted in the second direction y, the lifting shaft 402 can drive the guide sleeve 404 thereon to move to the same horizontal height position as the gear ring 303 during the movement. When the lifting shaft 402 is in a rotating state, one end of the insertion rod 405 is movably abutted against the gear ring 303, and the other end of the insertion rod 405 elastically slides in the guide sleeve 404, so that continuous vibration is generated between the gear ring 303 and the insertion rod 405. On the one hand, the food bowl 301 is knocked to make the food adhered to the cavity wall of the food bowl 301 fall off. On the other hand, the vibration prevents the material from getting stuck in the reflux hole 302, and at the same time, the food that falls onto the reflux plate 401 can quickly slide into the reflux cavity tube 407.

[0037] See also Fig.10 In a preferred embodiment of the present invention, the pedal assembly 2 also includes a toothed plate 206, a ratchet 207, a driving bevel gear 208, a transmission bevel gear 209 and a synchronous belt 210. The toothed plate 206 is fixedly connected to the coupling rod 202 and is arranged along the first direction x.

One end of the synchronous belt 210 is transmission-connected to the transmission bevel gear 209, and the other end of the synchronous belt 210 is transmission-connected to the lifting shaft 402.

[0038] In actual application of this embodiment, the tooth plate 206 is fixedly assembled on one side of the coupling rod 202, and when the coupling rod 202 and the tooth plate 206 move in the positive direction of the first direction x, there is no transmission connection between the tooth plate 206 and the ratchet 207. When the coupling rod 202 and the tooth plate 206 move in the negative direction of the first direction x, the tooth plate 206 and the ratchet 207 are meshed and connected, so that the driving bevel gear 208 on the coaxial side of the ratchet 207 rotates synchronously. In the process of meshing and connecting with the transmission bevel gear 209, the driving bevel gear 208 drives the return shaft 408 to rotate synchronously through the rotation of the transmission bevel gear 209, and the synchronous belt 210 at one end of the transmission bevel gear 209 is transmission-connected with the lifting shaft 402, so it can also drive the lifting shaft 402 to rotate on a fixed axis, so that during the rotation of the lifting shaft 402, the several plug rods 405 assembled thereon can rotate and abut with the gear ring 303 and generate vibration.

[0039] See also Figure 6In a preferred embodiment of the present invention, the reflux component 4 also includes a reflux cavity tube 407, a reflux shaft 408, a reflux screw 409 and a reflux port 410.

The reflux screw 409 is assembled on the reflux shaft 408. The reflux port 410 is arranged at the top of the reflux cavity tube 407 and is arranged in the material guide shell 501.

[0040] In actual application of this embodiment, when the coupling rod 202 moves in the negative direction of the first direction x, the tooth plate 206 is meshed with the ratchet 207 to make the driving bevel gear 208 and the transmission bevel gear 209 rotate synchronously, and the transmission bevel gear 209 synchronously drives the reflux shaft 408 to rotate during the rotation process, and the reflux shaft 408 can synchronously drive the reflux screw 409 thereon to rotate during the rotation process. Due to the gap between the reflux screw 409 and the inner cavity wall of the reflux cavity tube 407, the reflux screw 409 slides and falls along the reflux plate 401. The grain in the reflux chamber 407 can continuously rise along the second direction y through the rotation of the reflux screw 409, and a reflux port 410 is also provided at the top of the reflux chamber 407, and the reflux port 410 is provided in the material guide shell 501, and the setting direction of the reflux port 410 is toward the side of the discharge port 503, so that when the reflux shaft 408 rotates, the grain in the reflux chamber 407 can be output along the reflux port 410 to the material guide shell 501, and temporarily stored in the cavity of the material guide shell 501 until it is synchronously output when the grain is released next time.

At the same time, since the second driven groove 604 is slidably connected with the discharge push rod 607, and the discharge baffle 608 at one end of the discharge push rod 607 is slidably inserted into the slot 504, when the opening and closing ring 601 rotates counterclockwise, the discharge orifice 609 on the discharge baffle 608 slides to the inner side of the cavity of the material guide shell 501, so that the pet food input into the material guide shell 501 can pass through the discharge orifice 609 and fall into the food bowl 301, thereby completing the release of the pet food.

[0043] See also Figure 7 and Figure 8 In a preferred embodiment of the present invention, the pet feeding device further comprises a transmission assembly 7, which comprises an L-shaped push plate 701, a stop plate 702, a first transmission plate 703, a damper 704, a second transmission plate 705, a central gear 706 and a frame 709. The L-shaped push plate 701 is slidably assembled in the base 101 along the first direction x and is movably abutted against the opening and closing push rod 602. The stop plate 702 is fixedly arranged at one end of the L-shaped push plate 701. The first transmission plate 703 and the second transmission plate 705 are They are all slidably arranged in the base 101 along the first direction x, and the first transmission plate 703 is elastically slidably connected to the L-shaped push plate 701, the damper 704 is fixedly arranged in the base 101 and connected to the first transmission plate 703, the central gear 706 is arranged between the first transmission plate 703 and the second transmission plate 705 and is meshed and connected with the first transmission plate 703 and the second transmission plate 705 respectively, one end of the frame 709 is movably connected to the second transmission plate 705, and the other end of the frame 709 is fixedly connected to the coupling rod 202.

[0044] In actual application of this embodiment, the L-shaped push plate 701 is slidably assembled in the base 101 along the first direction x. When the pet presses on the pedal 201, the coupling rod 202 linked to the pedal 201 and the frame 709 fixedly connected to the coupling rod 202 both move in the positive direction of the first direction x. Since the second transmission plate 705 is slidably assembled on the frame 709 along the second direction y, and the first transmission plate 703 and the second transmission plate 705 are both meshed with the middle gear 706, the movement of the second transmission plate 705 in the first direction x can The first transmission plate 703 is driven to move in the negative direction of the first direction x. At this time, the first transmission plate 703 synchronously pushes the L-shaped push plate 701 to move in the negative direction of the first direction x through the elastic force, and when the L-shaped push plate 701 moves to the extreme position and abuts against the stop plate 702, the L-shaped push plate 701 pushes the opening and closing push rod 602 to move to the extreme position, so that the feed port 502 and the discharge port 503 at both ends of the material guiding shell 501 are in an open state, thereby continuously releasing the pet food in the food box 104 into the food bowl 301 along the material guiding shell 501.

[0045] Furthermore, when the second transmission plate 705 continues to move in the positive direction of the first direction x, the distance between the first transmission plate 703 and the L-shaped push plate 701 is continuously reduced, and the spring between the L-shaped push plate 701 and the first transmission plate 703 is continuously compressed, and the movement stroke of the coupling rod 202 and the second transmission plate 705 in the first direction x is related to the weight of the pet. Therefore, according to pets of different weights, the movement stroke of the coupling rod 202 and the second transmission plate 705 in the first direction x is different, and when the second transmission plate 705 moves to the limit point of the stroke, the distance between the first transmission plate 703 and the damper 704 matches the movement stroke of the second transmission plate 705. Therefore, the greater the weight of the pet, the longer the movement stroke distance of the second transmission plate 705. Therefore, the first transmission plate 703 is under the elastic force. When the first transmission plate 703 moves in the positive direction of the first direction x under the action, due to the influence of the damping on one side of the damper 704, the time required for the first transmission plate 703 to be consumed in the resetting process is related to its movement stroke. Therefore, the greater the weight of the pet, the longer the resetting stroke, that is, the longer the resetting time. During the resetting process, since the L-shaped push plate 701 elastically abuts against the stop plate 702, the feed port 502 and the discharge port 503 at both ends of the material guide shell 501 are in an open state, so that food is continuously released into the food bowl 301. When the elastic force between the first transmission plate 703 and the L-shaped push plate 701 disappears, the first transmission plate 703 switches the feed port 502 and the discharge port 503 to a closed state when pulling the L-shaped push plate 701 to move, so that the device can control the release amount of pet food according to the weight of the pet, thereby achieving the purpose of reasonable feeding.

[0046] Furthermore, the transmission assembly 7 also includes a one-way toothed plate 707 and a top support rod 708. The one-way toothed plate 707 is arranged on one side of the second transmission plate 705, one end of the top support rod 708 is rotatably connected to the first transmission plate 703, and the other end of the top support rod 708 slides against the one-way toothed plate 707. When the first transmission plate 703 is subjected to the elastic force and moves in the positive direction of the first direction x, since the end of the top support rod 708 is buckled on the one-way toothed plate 707, the first transmission plate 703 can push the second transmission plate 705 toward the side away from the first transmission plate 703 through the top support rod 708 during the movement, so as to separate the meshing connection between the second transmission plate 705 and the middle gear 706. Since the position of the second transmission plate 705 in the first direction x remains basically unchanged when the pet presses on the pedal 201, the first transmission plate 703 is not interfered by the second transmission plate 705 during the reverse movement by separating the meshing connection between the second transmission plate 705 and the middle gear 706.

[0047] Furthermore, the transmission assembly 7 further includes a locking arm 710, a locking plate 711 and a reset column 712. The locking arm 710 is fixedly arranged at one end of the second transmission plate 705. One end of the locking plate 711 is rotatably assembled on the frame 709. The other end of the locking plate 711 is buckled with the locking arm 710. The reset column 712 is fixedly arranged in the base 101. When the second transmission plate 705 slides along the negative direction of the second direction y under the pressure of the top support rod 708, the locking arm 711 at one end of the second transmission plate 705 0 synchronously slides on one side of the locking plate 711, and the locking arm 710 is limitedly buckled on the locking plate 711, thereby limiting the reset of the second transmission plate 705 in the second direction y, so that when the pedal 201 shakes during the pet's eating, the second transmission plate 705 and the middle gear 706 are no longer engaged for transmission, thereby preventing the L-shaped push plate 701 from being clamped on one side of the stop plate 702, so that the feed port 502 and the discharge port 503 are in an open state for a long time, resulting in continuous release of pet food in the food box 104.

[0048] The above embodiment of the present invention provides a feeding device for pets. By providing a pedal 201 at one end of a base 101 and providing a food bowl 301 with a hollow structure in the base 101, the output of food can be controlled according to the action of the pet pressing the pedal 201, and the food can be quantitatively output according to the weight of the pet. After the pet finishes eating, the remaining food in the food bowl 301 can be recycled, thereby preventing the food from getting damp and moldy or attracting flying insects in the air.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
