In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0081] As shown in Figure 1 , Figure 2 and Figure 3 , the present embodiment provides a pet feeder, which comprises a base 1, a waste bin 2, a support 3, a discharging mechanism 4, a clamping mechanism 5 and a feeding mechanism 6.

[0082] The base 1 is provided with a mounting cavity 111 and a feeding opening 131; the waste bin 2 is mounted in the mounting cavity 111 and is provided with a waste grain inlet 21; the support 3 is provided on the base 1 and is provided with a grain cavity 311 for storing pet food. In combination with Figure 4 and Figure 5 , the discharging mechanism 4 comprises a grain discharging piece 43 and a pressing piece 44, the grain discharging passage of the grain discharging piece 43 is communicated with the grain cavity 311, and the grain discharging piece 43 is at least partially made of flexible material to discharge under the pressing action of the pressing piece 44. The clamping mechanism 5 is used to clamp and seal the flexible part of the grain discharging piece 43 to prevent air from entering the grain discharging piece 43.

[0083] The feeding mechanism 6 comprises a conveying belt 61 which is conveyingly arranged on the base 1 and is located below the feeding opening 131 and the discharging member 43. The feeding opening 131 and the conveying belt 61 define a feeding area 7 in which the pet eats. The pet food falls on the conveying belt 61 through the discharging member 43, and the conveying belt 61 is used to convey the pet food to the feeding area 7 and to convey the waste food in the feeding area 7 to the waste food inlet 21.

[0084] During discharging, the clamping mechanism 5 releases the discharging member 43, and the extrusion member 44 extrudes the discharging member 43 to realize discharging. After the first discharging is completed, the clamping mechanism 5 clamps the discharging member 43 again until the next time of discharging. This prevents air from entering from the outlet of the discharging member 43, and ensures that the remaining food stored in the feeder is always in a dry and sealed environment. The pet food output from the outlet of the discharging member 43 falls on the conveying belt 61 below, and then the conveying belt 61 conveys the output pet food to the feeding area 7 for the pet to eat. After the pet eats, the conveying belt 61 moves again to convey the remaining waste food in the feeding area 7 to the waste food inlet 21 and then into the waste food bin 2. This can avoid the pet eating the remaining pet food which has been placed in the feeding area for a long time, and ensure that the pet eats healthily.

[0085] In this embodiment, referring to Figure 1 , Figure 2 and Figure 3 , the support 3, the discharging mechanism 4 and the clamping mechanism 5 jointly constitute a discharging unit which is arranged on the base 1. The support 3 comprises an internal food rack 31 and an outer cover 32 which is arranged outside the food rack 31. The food rack 31 is provided with the food cavity 311 described above, and the food cavity 311 is in a funnel shape to ensure smooth discharging.

[0086] Referring to Figure 5 , the discharging mechanism 4 further comprises a feeding member 41 and a fixing frame 42. The fixing frame 42 is installed on the food rack 31, and the feeding member 41 is arranged through the upper end of the fixing frame 42 and extends into the food cavity 311. The discharging member 43 comprises a connecting cylinder 431, a flexible cylinder 432 and a discharging nozzle 433 which is arranged on the bottom surface of the flexible cylinder 432 in sequence from top to bottom. The diameter of the connecting cylinder 431 is larger than that of the flexible cylinder 432. The connecting cylinder 431 is arranged through the lower end of the fixing frame 42. The inner cavity of the feeding member 41, the inner cavity of the fixing frame 42 and the inner cavity of the discharging member 43 are in sequence communication to realize discharging.

[0087] In the embodiment, the extruding member 44 is realized by the flexible cylinder 432 to discharge the pet food from the outlet of the discharge nozzle 433. Further, the discharge nozzle 433 is also made of flexible material, and the clamping mechanism 5 is realized by clamping the discharge nozzle 433 to realize sealing. The connecting cylinder 431 is made of flexible material or rigid material, and can realize connection with the fixed frame 42. Exemplarily, the connecting cylinder 431, the flexible cylinder 432 and the discharge nozzle 433 are all made of silica gel material, and the whole discharging member 43 is integrally formed, which is convenient to manufacture and does not need to be assembled later.

[0088] In the embodiment, the inner cavity of the discharge nozzle 433 is gradually reduced from top to bottom. When the clamping mechanism 5 does not clamp the discharge nozzle 433, the discharge nozzle 433 can block the pet food from flowing out under the action of its own gravity, and only when the extruding member 44 extrudes the discharging member 43, the discharge nozzle 433 can discharge. Exemplarily, the discharge nozzle 433 is in a flat conical structure, which can prevent the pet food from flowing out under the action of its own gravity. Of course, the discharge nozzle 433 can also be in an inverted conical shape or other arbitrary shape, as long as it can be clamped and sealed by the clamping mechanism 5 and can smoothly discharge under the extrusion of the extruding member 44, which is within the protection scope of the present application, and the specific shape of the discharge nozzle 433 is not limited here.

[0089] Referring to Figure 5 and Figure 6 , the discharging mechanism 4 further comprises a first driving assembly 45 arranged on the support 3. The extruding member 44 is provided with a pushing part 441, a rotating shaft 442 and a pressing rod 443. The extruding member 44 is rotatably connected to the support 3 through the rotating shaft 442. The pushing part 441 and the pressing rod 443 are arranged on the two sides of the rotating shaft 442. The first driving assembly 45 is used to push the pushing part 441, so that the pressing rod 443 is upwardly buckled to extrude the bottom surface of the flexible cylinder 432. After the flexible cylinder 432 is extruded and deformed, the pet food in the inside is output through the discharge nozzle 433 under the extrusion. The end of the pressing rod 443 away from the rotating shaft 442 is upwardly bent and extended, and a flat surface for contacting the flexible cylinder 432 is arranged at the end, which is more labor-saving when extruding. Further, the pressing rod 443 is arranged in two, and the two pressing rods 443 are arranged on the two sides of the discharge nozzle 433 to jointly extrude the flexible cylinder 432 to realize fast and uniform discharging.

[0090] Optionally, the first driving assembly 45 comprises a first rotating driving member 451 and a first driving wheel 452. The first rotating driving member 451 is arranged on the support 3; the first driving wheel 452 is eccentrically connected to an output end of the first rotating driving member 451, and rotates eccentrically under the driving of the first rotating driving member 451; the outer circumferential surface of the first driving wheel 452 is in sliding abutment with the pushing part 441; when the first driving wheel 452 rotates eccentrically, the pushing part 441 is pushed to make the top pressing rod 443 on the other side upwarp to press the flexible cylinder 432 or the lower swing to release the flexible cylinder 432. The weight of one side of the top pressing rod 443 is greater than that of one side of the pushing part 441, so that the pushing part 441 is always in contact with the first eccentric driving wheel 513 during the rotation of the first eccentric driving wheel 513.

[0091] In the embodiment, the first rotating driving member 451 is a rotating motor.

[0092] In other embodiments, the first driving assembly 45 can also be a linear driving assembly, such as a pneumatic cylinder, an electric push rod, etc., which can push the pushing part 441 to make the top pressing rod 443 upwarp through the telescopic rod.

[0093] The specific structure of the clamping mechanism 5 will be described below with reference to Figure 5 , Figure 7 and Figure 8 .

[0094] The clamping mechanism 5 comprises a second driving assembly 51, a pull rod assembly 52 and clamping arms 53. The housing of the second driving assembly 51 is connected to the support 3. One end of the pull rod assembly 52 is connected to the output end of the second driving assembly 51, and the other end is provided with two guide columns 521 at intervals. The pull rod assembly 52 moves along its own axis under the driving of the second driving assembly 51. The clamping arms 53 are provided in two, and the two clamping arms 53 are arranged on the two sides of the grain discharging member 43. One end of the clamping arm 53 is rotatably connected to the support 3, and the other end is provided with a clamping surface 531. The clamping arm 53 is provided with a guide hole 532, which is at least partially inclined relative to the moving direction of the pull rod assembly 52. The guide columns 521 are correspondingly arranged in the guide holes 532 of the two clamping arms 53 and are in slidable cooperation with the corresponding guide holes 532. When the second driving assembly 51 drives the pull rod assembly 52 to move along its own axis, the guide columns 521 slide in the corresponding guide holes 532, and the one end of the two clamping arms 53 is rotated relative to the support 3 by pushing the hole wall of the guide hole 532. When the two clamping arms 53 rotate relative to each other, the discharge nozzle 433 of the grain discharging member 43 is clamped by the clamping surface 531, thereby achieving sealing.

[0095] Further, see Figure 7Each guide hole 532 includes a first hole section 5321 and a second hole section 5322 in communication, the first hole section 5321 is parallel to the axis of the pull rod assembly 52, the second hole section 5322 is inclined to the first hole section 5321, and the distance between the two second hole sections 5322 gradually increases in the direction away from the first hole section 5321. When the guide column 521 slides in the first hole section 5321, the two clamping arms 53 are in different positions, after entering the second hole section 5322, the two clamping arms 53 are pushed to rotate relatively, and the discharge nozzle 433 is clamped by the clamping surface.

[0096] Referring to Figure 5 The upper surface of one of the two clamping arms 53 is provided with a clamping block 533, and the lower surface of the other is provided with a clamping block 533, the two clamping blocks 533 are used to clamp the discharge nozzle 433, increase the contact area of the clamping arms 53 and the discharge nozzle 433, and ensure better sealing after clamping.

[0097] Referring to Figure 8 The second driving assembly 51 includes a second rotary driving member 511 and a second driving wheel 512. The housing of the second rotary driving member 511 is arranged on the support 3; the second driving wheel 512 is coaxially connected to the output end of the second rotary driving member 511, the first eccentric driving wheel 513 is eccentrically arranged on the second driving wheel 512, one end of the pull rod assembly 52 is provided with a first driven ring 523, the first eccentric driving wheel 513 is slidably arranged in the first driven ring 523, and the other end of the pull rod assembly 52 is provided with a connecting block 522, and the two guide columns 521 are protrudingly arranged on the connecting block 522.

[0098] When the second rotary driving member 511 drives the second driving wheel 512 to rotate, the first eccentric driving wheel 513 rotates around the axis of the second driving wheel 512 and is in sliding fit with the first driven ring 523 in the rotating process, so as to drive the pull rod assembly 52 to move along the axis thereof, and then realize clamping and releasing of the discharge nozzle 433 by the two clamping arms 53. The axis of the second rotary driving member 511, the axis of the second driving wheel 512 and the axis of the first eccentric driving wheel 513 are perpendicular to the axis of the pull rod assembly 52, referring to Figure 1 The second rotary driving member 511 is vertically arranged on the support 3, which reduces the transverse dimension of the support 3 and makes the structure more compact.

[0099] The second rotary driving member 511 can be a rotary motor.

[0100] In other embodiments, the second rotary assembly can also be a linear driving assembly, such as a pneumatic cylinder or an electric push rod, and the telescopic rod directly pushes the pull rod assembly 52 to move.

[0101] Further, the support 3 is provided with a sliding bearing 312, and the pull rod assembly 52 is arranged in the sliding bearing 312, so that the reciprocating movement is more accurate.

[0102] Referring to Figure 9 , the feeding mechanism 6 comprises a third driving assembly 62 and a winding wheel 63, and the base 1 is provided with a feeding platform 121, and the winding wheel 63 is rotatably arranged on the base 1, and the conveying belt 61 is wound on the winding wheel 63, and the conveying belt 61 is led out by the winding wheel 63 and conveyed along the feeding platform 121 under the driving of the third driving assembly 62, so as to realize the transportation of fresh pet food to the feeding area 7 and the transportation of waste food to the waste bin 2.

[0103] Referring to Figure 3 and Figure 9 , the base 1 comprises a lower shell 11 and an upper shelf 12. The mounting cavity 111 is arranged on the lower shell 11, and the upper shelf 12 is buckled on the lower shell 11 and is provided with the feeding platform 121 described above, one side of the feeding platform 121 is provided with a cylindrical first chamber 122, and the other end is provided with a conveying passage 123. Figure 10 The winding wheel 63 is rotatably arranged in the first chamber 122, and the cylindrical first chamber 122 is matched with the winding wheel 63, and the structure is compact. The conveying belt 61 is led out by the winding wheel 63 in the first chamber 122, conveyed on the feeding platform 121, and enters the waste bin 2 through the conveying passage 123 on the other side.

[0104] Referring to Figure 9 , Figure 11 and Figure 12 , the third driving assembly 62 comprises a third rotary driving part 621, a transmission mechanism 622, a driving wheel shaft 623 and a driven wheel 624.

[0105] The third rotary driving part 621 is mounted on the base 1, and specifically mounted on the bottom of the feeding platform 121 of the upper shelf 12. The input end of the transmission mechanism 622 is connected to the output end of the third rotary driving part 621; the driving wheel shaft 623 is rotatably arranged on the upper shelf 12 and is arranged in a spaced manner with the winding wheel 63, and the driving wheel shaft 623 is connected to the output end of the transmission mechanism 622; the driven wheel 624 is rotatably arranged on the upper shelf 12, and the end of the conveying belt 61 away from the winding wheel 63 is clamped between the driving wheel shaft 623 and the driven wheel 624.

[0106] The third rotary driving part 621 drives the driving wheel shaft 623 to rotate through the transmission mechanism 622, and since the conveying belt 61 is clamped between the driving wheel shaft 623 and the driven wheel 624, the driving wheel shaft 623 drives the conveying belt 61 to convey under the action of friction when the driving wheel shaft 623 rotates, realizing the conveying of pet food. The conveying belt 61 is in rolling contact with the driving wheel shaft 623 and the driven wheel 624, avoiding damage to the conveying belt 61.

[0107] The third rotating driving member 621 can be an electric motor. The transmission mechanism 622 can be a synchronous belt transmission mechanism, a driving pulley of which is coaxially connected to an output end of the electric motor, a driven pulley is coaxially arranged on the driving wheel shaft 623, and a synchronous belt of the synchronous belt transmission mechanism is arranged around the driving pulley and the driven pulley. When the electric motor drives the driving pulley to rotate, the driving pulley drives the driven pulley to rotate through the synchronous belt, and power is transmitted to the driving wheel shaft 623.

[0108] Referring to Figure 9 and Figure 11 , the upper frame 12 is provided with a second chamber 124 at an end of the feeding platform 121 away from the first chamber 122, the second chamber 124 is in communication with the conveying channel 123, and the driving wheel shaft 623 is rotatably arranged in the second chamber 124. The second chamber 124 is cylindrical and matches the shape of the driving wheel shaft 623.

[0109] Further, referring to Figure 9 , Figure 10 and Figure 12 , the feeding platform 121 is arc-shaped at an end close to the conveying channel 123 and is connected with the second chamber 124, which facilitates the smooth introduction of the conveying belt 61 between the driving wheel shaft 623 and the driven wheel 624. Two guide members 125 are also arranged in the conveying channel 123, the two guide members 125 are arranged away from the feeding platform 121, and the side of the guide member 125 facing the feeding platform 121 is arc-shaped, which limits and guides the conveying belt 61. Exemplarily, the driven wheel 624 is arranged in two groups, each group includes two driven wheels 624, one of which is rotatably connected to the guide member 125, and the other is rotatably connected to the upper frame 12 and is located below the guide member 125, which ensures that the conveying belt 61 is smoothly conveyed.

[0110] In this embodiment, the driven wheel 624 is connected to the guide member 125 or the upper frame 12 through an elastic member, and is in elastic contact with the conveying belt 61, which avoids damaging the conveying belt 61.

[0111] As shown in Figure 1 and Figure 3 , the base 1 is provided with a cover 13 above the conveying belt 61, and a feeding opening 131 is arranged on the cover 13. The cover 13 is located on one side of the discharging member 43, and an end of the cover 13 away from the discharging member 43 is rotatably arranged on the base 1, specifically rotatably connected to the lower shell 11 through a rotating shaft. The feeding opening 131 is recessed on the cover 13, and when the cover 13 is closed, the gap between the cover 13 and the conveying belt 61 is small or even nonexistent. The pet food cannot enter the feeding area 7 due to being blocked by the wall surface of the feeding opening 131 of the cover 13, and cannot be conveyed from the feeding area 7 to the waste bin 2. Therefore, the cover 13 needs to be turned up and opened to avoid the gap allowing the pet food to pass through when conveying fresh pet food and conveying waste food.

[0112] In this embodiment, referring to Figures 9 to 12 To solve the above problems, the feeding mechanism 6 further comprises a flip cover assembly 64 for realizing the flipping and resetting of the cover 13. The flip cover assembly 64 comprises a driving gear 641, a transmission gear 642, a second eccentric driving wheel 643 and a lifting push rod 644.

[0113] Referring to Figure 11 and Figure 12 The driving gear 641 is connected to the output end of the third rotary driving member 621, the transmission gear 642 is rotatably arranged on the base 1 and is in mesh with the driving gear 641, and the second eccentric driving wheel 643 is eccentrically arranged on the transmission gear 642, i.e. the center of the second eccentric driving wheel 643 is arranged in a spaced-apart manner with the center of the transmission gear 642. The lifting push rod 644 extends vertically and is arranged in a vertically movable manner on the base 1, and a second driven ring 6441 is arranged at the middle part of the lifting push rod 644, and the second eccentric driving wheel 643 is slidably fitted in the second driven ring 6441.

[0114] When the third rotary driving member 621 is started, it drives the transmission gear 642 to rotate through the driving gear 641. When the transmission gear 642 rotates, the second eccentric driving wheel 643 rotates around the center of the transmission gear 642 and slides in the second driven ring 6441, thereby pushing the lifting push rod 644 to ascend or descend. The lifting push rod 644 is used to push the cover 13, so that the cover 13 is flipped upward and opened. When the lifting push rod 644 descends, the cover 13 is buckled on the base 1 under the action of its own gravity, so that the feeding opening 131 and the conveying belt 61 define the feeding area 7 for the pet to eat.

[0115] It can be understood that the third rotary driving member 621 synchronously drives the flipping assembly to move during the driving of the conveying belt 61 to move forward, so as to realize the opening and closing of the cover 13. Further, during the conveying of the conveying belt 61 from below the outflow member 43 to the feeding area 7, the lifting push rod 644 of the flip cover assembly 64 pushes the cover 13 to flip upward and open first, so as to avoid the advancing path of the pet food, and then the lifting push rod 644 descends to close the cover 13, so as to frame the pet food into the feeding opening 131. Similarly, during the conveying of the conveying belt 61 from the feeding area 7 to the waste bin 2, the lifting push rod 644 of the flip cover assembly 64 pushes the cover 13 to flip upward and open first, so as to avoid the advancing path of the waste, and then the lifting push rod 644 descends to close the cover 13, so that the waste food enters the waste bin 2 through the waste inlet 21. This arrangement can reduce the number of driving members, and only one driving member can realize the conveying of the conveying belt 61 and the flipping of the cover 13.

[0116] Further, referring to Figure 9 and Figure 11The transmission gear 642, the second eccentric driving wheel 643 and the lifting push rod 644 are all provided with two, the two transmission gears 642 are connected through a transmission shaft 645 to realize synchronous rotation, and the two lifting push rods 644 are arranged on opposite sides of the upper frame 12 to push the two sides of the material cover 13 to make it turn over and open, thereby ensuring the stability of the turning over and opening and returning of the material cover 13.

[0117] Referring to Figure 2 The pet feeder further comprises a cutting mechanism 8 arranged on the base 1, the cutting mechanism 8 is located above the conveying belt 61 and on the side of the feeding area 7 opposite to the grain outlet member 43, and the cutting mechanism 8 is used to cut the conveying belt 61. When cleaning the waste in the waste bin 2, the conveying belt 61 is cut by the cutting mechanism 8, and the cut conveying belt 61 enters the waste bin 2, so that the user can clean the waste grain and the waste conveying belt 61 in the waste bin 2 synchronously.

[0118] Exemplarily, the cutting mechanism 8 comprises a power mechanism and a cutting knife, the shell of the power mechanism is mounted on the material cover 13, and the cutting knife is mounted on the output end of the power mechanism and is used to lift under the driving of the power mechanism, so that the conveying belt 61 can be cut when the cutting knife is lowered, and the cutting knife returns to the original position after cutting. The power mechanism can be a pneumatic cylinder.

[0119] After the conveying belt 61 is cut, the material cover 13 can be turned over, and the end of the conveying belt 61 is reinserted between the driving shaft 623 and the driven wheel 624. In the embodiment, the conveying belt 61 can be a film, which is easy to cut, and each time the conveying belt 61 conveyed to the feeding area 7 is a new belt wound on the winding wheel 63, which can further ensure the health of the pet.

[0120] Referring to Figure 1 and Figure 3 The lower shell 11 of the base 1 is provided with a pull-out opening 112, and the waste bin 2 enters and exits the mounting cavity 111 through the pull-out opening 112. One of the inner wall of the mounting cavity 111 and the outer wall of the waste bin 2 is provided with a limiting convex strip 22, and the other is provided with a limiting groove 113. The limiting convex strip 22 is arranged in the limiting groove 113, so as to ensure that the waste bin 2 is stable in the mounting cavity 111 and does not shake. The limiting convex strip 22 and the limiting groove 113 extend along the pulling direction of the waste bin 2, so as to guide the waste bin 2 to enter and exit the mounting cavity 111. Furthermore, the limiting convex strip 22 and the limiting groove 113 can position the mounting position of the waste bin 2, so as to ensure that the waste grain inlet 21 of the waste bin 2 can be aligned with the end of the conveying belt 61. Further, a cover that can be opened and closed is arranged at the pull-out opening 112.

[0121] In the embodiment, a plurality of limiting convex strips 22 are arranged at the bottom of the waste bin 2, so as to ensure that the internal space of the waste bin 2 is not reduced. A plurality of limiting grooves 113 corresponding to the plurality of limiting convex strips 22 are arranged at the inner bottom wall of the mounting cavity 111.
