Description

Technical Field

[0001] The present invention relates to the field of energy-saving household appliances, and in particular to an energy-saving household pet food crushing device. Background Art

[0002] Energy-saving household pet food crushing appliances are designed specifically for home use. While meeting the needs of crushing pet food (such as frozen meat, raw bones, fruits, vegetables, grains, etc.), they significantly reduce energy consumption through optimizing motor efficiency, dynamic power regulation, intelligent control and other technical means, while also taking into account ease of operation, safety, and ease of cleaning and maintenance.

[0003] After searching, Chinese patent publication number CN119680685A discloses a bone crusher for processing pet food, comprising a processing box body, one side of the bottom end of the processing box body is fixedly connected to the crushing box, and a slope is provided on the side of the crushing box body close to the processing box body; the staff arranges the crushing assembly inside the crushing box to limit the diffusion of bone powder, and by starting the first cylinder to drive the material blocking plate to rise and fall, the material blocking plate is separated from the discharge port, and the crushed bone powder slides onto the receiving plate through the slope. When the discharged aggregate reaches a certain amount, the first cylinder pushes the material blocking plate down to block the discharge port, the material blocking plate drives the fixed rod to move, the fixed rod drives the rack to move, the rack is engaged with the second gear, so that the second gear rotates, the second gear drives the first rotating rod to rotate, the first rotating rod drives the knocking protrusion to rotate, and the knocking protrusion knocks on the slope, thereby sliding the bone ashes on the slope into the receiving plate, thereby avoiding the accumulation of bone ashes. However, when this scheme is actually used, there are still the following shortcomings: In the daily handling of pet food, many pet owners freeze it to extend its shelf life and maintain its freshness. However, the texture of frozen pet food becomes hard, and when the aforementioned crushing device is used for crushing, it often has difficulty passing through the crushing rollers. To allow these frozen foods to enter the crushing process smoothly, operators often need to use manual pressing to assist in pushing them forward. However, manual pressing has many disadvantages. On the one hand, during the operation, the operator's hands are close to the high-speed crushing rollers, which can easily cause safety accidents such as squeezing and scratching, seriously threatening personal safety. On the other hand, manual pressing not only consumes a lot of physical strength, but also is cumbersome, inefficient, and extremely inconvenient. Summary of the Invention

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] Among them, the drawings are only used for illustrative purposes and represent only schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product.

[0024] The present invention provides a technical solution, referring to Figures 1 to 4 As shown, an energy-saving household pet food crushing device includes a housing 11, a feed housing 12 fixedly mounted on the bottom surface of the housing 11, two crushing rollers 13 symmetrically mounted on the inner wall of the housing 11, and a plurality of evenly distributed crushing teeth 14 provided on the outer wall of the crushing rollers 13. Two transmission gears 15 symmetrically mounted on the side of the housing 11 are fixedly connected to the crushing rollers 13 via a coupling. A drive motor 16 is provided on the side of the housing 11, and the output end of the drive motor 16 is fixedly connected to the side of the transmission gear 15. A sliding frame 31 is slidably mounted on the inner wall of the housing 11. A connecting plate 41 is fixedly mounted on the side edge of the top surface of the sliding frame 31. A winding disk 43 is rotatably mounted on the side of the housing 11. A pull rope 44 is provided on the inner side of the winding disk 43. The pulling end of the pull rope 44 is fixedly connected to the bottom surface of the connecting plate 41. An adjustment structure corresponding to the crushing teeth 14 is provided on the inner side of the crushing roller 13. The adjustment structure includes a plurality of through openings 21 corresponding to the crushing teeth 14 and opened on the outer wall of the crushing roller 13. The crushing teeth 14 are slidably connected to the through openings 21. A pull rod 22 is slidably installed on the inner wall of the crushing roller 13. A plurality of evenly distributed transmission plates 23 are hinged on the outer wall of the pull rod 22. The end of the transmission plate 23 away from the pull rod 22 is hinged to the end of the crushing teeth 14 located on the inner side of the crushing roller 13. An adjustment screw 24 is rotatably installed on the end of the pull rod 22. The end of the adjustment screw 24 away from the pull rod 22 passes through the crushing roller 13 and the casing 11 in sequence. The adjustment screw 24 is respectively screwed to the crushing roller 13 and rotatably connected to the casing 11. The user can take out the device. In the initial state, the position of the cover 32 is as follows: Figure 1 As shown, it is in the vertically open state. The user can power on the device to crush the pet food. Before crushing, the user can adjust the extended length of the crushing teeth 14 on the crushing roller 13 according to the particle size of the pet food to be processed. During adjustment, since the driving motor 16 has a certain self-locking property, it can lock the crushing roller 13 when it is not turned on. The user can directly rotate the adjusting screw 24. The adjusting screw 24 is screwed to the crushing roller 13, so when it rotates, it can move along the through-hole and drive the pull rod 22, so that the pull rod 22 can slide. During the sliding process of the pull rod 22, since a transmission plate 23 is hinged between the pull rod 22 and the crushing teeth 14, the pull rod 22 can push the crushing teeth 14 through the transmission plate 23, so that the crushing teeth 14 can slide along the through opening 21, thereby adjusting the length of the crushing teeth 14 extending out of the through opening 21, so as to crush the food into different particle sizes.

[0025] Reference Figure 2 、 Figure 5 、 Figure 6 As shown, a material pressing assembly is provided on the inner side of the sliding frame 31. The material pressing assembly includes two cover plates 32 symmetrically mounted on the inner wall of the sliding frame 31 via a rotating shaft and a torsion spring. The side of the sliding frame 31 is provided with two arc-shaped openings 33 corresponding to the cover plates 32. The inner wall of the housing 11 is symmetrically provided with two arc-shaped grooves 34 corresponding to the arc-shaped openings 33. The inner wall of the housing 11 is symmetrically provided with two guide grooves 35 respectively connected to the two arc-shaped grooves 34. A guide rod 36 adapted to the arc-shaped opening 33, the arc-shaped groove 34, and the guide groove 35 is fixedly mounted on the side of the cover plate 32. The user can place food in the housing 11. After placing the food, the cover 32 can be rotated so that the cover 32 is rotated from a vertical state to a horizontal state to cover the sliding frame 31. During the rotation, the guide rod 36 on the side of the cover 32 can slide from the arc groove 34 to the guide groove 35 and the guide rod 36 can enter the arc opening 33. Since the guide groove 35 is vertically arranged, the elastic support rod 42 can be compressed when the sliding frame 31 slides downward, and the sliding frame 31 slides downward until the guide rod 36 completely enters the guide groove. When the guide rod 36 enters the guide groove 35, the user can release his hand. When the guide rod 36 completely enters the guide groove 35, the cover plate 32 can be limited so that the cover plate 32 is limited in a horizontal state. When the sliding frame 31 slides downward as a whole, the cover plate 32 is limited in a horizontal state. Therefore, the cover plate 32 can press the food in the casing 11, and when the drive motor 16 is turned on, it can synchronously drive the two transmission gears 15 and the crushing roller 13 to rotate. With the pressure of the cover plate 32 on the food, the food can pass through the crushing roller 13 at a uniform speed and be efficiently crushed.

[0026] Reference Figure 2 、 Figure 7 As shown, a speed regulating assembly is provided between the winding disk 43 and the driving motor 16, and the speed regulating assembly includes two elastic support rods 42 symmetrically fixedly mounted at the side positions of the top surface of the casing 11, and the telescopic ends of the two elastic support rods 42 are fixedly connected to the bottom surface of the connecting plate 41, and a speed regulating roller 45 is rotatably mounted on the side of the casing 11, and a connecting gear 46 is fixedly mounted on the end of the speed regulating roller 45, and a linkage gear 47 meshing with the connecting gear 46 is fixedly mounted on the end of the winding disk 43, and a driving roller 48 corresponding to the speed regulating roller 45 is rotatably mounted on the side of the casing 11, and the speed regulating roller 45 and the driving roller 48 are both configured as frustum, and the driving roller 48 is connected to the output end of the driving motor 16 through a driven wheel and a synchronous belt transmission, and an adjustment mechanism is provided between the speed regulating roller 45 and the driving roller 48; The adjustment mechanism includes a fixed rod 49 fixedly mounted on the side of the housing 11 between the speed regulating roller 45 and the driving roller 48. A speed regulating screw 410 is rotatably mounted on the side of the housing 11 at a position next to the fixed rod 49. An adjustment plate 411 is mounted on the fixed rod 49 and the speed regulating screw 410. A transmission ring 412 is rotatably mounted on the outer wall of the adjustment plate 411. The outer wall of the transmission ring 412 is in contact with the outer walls of the speed regulating roller 45 and the driving roller 48. When the driving motor 16 is turned on, the driving roller 48 can be driven to rotate by the driven wheel and the synchronous belt. When the driving roller 48 rotates, the speed regulating roller 45 can be driven to rotate by the transmission ring 412. The speed regulating roller 45 is engaged with the winding disk 43 through the connecting gear 46 and the linkage gear 47, thereby driving the winding disk 43 to rotate. When the winding disk 43 rotates, the pull rope 44 can be wound, and then the pull plate can be pulled. Before using the device, the user can also adjust the sliding speed of the sliding frame 31 according to the situation of the food. When adjusting, the speed regulating screw 410 can be rotated. The adjusting plate 411 is screwed to the speed regulating screw 410 and is slidably connected to the fixed rod 49, so that the speed regulating roller 45 can rotate. When the speed screw 410 rotates, it can drive the adjustment plate 411 to slide along the fixed rod 49. The driving roller 48 and the speed regulating roller 45 are arranged in opposite directions. Therefore, by adjusting the position of the transmission ring 412 on the adjustment plate 411, the rotation speed of the speed regulating roller 45 and the winding disk 43 can be adjusted, thereby realizing the adjustment of the sliding speed of the sliding frame 31; after the food is crushed, the user can turn on the drive motor 16 again to reverse it, which can drive the winding disk 43 to reverse, and the sliding frame 31 can be reset under the action of the elastic support rod 42. After the sliding frame 31 is reset, the cover plate 32 can be reversed to a vertical state under the action of the torsion spring so that it can be used for feeding again.

[0027] Reference Figure 1 、 Figure 8 、 Figure 9 As shown, a screening assembly is provided on the inner side of the discharge shell 12, and the screening assembly includes a screen plate 51 slidably mounted on the inner wall of the discharge shell 12, an opening 52 corresponding to the screen plate 51 is provided on the side of the discharge shell 12, a support plate 53 is fixedly mounted on the side of the screen plate 51, the support plate 53 passes through the opening 52, and a support spring 54 is fixedly mounted between the inner bottom surface of the opening 52 and the bottom surface of the support plate 53, a cam 55 adapted to the support plate 53 is rotatably mounted on the side of the discharge shell 12, and the cam 55 is connected to the output end of the drive motor 16 through a transmission wheel and a belt transmission, and a discharge port 56 corresponding to the screen plate 51 is provided on the side of the discharge shell 12; The food crushed by the crushing roller 13 can fall onto the sieve plate 51 under the action of gravity. When the driving motor 16 is running, the cam 55 can be synchronously driven to rotate by the transmission wheel and the belt. The cam 55 is in contact with the top surface of the support plate 53, and then during the rotation, the support plate 53 and the sieve plate 51 can be used in conjunction with the support spring 54 to slide back and forth along the opening 52, so that the sieve plate 51 can vibrate. The sieve plate 51 can screen the crushed food during the vibration process and screen out the food with smaller particle size. At the same time, for frozen food, the crushed ice residue and moisture can be screened out so that the crushed food can be processed later. Since the sieve plate 51 is set at an angle, the screened food can be discharged through the discharge port 56.

[0028] Reference Figure 2 、 Figure 9 As shown, a material guide assembly corresponding to the screening assembly is provided on the inner side of the discharge shell 12, and the material guide assembly includes two support rollers 61 rotatably mounted on the inner wall of the discharge shell 12, and a conveyor belt 62 is sleeved on the two support rollers 61, and a plurality of baffles 63 distributed at equal intervals are fixedly mounted on the conveyor belt 62, and the top surface of the baffle 63 is provided with hard bristles, and a bracket 64 is fixedly mounted on the side of the support plate 53, and a drive rack 65 is fixedly mounted on the end of the bracket 64. A one-way bearing 66 is rotatably mounted on the side of the discharge shell 12 through a rotating rod, and the end of the rotating rod is fixedly connected to the support rollers 61, and a set gear 67 meshing with the drive rack 65 is fixedly sleeved on the outer wall of the one-way bearing 66, and a pull-out box 68 corresponding to the conveyor belt 62 and the baffle 63 is provided at the end of the discharge shell 12 away from the discharge port 56; The food, ice debris and water with smaller particle size can pass through the sieve plate 51 and enter between the baffles 63 on the conveyor belt 62. During the reciprocating movement of the support plate 53, the driving rack 65 can be driven by the bracket 64 to slide back and forth. During the downward sliding of the driving rack 65, the set gear 67 can be driven to rotate. This direction is the locking direction of the one-way bearing 66, so it can drive the support roller 61 to rotate. When the driving rack 65 slides upward, the rotation direction of the set gear 67 is the free direction of the one-way bearing 66, so it cannot drive the support roller 61 to rotate. The rotation of the support roller 61 can drive the conveyor belt 62 to rotate in the opposite direction of the movement of the food along the sieve plate 51, and during the movement of the baffle 63, the sieve plate 51 can be cleaned by the hard bristles on the top surface to reduce the occurrence of blockage. As the conveyor belt 62 is transported, food, ice debris and water with smaller particle size can enter the pull-out box 68 under the action of gravity for collection.

[0029] Working principle of the present invention: When in use, the user can take out the device. In the initial state, the position of the cover 32 is as follows: Figure 1 As shown, it is in a vertically open state. The user can power on the device to perform the crushing operation on the pet food. Before crushing, the user can adjust the protruding length of the crushing teeth 14 on the crushing roller 13 according to the particle size of the pet food to be processed. During adjustment, since the driving motor 16 has a certain self-locking property, the crushing roller 13 can be locked when it is not turned on. The user can directly rotate the adjusting screw 24. The adjusting screw 24 is screwed to the crushing roller 13. Therefore, when it rotates, it can move along the penetration and drive the pull rod 22 to enable the pull rod 22 to slide. During the sliding process of the pull rod 22, since a transmission plate 23 is hinged between the pull rod 22 and the crushing teeth 14, the pull rod 22 can push the crushing teeth 14 through the transmission plate 23, so that the crushing teeth 14 can slide along the through opening 21, thereby adjusting the length of the crushing teeth 14 extending from the through opening 21, so as to crush the food into different particle sizes. When crushing food, especially frozen food, the user can place the food in the casing 11. After placing the food, the cover plate 32 can be rotated so that the cover plate 32 is rotated from a vertical state to a horizontal state to cover the sliding frame 31. During the rotation, the guide rod 36 on the side of the cover plate 32 can slide from the arc groove 34 to the guide groove 35 and the guide rod 36 can enter the arc mouth 33. Since the guide groove 35 is vertically arranged, when the drive motor 16 is turned on, it can drive the drive roller 48 to rotate through the driven wheel and the synchronous belt. When the drive roller 48 rotates, it can drive the speed regulating roller 45 to rotate through the transmission ring 412. The speed regulating roller 45 is engaged with the winding disk 43 through the connecting gear 46 and the linkage gear 47, thereby driving the winding disk 43 to rotate. When the reel 43 rotates, the pull rope 44 can be reeled in, and then the pull plate can be pulled, so that the sliding frame 31 slides downward and compresses the elastic support rod 42. When the sliding frame 31 slides downward, the guide rod 36 completely enters the guide groove 35, and the user can release his hand. When the guide rod 36 completely enters the guide groove 35, the cover plate 32 can be limited, so that the cover plate 32 is limited in a horizontal state. When the sliding frame 31 slides downward as a whole, the cover plate 32 is limited in a horizontal state, so the cover plate 32 can press the food in the casing 11. When the drive motor 16 is turned on, it can synchronously drive the two transmission gears 15 and the crushing roller 13 to rotate. With the cover plate 32 pressing the food, the food can pass through the crushing roller 13 at a uniform speed and be efficiently crushed. Before using the device, the user can also adjust the sliding speed of the sliding frame 31 according to the condition of the food. When adjusting, the speed regulating screw 410 can be rotated. The adjusting plate 411 is screwed to the speed regulating screw 410 and is slidably connected to the fixed rod 49. Therefore, when the speed regulating screw 410 rotates, it can drive the adjusting plate 411 to slide along the fixed rod 49. The driving roller 48 and the speed regulating roller 45 are arranged oppositely. Therefore, by adjusting the position of the transmission ring 412 on the adjusting plate 411, the rotation speed of the speed regulating roller 45 and the winding disk 43 can be adjusted, thereby realizing the adjustment of the sliding speed of the sliding frame 31. The food crushed by the crushing roller 13 can fall onto the sieve plate 51 under the action of gravity. When the driving motor 16 is running, the cam 55 can be driven to rotate synchronously by the transmission wheel and the belt. The cam 55 is in contact with the top surface of the support plate 53, and then the support plate 53 and the sieve plate 51 can be used to slide back and forth along the opening 52 in cooperation with the support spring 54 during the rotation process, so that the sieve plate 51 can vibrate. The sieve plate 51 can screen the crushed food during the vibration process and screen out the food with smaller particle size. At the same time, for frozen food, the crushed ice residue and moisture can be screened out so that the crushed food can be processed later. The screened food can be discharged through the discharge port 56 because the sieve plate 51 is tilted. The food with smaller particle size, ice residue and moisture can pass through the sieve plate 51 and enter between the baffles 63 on the conveyor belt 62. During the reciprocating movement of the support plate 53, the rack 65 can be driven to slide back and forth by the bracket 64. The gear 67 is locked and the roller 61 is driven to rotate. When the rack 65 is driven, the gear 67 rotates in the free direction of the one-way bearing 66, so the roller 61 cannot be driven to rotate. The rotation of the roller 61 can drive the conveyor belt 62 to rotate in the opposite direction of the movement of the food along the sieve plate 51, and the sieve plate 51 can be cleaned by the hard bristles on the top surface during the movement of the baffle 63, thereby reducing the occurrence of blockage. As the conveyor belt 62 is transported, food with smaller particle size, ice debris and water can enter the pull-out box 68 under the action of gravity and be collected. After the food is crushed, the user can start the drive motor 16 again to reverse it, which can drive the winding disk 43 to reverse. The sliding frame 31 can be reset under the action of the elastic support rod 42, and after the sliding frame 31 is reset, the cover plate 32 can be reversed to a vertical state under the action of the torsion spring so that it can be used for feeding again.
