Description

Technical Field

[0001] This invention relates to the field of energy-saving household appliances, specifically to an energy-saving household pet food crushing device. Background Technology

[0002] Energy-saving household pet food shredders are household appliances designed specifically for home use. They meet the needs of shredding pet food (such as frozen meat, raw bones, fruits, vegetables, grains, etc.) while significantly reducing energy consumption through technologies such as optimized motor efficiency, dynamic power adjustment, and intelligent control. They also offer ease of operation, safety, and convenient cleaning and maintenance.

[0003] A search revealed Chinese patent CN119680685A, which discloses a bone crusher for pet food processing. The crusher includes a processing chamber with a grinding chamber fixedly connected to one side of its bottom. An inclined ramp is located inside the grinding chamber near the processing chamber. The crushing components are placed inside the grinding chamber to limit the spread of bone powder. A first cylinder is activated, causing a baffle plate to rise and fall, separating it from the discharge port. The crushed bone powder slides onto a receiving plate via the ramp. When a certain amount of bone powder is discharged, the first cylinder pushes the baffle plate downwards to block the discharge port. The baffle plate moves a fixed rod, which in turn moves a rack. The rack meshes with a second gear, causing the second gear to rotate. The second gear then rotates a first rotating rod, which in turn rotates a striking protrusion. The striking protrusion strikes the ramp, causing the bone ash on the ramp to slide onto the receiving plate, thus preventing bone ash accumulation. However, this design still has the following shortcomings in practical use: In the daily handling of pet food, many pet owners freeze it to extend its shelf life and maintain its freshness. However, frozen pet food becomes hard and often struggles to pass smoothly through the crushing rollers when processed by the aforementioned crushing device. To get these frozen foods into the crushing process smoothly, operators often need to manually press them forward. However, manual pressing has many drawbacks. On the one hand, during operation, the operator's hands are close to the high-speed rotating crushing rollers, which can easily lead to crushing, scratches, and other safety accidents, seriously threatening personal safety. On the other hand, manual pressing is not only physically demanding but also cumbersome, inefficient, and extremely inconvenient. Summary of the Invention

[0009] Furthermore, the speed control assembly includes two elastic support rods symmetrically fixedly installed on the side of the top surface of the housing, and the telescopic ends of the two elastic support rods are fixedly connected to the bottom surface of the connecting plate. A speed control roller is rotatably installed on the side of the housing, and a connecting gear is fixedly installed at the end of the speed control roller. A linkage gear that meshes with the connecting gear is fixedly installed at the end of the take-up reel. A drive roller corresponding to the speed control roller is rotatably installed on the side of the housing, and the drive roller is connected to the output end of the drive motor through a driven wheel and a synchronous belt.

[0015] The beneficial effects of this invention are: 1. This invention uses a pull rod and an adjusting screw to lock the crushing roller through the self-locking characteristic of the drive motor. Rotating the adjusting screw drives the pull rod, and the extension length of the crushing teeth can be flexibly changed through the transmission plate, thus achieving precise control of the particle size of pet food. This design does not require complicated operation or additional power, meets the processing needs of different pet food, and improves the versatility and ease of use of the device.

[0016] 2. This invention, by setting up a take-up reel, connecting plate, and linkage between the cover plate and sliding frame, and driving the components to operate, causes the sliding frame to slide down, causing the cover plate to automatically press the food. In conjunction with the rotating crushing roller, it ensures that hard foods such as frozen foods pass through the crushing roller at a uniform speed. This process does not require manual pressing, which avoids safety hazards and improves crushing efficiency, realizing automated and efficient food crushing operation.

[0017] 3. By setting up speed-regulating rollers and drive rollers, the drive motor drives the cam to rotate during operation, which, together with the support spring, causes the screen plate to vibrate back and forth. This not only effectively screens crushed food and separates small-sized food particles, ice crystals, and moisture, but also allows for targeted processing of frozen food. At the same time, the inclined screen plate design facilitates food discharge, providing convenience for subsequent processing and ensuring screening effect and processing efficiency.

[0018] 4. This invention utilizes baffles and one-way bearings, with the reciprocating movement of the support plate driving the sliding of the drive rack. The one-way bearings drive the rotation of the support rollers, causing the conveyor belt to operate. The baffles on the conveyor belt, in conjunction with hard bristles, clean the screen plate to prevent clogging. Simultaneously, the small-sized food particles, ice crystals, and moisture after screening are collected in a pull-out box. After crushing, the motor reverses to automatically reset the device. The entire process is continuous and orderly, reducing manual intervention and improving processing efficiency and the degree of automation of the device. Attached Figure Description

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

[0023] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0024] This 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 feeding shell 12 fixedly installed on the bottom surface of the housing 11, two crushing rollers 13 symmetrically rotated and installed on the inner wall of the housing 11, a number of evenly distributed crushing teeth 14 are provided on the outer wall of the crushing rollers 13, two transmission gears 15 symmetrically rotated and installed on the side of the housing 11, and the transmission gears 15 are fixedly connected to the crushing rollers 13 by a coupling shaft, and 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 gears 15. A sliding frame 31 is slidably installed on the inner wall of the housing 11. A connecting plate 41 is fixedly installed on the top side of the sliding frame 31. A take-up reel 43 is rotatably installed on the side of the housing 11. A pull rope 44 is provided on the inner side of the take-up reel 43. The pulling end of the pull rope 44 is fixedly connected to the bottom surface of the connecting plate 41. The inner side of the crushing roller 13 is provided with an adjustment structure corresponding to the crushing teeth 14. The adjustment structure includes several openings 21 on the outer wall of the crushing roller 13 corresponding to the crushing teeth 14. The crushing teeth 14 are slidably connected to the openings 21. A pull rod 22 is slidably installed on the inner wall of the crushing roller 13. Several evenly distributed transmission plates 23 are hinged to 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 at 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 housing 11 in sequence. The adjustment screw 24 is screwed to the crushing roller 13 and rotatably connected to the housing 11. The user can remove the device. In its initial state, the cover plate 32 is positioned as follows: Figure 1 As shown, the device is in its vertically open state. Users can power on the device to crush pet food. Before crushing, users can adjust the extension 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, the drive motor 16 has a self-locking property, locking the crushing roller 13 when not in operation. Users can directly rotate the adjusting screw 24, which is screwed onto the crushing roller 13. Therefore, its rotation moves along the through-hole and drives the pull rod 22, allowing it to slide. During the sliding process, 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, allowing the crushing teeth 14 to slide along the opening 21, thus adjusting the extension length of the crushing teeth 14 beyond the opening 21 to crush the food into different particle sizes.

[0025] Reference Figure 2 , Figure 5 , Figure 6 As shown, a pressing assembly is provided on the inner side of the sliding frame 31. The pressing assembly includes two cover plates 32 that are symmetrically rotated and installed on the inner wall of the sliding frame 31 via a rotating shaft and a torsion spring. Two arc-shaped openings 33 corresponding to the cover plates 32 are opened on the side of the sliding frame 31. Two arc-shaped grooves 34 corresponding to the arc-shaped openings 33 are symmetrically opened on the inner wall of the housing 11. Two guide grooves 35 that communicate with the two arc-shaped grooves 34 are symmetrically opened on the inner wall of the housing 11. A guide rod 36 that is adapted to the arc-shaped openings 33, arc-shaped grooves 34, and guide grooves 35 is fixedly installed on the side of the cover plate 32. The user can place food in the housing 11. After placement, the cover 32 can be rotated from a vertical to a horizontal position, covering 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 into the guide groove 35 and enter the arc opening 33. Since the guide groove 35 is vertically set, the sliding frame 31 can compress the elastic support rod 42 when it slides downward. The sliding frame 31 slides downward until the guide rod 36 is fully inserted into the guide groove 35. When the guide rod 36 is fully inserted into the guide groove 35, the user can release his hand. When the guide rod 36 is fully inserted into the guide groove 35, it can limit the cover plate 32, so that the cover plate 32 is limited to a horizontal state. When the sliding frame 31 slides down as a whole, the cover plate 32 can press the food in the housing 11 because it is limited to a horizontal state. 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 pressing of the food by the cover plate 32, 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 component is provided between the take-up reel 43 and the drive motor 16. The speed regulating component includes two elastic support rods 42 symmetrically fixedly installed on the side of the top surface of the housing 11, and the telescopic ends of the two elastic support rods 42 are fixedly connected to the bottom surface of the connecting plate 41. A speed regulating roller 45 is rotatably installed on the side of the housing 11, and a connecting gear 46 is fixedly installed at the end of the speed regulating roller 45. A linkage gear 47 that meshes with the connecting gear 46 is fixedly installed at the end of the take-up reel 43. A drive roller 48 corresponding to the speed regulating roller 45 is rotatably installed on the side of the housing 11. Both the speed regulating roller 45 and the drive roller 48 are frustum-shaped, and the drive roller 48 is connected to the output end of the drive motor 16 through a driven wheel and a synchronous belt. An adjustment mechanism is provided between the speed regulating roller 45 and the drive roller 48. The adjustment mechanism includes a fixed rod 49 fixedly installed on the side of the housing 11 between the speed regulating roller 45 and the drive roller 48. A speed regulating screw 410 is rotatably installed on the side of the housing 11 at the side position of the fixed rod 49. An adjustment plate 411 is fitted on the fixed rod 49 and the speed regulating screw 410. A transmission ring 412 is rotatably fitted 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 drive roller 48. When the drive motor 16 is turned on, it drives the drive roller 48 to rotate via the driven wheel and synchronous belt. The rotation of the drive roller 48 drives the speed regulating roller 45 to rotate via the transmission ring 412. The speed regulating roller 45 meshes with the take-up reel 43 via a connecting gear 46 and a linkage gear 47, thereby driving the take-up reel 43 to rotate. The rotation of the take-up reel 43 winds up the pull rope 44, which in turn pulls the pull plate. Before using the device, the user can also adjust the sliding speed of the sliding frame 31 according to the food. Adjustment is achieved by rotating the speed regulating screw 410. The adjusting plate 411 is screwed to the speed regulating screw 410 and slidably connected to the fixed rod 49. When the speed screw 410 rotates, it can drive the adjusting plate 411 to slide along the fixed rod 49. The drive 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 adjusting plate 411, the rotation speed of the speed regulating roller 45 and the take-up reel 43 can be adjusted, thereby realizing the adjustment of the downward 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 will drive the take-up reel 43 to reverse. Under the action of the elastic support rod 42, the sliding frame 31 can be reset. After the sliding frame 31 is reset, under the action of the torsion spring, the cover plate 32 can be reversed to a vertical state for feeding again.

[0027] Reference Figure 1 , Figure 8 , Figure 9 As shown, a screening assembly is provided on the inner side of the feeding shell 12. The screening assembly includes a screen plate 51 that is slidably installed on the inner wall of the feeding shell 12. An opening 52 corresponding to the screen plate 51 is opened on the side of the feeding shell 12. A support plate 53 is fixedly installed on the side of the screen plate 51. The support plate 53 passes through the opening 52, and a support spring 54 is fixedly installed 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 installed on the side of the feeding shell 12. The cam 55 is connected to the output end of the drive motor 16 through a transmission wheel and a belt. A feeding port 56 corresponding to the screen plate 51 is opened on the side of the feeding shell 12. The food crushed by the crushing roller 13 falls onto the screen plate 51 under gravity. When the drive motor 16 runs, it can drive the cam 55 to rotate synchronously through the transmission wheel and belt. The cam 55 is in contact with the top surface of the support plate 53. In the process of rotation, with the use of the support spring 54, the support plate 53 and the screen plate 51 can slide back and forth along the opening 52, thereby making the screen plate 51 vibrate. During the vibration, the screen plate 51 can screen the crushed food, separating out the food with smaller particle size. At the same time, for frozen food, it can separate out the ice and water after crushing, so as to facilitate the subsequent processing of the crushed food. The food after screening can be discharged through the feed port 56 because the screen plate 51 is set at an inclination.

[0028] Reference Figure 2 , Figure 9 As shown, the inner side of the discharge shell 12 is provided with a guiding component corresponding to the screening component. The guiding component includes two support rollers 61 rotatably mounted on the inner wall of the discharge shell 12. A conveyor belt 62 is fitted on the two support rollers 61. Several baffles 63 distributed at equal intervals are fixedly installed on the conveyor belt 62. The top surface of the baffles 63 is provided with hard bristles. A bracket 64 is fixedly installed on the side of the support plate 63. A drive rack 65 is fixedly installed at 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. The end of the rotating rod is fixedly connected to the support roller 61. A gear 67 that meshes with the drive rack 65 is fixedly fitted on the outer wall of the one-way bearing 66. A pull-out box 68 corresponding to the conveyor belt 62 and the baffles 63 is provided at the end of the discharge shell 12 away from the discharge port 56. Smaller particles of food, ice, and moisture can pass through the sieve plate 51 and enter the space between the baffles 63 on the conveyor belt 62. During the reciprocating movement of the support plate 53, the drive rack 65 can be driven to slide back and forth through the bracket 64. When the drive rack 65 slides downward, it can drive the set gear 67 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 drive 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 food moving along the sieve plate 51. During the movement of the baffles 63, the hard bristles on the top surface can clean the sieve plate 51, reducing the occurrence of blockages. As the conveyor belt 62 conveys, smaller particles of food, ice, and moisture can enter the pull-out box 68 for collection under the action of gravity.

[0029] Working principle of the invention: In use, the user can remove the device. In the initial state, the position of the cover plate 32 is as follows: Figure 1 As shown, this is the vertically open state. The user can power on the device to crush pet food. Before crushing, the user can adjust the extension 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, the drive motor 16 has a certain self-locking property, so it can lock the crushing roller 13 when it is not open. 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 the 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-hole 21, thereby adjusting the length of the crushing teeth 14 extending out of the through-hole 21, so as to crush the food into different particle sizes. During specific crushing operations, especially for frozen foods, the user can place the food in the casing 11. After placement, the cover plate 32 can be rotated from a vertical to a horizontal position, covering the sliding frame 31. During rotation, the guide rod 36 on the side of the cover plate 32 can slide from the arc-shaped groove 34 into the guide groove 35 and enter the arc-shaped opening 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 and the take-up reel 43 are connected by the connecting gear 46 and the linkage gear 47, which can drive the take-up reel 43 to rotate. When the reel 43 rotates, it can wind up the pull rope 44, which in turn can pull the pull plate, causing the sliding frame 31 to slide downward and compress the elastic support rod 42. When the sliding frame 31 slides downward, the user can release their hand when the guide rod 36 is fully inserted into the guide groove 35. When the guide rod 36 is fully inserted into the guide groove 35, it can limit the cover plate 32, so that the cover plate 32 is limited to a horizontal state. When the sliding frame 31 slides downward as a whole, the cover plate 32 can press the food in the machine casing 11 because it is limited to a horizontal state. 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 pressing of the food by the cover plate 32, 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 food. During adjustment, the speed adjustment screw 410 can be rotated. The adjustment plate 411 is screwed to the speed adjustment screw 410 and slidably connected to the fixed rod 49. Therefore, when the speed adjustment screw 410 rotates, it can drive the adjustment plate 411 to slide along the fixed rod 49. The drive roller 48 and the speed adjustment roller 45 are arranged oppositely. Therefore, by adjusting the position of the transmission ring 412 on the adjustment plate 411, the rotation speed of the speed adjustment roller 45 and the take-up reel 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 falls onto the screen plate 51 under gravity. When the drive motor 16 runs, it drives the cam 55 to rotate synchronously through the transmission wheel and belt. The cam 55 is in contact with the top surface of the support plate 53. During the rotation, in conjunction with the use of the support spring 54, the support plate 53 and the screen plate 51 can slide back and forth along the opening 52, thereby causing the screen plate 51 to vibrate. During the vibration, the screen plate 51 can screen the crushed food, separating out food with smaller particle sizes. For frozen food, it can also separate out the crushed ice and water for subsequent processing. The screened food, due to the inclined setting of the screen plate 51, can be discharged through the discharge port 56. Food with smaller particle sizes, ice, and water can pass through the screen plate 51 and enter the baffles 63 on the conveyor belt 62. During the reciprocating movement of the support plate 53, the drive rack 65 can slide back and forth through the bracket 64. During the downward sliding of the drive rack 65... The gear set 67 can be rotated in the direction that is the locking direction of the one-way bearing 66, thus driving the support roller 61 to rotate. However, when the drive rack 65 slides upward, the rotation direction of the gear set 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 to the movement of the food along the screen plate 51. During the movement of the baffle 63, the hard bristles on the top surface can clean the screen plate 51, reducing the occurrence of blockages. As the conveyor belt 62 conveys, smaller particles of food, ice crystals, and moisture can enter the pull-out box 68 for collection under the action of gravity. After the food is crushed, the user can turn on the drive motor 16 again to reverse it, which will drive the reel 43 to reverse. Under the action of the elastic support rod 42, the sliding frame 31 can be reset.
