Description

Technical Field

[0001] This utility model relates to the field of feeder technology, and more specifically, to a feeder. Background Technology

[0002] Pet feeders have become a common item in pet care. They are devices that can automatically or manually provide food to pets and small animals. Through a specific structure, they can store, distribute, and release food in a measured amount, helping users ensure that the pet receives an appropriate amount of food when they are unable to care for it. They are widely used in family pet feeding, small-scale breeding, and other scenarios, and can effectively ensure the healthy growth of pets.

[0003] However, existing feeders have the following problems when in use:

[0004] Currently, for families with multiple types of pets, existing feeders require additional feeders of each type to avoid competition for food, which obviously increases costs and takes up too much space. In addition, existing feeders cannot meet the pets' needs for different types of food, and some feeders have simple dispensing structures that are prone to impeller rotation due to the weight and vibration of the material, resulting in mis-dispensing and low control accuracy.

[0005] This invention enables precise feeding control, prevents accidental material discharge through multiple structural combinations, and can provide single-sided or alternating feeding to meet diverse needs, thereby improving reliability and practicality. Utility Model Content

[0006] The present invention aims to solve the technical problems mentioned in the background art and provide a feeder.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a feeder, comprising: a base, a motor fixedly mounted on the middle of the left end of the base, and latches slidably mounted on both sides of the front of the base; characterized in that: a shell is detachably connected to the front of the base, and slots are provided on both the left side of the front of the base and the right side inside the shell, with two latches embedded in the slots; a return spring is fixedly connected to the outer end face of each latch, and a locking tooth is fixedly mounted on the other end of each latch, with the locking teeth facing opposite directions; and the motor output shaft... A left and right material distributing impeller are rotatably mounted, both housed within a base. Limiting wheels are nested on the surfaces of both impellers, with equidistant limiting teeth fixedly mounted around their outer ends. These teeth are triangular in shape, and their orientations are opposite. The locking teeth engage with the limiting teeth. A return spring on the left-side latch is fixedly connected to a slot on the base, and a fixing seat is fixedly connected to the right side of the right-side latch, with the left end of the fixing seat fixedly connected to the return spring.

[0008] A further preferred embodiment: both the base and the middle of the outer shell are fixedly installed with partitions, and each partition has an arc-shaped hole I on its opposite side. Arc-shaped holes II and III are respectively opened on the left and right sides of the back of the outer shell, and arc-shaped holes I, II and III are all semi-circular.

[0009] A further preferred embodiment: A support ring is fixedly installed on the left side of the front of the base, the arc-shaped hole three is adapted to the outer periphery of the support ring, the motor is fixedly installed on the left end of the support ring, a through hole is opened in the middle of the support ring, and limit holes are opened in the right end of the base and the arc-shaped hole two, and the two limit holes are combined to form a complete limit hole.

[0010] A further preferred embodiment: the support ring has slots on its front side and the right side of the inner shell, and the slots are adapted to the buckles.

[0011] A further preferred embodiment: a rotating shaft is fixedly installed at the output end of the motor, and a left and right material distribution impellers are rotatably connected to the surface of the rotating shaft. A limiting wheel nested on the outer surface of the left and right material distribution impellers has a nested cavity inside, and the nested cavity fits into the surface of the left and right material distribution impellers.

[0012] A further preferred embodiment: the surface of the limiting wheel is provided with a number of limiting grooves, the number of limiting grooves being consistent with the number of blades on the surfaces of the left and right distributing impellers, and the blades being embedded in the limiting grooves.

[0013] A further preferred embodiment: the fixing base is fixedly installed on the right end of the housing and located on the right side of the slot.

[0014] Beneficial effects:

[0015] 1. By setting limit wheels, limit teeth, and locking teeth, the limit wheels move synchronously with the distributing impeller. The limit teeth and locking teeth are complementary in shape and opposite in direction, which can form a mechanical lock when the motor stops. The mechanical limit of the inclined plane and right angle prevents the distributing impeller from rotating due to external force, avoiding accidental material discharge and ensuring accurate quantity control. At the same time, the two work together to drive the left and right distributing impellers to unlock when the motor rotates forward and reverse, realizing single-sided distributing, which can meet the needs of distinguishing materials and controlling the amount of feed. The device will also emit a prompt sound when distributing materials, improving the user experience. It can also reliably engage when resetting, ensuring stable operation of the device.

[0016] 2. Equipped with a latch and a return spring, the latch and return spring work together to be pressed outward by the inclined surface of the limiting teeth when the material dispensing impeller rotates. The compression of the spring unlocks the impeller, ensuring smooth material feeding. After the motor stops, the spring force pushes the latch back, causing the locking teeth to precisely engage with the limiting teeth, forming a reliable lock to prevent the impeller from rotating on its own. The left and right latches are independently driven by springs in the base and outer shell, respectively, and can lock the corresponding impellers individually. With the forward and reverse rotation of the motor, single-sided or alternating material dispensing can be achieved. At the same time, the elastic force provided by the spring makes the latch easy to install and remove, taking into account the stability of the device connection and the convenience of maintenance, thus improving the overall reliability of operation.

[0017] 3. In summary, this type of feeder, through its structure including a dispensing impeller, a limiting wheel, limiting teeth, a latch, a return spring, and locking teeth, achieves efficient and precise feeding control. The dispensing impeller is responsible for pushing the material, while the limiting wheel is rigidly synchronized with the impeller through a nested cavity and a limiting groove, ensuring consistent movement. The complementary reverse design of the limiting teeth and locking teeth, combined with the latch driven by the return spring, unlocks through inclined surface compression when the motor is running, ensuring smooth material feeding by the impeller. After stopping, they tightly engage to form a mechanical lock, preventing accidental material discharge through a dual anti-rotation mechanism. The left and right structures operate independently, and with the forward and reverse rotation of the motor, single-sided dispensing can be achieved, meeting diverse feeding needs and significantly improving the overall reliability and practicality of the operation.

[0025] The following will refer to the appendix in the embodiments of this utility model. Figures 1-6 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0026] Please see Figure 1-6In this embodiment of the utility model, a feeder includes: a base 1, a motor 2 fixedly mounted on the middle of the left end of the base 1, and buckles 3 slidably mounted on both the left and right sides of the front of the base 1. The base 1 is characterized by having a detachable outer shell 101 connected to its front. Slots 109 are provided on both the left side of the front of the base 1 and the right side inside the outer shell 101. Two buckles 3 are embedded in the slots 109. Each buckle 3 has a return spring 301 fixedly connected to its outer end and a tooth 302 fixedly mounted on its other end, with the teeth 302 facing opposite directions. A left dispensing impeller 202 and a right dispensing impeller 203 are rotatably mounted on the output shaft of the motor 2, and both the left and right dispensing impellers are housed inside the base 1. Limiting wheels 204 are nested on the surfaces of impeller 202 and right distribution impeller 203. Limiting teeth 206 are fixedly installed at equal intervals around the outer ends of the limiting wheels 204. The limiting teeth 206 are triangular in shape, and the limiting teeth 206 at the outer ends of the two limiting wheels 204 face opposite directions. The locking teeth 302 and the limiting teeth 206 cooperate with each other. The return spring 301 on the left buckle 3 is fixedly connected to the slot 109 on the base 1. The right buckle 3 is fixedly connected to the right side of the fixing seat 303, and the left end of the fixing seat 303 is fixedly connected to the return spring 301. The base 1 and the middle of the outer shell 101 are both fixedly installed with partition plates 102. The opposite sides of the partition plates 102 are provided with arc-shaped holes 103. The left and right sides of the back of the outer shell 101 are respectively provided with arc-shaped holes 102. 4. Arc-shaped hole 105, arc-shaped hole 103, arc-shaped hole 2 104, and arc-shaped hole 3 105 are all semi-circular. A support ring 106 is fixedly installed on the left side of the front of the base 1. Arc-shaped hole 3 105 is adapted to the outer periphery of the support ring 106. The motor 2 is fixedly installed on the left end of the support ring 106. A through hole 107 is opened in the middle of the support ring 106. Limiting holes 108 are opened in the right end of the base 1 and the inside of arc-shaped hole 2 104. The two limiting holes 108 are combined to form a complete limiting hole 108. A slot 109 is opened on the front of the support ring 106 and the right side of the inside of the outer shell 101. The slot 109 is adapted to the buckle 3. The partition 102 of the base 1 and the outer shell 101 are combined to form two independent material chambers, corresponding to the left material distribution impeller 202 and the right material distribution impeller, respectively. In the working area of ​​impeller 203, materials such as pet food and feed are loaded into the left and right material chambers. The materials fall into the gaps of the distributing impellers. When feeding is needed, motor 2 is powered on and its output shaft drives the left and right distributing impellers 202 and 203 to rotate. When the distributing impellers rotate, the limiting wheel 204 nested on the surface rotates synchronously with them, and the triangular three-dimensional limiting tooth 206 at the outer end rotates accordingly. At this time, the locking tooth 302 of the latch 3 is movably connected to the limiting tooth 206. Because the limiting tooth 206 is three-dimensional triangular, its inclined surface rises from low to high. When the distributing impellers rotate, the limiting tooth 206 contacts the locking tooth 302 in sequence. As the limiting tooth 206 moves, the locking tooth 302 reciprocates from low to high, thus producing a clicking sound.When motor 2 stops working, the distributing impeller loses its driving force. At this time, the locking teeth 302 of the latch 3 and the limiting teeth 206 of the limiting wheel 204 automatically engage due to their structural compatibility. The locking teeth 302 and the limiting teeth 206 face opposite directions and have complementary shapes, forming a mechanical lock. The triangular three-dimensional limiting teeth 206 and the locking teeth 302 are locked together. Utilizing the mechanical limiting effect of the inclined plane and right angle, the distributing impeller is prevented from rotating due to external forces such as material gravity and vibration, ensuring that the material does not rotate accidentally when the motor is not working. The material is discharged externally to control the amount of feed. When feeding is needed again, motor 2 restarts, and the driving force of the output shaft drives the distributing impeller and the limiting wheel to rotate, causing the limiting tooth 206 to disengage from the locking tooth 302. Because the limiting tooth 206 faces opposite directions, the forward and reverse rotation of the motor can respectively drive one of the left distributing impeller 202 or the right distributing impeller 203 to unlock, repeating the distributing process. After completion, the locking tooth 302 and the limiting tooth 206 are locked again to prevent rotation and avoid accidental discharge caused by external force.

[0027] In this embodiment of the invention, a rotating shaft 201 is fixedly installed at the output end of the motor 2. A left distributing impeller 202 and a right distributing impeller 203 are rotatably connected to the surface of the rotating shaft 201. A limiting wheel 204 nested on the outer surface of the left distributing impeller 202 and the right distributing impeller 203 has a nested cavity 205 inside. The nested cavity 205 fits against the surface of the left distributing impeller 202 and the right distributing impeller 203. A plurality of limiting grooves 207 are formed on the surface of the limiting wheel 204. The number of limiting grooves 207 is consistent with the number of blades on the surface of the left distributing impeller 202 and the right distributing impeller 203, and the blades are embedded in the limiting grooves 207. The limiting wheel 204 nested on the outer surface of the left and right material distribution impellers 202 and 203 has an internal nesting cavity 205 that is tightly fitted with the surfaces of the left and right material distribution impellers 202 and 203. The limiting groove 207 on the surface of the limiting wheel 204 is in close contact with the blades of the left and right material distribution impellers 202 and 203, and the blades are embedded in the limiting groove, further strengthening the synchronous movement relationship between the limiting wheel 204 and the impellers. When the impellers rotate, the limiting wheel must rotate synchronously; conversely, when the limiting wheel is locked, the impeller cannot rotate. If the motor rotates forward, the torque is transmitted to the left and right material distribution impellers 202 and 203 through the rotating shaft 201. Because the direction of the upper limit wheel 204 and the clamping tooth 302 of the right distribution impeller 203 is opposite to that of the left distribution impeller 202, the right distribution impeller 203 is restricted and will not rotate when the motor rotates forward. The blades of the left distribution impeller 202 push the limit wheel 204 to rotate synchronously. At this time, the limit tooth 206 of the limit wheel 204 rotates with the impeller, and its triangular three-dimensional structure's inclined surface will press against the clamping tooth 302 of the latch 3, causing the latch to temporarily move slightly outward, releasing the engagement state and allowing the impeller to rotate smoothly and push materials. After the motor stops working, the distribution impeller and the limit wheel 203... When the positioning wheel loses its driving force, the locking teeth 302 of the latch 3 spring back under the action of its own elastic reset structure and re-embed between the limiting teeth 206 of the limiting wheel. Since the limiting teeth and the locking teeth face opposite directions and the limiting groove 207 is rigidly matched with the impeller blades, the limiting wheel is completely locked at this time. The distributing impeller cannot rotate due to the weight of the material or vibration. The blades are fixed by the limiting groove and the limiting wheel is locked by the locking teeth, forming a double anti-rotation mechanism. When rotating in the opposite direction, the driving object is switched, so that the right distributing impeller 203 works and the left distributing impeller 202 is locked, which can adapt to different feeding needs, such as distinguishing two kinds of materials and controlling the amount of feed on one side.

[0028] In this embodiment of the utility model, a return spring 301 is fixedly connected to the outer end face of each buckle 3. The return spring 301 on the left buckle 3 is fixedly connected to the slot 109 on the base 1, and a fixing seat 303 is fixedly connected to the right side of the right buckle 3. The left end of the fixing seat 303 is fixedly connected to the return spring 301. The fixing seat 303 is fixedly installed on the right end of the outer shell 101 and is located on the right side of the slot 109. When the motor 2 drives the material dispensing impeller and the limiting wheel to rotate, the inclined surface of the limiting tooth 206 of the limiting wheel will squeeze the tooth 302 of the buckle 3, forcing the buckle 3 to move outward. At this time, the return spring 301 is compressed, and the material dispensing... The impellers rotate smoothly. According to the current driving direction of motor 2, only one material distribution impeller will rotate, while the other will not rotate due to the restriction of buckle 3. The material is then pushed out through the arc-shaped hole channel. After the motor stops working, the limit wheel stops rotating, and the limit tooth 206 no longer applies a pushing force to the buckle 302. The reset spring 301 releases the compression force, pushing the buckle 3 to spring back inward. The buckle 302 re-embeds between the limit teeth 206, forming a rigid clamp due to their opposite orientation. The buckles on the left and right sides are independently locked by the spring force of the base and the outer shell, respectively, ensuring that neither the left nor the right material distribution impeller can rotate when the machine stops.
