Pets refer to creatures that people raise for spiritual purposes. The pet industry is now an emerging and vibrant project, and the feeding of pets is of vital importance. To this end, designing a pet feeding device that can autonomously feed pets has considerable economic and practical value.

[0003] The pet feeder in the prior art generally limits the pet's eating time by extending the food tray at a fixed time.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0020] Reference Figures 1 to 6 A pet feeding device comprises: a shell 1, a hatch 2 arranged on the shell 1 and a food tray arranged in the shell 1, the shell 1 is provided with a driving mechanism 3 and a hatch linkage mechanism 4, the hatch linkage mechanism 4 is transmission-connected to the output end of the driving mechanism 3, and is connected to the hatch 2, the driving mechanism 3 is used to drive the hatch linkage mechanism 4 to drive the hatch 2 to open and close.

[0021] Among them, the food tray 11 is arranged in the shell 1, which can prevent the pet from spilling food out of the food tray when eating; through the cooperation of the driving mechanism 3 and the hatch linkage mechanism 4, the hatch 2 can be automatically controlled to open and close, so as to provide food for the pet, which can effectively prevent the pet from entering the food tray 11 at any time and causing food waste such as trampling and spilling; and the hatch 2 can close the food tray 11 when feeding is not needed to prevent food from being contaminated and ensure the health of the pet; therefore, this solution can control the pet's food intake and the pet's eating time, which helps the pet to develop a good biological clock and eating habits, and avoid obesity or gastrointestinal problems caused by irregular eating.

[0022] Specifically, the driving mechanism 3 in this embodiment is a servo motor.

[0023] Specifically, the door linkage mechanism 4 is any one of a chain transmission structure, a belt transmission structure, and a spiral transmission structure.

[0024] In one embodiment, the door linkage mechanism 4 includes a transmission gear set 41 and a transmission rack 42; The transmission rack 42 is slidably disposed in the housing 1 , the transmission gear set 41 is transmission-connected to the output end of the driving mechanism 3 , and the transmission rack 42 is transmission-connected, and one end of the transmission rack 42 is slidably connected to the cabin door 2 .

[0025] Taking the driving mechanism 3 as a servo motor as an example, when the output end of the driving mechanism 3 rotates, the transmission rack 42 is driven to slide through the transmission gear set 41, and the rotational motion of the driving mechanism 3 is converted into the linear motion of the transmission rack 42, so that the transmission rack 42 is driven to push open or close the cabin door 2.

[0026] When the output end of the driving mechanism 3 stops rotating, the transmission gear set 41 and the transmission rack 42 are meshed with teeth, so the transmission rack 42 can be locked through the transmission gear set 41 to prevent the transmission rack 42 from being displaced when the driving mechanism 3 is not working. This embodiment can accurately control the linear movement of the transmission rack 42 to avoid the hatch 2 being incompletely closed, thereby weakening the effect of the device on quantitatively controlling the pet's feeding. Compared with driving the hatch 2 to open and close by belt drive, the drive belt is prone to loosening and fatigue fracture after long-term use, and when the mass of the hatch 2 is large, the drive belt is more likely to slip than the rack; in terms of the stability of the opening and closing of the hatch 2, the rotation amount of the drive mechanism 3 can be controlled by cooperating with the transmission gear set 41 and the transmission rack 42, and the opening and closing amount of the hatch 2 can be controlled occasionally; in comparison, by adjusting the gear ratio of the transmission gear set 41 and the motor speed, the displacement of the transmission rack 42 can be accurately controlled, and the opening and closing degree of the hatch 2 can be accurately controlled. The use effect of the belt drive is not as good as that of the transmission gear set 41 and the transmission rack 42 in this embodiment.

[0027] Specifically, the transmission ratio of the transmission gear set 41 can be designed to be fixed, thereby ensuring that the opening and closing action of the cabin door is stable and accurate.

[0028] In terms of later maintenance, the structure of the transmission gear set 41 and the transmission rack 42 is relatively simple, and the functions and connection methods of each component are clear at a glance. This allows technicians or users to quickly understand the working principle of the device and accurately determine the fault point during maintenance and inspection. For example, when the hatch 2 opens and closes abnormally, it can quickly check whether the gear is worn or the rack is stuck, thereby improving maintenance efficiency.

[0029] Specifically, the number of the transmission racks 42 can be any value from 1 to ten.

[0030] When there are fewer connection points between the transmission rack 42 and the hatch 2, there may be a slight deviation when the hatch 2 is opened and closed, so that the hatch 2 is not completely closed; in order to solve this problem. In one embodiment, the transmission gear set 41 includes a first transmission gear set 411 and a second transmission gear set 412, both of which are transmission-connected to the drive mechanism 3, and the transmission rack 42 includes a first transmission rack 421 and a second transmission rack 422, and the first transmission rack 421 and the second transmission rack 422 are both slidably connected to the hatch 2.

[0031] In this embodiment, there are at least two indirect connection points between the hatch 2 and the driving mechanism 3, which can further improve the stability of the hatch 2 during movement, balance the force on the hatch 2, reduce the tilting or jamming of the hatch 2 during movement, resulting in incomplete closing, and avoid the existence of a gap between the hatch 2 and the shell 1 to prevent pets from taking food from the gap.

[0032] Specifically, the number of gears in the second transmission gear set 412 is at least one more than the number of gears in the first transmission gear set 411 , so as to ensure that the first transmission rack 421 and the second transmission rack 422 can move in one direction.

[0033] For example, the second transmission gear set 412 includes a first gear 412-1 and a second gear 412-2. The first gear 412-1 is in transmission connection with the output end of the drive mechanism 3, and the second gear 412-2 is in transmission connection with the first transmission rack 421. The first transmission gear set 411 includes a third gear 411-1, a fourth gear 411-2, and a fifth gear 411-3. The third gear 411-1 is in transmission connection with the output end of the drive mechanism 3. The fourth gear 411-2 is in transmission connection with the fifth gear 411-3, and the fifth gear 411-3 is in transmission connection with the second transmission rack 422. When the output end of the drive mechanism 3 rotates, it drives the first gear 412-1 and the third gear 411-1 to rotate synchronously, and then drives the second gear 412-2 and the fifth gear 411-3 to rotate, causing the first transmission rack 421 and the second transmission rack 422 to move in the same direction.

[0034] Referring to Figure 2 and Figure 3 , in one embodiment, the sliding connection points of the first transmission rack 421 and the second transmission rack 422 with the hatch 2 are located on the same horizontal plane.

[0035] Regarding the design cost of the transmission gear set 41, the first transmission gear set 411 and the second transmission gear set 412 can be designed into a coplanar structure, eliminating the need for additional transitional gears or complex transmission mechanisms to compensate for height differences. This can reduce the variety of parts and machining complexity, while improving the interchangeability between gears and racks.

[0036] In terms of appearance, designing the first transmission gear set 411 and the second transmission gear set 412 into a coplanar structure can reduce the volume of the pet feeding device and further decrease the floor space occupied by the pet feeding device.

[0037] Regarding the effect of driving the hatch 2 to open and close, the coplanar sliding connection points can further ensure the smooth movement of the hatch 2, avoiding poor opening and closing caused by the height difference between the first transmission rack 421 and the second transmission rack 422, and further optimizing the sealing effect when the hatch 2 moves horizontally.

[0038] Specifically, in this embodiment, the gears in the first transmission gear set 411 and the second transmission gear set 412 that are in direct contact with the drive mechanism 3 (such as the first gear 412-1 and the fourth gear 411-1), and the gears that are in direct contact with the first transmission rack 421 and the second transmission rack 422 (such as the third gear 412-3 and the seventh gear 411-4) have the same transmission ratio, thus ensuring that the first transmission rack 421 and the second transmission rack 422 move in the same direction at the same speed, further optimizing the sealing effect when the hatch 2 moves horizontally.

[0039] Referring to Figure 2And Figure 3 In one embodiment, a transmission sensor 5 is fixed to one side of the transmission rack 42, and the transmission sensor 5 is communicatively connected to the drive mechanism 3; The transmission rack 42 is provided with a first induction structure 441 and a second induction structure 442 for triggering the transmission sensor 5; when the first induction structure 441 or the second induction structure 442 triggers the transmission sensor 5, the drive mechanism 3 stops driving the hatch linkage mechanism 4 to rotate or drives the hatch linkage mechanism 4 to reverse.

[0040] For example, during the process of closing the hatch 2, when the transmission rack 42 moves, the first induction structure 441 and the second induction structure 442 move synchronously. When the transmission rack 42 drives the hatch 2 to slide to the closed state, at this time, the first induction structure 441 is just within the sensing range of the transmission sensor 5. At this time, the drive mechanism 3 stops driving the hatch linkage mechanism 4 to rotate, and the transmission rack 42 stops moving, thus achieving the effect of closing the hatch 2; when the hatch 2 needs to be opened, the drive mechanism 3 drives the hatch linkage mechanism 4 to reverse, the transmission rack 42 resets, the first induction structure 441 leaves the sensing range of the transmission sensor 5, the transmission rack 42 continues to move, and the transmission rack 42 drives the hatch 2 to slide to the open state. At this time, the second induction structure 442 is just within the sensing range of the transmission sensor 5. At this time, the drive mechanism 3 stops driving the hatch linkage mechanism 4 to rotate, the transmission rack 42 stops moving, and the hatch 2 opens, allowing the pet to enter and put its head into the food tray to eat.

[0041] Specifically, both the first induction structure 441 and the second induction structure 442 are protrusions provided on the transmission rack 42, and the transmission sensor 5 is a push-type sensor. When the first induction structure 441 and the second induction structure 442 move to a position where they can press the transmission sensor 5, the drive mechanism 3 stops driving the hatch linkage mechanism 4 to rotate or drives the hatch linkage mechanism 4 to reverse.

[0042] By ingeniously arranging the first induction structure 441 and the second induction structure 442 on the transmission rack 42 and closely cooperating with the transmission sensor 5, the automatic control of the opening and closing of the hatch 2 is achieved, significantly improving the automation level of the device and bringing an extremely excellent user experience.

[0043] When the driving mechanism 3 is started, the power generated by it is accurately transmitted to the transmission rack 42 via the transmission gear set 41, driving the transmission rack 42 to slide smoothly within the housing 1. During this process, the first sensing structure 441 and the second sensing structure 442 installed on one side of the transmission rack 42 will move synchronously with the transmission rack 42. When the hatch 2 runs to the preset opening position, the second sensing structure 442 just triggers the transmission sensor 5, and the transmission sensor 5 immediately sends a signal to the driving mechanism 3. After receiving the signal, the driving mechanism 3 accurately controls itself to stop operating, ensuring that the hatch 2 is stably maintained in the open state for the pet to eat conveniently. On the contrary, when it is necessary to close the hatch 2, the driving mechanism 3 reverses, driving the transmission rack 42 to move in the reverse direction. When the first sensing structure 441 triggers the transmission sensor 5, the driving mechanism 3 will stop in time, and the hatch 2 will be accurately closed.

[0044] Comparing with the solution of setting the first sensing structure 441 and the second sensing structure 442 in the chain drive or belt drive structure, the latter has obvious drawbacks in actual operation. The chain or belt of the chain drive and belt drive structure is usually made of flexible materials. When they come into contact with the pressure sensor, it is very easy to deform, resulting in the dispersion of the pressing force and a great reduction in the pressing effect, thus making the transmission sensor 5 unable to accurately identify whether the hatch 2 has been opened or closed in place. In this case, the driving mechanism 3 will continue to operate. Even if the hatch 2 has reached the preset opening or closing position, the hatch linkage mechanism 4 will still drive the hatch 2 to continue moving. This will not only cause collision interference between the hatch 2 and other components such as the housing 1, seriously damage the structure of the hatch 2, affect the sealing performance and stability of the device, but also may lead to increased wear of the transmission components, greatly shorten the service life of the device, and increase the maintenance cost.

[0045] In this embodiment, the first sensing structure 441 and the second sensing structure 442 are applied to the transmission rack 42. The transmission rack 42 is generally made of high-strength metal materials and has excellent rigidity. Compared with the chain and belt, it can always maintain a stable shape during the movement process and will not deform due to contact with the transmission sensor 5. This ensures that when the first sensing structure 441 and the second sensing structure 442 trigger the transmission sensor 5, clear and accurate signals can be generated, enabling the driving mechanism 3 to respond in a timely manner, ensuring that the hatch 2 can be accurately moved in place each time, avoiding damage to the device caused by excessive opening and closing, and further improving the practicability and reliability of the entire pet feeding device.

[0046] Among them, the transmission sensor 5 can accurately control the start, stop and steering of the driving mechanism 3, so that the hatch 2 avoids unnecessary collisions and impacts during the opening and closing process. Compared with the traditional manual control or automatic control method lacking precise sensing, it can reduce the wear between components such as the transmission rack 42, the transmission gear set 41 and the hatch 2, thereby extending the service life of the entire device.

[0047] When there is a problem with the abnormal opening and closing of the hatch of the feeding device, the fault point can be quickly located by checking the working status of the drive sensor 5 and the sensing structure. For example, if the first sensing structure 441 fails to trigger the drive sensor 5, it may be that the sensing structure is damaged or the drive sensor 5 fails. The maintenance personnel can carry out targeted repairs or replacements, improving the maintenance efficiency and reducing the equipment downtime.

[0048] In this device, the entire process of opening and closing the hatch 2 does not require manual intervention, effectively avoiding the situation where the hatch fails to open or close properly due to human operation negligence, and greatly improving the convenience and accuracy of pet feeding. For example, during the period when the pet owner travels, the feeding device can still automatically and accurately complete the opening and closing operations of the hatch according to the preset program, ensuring that the pet eats on time.

[0049] In one embodiment, the hatch 2 includes a first hatch 21 and a second hatch 22 hinged to the first hatch 21. The first hatch 21 is hinged to the housing 1, and the drive rack 42 is slidably connected to the second hatch 22.

[0050] The hatch 2 innovatively adopts a folding design and is formed by connecting the first hatch 1 and the second hatch 22 through a special hinge structure. This folding hatch design greatly optimizes the space utilization efficiency of the device and brings many practical values to users.

[0051] When the hatch 2 needs to be opened, the drive mechanism 3 is activated to drive the hatch linkage mechanism 4 to start operating. The hatch linkage mechanism 4 moves the second hatch 22 in the direction close to the drive mechanism 3 by traction. During this process, the first hatch 21 remains relatively fixed with its hinge point on the housing 1 as the axis, while the second hatch 22 rotates around the hinge point of the first hatch 21. As the second hatch 22 moves, a certain angle gradually forms between the first hatch 21 and the second hatch 22, making the whole hatch 2 present a folded and opened state. Compared with the traditional translational or double-opening hatch, the occupied space of the hatch in the housing 1 is greatly reduced.

[0052] For example, in some pet living areas with limited space, traditional hatches may cause inconvenience due to occupying too much space when opened, while the folding hatch can easily solve this problem, ensuring that the pet feeding device can flexibly adapt to various environments.

[0053] When the pet has finished eating and it is necessary to close the hatch 2, the drive mechanism 3 rotates in reverse, driving the hatch linkage mechanism 4 to move in the opposite direction. The hatch linkage mechanism 4 pushes the second hatch 22 to move away from the drive mechanism 3. The second hatch 22 rotates around the hinge point with the first hatch 21, increasing the angle between the first hatch 21 and the second hatch 22 until the first hatch 21 and the second hatch 22 are arranged side by side. At this time, the hatch 2 is completely closed, effectively preventing dust and impurities from entering and ensuring the hygienic safety of the food in the food tray.

[0054] Specifically, the hinge axis of the first hatch 21 and the housing 1 is parallel to the horizontal plane, and the hinge axis of the second hatch 22 is parallel to the horizontal plane.

[0055] The food tray 11 is arranged below the hatch 2. When the hatch 2 opens and closes, it sweeps over the food tray 11, that is, the second hatch 22 sweeps over the food tray 11 under the drive of the hatch linkage mechanism 4 to open and close the pet feeding device for the pet to eat the food in the food tray 11.

[0056] Specifically, the food tray 11 is made of metal hardware. Compared with a food tray made of plastic, the metal hardware is easier to clean.

[0057] Specifically, in order to prevent the pet from hitting its head while eating, an anti-collision rubber strip is provided on the side of the second hatch 22 close to the food tray 11.

[0058] In one embodiment, a sliding groove 221 is provided on the second hatch 22. The sliding groove 221 is used to limit the moving distance of the transmission rack 42. And if the transmission rack 42 moves too fast, the second hatch 22 may disengage from the transmission rack 42 under the action of inertia. Therefore, the sliding groove 221 is provided. On the one hand, it can limit the moving distance of the second hatch 22, and on the other hand, it can prevent the second hatch 22 from getting out of control of the transmission rack 42, further improving the stability of the hatch 2 during movement.

[0059] In one embodiment, a food delivery control mechanism 9 is further provided in the housing 1. The food delivery control device 9 is used to control the amount of food flowing into the food tray 11 to achieve timed and quantitative control of the feeding amount.

[0060] Research findings show that for multi-pet families, the feeding requirements of different pets may vary. Existing pet feeders can only perform quantitative feeding for a single pet when implementing quantitative feeding, which is not applicable to multi-pet families. If quantitative feeding is to be carried out for each pet, multiple pet feeders need to be purchased, which is costly. Therefore, to solve the above technical problems and improve the versatility of the device, this embodiment provides a pet feeding device identification system, including: an identification device 6 and the pet feeding device described in any of the above embodiments. A distance sensing module 7 is provided on the pet feeding device, and the distance sensing module 7 is communicatively connected to the drive mechanism 3. The identification device 6 is used to be worn on the pet. When the identification device 6 enters the identification range of the distance sensing module 7, the distance sensing module 7 sends a drive signal to the drive mechanism 3 to open or close the hatch 2.

[0061] Taking a family with two cats as an example, one cat is overweight and needs to lose weight, which is called cat A, and the other cat has a normal weight and can eat normally, which is called cat B. The identification device 6 is worn on cat B. When cat A wants to eat cat food, cat A enters the identification range of the distance sensing module 7, and the hatch 2 does not open at this time. Therefore, the food intake of cat A can be controlled to assist cat A in losing weight.

[0062] Or, one cat is sick and needs to eat prescription food for treatment, which is called cat C, and the other cat can eat normally, which is called cat D. The pet feeding device is filled with prescription food for cat C's treatment. The identification device 6 is worn on cat C. When cat C wants to eat cat food, it enters the identification range of the distance sensing module 7, and the hatch 2 opens. In this way, it can be avoided that cat D eats cat C's prescription food and affects the treatment effect.

[0063] Through the mutual cooperation of the identification device 6 and the distance sensing module 7 in this embodiment, a single pet feeding device can be used to feed multiple pets simultaneously, which is suitable for multi-pet families. It can not only reduce the purchase cost of pet feeding devices but also reduce the floor area occupied by pet feeding devices.

[0064] In one embodiment, the sensing range of the distance sensing module 7 is 0 - 1m. If the sensing range of the distance sensing module 7 is set within 0 - 0.8m, when cat B or cat C wearing the identification device 6 is 0 - 0.8m away from the pet feeding device, the hatch 2 opens for it to eat.

[0065] For multi-pet families, this system can cooperate with the pet feeding device to achieve timed and quantitative feeding of pets, with a high degree of intelligence, further improving the user experience.

[0066] The above is a specific description of the preferred embodiment of the present invention. However, the present invention is not limited to the described embodiment. Those skilled in the art can make various equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations or substitutions are all included within the scope defined by the claims of this application.
