Detailed implementation manner

[0067] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other.

[0068] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence.

[0069] In the present invention, unless otherwise stated, the orientation terms such as "upper", "lower", "top", "bottom" are usually in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction of the component itself; similarly, for the sake of understanding and description, "inner" and "outer" refer to the inner and outer of the contour of each component itself, but the above orientation terms do not limit the present invention.

[0070] As Figures 1 to 8 shown, the present invention provides a feeder, and the feeder can realize automatic feeding of pets. The feeder includes a main housing 100, an ordinary food bin 300, a first feeding structure 400, a food outlet channel 600, and a dinner plate 500. Among them, the main housing 100 is hollow inside and open at the top to form a receiving cavity 120 for accommodating the ordinary food bin 300 and the first feeding structure 400, and the ordinary food bin 300 and the first feeding structure 400 are arranged in the receiving cavity 120 in a vertically distributed manner.

[0071] The common food bin 300 is used to store the first food (not shown), which is the staple food for daily consumption by pets and is generally in the form of granules. The first feeding structure 400 is used to output the first food in the common food bin 300 according to a certain metering amount. The first feeding structure 400 has a discharge port 401. The first food outputted from the discharge port 401 of the first feeding structure 400 falls into the dinner plate 500 through the food discharge channel 600.

[0072] The dining tray 500 is located outside the main shell 100, and the feeding channel 600 is used to transport the first food output by the first feeding structure 400 to the dining tray 500. Part of the feeding channel 600 is located in the receiving cavity 120, and the other part extends to the outside of the main shell 100. The outer wall of the main shell 100 is provided with an escape opening (not shown) for the feeding channel 600 to pass through. Specifically, the upstream end of the feeding channel 600 is located at the feeding port 401, and the downstream end of the feeding channel 600 is opposite to the dining tray 500. In order to facilitate the feeding channel 600 to smoothly transport the first food at the feeding port 401 to the dining tray 500 without the action of external force, the feeding channel 600 is arranged at an acute angle with the vertical direction of the feeder, so that the first food can smoothly fall into the dining tray 500 under the action of its own gravity.

[0073] The first feeding structure 400 is connected to the bottom of the common food bin 300, and includes a feeding bin 410 detachably arranged at the bottom of the common food bin 300, an impeller assembly 420 arranged in the feeding bin 410, and a first driving assembly 430 arranged below the feeding bin 410. The bottom end surface of the feeding bin 410 is provided with the above-mentioned discharge port 401, and the output end of the first driving assembly 430 extends from the bottom of the feeding bin 410 into the feeding bin 410, and is transmission-connected with the impeller assembly 420 to drive the impeller assembly 420 to rotate.

[0074] A connecting port 310 is provided at the bottom of the common food bin 300, and the connecting port 310 is located above the impeller assembly 420. The top of the feed bin 410 is an open end, so that the common food bin 300 is connected with the feed bin 410. The first food in the common food bin 300 can fall into the feed bin 410 through the connecting port 310, and the impeller assembly 420 delivers the first food from the discharge port 401 during rotation.

[0075] In one embodiment, if Figure 5As shown, the impeller assembly 420 includes a shaft portion 421 and at least one impeller blade 422 provided on the circumferential side wall of the shaft portion. The impeller blades 422 can be one, two, three, etc. The impeller blades 422 are equally spaced in the circumferential direction. Among them, the impeller blade 422 is in a fan-shaped block shape, and a fan-shaped material storage area 423 is formed between adjacent impeller blades 422. When the fan-shaped material storage area 423 rotates to the discharge port 401, the first food in the fan-shaped material storage area 423 falls through the discharge port 401 into the food discharge channel 600. In order to enable the first food in the fan-shaped material storage area 423 to fall into the food discharge channel 600 better and faster, the discharge port 401 is not only formed on the bottom surface of the feeding bin 410, but also a part of the discharge port 401 is formed at the bottom of the circumferential side wall of the feeding bin 410. Thus, the discharge port 401 is relatively open, which is more conducive to the first food falling into the food discharge channel 600.

[0076] In order to facilitate adding the first food into the ordinary food bin 300, the top of the ordinary food bin 300 is open. Considering that the external environment will affect the first food. For example, the moisture in the external environment will affect the taste of the first food, and the humid environment will also cause bacteria to grow on the first food. In addition, the first food is prone to getting worms when exposed to the air or attracting flying insects in the external environment. Therefore, as Figure 2 and Figure 3 shown, the top of the main housing 100 is also provided with an upper cover assembly 200. The upper cover assembly 200 can seal the top opening of the main housing 100 while closing the top opening of the ordinary food bin 300, ensuring that the first food is in a relatively enclosed space, which is beneficial to moisture-proof, insect-proof and mildew-proof of the first food. Preferably, the upper cover assembly 200 is detachably connected to the main housing 100, and can adopt a snap connection method, or a magnetic attraction, threaded connection method, etc.

[0077] Considering that pets may have the problem of unbalanced nutrition intake, the feeder is also provided with a special food bin 201 for storing the second food and a second feeding structure 700. The volume of the special food bin 201 is smaller than the volume of the ordinary food bin 300, and is used to place health care products or other functional pills for pets. The dosage of such health care products and functional pills is different from that of the first food and cannot be supplied by the ordinary food bin 300.

[0078] The composition of the second food is at least partially different from that of the first food. The second food can be selected as a health product or a medicine. Commonly used pet health products are mainly classified into the following categories according to their functions: The first category is for digestive system health (for example, hairball remover tablets / granules, which can help pets expel hairballs; probiotic tablets, which can regulate the intestinal flora and relieve diarrhea or constipation); The second category is for bone and joint health care (for example, calcium and phosphorus supplements, which can prevent osteoporosis; vitamin D3 chewable tablets, which can assist in calcium absorption); The third category is for skin and hair care (for example, fish oil soft granules, which can improve dry hair; vitamin E tablets, which can maintain skin health); The fourth category is for immune and nutritional supplements (compound vitamin tablets, which cover basic nutrients such as vitamins A, B, and C; trace element tablets, which supplement zinc, iron, selenium, etc.); The fifth category is for special function health care (for example, urinary system health care tablets, heart health care chewable tablets). During the feeding process, users can supplement nutrition according to the actual growth situation of the pet, which is beneficial to the healthy growth or health care of the pet.

[0079] In some special scenarios, when the pet is sick, the special food bin 201 can also be used to place the prescription tablets and pills that need to be fed during the illness, so as to ensure that the pet can take the pills according to the doctor's advice, which is beneficial to the pet's faster recovery. Of course, the above-mentioned second food includes but is not limited to health products and medicines, and can also be functional snack granules, customized nutritional tablets, etc. It should be noted that the form of the second food covers various forms such as tablets, chewable tablets, freeze-dried granules, etc.

[0080] On the contrary, if the above-mentioned special food bin 201 is not provided, then the user needs to regularly place the second food into the food tray 500. As a working user, it is actually very difficult to feed regularly. In addition, there are the following defects in manual feeding by the user: it is extremely easy to forget or overfeed, which to a certain extent affects the health of the pet.

[0081] Regarding the installation positions of the special food bin 201 and the second feeding structure 700, there are the following several installation methods.

[0082] The first installation method of the special food bin 201 and the second feeding structure 700 is as Figure 3 、 Figure 7 and Figure 8 shown. The special food bin 201 and the second feeding structure 700 are arranged in the upper cover assembly 200. The special food bin 201 is independent of the ordinary food bin 300, and the projections of the special food bin 201 and the ordinary food bin 300 on the horizontal plane at least partially overlap, so as to minimize the size of the feeder in the horizontal direction and make the overall structure more compact. Among them, the size of the special food bin 201 in the horizontal direction is larger than its size in the vertical direction, so as to make full use of the flat shape of the upper cover assembly 200 and reasonably utilize the space inside the upper cover assembly 200.

[0083] The top of the special food bin 201 is detachably provided with a cover 202. When it is necessary to place the second food into the special food bin 201, the cover 202 can be opened. During normal use, the cover 202 is in a normally closed state. The cover 202 is arranged higher than the top end surface of the upper cover 220 to facilitate the operation of the user's hand.

[0084] The special food bin 201 has a blanking port 2011, and the blanking port 2011 is located at the bottom of the upper cover assembly 200. A blanking channel 110 communicating with the blanking port 2011 is provided on the main housing 100. The blanking channel 110 is used to convey the second food supplied by the blanking port 2011 to the food tray 500. Among them, the area of the horizontal cross-section of the blanking port 2011 is smaller than the area of the horizontal cross-section of the blanking channel 110 to ensure that the second food can smoothly enter the blanking channel 110.

[0085] Specifically, the blanking channel 110 is located inside the main housing 100 and extends in the vertical direction. The vertical extension method can effectively shorten the length of the blanking channel 110 inside the main housing 100, which is beneficial to simplifying the layout structure inside the main housing 100 and reasonably utilizing the space inside the main housing 100.

[0086] Furthermore, the blanking channel 110 and the ordinary food bin 300 are arranged side by side and are located on the side of the ordinary food bin 300 facing the food tray 500. Thus, the setting difficulty of the blanking channel 110 can be effectively simplified, the structural complexity of the blanking channel 110 can be reduced, and the extension length of the blanking channel 110 can be shortened, and the internal space of the main housing 100 can be reasonably utilized. Among them, the blanking channel 110 and the ordinary food bin 300 are integrally formed, and the installation and positioning of two components, namely the ordinary food bin 300 and the blanking channel 110, can be realized through one installation, which simplifies the installation steps and improves the installation accuracy.

[0087] Specifically, as Figure 6 shown, the outer circumferential wall of the ordinary food bin 300 is recessed radially inward to form the above-mentioned blanking channel 110. Among them, a partition 111 extending in the vertical direction is provided on the inner wall of the blanking channel 110 close to the main housing 100. The partition 111 makes the blanking channel 110 into a tubular structure with four side walls to prevent the external environment from affecting the falling process of the second food in the blanking channel 110.

[0088] It should be noted that the second food in the blanking channel 110 can directly fall into the food tray 500, or can fall into the food tray 500 after falling into the food outlet channel 600. When the second food in the blanking channel 110 directly falls into the food tray 500, the upstream end of the blanking channel 110 is communicated with the blanking port 2011, and the downstream end of the blanking channel 110 faces the food tray 500.

[0089] A flexible sheet (not shown in the figure) or a flipping baffle (not shown in the figure) can be arranged in the blanking channel 110. When the second food drops in the blanking channel 110, the flexible sheet deforms or the flipping baffle flips, enabling the second food to pass through and smoothly drop along the blanking channel 110. The flexible sheet or the flipping baffle is used to close the blanking channel 110 when there is no blanking, so as to prevent the second food in the special food bin 201 from getting damp or being invaded by insects.

[0090] When the second food drops into the food outlet channel 600 and then drops onto the dinner plate 500, the upstream end of the blanking channel 110 is communicated with the blanking port 2011, and the downstream end is communicated with the food outlet channel 600. Among them, the downstream end of the blanking channel 110 is located above the food outlet channel 600, and the projections of the downstream end of the blanking channel 110 and the upstream end of the food outlet channel 600 in the vertical direction at least partially overlap. Thus, the second food dropping in the blanking channel 110 can smoothly drop into the food outlet channel 600 without setting up an intermediate transfer structure.

[0091] The second feeding structure 700 is configured to drive the second food to move towards the blanking port 2011. As Figure 7 and Figure 8 shown, the second feeding structure 700 includes a second driving mechanism 710 and a feeding impeller 720. The feeding impeller 720 is received in the special food bin 201, and the second driving mechanism 710 is in transmission connection with the feeding impeller 720 to drive the second food to move towards the blanking port 2011.

[0092] The feeding impeller 720 includes a hub portion 721 connected to the second driving mechanism 710 and a plurality of blades 722 arranged on the circumferential side wall of the hub portion 721. There is an annular area between the circumferential side wall of the hub portion 721 and the circumferential side wall of the special food bin 201, and the second food is received in the annular area.

[0093] The plurality of blades 722 equally divide the annular area, and the blanking port 2011 is located in the annular area. Among them, a fan-shaped area is formed between adjacent blades 722, and the blanking port 2011 has the same shape and size as the above-mentioned fan-shaped area, which is conducive to the second food dropping into the blanking channel 110. The gaps between the bottom edge and the side edge of the blade 722 and the bin wall of the special food bin 201 are smaller than the size of the second food, so as to prevent some of the second food from not being pushed by the blade 722 to the blanking port 2011.

[0094] The second driving mechanism 710 extends and distributes in the horizontal direction to reduce the space occupied by the second driving mechanism 710 in the vertical direction and minimize the size of the upper cover assembly 200 in the vertical direction as much as possible. As Figure 8As shown, the second driving mechanism 710 includes a second motor 711, a driving gear 712 disposed on the output shaft of the second motor 711, and a driven gear 713 disposed below the special food bin 201. The axle 7131 of the driven gear 713 extends upward into the special food bin 201 to be connected to the feeding impeller 720. When the second motor 711 operates, the driving gear 712 drives the driven gear 713 to rotate, and the driven gear 713 drives the feeding impeller 720 to rotate.

[0095] It should be noted that different sector areas formed between the blades 722 can hold second foods with different functions. For example, vitamin A can be placed in one sector area, and vitamin E can be placed in another sector area symmetric to it. By the forward and reverse rotation of the second motor 711, the feeding of second foods with different functions can be achieved. Specifically, different types of second foods can be fed at different time periods. For example, vitamin A is automatically fed in the morning, and vitamin E is automatically fed in the afternoon, which is very flexible and convenient to use.

[0096] Furthermore, an intermediate gear 716 can be provided between the driving gear 712 and the driven gear 713. In this embodiment, the intermediate gear 716 may not have a speed reduction function, and through the intermediate gear 716, it is convenient to realize the horizontal extension distribution of the second driving mechanism 710.

[0097] In one embodiment, more than one special food bin 201 is provided in the upper cover assembly 200. Each special food bin 201 is provided with a feeding impeller 720, and a driven gear 713 is connected below each feeding impeller 720. The outer diameter of the intermediate gear 716 is larger than the outer diameters of the driving gear 712 and the driven gear 713. By using one intermediate gear 716 to drive multiple driven gears 713 to rotate, multiple feeding impellers 720 can be driven by one second motor 711.

[0098] Even further, as Figure 9 shown, a sensing disc 714 is further provided on the axle 7131. Counting pieces 7141 are provided at equal intervals in the circumferential direction of the sensing disc 714 and are equal in number to the blades 722. A photoelectric sensor 715 cooperating with the counting pieces 7141 is further provided in the upper cover assembly 200. Thus, through the cooperation between the photoelectric sensor 715 and the counting pieces 7141, the usage situation of the second food in the special food bin 201 can be clearly understood, and the user can be reminded to supplement the second food in a timely manner.

[0099] To facilitate the installation of the second driving mechanism 710 in the upper cover assembly 200, the upper cover assembly 200 is separately provided. The upper cover assembly 200 includes a bottom plate 210 and an upper cover 220 covering above the bottom plate 210.

[0100] A concave cavity 203 is formed by the downward depression of the top end face of the upper cover 220, and the special food bin 201 is located in the concave cavity 203. In one case, the concave cavity 203 is the special food bin 201, and the cover body 202 is detachably arranged on the top of the concave cavity 203; in another case, as Figure 8 shown, the special food bin 201 is a separate bin body, the special food bin 201 is arranged in the concave cavity 203, and the cover body 202 can be detachably arranged on the top of the special food bin 201 or on the top of the concave cavity 203.

[0101] In order to detect whether the cover body 202 is installed in place, the upper cover assembly 200 further includes a cover body detection unit 230. As Figure 10 shown, the cover body detection unit 230 includes a first detection member 231 installed on the cover body 202 and a second detection member 232 arranged on the upper cover assembly 200. Among them, the first detection member 231 and the second detection member 232 are adjacent to each other, and there is an electrical signal cooperation between the first detection member 231 and the second detection member 232.

[0102] The cover body 202 is provided with a sealing ring, which is used to form a seal with the upper part of the upper cover assembly 200 after the cover body 202 is closed, so as to prevent the second food in the special food bin 201 from getting damp.

[0103] In an embodiment, the second detection member 232 is a Hall sensor arranged on the upper cover 220, the first detection member 231 is a magnetic member cooperating with the Hall sensor, the second detection member 232 is located in the accommodation space surrounded by the upper cover 220 and the bottom plate 210, and the first detection member 231 is located on the circumferential inner side wall of the cover body 202. In another embodiment, the first detection member 231 is an induction sheet and the second detection member 232 is a photoelectric sensor. When the cover body 202 is covered on the top of the special food bin 201, the first detection member 231 is located in the sensing groove of the second detection member 232. Of course, the cover body detection unit 230 includes but is not limited to the above structures, and other sensors can also be used, which will not be elaborated one by one here.
