[0037] In the prior art, when the upper cover of a pet feeding device is opened, both hands are required to lift the upper cover forcefully to release the clamping connection between the upper cover and the body, and it is inconvenient to open the upper cover. Moreover, during the process of releasing the clamping connection between the upper cover and the body to open the upper cover, sometimes the upper cover will be clamped to the body again before the upper cover is flipped open, which brings trouble to the user.

[0038] The present utility model proposes an opening mechanism.

[0039] Please refer to Figures 1 to 5As shown in the figure, in an embodiment of the present utility model, the opening mechanism includes: a body 100, an upper cover 200, and a locking component. The upper cover 200 is rotatably connected to the body 100. The locking component includes: a locking frame 300, a movable seat 500, and a limiting seat 400. Among them, the limiting seat 400 is provided on the body 100, the movable seat 500 is movably connected to the body 100, the locking frame 300 includes a pressing portion 310, a rotating portion 330, and a clamping portion 320. The rotating portion 330 is rotatably connected to the upper cover 200. The locking frame 300 has a locking state in which it is clamped to the limiting seat 400 and an unlocking state in which it is disengaged from the limiting seat 400. When the upper cover 200 is buckled on the body 100, the clamping portion 320 is clamped to the limiting seat 400. When the pressing portion 310 is stressed, the locking frame 300 rotates, the clamping portion 320 disengages from the limiting seat 400, and the movable seat 500 abuts against the limiting seat 400.

[0040] In the specific implementation process, the body 100 is used to hold pet food. The upper cover 200 is located at the top of the body 100 and is used to cover the body 100. One side of the upper cover 200 is rotatably connected to the body 100, and the other side is clamped to the body 100 through a locking component. It can be understood that when placing a food container, such as a can, into the body, the upper cover 200 needs to be opened. In the normal state, the upper cover 200 and the body 100 are in a buckled state. At this time, the clamping portion 320 of the locking frame 300 is clamped to the limiting seat 400. When opening the upper cover 200, press the pressing portion 310 of the locking frame 300 to drive the locking frame 300 to rotate, so that the clamping portion 320 leaves the limiting seat 400 and the clamping connection between the clamping portion 320 and the limiting seat 400 is released. Then, flipping the upper cover 200 can open it. Of course, it can be understood that when the upper cover 200 is buckled towards the body 100 so that the clamping portion 320 of the locking frame 300 is clamped to the limiting seat 400, the buckling of the upper cover 200 can be achieved.

[0041] In this embodiment, the limiting seat 400 is provided on the top of the body 100. In order to improve the clamping strength, the limiting seat 400 and the body 100 are integrally formed. The movable seat 500 is movably located below the limiting seat 400. When the clamping portion 320 is clamped to the limiting seat 400, the movable seat 500 abuts against the clamping portion 320. When the clamping portion 320 leaves the limiting seat 400, the movable seat 500 abuts against the limiting seat 400. In this way, on the one hand, the contact between the movable seat 500 and the clamping portion 320 can improve the effectiveness of the clamping between the clamping portion 320 and the limiting seat 400. On the other hand, when the clamping portion 320 is being clamped to the limiting seat 400, the clamping portion 320 drives the movable seat 500 to leave the limiting seat 400, increasing the sense of resistance when the upper cover 200 is buckled.

[0042] The technical solution of the present utility model realizes the connection between the body 100 and the upper cover 200 through the latch assembly, and the connection between the upper cover 200 and the body 100 can be conveniently released through the latch assembly to open the upper cover 200. Specifically, the engaging portion 320 of the lock frame 300 is engaged with the limiting seat 400, so that the lock frame 300 is in a locked state. When the pressing portion 310 is stressed, the lock frame 300 rotates, and the engaging portion 320 disengages from the limiting seat 400, so that the lock frame 300 is in an unlocked state. In the unlocked state, the movable seat 500 also abuts against the limiting seat 400. In this way, only by applying a force to the pressing portion 310 to drive the lock frame 300 to rotate, the engaging portion 320 is disengaged from the limiting seat 400, and then the upper cover 200 is opened. Therefore, when the upper cover 200 is opened, there is no need to lift it forcefully, and the upper cover 200 is extremely convenient to open.

[0043] In one embodiment, referring to Figure 4 As shown, the lock frame 300 includes a driving arm 340 and a clamping arm 350, and the driving arm 340 and the clamping arm 350 are respectively connected to both ends of the rotating portion 330. The pressing portion 310 is provided at one end of the driving arm 340 away from the rotating portion 330, and the engaging portion 320 is provided at one end of the clamping arm 350 away from the rotating portion 330.

[0044] In this embodiment, one end of the driving arm 340 is connected to the pressing portion 310, and the other end is connected to the rotating portion 330. One end of the clamping arm 350 is connected to the engaging portion 320, and the other end is connected to the rotating portion 330. And, in the specific implementation process, a certain angle is formed between the driving arm 340 and the clamping arm 350, and the lock frame 300 is an L-shaped structure. The rotating portion 330 is connected with a rotating shaft 230 and is rotatably connected to the upper cover 200 through the rotating shaft 230. It can be understood that the pressing portion 310 is located on the side of the upper cover 200 facing away from the body 100, and the engaging portion 320 is located on the side of the upper cover 200 facing the body 100. By pressing the pressing portion 310, the lock frame 300 is rotated through the driving arm 340, and the clamping arm 350 rotates with the rotating portion 330 as the rotation center, thereby driving the engaging portion 320 to rotate in a direction away from the limiting seat 400. The engaging portion 320 is provided at one end of the clamping arm 350 and is bent toward one side of the clamping arm 350 for easy engagement with the limiting seat 400. It should be noted that in order to improve the strength of the lock frame 300, the driving arm 340, the clamping arm 350 and the rotating portion 330 are integrally formed structures. In addition, it can be understood that the pressing portion 310 and the driving arm 340 are integrally formed, and the clamping arm 350 and the engaging portion 320 are integrally formed.

[0045] Furthermore, referring to Figure 2 and Figure 3As shown, the lock assembly also includes a first reset member 600, one end of which is connected to the pressing portion 310, and the other end is connected to the upper cover 200. The first reset member 600 provides a driving force for the pressing portion 310 to reset. After the pressing portion 310 is pressed and displaced, the first reset member 600 can drive the pressing portion 310 to move in the opposite direction so that the reset member is reset to facilitate the next pressing action. In the specific implementation process, the pressing portion 310 and the upper cover 200 are both provided with guide columns 710, and there is a spacing space between the two guide columns 710 to ensure that the pressing portion 310 can be pressed smoothly. In addition, the first reset member 600 is sleeved on the outer periphery of the guide column 710, and the guide column 710 can also play the role of a guide support to prevent the first reset member 600 from bending and deviating and affecting the pressing and resetting of the pressing portion 310.

[0046] In one embodiment, the upper cover 200 includes a first shell 210 and a second shell 220, the first shell 210 and the second shell 220 surround and form a receiving space, the driving arm 340 and the first reset member 600 are both disposed in the receiving space, and one end of the first reset member 600 away from the pressing portion 310 is connected to the second shell 220.

[0047] Specifically, the first shell 210 and the second shell 220 are connected by snapping or screwing, and a storage space is formed between the two. The driving arm 340 and the rotating part 330 are located in the storage space, and the rotating part 330 is rotatably connected to the first shell 210 or the second shell 220. In this embodiment, the first shell 210 is located on the side away from the body 100, and the second shell 220 faces the body 100. In the specific implementation process, the first shell 210 is provided with a pressing port 211 connected to the storage space, and the pressing port 211 is used to accommodate the pressing part 310.

[0048] The pressing portion 310 extends out of the upper cover 200 through the pressing opening 211. Pressing the pressing portion 310 directly can drive the lock frame 300 to rotate, thereby moving the clamping portion 320 away from the limiting seat 400 to release the clamping. The driving arm 340 and the rotating portion 330 are both located in the accommodation space. In the specific implementation process, the second shell 220 is provided with a connecting seat 221, the rotating portion 330 is rotatably connected to the connecting seat 221, and the second shell 220 is provided with a movable opening, and the clamping arm 350 extends out of the accommodation space from the movable opening.

[0049] The clamping arm 350 extends out of the accommodation space through the movable opening. It can be understood that the clamping arm 350 rotates around the rotating part 330 so that the clamping part 320 clamps and moves away from the limit seat 400. There is a certain distance between the edge of the movable opening and the edge of the clamping arm 350 to avoid the clamping arm 350 and enable the clamping arm 350 to rotate smoothly. It should be noted that the first resetting member 600 is located in the accommodation space. One end of the first resetting member 600 is connected to the pressing part 310, and the other end is connected to the second housing 220. Press the pressing part 310 to compress the first resetting member 600. At the same time, the driving arm 340 and the clamping arm 350 rotate around the rotating part 330, so that the clamping part 320 leaves the limit seat 400, releasing the clamping, and flipping open the upper cover 200.

[0050] In one embodiment, referring to Figure 6 As shown, the upper cover 200 is connected with a rotating shaft 230. The upper cover 200 is rotatably connected to the body 100 through the rotating shaft 230. The opening mechanism further includes a torsion spring 240. The torsion spring 240 includes a body 241, a first torsion arm 242 and a second torsion arm 243. The body 241 is sleeved on the rotating shaft 230. The first torsion arm 242 abuts against the upper cover 200, and the second torsion arm 243 abuts against the body 100.

[0051] The upper cover 200 is rotatably connected to the body 100 through the rotating shaft 230. The torsion spring 240 is sleeved on the rotating shaft 230. The first torsion arm 242 and the second torsion arm 243 are respectively connected to the upper cover 200 and the body 100. When the upper cover 200 is buckled on the body 100, the torsion spring 240 is twisted and has a certain restoring elastic force. When the locking component releases the clamping, the restoring elastic force of the torsion spring 240 drives the first torsion arm 242 to rotate, and then drives the upper cover 200 to flip open. In this way, there is no need to lift the upper cover 200 with both hands forcefully. The upper cover 200 can be automatically flipped and opened under the action of the torsion spring 240. Moreover, during the opening process of the upper cover 200, under the action of the torsion spring 240, the upper cover 200 will not automatically flip and buckle towards the body 100, which is convenient to use and improves the user experience.

[0052] In one embodiment, the opening mechanism further includes an installation box 700. The installation box 700 is arranged in the body 100. The locking component further includes a second resetting member 510. The installation box 700 forms an installation cavity. The movable seat 500 is movably arranged in the installation cavity and is located on one side of the limit seat 400. The second resetting member 510 is arranged between the inner wall of the installation cavity and the movable seat 500 and is in abutting connection with the movable seat 500.

[0053] It should be noted that a receiving cavity 110 is formed inside the body 100. The receiving cavity 110 is used to accommodate a food bowl for holding food. Moreover, an opening 120 is provided at the top of the body 100, and the food container is placed in the receiving cavity 110 through the opening 120. In a specific implementation process, the mounting box 700 is located inside the receiving cavity 110 and is connected to the top wall of the receiving cavity 110 by screws, that is, the mounting box 700 is connected to the side of the top of the body 100 facing the receiving cavity 110. The movable seat 500 is movably arranged in the mounting box 700, and an installation cavity is formed by surrounding the top wall of the mounting box 700 and the frame. One end of the second reset member 510 is connected to the movable seat 500, and the other end is connected to the mounting box 700. The second reset member 510 makes the movable seat 500 contact the limiting seat 400. And further, one side edge of the movable seat 500 facing the clamping portion 320 extends out of the edge of the limiting seat 400. In this way, when the upper cover 200 is buckled on the body 100, the clamping portion 320 presses the movable seat 500 through the part of the movable seat 500 that extends out of the limiting seat 400, the second reset member 510 is compressed, so that the movable seat 500 leaves the limiting seat 400. Through the reset action of the first reset member 600, the locking frame 300 rotates, and further makes the clamping portion 320 rotate towards the limiting seat 400 to clamp the limiting seat 400. The clamping portion 320 is located between the movable seat 500 and the limiting seat 400. Under the elastic force of the second reset member 510, the top of the movable seat 500 abuts against the clamping portion 320, improving the stability of the clamping of the clamping portion 320. When the locking frame 300 rotates to make the clamping portion 320 leave the limiting seat 400, the movable seat 500 is lifted by the second reset member 510 to abut against the limiting seat 400.

[0054] Furthermore, a guide post 710 is provided in the mounting box 700, a guide hole is provided in the movable seat 500, and the movable seat 500 is slidably connected to the guide post 710 through the guide hole. The second reset member 510 drives the movable seat 500 to slide along the guide post 710 through the guide hole. The guide post 710 can play a role in guiding and limiting, avoiding bending and offset of the second reset member 510 during compression and elongation.

[0055] In an embodiment, the limiting seat 400 is provided with a guide inclined surface 410. One end face of the movable seat 500 facing the limiting seat 400 protrudes from the guide inclined surface 410 and forms a step for the clamping portion 320 to push the movable seat 500 away from the limiting seat 400 from the guide inclined surface 410.

[0056] It can be understood that during the process of closing the upper cover 200, under the action of the first reset member 600, the clamping portion 320 is offset toward the limiting seat 400 in the vertical direction to ensure smooth clamping on the limiting seat 400. In this way, during the process of the clamping portion 320 falling to the clamping portion 320, the guiding inclined surface 410 can play a guiding role, enabling the clamping portion 320 to move along the guiding inclined surface 410. A side wall connected to the guiding inclined surface 410 extends from the edge of the movable seat 500. When the clamping portion 320 moves along the guiding inclined surface 410 and leaves the guiding inclined surface 410, it can press on the movable seat 500, driving the movable seat 500 away from the limiting seat 400, and further enabling the clamping portion 320 to be smoothly clamped on the limiting seat 400.

[0057] The present utility model also proposes a feeder, which includes an open cover mechanism. The specific structure of the open cover mechanism refers to the above-mentioned embodiments. Since this feeder adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated one by one here.

[0058] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the inventive concept of the present utility model, or direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
