In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0055] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] like Figures 1 to 9 As shown, this embodiment provides a pet food sealing mechanism, which can prevent pet food from spoiling, ensure the health of pet food, and improve the user experience of the pet feeder. The food storage container 100 of the pet feeder has a food outlet 1011, and the pet food sealing mechanism includes a fixing bracket 1, a sealing component 2 and a driving component 3.

[0057] Among them, see Figure 1 and Figure 2 The fixed bracket 1 is arranged on the main body shell 200 of the pet feeder, and the sealing assembly 2 includes a swing arm 21 and a sealing cover 22. One end of the swing arm 21 is rotatably connected to the fixed bracket 1, and the other end of the swing arm 21 is connected to the sealing cover 22. The sealing cover 22 has a first position (such as Figure 3 and Figure 4 As shown) and avoidance reveals the second position of the grain nozzle 1011 (as shown Figure 5 and Figure 6 The driving assembly 3 is disposed on the fixed bracket 1, and the driving assembly 3 is used to drive the swing arm 21 to drive the sealing cover 22 to switch between the first position and the second position.

[0058] The pet food sealing mechanism provided in this embodiment is such that when the food outlet 1011 does not discharge food, the sealing cover 22 is always in the first position, ensuring that the pet food in the food storage container 100 does not come into contact with the external air, and preventing the pet food from getting wet and spoiling. When it is necessary to feed the pet, the driving component 3 is controlled to make the swing arm 21 drive the sealing cover 22 to swing and switch to the second position, so that the food outlet 1011 is exposed, and to prevent the sealing cover 22 from obstructing the food outlet 1011 from discharging food. After the food outlet 1011 outputs a certain amount of pet food, the driving component 3 is controlled to drive the swing arm 21 to drive the sealing cover 22 to swing and switch from the second position to the first position, so that the sealing cover 22 re-seals the food outlet 1011. In other words, the pet food sealing mechanism can isolate the food outlet 1011 from the external environment, prevent the food outlet 1011 and the pet food in the food storage container 100 from being contaminated and spoiled, thereby improving the food safety of the pet and enhancing the user experience of the pet feeder.

[0059] Optionally, see 2 and Figure 3The driving assembly 3 includes a driving member 31 and a pushing block 32. The pushing block 32 is slidably connected to the fixed bracket 1. The output end of the driving member 31 is connected to the pushing block 32, which is used to drive the pushing block 32 to slide in the direction close to or away from the swing arm 21. After the pushing block 32 slides to contact the swing arm 21, it can push the swing arm 21 to drive the sealing cover 22 to swing from the second position to the first position. After the pushing block 32 slides to separate from the swing arm 21, the sealing cover 22 can swing from the first position to the second position with the swing arm 21 under the action of its own gravity. With such a configuration, the swing arm 21 can drive the sealing cover 22 to seal the grain outlet 1011 or avoid the grain outlet 1011 by controlling the moving direction and distance of the pushing block 32 through the driving member 31. The control is simple and easy to implement.

[0060] Specifically, Figure 3 As shown, the push block 32 and the swing arm 21 are spaced apart from each other (refer to Figure 3 The push block 32 supports the swing arm 21 so that the sealing cover 22 is in the first position. Figure 5 and Figure 6 As shown, when the driving member 31 drives the push block 32 away from and out of the swing arm 21, the force of the push block 32 on the swing arm 21 disappears, and the swing arm 21 drives the sealing cover 22 to swing away from the grain outlet nozzle 1011 to the second position under the action of gravity. Figure 6 After the push block 32 is driven to approach the swing arm 21 and contact the swing arm 21, when the push block 32 continues to slide in the current direction, the swing arm 21 swings toward the grain outlet nozzle 1011 under the thrust of the push block 32 until the sealing cover 22 seals the grain outlet nozzle 1011, thereby achieving sealing of the grain outlet nozzle 1011. Figure 4 shown.

[0061] Optionally, see Figure 7 and Fig. 9 The output end of the driving member 31 is connected to a screw rod 311, and a threaded hole 321 extending along the sliding direction is provided on the pushing block 32, and the screw rod 311 is threadedly matched with the threaded hole 321. Since the pushing block 32 is slidably connected to the fixed bracket 1, when the driving member 31 drives the screw rod 311 to rotate, the pushing block 32 can only move linearly relative to the screw rod 311, and the pushing block 32 can be moved closer to or away from the swing arm 21 by controlling the screw rod 311 to rotate forward or reverse. The threaded matching method of the screw rod 311 and the threaded hole 321 makes it easier to control the moving stroke of the pushing block 32, and the control accuracy is high.

[0062] Exemplarily, the driving member 31 is a motor, which can be communicatively connected to the control module of the pet feeder. The control module controls the opening and closing of the motor according to the pet feeding mode selected by the user to realize the electric control of the swing arm 21, which is more intelligent.

[0063] In other embodiments, the driving member 31 may also be a linear driving mechanism such as a cylinder, and the output rod of the cylinder is directly connected to the pushing block 32 to drive the pushing block 32 to move linearly.

[0064] In other embodiments, the driving component 3 may also be a rotary driving motor, and the output end of the rotary driving motor is directly connected to the rotating end of the swing arm 21 to drive the swing arm 21 to swing.

[0065] Optionally, see Figure 3 and Fig. 9 The fixed bracket 1 includes a support seat 11 and a support plate 12. The support seat 11 is provided with a first mounting groove 111 and a second mounting groove 112. The driving member 31 is fixed to the first mounting groove 111. The pushing block 32 is slidably provided in the second mounting groove 112. The swing arm 21 is rotatably connected to the support seat 11. The support plate 12 is provided at one end of the support seat 11 and is fixedly connected to the main housing 200. The support plate 12 is provided with an avoidance hole 121 opposite to the grain outlet nozzle 1011. The sealing cover 22 can pass through the avoidance hole 121 and seal the grain outlet nozzle 1011. The support seat 11 provides an installation foundation for the driving member 31 and the pushing block 32. The entire fixed bracket 1 can be fixed to the main housing 200 through the support plate 12, ensuring that the driving component 3 and the sealing component 2 are securely installed.

[0066] Specifically in this embodiment, see Figure 2 The main body shell 200 of the pet feeder is provided with a first connecting column 201, and the support plate 12 is fixed to the first connecting column 201 by a first fastener, so as to fix the support plate 12 to the main body shell 200. Exemplarily, the first fastener is a screw, and the main body shell 200 is provided with four first connecting columns 201, each of which is provided with a first screw hole, and the support plate 12 is provided with first connecting holes corresponding to the four first connecting columns 201. The support plate 12 can be fixed by passing the screw through the first connecting hole and tightening it in the corresponding first screw hole.

[0067] Further, see Figure 3 The driving member 31 is limited to the first installation groove 111 by the limiting plate 13, and the support seat 11 is provided with a second connecting column 113. The limiting plate 13 is fixed to the second connecting column 113 by a second fastener, so that the driving member 31 can be detachably installed. In this embodiment, the second fastener is a screw, and the second connecting column 113 is provided with a second screw hole. The limiting plate 13 is provided with a second connecting hole opposite to the second screw hole. After the driving member 31 is placed in the first installation groove 111, the limiting plate 13 is placed on the outside of the driving member 31, and the limiting plate 13 can be fixed by passing the screw through the second connecting hole and screwing it into the second screw hole, so as to ensure that the driving member 31 is securely installed.

[0068] See also Figure 7A plurality of material reduction grooves 123 are provided on the support plate 12. The plurality of material reduction grooves 123 can realize a lightweight design of the support plate 12 while ensuring the structural strength of the support plate 12, reducing material usage and lowering manufacturing costs.

[0069] Optionally, see Figure 7 and Fig. 9 , the opposite side walls of the second mounting groove 112 are provided with a slide groove 1121, and the opposite sides of the push block 32 are provided with a sliding portion 323, and the two sliding portions 323 are slidably matched with the two slide grooves 1121 in a one-to-one correspondence to achieve the sliding connection between the push block 32 and the support seat 11. Exemplarily, the sliding portion 323 is a convex strip convexly provided on the push block 32, and the cooperation between the convex strip and the slide groove 1121 can ensure the sliding stability of the push block 32 and provide guidance for the sliding direction of the push block 32.

[0070] In other embodiments, a sliding groove 1121 may be provided on the side wall of the second installation groove 112 , and a sliding portion 323 may be provided on the pushing block 32 .

[0071] Optionally, see Figure 7 and Fig. 9 One end of the swing arm 21 is rotatably connected to the support seat 11 through the rotating shaft 211, and the other end of the swing arm 21 is provided with a first clamping structure, and the sealing cover 22 is provided with a second clamping structure, and the first clamping structure is clamped with the second clamping structure. Fig. 9 As shown, the support base 11 is provided with rotation holes 114 on both opposite side walls of the second mounting groove 112, and the rotating shaft 211 is rotatably matched with the rotation hole 114 to realize the rotation connection between the swing arm 21 and the support base 11. The first clamping structure cooperates with the second clamping structure so that the sealing cover 22 can be disassembled, which is convenient for cleaning or replacing the sealing cover 22 later.

[0072] Optionally, see Figure 7 and Fig. 9 The first clamping structure includes a clamping plate 212 disposed on the swing arm 21, a clamping hole 2121 is provided on the clamping plate 212, and an elastic clamping hook 2122 is provided in the clamping hole 2121 of the clamping plate 212. Figure 8The second clamping structure includes a connected limiting portion 221 and a connecting portion 222. The end of the connecting portion 222 away from the limiting portion 221 is connected to the sealing cover 22. The connecting portion 222 is provided with a slot 2221. The clamping plate 212 can be inserted into the gap between the limiting portion 221 and the sealing cover 22, so that the bayonet 2121 is engaged with the connecting portion 222, and the elastic hook 2122 is engaged with the slot 2221. When the sealing cover 22 and the swing arm 21 are specifically assembled, it is only necessary to align the bayonet 2121 of the clamping plate 212 with the connecting portion 222 and clamp it in. During this process, the elastic hook 2122 can produce elastic deformation. When the bayonet 2121 and the connecting portion 222 are clamped in place, the elastic hook 2122 is clamped in the slot 2221 under the action of elastic force. At the same time, the clamping plate 212 is limited between the limiting portion 221 and the sealing cover 22, ensuring that the sealing cover 22 can be installed securely. When removing the sealing cover 22 , it is only necessary to apply force in the reverse direction to pull the sealing cover 22 to overcome the elastic force of the elastic hook 2122 so that the sealing cover 22 can be separated from the clamping plate 212 , and the disassembly and assembly operation is simple.

[0073] In this embodiment, the limiting portion 221 is a circular plate structure spaced apart from the sealing cover 22, an elastic hook 2122 is provided on each side of the bayonet 2121, and a slot 2221 is provided on each side of the connecting portion 222. The two elastic hooks 2122 are connected to the two slots 2221 in a one-to-one correspondence to ensure that the sealing cover 22 is securely installed.

[0074] In other embodiments, the first clamping structure may also be an inserting protrusion provided at the end of the swing arm 21, and the second clamping structure may be a slot provided at the sealing cover 22, and the inserting protrusion is inserted into the slot.

[0075] Further, in this embodiment, refer to Figure 7 and Figure 8 The opening side ring of the sealing cover 22 is provided with a flexible sealing edge 223, see Figure 1 and Figure 2 The grain discharging end of the grain storage container 100 is connected to a grain discharging barrel 101, and a grain discharging nozzle 1011 is arranged at the bottom of the grain discharging barrel 101. When the sealing cover 22 is switched to the first position, the flexible sealing edge 223 abuts against the bottom of the grain discharging barrel 101, thereby realizing that the sealing cover 22 is provided with a grain discharging nozzle 1011 (such as Figure 4 shown).

[0076] Optionally, see Figure 7 and Fig. 9A guide protrusion 322 is convexly provided on the push block 32, and a guide groove 213 is provided on the swing arm 21. The guide protrusion 322 can slide into or out of the guide groove 213. During the movement of the push block 32 toward the swing arm 21, the cooperation between the guide protrusion 322 and the guide groove 213 can limit the relative position of the swing arm 21 and the push block 32, so that the swing arm 21 can only swing along a preset trajectory, ensuring that the sealing cover 22 is provided with a grain outlet nozzle 1011. In addition, when the push block 32 is separated from the swing arm 21, during the swinging of the swing arm 21 toward the direction away from the grain outlet nozzle 1011, the guide groove 213 can avoid the screw rod 311 (such as Figure 6 As shown), the screw rod 311 is prevented from interfering with the swing of the swing arm 21.
