[0040] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

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.

[0042] 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.

[0043] like Figures 1 to 6 As shown, this embodiment provides a pet wet food squeezing mechanism, the pet feeder includes a food storage container, the food outlet end of the food storage container is connected to a flexible food outlet cylinder 100, and the bottom of the flexible food outlet cylinder 100 is provided with a food outlet nozzle 101, which can realize the quantitative control of pet wet food. The pet wet food squeezing mechanism includes a squeezing plate 1 and a lifting drive assembly 2.

[0044] Among them, see Figure 1 , Figure 2 and Figure 3 The squeezing plate 1 is configured to squeeze the flexible grain discharging cylinder 100 in the axial direction of the flexible grain discharging cylinder 100. The squeezing plate 1 is provided with an avoidance channel 11, and the grain discharging nozzle 101 extends through the avoidance channel 11. The output end of the lifting drive assembly 2 is transmission-connected with the squeezing plate 1, and is used to drive the squeezing plate 1 to move up and down along the axial direction of the flexible grain discharging cylinder 100, so as to squeeze the flexible grain discharging cylinder 100 to make the grain discharging nozzle 101 discharge grain. The setting of the avoidance channel 11 can prevent the squeezing plate 1 from interfering with the grain discharging nozzle 101, and ensure that the pet wet food can be squeezed to the set position (such as the feeding trough of the pet feeder) for easy consumption by the pet.

[0045] For example, Figure 2 As shown, the avoidance channel 11 is a through hole opened in the middle of the extrusion plate 1. Figure 3 and Figure 4 As shown, the connection between the flexible grain discharging barrel 100 and the grain discharging nozzle 101 forms a step structure, which can just fit with the edge of the through hole, so that the squeezing plate 1 applies squeezing force to the flexible grain discharging barrel 100 during the lifting process. The flexible grain discharging barrel 100 is made of rubber material, for example.

[0046] In other embodiments, the avoidance channel 11 may also be designed as an open groove (such as a U-shaped groove or a V-shaped groove) opened in the extrusion plate 1, and the step structure of the flexible grain discharge barrel 100 is engaged with the edge of the open groove.

[0047] The pet wet food extrusion mechanism provided in this embodiment is such that when the lifting drive component 2 drives the extrusion plate 1 to rise, the extrusion plate 1 can axially compress the flexible grain outlet cylinder 100, and the pet wet food in the flexible grain outlet cylinder 100 is squeezed out through the grain outlet nozzle 101 under the action of pressure and falls into the feeding trough of the pet feeder. When the lifting drive component 2 drives the extrusion plate 1 to descend, the extrusion plate 1 moves away from the flexible grain outlet cylinder 100, and the flexible grain outlet cylinder 100 returns to its original position and the pet wet food in the grain storage container is refilled into the flexible grain outlet cylinder 100. The lifting drive component 2 repeats the above working process, so that the grain outlet nozzle 101 can repeatedly output the pet wet food, realizing automatic feeding of the pet wet food. The lifting drive method has a simpler structure and is easy to implement. By controlling the lifting and lowering times of the extrusion plate 1, the single feeding amount of the pet wet food can be controlled, so as to achieve the purpose of balanced feeding and improve the convenience of using the pet feeder.

[0048] Optionally, see Figure 1 and Figure 2 The lifting drive assembly 2 includes a rotary drive member 21 and an eccentric wheel 22. The output end of the rotary drive member 21 is fixedly connected to the eccentric wheel 22. The eccentric wheel 22 is rotatably connected to the extrusion plate 1, so that the eccentric movement of the eccentric wheel 22 drives the extrusion plate 1 to rise and fall. Figure 3 and Figure 4 As shown in the figure, in the initial position, the flexible grain discharging cylinder 100 is in a natural state, the axis of the eccentric wheel 22 is located below the rotation axis of the rotating drive member 21, and the extrusion plate 1 has no force on the flexible grain discharging cylinder 100. When grain needs to be discharged, the rotating drive member 21 drives the eccentric wheel 22 to rotate. During this process, the axis of the eccentric wheel 22 continuously moves upward, and at the same time drives the extrusion plate 1 to rise and squeeze the flexible grain discharging cylinder 100. When the eccentric wheel 22 rotates to the position shown in the figure, the extrusion plate 1 is pushed upward and squeezes the flexible grain discharging cylinder 100. Figure 5 and Figure 6 In the state shown, the extrusion plate 1 rises to the highest position, completing a grain discharge. Figure 5 When the state shown continues to rotate, the extrusion plate 1 drops to the initial position along with the eccentric wheel 22, and the flexible grain discharging cylinder 100 returns to its original state. Repeating the above working cycle can make the grain discharging nozzle 101 repeatedly discharge grain, and the amount of pet wet food discharged can be controlled by controlling the number of times the flexible grain discharging cylinder 100 discharges grain.

[0049] In this embodiment, refer to Figure 2 and Figure 4 The eccentric wheel 22 is eccentrically connected to a connecting shaft, and a socket 221 is provided on the connecting shaft. The rotary drive member 21 is a rotary motor, and an insertion rod 211 is connected to the output end thereof. The insertion rod 211 is inserted into the insertion hole 221 to achieve the connection between the eccentric wheel 22 and the rotary motor. Furthermore, the cross-sectional shapes of the insertion hole 221 and the insertion rod 211 are both non-circular to prevent the eccentric wheel 22 from rotating relative to the insertion rod 211.

[0050] In other embodiments, the lifting drive assembly 2 may also be a linear drive mechanism such as a screw-nut mechanism.

[0051] Optionally, see Figure 2 , Figure 4 and Figure 6 The extrusion plate 1 is provided with a connecting portion 12 protruding thereon, and a mounting groove 121 is provided thereon, and the eccentric wheel 22 extends into the mounting groove 121 and rotates with the mounting groove 121. In this way, the eccentric motion of the eccentric wheel 22 can be converted into the lifting motion of the extrusion plate 1, thereby squeezing or loosening the flexible grain outlet cylinder 100, and realizing the output of the pet wet food from the grain outlet 101. Exemplarily, the connecting portion 12 is a vertical plate vertically connected to the extrusion plate 1, and the vertical plate and the extrusion plate 1 are integrally formed.

[0052] Further, see Figure 2The installation groove 121 is a strip groove, and the extension direction of the strip groove is perpendicular to the lifting direction of the extrusion plate 1. When the rotary drive member 21 drives the eccentric wheel 22 to rotate, the eccentric wheel 22 can slide in the strip groove along the extension direction of the strip groove to adapt to the eccentric movement of the eccentric wheel 22, ensuring that the extrusion plate 1 can only move up and down to prevent damage to the flexible grain discharge barrel 100.

[0053] Optionally, see Figure 2 A bearing 23 is provided in the mounting groove 121, and the eccentric wheel 22 is rotatably connected to the mounting groove 121 through the bearing 23. The provision of the bearing 23 can reduce the friction resistance between the eccentric wheel 22 and the mounting groove 121, and improve the lifting stability of the extrusion plate 1. In this embodiment, the bearing 23 can slide in the mounting groove 121 along the extension direction of the mounting groove 121 to adapt to the eccentric movement of the eccentric wheel 22.

[0054] Optionally, see Figure 1 and Figure 2 The extrusion plate 1 is provided with a first material reduction groove 13 on the periphery of the avoidance channel 11; and a plurality of second material reduction grooves 14 are provided on the side of the extrusion plate 1 facing away from the flexible grain discharge barrel 100. By providing the first material reduction groove 13 and the second material reduction groove 14, the extrusion plate 1 can be designed to be lightweight and the energy consumption of the rotating drive member 21 can be reduced, while the structural strength of the extrusion plate 1 can be ensured, the material consumption can be reduced, and the manufacturing cost can be saved.

[0055] In other embodiments, only the first material reduction groove 13 or the second material reduction groove 14 may be provided on the extrusion plate 1, as long as the extrusion plate 1 can work normally.

[0056] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, two lifting drive assemblies 2 are provided, and the two lifting drive assemblies 2 are respectively connected to the two ends of the extrusion plate 1. That is, the two lifting drive assemblies 2 synchronously drive the extrusion plate 1 to lift or lower, which can improve the lifting stability of the extrusion plate 1, ensure that the flexible grain discharge barrel 100 is evenly stressed, and discharge grain more smoothly.

[0057] Exemplarily, the two lifting drive assemblies 2 each include a rotating drive member 21 and an eccentric wheel 22. Accordingly, a connecting portion 12 is provided at each end of the extrusion plate 1. The two eccentric wheels 22 are rotatably connected to the two connecting portions 12 one by one through a bearing 23.

The sealing plate 205 is provided with an opening opposite to the avoidance channel 11, and below the opening is the feeding trough on the base. The upper end of the flexible grain discharge barrel 100 is limited and fixed in the mounting hole 202, and the lower end of the flexible grain discharge barrel 100 is penetrated through the avoidance channel 11, and the grain discharge nozzle 101 is exposed through the opening. In the process of the lifting drive assembly 2 driving the extrusion plate 1 to lift and lower, the pet wet food squeezed out by the grain discharge nozzle 101 falls into the feeding trough. The setting of the sealing plate 205 can enclose the lifting drive assembly 2 in the space formed by the sealing plate 205 and the bottom wall of the accommodating chamber 201, ensuring the neat and beautiful appearance.

[0060] Furthermore, the pet feeder has a control module, which integrates one or more pet feeding modes. The lifting drive component 2 is communicatively connected to the control module. When the user selects a corresponding pet feeding mode, the control module controls the operation of the lifting drive component 2 according to the corresponding pet feeding mode, thereby realizing intelligent and automatic control of the pet feeder and further improving the user's experience.

[0061] Optionally, see Figure 1 and Figure 3 The bearing shell 200 is provided with a mounting seat 203 at the outer bottom of the accommodating chamber 201, and the lifting drive assembly 2 can be detachably mounted on the mounting seat 203.

Figure 1 As shown, the mounting seat 203 has a mounting cavity 2031, and the rotary drive member 21 of the lifting drive assembly 2 is placed in the mounting cavity 2031, and the rotary drive member 21 is fixed in the mounting cavity 2031 by a limiting plate 2032. Specifically, a connecting column 2033 is provided on the outer side of the mounting seat 203, and a threaded hole is provided on the connecting column 2033, and a through hole opposite to the threaded hole is provided on the limiting plate 2032. After the rotary drive member 21 is placed in the mounting cavity 2031, the limiting plate 2032 is placed on the outer side of the rotary drive member 21, and the limiting plate 2032 can be fixed to the mounting seat 203 by passing a screw through the through hole and screwing it into the threaded hole, so as to ensure that the rotary drive member 21 is securely installed.
