[0033] In one embodiment, the second drive unit is located at the top of the inner side of the main container 1, and the bottom of the second drive unit is connected to the top of the pressure plate 301. When the second drive unit is working, it can extend or shorten, thereby causing the pressure plate 301 to move up and down in the vertical direction inside the main container 1, thereby compressing the garbage put into the main container 1.

[0034] The bottom of the pressure plate 301 is provided with several barbs 302 that are long enough to penetrate the garbage inside the main container 1;

[0035] In one embodiment, a plurality of needles 302 are arranged in an array at the bottom of the pressure plate 301.

When the pressure plate 301 moves to its preset position, the needles 302 can completely penetrate the waste, and their length is greater than the thickness of the compressed waste.

[0036] The push plate 201 is connected to the first drive unit; the first drive unit drives the push plate 201 to reciprocate in the direction toward the outlet 103;

[0037] In one embodiment, the shape and size of the push plate 201 are the same as those of the outlet 103, and the push plate 201 can move to the outlet 103 under the drive of the first drive unit, so that the garbage can be completely pushed out; when the push plate 201 is reset under the drive of the first drive unit, the push plate 201 can be embedded in the opposite side wall of the outlet 103, so that one side surface of the push plate 201 is flush with the inner side wall of the main box 1, so that when the pressure plate 301 moves downward, it does not interfere with the push plate 201.

[0038] like Figure 3 and 4 As shown, the main housing 1 is equipped with a second drive unit, a pressure plate 301, and a filter plate 108. The filter plate 108 is located near the bottom of the inner side of the main housing 1 and is horizontally arranged. Its top surface is flush with the bottom side of the outlet 103, which facilitates smoother discharge of waste. The side wall of the main housing 1 below the filter plate 108 is provided with a drain hole 107 and connected to a pipe 106, which allows the liquid separated by the filter plate 108 to be discharged from the drain hole 107 into the pipe 106. The second drive unit is located at the top of the inner side of the main housing 1. The pressure plate 301 is horizontally arranged at the bottom of the second drive unit and can be driven by the second drive unit to move vertically inside the main housing 1. The bottom of the pressure plate 301 is vertically provided with several needles 302, which are used to puncture the waste packaging when the pressure plate 301 contacts the waste, breaking the sealed state of the container and causing the liquid inside to flow out.

[0039] The second drive unit includes a second drive mechanism, two sets of scissor arms, and a second guide mechanism. The second drive mechanism is located on the top inner side of the main housing 1 and includes two hydraulic push rods 307, two second guide rods 304, and two second movable seats 306. The two hydraulic push rods 307 are respectively located on two pairs of side walls of the main housing 1. The two second movable seats 306 are placed horizontally and are respectively connected to the movable ends of the two hydraulic push rods 307. The two ends of the two second guide rods 304 are respectively located on the inner side wall of the side housing 2 and are arranged parallel to the two sides of the hydraulic push rods 307. The two ends of the second movable seats 306 are also provided with horizontal guide holes, through which the second guide rods 304 pass to enhance the stability of the second movable seats 306 when moving.

[0040] The scissor arm is formed by several intersecting second links 308. The ends of the second links 308 on both sides of the upper end of the scissor arm are respectively hinged to one end of two second movable seats 306. When the hydraulic push rod 307 pushes the two second movable seats 306 on both sides closer or further away, the two sides of one end of the scissor arm will also move closer or further away, thereby causing the scissor arm to extend or retract.

[0041] The second guide mechanism is located on the top of the pressure plate 301 and includes two second guide rods 304 and two second sliding seats 305. Second side plates 303 are respectively provided on both sides of the top of the pressure plate 301. The two second guide rods 304 are respectively arranged parallel to the top of the pressure plate 301, with their ends connected to the second side plates 303 on both sides. The second sliding seats 305 have two sliding holes, allowing the two second guide rods 304 to pass through the two sliding holes, enabling the second sliding seats 305 to slide on the second guide rods 304. The second guide rods 304 guide the movement of the second sliding seats 305 and enhance the stability of the second sliding seats 305 during movement. The ends of the second connecting rods 308 on both sides of the lower end of the scissor arm are respectively hinged to one end of the two second sliding seats 305, allowing the second sliding seats 305 to move away from or towards each other as the scissor arm extends or retracts.

[0042] Specifically, there are two sets of scissor arms, which are respectively located at both ends of the second movable seat 306 to enhance the stability of the pressure plate 301 when it moves. When it is pressed down, there are four force points on the pressure plate 301 at the hinge, and the center of the scissor arms is located in the middle of the pressure plate 301. This ensures that the pressure plate 301 is in a horizontal state during compression, so that the garbage is subjected to uniform force.

[0043] More specifically, the second movable seat 306 is Ω-shaped, and the movable end of the hydraulic push rod 307 is connected to its concave part; the protruding part of the second movable seat 306 is located on one side of the middle section of the second movable seat 306, so that when the two second movable seats 306 are brought together, their protruding parts complement each other and fit together; this can provide the hydraulic push rod 307 with a longer space and working stroke, further ensuring its space utilization rate.

[0044] like Figure 3 and 5 As shown, the side box 2 is located on the outer side wall on the left side of the main box 1 and communicates with the interior of the main box 1. It is also located on the opposite side wall at the outlet 103. The side box 2 is equipped with a first drive unit and a push plate 201. The push plate 201 is vertically arranged and is driven by the second drive unit to move towards the outlet 103 inside the main box 1, so that the compressed waste is pushed out from the outlet 103 by the push plate 201.

[0045] The first drive unit includes a first drive mechanism, a scissor arm, and a first guide mechanism. The first drive mechanism is located inside the side housing 2 and includes a lead screw 206, two first guide rods 203, a motor, and two first movable seats 205. The motor is located inside the side housing 2. One end of the lead screw 206 is rotatably mounted on the inner wall of the side housing 2, and the other end is connected to the motor, which drives the lead screw 206 to rotate. The two ends of the two first guide rods 203 are respectively located on the inner wall of the side housing 2 and are parallel to each other on both sides of the lead screw 206. The thread directions at both ends of the lead screw 206 are opposite. The first movable seats 205 are provided with... It has a screw hole and two guide holes; the lead screw 206 passes through the screw hole, and the first guide rods 203 pass through the guide holes respectively. The two first movable seats 205 are respectively slidably disposed on the threads arranged in opposite directions at both ends of the lead screw 206. When the lead screw 206 rotates with the motor, the two first movable seats 205 move closer or further away. The two second guide rods 304 can enhance the stability of the first movable seats 205 during movement. The scissor arm has the same structure as the scissor arm in the second drive unit, which is composed of several intersecting first connecting rods 207. The ends of the first connecting rods 207 on both sides of one end are respectively hinged to one end of the two first movable seats 205.

[0046] The first guiding mechanism is located on one side of the push plate 201, including two first guide rods 203 and two first sliding seats 204. First side plates 202 are respectively provided at both ends of one side of the push plate 201. The two first guide rods 203 are respectively arranged parallel to one side of the push plate 201, with their ends respectively connected to the first side plates 202 on both sides. Two sliding holes are provided on the first sliding seats 204, allowing the two first guide rods 203 to pass through the two sliding holes, and allowing the first sliding seats 204 to slide on the first guide rods 203. The first guide rods 203 are used to guide the movement of the first sliding seats 204 and enhance the stability of the first sliding seats 204 during movement. The ends of the first connecting rods 207 on both sides of the other end of the scissor arm are respectively hinged to one end of the two first sliding seats 204, and can move away from or closer to the first sliding seats 204 as the scissor arm extends or retracts.

[0047] Specifically, there are two sets of scissor arms, which are respectively located at both ends of the first moving seat 205 to enhance the stability of the push plate 201 when it moves.

[0048] The working principle of this embodiment is as follows:

[0049] In this invention, a food waste compressor operates by activating a hydraulic push rod 307 during compression. This causes the second movable seats 306 on both sides to move closer together, and consequently, the two sides of one end of the scissor arm move closer together, extending the scissor arm and bringing the pressure plate 301 into contact with the waste. Subsequently, the spikes 302 below the pressure plate 301 puncture the waste packaging, allowing the liquid to flow out as much as possible during compression. The liquid then flows down through the filter plate 108 and is finally discharged into the pipe 106 through the drain hole 107. After compression, the sealing door 104 is lifted, exposing the outlet 103. The hanging ring 1043 on the door is then placed on the hook 1044 for fixation. Subsequently, the lead screw 206 inside the side housing 2 rotates under the drive of a motor, causing the first movable seats 205 at both ends to move closer together, extending the scissor arm and driving the push plate 201 to push the compressed waste out of the outlet 103 for collection.

[0050] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model.
