If the bin is full of garbage, a squeezing component is automatically controlled to squeeze the garbage inside the bin, thereby automatically determining whether the bin is full of garbage and automatically pushing down the squeezing component to squeeze the garbage.

Description

Technical Field

[0001] The invention relates to the field of garbage disposal, in particular to a garbage bin for automatically squeezing garbage. Background Art

[0002] The volume of the trash bin itself is limited, and the garbage is mostly piled up in the trash bin in a disorderly manner, taking up a lot of space, which makes the trash bin easy to be filled, and the user needs to clean the trash bin frequently. In response to this, some trash bins with a garbage squeezing function have appeared. The trash bins with a garbage squeezing function include a box body for accommodating garbage, an opening for the garbage to enter the box body at the top of the box body, and a squeezing component located above the box body, which can pass through the opening to enter the box body to squeeze the garbage inside the box body. However, the current trash bins with a garbage squeezing function are all judged by the user whether the trash bin is full of garbage, and after the trash bin is full, the user pushes down the squeezing component so that the squeezing component enters the box body to squeeze the garbage. It cannot automatically judge whether the trash bin is full of garbage, nor can it automatically push down the squeezing component to squeeze the garbage when the trash bin is full of garbage. Summary of the invention

[0003] The technical problem solved by the invention is to provide a garbage bin which can automatically squeeze garbage.

[0004] A garbage bin that automatically squeezes garbage includes a bin body for accommodating garbage, an opening is provided on the upper part of the bin body for garbage to enter the bin body, and also includes a squeezing component arranged above the bin body, the squeezing component moves down through the opening and squeezes the garbage inside the bin body, includes a controller and a photoelectric sensor, the photoelectric sensor is located at the upper edge of the bin body, the photoelectric sensor detects that there is garbage at the upper edge of the bin body and sends the detected information to the controller, and the controller controls the squeezing component to pass through the opening and enter the bin body to squeeze the garbage inside the bin body when it determines that the bin body is full of garbage.

[0005] A photoelectric sensor is used to detect whether there is garbage at the upper edge of the box to determine whether the box is full of garbage. If it is full of garbage, the squeezing component is automatically controlled to squeeze the garbage inside the box, thereby automatically determining whether the trash bin is full of garbage and automatically pushing down the squeezing component to squeeze the garbage.

[0006] Furthermore, the trash bin that automatically squeezes garbage includes a pressure sensor for detecting the reaction force exerted on the squeezing component when squeezing the garbage. The pressure sensor sends the detected reaction force exerted on the squeezing component to a controller. If the reaction force exerted on the squeezing component is large enough to reach a preset level, the controller controls the squeezing component to stop squeezing the garbage inside the bin.

[0007] Furthermore, the trash can that automatically squeezes garbage includes a position sensor for detecting the position of the squeezing component. The position sensor sends the detected position of the squeezing component to the controller. If the pressure sensor measures that the pressure on the squeezing component is greater than a threshold and the position sensor measures that the squeezing component is not lower than the upper edge of the box body, the controller sends a cleaning reminder signal to remind the user to clean up the garbage.

[0008] Furthermore, the squeezing component of the garbage bin that automatically squeezes garbage is a pressing plate, which includes an electric push rod that drives the pressing plate to move up and down and left and right balancing pieces located on both sides of the electric push rod. The left and right balancing pieces are fixedly installed on the pressing plate. The electric push rod drives the pressing plate and the left and right balancing pieces to move downward through the opening into the interior of the bin to squeeze the garbage inside the bin.

[0009] Furthermore, the trash bin that automatically squeezes garbage includes a pressure sensor located at the connection between the pressing plate and the electric push rod. The pressure sensor detects the reaction force exerted on the pressing plate and sends the detected information to the controller. If the pressure exerted on the pressing plate is greater than a threshold, the controller controls the pressing plate to stop squeezing the garbage inside the bin.

[0010] Furthermore, in the trash bin that automatically squeezes garbage, the left and right balance pieces are respectively installed above the pressure plate, including a photoelectric sensor. The photoelectric sensor detects one of the balance pieces and sends the detected information to the controller. The vertical distance H from the photoelectric sensor to the upper edge of the box body is equal to the vertical distance L from the upper end of one of the balance pieces to the pressure plate. When the pressure plate and the upper edge of the box body are at the same height, the upper end of the balance piece is at the same height as the photoelectric sensor. If the pressure on the pressure plate is greater than a threshold and the photoelectric sensor can detect the balance piece, the controller sends a cleaning reminder signal to remind the user to clean up the garbage.

[0011] Furthermore, in the automatic garbage squeezing trash bin, the pressure sensor first detects the reaction force exerted on the squeezing component when squeezing the garbage before the position sensor detects the position of the squeezing component. If the pressure sensor measures that the pressure exerted on the squeezing component is greater than a threshold value, the position sensor detects the position of the squeezing component.

[0012] Furthermore, the automatic garbage squeezing trash bin comprises an outer shell, a top of the outer shell is provided with an entrance for placing the trash in, the box body is arranged inside the outer shell, a ramp is provided to connect the entrance to the opening, a vibration driving component for driving the ramp to vibrate and a photoelectric sensor are provided, the photoelectric sensor detects whether there is trash in the ramp and sends the detected information to the controller, if there is trash in the lower part of the ramp and the residence time is long enough to reach a preset degree, the controller controls the driving component to drive the lower part of the ramp to vibrate so as to vibrate the trash into the box body.

[0013] Furthermore, in the trash bin that automatically squeezes trash, if trash is still present after the ramp continues to vibrate for a preset vibration time, the controller sends a reminder signal to remind the user to clean up the trash.

[0014] Furthermore, an outlet for pulling out the bin body is provided on the front side of the shell of the automatic rubbish squeezing bin, and the upper edge of the outlet is higher than the bin body.

[0015] Furthermore, the automatic garbage squeezing trash bin comprises a perspective plate arranged on the upper part of the outlet, and the perspective plate shields the part of the outlet that is higher than the bin body.

[0016] Furthermore, the upper end of the perspective plate of the automatic garbage squeezing garbage bin is hinged to the upper edge of the outlet, and the lower end of the perspective plate rotates forward to open the upper part of the outlet.

[0017] Furthermore, the perspective plate of the automatic garbage squeezing garbage bin is hinged on the upper edge of the outlet through a self-locking rotating shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1 As shown, the automatic garbage squeezing garbage bin comprises a housing 1, the top of the housing 1 is provided with an entrance 2 for the garbage to be put in, and the entrance 2 is provided with a ramp 3 for the garbage to slide down. Figure 2 As shown, a box 4 for accommodating garbage is provided below the ramp 3. Figure 3 As shown, the top of the box body 4 is provided with an opening 41 for the garbage to enter the box body 4. The garbage enters from the entrance 2, passes through the ramp 3, and falls into the box body 4 through the opening 41. Figure 2As shown, the bottom of the ramp 3 is mounted on the upper end of the box 4 through a tension spring 5, an eccentric motor 6 used as a vibration driving component is installed on the rear side of the lower part of the ramp 3, and a laser beam switch 7 is provided on the front side of the lower part of the ramp 3. The transmitting part and the receiving part of the laser beam switch 7 are respectively installed on the left and right sides of the housing 1 ( Figure 2 The transmitting part can be seen in the figure, and the receiving part is not shown because it is blocked by the transmitting part. The garbage bin includes a controller (not shown in the figure). The laser beam switch 7 detects whether there is garbage at the lower part of the ramp 3 and sends the detected information to the controller. If the laser beam switch 7 detects that there is garbage at the lower part of the ramp 3 and the residence time exceeds 30S, the controller determines that the garbage cannot automatically fall into the box body 4, and then controls the eccentric motor 6 to drive the lower part of the ramp 3 to vibrate so that the garbage falls into the box body 4. If the vibration time exceeds 30S but the garbage still stays at the lower part of the ramp 3, the controller determines that the garbage blocks the ramp 3, and the controller sends a blocking reminder signal to remind the user to clean up the garbage.

[0023] like Figure 2 As shown, a laser beam switch 8 is provided at the upper edge of the box 4, and the transmitting part and the receiving part of the laser beam switch 8 are respectively installed on the left and right sides of the housing 1 ( Figure 2 The transmitting part can be seen in the figure, and the receiving part is not shown because it is blocked by the transmitting part). It is used to detect whether there is garbage located at the upper edge of the box 4 and send the detected information to the controller. If there is garbage located at the upper edge of the box 4, the controller determines that the box 4 is full of garbage and needs to be squeezed.

[0024] like Figure 3 and Figure 4As shown, a pressing plate 91 is arranged above the box 4, and an electric push rod 92 and left and right balance rods 93, 94 are arranged above the pressing plate 91 to drive the pressing plate 91 to move up and down, and the left and right balance rods 93, 94 are located on both sides of the electric push rod 92. Left and right bearings 13, 14 are respectively fixedly mounted on the housing 1, and the left and right balance rods 93, 94 are respectively fixedly mounted on the pressing plate 91 after passing through the left and right bearings 13, 14. The controller controls the electric push rod 92 to drive the pressing plate 91 to move downward, and the left and right balance rods 93, 94 move downward in the left and right bearings 13, 14, respectively, so that the pressing plate 91 maintains stability during the movement. A pressure sensor is provided at the connection between the pressing plate 91 and the electric push rod 92 (not shown in the figure because it is blocked by the pressing plate 91 and the electric push rod 92). The pressure sensor detects the reaction force on the pressing plate 91 and sends the detected information to the controller. The controller determines whether the pressing plate 91 has squeezed the garbage in the box 4 to the limit and cannot further reduce the volume of the garbage in the box 4 by continuing to squeeze it according to the reaction force on the pressing plate 91 detected by the pressure sensor. If the pressure sensor detects that the reaction force on the pressing plate 91 is large enough to reach a preset level, the controller determines that the pressing plate 91 has squeezed the garbage to the limit, and the pressing plate 91 no longer continues to squeeze the garbage in the box 4. If the reaction force on the pressing plate 91 detected by the pressure sensor does not reach the preset level, the controller determines that the pressing plate 91 has not squeezed the garbage to the limit, and the pressing plate 91 continues to squeeze the garbage to further reduce the volume of the garbage in the box 4.

[0025] like Figure 3 and Figure 4 As shown, a photoelectric sensor 12 is fixedly mounted on the housing 1 and located beside the left balance bar 93. The photoelectric sensor 12 is connected to the controller. The vertical distance H from the photoelectric sensor 12 to the upper edge of the box 4 is equal to the vertical distance L from the upper end of the left balance bar 93 to the pressure plate 91. Therefore, when the upper end of the left balance bar 93 moves to the position shown in FIG. Figure 5 , Figure 6 When the photoelectric sensor 12 is in the state ( Figure 6The pressing plate 91 in the figure is not shown because it is blocked by the upper edge of the box body 4. The pressing plate 91 just moves to the upper edge of the box body 4. In a garbage squeezing process, when the pressing plate 91 has squeezed the garbage to the limit, the photoelectric sensor 12 detects the position of the pressing plate 91 and sends the detected information to the controller: if the photoelectric sensor 12 cannot detect the left balance bar 93, it means that the pressing plate 91 is lower than the upper edge of the box body 4, and the controller determines that the box body 4 can continue to load garbage, so the pressing plate 91 is controlled to return to the original position, and the garbage squeezing process is completed; if the photoelectric sensor 12 cannot detect the left balance bar 93, it means that the pressing plate 91 is not lower than the upper edge of the box body 4, and the controller determines that the box body 4 can no longer load garbage, so the pressing plate 91 is controlled to return to the original position, and a cleaning reminder signal is sent to remind the user to clean up the garbage, and the garbage squeezing process is completed.

[0026] like Figure 7 As shown, the front side of the housing 1 is provided with an outlet 10 for the box body 4 to be pulled out. The upper edge of the outlet 10 is higher than the box body 4 to ensure that the box body 4 can be pulled out from the outlet 10 when it is full of garbage, and the box body 4 will not be stuck at the outlet 10 and cannot be pulled out because of the garbage located at the upper edge of the box body 4. A perspective plate 11 is provided at the upper end of the outlet 10 to block the part of the outlet 10 that is higher than the box body 4. The upper end of the perspective plate 11 is hinged to the upper edge of the outlet 10 through a self-locking shaft 15. The user can observe whether the garbage in the box body 4 is full through the perspective plate 11. When it is necessary to pull out the box body 4, the user pulls the lower end of the perspective plate 11 forward, so that the lower end of the perspective plate 11 rotates forward and is fixed at this position under the action of the self-locking shaft 15, thereby opening the upper part of the outlet 10, and then pulls out the box body 4 to clean up the garbage. The lower part of the box body 4 is also provided with a groove 42 for finger insertion. When it is necessary to pull out the box body 4, the finger is inserted into the groove 42 to pull out the box body 4.
