[0079] The present invention provides a trash can which can be closed automatically. Figure 1 A schematic diagram of the trash can according to one embodiment of the present disclosure is shown.

[0080] like Figure 1 As shown, the automatically closing trash can 100 may include: a barrel body 110 , a cover body 120 and a support and reset device 130 .

[0081] The barrel body 110 may include a side portion 111 , a bottom portion 112 , and an opening portion 113 .

[0082] The side portion 111 and the bottom portion 112 form a space for accommodating garbage, and the formed space may be substantially in the shape of a square column, a cylinder, or any other suitable shape.

[0083] The opening 113 provides an opening for throwing in garbage. When a user uses the garbage can 100, the user opens the lid 120 and throws in garbage through the opening 113.

[0084] The barrel body 110 may be formed of plastic or metal such as stainless steel, and the capacity of the barrel body 110 may be set according to actual conditions.

[0085] In the use state, the cover 120 is located above the barrel 110, and one end of the cover 120 is rotatably connected to the barrel 110. The cover 120 may also include a handle 121, which is used to open the cover 120 when in use. Since one end of the cover 120 is rotatably connected to the barrel 110, the opposite end of the cover 120 can be opened, so that the user can put garbage through the opening 113.

[0086] When the cover 120 is closed, the cover 120 and the side portion 111 and the bottom 112 of the barrel 110 form a closed space for accommodating garbage.

[0087] In addition, rollers 140 may be further included at the lower side of the trash can 100 so as to drag the trash can 100 .

[0088] The trash can 100 may further include a rotation axis 150 , wherein the cover 120 may rotate around the rotation axis 150 , so as to open or close the cover 120 .

[0089] The connection between the cover body 120 , the barrel body 110 and the rotating shaft 150 will be described below by taking the cross-sectional shape of the cover body 120 and the barrel body 110 as an example of a square.

[0090] When the cover body 120 is in a square shape, its cross-sectional shape may include four sides, wherein at the first side (near the rotation position), the cover body 120 may include two or more cover body connectors 122 ( Figure 1 Two are shown in the figure), wherein two or more cover body connectors 122 are spaced apart from each other by a predetermined distance.

[0091] like Figure 1 As shown, the cover connector 122 is a connector extending from the side of the cover 120 by a predetermined distance. The connector 122 can be fixedly mounted on the cover 120 or integrally formed with the cover 120, and it can be a sheet-like structure.

[0092] One end of the cover connector 122 away from the cover 120 may include a mounting hole, through which the cover connector 122 can be sleeved at both ends of the rotating shaft 150 , so that the cover 120 can rotate relative to the rotating shaft 150 .

[0093] When the barrel body 110 is in a square shape, its cross-sectional shape may include four sides, wherein at the first side (near the rotation position), the barrel body 110 may include two or more barrel body connectors 114 ( Figure 1 Two are shown in the figure), wherein two or more barrel connectors 114 are spaced apart by a predetermined distance.

[0094] like Figure 1As shown, the barrel body connector 114 is a connector extending from the side of the barrel body 110 by a predetermined distance. The barrel body connector 114 can be fixedly mounted on the barrel body 110 or can be integrally formed with the barrel body 110, and it can be a sheet-like structure.

[0095] One end of the barrel body connector 114 away from the barrel body 110 may include a mounting hole, through which the barrel body connector 114 can be sleeved on both end positions of the rotating shaft 150, so that the barrel body 110 can rotate relative to the rotating shaft 150.

[0096] Although in Figure 1 The figure shows two cover body connectors 122 and two barrel body connectors 114, but those skilled in the art should understand that a suitable number of connectors can be selected.

[0097] According to the trash can 100 of the present invention, one end of the support and reset device 130 is fixedly connected to the side of the barrel body 110 so that the cover body 120 can close automatically, wherein when the opening angle of the cover body 120 is less than or equal to the first opening angle, the cover body 120 is automatically closed by the gravity of the cover body 120, and when the opening angle of the cover body 120 is greater than the first opening angle and less than or equal to the second opening angle, the cover body 120 is automatically closed by the support and reset device 130.

[0098] The first opening angle may be greater than 0 degrees and less than 90 degrees, for example, it may be 70 degrees, 75 degrees, 80 degrees, etc. The second opening angle may be greater than or equal to 90 degrees and less than 150 degrees, for example, it may be 100 degrees, 120 degrees, etc.

[0099] like Figure 1 As shown, the lower end of the support and reset device 130 can be fixedly connected to the barrel body 110, and the upper end of the support and reset device 130 is located near the rotating shaft 150.

[0100] For the sake of clarity, the following reference Figure 2 and Figure 3 The following is an enlarged view of the part shown for explanation.

[0101] Figure 2 An enlarged view of the support reset device 130 is shown, Figure 3 A cross-sectional view of the support and reset device 130 is shown.

[0102] like Figure 2 and 3 As shown, the support and reset device 130 may include an elastic member 131 , a cam eccentric member 132 and a cam shaft 133 .

[0103] One end of the elastic member 131 is fixedly connected to the side of the barrel 110, and the other end of the elastic member 131 is rotatably connected to the cam eccentric member 132. The cam eccentric member 132 includes an arc portion 1321 that is in sliding contact with the cam shaft 133. When the cover 120 is opened or closed, the arc portion 1321 is in sliding contact around the cam shaft 133. The cam shaft 133 can be the rotating shaft 150, or a shaft different from the rotating shaft 150, or can be sleeved on the rotating shaft 150.

[0104] The elastic member 131 includes a support rod 1311, an elastic member 1312 and an elastic member sleeve 1313. One end of the support rod 1311 is rotatably connected to the cam eccentric member, and the other end of the support rod 1311 is connected to the elastic member 1312, and the elastic member 1312 is accommodated in the elastic member sleeve 1313. When the cover body is opened, the cam eccentric member rotates and pushes the support rod 1311, and the support rod 1311 compresses the elastic member 1312. When the opening angle of the cover body 120 is greater than the first opening angle and less than or equal to the second opening angle, the cover body 120 is pushed back to the first opening angle by the restoring force of the elastic member 1312, so that the cover body 120 is automatically closed.

[0105] When the opening angle of the cover 120 is greater than the first opening angle, those skilled in the art should understand that the cover 120 cannot be automatically closed by the weight of the cover 120. However, due to the presence of the support reset device 130, the opening action of the cover 120 causes the elastic member 1312 in the elastic member 131 to be compressed. When the opening angle of the cover 120 is greater than the first opening angle and less than or equal to the second opening angle and the cover 120 needs to be closed, the compressed elastic member 1312 releases the elastic force, so that the cover 120 returns to the first opening angle through the action of the support rod 1311 and the cam eccentric member 132, and the cover 120 is closed from the first opening angle by its own weight.

[0106] In this way, under normal use, no operation is required when closing the cover, and the cover body 120 will close automatically.

[0107] The elastic member 1312 may be in the form of a spring or a hydraulic pressure, etc., which is not limited here.

[0108] Figure 4 a- Figure 4 c respectively show the situation that the cover 120 is closed, the opening angle is less than the first opening angle, and the cover 120 is fully opened. Figure 4 In state b, the cover 120 can be automatically closed according to its own gravity.

[0109] However, the opening angle may be greater than the first opening angle so that the opening angle of the cover 120 is larger, for example, fully opened.

[0110] The automatic closing trash can 100 according to the present disclosure may further include a limiting device 160 .

[0111] The limit device 160 allows the cover 120 to be opened to a second opening angle greater than the first opening angle, but when the cover 120 is opened to the second opening angle, the limit device 160 limits the opening angle of the cover 120 to be greater than the second opening angle. Figure 4 The first opening angle of b continues to open, so that the second opening angle can be reached.

[0112] The limiting device 160 includes a cover limiting member 161 , a barrel limiting member 162 , and a limiting locking member 163 .

[0113] The cover body stopper 161 is fixedly connected to the cover body 120 or formed integrally with the cover body 120 , and the barrel body stopper 162 is fixedly connected to the barrel body 110 or formed integrally with the barrel body 110 .

[0114] The cover body limit piece 161 and the barrel body limit piece 162 are arranged opposite to each other and form a limit space (a space partially surrounding the limit clamping piece 163). The limit clamping piece 163 is located in the limit space. When the cover body is opened to the second opening angle, the limit clamping piece 163 contacts both the cover body limit piece 161 and the barrel body limit piece 162 to limit the opening angle of the cover body 120 to be greater than the second opening angle.

[0115] The sides of the cover limiter 161 and the barrel limiter 162 facing the limiter 163 have an arc, which is configured to prevent the cover 120 from opening at an angle greater than the second opening angle and allow free rotation at an angle less than the second opening angle.

[0116] For example, when the opening angle is about to be greater than the second opening angle, since the limit stopper 163 is located between the cover limiter 161 and the barrel limiter 162 and has been in contact with the cover limiter 161 and the barrel limiter 162, the cover 120 will not be able to continue to rotate, thereby achieving the purpose of limiting.

[0117] There are two cover limiters 161 and two barrel limiters 162 , and the two cover limiters 161 are spaced apart and the two barrel limiters 162 are spaced apart. The support reset device 130 is at least partially located in the space between the two barrel limiters 162 .

[0118] like Figure 5 As shown, one end of the barrel limiting member 162 can be sleeved on the rotating shaft 150 to support the rotating shaft 150.

[0119] like Figure 5As shown, the limiting device 160 further includes a limiting control member 164, which controls the limiting stop member 163 to make the limiting stop member 163 leave the limiting space, thereby making the opening angle of the cover body 120 greater than the second opening angle.

[0120] The limit control member 164 includes a button 1641 and a spring 1642 (eg Figure 6 As shown, Figure 6 164 is a cross-sectional schematic diagram showing a limit control member 164 , wherein the control button 1641 causes the limit stop member 163 to leave the limit space, and the spring 1642 causes the limit stop member 163 to enter the limit space.

[0121] The limiting stopper 163 can leave the limiting space by shrinking or rotating to leave from the opening formed by the cover limiting member 161 and the barrel limiting member 162. When leaving, the limiting stopper 163 leaves by bending or twisting.

[0122] The limiting stopper 163 can be arranged only in the limiting space formed by the cover limiting member 161 and the barrel limiting member 162 on one side. The button 1641 and the limiting stopper 163 can be formed integrally, and a cavity is formed inside, and the spring 1642 is located in the cavity, and one end of the spring 1642 can be fixed to the cover limiting member 161 or the barrel limiting member 162 on the other side, so that the button 1641 can be turned to move out of the limiting space formed by the cover limiting member 161 and the barrel limiting member 162.

[0123] When the limiting stopper 163 leaves the limiting space, the cover 120 can continue to open to a larger angle than the second opening angle, so as to form a Figure 4 c shows the fully open state.

[0124] When the opening angle is greater than the second opening angle, the cover stopper 161 and the barrel stopper 162 are mismatched, so the stopper 163 will not return to the limit space. However, when the cover 120 is closed from an opening angle greater than the second opening angle, when the cover stopper 161 and the barrel stopper 162 form a certain space again, the stopper 163 returns to the limit space due to the action of the spring 1642. In this way, after the user controls the button 1641 to fully open, when closing the cover 120, there is no need to control the button 1641 again.

[0125] According to a further embodiment of the present disclosure, the automatic closing trash can 100 may further include an interconnection portion 170 (such as Figure 4 ), the interconnection portion 170 is used to connect the two automatic closing trash cans 100 to each other.

[0126] The interconnecting portion 170 includes a connecting pin 171 and a nesting opening 172, wherein the connecting pin 171 is located at one end of the cover body 120 and is rotatably mounted on the rotating shaft 150, and the nesting opening 172 is located at the other end opposite to the one end and is fixedly arranged on the barrel body 110 or is formed integrally with the barrel body 110, so that when the connecting pin 171 is inserted into the nesting opening 172, the two automatically closing trash cans are connected to each other.

[0127] Furthermore, two or more trash cans 100 may be connected in series so that a user can move two or more trash cans at a time.

[0128] The number of the connecting pins 171 and the nesting openings 172 is more than two. For example, in the case of two, the two connecting pins 171 are respectively located near the two outermost barrel body connecting pieces of the more than two barrel body connecting pieces.

[0129] According to a further embodiment of the present disclosure, Figure 7 As shown, the automatic closing trash can 100 may further include a capacity detection device 180 , which is used to detect the trash capacity in the automatic closing trash can 100 , and the capacity detection device 180 is installed on the inner side of the cover body 120 .

[0130] The capacity detection device 180 is located on the inner side of the cover body 120 near the connection between the cover body 120 and the barrel body 110 .

[0131] The detection plane of the capacity detection device 180 (represented by the straight line L1) is 90 degrees to the straight line L2, and the straight line L2 is a line connecting the capacity detection device 180 and the bottom edge of the barrel body 110 opposite to the connection between the cover body 120 and the barrel body 110.

[0132] When the cover body 120 has not undergone a predetermined action, the capacity detection device 180 is in a closed state, and when the cover body 120 has undergone a predetermined action, the capacity detection device 180 is activated.

[0133] The automatic closing trash can also includes a wake-up unit. When the wake-up unit detects that the cover has undergone a predetermined action, for example, the cover is closed again after the cover has been opened, the capacity detection device 180 is awakened so that the capacity detection device 180 is started.

[0134] When the capacity detection device 180 detects the garbage capacity in the automatically closed garbage bin, the detected garbage capacity is compared with the last detected garbage capacity to obtain a capacity change value. When the capacity change value reaches a predetermined threshold, the detected garbage capacity is transmitted to the server.

[0135] The circuit is normally in a closed state, and a level meter (or other sensors with vibration detection function such as a gyroscope) is used in the circuit to control the start of the circuit. Only when the cover is turned over, the circuit will wake up and start detection.

[0136] Each time the circuit detects, it will compare the currently detected capacity with the previous capacity. Only when the capacity change reaches the preset threshold will the communication function be started to report the change to the server. Otherwise, it will automatically shut down and wait for the next wake-up.

[0137] By setting the capacity detection device 180 near the rotating shaft 150, the resistance when the user opens the cover 120 can be reduced. In addition, the capacity detection device 180 can use the laser ranging principle to detect the distance of the highest point of the garbage in the barrel, and can calculate the vertical distance between the highest point of the garbage and the cover according to the trigonometric function method. If the cover 120 is forgotten to be closed, since the ranging distance is infinite, the server can be notified that the cover is not closed. In addition, through the above working method of the capacity detection device 180, the power consumption can be greatly reduced, thereby avoiding the need to replace the battery.

[0138] According to another embodiment of the present disclosure (this embodiment can refer to Figures 1 to 7 The invention relates to a trash can that can be understood and quoted from the relevant description.
