Example (b):
the embodiment discloses an intelligent door opening mechanism suitable for a garbage classification device with an upper door opening part, which comprises a lock cylinder and a lock tongue 9, wherein the lock tongue 9 is in a reverse L shape, the section of the short edge of the lock tongue 9 is in a circular arc shape, the lock cylinder is arranged on the side wall 2 of the garbage classification device, the lock cylinder 2 comprises a fixed plate 3 and a pressing plate 4 arranged on one side of the fixed plate 3, a pressure spring 5 is arranged between the fixed plate 3 and the pressing plate 4, a lock column 8 matched with the lock tongue 9 is arranged on the pressing plate 4, and the section of the top of the lock column 8 is in a circular arc shape; the pressing plate is characterized by further comprising a stepping motor 10, wherein the stepping motor 10 is connected with a first push rod 6, and one end of the first push rod 6 is tightly attached to the upper surface of the pressing plate 4 or arranged on the upper portion of the upper surface of the pressing plate 4.
Specifically, referring to fig. 1 to 3, the latch 9 is disposed on the box door 1 of the garbage classification device and perpendicular to the inner side surface of the box door 1, and the overall structure of the latch 9 is a reverse L-shaped: the long side of the lock is connected with the box door 1, the short side of the lock is used as a locking structure, and the section of the short side of the lock bolt 9 is arranged to be arc-shaped in order to facilitate the matching of the lock bolt 9 and the lock cylinder.
The lock cylinder is arranged in a side wall 2 corresponding to the box door 1 and comprises a fixed plate 3 and a pressing plate 4 arranged on the right side of the fixed plate 3, the fixed plate 3 is vertically fixed in the side wall 2, the upper part of the pressing plate 4 is hinged with the fixed plate 3, so that the pressing plate 4 can rotate, the lower part of the fixed plate 3 is also provided with a pressure spring 5, and two ends of the pressure spring 5 are respectively connected with the fixed plate 3 and the pressing plate 4; the pressing plate 4 is further provided with a lock column 8, the top section of the lock column 8 is arc-shaped, and when the lock tongue 9 presses the lock column, the friction force is relatively small because the short edge of the lock tongue 9 and the lock column 8 are both arc-shaped, so that the box door 1 is easier to open or close.
In order to realize automatic opening of the box door 1, the box door is further provided with a stepping motor 10, the stepping motor 10 is connected with a first push rod 6, the other end of the first push rod 6 is tightly attached to the upper surface of the pressing plate 4, when the stepping motor 10 rotates in the forward direction, the first push rod 6 pushes the pressing plate 4 leftwards to gradually compress the pressure spring 5, and the lock tongue 9 and the lock column 8 are separated, namely the box door 1 is opened; the backward stepping motor 10 rotates reversely, the pressure spring 5 expands, and the lock column 8 returns to the original position, so as to provide conditions for locking the box door 1 next time.
In some cases, the door 1 cannot be automatically opened due to a power failure or a malfunction of the stepping motor 10, and therefore, it is necessary to provide a manual opening mode of the door 1, and therefore, a second push rod 7 is provided, one end of the second push rod 7 clings to the pressing plate 4, and the other end is disposed outside the side wall 2 and connected to the door opening cap 11, and meanwhile, the second push rod 7 is horizontally disposed and parallel to the first push rod 6. When the door cannot be automatically opened, the door opening cap 11 is pressed down, the pressure spring 5 is compressed, the bolt 9 and the lock column 8 are separated, and the door 1 is opened immediately; then the door opening cap 11 is released, the pressure spring 5 is relaxed, and the lock column 8 returns to the original position, so as to provide conditions for locking the box door 1 next time.
In order to realize automatic door opening, another condition is that a garbage throwing person is detected, and the prior art generally adopts technologies such as code scanning, infrared portrait detection and the like for judgment, and the methods have respective advantages: the code scanning can more accurately judge whether the person is a garbage throwing person or not, is more accurate, but is slightly complicated and takes longer time; infrared portrait detection is faster, but relatively less accurate. The garbage classification device adopts a mode of adding the infrared detector on the outer side wall of the garbage classification device for identification, which mainly considers that the garbage classification device is faster and does not influence the mood of people throwing garbage.
In order to facilitate the opening of the box door 1, an elastic piece 13 is arranged between the box door 1 and the side wall 2, one end of the elastic piece 13 is fixed on the box door 1, the other end of the elastic piece is not fixed, and the box door 1 is automatically opened under the action of elasticity after the box door 1 is opened; the elastic member 13 may be a spring or a spring.
In order to realize automatic control, the controller 12 is further provided, the stepping motor 10 and the infrared detector are both electrically connected with the controller 12, forward rotation and reverse rotation of the stepping motor 10 can be controlled through the controller 12, detection results of the infrared detector can be processed at the same time, and the controller 12 can be a single chip microcomputer, and the structure of the controller is not described in detail because the controller is a conventional technology.
When in use, as shown in fig. 1, the whole structure is in a locking state; as shown in fig. 2, when the box cover needs to be opened, the stepping motor starts to rotate forward to push the first push rod to compress the pressure spring, the lock cylinder moves leftwards, when the lock cylinder moves to a certain position, the lock tongue can leave the lock cylinder, and the box cover is opened under the drive of the elastic piece; as shown in fig. 3, the entire structure is in an open state.
In the description of the present invention, it is to be noted that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and should not be construed as limiting the present invention.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the embodiments of the present invention are included in the scope of the present invention.
