Each driving shaft 4 is provided with a driving portion 5. The two driving portions 5 drive the corresponding driving shaft 4 to rotate, so that the two opening and closing pieces 3 are assembled together with the driving shaft 4 to close the storage opening 1a or are separated from each other to open the storage opening 1a.

[0045] When the two opening and closing pieces 3 close the storage opening 1 a , the inner side wall of the storage opening 1 a cooperates with the opening and closing pieces 3 at the bottom to form a receiving area.

[0046] In actual use, there may be a time difference between the actions of the two motors. When closing the storage port 1a, one motor may rotate beyond the preset position while the other motor has not yet rotated to the right position, which may cause the storage port 1a to fail to be completely sealed. Preferably, the opening and closing piece 3 is provided with a limiting portion 32 for limiting its movement stroke, and the main body 1 is provided with a limiting member 6 that cooperates with the limiting portion 32 to flexibly abut. A protrusion 31 is provided on the first end of the opening and closing piece 3, and a connecting portion 311 is provided on the protrusion 31, and a limiting portion 32 is provided on the second end of the opening and closing piece 3. The two motors rotate at the same angle to ensure that the two opening and closing pieces 3 are completely sealed when they are assembled, and even if the ashtray falls, the ash can be prevented from leaking out of the storage port 1a.

[0047] In this embodiment, the connection portion 311 is a connection hole provided on the protrusion 31, and the drive shaft 4 is clamped on the connection hole of the opening and closing piece 3. The limiting portion 32 is a groove provided at the second end of the opening and closing piece 3, and the limiting member 6 is a convex column provided on the body 1, specifically convexly provided on the inner surface of the top cover 12, and the limiting member 6 is matched with the end point of the rotation path where the limiting portion 32 is located, that is, the position of the limiting portion 32 when the two opening and closing pieces 3 are spliced ​​together, so as to ensure that the two opening and closing pieces 3 are spliced ​​in place.

[0048] The opening and closing mechanism 2 also includes a positioning plate 7 provided on at least one of the upper and lower sides of the opening and closing piece 3. The positioning plate 7 is provided with a through hole 7a that matches the storage opening 1a. The positioning plate 7 is fixedly mounted on the body 1 and there is a gap between the positioning plate 7 and the opening and closing piece 3.

[0049] like Figure 4 , 8 As shown, in this embodiment, the positioning plate 7 is arranged on the upper and lower sides of the opening and closing piece 3, and the positioning plate 7 below the opening and closing piece 3 cooperates with the internal space of the cylinder body 11 to form a storage space for storing cigarette ash and cigarette butts, thereby reducing the harm caused by secondhand smoke. The circuit control board 10 is arranged between the top cover 12 and the positioning plate 7 located above the opening and closing piece 3, and the circuit control board 10 and the positioning plate 7 above the opening and closing piece 3 are sleeved on the convex ring 121. The drive shaft 4 passes through the positioning plate 7 located above the opening and closing piece 3, and the protruding column passes through the circuit control board 10. The middle part of the protruding column is provided with an annular groove, and the positioning plate 7 above the opening and closing piece 3 is sleeved on the annular groove. The positioning plate 7 below the opening and closing piece 3 abuts against the bottom of the protruding column, and is assembled with the protruding column by screws, so that the two positioning plates 7 are respectively arranged with a gap between the upper and lower surfaces of the opening and closing piece 3, and serve as a sealing plate to protect the rotation of the opening and closing piece 3, so as to prevent the cigarette butts, ashes, etc. in the cylinder body 11 from being too full and hitting the opening and closing piece 3, thereby affecting the normal use of the opening and closing piece 3.

[0050] like Figure 5-8As shown, the two opening and closing pieces 3 are centrally symmetrical. When the two opening and closing pieces 3 rotate, the two driving shafts 4 rotate in the same direction. The storage port 1a is a circular hole. The two opening and closing pieces 3 have the same shape and structure, which is convenient for batch processing. Taking one of the opening and closing pieces 3 as an example, its shape is specifically defined. The inner side wall of the opening and closing piece 3 includes a first arc segment 301 that is convexly arranged and a second arc segment 302 that is concavely arranged. The first arc segment 301 and the second arc segment 302 are connected to form an S shape. When the two opening and closing pieces 3 are assembled, the connecting portion 311 of one opening and closing piece 3 is arranged on the same side as the limiting portion 32 of the other opening and closing piece 3, and its corresponding limiting portion 32 is arranged on the same side as the connecting portion 311 of the other opening and closing piece 3.

[0051] Among the many optional opening and closing methods, the inner wall of the opening and closing piece 3 only adopts a design of concave and convex arc segments, which can make the opening and closing pieces 3 adapt to the shape of the inner wall of the storage opening 1a when they are away from each other, minimize the obstruction formed by the storage opening 1a, and maximize the opening area of ​​the storage opening 1a, making it convenient for cigarette ashes and cigarette butts to fall into the accommodating cavity.

[0052] The outer wall of the opening and closing piece 3 is a third arc segment 303 connected to the edge of one end of the protrusion 31. The third arc segment 303 is provided with a protrusion near its second end edge to cooperate with the second end edge of the opening and closing piece 3 to form a groove-shaped limiting portion 32. The outer surface where the protrusion is connected to the third arc segment 303 is a slope, and the second arc segment 302 is connected to the other end edge of the protrusion 31.

[0053] When the drive shaft 4 rotates clockwise, the two opening and closing pieces 3 move away from each other, and the third arc segment 303 touches the inner wall of the top cover 12; when the drive shaft 4 rotates counterclockwise, the two opening and closing pieces 3 are assembled with each other, and the grooves at their second ends cooperate with the protruding columns to limit the rotation angle of the drive shaft 4.

[0054] The ashtray provided by the utility model has a low structural complexity and is more convenient and quick to disassemble and assemble. It can realize automatic opening or sealing of the storage opening 1a. When the opening and closing piece 3 is in the open state, the storage opening 1a is less blocked, so that the actual opening area of ​​the storage opening 1a is larger, and ashes can be prevented from falling onto the opening and closing piece 3 as much as possible, thereby ensuring the cleanliness of the desktop and preventing ashes from being scattered. It is more environmentally friendly to use and has a beautiful appearance.
