[0002] Ashtrays are used to hold cigarette ash. Common ashtrays are usually open and made of ceramic or porcelain, but they can also be made of glass, plastic, jade, or metal.
[0003] Most ashtrays commonly used in homes and hotels currently lack a sealing function. However, in some usage scenarios, such as semi-open balconies in hotel rooms, if the ashtray is not sealed, the ash inside can easily be blown around by the wind, making cleaning difficult and posing a risk of igniting flammable materials from unextinguished ash. Furthermore, without a seal, the smell of smoke can easily spread throughout the room. Patent CN218185179U discloses a mechanism for opening and closing an ashtray to prevent smoke from flying around, and an ashtray with an automatically opening and closing opening. This mechanism uses a closing plate in conjunction with a motor to open and close the ashtray opening. However, in order to accommodate the closing plate after opening and rotation, the opening of the ashtray in this solution is relatively small, making it more suitable for use as a temporary single-person ashtray in a car, and not suitable for use in living rooms or hotels.

[0035] like Figures 1-15As shown, this utility model provides a fan-shaped fully enclosed ashtray, comprising: a circular cylinder 1, with a central rotating cylinder 2 fixed in its middle, the central rotating cylinder 2 having a plurality of first circular grooves 21 vertically spaced along its body; a plurality of horizontally sized fan-shaped rotating blades 3, the top of each fan-shaped rotating blade 3 being a rotating blade collar 30, the rotating blade collar 30 being fitted one-to-one with the first circular grooves 21, each fan-shaped rotating blade 3 being able to rotate horizontally around the matched first circular groove 21, the arc edge of each fan-shaped rotating blade 3 being in contact with the inner wall of the circular cylinder 1, and the fan-shaped rotating blade 3... The sheet body is symmetrically provided with push blocks 31 of the same size near two straight edges. The push blocks 31 are vertical strips with their upper and lower parts extending vertically outward from the top and bottom surfaces of the fan-shaped rotating sheet 3, respectively. Among any two adjacent fan-shaped rotating sheets 3, the lower part of the push block 31 on one side of the upper fan-shaped rotating sheet 3 is located between the upper parts of the two push blocks 31 of the lower fan-shaped rotating sheet 3. When the upper fan-shaped rotating sheet 3 rotates about the central rotating cylinder 2, the side of the lower part of the push block 31 of the upper fan-shaped rotating sheet 3 pushes the side of the upper part of one or two push blocks 31 of the lower fan-shaped rotating sheet 3, causing the lower fan-shaped rotating sheet to rotate. 3. Coordinated rotation; Top rotating plate 4; It is rotatably connected to the top of the central rotating cylinder 2, and includes a top fan plate 43. The arc edge of the top fan plate 43 is connected to the inner side wall of the circular cylinder 1. The two straight edges of the top fan plate 43 extend downward and are respectively fixed with a high upright plate 42 and a low upright plate 41. The bottom edge of the low upright plate 41 is located between the two push blocks 31 of the highest fan-shaped rotating plate 3. The bottom edge of the high upright plate 42 is not higher than the lowest fan-shaped rotating plate 3. In the maximum open state, the plate body of the high upright plate 42 abuts against one straight edge of the highest fan-shaped rotating plate 3. Any two adjacent fan-shaped rotating plates... In the closed state, the upper fan-shaped rotating plate 3 has two push blocks 31 at the bottom with the two push blocks 31 at the top. In the closed state, the plate body of the high plate 42 is in contact with one straight edge of the lowest fan-shaped rotating plate 3, and the plate body of the low plate 41 is in contact with the inner side of the push block 31 at the top of the uppermost fan-shaped rotating plate 3 when it is closed. The inner side of the lower push block 31 at the bottom of any two adjacent fan-shaped rotating plates 3 is in contact with the inner side of the push block 31 at the top of the lower fan-shaped rotating plate 3 when it is closed.
[0036] In this technical solution, such as Figure 1As shown, during use, the user moves the top rotating plate 4 towards the low upright plate 41. At this time, the side wall of the high upright plate 42 touches the side of the uppermost fan-shaped rotating plate 3, causing them to rotate together. The push block 31 is a strip-shaped block fixed on the fan-shaped rotating plate 3, with its upper and lower parts extending vertically outward from the upper and lower surfaces of the fan-shaped rotating plate 3, respectively, and the outward extension length is greater than half the interval between the fan-shaped rotating plates 3. The bottom edge of the low upright plate 41 is lower than the top of the push block 31 in the uppermost fan-shaped rotating plate 3. After the top rotating plate 4 drives the uppermost fan-shaped rotating plate 3 to rotate at a certain angle, the lower part of the push block 31 of the uppermost fan-shaped rotating plate 3 abuts against the upper part of the push block 31 of the adjacent fan-shaped rotating plate 3 below, causing them to rotate together. The fan-shaped rotating plates 3 rotate according to... The ashtray rotates once, causing the adjacent fan-shaped rotating plates 3 below to rotate until they come together. At this point, the ashtray is fully open, making it convenient for the user to use. After use, the user moves the top rotating plate 4 towards the high upright plate 42. During this rotation, the low upright plate 41 presses against the push block 31 of the top fan-shaped rotating plate 3, causing the top fan-shaped rotating plate 3 to rotate together. Similarly, after the top fan-shaped rotating plate 3 rotates to a certain extent, it causes the next fan-shaped rotating plate 3 to rotate together. When the plate of the high upright plate 42 contacts the lowest fan-shaped rotating plate 3, the ashtray is fully closed. The user can easily open and close the ashtray by moving the top rotating plate 4. The structure is simple and not easily damaged.
[0037] In another technical solution, a brushless motor 5 is fixed to the top of the central rotating drum 2. The stator of the brushless motor 5 is fixed inside the central rotating drum 2, and the rotor of the brushless motor 5 is fixed to the top rotating plate 4. The brushless motor 5 is horizontally fixed to the top of the central rotating drum. A fixed support is provided inside the central rotating drum 2 to fix the stator of the brushless motor 5. The top of the top rotating plate 4 is a middle cover 40, which is installed on the rotor of the brushless motor 5. The top rotating plate 4 drives the fan-shaped rotating plate 3 under the drive of the brushless motor 5 to complete the opening and closing of the ashtray. The brushless motor 5 can be powered by a battery installed inside the central rotating drum 2, and the brushless motor 5 can communicate with an external controller.
[0038] In another technical solution, the inner sidewall of the circular cylinder 1 is provided with a cylinder circular groove 11 corresponding to the fan-shaped rotating plate 3. The arc edge of the fan-shaped rotating plate 3 is matched and slidably locked in the cylinder circular groove 11. Both ends of the fan-shaped rotating plate 3 are limited to avoid the downward deflection of the fan-shaped rotating plate 3 under long-term use, and also to better seal the inside of the circular cylinder 1.
[0039] In another technical solution, the lowest sector-shaped rotating plate 3 is not rotatable, thereby achieving a limiting effect on the other sector-shaped rotating plates 3 and the top rotating plate 4.
[0040] In another technical solution, a pre-drilled square hole 10 is provided on the side wall of the circular cylinder 1 on the side of the lowest fan-shaped rotating plate 3. A smoke extinguishing module 8 is fixed outside the pre-drilled square hole 10. The smoke extinguishing module 8 is a box-shell structure with one side open. The smoke extinguishing module 8 includes: a box-shell top plate 81, a box-shell back plate 83, a bottom slide plate 84, and a smoke extinguishing top block 7. The box-shell top plate 81 and the bottom slide plate 84 are respectively connected to the top and bottom edges of the pre-drilled square hole 10. The box-shell top plate 81 has several vertical cigarette insertion holes 80. The lit cigarette 9 is vertically inserted from the outside through the cigarette insertion holes 80, and the burning end abuts against the bottom slide plate 84. The opposite sides of the bottom slide plate each face... A guide plate 87 extends upwards, with a fixing block 82 extending upwards from the top surface of the guide plate 87, which is horizontal and close to one side of the circular cylinder 1. The top surface of the extinguishing top block 7 is attached to the bottom surface of the top plate 81 of the casing. A top block flange 72 extends horizontally outwards from each side of the extinguishing top block 7, and each top block flange 72 slides between the guide plate 87 and the top plate 81 of the casing. The end of the extinguishing top block 7 near the circular cylinder 1 is a pushing arc segment 71, which extends into the circular cylinder 1 from the reserved square hole 10. The distance that the pushing arc segment 71 extends into the circular cylinder 1 is equal to the distance between the extinguishing top block 7 and the back plate 83 of the casing. In this technical solution, to consider that a significant number of smokers often do not finish a cigarette in one sitting, a cigarette extinguishing module 8 is provided. When the cigarette 9 is only half-burned or just lit and the user needs to extinguish it before leaving the ashtray, the cigarette 9 is vertically inserted into the cigarette insertion hole 80, with the lit end of the cigarette 9 extending between the back plate 83 of the ashtray and the extinguishing top block 7. When the top rotating plate 4 rotates to the direction of the extinguishing module 8, since the pushing arc segment 71 is located inside the circular cylinder 1 and there is no misalignment between the pushing arc segment 71 and the inner wall of the circular cylinder 1, after the top rotating plate 4 rotates to the corresponding position, the upright plate 42 naturally pushes the extinguishing top block 7 towards the back plate of the ashtray during rotation. Pushing at direction 83 extinguishes the burning part of cigarette 9. The ash and tobacco residue produced during the burning of cigarette 9 slide down the bottom slide plate 84 into the round cylinder 1. When the user reuses the ashtray, the top rotating plate 4 rotates back, and the extinguishing block 7 is released, allowing the user to remove the unfinished cigarette 9. Optionally, the extinguishing block 7 near the back plate 83 of the casing can be set as a blade shape with a horizontal top and an inclined bottom. When cigarette 9 is vertically inserted into the extinguishing module 8, cigarette 9 is constrained by the insertion hole 80 and remains in a vertical state. The blade-shaped side wall of the extinguishing block 7 can easily cut off the burning part of cigarette 9 from above.
[0041] In another technical solution, a guide rod 85 is fixed between the fixed block 82 and the back plate 83 of the casing. The top block flange 72 has a through hole for the guide rod 85 to pass through. A return spring 86 is sleeved on each guide rod 85 and touches between the back plate 83 of the casing and the top block flange 72. In this technical solution, the top block flange 72 has a through hole 722 for the guide rod 85 to pass through. The extinguishing top block 7 can only move horizontally towards the back plate 83 of the casing. There is a flange block cavity 721 in the top block flange 72 around the guide rod 85 to accommodate the return spring 86. When the extinguishing top block 7 contacts the back plate 83 of the casing, the return spring 86 is fully compressed and is completely in the flange block cavity 721.
[0042] In another technical solution, the ashtray module 8 is enclosed by a control box 6, which contains a control circuit board 61 that is electrically connected to the brushless motor 5. In this technical solution, the control box 6 is equipped with a control button 62 that is electrically connected to the control circuit board 61. The control circuit board 61, the brushless motor 5, the control button 62, and the related power supply devices and electrical connection accessories are all readily available components on the market, and the connection methods involved are also existing conventional connection technologies. Users can open and close the ashtray by pressing the control button 62.
[0043] In another technical solution, the end of the high plate 42 is connected to an arc-shaped plate 44, which matches the shape of the side wall of the circular cylinder 1 and is flush with the height of the ashtray top block 7. When the ashtray is closed, the arc-shaped plate 44 in the top rotating plate 4 always abuts against the ashtray top block 7, resulting in a better ashtray extinguishing effect.
