[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A flue gas purification mechanism, characterized in that it includes a smoke transfer chamber, a smoke exhaust fan, a smoke treatment box, a smoke filter structure, and an atomizer;

[0010] The smoke transfer chamber and the smoke treatment box are connected. The smoke treatment box is provided with a smoke filtration area and an atomized gas fusion area. The smoke filtration area is connected to the smoke filtration structure, and the atomized gas fusion area is connected to the atomizer.

[0011] The flue gas is drawn into the smoke treatment box through the smoke transfer chamber by the exhaust fan. A portion of the flue gas is filtered by the smoke filtration structure and discharged from the smoke treatment box. The remaining flue gas is mixed with the atomized gas generated by the atomizer in the atomizing gas fusion zone and discharged from the smoke treatment box.

[0012] Furthermore, the smoke treatment box is provided with a diversion structure, which is used to divert the smoke drawn into the smoke treatment box so that a part of the smoke is filtered by the smoke filtration structure and discharged from the smoke treatment box, while the remaining smoke mixes with the atomized gas generated by the atomizer in the atomizing gas fusion zone and is discharged from the smoke treatment box.

[0013] Furthermore, the smoke treatment box is provided with a smoke filtration zone and an atomized gas fusion zone along its length, with the smoke filtration zone located near the exhaust fan.

[0014] The smoke treatment box is equipped with a smoke filtration structure on the outer wall of the smoke filtration zone;

[0015] The smoke treatment box is located in the atomized gas fusion zone and has sub-exhaust channels and mounting frames distributed from top to bottom. The sub-exhaust channels and mounting frames are positioned directly opposite the middle smoke inlet of the smoke treatment box.

[0016] The atomizer is mounted in the mounting frame;

[0017] The sub-exhaust duct is equipped with an intermediate atomized gas outlet connected to the atomizer and a terminal atomized gas outlet connected to the outside.

[0018] The mounting frame forms a diversion structure. A portion of the smoke entering the smoke filtration zone is filtered by the smoke filtration structure under the obstruction of the mounting frame and then discharged from the smoke treatment box. The remaining smoke enters the sub-exhaust channel and mixes with and carries the atomized gas generated by the atomizer before being discharged from the smoke treatment box.

[0019] Furthermore, the smoke treatment box has horizontal and vertical ribs in the atomized gas fusion zone. The horizontal and vertical ribs extend from the outer side wall of the smoke treatment box to its inner side wall.

The inner opening of the mounting frame is sealed by the inner side wall of the smoke treatment box, and its outer opening is connected to the mounting port on the outer side wall of the smoke treatment box. The atomizer is inserted into the mounting port and installed in the mounting frame.

[0020] Furthermore, the atomizer includes a housing, a fixing plate disposed within the housing, a cotton wick held and fixed by the fixing plate, an end cap covering the opening at the upper end of the housing, and an atomizing plate fixed on the end cap, wherein the upper end of the cotton wick abuts against the atomizing plate.

[0021] Furthermore, the end cap includes an inner end cap and an outer end cap. The inner end cap covers the upper opening of the housing, and the inner end cap and the outer end cap cooperate to clamp and fix the atomizing sheet.

[0022] Preferably, the inner end cap and the housing are fixed together by a snap-fit ​​structure, as are the outer end cap and the inner end cap.

[0023] Preferably, two or more fixing plates are arranged in a ring shape, and a gap is formed between adjacent fixing plates that communicates with the inner cavity of the shell.

[0024] Furthermore, the smoke filtration structure includes filter cotton and a smoke exhaust window. The smoke treatment box is located in the smoke filtration area and has a filtered smoke outlet.

[0025] Furthermore, the smoke transfer chamber includes a horizontal smoke transfer chamber and a vertical smoke transfer chamber that are interconnected. The horizontal smoke transfer chamber has a smoke inlet extending along the width direction of the cigarette butt disposal chamber of the ashtray, and the vertical smoke transfer chamber has a smoke outlet connected to the exhaust fan.

[0026] Furthermore, the device includes a negative ion generator.

[0027] Furthermore, the negative ion generator's negative ion emitter is installed on the smoke transfer chamber or smoke treatment box (preferably, the negative ion emitter is installed on the vertical smoke transfer chamber; specifically, two pairs of negative ion emitters are symmetrically installed on the two side walls of the vertical smoke transfer chamber).

[0028] An ashtray, characterized in that it includes the aforementioned flue gas purification mechanism.

[0029] (III) Beneficial Effects

[0030] This utility model provides a flue gas purification mechanism and its ashtray, which has the following beneficial effects:

[0031] 1. The smoke in the ashtray is collected in the smoke transfer chamber by the exhaust fan and then enters the smoke treatment box. Some of the smoke is blocked by the mounting frame and discharged from the smoke filter structure on the outer wall of the smoke filter area. The remaining smoke that is not blocked by the mounting frame will enter the sub-exhaust channel at a high flow rate (under the action of the exhaust fan), increasing the fluidity of the (aromatherapy) atomized gas produced by the atomizer. On the one hand, the atomized gas can be quickly discharged into the surrounding environment by the remaining smoke, and at the same time, the radiation range is large, which can quickly achieve the air freshness of the surrounding environment. On the other hand, the discharge of atomized gas does not require the installation of an additional power source, which can effectively control the volume of the mechanism and even the entire ashtray.

[0032] 2. The remaining flue gas discharged through the terminal atomizing gas outlet can react with the atomizing gas in the sub-exhaust channel, specifically with the flue gas decomposition agent in the atomizing gas, to achieve flue gas purification;

[0033] 3. The facility is equipped with a negative ion generator, which can further purify the flue gas. Attached Figure Description

[0071] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0072] See attached document Figure 1-4 A flue gas purification mechanism includes a smoke transfer chamber 2, a negative ion generator, a smoke exhaust fan 5, a smoke treatment box 4, a smoke filter structure, and an atomizer 8.

[0073] The smoke transfer chamber 2 and the smoke treatment box 4 can be directly connected or indirectly connected through the exhaust fan 5 (the exhaust fan 5 is existing technology, and only the shell is shown in the attached drawings, without showing the internal fan, motor and other specific structures); the smoke treatment box 4 is provided with a smoke filtration area and an atomized gas fusion area, the smoke filtration area is connected to the smoke filtration structure, and the atomized gas fusion area is connected to the atomizer 8.

[0074] Under the action of the exhaust fan, the smoke is drawn into the smoke treatment box through the smoke transfer chamber. A portion of the smoke enters the smoke filtration zone and is filtered by the smoke filtration structure before being discharged from the smoke treatment box. The remaining smoke enters the atomizing gas fusion zone and mixes with and carries the atomized gas generated by the atomizer before being discharged from the smoke treatment box.

[0075] The smoke transfer chamber 2 includes a horizontal smoke transfer chamber 2.1 and a vertical smoke transfer chamber 2.2 that are interconnected. The horizontal smoke transfer chamber 2.1 is connected to the cigarette butt disposal chamber 1.1 of the ashtray, and the vertical smoke transfer chamber 2.2 is connected to the exhaust fan 5.

[0076] The negative ion generator's negative ion emitter 3 is installed in the vertical smoke transfer chamber 2.2. Specifically, two pairs of negative ion emitters 3 are symmetrically installed on both sides of the vertical smoke transfer chamber 2.2.

[0077] The smoke treatment box 4 is provided with a smoke filtration zone and an atomized gas fusion zone along its length, with the smoke filtration zone located near the exhaust fan 5.

[0078] The smoke treatment box 4 is provided with a smoke filtration structure on the outer wall 4.3 of the smoke filtration zone;

[0079] The smoke treatment box 4 is located in the atomized gas fusion zone and has sub-exhaust channels 4.9 and mounting frames distributed from top to bottom. The sub-exhaust channels 4.9 and mounting frames are positioned directly opposite the middle smoke inlet 4.2 of the smoke treatment box 4.

[0080] The atomizer 8 is installed in the mounting frame;

[0081] The sub-exhaust channel 4.9 is provided with an intermediate atomized gas outlet connected to the atomizer 8 and a terminal atomized mist outlet 4.1 connected to the outside. Specifically, the sub-exhaust channel 4.9 protrudes from the edge sidewall 4.6 of the smoke treatment box 4, and the terminal atomized mist outlet 4.1 is formed at the protruding part of the sub-exhaust channel 4.9, so that the smoke and atomized gas have enough time to mix and react.

[0082] The smoke in ashtray 1 is introduced into the smoke transfer chamber by the exhaust fan 5, and reacts with negative ions generated by the negative ion emitter 3 in the vertical smoke transfer chamber 2.2 for primary purification. Then, the smoke continues to gather into the smoke filtration zone of the smoke treatment box 4. The mounting frame forms a diversion structure, and some smoke is discharged from the smoke filtration structure on the outer wall 4.3 of the smoke filtration zone under the obstruction of the mounting frame for secondary purification. The remaining smoke, which is not obstructed by the mounting frame, enters the sub-exhaust channel 4.9 at a higher flow rate, reacts with the atomized gas generated by the atomizer 8 in the sub-exhaust channel 4.9 for tertiary purification, and finally is discharged from the terminal atomized gas outlet 4.1. The smoke undergoes multiple purifications under the action of the smoke purification mechanism, which can ensure the effectiveness and reliability of smoke purification. At the same time, it can quickly and widely discharge the atomized gas with aromatherapy into the surrounding environment, which can quickly achieve air freshness in the surrounding environment.

[0083] In this embodiment, the horizontal smoke transfer chamber 2.1, the vertical smoke transfer chamber 2.2, the exhaust fan 5, and the smoke treatment box 4 are all flat structures. The atomizer 8 and the smoke filter structure are embedded in the smoke treatment box 4 from the side, which can effectively control the volume of the entire smoke extinguishing tank.

[0084] In this embodiment, the smoke treatment box 4 has horizontal ribs 4.5 and vertical ribs 4.4 formed in the atomized gas fusion zone. The horizontal ribs 4.5 and vertical ribs 4.4 extend from the outer sidewall 4.3 of the smoke treatment box 4 to its inner sidewall. The horizontal ribs 4.5, vertical ribs 4.4, bottom wall 4.8 of the smoke treatment box 4, and edge sidewall 4.6 of the smoke treatment box 4 enclose and form an installation frame. The inner opening of the installation frame is sealed by the inner sidewall of the smoke treatment box 4, and its outer opening is connected to the installation port on the outer sidewall 4.3 of the smoke treatment box 4. The atomizer 8 is installed in the installation frame after being inserted through the installation port. A sub-exhaust channel 4.9 is formed between the horizontal ribs 4.5 and the top wall 4.7 of the smoke treatment box 4.

[0085] In this embodiment, the atomizer 8 includes a housing 8.1, a fixing plate 8.2 disposed within the housing 8.1, a cotton wick 8.3 clamped and fixed by the fixing plate 8.2, an end cap covering the upper opening of the housing 8.1, and an atomizing plate 8.6 fixed to the end cap. The upper end of the cotton wick 8.3 abuts against the atomizing plate 8.6. The atomizer 8 disperses the liquid aromatherapy in the housing 8.1 through the action of the atomizing plate 8.6 to produce naturally drifting mist droplets, improving the flowability and diffusion characteristics of the aromatherapy, allowing the atomized gas to quickly diffuse into the surrounding environment to achieve air freshening.

[0086] The end cap includes an inner end cap 8.4 and an outer end cap 8.5. The inner end cap 8.4 has a groove in the middle and a through hole in the groove. The outer end cap 8.5 has an upper through hole in the middle (i.e., the aromatherapy mist outlet 8.51, which is directly connected to the middle atomizing gas outlet of the exhaust channel). The atomizing plate 8.6 is installed in the groove. The upper end of the cotton wick 8.3 passes through the lower through hole and abuts against the atomizing plate 8.6. The inner end cap 8.4 covers the upper opening of the housing 8.1. The inner end cap 8.4 and the outer end cap 8.5 cooperate to clamp and fix the atomizing plate 8.6. This detachable structure facilitates later cleaning and maintenance by the user.

[0087] The inner end cover 8.4 and the shell 8.1, as well as the outer end cover 8.5 and the inner end cover 8.4, are fixed by a snap-fit ​​structure. Specifically, the upper end face of the inner end cover 8.4 is provided with a pair of upper female snaps 8.41 and the lower end face is provided with a pair of lower male snaps 8.42. The lower end face of the outer end cover 8.5 is provided with a pair of upper male snaps. The two side walls of the shell are provided with lower female snaps 8.11. The upper male snaps and the upper female snaps 8.41 are engaged, and the lower male snaps 8.42 and the lower female snaps 8.11 are engaged.

[0088] Among them, two or more fixing plates 8.2 are arranged in a ring, and a gap is formed between adjacent fixing plates 8.2 that communicates with the inner cavity of the shell 8.1, so that the aromatherapy liquid (containing smoke decomposing agent) contained in the shell 8.1 can be adsorbed by the cotton core 8.3 and spread upward to the atomizing plate 8.6.

[0089] In this embodiment, the smoke filtration structure includes filter cotton 6 and a smoke exhaust window 7. The smoke treatment box 4 has a smoke exhaust outlet on the outer wall 4.3 of the smoke filtration zone and an annular groove around the smoke exhaust outlet. The annular groove is specifically square-ringed. The outer wall 4.3 has an inwardly extending thickened part to increase the embedding depth of the smoke exhaust window 7 frame and improve the installation stability of the smoke exhaust window 7. The smoke exhaust window 7 and the filter cotton 6 are arranged from the outside to the inside relative to the smoke exhaust outlet. The frame of the smoke exhaust window 7 is embedded in the annular groove and the filter cotton 6 is pressed onto the inner side wall of the annular groove.

[0090] In some other embodiments, the diversion structure includes a diversion plate disposed in the smoke treatment box 4, dividing the inner cavity of the smoke treatment box into an upper and lower smoke filtration zone and an atomizing gas fusion zone. The diversion plate splits the smoke entering the smoke treatment box 4 into two streams: the upper stream enters the smoke filtration zone and is filtered before exiting the smoke treatment box; the lower stream enters the atomizing gas fusion zone and reacts with the atomizing gas generated by the atomizer 8 in the atomizing gas fusion zone, undergoing three purification processes, and finally exiting from the terminal atomizing gas outlet 4.1. In this case, the atomizer 8 is not installed within the atomizing gas fusion zone, and the diversion structure is not installed on the outer wall of the smoke treatment box 4, but rather on its edge side wall.

[0091] See attached document Figure 5 A ashtray includes the aforementioned smoke purification mechanism. The smoke inlet of the horizontal smoke transfer chamber 2.1, i.e. the initial smoke inlet 2.3, is located on the front side wall of the cigarette butt disposal chamber 1.1 and extends along the width direction of the cigarette butt disposal chamber 1.1. During the ashtray extinguishing process, the top cover is closed to seal the cigarette butt disposal chamber 1.1, preventing smoke from diffusing into the surrounding environment and allowing it to be quickly discharged through the smoke inlet.
