An apparatus for purifying smoke from moxa

Abstract

This invention belongs to the field of flue gas purification technology, specifically a moxa smoke purification device. The device includes a purification unit with a housing. An air intake pipe is fixedly connected to the top of the housing. The oscillation of a swing plate guides the moxa smoke drawn into the housing, ensuring even dispersion of the smoke onto the filter cotton surface. This prevents excessively high smoke concentrations in localized areas, reduces the risk of localized clogging, and extends the overall lifespan of the filter cotton, preventing rapid performance degradation due to localized overload. Lowering the baffle rod collects temporarily stored impurities, reducing their accumulation on the filter plate and maintaining consistent permeability across the plate. Simultaneously, raising the baffle rod blocks the feed inlet, reducing airflow interference with the collection frame during pump operation. This prevents collected impurities from re-entering the purification channel due to airflow disturbances or equipment vibration, thus avoiding secondary dust generation.

Description

Technical Field

[0001] This invention belongs to the field of flue gas purification technology, specifically a device for purifying mugwort smoke. Background Technology

[0002] A moxa smoke purification device is a specialized device designed to handle the moxa smoke generated during moxibustion. During moxibustion treatment or health care, the burning of moxa sticks releases a large amount of smoke containing pollutants such as particulate matter and volatile organic compounds. This not only pollutes indoor air but can also irritate and harm the respiratory tract and eyes. The moxa smoke purification device uses specific purification technologies, such as physical filtration (using filters to intercept large particles), electrostatic adsorption (attracting tiny particles after they are charged), and activated carbon adsorption (adsorbing harmful gases and odor molecules), to effectively remove harmful substances from the moxa smoke. The purified air is then discharged, thereby improving the air quality in the moxibustion area.

[0003] In existing technologies, moxibustion smoke purification devices mainly use a fan to draw smoke-containing air into the device and use a multi-layer filtration system (such as a pre-filter layer, a HEPA high-efficiency filter layer, and an activated carbon deodorizing filter layer) to purify the smoke. The pre-filter layer intercepts larger particles, the HEPA high-efficiency filter layer filters out fine particles, and the activated carbon deodorizing filter layer adsorbs odors and harmful gases. After multiple stages of filtration, the purified air is then returned to the room. Some devices are also equipped with intelligent sensors to monitor air quality in real time and adjust the working mode to keep the air fresh during moxibustion.

[0004] The above-mentioned solutions still have some problems in practical application. Although the existing devices can complete the purification function of moxa smoke, most of the existing moxa smoke purification devices adopt direct air intake, that is, the air intake of the purification device is directly aimed at the center of the filter material. This causes the moxa smoke to impact the local area at high speed, resulting in the airflow speed in the local area being much higher than that at the edge, forming an uneven distribution of "center overload and edge idle". This uneven distribution causes the initial particles to quickly deposit in the central area, forming a dense blockage layer. However, the continuous high-speed airflow will destroy the blockage layer, enlarge the pores, and allow larger particles to pass through, forming a "screen effect", which further reduces the filtration efficiency and accelerates fiber damage, thereby reducing the service life of the filter material.

[0005] Therefore, the present invention provides a smoke purification device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a smoke purification device, which includes a purification device, the purification device including a shell, an air intake pipe fixedly connected through the top of the shell, a flow guide hood fixedly connected through one end of the air intake pipe, a filter cotton fixedly connected inside the shell, a flow guiding swing mechanism provided inside the purification device, and a moving collection mechanism provided inside the purification device. The diversion swing mechanism includes a bidirectional rack that is slidably disposed inside the housing, and the mobile collection mechanism includes a baffle rod that is slidably disposed at one end of the bidirectional rack. The baffle rod can block impurities temporarily stored inside the mobile collection mechanism when it rises, and can facilitate the entry of impurities when it falls.

[0008] Preferably, the drainage swing mechanism includes a first fixing plate, which is fixedly connected to the inner cavity sidewall of the outer shell; A bidirectional motor is fixedly connected to the side wall of the outer casing, and the output shaft of the bidirectional motor is rotatably connected through the interior of the outer casing and the first fixed plate. The output shaft of the bidirectional motor is fixedly connected to a first gear, and a bidirectional rack meshes with the outer ring surface of the first gear. The bidirectional rack is slidably connected to the side wall of the first fixed plate, and the top and bottom of the bidirectional rack are toothed.

[0009] Preferably, a second gear is engaged at the bottom of the bidirectional rack, a rotating shaft is fixedly connected to the middle of the second gear, a swing plate is fixedly connected to the outer ring surface of the rotating shaft of the second gear, and the second gear is fixedly connected to the side wall of the first fixed plate through the rotating shaft.

[0010] Preferably, the teeth of the first gear and the second gear are matched, and multiple second gears and swing plates are provided and are equidistantly distributed at the bottom of the bidirectional rack. When the bidirectional rack moves, it can drive multiple swing plates to swing simultaneously, thereby adjusting the flow direction of the smoke entering the shell.

[0011] Preferably, a rotating shaft is fixedly connected to the middle of the first gear, a cam is fixedly connected to the outer ring surface of the first gear rotating shaft, a second fixing plate is fixedly disposed on the top of the first fixing plate, a shock-absorbing material is disposed between the second fixing plate and the first fixing plate, and the second fixing plate is fixedly connected to the inner cavity side wall of the outer shell and is located above the first fixing plate.

[0012] Preferably, the second fixed plate has a first contact point fixedly connected to its side wall, a filter plate is slidably connected to its side wall, and a second contact point is fixedly connected to its side wall. Both the first and second contact points are made of elastic materials.

[0013] Preferably, the filter plate consists of two vertical plates and an inclined plate that drives the holes. The cam is located below the filter plate, and when the cam rotates, it can drive the filter plate to lift.

[0014] Preferably, the mobile collection mechanism includes a pull rope, which is fixedly connected to one end of a bidirectional rack, and the pull rope is located on the side with the lowest horizontal plane of the filter plate. One end of the pull rope is fixedly connected to an inclined block, which is slidably connected in a groove opened in the side wall of the first fixed plate and is on the same horizontal plane as the central axis of the first fixed plate.

[0015] Preferably, the inclined surface of the inclined block abuts against a blocking rod, the blocking rod being composed of a horizontal plate and a vertical rod, and the bottom of the vertical rod being adapted to the inclined surface of the inclined block; A baffle plate is fixedly connected to one side of the inclined block, and a return spring is fixedly connected to one side of the baffle plate. One end of the return spring is fixed to the inner cavity of the outer shell side wall. A collection frame is slidably connected to the outer shell side wall, and a feed port is opened on the inner cavity side wall of the outer shell.

[0016] Preferably, the vertical rod of the blocking rod slides in the inner cavity opened in the side wall of the outer shell, and the horizontal plate of the blocking rod forms an inclined surface with the feed inlet when it moves to the lowest point. The setting of the reset spring facilitates the blocking rod to block the feed inlet when the filter plate moves downward.

[0017] The beneficial effects of this invention are as follows: 1. The moxa smoke purification device of the present invention, wherein the second gear rotates with the first fixed plate via the central shaft, and the second gear meshes with the bottom of the bidirectional rack, so when the bidirectional rack moves linearly, it synchronously drives the second gear to rotate, and when the second gear rotates, it synchronously drives the swing plate fixed to it to rotate. Since the components consisting of the second gear and the swing plate are equidistantly distributed at the bottom of the bidirectional rack, when the bidirectional rack moves, it can drive multiple swing plates to rotate simultaneously. At the same time, due to the structure of the bidirectional motor, it can reverse when it rotates to a certain angle, and at the same time as reversing, it can synchronously drive multiple swing plates to rotate in the opposite direction through the bidirectional rack. The swing of the swing plates can guide the moxa smoke inhaled into the shell, so that the moxa smoke can be evenly dispersed to the surface of the filter cotton, avoiding excessively high concentration of moxa smoke in local areas, reducing the risk of local clogging of the filter cotton, thereby extending the overall service life of the filter cotton and avoiding rapid performance degradation due to local overload.

[0018] 2. In the smoke purification device of the present invention, while the filter plate moves upward, the bidirectional rack moves away from the return spring along the guide on the side of the first fixed plate. Since the pull rope is made of a non-elastic material, during the movement of the bidirectional rack, the pull rope will pull the inclined block to move linearly along the groove of the first fixed plate. Because the inclined surface at the bottom of the vertical rod of the blocking rod matches the inclined surface of the inclined block, and the blocking rod moves in the groove opened in the side wall of the outer shell, when the inclined block is pulled by the bidirectional rack, the blocking rod will move downward along the inner cavity of the side wall of the outer shell by its own weight. At this time, the return spring is in a stretched state. When the lowest end of the filter plate is flush with the feed inlet opened in the side wall of the inner cavity of the outer shell, the return spring is stretched. The side of the baffle bar abuts against the side of the baffle plate, and the top of its horizontal plate forms an inclined structure with the feed inlet. Since the air pump continues to suck in air at this time, some of the gas will carry the collected impurities along the inclined surface of the filter plate into the collection frame, thereby completing the collection of impurities blocked on the surface of the filter plate. The lowering of the baffle bar can collect the temporarily stored impurities, reducing the accumulation of impurities on the filter plate and maintaining the uniform permeability of each area of ​​the filter plate. At the same time, the raising of the baffle bar can block the feed inlet, thereby reducing the interference of airflow on the collection frame when the air pump is working, and thus preventing the collected impurities from re-entering the purification channel due to airflow disturbance or equipment vibration, avoiding the occurrence of secondary dust.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example

[0022] like Figures 1 to 8 As shown in the figure, an embodiment of the present invention provides a smoke purification device, including a purification device 1. The purification device 1 includes a housing 101, an air intake pipe 102 is fixedly connected through the top of the housing 101, a flow guide hood 103 is fixedly connected through one end of the air intake pipe 102, a filter cotton 104 is fixedly connected inside the housing 101, a flow guiding swing mechanism 2 is provided inside the purification device 1, and a moving collection mechanism 3 is provided inside the purification device 1. The diversion swing mechanism 2 includes a bidirectional rack 204 slidably disposed inside the housing 101, and the moving collection mechanism 3 includes a blocking rod 303 slidably disposed at one end of the bidirectional rack 204. The blocking rod 303 can block impurities temporarily stored inside the moving collection mechanism 3 when it rises, and can facilitate the entry of impurities when it falls.

[0023] Specifically, although existing devices can purify moxa smoke, most of them use direct-flow air intake, meaning the air inlet is directly aimed at the center of the filter material. This causes the moxa smoke to impact a local area at high speed, resulting in an airflow velocity in that area that is much higher than at the edges. This creates an uneven distribution of "overloaded center and idle edges." This uneven distribution causes particles to accumulate rapidly in the center, forming a dense blockage layer. However, continuous high-speed airflow will damage the blockage layer, enlarge the pores, and allow larger particles to pass through, creating a "screen effect." This further reduces filtration efficiency and accelerates fiber damage, thus reducing the lifespan of the filter material. Therefore, this invention solves this problem by setting a corresponding structure. The moxa smoke purification device of this invention, when it is necessary to extract moxa smoke, has the guide hood 103 placed in the moxibustion area by the operator. At this time, the air pump at the bottom of the purification device 1 is activated. The moxa smoke, influenced by the air pump, flows along the guide of the suction pipe 102 into the interior of the device and is filtered by the filter cotton 104 inside the outer shell 101. However, since most existing moxa smoke purification devices use direct-flow air intake, that is, the air inlet of the purification device is directly aimed at the center of the filter material, this causes the moxa smoke to impact the local area at high speed, leading to… The airflow velocity in this area is much higher than that at the edge, resulting in an uneven distribution of "overloaded center and idle edge". This uneven distribution causes the initial particles to quickly deposit in the central area, forming a dense blockage layer. However, the continuous high-speed airflow will destroy the blockage layer, enlarge the pores, and allow larger particles to pass through, forming a "screen effect". This further reduces the filtration efficiency and accelerates fiber damage, thereby reducing the service life of the filter material. At this time, the operation of the flow-guiding swing mechanism 2 can guide the inflow of moxa smoke, thereby improving the uniformity of the moxa smoke reaching the surface of the filter cotton 104, and thus improving the service life of the filter cotton 104. Example

[0024] like Figures 2 to 8 As shown in Example 1, another embodiment of the present invention is as follows: like Figure 4 As shown, the drainage swing mechanism 2 described in this embodiment includes a first fixing plate 201, which is fixedly connected to the inner cavity side wall of the outer shell 101. A bidirectional motor 202 is fixedly connected to the side wall of the outer shell 101, and the output shaft of the bidirectional motor 202 is rotatably connected through the interior of the outer shell 101 and the first fixing plate 201. The output shaft of the bidirectional motor 202 is fixedly connected to a first gear 203, and a bidirectional rack 204 meshes with the outer ring surface of the first gear 203. The bidirectional rack 204 is slidably connected to the side wall of the first fixed plate 201. The top and bottom of the bidirectional rack 204 are toothed. A filter plate 209 is slidably connected to the side wall of the second fixed plate 208.

[0025] like Figure 4 As shown, in this embodiment, the bottom of the bidirectional rack 204 is engaged with a second gear 205, the middle of the second gear 205 is fixedly connected to a rotating shaft, and the outer ring surface of the rotating shaft of the second gear 205 is fixedly connected to a swing plate 206.

[0026] Specifically, when the purification device 1 is working, the smoke will flow into the interior of the outer casing 101 through the suction pipe 102. At this time, the smoke will move downward under the drive of the bottom air pump. At this time, the bidirectional motor 202 fixedly connected to the side wall of the outer casing 101 will be activated. The bidirectional motor 202 will drive the first gear 203 fixed to it to rotate through its output shaft. Since the bidirectional rack 204 slides in the groove of the side wall of the first fixed plate 201 through the slider, and the first gear 203 and the bidirectional rack 204 are meshed, the rotation of the first gear 203 will drive the bidirectional rack 204 to move linearly along the guide of the groove of the side wall of the first fixed plate 201. Meanwhile, since the second gear 205 rotates with the first fixed plate 201 via the central shaft, and the second gear 205 meshes with the bottom of the double-sided rack 204, when the double-sided rack 204 moves linearly, it synchronously drives the second gear 205 to rotate. When the second gear 205 rotates, it synchronously drives the swing plate 206 fixed to it to rotate. Since the components consisting of the second gear 205 and the swing plate 206 are equidistantly distributed at the bottom of the double-sided rack 204, when the double-sided rack 204 moves, it can drive multiple swing plates 206 to rotate synchronously. The motor rotates continuously, and due to the structure of the bidirectional motor 202, it can reverse when it rotates to a certain angle. At the same time, it can drive multiple swing plates 206 to rotate in the opposite direction through the bidirectional rack 204. The swing of the swing plates 206 can guide the moxa smoke drawn into the housing 101, so that the moxa smoke can be evenly distributed to the surface of the filter cotton 104, avoiding excessively high concentration of moxa smoke in some areas, reducing the risk of local blockage of the filter cotton 104, and thus extending the overall service life of the filter cotton 104 and avoiding rapid performance degradation due to local overload.

[0027] like Figure 2 As shown, in this embodiment, a rotating shaft is fixedly connected to the middle of the first gear 203, a cam 207 is fixedly connected to the outer ring surface of the rotating shaft of the first gear 203, a second fixing plate 208 is fixedly disposed on the top of the first fixing plate 201, a shock-absorbing material is disposed between the second fixing plate 208 and the first fixing plate 201, and the second fixing plate 208 is fixedly connected to the inner cavity side wall of the outer shell 101 and is located above the first fixing plate 201.

[0028] like Figure 5 As shown, in this embodiment, the second fixing plate 208 has a first contact point 210 fixedly connected to its side wall, and the filter plate 209 has a second contact point 211 fixedly connected to its side wall. Both the first contact point 210 and the second contact point 211 are made of elastic materials.

[0029] Specifically, when the first gear 203 rotates under the drive of the bidirectional motor 202, it drives the bidirectional rack 204 to move away from the lowest side of the horizontal plane of the filter plate 209. Simultaneously, this movement drives the cam 207 to rotate synchronously via the rotating shaft. This causes the side of the cam 207 with the larger diameter to rotate. Initially, the outer ring surface of the side of the cam 207 with the smaller diameter is in contact with the bottom surface of the filter plate 209, and the filter plate 209 is not in a raised state. As the side of the cam 207 with the larger diameter gradually rotates to contact the bottom surface of the filter plate 209, it will... The filter plate 209 is pushed upward in a straight line along the groove on the side of the second fixed plate 208. During the movement, it will drive the multiple first contact points 210 fixedly connected to its side to move upward in sync. This will cause them to continuously contact the second contact points 211 fixed on the side of the second fixed plate 208, thereby generating vibration. This vibration is transmitted to the middle of the filter plate 209 through the vertical plate of the filter plate 209. Since the middle of the filter plate 209 has an inclined structure, when the filter plate 209 vibrates, it will collect the solid waste in the smoke towards the lowest end of the filter plate 209.

[0030] like Figure 7 and Figure 8 As shown, the mobile collection mechanism 3 described in this embodiment includes a pull rope 301, which is fixedly connected to one end of the bidirectional rack 204, and the pull rope 301 is located on the side with the lowest horizontal plane of the filter plate 209. One end of the pull rope 301 is fixedly connected to an inclined block 302. The inclined block 302 is slidably connected in a groove opened in the side wall of the first fixed plate 201 and is on the same horizontal plane as the central axis of the first fixed plate 201.

[0031] like Figure 8 As shown, in this embodiment, the inclined surface of the inclined block 302 abuts against the blocking rod 303, which is composed of a horizontal plate and a vertical rod, and the bottom of the vertical rod is adapted to the inclined surface of the inclined block 302; A baffle plate 304 is fixedly connected to one side of the inclined block 302, and a return spring 305 is fixedly connected to one side of the baffle plate 304. One end of the return spring 305 is fixed to the inner cavity of the side wall of the outer shell 101. A collection frame 306 is slidably connected to the side wall of the outer shell 101, and a feed port is opened on the side wall of the inner cavity of the outer shell 101.

[0032] Specifically, as the filter plate 209 moves upward, the bidirectional rack 204 moves away from the return spring 305 along the guide on the side of the first fixed plate 201. Since the pull rope 301 is made of a non-elastic material, during the movement of the bidirectional rack 204, it pulls the inclined block 302 to move linearly along the groove of the first fixed plate 201. Because the inclined surface at the bottom of the vertical rod of the blocking rod 303 matches the inclined surface of the inclined block 302, and the blocking rod 303 moves within the groove on the side wall of the outer casing 101, when the inclined block 302 is pulled by the bidirectional rack 204, the blocking rod 303 moves downward along the inner cavity of the side wall of the outer casing 101 by its own weight. At this time, the return spring 305 is in a stretched state. When the lowest point of the filter plate 209 is aligned with the groove on the side wall of the inner cavity of the outer casing 101... When the feed inlet is flush with the feed inlet, the side of the baffle bar 303 will abut against the side of the baffle plate 304, and the top of its horizontal plate will form an inclined structure with the feed inlet. Since the air pump will continue to suck air at this time, some of the gas will carry the collected impurities into the collection frame 306 along the inclined surface of the filter plate 209, thereby completing the collection of impurities blocked on the surface of the filter plate 209. The lowering of the baffle bar 303 can collect the temporarily stored impurities and reduce the accumulation of impurities on the filter plate 209, thereby maintaining the uniform permeability of each area of ​​the filter plate 209. At the same time, the rising of the baffle bar 303 can block the feed inlet, thereby reducing the interference of the airflow on the collection frame 306 when the air pump is working, and thus preventing the collected impurities from re-entering the purification channel due to airflow disturbance or equipment vibration, avoiding the occurrence of secondary dust.

[0033] Working principle: When the purification device 1 is working, the smoke will flow into the interior of the outer shell 101 through the suction pipe 102. At this time, the smoke will move downward under the drive of the bottom air pump. At this time, the bidirectional motor 202 fixedly connected to the side wall of the outer shell 101 will be activated. The bidirectional motor 202 will drive the first gear 203 fixed thereto to rotate through its output shaft. Since the bidirectional rack 204 slides in the groove of the side wall of the first fixed plate 201 through the slider, and the first gear 203 and the bidirectional rack 204 are meshed, the rotation of the first gear 203 will drive the bidirectional rack 204 to move linearly along the guide groove of the side wall of the first fixed plate 201. Meanwhile, since the second gear 205 rotates with the first fixed plate 201 via the central shaft, and the second gear 205 meshes with the bottom of the double-sided rack 204, when the double-sided rack 204 moves linearly, it synchronously drives the second gear 205 to rotate. When the second gear 205 rotates, it synchronously drives the swing plate 206 fixed to it to rotate. Since the components consisting of the second gear 205 and the swing plate 206 are equidistantly distributed at the bottom of the double-sided rack 204, when the double-sided rack 204 moves, it can drive multiple swing plates 206 to rotate synchronously. The motor rotates continuously, and due to the structure of the bidirectional motor 202, it can reverse when it rotates to a certain angle. At the same time, it can drive multiple swing plates 206 to rotate in the opposite direction through the bidirectional rack 204. The swing of the swing plates 206 can guide the moxa smoke drawn into the housing 101, so that the moxa smoke can be evenly distributed to the surface of the filter cotton 104, avoiding excessively high concentration of moxa smoke in some areas, reducing the risk of local blockage of the filter cotton 104, and thus extending the overall service life of the filter cotton 104 and avoiding rapid performance degradation due to local overload.

[0034] When the first gear 203 rotates under the drive of the bidirectional motor 202, it drives the bidirectional rack 204 to move away from the lowest side of the horizontal plane of the filter plate 209. Simultaneously, this movement drives the cam 207 to rotate synchronously via the rotating shaft. This causes the side of the cam 207 with the larger diameter to rotate. Initially, the outer ring surface of the side of the cam 207 with the smaller diameter is in contact with the bottom surface of the filter plate 209, and the filter plate 209 is not in a raised state. As the side of the cam 207 with the larger diameter gradually rotates to contact the bottom surface of the filter plate 209, it will synchronously... The filter plate 209 is pushed to move upward in a straight line along the groove on the side of the second fixed plate 208. During the movement, it will drive the multiple first contact points 210 fixedly connected to its side to move upward synchronously. This will cause it to continuously contact the second contact points 211 fixed on the side of the second fixed plate 208, thereby generating vibration. This vibration is transmitted to the middle of the filter plate 209 through the vertical plate of the filter plate 209. Since the middle of the filter plate 209 has an inclined structure, when the filter plate 209 vibrates, it will collect the solid waste in the smoke towards the lowest end of the filter plate 209.

[0035] As the filter plate 209 moves upward, the bidirectional rack 204 moves away from the return spring 305 along the guide on the side of the first fixed plate 201. Since the pull rope 301 is made of non-elastic material, during the movement of the bidirectional rack 204, it pulls the inclined block 302 to move linearly along the groove of the first fixed plate 201. Because the inclined surface at the bottom of the vertical rod of the blocking rod 303 matches the inclined surface of the inclined block 302, and the blocking rod 303 moves within the groove on the side wall of the outer casing 101, when the inclined block 302 is pulled by the bidirectional rack 204, the blocking rod 303 moves downward along the inner cavity of the side wall of the outer casing 101 by its own weight. At this time, the return spring 305 is in a stretched state. When the lowest point of the filter plate 209 is aligned with the feed inlet on the side wall of the inner cavity of the outer casing 101... When the two sides are aligned, the side of the baffle bar 303 will abut against the side of the baffle plate 304, and the top of its horizontal plate will form an inclined structure with the feed inlet. Since the air pump will continue to suck air at this time, some of the gas will carry the collected impurities into the collection frame 306 along the inclined surface of the filter plate 209, thereby completing the collection of impurities blocked on the surface of the filter plate 209. The lowering of the baffle bar 303 can collect the temporarily stored impurities and reduce the accumulation of impurities on the filter plate 209, thereby maintaining the uniform permeability of each area of ​​the filter plate 209. At the same time, the rising of the baffle bar 303 can block the feed inlet, thereby reducing the interference of the airflow on the collection frame 306 when the air pump is working, and thus preventing the collected impurities from re-entering the purification channel due to airflow disturbance or equipment vibration, avoiding the occurrence of secondary dust.
