Description

Technical Field

[0001] The present invention relates to the technical field of air purification devices, and in particular to an indoor air purification device. Background Art

[0002] An air purifier is a device designed to improve indoor air quality by absorbing, decomposing or transforming various pollutants in the air, such as PM2.5, dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, viruses and allergens, etc. Air purifiers are widely used in indoor environments such as homes, offices, hospitals, schools and public places.

[0003] The filter plate is a key component in the air purification device for filtering pollutants in the air. The maintenance and replacement of the filter plate is essential to maintaining the efficiency of the air purifier. In order to avoid clogging of the filter plate and affecting the purification effect, the filter plate needs to be cleaned frequently.

[0004] In the prior art, the filter plate is generally detachably built into the air purification device so that it can be removed for cleaning. For example, the patent with the authorization announcement number CN211358070U discloses an air purification device that is easy to remove the filter plate. The device includes a housing, a socket is provided at the midpoint of the top of the housing, a fixing plate is provided at the midpoint of the top of the housing, the bottom of the fixing plate is in contact with the top of the housing, and the filter plate is fixedly connected at the midpoint of the bottom of the fixing plate. In this device, when the filter plate is blocked, it is necessary to manually remove the filter plate through some operating steps, and then take it to the outside of the air purification device for cleaning. After cleaning, the filter plate must be manually assembled into the air purification device, which is troublesome to operate and takes a long time. Summary of the invention

[0005] The present invention provides an indoor air purification device to solve the technical problem that the filter plate in the air purification device in the prior art needs to be manually removed for cleaning, the manual participation process is relatively large, and the operation steps are relatively complicated.

[0006] In order to solve the above problems, the present invention provides an indoor air purification device adopting the following technical solutions:

[0007] An indoor air purification device comprises a shell, a fan and a filter plate, wherein the top of the shell is provided with an air inlet, and the bottom is provided with an air outlet; the fan is installed in the shell and is located below the air inlet; the filter plate is installed in the shell and is located below the fan; two vertically arranged partition plates are provided in the shell, the two partition plates are located below the fan and are arranged at intervals from left to right, and the partition plates divide the inner cavity of the shell into a filter cavity and two energy storage cavities located on the left and right sides of the filter cavity respectively; the filter plate comprises an upper filter plate and a lower bracket parallel to each other, and a first elastic member is connected between the upper filter plate and the lower bracket; a first locking structure for horizontally locking the filter plate on the partition plate is provided on the filter plate, and the first locking structure is unlocked when the upper filter plate moves toward the lower bracket. The filter plate can be flipped downward with the rotating shaft; a rotating shaft extending in the left and right directions is fixedly connected to one side of the lower bracket, and the left and right ends of the rotating shaft are respectively rotatably mounted on two partition plates, and the end of the rotating shaft extends into the energy storage chamber and is sleeved with a blade wheel on the outside, and a torsion spring is connected between the blade wheel and the rotating shaft, and the blade wheel is used to be rotated by the wind entering the energy storage chamber, thereby driving the torsion spring to twist and store energy, and the torsion spring is used to release energy when the first locking structure is unlocked to drive the rotating shaft to rotate and drive the filter plate to flip downward; the end of the rotating shaft is also connected to a reset mechanism for driving the rotating shaft to reverse after the rotating shaft rotates a set angle to drive the filter plate to reset to a horizontal state; a friction block protruding toward the filter chamber is provided on the partition plate, and the friction block is located below the filter plate and on the flipping path of the filter plate.

[0008] With the above technical solution, the wind blown in by the fan enters the filter chamber and the energy storage chamber respectively. The wind entering the energy storage chamber drives the blade wheel to rotate, causing the torsion spring to twist and store energy. When the upper filter plate is seriously blocked and needs to be cleaned, the wind blown into the filter chamber by the fan cannot pass through the upper filter plate. The upper filter plate moves toward the lower bracket under the action of wind pressure, so that the first locking structure is unlocked. At this time, the torsion spring releases the elastic force, drives the rotating shaft to rotate, and the rotating shaft drives the filter plate to flip downward. In the process of flipping the filter plate from the horizontal state to the vertical state, the friction block on the partition plate slows down the speed of the filter plate rotating downward, so that the filter plate stays in the inclined state for a long time. During this period of time, the wind sucked in by the fan passes through the inclined upper filter plate to blow away the impurities stuck on the surface of the upper filter plate. When the filter plate flips at an obtuse angle, the wind blown into the filter chamber by the fan can blow to the bottom surface of the upper filter plate, recoil the upper filter plate, and better blow away the impurities stuck in the upper filter plate.

[0009] By adopting the device, the filter plate can be cleaned without removing the filter plate from the casing, and when the filter plate is blocked, it can be cleaned automatically without manual participation, and the cleaning process is more time-saving and labor-saving.

[0010] Furthermore, the filter plates are provided with two pieces, and the two filter plates are symmetrically installed between the two partition plates in the front and rear directions. The two lower brackets are respectively fixedly connected with rotating shafts on one side close to each other, and the left and right ends of the two rotating shafts are respectively extended into the two energy storage chambers and are connected with the torsion springs, the blade wheels and the reset mechanism; a horizontally arranged baffle is provided between the filter plate and the fan, and the baffle is slidably assembled on the shell in the front and rear directions, and a baffle driving mechanism is provided on the shell, and the baffle driving mechanism is used to drive the baffle to reciprocate in the front and rear directions to alternately cover the two filter plates; the filter plate is also provided with a second locking structure for locking the filter plate on the partition plate when the filter plate is flipped downward at a set obtuse angle, and when the upper filter plate moves with its back toward the lower bracket, the second locking structure locks the filter plate on the partition plate, and when the upper filter plate moves toward the lower bracket, the second locking structure is unlocked.

[0011] With the above technical solution, two filter plates are provided, and the baffle can be moved in the front-to-back direction so that the two filter plates can be exposed alternately, so that the two filter plates can perform filtering work alternately, thereby extending the service life of the equipment. When one of the filter plates is blocked, the filter plate can be flipped to the bottom of the other filter plate after rotating at a set obtuse angle, and the wind sucked in by the fan is blown from the other filter plate to the blocked upper filter plate. The upper filter plate moves back to the lower bracket under the action of gravity and wind pressure, so that the second locking structure locks the filter plate between the two partition plates. At this time, the wind sucked in by the fan continuously blows to the upper filter plate, and the impurities in the upper filter plate are blown away in the opposite direction for a long time, and the cleaning effect is better.

[0012] Furthermore, the first locking structure includes a first slider, two first connecting rods and two first slide plates, the first slider is guided and slidably assembled on the lower bracket along the front and rear directions, a second elastic member is pressed between the first slider and the lower bracket, the two first slide plates are respectively arranged on the left and right sides of the first slider, and the two first slide plates are guided and slidably assembled on the lower bracket along the left and right directions, the two first connecting rods are respectively obliquely connected between the first slider and the two first slide plates, and the two ends of the first connecting rod are respectively hinged to the first slider and the first slide plate; a horizontal support groove is provided on the partition plate, and the back ends of the two first slide plates are respectively inserted into the horizontal support grooves of the two partition plates; a lower push inclined surface is provided on the top of the first slider, and an upper push inclined surface is provided on the bottom of the upper filter plate that fits the lower push inclined surface. When the upper filter plate moves toward the lower bracket, the first slider is pushed to move back to the first slider by the upper push inclined surface and the lower push inclined surface, thereby driving the two first slide plates to approach each other to disengage from the horizontal support groove.

[0013] By adopting the above technical solution, when the upper filter plate moves toward the lower bracket, the upper push slope pushes the lower push slope, so that the first slider moves toward the rotating shaft, and the first slider pulls the two first sliders closer to each other through the first connecting rod, so that the first slider is disengaged from the horizontal support groove on the partition plate, thereby unlocking the first locking structure, and the rotating shaft can rotate to drive the filter plate to flip.

[0014] Furthermore, the second locking structure includes a second slider, a pull plate, two second pull rods and two second sliders. The second slider is guided and slidably assembled on the lower bracket along the front-back direction. The pull plate is obliquely connected between the upper filter plate and the second slider. Both ends of the pull plate are hinged to the upper filter plate and the second slider respectively. The two second sliders are respectively arranged on the left and right sides of the second slider. The two second sliders are both guided and slidably assembled on the lower bracket along the left and right directions. The two second connecting rods are respectively connected between the second slider and the two second sliders, and the two ends of the second connecting rods are respectively hinged to the second slider and the second slider; an inclined support groove is provided on the partition plate obliquely below the horizontal support groove. When the upper filter plate moves with its back toward the lower bracket, the second slider is pulled toward the second slider by the pull plate, and the movement drives the two second sliders to move away from each other so as to be inserted into the inclined support groove.

[0015] When the filter plate is rotated to the inclined support groove, the second slide plate can be inserted into the inclined support groove, and the second locking structure locks the filter plate at this position, and the wind sucked in by the fan can continuously recoil the upper filter plate. After the impurities on the surface of the upper filter plate are blown off, the wind sucked in by the fan can pass through the upper filter plate, and the wind pressure on the upper filter plate is reduced. At this time, the upper filter plate moves toward the lower bracket under the action of the first elastic member, and the pull plate flips in the opposite direction, driving the second slide plate to move toward the rotating shaft, the two second slide plates approach each other, and the second locking structure is unlocked.

[0016] Furthermore, a discharge frame is provided in the shell, and the discharge frame is located between the two partition plates, and the left and right outer walls of the discharge frame are respectively fitted with the two partition plates, and a gap is provided between the front and rear side walls of the discharge frame and the front and rear inner walls of the shell, and the space in the gap forms an exhaust chamber, and the inner cavity of the discharge frame forms a discharge chamber; two discharge plates are respectively obliquely and slidably inserted on the front and rear side walls of the discharge frame, and the two discharge plates approach each other from top to bottom, and the top ends of the front and rear side walls of the discharge frame are hinged with sealing plates, which are located in the exhaust chamber, and the top of the discharge plate is abutted against the bottom surface of the sealing plate, and when the sealing plate is rotated to a horizontal position, the exhaust chamber can be blocked, and a magnet is slidably installed in the discharge frame along the up and down directions, and the magnet is connected to the two discharge plates, and a magnetic block is connected to the end of the lower bracket away from the rotating shaft.

[0017] By adopting the above technical scheme, when the air purifier is in normal working state, the bottoms of the two discharge plates contact each other to seal the discharge cavity, the sealing plate is in an inclined state, and the gas sucked by the fan enters the exhaust cavity and is discharged from the air outlet. When the filter plate is blocked, the filter plate swings downward, and the magnetic block on the filter plate approaches the magnet. The magnetic block generates an upward magnetic attraction to the magnet, driving the magnet to move upward, and the magnet drives the two discharge plates to slide upward at an angle. The bottom ends of the two discharge plates are separated from each other, and the top end of the discharge plate pushes the sealing plate to rotate the sealing plate to a horizontal state, thereby sealing the exhaust cavity. The impurities blown off the filter plate will fall between the two discharge plates and fall into the discharge cavity from between the two discharge plates, thereby preventing the blown impurities from being discharged from the air outlet and polluting the air.

[0018] Furthermore, the reset mechanism includes a first gear, a second gear, a sliding ring, an arcuate slide and a driving ring, the first gear is fixedly mounted on the rotating shaft, the second gear is rotatably mounted on the rotating shaft, the first gear is located on the side close to the partition plate, and the second gear is transmission-connected to the end of the rotating shaft to drive the rotating shaft to reverse when the second gear rotates; the sliding ring is slidingly mounted on the first gear, and a sliding tooth for being inserted into the tooth groove of the first gear is provided in the sliding ring, and a guide rod is connected to the outer side of the sliding ring; the arcuate slide is provided on the partition plate, and the side of the arcuate slide facing away from the partition plate is an inclined push surface, and the guide rod is abutted against the push surface, the driving ring is slidingly mounted on the first gear and is located on the side of the sliding ring facing away from the partition plate, and a driving tooth for being inserted into the tooth groove in the first gear or the second gear is provided on the inner side of the driving ring, and a third elastic member is pressed between the driving ring and the shell, and the third elastic member is used to apply an elastic force toward the partition plate to the driving ring, and one end of the torsion spring is connected to the outer side wall of the driving ring.

[0019] With the above technical solution, when the first locking structure is unlocked, the torsion spring with over-energy drives the drive ring to rotate, the drive ring drives the first gear to rotate, and thus drives the rotating shaft to rotate, the rotating shaft drives the filter plate to swing downward, the sliding ring also rotates while the first gear rotates, the push surface of the arc slide pushes the guide rod to drive the sliding ring to move toward the second gear, the sliding ring pushes the drive ring to move toward the second gear, the drive ring moves to the second gear, drives the second gear to rotate, the second gear drives the rotating shaft to reverse, and drives the filter plate to swing in the opposite direction to the initial horizontal position. Since the sliding ring also reverses while the rotating shaft reverses, the guide rod gradually moves to the lower part of the push surface, and the third elastic member can push the driving ring and the sliding ring to move toward the partition plate, thereby realizing the reset of the sliding ring and the driving ring.

[0020] Furthermore, the driving ring includes an annular shell and a movable ring. The movable ring is slidably assembled inside the annular shell along the left and right directions. The inner wall of the movable ring is connected with driving teeth. The movable ring and the annular shell are non-rotatably connected. The left and right sides of the annular shell are each provided with an annular baffle. The inner wall of the annular baffle is connected with a fourth elastic member. A spacing is provided between the fourth elastic member and the movable ring.

[0021] With the above technical solution, when the moving ring switches between the first gear and the second gear, the driving teeth often cannot be directly aligned with the tooth grooves on the other gear, but first contact the side wall of the other gear, and then rotate until the driving teeth are aligned with the tooth grooves in the other gear to complete the switching. By setting a fourth elastic member between the moving ring and the annular baffle, a certain buffering effect can be exerted on the moving ring when the moving ring collides with the side wall of the other gear, thereby preventing the moving ring from being damaged. There is a gap between the fourth elastic member and the moving ring. After the entire driving ring is pushed onto the second gear, the annular shell needs to move toward the first gear for an idle stroke first, so that the fourth elastic member can contact the moving ring before pushing the moving ring toward the first gear. In this way, the moving ring can stay on the second gear for a long period of time, so that the rotating shaft has sufficient time to reverse to drive the filter plate to flip back to a horizontal position.

[0022] Furthermore, the end of the second gear facing away from the first gear is connected to a first face gear, the first face gear is rotatably mounted on a rotating shaft, the end of the rotating shaft is fixedly connected to a second face gear, the meshing teeth of the first face gear and the second face gear are arranged opposite to each other, a support frame is fixedly connected to the housing, the support frame is mounted on the outside of the second face gear, a transmission gear is rotatably mounted on the support frame, and the transmission gear is meshed with the first face gear and the second face gear.

[0023] By adopting the above technical solution, when the second gear rotates, it drives the first face gear to rotate, when the first face gear rotates, it drives the transmission gear to rotate, the transmission gear drives the second face gear to rotate, and the second face gear drives the rotating shaft to rotate. The rotation direction of the second face gear is opposite to that of the first face gear, so that when the second gear rotates, it can drive the rotating shaft to rotate in the opposite direction.

[0024] Furthermore, each of the two partition plates is provided with an arc-shaped slide groove, and the two arc-shaped slide grooves are respectively located below the two filter plates. The friction block is slidably assembled in the arc-shaped slide groove along the extension direction of the arc-shaped slide groove. The groove wall of the arc-shaped slide groove is provided with a guide groove inclined from bottom to top toward the other partition plate. The side wall of the friction block is provided with a guide block, and the guide block is inserted in the guide groove. A fifth elastic member is pressed between the friction block and the groove wall of the arc-shaped slide groove.

[0025] By adopting the above technical solution, when the filter plate is rotated back to a horizontal position after cleaning, when the filter plate passes through the friction block, it will push the friction block to move back to the other partition plate, causing the friction block to shrink to the inner side of the corresponding partition plate, thereby reducing the friction force on the filter plate and avoiding affecting the resetting of the filter plate.

[0026] Furthermore, an inclined guide plate is connected above the partition plate, and the guide plate is used to guide the wind sucked by the fan toward the energy storage chamber.

[0027] The beneficial effect provided by the present invention is that more wind can be guided to the energy storage chamber by setting the guide plate, so that the wind pressure in the energy storage chamber is large enough to drive the torsion spring to store energy when the blade wheel rotates.

[0028] The beneficial effect of an indoor air purification device provided by the present invention is that when the filter plate is blocked, the first locking structure is automatically unlocked, and the torsion spring releases energy to drive the filter plate to flip to an inclined position, so that the wind sucked in by the fan can directly blow away the impurities on the inclined filter plate, and the filter plate can also be flipped at a set obtuse angle to rotate under another filter plate, so that the wind sucked in by the fan can recoil the filter plate and blow away the impurities on the surface of the filter plate. The filter plate can be automatically cleaned when it is blocked, and there is no need to remove the filter plate for cleaning. The cleaning process does not require manual participation, which is more time-saving and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0047] The following is one embodiment of an indoor air purification device provided by the present invention:

[0048] like Figure 1-Figure 4 As shown, an indoor air purification device includes a shell 1, a fan 2, a partition plate 3, a filter plate, a baffle 6, a baffle driving mechanism 14, a first locking structure, a second locking structure, a reset mechanism, a torsion spring 16, a blade wheel 15, a friction block 8, a collection frame 10, a sealing plate 11, a discharge plate 12, a magnetic block and a magnet 9.

[0049] like Figure 1 As shown, the shell 1 is in the shape of a quadrangular prism, an air inlet 101 is arranged on the top surface of the shell 1, an air outlet 102 is arranged at the bottom of the side walls around the shell 1, and a moving wheel 103 is connected to each of the four corners of the bottom of the shell 1.

[0050] like Figure 2 , Figure 3 As shown, the fan 2 is located in the inner cavity of the housing 1 and below the air inlet 101 . The fan 2 is used to draw external air into the inner cavity of the housing 1 through the air inlet 101 .

[0051] like Figure 2 As shown, there are two partition plates 3, which are arranged symmetrically inside the housing 1, and there is a gap between the partition plates 3 and the side wall of the housing 1. The two partition plates 3 divide the inner cavity of the housing 1 into a filter cavity 105 and two energy storage cavities 104 located on the left and right sides of the filter cavity 105. The upper parts of the two partition plates 3 are connected with inclined guide plates 7, and the two guide plates 7 are away from each other from top to bottom. Figure 8 As shown, each partition plate 3 is provided with two horizontal support grooves 303 arranged at intervals in front and back, and two inclined support grooves 304 arranged at intervals in front and back, the two inclined support grooves 304 are symmetrical in front and back, and the two inclined support grooves 304 are respectively located below the two horizontal support grooves 303. Figure 4 , Figure 8 As shown, each of the two partition plates 3 is provided with an arc-shaped slide groove 301, and the arc-shaped slide groove 301 is located below the horizontal support groove 303. The arc-shaped slide groove 301 on one of the partition plates 3 is located on the front half of the partition plate 3, and the arc-shaped slide groove 301 on the other partition plate 3 is located on the back half of the partition plate 3.

[0052] like Figure 3As shown, there are two filter plates, which are arranged symmetrically front and back. The filter plates include an upper filter plate 4 and a lower bracket 5 which are parallel to each other. The upper filter plate 4 is provided with a filter hole, and the lower bracket 5 is provided with a ventilation channel which is much larger than the filter hole, so as not to affect the wind passing through the upper filter plate 4 to pass through the lower bracket 5. The ventilation channel is not shown in the figure. Fig.10 As shown, the bottom of the upper filter plate 4 is connected with an upper pressing block 28, the bottom surface of which is an inclined upper push slope, and a plurality of first elastic members 27 are connected between the upper filter plate 4 and the lower bracket 5, the first elastic members 27 being springs that can be extended and retracted in a direction perpendicular to the filter plate. A rotating shaft 17 extending in the left-right direction is fixedly connected to the side close to each other on the two lower brackets 5, and the two ends of the rotating shaft 17 are respectively rotatably mounted on the two partition plates 3, and the opposite ends of the two rotating shafts 17 are respectively extended into the two energy storage chambers 104.

[0053] like Figure 2 , Figure 3 As shown, the area and shape of the baffle 6 are the same as those of the filter plate. The baffle 6 is guided and slidably assembled between the two partition plates 3 along the front-rear direction and is located between the fan 2 and the filter plate.

[0054] like Figure 2 , Figure 3 As shown, the baffle driving mechanism 14 adopts a screw nut transmission structure, and the baffle driving mechanism 14 is used to drive the baffle 6 to move back and forth in the front and rear directions so that the two filter plates work alternately. Before the blocked filter plate swings down to a vertical state, the baffle 6 is always located above the other unused filter plate, so that the wind can blow to the upper surface of the blocked filter plate. When the blocked filter plate rotates to a vertical state, the baffle driving mechanism 14 drives the baffle 6 to move above the initial position of the blocked baffle 6, so that the wind sucked by the fan 2 can start to blow from the unblocked filter plate to the bottom of the blocked filter plate.

[0055] like Fig.11 As shown, the first locking structure is provided with two groups, which are respectively installed on two filter plates. The first locking structure includes a first sliding block 30 , a first connecting rod 35 and a first sliding plate 34 .

[0056] like Fig.11 As shown, the first slider 30 is guided and slidably assembled on the lower bracket 5 along the front-back direction, and a lower push inclined surface 3001 is provided on the top of the first slider 30, which is inclined from top to bottom and away from the rotating shaft 17, and the upper push inclined surface is in contact with the lower push inclined surface 3001. A second elastic member 29 is pressed between the lower bracket 5 and the first slider 30, and the second elastic member 29 is used to apply an elastic force to the first slider 30 away from the rotating shaft 17.

[0057] like Fig.12As shown, there are two first slide plates 34, both of which extend in the left-right direction and are guided and slidably assembled on the lower bracket 5 in the left-right direction. Both of the first slide plates 34 are located on the side of the first slider 30 facing away from the rotating shaft 17 and are respectively arranged on the left and right sides of the first slider 30.

[0058] like Fig.12 As shown, two first connecting rods 35 are provided, one end of each of the two first connecting rods 35 is hinged to one end of the first sliding block 30 facing away from the rotating shaft 17 , and the other ends of the two connecting rods are hinged to the two first sliding plates 34 respectively.

[0059] When the filter plate is in a horizontal state, the first elastic member 27 is not subjected to external force, and the two first slide plates 34 are both extended out of the lower bracket 5 and correspondingly inserted into the two horizontal insertion holes on the two partition plates 3 that are opposite to each other, so that the filter plate is horizontally locked between the two partition plates 3 by the first locking structure. When the filter plate is blocked, the upper filter plate 4 moves toward the lower bracket 5 under the action of wind pressure, and the upper push inclined surface pushes the lower push inclined surface 3001 to drive the first slider 30 to move toward the rotating shaft 17. The first slider 30 pulls the two first sliders 30 closer to each other through the two first connecting rods 35, so that the first slider 30 is separated from the partition plate 3, and the first locking structure is unlocked.

[0060] like Fig.11 As shown, the second locking structure is provided with two groups, which are respectively installed on two filter plates. The second locking structure includes a second slider 32 , a pull plate 31 , a second pull rod and a second slider 32 .

[0061] like Fig.11 As shown, the second slider 32 is guided and slidably assembled on the lower bracket 5 along the front-rear direction, and the two ends of the pull plate 31 are respectively hinged to the upper filter plate 4 and the second slider 32 , and an angle is formed between the pull plate 31 and the lower bracket 5 with the opening facing away from the rotating shaft 17 .

[0062] like Fig.12 As shown, there are two second slide plates 33, both of which extend in the left-right direction and are guided and slidably assembled on the lower bracket 5 in the left-right direction. Both of the second slide plates 33 are located on the side of the second slider 32 facing away from the rotating shaft 17 and are respectively arranged on the left and right sides of the second slider 32.

[0063] like Fig.12 As shown, two second connecting rods 36 are provided, one end of each of the two second connecting rods 36 is hinged to one end of the second sliding block 32 facing away from the rotating shaft 17 , and the other ends of the two connecting rods are hinged to the two second sliding plates 33 respectively.

[0064] When the filter plate is in the horizontal state and flipped downward to the vertical state, the ends of the two second slide plates 33 are both received in the lower bracket 5, and the second locking structure is in the unlocked state. When the filter plate flips downward to the point where the upper filter plate 4 begins to be located below the lower bracket 5, the upper filter plate 4 moves back toward the lower bracket 5 under the action of its own weight and wind pressure, driving the pull plate 31 to rotate, and the pull plate 31 drives the second slide block 32 to move toward the second slide plate 33, so that the two second slide plates 33 are separated from each other, so that the second slide plate 33 can be pressed against the partition plate 3. When the filter plate rotates to set an obtuse angle, the two second slide plates 33 move to the two opposite oblique support grooves on the two partition plates 3 and are stuck in the oblique support grooves. At this time, the second locking structure locks the filter plate at this position.

[0071] When the second gear 21 rotates, the first face gear 20 , the transmission gear 19 , and the second face gear 18 drive the rotating shaft 17 to rotate in the opposite direction relative to the second gear 21 .

[0072] like Fig.14 As shown, the sliding ring 25 is slidably mounted on the first gear 37 , a guide rod 26 is connected to the outer wall of the sliding ring 25 , a sliding tooth is provided on the inner wall of the sliding ring 25 , and the sliding tooth is inserted in the tooth groove of the first gear 37 , and the sliding plate can slide left and right on the first gear 37 .

[0073] like Figure 7 As shown, there are two arc-shaped slideways 24, both of which are arranged on the partition plate 3 and coaxially arranged on the outer side of the sliding ring 25. The two arc-shaped slideways 24 are arranged symmetrically with respect to the center, and the side of the arc-shaped slideway 24 facing away from the partition plate 3 is a push surface 2401 inclined along the arc-shaped extension direction of the arc-shaped slideway 24, and the guide rod 26 is pressed against the push surface 2401 to push the guide rod 26 when the arc-shaped slideway 24 rotates.

[0074] like Fig.14 As shown, the driving ring is slidably mounted on the first gear 37 and is located on the side of the sliding ring 25 facing away from the partition plate 3 . The driving ring includes an annular housing 38 and a moving ring 40 .

[0075] A guide slot extending in the left-right direction is provided on the inner side wall of the annular shell 38 . An annular baffle 39 is provided on each of the left and right sides of the annular shell 38 . The annular baffle 39 is mounted on the first gear 37 . A fourth elastic member 41 is connected to the inner side wall of the annular baffle 39 .

[0076] The moving ring 40 is sleeved on the first gear 37 and coaxially penetrated inside the annular housing 38. The moving ring 40 is located between the fourth elastic members 41 on the two annular baffles 39, and a gap is provided between the moving ring 40 and the fourth elastic member 41. A slider is provided on the outer wall of the moving ring 40, and the slider is inserted into the guide groove, so that the moving ring 40 can be slidably assembled in the annular housing 38 along the left and right directions and can be anti-rotatingly matched with the annular housing 38. The inner wall of the moving ring 40 is connected with a driving tooth, which can be inserted into the tooth groove in the first gear 37 or the second gear 21. The width dimension of the moving ring 40 is smaller than the spacing dimension between the first gear 37 and the second gear 21, so as to avoid the moving ring 40 from getting stuck when switching between the first gear 37 and the second gear 21.

[0077] The third elastic member 22 is press-fitted between the driving ring and the supporting frame. The third elastic member 22 is used to apply an elastic force to the driving ring to move toward the partition plate 3 .

[0078] like Figure 5As shown, the torsion spring 16 is a spiral wire torsion spring 16 , and the inner end of the torsion spring 16 is fixedly connected to the outer side wall of the annular housing 38 .

[0079] The blade wheel 15 is sleeved on the outer side of the torsion spring 16 , and the outer end of the torsion spring 16 is fixedly connected to the blade wheel 15 .

[0080] like Figure 4 , Fig. 9 As shown, there are two friction blocks 8, and the sides of the two friction blocks 8 that are close to each other are both protruding from the corresponding partition plate 3. The two friction blocks 8 are respectively slidably assembled in the above-mentioned arc-shaped slide groove 301, and the fifth elastic member 23 is pressed between the friction block 8 and the groove wall of the arc-shaped slide groove 301. The groove wall of the arc-shaped slide groove 301 is provided with a guide groove 302 that is inclined from bottom to top and back to the other partition plate 3, and the side wall of the friction block 8 is provided with a guide block, which is inserted into the guide groove 302. When the filter plate is turned down, it contacts with the friction block 8, the friction force it is subjected to increases, and the overall turning speed is slowed down.

[0081] like Figure 3 , Figure 4 , Figure 8 As shown, the aggregate frame 10 is located between the two partition plates 3, the left and right outer walls of the aggregate frame 10 are respectively in contact with the two partition plates 3, a gap is provided between the front and rear outer walls of the aggregate frame 10 and the front and rear inner walls of the shell 1, the area within the gap forms an exhaust cavity, and the inner cavity of the aggregate frame 10 forms a discharge cavity.

[0082] like Figure 8 As shown, there are two sealing plates 11, which are respectively hinged at the top ends of the front and rear side walls of the collecting frame 10. The sealing plates 11 are located in the exhaust cavity. When the sealing plates 11 are rotated to a horizontal position, the exhaust cavity can be blocked.

[0083] like Figure 8 As shown, there are two discharge plates 12, both of which are arranged obliquely, and the two discharge plates 12 are close to each other from top to bottom, and the two discharge plates 12 are respectively slidably installed on the front and rear side walls of the collection frame 10 along their own oblique directions. The top of the discharge plate 12 is connected to a vertical connecting plate 13, and the top of the connecting plate 13 is against the bottom surface of the sealing plate 11.

[0084] There are two magnetic blocks, which are respectively connected to one end of the two lower brackets 5 facing away from the rotating shaft 17.

[0085] like Figure 8 As shown, the magnet 9 is arc-shaped and is located between two vertical support plates. The magnet 9 is guided and slidably assembled between the two vertical support plates along the up-down direction. The magnet 9 is connected to the two discharge plates 12 respectively through two connecting rods.

[0086] When the indoor air purification device is in normal working state, the bottom ends of the two discharge plates 12 contact each other to block the top of the discharge cavity, the sealing plate 11 is in a drooping state, and the gas sucked by the fan 2 enters the exhaust cavity after being filtered by the filter plate and is discharged from the air outlet 102. When the indoor air purification device is in a cleaning state, the magnet 9 is attracted by the magnetic block on the filter plate swinging downward and moves upward, the bottom ends of the discharge plates 12 are separated from each other, the sealing plate 11 is pushed to a horizontal position to block the exhaust cavity, and the impurities blown off the filter plate can fall into the discharge cavity.

[0087] When the indoor air purification device provided by the present invention is working normally, part of the wind sucked in by the fan 2 enters the filter chamber 105, enters the exhaust chamber after being filtered by the filter plate and is discharged from the exhaust port, and the other part enters the energy storage chamber 104 to blow the blade wheel 15 to rotate and drive the torsion spring 16 to twist and store energy. When the filter plate is blocked, the wind entering the filter chamber 105 cannot pass through the upper filter plate 4. The upper filter plate 4 moves toward the lower bracket 5 under the action of wind pressure, so that the first locking structure is unlocked, and the torsion spring 16 releases energy to drive the annular shell 38 to rotate, and the annular shell 38 drives the moving ring 40 to rotate, and the moving ring 40 drives the first gear 37 to rotate, thereby driving the rotating shaft 17 to rotate, and the rotating shaft 17 drives the filter plate to flip downward. During the flipping process, the magnetic block attracts the magnet 9 to move upward to close the exhaust chamber and open the discharge chamber. In the process of the filter plate flipping from the horizontal state to the vertical state, the upper filter plate 4 is in an inclined state, and the wind sucked by the fan 2 passes through the upper surface of the inclined upper filter plate 4, blowing away the impurities stuck on the surface of the upper filter plate 4 that are easy to fall off, and the blown impurities slide into the discharge cavity through the discharge plate 12. Since the friction block 8 is provided on the partition plate 3, the friction block 8 slows down the speed of the filter plate rotating downward, and the filter plate stays in the inclined state for a longer time, so that the impurities are fully blown off.

[0088] After the filter plate passes through the friction block 8, it continues to flip. After passing the vertical position, the upper filter plate 4 moves back to the lower bracket 5 under its own gravity and wind pressure, so that the second slide plate 33 is pressed against the partition plate 3, until the filter plate continues to rotate to the inclined support groove 304, and the second slide plate 33 is inserted into the inclined support groove 304, so that the filter plate is locked at this position, and the wind sucked by the fan 2 blows to the lower surface of the blocked upper filter plate 4, and the impurities on the upper filter plate 4 are impacted in the reverse direction, so that the impurities fall off. When the filter plate is locked by the second locking structure, the guide rod 26 is pushed by the arc slide 24 to the position on the push surface 2401 farthest from the partition plate 3, and the sliding ring 25 drives the moving ring 40 to move to the second gear 21.

[0089] Since the filter plate is locked by the second locking structure at this time, the rotating shaft 17 cannot rotate, and the wind entering the energy storage chamber 104 continues to blow the blade wheel 15 to rotate, thereby driving the torsion spring 16 to twist and store energy. After the blockage of the upper filter plate 4 is relieved, the wind pressure on the upper filter plate 4 is reduced, and the upper filter plate 4 begins to move toward the lower bracket 5. The second locking structure is unlocked. At this time, the torsion spring 16 releases energy to drive the drive ring and the second gear 21 to rotate, and the second gear 21 drives the rotating shaft 17 to rotate in the opposite direction, and the rotating shaft 17 drives the filter plate to swing in the opposite direction. When the filter plate swings to a horizontal position, the first slide plate 34 is correspondingly inserted into the horizontal support groove 303 to achieve reset.

[0090] The present invention can automatically clean the filter plate when the filter plate is clogged, and there is no need to remove the filter plate for cleaning, which reduces the number of manual interventions, saves time and effort, and has higher cleaning efficiency.

[0091] In this embodiment, the reset mechanism includes a first gear 37, a second gear 21, a sliding ring 25, an arcuate slide 24 and a drive ring. In other embodiments, the reset mechanism includes a sliding seat slidably assembled on the casing along the left and right directions, a motor installed on the sliding seat and an electric telescopic rod for driving the sliding seat to slide left and right. The output shaft of the motor is coaxial with the rotating shaft 17. When the filter plate flips over the set angle, the electric telescopic rod drives the sliding seat to drive the motor to move toward the rotating shaft 17, so that the end face of the rotating shaft 17 is in contact with the end face of the motor output shaft, and then the motor is started to drive the filter plate to rotate in the opposite direction through friction transmission to reset the filter plate.

[0092] In this embodiment, two symmetrically arranged filter plates are provided on the shell 1. In other embodiments, only one filter plate is provided in the shell 1. The filter plate can block half of the side space between the two partition plates 3. At this time, when the filter plate is working normally, the baffle 6 is blocked above the area between the two partition plates 3 that is not blocked by the filter plate. When the filter plate is rotated to be locked by the second locking structure, the baffle 6 moves to above the area where the filter plate is located when it is working normally, without affecting the wind blowing to the bottom of the filter plate to clean the filter plate.

[0093] In this embodiment, an arc-shaped slide groove 301 is provided on the partition plate 3 , and the friction block 8 is slidably assembled in the arc-shaped slide groove 301 . In other embodiments, the friction block 8 is fixedly installed on the partition plate 3 .
