TECHNICAL FIELD

[0001] The present application relates to the technical field of air purification, in particular to an indoor formaldehyde efficient purifier. BACKGROUND

[0002] ‌The formaldehyde purifier is a kind of air purification equipment specially designed to remove harmful substances such as formaldehyde in indoor air, and its main working principle is to adsorb, decompose or convert formaldehyde molecules in the air into harmless substances through multiple filter screens and specific technical means, so as to improve indoor air quality.

[0003] The formaldehyde purifier mainly consists of a shell, a filter core and a fan, the shell is provided with an air inlet and an air outlet, the filter core is installed in the shell, and the fan is fixedly installed above the filter core, the fan is opposite to the air outlet, and the formaldehyde purifier is started to rotate when working, the fan draws air to make the external air enter the formaldehyde purifier, the entering air is filtered by the filter core to remove dust, formaldehyde and other harmful substances in it, and finally discharged from the air outlet under the action of the fan, thereby playing a role of air purification.

[0004] At that time, in the process of long-time working of the formaldehyde purifier, the dust and formaldehyde adsorbed on the filter core at the air inlet of the formaldehyde purifier gradually increase, thereby reducing the purification efficiency, and at the same time, when the fan works, the airflow will blow off the dust and formaldehyde accumulated on the filter core, thereby being discharged from the air outlet, resulting in the generation of secondary pollution.

[0005] In view of this, we propose an indoor formaldehyde efficient purifier. SUMMARY

[0006] The present application relates to the technical field of air purification, in particular to an indoor formaldehyde efficient purifier.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical scheme: The utility model provides an indoor formaldehyde high -efficient purifier, including formaldehyde purifier shell, filter core, fan, rotation subassembly, cleaning rod, vibration subassembly and vibration plate, formaldehyde purifier shell divides into outer shell and inner shell, the lower end of outer shell is equipped with air inlet, the upper end of outer shell is equipped with air outlet, and the upper of inner shell is equipped with through -hole, the outer shell and inner shell constitute the purification cavity, collection cavity and changeover cavity that communicate with each other, and the collection hole is equipped between the purification cavity and collection cavity, be equipped with pi -shaped partition plate in the purification cavity and carry out space division, install filter core in the purification cavity, and pi -shaped partition plate is divided into upper end and lower end by horizontal end, and the lower end is divided into two spaces by vertical end, and the purification cavity is divided into three spaces that are separated from each other in total, and three spaces are all fixedly installed with filter core, are used for purifying air, the fan is fixedly installed in the top of purification cavity, and the fan corresponds with the air outlet, and when formaldehyde purifier is working, first, start the fan, and the fan rotates and generates suction, and the outside air is sucked into formaldehyde purifier from the air inlet, and the outside air contacts filter core, and filter core absorbs dust and formaldehyde in the air, and then realizes the purification of air, and the air that is purified enters changeover cavity through through -hole, and air continues to move upwards along changeover cavity under the action of fan, then enters the upper end of purification cavity through the through -hole in the upper end of inner shell and contacts the filter core in it, carries out secondary purification, guarantees the purification efficiency of air, and finally is discharged from the air outlet under the action of fan, and completes one side purification work, The fan is below the rotation subassembly, which is located in the changeover cavity. The rotation subassembly is below the cleaning rod, which is located in the collection cavity. When the fan rotates, the fan drives the cleaning rod to move intermittently through the rotation subassembly. When the fan rotates to draw air, it drives the rotation subassembly to rotate synchronously. The rotation drives the cleaning rod to move intermittently, achieving alternating cleaning of the two spaces in the lower end of the purification cavity. This avoids the dust cleaned by the cleaning rod from being carried away by the air and discharged from the air outlet, ensuring the purification quality. The cleaning rod is above the vibration subassembly, which is symmetrically installed in the purification cavity. The vibration subassembly has vibration plates on both sides, which are attached to the outer shell and the inner shell. When the cleaning rod moves, it drives the vibration plates to move centrally through the vibration subassembly. The vibration plates cooperate with the cleaning rod to clean the filter core. At the same time, the dust cleaned is discharged into the collection cavity, making it convenient for users to clean.

[0008] Preferably, the through-hole at the lower end of the inner shell is misaligned with the air inlet. The diameter of the through-hole is smaller than that of the air inlet. The misaligned arrangement of the through-hole and the air inlet increases the movement trajectory of the air in the filter core, thereby improving the purification quality of the filter core for the air. At the same time, the smaller diameter of the through-hole than that of the air inlet makes the air inlet speed of the purification cavity smaller than the air outlet speed, thereby increasing the residence time of the air in the purification cavity, allowing the filter core to fully contact the air and improving the purification quality of the air.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Formaldehyde purifiers mainly consist of a shell, a filter element, and a fan. The shell has an air inlet and an air outlet. The filter element is installed inside the shell, and the fan is fixedly installed above the filter element, facing the air outlet. When the formaldehyde purifier is working, the fan starts to rotate, drawing in air and allowing outside air to enter the purifier. The incoming air is filtered by the filter element to remove dust, formaldehyde, and other harmful substances. Finally, the air is discharged from the air outlet under the action of the fan, thus achieving the function of air purification.

[0024] At that time, during the long-term operation of the formaldehyde purifier, the dust and formaldehyde adsorbed on the filter at the air inlet of the formaldehyde purifier gradually increased, which led to a decrease in purification efficiency. At the same time, when the fan was working, the airflow would blow off the accumulated dust and formaldehyde from the filter and discharge it from the air outlet, resulting in secondary pollution.

[0025] The present invention provides a technical solution: like Figures 1 to 12 As shown, an indoor formaldehyde high-efficiency purifier includes a formaldehyde purifier housing 1, a filter element 2, a fan 3, a rotating assembly 4, a cleaning rod 5, a vibration assembly 6, and a vibration plate 7. The formaldehyde purifier housing 1 is divided into an outer shell 11 and an inner shell 12. The lower end of the outer shell 11 has an air inlet 111, and the upper end of the outer shell 11 has an air outlet 112. The inner shell 12 has a through hole 121. The outer shell 11 and the inner shell 12 form a purification chamber 13, a collection chamber 14, and a reversing chamber 15 that are interconnected. A collection hole 141 is provided between the purification chamber 13 and the collection chamber 14. A π-shaped partition plate 131 is provided in the purification chamber 13 for spatial division. The chamber is equipped with a filter element 2; the fan 3 is fixedly installed at the top of the purification chamber 13, and the fan 3 corresponds to the air outlet; a rotating assembly 4 is provided below the fan 3, the rotating assembly 4 is located in the reversing chamber 15, a cleaning rod 5 is provided below the rotating assembly 4, and the cleaning rod 5 is located in the collection chamber 14. When the fan 3 rotates, the fan 3 drives the cleaning rod 5 to move intermittently through the rotating assembly 4. A vibration assembly 6 is provided above the cleaning rod 5, the vibration assembly 6 is symmetrically installed in the purification chamber 13, and vibration plates 7 are provided on both sides of the vibration assembly 6. The vibration plates 7 are in contact with the outer shell 11 and the inner shell 12; when the cleaning rod 5 moves, the cleaning rod 5 drives the vibration plates 7 to move in the center through the vibration assembly 6. Specifically, the formaldehyde purifier housing 1 is divided into an outer shell 11 and an inner shell 12. The lower end of the outer shell 11 has an air inlet 111, and the upper end of the outer shell 11 has an air outlet 112. The inner shell 12 has a through hole 121. The outer shell 11 and the inner shell 12 form a purification chamber 13, a collection chamber 14, and a reversing chamber 15 that are interconnected. Air enters the purification chamber 13 through the air inlet 111 of the outer shell 11, and then enters the reversing chamber through the through hole 121 at the lower end of the inner shell 12. The dust enters the purification chamber 13 through the through hole 121 at the upper end of the inner shell 12 and exits through the air outlet 112 at the upper end of the outer shell 11. A collection hole 141 is provided between the purification chamber 13 and the collection chamber 14 to discharge the dust in the purification chamber 13 into the collection chamber 14. The collection chamber 14 is provided with a dust removal port to remove the collected dust from the collection chamber. A π-shaped partition plate 131 is provided in the purification chamber 13 for spatial division. A filter element 2 is installed in the purification chamber 13. The U-shaped partition 131 divides the purification chamber 13 into an upper and lower section by the horizontal end and into two spaces by the vertical end, thus dividing the purification chamber 13 into three separate spaces. Filter elements 2 are fixedly installed in each of the three spaces for air purification. The fan 3 is fixedly installed at the top of the purification chamber 13, corresponding to the air outlet. When the formaldehyde purifier is working, the fan 3 is started first. The fan 3 rotates and generates suction, drawing outside air into the formaldehyde purifier from the air inlet 111. The outside air comes into contact with the filter element 2, which adsorbs dust in the air, thereby purifying the air. The purified air enters the reversing chamber 15 through the through hole 121. Under the action of the fan 3, the air continues to move upward along the reversing chamber 15, and then enters the upper part of the purification chamber 13 through the through hole 121 at the upper end of the inner shell to come into contact with the filter element 2 inside for secondary purification, ensuring the air purification efficiency. Finally, under the action of the fan 3, the air is discharged from the air outlet 112, completing the purification work on one side. A rotating assembly 4 is located below the fan 3, within the reversing chamber 15. A cleaning rod 5 is located below the rotating assembly 4, within the collection chamber 14. When the fan 3 rotates, it drives the cleaning rod 5 to move intermittently via the rotating assembly 4. When the fan 3 rotates to extract air, it drives the rotating assembly 4 to rotate synchronously. This rotational motion drives the cleaning rod 5 to move intermittently, achieving alternating cleaning of the two spaces at the lower end of the purification chamber 13. This prevents the dust removed by the cleaning rod 5 from being carried away by the air and discharged through the air outlet 112, ensuring purification quality. A vibration assembly 6 is located above the cleaning rod 5, symmetrically installed within the purification chamber 13. Vibration plates 7 are located on both sides of the vibration assembly 6, fitting snugly against the outer shell 11 and inner shell 12. When the cleaning rod 5 moves, it drives the vibration plates 7 to move in the center via the vibration assembly 6. The vibration plates 7, in conjunction with the cleaning rod 5, clean the filter element 2. Simultaneously, the cleaned dust is discharged into the collection chamber 14 for easy cleaning by the user.

[0026] In this embodiment, the lower end through hole 121 of the inner shell 12 is installed in a misaligned manner with the air inlet 111, and the diameter of the through hole 121 is smaller than the diameter of the air inlet 111. Specifically, the staggered arrangement of the through hole 121 and the air inlet 111 increases the movement trajectory of air within the filter element 2, thereby enhancing the air purification quality of the filter element 2 and preventing incomplete purification caused by rapid airflow through the filter element 2. At the same time, the diameter of the through hole 121 is smaller than the diameter of the air inlet 111, making the air intake velocity of the purification chamber 13 lower than the air exhaust velocity, thereby increasing the residence time of air within the purification chamber 13, thus allowing the filter element 2 to fully contact the air and improving the air purification quality.

[0027] In this embodiment, the rotating assembly 4 includes a drive shaft 41, a drive wheel 42, an internal gear ring 43, a baffle plate 44, a transmission wheel 45, and a synchronous pulley set 46. The drive shaft 41 is fixedly installed with the fan 3 and is located inside the reversing cavity 15. The drive wheel 42 is fixedly installed at the lower end of the drive shaft 41. The drive wheel 42 is a half-tooth gear. An internal gear ring 43 is provided on the outer circumference of the drive shaft 41. The internal gear ring 43 is rotatably installed with the inner housing 12. A baffle plate 44 is fixedly installed on the internal gear ring 43. A transmission wheel 45 is provided between the drive wheel 42 and the internal gear ring 43. The transmission wheel 45 meshes with the drive wheel 42 and the internal gear ring 43. The synchronous pulley set 46 is symmetrically installed with the transmission wheel 45 and is connected to the cleaning rod 5. A cleaning protrusion 51 is provided on the cleaning rod 5. The upper end of the cleaning protrusion 51 is located inside the purification cavity 13 and contacts the filter element 2. Specifically, the drive shaft 41 is fixedly installed with the fan 3, and the drive shaft 41 rotates synchronously with the fan 3. The drive shaft 41 is located inside the reversing cavity 15, and a drive wheel 42 is fixedly installed at the lower end of the drive shaft 41. The drive wheel 42 is a semi-tooth gear, and an internal gear ring 43 is provided on the outer circumference of the drive shaft 41. The internal gear ring 43 is rotatably installed with the inner housing 12, and the internal gear ring 43 and the inner housing 12 can be rotatably connected through a limiting block and a limiting groove. A baffle plate 44 is fixedly installed on the internal gear ring 43. The drive wheel 42 and the inner housing 12 are rotatably installed. A transmission wheel 45 is provided between the gear rings 43. The transmission wheel 45 is rotatably mounted to the inner housing 12 via a rotating shaft. The transmission wheel 45 meshes with the drive wheel 42 and the inner gear ring 43. When the fan 3 rotates, it drives the drive shaft 41 to rotate synchronously, which in turn drives the drive wheel 42 to rotate synchronously. The drive wheel 42 meshes with the transmission wheel 45, which in turn drives the transmission wheel 45 to rotate. The transmission wheel 45 drives the inner gear ring 43 to rotate synchronously, and the inner gear ring 43 drives the baffle plate 44 to rotate synchronously, thus affecting one of the two spaces at the lower end. The baffle plate 44 is partially obstructed. Because the drive wheel 42 is a semi-gear, it only engages with the transmission wheel 45 halfway through one rotation, causing the transmission wheel 45 to rotate. The transmission wheel 45 then drives the internal gear ring 43 to rotate halfway before remaining stationary, thus achieving intermittent movement of the baffle plate 44. Simultaneously, the drive wheel 42 continues to rotate. The synchronous pulley set 46 is symmetrically installed with the transmission wheel 45 and is connected to the cleaning rod 5. The cleaning rod 5 is equipped with a cleaning protrusion 51, the upper end of which is located within the purification chamber. Within 13, and in contact with filter element 2; when drive wheel 42 and transmission wheel 45 are not meshed, drive synchronous wheel set 46 to work, synchronous wheel set 46 drives cleaning plate to rotate, cleaning plate rotation causes cleaning protrusion 51 to contact filter element 2 in the space blocked by baffle plate 44 to generate friction, thereby driving filter element 2 to vibrate, shaking off the dust adhering to filter element 2. At this time, the space is blocked by baffle plate 44, there is no gas flow, thus the dust will not be disturbed by airflow, affecting air purification and avoiding secondary pollution.

[0028] In this embodiment, a helical blade 411 is provided on the drive shaft 41, and the helical blade 411 corresponds to the through hole 121; Specifically, when the drive shaft 41 rotates, it drives the spiral blades 411 on it to rotate synchronously. The spiral blades 411 convey air and at the same time, they uniformly mix the air in the reversing cavity 15 to ensure uniformity during secondary purification, thereby ensuring purification efficiency. Meanwhile, the spiral blades 411 correspond to the through hole 121, and the edge of the spiral blades 411 pressurizes the air, thereby promoting the air to enter the upper end of the purification cavity 13 from the through hole 121 to complete secondary purification, thus improving purification efficiency.

[0029] In this embodiment, the baffle plate 44 is provided with a sealing protrusion 441 that mates with the through hole 121; Specifically, when the baffle plate 44 is fixed, the sealing protrusion 441 fixes the through hole 121 to ensure the sealing of the reversing cavity 15, thereby preventing the dust from the vibration from entering the reversing cavity 15 and then being discharged from the outlet 112. When the baffle plate 44 rotates, the sealing protrusion 441 rotates synchronously with the baffle plate 44 and coincides with the through hole 121. At this time, the sealing protrusion 441 achieves reverse pressurization of the air in the purification cavity 13 through the protrusion, thereby increasing the residence time of the air in the purification cavity 13, so that the filter element 2 can fully contact the air and ensure the purification effect of the air. Preferably, the sealing protrusion 441 is made of rubber material. The rubber material allows the sealing protrusion 441 to deform, thereby reducing the friction between the sealing protrusion 441 and the inner housing 12 during the rotation of the baffle plate 44 and improving the smoothness of rotation.

[0030] In this embodiment, the synchronous pulley set 46 includes a driving pulley 461, a driven pulley 462, a drive shaft 463, and an intermittent pulley 464. The driving pulley 461 is located in the reversing cavity 15 and is symmetrically installed with the drive pulley 45. The driving pulley 461 meshes with the drive pulley 42, and the driven pulley 462 is provided below the driving pulley 461. The driven pulley 462 is located in the collecting cavity 14, and the driven pulley 462 is connected to the driving pulley 461 through the drive shaft 463. The drive shaft 463 is rotatably connected to the inner housing 12 through a bearing. An intermittent pulley 464 is provided on one side of the driven pulley 462. The intermittent pulley 464 is coaxially installed with the drive pulley 42, and the intermittent pulley 464 is fixedly installed with the cleaning rod 5. Specifically, the drive wheel 461 is located in the reversing cavity 15 and is symmetrically installed with the transmission wheel 45. The drive wheel 461 meshes with the drive wheel 42. When the drive wheel 42 separates from the transmission wheel 45, the drive wheel 42 meshes with the drive wheel 461, thereby driving the drive wheel 461 to rotate. Since the diameter of the drive wheel 461 is smaller than that of the transmission wheel 45, the drive wheel 461 does not mesh with the internal gear ring 43, thus keeping the internal gear ring 43 fixed and the baffle plate 44 stationary. A driven wheel 462 is provided below the drive wheel 461. The driven wheel 462 is located in the collecting cavity 14 and is connected to the drive wheel 461 by a transmission shaft 463. The transmission shaft 463 is rotatably connected to the inner housing 12 through a bearing. When the drive wheel 461 rotates, it drives the driven wheel through the transmission shaft 463. 462 rotates synchronously; the drive shaft 463 is rotatably connected to the inner housing 12 via bearings; an intermittent wheel 464 is provided on one side of the driven wheel 462; the intermittent wheel 464 is coaxially mounted with the drive wheel 42, and the intermittent wheel 464 is fixedly mounted with the cleaning rod 5. When the driven wheel 462 rotates, it meshes with the intermittent wheel 464, driving the intermittent wheel 464 to rotate. The intermittent wheel 464 drives the cleaning rod 5 to move synchronously. The cleaning rod 5 moves from one end of the baffle plate 44 to the other end, thereby cleaning the filter element 2 in the space where the baffle plate 44 is located, so that dust and formaldehyde are removed from the filter element 2. When the cleaning rod 5 moves to the other end of the baffle plate 44, the drive wheel 42 no longer meshes with the drive wheel 461, and the cleaning rod 5 stops moving and no longer cleans the filter element 2, preventing the air from bringing dust into the reversing chamber 15.

[0031] In this embodiment, the cleaning bump 51 is a hemispherical structure 511; Specifically, the hemispherical structure 511 generates vibration through friction on the filter element 2 while reducing the contact stress of the cleaning protrusion 51 on the filter element 2, thus avoiding damage to the filter element 2 due to high contact stress and ensuring the service life of the filter element 2.

[0032] In this embodiment, the vibration assembly 6 includes a baffle 61, a rotating wheel 62, a torsion spring 63, a pull plate 64, and a collecting brush 65. There are two baffles 61, located on the movement trajectory of the cleaning plate 5 and rotatably mounted within the purification chamber 13. The baffles 61 are connected to the inner wall of the purification chamber 13 via the torsion spring 63, and the baffles 61 are fixedly mounted to the rotating wheel 62. The rotating wheel 62 is located within the pull plate 64. The pull plate 64 has a strip-shaped groove 641, within which are teeth that mate with the rotating wheel 62. A vibration plate 7 is fixedly mounted on the pull plate 64. A collecting brush 65 is located below the vibration plate 7, and the collecting brush 65 is located on one side of the collecting hole 141. Specifically, there are two baffles 61, which are rotatably installed inside the purification chamber 13. During the rotation of the cleaning rod 5, the cleaning protrusion 51 on the cleaning rod 5 contacts the baffles 61, thereby pushing the baffles 61 to rotate. The baffles 61 are connected to the inner wall of the purification chamber 13 by a torsion spring 63, which is used to realize the reset movement of the baffles 61. When the cleaning rod 5 is no longer in contact with the baffles 61, the torsion spring 63 drives the baffles 61 to reverse and reset. The baffles 61 are fixedly installed with the rotating wheel 62. The rotating wheel 62 is located inside the pull plate 64. The pull rod and the inner housing 12 are slidably connected by a limiting block and a limiting groove, thereby limiting the movement trajectory of the pull rod. The pull plate 64 has a strip groove 641. The groove 641 is provided with gear teeth that cooperate with the rotating wheel 62; a vibrating plate 7 is fixedly installed on the pull plate 64. When the baffle 61 rotates, it drives the rotating wheel 62, which is fixedly connected to it, to rotate synchronously. The rotating wheel 62 meshes with the gear teeth in the strip groove 641, thereby driving the pull rod to move along the center of the filter element 2. The pull rod drives the vibrating plate 7 to move synchronously. The centering movement of the vibrating plate 7 squeezes the filter element 2, thereby causing the filter element 2 to vibrate. This, together with the cleaning rod 5, cleans the filter element 2. A collecting brush 65 is provided below the vibrating plate 7. The collecting brush 65 is located on one side of the collecting hole 141. During the movement of the vibrating plate 7, it drives the collecting brush 65 to move synchronously. The collecting brush 65 sweeps the dust from the collecting hole 141 into the collecting chamber 14 for storage.

[0033] In this embodiment, the vibrating plate 7 is provided with a linear array of pressure-boosting protrusions 71; Specifically, the pressure-boosting protrusion 71 is used to enhance the collision effect between the vibrating plate 7 and the filter element 2, thereby enhancing the vibration effect of the filter element 2, promoting the removal of dust from the filter element 2, and improving the cleaning efficiency of the filter element 2.

[0034] In this embodiment, the baffle 61 is provided with an arc surface 611 that cooperates with the cleaning protrusion 51; Specifically, the curved surface 611 increases the contact area between the baffle 61 and the cleaning protrusion 51 on the cleaning rod 5, thereby enhancing the interaction force between the cleaning protrusion 51 and the baffle 61, thus improving the smoothness of the cleaning protrusion 51 in pushing the baffle 61 to rotate, and thus improving the cleaning efficiency.

[0035] In use, the indoor formaldehyde purifier of this invention is activated by the user. The fan 3 rotates to draw in air, allowing it to come into contact with the filter element 2 for purification. Simultaneously, the fan 3 drives the drive shaft 41 to rotate synchronously, which in turn drives the drive wheel 42 to rotate synchronously. The drive wheel 42 meshes with the transmission wheel 45, which in turn rotates and meshes with the internal gear ring 43, driving the internal gear ring 43 to rotate synchronously. The internal gear ring 43 drives the baffle plate 44 to rotate synchronously, sealing one of the two spaces at the lower end of the purification chamber 13, preventing air from entering that space. After the drive wheel 42 rotates half a turn, it separates from the transmission wheel 45, which then stops rotating. The internal gear ring 43 then keeps the baffle plate 44 fixed. The drive wheel 42 continues to rotate and meshes with the drive wheel 461, driving... The driving wheel 461 rotates, which drives the driven wheel 462 to rotate synchronously via the transmission shaft 463. The driven wheel 462 meshes with the intermittent wheel 464, which drives the cleaning rod 5 to rotate and clean the filter element 2 in the sealed space. During the rotation of the cleaning plate, the cleaning plate contacts the baffle 61, which in turn pushes the baffle 61 to rotate. The baffle 61 drives the rotating wheel 62 to rotate synchronously. The rotating wheel 62 drives the pull rod to slide, and the pull rod drives the vibrating plate 7 to move in the center to clean the filter element 2. At the same time, the vibrating plate 7 drives the collecting brush 65 to send dust into the collecting chamber 14 through the collecting hole 141 for collection. When the cleaning plate separates from the baffle 61, the torsion spring 63 drives the baffle 61 to reverse, the baffle 61 drives the rotating wheel 62 to reverse, the rotating wheel 62 drives the pull rod to reset, and the pull rod drives the vibrating plate 7 to reset. However, after the drive wheel 42 rotates once, the drive wheel 42 engages with the transmission wheel 45 again, and the above process is repeated to clean the filter element 2 in another space.
