[0002] An air purification device for a building environment usually consists of a purification frame, a water tank, a ventilator, an atomization pump machine and other parts.

[0003] The patent with the patent announcement number CN216281912U relates to an air purification device for building environment governance, including a purification box. A movable door one is hinged in a through hole opened on the right side of the purification box, and a handle one is fixedly connected to the movable door one. An activated carbon block is placed in the purification box, and a dust removal device is arranged above the activated carbon block in the purification box. The dust removal device includes a partition one, an air pump, a flange, a U-shaped pipe, a dust-proof net one, a conduit and an air suction port. The partition one is fixedly connected to the inner wall of the purification box, and the air pump is fixedly installed on the upper surface of the partition one. By setting the dust removal device, air and dust are sucked in together, and then the dust is separated, and the dust settles at the bottom of the U-shaped pipe for collection and treatment, solving the problem that traditional dust-proof measures can only reduce dust, and the dust will continue to rise into the air after the water evaporates.

[0004] In the above patent, by setting the dust removal device, air and dust are sucked in together, and then the dust is separated, and the dust settles at the bottom of the U-shaped pipe for collection and treatment, solving the problem that traditional dust-proof measures can only reduce dust, and the dust will continue to rise into the air after the water evaporates. However, it is difficult to improve the air circulation efficiency inside the purification frame. If the air circulation inside the purification frame is not smooth, the filtering and purification processes cannot be fully carried out, and pollutants in the air cannot be effectively removed, ultimately affecting the overall purification effect.

[0015] The present invention provides an air purification device for a building environment. It has the following beneficial effects: (1) For the air purification device for a building environment, the scraping rod reciprocates to contact the separation plate and scrape the left side of the separation plate. By regularly scraping with the scraping rod, the accumulation of impurities is reduced, which helps to reduce the resistance of air flow, makes the air pass through the purification frame more smoothly, and thus improves the overall air purification effect. The activated carbon plate rotates to clean the inner wall of the air inlet pipe and adsorb the odor gas in the air. Through the rotation cleaning of the activated carbon plate, the air inlet pipe can be kept clean, and at the same time, the rotation of the activated carbon plate can ensure that the area of its surface in contact with the air increases, thereby improving the adsorption efficiency of the odor.

[0016] (2) For the air purification device for a building environment, the quantitative oil mist trapping liquid entering the internal of the liquid storage frame enters the internal of the liquid injection frame through the liquid inlet hole. By quantitatively adding the oil mist trapping liquid, it can ensure that the oil mist generated during construction is adsorbed and converted in time and effectively, avoiding the oil mist remaining in the purification frame, thereby improving the efficiency of the entire purification process.

[0017] (3) For the air purification device for building environment, the T-shaped rod can only move slowly upward, causing the liquid injection plate to move slowly upward. When the ventilator starts, if the airflow change inside the purification frame is too drastic, it will cause the trapping liquid to overflow or leak. By slowly raising the liquid injection plate, sudden air pressure changes can be effectively avoided, thereby maintaining the seal of the oil mist trapping liquid and reducing the leakage risk.

[0018] (4) For the air purification device for building environment, the free end of the elastic telescopic rod moves upward to contact and support the connecting pipe. The elastic telescopic rod can provide effective support for the connecting pipe during the air purification process, avoiding pipe deformation and impact caused by construction collisions, and thus ensuring the continuity of air purification.

[0019] (5) For the air purification device for building environment, when the button moves upward, it is blocked by the fixed end of the elastic telescopic rod and cannot be pressed. If the external force causes the atomization pump to interrupt its operation, the water mist will stop, thereby reducing the air humidification and purification effects. By ensuring the continuous operation of the atomization pump, the stable release of water mist in the air can be guaranteed, and thus the air quality can be continuously improved.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-7 , an embodiment of the present invention is: An air purification device for a building environment, including a purification frame 1, and further including a separation component. The left side of the purification frame 1 is fixedly penetrated with an air inlet pipe 2, the right side of the purification frame 1 is fixedly penetrated with an air supply pipe 3, a ventilator 4 is arranged inside the air supply pipe 3, a water tank 5 is fixedly installed on the top of the purification frame 1, an atomization pump 6 is fixedly installed on the top of the purification frame 1, a connecting pipe 7 is arranged between the atomization pump 6 and the water tank 5, a placing plate 8 is fixedly installed on the inner wall of the purification frame 1, a sealing frame 9 is fixedly installed on the right side of the placing plate 8, a servo motor 10 is fixedly installed inside the sealing frame 9, the output end of the servo motor 10 is fixedly installed with a rotating rod 11, a separation plate 12 is fixedly installed on the inner wall of the air inlet pipe 2, a fixed plate 13 is fixedly installed on the circumferential surface of the rotating rod 11, a scraping rod 14 is slidably installed on the circumferential surface of the rotating rod 11, and an arc-shaped block 15 is fixedly installed on the left side of the separation plate 12. Regular scraping by the scraping rod 14 reduces the accumulation of impurities, helps reduce the resistance of air flow, enables air to pass through the purification frame 1 more smoothly, and thus improves the overall air purification effect.

[0024] A first spring is provided between the fixed plate 13 and the scraping rod 14. The first spring can drive the scraping rod 14 to reset. The scraping rod 14 contacts the left side of the separation plate 12. An activated carbon plate 16 is fixedly installed on the circumferential surface of the rotating rod 11. The rotation of the activated carbon plate 16 cleans the inner wall of the air inlet pipe 2 and adsorbs the odor gas in the air. Through the rotation cleaning of the activated carbon plate 16, the air inlet pipe 2 can be kept clean. At the same time, the rotation of the activated carbon plate 16 can ensure an increase in the area of its surface in contact with the air, thereby improving the adsorption efficiency of the odor.

[0025] A liquid storage frame 171 is fixedly installed on the circumferential surface of the air inlet pipe 2. The rotating rod 11 penetrates the left and right walls of the placing plate 8, and the rotating rod 11 penetrates the left and right walls of the separation plate 12. The ventilator 4 drives the humid air to be ejected from the air supply pipe 3, so that the mist beads adsorb the dust in the air and settle with the dust.

[0026] When this embodiment works: The ventilator 4 operates to suck air into the purification frame 1 through the air inlet pipe 2. At the same time, the servo motor 10 operates to drive the rotating rod 11 to rotate. The rotation of the rotating rod 11 drives the scraping rod 14 to rotate. The scraping rod 14 rotates and contacts the arc-shaped block 15 and squeezes the arc-shaped block 15. The scraping rod 14 moves away from the servo motor 10 under the reaction force of the arc-shaped block 15. The scraping rod 14 moves away from the servo motor 10 and squeezes the first spring. The first spring deforms and stores energy under the extrusion of the scraping rod 14. When the servo motor 10 continues to operate to drive the rotating rod 11 to continue rotating, the rotating rod 11 continues to rotate to drive the scraping rod 14 to continue rotating. The scraping rod 14 continues to rotate and disengages from the contact with the arc-shaped block 15. After the scraping rod 14 disengages from the contact with the arc-shaped block 15, the scraping rod 14 moves back to the direction close to the servo motor 10 under the elastic force of the first spring to reset. The scraping rod 14 reciprocates to contact the separation plate 12 and scrape the left side of the separation plate 12. At the same time, the rotating rod 11 rotates to drive the activated carbon plate 16 to rotate. The rotation of the activated carbon plate 16 cleans the inner wall of the air inlet pipe 2 and adsorbs the odor gas in the air. At the same time, the atomizing pump 6 operates. The operation of the atomizing pump 6 can humidify the air filtered by the separation plate 12. After the air is mixed with the water droplets, the ventilator 4 drives the humid air to be ejected from the air supply pipe 3, so that the mist beads adsorb the dust in the air and settle with the dust.

[0027] Please refer to Figures 1-8, on the basis of the above embodiments, in another embodiment of the present invention, a liquid injection assembly for improving the separation effect of the separation plate 12 is provided on the circumferential surface of the air inlet pipe 2, and a support assembly is provided on the top of the purification frame 1. The liquid injection assembly includes a liquid injection frame 172, a T-shaped rod 173, a liquid injection plate 174, an inclined plane rod 175, a liquid injection hole 176 and a liquid inlet hole 1711. The liquid injection frame 172 is fixedly installed at the bottom of the inner wall of the liquid storage frame 171. The liquid injection plate 174 is slidably installed on the inner wall of the liquid injection frame 172. The T-shaped rod 173 is fixedly installed on the top of the liquid injection plate 174. The inclined plane rod 175 is fixedly installed at the bottom of the liquid injection plate 174. The liquid injection hole 176 is opened at the bottom of the liquid storage frame 171. The liquid inlet hole 1711 is opened on the circumferential surface of the liquid injection frame 172. An oil mist trapping liquid is provided inside the liquid storage frame 171. By quantitatively adding the oil mist trapping liquid, it can be ensured that the oil mist generated during construction is adsorbed and converted in a timely and effective manner, avoiding the oil mist remaining inside the purification frame 1, thereby improving the efficiency of the entire purification process.

[0028] A protective frame 177 is fixedly installed at the bottom of the inner wall of the liquid storage frame 171. A protective hole 178 is opened at the top of the protective frame 177. A protective rod 179 is fixedly installed at the top of the T-shaped rod 173. A protective block 1710 is fixedly installed on the right side of the protective rod 179. The upward movement of the T-shaped rod 173 drives the upward movement of the protective rod 179.

[0029] A second spring is provided between the T-shaped rod 173 and the liquid injection frame 172. The second spring can drive the T-shaped rod 173 to reset. The liquid injection plate 174 is in contact with the liquid inlet hole 1711. The protective block 1710 is elastic. The T-shaped rod 173 can only move upward slowly, so that the liquid injection plate 174 can only move upward slowly. By allowing the liquid injection plate 174 to rise slowly, sudden air pressure changes can be effectively avoided, thereby maintaining the seal of the oil mist trapping liquid and reducing the risk of leakage.

[0030] The support assembly includes a detection tube 181, a detection plate 182, a moving plate 183, an elastic telescopic rod 184, a moving hole 185, a load-bearing hole 186 and a button 187. The detection tube 181 is fixedly penetrated through the top of the purification frame 1. The detection plate 182 is slidably installed on the inner wall of the detection tube 181. The moving plate 183 is slidably installed on the inner wall of the detection tube 181. The elastic telescopic rod 184 is fixedly installed at the top of the purification frame 1. The moving hole 185 is opened on the circumferential surface of the fixed end of the elastic telescopic rod 184. The load-bearing hole 186 is opened on the circumferential surface of the free end of the elastic telescopic rod 184. The button 187 is fixedly installed on the inner wall of the load-bearing hole 186. The elastic telescopic rod 184 can provide effective support for the connecting pipe 7 during the air purification process, avoiding pipeline deformation and impact caused by construction collision, and thus ensuring the continuity of air purification.

[0031] An elastic telescopic block 188 is fixedly installed on the left side of the atomizing pump 6. The button 187 is electrically connected to the atomizing pump 6. The atomizing pump 6 can be started or stopped through the button 187. There is liquid inside the detection tube 181. The free end of the elastic telescopic block 188 contacts the free end of the elastic telescopic rod 184. By ensuring the continuous operation of the atomizing pump 6, the stable release of water mist in the air can be guaranteed, thereby continuously improving the air quality.

[0032] A first rubber ring is arranged between the detection tube 181 and the detection plate 182. The sealing performance of the detection tube 181 can be improved through the first rubber ring. A second rubber ring is arranged between the detection tube 181 and the moving plate 183. The sealing performance of the detection tube 181 can be improved through the second rubber ring. A third spring is arranged between the detection tube 181 and the moving plate 183. The moving plate 183 can be driven to reset through the third spring.

[0033] When this embodiment works: The rotating rod 11 rotates to drive the scraping rod 14 to rotate. The scraping rod 14 rotates and contacts the inclined surface of the inclined surface rod 175 and squeezes the inclined surface rod 175. The inclined surface rod 175 moves upward under the extrusion of the scraping rod 14. The upward movement of the inclined surface rod 175 drives the liquid injection plate 174 to move upward. The upward movement of the liquid injection plate 174 contacts the liquid inlet hole 1711 and releases the seal of the bottom of the liquid injection frame 172. After the seal of the bottom of the liquid injection frame 172 is released, the oil mist trapping liquid inside the liquid storage frame 171 enters the liquid injection frame 172 through the liquid inlet hole 1711. The oil mist trapping liquid entering the liquid injection frame 172 drips onto the left side of the separation plate 12 through the liquid injection hole 176. And the upward movement of the liquid injection plate 174 drives the T-shaped rod 173 to move upward. The T-shaped rod 173 moves upward to pull the second spring. The second spring deforms and stores energy under the pull of the T-shaped rod 173. At the same time, the upward movement of the T-shaped rod 173 drives the protection rod 179 to move upward. The upward movement of the protection rod 179 drives the protection block 1710 to move upward. The protection block 1710 moves upward and contacts the protection hole 178 and squeezes the protection hole 178. The protection block 1710 generates a slow deformation under the reaction force of the extrusion of the protection hole 178. The slow deformation of the protection block 1710 enables the protection rod 179 and the T-shaped rod 173 to only move upward slowly. The slow upward movement of the T-shaped rod 173 enables the liquid injection plate 174 to only move upward slowly.

[0034] The protective rod 179 moves upward to contact the detection plate 182 and extrude the detection plate 182. The detection plate 182 moves upward under the extrusion of the protective rod 179. The detection plate 182 moves upward to extrude the liquid inside the detection tube 181. The liquid inside the detection tube 181 moves to the right under the extrusion of the detection plate 182. The liquid inside the detection tube 181 moves to the right to extrude the moving plate 183. The moving plate 183 moves to the right under the extrusion of the liquid inside the detection tube 181. The moving plate 183 moves to the right to contact the inclined surface of the free end of the elastic telescopic rod 184 and extrude the free end of the elastic telescopic rod 184. The free end of the elastic telescopic rod 184 moves upward under the extrusion of the moving plate 183. The free end of the elastic telescopic rod 184 moves upward to contact the connecting pipe 7 and support the connecting pipe 7. At the same time, the free end of the elastic telescopic rod 184 moves upward to drive the button 187 to move upward. The button 187 cannot be pressed when it moves upward due to the occlusion of the fixed end of the elastic telescopic rod 184. And when the free end of the elastic telescopic rod 184 moves upward, it will be separated from the contact with the free end of the elastic telescopic block 188. After the free end of the elastic telescopic block 188 is separated from the contact with the free end of the elastic telescopic rod 184, the free end of the elastic telescopic block 188 moves to the left under the action of its own elastic force. The free end of the elastic telescopic block 188 moves to the left to limit the bottom of the free end of the elastic telescopic rod 184.
