Description

Technical Field

[0001] The present invention relates to the technical field of air detection equipment, and in particular to an air quality detector. Background Art

[0002] An air quality detector is a device used to monitor and evaluate air quality. It mainly measures various harmful substances in the air, such as particulate matter, gaseous pollutants, microorganisms, etc., through sensors to judge the air quality. These detectors can conduct real-time monitoring of air quality at the individual, community, or even regional levels, and usually have the ability to detect several basic air pollutant parameters in the environment, such as sulfur dioxide, nitrogen dioxide, ozone, carbon monoxide, PM10, PM2.5, etc.

[0003] Chinese Patent CN202211061766.1 discloses an air quality detector, which includes a filter box. A bracket is installed below the filter box, and an air quality detector is installed on the lower side of the filter box. A filter box body is arranged inside the filter box, and an air inlet dust removal device is installed inside the filter box body. A dust removal mechanism is arranged inside the air inlet dust removal device, an air inlet fan device is installed in the middle of the dust removal mechanism, a slide bar is arranged inside the dust removal mechanism, a moving slider is arranged above the slide bar, a dust removal frame is connected above the moving slider, a connecting flange is connected above the dust removal frame, a dust removal brush is connected to the outside of the dust removal frame, a limiting block is arranged inside the dust removal frame, a reinforcing rib is welded to the outside of the limiting block, and a dust removal outer frame is installed inside the reinforcing rib. Through the dust removal device, the dust removal brush is attached to the inner wall of the box. When the dust removal device starts to work, the dust removal brush removes the dust remaining in the gas detected in the box this time to ensure that there is no error in the next gas detection and the data is more accurate.

[0004] However, the dust removal effect of this technical solution is poor. The cleaning method using a single dust removal brush is blocked by the filter structure of the box and cannot achieve good results in actual use. Especially in outdoor air quality detection operations, objects with larger volumes affected by wind force in the external environment (such as leaves, plastic packaging, etc.) are likely to enter the device, thereby further hindering the dust removal effect.

[0012] The dust prevention mechanism further includes a torsion seat arranged on one side of the winding bearing. A torsion spring is installed inside the torsion seat. Torsion arms are arranged at both ends of the torsion spring.

[0013] The driving mechanism includes a structural vertical plate arranged on the top of the protection cylinder cover. A motor support plate is installed on one side of the structural vertical plate. A driving motor is installed on the top of the motor support plate. Multiple assembly bolts are threadedly connected to one side of the motor support plate. A driving rotating shaft is movably connected inside the protection cylinder body. Two double driving wheels are fixedly connected to the outer side of the driving rotating shaft. Multiple concave blocks are arranged on the outer sides of the double wheels of the two double driving wheels. A driving cam is fixedly connected to the top of the driving rotating shaft. A docking shaft is fixedly connected to the center of the top of the driving cam. A coupling is arranged at the bottom of the output shaft of the driving motor. A camshaft is further arranged on the top of the driving cam. A cam rod is movably connected to the outer side of the camshaft.

[0014] The jet mechanism includes an inflation cylinder provided at the top of the protective cylinder cover. A cylinder assembly plate is provided on the outer side of one end of the inflation cylinder. An inflation piston is movably connected inside the inflation cylinder.

[0015] The jet mechanism includes a one-way inner tube penetrating and connecting to the bottom of the inner partition. Multiple air outlet grooves are formed on the outer wall of the one-way inner tube. A structural inner ring is fixedly connected to the inner wall of the one-way inner tube.

[0016] A conical cap penetrates and connects to the bottom of the protective cylinder cover. Multiple connecting rods are provided at the top of the conical cap.

[0017] The usage method of this air quality detector includes the following steps:

[0018] When dust removal is required in the space inside the protective cylinder body, the user reversely drives the drive motor. When the drive motor is powered on and starts, it will drive the two double drive wheels on the drive cam and the drive rotating shaft to reverse through the coupling. When the double drive wheels reverse, they drive the filter net to move along the limit bottom groove rings at both ends of the protective cylinder body and enter the winding drum through the engagement of the concave blocks with the filter holes on the filter net. When passing through the material receiving cover, the two outer scraping blades can scrape off the impurities adhered to the filter net, and further clean them through multiple wire brushes. The filter net will be wound around the winding rotating shaft under the influence of the return torque of the torsion spring in the torsion seat on the winding rotating shaft, making the protective cylinder body unobstructed and facilitating subsequent dust removal.

[0019] During the rotation of the driving cam, the connection between the cam rod on the camshaft and the inflation piston will drive the inflation piston to reciprocate and move back and forth in the inflation cylinder. When moving backward, the volume inside the cylinder increases and the air pressure decreases, so the external air pressure will overcome the valve in the intake pipe and enter the cylinder body. When moving forward, the volume decreases, and the internal air pressure can overcome the valve in the exhaust pipe and inject the air in the inflation cylinder into the upper end of the air storage cavity in the jet seat. When the air pressure at the upper end is sufficient to overcome the retraction force of the retraction spring ring in the one-way inner tube, the movable plate will be driven by the air pressure to drive the movable sealing ring away from the sealing ring, further making the air outlet groove unblocked. The high-pressure air will be ejected from multiple air nozzles and blown into the protective cylinder body for dust removal after being guided by the conical cap. Thus, through the above series of continuous structural settings, efficient dust removal can be carried out, and large impurities can be avoided from affecting the dust removal effect during dust removal;

[0020] After the dust removal is completed, the user can drive the driving motor forward to drive the filter net to be laid again through the forward rotation of the double driving wheels to ensure subsequent use.

[0021] The beneficial effects of the present invention are as follows:

[0022] (1) The present invention protects the air detector through the protective cylinder body, and installs and lays the filter net through the groove ring and the limiting structure on the cylinder body. The filter holes on the filter net can effectively filter and block large impurities in the environment, and at the same time do not affect the intake air and the use of the detector.

[0023] (2) The present invention drives the forward and reverse rotation of the double driving wheels on the driving rotating shaft through the driving motor to realize the forward and reverse driving of the filter net. During driving, the filter net is automatically wound and laid in cooperation with the torsion spring in the winding mechanism, so as to create a dust removal environment and ensure that the dust in the protective cylinder body can be discharged without being affected.

[0024] (3) The present invention sets the scraping blade and the steel wire brush on the material receiving cover to be close to the filter net. When the filter net moves, the net body and the filter holes can be automatically cleaned, effectively avoiding impurities from adhering to the net body and affecting subsequent detection of intake air, and at the same time avoiding the occurrence of blockage caused by impurities entering the winding structure.

[0025] (4) The present invention drives the rotation of the cam through the driving motor to drive the inflation piston to reciprocate. Through the change of the internal and external air pressure difference and the setting of the valves in the air inlet and outlet pipes, the jet seat can be inflated cyclically. And through the setting of the one-way inner tube on the inner partition plate in the jet seat, the air in the air storage cavity is pressurized, so that high-pressure air is ejected from the air nozzles to carry out dust removal while the filter net is wound and laid, and the overall dust removal effect of the device is effectively improved.

[0026] In summary, the present invention has the advantages of high automation degree and obvious dust removal effect. Description of the Drawings

Thus, during laying, the torsion spring 713 twists in the rotation mode of the winding shaft 703, and then generates a return torsion force to tighten the net body when winding the filter net 705, ensuring the winding effect.

[0058] The driving mechanism 9 includes a structural vertical plate 901 provided on the top of the protective cylinder cover 606. A motor support plate 902 is installed on one side of the structural vertical plate 901. A driving motor 903 is installed on the top of the motor support plate 902.

[0059] Among them, the structural vertical plate 901 provides support for the motor support plate 902 and the inflatable cylinder 1001; when the driving motor 903 is powered on, it can drive the two groups of double driving wheels 906 and the driving cam 908 on the driving rotating shaft 905 to rotate through the connection of the coupling 910 and the docking shaft 909.

[0060] The jetting mechanism 10 includes an inflatable cylinder 1001 arranged on the top of the protective cylinder cover 606. A cylinder assembly plate 1002 is arranged on the outer side of one end of the inflatable cylinder 1001. An inflatable piston 1003 is movably connected inside the inflatable cylinder 1001.

An inner partition plate 1008 is installed inside the air storage cavity 1007. A plurality of air nozzles 1009 are arranged at the bottom of the jetting seat 1006.

[0061] Among them, the inflatable cylinder 1001 is fixed through the cylinder assembly plate 1002, intakes air through the air inlet pipe 1004, and discharges air through the air outlet pipe 1005. When the piston moves, the volume inside the cylinder can be compressed, so that the gas can be injected into the jetting seat 1006 and then ejected as high-speed air flow by the plurality of air nozzles 1009 to jet and remove dust from the space inside the cylinder.

[0062] The jetting mechanism 10 includes a one-way inner pipe 1010 penetrating and connected to the bottom of the inner partition plate 1008. A plurality of air outlet grooves 1011 are arranged on the outer wall of the one-way inner pipe 1010. A structural inner ring 1012 is fixedly connected to the inner wall of the one-way inner pipe 1010. A retraction spring ring 1013 is fixedly connected to the bottom of the structural inner ring 1012. A structural sealing ring 1014 is also fixedly connected to the inner wall of the one-way inner pipe 1010. A plurality of structural blocks 1015 are arranged on the top of the structural sealing ring 1014. A sealing ring 1016 is arranged at the bottom of the structural sealing ring 1014. The bottom end of the retraction spring ring 1013 is fixedly connected to a movable plate 1017. A movable sealing ring 1018 is arranged on the top of the movable plate 1017. A plurality of guiding sliding blocks 1019 are arranged on the outer wall of the movable plate 1017.

[0063] Among them, the retraction tension of the retraction spring ring 1013 in the one-way inner tube 1010 is applied to the movable plate 1017 and the movable sealing ring 1018, and the sealing is achieved by pressing the sealing ring 1016. When the air pressure in the upper half layer of the jet seat 1006 is large enough to overcome the return tension of the spring, the movable sealing ring 1018 will be pushed open under the influence of the internal and external air pressure difference, and multiple groups of air outlet grooves 1011 will be unblocked to achieve air outlet, ensuring the jet air pressure. Among them, multiple groups of guide sliders 1019 can be movably connected with multiple groups of guide chutes 1020, so as to limit and guide the movable plate 1017 and ensure its stability during movement.

[0064] The bottom of the protective cylinder cover 606 is connected through a conical cap 11, and multiple groups of connecting rods 12 are arranged on the top of the conical cap 11.

[0065] Among them, the conical cap 11 is installed in the protective cylinder body 601 through multiple groups of connecting rods 12, so as to guide the airflow during jetting and improve the dust removal effect.

[0066] Working principle:

[0067] When the space in the protective cylinder body 601 needs to be dusted, the user reversely drives the drive motor 903. The drive motor 903 is powered on and starts to drive the two double drive wheels 906 on the drive cam 908 and the drive rotating shaft 905 to reverse through the coupling 910. When the double drive wheels 906 reverse, they drive the filter net 705 to move along the limit bottom groove ring 603 at both ends of the protective cylinder body 601 and enter the winding drum 701 through the engagement of the concave block 907 with the filter holes 706 on the filter net 705. When passing through the material receiving cover 707, the two outer scraping blades 709 can scrape off the impurities adhered to the filter net 705, and further clean them through multiple groups of wire brushes 711. The filter net 705 is affected by the return torque of the torsion spring 713 in the torsion seat 712 on the winding rotating shaft 703 and will be wound around the winding rotating shaft 703 for winding, making the protective cylinder body 601 unblocked and facilitating subsequent dust removal;

[0068] During the rotation of the driving cam 908, the connection between the cam rod 912 on the camshaft 911 and the inflation piston 1003 will drive the inflation piston 1003 to reciprocate and move back and forth within the inflation cylinder 1001. When moving backward, the volume inside the cylinder increases and the air pressure decreases, so the external air pressure will overcome the valve in the intake pipe 1004 and enter the cylinder. When moving forward, the volume decreases, and the internal air pressure can overcome the valve in the outlet pipe 1005 to inject the air in the inflation cylinder 1001 into the upper end of the air storage cavity 1007 in the jet seat 1006. When the air pressure at the upper end is sufficient to overcome the retraction force of the retraction spring ring 1013 in the one-way inner tube 1010, the movable plate 1017 will be driven by the air pressure to drive the movable sealing ring 1018 away from the sealing ring 1016, further making the air outlet groove 1011 unobstructed. The high-pressure air will be ejected from the multiple air nozzles 1009 and blown into the protective cylinder 601 for dust removal after being guided by the conical cap 11. Thus, through the above series of continuous structural settings, efficient dust removal can be carried out, and large impurities can be avoided from affecting the dust removal effect during dust removal;

[0069] After the dust removal is completed, the user can drive the driving motor 903 forward to drive the filter screen 705 to be laid again through the forward rotation of the double driving wheels 906 to ensure subsequent use.

[0070] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

10. An air quality detector according to claim 9, characterized in that, The usage method of the air quality detector includes the following steps: When dust removal is required in the space of the protective cylinder body (601), the user reversely drives the driving motor (903). The driving motor (903) is powered on and starts to drive the two double driving wheels (906) on the driving cam (908) and the driving rotating shaft (905) to reverse through the coupling (910). When the double driving wheels (906) reverse, they drive the filter net (705) to move along the limiting bottom groove ring (603) at both ends of the protective cylinder body (601) and enter the winding cylinder (701) through the engagement of the concave block (907) and the filter holes (706) on the filter net (705). When passing through the material receiving cover (707), the two scraping blades (709) on the outside can scrape off the impurities adhered to the filter net (705), and further clean them through multiple groups of wire brushes (711). Affected by the return torque of the torsion spring (713) in the torsion seat (712) on the winding rotating shaft (703), the filter net (705) will be wound around the winding rotating shaft (703) for winding, making the protective cylinder body (601) unobstructed and facilitating subsequent dust removal; During the rotation of the driving cam (908), the connection between the cam rod (912) on the camshaft (911) and the inflating piston (1003) will drive the inflating piston (1003) to reciprocate and telescopically move in the inflating cylinder (1001). When moving backward, the volume inside the cylinder increases and the air pressure decreases, so the external air pressure will overcome the valve in the air inlet pipe (1004) and enter the cylinder. When moving forward, the volume decreases, and the internal air pressure can overcome the valve in the air outlet pipe (1005) to inject the air in the inflating cylinder (1001) into the upper end of the air storage cavity (1007) of the jet seat (1006). When the air pressure at the upper end is sufficient to overcome the retraction force of the retraction spring ring (1013) in the one-way inner pipe (1010), the movable plate (1017) is driven by the air pressure to drive the movable sealing ring (1018) away from the sealing ring (1016), further making the air outlet groove (1011) unobstructed. The high-pressure air will be ejected from multiple air nozzles (1009), and after being guided by the conical cap (11), it will be blown into the protective cylinder body (601) for dust removal. Thus, through the above series of continuous structural settings, efficient dust removal can be carried out, and large-sized impurities can be avoided from affecting the dust removal effect during dust removal; After the dust removal is completed, the user can drive the driving motor (903) forward to drive the filter net (705) to be laid again through the forward rotation of the double driving wheels (906) to ensure subsequent use.
