Description

Technical Field

[0001] The present invention belongs to the technical field of air-conditioning air vents, and particularly relates to a rotatable and adjustable air vent with a purification function. Background Art

[0002] An air-conditioning air vent is the terminal device of an air-conditioning system, responsible for adjusting the air flow direction, air volume, and distribution pattern, and directly affecting the air supply efficiency and comfort. According to the structure and working principle, it is mainly divided into the following types: swirl air vent: inducing air mixing through rotating jets, with fast wind speed decay and long range, suitable for large spaces such as gymnasiums and exhibition halls; diffuser: installed on the ceiling, with uniform air flow diffusion and reduced wind sensation, suitable for places such as offices and medical facilities; self-acting variable flow type: automatically adjusting the air volume according to pressure to adapt to complex air flow requirements; nozzle: directional air supply, with long range and stable direction, mostly used for rapid temperature adjustment in large spaces such as airports and gymnasiums.

[0003] Currently, existing air vents generally only have the function of guiding the air flow direction. However, due to the presence of harmful substances such as dust in the air flow, the air vent needs to treat the harmful substances such as dust in the air flow when guiding the air flow to ensure the quality of the air flow. However, when using the photocatalyst catalytic technology to purify the air flow, since the air flow contains dust and grease, etc., when the dust and grease are mixed, they will adhere to the catalyst used in the photocatalyst catalytic technology, which will affect the quality of the air flow and cause peculiar smells in the air flow. And since the catalyst used in the photocatalyst catalytic technology is attached to the substrate through spraying or loading processes, it is impossible to remove the grease attached to the outer surface of the catalyst by physical wiping. Based on this, a rotatable and adjustable air vent with a purification function is proposed. Summary of the Invention

[0015] The beneficial effects of the present invention are as follows: 1. By the combined use of the air blowing mechanism and the liquid injection mechanism of the present invention, the liquid injection mechanism can inject a grease dissolving solution into the air blowing mechanism, and the airflow containing the grease dissolving solution can act on the filter screen and the purification net respectively, which is convenient for decomposing the grease attached to the filter screen and the purification net, avoiding the situation that the grease adheres to the purification net, resulting in the inability of the purification net to purify and decompose the airflow discharged by the air conditioning system, leading to more pollutants in the airflow and affecting the health and safety of indoor personnel.

Thus, it ensures the decomposition efficiency of the nano-titanium dioxide on the organic pollutants in the airflow. At the same time, it can blow the water attached to the purification net generated by the decomposition of the organic pollutants by the nano-titanium dioxide on the purification net away from the purification net, further ensuring the decomposition efficiency of the purification net on the organic pollutants in the airflow.

[0017] 3. By the combined use of the recovery pipe and the collection pipe, the recovery pipe will extract the dust, grease and water blown off from the purification net by the spray holes through the recovery holes, and inject the extracted dust, grease and water into the filtration chamber. The collection pipe will extract the dust and grease blown off from the filter net by the blowing holes through the collection holes, and inject the extracted dust and grease into the filtration chamber, and filter them through the porous filter cotton to ensure the cleanliness of the air flow extracted by the extraction pipe.

[0018] 4. By the combined use of the filter net, the purification net, the ultraviolet lamp and the grease dissolving solution, the present invention realizes the filtration of the air flow discharged from the air conditioning system, and can disinfect and purify the filtered air flow to ensure the cleanliness of the air flow discharged into the room, thereby providing good protection for the indoor personnel.

Detailed implementation manners

[0021] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following detailed implementation manners are only used to further illustrate the present application and cannot be understood as a limitation on the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown in the figure, a rotatable and adjustable air outlet with a purification function includes an air duct 1 and an air port 2 opened at the end of the air duct 1. A bolt hole is opened at one end of the air duct 1 away from the air port 2, which facilitates the fixed connection of the air duct 1 to the air conditioning system through bolts. An adjustment motor 4 is installed at the end of the air duct 1. The adjustment motor 4 is a servo motor that can rotate forward and backward. The output end of the adjustment motor 4 is fixedly connected to an adjustment plate 3. The adjustment plate 3 is attached to the inner surface of the air duct 1 and is adapted to the air port 2. It also includes: two groups of ultraviolet lamps 5 fixedly connected inside the air duct 1; a purification mechanism 8 fixedly connected inside the air duct 1. The purification mechanism 8 includes a purification net 804 and a filter screen 805. The purification net 804 is arranged in a honeycomb shape, and a nano-titanium dioxide catalyst is attached to the purification net 804 through spraying or loading technology. The purification net 804 is arranged between the two groups of ultraviolet lamps 5. A first fixing ring 6 that is rotatably connected to the purification net 804 is fixedly connected inside the air duct 1. Left water return ports 12 and right water return ports 14 are respectively opened on both sides of the bottom of the air duct 1 where the first fixing ring 6 is located. A second fixing ring 7 that is rotatably connected to the filter screen 805 is fixedly connected inside the air duct 1. A dust discharge port 13 is opened on the left side of the bottom of the air duct 1 where the second fixing ring 7 is located. The purification mechanism 8 also includes two fixing frames 801 fixedly connected inside the air duct 1. A driving motor 802 is fixedly connected to one of the fixing frames 801. The output end of the driving motor 802 is fixedly connected to a rotating shaft 803. The rotating shaft 803 is rotatably connected to the two fixing frames 801. Both the purification net 804 and the filter screen 805 are fixedly connected to the rotating shaft 803.

[0023] When the air conditioning system exhausts air, at this time, the opening size of the air port 2 is adjusted as needed. At this time, the adjustment motor 4 is started to make the adjustment plate 3 rotate, thereby changing the opening size of the adjustment air port 2. When it stops being used, the adjustment motor 4 is started to make the adjustment plate 3 block the air port 2, avoiding the reverse flow of indoor air into the air conditioning system, and thus preventing the poor-quality air in the room from entering the air conditioning system and polluting the air conditioning system. When exhausting air, at this time, the ultraviolet lamp 5 and the driving motor 802 are started. The driving motor 802 will drive the purification net 804 and the filter screen 805 to rotate through the rotating shaft 803. The gas discharged from the air conditioning system first passes through the filter screen 805 for filtration. After filtration, the gas passes through the catalyst on the purification net 804 and is purified by the ultraviolet lamp 5. The microorganisms in the air flow discharged from the air conditioning system are disinfected, and at the same time, the organic pollutants in the air flow discharged from the air conditioning system are decomposed into water and carbon dioxide, ensuring the cleanliness of the air flow discharged from the air conditioning system. Dust and other impurities in the gas discharged from the air conditioning system will adhere to the filter screen 805, and some of the un-decomposed grease will adhere to the purification net 804.

[0024] Such as Figure 2 、 Figure 4 、Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown in Figure 9 , Figure 10 , Figure 11 and Figure 12 , the adjustable air outlet further includes a cleaning mechanism 9 disposed on the air inlet side of the filter screen 805. The cleaning mechanism 9 includes a first bevel gear 901 fixedly connected to the outer surface of the rotating shaft 803. One side of one of the fixing frames 801 is fixedly connected with a fixing plate 905. A reciprocating lead screw 903 is rotatably connected through the fixing plate 905. The bottom of the reciprocating lead screw 903 is rotatably connected to the inner bottom of the air duct 1. The top of the reciprocating lead screw 903 is fixedly connected with a second bevel gear 902. The second bevel gear 902 meshes with the first bevel gear 901. A lifting plate 904 is threadedly connected through the reciprocating lead screw 903. One end of the lifting plate 904 is slidably connected to one of the fixing frames 801. The other end of the lifting plate 904 is fixedly connected with a cleaning pipe 906. The length of the reciprocating thread on the reciprocating lead screw 903 is lower than the maximum distance of the up and down movement of the cleaning pipe 906. A plurality of bristles 907 are fixedly connected to the side of the cleaning pipe 906 facing the filter screen 805, and the plurality of bristles 907 are in contact with the filter screen 805. An air blowing hole 908 is formed on the side of the cleaning pipe 906 facing the filter screen 805, and the air blowing hole 908 is disposed between the plurality of bristles 907.

[0025] When the rotating shaft 803 rotates, it will drive the first bevel gear 901 to rotate. The first bevel gear 901 will drive the reciprocating lead screw 903 to rotate through the second bevel gear 902. At this time, the lifting plate 904 will move up and down along the threaded outer surface of the reciprocating lead screw 903 under the limiting action of the fixing frame 801, thereby driving the cleaning pipe 906 to move up and down. At this time, since the plurality of bristles 907 are in contact with the filter screen 805 and the filter screen 805 is in a rotating state, the plurality of bristles 907 can clean the filter screen 805 in all directions, clean the dust adhered to the filter screen 805, and the dust cleaned from the filter screen 805 is discharged through the dust discharge port 13, reducing the probability of blockage of the filter screen 805, thereby ensuring the filtering efficiency and filtering quality of the filter screen 805 for the air flow discharged from the air conditioning system.

[0026] As Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 10 , Figure 11 , Figure 12 and Figure 13As shown in the figure, the adjustable air vent further includes: a blowing mechanism 10 fixedly connected to the inner bottom of the air duct 1. The blowing mechanism 10 includes a spray pipe 1006 disposed on the air intake side of the purification net 804. Spray holes 1007 are formed on the side of the spray pipe 1006 facing the purification net 804. The blowing mechanism 10 further includes an air pump 1001 fixedly connected to the inner bottom of the air duct 1. The exhaust end of the air pump 1001 is fixedly communicated with a blowing pipe 1002. The blowing pipe 1002 is in the form of a tee pipe. One end of the blowing pipe 1002 is fixedly communicated with the air pump 1001, the second end is fixedly communicated with the spray pipe 1006, and the third end is fixedly communicated with a cleaning pipe 906. The third end of the blowing pipe 1002 is in the form of a flexible pipe, which will not affect the normal up and down movement of the cleaning pipe 906. The air intake end of the air pump 1001 is fixedly communicated with an air extraction pipe 1003. The bottom of the air duct 1 is fixedly connected with a filter chamber 1004 by bolts. The filter chamber 1004 is fixedly communicated with the air extraction pipe 1003. A porous filter cotton 1005 is fixedly connected inside the filter chamber 1004. The bolted connection method facilitates the disassembly of the filter chamber 1004. The filter chamber 1004 is provided with three parts, namely an ash storage part, a filtering part, and a water storage part. The ash discharge port 13 is internally communicated with the ash storage part of the filter chamber 1004. The left water return port 12 and the right water return port 14 are internally communicated with the water storage part of the filter chamber 1004. The air extraction pipe 1003 is internally communicated with the filtering part of the filter chamber 1004, so as to facilitate the replacement of the porous filter cotton 1005 inside it, and the dumping of the dust and liquid generated by the filtration of the porous filter cotton 1005 inside it. The top of the filter chamber 1004 is fixedly communicated with a recovery pipe 1008. Recovery holes 1009 are formed on the recovery pipe 1008. The recovery holes 1009 are disposed opposite to the other side of the purification net 804. The recovery holes 1009 are disposed opposite to the spray holes 1007. The top of the filter chamber 1004 is fixedly connected with a collection pipe 1010. The recovery pipe 1008 and the collection pipe 1010 are internally communicated with the filtering part of the filter chamber 1004. Collection holes 1011 are formed on the collection pipe 1010. The air blowing holes 908 are disposed opposite to the collection holes 1011. The collection holes 1011 are disposed opposite to the exhaust side of the filter screen 805.

[0027] When the air conditioner system exhausts air, the air pump 1001 is started, so that the air pump 1001 extracts the internal gas of the filter chamber 1004 through the extraction pipe 1003. The gas extracted by the air pump 1001 will be discharged through the blowing pipe 1002. At this time, since the blowing pipe 1002 is set in the form of a tee pipe, a part of the airflow discharged from the blowing pipe 1002 enters the jet pipe 1006, and the other part enters the cleaning pipe 906. The airflow entering the jet pipe 1006 will blow towards the purification net 804 through the jet holes 1007. And during this process, the purification net 804 is in a rotating state under the action of the rotating shaft 803. Therefore, it is possible to blow air on various parts of the purification net 804, remove the dust and grease adhered to the purification net 804, so that the dust and grease can fall off from the purification net 804, and avoid the situation that the airflow discharged from the air conditioner system cannot contact the nano-titanium dioxide adhered to the outer surface of the purification net 804, resulting in the inability of the nano-titanium dioxide to decompose the organic pollutants in the airflow discharged from the air conditioner system. Thus, the decomposition efficiency of the nano-titanium dioxide for the organic pollutants in the airflow discharged from the air conditioner system is ensured. At the same time, the water adhered to the purification net 804 generated by the decomposition of the organic pollutants by the nano-titanium dioxide adhered to the purification net 804 can be blown away from the purification net 804, further ensuring the decomposition efficiency of the purification net 804 for the organic pollutants in the airflow discharged from the air conditioner system; The airflow entering the cleaning pipe 906 will act on the filter screen 805 through the blowing holes 908, and blow away the dust and grease brushed off the filter screen 805 by the bristles 907 from the filter screen 805 and the bristles 907; And during this process, since the extraction pipe 1003 extracts the internal gas of the filtering part of the filter chamber 1004, and the recovery pipe 1008 and the collection pipe 1010 are communicated with the inside of the filtering part of the filter chamber 1004, the recovery pipe 1008 will extract the dust, grease and water blown off from the purification net 804 by the jet holes 1007 through the recovery holes 1009, and inject the extracted dust, grease and water into the filtering part of the filter chamber 1004 for filtration by the porous filter cotton 1005. The collection pipe 1010 will extract the dust and other impurities that can pass through the filter screen 805 and are blown off from the filter screen 805 by the blowing holes 908 through the collection holes 1011, and inject the extracted dust and other impurities into the filtering part of the filter chamber 1004 for filtration by the porous filter cotton 1005, ensuring the cleanliness of the airflow extracted by the extraction pipe 1003.

[0028] Such as Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 11 and Figure 13As shown in the figure, the adjustable air vent further includes a liquid injection mechanism 11 fixedly connected to the inner bottom of the air duct 1. After the liquid injection mechanism 11 injects a grease-dissolving solution into the air blowing mechanism 10, the spray holes 1007 spray the grease-dissolving solution onto the purification net 804. The liquid injection mechanism 11 includes a liquid tank 1101 fixedly connected to the inner bottom of the air duct 1. The liquid tank 1101 is filled with a grease-dissolving solution (this solution can be citrus solution, biological enzyme cleaner, soapy water / plant-based detergent, etc.). The top of the liquid tank 1101 is fixedly connected to a liquid adding pipe 1102. The end of the liquid adding pipe 1102 is equipped with a sealing plug. The inner surface of the liquid tank 1101 is fixedly connected to a partition 1103. The bottom of the partition 1103 is fixedly connected to a liquid pump 1104. The liquid pump 1104 is fixedly connected to the bottom of the liquid tank 1101. The bottom of the liquid tank 1101 is fixedly connected to a liquid injection pipe 1105 communicating with the inside of the liquid pump 1104. The liquid injection pipe 1105 is fixedly connected to the air blowing pipe 1002. The inner surface of the liquid injection pipe 1105 is fixedly connected to a liquid spraying plate 1106.

[0029] When the air conditioner system exhausts air, the liquid pump 1104 is started regularly, or when the air conditioner system stops working and needs to be cleaned, the liquid pump 1104 is started. The operation of the liquid pump 1104 will cause the grease-dissolving solution in the liquid tank 1101 to enter the liquid injection pipe 1105. The grease-dissolving solution is atomized through the liquid spraying plate 1106. The atomized grease-dissolving solution will enter the air blowing pipe 1002 through the liquid injection pipe 1105. The grease-dissolving solution entering the air blowing pipe 1002 will enter the cleaning pipe 906 and the air spraying pipe 1006 along with the air flow, and is blown onto the filter screen 805 and the purification net 804 through the air blowing holes 908 and the spray holes 1007 respectively. The air flow containing the grease-dissolving solution can decompose the grease attached to the filter screen 805 and the purification net 804, avoiding the influence of grease attachment on the filtration and purification efficiency of the air flow discharged from the air conditioner system, thereby ensuring the purification quality of the air flow discharged from the air conditioner system.

[0030] The specific working principle of the present invention is as follows: When the air conditioner system exhausts air, the opening size of the air port 2 is adjusted as needed at this time. The adjusting motor 4 is started to rotate the adjusting plate 3, thereby changing the opening size of the adjusting air port 2. At the same time, the ultraviolet lamp 5, the driving motor 802 and the air pump 1001 are started. The driving motor 802 will drive the purification net 804 and the filter screen 805 to rotate through the rotating shaft 803. The gas discharged from the air conditioner system first passes through the filter screen 805 for filtration. After filtration, the catalyst on the purification net 804 cooperates with the ultraviolet lamp 5 to purify the air flow discharged from the air conditioner system, disinfect the microorganisms in the air flow discharged from the air conditioner system, and decompose the organic pollutants in the air flow discharged from the air conditioner system into water and carbon dioxide at the same time. The generated water will be discharged into the water storage part of the filter chamber 1004 through the left water return port 12 and the right water return port 14 to ensure the cleanliness of the air flow discharged from the air conditioner system; dust and other impurities in the gas discharged from the air conditioner system will adhere to the filter screen 805, and some of the undegraded grease will adhere to the purification net 804; During this process, when it is necessary to regularly clean the filter screen 805 and the purification net 804, the liquid pump 1104 is started. The operation of the liquid pump 1104 will cause the grease-dissolving solution in the liquid tank 1101 to enter the liquid injection pipe 1105, and the grease-dissolving solution is atomized through the liquid spraying plate 1106. The atomized grease-dissolving solution will enter the air blowing pipe 1002 through the liquid injection pipe 1105. For the grease-dissolving solution that enters the air blowing pipe 1002, the air pump 1001 extracts the internal gas of the filtering part of the filtering chamber 1004 through the air extraction pipe 1003. The gas extracted by the air pump 1001 will be discharged through the air blowing pipe 1002. When discharging through the air blowing pipe 1002, it will carry the atomized grease-dissolving solution. At this time, since the air blowing pipe 1002 is set in the form of a tee pipe, a part of the airflow discharged from the air blowing pipe 1002 enters the air spraying pipe 1006, and the other part enters the cleaning pipe 906. The airflow that enters the air spraying pipe 1006 will blow towards the purification net 804 through the spray holes 1007. And during this process, the purification net 804 is in a rotating state under the action of the rotating shaft 803. Therefore, it can blow air on various parts of the purification net 804 to remove the dust and grease adhering to the purification net 804, avoiding the situation that the airflow discharged from the air-conditioning system cannot contact the nano-titanium dioxide attached to the outer surface of the purification net 804, resulting in the inability of the nano-titanium dioxide to decompose the organic pollutants in the airflow discharged from the air-conditioning system. Thus, it ensures the decomposition efficiency of the nano-titanium dioxide for the organic pollutants in the airflow discharged from the air-conditioning system. At the same time, it can blow away the water adhering to the purification net 804 generated by the decomposition of the organic pollutants by the nano-titanium dioxide attached to the purification net 804, further ensuring the decomposition efficiency of the purification net 804 for the organic pollutants in the airflow discharged from the air-conditioning system. And the airflow that enters the cleaning pipe 906 will act on the filter screen 805 through the air blowing holes 908, blowing away the dust and other impurities on the filter screen 805 and the brush bristles 907, and dissolving the grease on the filter screen 805 and the brush bristles 907 with the grease-dissolving solution, avoiding the influence of the adhesion of grease on the filtering and purification efficiency of the airflow discharged from the air-conditioning system, thereby ensuring the purification quality of the airflow discharged from the air-conditioning system; And during this process, since the extraction pipe 1003 extracts the gas inside the filtration chamber 1004, and the recovery pipe 1008 and the collection pipe 1010 are in communication with the inside of the filtration chamber 1004, the recovery pipe 1008 will extract the dust blown off from the purification net 804 by the spray holes 1007, the grease and water dissolved by the grease-dissolving solution, and part of the grease-dissolving solution through the recovery holes 1009, and inject the extracted dust, the grease and water dissolved by the grease-dissolving solution, and part of the grease-dissolving solution into the filtration part of the filtration chamber 1004 for filtration through the porous filter cotton 1005. The collection pipe 1010 will extract the dust that can pass through the filter net 805 and the grease dissolved by the grease-dissolving solution and part of the grease-dissolving solution blown off from the filter net 805 by the air blowing holes 908 through the collection holes 1011, and inject the extracted dust, the grease dissolved by the grease-dissolving solution, and part of the grease-dissolving solution into the filtration part of the filtration chamber 1004 for filtration through the porous filter cotton 1005, ensuring the cleanliness of the air flow extracted by the extraction pipe 1003; During the process of the air flow being blown out from the air blowing holes 908, the rotation of the rotating shaft 803 will drive the first bevel gear 901 to rotate. The first bevel gear 901 will drive the reciprocating lead screw 903 to rotate through the second bevel gear 902. At this time, the lifting plate 904 will move up and down along the outer surface of the thread of the reciprocating lead screw 903 under the limiting action of the fixing frame 801, thereby driving the cleaning pipe 906 to move up and down. At this time, since multiple brush hairs 907 are in contact with the filter net 805 and the filter net 805 is in a rotating state, the multiple brush hairs 907 can clean the filter net 805 in all directions, cleaning the dust adhered to the filter net 805. The dust cleaned from the filter net 805 is discharged into the ash storage part of the filtration chamber 1004 through the ash discharge port 13, reducing the probability of blockage of the filter net 805, thereby ensuring the filtration efficiency and filtration quality of the filter net 805 for the air flow discharged from the air conditioning system. After the cleaning is completed, the air pump 1001 and the liquid pump 1104 are turned off; When the air conditioning system stops being used, turn off the ultraviolet lamp 5 and the drive motor 802, and start the adjustment motor 4 so that the adjustment plate 3 blocks the air port 2, avoiding the reverse flow of the indoor air flow into the air conditioning system, thereby preventing the poor-quality air flow in the room from entering the air conditioning system and polluting the air conditioning system.
