Description

Technical Field

[0001] The invention relates to the technical field of formaldehyde detection, and in particular to a device for detecting formaldehyde in an indoor environment. Background Art

[0002] With the continuous progress and development of society, more and more residential areas and commercial buildings are being built, and people have higher requirements for the style and environment of interior decoration. Then the pollution of decoration materials after interior decoration is also the focus of people's attention. Indoor pollutants are mainly divided into four types: formaldehyde, benzene, ammonia and radon. Among them, formaldehyde ranks second on the priority control list of toxic chemicals in China. It has been identified as a carcinogen and teratogen by the World Health Organization. Formaldehyde mainly comes from indoor building materials and furniture. Long-term exposure to low doses of formaldehyde can cause various chronic respiratory diseases, cause memory and intelligence decline in adolescents, cause nasopharyngeal cancer, colon brain tumors, nuclear gene mutations, inhibition of DNA damage repair, menstrual disorders, pregnancy syndrome, newborn chromosome abnormalities, and even leukemia. Among those who are exposed, children, pregnant women and the elderly are particularly sensitive to formaldehyde, and the harm is greater. Therefore, it can be seen that indoor air quality testing and formaldehyde concentration testing are very important. Formaldehyde testing refers to the quantitative detection of formaldehyde contained in air, water, food, clothing, boards, leather, etc. through specific methods or instruments. White or wrinkle-free clothing, especially some jeans, clothes and pants that claim to be 100% wrinkle-proof and shrink-proof, or all-cotton wrinkle-free shirts that use glyoxal resin for shaping, all contain formaldehyde. Formaldehyde has a strong irritating effect on human skin and can cause skin eczema and systemic allergies. However, it is not easy to adjust the equipment after the test is completed, and the air at different heights cannot be collected, which can easily lead to errors in the test results, reducing the accuracy of the equipment detection, and the equipment is prone to collision and damage when placed.

[0003] In summary, it is not easy to adjust the equipment after the equipment inspection is completed, and the air at different heights cannot be collected, which can easily lead to errors in the test results, reduce the accuracy of the equipment inspection, and the equipment is prone to collision and damage when placed.

[0020] 5. The indoor environment formaldehyde detection device can be supported inside the sealed shell by an internal support frame, thereby increasing the strength of the sealed shell itself, making it easier for the photocatalytic decomposition component inside the sealed shell to process the air after detection, thereby avoiding the situation where formaldehyde is contained in the subsequently discharged air. The baffle frames are evenly distributed inside the sealed shell and contact the photocatalytic decomposition component, making it easier for the baffle frames to move on the sealed shell with the flow of air, thereby preventing the photocatalytic decomposition component from being displaced and tilted inside the sealed shell.

[0021] 6. The indoor formaldehyde detection device has grooves on the surface of the barrier disk, which can limit the flow of air entering the assembly cylinder through the barrier disk, thereby avoiding the situation where too much air enters the assembly cylinder and causes omissions in the detection of the detector. The filter plate inside the inner partition shell can filter the air circulation, so that the impurities contained in the air can be reduced during the circulation of the air through the inner partition shell, thereby avoiding the situation where the collection device on the surface of the filter plate is blocked by excessive impurities.

[0022] 7. The indoor formaldehyde detection device can generate heat through the heating tube inside the supporting shell, which is convenient for heat transfer when the supporting shell is connected to the protective ring, so that the heat can keep the inside of the activated carbon placement box dry, avoiding the influence of moisture on the adsorption efficiency of the activated carbon when the activated carbon is used. The activated carbon placed inside the activated carbon placement box purifies the air circulating after the detection through the protective ring, so that the activated carbon can cooperate with the photocatalytic decomposition component, thereby improving the air treatment quality.

The inner surface of the sealing ring 5 is slidably connected with a detection tube 6. The two ends of the detection tube 6 extend to the outside of the sealing ring 5. The top left side of the placing platform 4 is fixedly connected with a controller 7. The bottom of the placing platform 4 is fixedly connected to the chassis 2 and is evenly distributed on the chassis 2 through the moving wheels 1, so that the moving wheels 1 can adjust the placement position of the chassis 2, which is convenient for the staff to find a suitable position to place the equipment. The sealing ring 5 can seal the lifting position of the detection tube 6 inside the chassis 2 on the placing platform 4 to prevent dust from adhering to the gap between the sealing ring 5 and the placing platform 4, thereby ensuring the cleanliness of the connection position of the sealing ring 5. After the chassis 2 is detected through the exhaust duct 3, the air is discharged and the detection tube 6 can be stored when not in use. The detection tube 6 that is convenient to enter the inside of the chassis 2 cooperates with the placing platform 4 to place debris, thereby reducing the overall footprint of the equipment.

The middle position of the top of the inner cavity of the collecting shell 61 is rotatably connected with a collecting fan 62. The collecting fan 62 is driven by the motor to rotate inside the collecting shell 61, so that the air is collected by the collecting shell 61. The collected air enters the treatment cylinder 64 and directly contacts the detector 63 to detect the formaldehyde in the air. The detected data is transmitted to the controller 7 through the detector 63, which is convenient for the staff to observe the data through the controller 7. The rotation of the collecting fan 62 can collect the air around the middle position of the collection, thereby avoiding the problem of missing during the air collection process.

[0038] The hydraulic rod 67 has an abutment plate and a guide seat 65 installed on the top of the hydraulic rod 67. The bottom end of the guide seat 65 is connected to the processing cylinder 64. The outer surface of the guide seat 65 is slidably connected with a cleaning frame 66. The top of the cleaning frame 66 is fixedly connected to the placement platform 4. The hydraulic rod 67 is evenly distributed on the guide seat 65, so that the extension and retraction of the hydraulic rod 67 inside the chassis 2 drives the processing cylinder 64 to perform vertical lifting and lowering movements through the guide seat 65, which is convenient for adjusting the height of the collection shell 61, so that the collection shell 61 is at different heights to collect and detect air at different positions, which is convenient for the staff to compare the detection data at different heights, thereby improving the accuracy of the overall detection of the equipment, thereby reducing the overall detection error of the equipment, and when the collection shell 61 descends with the hydraulic rod 67, its surface can be cleaned through the cleaning frame 66, which is convenient for cleaning its surface, and the collection shell 61 enters the interior of the chassis 2 to protect it, thereby avoiding the collection shell 61 from being damaged due to collision when the equipment is not in use.

[0039] Among them, the processing cylinder 64 includes a blocking disk 641, the bottom of the blocking disk 641 is fixedly connected to the assembly cylinder 642, the bottom of the inner cavity of the assembly cylinder 642 is fixedly connected to the inner partition shell 643, and the top of the inner surface of the inner partition shell 643 is slidably connected to the filter screen plate 644. The air circulation inside the inner partition shell 643 can be filtered through the filter screen plate 644, so that the impurities contained in the air can be reduced during the circulation of the air through the inner partition shell 643, and the filter screen plate 644 can be tilted inside the inner partition shell 643 with the pressure of the air when the air is circulating, thereby generating a movable space with the inner partition shell 643, thereby avoiding the situation where the collection device on the surface of the filter screen plate 644 is blocked by excessive impurities. The bottom of the outer surface of the inner partition shell 643 is connected to a storage rack 645, and the storage rack 645 passes through the assembly cylinder 642 and extends to the outside of the assembly cylinder 642 at a position away from the inner partition shell 643. The surface of the blocking disk 641 has a groove, so that it can limit the flow of air entering the assembly cylinder 642 through the blocking disk 641, thereby avoiding the situation where too much air enters the assembly cylinder 642 and causes omissions in the detection of the detector 63. The assembly cylinder 642 cooperates with the blocking disk 641, so that it has good sealing properties and prevents air leakage on the assembly cylinder 642. The assembly cylinder 642 can support the blocking disk 641 so that it can maintain a horizontal state.

[0040] The guide seat 65 includes a sealing shell 651, the bottom of the inner cavity of the sealing shell 651 is fixedly connected with an inner support frame 652, and the inner surface of the inner support frame 652 is fixedly connected with a photocatalytic decomposition component 654. The inner support frame 652 can support the sealing shell 651 inside, thereby increasing the strength of the sealing shell 651 itself. At the same time, the installation of the inner support frame 652 inside the sealing shell 651 can play a limiting role. The connection between the sealing shell 651 and the assembly cylinder 642 facilitates the photocatalytic decomposition component 654 inside the sealing shell 651 to process the detected air, thereby avoiding the situation where formaldehyde is contained in the subsequently discharged air. The top of the photocatalytic decomposition component 654 The baffle frame 653 is evenly distributed inside the sealing shell 651 and contacts the photocatalytic decomposition component 654, so that the baffle frame 653 can be driven by the flow of air to move on the sealing shell 651, so that the baffle frame 653 can cooperate with the inner support frame 652, thereby increasing the stability of the photocatalytic decomposition component 654 itself and preventing the photocatalytic decomposition component 654 from being displaced and tilted inside the sealing shell 651. A contact ring 655 is fixedly connected to the top of the outer surface of the sealing shell 651.

The limiting arc plate 662 is inside the fixed shell 661, and the telescopic range of the cleaning rod 663 can be adjusted to increase the contact area of ​​the cleaning rod 663 inside the fixed shell 661. When the cleaning rod 663 moves, the clamping ring 664 can be used to remove dust adhered to its surface, thereby reducing the impact on the equipment during subsequent use. The limiting arc plate 662 cooperates with the clamping ring 664 to support the fixed shell 661, thereby increasing the strength of the fixed shell 661 itself, and the clamping ring 664 is far away. The cleaning rod 663 is fixedly connected to the fixed shell 661. The cleaning rod 663 itself has a spring and is evenly distributed on the clamping ring 664. When the collecting shell 61 is raised or lowered to contact the cleaning rod 663, the cleaning rod 663 can wipe its surface. When the cleaning rod 663 is subjected to the pressure of the collecting shell 61, it can shrink slightly to move on the clamping ring 664. At the same time, there is a space for dust to fall between the clamping ring 664 and the collecting shell 61, so that the cleaned dust can fall into the inside of the chassis 2, thereby avoiding dust splashing when cleaning the outside of the chassis 2. The cleaning rod 663 cleans the collecting shell 61 to prevent the surface of the collecting shell 61 from being blocked by dust. The bottom of the fixed shell 661 is fixedly connected with a reinforcement frame 665.

[0042] When in use, the chassis 2 is moved to a suitable position by the moving wheel 1 and then stopped. The hydraulic rod 67 is extended inside the chassis 2 to push the sealing shell 651 to rise. The sealing shell 651 drives the collecting shell 61 to rise gradually away from the chassis 2 through the assembly cylinder 642, and contacts the placement platform 4 and the sealing ring 5 when away from the chassis 2, and stops when it rises to a suitable height. At this time, the collecting fan 62 is driven by the motor to rotate, so that it drives the external air into the collection shell 61, and then enters the detector 63 inside the assembly cylinder 642 through the blocking plate 641 for inspection. As the detector 63 sends the detection data to the controller 7 for observation, the detected air flows to the inside of the sealing shell 651 through the filter screen 644 inside the inner partition shell 643, and the photocatalytic decomposition component 654 inside the sealing shell 651 processes the air. , and the inner support frame 652 fixes the photocatalytic decomposition element 654, and the deflector frame 653 moves inside the sealed shell 651 with the air flowing through the photocatalytic decomposition element 654, and the exhaust fan inside the exhaust duct 3 rotates to discharge the air inside the sealed shell 651, and after a period of detection, the hydraulic rod 67 extends again to repeat the above movement to collect and detect the air at different heights. After the detection is completed, the hydraulic rod 67 is extended and retracted to drive the collection shell 61 to descend to the inside of the chassis 2. As the collection shell 61 contacts the cleaning rod 663, the cleaning rod 663 slides on the clamping ring 664 when squeezed by the collection shell 61, and the cleaning rod 663 is used to clean the surface of the collection shell 61, and the clamping ring 664 and the limiting arc plate 662 support the fixed shell 661, and the fixed shell 661 is installed inside the chassis 2.

[0044] See also Figure 6-Figure 8On the basis of Example 1, the present invention provides a technical solution: the storage rack 645 includes a protective ring 73, a support shell 75 is fixedly connected to the bottom of the protective ring 73, a heating pipe 74 is fixedly connected to the inner surface of the support shell 75, and the outer surface of the protective ring 73 is connected to the load-bearing arc block 71. Heat can be generated by the heating pipe 74 inside the support shell 75, which is convenient for heat transfer when the support shell 75 is connected to the protective ring 73, so that the heat can keep the inside of the activated carbon placement box 72 dry, avoiding the influence of moisture on the adsorption efficiency of the activated carbon when the activated carbon is used, and the support shell 75 can increase the contact area of ​​the protective ring 73 when connected to the protective ring 73, so that the protective carbon can be placed in the storage rack 645. The protective ring 73 collects and processes the air circulating inside the inner partition shell 643. An activated carbon placement box 72 is fixedly connected to the bottom of the inner cavity of the supporting arc block 71. The side of the activated carbon placement box 72 away from the supporting arc block 71 passes through the protective ring 73 and extends to the inside of the protective ring 73. The activated carbon placed inside the activated carbon placement box 72 purifies the air circulating after detection through the protective ring 73, so that the activated carbon can cooperate with the photocatalytic decomposition element 654, thereby improving the air treatment quality. At the same time, the activated carbon placement box 72 can add activated carbon to the supporting arc block 71 through the opening and closing cover of the supporting arc block 71, so that the activated carbon can be replenished in time after consumption.

[0045] The contact ring 655 includes a contact-increasing ring 81, the bottom of the inner cavity of the contact-increasing ring 81 is fixedly connected with a middle solid ring 83, the top of the contact-increasing ring 81 is fixedly connected with an arc block 82, the top of the arc block 82 is fixedly connected to the contact-increasing ring 81, and the top of the contact-increasing ring 81 is located on both sides of the arc block 82 and is fixedly connected with clamping members 84, which are evenly distributed on the middle solid ring 83 through the clamping members 84, so that the clamping members 84 can fix the hydraulic rod 67 on the contact-increasing ring 81, so that multiple hydraulic rods 67 move together to push the contact-increasing ring 81, thereby avoiding the tilting of the contact-increasing ring 81 when it moves, thereby ensuring the stability of the movement of the contact-increasing ring 81, and the contact-increasing ring 81 is stable. When the clamping member 84 moves, there is a gap between the cleaning rod 663, thereby avoiding the problem of direct contact between the cleaning rod 663 and the contact-increasing ring 81. The bottom of the clamping member 84 penetrates the contact-increasing ring 81 and extends to the outside of the contact-increasing ring 81. The inner surface of the contact-increasing ring 81 is fixedly connected with an extrusion arc block 85. The arc blocks 82 are evenly distributed inside the contact-increasing ring 81 so that they contact with the middle solid ring 83 to reinforce the contact-increasing ring 81, thereby increasing the bearing capacity of the surface of the contact-increasing ring 81 and avoiding the problem of depression or fracture of the surface of the contact-increasing ring 81. The arc blocks 82 cooperate with the extrusion arc blocks 85, so that the sealing shell 651 can be fixed on the contact-increasing ring 81 by using the extrusion arc blocks 85.

[0046] The reinforcement frame 665 includes a mounting ring 93, a connecting frame 94 is fixedly connected to the top of the mounting ring 93, the bottom of the connecting frame 94 passes through the mounting ring 93, a docking ring 92 is fixedly connected to the outer surface of the mounting ring 93, and a fixing column 91 is fixedly connected to the top of the docking ring 92. The connecting frame 94 on the mounting ring 93 cooperates with the fixing column 91 on the docking ring 92, so that the fixed shell 661 can be fixed. The connection between the mounting ring 93 and the docking ring 92 facilitates the mutual support of the mounting ring 93 and the docking ring 92, thereby increasing the strength of the mounting ring 93 itself, and the mounting ring 93 and the docking ring 92 can be used to fix the fixed shell 661. The pressure on the shell 661 after installation is shared, so that it is not easy to loosen or fall off the fixed shell 661. The bottom end of the fixing column 91 passes through the docking ring 92 and extends to the inside of the docking ring 92. The bottom of the docking ring 92 is fixedly connected with a fixed arc plate 95, which is evenly distributed on the docking ring 92 through the fixed arc plate 95, so that the fixed arc plate 95 can support it on the chassis 2, thereby increasing the stability of the docking ring 92 itself while ensuring the stability of the cleaning process, thereby improving the convenience of the overall adjustment of the equipment, making it difficult for the equipment to be touched during use and adjustment, and further ensuring the overall integrity of the equipment.

[0047] When in use, the hydraulic rod 67 is installed inside the clamping piece 84 on the middle solid ring 83, so that the hydraulic rod 67 drives the contact increasing ring 81 to move through the clamping piece 84, and the contact increasing ring 81 contacts the sealing shell 651 through the extrusion arc block 85, and the arc block 82 on the middle solid ring 83 contacts the contact increasing ring 81. As the air enters the inner partition shell 643, the activated carbon inside the activated carbon placement box 72 adsorbs and purifies the air through the protective ring 73, and the heating tube 74 inside the supporting shell 75 transfers the heat to the activated carbon placement box 72 through the protective ring 73 to dry the activated carbon, and the opening and closing cover of the supporting arc block 71 can add activated carbon to the activated carbon placement box 72. The fixed arc plate 95 is connected to the chassis 2 on the docking ring 92, and the docking ring 92 is connected to the mounting ring 93, so that the fixed column 91 on the docking ring 92 and the connecting frame 94 on the mounting ring 93 contact and fix the fixed shell 661.

[0051] Step 3: After the air is collected, it enters the assembly cylinder 642 through the blocking plate 641 and contacts the detector 63 for detection. After being squeezed out, it enters the inner partition shell 643 and circulates through the filter screen 644. During the circulation process, the activated carbon in the activated carbon placement box 72 purifies the air inside the inner partition shell 643 through the protective ring 73, and at the same time, the photocatalytic decomposition element 654 processes the air under the support of the inner support frame 652;

[0052] Step 4: As the air is circulated after treatment, the baffle frame 653 on the photocatalytic decomposition element 654 is blown, so that the air inside the sealed shell 651 is discharged through the exhaust duct 3, and the fixed arc plate 95 supports the docking ring 92 inside the chassis 2, and the docking ring 92 cooperates with the mounting ring 93, so that the fixed column 91 and the connecting frame 94 reinforce the fixed shell 661;

[0053] Step 5: After the detection is completed, the hydraulic rod 67 drives the assembly cylinder 642 to descend, and the collection shell 61 is driven by the assembly cylinder 642 to enter the inside of the chassis 2, so that the collection shell 61 contacts and squeezes the cleaning rod 663, so that the cleaning rod 663 slides on the clamping ring 664;

[0054] Step six: As the cleaning rod 663 cleans the back of the collection shell 61, the cleaning rod 663 slides on the limiting arc plate 662 on the fixed shell 661, and there is a spring between the cleaning rod 663 and the limiting arc plate 662. When the cleaning rod 663 leaves the collection shell 61, the cleaning rod 663 automatically returns to the initial position.
