Description

Technical Field

[0001] This utility model belongs to the field of data collection device technology, specifically relating to a sampling and collection device for a fresh air introduction system for human living environments. Background Technology

[0002] Sampling and collection devices in residential fresh air introduction systems are generally used to collect air samples from the fresh air system in order to detect and analyze air quality.

[0003] Chinese patent CN211825278U discloses a sampling and collection device for a fresh air introduction system in a residential environment, including a connecting seat; a sampling cylinder is rotatably connected to the connecting seat. When the sampling cylinder is threadedly tightened to the connecting seat, the locking plate contacts the cylindrical rod, and under the push of the cylindrical rod, the locking plate disengages from the bottom surface of the inner wall of the sampling cylinder, at which point the air inlet is open. When it is necessary to transfer the gas in the sampling cylinder to the detection position, the sampling cylinder is removed from the connecting seat. At this time, the elastic element elastically extends, the locking plate contacts the bottom surface of the inner wall of the sampling cylinder, and the air inlet is sealed, thus preventing gas leakage when the sampling cylinder is transferred.

[0004] The above-mentioned device adopts a technical means that the sampling tube is in a sealed state when it is removed. However, when using the above-mentioned device, it may be contaminated due to its own materials or external factors during the sampling and collection process, which may affect the accuracy of the sample. The existing sampling and collection device does not have a filtration structure. Therefore, a new sampling and collection device for a fresh air introduction system in the living environment is needed to improve the above-mentioned device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sampling and collection device for a fresh air introduction system for residential environments, which has the advantage of automatic filtration and solves the problem of filtering the collected air.

[0006] To achieve the above-mentioned purpose of filtering the air collected by the sampling and collection device, the present invention provides the following technical solution: a sampling and collection device for a fresh air introduction system for a residential environment, including an air inlet pipe, a sampling cylinder threadedly connected to the air inlet pipe, and a filter assembly installed at the connection between the air inlet pipe and the sampling cylinder, and a recycling assembly detachably connected to the outer wall of the filter assembly.

[0007] The filter assembly includes a housing that is threaded to the air inlet pipe and the sampling cylinder at both ends, respectively. A filter screen is detachably connected to the middle of the inner wall of the housing, and drain ports are symmetrically cut on the housing on both sides of the filter screen.

[0008] The recycling assembly includes an upper clamp and a lower clamp that fit over the outer shell. Connecting blocks are symmetrically fixed to both sides of the upper and lower clamps. Threaded holes are drilled in the connecting blocks, and bolts are threaded into the threaded holes. An arc-shaped opening is provided at the bottom of the lower clamp, and a recycling bag is detachably connected to the surface of the lower clamp located directly below the arc-shaped opening.

[0009] Furthermore, the recycling bag is symmetrically fixed with hanging ropes at both ends, and the hanging ropes are engaged with bolts.

[0010] Furthermore, protective covers are symmetrically fitted onto the surfaces of the filter assembly and the recycling assembly, and locking blocks are symmetrically fixedly connected to the cross-sections on both sides of the protective covers.

[0011] Furthermore, each of the card blocks has a magnetic block fixedly connected to one end of each other, and the corresponding two magnetic blocks attract each other.

[0012] Furthermore, an annular magnetic plate is fixedly connected to the inner wall of the outer shell, a magnetic sheet is fitted around the outer ring of the filter screen, and the lower clamp is fixed by attraction between the magnetic sheet and the annular magnetic plate.

[0013] Furthermore, the recycling bags are made of biodegradable plastic.

[0014] Furthermore, the filter screen is made of fine stainless steel.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In use, this utility model, by setting up a filter component and a recovery component, allows for sampling and testing of the fresh air introduction system using a sampling device. The two ends of the outer shell can be threadedly fixed to the air inlet pipe and sampling cylinder respectively. Then, the upper and lower clamps are fitted onto the surface of the outer shell and fixed with bolts and threaded holes. At this point, the arc-shaped opening corresponds to the drain outlet. When collecting air, impurities in the air are filtered out as it passes through the filter screen. Impurities adhering to the filter screen fall into the drain outlet and then into the recovery bag for collection, facilitating later processing. This effectively achieves the effect of automatic air filtration during sampling of the fresh air introduction system.

[0017] 2. When using this utility model, by setting up protective covers, before sampling, the recycling bag can be hung on the bolts on both sides by hanging ropes, and then pressed between the bag and the connecting block by the bolts for reinforcement. At this time, the recycling bag covers the entire lower clamp inside, which facilitates the collection of impurities. After the collection is completed, the two protective covers can be put on the surface of the upper clamp and fixed by magnetic attraction, thereby covering the filter component and the recycling component inside, preventing dust from entering and causing pollution.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a sampling and collection device for a fresh air introduction system for human living environment, including an air inlet pipe 1, a sampling cylinder 2 threadedly connected to the air inlet pipe 1, and a filter assembly 3 installed at the connection between the air inlet pipe 1 and the sampling cylinder 2, and a recycling assembly 4 detachably connected to the outer wall of the filter assembly 3.

[0026] The filter assembly 3 includes a housing 301 with its two ends threadedly connected to the air inlet pipe 1 and the sampling cylinder 2 respectively. A filter screen 302 is detachably connected to the middle of the inner wall of the housing 301. Drainage ports 303 are symmetrically cut on the housing 301 located on both sides of the filter screen 302.

[0027] The recycling component 4 includes an upper clamp 401 and a lower clamp 402 fitted onto the surface of the outer casing 301. Connecting blocks 408 are symmetrically fixed to both sides of the upper clamp 401 and the lower clamp 402. Threaded holes 407 are drilled in the connecting blocks 408, and bolts 406 are threaded into the threaded holes 407. An arc-shaped opening 404 is formed at the bottom of the lower clamp 402. A recycling bag 405, made of biodegradable plastic, is detachably connected to the surface of the lower clamp 402 directly below the arc-shaped opening 404. The filter screen 302 is made of fine stainless steel.

[0028] By setting up the filter assembly 3 and the recovery assembly 4, when using the sampling device to sample and test the fresh air introduction system, the two ends of the outer shell 301 can be threaded to the air inlet pipe 1 and the sampling cylinder 2 respectively. Then, the upper clamp 401 and the lower clamp 402 are put on the surface of the outer shell 301 and fixed with the bolt 406 and the screw hole 407. At this time, the arc-shaped opening 404 corresponds to the position of the drain outlet 303. When collecting air, when passing through the filter screen 302, the impurities in the air are filtered down, and the impurities stuck on the filter screen 302 will fall into the drain outlet 303 and then fall from the arc-shaped opening 404 into the recovery bag 405 for collection, which is convenient for later processing. This effectively achieves the effect of automatic air filtration when sampling the fresh air introduction system.

[0029] like Figure 1 and Figure 3-4 The recycling bag 405 is symmetrically fixed with hanging ropes 403 at both ends, and the hanging ropes 403 are engaged with bolts 406. The filter assembly 3 and the recycling assembly 4 are symmetrically fitted with protective covers 5. The protective covers 5 are symmetrically fixed with locking blocks 7 at both sides of the cross section. The locking blocks 7 are fixedly connected with magnetic blocks 6 at one end close to each other, and the corresponding two magnetic blocks 6 attract each other. The inner wall of the outer shell 301 is fixedly connected with an annular magnetic plate 304. The filter screen 302 is fitted with a magnetic sheet 305 on the outer ring, and the lower clamp 402 is fixed by attraction between the magnetic sheet 305 and the annular magnetic plate 304.

[0030] By setting up the protective cover 5, before sampling, the recycling bag 405 can be hung on the bolts 406 on both sides by the hanging rope 403, and then pressed between the bag and the connecting block 408 by the bolts 406 for reinforcement. At this time, the recycling bag 405 covers the entire lower clamp 402 inside, which facilitates the collection of impurities. After the collection is completed, the two protective covers 5 can be put on the surface of the upper clamp 401 and fixed by magnetic blocks 6, thereby covering the filter component 3 and the recycling component 4 inside, preventing dust from entering and causing pollution.

[0031] The working principle of the above embodiment is as follows: Compared with the prior art, when using the sampling device to sample and detect the fresh air introduction system, the two ends of the outer shell 301 can be threaded to the air inlet pipe 1 and the sampling cylinder 2 respectively. Then, the upper clamp 401 and the lower clamp 402 are fitted onto the surface of the outer shell 301 and threaded to the screw hole 407 by bolts 406. At this time, the arc-shaped opening 404 corresponds to the position of the drain outlet 303. When collecting air, when passing through the filter screen 302, the impurities in the air are filtered down, and the impurities stuck on the filter screen 302 will fall into the drain outlet 303 and then fall from the arc-shaped opening 404 into the collection bag 405 for collection, which is convenient for later processing and effectively achieves the goal of... The fresh air intake system can automatically filter the air during sampling. Before sampling, the collection bag 405 can be hung on the bolts 406 on both sides by the hanging rope 403, and then pressed between the bag and the connecting block 408 by the bolts 406 for reinforcement. At this time, the collection bag 405 covers the entire lower clamp 402, which facilitates the collection of impurities. After the collection is completed, the two protective covers 5 can be put on the surface of the upper clamp 401 and fixed by magnetic blocks 6, thereby covering the filter component 3 and the collection component 4 inside, preventing dust from entering and causing pollution. This improves the practicality of the sampling and collection device and solves the problem that the sampling and collection device in the prior art does not have an air filtration structure.

[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
