Description
Technical Field
[0001] This utility model relates to the field of air sampler technology, specifically an indoor air sampler. Background Technology
[0002] Indoor air pollution refers to the presence of substances in the air of enclosed spaces that are harmful to human health, with concentrations exceeding national standards and reaching levels that can harm human health. This phenomenon is collectively referred to as indoor air pollution. As people become increasingly aware of air quality and safety, they generally conduct necessary testing and treatment of the air in newly renovated homes to ensure their respiratory safety and meet their actual living needs. Therefore, indoor air sampling and testing are necessary to determine whether the indoor environment is clean.
[0003] Existing indoor air samplers often fail to clean residual substances from the previous air sample when they are used again. These residual substances can affect the quality of the next sample and the test results, thus reducing the overall quality of the sampler. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an indoor air sampler that solves the problem that when air samples need to be used a second time, it is often impossible to clean the substances remaining in the air after the previous sample, thus affecting the quality of the next sample collection and the test results, and reducing the overall quality of the sampler.

Through the arrangement of the cleaning mechanism, water pump, water tank, and connecting pipe, the inner wall of the collection tube can be flushed, thereby removing residual materials from the air collected previously, avoiding contamination of the air collected next time, and improving the collection quality of the collector.
[0011] Preferably, the rotating mechanism includes a power component, which is fixedly installed at the bottom of the fixed plate, and the output end of the power component passes through the bottom wall of the fixed plate and is fixedly connected to the bottom of the rotating plate.

[0015] (III) Beneficial Effects
[0016] This invention provides an indoor air sampler. It has the following beneficial effects:
[0017] (I) This indoor air sampler, through the setup of a cleaning mechanism, water pump, water tank, and connecting pipe, pumps water from the water tank to the inner wall of the sampling tube. Then, the motor is started to drive the L-shaped rod to rotate, which in turn drives the brush plate to rotate. The rotating brush plate and the pumped water can clean and rinse the inner wall of the sampling tube. Thus, through the setup of the cleaning mechanism, water pump, water tank, and connecting pipe, the inner wall of the sampling tube can be rinsed, thereby removing residual substances from the previously collected air, avoiding contamination of the next air sample, and improving the sampling quality of the sampler.
[0018] (II) This indoor air sampler, through the setting of an electric telescopic rod and a rotating mechanism, allows the sampler to collect air at different heights indoors by adjusting the height of the sampler via the electric telescopic rod. This reduces the error in air quality between different heights and improves the sampling accuracy. The starting power component drives the rotating plate to rotate, and the ball bearings on the bottom side of the rotating plate slide in the slide groove. At the same time, the limiting block slides in the limiting groove, preventing the rotating plate from detaching from the fixed plate. Thus, the rotation of the rotating plate can change the orientation of the air inlet pipe, thereby enabling the sampler to collect air at different positions at the same height and improving the sampling accuracy.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0027] See Figure 1-6This utility model provides a technical solution: an indoor air sampler, the structure of which includes a base 1, a pulley 2 fixedly installed at the bottom of the base 1, an electric telescopic rod 3 fixedly connected to the top of the base 1, a fixed plate 4 fixedly connected to the top of the electric telescopic rod 3, a rotating plate 5 provided on the top side of the fixed plate 4, a water tank 6 fixedly connected to one side of the top of the rotating plate 5, a transition cylinder 7 fixedly connected to the other side of the top of the rotating plate 5, a collection cylinder 8 fixedly connected to the top of the transition cylinder 7, a cleaning mechanism 9 provided inside the collection cylinder 8, a connecting pipe 10 connected to the top of the water tank 6, one end of the connecting pipe 10 fixedly connected to one side of the top of the collection cylinder 8, a water pump 15 fixedly connected to the surface of the connecting pipe 10, an air inlet pipe 11 connected to one side of the transition cylinder 7, a rotating mechanism 12 jointly provided between the fixed plate 4 and the rotating plate 5, and an air pump 18 fixedly installed inside the air inlet pipe 11. When the air inlet valve 14 is opened, the air pump 18 is started to draw indoor air from the inlet pipe. The air is drawn into the transition tube 7 through the air tube 11 and then into the collection tube 8, thus enabling the collection of indoor air. Before collection, the height of the collector can be adjusted by controlling the electric telescopic rod 3, allowing the collector to collect air at different heights in the room, reducing the error in air quality between different heights and improving the collection accuracy. Furthermore, the position of the air inlet tube 11 can be adjusted by rotating the rotating mechanism 12, allowing the collection of air at different positions at the same height, further improving the collection accuracy of the collector, and the adjustment is convenient and quick. After collection, when it is necessary to collect indoor air again, the water in the water tank 6 is pumped into the collection tube 8 through the connecting pipe 10 by the water pump 15, and then the inner wall of the collection tube 8 is cleaned by the cleaning mechanism 9, thereby cleaning the impurities and other residues left on the inner wall of the collection tube 8 from the previous collection, avoiding the impact of residues on the secondary collection.
[0028] One end of the air intake pipe 11 is threadedly connected to a filter pipe 13, and an air intake valve 14 is fixedly connected to the surface of the air intake pipe 11. The filter pipe 13 can filter out large particulate impurities in the air to prevent them from damaging the collector.
[0029] Among them, the bottom back of the transition cylinder 7 is connected to a drain pipe 16, and a drain valve 17 is fixedly connected to the surface of the drain pipe 16.
[0030] The cleaning mechanism 9 includes a motor 91, which is fixedly installed on the top of the collection cylinder 8. The output end of the motor 91 passes through the top wall of the collection cylinder 8 and is fixedly connected to an L-shaped rod 92. A brush plate 93 is fixedly connected to one side of the L-shaped rod 92, and one side of the brush plate 93 abuts against the inner wall of the collection cylinder 8. The water pump 15 pumps water from the water tank 6 to the inner wall of the collection cylinder 8, and then starts the motor 91 to drive the L-shaped rod 92 to rotate. The L-shaped rod 92 drives the brush plate 93 to rotate. The rotating brush plate 93 and the pumped water can clean and rinse the inner wall of the collection cylinder 8. Thus, through the arrangement of the cleaning mechanism 9, the water pump 15, the water tank 6 and the connecting pipe 10, the inner wall of the collection cylinder 8 can be rinsed.
[0031] The rotating mechanism 12 includes a power component 121, which is fixedly installed on the bottom of the fixed plate 4. The output end of the power component 121 passes through the bottom wall of the fixed plate 4 and is fixedly connected to the bottom of the rotating plate 5.
[0032] The top of the fixing plate 4 is provided with a sliding groove 122 and a limiting groove 123, which is located outside the sliding groove 122.
[0033] The rotating plate 5 has multiple balls 124 embedded in its bottom side. The balls 124 are tactilely connected to the inside of the slide groove 122. Limiting blocks 125 are fixedly connected to both sides of the bottom of the rotating plate 5. The limiting blocks 125 are slidably connected to the inside of the limiting groove 123. The starting power component 121 drives the rotating plate 5 to rotate. The balls 124 on the bottom side of the rotating plate 5 slide in the slide groove 122, while the limiting blocks 125 slide in the limiting groove 123. This prevents the rotating plate 5 from detaching from the fixed plate 4. Thus, the rotation of the rotating plate 5 can change the orientation of the air intake pipe 11, thereby enabling the collection of air from different positions at the same height and improving the collection accuracy of the collector.
[0034] The height of the electric telescopic rod 3 when it is retracted is greater than the height of the power component 121, so as to prevent the power component 121 from touching the base 1.
[0035] When sampling indoor air using this sampler, the air inlet valve 14 is opened, and the air pump 18 is started to draw indoor air from the air inlet pipe 11 into the interior of the transition cylinder 7. Then, the air enters the collection cylinder 8 through the transition cylinder 7, thus enabling the collection of indoor air. Before collection, the height of the sampler can be adjusted by controlling the electric telescopic rod 3, so that the sampler can collect air at different heights in the room, reducing the error in air quality between different heights and improving the collection accuracy. Furthermore, the position of the air inlet pipe 11 can be adjusted by rotating the rotating mechanism 12, so that air at different positions at the same height can be collected, further improving the collection accuracy of the sampler. The adjustment is also convenient and quick. After collection, when it is necessary to collect indoor air again, the water pump 15 draws water from the water tank 6 into the interior of the collection cylinder 8 through the connecting pipe 10. Then, the cleaning mechanism 9 cleans the inner wall of the collection cylinder 8, thereby cleaning the impurities and other residues left on the inner wall of the collection cylinder 8 from the previous collection, avoiding the influence of residues on the secondary collection.
[0036] When cleaning the inner wall of the collection cylinder 8 through the cleaning mechanism 9, the water pump 15 is first started to work. The water pump 15 draws water from the water tank 6 to the inner wall of the collection cylinder 8. Then, the motor 91 is started to drive the L-shaped rod 92 to rotate. The L-shaped rod 92 drives the brush plate 93 to rotate. The rotating brush plate 93 and the pumped water can clean and rinse the inner wall of the collection cylinder 8. Thus, through the arrangement of the cleaning mechanism 9, the water pump 15, the water tank 6 and the connecting pipe 10, the inner wall of the collection cylinder 8 can be rinsed, thereby removing the residual materials in the air collected last time, avoiding contamination of the air collected next time, and improving the collection quality of the collector.
[0037] When the rotating mechanism 12 is in operation, the power component 121 is first started to drive the rotating plate 5 to rotate. The ball bearings 124 on the bottom side of the rotating plate 5 slide in the slide groove 122, while the limiting block 125 slides in the limiting groove 123, which prevents the rotating plate 5 from detaching from the fixed plate 4. Thus, the rotation of the rotating plate 5 can change the orientation of the air intake pipe 11, thereby enabling the collection of air at different positions at the same height and improving the collection accuracy of the collector.
