Description

Technical Field

[0001] This utility model relates to the field of air detection technology, and in particular to an easy-to-use air collection device for air detection. Background Technology

[0002] Air quality is one of the important factors affecting people's health. Before conducting air testing, air needs to be collected. Currently, there are many different types of air collection devices for air testing on the market, but most of them are inconvenient to use and costly.

[0003] Existing technology, such as Chinese Patent Publication No. CN207263499U, discloses an easy-to-use air collection device for air detection, including a housing, elastic rope, water pipe, and shoulder strap. An air collection bottle is fixed inside the housing, and a card slot is provided at the front of the air collection bottle. The elastic rope is fixed to the rear of the air collection bottle, and a rubber stopper is provided at the top of the air collection bottle. An air tube passes through the middle of the rubber stopper and has a first valve. The water tube is located at the bottom of the air collection bottle and has a second valve. The end of the water tube is connected to a water tank, and a water outlet is provided at the bottom of the water tank. A cover is provided at the water outlet, and the bottom of the cover has a wear-resistant layer. The shoulder strap is fixed to the side of the housing. This easy-to-use air collection device for air detection has four air collection bottles of equal size, which can collect air from different areas for comparison during air detection. However, the amount of air collected in a single operation is fixed and cannot be adjusted according to the needs of subsequent tests.

[0004] To address the issue that air collection devices for air testing are not convenient for adjusting the amount of air collected per batch according to actual needs, existing equipment often collects a fixed amount of air per batch. However, subsequent testing may require comparison of different amounts of air. If multiple samples are taken using different collection containers, it is time-consuming and labor-intensive. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing air collection devices for air detection are not convenient to adjust the amount of air collected at one time according to actual needs, and to propose an easy-to-use air collection device for air detection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an easy-to-use air collection device for air detection, comprising a housing, rollers, a collection bottle, and a collection mechanism. The rollers are disposed on the bottom surface of the housing, the collection bottle is disposed inside the housing, and the collection mechanism is disposed on the surface of the collection bottle. The collection mechanism includes a collection component, an adjustment component, and an auxiliary component. The collection component includes a water pipe that is connected to the top surface of the collection bottle. An air pipe is connected to the surface of the collection bottle, and a valve is disposed on the surface of the air pipe. A sealing plate is slidably connected to the inner wall of the collection bottle, and a movable rod is fixedly connected to the surface of the sealing plate. The movable rod is slidably connected to the inner wall of the collection bottle, and a pull plate is fixedly connected to the surface of the movable rod. The adjustment component includes an adjustment hole that is opened on the surface of the movable rod. A positioning rod is slidably connected to the inner wall of the collection bottle, and the positioning rod is inserted into the surface of the adjustment hole.

[0007] Furthermore, a pull plate is fixedly connected to the surface of the positioning rod, and a spring is sleeved and connected to the surface of the positioning rod. One end of the spring is fixedly connected to the surface of the pull plate, and the other end of the spring is fixedly connected to the surface of the collection bottle.

[0008] Furthermore, there are multiple collection bottles, two sets of movable rods, multiple and evenly distributed adjustment holes, two sets of positioning rods, and the air tube penetrates the surface of the box.

[0009] Furthermore, the auxiliary component includes a scale groove, which is formed on the surface of the movable rod. There are multiple scale grooves, and the scale grooves cooperate with the adjustment holes.

[0010] Furthermore, a water tank is fixedly connected to the surface of the box, and the water tank is matched with a water pipe.

[0011] Furthermore, the surface of the box is fixedly connected with straps, the surface of the straps is fixedly connected with Velcro closure one, and the surface of the box is fixedly connected with Velcro closure two.

[0012] Furthermore, the first and second hook and loop fasteners are adhesively connected, and the straps cooperate with the water pipe.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a collection mechanism, opening the valve, holding the pull plate and pulling the positioning rod, while tightening the spring, the positioning rod disengages from the adjustment hole. Water is then poured into the collection bottle through the water pipe. Under the weight of the water, the sealing plate moves downwards, completely expelling air from the collection bottle through the air pipe. The valve is then closed, and the box is moved to the sampling area using rollers. The valve is then opened again, and the pull plate is pulled to disengage the positioning rod from the adjustment hole. Simultaneously, the pull plate is pulled, causing the movable rod to move the sealing plate upwards. Water is drained through the water pipe, and negative pressure is used to draw air into the collection bottle through the air pipe. The valve is then closed, and the box is moved to the next area for sampling. During this process, the remaining water inside the bottle and water pipe can play an auxiliary sealing role. Finally, connect the gas pipe to the detection device, pull the pull plate and press down the pull plate to discharge the gas into the detection device for testing. The air sampling volume can be adjusted as needed. Simply observe the scale groove when sampling, pull the sealing plate to a certain position and then release the pull plate. Under the action of spring rebound, the positioning rod will be inserted into the corresponding adjustment hole. The water tank can properly collect the water flowing out of the water pipe. The straps, together with Velcro 1 and Velcro 2, can properly fix the water pipe to avoid damage to the water pipe or turbulence of the water inside the pipe due to random placement.

[0015] 2. In this utility model, by setting up a collection mechanism, air samples from different areas can be conveniently taken separately, and the amount of air collected at one time can be adjusted as needed while ensuring airtightness, which facilitates subsequent quantitative detection and comparison reference, thus effectively improving the convenience of the equipment.

[0023] Please see Figures 1-5 This utility model provides a technical solution: an easy-to-use air collection device for air detection, including a housing 1, rollers 2, a collection bottle 3 and a collection mechanism 4. The rollers 2 are disposed on the bottom surface of the housing 1, the collection bottle 3 is disposed inside the housing 1, and the collection mechanism 4 is disposed on the surface of the collection bottle 3.

[0024] The following section will explain the specific setup and function of its collection mechanism 4.

[0025] In this embodiment: the collection mechanism 4 includes a collection component 41, an adjustment component 42, and an auxiliary component 43. The collection component 41 includes a water pipe 411, which is connected to the top surface of the collection bottle 3. An air pipe 412 is connected to the surface of the collection bottle 3. A valve 413 is provided on the surface of the air pipe 412. A sealing plate 414 is slidably connected to the inner wall of the collection bottle 3. A movable rod 415 is fixedly connected to the surface of the sealing plate 414. The movable rod 415 is slidably connected to the inner wall of the collection bottle 3. A pull plate 416 is fixedly connected to the surface of the movable rod 415. The adjustment component 42 includes an adjustment hole 421, which is opened on the surface of the movable rod 415. A positioning rod 422 is slidably connected to the inner wall of the collection bottle 3. The positioning rod 422 is inserted into the surface of the adjustment hole 421.

[0026] The effects achieved by the above components are as follows: the water pipe 411 is provided to facilitate the input of clean water into the collection bottle 3, which facilitates the expulsion of air from the collection bottle 3 to create a negative pressure environment, and can also increase the sealing of the collection bottle 3 in conjunction with the sealing plate 414 after collection is completed; the air pipe 412 is provided to facilitate the intake and exhaust of air; the valve 413 is provided to facilitate the closure of the air pipe 412; the sealing plate 414 is provided to facilitate the division of the collection bottle 3 into upper and lower areas that do not interfere with each other; the movable rod 415 and the pull plate 416 are provided to facilitate the movement of the sealing plate 414; and the adjustment hole 421 and the positioning rod 422 are provided to facilitate the fixation of the sealing plate 414.

[0027] Specifically, a pull plate 423 is fixedly connected to the surface of the positioning rod 422, and a spring 424 is sleeved and connected to the surface of the positioning rod 422. One end of the spring 424 is fixedly connected to the surface of the pull plate 423, and the other end of the spring 424 is fixedly connected to the surface of the collection bottle 3.

[0028] The effects achieved by the above components are as follows: the pull plate 423 is set to facilitate pulling the positioning rod 422, and the spring 424 is set to both lock the positioning rod 422 into the adjustment hole 421 and facilitate the reset of the positioning rod 422 by utilizing its rebound effect.

[0029] Specifically, there are multiple collection bottles 3, two sets of movable rods 415, multiple and evenly distributed adjustment holes 421, two sets of positioning rods 422, and air pipes 412 penetrating the surface of the box 1.

[0030] The effects achieved by the above components are as follows: setting multiple collection bottles 3 is for sampling air from different areas; setting two sets of movable rods 415 is for increasing the stability of the movement of the sealing plate 414; setting multiple adjustment holes 421 is for fixing the sealing plate 414 at different positions to facilitate adjustment of the amount of air collected inside; and setting two sets of positioning rods 422 is to avoid the situation of easy accidental contact caused by setting only one set of positioning rods 422.

[0031] Specifically, the auxiliary component 43 includes a scale groove 431, which is formed on the surface of the movable rod 415. There are multiple scale grooves 431, and the scale grooves 431 cooperate with the adjustment hole 421.

[0032] The effect achieved by the above components is as follows: the scale groove 431 is set for easy observation, so that the positioning rod 422 can be inserted into the adjustment hole 421 at the appropriate position, thereby realizing the adjustment of the amount of air collected in the collection bottle 3.

[0033] Specifically, a water tank 432 is fixedly connected to the surface of the box 1, and the water tank 432 is matched with the water pipe 411.

[0034] The effect achieved by the above components is that the water tank 432 is set up to facilitate the collection of water discharged from the water pipe 411 and prevent water from flowing to other places.

[0035] Specifically, the surface of the box 1 is fixedly connected with a strap 433, the surface of the strap 433 is fixedly connected with a Velcro 434, and the surface of the box 1 is fixedly connected with a Velcro 435.

[0036] The effect achieved by the above components is as follows: the straps 433, Velcro 434 and Velcro 435 are provided to facilitate proper fixation of the water pipe 411, and to prevent the water pipe 411 from being damaged due to random placement or the water inside the pipe from flowing out of the water tank 432.

[0037] Specifically, Velcro 1 434 and Velcro 2 435 are adhesively connected, and cable tie 433 is used in conjunction with water pipe 411.

[0038] The effect achieved by the above components is that the adhesive connection of Velcro 434 and Velcro 435 can not only provide a proper fixing effect, but also facilitate quick release of the fixing of the water pipe 411.

[0039] Working principle: By setting up the collection mechanism 4, opening the valve 413, holding the pull plate 423 and pulling the positioning rod 422, while tightening the spring 424, the positioning rod 422 is disengaged from the adjustment hole 421. Water is then poured into the collection bottle 3 through the water pipe 411. Under the weight of the water, the sealing plate 414 is moved downwards, completely expelling the air from the collection bottle 3 through the air pipe 412. Then, the valve 413 is closed, and the roller 2 is used to move the box 1 to the sampling area. The valve 413 is then opened again, and the pull plate 423 is pulled again to disengage the positioning rod 422 from the adjustment hole 421. Simultaneously, the pull plate 416 is pulled, causing the movable rod 415 to move the sealing plate 414 upwards. While draining water through the water pipe 411, negative pressure is used to draw air into the collection bottle 3 through the air pipe 412. Finally, the valve 413 is closed, and the box 1 is moved to the lower... Sampling is performed in one area. During this period, the remaining water in bottle 3 and water pipe 411 can play an auxiliary sealing role. Finally, the gas pipe 412 is connected to the detection device. Pulling the pull plate 423 and pressing down the pull plate 416 will allow the gas to be discharged into the detection device for detection. The amount of air sampled can be adjusted as needed. Simply observe the scale groove 431 during sampling, pull the sealing plate 414 to a certain position, and then release the pull plate 423. Under the rebound action of the spring 424, the positioning rod 422 will be inserted into the corresponding adjustment hole 421. The water tank 432 can properly collect the water flowing out of the water pipe 411. The strap 433, together with Velcro 1 434 and Velcro 2 435, can properly fix the water pipe 411 to avoid damage to the water pipe 411 or turbulence of the water inside the pipe due to random placement.

[0040] By setting up the collection mechanism 4, air samples can be easily taken from different areas. Furthermore, the amount of air collected at one time can be adjusted as needed while ensuring airtightness, which facilitates subsequent quantitative testing and comparison. This effectively improves the convenience of the equipment.
