Description

Technical Field

[0001] This utility model relates to the field of air sampler technology, specifically a mobile ambient air sampler. Background Technology

[0002] Currently, commonly used air sampling equipment is mainly divided into two categories: fixed and portable. While fixed sampling equipment can achieve long-term stable sampling, its fixed installation location makes it difficult to meet the dynamic monitoring needs of multiple areas and locations. Furthermore, the equipment is relatively large, requiring hoisting or transport vehicles for relocation, which is cumbersome and costly. Portable sampling equipment, although possessing some mobility, often sacrifices structural stability in pursuit of portability. When sampling in complex outdoor terrain, it is prone to displacement due to minor collisions, affecting sampling accuracy. Additionally, the storage and switching of most portable devices require disassembling or folding multiple parts, a complex process that not only prolongs preparation time but may also cause wear and tear on components due to repeated disassembly and assembly, reducing the equipment's lifespan.

[0021] 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.

[0022] Please see Figure 1-7 This utility model provides the following technical solutions:

[0023] A mobile ambient air sampler includes an outer casing 1, an inner casing 6, and an air sampler body 7. The inner casing 6 is slidably disposed inside the outer casing 1, and its top is snap-fitted to the top of the outer casing 1. The air sampler body 7 is slidably disposed inside the inner casing 6. A telescopic handle 3 is provided on one side of the outer casing 1, and a top cover 2 is connected to the top of the outer casing 1 via a pivot pin. A buckle is provided on the side of the top cover 2 near the telescopic handle 3. A top handle 8 is provided on the top of the air sampler body 7, and a connecting base 20 is provided at the bottom of the air sampler body 7. The air sampler body 7 can be snapped onto the top of the inner casing 6 via the connecting base 20. A support frame 4 is provided at the bottom of the outer casing 1, and a bottom groove 9 is formed on the bottom surface of the outer casing 1. A base platform 10 is provided at the bottom of the inner casing 6, and casters 5 are provided at the bottom of the base platform 10, passing through the bottom groove. 9 extends to the outside of the outer casing 1. When the top cover 2 is closed and locked on the top of the outer casing 1, the top cover 2 abuts against the top handle 8. The outer casing 1, inner casing 6 and air sampler body 7 are tightly fitted together. The bottom of the support frame 4 is higher than the moving wheels 5. At this time, the entire device can be moved by the moving wheels 5. The support frame 4 will not touch the ground. When in use, pull the telescopic handle 3 to move the entire device to the area where it needs to work. Then, retract the telescopic handle 3 and open the top cover 2. Hold the top handle 8 and lift the air sampler body 7 upward. During the lifting process, the air sampler body 7 is connected to the top of the inner casing 6 through the connecting base 20. The top of the inner casing 6 is connected to the top of the outer casing 1, thereby raising the entire air sampler body 7 for air sampling. At this time, the moving wheels 5 are raised and the support frame 4 supports the entire device.

[0024] A spring groove 11 is provided on the inner top of the outer casing 1. The spring groove 11 is slidably disposed on the snap-fit ​​block 13. A snap-fit ​​spring 12 is provided between the spring groove 11 and the snap-fit ​​block 13. The two sides of the connecting base 20 are provided with spring grooves 11, snap-fit ​​springs 12 and snap-fit ​​blocks 13 with the same connection structure. The outer bottom and inner top of the inner casing 6 are provided with snap-fit ​​grooves that match the snap-fit ​​blocks 13. The snap-fit ​​blocks 13 are acted upon by the snap-fit ​​springs 12. When the snap-fit ​​grooves move to the same level as the snap-fit ​​blocks 13, they snap into the interior of the snap-fit ​​grooves. Thus, the outer casing 1, the inner casing 6 and the connecting base 20 are snapped together by the snap-fit ​​blocks 13, so that the air sampler body 7 can be taken out and raised as a whole.

[0025] A first inclined push block 14 is provided below the slot on the outer side of the bottom of the inner box 6. A first guide post 15 is provided inside the inner box 6. The first inclined push block 14 is slidably connected to the first guide post 15. A first push groove 18 is provided above the slot on the outer side of the bottom of the inner box 6. The size of the first push groove 18 is smaller than that of the snap-fit ​​block 13. A first push block 17 is provided inside the first push groove 18. The first push block 17 and the first inclined push block 14 are connected by a connecting plate 16. The inclined surface of the first inclined push block 14 faces the slot on the outer side of the bottom of the inner box 6. When it is necessary to cancel the snap-fit ​​state between the inner box 6 and the outer box 1, the first push block 17 is pushed upward. At this time, the first push block 17 drives the first inclined push block 14 to move upward along the direction of the first guide post 15 through the connecting plate 16. At this time, the first inclined push block 14 lifts the snap-fit ​​block 13 through the inclined surface and pushes it back into the spring groove 11. At this time, the snap-fit ​​state between the inner box 6 and the outer box 1 is successfully released, and the inner box 6 can be folded down and stored back into the outer box 1.

[0026] A second inclined push block 19 is provided above the slot on the inner side of the top of the inner box 6. A second guide post 22 is provided inside the inner box 6. The second inclined push block 19 is slidably connected to the second guide post 22. A second push groove 23 is provided on the other side of the second guide post 22. The size of the second push groove 23 is smaller than that of the snap-fit ​​block 13. A second push block 21 is provided inside the second push groove 23. The second push block 21 is connected to the second inclined push block 19. The inclined surface of the second inclined push block 19 faces the slot on the inner side of the top of the inner box 6. When it is necessary to cancel the snap-fit ​​state between the inner box 6 and the connecting base 20, the second push block 21 is pushed down. At this time, the second push block 21 drives the second inclined push block 19 to move upward along the direction of the second guide post 22. At this time, the second inclined push block 19 lifts the snap-fit ​​block 13 through the inclined surface and pushes it back into the spring groove 11. At this time, the snap-fit ​​state between the inner box 6 and the connecting base 20 is successfully released, and the air sampler body 7 can be retracted into the inner box 6.

[0027] Specifically, the device uses casters and a telescopic handle. When not in operation, the bottom of the support frame is higher than the casters, allowing the device to be easily pushed or pulled, facilitating transfer between different sampling areas and reducing the burden of manual handling. When in operation, the air sampler body is raised, the casters rise, and the support frame contacts the ground to support the device. The stability of the support frame replaces the casters, preventing the device from sliding due to accidental contact during sampling and ensuring the stability of the sampling work.

[0028] With the help of snap-fit ​​blocks, snap-fit ​​springs, and snap-fit ​​slots, the outer casing, inner casing, and air sampler body (via the connecting base) can be quickly snapped together and fixed. Simply lift the air sampler body, and the multi-layer snap-fit ​​structure will raise it to the working position, eliminating the need for complicated assembly steps. To release the snap-fit ​​state, push the first or second push block, and use the inclined surface of the push block to lift the snap-fit ​​block, which can quickly release the fixation between the components and store the inner casing and sampler body back into the outer casing. The operation is simple and efficient, saving time on state switching.

[0029] The telescopic handle is ergonomically designed for easy pulling of the device; the top handle makes it easy to lift the sampler body, requiring minimal physical effort during operation. The size design of the push block and push slot (the push slot is smaller than the snap-fit ​​block) prevents the snap-fit ​​block from accidentally getting stuck in the push slot, ensuring structural reliability. The device integrates mobility, storage, support, and sampling into one unit, eliminating the need for additional moving tools or support devices, reducing the complexity of carrying the equipment, and making it particularly suitable for outdoor, multi-location air sampling work.

[0030] It should be noted that this utility model does not involve technical improvements on how to sample air. This utility model improves the mobility of existing air sampling equipment. For existing technologies on how to sample air, please refer to the air sampling equipment currently available on the market.
