Description

Technical Field

[0001] This utility model belongs to the field of environmental sample collection technology, specifically referring to a portable indoor environmental monitoring and sampling device. Background Technology

[0002] Portable indoor environmental monitoring sampling refers to the use of portable equipment and tools to collect samples of various pollutants or related indicators in the indoor environment.

[0003] A common method for indoor air sampling is through adsorption tubes. The sampling principle involves adding activated carbon to the adsorption tube, connecting it to a sampler, allowing it to enter the tube at a certain flow rate, then sealing and labeling it. However, existing adsorption tube technology has some drawbacks: after sampling, the tube is difficult to remove from the sampler, making it difficult to replace with a new tube; the sampling height is fixed, making it difficult to adjust the air sampling height. Therefore, improvements are needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that, in the prior art, it is inconvenient to adjust the collection height and replace the collection adsorption tube when collecting indoor air.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: a portable indoor environmental monitoring and sampling device, including a base, a caster wheel at the bottom of the base, an inverted U-shaped bracket at the top of the base, a height adjustment device that passes through the bracket at the top of the base, a collector connected to the top of the height adjustment device, an exhaust fan inside the collector, an air vent mesh on the side wall of the collector, a detachable collection device at the top of the collector, and a partition assembly inside the detachable collection device.

[0006] Furthermore, the height adjustment device includes a motor, which is fixedly connected to the upper end face of the base. The output end of the motor is provided with a lead screw. The top wall of the bracket is provided with a lifting cylinder that is threadedly engaged with the lead screw. The bottom of the lifting cylinder is provided with an end plate. Two sets of guide rods are fixedly connected between the upper end face of the base and the top wall of the bracket, and the lifting cylinders are arranged symmetrically. The guide rods pass through the end plates. By rotating the lead screw, the lead screw drives the lifting cylinder to rise and fall in the bracket, thereby enabling the collection of air at different heights.

[0007] Furthermore, the detachable collection device includes a collection bucket with its upper and lower ends connected. The upper end of the collection bucket has an internal thread, and the lower end has an external thread. The collector has a threaded hole that matches the external thread at the lower end of the collection bucket. A side block is fixed to the side wall of the collection bucket, and a threaded cap is connected to the side block by a rope. The threaded cap has a handle. The threaded cap is threaded to the upper and lower ends of the collection bucket, respectively, and the threaded cap can seal both ends of the collection bucket to prevent the collected air from leaking out.

[0008] Furthermore, the partition assembly includes a support plate fixed to the collection bucket. The support plate has evenly distributed ventilation holes. By adding activated carbon to the collection bucket, the support plate can support the activated carbon and prevent it from falling off.

[0009] Furthermore, the threaded cap has a handle on its outer wall and a sealing ring fitted on its outer wall to improve the sealing effect.

[0010] Furthermore, the airflow channel of the collector's exhaust fan is sequentially connected to the internal cavity of the collection barrel and the air outlet mesh.

[0011] The beneficial effects achieved by adopting the above-described structure are as follows:

[0012] 1. This utility model, by setting a height adjustment device, uses a motor to drive a lead screw to rotate, and the lead screw to drive a lifting cylinder to rise and fall in the bracket, thereby adjusting the height of the collector and collecting air samples at different heights.

[0013] 2. This utility model features a detachable collection device. By screwing the lower end of the collection bucket into the threaded hole in the collector, the collection bucket can be quickly installed and removed, making it convenient to replace different collection buckets for collection.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] like Figure 1-4 This utility model discloses a portable indoor environmental monitoring and sampling device, including a base 1, with casters 2 at the bottom of the base 1, an inverted U-shaped bracket 3 at the top of the base 1, a height adjustment device 4 extending upward through the bracket 3 at the top of the base 1, a collector 5 connected to the top of the height adjustment device 4, an exhaust fan inside the collector 5, an air vent mesh 6 on the side wall of the collector 5, a detachable collection device 7 at the top of the collector 5, and a partition assembly 8 inside the detachable collection device 7.

[0022] like Figure 1-3 The height adjustment device 4 includes a motor 9, which is fixed to the upper end face of the base 1. A lead screw 10 is provided at the output end of the motor 9. A lifting cylinder 11 passes through the top wall of the bracket 3 and is threadedly connected to the lead screw 10. An end plate 12 is provided at the bottom of the lifting cylinder 11. Two sets of guide rods 13 are fixed between the upper end face of the base 1 and the top wall of the bracket 3 and are symmetrically arranged with the lifting cylinder 11. The guide rods 13 pass through the end plate 12. By rotating the lead screw 10, the lead screw 10 drives the lifting cylinder 11 to rise and fall in the bracket 3, thereby collecting air at different heights.

[0023] like Figure 1-3The detachable collection device 7 includes a collection bucket 14, which is connected to the upper and lower ends. The upper end of the collection bucket 14 is provided with an internal thread, and the lower end of the collection bucket 14 is provided with an external thread. The collector 5 is provided with a threaded hole 15 that matches the external thread at the lower end of the collection bucket 14.
