Description

Technical Field

[0001] This utility model relates to the field of environmental sampling technology, specifically to environmental sampling transport swabs. Background Technology

[0002] The process of collecting samples from the environment includes sampling from substances such as soil, plants, water, and air. The precise location of environmental samples within the monitoring area is crucial. Based on the stability of sampling points, they can be categorized as fixed sampling points and mobile or random sampling points. Fixed sampling points are mainly used for environmental quality monitoring and surveillance of key pollution sources. Mobile sampling points are non-fixed sampling points selected or randomly located within the monitoring area, primarily used to supplement the deficiencies of fixed sampling points, as well as for some research-based and environmental accident monitoring projects. According to the monitoring project, sampling points can be categorized as atmospheric sampling points, water quality sampling points, biological sampling points, noise sampling points, soil sampling points, solid waste sampling points, and radioactive sampling points. When collecting environmental samples, transport swabs are required; therefore, environmental sampling transport swabs are urgently needed.

[0003] Currently used environmental sampling transport swabs have poor sealing when the swab is inserted into the swab tube for storage after the sample is collected, which can easily lead to leakage of internal solvents or samples. In addition, during the transport of swabs, the swab tubes need to be placed uniformly on a tray, which makes it difficult to distinguish the types of samples inside the swab tubes. Utility Model Content

[0004] The purpose of this invention is to provide an environmental sampling transport swab to solve the problems mentioned in the background art. Currently used environmental sampling transport swabs have poor sealing when the swab collects the sample and is inserted into the swab tube for storage, which can easily lead to leakage of internal solvents or samples. Furthermore, during the transport of the swab, the swab tubes need to be placed uniformly on a tray, which makes it difficult to distinguish the types of samples inside the swab tubes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmental sampling and transport swab, including a swab tube, wherein the bottom of the inner wall of the swab tube contains solvent, and an identification label is provided on the top surface of the swab tube; the top of the swab tube is provided with a tube opening, and a sealing ring is fitted on the bottom of the outer wall of the tube opening; a fixing tube is provided on the top of the inner wall of the tube opening, and a swab head is provided on the top of the fixing tube; a swab handle is provided on the inner wall of the swab head, and a fiber clump is provided at the bottom of the swab handle.

[0006] Preferably, the inner wall of the identification tag is in close contact with the surface of the swab tube, and the size of the identification tag is smaller than the size of the swab tube.

[0007] Preferably, the inner wall of the sealing ring is in close contact with the outer wall of the pipe opening, and the inner wall size of the sealing ring matches the outer wall size of the pipe opening.

[0008] Preferably, the swab head is threadedly connected to the tube opening via a fixing tube, and both the outer wall of the fixing tube and the inner wall of the tube opening are threaded.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This environmental sampling and transport swab, with its sealing ring and fixing tube, facilitates the collection of environmental samples by inserting the swab handle and the sample-adhered fiber clump into the swab tube for storage. The swab head is rotated to tighten and fix the swab tube opening through the fixing tube. The sealing ring on the outer wall of the tube opening provides a sealing effect at the connection, preventing the internal solvent or sample from leaking due to the swab tube tipping over.

[0011] 2. This environmental sampling transport swab, with its set identification label, facilitates the transfer of samples from the swab tubes. Since there are a large number of sampling swabs, they need to be placed uniformly in a tray. By attaching an identification label to each swab tube and indicating the type of sample inside, operators can easily select the corresponding sample for testing by identifying the sample type marked on the label.

[0016] 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.

[0017] Please see Figure 1-3This utility model provides a technical solution: an environmental sampling transport swab, including a swab tube 1. The bottom of the inner wall of the swab tube 1 contains solvent 2, and an identification label 3 is provided on the top surface of the swab tube 1. The inner wall of the identification label 3 is closely attached to the surface of the swab tube 1, and the size of the identification label 3 is smaller than the size of the swab tube 1. By setting the identification label 3, it is convenient to transport the sample in the swab tube 1. Since there are many sampling swabs, it is necessary to place the swab tubes 1 uniformly in a tray. By attaching the identification label 3 to each swab tube 1 and indicating the sample type in the swab tube 1, the operator can easily select the corresponding sample for testing by identifying the sample type marked on the identification label 3.

[0018] The swab tube 1 has an opening 4 at its top, and a sealing ring 5 is fitted around the bottom of the outer wall of the opening 4. The inner wall of the sealing ring 5 fits tightly against the outer wall of the opening 4, and the dimensions of the inner wall of the sealing ring 5 match the dimensions of the outer wall of the opening 4. A fixing tube 6 is provided at the top of the inner wall of the opening 4, and a swab head 7 is provided at the top of the fixing tube 6. The swab head 7 is threadedly connected to the opening 4 through the fixing tube 6, and both the outer wall of the fixing tube 6 and the inner wall of the opening 4 are threaded. A swab handle 8 is provided on the inner wall of the swab head 7. Furthermore, the bottom of the swab handle 8 is provided with a fiber bundle 9. Through the provided sealing ring 5 and fixing tube 6, it is convenient to collect samples from the environment by swabbing, insert the swab handle 8 and the fiber bundle 9 with the sample into the swab tube 1 for storage, and tighten and fix it to the tube opening 4 of the swab tube 1 by rotating the swab head 7 through the fixing tube 6. The sealing ring 5 on the outer wall of the tube opening 4 can provide a sealing effect at the connection, preventing the internal solvent 2 or sample from leaking due to the swab tube 1 tipping over.

[0019] Working principle: When sampling and testing the environment, the environmental sample is first collected through the fiber tuft 9 at the front end of the swab handle 8. Then, the swab handle 8 and the fiber tuft 9 with the sample are inserted into the swab tube 1 for storage. The swab head 7 is rotated to tighten and fix the tube 1 to the tube opening 4 through the fixing tube 6. The sealing ring 5 on the outer wall of the tube opening 4 provides a sealing effect at the connection to prevent the internal solvent 2 or sample from leaking due to the swab tube 1 tipping over. When transferring the sample in the swab tube 1, since there are many sampling swabs, the swab tubes 1 need to be placed in a tray. By attaching an identification label 3 to each swab tube 1 and indicating the sample type in the swab tube 1, the operator can easily select the corresponding sample for testing by identifying the sample type marked on the label 3. This completes the operation process of transporting environmental sampling swabs.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
