[0002] With the development of medical testing technology, the demand for excrement samples for disease screening and health monitoring has surged. Toilets, as the core sampling medium, have become crucial for sample compatibility. However, existing toilet sampling methods suffer from bottlenecks such as low efficiency and poor sample quality, severely hindering the implementation of testing technologies. This is mainly because toilet bowls are mostly open-style with large volumes, resulting in scattered excrement distribution during quantitative sampling, making it difficult to accurately obtain a sufficient sample volume. Therefore, developing auxiliary devices that improve sampling accuracy and are highly compatible with toilets has become a critical need.
[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0004] The present invention includes a series of simplified concepts, which will be further explained in detail in the detailed description section. This present invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.
[0005] One of the main objectives of this utility model is to overcome at least one of the defects of the prior art and to provide an auxiliary sampling device for toilets and a sampling toilet.
[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: According to one aspect of the present invention, an auxiliary sampling device for a toilet is provided, comprising a flow guiding structure for guiding the directional transport of excrement; the flow guiding structure has a first port for receiving excrement and a second port for outputting excrement; the cross-sectional area of the first port is larger than the cross-sectional area of the second port to form a converging transport channel from the first port to the second port.
[0007] According to one embodiment of the present invention, the second port is a neck with a certain length, the first port is an open flared portion, and the radial dimension of the first port gradually tapers from the edge toward the end connected to the neck.

[0030] like Figures 1-2 As shown, this embodiment provides an auxiliary sampling device for toilets, including a flow guiding structure 100 for guiding the directional transport of excrement. The flow guiding structure 100 has a first port 110 for receiving excrement and a second port 120 for outputting excrement. The cross-sectional area of the first port 110 is larger than that of the second port 120, forming a converging transport channel from the first port 110 to the second port 120. In this embodiment, the first port 110 of the flow guiding structure 100 is a funnel-shaped opening, integrally connected to the neck 130. During sampling, the sampling probe of the sampling device 300 is close to the second port 120 for sampling. Specifically, the sampling probe of the sampling device 300 extends below the second port 120 to facilitate the collection of excrement falling below the second port 120. Its advantages are that the converging channel allows the excrement to flow in a concentrated manner, solving the problem of scattered landing points in traditional toilet bowls 210; the sampling probe of the sampling device 300 is close to the converged excrement, which can quickly obtain a sufficient amount of sample; the integrally molded structure reduces the risk of leakage and is simple to operate. Figures 3-5 As shown, in other embodiments, a sampling port 131 is horizontally opened along the side wall of the neck 130 and communicates with the interior of the neck 130. The sampling probe of the sampling device 300 performs sampling by extending into the sampling port 131.
[0031] In some embodiments, such as Figure 1 As shown, the second port 120 is a neck 130 with a certain length, and the first port 110 is an open flared portion 140. The radial dimension of the first port 110 gradually narrows from the edge to the end connected to the neck 130.
[0032] In some embodiments, such as Figures 1-2As shown, the outer contour of the flared portion 140 at least partially conforms to the toilet bowl 210. In this embodiment, the outer contour of the flared portion 140 is designed according to the curvature of the mainstream toilet bowl 210, and an adhesive film can be provided at the conforming part to increase the conforming effect with the toilet bowl and ensure that the device does not slip after placement.
[0033] In some embodiments, such as Figures 1-2 As shown, the flared portion 140 is composed of an asymmetrical short edge 141 and a long edge 142, with the outer side of the long edge 142 fitting against the toilet bowl 210. In this embodiment, the connection between the short edge 141 and the long edge 142 is smoothly transitioned, and the outer side of the long edge 142 conforms to the curvature of the inner wall of the toilet bowl 210. Its advantages are that the asymmetrical design precisely matches the natural curvature of the toilet bowl 210, increasing the fitting area compared to a symmetrical structure and effectively solving the problem of device displacement; the long edge 142 has a larger range and can accommodate more excrement from different points.
[0034] In some embodiments, such as Figure 1 As shown, the neck 130 has a circular or non-circular cross-section. When the neck 130 has a non-circular cross-section, one side adopts a flattened structure 133. It can be understood that "non-circular" includes shapes such as elliptical, square, and oval. The "flattened structure 133" is used to reduce the installation space required. The circular neck 130 allows for smoother waste flow and reduces residue; the flattened structure 133 allows for flexible installation within the confined space of the toilet bowl 210, adapting to compact toilets with smaller inner wall curvatures, thus expanding the device's applicability.
[0035] In some embodiments, the flow guiding structure 100 is made of disposable materials. It is understood that "disposable materials" refers to biodegradable plastic or paper materials that meet medical and hygiene standards and can be discarded or flushed away after use. Disposable use completely eliminates the risk of cross-infection, and compared to reusable devices, it eliminates the need for cleaning and disinfection steps, improving sampling efficiency; biodegradable materials meet environmental protection requirements, reducing waste pollution.
[0036] In some embodiments, the inner wall of the flow guiding structure 100 is smoothed, including the inner wall of the flared portion 140 and the inner wall of the neck 130. The smoothing treatment is used to reduce excrement residue. The edge of the flared portion 140 is blunted or rounded to prevent scratches during use.
[0037] like Figures 3-5 As shown, this embodiment provides a sampling toilet 200, with a sampling device 300 at the outlet of its bowl 210. As in any of the above embodiments, the auxiliary sampling device 300 is detachably installed inside the toilet bowl 210, and at this time, the sampling probe of the sampling device 300 is inserted into the auxiliary sampling device 300 through the collection port 131. Specifically, the auxiliary sampling device 300 is detachably installed at the water seal position inside the toilet bowl 210. It can be understood that during installation, if... Figure 2As shown, the long edge 142 fits snugly against the toilet bowl 210, achieving modular assembly. It is directly applicable to traditional toilet samples, requiring no modification to the toilet body, significantly reducing costs; the detachable design also facilitates replacement and maintenance, improving economic efficiency. In use, as... Figure 3 As shown, the sampling probe extends out through the collection port 131 and enters the auxiliary sampling device 300 to perform sampling.
[0038] It should be understood that the various examples described above can be utilized in multiple directions (e.g., tilted, inverted, horizontal, vertical, etc.) and in multiple configurations without departing from the principles of this invention. The embodiments shown in the accompanying drawings are merely examples of effective application of the principles of this invention, and the invention is not limited to any specific details of these embodiments.
[0039] Of course, upon careful consideration of the above description of the representative embodiments, those skilled in the art will readily understand that various modifications, additions, substitutions, deletions, and other changes can be made to these specific embodiments, and that such changes are within the scope of the principles of this invention. Therefore, the foregoing detailed description should be clearly understood as being given by way of illustration and example only, and the spirit and scope of this invention are defined solely by the appended claims and their equivalents.
