[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1As shown, the stool sampling box includes a box body 1, a box lid 2, a pull-out box 3, and a squeezing device. The box body 1 has a receiving cavity 11 with one open end, which is used to hold the stool sample. The box lid 2 can be placed on the opening to close the receiving cavity 11. The pull-out box 3 is slidably disposed at the bottom of the box body 1 and communicates with the receiving cavity 11, so that the stool sample can fall from the receiving cavity 11 into the pull-out box 3. The squeezing device includes a push rod 41 and a sealing component. The push rod 41 slides vertically through the box lid 2 and can push the stool sample so that the stool sample can fall from the receiving cavity 11 into the pull-out box 3. The sealing component is sleeved on the push rod 41 and can seal the push rod 41 with the box lid 2. Understandably, the stool sampling box holds the stool sample in the receiving cavity 11 of the box body 1. The opening of the receiving cavity 11 can be sealed by the box lid 2, which can reduce the leakage of stool odor. At the same time, the stool sample in the receiving cavity 11 can be pushed into the pull-out box 3 below the receiving cavity 11 by the push rod 41, which is convenient for sampling. The push rod 41 and the box lid 2 are sealed by a sealing component, which can ensure the sealing effect of the box body 1 and further reduce the leakage of stool odor. In addition, the push rod 41 and the box lid 2 slide together. When sampling is needed, the push rod 41 can be pushed. The operation is simple, the sampling is convenient and accurate, and the assembly is convenient.

[0032] Optionally, the lid 2 is provided with a cylinder 21, which extends vertically into the receiving cavity 11. The push rod 41 slides through the cylinder 21, and the sealing component can be located between the push rod 41 and the inner wall of the cylinder 21. In this embodiment, the cylinder 21 and the lid 2 are integrally formed, avoiding gaps between the cylinder 21 and the lid 1, which can reduce the leakage of fecal odor. At the same time, the sliding cooperation between the cylinder 21 and the push rod 41 can guide the movement of the push rod 41, making it easier to push the push rod 41. In addition, during the movement of the push rod 41, the sealing component can be located between the push rod 41 and the inner wall of the cylinder 21, which can play a sealing role and further reduce the leakage of fecal odor. The length of the cylinder 21 can be adapted to the length of the push rod 41.

[0033] In this embodiment, a handle is provided at the top of the push rod 41, which makes it easier to push the push rod 41. In other embodiments, the handle may not be provided, and the push rod 41 may be operated directly.

[0034] Optionally, the sealing assembly includes a first sealing element 43 and a second sealing element 44 fixedly sleeved on the push rod 41. The first sealing element 43 and the second sealing element 44 are spaced apart in the vertical direction. The first sealing element 43 can be located between the push rod 41 and the inner wall of the cylinder 21, and the second sealing element 44 can abut against the lower end face of the cylinder 21. Specifically, the push rod 41 is provided with a circumferential first annular groove and a second annular groove. The first sealing element 43 is sleeved in the first annular groove, and the second sealing element 44 is sleeved in the second annular groove. When the second sealing element 44 abuts against the lower end face of the cylinder 21, the first sealing element 43 abuts against the top surface of the cover 2. This is the initial state of the push rod 41. When the push rod 41 is pushed down, the first sealing element 43 moves together with the push rod 41 to the space between the push rod 41 and the cylinder 21, and the second sealing element 44 moves away from the lower end face of the cylinder 21. It is understood that the first seal 43 and the second seal 44 improve the sealing effect between the push rod 41 and the cylinder 21. Even during the movement of the push rod 41, the first seal 43 ensures good sealing performance, reducing the leakage of fecal odor without affecting the movement of the push rod 41. In this embodiment, both the first seal 43 and the second seal 44 are elastic sealing rings. In other embodiments, other structures may also be used.

[0035] Optionally, the box body 1 is provided with a first channel 12, and the receiving cavity 11 is connected to the pull-out box 3 through the first channel 12. The first channel 12 is coaxially arranged with the push rod 41. It can be understood that when the push rod 41 pushes the stool sample, the stool sample can enter the pull-out box 3 through the first channel 12. The size of the first channel 12 should be slightly larger than the outer diameter of the push rod 41 to ensure that the push rod 41 can enter the first channel 12 and the stool sample can fall smoothly into the pull-out box 3. In this embodiment, the box body 1 is also provided with a second channel 13, which is connected to the first channel 12 and the second channel 13. The second channel 13 is connected to the pull-out box 3. The inner diameter of the second channel 13 is smaller than the inner diameter of the first channel 12, which can ensure that the push rod 41 cannot enter the second channel 13, thereby preventing the push rod 41 from being pushed into the pull-out box 3.

[0036] Optionally, the bottom of the receiving cavity 11 is inverted conical, and the first channel 12 is located at the bottom of the receiving cavity 11 and is concentrically arranged with the bottom of the receiving cavity 11. It is understood that the inverted conical shape of the receiving cavity 11 ensures that the sample slides down the cavity wall to the bottom of the cavity and falls into the pull-out box 3 through the first channel 12 and the second channel 13. In other embodiments, the bottom of the receiving cavity 11 may also be other shapes.

[0037] Optionally, a fixing block 42 is provided at the bottom of the push rod 41. The push rod 41 can move to allow the fixing block 42 to enter and exit the first channel 12. The fixing block 42 can push the stool sample to fall from the receiving cavity 11 into the pull-out box 3. Specifically, the fixing block 42 is provided with a connecting rod 421, which passes through the push rod 41 and is interference-fitted with the push rod 41. It can be understood that the fixing block 42 can prevent the push rod 41 from directly contacting the stool sample, thus preventing wear caused by prolonged contact with the stool sample and affecting its service life. The fixing block 42 is easy to replace; only the connecting rod 421 needs to be pulled out of the push rod 41, and the replacement cost is low. In this embodiment, the fixing block 421 is a rubber block, and the connecting rod 421 is also made of rubber and is integrally set with the fixing block 42, which can ensure the reliability of the connection. In other embodiments, the fixing block 42 and the connecting rod 421 can also be made of other materials, or the fixing block 42 can be omitted.

[0038] Optionally, the stool sampling box also includes a shovel 5, which is detachably connected to the lid 2. The shovel 5 extends vertically and is located within the receiving cavity 11. Specifically, the bottom of the shovel 5 can fit into the cavity wall of the receiving cavity 11, and a sealing ring is provided at the connection between the shovel 5 and the lid 2. Stool samples can be taken from the receiving cavity 11 using the shovel 5, which is simple and convenient to use. In other embodiments, the shovel 5 may not be provided.

[0039] Optionally, the bottom of the box body 1 is provided with a pull-out groove, and the bottom of the pull-out groove is provided with a guide groove along the pull-out direction. The bottom of the pull-out box 3 is provided with a guide rail 31, and the guide rail 31 and the guide groove are slidably engaged along the pull-out direction. It can be understood that the sliding engagement between the pull-out box 3 and the pull-out groove through the guide rail 31 and the guide groove can guide the pull-out of the pull-out box 3, prevent the pull-out box 3 from getting stuck during the pull-out process, and ensure the pull-out effect. In other embodiments, other structures such as sliding rods and sliding sleeves can be used instead of the guide rail 31 and the guide groove.

[0040] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
