[0033] Specifically, refer to Figure 1 The sampling device 001 of the embodiment of the present disclosure comprises: a housing 100, the housing 100 has different accommodating cavities for accommodating vessels and a water inlet 13, referring to Figure 2 , the water inlet 13 is located on an outer side of the housing 100. The embodiment of the present disclosure does not limit the specific shape of the housing 100, including but not limited to a space with sufficient accommodating chamber required by the sampling device 001 of the embodiment of the present disclosure. Specifically, the sampling device 001 includes a flow control component 10, the housing 100 has a first accommodating chamber, the flow control component 10 is accommodated in the first accommodating chamber, the flow control component 10 is used to control the flow direction of the fluid, and the flow control component 10 can be understood as a diverter. In actual application, the flow control component 10 includes: a stepper motor 11, a diverter three-way valve 12 connected to the stepper motor 11, the first accommodating chamber has a sampling port 21 and a sewage outlet 91 separated from the sampling port 21, and the diverter three-way valve 12 can be opened and closed and connected to the sampling port 21 and the sewage outlet 91; refer to Figure 1 and Figure 3 , we can see the specific positions of the sampling port 21 and the sewage outlet 91. Generally, one of the sampling port 21 and the sewage outlet 91 is in an open state, and the other is in a closed state, thereby realizing the two functions of sampling and sewage discharge respectively. The liquid enters from the water inlet 13, and the diversion valve 12 is used to control the valve to realize the diversion of different water outlets. The different water outlets here can be understood as the sampling port 21 and the sewage outlet 91.

[0034] Considering that the diverter three-way valve 12 can normally start the sampling process, the sampling device 001 also includes a sampling component 20, the sampling component 20 includes a sampling port 21 and a sampling channel 22 connected to the sampling port 21, the housing 100 has a second accommodating chamber, the sampling port 21 and the sampling channel 22 are arranged in the second accommodating chamber, the sampling port 21 is connected to the aforementioned diverter three-way valve 12 in an openable and closable manner, so as to facilitate the control of the opening and closing state of the sampling port 21 by the flow control component 10; specifically, in the pressed state, the elastic pressing switch component 30 is configured to connect the sampling tube with the external collection component, that is, the external collection component is used to make the liquid flow out from the outlet 40; further reference Figure 1 There is a first outlet channel 50 between the elastic pressing switch member 30 and the outlet 40. For details, refer to Figure 1 , Figure 4 and Figure 5The elastic push switch component 30 includes a sampling tube, a tube cap 32 connected to the top of the sampling tube, a tube plug 33 connected to the bottom of the sampling tube, and an elastic member 34 located at the bottom of the tube plug 33. In addition, a first branch channel 60 is provided between the tube plug 33 and the sampling tube, and a second branch channel 70 is provided at the bottom of the elastic member 34. When the elastic push switch component 30 is applied as above, in the pressed state, the first branch channel 60 moves downward and communicates with the sampling channel 22, and the fluid flows to the sampling tube through the first branch channel 60 to complete the sampling process.

[0035] Considering the connection mode between the tube plug 33 and the sampling tube, the tube plug 33 includes a plug head 331 and a plug column 332 connected to the bottom of the plug head 331. The elastic member 34 is sleeved on the outer periphery of the plug column 332. The outer periphery of the plug head 331 has a liquid guide groove 333. The liquid guide groove 333 of the embodiment of the present disclosure includes but is not limited to a groove structure. Specifically, the liquid guide groove 333 is directly connected to the sampling tube. Considering the sealed connection between the two, refer to Figure 5 The top surface of the plug head 331 has a protruding structure 334, and the tube mouth of the collection tube is engaged with the outer edge of the protruding structure 334. In this way, the liquid guide groove 333 is connected with the first branch channel 60 in the pressed state, so as to automatically complete the sampling process.

[0036] In the normal state, the elastic pressing switch member 30 is configured to block the fluid flow path between the sampling tube and the outlet 40. At this time, in the non-sampling state, the sewage discharge process can be carried out. Specifically, the sampling device 001 also includes a sewage discharge member 90, the housing 100 has a third accommodating chamber, and the sewage discharge member 90 is placed in the third accommodating chamber, wherein the sewage discharge member 90 includes the aforementioned sewage discharge port 91 and a sewage discharge pipe 92 connected to the sewage discharge port 91; the sampling device 001 also includes a second outlet channel 80, and the second outlet channel 80 is always connected between the flow control member 10 and the outlet 40; the flow control member 10 is used to control the opening and closing of the sewage discharge port 91, so as to complete the sewage discharge process.

[0037] In consideration of the clean and quick completion of the sewage discharge process, the sampling device 001 of the disclosed embodiment also includes a sewage discharge barrel 110. The outer shell 100 has a fourth accommodating chamber, and the sewage discharge barrel 110 is placed in the fourth accommodating chamber. Specifically, the sewage discharge barrel 110 is connected to the sewage discharge pipe 92 at the outlet 40 to facilitate the completion of the sewage discharge process.

[0038] Considering the portable application of the overall sampling device 001, the sampling device 001 of the embodiment of the present disclosure also includes a top cover (not shown in the figure), which can be rotatably covered on the top of the outer shell 100. Specifically, the top cover can be integrated with control buttons to facilitate monitoring of the performance effectiveness of each component.

[0039] In summary, the flow control component 10, the sampling component 20, the elastic pressing switch component 30 and the sewage discharge component 90 of the embodiment of the present disclosure are all installed in the housing 100, and the overall device is portable and has high cleanliness. The sampling device 001 of the embodiment of the present disclosure adopts the flow control component 10 (which can be understood as a diverter) to control the flow direction of the fluid. In practical applications, the flow control component 10 can set multiple flow outlets 40 according to actual needs, and each flow outlet 40 can be controlled to flow out the fluid separately. One of the basic functions of the sampling device 001 is to sample the fluid sample body. The elastic pressing switch component 30 is used to connect the sampling tube with the external collection component. Specifically, the elastic pressing switch component 30 blocks the fluid flow path between the sampling tube and the outlet 40 in the normal state. When the sampling tube is pressed relative to the elastic pressing switch component 30, the fluid flow path between the sampling tube and the outlet 40 is unblocked and can flow to the sampling tube to complete the sampling process. In this way, the entire collection process is clean and hygienic, which can effectively improve the convenience of collecting stool samples.

[0040] In actual application, when sampling is not required, the valve of the sewage outlet 91 of the diverter three-way valve 12 is controlled to be opened, and the liquid enters the outlet 40 through the second outlet channel 80 and enters the sewage bucket 110. When sampling is required, the valve of the sampling port 21 of the diverter three-way valve 12 is controlled to be opened, and the liquid enters the sampling channel 22 through the sampling port 21 and enters the sampling tube. The sampling tube is connected to the tube plug 332 of the elastic pressing switch component 30. When sampling, the tube cap 32 is pressed, the channel opens and closes, and the liquid enters the sampling tube. After the collection is completed, the tube is lifted up and the channel is closed. The overall sampling process is convenient, fast, clean and hygienic.

[0041] The disclosed embodiment also provides a stool collection device, including the above-mentioned sampling device (001), which is applied in medical equipment and can achieve all the effects of the sampling device (001), which will not be described in detail here.

[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
