Further, one or both of the containment cap 22 and the shroud 26 include the use of a sealing material, such as a gasket 46; alternatively, the seal 46 may be formed from any suitable sealing material or mechanism; the gasket 46 functions to form an airtight seal between the airtight cover 22 and the shield 26 and prevent air from entering the collecting basin 14 from outside the collecting basin 14 to prevent air pressure from being insufficient due to air leakage of the collecting basin 14 when compressed air is introduced or to prevent external air from entering the collecting basin 14 from outside to cause insufficient negative pressure when negative pressure is generated to the collecting basin 14 using the vacuum generating module.
Further, as shown in FIG. 2, when the closure cap 22 is closed, the shield 26 enters the collection basin 14 through the receiving end 50 of the upper portion of the collection basin 14; although not shown in fig. 1 and 2, the fixture may also include a magnetic switch, a rebound mechanism, a buffer mechanism or other mechanism, if desired, designed to communicate with the spray module, air pressure module, vacuum generating module or shut-off valve 18 to prevent the above modules or components from being triggered to operate before the closure cap 22 is closed; preferably, the control signal is generated by a magnet disposed in the hermetic cover 22 and a corresponding magnetic switch disposed below the shield 26, which when contacted, allows the rest of the detection system to be activated and operated.
When the collection basin 14 is rinsed, a small amount of water and a large amount of compressed air enter the collection basin 14 at the distribution ring 34, mix, and are discharged out of the end 42 as the collection basin 14 empties; when the compressed air passes through the inner surface of the collecting basin 14, the structure inside the distribution ring 34 is matched with the air inlet holes 38, so that the high-speed air flow generates an air knife effect, and the flow speed of water is accelerated; the compressed air and the accelerated water provide a more efficient condition for removing the contents of the collection basin 14, and a small amount of flushing water maintains the basic properties of the feces while saving water usage.
Meanwhile, because the closed cover 22 is in a closed state during the flushing of the collecting basin 14, most of noise generated during the flushing of the collecting basin 14 is isolated, and the noise control during the operation of the detection system is effectively maintained.
Embodiment two: this embodiment should be understood to include at least all of the features of any one of the preceding embodiments, and be further modified based thereon;
when the faeces are driven into the first conduit 28, the shut-off valve 18 is closed and all or at least part of the faeces is allowed to rest in the first conduit 28; the detection unit 40 starts the first processing to sample.
An exemplary embodiment of the detection section 40 is illustrated in fig. 3.

Further, both ends of the spindle 58 are supported by elastic members; when the movable slide 56 moves toward the inlet channel and over the entrapment unit 54, the movable slide 56 will cause the entirety of the entrapment unit 54 to be pressed into the interior of the detection section 40; conversely, when the movable slide 56 opens the inlet channel, the resilient member of the catch unit 54 lifts under its return force and thereby causes the appropriate portion of the catch piece 60 to enter the interior of the first conduit 28.
Further, the rotating spindle 58 is driven so that the catch piece 60 starts to toggle the content, such as faeces, inside the first tube 28; the faeces are then driven into the detection portion 40 and fall into the storage chamber 42.
Preferably, the storage chamber 42 includes a sensor, such as a pressure sensor, for measuring the weight of the sample in the storage chamber 42, and measuring the total weight of the currently acquired sample in real time; if the weight of the sample accords with the preset weight, completing the first processing process and executing the subsequent detection process; if the sample weight does not reach the predetermined weight, the retention unit is driven to continue to withdraw fecal matter from the first conduit 28 until the sample meets the predetermined weight.
Further, to complete the first detection process, various forms of sensors may be used, such as the above-described pressure sensor, temperature sensor, hardness sensor, etc., and include an image sensor, a pressure sensor, etc., provided inside the collecting tub 14.
In some preferred embodiments, the total weight of the contents of the collection portion can be first acquired at a first time inside the collection tub 14, and an image is acquired by the image sensor regarding the stool, judging the basic property of the stool, such as a strip, a grain, or a paste, thereby providing a basis for the subsequent setting of the value of the property score p.
And is included in said storage chamber 42 at a first instant t 1 First temperature Tep of sample 1 And at t 1 Later time t of (2) 2 Alternatively, in performing the second detection process, for example, t is set 2 At t 1 After 30 seconds of (2), a second temperature Tep of the sample was obtained 2 Thus calculating the temperature drop rate of the feces.
After the first detection process is completed, a contact sensor can be further used for extending into the sample to perform more complex detection such as the water content, hardness, leucosis, colony type and the like of the sample, and allow the sample to be partially changed in properties, decomposed and the like; the specific implementation of the second detection process is selected and set by the relevant technician.
Further, the detection data obtained in the first detection process and the second detection process are transmitted to the processing part for processing.
Illustratively, as shown in fig. 4, an architecture diagram of the processing portion is shown; the processing section includes a processing circuit 100, the processing circuit 100 including a processor 102 and a memory 104; processor 102 may be a general-purpose or special-purpose processor, an Application Specific Integrated Circuit (ASIC), one or more Field Programmable Gate Arrays (FPGAs), a set of processing components, or other suitable processing components; the processor 102 is configured to execute computer code or instructions stored in the memory 104; memory 104 may include one or more devices (e.g., memory units, memory devices, storage devices, etc.) for storing data and/or computer code to accomplish and/or facilitate output of various detection results described in this disclosure; memory 104 may include memory that is Random Access Memory (RAM), read Only Memory (ROM), mechanical memory, temporary storage, flash memory, or other forms of memory; and memory 104 may include database components, object code components, script components, or any other type of information structure for supporting the various activities and information structures described in this disclosure; the memory 104 is communicatively connected to the processor 102 and may include computer code for performing one or more detection processes required by the detection system of the present invention in detecting fecal matter; when the processor 102 executes instructions stored in the memory 104, the processor 102 may control the detection portion of the detection system to complete a specified analysis program action and output a detection result.
Embodiment III: this embodiment should be understood to include at least all of the features of any one of the previous embodiments and be further modified based thereon.
Along with the completion of the detection process, the collection part and the detection part are required to be completely cleaned so as to ensure the cleaning degree of the interior and the independence of the next detection result; thus, the second process is performed to completely clear the inside of the collecting portion and the detecting portion.
In an exemplary embodiment, behind the shut-off valve 18 is a second conduit 29; the second conduit 29 is connected to the vacuum generating module 6 by a separate vacuum conduit 66; the contents discarded by the detection system are processed by a processing device connectable to the outside at the rear end of the second conduit 29; a one-way stop valve 64 is provided at a position after the connection between the vacuum pipe 66 and the second pipe 29, that is, at a connection section between the second pipe 29 and the external environment; the one-way stop valve 64 is used for isolating external air from entering the second pipeline 29 when the vacuum generating module 6 generates negative pressure on the second pipeline 29 and the inside of the detection system in front of the second pipeline 29; at the same time, when there is a gas flowing through the second conduit 29 from the direction of transport 62, this portion of the gas is allowed to pass through the one-way shut-off valve 64.
When the second treatment process is executed, the vacuum generating module 6 performs vacuum generating work, and the air pressure module 2 performs compressed air work; when the vacuum generating module 6 brings the negative pressure inside the second conduit 29 to a predetermined level and the air pressure module 2 is ready to have a sufficient air outlet quantity Q, the shut-off valve 18 is opened, releasing the compressed air of the air pressure module 2 and preferably providing a suitable flushing water in cooperation with the water supply module 4, so that the collecting basin 14 and all the contents inside the first conduit 28 are simultaneously forced to advance in the transport direction 62.
Also, a conduit is preferably provided within the detection portion 40 so that compressed air and flushing water enter the reservoir to purge the sample into the first conduit 28.
Thereafter, the one-way shut-off valve 64 is fully opened and all of the contents flow out of the second conduit 29 with the high pressure air and flush water to complete the entire second process.
