On the basis of any of the above embodiments, in an embodiment of the present invention, as shown in fig. 11, the detection method further includes:
s5: and judging the components of the liquid according to the first detection signal and the second detection signal.
It should be noted that, since any substance has its corresponding absorption band and excitation band, in the embodiment of the present invention, the second detection signal can also be used to determine the composition of the liquid. When the second detection signal is used to determine the component of the liquid, the second detection signal may be the first detection signal transmitted through the first region, or may be the first detection signal excited by the first region, which is not limited in the present invention, as the case may be.
Specifically, on the basis of the above embodiment, in an embodiment of the present invention, the second detection signal is the first detection signal transmitted through the first region, and the transmission speed of the liquid in the liquid transmission assembly and the composition of the liquid are determined by using the first detection signal transmitted through the first region.

When determining whether or not a specific component is contained in the liquid, the first region may be irradiated with a first detection signal including an optical wavelength band that can be absorbed or excited by the specific component, and whether or not the specific component is contained in the liquid may be determined by detecting whether or not the optical wavelength band that can be absorbed by the specific component or an optical wavelength band generated after excitation by the specific component is included in the second detection signal.

It should be noted that, in any of the above embodiments, when the second detection signal is also used for determining the component of the liquid, the same detection signal can be used to simultaneously achieve the purpose of detecting the transmission speed of the liquid in the liquid transmission assembly and the component of the liquid, thereby improving the practicability of the detection method. However, the present invention is not limited to this, and in other embodiments of the present invention, the detecting method further includes: emitting a third detection signal to the first region of the liquid transport assembly; receiving a fourth detection signal, the fourth detection signal being the third detection signal passing through the first region, and if there is liquid transmission in the liquid assembly, the fourth detection signal being used to determine a composition of the liquid.
It should be noted that, because the liquid storage assembly and the liquid transmission assembly are applied in various environments, the detection of the transmission speed of the liquid in the liquid transmission assembly by using the optical signal may be affected by the change of the brightness of the external light and the change of the color of the liquid components, which may affect the detection accuracy. Further, even when the liquid contains a component required to be protected from light, the transmission speed of the liquid in the liquid transmission module cannot be determined by optical signal detection.

s6: and judging the transmission speed of the liquid through the liquid transmission assembly according to the strength of the second detection signal.
In the embodiment of the present invention, since the ultrasonic signals are reflected on the surfaces of different media to cause signal attenuation due to different acoustic impedances of the ultrasonic signals in the different media, when no liquid passes through the first region in the liquid transmission assembly, the propagation medium of the ultrasonic signals is air, and the ultrasonic signals are hardly attenuated, and when liquid passes through the first region in the liquid transmission assembly, the propagation medium of the ultrasonic signals is added with liquid, so that the ultrasonic signals are reflected on the surfaces of the liquid and the air, and the signal intensity is attenuated, the signal intensity before and after the ultrasonic signals pass through the first region can be used to detect the transmission speed of the liquid in the liquid transmission assembly.

s7: outputting preset information, wherein the preset information is used for representing the transmission speed and/or the liquid composition of the liquid in the liquid transmission assembly. It should be noted that the preset information may be directly the transmission speed of the liquid in the liquid transmission assembly and/or the liquid component, or may be other signals representing the transmission speed of the liquid in the liquid transmission assembly and/or the liquid component, which is not limited in the present invention, and is determined as the case may be.
In summary, the detection method provided in the embodiment of the present invention includes: emitting a first detection signal to a first region of the liquid transport assembly; receiving a second detection signal, wherein the second detection signal is the first detection signal passing through the first region, and if there is liquid transmission in the liquid transmission assembly, the second detection signal can be used to determine the transmission speed of the liquid in the liquid transmission assembly.
