The sputum sample pretreatment device of claim 7, wherein: the top end of the piston (502) extends out of the piston cavity (501) to form a clamping joint (503), the clamping joint (503) is in butt joint with a hole in an extending part (207) of a sealing cover (205) on the cup body (201), and when the sputum taking cup (2) is placed into the accommodating cavity (302), the extending part (207) drives the clamping joint (503) to push the piston (502) downwards, so that the composite enzymatic hydrolysate in the piston cavity (501) is extruded into the cup body (201), and is mixed with a sputum sample to be pretreated.
9. The sputum sample pretreatment device of claim 7, wherein: the top end of the piston cavity (501) is provided with a sealing plug (506).
10. The sputum sample pretreatment device of claim 7, wherein: the free end of the liquid discharge pipe (504) is detachably connected with a disposable puncture tube (505), and the disposable puncture tube (505) punctures the disposable injection hole (206) and enters the cup body (201) in the process of putting the sputum taking cup (2) into the accommodating cavity (302).
