It should be noted that the inlet of the suction nozzle 21 in the present application refers to the opening of the suction nozzle 21 near the barrel 1. Similarly, the inlet of the liquid suction nozzle 22 described below refers to an opening on the side of the liquid suction nozzle 22 close to the tub 1.

The cap body 2 further comprises a spill-preventing member 23, the spill-preventing member 23 having a floating end 231 and a sealing end 232, the sealing end 232 of the spill-preventing member 23 being disposed in the mounting chamber 24 so as to be movable up and down, the floating end 231 of the spill-preventing member 23 extending downward out of the mounting chamber 24. The floating end 231 is adapted to float on a liquid surface and the closed end 232 is adapted to close the inlet of the suction nozzle 21. The upper surface area of the closed end 232 is larger than the area of the inlet of the suction nozzle 21. When the liquid level in the tub 1 is not in contact with the floating end 231 of the overflow preventing member 23, the sealing end 232 of the overflow preventing member 23 is positioned at the lower end of the installation chamber 24 due to its own weight and is separated from the inlet of the suction nozzle 21, and at this time, the inside of the tub 1 can be communicated with the negative pressure device through the suction nozzle 21, thereby achieving a suction function. When the liquid level in the barrel body 1 rises to contact with the floating end 231, the anti-overflow part 23 moves upwards along with the liquid level, so as to drive the sealing end 232 to move upwards to seal the inlet of the air suction nozzle 21, and at the moment, the liquid collection cavity is not communicated with the negative pressure device any more, namely, liquid suction is stopped.

This application utilizes anti-overflow part 23 can avoid the waste liquid in the staving 1 to spill over.

Preferably, a liquid baffle 29 is further provided on the inner side of the cover body 2 between the inlet of the liquid suction nozzle 22 and the mounting chamber 24, and the liquid baffle 29 can prevent the sucked liquid from splashing into or being sucked into the mounting chamber 24.

Further, the cover 2 further includes a suction nozzle sealing cover and a liquid suction nozzle sealing cover (not shown), the suction nozzle sealing cover is detachably covered on the suction nozzle 21, and the liquid suction nozzle sealing cover is detachably covered on the liquid suction nozzle 22. After the liquid suction operation is finished, the suction nozzle 21 and the liquid suction nozzle 22 are respectively sealed by the suction nozzle sealing cover and the liquid suction nozzle sealing cover, so that liquid can be prevented from splashing when the liquid collecting device is carried.

Preferably, the cover 2 also comprises an alarm unit comprising an air chamber 25 arranged outside the cover 2 and adjacent to the outer side wall of the suction nozzle 21. The outer side wall of the suction nozzle 21 adjacent to the air chamber 25 is provided with a first through hole 211, and the first through hole 211 communicates the interior of the suction nozzle 21 with the air chamber 25. It is worth mentioning that the first through hole 211 is located above the inlet of the suction nozzle 21. The air chamber 25 has a second through hole 251 at a side opposite to the first through hole 211, the second through hole 251 communicating the air chamber 25 with the outside.

The alarm unit further includes a shutter 26 movably disposed in the air chamber 25, the shutter 26 being movably disposed at the first through hole 211 for opening or closing the first through hole 211. It will be appreciated that the air chamber 25 communicates with the suction nozzle 21 when the shutter 26 opens the first through hole 211, and the air chamber 25 does not communicate with the suction nozzle 21 when the shutter 25 closes the first through hole 211.

The cover body 2 is further provided with a third through hole 252 between the air chamber 25 and the mounting chamber 24, the sealing end 232 of the spill-proof member 23 is provided with a thimble 233, when the sealing end 232 of the spill-proof member 23 seals the inlet of the air suction nozzle 21, the thimble 233 penetrates through the third through hole 252 to drive the baffle 26 to displace, so that the baffle 26 moves to a position where the first through hole 211 is opened, at this time, the negative pressure device sucks air from the outside through the air chamber 25, and when the air flow passes through the air chamber 25, sound is generated due to vibration of the air flow, thereby achieving the purpose of reminding an operator.

It is worth mentioning that the alarm unit not only plays a role of reminding an operator, but also plays a role of protecting the negative pressure device. When the inlet of the suction nozzle 21 is closed, the internal air pressure will be lower and lower without other air inlets, possibly damaging the negative pressure means or the liquid collecting means. This application is through setting up air chamber 25 for when air exhaust mouth 21 entry was sealed, air exhaust mouth 21 still can be bled from the outside of album liquid device through air chamber 25, ensures negative pressure device's normal operating.

Preferably, a small sounding ball 27 is further disposed in the air chamber 25 to further ensure that a loud sound can be given to indicate to an operator that the liquid collection chamber is full when the air flow passes through the air chamber 25.

Preferably, the inner wall of the installation chamber 24 has a positioning groove (not shown), and the side surface of the sealing end 232 has a positioning boss matching with the positioning groove, and the positioning boss is slidably disposed in the positioning groove up and down, so that the sealing end 232 does not rotate when moving up and down in the installation chamber 24, and the thimble 233 is always kept aligned with the third through hole 252.

Preferably, the shutter 26 is held in a position closing the first through hole 211 by an elastic member 28. That is, in normal use, when the sealing end 232 of the spill prevention member 23 does not seal the inlet of the suction nozzle 21, the flap 26 is always kept in the closed position by the elastic member 28, and the air chamber 25 does not perform ventilation. When the sealing end 232 of the spill prevention member 23 closes the inlet of the suction nozzle 21, the baffle 26 is pushed open by the ejector pins 233, the first through hole 211 communicates the suction nozzle 21 with the air chamber 25, and the air flow enters the air chamber 25 through the second through hole 251 and then enters the suction nozzle 21 through the first through hole 211.

Preferably, the barrel body 1 is a foldable barrel body, and the side wall of the barrel body 1 is suitable for being folded or unfolded, so that the liquid collecting device is portable and easy to store. The tub body 1 has a bung 11 made of a hard material, and the lid body 2 is detachably connected to the bung 11.

In some embodiments, the bottom surface of the barrel 1 is made of hard material, and the side wall is made of silica gel. The bung hole 11 of staving 1 has certain degree of depth, therefore when folding the lateral wall, lateral wall and bucket bottom can be accomodate in the space of bung hole 11 to greatly reduced the volume of staving 1. It is worth mentioning that the side wall of the barrel body 1 has better self-supporting capability, and when the side wall is unfolded, the barrel body 1 can play the same function as a common liquid collecting barrel.
