The cover 2 includes a cover body 21 formed in a substantially flat plate shape, a recess 22 having a recess wall 220 formed in a recess in a surface of the cover body 21, a through hole 23 formed in the recess wall 220 of the recess 22, and a liquid inlet 24 having a tip 241 disposed in the recess 22. In an embodiment, the cover 2 further includes a handle 26 and a cover 27, the handle 26 is used for lifting the cover 2 to close the opening 31 of the main body 3, and the cover 27 is used for sealing the groove 22, where two modes of setting the handle are provided, one mode is shown in fig. 2, the handle is parallel to the direction in which the width of the cover body 21 is located, and another mode is shown in fig. 3, the handle is parallel to the direction in which the length of the cover body 21 is located.
The lid body 21 is composed of two areas, namely, a peripheral area 211 defining the outline shape of the outer periphery of the lid body 21 and a peripheral area 212 surrounding the periphery of the recess 22.
In the cover 2 shown in fig. 2, 3 and 4, the recess 22 is specifically disposed at a position far from the center of the cover body 21, and the disposition position shown in fig. 2, 3 and 4 is the optimum disposition position in one embodiment, and the medical waste liquid flows into one end of the main body 3 from the liquid inlet 24, gradually covers the bottom of the main body 3 and fills the whole main body 3, so that the gas in the main body 3 can be discharged, however, in other embodiments, the recess 22 may be disposed at the center of the cover body 21, if the above-mentioned effect of the gas in the main body 3 is not considered.
The groove wall 220 of the groove 22 has: a bottom wall 221 and a side wall 222 provided around the bottom wall 221; the tail end 241 of the liquid inlet part 24 is communicated with the bottom wall 221 of the groove 22; the through hole 23 is formed in a sidewall 222 of the recess 22.

In other embodiments not shown, the side walls 222 of the recess 22 may have an inverted truncated cone shape, a cylindrical shape, a conical shape, or an irregular three-dimensional shape having the side walls 222 and the bottom wall 221. In the shape of the groove 22 in the cover 2 shown in fig. 2 and 3, the groove 22 is disposed around the end 241 of the liquid inlet portion 24; the top surface of the groove 22 is circular, and the side wall 222 of the groove 22 is an arc surface protruding to the outside of the groove 22. In the embodiment shown in fig. 2 and 3, when the return pipe of the water jet device connected to the liquid inlet portion 24 is pulled out, even if the amount of the medical waste liquid flowing into the groove 22 is excessive, most of the through holes 23 are blocked, but the sectional area through which the gas can flow in the main body portion 3 is relatively large compared with the straight tubular structure or the conical structure, and the gas discharge effect is better. The number of the through holes 23 provided in the side wall 222 of the recess 22 may be 18 as shown in fig. 2,3 and 4, and the number of the through holes 23 is not limited to the number shown in fig. 2,3 and 4, and the number of the through holes 23 may be specifically configured according to the capacity of the main body 3 and the size of the recess 22.

It should be noted that, the opening manner of the plurality of through holes 23 is not limited to the opening manner shown in fig. 2 and 3, and the plurality of through holes 23 may be arranged orderly or unordered or uniformly or unevenly around the sidewall 222 of the groove 22, for example: each through hole 23 is provided parallel to the bottom wall 221 of the recess 22, and each through hole 23 is equidistant from the bottom wall 221 of the recess 22; or each through hole 23 is provided parallel to the bottom wall 221 of the recess 22, each through hole 23 being at a different distance from the bottom wall 221 of the recess 22; or each through hole 23 is provided parallel to the bottom wall 221 of the recess 22, and the interval between two adjacent through holes 23 is equal; or each through hole 23 is provided parallel to the bottom wall 221 of the recess 22, and the interval between two adjacent through holes 23 is unequal; or each through hole 23 is arranged at an included angle with the bottom wall 221 of the groove 22, and two adjacent through holes 23 are parallel to each other and have equal spacing; or each through hole 23 is disposed at an angle to the bottom wall 221 of the recess 22, and two adjacent through holes 23 are not parallel to each other and are not equally spaced, and other arrangements are not illustrated herein. The opening of the through hole 23 shown in fig. 2 and 3 is performed in a manner that is larger in the through hole 23 than in the other embodiments, and is more advantageous for gas discharge than in the through hole 23 of the other embodiments, when the return pipe connected to the liquid inlet portion 24 is pulled out and the medical waste liquid of the same volume flows into the recess 22 to block most of the through hole 23, as compared with the opening of the other embodiments shown in fig. 2 and 3.
In another embodiment, the cover 2 further includes: a plurality of exhaust film bodies 25; the number of the film bodies 25 is the same as that of the through holes 23, and each film body 25 correspondingly covers one through hole 23. The membrane body 25 is a vent membrane, and the vent membrane is preferably a hydrophobic vent membrane, which has the characteristics of no absorption of moisture and excellent air permeability, and has a smaller resistance to air than a general vent membrane. The membrane 25 is waterproof and breathable, and prevents external solid particles from penetrating through the through holes 23 and entering the main body 3, thereby playing a role in bacterial inhibition.
The top view contour of the liquid inlet portion 24 is circular in fig. 2 and 3, and the liquid inlet portion 24 is entirely straight, but the shape shown in fig. 2 and 3 is not limited by the present invention, and the top view contour of the liquid inlet portion 24 may be circular, square, triangular or other irregular shape, no matter what the top view contour of the liquid inlet portion 24 is, the end 241 of the liquid inlet portion 24 is located inside the groove 22, and the end 241 of the best liquid inlet portion 24 is located at the center of the bottom of the groove 22. In addition, in other embodiments, the liquid inlet 24 may be bent, and when the liquid inlet 24 is bent, the tip of the liquid inlet 24 is located in the groove 22 in the plane of the liquid inlet 24. Thus, when the return pipe of the water jet device connected to the liquid inlet portion 24 is pulled out, the medical waste liquid does not flow out but flows into the groove 22, and external pollution is prevented.
