Referring to fig. 1-4, an adjustable aspirator comprises a negative pressure pump, a liquid accumulation box 1, a conduit, an aspiration tube 2, a controller 3, a gate valve 4, a sleeve 5, a liquid baffle 6, a one-way valve 7 and an aspiration connector 8 (wherein the negative pressure pump and the conduit are not shown in the drawing). The upper end of hydrops case 1 is provided with gas vent 11, and gas vent 11 passes through the pipe and links to each other with the negative pressure pump, when starting the negative pressure pump, can bleed to the inside of hydrops case 1. A liquid inlet 12 and a liquid outlet 13 are arranged on the liquid accumulating box 1, the liquid inlet 12 is positioned at the upper part of the outer side wall of the liquid accumulating box 1, the liquid inlet 12 is communicated with one end of the suction tube 2, and when the negative pressure pump is started, the contents generated in the operation process can be sucked into the liquid accumulating box 1 through the other end of the suction tube 2; the liquid outlet is arranged at the outer side of the bottom of the liquid accumulating box 1, the on-off of the liquid outlet is controlled through a gate valve 4 arranged on the liquid outlet, and when the gate valve 4 is opened, the contents in the liquid accumulating box 1 can be quickly discharged; the inner bottom surface 14 of the liquid storage tank 1 may be inclined toward the position of the liquid outlet 13 so that the content remains in the liquid storage tank 1.

As shown in fig. 3, the controller 3 includes a body 31, an adjusting knob 32 and a display 33, the body 31 is sleeved on the suction tube 2, the adjusting knob 32 and the display 33 are both disposed on the body 31, and the input power of the negative pressure pump can be adjusted and controlled by the adjusting knob 32, so as to adjust the suction force of the suction tube 2, and the working level of the negative pressure pump can be displayed in real time by the display 33 (the higher the working level of the negative pressure pump is, the greater the suction force of the suction tube 2 is, or vice versa), so as to record and count the suction force, which is beneficial to mastering the range of the suction force in the same type of operation, and is beneficial to accelerating the adjusting efficiency of the suction force in the same type of operation. It should be noted that the body 31, the adjusting knob 32, the display 33, and the negative pressure pump themselves and the circuit connections therebetween are all in the prior art, and therefore, they are not described herein again.

In order to avoid that the content in the liquid accumulating box 1 enters the exhaust port 11 due to the splash generated in the liquid accumulating box 1, the sleeve 5 is arranged in the liquid accumulating box 1, and the upper end of the sleeve 5 is communicated with the exhaust port 11; the liquid baffle plates 6 are obliquely arranged inside the sleeve 5, and the two adjacent liquid baffle plates 6 are arranged in a staggered mode. As shown in fig. 2, the three liquid baffles 6 can block the flow to prevent the splashed contents from entering the exhaust port 11; in addition, the liquid baffle 6 is obliquely arranged, so that even if the contents splash into the sleeve 5, the contents gradually flow back to the liquid accumulation box 1 along the liquid baffle 6 under the action of gravity.

In order to prevent the contents in the hydrops tank 1 from flowing out through the suction tube 2 during use, the check valve 7 is provided on the suction tube 2, and the check valve 7 can limit the contents in the hydrops tank 1 from flowing out through the suction tube 2. The check valve 7 is preferably a Tesla valve, and because the Tesla valve has one-way conductivity, and no moving part is arranged in the Tesla valve, only one cavity is formed, and the corrosion of contents to the inside of the check valve 7 is slow, so that the service life of the check valve 7 is prolonged. While other check valves 7 generally have rubber seals inside, and the rubber seals are corroded quickly by the contents, which reduces the service life of the check valve 7.

A plurality of suction connectors 8 are arranged, one end of each suction connector 8 is provided with a connecting port 81, the connecting ports 81 are detachably connected to one end, far away from the liquid accumulation box 1, of the suction tube 2, and the suction tube 2 and the connecting ports 81 can be detachably connected in an interference fit or clamping or screwing mode; the other end of the suction joint 8 is a circular truncated cone structure 82, and the caliber of one end of each circular truncated cone structure 82 far away from the connecting port 81 is different; the suction tube 2 is detachably connected to the connection port 81 so that the suction joints 8 having different diameters are attached to the suction tube 2 depending on the operation site.

The foregoing has described the general principles, essential features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and these changes and modifications are intended to be within the scope of the application as claimed.
