End is equipped with spiral salient.
Through the above technical solutions, when L-shaped inlet tube and rubber tube are socketed, spiral salient can make L-shaped inlet tube with
The more fastening of rubber tube socket, prevents rubber tube from coming off.
The utility model is further arranged to：The cavity upper end of the catheter is equipped with circular cavity.
Through the above technical solutions, anti-suck plug is understood some liquid and is had passed through before block liquid refluence
Opening, at this moment flowing through the partially liq of opening can be stored in circular cavity, will not suck-back return reaction unit in.
The utility model is further arranged to：The limit protrusion spacing to anti-suck plug is equipped with the cavity.
Through the above technical solutions, liquid can drive anti-suck plug to move downward when flowing through catheter, at this moment protrusion can be with
Fill in that row is spacing to anti-suck, prevent anti-suck plug from blocking the leakage fluid dram of cavity lower end.
The utility model is further arranged to：The tube body bottom is arc-shaped.
Through the above technical solutions, when the liquid in catheter is after the outflow of catheter lower end, certain pressure can be carried,
Tube body bottom is designed as arc-shaped, can reduce impact force of the liquid to tube body bottom.
The utility model is further arranged to：The tube body upper side is equipped with drain pipe, and the drain pipe is away from tube body
One end is equipped with spiral salient.
Through the above technical solutions, when drain pipe is socketed with rubber tube, spiral salient can make drain pipe and rubber sleeve
The more fastening connect, prevents rubber is crossed from coming off.
In conclusion the utility model has the advantages that：
1st, cavity is equipped with the catheter of the utility model, cavity is equipped with anti-suck plug, when drain intraductal pressure is small, prevents
Suck-back plug is moved by water with upward, at this moment raised to be touched with opening, can be blocked opening, be prevented the liquid dress of falling sucting reaction
In putting；
2nd, anti-suck is equipped with frosted protrusion beyond the Great Wall, and frosted opening is equipped with cavity, and frosted protrusion is touched with frosted opening, made
Raised and opening seals more preferable, can prevent liquid from flowing backwards along the raised gap between opening to go back；
3rd, the cavity upper end of catheter is equipped with circular cavity, and anti-suck plug understands some before block liquid refluence
Liquid has had passed through opening, at this moment flows through the partially liq of opening and can be stored in circular cavity, will not suck-back time reaction
In device.

Embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment：A kind of oil vacuole device, as shown in Figure 1, including tube body 1, is connected with L-shaped feed liquor at the top of the upper end of tube body 1
Pipe 11, is equipped with spiral salient 4 in end of the L-shaped inlet tube 11 away from tube body 1, drain pipe is connected with 1 upper end side wall of tube body
12, drain pipe 12 and tube body have a certain distance between 1 top, and spiral salient 4 also is provided with drain pipe 12, is set in tube body 1
There is catheter 2, catheter 2 penetrates through whole tube body 1, and 2 upper end of catheter is connected with L-shaped inlet tube 11, and lower end connects with 1 bottom of tube body
Closely, 1 bottom of tube body is arc-shaped.
As shown in Figure 1, catheter 2 divides for two parts, Part I catheter 21 is connected with L-shaped inlet tube 11, first
