Detailed Description

The multifunctional negative pressure drainage device provided by the present invention is further described in detail with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.

Example one

The utility model provides a multifunctional negative pressure drainage device, the structure of which is shown in figure 1, the multifunctional negative pressure drainage device comprises a negative pressure bottle 1, a numerical pressure gauge 3, a bottle cap 2, a first PPR pipe 11, an adjusting switch 5, a liquid flow meter 6 and a second PPR pipe 4; the numerical pressure gauge 3 is connected to the negative pressure bottle 1 and is used for displaying the pressure value in the negative pressure bottle 1; the bottle cap 2 is arranged on the negative pressure bottle 1; be fixed with on the bottle lid 2 and be used for carminative plastic tubing 8, still the cover has pipe cap 9 on the plastic tubing 8, through pressing negative pressure bottle 1 follows plastic tubing 8 is carminative, and according to numerical pressure table 3 can accurately be adjusted negative pressure bottle 1 reaches required pressure value. The adjusting switch 5 is positioned in the first PPR pipe 11, and the adjusting switch 5 can control the drainage quantity; the liquid flow meter 6 is arranged between the first PPR pipe 11 and the second PPR pipe 4, and can record the accurate value of the discharge sucked into the negative pressure bottle 1 through the negative pressure.

Further, the liquid flow meter 6 is fixed on a short pipe 10 with both ends of a screw structure, the structure of which is shown in fig. 2, and the short pipe 10 is respectively in threaded connection with the first PPR pipe 11 and the second PPR pipe 4; one end of the second PPR pipe 4 is fixedly connected with a multi-caliber connector 7 for connecting a drainage pipe, and the caliber of the multi-caliber connector 7 is gradually reduced towards the direction far away from the second PPR pipe 4; the adjusting switch 5 comprises a rotating handle 51, a connecting shaft 53 and an elliptic iron sheet 54, the structure of the adjusting switch is shown in fig. 3, the length of the short axis of the elliptic iron sheet 54 is the same as the inner diameter of the first PPR pipe 11, a mark 52 is carved on the upper surface of the rotating handle 51, and the mark 52 and the elliptic iron sheet 54 are on the same plane; the negative pressure bottle 1 is made of rubber, and the side surface of the negative pressure bottle is in a corrugated shape.

Specifically, with continued reference to fig. 1, when the device is used, the drainage tube is connected to the multi-caliber connector 7, and the drainage tube is connected to the caliber matched with the drainage tube according to the caliber size of the drainage tube, so as to be sealed; next, the cap 9 is removed and the rotating handle 51 is rotated, so that the elliptical iron piece 54 is fixed in the first PPR tube 11 and closes the first PPR tube 11.
