Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

Referring to fig. 1 to 3, the present utility model provides a technical solution: the utility model provides a negative pressure formula drainage tube, including body 1, body 1 position hose, the inner wall of body 1 is provided with the anti-blocking edge 11 of distributing along axial direction, anti-blocking edge 11 plays the effect of preventing body 1 flattening jam, the oral area of body 1 is provided with shutoff shell 2, the through-hole 21 has been seted up to this shutoff shell 2, during the negative pressure suction, liquid can be introduced into in the body 1 through the through-hole 21, rubber expansion joint 3 and the valve 4 that is located rubber expansion joint 3 low reaches side have been concatenated on the body 1, rubber expansion joint 3 plays the effect of clear jam, when the through-hole 21 blocks up, close valve 4, then manual pressure rubber expansion joint 3, outwards jet through the through-hole 21 in the body 1 this moment, with the jam blowout in the through-hole 21, combine this body 1 to have the effect of preventing flattening jam and foreign matter jam.

In this embodiment, the number of the anti-blocking ribs 11 is three and the anti-blocking ribs 11 are uniformly distributed in the circumferential direction relative to the pipe body 1, wherein the cross section of the anti-blocking ribs 11 is circular arc, and after the pipe body 1 is flattened by the three anti-blocking ribs 11, three uniform through-flow gaps are formed in the pipe body 1, so that the anti-blocking advantage is further improved.
