The technical scheme for solving the technical problems is as follows:

a sprinkler head with a flow stopping function comprises a sprinkler head column head, a sprinkler head column body, a sprinkler head column tail, a damping spring and a check ball, wherein the sprinkler head column head is installed at the front end of the sprinkler head column body, the rear part of the sprinkler head column body is connected with the front part of the sprinkler head column tail, spray pipes communicated with each other are arranged in the sprinkler head column body and the sprinkler head column tail, the front end of the spray pipe of the sprinkler head column body is connected with the sprinkler head column head, a flow stopping cavity is arranged at the rear part of the spray pipe of the sprinkler head column body, the diameter of the flow stopping cavity is larger than that of the spray pipe, the damping spring and the check ball are arranged in the flow stopping cavity, the front end of the damping spring is propped at the connecting step of the flow stopping cavity and the spray pipe, the front end of the check ball is propped at the rear end of.

Above-mentioned sprinkler head with function of only flowing, the rear portion of shower nozzle cylinder and shower nozzle post tail front portion are relative cascaded sleeve structure respectively, and cascaded sleeve adopts threaded connection, and O type circle is installed to cascaded sleeve department.

According to the sprinkler head with the flow stopping function, the fixing nut is arranged on the sprinkler head column body, and the sprinkler head is fixed on the support through threaded connection by the fixing nut.

The utility model has the advantages that:

the damping spring and the check ball are arranged in the sprinkler head, when the main pipeline has water pressure, the water pressure pushes the check ball forwards, a gap is formed between the water spray pipe at the tail of the sprinkler head column and the check ball, and water flow enters the sprinkler head column body and is sprayed out from the sprinkler head column head; after the main pipeline is closed, the check ball retreats under the pressure of the damping spring to plug the spray pipes at the tail of the spray head column, and stored water in the spray pipes cannot flow out of the spray heads.

The utility model discloses simple structure, convenient to use have the function that the individual item only flowed, can pass through the rivers when the main line is opened, and close back self-sealing at the main line, prevent that the surplus water in the pipeline from passing through the shower nozzle and flowing, have realized the automatic only flow of watering shower nozzle, have practiced thrift the water resource, have avoided polluted environment and damaged equipment.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a schematic view of the water spraying state of the present invention.

The figures are labeled as follows: the nozzle comprises a nozzle column head 1, a nozzle column body 2, a nozzle column tail 3, a fixing nut 4, an O-shaped ring 5, a spray pipe 6, a flow stopping cavity 7, a damping spring 8 and a check ball 9.

Detailed Description

The utility model discloses constitute by shower nozzle column cap 1, shower nozzle cylinder 2, shower nozzle column tail 3, fixation nut 4, O type circle 5, damping spring 8, check ball 9.

The figure shows that the nozzle post head 1 is installed at the front end of the nozzle post body 2, and the rear part of the nozzle post body 2 is connected with the front part of the nozzle post tail 3. The spray head column body 2 and the spray head column tail 3 are respectively cylinders, the rear part of the spray head column body 2 and the front part of the spray head column tail 3 are of opposite stepped sleeve structures, the stepped sleeves are in threaded connection, and O-shaped rings 5 are installed at the stepped sleeves for sealing.

The figure shows that the nozzle column body 2 is provided with a fixing nut 4, and the fixing nut 4 fixes the nozzle on the bracket through threaded connection, so that the nozzle is convenient to disassemble.
