Embodiment Construction
[0008] according to figure 1 A telescopic dredging device for a sink is shown, comprising a telescopic bag 2 and a dredging rod 3, characterized in that: the telescopic bag 2 and the dredging rod 3 are connected to each other, and the telescopic bag 2 is connected to the handle 1 through a sealing plug 5, The bottom end of the dredging rod 3 is provided with a round hole 4 .
[0009] The flexible bag 2 is made of rubber material.
[0010] The dredging rod 3 is made of stainless steel.
[0011] The telescoping bag of the present invention can generate the effect of air pressure through compression, and transmit it to the pipeline to be dredged through the dredging rod. Through the effect of air pressure, the blocked garbage can be removed. If the garbage is seriously blocked, the dredged rod can be used to dredge it. Due to the negative air pressure after the expansion bag is compressed, when the compression rod is opened, the garbage can be sucked into the expansion bag, whi...
