Abstract
Description
- The present invention relates to an electric dredger for removing obstructions clogged in pipes such as toilet pipes, sink pipes and drain pipes.
- The conventional dredgers are manually operated to rotate within the clogged pipes so as to remove the clogged hairs and other objects in the pipe. However, it takes time and has to operate it with a lot of force. The conventional dredgers usually assembled by way of welding or threading, the parts may be loosened or separated from each other. The conventional dredgers need to be improved.
- The present invention intends to provide an electric dredger to eliminate the shortcomings mentioned above.
- The present invention relates to an electric dredger and comprises a shaft rod and a helical reeling piece. The shaft rod has a shaft sleeve connected to the first end thereof. The shaft sleeve is made of micro-soft iron and has a central shaft hole defined in the distal end thereof. The helical reeling piece has its first end connected to the central shaft hole of the shaft sleeve. The external end surface of the shaft sleeve has two V-shaped and spaced inclined surfaces. When assembling, the helical reeling piece has its first end inserted into the central shaft hole of the shaft sleeve, and the shaft sleeve is pressed externally and deformed to secure the helical reeling piece in the central shaft hole of the shaft sleeve. The shaft rod has a connecting rod connected to the second end thereof, and the connecting rod is connected to and driven by an electric drilling tool. The helical reeling piece is made by helically wound flexible metal wire so as to form a hollow piece. The second end of the helical reeling piece has an operation end connected thereto. The operation end cleans obstructions in a pipe. The helical reeling piece is connected to the shaft rod by way of pressing which improves the shortcomings of welding and threading.
- The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

-
Fig. 1 is a perspective view to show the electric dredger of the present invention; -
Fig. 2 is a cross sectional view to show the helical reeling piece is to be connected to the central shaft hole of the shaft sleeve; -
Fig. 3 is a cross sectional view to show that the helical reeling piece is inserted into the central shaft hole of the shaft sleeve, and the shaft sleeve is to be pressed to secure the helical reeling piece, and -
Fig. 4 is a cross sectional view to show that the helical reeling piece secure in the shaft sleeve after the shaft sleeve is pressed. - Referring to
Figs. 1 and4 , the electric dredger of the present invention comprises ashaft rod 10 and ahelical reeling piece 20. Theshaft rod 10 has ashaft sleeve 11 connected to the first end thereof. Theshaft sleeve 11 is made of micro-soft iron which is deformed when external pressure is applied thereto. Acentral shaft hole 12 is defined in the distal end of theshaft sleeve 11, and thehelical reeling piece 20 has the first end thereof connected to thecentral shaft hole 12 of theshaft sleeve 11. The external end surface of theshaft sleeve 11 has two V-shaped spacedinclined surfaces 13 which prevent theshaft sleeve 11 being broken when being pressed. Theshaft rod 10 has a connectingrod 14 connected to the second end thereof. The connectingrod 14 is to be connected to and driven by an electric drilling tool which rotates theshaft rod 10. Theshaft rod 10 includes a throughhole 15 defied radially therethrough. Apin 16 extends through the throughhole 15 and is connected with aclip 17. Thehelical reeling piece 20 is removably connected with theclip 17 to reduce the space occupied by thehelical reeling piece 20. - The
helical reeling piece 20 is made by helically wound flexible metal wire so as to form a hollow piece. The first end of thehelical reeling piece 20 is connected to thecentral shaft hole 12 of theshaft sleeve 11, and the second end of thehelical reeling piece 20 has anoperation end 21 connected thereto. Theoperation end 21 is a helical end and used to clean obstructions in a pipe. - When assembling, as shown in
Figs. 2 ,3 and4 , the first end of thehelical reeling piece 20 is inserted into the central shaft hole12 of theshaft sleeve 11, and theshaft sleeve 11 is pressed externally to deform theshaft sleeve 11 to secure thehelical reeling piece 20 in the central shaft hole12. - While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
