  • Patent number: 10612230
    Abstract: A cable control device for a pipeline cleaner includes a barrel, a control member and a toggle. The pipeline cleaner includes a support tube and a cable accommodated in a cable drum. The barrel mounted at the front end of the support tube is provided with an adapter thereon. The barrel accommodates first and second rollers in a lower portion thereof. The control member rotationally accommodated in the adapter extends into the barrel and is provided with a third roller. The first, second and third rollers clamp the cable together. The toggle penetrating the adapter is coupled with the control member. In an operation to clean a jammed pipeline, the toggle is shifted along a circumference direction of the adapter for changes of spatial positions of the third roller relative to the first and second rollers and fast movement of the cable forward or backward controllably.

  • Patent number: 10189060
    Abstract: A cable feeding device for a drain cleaner includes an upper body mounted on a support tube of the drain cleaner, a control subassembly, and a lower body. The upper body in which an upper feeding roller is held and the lower body in which two lower feeding rollers are held join each other, so that a cable inside a cable drum of the drain cleaner can extend through a region encircled with the upper and lower feeding rollers and can be resisted by the upper and lower feeding rollers for controllable forward or backward movements of the cable into a drain to be cleaned. The lower body has at least one separate mold-stripping hole for easy manufacturing of the upper and lower bodies in a plastic injection molding process. The upper and lower feeding rollers are not exposed to the outside for longer service life to hold the cable.

  • Publication number: 20180126428
    Abstract: A pipe cleaning apparatus includes a storage drum, a hollow cylinder, a spring tube, an elastic brake, a grip, and at least one pad. The cylinder is provided with an outer slot and a clearance hole. The spring tube is held inside the storage drum and the cylinder. The elastic brake includes a fixed portion held in the outer slot and an actuating portion extending through the clearance hole and being movable between inside and outside of the cylinder. The grip can be axially moved relative to the cylinder for controlling movement of the actuating portion. The at least one pad is installed in the cylinder for positioning the spring tube. As such, a user moving the grip can control positions of the actuating portion to fix or release the spring tube.

  • Patent number: 9719237
    Abstract: A tool for removing hair from a drain includes an elongate pole, a grappler part, a barb unit, and a handle. The grappler part is provided at a front end of the elongate pole and includes a head end and a grappler protruding from a side of the elongate pole. The head end of the grappler part has a curved, arrowhead, or hooked end plane. The barb unit provided on the elongate pole is adjacent to the grappler part and includes a plurality of barbs aligned with the grappler of the grappler part at the same side of the elongate pole. The handle provided at a rear end of the elongate pole includes a pointer for indicating orientation of the barbs and the grapplers of the grappler part. The tool can be smoothly operated by a user for effective removal of congested hair from a drain.

  • Patent number: 9717215
    Abstract: A pet feeder includes an assembly base and a feeder body. The assembly base includes a base body having an annular external rim provided with a plurality of pluggable fins. The feeder body includes an annular surrounding wall and a feeding trough defined inside the surrounding wall. The surrounding wall of the feeder body is provided with several sets of slots arranged in a circumferential direction about a central axis thereof and annularly spaced from each other in the circumferential direction. Each of the several sets of slots extends a distinct depth and has a plurality of slots matching the pluggable fins of the assembly base. As such, a height of the feeding trough of the feeder body can be conveniently adjusted when one of the several sets of slots with a specific depth is coupled with the pluggable fins of the assembly base.
