Spiral driving device and mop using same

Abstract

The invention relates to a spiral driving device and a mop using the same. The spiral driving device comprises an outer pipe, a sleeve, a guide screw block, a connecting rod and a driven piece, wherein two pairs of convex ribs are longitudinally arranged on the inner wall of the outer pipe, and a dovetail groove is formed between each pair of convex ribs; a dental plate with threads on one inner surface is inserted and clamped in each dovetail groove, and the sleeve is coaxially arranged at the top end of the outer pipe in a locking way; the guide screw block is clamped between the two dental plates, and the connecting pipe is axially inserted in the outer pipe; and the driven piece is fixedly arranged at the top end of the connecting rod, and is selectively driven by the guide screw block and rotates together with the connecting rod. In the invention, the spiral driving device with an automatic clutch function is utilized to drive the mop to rotate at high speed so as to achieve the dehydration object by centrifugal force generated by high-speed rotation; and the invention overcomes the defects that the usual self-rotating mop is easily damaged and the service life of a one-way bearing is short.

Description

technical field [0001] The invention relates to a spin mop, in particular to a screw driving device with a clutch function and a mop using the device. Background technique [0002] The mop is a necessary tool for cleaning the floor in almost every household. However, because the traditional mop must constantly clean the wiring harness and wring it out to clean a large area of ​​the floor, it is very inconvenient to use, and the user must clean the wiring harness every time. Bending over to accommodate buckets makes cleaning a rather tiring chore. Especially in winter, it is unbearable to require the user's hands to be in constant contact with icy water or cleaning fluid. Therefore, some operators adopt a rotating design for the head of the mop and then use centrifugal force to dry the moisture on the mop head, which can be called a novel and considerate design. However, the design of many commercially available mops with rotating heads is not very perfect, and there are st...

Problems solved by technology

However, one-way bearings can easily lose their transmission function due to water or sand

When the one-way bearing is wetted by water, if it does not rotate for a period of time, it is easy to get stuck due to rust; moreover, if the fine sand attached to the mop after mopping the floor enters the one-way bearing In the process, the one-way bearing will be worn out, the gap will be enlarged, and then the occlusal function will be lost and the transmission will not be possible.
