Floor drain capable of rotatably cutting off hair and rotatable cutting method

Abstract

The invention discloses a floor drain capable of rotatably cutting off hair and a rotatable cutting method. The floor drain comprises a floor drain seat and a first cutting piece, wherein the first cutting piece is rotatably arranged around the axis in the floor drain seat, the floor drain further comprises screw blades and a rotating piece, the screw blades are arranged in the vertical direction, and are controlled to move downwards and reset upwards through a reset spring; the rotating piece is provided with a strip-shaped hole and matched with the first cutting piece; the screw blades penetrate through the strip-shaped hole of the rotating piece, the screw blades move up and down to drive the rotating piece to rotate along the preset first direction and second direction, and the first cutting piece rotates when the rotating piece rotates along the first direction and / or the second direction. The frictional force between the screw blades and the rotating piece is very small, the rotating piece is easily driven to rotate only by moving the screw blades up and down, so that the cutting function of the first cutting piece is realized, in addition, the operation saves labor, the installation is convenient, and the energy is saved.

Description

technical field [0001] The invention relates to a floor drain, in particular to a floor drain capable of rotatably cutting hair and a method for realizing rotary cutting thereof. Background technique [0002] The floor drain is an important interface connecting the drainage piping system with the indoor ground, and is one of the important components of the drainage system in the residence. Traditional floor drains tend to entangle hair, fabrics, etc., resulting in blockage of the floor drain, or hair that flows into the sewer through the traditional floor drain for a long time may also easily cause sewer blockage. For this reason, many floor drains with cutting functions have occurred in the prior art, which can be divided into two categories, one is electric, relying on commercial power or batteries or hydroelectric power to drive the motor to drive the cutting parts to rotate; the other is manual, mainly including There are two types, one is to rotate the cutting part wit...

AI Technical Summary

Problems solved by technology

However, the above-mentioned floor drains have the following disadvantages: the floor drains powered by commercial power or batteries have the problems of inconvenient installation and no energy saving; the floor drains relying on hydroelectric power generation are not effective in actual use; Unsmooth; the floor drain that relies on the screw to drive the rotation has a large contact area between the screw and the nut, resulting in very large friction between the two, and the nut and the cutting piece cannot be rotated at all in actual use.
