Abstract

<P>PROBLEM TO BE SOLVED: To provide a gear type low water pressure rotation mechanism utilizing the low water pressure of water works for general households or the like and capable of coping with cold water and high temperature water without using a boosting device or the like. <P>SOLUTION: A gear A(6) is engaged with a gear B(7) in a casing 1, and aqueduct pressure water is poured in directly without using the boosting device or the like to the lowly pressurized water or hot water or the like of water works from the outside. The gears are rotated to rotate a cleaning device such as a brush attached to the rotary shaft, water or hot water are poured simultaneously, a rotation speed and torque are adjusted to be suitable for a purpose, and the work of washing cleaning or the like is performed. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

This is a gear-type low water pressure rotation mechanism that can handle cold water, room temperature water, and high temperature water without using a pressure booster etc., using general household waterworks.

  General cleaning machines are limited to those using electric motors.

When electricity is used, electrical hazards such as electric leakage are a problem, and special attention is required for the elderly, women, and the disabled.

When the force is excessive, physical danger is a problem, and special attention is required for the elderly, women, and the disabled.

Using general household water supply, without using a pressure booster etc., apply water pressure of cold water, room temperature water, high temperature water to the two gears housed in the casing, rotate the gears and attach them to it Rotate a cleaning tool such as a brush and sprinkle the drainage at the same time to make a rotary washing machine.

It is a small and lightweight high torque generator that can easily control operation, stop, rotational force, rotational speed, and the like.

There is no electrical danger such as electric leakage because household water supply is used.

Since a low water pressure power source such as a domestic water supply is used, it does not generate excessive force, so it has excellent safety.

Since the power source (water supply) in the home is used, the power source can be easily obtained.

Because it can be made small and light, it is easy to operate and can be used by elderly people, women, or disabled persons.

If there is a domestic water supply, it can be used both indoors and outdoors, without a pressure booster, and is easy to carry.

Simply put this device on the target part, and then the brush will rotate if water or warm water is passed through. At the same time, the waste water can be easily washed with water.

Installation and removal can be done easily using parts such as commercially available one-touch joints.

In the experiment, it was possible to obtain a torque of 2 N · m in a gear having an outer diameter of 0.068 m and a width of 0.028 m. It is safe and sufficient as a washing brush.

It can be used for various purposes if it is changed to a convenient type according to the purpose. (Example: Body washing Car wash Deck brush Floor, wall, window cleaning Body massage, etc.)

Cross section Longitudinal section 1 Longitudinal section 2

In FIG. 1, two gears A (6) and B (7) can rotate in a state where they are engaged with each other in the casing.

A long A-axis (8) and a B-axis (9) are attached to both the AB gears and come out to the outside, and a cleaning tool such as a brush is attached to the end of the axis.

When tap water is injected from the pressure inlet, the pressure in the pressure receiving chamber increases and both gears AB rotate in the direction of the arrow.

The injected water or hot water moves to the drainage chamber on the opposite side by the rotation of the gear.

If the water is discharged from the drainage chamber to the outside, particularly to the brush side, water washing is advantageous.

One brush may be used, but if two brushes are attached, the force (reaction force) for turning the main body is eliminated, and control with one hand is facilitated, and the cleaning area is increased.

The rotational speed and rotational force can be easily adjusted by adjusting the amount of water injected.

Claims (7)

A gear-type low water pressure rotation mechanism that generates a high rotational force that can be used in a wide range of cold water, room temperature water, and high temperature water using a low water pressure source such as a domestic water supply, without using a pressure intensifier. 2. The gear-type low water pressure rotation mechanism according to claim 1, wherein in order to obtain a high rotational force even at a low pressure, the clearance between the meshing teeth and the clearance between the sliding surfaces of each part are minimized to reduce the pressure relief. 2. The gear type low water pressure rotating mechanism according to claim 1, wherein the bearing portion uses a rolling bearing having a small frictional resistance, such as a ball bearing or a roller bearing, because frictional resistance is generated due to water pressure. The gear-type low water pressure rotating mechanism according to claim 1, wherein one side of the shaft is exposed to the outside and a brush or other cleaning tool is attached and rotated to form a cleaning machine. The brushes attached to the two rotary shafts A and B can counteract the reaction rotational force of the main body, increase the work area, improve operability even with one hand, and achieve stability. Gear type low water pressure rotation mechanism The gear-type low water pressure rotating mechanism according to claim 3 or 4, wherein water or warm water is poured into the brush to form a washing rotary brush cleaner.   The gear-type low water pressure rotating mechanism according to claim 1, wherein the flow rate is adjusted by an adjusting valve (19) so that the rotational force and rotational speed can be easily controlled.
