Description

Cleaning brush head for dredging toilet

Technical Field

The utility model belongs to the technical field of cleaning tools for dredging sanitary wares, and particularly relates to a cleaning brush head for dredging a sanitary wares by reverse water bending.

Background

In order to increase the trafficability of the reverse water bend of the conventional cleaning and dredging tool for the reverse water bend of the sanitary appliance, a spring is generally used as a power transmission tool for dredging a pipeline, and when the cleaning and dredging tool for the reverse water bend of the sanitary appliance works, the cleaning and dredging tool for the reverse water bend can not bear higher torsion and rotating speed although the cleaning and dredging tool can pass through the reverse water bend, and particularly when a certain pushing force is required to break a blockage, the spring can be bent under the condition of resistance, so that the impact force can not act on the blockage. Sometimes, steel wires with thicker wire diameters are used for manufacturing the dredging spring for increasing the rigidity of the spring, but the practical result is that the rigidity and the rigidity of the dredging spring are improved, but the trafficability of the dredging spring in reverse water bending is weakened.

In addition, there are long-handled electric brushes on the market, which are specially used for cleaning toilets, one end of the long handle is connected with the motor, and the other end is connected with the brush head. When in operation, the motor is started to drive the brush head to rotate at high speed to clean the surfaces of sanitary appliances such as a toilet. Because the long handle is generally made of plastic or aluminum alloy materials, the long handle cannot be bent to clean the reverse water bend and the rear auxiliary pipeline through the reverse water bend, and actual observation shows that the bottom of the reverse water bend is a main part where alkali scale deposition is blocked, and timely cleaning can effectively avoid the deposition of alkali scale in the reverse water bend, so that the blocking is delayed.

Disclosure of Invention

The utility model aims to provide a cleaning brush head for dredging a sanitary appliance by reverse water bending, so as to solve the problems in the background technology.

The design of the cleaning brush head for the reverse water bend of the sanitary appliance aims at seeking balance between hardness required for transmitting the dredging impact force and flexibility required for the reverse water bend of the sanitary appliance, so that the brush head can pass through the reverse water bend and effectively clean dredging plugs. The dredging and cleaning brush head adopts the design of a conical power transmission shaft, so that the cleaning end is thinner, has good flexibility and larger bending radius, and is convenient for bending and passing through reverse water bending; the power end is thicker, has good hardness and rigidity, is not easy to bend and deform, can effectively transfer motor torsion and thrust to the cleaning end, and provides physical support for more efficient work of the cleaning brush head.

Secondly, the adoption of the metal inner core aims at transmitting the torque of the driving motor to the cleaning component of the cleaning end without delay and with maximum efficiency: cleaning brush heads or cleaning knocking chains. In particular, when the striking chain is cleaned, the striking chain rotates at a high speed after the torque transmitted by the metal shaft is obtained, the cleaning chain can be unfolded to form a sphere rotating at a high speed, a high spin angular momentum is generated, when the striking chain encounters a reverse water bend and deposits in the reverse water bend, compared with a spring rotating at a low speed of the traditional equipment, the striking chain is more difficult to change a movement track due to the influence of resistance generated by the reverse water bend and the deposits in the reverse water bend, so that the striking chain is more stable and is easier to convert the impact force transmitted by the power end to break through blockage.

In the design, the hand-held protection tube is arranged on the conical power shaft, and the purpose of the hand-held protection tube is to provide support and limit for the conical power shaft.

Two sliding bearings are respectively arranged at the outlets of the two sides of the inner part of the hand-held protective tube, and the purpose is that: when the power shaft rotates, the sliding friction force generated between the power shaft and the hand holding protection tube is reduced as much as possible, and the working efficiency of the motor is ensured. A reset pressure spring is arranged between the two sliding bearings and is in a compressed state to isolate the two sliding bearings; the two sliding bearings are separated to the limiting blocking position of the protective tube in opposite directions under the action of the elastic force of the springs. The reset spring is provided with the aim of: the two sliding bearings are limited at two ends of the hand-held protective tube, two supporting points can be formed in the protective tube in actual operation, the conical power shaft is supported, and friction between the conical power shaft and the protective tube is reduced. The inner diameter of the sliding bearing is not smaller than the maximum cross-section diameter of the conical shaft, and the aim is to reduce friction with the protective tube as much as possible.

One side of the cleaning end of the conical power shaft is provided with a brush head or a knocking chain, and the brush head or the knocking chain can be exchanged according to actual use requirements. The brush head or the cleaning knocking chain is fixed on the metal inner core of the conical shaft through a jackscrew. The conical power shaft rotates to drive the brush head or the cleaning knocking chain to rotate at high speed, and bristles on the brush head can be used for cleaning slight attachments on the surface of the sanitary appliance; the cleaning knocking chain can be used for cleaning stubborn sediment in the reverse water bend of the sanitary appliance. The knocking chain is rotated and unfolded to form a sphere, the sphere is swept across the inner wall of the reverse water bend, and stubborn sediments attached to the inner wall are knocked down and removed layer by layer.
