The double action cleaning tool of the present invention includes a dynamic double action dual brush head and a handle. The dynamic double action dual brush head includes two brush heads rotatably attached to a brush head base, allowing the brush heads to independently rotate about the axis in which it is rotatably attached to the brush head base. A mechanical device capable of storing and releasing energy is connected between the two brush heads, which is rigidly attached to the brush head base. The double action cleaning tool stores energy in the form of potential energy in the mechanical energy storage device of the dynamic double action dual brush head during the sweeping stroke of the double action push broom. At the end of the sweeping stroke, the stored potential energy is converted into kinetic energy and rotates the dual brush, thereby providing an additional sweeping motion.

The present disclosure discloses a circulating water pump for a data center computer room, including a circulating water pump main body. A water inlet pipe and a water outlet pipe are respectively arranged on a left side and a right side below the circulating water pump main body. An end of the water inlet pipe is fixedly connected to a connecting pipe, on which there is provided with a cleaning pipe component I and a cleaning pipe component II having a same structure, and an electric butterfly valve is fixedly installed at an end of the cleaning pipe component I and of the cleaning pipe component II away from the water inlet pipe.

An outdoor cleaning device configured to clean outdoor surfaces using a variety of fluids and techniques. The outdoor cleaning device includes a brush head, a motor and a transmission for providing a driving force to the brush head, a fluid tank for storing a fluid (e.g., a cleaning solution or detergent), and a controller for controlling mixing (or not mixing) the fluid stored in the fluid tank during operation of the outdoor cleaning device. The controller may enable fluid from the cleaning tank to be mixed with a second fluid (e.g., water) prior to being dispensed via at least one nozzle. The at least one nozzle may be secured to a guard cover via grooves on an inner guard cover and an outer guard cover. The nozzle(s) enables the distribution of cleaning fluids in various directions, enhancing the brush head's cleaning capability.

A pool cleaning assembly kit includes a utility connector, a handle base and one or more utility tool. The utility connector includes a connecting dock and two end connectors integrally provided at two ends of the connecting dock respectively. The handle base includes a handle frame detachably connected to the utility connector and configured to be detachably connected with a handle. The one or more utility tool is configured to be detachably connected to at least one of the end connectors so as to integrally assemble with the utility connector to form a cleaning tool.

A back-washing device is provided. The device is comprised of a waterproof body equipped with a circular, spinning brush powered by a motor and capable of dispensing cleaning liquids such as soap or shampoo from an integrated reservoir through a system of tubing and a pump. The device can be securely attached to a shower wall using various fasteners including suction cups, adhesives, or magnets. The device features a rechargeable battery that powers both the brush's motor and the liquid dispensing pump, and it includes a user interface with buttons for controlling the brush's rotation speed and activating the liquid dispensing function.

A cleaning module includes: a first rolling brush including first brushes; and a second rolling brush arranged substantially side by side with the first rolling brush and including second brushes, wherein when the first rolling brush and the second rolling brush rotate, a first outer contour formed by a trajectory of outer ends of the first brushes and a second outer contour formed by a trajectory of outer ends of the second brushes at least partially interfere with each other, and the first brushes are not in contact with the second brushes.

A handheld electric cleaning brush with two nested brush heads rotating oppositely, comprising: a cylindrical shell and brush heads, wherein the brush heads are arranged at a front end of the cylindrical shell, and a handle is arranged on a side wall of the cylindrical shell. The brush heads comprise an inner brush head and an outer brush head. Two nested rotating shafts are arranged in the cylindrical shell, the two brush heads are nested spaced apart from each other and are replaceably snap-fitted into front ends of the two nested rotating shafts, respectively, and the two nested rotating shafts are an inner rotating shaft and an outer rotating shaft, respectively. One driving device drives the two rotating shafts to rotate oppositely so as to drive the two brush heads to rotate oppositely. The inner rotating shaft is sleeved on a central shaft arranged in the cylindrical shell. A cleaning agent channel is provided in the central shaft, and a cleaning agent fed from a cleaning agent tank is pumped into the cleaning agent channel by means of a liquid transfer pump, and is fed into the inner brush head from a front end of the central shaft.

The present invention relates to an assembly with a novel design of dual head open and close option toothbrush. The assembly is battery operated, easy to use, provides better output, and is easy to use.

A pool cleaning tool includes a main frame and bristles extending therefrom, wherein the main frame has at least a locking pin hole; at least a side brush comprising a side brush frame and bristles extending therefrom, wherein the side brush frame has a through hole; a locking element comprising a head and a pin shaft connected therewith, wherein the size of the end of the pin shaft far from the head is larger than the through hole, the pin shaft is made of elastic material, such that the pin shaft can pass through the locking pin hole and the through hole to detachably connect the main brush with the at least one side brush. The present disclosure can achieve the purpose of enhancing the stability of the connection between the side brush and the main brush.

The present disclosure provides a dust box including a first chamber including a waste inlet; a second chamber including an air outlet; and a transition channel.
