Description

Technical Field

[0001] The invention relates to the technical field of cleaning brushes, and in particular to an electric rotating cleaning brush device. Background Art

[0002] An electric cleaning brush is a tool that uses electricity to drive the brush head to rotate or vibrate, thereby increasing the cleaning effect. It drives the brush head through a motor, converting the back and forth wiping action during manual cleaning into a more efficient mechanical movement. This mechanical movement can remove stains, save manpower, and can reach into gaps and corners that are difficult to clean manually.

[0003] A cleaning brush is used to clean the surface of an object. When using an electric cleaning brush to clean the surface of a car wheel hub, in order to achieve a cleaning effect, a cleaning agent is often sprayed on the surface of the wheel hub, and then the cleaning brush is used to clean it. This cleaning method requires spraying the wheel hub with a cleaning agent in advance, and then using a cleaning brush to clean it, which takes a lot of time. During long-term use, the motor is severely heated, and the cleaning agent is generally sprayed at room temperature. The cleaning agent has low activity and poor solubility.

An exhaust port 24 is provided, a mounting seat 29 is fixed inside the housing 21, the mounting seat 29 is fixedly connected to the motor 25, and the motor 25 is connected to a power line 101 extending outside the handle 1; when working, the motor 25 channel works to drive the worm 26 to rotate, drives the bevel gear 27 to rotate, drives the rotating sleeve 23 to rotate, realizes the rotation of the brush body 8, and utilizes the friction between the brush body 8 and the object to clean the object (wheel hub), and during the rotation of the bevel gear 27, drives the fan blade 28 to rotate, stirs the airflow inside the housing, and makes some heat generated by the motor 25 blown out from the exhaust port 24 to exchange with the outside world for heat dissipation;

The pipe sleeve 33 is connected with a hollow ball 32. The upper end of the hollow ball 32 is fixed with a liquid spraying pipe 31 in a V-shaped structure. The upper end of the liquid spraying pipe 31 is arranged horizontally with the brush body 8. When working, refer to Figure 5 The cleaning agent flows from the left end of the spiral long tube 35 to the right in a spiral path, taking away some heat generated by the operation of the motor 25, and the cleaning agent absorbs heat to heat up and then flows into the liquid inlet pipe 34, and then enters the pipe sleeve 33 and the hollow ball 32, and finally sprays onto the surface of the object from the end of the liquid spray pipe 31, dissolving pollutants such as oil and dust on the surface of the object, and cooperates with the rotating brush body 8 to clean the surface of the object synchronously.

[0033] The other end of the spiral long tube 35 is connected to a liquid delivery mechanism 4, which is installed inside the housing 21;

[0034] The pipe sleeve 33 is installed with a valve assembly 7;

[0035] The valve assembly 7 is connected to the start-stop assembly 6 , and the start-stop assembly 6 is connected to the rotating sleeve 23 .

[0036] In this embodiment, a cleaning agent storage and delivery method is provided. Figure 1 , Figure 5The liquid delivery mechanism 4 includes a liquid storage tank 44 and a liquid storage chamber 45 on the right side. The liquid storage tank 44 is fixed inside the left end of the casing 21. The diameter of the liquid storage tank 44 is smaller than the inner diameter of the casing 21. A piston plate 46 is horizontally slidably connected inside the liquid storage tank 44. The end of the spiral long tube 35 is fixedly connected to the right end of the liquid storage tank 44 and extends into the liquid storage chamber 45. An air pipe 43 extending out of the casing 21 is fixed inside the left end of the liquid storage tank 44. A liquid infusion pipe 42 extending out of the casing 21 is fixed to the upper right end of the liquid storage tank 44. The end is threadedly connected with a sealing cover 41; when working, the detergent (neutral detergent) is replenished into the liquid storage chamber 45 from the liquid replenishing tube 42, the sealing cover 41 is closed, and one end of the air pipe 43 is connected to an air pump, and the gas is input into the left end of the liquid storage tank 44, and pressure is applied to the left side of the piston to move the piston to the right to pressurize the detergent in the liquid storage chamber 45, squeeze the detergent into the spiral long tube 35, make the detergent flow in the spiral long tube 35, and finally be sprayed out from the liquid spraying tube 31, taking away the heat around the motor 25 and heating the detergent to increase its activity.

[0037] Specifically, a valve is provided at the lower end of the hollow ball 32 to control the opening and closing of the hollow ball 32. The valve assembly 7 includes a connecting pipe 72, which is fixed at the lower end of the hollow ball 32 and extends into the interior of the pipe sleeve 33. The connecting pipe 72 penetrates a liquid inlet 74 with a square structure. The lower end of the pipe sleeve 33 is rotatably connected to a rotating rod 71, and a valve plate 73 with a rectangular structure is fixed to the upper end of the rotating rod 71. The valve plate 73 is attached to the lower end of the liquid inlet 74. When working, when the valve plate 73 coincides with the bottom end of the liquid inlet 74 (see Figure 6 ), the connecting pipe 72 is closed, and the cleaning agent entering the pipe sleeve 33 will not be transported to the hollow ball 32, and the cleaning agent will not be sprayed out from the spray pipe 31. When the rotating rod 71 rotates and drives the valve plate 73 to rotate (see Figure 7 ), the bottom end of the liquid inlet 74 is no longer blocked, the detergent is pressurized and sent into the hollow ball 32 from the liquid inlet 74, and then sprayed out from the end of the liquid spray pipe 31, so that the spraying of the detergent is controlled by the rotation of the valve plate 73.

[0038] Embodiment 2

[0039] In this embodiment, a method for controlling the rotation of the valve plate 73 is provided. Figure 2 , Figure 4 , Figure 6The start-stop assembly 6 includes a rotating plate 61, which is fixed to the bottom end of the rotating rod 71. A torsion spring 64 is connected between the rotating plate 61 and the bottom end of the pipe sleeve 33. A fixing ring 62 is fixed to the outer surface of the rotating sleeve 23. Four V-shaped levers 63 are fixed to the outside of the fixing ring 62. The end of the rotating plate 61 close to the lever 63 is wedge-shaped. A limiting rod 69 is fixed to the upper surface of the rotating plate 61. The top of the limiting rod 69 is slidably arranged with the lower end of the pipe sleeve 33. When working, when the rotating sleeve 23 is driven by the motor 25 to rotate and drive the brush body 8 to rotate, the fixing ring 62 is driven to rotate, so that the lever 63 rotates. When the end of the lever 63 rotates and aligns with the rotating plate 61 When the wedge-shaped surfaces at the ends come into contact, the rotating plate 61 is pushed to rotate, thereby driving the rotating rod 71 and the valve plate 73 to rotate, causing the torsion spring 64 to generate elastic force to open the liquid inlet 74. When the lever 63 rotates and disengages from the rotating plate 61, the torsion spring 64 drives the rotating rod 71 and the valve plate 73 to rotate and reset, blocking the liquid inlet 74. Therefore, during the rotation of the brush body 8, the valve plate 73 rotates intermittently, and the liquid inlet 74 is opened intermittently, so that the detergent flows into the spray pipe 31 and then sprays out, so that the detergent takes away the heat around the motor 25 to heat up and then sprays out intermittently onto the surface of the object for cleaning, thereby avoiding waste of detergent and allowing the detergent to absorb more heat to cool down the motor 25.

[0040] Embodiment 3

[0041] In this embodiment, in order to realize the swinging of the spray pipe 31 to adjust the spray angle of the detergent, refer to Figure 4 , Figure 5 The start-stop assembly 6 also includes a support frame 68, an L-shaped fixed frame fixed to the outer wall of the pipe sleeve 33, and a roller 67 is rotatably connected to the bottom end of the fixed frame, and the roller 67 is rollingly connected to the outer surface of the fixed ring 62. One end of the roller 67 is rotatably connected to a connecting rod 66, and the upper end of the connecting rod 66 is ball-connected with a rocker 65, and one end of the rocker 65 is fixedly connected to the outer surface of the hollow ball 32; when working, the fixed ring 62 is driven to rotate by the rotating sleeve 23. Under the action of friction, the roller 67 is also driven to rotate together, driving the connecting rod 66 to move, so that the rocker 65 ball-connected with the connecting rod 66 moves, and the hollow ball 32 is pushed to swing in an irregular small range at the upper end of the pipe sleeve 33, driving the spray pipe 31 to swing together, and adjusting the spray direction of the spray pipe 31. When the brush body 8 cleans the object, the detergent intermittently sprayed from the spray pipe 31 is sprayed to other positions on the surface of the object to dissolve the pollutants in advance, and then cooperates with the brush body 8 to clean the object, with a wide spray range and good cleaning effect.

[0042] See also Figure 1In order to facilitate personnel to hold the drilling rig, a rocker mechanism 5 is installed on the casing 21, and the rocker mechanism 5 includes a positioning ring 51. The bottom positioning ring 51 is provided with a plurality of annularly distributed sockets 52. The positioning ring 51 is rotatably connected to the outer surface of the right end of the casing 21. A rocker arm 54 is fixed to the outer wall of the positioning ring 51. An anti-slip sleeve 55 is fixed to the end of the rocker arm 54. The rocker arm 54 is slidably connected to a limit pin 53 in a J-shaped structure, and one end of the limit pin 53 is slidably inserted into the socket 52. Personnel can hold the handle 1 with one hand and the rocker arm 54 with the other hand, hold the drilling rig body, clean objects, adjust the position of the rocker arm 54 by rotating the rocker arm 54 and the positioning ring 51, hold the rocker arm 54 and the handle 1 according to needs, and then insert the limit pin 53 into the socket 52 to position the rocker arm 54.

[0043] Working principle: A person holds the handle 1 and powers on the motor 25 to drive the brush body 8 to rotate and clean the surface of the wheel hub. During the cleaning process, the internal ventilation and pressurization of the liquid storage tank 44 causes the piston to move to pressurize the detergent inside the liquid storage chamber 45. The pressurized detergent flows into the spiral long tube 35 to take away the heat around the motor 25 for cooling, and heats up the detergent and enters the hollow ball 32, and then is sprayed from the liquid spray pipe 31 to the surface of the wheel hub, dissolving pollutants such as oil on the outer surface of the wheel hub, and cooperating with the brush body 8 to clean the wheel hub. During the cleaning process, the rotating sleeve 23 rotates to drive the brush body 8 to rotate, and drives the fixed ring 62 to rotate, so that the lever 63 rotates. When the end of the lever 63 rotates and contacts the wedge-shaped surface at the end of the rotating plate 61, the rotating plate 61 is pushed to rotate, thereby driving the rotating rod 71 and the valve plate 73 to rotate, so that the torsion spring 64 generates elastic force to open the liquid inlet 74. When the lever 63 rotates and disengages from the rotating plate 61, the torsion spring 6 4, the rotating rod 71 and the valve plate 73 are driven to rotate and reset, blocking the liquid inlet 74, so that during the rotation of the brush body 8, the valve plate 73 is intermittently rotated, the liquid inlet 74 is intermittently opened, the detergent flows into the liquid spraying pipe 31 and then sprays out, so that the detergent takes away the heat around the motor 25 and heats up, and then is intermittently sprayed onto the surface of the object for cleaning, thereby avoiding the waste of detergent and allowing the detergent to absorb more heat to cool the motor 25. In addition, during the rotation of the fixing ring 62, the roller 67 is driven to rotate together, the connecting rod 66 is driven to move, the rocker 65 ball-connected with the connecting rod 66 is moved, and the hollow ball 32 is pushed to swing irregularly in a small range at the upper end of the pipe sleeve 33, driving the liquid spraying pipe 31 to swing together, and adjusting the spraying direction of the liquid spraying pipe 31. When the brush body 8 cleans the object, the detergent intermittently sprayed from the liquid spraying pipe 31 is sprayed to other positions on the surface of the object to dissolve pollutants in advance, and then cooperates with the brush body 8 to clean the object.
