Description

Technical Field

[0001] The utility model relates to the technical field of roller brushes, in particular to a multifunctional paint roller brush. Background Art

[0002] A paint roller brush is a tool for applying paint or coating. Most of its materials are engineering plastics and fibers, and some are made of natural wool fabrics. When a large area of coating is required for interior decoration in daily construction projects, a roller brush is usually used. Usually, a handle rod is also assembled on the roller brush for the convenience of workers.

[0003] During the process of using the roller brush to roll-brush the wall, it is necessary to immerse the roller brush into the paint bucket to make the roller brush fully covered with paint, and then paint the wall. Since the amount of paint that the roller brush can hold is limited, this method requires the staff to continuously immerse the roller brush into the paint bucket, but continuously waving the entire roller brush consumes a large amount of physical strength of the staff, and painting the wall is also more troublesome. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that the amount of paint that the roller brush can hold is limited, and it is necessary for the staff to continuously immerse the roller brush into the paint bucket, which is more troublesome.

[0005] To solve the above technical problem, the technical solution provided by the utility model is: a multifunctional paint roller brush, including a U-shaped bracket, a roller brush is rotatably arranged in the U-shaped bracket, connecting rods are arranged on both sides of the U-shaped bracket, and a hand-held cylinder is arranged between the lower parts of the connecting rods. It is characterized in that: a cavity and a placement groove are sequentially arranged in the hand-held cylinder from top to bottom, a paint replenishing mechanism is arranged in the cavity, the paint replenishing mechanism includes a micro electric push rod, a piston block located below the micro electric push rod, and a spring sleeved on the micro electric push rod. The micro electric push rod is located above the hand-held cylinder, the telescopic rod body of the micro electric push rod is located in the hand-held cylinder, the piston block is located in the cavity, and the two ends of the spring are respectively connected with the inner top surface of the cavity and the piston block.

[0006] As a further scheme of the utility model, two pipes are communicated and arranged below the cavity, a circulation cavity is arranged in the U-shaped bracket, a connecting pipe communicated with the circulation cavity is arranged below the U-shaped bracket, and a plurality of nozzles communicated with the circulation cavity are arranged above the U-shaped bracket.

[0007] As a further scheme of the utility model, a corrugated telescopic pipe one and a corrugated telescopic pipe two are respectively communicated and arranged on the pipes, the other end of the corrugated telescopic pipe two is communicated with the connecting pipe, and the other end of the corrugated telescopic pipe one is communicated with the paint bucket.

[0008] As a further scheme of the utility model, check valves are respectively arranged on the pipes, and the flow directions of the check valves are opposite.

[0009] As a further solution of the utility model, there are at least five nozzles.

[0010] The advantage of the utility model over the prior art is that by setting up a paint touch-up mechanism, the staff only needs to control the micro-electric push rod to start, drive the piston block to squeeze the paint out of the cavity, and then send it to the nozzle through the corrugated telescopic tube 2 and spray it onto the roller brush barrel. The staff does not need to constantly wave the entire roller brush barrel to immerse it in the paint bucket to touch up the paint, thereby reducing the labor intensity of the staff.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0018] Combined with the attached Figure 1 、 Figure 2 A multi-functional paint roller brush, including a U-shaped bracket 1, a roller brush 2 is rotatably arranged inside the U-shaped bracket 1, connecting rods 3 are arranged on both sides of the U-shaped bracket 1, and a hand-held cylinder 4 is arranged between the lower surfaces of the connecting rods 3. It is characterized in that: a cavity 5 and a placement groove 6 are sequentially arranged in the hand-held cylinder 4 from top to bottom. A paint replenishing mechanism is arranged in the cavity 5. The paint replenishing mechanism includes a micro electric push rod 7, a piston block 8 located below the micro electric push rod 7, and a spring 9 sleeved on the micro electric push rod 7. The micro electric push rod 7 is located above the hand-held cylinder 4, the telescopic rod body of the micro electric push rod 7 is located inside the hand-held cylinder 4, the piston block 8 is located inside the cavity 5, and both ends of the spring 9 are connected to the inner top surface of the cavity 5 and the piston block 8 respectively.

[0019] Combined with the attached Figure 1 、 Figure 3 、 Figure 4 Two pipes 10 are communicated and arranged below the cavity 5. Check valves 16 are respectively arranged on the pipes 10, and the flow directions of the check valves 16 are opposite. A flow cavity 11 is arranged inside the U-shaped bracket 1. A connecting pipe 12 communicated with the flow cavity 11 is arranged below the U-shaped bracket 1. A plurality of nozzles 13 communicated with the flow cavity 11 are arranged above the U-shaped bracket 1. At least five nozzles 13 are provided.

[0020] Combined with the attached Figure 1 、 Figure 2 A corrugated expansion pipe one 14 and a corrugated expansion pipe two 15 are respectively communicated and arranged on the pipes 10. The other end of the corrugated expansion pipe two 15 is communicated with the connecting pipe 12, and the other end of the corrugated expansion pipe one 14 is communicated with the paint bucket.

[0021] When the present utility model is specifically implemented, first, the staff controls the micro electric push rod to start, drives the piston block to extrude the paint from the cavity. The paint is sent to the connecting pipe through the pipe and the corrugated expansion pipe two, and then sent to each nozzle through the flow cavity, and the paint is sprayed onto the roller brush barrel by the nozzle. It is not necessary for the staff to continuously wave the entire roller brush barrel and immerse it in the paint bucket to replenish the paint, reducing the labor intensity of the staff. Then, the electric push rod is started to return. When returning, the piston block will be driven to reset. And because the cavity is in a vacuum state, under the action of the check valve, the reset of the piston block will cause the corrugated expansion pipe one to draw out the paint in the paint bucket and send it back into the cavity, facilitating the staff's next paint replenishing operation.

[0022] The above description is made on the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and without departing from the gist of the creation of the present utility model, they design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
