Description

[Detailed description of the invention] [Industrial application field] This invention relates to a brush device, in particular, which is connected to a suction/drainage pump and supplies liquids such as cleaning water or paint, or removes liquids that adhere to objects to be cleaned. This invention relates to an improvement of a brush device for forcibly sucking water droplets, etc., and wiping away contamination on the vessel wall surface by reciprocating movement.

[Prior art]

As a conventional brush device of this type, those shown in FIGS. 3 and 4 are known. This brush device B' includes a brush main body 1 in which a hollow part 2 is formed, a plurality of bristles 3 planted on a bristle surface 1a of this main body 1, and a hollow part 2 that extends through the surface 1a. A connection port 5 having a plurality of through holes 7 formed to communicate with the brush body 1 and an opening 4 formed in one side of the brush body 1 and communicating with the hollow portion 2, and a tube 6 connected to the connection port 5. Pump P connected in communication
Liquids such as cleaning liquid and paint sucked and discharged by the pump P are pump P-tube 6.
- It is configured to flow through the opening 4 of the connection port 5 - the hollow part 2 - the through hole 7.

[Problems with conventional technology]

However, in the case of the conventional brush device B′,
When cleaning, wiping, etc. by pressing the bristle body 3 against an object to be cleaned, etc., the so-called bristle falling phenomenon occurs due to the pressure force, and this causes the bristle body 3 to break, resulting in an uneven pressure force. However, there were problems in that cleaning was uneven and a uniform coating finish could not be obtained.

In addition, in the case of the conventional brush device B′ mentioned above,
During water feeding, liquids such as cleaning water and paint are pumped through the through holes 7 toward the bristles.
When the through holes 7 are broken, etc., the through holes 7 are likely to be blocked, and it is difficult to obtain uniform injection pressure for each through hole 7, which is a problem.

Furthermore, in the case of the conventional brush device B′ mentioned above,
When this is used for water absorption, air is sucked together with water droplets attached to the bristles 3 from each through hole 7 as shown in FIG. Since a plurality of pumps are provided, the amount of air sucked out is large compared to the proportion of water droplets sucked in, so there was a problem in that the pump P had to be made larger.

Furthermore, in the case of the conventional brush device B', dirt adhering to the bristles 3 is easily collected when the bristles 3 break or break, so it is cleaned by liquid etc. sprayed from the through hole 7. It also had the problem of being difficult to eliminate.

[Purpose of invention]

This device was devised in view of the current situation, and its purpose is to prevent dirt from adhering, to keep the bristles upright during use to prevent uneven cleaning, and to automatically reciprocate the surface of the vessel wall. It is an object of the present invention to provide a brush device with a simple structure that can sufficiently wipe the surface of the brush, provide a uniform finished surface in the case of painting, and can be operated effectively even with a small pump.

[Structure of the idea]

In order to achieve the above object, this invention includes a brush body having a hollow portion formed inside, a plurality of bristles implanted on the bristle surface of the brush body, and a side portion of the brush body. Each bristle body of the brush device is composed of a connection port having an opening communicating with the hollow portion, and a suction/drainage pump connected to the connection port, the upper end of which is closed, and the lower end of which is connected to the hollow portion. In addition to forming a communicating hollow part of the hair body, a plurality of holes are regularly or irregularly opened on the circumferential surface of each hair body to communicate the outside of the hair body and the hollow part of the hair body. be.

〔Example〕

This invention will be explained in detail below based on an embodiment shown in FIGS. 1 and 2.

As shown in FIG. 1, the brush device B according to this embodiment includes a brush body 11 made of a synthetic resin material or the like and having a hollow portion 12 formed therein, and a brush body 11 that has bristles implanted on the implanted surface of the brush body 11. a plurality of bristles 13 made of a material such as synthetic resin, a connection port 15 formed integrally with one side of the brush body 11 and having an opening 14 communicating with the hollow portion 12; It consists of a suction and drainage pump P connected to the mouth 15 through a tube 16, and the bristles 13 are reciprocated along the wall surface (not shown) by a known solenoid mechanism or the like, so that they can be wiped. There is.

As shown in FIG. 2, each bristle body 13 formed in an inverted U-shape in longitudinal section has a bristle hollow part 18 formed in the middle thereof, the upper end of which is closed, and the lower end of which communicates with the hollow part 12 of the brush body 11. In addition, a plurality of holes 19 are provided regularly or irregularly in the circumferential surface 13a of the hair body 13 to communicate the outside of the hair body and the hair body hollow part 18. In addition, the reference numeral 13b in FIG. 2 indicates a flange F extending from the lower end portion of the bristles 13 indicating a water-absorbing material layer.

Each of the bristles 13 configured in this way is opened regularly or irregularly on the bristled surface 11a of the brush body 11, and is inserted into the hole 17 communicating with the hollow part 12 and fixed with adhesive so that it cannot be removed. . Thereby, the hair body hollow part 18 and the hollow part 12 of each hair body 13 are communicated with each other.

Next, the operation of the brush device B configured as described above will be explained. When the pump P sends out cleaning water, for example, the cleaning water sucked into the pump P flows from the tube 16 to the hollow part 1 of the brush body 11.
2, it flows into the hair body hollow part 18 of each hair body 13 and is sprayed from each hole 19 to the outside of the hair body.
Therefore, in this case, the bristles 13 are kept in an upright state by the pressure of the washing water flowing into the hollow part 18 of the bristles, so each bristle 13 is held against the surface of the object to be cleaned with an average pressure. There is no risk of breakage, and the peripheral surface 13a of the bristles 13 is less likely to be contaminated by cleaning water sprayed from the holes 19.

In addition, when the water droplets adhering to the surface of the object to be cleaned are wiped and sucked by the pump P, the water droplets are adsorbed on the surface of the bristles 13 while being reciprocated along the wall surface of the device, and then the water droplets are sucked from the holes 19 through the bristles. It is sucked into the hollow part 18, and then the hollow part 12 → tube 16 → pump P
→It is discharged to the designated drainage area. In this case, water droplets are sucked through the plurality of holes 19 even when the bristles 13 are in a fallen state.

[Effect of idea]

This idea was constructed as explained above, so
When delivering cleaning water or paint, etc., the bristles stand upright and evenly contact the surface to be contacted, so the container wall surface is sufficiently wiped and there is no possibility of uneven cleaning or coating, and there is a risk of breakage. In addition, there is no need to worry about the suction hole being blocked by broken bristles during suction, which not only improves suction efficiency but also allows the pump to be made smaller.
