Description

Cleaning brush

Technical Field

The invention belongs to a cleaning brush, and particularly relates to a cleaning brush with a liquid storage tank.

Background

When a closestool or a squatting pan needs to be cleaned, when parts which are not soaked in water are cleaned, cleaning liquid is generally sprayed to the parts which need to be cleaned, excess or deficiency is easily caused, the use amount of the cleaning liquid is increased due to excess, the sewage discharge amount is increased, if the excess is not enough, the cleaning liquid is sprayed again, the operation steps are increased, and a cleaning liquid bottle and a cleaning brush are repeatedly used; when the part of the cleaning foam in water is cleaned, a large amount of cleaning liquid needs to be poured, and the diluted cleaning liquid is ensured to be above a certain concentration, so that the cleaning foam can be cleaned. Even the inner wall department of some closestool squats is mostly the dead angle, and the washing liquid can not accurately drip to this position.

At present, some cleaning brushes carrying cleaning liquid are developed for solving the problems, for example, a toilet brush disclosed in patent No. CN201720051239 can add cleaning liquid when the toilet brush is used, so that the problem of waste of cleaning agent of the toilet brush in the using process is solved, but cleaning work can be done, residual cleaning agent in the toilet brush drops due to the action of gravity, so that the waste of the cleaning agent is caused, and meanwhile, the problem that the cleaning agent in the toilet brush is polluted is solved. Also, patent CN103637736A discloses a drip-proof plunger type toilet brush, which has a drip-proof function compared with the above patent, wherein a cleaning liquid storage cavity is arranged between the brush head and the hollow brush handle and connected with the brush head and the hollow brush handle end to end, a cleaning liquid injection hole is arranged at the connection part of the cleaning liquid storage cavity and the brush head, and a one-way valve is arranged between the injection hole and the brush head. The cleaning liquid can be sprayed onto the brush head from the spray hole under the action of external extrusion force, and when no external force acts, the check valve plugs the spray hole under the action of the return spring. However, the one-way valve is arranged at the joint of the brush handle and the brush head, only the cleaning liquid above the brush handle can be saved when the jet orifice is sealed, and the cleaning liquid at the brush head still stays outside, thereby causing waste.

Furthermore, in order to clearly observe the amount of the cleaning liquid in the liquid storage tank 3, the cleaning liquid is added in time, and a transparent liquid level mirror 36 is arranged on the middle side wall of the liquid storage tank.

Further, the liquid outlet 44 has a tail portion having an opening 442, the opening 442 is communicated with the liquid outlet 43, the head portion 443 is made of a flexible material, and a closed slit 444 is formed in the middle of the head portion 443, and the slit 444 opens when a certain pressure is applied to the liquid in the opening 442.

Further, the liquid outlet holes 43 are arranged on the same side face of the brush head 4, so that the cleaning liquid is discharged from the same side face of the brush head 4, and the cleaning liquid is better sprayed to the part to be cleaned accurately.

The specific use and principle of the invention are as follows.

Before the first use, the present invention is placed upright, the plugging cover 32 is opened, and the cleaning solution is introduced into the reservoir 3 using a funnel or the like. The cleaning liquid enters the central hole 21 and the hollow part 14 through the communication pipe 34 and the one-way valve 35 respectively under the action of gravity, and the gravity cannot overcome the elastic force at the slit 444 of the liquid outlet 44 to push open the slit 444 of the head 443 of the liquid outlet 44, so that the gas or the liquid in the liquid conveying channel 42 flows out from the liquid outlet 44. When the liquid level of the cleaning liquid in the liquid storage tank 3 reaches the highest position, the cleaning liquid is stopped to be added.

When cleaning the sanitary ware, the side of the brush head 4 with the liquid outlet 43 is aligned with the part to be cleaned. The use process comprises a gripping process and a loosening process.

And (3) pressing: when the spring 11 is contracted by pressing the both-side pressing members 13 with a finger, the scissor type extending device 15 is changed from the contracted state to the extended state, the scissor type extending device 15 moves the piston 17 downward by pushing the push-pull rod 16 downward, the pressure of the hollow portion 14 is increased, and the liquid level of the cleaning liquid in the central hole 21 is pushed downward. The check valve 35 allows only the liquid to flow from the communication pipe 34 to the hollow portion 14, so that the cleaning liquid cannot flow from the hollow portion 14 into the communication pipe. The cleaning liquid in the hollow portion 14 pushes the air or liquid in the central hole 21 and the liquid feeding passage 42 to flow the air or liquid from the liquid outlet hole 43 to the liquid outlet 44. At this time, air or liquid under a certain pressure pushes open slits 444 at the head 443 of the liquid outlet 44, and is sprayed to the portion to be cleaned.

Loosening process: when the pressing piece 13 is released, the two ends of the upper part of the scissor type telescopic device 15 are pushed open under the action of the elasticity of the spring to change the scissor type telescopic device to the contraction state, so that the push-pull rod 16 and the piston 17 are pulled back upwards, the pressure of the hollow part 14 is reduced and is smaller than the atmospheric pressure to form negative pressure. The hollow portion 14 communicates with the center hole 21, so that the air pressure in the center hole 21 is negative. Under the action of atmospheric pressure, atmospheric air enters the tank 3 from the air-vent check valve 33 to push the cleaning liquid into the hollow portion 14 through the communication pipe 34 and the check valve 35, respectively. Gravity cannot overcome the elastic force at the slit 444 of the liquid outlet 44 and push the slit 444 of the head 443 of the liquid outlet 44, so that the gas or liquid in the liquid feeding channel 42 flows out of the liquid outlet 44. Until the air pressure in the central bore 21 and the air pressure in the reservoir 3 are in equilibrium.

During the cleaning process, the pressing process and the releasing process are repeated. The part to be cleaned, which is not soaked by water, is directly, accurately and quantitatively contacted by the cleaning liquid, so that the cleaning process is easily finished; the part with the bubbles can be sprayed by the cleaning fluid, so that the concentration of the cleaning fluid at the part can meet the requirement quickly, the brush bristles on the brush head can be used for cleaning quickly, the purpose of accurately putting in the cleaning fluid is achieved, and the using amount of the cleaning fluid is saved.

When the liquid level in the liquid storage tank 3 is observed to be lower than the stored liquid level from the liquid level mirror 36, the blocking cover 32 is opened, and the cleaning liquid is replenished.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
