Description

Technical Field

[0001] The invention relates to a cleaning brush, and in particular to a cleaning device suitable for cleaning a large number of sanitary appliances and waterless sanitary appliances. Background Art

[0002] In the traditional cleaning process of sanitary ware, the cleaning liquid is first sprayed on the cleaning part. When the cleaning brush is used for cleaning, if it is found that the cleaning liquid is not enough to clean the dirt, it is necessary to put down the cleaning brush, return to get the cleaning liquid bottle and spray again, then put the cleaning liquid bottle back, take the cleaning brush to clean, repeat the operation, and take the cleaning liquid bottle and cleaning brush back and forth, which is time-consuming. At the same time, after the cleaning is completed, the sanitary ware is generally flushed once with its own flushing system. Such a large amount of water is relatively large compared to the amount of water used to complete the cleaning of the residual cleaning liquid, resulting in a waste of water resources, especially for cleaning urinals. The cleaning work of public sanitary ware in large-scale public places requires a large amount of cleaning liquid to complete a comprehensive cleaning, which is a waste of time and water resources. The use of waterless sanitary ware is becoming more and more extensive, but it still needs to be cleaned regularly, and the flushing water required after cleaning is inconvenient to use.

[0003] In some prior art cleaning brushes with liquid storage tanks, the liquid storage tank and the brush rod are integrated, which makes the entire brush very heavy and inevitably limits the effective volume of the liquid storage tank. When spraying the cleaning liquid, it is necessary to pressurize it while using it. Only after the liquid is sprayed out by pressurization can the brush head be used to scrub the dirty parts conveniently. The liquid is discharged intermittently, which is time-consuming and laborious. Summary of the invention

The end of the upper rod 1521 is connected to a pressing plate. 1523, the area of ​​the pressing plate 1523 is larger than the opening 1111, the lower part of the middle rod 1522 passes through the rotating shaft 1524 fixed on the inner wall of the hollow part 111, one end of the spring 153 is fixed on the upper part of the middle rod 1522, and the other end of the spring 153 is fixed on the partition 14, the lower rod 1525 enters the liquid inlet pipe 151 and passes through the circular hole, and a flexible plug 1526 is fixed at the end of the lower rod 1525, and the area of ​​the plug 1526 is larger than the area of ​​the circular hole, and the sealing spring 154 is wrapped on the pressing plate 1523 and fixed on the hand-held part 11 to seal the opening 1111.

[0017] The liquid storage tank 2 is separated into two sealed boxes by an intermediate plate 21. A liquid outlet pipe 22 is provided on the outer side of the lower part of the box body. The liquid outlet pipe 22 is connected to the liquid inlet pipe 151 through a hose 3. A liquid inlet 23 is provided on the top of the box body. A sealing cover 24 is provided on the liquid inlet 23. The lower end of a cylinder 25 is fixed on the top of the liquid storage tank 2. An upper baffle 251 is provided on the upper end of the cylinder 25. A connecting rod 252 passes through the upper baffle 251. A piston 253 is fixed on the lower end of the connecting rod 252. A push rod 254 is fixed at the upper end, and a lower baffle 256 with a through hole 255 is arranged below the piston 253 inside the cylinder 25. A one-way ventilation valve 257 for intake of air from the outside to the cylinder 25 is arranged on the side wall of the cylinder 25 below the lower baffle 256. Two one-way air intake valves 258 from the cylinder 25 to the liquid storage tank 2 are arranged on the side wall at the top of the liquid storage tank 2 in the cylinder 25. The two one-way air intake valves 258 are distributed on both sides of the middle plate 21, and a roller 26 is arranged at the bottom of the liquid storage tank 2.

[0018] A liquid level observation mirror 27 is provided on the vertical outer wall of the liquid storage tank 2, and upper and lower limit scales of the liquid level are marked near the observation mirror 27.

[0019] The use process and principle of the present invention are as follows.

[0020] Before use, check the liquid level in the box through the observation mirror 27. When the liquid level reaches the lower limit scale, open the sealing cover 24 and add corresponding cleaning liquid or clean water into the box through the liquid inlet 23. When the liquid level reaches the upper limit scale, stop adding liquid, tighten the sealing cover and set it aside.

[0021] During the pressurization process in the liquid storage tank 2, the push rod 254 is pulled up to move the piston 253 upward until the piston 253 presses against the upper baffle 251. During this process, the gas enters the cylinder 25 from the outside through the one-way vent valve 257. Then the push rod 254 is pressed down, so that the piston 253 moves downward, squeezing the gas in the cylinder 25 and increasing its pressure, and the high-pressure gas enters the liquid storage tank 2 from the cylinder 25 through the one-way intake valve 258. The gas in the upper part of the liquid storage tank 2 increases, but the volume remains unchanged, and the upper air pressure must increase. The push rod 254 is repeatedly pushed and pulled in this way, thereby continuously increasing the gas pressure in the liquid storage tank 2 until the predetermined pressure is reached.

[0022] When cleaning liquid is needed, the liquid outlet 134 connected to the cleaning liquid in the brush head 13 is aligned with the cleaning part, and the corresponding pressing plate 1523 is pressed. The pressing plate 1523 pushes the upper rod 1521 inward, and the upper rod 1521 pushes the middle rod 1522 and the spring 153 toward the partition 14. The spring 153 is squeezed, and the middle rod 1522 rotates around the rotating shaft 1524. The lower end of the middle rod 1522 pushes the lower rod 1525 outward, and the lower rod 1525 pushes the plug 1526 outward, so that the plug 1526 is separated from the protrusion 1511, and a gap is formed between the plug 1526 and the protrusion 1511. The high-pressure gas inside the liquid storage tank 2 pushes the cleaning liquid, which is pushed into the liquid inlet pipe 151 through the hose 3, passes through the gap formed between the plug 1526 and the protrusion 1511, and enters the hollow part 111, the middle hole 121 and the infusion channel 132. At this time, the cleaning liquid with a certain hydraulic pressure can push open the one-way liquid outlet 134 and spray from the liquid outlet 133 to the part to be cleaned. When it is not necessary to spray the cleaning liquid, after releasing the pressing plate 1523, the compressed spring 153 rebounds and pushes the upper end of the middle rod 1522 outward, the middle rod 1522 rotates around the rotating shaft 1524, and the lower end of the middle rod 1522 pulls back the lower rod 1525 inward, and the lower rod 1525 pulls back the plug 1526, and the plug 1526 is in close contact with the edge of the protrusion 1511 to prevent the liquid from flowing.

[0023] When using clean water for flushing, align the liquid outlet 134 of the brush head 3 connected to the clean water with the cleaning part, and press the corresponding pressing plate 1523. The process is the same as when using the cleaning liquid.

[0024] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
