Description

A multi-filter water squeezing strip, cleaning head and cleaning appliance

Technical field

The utility model relates to the technical field of cleaning machinery, and in particular to a multi-filter water squeezing strip, a cleaning head and a cleaning appliance used in a floor washing machine.

Background technique

The early floor cleaning tools used by people were brooms, mops, floor wipes, etc. These tools mainly relied on people's manual operation to complete the cleaning work. With the advancement of science and technology, people's requirements for floor cleaning tools have gradually increased. The first thing that appeared was the vacuum cleaner, which relies on electricity to supply energy and generates negative pressure to absorb garbage, dust, etc. on the ground. Classified from the cleaning methods and the circulation paths of small particle garbage and large particle garbage, this type of technology is usually classified as air and dust circulation technology. However, due to the limitation of its working principle, the vacuum cleaner cannot clean some garbage and stains that are firmly attached to the ground. Therefore, a new "water and dust circulation" floor scrubber has appeared, which uses the operation of the motor to drive the cleaning roller to wipe the floor. The cleaning roller usually adopts a sponge tube structure. The cleaning ability of the floor cleaner is related to the thickness of the sponge tube. The thicker the sponge tube, the stronger its cleaning ability. At the same time, the floor cleaner will also be equipped with a water supply system and a sink to clean the cleaning cylinder, thereby perfectly cleaning the floor. In order to clean the cleaning cylinder, a closed cleaning space connected to the water supply system is usually set up to clean the partial roller, provide clean water to clean the cleaning cylinder, and then pump away the sewage after cleaning the cleaning cylinder.

The brush roller equipped with the floor scrubber using water and dust circulation technology is installed in the cleaning head and is used to sweep the garbage lifted up by the sponge roller to the garbage box. The brush roller does not need to sweep the floor and only needs to clean the ground in the closed The lower rear section of the cleaning space sweeps the surface of the sponge roller before it is washed by clean water in the closed cleaning space, and sweeps the garbage outside the water flow channel blocked by the filter device of the closed cleaning space to the garbage box.

Chinese patent CN216393963U discloses a cleaning head and cleaning equipment. The cleaning head includes a body provided with a roller. The body is provided with a strip cavity. Pressure water is provided on both sides of the opening of the cavity to exert pressure on the surface of the roller. strips and scraping strips for scraping off solid garbage on the surface of the drum. The water pressure strips, scraping strips and cavities form a closed cleaning water tank with the surface of the drum. A cleaning water tank is provided in the cleaning water tank to separate the cleaning area and the water collection area. Water strips. When in use, the clean water on the surface of the cleaning drum flushes the drum. Since the water dividing strip divides the cleaning tank, it is avoided that the clean water will reattach the fine granular garbage in the cleaning tank to the surface of the drum during cleaning, thereby improving the cleaning efficiency of the drum. It can also prevent the fine granular garbage on the surface of the drum from adhering to the cleaning surface again during the cleaning process, affecting the cleaning efficiency.

Chinese patent CN215874506U discloses a cleaning head and cleaning tool for cleaning tools. The cleaning head includes: a first roller; a sink assembly with a flip cover, which is arranged above the first roller; and an integrally detachable second roller assembly, which includes a second roller, and the second roller is arranged on the first roller. Behind the rotation direction of a drum; an integrally detachable garbage box assembly is provided behind the second drum. By setting up the sink assembly with a flip cover, when larger garbage enters the sink, the flip cover can be opened, the garbage can be taken out, and the sink can be cleaned or placed in the water flow for cleaning without the need to disassemble the sponge roller to take out the garbage, which is convenient and quick to use; The integrally detachable second roller assembly and garbage box assembly make cleaning the brush and garbage box more convenient and faster; in addition, the garbage box can be automatically opened by pressing a button, which reduces the contact between people and garbage and is more hygienic. Figure 3 of the description and paragraph 70 of the description disclose that the sink assembly with a flip cover includes a flippable sink sealing cover, a sink shell, a water squeeze filter device and a water sealing device. The sink housing is connected to the second housing of the cleaning head. A flippable water tank sealing cover is provided above the water tank shell and is used to seal or open the water tank assembly. The water squeezing filter device is arranged below the water tank housing, contacts the surface of the first drum, squeezes the first drum, and promotes the discharge of dirty water in the first drum. The water sealing device is arranged below the water tank housing and in contact with the surface of the first drum. The water squeezing filter device, the water sealing device, and the surface of the first drum form a water storage space connected with the water tank shell.

The cleaning cylinder scraper or water squeezing filter device configured in the water and dust circulation cleaner in the prior art only realizes the sewage extrusion function of part of the sponge drum. The scraper increases the scraping teeth and increases the contact area with the sponge drum (hanging teeth). There is a small amount of interference fit with the sponge roller, and the recessed part of the sponge roller increases the contact area with the scraper teeth), even after adding a filter structure (a certain number of holes with a certain aperture are provided on the scraper or water squeezing filter device close to the sponge roller) through holes), the filtration is still insufficient, and at the same time, the clean water and the sewage after extrusion and filtration are not partitioned, or some of the clean water does not fully flush the sponge roller, and the sewage is directly mixed and flows away, which affects the cleaning ability of the sponge roller. Further improvements are needed to improve cleaning efficiency.

In the prior art, as shown in Figures 1 to 3, the water squeezing strip 3 is installed on the housing 10 of the cleaning head 1 for floor washing. The water squeezing strip 3 squeezes the surface of the cleaning roller 2, and the water squeezing strip 3 is installed On one of the vertical cleaning roller guard plates (not shown in the drawings) inside the housing 10, there is a vertical plate (not shown in the accompanying drawings) on the opposite side of the guard plate, and the water support strip 4 is installed on the vertical plate. On the board, part of the surface of the water squeezing strip 3, part of the surface of the cleaning roller 2, part of the surface of the water support bar, part of the surface of the vertical plate, and part of the surface of the cleaning roller guard can allow clean water to continue to hit the upper surface of the cleaning roller. A cleaning tank (not shown in the accompanying drawings) for rinsing is also provided with a removable flip cover 11 directly above the cleaning tank. The water squeezing strip 3 includes a water squeezing part 31 , an extension part 32 and a water diverting hook 33 . The water squeezing part 31 extends toward the axial direction of the cleaning roller 2, scraping and squeezing the surface of the cleaning roller 2 to scrape off the liquid and solid particle garbage adhered to the surface of the cleaning roller 2. The sewage on the surface of the cleaning roller 2 after being rinsed with clean water is mixed with Fine-grained garbage is also squeezed out by the water-squeezing strip 3. The extension portion 32 extends from the water squeezing portion 31 along the tangential direction of the surface of the cleaning roller 2, and along the rotation direction of the cleaning roller 2, gradually pre-compresses the surface of the cleaning roller 2 from a free state to a state about to be squeezed. There is a large gap between the lower surface of the extension part 32 and the upper surface of the cleaning roller 2. The gap between the lower surface of the extension part 32 and the upper surface of the cleaning roller 2 provides a smooth path for the sewage mixed with fine-grained garbage scraped by the water squeezing part 31. Flow channel, for ease of discussion, we call this channel stratospheric region A. The water separating hook 33 extends from the extension portion 32 in a direction away from the cleaning roller. The extension part 32 is evenly distributed with filtering through holes 321 penetrating its upper surface and lower surface. Although the extension part 32 is evenly distributed with filter holes 321 penetrating its upper and lower surfaces, due to the large gap between the lower surface of the extension part 32 and the upper surface of the cleaning roller 2, more clean water has not yet penetrated deeply into the upper surface of the cleaning roller 2. The flushing process is mixed with the sewage scraped out by the water squeezing part 31 and flows along the stratosphere area A on the upper surface of the cleaning roller 2 to the collecting area E of the cleaning tank and is then pumped away by the sewage pipeline. The cleaning efficiency of the clean water needs to be improved. . The sewage can only be pumped away by the sewage pipeline (not shown in the attached figure) after it reaches the collection area E. When there is solid garbage, liquid garbage or mixed garbage on the surface to be cleaned, the cleaning roller 2 first lifts the solid garbage, liquid garbage or mixed garbage through the shovel bar 5 into the garbage guide channel (not shown in the drawing), and then the brush roller 6. Further sweep the solid garbage that has passed through the garbage guide channel into the garbage box (not shown in the attached figure). Some sticky garbage, liquid garbage and fine particle garbage are difficult to be swept away by the brush roller 6 and will be further swept away. The pump passes through the tip of the water support bar 4 (not shown in the drawings) and the water squeezing part 31 of the water squeezing bar 3 in sequence. The water squeezing part can scrape the sticky garbage, liquid garbage and mixed garbage mixed with fine particles of garbage together. The upper surface of the cleaning roller 2 is extruded and then further washed away by the clean water in the cleaning tank, thereby cleaning the floor to be cleaned.

In the first aspect, as shown in Figures 4 to 14, the utility model provides a multi-filter water squeezing strip, which is installed on the housing 10 of the cleaning head 1 of the floor washing machine. The water squeezing strip 3 squeezes the cleaning roller. 2 surface, the water squeezing strip 3 includes a water squeezing part 31, an extension part 32 and a water diverting hook 33. The water squeezing part 31 extends toward the axial direction of the cleaning roller 2, scraping and squeezing the surface of the cleaning roller 2 to scrape off the liquid and solid particle garbage adhered to the surface of the cleaning roller 2. The sewage on the surface of the cleaning roller 2 after being rinsed with clean water is mixed with Fine-grained garbage is also squeezed out by the water-squeezing strip 3. The extension portion 32 extends from the water squeezing portion 31 along the tangential direction of the surface of the cleaning roller 2, and along the rotation direction of the cleaning roller 2, gradually pre-compresses the surface of the cleaning roller 2 from a free state to a state about to be squeezed. There is a slight elastic gap between the lower surface of the extension part 32 and the upper surface of the cleaning roller 2, and between the lower surface of the extension part 32 and the upper surface of the water support bar 4. The extension part 32 is evenly distributed with filters that penetrate its upper surface and lower surface. The diameter of the through hole 321 and the filter through hole 321 is larger than the minimum gap between the lower surface of the extension part 32 and the upper surface of the cleaning roller 2 . The water separation hook 33 extends from the extension part 32 in the direction away from the cleaning roller, dividing the cleaning tank into a plurality of water flow filtering areas. Since the extension part 32 is evenly distributed with filter through holes 321, it is squeezed out by the water squeezing part 31. The sewage on the surface of the cleaning roller 2 is mixed with fine-grained garbage and reaches different areas of the cleaning tank in two ways. One way is sewage mixed with larger-grained garbage and reaches the first filter area B through the filter through hole 321. The other way is sewage mixed with smaller-grained garbage. After passing through the stratosphere area A, it flows through the elastic gap between the lower surface of the extension part 32 and the upper surface of the cleaning roller 2, and between the lower surface of the extension part 32 and the upper surface of the water support bar 4, and reaches the collection area E. The water-dividing hook 33 is evenly distributed with filtering through holes 331 penetrating its front surface and rear surface, and the diameter of the filtering through holes 331 is smaller than the diameter of the filtering through holes 321 of the extension part 32 . After the sewage passes through the first filtering area B, it can continue to filter finer particles of garbage through the filtering through holes 331, and the sewage that continues to pass through the filtering through holes 331 can further flow into the collection area E. When the flow of sewage in the first filtering area B is large and there is no time to continue filtering finer particles of garbage, the sewage can roll over the top of the water separation hook 33 and then fall into the collection area E.
