The following describes a specific structure of the surface cleaning machine of the present application with reference to the drawings.
The first embodiment of the present application:
as shown in fig. 1 to 3, the surface cleaning machine of the present embodiment includes a body 11, a hand-held lever 12, a fresh water tank 13, and a foul water tank 14, and a cleaning roller brush 111, a foul water tank 112, and a soil pump 15 provided at the body 11. The hand-held lever 12 is hinged to the body 11, and the user can control the traveling direction of the body 11 by moving the hand-held lever 12. The cleaning roller brush 111 is pivotally connected to the body 11, and the rotating cleaning roller brush 111 can wipe and clean a surface to be cleaned. The clean water tank 13 is used to supply a cleaning liquid (clean water, a cleaning agent or a clean water cleaning agent mixture) to the cleaning roller brush 111 or the surface to be cleaned to assist the cleaning operation of the cleaning roller brush 111. The body 11 is provided with a scraping member 113, the scraping member 113 is used for scraping and squeezing the cleaning roller brush 111 to scrape off the sewage and dirt adsorbed or carried by the cleaning roller brush 111, and the sewage box 112 is used for receiving the scraped sewage and dirt.
It should be noted that the surface cleaning machine of the present embodiment may be provided with one cleaning roller brush, or may be provided with two cleaning roller brushes, which is not limited in the present embodiment.
Referring to fig. 2 and 3, the suction pump 15 communicates with the sewage tank 112 through a suction pipe 151, and the suction pump 15 communicates with the sewage tank 14 through a sewage pipe 152, the length of the suction pipe 151 being smaller than that of the sewage pipe 152. The process that the sewage pipe 152 extends to the sewage tank 14 by the sewage pump 15 can pass through the hinged position of the handheld rod 12 and the machine body 11, and in order to avoid the damage to the sewage pipe 152 caused by the rotation of the handheld rod 12, the anti-folding section 1521 (such as a water pipe with deformation allowance such as a corrugated pipe or a soft water pipe which is easy to deform) is arranged at the part of the sewage pipe 152, which is positioned at the hinged position of the handheld rod 12 and the machine body 11. The sewage suction pump 15, which is turned on, can suck in the sewage flowing into the sewage box 112 through the sewage suction pipe 151 and then deliver the sewage into the sewage tank 14 through the sewage discharge pipe 152. Preferably, the soil pipe 152 communicates with the top of the wastewater tank 14, thereby reducing the risk of water leakage and facilitating the disassembly of the wastewater tank 14.
As can be understood by those skilled in the art, by providing the sewage box 112 in the surface cleaning machine and making the length of the sewage suction pipe 151 smaller than that of the sewage discharge pipe 152, the distance between the sewage suction pump 15 and the dirty object is smaller, that is, the suction path of the sewage suction pump 15 is shortened, so that the loss of the suction force generated by the sewage suction pump 15 in the suction process is reduced, and the sewage suction efficiency of the sewage suction pump 15 is improved. Meanwhile, the suction loss of the sewage pumping pump 15 is reduced, so that the sewage pumping pump 15 can utilize smaller working power to achieve the same sewage suction effect, the running power of the sewage pumping pump 15 during working is reduced, the energy consumption of the sewage pumping pump 15 is reduced, and the working noise of the sewage pumping pump 15 is reduced.
As shown in fig. 2 and 3, a solid-liquid separation part 1121 is further provided in the sewage box 112, and the solid-liquid separation part 1121 is a filter net, specifically, the solid-liquid separation part 1121 is a plate-shaped structure protruding from the bottom wall of the sewage box 112, and the filter net is formed by forming filter holes in the plate-shaped structure. The solid-liquid separation portion 1121 partitions the sewage box 112 into a front chamber 1122 and a rear chamber 1123, the sewage and the filth scraped off by the scraper 113 first flow into the front chamber 1122 of the sewage box 112, then some large-sized filth is blocked in the front chamber 1122, and some small-sized filth and sewage pass through the filtering holes of the filter screen into the rear chamber 1123. An inlet of the sewage pump 15 is communicated with the rear chamber 1123, and the sewage entering the rear chamber 1123 after being filtered by the solid-liquid separation portion 1121 is pumped into the sewage tank 14 by the opened sewage pump 15.
It can be understood by those skilled in the art that, during the cleaning operation of the surface cleaning machine, the dirt adsorbed and carried by the cleaning roller brush 111 can be scraped away by the scraping member 113 and flows into the dirt box 112, then the mixed dirt flowing into the dirt box 112 is processed by the solid-liquid separation part 1121, the dirt and the small-sized dirt are further separated, the separated dirt and the small-sized dirt are further pumped into the dirt tank 14 by the dirt pumping pump 15, and the dirt pumping pump 15 is communicated with the dirt box 112 to close the space pumped by the dirt pumping pump 15, so as to further reduce the suction loss of the dirt pumping pump 15. In addition, the sewage pump 15 pumps the sewage and the small-sized sewage separated by the solid-liquid separation part 1121, so that the sewage pump 15 is allowed to use a smaller suction force, which is advantageous for reducing the working noise of the sewage pump 15.
It should be noted that, the filter screen may be provided with filter holes, or may be provided with horizontal or vertical strip-shaped slits. Further, the solid-liquid separation section may be constituted by providing a plurality of separation columns having gaps, and the same function may be achieved.
Referring to fig. 3, it is preferable that the diameter of the sewage suction pipe 151 is not smaller than the diameter of the sewage discharge pipe 152 because the sewage in the sewage box 112 is sucked into the sewage suction pump 15 and then is impacted and further dispersed, so that the diameter of the sewage suction pipe 151 is not smaller than the diameter of the sewage discharge pipe 152, and the blockage of the sewage suction pipe 151 can be prevented.
The specific structure of the surface cleaning machine of the present embodiment will be further described below.
As shown in fig. 2 and 3, the sewage box 112 includes a box cover 1124 and a box body 1125, the box cover 1124 has a guide portion 1126 and a sewage receiving hole 1127, and after the box cover 1124 is closed on the box body 1125, the sewage receiving hole 1127 is aligned with the front chamber 1122. The guide part 1126 is adjacent to the cleaning roller brush 111, and the sewage and dirt scraped off by the scraping member 113 can fall on the guide part 1126, flow along the guide part 1126 to the dirt receiving hole 1127, and then flow from the dirt receiving hole 1127 to the front chamber 1122.
It should be noted that, the sewage box may not be provided with a box cover, but the sewage box may be integrally formed to form a guide portion, and the sewage and the filth directly enter the front chamber along the guide portion. In addition, the waste water box 112 is detachably connected to the machine body 11, so that the waste water box 112 can be detached to clean the dirt in the front chamber 1122.
As shown in fig. 4, the body 11 is further provided with a liquid supply pump 16 and a motor 17, the liquid supply pump 16 is communicated with the clean water tank 13, and the opened liquid supply pump 16 delivers the cleaning liquid in the clean water tank 13 to the cleaning roller brush 111 or the surface to be cleaned. The motor 17 is used to drive the cleaning roller brush 111 to rotate. Preferably, the sewage pump 15 and the liquid supply pump 16 are installed at one side of the body 11, and the motor 17 is installed at the other side of the body 11.
As can be understood by those skilled in the art, on the one hand, by disposing the sewage pump 15 on the machine body 11, the sewage pump 15 is closer to the sewage box 112, which is beneficial to further shorten the length of the sewage pumping pipe 151, so that the pumping path of the sewage pump 15 is shorter, thereby further reducing the suction loss of the sewage pump 15. And, it helps to move the overall center of gravity of the surface cleaning machine down, thereby facilitating user control of the surface cleaning machine. On the other hand, through setting up fluid feed pump 16 and sewage pump 15 in the same side of organism 11 to set up motor 17 in the opposite side of organism 11, make heavier part concentrate on organism 11, help the focus of surface cleaning machine to move down, and, make the gravity of organism 11 both sides to be balanced partially, thereby make organism 11 move more steadily at the in-process of carrying out cleaning, and make the pressure that cleaning roller brush 111 received comparatively balanced, guarantee the holistic clean effect of cleaning roller brush 111.
Referring back to fig. 3, the connection point of the dirty pipe 151 and the rear chamber 1123 is located on the side wall of the rear chamber 1123 and is in close contact with the bottom wall of the rear chamber 1123, a guide surface (not shown) inclined from the solid-liquid separation portion 1121 to the connection point of the dirty pipe 151 and the rear chamber 1123 is provided on the bottom wall of the rear chamber 1123, and the connection point of the dirty pipe 151 and the rear chamber 1123 is located at the lower position of the inclined guide surface, so that the dirty entering the rear chamber 1123 can flow into the dirty pipe 151 quickly under the guide of the guide surface.
Those skilled in the art can understand that the above structure makes the sewage pumping pipe 151 a horizontal straight section, which is not only beneficial to shortening the length of the sewage pumping pipe 151, but also makes the air flow and the dirt move more smoothly in the straight sewage pumping pipe 151, and when the suction loss is reduced, the sewage pumping pipe 151 is also made to be less likely to be blocked, thereby improving the sewage pumping efficiency of the sewage pumping pump 15. And, the connection with the sidewall of the rear chamber 1123 makes the suction pipe 151 also easy to connect the suction pipe 151 and the soil box 112.
The guide surface may be a straight inclined surface or an arc surface.
In addition, it should be noted that the sewage pumping pump of this embodiment is a self-priming water pump or a vacuum water pump with an operating voltage of not more than 24V. And the sewage pumping pipe is a hard pipe, and the sewage draining pipe is a silica gel hose.
As can be understood by those skilled in the art, on the one hand, because the sewage suction pipe is shorter and is positioned in a machine body with a larger space, the sewage suction pipe can be more easily fixed by setting the sewage suction pipe to be a hard pipe, so that the shaking of the sewage suction pipe in the suction process is reduced, and the reduction of the working noise of the surface cleaning machine is facilitated. On the other hand, because the blow off pipe is than longer and the main part is located the less handheld pole in space, handheld pole just can play limiting displacement to the blow off pipe, consequently, through setting up the pipe of taking out the dirt into the silica gel hose for the installation work of blow off pipe is more convenient, and in addition, under the condition of the activity of handheld pole restriction hose, the silica gel hose can absorb the impact force of some rivers, thereby reduces the noise of rivers.
Referring to fig. 1 to 4, during the cleaning operation of the surface cleaning machine, the cleaning roller brush 111 is driven by the motor 17 to rotate, the rotating cleaning roller brush 111 wipes the surface to be cleaned, the cleaning liquid in the fresh water tank 13 is delivered to the cleaning roller brush 111 or the surface to be cleaned by the liquid supply pump 16, and the cleaning roller brush 111 is assisted to clean. The cleaning roller brush 111 absorbs or rolls up dirt on a surface to be cleaned, when the dirt absorbed or carried by the cleaning roller brush 111 reaches the scraping piece 113 along with the rotation of the cleaning roller brush 111, the dirt absorbed or carried by the cleaning roller brush 111 is scraped off from the cleaning roller brush 111 by the scraping piece 113 due to the scraping of the cleaning roller brush 111 by the scraping piece 113, and the scraped-off dirt flows to the dirt accommodating hole 1127 through the guide part 1126 of the dirt box 112 and then flows into the front chamber 1122 of the dirt box 112 through the dirt accommodating hole 1127. The dirt flowing into the front chamber 1122 is a mixture of sewage and dirt, wherein large-sized dirt is blocked in the front chamber 1122 by the solid-liquid separation part 1121, the sewage and small-sized dirt pass through the filtering holes of the solid-liquid separation part 1121 to enter the rear chamber 1123, and the dirt entering the rear chamber 1123 is pumped away by the sewage pumping pump 15 through the sewage pumping pipe 151 and is conveyed into the sewage tank 14 through the sewage discharge pipe 152.
As can be understood by those skilled in the art, by providing the sewage box 112 in the surface cleaning machine and making the length of the sewage suction pipe 151 smaller than that of the sewage discharge pipe 152, the distance between the sewage suction pump 15 and the dirty object is smaller, that is, the suction path of the sewage suction pump 15 is shortened, so that the loss of the suction force generated by the sewage suction pump 15 in the suction process is reduced, and the sewage suction efficiency of the sewage suction pump 15 is improved. Meanwhile, the suction loss of the sewage pumping pump 15 is reduced, so that the sewage pumping pump 15 can utilize smaller working power to achieve the same sewage suction effect, the running power of the sewage pumping pump 15 during working is reduced, the energy consumption of the sewage pumping pump 15 is reduced, and the working noise of the sewage pumping pump 15 is reduced. In addition, during the cleaning operation of the surface cleaning machine, the dirt adsorbed and carried by the cleaning roller brush 111 can be scraped away by the scraping member 113 and flows into the dirt box 112, then the mixed dirt flowing into the dirt box 112 is treated by the solid-liquid separation part 1121, the sewage and the small-sized dirt are further separated, the separated sewage and the small-sized dirt are pumped into the sewage tank 14 by the sewage pumping pump 15, and the sewage pumping pump 15 is communicated with the dirt box 112 to enable the space pumped by the sewage pumping pump 15 to be closed, so that the loss of the suction force of the sewage pumping pump 15 is further reduced. In addition, the sewage pump 15 pumps the sewage and the small-sized sewage separated by the solid-liquid separation part 1121, so that the sewage pump 15 is allowed to use a smaller suction force, which is beneficial to reducing the working noise of the sewage pump 15
Further, through setting up the sewage pump 15 on organism 11 for sewage pump 15 is close to sewage box 112 more, is favorable to further shortening the length of taking out dirty pipe 151, makes the suction route of taking out dirty pump 15 shorter, thereby further reduces the suction loss of taking out dirty pump 15.
