The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1-3, a surface cleaning apparatus according to an embodiment of the present invention has a roller brush 6 on a cleaning head 4 for cleaning a surface to be cleaned. The cleaning head 4 is also provided with a sewage tank 16 for recovering sewage on one side of the rolling brush 6, the sewage tank 16 comprises a body with a sewage storage chamber 12 and a sewage guide chamber 13 arranged on one side of the body close to the rolling brush 6, and the sewage guide chamber 13 is communicated with the sewage storage chamber 12. The sewage guide chamber 13 comprises a guide plate 15, and the sewage on the roller brush 6 enters the sewage guide chamber 13 through the guide plate 15 and then enters the sewage storage chamber 12 through the sewage guide chamber 13 to be collected.

The sewage guide chamber 13 further comprises a first scraping strip 14, and the first scraping strip 14 and the guide plate 15 are arranged at intervals. As shown in the figure, in the present embodiment, the first scraping strip 14 is disposed above the flow guide plate 15, and when the surface of the rolling brush 6 rotates past the first scraping strip 14, the first scraping strip 14 can scrape off the sewage on the surface of the rolling brush 6, and the scraped sewage flows into the sewage tank 16 along the flow guide plate 15. Preferably, the guide plate 15 is made of soft rubber, and the first scraping strip 14 and the guide plate 15 are in interference fit with the surface of the rolling brush 6; therefore, when the surface of the rolling brush 6 passes through the guide plate 15, the sewage on the surface of the rolling brush cannot be scraped, and when the surface of the rolling brush 6 passes through the first scraping strip 14, the sewage on the surface of the rolling brush can be fully scraped, so that the sewage enters the sewage tank 16 through the guide plate 15, and the sewage recovery efficiency is improved.

As shown in fig. 3 and 4, one end of the first scraping strip 14 and the flow guide plate 15 close to the sewage storage chamber 12 is fixedly connected with the outer wall of the sewage storage chamber 12. When scraping the surperficial sewage of round brush 6, first scraping strip 14, in order to prevent that sewage from leaking outward from sewage water conservancy diversion room 13 both sides, can also set up side guard plate 151 at sewage water conservancy diversion room 13 both ends, enclose through side guard plate 151, first scraping strip 14, guide plate 15 and sewage reservoir room 12 outer wall and close and form the sewage water conservancy diversion room 13 that has opening A, sewage flows into sewage water conservancy diversion room 13 from opening A department, thereby make in collecting sewage, sewage can retrieve into in the sewage case 16 completely. In the embodiment shown in fig. 2, the side shield 151 and the air guide plate 15 are integrally formed, thereby further improving the sealing property.

As shown in fig. 5 and 6, at least one flow guide pipe 182 is further disposed in the sewage storage chamber 12, one end B1 of the flow guide pipe 182 extends into the inside of the sewage storage chamber 12 and is communicated with the sewage storage chamber 12, the other end B2 of the flow guide pipe 182 is communicated with the sewage guide chamber 13, and sewage enters the sewage storage chamber 12 from the sewage guide chamber 13 through the flow guide pipe 182.

During use and transportation of the surface cleaning apparatus, the waste water tank 16 may tilt with the surface cleaning apparatus, and waste water may flow back from the waste water storage chamber 12 to the waste water guide chamber 13, thereby leaking from the waste water guide chamber 13 and contaminating the floor and the roller brush 6. Therefore, the draft tube 13 is disposed at the middle position of the sewage tank 16 along the length direction of the baffle 15, and the draft tube 13 is disposed above the floating mechanism 184 along the height direction of the sewage tank 16, which includes but is not limited to the position right above the floating mechanism, and may be a position obliquely above. The main reason why the draft tube 13 is disposed above the floating mechanism 184 is that when the floating mechanism rises to an alarm position due to the liquid level in the wastewater tank (i.e., to warn that the wastewater tank needs to be cleaned and the equipment is not working), the liquid in the wastewater tank does not flow out of the draft tube. Further, when the float mechanism 184 is raised to the alarm position, the volume of the sewage in the sewage tank is V1, and V2 is larger than V1, so as to ensure that the sewage cannot directly flow out from the communication port between the sewage guide chamber 13 and the sewage storage chamber 12 when the sewage tank 16 is inclined. The volume between one side wall of the waste water tank and the adjacent guide pipe along the length direction of the guide plate is V2, that is, the volume between one end wall of the guide pipe along the length direction of the guide plate 15 and the adjacent side wall of the waste water tank is V2, and it can be understood that when one side wall of the waste water tank 16 is right above the other side wall, the water level in the waste water tank is lower than the guide pipe 13, especially lower than the water outlet of the guide pipe. Thus, the sewage in the sewage tank can be ensured not to overflow the sewage tank through the flow guide pipe 13 in the process of cleaning the sewage tank by a user. Further, the water outlet of the flow guide pipe 13 is positioned at one end close to the rear wall of the sewage tank, the distance between the water outlet of the flow guide pipe and the rear wall of the sewage tank is 1-10mm, and the smaller the distance between the water outlet of the flow guide pipe and the rear wall of the sewage tank is, the smaller the probability of water leakage in the process of cleaning the sewage tank is.

By the arrangement of the long and narrow flow guide pipe 182, when the sewage tank 16 is inclined, the sewage cannot directly flow out from the communication port between the sewage guide chamber 13 and the sewage storage chamber 12, so that the leakage of a large amount of sewage can be prevented. In this embodiment, only one flow guide pipe 182 is provided to further reduce the leakage of the sewage. In order to facilitate the sewage to enter the flow guide pipe 182 from the sewage guide chamber 13, the flow guide pipe 182 is disposed at the middle position of the sewage guide chamber 13 in the length direction, and the flow guide pipe 182 and the sewage guide chamber 13 are disposed obliquely, as shown in fig. 6, the overall height of the flow guide pipe 182 and the sewage guide chamber 13 decreases from the end B2 to the end B1. In addition, a blocking plate 183 (see fig. 4) is further disposed at a communication position between the draft tube 182 and the sewage guide chamber 13, and the blocking plate 183 can effectively block solid waste, hair, and other floccules on the roller brush 6 from entering the draft tube 182, thereby preventing blockage.

As shown in fig. 5, in the present embodiment, a floating mechanism 184 for detecting the sewage level is further disposed in the sewage storage chamber 12, and the floating mechanism 184 includes a base 185 and a floating block 186; the base 185 is fixedly attached to the waste storage chamber 12 and the slider 186 is hinged to the base 185. After a long period of use, a large amount of sewage accumulates in the sewage tank 16, causing the sewage level to rise, so that the floating piece 186 floats up along with the liquid level. In the embodiment not shown in the drawings, the cleaning head 4 is provided with an inductor, the floating block 186 is provided with an induction terminal, and when the floating block 186 rises to a certain height, the induction terminal on the floating block 186 reaches an induction area of the inductor, so that a control system on the surface cleaning equipment is matched to send a signal to a user to remind the user to pour the sewage tank 16 in time. An openable and closable seal cover 187 is provided on a side wall of the sewage tank 16, and sewage can be poured out of the sewage tank 16 by opening the seal cover 187.

As shown in fig. 4 and 3, an accommodating space 181 is formed between one side of the sewage storage chamber 12 close to the rolling brush 6 and the lower side of the sewage guide chamber 13, and a garbage can 17 for collecting solid garbage can be placed in the accommodating space 181. In this embodiment, a second scraping strip 18 for scraping off the garbage is further disposed below the flow guide plate 15 on the sewage guide chamber 13, when the surface of the rolling brush 6 rotates to the second scraping strip 18, the second scraping strip 18 can scrape off the garbage on the surface of the rolling brush 6, and the scraped garbage can fall into a garbage bin 17 below the sewage guide chamber 13 for collection. The second wiper strip 18 is preferably provided with a saw-toothed shape comprising a plurality of teeth and tooth spaces distributed at regular intervals. Therefore, the garbage on the surface of the rolling brush 6 can be scraped, and can not be scraped together with the sewage, so that the garbage can be recovered into the garbage can 17, the sewage can be recovered into the sewage can 16, and the effect of dry-wet separation is achieved.

In the present embodiment, as shown in fig. 4 and 5, the waste water tank 16 is composed of a bottom case 188 and a cover plate 189 fixed on the bottom case 188, and the waste water storage chamber 12 and the waste water diversion chamber 13 are both disposed on the bottom case 188, so that the internal structure of the waste water tank 16 can be easily manufactured. At least two grooves 190 recessed in the surface of the cover 189 are formed at the top of the cover 189, and the sump 16 can be easily taken by a user by providing the grooves 190, thereby facilitating the installation and removal of the sump on the cleaner head 4.

The implementation principle of the embodiment is as follows: during cleaning, the roller brush 6 is rotated to clean the surface to be cleaned on the floor. When the surface of the rolling brush 6 rotates to the position of the second scraping strip 18, the second scraping strip 18 can scrape the garbage on the surface of the rolling brush 6, and the scraped garbage falls into the garbage bin 17 to be collected. The surface of the rolling brush 6 continues to rotate, passes through the guide plate 15 and then reaches the first scraping strip 14, and the first scraping strip 14 can scrape off the sewage on the surface of the rolling brush 6; the scraped sewage enters the sewage guide chamber 13 along the guide plate 15, and then enters the sewage storage chamber 12 through the guide pipe 182 for storage.

The above-mentioned embodiments only represent several embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention.
