Referring to fig. 1, an embodiment of the present application provides a floor brush assembly 100 including a first housing 20, a roller brush 30, and a scraper 40. The roller brush 30 is rotatably provided in the first housing 20, and one end of the scraping member 40 is fixedly provided, and the other end is provided facing the roller brush 30 and is maintained in contact with the outer surface of the roller brush 30 during rotation of the roller brush 30, thereby brushing the outer surface of the roller brush 30. The floor brush assembly 100 is configured to form a first flow path in which liquid can flow to the roller brush 30 and a second flow path in which liquid can flow to the scraper 40. With the scraper 40 disposed facing the roller brush 30, the liquid in the second flow path continues to flow past the roller brush 30 after flowing toward the scraper 40, thereby cleaning both the roller brush 30 and the scraper 40.
Thus, by providing two liquid supply flow paths, when the first flow paths are communicated, liquid can be sprayed to the rolling brush 30 independently, so that the cleaning of the ground or the cleaning function of the rolling brush 30 independently can be realized. When the second flow paths are communicated, self-cleaning of the scraping elements 40 and the rolling brush 30 can be realized at the same time, so that the defect that the scraping elements 40 are not cleaned by only cleaning the rolling brush 30 when the conventional floor brush assembly 100 is self-cleaned is overcome, and the cleaning effect is better and comprehensive.
It can be appreciated that in practical applications, the first flow path or the second flow path may be selectively opened according to actual requirements, so as to implement different functions.
In one embodiment, the floor brush assembly 100 further includes a reversing valve assembly 10, the reversing valve assembly 10 being configured to switch between the first flow path and the second flow path. When the reversing valve apparatus 10 controls the first flow path to open, the second flow path is closed. When the reversing valve apparatus 10 controls the second flow path to open, the first flow path is closed. Thereby realizing the reversing function of the first flow path and the second flow path.
Specifically, referring to fig. 2, the reversing valve apparatus 10 includes a second housing 11 having a liquid inlet 111, a first outlet 112, and a second outlet 113, and a movable member 12 mounted in the second housing 11 and configured to be reciprocally movable in an axial direction of the second housing 11. Wherein the movable member 12 has a first position and a second position in the second housing 11, and when the movable member 12 is in the first position, the liquid inlet 111 communicates with the first outlet 112 to form a first flow path, i.e. the liquid entering the second housing 11 from the liquid inlet 111 can flow out through the first outlet 112 and flow to the roller brush 30. When the movable member 12 is in the second position, the liquid inlet 111 communicates with the second outlet 113 to form a second flow path, i.e., the liquid that has entered the second housing 11 from the liquid inlet 111 can flow out through the second outlet 113 and toward the scraper 40.
In this way, by switching the state of the movable element 12, different liquid passage communication between the first passage and the second passage is realized. So as to select according to the actual use requirement. The movable member 12 is switched to the first position and the liquid is sprayed directly onto the roller brush 30, and the movable member 12 is switched to the second position and the liquid is sprayed directly onto the scraping member 40.
It will be appreciated that by providing the reversing valve assembly 10, the liquid flow to the roller brush 30 can be switched directly to the scraper 40, thereby performing a self-cleaning operation of the roller brush 30 and the scraper 40. Thus, the water pump is used as a power source for the flow of the liquid in the first flow path and the second flow path. The original device in the floor washing system of the rolling brush 30 can be directly used without being additionally arranged, so that the floor washing system is simple in structure.
In one embodiment, referring to fig. 2, the reversing valve apparatus 10 further includes an elastic member 13, and opposite ends of the elastic member 13 are respectively connected to the second housing 11 and the movable member 12. Wherein when the movable member 12 is in the second position, the elastic member 13 elastically deforms to accumulate an elastic restoring force capable of switching the movable member 12 from the second position to the first position. Thereby, the automatic switching of the movable member 12 from the second position to the first position is achieved by the provision of the elastic member 13, i.e., the automatic switching between the second flow path formed between the second outlet 113 and the liquid inlet 111 and the first flow path formed between the first outlet 112 and the liquid inlet 111 can be achieved.
Specifically, the elastic member 13 may be a coil spring, one end of which abuts against the second housing 11, and the other end of which abuts against the movable member 12, and the movable member 12 moves toward one side near the elastic member 13 to compress the elastic member 13 to reach the second position. The elastic restoring force accumulated by the elastic member 13 directly drives the movable member 12 to move toward the side away from the elastic member 13 to switch to the first position, as the urging force acting on the movable member 12 is canceled.
In one embodiment, referring to fig. 2, the movable member 12 includes a first end 121 and a second end 122 disposed opposite to each other along an axial direction of the second housing 11, two ends of the elastic member 13 are abutted between the second housing 11 and the first end 121, and the second end 122 is assembled at an end of the second housing 11 away from the elastic member 13. When the movable member 12 is in the second position, the second end 122 closes the first outlet 112 and compresses the resilient member 13, at which point the second outlet 113 is opened. When the movable member 12 is at the first position, the elastic member 13 elastically restores and drives the first end 121 to move to close the second outlet 113, and at this time, the first outlet 112 is opened.
Thus, by exerting a force on the second end 122, the moveable member 12 is controlled to the second position such that the second end 121 closes the first outlet 112, while the second outlet 113 is in communication with the second flow path between the liquid inlet 111. By canceling the force applied to the second end 122, the movable member 12 is controlled to the first position by the elastic restoring force of the elastic member 13 so that the first end 121 closes the two outlets 113, and at this time, the first flow path between the first outlet 112 and the liquid inlet 111 communicates, thus completing the switching of the first flow path and the second flow path.
It will be appreciated that the movable member 12 moves reciprocally in the second housing 11 in the axial direction of the second housing 11, indicating that both the first end 121 and the second end 122 are in position, one of the second outlet 113 and the first outlet 112 is blocked by the movement of the positions of the first end 121 and the second end 122, and the other is released, thereby communicating with one of the first flow path and the second flow path.
In one embodiment, referring to fig. 2, the moveable member 12 further includes a connecting section 123, the connecting section 123 being connected between the first end 121 and the second end 122. When the second end 122 is acted on, the first end 121 is driven to move synchronously by the connecting section 123. When the first end 121 receives elastic restoring force, the second end 122 is driven to move synchronously by the connecting section 123. The first end 121, the second end 122, the connecting section 123 and the first housing 20 together define a communication cavity surrounding the connecting section 123, and the first outlet 112 and the second outlet 113 are both communicated with the liquid inlet 111 through the communication cavity.
In this way, in practical application, the liquid inlet 111 is kept in a normally-open state with the communication cavity, and the first outlet 112 and the second outlet 113 are switched to communicate with the communication cavity, so that a first flow path or a second flow path is formed in the communication cavity, and a communication space is provided for the flow of liquid, so that the switching of the liquid paths is completed.
Further, the second housing 11 may be configured as a hollow cylinder, the movable member 12 and the elastic member 13 are assembled inside the second housing 11, and the diameter of the first end 121 and the second end 122 is larger than the diameter of the connecting section 123 in the radial direction of the cylindrical section of the second housing 11, so that a ring-shaped circulation cavity is formed at the outer periphery of the connecting section 123.
In other embodiments, the second housing 11 may be provided with other shapes, and accordingly, the shape and size of the movable member 12 may need to be adaptively changed, so as to complete the switching between the first flow path and the second flow path.
In one embodiment, referring to fig. 2, the reversing valve apparatus 10 further includes a sealing ring 15, at least one sealing ring 15 is sleeved between the second end 122 and the second housing 11, and between the first end 121 and the second housing 11, and the sealing ring 15 is used for sealing an assembly gap between the first end 121 and the second housing 11, so as to ensure assembly tightness and avoid leakage caused by the reversing valve apparatus 10.
Specifically, the first end 121 and/or the second end 122 are provided with mounting grooves 1221 along the outer circumference, and the sealing rings 15 are correspondingly assembled in the mounting grooves 1221, so as to provide positioning positions for mounting the sealing rings 15, and make the mounting more standard.
In one embodiment, the scraping element 40 is configured to apply a force to the roller brush 30 to thereby brush the outer surface of the roller brush 30. As for the specific structure of the scraping member 40, a scraping plate, a scraping bar or other shaped structure having one end in contact with the rolling brush 30 may be provided to scrape the outer surface of the rolling brush 30, thereby scraping the excessive moisture and garbage on the rolling brush 30. The scraping element 40 is specifically configured and the application is not limited herein.
In one embodiment, the floor brush assembly 100 further includes an action plate 50 mounted to the first housing 20, the action plate 50 having a first water jet 51 and a second water jet 52, the first water jet 51 opening toward the roller brush 30 and the second water jet 52 opening toward the scraper 40. The first outlet 112 is in communication with the first water jet 51 via a conduit and the second outlet 113 is in communication with the second water jet 52 via a conduit. As such, liquid in the first flow path flows through the conduit between the first outlet 112 and the first water jet 51 to the first water jet 51 toward the roller brush 30, and liquid in the second flow path flows through the conduit between the second outlet 113 and the second water jet 52 to the second water jet 52 toward the scraper 40.
In accordance with another aspect of the present application, referring to fig. 3, there is also provided a cleaning apparatus for cleaning a floor surface. The cleaning apparatus includes a charging stand 200 and the floor brush assembly 100 described in any of the above embodiments, the floor brush assembly 100 being used to perform a cleaning operation on a floor surface.
When the cleaning device is in the second mode, the floor brush assembly 100 is clamped in the charging stand 200 and drives the movable member 12 to be in the second position, and at this time, the second flow path is communicated, and the liquid entering the communicating cavity through the liquid inlet 111 flows to the second water spraying port 52 through the second outlet 113 to spray water to the scraping member 40. When the cleaning device is in the first mode, the floor brush assembly 100 is separated from the charging seat 200 and the movable member 12 is driven to be switched to the first position, at this time, the first flow path is communicated, and the liquid entering the communicating cavity through the liquid inlet 111 flows to the first water spraying port 51 through the first outlet 112 so as to be sprayed to the rolling brush 30, thereby realizing the water spraying to the rolling brush 30 and the scraping member 40, and realizing the different requirements of the rolling brush 30 and the scraping member 40 respectively.
Specifically, the charging stand 200 has a protrusion 210, and when the cleaning device is in the second mode, the protrusion 210 abuts against the movable member 12 and drives the movable member 12 to move from the first position to the second position. Thus, by assembling the power seat and the floor brush assembly 100, automatic adjustment of the position of the movable member 12 is achieved. When the brush assembly 100 is placed on the charging stand 200, the movable member 12 is driven by the protrusion 210 to move from the second position to spray the scraper 40. When the cleaning device is separated from the charging stand 200, the movable member 12 automatically returns to the first position, thereby spraying liquid to the roller brush 30.
In one embodiment, charging stand 200 has a flushing tank open to floor brush assembly 100. When the cleaning apparatus is in the second mode, the roller brush 30 is at least partially positioned in the flushing tank and is controlled to spin, and liquid flowing in the second flow path to the scraper 40 flows through the roller brush 30 and into the flushing tank. With the rotation of the rolling brush 30, the outer surface of the rolling brush 30 is stained with the liquid in the flushing tank, thereby further improving the self-cleaning effect of the rolling brush 30.
Alternatively, the liquid provided by the first flow path and the second flow path may be water or a cleaning agent.
