Floor brush assembly and cleaning device

Abstract

The present application relates to a floor brush assembly and a cleaning device, specifically including a first housing, a rotary brush, and a scraping member. The rotary brush is rotatably disposed within the first housing. One end of the scraping member is fixedly arranged, and the other end faces the rotary brush and remains in contact with the outer surface of the rotary brush during the rotation of the rotary brush, thereby scraping the outer surface of the rotary brush. Moreover, the floor brush assembly is configured to form a first flow path and a second flow path. The liquid within the first flow path can flow towards the rotary brush, and the liquid within the second flow path can flow towards the scraping member. Thus, by providing two liquid supply flow paths, when the first flow path is connected, it is possible to achieve spraying liquid onto the rotary brush alone, thereby realizing the cleaning of the ground or the cleaning function of the rotary brush alone. When the second flow path is connected, it is possible to simultaneously achieve the self-cleaning of the scraping member and the rotary brush, thereby making up for the defect that only the rotary brush is cleaned and the scraping member is not cleaned during the self-cleaning of the traditional floor brush assembly, making the cleaning effect more comprehensive.

[0043] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0044] In the present application, unless otherwise clearly specified and limited, the terms "mounted", "connected", "coupled", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0045] In the present application, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature.

[0046] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0047] Referring to Figure 1 , an embodiment of the present application provides a floor brush assembly 100, including a first housing 20, a roller brush 30 and a scraping member 40. The roller brush 30 is rotatably disposed in the first housing 20. One end of the scraping member 40 is fixedly arranged, and the other end faces the roller brush 30 and remains in contact with the outer surface of the roller brush 30 during the rotation of the roller brush 30, so as to brush the outer surface of the roller brush 30. Moreover, the floor brush assembly 100 is configured to form a first flow path and a second flow path. The liquid in the first flow path can flow to the roller brush 30, and the liquid in the second flow path can flow to the scraping member 40. Since the scraping member 40 faces the roller brush 30, the liquid flowing into the scraping member 40 in the second flow path will continue to flow through the roller brush 30, thereby cleaning the roller brush 30 and the scraping member 40 at the same time.

[0048] In this way, by providing two liquid supply flow paths, when the first flow path is connected, the roller brush 30 can be sprayed with liquid alone, so as to realize the cleaning of the ground or the cleaning function of the roller brush 30 alone. When the second flow path is connected, the self-cleaning of the scraping member 40 and the roller brush 30 can be realized at the same time, thus making up for the defect that only the roller brush 30 is cleaned and the scraping member 40 is not cleaned during the self-cleaning of the traditional floor brush assembly 100, and making the cleaning effect more comprehensive.

[0049] It can be understood that in practical applications, the first flow path or the second flow path can be selected to be opened according to actual needs, so as to realize different functions.

[0050] In one of the embodiments, the floor brush assembly 100 further includes a reversing valve device 10, and the reversing valve device 10 is used to switch between the first flow path and the second flow path. When the reversing valve device 10 controls the first flow path to be opened, the second flow path is closed. When the reversing valve device 10 controls the second flow path to be opened, the first flow path is closed. Thus, the reversing function of the first flow path and the second flow path is realized.

[0051] Specifically, referring to Figure 2, the reversing valve device 10 includes a second housing 11 and a movable member 12. The second housing 11 has a liquid inlet 111, a first outlet 112, and a second outlet 113. The movable member 12 is installed within the second housing 11 and is configured to be reciprocally movable along the axial direction of the second housing 11. Among them, the movable member 12 has a first position and a second position within the second housing 11. 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, that is, at this time, 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, that is, at this time, the liquid entering the second housing 11 from the liquid inlet 111 can flow out through the second outlet 113 and flow to the scraping member 40.

[0052] In this way, by switching the state of the movable member 12, different liquid path connections between the first flow path and the second flow path are achieved. Thus, it can be selected according to actual usage requirements. When the movable member 12 is switched to the first position, the liquid is directly sprayed onto the roller brush 30; when the movable member 12 is switched to the second position, the liquid is directly sprayed onto the scraping member 40.

[0053] It can be understood that by setting the reversing valve device 10, the liquid flowing to the roller brush 30 can be directly switched to flow to the scraping member 40, thereby performing the self-cleaning operation of the roller brush 30 and the scraping member 40. In this way, as the power source of the liquid flowing in the first flow path and the second flow path, the water pump. The original device in the floor washing system of the roller brush 30 can be directly borrowed without additional installation, thus making the structure simple.

[0054] In one embodiment, refer to Figure 2 , the reversing valve device 10 further includes an elastic member 13. The opposite ends of the elastic member 13 are respectively connected to the second housing 11 and the movable member 12. Among them, when the movable member 12 is in the second position, the elastic member 13 undergoes elastic deformation to accumulate an elastic restoring force capable of switching the movable member 12 from the second position to the first position. Thus, through the setting of the elastic member 13, the automatic switching of the movable member 12 from the second position to the first position is achieved, that is, 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 realized.

[0055] Specifically, the elastic member 13 can be a helical spring, with one end abutting against the second housing 11 and the other end abutting against the movable member 12. The movable member 12 moving towards the side close to the elastic member 13 can compress the elastic member 13 until it reaches the second position. When the acting force on the movable member 12 is cancelled, the elastic restoring force accumulated by the elastic member 13 directly drives the movable member 12 to move towards the side away from the elastic member 13 and thus switch to the first position.

[0056] In one embodiment, referring to Figure 2 , the movable member 12 includes a first end 121 and a second end 122 that are oppositely arranged along the axial direction of the second housing 11. Both ends of the elastic member 13 abut between the second housing 11 and the first end 121, and the second end 122 is assembled at one 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 elastic member 13, and at this time the second outlet 113 is opened. When the movable member 12 is in the first position, the elastic member 13 elastically returns and drives the first end 121 to move to close the second outlet 113, and at this time the first outlet 112 is opened.

[0057] In this way, by applying a force to the second end 122, the movable member 12 is controlled to the second position, so that the second end 121 closes the first outlet 112, and at this time the second flow path between the second outlet 113 and the liquid inlet 111 is communicated. By canceling the force applied to the second end 122, under the action of the elastic restoring force of the elastic member 13, the movable member 12 is controlled to the first position so that the first end 121 closes the second outlet 113, and at this time the first flow path between the first outlet 112 and the liquid inlet 111 is communicated. In this way, the mutual switching of the first flow path and the second flow path is completed.

[0058] It can be understood that while the movable member 12 reciprocates axially in the second housing 11, it indicates that both the first end 121 and the second end 122 are moving in position. Through the movement of the positions of the first end 121 and the second end 122, one of the second outlet 113 and the first outlet 112 is blocked and the other is released, so as to connect one of the first flow path and the second flow path.

[0059] In one embodiment, referring to Figure 2 , the movable member 12 further includes a connecting section 123, and the connecting section 123 is connected between the first end 121 and the second end 122. When the second end 122 is subjected to a force, the first end 121 is driven to move synchronously through the connecting section 123. When the first end 121 is subjected to an elastic restoring force, the second end 122 is driven to move synchronously through the connecting section 123. The first end 121, the second end 122, the connecting section 123 and the first housing 20 jointly define a communication cavity surrounding the outer periphery of the connecting section 123, and both the first outlet 112 and the second outlet 113 are communicated with the liquid inlet 111 through the communication cavity.

[0060] In this way, in practical applications, the liquid inlet 111 remains in a normally open state with the communication cavity, and by switching the communication between the first outlet 112 and the second outlet 113 and the communication cavity, a first flow path or a second flow path is formed in the communication cavity, providing a communication space for the flow of the liquid, so as to complete the switching of the liquid path.

[0061] Further, the second housing 11 can be set as a hollow cylindrical shape. The movable member 12 and the elastic member 13 are assembled inside the second housing 11. And in the radial direction of the cylindrical section of the second housing 11, the diameter dimensions of the first end 121 and the second end 122 are larger than the diameter dimension of the connecting section 123, so as to form an annular flow cavity on the outer periphery of the connecting section 123.

[0062] In other embodiments, the second housing 11 can also be set as other shapes. Correspondingly, the shape and size of the movable member 12 also need to be adaptively changed to complete the switching between the first flow path and the second flow path.

[0063] In one embodiment, referring to Figure 2 , the reversing valve device 10 further includes a sealing ring 15. Between the second end 122 and the second housing 11, and between the first end 121 and the second housing 11, at least one sealing ring 15 is sleeved. The sealing ring 15 is used to seal the assembly gap between the first end 121 and between the first end 121 and the second housing 11, so as to ensure the assembly sealing performance and avoid liquid leakage caused by the reversing valve device 10.

[0064] Specifically, an installation groove 1221 is axially provided on the outer periphery of the first end 121 and / or the second end 122. The sealing rings 15 are respectively assembled in the installation grooves 1221, so as to provide a positioning position for the installation of the sealing rings 15 and make the installation more standardized.

[0065] In one embodiment, the scraping member 40 is used to apply a force to the roller brush 30 to brush the outer surface of the roller brush 30. As for the specific structure of the scraping member 40, it can be set as a scraping plate, a scraping strip or other structural forms in contact with the roller brush 30 at one end to brush the outer surface of the roller brush 30, scrape off the excess water and garbage on the roller brush 30, and achieve the scraping effect. The specific shape of the scraping member 40 is not limited in this application.

[0066] In one embodiment, the floor brush assembly 100 further includes an action plate 50 installed on the first housing 20. The action plate 50 has a first water spray port 51 and a second water spray port 52. The first water spray port 51 is opened facing the roller brush 30, and the second water spray port 52 is opened facing the scraping member 40. The first outlet 112 is communicated with the first water spray port 51 through a pipeline, and the second outlet 113 is communicated with the second water spray port 52 through a pipeline. In this way, the liquid in the first flow path flows through the pipeline between the first outlet 112 and the first water spray port 51 to the first water spray port 51 and is sprayed onto the roller brush 30, and the liquid in the second flow path flows through the pipeline between the second outlet 113 and the second water spray port 52 to the second water spray port 52 and is sprayed onto the scraping member 40.

[0067] According to another aspect of the present application, referring to Figure 3, a cleaning device is also provided for cleaning the ground. The cleaning device includes a charging base 200 and the floor brush assembly 100 described in any of the above embodiments, and the floor brush assembly 100 is used to perform a cleaning operation on the ground.

[0068] Wherein, the cleaning device has a first mode and a second mode. When the cleaning device is in the second mode, the floor brush assembly 100 is clamped in the charging base 200 and drives the movable member 12 to be in the second position. At this time, the second flow path is connected, and the liquid entering the communication cavity from the liquid inlet 111 flows through the second outlet 113 to the second water spray port 52 to spray water on the scraping member 40. When the cleaning device is in the first mode, the floor brush assembly 100 is separated from the charging base 200 and the driving movable member 12 switches to the first position. At this time, the first flow path is connected, and the liquid entering the communication cavity from the liquid inlet 111 flows through the first outlet 112 to the first water spray port 51 and then sprays onto the roller brush 30, so as to realize spraying water on the roller brush 30 and the scraping member 40, and meet the different requirements of the roller brush 30 and the scraping member 40 respectively.

[0069] Specifically, the charging base 200 has a convex portion 210. When the cleaning device is in the second mode, the convex portion 210 abuts on the movable member 12 and drives the movable member 12 to move from the first position to the second position. Thus, through the assembly of the power supply base and the floor brush assembly 100, the automatic adjustment of the position of the movable member 12 is realized. When the floor brush assembly 100 is placed on the charging base 200, the convex portion 210 drives the movable member 12 to move from the second position to the second position to spray liquid on the scraping member 40. When the cleaning device is separated from the charging base 200, the movable member 12 automatically returns to the first position, so as to spray liquid on the roller brush 30.

[0070] In one embodiment, the charging base 200 has a flushing groove opened facing the floor brush assembly 100. When the cleaning device is in the second mode, at least part of the roller brush 30 is located in the flushing groove and is controlled to rotate. The liquid flowing to the scraping member 40 in the second flow path flows through the roller brush 30 and enters the flushing groove. As the roller brush 30 rotates, the outer surface of the roller brush 30 will be contaminated with the liquid in the flushing groove, thereby further improving the self-cleaning effect of the roller brush 30.

[0071] Optionally, the liquid provided by the first flow path and the second flow path can be water or a cleaning agent.

[0072] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0073] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
