Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and in particular to a cleaning floor brush, a cleaning device and a cleaning system. Background Art

[0002] Currently, for the double roller brush cleaning equipment on the market, the floor brush part has dual air ducts with a larger front and a smaller rear. During use, the suction of the dual air ducts is dispersed, resulting in insufficient suction in the front air duct and poor cleaning. When the floor brush works backwards, the rear air duct is easily blocked due to limitations such as small diameter and low suction, and water reflux is obvious. This forms a fatal flaw in the double roller brush dual air duct cleaning equipment, which greatly affects the user experience.

[0003] For example, the Chinese patent with the announcement number CN217592737U discloses a cleaning device with an air duct and a floor scrubber with the same, wherein the distance of the cleaning airflow of the cleaning device from the front suction port through the front air duct to the converging air duct is shorter than the distance of the cleaning airflow of the cleaning device from the rear suction port through the rear air duct to the converging air duct. The front roller brush is the main cleaning roller brush, and the rear roller brush is the auxiliary cleaning roller brush, and the substances absorbed by the front air duct will be more than those absorbed by the rear air duct. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a cleaning brush, a cleaning device and a cleaning system.

[0005] The embodiment of the present application adopts the following technical solution: a cleaning brush, comprising:

[0006] Housing components;

[0007] A first rolling brush, which is arranged at the front end of the housing assembly and can roll in contact with the ground;

[0008] A second roller brush, which is arranged at the rear end of the housing assembly and can roll in contact with the ground;

[0009] A first air duct, one end of which is close to the first roller brush and connected to the outside;

[0010] A second air duct, one end of which is close to the second roller brush and communicates with the outside;

[0011] A third air duct, one end of which is close to the other end of the first air duct and the other end of the second air duct, and the other end of the third air duct is connected to the main assembly of the cleaning device;

[0012] An air duct conversion member is arranged at the intersection of the first air duct, the second air duct and the third air duct. When the cleaning brush moves forward, the air duct conversion member moves around the first direction to block the second air duct and connect the first air duct with the third air duct, so that dirt on the ground enters the cleaning brush through the first air duct and the third air duct; when the cleaning brush moves backward, the air duct conversion member moves around the second direction to block the first air duct and connect the second air duct with the third air duct, so that dirt on the ground enters the cleaning brush through the second air duct and the third air duct;

[0013] The first direction is opposite to the second direction.

[0014] When the local brush works forward, the air duct conversion part moves to connect the first air duct and the third air duct in front and close the second air duct at the back. When the local brush works backward, it connects the second air duct and the third air duct at the back and closes the first air duct in front. The air duct is switched by the movement of the air duct conversion part, thereby ensuring that a strong suction force of a single air duct is formed during the working process, and reducing the air duct switching time and the probability of clogging the suction port, thereby solving the defects of the double roller brush in the prior art, and completing a true double roller brush, a double air duct front and back suction cleaning system, reducing user usage restrictions, and greatly improving user experience.

[0015] In some embodiments, a first rotating shaft is provided at one end of the air duct conversion member, and a second rotating shaft is provided at the other end of the air duct conversion member; the middle part of the air duct conversion member is an arc-shaped plate, and there are sealing plates at both ends of the arc-shaped plate; when the air duct conversion member blocks the second air duct, the outer plate surface of the arc-shaped plate faces the second air duct; when the air duct conversion member blocks the first air duct, the outer plate surface of the arc-shaped plate faces the first air duct.

[0016] The blocking switching of the first air duct or the second air duct is realized by the arc plate, and the switching process can be smoothly completed by the arc plate.

[0017] In some embodiments, a scraper is provided on the outer plate surface of the arc-shaped plate to reduce the friction between the air duct conversion component and the outer shell component forming the first air duct or the second air duct when the air duct conversion component blocks the first air duct or the second air duct.

[0018] In some embodiments, the inner plate surface of the curved plate is a smooth curved surface, and when the first air duct is connected to the third air duct, the smooth curved surface can smoothly connect the first air duct and the third air duct; when the second air duct is connected to the third air duct, the smooth curved surface can smoothly connect the second air duct and the third air duct.

[0019] The inner plate surface of the arc plate is a smooth arc surface, so that when the first air duct or the second air duct is connected to the third air duct, dirt is not easily accumulated at the connection between the first air duct or the second air duct and the third air duct.

[0020] In some embodiments, the first rotating shaft or the second rotating shaft is connected to a driving member, and a visualization window is also provided on the first rotating shaft or the second rotating shaft connected to the driving member for observing the connection status of the driving member and the first rotating shaft or the second rotating shaft.

[0021] In some embodiments, the housing assembly includes an upper housing assembly, a lower housing assembly, and a floor brush head, wherein the upper housing assembly is disposed on the lower housing assembly, and the lower housing assembly is disposed on the floor brush head;

[0022] The cleaning floor brush also includes a fixing seat, which is detachably arranged on the floor brush head and is hinged to the first rotating shaft and the second rotating shaft of the air duct conversion component so that the air duct conversion component can rotate relative to the fixing seat.

[0023] By arranging the air duct conversion component on the fixing seat, and the fixing seat being detachably arranged on the housing component, the air duct conversion component can be quickly disassembled.

[0024] In some embodiments, both the first rotating shaft and the second rotating shaft are provided with an annular protrusion around the axis of the first rotating shaft and the second rotating shaft;

[0025] Both ends of the fixing seat are provided with grooves respectively matched with the annular protrusions. The annular protrusions are placed in the grooves and rotate under the guidance of the grooves.

[0026] Through the cooperation of the annular protrusion and the groove, good positioning and guiding of the rotation of the air duct switching member can be achieved, so that the air duct switching member can rotate stably to achieve the switching of the connection between the first air duct and the second air duct and the third air duct.

[0027] In some embodiments, a first soft scraping strip is disposed at one end of the first air duct close to the first rolling brush; a second soft scraping strip is disposed at one end of the second air duct close to the second rolling brush;

[0028] The first soft scraper strip and the second soft scraper strip are in contact with the ground.

[0029] The soft scraper bar is in contact with the ground and can scrape away water stains and garbage sucked in by the roller brush when cleaning the ground.

[0030] The present application also provides a cleaning device, including the cleaning brush as described in any one of the above embodiments, and also including a main body component, wherein the main body component includes:

[0041] The embodiment of the present application further provides a cleaning system, including a base station and a cleaning device, wherein the base station includes a fan and a hot air duct, and the hot air duct has a first hot air outlet and a second hot air outlet;

[0042] When the cleaning device is placed on the base station and is drying, the air duct conversion part of the cleaning floor brush moves to a preset position, and the fan and the sub-machine component provide suction so that the first air duct and the second air duct of the cleaning floor brush are connected to the third air duct, thereby enabling the fan to blow out the hot air through the first hot air outlet and the second hot air outlet, and blow the hot air to the first air duct, the second air duct and the third air duct of the cleaning floor brush through the hot air duct.

[0043] The beneficial effects of the embodiments of the present application are:

[0044] When the local brush works forward, the air duct conversion part moves to connect the first air duct and the third air duct in front and close the second air duct at the back.

DETAILED DESCRIPTION

[0065] Various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0066] It should be understood that various modifications may be made to the embodiments of the present application. Therefore, the above description should not be considered as limiting, but only as an example of an embodiment. Other modifications within the scope and spirit of the present application will occur to those skilled in the art.

[0067] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present application and, together with the general description of the present application given above and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0068] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0069] It should also be understood that although the present application has been described with reference to some specific examples, those skilled in the art will be able to readily implement many other equivalent forms of the present application.

[0070] The above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

[0071] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present application. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0072] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0073] For the cleaning equipment with switchable sewage suction air ducts currently on the market, the floor brush part of the cleaning equipment is equipped with a driving gear connected to an external gear, and the outer wall is rotatably connected to a number of supporting gears that mesh with the external gear, so that the switching pipe rotates in a vertical direction to switch the front and rear sewage suction air ducts. The complex transmission structure of the driving gear module will greatly increase the cost of the product. In addition, the slow switching of the air duct during long-term use of the floor scrubber is prone to accumulation at the sewage suction port, resulting in varying degrees of blockage when the switching part fails to switch. The above structure greatly reduces the life of the driving motor and the cleaning performance of the product. It is difficult for users to clear the blockage, which is time-consuming and laborious.

[0074] The present application provides a cleaning brush 6, such as Fig.11 , Figure 2 , Figure 3 and Figure 4 As shown, the cleaning brush 6 comprises a housing assembly, a first roller brush 7, a second roller brush 8, a first air duct 6.3.2, a second air duct 6.3.3, a third air duct 6.3.4 and an air duct conversion member 6.4.

[0075] The housing assembly serves as the installation base for other installation structural components. The housing assembly provides installation space or installation position for the installation of other structural components.

[0076] The first roller brush 7 is arranged at the front end of the housing assembly and can roll in contact with the ground. The second roller brush 8 is arranged at the rear end of the housing assembly and can roll in contact with the ground. The rolling of the first roller brush 7 and the second roller brush 8 can realize the cleaning of the ground waiting for cleaning.

[0077] One end of the first air duct 6.3.2 is close to the first roller brush 7 and communicates with the outside. One end of the second air duct 6.3.3 is close to the second roller brush 8 and communicates with the outside. There is a certain gap between one end of the first air duct 6.3.2 and the first roller brush 7, and there is also a certain gap between one end of the second air duct 6.3.3 and the second roller brush 8, so that dirt on the ground can enter the first air duct 6.3.2 through the gap between one end of the first air duct 6.3.2 and the first roller brush 7, or the dirt on the ground can enter the second air duct 6.3.3 through the gap between one end of the second air duct 6.3.3 and the second roller brush 8.

[0078] One end of the third air duct 6.3.4 is close to the other end of the first air duct 6.3.2 and the other end of the second air duct 6.3.3, and the other end of the third air duct 6.3.4 is connected to the main component of the cleaning device, so that the dirt passing through the first air duct 6.3.2 or the second air duct 6.3.3 can enter the third air duct 6.3.4, and then enter the main component of the cleaning device for collection of the dirt.

[0079] The air duct conversion member 6.4 is arranged at the intersection of the first air duct 6.3.2, the second air duct 6.3.3 and the third air duct 6.3.4. When the cleaning brush 6 moves forward, the air duct conversion member 6.4 moves around the first direction to block the second air duct 6.3.3 and connect the first air duct 6.3.2 with the third air duct 6.3.4, so that the dirt on the ground enters the cleaning brush 6 through the first air duct 6.3.2 and the third air duct 6.3.4. When the cleaning brush 6 moves backward, the air duct conversion member 6.4 moves around the second direction to block the first air duct 6.3.2 and connect the second air duct 6.3.3 with the third air duct 6.3.4, so that the dirt on the ground enters the cleaning brush 6 through the second air duct 6.3.3 and the third air duct 6.3.4. The first direction is opposite to the second direction. That is, the air duct conversion part 6.4 can change its position according to the movement direction of the cleaning brush 6, so that the cleaning brush 6 maintains the single air duct operation, thereby ensuring the formation of a strong single air duct suction during the operation, improving the utilization rate of the suction motor 2.5, and reducing the air duct change time and the probability of clogging of the suction port, thereby solving the defects of the double roller brush in the existing cleaning brush 6, and realizing the double roller brush and double air ducts that can switch back and forth to suck dirt, greatly improving the user experience. Here, the single air duct refers to the air duct composed of the first air duct 6.3.2 and the third air duct 6.3.4 when the cleaning brush 6 moves forward; or refers to the air duct composed of the second air duct 6.3.3 and the third air duct 6.3.4 when the cleaning brush 6 moves backward.

[0080] It should be noted that forward movement refers to directions such as the front, left front and right front, while backward movement refers to directions such as the rear, left rear and right rear, rather than a single absolute front and back direction.

[0081] In the embodiment of the present application, when the cleaning floor brush 6 works forward, the air duct conversion member 6.4 is actuated to connect the first air duct 6.3.2 and the third air duct 6.3.4 in the front and close the second air duct 6.3.3 at the rear; when the floor brush works backward, the second air duct 6.3.3 and the third air duct 6.3.4 at the rear are connected and the first air duct 6.3.2 in the front is closed. The switching of the air duct is achieved through the action of the air duct conversion member 6.4, thereby ensuring that a strong suction force of a single air duct is formed during the working process, and reducing the air duct switching time and the probability of clogging of the suction port, thereby solving the defects of the double roller brush in the prior art, and completing the true double roller brush, and the double air ducts can be sucked freely from front to back for cleaning, reducing user usage restrictions, and greatly improving user experience.

[0082] In some embodiments, Figure 8 , Fig. 9 and Fig.10As shown, a first rotating shaft 6.4.2 is arranged at one end of the air duct conversion member 6.4, a second rotating shaft 6.4.3 is arranged at the other end of the air duct conversion member 6.4, the middle part of the air duct conversion member 6.4 is an arc plate 6.4.1, and blocking plates are arranged at both ends of the arc plate 6.4.1, and the blocking plates can be blocked at both ends of the arc plate 6.4.1, and the first rotating shaft 6.4.2 and the second rotating shaft 6.4.3 can be arranged on the blocking plates at both ends of the arc plate 6.4.1 respectively. When the air duct conversion member 6.4 blocks the second air duct 6.3.3, the outer plate surface of the arc plate 6.4.1 faces the second air duct 6.3.3; when the air duct conversion member 6.4 blocks the first air duct 6.3.2, the outer plate surface of the arc plate 6.4.1 faces the first air duct 6.3.2. The blocking switch of the first air duct 6.3.2 or the second air duct 6.3.3 is realized by the arc plate 6.4.1, and the switching process can be smoothly completed by the arc plate 6.4.1.

[0083] In addition, a scraper 6.4.4 may be provided on the outer plate surface of the arc plate 6.4.1 to reduce the friction between the air duct conversion member 6.4 and the outer shell component forming the first air duct 6.3.2 or the second air duct 6.3.3 when the air duct conversion member 6.4 blocks the first air duct 6.3.2 or the second air duct 6.3.3.

[0084] like Figure 3 and Figure 4 As shown, from the cross-section of the cleaning brush 6, the A duct conversion node of the arc plate 6.4.1 is connected to the lower part of the first duct 6.3.2, and the B duct conversion node is connected to the side of the third duct 6.3.4 close to the second duct 6.3.3. At this time, the horizontal position of the B duct conversion node is higher than that of the A duct conversion node, and at the same time, the C scraper 6.4.4 node moves to one side of the second duct 6.3.3 (to scrape the tiny particles in the first duct 6.3.2 to the second duct 6.3.3 to be sucked away when moving in the second direction), the first duct 6.3.2 is opened, and the second duct 6.3.3 is closed to complete the cleaning during forward movement. When moving in the second direction, the B duct conversion node is connected to the lower part of the second duct 6.3.3, and the A duct conversion node is connected to the side of the third duct 6.3.4 close to the second duct 6.3.3. At this time, the horizontal position of the A duct conversion node is higher than that of the B duct conversion node, and the D scraper 6.4.4 node moves to one side of the first duct 6.3.2 (to scrape the tiny particles in the second duct 6.3.3 to the first duct 6.3.2 to be sucked away when moving in the first direction). The second duct 6.3.3 is opened, and the first duct 6.3.2 is closed to complete the cleaning during the backward movement.

[0085] In some embodiments, the inner plate surface of the curved plate 6.4.1 is a smooth curved surface. When the first air duct 6.3.2 is connected to the third air duct 6.3.4, the smooth curved surface can smoothly connect the first air duct 6.3.2 and the third air duct 6.3.4. When the second air duct 6.3.3 is connected to the third air duct 6.3.4, the smooth curved surface can smoothly connect the second air duct 6.3.3 and the third air duct 6.3.4. The inner plate surface of the curved plate 6.4.1 is a smooth curved surface, so that when the first air duct 6.3.2 or the second air duct 6.3.3 is connected to the third air duct 6.3.4, the connection between the first air duct 6.3.2 or the second air duct 6.3.3 and the third air duct 6.3.4 is not easy to accumulate dirt.

[0086] That is, the curvature of the curved surface formed by the inner plate surface of the curved plate 6.4.1 corresponds to the curvature formed by the inner cavity of the first air duct 6.3.2, the second air duct 6.3.3, and the third air duct 6.3.4, ensuring that the first air duct 6.3.2 and the second air duct 6.3.3 can smoothly transition the dirty garbage at the air duct conversion part 6.4 after the air duct conversion. The outer curved surface structure of the curved plate 6.4.1 is provided with a scraper 6.4.4 structure to reduce the friction during the movement while ensuring the sealing, reduce the friction area of ​​the air duct conversion part 6.4, ensure the smooth movement and sealing of the air duct conversion part 6.4, and the scraper 6.4.4 is attached to the tiny particles remaining in the outer slideway, which will be sucked clean during the next air duct conversion, effectively preventing blockage, so that the first air duct 6.3.2 and the second air duct 6.3.3 have a better sealing effect when they are closed.

[0087] In some embodiments, Figure 5 , Figure 6 and Figure 7 As shown, the first rotating shaft 6.4.2 or the second rotating shaft 6.4.3 is connected to the driving member 6.5, and a visualization window 6.4.5 is also provided on the first rotating shaft 6.4.2 or the second rotating shaft 6.4.3 connected to the driving member 6.5, so as to observe the connection between the driving member 6.5 and the first rotating shaft 6.4.2 or the second rotating shaft 6.4.3. The driving member 6.5 can be a motor, and the motor can be a stepping motor capable of forward and reverse rotation. The visualization window 6.4.5 is convenient for observing whether the driving member 6.5 is installed in place, and is also convenient for disassembly.
