[0006] In order to achieve the above objectives, the embodiments of the present application provide the following technical solutions:

[0007] The first aspect of the embodiment of the present application provides a floor brush assembly, comprising: a water tank and a control mechanism; the water tank has an air inlet and a water outlet; the control mechanism comprises a pressure piece, a pressure seat and a first control valve, the pressure seat has a pressure chamber, the pressure piece has a pressure channel, the pressure seat is arranged on the water tank, the pressure piece is movably connected to the pressure seat so that the pressure channel is connected to the pressure chamber, the pressure chamber is connected to the air inlet, and the first control valve is arranged at the air inlet; the pressure piece is constructed to be able to move from a first position to a second position relative to the pressure seat under the action of external force, and to generate negative pressure in the pressure chamber, the generated negative pressure opens the first control valve and enters the water tank, so that the liquid in the water tank overflows through the water outlet under the action of the negative pressure.

[0008] The floor brush assembly provided in the embodiment of the present application is designed with a control mechanism, which includes a pressure piece, a pressure seat and a first control valve. The pressure seat has a pressure chamber, the pressure piece has a pressure channel, the pressure seat is arranged on the water tank, the pressure piece is movably connected to the pressure seat, the pressure channel is connected to the pressure chamber, the pressure chamber is connected to the air inlet, and the first control valve is arranged at the air inlet; the pressure piece is constructed so that under the action of external force, such as the user applies force to the pressure piece by stepping on the foot, the pressure piece can move from the first position to the second position relative to the pressure seat, and generate negative pressure in the pressure chamber. The generated negative pressure can open the first control valve, so that the negative pressure enters the water tank. In this way, the liquid in the water tank can overflow through the water outlet under the pressure of the negative pressure, thereby achieving the purpose of water discharge from the water tank, without consuming electricity, saving energy and being environmentally friendly, thereby reducing the cost of water discharge from the water tank.

[0009] In some embodiments, the control mechanism further comprises at least one elastic reset member, and the at least one elastic reset member is disposed between the water tank and the pressure member.

[0010] The elastic return member is configured to drive the pressure member to move from the second position to the first position through its own elastic force.

[0014] In some embodiments, the control mechanism further includes an elastic member, the elastic member is disposed at one end of the pressure member facing the pressurizing seat, and the elastic member has a through hole connecting the pressure channel and the pressurizing chamber.

[0015] Such an arrangement can avoid the pressure-applying member from coming into rigid contact with the pressurizing chamber when the pressure-applying member moves to the second position, thereby extending the service life of the pressure-applying member and the pressurizing chamber.

[0021] Such an arrangement increases the space of the negative pressure environment, thereby improving the reliability of driving water out of the water tank through negative pressure.

[0022] In some embodiments, the pressure member has a first limiting portion at one end away from the pressurizing seat, the water tank has a second limiting portion, one end of the elastic return member is connected to the first limiting portion, and the other end of the elastic return member is connected to the second limiting portion.

[0023] By setting in this way, the position reliability of the elastic reset member is improved by limiting the circumferential direction of the elastic reset member, thereby improving the working reliability of the control mechanism.

[0024] In some embodiments, the water tank has a receiving groove, and at least one of the second limiting portion and the installation position is disposed in the receiving groove.

[0025] Such an arrangement can improve the structural compactness of the floor brush assembly.

[0026] In some embodiments, a pressing member is further included, which is arranged at one end of the pressure member away from the pressurizing seat, and the pressing member is configured to apply a pressing force to the pressure member under external force to move the pressure member toward the pressurizing seat.

[0027] With such arrangement, the user can apply pressing force to the pressure-applying member through the pressing member, thereby improving the user's operating comfort.

[0028] In some embodiments, a first limiting structure is provided on the inner wall of the pressurizing chamber, and when the pressure member moves to the second position, the pressure member is configured to abut against the first limiting structure.

[0029] Such an arrangement improves the reliability of the moving position of the pressure member, thereby improving the reliability of water discharge from the water tank.

[0030] In some embodiments, the pressure member has a second limiting structure, and the pressure seat has a third limiting structure matching the second limiting structure at one end facing the pressure member, and when the pressure member moves to the first position, the first limiting structure and the second limiting structure are connected.

[0031] Such an arrangement can prevent the pressure-applying member and the pressure seat from being separated from or shifted from each other, thereby improving the reliability of the movable connection between the pressure-applying member and the pressure seat.

[0054] With the continuous development of science and technology and the improvement of people's living standards, new household appliances such as vacuum cleaners, floor scrubbers and other household cleaning equipment are increasingly appearing in people's lives. In the related art, the cleaning equipment may include a main unit and a floor brush assembly, the floor brush assembly includes a water tank, a roller brush assembly, a water pump and an electric control unit, the water pump is arranged in the water tank, the water tank has a water outlet facing the roller brush assembly, and the electric control unit is used to control the working state of the water pump, so that the water in the water tank is pumped through the water outlet and sprayed to the roller brush assembly, so that the roller brush assembly wet mops the ground, etc. However, in the related art, the working state of the water pump is controlled by the electric control unit, so that the water tank discharges water in a manner that consumes a lot of power and has a high equipment cost, thereby leading to a technical problem of high water tank discharge cost.

[0055] In order to solve the above problems, an embodiment of the present application provides a floor brush assembly, which is designed with a control mechanism, and the control mechanism includes a pressure piece, a pressure seat and a first control valve. The pressure seat has a pressure chamber, the pressure piece has a pressure channel, the pressure seat is arranged on the water tank, the pressure piece is movably connected to the pressure seat, the pressure channel is connected to the pressure chamber, the pressure chamber is connected to the air inlet, and the first control valve is arranged at the air inlet; the pressure piece is constructed to be under the action of external force, such as the user applies force to the pressure piece by stepping on the foot, so that the pressure piece can move from the first position to the second position relative to the pressure seat, and generate negative pressure in the pressure chamber. The generated negative pressure can open the first control valve, so that the negative pressure enters the water tank. In this way, the liquid in the water tank can overflow through the water outlet under the pressure of the negative pressure, thereby achieving the purpose of water discharge from the water tank, without consuming electricity, saving energy and protecting the environment, thereby reducing the cost of water discharge from the water tank.

[0056] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0057] An embodiment of the present application provides a floor brush assembly, which is applied to a cleaning device. The cleaning device may be a vacuum cleaner with a roller brush and a water tank, or an automatic cleaning robot, so that the roller brush can perform operations such as wet mopping the floor. The embodiment of the present application does not specifically limit the type of cleaning device.

[0058] Please refer to Figure 1As shown, the floor brush assembly 100 provided in the embodiment of the present application includes a floor brush base 110, a roller brush 120 connected to the floor brush base 110, and a water tank 130. The water tank 130 is used to store cleaning liquid, and the cleaning liquid can be water or a mixed liquid of detergent and water.

[0059] When the cleaning device is cleaning the floor, as the cleaning device moves in the forward direction, the roller brush 120 can rotate relative to the floor, and the water tank 130 discharges the cleaning liquid outward through the water outlet on the water tank 130. The cleaning liquid can be guided to the roller brush 120 through the pipeline, and the roller brush 120 rotates to clean and mop the floor, so as to achieve the purpose of cleaning the floor.

[0060] In addition, if Figure 1 As shown, the floor brush base 110 also includes a front cover 111 and a rear cover 112. When the roller brush 120 is installed on the floor brush base 110, the front cover 111 and the rear cover 112 are respectively arranged on part of the periphery of the roller brush 120 to prevent the dirty water from splashing around when the roller brush 120 moves.

[0061] In some embodiments, the floor brush assembly 100 also includes a host connector 140, so that the floor brush base 110 is connected to the host of the cleaning device through the host connector 140, and the host connector 140 can rotate relative to the floor brush base 110, so that the host connector 140 drives the host to rotate relative to the floor brush base 110 between a lying position or an upright position, so that the cleaning device can clean different areas.

[0062] In some embodiments, the floor brush assembly 100 further includes an electric control mechanism, which includes a water pump and an electric control unit, which is electrically connected to the water pump, and the water pump is disposed in the water tank 130. When the water tank 130 needs to discharge cleaning liquid, the electric control unit can control the water pump to pump water outward through the water outlet, so that the cleaning liquid is discharged to the roller brush 120, so as to achieve wet mopping of the floor. The electric control unit is, for example, a controller.

[0063] However, the electrical control unit and the water pump are electrically connected and the clean liquid in the water tank 130 is discharged through the water pump. Firstly, the cost of the electrical control unit and the water pump is relatively high. In addition, the electrical control mechanism consumes a lot of electricity when pumping water, which results in a high cost for discharging water from the water tank 130.

[0064] In order to reduce the cost of water out of the water tank 130, in the embodiment of the present application, please refer to Figures 2 to 7As shown, the floor brush assembly 100 includes a control mechanism 150, which includes a pressure member 151, a pressure seat 152 and a first control valve 153. The pressure seat 152 has a pressure chamber 1521, and the pressure member 151 has a pressure channel 1511. The pressure seat 152 is arranged on the water tank 130. The pressure member 151 is movably connected with the pressure seat 152 so that the pressure channel 1511 is connected with the pressure chamber 1521, and the pressure chamber 1521 is connected with the air inlet 131. The first control valve 153 is arranged at the air inlet 131; the pressure member 151 is constructed to move from a first position to a second position relative to the pressure seat 152 under the action of external force, and to generate negative pressure in the pressure chamber 1521. The generated negative pressure opens the first control valve 153 and enters the water tank 130, so that the liquid in the water tank 130 overflows through the water outlet under the action of negative pressure.

[0065] Among them, Figure 2 As shown in, the first control valve 153 can be, for example, a duckbill valve, that is, the first control valve 153 has a first valve port and a second valve port that are interconnected, the first valve port facing the pressurizing chamber 1521 and being connected to the pressurizing chamber 1521, the second valve port facing the water tank 130, and can be selectively opened or closed, for example, the second valve port can be opened under the action of negative pressure in the pressurizing chamber 1521, so that the air inlet 131 is connected to the pressurizing chamber 1521 and the water tank 130; otherwise, the second valve port is in a closed state, so that the pressurizing chamber 1521 is not connected to the water tank 130, that is, the first control valve 153 is a one-way air outlet valve, so that the water in the water tank 130 can be placed into the pressurizing chamber 1521.

[0066] In addition, the external force acting on the pressure member 151 may be a pressing force applied to the pressure member 151 by a user through hand pressure or foot pressure.

[0067] In a specific implementation, when the user applies pressing force to the pressure member 151 by stepping on it or using other pressing tools, the pressure member 151 moves toward the pressurizing seat 152, that is, moves from the first position to the second position. During the movement, the pressure member 151 generates negative pressure in the pressurizing chamber 1521 according to the principle of pumping air and pressurizing the pressurizing chamber 1521. The generated negative pressure can open the first control valve 153 to allow the negative pressure to enter the water tank 130 through the air inlet 131, thereby increasing the air pressure in the water tank 130 and squeezing the clean liquid in the water tank 130 out through the water outlet, so that the water tank 130 discharges water in a mechanically controlled manner, without consuming electricity, saving energy and being environmentally friendly. In addition, the control mechanism 150 has a simple structure and low cost, thereby reducing the water discharge cost of the water tank 130.

[0068] In some embodiments, Figure 2 , Figure 6 and Figure 7As shown, the control mechanism 150 also includes at least one elastic return member 154, which is arranged between the water tank 130 and the pressure member 151. The elastic return member 154 is constructed to drive the pressure member 151 from the second position to the first position through its own elastic force.

[0069] It can be understood that when the pressure-applying member 151 moves from the first position to the second position under the action of external force, negative pressure is generated in the pressurizing chamber 1521, and the negative pressure opens the first control valve 153, so that the negative pressure enters the water tank 130 so that the cleaning liquid in the water tank 130 is squeezed out from the water outlet under the action of pressure; thereafter, the elastic reset member 154 drives the pressure-applying member 151 from the second position to the first position through its own elastic force to reset the pressure-applying member 151. At this time, the first control valve 153 is closed, which can prevent the cleaning liquid in the water tank 130 from entering the pressurizing chamber 1521.

[0070] In some embodiments, Figure 2 , Figure 6 and Figure 7 As shown, the control mechanism 150 includes two elastic return members 154 , and the two elastic return members 154 are symmetrically arranged on opposite sides of the pressure member 151 .

[0071] In the embodiment of the present application, the pressure member 151 is driven to reset by two elastic reset members 154 symmetrically arranged on opposite sides of the pressure member 151. In this way, the reset reliability of the pressure member 151 can be improved, and the problem of the pressure member 151 getting stuck due to uneven elastic force applied by the elastic reset members 154 to the pressure member 151 can be avoided.

[0072] The elastic reset member 154 includes but is not limited to a spring.

[0073] In some embodiments, Figures 4 to 7 As shown, the control mechanism 150 also includes a second control valve 155, which is arranged at one end of the pressure channel 1511 away from the pressurizing chamber 1521; when the pressure member 151 moves to the first position, the second control valve 155 opens to connect the pressure channel 1511 with the outside air; when the pressure member 151 moves to the second position, the second control valve 155 closes.

[0074] In this way, the pressure channel 1511 can selectively allow the outside air to communicate through the second control valve 155, so that negative pressure is generated when the pressure member 151 moves to the second position.

[0075] Exemplarily, the second control valve 155 includes but is not limited to a duckbill valve, and its principle is the same as that of the first control valve 153, which will not be repeated here.

[0076] In some embodiments, Figure 2 , Figures 4 to 7 As shown, the control mechanism 150 further includes an elastic member 156 . The elastic member 156 is disposed at one end of the pressure member 151 facing the pressure seat 152 , and the elastic member 156 has a through hole connecting the pressure channel 1511 and the pressure chamber 1521 .

[0077] It is understandable that by providing an elastic member 156 at one end of the pressure member 151 facing the pressurizing seat 152, it is possible to avoid rigid contact between the pressure member 151 and the pressurizing chamber 1521 when the pressure member 151 moves to the second position, thereby extending the service life of the pressure member 151 and the pressurizing chamber 1521.

[0078] In some embodiments, the elastic member 156 is an elastic rubber ring, one end of which is sleeved on one end of the pressure member 151 facing the pressure seat 152. In this way, the connection between the elastic member 156 and the pressure member 151 is simple and low in cost.

[0079] In order to improve the connection reliability between the elastic member 156 and the pressure member 151, a limiting groove may be provided on the outer wall of the pressure member 151, and a limiting protrusion matching the limiting groove may be provided on the inner wall of the elastic member 156. In this way, when the elastic member 156 is sleeved on the end of the pressure member 151, the limiting protrusion is located in the limiting groove to improve the connection reliability between the elastic member 156 and the pressure member 151 and prevent the elastic member 156 from falling off the pressure member 151.

[0080] In some embodiments, Figure 3 As shown, the water tank 130 has a mounting position 133, the pressurizing seat 152 is mounted on the mounting position 133, and the mounting position 133 has a pressurizing chamber connected to the pressurizing chamber 1521, and the air inlet 131 is arranged on the side wall of the pressurizing chamber. In this way, the space of the negative pressure environment is increased, thereby improving the reliability of driving the water tank 130 to discharge water through negative pressure.

[0081] In addition, in order to improve the connection reliability between the elastic reset member 154 and the pressure member 151 and the water tank 130, the pressure member 151 has a first limit portion 1512 at one end away from the pressure seat 152, and the water tank 130 has a second limit portion 132. One end of the elastic reset member 154 is connected to the first limit portion 1512, and the other end of the elastic reset member 154 is connected to the second limit portion 132. In this way, by limiting the circumferential direction of the elastic reset member 154, the position reliability of the elastic reset member 154 is improved, thereby improving the working reliability of the control mechanism 150.

[0082] In some embodiments, the water tank 130 has a receiving groove 134 , and at least one of the second limiting portion 132 and the installation position 133 is disposed in the receiving groove 134 , thereby improving the structural compactness of the floor brush assembly 100 .

[0083] like Figure 3 As shown in FIG. 1 , the water tank 130 has a receiving groove 134 , and the mounting position 133 and the second limiting portion 132 are both located in the receiving groove 134 , thereby improving the compactness of the structure.

[0084] In some embodiments, the water tank 130 includes a water tank upper cover 130b and a water tank lower cover 130a. The water tank upper cover 130b is located above the water tank lower cover 130a and is buckled with the water tank lower cover 130a. The accommodating groove 134, the mounting position 133 and the air inlet 131 are located on the water tank lower cover 130a. The water tank upper cover 130b has an avoidance hole for the control mechanism 150 to pass through. In this way, when the water tank upper cover 130b is buckled with the water tank lower cover 130a, the water tank upper cover 130b can limit the circumference of the control mechanism 150 to prevent the various components in the control mechanism 150 from falling, and can also save the structure for circumferentially limiting the various components in the control mechanism 150, thereby achieving the purpose of simplifying the structure and saving costs.

[0085] In some embodiments, Figure 2 , Figures 4 to 7 As shown, a pressing member 157 is further included, and the pressing member 157 is arranged at one end of the pressure member 151 away from the pressure seat 152, and the pressing member 157 is configured to apply a pressing force to the pressure member 151 under the action of an external force, so that the pressure member 151 moves toward the pressure seat 152. It can be understood that the pressing member 157 forms a pressing button, and the user can apply a pressing force to the pressure member 151 through the pressing member 157, so as to facilitate the user's operation, thereby improving the user's operating comfort.

[0086] It should be noted that the pressing member 157 at least partially protrudes from the surface of the water tank upper cover 130 b , so that the user can apply pressure to the pressure member 151 through the pressing member 157 .

[0087] In addition, in order to improve the positioning accuracy of the pressure member 151 in the second position, in the embodiment of the present application, a first limiting structure (not shown in the figure) is provided on the inner wall of the pressurizing chamber 1521. When the pressure member 151 moves to the second position, the pressure member 151 is configured to abut against the first limiting structure, thereby improving the reliability of the moving position of the pressure member 151, and further improving the reliability of water discharge from the water tank 130.

[0088] Exemplarily, the first limiting structure is, for example, a limiting platform, so as to limit the pressure member 151 at the second position through the limiting platform.

[0089] In some embodiments, Figure 2 , Figure 5 and Figure 7As shown, the pressure piece 151 has a second limiting structure 1513, and the end of the pressure seat 152 facing the pressure piece 151 has a third limiting structure 1522 matching the second limiting structure 1513. When the pressure piece 151 moves to the first position, the first limiting structure and the second limiting structure 1513 are connected. In this way, the pressure piece 151 and the pressure seat 152 can be prevented from being separated or shifted from each other, thereby improving the reliability of the active connection between the pressure piece 151 and the pressure seat 152.

[0090] In some embodiments, the second limiting structure 1513 is a boss disposed on the outer wall of the pressure member 151, and the third limiting structure 1522 is a cam matching the boss. In this way, the structure is simple, easy to process, and low in cost.

[0091] For example, Figure 2 As shown, the second limiting structure 1513 is a boss extending along the circumference of the pressure piece 151, and the third limiting structure 1522 has multiple third limiting structures 1522, which are arranged at intervals along the circumference of the pressure piece 151. In this way, when the pressure piece 151 moves to the first position, the pressure piece 151 is limited by the multiple third limiting structures 1522 and the second limiting structure 1513 to prevent the pressure piece 151 from being separated from the pressure seat 152.
