[0064] Household cleaning equipment such as vacuum cleaners and floor scrubbers have become increasingly popular and have more and more functions. Taking floor scrubbers as an example, existing floor scrubbers have a mopping function in addition to the vacuuming function, and can be dry mopped or wet mopped depending on the application scenario. Exemplarily, a floor scrubber includes a main unit and a floor brush assembly rotatably connected to the main unit, and the main unit can rotate between a lying position and an upright position relative to the floor brush assembly. The main unit has a negative pressure device and a sewage tank, and the floor brush assembly is used to wet mop the surface to be cleaned (such as the ground), and the negative pressure device is used to provide adsorption wind force to suck the sewage generated by the floor brush assembly during the cleaning process into the sewage tank. However, when the main unit lies flat relative to the floor brush assembly, the sewage in the sewage tank easily enters the negative pressure device, thereby affecting the performance of the negative pressure device.

[0065] In order to solve the above problems, the embodiments of the present application provide a floor brush assembly and a cleaning device, wherein a contact switch is arranged on one of the floor brush base and the main host connector in the floor brush assembly, and a trigger mechanism is arranged in one of the main host connector and the floor brush base, wherein the trigger mechanism has a trigger member, and the trigger member moves relative to the contact switch under the drive or push of the main host connector, so that when the main host connector moves to a lying position relative to the floor brush base, the trigger member triggers the contact switch to change the working state of the negative pressure device in the cleaning device through the trigger switch, so that the trigger member can accurately trigger the contact switch, and change the size of the adsorption wind force of the negative pressure device through the contact switch to avoid water from entering the negative pressure device, thereby improving the performance of the negative pressure device, and the structure is simple, reliable and low in cost.

[0066] 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.

[0067] 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 or an automatic cleaning robot for cleaning, for example, the floor. The embodiment of the present application does not specifically limit the type of cleaning device.

[0068] Please refer to Figure 1As shown, the cleaning device includes a floor brush assembly 100 and a main unit 200, the main unit 200 is connected to the floor brush assembly 100, the floor brush assembly 100 includes, for example, a floor brush base 110 and a roller brush connected to the floor brush base 110, and one of the main unit 200 and the floor brush assembly 100 is provided with a clean water tank for storing cleaning liquid, and illustratively, the cleaning liquid can be water or a mixture of detergent and water. A sewage tank 210 and a negative pressure device 220 are also provided in the main unit 200. A sewage pipe connecting the sewage tank 210 and the roller brush is provided between the sewage tank 210 and the roller brush. The negative pressure device 220 is used to provide adsorption wind force. In this way, when the cleaning device cleans the ground, as the cleaning device moves in the forward direction, the roller brush can rotate relative to the ground, and the clean water tank discharges the cleaning liquid. The cleaning liquid can be guided to the roller brush through the pipe, and the roller brush is rotated to clean and mop the ground to achieve the purpose of cleaning the ground. In addition, the adsorption wind force provided by the negative pressure device 220 sucks the sewage generated in the cleaning process into the sewage tank 210 through the sewage pipe.

[0069] Exemplarily, the negative pressure device 220 is disposed at one end of the sewage tank 210 away from the floor brush assembly 100 , and the negative pressure device 220 includes a motor and a negative pressure fan connected to the motor.

[0070] It is understandable that when the main unit 200 is in a lying position relative to the brush assembly 100, the sewage surface in the sewage pipe will be close to the air outlet connecting the negative pressure device 220 and the sewage tank 210. At this time, if the adsorption wind force generated by the negative pressure fan is large, the sewage in the sewage tank 210 will enter the negative pressure device 220 through the air outlet, causing the motor and other electronic components in the negative pressure device 220 to fail to work normally. Therefore, it is necessary to reduce the adsorption wind force of the negative pressure fan or turn off the negative pressure fan to prevent the sewage in the sewage tank 210 from entering the interior of the negative pressure device 220.

[0071] In the embodiment of the present application, the floor brush assembly 100 in the cleaning device is improved to prevent sewage from entering the interior of the negative pressure device 220.

[0072] The structure and working principle of the floor brush assembly 100 in the cleaning device will be described in detail below with reference to the accompanying drawings.

[0073] Please refer to Figures 2 to 11As shown, an embodiment of the present application provides a floor brush assembly 100, which includes a floor brush base 110, a host connector 120 and a contact switch 130. The host connector 120 is hinged to the floor brush base 110, and the host connector 120 is used to connect to the host 200 in the cleaning device. The relative posture between the host connector 120 and the floor brush base 110 can be equivalent to the relative posture between the host 200 and the floor brush base 110. In this way, when the host connector 120 rotates relative to the floor brush base 110 around a fixed rotation axis, the host 200 can be driven to rotate relative to the floor brush base 110 between a lying posture and an upright posture, wherein the contact switch 130 can be set on one of the floor brush base 110 and the host connector 120, and the host A trigger mechanism 140 is provided in one of the connector 120 and the floor brush base 110. The trigger mechanism 140 has a trigger member 141. The trigger member 141 moves relative to the contact switch 130 under the drive or push of the main connector 120. When the main connector 120 moves to a lying position relative to the floor brush base 110, the trigger member 141 triggers the contact switch 130. That is, the contact switch 130 is provided at the position corresponding to the trigger member 141 when the main connector 120 is in the lying position, so as to trigger the contact switch 130 through the trigger member 141 to change the working state of the negative pressure device 220 in the cleaning equipment. For example, the adsorption wind force of the negative pressure device 220 is reduced through the contact switch 130 to prevent the sewage in the sewage tank 210 from entering the interior of the negative pressure device 220.

[0074] In some embodiments, the contact switch 130 is disposed on the host connector 120 , and the trigger mechanism is disposed on one of the host connector 120 and the floor brush base 110 . The host connector 120 drives the contact switch 130 to move synchronously so that the trigger member 141 moves relative to the contact switch 130 .

[0075] In one example, the contact switch 130 and the trigger mechanism are respectively arranged at different parts of the main unit connector 120, wherein the trigger member 141 is movably arranged on the side of the main unit connector 120 facing the floor brush base 110, and the contact switch 130 is fixedly arranged on the main unit connector 120. When the main unit connector 120 is rotated from an upright position to a lying position, for example, until the trigger member 141 abuts against the floor brush base 110, as the main unit connector 120 continues to rotate toward the lying position, the floor brush base 110 pushes the trigger member 141 to move relative to the contact switch 130. When the main unit connector 120 rotates to the lying position, the trigger member 141 triggers the contact switch 130 to change the working state of the negative pressure device in the cleaning equipment to prevent the sewage in the sewage tank 210 from entering the interior of the negative pressure device 220.

[0076] In another example, the contact switch 130 is arranged on the main connector 120, and the trigger mechanism is arranged on the floor brush base 110. The trigger member in the trigger mechanism is, for example, fixedly arranged on the floor brush base 110, and the trigger member 141 is, for example, a columnar structure, a plate structure, etc. For example, the trigger member 141 can be formed into an integrated structure with the floor brush base 110 by injection molding, casting, etc., so that the installation process can be reduced; when the main connector 120 drives the contact switch to move synchronously toward the floor brush base 110, the trigger member 141 and the contact switch 130 move relative to each other, so that when the main connector 120 rotates to a lying position, the trigger member 141 triggers the contact switch 130 to change the working state of the negative pressure device in the cleaning equipment to prevent the sewage in the sewage tank 210 from entering the interior of the negative pressure device 220.

[0077] In other embodiments, the contact switch 130 is disposed on the floor brush base 110 , the trigger mechanism 140 is disposed on one of the host connector 120 and the floor brush base 110 , and the trigger member 141 moves relative to the contact switch 130 under the drive or push of the host connector 120 .

[0078] In one example, the contact switch 130 is disposed on the floor brush base 110, the trigger mechanism 140 is disposed on the main unit connector 120, and the trigger member 141 and the main unit connector 120 move synchronously so as to move relative to the contact switch 130 driven by the main unit connector 120. Exemplarily, the trigger member 141 is a columnar, plate-shaped or cylindrical structure. As long as the main unit connector 120 moves to a lying position relative to the floor brush base 110, the trigger member 141 can trigger the contact switch 130. The structure is simple, the triggering method is simple and reliable, it is easy to implement, and the cost is low.

[0079] When the trigger member 141 is disposed on the host connector 120 , the trigger member 141 can be formed into an integral structure with the host connector 120 by an integral molding method such as casting or injection molding, thereby reducing the installation process and the installation cost.

[0080] In addition, an avoidance space can be provided at a position on the floor brush base 110 corresponding to the trigger member 141 to avoid interference between the trigger member 141 and the floor brush base 110 when the trigger member 141 moves relative to the contact switch 130 driven by the host connector 120, thereby improving the user experience.

[0081] In another example, the trigger mechanism 140 and the contact switch 130 are respectively arranged at different parts of the floor brush base 110. For example, the trigger member 141 is movably arranged on the floor brush base 110, and the contact switch 130 is fixedly arranged on the floor brush base 110. When the main host connector 120 rotates from an upright position to a lying position, the main host connector 120 pushes the trigger member 141 to move relative to the contact switch 130. When the main host connector 120 rotates to a lying position, the trigger member 141 triggers the contact switch 130 to change the working state of the negative pressure device in the cleaning equipment to prevent the sewage in the sewage tank 210 from entering the interior of the negative pressure device 220.

[0082] In addition, it can be understood that when the cleaning device is used normally, the main unit 200 is rotated to an upright position, and the user can push the cleaning device forward by holding the grip rod connected to the main unit 200 to clean the floor; and when it is necessary to clean low areas (such as tables, sofas, coffee tables, bedside tables, beds and other furniture), it is usually necessary to rotate the main unit 200 to a lying position so that the cleaning device can enter the low area for cleaning.

[0083] In some embodiments, the contact switch 130 can adjust the wind speed level of the negative pressure fan in the negative pressure device 220. For example, different adsorption wind forces of the negative pressure fan correspond to different levels. At different wind speed levels, the output adsorption wind forces are different. For example, when cleaning a low area, that is, the main connector 120 is in a lying position, the adsorption wind force output by the negative pressure device 220 at the level will not cause sewage to enter the negative pressure device 220. In this way, the performance of the negative pressure device 220 can be improved while maintaining the cleaning effect.

[0084] In other embodiments, the contact switch 130 may be a micro switch, and a resilient contact 131 is provided on the side of the micro switch facing the trigger member. Since the micro switch has the characteristics of small contact spacing, short action stroke, small pressing force, and rapid switching, in the embodiment of the present application, when the host connector 120 is rotated to a lying position, the micro switch can quickly cut off the power supply of the negative pressure device 220. Since the negative pressure fan will continue to rotate due to inertia for a certain period of time when the power is cut off, and the rotation rate gradually decreases until it stops, in this process, the adsorption wind force also gradually decreases. In this way, when cleaning a low area with a small area, that is, the cleaning time of a low area with a small area is short, the power supply of the negative pressure device 220 is quickly cut off by the micro switch to prevent sewage from entering the negative pressure device 220. At the same time, the adsorption wind force generated by the inertial rotation of the negative pressure fan can meet the cleaning effect for a short time.

[0085] It can be seen that in the embodiment of the present application, a contact switch 130 is arranged on the floor brush base 110, and a trigger mechanism 140 is arranged in one of the main unit connector 120 and the floor brush base 110. The trigger mechanism 140 has a trigger member 141. The trigger member 141 moves relative to the contact switch 130 under the drive or push of the main unit connector 120, so that when the main unit connector 120 moves to a lying position relative to the floor brush base 110, the trigger member 141 triggers the contact switch 130 to change the working state of the negative pressure device 220 in the cleaning equipment by triggering the switch. In this way, the trigger member 141 can accurately trigger the contact switch 130, so that the contact switch 130 can accurately control the working state of the negative pressure device 220 to prevent water from entering the negative pressure device 220, thereby improving the performance of the negative pressure device 220, and the structure is simple and reliable, the cost is low, and the practicability is strong.

[0086] Next, the trigger mechanism 140 and the contact switch 130 are respectively arranged at different positions of the floor brush base 110, and when the main connector 120 rotates to a lying position, the trigger member 141 triggers the contact switch 130, and a detailed introduction is given to changing the working state of the negative pressure device in the cleaning equipment as an example.

[0087] In some embodiments, please refer to Figures 2 to 10 As shown, the contact switch 130 and the trigger mechanism 140 are respectively arranged at different parts of the floor brush base 110, and the trigger member 141 is pushed by the main unit connector 120 to move toward the contact switch 130. For example, the trigger member 141 is movably arranged on the floor brush base 110 and is located directly below the main unit connector 120. In this way, when the main unit connector 120 moves toward a lying position relative to the floor brush base 110, the main unit connector 120 pushes the trigger member 141 to move relative to the contact switch 130. When the main unit connector 120 moves to a lying position, the trigger member 141 just triggers the contact switch 130.

[0088] In the embodiment of the present application, by arranging the trigger mechanism 140 on the floor brush base 110, the installation and wiring of the trigger mechanism 140 can be facilitated, thereby reducing the installation cost.

[0089] In some embodiments, please refer to Figure 2 , Figure 5 and Figure 8 As shown, a pushing portion 121 is provided at a position of the host connector 120 corresponding to the trigger member 141. When the host connector 120 rotates toward the trigger member 141, the pushing portion 121 is used to push the trigger member 141. In this way, the host connector 120 can apply a trigger force to the trigger member 141 through the pushing portion 121, thereby increasing the pushing force per unit area applied to the trigger member 141, thereby improving the reliability of pushing the trigger member 141.

[0090] In some embodiments, the pushing portion 121 can be a pushing protrusion. For example, the surface of the pushing protrusion is, for example, an arc-shaped protrusion. In this way, the unit area of ​​the pushing force applied to the trigger member 141 can be further reduced to improve the concentration of force, thereby improving the reliability of the pushing trigger member 141.

[0091] Alternatively, in other embodiments, the surface of the pushing portion 121 facing the trigger member matches the surface of the trigger member 141 facing the pushing portion 121 , so that when the pushing portion 121 pushes the trigger member 141 , the surface of the pushing portion 121 fits with the surface of the trigger member 141 .

[0092] In some embodiments, please refer to Figures 3 to 10 As shown, the trigger mechanism 140 also includes an elastic member 142, which is connected between the floor brush base 110 and the trigger member 141, and the elastic member 142 is constructed to drive the trigger member 141 to move toward the main connector 120 through its own elastic force. For example, when the main connector 120 rotates from a lying position to an upright position, the elastic member 142 can drive the trigger member 141 to release the trigger relationship with the contact switch 130 through its own elastic force, so that the negative pressure device 220 returns to a normal working state to improve the cleaning effect.

[0093] That is to say, the elastic member 142 can drive the trigger member 141 to move relative to the contact switch 130 through its own elastic force to reset the contact switch 130, thereby restoring the negative pressure device 220 to a normal working state without the need for manual adjustment or resetting, and without the need for other additional resetting structures. The structure is simple, easy to implement, and low in cost.

[0094] The elastic member 142 may be, for example, a spring, such as a tension spring or a compression spring, etc., which is not limited here.

[0095] In some embodiments, the trigger member 141 is, for example, a trigger block, a trigger plate, or a trigger column that can move relative to the contact switch 130 , which is not limited here.

[0096] In some embodiments, the trigger member 141 has a trigger portion 1411, which is disposed on the side of the trigger member 141 facing the contact switch 130. In this way, the accuracy of the trigger member 141 in triggering the contact switch 130 can be improved, and the trigger member 141 can be prevented from accidentally triggering the contact switch 130, thereby improving the user experience.

[0097] Exemplarily, the trigger portion 1411 is, for example, a trigger protrusion, which extends toward one side of the contact switch 130. That is, when the host connector 120 pushes the trigger member 141 toward the lying position and rotates to the lying position, the trigger protrusion on the trigger member 141 is arranged opposite to and abuts against the contact switch 130, thereby further improving the trigger accuracy.

[0098] The trigger protrusion and the trigger member 141 can be formed into an integral structure by integral molding, thereby reducing the installation process and the installation cost.

[0099] In order to further improve the accuracy of the trigger member 141 triggering the contact switch 130, in the embodiment of the present application, please refer to Fig.10 and Fig.11 As shown, an avoidance notch 1412 is provided on the wall surface of the trigger member 141 which is away from the host connector 120 and faces the contact switch 130, and the trigger portion 1411 is located on the side of the avoidance notch 1412 close to the host connector 120. When the host connector 120 pushes the trigger member 141 to move relative to the contact switch 130, the avoidance notch 1412 is used to avoid the contact switch 130. In this way, it can be avoided that the contact switch 130 is accidentally triggered when the host connector 120 is not rotated to a lying position, thereby improving the accuracy of triggering the contact switch 130.

[0100] Among them, the avoidance gap 1412 can be formed by removing part of the material on the outer wall surface of the trigger member 141, for example, removing part of the material of the trigger member 141 facing the contact switch 130, and retaining the material at the position corresponding to the contact switch 130 when the host connector 120 is in a lying position. In this way, a concave-convex structure will be formed on the side of the trigger member 141 facing the contact switch 130, so that the protruding part of the trigger member 141 facing the contact switch 130 is formed as a contact part, and there is no need to form the contact part by adding additional material. The structure is simple, easy to implement, and low cost.

[0101] The avoidance notch 1412 and the contact portion can be formed with the trigger member by integral molding, thereby reducing installation processes and reducing installation costs.

[0102] In some embodiments, the floor brush base 110 has a receiving groove 111 that is open toward one side of the main unit connector 120, the trigger member 141 and the elastic member 142 can be arranged in the receiving groove 111, and the contact switch 130 can be arranged on the groove wall in the receiving groove 111 corresponding to the trigger portion 1411 on the trigger member 141. In this way, by accommodating the trigger member 141, the elastic member 142 and the contact switch 130 in the receiving groove 111, the compactness of the structure can be improved and the overall appearance volume of the floor brush assembly 100 can be reduced.

[0103] A fixing groove may be provided on the groove wall where the contact switch 130 is installed, and the contact switch 130 is embedded and fixed in the fixing groove, so that the contact point of the contact switch 130 faces the trigger member 141 side.

[0104] In addition, a first limiting structure 112 may be provided on the bottom wall of the accommodating groove 111, and one end of the elastic member 142 is connected to the first limiting structure 112; a second limiting structure 1421 may be provided on the end of the trigger member 141 facing the elastic member 142, and the elastic member 142 is connected to the second limiting structure 1421. The first limiting structure 112 and the second limiting structure 1421 are constructed to limit the relative position between the elastic member 142 and the trigger member 141. In this way, the accuracy of the relative position between the elastic member 142 and the trigger member 141 can be improved, thereby improving the accuracy of the moving route of the trigger member 141, and further improving the accuracy of the trigger member 141 triggering the contact switch 130.

[0105] In some embodiments, the first limiting structure 112 and the second limiting structure 1421 can be at least one of a limiting groove and a limiting protrusion. In this way, while meeting the purpose of limiting, the structure is simple, easy to process, and low in cost.

[0106] For example, in Figures 5 to 10 In the embodiment, the first limiting structure 112 is a limiting protrusion, the second limiting structure 1421 is a limiting groove, and the elastic member 142 is a spring. In this way, one end of the elastic member 142 is sleeved on the limiting protrusion, and the other end of the elastic member 142 is arranged in the limiting groove, so as to limit the movement of the elastic member 142 in the horizontal direction through the limiting protrusion and the limiting groove, and only retain the movement of the elastic member 142 in the direction of the elastic force, thereby improving the accuracy of the reset route of the elastic member 142 driving the trigger member 141.

[0107] In some embodiments, please refer to Figures 2 to 10 As shown, the trigger mechanism 140 also includes a limit cover plate 143, which is covered at the notch of the accommodating groove 111 and connected to the floor brush base 110. The limit cover plate 143 is provided with guide holes 1431 that penetrate the two opposite side surfaces of the limit cover plate 143, and at least a part of the trigger member 141 is penetrated through the guide hole 1431. In this way, when the trigger member 141 moves relative to the contact switch 130, it can move along the extension direction of the guide hole 1431, so that the moving path of the trigger member 141 is guided by the guide hole 1431, thereby improving the path accuracy of the trigger member 141, and further improving the accuracy of the trigger member 141 triggering the contact switch 130.

[0108] Among them, the limiting cover plate 143 can be detachably connected to the floor brush base 110. Exemplarily, the limiting cover plate 143 can be detachably connected by a threaded connector, for example, two through holes arranged at intervals for the threaded connector to pass through are provided on the limiting cover plate 143, and two threaded columns are provided in the accommodating groove 111, and threaded holes are provided on the threaded columns. When the limiting cover plate 143 is sealed on the notch of the accommodating groove 111, the threaded connector passes through the through hole and is connected to the corresponding threaded hole, thereby fixing the limiting cover plate 143.

[0109] In addition, the appearance of the limiting cover plate 143 can be consistent with the color of the appearance of the floor brush base 110 to improve the overall aesthetics.

[0110] In order to further improve the movement accuracy and triggering precision of the trigger member 141, in the embodiment of the present application, please refer to Figure 7 and Fig.11 As shown, the trigger member 141 includes a sliding portion 1413 and an abutting portion 1414 connected in sequence, the abutting portion 1414 is located above the sliding portion 1413, the trigger portion 1411 is arranged on the sliding portion 1413, and the cross-sectional area of ​​the abutting portion 1414 is smaller than the cross-sectional area of ​​the sliding portion 1413, so that the sliding portion 1413 is located in the accommodating groove 111 and connected to the elastic member 142, the limiting cover plate 143 can limit the sliding portion 1413, and the abutting portion 1414 is penetrated in the guide hole 1431, and the guide hole 1431 is provided to prevent the sliding portion 1413 from sliding. The hole 1431 can guide the movement of the abutment portion 1414, so that when the main connector 120 rotates, the abutment portion 1414 can be pushed by the pushing portion 121 to drive the trigger member 141 to move, thereby increasing the pushing force per unit area of ​​the main connector 120 against the trigger member 141, and improving the accuracy and reliability of the moving route of the trigger member 141, so that the contact switch 130 can be accurately triggered by the trigger member 141 to avoid the problem of false triggering and improve the performance of the cleaning equipment.

[0111] Exemplarily, the sliding portion 1413 is, for example, a sliding block, and the abutting portion 1414 is, for example, a columnar structure, such as a cylinder, etc., which is not limited here.

[0112] Please continue to refer to Figure 1As shown, the embodiment of the present application also provides a cleaning device 10, which includes a floor brush assembly 100 and a host 200, the host 200 is connected to the floor brush assembly 100, the floor brush assembly 100 includes, for example, a floor brush base 110 and a roller brush connected to the floor brush base 110, one of the host 200 and the floor brush assembly 100 is provided with a clean water tank, the clean water tank is used to store cleaning liquid, the host 200 is also provided with a sewage tank 210 and a negative pressure device 220, and a negative pressure device 220 is provided between the sewage tank 210 and the roller brush. The negative pressure device 220 is used to provide adsorption wind force in the sewage pipe connecting the sewage tank 210 and the roller brush; in this way, when the cleaning device cleans the ground, as the cleaning device moves in the forward direction, the roller brush can rotate relative to the ground, and the clean water tank discharges the cleaning liquid, which can be guided to the roller brush through the pipe, and the roller brush can be rotated to clean and mop the ground to achieve the purpose of cleaning the ground. In addition, the adsorption wind force provided by the negative pressure device 220 can suck the sewage generated in the cleaning process into the sewage tank 210 through the sewage pipe.
