[0057] In the embodiments of the present invention, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0058] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0059] In the embodiments of the present invention, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0060] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it can be understood by those skilled in the art that in the embodiments of the present invention, many technical details are proposed in order to enable the reader to better understand the present invention. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present invention can also be implemented. The division of the following embodiments is for the convenience of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined and referenced with each other under the premise of no contradiction.

[0061] Taking the floor scrubber as an example of cleaning equipment, the floor scrubbers in the prior art have insufficient cleaning capabilities, especially for stubborn stains (such as rice grains stuck on the ground, air-dried ketchup, soy sauce and other stubborn stains, which are difficult to clean). If high-pressure flushing water is used to flush the stubborn stains, although the stubborn stains can be effectively removed, the high-pressure flushing water flow is limited by volume and power. At the same time, in order to ensure the impact force, the water flow area is small and difficult to aim.

[0062] In this regard, the present invention provides a floor brush assembly, see Figure 1 and Figure 2The floor brush assembly 1 includes a floor brush body 11, a high-pressure liquid spray structure 2 and a light emitting device 7. The high-pressure liquid spray structure 2 is arranged on the floor brush body 11. The high-pressure liquid spray structure 2 includes a nozzle 21. The nozzle 21 is tilted downward to form a spraying area on the surface to be cleaned. The light emitting device 7 is arranged on the floor brush body 11. The light emitting device 7 is tilted downward to emit a light beam, and the emitted light beam is projected onto the illuminated area of ​​the surface to be cleaned; wherein the liquid spraying direction of the nozzle 21 is toward the illuminated area.

[0063] In addition, it should be noted that the light emitting device 7 is not limited to being disposed on the floor brush body 11, but may also be disposed on the body 8, handle, etc. of the cleaning device, which are not listed here one by one.

[0064] When in use, a light beam is first emitted through the light emitting device 7 to the illuminated area of ​​the surface to be cleaned. When it is determined that the illuminated area is the area that needs to be cleaned, the high-pressure liquid spray structure 2 is turned on to flush the area that needs to be cleaned. The spray direction of the nozzle 21 is toward the illuminated area. In this way, the high-pressure liquid spray structure 2 can accurately aim at the area that needs to be cleaned on the surface to be cleaned and perform strong cleaning.

[0065] It should be noted that the spray area may completely cover the illumination area; or the spray area may at least partially cover the illumination area; or the spray area and the illumination area may be spaced at a preset distance on the surface to be cleaned. The preset distance may be set according to requirements.

[0066] The present invention uses a high-pressure liquid spray structure 2 to spray high-pressure liquid, so that the area that needs to be cleaned can be strongly cleaned. At the same time, considering that the spraying area of ​​the high-pressure liquid sprayed by the high-pressure liquid spray structure 2 is relatively small and not easy to aim, a light emitting device 7 is provided, and the light emitting device 7 is combined to aim at the area that needs to be cleaned. In this way, the problem of stubborn stains being difficult to clean is solved, and the flushing water flow is easy to aim.

[0067] The direction of the liquid spraying of the nozzle 21 may be the same as or different from the direction of the light beam emitted by the light emitting device 7, as long as the direction of the liquid spraying of the nozzle 21 is toward the illumination area, so that the light beam emitted by the light emitting device 7 is projected on the illumination area of ​​the surface to be cleaned, which is roughly the same as the position where the liquid sprayed by the nozzle 21 forms the injection area on the surface to be cleaned. In this embodiment, the direction of the liquid spraying of the nozzle 21 is the same as the direction of the light beam emitted by the light emitting device 7, so that the liquid spraying direction of the nozzle 21 is aimed more accurately, which is convenient for installation and control. At this time, the nozzle 21 can be fixed together with the light emitting device 7 to limit the relative movement of the nozzle 21 and the light emitting device 7, so as to avoid the situation that the light beam emitted by the light emitting device 7 after rotation is not projected on the illumination area of ​​the surface to be cleaned and the position where the liquid sprayed by the nozzle 21 forms the injection area on the surface to be cleaned is roughly the same. In other embodiments, the liquid spraying direction of the liquid spray and the direction of the light beam emitted by the light emitting device 7 are set at a preset angle, in which case the liquid spraying direction of the liquid spray and the light beam emitted by the light emitting device 7 are respectively tilted downward and roughly converged in the illumination area. The preset angle can be 60° or other angles, which is specifically set according to the spacing and height (relative to the height of the surface to be cleaned) between the light emitting device 7 and the nozzle 21 of the high-pressure liquid spraying structure 2.

[0068] It should be noted that the pressure of the high-pressure liquid spray structure 2 usually refers to a pressure ≥ 2 bar. The specific setting of the pressure value of the high-pressure liquid spray structure 2 can be determined according to the working environment. For example, for factory floors where stains are difficult to clean, the pressure of the high-pressure liquid spray structure 2 is often greater than the pressure on home floors. The pressure of the high-pressure liquid spray structure 2 can also be adjusted according to the type of stains and the difficulty of cleaning the stains. For stains that are difficult to clean, the pressure that needs to be set is often greater than the cleaning pressure required for stains that are easier to clean. More specifically, the high-pressure liquid spray structure 2 also includes a water pump 22 provided on the floor brush body 11, and the water pump 22 is connected to the nozzle 21 and is arranged adjacent to the nozzle 21, so that losses can be reduced.

[0069] The present invention also provides a cleaning device, see Figure 1 and Figure 2 The cleaning device 100 includes a body 8 and the above-mentioned floor brush assembly 1, and the floor brush assembly 1 is connected to the body 8.

[0070] It should be noted that the embodiment of the cleaning device 100 includes the embodiment of the above-mentioned floor brush assembly 1, and the beneficial effects of the above-mentioned floor brush assembly 1 are also applicable to the cleaning device 100.

[0071] The cleaning device 100 may be a floor scrubber, a floor mopping machine, or a sweeping and mopping machine, etc., which are not listed here. The body 8 is also provided with a clean water tank, a dirty water tank 6, a battery pack 4, a negative pressure generating device 5 (such as a main fan), etc., and the floor brush body 11 is also provided with a roller brush 12, etc., which are not listed here.

[0072] For the sake of convenience, the cleaning device 100 is described as a floor scrubber, but this does not mean that the cleaning device 100 is limited to a floor scrubber.

[0073] The floor scrubber includes two roller brushes 12 and a driving motor. The driving motor drives the two roller brushes 12 to rotate. The water in the clean water tank is supplied to the two roller brushes 12 through the clean water waterway. The two roller brushes 12 are driven to rotate by the driving motor. During cleaning, the negative pressure generating device 5 sucks the sewage from the cleaned floor into the sewage tank 6 in the floor scrubber through the sewage waterway, thereby completing the cleaning process.

[0074] For the convenience of control, the cleaning device 100 further includes a switch structure 3, which is connected to the high-pressure liquid spray structure 2 and the light emitting device 7, respectively, and is used to control the opening and closing of the high-pressure liquid spray structure 2 and the light emitting device 7. When it is necessary to clean stains (especially stubborn stains), the light emitting device 7 is turned on, and the light emitting device 7 emits a light beam, which is aimed at the stains, and then the high-pressure liquid spray structure 2 is turned on to wash the stains strongly, so as to achieve the effect of cleaning stubborn stains.

[0075] The switch structure 3 can be arranged in various forms. The switch for controlling the light emitting device 7 and the switch for controlling the high-pressure liquid spraying structure 2 can be arranged separately or together. Figure 3 and Figure 4 In this embodiment, in order to facilitate user operation, the switch for controlling the light emitting device 7 and the switch for controlling the high-pressure liquid spraying structure 2 may be arranged together. Specifically, the switch structure 3 includes a base structure 31 and a key structure 32. The base structure 31 is installed on the body 8. The key structure 32 has an upper surface 321 exposed outside the body 8 and a lower surface 322 opposite to the upper surface 321. The upper surface 321 is provided with a first pressing portion. The lower surface 322 is elastically abutted against the base structure 31 and has a disconnection position separated from the base structure 31 and a connection position abutted against the base structure 31. Wherein, please refer to Figure 3 , when the lower surface 322 is in the disconnected position, the high pressure liquid spraying structure 2 is closed; please refer to Figure 4, when the lower surface 322 is in the connection position, the high-pressure liquid spraying structure 2 is turned on. The switch structure 3 also includes a second pressing portion, and the second pressing portion is electrically connected to the light emitting device 7. In this embodiment, the first pressing portion and the second pressing portion can be arranged together, or they can be arranged in the same structure; or the first pressing portion and the second pressing portion can be arranged separately, and each can be independently pressed and controlled. Among them, the second pressing portion can be a touch button or a press button, and no specific limitation is made here.

[0076] When it is necessary to clean stains (especially stubborn stains), the user presses the second pressing part with his finger, the light emitting device 7 is turned on and emits a light beam, and after aiming, the user can continue to press the first pressing part, so that the high-pressure liquid spraying structure 2 is turned on when the lower surface 322 of the key structure 32 contacts the base structure 31 and reaches the connection position, which is convenient for the user to operate. The lower surface 322 and the base structure 31 are elastically abutted, and the lower surface 322 and the base structure 31 are provided with elastic parts, or the switch structure 3 also includes a spring 33, and the spring 33 is arranged between the base structure 31 and the key structure 32. When the user presses the first pressing part until it contacts the base structure 31, the spring 33 is in a compressed state; when the user releases the first pressing part, the first pressing part is elastically reset under the action of the elastic reset force of the spring 33, and the first pressing part is separated from the base structure 31, and the high-pressure liquid spraying structure 2 is closed.

[0077] Of course, the control of the light emitting device 7 and the high-pressure liquid spraying structure 2 can also be automated. For example, when a stubborn stain is detected, the light emitting device 7 is triggered to emit a light beam, and when it is detected that the illuminated area of ​​the light beam emitted by the light emitting device 7 coincides with the area of ​​the stain, the high-pressure liquid spraying structure 2 is controlled to be turned on. Among them, the detection of the stubborn stain and whether the illuminated area of ​​the light beam emitted by the light emitting device 7 coincides with the area of ​​the stain can be performed by conventional image processing technology, which will not be described in detail here.

[0078] The present invention provides a cleaning system, which includes the cleaning device 100. The embodiment of the cleaning system includes the embodiment of the cleaning device 100, and the beneficial effects of the cleaning device 100 are also applicable to the cleaning system.

[0079] The cleaning system may also include a cleaning base station or a base for charging, etc., which is not specifically limited here.

[0080] The present invention provides a control method for the above-mentioned cleaning device. The cleaning device 100 includes the structure of the above-mentioned embodiment, and the beneficial effects of the above-mentioned embodiment can also be applied to this embodiment.

[0081] The following is an explanation of the implementation details of the control method of the cleaning device 100 according to the first embodiment of the present invention. The following content is only the implementation details provided for the convenience of understanding and is not necessary for the implementation of this solution.

[0082] The specific process of this implementation is as follows: Figure 5 As shown, specifically including:

[0083] Step S210, in response to the cleaning instruction, controlling the light emitting device 7 to aim at the stain to be cleaned;

[0084] It should be understood that the executor of the control method of the cleaning device 100 provided by the present invention is the cleaning device, which may be, but is not limited to, a floor scrubber, a washer-mop machine, etc. The cleaning instruction may be a cleaning instruction input by the user (for example, the user presses a corresponding button or touch screen for cleaning stubborn stains, etc.), or it may be a cleaning instruction sent by the cleaning device 100 when stubborn stains are detected during the cleaning process. The light emitting device 7 is controlled to be aimed at the stain to be cleaned, and image recognition technology may be used to determine whether the light beam emitted by the light emitting device 7 reaches the area corresponding to the stain to be cleaned in the illuminated area of ​​the surface to be cleaned. If it does not reach the area, the cleaning device 100 is controlled to rotate or the light emitting device 7 is controlled to rotate until the light beam emitted by the light emitting device 7 reaches the area corresponding to the stain to be cleaned in the illuminated area of ​​the surface to be cleaned.

[0085] Step S220, when the light emitting device 7 is aimed at the stain to be cleaned, the high-pressure liquid spraying structure 2 is controlled to spray liquid.

[0086] It should be understood that since the positions of the emitted light beam hitting the illuminated area of ​​the surface to be cleaned and the spraying area of ​​the liquid spray structure are roughly the same, when the light emitting device 7 is aimed at the stain to be cleaned, the spraying direction of the high-pressure liquid spray structure 2 is also aimed at the area to be cleaned, so that strong cleaning can be performed.

[0087] The present invention first controls the light emitting device 7 to emit a light beam to the illuminated area of ​​the surface to be cleaned to reach the stain to be cleaned. When the light beam reaches the illuminated area of ​​the surface to be cleaned and reaches the stain to be cleaned, the direction of the high-pressure liquid spray structure 2 spraying liquid is also aimed at the area to be cleaned. At this time, the high-pressure liquid spray structure 2 is turned on to flush the area to be cleaned. In this way, the high-pressure liquid spray structure 2 can accurately aim at the area to be cleaned on the surface to be cleaned, and powerfully clean the stains, which can effectively remove stubborn stains.

[0088] In addition, the floor brush body 11 includes a shell and a roller brush 12, and the roller brush 12 is rotatably mounted on the shell; the cleaning device 100 includes a negative pressure generating device 5 provided on the body 8 and / or the floor brush body 11, and the negative pressure generating device 5 is used to absorb dirt on the roller brush 12;

[0089] Accordingly, after step S220, the control method includes:

[0090] Step S230 , controlling to increase the power of the negative pressure generating device 5 and the rotation speed of the roller brush 12 .

[0091] It should be understood that during flushing, the stain cleaning capacity can be increased by increasing the power of the negative pressure generating device 5 and the rotation speed of the roller brush 12. The increase in the power of the negative pressure generating device 5 can be compared with the power value of the negative pressure generating device 5 during normal use plus a preset power value, for example, the power value of the negative pressure generating device 5 during normal use is 90W, and the power of the negative pressure generating device 5 is increased to 120W when the power is increased; similarly, the increase in the rotation speed of the roller brush 12 can be compared with the rotation speed value of the roller brush 12 during normal use plus a preset speed value, for example, the rotation speed value of the roller brush 12 during normal use is 450r / min, and the rotation speed of the roller brush 12 is increased to 600r / min when the rotation speed is increased.

[0092] like Figure 6 As shown, the control method of the cleaning device 100 involved in the second embodiment, before the step S220 and after the step S210, the control method includes:

[0093] Step S231, obtaining the dirtiness of the current stain to be cleaned;

[0094] It should be understood that the degree of dirtiness of the current stain to be cleaned can be obtained based on image recognition technology, or it can be detected and obtained through a dirt sensor, wherein the dirt sensor can be a pipe set in the cleaning device 100 for recovering sewage. For example, taking the cleaning device 100 as a floor scrubber, the dirt sensor is set in a pipe between the suction port of the floor scrubber and the sewage tank 6.

[0095] Accordingly, the step S220 includes:

[0096] Step S221, when the light emitting device 7 is aimed at the stain to be cleaned, the working parameters of the high-pressure liquid spraying structure 2 are determined according to the dirtiness of the stain to be cleaned, and the working parameters include the water flow size and / or the spraying time;

[0097] It should be understood that the larger the current stain to be cleaned, the larger the water flow size sprayed by the high-pressure liquid spray structure 2, or the longer the spraying time, the better. The setting of the working parameters can also match the corresponding water flow size and spraying time according to different types of dirt. For example, conventional stubborn stains may only require increasing the spraying time, while for some special stains (such as those that are more likely to remain or have high viscosity), it is necessary to increase the water flow size and even extend the spraying time.

[0098] Step S222, controlling the high-pressure liquid spraying structure 2 to spray liquid according to the determined water flow size and / or spraying duration.

[0100] The memory 302 and the processor 301 are connected in a bus manner, and the bus may include any number of interconnected buses and bridges, and the bus connects various circuits of one or more processors 301 and the memory 302 together. The bus can also connect various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and are therefore not further described herein. The bus interface provides an interface between the bus and the transceiver. The transceiver can be one element or multiple elements, such as multiple receivers and transmitters, providing a unit for communicating with various other devices on a transmission medium. The data processed by the processor 301 is transmitted on a wireless medium through an antenna, and further, the antenna also receives data and transmits the data to the processor 301.

[0101] The processor 301 is responsible for managing the bus and general processing, and can also provide various functions, including timing, peripheral interfaces, voltage regulation, power management and other control functions. The memory 302 can be used to store data used by the processor 301 when performing operations.

The aforementioned storage medium includes: U disk, mobile hard disk, read-only memory (ROM, Read-Only Memory), random access memory (RAM, Random Access Memory), disk or optical disk and other media that can store program codes.
