When the existing cleaning equipment is used for self-cleaning, a water pump is used for controlling the water outlet of a water tank, so that cleaning pieces on the cleaning equipment are cleaned by water. During the cleaning process, the motor located inside the cleaning device will suck the cleaned sewage away. The cleaning piece is cleaned by repeating the steps of adding water, cleaning and absorbing water. However, the cleaning piece cannot be thoroughly cleaned by water washing, so that bad effects such as adhesion and bacteria breeding on the cleaning piece, peculiar smell generation and the like can be caused, and the use of a user is greatly influenced.

To this end, the present disclosure provides a cleaning system to overcome the shortcomings of the existing cleaning devices that are not thoroughly cleaned.

The cleaning system of the present disclosure includes a handheld cleaning device and a base station. The hand-held cleaning device may be a hand-held cleaning device, a hand-held vacuum cleaner, a hand-held floor cleaning device, etc., as is well known to those skilled in the art.

In detail, the hand-held cleaning device includes a body assembly and a floor brush assembly rotatably coupled to the body assembly. The floor brush assembly is used for cleaning a working surface and comprises a floor brush shell and a rolling brush arranged at the front side edge of the floor brush shell. In the process of cleaning work of the handheld cleaning equipment, the rolling brush is attached to the working surface to be cleaned, and spin movement is carried out all the time in the working process, so that the cleaning capability is improved.

The base station is configured for placing the handheld cleaning appliance, for example, when the handheld cleaning appliance 1 is in operation, the user can place it on the base station. The base station not only provides support for the handheld cleaning device, but also can charge the handheld cleaning device and facilitate self-cleaning of the handheld cleaning device. Specifically, a cleaning tank is arranged on a base of the base station, and a UV light component is arranged in the cleaning tank.

In the case of a hand-held cleaning device placed at a base station, the cleaning tank is configured to house at least a portion of the roll brush. And a roller brush in a wet state, a certain gap is formed between the surface of the roller brush facing the UV light component and the UV light component, so that light emitted by the UV light component can be irradiated onto at least part of the surface of the roller brush through the gap.

The light that the UV optical subassembly sent is the UV light, through shining the UV light on the round brush surface to realize sterilizing the cleaning to the round brush. Therefore, the quantity of bacteria attached to the rolling brush can be effectively reduced, and peculiar smell generated by bacterial breeding is avoided, so that the use experience of a user can be improved.

For a better understanding, the specific structure and effects of the cleaning system of the present disclosure are described in detail below in connection with specific embodiments with reference to fig. 1 to 11 of the drawings of the specification.

Referring to fig. 1, in this embodiment, the cleaning system comprises a handheld cleaning device 1 and a base station 2. Wherein the handheld cleaning appliance 1 comprises a body assembly 15, a brush assembly 11 rotatably connected to the body assembly 15. The body assembly 15 includes a body 16 and functional parts such as a clean water tank, a sewage tank, etc., provided on the body 16, and the floor brush assembly 11 is configured to contact a work surface such as the floor to clean the floor. The body assembly 15 is rotatably connected to the floor brush assembly 11 so that a user can adjust a rotation angle between the body assembly 15 and the floor brush assembly 11, etc., as needed, and the disclosure will not be described in detail herein.

The cleaning tank is configured to supply liquid to the area where the roller brush 13 is located under the control of the water pump when the cleaning system performs self-cleaning operation, so that the roller brush 13 can be cleaned in the cleaning tank 22. Meanwhile, the main motor inside the body assembly 15 sucks sewage into the sewage tank when the roller brush 13 is cleaned. Repeating the steps, and stopping the water pump from running the water tank to finish water supply after the water is cleaned for a plurality of times.

Referring to fig. 1 and 3, the floor brush assembly 11 includes a floor brush housing 12, a roller brush 13 provided at a front side edge of the floor brush housing 12, and rollers 14 provided at left and right sides of the floor brush housing 12.

In detail, the rolling brush 13 is capable of spinning under the control of a motor. During a cleaning operation by a user using the handheld cleaning device 1, a part of the surface of the roller brush 13 is configured to be in contact with the work surface to be cleaned, and the roller brush 13 always performs a spinning motion during this process. The working surface to be cleaned is rubbed by rolling and constantly rotating.

The rollers 14 are provided with two rollers, which are respectively positioned at the left and right sides behind the floor brush housing 12, and the rollers 14 are controlled by a driving device, such as a motor, and are configured to be attached to the surface to be cleaned, so that when the driving device drives the rollers 14 to rotate, the handheld cleaning device 1 can be assisted to move on the surface to be cleaned.

Referring to fig. 3, the base station 2 in the cleaning system is configured for placement of a handheld cleaning device 1. In order to enable a stable placement of the handheld cleaning appliance 1, tilting or shaking thereof is avoided. The end surface of the base 21 of the base station 2 may be configured to a shape that is compatible with the bottom of the floor brush assembly 11.

Referring to fig. 4, a base 21 of the base station 2 is provided with a cleaning tank 22, a receiving portion 24, a limiting portion 211, and a charging assembly 25. Wherein a UV light assembly 23 is provided in the cleaning tank 22. Wherein the receptacle 24 is configured to receive a cleaning accessory, such as a backup roll brush 13, a fuselage extension, or the like, for use with the cleaning system. The user can place the conventional cleaning accessory in the accommodating part 24 according to the actual use requirement, so that the cleaning efficiency of the user is improved.

Referring to fig. 3, the stopper 211 is configured to accommodate at least a portion of the roller 14. Referring to fig. 4, the limiting part 211 is formed by the cooperation of a groove and/or a protrusion structure provided on the base 21 of the base station 2. The limiting portion 211 can limit the movement of the roller 14 in the horizontal direction, and the protruding structure in the limiting portion 211 supports the hand-held cleaning device 1 to a certain extent. In this way, the degree of stability between the handheld cleaning appliance 1 and the base 21, as well as the degree of safety, is improved.

Referring to fig. 5, in the case where the hand-held cleaning device 1 is placed on the base 21 of the base station 2, at least part of the roller brush 13 is accommodated in the cleaning bath 22, and the roller brush 13 in a wet state has a certain gap between the surface thereof facing the UV light assembly 23 and the UV light assembly 23. In this way, the UV light assembly 23 located in the cleaning tank 22 can make the light emitted by it, i.e. the UV light, irradiate at least part of the surface of the roller brush 13 through the gap, so as to perform sterilization and cleaning on the roller brush 13.

In one embodiment of the present disclosure, the cleaning tank 22 is configured to have a shape adapted to a part of the surface of the roll brush 13, for example, the cleaning tank 22 has a circular arc-shaped groove structure.

In one embodiment of the present disclosure, the roller brush 13 is different in bristle state in a dry state and in a wet state. Specifically, after the cleaning operation is performed or the brush 13 is wetted by the water, the brush bristles will be slightly contracted, which may be understood as the brush bristles will be attached to the brush body. In particular, in one embodiment of the present disclosure, the diameter of the roller brush 13 in the dry state may be, for example, 60mm (millimeters), and then its diameter in the wet state is > 50mm (millimeters).

By reasonably setting the supporting relationship between the hand-held cleaning device and the base station, it is possible to select the surface of the roller brush 13 to be in line contact with the bottom wall of the cleaning tank 22 when the roller brush is in a dry state. This arrangement makes it possible for the handheld cleaning appliance 1 to create a sufficiently large negative pressure at the location of the washing tub 22 during self-cleaning of the roller brush 13, in order to suck away the sewage flowing into the washing tub 22 during self-cleaning of the roller brush 13. In addition, the rolling brush can be ensured to have smaller resistance with the inner wall of the cleaning tank 22 during rotation.

When the roller brush 13 is wetted with water, the diameter of the roller brush 13 becomes small, which makes a minute gap between the surface of the roller brush 13 and the groove bottom 221 of the cleaning groove 22, for example, a gap of 2.5 to 3mm can be formed. The UV light emitted by the UV light assembly 23 can thus be directed through the gap onto the surface of the roller brush 13 as widely as possible. This is because the UV light emitted from the light source of the UV light assembly 23 is irradiated outwards at an angle, the farther the surface of the roller brush 13 is from the UV light assembly 23, the larger the surface of the roller brush 13 is irradiated, and when the UV light emitted from the light source of the UV light assembly 23 irradiates the surface of the roller brush 13 through the gap, the irradiation range of the UV light gradually increases, thereby ensuring that as many surfaces of the roller brush 13 as possible are irradiated with the UV light. In one embodiment of the present disclosure, by reasonably arranging the positional relationship between the UV light assembly 23 and the roller brush 13, it is ensured that the surface of the roller brush 13 in the extending direction (i.e., the axial direction) can be irradiated with UV light. Thereby, when the rolling brush 13 is rotating, it is ensured that all surfaces of the rolling brush 13 in the circumferential direction and the axial direction are irradiated with UV light.

In other embodiments of the present disclosure, the surface of the roller brush 13 may have a gap with the bottom wall of the cleaning tank 22 in the dry state, that is, a gap between the surface of the roller brush and any position of the cleaning tank 22, which will not be described in detail herein.

In actual use, the self-cleaning function may be activated after the user has placed the handheld cleaning device 1 in the base station 2 in the seat 21. During self-cleaning, the roller brush 13 performs a spinning motion under the control of a motor, and the UV light assembly 23 emits UV light for sterilization after running. The light can be irradiated onto a part of the surface of the roll brush 13 through the cleaning tank 22. As the roller brush 13 is continuously spinning, the light emitted from the UV light assembly 23 can be irradiated to the entire surface of the roller brush 13. So as to realize the sterilization and cleaning of the rolling brush 13, reduce bacterial communities attached to the surface of the rolling brush 13, avoid bacteria from breeding and diffusing peculiar smell, and further prolong the service life of the rolling brush 13.

Referring to fig. 4, the extending direction of the cleaning tank 22 is denoted as the X-axis direction, and the cleaning tank 22 is divided into a front tank wall 222 and a rear tank wall 223, with a tank bottom 221 extending along the X-axis direction of the cleaning tank 22 being defined.

Specifically, referring to fig. 8, the uv light assembly 23 is disposed on the rear groove wall 223 of the cleaning groove 22 in the X-axis direction. Since the surface of the roller brush 13 in a dry state is in line contact with only the groove bottom 221 of the cleaning groove 22, there is a gap between the roller brush 13 and the rest of the cleaning groove 22 and between the UV light assemblies.

In order to enable the light emitted by the UV light assembly 23 to impinge on the surface of the roller brush 13. It is necessary to provide a through hole at a position of the cleaning tank 22 corresponding to the UV light assembly 23. The through hole is configured to pass and irradiate light emitted from the UV light assembly 23 onto a part of the surface of the roll brush 13.

Referring to fig. 5 and 6, the UV light assembly 23 includes a lamp housing 234, a cover plate 233, a lamp panel 232, and a UV lamp 231 disposed on the lamp panel 232. In actual use, the lamp housing 234, cover 233 and lower portion of the cleaning tank 22 cooperate to form a sealed chamber. The lamp panel 232 is arranged inside the chamber, so that the working environment of the lamp panel 232 is always in a sealed state, and the service life of the UV light assembly 23 is prolonged. Specifically, the cover plate 233 is fixedly connected to the outer wall below the cleaning tank 22. The lamp panel 232 is located above the cover plate 233, and the lamp panel 232 can be fixedly connected with the cleaning tank 22 by the cover plate 233. A lamp cover 234 is provided above the lamp plate 232, and the lamp cover 234 is configured to allow light emitted from the UV lamp 231 to pass therethrough.

The lamp shade 234 is disposed at a position of the through hole formed in the cleaning tank 22, and is sealed and fixed with the through hole. Referring to fig. 6, the uv light assembly 23 is a long strip-shaped structure extending in the X-axis direction. The lamp housing 234 is hermetically fixed to the through hole of the cleaning tank 22 by ultrasonic welding. Through the sealing, the lamp shade 234 can block the through hole formed in the cleaning tank 22, so that the moisture in the cleaning tank 22 does not contact with the UV lamp 231 and the lamp panel 232 along the through hole. In this way, the UV light assembly 23 is protected, extending its lifetime.

Further, the UV light assembly 23 is fixedly disposed with the cleaning tank 22. The angle of the light emitted by the UV lamp 231 and the irradiation range can be kept in a stable range, so that the sterilization efficiency and the sterilization effect of the cleaning system during self-cleaning can be in a relatively stable state, and the cleaning effect can not be changed due to vibration or collision.

In another embodiment of the present disclosure, the lamp housing 234 and the cleaning tank 22 may also be fixedly sealed together by a sealant.

In another embodiment of the present disclosure, in the region where the lamp housing 234 corresponds to the through hole, the outer end surface of the lamp housing 234 is flush with the inner wall of the cleaning tank 22, i.e., the lamp housing 234 can completely fill the through hole opened on the cleaning tank 22, so that the inner wall of the cleaning tank 22 is kept relatively smooth. Thus, after the lamp shade 234 and the cleaning tank 22 are sealed and fixed, when the cleaning system performs the self-cleaning function, moisture cannot be accumulated in the cleaning tank 22, and the sterilization cleaning effect of the UV light assembly 23 cannot be affected by accumulated water on the outer wall of the lamp shade 234 to penetrate and irradiate.

In another embodiment of the present disclosure, referring to fig. 6, the number and positions of the lamp covers 234 are consistent with the number and positions of the UV lamps 231 provided on the lamp panel 232 in the UV light assembly 23. And, the corresponding cleaning tank 22 is provided with a through hole for matching with the lampshade 234. In this way, the light emitted from the UV lamp 231 can pass through the lamp housing 234 and the through-hole and be irradiated on at least part of the surface of the roller brush 13. In the UV light assembly 23 of the present disclosure, a plurality of UV lamps 231 may share a lamp panel 232, the lamp panel 232 is encapsulated under the cleaning tank 22 by a cover plate 233, each UV lamp 231 is correspondingly provided with a lamp cover 234, the cleaning tank 22 is provided with a through hole at each lamp cover 234, and at least two lamp covers 234 are respectively buckled on the corresponding UV lamps 231 and are matched with the corresponding through holes provided by the cleaning tank 22. In other embodiments of the present disclosure, the lamp cover 234 of the present disclosure may also have a strip shape, and the extending direction of the lamp cover is consistent with that of the lamp panel 232, so that all the UV lamps 231 are fastened together by one lamp cover 234. Accordingly, the cleaning tank 22 is provided with an elongated through hole which is matched with the cleaning tank 22, and will not be described in detail herein. Just because the UV light irradiates the more surface of the roller brush 13 through the gap, the lamp covers 234 can be distributed in the cleaning tank 22 at intervals, so that the number of the lamp covers 234 and the UV lamps 231 can be saved, and more irradiation area of the roller brush can be ensured. In one embodiment of the present disclosure, the light emitted from the UV lamp 231 is configured to irradiate the entire surface of the roller brush 13 corresponding to the UV lamp 231 and extending in the X-axis direction. That is, the UV light does not irradiate the entire circumferential surface of the roll brush 13, which is required to be achieved by controlling the roll brush 13 to rotate, but may be irradiated onto the entire surface of the roll brush 13 corresponding to the UV lamp 231 and extending in the X-axis direction.

It is noted that when using UV light for sterilization and cleaning, the UV light emits ultraviolet light with a large energy, which is advantageous for killing bacteria. But this light, if it is directed onto the user's skin or into the user's eyes, can cause discomfort to the user. Therefore, it is necessary to change the position or the light emitting angle of the UV light assembly 23 so that the light emitted from the UV light assembly 23 can be irradiated only to the inside of the cleaning system and not to the outside.

Referring to fig. 8, in a preferred embodiment of the present disclosure, the UV light assembly 23 is disposed on the rear tank wall 223 of the cleaning tank 22. At this time, the light emitted from the UV light assembly 23 is configured to be blocked by the floor brush housing 12 and the roll brush 13 so that the light does not irradiate other areas. In this way, the user can be prevented from being aware of or being irradiated by the light emitted by the UV light assembly 23, and the use safety of the product is improved.

With continued reference to fig. 6, the length of the uv light assembly 23 in the X-axis direction is close to the length of the roller brush 13. Specifically, the length of the lamp panel 232 depends on the angle of light emitted from the UV lamp 231 to be an optimal angle capable of covering the surface of the roller brush 13 in the X-axis direction. According to the luminous angle of the UV lamps 231, a plurality of UV lamps 231 are reasonably arranged on the lamp panel 232 along the X-axis direction at intervals, so that the light rays emitted by the UV lamps 231 can fully cover the surface of the rolling brush 13 in the X-axis direction, and when the rolling brush 13 performs spin movement, the light rays can irradiate the whole surface of the rolling brush 13, and sterilization and cleaning of the rolling brush 13 are realized.

Referring to fig. 11, the light emitted from the uv lamp 231 has a certain angle, and the light emitted therefrom is always irradiated outward along a predetermined angle. That is, the area within the included angle of the light rays can be irradiated by the light rays emitted from the UV light assembly. Further, in order to allow the light emitted from the UV light assembly 23 to cover more of the surface of the roller brush 13, the light emitting angle of the UV lamp 231 may be adjusted.

With continued reference to fig. 11, there is an intersection between the emitted light rays between two adjacent UV lamps 231. Also, in order to enable the UV lamp 231 to irradiate more of the surface of the roller brush 13, the blanket irradiation sterilization cleaning is realized. The intersection of the emitted light rays of the adjacent two UV lamps 231 is located outside the corresponding surface of the roller brush 13. Referring to the view direction of fig. 11, the UV lamps 231 are positioned below the roller brush 13, and the intersection points of the light rays emitted from two adjacent UV lamps 231 are positioned outside the lower surface of the roller brush 13, i.e., below the lower surface of the roller brush 13, so that it is ensured that the lower surface of the roller brush 13 is irradiated with UV light rays.

Of course, the intersection point of the light emission angles of the adjacent two UV lamps 231 may be disposed just to be closely attached to the surface of the roll brush 13.

In one embodiment of the present disclosure, the light emitting angle of the UV lamp 231 is 130 °. Through a plurality of tests, when the light emitting angle of the UV light is set at 130 °, the coverage of the light emitted from the UV lamp 231 is maximum, and the sterilization and cleaning effects are optimal. Further, after the UV lamps 231 are disposed on the lamp panel 232 at intervals, sterilization cleaning can be achieved with a smaller number of UV lamps 231 while securing a sterilization cleaning range and effect. The manufacturing costs of the UV light assembly 23 can also be reduced relative to other angles.

Fig. 8 illustrates an embodiment in which UV light assembly 23 is disposed at rear sump wall 223 of cleaning tank 22. In this embodiment, the light emission angle of the UV lamp 231 is configured to: the light emitted from the UV lamp 231, which irradiates outside the surface of the roll brush 13, is configured to be blocked by the floor brush housing 12 or blocked by the cleaning tank 22. In the embodiment shown in fig. 8, in order to ensure that the UV lamp 231 can be irradiated on as many surfaces of the roller brush 13 as possible, a UV lamp 231 having a large light emission angle, for example 130 °, may be selected. Most of the light irradiates on the surface of the roller brush 13 facing the rear groove wall 223, and the light toward the rear side (right direction in fig. 8) of the roller brush 13 is blocked by the rear groove wall 223 or by the floor brush housing 12, and the light on the side is not emitted outward and is observed by the user. Light rays toward the front side (left direction in fig. 8) of the roller brush 13 are blocked by the roller brush 13, specifically, the surface of the roller brush has a point, a straight line of the point where the point is located with the UV lamp 231 is a tangent line of the point, and the light rays toward the front side of the roller brush 13 do not exceed the tangent line; or light toward the front side (left direction in fig. 8) of the roller brush 13 is blocked by the front groove wall 222 so that the light of the side is not emitted outward from the gap between the roller brush 13 and the cleaning groove 22, thereby being prevented from being observed by the user.

In this embodiment, since the gap between the front side of the roller brush 13 and the cleaning tank 22 communicates with the outside after the roller brush 13 is fitted with the cleaning tank 22, it is necessary to reasonably set the position of the UV lamp 231 on the rear tank wall 223 and a reasonable light emitting angle to prevent light from being radiated outward from the gap. In one embodiment of the present disclosure, the UV lamp 231 may be irradiated obliquely upward on the roller brush 13, so that it may be irradiated on the groove bottom 221 or the front groove wall 222 of the cleaning groove 22 even if a part of the light exceeds the edge of the roller brush 13.

Referring to fig. 9, a UV light assembly 23 is disposed on a front tank wall 222 of the cleaning tank 22 in an X-axis direction in another embodiment of the present disclosure. Otherwise, as in the previous embodiment, the difference between this embodiment and the above embodiment is that the UV light assembly 23 is disposed at a different position, and the emission angle range of the UV lamp 231 needs to be adjusted accordingly. It should be noted that, in practical use, the specific position and the light emitting angle of the UV light assembly 23 need to be adjusted according to the structures of the floor brush assembly 11 and the cleaning tank 22, so that the light emitted by the UV lamp 231 can be blocked by the roller brush 13, the floor brush housing 12, and the base station 2.

In another embodiment of the present disclosure, the UV light assembly 23 may also be disposed at the groove bottom 211 of the cleaning groove 22 in the X-axis direction, referring to fig. 7. In this embodiment, the roller brush 13 is in line contact with the surface of the lamp housing 234 in the dry state. When the UV lamp 231 irradiates vertically upward, a part of UV light is still irradiated onto the surface of the roller brush 13 from the gap between the roller brush 13 and the cleaning tank 22. When the roller brush 13 is in a wet state, a gap is formed between the roller brush 13 and the entire lamp housing 234, thereby ensuring that UV light can be irradiated onto as much surface of the roller brush 13 as possible. In addition, when the UV lamp 231 is irradiated vertically upward, the right light in the view is blocked by the rear groove wall 223 or the ground brush housing 12, and the left light in the view is blocked by the front groove wall 222. Of course, it is also possible to choose not to radiate light beyond the outer contour of the roller brush 13.

Specifically, the front surface of the roller brush away from the floor brush has a first point, a straight line of the first point and the point where the UV lamp 231 is located is a tangent line of the first point, and a ray of light (left direction in fig. 7) toward the front side of the roller brush 13 does not exceed the tangent line of the first point; the rear surface of the roller brush near the floor brush has a second point, and a straight line of the second point with the point where the UV lamp 231 is located is a tangent to the second point, and a ray (right direction in fig. 7) toward the rear side of the roller brush 13 does not exceed the tangent of the second point. Of course, the number of UV light assemblies 23 is not limited to just one set, depending on the actual use requirements. Two or more sets of UV light assemblies 23 may also be provided. The arrangement direction of the UV light assembly 23 is not limited to the X-axis direction, as long as the sterilization and cleaning functions can be performed when the cleaning system performs self-cleaning.

In one embodiment of the present disclosure, the UV lamps 231 are provided in at least two rows, wherein at least one row of UV lamps 231 is arranged at intervals in the X-axis direction at the rear tank wall 223 of the cleaning tank 22; at least one row of UV lamps 231 is arranged at intervals in the X-axis direction at the front tank wall 222 of the cleaning tank 22. I.e. at least one row of UV light assemblies 23 is provided at each of the front trough wall 222 and the rear trough wall 223 of the washing trough 22, whereby more surface of the roll brush 13 can be irradiated. Thus, the sterilization and cleaning efficiency can be improved, and the sterilization and cleaning time can be shortened.

In this embodiment, the position of the UV lamp 231 in the cleaning tank 22 on the front tank wall 222 may be higher than the position of the UV lamp 231 in the cleaning tank 22 on the rear tank wall 223. For example, the UV lamp 231 on the rear tank wall 223 may be disposed at a position of the rear tank wall 223 near the tank bottom 221, and the UV lamp 231 on the front tank wall 222 may be disposed at a position of the front tank wall 222 near the opening of the cleaning tank 22. This is because the light of the UV lamp 231 on the rear groove wall 223 can be blocked by the front groove wall 222 and does not radiate to the outside from the gap between the roller brush 13 and the front side wall 222. Whereas, if the UV lamp 231 located on the front groove wall 222 is disposed too close to the groove bottom 221, light emitted therefrom may be radiated from the gap between the roller brush 13 and the front side wall 222 to the outside, thereby being sensed by the user.

In another embodiment of the present disclosure, the UV lamps 231 located on the front groove wall 222 are disposed opposite to or offset from the UV lamps 231 located on the rear groove wall 223 by a predetermined distance.

Or a part of the front groove wall and a part of the rear groove wall are connected into a straight line, and the straight line forms a certain angle with the X-axis straight line. Thus, the irradiation range of the UV lamp 231 can be more comprehensive, and the sterilization effect thereof can be more balanced.

Referring to fig. 10, two sets of UV light assemblies 23 are provided on the cleaning tank 22 in the direction of the X-axis, and the UV light assemblies 23 are arranged gradually away from the cleaning tank 22 in the direction from both ends of the cleaning tank 22 to the center of the cleaning tank 22. Referring to the view direction of fig. 10, the left UV light assembly 23 is located closer to the cleaning tank 22 at the left end thereof, and located farther from the cleaning tank 22 at the right end thereof, that is, the UV light assembly 23 is obliquely disposed such that the UV lamps on the UV light assembly 23 are disposed gradually away from the cleaning tank 22 in a direction from the end of the cleaning tank 22 to the center of the cleaning tank 22. The arrangement of the right-hand UV light assembly 23 is the same as it is and will not be described in detail here.

In this way, the number of UV lamps 231 provided on the lamp panel 232 is reduced compared to the number of UV lamps 231 used for one set of UV light assemblies 23 while ensuring that the light emitted by the UV lamps 231 can cover at least part of the surface of the roll brush 13 in the X-axis direction. This is because the farther the UV lamp 231 is from the cleaning tank 22, the larger the irradiation area of the UV lamp 231 is, so that the manufacturing cost of the apparatus can be reduced while guaranteeing the sterilization and cleaning of the UV light assembly 23.

In one embodiment of the present disclosure, referring to fig. 4, a UV light assembly 23 may also be disposed on an inner wall of the accommodating portion 24, and when a cleaning accessory is placed in the accommodating portion 24, light emitted by the UV light assembly 23 located in the accommodating portion 24 can be irradiated onto the cleaning accessory, so as to implement sterilization and cleaning of the cleaning accessory.

The structure of the UV light assembly 23 is the same as that of the previous embodiments, and will not be described in detail herein. The UV light assembly 23 disposed inside the receiving portion 24 may be configured to be disposed around an inner wall of the receiving portion 24. The light emitted from the UV lamp 231 thus can be used to wrap around the cleaning accessory placed inside the accommodating portion 24, and to perform 360 ° all-round sterilization cleaning on the same.

Specifically, the UV light assemblies 23 disposed on the inner wall of the accommodating portion 24 are gradually disposed axially around the bottom of the inner wall of the accommodating portion 24 to the opening of the inner wall of the accommodating portion 24, that is, at least one UV lamp is disposed at different heights. In this way, the light emitted by the UV light assembly 23 can perform a thorough sterilization and cleaning of the equipment placed in the housing 24.

In another embodiment of the present disclosure, the UV light assembly 23 is configured to be vertically disposed on the inner wall of the receiving portion 24, and the UV light assembly 23 may be plural, for example, three, distributed on the circumferential side wall of the receiving portion 24, thereby comprehensively irradiating the accessories located in the receiving portion 24. The UV light assembly 23 is arranged in such a way that it is possible to sterilize and clean the cleaning accessory placed in the receiving portion 24, and a person skilled in the art can select the design according to the actual use requirement without any limitation.

Referring to fig. 3, a charging assembly 25 is further disposed on the base 21 of the base station 2, and the charging assembly 25 is, for example, a charging male head disposed on the base 21, and a charging female head disposed on the machine body 16; or the charging male head is arranged on the machine body 16, and the charging female head is arranged on the base 21.

In the case where the hand-held cleaning device 1 is placed on the base 21, the charging male can be connected with the charging female in a mating manner, charging the body assembly 15. Further, the charging assembly 25 can also limit the placement of the handheld cleaning device 1 with the base station 2.

Fig. 2 illustrates an example where the charging assembly 25 is a charging male that is configured to extend vertically upward or obliquely upward in one embodiment of the present disclosure. The hand-held cleaning device 1 is placed on the base 21 in a top-down manner, and the charging male head and the charging female head can be matched together in an up-down plug-in manner for charging. Further, only after the body 16 is lifted up, the charging male and female heads can be separated from each other, and charging is ended. In this way, the stability of the handheld cleaning appliance 1 after placement can be improved.

In this embodiment, the specific positions of the hand-held cleaning device 1 and the base station 2 after being placed together are limited by the positional relationship between the cleaning tank 22 and the rolling brush 13, the limiting part 211 and the roller 14, and the body assembly 15 and the charging assembly 25 located on the base 21, so that the stability between the hand-held cleaning device 1 and the base station 2 is ensured.

In addition to the cleaning system described above, the present disclosure also provides a base station 2 for placing a handheld cleaning device 1. The specific structure of the hand-held cleaning device 1 and the base station 2 has been described in detail in the foregoing, and will not be described in detail here.

Further, the present disclosure also provides a control method for controlling the above cleaning system. Specific steps and effects of the control method of the cleaning system of the present disclosure are described in detail below in connection with one embodiment.

When the hand-held cleaning appliance 1 is placed on the base station 2 from top to bottom, the roller brush 13 in the brush assembly 11 is at least partially located in the cleaning tank 22 of the base station 2. And since the brush bristle state of the roller brush 13 in the dry and wet states is different, the roller brush 13 may be configured such that the surface is disposed in line contact with the groove bottom 221 of the cleaning groove 22, mainly in the state of the roller brush 13 in the dry state. Thereby ensuring that the negative pressure formed between the hand-held cleaning device 1 and the cleaning tank 22 is sufficiently large that the main motor can suck away the liquid at the cleaning tank 22.

The roller 14 in the floor brush assembly 11 is at least partially located in a limit 211 on the base 21 of the base station 2. The charging assembly 25 on the body 16 is cooperatively connected with the charging assembly 25 on the base 21 of the base station 2.

At this time, the hand-held cleaning device 1 may be started to perform a self-cleaning operation. During the self-cleaning operation, the water pump in the handheld cleaning device 1 controls the water tank to supply liquid to the area of the roller brush 13, so that the roller brush 13 can be cleaned in the cleaning tank 22. The rolling brush 13 is in a wet state after receiving water, or the rolling brush 13 is in a wet state after working, a certain gap is reserved between the cleaning tank 22 and the rolling brush 13 in the wet state, so that the rolling brush 13 can smoothly rotate, and friction with the inner wall of the cleaning tank 22 is avoided. In addition, at least part of the rolling brush 13 is positioned in the cleaning tank 22, so that the sewage left by the rolling brush 13 in the self-cleaning rotation process can enter the cleaning tank 22, and the sewage is prevented from being thrown out when the rolling brush 13 rotates.

After the water tank stops supplying water to the roller brush 13, the cleaning device 1 controls the UV light assembly 23 to start to operate, and the light emitted by the UV light assembly 23 can pass through the through holes formed in the cleaning tank 22 and irradiate at least part of the surface of the roller brush 13. The surface of the rolling brush 13 is irradiated by the UV light assembly 23, so that the surface of the rolling brush 13 is sterilized and cleaned. Therefore, bacterial communities attached to the rolling brush 13 can be effectively eliminated, the use time limit of the cleaning system is prolonged, and the use requirements of users are met.

The time at which the UV light assembly 23 is turned on may be at any time when the water tank stops supplying water to the roller brush 13. For example, in one embodiment of the present disclosure, the UV light assembly 23 may be controlled to be turned on after the water pump is stopped, the UV light assembly 23 may be turned on after the main motor sucks the sewage in the cleaning tank 22, or the UV light assembly 23 may be controlled to be turned on during a self-cleaning final spin-drying stage, and the water pump is stopped during the self-cleaning spin-drying stage, the main motor and the spin-brush motor are operated, the spin-brush motor drives the spin-brush to rotate, the main motor is operated to generate suction, and the UV light assembly 23 sterilizes the rotating spin-brush.

As shown in table 1, table 1 is a complete self-cleaning flow example, and UV light assembly 23 may be turned on at stages B1, B2, B3, and B4 as shown below; or the UV light assembly 23 is turned on in stages B3, B4; or the UV light assembly is turned on only during the final B4 drying stage.

The following describes the technical scheme adopted by the present disclosure in connection with a specific application scenario, so as to help understanding. The cleaning device 1 is not limited to a hand-held cleaning device, but may be a self-walking cleaning device. In the following application scenario, the cleaning device 1 is described in terms of a hand-held floor scrubber.

Application scenario 1

In the cleaning system, the hand-held floor washer (hereinafter referred to as a floor washer) includes a body assembly 15, a floor brush assembly 11 rotatably coupled to the body assembly 15, and a base station 2 for receiving the floor washer. When the user does not need to use the floor washer, the floor washer can be placed onto the base station 2 from top to bottom. The floor washer cooperates with the base 21 of the base station 2 to enable stable placement of the floor washer. Avoid unnecessary damage caused by toppling or rotation of the floor washing machine.

Specifically, after the user places the floor scrubber on the base station 2 from top to bottom, the roller brush 13 in the floor brush assembly 11 is matched with the cleaning tank 22 arranged on the base 21 of the base station 2, the roller 14 is matched with the limiting part 211, and the charging assembly 25 on the machine body 16 is matched with the charging assembly 25 on the base 21. Through the multi-aspect limit fit, the floor cleaning machine can be stably placed.

In the case where the floor scrubber is placed in the base 21, the user may choose to manually turn on or the cleaning system automatically turns on the self-cleaning function. The water pump in the housing assembly 15 is now able to control the water tank to supply liquid to the area of the roller brush 13. The rolling brush 13 can rotate under the control of a motor and is matched with the water supplied by the water tank of the cleaning tank 22 to clean the water. Meanwhile, the sewage left in the rotating process of the rolling brush 13 can directly enter the cleaning tank 22, so that the sewage is prevented from being thrown out when the rolling brush 13 rotates. The main motor inside the cleaning system sucks the sewage in the cleaning tank 22 into the sewage tank by the negative pressure formed between the hand-held cleaning device 1 and the cleaning tank 22. By repeating the above steps, the water cleaning of the roll brush 13 is achieved.

After the water tank stops supplying water, the roller brush 13 continues to rotate, and the main motor continues to maintain the suction state to air-dry the roller brush 13. At this time, the UV light assembly 23 operates to emit UV light and irradiate onto a portion of the surface of the roller brush 13 to sterilize and clean the roller brush 13. Since there is a certain gap between the surface of the roller brush 13 and the lamp housing 234 when in a wet state, UV light can be irradiated onto more surface of the roller brush 13 through the gap. As the roller brush 13 rotates, UV light may be repeatedly irradiated to the surface of the roller brush 13. After a preset time, the self-cleaning function is ended.

At this time, the rolling brush 13 can be effectively cleaned comprehensively and thoroughly by water cleaning and sterilization cleaning. The cleaned rolling brush 13 has better cleaning capability, and bacterial communities attached to the rolling brush 13 are largely eliminated, so that peculiar smell and mildew can be avoided. Finally, the use time limit of the rolling brush 13 can be prolonged, and the use experience of a user is improved.

Application scenario 2

In this application scenario, the other is the same as the above embodiment, except that after the user manually starts or the cleaning system automatically starts self-cleaning, the starting operation time of the UV light assembly 23 is the time when the water pump is not working in the self-cleaning process. That is, as long as the water pump does not control the water tank to supply water to the area where the roller brush 13 is located, the UV light assembly 23 is turned on to irradiate the surface of the roller brush 13, and a sterilization and cleaning function is performed. Therefore, the self-cleaning time of the cleaning system can be greatly shortened, and the use experience of a user is effectively improved.

The foregoing description of the embodiments of the present disclosure has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the various embodiments described. The terminology used herein was chosen in order to best explain the principles of the embodiments, the practical application, or the technical improvements in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein. The scope of the present disclosure is defined by the appended claims.
