Figure 3 It is a structural diagram of an embodiment of the present application.

[0035] In one embodiment, the cleaning system includes a cleaning device 10 and a tray 20. The cleaning device 10 may be a cleaning device such as a floor scrubber. The cleaning device 10 includes a main unit 11 and a floor brush 12 rotatably connected to the main unit 11. The floor brush 12 is used to clean the surface to be cleaned, and the surface to be cleaned may be the ground or the surface of an object to be cleaned. The embodiment of the present application is described by taking the surface to be cleaned as the ground as an example, which is only for the purpose of discussion and is not limited thereto. The floor brush 12 is also called a cleaning head or a suction head. The cleaning device 10 has a roller brush 122 for cleaning the surface to be cleaned, and the roller brush 122 is specifically arranged on the floor brush 12. The user holds the main unit 11 and pushes the floor brush 12 to move on the surface to be cleaned, and the roller brush 122 on the floor brush 12 can clean the area it passes through. The cleaning device 10 is used in conjunction with the tray 20, and the tray 20 has functions such as storage, charging, and self-cleaning. When the cleaning device 10 is placed on the tray 20 , the tray 20 can charge the cleaning device 10 , or the tray 20 can assist the cleaning device 10 in cleaning components including the roller brush 122 (ie, a self-cleaning function).

[0036] Please also read Figure 4 , Figure 4 yes Figure 1 The cross-sectional structure of the cleaning system is shown as a schematic diagram of an embodiment. The tray 20 of the embodiment of the present application is described below.

[0037] In one embodiment, the tray 20 has a first direction X and a second direction Y that are perpendicular to each other. The tray 20 includes a tray housing 21. The tray housing 21 has a receiving slot 211, and the receiving slot 211 has a receiving space extending along the second direction Y. When the cleaning device 10 is placed on the tray 20, the roller brush 122 is received in the receiving space of the receiving slot 211. The tray 20 also includes a drying component 22. The drying component 22 is disposed in the tray housing 21. The drying component 22 is used to heat and output a drying airflow, so as to output a drying airflow to the receiving slot 211, and then dry the roller brush 122 received in the receiving space of the receiving slot 211.

[0038] In the above manner, considering that the roller brush 122 is usually in a wet state after completing self-cleaning, which may easily lead to problems such as mold, bacterial growth, and odor, the drying component 22 of the tray 20 of this embodiment is used to output a drying airflow to the receiving groove 211 to dry the roller brush 122 received in the receiving groove 211. In other words, this embodiment can dry the roller brush 122 of the cleaning device 10 so that the roller brush 122 is kept as dry as possible, thereby avoiding problems such as mold, bacterial growth, and odor as much as possible.

[0039] In one embodiment, the tray shell 21 further has a receiving chamber 212, and the receiving chamber 212 and the receiving groove 211 are spaced apart from each other. The tray shell 21 further has an air outlet 213, and the receiving chamber 212 is communicated with the air outlet 213. The drying airflow in the tray shell 21 flows out to the outside of the tray shell 21 through the air outlet 213 to dry the roller brush 122 accommodated in the receiving space. The drying component 22 is accommodated in the receiving chamber 212. The drying airflow output by the drying component 22 is transmitted to the air outlet 213 in the receiving chamber 212, and is output to the receiving groove 211 through the air outlet 213 to dry the roller brush 122 accommodated in the receiving groove 211.

[0040] Specifically, the top of the tray housing 21 is recessed downward to form a receiving groove 211, and the receiving cavity 212 is located inside the tray housing 21. The tray housing 21 includes a first base 214 and a second base 215, and the second base 215 is convexly arranged on the top of the first base 214. The top of the first base 214 is recessed downward to form the receiving groove 211. The receiving groove 211 and the second base 215 are arranged opposite to each other along the first direction X, and the receiving groove 211 extends along the second direction Y. When the cleaning device 10 is accommodated in the tray 20, the host 11 is supported by the second base 215. The tray housing 21 is convexly provided with a first supporting portion 217 and a second supporting portion 216, that is, the first base 214 is convexly provided with a second supporting portion 216 and a first supporting portion 217. The second supporting portion 216 and the first supporting portion 217 are both adjacent to the receiving groove 211, and the second supporting portion 216 and the first supporting portion 217 are respectively located on different sides of the receiving groove 211. The first support portion 217 is protruded from at least one side of the receiving groove 211 in the second direction Y. Figure 2a and Figure 2b The first support portion 217 is exemplarily shown to be protruding from both sides of the receiving groove 211 in the second direction Y. The second support portion 216 is protruding from the side of the receiving groove 211 away from the second base portion 215. The second support portion 216 constitutes the side wall of the receiving groove 211. The second support portion 216 is provided with an air outlet 213 on the surface facing the receiving groove 211. Of course, in other embodiments of the present application, the first base portion 214 may also be provided with an air outlet 213 on the surface facing the receiving groove 211.

[0041] The tray 20 further includes a charging component, which is used to charge the cleaning device 10. The charging component is disposed on the second base 215 so that when the main body 11 of the cleaning device 10 is supported on the second base 215, the charging component is electrically connected to the main body 11 for charging. A portion of the accommodating cavity 212 is located in the first base 214, and the remaining portion is located in the second base 215. The accommodating cavity 212 in the second base 215 is connected to the air outlet 213 through the accommodating cavity 212 in the first base 214. At least a portion of the accommodating cavity 212 in the first base 214 is located at the bottom side of the accommodating groove 211, and at least a portion of the drying component 22 is located at the bottom side of the accommodating groove 211, that is, at least a portion of the drying component 22 is located in the at least a portion of the accommodating cavity 212 of the first base 214.

[0042] Furthermore, the drying component 22 includes an airflow output element 221 and a heating element 222. The airflow output element 221 is used to output airflow. The airflow output element 221 can be an element such as a fan or a blower 13 that can guide the airflow through the heating element 222. The heating element 222 can heat the airflow passing through it, and the heating element 222 can generate heat by itself to heat the airflow. The airflow output by the airflow output element 221 becomes a drying airflow after being heated by the heating element 222, and the drying airflow is output through the air outlet 213. At this time, the drying airflow with a higher temperature can dry the roller brush 122 accommodated in the accommodating groove 211.

[0043] The heating element 222 is located at the bottom of the receiving groove 211, that is, the heating element 222 is located in the receiving cavity 212 at the bottom of the receiving groove 211. The heating element 222 is arranged near the air outlet 213 relative to the airflow output element 221 to ensure that the airflow output by the airflow output element 221 can pass through the heating element 222, and further ensure that the heating element 222 can heat the airflow output by the airflow output element 221 to form a drying airflow. The airflow output element 221 is accommodated in the receiving cavity 212 in the first base 214 and / or the second base 215.

[0044] Furthermore, since the charging interface on the main unit 11 of the cleaning device 10 and the roller brush 122 are arranged in sequence along the direction of travel of the floor brush 12, the charging assembly of this embodiment is located on one side of the receiving groove 211, and the air outlet 213 is close to the side of the receiving groove 211 away from the charging assembly (the second support portion 216 mentioned above is similarly close to the side of the receiving groove 211 away from the charging assembly), so that when the cleaning device 10 is accommodated in the tray 20, the roller brush 122 is close to the air outlet 213, and the drying airflow output by the air outlet 213 can dry the roller brush 122 in the first time, with high drying efficiency, and the charging interface on the main unit 11 can be docked with the charging assembly for charging. The second base 215 is located on one side of the receiving groove 211, and the air outlet 213 is close to the side of the receiving groove 211 away from the second base 215. The airflow output element 221 is arranged close to the charging assembly relative to the heating element 222, and the accommodating cavity 212 near the charging assembly has sufficient space for arranging the airflow output element 221.

[0045] In one embodiment, the cleaning device 10 further includes a fan 13 and a recovery pipeline. The fan 13 is disposed on the main unit 11. The recovery pipeline has an inlet and an outlet, the inlet is disposed on the floor brush 12, and the outlet is disposed on the main unit 11. The fan 13 guides the drying airflow to flow through the roller brush 122, enters the recovery pipeline from the inlet, and flows out from the outlet.

[0046] Specifically, the cleaning device 10 further includes a recovery component 14, which is provided on the main unit 11 and the floor brush 12. The recovery component 14 is used to recover and store dirt during the cleaning process, and the fan 13 is used to guide the drying airflow in the receiving groove 211 to enter the recovery component 14 after passing through the roller brush 122. Since dirt is usually in a moist state, the fan 13 of this embodiment guides the drying airflow into the recovery component 14, and the drying airflow can also dry the residual moisture inside the recovery component 14, so that the inside of the recovery component 14 can also be kept dry, so as to avoid problems such as mold, bacteria growth, and odor as much as possible. It should be noted that in the embodiment of the present application, on the basis of the drying component 22 outputting drying airflow to the roller brush 122, the fan 13 draws the drying airflow into the recovery component 14, and the fan 13 cooperates with the drying component 22 to fully drive the drying airflow through the roller brush 122, so that the flow rate of the drying airflow is increased, and the heat can be efficiently conducted to the roller brush 122, thereby efficiently drying the roller brush 122, so that the roller brush 122 dries quickly, reducing the risk of the roller brush 122 becoming mildewed and breeding bacteria.

[0047] The recycling component 14 includes a recycling barrel 141. The recycling barrel 141 has a dirt collecting chamber 142 inside, and the dirt collecting chamber 142 is used to store the dirt recovered by the recycling component 14. The recycling component 14 also includes a recycling pipe 143. The recycling pipe 143 is arranged in the dirt collecting chamber 142, one end of the recycling pipe 143 is connected to the recycling barrel 141, and the other end is in the dirt collecting chamber 142 and communicates with the dirt collecting chamber 142. The recycling component 14 also includes an absorption pipe 144. The floor brush 12 also includes a floor brush body 121, and a roller brush 122 is installed on the floor brush body 121. The floor brush body 121 is provided with a suction port 123 facing the roller brush 122, and the suction port 123 is the entrance of the above-mentioned recycling pipeline. A part of the absorption pipe 144 is in the floor brush body 121 and is communicated with the suction port 123, and the rest is in the host 11. During the cleaning process, the fan 13 draws air to create a negative pressure environment in the dirt collection chamber 142, so that the dirt is sucked into the suction port 123 under the action of the internal and external pressure difference. The dirt entering the suction port 123 passes through the absorption pipe 144 and the recovery pipe 143 in turn and finally converges in the dirt collection chamber 142. In the process of drying the roller brush 122, the airflow output element 221 outputs airflow to the heating element 222. The airflow output by the airflow output element 221 becomes a drying airflow after being heated by the heating element 222. The drying airflow is output through the air outlet 213. At this time, the drying airflow with a higher temperature can dry the roller brush 122 accommodated in the accommodation groove 211. The fan 13 draws air to create a negative pressure environment in the dirt collection chamber 142, so that the drying airflow enters the absorption pipe 144 under the action of the internal and external pressure difference. The drying airflow can dry the residual moisture inside the absorption pipe 144, so that the inside of the absorption pipe 144 can also be kept dry to avoid mold, bacteria, odor and other problems as much as possible. The recycling assembly 14 may also include a filter, which is disposed on the top of the recycling barrel 141. The fan 13 guides the drying airflow through the filter, and the dirt carried by the drying airflow due to contact with the roller brush 122 can be filtered and removed by the filter. The drying airflow filtered by the filter is discharged into the surrounding environment through the gap between the recycling barrel 141 and the main unit 11.

Figure 7 yes Figure 5 Schematic diagram of the structure of the cleaning system N area.

[0049] In one embodiment, the tray 20 also includes a seal 24, which is disposed on the tray shell 21. The seal 24 is used to reduce the gap between the floor brush 12 and the tray 20. That is, a seal is formed by the seal 24, which can reduce the escape of drying airflow, thereby improving the drying efficiency of the roller brush and reducing the risk of dirt escaping with the drying airflow.

[0050] Specifically, the seal formed by the seal 24 in the embodiment of the present application includes two situations. First, when the cleaning device 10 is contained in the tray 20, there may be a small gap between the seal 24 and the floor brush 12, and the gap width may be 1mm to 5mm. At this time, the drying airflow escaping from the gap between the seal 24 and the floor brush 12 is small, and most of the drying airflow is recovered by the recovery component 14, so that when the user picks up the cleaning device 10 from the tray 20, the cleaning device 10 will not lift the tray 20; second, when the cleaning device 10 is contained in the tray 20, there is no gap between the seal 24 and the floor brush 12, that is, the seal 24 and the floor brush 12 form a tight seal, which minimizes the risk of drying airflow escaping, and at this time, the seal 24 and the floor brush 12 can be matched by interference fit or the like.

[0051] In one embodiment, the sealing member 24 includes a first sealing member 241 and a second sealing member 242. The first sealing member 241 is disposed on at least one side of the receiving groove 211 in the second direction Y. Figure 2a and Figure 2b It is exemplarily shown that the first seal 241 is arranged on both sides of the receiving groove 211 in the second direction Y. The second seal 242 is arranged on one side of the receiving groove 211 in the first direction X. The first seal 241 and the second seal 242 are both used to reduce the gap between the floor brush 12 and the tray 20 when the cleaning device 10 is accommodated in the tray 20. The floor brush 12 also has a third seal (including the scraper strip 15 described below), specifically, the third seal is arranged on the floor brush body 121. The third seal is on the side of the floor brush 12 facing the surface to be cleaned, and the third seal is behind the roller brush 122 in the direction of travel of the floor brush 12. When the cleaning device 10 is accommodated in the tray 20, the third seal is used to reduce the gap between the floor brush 12 and the tray 20.

[0052] Through the above method, in this embodiment, when the cleaning device 10 is accommodated in the tray 20, the first seal 241 can reduce the gap between the two sides of the floor brush 12 and the tray 20, the second seal 242 can reduce the gap between the front end of the floor brush 12 and the tray 20, and the third seal can reduce the gap between the rear end of the floor brush 12 and the tray 20. In this way, all-round sealing can be performed to avoid the escape of drying airflow as much as possible. The drying airflow is sucked away from the suction port 123 by the fan 13, thereby improving the drying efficiency of the roller brush 122 and reducing the risk of dirt escaping with the drying airflow.

[0053] In one embodiment, the first seal 241 is disposed on a side of the first support portion 217 facing the receiving groove 211. When the cleaning device 10 is accommodated in the tray 20, at least a portion of the floor brush 12 (specifically, a portion close to the roller brush 122) is located between the first support portions 217, that is, in the second direction Y, the first seal 241 is located between the floor brush 12 and the first support portion 217. In this way, when the cleaning device 10 is accommodated in the tray 20, the first seal 241 can reduce the gap between the two sides of the floor brush 12 and the tray 20, which can not only prevent dirt from splashing out of the tray 20 as much as possible during the self-cleaning process of the cleaning device 10, but also prevent the drying airflow carrying dirt due to contact with the roller brush 122 from entering the recovery component 14 and being directly discharged into the surrounding environment as much as possible during the drying process of the roller brush 122, which is conducive to ensuring that the user's daily home environment is clean and tidy, and is beneficial to the user's personal health. Here, the side wall of the floor brush 12 may be the side wall of the floor brush 12 housing, or may be the side wall of the roller brush 122 located on the side of the floor brush 12, the side wall of the roller brush handle, the side wall of the roller brush cover, etc.

[0054] When the cleaning device 10 is accommodated in the tray 20, the first support portion 217 is close to the end of the roller brush 122. The first support portion 217 is used to block the dirt generated during the self-cleaning process and the drying airflow carrying the dirt, and to prevent the dirt from escaping outward from the end of the roller brush 122 as much as possible. Therefore, the first support portions 217 are respectively provided on the opposite sides of the receiving groove 211 to correspond to the two opposite ends of the roller brush 122. The surface of each first support portion 217 facing the receiving groove 211 is provided with a first sealing member 241, which further reduces the risk of dirt escaping outward from the end of the roller brush 122.

[0055] Furthermore, the floor brush 12 further includes a cover 124, which is located on the side of the roller brush 122 away from the surface to be cleaned, that is, the cover 124 is located on the upper side of the roller brush 122. The inner wall of the cover 124 facing the roller brush 122 has an arc-shaped profile similar to the surface of a cylindrical roller brush. In this embodiment, the position of the cover 124 is higher than the roller brush 122, and the first seal 241 is arranged on the first support portion 217, so that the first seal 241 can match the side profile of the cover 124, so that the first seal 241 forms a seal with the outer side wall of the cover 124 or with the inner wall of the cover 124 facing the roller brush 122. Furthermore, at least a portion of the first seal 241 is away from the first base 214 relative to the second seal 242, that is, at least a portion of the first seal 241 is located on the upper side of the roller brush 122 to be arranged opposite to the cover 124, so that the first seal 241 cooperates with the cover 124 to form a seal, and further enables the first seal 241 to easily form a seal with the outer wall or inner wall of the cover 124. In order to fit the outer wall or inner wall of the cover 124, the first seal 241 itself has an arc-shaped profile that arches in a direction away from the tray housing 21 (i.e., arches upward), that is, an arc-shaped profile that arches in a direction away from the first base 214.

[0056] The reason why the floor brush 12 needs to be sealed on the side in the embodiment of the present application is that the two sides of the roller brush 122 are open and are not covered by the housing or cover 124 of the floor brush 12. This has the advantage of making it easier to clean the roller brush 122 against the edge without the obstruction of the housing. Since the two sides of the roller brush 122 are open, in order to prevent the drying airflow from flowing out from both sides, the first sealing member 241 is provided on both sides of the floor brush 12.

[0057] Furthermore, the first sealing member 241 includes a first sealing sub-portion 243 and a second sealing sub-portion 244. The first sealing sub-portion 243 is away from the first base 214 relative to the second sealing sub-portion 244, the second sealing sub-portion 244 is located on the side of the first sealing sub-portion 243 away from the second sealing member 242, and the second sealing sub-portion 244 connects the first sealing sub-portion 243 and the first base 214. The function of the second sealing sub-portion 244 is to connect the first base 214 and other sealing members higher than the first base 214, such as the first sealing sub-portion 243, so as to achieve complete sealing of the side of the floor brush 12. When the cleaning device 10 is accommodated in the tray 20, the side of the floor brush 12 is sealed with the first supporting portion 217 through the first sealing member 241. Specifically, the first sealing sub-portion 243 is used to form a seal at the top of the space between the floor brush 12 and the first support portion 217 to prevent dirt from escaping upward in the direction away from the bottom of the accommodating groove 211; the first sealing sub-portion 243 is bent in the direction away from the first base 214, that is, the first sealing sub-portion 243 is arc-shaped to match the shape of the cover body 124; the second sealing sub-portion 244 is used to form a seal at the rear of the space between the floor brush 12 and the first support portion 217 to prevent dirt from escaping backward in the direction away from the second support portion 216.

[0058] Optionally, the first seal 241 and the second seal 242 may be sealing soft rubber, etc., and the floor brush 12 and the first seal 241 and the second seal 242 may be sealed by interference fit. In addition, the first sealing sub-section 243 may include at least two sub-sections, each of which is spaced apart along the first direction X, that is, the first sealing sub-section 243 adopts a segmented design, which can facilitate the processing and molding process of the first sealing sub-section 243.

[0059] In one embodiment, the second sealing member 242 is disposed on the second supporting portion 216, specifically, the second sealing member 242 is located at the top of the second supporting portion 216 away from the first base portion 214. When the cleaning device 10 is accommodated in the tray 20, the second sealing member 242 is located on a side of the cover 124 close to the first base portion 214, and the cover 124 abuts against the second sealing member 242 under at least the action of gravity to form a seal, such as Figure 6 As shown. In this way, when the user removes the cleaning device 10 from the tray 20, the risk of the tray 20 being lifted by the cleaning device 10 can be reduced. Of course, in other embodiments of the present application, additional means such as magnetic attraction can be added to make the cover 124 and the second support portion 216 cooperate to squeeze the second sealing member 242, which is not limited here.

[0060] Through the above-mentioned method, in this embodiment, when the cleaning device 10 is accommodated in the tray 20, a seal is formed between the cover body 124 and the second support portion 216 through the second sealing member 242, which can not only prevent dirt from splashing out of the tray 20 during the self-cleaning process of the cleaning device 10, but also prevent the drying airflow carrying dirt due to contact with the roller brush 122 from entering the recovery component 14 and being directly discharged into the surrounding environment during the drying process of the roller brush 122, which is beneficial to ensuring that the user's daily home environment is clean and tidy and is beneficial to the user's personal health.

[0061] In one embodiment, the third sealing member includes a scraper bar 15. The scraper bar 15 is convexly disposed on the bottom surface of the floor brush body 121, and the scraper bar 15 is located behind the roller brush 122 in the direction of travel of the floor brush 12. During the cleaning process, the scraper bar 15 is used to block the dirt from moving to the rear of the direction of travel of the floor brush 12 to ensure that the dirt is recovered as much as possible by the suction port 123 on the floor brush body 121, thereby ensuring the cleaning effect. In this embodiment, when the cleaning device 10 is accommodated in the tray 20, the scraper bar 15 is used to block the drying airflow to prevent the drying airflow from passing through the scraper bar 15 and being unable to be absorbed by the recovery component 14, thereby preventing the drying airflow carrying dirt from being directly discharged into the surrounding environment, which is beneficial to ensuring that the user's daily home environment is clean and tidy, and is beneficial to the user's personal health.

[0062] Furthermore, when the cleaning device 10 is accommodated in the tray 20, the scraper bar 15 can be close to the bottom of the receiving groove 211 to cooperate with the bottom of the receiving groove 211 to form a seal, thereby improving the effect of blocking the drying airflow and further preventing the drying airflow from being directly discharged into the surrounding environment through the scraper bar 15. Figure 7 shown.

[0063] It should be noted that, in this embodiment, a seal is formed between the side wall of the floor brush 12 and the first support portion 217 through the first sealing member 241, a seal is formed between the cover body 124 of the floor brush 12 and the second support portion 216 through the second sealing member 242, and a seal is formed between the bottom of the floor brush body 121 through the scraper strip 15 and the bottom of the accommodating groove 211. Combined with the cover body 124, the roller brush 122 is sealed in all directions, which can prevent the drying airflow from escaping as much as possible. The drying airflow is sucked away from the suction port 123 by the fan 13, thereby improving the drying efficiency of the roller brush 122 and reducing the risk of dirt escaping with the drying airflow. The dirt generated during the self-cleaning process and the dry airflow carrying moisture and dirt can only be recovered to the recovery component 14 through the suction port 123, which not only prevents the dirt from splashing out of the tray 20 during the self-cleaning process of the cleaning device 10, but also prevents the dry airflow carrying dirt due to contact with the roller brush 122 from entering the recovery component 14 during the drying process of the roller brush 122 and being directly discharged into the surrounding environment, which is beneficial to ensuring that the user's daily home environment is clean and tidy and is beneficial to the user's personal health.

[0064] In one embodiment, the cleaning device 10 further includes a driving member (not shown). The driving member is disposed on the floor brush body 121, and is in transmission connection with the roller brush 122. The driving member is used to drive the roller brush 122 to rotate around its own axis, so that the rotating roller brush 122 performs cleaning work. The driving member can be a power element such as a motor, which is not limited here.

[0065] During the process of drying the roller brush 122, the driving member is also used to drive the roller brush 122 to rotate forward and reversely. That is, the roller brush 122 rotates forward for a period of time and reversely for a period of time. In this way, under the impact of the drying airflow, combined with the forward and reverse rotation of the roller brush 122, the fluff on the roller brush 122 can be combed. At the same time, the fluff on the roller brush 122 can also be broken up, thereby increasing the contact area between the fluff and the drying airflow, which is beneficial to improving the drying efficiency of the roller brush 122. Similarly, for the self-cleaning condition of the roller brush 122, the cleaning device 10 outputs cleaning liquid (such as clean water, etc.) to the roller brush 122 to clean the roller brush 122, and then the driving member drives the roller brush 122 to rotate for centrifugal air drying. The driving member can also drive the roller brush 122 to rotate forward and reverse, which can achieve the effect of combing the fluff on the roller brush 122, and can also break up the fluff on the roller brush 122, increasing the contact area between the fluff and the cleaning liquid, which is beneficial to improving the cleaning efficiency and cleaning effect of the roller brush 122, thereby increasing the service life of the roller brush 122. It should be noted that Figure 4 The forward rotation of the middle roller brush 122 may be clockwise, and the reverse rotation of the roller brush 122 may be counterclockwise, or the forward rotation of the roller brush 122 may be counterclockwise, and the reverse rotation of the roller brush 122 may be clockwise, which is not limited here.

[0066] If the roller brush 122 only rotates in one direction for cleaning or self-cleaning, over time, the fluff on the roller brush 122 is very likely to stick to the roller brush 122 in the same direction, making it difficult for the cleaning liquid for auxiliary cleaning to penetrate into the deep fluff, resulting in a decrease in the cleaning effect of the roller brush 122 and a shortened service life of the roller brush 122.

[0067] Furthermore, the cleaning device 10 also includes a scraper 16. The scraper 16 is provided on the floor brush body 121, and the scraper 16 abuts against the roller brush 122. In the process of drying the roller brush 122, the scraper 16 has an interference fit with the roller brush 122, and the scraper 16 can cooperate with the forward and reverse rotation of the roller brush 122 to comb and break up the fluff on the roller brush 122, further increasing the contact area between the fluff and the drying airflow, which is further beneficial to improve the drying efficiency of the roller brush 122. For the self-cleaning working condition of the roller brush 122, the scraper 16 has an interference fit with the roller brush 122, and the scraper 16 can cooperate with the forward and reverse rotation of the roller brush 122 to comb and break up the fluff on the roller brush 122, further increasing the contact area between the fluff and the cleaning liquid, which is beneficial to improve the cleaning efficiency and cleaning effect of the roller brush 122.

[0068] Figure 6 The scraper 16 is shown as being located above the suction port 123. During the cleaning process of the cleaning device 10, the scraper 16 and the roller brush 122 are in interference fit, and the scraper 16 can scrape off the dirt on the roller brush 122, while the suction port 123 sucks the dirt scraped off by the scraper 16 into the recovery component 14. Similarly, for the self-cleaning condition of the roller brush 122, the scraper 16 and the roller brush 122 are in interference fit, and the scraper 16 can scrape off the dirty cleaning liquid on the roller brush 122, while the suction port 123 sucks the dirty cleaning liquid scraped off by the scraper 16 into the recovery component 14.

[0069] In one embodiment, the tray 20 further includes comb teeth 25. The comb teeth 25 are disposed in the receiving groove 211. When the cleaning device 10 is received in the tray 20, the comb teeth 25 abut against the roller brush 122. In the process of drying the roller brush 122, the comb teeth 25 are interference fit with the roller brush 122. The comb teeth 25 can comb and break up the fluff on the roller brush 122, increase the contact area between the fluff and the drying airflow, and help improve the drying efficiency of the roller brush 122. Figure 5 For the self-cleaning operation of the roller brush 122 , the comb teeth 25 are interference fit with the roller brush 122 , and the comb teeth 25 can comb and break up the fluff on the roller brush 122 , thereby increasing the contact area between the fluff and the cleaning liquid, which is beneficial to improving the cleaning efficiency and cleaning effect of the roller brush 122 .

[0070] The comb teeth 25 are arranged near the air outlet 213 in the receiving groove 211, which means that when the cleaning device 10 is accommodated in the tray 20, the air outlet 213 and the comb teeth 25 are arranged near the roller brush 122. In this way, the air outlet 213 is arranged near the roller brush 122, and the drying airflow output from the air outlet 213 can dry the roller brush 122 in time, which can ensure the drying efficiency of the roller brush 122, and the comb teeth 25 are arranged near the roller brush 122, so that the comb teeth 25 can reliably fit with the roller brush 122 in an interference fit, so as to achieve the effect of combing and breaking up the fluff on the roller brush 122. There are multiple comb teeth 25, and each comb tooth 25 is spaced in sequence along the second direction Y, so as to further ensure the effect of combing and breaking up the fluff on the roller brush 122 by the comb teeth 25.

[0071] Please also read Figure 8 , Figure 8 It is a structural schematic diagram of another embodiment of the tray of the present application.

[0072] In one embodiment, the area where the air outlet 213 on the tray 20 is located is divided into a first area 20a and a second area 20b and a third area 20c located on both sides of the first area 20a along the second direction Y, and the suction port 123 is arranged opposite to the first area 20a. The total flow area of ​​the air outlet 213 in the first area 20a is A1, the total flow area of ​​the air outlet 213 in the second area 20b is A2, and the total flow area of ​​the air outlet 213 in the third area 20c is A3, satisfying: A2<A1≤1.9A2, A3<A1≤1.9A3, or A2+A3≤A1≤1.9(A2+A3). In this way, this embodiment further helps to improve the drying uniformity of different positions of the roller brush 122 by reasonably setting the flow areas of the air outlet 213 in the first area 20a, the second area 20b and the third area 20c. Typically, the suction port 123 is located in the middle of the floor brush 12, so the first area 20a is also located in the middle of the area where the air outlet 213 is located on the tray 20. Of course, in other embodiments of the present application, the suction port 123 can also be arranged relative to other positions of the roller brush 122, which is not limited here.

[0073] The technical solution provided in the embodiments of the present application is described below in conjunction with specific application scenarios.

[0074] Application scenario 1:

[0075] The cleaning device 10 is a floor scrubber, and the cleaning device 10 is equipped with a tray 20. When the cleaning device 10 is accommodated in the tray 20, a seal is formed between the side wall of the floor brush 12 and the first support portion 217 through the first seal 241, a seal is formed between the cover 124 of the floor brush 12 and the second support portion 216 through the second seal 242, and a seal is formed between the bottom of the floor brush body 121 through the scraper strip 15 and the bottom of the receiving groove 211, and then combined with the cover 124, the roller brush 122 is fully sealed, which can prevent the drying airflow from escaping as much as possible, and the drying airflow is sucked away from the suction port 123 by the fan 13, thereby improving the drying efficiency of the roller brush 122 and reducing the risk of dirt escaping with the drying airflow. The dirt generated during the self-cleaning process and the dry airflow carrying moisture and dirt can only be recovered to the recovery component 14 through the suction port 123, which not only prevents the dirt from splashing out of the tray 20 during the self-cleaning process of the cleaning device 10, but also prevents the dry airflow carrying dirt due to contact with the roller brush 122 from entering the recovery component 14 during the drying process of the roller brush 122 and being directly discharged into the surrounding environment, which is beneficial to ensuring that the user's daily home environment is clean and tidy and is beneficial to the user's personal health.

[0076] Application scenario 2:

[0077] The cleaning device 10 is a floor scrubber, and the cleaning device 10 is equipped with a tray 20. When the cleaning device 10 is accommodated in the tray 20, the user outputs a self-cleaning instruction to the cleaning device 10 by pressing a self-cleaning button or the like, and the cleaning device 10 performs a self-cleaning operation in response to the instruction. Specifically, the water pump of the cleaning device 10 pumps clean water to the roller brush 122, and the roller brush 122 rotates forward and reverse in the clean water to clean the dirt attached thereto; after the roller brush 122 completes self-cleaning, the fan 13 on the main unit 11 works to suck the sewage in the tray 20 into the recovery component 14, and at the same time, the scraper 16 on the floor brush 12 scrapes off the sewage remaining on the roller brush 122 and sucks it into the recovery component 14 by the fan 13. During this process, the heating element 222 of the drying component 22 can be preheated.

[0078] After completing the self-cleaning operation, the cleaning device 10 enters the centrifugal air-drying mode. The airflow output element 221 of the drying component 22 works to output airflow to the heating element 222. The heating element 222 can heat the airflow passing through it. The airflow output by the airflow output element 221 becomes a drying airflow after being heated by the heating element 222. The drying airflow is output through the air outlet 213 on the tray 20. At this time, the drying airflow with a higher temperature can dry the roller brush 122 accommodated in the accommodating groove 211. At the same time, the driving member drives the roller brush 122 to keep rotating for centrifugal air-drying. On the basis of the drying component 22 outputting drying airflow to the roller brush 122, the fan 13 draws the drying airflow into the recovery component 14, and the drying airflow is discharged after being filtered by the filter element. The fan 13 cooperates with the drying component 22 to fully drive the drying airflow to pass through the roller brush 122, so that the flow rate of the drying airflow is increased, and the heat can be efficiently transferred to the roller brush 122, thereby efficiently drying the roller brush 122, so that the roller brush 122 dries quickly, reducing the risk of the roller brush 122 becoming mildewed and breeding bacteria.

[0079] During the centrifugal drying process, a drying airflow enters the recovery component 14, and the drying airflow can also dry the residual moisture in the internal pipe of the recovery component 14, so that the internal pipe of the recovery component 14 can also remain dry to avoid problems such as mold, bacteria growth, and odor as much as possible.

[0080] Application scenario three:

[0081] The cleaning device 10 is a floor scrubber, and the cleaning device 10 is equipped with a tray 20. When the cleaning device 10 is accommodated in the tray 20, a seal is formed between the front of the floor brush 12 and the second support portion 216 on the tray 20 through the first seal 241, a seal is formed between the side wall of the floor brush 12 and the first support portion 217 through the second seal 242, and a seal is formed between the bottom of the floor brush 12 through the scraper bar 15 and the bottom of the receiving groove 211. The dirt generated during the self-cleaning process and the dry airflow carrying moisture and dirt can only be recovered to the recovery component 14 through the suction port 123, which can not only prevent dirt from splashing out of the tray 20 during the self-cleaning process of the cleaning device 10, but also prevent the dry airflow carrying dirt due to contact with the roller brush 122 from entering the recovery component 14 and being directly discharged into the surrounding environment during the drying process of the roller brush 122, which is conducive to ensuring that the user's daily home environment is clean and tidy, and is beneficial to the user's personal health.

[0082] The user outputs a self-cleaning instruction to the cleaning device 10 by pressing a self-cleaning button or the like, and the cleaning device 10 performs a self-cleaning operation in response to the instruction. When the cleaning device 10 enters the centrifugal air-drying mode, the airflow output element 221 of the drying component 22 works to output airflow to the heating element 222. The heating element 222 can heat the airflow passing through it, and the airflow output by the airflow output element 221 becomes a drying airflow after being heated by the heating element 222. The drying airflow is output through the air outlet 213 on the tray 20. At this time, the drying airflow with a higher temperature can dry the roller brush 122 accommodated in the accommodation groove 211, and at the same time, the driving member drives the roller brush 122 to keep rotating for centrifugal air-drying. On the basis of the drying component 22 outputting drying airflow to the roller brush 122, the fan 13 draws the drying airflow into the recovery component 14, and the drying airflow is discharged after being filtered by the filter element. The fan 13 cooperates with the drying component 22 to fully drive the drying airflow to pass through the roller brush 122, so that the flow rate of the drying airflow is increased, and the heat can be efficiently transferred to the roller brush 122, thereby efficiently drying the roller brush 122, so that the roller brush 122 dries quickly, reducing the risk of the roller brush 122 becoming mildewed and breeding bacteria.

[0083] Application scenario 4:

[0084] The cleaning device 10 is a floor scrubber, and the cleaning device 10 is equipped with a tray 20. When the cleaning device 10 is accommodated in the tray 20, the user outputs a self-cleaning instruction to the cleaning device 10 by pressing a self-cleaning button or the like, and the cleaning device 10 performs a self-cleaning operation in response to the instruction. Specifically, the water pump of the cleaning device 10 pumps clean water to the roller brush 122, and the roller brush 122 rotates forward and reverse in the clean water to clean the dirt attached thereto; after the roller brush 122 completes self-cleaning, the fan 13 on the main unit 11 works to suck the sewage in the tray 20 into the recovery component 14, and at the same time, the scraper 16 on the floor brush 12 scrapes off the sewage remaining on the roller brush 122 and sucks it into the recovery component 14 by the fan 13. During this process, the heating element 222 of the drying component 22 can be preheated.

[0085] After completing the self-cleaning operation, the cleaning device 10 enters the centrifugal air-drying mode. The airflow output element 221 of the drying component 22 works to output airflow to the heating element 222. The heating element 222 can heat the airflow passing through it. The airflow output by the airflow output element 221 becomes a drying airflow after being heated by the heating element 222. The drying airflow is output through the air outlet 213 on the tray 20. At this time, the drying airflow with a higher temperature can dry the roller brush 122 accommodated in the accommodating groove 211. At the same time, the driving member drives the roller brush 122 to keep rotating for centrifugal air-drying. On the basis of the drying component 22 outputting the drying airflow to the roller brush 122, the fan 13 draws the drying airflow into the recovery component 14, and the drying airflow is discharged after being filtered by the filter element. The fan 13 cooperates with the drying component 22 to fully drive the drying airflow through the roller brush 122, so that the flow rate of the drying airflow is increased, and the heat can be efficiently transferred to the roller brush 122, thereby efficiently drying the roller brush 122, so that the roller brush 122 is quickly dried, and the risk of the roller brush 122 being moldy and breeding bacteria is reduced. In the process of drying the roller brush 122, the scraper 16 is interference-fitted with the roller brush 122, and the scraper 16 can cooperate with the forward and reverse rotation of the roller brush 122 to comb and break up the fluff on the roller brush 122, so as to increase the contact area between the fluff and the drying airflow, which is conducive to improving the drying efficiency of the roller brush 122.

[0086] During the centrifugal drying process, a drying airflow enters the recovery component 14, and the drying airflow can also dry the residual moisture in the internal pipe of the recovery component 14, so that the internal pipe of the recovery component 14 can also remain dry to avoid problems such as mold, bacteria growth, and odor as much as possible.

[0087] Application scenario five:

[0088] The cleaning device 10 is a floor scrubber, and the cleaning device 10 is equipped with a tray 20. When the cleaning device 10 is accommodated in the tray 20, the user outputs a self-cleaning instruction to the cleaning device 10 by pressing a self-cleaning button, and the cleaning device 10 performs a self-cleaning operation in response to the instruction. The comb teeth 25 are interference-fitted with the roller brush 122, and the comb teeth 25 can comb and break up the fluff on the roller brush 122, thereby increasing the contact area between the fluff and the cleaning liquid, which is beneficial to improving the cleaning efficiency and cleaning effect of the roller brush 122.

[0089] After the cleaning device 10 completes the self-cleaning operation, it enters the centrifugal air-drying mode. The comb teeth 25 are interference-fitted with the roller brush 122, and the comb teeth 25 can comb and break up the fluff on the roller brush 122, increasing the contact area between the fluff and the drying airflow, so that the fluff on the roller brush 122 is fully in contact with the drying airflow, which is beneficial to improving the drying efficiency of the roller brush 122.
