Description

Technical Field

[0001] This application relates to the technical field of household appliances, and particularly relates to a surface cleaning system with a base. Background Art

[0002] To avoid the sewage bucket and / or cleaning parts of the surface cleaner from generating bacteria and emitting odors, cleaning liquid is usually added to clean and sterilize the sewage bucket and / or cleaning parts to inhibit the growth of bacteria. In the prior art, to reduce the body weight of the surface cleaner, the cleaning liquid component is usually arranged on the base for accommodating the surface cleaner, and the cleaning liquid is provided for the cleaning tank where the cleaning parts are placed through the liquid outlet arranged on the base. The cleaning tank and the cleaning parts are usually adhered with dirt, which is likely to block the liquid outlet, resulting in the cleaning liquid being ineffective and causing trouble to the user for cleaning. Summary of the Utility Model

[0003] The purpose of the embodiment of this application is to provide a base of a surface cleaning system, which can provide cleaning liquid to clean and deodorize the cleaner while reducing the risk of the liquid outlet being blocked by dirt.

[0004] This application provides a surface cleaning system with a base. The surface cleaning system includes a cleaner for cleaning a surface to be cleaned. The cleaner includes a cleaning part and a water supply component. A cleaning tank is arranged on the base. When the cleaner is placed on the base, the cleaning part is located in the cleaning tank. A cleaning liquid component is arranged on the base. The cleaning liquid component includes a liquid outlet nozzle arranged on the bottom wall of the cleaning tank, and the liquid outlet nozzle is provided with a liquid outlet facing the side wall of the cleaning tank.

[0005] Further, a scraping strip that is interference-fitted with the cleaning part is further arranged on the cleaner, and a water spraying plate is arranged above the scraping strip. The liquid on the water spraying plate flows into the cleaning tank along both ends of the scraping strip.

[0006] Further, the liquid outlet protrudes from the base through the liquid outlet nozzle, and the liquid outlet is arranged at the front edge of the scraping strip.

[0007] Further, the cleaning tank includes a first side wall and a second side wall that are oppositely arranged. The liquid outlet faces the first side wall and is arranged away from the central axis of the cleaning tank.

[0008] Further, there are at least two liquid outlets that face the first side wall and the second side wall respectively. The liquid outlet faces the first side wall and is arranged away from the central axis of the cleaning tank.

[0009] Further, there are at least two liquid outlets that face the first side wall and the second side wall respectively.

[0010] Further, the liquid outlet nozzle is arranged between the front edge of the scraping strip and the vertical projection of the central axis of the cleaning part.

[0011] Further, the cleaning liquid assembly includes a receiving cavity for receiving the cleaning liquid, a liquid inlet pipe communicating the receiving cavity and the liquid outlet unit, and the liquid outlet unit further includes a liquid outlet nozzle communicating with the liquid inlet pipe and a protective cover sleeved on the liquid outlet nozzle.

[0012] Further, the protective cover is an arc-shaped drainage plate facing the bottom of the cleaning tank.

[0013] Further, the liquid outlet unit is detachably installed on the base; alternatively, at least part of the cleaning tank is detachably installed on the base, and the liquid outlet unit is provided on the detachable cleaning tank.

[0014] Further, after the cleaning liquid and clean water are injected into the cleaning tank, the cleaning member rotates to mix the cleaning liquid and the clean water.

[0015] In the present application, the setting method of arranging the liquid outlet nozzle on the bottom wall of the cleaning tank and directing the liquid outlet towards the side wall of the cleaning tank not only meets the cleaning and deodorizing requirements of providing cleaning liquid for the cleaning tank, but also reduces the risk of the liquid outlet being blocked by dirt. Specifically, after the cleaning machine finishes cleaning the surface to be cleaned, the cleaning member is usually adhered with a certain amount of dirt. When placed on the base, the base, especially the cleaning tank for accommodating the cleaning member, will inevitably be contaminated, and even some of the dirt remaining in the dirt suction assembly will flow back into the cleaning tank as the placement time of the cleaning machine increases. The liquid outlet facing the cleaning tank is easily contaminated by dirt or blocked by dirt, affecting the liquid outlet. By arranging the liquid outlet nozzle on the bottom wall of the cleaning tank and directing it towards the side wall of the cleaning tank, the liquid outlet does not directly face the cleaning member or the bottom wall of the cleaning tank, reducing the risk of the liquid outlet being blocked.

[0033] Embodiment 1:

[0034] Please refer to Figure 1 , which is a schematic diagram of the structure of the surface cleaning system 1 shown in this application. Figure 2 , which is a schematic diagram of the first structure of the base 20 shown in this application. Figure 3 , which is a schematic diagram of the connection relationship between the components in the surface cleaning system 1 shown in this application. Figure 1 and Figure 3 As shown, the surface cleaning system 1 in this embodiment includes a cleaning machine 10; the cleaning machine 10 includes a pivotally connected body assembly 120 and a floor brush assembly 110; the floor brush assembly 110 is provided with a cleaning member 112 for cleaning the surface to be cleaned, a scraping bar for scraping the cleaning member 112, and a water spray plate; illustratively, the cleaning member 112 can be a single roller, a double roller or a crawler type cleaning cloth, or a combination of the above. The cleaning machine 10 also includes a dirt suction assembly, which includes a dirt suction port provided on the floor brush assembly 110 and facing the cleaning member 112, a sewage bucket 121 provided on the body assembly 120 for storing dirt, a dirt suction pipe connected to the dirt suction port and the sewage bucket 121, and a dirt suction fan 123 connected to the sewage bucket 121 for sucking dirt. The cleaning machine 10 also includes a water supply component, which includes a water spray port arranged on the water spray plate and facing the cleaning member 112, a clean water tank 122 for storing clean water, a liquid supply pipeline connected to the water spray port and the clean water tank 122, and a water pump 124 arranged on the liquid supply pipeline for conveying clean water.

[0035] like Figure 1 As shown, the surface cleaning system 1 further comprises a base 20. When the cleaning machine 10 is placed on the base 20, the base 20 can perform maintenance operations such as self-cleaning, drying and charging on the cleaning machine 10. Figure 2 As shown, a cleaning tank 21 is provided on the base 20 , and when the cleaning machine 10 is placed on the base 20 , the cleaning member 112 is at least partially located in the cleaning tank 21 .

[0036] like Figure 3 As shown, the surface cleaning system 1 further comprises a control component 30, which is connected to the water pump 124, the dirt suction fan 123 and the cleaning member 112. The control component 30 is used to control the working states of the water pump 124, the dirt suction fan 123 and the cleaning member 112.

[0037] When cleaning a clean surface, the control component 30 controls the operation of the dirt suction fan 123 and drives the cleaning member 112 to rotate at the same time. Meanwhile, during the rotation of the cleaning member 112, the control component 30 controls the water pump 124 to work. After the water pump 124 works, the clear water in the clear water tank 122 flows to the cleaning member 112 through the liquid supply pipeline and the water spray nozzle according to a preset flow rate, making the cleaning member 112 in a wet state. Then, the wet cleaning member 112 generates physical friction with the surface to be cleaned during rotation, and the dirt on the surface to be cleaned is removed during the physical friction process. During the process of removing the dirt, dirt will adhere to the cleaning member 112 or the surface to be cleaned. During the rotation of the cleaning member 112, the scraping strip scrapes part of the dirt on the cleaning member 112. During the operation of the dirt suction fan 123, the dirt on the surface to be cleaned and the dirt scraped from the cleaning member 112 are drawn into the dirt suction pipeline through the dirt suction port and enter the sewage bucket 121 through the dirt suction pipeline.

[0038] However, in practice, after the surface cleaning system 1 completes the cleaning of the surface to be cleaned according to the above process, if the user does not clean it in time, the cleaning member 112 with adhered dirt and the sewage bucket 121 for storing dirt will emit an odor after being placed for a long time, greatly reducing the user experience. For this reason, as Figure 2 shown, a cleaning liquid component 22 connected to the control component 30 is provided on the base 20. The cleaning liquid component 22 can supply cleaning liquid to the cleaning tank 21 under the control of the control component 30. Then, to fully exert the bactericidal and deodorizing functions of the cleaning liquid, the cleaning liquid in the cleaning tank 21 and the clear water are mixed evenly by means of the cleaning member 112. After mixing, the cleaning member 112 and / or the sewage bucket 121 are sterilized and deodorized. Among them, the cleaning liquid is a cleaning agent, a deodorant, or a mixed solvent with both cleaning and deodorizing functions for cleaning the cleaning member 112. However, in practice, after the cleaning of the surface to be cleaned is completed, dirt usually adheres to the cleaning member 112. When the cleaning member 112 is located in the cleaning tank 21, part of the dirt will fall into the cleaning tank 21, and part of the dirt remains on the cleaning member 112. The presence of the above dirt will prevent the cleaning liquid from being fully mixed with the clear water, affecting the mixing effect of the liquid mixture, and further affecting the bactericidal effect on the cleaning member 112 and / or the sewage bucket 121. In addition, when there is dirt with strong adhesion on the cleaning member 112, it will prevent the mixed liquid from contacting the cleaning member 112, affecting the bactericidal effect on the cleaning member 112. To solve the above problems, the present application provides a self-cleaning method for the surface cleaning system 1. This method is performed by the control component 30. The working principle of the self-cleaning method of the surface cleaning system 1 in the present application will be described in detail below:

[0039] Please refer to Figure 4 , which is a schematic flow chart of the self-cleaning method of the surface cleaning system 1 shown in the present application. Please refer to Figure 5, which is a schematic structural diagram of the cleaning liquid assembly 22 shown in the present application. Please refer to Figure 6 , which is a schematic diagram of the flow of the cleaning liquid shown in the present application. Please refer to Figure 7 , which is a partial cross-sectional view of the surface cleaning system 1 shown in the present application. As Figure 4 shown, in this embodiment, the self-cleaning method of the surface cleaning system 1 includes a pretreatment step S1 and a liquid mixing step S2. The principles of the pretreatment step S1 and the liquid mixing step S2 will be explained in detail below.

[0040] Pretreatment step S1: Clean the cleaning member 112 to prevent dirt from interfering with the liquid mixing effect.

[0041] In this embodiment, the control component 30 will execute the pretreatment step S1 before liquid mixing. In the pretreatment step S1, the cleaning member 112 and the cleaning tank 21 will be pretreated to remove the dirt in the cleaning member 112 and the cleaning tank 21, thereby reducing the interference of dirt on the liquid mixing process when mixing the cleaning liquid and clean water, improving the liquid mixing effect, and further improving the sterilization effect on the cleaning member 112 and / or the sewage bucket 121. Further, by removing the dirt on the cleaning member 112, the cleaning liquid can fully and evenly contact the cleaning member 112, ensuring the sterilization effect on the cleaning member 112.

[0042] In this embodiment, in the pretreatment step S1, the control component 30 controls the cooperation of the water supply component, the sewage suction component, and the cleaning member 112 to realize the preliminary cleaning of the cleaning member 112 and the cleaning tank 21, and preliminarily clean the large particle dirt in the cleaning member 112 and the cleaning tank 21 to avoid large stains remaining on the surface and interfering with the liquid flow path of the liquid mixing step S2. Specifically, in the pretreatment step S1, the control component 30 starts the water supply component, the sewage suction component, and the cleaning member 112 at the same time; or, first starts the water supply component to soak the cleaning member 112, and then starts the sewage suction component and the cleaning member 112 after the water supply component runs for the first preset duration. The sewage suction component generates a suction force to cooperate with the rotation of the cleaning member 112 to clean the dirt in the cleaning member 112 and the cleaning tank 21. During the cleaning process, the dirt adhering to the cleaning member 112 is sucked through the sewage suction port 125 and the sewage suction pipe into the sewage bucket 121 to remove the dirt adhering to the cleaning member 112; at the same time, during the operation of the cleaning member 112, it will also contact the surface of the cleaning tank 21 to clean the surface of the cleaning tank 21. After cleaning, the cleaning member 112 cooperates with the sewage suction fan 123 to suck the dirt on the cleaning tank 21 into the sewage bucket 121, thereby removing the dirt in the cleaning tank 21.

[0043] Of course, it can be understood that after the water supply component stops operating in the pre-treatment step S1, the control component 30 can continue to control the sewage suction component and the cleaning member 112 to operate for a period of time. After the water supply component stops operating, there may be residual dirt on the cleaning tank 21 and the cleaning member 112. By making the cleaning member 112 and the sewage suction component operate with a time delay for a period of time, the residual dirt in the cleaning member 112 and the cleaning tank 21 is removed.

[0044] It can be seen that in this embodiment, in the pre-treatment step S1, the dirt on the cleaning tank 21 and the cleaning member 112 can be removed, the influence of the dirt on the cleaning tank 21 and the cleaning member 112 on the mixed liquid is reduced, and the mixing effect of the mixed liquid is improved.

[0045] Mixing step S2: Control the water supply component to supply clean water into the cleaning tank 21, control the cleaning liquid component 22 to supply cleaning liquid into the cleaning tank 21, and control the cleaning member 112 to rotate to mix the cleaning liquid and the clean water.

[0046] When performing the mixing step S2, the control component 30 will control the water supply component to supply clean water into the cleaning tank 21. The specific water supply method is that the control component 30 controls the water pump 124 to work. After the water pump 124 works, the clean water in the clean water tank 122 flows into the cleaning tank 21 through the liquid supply pipeline and the spray nozzle at a certain flow rate, or the clean water flows to the cleaning tank 21 through the cleaning member 112 after flowing out of the spray nozzle. In the mixing step S2, the control component 30 will also control the cleaning liquid component 22 to supply cleaning liquid into the cleaning tank 21. The specific method of supplying cleaning liquid is as Figure 5 shown. The cleaning liquid component 22 includes a liquid storage unit 221 and a liquid outlet nozzle 410. The liquid storage unit 221 is connected to the liquid outlet nozzle 410 for storing the cleaning liquid. The liquid outlet nozzle 410 is provided with a liquid outlet 2222, and the liquid outlet 2222 is located in the cleaning tank 21. Under the control of the control component 30, the cleaning liquid in the liquid storage unit 221 flows into the cleaning tank 21 through the liquid outlet 2222 at a certain flow rate to clean and deodorize the cleaning member 112.

[0047] During the process of supplying clean water and cleaning liquid, or after the supply of clean water and cleaning liquid is completed, the control component 30 can control the cleaning member 112 to rotate. During the rotation of the cleaning member 112, the cleaning liquid and clean water are mixed. Since the cleaning liquid has functions such as deodorization and sterilization, during the process of the cleaning member 112 mixing the cleaning liquid and clean water, the mixed cleaning liquid continuously contacts the cleaning member 112, uniformly wets the cleaning member 112, realizes the sterilization and deodorization of the cleaning member 112, so that the cleaning member 112 can be in a clean state covered by the mixed cleaning liquid of the cleaning liquid and clean water, alleviating the situation of the cleaning member 112 emitting an odor. Optionally, when a cleaning liquid with an aromatic function is selected, the cleaning member 112 can also present an aromatic state, improving the user experience; at the same time, during the rotation of the cleaning member 112, the cleaning liquid and clean water are gradually mixed evenly, that is, the cleaning member 112 stirs the liquid in the cleaning tank 21 during rotation, forming a fully mixed cleaning liquid. The mixed cleaning liquid uniformly wets the cleaning member 112 and penetrates into the cleaning member 112 with the rotation of the cleaning member 112 to uniformly soak the cleaning member 112, thereby realizing comprehensive sterilization and deodorization of the cleaning member 112 and reducing the occurrence of local omissions.

[0048] It should be noted that clean water and the cleaning liquid can be injected into the cleaning tank 21 simultaneously, and the cleaning liquid and clean water can be fully mixed by the convection between the liquids; or, clean water is first injected into the cleaning tank 21 and then the cleaning liquid is injected, so that the cleaning liquid injected into the cleaning tank 21 directly mixes with the clean water, reducing the adhesion of the cleaning liquid to the cleaning member 112 and / or the cleaning tank 21 and improving the liquid mixing effect; or, the cleaning liquid is first injected into the cleaning tank 21 and then clean water is injected, and the flowing clean water is used to flush and mix the cleaning liquid that has been injected into the cleaning tank 21. Combining different surface cleaning systems 1, the structure of the cleaning tank 21 can be specifically designed.

[0049] Such as Figure 5 And Figure 6As shown, the cleaning tank 21 includes a first side wall 212, a second side wall 211, a bottom wall 213, and a fourth side wall 214 that can surround the cleaning member 112. The cleaning liquid assembly 22 includes a liquid outlet nozzle 410 that at least partially protrudes from the bottom wall 213 of the cleaning tank 21, and at least one liquid outlet 2222 communicating with the cleaning tank 21 is provided on the liquid outlet nozzle 410. The liquid outlet 2222 of the cleaning liquid faces the side wall of the cleaning tank 21. If the liquid outlet 2222 is arranged with the opening facing upward, since the cleaning liquid has a greater viscosity than water, when the cleaning liquid flows out from the upwardly arranged liquid outlet 2222, it accumulates in the liquid outlet 2222 and slowly flows as the amount of the cleaning liquid discharged gradually increases. Then, during the process of discharging the cleaning liquid from the liquid outlet 2222, the cleaning liquid is likely to adhere to the periphery of the liquid outlet 2222, partially or completely blocking the liquid outlet 2222, thereby making it impossible for the liquid outlet 2222 to discharge the cleaning liquid smoothly and continuously, or even causing the liquid outlet 2222 to be completely unable to discharge the cleaning liquid, and further resulting in the concentration of the cleaning liquid in the cleaning tank 21 not meeting the requirements and affecting the sterilization effect on the cleaning member 112. In the present application, by making the liquid outlet 2222 of the cleaning liquid face the side wall of the cleaning tank 21, the situation of the cleaning liquid blocking the liquid outlet 2222 is alleviated, so that the liquid outlet 2222 can discharge the cleaning liquid smoothly and continuously, enabling the concentration of the cleaning liquid in the cleaning tank 21 to meet the requirements and ensuring the cleaning and sterilization effects on the cleaning member 112.

[0050] Preferably, as Figure 5 and Figure 6As shown, a liquid outlet 2222 is provided on the liquid outlet nozzle 410, and the liquid outlet 2222 faces the first side wall 212 or the second side wall 211. A roller brush cavity 111 for accommodating the cleaning member 112 is provided on the floor brush assembly 110. The cleaning member 112, the scraping strip 113, and the water spraying plate 114 can be arranged in the roller brush cavity 111, and the water spraying plate 114 is arranged above the scraping strip 113. When the water supply assembly supplies clean water, the clean water is sprayed out through the water spraying openings on the water spraying plate 114. If the cleaning member 112 does not rotate at this time, the clean water accumulates and flows for a period of time above the scraping strip 113 and then drips along both sides of the scraping strip 113 onto the cleaning tank 21. If the cleaning member 112 rotates at this time, at least part of the clean water provided by the water supply assembly falls into the cleaning tank 21 along with the rotating cleaning member 112 under the action of the rotating cleaning member 112. As a preferred solution, to ensure the mixing effect, there is at least an interval during which the cleaning member 112 does not rotate during the clean water supply stage. Therefore, when the water supply assembly supplies clean water into the cleaning tank 21, part of the clean water sprayed out from the water spraying openings on the water spraying plate 114 flows into the cleaning tank 21 through the cleaning member 112, and part of the clean water continues to flow on the upper surface of the scraping strip 113 and then drips along both sides of the scraping strip 113 onto the cleaning tank 21. The liquid flow entering the cleaning tank 21 converges from both ends of the cleaning tank 21 to the middle under the action of the liquid flow dripping from the scraping strip 113 subsequently. Since the liquid outlet 2222 of the cleaning liquid in the present application faces the first side wall 212 or the second side wall 211 on both sides of the cleaning tank 21, the liquid outlet 2222 can be washed during the process of the clean water converging to the middle of the cleaning tank 21, so as to clean the liquid outlet 2222, and the dirt attached around the liquid outlet 2222 can be removed, enabling the liquid outlet 2222 to discharge the cleaning liquid smoothly and continuously.

[0051] Those skilled in the art can think that the flow directions of the liquid at the liquid outlet 2222 facing the first side wall 212 and the second side wall 211 of the cleaning tank 21 are substantially the same. To further optimize the mixing effect, in this embodiment, the structure of the cleaning tank 21 is further described by taking the liquid outlet 2222 facing the first side wall 212 of the cleaning tank 21 as an example. As Figure 5 and Figure 6As shown, in the present application, the liquid outlet 2222 of the cleaning liquid is located in the cleaning tank 21 and is far from the central axis L of the base 20. Specifically, the liquid outlet 2222 is far from the central axis L of the base 20. For example, the distance between the liquid outlet 2222 and the first side wall 212 is L1, and the distance between the liquid outlet 2222 and the second side wall 211 is L2; L1 and L2 are not equal, and L1 is less than L2. When the water supply component supplies clean water into the cleaning tank 21, part of the clean water continues to flow on the upper surface of the squeegee 113 and then drips onto the cleaning tank 21 along both sides of the squeegee 113. The liquid flow entering the cleaning tank 21 converges from both ends of the cleaning tank 21 to the middle under the action of the liquid flow dripping from the squeegee 113 subsequently. Then, the liquid outlet 2222 set far from the central axis L of the base 20 makes the flowing cleaning liquid at least opposite to the flowing direction of part of the clean water. That is, the cleaning liquid discharged from the liquid outlet 2222 flows into the cleaning tank 21 and then flows towards the side wall of the cleaning tank 21 according to Figure 6 shown, and during the flow of the cleaning liquid, it convects with the clean water converging towards the middle, and the occurrence of convection further improves the mixing effect of the cleaning liquid and the clean water. Further, if the viscosity of the cleaning liquid is very strong and the fluidity is poor, when the liquid outlet 2222 is far from the central axis L, the clean water can scour and dissolve the cleaning liquid during the process of converging towards the middle, which can also improve the mixing effect of the cleaning liquid and the clean water. In addition, as Figure 7 shown, the dirt suction port 125 is generally close to the central axis L of the base 20. In the present application, the liquid outlet 2222 is far from the central axis L of the base 20, so that the liquid outlet 2222 is far from the dirt suction port 125. Because in the pretreatment stage S1, the dirt on the cleaning tank 21 and the cleaning member 112 will be absorbed into the sewage bucket 121 through the dirt suction port 125. In the present application, by making the liquid outlet 2222 far from the dirt suction port 125, it is prevented that the dirt adheres and blocks at the liquid outlet 2222 during the process of absorbing the dirt, so that the liquid outlet 2222 can discharge the cleaning liquid smoothly and continuously. On the other hand, the liquid outlet 2222 is set far from the central axis L, so that a smaller mixing space is formed between the liquid outlet 2222 and the first side wall 212 or the second side wall 211 it approaches. The clean water and the cleaning liquid are mixed in the mixing space and flow towards the direction close to the central axis L as the clean water or the cleaning liquid continues to increase, which promotes the flow of the cleaning liquid and the clean water in the transverse axis direction of the cleaning tank 21.

[0052] Optionally, multiple liquid outlets 2222 can be provided in the cleaning tank 21. For example, there are at least two liquid outlets 2222 respectively facing the first side wall 212 and the second side wall 211. The liquid outlets 2222 supply the cleaning liquid substantially along the axis of the cleaning member 112, and try to make it evenly distributed in the cleaning tank 21 during the cleaning liquid discharging stage. Compared with the way of discharging the cleaning liquid only along one side, it is easier to mix the cleaning liquid and the clean water.

[0053] As Figure 7As shown, the liquid outlet 2222 of the cleaning liquid is located on the front side of the front edge of the squeegee 113. As an alternative implementation, the distance between the liquid outlet 2222 of the cleaning liquid and the front edge of the squeegee 113 is L3, where 0 < L3 < 25 mm. When the bottom of the cleaning tank 21 has an inclination angle, under the action of the above inclination angle, if the water supply assembly supplies clean water into the cleaning tank 21, the clean water accumulated on the squeegee 113 flows into the cleaning tank 21 and gradually flows from the rear side to the front side of the cleaning tank 21. Preferably, the cleaning tank 21 is a groove with a certain arc or inclination angle that matches the shape of the cleaning member 112; or, the cleaning tank 21 is a groove with a flat bottom, and the projection of the squeegee 113 in the vertical direction is located in the cleaning tank 21 and on the rear side of the cleaning tank 21. If clean water is provided first and then the cleaning liquid is provided during the liquid mixing stage, or clean water and the cleaning liquid are provided simultaneously during the liquid mixing stage, the liquid outlet 2222 can be flushed and cleaned during the flow of the clean water to prevent dirt from blocking the liquid outlet 2222 and affecting the outflow of the cleaning liquid. If the cleaning liquid is provided first and then clean water flows out during the liquid mixing stage, the clean water flowing from the back to the front can also flush and dissolve the cleaning liquid in the cleaning tank 21, and drive the cleaning liquid to move towards the front side area of the cleaning tank 21. During the movement process, the cleaning liquid is evenly distributed in the cleaning tank 21, and the mixing effect with the clean water is better.

[0054] Embodiment Two:

[0055] Based on Embodiment One, this embodiment further describes the self-cleaning method of the surface cleaning system 1. This embodiment provides a self-cleaning method for the surface cleaning system 1, which includes a pretreatment step S1, a liquid mixing step S2, a cleaning step S3, and a cleaning and suction step S4. The working principle of the self-cleaning method of the surface cleaning system 1 in this application is explained in detail below:

[0056] Pretreatment step S1: Pretreat the cleaning member 112 and the cleaning tank 21 to remove the dirt on the cleaning tank 21 and the cleaning member 112, so as to reduce the influence of the dirt on the liquid mixing process.

[0057] Liquid mixing step S2: Control the water supply assembly to supply clean water into the cleaning tank 21, control the cleaning liquid assembly 22 to supply the cleaning liquid into the cleaning tank 21, and control the cleaning member 112 to rotate to mix the cleaning liquid and the clean water.

[0058] In this embodiment, in the liquid mixing step S2, the control component 30 first controls the water supply component to supply clean water into the cleaning tank 21, and then controls the cleaning liquid component 22 to supply the cleaning liquid into the cleaning tank 21. Specifically, the control component 30 first controls the water supply component to operate to supply clean water into the cleaning tank 21, and after the water supply component stops operating or operates for a period of time, it then controls the cleaning liquid component 22 to operate to supply the cleaning liquid into the cleaning tank 21. On the one hand, to enable the cleaning liquid to play its role well, it is necessary to control the mixing of the cleaning liquid and clean water in a certain proportion. Injecting clean water first can make it more convenient to determine the injection volume of the cleaning liquid. On the other hand, the cleaning liquid is usually more viscous than clean water. When injecting the cleaning liquid first, the cleaning liquid is likely to adhere to the cleaning part 112 and / or the inner wall of the cleaning tank 21, affecting the mixing effect of the clean water and the cleaning liquid. In this embodiment, injecting clean water first and then injecting the cleaning liquid enables the relatively viscous cleaning liquid to be fully dissolved in the clean water, improving the liquid mixing effect. In addition, because the cleaning liquid is relatively viscous, injecting clean water first and then injecting the cleaning liquid can also prevent the cleaning liquid from blocking the liquid outlet 2222, making the liquid outlet 2222 at least partially wrapped by clean water discharge more smoothly.

[0059] In this step, during the process of supplying clean water and the cleaning liquid, or after the clean water and the cleaning liquid are supplied, the control component 30 can control the cleaning part 112 to rotate. During the rotation of the cleaning part 112, the cleaning liquid and clean water are mixed, and the cleaning part 112 is sterilized and deodorized during the mixing process and after the liquid is fully mixed. Optionally, the control component 30 can control the cleaning part 112 to rotate in a forward and reverse alternating manner. Forward and reverse alternating rotation means that in the liquid mixing step S2, the control component 30 controls the cleaning part 112 to rotate, and the rotation direction of the cleaning part 112 includes both forward rotation and reverse rotation; specifically, it can first control the cleaning part 112 to rotate forward and then control the cleaning part 112 to rotate backward, and then control the cleaning part 112 to rotate forward and backward again, so as to continuously control the rotation of the cleaning part 112 in this cycle; or, it can first control the cleaning part 112 to rotate backward and then control the cleaning part 112 to rotate forward, and then control the cleaning part 112 to rotate backward and forward again, so as to continuously control the rotation of the cleaning part 112 in this cycle. As Figure 7 shown, when the cleaning machine 10 is placed on the base 20, the cleaning part 112 is located in the cleaning tank 21. When the cleaning part 112 rotates backward, it rotates in the T1 direction shown in Figure 7 . If the cleaning part 112 only rotates backward in the liquid mixing step S2, it is easy to splash the liquid in the cleaning tank 21 outside; when the cleaning part 112 rotates forward, it rotates in accordance with Figure 7Rotating in the T2 direction shown in the figure, if the cleaning member 112 only rotates forward in the above-mentioned mixing step S2, it is easy to hinder the flow of the cleaning liquid towards the center of the cleaning tank 21, affecting the mixing effect of the cleaning liquid and the clear water. In this embodiment, the cleaning member 112 is controlled to rotate forward and backward alternately, so that during the process of the cleaning member 112 rotating forward and backward alternately, the cleaning liquid can oscillate back and forth in the cleaning tank 21 at a certain frequency, ensuring the mixing effect of the cleaning liquid and the clear water, and to a certain extent alleviating the splashing of the liquid in the cleaning tank 21 to the outside.

[0060] Furthermore, when controlling the cleaning member 112 to rotate forward and backward alternately, the cleaning member 112 can be controlled to rotate backward first. As Figure 7 shown, the liquid outlet 2222 of the cleaning liquid is at the rear side of the cleaning tank 21. When the cleaning liquid is supplied through the liquid outlet 2222, the cleaning liquid converges at the rear side of the cleaning tank 21. When the cleaning member 112 is first controlled to rotate reversely, the cleaning member 112 rotates in the T1 direction, which can drive the cleaning liquid to move towards the front side area of the cleaning tank 21. During the movement, the cleaning liquid is evenly distributed in the cleaning tank 21, and the mixing effect with the clear water is better. At the same time, since the liquid outlet 2222 of the cleaning liquid is located at the rear side of the cleaning tank 21, when the cleaning member 112 is first controlled to rotate forward, it is easy to drive the cleaning liquid to a place closer to the sewage suction port 125, resulting in the cleaning liquid and the clear water being more difficult to be mixed evenly. In this embodiment, first controlling the cleaning member 112 to rotate backward can effectively solve the above problems.

[0061] Furthermore, the rotation speed V when the cleaning member 112 rotates reversely 1 can be less than the rotation speed V when the cleaning member 112 rotates forward 2 . Since the cleaning member 112 can scour the sewage suction port 125 when rotating forward, when the rotation speed V of the cleaning member 112 rotating forward 1 is faster, the scouring force on the sewage suction port 125 is stronger and the cleaning effect is also stronger. When rotating reversely, controlling the cleaning member 112 to rotate at a low speed can reduce the splashing of the water in the cleaning tank 21 to the outside. At the same time, the bristles on the cleaning member 112 will be lifted up when rotating reversely. When the cleaning member 112 rotates at a low speed, it can slowly and evenly wet the cleaning member 112, improving the bactericidal effect on the cleaning member 112. In addition, the cleaning member 112 is driven to rotate by a driving motor. When the driving motor rotates forward, it drives the cleaning member 112 to rotate forward. When the driving motor rotates backward, it drives the cleaning member 112 to rotate backward. When rotating reversely, controlling the cleaning member 112 to rotate at a low speed can also effectively reduce the reverse current of the driving motor and protect the driving motor.

[0062] Further, in the liquid mixing step S2, the control component 30 can control the sewage suction component to close. After the sewage suction component closes, the sewage suction fan 123 stops operating. When the sewage suction fan 123 stops operating, the cleaning liquid will not be absorbed into the sewage bucket 121, so that more cleaning liquid can be retained in the cleaning tank 21, ensuring the sterilization effect on the cleaning part 112.

[0063] After the liquid mixing step S2 is completed, the self-cleaning method of the surface cleaning device further includes a cleaning step S3 of cleaning the cleaning part 112 and a sewage suction cleaning step S4.

[0064] Cleaning step S3: Control the cleaning part 112 to rotate intermittently, and the cleaning part 112 is stationary for a preset duration between two adjacent rotations.

[0065] After entering the cleaning step S3, it can be stationary for a preset duration T3 first, and then control the cleaning part 112 to rotate forward or backward n1 circles, where n1 is a non-integer or an integer; the control component 30 counts the number of rotations of the cleaning part 112 in the cleaning step S3; after each rotation of the cleaning part 112, it is judged whether the total number of rotations reaches n2 circles. When the total number of rotations of the cleaning part 112 reaches n2 circles, the cleaning step S3 is stopped; otherwise, the above steps of stationary and rotating the cleaning part 112 are repeated.

[0066] After experiencing the liquid mixing step S2, the cleaning liquid and the clear water are mixed evenly. In the cleaning step S3, the cleaning part 112 is controlled to rotate intermittently and is stationary between two adjacent rotations, so that the mixed liquid can fully and evenly infiltrate the cleaning part 112, realizing uniform sterilization of the cleaning part 112 and inhibiting the odor caused by bacterial growth on the cleaning part 112. At the same time, in the pretreatment step S1, only the large particle dirt adhered to the cleaning part 112 is removed. In the cleaning step S3, controlling the cleaning part 112 to rotate intermittently can also enable the scraping strip 113 to scrape and clean the cleaning part 112, removing the fine stains adhered to the cleaning part 112 and improving the cleanliness of the cleaning part 112.

[0067] Sewage suction cleaning step S4: Control the sewage suction fan 123 to operate and control the cleaning part 112 to operate, so as to absorb the liquid on the cleaning tank 21 and the cleaning part 112 into the sewage bucket 121 through the sewage suction port 125 and the sewage suction pipeline.

[0068] After the liquid mixing step S2 and the cleaning step S3, the liquid on the cleaning tank 21 and the cleaning member 112 becomes turbid. Therefore, when the control component 30 executes the cleaning suction step S4, it is necessary to timely absorb the liquid in the cleaning member 112 and the cleaning tank 21 into the sewage bucket 121 to improve the cleanliness of the cleaning member 112 and the cleaning tank 21. Specifically, when the control component 30 executes the cleaning suction step S4, it can control the operation of the sewage suction fan 123 and the cleaning member 112. After operation, the sewage suction fan 123 and the cleaning member 112 cooperate to absorb the liquid on the cleaning member 112 and the cleaning tank 21 into the sewage bucket 121 through the sewage suction port 125 and the sewage suction pipe. Among them, in the pretreatment step S1, the dirt on the cleaning member 112 and the cleaning tank 21 is absorbed into the sewage bucket 121 through the sewage suction pipe. During the dirt absorption process, the sewage suction pipe and the sewage bucket 121 will adhere to dirt, and it is easy to stink due to bacterial growth after long-term placement. Since the liquid on the cleaning tank 21 and the cleaning member 112 contains cleaning liquid, during the absorption of the above liquid, the liquid contacts the sewage suction pipe, performing bactericidal and deodorizing treatment on the sewage suction pipe, alleviating the stinking situation of the sewage suction pipe; at the same time, when the liquid is sucked into the sewage bucket 121, the cleaning liquid contained in the liquid can also perform bactericidal and deodorizing treatment on the sewage bucket 121, alleviating the stinking situation of the sewage bucket 121.

[0069] Of course, it can be understood that in the cleaning suction step S4, the sewage suction fan 123 can operate at a power P3, where P3 can be greater than the minimum operating power of the sewage suction fan 123 and less than twice the minimum operating power of the sewage suction fan 123; in this way, the noise of the sewage suction fan 123 during operation is reduced, and at the same time, the liquid on the cleaning tank 21 can flow through all positions of the sewage suction pipe and then enter the sewage bucket 121, realizing full bactericidal treatment of the sewage suction pipe.

[0070] Of course, it can be understood that in the cleaning suction step S4, after the cleaning member 112 stops operating, the sewage suction fan 123 can be delayed in closing. By delaying the closing of the sewage suction fan 123, the residual liquid in the sewage suction pipe is absorbed, alleviating the situation where the residual liquid in the sewage suction pipe flows back to the cleaning tank 21. Among them, the sewage suction fan 123 can first operate at a power P3, and when the sewage suction fan 123 is delayed in closing, it can operate at a power P4 greater than the power P3.

[0071] Further, the interference amount between the scraping strip 113 and the cleaning member 112 in the pretreatment step S1 is J1, the interference amount between the scraping strip 113 and the cleaning member 112 in the liquid mixing step S2 is J2, and the interference amount between the scraping strip 113 and the cleaning member 112 in the cleaning step S3 is J3; it should be ensured that J2 < J1 ≤ J3; by the above settings, the interference amount J2 between the scraping strip 113 and the cleaning member 112 in the liquid mixing step S2 is reduced, so that the cleaning liquid and the clear water can fully infiltrate the cleaning member 112, ensuring the sterilization effect on the cleaning member 112; because the cleaning member 112 in the pretreatment step S1 is relatively dry and contains less water, if J1 is relatively large, it is easy to increase the load current of the drive motor driving the cleaning member 112. Setting J1 smaller can reduce the load current of the drive motor driving the cleaning member 112 and protect the drive motor; in addition, in the pretreatment step S1, only relatively large solid residues are cleaned, and it is not necessary to deeply clean the inside of the cleaning member 112, so a smaller J1 can meet the cleaning requirements; because the cleaning member 112 contains more water in the cleaning step S3, even if J3 is relatively large, it will not cause the load current of the drive motor driving the cleaning member 112 to be too large; and in the cleaning step S3, it is necessary to fully clean the cleaning member 112, so J3 needs to be set relatively large, thereby fully ensuring the scraping and cleaning effect of the scraping strip 113 on the cleaning member 112.

[0072] Embodiment 3:

[0073] On the basis of Embodiment 1, this embodiment further describes the self-cleaning method of the surface cleaning system 1.

[0074] Optionally, in this embodiment, the rotation of the cleaning member 112 in the liquid mixing step S2 further includes the intermittent forward rotation of the cleaning member 112. The forward rotation of the cleaning member 112 drives the liquid flow in the cleaning tank 21 to move from the front side of the cleaning tank 21 to the rear side of the cleaning tank 21. The sewage suction port 125 is located at the rear side of the cleaning member 112, that is, the rear side of the cleaning tank 21. The liquid flowing backward enters at least part of the sewage suction port 125 with the rotation of the cleaning member 112, flushes the sewage suction port 125 and then flows out. The cleaning member 112 rotates forward intermittently. On the one hand, the intermittently forward rotating cleaning member 112 can make the liquid flow in the cleaning tank 21 with the movement of the cleaning member 112 during the rotation process to promote liquid mixing. When the cleaning member 112 stops rotating, the liquid continues to flow under the action of inertia, giving the liquid sufficient mixing time. On the other hand, the intermittently forward rotating cleaning member 112 generates a liquid flow that intermittently flushes the sewage suction port 125. The liquid flow forms a continuous impact liquid flow that flushes the sewage suction port 125 with the rotation of the cleaning member 112, which can intermittently flush the sewage suction port 125 and remove the dirt attached to the sewage suction port 125.

[0075] Embodiment 4:

[0076] This embodiment provides a self - cleaning method for a surface cleaning system 1, and this method includes a pretreatment step S1, a liquid mixing step S2, a cleaning step S3, and a cleaning and suction step S4.

[0077] Pretreatment step S1: The control component 30 can control the operation of the water supply component, the sewage suction fan 123, and the cleaning member 112 to remove the dirt on the cleaning tank 21 and the cleaning member 112, reducing the influence of the dirt on the liquid mixing process.

[0078] Liquid mixing step S2: Control the water supply component to supply clean water into the cleaning tank 21, control the cleaning liquid component 22 to supply cleaning liquid into the cleaning tank 21, and control the cleaning member 112 to rotate to mix the cleaning liquid and the clean water.

[0079] Among them, there is at least a pulse liquid mixing stage in the liquid mixing step S2. In the pulse liquid mixing stage, the control component 30 controls the sewage suction component to operate at a power lower than that in the pretreatment step S1. Among them, assuming that the sewage suction component operates at a power of P1 in the pretreatment step S1, then in the pulse liquid mixing stage, the control component 30 can control the sewage suction component to operate at a power of P2, where P2 is less than P1.

[0080] In this embodiment, during the execution of the liquid mixing step S2 by the control component 30, the pulse liquid mixing stage can be simultaneously executed. In the pulse liquid mixing stage, the control component 30 controls the operation of the sewage suction fan 123. Among them, the sewage suction fan 123 can be controlled to operate at a constant low power, or the sewage suction fan 123 can be controlled to operate with alternating high and low powers. After the sewage suction fan 123 operates, the clean water and the cleaning liquid on the cleaning tank 21 are absorbed into the sewage suction pipe in the form of a liquid flow and move back and forth in the sewage suction pipe. After moving back and forth for a period of time, the control component 30 stops the operation of the sewage suction fan 123. After the sewage suction fan 123 stops operating, the pulse liquid mixing stage is completed, and the liquid flow falls back into the cleaning tank 21. Among them, when the liquid flow moves in the sewage suction pipe, it helps the cleaning liquid and the clean water to be mixed evenly, improving the liquid mixing effect of the cleaning liquid and the clean water; at the same time, since dirt will also adhere to the sewage suction pipe, when the liquid flow moves back and forth in the sewage suction pipe, it can also clean and sterilize the sewage suction pipe, improving the cleanliness of the sewage suction pipe and alleviating the odor of the sewage suction pipe, enhancing the user experience.

[0081] Cleaning step S3: Control the cleaning member 112 to rotate intermittently, and a preset time duration is set for standing still between two adjacent rotations of the cleaning member 112.

[0082] Cleaning and suction step S4: Control the operation of the sewage suction fan 123 and the operation of the cleaning member 112 to absorb the liquid on the cleaning tank 21 and the cleaning member 112 into the sewage bucket 121 through the sewage suction port 125 and the sewage suction pipe.

[0083] Embodiment Five:

[0084] Based on the above embodiments, the present embodiment provides a triggering method for a self-cleaning, sterilizing, and deodorizing solution and a method for controlling the mixing ratio of the liquid mixture.

[0085] Optionally, an in-place detection unit may be provided on the surface cleaning system 1. When the cleaning machine 10 finishes the cleaning work and is placed on the base 20, the control component 30 can detect the placement duration of the sewage bucket 121 on the body component 120 through the in-place detection unit, and / or the control component 30 can detect whether there is sewage in the sewage bucket 121. When the placement duration reaches the set value, and / or when there is sewage in the sewage bucket 121, the self-cleaning method of the above surface cleaning system 1 is executed to sterilize the sewage bucket 121, the cleaning part 112, and the sewage suction pipeline. Among them, when executing the self-cleaning method of the above surface cleaning system 1, the pretreatment step S1, the liquid mixing step S2, the cleaning step S3, and the cleaning and suction step S4 can be executed in sequence; or, when executing the self-cleaning method of the above surface cleaning system 1, the liquid mixing step S2, the cleaning step S3, and the cleaning and suction step S4 can be executed in sequence; Detection units such as a water level electrode, a weight sensor, and an infrared sensor can be installed on the sewage bucket 121, and the control component 30 can detect whether there is sewage in the sewage bucket 121 through the above detection units.

[0086] Alternatively, the mixing ratio of the liquid mixing step S1 can be controlled according to the in-place duration of the sewage bucket 121 detected by the in-place detection unit and / or the volume of sewage in the sewage bucket 121. Specifically, an in-place detection unit may be provided on the surface cleaning system 1. When executing the liquid mixing step S2, the control component 30 can adjust the ratio of clean water and cleaning liquid according to the placement duration of the sewage bucket 121 on the body component 120 before executing the self-cleaning method of the surface cleaning system 1; if the placement duration of the sewage bucket 121 on the body component 120 is longer, and / or the more sewage there is in the sewage bucket 121, the more bacteria will breed. At this time, to ensure the sterilization effect, the ratio of the cleaning liquid to clean water needs to be increased; if the placement duration of the sewage bucket 121 on the body component 120 is shorter, and / or the less sewage there is in the sewage bucket 121, the less bacteria will breed. At this time, the ratio of the cleaning liquid to clean water can be reduced.

[0087] Optionally, a dirt detection unit may be provided on the surface cleaning system 1 to detect the dirt condition through the dirt detection unit and adjust the ratio of clean water and cleaning liquid in the liquid mixing step S2 according to the detection result. Specifically, when there is more dirt, the ratio of the cleaning liquid to clean water may be increased; when there is less dirt, the ratio of the cleaning liquid to clean water may be decreased, thereby improving the sterilization and deodorization effects. Exemplarily, the minimum volume ratio of the cleaning liquid to water is 1:300; the maximum volume ratio of the cleaning liquid to water is 1:1. Preferably, the volume ratio of the cleaning liquid to water may be 1:40. The dirt detection unit may detect the dirt condition by means of TDS value detection, resistance value detection, infrared dirt detection, etc. The dirt detection unit may be provided in the sewage bucket 121 to detect the dirt condition in the sewage bucket 121, or the dirt detection unit may be provided in the sewage suction pipeline to detect the dirt condition in the sewage suction pipeline. Alternatively, during the process of the cleaning machine 10 performing the cleaning work on the surface to be cleaned, the dirt detection unit may detect the dirt condition in real time and calculate the average value of the dirt during the entire working cycle, and the dirt condition is reflected by the above average value of the dirt.

Please refer to Figure 8 , which is a connection schematic diagram of the cleaning liquid assembly 22 shown in this application.

[0090] Please refer to Figure 9 , which is Figure 8 a partial enlarged schematic view of the location A in Figure 10 , which is a cross-sectional schematic view of the liquid outlet nozzle 410 shown in the present application. Please refer to Figure 11 , which is a structural schematic view of the liquid outlet nozzle 410 shown in the present application. As Figure 9 shown, the liquid outlet unit 222 includes a liquid outlet nozzle 410 and a fixing bracket 420. The fixing bracket 420 is provided in the base 20. The fixing bracket 420 has a first surface and a second surface arranged opposite to each other. A plurality of fixing grooves 421 are provided on the first surface. A plurality of first fixing protrusions 231 are provided on the inner surface of the housing of the base 20. Each first fixing protrusion 231 extends into the corresponding fixing groove 421; the liquid outlet nozzle 410 and each first fixing protrusion 231 form a through hole, and a fixing element 232 is located in the through hole to fix the fixing bracket 420 on the housing of the base 20.

Exemplarily, the above fixing element 232 can be a screw.

[0091] Of course, it can be understood that, as Figure 9 - Figure 11As shown, a protective cover 411 is provided on the liquid outlet nozzle 410. The protective cover 411 is an arc-shaped drainage plate that connects the liquid outlet nozzle 410 and the cleaning tank 21. The cleaning liquid flowing out of the liquid outlet nozzle 410 is drained by the protective cover 411 and supplied to the side wall of the cleaning tank 21. On the other hand, the protective cover is provided on the liquid outlet nozzle 410 inside the cleaning tank 21, and one end of the protective cover 411 semi-covers the liquid outlet 2222 of the liquid outlet channel 2221. The protective cover 411 is used to protect the liquid outlet 2222 of the liquid outlet channel 2221 and prevent dirt such as fine dust in the cleaning tank 21 from entering the liquid outlet channel 2221 and blocking the liquid outlet channel 2221.

[0092] Of course, it can be understood that one or more cleaning liquid assemblies 22 can be provided on the base 20. Each cleaning liquid assembly 22 includes a liquid storage unit 221, a liquid outlet unit 222, a connecting pipe 223, and a liquid pumping unit 224, and they are all connected and installed on the base 20 in the manner of the above embodiment. When multiple cleaning liquid assemblies 22 are provided, multiple liquid outlet units 222 will be provided on the base 20; the multiple liquid outlet units 222 can be symmetrically distributed along the central plane of the base 20, or the multiple liquid outlet units 222 can be arranged side by side. When the control component 30 executes the liquid mixing step S2, the control component 30 can control one or more liquid pumping units 224 to operate. After the liquid pumping unit 224 operates, one or more cleaning liquid assemblies 22 can provide cleaning liquid into the cleaning tank 21.

[0093] In this embodiment, when multiple cleaning liquid assemblies 22 are provided, the multiple cleaning liquid assemblies 22 can supply cleaning liquid into the cleaning tank 21 simultaneously, improving the liquid supply efficiency of the cleaning liquid.

[0094] Of course, it can be understood that one liquid storage unit 221 can be provided on the base 20, and multiple liquid outlet units 222, multiple connecting pipes 223, and multiple liquid pumping units 224 are provided; the liquid storage unit 221, the multiple liquid outlet units 222, the multiple connecting pipes 223, and the multiple liquid pumping units 224 are installed on the base 20 in the manner of the above embodiment; the liquid outlet units 222 are connected to the connecting pipes 223 in one-to-one correspondence in the manner of the above embodiment, and each connecting pipe 223 is connected to the liquid storage unit 221; the liquid outlet channel 2221 in each liquid outlet unit 222 forms a liquid supply loop with the liquid supply channel 2231 in the connecting pipe 223 corresponding to it, and the liquid storage unit 221 is respectively communicated with each liquid supply loop. Among them, the multiple liquid outlet units 222 can be symmetrically distributed along the central plane of the base 20, or the multiple liquid outlet units 222 can be arranged side by side. In this embodiment, when the control component 30 executes the liquid mixing step S2, the control component 30 can control one or more liquid pumping units 224 to operate. After the liquid pumping unit 224 operates, one or more liquid outlet assemblies can provide cleaning liquid into the cleaning tank 21.

[0095] In this embodiment, multiple liquid outlet units 222 are connected to the same liquid storage unit 221, and the integration degree of the device is high, meeting the manufacturing requirements of miniaturization.

[0096] Of course, it can be understood that after being used for a period of time, dirt may accumulate on the liquid outlet unit 222. The presence of dirt may block the liquid outlet channel 2221. After the liquid outlet channel 2221 is blocked, the cleaning liquid cannot be discharged smoothly, and the sterilization effect on the cleaning part 112 is affected. Therefore, after being used for a period of time, the liquid outlet unit 222 needs to be cleaned to remove the dirt on it so that the liquid outlet channel 2221 can smoothly discharge the cleaning liquid. On the one hand, the liquid outlet unit 222 can be detachably connected to the housing of the base 20. When cleaning the liquid outlet unit 222, the liquid outlet unit 222 can be detached from the housing of the base 20. After detachment, it is cleaned with cleaning liquid or clean water, and after cleaning, the liquid outlet unit 222 is air-dried. After air-drying, the liquid outlet unit 222 is installed on the base 20. On the other hand, please refer to Figure 12 , which is the second structural schematic diagram of the base 20 shown in this application. As Figure 12 shown, in this embodiment, the housing of the base 20 includes a first housing 210 and a second housing 220. The first housing 210 and the second housing 220 are detachably connected, and the liquid outlet unit 222 of the cleaning liquid assembly 22 is connected to the second housing 220. When cleaning the liquid outlet unit 222, the second housing 220 can be detached. After detachment, the liquid outlet unit 222 is cleaned with cleaning liquid or clean water to remove the dirt on it. After cleaning, the liquid outlet unit 222 and the second housing 220 are air-dried. After air-drying, the second housing 220 is installed on the first housing 210.

[0097] Since the structure of the liquid outlet unit 222 is relatively small, in the above embodiment, when cleaning the liquid outlet unit 222, the second housing 220 with the liquid outlet unit 222 attached is detached from the base 20. This method reduces the phenomenon of loss of the liquid outlet unit 222 and facilitates the storage of the liquid outlet unit 222.
