Referring to Figures 3 and 4, Figure 4 is a schematic structural diagram of the base of the cleaning device shown in Figure 3. In this embodiment, the base 10 is provided with an accommodating space 12 penetrating up and down; the water tank 20 is assembled with the accommodating space 12 , and the bottom of the water tank 20 is exposed on the bottom surface of the base 10 .

The accommodating space 12 runs through the base 10, and at least part of the water tank 20 is accommodated in the accommodating space 12 to fully utilize the thickness of the base 10 to accommodate the water tank 20, which can not only reduce the thickness of the cleaning device 100 but also facilitate compactness. In order to facilitate the weight reduction of the cleaning device 100, the cleaning device 100 can operate more flexibly and consume less energy during operation. The base 10 can also carry a larger volume water tank 20 to improve the cleaning endurance of the cleaning device 100. This allows the cleaning device 100 to clean a larger area at one time.

For example, the bottom of the water tank 20 is made of a transparent material, such as transparent glass or transparent plastic, which can transmit light to utilize light for sterilization.

In other embodiments, the accommodating space 12 may not penetrate the base 10 , that is, the accommodating space 12 has a solid bottom, and at least part of the water tank 20 is accommodated in the accommodating space 12 .

Referring to Figures 3, 5 to 8 in conjunction, Figure 5 is a schematic diagram of the exploded structure of the water tank in the cleaning device as shown in Figure 3, Figure 6 is a schematic top view of the clean water bin in the water tank as shown in Figure 5, and Figure 7 is as follows Figure 5 shows a schematic diagram of the shaft side structure of the clean water tank in the water tank. Figure 8 is a schematic diagram of the exploded structure of the filtrate assembly in the water tank as shown in Figure 5.

The water tank 20 includes a clean water tank 22 and a sewage tank 24 that are stacked up and down. The clean water tank 22 and the sewage tank 24 are detachably connected, and the bottom of the sewage tank 24 is exposed on the bottom surface of the base 10 .

Among them, the clean water tank 22 is used to store clean water or a solution with detergent added, and the sewage tank 24 is used to collect and store sewage. At least the sewage tank 24 is made of a transparent material, such as transparent plastic or transparent glass, to facilitate sterilization by light. The technology sterilizes the sewage collected in the sewage bin 24.

By restricting the clean water tank 22 and the sewage tank 24 to be stacked up and down, when the water levels in the clean water tank 22 and the sewage tank 24 change, the center of gravity of the water tank 20 installed on the base 10 only changes in the vertical direction, and does not change in the vertical direction. The horizontal plane is offset, thereby making the center of gravity of the cleaning device 100 more stable, and avoiding the risk of the cleaning device 100 overturning due to the offset of the center of gravity due to changes in liquid levels in each compartment of the water tank 20, and the relative wear of the running wheel on a certain side. When excessive conditions occur, the cleaning device 100 can operate more stably.

The cleaning device 100 also includes an infusion component 70 , which is connected to the clean water tank 22 and used to provide cleaning fluid to the cleaning component 30 .

The cleaning assembly 30 includes a roller brush 32. The roller brush 32 is rotatably mounted on the base 10 for rolling cleaning. For cleaning floors, etc., the infusion assembly 70 is used to provide clean water or cleaning fluid with detergent added to the roller brush 32 so that the roller brush 32 can complete the cleaning operation more efficiently.

As shown in Figures 5 to 7, the water tank 20 is provided with a first airflow port 201 and a second airflow port 202. The first airflow port 201 is disposed toward the cleaning component 30. The fan 50 is connected to the second airflow port 202. The fan 50 is used to generate The airflow carries the dirt on the cleaning assembly 30 into the sewage tank 24 .

Among them, the first air flow port 201 and the second air flow port 202 are both connected to the inner space of the sewage bin 24. The first air flow port 201 and the second air flow port 202 can be provided in the clean water bin 22 and/or the sewage bin 24. The fan 50 pumps When the air flow generated by suction passes through the sewage tank 24, gas-liquid separation is performed in the sewage tank 24. The liquid containing dirt can be collected into the sewage tank 24, and the air flow is discharged through the exhaust port of the fan 50 after passing through the sewage tank 24.

In this embodiment, the first airflow port 201 and the second airflow port 202 are both disposed in the clean water tank 22, so that the airflow channel from the first airflow port 201 to the second airflow port 202 can be relatively located on the upper layer of the sewage tank 24, so as to Avoid the liquid accumulation area located below the sewage tank 24 (the sewage tank 24 forms a liquid accumulation area due to the collection of sewage), thereby effectively reducing the probability that the air flow directly impacts the liquid accumulation area and causes the sewage in the liquid accumulation area to splash, and can The sewage tank 24 can have a relatively larger volume and can collect more sewage containing dirt, and the depth of the sewage tank 24 can be relatively deep, so that even if the cleaning device 100 vibrates during the cruise cleaning operation, it can Because the sewage tank 24 has a large depth and an airflow port 201 and a second airflow port 202 are provided in the clean water tank 22, the risk of the sewage in the sewage tank 24 splashing out can be effectively reduced.

Further, the water tank 20 also includes a filtrate assembly 26, where the filtrate assembly 26 is connected to the clean water tank 24. The air flow channel flowing through the first air flow port 201 and the second air flow port 202 passes through the sewage tank 24 and the filtrate assembly 26, and in the sewage tank 24 To perform gas-liquid separation, the filtrate assembly 26 is used to separate water vapor in the air flow to prevent the air flow from carrying water vapor into the fan 50 .

Specifically, the clean water bin 22 and the sewage bin 24 are stacked up and down. The clean water bin 22 is covered at the entrance of the sewage bin 24. The clean water bin 22 includes a separated water storage area 220 and a flow-through area 222. The water storage area 220 is used for In order to store cleaning liquid such as clean water, the flow area 222 is used to pass air flow, and the second air flow port 202 is connected to the flow area 222 .

The flow-passing area 222 is provided with a filter port 204. The filtrate component 26 is connected to the clean water tank 24 and covers the filter port 204. The airflow passes from the sewage tank 24 through the filtrate component 26, the filter port 204 and the flow-passing area 222 to the second airflow port 202. .

Specifically, the sewage tank 24 has a cavity structure, and the clean water tank 22 includes a diverter plate 221. The diverter plate 221 is disposed between the first airflow port 201 and the filtrate assembly 26 to break up the filtrate flowing through the first airflow port 201 to the filtrate assembly 26. The airflow changes from a relatively concentrated state when entering through the first airflow port 201 to a dispersed state after being dispersed by the splitter plate 221, so as to reduce the impact intensity of the airflow, that is, the impact intensity of the dispersed airflow becomes smaller, so it can Effectively reduce the possibility of sewage splashing caused by airflow impacting the liquid accumulation area. Rate.

The splitter plate 221 can also reduce the flow rate of the air flow, so as to facilitate the gas-liquid separation of the air flow in the sewage bin 24, and the splitter plate 221 is also conducive to gathering and adsorbing sewage contained in the air flow, so that the sewage condenses on it and is collected into the sewage bin. 24 effusion area.

In this embodiment, the splitter plate 221 is arranged in an arc shape and semi-circulates the filtrate assembly 26, so that the airflow into the splitter plate 221 can also go around along the splitter plate 221 to flow to the filtrate assembly 26 in multiple different directions, so that the airflow A vortex is formed in the upper layer of the sewage tank 24 to facilitate gas-liquid separation.

The manifold plate 221 is arranged symmetrically, and the distance between the lower edge of the manifold plate 221 and the bottom wall of the sewage tank 24 gradually decreases from the symmetrical center to the edge, so that the airflow can be dispersed along the manifold plate 221 along its various directions. The lower edge flows toward the filtrate assembly 26.

The first airflow port 201 is arranged corresponding to the symmetrical center of the splitter plate 221. The distance between the lower edge of the splitter plate 221 at the symmetrical center position and the bottom wall of the sewage tank 24 is the largest, so as to facilitate the flow to the filtrate assembly through the lower edge here. The airflow of 26 can flow into the filtrate assembly 26 more quickly, avoiding impact on the liquid accumulation area; and the airflow after detouring along the splitter plate 221 has a reduced flow rate, and is drawn by the suction of the fan 50 to bypass the splitter plate 221 and then directly towards the filtrate assembly. 26 flow, so that the probability of impacting the liquid accumulation area is smaller, the flow rate is gentler, and it is also conducive to gas-liquid separation.

Optionally, the diverter plate 221 can also be in a special shape such as a wave shape, which can divert the air flow. This application does not impose any restrictions on the specific structure of the diverter plate 221 .

Further, the clean water tank 22 also includes guide plates 223 provided on both sides of the first air flow port 201. The diverter plate 221 is connected between the two guide plates 223. The guide plates 223 are used to guide the air flow to the filtrate assembly 26. The flow of air into the guide plate 223 also facilitates the separation of gas and liquid, thereby facilitating the collection of sewage in the sewage bin 24. Since the splitter plate 221 and the guide plate 223 are plate structures, they have a smaller probability of retaining sewage, which allows almost all the sewage to be collected. Collected in sewage tank 24.

In this embodiment, the guide plate 223 is arranged in an inclined manner, that is, the guide plate 223 is an inclined plate relative to the horizontal plane, and the two guide plates 223 are inclined toward each other in a figure-eight shape. The diverter plate 221 and the filtrate assembly 26 are arranged on the two guide plates. Between the plates 223, flow can be directed to the filtrate assembly 26 more efficiently.

The axial direction of the first airflow port 201 is inclined relative to the bottom wall of the sewage chamber 24, so that the initial flow direction of the airflow entering the sewage chamber 24 through the first airflow port 201 is toward the lid 28 covering the clean water bin 22, that is, The first airflow port 201 also guides the initial direction of the airflow so as not to impact the liquid accumulation area of the sewage tank 24, which can further reduce the probability of the airflow impacting the liquid accumulation area causing sewage to splash.

Furthermore, a water level detector 203 is provided on the side of the clean water tank 22 facing the sewage tank 24. The water level detector 203 is used to detect the liquid level in the sewage tank 24, so that when the liquid level in the sewage tank 24 reaches the preset water level, Send an alarm to remind users to clean the sewage bin 24 in time.

In this embodiment, referring to Figure 8, the filtrate assembly 26 includes a bracket 260 and a hypa 262 connected to the bracket 260. The bracket 260 is connected to the clean water tank 22, and the hypa 262 covers the filter port 204. Among them, Hypa 262 and the bracket 260 are floating in the direction toward the filter port 204, so that when the negative pressure suction airflow flows through the hypa 262 and the filter port 204, the hypa 262 and the filter port 204 form a self-sealing, so as to lift the hypa 262 The tightness with the filter port 204 and the upward floating of the Haipa 262 under negative pressure also help it stay away from the water surface of the sewage tank 24, which can reduce the Hapa 262 from being wetted by the splash of sewage.

Specifically, the bracket 260 includes a frame 261 and a grille 263 disposed on the window of the frame 261. The frame 261 is connected to the clean water tank 22. The grille 263 is correspondingly disposed at the filter port 204. The grille 263 is used to support the hypa 262. , the hypa 262 and the frame 261 are arranged in a floating manner; under the action of the air flow, the hypa 262 and the frame 261 form a self-sealing to indirectly seal the filter port 204.
