For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or two devices, components, or The internal communication between the components. For those of ordinary skill in the art, the specific meanings of the above-mentioned terms in this application can be understood according to specific circumstances.

In the process of practicing the embodiments of the present application, the inventor found that, at present, common cleaning equipment, such as vacuum cleaners, washing machines, sweeping robots, etc., are mainly composed of a cleaning system and a recovery system. The cleaning system usually includes a floor brush, and the recovery system usually includes The dust suction channel and the recycling bucket, and the cleaning system of some cleaning equipment also includes a sprinkler component, which is used to spray water to the roller brush component in the floor brush or the ground to achieve a better cleaning effect. When the cleaning equipment is working, the floor brush in the cleaning equipment can roll up the solid garbage and sewage on the ground, and under the action of the vacuum source, form a solid-liquid mixed airflow. The above-mentioned solid-liquid mixed airflow can enter the recycling bin through the dust suction channel . When the solid-liquid mixed air flow enters the recycling bin with a larger cross-sectional area from the dust suction channel with a smaller cross-sectional area, its flow speed will be reduced, and heavier solid waste and sewage can fall into the recycling bin under the action of gravity. The lighter gas can be pumped away by the vacuum source, so that the solid waste and sewage in the solid-liquid mixed gas flow are separated from the gas.

However, the existing technology only achieves the effect of separating solid garbage, sewage and gas, but the solid garbage and sewage in the solid-liquid mixed gas flow are not separated, which makes the solid garbage and sewage in the recycling bin still mixed together. When users need to clean up the garbage in the recycle bin, there are still many inconveniences. For example, if the user dumps the garbage in the recycling bin into the sewer or toilet, there is a risk that the solid garbage in the recycling bin will block the sewer or toilet. If the user dumps the garbage in the recycling bin into the trash can, there is a risk of water leakage. , Easy to soil the ground.

In the prior art, when the cleaning equipment is working, the sewage in the recycling bucket cannot be discharged. This makes that with the continuous operation of the cleaning equipment, more and more sewage will be collected in the recycling bucket, resulting in the usable volume of the recycling bucket. As it becomes smaller and smaller, the space of the separation chamber equivalent to the separation of water and gas will continue to decrease, which will eventually lead to a worsening of the effect of separating gas from the solid-liquid mixed gas stream.

Therefore, how to improve the cleaning equipment so that it can separate solid waste, sewage and gas in the solid-liquid mixed gas stream at the same time, and with the continuous work of the cleaning equipment, the separation effect will not be reduced, which becomes an urgent need in this field. Subject.

Obviously, the implementations described in this application are only a part of the implementations of this application, rather than all of the implementations. Based on the implementation in this application, all other implementations obtained by those skilled in the art without creative work fall within the protection scope of this application.

FIG. 1 is a cross-sectional view of a separation device 1 in an embodiment provided by this application, see FIG. 1.

In an embodiment of the present application, a separation device 1 is provided, which includes a main body 10 and a filter assembly 12. Wherein, the main body 10 has a separation cavity 11, and the main body 10 is also provided with an inlet 111, an air outlet 112 and a liquid outlet 113 passing through the separation cavity 11. The filter assembly 12 is connected to the inlet 111 and extends into the separation cavity 11. There is a first fluid channel between the inlet 111 and the filter assembly 12. There is a second fluid channel between the air outlet 112 and the filter assembly 12. There is a third fluid channel between the liquid outlet 113 and the filter assembly 12.

When in use, the airflow mixed with solid waste and sewage will pass through the first fluid channel and enter the filter assembly 12 from the inlet 111. The solid waste will be separated from the solid-liquid mixed airflow by the filter assembly 12, and will not enter the separation.内内。 In the cavity 11. The lighter air flows out of the separation chamber 11 from the air outlet 112 through the second fluid channel. As the airflow enters the separation chamber 11, the sewage will fall into the separation chamber 11 under the action of gravity, and then flow out of the separation chamber 11 from the liquid outlet 113 through the third fluid channel. The separation device 1 can effectively separate solid garbage, sewage and gas in the solid-liquid mixed gas flow, and no excess substances will be left in the separation chamber 11, which can avoid the space reduction of the separation chamber 11 due to the increase in the amount of sewage in the separation chamber 11 The problem that the separation effect becomes worse.

The technical solution provided by this application is to provide the filter assembly 12, the gas outlet 112 and the liquid outlet 113 in the separation device 1, and the filter assembly 12 is used to separate the solid and liquid in the solid-liquid mixed gas flow, and then the separated liquid It can be discharged from the liquid outlet 113, the gas can be discharged from the gas outlet 112, and the solids will remain in the filter assembly 12, thereby realizing the effect of simultaneously separating solid waste, sewage and gas in the solid-liquid mixed gas stream.

In an achievable embodiment of the present application, referring to FIG. 2, the separation device 1 can be applied to cleaning equipment. The cleaning equipment includes, but is not limited to, a handheld cleaning machine, a commercial mobile cleaning machine, a handheld vacuum cleaner, and a commercial Mobile vacuum cleaner, sweeping robot with automatic cleaning function. Taking the cleaning device in FIG. 2 as a washing machine as an example, the cleaning device includes a fuselage 2, and the separation device is provided on the fuselage 2. An achievable way of the fuselage 2 is that the fuselage 2 includes a suction unit and a recycling bin 24. The suction unit is communicated with the air outlet 112 on the separation device 1 through an air flow channel 23. The recovery barrel 24 is in communication with the liquid outlet 113 on the separation device 1 through a liquid channel. The recovery bucket 24 and the air flow passage 23 are not connected chambers. The suction unit is the vacuum source, and the suction unit can be realized by a vacuum motor, vacuum pump or fan.

The cleaning equipment further includes a floor brush 22 and a dust suction pipe 210, and the floor brush 22 includes a dust suction port 221 and a dust outlet 222. One end of the dust suction pipe 210 is detachably connected to the dust outlet 222, and the other end is detachably connected to the inlet 111 or the filter assembly 12. The dust suction channel 21 is formed by the dust suction pipe 210. In an achievable embodiment, the floor brush 22 is also provided with other functional units such as a rolling brush assembly, a water pump, etc., to cooperate with the floor brush 22 to complete the floor cleaning operation.

When the cleaning equipment is working, the suction unit is activated, and the suction unit works to form a negative pressure, thereby forming a suction from the dust suction port 221, the dust outlet 222, the dust pipe 210, the separation device 1, the air flow channel 23 to the suction unit Inhale air. Through the suction air flow, the floor brush 22 can suck the solid garbage and sewage on the ground into the dust suction pipe 210 through the dust suction port 221, and the sucked solid garbage and sewage can form a solid-liquid mixed air flow under the action of the suction unit , The solid-liquid mixed airflow can enter the filter assembly 12 through the dust suction channel 21, wherein the solid waste will be separated from the solid-liquid mixed airflow by the filter assembly 12, and will not enter the separation chamber 11. The lighter air flows out of the separation chamber 11 from the air outlet 112 through the second fluid channel, and is sucked away by the suction unit. As the airflow enters the sewage in the separation chamber 11, since the space volume of the separation chamber 11 is greater than the space volume of the filter assembly 12, when the sewage enters the separation chamber 11 from the filter assembly 12, the speed will be reduced, which makes the air mixed in the airflow. The sewage can fall on the bottom of the separation chamber 11 under the action of gravity, so as to realize the separation of gas and liquid. The sewage will fall into the separation chamber 11 under the action of gravity, and then flow out of the separation chamber 11 from the liquid outlet 113 through the third fluid channel, and then enter the recovery bucket 24. Thus, the solid waste, sewage, and gas in the solid-liquid mixed gas flow are separated by the separation device 1.

After solid garbage, sewage and gas are separated, it is convenient for users to classify and process different types of garbage, and reduce the disadvantages that occur after treatment together. For example, it can effectively prevent users from pouring sewage mixed with solid waste into the sewer or toilet together, reducing the risk of clogging the sewer and toilet. At the same time, it also prevents users from dumping sewage mixed with solid waste into the trash can, causing water leakage and soiling the ground.

Further, after the cleaning operation is completed, the dust suction tube 210 can be removed for cleaning, which can avoid the smell of the dust suction tube 210 due to the accumulation of dirt. At the same time, it can also be removed when the dust suction tube 210 is blocked. The lower dust suction pipe 210 facilitates dredging. For example, after the cleaning device has been used for a long time, a large amount of garbage may be attached to the inner surface of the dust suction pipe 210, and the garbage may remain in the dust suction channel 21 for a long time, which will rot and smell and produce peculiar smell. Therefore, the user can remove the dust suction pipe 210 for cleaning.

In an achievable embodiment, the dust suction tube 210 may be a spiral hose with elastic deformation function. As shown in FIG. 2, the dust suction pipe 210 may be exposed on the body 2 of the cleaning device. Of course, the dust suction pipe 210 can also be arranged inside the body 2. The dust suction pipe 210 is detachably connected to the floor brush 22 and the separating device 1, and the connection methods include but are not limited to: a quick release mechanism is provided between the dust outlet 222 and the filter assembly 12 and the dust suction pipe 210, such as quick release. Clips, quick-release fixtures, etc., can also be connected by threads or by fasteners.

In an achievable embodiment, there is a detachable connection structure between the filter assembly 12 and the inlet 111 of the separation chamber 11. Specifically, between the filter assembly 12 and the inlet 111 of the separation chamber 11, there is a mutual engagement structure. Through the foregoing engagement structure, the filter assembly 12 can be fixed at the inlet 111, so that the filter assembly 12 can be fixedly connected to the separation chamber. Cavity 11 on. Optionally, the filter assembly 12 and the inlet 111 may also be connected by threads or by fasteners.

When the solid-liquid mixed airflow passes through the filter assembly 12, the solid waste will be separated from the solid-liquid mixed airflow by the filter assembly 12 and will not enter the separation chamber 11. When the user needs to clean up the solid garbage remaining on the filter assembly 12, the user can remove the filter assembly 12 from the separation chamber 11 and dump the garbage on the filter assembly 12 into the trash can, so as to avoid the solid waste. Mixed with liquid garbage, the liquid garbage drips on the ground, causing the ground to be contaminated.

Furthermore, referring to FIG. 1 and FIG. 3A, in an embodiment of the present application, a possible implementation of the filter assembly 12 is that the filter assembly 12 includes a filter portion 121 and a base 122. The base 122 and the inlet 111 are detachably connected. The filter part 121 is located in the separation cavity 11, and one end is connected to the base 122 and communicates with the inlet 111. The base 122 is also provided with a dust suction inlet 1221, and the connection between the base 122 and the dust suction pipe 210 is realized through the dust suction inlet 1221. Objects entering the dust suction pipe 210, that is, objects collected in the dust suction channel 21, including solid waste and sewage and other waste, can enter the filter part 121 through the dust suction inlet 1221 on the base 122, and the filter part 121 can enter the filter part 121. The solid garbage and sewage are filtered, and the liquid and gas enter the separation chamber 11 through the dust suction inlet 1221 and the filtering part 121.

In a usage scenario, after the filter assembly 12 is used, the filter part 121 and the base 122 may have garbage that is difficult to clean, such as hair, rice grains, vegetable leaves, jam and other garbage, which remain in the filter for a long time. The inside of the filter part 121 and the base 122 may rot and smell, produce peculiar smell, and the above-mentioned garbage will also block the filter structure on the filter part 121, resulting in a poor separation effect of the filter part 121 on the solid-liquid mixed air flow, so it is necessary Consider the cleaning problem of the filter assembly 12.

In an achievable embodiment of the present application, there is a detachable connection structure between the filter portion 121 and the base 122, and a achievable way is that the filter portion 121 and the base 122 have mutually matching clips. With the above-mentioned locking structure, the filter part 121 can be fixed on the base 122. Further, the filter part 121 and the base 122 may also be connected by threads or by fasteners. After the user disassembles the filter assembly 12 from the separation chamber 11, the user can further disassemble the filter assembly 12 and disassemble it into two parts: the filter part 121 and the base 122. In this way, the user can disassemble the filter part 121 and the base 122. The base 122 is thoroughly cleaned, so as to avoid the situation that the filter 121 and the base 122 cannot be thoroughly cleaned, resulting in garbage remaining in the filter 121 and the base 122 and generating peculiar smell. At the same time, by thoroughly cleaning the filter part 121, the filter structure on the filter part 121 can also be kept unobstructed, so that the filter part 121 always has a good separation effect on the solid-liquid mixed air flow.

Further, in the embodiment of the present application, the filter portion 121 and the base 122 may also be an integral structure or a separate structure. The filter part 121 may be made of hard materials, such as metal materials, hard plastics, or other materials with an anti-corrosion layer. The filter part 121 can also be made of soft materials, such as nylon materials, soft plastics, or other materials with an anticorrosive layer. The filter portion 121 may be a mesh structure, such as a metal filter mesh, a plastic filter mesh, or a nylon mesh.

Further, in conjunction with FIG. 1, referring to FIGS. 3A to 3C, in the embodiment of the present application, another achievable manner of the filter part 121 is that the filter part 121 includes a hollow tube body 1211 and is covered on the hollow tube body End plate 1212 at one end of 1211. One end of the hollow tube body 1211 away from the end plate 1212 is connected to the base 122. In the hollow tube body 1211 and the end plate 1212, at least the hollow tube body 1211 is provided with a plurality of hole structures 1213. The hollow tube body 1211 and the end plate 1212 may be an integral structure, or may be a separate detachable connection structure. By providing the end plate 1212, the hollow tube body 1211 forms a structure with one end open and one end closed, and the hollow tube body 1211 is connected to the base 122 through an open end. The solid-liquid mixed air flow can enter the filter part 121 through one end of the opening, and the solid waste is separated and left in the filter part 121. Air and sewage enter the separation chamber 11 through the hole structure 1213.

According to different filtering requirements, not only the hole structure 1213 can be provided on the hollow tube body 1211, but also a plurality of hole structures 1213 can be provided on the end plate 1212. The hole structure 1213 on the end plate 1212 can make the air flow flow more smoothly, so as to perform solid-liquid-gas separation more effectively.

In the embodiment of the present application, a plurality of hole structures 1213 may be uniformly arranged on the tube wall of the hollow tube body 1211, or the hole structures 1213 may be arranged only in a partial area of the tube wall. Correspondingly, a plurality of hole structures 1213 may be uniformly arranged on the end plate 1212, or the hole structures 1213 may be arranged only in a partial area of the end plate 1212. That is, in the hollow tube body 1211 and the end plate 1212, at least the side of the hollow tube body 1211 facing away from the air outlet 112 is provided with a plurality of hole structures 1213. When the filter assembly 12 is installed on the main body 10, the hollow tube body 1211 is provided with a plurality of hole structures 1213 on the side facing away from the air outlet 112, and there is no hole structure 1213 on the side facing the air outlet 112. In this structure, the hollow The side of the tube body 1211 that is not provided with the hole structure 1213 obstructs the airflow, which makes the airflow more bends, so that the gas-liquid-solid separation effect is better.

In the embodiment of the present application, the hollow tube body 1211 may be a circular tube or a square tube body. The end plate 1212 may have a shape matching the hollow tube body 1211. When the hollow tube body 1211 is a square tube body, the hole structure 1213 may be provided only on the side of the hollow tube body 1211 facing away from the air outlet 112.

Continuing to refer to FIG. 3A and FIG. 3C, in the embodiment of the present application, the filtering component 12 can be implemented in multiple ways. One possible way is to refer to FIG. 3A, the end plate 1212 may be a hemispherical head, and the hemispherical head may be a solid structure or a hollow structure. After the solid-liquid mixed airflow enters the hollow tube body 1211, the hemispherical head can better withstand the impact of the solid-liquid mixed airflow and is not prone to deformation. When the hemispherical head has a hollow structure, it can also buffer the solid-liquid mixed air flow to prevent the solid-liquid mixed air flow from splashing or rebounding back to the dust suction inlet 1221, causing backflow. The wall of the hollow tube body 1211 has a plurality of penetrating hole structures 1213, and the plurality of hole structures 1213 can be evenly distributed on the tube wall. When the solid-liquid mixed airflow enters the hollow tube body 1211, the solid-liquid mixed airflow Liquid and gas can flow out of the hollow tube body 1211 through the above-mentioned pore structure 1213, thereby achieving the effect of separating the liquid from the solid-liquid mixed gas flow. Further, a hole structure 1213 can also be provided on the end plate 1212.

Further, the diameter of the hole structure 1213 on the tube wall can be set according to the diameter of the solid waste, so that the solid waste in the solid-liquid mixed air flow can be retained in the hollow tube body 1211 without passing through the above-mentioned hole structure 1213. So as to achieve the effect of separating solid waste from the solid-liquid mixed gas flow.

It should be particularly pointed out that when the solid-liquid mixed gas flow enters the hollow tube body 1211, the above-mentioned solid-liquid mixed gas flow can rub and collide with the wall of the hollow tube body 1211. In this way, the tiny liquid particles partially mixed in the gas It can be separated from the gas-liquid flow, and form large droplets, and finally flow out from the hollow tube body 1211 through the above-mentioned pore structure 1213. At the same time, since the wall of the hollow tube body 1211 is provided with a plurality of penetrating hole structures 1213, the hollow tube body 1211 also has the effect of screen separation for the gas and liquid flow, that is, the hollow tube body 1211 is equivalent to the screen , The gas can pass through the wire mesh, and the tiny liquid particles mixed in the gas will be intercepted and stay on the wire mesh, and under the action of gravity, they will gather to form large droplets, and finally pass through the above-mentioned pore structure 1213 from the hollow tube body. Out of 1211.

Further, another achievable way of the filter assembly 12 is that, referring to FIG. 3B, the end plate 1212 may be a hemispherical head, and the hemispherical head may be a solid structure or a hollow structure. Taking the section where the central axis a of the hollow tube body 1211 is located as the boundary, one side of the tube wall is a closed structure, and the other side of the tube wall has a plurality of hole structures 1213 penetrating through it. In this way, one side of the tube wall with a closed structure is equivalent to a baffle. When the solid-liquid mixed gas flow enters the hollow tube body 1211, it can block the gas flow and change the flow direction of the gas, and the tiny liquid mixed in the gas Due to inertia, the particles will continue to move to the side tube wall and eventually adhere to the side tube wall, so that the tiny liquid particles can be separated from the gas-liquid flow. It should be noted that when the filter assembly 12 of this structure is installed on the main body 10, the side of the hollow tube body 1211 that is a closed structure faces the air outlet 112, and the side facing away from the air outlet 112 is provided with multiple hole structures. 1213. Under this structure, the closed structure on the hollow tube body 1211 obstructs the airflow. When the airflow encounters obstacles, it needs to turn to avoid obstacles before it flows to the air outlet 112. After the airflow passes through the turn, the flow path becomes longer, so that The residence time of the airflow in the separation device 1 becomes longer, so that the gas-liquid-solid separation effect is better. Further, a hole structure 1213 can also be provided on the end plate 1212 on one side of the central axis a.

It should be noted that the arrangement of the hole structure 1213 on the hollow tube body 1211 may not be based on the section where the central axis a of the hollow tube body 1211 is located, or may be slightly higher than the line b where the line a is located. Alternatively, the line c, which is slightly lower than the position of line a, can be used as the boundary.

Further, another achievable way of the filter assembly 12 is that, referring to FIG. 3C, the end plate 1212 is a flat head, or an elliptical head or a dish-shaped head. For the method of providing the hole structure 1213 on the hollow tube body 1211 and the end plate 1212, please refer to the above-mentioned setting method in FIG. 3A and FIG. 3B, which will not be repeated here.

Further, in the embodiment of the present application, referring to FIGS. 1 and 3A to 3C, the dust suction inlet 1221 on the base 122 can also be arranged in multiple ways. One achievable way is, referring to FIG. 1, The dust suction inlet 1221 includes a connecting part protruding from the inlet 111, and the diameter of the connecting part may be smaller than that of the dust suction inlet 1221. When the caliber of the connecting part is smaller than the caliber of the dust suction inlet 1221, the connecting part can be sleeved in the dust suction tube 210, of course, the dust suction tube 210 can also be sleeved in the connecting part. The airflow enters the large-diameter channel from the small-diameter channel, and the speed drops, so as to achieve the effect of gas-liquid separation.

Another achievable way of the dust suction inlet 1221 is that, referring to FIGS. 3A to 3C, the dust suction inlet 1221 includes a connecting portion, and the diameter of the connecting portion may be equal to the diameter of the dust suction inlet 1221, which can make the solid-liquid mixed air flow easier Enter the filter 121.

In order to improve the filtering effect of the filter portion 121, in the embodiment of the present application, the hollow tube body 1211 includes at least two layers of tube walls, and each layer of the tube wall is provided with a plurality of pore structures 1213. Compared with a single-layer pipe wall, at least two layers of pipe walls have a longer path for airflow through the filter part 121 and a longer residence time. Relatively there are more pore structures 1213 per unit volume. Therefore, at least two layers of pipe walls have a greater impact on gas and liquid. Flow has a better screen separation effect. The solid-liquid mixed gas flow can be filtered multiple times through at least two layers of pipe walls, so that the solid waste separation effect is better. In order to better clean each layer of tube wall, each layer of tube wall can also be separated from each other for cleaning. After cleaning, they can be assembled together.

According to different filtration requirements, further, the pore diameters of the pore structures 1213 on the pipe walls of each layer can be the same or different. When the pore diameters are different, the pore diameter of the pore structure 1213 in the outer layer is larger than the pore diameter of the pore structure 1213 in the inner layer relative to the inner and outer orientations of the filter portion 121. The pore structures 1213 of different diameters can increase the collision and friction between the gas-liquid flow and the pipe wall, thereby improving the separation effect of the tiny liquid particles from the gas-liquid flow. And for the solid waste that rushes out of the inner tube wall due to the impact, it can be further intercepted.

According to different filtration requirements, further, the number of pore structures 1213 on each layer of the tube wall can be the same or different. When the number of pore structures 1213 is different, the number of pore structures 1213 in the outer layer is greater than the number of pore structures 1213 in the inner layer relative to the inner and outer orientations of the filter portion 121. The large number of pore structures 1213 located in the outer layer can speed up the liquid from the filter part 121 into the separation cavity 11, prevent the liquid and the solid from mixing for a long time, and improve the solid-liquid separation effect.

In order to further improve the solid-liquid-gas separation effect, in the embodiment of the present application, the positions of the hole structures 1213 on the tube walls of each layer are staggered. In this way, the hole diameter and number of the hole structure 1213 on each layer of the tube wall can be set accordingly according to different requirements. When the airflow passes through the pore structures 1213 that are misaligned with each other, it makes more turns, thereby effectively improving the separation effect.

In order to further improve the solid-liquid-gas separation effect, in the embodiment of the present application, a detachable first filter element is provided between two adjacent pipe walls. The first filter element can have a mesh structure or can be made of filter cotton. After the solid-liquid mixed air flow is filtered by the first filter element, the solid waste is further separated from the liquid, so that the mixed solid waste in the liquid becomes less, which facilitates the subsequent treatment of sewage.

Referring to Figures 1, 4 and 5, in the embodiment of the present application, a possible implementation of the main body 10 is that the main body 10 includes a top plate 101 and a bottom plate 102 disposed oppositely, and a side located between the top plate 101 and the bottom plate 102.壁103. According to different requirements, the shape formed by the sidewall 103 can be cylindrical, rectangular or other polygonal shapes. The top plate 101 and the bottom plate 102 have corresponding shapes that match the side walls 103.

At the same time, the inlet 111 is arranged on the top plate 101 or the side wall 103 according to different arrangement methods. In the separation device 1 shown in FIG. 1, the inlet 111 is provided on the side wall 103. In the separation device 1 shown in FIGS. 4 and 5, the inlet 111 is provided on the top plate 101. Further, when the inlet 111 is arranged on the side wall 103, the filter assembly 12 extends obliquely toward the direction of the bottom plate 102. Under the action of gravity, the liquid can converge along the inclined filter assembly 12, so that it is easier to flow out of the filter assembly 12, so that the liquid can better flow to the bottom of the separation chamber 11.

Correspondingly, the air outlet 112 is provided on the top plate 101 or the side wall 103. When the inlet 111 and the air outlet 112 are both arranged on the top plate 101, since the inlet 111 is used to install the filter assembly 12, in order to prolong the residence time of the solid-liquid mixed air flow in the separation device 1, the filter assembly 12 is arranged away from the air outlet 112 , That is, there is a certain distance between the inlet 111 and the air outlet 112, so that the filter assembly 12 is far away from the air outlet 112.

Furthermore, the liquid outlet 113 is provided on the side wall 103 or the bottom plate 102. When the separation device 1 is applied to cleaning equipment, the separation device 1 is used in conjunction with a recovery bucket 24, and the sewage separated by the separation device 1 can be collected through the recovery bucket 24. According to the different installation positions of the separation device 1 and the recovery barrel 24, the liquid outlet 113 on the main body 10 can be arranged on the side wall 103 or the bottom plate 102. For example, referring to FIG. 2 and FIG. 6, the separation device 1 can be arranged under the recovery barrel 24. At this time, the liquid outlet 113 can be arranged on the side wall 103 of the main body 10, and the liquid outlet 113 can be connected with the waste pipe 25 through the sewage pipe 25. The recovery barrel 24 is connected, and a negative pressure is generated in the recovery barrel 24 through the negative pressure source 26, so that the liquid in the separation chamber 11 is sucked into the recovery barrel 24 from the liquid outlet 113 through the sewage pipe 25. Of course, when the separating device 1 can be arranged below the recovery barrel 24, the liquid outlet 113 can also be arranged on the bottom plate 102 of the main body 10.

For another example, referring to FIG. 7, the separation device 1 can also be arranged above the recovery barrel 24. At this time, the liquid outlet 113 can be arranged on the bottom plate 102 of the main body 10, and the liquid outlet 113 can be provided with a filter or the bottom plate 102. A plurality of water passing holes are provided on the upper part, and the liquid outlet 113 is directly connected with the recovery barrel 24. The sewage in the separation chamber 11 can flow into the recovery bucket 24 through the liquid outlet 113 by gravity. Of course, a negative pressure source 26 can also be provided, and the negative pressure is generated in the recovery barrel 24 through the negative pressure source 26, so as to speed up the flow of liquid in the separation chamber 11 from the liquid outlet 113 into the recovery barrel 24. Of course, when the separation device 1 can be arranged above the recovery barrel 24, the liquid outlet 113 can also be arranged on the side wall 103 of the main body 10, communicated with the recovery barrel 24 through the sewage pipe 25, and then suck the sewage through the negative pressure source 26. .

In order to further improve the separation effect of the separation chamber 11, in the embodiment of the present application, referring to FIGS. 1, 4 and 5, at least one air flow baffle 114 is provided in the separation chamber 11 between the air outlet 112 and the filter assembly 12 . One end of the airflow baffle 114 is connected to the main body 10, and the other end extends along the extending direction of the filter assembly 12. As shown in Figure 1, Figure 4 and Figure 5, the air flow baffle 114 can be provided as one, and the air flow baffle 114 further obstructs the flow of gas and liquid into the separation chamber 11, extending the flow path to the air outlet 112 , So that the gas-liquid flow forms a baffle effect inside the separation cavity 11. Of course, multiple airflow baffles 114 may also be provided. Among the multiple airflow baffles 114, the extension directions of the two adjacent airflow baffles 114 are opposite, that is, the multiple airflow baffles 114 are arranged in a staggered manner in the separation chamber 11. Each airflow baffle 114 forms a corridor-like structure, so that the flow path of the airflow is S-shaped, and the flow direction can be changed many times, and the baffle effect of the airflow can be improved to obtain a better gas-liquid separation effect.

When the gas-liquid flow encounters the airflow baffle 114, the gas can flow away from the airflow baffle 114, and the liquid particles will continue to move forward due to inertia, and collide with the airflow baffle 114, and the liquid particles will adhere On the surface of the air flow baffle 114, and finally converge into large droplets and fall off the air flow baffle 114. By providing a gas flow baffle 114 inside the separation chamber 11, the gas entering the separation chamber 11 can be further separated from the gas and liquid, thereby reducing the liquid particles carried in the gas. Furthermore, in order to make the droplets on the airflow baffle 114 better fall off into the separation cavity 11, the airflow baffle 114 can extend obliquely toward the bottom of the separation cavity 11.

It should be noted that there is a gap between the extended end of the air flow baffle 114 and the side wall 103 of the main body 10 for air flow, and the air flow baffle 114 does not divide the separation chamber 11 into two chambers that are not connected to each other, namely The gas in the lower/upper space of the air flow baffle 114 can still flow into the upper/lower space of the air flow baffle 114, or the gas in the left/right space of the air flow baffle 114 can still flow into the right side of the air flow baffle 114/ In the left space. It should be noted again that the terms of the top plate 101, bottom plate 102, side wall 103, left, right, top, and bottom that appear in the embodiments of the present application representing the relative positions of space are all based on the viewing angle shown in the selected drawings as the reference system. .

Further, along the direction from the air outlet 112 to the filter assembly 12, the air flow baffle 114 at least shields the end of the filter assembly 12 at one end away from the inlet 111. The air flow rushing out from the end of the filter assembly 12 tends to be faster, and it is easy to directly flow out of the air outlet 112. The air flow baffle 114 can simultaneously block the air outlet 112 and the end of the filter assembly 12. When the gas flows from the filter assembly 12 to the gas outlet 112, the gas flow baffle 114 acts as a buffer, which slows down the flow rate of the gas and also forms a baffle effect, thereby obtaining a better gas-liquid separation effect.

In the embodiment of the present application, the air flow baffle 114 can be implemented in multiple implementation manners. For example, one achievable way is that the air flow baffle 114 has a straight plate structure. Another achievable way is that the air flow baffle 114 has an arc-shaped structure, and the concave surface of the arc-shaped structure faces the filter assembly 12 and wraps the filter assembly 12. Another achievable way is that the air flow baffle 114 has a cylindrical structure and surrounds the outer surface of the filter assembly 12, so that the air flow mixed with liquid particles flowing out of the filter assembly 12 will be baffled and then baffled. Entering the separation chamber 11, the airflow baffle 114 can form a better baffle effect on the flowing airflow. Furthermore, the air flow baffle 114 has a plurality of through holes, so that the air flow baffle 114 has the effects of screen separation and baffle separation at the same time.

Hereinafter, the different setting modes of the air flow baffle 114 in the separation device 1 will be described in further detail by way of example.

As shown in FIG. 1, in an achievable embodiment, the inlet 111 is located on the side wall 103 of the main body 10, the air outlet 112 is located on the top wall or the side wall 103 of the main body 10, and the liquid outlet 113 may be located on the side wall 103. Or on the bottom plate 102, the air flow baffle 114 is located below the air outlet 112 and extends along the extending direction of the filter assembly 12. The base 122 of the filter assembly 12 is connected to the main body 10 through the inlet 111, and the filter portion 121 extends into the separation chamber 11. The filter portion 121 may be substantially perpendicular to the side wall 103 of the main body 10, or extend obliquely to the direction of the bottom plate 102 . The air flow baffle 114 may be arranged opposite to the filter part 121 as shown in FIG. 1 and shield the filter part 121. Alternatively, the air flow baffle 114 may be provided on the same side as the filter part 121.

After the solid-liquid mixed gas flow enters the filter part 121 through the dust suction inlet 1221, the liquid in the solid-liquid mixed gas flow can flow to the bottom of the separation chamber 11, and the gas part flows out of the gas outlet 112 through the baffle 114 of the gas flow. The air outlet 112 is located on the top plate 101 of the main body 10, the filter part 121 is located below the air outlet 112, the separation chamber 11 is provided with an air flow baffle 114, and the air flow baffle 114 is located below the air outlet 112 and is located between the air outlet 112 and the filter Department 121 between. It should be pointed out that the filter part 121 may also be located above the air flow baffle 114 or below the air flow baffle 114. When the filter portion 121 is located above or below the air flow baffle 114, the side of the filter portion 121 facing the air outlet 112 can be a closed structure, that is, no hole structure 1213 is provided, thereby playing a role in obstructing air flow. The air flow baffle 114 may extend from the side wall 103 where the inlet 111 is located to the inside of the separation cavity 11, or may extend from another side wall 103 different from the side wall 103 where the inlet 111 is located to the inside of the separation cavity 11.

Under the action of the suction unit, the air flow mixed with liquid particles can enter the separation chamber 11 from the filter part 121. The air flow entering the separation chamber 11 will flow above the separation chamber 11 and be discharged through the air outlet 112. In the process, the tiny liquid particles carried in the air flow can be separated from the air flow under the action of gravity and fall into the bottom of the separation chamber 11. At the same time, the air flow baffle 114 can form a baffle effect on the rising air flow, and further affect the rising air flow. The gas flow separates the gas and liquid, thereby reducing the tiny liquid particles carried in the gas.

Further, when the air outlet 112 is located on the side wall 103 of the separation chamber 11, relative to the bottom plate 102, the height of the air outlet 112 on the side wall 103 is higher than the height of the inlet 111 on the side wall 103, so that the air outlet 112 is located at Above the filter 121. It should be pointed out that the air outlet 112 and the inlet 111 may be located on the side wall 103 on the same side of the separation chamber 11, or may be located on the side wall 103 on different sides of the separation chamber 11, respectively.

Further, the tube wall of the filter part 121 facing away from the air flow baffle 114 is provided with a plurality of hole structures 1213, and the tube wall of the filter part 121 close to the air flow baffle 114 is not provided with a hole structure 1213. For implementation, refer to Figure 3B. When the air flow mixed with liquid particles flows from the filter part 121 to the air outlet 112, the pipe wall on the side of the filter part 121 without the hole structure 1213 has a function similar to the air flow baffle 114, which can separate the gas from gas and liquid.

4 and 5, another possible implementation of the air flow baffle 114 is that the inlet 111 and the air outlet 112 are both located on the top plate 101 of the main body 10, and the air outlet 112 is away from the inlet 111, and the liquid outlet 113 can be Set on the side wall 103 or the bottom plate 102, the air flow baffle 114 is located between the air outlet 112 and the filter part 121.

The base 122 of the filter assembly 12 is connected to the main body 10 through the inlet 111, so that the filter portion 121 extends toward the inside of the separation cavity 11. The air outlet 112 is far away from the inlet 111. On the one hand, it is convenient to arrange the filter assembly 12, and on the other hand, it can make the filter part 121 and the air outlet 112 have a longer distance. When the gas mixed with liquid particles flows from the filter part 121 to the air outlet 112 When flowing, the tiny liquid particles carried in the gas can get enough space to escape from the gas flow. As shown in FIG. 4, the air flow baffle 114 may be connected to the bottom plate 102 and extend toward the top plate 101, or, as shown in FIG. 5, the air flow baffle 114 may be connected to the top plate 101 and extend toward the bottom plate 102. The air flow mixed with liquid particles can enter the separation chamber 11 from the filter part 121. The gas entering the separation chamber 11 will flow toward the gas outlet 112 and be discharged through the gas outlet 112. The liquid particles can be separated from the airflow under the action of gravity and fall into the bottom of the separation chamber 11. At the same time, the airflow baffle 114 can form a baffle effect on the flowing airflow, and further separate the airflow from gas and liquid, thereby reducing the amount of gas in the air. Carrying tiny liquid particles.

Further, as shown in FIG. 4, the air flow baffle 114 extends from the bottom plate 102 of the main body 10 toward the top plate 101. Relative to the bottom plate 102, the air flow baffle 114 is higher than the height of the end of the filter part 121, so that the air flow baffle 114 can at least shield the end of the filter portion 121. When the gas mixed with liquid particles enters the separation chamber 11 from the filter portion 121, the airflow baffle 114 can form a better baffle effect on the flowing airflow.

Further, as shown in FIG. 5, the airflow baffle 114 extends from the top plate 101 of the main body 10 toward the bottom plate 102. Relative to the bottom plate 102, the height of the end of the airflow baffle 114 is lower than the height of the end of the filter 121, so that As a result, the airflow baffle 114 can block the filter part 121. When the gas mixed with liquid particles enters the separation chamber 11 from the filter part 121, the airflow baffle 114 can form a better baffle effect on the flowing airflow. Of course, the height of the end of the airflow baffle 114 can also be higher than the height of the end of the filter 121. At this time, the airflow baffle 114 can also block the filter 121, and the airflow baffle 114 can still block the flowing airflow. Has a baffle effect.

In an achievable embodiment of the present application, the liquid outlet 113 may be located on the side wall 103 or the bottom plate 102 of the main body 10. The position of the liquid outlet 113 can be set according to the positions of the filter part 121 and the air flow baffle 114 in the separation chamber 11. As shown in FIG. 1, the filter portion 121 and the air flow baffle 114 are respectively located on different side walls 103 of the separation chamber 11. At this time, the liquid outlet 113 can be arranged on the side wall 103 where the air flow baffle 114 is located (ie, the separation in FIG. 1 The bottom of the left side wall 103) of the cavity 11 can also be provided on the bottom of the side wall 103 on the other side. Of course, it can also be provided on the bottom plate 102.

Or as shown in FIG. 4, the filter part 121 is located on the top plate 101 of the main body 10, the air flow baffle 114 extends from the bottom plate 102 of the separation chamber 11 toward the top plate 101, and the liquid outlet 113 can be arranged on the side wall 103 of the area where the filter part 121 is located. (That is, the bottom of the right side wall 103 of the separation chamber 11 in FIG. 4) may also be provided on the bottom plate 102 in the area where the filter portion 121 is located. Further, a through water hole may be provided at the junction of the air flow baffle 114 and the bottom wall, so that the liquid converging on the left side of the air flow baffle 114 can enter the right side of the air flow baffle 114 through the through water hole, and finally Flow to the liquid outlet 113. When the air flow baffle 114 is provided with a water passing hole, the liquid outlet 113 may be arranged at the bottom of the side wall 103 on the left side.

Or as shown in FIG. 5, the filter part 121 is located on the top plate 101 of the main body 10, and the air flow baffle 114 extends from the top plate 101 of the separation chamber 11 toward the bottom plate 102. At this time, the liquid outlet 113 may be arranged on the side away from the filter part 121. The bottom of the wall 103 (that is, the left side wall 103 of the separation chamber 11 in FIG. 5) may also be provided at the bottom of the side wall 103 near the filter portion 121 (that is, the right side wall 103 of the separation chamber 11 in FIG. 5), Of course, it can also be provided on the bottom plate 102.

Optionally, when the liquid outlet 113 is disposed on the bottom plate 102 of the main body 10, the liquid outlet 113 may be located directly below the filter part 121 to better accept the liquid flowing out of the filter part 121. The bottom plate 102 can be provided with a downwardly inclined funnel-shaped structure. With the continuous operation of the cleaning equipment, the liquid outlet 113 can continuously discharge the liquid collected in the separation chamber 11, so that the separation chamber in the separation chamber 11 is used for gas-liquid separation 11 The space will remain constant, so that the separation effect of the separation device 1 on the gas-liquid flow will not be reduced with the continuous work of the cleaning equipment.

Continuing to refer to FIG. 1, in the embodiment of the present application, the air outlet 112 has a shutter 115, and the shutter 115 shields at least part of the air outlet 112 along the direction from the inside of the separation cavity 11 to the outside of the separation cavity 11. The air outlet 112 can be blocked by the shutter 115, so as to further baffle and separate the air flow entering the air outlet 112. In the embodiment of the present application, the shutter 115 includes, but is not limited to, an L shape or a circular tube shape. A shutter 115 and an air flow baffle 114 can be provided in the separation chamber 11 at the same time, and the air flow baffle 114 and the air flow baffle 115 play multiple baffle effects on the air flow. One implementation is that the airflow baffle 114 is located below the shutter 115, of course, the airflow baffle 114 can also be arranged above the shutter 115. When the gas mixed with liquid particles flows from the filter part 121 to the air outlet 112, the airflow baffle 114 and the shutter 115 can form multiple barriers to the flowing airflow, thereby having a better baffle separation effect.

Further, in order to prevent the liquid or solid waste entering the separation chamber 11 from flowing out of the separation chamber 11 through the air outlet 112, in an achievable embodiment, as shown in FIG. 6, optionally, the shutter 115 and the air outlet There is a filtering structure between 112. Through the filtering structure, the air flow can be filtered again before the air flow flows out of the air outlet 112, so that the liquid or solid mixed in the air flow is separated from the air flow, and a better gas-liquid separation effect is achieved.

In the embodiment of the present application, the filtering structure can be realized in many ways. One way of realizing the filtering structure is that the filtering structure includes a supporting tube body and a second filter element detachably arranged in the supporting tube body, and the supporting tube body is provided with a second filter element. There are multiple filter holes. The filter chamber 116 is formed by the supporting tube body, and the second filter element is placed in the filter chamber 116, and the airflow entering the air outlet 112 is filtered again through the filter hole and the second filter element, so as to achieve a better gas-liquid separation effect. Another implementation of the filter structure is that the filter structure includes one or a combination of a filter mesh structure, a HEPA structure, and a filter cotton structure. The filter structure can be formed by stacking multiple layers of wire mesh.

Further, in order to detect the level of sewage in the separation chamber 11 and prevent excessive sewage in the sewage from affecting the separation effect of the separation chamber 11, in the embodiment of the present application, the separation chamber 11 is provided with a liquid level sensor. Relative to the bottom of the separation chamber 11, the height of the liquid level sensor is higher than the height of the liquid outlet 113. The liquid level in the separation chamber 11 can be detected by the liquid level sensor. When the sewage liquid level in the separation chamber 11 exceeds a preset liquid level threshold, the cleaning equipment can be used to speed up the discharge rate of the liquid outlet 113. The liquid level threshold can be set according to different requirements, and is not specifically limited in the embodiment of the present application.

One way of discharging liquid is that the liquid level sensor can cooperate with the suction system of the cleaning equipment to speed up the liquid discharge speed. When the liquid level sensor detects that there is too much liquid accumulated in the separation chamber 11, the liquid level exceeds the preset liquid level threshold. The liquid level sensor sends the liquid level information to the suction unit, and the suction unit stops working, so that the sewage in the separation chamber 11 will not continue to increase, so that the liquid outlet 113 has time to discharge the accumulated sewage.

Another way of discharging liquid is that the liquid level sensor can cooperate with the negative pressure source 26 of the cleaning equipment to speed up the liquid discharge speed. When the liquid level sensor detects too much liquid accumulated in the separation chamber 11, the liquid level exceeds the preset liquid level. Level threshold, the liquid level sensor sends liquid level information to the negative pressure source 26, and the negative pressure source 26 increases the power, so that the sewage in the separation chamber 11 can be discharged from the liquid outlet 113 faster.

It should be noted that the above two methods for accelerating the liquid discharge speed can be implemented separately or in combination according to different requirements, and are not specifically limited in the embodiments of the present application.

An achievable arrangement of the liquid level sensor is that the height of the liquid level sensor is lower than the height of the filter assembly 12 relative to the bottom of the separation chamber 11. In application, the height of the liquid level sensor does not exceed the height of the filter assembly 12. In this structure, the liquid level sensor will contact the liquid level before the filter assembly 12, and before the liquid level rises to the filter assembly 12, the liquid level sensor will The liquid level information is sent out, so that the suction unit suspends work or increases the power of the negative pressure source 26 to speed up the liquid discharge. The ideal effect is that the separation chamber 11 does not accumulate liquid.

By arranging a liquid level sensor in the separation chamber 11, when the cleaning device is working, no liquid is accumulated in the separation chamber 11 or the amount of liquid accumulated in the separation chamber 11 is small, so that the space in the separation chamber 11 for gas-liquid separation in the separation chamber 11 will remain It is relatively constant, so that the separation effect of the separation device 1 on the gas-liquid flow will not decrease with the continuous work of the cleaning equipment.

For example, when the cleaning equipment is cleaning the ground, there may be a lot of sewage on the ground, resulting in the solid-liquid mixed air stream generated when the cleaning equipment is working contains a lot of water. When the above-mentioned solid-liquid mixed air enters the separation device 1, The speed at which the liquid converges in the separation chamber 11 may exceed the speed at which the liquid is discharged from the liquid outlet 113. With the continuous operation of the cleaning equipment, more and more sewage collects in the separation chamber 11, and the volume of the separation chamber 11 decreases rapidly, which is equivalent to The cross-sectional area of the separation chamber 11 becomes smaller, which ultimately leads to a reduction in the separation effect of the separation device 1 on the gas-liquid flow.

After a liquid level sensor is installed in the separation chamber 11, the liquid level sensor can monitor the liquid level height of the liquid inside the separation chamber 11. When the liquid level sensor detects that the height of the liquid inside the separation chamber 11 exceeds the liquid level threshold, the liquid level sensor can The liquid level signal is sent to the negative pressure source 26, so that the negative pressure source 26 increases the working power, thereby accelerating the liquid discharge speed of the liquid outlet 113.

Further, continuing to refer to Figures 1 and 2, the embodiment of the present application also provides another separation device 1. It should be noted that the separation device 1 in the embodiment of the application is similar to the separation device described in the above-mentioned embodiment. 1 In the case that the structure does not conflict, mutual reference and reference can be made. The specific plan is as follows:

The separation device 1 includes a separation chamber 11 and a filter assembly 12; the separation chamber 11 has an inlet 111, an air outlet 112 and a liquid outlet 113, wherein the air outlet 112 is used to discharge air flow, and the liquid outlet 113 is used to discharge liquid; the filter assembly 12 It has a filter part 121 and a base 122, wherein the base 122 is connected to the separation chamber 11 through an inlet 111, the filter part 121 is connected to the base 122 and is located inside the separation chamber 11, and the base 122 has an external dust suction channel for connecting The dust suction inlet 1221 of 21, the filter part 121 is connected with the dust suction inlet 1221, and is used to filter objects entering from the dust suction inlet 1221.

In an achievable embodiment, the separating device 1 can be used as a component of the cleaning equipment and installed inside the cleaning equipment. The cleaning equipment can be a hand-held vacuum cleaner or a hand-held washing machine, or a sweeping robot with an automatic cleaning function. . The cleaning equipment includes at least a vacuum source (such as an air pump or a fan, etc.), a floor brush 22, a dust suction channel 21 and a separation device 1, and the vacuum source is in communication with the separation device 1, and the floor brush 22 and the separation device 1 pass through the dust suction channel 21 is connected. Specifically, the air outlet 112 in the separation device 1 communicates with the vacuum source through an airflow channel 23 arranged inside the cleaning device, and the dust suction inlet 1221 in the separation device 1 communicates with the dust suction channel 21.

When the cleaning equipment is working, the floor brush 22 can clean up solid garbage and sewage on the ground. The cleaned solid garbage and sewage can form a solid-liquid mixed airflow under the action of a vacuum source, and the solid-liquid mixed airflow can pass through The dust suction channel 21 enters the separation device 1, and the separation device 1 separates solid garbage, sewage and gas in the solid-liquid mixed gas flow.

In practical applications, objects (including solid waste and sewage and other waste) collected in the external dust suction channel 21 can enter the filter part 121 through the dust suction inlet 1221 on the base 122, and the filter part 121 can treat the solid waste entering it. Preliminarily filtering with sewage, leaving solid waste inside the filtering part 121, and liquid waste such as sewage can flow out through the filtering structure on the filtering part 121 and fall into the bottom of the separation chamber 11, thereby realizing the separation of solid waste and liquid waste At the same time, the gas can also enter the separation chamber 11 through the dust suction inlet 1221 and the filter 121.

It should be pointed out that at this time, the airflow entering the separation chamber 11 is still mixed with a large number of liquid particles. Since the cross-sectional area of the separation chamber 11 is larger than the cross-sectional area of the filter part 121, when the above-mentioned gas enters the separation chamber 11 from the filter part 121, the speed of the air flow will be reduced, so that part of the liquid particles mixed in the air flow can be affected by gravity. It will fall at the bottom of the separation chamber 11, so that the separation of gas and liquid can be achieved.

In an achievable embodiment, there is a detachable connection structure between the filter assembly 12 and the separation cavity 11. Specifically, between the base 122 of the filter assembly 12 and the inlet 111 of the separation chamber 11, there is a mutual engagement structure. Through the foregoing engagement structure, the base 122 can be fixed at the inlet 111, so that the filter assembly 12 can be It is fixedly connected to the separation cavity 11. Optionally, the base 122 and the inlet 111 may also be fixed as a whole through a screw connection.

Since sewage and other liquid garbage have flowed out of the filtering structure on the filtering part 121, only solid garbage remains in the filtering part 121. When the user needs to clean up the garbage remaining inside the filtering part 121, the user can remove the filter assembly 12 from the separation chamber. Remove the upper part 11, and pour the garbage inside the filter part 121 into the trash can, so as to avoid the situation that solid garbage and liquid garbage are mixed together, and the liquid garbage drips on the ground, causing the ground to be contaminated.

In one scenario, after the cleaning device has been used for a long time, there may be garbage that is difficult to clean up inside the filter 121 and the base 122, such as hair, rice grains, vegetable leaves, jam and other garbage, which remain for a long time. The inside of the filter part 121 and the base 122 may rot and smell, produce peculiar smells, and the above-mentioned garbage will also block the filter structure on the filter part 121, resulting in a poor separation effect of the filter part 121 on the solid-liquid mixed air flow. The cleaning of the filter assembly 12 needs to be considered.

In an achievable embodiment, in the filter assembly 12, a detachable connection structure is formed between the filter part 121 and the base 122. Specifically, the filter part 121 and the base 122 have a mutually matched engagement structure. , Through the above-mentioned engagement structure, the filter part 121 can be fixed on the base 122. Optionally, the filter part 121 and the base 122 may also be fixed as a whole through a screw connection. After the user disassembles the filter assembly 12 from the separation chamber 11, the user can further disassemble the filter assembly 12 and disassemble it into two parts: the filter part 121 and the base 122. In this way, the user can disassemble the filter part 121 and the base 122. The base 122 is thoroughly cleaned, so as to avoid the inability to clean the filter 121 and the base 122 thoroughly, resulting in garbage remaining in the filter 121 and the base 122 and generating peculiar smell. At the same time, by thoroughly cleaning the filter part 121, the filter structure on the filter part 121 can also be kept unobstructed, so that the filter part 121 always has a good separation effect on the solid-liquid mixed air flow.

In a scenario, after the cleaning equipment is used for a long time, a large amount of garbage may be attached to the inner surface of the dust suction channel 21. The above-mentioned garbage remains in the dust suction channel 21 for a long time, and it will also rot and smell and produce peculiar smell. Therefore, it is necessary to consider the cleaning of the dust suction channel 21.

In an achievable embodiment, the dust suction channel 21 may be a spiral hose with elastic deformation function. As shown in Figure 2, the dust suction channel 21 may be exposed on the body of the cleaning device. Optionally, a cover can be provided on the body of the cleaning device, and the dust suction channel 21 is installed inside the cover. When the user needs to clean the dust suction channel 21, the user can open the cover and take out the dust suction channel. twenty one.

The dust suction channel 21 and the separating device 1 are detachably connected together. Specifically, a quick release mechanism (such as a quick release buckle, a quick release clamp, etc.) can be set between the dust suction inlet 1221 and the dust suction channel 21, or the dust suction inlet 1221 and the dust suction channel 21 can be connected by a threaded connection. One. When the user needs to clean the dust suction channel 21, the user can quickly disassemble the dust suction channel 21 to separate the dust suction channel 21 from the separating device 1, and the end of the dust suction channel 21 connected to the floor brush 22 can also be used. The quick release mechanism is provided so that the user can completely separate the dust suction channel 21 from the cleaning equipment, and then rinse it with clean water.

Please refer to FIG. 3, which is a side view of three embodiments of the filter assembly 12 provided by this application. The filter part 121 is a hollow pipe with a closed structure at one end and an opening at the other end. The wall of the hollow pipe is provided with a plurality of hole structures 1213, and the open end of the hollow pipe is communicated with the dust suction inlet 1221 on the base 122, thereby So that the solid-liquid mixed air flow can enter the hollow pipe through the dust suction inlet 1221.

As shown in FIG. 3A, one end of the hollow pipe with a closed structure is a hemispherical head. When the solid-liquid mixed airflow enters the hollow pipe, the hemispherical head can better withstand the impact of the solid-liquid mixed airflow and is not easily deformed. The wall of the hollow pipe has a through hole structure 1213. The through hole structure 1213 is evenly distributed on the pipe wall. When the solid-liquid mixed gas flow enters the hollow pipe, the liquid in the solid-liquid mixed gas flow can pass through the hole structure 1213 from the hollow It flows out of the pipe to achieve the effect of separating the liquid from the solid-liquid mixed gas stream.

In practical applications, the diameter of the hole structure 1213 on the pipe wall can be set according to the diameter of the solid waste, so that the solid waste in the solid-liquid mixed air flow can be retained in the hollow pipe without passing through the hole structure 1213, thereby Realize the effect of separating solid waste from solid-liquid mixed gas flow.

It should be particularly pointed out that when the solid-liquid mixed gas flow enters the hollow pipe, the above-mentioned solid-liquid mixed gas flow can rub and collide with the pipe wall of the hollow pipe. In this way, part of the tiny liquid particles mixed in the gas can be removed from the gas-liquid flow. It separates and forms large droplets, and finally flows out of the hollow pipe through the above-mentioned pore structure 1213. At the same time, since the wall of the hollow pipe is provided with a plurality of penetrating hole structures 1213, the hollow pipe also has the effect of screen separation for the gas-liquid flow, that is, the hollow pipe is equivalent to the wire mesh, and the gas can pass through the wire mesh. The tiny liquid particles mixed in the gas will be intercepted and stay on the screen, and under the action of gravity, they will gather to form large droplets, and finally flow out of the hollow pipe through the above-mentioned pore structure 1213.

Optionally, as shown in FIG. 3B, one end of the hollow pipe with a closed structure is a hemispherical head, and the section where the central axis a of the hollow pipe is located is used as a boundary, one side of the pipe wall is a closed structure, and the other side of the pipe The wall has a hole structure 1213 through it. In this way, one side of the tube wall with a closed structure is equivalent to a baffle. When the solid-liquid mixed gas flow enters the hollow pipe, it can block the gas flow and change the flow direction of the gas.
