Cleaning equipment such as floor scrubbers, wet vacuum cleaners, and mopping machines are generally equipped with dirt treatment devices, floor brushes, and power devices. There is a suction channel in the ground brush, and a suction channel in the dirt treatment device, and the suction channel communicates with the suction channel. When the power unit is started, the sewage treatment device is in a negative pressure state, the sewage on the ground enters the suction channel through the suction channel of the ground brush, and the gas is discharged from the sewage treatment device through the air outlet of the sewage treatment device. The material is collected in the sewage treatment plant. Existing sewage treatment devices can only separate gas from solids and liquids, but cannot separate solids from liquids, making it inconvenient for users to clean. The sewage treatment device provided in the present application can separate the three-phase substances entering the sewage treatment device, which is convenient for users to clean. The sewage treatment device provided by this application will be described in detail below.

In some embodiments, please refer to FIG. 1 to FIG. 3 , the present application provides a separation device 12 , the separation device 12 is assembled in a box body 11 , and the box body 11 has a suction channel 111 communicating with the inside and outside of the box body 11 and an outlet. Tuyere 112. The separation device 12 includes a main body part 121 and a blocking part 124 . The main body 121 is disposed in the box body 11 , and defines a separation channel communicating with the suction channel 111 and the air outlet 112 with the inner wall of the box body 11 . The blocking member 124 is fitted on the main body 121 and blocks the flow path of all the air flowing from the suction channel 111 to the air outlet 112 . Wherein, all the airflow flowing out from the suction channel 111 turns to flow into the separation channel after hitting the barrier 124 , and flows out through the air outlet 112 after one or more stages of separation operations are performed.

When the separation device 12 is in actual operation, the airflow carries the sewage through the suction channel 111 towards the blocking piece 124 and then hits the blocking piece 124 , and turns around under the blocking of the blocking piece 124 . Due to the different motion inertia of solid-liquid-gas three-phase materials, the three phases will be separated after turning, which improves the separation efficiency of the three phases. At the same time, it turns and enters the separation channel. In the separation channel, the three-phase separation is basically relatively thorough after one or more stages of separation. At this time, the air flow flowing out through the air outlet 112 basically does not contain solid-liquid two-phase.

Compared with the prior art, the setting of the barrier 124 prevents the airflow from directly flowing to the air outlet 112, which not only enables the airflow to actively undergo three-phase separation after impact, which improves the separation efficiency, but also turns the airflow into the air after impacting the barrier 124. In the separation channel, the air flows out through the air outlet 112 after one or more stages of separation are further carried out in the separation channel. In this way, the separation path of solid-liquid-gas three-phase substances is extended, so that the air flow basically realizes three-phase separation when it reaches the air outlet 112, and a good separation effect can be achieved without setting consumables such as HEPA filter components at the air outlet 112. Not only the separation cost is low, but also the problem of low separation efficiency caused by the clogging of the filter components can be avoided, and the suction effect can be guaranteed.

In a state of use, the air outlet 112 is located above the separation device 12 .

In some embodiments, referring to FIG. 2 , the surface of the blocking member 124 facing the suction channel 111 is defined as a blocking surface, and the blocking surface is arranged eccentrically relative to the central axis of the suction channel 111 .

The blocking surface and the suction channel 111 are arranged eccentrically, and the airflow entering the flow guide cavity 1213 through the suction channel 111 mainly collides with the part near the edge of the blocking surface. At this time, the airflow entering the guide cavity 1213 and the airflow flowing out of the guide cavity 1213 mainly flow in two different regions, which reduces the interference of the incoming airflow on the flow field where the outflowing airflow is located. Moreover, due to the eccentric arrangement, the airflow has a certain centrifugal force. Under the action of the centrifugal force, the airflow can accelerate out of the guide cavity 1213 and enter into the separation channel, which helps to speed up the entire separation efficiency.

Wherein, the eccentric arrangement of the blocking surface relative to the central axis of the suction channel 111 means that the central axis of the blocking surface is located on one side of the central axis of the suction channel 111 , and the two are not coaxially arranged.

Further, the blocking surface is an arc surface protruding away from the suction channel 111 . At this time, setting the blocking surface as a curved surface can reduce the power loss of the airflow, thereby reducing the loss of wind pressure, and helping to reduce the requirement for high wind pressure of the fan. Specifically, the blocking surface is a hemispherical surface.

In some embodiments, the separation device 12 further includes a first filter element 122 , and the first filter element 122 is disposed in the separation channel and located downstream of the diverted air flow formed after hitting the blocking element 124 .

In actual operation, after the airflow hits the barrier 124, it turns and moves obliquely downward. During the movement, the gaseous substances in the three phases that are actively separated flow towards the air outlet 112 under the action of the suction force of the fan, while the liquid substances and solid substances Continue to move toward the first filter element 122, wherein most of the solid matter remains on the first filter element 122, and the liquid material flows to the bottom of the box body 11 under the action of its own gravity after passing through the first filter element 122, so as to realize the flow of air in the separation channel. Primary separation operation. After the primary separation operation, the gaseous substances, a small part of liquid substances and a small part of solid substances continue to move along the separation channel under the action of the suction force of the fan, and continue to be separated.

At this time, the first filter element 122 can separate the liquid and the solid, and can retain at least part of the solid, so that the effective separation of the solid and the liquid can be realized, and it is also convenient for the user to clean the box body 11 later.

In a specific embodiment, referring to FIG. 2 and FIG. 3 , the blocking member 124 is assembled in the main body 121 and divides the main body 121 to form a guide cavity 1213 communicating with the suction channel 111 . The main body 121 is provided with a lateral notch 1211 communicating between the diversion cavity 1213 and the separation channel. The lateral notch 1211 is located on the flow path of the diverted air flowing to the first filter element 122 formed after colliding with the blocking member 124 .

During actual operation, the air flow enters the guide cavity 1213 through the suction channel 111, and flows toward the blocking piece 124 and hits the blocking piece 124. The notch 1211 enters the separation channel. At this time, through the setting of the guide cavity 1213 and the lateral notch 1211, it can ensure that the diverted air flow enters the separation channel smoothly, and the overall structure is compact.

In some embodiments, the separation device 12 includes a second filter element 123 , which is disposed in the separation channel and located on the flow path of the air separated by the first filter element 122 to the air outlet 112 .

In actual operation, under the suction force of the fan, when the diverted airflow moves toward the first filter element 122, most of the solid matter and liquid matter are separated from the gaseous matter under the action of motion inertia and move toward the first filter element 122. Through the solid-liquid separation of the first filter element 122, the separation of most solid substances and liquid substances is realized, while a small part of solid substances and a small part of liquid substances carried by gaseous substances flow toward the second filter element 123 along the separation channel, and in the second The gaseous matter filtered by the filter element 123 flows toward the air outlet 112, while a small portion of solid matter and a small portion of liquid matter adhere to the second filter element 123, and move toward the first filter element 122 below under the action of gravity, and finally Solid matter remains on the first filter element 122 , liquid matter is collected at the bottom of the box 11 , and gaseous matter is discharged out of the box 11 , realizing the separation of gas, liquid, and solid three-phase substances.

At this time, the separation force of the three-phase substances can be further increased by setting the second filter element 123, and the separation efficiency can be improved. At this time, there is no need to additionally arrange consumables such as HEPA filter components at the air outlet 112 , and the separation cost is relatively low.

In a specific embodiment, referring to FIG. 2 and FIG. 3 , the blocking member 124 also divides the main member 121 to form an air-dispelling chamber 1212 communicating with the air outlet 112 , and the second filter member 123 covers the outer periphery of the air-dispelling chamber 1212 .

During actual operation, the gas separated by the second filter element 123 finally returns to the air outlet 112 through the air-dispelling cavity 1212 . At this time, the air-dispelling cavity 1212 communicating with the air outlet 112 is provided in the main body 121, which not only makes full use of the internal space of the main body 121 to extend the separation path, but also forms a hidden flow channel, and the overall structure is more compact.

Preferably, the wind-dispelling cavity 1212 is located below the air outlet 112 in the direction of gravity. At this time, the flow path between the wind-dispelling cavity 1212 and the air outlet 112 is the shortest and directly communicated, which helps to reduce wind pressure loss.

Wherein, the first filter member 122 may be a filter member with a relatively large filter aperture, such as a filter screen or a filter plate. The second filter element 123 may be a filter member with a smaller filter aperture, such as a filter screen, filter cotton, filter cloth, or the like. The filter aperture of the first filter element 122 is larger than the filter aperture of the second filter element 123 . The details are not limited, preferably, the first filter element 122 can retain most of the solid matter, and the second filter element 123 can only flow through the gaseous matter.

In a specific example, the main body 121 has a first end and a second end, the first end is located above the second end in the direction of the airflow path and is connected to the box body 11, and the first end has a wind outlet that communicates with the air outlet 11. Cavity 1212. The first filter element 122 is assembled on the second end. Specifically, the first end is located above (including directly above and obliquely above) the second end in the orientation shown in the figure.

In some embodiments, referring to FIG. 2 and FIG. 3 , the separation device 12 further includes a partition 125, the partition 125 is assembled in the separation channel, and separates a part of the separation channel in the direction of air flow to form at least two layers of separation channels, The other part of the separation channel and the main body 121 define an intermediate flow channel S3, and the separation channels of all layers communicate through the intermediate flow channel S3.

During actual operation, the air flows through the intermediate flow channel S3 between the separate flow channels of each layer, continuously rotates along the main body 121 and changes the flow direction during the flow process, forming a spiral-like flow path. In the turning process, under the action of centrifugal force, the liquid matter and solid matter in the airflow are thrown to the inner wall of the casing 11 or stay on the partition 125 (because the fluidity of the solid matter is poorer than that of the liquid matter, the solid matter generally Will stay on the dividing plate 125, the liquid material then flows to the bottom of the box body 11 along the side wall of the box body 11), and the gaseous material continues to flow along each flow channel, further separates the solid matter and the liquid matter in the airflow, and improves the separation effect.

At this time, the multi-layer separation channel is formed by the partition plate 125, which greatly prolongs the length of the air separation path, improves the separation effect, and improves the separation effect of solid matter and liquid matter at the same time. When the sewage treatment device 10 in this embodiment is actually used, the filter assembly provided at the air outlet 112 can be omitted, which greatly reduces the cost of consumables, and the middle flow channel S3 is connected to the separation flow channels of each layer, which can reduce the high wind pressure of the fan. The requirements should be low.

Specifically, the separator 125 is assembled on the outer peripheral side of the main body 121 , and at least two layers of separation channels are located on the eccentric side of the blocking member 125 . The other side of the outer periphery of the main body 121 and the inner wall of the box body 11 form an intermediate flow channel S3 , and the intermediate flow channel S3 is provided through the main body 121 along the axial direction.

Specifically in the embodiment, referring to FIG. 2 , there are at least two layers of separation channels with an upper layer separation channel S2 and a lower layer separation channel S1, the first filter element 122 is arranged in the lower layer separation channel S1, and the second filter element 122 is arranged in the lower layer separation channel S1. Inside the upper separation channel S2.

At this time, the first filter element 122 is set in the lower separation flow channel S1, and the second filter element 122 is set in the upper layer separation flow channel S2, which can fully utilize the length of the separation channel to separate the three-phase substances in the airflow.

It can be understood that the at least two layers of separation channels may also have at least one layer of intermediate layer separation channels located between the upper layer separation channel S2 and the lower layer separation channel S1, and the details are not limited.

Specifically, the second filter element 123 , the lateral notch 1211 and the partition plate 125 are located on the same side of the outer periphery of the main body element 121 , thereby forming a separate channel for turning the airflow. "The second filter element 123, the lateral notch 1211 and the partition plate 125 are located on the same side of the outer circumference of the main body part 121" from the perspective of the figure, it means that in a plane perpendicular to the axial direction of the main body part 121, the second filter Projections on the plane of the part 123 , the lateral notch 1211 , and the junction of the partition plate 125 and the main part 121 are at least partially coincident.

Of course, in other embodiments, the separation channel can also be a helical flow channel formed by other partitions helically arranged around the axial direction of the main body 121 , but the requirement for high wind pressure of the fan is higher. The specific configuration of the separation channel is not limited in this application.

Specifically in the embodiment, referring to FIG. 2 , there are gaps for liquid communication between the partition plate 125 and the side wall of the box body 11 , and between the first filter element 122 and the side wall of the box body 11 . At this time, the liquid substance adhering to the side wall of the box body 11 when moving through the separation channel can directly flow to the bottom of the box body 11 through the above-mentioned gap under the action of gravity, which facilitates the recovery of the liquid substance. Certainly, in other embodiments, the liquid substance adhering to the side wall of the box body 11 may also pass through the first filter element 122 and fall to the bottom of the box body 11 , which is not limited to the above method.

In some embodiments, the suction channel 111 is a straight channel in the direction of gravity. In this way, power loss and wind pressure loss can be reduced when the airflow flows.

The above separation device 12, through the setting of the blocking member 124, prevents the airflow from directly flowing to the air outlet 112, which not only strengthens the active three-phase separation of the airflow after the impact, improves the separation efficiency, but also diverts into the separation channel after colliding with the blocking member 124 In the separation channel, one or more stages of separation are further carried out before it flows out through the air outlet 112. In this way, the separation path of the solid-liquid-gas three-phase is extended, so that the airflow basically realizes the three-phase separation when it reaches the air outlet 112, and a good separation effect can be achieved without setting consumables such as HEPA filter components at the air outlet 112, not only The separation cost is low, and the problem of low separation efficiency caused by the clogging of the filter components can be avoided to ensure the suction effect.

In addition, some embodiments of the present application also provide a sewage treatment device 10, referring to Fig. 1 to Fig. 3, the sewage treatment device 10 includes a tank 11 and a separation device 12 provided in any of the above-mentioned embodiments. The box body 11 has the above-mentioned suction channel 111 and air outlet 112 communicating with the inside and outside of the box body 11 . Since the sewage treatment device 10 includes the above-mentioned separation device 12, it includes the beneficial effects of the above-mentioned separation device 12, which will not be repeated here.

In some embodiments, referring to FIG. 3 , the sewage treatment device 10 further includes a detection device 13, which is arranged in the box 11, and is used to obtain the content characteristics of the solid matter in the isolate obtained after the primary separation.

In actual operation, after the detection device 13 obtains the content characteristics of the solid matter in the isolate obtained after the primary separation, the content of the solid matter separated after the primary separation can be judged according to the content characteristics. When there is solid matter or the solid matter exceeds the standard, it indicates that the degree of dirt on the ground is heavy, and it is necessary to increase the rotating speed of the fan in the power unit 40 and the rolling brush motor in the ground brush 30 to increase the cleaning power. When there is no solid matter or the solid matter does not exceed the standard, it means that the degree of dirt on the ground is relatively light, and the rotating speed of the fan in the power unit 40 and the rolling brush motor in the ground brush 30 can be reduced to save energy and electricity.

In some embodiments of the present application, the detection device 13 includes a gravity sensor, and the content feature is a weight signal generated by solid substances on the first filter element 122 acquired by the gravity sensor. Alternatively, the detection device 13 includes an infrared sensor, and the content feature is an infrared signal obtained by the infrared sensor and reflected by the solid matter on the first filter 122 .

During actual operation, the content characteristics of the solid matter on the first filter element 122 can be acquired by a gravity sensor or an infrared sensor. Specifically, the gravity sensor may be arranged on the first filter element 122. When solid matter remains on the first filter element 122, it will fall on the gravity sensor. When the gravity of the solid matter acts on the gravity sensor, the gravity The sensor acquires the gravity signal of the solid matter. Specifically, the infrared sensor may be installed on the inner wall of the box body 11, and set toward the first filter 122. When there is a solid substance on the first filter 122, the infrared light generated by the infrared sensor is reflected by the solid substance and then is reflected by the infrared sensor.
