Gas-liquid separation structure and scrubber

Abstract

The utility model provides a gas-liquid separation structure and a scrubber. When the scrubber works, sewage and air enter a sewage cavity in a main body through a liquid inlet; the sewage cavity is communicated with the separation cavity of the separation part, so that gas is sucked into the separation cavity through the fan, and meanwhile, part of atomized sewage is sucked into the separation cavity together. In the separation cavity, the gas and the liquid begin to be separated. In the separation cavity, the gas and the liquid are separated due to density difference. Liquid remains at the bottom of the separation cavity due to gravity; and light gas flows upwards along the gas flow channel and is discharged through the fan. And the fan is communicated with the gas flow channel and is used for sucking and discharging the gas. Due to the effectiveness of the gas-liquid separation process, the discharged gas basically does not contain liquid, so that the risks of pollution and fan damage are avoided. By means of effective gas-liquid separation, liquid (especially atomized sewage) is prevented from being discharged from the air outlet along with gas, and therefore secondary pollution to the indoor environment is prevented.

Description

Technical Field

[0001] The present application relates to the field of floor scrubbing robots, and in particular to a gas-liquid separation structure and a floor scrubbing machine. Background Art

[0002] With the development of technology, more and more robots are being used in home life, such as floor scrubbers, automatic coffee machines, and electric curtains.

[0003] The function of the floor scrubber is to clean the indoor floor to achieve the purpose of cleaning and make the indoor environment cleaner.

[0004] During use, existing floor-scrubbing robots draw sewage and air into the sewage tank. As the air enters the tank, some of the sewage forms a mist under the influence of the high-speed air. This mist is then drawn into the blower along with the air and discharged through the air outlet. Because the air contains a mist of sewage, sewage flows out of the air outlet, affecting the cleaning effect of the floor-scrubbing robot. Furthermore, if the mist of sewage passes through the blower for a long time, it can leave residue on the blower, potentially causing it to enter the blower and burn, affecting the use of the floor-scrubbing robot.

[0005] At the same time, the sewage flowing out of the air outlet will remain in the room, where it is very easy to ferment and breed bacteria, seriously affecting the health of people indoors. Utility Model Content

[0047] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0048] It should be noted that when a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component.

[0049] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0050] An embodiment of the present application provides a gas-liquid separation structure 100, comprising:

[0051] The main body 110 is provided with a liquid inlet 110a and a sewage chamber 110b communicating with the liquid inlet 110a;

[0052] The separator 120 has a separation chamber 120a and a gas flow channel 120b in communication with the separation chamber 120a. The separator 120 is in communication with the sewage chamber 110b.

[0053] a fan 130 , communicating with the gas flow channel 120 b ;

[0054] The gas with mist-like sewage enters the separation chamber 120a, so that the gas enters the gas flow channel 120b, and the liquid is located in the separation chamber 120a to perform gas-liquid separation.

[0055] Please refer to Figure 1-Figure 7 In this embodiment, when the floor scrubber is working, sewage and air enter the sewage chamber 110b in the main body 110 through the liquid inlet 110a;

[0056] The sewage chamber 110b is connected to the separation chamber 120a of the separator 120, so the gas is sucked into the separation chamber 120a through the fan 130, and at the same time, part of the atomized sewage is also sucked into the separation chamber 120a. In the separation chamber 120a, the gas and liquid begin to separate.

[0057] In the separation chamber 120a, the gas and liquid are separated due to the difference in density. The liquid remains at the bottom of the separation chamber 120a due to gravity, while the lighter gas moves upward along the gas flow channel 120b and is discharged through the fan 130.

[0058] The blower 130 is in communication with the gas flow passage 120 b to draw in the gas and discharge it. Due to the effectiveness of the gas-liquid separation process, the discharged gas is substantially free of liquid, thereby avoiding the risk of contamination and damage to the blower 130 .

[0059] Through effective gas-liquid separation, liquid (especially atomized sewage) is prevented from being discharged from the air outlet along with the gas, thereby preventing secondary pollution to the indoor environment.

[0060] Since sewage does not enter the interior of the fan 130 , the risk of the fan 130 being damp or damaged by liquid residue is reduced, thereby extending the service life of the floor scrubbing robot.

[0061] The gas-liquid separation structure 100 ensures that the air exhausted by the floor scrubber during operation is clean, thereby improving the cleaning effect of the entire equipment and reducing subsequent cleaning and maintenance workload.

[0062] The gas-liquid separation structure 100 prevents bacterial growth and air pollution, and protects the health of users, especially when used in indoor environments.

[0063] It should be noted that the main body 110 is a shell; the liquid inlet 110a is a liquid inlet channel, which is connected to the inlet of the roller brush of the floor scrubber to absorb the liquid on the external ground and the liquid on the roller brush; the sewage cavity 110b is the cavity of the sewage tank.

[0064] The separator 120 is a cavity structure, and a separation cavity 120 a and a gas flow channel 120 b are formed inside. The separation cavity 120 a is a cavity; and the gas flow channel 120 b is a channel communicating with the fan 130 .

[0065] The fan 130 is a high-speed fan, an exhaust fan 130 and the like. In this embodiment, a high-speed fan is used to draw external liquid into the sewage chamber 110b, and to draw air in the sewage chamber 110b into the separation chamber 120a and discharge it through the gas flow channel 120b.

[0066] In at least one embodiment of the present application, the separator 120 is provided with an air inlet 120c and a return port 120d communicating with the separation chamber 120a, and the direction from the return port 120d to the air inlet 120c is arranged in a vertically upward direction.

[0067] Please refer to Figure 1-Figure 7 In this embodiment, gas containing misted wastewater enters separation chamber 120a. Gravity causes the gas and liquid to separate. The gas flows upward through a predetermined flow path within separation chamber 120a, gradually separating from the liquid. Gravity, however, causes the liquid to sink to the bottom of separation chamber 120a, near the reflux port 120d.

[0068] The separated liquid is discharged from the separation chamber 120a through the reflux port 120d and flows back to the sewage chamber 110b. Meanwhile, the separated gas continues to flow upward, eventually passing through the air inlet 120c and entering the gas flow channel 120b to be discharged by the fan 130.

[0069] Since the direction from the reflux port 120d to the air inlet 120c is arranged in a vertically upward direction, it ensures that the liquid can be effectively separated from the gas and discharged through the reflux port 120d, thereby avoiding the liquid from being retained in the separation chamber 120a and affecting the separation efficiency.

[0070] The direction from the reflux port 120d to the air inlet 120c is arranged in a vertically upward direction, which fully utilizes the effect of gravity, so that the gas and liquid can be separated more quickly and effectively in the separation chamber 120a, thereby improving the efficiency of gas-liquid separation.

[0071] This helps prevent the liquid from flowing back to the gas inlet 120c during the separation process, thereby preventing the liquid from entering the gas flow channel 120b and ensuring the purity of the gas after separation.

[0072] It should be noted that the air inlet 120c is a through hole, and the return port 120d is a through hole, and the direction from the geometric center of the return port 120d to the geometric center of the air inlet 120c is arranged in a vertically upward direction.

[0073] In at least one embodiment of the present application, the separation chamber 120a includes a bottom surface 120e, the reflux port 120d is disposed close to the bottom surface 120e, and the air inlet 120c is disposed away from the bottom surface 120e.

[0074] Please refer to Figure 1-Figure 7 In this embodiment, the gas containing mist sewage enters the separation chamber 120a. Since the air inlet 120c is set in the upper area away from the bottom surface 120e, the gas first diffuses and flows in the separation chamber 120a after entering.

[0075] In the separation chamber 120a, the gas and liquid are separated by gravity. The liquid sinks under the action of gravity and gradually approaches the bottom surface 120e of the separation chamber 120a, while the gas flows upward and is ready to be discharged through the gas inlet 120c and into the gas flow channel 120b.

[0076] When the liquid is deposited on the bottom surface 120e of the separation chamber 120a, since the reflux port 120d is set close to the bottom surface 120e, the liquid can be quickly discharged into the sewage chamber 110b through the reflux port 120d, ensuring that the liquid will not stay in the separation chamber 120a for too long, preventing it from affecting the separation efficiency.

[0077] At the same time, the separated gas enters the gas flow channel 120b in the gas inlet 120c area away from the bottom surface 120e, and is discharged through the gas flow channel 120b and the fan 130, ensuring that the discharged gas is clean and does not contain liquid.

[0078] By placing the reflux port 120d close to the bottom surface 120e, the separated liquid can be quickly discharged from the separation chamber 120a, preventing the accumulation of liquid in the separation chamber 120a. This effectively avoids the interference of liquid retention on the separation process, thereby improving the separation efficiency.

[0079] The air inlet 120c is positioned away from the bottom surface 120e, ensuring that the gas containing the misted wastewater does not remix with the liquid deposited on the bottom surface 120e when entering the separation chamber 120a. This reduces the risk of secondary mixing of gas and liquid, helping to maintain the cleanliness of the gas flow channel 120b and the effectiveness of gas-liquid separation.

[0080] By rationally arranging the positions of the air inlet 120c and the reflux port 120d, the gas and liquid in the separation chamber 120a can be separated according to a predetermined path and process, the gas can be discharged smoothly, and the liquid can also be discharged in time, thereby improving the overall efficiency and effect of gas-liquid separation.

[0081] The bottom surface 120 e is the inner wall of the separation chamber 120 a on a side close to the bottom of the main body 110 .

[0082] In at least one embodiment of the present application, the separator 120 is further provided with a guide plate 121, which is arranged in the separation chamber 120a. The separator 120 is also provided with a connecting port 120f, which is connected to the separation chamber 120a. The guide plate 121 is arranged between the connecting port 120f and the air inlet 120c, and partially blocks the air inlet 120c.

[0083] Please refer to Figure 1-Figure 7 In this embodiment, the gas containing mist sewage enters the separation chamber 120a through the connecting port 120f. Due to the partial shielding effect of the guide plate 121, the gas containing mist sewage will not immediately enter the gas flow channel 120b from the air inlet 120c, but will pass through the separation of the separation chamber 120a. The gas is controlled when entering the separation chamber 120a, thereby realizing gas-liquid separation.

[0084] After entering the separation chamber 120a through the communication port 120f, the gas is directed along a specific path by the guide plate 121. During this separation process, the liquid, guided by the guide plate 121, moves downward due to gravity, while the gas moves upward. The gas flows along the predetermined path, gradually rising, ultimately entering the gas flow channel 120b through the gas inlet 120c. Meanwhile, the liquid, guided by gravity, is directed to the bottom of the separation chamber 120a.

[0085] After the liquid settles to the bottom of the separation chamber 120a, it flows out through the return port 120d and into the sewage chamber 110b. The provision of the guide plate 121 ensures that the liquid flows smoothly to the return port 120d, and prevents the gas containing the misted sewage from immediately flowing into the gas flow channel 120b from the air inlet 120c without separation.

[0086] The communication port 120f is used to connect the sewage chamber 110b with the through hole of the separation chamber 120a.

[0087] In at least one embodiment of the present application, the guide plate 121 includes a first blocking portion 1211 , a second blocking portion 1212 , and a third blocking portion 1213 , and the separation chamber 120 a includes a top surface 120 g disposed opposite to the bottom surface 120 e ;

[0088] One end of the first shielding portion 1211 is provided on the top surface 120g, and the other end thereof extends vertically toward the bottom surface 120e.

[0089] One end of the second shielding portion 1212 is connected to the first shielding portion 1211, and the other end is inclined from the first shielding portion 1211 in a vertical downward direction;

[0090] One end of the third shielding portion 1213 is connected to the second shielding portion 1212, and the other end is extended in the horizontal direction;

[0091] The first shielding portion 1211 , the second shielding portion 1212 , and the third shielding portion 1213 shield the air inlet 120 c .

[0092] Please refer to Figure 1-Figure 7 In this embodiment, the gas containing mist sewage enters the separation chamber 120a through the connecting port 120f and first encounters the first blocking portion 1211. After the airflow is blocked, it is forced to flow downward, and the liquid begins to settle due to gravity.

[0093] After passing through the first shielding portion 1211, the airflow continues to move downward and encounters the second shielding portion 1212. The inclined design of the second shielding portion 1212 guides the airflow to continue to flow downward, while causing more liquid to separate from the airflow and settle to the bottom of the separation chamber 120a.

[0094] After passing through the second shielding portion 1212, the airflow encounters the third shielding portion 1213 and is guided to flow horizontally. At this time, a small amount of liquid that may remain in the airflow is further separated, ensuring that the gas is fully dry and pure before entering the gas flow channel 120b.

[0095] After the triple shielding and guidance of the guide plate 121 , the liquid in the airflow is basically separated, and the pure gas enters the gas flow channel 120 b through the air inlet 120 c and is finally discharged by the fan 130 .

[0096] Through the complex air flow path, a more efficient gas-liquid separation effect is achieved, ensuring the purity of the gas entering the air inlet 120c and reducing the number of droplets entering the gas flow channel 120b.

[0097] Through the combination of the first, second and third shielding parts 1213, the airflow path is precisely controlled, reducing the risk of liquid backflow or contamination of the airflow.

[0098] The guide plate 121 not only protects the air inlet 120c, but also optimizes the gas-liquid separation process by guiding the airflow path, thereby enhancing the performance of the overall gas-liquid separation structure 100 and extending the service life of the equipment.

[0099] Since the liquid in the air flow is effectively blocked from entering the air inlet 120 c , the risk of corrosion and damage to the fan 130 and other key components is reduced, and the stability and durability of the gas-liquid separation structure 100 are improved.

[0100] The first shielding portion 1211 is a vertical plate arranged vertically, the second shielding portion 1212 is an arc-shaped plate arranged obliquely, and the third shielding portion 1213 is a horizontal plate arranged horizontally.

[0101] In at least one embodiment of the present application, the air inlet 120c and the communication port 120f are located on both sides of the first blocking portion 1211, and the first blocking portion 1211 blocks the air inlet 120c along the horizontal direction.

[0102] Please refer to Figure 1-Figure 7 In this embodiment, the gas containing mist sewage enters the separation chamber 120a through the communication port 120f. Due to the horizontal shielding effect of the first shielding portion 1211, the airflow is forced to flow along a predetermined path instead of directly flowing to the air inlet 120c.

[0103] As the gas flows through the separation chamber 120a, the liquid gradually separates and settles to the bottom of the separation chamber 120a, near the reflux port 120d. Since the air inlet 120c and the communication port 120f are located on either side of the first shielding portion 1211, the gas and liquid flow paths are effectively separated.

[0104] Air inlet 120c is horizontally blocked by first blocking portion 1211. Gas must bypass first blocking portion 1211 to enter air inlet 120c, separating gas and liquid and preventing liquid from entering air inlet 120c. Furthermore, communication port 120f is located on the other side of first blocking portion 1211, allowing gas containing misted wastewater to enter smoothly through communication port 120f and allowing liquid to be discharged through reflux port 120d without affecting the flow of gas through air inlet 120c.

[0105] The gas separated by the optimized path enters the gas flow channel 120b through the air inlet 120c and is finally discharged by the fan 130. During the whole process, the first shielding portion 1211 makes the gas-liquid separation process more efficient and avoids unnecessary mixing and interference.

[0106] By arranging the air inlet 120c and the communication port 120f on both sides of the first shielding portion 1211 respectively and utilizing the horizontal shielding effect of the first shielding portion 1211, the mutual interference between gas and liquid during the flow process is significantly reduced, thereby improving the separation effect.

[0107] The horizontal shielding of the first shielding portion 1211 ensures that the gas entering the air inlet 120c is fully separated, prevents liquid or incompletely separated gas-liquid mixture from entering the air inlet 120c, and improves the purity of the exhaust gas.

[0108] In at least one embodiment of the present application, the guide plate 121 divides the separation chamber 120a into a separation channel 120h and an air outlet channel 120i, the separation channel 120h is formed by tilting from top to bottom in the vertical direction, and the air outlet channel 120i is formed by tilting from bottom to top, the separation channel 120h is connected with the air outlet channel 120i, the air inlet 120c is located in the air outlet channel 120i, the return port 120d and the connecting port 120f are located in the separation channel 120h; the connecting port 120f is arranged close to the top surface 120g.

[0109] Please refer to Figure 1-Figure 7 In this embodiment, the gas containing the mist-like sewage enters the separation chamber 120a through the communication port 120f and enters the separation channel 120h. The gas flows downward along the inclined path of the separation channel 120h.

[0110] In the separation channel 120h, due to the inclined design of the channel and the effect of gravity, the liquid in the gas gradually settles to the bottom of the separation chamber 120a, while the gas continues to flow forward.

[0111] The liquid that settles to the bottom of the separation chamber 120a is discharged to the sewage chamber 110b through the reflux port 120d, ensuring that the liquid in the separation chamber 120a does not accumulate.

[0112] After passing through separation channel 120h, the separated gas enters outlet channel 120i and flows along an upward inclined path. Due to the bottom-up design of outlet channel 120i, the gas does not carry away the liquid at the bottom during its flow, ensuring that the discharged gas is pure and pollution-free.

[0113] The pure gas enters the air outlet channel 120i through the air inlet and flows upward, and is finally discharged through the fan 130, completing the entire gas-liquid separation and discharge process.

[0114] Guide plate 121 divides separation chamber 120a into separation channel 120h and air outlet channel 120i, optimizing the gas-liquid separation process. The inclined design of separation channel 120h utilizes gravity to facilitate liquid sedimentation and cleanly discharge gas, improving separation efficiency.

[0115] The upward tilt of the air outlet channel 120i prevents liquid from re-entering the air flow, ensuring that the gas maintains high purity before being discharged.

[0116] The connection between the separation channel 120h and the air outlet channel 120i enables the gas to flow smoothly after separation, avoiding obstacles or interference in the air flow path.

[0117] The provision of the reflux port 120d and the communication port 120f ensures that the liquid can be discharged in a timely manner, and prevents the liquid from accumulating inside the separation chamber 120a, thereby reducing the impact on the gas-liquid separation process.

[0118] Secondly, the gas containing mist sewage enters the separation chamber 120a through the connecting port 120f and impacts the guide plate 121, causing part of the mist sewage to adhere to the inner wall of the separation chamber 120a, further improving the gas-liquid separation effect and making the separated gas cleaner and free of mist sewage.

[0119] In at least one embodiment of the present application, the gas-liquid separation structure 100 further includes:

[0120] The water pump 140 has one end connected to the reflux port 120d and the other end connected to the sewage chamber 110b.

[0121] Please refer to Figure 1-Figure 7 In this embodiment, during the gas-liquid separation process, the liquid settles to the bottom of the separation chamber 120a due to gravity. The liquid that settles to the bottom of the separation chamber 120a enters the water pump 140 through the reflux port 120d and is pumped into the sewage chamber 110b.

[0122] The water pump 140 is started to pump the liquid out from the bottom of the separation chamber 120a and transport the liquid to the sewage chamber 110b through the pipeline, ensuring that the liquid will not accumulate in the separation chamber 120a and affect the gas-liquid separation effect.

[0123] The water pump 140 delivers the liquid to the sewage chamber 110b, which serves as a collection container to store the liquid (sewage) for subsequent treatment or discharge.

[0124] As the water pump 140 continues to work, the liquid in the separation chamber 120a can be discharged in time, thereby maintaining the continuity and efficiency of the gas-liquid separation process and preventing the liquid from interfering with the separation effect.

[0125] By introducing the water pump 140 into the gas-liquid separation structure 100, it is ensured that the liquid in the separation chamber 120a can be discharged quickly and effectively, avoiding the interference of liquid accumulation on the separation process, thereby greatly improving the efficiency of gas-liquid separation.

[0126] In at least one embodiment of the present application, the gas-liquid separation structure 100 further includes:

[0127] The liquid blocking piece 150 is disposed at the communication opening 120f and blocks the communication opening 120f.

[0128] Please refer to Figure 1-Figure 7In this embodiment, when the liquid in the sewage chamber 110b approaches the communication port 120f, the liquid blocking sheet 150 acts as a physical barrier to prevent the liquid from directly entering the communication port 120f.

[0129] During the exhaust process, the fan 130 rotates to form a negative pressure on one side of the liquid blocking plate 150 so that the liquid blocking plate 150 does not block the communication port 120f, allowing the gas in the sewage chamber 110b to enter the separation chamber 120a through the communication port 120f.

[0130] By preventing liquid from entering the separation chamber 120 a , the liquid blocking plate 150 helps maintain the stability and efficiency of the gas-liquid separation process, ensuring that the gas can be discharged cleanly and the liquid is effectively collected in the sewage chamber 110 b .

[0131] The liquid blocking sheet 150 is a plastic sheet or a silicone sheet, and is disposed at the position of the communication port 120 f by bonding or rotational connection.

[0132] The liquid blocking plate 150 is located in the separation chamber 120a.

[0133] An embodiment of the present application provides a floor scrubber (not shown in the figure), comprising the gas-liquid separation structure 100 as described in any one of the above.

[0134] Please refer to Figure 1-Figure 7 In this embodiment, the floor scrubber includes the aforementioned gas-liquid separation structure 100 to effectively separate the gas and liquid in the mixture generated during the floor scrubbing process.

[0135] Ensure that gas and liquid can be effectively separated inside the scrubber, gas is discharged, and liquid is collected and processed. This prevents liquid from being discharged along with gas, thereby improving the cleaning effect of the scrubber.

[0136] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
