As described in the present application, the description of “first”, “second”, etc. is only for the purpose of description and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features defined as “first”, “second” can explicitly or implicitly include at least one of the features.

[0034] It should be further understood that the term “and / or” used in the specification and the appended claims of the present application refers to any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0035] Please refer toFigures 1 to 4 The embodiment of the present application provides a gas-liquid separation device 100, which comprises a shell 10, an input cylinder sleeve 20, an output cylinder sleeve 40 and a filter assembly 50. The shell 10 comprises a first containing space 11 and opposite first and second openings 10a and 10b.

[0036] Further, the input cylinder sleeve 20 is arranged in the first opening 10a, wherein a first port 20a of the input cylinder sleeve is located outside the containing space 11, and a second port 20b of the input cylinder sleeve is located inside the containing space 11.

[0037] Further, the flow guide 30 comprises a flow guide body 31 and a spiral guide groove 32 formed on the flow guide body 31, the flow guide body 31 comprises an air inlet 311 in communication with the spiral guide groove 32, the flow guide 30 is embedded in the input cylinder sleeve 20, and the spiral guide groove 32 cooperates with the inner wall of the input cylinder sleeve 20 to form a spiral flow channel.

[0038] It can be understood that, by embedding the flow guide 30 in the input cylinder sleeve 20 and forming the spiral flow channel by cooperation of the spiral guide groove 32 and the inner wall of the input cylinder sleeve 20, on the one hand, the spiral flow channel part can be easily machined due to the design of the spiral guide groove 32, and the machining process yield of the present application is higher and the cost is lower compared with the traditional spiral flow channel part, on the other hand, the structure is simple and reliable, which facilitates users and manufacturers to assemble, disassemble or maintain, and also reduces the risk of breakage of the traditional spiral flow channel caused by equipment vibration and collision, and improves the durability of the cleaning equipment.

[0039] For example, the input cylinder sleeve 20 can be sealingly sleeved on the circumferential side of the flow guide 30 by adhesion.

[0040] It can be understood that, by adhesion, the input cylinder sleeve 20 is sealingly sleeved on the circumferential side of the flow guide 30, the sealing effect of the spiral flow channel can be improved, so that the airflow in the spiral flow channel is stably accelerated, and the separation effect of the gas-liquid separation device 100 is further improved.

[0041] Further, the output cylinder sleeve 40 is arranged in the second opening 10b, a first port 40a of the output cylinder sleeve is located inside the containing space 11, a second port 40b of the output cylinder sleeve is located outside the containing space 11, and the first port 40a of the output cylinder sleeve corresponds to the second port 20b of the input cylinder sleeve.

[0042] It can be understood that by arranging the second port 20b of the input sleeve and the first port 40a of the output sleeve in the accommodation space 11, a water storage space can be formed in the accommodation space 11 by the cooperation of the outer wall of the sleeve and the inner wall of the shell that extends into the accommodation space 11, so that the gas-liquid separation operation can reduce the restrictions on the angle and the posture, expand the effective working space and the degree of freedom of the user when using the cleaning device, and improve the practicability and ease of use of the cleaning device.

[0043] For example, the first port 40a of the output sleeve can correspond to the second port 20b of the input sleeve and leave a distance corresponding to 0.2 to 2 times the diameter of the first port 40a of the output sleeve, thereby forming a throwing space. Under the premise of ensuring controllable gas flow rate and no backflow, the gas in the input spiral flow channel can be thrown into the accommodation space 11 by centrifugal force when passing through the throwing space, so as to avoid the liquid, droplets or solid particles entering the output sleeve 40, thereby realizing the effect of gas-liquid separation.

[0044] Further, in some embodiments, referring to Figure 3 and Figure 5 , as shown in Figure 3 and Figure 5 , the area of the first port 40a of the output sleeve can be smaller than the second port 20b of the input sleeve.

[0045] For example, the diameter of the first port 40a of the output sleeve can be 0.2 to 0.95 times the diameter of the first port 40a of the output sleeve.

[0046] It can be understood that by making the area of the first port 40a of the output sleeve smaller than the second port 20b of the input sleeve, the gas in the input spiral flow channel can be more easily thrown into the accommodation space 11 by centrifugal force, further avoiding the liquid, droplets or solid particles entering the output sleeve 40, and improving the effect of gas-liquid separation.

[0047] It can be further understood that the efficiency of gas-liquid separation can also be improved by optimizing the parameters of the spiral line of the spiral guide groove.

[0048] For example, the spiral guide groove can be provided along a spiral line, and the pitch of the spiral line can be 0.5-4 times the diameter of the spiral line.

[0049] In some embodiments, referring to Figure 5 , as shown in Figure 5 , the second port 20b of the input sleeve can include an expansion structure 21.

[0050] Further, the end of the flow guide body 31 close to the second port 20b of the input sleeve can form a flow guide cone 33.

[0051] It can be understood that the design of the expansion structure 21 and the flow guide cone 33 can help to reduce vortex, reduce pressure loss, reduce noise or increase gas flow rate, thereby improving the use performance of the cleaning device, and the design of the expansion structure 21 can further expand the throwing space and improve the gas-liquid separation efficiency.

[0052] Further, the expansion structure 21 or the second port 20b of the input cylinder sleeve can also form a pore structure, which further improves the gas-liquid separation efficiency.

[0053] In some embodiments, referring to Figure 3 , Figure 4 and Figure 5 , as shown in Figure 3 , Figure 4 and Figure 5 , the gas-liquid separation device 100 can also include a filter assembly 50, which can be arranged at the first port 40a of the output cylinder sleeve. The filter assembly 50 at least includes a waterproof layer.

[0054] Further, the waterproof layer can include a Hepa or a hydrophobic mesh.

[0055] For example, the Hepa or the metal mesh can be subjected to surface hydrophobic treatment by using a hydrophobic agent, thereby obtaining a Hepa or a hydrophobic mesh with hydrophobicity.

[0056] For example, the filter assembly 50 can also include a dustproof layer, which is used to prevent solid particles from entering the output cylinder sleeve 40 and entering the electronic components of the cleaning device, thereby reducing failure or damage.

[0057] In some embodiments, the shell 10 of the gas-liquid separation device 100 can be made of transparent material.

[0058] For example, the whole or part of the shell 10 can be made of transparent plastic materials such as AS, PC and PV, which is used to enable the user to see the liquid level in the containing space 11.

[0059] Further, the shell 10 can also be provided with a liquid level scale.

[0060] In some embodiments, the gas-liquid separation device 100 can also include a liquid level sensor arranged in the containing space 11, which is used to send a signal when the liquid reaches a preset amount or there is a risk of backflow.

[0061] It is understood that the first accommodating space 11 of the housing 10 can be used to accommodate components such as the input sleeve 20, the output sleeve 40, and the filter assembly 50, as well as the liquid separated during the gas-liquid separation process. To reduce the risk of backflow, the housing 10 can be made of transparent material and equipped with a liquid level scale, allowing users to observe the water level and actively prevent backflow. Alternatively, a liquid level sensor can be installed in the accommodating space 11 to send a signal when the liquid reaches a preset amount or when there is a risk of backflow, reducing the risk of backflow caused by excessively high liquid levels and avoiding problems such as component failure, damage, or reduced cleaning effect that may be caused by liquid backflow, thereby improving the safety, reliability, and performance of the cleaning equipment.

[0062] Furthermore, the gas-liquid separation device 100 also includes a drainage design.

[0063] For example, the output sleeve 40 can be detachably inserted through the second opening 10b;

[0064] Furthermore, the input sleeve 20 can be detachably inserted through the first opening 10a;

[0065] Furthermore, the housing 10 may also be provided with an openable or removable drain outlet.

[0066] Understandably, the drainage design, including the drain outlet and detachable mounting, allows users to easily drain the containment space 11 and perform maintenance and cleaning operations on components such as the filter assembly 50 within the containment space 11. This reduces the difficulty of maintenance and improves the reliability and maintainability of the gas-liquid separation device 100 and the cleaning equipment.

[0067] This application also proposes a cleaning device, which in some embodiments may include a gas-liquid separation device 100 as described in any embodiment of this application.

[0068] For example, the cleaning equipment can be a sweeper, floor scrubber, vacuum cleaner, or mite remover, etc., suitable for both industrial and commercial and home environments.

[0069] Furthermore, the cleaning equipment may also include a fan 60 connected to the gas-liquid separator 100 for accelerating the movement of gas.

[0070] For example, please refer to Figure 3 and Figure 5 ,like Figure 3 and Figure 5 As shown, the fan 60 can be connected to the second port 40b of the output sleeve.

[0071] It can be understood that by connecting the fan 60 to the second port 40b of the output sleeve, a negative pressure can be formed in the containing space 11 by the output sleeve 40, thereby accelerating the flow of gas and improving the efficiency of gas-liquid separation.

[0072] It can be further understood that when the fan 60 is started, the fan 60 can draw out the gas in the containing space 11 and form a negative pressure. At this time, the gas-liquid separation device 100 can suck the gas and liquid outside the first port 20a of the input sleeve into the spiral guide groove 32 through the gas inlet 311. The liquid and gas rotate after entering the spiral flow channel formed by the inner wall of the spiral guide groove 32 and the input sleeve 20. Due to the large mass of the liquid, the liquid in the spiral flow channel will move along the inner wall of the input sleeve 20 to the second port 20b of the input sleeve under the action of centrifugal force, and will be thrown out to the inner wall of the containing space 11 at the port plane of the second port 20b of the input sleeve due to the centrifugal force, while the air in the spiral flow channel will flow to the fan 60 through the output sleeve 40, thereby achieving the effect of gas-liquid separation.

[0073] In the case of not contradicting each other, those skilled in the art can combine and combine the different embodiments or examples described in the specification and the features of the different embodiments or examples.

[0074] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
