[0053] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0056] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0057] Reference Figure 1 and Figure 2The present invention provides a dust and gas separation element 5, including a cyclone cone 51 and a filter element 52 arranged at the outlet end of the cyclone cone 51; the cyclone cone 51 includes an outer cylinder 511 and an inner cylinder 512 arranged in the outer cylinder 511, and a plurality of dust and gas channels 510 are arranged between the outer cylinder 511 and the inner cylinder 512; the inner cylinder 512 is provided with a through hole 5130 leading to the filter element 52; it can be understood that the fluid flowing out of the dust and gas channel 510 enters the inner cylinder 512 through the through hole 5130, and the airflow after flowing into the through hole 5130 can be filtered again by the filter element 52 in the inner cylinder 512, and then flows out from the inner cylinder 512.

[0058] In the prior art, the filter element is usually a single-stage filter, and its filtering effect is poor; in order to improve this problem, the filter element 52 of the present application includes a cylindrical filter element 525 installed in the inner cylinder 512 and a partition 522 fixed in the cylindrical filter element 525. Figure 6 As can be understood, the interior of the cylindrical filter element 525 is divided into a first filter chamber 531 and a second filter chamber 532. After flowing into the through-hole 5130, the airflow first enters the first filter chamber 531 and undergoes primary filtration through the filter mesh surrounding the first filter chamber 531. After primary filtration, the airflow bypasses the partition 522 and undergoes secondary filtration through the filter mesh surrounding the second filter chamber 532 before entering the second filter chamber 532. This achieves dual-stage filtration and improves the filtration effect. Furthermore, the partition 522 also blocks dust and small droplets, facilitating their downward flow, thereby further improving the separation efficiency.

[0059] The cylindrical filter element 525 may be a filter element known to those skilled in the art, such as a filter screen, HEPA, or filter cloth, made of plastic or metal, and is not limited in this application.

[0060] As an embodiment of the present application, Figure 6-Figure 8 As shown, the outer edge of the partition 522 can be connected to the inner side of the cylindrical filter element 525 by abutting against it, and the two can be fixed together by conventional means such as gluing, interference fit or UV welding.

[0061] like Figure 9 As shown, the outer edge of the partition 522 can also extend to the outside of the cylindrical filter element 525, that is, the partition 522 has a flange 5221 extending outside the cylindrical filter element 525; under the obstruction of the flange 5221, the airflow after the first stage of filtration can be prevented from entering the second filter chamber 532 too quickly, allowing dust and small droplets and other pollutants intercepted by the partition 522 to have sufficient time to fall downward. Specifically, the flange 5221 can be provided by integrally forming the partition 522, the flange 5221, and the cylindrical filter element 525, or by configuring the cylindrical filter element 525 as two parts, each of which is fixedly connected to the partition 522. Other technical means known to those skilled in the art can also be used, and are not further limited in this application.

[0062] As an embodiment of the present application, the partition 522 can be configured as a flat plate (refer to Figure 6 ), can be set to a plate shape with a concave middle (spherical, inverted cone, multiple flat plates with the tips facing downwards, etc., refer to Figure 7 ), it can also be set to a plate shape with a convex middle (such as an upper spherical shape, a positive cone shape, a combination of multiple flat plates with the tips facing upwards, etc., refer to Figure 8 );

[0063] When the partition 522 is in the shape of a plate with a depression in the middle, it can guide the airflow after the first level of filtration upward to reduce the operating noise of the gas-liquid separator; when the partition 522 is in the shape of a plate with a convexity in the middle, it can guide the airflow after the first level of filtration downward, which can not only buffer the flow rate of the airflow flowing to the second filter chamber 532, but also help dirt such as dust and small droplets to fall downward.

[0064] As an embodiment of the present application, the filter element 52 further includes a first ring body 521 capable of supporting and connecting to the inner cylinder 512 . The first ring body 521 is disposed at one end of the cylindrical filter element 525 to enhance the overall strength of the filter element 52 .

[0065] As an embodiment of the present application, in order to strengthen the connection strength between the cylindrical filter element 525, the partition 522, and the first ring body 521, a plurality of reinforcing ribs 523 are provided on the first ring body 521, and at least one of the cylindrical filter element 525 and the partition 522 is connected to the above-mentioned reinforcing ribs 523; further, a second ring body 524 can also be provided at the lower part of the reinforcing rib 523 to support the lower end of the connected cylindrical filter element 525.

[0066] As an embodiment of the present application, in order to prevent the airflow from entering the inner cylinder 512 too quickly and affecting the separation rate, an inverted cone 513 is provided on the inner cylinder 512; a through hole 5130 is opened on the inverted cone 513, and the filter element 52 is provided in the inner cylinder 512 and at the upper part of the inverted cone 513.

[0067] Reference Figure 2 and Figure 3 As one embodiment of the present application, to prevent airflow from entering the through-hole 5130 too quickly, a skirt 5121 extends circumferentially from the lower portion of the inner cylinder 512. Preferably, the skirt 5121 at least partially vertically covers the inverted cone 513. The skirt can be completely closed circumferentially or discontinuous (composed of multiple small, spaced-apart skirts), both of which can prevent pollutants from flowing into the inverted cone 513.

[0068] Furthermore, the longitudinal section of the lower end portion 5122 of the skirt 5121 is configured to be pointed; based on this structure, the water vapor attached to the outer wall of the inner tube 512 is more likely to drip from the lower end portion 5122 of the skirt after condensing into water droplets, rather than sliding to the inner side of the skirt.

[0069] In a specific application scenario, the filter element 52 may rotate relative to the cyclone cone 51 along its circumference. To solve this problem, refer to Figure 4 and Figure 5 , a plurality of limiting grooves 5131 are provided on the inner cylinder 512 or the inverted cone cylinder 513 , and a limiting block 5241 that can be matched and plugged into the limiting groove 5131 is provided on the second ring body 524 .

[0070] Furthermore, to ensure that dust, small droplets, and other contaminants intercepted by the filter element 52 can flow smoothly out of the through-hole 5130 and fall downward, the stopper 5241 of the present application includes a first stopper 5242 capable of abutting one end of the limiting groove 5131 and a second stopper 5243 capable of abutting the other end of the limiting groove 5131. A gap 5244 is provided between the first stopper 5242 and the second stopper 5243. Furthermore, a notch 5132 is provided in the limiting groove 5131, communicating with the gap 5244. Consequently, dust, small droplets, and other contaminants flowing from the inner cylinder 512 and the cylindrical filter element 525 can pass through the gap 5244 and the notch 5132 and flow out of the through-hole 5130.

[0071] Reference Figure 2 、 Figure 3 and Figure 12 In order to support the dust and gas separator 5 , as an embodiment of the present application, a support column 514 is fixed to the lower portion of the cyclone cone 51 .

[0072] Specifically, the support 514 can be fixed to the outer cylinder 511, the inner cylinder 512, the skirt 5121 or the inverted cone 513 by connecting ribs (not shown in the figure). The space between adjacent connecting ribs can be regarded as a through hole 5130. Furthermore, the notch 5132 corresponds to the position of the connecting rib (that is, one end of the connecting rib is connected to the position of the notch). In this way, the pollutants flowing out of the notch 5132 can directly adhere to the connecting rib and flow downward along the length direction of the connecting rib, so that the airflow entering the through hole 5130 will minimize the impact on the downward movement of the pollutants.

[0073] Reference Figure 10-14 The present invention further provides a gas-liquid separator, comprising a dust barrel 101 and the dust-gas separator 5 in any of the above embodiments; the dust-gas separator 5 is arranged in the dust barrel 101, and the two together constitute a dust barrel assembly.

[0074] As an embodiment of the present application, the dust and gas channel 510 is arranged to be spirally inclined downward, so that when the fluid is discharged from the dust and gas channel 510, it can move downward and can be thrown to the periphery according to the centrifugal effect, thereby colliding with the inner wall of the dust tube 101; the kinetic energy of the dust and small droplets is reduced after the impact, so that they fall downward.

[0075] In one embodiment, the gas-liquid separator further comprises a housing 1 configured with an air inlet channel 41 and an air outlet channel 43, wherein a first cavity is formed inside the housing 1 and is fluidically connected to the air inlet channel 41; and a transfer channel 42 is formed for achieving fluid communication between the first cavity and the dust canister assembly;

[0076] The dust cylinder assembly is arranged in the first cavity and is in fluid communication with the air outlet channel 43 ; at least a portion of the fluid entering the first cavity through the air inlet channel 41 enters the transfer channel 42 after bypassing the dust cylinder assembly.

[0077] The above-mentioned fluid in this application can be a clean airflow or an airflow entrained with pollutants; the pollutants are at least one of dust, solid pollutants (such as cigarette butts, paper scraps, rice grains, etc.), and dirty liquids (such as orange juice, dirty water, egg liquid, etc.).

[0078] It can be understood that the dust cup assembly is constructed with a second cavity 1010 (i.e., the internal space of the dust cup 101) that is not directly connected to the first cavity; when the fluid flows in the first cavity, part or all of the fluid needs to bypass the outer surface of the dust cup assembly before flowing into the transfer channel 42.

[0079] Specifically, the outer peripheral surface at least includes a portion of the outer peripheral surface that is wound in a clockwise direction or a portion of the outer peripheral surface that is wound in a counterclockwise direction.

[0080] Based on the above arrangement, the fluid's travel path in the first cavity is lengthened, that is, the fluid trajectory from the outlet end of the air inlet channel to the inlet end 421 of the transfer channel is lengthened; in this way, the dirt entrained in the airflow can also more fully collide with other obstructive components such as the inner wall of the outer shell and the outer wall of the dust tube assembly to dissipate kinetic energy, thereby falling and being stored at the bottom of the first cavity.

[0081] It is worth noting that, referring to Figure 14 The fluid enters the dust and gas passage 510 directly through the transfer passage outlet 422. The dust canister 101 is disposed within the first cavity, and the outer peripheral surface of the dust canister assembly serves as the outer wall of the dust canister 101. The second cavity 1010 can store dust and small droplets that are discharged from the dust and gas passage 510 and collide with the inner wall of the dust canister 101. The airflow separated from the dust and small droplets then flows through the inner cylinder 512 to the air outlet passage 43.

[0082] As an embodiment of the present application, the dust cylinder assembly and the transfer channel inlet end 421 are basically arranged along the width direction of the gas-liquid separator; it is understandable that the dust cylinder assembly is arranged in the first cavity, and along the width direction of the gas-liquid separator, the transfer channel inlet end 421 is arranged on one side or the other side of the dust cylinder assembly. The outlet end of the air inlet channel is constructed not to face the transfer channel inlet end 421; it is understandable that the airflow discharged through the outlet end of the air inlet channel has an outlet direction (the initial flow direction when the airflow is discharged), and the airflow introduced through the inlet end of the transfer channel has an introduction direction (the direction of the airflow when entering the inlet end of the transfer channel), and the space formed by the outlet end of the air inlet channel along the outlet direction does not intersect with the space formed by the inlet end of the transfer channel along the introduction direction. This allows the fluid to flow to the transfer channel inlet end 421 too quickly, thereby reducing the probability of pollutants being directly sucked into the inlet end of the transfer channel.

[0083] refer to Figure 11-13 In a preferred embodiment, the outlet of the air inlet channel is substantially facing away from the inlet of the transfer channel. With the left-right direction defined as the width of the gas-liquid separator, the dust cup assembly is substantially positioned to the left of the transfer channel inlet 421, while the outlet of the air inlet channel is positioned in front of or behind the dust cup assembly and substantially facing left. This structure maximizes the fluid's path around the dust cup assembly, thereby improving the separation efficiency of the gas-liquid separator.

[0084] Furthermore, the transfer channel inlet end 421 can be basically arranged downward in the vertical direction, or can be basically arranged toward the right side.

[0085] As a preferred embodiment of this invention, all the fluids entering the first cavity bypass the outer peripheral surface of the dust cylinder assembly away from the inlet end 421 of the transfer channel, so that the travel path of all the fluids is lengthened and the collision and falling effect of the dirt is better.

[0086] In one embodiment, the housing 1 includes a lower housing 11 and an upper housing 12. The upper housing 12 can be opened relative to the lower housing 11 to facilitate handling of waste stored in the first cavity. A quick-release assembly is disposed between the lower housing 11 and the upper housing 12 to facilitate quick opening and closing of the upper housing 12 by the user. Specifically, the quick-release assembly can be selected from a locking structure, a snap-fit structure, a magnetic structure, or the like, known to those skilled in the art, or a combination of two or more, or in combination with a pivoting structure, and this application does not impose any further limitations thereon.

[0087] refer to Figure 13 As a preferred embodiment, the quick-release assembly of the present application includes a snap structure 132 and a pivot structure 131 .

[0088] As an embodiment of the present application, the transfer channel 42 and the air outlet channel 43 are arranged on the upper shell 12, and the air inlet channel 41, the first cavity, and the second cavity are arranged on the lower shell 11; in order to facilitate cleaning of the dust and gas separation component 5, it is detachably inserted into the upper shell 12.

[0089] The dust and gas separator 5 is prone to sinking when inserted into the upper shell 12. To solve this problem, the present application supports the pillar 514 from the bottom.

[0090] Furthermore, a support column 1011 may be provided in the dust cylinder 101 to support the pillar 514. The support column 1011 and the pillar 514 may both be solid and directly support each other; or at least one of the two may be provided in a sleeve shape and support each other in a plug-in manner.

[0091] When the upper shell 12 is closed, the support column 1011 is preferably configured as a sleeve in this embodiment, into which the support column 514 can be inserted. To facilitate insertion of the support column 1011 when the upper shell 12 is flipped and closed, the lower end of the support column 514 is chamfered or rounded. Furthermore, when the waste material flowing out of the notch 5132 flows downward along the length of the connecting rib, it can flow continuously along the support column 514 and the support column 1011 into the second cavity 1010.

[0092] When using a gas-liquid separator to clean dirt, the dirt that falls into the first cavity will inevitably shake. In order to prevent the dirt after shaking from being directly sucked away by the transfer channel inlet end 421, a baffle 111 is provided in the first cavity, and the baffle 111 is arranged at the lower part of the transfer channel inlet end 421.

[0093] refer to Figure 12 By setting the above-mentioned baffle 111, the first cavity can be understood as being decomposed into a first sub-cavity 1021, a second sub-cavity 1022 and a third sub-cavity 1023; wherein, the first sub-cavity 1021 is located on the left side of the baffle 111, the dust cylinder assembly is arranged in the first sub-cavity 1021, and the second sub-cavity 1022 and the third sub-cavity 1023 are respectively located on the upper side and the lower side of the baffle 111.

[0094] Under suction, the fluid enters the first sub-chamber 1021 from the air inlet channel 41 and moves along the airflow direction. During this process, some of the contaminants contained in the fluid may be dispersed into the first sub-chamber 1021, the second sub-chamber 1022, and the third sub-chamber 1023 due to the combined effects of gravity, collision, and other forces. However, it is obvious that the contaminants in the third sub-chamber 1023 are relatively less. Due to the presence of baffle 111, the suction force at the transfer channel inlet end 421 has a smaller effect on the contaminants in the first sub-chamber 1021 and the second sub-chamber 1022, thereby improving the separation efficiency of airflow, solids, and liquids.

[0095] In one embodiment, the baffle 111 has a first end close to the dust cup assembly and a second end away from the dust cup assembly, and the second end is configured to be higher than the first end, that is, the baffle 111 is tilted downward toward the dust cup assembly; in this way, when the dirt is in the third sub-chamber 1023, it may be introduced into the first sub-chamber 1021 or the second sub-chamber 1022 under the action of gravity, which not only facilitates the centralized collection of dirt, but also prevents garbage from being stored in the third sub-chamber, which has an adverse effect on the air path.

[0096] In specific application scenarios, the cross-section of the vent at the transfer channel inlet end 421 can be a regular shape such as circular, elliptical, rectangular, or irregular; however, in order to alleviate suction concentration and prevent a water pumping effect, the vent cross-section at the transfer channel inlet end 421 should be avoided as much as possible from being slit-shaped. Specifically, the ratio of the maximum length to the maximum width of the vent cross-section is no greater than 5; wherein the directions of the maximum length and the maximum width are perpendicular. For example, when the vent cross-section is rectangular, the length of the long side is defined as the maximum length, and the length of the short side is defined as the maximum width; when the vent cross-section is irregular, the longest vent cross-section length is defined as the maximum length, and then the maximum width is searched in a direction perpendicular to the direction of the maximum length.

[0097] In one embodiment, the gas-liquid separator provides suction through a motor, and the above-mentioned motor has a motor air inlet; the air outlet cross-sectional area of the transfer channel inlet end 421 is 1.5-2 times the area of the motor air inlet; this can limit and alleviate the suction at the transfer channel inlet end 421, which is conducive to water vapor separation.

[0098] In a specific application scenario, when the baffle 111 is close to the transfer channel inlet end 421, a pumping effect is easily formed, making it easier for pollutants to be sucked in from the transfer channel inlet end 421; when the baffle 111 is far from the transfer channel inlet end 421, the third sub-chamber 1023 is too large, and pollutants are easily moved into this space, thereby increasing the risk of pollutants flowing out from the transfer channel inlet end 421.

[0099] In this application, a first spacing d is defined between the transfer channel inlet 421 and the baffle 111. This first spacing d is the minimum spacing between the transfer channel inlet 421 and the baffle 111. The first spacing d is 12-20 mm, preferably 15 mm. Based on this range, the distance between the baffle 111 and the transfer channel inlet 421 is optimized.

[0100] In one embodiment, a max line 1024 is provided on the housing 1 for indicating the maximum volume of pollutants contained in the first cavity; the max line has a second distance c from the second end and a third distance b from the bottom of the first cavity; and the first end has a fourth distance a from the bottom of the first cavity.

[0101] The third spacing b is related to the preset design; for example, when the maximum volume of the pollutants contained in the preset first cavity is 1000 ml and the cross-sectional area of the first cavity is 400 cm2, then the height of the max line from the bottom of the first cavity is 2.5 cm.

[0102] Furthermore, the first spacing d is 1 / 3-1 / 2 times the second spacing c, which prevents the liquid from being too close to the baffle at the max line position and affecting the separation effect, and also prevents the liquid from being too far from the baffle at the max line position and wasting internal space.

[0103] Furthermore, the fourth spacing a is more than twice the third spacing b. By combining the above dimensions, the downward tilt angle of the baffle 111 can be limited to obtain a better separation effect.

[0104] In addition, the first end and the transfer channel inlet end 421 have a fifth spacing e in the horizontal direction, and the fifth spacing e is not less than 50 mm. Based on this, while ensuring the separation rate, it can effectively resolve the adverse effects caused by shaking and can also properly guide the direction of the fluid.

[0105] In one embodiment, the baffle 111 may be fixed to the upper shell 12 . In view of the inclined direction of the baffle 111 , such a configuration facilitates cleaning of the second sub-chamber 1022 and the baffle 111 when the upper shell 12 is opened.

[0106] refer to Figure 13 In another embodiment, the baffle 111 can also be fixed in the lower shell 11. In this way, the load when opening the upper shell 12 is lighter, and the dirt adhered to the baffle 111 will not be flipped into the transfer channel inlet end 421.

[0107] Furthermore, the baffle 111 can be fixed by UV welding, gluing, etc.; in the embodiment in which the baffle 111 is fixed on the lower shell 11, extension plates 1111 are provided at the joints between the first end and the inner wall of the lower shell 11 on both sides; when the dirty liquid in the first cavity shakes, it is easy to move upward along the inner wall of the lower shell 11. By providing the extension plate 1111, the movement amplitude of the dirty liquid can be effectively reduced, thereby preventing the dirty liquid from falling on the top of the baffle 111 and affecting the separation rate.

[0108] Reference Figure 15 and Figure 16 The present invention also provides a cleaning device, including the gas-liquid separator in any of the above embodiments; wherein, the cleaning device can be a mite remover, a floor scrubber, a vacuum cleaner, a sweeping robot, etc.

[0109] Taking the cleaning equipment as a vacuum cleaner as an example, it also includes a floor brush 2 and a body 3; wherein, the gas-liquid separator is arranged on the floor brush 2, one end of the body 3 is pivotally connected to the floor brush 2, and the floor brush 2 has an air intake channel 21 and an exhaust channel 22; one end of the air intake channel 21 is used to suck in dirt on the surface to be cleaned, and the other end is used to connect with the air intake channel 41, one end of the exhaust channel 22 is used to connect with the air outlet channel 43, and the other end is connected to the body channel 30 fluid in the body 3.

[0110] Furthermore, the floor brush 2 is formed with a mounting cavity 20, into which the gas-liquid separator is removably placed, thereby facilitating the removal of pollutants stored in the gas-liquid separator. Furthermore, the floor brush 2 may be provided with a locking structure to lock / unlock the gas-liquid separator, thereby ensuring airtightness and installation stability between the gas-liquid separator and the floor brush 2. Specifically, the locking structure may be at least one of a locking structure, a snap-fit structure, a magnetic structure, and the like, known to those skilled in the art.

[0111] In the present application, the vacuum cleaner also includes a motor, which can provide suction when powered on, so that the fluid flows through the floor brush, the gas-liquid separator, and the body.

[0112] In a specific application scenario, the motor can be directly fixed on the body 3, or integrated into a portable vacuum cleaner (small handheld), and suction to the fluid is provided by configuring the portable vacuum cleaner and the body to be fluidically connected.

[0113] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
