Description

Technical Field

[0001] The invention relates to the technical field of cleaning appliances, in particular to a leakage-proof cleaning device. Background Art

[0002] Cleaning equipment can use suction to remove contaminated fluids, assisting manual cleaning tasks. For example, a vacuum cleaner includes a separator (also called a filter) that filters dirty fluids and stores the remaining dust, large particles, and other debris. A dust bag is a common separator in vacuum cleaners. After fluid enters the dust bag, dust and large particles are temporarily trapped within it, while the cleaner, filtered fluid flows out through the bag's vents.

[0003] Dust bags can store a large amount of waste. Once the bag reaches a certain amount, it can be discarded and replaced with a new one, making waste removal easy. However, there's a risk of missing a bag when replacing it. If a bag is missing, the cleaning equipment loses its ability to filter and separate the dust-laden airflow. Turning on the cleaning equipment draws in a large amount of dust, affecting the motor and making it more difficult to clean out any waste that has entered the equipment. Summary of the Invention

[0111] To make the technical solutions and beneficial effects of the present disclosure more clearly understood, the following detailed description is provided by way of specific embodiments. The accompanying drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly illustrate the details of the local features. Unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application belongs.

[0112] In the description of the present disclosure, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "height", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of a simplified description of the present disclosure, and do not indicate that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be understood as a limitation to the present disclosure.

[0113] In this disclosure, the terms "first" and "second" are used solely for descriptive purposes and should not be construed as indicating the relative importance of the features indicated or the quantity of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly include at least one of such features. Throughout this disclosure, "plurality" means at least two, such as two or three, and "several" means at least one, such as one, two, or three, unless otherwise specifically defined.

[0114] In this disclosure, unless otherwise expressly defined, terms such as "installed," "connected," "connect," "fixed," and "disposed" should be interpreted broadly. For example, "connection" can mean fixed, removable, or integrated; it can mean mechanical or electrical; it can mean direct or indirect connection through an intermediary; it can also mean internal communication between two components or an interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on the specific circumstances.

[0115] In the present disclosure, unless otherwise explicitly defined, a first feature being “on,” “above,” “above,” “above,” “below,” “below,” or “below” a second feature may mean that the first feature is in direct contact with the second feature, or that the first feature and the second feature are in indirect contact via an intermediate medium. Moreover, a first feature being “on,” “above,” or “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. A first feature being “below,” “below,” or “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

[0116] In the embodiment of the present disclosure, the cleaning device includes but is not limited to a vacuum cleaner, and the "fluid" is a mixed fluid, which may refer to an air flow mixed with dust, garbage particles or debris.

[0117] Figure 1and Figure 2 The structural diagram of a horizontal vacuum cleaner is shown as an example.

[0118] like Figure 1 and Figure 2 As shown, the cleaning device provided by the embodiment of the present disclosure includes: a separation device 100 and a base 200, and the base 200 serves as a carrier for installing the separation device 100. Figures 3 to 4a As shown, the separation device 100 includes: a dust cup 110 and a separation component located in the dust cup 110, the separation component includes a cyclone separation component 120 and a dust bag separation component 140 ( Figure 4b As shown) at least one. Among them, the dust cup 110 has a first accommodating space 110a, a first inlet 101 for fluid to enter the first accommodating space 110a, and a first outlet 102 for fluid to flow out of the first accommodating space 110a. Usually, the base 200 also serves as a mounting carrier for the driving member 300. The driving member 300 is used to provide a suction flow. After the suction flow enters the first accommodating space 110a from the external space through the first inlet 101, the solid dirt such as dust, hair, and large particles of garbage in the fluid is intercepted by the separation device 100, and the cleaner air flow flows out of the first accommodating space 110a through the first outlet 102.

[0119] The separation device 100 is generally cylindrical. The base 200 has a general shape with a lower front and a higher rear. Here, "front" refers to the direction close to the first inlet 101, and "rear" refers to the direction away from the first inlet 101.

[0120] The separator 100 is tilted and mounted on the base 200. For canister vacuum cleaners, the base 200 has an extension 206 at the front that protrudes beyond the separator 100. When the cleaning device encounters an external force from the front, the extension 206 can contact the external force before the separator 100, buffering the force and reducing damage to the separator 100, thus protecting the separator 100.

[0121] Figure 1 and Figure 12 In the illustrated embodiment, the base 200 has protruding portions protruding from the separating device 100 on all sides of the separating device 100 , so that the base 200 can play a protective role on all sides of the separating device 100 , further ensuring the safety of the separating device 100 .

[0122] The driving member 300 includes a motor. In the embodiment shown in the present disclosure, the cyclone separation assembly 120 and the dust bag separation assembly 140 are both detachably connected to the first storage space 110a, so that either the cyclone separation assembly 120 or the dust bag separation assembly 140 can be used alone, or both can be used simultaneously. Based on this, the separation device 100 has at least two of the following usage modes: a first usage mode, a second usage mode, and a third usage mode. Specifically, when the separation device 100 is in the first usage mode, the cyclone separation assembly 120 is connected to the first storage space 110a; when the separation device 100 is in the second usage mode, the dust bag separation assembly 140 is connected to the first storage space 110a; and when the separation device 100 is in the third usage mode, both the cyclone separation assembly 120 and the dust bag separation assembly 140 are connected to the first storage space 110a.

[0123] In some optional embodiments, the dust bag separation assembly 140 can be detachably connected to the first storage space 110a, while the cyclone separation assembly 120 is fixed in the first storage space 110a and cannot be removed. In this embodiment, after the dust bag separation assembly 140 is removed, the cleaning device can have a first usage mode. After the dust bag separation assembly 140 is installed, the cleaning device has a third usage mode. In other words, in this embodiment, the cleaning device has a first usage mode and a third usage mode.

[0124] In the first usage mode, the cyclone separation assembly 120 can be reused, which can effectively reduce usage costs.

[0125] In the second and third modes of use, the detachable dust bag separator assembly 140 satisfies the requirements for large-capacity garbage storage and convenient cleaning. Furthermore, the third mode of use utilizes both the cyclone separator assembly 120 and the dust bag separator assembly 140 to separate fluids, thereby enhancing the fluid separation effect and improving the utilization of the first storage space 110a.

[0126] In summary, in the cleaning device of the present embodiment, the first accommodation space 110a is a shared space for the cyclone separation assembly 120 and the dust bag separation assembly 140. The cleaning device provides users with multiple usage modes, enabling a single cleaning device to simultaneously utilize the advantages of both separation devices 100, the dust bag separation assembly 140 and the cyclone separation assembly 120, thereby enriching the use scenarios of the cleaning device and improving the user experience.

[0127] In addition, the frequency of the first usage mode can be selected as needed. The higher the frequency of the first usage mode, the more conducive it is to reducing the consumption of the dust bag, thereby reducing the usage cost.

[0128] Optionally, the dust cup 110, the cyclone separation assembly 120 and the dust bag separation assembly 140 are approximately coaxially distributed.

[0129] like Figure 6a As shown, the axis of the central portion 125 is roughly coincident with the axis of the dust cup 110 (referring to coincidence or nearly coincidence); and / or, the axis of the first inlet 101 is roughly parallel to the axis of the dust cup 110 (referring to parallel or nearly parallel).

[0130] The axis of the central portion 125 roughly coincides with the axis of the dust cup 110 , thereby reducing fluid flow losses in the first accommodating space 110 a and the cyclone cup 121 and improving cleaning efficiency.

[0131] The axis of the first inlet 101 is roughly parallel to the axis of the dust cup and is closer to the base 200. This structure allows the groove 109 in front of the first inlet 101 to fit with the protrusion 205 of the base 200 exactly on the axis of the dust cup 112, making the fit more secure. In addition, the airflow entering from the first inlet 101 is more likely to flow toward the spiral surface 1226.

[0132] like Figure 3 and Figure 6b As shown, the first inlet 101 is located at the lower end surface of the dust cup 110 .

[0133] In order to obtain tangential acceleration, the first inlet is generally set on the side of the dust cup 110. Since an additional connecting pipe is required to connect the first inlet and the external space, if the first inlet is set on the side of the dust cup 110, the length of the connecting pipe will be longer, the fluid flow rate loss will be larger, and the structure will be complicated. In the embodiment of the present disclosure, the first inlet 101 is located at the lower end surface of the dust cup 110, which can at least shorten the length of the connecting pipe from the lower end surface to the side of the dust cup 110. The shortening of the connecting pipe can reduce the fluid flow rate loss. Figures 2 to 4b As shown, the dust cup 110 is generally cylindrical with a generally cylindrical sidewall. The dust cup 110 is mounted on the base 200 at an angle, with the sides and ends (the bottom end is shown) of the dust cup 110 in contact with the base 200. This tilt allows the lower end surface of the dust cup 110 to be less obstructed by the base 200, making it easier to dispose the first inlet 101 on the lower end surface of the dust cup 110 and facilitating the installation of the connecting pipe.

[0134] like Figure 3 As shown, the cleaning device further includes a suction port connector 103 and a main suction pipe 104. One end of the suction port connector 103 is connected to the first inlet 101, and the other end of the suction port connector 103 is used to connect to the main suction pipe 104. In actual application, a hose with a suction head can be connected to the inlet of the main suction pipe 104 to use the suction head to suck dirt from the external space.

[0135] Combine Figure 1The suction port connector 103 is located at the extension portion 206 in front of the base 200, which is one of the differences between the horizontal vacuum cleaner and the handheld vacuum cleaner below. In this way, the fluid can enter the dust cup 110 directly through the first inlet 101 via the extension portion 206.

[0136] Under the suction force provided by the driving member 300 , the air flow mixed with dust, garbage particles or debris enters the suction port connector 103 from the suction head, the hose, and the main suction pipe 104 in sequence, and then enters the dust cup 110 through the first inlet 101 .

[0137] Relatively speaking, heavier components such as the motor and reel are arranged at the rear of the base 200. This arrangement can make the front of the entire cleaning device small and light. When the user attaches a hose at the first entrance 101, the user can drag the cleaning device through the hose, and the cleaning device can more easily cross steps, obstacles, etc.

[0138] For example, the main suction pipe 104, the suction port connector 103, the hose and the suction head can together form a connecting pipe connecting the first inlet 101 and the external space. Figure 3 It can be seen that the suction port connector 103 is a curved pipe, and setting the first inlet 101 on the lower end surface of the dust cup 110 can at least shorten the length of the suction port connector 103.

[0139] Figure 3 In the embodiment shown, the suction port connector 103 is mounted on the machine base 200. The main suction pipe 104 and the suction port connector 103 are located in front of the machine base 200, away from the motor, and the suction port connector 103 is located at a position for connecting a hose.

[0140] Since the base 200 is heavier than the separator 100, placing the main suction pipe 104 and the suction port connector 103 on the base 200 is better than placing them on the dust cup lower cover 112. This makes the entire device more stable when the user drags the hose. Furthermore, when the separator 100 needs to be disassembled, the main suction pipe 104 and the suction port connector 103 do not need to be carried, making it easier to remove the separator 100.

[0141] The main suction pipe 104 and the suction port connector 103 are set at the bottom of the dust cup 110. After the fluid enters the suction port connector 103, it passes through the dust cup 110 and then passes through the motor. The direction of fluid flow is consistent with the internal fluid channel setting of the cleaning equipment, ensuring the shortest path of the fluid, reducing fluid loss and improving the efficiency of the cleaning equipment.

[0142] like Figure 2 As shown, the housing of the base 200 forms a recessed mounting chamber 201. Figure 1 As shown, a portion of the separation device 100 is located in the installation chamber 201 , and another portion is exposed outside the installation chamber 201 .

[0143] In the embodiment shown in the present disclosure, the separation device 100 and the base 200 are detachably connected. When the separation device 100 needs to be cleaned of dust, or the cyclone separation assembly 120 and the dust bag separation assembly 140 need to be switched, the separation device 100 can be removed from the base 200.

[0144] The detachable connection between the base 200 and the separation device 100 can be a snap connection. Figure 2 As shown, the base 200 has a hook 202, and the separation device 100 has a slot 108 (see Figure 15 After the separation device 100 is placed on the base 200, the hook 202 is inserted into the slot 108 to connect the base 200 and the separation device 100. It is understood that the detachable connection between the base 200 and the separation device 100 can also be a magnetic connection, a screw connection, an adhesive connection, etc.

[0145] In addition, if Figure 2 As shown, the base 200 also has a protrusion, such as Figure 6a As shown, the bottom of the separation device 100 also has a groove 109, and the shape of the groove 109 matches the protrusion 205. When the separation device 100 is connected to the base 200, the separation device 100 approaches the base 200 roughly in the vertical direction. After the position of the groove 109 at the bottom of the separation device 100 contacts the base 200, the separation device 100 is rotated with the protrusion 205 as the axis, and the rotation direction is the inclined direction toward the installation chamber 201 in the base 200, and then the protrusion 205 is stuck in the groove 205.

[0146] Without limitation, at the position where the base 200 and the separating device 100 are connected, the latching slot 108 and the groove 205 are located at opposite ends of the separating device 100 .

[0147] like Figure 2 As shown, the first inlet 101 and the first outlet 102 are both located between the hook 202 and the protrusion. In other words, the protrusion 205, the first inlet 101, the first outlet 102, and the hook 202 are arranged in this order, with the hook 202 adjacent to the outside of the first outlet 101 and the protrusion 205 adjacent to the outside of the first inlet 101. In this way, the first outlet 101 and the first inlet 101 are not easily leaked at the connection between the separation device 100 and the base 200, preventing the seal at the connection between the separation device 100 and the base 200 from failing during use.

[0148] like Figures 3 to 4b As shown, the dust cup 110 includes: a dust cup body 111 and a dust cup lower cover 112. The dust cup body 111 is a hollow part with an open lower end; the dust cup lower cover 112 is pivotally connected to the dust cup body 111.

[0149] In an embodiment not shown in the present disclosure, the dust cup lower cover 112 can also be detachably connected to the dust cup body 111, wherein after the dust cup lower cover 112 is disassembled, it can be completely separated from the dust cup body 111. The connection method of the dust cup lower cover 112 and the dust cup body 111 is not limited to this.

[0150] like Figure 4a and Figure 4b As shown, the dust cup lower cover 112 can open the lower end opening of the dust cup body 111. Figure 3 As shown, the dust cup lower cover 112 can also close the lower end opening of the dust cup body 111 to form a first accommodating space 110a together with the dust cup body 111.

[0151] The first inlet 101 passes through the dust cup lower cover 112 .

[0152] When the dust cup lower cover 112 is in the open state, the first accommodating space 110a is connected to the external space. The dust bag separation assembly 140 and the cyclone separation assembly 120 can be switched through the lower end opening of the dust cup body 111, and the garbage in the first accommodating space 110a can also be processed through the lower end opening of the dust cup body 111.

[0153] In the embodiment shown in the present disclosure, when the cyclone separation assembly 120 and the dust bag separation assembly 140 are separated from the dust cup 110, the separation direction is: along the axis of the dust cup 110 toward the first inlet 101. Figure 4a and Figure 4b As shown, when the cyclone separation assembly 120 and the dust bag separation assembly 140 need to be disassembled, the dust cup lower cover 112 is opened, and after the dust cup 110 releases the restraint of the dust bag separation assembly 140 and the cyclone separation assembly 120 (if any), the dust bag separation assembly 140 and the cyclone separation assembly 120 are removed along the axial direction of the dust cup 110 toward the first inlet 101.

[0154] In the prior art, the cyclone separation assembly is removed from the top of the dust cup, and the dust bag is removed along the vertical direction of the first inlet, and the two disassembly directions are different. In the embodiment of the present disclosure, the dust bag separation assembly 140 and the cyclone separation assembly 120 are both removed along the axial direction of the dust cup 110 toward the first inlet 101, ensuring that the two can share the same dust cup 110.

[0155] like Figure 3 As shown, the separation device 100 further includes a first filter element 130 , which is used to filter the fluid flowing from the cyclone separation assembly 120 and / or the dust bag separation assembly 140 to the first outlet 102 .

[0156] If the cleaning device is in the first usage mode, the first filter element 130 filters the fluid flowing out of the cyclone separation assembly 120. If the cleaning device is in the second usage mode, the first filter element 130 filters the fluid flowing out of the dust bag separation assembly 140. If the cleaning device is in the third usage mode, the first filter element 130 filters the fluid flowing out of both the dust bag separation assembly 140 and the cyclone separation assembly 120.

[0157] The first filter element 130 is a filter cotton. In addition, the first filter element 130 can also be Hepa, but is not limited thereto.

[0158] In the disclosed embodiment, the first filter element 130 has a higher filtration rating than the dust bag separator assembly 140, which in turn has a higher filtration rating than the cyclone separator assembly 120. The filtration rating is determined based on the minimum diameter of the dust that can be filtered. The smaller the minimum diameter of the dust that can be filtered, the higher the filtration rating; vice versa. Typically, the filtration rating of the dust bag separator assembly 140 is higher than that of the cyclone separator assembly 120 and can meet the user's daily needs. Specifically, particles in the fluid filtered by the dust bag separator assembly 140 will not damage the internal structure of the motor. Therefore, the first filter element 130 is only used in the first mode of use (i.e., only when the cyclone separator assembly 120 is used alone). Therefore, the first filter element 130 can be integrated with the cyclone separator assembly 120. When the cyclone separator assembly 120 is removed and replaced with the dust bag separator assembly 140, the first filter element 130 is also removed. This configuration reduces fluid loss in the second mode of use and also extends the life of the first filter element 102.

[0159] The dust cup body 111 is roughly cylindrical, and the upper end of the dust cup body 111 can be closed. Alternatively, the upper end of the dust cup body 111 also has an opening. Figure 3 As shown, the dust cup 110 further includes: a dust cup upper cover 113 , which is pivotally connected to the dust cup body 111 so as to be able to open or close the upper end opening of the dust cup body 111 .

[0160] like Figure 3 As shown, the first filter element 130 is located below the dust cup cover 113 and downstream of the cyclone separation assembly 120 and / or the dust bag separation assembly 140 in the fluid flow direction. When the dust cup cover 113 is in the open state, the first filter element 130 can be easily replaced.

[0161] like Figure 3 As shown, the cyclone separation assembly 120 has a second inlet 1201 for fluid to enter the interior thereof, a second outlet 1202 for fluid to flow out of the interior thereof, and an ash outlet 1211 (see Figure 5e), the second inlet 1201 is connected to the first inlet 101, the second outlet 1202 is connected to the first outlet 102, and the ash removal port 1211 is connected to the first accommodating space 110a.

[0162] The second inlet 1201 is approximately coaxial with the first inlet 101. Fluid passing through the first inlet 101 enters the second inlet 1201 and then enters the interior of the cyclonic separation assembly 120. After separation within the cyclonic separation assembly 120, the cleaner fluid flows from the second outlet 1202 to the first outlet 102, while the dirtier airflow, containing a larger amount of dust, garbage particles, or debris, flows out through the dust outlet 1211. Ultimately, the dust, garbage particles, or debris, and other solid contaminants, fall under the action of gravity to the bottom of the first storage space 110a (i.e., the dust cup lower cover 112). Opening the dust cup lower cover 112 allows these solid contaminants to fall out.

[0163] Therefore, combined with the pivotal connection between the dust cup lower cover 112 and the dust cup body 111, and the connection between the dust outlet 1211 of the cyclone separation assembly 120 and the first accommodating space 110a, garbage can be dumped conveniently.

[0164] like Figure 5a and Figure 5b As shown, the cyclone separation assembly 120 includes a cyclone cup 121 and a cyclone support 122. The cyclone support 122 is located in the cyclone cup 121, and the second inlet 1201 is used to allow fluid to enter the cyclone cup 121. The cyclone support 122 has a spiral surface 1226 extending from the second inlet 1201 to the second outlet 1202 around the axis of the cyclone support 122.

[0165] Combine Figure 5a and Figure 5b As shown, the ash outlet 1211 is located on the side of the cyclone cup 121 , and the second outlet 1202 is located above the ash outlet 1211 .

[0166] like Figure 5d and Figure 5e As shown, the spiral surface 1226 can be used to guide the fluid to flow upward in a spiral manner along the axis, provide tangential acceleration for the fluid, form eddy currents, and ensure the separation of the fluid. During the upward spiral of the fluid, the heavier fluid containing more dust, garbage particles or debris is thrown toward the ash outlet 1211 under the action of centrifugal force, and enters the first space through the ash outlet 1211. The lighter fluid with less dust content will continue to flow upward and flow out of the cyclone cup 121 through the second outlet 1202. In other words, during the upward spiral flow of the fluid entering the cyclone cup 121 through the second inlet 1201 along the spiral surface 1226, the purpose of intercepting solid dirt and separating dust and gas is achieved.

[0167] By providing the spiral surface 1226 and utilizing the characteristic that the spiral surface 1226 spirally rises in the axial direction, air intake at the bottom of the dust cup 110 is achieved, replacing the solution of air intake at the side of the dust cup 110.

[0168] like Figure 5e and Figure 5f As shown, the inner wall of the ash ejection port 1211 (referring to the side wall of the cyclone cup 121 that forms the ash ejection port 1211) has an air guide surface 1212 that is tangential to the inner wall of the cyclone cup 121. Under the centrifugal force of the vortex fluid, the heavier fluid carrying more solid dirt rises to the ash ejection port 1211. Under the action of the centrifugal force, the solid dirt is ejected along a path that is roughly tangential to the inner wall of the cyclone cup 121, consistent with the inclination of the air guide surface 1212. Therefore, the air guide surface 1212 can more smoothly eject the solid dirt from the dust cup.

[0169] The inner wall of the ash outlet 1211 at least partially protrudes out of the cyclone cup 121 , which can not only play a better role in guiding the flow, but also prevent the fluid flowing out of the cyclone cup 121 from flowing back into the cyclone cup 121 .

[0170] like Figure 5a 、 Figure 5b and Figure 5d As shown, the cyclone bracket 122 also has an air inlet joint 1221 extending along the axis direction of the cyclone bracket 122 ; in the fluid flow direction, the air inlet joint 1221 is located upstream of the spiral surface 1226 , and the inlet of the air inlet joint 1221 is the second inlet 1201 .

[0171] The air inlet connector 1221 extends toward the first inlet 101 so as to better connect the first inlet 101 and the internal space of the dust cup 110 .

[0172] like Figure 5d As shown, the turning point where the air inlet connector 1221 and the spiral surface 1226 meet has a transition slope 1203 that guides the airflow to smoothly transition to the spiral surface 1226 .

[0173] The air inlet joint 1221 is arranged axially along the cyclone cup bracket 122, the fluid inlet of the spiral surface 1226 is roughly tangent to the radial direction of the cyclone cup bracket 122, and the transition slope 1203 is roughly tangently connected to the air inlet joint 1221 and the spiral surface 1226 respectively.

[0174] The transition bevel 1203 can smoothly transition the junction between the air inlet joint 1221 and the spiral surface 1226, so that the fluid can smoothly transition at the turning point. Therefore, the transition bevel 1203 can reduce the energy loss of the fluid rushing into the cyclone bracket 122.

[0175] like Figure 5dAs shown, the cyclone bracket 122 includes: a central part 125 and a spiral blade 1225, the central part 125 is a hollow part with a filter hole 1222; the second outlet 1202 is located in the central part 125 and is located downstream of the filter hole 1222 along the fluid flow direction; the spiral blade 1225 extends spirally along the axial direction of the central part 125, and the spiral surface 1226 is the surface of the spiral blade 1225; the filter hole 1222 is located downstream of the spiral blade 1225 along the fluid flow direction.

[0176] like Figure 5e As shown by the middle arrow, after the mixed fluid enters the second inlet 1201, it climbs along the spiral surface 1226 of the spiral blade 1225. The spiral surface 1226 causes the gas to produce an upward circular motion. Figure 6b As shown by the middle arrow, the pressure in the center portion 125 is relatively low due to the suction force provided by the driving member 300. The fluid containing less solid dirt will pass through the filter holes 1222 and be sucked into the center portion 125, and finally flow out of the cyclone separation assembly 120 through the second outlet 1202. Figure 6b It can be seen that small particles of dirt in the relatively clean fluid can be absorbed by the first filter element 130 to further purify the fluid flowing to the driving element 300 and reduce the impact of dirt on the driving element 300.

[0177] During the upward flow of the fluid, Figure 6a As shown by the middle arrow, the density of dust and garbage particles is relatively high. Under the action of centrifugal force, they will gradually be thrown to the periphery. After climbing a few times along the inner wall of the cyclone, they will be thrown out of the cyclone cup 121 at the ash outlet 1211 and enter the space between the cyclone cup 121 and the dust cup 110 (i.e., part of the first accommodation space 110a). The air flow speed between the cyclone cup 121 and the dust cup 110 is relatively low. The garbage thrown out of the ash outlet 1211 will rotate around the outside of the cyclone cup 121 under the action of inertia and gradually settle to the bottom of the dust cup 110 under the action of gravity.

[0178] Garbage with a density close to that of air and a volume larger than the diameter of the filter holes 1222 will be blocked outside the central portion 125 where the filter holes 1222 are located, and will be continuously impacted by the subsequent fluid passing through and carried out of the dust removal outlet 1211.

[0179] like Figure 5d As shown, the central portion 125 is generally cylindrical. The spiral surface 1226 extends from the outer periphery of the central portion 125 toward the inner wall of the cyclone cup 121, so that there is no gap, or almost no gap, between the spiral blade 1225 and the cyclone cup 121. This structure allows the spiral surface 1226 to occupy a larger space between the central portion 125 and the cyclone cup 121, thereby maximizing the amount of vortex flow in the fluid entering the cyclone cup 121.

[0180] like Figure 5dAs shown, the air inlet joint 1221 is attached to the bottom of the spiral blade 1225 and is eccentrically arranged with respect to the central portion 125 .

[0181] The spiral blade 1225 is located below the filter hole 1222 and above the air inlet connector 1221 .

[0182] Generally, the filter holes 1222 are prone to residue, and the filter holes 122 are dirtier than the air inlet connector 1221. Furthermore, by placing the filter holes 1222 above the air inlet connector 1221, the user can pinch or hold the cleaner air inlet connector 1221 without touching the dirtier filter holes 1222, thereby improving the user experience.

[0183] The center portion 125 is closed at the bottom and open at the top (ie, the second outlet 1202 ) to ensure that the fluid entering the center portion 125 through the filter holes 1222 continues to flow upward.

[0184] like Figure 7a As shown, the diameter L3 of the center portion 125 is between 1 / 3 and 3 / 5 of the inner diameter L5 of the cyclone cup 121. This arrangement ensures better separation of heavier contaminants such as dust from the fluid. In the embodiment shown in this disclosure, L3 is 27 mm and L5 is 90 mm. For example, the inner diameter of the center portion 125 can be 1 / 3, 3 / 5, or 7 / 15 of the inner diameter of the cyclone cup.

[0185] The height L1 of the entire spiral surface 1226 (i.e., the height of the spiral blade 1225) is greater than or equal to the distance L2 from the top of the spiral blade 1225 to the dust outlet 1211. In the embodiment shown in the present disclosure, L1 is 60 mm and L2 is 55 mm, so as to ensure that the dust has sufficient force to rise.

[0186] Figure 5d The example shows spiral blades 1225 rotating less than two full revolutions, which reduces pressure drop and makes the cyclonic separation structure more compact. One full revolution refers to a 360-degree rotation of spiral blade 1225 around central portion 125. A spiral channel 124 is formed between the lower spiral blade 1225 and the upper spiral blade 1225. A transition slope 1203 connects the upper spiral blade 1225 to the air inlet connector 1221.

[0187] like Figure 5b As shown, the cyclone cup 121 and the cyclone bracket 122 are detachably connected. In the cyclone separation assembly 120, fluid flows between the cyclone cup 121 and the cyclone bracket 122 to achieve dust and gas separation. Dirt easily remains between the cyclone cup 121 and the cyclone bracket 122. The detachable cyclone cup 121 and the cyclone bracket 122 make it easier to clean each separately.

[0188] like Figure 5c As shown, the bottom end of the cyclone bracket 122 has a positioning notch 1223, as shown in FIG. Figure 5b As shown, the bottom end of the cyclone cup 121 has a positioning protrusion 1213 , which is downward along the axial direction and can be inserted into the positioning notch 1223 .

[0189] It is understood that the positioning notch 1223 can also be provided at the bottom end of the cyclone cup 121, and the positioning protrusion 1213 can be provided at the bottom end of the cyclone bracket 122. Alternatively, the cyclone cup 121 and the cyclone bracket 122 can both have positioning notches 1223 and positioning protrusions 1213, with the positioning protrusions 1213 corresponding to the positioning notches 1223. When the cyclone cup 121 and the cyclone bracket 122 are assembled, the corresponding positioning protrusions 1213 are inserted into the corresponding positioning notches 1223.

[0190] The cooperation between the positioning protrusion 1213 and the positioning notch 1223 can limit the relative rotation between the cyclone bracket 122 and the cyclone cup 121, thereby ensuring the reliability of the connection between the two.

[0191] like Figure 5c As shown, the bottom end of the cyclone bracket 122 has a flange 1224 protruding toward the outside of the cyclone bracket 122, and the flange 1224 has a positioning notch 1223. Figure 5a , the bottom end of the cyclone cup 121 abuts against the flange 1224 .

[0192] Combine Figure 5c and Figure 7f A mounting groove 127 is formed outside the side wall of the cyclone bracket 122 and above the flange 1224 , wherein the flange 1224 forms the bottom wall of the mounting groove 127 . The mounting groove 127 is used to accommodate the second sealing member 170 .

[0193] The cyclone cup 121 is a generally cylindrical structure with an opening at the bottom. When the cyclone bracket 122 is installed into the cyclone cup 121 through the bottom opening of the cyclone cup 121 , the contact between the flange 1224 and the cyclone cup 121 can remind both to be installed in place.

[0194] Without limitation, the cyclone cup 121 and the cyclone bracket 122 may be fixed together by utilizing friction or compression at the joint of the cyclone cup 121 and the cyclone bracket 122 .

[0195] The flange 1224 is roughly located at the periphery of the spiral blade 1225 at the bottom. When the cyclone bracket 122 needs to be disassembled, the bottom edge of the cyclone bracket 122 can be pinched by hand (for example, pinching the air inlet connector 1221), and the cyclone bracket 122 can be disassembled by hand (for example, pinching the air inlet connector 1221). Figure 5b ), separate the cyclone bracket 122 from the cyclone cup 121.

[0196] like Figure 5aAs shown, the cyclone separation assembly 120 further includes a cyclone cover plate 123. The cyclone cover plate 123 is located at the top of the cyclone cup 121, covers the gap between the cyclone cup 121 and the cyclone bracket 122, and is sealed to the cyclone cup 121 and the cyclone bracket 122 respectively.

[0197] The top of the cyclone cup 121 also has an opening, and the central portion 125 of the cyclone bracket 122 is substantially coaxial with the cyclone cup 121. The cyclone cover 123 covers the top opening of the cyclone cup 121 and has a through hole 1232 (such as Figure 5e The provision of the through hole 1232 can prevent the cyclone cover 123 from blocking the second outlet 1202 , thereby ensuring that the fluids in the cyclone cup 121 and the cyclone bracket 122 all flow out through the second outlet 1202 .

[0198] like Figure 7e As shown, the cyclone cover 123 has a lip 1231 extending to the inner wall of the second outlet 1202. The lip 1231 is sealed with the inner wall of the second outlet 1202. The lip 1231 can guide as much fluid as possible to the second outlet 1202 and outflow through the second outlet 1202, thereby limiting fluid leakage through the connection between the cyclone cover 123 and the central portion 125.

[0199] The lip 1231 overlaps the central portion 125 axially by at least 1-10 mm, and the inner and outer surfaces of the lip 1231 are smoothly transitioned at the junction. The thickness of the lip 1231 is between 0.2 and 0.7 times the thickness of the main wall. This minimizes fluid loss within the central portion 125 and allows airflow entering the central portion 125 through the filter holes 1222 to flow more efficiently into the second outlet 1202.

[0200] Exemplarily, the lip 1231 is 0.1 mm, 0.15 mm, or 0.5 mm thick in the axial direction and overlaps the central portion 125. The thickness of the lip 1231 is 0.2 mm, 0.3 mm, 0.25 mm, 1 mm, or 1.5 mm.

[0201] like Figure 7e As shown, the cyclone cover plate 123 is an arc transition at the corner from the longitudinal direction to the transverse direction, which can further reduce the flow velocity loss of the fluid. The cyclone cover plate 12 is connected to the central portion 125 in the longitudinal direction and to the side wall of the cyclone cup 121 in the transverse direction.

[0202] The cyclone cover plate 123 and the cyclone cup 121 are fixedly connected and cannot be disassembled. The two can be fixedly connected by ultrasonic welding. In addition, the cyclone cover plate 123 and the cyclone cup 121 can also be fixedly connected by screw connection, adhesive connection or other welding methods.

[0203] The cyclone cup 121 is detachably connected to the dust cup 110. When the cyclone cup 121 is connected to the dust cup 110, the connection between the cyclone separation assembly 120 and the dust cup 110 can be achieved; when the cyclone cup 121 is separated from the dust cup 110, the cyclone separation assembly 120 as a whole can be separated from the dust cup 110.

[0204] Optionally, the cyclone cup 121 may be directly connected to the dust cup 110 to achieve the detachability of the cyclone separation assembly 120 .

[0205] like Figure 7a and Figure 7b As shown, in the embodiment shown in the present disclosure, the cyclone cup 121 is indirectly connected to the dust cup 110 through the cyclone cup fixing frame 150. For example, the cleaning device further includes a cyclone cup fixing frame 150, the cyclone cup fixing frame 150 is located in the first accommodating space 110a, the cyclone cup fixing frame 150 has a first clamping portion, and the cyclone cup 121 has a second clamping portion. The first clamping portion is clamped with the second clamping portion to achieve a detachable connection between the cyclone cup 121 and the cyclone cup fixing frame 150.

[0206] like Figure 7c and Figure 7d As shown, the first engaging portion is a slot 151, and the second engaging portion is a protruding block 1214, which can be inserted into the slot 151. It is understandable that the first engaging portion can also be a block, and the second engaging portion can be a slot. Alternatively, the first engaging portion and the second engaging portion each include a block and a slot, and the slot and the block positions correspond one to one. When the cyclone cup fixing frame 150 and the cyclone cup 121 are connected, the block can be inserted into the corresponding slot.

[0207] like Figure 7c and Figure 7d As shown, the slot includes a first portion 152 extending axially along the cyclone cup 121 and having an opening, and a second portion 153 extending circumferentially along the cyclone cup 121, the second portion 153 being connected to the first portion 152. After the card is inserted into the first portion 152, it rotates circumferentially into the second portion 153 to connect the cyclone cup 121 to the cyclone cup fixing frame 150.

[0208] The first portion 152 and the second portion 153 of the card slot are substantially perpendicular to each other. The card block is substantially in the shape of a straight line. The number of the card slot and the card block can be independently set to one, two, three or more.

[0209] In the embodiment shown in the present disclosure, the cyclone cup fixing frame 150 is provided with three slots evenly spaced along the circumferential direction, and accordingly, the cyclone cup 121 has three blocks.

[0210] The cyclone separation assembly 120 can be installed in the dust cup 110 by rotating. Figure 4aRemove the cyclone separation assembly 120 from the dust cup 110 (as indicated by the arrow in the middle). The directions of rotation for removal and installation are opposite. During this process, the alignment of the positioning protrusion 1213 and the positioning notch 1223 also provides positioning for the engagement of the block and the slot. The larger positioning protrusion 1213 makes it easier to insert into the positioning notch 1223. Once the positioning protrusion 1213 is inserted into the positioning notch 1223, the corresponding block will also be inserted into the slot.

[0211] like Figure 7f As shown, the separation device 100 further includes a first sealing member 160 located within the first inlet 101. When the cyclone separation assembly 120 is installed in the dust cup 110, one end of the first sealing member 160 is sealedly connected to the bottom end of the cyclone bracket 122. When the dust bag separation assembly 140 is installed in the dust cup 110, one end of the first sealing member 160 is sealedly connected to the bottom end of the dust bag separation assembly 140. The other end of the first sealing member 160 is sealedly connected to the suction port connector 103.

[0212] In the upstream of the fluid flow, the first seal 160 seals with the suction port connector 103. In the downstream, the first seal 160 seals with the cyclone bracket 122 or the dust bag separation assembly 140. The sealing functions of both sides are set on the same seal, which improves the utilization rate of the first seal 160.

[0213] The first seal 160 is connected to the dust cup lower cover 112 and can be secured by closing the dust cup lower cover 112, tightly abutting the first seal 160 against the cyclone bracket 122 or the dust bag separation assembly 140 to achieve a seal at the upper end (i.e., the downstream side) of the first seal 160. After the separation device 100 is installed on the base 200, the gravity of the separation device 100 can also be used to tightly abut the first seal 160 against the suction port connector 103, thereby achieving a seal at the lower end (i.e., the upstream side) of the first seal 160. This sealing method of the first seal 160 can reduce the need for screws.

[0214] like Figure 7a and Figure 7f As shown, the first sealing member 160 is a substantially cylindrical sealing ring, which is substantially coaxial with the first inlet 101. The first sealing ring can be made of a soft material, such as silicone.

[0215] Figure 7f In the embodiment, the air inlet connector 1221 of the cyclone bracket 122 abuts against the first sealing member 160 to achieve a sealed connection.

[0216] refer to Figure 10bThe bottom end of the dust bag separation assembly 140 also has a dust bag connector 143. The dust bag connector 143 and the air inlet connector 1221 of the cyclone bracket 122 can be of the same specifications and can be used interchangeably. When the dust bag separation assembly 140 is installed in the dust cup 110, one end of the first sealing member 160 is sealedly connected to the dust bag connector 143.

[0217] In the embodiment of the present disclosure, the bottom of the separation assembly (referring to the cyclone separation assembly 120 and / or the dust bag separation assembly 140) is at least partially inserted into the dust cup lower cover 112. For example, the separation assembly can be inserted into the first inlet 101,

[0218] Combine Figure 7a and Figure 7f As shown, the first sealing member 160 includes a sealing body 161 and sealing lips 162 respectively located at the upper and lower ends of the sealing body 161. The sealing body 161 is connected to the dust cup lower cover 112 to achieve the fixation of the first sealing member 160.

[0219] The sealing lip 162 extends outward from the first inlet 101, and the bottom ends of the suction port connector 103 and the cyclone bracket 122 are sealed with the corresponding sealing lip 162. The first sealing member 160 is sealed with the separation device 100 and the suction port connector 103 respectively through the sealing lip 162. For example: Figure 7f As shown, the sealing body 161 can be clamped between two components in the dust cup lower cover 112 to fix the first sealing member 160.

[0220] The first sealing member 160 is a symmetrical member, that is, the sealing lips 162 are symmetrically distributed on the upper and lower sides of the sealing body 161. In this way, the upper and lower ends of the first sealing member 160 are non-directional, reducing the problem of inversion during assembly and facilitating installation.

[0221] like Figure 7f As shown, the shape of the sealing lip 162 is extended outward and upward from the sealing body 161, and the thickness gradually decreases outward and upward. The lower end surface of the cyclone cup bracket 122 contacts the upper surface of the sealing body 161. When the motor starts and fluid passes through the first sealing member 160, the top of the sealing lip 162 is the thinnest. Therefore, it is first affected by the vacuum and tends to become straight, so that the top of the sealing lip 162 can better seal with the end of the cyclone cup bracket 122 (i.e., the air inlet connector 1221).

[0222] In the axial direction, the inner surface of the fluid channel of the first seal 160 can be composed of two sealing lips 162 spliced ​​together, or the sealing body 161 can provide at least part of the fluid channel. The sealing body 161 providing the fluid channel can make the structure of the sealing lip 162 more stable, while also reducing the possibility of contact between the dust bag separation assembly 140 or the cyclone separation assembly 120 and the suction port connector 103.

[0223] The outer surface of the side of the first sealing member 160 is a roughly T-shaped structure, which facilitates the fixed installation of the first sealing member 160 and can also effectively ensure the axial positioning of the sealing lip 162.

[0224] like Figure 7f As shown, the cyclone separation assembly 120 further includes: a second sealing member 170 located between the bottom end of the cyclone cup 121 and the cyclone bracket 122 , and the second sealing member 170 is sealedly connected to the bottom end of the cyclone cup 121 and the cyclone bracket 122 respectively.

[0225] The second sealing member 170 can achieve sealing at the connection between the cyclone cup 121 and the bottom of the cyclone bracket 122 to reduce air leakage.

[0226] The second sealing member 170 may also be a soft rubber sealing ring.

[0227] It can be seen that in the cyclone separation assembly 120, the cyclone cup 121, the cyclone bracket 122, the cyclone cover 123 and the second seal 170 have no special waterproofing requirements. Therefore, the disassembled cyclone separation assembly 120 can be cleaned and dried, which further facilitates the cleaning of the cyclone separation assembly 120.

[0228] In the embodiment shown in this disclosure, no seal is provided on the top of the cyclone cup 121 due to the relatively low pressure differential and for ease of installation. In some embodiments not shown in this disclosure, a soft rubber seal may be provided on the top of the cyclone cup 121 to enhance the sealing of the cyclone separation assembly 120. For example, the seal may be located between the cyclone cup 121 and the cyclone cover plate 123, and sealed to both.

[0229] like Figure 7f As shown, after the cyclone bracket 122 is assembled with the dust cup 110, the elasticity of the first seal 160 allows the cyclone bracket 122 to have a movable distance along the axial direction of the first seal 160; the second seal 170 has an annular protrusion 171 protruding toward the cyclone cup 121, and the distance between the annular protrusion 171 and the bottom end of the cyclone cup 121 is greater than or equal to the movable distance.

[0230] The annular protrusion 171 can enhance the sealing performance of the second sealing member 170 .

[0231] The distance between the annular protrusion 171 and the bottom end of the cyclone cup 121 is greater than or equal to the movable distance, which can further ensure the sealing performance of the second sealing member 170 .

[0232] like Figure 7g and Figure 7jAs shown, according to some optional embodiments, the separation device 100 further includes: an anti-leakage assembly, which is movably connected to the dust cup 110, and the anti-leakage assembly has a first state and a second state.

[0233] In the embodiment shown in the present disclosure, when the anti-leaking assembly is in the first state, the anti-leaking assembly prevents the connection between different components of the dust cup 110 itself ( Figure 7i and Figure 7j ), when the anti-leaking assembly is in the second state, the anti-leaking assembly allows the connection between different parts of the dust cup 110 itself ( Figure 7g and Figure 7h ).

[0234] The different parts of the dust cup 110 itself include: a dust cup lower cover 112 and a dust cup main body 111, or a dust cup upper cover 113 and a dust cup main body 111.

[0235] In an embodiment not shown in the present disclosure, when the anti-leaking assembly is in a first state, the anti-leaking assembly hinders the connection between the dust cup 110 and the base 200; when the anti-leaking assembly is in a second state, the anti-leaking assembly allows the dust cup 110 to be connected to the base 200.

[0236] In the embodiments shown in the present disclosure, Figure 7i and Figure 7j As shown, when the anti-leakage assembly is in the first state, the anti-leakage assembly is partially located on the closing track of the dust cup lower cover 112 (approximately as shown in FIG. Figure 7g In the first state, the dust cup lower cover 112 cannot be covered on the dust cup main body 111 under the blocking effect of the anti-leakage assembly.

[0237] like Figure 7g and Figure 7h As shown, when the anti-leaking assembly is in the second state, the anti-leaking assembly is located outside the closing track of the dust cup lower cover 112, so as to allow the dust cup lower cover 112 to be connected to the dust cup body 111. At this time, the anti-leaking assembly does not have a blocking effect, and the dust cup lower cover 112 can cover the dust cup body 111.

[0238] When both the cyclone separator assembly 120 and the dust bag separator assembly 140 are removably installed in the dust cup, there is a risk of missing them. Using the anti-missing assembly prevents missing cyclone separator assembly 120 or dust bag separator assembly 140, ensuring that the separation assemblies can function properly in separating dust and gas. This also reduces the risk of excessive dirt entering the base 200 and damaging the drive element 300 due to missing cyclone separator assembly 120 or dust bag separator assembly 140.

[0239] When the cyclone separation assembly 120 or the dust bag separation assembly 140 is installed in the dust cup 110, the leak-proof assembly can be switched from the first state to the second state. Conversely, when the cyclone separation assembly 120 or the dust bag separation assembly 140 is removed from the dust cup 110, the leak-proof assembly can be switched from the second state to the first state.

[0240] Combine Figures 7h to 7k As shown, the anti-leakage assembly includes: a top rod 180 and an elastic member 182, the top rod 180 is connected to the dust cup lower cover 112; the elastic member 182 provides the top rod 180 with a first driving force toward the closing trajectory of the dust cup lower cover 112 (the direction of the first driving force is Figure 7k When the cyclone separation assembly 120 or the dust bag separation assembly 140 is assembled with the dust cup lower cover 112, the cyclone separation assembly 120 or the dust bag separation assembly 140 applies a second driving force opposite to the first driving force to the top rod 180, so that the anti-leakage assembly is in the second state.

[0241] When the top rod 180 is not subjected to external force, the elastic force of the elastic member 182 acts as a first driving force to drive the top rod 180 to be located in the closing track of the dust cup lower cover 112 to limit the connection between the dust cup lower cover 112 and the dust cup body 111.

[0242] After the cyclone separation assembly 120 or the dust bag separation assembly 140 is assembled with the dust cup lower cover 112, the cyclone separation assembly 120 or the dust bag separation assembly 140 applies an external force (i.e., a second driving force) to the push rod 180, pushing the push rod 180 to move the elastic member 182, thereby overcoming the first driving force of the elastic member 182. At this point, the push rod 180 is outside the closed trajectory, allowing the dust cup lower cover 112 to connect with the dust cup body 111. The elastic member 182 stores elastic deformation force.

[0243] After the cyclone separation assembly 120 or the dust bag separation assembly 140 is removed from the dust cup lower cover 112, the elastic member 182 recovers its deformation, generates a first driving force, and the anti-leakage assembly returns to the first state.

[0244] Figure 7k The elastic member 182 is exemplarily shown as a torsion spring. It is understandable that the elastic member 182 can also be other structures such as a compression spring, a tension spring or a spring sheet.

[0245] like Figure 7k and Figure 8 As shown, the top rod 180 is distributed around the first inlet 101, that is, the top rod 180 has an avoidance opening 181 that avoids the first inlet 101. The top rod 180 also has a first protrusion 1801 and a second protrusion 1802. The first protrusion 1801 has a guiding slope 1805 that guides the cyclone separation assembly 120 or the dust bag separation assembly 140 into the first inlet 101.

[0246] When the anti-leakage assembly is in the first state, Figure 7j As shown, the first protrusion 1801 is at least partially located in the first inlet 101, and the second protrusion 1802 is at least partially located in the closed track. The second protrusion 1802 will block the dust cup lower cover 112 during its closing process, that is, the second protrusion 1802 conflicts with the dust cup lower cover 112, and the dust cup lower cover 112 cannot be closed on the dust cup body 111; when the anti-leakage assembly is in the second state, the cyclone separation assembly 120 or the dust bag separation assembly 140 abuts against the first protrusion 1801, and the top rod 180 moves in the opposite direction (that is, along Figure 7k (in the opposite direction of the middle arrow) so that the first protrusion 1801 moves to the outside of the first entrance 101 and the second protrusion 1802 is located outside the closed track.

[0247] When the cyclone separator assembly 120 is installed in the dust cup 110, the air inlet connector 1221 is inserted into the avoidance opening 181 and contacts the guide slope 1805 of the first protrusion 1801. When the dust bag separator assembly 140 is installed in the dust cup 110, the dust bag connector 143 is inserted into the avoidance opening 181 and contacts the guide slope 1805 of the first protrusion 1801.

[0248] The guide slope 1805 guides the insertion of the cyclone separation assembly 120 or the dust bag separation assembly 140 , making the insertion smoother and facilitating the removal of the cyclone separation assembly 120 or the dust bag separation assembly 140 from the escape opening 181 .

[0249] like Figure 7j As shown, the anti-leakage assembly is located inside the dust cup lower cover 112, so that the impact of dust and other dirt on the anti-leakage assembly can be reduced. Figure 7i In the embodiment, the dust cup lower cover 112 further includes: a cover plate 183 , which covers the anti-leakage assembly, and the anti-leakage assembly is located in the interval space between the cover plate and the bottom wall of the dust cup lower cover 112 .

[0250] In the embodiment of the present disclosure, in the second usage mode, the dust is retained inside the dust bag separation assembly. In the first usage mode, the dust will be scattered on the dust cup lower cover 112 and the inner wall of the dust cup 110. The anti-leakage assembly is arranged inside the dust cup lower cover 112 instead of above the dust cup lower cover 112. The surface smoothness and flatness of the inner wall of the dust cup 110 and the dust cup lower cover 112 can be improved.

[0251] The gap between the cover plate 183 and the bottom wall of the dust cup lower cover 112 forms a space for the push rod 180 to move. The cover plate 183 has a limiting and protective effect on the push rod 180, limiting the entry of dirt between the cover plate 183 and the bottom wall of the dust cup lower cover 112 and affecting the movement of the push rod 180.

[0252] like Figures 7j to 8As shown, the anti-leakage assembly also includes: a third seal 1803 and a fourth seal 1804. The third seal 1803 is connected to the first protrusion 1801 to form a sealing structure at the movable position of the first protrusion 1801, thereby limiting dirt from blocking the movable path of the first protrusion 1801; the fourth seal 1804 is connected to the second protrusion 1802 to form a sealing structure at the movable position of the second protrusion 1802, thereby limiting dirt from blocking the movable path of the second protrusion 1802.

[0253] When the leak-proof assembly switches between the first and second states, the first and second protrusions 1801, 1802 frequently move in and out of the space between the cover plate 183 and the bottom wall of the dust cup lower cover 112. The third and fourth seals 1803, 1804 are provided to seal the movable positions of the two protrusions, further reducing the risk of dirt entering the space between the cover plate 183 and the bottom wall of the dust cup lower cover 112 and affecting the movement of the ejector pin 180.

[0254] like Figure 8 As shown, the third sealing member 1803 is a rubber-encapsulated structure formed on the first protrusion 1801 , and the fourth sealing member 1804 is a rubber-encapsulated structure formed on the second protrusion 1802 .

[0255] The rubber-coated structure has a better fixing effect on the ejector pin 180 and will not move during the movement of the ejector pin 180 , thereby better ensuring the sealing effect when the ejector pin 180 is in the moving state.

[0256] like Figure 9 As shown, the dust cup lower cover 112 includes a first cover 112a, a second cover 112b and a spring 184. The second cover 112b is located inside the first cover 112a. The first cover 112a forms part of the exterior panel of the dust cup lower cover 112. The first cover 112a has a third clamping portion 112c, and the dust cup has a fourth clamping portion 110b. After the dust cup lower cover 112 is covered with the dust cup 110, the fourth clamping portion 110b is clamped with the third clamping portion 112c. The spring 184 is located between the first cover 112a and the second cover 112b and provides a third driving force to drive the first cover 112a away from the dust cup 110. Figure 9 As shown, the third driving force is used to strengthen the engagement between the fourth engaging portion 110b and the third engaging portion 112c.

[0257] The use of the spring 184 can reduce the risk of the fourth clamping portion 110b and the third clamping portion 112c being separated, thereby ensuring the reliability of the connection between the dust cup lower cover 112 and the dust cup 110.

[0258] like Figure 9 As shown, the third clamping portion 112c and the fourth clamping portion 110b are both hooks.

[0259] like Figure 9As shown, the first cover 112 a and the second cover 112 b clamp the sealing body 161 of the first sealing member 160 therebetween to fix the first sealing member 160 .

[0260] like Figure 10a and Figure 10b The dust bag separation assembly 140 includes a dust bag 141 and a dust bag bracket 142. The dust bag bracket 142 has a third inlet 1204 (eg, Figure 10b As shown in FIG, the third inlet 1204 is located at the bottom end of the dust bag bracket 142 and can be docked with the first inlet 101.

[0261] The dust bag connector 143 is located at the bottom of the dust bag support 142 and extends toward the first inlet 101 . The two can be integral components. The inlet of the dust bag connector 143 is the third inlet 1204 .

[0262] The dust bag connector 143 extends from the dust bag bracket 143 toward the first inlet 101. Its shape is roughly cylindrical and fits the first inlet 101, and its size is slightly smaller than the inlet.

[0263] like Figure 10b As shown, a guide rib 1431 may be provided on the outside of the dust bag connector 143 .

[0264] The dust cup lower cover 112 partially protrudes toward the interior of the dust cup 110 around the first inlet 101, as shown in FIG. Figure 7i and Figure 7j As shown, the cover plate 183 is arched upward. This local protrusion can facilitate the installation of an anti-leakage device under the cover plate 183, and can also lengthen the installation guide length of the dust bag connector 143 and the dust cup lower cover 112.

[0265] In the embodiment of the present disclosure, at least a portion of the bottom of the separation component is inserted into the dust cup lower cover 112. The position inserted into the dust cup lower cover 112 can be a partially protruding portion thereof. This structure enables the dust cup lower cover 112 to have a certain "wrapping" effect on the separation component, reducing dust accumulation, thereby improving the cleanliness of the dust cup 110.

[0266] In the fluid flow direction, if the dust bag separation assembly 140 is installed in the dust cup 110, the dust bag connector 143 is at least partially inserted into the dust cup lower cover 112. If the cyclone separation assembly 120 is installed in the dust cup 110, the air inlet connector 1221 is at least partially inserted into the dust cup lower cover 112.

[0267] The bottom of the separation assembly includes a grip portion, which is used for disassembly and installation of the cyclone separation assembly 120 and the dust cup 110. Exemplarily, the portion of the separation assembly inserted into the dust cup lower cover 112 can be the grip portion.

[0268] The gripping portion is at least partially inserted into the first inlet 101; the gripping portion of the cyclone separation assembly 120 is the air inlet connector 1221, and the gripping portion of the dust bag separation assembly 140 is the dust bag connector 143. In summary, the air inlet connector and the dust bag connector 143 not only communicate with the first inlet 101, serving as a partial fluid passage, but also trigger the state switching of the anti-leakage assembly after insertion into the first inlet 101. Furthermore, they also serve as gripping portions, facilitating the removal and installation of the separation assembly, achieving multiple goals at once.

[0269] The part of the separation component at the bottom inserted into the dust cup lower cover 112 (for example: the air inlet connector 1221 or the dust bag connector 143) not only has a guiding function, but also can provide friction for the disassembly and installation of the cyclone separation component 120 and the dust cup 110. The user can install and disassemble the cyclone separation component 120 by rotating the grip part up and down, or the user can disassemble and install the cyclone cup 121 and the cyclone bracket 122 by holding the grip part.

[0270] like Figure 10a As shown, the dust bag connector 143 abuts the first sealing member 160 to achieve a sealed connection. The lower end surface of the dust bag connector 143 contacts the upper surface of the sealing body 161. When the motor is started and fluid flows through the first sealing member 160, the top of the sealing lip 162 is the thinnest part and is therefore the first to be affected by the vacuum, tending to straighten. This allows the top of the sealing lip 162 to better seal with the dust bag connector 143.

[0271] Without limitation, the other structures of the dust bag connector 143, and the relationship between the dust bag connector 143 and other structures in the dust cup 110, can be the same as the air inlet connector 1221 in the cyclone separation assembly 120. The third inlet 1204 and the second inlet 1201 are both connected to the same first inlet 101, so that the first inlet 101 can be adapted to the cyclone separation assembly 120 and the dust bag separation assembly 140 respectively, thereby improving the utilization rate of the first inlet 101.

[0272] like Figure 3 As shown, the cleaning device further includes: a driving member 300, the driving member 300 is used to provide suction force; Figure 11 As shown, the base 200 has a third outlet 203 for fluid to flow to the outside world, and a fluid channel connecting the first outlet 102 and the third outlet 203. The fluid channel is the flow channel of the fluid within the base 200. After the fluid flowing out of the separation device 100 enters the base 200, it eventually flows to the outside world through the third outlet 203.

[0273] Compared with the existing vacuum cleaner, the entire larger upper cover is rotated to open and take out the dust bag 141, such as Figure 4bAs shown, in the embodiment of the present disclosure, the dust bag 141 is replaced after the pivotally connected dust cup lower cover 112 is opened. After the dust cup lower cover 112 is closed, not only can the first sealing member 160 be compressed to achieve sealing at the first inlet 101, but also sealing members can be arranged around the dust cup lower cover 112 to achieve sealing at the connection between the dust cup lower cover 112 and the dust cup body 111. This makes the sealing method for ensuring vacuum degree simpler.

[0274] like Figure 10b As shown, the dust bag bracket 142 also has a notch 1401. Correspondingly, the dust cup body 111 has a protrusion corresponding to the notch, which can be inserted into the notch 1401 to ensure that the two are installed in place and ensure the stability of the connection between the dust bag separation assembly 140 and the dust cup.

[0275] like Figure 11 As shown, the base 200 includes: a shell and a cover 210 located in the shell, the cover 210 includes: an outer cover 220 and an inner cover 230, the outer cover 220 has a third accommodating space 204, and the third outlet 203 is connected to the third accommodating space 204; the inner cover 230 is located in the third accommodating space 204.

[0276] like Figure 13 As shown, the inner cover 230 includes: a bottom wall 231, an outer wall 232 and an inner wall 233, the inner wall 233 extends axially from the bottom wall 231 along the inner cover 230 to form an inner cavity 234, the outer wall 232 extends axially from the bottom wall 231 along the inner cover 230 to form an outer cavity 235, and the outer cavity 235 is located between the inner wall 233 and the outer wall 232; the driving member 300 is at least partially inserted into the inner cavity 234, and the outlet of the driving member 300 is located in the inner cavity 234; the inner wall 233 has a first through hole 2331 for fluid to flow from the inner cavity 234 to the outer cavity 235, and the outer wall has a second through hole 2321 for fluid to flow from the outer cavity 235 to between the outer cover 220 and the inner cover 230.

[0277] The outer cover 220 , the inner cover 230 and the driving member 300 jointly form a fluid channel.

[0278] like Figures 11 to 13 As shown, the fluid flowing out of the driving member 300 enters the inner cavity 234 of the inner cover 230, then enters the outer cavity 235 through the first through hole 2331, and then flows into the space between the inner cover 230 and the outer cover 220 (that is, part of the space of the third accommodating space 204) through the second through hole 2321, and finally flows from the outer cover 220 to the third outlet 203.

[0279] Among them, a high-density sponge is connected between the driving member 300 and the inner cover 230 to reduce noise. The driving member 300 and the inner cover 230 can form an upstream air duct together. After the fluid rushes out of the inner cover 230, it enters another air duct composed of the inner cover 230 and the outer cover 220. The airflow flows to Figures 11 to 13 shown.

[0280] like Figure 11 As shown, the outer cover 220 includes an upper cover 221 and a lower cover 222 covering the opening of the upper cover 221. The upper cover 221 and the lower cover 222 together form a third accommodating space 204 for accommodating the inner cover 230.

[0281] like Figure 14d As shown, the third outlet 203's airflow direction is roughly perpendicular to the motor (i.e., the drive member 300) axis and is located to the right of the motor. The third outlet 203's axis is perpendicular to the motor axis, making airflow more convenient. When using a cleaning device, users typically hold the hose in their right hand and stand to the left of the device. The right location of the third outlet 203 reduces the possibility of airflow blowing toward the user, improving the user experience.

[0282] The third outlet 203 includes a first sub-outlet 203a located on the housing, and a second sub-outlet 203b ( Figure 12 ), the first sub-outlet 203a is coaxial with the second sub-outlet 203b, and the fluid in the third accommodating space 204 first passes through the second sub-outlet 203b and then passes through the first sub-outlet 203a to flow to the external environment.

[0283] The high-speed fluid has a lower airflow velocity after bypassing the inner cover 230 and the outer cover 220 . Moreover, this structure has two more walls than the direct outlet structure where the fluid flows directly from the driving member 300 to the third outlet 203 . Both of these factors can reduce noise.

[0284] like Figure 13 As shown, the first through hole 2331 and the second through hole 2321 are distributed in opposite directions, which can extend the flow path of the fluid in the inner cover 230 and help further reduce the fluid velocity.

[0285] like Figure 12 As shown, the third outlet 203 is arranged opposite to the second through hole 2321. This can extend the flow path of the fluid between the inner cover 230 and the outer cover 220, which is conducive to further reducing the fluid velocity.

[0286] The cleaning device further includes a fifth seal and a sixth seal. The fifth seal is respectively sealedly connected to the driving member 300 and the inner wall to prevent fluid from flowing out of the inner cavity 234 through the connection between the driving member 300 and the inner wall. The sixth seal is respectively sealedly connected to the outer wall and the outer cover 220 to prevent fluid from flowing out of the outer cavity 235 through the connection between the outer wall and the outer cover 220.

[0287] like Figure 14a and Figure 14bAs shown, the cleaning device further includes: a second filter element 240 located in the third outlet 203 , and the outer side of the second filter element 240 facing away from the driving element 300 has an aromatherapy installation position.

[0288] The aromatherapy mounting area is used to install the aromatherapy device 250. Placing the aromatherapy mounting area near the third outlet 203 ensures that the cleaning device is immediately scented. Using the third outlet 203 to disperse the fragrance from the aromatherapy device 250 helps expand the fragrance's range and diffusion rate, making the scent more concentrated. The aromatherapy device 250 can mask any odors that may be present during cleaning, enhancing the user experience.

[0289] If the motor power is high, the motor has been operating for a long time, or the motor speed is high, the air flowing out of the third outlet 203 will be heated. This heated air will further accelerate the flow of fragrance when it passes through the aromatherapy installation area. The second filter element 240 is a HEPA filter, and the aromatherapy installation area is a mounting hole 241 formed on the HEPA external filter frame. Mounting hole 241 minimizes obstruction of the aromatherapy element 250, thereby allowing the aromatherapy element 250 to evaporate more effectively.

[0290] The HEPA is generally cylindrical in shape, with the second filter element 240 and the cylindrical cord reel 280 positioned on either side of the motor. This arrangement reduces the length of the cleaning device and concentrates the weight in one place, improving device stability and enhancing the user experience.

[0291] like Figure 14b As shown, the wall of the mounting hole 241 has a notch 242 for taking in and placing the fragrance component 250 .

[0292] The notch provides an operable position for the user to take and place the aromatherapy component 250. For example, two notches 242 can be symmetrically provided on both sides of the mounting hole 241. When taking and placing the aromatherapy component 250, two fingers can be placed in the corresponding notches 242 to hold the aromatherapy component, making it easier to take and place the aromatherapy component.

[0293] The aromatherapy element 250 can be a solid in the form of a sheet, a sphere, or a block, or a liquid soaked in a water-absorbing material. The aromatherapy element 250 can also be a semi-solid. The specific form of the aromatherapy element 250 is not intended to limit the present application.

[0294] Figures 14a to 14c A roughly annular aromatherapy element 250 is shown as an example. The annular aromatherapy element 250 can increase its contact area with the fluid, further improving the aromatherapy effect.

[0295] Figure 14c As can be seen in FIG, an air outlet cover 270 is further provided outside the fragrance member 250, and the fragrance member 250 is located between the second filter member 240 and the air outlet cover 270. The third outlet 203 is partially formed on the air outlet cover 270.

[0296] like Figure 14b As shown, the depth of the mounting hole 241 is greater than the thickness of the fragrance. This provides a certain degree of protection for the fragrance. For example, when the cleaning device is hit by an external object, the external object will first contact the wall of the mounting hole 241 and will not touch the fragrance.

[0297] like Figure 14b As shown, the hole wall of the mounting hole 241 has a limiting buckle 260 for limiting the fragrance component 250 in the mounting hole 241.

[0298] The limiting buckle 260 can better fix the aroma diffuser in the mounting hole 241, ensuring the reliability of the aroma diffuser fixation.

[0299] Taking the second filter element 240 as HEPA as an example, HEPA includes a frame located on the outside and an internal filter element 242 located inside the frame. The mounting hole 241 and the limiting buckle 260 are both located on the frame 241, and the fragrance is located between the limiting buckle 260 and the internal filter element 242.

[0300] The limiting buckle 260 has an inclined surface 261 for guiding the aromatherapy component 250 to be inserted into the mounting hole 241. The inclined surface 261 can better guide the aromatherapy component 250 to be inserted into the mounting hole 241.

[0301] The separation device 100 also includes: at least one of the following located on the dust cup 110: a dust cup release button 107a, a dust cup upper cover release button 105 and a dust cup lower cover release button 106.

[0302] Dust cup release button 107a. When the dust cup release button 107a is triggered, the dust cup 110 can be separated from the base 200 of the cleaning equipment, making it convenient to remove the separation device 100 from the base 200.

[0303] The dust cup cover release button 105, when the dust cup cover release button 105 is triggered, the dust cup cover 113 can be opened, and the first filter element 130 can be easily replaced.

[0304] The dust cup lower cover release button 106, when the dust cup lower cover release button 106 is triggered, the dust cup lower cover 112 can be opened, which can facilitate dumping of the garbage remaining in the dust cup 110.

[0305] Figure 15 It is exemplarily shown that the dust cup 110 is provided with a dust cup release button 107a, a dust cup upper cover release button 105 and a dust cup lower cover release button 106.

[0306] For example, Figure 14a and Figure 15As shown, the dust cup upper cover 113 has a first handle 107 , the dust cup release button 107a is located on the top of the first handle 107 , and the dust cup upper cover release button 105 and the dust cup lower cover release button 106 are both located on the side of the dust cup 110 .

[0307] Combine Figure 14b As shown, the dust cup lower cover release button 106 is located on the side of the dust cup facing the base 200, which can reduce the risk of the dust cup lower cover release button 106 being accidentally touched.

[0308] The third usage mode of the cleaning device in the embodiment of the present disclosure is described below.

[0309] Exemplarily, the dust bag separation assembly 140 has a second accommodation space; when the separation device 100 is in the third usage mode, the cyclone separation assembly 120 is at least partially located in the second accommodation space, and the dust bag separation assembly 140 filters fluid downstream of the cyclone separation assembly 120 .

[0310] In the third use mode, the dust outlet 1211 of the cyclone separation assembly 120 is connected to the inner space (ie, the second accommodation space) of the dust bag separation assembly 140. The dust bag can further filter the fluid separated by the cyclone separation assembly 120.

[0311] The dust bag separation assembly 140 can be seen in Figure 10b The structure of the dust bag assembly is shown. At the bottom of the dust bag separation assembly 140, the dust bag connector 143 can be larger than the air inlet connector, allowing the two to be nested. At the top of the dust bag separation assembly 140, the dust bag can be partially sandwiched between the cyclone cup 121 and the cyclone cup holder 150. Fluid flowing out of the second outlet 1202 of the cyclone holder 122 is filtered by the dust bag before flowing to the first filter element 130.

[0312] Figures 16 to 19 A structural diagram of a handheld vacuum cleaner is shown exemplarily.

[0313] and Figure 1 and Figure 2 The difference between the canister vacuum cleaner shown is that Figures 16 to 19 Only the end portion (the bottom end is shown in the figure) of the separating device 100 of the vacuum cleaner is in contact with the machine base 200. The machine base 200 is provided with a second handle 290 for the user to grasp.

[0314] Generally, the first suction port of a handheld vacuum cleaner (also equivalent to Figure 16 The main suction pipe 104 shown is not connected to a hose, but to a hard straw.

[0315] In the handheld vacuum cleaner, the suction port connector is installed at the bottom of the separation device 100. Figures 16 to 19 The suction port connector is not shown in the figure. Its structure can be referred to Figure 13Middle suction port connector 103.

[0316] like Figure 17 As shown, the dust cup lower cover 112 of the handheld vacuum cleaner is pivotally connected to the dust cup body 111. After the dust cup lower cover 112 is opened, the cyclone separation assembly 120 (such as Figure 18 As shown) and dust bag separation assembly 140 (as Figure 19 shown).

[0317] The other structures of the handheld vacuum cleaner may be the same as the corresponding structures of the horizontal vacuum cleaner, and will not be described again here.

[0318] The cleaning device of the embodiment of the present disclosure is not limited to a horizontal vacuum cleaner and a handheld vacuum cleaner, and may also be a barrel vacuum cleaner, an upright vacuum cleaner, etc.
