Description

Cleaning device TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning appliances, in particular to a cleaning device with multiple use modes. BACKGROUND

[0002] Cleaning devices can use suction flow to suck away fluid carrying stains, assisting manual cleaning work. Taking a vacuum cleaner as an example, the vacuum cleaner includes a separation device (also referred to as a filter), which is used to filter dirty fluid and store dust, large particles and other garbage left after filtration. A dust bag is a commonly used separation device for a vacuum cleaner. After the fluid enters the dust bag, dust or large particles are temporarily stored in the dust bag, and relatively clean fluid filtered out of the dust bag flows out of the dust bag through the air holes of the dust bag. The dust bag can store a large amount of garbage. When the amount of garbage stored in the dust bag reaches a certain amount, the dust bag can be directly discarded and replaced with a new dust bag, and the garbage is easy to clean. However, the dust bag needs to be replaced frequently as a disposable consumable, which is relatively expensive to use. SUMMARY

[0106] In the present disclosure, the terms "first" and "second" are only for the purpose of clear description, and cannot be understood as the relative importance of the indicated features or the number of indicated technical features. Therefore, the features defined with "first" and "second" can explicitly include at least one of the features. In the description of the present disclosure, the meaning of "multiple" is at least two, such as two, three, etc.; the meaning of "several" is at least one, such as one, two, three, etc.; except for explicit and specific limitations.

[0107] In the present disclosure, unless specifically defined otherwise, the terms "mount", "connect", "connection", "fixed", "set", and the like should be construed in a broad sense. For example, "connection" can be fixed connection, detachable connection, or integral; can be mechanical connection, electrical connection; can be direct connection, indirect connection through intermediate medium, or internal connection of two elements or interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0108] In the present disclosure, unless specifically defined otherwise, the first feature "on", "over", "above" and "top" of the second feature, "under", "below", "under" or "under" can be direct contact between the first feature and the second feature, or indirect contact between the first feature and the second feature through intermediate medium. Moreover, the first feature "over", "above" and "top" of the second feature can be directly above or obliquely above the first feature, or only indicate that the horizontal height of the first feature is higher than the horizontal height of the second feature. The first feature "under", "below" and "under" of the second feature can be directly below or obliquely below the first feature, or only indicate that the horizontal height of the first feature is less than the horizontal height of the second feature.

[0109] In the embodiments of the present disclosure, the cleaning device includes but is not limited to a vacuum cleaner, and the "fluid" is a mixed fluid, which can refer to an air flow mixed with dust, garbage particles or fragments.

[0110] Fig. 1 and Fig. 2 exemplarily show a schematic structural view of a horizontal vacuum cleaner.

[0111] As shown in Fig. 1 and Fig. 2, the cleaning device provided by the embodiments of the present disclosure includes a separation device 100 and a base 200 serving as a carrier for mounting the separation device 100. As shown in Fig. 3 to Fig. 4a, the separation device 100 includes a dust cup 110 and a separation assembly located in the dust cup 110, which includes at least one of a cyclone separation assembly 120 and a dust bag separation assembly 140 (shown in Fig. 4b). The dust cup 110 has a first containing space 110a, a first inlet 101 for fluid to enter the first containing space 110a, and a first outlet 102 for fluid to flow out of the first containing space 110a. Generally, the base 200 also serves as a mounting carrier for a driving member 300. The driving member 300 is used to provide a suction flow. After the suction flow enters the first containing space 110a from the external space through the first inlet 101, the dust, hair, large particle garbage and other solid dirt in the fluid are intercepted by the separation device 100, and the relatively clean air flow flows out of the first containing space 110a through the first outlet 102.

[0112] The separating device 100 is substantially cylindrical. The base 200 has a substantially shape of low in front and high in back. Here, "front" refers to the direction close to the first inlet 101, and "back" refers to the direction away from the first inlet 101.

[0113] The separating device 100 is obliquely arranged on the base 200. For a horizontal vacuum cleaner, the base 200 has an extension portion 206 protruding from the separating device 100 at the front. When the cleaning device encounters an external force impact at the front, the extension portion 206 can be in contact with the external force before the separating device 100, thereby buffering the external force and reducing the damage of the external force to the separating device 100, and protecting the separating device 100.

[0114] In the embodiment shown in FIG. 1 and FIG. 12, the base 200 has an extension portion protruding from the separating device 100 around the separating device 100, so that the base 200 can protect the separating device 100 around the separating device 100, further ensuring the safety of the separating device 100.

[0115] The driving member 300 includes a motor. In the embodiment shown in the disclosure, the cyclone separation assembly 120 and the dust bag separation assembly 140 are detachably connected in the first containing space 110a, so that one of the cyclone separation assembly 120 and the dust bag separation assembly 140 can be used alone, or the cyclone separation assembly 120 and the dust bag separation assembly 140 can be used simultaneously. Based on this, the separating device 100 has at least two of a first use mode, a second use mode and a third use mode. When the separating device 100 is in the first use mode, the cyclone separation assembly 120 is connected in the first containing space 110a; when the separating device 100 is in the second use mode, the dust bag separation assembly 140 is connected in the first containing space 110a; and when the separating device 100 is in the third use mode, the cyclone separation assembly 120 and the dust bag separation assembly 140 are both connected in the first containing space 110a.

[0116] In some optional embodiments, the dust bag separation assembly 140 can be detachably connected in the first containing space 110a, but the cyclone separation assembly 120 is fixed in the first containing space 110a and cannot be detached. In this embodiment, after the dust bag separation assembly 140 is detached, the cleaning device has the first use mode. After the dust bag separation assembly 140 is installed, the cleaning device has the third use mode. That is, in this embodiment, the cleaning device has the first use mode and the third use mode.

[0117] In the first use mode, the cyclone separation assembly 120 can be reused, which can effectively reduce the use cost.

[0118] In the second and third use modes, the dust bag separation assembly 140 is detachable, meeting the requirements of large-capacity storage of garbage and convenient cleaning. Moreover, the third use mode simultaneously utilizes the cyclone separation assembly 120 and the dust bag separation assembly 140 to separate the fluid, which can improve the separation effect of the fluid and improve the utilization rate of the first containing space 110a.

[0119] In summary, in the cleaning device of the embodiment of the present disclosure, the first containing space 110a is a shared space of the cyclone separation assembly 120 and the dust bag separation assembly 140. The cleaning device provides multiple use modes for users, realizes the advantages of both the dust bag separation assembly 140 and the cyclone separation assembly 120, enriches the use scenarios of the cleaning device, and improves the user experience.

[0120] In addition, the frequency of the first use mode can also be selected as needed. The higher the frequency of the first use mode, the more conducive to reducing the consumption of the dust bag, thereby reducing the use cost.

[0121] Optionally, the dust cup 110, the cyclone separation assembly 120, and the dust bag separation assembly 140 are coaxially distributed.

[0122] As shown in FIG. 6a, the axis of the central portion 125 is substantially coincident with the axis of the dust cup 110 (meaning coincident or close to coincident); and / or, the axis of the first inlet 101 is substantially parallel to the axis of the dust cup 110 (meaning parallel or close to parallel).

[0123] The axis of the central portion 125 is substantially coincident with the axis of the dust cup 110, which reduces the fluid flow loss in the first containing space 110a and the cyclone cup 121, and improves the cleaning efficiency.

[0124] The axis of the first inlet 101 is substantially parallel to the axis of the dust cup, and is closer to the direction of the base 200. This structure can make the groove 109 in front of the first inlet 101 cooperate with the protrusion 205 of the base 200 just at the axis position of the dust cup 112, so that the cooperation is more firm, and the airflow entering from the first inlet 101 is more likely to flow to the spiral surface 1226.

[0125] As shown in FIG. 3 and FIG. 6b, the first inlet 101 is located at the lower end surface of the dust cup 110.

[0126] To obtain the tangential acceleration, the first inlet is usually arranged at the side of the dust cup 110. If the first inlet is arranged at the side of the dust cup 110, the length of the communication pipeline connecting the first inlet and the external space is relatively long, the fluid flow rate loss is relatively large, and the structure is complex. 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 communication pipeline from the lower end surface of the dust cup 110 to the side of the dust cup 110. The shortening of the communication pipeline can reduce the fluid flow rate loss. As shown in FIGS. 2 to 4b, the dust cup 110 is generally cylindrical and has a generally cylindrical side wall. The dust cup 110 is obliquely installed on the base 200, and the side and end (the bottom end is shown in the figure) of the dust cup 110 are in contact with the base 200, respectively. After the inclination, the lower end surface of the dust cup 110 can be less blocked by the base 200, and the first inlet 101 can be more conveniently arranged at the lower end surface of the dust cup 110, and the installation of the communication pipeline is also more convenient.

[0127] As shown in FIG. 3, the cleaning device further comprises a suction connector 103 and a main suction pipe 104, one end of the suction connector 103 is connected with the first inlet 101, and the other end of the suction connector 103 is used to connect the main suction pipe 104. In actual application, a hose with a suction head can be connected at the inlet of the main suction pipe 104, so as to suck the dirt in the external space by the suction head.

[0128] In combination with FIG. 1, the suction connector 103 is located at the extension portion 206 in front of the base 200, which is one of the differences between the horizontal cleaner and the handheld cleaner below. In this way, the fluid can enter the dust cup 110 through the first inlet 101 directly through the extension portion 206.

[0129] The air flow mixed with dust, garbage particles or fragments enters the suction connector 103 from the suction head, the hose and the main suction pipe 104 in sequence under the action of the suction force provided by the driving member 300, and then enters the dust cup 110 through the first inlet 101.

[0130] Relatively, the relatively heavy components such as the motor and the winder are arranged at the rear of the base 200. Such arrangement can make the front of the entire cleaning device small and light. When the user attaches the hose at the first inlet 101, the cleaning device is more likely to pass over the steps, obstacles and the like when the user drags the cleaning device through the hose.

[0131] Exemplarily, the main suction pipe 104, the suction connector 103, the hose and the suction head can jointly form a communication pipeline connecting the first inlet 101 and the external space. As shown in FIG. 3, the suction connector 103 is a bend pipe, and the first inlet 101 is arranged at the lower end surface of the dust cup 110, which can at least shorten the length of the suction connector 103.

[0132] In the embodiment shown in FIG. 3, the suction port connector 103 is mounted on the base 200. The main suction pipe 104 and the suction port connector 103 are located in front of the base 200, away from the motor, and the suction port connector 103 is located at a position for connecting the hose.

[0133] Since the base 200 is heavier than the separation device 100, arranging the main suction pipe 104 and the suction port connector 103 on the base 200 is better than arranging the main suction pipe 104 and the suction port connector 103 on the lower cover 112 of the dust cup. When the user drags the hose, the structure of the whole machine is more stable. Moreover, when the separation device 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 take the separation device 100.

[0134] Arranging the main suction pipe 104 and the suction port connector 103 at the bottom of the dust cup 110 ensures that the fluid flows through the dust cup 110 after entering the suction port connector 103 and then through the motor, and the fluid flow direction is consistent with the internal fluid channel of the cleaning device, ensuring the shortest path of the fluid, reducing fluid loss, and improving the efficiency of the cleaning device.

[0135] As shown in FIG. 2, the shell of the base 200 forms a recessed mounting chamber 201. As shown in FIG. 1, part of the separation device 100 is located in the mounting chamber 201, and the other part is exposed outside the mounting chamber 201.

[0136] In the embodiments 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, the cyclone separation assembly 120 and the dust bag separation assembly 140 are switched, and other operations are performed, the separation device 100 can be taken off from the base 200.

[0137] The detachable connection between the base 200 and the separation device 100 can be a snap connection. As shown in FIG. 2, the base 200 has a clasp 202, and the separation device 100 has a clamping groove 108 (see FIG. 15). After the separation device 100 is placed on the base 200, the clasp 202 is clamped into the clamping groove 108, realizing the connection between the base 200 and the separation device 100. It can be 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.

[0138] In addition, as shown in FIG. 2, the base 200 also has a protrusion, and as shown in FIG. 6a, the bottom of the separation device 100 also has a groove 109, the shape of which matches the protrusion 205. When the separation device 100 is connected to the base 200, the separation device 100 is approximately vertically close to the base 200, the position where the groove 109 at the bottom of the separation device 100 contacts the base 200, and the separation device 100 is rotated about the protrusion 205. The rotation direction is the inclined direction towards the mounting chamber 201 of the base 200, and then the protrusion 205 is clamped into the groove 205.

[0139] Non-limiting, the position where the base 200 and the separating device 100 are connected, the card slot 108 and the groove 205 are respectively located at opposite ends of the separating device 100.

[0140] As shown in FIG. 2, the first inlet 101 and the first outlet 102 are both located between the card hook 202 and the protrusion, that is, the protrusion 205, the first inlet 101, the first outlet 102 and the card hook 202 are sequentially arranged, and the card hook 202 is adjacent to the first outlet 101, and the protrusion 205 is adjacent to the first inlet 101. In this way, the first outlet 101 and the first inlet 101 are not easy to leak at the connecting position of the separating device 100 and the base 200, so as to prevent the connecting position of the separating device 100 and the base 200 from being sealed invalid during use.

[0141] As shown in FIGS. 3-4b, the dust cup 110 comprises a dust cup body 111 and a dust cup lower cover 112, the dust cup body 111 is a hollow piece with an open lower end, and the dust cup lower cover 112 is pivotally connected to the dust cup body 111.

[0142] In an embodiment not shown in the disclosure, the dust cup lower cover 112 can also be connected to the dust cup body 111 in a detachable manner, wherein after the dust cup lower cover 112 is detached, it can be completely separated from the dust cup body 111. The connection manner of the dust cup lower cover 112 and the dust cup body 111 is not limited to this.

[0143] As shown in FIGS. 4a and 4b, the dust cup lower cover 112 can open the lower end opening of the dust cup body 111. As shown in FIG. 3, the dust cup lower cover 112 can also close the lower end opening of the dust cup body 111 to form a first containing space 110a together with the dust cup body 111.

[0144] The first inlet 101 penetrates through the dust cup lower cover 112.

[0145] When the dust cup lower cover 112 is in an open state, the first containing space 110a and the external space are in communication, the dust bag separating assembly 140 and the cyclone separating assembly 120 can be switched through the lower end opening of the dust cup body 111, and the garbage in the first containing space 110a can also be handled through the lower end opening of the dust cup body 111.

[0146] In the embodiments shown in the present disclosure, the cyclone separation assembly 120 and the dust bag separation assembly 140 are separated from the dust cup 110, and the separation direction is along the axis of the dust cup 110 towards the first inlet 101. As shown in FIG. 4a and FIG. 4b, 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 the dust bag separation assembly 140 and the cyclone separation assembly 120 are removed along the axis of the dust cup 110 towards the first inlet 101 after the dust cup 110 is released from the constraint (if any) of the dust bag separation assembly 140 and the cyclone separation assembly 120.

[0147] In the prior art, the cyclone separation assembly is disassembled from the top of the dust cup, and the dust bag is disassembled along the vertical direction of the first inlet, and the disassembly directions of the two are different. In the embodiments of the present disclosure, the dust bag separation assembly 140 and the cyclone separation assembly 120 are removed along the axis of the dust cup 110 towards the first inlet 101, which ensures that the two can share the same dust cup 110.

[0148] As shown in FIG. 3, the separation device 100 further comprises a first filter 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.

[0149] If the cleaning device is in the first use mode, the first filter 130 filters the fluid flowing out from the cyclone separation assembly 120. If the cleaning device is in the second use mode, the first filter 130 filters the fluid flowing out from the dust bag separation assembly 140. If the cleaning device is in the third use mode, the first filter 130 filters the fluid flowing out from the dust bag separation assembly 140 and the cyclone separation assembly 120 at the same time.

[0150] The first filter 130 is filter cotton. In addition, the first filter 130 can also be Hepar, but is not limited thereto.

[0151] In the embodiments of the present disclosure, the filtering level of the first filter 130 is higher than that of the dust bag separation assembly 140, and the filtering level of the dust bag separation assembly 140 is higher than that of the cyclone separation assembly 120. The filtering level is determined according to the minimum diameter of dust that can be filtered, wherein the smaller the minimum diameter of dust that can be filtered, the higher the filtering level; otherwise, the filtering level is lower. Generally, the filtering level of the dust bag separation assembly 140 is higher than that of the cyclone separation assembly 120, and can meet the daily needs of users, that is, the particles in the fluid filtered by the dust bag separation assembly 140 will not damage the internal structure of the motor, so the first filter 130 is only used in the first use mode (that is, only used in the case of using the cyclone separation assembly 120 alone), and therefore the first filter 130 can be arranged integrally with the cyclone separation assembly 120. When the cyclone separation assembly 120 is removed and replaced by the dust bag separation assembly 140, the first filter 130 is also removed. In this way, the fluid loss in the second use mode is reduced, and the service life of the first filter 102 is longer.

[0152] The dust cup body 111 is generally 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. As shown in FIG. 3, the dust cup 110 further comprises a dust cup upper cover 113, which is pivotally connected to the dust cup body 111 to be able to open or close the upper end opening of the dust cup body 111.

[0153] As shown in FIG. 3, the first filter 130 is located below the dust cup upper cover 113 and downstream of the cyclone separation assembly 120 and / or the dust bag separation assembly 140 in the fluid flow direction. After the dust cup upper cover 113 is in the open state, the first filter 130 can be conveniently replaced.

[0154] As shown in FIG. 3, the cyclone separation assembly 120 has a second inlet 1201 for fluid to enter the inside thereof, a second outlet 1202 for fluid to flow out of the inside thereof, and a dust throwing port 1211 (see FIG. 5e), the second inlet 1201 is in communication with the first inlet 101, the second outlet 1202 is in communication with the first outlet 102, and the dust throwing port 1211 is in communication with the first containing space 110a.

[0155] The second inlet 1201 is generally coaxially distributed with the first inlet 101, and the fluid passing through the first inlet 101 enters the second inlet 1201 and then enters the inside of the cyclone separation assembly 120. After the fluid is separated in the cyclone separation assembly 120, the relatively clean fluid flows to the first outlet 102 through the second outlet 1202, and the relatively dirty airflow containing more dust, garbage particles or fragments flows out through the dust throwing port 1211, and finally the solid dirt such as dust, garbage particles or fragments falls to the bottom of the first containing space 110a (i.e. the dust cup lower cover 112) under the action of gravity. After the dust cup lower cover 112 is opened, these solid dirt can fall down.

[0156] Therefore, in combination with the pivotal connection of the dust cup lower cover 112 and the dust cup body 111, and the communication of the dust discharging port 1211 of the cyclone separation assembly 120 and the first containing space 110a, the garbage can be conveniently poured out.

[0157] As shown in FIGS. 5a and 5b, the cyclone separation assembly 120 comprises a cyclone cup 121 and a cyclone bracket 122. The cyclone bracket 122 is located in the cyclone cup 121, and the second inlet 1201 is used for allowing fluid to enter the cyclone cup 121; the cyclone bracket 122 has a spiral surface 1226 extending along the axis of the cyclone bracket 122 from the second inlet 1201 towards the second outlet 1202.

[0158] In combination with FIGS. 5a and 5b, the dust discharging port 1211 is located on the side of the cyclone cup 121, and the second outlet 1202 is located above the dust discharging port 1211.

[0159] As shown in FIGS. 5d and 5e, the spiral surface 1226 can guide the fluid to flow upwards along the axis in a spiral manner, provide tangential acceleration for the fluid, form a vortex, and ensure the separation of the fluid. In the process of the spiral upward flow of the fluid, the heavier fluid containing more dust, garbage particles or fragments is thrown to the dust discharging port 1211 under the action of centrifugal force and enters the first space through the dust discharging port 1211. The lighter fluid containing less dust continues to flow upwards and flows out of the cyclone cup 121 through the second outlet 1202. That is, in the process of the spiral upward flow of the fluid along the spiral surface 1226, the fluid entering the cyclone cup 121 through the second inlet 1201 achieves the purpose of separating solid dirt and dust.

[0160] By arranging the spiral surface 1226, the spiral upward flow of the fluid along the axial direction is achieved, which replaces the scheme of air inlet at the side of the dust cup 110.

[0161] As shown in FIGS. 5e and 5f, the inner wall of the dust discharging port 1211 (referring to the part of the side wall of the cyclone cup 121 forming the dust discharging port 1211) has a guide surface 1212 tangent to the inner wall of the cyclone cup 121. Under the action of the centrifugal force of the vortex fluid, the heavier fluid carrying more solid dirt climbs to the dust discharging port 1211, and the solid dirt is thrown out along a path substantially along the tangential direction of the inner wall of the cyclone cup 121, which is consistent with the inclination direction of the guide surface 1212. Therefore, the guide surface 1212 can more smoothly throw out the solid dirt from the dust cup.

[0162] The inner wall of the dust discharging port 1211 at least partially protrudes out of the cyclone cup 121, which can not only play a better guiding role, but also can place the fluid flowing out of the cyclone cup 121 to flow back into the cyclone cup 121.

[0163] As shown in FIG. 5a, FIG. 5b and FIG. 5d, the cyclone bracket 122 further has an air inlet joint 1221 extending along the axial 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.

[0164] The air inlet joint 1221 extends to the first inlet 101 so as to better connect the first inlet 101 and the internal space of the dust cup 110.

[0165] As shown in FIG. 5d, the transition position of the air inlet joint 1221 and the spiral surface 1226 has a transition slope 1203 for guiding the smooth transition of the airflow to the spiral surface 1226.

[0166] The air inlet joint 1221 is arranged in the axial direction of the cyclone cup bracket 122, the fluid inlet of the spiral surface 1226 is substantially tangent to the radial direction of the cyclone cup bracket 122, and the transition slope 1203 is connected to the air inlet joint 1221 and the spiral surface 1226 respectively and substantially tangentially.

[0167] The transition slope 1203 can be used to smoothly transition the connection between the air inlet joint 1221 and the spiral surface 1226, so that the fluid smoothly transitions at the transition position. Therefore, the transition slope 1203 can be used to reduce the energy loss of the fluid rushing into the cyclone bracket 122.

[0168] As shown in FIG. 5d, the cyclone bracket 122 includes a central portion 125 and a spiral blade 1225, the central portion 125 is a hollow piece with a filter hole 1222; the second outlet 1202 is located in the central portion 125 and downstream of the filter hole 1222 in the fluid flow direction; the spiral blade 1225 extends in the axial direction of the central portion 125, the spiral surface 1226 is the surface of the spiral blade 1225; the filter hole 1222 is located downstream of the spiral blade 1225 in the fluid flow direction.

[0169] As shown by the arrows in FIG. 5e, 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 move in a circular motion upward. As shown by the arrows in FIG. 6b, the suction force provided by the driven member 300 causes the pressure in the central portion 125 to be smaller. The fluid containing less solid dirt can pass through the filter hole 1222 and be sucked into the central portion 125, and finally flow out of the cyclone separation assembly 120 through the second outlet 1202. As shown in FIG. 6b, small particles of dirt in the relatively clean fluid can be adsorbed by the first filter 130, so as to further purify the fluid flowing to the driven member 300 and reduce the influence of the dirt on the driven member 300.

[0170] During the upward flow of the fluid, as shown by the arrows in FIG. 6a, the dust and garbage particles with larger density will be gradually thrown to the periphery under the action of centrifugal force, climb a few rounds along the inner wall of the cyclone barrel, and then be thrown out of the cyclone cup 121 at the ash throwing port 1211 to enter the space between the cyclone cup 121 and the dust cup 110 (i.e., the first partial containing space 110a). The airflow speed between the cyclone cup 121 and the dust cup 110 is low, and the garbage thrown out of the ash throwing port 1211 will rotate around the outside of the cyclone cup 121 under the action of inertial force and gradually deposit at the bottom of the dust cup 110 under the action of gravity.

[0171] The garbage with density close to air and volume greater than the diameter of the filter hole 1222 will be blocked outside the central part 125 where the filter hole 1222 is located, and will be continuously impacted by the subsequent passing fluid to be taken out of the ash throwing port 1211.

[0172] As shown in FIG. 5d, the central part 125 is generally cylindrical. The spiral surface 1226 extends from the outer circumferential surface of the central part 125 to 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 can make the spiral surface 1226 occupy more space between the central part 125 and the cyclone cup 121, and make the fluid entering the cyclone cup 121 form a vortex as much as possible.

[0173] As shown in FIG. 5d, the air inlet joint 1221 is attached to the bottom of the spiral blade 1225 and is eccentrically arranged with the central part 125.

[0174] The spiral blade 1225 is located below the filter hole 1222 and above the air inlet joint 1221.

[0175] Generally, the filter hole 1222 is prone to residual dirt, and the position where the filter hole 1222 is located is dirtier than the air inlet joint 1221. Further, by arranging the filter hole 1222 above the air inlet joint 1221, the user can pinch or hold the cleaner air inlet joint 1221 without touching the dirtier filter hole 1222, thereby improving the user experience.

[0176] The bottom of the central part 125 is closed, and the top is open (i.e., the second outlet 1202), so as to ensure that the fluid entering the central part 125 through the filter hole 1222 continues to flow upward.

[0177] As shown in FIG. 7a, the diameter L3 of the central part 125 is between 1 / 3 and 3 / 5 of the inner diameter L5 of the cyclone cup 121, so that the heavier dirt in the dust and the like can be better separated. In the embodiment shown in the disclosure, L3 is 27 mm, and L5 is 90 mm. For example, the inner diameter of the central part 125 is 1 / 3, 3 / 5 or 7 / 15 of the inner diameter of the cyclone cup.

[0178] The height of the whole helical surface 1226 (i.e. the height of the helical blade 1225) L1 is greater than or equal to the distance L2 from the top end of the helical blade 1225 to the dust outlet 1211. In the embodiment shown in the disclosure, L1 is 60 mm and L2 is 55 mm, so as to ensure that the dust has enough rising force.

[0179] Fig. 5d exemplarily shows the helical blade 1225 rotating less than two circumferences, so as to reduce the pressure drop and make the cyclone separation structure more compact. One circumference refers to the helical blade 1225 rotating 360° around the central part 125. The helical channel 124 is formed between the lower helical blade 1225 and the upper helical blade 1225, and the transition slope 1203 connects the upper helical blade 1225 and the air inlet joint 1221, respectively.

[0180] As shown in Fig. 5b, the cyclone cup 121 and the cyclone support 122 are detachably connected. For the cyclone separation assembly 120, the fluid flows between the cyclone cup 121 and the cyclone support 122 to achieve dust-gas separation, and dirt is easily left between the cyclone cup 121 and the cyclone support 122. The cyclone cup 121 and the cyclone support 122 are arranged to be detachable, so that the cyclone cup 121 and the cyclone support 122 can be cleaned separately.

[0181] As shown in Fig. 5c, the bottom end of the cyclone support 122 has a positioning gap 1223, and as shown in Fig. 5b, the bottom end of the cyclone cup 121 has a positioning protrusion 1213 which is downward along the axial direction, and the positioning protrusion 1213 can be inserted into the positioning gap 1223.

[0182] It can be understood that the positioning gap 1223 can also be arranged at the bottom end of the cyclone cup 121, and the positioning protrusion 1213 is arranged at the bottom end of the cyclone support 122. Alternatively, the cyclone cup 121 and the cyclone support 122 both have the positioning gap 1223 and the positioning protrusion 1213, and the positioning protrusion 1213 and the positioning gap 1223 correspond one by one. When the cyclone cup 121 and the cyclone support 122 are assembled, the corresponding positioning protrusion 1213 is inserted into the corresponding positioning gap 1223.

[0183] The cooperation of the positioning protrusion 1213 and the positioning gap 1223 can limit the relative rotation between the cyclone support 122 and the cyclone cup 121, so as to ensure the reliability of the connection.

[0184] As shown in Fig. 5c, the bottom end of the cyclone support 122 has a flange 1224 which protrudes outwardly from the cyclone support 122, and the flange 1224 has the positioning gap 1223. As shown in Fig. 5a, the bottom end of the cyclone cup 121 abuts against the flange 1224.

[0185] With reference to FIG. 5c and FIG. 7f, the side wall of the cyclone support 122 is provided with a mounting groove 127 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.

[0186] The cyclone cup 121 is a substantially cylindrical structure with an open bottom. When the cyclone support 122 is inserted into the cyclone cup 121 through the open bottom of the cyclone cup 121, the abutment of the flange 1224 and the cyclone cup 121 can remind the two to be installed in place.

[0187] Without limitation, the friction or compression force at the joint of the cyclone cup 121 and the cyclone support 122 can be used to fix the two.

[0188] The flange 1224 is located at the periphery of the helical blade 1225 at the bottom end. When the cyclone support 122 needs to be disassembled, the bottom edge of the cyclone support 122 can be pinched (such as the air inlet connector 1221), and the cyclone support 122 can be separated from the cyclone cup 121 in the axial direction (the direction of the arrow in FIG. 5b).

[0189] As shown in FIG. 5a, the cyclone separation assembly 120 further comprises a cyclone cover plate 123. The cyclone cover plate 123 is located at the top end of the cyclone cup 121, and covers the gap between the cyclone cup 121 and the cyclone support 122, and is sealingly connected with the cyclone cup 121 and the cyclone support 122, respectively.

[0190] The top of the cyclone cup 121 also has an opening, and the central portion 125 of the cyclone support 122 is substantially coaxial with the cyclone cup 121. The cyclone cover plate 123 covers the top opening of the cyclone cup 121 and has a through hole 1232 (as shown in FIG. 5e) communicating with the second outlet 1202. The through hole 1232 can avoid the shielding of the second outlet 1202 by the cyclone cover plate 123, and ensure that the cyclone cup 121 and the cyclone support 122 flow out through the second outlet 1202.

[0191] As shown in FIG. 7e, the cyclone cover plate 123 has a lip 1231 extending to the inner wall of the second outlet 1202, and the lip 1231 is sealingly connected 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 out through the second outlet 1202, and limit the leakage of fluid through the joint of the cyclone cover plate 123 and the central portion 125.

[0192] The lip 1231 and the central portion 125 at least coincide in the axial direction by 1-10 mm, and the inner and outer surfaces of the joint of the lip 1231 and the central portion 125 are smoothly transitioned, and the thickness of the lip 1231 is between 0.2-0.7 of the main wall thickness. In this way, the loss of fluid in the central portion 125 can be small, and the airflow entering the central portion 125 through the filter holes 1222 can better flow into the second outlet 1202.

[0193] Exemplarily, the lip 1231 is 0.1 mm, 0.15 mm, or 0.5 mm thick in the axial direction from the center portion 125. The thickness of the lip 1231 is 0.2 mm, 0.3 mm, 0.25 mm, 1 mm, or 1.5 mm.

[0194] As shown in FIG. 7e, the cyclone cover plate 123 is circularly arc transitioned at the transition from the longitudinal direction to the transverse direction, which can further reduce the loss of flow rate of the fluid. The longitudinal direction of the cyclone cover plate 123 is connected to the center portion 125, and the transverse direction is connected to the sidewall of the cyclone cup 121.

[0195] The cyclone cover plate 123 and the cyclone cup 121 are fixedly connected and cannot be detached. The two can be fixedly connected by ultrasonic welding. In addition, the fixed connection of the cyclone cover plate 123 and the cyclone cup 121 can also be achieved by screw connection, adhesive connection, or other welding methods.

[0196] 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 of 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 separation of the cyclone separation assembly 120 and the dust cup 110 can be achieved.

[0197] Optionally, the cyclone cup 121 can be directly connected to the dust cup 110 to achieve the detachability of the cyclone separation assembly 120.

[0198] As shown in FIGS. 7a and 7b, in the embodiment shown in the 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 comprises: a cyclone cup fixing frame 150 located in the first containing space 110a, the cyclone cup fixing frame 150 has a first clamping portion, the cyclone cup 121 has a second clamping portion, and the first clamping portion and the second clamping portion are clamped to achieve detachable connection between the cyclone cup 121 and the cyclone cup fixing frame 150.

[0199] As shown in FIGS. 7c and 7d, the first clamping portion is a clamping groove 151, and the second clamping portion is a protruding clamping block 1214 which can be inserted into the clamping groove 151. It can be understood that the first clamping portion can also be a clamping block, and the second clamping portion is a clamping groove. Alternatively, the first clamping portion and the second clamping portion both comprise clamping blocks and clamping grooves, and the clamping grooves and the clamping blocks are one-to-one corresponding. When the cyclone cup fixing frame 150 and the cyclone cup 121 are connected, the clamping blocks can be inserted into the corresponding clamping grooves.

[0200] As shown in Figures 7c and 7d, 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.

[0201] 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.

[0202] 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.

[0203] The cyclone separation assembly 120 can be installed in the dust cup 110 by rotating. The cyclone separation assembly 120 can also be removed from the dust cup 110 by rotating (as shown by the arrow direction in Figure 4a), and the rotation directions of removal and installation are opposite. In this process, the cooperation between the positioning protrusion 1213 and the positioning notch 1223 can also provide positioning for the cooperation between the card block and the card slot. The positioning protrusion 1213 is larger in size and is easier to insert into the positioning notch 1223. After the positioning protrusion 1213 is inserted into the positioning notch 1223, the corresponding card block will also be inserted into the card slot.

[0204] As shown in FIG7f , the separation device 100 further includes a first sealing member 160 positioned within the first inlet 101. When the cyclone separation assembly 120 is installed within 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 within 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.

[0205] 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.

[0206] The first seal 160 is connected with the dust cup lower cover 112, and can be fixed by the cover of the dust cup lower cover 112, so that the first seal 160 is tightly abutted against the cyclone support 122 or the dust bag separation assembly 140, to realize the sealing of the upper end (i.e. the downstream side) of the first seal 160. After the separation device 100 is installed on the machine base 200, the first seal 160 can also be tightly abutted against the suction port connector 103 by the gravity of the separation device 100, to realize the sealing of the lower end (i.e. the upstream side) of the first seal 160. The sealing mode of the first seal 160 can reduce the use of screws.

[0207] As shown in FIGS. 7a and 7f, the first seal 160 is a generally cylindrical sealing ring, which is coaxial with the first inlet 101. The first sealing ring can be made of soft material, for example, silica gel.

[0208] In FIG. 7f, the air inlet connector 1221 of the cyclone support 122 is abutted against the first seal 160 to realize the sealing connection.

[0209] Referring to FIG. 10b, the bottom end of the dust bag separation assembly 140 also has a dust bag connector 143, which can be of the same specification as the air inlet connector 1221 of the cyclone support 122, and the two can be universal. When the dust bag separation assembly 140 is installed in the dust cup 110, one end of the first seal 160 is sealingly connected with the dust bag connector 143.

[0210] In the embodiments 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,

[0211] As shown in FIGS. 7a and 7f, the first seal 160 includes a sealing body 161 and sealing lips 162 located at the upper and lower ends of the sealing body 161, respectively. The sealing body 161 is connected to the dust cup lower cover 112 to realize the fixation of the first seal 160.

[0212] The sealing lips 162 extend outwardly from the first inlet 101, and the bottom end of the suction port connector 103 and the cyclone support 122 are sealingly connected with the corresponding sealing lips 162. The first seal 160 is sealingly connected with the separation device 100 and the suction port connector 103 by the sealing lips 162, respectively. For example, as shown in FIG. 7f, the sealing body 161 can be clamped between two components in the dust cup lower cover 112, to realize the fixation of the first seal 160.

[0213] The first seal 160 is a symmetrical member, that is, the sealing lips 162 on the upper and lower sides of the sealing body 161 are symmetrically distributed. In this way, the upper and lower ends of the first seal 160 have no directionality, which reduces the problem of reverse installation during assembly and facilitates installation.

[0214] As shown in FIG. 7f, the sealing lip 162 is shaped to extend outwardly and upwardly from the sealing body 161, and the thickness gradually decreases outwardly and upwardly. When the motor is started and fluid passes through the first seal 160, the top of the sealing lip 162, which is thinnest, is first affected by the vacuum and tends to straighten, thereby better sealing the top of the sealing lip 162 with the end of the cyclone cup support 122, i.e., the air inlet connector 1221.

[0215] In the axial direction, the inner surface of the fluid passage of the first seal 160 can be formed by two sealing lips 162 spliced together, or the sealing body 161 provides at least part of the fluid passage. The sealing body 161 providing the fluid passage can make the structure of the sealing lip 162 more stable, and also reduce the possibility of the dust bag separation assembly 140 or the cyclone separation assembly 120 contacting the suction port connector 103.

[0216] The side outer surface of the first seal 160 is generally T-shaped, which facilitates the secure installation of the first seal 160 and effectively ensures the axial positioning of the sealing lip 162.

[0217] As shown in FIG. 7f, the cyclone separation assembly 120 further includes a second seal 170 between the bottom end of the cyclone cup 121 and the cyclone support 122, and the second seal 170 is sealingly connected to the bottom end of the cyclone cup 121 and the cyclone support 122, respectively.

[0218] The second seal 170 can achieve sealing at the bottom connection between the cyclone cup 121 and the cyclone support 122, thereby reducing air leakage.

[0219] The second seal 170 can also be a soft rubber seal.

[0220] As can be seen, in the cyclone separation assembly 120, the cyclone cup 121, the cyclone support 122, the cyclone cover plate 123, and the second seal 170 all do not have special waterproof requirements. Therefore, the disassembled cyclone separation assembly 120 can be cleaned and dried, further facilitating the cleaning of the cyclone separation assembly 120.

[0221] In the embodiments shown in the present disclosure, the top of the cyclone cup 121 does not have a seal due to the small pressure difference and for the convenience of installation. In some embodiments not shown in the present disclosure, a soft rubber seal can be provided at the top of the cyclone cup 121 to enhance the sealing of the cyclone separation assembly 120. Exemplarily, the seal can be located between the cyclone cup 121 and the cyclone cover plate 123 and sealingly connected to both.

[0222] As shown in FIG. 7f, 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 in the axial direction of the first seal 160; the second seal 170 has a ring-shaped protrusion 171 protruding towards the cyclone cup 121, and the distance between the ring-shaped protrusion 171 and the bottom end of the cyclone cup 121 is greater than or equal to the movable distance.

[0223] The ring-shaped protrusion 171 can enhance the sealing performance of the second seal 170.

[0224] The distance between the ring-shaped protrusion 171 and the bottom end of the cyclone cup 121 being greater than or equal to the movable distance can further ensure the sealing performance of the second seal 170.

[0225] As shown in FIG. 7g and FIG. 7j, according to some optional embodiments, the separating device 100 further comprises a leak-proof assembly movably connected to the dust cup 110, and the leak-proof assembly has a first state and a second state.

[0226] In the embodiments shown in the present disclosure, when the leak-proof assembly is in the first state, the leak-proof assembly blocks the connection between different components of the dust cup 110 (FIG. 7i and FIG. 7j), and when the leak-proof assembly is in the second state, the leak-proof assembly allows the connection between different components of the dust cup 110 (FIG. 7g and FIG. 7h).

[0227] The different components of the dust cup 110 include the dust cup lower cover 112 and the dust cup body 111, or the dust cup upper cover 113 and the dust cup body 111.

[0228] In the embodiments not shown in the present disclosure, when the leak-proof assembly is in the first state, the leak-proof assembly blocks the connection between the dust cup 110 and the base 200; and when the leak-proof assembly is in the second state, the leak-proof assembly allows the connection between the dust cup 110 and the base 200.

[0229] In the embodiments shown in the present disclosure, as shown in FIG. 7i and FIG. 7j, when the leak-proof assembly is in the first state, the leak-proof assembly is partially located in the closing track of the dust cup lower cover 112 (approximately as shown by the arc-shaped dashed line in FIG. 7g) to limit the connection between the dust cup lower cover 112 and the dust cup body 111. In the first state, the dust cup lower cover 112 cannot be closed on the dust cup body 111 under the blocking action of the leak-proof assembly.

[0230] As shown in FIG. 7g and FIG. 7h, when the leak-proof assembly is in the second state, the leak-proof assembly is located outside the closing track of the dust cup lower cover 112 to allow the connection between the dust cup lower cover 112 and the dust cup body 111. At this time, the leak-proof assembly does not have a blocking action, and the dust cup lower cover 112 can be closed on the dust cup body 111.

[0231] When the cyclone separation assembly 120 and the dust bag separation assembly 140 are both detachably mounted in the dust cup, the risk of missing installation is easy to occur. The anti-missing assembly can prevent missing installation of the cyclone separation assembly 120 or the dust bag separation assembly 140, and ensure that the separation assembly has dust gas separation function when it is normally used. In this way, the risk of more dirt entering the base 200 and damaging the driving member 300 due to missing installation of the cyclone separation assembly 120 or the dust bag separation assembly 140 is reduced.

[0232] When the cyclone separation assembly 120 or the dust bag separation assembly 140 is installed in the dust cup 110, the anti-missing 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 anti-missing assembly can be switched from the second state to the first state.

[0233] As shown in FIGS. 7h-7k, the anti-missing assembly includes a top rod 180 connected to the dust cup lower cover 112 and an elastic member 182. The elastic member 182 provides the top rod 180 with a first driving force (the direction of the first driving force is the arrow direction in FIG. 7k) toward the closed track of the dust cup lower cover 112. 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 to the top rod 180 opposite to the first driving force, so that the anti-missing assembly is in the second state.

[0234] When the top rod 180 is not subjected to external force, the elastic force of the elastic member 182 drives the top rod 180 in the closed track of the dust cup lower cover 112 as the first driving force, so as to limit the connection of the dust cup lower cover 112 and the dust cup main body 111.

[0235] 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 external force (i.e. the second driving force) to the top rod 180 to push the top rod 180 to move the elastic member 182, overcoming the first driving force of the elastic member 182. At this time, the top rod 180 is located outside the closed track to allow the connection of the dust cup lower cover 112 and the dust cup main body 111. The elastic member 182 stores the elastic deformation force.

[0236] 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 restores the deformation to generate the first driving force, and the anti-missing assembly returns to the first state.

[0237] FIG. 7k exemplarily shows that the elastic member 182 is a torsion spring. It can be understood that the elastic member 182 can also be a compression spring, a tension spring, or other structures such as a spring sheet.

[0238] As shown in FIG. 7k and FIG. 8, the top rod 180 is distributed around the first entrance 101, that is, the top rod 180 has an avoiding opening 181 avoiding the first entrance 101. And the top rod 180 has a first convex part 1801 and a second convex part 1802, the first convex part 1801 has a guide slope 1805 guiding the cyclone separation assembly 120 or the dust bag separation assembly 140 to enter the first entrance 101.

[0239] When the anti-leakage assembly is in the first state, as shown in FIG. 7j, the first convex part 1801 is at least partially located in the first entrance 101, and the second convex part 1802 is at least partially located in the closing track, and the second convex part 1802 will block the dust cup lower cover 112 during the covering process, that is, the second convex part 1802 conflicts with the dust cup lower cover 112, and the dust cup lower cover 112 cannot be covered on the dust cup main 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 convex part 1801, and the top rod 180 is moved in the opposite direction (that is, in the opposite direction of the arrow in FIG. 7k) to move the first convex part 1801 out of the first entrance 101, and the second convex part 1802 is located outside the closing track.

[0240] When the cyclone separation assembly 120 is installed in the dust cup 110, the air inlet joint 1221 is inserted into the avoiding opening 181 and contacts the guide slope 1805 of the first convex part 1801. When the dust bag separation assembly 140 is installed in the dust cup 110, the dust bag joint 143 is inserted into the avoiding opening 181 and contacts the guide slope 1805 of the first convex part 1801.

[0241] The guide slope 1805 has a guiding effect on the insertion of the cyclone separation assembly 120 or the dust bag separation assembly 140, which can make the insertion more smooth, and also facilitate the pulling out of the cyclone separation assembly 120 or the dust bag separation assembly 140 from the avoiding opening 181.

[0242] As shown in FIG. 7j, the anti-leakage assembly is located inside the dust cup lower cover 112, so that the influence of dust and dirt on the anti-leakage assembly can be reduced. As shown in FIG. 7i, the dust cup lower cover 112 further comprises a cover plate 183 covering the anti-leakage assembly, and the anti-leakage assembly is located in the spacing space between the cover plate and the bottom wall of the dust cup lower cover 112.

[0243] In the second use mode, the dust is retained in the dust bag separation assembly, and in the first use mode, the dust is scattered on the dust cup lower cover 112 and the inner wall of the dust cup 110. By arranging the anti-leakage assembly inside the dust cup lower cover 112 instead of arranging it 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.

[0244] The space between the cover plate 183 and the bottom wall of the dust cup lower cover 112 forms a space for the top rod 180 to move. The cover plate 183 limits and protects the top rod 180, and limits the dirt from entering the space between the cover plate 183 and the bottom wall of the dust cup lower cover 112 to affect the movement of the top rod 180.

[0245] As shown in FIGS. 7j-8, the leak-proof assembly further includes a third sealing member 1803 connected to the first protrusion 1801 to form a sealing structure at the moving position of the first protrusion 1801, limiting the dirt from blocking the moving path of the first protrusion 1801, and a fourth sealing member 1804 connected to the second protrusion 1802 to form a sealing structure at the moving position of the second protrusion 1802, limiting the dirt from blocking the moving path of the second protrusion 1802.

[0246] When the leak-proof assembly switches between the first state and the second state, the first protrusion 1801 and the second protrusion 1802 need to frequently enter and exit the space between the cover plate 183 and the bottom wall of the dust cup lower cover 112. By arranging the third sealing member 1803 and the fourth sealing member 1804, the moving positions of the two protrusions can be sealed, further reducing the dirt from entering the space between the cover plate 183 and the bottom wall of the dust cup lower cover 112 to affect the movement of the top rod 180.

[0247] As shown in FIG. 8, the third sealing member 1803 is a rubber structure formed on the first protrusion 1801, and the fourth sealing member 1804 is a rubber structure formed on the second protrusion 1802.

[0248] The rubber structure has a better fixing effect on the top rod 180 and will not move during the movement of the top rod 180, which can better ensure the sealing effect of the top rod 180 in the moving state.

[0249] As shown in FIG. 9, 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 appearance panel of the dust cup lower cover 112, the first cover 112a has a third clamping portion 112c, the dust cup has a fourth clamping portion 110b, and the fourth clamping portion 110b is clamped with the third clamping portion 112c after the dust cup lower cover 112 is combined with the dust cup 110. The spring 184 is located between the first cover 112a and the second cover 112b and provides a third driving force for driving the first cover 112a away from the dust cup 110, as shown in FIG. 9, the third driving force is used to strengthen the clamping of the fourth clamping portion 110b and the third clamping portion 112c.

[0250] The use of the spring 184 can reduce the risk of disengagement of the fourth clamping portion 110b and the third clamping portion 112c, and ensure the reliability of the connection between the dust cup lower cover 112 and the dust cup 110.

[0251] As shown in FIG. 9, the third clamping portion 112c and the fourth clamping portion 110b are both hooks.

[0252] As shown in FIG. 9, the first cover 112a and the second cover 112b clamp the sealing body 161 of the first seal 160 therebetween to achieve fixation of the first seal 160.

[0253] As shown in FIGS. 10a and 10b, the dust bag separation assembly 140 includes a dust bag 141 and a dust bag holder 142, the dust bag holder 142 having a third inlet 1204 (as shown in FIG. 10b) in communication with the interior space of the dust bag 141, the third inlet 1204 being located at the bottom end of the dust bag holder 142 and capable of being docked with the first inlet 101.

[0254] The dust bag joint 143 is located at the bottom of the dust bag holder 142 and extends toward the first inlet 101, and the two can be an integral component. The inlet of the dust bag joint 143 is the third inlet 1204.

[0255] The dust bag joint 143 extends from the dust bag holder 143 toward the first inlet 101. It is in the shape of a cylinder that generally fits the first inlet 101 and is slightly smaller in size than the inlet.

[0256] As shown in FIG. 10b, the dust bag joint 143 can be provided with guide ribs 1431 on the outside.

[0257] The dust cup lower cover 112 partially protrudes into the interior of the dust cup 110 around the first inlet 101, i.e., as shown in FIGS. 7i and 7j, the cover plate 183 is arched upward. This partial protrusion can facilitate the installation of a leak-proof device below the cover plate 183 and can also lengthen the installation guide length of the dust bag joint 143 and the dust cup lower cover 112.

[0258] In the embodiments of the present disclosure, at least part of the separation assembly bottom is inserted into the dust cup lower cover 112. The position of the insertion in the dust cup lower cover 112 can be the partially protruding portion. This structure can enable the dust cup lower cover 112 to have a certain “wrapping” effect on the separation assembly, reduce dust accumulation, and further improve the cleanliness inside the dust cup 110.

[0259] In the direction of fluid flow, if the dust bag separation assembly 140 is installed in the dust cup 110, the dust bag joint 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 joint 1221 is at least partially inserted into the dust cup lower cover 112.

[0260] The bottom of the separation assembly includes a gripping portion for dismounting and mounting 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 gripping portion.

[0261] The holding part is at least partially inserted into the first inlet 101; the holding part of the cyclone separation assembly 120 is the air inlet joint 1221, and the holding part of the dust bag separation assembly 140 is the dust bag joint 143. In summary, the air inlet joint and the dust bag joint 143 not only can communicate with the first inlet 101 as a fluid passage, but also can trigger the state switching of the anti-misassembly assembly after being inserted into the first inlet 101, and can also serve as a holding part to facilitate the disassembly and assembly of the separation assembly, achieving multiple purposes at once.

[0262] The part (for example, the air inlet joint 1221 or the dust bag joint 143) of the separation assembly that is inserted into the dust cup lower cover 112 has a guiding effect and can provide friction for the disassembly and assembly of the cyclone separation assembly 120 and the dust cup 110. The user can achieve the installation and disassembly of the cyclone separation assembly 120 by rotating the holding part up and down, or the user can achieve the disassembly and assembly of the cyclone cup 121 and the cyclone support 122 by holding the holding part.

[0263] As shown in FIG. 10a, the dust bag joint 143 abuts against the first sealing member 160 to achieve a sealed connection. The lower end surface of the dust bag joint 143 contacts the upper surface of the sealing body 161, and when the motor is started and fluid passes through the first sealing member 160, the top of the sealing lip 162 is affected by the vacuum first because it is the thinnest, and thus has a tendency to straighten, and the top of the sealing lip 162 can better seal the dust bag joint 143.

[0264] Without limitation, other structures of the dust bag joint 143 and the relationship between the dust bag joint 143 and other structures in the dust cup 110 can be the same as the air inlet joint 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 one first inlet 101 can be adapted to the cyclone separation assembly 120 and the dust bag separation assembly 140, respectively, improving the utilization rate of the first inlet 101.

[0265] As shown in FIG. 3, the cleaning device further comprises a driving member 300 for providing suction force; as shown in FIG. 11, the base 200 has a third outlet 203 for fluid to flow to an external space, and a fluid passage that communicates the first outlet 102 and the third outlet 203, the fluid passage referring to the flow channel of the fluid in the base 200. The fluid flowing out of the separation device 100 enters the base 200 and finally flows to the external space through the third outlet 203.

[0266] Compared with the prior art, the dust bag 141 is taken out and replaced by pivoting the lower dust cup cover 112, as shown in FIG. 4b. After the lower dust cup cover 112 is closed, the first sealing element 160 is compressed to achieve sealing at the first inlet 101, and a sealing element is arranged around the lower dust cup cover 112 to achieve sealing at the connection between the lower dust cup cover 112 and the main dust cup body 111. Thus, the sealing mode for ensuring the vacuum degree is simpler.

[0267] As shown in FIG. 10b, the dust bag support 142 also has a notch 1401, and the main dust cup body 111 has a corresponding protrusion that 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.

[0268] As shown in FIG. 11, the base 200 includes a housing and a cover 210 located in the housing. 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 communicates with the third accommodating space 204. The inner cover 230 is located in the third accommodating space 204.

[0269] As shown in FIG. 13, 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 to form an inner cavity 234. The outer wall 232 extends axially from the bottom wall 231 to form an outer cavity 235. 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. The outer wall has a second through hole 2321 for fluid to flow from the outer cavity 235 to the space between the inner cover 230 and the outer cover 220.

[0270] The outer cover 220, the inner cover 230, and the driving member 300 jointly form a fluid channel.

[0271] As shown in FIGS. 11-13, the fluid discharged by 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 (i.e., part of the third accommodating space 204) through the second through hole 2321, and finally flows out of the outer cover 220 to the third outlet 203.

[0272] The driving member 300 and the inner cover 230 are connected by a high-density sponge to reduce noise. The driving member 300 and the inner cover 230 can jointly form an upstream air duct. After the fluid is discharged from the inner cover 230, it enters another air duct composed of the inner cover 230 and the outer cover 220, and the airflow flows as shown in FIGS. 11-13.

[0273] As shown in FIG. 11, the outer cover 220 includes an upper cover 221 and a lower cover 222 covering an opening of the upper cover 221. The upper cover 221 and the lower cover 222 together form a third accommodating space 204 accommodating the inner cover 230.

[0274] As shown in FIG. 14d, the third outlet 203 is substantially perpendicular to the axial direction of the motor (i.e., the driving member 300) and is located on the right side of the motor. The axial direction of the third outlet 203 is perpendicular to the axial direction of the motor, which is more convenient for air flow. During use of the cleaning device, a user generally holds the hose with the right hand and stands on the left side of the cleaning device. The third outlet 203 located on the right side reduces the possibility of air flow blowing to the user, thereby improving the user experience.

[0275] The third outlet 203 includes a first sub-outlet 203a on the outer shell and a second sub-outlet 203b on the sidewall of the upper cover 221 (FIG. 12). The first sub-outlet 203a is coaxial with the second sub-outlet 203b. 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 the external environment.

[0276] The high-speed fluid has a reduced air flow speed after passing around the inner cover 230 and the outer cover 220. Moreover, this structure has two more walls than the straight-out structure in which the fluid directly flows from the driving member 300 to the third outlet 203. Both of the above factors can reduce noise.

[0277] As shown in FIG. 13, the first through hole 2331 and the second through hole 2321 are distributed away from each other, which can prolong the flow path of the fluid in the inner cover 230 and be conducive to further reducing the fluid speed.

[0278] As shown in FIG. 12, the third outlet 203 and the second through hole 2321 are distributed away from each other. This can prolong the flow path of the fluid between the inner cover 230 and the outer cover 220, which is conducive to further reducing the fluid speed.

[0279] The cleaning device further includes a fifth sealing member and a sixth sealing member. The fifth sealing member is sealingly connected with the driving member 300 and the inner wall, respectively, to limit the fluid from flowing out of the inner cavity 234 through the connection between the driving member 300 and the inner wall. The sixth sealing member is sealingly connected with the outer wall and the outer cover 220, respectively, to limit the fluid from flowing out of the outer cavity 235 through the connection between the outer wall and the outer cover 220.

[0280] As shown in FIGS. 14a and 14b, the cleaning device further includes a second filtering member 240 located in the third outlet 203. The second filtering member 240 has a fragrance mounting position on the outer side away from the driving member 300.

[0281] The aromatherapy installation position is used to install the aromatherapy piece 250. The aromatherapy installation position is arranged at the third outlet 203, which can ensure that the user can smell the fragrance as soon as the cleaning device is started. The fragrance of the aromatherapy piece 250 is blown away by the outlet of the third outlet 203, which is beneficial to expand the fragrance range and diffusion speed, and make the fragrance more concentrated. The aromatherapy piece 250 can cover the odor that may exist during cleaning, and improve the user experience.

[0282] If the motor power is large, or the motor works for a long time, or the motor rotates at a high speed, etc., the air flowing out of the third outlet 203 will be heated, and the heated air can further accelerate the flow of the fragrance when passing through the aromatherapy installation position. The second filter 240 is a hepa, and the aromatherapy installation position is a mounting hole 241 formed on the outer filter frame of the hepa. The mounting hole 241 reduces the shielding of the aromatherapy piece 250 as much as possible, and further makes the aromatherapy piece 250 better volatilize the fragrance.

[0283] The hepa is generally cylindrical, and the second filter 240 and the winding device 280 which are also cylindrical are arranged on the left and right sides of the motor respectively. By such arrangement, the length of the cleaning device is reduced, and the weight is concentrated in the same place, so that the stability of the device is better, and the user experience is improved.

[0284] As shown in FIG. 14b, the hole wall of the mounting hole 241 has a notch 242 for taking and placing the aromatherapy piece 250.

[0285] The notch provides an operable position for the user to take and place the aromatherapy piece 250. For example, two notches 242 can be symmetrically arranged on the radial sides of the mounting hole 241, and when taking and placing the aromatherapy piece 250, two fingers can be placed in the corresponding notches 242 to clamp the aromatherapy piece, which is convenient for taking and placing the aromatherapy piece.

[0286] The aromatherapy piece 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 piece 250 can also be a semi-solid. The specific form of the aromatherapy piece 250 is not limited to the present application.

[0287] FIGS. 14a-14c exemplarily show a generally ring-shaped aromatherapy piece 250, which can increase its contact area with the fluid, further improving the aromatherapy effect.

[0288] As shown in FIG. 14c, an air outlet cover 270 is further arranged outside the aromatherapy piece 250, and the aromatherapy piece 250 is located between the second filter 240 and the air outlet cover 270. The third outlet 203 is partially formed on the air outlet cover 270.

[0289] As shown in FIG. 14b, the depth of the mounting hole 241 is greater than the thickness of the aromatherapy piece. In this way, the aromatherapy piece is protected to a certain extent. For example, when the cleaning device is collided by an external object, the external object will first contact the hole wall of the mounting hole 241, and will not touch the aromatherapy piece.

[0290] As shown in FIG. 14b, the hole wall of the mounting hole 241 has a limiting buckle 260 for limiting the aromatherapy piece 250 within the mounting hole 241.

[0291] The limiting buckle 260 can better fix the aromatherapy within the mounting hole 241, ensuring the reliability of the aromatherapy fixation.

[0292] Taking the second filter piece 240 as an example, the HEPA includes a frame located on the outer side and an internal filter piece 242 located within the frame. The mounting hole 241 and the limiting buckle 260 are both located on the frame 241, and the aromatherapy is located between the limiting buckle 260 and the internal filter piece 242.

[0293] The limiting buckle 260 has an inclined surface 261 for guiding the aromatherapy piece 250 to be clamped into the mounting hole 241. The inclined surface 261 can better guide the aromatherapy to be clamped into the mounting hole 241.

[0294] The separating device 100 further includes at least one of the dust cup release key 107a, the dust cup upper cover release key 105, and the dust cup lower cover release key 106 located on the dust cup 110.

[0295] The dust cup release key 107a, when triggered, can separate the dust cup 110 from the base 200 of the cleaning device, facilitating the disassembly of the separating device 100 from the base 200.

[0296] The dust cup upper cover release key 105, when triggered, can open the dust cup upper cover 113, facilitating the replacement of the first filter piece 130.

[0297] The dust cup lower cover release key 106, when triggered, can open the dust cup lower cover 112, facilitating the dumping of the residual garbage in the dust cup 110.

[0298] FIG. 15 exemplarily shows that the dust cup 110 simultaneously has the dust cup release key 107a, the dust cup upper cover release key 105, and the dust cup lower cover release key 106.

[0299] Exemplarily, as shown in FIG. 14a and FIG. 15, the dust cup upper cover 113 has a first handle 107, the dust cup release key 107a is located at the top of the first handle 107, and the dust cup upper cover release key 105 and the dust cup lower cover release key 106 are both located on the side of the dust cup 110.

[0300] In combination with FIG. 14b, the dust cup lower cover release key 106 is located on the side of the dust cup facing the base 200, so as to reduce the risk of accidental triggering of the dust cup lower cover release key 106.

[0301] The following describes a third use mode of the cleaning device in the embodiments of the present disclosure.

[0302] Exemplarily, the dust bag separation assembly 140 has a second containing space; when the separation device 100 is in the third use mode, the cyclone separation assembly 120 is at least partially located in the second containing space, and the dust bag separation assembly 140 filters the fluid downstream of the cyclone separation assembly 120.

[0303] In the third use mode, the dust outlet 1211 of the cyclone separation assembly 120 is in communication with the internal space (i.e., the second containing space) of the dust bag separation assembly 140. The dust bag can further filter the fluid separated by the cyclone separation assembly 120.

[0304] The structure of the dust bag separation assembly 140 can be seen from the dust bag assembly shown in FIG. 10b. At the bottom end of the dust bag separation assembly 140, the dust bag joint 143 can be larger than the air inlet joint, and the two can be sleeved. At the top end of the dust bag separation assembly 140, the dust bag can be partially clamped between the cyclone cup 121 and the cyclone cup fixing frame 150, and the fluid flowing out of the second outlet 1202 of the cyclone support 122 flows to the first filter 130 after being filtered by the dust bag.

[0305] FIGS. 16-19 exemplarily show a structure schematic diagram of a handheld cleaner.

[0306] Unlike the horizontal cleaner shown in FIGS. 1 and 2, the separation device 100 of the cleaner shown in FIGS. 16-19 only has the end (the bottom end shown in the figure) in contact with the base 200. The base 200 is provided with a second handle 290 for the user to grip.

[0307] Generally, the first suction port of the handheld cleaner (which is equivalent to the main suction pipe 104 shown in FIG. 16) is not connected to a hose, but is connected to a hard suction pipe.

[0308] In the handheld cleaner, the suction port connector is installed at the bottom of the separation device 100. In FIGS. 16-19, the suction port connector is not shown, and its structure can be referred to the suction port connector 103 in FIG. 13.

[0309] As shown in FIG. 17, the dust cup lower cover 112 of the handheld cleaner is pivotally connected to the dust cup body 111. After the dust cup lower cover 112 is opened, the cyclone separation assembly 120 (as shown in FIG. 18) and the dust bag separation assembly 140 (as shown in FIG. 19) can be respectively installed in the dust cup 110.

[0310] The other structures of the above-mentioned handheld cleaner can be the same as the corresponding structures of the above-mentioned horizontal cleaner, and will not be repeatedly described here.

[0311] The cleaning equipment of the embodiments of the present disclosure is not limited to horizontal cleaners and handheld cleaners, but can also be barrel cleaners, upright cleaners, etc.
