After the vacuum cleaner is started, the dust-laden air enters the dust cup through the dust suction port, the dust-laden air rotates around the cyclone cone and dust and gas separation is performed.

[0004] However, in the related art, the garbage that sinks to the bottom of the dust cup after dust and gas separation is easy to block the dust outlet at the bottom of the dust cup, thereby causing a technical problem of poor dust collection effect. Utility Model Content

[0005] In view of the above problems, the embodiments of the present application provide a dust cup assembly and a vacuum cleaner, which solve the problem that garbage easily blocks the dust outlet, thereby improving the dust collection effect.

[0006] In order to achieve the above objectives, the embodiments of the present application provide the following technical solutions:

[0007] A first aspect of an embodiment of the present application provides a dust cup assembly, comprising: a dust cup and an air duct member; the air duct member is arranged in the dust cup; and one end of the air duct member passes through the bottom wall of the dust cup, and an annular dust and gas separation chamber is formed between the outer wall of the air duct member and the inner wall of the dust cup; the air duct member has an air duct extending along a first direction, and an end of the air duct facing the bottom wall of the dust cup has a dust suction port connected to the outside, and an end of the air duct member away from the dust suction port has a dust outlet, and the dust outlet connects the air duct and the dust and gas separation chamber, so that the dust and gas sucked into the air duct enters the dust and gas separation chamber through the dust outlet for dust and gas separation; wherein the first direction is the height direction of the dust cup.

[0008] In the dust cup assembly provided in the embodiment of the present application, a duct member is designed, which is located in the dust cup, and an annular dust and gas separation chamber is formed between the outer wall of the duct member and the inner wall of the dust cup, and the duct member has an air duct connected to the dust suction port and extending along a first direction, and a dust outlet connecting the air duct and the dust and gas separation chamber is arranged at one end of the duct member close to the top of the dust cup. In this way, after the dust and gas entering the dust and gas separation chamber through the dust outlet are separated, the separated large particles of garbage sink to the bottom of the dust and gas separation chamber. Since the position of the dust outlet is higher than the bottom of the dust and gas separation chamber, the problem of garbage after dust and gas separation easily clogging the dust outlet can be avoided, thereby improving the dust suction effect and improving the utilization rate of the dust cup.

[0009] In some embodiments, the contour of the dust outlet is inclined toward one side of the dust suction port.

[0010] Such an arrangement can provide the dust gas at the dust outlet with an oblique downward movement direction, so that the dust gas can enter the dust and gas separation chamber and be separated, thereby improving the efficiency of the dust gas entering the dust and gas separation chamber.

[0011] In some embodiments, the outline of the dust outlet is an arc-shaped structure inclined toward one side of the dust suction port.

[0012] Such an arrangement can further improve the efficiency of dust and gas entering the dust and gas separation chamber.

[0013] In some embodiments, the air duct member includes an air duct portion, the air duct portion is a cylindrical structure extending along the first direction, and the air duct is formed in the air duct portion.

[0014] In this arrangement, an air duct portion is arranged in the air duct member, and the dust outlet is arranged on the air duct portion. In this way, the position of the dust outlet is raised to avoid the problem of garbage blocking the dust outlet, thereby improving the dust collection effect.

[0015] In some embodiments, the air duct component also includes a filter portion, which is arranged around the outer peripheral side of the air duct portion, and a dust collecting chamber is formed between the filter portion and the air duct portion, and the filter portion has filter mesh holes, which connect the dust and gas separation chamber and the dust collecting chamber.

[0016] In this way, by arranging a filter part on the outer peripheral side of the air duct part, when the dust and gas enter the dust and gas separation chamber for separation, large particles of garbage are blocked outside the filter part and rotate and sink to the bottom of the dust cup, while small particles such as dust particles can pass through the filter mesh and enter the dust collecting chamber, thereby separating large particles of garbage from small particles of garbage, so as to avoid the problem of small particles of garbage repeatedly rotating in the dust and gas separation chamber.

[0017] In some embodiments, the air duct, the air duct portion and the dust cup are coaxially arranged.

[0018] Such an arrangement improves the dust-gas separation effect and avoids the problem of garbage getting stuck during rotation due to the small local space in the dust-gas separation chamber.

[0019] In some embodiments, the end of the filter portion facing the dust suction port has a bending portion bent toward one side of the air duct portion, and the bending portion is connected to the air duct portion to form a dust collecting table at one end of the dust collecting chamber close to the dust suction port.

[0020] In this way, by providing a dust collecting table, small particles of garbage entering the dust collecting chamber are allowed to settle on the dust collecting table, so as to facilitate the subsequent cleaning of the small particles of garbage.

[0021] In some embodiments, the air duct member further includes a first dust shield portion, one end of which is connected to an end of the filter portion facing the dust suction port, and the other end of the first dust shield portion is inclined toward a side away from the air duct portion.

[0022] With such an arrangement, the first dust blocking portion can prevent the garbage that has fallen into the bottom of the dust cup from rotating and moving upward, thereby preventing the garbage from clogging the dust outlet and improving the dust collection effect.

[0023] In some embodiments, the first dust blocking portion extends along a circumference of the filter portion.

[0024] Such a configuration can further prevent the garbage at the bottom of the dust cup from rotating, thereby improving the dust collection effect.

[0025] In some embodiments, the air duct member also includes at least two second dust shield portions, one end of each second dust shield portion is connected to one end of the filter portion facing the dust suction port, the other end of each second dust shield portion extends toward the side close to the dust suction port, and at least two second dust shield portions are arranged at intervals along the circumference of the filter portion.

[0026] With such an arrangement, the second dust blocking portion can prevent the garbage that has sunk to the bottom of the dust cup from rotating, thereby improving the dust collection effect.

[0027] In some embodiments, the second dust shield portion is at least one of a dust shield plate, a dust shield sheet, or a dust shield block.

[0028] Such arrangement has a simple structure, is easy to implement and has low process cost.

[0029] In some embodiments, the dust cup assembly also includes a HEPA filter, which is arranged above the air duct member and connected to the air duct member, the projection of the HEPA filter in the first direction covers the projection of the air duct and the dust collecting chamber in the first direction, and the end of the air duct member away from the dust suction port is sealed and connected to the dust cup and the HEPA filter in the circumferential direction.

[0030] With this arrangement, the separated garbage is filtered at the top of the dust cup by the HEPA filter element, so that large particles of garbage sink to the bottom of the dust cup and small particles of garbage sink into the dust collecting chamber, thereby achieving the purpose of improving air quality.

[0031] A second aspect of an embodiment of the present application provides a vacuum cleaner, comprising: a vacuum cleaner main unit and a dust cup assembly as provided in the above embodiment, wherein the dust cup assembly is arranged on the vacuum cleaner main unit.

[0032] The vacuum cleaner provided in the embodiment of the present application has the same beneficial effects as the dust cup assembly provided in the above-mentioned embodiment, which will not be repeated here.

[0033] In addition to the technical problems solved by the embodiments of the present application described above, the technical features that constitute the technical scheme, and the beneficial effects brought about by the technical features of these technical schemes, other technical problems that can be solved by the dust cup assembly and vacuum cleaner provided by the embodiments of the present application, other technical features included in the technical scheme, and the beneficial effects brought about by these technical features will be further described in detail in the specific implementation methods.

[0047] With the development of economy, vacuum cleaners have become more and more popular. Now vacuum cleaners have become an important tool for people to clean indoor living and working environments. In the related art, the vacuum cleaner includes a vacuum cleaner main body and a dust cup assembly connected to the vacuum cleaner. The dust cup assembly includes a dust cup and a cyclone cone. A dust suction port is provided at the bottom of the vacuum cleaner main body. A dust outlet connected to the dust suction port is provided on the bottom wall of the dust cup. The cyclone cone is located in the dust cup. The cyclone cone is a cylindrical structure with a dust suction hole on the side wall. After the vacuum cleaner is started, the dust-laden air enters the dust cup through the dust suction port. The dust-laden air rotates around the cyclone cone and separates dust and gas. However, in the related art, the garbage that sinks to the bottom of the dust cup after the dust and gas separation is easy to block the dust outlet at the bottom of the dust cup, thereby resulting in a technical problem of poor dust collection effect.

[0048] In order to solve the above problems, an embodiment of the present application provides a dust cup assembly and a vacuum cleaner, by designing a duct member, the duct member is located in the dust cup, an annular dust and gas separation chamber is formed between the outer wall of the duct member and the inner wall of the dust cup, and the duct member has an air duct connected to the dust suction port and extending along a first direction, and a dust outlet connecting the air duct and the dust and gas separation chamber is arranged at one end of the duct member close to the top of the dust cup. In this way, after the dust and gas entering the dust and gas separation chamber through the dust outlet are separated, the separated large particles of garbage sink to the bottom of the dust and gas separation chamber. Since the position of the dust outlet is higher than the bottom of the dust and gas separation chamber, the problem of garbage after dust and gas separation easily clogging the dust outlet can be avoided, thereby improving the dust suction effect and improving the utilization rate of the dust cup.

[0049] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0051] Please refer to Figures 1 to 5 As shown, the embodiment of the present application provides a dust cup assembly 100, which is suitable for use in a vacuum cleaner, for example. The dust cup assembly 100 includes a dust cup 110 and an air duct member 120; wherein the dust cup 110 has a receiving cavity, the air duct member 120 is located in the receiving cavity, and the air duct member 120 has an air duct 1211 extending along a first direction, the first direction is, for example, the height direction of the dust cup 110, for example, the air duct member 120 is vertically placed in the dust cup 110, and the height direction of the dust cup 110 is the vertical direction; that is, the first direction is the vertical direction; one end of the air duct 1211 facing the bottom wall of the dust cup 110 has a dust suction port 1212 connected to the air duct 1211, and one end of the air duct member 120 having the dust suction port 1212 penetrates the bottom wall of the dust cup 110, so that the dust suction port 1212 is connected to the outside, so that dust gas is sucked into the air duct 1211 through the dust suction port 1212.

[0052] In addition, an annular dust and gas separation chamber 130 is formed between the outer wall surface of the air duct member 120 located in the dust cup 110 and the inner wall of the dust cup 110; and the end of the air duct member 120 away from the dust suction port 1212 has a dust outlet 123, that is, the end of the air duct member 120 close to the top of the dust cup 110 has a dust outlet 123, and the dust outlet 123 connects the air duct 1211 and the dust and gas separation chamber 130. In this way, the dust and gas sucked into the air duct 1211 by the dust suction port 1212 can enter the dust and gas separation chamber 130 through the dust outlet 123. The dust and gas entering the dust and gas separation chamber 130 rotates along the dust and gas separation chamber 130 under the action of dust and gas separation, so as to realize dust and gas separation, so that large particles of garbage sink to the bottom of the dust and gas separation chamber 130.

[0053] In the embodiment of the present application, since the dust outlet 123 is arranged at one end of the air duct member 120 close to the top of the dust cup 110, the position of the dust outlet 123 is higher than the bottom of the dust and gas separation chamber 130, and the large particles of garbage after separation sink to the bottom of the dust and gas separation chamber 130, while the small particles of garbage are not easy to sink at the dust outlet 123 due to their own lighter gravity under the action of the dust and gas separation force, thereby avoiding the problem of garbage after dust and gas separation easily clogging the dust outlet 123, thereby improving the dust suction effect and improving the utilization rate of the dust cup 110.

[0054] It should be noted that Figure 2 , Figure 4 and Figure 5 The arrow in the figure represents the direction in which the dust and gas enter the dust and gas separation chamber 130 through the dust suction port and along the air duct 1211 and the dust outlet 123. Among them, the vertical downward arrow in the dust and gas separation chamber 130 represents the direction in which the separated large particles of garbage sink to the bottom of the dust and gas separation chamber 130.

[0055] It is understandable that the dust outlet 123 is arranged on the side wall of one end of the air duct member 120 close to the top of the dust cup 110, so that the dust and gas in the air duct 1211 can enter the dust and gas separation chamber 130.

[0056] In some embodiments, the cross-sectional profile of the dust cup 110 along the second direction is any shape such as a circle, a square, an ellipse, etc., wherein the second direction is perpendicular to the first direction, for example, the second direction is a horizontal direction.

[0057] For example, in Figure 1 and Figure 2 In the figure, the cross-sectional profile of the dust cup 110 along the second direction is circular, the air duct member 120 is a rotating member coaxially arranged with the dust cup 110, and the air duct 1211 and the dust cup 110 are coaxially arranged, for example. In this way, the width of the dust and gas separation chamber 130 formed along the circumferential direction is uniform to avoid the problem of dust and gas getting stuck when rotating in the dust and gas separation chamber 130, thereby improving the dust and gas separation effect.

[0058] In addition, in order to improve the efficiency of dust and gas in the air duct 1211 entering the dust and gas separation chamber 130, in some embodiments, Figure 2 , Figure 4 and Figure 5 As shown, the dust outlet 123 is inclined toward one side of the dust suction port 1212 , that is, there is an inclined angle between the dust outlet 123 and the second direction that is inclined toward the bottom of the dust cup 110 .

[0059] Thus, when the dust in the air duct 1211 enters the dust separation chamber 130 through the dust outlet 123, the downwardly inclined structure of the dust outlet 123 can give the dust at the dust outlet 123 a downwardly inclined movement direction (for example, Figure 2, Figure 4 and Figure 5 The dust outlet 123 is tilted downwardly to facilitate the dust gas to enter the dust and gas separation chamber 130 and perform dust and gas separation, thereby improving the efficiency of the dust gas entering the dust and gas separation chamber 130.

[0060] Among them, the downward inclined setting of the dust outlet 123 can be understood as that, in the outline surrounding the dust outlet 123, the outline of the dust outlet 123 toward the bottom wall side of the dust cup 110 extends obliquely downward to form a dust outlet 123 obliquely downward.

[0061] For ease of description, in the following, the outline of the dust outlet 123 refers to the outline that surrounds the dust outlet 123 and is close to one side of the bottom wall of the dust cup 110, that is, the bottom wall outline of the dust outlet 123, and the bottom wall outline of the dust outlet 123 extends obliquely downward.

[0062] In some embodiments, Figure 2 , Figure 4 and Figure 5 As shown, the contour of the dust outlet 123 is an arc-shaped structure inclined toward the dust suction port 1212, that is, the bottom wall contour of the dust outlet 123 is an arc-shaped structure extending obliquely downward; for example, the bottom wall contour of the dust outlet 123 is an arc-shaped structure, an elliptical arc-shaped structure, or a spiral arc-shaped structure, etc., as long as it is convenient for dust and gas to enter the dust and gas separation chamber 130, and no specific limitation is made here.

[0063] In an embodiment of the present application, by forming the bottom wall profile of the dust outlet 123 into an arc-shaped structure inclined toward the bottom wall of the dust cup 110, the smoothness of the dust and gas entering the dust and gas separation chamber 130 is improved, thereby further improving the efficiency of the dust and gas entering the dust and gas separation chamber 130.

[0064] In some embodiments, please refer to Figures 1 to 5 As shown, the air duct member 120 includes an air duct portion 121, which is a cylindrical structure extending along a first direction, and an air duct 1211 is formed in the air duct portion 121. Exemplarily, the air duct portion 121 is a cylindrical structure with a cross-section in a circular, elliptical, square, rectangular or other shape. Figures 1 to 5 In the embodiment, the air channel portion 121 is a cylindrical structure with a circular cross section, so that the process difficulty of the air channel portion 121 can be reduced, thereby reducing the cost.

[0065] In addition, by providing an air duct portion 121 extending along the first direction in the air duct member 120, providing an air duct 1211 in the air duct portion 121, and providing the dust outlet 123 on an end of the air duct portion 121 away from the bottom wall of the dust cup 110, the position of the dust outlet 123 can be raised so that the position of the dust outlet 123 is higher than the position where large particles of garbage settle, and the dust and gas separation chamber 130 is separated from the dust suction port 1212 and the air duct 1211, thereby avoiding the problem of garbage blocking the dust outlet 123 and the dust suction port 1212, thereby improving the dust suction effect and the utilization rate of the dust cup 110.

[0066] In some embodiments, the air duct 1211 is coaxially arranged with the air duct portion 121 , and the air duct portion 121 is coaxially arranged with the dust cup 110 , so as to improve the dust and gas separation effect and reduce the process difficulty and cost of preparing the dust cup assembly 100 .

[0067] In some embodiments, please refer to Figures 1 to 5 As shown, the air duct member 120 further includes a filter portion 122, which is disposed around the outer peripheral side of the air duct portion 121, and a dust collecting chamber 124 is formed between the filter portion 122 and the air duct portion 121, and the filter portion 122 has a filter mesh 1221, which connects the dust and gas separation chamber 130 and the dust collecting chamber 124. It can be understood that there are multiple filter meshes 1221, and the multiple filter meshes 1221 are arranged at intervals on the filter portion 122.

[0068] In the embodiment of the present application, a filter portion 122 is provided on the outer peripheral side of the air duct portion 121, so that when dust and gas enter the dust and gas separation chamber 130 for separation, large particles of garbage are blocked outside the filter portion 122 and rotate and sink to the bottom of the dust cup 110, while small particles such as dust particles can pass through the filter mesh 1221 and enter the dust collecting chamber 124, thereby separating large particles of garbage from small particles of garbage, so as to avoid the problem of small particles of garbage repeatedly rotating in the dust and gas separation chamber 130 under the force of dust and gas separation, thereby improving the dust and gas separation effect and efficiency.

[0069] In some embodiments, the filter portion 122 is, for example, a filter plate, filter sheet or other structure arranged around the outer peripheral side of the air duct portion 121, wherein the filter portion 122 has a plurality of filter mesh holes 1221 spaced apart in the circumferential direction so that small particles of dust and other garbage can enter the dust collecting chamber 124 through the filter mesh holes 1221.

[0070] In some embodiments, the filter portion 122 is coaxially arranged with the air channel portion 121 , so that the dust collecting chamber 124 formed has a uniform width along the circumference of the air channel portion 121 .

[0071] Please continue to refer to Figure 2 and Figure 3As shown, one end of the filter portion 122 facing the dust suction port 1212 has a bending portion 125 bent toward the air duct portion 121 , and the bending portion 125 is connected to the air duct portion 121 to form a dust collecting table 1251 at one end of the dust collecting chamber 124 close to the dust suction port 1212 .

[0072] It can be understood that by providing a bending portion 125 at the bottom of the filter portion 122, the bottom of the dust collecting chamber 124 is closed to form a dust collecting table 1251, so that small particles of garbage entering the dust collecting chamber 124 sink on the dust collecting table 1251, so as to facilitate the subsequent cleaning of the small particles of garbage.

[0073] Exemplarily, the bending portion 125 extends along the second direction toward one side of the air duct portion 121 , so that the formed dust collecting table 1251 extends along the second direction, so as to facilitate cleaning in the dust collecting cavity 124 .

[0074] In order to prevent the large particles of garbage that have settled in the dust-gas separation chamber 130 from rotating and moving upward in the first direction under the dust-gas separation force, in some embodiments, please continue to refer to Figures 1 to 5 As shown, the air duct member 120 further includes a first dust shield portion 126 , one end of which is connected to one end of the filter portion 122 facing the dust suction port 1212 , and the other end of the first dust shield portion 126 is inclined toward a side away from the air duct portion 121 .

[0075] In this way, the first dust blocking portion 126 can prevent the garbage that falls into the bottom of the dust cup 110 from rotating and moving upward, thereby preventing the garbage from clogging the dust outlet 123 and improving the dust collection effect.

[0076] In some embodiments, the first dust blocking portion 126 extends along the circumference of the filter portion 122, so that the garbage at the bottom of the dust cup 110 can be further prevented from rotating, thereby improving the dust collection effect.

[0077] It should be noted that there is a gap between the first dust block 126 and the inner wall of the dust cup 110 for large particles of garbage to sink to the bottom of the dust and gas separation chamber 130, and the end of the first dust block 126 away from the filter part 122 is inclined toward the bottom wall of the dust cup 110, so as to achieve the purpose of preventing large particles of garbage that have sunk to the bottom of the dust and gas separation chamber 130 from rotating upward.

[0078] Exemplarily, the inclination angle between the end of the first dust block 126 away from the filter portion 122 and the second direction is, for example, 30° to 60°, for example, the inclination angle is 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc., without specific limitation.

[0079] In addition, please continue to refer to Figures 1 to 5As shown, the air duct member 120 further includes at least two second dust blocking portions 127, which are arranged at intervals along the circumference of the filter portion 122, and one end of each second dust blocking portion 127 is connected to one end of the filter portion 122 facing the dust suction port 1212, and the other end of each second dust blocking portion 127 extends to a side close to the dust suction port 1212. In this way, the second dust blocking portion 127 can prevent the garbage that sinks to the bottom of the dust cup 110 from rotating, thereby improving the dust suction effect.

[0080] Exemplarily, the second dust blocking portion 127 is at least one of a dust blocking plate, a dust blocking sheet or a dust blocking block. In this way, the second dust blocking portion 127 has a simple structure, is easy to implement, and has a low process cost.

[0081] For example, the second dust blocking portion 127 is a structure such as a rectangular dust blocking plate, and there are four second dust blocking portions 127 , which are arranged at equal intervals along the circumferential direction of the filter portion 122 .

[0082] In some embodiments, please refer to Figure 2 As shown, the dust cup assembly 100 further includes a HEPA filter 140, which is disposed above the air duct member 120 and connected to the air duct member 120. The projection of the HEPA filter 140 in the first direction covers the projection of the air duct 1211 and the dust collecting chamber 124 in the first direction, and the end of the air duct member 120 away from the dust suction port 1212 is sealed and connected to the dust cup 110 and the HEPA filter 140 in the circumferential direction. In this way, the small particles of garbage (such as dust particles, etc.) separated from the dust and gas are first filtered by the filter part 122 for the first time, and then filtered by the HEPA filter 140 located at the top of the air duct member 120 for the second time, so that the small particles of garbage entering the dust collecting chamber 124 sink to the dust collecting table 1251 in the dust collecting chamber 124, thereby improving the air quality.

[0083] Exemplarily, the HEPA filter element 140 is, for example, a filter sponge or a filter element that can achieve a better filtering effect, which is not limited here.

[0084] In addition, the dust cup assembly 100 further includes a Hypa frame 150 , which is disposed on the top of the air duct member 120 , and the Hypa filter element 140 is fixed on the Hypa frame 150 , so as to facilitate positioning and fixing of the Hypa filter element 140 .

[0085] In order to improve the air quality, in some embodiments, please continue to refer to Figure 2As shown, a first seal 160 is provided at the connection between the outer periphery of the Hypa frame 150 and the air duct member 120, so as to improve the connection sealing between the Hypa frame 150 and the air duct member 120 through the first seal 160.

[0089] In addition, in order to facilitate the cleaning, maintenance or replacement of the duct member 120 and the dust cup 110, in some embodiments, the duct member 120 and the dust cup 110 are detachably connected. For example, the duct member 120 is disposed in the dust cup 110 and is detachably connected to the dust cup 110 by means of snap connection, buckle connection, threaded connection, etc., as long as the disassembly and assembly between the duct member 120 and the dust cup 110 is convenient.

[0090] An embodiment of the present application also provides a vacuum cleaner, including a vacuum cleaner main unit and a dust cup assembly provided in the above embodiment.

[0091] Among them, the vacuum cleaner main body includes a shell and a fan arranged in the shell. The fan can be a negative pressure fan to provide negative pressure adsorption force to the dust cup assembly through the negative pressure fan, so that the air can enter the air duct through the dust suction port and enter the dust and gas separation chamber through the dust outlet, so that the dust and gas entering the dust and gas separation chamber rotate along the dust and gas separation chamber to perform dust and gas separation. For details, please refer to the relevant technology and no specific limitation is made here.

[0092] In addition, the structure and working principle of the dust cup assembly have been introduced in detail in the above embodiments and will not be repeated here.

[0093] The embodiment of the present application provides a dust cup assembly and a vacuum cleaner, which are designed with a duct member, which is located in the dust cup, and an annular dust and gas separation chamber is formed between the outer wall of the duct member and the inner wall of the dust cup, and the duct member has an air duct connected to the dust suction port and extending along a first direction, and a dust outlet connecting the air duct and the dust and gas separation chamber is arranged at one end of the duct member close to the top of the dust cup. In this way, after the dust and gas entering the dust and gas separation chamber through the dust outlet are separated, the separated large particles of garbage sink to the bottom of the dust and gas separation chamber. Since the position of the dust outlet is higher than the bottom of the dust and gas separation chamber, the problem of garbage after dust and gas separation easily clogging the dust outlet can be avoided, thereby improving the dust suction effect and the utilization rate of the dust cup.
