[0001] The present application relates to the technical field of vacuum cleaners, and in particular to a dust cup assembly and a vacuum cleaner. Background Art

[0002] With the development of economy, vacuum cleaners have become more and more popular.

The dust-carrying air rotates around the cyclone cone and performs dust and gas separation.

[0003] However, in the related art, when there is too much garbage, the garbage is easy to block the suction port, resulting in poor working reliability of the vacuum cleaner. Utility Model Content

[0004] 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 the dust suction port is easily blocked by excessive garbage, and improve the working reliability of the dust cup assembly and the vacuum cleaner.

[0005] In order to achieve the above objectives, the embodiments of the present application provide the following technical solutions:

[0006] A first aspect of an embodiment of the present application provides a dust cup assembly, comprising: a dust cup, an air duct member, and a cyclone cone;

[0018] In some embodiments, the outer wall surface of the air duct member is an arc surface; the inner wall surface of the dust cup is an arc surface matching the outer wall surface of the air duct member, so that the dust collecting chamber is formed into a circular dust collecting chamber.

[0025] In some embodiments, the dust shield is connected to the air guide plate.

[0026] In some embodiments, a mounting groove is provided on the air guide plate, and one side of the dust shield is installed in the mounting groove.

[0027] In some embodiments, the air duct member is detachably connected to the dust cup.

[0059] With the development of science and technology, vacuum cleaners have become more and more popular as cleaning equipment. In the related art, a vacuum cleaner includes a vacuum cleaner main unit 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 connected to the dust cup is provided at the bottom of the vacuum cleaner main unit, the cyclone cone is located in the dust cup, and the cyclone cone is a cylindrical structure with a through hole on the side wall. After the vacuum cleaner is started, the dust-laden air enters the dust cup through the dust suction port, and the dust-laden air rotates around the cyclone cone and separates dust and air. However, in the related art, when there is too much garbage, the garbage is easy to block the dust suction port, resulting in poor working reliability of the vacuum cleaner.

[0060] In order to solve the above problems, the embodiment of the present application provides a dust cup assembly and a vacuum cleaner. By designing a duct member, the duct member is arranged in the dust cup, so that a dust collecting chamber is formed between the outer wall of the duct member and the inner wall of the dust cup, the duct member has an air duct, and a dust suction port connected with the air duct is arranged at one end of the duct member, so that the dust suction port and the dust collecting chamber are independent of each other, and a cyclone cone is arranged at the end of the air duct away from the dust suction port, and a gap connecting the air duct and the dust collecting chamber is arranged on the side wall of the duct member. In this way, under the suction force of the cyclone cone, the airflow entering the air duct through the dust suction port is separated from the dust and gas by the cyclone cone, and the separated dust particles can rotate in the air duct under the centrifugal force of the cyclone cone and enter the dust collecting chamber through the gap. Since the dust collecting chamber and the dust suction port are isolated, the dust particles after the dust and gas separation can be prevented from being blocked at the dust suction port due to their own gravity, thereby improving the working reliability of the vacuum cleaner.

[0061] 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.

[0062] Figure 1 An internal schematic diagram of a cutaway position of a dust cup assembly provided in an embodiment of the present application; Figure 2 An internal schematic diagram of another cutaway position of a dust cup assembly provided in an embodiment of the present application; Figure 3 A schematic diagram of the structure of an air duct component in a dust cup assembly provided in an embodiment of the present application; Figure 4 Another schematic diagram of the structure of the air duct component in the dust cup assembly provided in an embodiment of the present application.

[0063] Please refer to Figures 1 to 4 As shown, the embodiment of the present application provides a dust cup assembly 100, including a dust cup 110, an air duct member 120 and a cyclone cone 130; the air duct member 120 is arranged in the dust cup 110, and a dust collecting chamber 111 is formed between the outer wall of the air duct member 120 and the inner wall of the dust cup 110; the air duct member 120 has an air duct 121, and one end of the air duct member 120 has a dust suction port 122 connected to the air duct 121, and the cyclone cone 130 is arranged at the end of the air duct member 120 away from the dust suction port 122, and a notch 123 connecting the air duct 121 and the dust collecting chamber 111 is provided on the side wall of the air duct member 120; the cyclone cone 130 is configured to separate dust and gas from the air flow entering the air duct 121, and the dust particles after the dust and gas separation enter the dust collecting chamber 111 through the notch 123.

[0064] It can be understood that the dust cup 110 has a accommodating cavity, the air duct member 120 is arranged in the accommodating cavity, and there is a gap between the outer wall of the air duct member 120 and the inner wall of the dust cup 110, so that the gap between the outer wall of the air duct member 120 and the inner wall of the dust cup 110 forms a dust collecting cavity 111. Exemplarily, the dust collecting cavity 111 is, for example, an annular dust collecting cavity 111, that is, the outer wall of the air duct member 120 and the inner wall of the dust cup 110 have a gap in the circumferential direction of the dust cup 110 to form an annular dust collecting cavity 111.

[0065] In some embodiments, the dust cup 110 is, for example, a cup-shaped structure with a circular cross-section.

[0066] Among them, the cyclone cone 130 is a barrel structure, and a plurality of filter holes arranged at intervals are arranged on the side wall of the cyclone cone 130. In this way, during the dust collection process, larger dust particles rotate along the air duct 121, and enter the dust collecting chamber 111 through the notch 123 on the side wall of the air duct member 120 under the action of centrifugal force, and the filtered gas is discharged through the filter holes and the air outlet in the dust cup assembly 100 to achieve dust and gas separation.

[0067] In the embodiment of the present application, the duct member 120 is provided, and the duct member 120 is provided in the dust cup 110, so that a dust collecting chamber 111 is formed between the outer wall of the duct member 120 and the inner wall of the dust cup 110, and the duct member 120 has an air duct 121, and one end of the duct member 120 is provided with a dust suction port 122 connected with the air duct 121, so that the dust suction port 122 and the dust collecting chamber 111 are independent of each other, and a cyclone cone 130 is provided at one end of the air duct 121 away from the dust suction port 122, and a notch 123 connecting the air duct 121 and the dust collecting chamber 111 is provided on the side wall of the duct member 120. In this way, under the suction force of the cyclone cone 130, the air entering the air duct 121 through the dust suction port 122 is sucked into the duct 121. The dust flows through the cyclone cone 130 for dust and gas separation. The separated dust particles can rotate in the air duct 121 under the centrifugal force of the cyclone cone 130 and enter the dust collecting chamber 111 through the gap 123. Since the dust collecting chamber 111 and the dust suction port 122 are isolated, that is, the two are independent of each other, when the garbage in the air duct 121 enters the dust collecting chamber 111 through the gap 123, if its own gravity is large, it will be deposited at the bottom of the dust collecting chamber 111, while if its own gravity is light, it will rotate along the cavity wall of the integrated cavity in the dust collecting chamber 111 under the action of centrifugal force, thereby avoiding the problem of the dust suction port 122 being blocked by a lot of garbage, thereby improving the working reliability of the dust cup assembly 100 and the vacuum cleaner.

[0068] In some embodiments, please refer to Figure 1 As shown, the notch 123 is arranged on the side wall of the air duct member 120 away from the dust suction port 122 to allow dust particles and other garbage to pass through, so that the dust particles and other garbage separated by the cyclone cone 130 can enter the dust collecting chamber 111 through the notch 123. In this way, there will be no problem of garbage accumulation and blockage in the air duct 121 and the dust suction port 122.

[0069] In addition, by providing the notch 123 on the side wall of the air duct member 120 at one end away from the dust suction port 122, the problem of excessive garbage accumulating in the dust suction port 122 and causing the dust suction port 122 to be blocked can be avoided.

[0070] In some embodiments, the notch 123 can be set on the tangent of the air duct 121. In this way, when the garbage rotates and moves in the air duct 121, it can enter the dust collecting chamber 111 through the notch 123 along the tangent direction of the air duct 121, thereby improving the smoothness of the garbage entering the dust collecting chamber 111 from the air duct 121, so as to avoid the problem of garbage accumulation in the air duct 121 causing blockage of the dust suction port 122, thereby improving the cyclone effect of the cyclone cone 130.

[0071] In some embodiments, please refer to Figure 1 and Figure 2As shown, the dust suction port 122 is arranged at the bottom of the air duct member 120, so that dust can enter the air duct 121 from the bottom of the air duct member 120, so as to facilitate the suction of dust and improve the dust suction efficiency.

[0072] It is understandable that when the dust suction port 122 is disposed at the bottom of the air duct member 120 , the notch 123 may be disposed on the side wall of the air duct member 120 close to the top, so that the notch 123 is away from the dust suction port 122 .

[0073] In other embodiments, the dust suction port 122 may also be disposed on the side wall of the air duct member 120 near the bottom, so that garbage may be prevented from clogging the dust suction port 122. The specific configuration may be adaptively adjusted according to actual needs and is not limited here.

[0074] In some embodiments, please refer to Figure 1 and Figure 2 As shown, an annular dust collecting chamber 111 is formed between the outer wall of the air duct member 120 and the inner wall of the dust cup 110, so that the garbage entering the dust collecting chamber 111 with a larger weight can be deposited at the bottom of the dust collecting chamber 111, while the garbage with a lighter weight can rotate along the circumference of the annular dust collecting chamber 111 under the centrifugal force of the cyclone cone 130, thereby avoiding the problem of garbage blocking the dust suction port 122, thereby improving the working reliability of the cyclone cone 130.

[0075] Exemplarily, the air duct member 120 is coaxially arranged with the dust cup 110, so that the dust collecting chamber 111 formed between the outer wall of the air duct member 120 and the inner wall of the dust cup 110 has a uniform gap in the circumferential direction, which can avoid the problem of garbage getting stuck during rotation.

[0076] In some embodiments, the duct member 120 is coaxially arranged with the dust cup 110, and the outer wall surface of the duct member 120 is an arc surface; the inner wall surface of the dust cup 110 is an arc surface matching the outer wall surface of the duct member 120, so that the dust collecting chamber 111 is formed into a circular dust collecting chamber 111. In this way, the smoothness of the rotation of the garbage can be improved, and the influence of the irregular contour shape of the dust cup 110 can be reduced, so that the garbage is not easily blocked in the wall of the dust collecting chamber 111, thereby improving the cyclone effect of the cyclone cone 130.

[0077] In order to improve the efficiency of moving the garbage in the air duct 121 toward the end of the gap 123, in the embodiment of the present application, please refer to Figure 3 and Figure 4As shown, an air guide plate 124 may be provided in the air duct member 120, and the air guide plate 124 may extend in a spiral shape along a first direction, so that the air duct 121 is formed into a spiral air duct extending in a spiral shape along the first direction. In this way, when receiving negative pressure wind force, the garbage may move along the spiral air duct 121 toward one end of the notch 123, so that the movement of the garbage may be guided by the air guide plate 124, thereby improving the movement efficiency of the garbage in the air duct 121 and avoiding the problem of garbage blocking the air duct 121.

[0078] It can be understood that the first direction is, for example, the extension direction of the duct member 120. For example, the duct member 120 is placed in a direction perpendicular to the ground (i.e., a vertical direction), the dust suction port 122 is arranged at the bottom of the duct member 120, and the notch 123 is arranged on the side wall of the duct member 120 near the top. In this way, the first direction is the vertical direction.

[0079] In order to prevent the garbage in the air duct 121 from flowing back through the dust suction port 122 and causing the dust suction port 122 to be blocked, in the embodiment, please refer to Figure 2 and Figure 4 As shown, a dust blocking member 140 is also included, and the dust blocking member 140 can block the garbage in the air duct 121 to prevent the garbage in the air duct 121 from flowing back.

[0080] That is to say, the dust blocking member 140 is used to prevent the garbage entering the air duct member 120 from falling along the air duct 121 toward one end of the dust suction port 122 after the motor of the vacuum cleaner stops working, thereby avoiding the problem of the dust suction port 122 being blocked by garbage.

[0081] In some embodiments, the dust shield 140 is movably disposed in the air duct 121, and the dust shield 140 is constructed to open and close the air duct 121. For example, when the fan of the vacuum cleaner is working, the dust shield 140 opens the air duct 121 along the air inlet direction under the action of suction, so that the garbage enters the air duct 121 from the dust suction port 122, and enters the dust collecting chamber 111 from the gap 123 after dust and gas separation through the cyclone cone 130; when the fan of the vacuum cleaner stops working, the dust shield 140 closes the air duct 121 to block the garbage falling in the air duct 121 through the dust shield 140, thereby avoiding the problem of garbage in the air duct 121 blocking the dust suction port 122.

[0082] In some embodiments, the dust shield 140 is movably connected to one of the air guide plate 124 and the air duct member 120; illustratively, the dust shield 140 is connected to one of the air guide plate 124 or the air duct member 120 by means of snap connection, pivot connection, etc., so that the dust shield 140 can be opened under driving force.

[0083] Exemplarily, the dust shield 140 is connected to the air guide plate 124 , so that the difficulty of disassembling and assembling the dust shield 140 can be reduced, and the disassembly and assembly cost can be reduced.

[0084] In some embodiments, please refer to Figure 3 As shown, a mounting groove 1241 is provided on the air guide plate 124 , and one side of the dust shield 140 is installed in the mounting groove 1241 so that the dust shield 140 can be opened or closed. Exemplarily, the dust shield 140 can be inserted into the mounting groove 1241 .

[0085] In addition, in order to facilitate the cleaning, maintenance or replacement of the air duct member 120 and the dust cup 110, in an embodiment of the present application, the air duct member 120 and the dust cup 110 are detachably connected. For example, the air duct member 120 is arranged in the dust cup 110 and can be 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 air duct member 120 and the dust cup 110 are convenient.

[0086] In some embodiments, the duct member 120 has a first connecting portion 125, and the dust cup 110 has a second connecting portion 112 matching the first connecting portion 125. The first connecting portion 125 and the second connecting portion 112 are connected. Exemplarily, the first connecting portion 125 is, for example, an elastic buckle, and the second connecting portion 112 is, for example, a slot; or, the first connecting portion 125 is, for example, a threaded column, and the second connecting portion 112 is, for example, a through hole through which the threaded column can pass. In this way, the threaded connecting member can be threadedly connected to the threaded column to make the duct member 120 and the dust cup 110 detachable, and the disassembly and assembly method is simple and the cost is low.

[0087] Exemplarily, a threaded column is respectively provided on the opposite sides of the air duct member 120, and correspondingly, a through hole is provided at the position corresponding to the threaded column of the dust cup 110 for the threaded connector to pass through, so that the threaded connector can be threadedly connected to the threaded column. In this way, the connection reliability between the air duct member 120 and the dust cup 110 can be improved.

[0088] The threaded connection member is, for example, a screw or the like.

[0089] In addition, in order to improve the sealing performance of the dust cup assembly 100 , in the embodiment of the present application, a seal 150 is provided at the connection between the cyclone cone 130 and the air duct member 120 , and the seal 150 seals the gap between the cyclone cone 130 and the air duct member 120 .

[0090] Exemplarily, the seal 150 is, for example, a sealing ring, which is sleeved on the cyclone cone 130 to seal the circumferential gap between the cyclone cone 130 and the air duct member 120 through the sealing ring to improve the sealing performance of the dust cup assembly 100 .

[0091] In some embodiments, please refer to Figure 1 and Figure 2 As shown, it also includes a Hypa 160 and a Hypa bracket 170. The Hypa 160 is fixed on the Hypa bracket 170 and is arranged at one end of the cyclone cone 130 away from the dust suction port 122 to filter the air at the air outlet end of the cyclone cone 130 through the Hypa 160.

[0092] 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.

[0093] 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 air can flow into the dust cup assembly through the dust suction port. For details, please refer to relevant technologies and no specific restrictions are made here.

[0094] 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.

[0095] The embodiment of the present application provides a dust cup assembly and a vacuum cleaner. By designing a duct member, the duct member is arranged in the dust cup so that a dust collecting chamber is formed between the outer wall of the duct member and the inner wall of the dust cup. The duct member has an air duct, and a dust suction port connected to the air duct is arranged at one end of the duct member, so that the dust suction port and the dust collecting chamber are independent of each other. A cyclone cone is arranged at the end of the air duct away from the dust suction port, and a gap connecting the air duct and the dust collecting chamber is arranged on the side wall of the duct member. In this way, under the suction force of the cyclone cone, the airflow entering the air duct through the dust suction port is separated from the dust and gas by the cyclone cone. The separated dust particles can rotate in the air duct under the centrifugal force of the cyclone cone and enter the dust collecting chamber through the gap. Since the dust collecting chamber and the dust suction port are isolated, the dust particles after the dust and gas separation can be prevented from being blocked at the dust suction port due to their own gravity, thereby improving the working reliability of the vacuum cleaner.
