[0032] In summary, due to the adoption of the above technical solution, the utility model has the following advantages compared with the prior art:

[0033] Beneficial effects:

[0034] 1. The rotary valve structure formed by the outer dust cup and the inner dust cup in the dust cup of the vacuum cleaner can realize the airflow connection of the dust collecting cavities and the filter structure in the dust cup of the vacuum cleaner composed of the first cavity and the second cavity when cleaning the surface to be cleaned, and after the vacuum cleaner host and the vacuum cleaner base station are docked and assembled, the linkage cooperates with the rotating guide groove to rotate the inner dust cup to realize the blocking of each dust collecting cavity and the corresponding filter structure, so that the garbage in the dust cup can be discharged, recovered, and the dust collecting cavity can be cleaned. The above design can avoid the reverse flow of dust, which leads to the pollution of the filter structure, and realize the dust and hair of different particle sizes intercepted by each dust collecting cavity. The garbage is discharged separately from the dust cup, avoiding the garbage collection method in which the garbage and dirt in each dust collecting chamber formed by the common vacuum cleaner dust cup structure and the connection structure of the vacuum cleaner base station are mixed and discharged from the vacuum cleaner dust cup and recycled through the vacuum cleaner base station. This causes garbage of different particle sizes to mix and the gaps to penetrate each other, resulting in clogging of the dust discharge channel and inability to discharge the vacuum cleaner dust cup and recycle it to the vacuum cleaner base station. This ensures efficient, long-term and low-cleaning frequency use of the filtering structure and efficient discharge and recovery of the dirty garbage in the vacuum cleaner dust cup, ensuring the user's clean and convenient vacuum cleaner operation and good user experience.

[0035] 2. Based on the central guiding structure of the rotating shaft, the connecting seat and the bearing for the rotation of the inner dust cup and the outer dust cup, when the inner dust cup rotates, the above structure enables the dust cup to stably rotate along the rotating shaft and the connecting seat when the vacuum cleaner dust cup is pressed into the vacuum cleaner base station, thereby ensuring that the inner dust cup rotates along the common axis with the outer dust cup, thereby reducing the radial misalignment of the inner dust cup during rotation, reducing the friction and collision between the inner dust cup and the outer dust cup during movement, and reducing the rotation resistance of the inner dust cup, so that when the vacuum cleaner host and the vacuum cleaner base station are assembled, the linkage of the inner dust cup is smoother, thereby making the switching of the connection status of the cavities and the filtering structure in the vacuum cleaner dust cup smoother and easier to operate; a first guide groove is set on the edge of the partition, and a second guide groove is set on the outer side of the bottom of the inner dust cup. The second guide groove is spliced ​​with the first guide groove, and a number of balls are set between the two. The above structure can set the spacer height of the bottom surfaces of the inner dust cup and the outer dust cup, and realize the radial positioning of the second guide groove and the first guide groove through the ball bearing, thereby ensuring the radial positioning of the inner and outer dust cups, and reducing the contact surface area of ​​the bottom surfaces of the two on the premise of low wear and collision rotation activities, so as to further reduce the rotational resistance of the two.

[0036] 3. The rotating guide groove is a spiral groove body arranged obliquely to the cross section of the jacket structure. The above structural design cooperates with the operation of pressing the dust cup structure of the vacuum cleaner into the jacket structure, so that when the inner dust cup moves down, the rotating guide groove forms a horizontal tangential force on the inner dust cup to cause it to rotate, thereby realizing the assembly of the vacuum cleaner main unit and the vacuum cleaner base station, and the synchronous switching of the connection status of each cavity inside the vacuum cleaner dust cup and the corresponding filter structure, improving the convenience of operation, and during the rotation of the inner dust cup, the dirty garbage in the second cavity is vibrated and shaken, making the subsequent garbage and dirt discharge more convenient, efficient, fast and easy to operate.

[0054] Embodiment 1:

[0055] See also Figure 1-8 The utility model provides a technical solution: a rotary valve structure of a dust cup of a vacuum cleaner, comprising a dust cup structure 2 of a vacuum cleaner arranged on a vacuum cleaner host 1 and plugged and associated with a vacuum cleaner base station 4, wherein the vacuum cleaner host 1 is plugged and associated with the vacuum cleaner base station 4, and the vacuum cleaner dust cup structure 2 comprises:

[0056] The outer dust cup 21 is divided into a plurality of first cavities 214 by a partition 213. A first connecting hole 215 is provided on the partition 213. A first filtering structure 212 is provided at the bottom of the first connecting hole 215 of the partition 213. A first dust discharge port 216 and a rotation guide hole 217 are provided on the side of the outer dust cup 21. The first dust discharge port 216 corresponds to the dust discharge channel in the vacuum cleaner base station 4.

[0057] The inner dust cup 22 is inserted into the first cavity 214 and rotatably connected to the partition 213. The bottom is provided with a second connecting hole 223 corresponding to the first connecting hole 215, and the side is provided with a second dust discharge port 224 corresponding to the first dust discharge port 216. The second connecting hole 223 and the second dust discharge port 224 are connected to the second cavity 221 in the inner dust cup 22. The second cavity 221 is provided with a second filtering structure 222. A plurality of linkage members 226 are extended outward from the outer side of the inner dust cup 22. The linkage members 226 pass through the rotating guide hole 217 and are slidably connected to the rotating guide groove 42 on the vacuum cleaner base station 4. The above-mentioned filtering structure is a cone filter and a HEPA commonly used for dust filtering in a dust cup.

[0058] like Figure 5 As shown, when cleaning the surface to be cleaned, the outer dust cup 21 and the inner dust cup 22 are locked and positioned. At this time, the first connecting hole 215 is connected to the second connecting hole 223, and the first dust exhaust port 216 and the second dust exhaust port 224 are staggered. When the vacuum motor in the vacuum cleaner host 1 is running, an airflow is formed in the dust cup structure 2 of the vacuum cleaner in the direction shown by the arrow mark in the figure. The airflow sucks the dirt and garbage on the surface to be cleaned into the dust collecting structure 3, and flows through the dust cup inlet 211, the first cavity 214, the first filter structure 212, the first connecting hole 215, the second connecting hole 223, the second cavity 221, and the second filter structure 222 in sequence to achieve air filtration and purification, and clean air is discharged from the vacuum cleaner. The dirty garbage of different particle sizes intercepted by the corresponding filter structures in the first cavity 214 and the second cavity 221 settles to the bottom for temporary storage.

[0059] In this embodiment, the first connecting hole 215 and the second connecting hole 223 are eccentrically arranged on the corresponding dust cups. After the two are connected, the axes coincide to ensure smooth and lossless airflow between different cavities, ensuring lossless suction and efficient dust collection of the vacuum cleaner.

[0060] When the dust cup 2 of the vacuum cleaner and the vacuum base station 4 are assembled and docked, the dust cup structure 2 of the vacuum cleaner is inserted into the vacuum base station 4, and the vacuum host 1 and the vacuum base station 4 are plugged and guided. The linkage 226 is guided by the rotating guide groove 42 to realize the rotation of the inner dust cup 22 along the common axis with the outer dust cup 21, so that the first connecting hole 215 and the second connecting hole 223 are staggered, the inner dust cup 22 and the outer dust cup 21 are snap-fitted and positioned, each dust collecting cavity and the corresponding filtering structure are blocked, the first dust discharge port 216 and the second dust discharge port 224 are connected, and the vacuum motor in the vacuum host 1 can be reversed or the motor in the vacuum base station 4 can be operated to realize the independent discharge of dirt and garbage in each cavity in the vacuum cup structure 2. The specific airflow inside the vacuum cleaner is as follows: Figure 6 shown.

[0061] When the vacuum cleaner main unit 1 is pulled out, the rotating guide groove 42 drives the inner dust cup 22 to rotate and reset, thereby switching the state of the vacuum cleaner dust cup, and the next stage of dust collection and cleaning operation can be carried out.

[0062] The rotary valve structure formed by the outer dust cup 21 and the inner dust cup 22 in the dust cup of the vacuum cleaner can realize the airflow connection of each dust collecting cavity and the filtering structure in the dust cup of the vacuum cleaner formed by the first cavity 214 and the second cavity 221 when cleaning the surface to be cleaned, and after the vacuum cleaner host 1 and the vacuum cleaner base station 4 are docked and assembled, the linkage 226 cooperates with the rotating guide groove 42 to rotate the inner dust cup 22 to achieve the blocking of each dust collecting cavity and the corresponding filtering structure, so that the garbage in the dust cup can be discharged, recycled, and the dust collecting cavity can be cleaned. The above design can avoid the reverse flow of dust, which may cause the filtering structure to be contaminated, and realize the different interception of each dust collecting cavity. Dust and hair of different particle sizes are discharged separately, avoiding the garbage recycling method in which the garbage and dirt in each dust collecting chamber formed by the connection structure of the common vacuum cleaner dust cup structure 2 and the vacuum cleaner base station 4 are mixed and discharged from the vacuum cleaner dust cup and recycled through the vacuum cleaner base station. This causes the garbage of different particle sizes to mix and the gaps to penetrate each other, resulting in the clogging of the dust discharge channel and the inability to discharge the vacuum cleaner dust cup and recycle it into the vacuum cleaner base station. This ensures the efficient, long-term and low-cleaning frequency use of the filtering structure and the efficient discharge and recovery of the dirty garbage in the vacuum cleaner dust cup, ensuring the user's clean and convenient vacuum cleaner operation and good user experience.

[0063] A dust collecting structure 3 is provided on the vacuum cleaner host 1, and the dust collecting structure 3 is plugged into the vacuum cleaner base station 4. A dust cup inlet 211 is provided on the side of the outer dust cup 21, and the dust cup inlet 211 is connected to the inner air duct of the dust collecting structure 3. The inner end of the dust cup inlet 211 is connected to the first filtering structure 212, and a dust cup cover 23 is provided at the bottom of the outer dust cup 21.

[0064] In this embodiment, the dust cup cover 23 is elastically hinged with a torsion spring on one side and positioned by a magnet on the other side, and is assembled at the bottom of the outer dust cup 21. Figure 5 , 6 When the vacuum cleaner main unit 1 is used for dust collection, the dust cup cover 23 is tightly closed; when the vacuum cleaner main unit 1 is mounted on the vacuum cleaner base station 4 and the garbage and dirt in the vacuum cleaner dust cup structure 2 are recovered, by pressing the switch button on the vacuum cleaner main unit 1, the vacuum motor in the vacuum cleaner main unit 1 runs in the reverse state compared with the state when dust collection is used, so that a negative pressure environment is formed in the vacuum cleaner base station 4, and the relatively high pressure environment in the dust collection structure 3 and the first cavity 214 forms a reverse airflow between them and the vacuum cleaner base station 4, so that the dust cup cover 23 is pushed open, and the garbage in the first cavity 214 of the vacuum cleaner dust cup structure 2 can be discharged and recovered.

[0065] The outer dust cup 21 is inserted and snap-fitted into position on the mounting frame 11 of the vacuum cleaner host 1, and the inner dust cup 22 is rotatably connected and assembled on the mounting frame 11. The above design ensures that the vacuum cleaner dust cup structure 2 and the vacuum cleaner host 1 are stably assembled, and realizes smooth, low-resistance rotation and movement of the inner dust cup 22 in the outer dust cup 21, thereby improving the convenience of using the rotary valve structure, and making the vacuum cleaner host 1 vacuum, dock and assemble with the vacuum cleaner base station 4, and switch the garbage collection status efficiently.

[0066] Embodiment 2:

[0067] See also Figure 2-3 5-6, based on the above embodiment 1, preferably, a connecting seat 2131 is provided in the center of the partition 213, and the bottom of the inner dust cup 22 is opened and assembled on the connecting seat 2131 through a bearing and a rotating shaft 225. The bearing is assembled in the connecting seat 2131, and the rotating shaft 225 is passed through the connecting seat 2131 and the bearing, and axial positioning is performed, and then it can be used.

[0068] When the inner dust cup 22 rotates, the above structure enables the side linkage part 226 of the inner dust cup 22 to stably rotate along the rotating shaft 225 and the connecting seat 2131 under the guidance and push of the rotating guide groove 42 when the vacuum cleaner dust cup 2 is pressed into the vacuum cleaner base station 4, thereby ensuring that the inner dust cup 22 rotates along the common axis with the outer dust cup 21, thereby reducing the radial misalignment of the inner dust cup 22 during rotation, reducing the friction and collision between the inner dust cup 22 and the outer dust cup 21 during movement, and reducing the rotation resistance of the inner dust cup 22, so that when the vacuum cleaner main unit 1 and the vacuum cleaner base station 4 are assembled, the linkage of the inner dust cup 22 is smoother, thereby making the switching of the connection state of each cavity and the filtering structure in the vacuum cleaner dust cup 2 smoother and easier to operate.

[0069] A first guide groove 2132 is disposed at the edge of the partition plate 213 , and a second guide groove 227 is disposed at the outer side of the bottom of the inner dust cup 22 . The second guide groove 227 is combined with the first guide groove 2132 , and a plurality of balls 228 are disposed therebetween.

[0070] Based on the central guiding structure of the rotating shaft 225 and the connecting seat 2131 for the rotation of the inner dust cup 22 and the outer dust cup 21, the above structure can set the spacing height of the bottom surfaces of the inner dust cup 22 and the outer dust cup 21, and realize the radial positioning of the second guide groove 227 and the first guide groove 2132 through the ball 228, thereby ensuring the radial positioning of the inner and outer dust cups, and reducing the contact surface area of ​​the bottom surfaces of the two on the premise of low wear and collision rotation activities, so as to further reduce the rotation resistance of the two.

[0071] Embodiment three:

[0072] See also Figure 6-8 On the basis of the above-mentioned embodiment 1, preferably, a jacket structure 41 is provided on the vacuum cleaner base station 4, and the jacket structure 41 is a U-shaped structure. A notch 43 which is sleeved with a guide of a corresponding structure of the vacuum cleaner host 1 is provided at a lateral opening, and the dust collecting structure 3 is inserted into the notch 43. The dust exhaust channel includes a conical channel 44 at the bottom of the jacket structure 41 and a curved channel 45 on the side. The conical channel 44 is connected to the bottom of the outer dust cup 21, and the curved channel 45 is connected to the first dust exhaust port 216.

[0073] The vacuum cleaner base station 4 is provided with a first connecting tube 441 and a second connecting tube 451 which are respectively plugged into the conical channel 44 and the curved channel 45 , and the ends of the first connecting tube 441 and the second connecting tube 451 are respectively provided with a first connecting port 442 and a second connecting port 452 for docking with the base station dust cup 46 .

[0074] The base station dust cup 46 is provided with a third connection port 461 and a fourth connection port 463 which are closely connected with the first connection port 442 and the second connection port 452 respectively. The third connection port 461 is provided with a base station dust cup inlet 462. The base station dust cup inlet 462 and the fourth connection port 463 are connected with the dust storage cavity in the base station dust cup 46. The dust storage cavity is provided with an exhaust port, and a filter is installed on the exhaust port.

[0075] like Figure 6-8As shown, when the above structure is discharging and recycling the garbage in the inner cavity of the dust cup structure 2 of the vacuum cleaner, the airflow in the second cavity 221 drives the internal dust to enter the base station dust cup 46 through the first dust discharge port 216, the second dust discharge port 224, the curved channel 45, the second connecting pipe 451, the second connecting port 452, and the fourth connecting port 463; the airflow in the first cavity 221 drives the internal dust to enter the base station dust cup 46 through the dust cup cover 23, the conical channel 44, the first connecting pipe 441, the first connecting port 442, the third connecting port 461, and the base station dust cup inlet 462, and the airflow is purified by the filter element and discharged from the vacuum cleaner base station 4 through the exhaust port, thereby realizing the independent discharge of dust of different particle sizes in each cavity of the dust cup structure 2 of the vacuum cleaner and recycling them into the base station dust cup 46 of the vacuum cleaner base station 4, ensuring efficient, stable and non-blocking operation of dust recovery, improving the efficiency of vacuum cleaner cleaning and garbage recovery, and improving user experience.

[0076] Embodiment 4:

[0077] See also Figure 1 , 4 On the basis of the above-mentioned third embodiment, preferably, a plurality of the rotating guide grooves 42 are equidistantly arranged along the inner circumference of the jacket structure 41 to ensure uniform guiding and pushing of the side surface of the inner dust cup 22 .

[0078] The rotary guide groove 42 is a spiral groove body arranged obliquely to the cross section of the jacket structure 41 .

[0079] The above-mentioned structural design cooperates with the operation of pressing the dust cup structure 2 of the vacuum cleaner into the jacket structure 41, so that when the inner dust cup 22 moves downward, the rotating guide groove 42 forms a horizontal tangential force on the inner dust cup 22 to cause it to rotate, thereby realizing the assembly of the vacuum cleaner host 1 and the vacuum cleaner base station 4, and the synchronous switching of the connection status of each cavity inside the vacuum cleaner dust cup 2 and the corresponding filtering structure, thereby improving the convenience of operation. During the rotation of the inner dust cup 22, the dirt and garbage in the second cavity 221 is vibrated and shaken, making the subsequent discharge of garbage and dirt more convenient, efficient, quick and easy to operate.

[0080] In addition, when the inner dust cup 22 is designed in multiple ways and used in the outer dust cup 21, the corresponding curved channels 45 should be staggered, independent, and non-connected, and appropriate channel merging can be performed according to the use simulation situation without causing garbage blockage, so as to reduce the size of the vacuum cleaner base station 4 and improve the structural strength of the dust discharge channel. The dust discharge structure corresponding to the first cavity 214, such as the conical channel 44 at the bottom, can be left unchanged.

[0081] At the same time, except for the corresponding positions of the inner dust cup 22 and the outer dust cup 21 close to the vacuum motor side in the vacuum cleaner host 1, the sides of the other corresponding positions of the inner dust cup 22 and the outer dust cup 21 should be provided with an air duct structure that cooperates with the plugging of the vacuum cleaner host 1 and the vacuum cleaner base station 4 or the rotation of the inner dust cup 22, so that when the vacuum cleaner host 1 takes out the vacuum cleaner base station 4, the air duct structure is not connected with the second cavity 221 in the inner dust cup 22 and the corresponding positions of the outer dust cup 21; when the vacuum cleaner host 1 is assembled on the vacuum cleaner base station 4, the air duct structure is connected with the inner dust cup 22 (except the inner dust cup 22 at the end of the outer dust cup 21 mentioned above), thereby realizing that one side of the second cavity 221 is connected to the negative pressure environment of the base station dust cup 46 of the vacuum cleaner base station 4, and one side is connected to the relatively high-pressure environment of the outside that is connected to the air duct structure, thereby realizing the formation of airflow therein, ensuring that the internal dust and garbage are fully blown out and efficient garbage recovery is achieved.

[0082] The linkage member 226 is adjusted with the linkage structure of the jacket structure 41 and the rotating guide groove 42. The jacket structure 41 adopts a structure that expands outward from the top, such as a stepped structure. The rotating guide grooves 42 are arranged at intervals in the height direction on the inner side of the jacket structure 41. The linkage member 226 adopts a design that gradually increases in length from the bottom to the top of the outer dust cup 21 and increases in length extending to the outside of the rotating guide hole 217, so that the dust cups 22 in each layer can be connected and rotated with the rotating guide groove 42 when the vacuum cleaner mainframe 1 is assembled with the vacuum cleaner base station 4, and the switching of the internal structure connection state of the dust cup of the vacuum cleaner is completed. In another embodiment, the linkage member 226 on each layer of the dust cup 22 is the same length, and the rotating guide groove 42 adopts a wavy structure, so that when the vacuum cleaner mainframe 1 is assembled with the vacuum cleaner base station 4, the dust cup 22 in the lower layer will be guided by the rotating guide groove 42 of the wavy structure to continuously rotate back and forth along the outer dust cup 21, thereby realizing the stirring of the garbage in the second cavity 221, thereby ensuring the efficient discharge and recycling of the subsequent garbage.

[0083] In summary, due to the adoption of the above technical solution, the rotary valve structure of the dust cup of a vacuum cleaner in this embodiment has the following beneficial effects compared with the prior art:

[0084] 1. The rotary valve structure formed by the outer dust cup and the inner dust cup in the dust cup of the vacuum cleaner can realize the airflow connection of the dust collecting cavities and the filter structure in the dust cup of the vacuum cleaner composed of the first cavity and the second cavity when cleaning the surface to be cleaned, and after the vacuum cleaner host and the vacuum cleaner base station are docked and assembled, the linkage cooperates with the rotating guide groove to rotate the inner dust cup to realize the blocking of each dust collecting cavity and the corresponding filter structure, so that the garbage in the dust cup can be discharged, recovered, and the dust collecting cavity can be cleaned. The above design can avoid the reverse flow of dust, which leads to the pollution of the filter structure, and realize the dust and hair of different particle sizes intercepted by each dust collecting cavity. The garbage is discharged separately from the dust cup, avoiding the garbage collection method in which the garbage and dirt in each dust collecting chamber formed by the common vacuum cleaner dust cup structure and the connection structure of the vacuum cleaner base station are mixed and discharged from the vacuum cleaner dust cup and recycled through the vacuum cleaner base station. This causes garbage of different particle sizes to mix and the gaps to penetrate each other, resulting in clogging of the dust discharge channel and inability to discharge the vacuum cleaner dust cup and recycle it to the vacuum cleaner base station. This ensures efficient, long-term and low-cleaning frequency use of the filtering structure and efficient discharge and recovery of the dirty garbage in the vacuum cleaner dust cup, ensuring the user's clean and convenient vacuum cleaner operation and good user experience.

[0085] 2. Based on the central guiding structure of the rotating shaft, the connecting seat and the bearing for the rotation of the inner dust cup and the outer dust cup, when the inner dust cup rotates, the above structure enables the dust cup to stably rotate along the rotating shaft and the connecting seat when the vacuum cleaner dust cup is pressed into the vacuum cleaner base station, thereby ensuring that the inner dust cup rotates along the common axis with the outer dust cup, thereby reducing the radial misalignment of the inner dust cup during rotation, reducing the friction and collision between the inner dust cup and the outer dust cup during movement, and reducing the rotation resistance of the inner dust cup, so that when the vacuum cleaner host and the vacuum cleaner base station are assembled, the linkage of the inner dust cup is smoother, thereby making the switching of the connection status of the cavities and the filtering structure in the vacuum cleaner dust cup smoother and easier to operate; a first guide groove is set on the edge of the partition, and a second guide groove is set on the outer side of the bottom of the inner dust cup. The second guide groove is spliced ​​with the first guide groove, and a number of balls are set between the two. The above structure can set the spacer height of the bottom surfaces of the inner dust cup and the outer dust cup, and realize the radial positioning of the second guide groove and the first guide groove through the ball bearing, thereby ensuring the radial positioning of the inner and outer dust cups, and reducing the contact surface area of ​​the bottom surfaces of the two on the premise of low wear and collision rotation activities, so as to further reduce the rotational resistance of the two.

[0086] 3. The rotating guide groove is a spiral groove body arranged obliquely to the cross section of the jacket structure. The above structural design cooperates with the operation of pressing the dust cup structure of the vacuum cleaner into the jacket structure, so that when the inner dust cup moves down, the rotating guide groove forms a horizontal tangential force on the inner dust cup to cause it to rotate, thereby realizing the assembly of the vacuum cleaner main unit and the vacuum cleaner base station, and the synchronous switching of the connection status of each cavity inside the vacuum cleaner dust cup and the corresponding filter structure, improving the convenience of operation, and during the rotation of the inner dust cup, the dirty garbage in the second cavity is vibrated and shaken, making the subsequent garbage and dirt discharge more convenient, efficient, fast and easy to operate.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
