[0024] To enable those skilled in the art to better understand the embodiments of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

[0026] See Figures 1 to 3 This utility model provides a vacuum cleaner 100, which includes a charging base station 11 and a handheld body 12. The charging base station 11 includes a top cover 111, and the top cover 111 is provided with a plug-in portion 1111. The charging base station 11 and the handheld body 12 are distributed along the height direction Y of the vacuum cleaner 100, and the handheld body 12 is detachably inserted into the plug-in portion 1111.

[0027] Thus, when the handheld device 12 is inserted into the connector 1111, the handheld device 12 can be charged by the charging base station 11 to ensure that the handheld device 12 has sufficient power to operate. The handheld device 12 can be pressed tightly against the connector 1111 under the action of gravity, which helps to improve the tightness of the connection between the handheld device 12 and the charging base station 11 and helps to reduce the escape of dust from the connection between the handheld device 12 and the charging base station 11 in the vacuum cleaner 100.

[0028] In addition, users can directly insert the handheld device 12 into the plug-in part 1111, which helps to simplify the connection between the handheld device 12 and the charging base station 11 and facilitates the connection between the handheld device 12 and the charging base station 11.

[0029] The vacuuming device 100 may have a vacuuming state (e.g., vacuuming state). Figure 5 (as shown) and self-cleaning state (as shown) Figure 1 As shown, when the vacuum cleaner 100 is in the vacuuming state, the handheld body 12 is detached from the plug-in part 1111 so that the handheld body 12 can be connected to other parts of the vacuum cleaner 100 to perform vacuuming work; when the vacuum cleaner 100 is in the self-cleaning state, the handheld body 12 is inserted into the plug-in part 1111 so that the handheld body 12 can be charged at the charging base station 11, and also facilitate the self-cleaning work of the charging base station 11 and the handheld body 12.

[0030] See Figures 2 to 4 In some embodiments, the plug-in portion 1111 includes a first plug-in interface 1112 and a second plug-in interface 1113. The first plug-in interface 1112 communicates with the second plug-in interface 1113. The first plug-in interface 1112 and the second plug-in interface 1113 are distributed along the width direction X of the vacuum cleaner 100. The handheld body 12 includes a first plug-in body 121 and a second plug-in body 122. The first plug-in body 121 is plugged into the first plug-in interface 1112, and the second plug-in body 122 is plugged into the second plug-in interface 1113.

[0031] This helps to improve the stability of the connection between the handheld device 12 and the charging base station 11, improve the tightness of the connection between the handheld device 12 and the charging base station 11, reduce the possibility of incomplete fit at the connection point due to shaking, improve the sealing of the connection between the handheld device 12 and the charging base station 11, and reduce the possibility of dust escaping from the connection point between the handheld device 12 and the charging base station 11 from the vacuum cleaner 100.

[0032] In some embodiments, the plug portion 1111 further includes a sealing body 1114, which is disposed near the second plug portion 1113 relative to the first plug portion 1112. The second plug portion 122 is provided with a dust suction port 1221, and the sealing body 1114 is inserted into the dust suction port 1221 and seals the dust suction port 1221.

[0033] Thus, the sealing body 1114 can seal the suction port 1221, and the suction port 1221 can be pressed against the sealing body 1114 under the action of gravity, which helps to improve the sealing of the connection between the handheld body 12 and the charging base station 11, and helps to reduce the situation where dust in the vacuuming device 100 escapes from the suction port 1221.

[0034] In addition, the sealing body 1114 can be directly inserted into the vacuum port 1221, which helps to simplify the connection between the sealing body 1114 and the vacuum port 1221, and facilitates the connection between the handheld body 12 and the charging base station 11.

[0035] In some embodiments, the top cover 111 includes a positioning part 1115, which is connected to the insertion part 1111 and avoids the first insertion interface 1112 and the second insertion interface 1113.

[0036] In this way, the positioning part 1115 can locate the connection position between the handheld body 12 and the plug-in part 1111, which helps to improve the accuracy of the connection position between the handheld body 12 and the plug-in part 1111, making it easier for the handheld body 12 to be accurately plugged into the plug-in part 1111, which helps to improve the efficiency of the connection between the handheld body 12 and the charging base station 11, and also enables the handheld body 12 and the plug-in part 1111 to be accurately connected, which helps to ensure the tightness of the connection between the handheld body 12 and the charging base station 11.

[0037] In addition, the positioning part 1115 avoids the first plug interface 1112 and the second plug interface 1113, so that the positioning part 1115 will not block the first plug interface 1112 and the second plug interface 1113, making it convenient for the first plug body 121 and the second plug body 122 to be plugged into the first plug interface 1112 and the second plug interface 1113 respectively.

[0038] The positioning part 1115 can be connected to the edge of the insertion part 1111 to reasonably arrange the structure of the top cover 111. This allows the positioning part 1115 to position the handheld body 12 at the connection point with the insertion part 1111, and also ensures that the positioning part 1115 does not obstruct the connection between the handheld body 12 and the insertion part 1111. The number of positioning parts 1115 can be one or more, for example, one, two, three, four, or other numbers, which can be set according to the actual situation.

[0039] In some embodiments, the top cover 111 includes a support body 1116, which protrudes from the inner wall 1117 of the top cover 111. The support body 1116 is disposed near the first insertion interface 1112 and the second insertion interface 1113, and respectively avoids the first insertion interface 1112 and the second insertion interface 1113.

[0040] Thus, when the handheld body 12 is inserted into the plug-in portion 1111, the support body 1116 can provide support force for the first plug-in body 121 and the second plug-in body 122 respectively, which helps to improve the stability of the first plug-in body 121 inserted into the first plug-in interface 1112, and helps to improve the stability of the second plug-in body 122 inserted into the second plug-in interface 1113. It also allows the support body 1116 to press against the first plug-in body 121 and the second plug-in body 122, which helps to improve the tightness of the connection between the first plug-in body 121 and the second plug-in body 122 and the charging base station 11, which helps to reduce the situation where the handheld body 12 and the charging base station 11 do not fit properly, and helps to improve the sealing of the connection between the handheld body 12 and the charging base station 11.

[0041] When the handheld body 12 is inserted into the plug-in portion 1111, the support body 1116 can be respectively arranged around the outer periphery of the first plug-in body 121 and the second plug-in body 122, which helps the support body 1116 to better provide support for the first plug-in body 121 and the second plug-in body 122, thereby better abutting against the first plug-in body 121 and the second plug-in body 122, and thus improving the tightness of the connection between the handheld body 12 and the charging base station 11.

[0042] In some embodiments, the first connector 1112 and the second connector 1113 are chamfered; or, the first connector 1112 and the second connector 1113 are rounded.

[0043] This helps reduce stress concentration at the first connector 1112 and the second connector 1113, reduces the likelihood of cracks or deformation in the connector 1111 when it is plugged into the handheld body 12, reduces the risk of damage or deformation of the connector 1111 affecting the sealing of the connection between the handheld body 12 and the charging base station 11, and facilitates the connection between the handheld body 12 and the charging base station 11, making it more convenient for users.

[0044] For example, both the first connector 1112 and the second connector 1113 are chamfered. This helps to reduce stress concentration at the first connector 1112 and the second connector 1113, helps to reduce the possibility of cracks or deformation of the connector 1111 when it is inserted into the handheld body 12, helps to reduce the possibility of damage or deformation of the connector 1111 affecting the sealing of the connection between the handheld body 12 and the charging base station 11, and also helps to reduce the occurrence of burrs at the first connector 1112 and the second connector 1113, helps to reduce the possibility of burrs scratching the handheld body 12, and also helps to reduce the possibility of burrs scratching the user, thus improving the safety of using the vacuum cleaner 100.

[0045] For example, both the first connector 1112 and the second connector 1113 have rounded corners. This helps reduce stress concentration at the first connector 1112 and the second connector 1113, reduces the likelihood of cracks or deformation of the connector 1111 when it is inserted into the handheld body 12, reduces the risk of damage or deformation of the connector 1111 affecting the sealing of the connection between the handheld body 12 and the charging base station 11, reduces the likelihood of burrs at the first connector 1112 and the second connector 1113, reduces the risk of burrs scratching the handheld body 12, reduces the risk of burrs scratching the user, improves the safety of using the vacuum cleaner 100, improves the smoothness of the first connector 1112 and the second connector 1113, and improves the aesthetics of the top cover 111.

[0046] In some embodiments, the charging base station 11 includes an electrical connector 112, which is disposed near the second connector 1113 relative to the first connector 1112. The electrical connector 112 is spaced apart from the sealing body 1114. The second connector 122 is provided with an electrical mating body 1222, and the electrical connector 112 is electrically connected to the electrical mating body 1222.

[0047] Thus, the handheld device 12 can be charged by electrically connecting to the electrical connector 112 of the charging base station 11 through the electrical coupling 1222, ensuring that the handheld device 12 has sufficient power for operation. The electrical coupling 1222 can press tightly against the electrical connector 112 under the action of gravity, which helps to improve the tightness of the electrical connection between the electrical coupling 1222 and the electrical connector 112, and helps to reduce the possibility of external water, debris and other impurities entering the connection between the electrical coupling 1222 and the electrical connector 112 and interfering with the charging of the handheld device 12. It also helps to reduce the possibility of dust in the vacuum cleaner 100 escaping from the connection between the electrical coupling 1222 and the electrical connector 112.

[0048] Please refer to the following: Figure 2 , Figure 5 and Figure 6 In some embodiments, the vacuum cleaner 100 further includes a vacuum cleaner body 13, which can be selectively connected to the charging base station 11 or the handheld body 12. When the vacuum cleaner 100 is in vacuuming mode, the vacuum cleaner body 13 is connected to the handheld body 12 so that the handheld body 12 and the vacuum cleaner body 13 can perform vacuuming work; when the vacuum cleaner 100 is in self-cleaning mode, both the handheld body 12 and the vacuum cleaner body 13 are connected to the charging base station 11, which facilitates the storage of the vacuum cleaner body 13, allows the handheld body 12 to be charged at the charging base station 11, and also helps to ensure the self-cleaning operation of the vacuum cleaner 100.

[0049] In some embodiments, the charging base station 11 is provided with a snap-fit ​​body 113, and the vacuum cleaner 13 is provided with a snap-fit ​​body 131. The snap-fit ​​body 131 is detachably connected to the snap-fit ​​body 113. When the vacuum cleaner 100 is in the vacuuming state, the vacuum cleaner 13 is connected to the handheld body 12, and the snap-fit ​​body 131 is detached from the snap-fit ​​body 113. When the vacuum cleaner 100 is in the self-cleaning state, the snap-fit ​​body 131 is connected to the snap-fit ​​body 113.

[0050] In this way, users can detach or connect the vacuum cleaner 13 to the charging base station 11 as needed, facilitating the use and storage of the vacuum cleaner 13. The method of connecting the vacuum cleaner 13 to the charging base station 11 is simple, which helps to facilitate the connection and detachment of the vacuum cleaner 13 from the charging base station 11.

[0051] The connection between the locking body 131 and the locking connector 113 can be achieved using a block and slot connection. For example, the locking body 131 can be a hook, positioned on the surface of the vacuum cleaner 13 facing the charging base station 11; the locking connector 113 can be a slot, positioned on the surface of the charging base station 11 facing the vacuum cleaner 13. The hook of the vacuum cleaner 13 is engaged in the slot of the charging base station 11, thereby achieving the connection between the locking body 131 and the locking connector 113.

[0052] In other embodiments, the connection between the card assembly 131 and the card connector 113 can also take other forms, which can be set according to the actual situation.

[0053] In some embodiments, the charging base station 11 is provided with an exhaust vent 114, and the dust collector 13 is provided with a dust collection head 132. When the dust collection device 100 is in self-cleaning mode, the exhaust vent 114 and the dust collection head 132 are opposite each other.

[0054] Thus, when the vacuum cleaner 100 is in self-cleaning mode, the airflow at the exhaust port 114 can flow through the vacuum head 132, and the vacuum body 13 can use the airflow at the exhaust port 114 to clean the vacuum head 132, thereby improving the cleanliness of the vacuum head 132.

[0055] In some embodiments, the vacuum cleaner 100 includes a moving motor 14 and a filter element 15, both of which are mounted on the handheld body 12. The moving motor 14 is movably located on the handheld body 12 and has an air inlet 141. The handheld body 12 has an air outlet 123. When the vacuum cleaner 100 is in vacuuming mode, the air inlet 141 is located inside the filter element 15 and is connected to the air outlet 123. When the vacuum cleaner 100 is in self-cleaning mode, the air inlet 141 is detached from the filter element 15, and the air inlet 141 and the air outlet 123 are not connected to each other.

[0056] In this way, the movable motor 14 can move to the corresponding position to work according to the corresponding state of the vacuum cleaner 100, which helps to enrich the functions of the vacuum cleaner 100 and help meet the user's usage needs in different situations.

[0057] For example, when the vacuum cleaner 100 is in vacuuming mode, such as Figure 6 As shown, the suction body 13 is connected to the handheld body 12. The moving motor 14 can move downward along the height direction Y of the suction device 100 and extend into the filter element 15, so that the air inlet 141 is located in the filter element 15. At this time, the moving motor 14 opens the air outlet 123, and the air inlet 141 is connected to the air outlet 123. The airflow enters the moving motor 14 through the air inlet 141 and is discharged through the air outlet 123, which generates a negative pressure in the filter element 15, thereby collecting the dust and other debris adsorbed by the suction body 13 in the filter element 15.

[0058] For example, when the vacuum cleaner 100 is in self-cleaning mode, such as Figure 2 As shown, both the handheld unit 12 and the vacuum cleaner 13 are connected to the charging base station 11. The mobile motor 14 can move upward along the height direction Y of the vacuum cleaner 100 and detach from the filter element 15, so that the air inlet 141 is detached from the filter element 15. At this time, the mobile motor 14 blocks the air outlet 123. The air inlet 141 and the air outlet 123 are not connected to each other. The air inlet 141 is directly connected to the external space. The mobile motor 14 blows air into the filter element 15 to generate positive pressure airflow to clean the dust and other debris in the filter element 15 and collect the dust and other debris in the cleaning bucket of the charging base station 11.

[0059] In summary, the vacuum cleaner 100 provided in this embodiment of the present invention includes a charging base 11 comprising a top cover 111 with a plug-in portion 1111. The charging base 11 and the handheld unit 12 are distributed along the height direction Y of the vacuum cleaner 100, and the handheld unit 12 is detachably inserted into the plug-in portion 1111. Thus, when the handheld unit 12 is inserted into the plug-in portion 1111, it can be charged through the charging base 11 to ensure sufficient power for operation. The handheld unit 12 can be pressed against the plug-in portion 1111 under gravity, which helps improve the tightness of the connection between the handheld unit 12 and the charging base 11 and helps reduce the escape of dust from the connection between the handheld unit 12 and the charging base 11 within the vacuum cleaner 100. Furthermore, the user can directly insert the handheld unit 12 into the plug-in portion 1111, which simplifies the connection method between the handheld unit 12 and the charging base 11 and facilitates the connection.
