[0039] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

[0040] Please also read Figures 1 to 6 The embodiment of the present invention discloses a vacuum cleaner, including a base station 10, a vacuum cleaner body 20 and a sealing structure 102. The vacuum cleaner body 20 includes a detachably connected dust suction structure 1 and a dust cup structure 2. The dust cup structure 2 has a dust suction port 211 connected to the dust suction structure 1. The sealing structure 102 is arranged on the base station 10 and / or the dust cup structure 2. The dust cup structure 2 can be plugged into the base station 10 after being removed from the dust suction structure 1, so that the sealing structure 102 closes the dust suction port 211. With such a design, by arranging the sealing structure 102 on the base station 10 and / or the dust cup structure 2, the sealing structure 102 closes the dust suction port 211, so that the dust suction port 211 has a better sealing effect after the dust cup structure 2 is removed from the dust suction structure 1, thereby effectively preventing dust leakage.

[0041] Among them, the sealing structure 102 is arranged on the base station 10 and / or the dust cup structure 2 specifically includes: the sealing structure 102 is arranged on the base station 10, the sealing structure 102 is arranged on the dust cup structure 2, and the sealing structure 102 is arranged on the base station 10 and the dust cup structure 2.

[0042] As an optional embodiment, the sealing structure 102 is a sealing ring, which is sleeved on the outer periphery of the dust cup structure 2 corresponding to the dust suction port 211. When the dust cup structure 2 is plugged into the base station 10, the sealing ring abuts against the inner wall surface of the base station 10 to close the dust suction port 211.

[0043] As another optional embodiment, the sealing structure 102 is a protrusion provided on the base station 10, and when the dust cup structure 2 is plugged into the base station 10, the protrusion is at least partially inserted into the dust suction port 211 to close the dust suction port 211. Preferably, when the dust cup structure 2 is plugged into the base station 10, the protrusion is fully inserted into the dust suction port 211.

[0044] It is understandable that the sealing structure 102 can also be a sealing groove provided in the base station 10 or other sealing structures provided on the dust cup structure 2, which is not limited here.

[0045] Furthermore, the base station 10 is provided with a plug-in slot 101 having a first opening, the sealing structure 102 is provided in the plug-in slot 101, and the dust cup structure 2 is plugged into the plug-in slot 101 from the first opening of the plug-in slot 101, so that the sealing structure 102 is plugged into the dust suction port 211. With such a design, since the dust cup structure 2 is plugged into the plug-in slot 101, the sealing property at the dust suction port 211 can be further improved. In addition, if dust falls off during the process of inserting the sealing structure 102 into the dust suction port 211, the dust can also fall into the plug-in slot 101, thereby preventing the dust from falling into the external environment during the process of inserting the sealing structure 102 into the dust suction port 211.

[0046] Preferably, the first opening of the plug-in slot 101 is arranged upward, so that the dust cup structure 2 is plugged into the plug-in slot 101 from top to bottom. Such an arrangement can better plug the base station 10 into the base station 10 compared to the traditional design of opening from the side. In addition, the sealing performance of the contact between the dust cup structure 2 and the base station 10 is also better.

[0047] In some embodiments, the base station 10 is further provided with a first charging interface 103, and the dust cup structure 2 is provided with a second charging interface 212. When the dust cup structure 2 is plugged into the base station 10, the second charging interface 212 is electrically connected to the first charging interface 103, so that the base station 10 charges the dust cup structure 2. With such a design, the dust cup structure 2 can be plugged into the base station 10 to not only achieve self-cleaning, but also achieve charging.

[0048] The first charging interface 103 is also disposed in the plug slot 101 and is spaced apart from the sealing structure 102 .

[0049] Specifically, the first charging interface 103 is a charging pin, and the second charging interface 212 is a charging port that matches the charging pin. This design facilitates the electrical connection between the first charging interface 103 and the second charging interface 212. It is understandable that the first charging interface 103 and the second charging interface 212 can also be non-contact charging interface components that are compatible with each other, which is not limited here.

[0050] In some embodiments, in order to realize the dust suction and self-cleaning functions, the dust cup structure 2 includes a dust cup body 21, a motor assembly 22 and a filter element 23. The dust cup body 21 is detachably connected to the dust suction structure 1, and the dust suction port 211 is arranged on the dust cup body 21. The motor assembly 22 and the filter element 23 are both arranged on the dust cup body 21. The dust cup body 21 is provided with a first air inlet 213 and a first air outlet 214 which are connected to the external environment, and the motor assembly 22 is provided with a second air inlet 221. When the dust cup structure 2 is in the dust suction state, under the exhaust action of the motor assembly 22 (the flow direction of the wind is as shown in FIG. 2 ), the dust cup body 21 is provided with a first air inlet 213 and a first air outlet 214 which are connected to the external environment, and the motor assembly 22 is provided with a second air inlet 221. Figure 3As shown by the arrow in the middle, a dust suction duct is formed from the filter element 23, the second air inlet 221 and the first air outlet 214. At this time, negative pressure is generated in the filter element 23, so that dust and garbage are collected in the dust cup structure 2; when the dust cup structure 2 is in the self-cleaning state, the motor assembly 22 blows air toward the filter element 23 (the flow direction of the wind is as shown in FIG. Figure 6 As shown by the middle arrow, a self-cleaning air duct is formed from the first air inlet 213, the second air inlet 221 and the filter element 23, a positive pressure is generated in the filter element 23, and the dust in the filter element 23 is discharged, thereby achieving self-cleaning.

[0051] Furthermore, in order to better form the above-mentioned air duct, the motor assembly 22 is movably arranged in the dust cup body 21. When the dust cup structure 2 is in a dust suction state, the motor assembly 22 can move in a direction toward the filter element 23 to open the first exhaust port 214 and insert the second air inlet 221 into the filter element 23. When the dust cup structure 2 is in a self-cleaning state, the motor assembly 22 can move in a direction away from the filter element 23 to close the first exhaust port 214 and the second air inlet 221 is separated from the filter element 23 to be connected with the first air inlet 213.

[0052] In some embodiments, in order to drive the motor assembly 22 to move, a second opening is provided on the dust cup body 21, and the motor assembly 22 is partially exposed from the second opening of the dust cup body 21, and is used to move in the direction toward the filter element 23 under the pressure of external force. In order to reset the motor assembly 22, the dust cup structure 2 also includes a first elastic member 24, one end of the first elastic member 24 abuts against the inner wall of the dust cup body 21 and the other end abuts against the motor assembly 22, and is used to push the motor assembly 22 to move in the direction away from the filter element 23 when the external force is removed. It can be understood that in other embodiments, a power assembly can also be provided to drive the motor assembly to move, which is not limited here.

[0053] Furthermore, in order to keep the motor assembly 22 in the active position when the dust cup structure 2 is in the dust suction state, a pin is provided on the base station 10, and a first limit block 215 and a second elastic member are also provided on the dust cup body 21. A second limit block 222 is provided on the motor assembly 22. When the dust cup structure 2 is in the dust suction state, the first limit block 215 moves to cooperate with the second limit block 222 under the action of the second elastic member to keep the motor assembly 22 in the current position. When the dust cup structure 2 is in the self-cleaning state, the first limit block 215 moves to disengage from the second limit block 222 under the action of the pin, and the motor assembly 22 moves and resets under the action of the first elastic member 24.

[0054] In some embodiments, in order to allow the dust in the dust cup structure 2 to enter the dust suction structure 1 during self-cleaning, a pin is provided on the base station 10, and a third opening and a movable cover 216 are provided on the dust cup body 21; when the dust cup structure 2 is in the dust suction state, the movable cover 216 closes the third opening; when the dust cup structure 2 is in the self-cleaning state, the movable cover 216 moves to open the third opening under the action of the pin, so that the dust cup body 21 is connected to the base station 10, so as to blow the dust in the dust cup body 21 into the base station 10.

[0055] In some embodiments, the dust cup body 21 is further provided with an elastic baffle 217. When the dust cup structure 2 is in the dust suction state, the elastic baffle 217 is opened under the exhaust action of the motor assembly 22. When the dust cup structure 2 is in the self-cleaning state, the elastic baffle 217 is closed under the blowing action of the motor assembly 22. With such a design, the elastic baffle 217 can prevent the dust collected in the dust cup structure 2 from leaking out from the dust suction port 211 when the dust cup structure 2 is removed from the dust suction structure 1.

[0056] In some embodiments, the base station 10 is further provided with a first fixing portion 104, and the dust collecting structure 1 is provided with a second fixing portion 11, and the dust collecting structure 1 is detachably fixed to the base station 10 through the cooperation between the second fixing portion 11 and the first fixing portion 104. With such a design, after the dust cup structure 2 and the dust collecting structure 1 are disassembled, the dust cup structure 2 can be plugged into the base station 10, and the dust collecting structure 1 can be fixed to the base station 10, so as to facilitate the storage of the dust collecting structure 1 and the dust cup structure 2.

[0057] Furthermore, the first fixing part 104 is a hanging part, and the second fixing part 11 is a hook, and the hook is hung on the hanging part. With such a design, the structure is simple.

[0058] Preferably, a dust suction head 12 is provided on the dust suction structure 1, and a second air outlet 105 is also provided on the base station 10. When the dust suction structure 1 is fixed to the base station 10, the second air outlet 105 blows air toward the dust suction head 12. With such a design, it is possible to prevent uncleaned dust in the wind discharged from the base station 10 from being discharged into the external environment.

[0059] A vacuum cleaner provided by the present invention includes a base station 10, a vacuum cleaner body 20 and a sealing structure 102. The vacuum cleaner body 20 includes a detachably connected dust suction structure 1 and a dust cup structure 2. The dust cup structure 2 has a dust suction port 211 connected to the dust suction structure 1. The sealing structure 102 is arranged on the base station 10 and / or the dust cup structure 2. The dust cup structure 2 can be plugged into the base station 10 after being disassembled from the dust suction structure 1, so that the sealing structure 102 closes the dust suction port 211. With such a design, by arranging the sealing structure 102 on the base station 10 and / or the dust cup structure 2, the sealing structure 102 closes the dust suction port 211, so that the dust suction port 211 has a better sealing effect after the dust cup structure 2 is disassembled from the dust suction structure 1, thereby effectively preventing dust leakage.
