Detailed Description
Example (b): as shown in fig. 1 to 4, the present invention discloses a vacuum cleaner, which comprises a vacuum cleaner main body, a locking device, and a vacuum cleaner accessory, wherein the locking device comprises a female connector 100 having a female connector cavity 102, a female connector block 120 sealingly connected to the female connector 100 and having a female connector cavity 122, a male connector 200 having a male connector cavity 202, a male connector 220 passing through the male connector cavity 202 and extending into the female connector cavity 122, a sealing member 140 disposed between the male connector 220 and the female connector block 120, and a button 300 disposed on the male connector 220 and unlocking/locking the female connector block 120.
The male connector 200 is provided with a male connector hole 204 communicated with the male connector cavity 202, the female connector block 120 is provided with a female connector block hole 124 communicated with the female connector block cavity 122, the female connector 100 is provided with a female connector hole 104 communicated with the female connector block cavity 102, wherein the buckling part 302 is in buckling connection with the female connector block hole 124, and the pressing part 304 is at least partially exposed outside through the male connector hole 204 and the female connector hole 104.
The centers of the male connection tube 220, the male joint cavity 202, the female connection cavity 122 and the female joint cavity 102 are all on the same axis. The male connector 220 has a tube body 222, a flange 224 provided outside the tube body 222, a recessed groove 226 adjacent to the flange 224 and recessed outside the tube body 222, and a pair of shaft holes 228 provided on the flange 224. The flanges 224 are integrally formed on the outer sides of three sides of the recess 226, and at least two portions of the flanges are disposed opposite to each other to form the shaft hole 228.
The button 300 includes a latching portion 302 at one end, a rotating shaft 306 at the other end and disposed corresponding to the shaft hole 228, a pressing portion 304 adjacent to the rotating shaft 306, and an elastic member 320 having one end located below the pressing portion 304 and the other end located in the recessed groove 226. Because the buckling part 302 is far away from the rotating shaft 306, the buckling is more reliable, and misoperation unlocking is prevented.
