[0037] Ginseng Figures 1 to 12 As shown, the vacuum cleaner 1 includes a head 2 and a dust collection container 3. The dust collection container 3 is used to accommodate the garbage sucked up by the vacuum cleaner 1. The head 2 includes a motor 290. The motor 290 is located inside the head 2. The head 2 is detachably mounted on the dust collection container 3 to provide suction power, so that the vacuum cleaner 1 can suck up garbage; the head 2 can be removed from the dust collection container 3 and used as a blower. The head 2 includes a movable driving member 20 and a locking member 21 that can move relative to the driving member 20. The driving member 20 is partially exposed to the The driving member 20 is outside the machine head 2, so that the driving member 20 can directly bear the force applied by the human hand; the locking member 21 is locked with the dust collecting container 3, so that the machine head 2 is locked on the dust collecting container 3; the driving member 20 can move under the force applied by the human hand and push the locking member 21 to move relative to the dust collecting container 3, so that the locking member 21 and the dust collecting container 3 are released from the locking cooperation, so that the machine head 2 can be removed from the dust collecting container 3; as the driving member 20 pushes the locking member 21, relative sliding occurs between the driving member 20 and the locking member 21.

[0038] The dust collection container 3 includes a dust collection container cover 30 and a dust collection container body 31. The machine head 2 is detachably mounted on the dust collection container cover 30. The dust collection container cover 30 is detachably mounted on the upper end of the dust collection container body 31. The dust collection container cover 30 is detachably mounted on the upper end of the dust collection container body 31 by means of buckles 33 located on the left and right sides of the dust collection container 3. The locking member 21 is locked with the dust collection container cover 30, so that the machine head 2 is locked on the dust collection container cover 30; the locking member 21 is locked with the dust collection container cover 30 by locking with the dust collection container cover 30; the driving member 20 can move under the force applied by a person's hand to push the locking member 21 to move relative to the dust collection container cover 30, so that the locking member 21 is released from the dust collection container cover 30, so that the machine head 2 can be removed from the dust collection container cover 30;

[0039] The dust container cover 30 includes a mating portion 3000, and the locking member 21 is mated with the mating portion 3000, thereby mating with the dust container cover 30; the driving member 20 can move under the force applied by a person's hand and push the locking member 21 to move relative to the mating portion 3000, so that the locking member 21 and the mating portion 3000 are released from the mating portion, so that the machine head 2 can be removed from the dust container cover 30.

[0040] The engaging portion 3000 is located at the rear side of the locking member 21. When the locking member 210 is locked with the engaging portion 3000, the engaging portion 3000 blocks the upper side of the locking member 210. The driving member 20 can move upward under the force applied by a person's hand. From another perspective, the driving member 20 can move upward under the force applied by a person's hand. As the driving member 20 moves upward, the driving member 20 pushes the locking member 21 forward, causing the locking member 21 to move forward and release the locking engagement with the engaging portion 3000. In short, the upwardly moving driving member 20 pushes the locking member 21 forward, causing the locking member 21 to release the locking engagement with the dust collection container cover 30, thereby releasing the blocking effect of the engaging portion 3000 on the upward movement of the locking member 210.

[0041] The driving member 20 includes an operating portion 200 and a pushing portion 201. The operating portion 200 is exposed outside the machine head 2; the pushing portion 201 includes an inclined first mating surface 2010, and the locking member 21 includes a locking portion 210. The locking member 21 is locked with the dust collection container cover 30 through the locking engagement of the locking portion 210 and the mating portion 3000. The locking member 21 abuts against the first mating surface 2010. A person's hand can move the driving member 20 by directly applying force to the operating portion 200. The pushing portion 201 is accompanied by The operating part 200 moves synchronously; under the force applied by the human hand to the operating part 200, the moving driving part 20 pushes the locking part 21 through the first mating surface 2010 and pushes the locking part 21 to move relative to the mating part 3000, so that the locking part 210 of the locking part 21 is unlocked from the mating part 3000, and the head 2 can be removed from the dust collection container 3 subsequently; as the driving part 20 pushes the locking part 21, the first mating surface 2010 and the locking part 21 are slidably engaged.

[0042] The first mating surface 2010 is located on the front side of the pushing portion 201, and the first mating surface 2010 is inclined toward the front and bottom; under the force applied by the human hand to the operating portion 200, the driving member 20 moves upward; the upward-moving driving member 20 pushes the locking member 21 forward through the first mating surface 2010, so that the locking portion 210 of the locking member 21 moves forward and disengages from the mating portion 3000, thereby releasing the locking engagement between the locking portion 210 and the mating portion 3000.

[0043] The locking member 21 includes an inclined second mating surface 2110, and the locking member 21 is locked with the mating portion 3000 through the locking portion 210, and the pushing portion 201 abuts against the second mating surface 2110. Under the action of the force applied by the human hand to the operating portion 200, the moving driving member 20 pushes the second mating surface 2110 through the pushing portion 201 to push the locking member 21 relative to the mating portion 3000, so that the locking portion 210 of the locking member 21 is released from the locking engagement with the mating portion 3000; as the driving member 20 pushes the locking member 21, the pushing portion 201 slides and engages with the second mating surface 2110.

[0044] The second mating surface 2110 is located on the front side of the pushing portion 201, and the second mating surface 2110 is inclined toward the front and bottom; the driving member 20 can move upward under the action of the force applied by the human hand to the operating portion 200; when the driving member 20 moves upward, the upward-moving pushing portion 201 pushes the second mating surface 2110 to push the locking member 21 forward, so that the locking portion 210 of the locking member 21 moves forward and disengages from the mating portion 3000, thereby releasing the locking engagement between the locking portion 210 and the mating portion 3000.

[0045] The latch 21 includes a receiving opening 211 into which the push portion 201 extends. The second mating surface 2110 forms a portion of the inner circumference of the receiving opening 211. This design facilitates the latch 21 to engage with the push portion 201 via the receiving opening 211. The second mating surface 2110 forms the front inner surface of the receiving opening 211, which extends obliquely upward.

[0046] The first mating surface 2010 and the second mating surface 2110 are adapted to abut against and slide relative to each other. The operating portion 200 is exposed outside the handpiece 2 and is configured to directly withstand the force exerted by a human hand to move, thereby driving the entire driving member 20 to move. The moving driving member 20 pushes the second mating surface 2110 against the first mating surface 2010, thereby pushing the locking member 21 relative to the mating portion 3000. This releases the locking portion 210 of the locking member 21 from the mating portion 3000, allowing the handpiece 2 to be removed from the dust collection container 3. As the driving member 20 pushes the locking member 21, the first mating surface 2010 and the second mating surface 2110 engage in sliding engagement. The first mating surface 2010 is parallel to the second mating surface 2110.

[0047] The driving member 20 can move upward under the force applied by a person's hand to the operating part 200. From another perspective, the operating part 200 can move upward under the force applied by a person's hand. The upward-moving driving member 20 pushes the second mating surface 2110 of the locking member 21 through the first mating surface 2010, thereby driving the locking part 210 of the locking member 21 to move forward and disengage from the mating part 3000, thereby releasing the locking part 210 from the mating part 3000.

[0048] The driving member 20 is a sliding member that can slide up and down, and the locking member 21 is a sliding member that can slide back and forth. The machine head 2 also includes a first elastic reset member 220 and a second elastic reset member 221. The first elastic reset member 220 is in a compressed state in the vertical direction and abuts the driving member 20, used to reset the driving member 20 in the vertical direction. The second elastic reset member 221 is in a compressed state in the front-to-back direction and abuts the locking member 21, used to reset the locking member 21 in the front-to-back direction. This design effectively ensures that the driving member 20 and the locking member 21 are reset in the corresponding directions. The second elastic reset member 221 is located on the front side of the locking member 21.

[0049] The driving member 20 includes a connecting portion 202, which is connected between the operating portion 200 and the pushing portion 201. The operating portion 200, the connecting portion 202, and the pushing portion 201 are sequentially connected and integrated. The head 2 also includes a handle 23, which includes a first opening 2300 corresponding to the operating portion 200. The operating portion 200 can move into the handle 23 through the first opening 2300 under the force applied by a human hand, thereby driving the locking member 21 to move to achieve unlocking. The operating portion 200 can be unlocked by a human hand. When the handle 23 and the operating part 200 are held, the user is pushed by the gripping force of the hand and moves into the handle 23 through the first opening 2300, thereby driving the locking member 21 to move; the first elastic return member 220 is located in the handle 23, and the first elastic return member 220 is used to return the driving member 20. The first elastic return member 220 is kept in a compressed state in the handle 23, and one end of the first elastic return member 220 abuts against the driving member 20. The driving member 20 can be kept in the initial position under the pressure of the first elastic return member 220 (see FIG. Figure 3 The second elastic reset member 221 is used to reset the locking member 21. The second elastic reset member 221 is kept in a compressed state in the machine head 2. One end of the second elastic reset member 221 abuts against the locking member 21. When the driving member 20 is in the initial position, the locking member 21 can maintain a locked and matched state with the dust collection container cover 30 under the pressure of the second elastic reset member 221. When the driving member 20 is in the initial position, the locking member 21 abuts against the pushing portion 201 of the driving member 20 in the initial position under the pressure of the second elastic reset member 221. Further, when the driving member 20 is in the initial position, under the pressure of the second elastic reset member 221 on the locking member 21, the second mating surface 2110 of the locking member 21 abuts against the pushing portion 201 of the driving member 20 in the initial position.

[0050] The handle 23 includes a grip 230 and a first pier 231. The grip 230 is in the shape of a rod for a person to hold. The first opening 2300 is opened at the lower side of the rear end of the grip 230. The grip 230 is located on the upper side of the machine head 2. The rear end of the grip 230 is connected to the first pier 231. The operating part 200 can move upward through the first opening 2300 and move into the grip 230 under the force applied by the human hand. The connecting part 202 is at least partially accommodated in the first pier 231. When the human hand holds the grip, the operating part 200 can move upward through the first opening 2300 and move into the grip 230. In the case of the handle 230 and the operating portion 200, the operating portion 200 moves into the handle 23 through the first opening 2300 under the gripping force of the human hand; the first pier 231 includes a front sidewall 2310, which is exposed at the front side of the first pier 231 and partially embedded between the operating portion 200 and the connecting portion 202. The operating portion 200 is located at the front side of the front sidewall 2310, and the connecting portion 202 is located at the rear side of the front sidewall 2310; the first pier 231 is in an upright position.
