[0003] However, the dust cup and separator of the existing handheld vacuum cleaner are inconvenient to remove and clean, and cannot be easily disassembled and cleaned separately. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a handheld vacuum cleaner, wherein the dust cup and the separator can be easily disassembled and cleaned separately.

[0005] Compared with the prior art, the present invention proposes a handheld vacuum cleaner, including a handheld part, a suction assembly and a battery, a vertically arranged dust bin is arranged on the front side of the handheld part, a separator is arranged in the dust bin, a connecting part for connecting a cleaning accessory is arranged circumferentially of the dust bin, the suction assembly is connected to the dust bin, the dust bin adopts a vertically penetrating cylindrical structure, an openable and closable cover is arranged at the lower end of the dust bin, the dust bin and the separator are vertically detachable and sleeved, and also includes a bracket, the bracket and the dust bin are vertically distributed up and down, the bracket is fixedly connected to the handheld part or the part extending from the handheld part to the upper side of the dust bin serves as the bracket, the lower end of the bracket is provided with a first rotating connection part and a second rotating connection part, the dust bin A third rotating connection part is provided at the upper end of the bin, and a fourth rotating connection part is provided at the upper end of the separator. The third rotating connection part and the first rotating connection part are rotatably and detachably connected as a first connection. The first connection enables the dust bin and the bracket to be rotatably and detachably connected on the lower side of the bracket. The fourth rotating connection part and the second rotating connection part are rotatably and detachably connected as a second connection, and the second connection is located on the inner side of the dust bin. The second connection enables the separator and the bracket to be rotatably and detachably connected on the lower side of the bracket. When the first connection is released, the dust bin can be removed from the bracket, and the dust bin and the separator can be separated from each other vertically through the separable socket arrangement. When the second connection is released, the separator can be removed from the bracket.

[0006] After adopting the above structure, compared with the prior art, the present invention has the following advantages:

[0007] In the present disclosure, the first connection is released, and the dust bin can be removed from the bracket. Since the dust bin adopts a vertically penetrating cylindrical structure, the dust bin and the separator can be separated from each other in the vertical direction, so the dust bin and the separator can be separated from each other in the vertical direction without affecting each other. When the second connection is released, the separator can be removed from the bracket, and the dust bin and the separator also do not affect each other. Therefore, there are three disassembly methods. The first is to disassemble the dust bin separately. After the first connection is released, the dust bin can be removed vertically from top to bottom, and the reverse direction is used. The dust bin can be reinstalled, and the separator is still connected to the bracket. The second method is to disassemble the separator separately. First, open the cover, then reach into the dust bin and rotate the separator to release the second connection. The separator can be removed vertically from top to bottom. The dust bin can be reinstalled in the reverse direction, and the dust bin is still connected to the bracket. The third method is to disassemble the dust bin first. After releasing the first connection, the dust bin can be removed vertically from top to bottom to expose the separator, and then the separator is rotated by hand (without reaching into the dust bin) to release the second connection. The separator can be removed vertically from top to bottom. In this way, the dust bin and the separator can be disassembled and cleaned separately, which is convenient for disassembly and assembly. At the same time, it is convenient for cleaning. For example, the dust bin can be removed separately for flushing without first removing the separator to flush the dust bin.

[0008] In some embodiments, a motor bracket and a support tube are also included. The motor bracket and the support tube are socket-connected and fixed to each other. The support tube is fixedly connected to the hand-held part or the part extending from the hand-held part to the upper side of the dust bin serves as the support tube, and the support tube is used to support the motor bracket; at least one of the motor bracket and the support tube serves as a bracket.

[0009] In some embodiments, a first rotating connection portion and a second rotating connection portion are sequentially arranged from outside to inside in the circumferential direction of the lower end of the support tube and / or the motor bracket.

[0010] In some embodiments, a controlled anti-rotation structure is further included, and a user controls whether the dust bin rotates relative to the bracket to release the first connection through the controlled anti-rotation structure.

[0011] In some embodiments, the controlled anti-rotation structure includes an unlocking button and a limit fitting part. The unlocking button and the limit fitting part can be lockably connected. The unlocking button has two positions, namely a locking position and an unlocking position. In the locking position, the unlocking button and the limit fitting part cooperate to lock. In the unlocking position, the unlocking button and the limit fitting part cooperate to release the cooperation to release the lock.

[0012] In some embodiments, the lower end peripheral wall of the dust bin is provided with a first protrusion or a first groove as a limiting fitting part, and the unlocking button is provided with a second protrusion. The second protrusion can be driven by the unlocking button to a locking position to block the first protrusion so that the rotation of the dust bin is restricted or inserted into the first groove so that the rotation of the dust bin is restricted. The second protrusion can be driven by the unlocking button to an unlocking position to release the blocking of the first protrusion so that the dust bin can rotate or be pulled out of the first groove so that the dust bin can rotate.

[0013] In some embodiments, a first contact is provided on the peripheral wall of the dust bin, and a second contact is provided on the front side of the hand-held part that cooperates with the peripheral wall of the dust bin. During the first connection, the first contact and the second contact are connected to each other and conductive.
