When installing, the dust bucket 2 is placed on the base 1, so that the protrusion is inserted into the groove 13 can. Of course, after the dust bucket 2 is plugged into the base 1, other parts need to be assembled to fix the dust bucket 2, which will not be repeated here.

The bucket vacuum cleaner also includes a limit seat 3 and a conductive component 4. The limit seat 3 is arranged on the base 1. The conductive component 4 has a first end sleeved with the limit seat 3 and a second end for grounding. The dust bucket 2 is configured to be inserted into the base 1 to abut one side of the first end of the conductive component 4.

During installation, the first end of the conductive component 4 is sleeved on the limit seat 3, and the second end of the conductive component 4 is grounded. When the dust bucket 2 is plugged into the base 1, the bottom of the dust bucket 2 abuts against the bottom of the conductive component 4. The first end is easy to install. Under the action of the gravity of the dust bucket 2 or after the dust bucket 2 is fixed, it is ensured that the dust bucket 2 and the conductive component 4 are reliably pressed against each other. When in use, the static electricity on the dust bucket 2 can be discharged through the conductive component 4. Of course, in order to ensure that static electricity can be discharged, both the dust bucket 2 and the conductive component 4 are made of metal or other conductive materials, which will not be repeated here.

The conductive component 4 is a conductive chain, and the conductive chain includes a plurality of chain links connected in sequence, and at least the chain link at the first end is a ring body, which is convenient to be sleeved on the limit seat 3. Of course, the first end of the conductive element 4 may be hook-shaped.

The base 1 includes a body part 11 and a flange 12 arranged around the circumference of the body part 11. A groove 13 is formed between the flange 12 and the body part 11, and the protrusion of the dust bucket 2 can be inserted into the groove 13. The limit seat 3 is arranged on one side of the groove 13, specifically, the limit seat 3 is arranged at the edge of the groove 13, so that when the ring body is sleeved on the limit seat 3, the part of the ring body can be embedded In the groove 13, the protrusion can abut one side of the first end of the conductive component 4. The flange 12 and the body portion 11 can be integrally formed or can be detached and connected, which is not limited here. In this embodiment, the protrusion on the bottom of the dust bucket 2 may be formed by bending the wall and/or bottom plate of the dust bucket 2. The ring body can be a circular ring or an elliptical ring, which is not limited here.

Specifically, the body portion 11 has an annular shape, and the flange 12 is provided on the inner wall of the body portion 11. The flange 12 may be discontinuously distributed or continuously distributed in an annular shape. In this embodiment, the flanges 12 are intermittently distributed, in order to save material and reduce weight, and at the same time, it can fix the dust bucket 2 reasonably. In this embodiment, four sections of flanges 12 are uniformly provided on the inner wall circumference of the body portion 11, and the limit seat 3 is located on one section of the flange 12.

An avoiding groove 14 for avoiding the conductive component 4 is formed between the limit seat 3 and the flange 12 to facilitate the sleeve or hooking of the conductive component 4.

In order to ensure the stable transmission of static electricity and avoid poor contact, the chain links are all closed loops.

Further, in order to ensure that the dust bucket 2 and the conductive component 4 can be pressed tightly, an elastic member 5 is further provided, and the elastic member 5 is configured to elastically press the other side of the first end of the conductive component 4.

When installing, first set the first end of the conductive component 4 on the limit seat 3, the elastic member 5 is located on the lower side of the first end of the conductive component 4, the second end of the conductive component 4 is grounded, and then the dust bucket 2 is plugged into the base 1. When the dust bucket 2 is plugged into the base 1, the protrusion on the bottom of the dust bucket 2 will tightly abut the first end of the conductive component 4 under the action of the gravity of the dust bucket 2 to make the elastic member 5 is squeezed to produce elastic deformation. The elastic member 5 exerts an upward force on the conductive component 4 under the action of the elastic restoring force, so that the dust bucket 2 and the elastic member 5 clamp the conductive component 4 to ensure that the conductive component 4 is installed firmly and not easily Shift.

In this embodiment, the elastic member 5 is a hook. When the dust bucket 2 is inserted into the base 1, the first end of the conductive component 4 is pressed by the protrusion on the bottom of the dust bucket 2, and the conductive component 4 first The part of the ring body at the end is pressed into the hook head of the hook. At this time, the hook has an upward elastic force on the ring body to limit the position of the conductive component 4 and further ensure the installation of the conductive component 4 is stable. Of course, in other embodiments, the elastic member 5 can also be another elastic element arranged on the lower side of the conductive component 4, such as a spring. The dust bucket 2 abuts against the first end of the conductive component 4 so that the spring is compressed and elastically deformed. , I won’t repeat it here.

One end of the hook is connected with the base 1. In order to ensure the structural strength, the hook and the base 1 are integrally formed, which has a simple structure and is convenient for manufacturing.

The elastic member 5 and the limit seat 3 are as close as possible to prevent the conductive component 4 from slipping off the gap between the limit seat 3 and the elastic member 5, but there should be a gap between the limit seat 3 and the elastic member 5 to be elastic The deformation of the piece 5 provides escape space.
