the vacuum cleaner further comprises a support base 7 extending horizontally at the bottom of the body 1, wherein a handle 8 for holding is arranged between the middle part of the support base 7 and the body 1.

In this embodiment, the vacuum cleaner includes a main body 1, wherein a dust suction fan 2, a filter 3 and a dust cup 4 are disposed in the main body 1, an air inlet 5 and an air outlet 6 are disposed on a side portion of the main body 1, and the air inlet 5 and the air outlet 6 are disposed opposite to each other. The dust suction fan 2 includes a dust suction motor and an impeller provided coaxially with the dust suction motor. The dust suction motor is used for driving the impeller to rotate at a high speed, and air negative pressure is generated in the body 1 and used for sucking dust. Specifically, the dust collection fan 2 includes an air suction opening and an air outlet, the air suction opening is arranged in the axial direction of the dust collection fan 2, and the air outlet is arranged in the radial direction of the dust collection fan 2.

In one example, the dust cup 4 may be installed outside the filter 3, and the filter 3 may be disposed around the dust suction fan 2, the air inlet 5 is communicated with the inside of the dust cup 4, and the air outlet 6 is communicated with the air outlet of the dust suction fan 2. Here, the communication may be understood as a through air passage. The filter 3 is used for filtering dirty air entering the dust cup 4 from the air inlet 5, wherein the dirty air in the dirty air is collected in the dust cup 4, and the air filtered by the filter 3 flows to the air suction opening of the dust collection fan 2 and then flows to the outside of the air outlet 6 through the air outlet of the dust collection fan 2.

In one example, in order to facilitate the placement and the handling of the vacuum cleaner, the vacuum cleaner may further include a support base 7 horizontally extending at the bottom of the body 1, and in particular, the support base 7 may be located right below the air outlet 6. The bottom of the supporting base 7 is a plane and is in the same plane with the bottom of the body 1, so that when the dust collector is placed, the contact area between the dust collector and the placed platform is increased, and the stability of the dust collector when the dust collector is placed is improved. And a handle 8 for hand holding is provided between the middle portion of the support base 7 and the body 1. The handle 8 is convenient to hold in hand, and is more convenient to operate during cleaning.

Referring to fig. 2, in an alternative embodiment, a filter cotton 9 is disposed around a suction opening of the dust suction fan 2, and the filter cotton 9 is used for secondarily filtering the air filtered by the filter 3.

The top of the filter cotton 9 is provided with a buckle cover 10 connected with the body 1.

In this embodiment, in order to prevent a small amount of dust contained in the air filtered by the filter 3 from affecting the operation of the dust suction fan 2, in an example, the filter cotton 9 may be disposed around the air suction opening of the dust suction fan 2, and the filter cotton 9 is used to filter the air filtered by the filter 3 for a second time. Wherein, the filter cotton 9 can be ring-shaped, and a diversion channel for air to flow to the suction inlet of the dust collection fan 2 is reserved at the center of the filter cotton 9. The arrangement of the filter cotton 9 can prolong the service life of the dust absorption fan 2. The product performance of the dust collector is optimized.

Considering the limited filtration life of the filter cotton 9, it needs to be replaced regularly. As an optional embodiment, a through hole may be formed in the body 1 at the top of the filter cotton 9, and a buckle cover 10 connected to the body 1 is installed on the through hole, wherein the buckle cover 10 may be fastened and fixed with the body 1, and when the filter cotton 9 needs to be replaced, the buckle cover 10 is opened to take out the filter cotton 9.

In an alternative embodiment, the air inlet 5 is horizontally connected with a connecting part 11 for detachably connecting with a suction nozzle. Specifically, according to the difference of the cleaning positions, the suction nozzles may include various types such as different diameters and different lengths, and the connection portion 11 may be connected to different types of suction nozzles matched with the vacuum cleaner, so as to facilitate cleaning of different cleaning positions. Meanwhile, when cleaning is completed, the suction nozzle can be conveniently detached from the coupling portion 11, and the structure thereof can be miniaturized and is convenient to store.

Referring to fig. 2, in an alternative embodiment, a battery pack 12 for powering the suction fan 2 is mounted in the support base 7. The storage battery pack 12 may include a plurality of storage batteries, and the storage battery pack 12 may be configured to supply power to maintain the cleaning operation through the storage battery pack 12 without charging a charging wire. Therefore, when the dust collector is used for cleaning, the limitation of a charging wire and the corresponding socket position can be avoided, and the product applicability of the dust collector is improved.

In an alternative embodiment, because the structure in the body 1 is more, the user can take the handle 8 for cleaning, and the user can take the handle to maintain balance with more effort, therefore, the air outlet 6 is horizontally extended and forms an extended portion 13, the air passing through the air outlet 6 is exhausted at the tail end of the extended portion 13, and the end of the extended portion 13 far away from the body 1 is called the tail end. Wherein the handle 8 is located between a middle portion of the support base 7 and a middle portion of the extension 13. Specifically, the length of the support base 7 extending horizontally from the body 1 is greater than the length of the extension 13 extending horizontally from the body 1. Therefore, the handle 8 is far away from the body 1, the weight distribution of the whole dust collector is more uniform, and the use comfort of a user can be improved.

Referring to fig. 1 and 2, in an alternative embodiment, a control switch 14 is further disposed on the handle 8, and the control switch 14 is electrically connected to the dust collection fan 2, wherein the control switch 14 may be connected in series in a power supply circuit of the dust collection fan 2 to control the dust collection fan 2.
