The basic structure of the desktop dust collector is briefly introduced above, and in practical use, the dust collection power member 11 works, and pressure difference is formed between the inside of the dust collection chamber 3 and the outside of the dust collection chamber 3, so that internal and external pressure is formed, and the suction nozzle member 2 absorbs impurities into the dust collection chamber 3, thereby completing dust collection.

The structure of the dust suction main body 1 will be described in detail below.

As shown in fig. 4, the outermost layers of the dust collection main body 1 are a dust cap 12 on the lower side and an outer case 13 on the upper side. The two components are combined to form a relatively sealed space, which can reduce the introduction of dust or other foreign substances into the interior of the cleaner body 1.

Inside the outer casing 13 is then a mounting 14, and the mounting 14 is divided into a mounting casing 15 and a support 16, and the support 16 will house the battery 4 and the suction power member 11. And a slide switch 5 is arranged outside the supporting seat 16 and is used for switching on and off the operation of the dust suction power member 11.

As shown in fig. 4, with respect to the suction nozzle member 2, the outermost layers are a suction nozzle housing 23 located at the upper side and a lower housing 24 located at the lower side, the upper end of the suction nozzle housing 23 is engaged with the dust cap 12, and then the upper end of the lower housing 24 is engaged with the lower end of the suction nozzle housing 23.

Impurities enter the suction nozzle member 2 through the suction nozzle housing 23 after the dust suction power member 11 is operated, and the dust cap 12 forms the dust collection chamber 3 together. Then, after the use is finished, the garbage can be cleaned by only opening the connection between the suction nozzle housing 23 and the dust cap 12 to clean the garbage in the dust collecting chamber 3. As shown in fig. 6, a connection slot 231 is formed inside the suction nozzle housing 23, and a connection block 125 is formed on the surface of the dust cap 12, and the connection block 125 and the connection slot 231 are first rotated and then clamped.

The structure of the suction nozzle member 2 will be specifically described next.

As shown in fig. 6, the suction nozzle member 2 has at least:

The nozzle member 2 is further provided with a one-way valve 22 at the outlet end of the dust suction passage 21 for preventing impurities from escaping from the dust collection chamber 3 through the dust suction passage 21.

In addition, in this embodiment, the suction nozzle member 2 further includes a suction nozzle housing 23, and one end of the suction nozzle housing 23 is clamped with the outer side of the dust collection main body 1; as shown particularly in fig. 4 and 6, the nozzle housing 23 is recessed toward the dust collecting chamber 3 side and forms the dust suction passage 21.

In addition, an elastic membrane is connected to a single side at the outlet end of the dust suction channel 21, and when the dust suction power member 11 does not work, the elastic membrane covers the outlet end surface of the dust suction channel 21 to form a check valve 22.

The purpose of the single-sided connection is to allow the membrane to be folded open without breaking the connection. The purpose of designing the membrane to be elastic is to enable automatic resetting after the membrane has been flipped open. In addition, as shown in fig. 4, the membrane is horizontally covered on the outlet end surface of the dust suction channel 21, and in practical use, as shown in fig. 4, the membrane is turned upwards, so that when the dust suction power member 11 stops working, the membrane which has been turned upwards automatically covers on the outlet end surface of the dust suction channel 21 under the action of gravity, and the elasticity of the membrane is matched, so that the membrane can be better attached to the outlet end surface of the dust suction channel 21, the service life of a product is prolonged, and the effect of one-way conduction is increased.

It is to be noted that, as shown in fig. 7, there is also a passage in the center of the lower housing 24, which passage can also be regarded as the dust suction passage 21. The reason is that the channel is substantially coaxial with the hole in the center of the nozzle housing 23, as shown in fig. 4. That is, the passageway of the lower housing 24 is inside the hole in the center of the nozzle housing 23. The purpose is to achieve the introduction of impurities into the dust collecting chamber.

Also in the present embodiment, as shown in fig. 4 and 10, the obliquely arranged grating teeth can further achieve the reduction of the dust entry. Meanwhile, for children, if the grid teeth are vertically arranged, the fingers of the children may extend into the mounting seat 14 from the grid teeth, even if other flexible substances are not inserted into the mounting seat 14, the operation of the whole desktop dust collector equipment is affected, and the health and safety of the children are seriously affected.

In addition, the obliquely arranged grid teeth can prevent a user from easily seeing the structures such as the motor and the battery 4 inside the mounting seat 14, and the appearance is more attractive.

As shown in fig. 4 and 10, in the present embodiment, there are two air discharge channels, that is, a first air discharge channel 151 relatively close to the air outlet 131 and a second air discharge channel 153 relatively far from the air outlet 131;

This reduces the ingress of dust and reduces the likelihood of accidents.

The second grill teeth 154 of the second exhaust duct 153 are disposed to be inclined in a direction opposite to the direction of the outlet 131 as a whole. The relative arrangement is also preferable to view only the grill teeth from the air outlet 131 to the inside, and not to view the motor and the battery 4 inside the grill teeth. And the air current has the effect of direct air current of guide flow direction air outlet 131 after rising from the bars tooth, can guarantee to realize the ventilative effect of relatively higher heat dissipation like this. If the angle parallel to the first grid teeth 152 is adopted, the airflow is guided to the direction away from the air outlet 131 and then flows to the air outlet 131, which is not favorable for heat dissipation.

It is noted that the grating teeth are herein directed toward the first grating teeth 152 and/or the second grating teeth 154, if not specifically stated.
