Specifically, the air outlet is a lateral through hole, and the lateral through hole is a plurality of. In the multifunctional tabletop vacuum cleaner of this embodiment, when in operation, the air flow (and noise) in the impeller cavity 101 flows to the outside of the housing 100 through the first flow guide gap, the second flow guide gap, and the lateral through hole.

And, as can be seen from fig. 7 and 8, the first and second flow guiding

cross plates

51 and 53 are parallel to each other, and the first and second

flow guiding sidewalls

52 and 54 are parallel to each other; the second flow guide part is positioned on the upper side of the first flow guide part; in addition, the first flow guide part and the second flow guide part are horizontally arranged in an L shape in the direction of a vertical section.

Here, it should be noted that, in the conventional multifunctional tabletop dust collector, an air inlet and an air outlet are provided, and during the working process, the rotation of the impeller 30 generates noise, which is directly transmitted from the air outlet along with the noise, and especially, after a filtering sponge or other filtering structures are added, the working power of the impeller 30 needs to be correspondingly increased, so that the interference of the noise to the user is increased; in the multifunctional desktop dust collector of the embodiment, the diversion cover 50 is additionally arranged to guide the transmission of the air flow (and the sound), the traditional straight-through channel is changed into the diversion channel with a plurality of inflection points, the transmission mode of the air flow (the sound) is changed, and the noise pollution is reduced.

In the preferred embodiment of the present invention, the lower side of the casing 100 is detachably connected to the pet brush 200 at the air inlet, the pet brush 200 includes a plurality of vertically arranged brush posts, and the bottom of the brush posts is arranged to be gradually higher from the center of the pet brush 200 to the outer periphery. Through setting up pet brush 200 for this embodiment is at most the function desktop dust catcher can also remove dust to the pet when the desktop dust absorption, and through the specific design to the brush post, its appearance radian that accords with general pet more does benefit to the dust removal to the pet.

In the preferred embodiment of the present invention, the flat-nose brush 300 is detachably connected to the lower side of the casing 100 at the air inlet. Therefore, when aiming at some corners (dead angles), the flat-nozzle brush 300 can be connected to suck dust at the corners, and the dust suction device is simple and effective. The flat-nose brush 300 is a common part and will not be described herein. Of course, the pet brush 200 and the flat mouth brush 300 are provided with a relief hole corresponding to the air inlet.

As an optimal scheme, can electric connection have lamp pearl and inductive switch 11 on the main control board 10, inductive switch 11 control the opening and close of lamp pearl. Specifically, the position of the shell 100 corresponding to the lamp bead is designed as a light-transmitting shell 100; or, the lamp bead is arranged on the upper side of the shell 100, and the upper side of the lamp bead is covered with the light-transmitting cover.

The inductive switch 11 can be a human body inductive switch or a photosensitive inductive switch or a combination of the human body inductive switch and the photosensitive inductive switch, and when the lamp is used, the inductive switch 11 determines whether to turn on the lamp bead or not according to the illumination condition and the distance between the human body and the environment, so that illumination is performed.

The following further describes the working principle of the multi-functional tabletop dust collector of the present embodiment in general:

after the driving motor 20 is started, the impeller 30 rotates, negative pressure is formed on the air outlet side of the impeller 30, external dust (including air flow) enters the casing 100 from an air inlet at the lower end of the casing 100, is blocked by the filtering component 40, and falls on a dust collecting cover 102 of the casing 100 (the casing 100 comprises a dust collecting cover 102 detachably connected to the air inlet); while the air flow still passes through the filter assembly 40 and enters the impeller cavity 101 and exits the housing through the first flow guide gap, the second flow guide gap, and the lateral through-holes (the sound also exits the housing through the first flow guide gap, the second flow guide gap, and the lateral through-holes).

Here, it is to be added that: referring to fig. 5 and 6, the first through hole 411 and the second through hole 421 are respectively disposed on the peripheral sides of the first clamping plate 41 and the second clamping plate 42; namely: the center of the first clamping plate 41 is a base (the position of the base is opposite to the air inlet), which is not penetrated, and the first through hole 411 is arranged on the periphery of the base; thus, when air is supplied, the air inlet brings dust (particles) into the housing 100 by the air flow, and further, the first clamping plate 41 guides the air flow into the impeller cavity 101 from the first through hole 411 on the periphery of the base, and the dust (particles) drops on the dust collection cover 102 due to the blocking of the first clamping plate 41 and the second clamping plate 42. Meanwhile, the dust collection cover 102 has an avoiding hole corresponding to the air inlet, a stopping portion extends upwards from the avoiding hole, and dust (particles) is limited by the stopping portion and the peripheral side wall of the dust collection cover 102.

Referring to fig. 9 to 11, a multifunctional tabletop dust collector according to a second embodiment of the present invention is substantially the same as the first embodiment, except that:

the guide cover is provided with a third guide plate 61 and a fourth guide plate 62 which are arranged at an upper-lower interval, a first guide gap is formed between the third guide plate 61 and the impeller cavity 101, a second guide gap is formed between the fourth guide plate 62 and the third guide plate 61, and the second guide gap is communicated with the air outlet. In the second embodiment of the multifunctional table-top vacuum cleaner, when the multifunctional table-top vacuum cleaner is in operation, the air flow (and noise) in the impeller cavity 101 flows to the outside of the housing 100 through the first flow guide gap, the second flow guide gap and the lateral through hole.

Compared with the multifunctional table top dust collector in the first embodiment, the multifunctional table top dust collector in the second embodiment has the advantages that the air outlet is faster, the dust collection efficiency is higher, and the working pressure of the driving motor 20 is lower; and the design of the flow guide cover is simpler and is convenient to manufacture.

The above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. But rather, obvious variations and modifications may be made without departing from the spirit of the invention.
