When the dust collector works, the lower shell 1 is attached to an object to be cleaned to remove mites and suck dust. Fig. 2 is a schematic structural view of another angle of the vacuum cleaner provided in the embodiment of the present application, and as shown in fig. 1 and 2, the lower housing 1 includes a main body 11 and an air inlet 12, where the main body 11 includes a bottom surface 111 for being attached to an object to be cleaned. When the vacuum cleaner 100 is operated, the motor generates a negative pressure so that the bottom surface 111 can be attached to an object to be cleaned.

The air inlet part 12 is symmetrically distributed along the central line of the dust collector 100, the air inlet part 12 comprises a first step surface 121 and a convex part 122 arranged on the first step surface 121, and the first step surface 121 is upwards concave along the bottom surface 111; the boss 122 protrudes downward along the first step surface 121.

It can be understood that the first step surface 121 is recessed upwards along the bottom surface 111, so that the vacuum cleaner 100 is in a state of being placed on an object to be cleaned, such as a bed sheet, and at this time, the bottom surface 111 is attached to the bed sheet, but the first step surface 121 is not attached to the bed sheet. The protrusion 122 protrudes downward along the first step surface 121, that is, the protrusion 122 protrudes in a direction of the first step surface 121 toward the sheet.

When the vacuum cleaner 100 stays on the object to be cleaned, the protrusion 122 contacts the object to be cleaned before the first step surface 121, and when the object to be cleaned is adsorbed to the first step surface 121, the protrusion 122 can jack the object to be cleaned, so that the airflow bypasses the protrusion 122 and flows to the inside of the vacuum cleaner 100, the air inlet blockage caused by the attachment of the object to be cleaned and the first step surface 121 is prevented, the dust collection quality is improved, and the user experience is improved.

As a specific embodiment, the protrusion 122 includes a plurality of first protrusions 122b, and the first protrusions 122b may be integrally formed with the first step surface 121. The first projection 122b may be provided at a position of the first step surface 121 near the opening end of the air intake portion 12, or may be provided at another position of the first step surface 121.

In one embodiment, the first bump 122b does not protrude from the bottom surface 111. Thus, when the cleaner 100 is placed on an object to be cleaned, the cleaner 100 can be smoothly attached to the object to be cleaned.

Fig. 3 is a front view of a vacuum cleaner according to an embodiment of the present disclosure, fig. 4 is a schematic structural view of a lower housing of the vacuum cleaner according to an embodiment of the present disclosure, and fig. 5 is a partial enlarged view of fig. 4, as shown in fig. 3 to 5, as a specific embodiment, the lower housing 1 may include a slap block 125, and the slap block 125 is connected to the first step surface 121. When the vacuum cleaner 100 is in operation, the hitting block 125 can vibrate to hit the object to be cleaned. The first projection 122b may be disposed around the slap block 125. In this embodiment, there are two slapping blocks 125, which are symmetrical about the center line of the vacuum cleaner 100.

In this embodiment, the protrusion 122 includes a plurality of second protrusions 122a, and the second protrusions 122a are disposed on the slapping block 125. The second protrusions 122a may be integrally formed with the slap block 125, the plurality of second protrusions 122a may be substantially hemispherical, and the spherical radii of the respective second protrusions 122a may or may not be uniform. In this embodiment, the radius of the sphere of the second protrusion 122a located at the middle of the slapping block 125 is larger, and the radius of the sphere of the second protrusion 122a located at the peripheral edge is smaller.

When the vacuum cleaner 100 is in operation, the first protrusion 122b, the slapping block 125 and the second protrusion 122a arranged on the slapping block 125 can jack up the object to be cleaned, and the airflow bypasses the first protrusion 122b and the second protrusion 122a and enters the vacuum cleaner 100, so that the position of the first step surface 121 is prevented from being blocked.

The protrusion 122 protrudes downward along the first step surface 121, and the protrusion 122 may or may not protrude beyond the bottom surface 111. In the embodiment shown in fig. 3, the protrusion 122 includes a second protrusion 122a, and the second protrusion 122a protrudes from the bottom surface 111.

In a specific embodiment, the range of the dimension b of the second protrusion 122a protruding from the bottom surface 111 is 0< b ≦ 2mm, and preferably 1mm, so that the position of the first step surface 121 is prevented from being blocked, and the overall height of the vacuum cleaner 100 is not excessively increased.

In a specific embodiment, the range of the dimension a of the first step surface 121 from the bottom surface 111 is 0< a ≦ 4mm, preferably 2mm, which is advantageous for the miniaturization of the vacuum cleaner 100.

As a specific embodiment, as shown in fig. 4 and 5, the intake portion 12 further includes a second step surface 123 and an intake port 124. The second step surface 123 is recessed upward along the first step surface 121, and the suction port 124 is provided on the second step surface 123. The second step surface 123 is recessed upward along the first step surface 121, so that the vacuum cleaner 100 is in a state of being laid on an object to be cleaned, such as a sheet, and at this time, the second step surface 123 is higher than the first step surface 121. When the lower housing 1 is placed upward, the second step surface 123 is recessed with respect to the first step surface 121. The second step surface 123 is located rearward of the first step surface 121 in the front-rear direction of the cleaner 100.

The air enters the first step surface 121 of the air inlet portion 12, bypasses the boss portion 122, enters the second step surface 123, and further enters the suction port 124 to the inside of the cleaner 100.

In a specific embodiment, the height difference c between the second step surface 123 and the first step surface 121 is 0< c ≦ 10mm, and preferably 6mm, thereby facilitating the miniaturization of the vacuum cleaner 100.

As shown in fig. 4 and 5, as a specific embodiment, the lower case 1 further includes a third protrusion 14, the third protrusion 14 is disposed on the bottom surface 111 and is close to the second step surface 123, and the third protrusion 14 protrudes downward along the bottom surface 111. The third projection 14 projects downward along the bottom surface 111, so that the vacuum cleaner 100 is in a state of being laid on an object to be cleaned, such as a sheet, and the third projection 14 projects downward.

In this embodiment, the third bump 14 may be integrally formed with the bottom surface 111 of the body portion 11.

When the airflow enters the second step surface 123, since the third protrusions 14 protrude from the bottom surface 111, the third protrusions 14 contact the object to be cleaned before the bottom surface 111 and press the object to be cleaned, and the object to be cleaned is prevented from being sucked into the second step surface 123, which may cause the second step surface 123 and the suction port 124 to be blocked.

In a specific embodiment, the range of the dimension d of the third bump 14 protruding from the bottom surface 111 is 0< d ≦ 2mm, and preferably 1 mm.

As a specific embodiment, as shown in fig. 4 and 5, the lower case 1 further includes a wind guiding rib 13, and the wind guiding rib 13 penetrates the air intake portion 12 along the air intake direction of the air intake portion 12. The arrangement of the air guiding ribs 13 can be beneficial to guiding the direction of the air flow, so that the air can flow into the air inlet part 12 more smoothly.

In a specific embodiment, the air guiding rib 13 protrudes from the first step surface 121, and does not protrude from the bottom surface 111. When the cleaner moves forward or backward on the object to be cleaned, the protrusion 122 and the air guiding rib 13 can jack up the object to be cleaned, and the air flow bypasses the protrusion 122 and the air guiding rib 13 and enters the air inlet 124, so that the object to be cleaned is not adsorbed on the first step surface 121. The provision of the air guide rib 13 also reduces the resistance of the object to be cleaned due to suction, and thus the cleaner 100 can slide more smoothly.

The air guide rib 13 also penetrates the air inlet portion 12 to jack the second stepped surface 123 against the object to be cleaned, thereby preventing the second stepped surface 123 and the air inlet 124 from being blocked.

In this embodiment, the air guiding rib 13 may be integrally formed with the first step surface 121 and the second step surface 123.

In a specific implementation, the front opening of the air intake portion 12 is larger than the rear opening of the air intake portion 12 in the air intake direction of the air intake portion 12. That is, the air intake passage of the cleaner 100 is gradually contracted from front to rear, thereby generating a sufficient negative pressure.

In summary, the lower housing 1 of the vacuum cleaner 100 and the vacuum cleaner 100 provided in the embodiments of the present application are provided with the protrusion 122, and the protrusion 122 protrudes downward along the first step surface 121. In operation, the protruding portion 122 contacts the object to be cleaned before the first step surface 121, and when the object to be cleaned is adsorbed to the first step surface 121, the protruding portion 122 can jack up the object to be cleaned, so that the airflow flows to the inside of the vacuum cleaner 100 around the protruding portion 122, and the air inlet blockage caused by the attachment of the object to be cleaned and the first step surface 121 is prevented, thereby improving the dust collection quality and improving the user experience.
