However, the claimed application may be practiced without these specific details and with various changes and modifications based on the following embodiments.
A first embodiment of the present application relates to an air suction device, as shown in fig. 1 to 2, comprising: the silencer comprises a shell 1 and a silencing barrel 2 arranged on the shell 1 and fixedly connected with the shell 1, wherein the silencing barrel 2 is also communicated with the shell 1, the shell 1 is provided with an air inlet side, the shell 1 is used for accommodating at least part of an air suction assembly 3, the air suction assembly 3 can generate air flow entering the shell 1 from the air inlet side of the shell 1 when being opened, and the air suction assembly 3 is also provided with a function of discharging the air flow entering the shell 1 into the silencing barrel 2;

Specifically, as shown in fig. 1 to 2, the housing 1 is a cylindrical housing 1, an air inlet 1-1 is provided below the housing 1, the air inlet 1-1 is an air inlet side, and the silencing barrel 2 includes: the hollow cylinder 2-2 and the wind shielding member 2-3, the hollow cylinder 2-2 is a cylinder, the cylinder and the shell 1 are integrally formed, the cylinder is also communicated with the shell 1 and is located above the shell 1, the wind outlet holes 2-1 are distributed on the hollow cylinder 2-2 in a plurality of circles of surrounding paths, specifically, as shown in fig. 1, in the embodiment, five circles of wind outlet holes 2-1 are formed on the side wall of the hollow cylinder 2-2, and of course, in actual situations, the number of circles of the wind outlet holes 2-1 on the side wall of the hollow cylinder 2-2 can be correspondingly increased or correspondingly reduced. In addition, as shown in fig. 1 to 2, a wind shielding member 2-3 is provided on the hollow cylinder 2-2, and is located at an end of the hollow cylinder 2-2 away from the air intake side of the housing 1.
In addition, it should be emphasized that in practical situations, the hollow cylinder 2-2 and the housing 1 may be connected by a detachable connection, for example, a circle of bolts may be used to connect the hollow cylinder 2-2 and the housing 1.
In addition, specifically, as shown in fig. 2, the suction assembly 3 includes: the motor 3-1 arranged in the shell 1 and close to the air inlet 1-1 and the motor 3-2 for driving the impeller 3-1 to rotate, wherein the center of the impeller 3-1 is aligned with the air inlet 1-1, when the motor 3-2 drives the impeller 3-1 to rotate, the impeller 3-1 throws air out, negative pressure is generated at the center part of the impeller 3-1, air outside the shell 1 is sucked into the impeller 3-1 through the air inlet 1-1 by utilizing the negative pressure, the impeller 3-1 continuously rotates, the sucked air is thrown out continuously, so that air flow is generated, the air flow is pushed by the throwing force of the impeller 3-1 to move upwards along the inner wall of the shell and enter the silencing cylinder 2, part of the air flow is directly discharged from each air outlet hole 2-1, and part of the air flow is greatly impacted onto the wind shielding piece 2-3 because of the throwing force, the air flow is rebounded back after the air flow is impacted onto the wind shielding piece 2-3, when the air flow is impacted onto the wind shielding piece 2-3, the air flow speed is greatly slowed down, the energy of the air flow is continuously rotated, and the air flow is greatly reduced when the air flow is discharged from each air outlet 2-1 is greatly reduced, and noise is greatly generated when the air flow is discharged from each air outlet hole 2-1.
In addition, as shown in fig. 2, the air suction assembly is partially housed in the casing, partially housed in the silencing barrel, specifically, the impeller 3-1 is located in the casing, and a part of the motor 3-2 is located in the silencing barrel.
In addition, in order to enable the air flow of the silencing barrel 2 to be discharged relatively uniformly from the silencing barrel 2, thereby further reducing the noise when the air flow is discharged from the silencing barrel 2, as shown in fig. 1, the number of the air outlet holes 2-1 on each circle of the encircling path is the same, and the aperture is the same, so that the air flow can be discharged uniformly from the silencing barrel 2, when the air flow discharged on the same circle is not uniform enough, the air flow discharged in some places is relatively larger, and when the air flow discharged on one circle is locally larger, the noise at the place is also larger, thereby increasing the noise of the whole air suction device.
In addition, as shown in fig. 1, not only the number of the air outlet holes 2-1 on each round of the encircling path is the same, but also the aperture of each air outlet hole 2-1 on each round of the encircling path is the same, and the apertures of the adjacent two circles of the encircling paths are arranged in a one-to-one correspondence manner, of course, in actual conditions, the aperture of each air outlet hole may not be completely the same, and the number of the air outlet holes 2-1 on each circle of the encircling path may not be completely the same, because if a part is locally arranged on the hollow cylinder 2-2, the part provided with the part will not be provided with the air outlet holes, in addition, the aperture of each air outlet hole 2-1 on any circle of the encircling path is larger than the aperture of each air outlet hole 2-1 on the previous circle of the encircling path in the direction, that is, as shown in fig. 1, the aperture is firstly small, then gradually increased, so that the aperture is not large, and the air outlet hole 2-1 is not large, and the aperture is gradually increased, and thus the exhaust noise can be reduced, and the exhaust noise can be reduced gradually, and the exhaust noise can be greatly reduced gradually, and the aperture is greatly, and the exhaust noise can be greatly reduced.
In addition, as another alternative technical solution, in the actual situation, along the flow direction of the air flow, the aperture of the air outlet hole 2-1 on each surrounding path is gradually increased until the aperture of the air outlet hole 2-1 on each surrounding path is unchanged after the preset value, that is, the air outlet hole 2-1 on each surrounding path is larger than the air outlet hole 2-1 on the previous surrounding path, until the aperture of the air outlet hole 2-1 on a certain surrounding path reaches a certain preset value, the aperture of the air outlet hole 2-1 on each surrounding path behind the surrounding path is not increased any more, so that the aperture of the air outlet hole 2-1 on the hollow cylinder is prevented from being excessively large, and because the air flow can rapidly pass through the excessively large air outlet hole 2-1 and is discharged out of the silencing cylinder, great noise can be generated, so that in order to avoid the excessively large noise, when the aperture is increased to a certain extent, the aperture cannot be increased any more.
In addition, the wind shielding member 2-3 is specifically a control circuit board for controlling the air suction assembly 3, the control circuit board is electrically connected with the motor through a circuit, and the control circuit board can be fixedly connected with the upper end face of the hollow cylinder 2-2 through a circle of screws.

In addition, as shown in FIG. 3, the air suction device 5 has an air inlet side 5-1 and an air outlet side 5-2 opposite to the air inlet side 5-1;
wherein, at least part of one side of the dust collector shell 4 relative to the air outlet side 5-2 of the air suction device 5 is separated from the air outlet side 5-2 of the air suction device 5 to form a first air channel 7 for air flow to pass through, a second air channel 8 communicated with the first air channel 7 is also formed between the dust collector shell 4 and the air suction device 5, and the second air channel 8 extends towards the air inlet side 5-1 of the air suction device 5;
