Thus, in the contemporary fast-paced society, the sweeper is popular with more and more households.

The main functions of the floor sweeping machine are floor sweeping, dust collection and the like, and the existing floor sweeping machine generally adopts a sweeping, sucking or blowing mode to sweep floor garbage into a garbage storage box of the floor sweeping machine so as to achieve the functions of floor sweeping and dust collection. Specifically, the sweeper mainly comprises a garbage storage box and a fan, wherein an air outlet of the fan faces the ground, so that the fan blows air to the ground, and garbage on the ground is blown into the garbage storage box. Because the air outlet of the fan faces the ground, the distance between the air outlet and the ground is relatively short, i.e. the space between the air outlet and the ground is relatively small. When the fan blows towards the ground, air cannot be immediately discharged from the space between the air outlet and the ground in an outward diffusion mode, so that a large amount of air is gathered inside the fan, and then the fan is subjected to larger windage, so that the working efficiency of the fan is influenced, and the service life of the fan is influenced.

Optionally, the filtering structure 120 may be a filter screen, which may filter impurities with a larger volume, so as to prevent some impurities with a larger volume from entering the housing 110 to collide with the fan blades to some extent. Or, the filtering structure 120 may be a filter core, which not only can block some impurities with larger volume from entering the housing 110, but also can adsorb impurities in the air to be entered into the housing 110, so as to play a role in purifying the air to a certain extent.

Thus, in one possible design, the fuselage may further comprise ventilation ducts 200, the ventilation ducts 200 being in communication with the air supply duct 111 and the second air outlet, respectively, the air supply duct 111 being in communication with the second air outlet through the ventilation ducts 200. The ventilation duct 200 communicates with the air supply passage 111 by communicating with the third opening in particular. When the distance between the air supply channel 111 and the side wall or the top wall of the casing is far, the ventilating duct 200 is respectively communicated with the air supply channel 111 and the second air outlet, so that the connection tightness between the air supply channel 111 and the casing can be improved, namely, the connection tightness between the casing 110 and the casing is improved, and the air flowing in the casing 110 is prevented from being excessively blown to other structures in the casing to a certain extent. Of course, when the distance between the air supply duct 111 and the side wall or the top wall of the cabinet is relatively short, the ventilation duct 200 may be provided, and the connection tightness between the housing 110 and the cabinet may be improved.

In one possible design, the first air outlet is also in communication with the ventilation duct 200. In this kind of setting mode, first air outlet and second air outlet all communicate with air pipe 200, air pipe 200 still communicates with air supply channel 111, so set up, air supply channel 111 communicates with first air outlet through air pipe 200, that is, casing 110 communicates with first air outlet through air pipe 200, can make the relative position between casing 110 and the first air outlet more diversified, that is, the limited less of distance between casing 110 and the first air outlet, can be according to the appropriate adjustment of the mounted position of other structures in the casing to improve space utilization.

By arranging the first limiting part 311 and the second limiting part, the stability of the ventilating duct 200 mounted on the casing is improved. And, the first limiting portion 311 and the second limiting portion may further provide a larger operation space for connection of the ventilation duct 200 and the casing, for example, through holes may be formed in the first limiting portion 311 and the second limiting portion, respectively, for the bolts to pass through, and a threaded end is provided on the bolts to connect with nuts, so that the first limiting portion 311 and the second limiting portion are connected, and thus, stability of the ventilation duct 200 mounted on the casing may be further improved.

In an alternative embodiment, as shown in fig. 5, the casing includes a bottom case 310 and an upper cover (not shown), and the first limiting part 311 is disposed on a bottom surface of the bottom case 310. In the installation process, the ventilation duct 200 is placed on the bottom case 310 such that the first and second limiting parts 311 and 311 are engaged with each other, and then the upper cover is covered on the bottom case 310, and the ventilation duct 200 is located between the upper cover and the bottom case 310.

In this arrangement, the ventilation duct 200 can be limited to the housing by the engagement of the guide block and the guide groove, and the ventilation duct 200 can be guided to a certain extent when the ventilation duct 200 is mounted in the housing. As shown in fig. 5, the casing includes a bottom case 310 and an upper cover (not shown), the first limiting portion 311 is a guide block, the guide block is disposed on the bottom surface of the bottom case 310, and the length direction of the guide block (the extending direction of the longest side of the guide block) is relatively perpendicular to or inclined with respect to the bottom surface of the bottom case 310.

By arranging the flange 240, the contact area between the ventilation pipeline 200 and the casing is increased, and the connection stability between the ventilation pipeline 200 and the casing is improved. The first opening 220 and the second air outlet are disposed opposite to each other, so that the first opening 220 is exposed outside the housing 110, which is favorable for discharging the air flowing in the air supply channel 111 to the outside of the housing, thereby reducing the windage of the air supply mechanism 100. Alternatively, the end of the ventilation duct 200 provided with the first opening 220 may be connected to the inner side wall of the casing, and the flange 240 is specifically in contact with the inner side wall of the casing, in this arrangement, the second air outlet communicates with the first opening 220, and the first opening 220 is located inside the casing.

When the casing includes the bottom shell 310 and the top cover, the first air outlet penetrates through the bottom wall of the bottom shell 310, and the second air outlet may be formed by surrounding the top cover and the bottom shell 310 together. For example, a side wall of the bottom case 310 facing away from a bottom wall of the bottom case 310 is provided with a first notch, a side wall of the upper cover facing away from a top wall of the upper cover is provided with a second notch, and when the upper cover is covered on the bottom case 310, the first notch and the second notch are opposite to each other, so that the first notch and the second notch together form a second air outlet.

In some alternative embodiments, as shown in fig. 2, the axis of the ventilation duct 200 extends along a curve, and the outer side wall of the ventilation duct 200 is provided with a avoidance groove 260, so that the ventilation duct 200 may reasonably avoid other structures in the casing. In other alternative embodiments, the ventilation duct 200 includes a soft rubber tube that communicates with the air supply duct 111 and the second air outlet, respectively. The soft rubber cylinder is of a flexible structure and can be made of rubber or plastic and other materials, so that the soft rubber cylinder has certain deformability. Different kinds of floor sweeping machines have different structures in the machine shell, different placement positions of the structures, and different spaces for installing the ventilating duct 200 in the machine shell. In this arrangement, the soft rubber tube can be installed in installation spaces of different shapes, and the universality of the soft rubber tube is higher, so that the universality of the ventilation pipeline 200 is higher.

Optionally, the inner cavity of the soft rubber cylinder is not only respectively communicated with the air supply channel 111 and the second air outlet, but also communicated with the first air outlet. In some alternative embodiments, the first opening 220 is disposed through a side wall of the soft rubber tube, and the side wall of the soft rubber tube is further disposed through a fourth opening 210 and a second air inlet 270, the first opening 220 is disposed opposite to the second air outlet, the fourth opening 210 is disposed opposite to the first air outlet, the side wall of the housing 110 of the air supply mechanism 100 is disposed through a third air outlet 112, and the third air outlet 112 is disposed opposite to the second air inlet 270, so that the air supply channel 111 is respectively communicated with the first air outlet and the second air outlet through the soft rubber tube, that is, the housing 110 is respectively communicated with the first air outlet and the second air outlet through the soft rubber tube. In this embodiment, as shown in fig. 5 and 6, the second air inlet 270 and the first opening 220 are openings at two ends of the soft rubber tube, and the fourth opening 210 is disposed through the bottom wall of the soft rubber tube. As shown in fig. 2 and 3, an end of the soft rubber tube provided with the second air inlet 270 is connected with an end of the housing 110 provided with the third air outlet 112, so that the second air inlet 270 is communicated with the third air outlet 112. Optionally, one end of the housing 110 provided with the third air outlet 112 is inserted into the second air inlet 270, and the soft rubber cylinder is in interference fit with the housing 110, so that the air supply channel 111 is communicated with the inner cavity of the soft rubber cylinder. The multiple convex strips 230 are arranged on the outer side wall of the soft rubber barrel at intervals, the flange 240 is specifically arranged at one end of the soft rubber barrel, which is provided with the first opening 220, extends out of the shell from the second air outlet, the flange 240 is contacted with the outer side wall of the shell, the guide grooves on the convex strips 230 are respectively matched with the corresponding guide blocks, and the flange 240 is matched with the outer side wall of the shell, so that the soft rubber barrel is stably installed in the shell. After the fan blades inside the casing 110 start to rotate, the air flowing inside the casing 110 enters the inner cavity of the soft rubber cylinder through the second air inlet 270 from the third air outlet 112, and is finally discharged from the first air outlet and the second air outlet respectively.

In one possible design, as shown in fig. 5 and 6, the ventilation duct 200 has a diverging section 250, and the cross-sectional area of the diverging section 250 gradually increases from one end near the air supply passage 111 to one end near the second air outlet. It should be noted that the cross-sectional area of the diverging section 250 is the cross-sectional area of the inner wall of the ventilation duct 200, and the cross-sectional area of the inner wall of the ventilation duct 200 is specifically the cross-sectional area perpendicular to the axis of the ventilation duct 200. The larger the cross-sectional area of the inner wall of the ventilation duct 200, the smaller the flow velocity of the air in the inner cavity corresponding to the inner wall of the section, so in this arrangement, the provision of the diverging section 250 can properly reduce the flow velocity of the air blown toward the second air outlet, and to some extent prevent the air flow blown out from the second air outlet from lifting the impurities on the ground. The cross-sectional area of the second air outlet is also perpendicular to the opening direction of the second air outlet. When the ventilation duct 200 includes a soft rubber tube, the diverging section 250 is specifically disposed at an end of the soft rubber tube where the first opening 220 is disposed, and the cross-sectional area of the diverging section 250 gradually increases from an end near the fourth opening 210 to an end near the first opening 220, so that the cross-sectional area of the first opening 220 is larger, and thus the flow velocity of the air blown out from the first opening 220 is smaller.

In some alternative embodiments, the cross-sectional area of the first air outlet is smaller than the cross-sectional area of the second air outlet. Since the larger the opening area of the air outlet is, the smaller the flow velocity of the air blown out from the air outlet is, whereas the smaller the opening area of the air outlet is, the faster the flow velocity of the air blown out from the air outlet is. Therefore, in the arrangement mode, the air blown out from the first air outlet can be faster in flow speed, impurities on the ground can be blown up more easily, and the cleaning effect is better.

In some alternative embodiments, as shown in fig. 1 to 3, the bottom surface of the main body is further provided with a dust collection opening 320 and an air guide channel 340, the air guide channel 340 is communicated with the first air outlet, the extending direction of the air guide channel 340 is inclined relative to the horizontal plane, and one end of the air guide channel 340 near the first air outlet is closer to the dust collection opening 320 relative to one end far from the first air outlet. So set up, can make the air that blows out by first air outlet blow off to the direction that is close to dust absorption mouth 320 behind the wind-guiding passageway 340, after the air that blows out from wind-guiding passageway 340 blows up subaerial impurity, get into dust absorption mouth 320 more easily in, clean effect is better. Optionally, the body includes a dustbin, the dustbin is located on the bottom shell 310, the dust collection opening 320 penetrates through the bottom wall of the bottom shell 310, and the dust collection opening 320 is communicated with the inner cavity of the dustbin. Impurities entering the dust collection opening 320 can be stored in the dustbin first and finally cleaned and recycled uniformly.

In some alternative embodiments, as shown in fig. 3, a rolling brush 330 is further disposed between the dust collection port 320 and the air guide passage 340. After the air blown out from the air guide channel 340 blows up the impurities on the ground, the impurities can enter the dust collection opening 320 under the driving of the rolling brush 330, so that the cleaning effect of the sweeper provided by the embodiment of the utility model is further improved.

The above description is illustrative of the various embodiments of the utility model and is not intended to be limiting, but is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
