The embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 9, an embodiment of the present application discloses a sweeping device 100 for sweeping an area such as a road surface to keep the road surface clean. The cleaning device 100 can be applied to a sanitation vehicle, a cleaning vehicle, a sweeping vehicle, a washing and sweeping vehicle, a garbage truck, a sweeping vehicle, etc., and of course, any device having a cleaning function may be used, and the application of the cleaning device 100 in the embodiment of the present application is not limited.

The disclosed cleaning apparatus 100 includes an apparatus body 110, the apparatus body 110 being a main cleaning member of the cleaning apparatus 100, the apparatus body 110 may be provided with a high pressure jet head through which a high pressure water jet may be injected toward a road surface to wash the road surface by the high pressure water jet, thereby peeling contaminants from the road surface. Meanwhile, in order to prevent the road surface water accumulation from influencing the passing, the device main body 110 may further include an absorption part 111, for example, an absorption end, and under the absorption action of the absorption part 111, the washed water accumulation may be absorbed and collected, so as to ensure that the washed road surface is not likely to have a large amount of water accumulation.

It should be noted here that, regarding the specific structure of the device main body 110 and the operation principle thereof, other related technologies may be referred to as long as the functions of water spray flushing, negative pressure adsorption and the like can be realized.

Referring to fig. 1 to 5, in order to ensure that the cleaning apparatus 100 has a good cleaning effect, the cleaning apparatus 100 further includes a first cleaning member 120 and a second cleaning member 130, wherein the first cleaning member 120 and the second cleaning member 130 are respectively disposed at both sides of the apparatus body 110 in the first direction. Here, the first direction is a leftward or rightward direction of the cleaning apparatus 100 in a use state, and may be also understood as a leftward or rightward direction of the sanitation vehicle.

In some embodiments, the first purge member 120 may be disposed at the left end of the apparatus body 110, and the second purge member 130 may be disposed at the right end of the apparatus body 110, such that the first and second purge members 120 and 130 are spaced apart from each other in the left-right direction of the sweeping device 100, so as to purge the accumulated water from the left and right sides, respectively.

To perform the purge, the first purge member 120 and the second purge member 130 each have an air blowing port to respectively blow out a high pressure air flow to the road surface through the respective air blowing ports, so that the accumulated water is purged by the high pressure air flow to gather the accumulated water. Specifically, the first blowing member 120 may have a first blowing port 1211, and the second blowing member 130 may have a second blowing port 1311, and the first blowing port 1211 is located at the left end of the apparatus body 110 and near the road surface, and the second blowing port 1311 is located at the right end of the apparatus body 110 and near the road surface, during the sweeping operation of the sweeping apparatus 100, so as to blow off the accumulated water on the road surface from the left and right sides.

In order to gather the accumulated water to improve the suction effect on the accumulated water, in the embodiment of the present application, the axis of the air blowing port of the first purge member 120 is inclined toward the second purge member 130 with respect to the second direction, and the axis of the air blowing port of the second purge member 130 is inclined toward the first purge member 120 with respect to the second direction. Here, the second direction is an upward or downward direction of the sweeping device 100 in a use condition, and may also be understood as an upward or downward direction of the sanitation vehicle. Therefore, the second direction is perpendicular to the first direction.

Based on the above arrangement, the air flow blown out through the air blowing port (i.e., the first air blowing port 1211) of the first sweeping member 120 is inclined toward the second sweeping member 130, and the air flow blown out through the air blowing port (i.e., the second air blowing port 1311) of the second sweeping member 130 is inclined toward the first sweeping member 120, that is, the air flow blown out through the first air blowing port 1211 is inclined toward the second sweeping member 130 when flowing toward the road surface so as to sweep the accumulated water on the road surface toward the second sweeping member 130, and similarly, the air flow blown out through the second air blowing port 1311 is inclined toward the first sweeping member 120 when flowing toward the road surface so as to sweep the accumulated water on the road surface toward the first sweeping member 120, so that the accumulated water is gathered by the air flows on the left and right sides so as to be sucked.

In the embodiment of the application, the cleaning device 100 can have the functions of jetting high-pressure water jet and negative pressure suction, so that pollutants on the road surface can be stripped through the high-pressure water jet, and accumulated water on the road surface is sucked away through the negative pressure suction, so that the road surface is clean and free of accumulated water; the sprayed high-pressure water jet flow can be gathered by the first purging component 120 and the second purging component 130 to improve the negative pressure suction effect; moreover, the high-pressure air flow purging device can enable accumulated water on the road surface to be in a suspension state, and is beneficial to the absorption of the accumulated water, so that the pumping efficiency can be improved.

Compare in the mode of rubber lining board gathering together ponding, the mode that adopts the mode of blowing to gather together ponding need not first blowing to sweep component 120 and second and sweep component 130 and road surface contact, thereby can avoid receiving the road surface wearing and tearing and influence and gather together ponding and influence the problem of negative pressure suction, and even cleaning device 100 turns to or makes the movement track take place to deflect along curve operation, can not lead to cleaning device 100's the outside to break away from the road surface and influence and gather together ponding or influence the negative pressure suction yet, and then guaranteed cleaning device 100's the effect of cleaning.

In order to achieve the function of dredging the air flow, the first blowing member 120 and the second blowing member 130 may each include a blowing cavity, i.e., a first blowing cavity 121 and a second blowing cavity 131, so as to dredge the air flow on the left and right sides through the first blowing cavity 121 and the second blowing cavity 131, respectively.

In some embodiments, the first air blowing opening 1211 is disposed in a region of the first air blowing cavity 121 near the bottom, and the first air blowing opening 1211 is communicated with an inner cavity of the first air blowing cavity 121; meanwhile, a first air inlet 1212 is disposed in an area of the first air blowing cavity 121 near the top, and the first air inlet 1212 is communicated with an inner cavity of the first air blowing cavity 121.

Based on the above arrangement, the high-pressure gas may enter the inner cavity of the first blowing cavity 121 through the first air inlet 1212, and is channeled through the inner cavity of the first blowing cavity 121, so that the high-pressure gas flows to the first blowing port 1211, and finally the high-pressure gas is blown out through the first blowing port 1211 in the form of an air flow and is blown away toward the road surface, the blowing direction of the air flow is not perpendicular to the road surface, but is inclined by a certain angle toward the second blowing member 130, that is, the blowing direction of the air flow forms a certain included angle with the normal direction of the road surface, so that the accumulated water on the road surface can be blown away toward the second blowing member 130, and the accumulated water on the road surface is gathered toward the second blowing member 130.

Similarly, the second blowing port 1311 is disposed in a region of the second blowing cavity 131 near the bottom, and the second blowing port 1311 is communicated with the inner cavity of the second blowing cavity 131; meanwhile, a second air inlet 1312 is formed in a region of the second air blowing cavity 131 near the top, and the second air inlet 1312 is communicated with an inner cavity of the second air blowing cavity 131.

Based on the above arrangement, the high-pressure gas can enter the inner cavity of the second blowing cavity 131 through the second air inlet 1312, and is guided through the inner cavity of the second blowing cavity 131, so that the high-pressure gas flows to the second blowing port 1311, and finally the high-pressure gas is blown out through the second blowing port 1311 in the form of an air flow and is blown towards the road surface, the blowing direction of the air flow is not perpendicular to the road surface, but inclines at a certain angle towards the first blowing member 120, that is, the blowing direction of the air flow forms a certain included angle with the normal direction of the road surface, so that the accumulated water on the road surface can be blown towards the first blowing member 120, and the accumulated water on the road surface is gathered towards the first blowing member 120.

In order to blow the air flow obliquely, the first blowing member 120 and the second blowing member 130 are structurally designed to limit the direction of the air flow, so that the air flow can be blown out according to the preset requirement.

Referring to fig. 5, in some embodiments, the blowing cavity of the first blowing member 120 (i.e., the first blowing cavity 121) has a first bottom wall 1213, the first bottom wall 1213 is disposed at an angle to the second direction, and the first bottom wall 1213 extends obliquely toward the second blowing member 130. When the cleaning device 100 is in use, the second direction may be downward, and at this time, the gas entering the first blowing cavity 121 from the first air inlet 1212 flows downward to the first blowing port 1211, and during the flowing process, the gas is subjected to the dredging action of the first bottom wall 1213, so that the gas flows obliquely inward from top to bottom (i.e., toward the second blowing member 130), and thus the gas flow blown out through the first blowing port 1211 can flow obliquely, so as to achieve the gathering effect on the road surface water.

Optionally, an included angle between the first bottom wall 1213 and a normal line of the road surface may range from 5 ° to 75 °, and includes 5 °, 10 °, 15 °, 20 °, 30 °, 45 °, 60 °, 70 °, 75 °, and the like, and of course, other degrees are also possible.

Likewise, the blowing cavity (i.e., the second blowing cavity 131) of the second blowing member 130 has a second bottom wall 1313, the second bottom wall 1313 is disposed at an angle to the second direction, and the second bottom wall 1313 extends obliquely toward the first blowing member 120. When the sweeping device 100 is in use, the second direction may be downward, and at this time, the air entering the second blowing cavity 131 from the second air inlet 1312 flows downward to the second air blowing port 1311, and during the flowing process, the air is subjected to the dredging action of the second bottom wall 1313, so that the air flows obliquely inward from top to bottom (i.e., in the direction of the first sweeping member 120), and thus the air flow blown out through the second air blowing port 1311 may flow obliquely, so as to achieve the gathering effect on the road surface water.

Optionally, the included angle between the second bottom wall 1313 and the normal line of the road surface may range from 5 ° to 75 °, and includes 5 °, 10 °, 15 °, 20 °, 30 °, 45 °, 60 °, 70 °, 75 °, and the like, and of course, may also range from other degrees.

In some embodiments, the inner surfaces of first bottom wall 1213 and second bottom wall 1313 may be planar or curved, and may be selected according to practical situations.

With continued reference to FIG. 5, to form the first purge orifice 1211, the purge cavity of the first purge member 120 (i.e., the first purge cavity 121) also has a first sidewall 1214 proximate the second purge member 130, i.e., the first sidewall 1214 is disposed opposite the second purge member 130. An angle formed between the first side wall 1214 and the first bottom wall 1213 is an acute angle, and the air blowing port (i.e., the first air blowing port 1211) of the first blow-sweeping member 120 is formed between the first bottom wall 1213 and the first side wall 1214. When the cleaning device 100 is in use, the first sidewall 1214 may be perpendicular to the road surface, and the included angle between the first sidewall 1214 and the first bottom wall 1213 is the included angle between the first bottom wall 1213 and the normal of the road surface, and the included angle is in the range of 5 degrees to 75 degrees.

Based on the above arrangement, the gas in the first blowing cavity 121 can be guided by the first side wall 1214 and the first bottom wall 1213 together, so as to ensure that the gas can flow smoothly to the first blowing opening 1211 and can be blown out at the preset included angle.

Further, in the first direction, the bottom end of the first side wall 1214 and the bottom end of the first bottom wall 1213 are spaced apart, and in the second direction, the bottom end of the first bottom wall 1213 protrudes from the bottom end of the first side wall 1214, that is, the bottom end of the first side wall 1214 is recessed from the bottom end of the first bottom wall 1213, so that a notch is formed between the bottom end of the first side wall 1214 and the bottom end of the first bottom wall 1213, and the notch is the first blowing opening 1211.

Moreover, since the first bottom wall 1213 is disposed obliquely, the gas flowing along the first bottom wall 1213 is not affected by the first side wall 1214, so that the air flow blown out by the first air blowing opening 1211 can flow along the dredging direction of the first bottom wall 1213, thereby gathering accumulated water.

It is considered that both the first bottom wall 1213 and the first side wall 1214 have a certain length in the third direction, and in the first direction, the bottom end of the first bottom wall 1213 is disposed spaced apart from the bottom end of the first side wall 1214. In this way, the first air blowing opening 1211 is an elongated opening along the third direction, and the first air blowing opening 1211 can increase the air blowing distance in the third direction of the cleaning device 100, so as to increase the area of the air blowing area and improve the air blowing effect. Here, the third direction is a forward or backward direction of the sweeping device 100 in a use condition, and may also be understood as a forward or backward direction of the sanitation vehicle. It can be seen that the third direction is perpendicular to the first direction and the second direction, respectively.

Likewise, to form the second blowing port 1311, the blowing cavity (i.e., the second blowing cavity 131) of the second blowing member 130 also has a second side wall 1314 facing the first blowing member 120, i.e., the second side wall 1314 is disposed opposite the first blowing member 120. The angle formed between the second side wall 1314 and the second bottom wall 1313 is acute, and the air blowing port of the second purge member 130 (i.e., the second air blowing port 1311) is formed between the second bottom wall 1313 and the second side wall 1314. When the cleaning device 100 is in use, the second sidewall 1314 may be perpendicular to the road surface, and the angle between the second sidewall 1314 and the second bottom wall 1313 is the angle between the second bottom wall 1313 and the normal of the road surface, and is in the range of 5 ° to 75 °.

With the above arrangement, the gas in the second blowing cavity 131 can be ducted by the second side wall 1314 and the second bottom wall 1313 together, so as to ensure that the gas can flow smoothly to the second blowing port 1311 and can be blown out at a preset angle.

Further, in the first direction, the bottom end of the second side wall 1314 is spaced from the bottom end of the second bottom wall 1313, and in the second direction, the bottom end of the second bottom wall 1313 protrudes out of the bottom end of the second side wall 1314, that is, the bottom end of the second side wall 1314 is recessed by a portion compared with the bottom end of the second bottom wall 1313, so as to form a gap, which is the second air blowing port 1311.

Moreover, the second bottom wall 1313 is disposed obliquely, so that the gas flowing along the second bottom wall 1313 is not affected by the second side wall 1314, and therefore it can be ensured that the airflow blown out by the second air blowing port 1311 can flow along the dredging direction of the second bottom wall 1313, and a gathering effect is achieved on accumulated water.

Considering that both the second bottom wall 1313 and the second side wall 1314 have a certain length in the third direction, and in the first direction, the bottom end of the second bottom wall 1313 is spaced from the bottom end of the second side wall 1314, so that the second air blowing port 1311 is an elongated opening arranged along the third direction, thereby increasing the blowing size of the cleaning device 100 in the third direction, and further increasing the area of the blowing region to improve the blowing effect.

In order to enable the gas entering the blowing cavity (i.e., the first blowing cavity 121 or the second blowing cavity 131) to flow more uniformly to the blowing port (i.e., the first blowing port 1211 or the second blowing port 1311), the embodiment of the present application designs the shape of the blowing cavity.

Referring to fig. 6, in some embodiments, a thickness dimension of the blowing cavity in the first direction decreases from a region close to the air inlet to a region far from the air inlet, so that the thickness of the blowing cavity close to the air inlet is greater than that far from the air inlet.

In a more specific embodiment, the air inlet may be disposed near the rear end of the blowing cavity, and the blowing cavity becomes thinner from the rear to the front.

Based on the arrangement, the volume of the inner cavity of the blowing cavity close to the front end is relatively small, and the volume of the inner cavity close to the rear end is relatively large.

The reason for adopting the above design is: after gas gets into the cavity of blowing, the inner chamber along the cavity of blowing is by the diffusion that flows forward backward, still to the diffusion that flows of blowing mouthful department, if design for equal thickness around the cavity of blowing, this moment under the same circumstances of other parameters (e.g., height, width etc.), the cavity of blowing is the same basically in the ascending volume in front and back direction, because all directions diffusion velocity is the same basically, be unfavorable for gas to flow to the front end of the cavity of blowing, thereby it is little to cause the gas flow that the mouth of blowing blew in the region that is close to the front end, and the gas flow that the region that is close to the rear end blew out is big, and then make and sweep inhomogeneously, leave over ponding easily and influence the effect of sweeping.

Adopt the cavity of blowing of this application embodiment, because the region that is close to the front end is relatively thin, and the volume is less relatively, under the circumstances of letting in equal volume gas, the volume is less, and the sectional area is less, and the velocity of flow is faster, thereby, be favorable to gas by backward forward flow, thereby can guarantee that the gas flow of blowing mouth each department differs by little, in order to guarantee to sweep the effect.

Except for the change of the thickness of the blowing cavity, the height of the blowing cavity can be changed to ensure the blowing effect. Referring to fig. 7, in some embodiments, the height dimension of the blowing cavity in the second direction decreases from the area close to the air inlet to the area far from the air inlet, so that the height of the blowing cavity near the air inlet is greater than the height of the blowing cavity far from the air inlet.

In a more specific embodiment, the air inlet may be disposed at a position near the top of the rear end of the blowing cavity, and the height of the blowing cavity is gradually reduced from back to front, or the height of the blowing cavity is unchanged in a region from the front end to the rear end by taking a certain position between the front end and the rear end as a boundary, and the height of the blowing cavity is gradually reduced in a region from the position to the front end.

Based on the arrangement, the volume of the inner cavity of the blowing cavity close to the front end is relatively small, and the volume of the inner cavity close to the rear end is relatively large.

The reason for the design in the manner of changing the height is basically similar to the reason for the design in the manner of changing the thickness described above. Because the area of the blowing cavity close to the front end is relatively low, the volume is relatively small (under the condition that the sizes such as thickness and width are basically unchanged), and under the condition that gas with the same volume is introduced, the smaller the volume is, the smaller the sectional area is, the faster the flow speed is, so that the gas can flow from back to front, the gas flow at each part of the blowing port can be ensured to have little difference, and the blowing effect is ensured.

It should be noted here that the above-mentioned manner of changing the thickness of the blowing cavity and the manner of changing the height of the blowing cavity may be implemented individually or in combination, and the purpose of reducing the volume of the front region of the blowing cavity may be achieved in all the manners. In addition, the present invention may be implemented in other ways, and the embodiments of the present invention are not limited to this.

In addition, in order to protect the components such as the apparatus main body 110, the first purge member 120, and the second purge member 130, the cleaning apparatus 100 may further include a shield cover, and the components such as the apparatus main body 110, the first purge member 120, and the second purge member 130 may be covered by the shield cover to provide a protective effect, and appearance performance of the cleaning apparatus 100 may be improved.

When the first and second purge members 120 and 130 are disposed at the left and rear ends of the device body 110, respectively, the shape of the shield can be adapted in such a manner that the thickness and/or height of the shield is changed, so as to ensure that the shield can completely cover the device body 110, the first and second purge members 120 and 130.

In order to satisfy the thickness change of the blowing cavity and the requirement that the air current blows off along the inclined direction, the bottom wall of the blowing cavity can be designed according to the embodiment of the application.

Referring to fig. 7 and 9, in some embodiments, the width of the first bottom wall 1213 is greater proximate to the air inlet than distal to the air inlet in the third direction. Alternatively, the first bottom wall 1213 may have a plate-like structure like a trapezoid or a triangle. Based on this, both can guarantee that the mouth of blowing is rectangular shape opening to make the air current blow off through the mouth slope of blowing, can satisfy the shape design requirement of blowing the cavity again.

To accommodate different operating conditions, the ground clearance of each of the first and second purge members 120, 130 may be adjusted. Based on this, the sweeping device 100 may further include an adjustment assembly 140, and the first and second purging members 120 and 130 are respectively connected to the device body 110 through the adjustment assembly 140 and are movable in a second direction (i.e., upward or downward in a use condition of the sweeping device 100) with respect to the device body 110. Based on this, the ground clearance of the first purge member 120 and the ground clearance of the second purge member 130 can be respectively adjusted by the adjusting assembly 140, so as to adapt to the working conditions of various road surfaces.

Referring to fig. 6 to 9, in some embodiments, the adjusting assembly 140 may include an adjusting member 141 and a fixing member 142, wherein the fixing member 142 is connected to the first purging member 120 or the second purging member 130, the fixing member 142 is provided with a long hole 1421 extending along the second direction, and the adjusting member 141 is inserted into the long hole 1421 and connected to the device body 110.

Based on the above arrangement, when there is no need to adjust the first purge member 120 or the second purge member 130, the adjuster 141 may be securely coupled with the apparatus body 110 to firmly fix the first purge member 120 or the second purge member 130 to the apparatus body 110; when adjustment is needed, the fastening connection between the adjusting member 141 and the device main body 110 is released, and at this time, the adjusting member 141 releases the pressing action on the fixing member 142, so that the fixing member 142 can be adjusted through the long hole 1421, and the ground clearance of the first purging member 120 or the second purging member 130 can be adjusted to adapt to different working conditions. Alternatively, the adjuster 141 may be a fastening bolt.

It should be noted that, some specific structures of the sanitation vehicle and the working principle thereof may refer to the related art, and are not described herein again.

To achieve the adsorption of the contaminants, the soil pick-up device 300 may include a soil pick-up pipe 310, a container 320, and a blower 330, wherein the soil pick-up pipe 310 is used for transporting the contaminants, the container 320 is used for containing the contaminants, and the blower 330 provides power for the adsorption of the contaminants.

Referring to fig. 10, in some embodiments, one end of the soil suction pipe 310 is connected to the outlet of the apparatus body 110, the other end of the soil suction pipe 310 is connected to the inlet of the container 320, the inlet of the blower 330 is connected to the outlet of the container 320, and the outlet of the blower 330 is connected to the air inlet of the first purging member 120 or the second purging member 130 through the purging duct 150. Alternatively, the apparatus body 110 may include an adsorption part 111, and the adsorption part 111 may be an adsorption head.

Based on the above arrangement, when the blower 330 is started, the gas in the container 320 is pumped out and is respectively conveyed to the first purging component 120 and the second purging component 130 through the blowing pipeline 150, so that in the process of cleaning the road surface, the cleaning water and other pollutants are gathered to the middle through the purging road surface inclined inwards from the left side and the right side by the first purging component 120 and the second purging component 130, and the adsorption effect can be improved; meanwhile, because the gas in the container 320 is continuously pumped out, a certain vacuum degree is formed in the container, and a certain vacuum degree is formed at the adsorption port of the adsorption component 111 through the sewage suction pipe 310, pollutants such as accumulated water on the road surface can be adsorbed, so that pollutants such as accumulated water are adsorbed by the adsorption component 111, and are transmitted to the container 320 through the sewage suction pipe 310 to be collected, so that the road surface is ensured to be clean and free of accumulated water.

Therefore, the gas used in the purging process is derived from the adsorbed gas, so that the gas can be recycled among the adsorption part 111, the sewage suction pipe 310, the container 320, the fan 330, the blowing pipeline 150 and the two purging members, and the separate gas supply device in the purging process can be avoided, so that the use of parts can be reduced, the complexity of the sanitation cleaning vehicle can be reduced, the energy can be saved, and the manufacturing cost and the operating cost of the sanitation cleaning vehicle can be reduced.

To sum up, in the embodiment of the application, high-pressure air flow can be blown out from the left side and the right side to the road surface, so that accumulated water on the road surface becomes a suspended state, and the accumulated water on the edge of the device main body 110 can be gathered, which is beneficial for sucking the accumulated water, thereby improving the sucking efficiency and effect; besides, the ground clearance of each air blowing port can be dynamically adjusted to adapt to different working environments; compared with a rubber lining plate mode, the mode that accumulated water is gathered by high-pressure airflow is adopted to enable the cleaning device 100 to have a higher ground clearance, so that the cleaning device 100 is not easy to wear, and the service life of the cleaning device 100 is guaranteed.
