Description

  The present invention relates to a cleaning nozzle and a cleaning device for removing dirt adhering to a cleaning surface such as a floor surface or a road surface.

  As a technique for cleaning a road surface on which a vehicle travels, a technique for sucking an object attached to the road surface while injecting an air flow onto the road surface is known (Patent Document 1).

JP 2005-48421 A

  Since the technique described in Patent Document 1 includes an injection unit that injects air and a suction unit that sucks adhering substances, the area occupied by the injection unit and the suction unit increases. Since the technique described in Patent Document 1 is intended for a wide cleaning object such as a road surface, there is no particular problem even with a large apparatus. However, when the indoor cleaning is to be performed, downsizing of the entire apparatus is required.

  In the technique described in Patent Document 1, cleaning objects such as dust are scattered by the injection of air injected from the injection unit. Although the jet of water can prevent the scattering of the cleaning object, when using the water flow, it is necessary to treat the sewage mixed with dust, so there is a desire to use the jet of air. is there.

  An object of the present invention is to reduce the size of the entire apparatus and prevent scattering of an object to be cleaned in a structure that sucks dirt while injecting an air flow.

  A cleaning nozzle according to the present invention includes a jet part including a jet port that jets high-pressure air toward a cleaning surface, and a suction port that accommodates the jet part and opens to the cleaning surface and sucks dust on the cleaning surface A suction part.

  According to the above configuration, in the configuration of the type that sucks dirt while ejecting the air flow, the suction portion for sucking air is configured to accommodate the ejection portion for ejecting the high-pressure air flow. The cleaning nozzle can be made smaller as compared with the configuration in which the part and the ejection part are arranged in parallel, and the overall size of the apparatus can be reduced. Moreover, since the ejection part is accommodated in the suction part, the cleaning object does not scatter around and is directly sucked into the suction part, so that the cleaning object does not scatter.

  In the present invention, an elastic member surrounding the suction port may be provided. According to this configuration, air can be blocked between the inside and the outside of the cleaning nozzle, and suction of air outside the cleaning nozzle can be prevented, so that a reduction in the suction force of the cleaning nozzle can be prevented. .

  Moreover, in this invention, you may make it provide the support part which supports the said ejection part and the said suction part movably with respect to a cleaning surface. According to this configuration, the cleaning nozzle can be easily moved.

  Moreover, in this invention, you may make it provide the connection part which connects the said suction part to the vertical or horizontal direction. According to this configuration, the cleaning area of the cleaning nozzle can be increased according to the size of the cleaning surface.

  As described above, according to the present invention, in the configuration of a type that sucks dirt while jetting an air flow, the jet portion for jetting a high-pressure air flow is accommodated in the suction portion that sucks air. Therefore, the cleaning nozzle can be made smaller than the configuration in which the suction part and the ejection part are arranged in parallel, and the entire apparatus can be reduced in size. Moreover, since the ejection part is accommodated in the suction part, the cleaning object does not scatter around and is directly sucked into the suction part, so that the cleaning object does not scatter.

The figure which shows the structure of the cleaning nozzle which concerns on one embodiment of this invention. FIG. 2 is a view showing a bottom surface of the cleaning nozzle shown in FIG.

  FIG. 1 is a diagram showing a configuration of a cleaning nozzle according to an embodiment of the present invention, and FIG. 2 is a diagram showing a bottom surface of the cleaning nozzle. The cleaning nozzle 100 includes an ejection unit 110 that ejects a high-pressure air flow toward the cleaning surface, and a suction unit 120 that houses the ejection unit 110 and that opens to the cleaning surface and sucks dust on the cleaning surface. Prepare. The ejection unit 110 includes an ejection pipe 111 to which high-pressure air generated by a cleaning device main body (not shown) is supplied, and an ejection port 113 for ejecting the supplied high-pressure air to the cleaning surface.

  Further, the suction part 120 accommodates the ejection part 110 therein, is provided with a suction port that opens toward the cleaning surface and has a trapezoidal cross section, and sucks air containing dust sucked from the suction port. Is provided. Air sucked from the suction port is supplied to a cleaning device main body (not shown) through a suction pipe.

  The cleaning device main body on which the cleaning nozzle is mounted has a function of generating high-pressure air supplied to the ejection unit 110 and a suction function of generating suction force supplied to the suction unit 120.

  Further, a hard rubber 123 is provided as an elastic member at the suction port of the suction unit 120 that opens toward the cleaning surface. This is because when the suction part 120 sucks outside air, the suction force inside the cleaning nozzle is reduced, so that the inside and the outside of the cleaning nozzle 100 are blocked. By bringing the elastic member provided in the suction part 120 into contact with the cleaning surface, air can be blocked between the inside and the outside of the cleaning nozzle 100. However, since it is necessary to move the cleaning nozzle while the elastic member is in contact with the cleaning surface during cleaning, the elastic member that contacts the cleaning surface may be made of hard rubber so that the cleaning nozzle can be easily moved. preferable.

  Further, in order to facilitate the movement of the cleaning nozzle, a caster roller 125 may be provided around the suction part 120 to support the cleaning nozzle 100 so as to be movable with respect to the cleaning surface.

  In addition, you may make it connect the cleaning nozzle 100 according to the magnitude | size of a cleaning surface. In the illustrated example, the cleaning area is enlarged by connecting the cleaning nozzle 120 in the longitudinal direction via a connecting member (not shown). In addition to connecting the cleaning nozzle 120 in the vertical direction as in the illustrated example, it may be connected in the horizontal direction.

  According to the above configuration, in the configuration of a type that sucks dirt while jetting an air flow, the suction portion that sucks air is configured to accommodate the jetting portion for jetting the high-pressure airflow. The cleaning nozzle can be made smaller as compared with the configuration in which the part and the ejection part are arranged in parallel, and the overall size of the apparatus can be reduced. Moreover, since the ejection part is accommodated in the suction part, the cleaning object does not scatter around and is directly sucked into the suction part, so that the cleaning object does not scatter.
