Detailed Description
The technical solution of the present invention is further described below by way of specific embodiments. It should be understood by those skilled in the art that the examples are only for the understanding of the present invention and should not be construed as the specific limitations of the present invention.
As shown in fig. 1-4: a foldable injection device comprises a connecting rod 3 and a foldable spray head, wherein a liquid inlet pipe 2 is inserted into the front end position of the connecting rod 3; the insertion depth of the liquid inlet pipe 2 is two thirds of the diameter of the connecting rod 3, the other end of the liquid inlet pipe 2 is connected with the disinfectant tank 1, and compressed air is accessed from an air inlet of the connecting rod 3; the insertion surface of the liquid inlet pipe 2 is an inclined surface, and the inclined surface is high in the inflow direction of compressed air and low in the outflow direction of the compressed air. According to the aerodynamic principle, the pipe diameter of the high-speed fluid at the position of the liquid inlet pipe is reduced, the flow speed is increased, negative pressure is generated at the rear end of the inclined surface, the liquid (disinfectant) in the disinfectant tank 1 is pressed into the liquid inlet pipe 2 under the action of atmospheric pressure, and the liquid and the compressed air are mixed and output to form a gas-liquid flow which can be sufficiently mixed to form foam. The dosage of the disinfectant can be controlled by adjusting the thickness of the liquid inlet pipe 2.
The air outlet of the connecting rod 3 is connected with a second atomizing nozzle 13 through a reducing adapter thread, the side wall of the front end of the connecting rod 3 penetrates through the supporting rod 7, the supporting rod 7 is communicated with the hose 5, and the port of the hose 5 is connected with a first atomizing nozzle 12; the switch valve is arranged on the supporting rod 7, and the opening and closing of the supporting rod 7 can be controlled according to requirements. The folding nozzle shell comprises an edge body 17 and a middle body 16 at two ends, wherein the edge body 17 is connected with the middle body 16 through a rotating shaft 14, and the edge body 17 can rotate by taking the rotating shaft 14 as a center. Folding shower nozzle still includes folding assembly, folding assembly is by sleeve pipe 6, compression spring 8, sleeve spring 9, retrieve spring 10, contact 11 and dop 15 and constitutes, sleeve pipe 6 cup joints in edge body 17 and intermediate body 16 junction, and edge body 17 is connected to sleeve spring 9 one end, and 6 edges of one end connecting sleeve, 6 lower parts of sleeve pipe are equipped with the opening, and contact 11 passes intermediate body 16 and compression spring 8 one end is fixed, and intermediate body 16 inner wall is connected to the compression spring 8 other end, and contact 11 top side is passed through horizontal pole and dop 15 and is connected, and dop 15 inlays in sleeve pipe lower part opening, retrieves spring 10 one end and is fixed in edge body 17, and one end is fixed in contact 11 lower part side.
In the disinfection operation, if a multi-plane object such as a escalator handrail, a doorframe and the like is encountered, only a lower contact point 11 is touched during the use process, the compression spring 8 is compressed, the clamping head 15 is contracted to the middle body 16, the opening of the sleeve 6 is released, the sleeve 6 is pulled away from the position of the rotating shaft 14 under the tension of the sleeve spring 9, at the moment, under the tension of the recovery spring 10 and the self gravity of the edge body 17, the edge body 17 is drooped to change the spraying angle of the device, and the spraying can be carried out on different planes. If necessary, the contacts 11 at both ends are selectively touched, so that one or both edge bodies 17 can be made to droop.
When the horizontal angle needs to be restored, the edge body 17 is held up by hand, the sleeve 6 is pulled towards the middle body 16, so that the lower end opening of the sleeve 6 is embedded into the chuck 15, and the restoration is completed.
As shown in fig. 5, the inner side wall of the rear end of the connecting rod 3 is fixed with a lifting block 4, and the length of the upper surface of the lifting block 4 is larger than that of the lower surface. According to the aerodynamic principle, when high-speed fluid flows through the lifting block, the flow velocity is changed due to the inconsistent strokes of the fluid on the upper surface and the lower surface of the lifting block 4, and upward lifting force is generated. The lifting block 4 is fixedly connected with the connecting rod 3, so that the gravity of the whole injection device can be offset, the arm load of a user can be reduced, and the continuous operation time can be prolonged.
In the embodiment, the first atomizing nozzle 12 and the second atomizing nozzle 13 can be universal atomizing nozzles in the market, the range of the mist outlet angle of a common atomizing nozzle is 45-120 degrees, and the specific type can be selected and installed according to the requirement of disinfection operation.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and the technical solutions and the inventive concepts according to the present invention should be equivalent or changed within the technical scope of the present invention.
