Description

Technical Field

[0001] The utility model relates to the field of nozzles of window cleaning machines, in particular to a nozzle structure of a window cleaning machine. Background Art

[0002] A window cleaning machine is a machine that automatically wipes window glass. It uses an internal vacuum adsorption mechanism to adsorb on the glass and cooperates with a cleaning roller to wipe the glass surface.

[0003] In the prior art, window cleaning machines usually work by using a single nozzle atomizing water spraying method. This water spraying method has certain disadvantages. Since the single nozzle fails to form a radial spraying effect, the water spraying volume is insufficient and stubborn stains are not cleaned cleanly. At the same time, the water spraying volume is too small, resulting in the windows becoming dirtier the more they are wiped. Usually, the wiping effect does not meet expectations, and the machine can only be run multiple times for repeated wiping, which prolongs the window cleaning time. Summary of the Invention

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a nozzle structure of a window cleaning machine, comprising a window cleaning machine shell, both ends of the window cleaning machine shell are provided with mounting grooves, two nozzle mechanisms are symmetrically installed inside the window cleaning machine shell, a nozzle cover is clamped on the outer side of the nozzle mechanism, the outer wall of the nozzle cover is clamped on the inner wall of the mounting groove, the nozzle mechanism includes a nozzle part clamped on one end of the nozzle cover, three connecting holes are provided on the output port of the nozzle part, and the two connecting holes located on both sides are symmetrically distributed in a fan shape with the middle connecting hole.

[0006] As a further solution of the present invention: the nozzle mechanism further includes three branch pipes integrally formed on the nozzle component, the three branch pipes are aligned one by one with the three connecting holes, and nozzles are installed at the output ends of the branch pipes.

[0007] As a further solution of the present invention: the nozzle mechanism also includes a main pipe installed at the input end of the nozzle component, the outer wall of the main pipe is threadedly connected to a water inlet connector, and the input end of the water inlet connector is integrally formed with a water inlet nozzle.

[0008] As a further solution of the present invention: the inner wall of the connecting cavity of the water inlet joint is provided with a sealing ring in contact with one end of the main pipe.

[0009] As a further solution of the present invention: a connection groove for inserting the end of the nozzle component is provided at the connection position between the nozzle cover and the nozzle component.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 6 In an embodiment of the present invention, a nozzle structure of a window cleaning machine includes a window cleaning machine housing 1, both ends of which are provided with mounting grooves 2, two nozzle mechanisms are symmetrically installed inside the window cleaning machine housing 1, and a nozzle cover 3 is clamped on the outer side of the nozzle mechanism, and the outer wall of the nozzle cover 3 is clamped on the inner wall of the mounting groove 2.

[0022] In this embodiment: when the window cleaning machine is wiping the glass, by starting the water pump installed inside the window cleaning machine shell 1, the water pump sucks the external water into the nozzle mechanism, and then the nozzle mechanism sprays the water out, so that the water can be sprayed onto the window glass. In conjunction with the wiping of the window cleaning machine, the window can be wiped by spraying water.

[0023] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The nozzle mechanism includes a nozzle part 4 that is snap-connected to one end of the nozzle cover 3. Three connecting holes 6 are provided on the output port of the nozzle part 4. The two connecting holes 6 on both sides are symmetrically distributed in a fan shape with the middle connecting hole 6. The nozzle mechanism also includes three branch pipes 9 integrally formed on the nozzle part 4. The three branch pipes 9 are aligned one by one with the three connecting holes 6. A nozzle 7 is installed at the output end of the branch pipe 9. The nozzle mechanism also includes a main pipe 10 installed at the input end of the nozzle part 4. The outer wall of the main pipe 10 is threadedly connected to the water inlet connector 5, and the input end of the water inlet connector 5 is integrally formed with a water inlet nozzle 11.

[0024] In this embodiment: the water pump sucks external water into the water inlet nozzle 11, the water inlet nozzle 11 guides the water into the water inlet joint 5, and then the water enters the main pipe 10 through the water inlet joint 5, and is diverted to the three branch pipes 9 through the main pipe 10, and then sprayed out from the three nozzles 7. Since the three nozzles 7 are distributed in a fan shape, the water sprayed from the three nozzles 7 can be in a fan shape, forming a radial water spraying effect, which can effectively increase the contact area between the sprayed water and the glass, making it more convenient to wipe.

[0025] Please refer to Figure 6 The inner wall of the connecting cavity of the water inlet joint 5 is provided with a sealing ring 12 that contacts one end of the main pipe 10.

[0026] In this embodiment, the provision of the sealing ring 12 can prevent the water from being obliquely opened at the connection position between the main pipe 10 and the water inlet connector 5, thereby ensuring the water pressure of the water spray.

[0027] Please refer to Figure 6 A connection groove 8 for inserting the end of the nozzle component 4 is provided at the connection position between the nozzle cover 3 and the nozzle component 4.

[0028] In this embodiment, the design of the connecting groove 8 can facilitate the installation and connection between the nozzle component 4 and the nozzle cover 3.

[0029] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The end of the water inlet nozzle 11 away from the water inlet joint 5 is connected to the water pump through the water inlet pipe, and the input end of the water pump is connected to the external water source through a pipeline.

[0030] In this embodiment, the water pump serves as the power for water transmission, thereby delivering the external water to the nozzle mechanism, and the water is then sprayed onto the glass through the nozzle mechanism.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
