DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0026] Please see attached Figure 1 To Attachment Figure 4 The present embodiment provides a window cleaning machine with a double atomizing nozzle, comprising a water tank 1 and a double atomizing nozzle 2 connected to the water tank 1, the double atomizing nozzle 2 comprising a double atomizing bracket 21, a first atomizing channel 211 and a second atomizing channel 212 are provided on the double atomizing bracket 21, a first atomizing sheet 22 is provided in the first atomizing channel 211, a second atomizing sheet 23 is provided in the second atomizing channel 212, the first atomizing channel 211 and the second atomizing channel 212 are respectively connected to the water tank 1, and the first atomizing channel 211 and the second atomizing channel 212 are arranged to be inclined to each other so that the water mist path sprayed from the first atomizing channel 211 and the water mist path sprayed from the second atomizing channel 212 intersect with each other. A window cleaning machine with dual atomizing nozzles in the present embodiment has dual atomizing nozzles 2, which can spray water mist from a first atomizing channel 211 and a second atomizing channel 212 at the same time, and the water mist paths sprayed from the two atomizing channels are cross-arranged, with a large atomization range and a large spraying and wetting area, which can effectively improve the cleaning efficiency of the windows.

[0027] In order to further increase the atomization range, the water tank 1 in this embodiment is provided with a first water outlet 11 and a second water outlet 12, the first atomization channel 211 and the second atomization channel 212 are respectively provided at both ends of the dual atomization bracket 21, the first atomization channel 211 is connected to the first water outlet 11, and the second atomization channel 212 is connected to the second water outlet 12 through a connecting pipe 24.

[0028] Specifically, in the present embodiment, the first water outlet 11 and the second water outlet 12 on the water tank 1 are arranged adjacent to each other, and the double atomization bracket 21 is arranged on one side of the water tank 1. Since the first atomization channel 211 and the second atomization channel 212 are respectively arranged at the two ends of the double atomization bracket 21, the first atomization channel 211 is closer to the water tank 1, and the second atomization channel 212 is farther from the water tank 1. The first atomization channel 211 is connected to the first water outlet 11 by a direct connection, and the second atomization channel 212 is connected to the second water outlet 12 by a connecting pipe 24. Such an arrangement can increase the distance between the first atomization channel 211 and the second atomization channel 212 as much as possible, so that the atomization range is wider. In the present embodiment, the connecting pipe 24 can be a rubber hose, a plastic hose, a composite hose, etc. As a preferred embodiment, the present embodiment adopts a silicone hose, which is resistant to high and low temperatures and has good flexibility and chemical resistance.

[0029] Further, in order to realize the convenient connection between the first atomizing channel 211 and the first water outlet 11, in the present embodiment, the first water outlet 11 is provided with a first sleeve pipe 111 for being sleeved with the first atomizing channel 211 and a first limit plate 112 extending and protruding along the circumferential direction of the first sleeve pipe 111. Specifically, the first atomizing channel 211 is tubular, and when installed, the first sleeve pipe 111 is sleeved in the first atomizing channel 211, so that the end of the first atomizing channel 211 is against the first limit plate 112, and a sealing gasket is provided between the first atomizing channel 211 and the first limit plate 112, and the sealing gasket is made of silicone, and water leakage is effectively prevented by the sealing gasket. In addition, in order to achieve better installation and water discharge effect, the first sleeve pipe 111 and the first limit plate 112 are both tilted, and the tilt angle thereof is the same as the tilt angle of the first atomizing channel 211, so that the alignment installation is more convenient and quick, and the water discharge can be smoother and more stable.

[0030] Further, in order to realize the convenient connection between the second atomization channel 212 and the second water outlet 12, in the present embodiment, a second sleeve pipe 121 is provided on the second water outlet 12, and a switching elbow pipe 213 communicating with the second atomization channel 212 is provided on the double atomization bracket 21, and one end of the connecting pipe 24 is connected to the second sleeve pipe 121, and the other end is connected to the switching elbow pipe 213. In the present embodiment, the switching elbow pipe 213 is connected to the second atomization channel 212 and is integrally formed. By setting the switching elbow pipe 213, the water of the second water outlet 12 can be effectively guided to the second atomization channel 212. At the same time, since the end of the switching elbow 213 away from the second atomization channel 212 is opposite to the second sleeve pipe 121 on the second water outlet 12, during installation, it is only necessary to sleeve one end of the connecting pipe 24 with the switching elbow 213, and sleeve the other end of the connecting pipe 24 with the second sleeve pipe 121, and the structure is simple and the installation is convenient. In this embodiment, the connecting pipe 24 is interference-connected with the transfer elbow 213, and the connecting pipe 24 is interference-connected with the second sleeve pipe 121. In addition, by providing the transfer elbow 213, the connection structure between the second atomizing channel 212 and the second water outlet 12 can be made more compact, and the space utilization rate is high.

[0031] Furthermore, in this embodiment, the diameter of the first water outlet 11 is smaller than the diameter of the first atomizing channel 211, and the diameter of the second water outlet 12 is smaller than the diameter of the second atomizing channel 212. Thus, the first atomizing sheet 22 disposed in the first atomizing channel 211 can be effectively prevented from being separated from the first atomizing channel 211 and entering the water tank 1 through the first water outlet 11, and the second atomizing sheet 23 disposed in the second atomizing channel 212 can be effectively prevented from being separated from the second atomizing channel 212 and entering the water tank 1 through the second water outlet 12.

[0032] Furthermore, in this embodiment, the diameter of the first water outlet 11 is smaller than the diameter of the second water outlet 12. Since the first atomizing channel 211 is closer to the first water outlet 11 and the water delivery stroke is shorter, and the second atomizing channel 212 is farther from the second water outlet 12 and the water delivery stroke is longer, by setting the diameter of the first water outlet 11 smaller than the diameter of the second water outlet 12, the water mist output of the first atomizing channel 211 and the second atomizing channel 212 can be kept balanced, thereby improving the double atomization effect.

[0033] Furthermore, in order to facilitate the installation and disassembly of the first atomizing sheet 22 and the second atomizing sheet 23, in the present embodiment, the dual atomizing nozzle 2 also includes an atomizing sheet fixing pressing piece 25 detachably connected to the dual atomizing bracket 21, and the atomizing sheet fixing pressing piece 25 is provided with a first pressing block 251 for pressing and fixing the first atomizing sheet 22 in the first atomizing channel 211 and a second pressing block 252 for pressing and fixing the second atomizing sheet 23 in the second atomizing channel 212, the first pressing block 251 is provided with a first pressing block channel 253 communicating with the first atomizing channel 211, the second pressing block 252 is provided with a second pressing block channel 254 communicating with the second atomizing channel 212, and the first pressing block channel 253 and the second pressing block channel 254 are arranged to be inclined to each other so that the water mist path sprayed from the first pressing block channel 253 and the water mist path sprayed from the second pressing block channel 254 intersect with each other. During installation, the first atomizing sheet 22 is placed in the first atomizing channel 211 of the double atomizing bracket 21, and the second atomizing sheet 23 is placed in the second atomizing channel 212 of the double atomizing bracket 21, and then the first pressing block 251 of the atomizing sheet fixing pressing piece 25 is aligned with the first atomizing channel 211, and the second pressing block 252 of the atomizing sheet fixing pressing piece 25 is aligned with the second atomizing channel 212, and then the atomizing sheet fixing pressing piece 25 and the double atomizing bracket 21 are locked, at which time the first pressing block 251 presses and fixes the first atomizing sheet 22 in the first atomizing channel 211, and the second pressing block 252 presses and fixes the second atomizing sheet 23 in the second atomizing channel 212. The structure is simple, and the first atomizing sheet 22 and the second atomizing sheet 23 can be quickly installed and disassembled. After installation, the water in the water tank 1 enters the first atomizing channel 211 through the first water outlet 11 and is atomized by the first atomizing plate 22 before being sprayed out from the first pressing block channel 253. At the same time, the water in the water tank 1 enters the second atomizing channel 212 through the second water outlet 12 and is atomized by the second atomizing plate 23 before being sprayed out from the second pressing block channel 254. The water mists in the two paths are sprayed crosswise, which effectively expands the atomization range.

[0034] Furthermore, the first press block channel 253 is provided with a first press block water inlet 2531 and a first press block water outlet 2532, and the diameter of the first press block channel 253 gradually increases from the first press block water inlet 2531 to the first press block water outlet 2532, and the second press block channel 254 is provided with a second press block water inlet 2541 and a second press block water outlet 2542, and the diameter of the second press block channel 254 gradually increases from the second press block water inlet 2541 to the second press block water outlet 2542, which is beneficial to increase the atomization range.

[0035] Furthermore, in the present embodiment, in order to obtain a better atomization and wetting effect, the first atomization channel 211 and the second atomization channel 212 are arranged to be relatively inclined to form a cross water mist, and the first atomization channel 211 and the second atomization channel 212 are arranged to be inclined in a direction close to the window, which is conducive to making the water mist fall on the window; similarly, the first pressing block channel 253 and the second pressing block channel 254 are arranged to be relatively inclined to form a cross water mist, and the first pressing block channel 253 and the second pressing block channel 254 are arranged to be inclined in a direction close to the window, which is conducive to making the water mist fall on the window, thereby achieving a better atomization effect.

[0036] Furthermore, the dual atomization bracket 21 is clamped with the atomization sheet fixing pressure piece 25. Compared with the bolt fixing method, the clamping method is more convenient and quick to install and disassemble. Specifically, the dual atomization bracket 21 and the atomization sheet fixing pressure piece 25 are clamped together by the elastic clamping arm and the clamping hole buckle structure. The elastic clamping arm can be provided on the dual atomization bracket 21, and the clamping hole is provided on the atomization sheet fixing pressure piece 25, or the clamping hole is provided on the dual atomization bracket 21, and the elastic clamping arm is provided on the atomization sheet fixing pressure piece 25. In this embodiment, the structure in which the clamping hole is provided on the dual atomization bracket 21 and the elastic clamping arm is provided on the atomization sheet fixing pressure piece 25 is simple in structure and easy to install.

[0037] Furthermore, the window cleaning machine of this embodiment includes an upper shell 3 and a lower shell 4, a water tank 1 and a double atomizing nozzle 2 are installed between the upper shell 3 and the lower shell 4, wherein two double atomizing nozzles 2 are provided, and the two double atomizing nozzles 2 are respectively arranged on both sides of the water tank 1. The overall structure is compact and the space utilization rate is high. The double atomizing nozzles 2 located on both sides of the water tank 1 work simultaneously, the atomization effect is better, and the atomization efficiency is further improved.

[0038] The working principle of this embodiment is as follows:

[0039] During installation, the first atomization channel 211 on the double atomization bracket 21 is sleeved with the first sleeve 111 on the first water outlet 11 in the water tank 1, so that the end of the first atomization channel 211 is against the first limiting plate 112, and a sealing gasket is arranged between the first atomization channel 211 and the first limiting plate 112 to achieve pre-compression and prevent water leakage. Then, the first atomization sheet 22 is placed in the first atomization channel 211, and the first atomization sheet 22 is pressed by the first pressing block 251 on the atomization sheet fixing pressing piece 25 to further prevent water leakage. At the same time, the adapter elbow 213 connected to the second atomization channel 212 on the double atomization bracket 21 is interference-connected with one end of the connecting pipe 24, and the second sleeve pipe 121 on the second water outlet 12 in the water tank 1 is interference-connected with the other end of the connecting pipe 24. Then, the second atomization sheet 23 is placed in the second atomization channel 212, and the second atomization sheet 23 is pressed by the second pressing block 252 on the atomization sheet fixing pressing piece 25.

[0040] When in use, the water in the water tank 1 enters the first atomizing channel 211 from the first water outlet 11 through the first sleeve 111, and is atomized by the first atomizing sheet 22 before being sprayed out from the first pressing block channel 253. At the same time, the water in the water tank 1 enters the second atomizing channel 212 from the second water outlet 12 through the second sleeve 121, the connecting pipe 24, and the transfer elbow 213, and is atomized by the second atomizing sheet 23 before being sprayed out from the second pressing block channel 254. The water mists of the two paths are sprayed crosswise, which effectively expands the atomization range.
